Estimating the Number of Secondary Ebola Cases Resulting From an Unsafe Burial and Risk Factors for Transmission During the West Africica Ebola Epidemic
No full textSafely burying Ebola infected individuals is acknowledged to be important for controlling Ebola epidemics and was a major component of the 2013-2016 West Africa Ebola response. Yet, in order to understand the impact of safe burial programs it is necessary to elucidate the role of unsafe burials in sustaining chains of Ebola transmission and how the risk posed by activities surrounding unsafe burials, including care provided at home prior to death, vary with human behavior and geography
Are American Surgical Residents Prepared for Humanitarian Deployment?: A Comparative Analysis of Resident and Humanitarian Case Logs
No full textEffective humanitarian surgeons require skills in general surgery, OB/GYN, orthopedics, and urology. With increasing specialization, it is unclear whether US general surgery residents are receiving exposure to these disparate fields. We sought to assess the preparedness of graduating American surgical residents for humanitarian deployment
Does Timing of Antiretroviral Treatment Influence Treatment Outcomes of Visceral Leishmaniasis in Northwest Ethiopia?
No full textVisceral leishmaniasis (VL) patients with HIV co-infection should receive antiretroviral treatment (ART). However, the best timing for initiation of ART is not known. Among such individuals, we assessed the influence of ART timing on VL outcomes
Missed Opportunities for Earlier Diagnosis of rifampicin-resistant Tuberculosis despite access to Xpert(®) MTB/RIF
No full textTo assess the proportion of rifampicin-resistant tuberculosis (RR-TB) patients with potential earlier RR-TB diagnoses in Khayelitsha, South Africa
Management of malaria in children with fever in rural Sierra Leone in relation to the 2014-2015 Ebola outbreak
No full textSetting: Sixty-eight primary health facilities, Koinadugu District, rural Sierra Leone. Objectives: Sierra Leone, a country with one of the highest burdens of malaria, was severely affected by the 2014-2015 Ebola virus disease outbreak. In under-five children, we compared trends in the completeness of malaria reports sent to the district office during the pre-Ebola, Ebola and post-Ebola periods, including the number of children with reported fever, malaria diagnostic testing performed and treatment for malaria initiated with artemisinin-based combination therapy (ACT). Design: A cross-sectional study. Results: Of 1904 expected malaria reports, 1289 (68%) were received. Completeness of reporting was 61% pre-Ebola, increased to 88% during the outbreak and dropped to 44% post-Ebola (P = 0.003). Total malaria testing (n = 105 558) exceeded the number of fever cases (n = 105 320). Pre-Ebola, 75% (n = 43 245) of all reported fever cases received malaria treatment, dropping to 34% (n = 50 453) during the Ebola outbreak. Of 36 804 confirmed malaria cases during Ebola, 17 438 (47%) were treated, significantly fewer than in the pre-Ebola period (96%, P < 0.001). Of the fever cases, 95% in both the pre- and post-Ebola periods received ACT, a rate that increased to 99% during the Ebola outbreak. Conclusion: Pre-existing gaps in malaria reporting worsened after the Ebola outbreak. Reassuringly, malaria testing matched fever cases, although only half of all confirmed cases received treatment during the outbreak, possibly explained by outbreak-related operational difficulties. These findings could be useful to guide health systems strengthening and recovery
Ten Tips to Improve the Visibility and Dissemination of Research for Policy Makers and Practitioners
No full textEl Niño and the Shifting Geography of Cholera in Africa
No full textThe El Niño Southern Oscillation (ENSO) and other climate patterns can have profound impacts on the occurrence of infectious diseases ranging from dengue to cholera. In Africa, El Niño conditions are associated with increased rainfall in East Africa and decreased rainfall in southern Africa, West Africa, and parts of the Sahel. Because of the key role of water supplies in cholera transmission, a relationship between El Niño events and cholera incidence is highly plausible, and previous research has shown a link between ENSO patterns and cholera in Bangladesh. However, there is little systematic evidence for this link in Africa. Using high-resolution mapping techniques, we find that the annual geographic distribution of cholera in Africa from 2000 to 2014 changes dramatically, with the burden shifting to continental East Africa-and away from Madagascar and portions of southern, Central, and West Africa-where almost 50,000 additional cases occur during El Niño years. Cholera incidence during El Niño years was higher in regions of East Africa with increased rainfall, but incidence was also higher in some areas with decreased rainfall, suggesting a complex relationship between rainfall and cholera incidence. Here, we show clear evidence for a shift in the distribution of cholera incidence throughout Africa in El Niño years, likely mediated by El Niño's impact on local climatic factors. Knowledge of this relationship between cholera and climate patterns coupled with ENSO forecasting could be used to notify countries in Africa when they are likely to see a major shift in their cholera risk
"We Are Part of a Family". Benefits and Limitations of Community ART Groups (CAGs) in Thyolo, Malawi: a Qualitative Study
No full textIn 2012 Community ART Groups (CAGs), a community-based model of antiretroviral therapy (ART) delivery were piloted in Thyolo District, Malawi as a way to overcome patient barriers to accessing treatment, and to decrease healthcare workers' workload. CAGs are self-formed groups of patients on ART taking turns to collect ART refills for all group members from the health facility. We conducted a qualitative study to assess the benefits and challenges of CAGs from patients' and healthcare workers' (HCWs) perspectives
Effect of Previous Treatment and Sputum Quality on Diagnostic Accuracy of Xpert(®) MTB/RIF
No full textIn early studies, Xpert® MTB/RIF accurately detected culture-proven pulmonary tuberculosis (TB). Recent reports have, however, found a lower than expected specificity in previously treated TB patients
