4th booster-dose SARS-CoV-2 heterologous and homologous vaccination in rheumatological patients.

Objective: to evaluate the immune response to the SARS-CoV-2 vaccines in adults with immune-mediated rheumatic diseases (IMRDs) in comparison to healthy individuals, observed 1-20 weeks following the fourth vaccine dose. Additionally, to evaluate the impact of immunosuppressive therapies, vaccination schedules, the time interval between vaccination and sample collection on the vaccine's immune response.

Methods: We designed a longitudinal observational study conducted at the rheumatology department of Hospital de Copiapó.

Effects of Mediterranean Diet or Mindfulness-Based Stress Reduction during Pregnancy on Fetal Brain Development Detected by Neurosonography: A Secondary Analysis of a Randomized Clinical Trial (IMPACT BCN).

Introduction: We investigated whether structured maternal lifestyle interventions based on Mediterranean diet or stress reduction influence fetal-infant neurodevelopment detected by detailed fetal neurosonography and Ages and Stages Questionnaires 3rd edition (ASQ) at 12 months old.

Methods: This was a secondary analysis of a randomized clinical trial (2017-2020), including 1,221 singleton pregnancies at high risk for small-for-gestational age. Participants were randomized into three groups at 19-23 weeks' gestation: Mediterranean diet intervention, stress reduction program, or usual care.

Caregiver and Provider Perceptions of Health Disparities in the Neonatal Intensive Care Unit: A Qualitative Study.

Objective: 1) To describe the experience of caregivers and their perceptions of disparate care in the neonatal intensive care unit (NICU) and 2) explore interprofessional NICU provider perspectives on potential biases and perceptions of disparate care.

Methods: This qualitative study was conducted in 1 southeastern level IV NICU. Semistructured interviews assessed caregiver and provider perspectives on NICU care.

FetMRQC: A robust quality control system for multi-centric fetal brain MRI.

Fetal brain MRI is becoming an increasingly relevant complement to neurosonography for perinatal diagnosis, allowing fundamental insights into fetal brain development throughout gestation. However, uncontrolled fetal motion and heterogeneity in acquisition protocols lead to data of variable quality, potentially biasing the outcome of subsequent studies. We present FetMRQC, an open-source machine-learning framework for automated image quality assessment and quality control that is robust to domain shifts induced by the heterogeneity of clinical data.
