True Prevalence of Unforeseen N2 Disease in NSCLC: A Systematic Review + Meta-Analysis.

Patients with unforeseen N2 (uN2) disease are traditionally considered to have an unfavorable prognosis. As preoperative and intraoperative mediastinal staging improved over time, the prevalence of uN2 changed. In this review, the current evidence on uN2 disease and its prevalence will be evaluated.

HOW WE DO IT: the Keystone flap for large skin defects: our experience with 30 consecutive cases.

Background: The keystone perforator-based fasciocutaneous island flap is a method of locoregional skin defect reconstruction, consisting of two conjoined V to Y advancement flaps. In this article, we report a series of 30 consecutive cases in various body parts with the aim to demonstrate the versatility of the keystone flap in the reconstruction of various skin defects after removal of a suspected malignant skin lesion and evaluate our clinical experience while maintaining oncological safety and good aesthetic results.

Methods: Patients who underwent keystone flap reconstruction between January 2016 and January 2021 were retrospectively reviewed.

Green tea catechins alleviate autoimmune symptoms and visual impairment in a murine model for human chronic intraocular inflammation by inhibiting Th17-associated pro-inflammatory gene expression.

Autoimmune uveitis is a sight-threatening disease mainly caused by dysregulation of immunity. We investigated the therapeutic effects of green tea extract (GTE) and its major component, epigallocatechin-3-gallate (EGCG), on a murine model of experimental autoimmune uveoretinitis (EAU). Oral administration of GTE, EGCG, dexamethasone, or water, which started 5 days before the induction, was fed every two days to each group.

Quality improvement strategies to prevent falls in older adults: a systematic review and network meta-analysis.

Background: Falls are a common occurrence and the most effective quality improvement (QI) strategies remain unclear.

Methods: We conducted a systematic review and network meta-analysis (NMA) to elucidate effective quality improvement (QI) strategies for falls prevention. Multiple databases were searched (inception-April 2017).

Comparisons of Interventions for Preventing Falls in Older Adults: A Systematic Review and Meta-analysis.

Importance: Falls result in substantial burden for patients and health care systems, and given the aging of the population worldwide, the incidence of falls continues to rise.

Objective: To assess the potential effectiveness of interventions for preventing falls.

Data Sources: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Ageline databases from inception until April 2017.

Knowledge synthesis methods for generating or refining theory: a scoping review reveals that little guidance is available.

Objectives: To describe and compare, through a scoping review, emerging knowledge synthesis methods for generating and refining theory, in terms of expertise required, similarities, differences, strengths, limitations, and steps involved in using the methods.

Study Design And Setting: Electronic databases (e.g.

A scoping review identifies multiple emerging knowledge synthesis methods, but few studies operationalize the method.

Objectives: To systematically identify, define, and classify emerging knowledge synthesis methods through a scoping review.

Study Design And Setting: MEDLINE, CINAHL, EMBASE, PsycINFO, the Cochrane Methodology Register, the Cochrane Database of Systematic Reviews, Social Sciences Abstracts, Library and Information Science Abstracts, Philosopher's Index, and Education Resources Information Center were searched to identify articles reporting emerging knowledge synthesis methods across the disciplines of health, education, sociology, and philosophy. Two reviewers independently selected studies and abstracted data for each article.

Seeking effective interventions to treat complex wounds: an overview of systematic reviews.

Background: Numerous, often multi-faceted regimens are available for treating complex wounds, yet the evidence of these interventions is recondite across the literature. We aimed to identify effective interventions to treat complex wounds through an overview of systematic reviews.

Methods: MEDLINE (OVID interface, 1946 until October 26, 2012), EMBASE (OVID interface, 1947 until October 26, 2012), and the Cochrane Database of Systematic Reviews (Issue 10 of 12, 2012) were searched on October 26, 2012.

Interventions to decrease the risk of adverse cardiac events for patients receiving chemotherapy and serotonin (5-HT3) receptor antagonists: a systematic review.

Background: Patients may experience nausea and vomiting when undergoing chemotherapy or surgery requiring anesthesia. Serotonin 5-hydroxytryptamine 3 (5-HT3) receptor antagonists are effective antiemetics, yet may cause adverse cardiac events, such as arrhythmia. We aimed to identify interventions that mitigate the cardiac risk of 5-HT3 receptor antagonists.

Relationship between road traffic noisescape and urban form in Hong Kong.

This paper reports on a study which explored the possible relationship between road traffic noisescape and urban form in Hong Kong. A total of 212 residential complexes from 11 contrasting urban forms were sampled, and their noise levels assessed both at dwelling and neighbourhood scales by noise mapping. Its findings indicate that residential complexes with different urban forms have significantly different noisescape attributes.

A high-throughput screening system for Arabidopsis transcription factors and its application to Med25-dependent transcriptional regulation.

The activities of transcription factors (TFs) require interactions with specific DNA sequences and other regulatory proteins. To detect such interactions in Arabidopsis, we developed a high-throughput screening system with a Gateway-compatible Gal4-AD-TF library of 1589 Arabidopsis TFs, which can be easily screened by mating-based yeast-one-hybrid (Y1H) and yeast-two-hybrid (Y2H) methods. The efficiency of the system was validated by examining two well-characterized TF-DNA and TF-protein interactions: the CHE-CCA1 promoter interaction by Y1H and NPR1-TGAs interactions by Y2H.

A splice-site mutation leads to haploinsufficiency of EXT2 mRNA for a dominant trait in a large family with multiple osteochondromas.

Multiple osteochondromas (MO) is an autosomal-dominant disorder and mutations in EXT1 and EXT2 account up to 78% of the cases studied, including missense, nonsense, frameshift, and splice-site mutations. EXT1 and EXT2 encode glycosyltransferases required for the synthesis of heparan sulfate (HS) chains. The molecular pathogenesis underlying these mutations is still largely unknown.

Inhibition of pyocyanin-potentiated IL-8 release by steroids in bronchial epithelial cells.

Airway epithelial cells are the first targets of environmental stimuli and local cytokines. Pyocyanin-induced synergism with interleukin (IL)-1 or tumour necrosis factor (TNF) in triggering IL-8 release has been documented previously. In this study, IL-8 mRNA and protein expression were examined in cultured human bronchial epithelial cells (BEAS-2B) stimulated with pyocyanin alone, and in combination with IL-1beta or phorbol 12,13-dibutyrate (PDBu) in the absence and presence of a group of glucocorticoids.
