Article Synopsis
  • Acute respiratory infections are a major global health issue, and more research is needed on the microorganisms causing these infections in various regions, particularly in Senegal.
  • In a study of 500 febrile patients, researchers found that 73.2% had at least one detectable microorganism, with viruses and bacteria commonly identified, including influenza and RSV.
  • The presence of certain microorganisms was linked to respiratory symptoms, and co-infections were also associated with more severe symptoms, highlighting the need for better diagnostic tools to adapt treatment strategies.

Article Synopsis
  • Heart failure (HF) and arrhythmia-related complications significantly impact patients with nonischemic dilated cardiomyopathy (NIDCM), and this study investigates the prognostic value of cardiovascular magnetic resonance (CMR) imaging metrics like T1 and extracellular volume (ECV) for predicting these events.
  • Analyzing 225 NIDCM patients over two years, the study found 26% experienced major adverse cardiovascular events (MACE), with a notable association between increased ECV and HF-related events, while higher T1 Z-scores and ECV values correlated with arrhythmia-related events.
  • The study concluded that specific cutoffs for ECV and T1 Z-scores can be important independent predictors of both

Background: Diet and physical activity are key components of healthy aging. Current interventions that promote healthy eating and physical activity among the elderly have limitations and evidence of French interventions' effectiveness is lacking. We aim to assess (i) the effectiveness of a combined diet/physical activity intervention (the "ALAPAGE" program) on older peoples' eating behaviors, physical activity and fitness levels, quality of life, and feelings of loneliness; (ii) the intervention's process and (iii) its cost effectiveness.

We evaluated the age-specific mortality of unselected adult outpatients infected with SARS-CoV-2 treated early in a dedicated COVID-19 day hospital and we assessed whether the use of hydroxychloroquine (HCQ) + azithromycin (AZ) was associated with improved survival in this cohort. A retrospective monocentric cohort study was conducted in the day hospital of our center from March to December 2020 in adults with PCR-proven infection who were treated as outpatients with a standardized protocol. The primary endpoint was 6-week mortality, and secondary endpoints were transfer to the intensive care unit and hospitalization rate.

Introduction: Rural areas are considered safe havens against the increased spread of COVID-19 and associated restrictive measures, especially in contexts where public authorities are not in a position to systematically and substantially ease COVID-19-induced economic shocks. In the current sub-Saharan Africa context, still marked by uncertainty surrounding the spread of COVID-19, we present the protocol of an ongoing longitudinal study aimed at investigating COVID-19-related attitudes, risks perceptions, preventive behaviours and economic impact in rural areas in Senegal.

Methods And Analysis: A prospective randomised longitudinal study of 600 households located in three semiurban villages and nine randomly selected rural villages in the Niakhar area (located 135 km East of Dakar).

Patients with cancer are at higher risk of severe coronavirus infectious disease 2019 (COVID-19), but the mechanisms underlying virus-host interactions during cancer therapies remain elusive. When comparing nasopharyngeal swabs from cancer and noncancer patients for RT-qPCR cycle thresholds measuring acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in 1063 patients (58% with cancer), we found that malignant disease favors the magnitude and duration of viral RNA shedding concomitant with prolonged serum elevations of type 1 IFN that anticorrelated with anti-RBD IgG antibodies. Cancer patients with a prolonged SARS-CoV-2 RNA detection exhibited the typical immunopathology of severe COVID-19 at the early phase of infection including circulation of immature neutrophils, depletion of nonconventional monocytes, and a general lymphopenia that, however, was accompanied by a rise in plasmablasts, activated follicular T-helper cells, and non-naive Granzyme BFasL, EomesTCF-1, PD-1CD8 Tc1 cells.

Article Synopsis
  • Gut microbial dysbiosis, particularly the absence of Methanobrevibacter smithii, is linked to severe acute malnutrition (SAM), suggesting issues in energy harvesting.
  • A case-control study in Mali showed that M. smithii was found in 40.9% of healthy controls but only in 4.2% of SAM cases, indicating a significant association between its absence and SAM (p < 0.0001).
  • The results imply that gut dysbiosis in SAM points to a loss of M. smithii rather than an immaturity, suggesting that introducing M. smithii as a probiotic could help restore gut health in malnourished children.
