Methods for Developing Evidence Reviews in Short Periods of Time: A Scoping Review.

Introduction: Rapid reviews (RR), using abbreviated systematic review (SR) methods, are becoming more popular among decision-makers. This World Health Organization commissioned study sought to summarize RR methods, identify differences, and highlight potential biases between RR and SR.

Methods: Review of RR methods (Key Question 1 [KQ1]), meta-epidemiologic studies comparing reliability/ validity of RR and SR methods (KQ2), and their potential associated biases (KQ3).

Role of the levonorgestrel intrauterine system in effective contraception.

Norgestrel, a synthetic progestin chemically derived from 19-nortestosterone, is six times more potent than progesterone, with variable binding affinity to various steroid receptors. The levonorgestrel-releasing intrauterine system (LNG IUS) provides a long-acting, highly effective, and reversible form of contraception, with a pearl index of 0.18 per 100 women-years.

Gonadotrophins for idiopathic male factor subfertility.

Background: Male factors leading to subfertility account for at least half of all cases of subfertility worldwide. Although some causes of male subfertility are treatable, treatment of idiopathic male factor subfertility remains empirical. Researchers have used gonadotrophins to improve sperm parameters in idiopathic male factor subfertility with the ultimate goal of increasing birth and pregnancy rates, but results have been conflicting.

Metformin added to insulin therapy for type 1 diabetes mellitus in adolescents.

Background: In adolescents with type 1 diabetes, insulin resistance likely plays a role in the deterioration of metabolic control. In type 1 diabetes, addition of metformin to insulin therapy, to improve insulin sensitivity, has been assessed in a few trials involving few patients or in uncontrolled studies of short duration. No systematic reviews are available up to date to summarize the evidence about metformin addition to insulin therapy in adolescents with type 1 diabetes.
