Ostéoporose et évaluation du risque fracturaire par l’outil frax chez des patients Congolais présentant un rhumatisme axial : Une série des cas multicentriques
Contexte et objectif. L’enjeu majeur dans le management de l’ostéoporose est l’identification des sujets à risque par la quantification du risque fracturaire. L’objectif de l’étude était d’évaluer le risque fracturaire chez les patients ayant consulté pour douleur du squelette axial. Méthodes. Il s’agissait d’une série des cas multicentriques menée sur des patients recrutés dans 8 hôpitaux de Kinshasa. Les paramètres d’intérêt comme l’âge, le sexe, l’alcoolisme, le tabagisme, la fracture de hanche chez un parent de 1er degré ou une fracture personnelle de fragilité ont été collectés auprès de chaque patient. La mesure de la densité osseuse avait été réalisée par absorptiométrie biphotonique à rayons X. Le risqué fracturaire a été évalué par le calcul de l’indice fracturaire FRAX. Ce risque était élevé lorsque la probabilité de survenue de fracture de hanche était ≥ 3% et/ou des fractures ostéoporotiques majeures ≥ 20%. Des tests statistiques usuels ont été utilisés pour l’analyse des résultats. Résultats. 90 patients dont 75 femmes étaient inclus. Leur âge moyen était de 63,5±12 ans. L’ostéoporose était diagnostiquée chez 34,4% des patients, l’ostéopénie chez 43,9% et 16,7% avaient une densité minérale osseuse normale. Aucune fracture ostéoporotique n’a été observée dans la présente étude, mais près de 30% de l’ensemble de l’échantillon avaient un risque fracturaire élevé. L’ostéoporose était associée, dans environ 80% des cas (p<0,005), à un risqué fracturaire élevé. Conclusion. La présente étude a montré que le risque fracturaire était élevé chez les patients atteints d’ostéoporose. Elle met en lumière la nécessité d’un dépistage précoce de cette pathologie.
English title: Osteoporosis and assessment of fracturary risk using the frax tool in Congolese patients with axial rheumatism: A multicenter case series
Context and objective. The major challenge in the management of osteoporosis is the identification of subjects at risk by quantifying the fracture risk in order to prevent the fracture cascade. The aim of the present study was to evaluate the fracture risk in patients who had consulted for axial skeletal pain. Methods. This was a multicenter case series carried out on patients with axial rheumatism recruited in 8 hospitals in Kinshasa. The parameters of interest such as age, sex, alcoholism, smoking, hip fracture in a 1st degree relative or personal fragility fracture were collected from each patient. Bone mineral density was measured by dual energy x-ray absorptiometry. Fracture risk was assessed by calculating the FRAX fracture index. This risk was considered high when the probability of occurrence of a hip fracture was ≥ 3% and/or major osteoporotic fractures ≥ 20%. Standard statistical tests were used to analyze the results. Results. 90 patients including 75 women (83.3%) were involved. Their average age was 63.5±12 years. Osteoporosis was diagnosed in 34.4% of patients, osteopenia in 43.9% of patients and 16.7% of patients had normal bone mineral density. No osteoporotic fractures were observed, but nearly 30% of the entire sample had a high fracture risk. Osteoporosis (T-score ≤-2.5) was associated, in approximately 80% of cases (p<0.005), with a high fracture risk. Conclusion. The present study showed that fracture risk was very high in patients with osteoporosis. It highlights the need for early detection of this pathology.

Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats
In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security
Transformative learning for a sustainable and healthy future through ecosystem approaches to health: insights from 15 years of co-designed ecohealth teaching and learning experiences
This paper presents insights from the work of the Canadian Community of Practice in Ecosystem Approaches to Health (CoPEH-Canada) and 15 years (2008–2022) of land-based, transdisciplinary, learner-centred, transformative learning and training. We have oriented our learning approaches to Head, Hands, and Heart, which symbolise cognitive, psychomotor, and affective learning, respectively. Psychomotor and affective learning are necessary to grapple with and enact far-reaching structural changes (eg, decolonisation) needed to rekindle healthier, reciprocal relationships with nature and each other. We acknowledge that these approaches have been long understood by Indigenous colleagues and communities. We have developed a suite of teaching techniques and resources through an iterative and evolving pedagogy based on participatory approaches and operating reciprocal, research-pedagogical cycles; integrated different approaches and ways of knowing into our pedagogy; and built a networked Community of Practice for continued learning. Planetary health has become a dominant framing for health-ecosystem interactions. This Viewpoint underscores the depth of existing scholarship, collaboration, and pedagogical expertise in ecohealth teaching and learning that can inform planetary health education approaches.University of Northern British ColumbiaRevisión por pare

Spillover of ebolaviruses into people in eastern Democratic Republic of Congo prior to the 2018 Ebola virus disease outbreak
Background
The second largest Ebola virus disease (EVD) outbreak began in the Democratic Republic of Congo in July 2018 in North Kivu Province. Data suggest the outbreak is not epidemiologically linked to the 2018 outbreak in Equateur Province, and that independent introduction of Ebola virus (EBOV) into humans occurred. We tested for antibodies to ebolaviruses in febrile patients seeking care in North Kivu Province prior to the EVD outbreak.
Methods
Patients were enrolled between May 2017 and April 2018, before the declared start of the outbreak in eastern DRC. Questionnaires were administered to collect demographic and behavioural information to identify risk factors for exposure. Biological samples were evaluated for ebolavirus nucleic acid, and for antibodies to ebolaviruses. Prevalence of exposure was calculated, and demographic factors evaluated for associations with ebolavirus serostatus.
Results
Samples were collected and tested from 272 people seeking care in the Rutshuru Health Zone in North Kivu Province. All patients were negative for filoviruses by PCR. Intial screening by indirect ELISA found that 30 people were reactive to EBOV-rGP. Results were supported by detection of ebolavirus reactive linear peptides using the Serochip platform. Differential screening of all reactive serum samples against the rGP of all six ebolaviruses and Marburg virus (MARV) showed that 29 people exhibited the strongest reactivity to EBOV and one to Bombali virus (BOMV), and western blotting confirmed results. Titers ranged from 1:100 to 1:12,800. Although both sexes and all ages tested positive for antibodies, women were significantly more likely to be positive and the majority of positives were in February 2018.
Conclusions
We provide the first documented evidence of exposure to Ebola virus in people in eastern DRC. We detected antibodies to EBOV in 10% of febrile patients seeking healthcare prior to the declaration of the 2018–2020 outbreak, suggesting early cases may have been missed or exposure ocurred without associated illness. We also report the first known detection of antibodies to BOMV, previously detected in bats in West and East Africa, and show that human exposure to BOMV has occurred. Our data suggest human exposure to ebolaviruses may be more frequent and geographically widespread

Heterogeneity in patterns of helminth infections across populations of mountain gorillas (Gorilla beringei beringei)
Conservation efforts have led to the recovery of the endangered mountain gorilla populations. Due to their limited potential for spatial expansion, population densities increased, which may alter the epidemiology of infectious diseases. Recently, clinical gastrointestinal illnesses linked to helminth infections have been recorded in both gorilla populations. To understand drivers and patterns of helminth infections we quantified strongylid and tapeworm infections across both Virunga Massif and Bwindi populations using fecal egg counts. We assessed the impact of age, sex, group size, season and spatial differences used as a proxy, which reflects observed variation in the occurrence of gastrointestinal problems, vegetation types, gorilla subpopulation growth and associated social structure on helminth infections. We revealed striking geographic differences in strongylid infections with higher egg counts mostly in areas with high occurrences of gastrointestinal disease. Increased helminth egg counts were also associated with decreasing group size in some areas. Observed spatial differences may reflect mutual effects of variations in subpopulation growth rates, gorilla social structure, and vegetation associated with altitude across mountain gorilla habitat. Helminth infection intensities in Virunga gorillas were lowest in the youngest and the oldest animals. Elucidating parasite infection patterns of endangered species with low genetic diversity is crucial for their conservation management
