Purpose: Significant improvements in the prognosis for young patients with Primary Immunodeficiency Diseases (PID) and Autoinflammatory Disorders (AID), which together make up the majority of Inborn Errors of Immunity (IEI), have resulted in the need for optimisation of transition and transfer of care to adult services. Effective transition is crucial to improve health outcomes and treatment compliance among patients. Evaluations of existing transition programmes in European health centres identified the absence of disease-specific transition guidelines for PID and AID, as a challenge to the transition process.

Background: The Middle East and North African (MENA) region is a major global hotspot for migration with more than 40 million migrants, who may be an under-vaccinated group because of barriers to vaccination within countries of origin, transit, and destination. We systematically synthesised the evidence on coverage, acceptance, drivers of uptake, and policies pertaining to vaccination for children and adult migrants in the region, in order to explore tailored interventions for these groups.

Methods: We searched six databases (including Medline, Embase) for peer-reviewed literature, and other websites (including WHO, IOM, ministries of health) for grey literature on coverage, acceptance, drivers of uptake and policies for any vaccination in migrants in the MENA region from between 2000 and 27 August 2024 in any language.

A respiration rate (RR) monitoring system was created by integrating a Fibre Bragg Grating (FBG) optical fibre sensor into a respirator mask. The system exploits the sensitivity of an FBG to temperature to identify an individual's RR by measuring airflow temperature variation near the nostrils and mouth. To monitor the FBG response, a portable, battery-powered, wireless miniature interrogator system was developed to replace a relatively bulky benchtop interrogator used in previous studies.

Experimental and Clinical Research Center, a Cooperation Between Max Delbrück Center for Molecular Medicine in the Helmholtz Association, Charité - Universitätsmedizin Berlin, Geschäftsführung, Charitéplatz 1, 10117, Berlin, Germany.

Quantitative magnetic resonance imaging (qMRI) involves mapping microstructure in standardized units sensitive to histological properties and supplements conventional MRI, which relies on contrast weighted images where intensities have no biophysical meaning. While measuring tissue properties such as myelin, iron or water content is desired in a disease context, qMRI changes may typically reflect mixed influences from aging or pre-clinical degeneration. We used a fast multi-parameter mapping (MPM) protocol for clinical routine at 3T to reconstruct whole-brain quantitative maps of magnetization transfer saturation (MT), proton density (PD), longitudinal (R1), and transverse relaxation rate (R2*) with 1.
