RESUMEN

BACKGROUND: Evidence on the distribution of pre-treatment HIV-1 drug resistance (HIVDR) among risk groups is limited in Africa. We assessed the prevalence, trends and transmission dynamics of pre-treatment HIVDR within and between MSM, people who inject drugs (PWID), female sex workers (FSWs), heterosexuals (HETs) and perinatally infected children in Kenya. METHODS: HIV-1 partial pol sequences from antiretroviral-naive individuals collected from multiple sources between 1986 and 2020 were used. Pre-treatment reverse transcriptase inhibitor (RTI), PI and integrase inhibitor (INSTI) mutations were assessed using the Stanford HIVDR database. Phylogenetic methods were used to determine and date transmission clusters. RESULTS: Of 3567 sequences analysed, 550 (15.4%, 95% CI: 14.2-16.6) had at least one pre-treatment HIVDR mutation, which was most prevalent amongst children (41.3%), followed by PWID (31.0%), MSM (19.9%), FSWs (15.1%) and HETs (13.9%). Overall, pre-treatment HIVDR increased consistently, from 6.9% (before 2005) to 24.2% (2016-20). Among HETs, pre-treatment HIVDR increased from 6.6% (before 2005) to 20.2% (2011-15), but dropped to 6.5% (2016-20). Additionally, 32 clusters with shared pre-treatment HIVDR mutations were identified. The majority of clusters had R0 ≥ 1.0, indicating ongoing transmissions. The largest was a K103N cluster involving 16 MSM sequences sampled between 2010 and 2017, with an estimated time to the most recent common ancestor (tMRCA) of 2005 [95% higher posterior density (HPD), 2000-08], indicating propagation over 12 years. CONCLUSIONS: Compared to HETs, children and key populations had higher levels of pre-treatment HIVDR. Introduction of INSTIs after 2017 may have abrogated the increase in pre-treatment RTI mutations, albeit in the HET population only. Taken together, our findings underscore the need for targeted efforts towards equitable access to ART for children and key populations in Kenya.

RESUMEN

BACKGROUND AND AIMS: The Liver Frailty Index (LFI) is a well-studied tool that evaluates frailty in patients with cirrhosis. Consisting of grip strength, chair stands, and balance testing, the LFI has been associated with increased mortality in patients awaiting liver transplant. We aimed to extend our understanding of frailty in cirrhosis by exploring the relationship between the LFI and the risk of (1) cirrhosis progression, (2) mortality, and (3) unplanned hospitalizations, in both compensated and decompensated disease. APPROACH AND RESULTS: Adult patients with cirrhosis from four centers in North America and one in India were included. Frailty was measured at baseline using the LFI and categorized as robust (LFI < 3.2), prefrail (LFI 3.2-4.5), and frail (LFI > 4.5). Progression of cirrhosis was defined by an increase in clinical stage, ranging from 1 to 5, from baseline using the D'Amico classification. Factors associated with progression, mortality, and hospitalizations were evaluated using multivariate regression models, with transplant as a competing risk. In total, 822 patients with cirrhosis were included. Average Model for End-Stage Liver Disease (MELD) score was 15.5 ± 6.0. In patients with compensated cirrhosis, being frail versus robust was associated with increased risk of progression to the next cirrhosis stage or to death (HR, 2.45; 95% CI, 1.14-5.29) and with an increased risk of unplanned hospitalizations (2.32; 95% CI, 1.13-4.79), after adjusting for age, sex, and MELD score. Similar HRs were observed in patients with decompensated cirrhosis. CONCLUSIONS: Frailty was an independent predictor of cirrhosis progression or death and unplanned hospitalization across patients with compensated and decompensated cirrhosis. Future studies are needed to evaluate the possibility of slowing cirrhosis disease progression by reversing or preventing frailty.

RESUMEN

HIV prevention method preferences were evaluated among Kenyan men who have sex with men (MSM) and transgender women (TW) from three sites: Kisumu, Nairobi and the Coast. Information sessions detailing the attributes, duration of protection, route of administration and probable visibility were attended by 464 HIV negative participants, of whom 423 (median age: 24 years) agreed to be interviewed. Across pairwise comparisons daily PrEP was by far the least preferred (1%); quarterly injections (26%) and monthly pills (23%) were most preferred, followed by yearly implant (19%) and condoms (12%). When participants were "forced" to choose their most preferred PrEP option, only 10 (2.4%) chose the daily pill; more (37.1%) chose the quarterly injection than the monthly pill (34.8%) and the yearly implant (25.8%). TW preferred the yearly implant over the quarterly injection. To achieve the rates of PrEP uptake and adherence necessary for protecting large proportions of vulnerable MSM and TW, a variety of long-acting products should be developed and made accessible to appeal to a diversity of preferences.

RESUMEN

Data on challenges with pre-exposure prophylaxis (PrEP) uptake and adherence among Kenyan gay, bisexual, and other men who have sex with men (GBMSM) are limited. In this mixed-methods sequential explanatory design study, our quantitative phase followed 157 at-risk, HIV-negative GBMSM who accepted PrEP and enrolled in a cohort with 12-month follow-up. Stored dried blood spots collected at two intervals were batch tested for tenofovir diphosphate (TFV-DP) concentrations at study end. Despite high self-reported adherence, only 14.6% of individuals had protective TFV-DP levels at any visit. Protective TFV-DP levels were positively associated with injection drug use and a self-assessed moderate risk of acquiring HIV, and negatively associated with time since enrolment. In our subsequent qualitative phase, an intensive workshop was conducted with the GBMSM community to identify barriers and facilitators to PrEP uptake and adherence. These data revealed numerous challenges with traditional PrEP programs that must be addressed through community collaborations.


RESUMEN: La evidencia respecto a desafíos existentes con aceptación y adherencia de la profilaxis previa a la exposición (PrEP) de VIH, entre los hombres homosexuales, bisexuales y otros hombres que tienen sexo con hombres (GBMSM) en Kenia es limitada. Condujimos un estudio de métodos mixtos y diseño explicativo secuencial. En la fase cuantitativa seguimos a 157 GBMSM VIH-negativos en riesgo que aceptaron PrEP y se inscribieron en una cohorte con un seguimiento de 12 meses. Analizamos, por lotes y al final del estudio, gotas de sangre seca recolectada a dos intervalos de tiempo y previamente almacenada, para determinar las concentraciones de difosfato de tenofovir (TFV-DP). A pesar de la alta adherencia autoinformada, solo el 14,6% de las personas tenían niveles protectores de TFV-DP en alguna visita. Los niveles protectores de TFV-DP se asociaron positivamente con el uso de drogas inyectables y un riesgo moderado autoevaluado de contraer el VIH, y negativamente con el tiempo transcurrido desde la inscripción. En la fase cualitativa posterior, conversamos con GBMSM de la comunidad para identificar las barreras y los facilitadores para la concientización, aceptación, adherencia y retención a PrEP. Estos datos revelaron numerosos desafíos con los programas tradicionales de PrEP que deben abordarse mediante colaboraciones comunitarias.

RESUMEN

BACKGROUND: Worldwide, sexual and gender minority individuals have disproportionate burden of HIV. There are limited quantitative data from sub-Saharan Africa on the intersection of risks experienced by transgender women (TGW) in comparison to cis-men who have sex with men (MSM). This analysis addresses this gap by comparing reported stigma, psychosocial measures of health, and sexual risk practices between TGW and cis-MSM in Kenya. METHODS: We analyzed data from the baseline visit of an ongoing prospective cohort study taking place in three diverse metropolitan areas. Eligible participants were HIV-negative, assigned male at birth, ages 18-29 years, and reported anal intercourse in the past 3 months with a man or TGW. Data collected by audio computer assisted self-interview included sociodemographic measures, and sexual practices occurring in the past 3 months. Multivariable regressions assessed differences between TGW and cis-MSM in selected sexual practices, depressive symptoms, alcohol and drug use, and stigma. RESULTS: From September, 2019, through May, 2021, 838 participants were enrolled: 108 (12.9%) TGW and 730 (87.1%) cis-MSM. Adjusting for sociodemographic variables, TGW were more likely than cis-MSM to report: receptive anal intercourse (RAI; adjusted prevalence ratio [aPR] = 1.59, 95% CI: 1.32 - 1.92), engaging in group sex (aPR = 1.15, 95% CI: 1.04 - 1.27), 4 or more male sex partners (aPR = 3.31, 95% CI: 2.52 - 4.35), and 3 or more paying male sex partners (aPR = 1.58, 95% CI: 1.04 - 2.39). TGW were also more likely to report moderate to severe depressive symptoms (aPR = 1.42, 95% CI: 1.01 - 1.55), and had similar alcohol and drug abuse scores as cis-MSM. In sensitivity analysis, similar to TGW, male-identifying individuals taking feminizing gender affirming therapy had an increased likelihood of reporting RAI and group sex, and greater numbers of male sex partners and paying male sex partners relative to cis-MSM. CONCLUSIONS: Across three metropolitan areas in Kenya, TGW were more likely to report depressive symptoms and increased sexual risk taking. We identified a need for research that better characterizes the range of gender identities. Our analysis affirms the need for programmatic gender-affirming interventions specific to transgender populations in Kenya and elsewhere in Africa.

RESUMEN

BACKGROUND: We determined how the vaginal and penile microbiomes contribute to herpes simplex virus type 2 (HSV-2) serostatus within sexual partnerships. METHODS: Microbiomes were characterized in cervicovaginal lavage and penile meatal swab specimens through high-throughput 16s ribosomal RNA gene amplicon sequencing. HSV-2 antibody was detected in serum specimens. We modeled vaginal and penile taxa and covariates contributing to HSV-2 status in women and men using bivariate probit analysis. RESULTS: Among 231 couples, HSV-2 was detected in both partners in 78 couples (33.8%), in the woman only in 52 (22.5%),in the man only in 27 (11.7%), and in neither in 74 (32.0%). Among the women (median age, 22 years) 10.9% had human immunodeficiency virus (HIV), and 21.4% had Bacterial vaginosis. Among men (median age, 26 years), 11.8% had HIV, and 55.0% circumcised. In an analysis with adjustment for sociodemographics and Bacterial vaginosis, enrichment of vaginal Gardnerella vaginalis and Lactobacillus iners was associated with increased likelihood of HSV-2 in both partners. Penile taxa (including Ureaplasma and Aerococcus) were associated with HSV-2 in women. CONCLUSIONS: We demonstrate that penile taxa are associated with HSV-2 in female partners, and vaginal taxa are associated with HSV-2 in male partners. Our findings suggest that couples-level joint consideration of genital microbiome and sexually transmitted infection or related outcomes could lead to new avenues for prevention.

RESUMEN

INTRODUCTION: The association between cirrhosis and driving performance is of particular clinical relevance because of the life-threatening safety issues both for the driver with cirrhosis and the general public. Study aims were to assess (i) driving competency through the use of an in-office computerized battery and on-road driving assessment (DriveABLE) and (ii) the association between minimal hepatic encephalopathy (MHE), in-office paper-pencil tools, and additional measures (e.g., frailty, depression, cognitive testing) with unsafe driving. METHODS: Patients were prospectively recruited from 2 tertiary care liver clinics. In-office tests and in-office and on-road assessments of driving competence were completed. The χ 2 test and 1-way analysis of variance were used to analyze differences among those with and without MHE. Logistic regression was used to evaluate predictors of an indeterminate/fail result on the in-office computerized driving assessment battery (DriveABLE Cognitive Assessment Tool [DCAT]). RESULTS: Eighty patients participated with a mean age of 57 years, 70% male, 75% Child-Pugh B/C, and 36% with a history of overt hepatic encephalopathy. Thirty percent met MHE criteria on both the psychometric hepatic encephalopathy score and the Stroop app tests. Only 2 patients (3%) were categorized as "unfit to drive" in the on-road driving test, one with MHE and the other without. Fifty-eight percent of the patients were scored as indeterminate/fail on the DCAT. This corresponded to a higher mean number of on-road driving errors (5.3 [SD 2.1] vs 4.2 [SD 1.6] in those who passed the DCAT, P = 0.01). Older age (odds ratio 1.3; confidence interval 1.1, 1.5; P = 0.001) and MHE by Stroop/psychometric hepatic encephalopathy score (odds ratio 11.0; confidence interval 2.3, 51.8; P = 0.002) were independently predictive of worse performance on the DCAT. DISCUSSION: Worse performance in in-office testing was associated with worse scores on a computerized driving assessment battery and more on-road driving errors, but in-office tools were insufficient to predict on-road driving failures. A diagnosis of MHE should not be used alone to restrict driving in patients with cirrhosis. At-risk patients require on-road driving tests under the supervision of driving regulatory agencies. Future studies should continue to refine and evaluate in-office or at-home testing to predict driving performance.

RESUMEN

BACKGROUND AND AIMS: The aim of this study was to evaluate the safety and effectiveness of Hemospray (Cook Medical, Winston-Salem, NC, USA), a hemostatic powder, as monotherapy for active peptic ulcer bleeding. METHODS: In this prospective, multicenter, single-arm study, patients with Forrest Ia or Ib peptic ulcers underwent endoscopic application of Hemospray as treatment of first intent. Effectiveness endpoints were successful hemostasis at the end of the index endoscopy, recurrent bleeding within 72 hours and from 72 hours to 30 days, adverse events requiring reintervention or resulting in morbidity or mortality, and 30-day mortality. RESULTS: Hemospray was successfully administered in 98.5% of patients (66/67). Hemostasis was achieved at the index endoscopy in 90.9% of patients (60/66) with Hemospray alone and in an additional 4 patients treated with additional modalities, yielding an overall hemostasis rate of 97.0% (64/66). Rebleeding occurred in 13.3% of patients (8/60), 5 within 72 hours and 3 between 72 hours and 30 days. Two cases of perforation and 2 patient deaths occurred during the study, but none of these cases or any other adverse events were attributed to the use of Hemospray. The rate of early rebleeding was significantly higher in patients with Forrest Ia ulcers compared with patients with Forrest Ib ulcers. Higher rates of early bleeding in patients with Forrest Ia ulcers is consistent with results from studies where Hemospray was used as rescue after failure of conventional methods. CONCLUSIONS: Hemospray is an effective initial treatment for patients with active peptic ulcer bleeding, but care should be taken to monitor for recurrent bleeding.

RESUMEN

We measured change in sexual practices and the incidence of C. trachomatis (CT) and N. gonorrhoeae (NG) within a prospective cohort of Kenyan MSM taking PrEP in Kenya. Over the one year of study participation, CT and NG were diagnosed in urine at baseline, 6- and 12- months. Multivariable Cox regression identified factors associated with incident infection. Sexual practices were assessed at baseline and every 3 months. We evaluated changes over time and in relation to PrEP adherence via generalized estimating equation analysis. From October 2017-January 2018, 158 participants initiated PrEP, having 10.3% baseline CT/NG prevalence (either or both). The incidence was 17.2 cases per 100 person-years (95% CI 11.7-25.5). Incident CT/NG increased with report of: transactional male sex partner (adjusted Hazard Ratio (aHR) = 2.46, p = 0.016, z = 2.40), regular female sex partner (aHR = 2.22, p = 0.051, z = 1.96), greater social support (highest vs. lowest quartile, aHR = 6.24, p = 0.012, z = 2.51), and CT/NG infection prior to enrollment (aHR = 2.90, p = 0.002, z = 3.03). Multiple sex partners, condomless sex, and transactional sex decreased over time and were not associated with PrEP adherence. Urethral CT/NG incidence remained high and there was no evidence of PrEP-related behavioral change. There is need for ongoing etiologic testing, improved understanding of risk from female sex partners, and development of more effective risk reduction interventions.

RESUMEN

BACKGROUND: Strategies to control coronavirus 2019 disease (COVID-19) have often been based on preliminary and limited data and have tended to be slow to evolve as new evidence emerges. Yet knowledge about COVID-19 has grown exponentially, and the expanding rollout of vaccines presents further opportunity to reassess the response to the pandemic more broadly. MAIN TEXT: We review the latest evidence concerning 10 key COVID-19 policy and strategic areas, specifically addressing: 1) the expansion of equitable vaccine distribution, 2) the need to ease restrictions as hospitalization and mortality rates eventually fall, 3) the advantages of emphasizing educational and harm reduction approaches over coercive and punitive measures, 4) the need to encourage outdoor activities, 5) the imperative to reopen schools, 6) the far-reaching and long-term economic and psychosocial consequences of sustained lockdowns, 7) the excessive focus on surface disinfection and other ineffective measures, 8) the importance of reassessing testing policies and practices, 9) the need for increasing access to outpatient therapies and prophylactics, and 10) the necessity to better prepare for future pandemics. CONCLUSIONS: While remarkably effective vaccines have engendered great hope, some widely held assumptions underlying current policy approaches call for an evidence-based reassessment. COVID-19 will require ongoing mitigation for the foreseeable future as it transforms from a pandemic into an endemic infection, but maintaining a constant state of emergency is not viable. A more realistic public health approach is to adjust current mitigation goals to be more data-driven and to minimize unintended harms associated with unfocused or ineffective control efforts. Based on the latest evidence, we therefore present recommendations for refining 10 key policy areas, and for applying lessons learned from COVID-19 to prevent and prepare for future pandemics.

RESUMEN

While it is clear that in many communities ideas about masculinity and circumcision are connected, it is still unclear how young Kenyan men in the former Nyanza province from the traditionally non-circumcising Luo people perceive voluntary medical male circumcision as connected to masculinity and the role of voluntary medical male circumcision in the transition from boyhood to manhood. The objective of this study was to explore norms of masculinity and the decision-making process among Luo young men to provide a better understanding of how circumcision and masculinity relate to cultural norms within this community. The methodology consisted of eight FGDs with male peer groups and 24 in-depth interviews to elicit young men's perceptions of masculinity and voluntary medical male circumcision. Findings from thematic analysis reveal that young men described several key characteristics of masculinity including responsibility, bravery and sexual attractiveness. For some young men, voluntary medical male circumcision has embedded itself into cultural norms of masculinity by being a step in the transition from boyhood to manhood and by being a marker of some of these masculine characteristics. In the case of voluntary medical male circumcision, there may be opportunities to integrate other programming that helps men transition into healthy adulthood.

RESUMEN

There is a rapidly evolving need for e-health to support chronic disease self-management and connect patients with their healthcare teams. Patients with cirrhosis have a high symptom burden, significant comorbidities, and a range of psychological and cognitive issues. Patients with cirrhosis were assessed for their readiness and interest in e-health. Adults attending one of two outpatient cirrhosis clinics in Alberta were recruited. Eligible participants were not required to own or have experience with digital technologies or the Internet. Medical history, socioeconomic status, and attitudes regarding e-health, the Computer Proficiency Questionnaire, and the Mobile Device Proficiency Questionnaire were used to describe participants' knowledge and skills. Of the 117 recruited patients, 68.4% owned a computer and 84.6% owned a mobile device. Patients had mean proficiency scores of 72.8% (SD 25.9%) and 69.3% (SD 26.4%) for these devices, respectively. In multiple regression analyses, significant predictors of device proficiency were age, education, and household income. Most patients (78.7%) were confident they could participate in videoconferencing after training and most (61.5%) were interested in an online personalized health management program. This diverse group of patients with cirrhosis had technology ownership, proficiency, and online behaviours similar to the general population. Moreover, the patients were very receptive to e-health if training was provided. This promising data is timely given the unique demands of COVID-19 and its influence on self-management and healthcare delivery to a vulnerable population.

RESUMEN

OBJECTIVES: Patients with cirrhosis experience a worsened quality of life; this may be quantified by the use of health-related QoL (HRQoL) constructs, such as the chronic liver disease questionnaire (CLDQ) and EuroQoL Group-visual analog scale (EQ-VAS). In this multicenter prospective study, we aimed to evaluate HRQoL as a predictor of unplanned hospital admission/early mortality, identify HRQoL domains most affected in cirrhosis, and identify predictors of low HRQoL in patients with cirrhosis. METHODS: Multivariable logistic regression was used to determine independent association of HRQoL with primary outcome and identify predictors of low HRQoL. HRQoL was also compared with population norms. RESULTS: In this cohort of 402 patients with cirrhosis, mean model for end-stage liver disease was 12.5 (4.9). More than 50% of the cohort had low HRQoL, considerably lower than population norms. HRQoL (measured by either CLDQ or EQ-VAS) was independently associated with the primary outcome of short-term unplanned hospitalization/mortality. Every 1-point increase in the CLDQ and every 10-point increase in the EQ-VAS reduced the risk of reaching this outcome by 30% and 13%, respectively. Patients with cirrhosis had lower HRQoL scores than population norms across all domains of the CLDQ. Younger age, female sex, current smoker, lower serum albumin, frailty, and ascites were independently associated with low CLDQ. DISCUSSION: Patients with cirrhosis experience poor HRQoL. HRQoL is independently associated with increased mortality/unplanned hospitalizations in patients with cirrhosis and could be an easy-to-use prognostic screen that patients could complete in the waiting room before their appointment.

RESUMEN

OBJECTIVE: STIs disproportionately affect men who have sex with men (MSM) in sub-Saharan Africa. We identified factors associated with incident Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among MSM in the Anza Mapema cohort study in Kisumu, Kenya. METHODS: We enrolled 711 MSM who underwent HIV testing and counselling, medical history and examination, and collection of demographic and behavioural information. They also provided urine and rectal swab specimens for CT and NG testing by qualitative PCR at baseline and at months 6 and 12. Separate multivariable Cox regression models identified factors associated with first incident urethral or rectal infection. RESULTS: Among the 619 men aged 18-54 years included in this analysis, there were 83 first incident urethral CT/NG infections (14.4 cases per 100 person-years (PY)) and 40 first incident rectal infections (6.84 cases per 100 PY), and an overall incidence of 18.0 cases per 100 PY (95% CI 14.8 to 21.8). Most urethral (84%) and rectal (81%) infections were asymptomatic. In the adjusted model, the risk of first incident urethral CT/NG decreased by 4% for each 1-year increase in age and was 41% lower for men who reported their partner used condom at last sexual encounter. Men who were HIV-positive had a 68% less risk of urogenital CT/NG compared with those who were negative. Men who reported being usually receptive or versatile as compared with usually insertive had an 81% increased risk of incident urogenital CT/NG. CONCLUSION: Our study demonstrated a high incidence of urethral CT/NG infection, with somewhat lower incidence of rectal CT/NG infection, despite repeated testing and treatment, highlighting the need for preventive interventions to decrease the burden of CT/NG among Kenyan MSM. Most infections were asymptomatic, and routine aetiological screening for STIs is recommended.

RESUMEN

BACKGROUND: Up to 50% of women with nonoptimal vaginal microbial community state type (CST) have bacterial vaginosis (BV). Little is known about what distinguishes women with and without BV diagnosis within nonoptimal CST. We identified features of women and their male sex partners associated with BV among women with nonoptimal vaginal CST. METHODS: In this prospective study, 252 heterosexual couples were observed at 1, 6, and 12 months after baseline. Microbiomes were characterized in cervicovaginal lavage and penile meatal swabs through high-throughput 16s ribosomal RNA gene amplicon sequencing. Nonoptimal CST was defined as CST-IV. Bacterial vaginosis was defined as a Nugent score of 7 to 10. Generalized estimating equation analysis estimated adjusted odds ratios (aORs) for BV among women with nonoptimal CST. RESULTS: At baseline, women with nonoptimal CST were a median age of 22 years, 44% had BV, 16% had HIV, and 66% had herpes simplex virus (HSV) type 2. Male partners were a median age of 27 years, 12% had HIV, 48% had HSV-2, and 55% were circumcised. Within nonoptimal CST, Sneathia sanguinegens, Prevotella species, Prevotella amnii, and Clostridiales, BV-associated bacteria-2 were statistically significantly enriched in observations with BV. In multivariable generalized estimating equation controlling for CST, HIV, and HSV-2, BV was increased among women with CST-IVA (aOR, 1.91; P = 0.087), HIV (aOR, 2.30; P = 0.051), HSV-2 (aOR, 1.75; P = 0.065), and enrichment of male partner penile taxa: Dialister (aOR, 1.16; P = 0.034), Megasphaera (aOR, 1.22; P = 0.001), and Brevibacterium (aOR, 1.13; P = 0.019).These results provide insights into factors differentiating women with BV among those with nonoptimal vaginal CST. Interrupting the sexual exchange of penile and vaginal taxa may be beneficial for preventing pathologic state of vaginal microbiome.

RESUMEN

OBJECTIVES: In settings where laboratory capacity is limited, the WHO recommends presumptive treatment for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) in asymptomatic men who have sex with men (MSM) at high risk for these infections. However, little is known about how best to target this intervention. We aimed to identify correlates of anorectal NG/CT infection in Kenyan MSM with and without anorectal symptoms and evaluate the performance of an empirical, model-based risk score to identify cases in asymptomatic men. METHODS: Anorectal NG/CT infections were diagnosed by the Abbott RealTime NG/CT nucleic acid amplification testamong 698 MSM at enrolment into the Anza Mapema study. Multivariable logistic regression was used to identify correlates of anorectal NG/CT infection in men with and without anorectal symptoms. Using coefficients from the final multivariable model for asymptomatic men, we calculated a risk score for each participant. Risk score performance was determined by calculating the sensitivity, specificity and number needed to treat (NNT) to identify one NG/CT infection. RESULTS: Overall anorectal NG/CT infection prevalence was 5.2% (n=36), of which 58.3% (n=21) were asymptomatic. Factors associated with anorectal NG/CT infection in asymptomatic men were aged 18-24 years (aOR=7.6; 95% CI: 1.7 to 33.2), HIV positive serostatus (aOR=6.9; 95% CI: 2.2 to 21.6) and unprotected anal sex in the past 3 months (aOR=3.8; 95% CI: 1.2 to 11.9). Sensitivity and specificity were optimal (81.0% and 66.1%, respectively) at a model-derived risk score cut-point ≥3, and the NNT was 12. CONCLUSIONS: A model-derived risk score based on correlates of anorectal NG/CT infection in asymptomatic participants would be sensitive and efficient (i.e, low NNT) for targeting presumptive treatment. If validated in other settings, this risk score could improve on the WHO algorithm and help reduce the burden of asymptomatic anorectal NG/CT infections among MSM in settings where diagnostic testing is not available.

RESUMEN

BACKGROUND AND AIMS: Acute lower GI bleeding is a frequent cause of hospital admission. The objective of this study was to evaluate the safety and performance of a hemostatic powder (TC-325/Hemospray) in the treatment of nonvariceal lower GI bleeding. METHODS: Patients were enrolled into this prospective, multicenter, single-arm study at 4 tertiary care centers in Canada. Fifty patients with active lower GI bleeding of multiple different causes (52 bleeding sites) underwent topical endoscopic application of hemostatic powder. The primary endpoint was powder-related adverse events within 30 days of the index procedure. Secondary endpoints were initial hemostasis as well as recurrent bleeding and mortality within 30 days of the index procedure. RESULTS: Most patients (96%) had a single bleeding site, and most bleeding (73%) was due to polypectomy. Overall, the powder was applied as monotherapy in 13 bleeding sites (25%), as combination therapy in 22 bleeding sites (42.3%), and as rescue therapy in 17 bleeding sites (32.7%). Hemostasis was achieved in 98% of patients. No patient experienced a powder-related adverse event. Five patients (10%) developed recurrent bleeding within 30 days. One patient (2%) died within 30 days of powder application, but the death was not directly related to hemostatic powder use. CONCLUSIONS: The hemostatic powder is a safe and effective option for patients with lower GI bleeding of varying causes, and in particular, postpolypectomy hemorrhage. The hemostatic powder is effective as monotherapy, part of a combination approach, or as a rescue therapeutic option for the treatment of nonvariceal lower GI bleeding.

RESUMEN

We examined virological non-suppression (VLN) among youth ages 13-24 years receiving HIV treatment in public health facilities in six southern Malawi districts. We also tested three ART adherence measures to determine how well each identified VLN: pill counts, a Likert scale item, and a visual analogue scale. VLN was defined as HIV RNA > 1000 copies/ml. Of the 209 youth, 81 (39%) were virally non-suppressed. Male gender and stigma were independently associated with VLN; social support and self-efficacy were independently protective. Pill count had the highest positive predictive value (66.3%). Using a pill count cut-off of < 80% nonadherence, 36 (17%) of the youth were non-adherent. Of the adherent, 120 (69%) were viral suppressed. Results indicate the need to address HIV-related stigma and to bolster social support and selfefficacy in order to enhance viral suppression. In the absence of viral load testing, pill count appears the most accurate means to assess VLN.

RESUMEN

OBJECTIVES: This paper aimed to synthesize empirical findings of patient extratherapeutic interpersonal variables associated with individual psychotherapy treatment outcomes in adult outpatients with depression. METHODS: A systematic search strategy was used to identify relevant studies. Thematic analysis was used to identify recurring themes in the findings. RESULTS: Forty studies met search criteria. Three themes of patient extratherapeutic interpersonal variables were identified: capacity to engage with others, capacity to navigate relationships, and capacity to achieve intimacy, progressing from basic to advanced levels of interpersonal interaction. Interpersonal variables such as interpersonal distress and style, attachment orientation, and quality of object relations were particularly useful in predicting treatment outcomes, whereas access to social support and marital status provided mixed results, likely because they do not account for relationship quality. CONCLUSIONS: Recognizing variables associated with treatment response can help clinicians identify patients at risk for nonresponse and guide efforts for adapting existing therapies and developing new ones.

RESUMEN

Global experts recognize the need to transform conventional models of healthcare to create adolescent responsive health systems. As countries near 80% coverage of voluntary medical male circumcision (VMMC) for those aged 15-49 years, prioritization of younger men becomes critical to VMMC sustainability. This special supplement reporting 9 studies focusing on adolescent VMMC programming and services comes at a critical time. Eight articles report how well adolescents are reached with the World Health Organization's minimum package for comprehensive human immunodeficiency virus (HIV) prevention in South Africa, Zimbabwe, and Tanzania, analyzing motivation, counseling, wound healing, parental involvement, female peer support, quality of in-service communication, and providers' perceptions, and one presents models for achieving high VMMC coverage by 2021. One important finding is that adolescent boys, especially the youngest, experience gaps in their comprehension of key elements in the World Health Organization's minimum package. Although parents, counselors, and providers are involved and supportive, they are inadequately prepared to counsel youth, partly owing to discomfort with adolescent sexuality. At the country level, deliberately prioritizing young adolescents (aged 10-14 years) is likely to achieve national coverage targets more quickly and cost-effectively than continuing to focus on older, harder-to-reach men. The studies in this supplement point to areas where VMMC programs are achieving successes and they reveal areas for improvement. Given that prioritizing adolescents will be the best means of achieving sustainable VMMC for HIV prevention for the foreseeable future, applying the lessons learned here will increase the effectiveness of VMMC programs.
