Mapping schistosoma haematobium for novel interventions against female genital schistosomiasis and associated HIV risk in kwazulu-natal, South Africa
2021
Abstract.Women with female genital schistosomiasis (FGS) have been found to have genital symptoms and a three-fold higher risk of HIV infection. Despite WHO recommendations, regular antischistosomal mass drug administration (MDA) has not yet been implemented in South Africa possibly because of the lack of updated epidemiological data. To provide data for future prevention efforts against FGS and HIV, this study explored Schistosoma haematobium prevalence in girls and young women and the effects of antischistosomal MDA, respectively. Urinary schistosomiasis and genital symptoms were investigated in 70 randomly selected secondary schools in three districts within KwaZulu-Natal and 18 primary …
A study of hurdles in mass treatment of schistosomiasis in KwaZulu-Natal, South Africa
2015
Background: It has been estimated that 700 million people worldwide and 5.2 million people in South Africa are in need of annual treatment for schistosomiasis. In accordance with the current policy the Department of Health (DoH) in KwaZulu-Natal province, South Africa, aimed to reach 75% treatment coverage in a mass treatment campaign (MTC) of schools in a schistosomiasis-endemic area.Methods: A cross-sectional study was designed to explore the implementation, coverage, challenges and limitations of a DoH MTC in a middle-income country. The study was conducted by exploring nurses’ and research team records, school enrolment lists and parental consent forms.Results: Slightly more than 10 000…
N-Acetylcysteine Amide Exerts Possible Neuroprotective Effects in Newborn Pigs after Perinatal Asphyxia
2016
<b><i>Background:</i></b> Perinatal asphyxia and ensuing reoxygenation change the antioxidant capacity of cells and organs. <b><i>Objectives:</i></b> To analyze the neuroprotective effect of the antioxidant N-acetylcysteine amide (NACA) after perinatal hypoxia-reoxygenation with an emphasis on proinflammatory cytokines and the transcription factor NF-&#x03BA;B in the prefrontal cortex of neonatal pigs. <b><i>Methods:</i></b> Twenty-nine newborn pigs, aged 12-36 h, were subjected to global hypoxia and hypercapnia. One sham-operated group (n = 5) and 2 experimental groups (n = 12) were exposed to 8% oxygen, until the …
Predictors of mortality in HIV-infected patients starting antiretroviral therapy in a rural hospital in Tanzania
2008
Background Studies of antiretroviral therapy (ART) programs in Africa have shown high initial mortality. Factors contributing to this high mortality are poorly described. The aim of the present study was to assess mortality and to identify predictors of mortality in HIV-infected patients starting ART in a rural hospital in Tanzania. Methods This was a cohort study of 320 treatment-naïve adults who started ART between October 2003 and November 2006. Reliable CD4 cell counts were not available, thus ART initiation was based on clinical criteria in accordance with WHO and Tanzanian guidelines. Kaplan-Meier models were used to estimate mortality and Cox proportional hazards models to identify p…
Oral health and mortality risk in the institutionalised elderly
2012
Objective: Examining oral health and oral hygiene as predictors of subsequent one-year survival in the institutionalized elderly. Design: It was hypothesized that oral health would be related to mortality in an institutionalized geriatric population. A 12-month prospective study of 292 elderly residing in nine geriatric institutions in Granada, Spain, was thus carried out to evaluate the association between oral health and mortality. Independent samples, T-test, chi-square test and Cox regression analysis were used to analyze the data. Sixty-three participants died during the 12-month follow-up. Results: Mortality was increased in denture users (RR = 2.18, p= 0.007) and in people suffering …
Female genital schistosomiasis--a differential diagnosis to sexually transmitted disease: genital itch and vaginal discharge as indicators of genital…
2008
OBJECTIVE To examine the association between schistosomiasis and reproductive tract symptoms. METHOD A cross-sectional study was conducted in a Schistosoma haematobium-endemic area of rural Zimbabwe. A total of 483 permanently resident adult women of Mupfure Ward aged 20-49 were interviewed and examined clinically, each providing three consecutive urine samples. Logistic regression analysis was used to control for sexually transmitted diseases (STDs). RESULTS Women with genital sandy patches had significantly more genital itch (P = 0.009) and perceived their discharge as abnormal (P = 0.003). Eighty percent of the women who had genital itch, yellow discharge, and childhood or current waterb…
