Chimpanzee Activity and Behavioral Diversity Extends Across 24 Hours in Both Captive and Wild Settings.

Studying nocturnal behavior is crucial for understanding the full scope of a species' behavioral flexibility so as to inform the conservation of wild populations and the care of captive individuals. However, this aspect of primate behavior is understudied, especially in great apes, which exhibit some of the widest documented behavioral diversity and flexibility. Our investigation is among the first to systematically compare the 24 h activity patterns and behavioral activities of captive chimpanzees (Saint Louis Zoo, USA) with those of wild chimpanzees (three sites across the Nouabalé-Ndoki National Park in the Republic of Congo) and a published data set of the nocturnal behavior of all chimpanzee subspecies.

Burnout syndrome among healthcare professionals in the Fako division, Cameroon: Impact of physical activity and sleep quality.

Objectives: Burnout syndrome (BOS) is an affection mostly resulting from chronic job-related stress. Many studies have identified job-related and non-job-related factors associated with BOS. Our aim of this study was to assess the level of BOS in private and public hospital healthcare providers in Fako division, Cameroon and evaluate the impact of physical activity and sleep quality (SQ).

Prevalence of the metabolic syndrome and its components in secondary school student population in the city of Douala, Cameroon.

While the burden of metabolic syndrome (MetS) is still increasing in sub-Saharan Africa, there is a lack of data among young Cameroonian population. The aim of this study was to evaluate the prevalence of MetS and its components among secondary school students in Douala. This was a cross-sectional prospective study carried out on 803 students recruited from February to May 2021 in public and private secondary schools in Douala city, Cameroon.

Extending the conservation impact of great ape research: Flagship species sites facilitate biodiversity assessments and land preservation.

To inform regional conservation planning, we assessed mammalian and avian biodiversity in the Djéké Triangle, which is an intact forest with long-term research and tourism focused on western lowland gorillas (Gorilla gorilla gorilla). This critical region serves as a conservation conduit between the Nouabalé-Ndoki National Park (NNNP) in the Republic of Congo and the Dzanga-Ndoki National Park in Central African Republic. Wildlife inventories were conducted to determine if biodiversity in the Djéké Triangle (initially part of a logging concession) was equivalent to the NNNP.

Musculoskeletal pains among amateur and professional athletes of five disciplines in Senegal: a preliminary study.

Background: Musculoskeletal pains (MSPs) in sport are cause of poor performances and loss of competition in athletes. The present study aimed at determining the prevalence of MSPs with regard to sport disciplines and athletic status.

Methods: A cross-sectional study was conducted among 320 Senegalese professional and amateur athletes practicing football, basketball, rugby, tennis, athletics, and wrestling.

Effect of a 12-week training program on the anthropometric and physiological profiles of some participants registered in a fitness center in Douala, Cameroon.

Fitness centers are remarkably abundant in Cameroon. The aim of this work was to assess the effects of a 12-week training program on the anthropometric and physiological profiles of some participants in a fitness center. A total of 86 participants (40 from the experimental group and 46 from the control group) with age ranging from 17 to 53 years were subjected to pre- and posttraining assessments of, anthropometric parameters, physiological parameters, and performance.

Epidemiology of burnout syndrome in four occupational sectors in Cameroon-impact of the practice of physical activities and sport.

Background: The purpose of this study was to determine the prevalence of Burnout syndrome (BOS), risk factors and the effect of physical activity in six professions in Cameroon.

Methods: 2012 participants completed questionnaires related to socio-demographic conditions and work perception. Appropriate Maslach Burnout Inventory (MBI) psychometers were used for specific professions.

Association of the leptin-to-adiponectin ratio with metabolic syndrome in a sub-Saharan African population.

Background: Worldwide there is an increased prevalence of metabolic syndrome mainly due to life-style modifications, and Africans are not saved of this situation. Many markers have been studied to predict the risk of this syndrome but the most used are leptin and adiponectin. Data on these metabolic markers are scare in Africa and this study aimed to assess the association between the leptin-to-adiponectin ratio (LAR) with metabolic syndrome in a Cameroonian population.

Association of serum leptin and adiponectin with anthropomorphic indices of obesity, blood lipids and insulin resistance in a Sub-Saharan African population.

Background: There is little data on the metabolic effects of adipokines in sub-Saharan African populations. This study aimed to explore the potential relationship of leptin and adiponectin, with obesity, plasma lipids and insulin resistance in a Cameroonian population.

Methods: We enrolled 167 men and 309 women aged ≥18 years from the general population in Cameroon.
