Magnets and children: a dangerous combination.

Background: Accidental ingestion of foreign bodies is a common problem in children. Fortunately, the gastrointestinal tract is quite resilient to foreign bodies. On the other hand, the ingestion of magnets can result in enormous morbidity.

Long-term functioning status of COVID-19 survivors: a prospective observational evaluation of a cohort of patients surviving hospitalisation.

Objectives: The study investigated the long-term functional status of hospitalised COVID-19 survivors to explore and document their functional situation.

Design: This prospective observational study assessed 801 COVID-19 survivors at 3-11 months after hospital discharge. It analyses participants' sociodemographic background, COVID-19 clinical manifestations, and clinical and functional evaluations.

Development and test-retest reliability of a nutrition knowledge questionnaire for primary-school children.

Objective: To evaluate a web-based nutritional knowledge questionnaire for primary-school children.

Design: Children's nutritional knowledge was assessed in five domains: healthy choices (twenty-seven items), estimated recommended portions/servings (eight items), nutrient content (five items), main food function (five items) and categorization of food items (eight items).

Setting: The questionnaires were completed in school.

Efficacy of artesunate + sulfamethoxypyrazine/pyrimethamine versus praziquantel in the treatment of Schistosoma haematobium in children.

Background: This study was conducted to determine the efficacy of the antimalarial artemisinin-based combination therapy (ACT) artesunate +sulfamethoxypyrazine/pyrimethamine (As+SMP), administered in doses used for malaria, to treat Schistosoma haematobium in school aged children.

Methodology/principal Findings: The study was conducted in Djalakorodji, a peri-urban area of Bamako, Mali, using a double blind setup in which As+SMP was compared with praziquantel (PZQ). Urine samples were examined for Schistosoma haematobium on days -1, 0, 28 and 29.

Lipase-catalyzed ester exchange reactions in organic media with controlled humidity.

Immobilized lipase activity is studied in organic solvent systems of controlled water content under the influence of a variety of reaction parameters, such as temperature, relative humidity, substrate concentrations, and type of fatty acid used. Control of the amount of water in the reaction system was found to be a valuable tool for the orientation of the reaction process and for the determination of the final reaction products. The properties of the immobilized lipase were studied using the interesterification of triolein and palmitic acid as the model system.
