Review Meta Analysis
Efficacy and Safety of Denosumab in Postmenopausal Women With Osteoporosis: A Meta-Analysis.
The purpose of this study was to perform a meta-analysis to examine the efficacy and safety of denosumab in postmenopausal women with osteoporosis. Medline, Cochrane Library, EMBASE, and Google Scholar databases were searched until October 30, 2014 using combinations of the following search terms: osteoporosis, postmenopause, postmenopausal, women, denosumab. The primary outcome was bone mineral density (BMD) change, and secondary outcomes were change in the bone turnover markers β-isomerized carboxy-terminal cross-linking telopeptide of type I collagen (CTX) and serum procollagen type I amino-terminal propeptide (P1NP), and adverse events. ⋯ Patients treated with denosumab had a significant decrease of CTX (-66.16%) and P1NP (-64.65%) as compared with those treated with placebo (both, P < 0.001). Adverse events were similar between the 2 groups (pooled odds ratio = 1.04, P = 0.625). Denosumab increases BMD and decreases markers of bone turnover in postmenopausal women with osteoporosis, and is not associated with significant side-effects.

Review Meta Analysis
Genetic Association Between CDKN1B rs2066827 Polymorphism and Susceptibility to Cancer.
Much attention has been directed to the association between cancer risk and rs2066827 polymorphism of the CDKN1B gene. However, the results are indefinitive and inconclusive. This study was devised to evaluate the hypothesis that rs2066827 polymorphism is associated with the risk of cancer. ⋯ A slightly deceased risk of cancer was also indicated in Caucasians consisting of 6707 cases and 8279 controls (pooled OR 0.91, 95% CI: 0.85-0.98; model, TG vs. TT). These data suggest that carriage of a TG genotype at rs2066827 polymorphism may be associated with decreased susceptibility to cancer, ovarian cancer in particular.

Randomized Controlled Trial
A Prospective Randomized Study Comparing Mini-surgical Percutaneous Dilatational Tracheostomy With Surgical and Classical Percutaneous Tracheostomy: A New Method Beyond Contraindications.
Although percutaneous dilatational tracheostomy (PDT) is more accessible and less time-demanding compared with surgical tracheostomy (ST), it has its own limitations. We introduced a modified PDT technique and brought some surgical knowledge to the bedside to overcome some standard percutaneous dilatational tracheostomy relative contraindications. PDT uses a blind route of tracheal access that usually requires perioperational imaging guidance to protect accidental injuries. ⋯ Interestingly, the most important improvement was performing msPDT on PDT-contraindicated patients with the complication rate comparable to surgical procedure.

Observational Study
Use of SSRI, But Not SNRI, Increased Upper and Lower Gastrointestinal Bleeding: A Nationwide Population-Based Cohort Study in Taiwan.
Selective serotonin receptor inhibitor (SSRI) and serotonin-noradrenaline reuptake inhibitor (SNRI) users have been reported to have an increased risk of upper gastrointestinal bleeding (UGIB), but their association with lower gastrointestinal bleeding (LGIB) is less studied. This study aimed to analyze the incidence of UGIB and LGIB among SSRI users, SNRI users, and controls. Using the National Health Insurance Research Database of Taiwan, 9753 subjects who were taking serotonin reuptake inhibitors (8809 with SSRIs, and 944 with SNRIs), and 39,012 age, sex, and enrollment time-matched controls were enrolled at a 1:4 ratio. ⋯ The use of SSRIs, but not SNRIs, was independently associated with an increased risk of UGIB (hazard ratio [HR]:1.97; 95% confidence interval [CI]: 1.67-2.31) and LGIB (HR: 2.96, 95% CI: 2.46-3.57) after adjusting for age, sex, underlying comorbidities, and medications. The long-term use of SSRIs significantly increased the risk of UGIB and LGIB, and caused more LGIB than UGIB in the general population after adjusting for possible confounding factors, but the association between SNRIs and GIB is insignificant. Further prospective studies are needed to clarify this important issue.

Observational Study
Sagittal Balance in Adolescent Idiopathic Scoliosis: A Radiographic Study of Spinopelvic Compensation After Selective Posterior Fusion of Thoracolumbar/Lumbar (Lenke 5C) Curves.
The relationship between spinal sagittal alignment and pelvic parameters is well known in adolescent idiopathic scoliosis. However, few studies have reported the sagittal spinopelvic relationship after selective posterior fusion of thoracolumbar/lumbar (TL/L) curves. We evaluated the relationship between spinal sagittal alignment and the pelvis, and analyzed how the pelvic sagittal state is adjusted in Lenke type 5C patients. ⋯ The pelvic state may be adjusted after selective posterior TL/L curve fusion in Lenke 5C adolescent idiopathic scoliosis patients. It is difficult to improve an anteverted pelvis in patients who have an LL that is increased by more than 11.6° or an SS that is increased by more than 4.7° after surgery. The anteverted pelvic state will generally occur with posterior correction surgery for patients with an LL that is greater than 63.7°, or an LL or SS that is respectively increased by more than 17.6° or 9.0° postoperatively.
