In an observational cohort study including 89 Ebola patients, predictive factors of death were analyzed. The crude mortality rate was 43.8%. Myalgia (adjusted odds ratio [OR], 4.04; P = .02), hemorrrhage (adjusted OR, 3.5; P = .02), and difficulty breathing (adjusted OR, 5.75; P = .01) were independently associated with death.

Background Keloids are a common presenting complaint in Black Africans but remain poorly documented in these populations. The aim of our study was to describe the epidemiological and clinical profiles of patients with keloids seen at dermatology outpatient consultations in Yaoundé (Cameroon) and to determine driving factors of keloid occurrence. Methods This was a 1 : 2 case–control study conducted from February to May 2016 at the dermatology unit of five health facilities in Yaoundé, Cameroon. Cases were patients with black skin and diagnosed with keloids while controls had no keloid scar, paired to cases according to age and sex. The diagnosis of keloid was based on clinical history and findings. Results Of 2,940 patients seen during the study period, 102 (54.9% females) had keloids, hence a prevalence of 3.5% (95% confidence interval [CI]: 2.8–4.2). The most affected age group was ≥25 years (69.6%). Lesions at the origin of keloids were mostly traumatic (66.7%). In 68 patients (66.7%), keloid scars were associated with pruritus. The presternal region was the predominant localization (26.5%). Existence of a family history of keloids was significantly associated with presence of keloids (adjusted odds ratio: 4.2, 95% CI: 2.4–7.2; P < 0.001). Conclusions Keloids commonly affect black skin as recorded during dermatology consultations in Yaoundé, Cameroon. More often, they are secondary to skin trauma and seem to occur among those with a family history of keloids. Therefore, these people should be closely monitored accordingly.

Although, the knowledge management (KM)-culture research has helped to validate the importance of cultural values for companies' KM initiatives and provided insights into some important values, it still lacks frameworks and analysis outlining how specific types of cultural values might relate to Knowledge Management system (KMS) adoption and subsequent outcomes. In this paper, we provide a three-dimensional framework to help managers articulate how culture affects their unit's ability to create, transfer, and apply knowledge through KMS use. To illustrate the application of the framework, we also present an exploratory case study we have performed in an international organization in the area of development assistance and capacity development.
