COVID-19 among migrants, refugees, and internally displaced persons: systematic review, meta-analysis and qualitative synthesis of the global empirical literature.

EClinicalMedicine

August 2024

Section Health Equity Studies & Migration, Department of Primary Care and Health Services Research, Heidelberg University Hospital, Im Neuenheimer Feld 130.3, Heidelberg 69120, Germany.

Background: Evidence amounted early that migrants, who are often side-lined in pandemic response or preparedness plans, are disproportionately affected by the COVID-19 pandemic and its consequences. However, synthesised evidence that quantifies the magnitude of inequalities in infection risk, disease outcomes, consequences of pandemic measures or that explains the underlying mechanisms is lacking.

Methods: We conducted a systematic review searching 25 databases and grey literature (12/2019 to 09/2023) and considered empirical articles covering migrants, refugees, asylum-seekers, and internally displaced persons reporting COVID-19 cases, hospitalisation, ICU admission, mortality, COVID-19 vaccination rates or health consequences of pandemic measures.

A typology of organizational readiness for change based on a latent profile analysis.

Front Psychol

December 2024

Department of Industrial/Organizational and Social Psychology, Institute of Psychology, Technical University Braunschweig, Braunschweig, Germany.

Companies have to undergo many change processes to succeed in the transforming economy. However, many change processes fail because employees are insufficiently accompanied through the process in a targeted manner. This study of N = 427 employees from a steel industry company undergoing a transformation process examines whether the organizational readiness for change (ORC) of highly affected employees can be classified into profiles, how these profiles can be predicted by various antecedents, and whether outcome variables such as job satisfaction can be explained by profile membership.

Front Sports Act Living

December 2024

Faculty of Business Management & Social Sciences, Hochschule Osnabrück, University of Applied Sciences, Osnabrück, Germany.

Introduction: While the impact of anthropogenic climate change on sports and the subsequent need for adaptation to evolving climatic conditions are acknowledged, there remains a notable paucity of scientific inquiry within the realm of sports and sports event studies specifically addressing climate change and its ramifications for event planning and management. Existing studies predominantly stem from health, medical, weather and climate science and mostly focus on mega-events and elite athlete contexts. Moreover, they often only focus on one specific impact (e.

Automated electrochemical oxygen sensing using a 3D-printed microfluidic lab-on-a-chip system.

Lab Chip

January 2025

Nanobioelectronics Laboratory (NBEL), Department of Biomedical Engineering, Ilse Katz Institute for Nanoscale Science and Technology, Ben-Gurion University of the Negev, 8410501 Beer Sheva, Israel.

Dissolved oxygen is crucial for metabolism, growth, and other complex physiological and pathological processes; however, standard physiological models (such as organ-on-chip systems) often use ambient oxygen levels, which do not reflect the lower levels that are typically found . Additionally, the local generation of reactive oxygen species (ROS; a key factor in physiological systems) is often overlooked in biology-mimicking models. Here, we present a microfluidic system that integrates electrochemical dissolved oxygen sensors with lab-on-a-chip technology to monitor the physiological oxygen concentrations and generate hydrogen peroxide (HO; a specific ROS).

To intubate or not? Balancing anesthesia in rodent fMRI: strategies to mitigate confounding effects.

Cereb Cortex

January 2025

Institute of Neuroscience and Medicine (INM-3), Research Center Juelich, Forschungszentrum Jülich, Wilhelm-Johnen-Strasse, 52425 Jülich, Germany.

More than a decade ago, the introduction of intubation and mechanical ventilation for performing blood oxygen level-dependent functional MRI studies in the rodent brain allowed an improved control over the physiological conditions during scanning sessions. An accurate understanding of respiratory parameters permits to respect the 3Rs in animal research, improves significantly the fMRI outcome, and promises improved translational studies. Developments also prompted a better comprehension on anesthetics and their impact on rodent brain physiology and function, bringing new insights on the buildup of carbon dioxide, interhemispheric connectivity, or arousal, which understanding are paramount for maturing better fMRI protocols in awake rodents.

Effective modifications for the buried interface between self-assembled monolayers (SAMs) and perovskites are vital for the development of efficient, stable inverted perovskite solar cells (PSCs) and their tandem photovoltaics. Herein, an ionic-liquid-SAM hybrid strategy is developed to synergistically optimize the uniformity of SAMs and the crystallization of perovskites above. Specifically, an ionic liquid of 1-butyl-3-methyl-1H-imidazol-3-iumbis((trifluoromethyl)sulfonyl)amide (BMIMTFSI) is incorporated into the SAM solution, enabling reduced surface roughness, improved wettability, and a more evenly distributed surface potential of the SAM film.

Karyotype changes are a formidable evolutionary force by directly impacting cross-incompatibility, gene dosage, genetic linkage, chromosome segregation, and meiotic recombination landscape. These changes often arise spontaneously and are commonly detected within plant lineages, even between closely related accessions. One element that can influence drastic karyotype changes after only one (or few) plant generations is the alteration of the centromere position, number, distribution, or even its strength.
