Low Back Pain Disparities in Portugal: A Population-Based Study Analysing the Role of Social Determinants of Health.

Introduction: Despite growing research, the relationship between social determinants of health (SDoH) and low back pain (LBP) remains inconsistent. This study aimed to investigate the associations between SDoH and self-reported LBP in the Portuguese population in 2019 and explore potential differences between rural and urban areas.

Methods: This is a cross-sectional study that includes 13,230 participants from the 2019 Portuguese National Health Interview Survey.

Absenteeism Among National Health Service Workers During the COVID-19 Pandemic in Portugal.

By March 2020, the first COVID-19 cases were detected in Portugal. Anecdotal evidence showed that the National Health Service absenteeism rate rose. The present study aimed to quantify and characterize the absenteeism rate among these healthcare workers during the COVID-19 pandemic in Portugal.

Effect of hypoxia and KCl depolarization in autofluorescence and ROS changes at the hippocampal CA3 area.

The increasing incidence of neurodegenerative and other diseases is considered to involve an excessive production of reactive oxygen species (ROS). Water supplies are often characterized by excessive organic waste that is decomposed by bacteria, using dissolved oxygen, leading to oxygen depletion. The potassium content of these waters may also affect negatively the mitochondrial metabolism and cellular ROS formation.

Metabolic Versatility of acetogens in syngas Fermentation: Responding to varying CO availability.

Syngas fermentation using acetogenic bacteria offers a promising route for sustainable chemical production. However, gas-liquid mass transfer limitations and efficient co-utilization of CO and H pose significant challenges. This study investigated the kinetics of syngas conversion to acetate by Acetobacterium wieringae and Clostridium species in batch conditions under varying initial CO partial pressures (19 - 110 kPa).
