Multicenter Study Observational Study
Vitamin D deficiency at admission is not associated with 90-day mortality in patients with severe sepsis or septic shock: Observational FINNAKI cohort study.
Introduction Low levels of vitamin D have been associated with increased mortality in patients that are critically ill. This study explored whether vitamin D levels were associated with 90-day mortality in severe sepsis or septic shock. Methods Plasma vitamin D levels were measured on admission to the intensive care unit (ICU) in a prospective multicentre observational study. ⋯ Conclusions Vitamin D deficiency detected upon ICU admission was not associated with 90-day mortality in patients with severe sepsis or septic shock. Key messages In severe sepsis and septic shock, a vitamin D deficiency upon ICU admission was not associated with increased mortality. Compared to patients with sufficient vitamin D, patients with deficient vitamin D more frequently exhibited diabetes, elevated C-reactive protein levels, and hospital-acquired infections upon ICU admission, and they more frequently developed acute kidney injury.

In this study, we investigated the independent and combined effects of sleep duration and afternoon napping on the risk of incident diabetes among a cohort of middle-aged and older Chinese adults. ⋯ Both long sleep duration and afternoon napping were independently and jointly associated with higher risk of incident diabetes. Key messages Sleep duration was associated with diabetes, but whether it is a real cause of incident diabetes especially in Chinese still remains to be elucidated. The association of afternoon napping and diabetes was not consistent and definite, we clarified this association in a large prospective study. Long sleep duration and afternoon napping were independently and jointly associated with higher risk of incident diabetes.

The association of diabetes with new-onset atrial fibrillation (AF) remains controversial. Hypertension may partly explain the risk association ascribed to diabetes. We studied the role and characteristics of diabetes in hypertensive patients with no ischemic vascular disease. ⋯ Diabetes was modestly associated with new-onset AF in hypertensive patients with no ischemic vascular disease. Among diabetic patients, only obesity reached significance in its association with this arrhythmia.

Disturbances of circadian rhythms are a key symptom of mood and anxiety disorders. Selective serotonin reuptake inhibitors (SSRIs) - commonly used antidepressant drugs - also modulate aspects of circadian rhythmicity. However, their potential to restore circadian disturbances in depression remains to be investigated. ⋯ The present findings provide evidence that fluoxetine treatment normalizes disrupted circadian locomotor activity and clock gene expression in a genetic mouse model of high trait anxiety and depression. An interaction between the molecular mechanisms mediating the antidepressant response to fluoxetine and the endogenous regulation of circadian rhythms in genetically based mood and anxiety disorders is proposed.

Sex differences in the association of HbA1c and cardiovascular disease (CVD) risk remain controversial. We examined CVD risk profile in both HbA1c-defined diabetic and nondiabetic men and women. ⋯ Men who progressed from HbA1c-defined nondiabetes to HbA1c-defined diabetes have greater metabolic deteriorations and put on more visceral adiposity than women. Key messages HbA1c-defined nondiabetic men have a more favorable CVD risk profile than female counterparts. Men have to undergo a greater metabolic deterioration to develop HbA1c-defined diabetes than do women. Men have to put on more visceral adiposity to develop HbA1c-defined diabetes than do women.
