Reported associations between shiftwork and health have largely been based on occupation-specific, or single sex studies that might not be generalizable to the entire working population. The objective of this study was to investigate whether shiftwork was independently associated with obesity, diabetes, poor sleep, and well-being in a large, UK general population cohort. ⋯ Shiftwork was independently associated with multiple indicators of poor health and wellbeing, despite higher physical activity, and even in shiftworkers that did not work nights. Shiftwork is an emerging social factor that contributes to disease in the urban environment across the working population. Key messages Studies have linked shiftwork to obesity and diabetes in nurses and industry workers, but little is known about the implications of shiftwork for the general workforce In this large cross sectional study of UK workers, shiftwork was associated with obesity, depression and sleep disturbance, despite higher levels of physical activity. Shiftwork was associated with multiple indicators of compromised health and wellbeing and were more likely to report neurotic traits and evening preference.

The burden of stroke is increasing globally. Reports on seasonal variations in stroke occurrence are conflicting and long-term data are absent. ⋯ All major stroke subtypes occurred most commonly in autumn and most infrequently in summer. Seasonality of in-hospital mortality and length of hospital stay appears to vary by stroke subtype. The seasonal pattern of ischemic stroke occurrence appears to have changed during the past decades. Key messages All major stroke subtypes (ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage) occurred most frequently in autumn and least frequently in summer. Seasonal patterns of in-hospital mortality and length of stay differed markedly by stroke subtype. The seasonal pattern of ischemic stroke occurrence in Finland seems to have changed compared to 1982-1992.

Circadian rhythms are a critical part of the body's homeostatic mechanisms. These rhythms repeat with a cycle-length of approximately 24 h and are generated by a transcriptional-translational feedback loop. These rhythms are critical for proper behavioral, physiological, and molecular functions. ⋯ Key messages Chrono is a circadian clock gene whose transcription exhibits a robust circadian oscillation. CHRONO is a repressor of circadian transcriptional/translational feedback loops. CHRONO may function to link epigenetic control mechanisms to stress responses.

Review Meta Analysis
Significance of perioperative goal-directed hemodynamic approach in preventing postoperative complications in patients after cardiac surgery: a meta-analysis and systematic review.
Goal-directed hemodynamic therapy (GDT) is used to prevent hypoperfusion resulting from surgery. The objective of this study was to analyze the efficacy and importance of perioperative GDT. ⋯ GDT reduces the length of hospital stay compared with the standard of care. Further studies are necessary to continually assess the benefit of GDT following major surgery. Key Messages The results of this analysis revealed no significant difference between cardiac surgery patients receiving goal-directed hemodynamic therapy (GDT) or conventional fluid therapy in terms of the all-cause mortality, duration of mechanical intervention, and length of ICU-stay. The length of hospital stay was significantly reduced in patients treated with GDT compare to conventional fluid therapy. GDT may have limited benefit in reducing mortality; however, the association to shorter length of hospital stay may suggest that better hemodynamic balance can facilitate postoperative recovery.

Review Meta Analysis
Markers of atherosclerosis in patients with Cushing's syndrome: a meta-analysis of literature studies.
Several studies reported an increased cardiovascular (CV) risk in Cushing's syndrome (CS). We performed a meta-analysis on the impact of CS on major markers of atherosclerosis. ⋯ CS is significantly associated with markers of subclinical atherosclerosis and CV risk. These findings could help establish more specific CV prevention strategies in this clinical setting. Key messages A series of studies reported an increased cardiovascular risk in patients with Cushing's syndrome (CS). In the present meta-analysis we demonstrated that CS is associated with an increased intima-media thickness, higher prevalence of carotid plaques, and lower flow-mediated dilation as compared with controls. These data consistently suggest the need for a strict monitoring of early signs of subclinical atherosclerosis in CS patients.
