Randomized Controlled Trial
Comparison Between Ultrasound-Guided Supraclavicular and Interscalene Brachial Plexus Blocks in Patients Undergoing Arthroscopic Shoulder Surgery: A Prospective, Randomized, Parallel Study.
Although supraclavicular brachial plexus block (SCBPB) was repopularized by the introduction of ultrasound, its usefulness in shoulder surgery has not been widely reported. The objective of this study was to compare motor and sensory blockades, the incidence of side effects, and intraoperative opioid analgesic requirements between SCBPB and interscalene brachial plexus block (ISBPB) in patients undergoing arthroscopic shoulder surgery. Patients were randomly assigned to 1 of 2 groups (ISBPB group: n = 47; SCBPB group: n = 46). ⋯ No patient complained of subjective dyspnea. Despite the weaker degree of sensory blockade provided by SCBPB in comparison to ISBPB, opioid analgesic requirements are similar during arthroscopic shoulder surgery under both brachial plexus blocks. However, SCBPB produces a better motor blockade and a lower incidence of Horner's syndrome than ISBPB.

Case Reports
Case Report: Human Bocavirus Associated Pneumonia as Cause of Acute Injury, Cologne, Germany.
Although the human bocavirus (HBoV) is known since a decade, limited information about its pathogenesis is available due to the lack of an animal model. Thus, clinical cases and studies are the major source of novel information about the course of infection and the related pathophysiology. ⋯ During the initial phase, an acute active HBoV infection was confirmed by positive polymerase chain reactions from bronchoalveolar lavage fluid and serum. The case further demonstrates that HBoV can cause severe pneumonia, induce secondary disease also in adults, and may be associated with neurological symptoms as previously assumed.

Review Meta Analysis
Clinicopathologic Significance and Prognostic Value of B7 Homolog 1 in Gastric Cancer: A Systematic Review and Meta-Analysis.
Immunologic checkpoint marker B7 homolog 1 (B7-H1) plays a fundamental role in the initiation and progression of gastric cancer (GC); however, the clinicopathologic significance and prognostic value of B7-H1 in GC remains controversial. In this study, we aimed to assess their relationship through a meta-analysis. Medline/PubMed, EMBASE, the Cochrane Library databases, and Grey literature were searched up to August 10, 2015, for eligible studies of the association between B7-H1 expression and overall survival in GC. ⋯ The pooled results showed that positive B7-H1 expression was a negative predictor for overall survival with hazard ratio of 1.74 (95% CI: 1.40-2.17; Pheterogeneity = 0.146) in GC. Additionally, increased B7-H1 was found to be significantly associated with positive lymph node metastasis (OR = 2.61, 95% CI: 1.78-3.84; Pheterogeneity = 0.004) and poorer tumor stage (OR = 2.28, 95% CI: 1.39-3.74; Pheterogeneity = 0.006); however, higher B7-H1 expression was not significantly correlated with poorer tumor differentiation (OR = 1.29, 95% CI: 0.90-1.86; Pheterogeneity = 0.013) and bigger tumor size (OR = 1.18, 95% CI: 0.81-1.73; Pheterogeneity = 0.104). The meta-analysis suggested that B7-H1 could act as a significant biomarker in the poor prognosis of gastric carcinoma.

Review Meta Analysis
NF-κB Expression and Outcomes in Solid Tumors: A Systematic Review and Meta-Analysis.
Nuclear factor-kappaB (NF-κB) is a key inflammatory transcription factor expressed frequently in tumors. Numerous studies have investigated the correlation between NF-κB expression and prognosis in solid tumors, but the conclusions are still in contradiction. Here, we conduct a meta-analysis to explore the overall association of NF-κB overexpression and survival in human solid tumors. ⋯ There is no correlation between cellular localization of NF-kB overexpression and OS of solid tumors. Among the tumor types, NF-κB was associated with worse 3 year-OS of colorectal cancer (OR = 2.70, 95% CI = 1.64-4.46, P < 0.0001), esophageal carcinoma (OR = 6.00, 95% CI = 3.29-10.94, P < 0.0001) and worse 5 year-OS of colorectal cancer (OR = 2.72, 95% CI = 1.92-3.85, P < 0.00001), esophageal carcinoma (OR = 5.96, 95% CI = 3.48-10.18, P = 0.03), and nonsmall cell lung cancer (OR = 1.69, 95% CI = 1.20-2.38, P = 0.002). Expression of NF-κB is associated with worse survival in most solid tumors irrespective of NF-κB localization.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a poor prognosis. A number of studies reported the association between MUC5B promoter polymorphism rs35705950 and IPF, but substantial inconsistent findings were observed and the strength of association remains unclear. The aim of the study was to investigate the association between rs35705950 and IPF in different ethnic populations. ⋯ The strength of association was more remarkable in the Caucasian population than in the Asian population, and no homozygous TT genotype was detected in the Asian population in our study. Our study revealed strong association between the MUC5B promoter rs35705950 polymorphism and the risk of IPF. The strength of association between rs35705950 minor T allele and IPF susceptibility was particularly evident in the Caucasian population, and milder but still significant in the Asian population.
