TB among refugees from Ukraine in European countries.

Background: Since the Russian Federation's invasion of Ukraine, millions of refugees have moved to neighbouring European countries. We assessed the burden of TB in these refugees and surveyed screening approaches.

Methods: We conducted a survey among 30 European Union/European Economic Area and 13 other European countries, requesting population data on migrant residents and refugees with country of birth (COB) Ukraine, the number of TB notifications among people with COB Ukraine and countries' screening policies for refugees from Ukraine.

Factors influencing operationalization of Integrated Disease Surveillance in Malawi.

Objectives: Malawi's disease surveillance system is built on several different data sources and systems and is informed by the Integrated Diseases Surveillance and Response (IDSR) strategy. This study was carried out as part of a larger multicountry study to identify context-specific factors, which influence the operationalization of integrated disease surveillance.

Study Design And Methods: A total of six focus group discussions were conducted with 43 relevant personnel at the primary and secondary healthcare levels in two districts (Lilongwe and Dowa) and at the national level.

Updated Swedish advice on reducing the risk of sudden infant death syndrome.

Unlabelled: This article reviews updated advice and factual material from the Swedish National Board of Health and Welfare on reducing the risk of sudden infant death syndrome. Issues covered by the guidance for parents and healthcare professionals include sleeping positions, smoking, breastfeeding, bed sharing and using pacifiers.

Conclusion: The guidelines conclude that infants under three months of age are safest sleeping in their own cot and that a pacifier can be used when they are going to sleep.

Effect of urea on peptide conformation in water: molecular dynamics and experimental characterization.

Molecular dynamics simulations of a ribonuclease A C-peptide analog and a sequence variant were performed in water at 277 and 300 K and in 8 M urea to clarify the molecular denaturation mechanism induced by urea and the early events in protein unfolding. Spectroscopic characterization of the peptides showed that the C-peptide analog had a high alpha-helical content, which was not the case for the variant. In the simulations, interdependent side-chain interactions were responsible for the high stability of the alpha-helical C-peptide analog in the different solvents.
