Multicenter Study on Physician-Modified Endografts for Thoracoabdominal and Complex Abdominal Aortic Aneurysm Repair.

Background: Physician modified endografts (PMEGs) have been widely used in the treatment of complex abdominal aortic aneurysm and thoracoabdominal aortic aneurysm, however, previous data are limited to small single center studies and robust data on safety and effectiveness of PMEGs are lacking. We aimed to perform an international multicenter study analyzing the outcomes of PMEGs in complex abdominal aortic aneurysms and thoracoabdominal aortic aneurysms.

Methods: An international multicenter single-arm cohort study was performed analyzing the outcomes of PMEGs in the treatment of elective, symptomatic, and ruptured complex abdominal aortic aneurysms and thoracoabdominal aortic aneurysms.

The association of body composition phenotypes before chemotherapy with epithelial ovarian cancer mortality.

Background: The association of body composition with epithelial ovarian carcinoma (EOC) mortality is poorly understood. To date, evidence suggests that high adiposity is associated with decreased mortality (an obesity paradox), but the impact of muscle on this association has not been investigated. Herein, we define associations of muscle and adiposity joint-exposure body composition phenotypes with EOC mortality.

Insertable cardiac monitoring results in higher rates of atrial fibrillation diagnosis and oral anticoagulation prescription after ischaemic stroke.

Aims: After an ischaemic stroke, atrial fibrillation (AF) detection allows for improved secondary prevention strategies. This study aimed to compare AF detection and oral anticoagulant (OAC) initiation in patients with an insertable cardiac monitor (ICM) vs. external cardiac monitor (ECM) after ischaemic stroke.

Sex-Dependent Transcriptional Changes in Response to Stress in Patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Pilot Project.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, multi-symptom illness characterized by debilitating fatigue and post-exertional malaise (PEM). Numerous studies have reported sex differences at the epidemiological, cellular, and molecular levels between male and female ME/CFS patients. To gain further insight into these sex-dependent changes, we evaluated differential gene expression by RNA-sequencing (RNA-Seq) in 33 ME/CFS patients (20 female, 13 male) and 34 matched healthy controls (20 female and 14 male) before, during, and after an exercise challenge intended to provoke PEM.

Mild-to-Moderate Kidney Dysfunction and Cardiovascular Disease: Observational and Mendelian Randomization Analyses.

Background: End-stage renal disease is associated with a high risk of cardiovascular events. It is unknown, however, whether mild-to-moderate kidney dysfunction is causally related to coronary heart disease (CHD) and stroke.

Methods: Observational analyses were conducted using individual-level data from 4 population data sources (Emerging Risk Factors Collaboration, EPIC-CVD [European Prospective Investigation into Cancer and Nutrition-Cardiovascular Disease Study], Million Veteran Program, and UK Biobank), comprising 648 135 participants with no history of cardiovascular disease or diabetes at baseline, yielding 42 858 and 15 693 incident CHD and stroke events, respectively, during 6.

Prospective validation and application of the Trauma-Specific Frailty Index: Results of an American Association for the Surgery of Trauma multi-institutional observational trial.

Background: The frailty index is a known predictor of adverse outcomes in geriatric patients. Trauma-Specific Frailty Index (TSFI) was created and validated at a single center to accurately identify frailty and reliably predict worse outcomes among geriatric trauma patients. This study aims to prospectively validate the TSFI in a multi-institutional cohort of geriatric trauma patients.

Primary Care Wound Clinics: A Qualitative Descriptive Study of Patient Experiences in Community Pharmacies.

The expansion of primary care wound services serves to alleviate secondary and tertiary care utilization. However, patient satisfaction is required to ensure service uptake. In recent years, various community pharmacies in Australia have begun to offer dedicated wound clinics; however, evaluations of patient experiences have yet to be conducted.

Developing a National Trauma Research Action Plan: Results from the geriatric research gap Delphi survey.

Background: Treating older trauma patients requires a focus on the confluence of age-related physiological changes and the impact of the injury itself. Therefore, the primary way to improve the care of geriatric trauma patients is through the development of universal, systematic multidisciplinary research. To achieve this, the Coalition for National Trauma Research has developed the National Trauma Research Action Plan that has generated a comprehensive research agenda spanning the continuum of geriatric trauma care from prehospital to rehabilitation.

Clinical characteristics, risk factors and outcomes in patients with severe COVID-19 registered in the International Severe Acute Respiratory and Emerging Infection Consortium WHO clinical characterisation protocol: a prospective, multinational, multicentre, observational study.

Due to the large number of patients with severe coronavirus disease 2019 (COVID-19), many were treated outside the traditional walls of the intensive care unit (ICU), and in many cases, by personnel who were not trained in critical care. The clinical characteristics and the relative impact of caring for severe COVID-19 patients outside the ICU is unknown. This was a multinational, multicentre, prospective cohort study embedded in the International Severe Acute Respiratory and Emerging Infection Consortium World Health Organization COVID-19 platform.

Outcomes of Primary Rhegmatogenous Retinal Detachment Repair in Eyes With Preoperative Grade B or C Proliferative Vitreoretinopathy.

Purpose: This work evaluates the anatomic and functional outcomes of primary rhegmatogenous retinal detachments (RRDs) with preoperative grade B and C proliferative vitreoretinopathy (PVR) vs eyes without PVR.

Methods: As a multi-institutional, interventional, retrospective study of all patients undergoing primary RRD surgical procedures from January 1, 2015, through December 31, 2015, this study evaluated the visual acuity (VA) outcomes and single-surgery anatomic success rates (SSAS) of patients with primary grade B and C PVR at the time of RRD repair.

Results: A total of 2486 eyes underwent primary RD surgery during the study period, of which 153 eyes (6.

The acute inflammatory response after trauma is heightened by frailty: A prospective evaluation of inflammatory and endocrine system alterations in frailty.

Background: Frailty is a geriatric syndrome characterized by decreased physiological reserves, increased inflammation, and decreased anabolic-endocrine response. The biomarkers associated with frailty are poorly understood in trauma. The aim of this study was to analyze the association between frailty and immune: IL-1β, IL-6, IL-2Rα, tumor necrosis factor (TNF)-α, and endocrine biomarkers: insulin-like growth factor-1 and growth hormone in trauma patients.

Safety and efficacy of brain injury guidelines at a Level III trauma center.

Background: Patients with mild to moderate traumatic brain injury (TBI) are often primarily managed by emergency medicine and trauma/acute care physicians. The Brain Injury Guidelines (BIG) were developed at an American College of Surgeons-accredited Level 1 trauma center to triage mild to moderate TBI patients and help identify patients who warrant neurosurgical consultation. The BIG have not been validated at a Level III trauma center.

Effect of Xenon Anesthesia Compared to Sevoflurane and Total Intravenous Anesthesia for Coronary Artery Bypass Graft Surgery on Postoperative Cardiac Troponin Release: An International, Multicenter, Phase 3, Single-blinded, Randomized Noninferiority Trial.

Background: Ischemic myocardial damage accompanying coronary artery bypass graft surgery remains a clinical challenge. We investigated whether xenon anesthesia could limit myocardial damage in coronary artery bypass graft surgery patients, as has been reported for animal ischemia models.

Methods: In 17 university hospitals in France, Germany, Italy, and The Netherlands, low-risk elective, on-pump coronary artery bypass graft surgery patients were randomized to receive xenon, sevoflurane, or propofol-based total intravenous anesthesia for anesthesia maintenance.

Cervical spinal clearance: A prospective Western Trauma Association Multi-institutional Trial.

Background: For blunt trauma patients who have failed the NEXUS (National Emergency X-Radiography Utilization Study) low-risk criteria, the adequacy of computed tomography (CT) as the definitive imaging modality for clearance remains controversial. The purpose of this study was to prospectively evaluate the accuracy of CT for the detection of clinically significant cervical spine (C-spine) injury.

Methods: This was a prospective multicenter observational study (September 2013 to March 2015) at 18 North American trauma centers.

ACSL1 Is Associated With Fetal Programming of Insulin Sensitivity and Cellular Lipid Content.

Individuals who are born small for gestational age (SGA) have a risk to develop various metabolic diseases during their life course. The biological memory of the prenatal state of growth restricted individuals may be reflected in epigenetic alterations in stem cell populations. Mesenchymal stem cells (MSCs) from the Wharton's jelly of umbilical cord tissue are multipotent, and we generated primary umbilical cord MSC isolates from SGA and normal neonates, which were subsequently differentiated into adipocytes.

Acceleration of diabetic retinopathy in pregnancy: a case report.

Aims: Diabetic retinopathy can deteriorate during pregnancy. This usually manifests itself as an increase in the number of background retinopathy lesions, notably the appearance of new cotton wool spots, predominantly during the first trimester. The changes are usually attributed to the rapid attainment of tight glycaemic control during pregnancy.

Phosphorylation of the inositol trisphosphate receptor in isolated rat hepatocytes.

The inositol trisphosphate receptor (IP3R) in brain has been shown to be a substrate for several different protein kinases in vitro. We have studied the phosphorylation of the IP3R in intact cells by using isolated hepatocytes and an antibody to immunoprecipitate the receptor protein from detergent extracts. Stimulation of 32P-labeled hepatocytes with glucagon or N6,2'-O-dibutyryladenosine 3',5'-cyclic monophosphate (db-cAMP) markedly increased phosphorylation of the IP3R.

Effect of trifluoperazine on the stimulation by Ca2+-dependent hormones of gluconeogenesis from glutamine in isolated hepatocytes.

In continuation of our previous studies we have investigated some aspects of the hormonal control of glutamine metabolism in isolated rat hepatocytes. (1)Catecholamines, angiotensin II and vasopressin stimulate gluconeogenesis from glutamine more than 2-fold. These effects require the presence of Ca2+ in the incubation medium.
