Cervical cancer incidence in the US-affiliated Pacific Islands
Gopalani SV , Qin J , Baksa J , Thompson TD , Saraiya M , Senkomago V , Pordell P , Jeong Y , Palafox NA , Reichhardt M , Buenconsejo-Lum LE . JAMA Oncol 2024 IMPORTANCE: The World Health Organization has called for eliminating cervical cancer as a public health problem. Accurate and up-to-date estimates of population-based cervical cancer incidence are essential for monitoring progress toward elimination and informing local cancer control strategies, but these estimates are lacking for the US-Affiliated Pacific Islands (USAPI). OBJECTIVE: To calculate age-standardized incidence rates for cervical cancer in the 6 USAPI and compare these rates with rates in the US (50 states and the District of Columbia). DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used population-based data from the Pacific Regional Central Cancer Registry for women aged 20 years or older who were diagnosed with invasive cervical cancer from January 1, 2007, to December 31, 2020. The registry comprises data on all cervical cancers from the USAPI, which include 3 US territories (American Samoa, Commonwealth of the Northern Mariana Islands, and Guam) and 3 freely associated states (Federated States of Micronesia [FSM], Republic of the Marshall Islands [RMI], and Republic of Palau). Data were analyzed from July 10, 2023, to November 28, 2023. MAIN OUTCOMES AND MEASURES: The main outcome was age-standardized cervical cancer incidence rates, stratified by age, stage, and histologic code for the USAPI using population estimates from 3 different sources (US Census Bureau International Database, United Nations Population Division, and Pacific Data Hub). Rate ratios were calculated to compare incidence rates between the USAPI and the US. RESULTS: From 2007 to 2020, 409 cases of cervical cancer were diagnosed in the USAPI (median age at diagnosis, 46.0 years [25th-75th percentile, 39.0-55.0 years]), with an age-standardized incidence rate ranging from 21.7 (95% CI, 19.6-23.9) to 22.1 (95% CI, 20.0-24.4) per 100 000 women, depending on the population estimate. Incidence rates were highest in RMI, ranging from 58.1 (95% CI, 48.0-69.7) to 83.4 (95% CI, 68.3-101.0) per 100 000 women, followed by FSM, ranging from 28.7 (95% CI, 23.4-34.9) to 29.8 (95% CI, 24.3-36.3) per 100 000 women. Compared with the US, incidence rates were highest in RMI (rate ratio, 5.7 [95% CI, 4.7-6.8] to 8.2 [95% CI, 6.7-9.9]) and FSM (rate ratio; 2.8; 95% CI, 2.3-3.4). Of all cases in the USAPI, 213 (68.2%) were diagnosed at a late stage. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, cervical cancer remained a major public health issue in some USAPI, with RMI reporting the highest incidence rates. The findings suggest that improvements in human papillomavirus vaccination and cancer screening coverage through efforts tailored to the unique geographic, sociocultural, economic, and health care landscape of the USAPI may reduce the burden of cervical cancer. |
Epidemiology of invasive candidiasis
Bays DJ , Jenkins EN , Lyman M , Chiller T , Strong N , Ostrosky-Zeichner L , Hoenigl M , Pappas PG , Thompson Iii GR . Clin Epidemiol 2024 16 549-566 Invasive candidiasis (IC) is an increasingly prevalent, costly, and potentially fatal infection brought on by the opportunistic yeast, Candida. Previously, IC has predominantly been caused by C. albicans which is often drug susceptible. There has been a global trend towards decreasing rates of infection secondary to C. albicans and a rise in non-albicans species with a corresponding increase in drug resistance creating treatment challenges. With advances in management of malignancies, there has also been an increase in the population at risk from IC along with a corresponding increase in incidence of breakthrough IC infections. Additionally, the emergence of C. auris creates many challenges in management and prevention due to drug resistance and the organism's ability to transmit rapidly in the healthcare setting. While the development of novel antifungals is encouraging for future management, understanding the changing epidemiology of IC is a vital step in future management and prevention. |
Patterns and correlates of traumatic stress, depression, anxiety, and moral injury in U.S. health care providers late in the COVID-19 pandemic
Papa A , Okun AH , Barile JP , Jia H , Thompson WW , Guerin RJ . Psychol Trauma 2024 OBJECTIVE: Providing health care during the COVID-19 pandemic has been associated with a high mental health burden for health care providers. This study examined patterns of responses and correlates of class membership across commonly assessed mental health symptoms, psychosocial functioning, and moral injury for providers in the United States in Fall 2022. METHOD: A convenience sample of 1,504 primary care physicians, pediatricians, nurse practitioners, and physician assistants who had been in practice for three or more years (M(age) = 46.1 years, SD(age) = 11.3, 58% male) completed self-report measures in an online, opt-in panel survey from September to November 2022. RESULTS: Using latent class analysis, three classes were identified: No/Low Symptoms (64.8%), High Moral Injury (19.9%), and Elevated Symptoms (15.2%). Several factors were correlated with class membership including age, sex, social support, personal risk of COVID-19, pandemic-related work stressors, proportion of COVID-19 patients seen at the height of the pandemic, and death of a patient due to COVID-19. CONCLUSIONS: This study found high levels of mental health symptoms, and problems with psychosocial functioning and moral injury in health care providers well past the pandemic's peak. The results also demonstrated the importance of considering the unique contribution of moral injury to psychosocial functional difficulties experienced by health care providers during the pandemic given their defined role as essential workers. These findings have implications for preventing and managing mental health problems and burnout among providers postpandemic as well as for future pandemics at both the organizational and individual levels.

Respiratory Viral Infections from 2015 to 2022 in the HIVE Cohort of American Households: Incidence, illness characteristics, and seasonality
Monto AS , Foster-Tucker JE , Callear AP , Leis AM , Godonou ET , Smith M , Truscon R , Johnson E , Thomas LJ , Thompson MS , Fry AM , Flannery B , Malosh RE , Petrie JG , Lauring AS , Martin ET . J Infect Dis 2024 BACKGROUND: Viral respiratory illnesses are the most common acute illnesses experienced and generally follow a predicted pattern over time. The SARS-CoV-2 pandemic interrupted that pattern. METHODS: The HIVE (Household Influenza Vaccine Evaluation) study was established in 2010 to follow a cohort of Southeast Michigan households over time. Initially focused on influenza, surveillance was expanded to include other major respiratory pathogens, and, starting in 2015, the population was followed year-round. Symptoms of acute illness were reported, and respiratory specimens were collected and tested to identify viral infections. Based on the known population being followed, virus-specific incidence was calculated. RESULTS: From 2015 to 2022, 1755 participants were followed in HIVE for 7785 person-years with 7833 illnesses documented. Before the pandemic, rhinovirus (RV) and common cold human coronaviruses (HCoVs) were the viruses most frequently identified, and incidence decreased with increasing age. Type A influenza was next but with comparable incidence by age. Parainfluenza and respiratory syncytial viruses were less frequent overall, followed by human metapneumoviruses. Incidence was highest in young children, but infections were frequently documented in all age groups. Seasonality followed patterns established decades ago. The SARS-CoV-2 pandemic disrupted these patterns, except for RV and, to a lesser extent, HCoVs. In the first two years of the pandemic, RV incidence far exceeded that of SARS-CoV-2. CONCLUSION: Longitudinal cohort studies are important in comparing the incidence, seasonality, and characteristics of different respiratory viral infections. Studies documented the differential effect of the pandemic on the incidence of respiratory viruses in addition to SARS-CoV-2. |
Geographical distribution of the Cryptococcus gattii species complex: a systematic review
Poplin V , Smith C , Caceres DH , Herkert PF , Jegede O , Thompson GR 3rd , Baddley JW , Schwartz IS , Kubat R , Deka MA , Toda M , Lockhart SR , Chiller T , Hagen F , Bahr NC . Lancet Microbe 2024 100921 The taxonomy of the Cryptococcus gattii species complex continues to evolve, and has been divided into five pathogenic species. The objective of this systematic review was to summarise the geographical distribution of the C gattii species complex and the species within the C gattii species complex. We searched PubMed for articles related to human, animal, ecological, or laboratory-based studies of C gattii species complex isolates with traceable geographical origin published from January, 1970, until September, 2021. Having extracted their geographical origin, we used ArcMap to construct maps according to the highest degree of resolution allowed by their reported taxonomy, to reflect the most likely area of transmission on the basis of published reports of human isolates. 604 such articles were included in the study. This review indicated that although C gattii species complex isolates have been reported globally, understanding their heterogeneous geographical distribution by species can have implications for researchers and clinicians in formulating research questions and considering diagnostic quandaries. |
Incidence of laboratory-confirmed influenza and RSV and associated presenteeism and absenteeism among healthcare personnel, Israel, influenza seasons 2016 to 2019
Azziz-Baumgartner E , Hirsch A , Yoo YM , Peretz A , Greenberg D , Avni YS , Glatman-Freedman A , Mandelboim M , MacNeil A , Martin ET , Newes-Adeyi G , Thompson M , Monto AS , Balicer RD , Levine MZ , Katz MA . Euro Surveill 2024 29 (31) BackgroundHealthcare personnel (HCP) are at high risk for respiratory infections through occupational exposure to respiratory viruses.AimWe used data from a prospective influenza vaccine effectiveness study in HCP to quantify the incidence of acute respiratory infections (ARI) and their associated presenteeism and absenteeism.MethodsAt the start and end of each season, HCP at two Israeli hospitals provided serum to screen for antibodies to influenza virus using the haemagglutination inhibition assay. During the season, active monitoring for the development of ARI symptoms was conducted twice a week by RT-PCR testing of nasal swabs for influenza and respiratory syncytial virus (RSV). Workplace presenteeism and absenteeism were documented. We calculated incidences of influenza- and RSV-associated ARI and applied sampling weights to make estimates representative of the source population.ResultsThe median age of 2,505 participating HCP was 41 years, and 70% were female. Incidence was 9.1 per 100 person-seasons (95% CI: 5.8-14.2) for RT-PCR-confirmed influenza and 2.5 per 100 person-seasons (95% CI: 0.9-7.1) for RSV illness. Each season, 18-23% of unvaccinated and influenza-negative HCP seroconverted. The incidence of seroconversion or RT-PCR-confirmed influenza was 27.5 per 100 person-seasons (95% CI: 17.8-42.5). Work during illness occurred in 92% (95% CI: 91-93) of ARI episodes, absence from work in 38% (95% CI: 36-40).ConclusionInfluenza virus and RSV infections and associated presenteeism and absenteeism were common among HCP. Improving vaccination uptake among HCP, infection control, and encouraging sick HCP to stay home are important strategies to reduce ARI incidence and decrease the risk of in-hospital transmission. |
Pediatric lipid screening prevalence using nationwide electronic medical records
Thompson-Paul AM , Kraus EM , Porter RM , Pierce SL , Kompaniyets L , Sekkarie A , Goodman AB , Jackson SL . JAMA Netw Open 2024 7 (7) e2421724 IMPORTANCE: Universal screening to identify unfavorable lipid levels is recommended for US children aged 9 to 11 years and adolescents aged 17 to 21 years (hereafter, young adults); however, screening benefits in these individuals have been questioned. Current use of lipid screening and prevalence of elevated lipid measurements among US youths is not well understood. OBJECTIVE: To investigate the prevalence of ambulatory pediatric lipid screening and elevated or abnormal lipid measurements among US screened youths by patient characteristic and test type. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used data from the IQVIA Ambulatory Electronic Medical Record database and included youths aged 9 to 21 years with 1 or more valid measurement of height and weight during the observation period (2018-2021). Body mass index (BMI) was calculated and categorized using standard pediatric BMI percentiles (9-19 years) and adult BMI categories (≥20 years). The data were analyzed from October 6, 2022, to January 18, 2023. MAIN OUTCOMES AND MEASURES: Lipid measurements were defined as abnormal if 1 or more of the following test results was identified: total cholesterol (≥200 mg/dL), low-density lipoprotein cholesterol (≥130 mg/dL), very low-density lipoprotein cholesterol (≥31 mg/dL), non-high-density lipoprotein cholesterol (≥145 mg/dL), and triglycerides (≥100 mg/dL for children aged 9 years or ≥130 mg/dL for patients aged 10-21 years). After adjustment for age group, sex, race and ethnicity, and BMI category, adjusted prevalence ratios (aPRs) and 95% CIs were calculated. RESULTS: Among 3 226 002 youths (23.9% aged 9-11 years, 34.8% aged 12-16 years, and 41.3% aged 17-21 years; 1 723 292 females [53.4%]; 60.0% White patients, 9.5% Black patients, and 2.4% Asian patients), 11.3% had 1 or more documented lipid screening tests. The frequency of lipid screening increased by age group (9-11 years, 9.0%; 12-16 years, 11.1%; 17-21 years, 12.9%) and BMI category (range, 9.2% [healthy weight] to 21.9% [severe obesity]). Among those screened, 30.2% had abnormal lipid levels. Compared with youths with a healthy weight, prevalence of an abnormal result was higher among those with overweight (aPR, 1.58; 95% CI, 1.56-1.61), moderate obesity (aPR, 2.16; 95% CI, 2.14-2.19), and severe obesity (aPR, 2.53; 95% CI, 2.50-2.57). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of prevalence of lipid screening among US youths aged 9 to 21 years, approximately 1 in 10 were screened. Among them, abnormal lipid levels were identified in 1 in 3 youths overall and 1 in 2 youths with severe obesity. Health care professionals should consider implementing lipid screening among children aged 9 to 11 years, young adults aged 17 to 21 years, and all youths at high cardiovascular risk. |
Estimating the prevalence of injection drug use among acute hepatitis C cases from a national surveillance system: Application of random forest-based multiple imputation
Yin S , Ly KN , Barker LK , Bixler D , Thompson ND , Gupta N . J Public Health Manag Pract 2024 30 (5) 733-743 BACKGROUND: Injection drug use (IDU) is a major contributor to the syndemic of viral hepatitis, human immunodeficiency virus, and drug overdose. However, information on IDU is frequently missing in national viral hepatitis surveillance data, which limits our understanding of the full extent of IDU-associated infections. Multiple imputation by chained equations (MICE) has become a popular approach to address missing data, but its application for IDU imputation is less studied. METHODS: Using the 2019-2021 National Notifiable Diseases Surveillance System acute hepatitis C case data and publicly available county-level measures, we evaluated listwise deletion (LD) and 3 models imputing missing IDU data through MICE: parametric logistic regression, semi-parametric predictive mean matching (PMM), and nonparametric random forest (RF) (both standard RF [sRF] and fast implementation of RF [fRF]). RESULTS: The estimated IDU prevalence among acute hepatitis C cases increased from 63.5% by LD to 65.1% by logistic regression, 66.9% by PMM, 76.0% by sRF, and 85.1% by fRF. Evaluation studies showed that RF-based MICE imputation, especially fRF, has the highest accuracy (as measured by smallest raw bias, percent bias, and root mean square error) and highest efficiency (as measured by smallest 95% confidence interval width) compared to LD and other models. Sensitivity analyses indicated that fRF remained robust when data were missing not at random. CONCLUSION: Our analysis suggested that RF-based MICE imputation, especially fRF, could be a valuable approach for addressing missing IDU data in the context of population-based surveillance systems like National Notifiable Diseases Surveillance System. The inclusion of imputed IDU data may enhance the effectiveness of future surveillance and prevention efforts for the IDU-driven syndemic. |
Potential impact of curative and preventive interventions toward hepatitis C elimination in people who inject drugs-A network modeling study
Zhu L , Thompson WW , Hagan L , Randall LM , Rudolph AE , Young AM , Havens JR , Salomon JA , Linas BP . Int J Drug Policy 2024 130 104539 BACKGROUND: Injection-equipment-sharing networks play an important role in hepatitis C virus (HCV) transmission among people who inject drugs (PWID). Direct-acting antiviral (DAA) treatments for HCV infection and interventions to prevent HCV transmission are critical components of an overall hepatitis C elimination strategy, but how they contribute to the elimination outcomes in different PWID network settings are unclear. METHODS: We developed an agent-based network model of HCV transmission through the sharing of injection equipment among PWID and parameterized and calibrated the model with rural PWID data in the United States. We modeled curative and preventive interventions at annual coverage levels of 12.5 %, 25 %, or 37.5 % (cumulative percentage of eligible individuals engaged), and two allocation approaches: random vs targeting PWID with more injection partners (hereafter 'degree-based'). We compared the impact of these intervention strategies on prevalence and incidence of HCV infections. We conducted sensitivity analysis on key parameters governing the effects of curative and preventive interventions and PWID network characteristics. RESULTS: Combining curative and preventive interventions at 37.5 % annual coverage with degree-based allocation decreased prevalence and incidence of HCV infection by 67 % and 70 % over two years, respectively. Curative interventions decreased prevalence by six to 12 times more than preventive interventions, while curative and preventive interventions had comparable effectiveness on reducing incidence. Intervention impact increased with coverage almost linearly across all intervention strategies, and degree-based allocation was always more effective than random allocation, especially for preventive interventions. Results were sensitive to parameter values defining intervention effects and network mean degree. CONCLUSION: DAA treatments are effective in reducing both prevalence and incidence of HCV infection in PWID, but preventive interventions play a significant role in reducing incidence when intervention coverage is low. Increasing coverage, including efforts in reaching individuals with the most injection partners, preventing reinfection, and improving compliance and retention in preventive services can substantially improve the outcomes. PWID network characteristics should be considered when designing hepatitis C elimination programs. |
Incidence and survival of pediatric and adult hepatocellular carcinoma, United States, 2001-2020
Arnett A , Siegel DA , Dai S , Thompson TD , Foster J , di Pierro EJ , Momin B , Lupo PJ , Heczey A . Cancer Epidemiol 2024 92 102610 BACKGROUND: Hepatocellular carcinoma accounts for approximately 80 % of liver neoplasms. Globally, hepatocellular carcinoma ranks as the third most lethal cancer, with the number of deaths expected to further increase by 2040. In adults, disparities in incidence and survival are well described while pediatric epidemiology is not well characterized. We describe incidence and survival for pediatric (ages 0-19 years) hepatocellular carcinoma cases and compare these measures to adults (ages ≥ 20 years) diagnosed with hepatocellular carcinoma. METHODS: We assessed incidence data from the US Cancer Statistics database during 2003-2020 and 5-year survival from the National Program of Cancer Registries during 2001-2019. Incidence trends were determined by annual percent change (APC) and average APC (AAPC) using joinpoint regression. Five-year survival was evaluated by relative survival, and all-cause survival was estimated using multivariate Cox modeling. Corresponding 95 % confidence intervals (CI) were calculated for all analyses. RESULTS: Incidence rate per 100,000 persons was 0.056 (95 %CI:0.052-0.060) for pediatric cases and 7.793 (7.767-7.819) for adults. Incidence was stable in the pediatric population (0.3 AAPC, - 1.1 to 1.7). In contrast, after periods of increase, incidence declined in adults after 2015 (-1.5 APC). Relative survival increased over time for both pediatric and adult ages and was higher for children and adolescents (46.4 %, 95 %CI:42.4-50.3) than adults (20.7 %, 95 %CI:20.5-20.9). Regression modeling showed that non-Hispanic Black race and ethnicity was associated with higher risk of death in children and adolescents (1.48, 95 %CI:1.07-2.05) and adults (1.11, 95 %CI:1.09-1.12) compared to non-Hispanic white race and ethnicity. CONCLUSIONS: Between 2003 and 2020 in the United States, pediatric incidence was stable while incidence in adults began to decline after 2015. Survival was higher across all stages for children and adolescents compared to adults. Non-Hispanic Black race and ethnicity showed a higher risk of death for both age groups. Further studies could explore the factors that influence these outcome disparities. |
Breast cancer incidence and stage at diagnosis in the six US-Affiliated Pacific Islands
Gopalani SV , Qin J , Baksa J , Thompson TD , Senkomago V , Pordell P , Jeong Y , Reichhardt M , Palafox N , Buenconsejo-Lum L . Cancer Epidemiol 2024 92 102611 BACKGROUND: Breast cancer is the most common cancer diagnosed among women globally and in the United States (US); however, its incidence in the six US-Affiliated Pacific Islands (USAPI) remains less characterized. METHODS: We analyzed data from a population-based cancer registry using different population estimates to calculate incidence rates for breast cancer among women aged >20 years in the USAPI. Rate ratios and 95 % confidence intervals (CI) were calculated to compare incidence rates between the USAPI and the US (50 states and the District of Columbia). RESULTS: From 2007-2020, 1118 new cases of breast cancer were diagnosed in the USAPI, with 66.3 % (n = 741) of cases reported in Guam. Age-standardized incidence rates ranged from 66.4 to 68.7 per 100,000 women in USAPI and 101.1-110.5 per 100,000 women in Guam. Compared to the US, incidence rates were lower in USAPI, with rate ratios ranging from 0.38 (95 % CI: 0.36, 0.40) to 0.39 (95 % CI: 0.37, 0.42). The proportion of late-stage cancer was significantly higher in the USAPI (48.7 %) than in the US (34.0 %), particularly in the Federated States of Micronesia (78.7 %) and Palau (73.1 %). CONCLUSIONS: Breast cancer incidence rates were lower in the USAPI than in the US; however, late-stage diagnoses were disproportionately higher. Low incidence and late-stage cancers may signal challenges in screening, cancer surveillance, and health care access and resources. Expanding access to timely breast cancer screening, diagnosis, and treatment could reduce the proportion of late-stage cancers and improve survival in the USAPI. |
Medicaid expansion and restriction policies for hepatitis C treatment
Furukawa NW , Ingber SZ , Symum H , Rapposelli KK , Teshale EH , Thompson WW , Zhu W , Roberts HW , Gupta N . JAMA Netw Open 2024 7 (7) e2422406 IMPORTANCE: Hepatitis C can be cured with direct-acting antivirals (DAAs), but Medicaid programs have implemented fibrosis, sobriety, and prescriber restrictions to control costs. Although restrictions are easing, understanding their association with hepatitis C treatment rates is crucial to inform policies that increase access to lifesaving treatment. OBJECTIVE: To estimate the association of jurisdictional (50 states and Washington, DC) DAA restrictions and Medicaid expansion with the number of Medicaid recipients with filled prescriptions for DAAs. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used publicly available Medicaid documents and claims data from January 1, 2014, to December 31, 2021, to compare the number of unique Medicaid recipients treated with DAAs in each jurisdiction year with Medicaid expansion status and categories of fibrosis, sobriety, and prescriber restrictions. Medicaid recipients from all 50 states and Washington, DC, during the study period were included. Multilevel Poisson regression was used to estimate the association between Medicaid expansion and DAA restrictive policies on jurisdictional Medicaid DAA prescription fills. Data were analyzed initially from August 15 to November 15, 2023, and subsequently from April 15 to May 9, 2024. EXPOSURES: Jurisdictional Medicaid expansion status and fibrosis, sobriety, and prescriber DAA restrictions. MAIN OUTCOMES AND MEASURES: Number of people treated with DAAs per 100 000 Medicaid recipients per year. RESULTS: A total of 381 373 Medicaid recipients filled DAA prescriptions during the study period (57.3% aged 45-64 years; 58.7% men; 15.2% non-Hispanic Black and 52.2% non-Hispanic White). Medicaid nonexpansion jurisdictions had fewer filled DAA prescriptions per 100 000 Medicaid recipients per year than expansion jurisdictions (38.6 vs 86.6; adjusted relative risk [ARR], 0.56 [95% CI, 0.52-0.61]). Jurisdictions with F3 to F4 (34.0 per 100 000 Medicaid recipients per year; ARR, 0.39 [95% CI, 0.37-0.66]) or F1 to F2 fibrosis restrictions (61.9 per 100 000 Medicaid recipients per year; ARR, 0.62 [95% CI, 0.59-0.66]) had lower treatment rates than jurisdictions without fibrosis restrictions (94.8 per 100 000 Medicaid recipients per year). Compared with no sobriety restrictions (113.5 per 100 000 Medicaid recipients per year), 6 to 12 months of sobriety (38.3 per 100 000 Medicaid recipients per year; ARR, 0.65 [95% CI, 0.61-0.71]) and screening and counseling requirements (84.7 per 100 000 Medicaid recipients per year; ARR, 0.87 [95% CI, 0.83-0.92]) were associated with reduced treatment rates, while 1 to 5 months of sobriety was not statistically significantly different. Compared with no prescriber restrictions (97.8 per 100 000 Medicaid recipients per year), specialist consult restrictions was associated with increased treatment (66.2 per 100 000 Medicaid recipients per year; ARR, 1.05 [95% CI, 1.00-1.10]), while specialist required restrictions were not statistically significant. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, Medicaid nonexpansion status, fibrosis, and sobriety restrictions were associated with a reduction in the number of people with Medicaid who were treated for hepatitis C. Removing DAA restrictions might facilitate treatment of more people diagnosed with hepatitis C. |
Testing trends and co-testing patterns for HIV, hepatitis C and sexually transmitted infections (STIs) in Emergency departments
Symum H , Van Handel M , Sandul A , Hutchinson A , Tsang CA , Pearson WS , Delaney KP , Cooley LA , Gift TL , Hoover KW , Thompson WW . Preventive Med Reports 2024 44 Background: Many underserved populations use Emergency Department (EDs) as primary sources of care, representing an important opportunity to provide infectious disease testing and linkage to care. We explored national ED testing trends and co-testing patterns for HIV, hepatitis C, and sexually transmitted infections (STIs). Methods: We used 2010–2019 Healthcare Cost and Utilization Project, Nationwide Emergency Department Sample data to estimate ED visit testing rates for HIV, hepatitis C, chlamydia, gonorrhea, and syphilis infections, identified by Current Procedural Terminology codes. Trends and co-testing (visit with tests for > 1 infection) patterns were analyzed by sociodemographic, hospital, and visit characteristics. Trends were evaluated as the average annual percentage change (AAPC) using the Joinpoint Regression. Results: During 2010–2019, testing events per 1000 visits (AAPCs) increased for HIV from 1.3 to 4.2 (16.3 %), hepatitis C from 0.4 to 2.2 (25.1 %), chlamydia from 9.1 to 16.0 (6.6 %), gonorrhea from 8.4 to 15.7 (7.4 %), and syphilis from 0.7 to 2.0 (12.9 %). Rate increases varied by several characteristics across infections. The largest AAPC increases were among visits by groups with lower base rate testing in 2010, including persons aged ≥ 65 years (HIV: 36.4 %), with Medicaid (HIV: 43.8 %), in the lowest income quintile (hepatitis C: 36.9 %), living in the West (syphilis: 49.4 %) and with non-emergency diagnoses (hepatitis C: 44.1 %). Co-testing increased significantly for all infections except hepatitis C. Conclusions: HIV, hepatitis C, and STI testing increased in EDs during 2010–2019; however, co-testing patterns were inconsistent. Co-testing may improve diagnosis and linkage to care, especially in areas experiencing higher rates of infection. © 2024 |
Scrotal cancer incidence rates and trends-United States, 1999-2020
Mix JM , Gopalani SV , Miller M , Saraiya M , Darragh TM , Lynch CF , Thompson TD , Senkomago V , Greek A , Tucker TC , Unger ER . Urology 2024 OBJECTIVE: To examine population-level scrotal cancer incidence rates and trends among adult men in the United States. METHODS: Data from the United States Cancer Statistics, covering approximately 96% of the United States population, were analyzed to calculate age-standardized incidence rates of scrotal cancer among men aged 18 years and older from 1999 to 2020. Trends in incidence rates were evaluated by age, race and ethnicity, Census region, and histology using joinpoint regression. RESULTS: Overall, 4669 men were diagnosed with scrotal cancer (0.20 per 100,000). Incidence rates were highest among men aged 70 years and older (0.82 per 100,000). Rates were higher among non-Hispanic Asian or Pacific Islander men (0.31 per 100,000) compared to other race and ethnicity groups. The most common histologic subtypes were squamous cell carcinoma (35.9%), extramammary Paget disease (20.8%), and sarcoma (20.5%). Incidence rates decreased by 2.9% per year from 1999 to 2019 for non-Hispanic Asian or Pacific Islander men, decreased by 8.1% per year from 1999 to 2006 for basal cell carcinomas, and increased by 1.8% per year from 1999 to 2019 for extramammary Paget disease; otherwise, rates remained stable for all other variables examined. CONCLUSION: While scrotal cancer incidence rates were higher than previously reported, rates were still low and stable over time. |
Knowledge, attitudes, and practices associated with influenza vaccine uptake among healthcare personnel in Israel during three influenza seasons, 2016-2019

Vaccine 2024 INTRODUCTION: Despite a longstanding Israel Ministry of Health recommendation that all healthcare personnel (HCP) receive a seasonal influenza vaccine, vaccine uptake among HCP remains below the country's target of 60% coverage. To understand factors related to vaccine hesitancy, we used data from a prospective three-year (2016-2019) influenza vaccine effectiveness study among Israeli HCP to examine knowledge, attitudes, and practices (KAP) about influenza vaccination and their association with vaccine uptake. METHODS: At the start of each influenza season, all participating HCP completed a questionnaire that included questions about socio-demographic and occupational characteristics, health status, and KAP related to seasonal influenza vaccination. We extracted vaccination history from electronic medical records and employee vaccination registries. We used logistic regression models to identify demographic and occupational factors, and KAP about influenza vaccination, associated with receipt of vaccination. RESULT: A total of 2,126 HCP were enrolled and had available data on vaccination history. Their median age was 42 years [IQR 35-52], and 73 % self-identified as female. Influenza vaccine uptake in 2016, 2017 and 2018 was 46 %, 48 % and 47 %, respectively. Overall, 36 % of HCP had received an influenza vaccine in ≥ 4 of the eight years prior. HCP aged 35-49 years were less likely to receive influenza vaccine compared to HCP aged ≥ 50 years (OR: 0.81 [95 % CI: 0.67-0.98]). Nurses and allied personnel were less likely to receive influenza vaccine compared to physicians (OR: 0.63 [95 % CI: 0.50-0.78] and OR: 0.53 [95 % CI: 0.40-0.70], respectively). The emotional benefit of vaccination (e.g., anticipating regret if not vaccinated) and the perception of vaccine safety were factors associated with vaccine uptake (OR: 7.60 [95 % CI: 6.27-9.22] and OR: 3.43 [95 % CI:2.91-4.03], respectively). CONCLUSION: Among HCP at two hospitals in Israel, less than half received an annual influenza vaccine. Older HCP, physicians, and those who reported the emotional benefit of vaccination or agreed that influenza vaccines are safe were more likely to be vaccinated. Future influenza vaccination campaigns could focus on these demographic groups and tailor messages emphasizing the emotional benefits of vaccination and vaccine safety to increase seasonal influenza vaccine uptake among HCP in Israel. |

Engaging community health workers in primary care practices: Provider understanding of roles, benefits, and barriers
Rohan EA , Townsend JS , Bermudez AT , Thompson HL , Holman DM , Reza A , Tharpe FS , Wennerstrom A . J Ambul Care Manage 2024 Community health workers (CHWs) are increasingly addressing health disparities in primary care settings; however, there is little information about how primary care practitioners (PCPs) interact with CHWs or perceive CHW roles. We examined PCP engagement with CHWs in adult primary care settings. Overall, 55% of 1504 PCPs reported working with CHWs; involvement with CHWs differed by some PCP demographic and practice-related factors. While PCPs perceived CHWs as engaging in most nationally endorsed CHW roles, they identified several barriers to integrating CHWs into care teams. Findings can inform ongoing efforts to advance health equity through integrating CHWs into primary care practices. |

J Infect Dis 2024 229 (5) 1451-1459 BACKGROUND: Annual influenza vaccination is recommended for older adults but repeated vaccination with standard-dose influenza vaccine has been linked to reduced immunogenicity and effectiveness, especially against A(H3N2) viruses. METHODS: Community-dwelling Hong Kong adults aged 65-82 years were randomly allocated to receive 2017-2018 standard-dose quadrivalent, MF59-adjuvanted trivalent, high-dose trivalent, and recombinant-HA quadrivalent vaccination. Antibody response to unchanged A(H3N2) vaccine antigen was compared among participants with and without self-reported prior year (2016-2017) standard-dose vaccination. RESULTS: Mean fold rise (MFR) in antibody titers from day 0 to day 30 by hemagglutination inhibition and virus microneutralization assays were lower among 2017-2018 standard-dose and enhanced vaccine recipients with (range, 1.7-3.0) versus without (range, 4.3-14.3) prior 2016-2017 vaccination. MFR was significantly reduced by about one-half to four-fifths for previously vaccinated recipients of standard-dose and all 3 enhanced vaccines (β range, .21-.48). Among prior-year vaccinated older adults, enhanced vaccines induced higher 1.43 to 2.39-fold geometric mean titers and 1.28 to 1.74-fold MFR versus standard-dose vaccine by microneutralization assay. CONCLUSIONS: In the context of unchanged A(H3N2) vaccine strain, prior-year vaccination was associated with reduced antibody response among both standard-dose and enhanced influenza vaccine recipients. Enhanced vaccines improved antibody response among older adults with prior-year standard-dose vaccination. |
Hypertension prevalence and control among people with and without HIV - United States, 2022
Weng X , Kompaniyets L , Buchacz K , Thompson-Paul AM , Woodruff RC , Hoover KW , Huang YA , Li J , Jackson SL . Am J Hypertens 2024 BACKGROUND: People with HIV (PWH) have higher rates of cardiovascular disease than people without HIV. However, limited information exists about hypertension prevalence and associated risk factors in PWH. METHODS: This cross-sectional study included adult patients in the 2022 IQVIATM Ambulatory Electronic Medical Record - US data. HIV was identified based on ≥2 HIV diagnosis codes or a positive HIV test. Hypertension was identified by diagnosis codes, ≥2 blood pressure (BP) readings ≥130/80 mmHg, or an antihypertensive medication prescription. Among those with hypertension, control was defined as most recent BP <130/80 mmHg. Logistic models using marginal standardization method were used to estimate adjusted prevalence ratios (aPR) of hypertension and hypertension control among all patients and PWH specifically, controlling for covariates. RESULTS: Of 7,533,379 patients, 19,102 (0.3%) had HIV. PWH had higher hypertension prevalence (66% vs 54%, aPR:1.14, 95% CI: 1.13-1.15) compared with people without HIV. Among persons with hypertension, PWH were more likely to have controlled hypertension (aPR: 1.10, 95% CI: 1.07-1.13) compared with people without HIV. Among PWH, those from the South were more likely to have hypertension (aPR: 1.07, 95% CI: 1.02-1.12) than PWH from the Northeast, while Black PWH were less likely to have controlled hypertension (aPR: 0.72, 95% CI: 0.67-0.77) than White PWH. CONCLUSIONS: PWH were more likely to have hypertension than people without HIV. Geographic and racial disparities in hypertension prevalence and control were observed among PWH. Optimal care for PWH includes comprehensive strategies to screen for, prevent, and manage hypertension. |
Incidence and survival of pediatric and adult hepatocellular carcinoma, United States, 2001-2020
Arnett A , Siegel DA , Dai S , Thompson TD , Foster J , di Pierro EJ , Momin B , Lupo PJ , Heczey A . medRxiv 2024 IMPORTANCE: Hepatocellular carcinoma accounts for approximately 80% of liver neoplasms. Globally, hepatocellular carcinoma ranks as the third most lethal cancer, with the number of deaths expected to further increase by 2040. In adults, disparities in incidence and survival are well described while pediatric epidemiology is not well characterized. OBJECTIVE: To describe incidence and survival for pediatric (ages 0-19 years) hepatocellular carcinoma cases and compare these measures to adults (ages ≥20 years) diagnosed with hepatocellular carcinoma. We evaluated demographic factors and clinical characteristics that influence incidence and outcomes. DESIGN: Population-based cohort study. SETTING: Incidence data from the US Cancer Statistics database from 2003 to 2020 and 5-year relative survival from the National Program of Cancer Registries from 2001 to 2019, covering 97% and 83% of the US population, respectively. PARTICIPANTS: 355,349 US Cancer Statistics and 257,406 the National Program of Cancer Registries patients were identified using ICD-O-3 C22.0 and 8170-5 codes. MAIN OUTCOMES AND MEASURES: Incidence annual percent change (APC) and average APC (AAPC) using joinpoint regression. Five-year relative survival. All-cause survival estimated using multivariate Cox modeling. Corresponding 95% confidence intervals (CI) were calculated. RESULTS: Incidence rate per 100,000 persons was 0.056 (95%CI:0.052-0.060) for pediatric cases and 7.793 (7.767-7.819) for adults. Incidence was stable in the pediatric population (0.3 AAPC, -1.1-1.7). In contrast, after periods of increase, incidence declined in adults after 2015 (-1.5 APC). Relative survival increased over time for both pediatric and adult ages and was higher for children and adolescents (46.4%, 95%CI:42.4-50.3) than adults (20.7%, 95%CI:20.5-20.9) overall and when stratified by stage. Regression modeling showed that non-Hispanic Black race and ethnicity was associated with higher risk of death in children and adolescents (1.48, 95%CI:1.07-2.05) and adults (1.11, 95%CI:1.09-1.12) compared to non-Hispanic white race and ethnicity. CONCLUSIONS AND RELEVANCE: Between 2003 and 2020 in the United States, pediatric incidence was stable while incidence in adults began to decline after 2015. Survival was higher across all stages for children and adolescents compared to adults. Non-Hispanic Black race and ethnicity showed a higher risk of death for both age groups. Further studies could explore the factors that influence these outcome disparities. |

Clin Microbiol Rev 2024 e0007423 SUMMARYFungal infections are on the rise, driven by a growing population at risk and climate change. Currently available antifungals include only five classes, and their utility and efficacy in antifungal treatment are limited by one or more of innate or acquired resistance in some fungi, poor penetration into "sequestered" sites, and agent-specific side effect which require frequent patient reassessment and monitoring. Agents with novel mechanisms, favorable pharmacokinetic (PK) profiles including good oral bioavailability, and fungicidal mechanism(s) are urgently needed. Here, we provide a comprehensive review of novel antifungal agents, with both improved known mechanisms of actions and new antifungal classes, currently in clinical development for treating invasive yeast, mold (filamentous fungi), Pneumocystis jirovecii infections, and dimorphic fungi (endemic mycoses). We further focus on inhaled antifungals and the role of immunotherapy in tackling fungal infections, and the specific PK/pharmacodynamic profiles, tissue distributions as well as drug-drug interactions of novel antifungals. Finally, we review antifungal resistance mechanisms, the role of use of antifungal pesticides in agriculture as drivers of drug resistance, and detail detection methods for antifungal resistance. |
Immunogenicity of quadrivalent human papillomavirus vaccine among Alaska Native children aged 9-14 years at 5 years after vaccination
Davis BM , Blake I , Panicker G , Meites E , Thompson G , Geis J , Bruden D , Fischer M , Singleton R , Unger ER , Markowitz LE , Bruce MG . Vaccine 2024 BACKGROUND: Persistent human papillomavirus (HPV) infection can cause anogenital and oropharyngeal cancers. Many HPV infections and HPV-associated cancers are vaccine-preventable. Studies suggest long-term persistence of vaccine-induced antibodies. However, data are limited among Alaska Native people. METHODS: During 2011-2014, we enrolled Alaska Native children aged 9-14 years who received a 3-dose series of quadrivalent HPV vaccine (4vHPV). We collected sera at 1 month and 1, 2, 3, and 5 years post-vaccination to evaluate trends in type-specific immunoglobulin G antibody concentrations for the 4vHPV types (HPV 6/11/16/18). RESULTS: All participants (N = 469) had detectable antibodies against all 4vHPV types at all timepoints post-vaccination. For all 4vHPV types, antibody levels peaked by 1 month post-vaccination and gradually declined in subsequent years. At 5 years post-vaccination, antibody levels were higher among children who received 4vHPV at a younger age. CONCLUSIONS: Alaska Native children maintained antibodies against all 4vHPV types at 5 years post-vaccination. |
The impact of adjusting for hysterectomy prevalence on cervical cancer incidence rates and trends among women aged 30 years and older - United States, 2001-2019
Gopalani SV , Sawaya GF , Rositch AF , Dasari S , Thompson TD , Mix JM , Saraiya M . Am J Epidemiol 2024 Hysterectomy protects against cervical cancer when the cervix is removed. However, measures of cervical cancer incidence often fail to exclude women with a hysterectomy from the population at risk denominator, underestimating and distorting disease burden. In this study, we estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System surveys to remove the women who were not at risk of cervical cancer from the denominator and combined these estimates with the United States Cancer Statistics data. From these data, we calculated age-specific and age-standardized incidence rates for women aged >30 years from 2001-2019, adjusted for hysterectomy prevalence. We calculated the difference between unadjusted and adjusted incidence rates and examined trends by histology, age, race and ethnicity, and geographic region using Joinpoint regression. The hysterectomy-adjusted cervical cancer incidence rate from 2001-2019 was 16.7 per 100,000 women-34.6% higher than the unadjusted rate. After adjustment, incidence rates were higher by approximately 55% among Black women, 56% among those living in the East South Central division, and 90% among women aged 70-79 and >80 years. These findings underscore the importance of adjusting for hysterectomy prevalence to avoid underestimating cervical cancer incidence rates and masking disparities by age, race, and geographic region. |

Mix JM , Miller MJ , Querec TD , Darragh TM , Saraiya M , Gopalani SV , Lynch CF , Thompson TD , Greek A , Tucker TC , Peters ES , Unger ER . J Registry Manag 2023 50 (4) 116-121 INTRODUCTION: Scrotal squamous cell carcinomas (SCCs) are rare malignancies that are not considered to be associated with the human papillomavirus (HPV) by the International Agency for Research on Cancer. However, recent studies have detected HPV in these cancers. We sought to determine the presence of HPV types among scrotal cancer cases identified through population-based cancer registries. METHODS: Primary scrotal SCCs diagnosed from 2014 to 2015 were identified, and tissue sections from formalin-fixed, paraffin-embedded tissue blocks were obtained for laboratory testing. A pathology review was performed to confirm morphology. HPV testing was performed using L1 consensus polymerase chain reaction analysis. Immunohistochemistry was used to evaluate p16INK4a (p16) expression. RESULTS: Five cases of scrotal SCC were identified from 1 cancer registry. Age at diagnosis ranged from 34 to 75 years (median, 56 years). Four cases were non-Hispanic White, and 1 was non-Hispanic Black. The morphologic subtype of 4 cases was keratinizing (usual), and 1 case was verrucous (warty) histologic subtype. Two of the usual cases of SCC were HPV-negative and p16-negative, and 2 were positive for HPV16 and p16. The verrucous (warty) SCC subtype case was HPV6-positive and p16-negative. CONCLUSIONS: The presence of HPV16 and p16 overexpression in the examined tissue specimens lends additional support for the role of HPV in the etiology of scrotal SCC. |
Biological effects of diesel exhaust inhalation. III cardiovascular function
Krajnak K , Kan H , Thompson JA , McKinney W , Waugh S , South T , Burns D , Lebouf R , Cumpston J , Boots T , Fedan JS . Inhal Toxicol 2024 1-16 OBJECTIVE: Inhalation of diesel exhaust (DE) has been shown to be an occupational hazard in the transportation, mining, and gas and oil industries. DE also contributes to air pollution, and therefore, is a health hazard to the general public. Because of its effects on human health, changes have been made to diesel engines to reduce both the amounts of particulate matter and volatile fumes they generate. The goal of the current study was to examine the effects of inhalation of diesel exhaust. MATERIALS AND METHODS: The study presented here specifically examines the effects of exposure to 0.2 and 1.0 mg/m(3) DE or filtered air (6h/d for 4 d) on measures of peripheral and cardio-vascular function, and biomarkers of heart and kidney dysfunction in male rats. A Tier 2 engine used in oil and gas fracking operations was used to generate the diesel exhaust. RESULTS: Exposure to 0.2 mg/m(3) DE resulted in an increase in blood pressure 1d following the last exposure, and increases in dobutamine-induced cardiac output and stroke volume 1 and 27d after exposure. Changes in peripheral vascular responses to norepinephrine and acetylcholine were minimal as were changes in transcript expression in the heart and kidney. Exposure to 1.0 mg/m(3) DE did not result in major changes in blood pressure, measures of cardiac function, peripheral vascular function or transcript expression. DISCUSSION AND CONCLUSIONS: Based on the results of this study, we suggest that exposure to DE generated by a Tier 2 compliant diesel engine generates acute effects on biomarkers indicative of cardiovascular dysfunction. Recovery occurs quickly with most measures of vascular/cardiovascular function returning to baseline levels by 7d following exposure. |
Associations between childhood opportunity index and pediatric cardiac surgical outcomes
Kolwaite AR , Edwards JA , Higgins M , Kandaswamy S , Orenstein E , Boughton D , Zinyandu T , Brasher S , Shashidharan S , Thompson LM , Chanani NK . J Pediatr 2024 114000 OBJECTIVE: To assess the relationship between the Childhood Opportunity Index (COI), a comprehensive measurement of social determinants of health (SDOH), and specific COI domains on patient-specific outcomes following congenital cardiac surgery in the metropolitan region of Atlanta, Georgia. STUDY DESIGN: In this retrospective chart review, we included patients who underwent an index operation for congenital heart disease (CHD) between 2010 and 2020 in a single pediatric health care system. Patients' addresses were geocoded and mapped to census tracts. Descriptive statistics, univariable analysis, and multivariable regression models were employed to assess associations between variables and outcomes. RESULTS: Of the 7460 index surgeries, 3798 (51%) met eligibility criteria. Presence of an adverse outcome, defined as either mortality or one of several other major post-operative morbidities, was significantly associated with COI in the univariable model (p=0.008), but not the multivariable regression model (p=0.39). Postoperative hospital length of stay (PHLOS) was significantly associated with COI (p<0.001) in univariable and multivariable regression models. There was no significant association between COI and readmission within 30 days of hospital discharge in univariable (p<0.094) and multivariable (p=0.49) models. CONCLUSION: COI is associated with PHLOS but not all outcomes in patients after congenital heart surgery. By understanding the role of COI in outcomes related to cardiac surgery, targeted interventions can be developed to improve health equity. |
Nitrate exposure from drinking water and dietary sources among Iowa farmers using private wells
Skalaban TG , Thompson DA , Madrigal JM , Blount BC , Espinosa MM , Kolpin DW , Deziel NC , Jones RR , Freeman LB , Hofmann JN , Ward MH . Sci Total Environ 2024 170922 Nitrate levels are increasing in water resources across the United States and nitrate ingestion from drinking water has been associated with adverse health risks in epidemiologic studies at levels below the maximum contaminant level (MCL). In contrast, dietary nitrate ingestion has generally been associated with beneficial health effects. Few studies have characterized the contribution of both drinking water and dietary sources to nitrate exposure. The Agricultural Health Study is a prospective cohort of farmers and their spouses in Iowa and North Carolina. In 2018-2019, we assessed nitrate exposure for 47 farmers who used private wells for their drinking water and lived in 8 eastern Iowa counties where groundwater is vulnerable to nitrate contamination. Drinking water and dietary intakes were estimated using the National Cancer Institute Automated Self-Administered 24-Hour Dietary Assessment tool. We measured nitrate in tap water and estimated dietary nitrate from a database of food concentrations. Urinary nitrate was measured in first morning void samples in 2018-19 and in archived samples from 2010 to 2017 (minimum time between samples: 2 years; median: 7 years). We used linear regression to evaluate urinary nitrate concentrations in relation to total nitrate, and drinking water and dietary intakes separately. Overall, dietary nitrate contributed the most to total intake (median: 97 %; interquartile range [IQR]: 57-99 %). Among 15 participants (32 %) whose drinking water nitrate concentrations were at/above the U.S. Environmental Protection Agency MCL (10 mg/L NO(3)-N), median intake from water was 44 % (IQR: 26-72 %). Total nitrate intake was the strongest predictor of urinary nitrate concentrations (R(2) = 0.53). Drinking water explained a similar proportion of the variation in nitrate excretion (R(2) = 0.52) as diet (R(2) = 0.47). Our findings demonstrate the importance of both dietary and drinking water intakes as determinants of nitrate excretion. |
Hepatitis C virus testing, infection, and cases reported through public health surveillance during expanded screening recommendations, United States, 2013-2021
Ly KN , Niles JK , Jiles RB , Kaufman HW , Weng MK , Patel P , Meyer WA 3rd , Thompson WW , Thompson ND . Public Health Rep 2024 333549231224199 OBJECTIVES: Hepatitis C virus (HCV) infection is the most common bloodborne infection in the United States. We assessed trends in HCV testing, infection, and surveillance cases among US adults. METHODS: We used Quest Diagnostics data from 2013-2021 to assess trends in the numbers tested for HCV antibody and proportion of positivity for HCV antibody and HCV RNA. We also assessed National Notifiable Diseases Surveillance System 2013-2020 data for trends in the number and proportion of hepatitis C cases. We applied joinpoint regression for trends testing. RESULTS: Annual HCV antibody testing increased from 1.7 million to 4.8 million from 2013 to 2021, and the positivity proportion declined (average, 0.2% per year) from 5.5% to 3.7%. The greatest percentage-point increase in HCV antibody testing occurred in hospitals and substance use disorder treatment facilities and among addiction medicine providers. HCV RNA positivity was stable at about 60% in 2013-2015 and declined to 41.0% in 2021 (2015-2021 average, -3.2% per year). Age-specific HCV RNA positivity was highest among people aged 40-59 years during 2013-2015 and among people aged 18-39 years during 2016-2021. The number of reported hepatitis C cases (acute and chronic) declined from 179 341 in 2015 to 105 504 in 2020 (average decline, -13 177 per year). The proportion of hepatitis C cases among those aged 18-39 years increased by an average of 1.4% per year during 2013-2020; among individuals aged 40-59 years, it decreased by an average of 2.3% per year during 2013-2018. CONCLUSIONS: HCV testing increased, suggesting improved universal screening. Various data sources are valuable for monitoring elimination progress. |

Mol Genet Metab 2014 112 (2) 87-122 New developments in the treatment and management of phenylketonuria (PKU) as well as advances in molecular testing have emerged since the National Institutes of Health 2000 PKU Consensus Statement was released. An NIH State-of-the-Science Conference was convened in 2012 to address new findings, particularly the use of the medication sapropterin to treat some individuals with PKU, and to develop a research agenda. Prior to the 2012 conference, five working groups of experts and public members met over a 1-year period. The working groups addressed the following: long-term outcomes and management across the lifespan; PKU and pregnancy; diet control and management; pharmacologic interventions; and molecular testing, new technologies, and epidemiologic considerations. In a parallel and independent activity, an Evidence-based Practice Center supported by the Agency for Healthcare Research and Quality conducted a systematic review of adjuvant treatments for PKU; its conclusions were presented at the conference. The conference included the findings of the working groups, panel discussions from industry and international perspectives, and presentations on topics such as emerging treatments for PKU, transitioning to adult care, and the U.S. Food and Drug Administration regulatory perspective. Over 85 experts participated in the conference through information gathering and/or as presenters during the conference, and they reached several important conclusions. The most serious neurological impairments in PKU are preventable with current dietary treatment approaches. However, a variety of more subtle physical, cognitive, and behavioral consequences of even well-controlled PKU are now recognized. The best outcomes in maternal PKU occur when blood phenylalanine (Phe) concentrations are maintained between 120 and 360 μmol/L before and during pregnancy. The dietary management treatment goal for individuals with PKU is a blood Phe concentration between 120 and 360 μmol/L. The use of genotype information in the newborn period may yield valuable insights about the severity of the condition for infants diagnosed before maximal Phe levels are achieved. While emerging and established genotype-phenotype correlations may transform our understanding of PKU, establishing correlations with intellectual outcomes is more challenging. Regarding the use of sapropterin in PKU, there are significant gaps in predicting response to treatment; at least half of those with PKU will have either minimal or no response. A coordinated approach to PKU treatment improves long-term outcomes for those with PKU and facilitates the conduct of research to improve diagnosis and treatment. New drugs that are safe, efficacious, and impact a larger proportion of individuals with PKU are needed. However, it is imperative that treatment guidelines and the decision processes for determining access to treatments be tied to a solid evidence base with rigorous standards for robust and consistent data collection. The process that preceded the PKU State-of-the-Science Conference, the conference itself, and the identification of a research agenda have facilitated the development of clinical practice guidelines by professional organizations and serve as a model for other inborn errors of metabolism. |
