- Abstract
Background: The insulin-like growth factor (IGF) axis has been hypothesized to influence the rate of human immunodeficiency virus (HIV) disease progression. This premise is based largely on laboratory models showing that IGF-I stimulates thymic growth and increases lymphocyte numbers and that IGF-binding protein (IGFBP)-3 has an opposing effect, inhibiting hematopoietic stem cell development.Methods: We studied 1422 HIV-infected women enrolled in a large cohort that entailed semiannual follow-up (initiated in 1994). Baseline serum samples were tested for IGF-I and IGFBP-3 to determine their associations with incident clinical acquired immunodeficiency syndrome (AIDS) and CD4+ T cell count decline prior to April 1996 (before the era of highly active antiretroviral therapy [HAART]).Results: Low IGF-I levels (Ptrend= .02) and high IGFBP-3 levels (Ptrend= .02) were associated with rapid CD4+ T cell count decline. Only IGFBP-3, however, was significantly associated with AIDS incidence (hazard ratio for highest vs. lowest quartile, 2.65 [95% confidence interval, 1.30-5.42]; Ptrend= .02) in multivariable models.Conclusions: These findings suggest that serum levels of IGFBP-3 (and possibly IGF-I) are associated with the rate of HIV disease progression in women and, more broadly, that interindividual heterogeneity in the IGF axis may influence HIV pathogenesis. If correct, the IGF axis could be a target for interventions to slow HIV disease progression and extend the time before use of HAART becomes necessary. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective. To describe outcomes after treatment of cervical intraepithelial neoplasia (CIN) in women with HIV.Materials and Methods. Women in two prospective cohort studies, the Women's Interagency HIV Study (WIHS) and the HIV Epidemiology Research Study (HERS), were followed every 6 months after treatment of CIN using human papillomavirus (HPV) testing and cytology with colposcopy as indicated. Identification of CIN or a squamous intraepithelial lesion (SIL) within 6 months was defined as treatment failure and later disease as recurrence.Results. Follow-up was available for 170 HIV-seropositive and 15 HIV-seronegative women. Treatment failed in 84 (45%) women (79 HIV seropositive and 5 HIV seronegative). Failure was more likely in women with lower CD4 counts (CD4 < 200 cells/[mu]L: odds ratio [OR] = 2.96; 95% CI = 1.4-6.2) and detectable HPV DNA (OR 8.20; 95% CI = 1.8-37.4; p = .01). After successful treatment, recurrence-free probabilities at 1,2, 3, and 5 years were .79, .64, .49, and .34, respectively. HIV-seronegative women were less likely to recur than HIV-seropositive women (p = .03). In multivariable analysis of HIV-positive women, recurrence was more likely among women treated for CIN 2,3 (hazard ratio [HR] = 2.4; 95% CI = 1.4-4.8), those with CD4 count of less than 200 cells/[mu]L (HR = 2.9; 95% CI = 1.3-6.5) and those with HPV after treatment (HR 2.9; 95% CI = 1.4-6.1); oncogenic HPV was more strongly associated with recurrence than nononcogenic HPV (ptrend = .009). Most failures and recurrences were low grade, but one adenocarcinoma was diagnosed 4.2 years after therapy for CIN 1.Conclusion. Treatment failure and recurrence are common in women with HIV but are usually low grade. [ABSTRACT FROM AUTHOR]

- Abstract
ABSTRACT While international guidelines recommend integration of family planning (FP) and HIV services, limited research has been done to explore how healthcare providers perceive the feasibility and utility of integrated services. To address this gap, we administered a standardized questionnaire to 85 providers from 6 HIV clinics in Lusaka, Zambia, before (April-May 2018) and after (May-June 2019) implementing an enhanced model of FP/HIV service integration. We tested for differences in FP knowledge, attitudes and practices between the two time periods with tests appropriate for paired observations. The proportion of providers self-reporting direct provision of contraceptives increased significantly for several methods including oral contraceptives (14% vs. 26%, p = 0.03), injectables (9% vs. 25%, p < 0.001), implants (2% vs. 13%, p = 0.007) and intra-uterine devices (2% vs. 13%, p = 0.007). In-depth interviews were also conducted post-integration with 109 providers to solicit their feedback on the benefits and challenges of offering integrated services. While providers were highly supportive of integrated services, they identified several challenges including widespread belief in FP myths among female clients, the need to consult a male partner prior to starting FP, lack of trained staff and space, and frequent stockouts of contraceptives and equipment. Addressing these challenges will be critical in designing future services.

- Abstract
Young adults with HIV (YAHIV) may be particularly vulnerable to the impact of the COVID-19 pandemic. In this context, associated mitigation measures among YAHIV can adversely impact fragile social and economic systems. We examined the impact of the pandemic and related government-mandated restrictions among YAHIV in Kisumu, Kenya. Between April-May 2021, a cross-sectional survey was conducted among a convenience sample of YAHIV 18-25 years receiving HIV care in Kisumu, Kenya. The information collected included demographics, COVID-19 knowledge, protective measures, and the impact of the pandemic and related restrictions on their daily lives and well-being since the start of the pandemic (i.e., curfews, lockdowns, school/workplace closures). Responses were analyzed using descriptive statistics. Of 275 YAHIV: median age 22 years (IQR: 19-24 years); 178 (65%) female; 222 (81%) completed some secondary education or higher; 108 (39%) lived in an informal housing area. Awareness of COVID-19 was high (99%), mean knowledge score was 4.32 (SD: 0.93; range 1-5) and most reported taking protective measures. Overall, 193 (70%) reported they were affected by COVID-19 and associated restrictions. Almost half (49%) reported changes in a living situation; 24% living with different people, 11% had moved/relocated, and 5% were newly living on the street. Additionally, respondents reported increased verbal arguments (30%) and physical conflict (16%) at home with 8% reporting someone having used/threatened them with a weapon, 12% experiencing physical abuse, 7% being touched in a sexual way without permission, and 5% had forced sex. Impacts of the pandemic and related restrictions were felt across various aspects of YAHIV's lives, including disrupted living situations and increased exposure to verbal and physical conflict, including sexual violence. Interventions are needed to address the impact and potential negative long-term effects of the pandemic on YAHIV health and well-being., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Zech et al.

- Abstract
Introduction: We sought to characterize social and structural drivers of HIV vulnerability for transgender women (TGW) in Zimbabwe, where TGW are not legally recognized, and explore differences in vulnerability by feminine presentation., Methods: A secondary analysis was conducted with a sub-sample of participants recruited from a 2019 respondent-driven sampling survey that comprised men who have sex with men, TGW and genderqueer individuals assigned male sex at birth, from two cities in Zimbabwe. Survey questionnaires captured information related to socio-demographics, sexual and substance use behaviours, and social and structural barriers to HIV services. Secondary analyses were restricted to participants who identified as female, transfemale or transwomen (236/1538) and were unweighted. Descriptive statistics were used to calculate sample estimates and chi-square and Fisher's exact tests were used to assess differences in vulnerability by feminine presentation., Results: Among 236 TGW, almost half (45.3%) presented as feminine in the 6 months preceding the survey and 8.5% had ever used hormones to affirm their gender identities. Median age among TGW was 23 years (interquartile range: 20-26). Feminine presenting TGW in our sample had higher prevalence of arrest (15.9% vs. 3.9%), rejection by family/friends (38.3% vs. 14.0%), employment termination (11.2% vs. 3.9%), employment refusal (14.0% vs. 3.9%), denial of healthcare (16.8% vs. 2.3%), physical, sexual or verbal harassment or abuse (59.8% vs. 34.1%), alcohol dependence (32.7% vs. 12.4%), recent transactional sex with a male or TGW partner (30.8% vs. 13.3%) and recent non-injection drug use (38.3% vs. 20.2%) than non-feminine presenting TGW (all p-value <0.05)., Conclusions: Findings suggest that TGW, particularly feminine presenting TGW, experience social and structural inequities which may contribute to HIV vulnerability. Interventions aimed at addressing inequities, including trans competency training for providers and gender-affirming, psychosocial and legal support services for TGW, might mitigate risk., (© 2024 The Authors.

- Abstract
Background: Cameroon was among the most affected African countries during the first wave of the COVID-19 pandemic; however, the true prevalence of SARS-CoV-2 remains unknown., Methods: From October to December 2020, we conducted a cross-sectional, age-stratified SARS-CoV-2 seroepidemiological survey at 30 purposively selected community-based sites across Cameroon's 10 regional capitals, sampling 10,000 individuals aged 5 years or older. We employed a parallel SARS-CoV-2 antibody testing algorithm (WANTAI ELISA and Abbott Architect) to improve both the positive predictive value and negative predictive value of seroprevalence., Results: The overall weighted and adjusted seroprevalence of SARS-CoV-2 antibodies across the 10 urban capitals of Cameroon was 10.5% (95% CI: 9.1%-12.0%) among participants aged ≥5 years. Of the 9332 participants, 730 males (13.1%, 95% CI: 11.5%-14.9%) had SARS-CoV-2 antibodies compared to 293 females (8.0%, 95% CI: 6.8%-9.3%). Among those who reported a comorbidity at the time of testing, 15.8% (95% CI: 12.8%-19.4%) were seropositive. We estimated that over 2 million SARS-CoV-2 infections occurred in the 10 regional capitals of Cameroon between October and December 2020, compared to 21,160 cases officially reported at that time translating to one laboratory-confirmed case being reported for every 110 SARS-CoV-2 infections across the 10 urban capitals., Conclusion: This study's findings point to extensive and under-reported circulation of SARS-CoV-2 in Cameroon-an almost 100-fold more cases compared to the number of cases reported to the World Health Organization. This finding highlights the importance of conducting serosurveys, especially in settings where access to testing may be limited and to repeat such surveys as part of pandemic tracking., (© 2024 The Authors.

- Abstract
Background: People living with HIV (PLHIV) on effective antiretroviral therapy are living near-normal lives. Although they are less susceptible to AIDS-related complications, they remain highly vulnerable to non-communicable diseases. In this exploratory study of older PLHIV (OPLHIV) in Eswatini, we investigated whether epigenetic aging (i.e., the residual between regressing epigenetic age on chronological age) was associated with HIV-related parameters, and whether lifestyle factors modified these relationships. We calculated epigenetic aging focusing on the Horvath, Hannum, PhenoAge and GrimAge epigenetic clocks, and a pace of biological aging biomarker (DunedinPACE) among 44 OPLHIV in Eswatini., Results: Age at HIV diagnosis was associated with Hannum epigenetic age acceleration (EAA) (β-coefficient [95% Confidence Interval]; 0.53 [0.05, 1.00], p = 0.03) and longer duration since HIV diagnosis was associated with slower Hannum EAA (- 0.53 [- 1.00, - 0.05], p = 0.03). The average daily dietary intake of fruits and vegetables was associated with DunedinPACE (0.12 [0.03, 0.22], p = 0.01). The associations of Hannum EAA with the age at HIV diagnosis and duration of time since HIV diagnosis were attenuated when the average daily intake of fruits and vegetables or physical activity were included in our models. Diet and self-perceived quality of life measures modified the relationship between CD4
+ T cell counts at participant enrollment and Hannum EAA., Conclusions: Epigenetic age is more advanced in OPLHIV in Eswatini in those diagnosed with HIV at an older age and slowed in those who have lived for a longer time with diagnosed HIV. Lifestyle and quality of life factors may differentially affect epigenetic aging in OPLHIV. To our knowledge, this is the first study to assess epigenetic aging in OPLHIV in Eswatini and one of the few in sub-Saharan Africa., (© 2024. The Author(s).)- Published

- Abstract
Objectives: To measure HIV and Hepatitis B virus (HBV) prevalence and associated risk behaviors among men who have sex with men (MSM) and transgender women/genderqueer individuals (TGW/GQ) in Zimbabwe., Methods: We conducted a biobehavioral survey using respondent-driven sampling (RDS) among adult MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe in 2019. Participants completed a questionnaire and underwent testing for HIV and HBV., Results: Overall, 1,510 (Harare: 694, Bulawayo 816) participants were enrolled and consented to testing; 3.8 % (58) tested positive for HBV, 22.5 % (339) tested positive for HIV, and 2.2 % (33) tested positive for both HIV and HBV. HBV prevalence was higher among participants with HIV compared to HIV-negative participants (9.7 % vs. 2.1 %, p < 0.0001). Overall, HBV prevalence was not statistically different between MSM and TGW/GQ (3.7 % vs 4.5 %, p = 0.49) nor between Harare and Bulawayo (3.3 % vs 4.3 %, p = 0.33)., Conclusions: Our survey demonstrates the prevalence of HBV among MSM and TGW/GQ is lower than other estimates of HBV among MSM in Africa but remains high among our survey population living with HIV highlighting the need to expand HBV testing and treatment services, especially among people with HIV in Zimbabwe., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 Published by Elsevier Ltd.)

- Abstract
To better understand male and female sexual partnerships among men who have sex with men (MSM), we used data from a 2019 biobehavioral survey among MSM in Harare and Bulawayo, Zimbabwe to conduct bivariate analyses and multivariable logistic regression to determine whether sociodemographic characteristics and HIV-related factors were associated with having both male and female sexual partnerships within the last 6 months. Of included MSM (N = 1143), 31% reported both male and female partnerships in the last 6 months. Being married/cohabiting (adjusted odds ratio (aOR) = 8.58, 95% confidence interval (CI) = 4.92-14.95) or separated/divorced/widowed (aOR = 1.96, 95% CI = 1.24-3.08) vs. being single, and hazardous alcohol consumption (aOR = 1.58, 95% CI 1.19-2.09) were associated with higher odds of having both male and female recent partnerships. Being aged 35 + vs. 18-24 (aOR = 0.50, 95% CI = 0.31-0.81), condomless receptive anal intercourse at last sex with the main male partner (aOR = 0.43, 95% CI = 0.26-0.74), and positive HIV status (aOR = 0.46, 95% CI = 0.31-0.67) were associated with lower odds of recent male and female partnerships. MSM in Harare who reported harassment/abuse (aOR = 3.16, 95% CI = 1.72-5.79) had higher odds of both male and female partnerships than MSM in Bulawayo reporting harassment/abuse. The prevalence of both male and female recent partnerships (31%) was lower among MSM in this survey than in other biobehavioral surveys of MSM in sub-Saharan Africa. Findings suggest that MSM with recent male and female partnerships compared to MSM with only male recent partners have lower odds of positive HIV status and participate in behaviors that lower HIV risk; however, the direction of these relationships cannot be determined due to the cross-sectional nature of the data. The findings also suggest a possible connection between experiences of stigma of MSM behavior and not having both male and female partnerships that warrants further exploration. Accessible, stigma-free HIV testing and education programming that considers the potential overlap between the MSM and general populations via both male and female partnerships and the associated behaviors could be a key component of HIV elimination in Zimbabwe., (© 2024.

- Abstract
Background: People living with HIV (PLHIV) on effective antiretroviral therapy (ART) are living near-normal lives. Although they are less susceptible to AIDS-related complications, they remain highly vulnerable to non-communicable diseases (NCD). In this exploratory study of older PLHIV (OPLHIV) in Eswatini, we investigated whether biological aging ( i.e. , the difference between epigenetic age and chronological age, termed 'epigenetic age acceleration [EAA]') was associated with HIV-related parameters, and whether lifestyle factors modified these relationships. We calculated EAA focusing on the second-generation epigenetic clocks, PhenoAge and GrimAge, and a pace of aging biomarker (DunedinPACE) among 44 OPLHIV in Eswatini., Results: Among participants, the PhenoAge clock showed older epigenetic age (68 years old [63, 77]) but a younger GrimAge epigenetic age (median=56 years old [interquartile range=50, 61]) compared to the chronological age (59 years old [54, 66]). Participants diagnosed with HIV at an older age showed slower DunedinPACE (β-coefficient [95% Confidence Interval]; -0.02 [-0.04, -0.01], p =0.002) and longer duration since HIV diagnosis was associated with faster DunedinPACE (0.02 [0.01, 0.04], p =0.002). The average daily dietary intake of fruits and vegetables was associated with faster DunedinPACE (0.12 [0.03, 0.22], p =0.01) and modified the relationship between HIV status variables (number of years living with HIV since diagnosis, age at HIV diagnosis, CD4
+ T cell counts) and PhenoAge EAA, and DunedinPACE., Conclusions: Biological age is accelerated in OPLHIV in Eswatini, with those living with HIV for a longer duration at risk for faster biological aging. Lifestyle factors, especially healthier diets, may attenuate biological aging in OPLHIV. To our knowledge, this is the first study to assess biological aging in Eswatini and one of the few in sub-Saharan Africa., Competing Interests: Declaration of Competing Interest The authors declare they have no known competing financial or personal interests that could appear to influence the findings reported in this manuscript.- Published

- Abstract
Background: We designed and implemented an enhanced model of integrating family planning (FP) into existing HIV treatment services at 6 health facilities in Lusaka, Zambia., Methods: The enhanced model included improving FP documentation within HIV monitoring systems, training HIV providers in FP services, offering contraceptives within the HIV clinic, and facilitated referral to community-based distributors. Independent samples of women living with HIV (WLHIV) aged ≥16 years were interviewed before and after intervention and their clinical data abstracted from medical charts. Logistic regression models were used to assess differences in key outcomes between the 2 periods., Results: A total of 629 WLHIV were interviewed preintervention and 684 postintervention. Current FP use increased from 35% to 49% comparing the pre- and postintervention periods ( P = 0.0025). Increased use was seen for injectables (15% vs. 25%, P < 0.0001) and implants (5% vs. 8%, P > 0.05) but not for pills (10% vs. 8%, P < 0.05) or intrauterine devices (1% vs. 1%, P > 0.05). Dual method use (contraceptive + barrier method) increased from 8% to 18% ( P = 0.0003), whereas unmet need for FP decreased from 59% to 46% ( P = 0.0003). Receipt of safer conception counseling increased from 27% to 39% ( P < 0.0001). The estimated total intervention cost was $83,293 (2018 USD)., Conclusions: Our model of FP/HIV integration significantly increased the number of WLHIV reporting current FP and dual method use, a met need for FP, and safer conception counseling. These results support continued efforts to integrate FP and HIV services to improve women's access to sexual and reproductive health services., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
In Africa, rapid testing for recent HIV infection (RTRI) is being scaled up; however, use of the recent infection testing algorithm (RITA), which uses viral load (VL) to confirm RTRI-recent infections, is not a widespread practice. We present results of recently acquired HIV infections among men who have sex with men (MSM), transgender women, and genderqueer (TGW/GQ) individuals with newly diagnosed HIV infection in Zimbabwe as per the national approach (RTRI) and applying a RITA. In 2019, 1,538 MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe were recruited to participate in a biobehavioral survey using respondent-driven sampling. Consenting participants received HIV testing and all HIV-positive specimens were tested with the RTRI Asanté HIV-1 Rapid Recency Assay, and for VL and CD4 count. RTRI-recent participants with unsuppressed VL (≥1,000 copies/mL) were classified as RITA-recent. Descriptive statistics were used to summarize results among RTRI-recent and RITA-recent participants. Among those tested for HIV (1,511/1,538), 22.5% (340/1,511) tested positive and of those, 55.0% (187/340) self-reported an HIV-negative or unknown status. Among these, 8.6% (16/187) were classified as RTRI-recent and 91.4% (171/187) were classified as RTRI-long term. After accounting for VL, RITA-recency was 1.1% (2/187). Two of 16 (12.5%) RTRI-recent infections were RITA-recent. VL among RITA-recent cases were 9,052 copies/mL and 40,694 copies/mL and both had CD4 counts <500. Data highlight misclassification of recent infections among MSM and TGW/GQ with newly diagnosed HIV infection using RTRI. With the incorporation of VL, >85% of RTRI-recent cases were reclassified as RITA-long term. True characterization of recent infections may not be possible without VL testing, which remains challenging in resource-limited settings.

- Abstract
Key populations including men who have sex with men (MSM), female sex workers, people who inject drugs, transgender persons, and prisoners account for nearly 50% of new HIV infections globally. To inform the HIV response and monitor trends in HIV prevalence and incidence among key populations, countries have increased efforts to implement biobehavioral surveys (BBS) with these groups as part of routine surveillance. Yet the marginalized nature of populations participating in a BBS requires contextually acceptable and appropriate strategies for effective implementation. We conducted a formative assessment to inform the first BBS conducted with MSM and others assigned male who have sex with men (OAMSM) in Zimbabwe, where same-sex sexual behaviors are illegal and highly stigmatized and describe applications of our findings. Qualitative data were collected through four focus groups with 32 MSM/OAMSM and 25 in-depth interviews (15 MSM/OAMSM, 10 service providers/gatekeepers) from December 2018 to January 2019. Rapid assessment techniques were employed including rapid identification of themes from audio recordings and review of detailed field notes and memos to identify key themes. Findings from this assessment included contextually relevant considerations including behaviors and terminology to avoid when working with MSM/OAMSM in Zimbabwe, appropriate compensation amounts for survey participation, proposed data collection sites, and differences in sexual openness, marital status, and networks among younger and older MSM/OAMSM. Participants also reported strong network ties suggesting respondent-driven sampling-a peer chain referral approach-to be an appropriate recruitment method in this context. Taken together, these findings highlighted key considerations and strategies for implementation to ensure the subsequent BBS in Zimbabwe was both acceptable and appropriate. These results and applications of these results are important for informing surveillance efforts and broader HIV-related engagement efforts among MSM/OAMSM in Zimbabwe as well as in other contextually similar countries in Southern Africa., Competing Interests: GM is an editor with PLOS ONE and PLOS GLOBAL HEALTH.

- Abstract
Though stigma is a recognized contributor to the disproportionate HIV burden among sexual and gender minorities (SGM) in sub-Saharan Africa, data describing this association among Zimbabwean SGM are limited. We examined relationships between SGM stigma and HIV and the potential for social cohesion to moderate the association among Zimbabwean men who have sex with men, transgender women, and genderqueer individuals. Consenting participants (n = 1511) recruited through respondent-driven sampling for a biobehavioral survey in Harare and Bulawayo completed structured interviews and received HIV testing. Reported SGM stigma was common (68.9% in Harare and 65.3% in Bulawayo) and associated with HIV infection in Harare (adjusted prevalence ratio [aPR] = 1.82, 95% confidence interval [CI] = 1.27-2.62) and Bulawayo (aPR = 1.51, 95% CI = 1.15-2.00) in relative risk regression. Social cohesion did not moderate these relationships. Findings demonstrate stigma's association with HIV vulnerability among Zimbabwean SGM, highlighting the need for stigma-mitigation to reduce HIV transmission in this population., (© 2022.

- Abstract
Introduction: Achieving optimal HIV outcomes, as measured by global 90-90-90 targets, that is awareness of HIV-positive status, receipt of antiretroviral (ARV) therapy among aware and viral load (VL) suppression among those on ARVs, respectively, is critical. However, few data from sub-Saharan Africa (SSA) are available on older people (50+) living with HIV (OPLWH). We examined 90-90-90 progress by age, 15-49 (as a comparison) and 50+ years, with further analyses among 50+ (55-59, 60-64, 65+ vs. 50-54), in 13 countries (Cameroon, Cote d'Ivoire, Eswatini, Ethiopia, Kenya, Lesotho, Malawi, Namibia, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe)., Methods: Using data from nationally representative Population-based HIV Impact Assessments, conducted between 2015and 2019, participants from randomly selected households provided demographic and clinical information and whole blood specimens for HIV serology, VL and ARV testing. Survey weighted outcomes were estimated for 90-90-90 targets. Country-specific Poisson regression models examined 90-90-90 variation among OPLWH age strata., Results: Analyses included 24,826 HIV-positive individuals (15-49 years: 20,170; 50+ years: 4656). The first, second and third 90 outcomes were achieved in 1, 10 and 5 countries, respectively, by those aged 15-49, while OPLWH achieved outcomes in 3, 13 and 12 countries, respectively. Among those aged 15-49, women were more likely to achieve 90-90-90 targets than men; however, among OPLWH, men were more likely to achieve first and third 90 targets than women, with second 90 achievement being equivalent. Country-specific 90-90-90 regression models among OPLWH demonstrated minimal variation by age stratum across 13 countries. Among OLPWH, no first 90 target differences were noted by age strata; three countries varied in the second 90 by older age strata but not in a consistent direction; one country showed higher achievement of the third 90 in an older age stratum., Conclusions: While OPLWH in these 13 countries were slightly more likely than younger people to be aware of their HIV-positive status (first 90), this target was not achieved in most countries. However, OPLWH achieved treatment (second 90) and VL suppression (third 90) targets in more countries than PLWH <50. Findings support expanded HIV testing, prevention and treatment services to meet ongoing OPLWH health needs in SSA., (© 2022 The Authors.

- Abstract
Background: Due to concerns about the effects of the coronavirus disease 2019 (COVID-19 pandemic on health services, we examined its effects on human immunodeficiency virus (HIV) services in sub-Saharan Africa., Methods: Quarterly data (Q1, 10/2019-12/2019; Q2, 1/2020-3/2020; Q3, 4/2020-6/2020; Q4, 7/2020-9/2020) from 1059 health facilities in 11 countries were analyzed and categorized by stringency of pandemic measures. We conducted a difference-in-differences assessment of HIV service changes from Q1-Q2 to Q3-Q4 by higher vs lower stringency., Results: There was a 3.3% decrease in the number HIV tested from Q2 to Q3 (572 845 to 553 780), with the number testing HIV-positive declining by 4.9% from Q2 to Q3. From Q3 to Q4, the number tested increased by 10.6% (612 646), with an increase of 8.8% (23 457) in the number testing HIV-positive with similar yield (3.8%). New antiretroviral therapy (ART) initiations declined by 9.8% from Q2 to Q3 but increased in Q4 by 9.8%. Across all quarters, the number on ART increased (Q1, 419 028 to Q4, 476 010). The number receiving viral load (VL) testing in the prior 12 months increased (Q1, 255 290 to Q4, 312 869). No decrease was noted in VL suppression (Q1, 87.5% to Q4, 90.1%). HIV testing (P < .0001) and new ART initiations (P = .001) were inversely associated with stringency., Conclusions: After initial declines, rebound was brisk, with increases noted in the number HIV tested, newly initiated or currently on ART, VL testing, and VL suppression throughout the period, demonstrating HIV program resilience in the face of the COVID-19 crisis., (© The Author(s) 2021.

- Abstract
People who inject drugs (PWID) are at a high risk for HIV. We conducted an evaluation of socio-demographic factors associated with injecting and sexual behaviour among PWID who had two or more visits at a drug outreach clinic in Cairo, Egypt from 2013 to 2017. Routinely collected information on socio-demographics and HIV risk behaviours were abstracted from client records. Bivariate analysis and logistic regression were conducted to evaluate associations between socio-demographics and HIV risk factors. All PWID who tested HIV-positive at the initial visit were excluded from analyses. PWID who were married were more likely to share needles or syringes in the last month of their baseline visit [adjusted odds ratio (aOR) = 4.3, 95% confidence interval (CI) = 1.4-13.1] as were unemployed PWID [aOR = 3.9, 95% CI = 1.5-10.3]. Married PWID were less likely to discontinue sharing needles/syringes [aOR = 0.4, 95% CI = 0.2-0.8] as were those living outside of the Shobra, downtown, and Imbabah districts within Greater Cairo [aOR = 0.2, 95% CI = 0.1-0.5]. No significant associations were found between socio-demographics and number of sex partners in the six months prior to the initial visit. At follow-up visit, 4.4% tested HIV-positive for an incidence rate of 3.9 per 100 person years. Sociodemographic factors should be considered when designing preventive services for PWID.

- Abstract
Background: Globally, men who have sex with men (MSM), transgender women, and genderqueer individuals are at greater risk for HIV than the general population although little data are available from these groups in Zimbabwe, a country with a national adult HIV prevalence of 12·9%. We aimed to examine progress towards the UNAIDS 90-90-90 treatment targets and factors associated with meeting the targets among a sample of MSM, transgender women, and genderqueer individuals in Zimbabwe., Methods: In this cross-sectional survey in 2019, we used respondent-driven sampling to identify MSM, transgender women, and genderqueer individuals aged at least 18 years to participate in a biobehavioural survey in Harare and Bulawayo, Zimbabwe. Participants were eligible to participate if they were assigned male at birth; had engaged in anal or oral sex with a man in the past 12 months; resided in Harare or Bulawayo for at least 1 month; spoke English, Shona, or Ndebele; provided written informed consent; and were in possession of a valid recruitment coupon if applicable. Enrolled participants completed a questionnaire and underwent HIV testing, and off-site viral load testing was done on all HIV-positive samples. Unweighted bivariate analyses and multivariable logistic regression models were used to evaluate the association of sociodemographic, behavioural, and other factors with HIV-positive status awareness among MSM, transgender women, and genderqueer individuals, and with viral load suppression among MSM. Analyses were done firstly using self-reported information and then by classifying those with a viral load of less than 200 copies per mL as being aware of their status and on treatment (viral load recategorisation)., Findings: Among MSM, 248 (21%; 95% CI 19-24) of 1176 tested positive for HIV. Of those who tested positive, based on self-report, 119 (48%; 95% CI 42-54) reported knowing their HIV status, of whom 112 (94%; 88-98) reported using antiretroviral therapy (ART), of whom 89 (79%; 71-87) had viral load suppression. Based on viral load recategorisation, 180 (73%; 67-78) of 248 MSM testing HIV positive reported knowing their HIV status, of whom 174 (97%; 93-99) reported using ART, of whom 151 (87%; 81-91) had viral load suppression. 92 (28%; 23-33) of 335 transgender women and genderqueer individuals tested positive for HIV. Based on self-reports from these individuals 34 (37%; 27-48) of 92 participants reported knowing their HIV status, of whom 31 (91%; 76-98) reported using ART, of whom 27 (87%; 70-96%) had viral load suppression. Based on viral load recategorisation of data from transgender women and genderqueer participants, 53 (58%; 47-58) of 92 reported awareness of their HIV status, of whom 50 (94%; 84-99) reported using ART, of whom 46 (92%; 81-98) had viral load suppression. HIV-positive MSM aged 18-24 years had lower odds of being aware of their status than those aged at least 35 years (adjusted odds ratio [aOR] 0·34; 95% CI 0·13-0·92), as did HIV-positive MSM aged 25-34 years (aOR 0·26; 0·12-0·56). HIV-positive MSM aged 18-24 years also had a lower odds of having viral load suppression than those aged 35 years and older (aOR 0·35; 0·16-0·78), as did those aged 25-34 years (aOR 0·36; 0·19-0·67). No factors were significantly associated with awareness among transgender women and genderqueer individuals in multivariable models., Interpretation: Our survey showed that HIV prevalence was high and the largest difference between our results and the 90-90-90 treatment targets was in HIV status awareness, indicating the need for improvements in engaging MSM (especially young MSM), transgender women, and genderqueer individuals in HIV testing services., Funding: US President's Emergency Plan for AIDS Relief through the US Centers for Disease Control and Prevention., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2022 Elsevier Ltd.

- Abstract
Background: Syphilis increases human immunodeficiency virus (HIV) acquisition risk and impacts the immunologic and virologic response among people living with HIV (PLHIV). We assessed the prevalence of active or current syphilis and HIV/syphilis and their correlates among men who have sex with men (MSM), transwomen, and genderqueer (TGW/GQ) individuals in Zimbabwe., Methods: Among a respondent-driven sample of MSM and TGW/GQ who were tested for HIV and syphilis in Harare and Bulawayo, Zimbabwe in 2019 (n = 1511), multiple logistic regression was used to assess correlates of active syphilis. Unadjusted logistic regression was used among PLHIV (n = 340) due to small sample size. All analyses were unweighted as data did not reach convergence for HIV., Results: Prevalence of active syphilis overall and among PLHIV was 5.5% and 10.1%, respectively, in Harare, and 5.6% and 11.0%, respectively, in Bulawayo. Participants were more likely to have active syphilis if they were PLHIV (adjusted odds ratio [aOR], 2.2; 95% confidence interval [CI], 1.4-3.6), aged 25-34 years (aOR, 2.2 years; 95% CI, 1.3-3.8 years; reference, 18-24 years), or self-report sexually transmitted infection symptoms (aOR, 1.8; 95% CI, 1.1-3.0). Compared with Bulawayo TGW/GQ, MSM in Harare (aOR, 0.2; 95% CI, 0.1-0.5) and Bulawayo (aOR, 0.2; 95% CI, 0.1-0.4), and TGW/GQ in Harare (aOR, 0.2; 95% CI, 0.1-0.6) were less likely to have active syphilis. Among PLHIV, coinfection was 13.0% among TGW/GQ and 9.7% among MSM. Odds of coinfection were higher for those aged 25 to 34 years (OR, 3.7 years; 95% CI, 1.2-11.1 years) and lower among Harare MSM (OR, 0.2; 95% CI, 0.1-0.7), Bulawayo MSM (OR, 0.1; 95% CI, 0.0-0.4), and Harare TGW/GQ (OR, 0.1; 95% CI, 0.0-0.4) compared with Bulawayo TGW/GQ., Conclusions: Findings highlight a high burden of syphilis among MSM and TGW/GQ and underscore the importance of HIV/syphilis detection and improved service delivery for these groups., Competing Interests: Conflict of Interest: None declared., (Copyright © 2021 The Author(s).

- Abstract
Introduction: Zimbabwe is scaling up pre-exposure prophylaxis (PrEP) for key populations, including men who have sex with men (MSM) and transgender women (TGW). To assess implementation and inform HIV programming, we evaluated gaps in PrEP awareness, uptake and use, and correlates of awareness and uptake among a sample of MSM, TGW and genderqueer individuals (GQ) in Harare and Bulawayo, Zimbabwe., Methods: Respondent-driven sampling was used to recruit 1194 MSM and 344 TGW/GQ aged ≥18 to participate in a cross-sectional survey assessing HIV-related outcomes in 2019. Consenting participants completed a questionnaire on socio-demographic information, sexual risk practices and engagement in HIV services and underwent HIV testing. Descriptive statistics were used to assess the PrEP cascade. Multiple logistic regression models were used to identify factors associated with PrEP awareness and uptake among HIV-negative participants. Data were unweighted as the sample did not reach convergence on key estimates., Results: Among the 1167 HIV-negative participants, most (79.2%) were MSM compared to TGW/GQ (20.8%). Median age was 24 years. Overall, 45.8% were aware of PrEP and of those, 31.3% had ever taken PrEP. Most (71.1%) reporting never taking PrEP were willing to start PrEP; the main reasons for never starting PrEP included not knowing where to access it (24.8%) and fearing side effects (20.4%). Among those who had ever taken PrEP, 74.9% had taken PrEP in the last 6 months; of these, 42.4% had taken PrEP the day of or day preceding the survey. Side effects represented the most common (59.5%) reason for discontinuing PrEP. MSM (adjusted odds ratio [aOR]: 2.5, 95% confidence interval [CI]: 1.8-3.6) and TGW/GQ in Harare (aOR: 3.1, 95% CI: 2.1-4.7), and TGW/GQ in Bulawayo (aOR: 2.4, 95% CI: 1.1-5.3) had higher awareness of PrEP than MSM in Bulawayo. Overall, TGW/GQ were more likely to have ever taken PrEP compared to MSM (aOR: 1.6, 95% CI: 1.01-2.4)., Conclusions: Findings emphasize the need for tailored interventions to promote PrEP among key populations. As HIV programs in Zimbabwe continue to expand PrEP services, these data, including barriers to starting and continuing PrEP, can inform strategies to address gaps along the PrEP cascade., (© 2022 The Authors.

- Abstract
Zimbabwe has made large strides in addressing HIV. To ensure a continued robust response, a clear understanding of costs associated with its HIV program is critical. We conducted a cross-sectional evaluation in 2017 to estimate the annual average patient cost for accessing Prevention of Mother-To-Child Transmission (PMTCT) services (through antenatal care) and Antiretroviral Treatment (ART) services in Zimbabwe. Twenty sites representing different types of public health facilities in Zimbabwe were included. Data on patient costs were collected through in-person interviews with 414 ART and 424 PMTCT adult patients and through telephone interviews with 38 ART and 47 PMTCT adult patients who had missed their last appointment. The mean and median annual patient costs were examined overall and by service type for all participants and for those who paid any cost. Potential patient costs related to time lost were calculated by multiplying the total time to access services (travel time, waiting time, and clinic visit duration) by potential earnings (US$75 per month assuming 8 hours per day and 5 days per week). Mean annual patient costs for accessing services for the participants was US$20.00 [standard deviation (SD) = US$80.42, median = US$6.00, range = US$0.00-US$12,18.00] for PMTCT and US$18.73 (SD = US$58.54, median = US$8.00, range = US$0.00-US$ 908.00) for ART patients. The mean annual direct medical costs for PMTCT and ART were US$9.78 (SD = US$78.58, median = US$0.00, range = US$0.00-US$ 90) and US$7.49 (SD = US$60.00, median = US$0.00) while mean annual direct non-medical cost for US$10.23 (SD = US$17.35, median = US$4.00) and US$11.23 (SD = US$25.22, median = US$6.00, range = US$0.00-US$ 360.00). The PMTCT and ART costs per visit based on time lost were US$3.53 (US$1.13 to US$8.69) and US$3.43 (US$1.14 to US$8.53), respectively. The mean annual patient costs per person for PMTCT and ART in this evaluation will impact household income since PMTCT and ART services in Zimbabwe are supposed to be free., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background : Antiretroviral therapy (ART) has decreased HIV-related morbidity and mortality and increased life expectancy of people living with HIV (PLHIV). Globally, the number of older PLHIV (OPLHIV; ≥50 years) is growing and predicted to increase substantially in coming years. In sub-Saharan Africa, where the majority of OPLHIV reside, there are limited data on the health and well-being of OPLHIV. Methods : We conducted an exploratory descriptive study that included structured interviews with 50 OPLHIV receiving ART at an outpatient HIV clinic in Eswatini and in-depth qualitative interviews (IDIs) with a sub-set of ten participants to elicit their experiences of living with HIV as an older adult, including quality of life, physical health, and mental health. Quantitative analyses were performed to obtain both descriptive statistics and cross-tabulations. A thematic analysis of IDI narratives was conducted based on three levels of the socio-ecological model to identify sub-themes and response patterns. Results : All study participants were virally suppressed. Self-reported non-communicable disease (NCD) risk factors and markers were common, with 40% ( n = 20) reporting being current or former smokers, 0% consuming the recommended servings of fruits and vegetables per day, and 57% ( n = 28 of 49 reporting screening) reporting having hypertension. However, the majority (88%; 44 of 50) had sufficient physical activity; most of the activity was in the work domain. Slightly more than one-third (38%; 13 of 34 tested) had a high random blood sugar level. Barriers to living with HIV were primarily structural (food insecurity, unemployment, access to transportation and health care). Conclusions : OPLHIV should be screened for NCDs, and services for NCDs should ideally be integrated with HIV services. While all participants had controlled HIV, this study highlights the need for strategies that facilitate OPLHIV's HIV service utilisation. With the increasing numbers of OPLHIV, these issues cannot be ignored.

Management of foot and ankle trauma continues to evolve and change. It is important to be informed about the latest challenges and controversies in management of these injuries, which include ankle fractures, calcaneus fractures, Lisfranc injuries, and Jones fracture. Important concepts related to ankle fracture are the changing indications for surgery, utilization of stress radiographs, the role of arthroscopy, repair of the deltoid ligament, fixation of the posterior malleolus, and diagnosis and treatment of syndesmotic injuries. Regarding calcaneus fractures, discussion revolves around defining indications for fixation, factors that influence outcomes, less invasive approaches versus traditional extensile exposures, and the nature of the constant fragment. With Lisfranc injuries, the orthopaedic surgeon should be aware of fixation methods as well as the issue of fixation versus fusion. Discussion of Jones fracture should include evaluation of indications and different fixation techniques.

- Abstract
Background. The aim of this study was to determine the accuracy of ankle arthroscopy as a means for diagnosing syndesmotic reduction or malreduction and to determine anatomical landmarks for diagnosis. Methods. Six matched-pair cadavers (n = 12) with through-knee amputations were studied. Component parts of the syndesmosis and distal 10 cm of the interosseous membrane (IOM) were sectioned in each. The 12 specimens were divided into 2 groups: 6 specimens in the in-situ group fixed with suture button technique and 6 specimens in the malreduced group rigidly held with a 3.5-mm screw. Specimens were randomized to undergo diagnostic arthroscopy by 3 fellowship-trained foot and ankle orthopaedic surgeons in a blinded fashion. Surgeons were asked to determine if the syndesmosis was reduced or malreduced and provide arthroscopic measurements of their findings. Results. Of 36 arthroscopic evaluations, 34 (94%) were correctly diagnosed. Arthroscopic measurement of 3.5 mm diastasis or greater at the anterior aspect of the distal tibiofibular syndesmosis correlated with a posteriorly malreduced fibula. Arthroscopic evaluation of the Anterior inferior tibiofibular ligament (AITFL), IOM, Posterior inferior tibiofibular ligament (PITFL), lateral fibular gutter, and the tibia/fibula relationship were found to be reliable landmarks in determining syndesmotic reduction. An intraclass correlation coefficient (ICC) for interrater reliability of 1.00 was determined for each of these landmarks between 2 surgeons (P < .001). The ICCs between 2 surgeons' measurements and the computed tomography measurements were found to be 0.896 (P value < .001). Conclusions. Ankle arthroscopy is a reliable method to assess syndesmotic relationship when reduced in situ or posteriorly malreduced 10 mm. Levels of Evidence: Level V: Cadaveric.

- Abstract
Two theories exist in the development of central or transfer metatarsalgia. First, as the severity of hallux valgus increases, there is mechanical overload of the second metatarsal. Second, increased relative lesser metatarsal length is thought to contribute to metatarsalgia. It is imperative, in the treatment of first ray disorders (hallux valgus or hallux rigidus), to not overshorten the first ray when addressing the first ray pathologic condition. Treatment of metatarsalgia in the setting of failed hallux valgus correction can be treated with both conservative and surgical options., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Objective: Inactive lifestyles contribute to health problems and premature death and are influenced by the physical environment. The primary objective of this study was to quantify patterns of physical inactivity in New York City and the United States by combining data from surveys and accelerometers., Methods: We used Poisson regression models and self-reported survey data on physical activity and other demographic characteristics to predict accelerometer-measured inactivity in New York City and the United States among adults aged ≥18. National data came from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Surveys. New York City data came from the 2010-2011 New York City Physical Activity and Transit survey., Results: Self-reported survey data indicated no significant differences in inactivity between New York City and the United States, but accelerometer data showed that 53.1% of persons nationally, compared with 23.4% in New York City, were inactive ( P < .001). New Yorkers reported a median of 139 weekly minutes of transportation activity, compared with 0 minutes nationally. Nationally, 50.0% of self-reported activity minutes came from recreation activity, compared with 17.5% in New York City. Regression models indicated differences in the association between self-reported minutes of transportation and recreation and accelerometer-measured inactivity in the 2 settings., Conclusions: The prevalence of physical inactivity was higher nationally than in New York City. The largest difference was in walking behavior indicated by self-reported transportation activity. The study demonstrated the feasibility of combining accelerometer and survey measurement and that walkable environments promote an active lifestyle.

- Abstract
Avascular necrosis (AVN) following rotational ankle fractures is most commonly described in the talus; however, it can also occur in the tibial plafond. These sequelae of ankle fractures are rarely described in the literature. Diagnosis of AVN is best confirmed with MRI of the involved extremity. Treatment options range from conservative treatments such as observation and limited weight-bearing to surgical management including percutaneous drilling, ankle arthrodesis, and total ankle arthroplasty. More research is needed to further identify patients at high risk for developing these sequelae of ankle fractures and to aid in the treatment and surgical decision-making process., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: To obtain adequate fixation in treating Lisfranc soft tissue injuries, the joint is commonly stabilized using multiple transarticular screws; however iatrogenic injury is a concern. Alternatively, two parallel, longitudinally placed plates, can be used to stabilize the 1st and 2nd tarsometatarsal joints; however this may not provide adequate stability along the Lisfranc ligament. Several biomechanical studies have compared earlier methods of fixation using plates to the standard transarticular screw fixation method, highlighting the potential issue of transverse stability using plates. A novel dorsal plate is introduced, intended to provide transverse and longitudinal stability, without injury to the articular cartilage., Methods: A biomechanical cadaver model was developed to compare the fixation stability of a novel Lisfranc plate to that of traditional fixation, using transarticular screws. Thirteen pairs of cadaveric specimens were tested intact, after a simulated Lisfranc injury, and then following implant fixation, using one method of fixation randomly assigned, on either side of each pair. Optical motion tracking was used to measure the motion between each of the following four bones: 1st metatarsal, 2nd metatarsal, 1st cuneiform, and 2nd cuneiform. Testing included both cyclic abduction loading and cyclic axial loading., Results: Both the Lisfranc plate and screw fixation method provided stability such that the average 3D motions across the Lisfranc joint (between 2nd metatarsal and 1st cuneiform), were between 0.2 and 0.4mm under cyclic abduction loading, and between 0.4 and 0.5mm under cyclic axial loading. Comparing the stability of fixation between the Lisfranc plate and the screws, the differences in motion were all 0.3mm or lower, with no clinically significant differences (p>0.16)., Conclusions: Diastasis at the Lisfranc joint following fixation with a novel plate or transarticular screw fixation were comparable. Therefore, the Lisfranc plate may provide adequate support without risk of iatrogenic injury to the articular cartilage., (Copyright © 2017 European Foot and Ankle Society. Published by Elsevier Ltd.

- Abstract
Background: A rapid increase of Medicaid expenditures has been a serious concern, and housing stability has been discussed as a means to reduce Medicaid costs. A program evaluation of a New York City supportive housing program has assessed the association between supportive housing tenancy and Medicaid savings among New York City housing program applicants with serious mental illness and chronic homelessness or dual diagnoses of mental illness and substance use disorder, stratified by distinctive Medicaid expenditure patterns., Methods: The evaluation used matched data from administrative records for 2827 people. Sequence analysis identified 6 Medicaid expenditure patterns during 2 years prior to baseline among people placed in the program (n = 737) and people eligible but not placed (n = 2090), including very low Medicaid coverage, increasing Medicaid expenditure, low, middle, high, and very high Medicaid expenditure patterns. We assessed the impact of the program on Medicaid costs for 2 years post-baseline via propensity score matching and bootstrapping., Results: The housing program was associated with Medicaid savings during 2 years post-baseline (-$9526, 95% CI = -$19,038 to -$2003). Stratified by Medicaid expenditure patterns, Medicaid savings were found among those with very low Medicaid coverage (-$15,694, 95% CI = -$35,926 to -$7983), increasing Medicaid expenditures (-$9020, 95% CI = -$26,753 to -$1705), and high Medicaid expenditure patterns (-$14,450, 95% CI = -$38,232 to -$4454). Savings were largely driven by shorter psychiatric hospitalizations in the post-baseline period among those placed., Conclusions: The supportive housing program was associated with Medicaid savings, particularly for individuals with very low Medicaid coverage, increasing Medicaid expenditures, and high Medicaid expenditures pre-baseline.

- Abstract
The health of people ever incarcerated in New York City (NYC) jails during 2001 to 2005 was characterized by matching jail, shelter, mortality, sexually transmitted infection, HIV, and tuberculosis (TB) data from the NYC Departments of Health and Mental Hygiene, Correction, and Homeless Services. Compared with nonincarcerated people and those living in the lowest income NYC neighborhoods, those ever incarcerated had higher HIV prevalence and HIV case rates. Ever-incarcerated females also had higher rates of gonorrhea and syphilis than nonincarcerated females. Ever-incarcerated people who used the single adult homeless shelter system had higher HIV, gonorrhea, and TB case rates and all-cause mortality rates than ever-incarcerated people without shelter use, when adjusting for other variables. People ever incarcerated in NYC jails are at risk for conditions of public health importance. Sex-specific jail- and community-based interventions are needed.

- Abstract
Common surgical treatment of first tarsal-metatarsal arthritis is by first metatarsocuneiform joint arthrodesis. While crossed-screw and locking plate fixation are the most widely used methods, a novel construct was designed to alleviate soft tissue irritation while still providing stable fixation. Using anatomic first metatarsal and medial cuneiform composites, we compared 3 arthrodesis implants (crossed-screw, dorsal locking plate, and IO Fix) under 2 cyclic bending loading scenarios (cantilever and 4-point bending). Additionally, the optimal orientation (plantar-dorsal or dorsal-plantar) of the IO Fix construct was determined. Failure load, diastasis, joint space angle, and axial and angular stiffness were determined. Both crossed-screw fixation and the IO Fix constructs experienced significantly higher failure loads than the dorsal locking plate during both loading scenarios. Additionally, they had lower plantar diastasis and joint space angle at failure than the plate. Moreover, the plantar-dorsal IO Fix construct was significantly stiffer than the crossed-screw during cantilever bending. Finally, the plantar-dorsal orientation of the IO Fix device had higher failure load and lower diastasis and angle at failure than in the dorsal-plantar orientation. The results suggest that the IO Fix system can reduce motion at the interfragmentary site and ensure compression for healing comparable to that of the crossed-screw fixation., Levels of Evidence: Level V: Bench testing.

- Abstract
We describe a low-cost (instrument cost) technique for joint distraction using 2 Kirschner wires and a toothed lamina spreader in lieu of a Hintermann distractor. The described technique allows for temporary intra-articular distraction and visualization and preservation of the articular surface with extra-articular instrumentation. The technique can also allow for closed reduction and percutaneous treatment in cases of soft tissue compromise. Additionally, the technique uses common orthopedic surgical instruments, leading to a minimal learning curve for novice surgeons. We have found this distraction technique to be most effective for intra-articular preparation of hindfoot and midfoot arthrodeses and for navicular fracture reduction., (Copyright © 2016 American College of Foot and Ankle Surgeons.

- Abstract
Background: The goal of this study was to evaluate the biomechanical performance of three distal fibula fracture fixation implants in a matched pair cadaveric fibula model: (1) a 5-hole compression plate with lag screw, (2) a 5-hole locking plate with lag screw, and (3) the 6-hole tabbed-plate with locking screws., Methods: Three-dimensional motions between the proximal and distal fibular segments were measured under cyclic valgus bending, cyclic compressive axial loading, and cyclic torsional external-rotation loading. During loading, strains were measured on the surfaces of each fibula near the simulated fracture site, and on the plate, to assess load transfer. Bone quality was quantified globally for each donor using bone mineral density (BMD) measured using Dual X-ray absorptiometry (DEXA) and locally at the fracture site using bone mineral content (BMC) measured using peripheral quantitative computed tomography (pQCT)., Results: Mean failure loads were below 0.2Nm of valgus bending and below 4Nm of external-rotational torque. Mean failure angulation was below 1degree for valgus bending, and failure rotation was below 7degrees for external-rotation. In the compression plate group, significant correlations were observed between bone quality (global BMD and local BMC) and strain in every one of the five locations (Pearson correlation coefficients >0.95, p<0.05). In contrast, in the locking and tabbed-plate groups, BMD and BMC correlated with far fewer strain locations., Conclusions: Overall, the tabbed-plate had similar construct stability and strength to the compression and locking plates. However, the distribution of load with the locking and tabbed-plates was not as heavily dependent on bone quality., (Copyright © 2016 European Foot and Ankle Society. Published by Elsevier Ltd.

- Abstract
Hallux valgus is the most common disorder of the hallux and often results in pain, functional disability, and impaired gait patterns. The goals of surgical management are to correct the deformity while improving patients' pain and function. Traditional treatment of moderate to severe hallux valgus deformities consist of proximal osteotomy and/or arthrodesis given their powerful corrective ability. Despite their corrective power, proximal osteotomies are more technically demanding, have a higher rate of complications, and require a more restricted post-operative recovery. We present an alternative technique for the treatment of moderate to severe hallux valgus. With this operation, a single distal medial incision is utilized to create a chevron osteotomy and lateral release. This procedure can achieve and maintain the desired correction and outcome without the need for a protracted recovery period., Level of Evidence: Level V, expert opinion., (© The Author(s) 2016.)

- Abstract
Background: The aim of this study was to determine the outcome of delayed presentation (at least 6 weeks from the time of injury) of low-energy Lisfranc injuries limited to the first and second tarsometatarsal joints treated with open reduction internal fixation., Methods: 8 patients with an average age at surgery of 39.8 years were retrospectively reviewed with a mean time to surgery from injury of 15.1 (range of 6.3 to 31.1) weeks. We used radiographic measurements, physical examination, SF-12 scores, Foot and Ankle Ability Measure (FAAM) scores, VAS scores and return to work or sports as outcome measures. Patients were treated with an open reduction and internal fixation as opposed to a formal arthrodesis with a variety of internal fixation. All 8 patients were available for follow-up and outcome reporting at an average of 3.1 years (minimum 2.0) postoperatively., Results: The mean VAS improved from 8.5 to 2.8 postoperatively. The mean postoperative physical and mental SF-12 scores were 46.8 and 57.1, respectively. The mean postoperative overall and sports FAAM scores were 75.4 and 65.9, respectively. There were no radiographic signs of a late diastasis at the Lisfranc joint. All patients including 2 workers compensation cases returned to work and all were able to return to their prior sporting activity., Conclusion: A delayed open reduction internal fixation of patients with missed, low-energy Lisfranc injury was performed and resulted in decreased pain. In this series, a fair to good functional outcome was observed, and the ability to return to work or previous sport was possible for all patients studied., Level of Evidence: Level IV, retrospective case series., (© The Author(s) 2016.)

- Abstract
Unlabelled: Talonavicular (TN) arthrodeses for TN arthritis have a high rate of nonunions for an essential hindfoot joint. In this case series, 12 patients underwent an isolated TN arthrodesis using a novel implant (IO FiX) by a single surgeon with a minimum 1-year follow-up (30.1 ± 14.7 months; mean ± SD). All patients (62 ± 12 years) underwent an aggressive rehabilitation protocol given the strength and compression of the implant. There were no nonunions, nor were there any patients lost to follow-up. Time to radiographic union was 9.6 ± 1.4 weeks. The Visual Analog Scale pain level decreased from 7.3 ± 0.9 preoperatively to 2.1 ± 0.7 postoperatively (P < .001). The Short-Form-12 physical component improved from 27.9 ± 4.2 preoperatively to 42.2 ± 3.5 postoperatively (P < 0.001), while the Short-Form-12 mental component did not change from 50.8 ± 6.9 preoperatively to 54.4 ± 3.8 postoperatively (P > .05). Use of the novel fixation device for TN arthrodesis by a single surgeon with an accelerated rehabilitation protocol significantly decreased patients' pain and improved their physical functional outcomes (P < .001). The IO FiX implant can potentially improve TN arthrodesis fusion rates and surgical outcomes., Levels of Evidence: Therapeutic, Level IV: Case series., (© 2015 The Author(s).)

- Abstract
Background: Socioeconomic status (SES) impacts health outcomes. The Youth Risk Behavior Survey (YRBS), like many school-based data sources, lacks individual-level poverty information. We propose using school-level percentages of student eligibility for free/reduced-price meals (%FRPM) as a proxy for individual-level poverty., Methods: Using the New York City (NYC) 2009 YRBS, we created school-level poverty quartiles to append to individual YRBS records by ranking schools by %FRPM. We compared this with 2 other school-level poverty measures using students' home and school neighborhood-level poverty and measured the association of these 3 school-level proxies with individual's household income. Last, we evaluated health outcomes by race/ethnicity and poverty to demonstrate the importance of accounting for poverty., Results: The school-level measure that used %FRPM had the strongest association with household income. When the school-level individual poverty proxy was included in illustrative analyses using YRBS data, patterns by poverty within race/ethnicity emerged that were not seen when looking at race/ethnicity alone., Conclusions: Using a poverty measure to analyze school-based data will provide a better understanding of the impact of SES on health outcomes. Based on our evaluation, when individual-level information is not available, we propose using school-level %FRPM, which are publicly available throughout the United States., (© 2016, American School Health Association.)

- Abstract
Objectives: Both homelessness and incarceration are associated with housing instability, which in turn can disrupt continuity of HIV medical care. Yet, their impacts have not been systematically assessed among people living with HIV/AIDS (PLWHA)., Methods: We studied a retrospective cohort of 1,698 New York City PLWHA with both jail incarceration and homelessness during 2001-05 to evaluate whether frequent transitions between jail incarceration and homelessness were associated with a lower likelihood of continuity of HIV care during a subsequent one-year follow-up period. Using matched jail, single-adult homeless shelter, and HIV registry data, we performed sequence analysis to identify trajectories of these events and assessed their influence on engagement in HIV care and HIV viral suppression via marginal structural modeling., Results: Sequence analysis identified four trajectories; 72% of the cohort had sporadic experiences of both brief incarceration and homelessness, whereas others experienced more consistent incarceration or homelessness during early or late months. Trajectories were not associated with differential engagement in HIV care during follow-up. However, compared with PLWHA experiencing early bouts of homelessness and later minimal incarceration/homelessness events, we observed a lower prevalence of viral suppression among PLWHA with two other trajectories: those with sporadic, brief occurrences of incarceration/homelessness (0.67, 95% CI = 0.50,0.90) and those with extensive incarceration experiences (0.62, 95% CI = 0.43,0.88)., Conclusions: Housing instability due to frequent jail incarceration and homelessness or extensive incarceration may exert negative influences on viral suppression. Policies and services that support housing stability should be strengthened among incarcerated and sheltered PLWHA to reduce risk of adverse health conditions.

- Abstract
Background: Use of the tuberculin skin test (TST) for diagnosis of latent tuberculosis infection (LTBI) among individuals who received the Bacille Calmette-Guérin (BCG) vaccine is complicated by its potential cross-reaction with TST antigens which may cause false-positive results and lead to patient and physician reluctance to initiate LTBI treatment. QuantiFERON®-TB Gold (QFT-G) lacks this cross-reaction. We sought to study the impact of implementing QFT-G testing in 2006 on LTBI treatment initiation and completion at NYC chest clinics., Methods: QFT-G results from 10/2006-12/2008 in NYC Department of Health and Mental Hygiene chest clinics were obtained from the electronic medical record system. The proportions of patients who initiated and completed treatment among patients tested with QFT-G were compared to those tested with TST from 10/2004-9/2006., Results: Among 36,167 patients tested with QFT-G, 2,300 (6%) tested positive, 33,327 (93%) tested negative, and 540 (1%) had an indeterminate result. Among those who had a positive QFT-G test and deemed eligible, 985 (80%) initiated LTBI treatment and 490 (40%) completed treatment. Historically, among patients tested with TST, 7,073 (19%) tested positive (p<0.0001 compared to QFT-G); 3,182 (79%) of those eligible initiated LTBI treatment and 1,210 (30%) completed treatment (p<0.0001 compared to QFT-G)., Conclusions: QFT-G implementation increased the proportion of patients completing LTBI treatment. Additional studies are needed in more settings to determine whether using QFT-G leads to a sustained increase in treatment completion.

- Abstract
Background: Patients with prior positive tuberculin skin test (TST) results may benefit from prophylaxis after repeat exposure to infectious tuberculosis (TB)., Objective: To evaluate factors associated with active TB disease among persons with prior positive TST results named as contacts of persons with infectious TB., Design: Population-based retrospective cohort study., Participants: A total of 2,933 contacts with prior positive TST results recently exposed to infectious TB identified in New York City's TB registry during the period from January 1, 1997 through December 31, 2003., Main Measurements: Contacts developing active TB disease ≤ 4 years after exposure were identified and compared with those who did not, using Poisson regression analysis. Genotyping was performed on selected Mycobacterium tuberculosis-positive isolates., Key Results: Among contacts with prior positive TST results, 39 (1.3 %) developed active TB disease ≤ 4 years after exposure (≤ 2 years: 34). Risk factors for contacts that were independently associated with TB were age < 5 years (adjusted prevalence ratio [aPR] = 19.48; 95 % confidence interval [CI] = 7.15-53.09), household exposure (aPR = 2.60;CI = 1.30-5.21), exposure to infectious patients (i.e., cavities on chest radiograph, acid-fast bacilli on sputum smear; aPR = 1.9 3; CI = 1.01-3.71), and exposure to a U.S.-born index patient (aPR = 4.04; CI = 1.95-8.38). Receipt of more than 1 month of treatment for latent TB infection following the current contact investigation was found to be protective (aPR = 0.27; CI = .08-0.93). Genotype results were concordant with the index patients among 14 of 15 contacts who developed active TB disease and had genotyping results available., Conclusions: Concordant genotype results and a high proportion of contacts developing active TB disease within 2 years of exposure indicate that those with prior positive TST results likely developed active TB disease from recent rather than remote infection. Healthcare providers should consider prophylaxis for contacts with prior TB infection, especially young children and close contacts of TB patients (e.g., those with household exposure).

- Abstract
We studied a cohort of 15,620 adults who had experienced at least 1 jail incarceration and 1 homeless shelter stay in 2001-2003 in New York City to identify trajectories of these events and tested whether a particular trajectory was associated with all-cause, drug-related, or human immunodeficiency virus (HIV)-related mortality risk in 2004-2005. Using matched data on jail time, homeless shelter stays, and vital statistics, we performed sequence analysis and assessed mortality risk using standardized mortality ratios (SMRs) and marginal structural modeling. We identified 6 trajectories. Sixty percent of the cohort members had a temporary pattern, which was characterized by sporadic experiences of brief incarceration and homelessness, whereas the rest had the other 5 patterns, which reflected experiences of increasing, decreasing, or persistent jail or shelter stays. Mortality risk among individuals with a temporary pattern was significantly higher than those of adults who had not been incarcerated or stayed in a homeless shelter during the study period (all-cause SMR: 1.35, 95% confidence interval (CI): 1.14, 1.59; drug-related SMR: 4.60, 95% CI: 3.17, 6.46; HIV-related SMR: 1.54, 95% CI: 1.03, 2.21); all-cause and HIV-related SMRs in other patterns were not statistically significantly different. When we compared all 6 trajectories, the temporary pattern was more strongly associated with higher mortality risk than was the continuously homelessness pattern. Institutional interventions to reduce recurrent cycles of incarceration and homelessness are needed to augment behavioral interventions to reduce mortality risk., (© The Author 2015.
