Adherence to nonnucleoside reverse transcriptase inhibitor-based HIV therapy and virologic outcomes.
Adherence of 95% or more to unboosted protease regimens is required for optimal virologic suppression in HIV-1-infected patients. Whether the same is true for nonnucleoside reverse transcriptase inhibitor (NNRTI)-based therapy is unclear. ⋯ Virologic outcomes improve in a linear dose-response manner as adherence to NNRTI-based regimens increases beyond 50%.

Randomized Controlled Trial Multicenter Study
Tiotropium in combination with placebo, salmeterol, or fluticasone-salmeterol for treatment of chronic obstructive pulmonary disease: a randomized trial.
Treatment of moderate or severe chronic obstructive pulmonary disease (COPD) with combinations of inhaled corticosteroids, long-acting beta-agonists, and long-acting anticholinergic bronchodilators is common but unstudied. ⋯ Addition of fluticasone-salmeterol to tiotropium therapy did not statistically influence rates of COPD exacerbation but did improve lung function, quality of life, and hospitalization rates in patients with moderate to severe COPD. International Standard Randomised Controlled Trial registration number: ISRCTN29870041.

Previous meta-analyses described moderate to large benefits of chondroitin in patients with osteoarthritis. However, recent large-scale trials did not find evidence of an effect. ⋯ Large-scale, methodologically sound trials indicate that the symptomatic benefit of chondroitin is minimal or nonexistent. Use of chondroitin in routine clinical practice should therefore be discouraged.

The risks and benefits of mammography screening among women 40 to 49 years of age remain an important issue for clinical practice. ⋯ Although few women 50 years of age or older have risks from mammography that outweigh the benefits, the evidence suggests that more women 40 to 49 years of age have such risks.
