The SEARCH study provided community-based HIV and multidisease testing and antiretroviral therapy (ART) to 32 communities in East Africa and reported no statistically significant difference in 3-year HIV incidence. We used mathematical modeling to estimate the effect of control arm viral suppression and community mixing on SEARCH trial outcomes.

Uganda and Kenya.

Using the individual-based HIV modeling software EMOD-HIV, we configured a new model of SEARCH communities. The model was parameterized using demographic, HIV prevalence, male circumcision, and viral suppression data and calibrated to HIV prevalence, ART coverage, and population size. Using assumptions about ART scale-up in the control arm, degree of community mixing, and effect of baseline testing, we estimated comparative HIV incidence under multiple scenarios.

Before the trial results, we predicted that SEARCH would report a 4%-40% reduction between arms, depending on control arm ART linkage rates and community mixing. With universal baseline testing followed by rapidly expanded ART eligibility and uptake, modeled effect sizes were smaller than the study was powered to detect. Using interim viral suppression data, we estimated 3-year cumulative incidence would have been reduced by up to 27% in the control arm and 43% in the intervention arm compared with a counterfactual without universal baseline testing.

Our model suggests that the active control arm substantially reduced expected effect size and power of the SEARCH study. ITF2357 However, compared with a counterfactual "true control" without increased ART linkage because of baseline testing, SEARCH reduced HIV incidence by up to 43%.

PrEPX was an Australian HIV pre-exposure prophylaxis (PrEP) study conducted between 2016 and 2018. This analysis aimed to estimate hepatitis C (HCV) incidence and explore likely modes of transmission.

Cohort study of PrEP users in Victoria, Australia.

HCV tests were conducted at enrollment and every 12 months thereafter. HCV incident cases were identified from laboratory data. Likely modes of transmission were inferred from computer-assisted self-interviews, medical records, and interviews.

Among 3202 PrEPX participants tested for HCV at baseline, HCV RNA-positive prevalence was 0.22% (95% confidence interval 0.09 to 0.45). Among participants testing HCV antibody-negative or RNA-negative at baseline, 2058 had at least one follow-up HCV test. Eight incident HCV cases were identified during 2111 person-years of follow-up (incidence 0.38/100 person-years); all were primary infections in men who had sex with men. Clinical, laboratory, and computer-assisted self-interviews data were available for all, and some PrEP-using men who have sex with men.

The World Health Organization recommends differentiated service delivery (DSD) to support resource-limited health systems in providing patient-centered HIV care. DSD offers alternative care models to clinic-based care for people living with HIV who are stable on antiretroviral therapy (ART). Despite good patient-related outcomes, there is limited evidence of their sustainability. Our review evaluated the reporting of sustainability indicators of DSD interventions conducted in sub-Saharan Africa (SSA).

We searched PubMed and EMBASE for studies conducted between 2000 and 2019 assessing DSD interventions targeting HIV-positive individuals who are established in ART in sub-Saharan Africa. We evaluated them through a comprehensive sustainability framework of constructs categorized into 6 domains (intervention design, process, external environment, resources, organizational setting, and people involvement). We scored each construct 1, 2, or 3 for no, partial, or sufficient level of evidence, respectively. Intercould guide informed decisions on which DSD intervention is likely to be sustainable per setting and highlight areas that could motivate further research.Basal cell carcinoma (BCC) is the most frequent skin cancer but less then 1% of the cases develop in the vulva. Histoprognostic features of vulvar BCCs are not recognized and, consequently, the treatment of the disease is not well codified. To overcome this lack of knowledge, we have performed a retrospective analysis of vulvar BBCs to assess the value of various histological features regarding the disease outcome. In all, 19 patients surgically treated for a vulvar BCC in the Centre Hospitalier Intercommunal de Créteil from March 1, 2000 to September 26, 2019 were retrieved. Clinical and histologic features were reviewed in all cases and analyzed in comparison with disease recurrence and patient's survival. Patients' median age was 74 (range 54-99) yr. Tumor location on the labium majus was the most frequent (68%). None presented a medical condition related to BCC. All the patients were treated by surgery alone, except one who benefited from additional radiotherapy. We found a significant association between tumor size and recurrences (P=0.031). Other features associated with disease outcome were tumor thickness, treatment type, and surgical margins. Recurrence was observed for tumors larger than 20 mm with a surgical margin of less than 3 mm. A combination of tumor size, thickness, and surgical margin are histoprognostic factors more significant than tumor subtype.We report 10 cases of a previously undescribed lesion within ovarian teratomas which we designate bronchus-like structures. The lesions occurred in patients aged 16 to 56 yr (mean 36) and involved the left ovary (n=5) or right ovary (n=5). Nine cases were mature teratomas (dermoid cysts/mature cystic teratomas or mature solid teratomas), 1 with somatic malignant transformation, and 1 was an immature teratoma. The bronchus-like structures ranged in size from 2.5 to 10 mm and were unifocal (7 cases) or multifocal (3 cases). The morphology was relatively constant in all cases and characterised by a well-formed bronchus surrounded by glandular structures, some of which were dilated, separated by stroma containing a variable amount of smooth muscle. In all but 1 case, a proportion of the glands contained abundant foamy cytoplasm. There was little or no nuclear atypia or mitotic activity. At low-power, the glands often had a somewhat "infiltrative" appearance and one case was originally diagnosed as a "pulmonary-type" adenocarcinoma arising in a dermoid cyst.
