Results: In total, 31 832 patients were included; 7066 (22.2%) were admitted on weekends, and 24 766 (77.8%) were admitted on weekdays. The mean (SD) age of patients was 60.8 (15.3) years, and 16 830 (52.9%) were female. A Hartmann procedure was performed in 4580 patients (64.8%) admitted on weekends compared with 13 351 patients (53.9%) admitted on weekdays (riskadjusted odds ratio [OR], 1.57;...

OBJECTIVES To investigate whether weekday-weekend differences in sedentary time and specific intensities of physical activity exist among children categorised by physical activity levels. DESIGN Cross-sectional observational study. METHODS Seven-day accelerometer data were obtained from 810 English children (n=420 girls) aged 10-11 years. Daily average minday(-1) spent in moderate to vigoro...

The ability of Gaussian noise to induce ordered states in dynamical systems is here presented in an overview of the main stochastic mechanisms able to generate spatial patterns. These mechanisms involve: (i) a deterministic local dynamics term, accounting for the local rate of variation of the field variable, (ii) a noise component (additive or multiplicative) accounting for the unavoidable env...

Localized ecological interactions can generate striking large-scale spatial patterns in ecosystems through spatial self-organization. Possible mechanisms include oscillating consumer-resource interactions, localized disturbance-recovery processes and scale-dependent feedback. Despite abundant theoretical literature, studies revealing spatial self-organization in real ecosystems are limited. Rec...

BACKGROUND Sepsis has a high prevalence, mortality-rate and cost. Sepsis patients usually enter the hospital through the Emergency Department (ED). Process or structural issues related to care may affect outcome. METHODS Multi-centered retrospective observational cohort study using administrative databases to identify adult patients (> = 18 years) with sepsis and severe sepsis admitted to Alb...

Leisure and vacation are generally associated with feelings of relaxation and well-being. However, there is also evidence suggesting that some people feel particularly ill and develop symptoms especially during weekends and vacations. The focal points of this article are the exploration of the antecedents and consequences of this phenomenon, pointing out the need of systematic research on its p...

In a large nationwide study in Spain, BARBA et al. [1] recently reported that patients admitted for treatment of an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) over a weekend showed poorer in-hospital survival compared to those admitted on weekdays. The data suggest that this effect is independent of confounders such as age, sex, comorbidity and respiratory failure. The...

Introduction: The effect of school day is a major factor in everyday rhythms during childhood and adolescence. relevance Physical Activity (PA) school-aged children raises the need to: (a) analyse whether Primary School pupils achieve recommended levels daily PA; (b) find out impact and, specifically, Education (PE) classes on PA compared to weekends; (c) explore differences according sex at th...

BACKGROUND Little has been reported on mortality following admissions at weekends for many gastrointestinal (GI) disorders. The aim was to establish whether GI disorders are susceptible to increased mortality following unscheduled admission on weekends compared with weekdays. METHODS Record linkage was undertaken of national administrative inpatient and mortality data for people in England an...
