Background: Tobacco smoking is an important, modifiable, environmental risk factor for multiple sclerosis (MS) with a relevant impact on health-related quality of life (HRQOL). We aimed to assess the use of tobacco in individuals with MS from Latin America (LATAM), and its impact on HRQOL.
Methods: We conducted a cross-sectional study based on a LATAM web-based survey. Demographics, social and clinical data, information on physical disability, and HRQOL scores were collected using the MS Impact Scale-29 (MSIS-29), the Fatigue Severity Scale (FSS), and the Hospital Anxiety and Depression Scale-Anxiety (HADS-A). Individuals with MS were classified at the time of the survey as follows: never-smokers (ie, patients who reported they had never smoked), past smokers (those who had smoked tobacco but not during the past year), or current smokers. For the analysis, groups were compared.
Results: 425 patients (74.6% female) from 17 LATAM countries were included, mean age 43.6 ± 11 years and median Expanded Disability Status Scale score 2. There were 122 (28.7%) current smokers, 178 (41.9%) past smokers, and 125 (30.4%) never-smokers. Current smokers had significantly higher MSIS-29 physical (physical worsening), FSS (fatigue), and HADS-A (anxiety) scores compared with past and never-smokers after being adjusted for covariables. No significant differences were observed in any of the other analyzed demographic, clinical, and therapeutic variables. Thirty percent of the current and past smokers groups had never had their neurologists discuss smoking cessation with them.
Conclusions: Individuals with MS who were current smokers had higher fatigue and anxiety scores and worse HRQOL compared with past and never-smokers.

Introduction: People who are covered by Medicaid have a higher smoking prevalence than the general population and are at an increased risk for tobacco-related disease, a major driver of Medicaid costs. California has the largest Medicaid program, called Medi-Cal, whose members also have higher tobacco-use rates and tobacco-related disease. Quitting is beneficial at any age, and health professional advice and assistance are a key indicator of smoking cessation.

Commonly prescribed medications and risk of pneumonia and all-cause mortality in people with idiopathic pulmonary fibrosis: a UK population-based cohort study.
Pneumonia (Nathan)
January 2025
School of Public Health, Imperial College London, London, UK.
Background: A growing body of evidence suggests that prolonged use of inhaled corticosteroids (ICS) and proton pump inhibitors (PPIs) is associated with increased risks of pneumonia. A substantial proportion of people with idiopathic pulmonary fibrosis (IPF) are prescribed PPIs or ICS to treat common comorbidities, giving rise to concerns that use of these medications may be associated with potential harms in this patient population.
Methods: We used UK Clinical Practice Research Datalink (CPRD) Aurum primary care data linked to national mortality and hospital admissions data to create a cohort of people diagnosed with IPF on or after 1 January 2010.
