Voluntary medical male circumcision among adolescents: a missed opportunity for Hiv behavioral interventions

Objective: Voluntary medical male circumcision (VMMC) is one of the first opportunities for adolescent males in African countries to interact with the healthcare system. This study explored the approaches used during adolescent VMMC counseling and whether these strategies maximize broader HIV prevention opportunities. Methods: Qualitative interviews were conducted with 92 VMMC clients ages 10–19 years in South Africa (nu200a=u200a36), Tanzania (nu200a=u200a36), and Zimbabwe (nu200a=u200a20) and 33 VMMC providers across the three countries. Discussions explored HIV prevention counseling, testing, and disclosure of results. Audio recordings were transcribed, translated into English, and coded thematically by two individuals. Results: Male adolescents in all three countries reported that limited information was provided about HIV prevention and care, and adolescents were rarely provided condoms. Although VMMC protocols require opt-out HIV testing, adolescents recounted having blood taken without knowing the purpose, not receiving results, nor completely understanding the link between VMMC and HIV. Most males interviewed assumed they had tested negative because they were subsequently circumcised without knowing test results. Providers reported spending little time talking about HIV prevention, including condom use. They admitted that younger adolescent clients often receive little information if assumed they are not sexually active or too young to understand and instead discussed nonsexually transmitted routes of HIV. Conclusion: In the sites of the three countries studied, HIV prevention and care messages were inconsistent and sometimes totally absent from VMMC counseling sessions. VMMC appears to be a missed opportunity to engage in further HIV prevention and care with adolescents.

Use of Hepatitis C Virus (HCV) Immunoglobulin G Antibody Avidity as a Biomarker to Estimate the Population-Level Incidence of HCV Infection

BACKGROUNDnSensitive methods are needed to estimate the population-level incidence of hepatitis C virus (HCV) infection.nnnMETHODSnWe developed an HCV immunoglobulin G (IgG) antibody avidity assay by modifying the Ortho 3.0 HCV enzyme-linked immunoassay and tested 997 serum or plasma samples from 568 people who inject drugs enrolled in prospective cohort studies. Avidity-based testing algorithms were evaluated by their (1) mean duration of recent infection (MDRI), defined as the average time an individual is identified as having been recently infected, according to a given algorithm; (2) false-recent rate, defined as the proportion of samples collected >2 years after HCV seroconversion that were misclassified as recent; (3) sample sizes needed to estimate incidence; and (4) power to detect a reduction in incidence between serial cross-sectional surveys.nnnRESULTSnA multiassay algorithm (defined as an avidity index of <30%, followed by HCV viremia detection) had an MDRI of 147 days (95% confidence interval [CI], 125-195 days), and the false-recent rates were 0.7% (95% CI, .2%-1.8%) and 7.6% (95% CI, 4.2%-12.3%) among human immunodeficiency virus (HIV)-negative and HIV-positive persons, respectively. In various simulated high-risk populations, this algorithm required <1000 individuals to estimate incidence (relative standard error, 30%) and had >80% power to detect a 50% reduction in incidence.nnnCONCLUSIONSnAvidity-based algorithms have the capacity to accurately estimate HCV infection incidence and rapidly assess the impact of public health efforts among high-risk populations. Efforts to optimize this method should be prioritized.

Concordance of Penile and Oral Human Papillomavirus Infections Among Men in the United States

This study examined the concordance of penile and oral human papillomavirus (HPV) infections in the United States. A total of 1683 men aged 18-59 years who participated in the 2013-2014 National Health and Nutrition Examination Survey and had results of oral and penile HPV DNA testing were examined. The prevalence of any HPV genotype was 45.3% on the penis, 11.2% in the oral cavity, and 8.8% at both sites. The prevalence of HPV in the oral cavity was higher among those with than among those without penile HPV infection (19.3% vs 4.4%; prevalence ratio, 4.37 [95% confidence interval, 2.66-7.16]). The prevalence of ≥1 genotype-concordant HPV infection was 3.2% and was associated with sexual behavior, independent of demographic characteristics and smoking status. Sexual behavior may partly explain the observed association between penile and oral HPV infections.

Prevalence and Correlates of Trichomonas vaginalis Infection Among Men and Women in the United States

BackgroundnThe epidemiology of Trichomonas vaginalis (TV) infection in the United States is poorly defined.nnnMethodsnMales and females aged 18-59 years who participated in the 2013-2014 National Health and Nutrition Examination Survey and provided a urine specimen were tested for TV infection (n = 4057). Participants were also examined for Chlamydia trachomatis (CT) infection, genital human papillomavirus (HPV) infection, and herpes simplex virus type 2 serostatus. Weighted adjusted prevalence ratios (aPRs) were estimated by multivariable Poisson regression.nnnResultsnTV infection prevalence was 0.5% and 1.8% among males and females, respectively. TV infection prevalence was 4.2% among black males, 8.9% among black females, and 0.03% and 0.8%, respectively, among males and females of other races/ethnicities. TV infection prevalence (aPR [95% confidence interval]) was positively associated with female sex (6.1 [3.3-11.3]), black race (vs other races/ethnicities; 7.9 [3.9-16.1]), older age (vs 18-24 years; 3.0 [1.2-7.1] for 25- to 39-year-olds and 3.5 [1.3-9.4] for 40- to 59-year-olds), having less than a high school education (vs completing high school or more; 2.0 [1.0-4.1]), being below the poverty level (vs at or above the poverty level; 4.0 [2.1-7.7]), and having ≥2 sexual partners in the past year (vs 0-1 sexual partners; 3.6 [2.0-6.6]). There were no TV and CT coinfections. Genital HPV detection was not independently associated with TV infection. Among persons aged 18-39 years, there was a significant racial disparity in all sexually transmitted infections examined, and this disparity was greatest for TV infection.nnnConclusionsnThere is a high and disproportionate burden of urinary TV infection in the adult civilian, noninstitutionalized black population in the United States that warrants intervention.

Adolescent Wound-Care Self-Efficacy and Practices After Voluntary Medical Male Circumcision—A Multicountry Assessment

Abstract Background Adolescent boys (aged 10–19 years) constitute the majority of voluntary medical male circumcision (VMMC) clients in sub-Saharan Africa. They are at higher risk of postoperative infections compared to adults. We explored adolescents’ wound-care knowledge, self-efficacy, and practices after VMMC to inform strategies for reducing the risks of infectious complications postoperatively. Methods Quantitative and qualitative data were collected in South Africa, Tanzania, and Zimbabwe between June 2015 to September 2016. A postprocedure survey was conducted approximately 7–10 days after VMMC among male adolescents (n = 1293) who had completed a preprocedure survey; the postprocedure survey assessed knowledge of proper wound care and wound-care self-efficacy. We also conducted in-depth interviews (n = 92) with male adolescents 6–10 weeks after the VMMC procedure to further explore comprehension of providers’ wound-care instructions as well as wound-care practices, and we held 24 focus group discussions with randomly selected parents/guardians of the adolescents. Results Adolescent VMMC clients face multiple challenges with postcircumcision wound care owing to factors such as forgetting, misinterpreting, and disregarding provider instructions. Although younger adolescents stated that parental intervention helped them overcome potential hindrances to wound care, parents and guardians lacked crucial information on wound care because most had not attended counseling sessions. Some older adolescents reported ignoring symptoms of infection and not returning to the clinic for review when an adverse event had occurred. Conclusions Increased involvement of parents/guardians in wound-care counseling for younger adolescents and in wound-care supervision, alongside the development of age-appropriate materials on wound care, are needed to minimize postoperative complications after VMMC.

Blood Product Utilization Among Trauma and Nontrauma Massive Transfusion Protocols at an Urban Academic Medical Center

BACKGROUND: Hospital-wide massive transfusion protocols (MTPs) primarily designed for trauma patients may lead to excess blood products being prepared for nontrauma patients. This study characterized blood product utilization among distinct trauma and nontrauma MTPs at a large, urban academic medical center. METHODS: A retrospective study of blood product utilization was conducted in patients who required an MTP activation between January 2011 and December 2015 at an urban academic medical center. Trauma MTP containers included 6 red blood cell (RBC) units, 5 plasma units, and 1 unit of apheresis platelets. Nontrauma MTP containers included 6 RBC and 3 plasma units. RESULTS: There were 334 trauma MTP activations, 233 nontrauma MTP activations, and 77 nontrauma MTP activations that subsequently switched to a trauma MTP (“switched activations”). All nontrauma MTP activations were among bleeding patients who did not have a traumatic injury (100% [233/233]). Few patients with a nontrauma activation required ad hoc transfusion of RBC units (1.3% [95% confidence interval {CI}, 0.3%–3.7%]) or plasma (3.4% [95% CI, 1.5%–6.7%]), and only 45.5% (95% CI, 39.0%–52.1%) required ad hoc transfusion of apheresis platelets. Compared to trauma and switched activations, nontrauma activations transfused a lower median number of RBC, plasma, and apheresis platelet units (P < .001 for all comparisons). There was also a lower median number of prepared but unused plasma units for nontrauma activations (3; [interquartile range {IQR}, 3–5]) compared to trauma (7; [IQR, 5–10]; P < .001) and switched activations (8; [IQR, 5–11]; P < .001). The median number of unused apheresis platelet units was 1 (IQR, 1–2) for trauma activations and 0 (IQR, 0–1) for switched activations. There was a high proportion of trauma and switched activations in which all of the prepared apheresis platelet units were unused (28.1% [95% CI, 23.4%–33.3%] and 9.1% [95% CI, 3.7%–17.8%], respectively). CONCLUSIONS: The majority of initial nontrauma MTP activations did not require a switch to a trauma MTP. Patients remaining under a nontrauma MTP activation were associated with a lower number of transfused and unused plasma and apheresis platelet units. Future studies evaluating the use of hospital-wide nontrauma MTPs are warranted since an MTP designed for nontrauma patient populations may yield a key strategy to optimize blood product utilization in comparison to a universal MTP for both trauma and nontrauma patients.

Association of Perioperative Red Blood Cell Transfusions With Venous Thromboembolism in a North American Registry

Importance Increasing evidence supports the role of red blood cells (RBCs) in physiological hemostasis and pathologic thrombosis. Red blood cells are commonly transfused in the perioperative period; however, their association with postoperative thrombotic events remains unclear. Objective To examine the association between perioperative RBC transfusions and postoperative venous thromboembolism (VTE) within 30 days of surgery. Design, Setting, and Participants This analysis used prospectively collected registry data from the American College of Surgery National Surgical Quality Improvement Program (ACS-NSQIP) database, a validated registry of 525 teaching and nonteaching hospitals in North America. Participants included patients in the ACS-NSQIP registry who underwent a surgical procedure from January 1 through December 31, 2014. Data were analyzed from July 1, 2016, through March 15, 2018. Main Outcomes and Measures Risk-adjusted odds ratios (aORs) were estimated using multivariable logistic regression. The primary outcome was the development of postoperative VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) within 30 days of surgery that warranted therapeutic intervention; DVT and PE were also examined separately as secondary outcomes. Subgroup analyses were performed by surgical subtypes. Propensity score matching was performed for sensitivity analyses. Results Of 750 937 patients (56.8% women; median age, 58 years; interquartile range, 44-69 years), 47 410 (6.3%) received at least 1 perioperative RBC transfusion. Postoperative VTE occurred in 6309 patients (0.8%) (DVT in 4336 [0.6%]; PE in 2514 [0.3%]; both DVT and PE in 541 [0.1%]). Perioperative RBC transfusion was associated with higher odds of VTE (aOR,u20092.1; 95% CI, 2.0-2.3), DVT (aOR,u20092.2; 95% CI, 2.1-2.4), and PE (aOR,u20091.9; 95% CI, 1.7-2.1), independent of various putative risk factors. A significant dose-response effect was observed with increased odds of VTE as the number of intraoperative and/or postoperative RBC transfusion events increased (aOR,u20092.1 [95% CI, 2.0-2.3] for 1 event; 3.1 [95% CI, 1.7-5.7] for 2 events; and 4.5 [95% CI, 1.0-19.4] for ≥3 events vs no intraoperative or postoperative RBC transfusion; Pu2009<u2009.001 for trend). In subgroup analyses, the association between any perioperative RBC transfusion and postoperative VTE remained statistically significant across all surgical subspecialties analyzed. The association between any perioperative RBC transfusion and the development of postoperative VTE also remained robust after 1:1 propensity score matching (47 142 matched pairs; matched OR,u20091.9; 95% CI, 1.8-2.1). Conclusions and Relevance The results of this study suggest that perioperative RBC transfusions may be significantly associated with the development of new or progressive postoperative VTE, independent of several putative confounders. These findings, if validated, should reinforce the importance of rigorous perioperative management of blood transfusion practices.

Hepatitis C care continuum and associated barriers among people who inject drugs in Chennai, India

BACKGROUNDnLittle is known regarding barriers to hepatitis C virus (HCV) treatment among people who inject drugs (PWID) in low-resource settings, particularly in the era of direct-acting antiviral therapies.nnnMETHODSnBetween March, 2015-August, 2016, a cross-sectional survey was administered to community-based PWID in Chennai, India to examine the HCV care continuum and associated barriers. Adjusted prevalence ratios (APR) were estimated by multivariable Poisson regression with robust variance.nnnRESULTSnAll participants were male (nu202f=u202f541); 152 participants had HCV mono-infection and 61 participants had HIV/HCV co-infection. Only one HCV mono-infected and one HIV/HCV co-infected participant was linked to HCV care. Overall, there was moderate knowledge of HCV disease but poor knowledge of HCV treatment. Higher total knowledge scores were negatively associated with HIV/HCV co-infection (vs. HCV mono-infection), though this was not statistically significant in adjusted analysis (APRu202f=u202f0.71 [95%CIu202f=u202f0.47-1.06]). Participants ≥45 years (APRu202f=u202f0.73 [95%CIu202f=u202f0.58-0.92]) and participants with HIV/HCV co-infection (APRu202f=u202f0.64 [95%CIu202f=u202f0.47-0.87]) were less willing to take weekly interferon injections for 12 weeks. Willingness to undergo HCV treatment improved with decreasing duration of therapy, higher perceived efficacy, and use of pills vs. interferon, though willingness to use interferon improved with decreasing duration of therapy. Most participants preferred daily visits to a clinic for HCV treatment versus receiving a months supply. Participants ≥45 years (vs. <45u202fyears; APRu202f=u202f0.70 [95%CIu202f=u202f0.56-0.88]) and participants with HIV/HCV co-infection (APRu202f=u202f0.75 [95%CIu202f=u202f0.57-0.98]) were less likely to intend on seeking HCV care. Common reasons for not having already seen a provider for HCV treatment differed by HIV status, and included low perceived need for treatment (HCV-mono-infected), competing money/health priorities and costs/fears about treatment (HIV/HCV-co-infected).nnnCONCLUSIONnResidual gaps in HCV knowledge and continuing negative perceptions related to interferon-based therapy highlight the need to scale-up educational initiatives. Readiness for HCV treatment was particularly low among HIV/HCV co-infected and older PWID, emphasizing the importance of tailored treatment strategies.

Penile Immune Activation and Risk of HIV Shedding: A Prospective Cohort Study

BackgroundnGenital immune activation is suspected to modulate local human immunodeficiency virus (HIV) RNA levels and the risk of sexual HIV transmission.nnnMethodsnA prospective, observational cohort study of 221 HIV-infected men undergoing male circumcision (MC) was conducted in Rakai, Uganda. Penile lavage samples collected from the coronal sulcus at baseline and 4 weekly visits after MC were assayed for pro-inflammatory cytokines and HIV RNA. The main analysis was limited to 175 men with detectable HIV plasma viral load (VL > 400 copies/mL; n = 808 visits). The primary exposures of interest were individual and total cytokine detection at the previous postoperative visit. Adjusted prevalence risk ratios (adjPRR) of detectable HIV shedding (VL > 40 copies/mL) were estimated by Poisson regression models with generalized estimating equations and robust variance estimators and included adjustment for plasma HIV VL.nnnFindingsnAmong men with a detectable plasma VL, penile HIV shedding was detected at 136 visits (16.8%). Detectable interleukin (IL)-1β (adjPRR = 2.14; 95% confidence interval (CI) = 1.02-4.48), IL-6 (adjPRR = 2.24; 95% CI = 1.28-3.90), IL-8 (adjPRR = 2.42; 95% CI = 1.15-5.08), IL-10 (adjPRR = 2.51; 95% CI = 1.67-3.80), and IL-13 (adjPRR = 1.87; 95% CI = 1.15-3.03) were associated with penile HIV shedding at the subsequent visit. Men with 2-4 (adjPRR = 2.36; 95% CI = 1.08-5.14) and 5-7 (adjPRR = 3.00; 95% CI = 1.28-7.01) detectable cytokines had a greater likelihood of detectable penile HIV shedding at the subsequent visit, compared to men with ≤ 1 detectable cytokine. The total number of detectable cytokines was also associated with a higher penile log10 HIV VL at the subsequent visit among HIV shedders.nnnInterpretationnPro-inflammatory cytokine production had a dose-dependent and temporal association with penile HIV shedding, suggesting that genital immune activation may increase the risk of sexual HIV transmission by driving local HIV replication.
