Disease-specific mortality burdens in a rural Gambian population using verbal autopsy, 1998-2007.

OBJECTIVE: To estimate and evaluate the cause-of-death structure and disease-specific mortality rates in a rural area of The Gambia as determined using the InterVA-4 model. DESIGN: Deaths and person-years of observation were determined by age group for the population of the Farafenni Health and Demographic Surveillance area from January 1998 to December 2007. Causes of death were determined by verbal autopsy (VA) using the InterVA-4 model and ICD-10 disease classification. Assigned causes of death were classified into six broad groups: infectious and parasitic diseases; cancers; other non-communicable diseases; neonatal; maternal; and external causes. Poisson regression was used to estimate age and disease-specific mortality rates, and likelihood ratio tests were used to determine statistical significance. RESULTS: A total of 3,203 deaths were recorded and VA administered for 2,275 (71%). All-age mortality declined from 15 per 1,000 person-years in 1998-2001 to 8 per 1,000 person-years in 2005-2007. Children aged 1-4 years registered the most marked (74%) decline from 27 to 7 per 1,000 person-years. Communicable diseases accounted for half (49.9%) of the deaths in all age groups, dominated by acute respiratory infections (ARI) (13.7%), malaria (12.9%) and pulmonary tuberculosis (10.2%). The leading causes of death among infants were ARI (5.59 per 1,000 person-years [95% CI: 4.38-7.15]) and malaria (4.11 per 1,000 person-years [95% CI: 3.09-5.47]). Mortality rates in children aged 1-4 years were 3.06 per 1,000 person-years (95% CI: 2.58-3.63) for malaria, and 1.05 per 1,000 person-years (95% CI: 0.79-1.41) for ARI. The HIV-related mortality rate in this age group was 1.17 per 1,000 person-years (95% CI: 0.89-1.54). Pulmonary tuberculosis and communicable diseases other than malaria, HIV/AIDS and ARI were the main killers of adults aged 15 years and over. Stroke-related mortality increased to become the leading cause of death among the elderly aged 60 years or more in 2005-2007. CONCLUSIONS: Mortality in the Farafenni HDSS area was dominated by communicable diseases. Malaria and ARI were the leading causes of death in the general population. In addition to these, diarrhoeal disease was a particularly important cause of death among children under 5 years of age, as was pulmonary tuberculosis among adults aged 15 years and above

Strengthening the emergency healthcare system for mothers and children in The Gambia

A system to improve the management of emergencies during pregnancy, childbirth, infancy and childhood in a region of The Gambia (Brikama) with a population of approximately 250,000 has been developed

Serogroup W135 meningococcal disease, The Gambia, 2012.

In 2012, an outbreak of Neisseria meningitidis serogroup W135 occurred in The Gambia. The attack rate was highest among young children. The associated risk factors were male sex, contact with meningitis patients, and difficult breathing. Enhanced surveillance facilitates early epidemic detection, and multiserogroup conjugate vaccine could reduce meningococcal epidemics in The Gambia

Socio-cultural factors influencing the decision of women to seek care during pregnancy and delivery: A qualitative study in South Tongu District, Ghana

Many low-income countries still encounter high mortality rates. The use of maternal health care services is known to be a key intervention in reducing maternal death. Despite investment in the healthcare sector, in 2015 Ghana did not meet the Millennium Development Goal 5 of reducing maternal mortality (MM). The Volta Region registered the highest rate of MM, the lowest percentage of antenatal care (ANC) coverage and the lowest percentage of skilled delivery. This is a qualitative study that used focus group discussions and key-informant interviews to explore the views on pregnancy among rural communities in the Volta Region, identify the barriers in accessing ANC and skilled attendance birth and collect views on how to improve the access to maternal care services. Overall, the study argues that members of the community of the rural villages acknowledge the benefits of ANC and skilled delivery, and the potential risk related to home delivery. However, pregnant women in the Volta Region still encounter different kinds of obstacles that prevent them from seeking maternal health care. These obstacles are driven by social and economic constraints, and by the fact that women may still lack voice in the decision-making process, and by low males’ participation

Ophthalmia Secondary to Cobra Venom Spitting in the Volta Region, Ghana: A Case Report

Purpose: To report the first case of ophthalmia due to contact with cobra venom in the Volta Region, Ghana. Methods: An ointment containing vitamin A was applied to treat the patient’s unilateral defects in the corneal epithelium and the consequent diminished visual acuity. Results: Healing of the corneal epithelium and improvement of visual acuity were observed after only 1 day. Conclusions: This case suggests that consequences of cases of cobra venom spitting in the eyes can be minimal if immediate treatment is provided

Could Mucuna pruriens be the answer to Parkinson's disease management in sub-Saharan Africa and other low-income countries worldwide?

Parkinson's disease (PD) is a progressive, disabling, neurodegenerative disease that requires long term care and pharmaceutical treatment. Levodopa remains the gold standard treatment for PD globally, although it is largely unavailable and unaffordable for the majority of patients in many sub-Saharan African and other low-income countries (LICs). We suggest the potential for Mucuna pruriens (MP), a leguminous plant, to replace or supplement levodopa-based medicines in countries where levodopa is unaffordable and inaccessible due to its low costs of preparation and high natural availability. MP has been shown to induce a great improvement of motor symptoms with few adverse events in recent studies. However, caution is important until more robust data on the long-term safety of MP are available. We believe that MP could potentially be part of the answer to affordable, symptomatic treatment of PD in LICs worldwide

Trichomonas vaginalis infection and the diagnostic significance of detection tests among Ghanaian outpatients

Abstract Background There is little data on Trichomonas vaginalis infection in Ghana. This study evaluated the prevalence of trichomoniasis using different diagnostic methods and determined the risk factors for infection in patients. Methods A structured questionnaire was administered. Vaginal swabs, urethral swabs and urine specimens were obtained from consenting patients; and the samples processed following standard protocols. The presence of T. vaginalis was determined using wet mount microscopy and polymerase chain reaction (PCR) as gold standard. We also assessed the diagnostic performance the JD’s Trichomonas V® rapid antigen test to inform clinical practice. Results The PCR assay detected T. vaginalis positivity in 64 of 150 patients (42.6, 95%CI:35.0, 50.6) including all positive samples of wet mount microscopy and JD’s Trichomonas V® test. Wet mount microscopy showed low sensitivity (31.6%), high specificity (100%), moderate positive predictive value (75.0%), moderate positive likelihood ratio (3.0), and weak agreement (Cohen’s kappa, 0.283) with PCR assay. The JD’s Trichomonas V® test displayed lower sensitivity (25.0%), specificity (83.3%), and weaker measure of agreement (Cohen’s kappa, 0.233) with PCR. In multivariate analysis, the strongest independent predictor for T. vaginalis was female gender [adjusted odds ratio (AOR), 24.89; 95% confidence interval (CI): 10.58, 51.21; P-value< 0.001]. Knowledge of STI showed a protective effect against infection with the parasite (AOR, 0.13; 95%CI: 0.07, 0.29; P-value< 0.017). Conclusion The sensitivity of wet mount microscopy was low for T. vaginalis screening in our region. The JD’s Trichomonas V® test should not be considered as an alternative test. We recommend mandatory PCR assay for confirmation of negative wet mount results

Trichomoniasis and associated co-infections of the genital tract among pregnant women presenting at two hospitals in Ghana

Abstract Background Trichomonas vaginalis (TV) infection is the most prevalent non-viral sexually transmitted pathogen worldwide. Among pregnant women, the infection may cause adverse birth outcomes such as premature rupture of membranes and premature labour. In view of the paucity of information relating to TV among Ghanaian pregnant women, this study investigated its prevalence and associated co-infections among pregnant women. Methods High vaginal swabs were obtained from 99 pregnant women using sterile cotton swab sticks. Wet preparation, Grams staining, culturing, coagulase and sensitivity testing were carried out to determine the presence of TV and associated microorganisms. Results The prevalence of TV among the pregnant women was found to be 20.2% (n = 20). Concurring with Trichomoniasis, 75% (n = 15) of participants had other infections such as Candida with prevalence of 53% (n = 8), Proteus infection - 20% (n = 3), Streptococcus infection - 13% (n = 2) and other GNRs and Gonococci having 7% each (n = 1). Moreover, there was 86.9% (n = 86) prevalence of Staphylococcus spp. among study participants. There was statistically significant correlation between TV and Gonococci infection at a correlation co-efficient of 0.107 (P < 0.05) as well as significant correlation between TV and Proteus spp. at a correlation co-efficient of 0.189 (P < 0.05). TV infection was high (60%) among the most sexually active age group (19 to 29 yrs). Conclusion There was 20.2% prevalence of TV among the pregnant women presenting at the hospitals, with Gonococci and Proteus infections being statistically significant associated infections

Health & Demographic Surveillance System Profile: Farafenni Health and Demographic Surveillance System in The Gambia.

The Farafenni Health and Demographic Surveillance System (Farafenni HDSS) is located 170 km from the coast in a rural area of The Gambia, north of the River Gambia. It was set up in 1981 by the UK Medical Research Council Laboratories to generate demographic and health information required for the evaluation of a village-based, primary health care programme in 40 villages. Regular updates of demographic events and residency status have subsequently been conducted every 4 months. The surveillance area was extended in 2002 to include Farafenni Town and surrounding villages to support randomized, controlled trials. With over three decades of prospective surveillance, and through specific scientific investigations, the platform (population ≈ 50,000) has generated data on: morbidity and mortality due to malaria in children and during pregnancy; non-communicable disease among adults; reproductive health; and levels and trends in childhood and maternal mortality. Other information routinely collected includes causes of death through verbal autopsy, and household socioeconomic indicators. The current portfolio of the platform includes tracking Millennium Development Goal 4 (MDG4) attainments in rural Gambia and cause-of-death determination
