Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery

Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery.A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a c…

Prospective evaluation of current asthma control using ACQ and ACT compared with GINA criteria

Background The goal of asthma treatment is to achieve and maintain current best control and reduce future risk of exacerbations and long-term morbidity. Objective To prospectively compare current asthma control as defined by ACQ (asthma control questionnaire) and ACT (asthma control test) criteria with the GINA (Global Initiative for Asthma) classification in treated patients in a real-life setting. Methods In 150 adult patients (48% male, age 46.3 ± 14.4 years., forced expiratory volume in 1 second [FEV 1 ], 2.3 ± 0.9 L or 78.5 ± 21.8% pred.), asthma control was evaluated using the GINA classification as the "true" and ACQ-7, ACQ-5, and ACT as "predictor" criteria. The relationship between…

Safety of hospital discharge before return of bowel function after elective colorectal surgery

Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…

Effect of Intraoperative High Positive End-Expiratory Pressure (PEEP) with Recruitment Maneuvers vs Low PEEP on Postoperative Pulmonary Complications in Obese Patients: A Randomized Clinical Trial

Importance: An intraoperative higher level of positive end-expiratory positive pressure (PEEP) with alveolar recruitment maneuvers improves respiratory function in obese patients undergoing surgery, but the effect on clinical outcomes is uncertain. Objective: To determine whether a higher level of PEEP with alveolar recruitment maneuvers decreases postoperative pulmonary complications in obese patients undergoing surgery compared with a lower level of PEEP. Design, Setting, and Participants: Randomized clinical trial of 2013 adults with body mass indices of 35 or greater and substantial risk for postoperative pulmonary complications who were undergoing noncardiac, nonneurological surgery un…

Quantification Of Total Serum IgE In Patients With Asthma Using 3 Different Methods

Severe and uncontrolled adult asthma is associated with vitamin D insufficiency and deficiency

Background Vitamin D has effects on the innate and adaptive immune system. In asthmatic children low vitamin D levels are associated with poor asthma control, reduced lung function, increased medication intake, and exacerbations. Little is known about vitamin D in adult asthma patients or its association with asthma severity and control. Methods Clinical parameters of asthma control and 25-hydroxyvitamin D (25(OH)D) serum concentrations were evaluated in 280 adult asthma patients (mean ± SD: 45.0 ± 13.8 yrs., 40% male, FEV1 74.9 ± 23.4%, 55% severe, 51% uncontrolled). Results 25(OH)D concentrations in adult asthmatics were low (25.6 ±11.8 ng/ml) and vitamin D insufficiency or deficiency (vi…

Two-particle transverse momentum correlations in pp and p-Pb collisions at energies available at the CERN Large Hadron Collider

Two-particle transverse momentum differential correlators, recently measured in Pb--Pb collisions at energies available at the CERN Large Hadron Collider (LHC), provide an additional tool to gain insights into particle production mechanisms and infer transport properties, such as the ratio of shear viscosity to entropy density, of the medium created in Pb-Pb collisions. The longitudinal long-range correlations and the large azimuthal anisotropy measured at low transverse momenta in small collision systems, namely pp and p-Pb, at LHC energies resemble manifestations of collective behaviour. This suggests that locally equilibrated matter may be produced in these small collision systems, simil…

Vitamin D Insufficiency In Adult Asthma Is Associated With Asthma Severity And Control

Data in asthmatic children suggest that low vitamin D levels are associated with poor asthma control, reduced lung function, and increased medication intake. To investigate the role of vitamin D insufficiency in adult asthmatics 25-hydroxyvitamin D was measured in 280 adult patients with asthma (mean±SEM: 45.0±0.8 yrs., 40% male, FEV1 74.9±1.4%) and correlated with clinical parameters of asthma control. The majority of patients had severe asthma (n=155, 55%) and were uncontrolled (n=144, 51%). Serum levels of vitamin D were significantly related to asthma severity (mean±SEM: intermittent 31.1±3.2 ng/ml, mild 27.3±1.6 ng/ml, moderate 26.5±1.5, severe 24.0±0.9, p=0.046) and asthma control (co…
