Microbial Contamination and Food Safety Aspects of Cassava Roasted Flour ("Rale") in Mozambique.

Cassava is an important staple food that contributes to the food security of small-scale Mozambican farmers. In southern Mozambique, cassava roots are usually processed into cassava roasted flour, locally known as "rale". The handling and processing practices connected to "rale" production may introduce microbial contamination.

Persistent symptoms and clinical findings in adults with post-acute sequelae of COVID-19/post-COVID-19 syndrome in the second year after acute infection: A population-based, nested case-control study.

Background: Self-reported health problems following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are common and often include relatively non-specific complaints such as fatigue, exertional dyspnoea, concentration or memory disturbance and sleep problems. The long-term prognosis of such post-acute sequelae of COVID-19/post-COVID-19 syndrome (PCS) is unknown, and data finding and correlating organ dysfunction and pathology with self-reported symptoms in patients with non-recovery from PCS is scarce. We wanted to describe clinical characteristics and diagnostic findings among patients with PCS persisting for >1 year and assessed risk factors for PCS persistence versus improvement.

Spawning site selection by invasive Asian toads (Duttaphrynus melanostictus) in eastern Madagascar.

Background: Invasive species are a major threat to biodiversity on a global scale. Control strategies for these species could be improved by understanding and exploiting life history vulnerabilities. For example, most invasive anurans require waterbodies with specific characteristics for spawning; therefore, modifying these characteristics could influence spawning success.
