Blood seminal concentrations measured over 16 weeks.Sixteen men 25 chronic studied. load highest about 17 days after (mean +/-...
Objectives: To estimate the effect of receiving HIV-positive test results on intentions to have future children and contraceptive use assess association between pregnancy incidence among women in Malawi. Methods: Women unknown HIV status completed a questionnaire about then received voluntary counseling testing (VCT). who were not pregnant enrolled followed for 1 year while care access family planning (FP) services. Results: Before their results, 33% reported desire children; this declined...
Objective: Individuals with acute (preseroconversion) HIV infection (AHI) are important in the spread of HIV. The identification AHI requires detection viral proteins or nucleic acids techniques that often unaffordable for routine use. To facilitate efficient use these tests, we sought to develop a risk score algorithm identifying likely cases and targeting tests towards those individuals. Design: A cross-sectional study 1448 adults attending sexually transmitted infections (STI) clinic...
Background. We conducted a prospective study to evaluate methods of detecting clients with sexually transmitted diseases (STDs) who were acutely coinfected human immunodeficiency virus (HIV) in Lilongwe, Malawi. Methods. After informed consent was obtained, all acute STDs offered voluntary HIV counseling and testing by 2 rapid antibody tests. Samples from test-negative or -discordant subjects pooled (50:5:1) tested for RNA. Western blots performed on test-discordant specimens detectable A...
Morbidity and mortality patterns among pregnant women their infants (before antiretroviral therapy was widely available) determines HIV-1 diagnostic, monitoring, care interventions.Data from mothers enrolled in a trial of antibiotics to reduce mother-to-child-transmission at 4 sub-Saharan African sites were analyzed.

Incidences STIs determined by study arm, HRs versus placebo gel or no control groups computed...
Global policy recommendations to scale up of male circumcision (MC) for HIV prevention tend frame the procedure as a simple and efficacious public health intervention. However, there has been variable uptake MC in countries with significant epidemics. Kenya, example, embraced dubbed 'leader' by global community, while Malawi branded 'laggard' its slow adoption national programme, strong political discourse resistance forming around MC. Regardless any epidemiological or technical evidence,...
Despite progress in improving antiretroviral therapy (ART) for people with HIV Malawi, the burden of infections and treatment outcomes among key populations is suboptimal. Client-centered differentiated service delivery approaches may facilitate addressing prevention needs Malawi.De-identified program data routinely collected as part LINKAGES project-Malawi were assembled from October 2017 to September 2019. case finding was compared across different testing modalities each population....
<b>Background:</b> Understanding HIV risk perception is important for designing appropriate strategies HIV/AIDS prevention, because these interventions often rely on behaviour modification. A key component of the individual's own assessment status, and extent to which this correct. However, issue has received limited attention. <b>Objectives:</b> To examine validity self-reported likelihood current infection among general population in rural Malawi. <b>Methods:</b> As part a panel household...
Assessing safety outcomes is critical to inform optimal scale-up of voluntary medical male circumcision (VMMC) programs. Clinical trials demonstrated adverse event (AE) rates from 1.5 8 %, but we have limited data on AEs VMMC programs.A group problem-solving, quality improvement (QI) project involving retrospective chart audits, case-conference AE classification, and provider training was conducted at a clinic in Malawi. For each identified potential AE, the timing, assessment, treatment,...
The objective of this study was to determine the incidence HIV-1.The goal inform HIV prevention and vaccine trials by conducting a multisite in Malawi Zimbabwe.Women reproductive age were enrolled prospective study. They received 5 intensive counseling condom promotion sessions over 2 months. Subsequently, HIV-negative women completed quarterly follow-up visits. rates predictors acquisition assessed.A total 2016 phase Of these, 1679 tested for during follow up 113 seroconverted, resulting an...
Concurrent sexual partnerships are believed to play an important role in HIV transmission sub-Saharan Africa, but the contributions of concurrency and sexually transmitted infection (STI) spread depend on details infectious periods relationship patterns. To contribute understanding partnership patterns this region, we estimated lengths, temporal gaps between partners, overlap across partners at STI clinic Lilongwe, Malawi.Participants underwent physical examinations tests, responded...
Background. Combination antiretroviral therapy (cART) reduces genital tract human immunodeficiency virus type 1 (HIV-1) load and the risk of sexual transmission, but little is known about efficacy cART for decreasing viral (GTVL) differences in sex or HIV-1 subtype.
Variations in estimates of prevalence trichomoniasis men may reflect true differences the burden disease but are also affected by performance diagnostic methods and type specimen tested. In this study, were evaluated at baseline follow-up, to evaluate syndromic management urethritis effects human immunodeficiency virus trichomoniasis, Lilongwe, Malawi. First-void urine specimens urethral swabs obtained enrollment, for Trichomonas vaginalis culture; semen follow-up. The sensitivities testing...
