Substance use and help seeking as coping behaviors among parents and unpaid caregivers of adults in the United States during the COVID-19 pandemic
Varma P , DePadilla L , Czeisler MÉ , Rohan EA , Weaver MD , Quan SF , Robbins R , Patel CG , Melillo S , Drane A , Winnay SS , Lane RI , Czeisler CA , Howard ME , Rajaratnam SMW , Matjasko JL . Am J Drug Alcohol Abuse 2024 1-13 Background: During the COVID-19 pandemic, caregiving responsibilities may have been associated with increased substance use.Objectives: To characterize substance use to cope with stress and willingness to seek help among (i) parents, (ii) unpaid caregivers of adults, and (iii) parent-caregivers.Methods: Data were analyzed for 10,444 non-probabilistic internet-based survey respondents of the COVID-19 Outbreak Public Evaluation (COPE) initiative (5227 females, 5217 males). Questions included new or increased substance use, substance use in the past 30 days to cope, insomnia, mental health, and willingness to seek help.Results: Nearly 20% of parents and unpaid caregivers of adults each reported new or increased use of substances to cope with stress or emotions; 65.4% of parent-caregivers endorsed this response. Compared to non-caregivers, all caregiver groups had higher odds of new or increased use of substances, with parent-caregivers showing the largest effect size (aOR: 7.19 (5.87-8.83), p < .001). Parent-caregivers had four times the adjusted odds of using drugs other than cannabis (aOR: 4.01 (3.15-5.09), p < .001) compared to non-caregivers.Conclusions: Caregivers may initiate or increase substance use as a coping strategy when under stress. The higher odds of substance use underscores the importance of efforts to screen for sleep disturbances and adverse mental health symptoms, particularly among parent-caregivers. Clinicians may consider asking patients about family situations more broadly to help identify people who may be experiencing stress related to caregiving and, if indicated, offer treatment to potentially alleviate some of the risks. |
Changes in self-reported mask use after the lifting of state-issued mask mandates in 20 US States, February-June 2021
Ajiboye AS , Dunphy C , Vo L , Howard-Williams M , Ladva CN , Robinson SJ , McCord R , Gakh M , Weber R , Sunshine G . J Public Health Manag Pract 2024 OBJECTIVE: In April 2020, the US Centers for Disease Control and Prevention (CDC) recommended community masking to prevent the transmission of SARS-CoV-2. Since then, a total of 39 US states and DC issued mask mandates. Despite CDC recommendations and supporting evidence that masking reduces COVID-19 community transmission, from January to June 20, 2021 states lifted their mask mandates for all individuals. This study examined the association between lifting state-issued mask mandates and mask-wearing behavior in 2021. DESIGN: We estimated a difference-in-difference model, comparing changes in the likelihood for individuals to wear a mask in states that lifted their mask mandate relative to states that kept their mandates in place between February and June of 2021. SETTING: Individuals were surveyed from across the United States. PARTICIPANTS: We used masking behavior data collected by the Porter Novelli View 360 + national surveys (N = 3459), and data from state-issued mask mandates obtained by CDC and the University of Nevada, Las Vegas. MAIN OUTCOMES: The outcome variable of interest was self-reported mask use during the 30 days prior to the survey data collection. RESULTS: In the overall population, lifting mask mandates did not significantly influence mask-wearing behavior. Mask wearing did significantly decrease in response to the lifting of mask mandates among individuals living in rural counties and individuals who had not yet decided whether they would receive a COVID-19 vaccine. CONCLUSION: Policies around COVID-19 behavioral mitigation, specifically amongst those unsure about vaccination and in rural areas, may help reduce the transmission of COVID-19 and other respiratory viruses, especially in communities with low vaccination rates. |
Managing workplace AI risks and the future of work
Howard J , Schulte P . Am J Ind Med 2024 Artificial intelligence (AI)-the field of computer science that designs machines to perform tasks that typically require human intelligence-has seen rapid advances in the development of foundation systems such as large language models. In the workplace, the adoption of AI technologies can result in a broad range of hazards and risks to workers, as illustrated by the recent growth in industrial robotics and algorithmic management. Sources of risk from deployment of AI technologies across society and in the workplace have led to numerous government and private sector guidelines that propose principles governing the design and use of trustworthy and ethical AI. As AI capabilities become integrated in devices, machines, and systems across industry sectors, employers, workers, and occupational safety and health practitioners will be challenged to manage AI risks to worker health, safety, and well-being. Five risk management options are presented as ways to assure that only trustworthy and ethical AI enables workplace devices, machinery, and processes. AI technologies will play a significant role in the future of work. The occupational safety and health practice and research communities need to ensure that the promise of these new AI technologies results in benefit, not harm, to workers. |

Convenience sampling yields no evidence of SARS-CoV-2 infection in free-ranging mammalian wildlife in Arizona, USA, 2021-23
Yaglom HD , Van Pelt L , Howard AL , Jansen B , Smith P , Sorensen R , Hecht G , Venkat H , Justice-Allen A , Bergman DL , Engelthaler DM . J Wildl Dis 2023 Susceptibility of free-ranging US wildlife to SARS-CoV-2 infection has been documented. Nasal or oral swabs and blood from 337 wild mammals (31 species) in Arizona USA, tested for antibodies and by reverse-transcription PCR, did not reveal evidence of SARS-CoV-2. Broader surveillance efforts are necessary to understand the role of wildlife. |
Guidelines for tuberculosis screening and preventive treatment among pregnant and breastfeeding women living with HIV in PEPFAR-supported countries
Hirsch-Moverman Y , Hsu A , Abrams EJ , Killam WP , Moore B , Howard AA . PLoS One 2024 19 (4) e0296993 BACKGROUND: Tuberculosis (TB) preventive treatment (TPT) is recommended by the World Health Organization (WHO) for persons living with HIV, including pregnant and breastfeeding women. Given the President's Emergency Plan for AIDS Relief (PEPFAR)'s investment in TPT services for persons living with HIV as a strategy to prevent TB as well as uncertainty in guidelines and policy regarding use of TPT during pregnancy and the postpartum period, we conducted a review of current relevant national guidelines among PEPFAR-supported countries. METHODS: Our review included 44/49 PEPFAR-supported countries to determine if TB screening and TPT are recommended specifically for pregnant and breastfeeding women living with HIV (WLHIV). National guidelines reviewed and abstracted included TB, HIV, prevention of vertical HIV transmission, TPT, and any other relevant guidelines. We abstracted information regarding TB screening, including screening tools and frequency; and TPT, including timing, regimen, frequency, and laboratory monitoring. RESULTS: Of 44 PEPFAR-supported countries for which guidelines were reviewed, 66% were high TB incidence countries; 41% were classified by WHO as high TB burden countries, and 43% as high HIV-associated TB burden countries. We found that 64% (n = 28) of countries included TB screening recommendations for pregnant WLHIV in their national guidelines, and most (n = 35, 80%) countries recommend TPT for pregnant WLHIV. Fewer countries included recommendations for breastfeeding as compared to pregnant WLHIV, with only 32% (n = 14) mentioning TB screening and 45% (n = 20) specifically recommending TPT for this population; most of these recommend isoniazid-based TPT regimens for pregnant and breastfeeding WLHIV. However, several countries also recommend isoniazid combined with rifampicin (3RH) or rifapentine (3HP). CONCLUSIONS: Despite progress in the number of PEPFAR-supported countries that specifically include TB screening and TPT recommendations for pregnant and breastfeeding WLHIV in their national guidelines, many PEPFAR-supported countries still do not include specific screening and TPT recommendations for pregnant and breastfeeding WLHIV. |
Patterns of care for Medicare beneficiaries with metastatic prostate cancer
Filson CP , Richards TB , Ekwueme DU , Howard DH . Urol Pract 2024 11 (3) 489-497 INTRODUCTION: Therapeutic options for men with metastatic prostate cancer have increased in the past decade. We studied recent treatment patterns for men with metastatic prostate cancer and how treatment patterns have changed over time. METHODS: Using the Surveillance, Epidemiology, and End Results‒Medicare database, we identified fee-for-service Medicare beneficiaries who either were diagnosed with metastatic prostate cancer or developed metastases following diagnosis, as indicated by the presence of claims with diagnoses codes for metastatic disease, between 2007 and 2017. We evaluated treatment patterns using claims. RESULTS: We identified 29,800 men with metastatic disease, of whom 4721 (18.8%) had metastatic disease at their initial diagnosis. The mean age was 77 years, and 77.9% of patients were non-Hispanic White. The proportion receiving antineoplastic agents within 3 years of the index date increased over time (from 9.7% in 2007 to 25.9% in 2017; P < .001). Opioid use within 3 years of prostate cancer diagnosis was stable during 2007 to 2013 (around 73%) but decreased through 2017 to 65.5% (P < .001). Patients diagnosed during 2015 to 2017 had longer median survival (32.6 months) compared to those diagnosed during 2007 to 2010 (26.6 months; P < .001). CONCLUSIONS: Most metastatic prostate cancer patients do not receive life-prolonging antineoplastic therapies. Improved adoption of effective cancer therapies when appropriate may increase length and quality of survival among metastatic prostate cancer patients. |
Health belief model to assess Mpox knowledge, attitudes, and practices among residents and staff, cook county jail, Illinois, USA, July-August 2022
Hassan R , Meehan AA , Hughes S , Beeson A , Spencer H , Howard J , Tietje L , Richardson M , Schultz A , Zawitz C , Ghinai I , Hagan LM . Emerg Infect Dis 2024 30 (13) S49-s55 In summer 2022, a case of mpox was confirmed in a resident at the Cook County Jail (CCJ) in Chicago, Illinois, USA. We conducted in-depth interviews with CCJ residents and staff to assess mpox knowledge, attitudes, and practices; hygiene and cleaning practices; and risk behaviors. We characterized findings by using health belief model constructs. CCJ residents and staff perceived increased mpox susceptibility but were unsure about infection severity; they were motivated to protect themselves but reported limited mpox knowledge as a barrier and desired clear communication to inform preventive actions. Residents expressed low self-efficacy to protect themselves because of contextual factors, including perceived limited access to cleaning, disinfecting, and hygiene items. Our findings suggest correctional facilities can support disease prevention by providing actionable and tailored messages; educating residents and staff about risk and vaccination options; and ensuring access to and training for hygiene, cleaning, and disinfecting supplies. |
An urgent call to address work-related psychosocial hazards and improve worker well-being
Schulte PA , Sauter SL , Pandalai SP , Tiesman HM , Chosewood LC , Cunningham TR , Wurzelbacher SJ , Pana-Cryan R , Swanson NG , Chang CC , Nigam JAS , Reissman DB , Ray TK , Howard J . Am J Ind Med 2024 Work-related psychosocial hazards are on the verge of surpassing many other occupational hazards in their contribution to ill-health, injury, disability, direct and indirect costs, and impact on business and national productivity. The risks associated with exposure to psychosocial hazards at work are compounded by the increasing background prevalence of mental health disorders in the working-age population. The extensive and cumulative impacts of these exposures represent an alarming public health problem that merits immediate, increased attention. In this paper, we review the linkage between work-related psychosocial hazards and adverse effects, their economic burden, and interventions to prevent and control these hazards. We identify six crucial societal actions: (1) increase awareness of this critical issue through a comprehensive public campaign; (2) increase etiologic, intervention, and implementation research; (3) initiate or augment surveillance efforts; (4) increase translation of research findings into guidance for employers and workers; (5) increase the number and diversity of professionals skilled in preventing and addressing psychosocial hazards; and (6) develop a national regulatory or consensus standard to prevent and control work-related psychosocial hazards. |

Caregiver perspectives on barriers and facilitators to timely well-child visits for black infants
Dever R , Wong CA , Franklin MS , Howard J , Cholera R . Matern Child Health J 2024 OBJECTIVES: Missed infant well-child visits (WCV) result in lost opportunities for critical preventive care. Black infants consistently receive less WCV care than other racial groups. We sought to understand barriers and facilitators to timely infant WCV for Black families in the context of COVID-19. METHODS: We conducted 21 semi-structured interviews with caregivers of Medicaid-insured Black children aged 15- to 24-months who attended six or fewer of eight recommended well-child visits within the first 15 months of life. Interviews focused on WCV value, barriers, and facilitators. After developing our initial coding structure through rapid qualitative analysis, we inductively derived the final codebook and themes through line-by-line content analysis. RESULTS: Caregivers attended a mean of 3.53 of eight infant visits. Structural (e.g., transportation) and psychological (e.g., maternal depression) barriers delayed Black infant WCV. Families most frequently valued monitoring development and addressing concerns. Caregivers perceived visits as less urgent when infants seemed healthy or more recently avoided visits due to fears around COVID-19. Long waits and feeling rushed/dismissed were linked to WCV delays; positive provider relationships encouraged WCV attendance. Most caregivers reported reluctance to vaccinate. Vaccine hesitancy contributed to delayed infant WCV. CONCLUSIONS: Caregivers described several factors that impacted WCV attendance for Black infants. Persistent structural and psychological barriers are compounded by perceptions that caregiver time is not respected and by notable vaccine hesitancy. To address these barriers, well-care can meet Black families in their communities, better address caregiver wellbeing, more efficiently use caregiver and provider time, and cultivate partnerships with Black caregivers. |

Long COVID and occupational medicine practice
Howard J , Cloeren M , Vanichkachorn G . J Occup Environ Med 2024 66 (1) 1-5 The national public health emergency declared in response to the worldwide pandemic of “coronavirus disease 2019” or COVID-19 ended on May 11, 2023, in the United States.1 Whereas most Americans infected with the causative agent of COVID-19—the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)—recover their usual state of health, others experience a broad array of new or continuing debilitating symptoms. Grouped together, these various post–COVID-19 symptoms are collectively known by the patient-generated term, “long COVID; by the term, “postacute sequelae of SARS-CoV-2 infection2; or by the World Health Organization's term, “post–COVID-19 condition.”3,4 In this editorial, the term “long COVID” will be used. | | Although a single case definition has not been widely accepted, the World Health Organization has defined long COVID as “the continuation or development of new symptoms 3 months after the initial SARS-CoV-2 infection, with these symptoms lasting for at least 2 months with no other explanation.”5 The US Department of Health and Human Services emphasizes that “long COVID is not one condition. It represents many potentially overlapping entities, likely with different biological causes and different sets of risk factors and outcomes.”6 |
Health-related quality of life among prostate cancer survivors with metastatic disease and non-metastatic disease and men without a cancer history in the USA
Zheng Z , Shi KS , Kamal A , Howard DH , Horný M , Richards TB , Ekwueme DU , Yabroff KR . J Cancer Surviv 2023 BACKGROUND: Few studies have comprehensively compared health-related quality of life (HRQoL) between metastatic prostate cancer survivors, survivors with non-metastatic disease, and men without a cancer history. METHODS: We used the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) data linkage to identify men aged ≥ 65 years enrolled in Medicare Advantage (MA) plans. Prostate cancer survivors were diagnosed between 1988 and 2017 and completed MHOS surveys between 1998 and 2019. We analyzed data from 752 metastatic prostate cancer survivors (1040 survey records), 19,583 localized or regional prostate cancer survivors (non-metastatic; 30,121 survey records), and 784,305 men aged ≥ 65 years without a cancer history in the same SEER regions (1.15 million survey records). We used clustered linear regressions to compare HRQoL measures at the person-level using the Veterans RAND 12 Item Health Survey (VR-12) T-scores for general health and physical and mental component summaries. RESULTS: Compared to men without a cancer history, prostate cancer survivors were older, more likely to be married, and had higher socioeconomic status. Compared to men without a cancer history, metastatic prostate cancer survivors reported lower general health (T-score differences [95% confidence interval]: - 6.26, [- 7.14, - 5.38], p < .001), physical health (- 4.33, [- 5.18, - 3.48], p < .001), and mental health (- 2.64, [- 3.40, - 1.88], p < .001) component summaries. Results were similar for other VR-12 T-scores. In contrast, non-metastatic prostate cancer survivors reported similar VR-12 T-scores as men without a cancer history. Further analyses comparing metastatic and non-metastatic prostate cancer survivors support these findings. CONCLUSION: Interventions to improve health-related quality of life for men diagnosed with metastatic prostate cancer merit additional investigation. IMPLICATIONS FOR CANCER SURVIVORS: Interventions to improve health-related quality of life for metastatic prostate cancer survivors merit additional investigation. |
Notes from the field: Responding to the wartime spread of antimicrobial-resistant organisms - Ukraine, 2022
Kuzin I , Matskov O , Bondar R , Lapin R , Vovk T , Howard A , Vodianyk A , Skov R , Legare S , Azarskova M , Al-Samarrai T , Barzilay E , Vitek C . MMWR Morb Mortal Wkly Rep 2023 72 (49) 1333-1334 Worldwide, bacterial antimicrobial resistance is estimated to cause more deaths than HIV or malaria and is recognized as a leading global public health threat (1). In Ukraine, the confluence of high prewar rates of antimicrobial resistance, an increase in the prevalence of traumatic wounds, and the war-related strain on health care facilities is leading to increased detection of multidrug-resistant organisms with spread into Europe (2,3). Evidence of increased rates of antimicrobial resistance in other conflict settings such as Iraq (4), and the long-term consequences for civilian, military, and other populations, argue that the spread of antimicrobial resistance in Ukraine is an urgent crisis that must be addressed, even during an ongoing war. | | In mid-2022, a collaboration was established between CDC, the Center for Public Health of Ukraine (UPHC), local clinical and public health authorities, and international partners, including the World Health Organization regional office for Europe, ICAP at Columbia University, and the European Society for Clinical Microbiology and Infectious Diseases. The purpose of this collaboration was to improve laboratory detection, clinical treatment, and infection control response for antimicrobial resistance in the Ternopil, Khmelnytskyi, and Vinnytsia regions supported by U.S. Ukraine supplemental appropriations emergency funding.* |

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. |
Preparing the occupational safety and health workforce for future disruptions
Streit JMK , Felknor SA , Edwards NT , Caruso DL , Howard J . Am J Ind Med 2023 67 (1) 55-72 BACKGROUND: Despite some emerging lessons learned from the COVID-19 pandemic, evidence suggests the world remains largely underprepared for-and vulnerable to-similar threats in the future. METHODS: In 2022, researchers at the US National Institute for Occupational Safety and Health (NIOSH) led a team of volunteers to explore how future disruptions, such as pandemics, might impact work and the practice of occupational safety and health (OSH). This qualitative inquiry was framed as a strategic foresight project and included a series of activities designed to help better understand, prepare for, and influence the future. RESULTS: Findings from a thorough search for indicators of change were synthesized into nine critical uncertainties and four plausible future scenarios. Analysis of these outputs elucidated three key challenges that may impact OSH research, policy, and practice during future disruptions: (1) data access, (2) direct-to-worker communications, and (3) mis- and dis-information management. CONCLUSIONS: A robust strategic response is offered to address these challenges, and next steps are proposed to enhance OSH preparedness and institutionalize strategic foresight across the OSH community. |
Monitoring workers' health: focus on rights, determinants, and equity
Pega F , Momen NC , Abubakar AHA , Al-Emam R , Hassan MN , Howard J , Hussein SH , Iavicoli S , Kevi SK , Kgalamono SM , Malik SMR , K GM , Osman AY , Pandav RS , Shrestha RRP , Singh DR , Sun X , Wotobe MK , Neira MP . Lancet 2023 402 (10410) 1306-1308 The Lancet Series on Work and Health1, 2, 3 recognises that changes in the world of work are causing new occupational hazards to physical and mental health and increasing health inequalities within and between countries. These changes have profound implications for official workers’ health data and monitoring systems, which have become a global health priority as the world seeks to reach the Sustainable Development Goals (SDGs).4, 5 These monitoring systems are public goods that provide international organisations, governments, and communities the evidence base for policy and practice that ensures health for all workers. We argue that these monitoring systems must respond to changing working environments by expanding capture of workers’ rights, working conditions, and health inequalities. We outline normative data and monitoring products to reach this systemic shift and provide the public health vision for this new direction. | | No worker should die or get ill because of their work, or be left behind in occupational health protection and promotion. All workers are entitled to the human rights to: health;6 a clean, healthy, and sustainable environment; and a safe and healthy working environment.7 However, WHO and the International Labour Organization (ILO) estimate that annually 2 million deaths and 90 million disability-adjusted life-years are attributable to selected occupational risk factors.8 Recognition is growing that improving workers’ health and health equity requires action on the social and environmental determinants of health. Examples include strengthened evidence on the effects of the emerging psychosocial hazard of long working hours on cardiovascular disease,9 and the environmental and climate crises strengthening attention to workers’ environmental and climatic hazards (eg, air pollution and heat exposures). Occupational health policy increasingly comprises health equity analysis and targets. The WHO/ILO joint estimates show geographical and socioeconomic health inequalities—an increased number of deaths is noted among workers in Africa, South-East Asia, and the Western Pacific, and among men and people aged 55 years or older.8 People working in the informal economy, and migrant, outdoor, and front-line workers are often especially disadvantaged. Health-care workers, despite working in a sector that aims to restore, protect, and promote health, often face hazardous working conditions and are exposed to pathogens (eg, SARS-CoV-2), violence, and long working hours, among others. Ongoing changes in working environments (eg, globalisation, automation, digitisation, new pandemics, environmental pollution, and climate change) exacerbate these inequalities. Ultimately, unhealthy working conditions act as barriers for realising workers’ rights to health, population health, and health equity, and threaten the goal of achieving the SDGs globally. |
Shiftwork, long working hours and markers of inflammation in a national US population-based sample of employed black and white men and women aged ≥45 years
Velazquez-Kronen R , MacDonald LA , Akinyemiju TF , Cushman M , Howard VJ . Occup Environ Med 2023 80 (11) 635-643 OBJECTIVES: Work schedule demands contribute to circadian disruption and may influence health via an inflammatory response. We examined the impact of shiftwork and long work hours on inflammation in a national US sample. METHODS: Participants included 12 487 employed black and white men and women aged ≥45 years enrolled in the REasons for Geographic and Racial Differences in Stroke Study who completed an occupational questionnaire (2011-2013) and clinical examination (2013-2016). Cross-sectional associations between shiftwork and work hours with log-transformed high-sensitivity C reactive protein (CRP) and white blood cell (WBC) count were examined by multiple linear regression analysis, overall and by race-sex subgroups. RESULTS: Overall, rotating shift workers had higher log-CRP concentration compared with day workers (β=0.09, 95% CI:0.02 to 0.16) and findings for WBC were null. Black women had the highest geometric mean CRP (2.82 mg/L), while white men had the highest WBC (6.35×10(9)/L). White men who worked afternoons had higher log-CRP compared with those who worked days (β=0.20, 95% CI: 0.08 to 0.33). Black men engaged in shiftwork <10 years working ≥55 hours/week had higher log-CRP and log-WBC compared with those working days <55 hours/week (β=0.33, 95% CI: 0.02 to 0.64 and β=0.10, 95% CI: 0.003 to 0.19). Among shift workers, non-retired white women working forward and backward shift rotations had higher log-CRP compared with those working forward only (β=0.49, 95% CI: 0.02 to 0.96). CONCLUSIONS: Shift workers had higher inflammatory markers compared with day workers and race-sex disparities should be examined further. These findings highlight a potential biological pathway linking work schedule demands and chronic disease. |
U. S. federal perspective on critical research issues in nanoEHS
Carter J , Bjorkland R , Boyes WK , Geraci C , Hackley VA , Howard J , Kennedy A , Linkov I , Matheson J , Mortensen H , Muianga C , Petersen EJ , Savage N , Schulte P , Standridge S , Thomas T , Trump B , Nadadur S . Environ Sci Nano 2023 This article discusses critical issues and opportunities going forward in nanotechnology environmental, health, and safety (nanoEHS) research from the perspective of Federal Government Agency participants in the United States (U.S.) National Nanotechnology Initiative (NNI) interagency Nanotechnology Environmental and Health Implications Working Group (NEHI). NEHI is responsible for coordination of Federal Science Agency nanoEHS research. As participants in NEHI, we examine these critical issues from an integrated, transdisciplinary perspective, noting examples of impactful research efforts that are advancing knowledge in these areas. Major themes identified include detection, measurement, and characterization of real-world nanomaterial exposures, understanding the biological transformation of nanomaterials and their potential (eco) toxicological implications, understanding the landscape of nanotechnology-enabled products in commerce, and advancing the EHS knowledge infrastructure related to nanomaterials and nanotechnology. Significant investments in nanoEHS research over two decades have led to establishment of a unique and diverse multidisciplinary, multisector community of practice. These investments must be leveraged and adapted not only to future nanotechnology, but also to use as a model for accelerating acquisition of safe and reliable risk information for tomorrow's emerging technologies for a more sustainable and competitive world. © 2023 The Royal Society of Chemistry. |

Popul Health Metr 2023 21 (1) 10 INTRODUCTION: Infant and neonatal mortality estimates are typically derived from retrospective birth histories collected through surveys in countries with unreliable civil registration and vital statistics systems. Yet such data are subject to biases, including under-reporting of deaths and age misreporting, which impact mortality estimates. Prospective population-based cohort studies are an underutilized data source for mortality estimation that may offer strengths that avoid biases. METHODS: We conducted a secondary analysis of data from the Child Health Epidemiology Reference Group, including 11 population-based pregnancy or birth cohort studies, to evaluate the appropriateness of vital event data for mortality estimation. Analyses were descriptive, summarizing study designs, populations, protocols, and internal checks to assess their impact on data quality. We calculated infant and neonatal morality rates and compared patterns with Demographic and Health Survey (DHS) data. RESULTS: Studies yielded 71,760 pregnant women and 85,095 live births. Specific field protocols, especially pregnancy enrollment, limited exclusion criteria, and frequent follow-up visits after delivery, led to higher birth outcome ascertainment and fewer missing deaths. Most studies had low follow-up loss in pregnancy and the first month with little evidence of date heaping. Among studies in Asia and Latin America, neonatal mortality rates (NMR) were similar to DHS, while several studies in Sub-Saharan Africa had lower NMRs than DHS. Infant mortality varied by study and region between sources. CONCLUSIONS: Prospective, population-based cohort studies following rigorous protocols can yield high-quality vital event data to improve characterization of detailed mortality patterns of infants in low- and middle-income countries, especially in the early neonatal period where mortality risk is highest and changes rapidly. |
Clinical and genomic epidemiology of mcr-9-carrying carbapenem-resistant Enterobacterales isolates in Metropolitan Atlanta, 2012-2017 (preprint)
Babiker A , Bower C , Lutgring JD , Howard-Anderson J , Ansari U , McAllister G , Adamczyk M , Breaker E , Satola SW , Jacob JT , Woodworth MH . medRxiv 2021 2021.10.13.21264308 Colistin is a last-resort antibiotic for multidrug-resistant gram-negative infections. Recently, the ninth allele of the mobile colistin resistance (mcr) gene family, designated mcr-9, was reported. However, its clinical and public health significance remains unclear. We queried genomes of carbapenem-resistant Enterobacterales (CRE) for mcr-9 from a convenience sample of clinical isolates collected between 2012-2017 through the Georgia Emerging Infections Program, a population- and laboratory-based surveillance program. Isolates underwent phenotypic characterization and whole genome sequencing. Phenotypic characteristics, genomic features, and clinical outcomes of mcr-9 positive and negative CRE cases were then compared. Among 235 sequenced CRE genomes, thirteen (6%) were found to harbor mcr-9, all of which were Enterobacter cloacae complex. The median MIC, rates of heteroresistance and inducible resistance to colistin were similar between mcr-9 positive and negative isolates. However, rates of resistance were higher among mcr-9 positive isolates across most antibiotic classes. All cases had significant healthcare exposures. The 90-day mortality was similarly high in both mcr-9 positive (31%) and negative (7%) CRE cases. Nucleotide identity and phylogenetic analysis did not reveal geo-temporal clustering. mcr-9 positive isolates had a significantly higher number of median [range] AMR genes (16 [4-22] vs. 6 [2-15]; p <0.001) compared to mcr-9 negative isolates. Pan genome tests confirmed a significant association of mcr-9 detection with mobile genetic element and heavy metal resistance genes. Overall, the presence of mcr-9 was not associated with significant changes in colistin resistance or clinical outcomes but continued genomic surveillance to monitor for emergence of AMR genes is warranted.Competing Interest StatementThe authors have declared no competing interest.Funding StatementEIP Surveillance of the Multi-site Gram-Negative Surveillance Initiative (MuGSI) was funded through the Centers for Disease Control and Preventions Emerging Infections Program [U50CK000485].Author DeclarationsI confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.YesThe details of the IRB/oversight body that provided approval or exemption for the research described are given below:Georgia EIP surveillance activities are reviewed and approved by the Emory University Institutional Review Board.I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

Immunofocusing humoral immunity potentiates the functional efficacy of the AnAPN1 malaria transmission-blocking vaccine antigen (preprint)
Bender NG , Khare P , Martinez J , Tweedell RE , Nyasembe VO , López-Gutiérrez B , Tripathi A , Miller D , Hamerly T , Vela EM , Howard RF , Nsango S , Cobb RR , Harbers M , Dinglasan RR . bioRxiv 2020 2020.11.29.402669 Malaria transmission-blocking vaccines (TBVs) are a critical tool for disease elimination. TBVs prevent completion of the developmental lifecycle of malarial parasites within the mosquito vector, effectively blocking subsequent infections. The mosquito midgut protein Anopheline alanyl aminopeptidase N (AnAPN1) is the leading, mosquito-based TBV antigen and structure-function studies have identified two Class II epitopes that induce potent transmission-blocking (T-B) antibodies. Here, we functionally screened new immunogens and down-selected to the UF6b construct that has two glycine-linked copies of the T-B epitopes. We established a process for manufacturing UF6b and evaluated in outbred female CD1 mice the immunogenicity of the preclinical product with the human-safe adjuvant Glucopyranosyl Lipid Adjuvant in a liposomal formulation with saponin QS21 (GLA-LSQ). UF6b:GLA-LSQ was immunogenic and immunofocused the humoral response to one of the key T-B epitopes resulting in potent T-B activity and establishing UF6b as a prime TBV candidate to aid in malaria elimination and eradication efforts.Competing Interest StatementThe authors have declared no competing interest. |

Some of those variants were designated as variants of concern/interest (VOC/VOI) by national or international authorities based on many factors including their potential impact on vaccines. To ascertain and rank the risk of VOCs and VOIs, we analyzed their ability to escape from vaccine-induced antibodies. The variants showed differential reductions in neutralization and replication titers by post-vaccination sera. Although the Omicron variant showed the most escape from neutralization, sera collected after a third dose of vaccine (booster sera) retained moderate neutralizing activity against that variant. Therefore, vaccination remains the most effective strategy to combat the COVID-19 pandemic. |
Retirement and cognitive aging in a racially diverse sample of older Americans
Andel R , Veal BM , Howard VJ , MacDonald LA , Judd SE , Crowe M . J Am Geriatr Soc 2023 71 (9) 2769-2778 BACKGROUND: Retirement represents a crucial transitional period for many adults with possible consequences for cognitive aging. We examined trajectories of cognitive change before and after retirement in Black and White adults. METHODS: Longitudinal examination of up to 10 years (mean = 7.1 ± 2.2 years) using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study-a national, longitudinal study of Black and White adults ≥45 years of age. Data were from 2226 members of the REGARDS study who retired around the time when an occupational ancillary survey was administered. Cognitive function was an average of z-scores for tests of verbal fluency, memory, and global function. RESULTS: Cognitive functioning was stable before retirement (Estimate = 0.05, p = 0.322), followed by a significant decline after retirement (Estimate = -0.15, p < 0.001). The decline was particularly pronounced in White (Estimate = -0.19, p < 0.001) compared with Black (Estimate = -0.07, p = 0.077) participants, twice as large in men (Estimate = -0.20, p < 0.001) compared with women (Estimate = -0.11, p < 0.001), highest among White men (Estimate = -0.22, p < 0.001) and lowest in Black women (Estimate = -0.04, p = 0.457). Greater post-retirement cognitive decline was also observed among participants who attended college (Estimate = -0.14, p = 0.016). While greater work complexity (Estimate = 0.92, p < 0.05) and higher income (Estimate = 1.03, p < 0.05) were related to better cognitive function at retirement, neither was significantly related to cognitive change after retirement. CONCLUSION: Cognitive functioning may decline at an accelerated rate immediately post-retirement, more so in White adults and men than Black adults and women. Lifelong structural inequalities including occupational segregation and other social determinants of cognitive health may obscure the role of retirement in cognitive aging. |
Reported Cases of Multisystem Inflammatory Syndrome in Children (MIS-C) Aged 12-20 Years in the United States Who Received COVID-19 Vaccine, December 2020 through August 2021 (preprint)

In the United States, reporting of MIS-C after vaccination is required under COVID-19 vaccine emergency use authorizations. This case series describes persons aged 12-20 years with MIS-C following COVID-19 vaccination reported to passive surveillance systems or through clinician outreach to CDC. Method(s): We investigated potential cases of MIS-C after COVID-19 vaccination reported to CDC's health department-based national MIS-C surveillance, the Vaccine Adverse Event Reporting System (VAERS, co-administered by CDC and the U.S. FDA), and CDC's Clinical Immunization Safety Assessment Project (CISA) from December 14, 2020, to August 31, 2021. We describe cases meeting the CDC MIS-C case definition. Any positive SARS-CoV-2 serology test satisfied the case criteria although anti-nucleocapsid antibody indicates SARS-CoV-2 infection, while anti-spike protein antibody indicates either infection or COVID-19 vaccination. Finding(s): We identified 21 persons with MIS-C after COVID-19 vaccination. Of these 21 persons, median age was 16 years (range, 12-20 years); 13 (62%) were male. All were hospitalized; 12 (57%) had intensive care unit admission, and all were discharged home. Fifteen (71%) of the 21 had laboratory evidence of past or recent SARS-CoV-2 infection, and six (29%) did not. Through August 2021, 21,335,331 persons aged 12-20 years had received >=1 dose of COVID-19 vaccine, making the overall reporting rate for MIS-C following vaccination 1.0 case per million persons receiving >=1 vaccine dose in this age group. The reporting rate for those without evidence of SARS-CoV-2 infection was 0.3 cases per million vaccinated persons. Interpretation(s): In our case series, we describe a small number of persons with MIS-C who had received >=1 COVID-19 vaccine dose before illness onset. Continued reporting of potential cases and surveillance for MIS-C illnesses after COVID-19 vaccination is warranted.

Method(s): Between October 1, 2021, and February 12, 2022, research staff consented and enrolled eligible participants who had fever, cough, or loss of taste or smell and sought outpatient medical care or clinical SARS-CoV-2 testing within 10 days of illness onset. Using the test-negative design, we compared the odds of receiving 2 or 3 mRNA COVID-19 vaccine doses among SARS-CoV-2 cases versus controls using logistic regression. Regression models were adjusted for study site, age, onset week, and prior SARS-CoV-2 infection. Vaccine effectiveness (VE) was calculated as (1 - adjusted odds ratio) x 100%. Result(s): Among 3847 participants included for analysis, 574 (32%) of 1775 tested positive for SARS-CoV-2 during the Delta predominant period and 1006 (56%) of 1794 participants tested positive during the Omicron predominant period. When Delta predominated, VE against symptomatic illness in outpatient settings was 63% (95% CI: 51% to 72%) among mRNA 2-dose recipients and 96% (95% CI: 93% to 98%) for 3-dose recipients. When Omicron predominated, VE was 21% (95% CI: -6% to 41%) among 2-dose recipients and 62% (95% CI: 48% to 72%) among 3-dose recipients. Conclusion(s): In this adult population, 3 mRNA COVID-19 vaccine doses provided substantial protection against symptomatic illness in outpatient settings when the Omicron variant became the predominant cause of COVID-19 in the U.S. These findings support the recommendation for a 3rd mRNA COVID-19 vaccine dose.

DNA viruses, including MPXV, have a lower SNP mutation rate than RNA viruses due to higher fidelity replication machinery. We identified a large genomic rearrangement in a MPXV sequence from a 2022 case in the state of Minnesota (MN), USA, from an abnormal, uneven MPXV read mapping coverage profile in whole-genome sequencing (WGS) data. We further screened WGS data of 206 U.S. MPXV samples and found seven (3.4 percent) sequenced genomes contained similar abnormal read coverage profiles that suggested putative large deletions or genomic rearrangements. Here, we present three MPXV genomes containing deletions ranging from 2.3 to 15 kb and four genomes containing more complex rearrangements. Five genomic changes were each only seen in one sample, but two sequences from linked cases shared an identical 2.3 kb deletion in the 3' terminal region. All samples were positive using VAC1 and Clade II (formerly West African)-specific MPXV diagnostic tests; however, large deletions and genomic rearrangements like the ones reported here have the potential to result in viruses in which the target of a PCR diagnostic test is deleted. The emergence of genomic rearrangements during the outbreak may have public health implications and highlight the importance of continued genomic surveillance.

Orphanhood vulnerabilities for violence and HIV by education, sex, and orphan type among 18-24-year-old youth: findings from the 2018 Lesotho violence against children and youth survey
Lee N , Self-Brown SR , Bachman G , Howard AL , Gilbert LK , Hegle J , Perry EW , Saul J , Behl I , Massetti GM . Psychol Health Med 2023 1-15 HIV and violence among orphans are key measures of vulnerability in low-resource settings. Although Lesotho has the second highest HIV adult prevalence rate (21.1%) in the world, and the prevalence of orphanhood (44.2%) and violence exposure (67.0%) is high, little research exist on orphanhood vulnerabilities for violence and HIV in Lesotho. Using data from 4,408 youth (18-24 years old) from Lesotho's 2018 Violence Against Children and Youth survey, a nationally representative cross-sectional household survey, the study examined associations among orphan status, violence, and HIV and assessed how associations differed by education, sex, and orphan type, using logistic regression. Orphans had higher odds of violence (aOR, 1.21; 95% CI, 1.01-1.46) and HIV (aOR, 1.69; 95% CI, 1.24-2.29). Having primary education or less (aOR, 1.43; 95% CI, 1.02-2.02), male sex (aOR, 1.74; 95% CI, 1.27-2.36), and being a paternal orphan (aOR, 1.43; 95% CI, 1.14-1.80) were significant interaction terms for violence. Orphans who completed primary school or less (aOR, 1.61; 95% CI, 1.09-2.39), female (aOR, 3.08; 95% CI, 2.14-4.42) and double orphans (aOR, 2.54; 95% CI, 1.56-4.13) had higher odds of HIV. These relationships highlight the importance of comprehensive strategies to support education and family strengthening for orphans as core violence and HIV prevention efforts. |
