Review Meta Analysis
The effect of a dual combination of noninsulin antidiabetic drugs on lipids: a systematic review and network meta-analysis.
As an ever widening array of anti-hyperglycemic agents are now available, the effect of these drugs on lipids is increasingly complex and controversial. The present meta-analysis was designed to clarify the effect of a dual combination of noninsulin anti-hyperglycemic agents on lipids in type 2 diabetes. ⋯ The effect of a dual combination of noninsulin anti-hyperglycemic agents on lipids is moderate to small, with metformin + DPP-4 inhibitor and metformin + GLP-1 agonist showing consistent beneficial effects on LDL cholesterol, HDL cholesterol, triglycerides and total cholesterol. Future trials are needed to confirm these findings.

Adrenal insufficiency is a rare but life-threatening disease. Conventional therapy consists of glucocorticoid replacement using hydrocortisone administered two or three times daily. Although such therapy extends life expectancy, mortality is not normalized, and quality of life remains poor. This failure to restore normal health is thought to be due to the inability of conventional glucocorticoid replacement therapy to normalize total cortisol exposure and to respond to the increased need for glucocorticoids during illness and stress. Also, current management regimens do not restore or replicate the intrinsic circadian rhythm of cortisol secretion. ⋯ Modified-release hydrocortisone treatments for patients with adrenal insufficiency more closely mimic the physiological circadian pattern of cortisol secretion than conventional twice or thrice daily treatment. The available evidence suggests that these modified-release preparations should improve metabolic outcomes and quality of life.

Comparative Study
Anti-tumor necrosis factor agents reduce corticosteroid use compared with azathioprine in patients with Crohn's disease.
Corticosteroids are effective for inducing remission of Crohn's disease, but should not be used long term due to risk of adverse events. Benefits of immunosuppressants (e.g., azathioprine) and anti tumor necrosis factor (anti-TNF) agents include reduced reliance on corticosteroid-based therapies and avoidance of corticosteroid-associated adverse events. Our aim was to evaluate corticosteroid-sparing effects in patients with Crohn's disease upon being newly initiated on an anti-TNFα agent or azathioprine. ⋯ Patients with Crohn's disease were able to avoid new prescriptions for corticosteroids at a statistically higher rate when treated with an anti-TNF agent. These results demonstrate that the anti-TNF agents are superior to azathioprine for minimizing exposure to corticosteroids.

Effects of canagliflozin, a sodium glucose co-transporter 2 inhibitor, on serum electrolytes were evaluated using pooled data from studies of patients with type 2 diabetes mellitus (T2DM). ⋯ In patients with T2DM, canagliflozin was generally associated with small mean percent changes in serum electrolytes. Infrequent episodes of potassium elevation occurred with canagliflozin 300 mg, but occurred more often in patients with reduced eGFR.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of a triple antiemetic regimen with aprepitant for the prevention of chemotherapy-induced nausea and vomiting: effects of gender, age, and region.
To determine the variability in treatment responses to antiemetic therapy (ondansetron and dexamethasone vs ondansetron and dexamethasone plus aprepitant) given with moderately emetogenic chemotherapy. ⋯ Although we acknowledge that subset numbers in this post hoc analysis may be too small to allow definitive conclusions, the data suggest that aprepitant triple therapy provides a benefit over control therapy for the prevention of CINV in patients receiving anthracycline and cyclophosphamide (AC)- or non-AC-based moderately emetogenic chemotherapy across age, gender, and region. (Original trial results available at ClinicalTrials.gov: NCT00337727.).
