The limited existing literature studying the effects of childhood residential mobility suggests that it influences a range of life outcomes, at least in young adulthood. Little is known about how the frequency of moving in childhood is related to later-life demographic behaviour in Europe. Drawing on residential and partnership histories from the Survey of Health, Ageing and Retirement in Europe (SHARE), this paper examines whether moving in childhood relates to union dissolution in adulthood.

We developed mathematical models to analyze a large dengue virus (DENV) epidemic in Reunion Island in 2018-2019. Our models captured major drivers of uncertainty including the complex relationship between climate and DENV transmission, temperature trends, and underreporting. Early assessment correctly concluded that persistence of DENV transmission during the austral winter 2018 was likely and that the second epidemic wave would be larger than the first one.

Background: Data on effects of intra-gastric balloon (IGB) on metabolic dysfunction-associated steatotic liver disease (MASLD) are scarce, in part with contradictory results, and mainly obtained in tertiary care patients with diabetes and other comorbidities. We here explore effects of IGB in patients with MASLD referred to a first-line obesity clinic.

Methods: In this prospective cohort study, patients with at least significant fibrosis (≥ F2) and/or severe steatosis (S3) according to screening transient elastography (FibroScan®) were offered a second FibroScan® after 6 months lifestyle modification with or without IGB (based on patient preference).

  • Serological testing for Lyme borreliosis (LB) in patients with erythema migrans (EM) is not advised per European guidelines, prompting a study on French general practitioners' (GPs) adherence to these recommendations.
  • The study included 1,831 EM cases and found that only 24.0% resulted in a serological test prescription, showing a significant decline from 46.8% in 2009 to 15.8% in 2020.
  • Key factors leading to serological test prescriptions included the absence of a reported tick bite, presence of multiple EM lesions, larger EM size, and GPs who diagnosed fewer than one EM case per year, indicating a
