Congenital syphilis is the oldest recognized congenital infection, and continues to account for extensive global perinatal morbidity mortality today. Serious adverse pregnancy outcomes caused by maternal infection are prevented with screening early in prompt treatment of women testing positive. Intramuscular penicillin, an inexpensive antibiotic on essential medicine list nations all over world, effectively cures prevents syphilis. In fact, at a cost $11-15 per disability adjusted life year...
With use of polymerase chain reaction (PCR) and a centrifugation-enhanced viral culture method, we characterized the viruses causing acute respiratory infection in adults during an influenza season.During January-March 2002, nasopharyngeal wash specimens from previously healthy presenting with symptoms were evaluated for pathogens PCR.The diagnoses 266 cases included unspecified upper (in 142 [54%] cases), bronchitis (42 [16%]), sinusitis (23 [9%]), pharyngitis (22 [8%]), pneumonia (17...
Introduction: Male partner HIV testing has been recognized as an important component of prevention mother-to-child transmission. Scheduled home-based couple may be effective strategy to reach men. Methods: Women attending their first antenatal visit at Kisumu County Hospital in Kenya were randomized education and within 2 weeks enrollment (HOPE) or written invitations for male partners attend clinic (INVITE). maternal child health outcomes compared 6 months postpartum. Results: Of 1101 women...
Summary paragraph To meet the ambitious objectives of biodiversity and climate conventions, countries international community require clarity on how these can be operationalized spatially, multiple targets pursued concurrently 1 . support governments political spatial guidance is needed to identify which areas should managed for conservation generate greatest synergies between nature’s contribution people (NCP). Here we present results from a joint optimization that maximizes improvements in...
To control the COVID-19 pandemic high vaccine acceptability and uptake will be needed. Teachers represent a priority population to minimize social disruption ensure continuity in education, which is vital for well-being healthy development of youth during pandemic. The objective this analysis was measure public school teachers' intentions receive British Columbia (BC), Canada. A population-wide cross-sectional online survey from August November 2020 asked all BC teachers with an available...
Calls for supporting sustainability through more and better research rest on an incomplete understanding of scientific evidence use. We argue that a variety barriers to transformative impact arises from diverse actor motivations within different stages abductively specify this in policy practice arenas three (truth-seeking, sense-making, utility-maximizing) five (evidence production, uptake, influence decisions, effects outcomes, feedback outcome evaluations). Our interdisciplinary synthesis...
Abstract Although trees have high economic, cultural and ecological value, increasing numbers of species are potentially at risk extinction because forest loss degradation as a result human activities, including overharvesting, fire grazing. Emerging threats include climate change its interaction with the spread pests diseases. The impact such on conservation status is poorly understood. Here we highlight need to conduct comprehensive assessment world's tree species, building previous...
Current farm systems rely on the use of Plant Protection Products (PPP) to secure high productivity and control threats quality crops. However, PPP may have considerable impacts human health environment. A study protocol is presented aiming determine occurrence levels residues in plants (crops), animals (livestock), humans other non-target species (ecosystem representatives) for exposure modelling impact assessment. To achieve this, we designed a cross-sectional compare conventional organic...
The World Health Organization's (WHO) Strategic Framework for the Elimination of New HIV Infections among Children in Africa by 2015 identifies important synergies elimination mother-to-child transmission and syphilis terms prevention interventions, implementation logistics service delivery, monitoring evaluation systems, need sustained political commitment. WHO advocates use an integrated, rights-based dual approach with partnerships collaboration to make best available resources. Through a...
Women in sub-Saharan Africa face a 2-fold higher risk of HIV acquisition during pregnancy and postpartum the majority do not know status their male partner. Home-based couple testing for pregnant women can reduce transmission to infants while increasing antiretroviral therapy (ART) coverage men. However, cost-effectiveness this program has been evaluated.We modeled health economic impact implementing home-based partner education (HOPE) intervention partners region Western Kenya (formally...
ObjectivesTo determine prevalence, risk factors, and simple identification algorithms for HIV, hepatitis B, C co-infection; factors that may predispose anti-tuberculosis therapy-induced hepatotoxicity.MethodsWe recruited 300 individuals at in-patient tuberculosis hospitals in three cities Georgia, administered a behavioral questionnaire, tested antibody to (HCV), B core antigen (anti-HBc), the surface (HBsAg).ResultsOf tested, 0.7% were HIV positive, 4.3% HBsAg 8.7% anti-HBc 12.0% HCV...
Background Few men are tested for syphilis or human immunodeficiency virus (HIV) during their partner’s pregnancy, a high-risk period HIV and transmission. Offering home-based rapid testing of to couples pregnancy can support prevention efforts reduce transmission sexually transmitted diseases adverse outcomes. Methods We assessed men’s uptake paired (separate tests, single blood draw) point-of-care tests within randomized controlled trial pregnant women who received clinic home partner...
Objectives Teachers are an important occupational group to consider when addressing vaccine confidence and uptake for school-aged children due their proximate role within school-based immunization programs. The objectives of this study were characterize identify sociodemographic factors associated with describe teachers’ knowledge perceived in the program, aim informing public health policy identifying opportunities supporting teachers Methods A cross-sectional survey elementary secondary...
Home-based human immunodeficiency virus (HIV) testing and education has increased HIV test uptake access to health services among men. We studied how a home-based antenatal intervention influenced male partner utilization of clinic-based sexually transmitted infection (STI) services, linkage care medical circumcision.We conducted secondary analysis within randomized controlled trial pregnant women attending in Kenya. Women their partners received either couple or an invitation letter for...
Globally only 79% of adults living with HIV (human immunodeficiency virus) know their status and men in sub-Saharan Africa are considered a particularly hard-to-reach population for testing. Home-based couple testing during the antenatal period is safe effective method that has been used to test male partners pregnant women. The goal this qualitative study was identify elements made successful describe important characteristics home-based intervention from couples' perspectives.Couples who...
<h3>Introduction</h3> Few men are tested for syphilis or HIV during their partners' pregnancy, a period of high transmission risk and preventable adverse pregnancy outcomes. Offering home-based STI education point-of-care (POC) testing to couples can support programs reduce sexually transmitted infections <h3>Methods</h3> We assessed male partner uptake paired POC tests within randomised controlled trial (RCT) 600 pregnant women partners in Kenya. Married cohabiting were unaccompanied...
Background Of the 12 million global adult syphilis infections occurring globally each year, disproportionately affects women in low-income countries. WHO estimates about 80% of positive pregnancies go untreated, often Latin America and Africa. Economic socio-structural characteristics may explain some vulnerability for infection. We studied association between social health services factors Haiti, a poor country with high burden Methods used data collected clinic-based case-control study...
