RESUMEN
Community-based delivery of oral HIV self-testing (HIVST) may expand access to testing among adolescents and young adults (AYA). Eliciting youth perspectives can help to optimize these services. We conducted nine focus group discussions (FGDs) with HIV negative AYA aged 15-24 who had completed oral HIVST following community-based distribution through homes, pharmacies, and bars. FGDs were stratified by distribution point and age (15-17, 18-24). Participants valued HIVST because it promoted greater autonomy and convenience compared to traditional clinic-based testing. AYA noted how HIVST could encourage positive behavior change, including using condoms to remain HIV negative. Participants recommended that future testing strategies include individualized, ongoing support during and after testing. Support examples included access to trained peer educators, multiple community-based distribution points, and post-test support via phones and websites. Multiple distribution points and trained peer educators' involvement in all steps of distribution, testing, and follow-up can enhance future community-based HIVST programs.

Oral HIV self-testing (HIVST) may expand access to testing among hard-to-reach reach adolescents and young adults (AYA). We evaluated community-based HIVST services for AYA in an urban settlement in Kenya. Peer-mobilizers recruited AYA ages 15-24 through homes, bars/clubs, and pharmacies. Participants were offered oral HIVST, optional assistance and post-test counseling. Outcomes were HIVST acceptance and completion (self-report and returned kits). Surveys were given at enrollment, post-testing, and 4 months. Log-binomial regression evaluated HIVST preferences by venue. Among 315 reached, 87% enrolled. HIVST acceptance was higher in bars/clubs (94%) than homes (86%) or pharmacies (75%). HIVST completion was 97%, with one confirmed positive result. Participants wanted future HIVST at multiple locations, include PrEP, and cost ≤ $5USD. Participants from bars/clubs and pharmacies were more likely to prefer unassisted testing and peer-distributers compared to participants from homes. This differentiated community-based HIVST strategy could facilitate engagement in HIV testing and prevention among AYA.

School-related factors may influence retention in care and adherence to antiretroviral therapy (ART) among adolescents with human immunodeficiency virus (HIV). We analyzed data from in-depth interviews with 40 adolescents with HIV (aged 14 -19 years), 40 caregivers of adolescents with HIV, and 4 focus group discussions with healthcare workers to evaluate contextual factors affecting adherence to ART and clinic attendance among adolescents, with a focus on the school environment. Informed by Anderson's Model of Health Services Utilization, transcripts were systematically coded and synthesized to identify school-related themes. All groups identified the school environment as a critical barrier to engagement in HIV care and medication adherence for adolescents with HIV. Adolescent participants reported inflexible school schedules and disclosure to school staff as the biggest challenges adhering to clinic appointments and ART. Adolescents described experiencing stigma and discrimination by peers and school staff and would adjust when, where and how often they took ART to avoid inadvertent disclosure. Boarding school students faced challenges because they had limited private space or time. Caregivers were often instrumental in navigating school permissions, including identifying a treatment supporter among school staff. Additional research engaging school staff may guide interventions for schools to reduce stigma and improve adherence and retention.

This prospective study of HIV-positive Kenyan women in serodiscordant couples examined relationships between psychosocial factors, viral suppression, and condomless sex. Participants were screened for alcohol use disorders and intimate partner violence (IPV) annually and depressive symptoms every 6 months. Prostate specific antigen (PSA) detection was used as a marker for condomless sex. A total of 151 participants contributed 349 person-years of follow-up. Hazardous/harmful alcohol use was associated with increased risk of detecting PSA in vaginal secretions (aRR 1.99, 95%CI 1.08-3.66, χ2 = 4.85 (1)), while IPV and depression were not. Events representing HIV transmission potential, where there was biological evidence of condomless sex at a visit with a detectable plasma viral load, were observed at 2% of visits. The high prevalence of IPV and association between alcohol use and sexual risk suggest the need for monitoring and support for these conditions as part of comprehensive HIV care for women.

Motile cilia and flagella are whiplike cellular organelles that bend actively to propel cells or move fluid in passages such as airways, brain ventricles, and the oviduct. Efficient motile function of cilia and flagella depends on coordinated interactions between active forces from an array of motor proteins and passive mechanical resistance from the complex cytoskeletal structure (the axoneme). However, details of this coordination, including axonemal mechanics, remain unclear. We investigated two major mechanical parameters, flexural rigidity and interdoublet shear stiffness, of the flagellar axoneme in the unicellular alga Chlamydomonas reinhardtii. Combining experiment, theory, and finite element models, we demonstrate that the apparent flexural rigidity of the axoneme depends on both the intrinsic flexural rigidity (EI) and the elastic resistance to interdoublet sliding (shear stiffness, ks). We estimated the average intrinsic flexural rigidity and interdoublet shear stiffness of wild-type Chlamydomonas flagella in vivo, rendered immotile by vanadate, to be EI = 840 ± 280 pNâ µm(2) and ks = 79.6 ± 10.5 pN/rad, respectively. The corresponding values for the pf3; cnk11-6 double mutant, which lacks the nexin-dynein regulatory complex (N-DRC), were EI = 1011 ± 183 pN·µm(2) and ks = 39.3 ± 6.0 pN/rad under the same conditions. Finally, in the pf13A mutant, which lacks outer dynein arms and inner dynein arm c, the estimates were EI = 777 ± 184 pN·µm(2) and ks = 43.3 ± 7.7 pN/rad. In the two mutant strains, the flexural rigidity is not significantly different from wild-type (p > 0.05), but the lack of N-DRC (in pf3; cnk11-6) or dynein arms (in pf13A) significantly reduces interdoublet shear stiffness. These differences may represent the contributions of the N-DRCs (â¼40 pN/rad) and residual dynein interactions (â¼35 pN/rad) to interdoublet sliding resistance in these immobilized Chlamydomonas flagella.

BACKGROUND: Studies of alcohol use and sexual behavior in African populations have primarily been cross-sectional, used nonvalidated measures of alcohol use, or relied on self-reported sexual risk endpoints. Few have focused on human immunodeficiency virus (HIV)-positive women. METHODS: Longitudinal data were collected from a cohort of HIV-positive Kenyan female sex workers. At enrollment and annual visits, participants were asked about past-year alcohol use using the Alcohol Use Disorders Identification Test (AUDIT). The primary endpoint was detection of prostate-specific antigen (PSA) in vaginal secretions at quarterly examinations. Associations between hazardous/harmful alcohol use (AUDIT score ≥7), PSA detection, and secondary measures of sexual risk were evaluated using generalized estimating equations with a log binomial regression model. RESULTS: A total of 405 women contributed 2750 vaginal samples over 606 person-years of follow-up. Hazardous/harmful alcohol use was reported at 16.6% of AUDIT assessments and was associated with higher risk of PSA detection (relative risk 1.50; 95% confidence interval, 1.11-2.01) relative to no alcohol use. This association was attenuated and no longer statistically significant, after adjusting for age, work venue, intimate partner violence, depression, and partnership status (adjusted relative risk, 1.13; 95% confidence interval, 0.82-1.56). In exploratory analyses, alcohol use was associated with self-report of unprotected sex and with sexually transmitted infection acquisition. CONCLUSIONS: Although hazardous/harmful alcohol use was not associated with detection of PSA in adjusted analysis, associations with secondary outcomes suggest that alcohol use is at least a marker of sexual risk behavior.

We conducted a prospective cohort study to test the hypothesis that intimate partner violence (IPV) is associated with unprotected sex in HIV-positive female sex workers in Mombasa, Kenya. Women completed monthly visits and quarterly examinations. Any IPV in the past year was defined as ≥1 act of physical, sexual, or emotional violence by the current or most recent emotional partner ('index partner'). Unprotected sex with any partner was measured by self-report and prostate specific antigen (PSA) test. Recent IPV was associated with significantly higher risk of unprotected sex (adjusted relative risk [aRR] 1.91, 95 % CI 1.32, 2.78, p = 0.001) and PSA (aRR 1.54, 95 % CI 1.17, 2.04, p = 0.002) after adjusting for age, alcohol use, and sexual violence by someone besides the index partner. Addressing IPV in comprehensive HIV programs for HIV-positive women in this key population is important to improve wellbeing and reduce risk of sexual transmission of HIV.

We conducted a prospective cohort study to evaluate intimate partner violence (IPV) as a risk factor for detectable plasma viral load in HIV-positive female sex workers (FSWs) on antiretroviral therapy (ART) in Kenya. IPV in the past year was defined as ≥1 act of physical, sexual, or emotional violence by the index partner (i.e. boyfriend/husband). The primary outcome was detectable viral load (≥180 copies/ml). In-depth interviews and focus groups were included to contextualize results. Analyses included 195 women (570 visits). Unexpectedly, IPV was associated with significantly lower risk of detectable viral load (adjusted relative risk 0.21, 95 % CI 0.05-0.84, p-value = 0.02). Qualitative findings revealed that women valued emotional and financial support from index partners, despite IPV. IPV was not a major barrier to ART adherence. The observed association between IPV and lower risk of detectable viral load in FSWs may be due to unmeasured personal and relationship factors, warranting further research.

The south of Mexico has traditionally faced disproportionate social, health and economic disadvantage relative to the rest of the country, due in part to lower levels of economic and human development, and barriers faced by Indigenous populations. The state of Oaxaca, in particular, has one of the highest proportions of Indigenous people and consistently displays high rates of maternal mortality, sexually transmitted infections and teenage pregnancy. This study examines how social values and norms surrounding sexuality have changed between two generations of women living in Indigenous communities in Oaxaca. We conducted semi-structured in-depth interviews with 19 women from two generational cohorts in 12 communities. Comparison views of these two cohorts suggest that cultural gender norms continue to govern how women express and experience their sexuality. In particular, feelings of shame and fear permeate the expression of sexuality, virginity continues be a determinant of a woman's worth and motherhood remains the key attribute to womanhood. Evidence points to a transformation of norms, and access to information and services related to sexual health is increasing. Nonetheless, there is still a need for culturally appropriate sex education programmes focused on female empowerment, increased access to sexual health services, and a reduction in the stigma surrounding women's expressions of sexuality.

Motile cilia are essential components of the mucociliary escalator and are central to respiratory-tract host defenses. Abnormalities in these evolutionarily conserved organelles cause primary ciliary dyskinesia (PCD). Despite recent strides characterizing the ciliome and sensory ciliopathies through exploration of the phenotype-genotype associations in model organisms, the genetic bases of most cases of PCD remain elusive. We identified nine related subjects with PCD from geographically dispersed Amish communities and performed exome sequencing of two affected individuals and their unaffected parents. A single autosomal-recessive nonsynonymous missense mutation was identified in HEATR2, an uncharacterized gene that belongs to a family not previously associated with ciliary assembly or function. Airway epithelial cells isolated from PCD-affected individuals had markedly reduced HEATR2 levels, absent dynein arms, and loss of ciliary beating. MicroRNA-mediated silencing of the orthologous gene in Chlamydomonas reinhardtii resulted in absent outer dynein arms, reduced flagellar beat frequency, and decreased cell velocity. These findings were recapitulated by small hairpin RNA-mediated knockdown of HEATR2 in airway epithelial cells from unaffected donors. Moreover, immunohistochemistry studies in human airway epithelial cells showed that HEATR2 was localized to the cytoplasm and not in cilia, which suggests a role in either dynein arm transport or assembly. The identification of HEATR2 contributes to the growing number of genes associated with PCD identified in both individuals and model organisms and shows that exome sequencing in family studies facilitates the discovery of novel disease-causing gene mutations.

The motion of flagella and cilia arises from the coordinated activity of dynein motor protein molecules arrayed along microtubule doublets that span the length of axoneme (the flagellar cytoskeleton). Dynein activity causes relative sliding between the doublets, which generates propulsive bending of the flagellum. The mechanism of dynein coordination remains incompletely understood, although it has been the focus of many studies, both theoretical and experimental. In one leading hypothesis, known as the geometric clutch (GC) model, local dynein activity is thought to be controlled by interdoublet separation. The GC model has been implemented as a numerical simulation in which the behavior of a discrete set of rigid links in viscous fluid, driven by active elements, was approximated using a simplified time-marching scheme. A continuum mechanical model and associated partial differential equations of the GC model have remained lacking. Such equations would provide insight into the underlying biophysics, enable mathematical analysis of the behavior, and facilitate rigorous comparison to other models. In this article, the equations of motion for the flagellum and its doublets are derived from mechanical equilibrium principles and simple constitutive models. These equations are analyzed to reveal mechanisms of wave propagation and instability in the GC model. With parameter values in the range expected for Chlamydomonas flagella, solutions to the fully nonlinear equations closely resemble observed waveforms. These results support the ability of the GC hypothesis to explain dynein coordination in flagella and provide a mathematical foundation for comparison to other leading models.

Few prospective studies have evaluated the association between alcohol use and STI acquisition among African women. We examined the association between baseline drinking frequency and STIs in a cohort of Kenyan women reporting transactional sex. The association between alcohol use and STI differed significantly by HIV status. Among 139 HIV-positive women, STI acquisition was significantly associated with consuming 1-7 drinks/week and marginally associated with ≥8 drinks/week in unadjusted analyses. However, no association between alcohol use and STIs was observed among 335 HIV-negative women. Addressing alcohol use within comprehensive HIV care may also reduce the burden of STIs among high-risk women.

INTRODUCTION: Efforts to improve health outcomes among adolescents and young adults living with HIV (ALHs) are hampered by limited adolescent engagement in HIV-related research. We sought to understand the views of adolescents, caregivers and healthcare workers (HCWs) about who should make decisions regarding ALHs' research participation. METHODS: We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) with ALHs (aged 14-24 years), caregivers of ALHs and HCWs from six HIV care clinics in Western Kenya. We used semi-structured guides to explore ALHs' involvement in research decisions. Transcripts were analysed using thematic analysis; perspectives were triangulated between groups. RESULTS: We conducted 24 FGDs and 44 IDIs: 12 FGDs with ALHs, 12 with caregivers, and 44 IDIs with HCWs, involving 216 participants. HCWs often suggested that HIV research decision-making should involve caregivers and ALHs deciding together. In contrast, ALHs and parents generally thought decisions should be made individually, whether by HCWs/research teams (although this is likely ethically problematic), adolescents or caregivers. Caregiver and ALH preferences depended on ALHs' age, with younger ALHs requiring more support. A few caregivers felt that ALHs should consult with the research team/HCWs due to their greater knowledge of clinical care. ALHs emphasised that they should independently decide because they thought they had the right to do so and the capacity to consent. Poor communication and parental non-disclosure of HIV status influenced ALHs' views to exclude caregivers from decision-making. Regarding influences on research decision-making, ALHs were more willing to participate based on perceived contribution to science and less interested in participating in studies with potential risks, including loss of confidentiality. DISCUSSION: While research teams and HCWs felt that adolescents and caregivers should jointly make research decisions, ALHs and caregivers generally felt individuals should make decisions. As ALHs sometimes find caregiver support lacking, improving family dynamics might enhance research engagement.

Youth living with HIV (YLHIV) report that negative interactions with health care workers (HCWs) affects willingness to return to care. This stepped wedge randomized trial evaluated effectiveness of a standardized patient actor (SP) HCW training intervention on adolescent engagement in care in Kenya. HCWs caring for YLHIV at 24 clinics received training on adolescent care, values clarification, communication, and motivational interviewing, with 7 SP encounters followed by facilitated feedback of videotaped interactions. Facilities were randomized to timing of the intervention. The primary outcome was defined as return within 3 months after first visit (engagement) among YLHIV who were either newly enrolled or who returned to care after >3 months out of care. Visit data was abstracted from electronic medical records. Generalized linear mixed models adjusted for time, being newly enrolled, and clustering by facility. YLHIV were surveyed regarding satisfaction with care. Overall, 139 HCWs were trained, and medical records were abstracted for 4,595 YLHIV. Median YLHIV age was 21 (IQR 19-23); 82% were female, 77% were newly enrolled in care, and 75% returned within 3 months. Half (54%) of trained HCWs remained at their clinics 9 months post-training. YLHIV engagement improved over time (global Wald test, p = 0.10). In adjusted models, the intervention showed no significant effect on engagement [adjusted Prevalence Ratio (aPR) = 0.95, 95% Confidence Interval (CI): 0.88-1.02]. Newly enrolled YLHIV had significantly higher engagement than those with prior lapses in care (aPR = 1.18, 95%CI: 1.05-1.33). Continuous satisfaction with care scores were significantly higher by wave 3 compared to baseline (coefficient = 0.38, 95%CI: 0.19-0.58). Despite provider skill improvement, there was no effect of SP training on YLHIV engagement in care. This may be due to temporal improvements or turnover of trained HCWs. Strategies to retain SP-training benefits need to address HCW turnover. YLHIV with prior gaps in care may need more intensive support.

RESUMEN
Lawyers are important actors shaping the abortion debate in Mexico. Of 250 private and public sector criminal lawyers surveyed from four regions, the majority knew about abortion laws in their states. At least 80% agreed with abortion in cases of rape, risk to a woman's life or health, and fetal malformations. Overall, 61% agreed with the Mexico City law and 84% would defend a woman denied a legal abortion. In multivariate analysis, being very knowledgeable of abortion laws was a significant predictor of more "progressive" abortion opinions, support for the Mexico City law, and support for the health indication.

BACKGROUND: Health care worker (HCW) training using standardized patient actors (SPs) is an evidence-based approach for improving patient-provider interactions. We evaluated whether SP training among HCWs in Western Kenya improved the quality of pre-exposure prophylaxis (PrEP) counseling for adolescent girls and young women (AGYW). METHODS: We conducted a 2-day SP training intervention among HCWs providing PrEP counseling for AGYW. Six trained SPs role played one encounter each with HCWs following scripts depicting common PrEP-seeking scenarios. SPs used checklists to report and discuss domains of adherence to national PrEP guidelines, communication, and interpersonal skills using validated scales after each encounter. HCWs presented to each case in a random order. Overall and domain-specific mean score percentages were compared between the first and subsequent case encounters using generalized linear models, clustering by HCWs. RESULTS: During 564 training cases among 94 HCWs, the overall mean quality of PrEP counseling score was 83.1 (SD: 10.1); scores improved over the course of the 6 encounters (P < 0.001). Compared with the first case encounter, the mean scores for the fourth were significantly higher (79.1 vs. 85.9, P < 0.001). The mean scores plateaued from the fourth to the sixth case (85.2). Although HCWs demonstrated high baseline communication (95.3) and interpersonal skills (83.7), adherence to PrEP guidelines at baseline was suboptimal (57.6). By the fourth case, scores increased significantly (P < 0.001) for all domains. CONCLUSIONS: SP training improved PrEP counseling overall and in domains of interpersonal skills, use of guidelines, and communication with AGYW and could be useful in efforts to improve the quality of PrEP counseling for AGYW.

BACKGROUND: Poor health care worker (HCW) interactions with adolescents negatively influence engagement in HIV care. We assessed the impact of standardized patient actor training on HCW competence in providing adolescent HIV care in Kenya. METHODS: We conducted pre-post cross-sectional surveys and qualitative exit interviews during a stepped wedge randomized trial. Cross-sectional surveys assessed self-rated competence in providing adolescent services before and after the intervention, and training satisfaction. In-depth interviews with a subset of HCW participants one year after training. RESULTS: Over 90% of HCWs reported satisfaction with the training and there was significant improvement in self-rated competence scores (mean = 4.63 [highest possible score of 5] post-training vs 3.86 pre-training, p < 0.001). One-year following training, HCWs reported using skills in patient-centered communication and structuring an adolescent clinical encounter. CONCLUSIONS: This SP training intervention improved self-rated competence and showed sustained perceived impact on HCW skills in adolescent HIV service provision one year later.

BACKGROUND: Mexico has experienced a disproportionate mortality burden due to the influenza A(HIN1) pandemic. A study was undertaken to investigate the sociodemographic and clinical characteristics of the first 100 patients who died from confirmed influenza A(H1N1). METHODS: A clinical evaluation was made of the first 100 consecutive deaths of confirmed cases between 10 April and 28 May 2009 reported by the Federal Ministry of Health. Statistical analysis included disease frequencies and descriptive comparisons with national health data. RESULTS: Most patients (60%) were aged 30-79 years, 53% were female and 40% were residents of Mexico City. On admission, 50% had one or more chronic medical conditions including metabolic syndrome (40%), cardiovascular disease (21%), diabetes (20%), hypertension (20%) and respiratory disease (8%). 38% of women and 26% of men were obese based on body mass index). The main clinical symptoms were fever (84%), cough (85%), dyspnoea (75%) and myalgia (30%). The frequency of all chronic diseases was higher in this sample than in the national statistics. Most (82%) developed symptoms before the Mexican government issued the influenza alert (24 April). Median hospital stay prior to death was 4 days (range 0-58). CONCLUSIONS: Patients, mostly young adults, who died from A(HIN1) influenza had a high frequency of one or more chronic diseases upon admission. Most died shortly after the health authorities initiated national influenza control measures.

OBJECTIVE: We aim to assess the opinions of Mexicans in the state of Tlaxcala on abortion and other topics concerning women's reproductive health and status in society. MATERIAL AND METHODS: We summarize opinions on abortion and women's roles in society and perform logit regressions to assess characteristics correlated with support for abortion rights. RESULTS: A majority of respondents were against a woman's right to abortion when asked generally, but when asked about specific circumstances, a majority supported the right to abortion in five of the nine hypothetical circumstances proposed. In multivariate analysis, age, education, religion, religious service attendance, and views regarding women's roles in society had significant effects on support for the right to abortion. CONCLUSIONS: Our results demonstrate that residents of Tlaxcala view abortion as a personal decision and support a woman's right to abortion in more circumstances than currently allowed under state law.

INTRODUCTION: The incidence of pregnancy in female sex workers (FSWs) living with HIV is not well characterized. METHODS: Current and former FSWs living with HIV and enrolled in a prospective cohort study in Mombasa, Kenya, were followed monthly to ascertain sexual behavior and underwent quarterly pregnancy testing. Pregnancies were considered planned, mistimed, or unwanted according to fertility desires and pregnancy intentions. Cox proportional hazards models were used to estimate hazard ratios (HRs) of the association between characteristics and incident pregnancy. RESULTS: Two hundred seventy-nine FSWs were eligible (October 2012-April 2017). Most women had a nonpaying, regular partner (83.2%, 232/279), were not using modern nonbarrier contraception (69.5%, 194/279), and did not desire additional children (70.6%, 197/279). Of 34 first incident pregnancies [5.8/100 person-years (p-y); 95% confidence interval (CI): 4.1 to 8.0], 91.2% (n = 31) were unintended. The incidences of planned (5.7/100 p-y, n = 3), mistimed (10.4/100 p-y, n = 9), and unwanted pregnancies (4.9/100 p-y, n = 22) were similar (P = 0.15). In univariable analysis, oral contraceptive pill use (versus no contraception), having a nonpaying, regular partner, transactional sex, vaginal washing, condomless sex, and higher sex frequency were associated with an increased pregnancy risk. Older age was associated with a lower pregnancy risk. In multivariable analysis, having a nonpaying, regular partner (adjusted HR 4.0, 95% CI: 1.2 to 14.1) and age ≥40 years (aHR 0.2, 95% CI: 0.0 to 0.9) remained significantly associated with a higher and lower pregnancy risk, respectively. CONCLUSION: In this cohort of HIV-positive FSWs, most pregnancies were unintended. Identifying FSWs' fertility desires and pregnancy intentions could facilitate efforts to increase contraceptive use and implement safer conception strategies.
