Harms and benefits of sodium‑glucose co‑transporter 2 inhibitors
Sodium-glucose co-transporter 2 inhibitors are oral glucose-lowering drugs that increase the urinary excretion of glucose. In patients with type 2 diabetes and cardiovascular disease they reduce all-cause mortality, cardiac mortality, rates of hospitalisation for heart failure and the progression of renal disease.

Cumulative dispensing of high oral corticosteroid doses for treating asthma in Australia
Analysis of PBS dispensing data shows one-quarter of patients with asthma using inhaled corticosteroids are also dispensed potentially toxic amounts of oral corticosteroids. Cumulative amounts of prednisolone greater than 1 gram can elicit osteoporosis and fracture, diabetes, cataracts, weight gain, sleep apnoea, renal impairment, pneumonia, myocardial infarction, heart failure, stroke, dyslipidaemia, and depression.

Effects of Vitamin D and Marine Omega‐3 Fatty Acid Supplementation on Chronic Knee Pain
In the double‐blind, placebo‐controlled Vitamin D and Omega‐3 Trial (VITAL), over 25,000 US adults were randomized to receive vitamin D (2000IU/day), n‐3 FA (Omacor 1G/day) or placebo. Vitamin D and n‐3 FA supplementation for a mean of 5.3 years did not reduce knee pain or improve function or stiffness in the study. These results suggest that supplementation with vitamin D or n-3 FA does not play a role in the management of symptomatic knee pain due to OA.

In this 6-week randomized controlled trial, both as-needed and regular use of INCS had similar improvement in the total nasal symptom score and quality of life scores. The treatment effect was less sustained with as-needed use; however, as-needed use had half of INCS exposure of the regular use.
