Despite the overwhelming female-predominance in chronic pain disorders, preclinical pain studies have historically excluded females as research subjects. Male-biased explanations of pathological pain mechanisms may not fully translate to pain processes in females, necessitating the exploration of pain processing and modulation in both sexes at the preclinical and clinical levels. This review highlights historical trends in the study of sex differences within the pain field and examines the current literature regarding new techniques for the mechanistic analysis of pain modulation in males and females. A large body of evidence suggests that sex differences exist at the molecular, cellular, and systems levels of pain processing, likely influenced by a combination of genetic, hormonal, and neuroimmune factors that may differ at distinct levels of the neuraxis.

Differences between private and public primary health care centers and differences between men and women in antihypertensive care and cardiovascular prevention in all patients with hypertension treated in primary care in Stockholm County, Sweden.
BMC Prim Care
January 2025
Division of Family Medicine and Primary Care, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Huddinge, Sweden.
Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).
Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.

Purpose: To evaluate the population variation in head-to-helmet contact forces in helmet users.
Methods: Four different size Kevlar composite helmets were instrumented with contact pressure sensors and chinstrap tension meters. A total number of 89 volunteers (25 female and 64 male volunteers) participated in the study.
Association between intraoperative fluid management and postoperative outcomes in living kidney donors: a retrospective cohort study.

Optimal fluid strategy for laparoscopic donor nephrectomy (LDN) remains unclear. LDN has been a domain for liberal fluid management to ensure graft perfusion, but this can result in adverse outcomes due to fluid overload. We compared postoperative outcome of living kidney donors according to the intraoperative fluid management.

BMJ Open
January 2025
Department of General Practice, University College Cork, Cork, Ireland
Objectives: To describe the prevalence of sub-optimal monitoring for selected higher-risk medicines in older community-dwelling adults and to evaluate patient characteristics and outcomes associated with sub-optimal monitoring.
Study Design: Retrospective observational study (2011-2015) using historical general practice-based cohort data and linked dispensing data from a national pharmacy claims database.
Setting: Irish primary care.
Objectives: This study aims to estimate the impact of the co-occurrence of behavioural risk factors on mortality in the Spanish adult population.
Design: Population-based cohort study based on data from the 2011-2012 Spanish National Health Survey and the 2014 European Health Survey (n=35 053 participants ≥15 years of age) both linked to mortality data as of December 2022. Risk factors included tobacco use, high-risk alcohol consumption, low adherence to the Mediterranean diet, leisure time sedentary lifestyle and body mass index outside the 18.
