Vitamin D insufficiency has deleterious consequences on health outcomes. In elderly or postmenopausal women, it may exacerbate osteoporosis. ⋯ The ESCEO recommends that 50 nmol/L (i.e. 20 ng/mL) should be the minimal serum 25-(OH)D concentration at the population level and in patients with osteoporosis to ensure optimal bone health. Below this threshold, supplementation is recommended at 800 to 1000 IU/day. Vitamin D supplementation is safe up to 10,000 IU/day (upper limit of safety) resulting in an upper limit of adequacy of 125 nmol/L 25-(OH)D. Daily consumption of calcium- and vitamin-D-fortified food products (e.g. yoghurt or milk) can help improve vitamin D intake. Above the threshold of 50 nmol/L, there is no clear evidence for additional benefits of supplementation. On the other hand, in fragile elderly subjects who are at elevated risk for falls and fracture, the ESCEO recommends a minimal serum 25-(OH)D level of 75 nmol/L (i.e. 30 ng/mL), for the greatest impact on fracture.

Randomized Controlled Trial Meta Analysis
Efficacy and safety of degludec insulin: a meta-analysis of randomised trials.
Degludec is a novel long-acting insulin analogue, providing an adequate supply of basal insulin over 24 hours with one daily injection, with a supposed greater reproducibility and flexibility than other basal insulins. ⋯ Degludec appears to be associated with a lower incidence of hypoglycaemia in comparison with glargine, for similar levels of glycaemic control. The use of this agent could represent one step further in insulin therapy.

Morbidity and mortality remain high for patients with invasive fungal infections (IFIs) despite an increasing number of antifungals and other treatments. Many studies indicate that delayed or inaccurate diagnosis and treatment are major causes of poor outcomes in patients with IFIs. ⋯ Better understanding of the strengths and weaknesses of currently available diagnostic tools, and further devising linked strategies to best implement them either alone or in combination, would greatly improve early and accurate diagnosis of IFIs and improve their successful management.

In-hospital mortality for ST-elevation myocardial infarction (STEMI) has declined thanks to a greater use of primary percutaneous coronary interventions (PCI) associated with more effective antiplatelet and anticoagulant drugs. In this regard, bivalirudin has been shown to decrease total and cardiac mortality as compared to unfractionated heparin (UFH). ⋯ Our research suggests that decreasing bleeding by either a pharmacologic strategy (use of bivalirudin) or a technical approach (the transradial access) improves survival in STEMI patients undergoing primary PCI. The validity of this hypothesis should be confirmed by specific randomized trials.

Multicenter Study Clinical Trial
Efficacy and safety of glimepiride as initial treatment in Chinese patients with Type 2 diabetes mellitus.
To investigate the efficacy and safety of glimepiride as initial mono-therapy in type 2 diabetes patients in China. ⋯ Glimepiride treatment as initial mono-therapy could effectively improve blood glucose control in type 2 diabetic patients, with a favorable safety profile. Lack of control group was the major limitation of this study. ClinicalTrial.gov identifier: NCT00908921.
