Priority Interventions To Reduce Hiv Transmission In Sex Work Settings In Sub-Saharan Africa And Delivery Of These Services, Matthew F. Chersich, Stanley Luchters, Innocent Ntaganira, Antonio Gerbase, Ying-Ru Lo, Fiona Scorgie, Richard Steen

Population Health, East Africa

Introduction: Virtually no African country provides HIV prevention services in sex work settings with an adequate scale and intensity. Uncertainty remains about the optimal set of interventions and mode of delivery.

Methods: We systematically reviewed studies reporting interventions for reducing HIV transmission among female sex workers in sub-Saharan Africa between January 2000 and July 2011. Medline (PubMed) and non-indexed journals were searched for studies with quantitative study outcomes.

Results: We located 26 studies, including seven randomized trials. Evidence supports implementation of the following interventions to reduce unprotected sex among female sex workers: peer-mediated condom promotion, risk-reduction counselling and skills-building for …

Effectiveness Of A Community-Based Positive Prevention Intervention For People Living With Hiv Who Are Not Receiving Antiretroviral Treatment: A Prospective Cohort Study, Avina Sarna, Stanley Luchters, Eustasius Musenge, Jerry Okal, Matthew Chersich, Waimar Tun, Sabine Mall, Nzioki Kingola, Sam Kalibala

Population Health, East Africa

Background: We report effectiveness of an HIV-prevention intervention delivered by community health workers (CHWs) in Mombasa, Kenya, to PLHIV who have not initiated or who have discontinued ART-an often difficult-to-reach population because they fall outside the ambit of health care and prevention services.

Methods: A 2-arm cohort study assessed a structured risk-reduction intervention involving at least 4 one-to-one counseling sessions and personalized support. The control group received standard prevention services. CHWs recruited treatment-naïve people living with HIV (PLHIV) or those who had previously taken antiretroviral drugs. Data were analyzed using a Propensity Score Matched (PSM)-sample to control for baseline differences …

Acute Aortic Valve Rupture From Infective Endocarditis After Transrectal Prostate Biopsy: A Call To Revise The Aha Guidelines For Prevention Of Infective Endocarditis, Julia Ansari, Gurkaran Singh Garcha, Henry Huang, Faisal G. Bakaeen, Salim S. Virani, Hani Jneid

Office of the Provost

We describe the case of a 63-year-old man with a known murmur who presented with a 4-month history of intermittent fever and a progressive reduction in energy level after a transrectal prostate biopsy (TRPB). He subsequently presented with acute heart failure secondary to aortic valve cusp rupture caused by endocarditis and underwent urgent aortic valve surgery. The 2008 American College of Cardiology/American Heart Association Guideline update on infective endocarditis has narrowed the use of antibiotic prophylaxis before most accepted dental procedures and continues to recommend against prophylaxis before genitourinary or gastrointestinal procedures. In contrast, the American Urological Association recommends the …

Sickle Cell Disease In Pregnancy: Trend And Pregnancy Outcomes At A Tertiary Hospital In Tanzania, Projestine S. Muganyizi, Hussein Kidanto

Faculty of Health Sciences, East Africa

SCD in pregnancy is associated with increased adverse fetal and maternal outcomes. In Tanzania where the frequency of sickle cell trait is 13% there has been scanty data on SCD in pregnancy. With progressive improvement in childhood survival the burden of SCD in pregnancy will increase. We analyzed all deliveries at Muhimbili National Hospital (MNH) from 1999 to 2011. Fetal and maternal outcomes of SCD deliveries were compared with non-SCD. Data were analyzed using IBM SPSS statistics version 19. Chi square and Fisher Exact tests were used to compare proportions and the independent t-test for continuous data. To predict risks …

Clinical Application Of Nightingale’S Environmental Theory, Shirin Rahim

School of Nursing & Midwifery

Florence Nightingale (1820-1910) the first nursing theorist and the first one to lay the foundation of modern nursing has based her philosophy on spiritualism. Selanders (2010) quotes (Cook, 1913, Vol. 1, p. 15) in saying, that “She records in her diary an interaction with God at age 16 when He “called her to His service” (p.82). Her devotion towards God and her belief of spirituality was the foundation of almost all that Nightingale did as a nurse and for nursing profession. (Allighood and Tommy 2010). Nightingale has taken the same premise for her environmental theory. In this theory Nightingale (1860) …

Internal Medicine, East Africa

Background:Criminal activity and social problems are recognized as important outcomes of substance use and abuse. Little research has been carried out on substance use among prison inmates in Kenya. General population surveys that have examined drug use usually omit this‘hidden’population which may offer insight into drug related morbidity and invaluable preventive measures. This study is set out to determine the lifetime prevalence and factors associated with substance use, including the most frequently used substances, among inmates at a government prison in Western Kenya.

Methods:Design: A cross-sectional descriptive study, using the WHO model questionnaire and an additional drug use …

Evaluating Audio Computer Assisted Self-Interviews In Urban South African Communities: Evidence For Good Suitability And Reduced Social Desirability Bias Of A Cross-Sectional Survey On Sexual Behaviour, Roxanne Beauclair, Fei Meng, Nele Deprez, Marleen Temmerman, Alex Welte, Wim Delva, Niel Hens

Obstetrics and Gynaecology, East Africa

Background: Efficient HIV prevention requires accurate identification of individuals with risky sexual behaviour. However, self-reported data from sexual behaviour surveys are prone to social desirability bias (SDB). Audio Computer-Assisted Self-Interviewing (ACASI) has been suggested as an alternative to face-to-face interviewing (FTFI), because it may promote interview privacy and reduce SDB. However, little is known about the suitability and accuracy of ACASI in urban communities with high HIV prevalence in South Africa. To test this, we conducted a sexual behaviour survey in Cape Town, South Africa, using ACASI methods.

Methods: Participants (n = 878) answered questions about their sexual relationships on …

Loss Of Dystrophin Staining In Cardiomyocytes: A Novel Method For Detection Early Myocardial Infarction, Satwat Hashmi, Suhail Al-Salam

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most frequent diagnosis made in majority of sudden death cases subjected to clinical and medicolegal autopsies. When sudden death occurs at a very early stage of MI, traditional macroscopic examination, or histological stains cannot easily detect the myocardial changes. For this reason we propose a new method for detecting MI at an early stage. Murine model of MI was used to induce MI through permanent ligation of left anterior descending branch of left coronary artery. Five groups of C57B6/J mice were used for inducing MI, which includes 20 minutes, 30 minutes, one hour, four hours …

Community Health Sciences

Background: In Pakistan, the uptake rate for the intrauterine device (IUD) is very low at 2.5%. The most popular modern contraceptive methods in Pakistan are female sterilization and use of condoms. The Marie Stopes Society established its mobile outreach service delivery program with the aim of increasing use of modern quality contraceptive services, including the long-term reversible IUD, by women living in hard-to-reach areas. The present study attempts to assess IUD discontinuation rates and associated factors, including switching behavior and level of satisfaction with this type of service delivery.
Methods: Using a cross-sectional approach, we contacted 681 women who had …

Paediatrics and Child Health, East Africa

Background: Newborns and young infants suffer high rates of infections in South Asia and sub-Saharan Africa. Timely access to appropriate antibiotic therapy is essential for reducing mortality. In an effort to develop community case management guidelines for young infants, 0–59 days old, with clinically diagnosed severe infections, or with fast breathing, 4 trials of simplified antibiotic therapy delivered in primary care clinics (Pakistan, Democratic Republic of Congo, Kenya and Nigeria) or at home (Bangladesh and Nigeria) are being conducted.
