Review Meta Analysis
Levonorgestrel-releasing intrauterine system versus medical therapy for menorrhagia: a systematic review and meta-analysis.
The aim of this study was to compare the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) with conventional medical treatment in reducing heavy menstrual bleeding. ⋯ The LNG-IUS was the more effective first choice for management of menorrhagia compared with conventional medical treatment. Long-term, randomized trials are required to further investigate patient-based outcomes and evaluate the cost-effectiveness of the LNG-IUS and other medical treatments.

Meta Analysis
Dexamethasone reduces nausea and vomiting but not pain after thyroid surgery: a meta-analysis of randomized controlled trials.
Postoperative nausea and vomiting (PONV) is a common complication after thyroidectomy. The aim of this article was to evaluate the efficacy of dexamethasone for prevention of PONV and pain in patients undergoing thyroidectomy. ⋯ A single preoperative administration of dexamethasone reduced the incidence and severity of PONV but not pain severity and analgesic consumption in patients undergoing thyroidectomy. Further studies with a larger sample size are needed to further explore the efficacy of dexamethasone on postoperative pain severity and analgesic consumption.

Postoperative cognitive dysfunction (POCD) is a subtle disorder of thought processes, which may influence isolated domains of cognition and has a significant impact on patient health. The reported incidence of POCD varies enormously due to lack of formal criteria for the assessment and diagnosis of POCD. ⋯ The release of cytokines due to the systemic stress response caused by anesthesia and surgical procedures might induce the changes of brain function and be involved in the development of postoperative cognitive dysfunction. The strategies for management of POCD should be a multimodal approach involving close cooperation between the anesthesiologist, surgeon, geriatricians, and family members to promote early rehabilitation and avoid loss of independence in these patients.

Meta Analysis
Efficacy and safety of bone marrow cell transplantation for chronic ischemic heart disease: a meta-analysis.
Although bone marrow-derived cells (BMCs) have shown great therapeutic potential in patients with chronic ischemic heart disease (CIHD), the exact efficacy and safety of BMCs therapy is still not completely defined. ⋯ Autologous transplantation of BMCs was safe and effective for patients who were candidates for revascularization with CABG/PCI and those who were not. However, large clinical trials and long-term follow-up are required to confirm these benefits.

Randomized Controlled Trial Comparative Study
Pyriform sinus localization-assisted blind intubation: comparison with laryngoscopic intubation.
Conventional endotracheal intubation requires laryngoscopy for a direct view of the glottis. However, laryngoscopy is associated with many potential complications. The aim of the present study was to compare the efficacy and safety of pyriform sinus localization-assisted blind orotracheal intubation with those of conventional laryngoscopic orotracheal intubation. ⋯ Pyriform sinus localization-assisted blind orotracheal intubation was shown to be more effective than conventional laryngoscopic orotracheal intubation in terms of success rate, intubation time, and postoperative complication rate. Moreover, it is less affected by common risk factors; thus, this method may be more beneficial in patients with difficult airways.
