J Clin Microbiol 2023 61 (12) e0079923 In 2017, the Centers for Disease Control and Prevention (CDC) established the Antimicrobial Resistance Laboratory Network to improve domestic detection of multidrug-resistant organisms. CDC and four laboratories evaluated a commercial broth microdilution panel. Antimicrobial susceptibility testing using the Sensititre GN7F (ThermoFisher Scientific, Lenexa, KS) was evaluated by testing 100 CDC and Food and Drug Administration AR Isolate Bank isolates [40 Enterobacterales (ENT), 30 Pseudomonas aeruginosa (PSA), and 30 Acinetobacter baumannii (ACB)]. We assessed multiple amounts of transfer volume (TV) between the inoculum and tubed 11-mL cation-adjusted Mueller-Hinton broth: 1 µL [tribe Proteeae (P-tribe) only] and 10, 30, and 50 µL, resulting in respective CFU per milliter of 1 × 10(4), 1 × 10(5), 3 × 10(5), and 5 × 10(5). Four TV combinations were analyzed: standard (STD) [1 µL (P-tribe) and 10 µL], enhanced standard (E-STD) [1 µL (P-tribe) and 30 µL], 30 µL, and 50 µL. Essential agreement (EA), categorical agreement, major error (ME), and very major error (VME) were analyzed by organism then TVs. For ENT, the average EA across laboratories was <90% for 7 of 15 β-lactams using STD and E-STD TVs. As TVs increased, EA increased (>90%), and VMEs decreased. For PSA, EA improved as TVs increased; however, MEs also increased. For ACB, increased TVs provided slight EA improvements; all TVs yielded multiple VMEs and MEs. For ENT and ACB, Minimum inhibitory concentrations (MICs) trended downward using a 1 or 10 µL TV; there were no obvious MIC trends by TV for PSA. The public health and clinical consequences of missing resistance warrant increased TV of 30 µL for the GN7F, particularly for P-tribe, despite being considered "off-label" use. |

Lancet Microbe 2023 4 (12) e1035-e1039 Nearly a century after the beginning of the antibiotic era, which has been associated with unparalleled improvements in human health and reductions in mortality associated with infection, the dwindling pipeline for new antibiotic classes coupled with the inevitable spread of antimicrobial resistance (AMR) poses a major global challenge. Historically, surveillance of bacteria with AMR typically relied on phenotypic analysis of isolates taken from infected individuals, which provides only a low-resolution view of the epidemiology behind an individual infection or wider outbreak. Recent years have seen increasing adoption of powerful new genomic technologies with the potential to revolutionise AMR surveillance by providing a high-resolution picture of the AMR profile of the bacteria causing infections and providing real-time actionable information for treating and preventing infection. However, many barriers remain to be overcome before genomic technologies can be adopted as a standard part of routine AMR surveillance around the world. Accordingly, the Surveillance and Epidemiology of Drug-resistant Infections Consortium convened an expert working group to assess the benefits and challenges of using genomics for AMR surveillance. In this Series, we detail these discussions and provide recommendations from the working group that can help to realise the massive potential benefits for genomics in surveillance of AMR. |

Jauneikaite E , Baker KS , Nunn JG , Midega JT , Hsu LY , Singh SR , Halpin AL , Hopkins KL , Price JR , Srikantiah P , Egyir B , Okeke IN , Holt KE , Peacock SJ , Feasey NA . Lancet Microbe 2023 4 (12) e1040-e1046 Integration of genomic technologies into routine antimicrobial resistance (AMR) surveillance in health-care facilities has the potential to generate rapid, actionable information for patient management and inform infection prevention and control measures in near real time. However, substantial challenges limit the implementation of genomics for AMR surveillance in clinical settings. Through a workshop series and online consultation, international experts from across the AMR and pathogen genomics fields convened to review the evidence base underpinning the use of genomics for AMR surveillance in a range of settings. Here, we summarise the identified challenges and potential benefits of genomic AMR surveillance in health-care settings, and outline the recommendations of the working group to realise this potential. These recommendations include the definition of viable and cost-effective use cases for genomic AMR surveillance, strengthening training competencies (particularly in bioinformatics), and building capacity at local, national, and regional levels using hub and spoke models. |
Comparison of carbapenem-susceptible and carbapenem-resistant Enterobacterales at nine sites in the USA, 2013-2016: a resource for antimicrobial resistance investigators
Lutgring JD , Kent AG , Bowers JR , Jasso-Selles DE , Albrecht V , Stevens VA , Pfeiffer A , Barnes R , Engelthaler DM , Johnson JK , Gargis AS , Rasheed JK , Limbago BM , Elkins CA , Karlsson M , Halpin AL . Microb Genom 2023 9 (11) Carbapenem-resistant Enterobacterales (CRE) are an urgent public health threat. Genomic sequencing is an important tool for investigating CRE. Through the Division of Healthcare Quality Promotion Sentinel Surveillance system, we collected CRE and carbapenem-susceptible Enterobacterales (CSE) from nine clinical laboratories in the USA from 2013 to 2016 and analysed both phenotypic and genomic sequencing data for 680 isolates. We describe the molecular epidemiology and antimicrobial susceptibility testing (AST) data of this collection of isolates. We also performed a phenotype-genotype correlation for the carbapenems and evaluated the presence of virulence genes in Klebsiella pneumoniae complex isolates. These AST and genomic sequencing data can be used to compare and contrast CRE and CSE at these sites and serve as a resource for the antimicrobial resistance research community. |
Trends in cardiovascular disease mortality rates and excess deaths, 2010-2022
Woodruff RC , Tong X , Khan SS , Shah NS , Jackson SL , Loustalot F , Vaughan AS . Am J Prev Med 2023 INTRODUCTION: Cardiovascular disease (CVD) mortality increased during the initial years of the coronavirus disease 2019 (COVID-19) pandemic, but whether these trends endured in 2022 is unknown. The analysis describes temporal trends in CVD death rates from 2010 to 2022 and estimates excess CVD deaths from 2020 to 2022. METHODS: Using national mortality data from the National Vital Statistics System, deaths among adults aged ≥35 years were classified by underlying cause of death International Classification of Diseases 10(th) Revision codes for CVD (I00-I99), heart disease (I00-I09, I11, I13, I20-I51), and stroke (I60-I69). Analyses in Joinpoint software identified trends in CVD age-adjusted mortality rates (AAMR) per 100,000 and estimated the number of excess CVD deaths from 2020 to 2022. RESULTS: During 2010-2022, 10,951,403 CVD deaths occurred (75.6% heart disease, 16.9% stroke). The national CVD AAMR declined by 8.9% from 2010 to 2019 (456.6 to 416.0 per 100,000) and then increased by 9.3% from 2019 to 2022 to 454.5 per 100,000, which approximated the 2010 rate (456.7 per 100,000). From 2020 to 2022, 228,524 excess CVD deaths occurred, which was 9.0% more CVD deaths than expected based on trends from 2010 to 2019. Results varied by CVD subtype and population subgroup. CONCLUSIONS: Despite stabilization of the public health emergency, declines in CVD mortality rates reversed in 2020 and remained high in 2022, representing almost a decade of lost progress and over 228,000 excess CVD deaths. Findings underscore the importance of prioritizing prevention and management of CVD to improve outcomes. |
Prevalence of pharmacologic and nonpharmacologic pain management therapies among adults with chronic pain-United States, 2020
Rikard SM , Strahan AE , Schmit KM , Guy GP Jr . Ann Intern Med 2023 176 (11) 1571-1575 Background: In 2021, approximately 1 in 5 adults in the United States experienced chronic pain (1). The Centers for Disease Control and Prevention’s “CDC Clinical Practice Guideline for Prescribing Opioids for Pain — United States, 2022” (2) recommends maximizing nonpharmacologic and nonopioid therapies for pain as appropriate for the specific condition and patient. Whereas previous research reported the prevalence of use of nonpharmacologic and opioid therapies for pain (3), this study adds information about prescription nonopioids, over-the-counter pain relievers, and exercise. | | Objective: To estimate the prevalence of use of pharmacologic and nonpharmacologic therapies among adults with chronic pain in the United States. | | Methods and Findings: We used the 2020 National Health Interview Survey (NHIS) (31 568 total respondents) to identify adults who self-reported pain on most days or every day in the past 3 months (unweighted n = 7422) (4). Respondents reported use of pharmacologic (prescription opioids, prescription nonopioids, over-the-counter pain relievers) and nonpharmacologic (physical or occupational therapy [PT/OT], cognitive behavioral therapy [CBT], exercise, complementary therapies) pain management therapies in the past 3 months. We report therapy prevalence overall and by demographic characteristics. Adjusted prevalence was estimated using predictive margins from multivariable logistic regression models. All analyses account for the complex NHIS survey design. This study was exempt from institutional review board review. | | In 2020, approximately 54 million adults self-reported chronic pain. Among pharmacologic therapies, use of over-the-counter pain relievers in the past 3 months was most prevalent (75.5%), followed by prescription nonopioids (31.3%) and prescription opioids (13.5%) (Table 1). Among nonpharmacologic therapies, exercise was most prevalent (55.0%), followed by complementary therapies (36.7%), PT/OT (17.2%), and CBT (2.6%). Pharmacologic therapy use alone was reported by 26.6% of adults, with most (22.4%) reporting nonopioid use only and 1.0% reporting opioid use only. Most adults (60.2%) reported using both pharmacologic and nonpharmacologic therapies, with 50.9% reporting nonopioid and nonpharmacologic therapy use and 7.7% reporting combined use of opioids, nonopioids, and nonpharmacologic therapy. |
Performance of a tic screening tool (MOVeIT) in comparison to expert clinician assessment in a developmental-behavioral pediatrics clinic sample
Vermilion JA , Bitsko RH , Danielson ML , Bonifacio KP , Dean SL , Hyman SL , Augustine EF , Mink JW , Morrison PE , Vierhile AE , Sulkes SB , van Wijngaarden E , Adams HR . Evid Based Pract Child Adolesc Ment Health 2023 Youth with intellectual and developmental disabilities typically have higher rates of tics and stereotypies compared to children with otherwise typical development. Differentiating between these two pediatric movement disorders can be challenging due to overlapping clinical features, but is relevant due to distinct treatment modalities. The current study evaluated sensitivity and specificity of a tic screening measure, the Motor or Vocal Inventory of Tics (MOVeIT) in a pediatric sample enriched for stereotypy and tics. Children (n = 199, age 2–15 years old) receiving care in a developmental-behavioral pediatrics clinic underwent a gold-standard diagnostic assessment by a tic expert; these evaluations were compared to the MOVeIT. The MOVeIT demonstrated good sensitivity (89.8%) and relatively lower specificity (57.1%) compared to tic expert for detecting tics in the overall sample. Specificity of the MOVeIT to identify tics improved to 75% when excluding children with co-occurring stereotypy. For children with tics and co-occurring stereotypy, sensitivity remained high (91.9%) but specificity was low (39.1%). The area under the curve (AUC) value to detect tics on the MOVeIT compared to the tic expert gold standard was significantly higher for children without stereotypy (AUC = 85.7%) than those with stereotypy (AUC = 64.3%, p <.01). Overall, the ability to detect tics was better in those without co-occurring stereotypy symptoms. Further work is needed to establish the utility of the MOVeIT in populations where there is a high likelihood of co-occurring tics and stereotypy and in general population settings. Accurate distinction between tics and stereotypy will guide choices for intervention and anticipatory guidance for families. © 2023 Society of Clinical Child & Adolescent Psychology. |
Trends in the prevalence of chronic obstructive pulmonary disease among adults aged ≥18 years - United States, 2011-2021
Liu Y , Carlson SA , Watson KB , Xu F , Greenlund KJ . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1250-1256 Chronic obstructive pulmonary disease (COPD) is a leading cause of death in the United States. Overall COPD prevalence declined during 1999-2011. Trends in COPD prevalence during the previous decade have not been reported. CDC analyzed 2011-2021 Behavioral Risk Factor Surveillance System data to assess trends and differences in self-reported physician-diagnosed COPD prevalence among U.S. adults aged ≥18 years. Age-standardized prevalence of COPD did not change significantly from 2011 (6.1%) to 2021 (6.0%). Prevalence was stable for most states and subgroups; however, it decreased significantly among adults aged 18-44 years (average annual percent change [AAPC] = -2.0%) and increased significantly among those aged ≥75 years (AAPC = 1.3%), those living in micropolitan counties (0.8%), and among current (1.5%) or former (1.2%) smokers. COPD prevalence remained elevated in the following groups: women, adults aged ≥65 years, those with a lower education level, unable to work, living in rural areas, and who ever smoked. Evidence-based strategies, especially those tailored for adults disproportionately affected, can reduce COPD prevalence, and address the continued need for prevention, early diagnosis, treatment, and management. |
The frequency of undiagnosed celiac disease in youth with type 1 diabetes and its association with diabetic retinopathy: The SEARCH for Diabetes in Youth Study
Brady RP , Jensen ET , Rigdon J , Crimmins NA , Mallon D , Dolan LM , Imperatore G , Kahkoska AR , Mottl AK , Honor A , Pettitt DJ , Merjaneh L , Dabelea D , Shah AS . Pediatr Diabetes 2023 2023 Aims. Celiac disease (CD) in adults with type 1 diabetes has been associated with increased cardiovascular risk and the earlier occurrence of diabetes-associated complications. In the Search for Diabetes in Youth study, we aimed to assess the frequency of CD and the potential for undiagnosed CD among youth with childhood onset type 1 diabetes. In addition, we assessed the burden of cardiovascular risk factors and diabetes-associated complications in youth with type 1 diabetes by CD status and IgA tissue transglutaminase autoantibody (tTGA) levels. Methods. 2,444 youths with type 1 diabetes completed a CD questionnaire and underwent tTGA testing. Integrating the celiac disease questionnaire and tTGA results for this cross-sectional analysis, participants were categorized as follows: (1) reported CD; (2) seropositive for CD (no reported CD and seropositive tTGA); and (3) type 1 diabetes only (comparison group: no reported CD and seronegative tTGA). Subanalyses were performed on those with no reported CD and tTGA ≥10x ULN, designated potentially undiagnosed CD. Cardiovascular risk factors and diabetes-associated complications were evaluated by CD status and tTGA levels utilizing a Poisson model to estimate relative risk. Results. Reported CD in youths with type 1 diabetes was 7%. Seropositivity for tTGA with no reported CD was present in 4%, and 1.2% had potentially undiagnosed CD. Youths with potentially undiagnosed CD had a 2.69x higher risk of diabetic retinopathy than comparison group. In addition, CD with tTGA <0.05 (controlled CD) was associated with lower HbA1c. Conclusions. Undiagnosed CD is likely present in youths with type 1 diabetes and potentially undiagnosed CD is associated with a higher risk of diabetic retinopathy. These findings indicate the importance of routine screening for CD in type 1 diabetes in youths. © 2023 Ryan P. Brady et al. |
Diabetes complications and cognitive function in young adults with youth-onset type 1 or type 2 diabetes: The SEARCH for Diabetes In Youth Study
Shapiro ALB , Bellatorre A , Dabelea D , Stafford JM , D'Agostino R , Shah AS , Urbina EM , Barrett CE , Pihoker C , Marcovina S , Liese AD , Mottl AK , Jensen ET , Wilkening G . Pediatr Diabetes 2023 2023 Aims/Hypotheses. People with type 1 (T1D) or type 2 diabetes (T2D) who also have diabetes complications can have pronounced cognitive deficits. It remains unknown, however, whether and how multiple diabetes complications co-occur with cognitive dysfunction, particularly in youth-onset diabetes. Methods. Using data from the SEARCH for Diabetes in Youth Study cohort, a prospective longitudinal cohort, we examined clustering of complications and their underlying clinical factors with performance on cognitive tests in young adults with youth-onset T1D or T2D. Cognition was assessed via the NIH Toolbox Cognition Battery. The main cognitive variables were age-corrected scores for composite fluid cognition and associated cognitive subdomains. Diabetes complications included retinopathy, microalbuminuria, and peripheral neuropathy (PN). Lipids, systolic blood pressure (SBP), hemoglobin A1c, and other clinical factors were included in the analyses. Clustering was applied separately to each group (T1D = 646; T2D = 165). A three-cluster (C) solution was identified for each diabetes type. Mean values and frequencies of all factors were compared between resulting clusters. Results. The average age-corrected score for composite fluid cognition differed significantly across clusters for each group (p<0.001). People with T1D and the lowest average fluid cognition scores had the highest frequency of self-reporting at least one episode of hypoglycemia in the year preceding cognitive testing and the highest prevalence of PN. Persons with T2D and the lowest average fluid cognition scores had the highest SBP, the highest central systolic and diastolic blood pressures, and highest prevalence of PN. Conclusions/Interpretations. These findings highlight shared (PN) and unique factors (hypoglycemia in T1D; SBP in T2D) that could be targeted to potentially mitigate cognitive issues in young people with youth-onset diabetes. © 2023 Allison L.

Excess burden of poverty and hypertension, by race and ethnicity, on the prevalence of cardiovascular disease
Sells ML , Blum E , Perry GS , Eke P , Presley-Cantrell L . Prev Chronic Dis 2023 20 E109 INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death in the United States. Certain demographic characteristics are associated with disparities in CVD and its risk factors, which may interact with specific social determinants of health (SDOH). We examined the association of a single SDOH (ie, poverty level) with diagnosed CVD morbidity and the joint influence of poverty and hypertension on the prevalence of CVD morbidity among non-Hispanic Black, non-Hispanic White, and Hispanic people aged 30 years or older. METHODS: We used data from the National Health and Nutrition Examination Survey collected during 1999 to 2018. We assessed the prevalence of diagnosed CVD morbidity (eg, self-reported coronary heart disease, angina, myocardial infarction, or stroke) by using a Poisson family with a log link regression model. We calculated the additive interaction of poverty level with hypertension on diagnosed CVD morbidity for each race and ethnicity. RESULTS: We found excess CVD morbidity among non-Hispanic Black and Hispanic people experiencing poverty and diagnosed with hypertension compared with their non-Hispanic White counterparts. Multivariate analysis found a higher prevalence of CVD among participants of all races and ethnicities who were experiencing poverty and among non-Hispanic White people who had less than a college education. In addition, age, hypertension, poverty, smoking, and weight were significant predictors of the prevalence of CVD morbidity among all racial and ethnic groups. CONCLUSION: Changes to interventions, policies, and research may be needed to address the effect of key indicators of health disparities and specific SDOH, such as poverty level, that intersect with hypertension and contribute to excess CVD morbidity among people of some racial and ethnic groups, particularly non-Hispanic Black and Hispanic populations. |
Heterogenous transmission and seroprevalence of SARS-CoV-2 in two demographically diverse populations with low vaccination uptake in Kenya, March and June 2021

Gates Open Res 2023 7 101 BACKGROUND: SARS-CoV-2 has extensively spread in cities and rural communities, and studies are needed to quantify exposure in the population. We report seroprevalence of SARS-CoV-2 in two well-characterized populations in Kenya at two time points. These data inform the design and delivery of public health mitigation measures. METHODS: Leveraging on existing population based infectious disease surveillance (PBIDS) in two demographically diverse settings, a rural site in western Kenya in Asembo, Siaya County, and an urban informal settlement in Kibera, Nairobi County, we set up a longitudinal cohort of randomly selected households with serial sampling of all consenting household members in March and June/July 2021. Both sites included 1,794 and 1,638 participants in the March and June/July 2021, respectively. Individual seroprevalence of SARS-CoV-2 antibodies was expressed as a percentage of the seropositive among the individuals tested, accounting for household clustering and weighted by the PBIDS age and sex distribution. RESULTS: Overall weighted individual seroprevalence increased from 56.2% (95%CI: 52.1, 60.2%) in March 2021 to 63.9% (95%CI: 59.5, 68.0%) in June 2021 in Kibera. For Asembo, the seroprevalence almost doubled from 26.0% (95%CI: 22.4, 30.0%) in March 2021 to 48.7% (95%CI: 44.3, 53.2%) in July 2021. Seroprevalence was highly heterogeneous by age and geography in these populations-higher seroprevalence was observed in the urban informal settlement (compared to the rural setting), and children aged <10 years had the lowest seroprevalence in both sites. Only 1.2% and 1.6% of the study participants reported receipt of at least one dose of the COVID-19 vaccine by the second round of serosurvey-none by the first round. CONCLUSIONS: In these two populations, SARS-CoV-2 seroprevalence increased in the first 16 months of the COVID-19 pandemic in Kenya. It is important to prioritize additional mitigation measures, such as vaccine distribution, in crowded and low socioeconomic settings. |
Mortality among persons with HIV in the United States during the COVID-19 pandemic: a population-level analysis
Viguerie A , Song R , Bosh K , Lyles CM , Farnham PG . J Acquir Immune Defic Syndr 2023 BACKGROUND: Whether the COVID-19 pandemic has had a disproportionate impact on mortality among persons with diagnosed HIV (PWDH) in United States is unclear. Through our macro-scale analysis, we seek to better understand how the COVID-19 pandemic affected mortality among PWDH. METHODS: We obtained mortality and population data for the years 2018-2020 from the National HIV Surveillance System (NHSS) for the U.S. PWDH population, and from publicly available data for the general population. We computed mortality rates and excess mortality for both the general and PWDH populations. Stratifications by age, race/ethnicity, and sex were considered. For each group, we determined whether the 2020 mortality rates and mortality risk ratio showed a statistically significant change from 2018-2019. RESULTS: Approximately 1550 excess deaths occurred among PWDH in 2020, with Black, Hispanic/Latino and PWDH 55 and older comprising the majority of excess deaths. Mortality rates increased in 2020 from 2018-2019 across the general population in all groups. Among PWDH, mortality rates either increased, or showed no statistically significant change. These increases were similar to, or smaller than, those observed in the general population, resulting in a 7.7% decrease in the mortality risk ratio between PWDH and the general population. CONCLUSIONS: While mortality rates among PWDH increased in 2020 relative to 2018-2019, the increases were smaller, or of similar magnitude, to those observed in the general population. We thus do not find evidence of elevated mortality risk from the COVID-19 pandemic among PWDH. These findings held across subpopulations stratified by age, sex, and racial/ethnic group. |
Oseltamivir may or may not reduce hospitalizations
Uyeki TM , Hui DSC , Lee N . JAMA Intern Med 2023 184 (1) 116 Hanula et al1 reported findings of a systematic review and meta-analysis that included 15 randomized clinical trials (RCTs) of oseltamivir treatment for outpatients with influenza (age ≥12 years). The authors found no association between oseltamivir treatment of laboratory-confirmed influenza and risk of hospitalization among 6295 total participants or in subanalyses of older participants (mean age, ≥65 years; relative risk [RR], 0.99; 95% CI, 0.19-5.13) or participants with high-risk comorbidities (RR, 0.90; 95% CI, 0.37-2.17). | | These study findings did not definitively determine whether oseltamivir treatment of outpatients with influenza reduces their risk of progression to severe disease.1 The included RCTs studied mild end points (eg, time to alleviation of symptoms, duration of uncomplicated influenza illness). Moreover, none of the RCTs were designed nor sufficiently powered to assess the end point of hospitalization and most were conducted among patients without increased risk for severe influenza complications. |
Notes from the field: A cluster of multi-strain invasive pneumococcal disease among persons experiencing homelessness and use of pneumococcal conjugate vaccine - El Paso County, Colorado, 2022
Callaway J , Durbin K , Zachary H , Barnes MM , Kobayashi M , Chochua S , Gayou N , Albanese B . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1277-1278 Persons experiencing homelessness are often at increased risk for invasive pneumococcal disease (IPD)* due to underlying health conditions or risk factors (risk conditions) (1,2). Homelessness alone is not an indication for pneumococcal vaccination according to current Advisory Committee on Immunization Practices (ACIP) recommendations (3): adults aged ≥65 years or 19–64 years with certain underlying medical conditions or risk factors† with no previous or unknown history of receipt of pneumococcal conjugate vaccine (PCV) should receive 1 dose of either 20-valent or 15-valent PCV (PCV20 or PCV15, respectively). On November 29, 2022, El Paso (Colorado) County Public Health (EPCPH) was informed by a single hospital of three cases of IPD among persons experiencing homelessness, with all illness onset dates occurring within a single week. |
Notes from the field: Diagnosis of congenital syphilis and syphilis among females of reproductive age before and during the COVID-19 pandemic - Chicago, 2015-2022
Cejtin HE , Warren EF , Guidry T , Boss K , Becht A , Tabidze I . MMWR Morb Mortal Wkly Rep 2023 72 (47) 1288-1289 Syphilis is a bacterial infection that is of particular concern during pregnancy because of the risk for transplacental fetal infection. Pregnancies complicated by untreated syphilis are at increased risk for adverse outcomes, including stillbirth and long-term physical and cognitive sequelae in the affected infant. After implementation of enhanced efforts (1) by the Chicago Department of Public Health (CDPH) to eliminate congenital syphilis, including improvements to the surveillance and case management system, the number of Chicago congenital syphilis cases steadily decreased during 2015–2019, despite national increases in congenital syphilis and local increases in syphilis among females of reproductive age.* In 2020, with the emergence of the COVID-19 pandemic, the trend in Chicago abruptly shifted, and cases of congenital syphilis increased during the next 3 years. |
Vital signs: Missed opportunities for preventing congenital syphilis - United States, 2022
McDonald R , O'Callaghan K , Torrone E , Barbee L , Grey J , Jackson D , Woodworth K , Olsen E , Ludovic J , Mayes N , Chen S , Wingard R , Johnson Jones M , Drame F , Bachmann L , Romaguera R , Mena L . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1269-1274 INTRODUCTION: Congenital syphilis cases in the United States increased 755% during 2012-2021. Syphilis during pregnancy can lead to stillbirth, miscarriage, infant death, and maternal and infant morbidity; these outcomes can be prevented through appropriate screening and treatment. METHODS: A cascading framework was used to identify and classify missed opportunities to prevent congenital syphilis among cases reported to CDC in 2022 through the National Notifiable Diseases Surveillance System. Data on testing and treatment during pregnancy and clinical manifestations present in the newborn were used to identify missed opportunities to prevent congenital syphilis. RESULTS: In 2022, a total of 3,761 cases of congenital syphilis in the United States were reported to CDC, including 231 (6%) stillbirths and 51 (1%) infant deaths. Lack of timely testing and adequate treatment during pregnancy contributed to 88% of cases of congenital syphilis. Testing and treatment gaps were present in the majority of cases across all races, ethnicities, and U.S. Census Bureau regions. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Addressing missed opportunities for prevention, primarily timely testing and appropriate treatment of syphilis during pregnancy, is important for reversing congenital syphilis trends in the United States. Implementing tailored strategies addressing missed opportunities at the local and national levels could substantially reduce congenital syphilis. |
A cluster of ocular syphilis cases with a common sex partner - Southwest Michigan, 2022
Nettleton WD , Kent JB , Lightheart K , Diesel JC . MMWR Morb Mortal Wkly Rep 2023 72 (47) 1281-1287 Untreated syphilis can lead to ocular syphilis, otosyphilis, and neurosyphilis, conditions resulting from Treponema pallidum infection of the eye, inner ear, or central nervous system. During March-July 2022, Michigan public health officials identified a cluster of ocular syphilis cases. The public health response included case investigation, partner notification, dissemination of health alerts, patient referral to a public health clinic for diagnosis and treatment, hospital care coordination, and specimen collection for T. pallidum molecular typing. Five cases occurred among southwest Michigan women, all of whom had the same male sex partner. The women were aged 40-60 years, HIV-negative, and identified as non-Hispanic White race; the disease was staged as early syphilis, and all patients were hospitalized and treated with intravenous penicillin. The common male sex partner was determined to have early latent syphilis and never developed ocular syphilis. No additional transmission was identified after the common male partner's treatment. Due to lack of genetic material in limited specimens, syphilis molecular typing was not possible. A common heterosexual partner in an ocular syphilis cluster has not been previously documented and suggests that an unidentified strain of T. pallidum might have been associated with increased risk for systemic manifestations of syphilis. A high index of clinical suspicion and thorough sexual history are critical to diagnosing ocular syphilis, otosyphilis, and neurosyphilis. Coordination of disease surveillance with disease intervention specialist investigation and treatment referral can interrupt syphilis transmission. |
Temporal trends in sociodemographic composition and land development within U.S. fenceline communities surrounding hazardous industrial facilities: 2001-2019
Southerland V , Zota AR , Parasram V , Alvarez C , Clement M , Anenberg S . Environ Res Lett 2023 18 (11) Unintended releases from industrial facilities can expose fenceline communities to hazardous substances, and distance between facilities and nearby residential development can play a role in preventing exposures. Here, we assess trends in fenceline community sociodemographic characteristics, land development, and the association between the two using sociodemographic data for census tracts (n = 34 068) surrounding 2457 petroleum refining and chemical manufacturing facilities between 2001 and 2019. We find a higher median growth in percentage of Latinx populations among fenceline communities compared to neighboring communities with no industrial facilities. The increase in the median percentage of Latinx populations within fenceline communities was six times higher than for White populations overall (+6 and +1 percentage points, respectively). Though the percentage of the Black populations did not change within fenceline communities over this period, we find a minor sustained higher percentage of Black residents within fenceline communities relative to neighboring communities (20% versus 19%, respectively). Employing a spatial autoregressive model with autoregressive disturbances, we find that an increase in community percentage Latinx population is associated with a decrease in the rate of land development. Comparing fenceline and neighboring communities, we conclude that Black and Latinx populations are disproportionately located near industrial facilities, potentially contributing to inequitable exposure to unintended chemical releases. Our work lends support to the value of considering of sociodemographic composition of fenceline communities when evaluating industrial facility hazards. © 2023 The Author(s).

Identifying workforce education, training, and outreach needs in decentralized wastewater and distributed water reuse
Holodak Jamie , Stanley Jacob K , Cox Alissa H , Groves Thomas W , Jantrania Anish , Moeller Jeffrey , Neset Kris , Walker Christopher , Zhang Harry , Heger Sara F , Brooks Bryan W . J Environ Health 2023 86 (5) 20-28 Although decentralized wastewater and distributed water reuse professionals represent a key part of environmental public health and environmental engineering, an understanding of workforce challenges has remained elusive. Here we begin to address the critical need of understanding education, training, and outreach needs for decentralized wastewater and distributed water reuse. We specifically engaged professionals working in health departments and other government agencies, industry, academia, and nongovernmental organizations. We examined workforce characteristics related to education, training, and outreach. We found that 37% of decentralized wastewater and distributed water reuse professionals plan to retire within 5 years, approximately 25% of these professionals do not hold any type of certification, and education and training are insufficient to meet current workforce demands. We further report 10 problem statements associated with timely education, training, and outreach needs, which represent important opportunities for improving the practice of decentralized wastewater and distributed water reuse. Strategic education, training, and outreach activities are necessary to ensure workforce preparedness, to promote education with owners of onsite technologies, and to expand advanced training and translational research programs in decentralized wastewater and distributed water reuse. Our findings can specifically support decision making aimed at sustaining and advancing the decentralized wastewater and distributed water reuse workforce. |
Profiling metal-induced genotoxic endpoints
Shoeb Mohammad , Zarus Gregory M , Abadin Henry E . J Environ Health 2023 86 (5) 30-35 Many toxic metals are involved in the initiation and progression of DNA damage that can result in the activation of DNA damage response machinery at double- and single-stranded DNA; this response can result in global and gene-specific DNA alteration. The toxicological profiles from the Agency for Toxic Substances and Disease Registry (ATSDR) and several other studies have demonstrated the influence of metal exposure-induced genotoxic endpoints and epigenetic modifications. Our review systematically summarizes accumulating evidence from ATSDR toxicological profiles and the available literature that demonstrate a possible induction of various genotoxic endpoints and metal exposures. We include in this article studies on chromium, arsenic, nickel, lead, mercury, and zinc. |
Mortality surveillance during Winter Storm Uri, United States - 2021
Hanchey A , Jiva S , Bayleyegn T , Schnall A . Disaster Med Public Health Prep 2023 17 e530 OBJECTIVE: On February 12, 2021, Winter Storm Uri hit the United States. To understand the disaster-related causes and circumstances of death, the Centers for Disease Control and Prevention (CDC) activated media mortality surveillance. METHODS: The team searched the internet daily for key terms related to Uri and compiled the information into a standardized media mortality surveillance database to conduct descriptive statistics. RESULTS: Between February 12 and March 2, 2021, the accessed media reported 136 Uri-related deaths from nine states. Most decedents were male (39%) and adults (62.5%). Exposure to extreme temperatures (47.1%) was the most common cause of death. Among indirect deaths, motor vehicle collision (12.5%), and carbon monoxide poisoning (7.4%) represented the top two circumstances. CONCLUSION: This was the first time CDC activated media mortality surveillance for a winter storm. Media mortality surveillance is useful in assessing the impact of a disaster and provides timely data for an all-hazards response approach. |
Genomic analysis of azithromycin-resistant Salmonella from food animals at slaughter and processing, and retail meats, 2011-2021, United States
Ge B , Mukherjee S , Li C , Harrison LB , Hsu CH , Tran TT , Whichard JM , Dessai U , Singh R , Gilbert JM , Strain EA , McDermott PF , Zhao S . Microbiol Spectr 2023 e0348523 Macrolides of different ring sizes are critically important antimicrobials for human medicine and veterinary medicine, though the widely used 15-membered ring azithromycin in humans is not approved for use in veterinary medicine. We document here the emergence of azithromycin-resistant Salmonella among the NARMS culture collections between 2011 and 2021 in food animals and retail meats, some with co-resistance to ceftriaxone or decreased susceptibility to ciprofloxacin. We also provide insights into the underlying genetic mechanisms and genomic contexts, including the first report of a novel combination of azithromycin resistance determinants and the characterization of multidrug-resistant plasmids. Further, we highlight the emergence of a multidrug-resistant Salmonella Newport clone in food animals (mainly cattle) with both azithromycin resistance and decreased susceptibility to ciprofloxacin. These findings contribute to a better understating of azithromycin resistance mechanisms in Salmonella and warrant further investigations on the drivers behind the emergence of resistant clones. |
Improving global health security through implementation of the National Action Plan for Health Security in Sierra Leone, 2018-2021: lessons from the field
Njuguna C , Vandi M , Singh T , Njeru I , Githuku J , Gachari W , Musoke R , Caulker V , Bunting-Graden J , Mahar M , Brown SM , Bah MA , Idriss MB , Talisuna A , Chamla D , Yoti Z , Sreedharan R , Suryantoro L , Gueye AS , Chungong S . BMC Public Health 2023 23 (1) 2178 BACKGROUND: All countries are required to implement International Health Regulations (IHR) through development and implementation of multi-year National Action Plans for Health Security (NAPHS). IHR implementation requires annual operational planning which involves several tools such as NAPHS, State Party Annual Report (SPAR), Joint External Evaluation (JEE) and WHO IHR Benchmarks tool. Sierra Leone has successfully improved IHR capacities across the years through successful annual operational planning using the above tools. We conducted a study to document and share the country's unique approach to implementation of NAPHS. METHODS: This was an observational study where the process of implementing and monitoring NAPHS in Sierra Leone was observed at the national level from 2018 to 2021. Data was obtained through review and analysis of NAPHS annual operational plans, quarterly review reports and annual IHR assessment reports. Available data was supplemented by information from key informants. Qualitative data was captured as notes and analysed for various themes while quantitative data was analyzed mainly for means and proportions. RESULTS: The overall national IHR Joint External Evaluation self-assessment score for human health improved from 44% in 2018 to 51% in 2019 and 57% in 2020. The score for the animal sector improved from 32% in 2018 to 43% in 2019 and 52% in 2020. A new JEE tool with new indicators was used in 2021 and the score for both human and animal sectors declined slightly to 51%. Key enablers of success included strong political commitment, whole-of-government approach, annual assessments using JEE tool, annual operational planning using WHO IHR Benchmarks tool and real time online monitoring of progress. Key challenges included disruption created by COVID-19 response, poor health infrastructure, low funding and inadequate health workforce. CONCLUSION: IHR annual operational planning and implementation using evidence-based data and tools can facilitate strengthening of IHR capacity and should be encouraged. |
Assessing hand hygiene knowledge, attitudes, and behaviors among Guatemalan primary school students in the context of the COVID-19 pandemic
Pieters MM , Fahsen N , Quezada R , Pratt C , Craig C , McDavid K , Vega Ocasio D , Hug C , Cordón-Rosales C , Lozier MJ . BMC Public Health 2023 23 (1) 2252 BACKGROUND: Hand hygiene (HH) is an important practice that prevents transmission of infectious diseases, such as COVID-19. However, in resource-limited areas, where water and soap are not always available, it can be difficult to practice HH correctly and at appropriate moments. The purpose of this study was to assess HH knowledge and behaviors among students from six elementary schools in Quetzaltenango, Guatemala to identify gaps that could later inform interventions to improve HH. METHODS: We conducted knowledge, attitude, and practices (KAP) surveys among primary school students during the COVID-19 pandemic in July 2022. We also observed students' HH practices at three different moments during the day, making note of the use of the HH station and materials, duration of handwashing, presence of a HH assistant, and the students' sex. We also used the Quantitative Personal Hygiene Assessment Tool (qPHAT), to measure hand dirtiness before eating, after restroom use, and upon arriving to school. RESULTS: We surveyed 109 students across six schools. Mean scores were 4 out of 5 for knowledge, 8 out of 8 for attitudes, and 6 out of 7 for HH practices. Most students identified "before eating" as a critical moment for HH (68.8%), fewer identified "after restroom use" (31.2%), and no students mentioned HH being necessary "after coughing or sneezing". We observed 326 HH opportunities of which 51.2% performed correct HH (used water and soap for at least 20 s or used alcohol-based hand rub, where materials were available). We collected 82 qPHAT hand swabs. A Kruskal Wallis test revealed a significant difference in hand dirtiness between entering the school and after restroom use (p = 0.017), but no significant difference before eating and after entering the school (p = 0.6988). CONCLUSIONS: The results from the KAP survey show high scores, however correct identification of key moments for HH was relatively uncommon, especially after restroom use and after coughing or sneezing. Additionally, half of HH opportunities observed had correct HH practices and on average, hands were dirtiest when arriving at school. These findings will inform interventions to improve HH practices and behaviors, which will be evaluated with follow-up data collection. |

Paid sick leave and self-reported depression and anxiety: Evidence from a nationally representative longitudinal survey
Asfaw A . Am J Prev Med 2023 INTRODUCTION: The objective of this study was to explore the association between access to paid sick leave (AtPSL) and self-reported feelings of depression and anxiety in a nationally representative U.S. working population. METHODS: In 2023, this study examined data from the 2019-2020 Longitudinal National Health Interview Survey. A Generalized Linear Latent and Mixed Model (GLLAMM) was used to analyze the longitudinal data. RESULTS: The descriptive analysis of population averages showed that fewer workers with AtPSL reported daily feelings of depression (45%), anxiety (24%), and both depression and anxiety (52%) than workers without AtPSL. According to the GLLAMM analysis, the odds of workers with AtPSL self-reporting feelings of daily depression, anxiety, and both were 48%, 27%, and 51% lower, respectively, than workers without AtPSL. This analysis controlled for different demographic and socio-economic variables. Robustness analysis demonstrated that these associations persisted when the outcome variables were measured in terms of self-reported feelings of weekly depression and anxiety. CONCLUSIONS: The role of mental health in improving overall well-being and the recognition of AtPSL as a social justice issue have reinforced the importance of providing paid sick leave to help protect the mental health status of workers. This study, using a unique longitudinal data set, found that AtPSL was associated with a lower prevalence of self-reported daily or weekly feelings of depression and anxiety. |
Building diversity, equity, inclusion, and accessibility capacity: Resources to promote best practices among professionals in scholarly publishing
Jack L Jr , Olson PJ , Baskin PK , Iwuchukwu OF . Prev Chronic Dis 2023 20 E105 The Council of Science Editors (CSE) is an international organization of more than 500 editorial professionals in the scientific, scientific publishing, and information science communities. The organization’s goal is to serve as an authoritative resource on current and emerging issues in the communication of scientific information (1). Similar to other scholarly publishing organizations, CSE continues to facilitate important conversations and training regarding why, how, and where principles of diversity, equity, inclusion, and accessibility (DEIA) should be integrated into scholarly publishing. With guidance from CSE members with expertise in DEIA in scholarly publishing, and the approval of CSE’s Board of Directors, the organization established the DEI Committee in 2021 (which was expanded to the DEIA Committee in 2023). The purpose of the DEIA Committee is “to support the organization in building capacity among its leadership, members, and the profession at large to deliver programmatic activities and training that integrate [DEIA] best practices in science editing, publication management, scholarly publishing and communication, member recruitment, participation, and engagement” (2). | | Since the committee’s inception, CSE has implemented and/or participated in 8 broad-ranging DEIA-related activities: 1) adding new content to CSE’s Recommendations for Promoting Integrity in Scientific Journal Publications (3) related to DEIA best practices in scholarly publishing; 2) completing a DEIA sensitivity review of Scientific Style and Format (4), the CSE style manual, for its upcoming 9th edition, scheduled for publication in 2024; 3) a DEIA-related symposium to update members on CSE’s progress in achieving DEIA-related objectives and activities identified in CSE’s Strategic Plan (2); 4) establishing a DEIA column in Science Editor (5), CSE’s quarterly magazine; 5) implementing an inaugural 1-day DEIA short course to a range of professionals in scholarly publishing; 6) implementing its Ethics Clinic on Diversity, Equity, and Inclusion (6); 7) actively serving as a member organization for the Coalition for Diversity & Inclusion in Scholarly Communications (C4DISC) (3); and 8) establishing CSE’s DEIA Scholarly Resources web page (7). |
Physician perceptions of barriers to infection prevention and control in labor and delivery
Barnes LEA , White KA , Young MR , Ramsey PS , Cochran RL , Perkins KM . Infect Control Hosp Epidemiol 2023 1-8 OBJECTIVE: To learn about the perceptions of healthcare personnel (HCP) on the barriers they encounter when performing infection prevention and control (IPC) practices in labor and delivery to help inform future IPC resources tailored to this setting. DESIGN: Qualitative focus groups. SETTING: Labor and delivery units in acute-care settings. PARTICIPANTS: A convenience sample of labor and delivery HCP attending the Infectious Diseases Society for Obstetrics and Gynecology 2022 Annual Meeting. METHODS: Two focus groups, each lasting 45 minutes, were conducted by a team from the Centers for Disease Control and Prevention. A standardized script facilitated discussion around performing IPC practices during labor and delivery. Coding was performed by 3 reviewers using an immersion-crystallization technique. RESULTS: In total, 18 conference attendees participated in the focus groups: 67% obstetrician-gynecologists, 17% infectious disease physicians, 11% medical students, and 6% an obstetric anesthesiologist. Participants described the difficulty of consistently performing IPC practices in this setting because they often respond to emergencies, are an entry point to the hospital, and frequently encounter bodily fluids. They also described that IPC training and education is not specific to labor and delivery, and personal protective equipment is difficult to locate when needed. Participants observed a lack of standardization of IPC protocols in their setting and felt that healthcare for women and pregnant people is not prioritized on a larger scale and within their hospitals. CONCLUSIONS: This study identified barriers to consistently implementing IPC practices in the labor and delivery setting. These barriers should be addressed through targeted interventions and the development of obstetric-specific IPC resources. |
RTS,S/AS01 malaria vaccine pilot implementation in western Kenya: a qualitative longitudinal study to understand immunisation barriers and optimise uptake
Hoyt J , Okello G , Bange T , Kariuki S , Jalloh MF , Webster J , Hill J . BMC Public Health 2023 23 (1) 2283 BACKGROUND: Malaria is a significant public health threat in sub-Saharan Africa, particularly among children. The RTS,S/AS01 malaria vaccine reduces the risk and severity of malaria in children. RTS,S/AS01 was piloted in three African countries, Ghana, Kenya and Malawi, to assess safety, feasibility and cost-effectiveness in real-world settings. A qualitative longitudinal study was conducted as part of the feasibility assessment. This analysis explores RTS,S/AS01 vaccination barriers and identifies potential motivators among caregivers in three sub-counties in western Kenya. METHODS: A cohort of 63 caregivers with a malaria vaccine eligible child was interviewed at three time points over 24 months. A sub-set of 11 caregivers whose eligible children were either partially or non-vaccinated were selected for this sub-analysis. The 5A Taxonomy for root causes of under-vaccination was used to organise the inductively-coded data into categories (awareness, acceptance, access, affordability, and activation) and identify the factors influencing uptake across caregivers. A trajectory analysis was conducted to understand changes in factors over time within each caregiver experience. Caregiver narratives are used to illustrate how the factors influencing uptake were interrelated and changed over time. RESULTS: Lack of awareness, previous negative experiences with routine childhood immunisations and the burden of getting to the health facility contributed to caregivers initially delaying uptake of the vaccine. Over time concerns about vaccine side effects diminished and anticipated vaccination benefits strongly motivated caregivers to vaccinate their children. Persistent health system barriers (e.g., healthcare provider strikes, vaccine stockouts, negative provider attitudes) meant some children missed the first-dose eligibility window by aging-out. CONCLUSIONS: Caregivers in this study believed the RTS,S/AS01 to be effective and were motivated to have their children vaccinated. Despite these positive perceptions of the malaria vaccine, uptake was substantially hindered by persistent health system constraints. Negative provider attitudes emerged as a powerful deterrent to attending immunisation services and hampered uptake of the vaccine. Strategies that focus on improving interpersonal communication skills among healthcare providers are needed. |

Clin Infect Dis 2023 BACKGROUND: During the 2022-2023 influenza season, the United States experienced the highest influenza-associated pediatric hospitalization rate since 2010-2011. Influenza A/H3N2 infections were predominant. METHODS: We analyzed acute respiratory illness (ARI)-associated emergency department or urgent care (ED/UC) encounters or hospitalizations at three health systems among children and adolescents aged 6 months-17 years who had influenza molecular testing during October 2022-March 2023. We estimated influenza A vaccine effectiveness (VE) using a test-negative approach. The odds of vaccination among influenza-A-positive cases and influenza-negative controls were compared after adjusting for confounders and applying inverse-propensity-to-be-vaccinated weights. We developed overall and age-stratified VE models. RESULTS: Overall, 13,547 of 44,787 (30.2%) eligible ED/UC encounters and 263 of 1,862 (14.1%) hospitalizations were influenza-A-positive cases. Among ED/UC patients, 15.2% of influenza-positive versus 27.1% of influenza-negative patients were vaccinated; VE was 48% (95% confidence interval [CI], 44%-52%) overall, 53% (95% CI, 47%-58%) among children aged 6 months-4 years and 38% (95% CI, 30%-45%) among those aged 9-17 years. Among hospitalizations, 17.5% of influenza-positive versus 33.4% of influenza-negative patients were vaccinated; VE was 40% (95% CI, 6%-61%) overall, 56% (95% CI, 23%-75%) among children ages 6 months-4 years and 46% (95% CI, 2%-70%) among those 5-17 years. CONCLUSIONS: During the 2022-2023 influenza season, vaccination reduced the risk of influenza-associated ED/UC encounters and hospitalizations by almost half (overall VE 40-48%). Influenza vaccination is a critical tool to prevent moderate-to-severe influenza illness in children and adolescents. |
Antibody-mediated suppression regulates the humoral immune response to influenza vaccination in humans
Lu X , Liu F , Tzeng WP , York IA , Tumpey T , Levine MZ . J Infect Dis 2023 BACKGROUND: Pre-existing immunity, including memory B-cells and pre-existing antibodies, can modulate antibody responses to influenza in vivo to antigenically related antigens. We investigated whether pre-existing hemagglutination inhibition (HAI) antibodies targeting the K163 epitope on the hemagglutinin (K163-antibodies) could affect antibody responses following vaccination with A/California/07/2009-like (CA/09) A(H1N1)pdm09 influenza viruses in humans. METHODS: Pre- and post-vaccination sera collected from 300 adults (birth year:1961-1998) in 6 seasons (2010-2016) were analyzed using HAI assays with 2 reverse genetics viruses and A(H1N1) viruses circulated from 1977 to 2018. Antibody adsorption assays were used to verify the pre-existing K163-antibody-mediated suppression effect. RESULTS: Pre-existing K163-antibody titers of ≥80 affected HAI antibody responses following influenza vaccination containing CA/09-like antigens. At high K163-antibody concentrations (HAI antibody titers≥160), all HAI antibody responses were suppressed, while at moderate K163-antibody concentrations (HAI antibody titer=80), only K163-epitope-specific antibody responses were suppressed and novel HAI antibody responses targeting the non-K163-epitope(s) were induced by vaccination. Novel antibodies targeting non-K163 epitope(s) cross-reacted with newly emerging A(H1N1)pdm09 strains with a K163Q mutation, rather than historic 1977-2007 A(H1N1) viruses. CONCLUSION: K163-antibody-mediated suppression shapes antibody responses to A(H1N1)pdm09 vaccination. Understanding how pre-existing antibodies suppress and redirect vaccine-induced antibody responses is of great importance to improve vaccine effectiveness. |

Notes from the field: House-to-house campaign administration of inactivated poliovirus vaccine - Sokoto State, Nigeria, November 2022
Biya O , Manu JI , Forbi JC , Wa Nganda G , Ikwe H , Sule A , Edukugho A , Shehu A , Aliyu N , Barau ND , Wiesen E , Sutter RW . MMWR Morb Mortal Wkly Rep 2023 72 (47) 1290-1291 After the 2015 documentation of global eradication of wild poliovirus type 2,* Sabin type 2 oral poliovirus vaccine (OPV) was withdrawn from routine immunization (RI) in all OPV-using countries in 2016, in a global synchronized switch from trivalent OPV (containing vaccine virus serotypes 1, 2, and 3) to bivalent OPV (containing serotypes 1 and 3), to reduce the rare risks for type 2 vaccine-associated paralytic poliomyelitis. Concurrently, the Global Polio Eradication Initiative (GPEI) recommended that all OPV-using countries introduce ≥1 dose of inactivated poliovirus vaccine (IPV) into RI programs; IPV protects against paralysis caused by all three serotypes but cannot be transmitted from person to person or cause paralysis. Use of OPV, especially in areas with low vaccination coverage, is associated with low risk of emergence of vaccine-derived polioviruses (VDPVs). As susceptible persons in new birth cohorts accumulated after withdrawal of OPV type 2, population immunity against infection with serotype 2 declined (1), facilitating the emergence of circulating VDPV type 2 (cVDPV2). During the previous 7 years, cVDPV2 outbreaks required response supplementary immunization activities (SIAs) with monovalent type 2 OPV (mOPV2); however, if SIAs were not of sufficiently high quality and did not achieve high enough coverage, new emergences of cVDPV2 occurred. |
Progress toward measles elimination - Worldwide, 2000-2022
Minta AA , Ferrari M , Antoni S , Portnoy A , Sbarra A , Lambert B , Hatcher C , Hsu CH , Ho LL , Steulet C , Gacic-Dobo M , Rota PA , Mulders MN , Bose AS , Caro WP , O'Connor P , Crowcroft NS . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1262-1268 Measles is a highly contagious, vaccine-preventable disease that requires high population immunity for transmission to be interrupted. All six World Health Organization regions have committed to eliminating measles; however, no region has achieved and sustained measles elimination. This report describes measles elimination progress during 2000-2022. During 2000-2019, estimated coverage worldwide with the first dose of measles-containing vaccine (MCV) increased from 72% to 86%, then declined to 81% in 2021 during the COVID-19 pandemic, representing the lowest coverage since 2008. In 2022, first-dose MCV coverage increased to 83%. Only one half (72) of 144 countries reporting measles cases achieved the measles surveillance indicator target of two or more discarded cases per 100,000 population in 2022. During 2021-2022, estimated measles cases increased 18%, from 7,802,000 to 9,232,300, and the number of countries experiencing large or disruptive outbreaks increased from 22 to 37. Estimated measles deaths increased 43% during 2021-2022, from 95,000 to 136,200. Nonetheless, an estimated 57 million measles deaths were averted by vaccination during 2000-2022. In 2022, measles vaccination coverage and global surveillance showed some recovery from the COVID-19 pandemic setbacks; however, coverage declined in low-income countries, and globally, years of suboptimal immunization coverage left millions of children unprotected. Urgent reversal of coverage setbacks experienced during the COVID-19 pandemic can be accomplished by renewing efforts to vaccinate all children with 2 MCV doses and strengthening surveillance, thereby preventing outbreaks and accelerating progress toward measles elimination. |

Vaccine 2023 BACKGROUND: Bivalent mRNA vaccines were recommended since September 2022. However, coverage with a recent vaccine dose has been limited, and there are few robust estimates of bivalent VE against symptomatic SARS-CoV-2 infection (COVID-19). We estimated VE of a bivalent mRNA vaccine dose against COVID-19 among eligible U.S. healthcare personnel who had previously received monovalent mRNA vaccine doses. METHODS: We conducted a case-control study in 22 U.S. states, and enrolled healthcare personnel with COVID-19 (case-participants) or without COVID-19 (control-participants) during September 2022-May 2023. Participants were considered eligible for a bivalent mRNA dose if they had received 2-4 monovalent (ancestral-strain) mRNA vaccine doses, and were ≥67 days after the most recent vaccine dose. We estimated VE of a bivalent mRNA dose using conditional logistic regression, accounting for matching by region and four-week calendar period. We adjusted estimates for age group, sex, race and ethnicity, educational level, underlying health conditions, community COVID-19 exposure, prior SARS-CoV-2 infection, and days since the last monovalent mRNA dose. RESULTS: Among 3,647 healthcare personnel, 1,528 were included as case-participants and 2,119 as control-participants. Participants received their last monovalent mRNA dose a median of 404 days previously; 1,234 (33.8%) also received a bivalent mRNA dose a median of 93 days previously. Overall, VE of a bivalent dose was 34.1% (95% CI, 22.6%-43.9%) against COVID-19 and was similar by product, days since last monovalent dose, number of prior doses, age group, and presence of underlying health conditions. However, VE declined from 54.8% (95% CI, 40.7%-65.6%) after 7-59 days to 21.6% (95% CI 5.6%-34.9%) after ≥60 days. CONCLUSIONS: Bivalent mRNA COVID-19 vaccines initially conferred approximately 55% protection against COVID-19 among U.S. healthcare personnel. However, protection waned after two months. These findings indicate moderate initial protection against symptomatic SARS-CoV-2 infection by remaining up-to-date with COVID-19 vaccines. |
The path to eradication of rubella
Reef SE , Icenogle JP , Plotkin SA . Vaccine 2023 41 (50) 7525-7531 Since 1969, rubella and its harmful effect on fetuses infected in utero can be prevented by rubella vaccine, usually given in combination with measles vaccine. The rubella vaccine is highly protective both in children and in adults including women intending to become pregnant. Owing to the use of combined measles and rubella vaccines, congenital rubella infection has been eliminated from the Western Hemisphere and nearly all of Europe. Such combined vaccination is now being applied throughout the world, posing the possibility of eventual rubella eradication. The existence of viruses of animals related to rubella does not appear to be a barrier to eradication of the human virus. However, persistent rubella virus in infants infected in utero and of immunosuppressed patients with granulomas may pose a problem for eradication. Nevertheless, this review posits that eradication of rubella is now feasible if routine vaccination of infants and surveillance for chronic infection are correctly applied. |

J Adolesc Health 2023 PURPOSE: Racial discrimination targeting Asians in the United States has increased sharply since the COVID-19 pandemic. Despite a well-established link with mental/physical health outcomes, little is known about how racial discrimination relates to interpersonal violence, particularly in adolescents. To address this gap in knowledge, we examined cross-sectional and longitudinal (1-year follow-up) associations between racial discrimination and interpersonal violence perpetration and victimization in Asian American adolescents in a large US city. METHODS: Data from Waves 3 (2020) and 4 (2021) of a randomized clinical trial of a school-based violence prevention program were examined. We limited our sample to participants who identified as Asian American (n = 344; 48.3% female; Mean(age) = 14.6 years at Wave 3). RESULTS: At Wave 3, 26.5% of the adolescents reported experiencing some form of racial discrimination, including 18.3% experiencing verbal harassment due to race and 16.0% reporting inequitable treatment due to race. Relative to their nonvictimized counterparts, adolescents who experienced racial discrimination were more likely to report being a victim of bullying and teen dating violence cross-sectionally and being a bullying victim longitudinally. Moreover, those who experienced racial discrimination reported more bullying and teen dating violence perpetration concurrently, as well as more dating violence perpetration 1 year later. DISCUSSION: In the understudied population of Asian American adolescents, we found that experiencing racial discrimination contributes to both interpersonal violence victimization and perpetration. Youth violence prevention could include strategies addressing racial discrimination. |
Sex work-related homicides: Insights from the National Violent Death Reporting System, 2012-2020
Nguyen BL , Fowler KA , Betz CJ , Tsukerman K , Smith SG . J Forensic Sci 2023 Homicide is a prevalent cause of death among sex workers, given their increased risk of violence due to proximity to criminal activities such as drug trade and human trafficking. This study analyzes homicide data from the National Violent Death Reporting System (NVDRS) covering 49 US states, the District of Columbia, and Puerto Rico from 2012 to 2020. Case inclusion criteria included: (1) manner of death of homicide, and (2) sex work-related circumstance. Descriptive analyses examined victim and injury characteristics, suspect information, and circumstances. The study identified 321 sex work-related homicides (54% female, 41% male, 6% transgender). Among female victims, 94% were sex workers, and 54% of their suspects were clients. Money conflicts (23%) and other crimes (30%), most often in progress, commonly precipitated homicides of female victims. Substance use problems were reported in 49% of female victims, with 25% of their suspected perpetrators reportedly using substances in the preceding hours. For male victims, 54% were clients and 9% were sex workers. Suspects in male homicides were primarily sex workers (34%) or individuals engaged in sex work-adjacent criminal activities (36%). Money conflicts (49%), other crimes (47%) most often in progress, and sex trafficking involvement (25%) commonly precipitated homicides with male victims. Transgender sex worker victims were mostly transfeminine (94%) and non-Hispanic black (89%). Money conflicts (78%) most commonly precipitated homicides among transgender sex worker victims. These findings can inform prevention strategies addressing underlying risk factors for persons involved in sex work. |
Round bodies detected by treponema pallidum immunohistochemical stain in two cases of cutaneous syphilitic gummata
Birmingham SW , Saeed L , Thurlow CM , Vilfort K , Pillay A , Rojek NW , Doan LT , Lee BA . Am J Dermatopathol 2023 46 (1) 31-35 Tertiary syphilis may present a diagnostic challenge due to negative nontreponemal serologies in up to 30% of cases and frequent lack of identifiable spirochetes on histopathology or other direct detection tests. We report 2 cases of round bodies staining with Treponema pallidum immunohistochemistry by light microscopy in biopsies from cutaneous syphilitic gummata. In 1 case, the finding was validated 3 times by 2 independent laboratories; in the other case, T. pallidum was detected by polymerase chain reaction in the biopsy sample. Spirochete round bodies have previously been reported in the setting of electron microscopy and fluorography, but to the best of our knowledge, have not been reported by light microscopy in a routine skin biopsy. Although the clinical implications are unclear, this may represent a helpful new paradigm for the diagnosis of tertiary syphilis. |
Measuring training effectiveness of laboratory biosafety program offered at African Center for Integrated Laboratory Training in 22 President's Emergency Plan for AIDS Relief supported countries (2008-2014)
Shrivastava R , Stevens T , Westerman L , Bressler D , van Schalkwyk E , Bressler C , Ugwu K , Mwangi C , Opio JP , Nkodyo J , Mwangi JW , Martin MD , Nesby-O'Dell S . Trop Med Health 2023 51 (1) 65 INTRODUCTION: The African Center for Integrated Laboratory Training (ACILT) in Johannesburg, South Africa offered a laboratory biosafety program to improve laboratory biosafety practices in 22 President's Emergency Plan for AIDS Relief (PEPFAR) supported countries. This manuscript evaluates the transference of newly gained knowledge and skills to the participants' place of employment for HIV and TB diagnostic laboratory programs. It also serves as a follow-on to a previously published manuscript that measured training effectiveness for all courses offered at ACILT. METHODS: ACILT offered 20 Laboratory Biosafety and Infrastructure courses (2008-2014), also referred as biosafety course/course comprising of 14 core laboratory safety elements to 402 participants from 22 countries. In 2015, participants received 22 e-questions divided into four categories: (1) Safety Policies, (2) Management's Engagement, (3) Safety Programs and (4) Assessments of Safety Practices to determine retrospectively the training effectiveness of biosafety practices in their place of employment 6 months before and after attending their course. We used Kirkpatrick model to assess the transference of knowledge, skills and obstructive factors. RESULTS: 20% (81/402) of the participants completed the e-questionnaire. The overall percentage of positive responses indicating implementation of new safety practices increased from 50% to 84%. Improvement occurred in all four categories after attending the course, with the greatest increases in Safety Policies (67-94%) and Safety Programs (43-91%). Creating a safety committee, allocating resources, and establishing a facility safety policy were important drivers for implementing and maintaining laboratory safety practices. In addition, accredited laboratories and countries with national safety regulations or policies had a higher percentage of improvements. The most reported challenges were inadequate funding and lack of management enforcement. CONCLUSIONS: PEPFAR and other partners' investments in training institutions, such as ACILT, were effective in building sustainable country ownership to strengthen biosafety practices and were leveraged to combat zoonotic diseases and COVID-19. Although support continues at the national/regional level, a standardized, coordinated and continent-wide sustainable approach to offer a biosafety program-like ACILT is missing. Continuous offerings of biosafety programs similar to ACILT could contribute to sustainable strengthening of laboratory biosafety, QMS and pandemic preparedness. |
Parental absence as an adverse childhood experience among young adults in sub-Saharan Africa
Annor FB , Amene EW , Zhu L , Stamatakis C , Picchetti V , Matthews S , Miedema SS , Brown C , Thorsen VC , Manuel P , Gilbert LK , Kambona C , Coomer R , Trika J , Kamuingona R , Dube SR , Massetti GM . Child Abuse Negl 2023 106556 BACKGROUND: Parental absence in childhood has been associated with multiple negative consequences, such as depression and anxiety in young adulthood. OBJECTIVE: To assess whether parental absence for six months or more in childhood is associated with poor mental health and substance use in young adulthood and whether parental absence accounts for additional variance beyond those explained by other adverse childhood experiences (ACEs) among youth in sub-Saharan Africa. PARTICIPANTS AND SETTINGS: We used combined Violence Against Children and Youth Survey (VACS) data from Cote d'Ivoire (2018), Lesotho (2018), Kenya (2019), Namibia (2019), and Mozambique (2019). Analyses were restricted to 18-24-year-olds (n(f) = 7699; n(m) = 2482). METHODS: We used logistic regression to examine sex-stratified relationships between parental absence in childhood (defined as biological mother or father being away for six months or more before age 18) and mental health problems and substance use and whether parental absence explained additional variance beyond those explained by other ACEs. RESULTS: In sub-Saharan Africa, parental absence in childhood was common (30.5 % in females and 25.1 % in males), significantly associated with poor mental health and substance use among females and males and accounted for additional variance beyond those explained by conventional ACEs. For example, after controlling for study covariates and other ACEs, females who experienced any parental absence had 1.52 (95 % CI = 1.02-2.26) higher odds of experiencing moderate/serious psychological distress compared with those who did not. CONCLUSION: The observed association between parental absence and poor mental health suggests that this experience has significant adverse consequences and merits consideration as an ACE. |
Guidance on mitigating the risk of transmitting respiratory infections during nebulization by the COPD Foundation Nebulizer Consortium
Biney I , Ari A , Barjaktarevic IZ , Carlin B , Christiani DC , Cochran L , Drummond MB , Johnson K , Kealing D , Kuehl PJ , Li J , Mahler DA , Martinez S , Ohar J , Radonovich L , Sood A , Suggett J , Tal-Singer R , Tashkin D , Yates J , Cambridge L , Dailey PA , Mannino DM , Dhand R . Chest 2023 Nebulizers are commonly employed for inhaled drug delivery. As they deliver medication through aerosol generation, clarification is needed on what constitutes safe aerosol delivery in infectious respiratory disease settings. The coronavirus disease 2019 pandemic highlighted the importance of understanding the safety and potential risks of aerosol-generating procedures. However, evidence supporting the increased risk of disease transmission with nebulized treatments is inconclusive, and inconsistent guidelines and differing opinions have left uncertainty regarding their use. Many clinicians opt for alternative devices, but this practice could negatively impact outcomes, especially for patients who may not derive full treatment benefit from hand-held inhalers. Therefore, it is prudent to develop strategies that can be used during nebulized treatment to minimize the emission of fugitive aerosols, these comprising bioaerosols exhaled by infected individuals and medical aerosols generated by the device that may also be contaminated. This is particularly relevant for patient care in the context of a highly transmissible virus. The COPD Foundation Nebulizer Consortium (CNC) was formed in 2020 to address uncertainties surrounding administration of nebulized medication. The CNC is an international, multidisciplinary collaboration of patient advocates, pulmonary physicians, critical care physicians, respiratory therapists, clinical scientists, and pharmacists from research centers, medical centers, professional societies, industry, and government agencies. The CNC developed this Expert Guidance to inform the safe use of nebulized therapies for patients and providers and to answer key questions surrounding medication delivery with nebulizers during pandemics or when exposure to common respiratory pathogens is anticipated. CNC members reviewed literature and guidelines regarding nebulization and developed two sets of guidance statements: one for the health care setting, and one for the home environment. Future studies need to explore the risk of disease transmission with fugitive aerosols associated with different nebulizer types in real patient-care situations and to evaluate the effectiveness of mitigation strategies. |
Could the National Academy Of Medicine's National Plan For Health Workforce Well-Being work as a framework to improve the well-being of our US clinical veterinary healthcare teams?
Tomasi S , Peterson M , Hale C . J Am Vet Med Assoc 2023 262 (1) 1-6 The authors propose using the National Academy of Medicine's (NAM) National Plan for Health Workforce Well-Being as a framework on which the veterinary profession can re-envision patients and clients being cared for by a veterinary workforce that is thriving, where professionals operate in an environment that fosters their occupational well-being and longevity, strives to improve animal and population health, expands and enhances the care experience, and advances animal health equity. Adapting the NAM's National Plan is intended to inspire collective action to improve the well-being of all veterinary professionals and focuses on changes needed across the profession at the organizational and systemic levels. The Plan focuses on 7 priority areas, many of which would require needed changes to the training and practice business models with input from all interested parties-including clients and the diverse communities our professionals serve. This collective approach and process would inevitably be complex; however, the authors believe that the veterinary profession as a community is ready for the challenge to advance the profession. |
Notes from the field: Surveillance of silicosis using electronic case reporting - California, December 2022-July 2023
Flattery J , Woolsey C , Epstein-Corbin M , Blackley DJ , Harrison RJ , Cummings KJ . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1275-1276 Electronic case reporting (eCR) (1) is a promising rapid reporting mechanism, whereby electronic health records (EHRs) automatically generate and transmit a disease report to jurisdictional public health agencies in real time using previously established criteria. All 50 U.S. states and other jurisdictions are connected to the eCR infrastructure. The Reportable Conditions Knowledge Management System (RCKMS),* a component of the eCR infrastructure, is a real-time decision support service that processes reports according to jurisdictional reporting requirements with criteria defined by Council of State and Territorial Epidemiologists’ position statements (1). Health care organizations automatically generate and send an initial case report to the eCR infrastructure when trigger criteria, such as diagnosis codes or laboratory results, are met within their EHRs. Therefore, for all participating California health care organizations, if a health care encounter involves COVID-19 or mpox, an initial case report is generated and sent to the eCR infrastructure for processing. When there is a match between the initial case report triggered by an EHR, and a reportable condition rule is entered into RCKMS by a jurisdictional public health agency, the initial case report is routed by the eCR infrastructure to the public health agency. Other conditions can be added to public health agency reporting rules. | | Silicosis is a progressive, incurable, fibrotic lung disease caused by inhalation of respirable crystalline silica dust produced in industries such as construction, quarrying, and coal mining (2). A resurgence of silicosis among young workers fabricating engineered stone (quartz) countertops in California and in countries including Australia, Israel, and Spain has focused attention on the need for timely case identification for primary and secondary prevention (2–5). In December 2022, the California Department of Public Health (CDPH) added reporting rules for silicosis to RCKMS, so that any initial case report received by the eCR infrastructure from health care provider EHRs that includes a silicosis diagnosis in the patient’s problem list is sent to CDPH for silicosis surveillance. The purpose of this study was to evaluate the utility of eCR for identifying cases of silicosis in California. This study was reviewed and approved by the California Committee for the Protection of Human Subjects institutional review board.† |
Fatal occupational asthma in cannabis production - Massachusetts, 2022
Weaver VM , Hua JT , Fitzsimmons KM , Laing JR , Farah W , Hart A , Braegger TJ , Reid M , Weissman DN . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1257-1261 Multiple respiratory hazards have been identified in the cannabis cultivation and production industry, in which occupational asthma and work-related exacerbation of preexisting asthma have been reported. An employee working in a Massachusetts cannabis cultivation and processing facility experienced progressively worsening work-associated respiratory symptoms, which culminated in a fatal asthma attack in January 2022. This report represents findings of an Occupational Safety and Health Administration inspection, which included a worksite exposure assessment, coworker and next-of-kin interviews, medical record reviews, and collaboration with the Massachusetts Department of Public Health. Respiratory tract or skin symptoms were reported by four of 10 coworkers with similar job duties. Prevention is best achieved through a multifaceted approach, including controlling asthmagen exposures, such as cannabis dust, providing worker training, and conducting medical monitoring for occupational allergy. Evaluation of workers with new-onset or worsening asthma is essential, along with prompt diagnosis and medical management, which might include cessation of work and workers' compensation when relation to work exposures is identified. It is important to recognize that work in cannabis production is potentially causative. |

QuickStats: Percentage* of children and adolescents aged 4-17 years who practiced yoga during the past 12 months,(†) by sex and age group - National Health Interview Survey,(§) United States, 2022
Reuben C . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1279 In 2022, 12.3% of children and adolescents aged 4–17 years had practiced yoga in the past 12 months. Children and adolescents aged 4–11 years were more likely to have practiced yoga than those aged 12–17 years (14.7% versus 9.2%). The declining percentages with age were found for both males and females: 10.4% versus 5.3% among males, and 19.3% versus 13.3% among females. Males were less likely than females to have practiced yoga in both age groups. |
Increasing access to contraception: Examining barriers and facilitators of long-acting reversible contraception
Kroelinger CD , Pagano HP , DeSisto CL , Estrich C , Romero L , Pliska E , Akbarali S , Velonis A , Cox S . J Womens Health (Larchmt) 2023 33 (1) 52-61 Objective(s): To identify barriers and facilitators related to reimbursement processes, device acquisition costs, stocking, and supply of long-acting reversible contraception (LARC) from 27 jurisdictions (26 states/1 territory) participating in the Increasing Access to Contraception Learning Community from 2016 to 2018. Materials and Methods: A descriptive study using qualitative data collected through 27 semistructured key informant interviews was conducted during the final year of the learning community among all jurisdictional teams. Excerpts were extracted and coded by theme, then summarized as barriers or facilitators using implementation science methods. Results: Most jurisdictions (89%) identified barriers to reimbursement processes, device acquisition, stocking, and supply of LARC devices, and 85% of jurisdictions identified facilitators for these domains. Payment methodology challenges and lack of billing and coding processes were identified as the most common barriers to reimbursement processes. Device acquisition cost challenges and lack of delivery facility protocols for billing were the most common barriers to device acquisition, stocking, and supply of LARC. The most common facilitator of reimbursement processes was expanded payment methodology options, whereas supplemental funding for acquisition costs and protocol development were identified as the most common facilitators of device acquisition, stocking, and supply. Conclusion: Revised payment methodologies and broader health systems changes including additional funding sources and protocols for billing, stocking, and supply were used by learning community jurisdictions to address identified barriers. The learning community framework offers a forum for information exchange, peer-to-peer learning, and sharing of best practices to support jurisdictions in addressing identified barriers and facilitators affecting contraception access. |
Abortion surveillance - United States, 2021
Kortsmit K , Nguyen AT , Mandel MG , Hollier LM , Ramer S , Rodenhizer J , Whiteman MK . MMWR Surveill Summ 2023 72 (9) 1-29 PROBLEM/CONDITION: CDC conducts abortion surveillance to document the number and characteristics of women obtaining legal induced abortions and number of abortion-related deaths in the United States. PERIOD COVERED: 2021. DESCRIPTION OF SYSTEM: Each year, CDC requests abortion data from the central health agencies for the 50 states, the District of Columbia, and New York City. For 2021, a total of 48 reporting areas voluntarily provided aggregate abortion data to CDC. Of these, 47 reporting areas provided data each year during 2012-2021. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2020 were assessed as part of CDC's Pregnancy Mortality Surveillance System (PMSS). RESULTS: A total of 625,978 abortions for 2021 were reported to CDC from 48 reporting areas. Among 47 reporting areas with data each year during 2012-2021, in 2021, a total of 622,108 abortions were reported, the abortion rate was 11.6 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 204 abortions per 1,000 live births. From 2020 to 2021, the total number of abortions increased 5% (from 592,939 total abortions), the abortion rate increased 5% (from 11.1 abortions per 1,000 women aged 15-44 years), and the abortion ratio increased 4% (from 197 abortions per 1,000 live births). From 2012 to 2021, the total number of reported abortions decreased 8% (from 673,634), the abortion rate decreased 11% (from 13.1 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 1% (from 207 abortions per 1,000 live births).In 2021, women in their 20s accounted for more than half of abortions (57.0%). Women aged 20-24 and 25-29 years accounted for the highest percentages of abortions (28.3% and 28.7%, respectively) and had the highest abortion rates (19.7 and 19.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.6%, respectively) and had the lowest abortion rates (0.4 and 2.5 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 30-39 years.From 2020 to 2021, abortion rates increased among women aged 20-39 years, decreased among adolescents aged 15-19 years, and did not change among adolescents aged <15 years and women aged ≥40 years. Abortion rates decreased from 2012 to 2021 among all age groups, except women aged 30-34 years for whom it increased. The decrease in the abortion rate from 2012 to 2021 was highest among adolescents compared with any other age group. From 2020 to 2021, abortion ratios increased for women aged 15-24 years, decreased among adolescents aged <15 years and women aged ≥35 years and did not change for women aged 25-34 years. From 2012 to 2021, abortion ratios increased among women aged 15-29 years and decreased among adolescents aged <15 years and women aged ≥30 years. The decrease in abortion ratio from 2012 to 2021 was highest among women aged ≥40 years compared with any other age group.In 2021, the majority (80.8%) of abortions were performed at ≤9 weeks' gestation, and nearly all (93.5%) were performed at ≤13 weeks' gestation. During 2012-2021, the percentage of abortions performed at >13 weeks' gestation remained ≤8.7%. In 2021, the highest percentage of abortions were performed by early medication abortion at ≤9 weeks' gestation (53.0%), followed by surgical abortion at ≤13 weeks' gestation (37.6%), surgical abortion at >13 weeks' gestation (6.4%), and medication abortion at >9 weeks' gestation (3.0%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks' gestation), 66.6% of abortions were early medication abortions. In 2020, the most recent year for which PMSS data were reviewed for pregnancy-related deaths; six women died as a result of complications from legal induced abortion. INTERPRETATION: Among the 47 areas that reported data continuously during 2012-2021, overall decreases were observed during 2012-2021 in the total number, rate, and ratio of reported abortions; however, from 2020 to 2021, increases were observed across all measures. PUBLIC HEALTH ACTION: Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies. |
State-specific prevalence of adult tobacco product use and cigarette smoking cessation behaviors, United States, 2018-2019
Cornelius ME , Wang TW , Jamal A , Loretan CG , Willis G , Graham-Glover B , Neff L . Prev Chronic Dis 2023 20 E107 INTRODUCTION: Increasing quitting among people who smoke cigarettes is the quickest approach to reducing tobacco-related disease and death. METHODS: We analyzed data from the 2018-2019 Tobacco Use Supplement to the Current Population Survey for 137,471 adult self-respondents from all 50 US states and the District of Columbia to estimate state-specific prevalence of current tobacco product use, interest in quitting smoking, past-year quit attempts, recent successful cessation (past-year quit lasting ≥6 months), receipt of advice to quit smoking from a medical doctor, and use of cessation medications and/or counseling to quit. RESULTS: Prevalence of current any-tobacco use (use every day or some days) ranged from 10.2% in California to 29.0% in West Virginia. The percentage of adults who currently smoked cigarettes and were interested in quitting ranged from 68.2% in Alabama to 87.5% in Connecticut; made a past-year quit attempt ranged from 44.1% in Tennessee to 62.8% in Rhode Island; reported recent successful cessation ranged from 4.6% in West Virginia and Wisconsin to 10.8% in South Dakota; received advice to quit from a medical doctor ranged from 63.3% in Colorado to 86.9% in Rhode Island; and used medications and/or counseling to quit ranged from 25.5% in Nevada to 50.1% in Massachusetts. Several states with the highest cigarette smoking prevalence reported the lowest prevalence of interest in quitting, quit attempts, receipt of advice to quit, and use of counseling and/or medication, and the highest prevalence of e-cigarette, smokeless tobacco, and cigar use. CONCLUSION: Adults who smoke struggle with smoking cessation and could benefit from additional intervention. |
Systematic review and meta-analysis of the relationship between exposure to parental substance use and attention-deficit/hyperactivity disorder in children
Maher BS , Bitsko RH , Claussen AH , O'Masta B , Cerles A , Holbrook JR , Mahmooth Z , Chen-Bowers N , Rojo ALA , Kaminski JW , Rush M . Prev Sci 2023 Attention-deficit/hyperactivity disorder (ADHD) is characterized by persistent patterns of inattention, hyperactivity, and impulsiveness. Among US children and adolescents aged 3-17 years, 9.4% have a diagnosis of ADHD. Previous research suggests possible links between parental substance use and ADHD among children. We conducted a systematic review and meta-analysis of 86 longitudinal or retrospective studies of prenatal or postnatal alcohol, tobacco, or other parental substance use and substance use disorders and childhood ADHD and its related behavioral dimensions of inattention and hyperactivity-impulsivity. Meta-analyses were grouped by drug class and pre- and postnatal periods with combined sample sizes ranging from 789 to 135,732. Prenatal exposure to alcohol or tobacco and parent substance use disorders were consistently and significantly associated with ADHD among children. Other parental drug use exposures resulted in inconsistent or non-significant findings. Prevention and treatment of parental substance use may have potential for impacts on childhood ADHD. |
QuickStats: Percentage* of adults aged ≥18 years who rarely or never get the social and emotional support they need,(†) by sex and disability status(§) - National Health Interview Survey,(¶) United States, 2021
Arockiaraj B , Ng AE . MMWR Morb Mortal Wkly Rep 2023 72 (47) 1292 In 2021, 6.9% of adults aged ≥18 years rarely or never got the social and emotional support they needed. Overall, the percentage was higher among those with a disability (11.7%) than among those without disability (6.4%). Among men, 11.3% of those with disability rarely or never got needed support, compared with 7.0% of those without disability. Among women, 12.1% of those with disability rarely or never got needed support, compared with 5.9% of those without disability. The percentage of women and men with disability who rarely or never got the support needed was similar but was higher for men compared with women among those without disability. |
