RESUMO

Using national pharmacy claims data for 2014-2020, 843 329 persons were treated for hepatitis C at least once. The proportion treated increased annually among persons aged <40 years, insured by Medicaid, and treated by primary care providers. Monitoring hepatitis C treatment is essential to identify barriers to treatment access.

RESUMO

BACKGROUND AND AIMS: In the USA, HBV is one of the leading causes of chronic liver disease and cirrhosis and is a major cause of liver cancer. We aimed to estimate the prevalence of past and present HBV infection, susceptibility to HBV infection, and vaccine-induced immunity to hepatitis B among the US population during 2013-2018. APPROACH AND RESULTS: Prevalence estimates and 95% CIs were analyzed using 2013-2018 data from the National Health and Nutrition Examination Survey. Serologic testing among noninstitutionalized persons aged ≥ 6 years was used for classifying persons as total hepatitis B core antibody (anti-HBc), indicative of current or previous (ever having had) HBV infection; HBsAg, indicative of current HBV infection; and antibody to ABsAg (anti-HBs), indicative of immunity attributable to hepatitis B vaccination. Persons who tested negative for anti-HBc, HBsAg, and anti-HBs were considered susceptible to HBV infection. Non-US-born residents accounted for 69.1% of the population with chronic HBV infection and were 9.1 times more likely to be living with chronic hepatitis B, compared with US-born persons. Among adults aged ≥ 25 years who resided in US households, an estimated 155.8 million persons (or 73.4%) were susceptible to HBV infection, and an estimated 45.4 million had vaccine-induced immunity to hepatitis B. Men who have sex with men (MSM) were 3.6 times more likely to have ever been infected with HBV; however, MSM were just as likely to have vaccine-induced immunity to hepatitis B as non-MSM. CONCLUSION: Despite increasing immune protection among young persons vaccinated after birth, the estimated prevalence of persons living with chronic hepatitis B in the USA has remained unchanged at 0.3% since 1999.

RESUMO

BACKGROUND: Sexual transmission of hepatitis B virus (HBV) is common in the United States. In 2008, an estimated 50% of HBV infections were attributed to sexual transmission. Among 21,600 acute infections that occurred in 2018, the proportion attributable to sexual transmissions is unknown. METHODS: Objectives of this study were to estimate incidence and prevalence of hepatitis B attributable to sexual transmission among the US population 15 years and older for 2013 to 2018. Incidence estimates were calculated for confirmed cases submitted to Centers for Disease Control and Prevention from 14 states. A hierarchical algorithm defining sexually transmitted acute HBV infections as the absence of injection drug use among persons reporting sexual risk factors was applied to determine proportion of hepatitis B infections attributable to sexual transmission nationally. National Health and Nutrition Examination Survey public use data files were analyzed to calculate prevalence estimates of hepatitis B among US households and proportion attributed to sexual transmission was conservatively determined for HBV-infected non-US-born Americans who migrated from HBV endemic countries. RESULTS: During 2013 to 2018, an estimated 47,000 (95% confidence interval [CI], 27,000-116,000) or 38.2% of acute HBV infections in the United States were attributable to sexual transmission. During 2013 to 2018, among the US noninstitutionalized population, an estimated 817,000 (95% CI, 613,000-1,100,000) persons 15 years and older were living with hepatitis B, with an estimated 103,000 (95% CI, 89,000-118,000) infections or 12.6% attributable to sexual transmission. CONCLUSIONS: These findings provide evidence sexually transmitted HBV infections remain a public health problem and underscore the importance of interventions to improve vaccination among at-risk populations.

RESUMO

BACKGROUND: We estimated the lifetime medical costs attributable to sexually transmitted infections (STIs) acquired in 2018, including sexually acquired human immunodeficiency virus (HIV). METHODS: We estimated the lifetime medical costs of infections acquired in 2018 in the United States for 8 STIs: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes, human papillomavirus (HPV), hepatitis B, and HIV. We limited our analysis to lifetime medical costs incurred for treatment of STIs and for treatment of related sequelae; we did not include other costs, such as STI prevention. For each STI, except HPV, we calculated the lifetime medical cost by multiplying the estimated number of incident infections in 2018 by the estimated lifetime cost per infection. For HPV, we calculated the lifetime cost based on the projected lifetime incidence of health outcomes attributed to HPV infections acquired in 2018. Future costs were discounted at 3% annually. RESULTS: Incident STIs in 2018 imposed an estimated $15.9 billion (25th-75th percentile: $14.9-16.9 billion) in discounted, lifetime direct medical costs (2019 US dollars). Most of this cost was due to sexually acquired HIV ($13.7 billion) and HPV ($0.8 billion). STIs in women accounted for about one fourth of the cost of incident STIs when including HIV, but about three fourths when excluding HIV. STIs among 15- to 24-year-olds accounted for $4.2 billion (26%) of the cost of incident STIs. CONCLUSIONS: Incident STIs continue to impose a considerable lifetime medical cost burden in the United States. These results can inform health economic analyses to promote the use of cost-effective STI prevention interventions to reduce this burden.

RESUMO

BACKGROUND: The most recent estimates of the number of prevalent and incident sexually transmitted infections (STIs) in the United States were for 2008. We provide updated estimates for 2018 using new methods. METHODS: We estimated the total number of prevalent and incident infections in the United States for 8 STIs: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes, human papillomavirus, sexually transmitted hepatitis B, and sexually transmitted HIV. Updated per-capita prevalence and incidence estimates for each STI were multiplied by the 2018 full resident population estimates to calculate the number of prevalent and incident infections. STI-specific estimates were combined to generate estimates of the total number of prevalent and incident STIs overall, and by sex and age group. Primary estimates are represented by medians, and uncertainty intervals are represented by the 25th (Q1) and 75th (Q3) percentiles of the empirical frequency distributions of prevalence and incidence for each STI. RESULTS: In 2018, there were an estimated 67.6 (Q1, 66.6; Q3, 68.7) million prevalent and 26.2 (Q1, 24.0; Q3, 28.7) million incident STIs in the United States. Chlamydia, trichomoniasis, genital herpes, and human papillomavirus comprised 97.6% of all prevalent and 93.1% of all incident STIs. Persons aged 15 to 24 years comprised 18.6% (12.6 million) of all prevalent infections; however, they comprised 45.5% (11.9 million) of all incident infections. CONCLUSIONS: The burden of STIs in the United States is high. Almost half of incident STIs occurred in persons aged 15 to 24 years in 2018. Focusing on this population should be considered essential for national STI prevention efforts.

RESUMO

BACKGROUND: Mortality associated with hepatitis C virus (HCV) has been well-documented nationally, but an examination across regions and jurisdictions may inform health-care planning. METHODS: To document HCV-associated deaths sub-nationally, we calculated age-adjusted, HCV-associated death rates and compared death rate ratios (DRRs) for 10 US regions, 50 states, and Washington, D.C., using the national rate and described rate changes between 2016 and 2017 to determine variability. We examined the mean age at HCV-associated death, and rates and proportions by sex, race/ethnicity, and birth year. RESULTS: In 2017, there were 17 253 HCV-associated deaths, representing 4.13 (95% confidence interval [CI], 4.07-4.20) deaths/100 000 standard population, in a significant, 6.56% rate decline from 4.42 in 2016. Age-adjusted death rates significantly surpassed the US rate for the following jurisdictions: Oklahoma; Washington, D.C.; Oregon; New Mexico; Louisiana; Texas; Colorado; California; Kentucky; Tennessee; Arizona; and Washington (DRRs, 2.87, 2.77, 2.24, 1.62, 1.57, 1.46, 1.36, 1.35, 1.35, 1.35, 1.32, and 1.32, respectively; P < .05). Death rates ranged from a low of 1.60 (95% CI, 1.07-2.29) in Maine to a high of 11.84 (95% CI, 10.82-12.85) in Oklahoma. Death rates were highest among non-Hispanic (non-H) American Indians/Alaska Natives and non-H Blacks, both nationally and regionally. The mean age at death was 61.4 years (range, 56.6 years in West Virginia to 64.1 years in Washington, D.C.), and 78.6% of those who died were born during 1945-1965. CONCLUSIONS: In 2016-2017, the national HCV-associated mortality declined but rates remained high in the Western and Southern regions and Washington, D.C., and among non-H American Indians/Alaska Natives, non-H Blacks, and Baby Boomers. These data can inform local prevention and control programs to reduce the HCV mortality burden.

RESUMO

BACKGROUND: Pyoderma gangrenosum (PG) is an uncommon but severe extra-intestinal manifestation (EIM) of inflammatory bowel disease (IBD). The incidence and risk factors for PG are disputed. AIMS: To assess the incidence of PG and identify factors associated with PG in IBD patients. METHODS: A search of electronic databases (Ovid and PubMed) was conducted between 1966 and 2019. Studies that calculated the incidence of PG in IBD patient cohorts were included. Patient demographics, IBD subtype, and EIM presence were recorded. A review of our institutional database of 1057 IBD patients was conducted. A multivariate regression model and meta-analysis were conducted to identify risk factors for PG. A random effects model was used to combine the data of included studies. RESULTS: Fourteen studies were included in addition to 1057 IBD patients and 26 PG cases from the Louisville cohort. In total, there were 379 cases of PG in the cumulative cohort of 61,695 IBD patients. The PG incidence in individual studies ranged from 0.4 to 2.6%. In the institutional cohort, ocular EIMs and a permanent stoma were significant risk factors for PG. In the meta-analysis, PG was associated with female gender (RR = 1.328, 95% CI 1.161-1.520), Crohn's disease (RR = 1.193, 95% CI 1.001-1.422), erythema nodosum (RR = 9.281, 95% CI 6.081-14.164), and ocular EIM (RR = 4.55, 95% CI 3.04-6.81). There was study heterogeneity when assessing IBD subtype, ocular, and joint EIMs. CONCLUSIONS: There are conflicting data on the incidence and risk factors for PG. This meta-analysis confirms an association between PG and female gender, Crohn's disease, erythema nodosum, and ocular EIM that have been described in smaller studies.

RESUMO

UNLABELLED: The number of persons with chronic hepatitis B virus (HBV) infection in the United States is affected by diminishing numbers of young persons who are susceptible because of universal infant vaccination since 1991, offset by numbers of HBV-infected persons migrating to the United States from endemic countries. The prevalence of HBV infection was determined by serological testing and analysis among noninstitutionalized persons age 6 years and older for: antibody to hepatitis B core antigen (anti-HBc), indicative of previous HBV infection; hepatitis B surface antigen (HBsAg), indicative of chronic (current) infection; and antibody to hepatitis B surface antigen (anti-HBs), indicative of immunity from vaccination. These prevalence estimates were analyzed in three periods of the National Health and Nutrition Examination Survey (NHANES): 1988-1994 (21,260 persons); 1999-2008 (29,828); and 2007-2012 (22,358). In 2011-2012, for the first time, non-Hispanic Asians were oversampled in NHANES. For the most recent period (2007-2012), 3.9% had anti-HBc, indicating approximately 10.8 (95% confidence interval [CI]: 9.4-12.2) million noninstitutionalized U.S. residents having ever been infected with HBV. The overall prevalence of chronic HBV infection has remained constant since 1999: 0.3% (95% CI: 0.2-0.4), and since 1999, prevalence of chronic HBV infection among non-Hispanic blacks has been 2- to 3-fold greater than the general population. An estimated 3.1% (1.8%-5.2%) of non-Hispanic Asians were chronically infected with HBV during 2011-2012, which reflects a 10-fold greater prevalence than the general population. Adjusted prevalence of vaccine-induced immunity increased 16% since 1999, and the number of persons (mainly young) with serological evidence of vaccine protection from HBV infection rose from 57.8 (95% CI: 55.4-60.1) million to 68.5 (95% CI: 65.4-71.2) million. CONCLUSION: Despite increasing immune protection in young persons vaccinated in infancy, an analysis of chronic hepatitis B prevalence in racial and ethnic populations indicates that during 2011-2012, there were 847,000 HBV infections (which included ~400,000 non-Hispanic Asians) in the noninstitutionalized U.S. POPULATION.

RESUMO

BACKGROUND: The organ procurement network recommends a surgeon record 15 cases as surgeon or assistant for laparoscopic donor nephrectomies (LDN) prior to independent practice. The literature suggests that the learning curve for improved perioperative and patient outcomes is closer to 35 cases. In this article, we describe our development of a model utilizing fresh tissue and objective, quantifiable endpoints to document surgical progress, and efficiency in each of the major steps involved in LDN. MATERIALS AND METHODS: Phase I of model development focused on the modifications necessary to maintain visualization for laparoscopic surgery in a human cadaver. Phase II tested proposed learner-based metrics of procedural competency for multiport LDN by timing procedural steps of LDN in a novice learner. RESULTS: Phases I and II required 12 and nine cadavers, with a total of 35 kidneys utilized. The following metrics improved with trial number for multiport LDN: time taken for dissection of the gonadal vein, ureter, renal hilum, adrenal and lumbrical veins, simulated warm ischemic time (WIT), and operative time. CONCLUSION: Human cadavers can be used for training in LDN as evidenced by improvements in timed learner-based metrics. This simulation-based model fills a gap in available training options for surgeons.

RESUMO

OBJECTIVE: To develop a plasma-based microRNA (miRNA) diagnostic assay specific for colorectal neoplasms, building upon our prior work. BACKGROUND: Colorectal neoplasms [colorectal cancer (CRC) and colorectal advanced adenoma (CAA)] frequently develop in individuals at ages when other common cancers also occur. Current screening methods lack sensitivity, specificity, and have poor patient compliance. METHODS: Plasma was screened for 380 miRNAs using microfluidic array technology from a "Training" cohort of 60 patients, (10 each) control, CRC, CAA, breast cancer, pancreatic cancer, and lung cancer. We identified uniquely dysregulated miRNAs specific for colorectal neoplasia (P < 0.05, false discovery rate: 5%, adjusted α = 0.0038). These miRNAs were evaluated using single assays in a "Test" cohort of 120 patients. A mathematical model was developed to predict blinded sample identity in a 150 patient "Validation" cohort using repeat-sub-sampling validation of the testing dataset with 1000 iterations each to assess model detection accuracy. RESULTS: Seven miRNAs (miR-21, miR-29c, miR-122, miR-192, miR-346, miR-372, and miR-374a) were selected based upon P value, area under the curve (AUC), fold change, and biological plausibility. Area under the curve (±95% confidence interval) for "Test" cohort comparisons were 0.91 (0.85-0.96) between all neoplasia and controls, 0.79 (0.70-0.88) between colorectal neoplasia and other cancers, and 0.98 (0.96-1.0) between CRC and colorectal adenomas. In our "Validation" cohort, our mathematical model predicted blinded sample identity with 69% to 77% accuracy, 67% to 76% accuracy, and 86% to 90% accuracy for each comparison, respectively. CONCLUSIONS: Our plasma miRNA assay and prediction model differentiate colorectal neoplasia from patients with other neoplasms and from controls with higher sensitivity and specificity compared with current clinical standards.

RESUMO

BACKGROUND: An estimated 20 000 new hepatitis B virus (HBV) infections occur each year in the United States. We describe the results of enhanced surveillance for acute hepatitis B at 7 federally funded sites over a 6-year period. METHODS: Health departments in Colorado, Connecticut, Minnesota, Oregon, Tennessee, 34 counties in New York state, and New York City were supported to conduct enhanced, population-based surveillance for acute HBV from 2006 through 2011. Demographic and risk factor data were collected on symptomatic cases using a standardized form. Serum samples from a subset of cases were also obtained for molecular analysis. RESULTS: In the 6-year period, 2220 acute hepatitis B cases were reported from the 7 sites. For all sites combined, the incidence rate of HBV infection declined by 19%, but in Tennessee incidence increased by 90%, mainly among persons of white race/ethnicity and those aged 40-49 years. Of all reported cases, 66.1% were male, 57.1% were white, 58.4% were aged 30-49 years, and 60.1% were born in the United States. The most common risk factor identified was any drug use, notably in Tennessee; healthcare exposure was also frequently reported. The most common genotype for all reported cases was HBV genotype A (82%). CONCLUSIONS: Despite an overall decline in HBV infection, attributable to successful vaccination programs, a rise in incident HBV infection related to drug use is an increasing concern in some localities.

RESUMO

Therapeutic hypothermia is commonly used to improve neurological outcomes in patients after cardiac arrest. However, therapeutic hypothermia increases sepsis risk and unintentional hypothermia in surgical patients increases infectious complications. Nonetheless, the molecular mechanisms by which hypothermia dysregulates innate immunity are incompletely understood. We found that exposure of human monocytes to cold (32°C) potentiated LPS-induced production of TNF and IL-6, while blunting IL-10 production. This dysregulation was associated with increased expression of microRNA-155 (miR-155), which potentiates Toll-like receptor (TLR) signaling by negatively regulating Ship1 and Socs1. Indeed, Ship1 and Socs1 were suppressed at 32°C and miR-155 antagomirs increased Ship1 and Socs1 and reversed the alterations in cytokine production in cold-exposed monocytes. In contrast, miR-155 mimics phenocopied the effects of cold exposure, reducing Ship1 and Socs1 and altering TNF and IL-10 production. In a murine model of LPS-induced peritonitis, cold exposure potentiated hypothermia and decreased survival (10 vs. 50%; P < 0.05), effects that were associated with increased miR-155, suppression of Ship1 and Socs1, and alterations in TNF and IL-10. Importantly, miR-155-deficiency reduced hypothermia and improved survival (78 vs. 32%, P < 0.05), which was associated with increased Ship1, Socs1, and IL-10. These results establish a causal role of miR-155 in the dysregulation of the inflammatory response to hypothermia.

RESUMO

CONTEXT: Employee performance evaluation motivates and rewards exceptional individual performance that advances the achievement of organizational goals. The Centers for Disease Control and Prevention (CDC) and its operating units evaluate employee performance annually and reward exceptional performance with a cash award or quality step increase in pay. A summary performance rating (SPR) of "exceptional" indicated personal achievements in 2011 that were beyond expectations described in the employee's performance plan. OBJECTIVE: To determine whether personal attributes and job setting of civil service employees were associated with an exceptional SPR in National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) in 2011. DESIGN: Data from the CDC 2011 performance management database collected in 2012 were analyzed in 2013 to identify SPR, personal attributes, and job settings of full-time civil service employees. Multivariate logistic regression controlled for confounding and stratified analysis detected effect modifiers of the association between receiving an exceptional SPR in 2011 and gender, race/ethnicity, education, job location, job series, grade level, years in grade, years of federal service, supervisory role, and NCHHSTP division. RESULTS: Among the 1037 employees, exceptional SPR was independently associated with: female gender (adjusted odds ratio: 1.7 [1.3, 2.3]), advanced degrees (doctorate: 1.7 [1.1, 2.5] master's: [1.1, 2.0]), headquarters location (2.8 [1.9, 4.1]), higher pay grade (3.3 [2.4, 4.5]) and years in grade (0-1 years: 1.7 [1.3, 2.4]; 2-4 years: 1.5 [1.1, 2.0]), division level (Division A: 5.0 [2.5, 9.9]; Division B: 5.5 [3.5, 8.8]), and supervisory status (at a lower-pay grade) (odds ratio: 3.7 [1.1, 11.3]). CONCLUSIONS: Exceptional SPR is independently associated with personal employee attributes and job settings that are not modifiable by interventions designed to improve employee performance based on accomplishments.

RESUMO

OBJECTIVES: Chronic liver disease (CLD) is increasingly recognized as a major public health problem. However, in the United States, there are few nationally representative data on the contribution of viral hepatitis as an etiology of CLD. METHODS: We applied a previously used International Classification of Diseases, Ninth Revision, Clinical Modification-based definition of CLD cases to the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey databases for 2006-2010. We estimated the mean number of CLD visits per year, prevalence ratio of visits by patient characteristics, and the percentage of CLD visits attributed to viral hepatitis and other selected etiologies. RESULTS: An estimated 6.0 billion ambulatory care visits occurred in the United States from 2006 to 2010, of which an estimated 25.8 million (0.43%) were CLD-related. Among adults aged 45-64 years, Medicaid and Medicare recipients were 3.9 (prevalence ratio (PR)=3.9, 95% confidence limit (CL; 2.8, 5.4)) and 2.3 (PR=2.3, 95% CL (1.6, 3.4)) times more likely to have a CLD-related ambulatory visit than those with private insurance, respectively. In the United States, from 2006 to 2010, an estimated 49.6% of all CLD-related ambulatory visits were attributed solely to viral hepatitis B and C diagnoses. CONCLUSIONS: In this unique application of health-care utilization data, we confirm that viral hepatitis is an important etiology of CLD in the United States, with hepatitis B and C contributing approximately one-half of the CLD burden. CLD ambulatory visits in the United States disproportionately occur among adults, aged 45-64 years, who are primarily minorities, men, and Medicare or Medicaid recipients.

RESUMO

OBJECTIVES: Because only a fraction of patients with acute viral hepatitis A, B, and C are reported through national surveillance to the Centers for Disease Control and Prevention, we estimated the true numbers. METHODS: We applied a simple probabilistic model to estimate the fraction of patients with acute hepatitis A, hepatitis B, and hepatitis C who would have been symptomatic, would have sought health care tests, and would have been reported to health officials in 2011. RESULTS: For hepatitis A, the frequencies of symptoms (85%), care seeking (88%), and reporting (69%) yielded an estimate of 2730 infections (2.0 infections per reported case). For hepatitis B, the frequencies of symptoms (39%), care seeking (88%), and reporting (45%) indicated 18 730 infections (6.5 infections per reported case). For hepatitis C, the frequency of symptoms among injection drug users (13%) and those infected otherwise (48%), proportion seeking care (88%), and percentage reported (53%) indicated 17 100 infections (12.3 infections per reported case). CONCLUSIONS: These adjustment factors will allow state and local health authorities to estimate acute hepatitis infections locally and plan prevention activities accordingly.

RESUMO

AIMS: To define the number/frequency of organ systems affected by extraintestinal manifestations (EIMs), to identify factors affecting the clinical course of inflammatory bowel disease (IBD) and EIM development, and to determine the impact of smoking, disease duration and location on the diagnosis of EIMs in Crohn's disease (CD) and ulcerative colitis (UC). METHODS: IBD patients were derived from a single university colorectal surgery practice. Smoking data were obtained through a modified Behavioral Risk Factor Surveillance System survey. The frequencies of arthritis/arthralgia, primary sclerosing cholangitis (PSC), ocular and cutaneous EIMs were determined. RESULTS: Of the 757 patients evaluated (CD 488, UC 269), 50% had ≥1 EIM. Arthritis/arthralgia, cutaneous and ocular EIMs were significantly higher in frequency in CD compared to UC patients. Prolonged disease duration was associated with increased prevalence of arthritis/arthralgia in IBD (p ≤ 0.001) as well as PSC (p = 0.049), ocular (p = 0.030) and cutaneous (p = 0.009) EIMs in CD. Disease location affected the occurrence of EIMs in CD. Smoking appeared to increase the prevalence of ocular EIMs in UC (p = 0.026). CONCLUSION: Arthritis/arthralgia, cutaneous and ocular EIMs occurred in a significantly higher proportion of CD patients. CD patients with longer disease duration had a significantly higher prevalence of PSC, ocular and cutaneous EIMs. Smoking was found to increase ocular EIMs in UC.

RESUMO

OBJECTIVE: The main objective of this study was to investigate the potential use of circulating microRNAs (miRNAs) as biomarkers of colorectal (CR) adenomas. BACKGROUND: Detection of precancerous lesions such as CR adenoma is a key to reduce CR cancer (CRC) mortality. There is a great need for accurate, noninvasive biomarkers for detection of CR adenoma and CRC. MiRNAs are non-protein-coding RNAs that regulate gene expression. Our prior work investigated the dysregulation of 5 plasma miRNAs in CRC patients. As intended, we undertook a more comprehensive plasma-miRNA screening study in patients with CR adenoma and CRC. METHODS: We screened for 380 plasma-miRNAs using microfluidic array technology (Applied BioSystems) in a screening cohort of 12 healthy controls, 9 patients with CR adenomas, and 20 patients with CRC. A panel of the most dysregulated miRNAs (P < 0.05, False Discovery Rate: 5%) was then validated in a blinded cohort of 26 healthy controls, 16 patients with large adenomas, and 45 patients with CRC. RESULTS: A panel of 8 plasma miRNAs (miR-532-3p, miR-331, miR-195, miR-17, miR-142-3p, miR-15b, miR-532, and miR-652) distinguished polyps from controls with high accuracy [area under curve (AUC) = 0.868 (95% confidence interval [CI]: 0.76-0.98)]. In addition, a panel of 3 plasma miRNAs (miR-431, miR-15b, and miR-139-3p) distinguished Stage IV CRC from controls with an [AUC = 0.896 (95% CI: 0.78-1.0)]. Receiver-operating-characteristic curves of miRNA panels for all CRC versus controls and polyps versus all CRC showed AUC values of 0.829 (95% CI: 0.73-0.93) and 0.856 (95% CI: 0.75-0.97), respectively. CONCLUSIONS: Plasma miRNAs are reliable, noninvasive, and inexpensive markers for CR adenomas. This miRNA panel warrants study in larger cohorts. Plasma-based assays could provide better screening compliance compared to fecal occult blood or endoscopic screening.

RESUMO

Estimates of the prevalence of chronic hepatitis B (CHB) in the United States differ significantly, and the contribution of foreign-born (FB) persons has not been adequately described. The aim of this study was to estimate the number of FB persons in the United States living with CHB by their country of origin. We performed a systematic review for reports of HBsAg seroprevalence rates in 102 countries (covering PubMed from 1980 to July 2010). Data from 1,373 articles meeting inclusion criteria were extracted into country-specific databases. We identified 256 seroprevalence surveys in emigrants from 52 countries (including 689,078 persons) and 1,797 surveys in the general populations of 98 countries (including 17,861,035 persons). Surveys including individuals with lower or higher risk of CHB than the general population were excluded. Data were combined using meta-analytic methods to determine country-specific pooled CHB prevalence rates. Rates were multiplied by the number of FB living in the United States in 2009 by country of birth from the U.S. Census Bureau to yield the number of FB with CHB from each country. We estimate a total of 1.32 million (95% confidence interval: 1.04-1.61) FB in the United States living with CHB in 2009; 58% migrated from Asia and 11% migrated from Africa, where hepatitis B is highly endemic. Approximately 7% migrated from Central America, a region with lower CHB rates, but many more emigrants to the United States. This analysis suggests that the number of FB persons living with CHB in the United States may be significantly greater than previously reported. Assuming 300,000-600,000 U.S.-born persons with CHB, the total prevalence of CHB in the United States may be as high as 2.2 million.

RESUMO

During 1990-2019, universal infant and childhood vaccination for hepatitis B resulted in a 99% decline in reported cases of acute hepatitis B among children, adolescents, and young adults aged <19 years in the United States; however, during 2010-2019, cases of acute hepatitis B plateaued or increased among adults aged ≥40 years. We conducted a topical review of surveillance strategies that will be critical to support the elimination of hepatitis B as a public health threat in the United States. In 2019, notifiable disease surveillance for acute hepatitis B showed continued transmission, especially among people who inject drugs and people with multiple sexual partners; rates were highest among people who were aged 30-59 years, non-Hispanic White, and living in rural areas. In contrast, newly reported cases of chronic hepatitis B (CHB) were highest among people who were aged 30-49 years, Asian or Pacific Islander, and living in urban areas. The National Health and Nutrition Examination Survey documented the highest CHB prevalence among non-US-born, non-Hispanic Asian people during 2013-2018; only one-third of people with CHB were aware of their infection. In the context of universal adult vaccination (2022) and screening (2023) recommendations for hepatitis B, better data are needed to support programmatic strategies to improve (1) vaccination rates among people with behaviors that put them at risk for transmission and (2) screening and linkage to care among non-US-born people. Surveillance for hepatitis B needs to be strengthened throughout the health care and public health systems.

RESUMO

The overlapping epidemics of hepatitis C virus (HCV) and HIV infection stem from underlying behaviors and health disparities among disproportionately affected populations, especially people who inject drugs (PWID). Characterizing the prevalence of HCV-HIV coinfection offers improved data to address these underlying determinants of health. We performed a literature search for articles that describe US populations, were published during 2005-2021, and summarized evidence of the prevalence of HCV infection in recent HIV clusters and outbreaks among PWID. In population- and community-based studies, HCV antibody prevalence among PWID with HIV ranged from 10.7% to 71.4%, depending on the setting and study design. HCV-HIV coinfection ranged from 70% to 94% among 5 larger HIV clusters or outbreaks among PWID during 2014-2021; where characterized, HCV diagnosis preceded HIV detection by a median of 4 to 5 years. Robust modernized surveillance is needed to support and measure the progress of city, state, and national activities for ending the HIV epidemic and eliminating hepatitis C. Developing and leveraging surveillance systems can identify missed opportunities for prevention, evaluate care, and build capacity for outbreak investigation. In addition, improved data on injection drug use are crucial to inform efforts for improved HCV and HIV testing, prevention, and treatment in settings that serve PWID. By providing data in a wholistic, integrated manner, public health surveillance programs can support efforts to overcome inefficiencies of disease-specific silos, accelerate delivery of preventive and clinical services, and address the excess disease burden and health disparities associated with HCV-HIV coinfection.
