Predictors for survival in patients with bone metastasis of small cell lung cancer: A population-based study.

The objective of the current study is to analyze the clinical and demographic characteristics of patients with bone metastasis of small cell lung cancer (SCLC) and explore their survival predictors.We retrospectively extracted patients with bone metastasis of SCLC from the Surveillance, Epidemiology, and End Results database. We applied Cox regression analyses to identify independent survival predictor of overall survival (OS) and cancer-specific survival (CSS).

Program Website Evaluation of Canadian Obstetrics and Gynaecology Residency and Fellowship Programs.

Objective: The purpose of our study was to assess the comprehensiveness of Canadian obstetrics and gynaecology residency and fellowship program websites to understand the quality of information available to prospective students and make recommendations, if needed.

Methods: All active residency and fellowship program websites (as of May 2020) were evaluated and compared using 72-point criteria in the following domains: Recruitment, Faculty, Current Residents/Fellows, Research and Education, Surgical Procedures, Clinical Work, Benefits and Incentives, Wellness, and Environment. Programs without websites were excluded from the study.

Development and Validation of a Prognostic Nomogram for Extremity Soft Tissue Leiomyosarcoma.

Extremity soft tissue leiomyosarcoma (LMS) is a rare disease with a poor prognosis. The aim of this study is to develop nomograms to predict the overall survival (OS) and cancer-specific survival (CSS) of patients with extremity soft tissue LMS. Based on the Surveillance, Epidemiology, and End Results (SEER) database, 1,528 cases of extremity soft tissue LMS diagnosed between 1983 and 2015 were included.

The Treatment of Fibrosis of Joint Synovium and Frozen Shoulder by Smad4 Gene Silencing in Rats.

Soft tissue fibrosis at the joint induced by inflammation is the pathological basis of frozen shoulder. In the present study, we utilized a lentiviral approach to silence the Smad4 gene in an in vitro fibrosis model of fibroblasts and an in vivo frozen shoulder model. We observed the change in the fibrosis process and the biological indicators of frozen shoulder.

[AO elastic intramedullary nailing for the treatment of clavicle fractures].

Objective: To evaluate the outcome of Titanium elastic intramedullary nailing (TEN) for the treatment of displaced midclavicular fractures.

Methods: Between February 2010 and February 2013, 62 patients with displaced midclavicular fractures were treated by TEN, including 27 males and 35 females with an average age of 37.6 years old ranging from 15 to 67 years.

Inkjet printed Prussian blue films for hydrogen peroxide detection.

An inkjet printing method is described to fabricate hydrogen peroxide (H(2)O(2)) sensors. Insoluble Prussian blue (PB) nanoparticles were dispersed in aqueous solvent, and were printed on screen printed carbon electrodes with a piezoelectric inkjet printer for H(2)O(2) detection. The electrochemical behavior of the printed sensors was studied by using cyclic voltammetry and chronoamperometry.
