The causes, treatment, and outcome of acute heart failure in 1006 Africans From 9 countries

Background: Acute heart failure (AHF) in sub-Saharan Africa has not been well characterized. Therefore,wesought to describe the characteristics, treatment, and outcomes of patients admitted with AHF in sub-Saharan Africa. Methods: The Sub-Saharan Africa Survey of Heart Failure (THESUS–HF) was a prospective, multicenter, observational survey of patients with AHF admitted to 12 university hospitals in 9 countries. Among patients presenting with AHF, we determined the causes, treatment, and outcomes during 6 months of follow-up. Results: From July 1, 2007, to June 30, 2010, we enrolled 1006 patients presenting with AHF. Mean (SD) age was 52.3 (18.3) years, 511 (50.8%) were women, and the predominant race was black African (984 of 999 [98.5%]). Mean (SD) left ventricular ejection fraction was 39.5% (16.5%)... Conclusions: In African patients, AHF has a predominantly nonischemic cause, most commonly hypertension. The condition occurs in middle-aged adults, equally in men and women, and is associated with high mortality. The outcome is similar to that observed in non- African AHF registries, suggesting that AHF has a dire prognosis globally, regardless of the cause

Gender differences in clinical characteristics and outcome of acute heart failure in sub-Saharan Africa: results of the THESUS-HF study

Background: The impact of gender on the clinical characteristics, risk factors, co-morbidities, etiology, treatment and outcome of acute heart failure in sub-Saharan Africa has not been described before. The aim of this study was to evaluate the sex diffe rences in acute heart failure in sub-Saharan Africa using the data from The sub-Saharan Africa Survey of Heart Failure (THESUS-HF). Methods and results: 1,006 subjects were recruited into this prospective multicenter, international observational heart failure survey. The mean age of total population was 52.4 years (54.0 years for men and 50.7 years for women). The men were significantly older (p = 0.0045). Men also presented in poorer NYHA functional class (III and IV), p = 0.0364). Cigarette smoking and high blood pressure were significantly commoner in men (17.3 vs. 2.6 % and 60.0 vs. 51.0 % respectively). On the other hand, atrial fibrillation and valvular heart disease were significantly more frequent in women. The mean hemoglobin concentration was lower in women compared to men (11.7 vs. 12.6 g/dl, p ≤ 0.0001), while the blood urea and creatinine levels were higher in men (p \u3c 0.0001). LV systolic dysfunctional was also seen more in men. Men also had higher E/A ratio indicating higher LV filling pressure. Outcomes were similar in both sexes. Conclusions: Although the outcome of patients admitted for AHF in sub-Saharan regions is similar in men and women, some gender differences are apparent suggesting that in men more emphasis should be put on modifiable life risk factors, while in women prevention of rheumatic heart diseases and improved nutrition should be addressed vigorously

Initial evidence of reduction of malaria cases and deaths in Rwanda and Ethiopia due to rapid scale-up of malaria prevention and treatment

<p>Abstract</p> <p>Background</p> <p>An increasing number of malaria-endemic African countries are rapidly scaling up malaria prevention and treatment. To have an initial estimate of the impact of these efforts, time trends in health facility records were evaluated in selected districts in Ethiopia and Rwanda, where long-lasting insecticidal nets (LLIN) and artemisinin-based combination therapy (ACT) had been distributed nationwide by 2007.</p> <p>Methods</p> <p>In Ethiopia, a stratified convenience sample covered four major regions where (moderately) endemic malaria occurs. In Rwanda, two districts were sampled in all five provinces, with one rural health centre and one rural hospital selected in each district. The main impact indicator was percentage change in number of in-patient malaria cases and deaths in children < 5 years old prior to (2001–2005/6) and after (2007) nationwide implementation of LLIN and ACT.</p> <p>Results</p> <p>In-patient malaria cases and deaths in children < 5 years old in Rwanda fell by 55% and 67%, respectively, and in Ethiopia by 73% and 62%. Over this same time period, non-malaria cases and deaths generally remained stable or increased.</p> <p>Conclusion</p> <p>Initial evidence indicated that the combination of mass distribution of LLIN to all children < 5 years or all households and nationwide distribution of ACT in the public sector was associated with substantial declines of in-patient malaria cases and deaths in Rwanda and Ethiopia. Clinic-based data was a useful tool for local monitoring of the impact of malaria programmes.</p

Determinants of agricultural credit market participation and loan repayment performance in Finoteselam town, Northwestern Ethiopa

Ethiopia is one of the world’s poorest nations with a per capita income of about US$157. About 44% of the population live below poverty line. Farmers often lack financial resources to make necessary investments in agriculture. The formal financial services provided by banks are less accessible to poor farmers. Although the informal moneylenders are accessible to the poor farmers, the interest rates charged are very high. As a result, providing rural financial services through microfinance institutions has become part of the poverty reduction strategies of most developing economies. This research was undertaken at Finoteselam Town, Northwestern Ethiopia. It was done with the objectives of estimating the parameters that determine credit market participation and loan repayment performance. Primary data from 200 households were collected through a questionnaire survey during the summer period in 2006. The bivariate probit and logit models were estimated using Stata software. Estimation results of the bivariate probit model indicated that variables such as higher family size, large landholding size, household’s labour endowment, participation in off farm employment activities and incurring unforeseen expenses increased the probability of households to participate in credit markets. On the other hand, variables such as village dummy and borrowing from other sources decreased the probability of households to participate in the credit scheme. Estimation results of the logit model revealed that variables such as higher family size, incurring unforeseen expenses, and taking loans for the purpose of oxen fattening decreased the probability of repayment performances. On the other hand, variables such as participation in off farm employment activities and an increase in loan term increased the probability of loan repayment performances. Microfinance institutions like ACSI should target those poor households that participate in off farm employment activities, and those with better labour endowment. They should also focus on supervision of clients so as to avoid diversion of loans to consumption ends due to unforeseen expenses, or higher dependency burden. Family planning, creating enabling conditions for insurance markets, and enhancing labour markets are areas of policy concerns

Socioeconomic factors affecting tree species abundance and composition in Gondar, Ethiopia

The study investigated if there is variation in the frequency of tree species maintained at household level, and the socioeconomic factors that can explain its variation. Data were collected from 156 randomly selected households in 2009 in Ambober village of Gondar district, Ethiopia. Farm visits and recording, observation, group discussion and interview were the methods used to collect the data. Data were analyzed using mean, independent samples test, one way analysis of variance, and multiple regression techniques. The results showed that there was significant variation in tree species abundance with fast growing tree species like Ecucalyptus camaldulensis being the most common. The ordinary least square estimation results indicated that family size, income, and household’s head age contributed positively towards household level tree species abundance. While farm size, tropical livestock unit, walking distance affected the variation in tree species abundance negatively, sex of household head, location dummy, land tenure and years of land ownership turned out to be insignificant. On the other hand, tropical livestock unit, family size, income, household’s head age, tenure insecurity, and walking distance positively affected household level tree species composition. Introduction of multi-purpose tree species that have animal feed values and that can address the fuel wood demand of farm households is believed to enhance household level tree species abundance

Incidence and Predictors of Pregnancy among Women on ART in Debre Markos Referral Hospital, Northwest Ethiopia: A Five-Year Retrospective Cohort Study

Globally, death of women due to HIV/AIDS related causes during pregnancy or within 42 days after pregnancy was estimated to be 37,000. In Ethiopia, 42,900 pregnant women living with HIV gave birth in the year 2011. This study was aimed to assess incidence and predictors of pregnancy among women on ART in Debre Markos Referral Hospital, Northwest Ethiopia. A retrospective cohort study was conducted using data recorded from September 2011 to August 2015. Data was extracted from February to March, 2016, from 1,239 records and analyzed using SPSS version 16. A Kaplan-Meier survival analysis was used to estimate the probabilities of being pregnant. The Cox proportional hazards model was done and results were expressed using hazard ratios with 95% CI. A total of 1,239 women on ART were included in the study. The incidence of pregnancy was 49.2 per 1,000 person-years. Living in rural, being married, being widowed, being unemployed, and having <2 children at enrollment were found to be positively associated with being pregnant. The incidence of pregnancy among women on ART was found to be considerable. Provision of family planning and other reproductive health interventions have to be coupled with the ART service to address the problem

Time series analysis of trends in malaria cases and deaths at hospitals and the effect of antimalarial interventions, 2001-2011, Ethiopia.

The Government of Ethiopia and its partners have deployed artemisinin-based combination therapies (ACT) since 2004 and long-lasting insecticidal nets (LLINs) since 2005. Malaria interventions and trends in malaria cases and deaths were assessed at hospitals in malaria transmission areas during 2001-2011.Regional LLINs distribution records were used to estimate the proportion of the population-at-risk protected by LLINs. Hospital records were reviewed to estimate ACT availability. Time-series analysis was applied to data from 41 hospitals in malaria risk areas to assess trends of malaria cases and deaths during pre-intervention (2001-2005) and post-interventions (2006-2011) periods.The proportion of the population-at-risk potentially protected by LLINs increased to 51% in 2011. The proportion of facilities with ACTs in stock exceeded 87% during 2006-2011. Among all ages, confirmed malaria cases in 2011 declined by 66% (95% confidence interval [CI], 44-79%) and SPR by 37% (CI, 20%-51%) compared to the level predicted by pre-intervention trends. In children under 5 years of age, malaria admissions and deaths fell by 81% (CI, 47%-94%) and 73% (CI, 48%-86%) respectively. Optimal breakpoint of the trendlines occurred between January and June 2006, consistent with the timing of malaria interventions. Over the same period, non-malaria cases and deaths either increased or remained unchanged, the number of malaria diagnostic tests performed reflected the decline in malaria cases, and rainfall remained at levels supportive of malaria transmission.Malaria cases and deaths in Ethiopian hospitals decreased substantially during 2006-2011 in conjunction with scale-up of malaria interventions. The decrease could not be accounted for by changes in hospital visits, malaria diagnostic testing or rainfall. However, given the history of variable malaria transmission in Ethiopia, more data would be required to exclude the possibility that the decrease is due to other factors

Symptoms and signs of heart failure at admission and discharge and outcomes in the Sub-Saharan Acute Heart Failure (THESUS-HF) Registry

Background: Symptoms and signs of heart failure (HF) are the most common reasons for admission to hospital for acute HF (AHF) and are used routinely throughout admission to assess the severity of disease and response to therapy. Methods and Results: The data here collected in The Sub-Saharan Africa Survey on Heart Failure (THESUSHF) study, a prospective, multicenter, observational survey of AHF from 9 countries in sub-Saharan Africa. A total of 1006 patients, ≥12 years of age, hospitalized for AHF were recruited. Symptoms and signs of HF and changes in dyspnea and well-being, relative to admission, were assessed at entry and on days 1, 2, and 7 (or on discharge if earlier) and included oxygen saturation, degree of edema and rales, body weight, and level of orthopnea. The patient determined dyspnea and general well-being, whereas the physician determined symptoms and signs of HF, as well as improvements in vital sign measurement, throughout the admission. After multivariable adjustment, baseline rales and changes to day 7 or discharge in general wellbeing predicted death or HF hospitalization through day 60, and baseline orthopnea, edema, rales, oxygen saturation, and changes to day 7 or on discharge in respiratory rate and general well-being were predictive of death through day 180. Conclusions: In AHF patients in sub-Saharan Africa, symptoms and signs of HF improve throughout admission, and simple assessments, including edema, rales, oxygen saturation, respiratory rate, and asking the patient about general well-being, are valuable tools in patients’ clinical assessment
