Objectives: The aim of this study was to investigate changes over six years in physical activity and sedentary behavior assessed with accelerometry in a representative sample of Swedish adults.
Design: A longitudinal study over six years.
Methods: The cohort consisted of 1172 participants (46% males) in 2002 and 511 participants (46% males) in 2008, of which 478 (45% males) had valid data on both occasions. Mean (SD) age at baseline was 45 (15) years. To analyze changes over time, a mixed linear model for average intensity physical activity (counts/min) and time in sedentary behavior and light- and moderate- or higher-intensity physical activity was conducted, stratified for sex and age, and adjusted for BMI, education, self-rated health and Δ wear time.
Results: Over a six year period no significant changes were seen in the total cohort for average intensity and time in moderate- or higher intensity physical activity. A significant decrease in average intensity physical activity was found for men (p=0.006) and those aged 60+ years at baseline (p<0.001). A significant increase (26 min/day) for sedentary time in the total cohort (p<0.001) and for time in moderate or higher intensity physical activity among women (p<0.001) and those aged 40-59 years at baseline (p=0.014) was found over the follow-up period.
Conclusions: The overall increase in sedentary time and decrease in average physical activity among men and the elderly are of concern, since they might result in an elevated risk of developing chronic diseases.

Obesity can change the immune microenvironment of adipose tissue and induce inflammation. This study is dedicated to exploring the internal mechanism by which different intensities of exercise reprogram the immune microenvironment of epididymal adipose tissue in nutritionally obese mice. C57BL/6J male obese mouse models were constructed by high-fat diet, which were respectively obese control group (OC), moderate intensity continuous exercise group (HF-M), high intensity continuous exercise group (HF-H) and high intensity intermittent exercise group (HF-T).

Importance: Evolving breast cancer treatments have led to improved outcomes but carry a substantial financial burden. The association of treatment costs with the cost-effectiveness of screening mammography is unknown.
Objective: To determine the cost-effectiveness of population-based breast cancer screening in the context of current treatment standards.

Background: Glucose transporter 1 deficiency syndrome (Glut1DS) was initially reported by De Vivo and colleagues in 1991. This disease arises from mutations in the SLC2A1 and presents with a broad clinical spectrum. It is a treatable neuro-metabolic condition, where prompt diagnosis and initiation of ketogenic dietary therapy can markedly enhance the prognosis.

Mild cognitive impairment (MCI) refers to cognitive alterations with preservation of functionality. Individuals with this diagnosis have a higher risk of developing dementia. Non-pharmacological interventions, such as physical exercise, are beneficial for the cognition of this population.
