Postoperative infections are a common complication. A relationship between perioperative severe hyperglycemia and postoperative infections has been found in patients undergoing craniotomy. The aim of this study is to evaluate the epidemiology of intraoperative severe hyperglycemia (BGC >180 mg/dL; 10 mmol/L) and postoperative infections (wound, urinary and prosthetic joint infection) and to investigate if severe intraoperative hyperglycemia is associated with an higher risk of early postoperative (within the 7th postoperative days) infections (wound, urinary and prosthetic joint infection).

Suicide attempts (SA) constitute a major public health issue worldwide. Research suggests that 2.7% of adult people ever attempt suicide; among children and adolescents this is estimated to be 6.0%. SA are related to subsequent suicide which represents an annual loss of 34.6 million years of life worldwide. Suicide attempts are also related to persistent physical and mental health issues, psychiatric hospitalizations, impaired academic performance, unemployment, partner abuse victimization and perpetration, having children removed by social services, loneliness, relationship difficulties, impaired social functioning and low life satisfaction. Despite this considerable societal impact, there is a lack of epidemiological research focussing on providing suicide attempt surveillance in the population, to inform public health action aimed at reducing risk for suicide attempts in the population, and to provide data-driven support for suicide risk assessment across healthcare settings. To address this shortcoming, the investigators designed the Catalonia Suicide Risk Code Epidemiology study. Using centralized Electronic Healthcare Record data from the entire public healthcare system of Catalonia, Spain, the CSRC-Epi study aims to estimate reliable suicide incidence rates, identify suicide attempt risk factors, and develop validated suicide attempt risk prediction tools.

In previous studies, the investigators used retrospective analysis of cases of acute upper gastrointestinal bleeding in patients with liver cirrhosis from the Fifth Medical Center of the General Hospital of Beijing PLA, China from January 2018 to May 2019. The investigators performed univariate and multivariate analyses of rebleeding risk and death risk based on all data. Then, based on the analysis of 85% of the sampled data, the investigators randomly selected 85% of the patient data to build a model, and then used the remaining 15% of the patient data for model validation. Re-bleeding risk scores and death risk scores were established, respectively. This study intends to prospectively verify the two risk scoring systems described above. After statistical calculations, about 500 patients with liver cirrhosis who plan to undergo emergency gastroscopy for acute upper gastrointestinal bleeding within the next 5 months at the Fifth Medical Center of Beijing General Hospital of China performed in adult patients. The investigators will exclude patients with incomplete or lost follow-up records. Perform patient self-control,using the existing upper gastrointestinal bleeding risk scores (AIMS65, Rockall, and Blatchford) and the previous scoring system model separately, compared with the actual rebleeding rate and mortality for comparison. To verify and revise the rebleeding risk score and death risk score that the investigators constructed earlier.The data were statistical processed by a professional statistician. The establishment of an acute upper gastrointestinal bleeding rebleeding and death risk scoring system for patients with liver cirrhosis can help distinguish patients with high or low risk of rebleeding or death to determine the patient's treatment needs.

Primary angle closure diseases (PACD) are commonly seen in Asia. In clinical practice, gonioscopy is the gold standard for angle width classification in PACD patietns. However, gonioscopy is a contact examination and needs a long learning curve. Anterior segment optical coherence tomography (AS-OCT) is a non-contact test which can obtain three dimensional images of the anterior segment within seconds. Therefore, the investigators designed the study to verify if AS-OCT based deep learning algorithm is able to detect the PACD subjects diagnosed by gonioscopy.

The need for and timing of booster doses of meningococcal vaccines in People Living with HIV (PLWHIV) is currently unknown. As such it is impossible for clinicians to recommend booster doses or to know if and when these might be necessary.We propose to follow up a group of participants from the Propositive study who received two doses of both MenB (Bexsero) and MenACWY (Menveo). This was a group of PLWHIV between the ages 18-45 years. We propose following up these participants at 18 and 30 months post completion of two doses of vaccine and investigating their immunological response.

This study is a prospective, multicenter, observational study on metastatic, operable colorectal cancer to evaluate the proof of concept of the cfDNA analysis for the early detection of recurrences

Endotracheal tube is a commonly used for general anesthesia in head and neck surgery. It is necessary to place the endotracheal tube in the trachea of the patient and then inflate the cuff with air. This is because the air-inflated cuff contacts the inner wall of the patient's trachea to deliver oxygen through the tube. If the cuff does not inflate, oxygen will leak through the space between the cuff and the patient's trachea. In addition, the risk of pneumonia increases. Therefore, after placing the endotracheal tube in the patient's trachea, the cuff is immediately inflated with air. However, when the cuff is inflated using an excess of air, the cuff may pressurize the mucous membrane of the tracheal wall and cause ischemia. Pressure in the over-inflated cuff was also found to be associated with post-operative sore throat, vocal cord paralysis, and nerve damage. Therefore, appropriate amount of air should be used to inflate the cuff into the air and adjust the pressure within the cuff to be within the range of 20-30 cmH2O. The common method to inflate the endotracheal tube cuff is palpation method. However, the palpation of the cuff is not accurate because of the different size between the pilot balloon and the cuff. Thus, the investigators hypothesized that the different size of the tube will affect the accuracy of the palpation method.

A Survey for Attitude and Awareness about radiography, radiographic equipment and radiation protection among dentists in Egypt

Work-related musculoskeletal disorders (WMSD) are a major public health problem both in France and internationally. Our clinical research project focuses on WMSD of the shoulder (WMSD-S), which account for 32% and 23% of these disorders in France and Europe, respectively. In order to prevent WMSD-S, the assessment and rehabilitation of workers' physical and functional capacities (PFC) (e.g. joint amplitude) may complement current interventions (e.g. ergonomics) in a novel manner. As a result, the objectives of this project would be to conduct a cohort study assessing the PFC of caregivers with WMSD-S compared to those of healthy subjects and a randomised, controlled, single-blind, multicentre clinical study assessing the relevance of a rehabilitation program for caregivers with WMSD-S working in a hospital setting. This project would foster the promotion of evidence-based physiotherapy and lead to the development of a interdisciplinary research team dedicated to rehabilitation.

Thyroid nodules are a common presentation in the clinic, with an increasing incidence, especially in women. Their clinical significance is mainly related to excluding malignancy (4.0 to 6.5% of all thyroid nodules).
