Comparisons of these collective data with histopathological evaluation of a swine model of concussion demonstrated a notably similar pattern of axonal damage adjacent to the gray-white interface. The results suggest that the tissue property mismatch at the gray-white matter interface places axons crossing this region at greater risk of mechanical damage during brain tissue deformation from traumatic brain injury.Oocyte activation, the dynamic transformation of an oocyte into an embryo, is largely driven by Ca2+ oscillations that vary in duration and amplitude across species. Previous studies have analysed intraoocyte Ca2+ oscillations in the absence of the oocyte's supporting cumulus cells. Therefore, it is unknown whether cumulus cells also produce an ionic signal that reflects fertilisation success. Time-lapse confocal microscopy and image analysis on abattoir-derived cattle cumulus-oocyte complexes coincubated with spermatozoa revealed a distinct discharge of fluorescence from the cumulus vestment. This study demonstrated that this Ca2+ fluorescence discharge was an artefact induced by the imaging procedure independently of oocyte activation success. The fluorescence discharge was a direct result of cumulus cell membrane integrity loss, and future studies should consider the long-term effect of fluorescent labels on cells in time-lapse imaging. However, this study also demonstrated that the distinctive pattern of a coordinated fluorescence discharge was associated with both the presence of spermatozoa and subsequent embryo development to the morula stage, which was affected by Ca2+ chelation and a reduction in the active efflux of the fluorophore. This indicates that the cumulus vestment may have a relationship with oocyte activation at and beyond fertilisation that requires further investigation.This case-controlled study determined the utility of the READMIT index to identify the risk for 30-day readmission of patients discharged from an urban community hospital psychiatric inpatient unit. Data was collected from 118 matched patient pairs from 2017 to 2018. Findings demonstrated the READMIT index did not effectively discriminate those patients who were likely to readmit within 30 days. However, the following factors were associated with likelihood of 30-day readmission the inability to care for self, number of lifetime readmissions, the comorbidity of liver disease, as well as a history of substance abuse.

Pancreatic injuries are rare. Reports are lacking from defined European populations covering all ages and genders and in areas with a low prevalence of penetrating trauma. We aimed to review pancreatic injuries identified within a defined population.

Observational cohort study from a prospectively maintained trauma registry and all patients coded for a pancreatic injury between January 1, 2004 and December 31, 2018.

A total of 14 patients with pancreatic injury were identified over a 15-year time period. Pancreatic injuries represented 0,19% (14/7207) of all trauma patients and 3,1% (14/454) of patients with documented abdominal injuries. Nine patients 64% (9/14) were children, representing 1% (9/869) of all injured children in the registry and 11,4% (9/79) of children with documented abdominal injuries. Median age was 10,5 years (range 3-58). Ten were male (71%) and 86% (12/14) suffered blunt trauma. Median AAST-OIS was 2 (1-4). Single organ injury occurred in 43% (6/14). Concomitant liver injury was the most frequent associated intra-abdominal injury found in 29% (4/14). Four patients (29%) had associated injuries in other body regions, all thoracic injuries. Median ISS was 9,5 (4-41).Operative management was needed for four of the pancreatic injuries, one spleen-preserving distal pancreatectomy, one spleen-sacrificing distal pancreatectomy and two peripancreatic drainages. One patient died within 30-days, but the death was unrelated to the pancreatic injury.

Incidence of pancreatic injuries is low, even among trauma patients with documented abdominal injuries. Most pancreatic injuries occurred in children. Injuries requiring surgery was rare.

Canada reported its first case of COVID-19 on 25th January 2020. By March 2020 the virus had spread within Canadian communities reaching the most frail and vulnerable elderly population in long-term care facilities. The majority of cases were reported in the provinces of Quebec, Ontario, Alberta and British Columbia and the highest mortality was seen among individuals aged 65 years or older. Canada has the highest prevalence and incidence rates of several chronic inflammatory diseases, such as multiple sclerosis, inflammatory bowel disease and Parkinson's disease. Many elderly Canadians also live with comorbid medical illnesses, such as hypertension, diabetes, cardiovascular disease and chronic lung disease and are more likely to suffer from severe COVID-19 with a poor prognosis. It is becoming increasingly evident that underlying inflammatory disease contributes to SARS-CoV-2 pathogenesis. Here, we review the mechanisms of SARS-CoV-2 infection and the host inflammatory responses that lead to resolution or progression to severe COVID-19 disease. Furthermore, we discuss the landscape of COVID-19 therapeutics that are currently in development in Canada.Rationale Minority sexual identity appears to confer asthma risks. Although associations between inhaled substances and asthma are established, these have not been examined among sexual minority youths. Given sexual minority adolescents' disproportionately high rates of substance use, research is needed to fill this important gap.Objectives Using a representative sample of adolescents from the United States, we 1) examined associations among asthma, sexual identity, and inhaled substance use and tested 2a) whether sexual identity moderates relationships between asthma and inhaled substance use and 2b) whether inhaled substance use mediates associations between sexual identity and asthma.Methods Data are from the 2015 and 2017 Youth Risk Behavior Surveillance Survey. Adolescents (n = 30,113) reported if they were ever diagnosed with asthma, current use of cigarettes, cigars and/or cigarillos, marijuana, and electronic vapor products and if they ever used inhalants or synthetic marijuana. We used logistic regression to examine associations between asthma, sexual identity, and inhaled substance use controlling for age, race or ethnicity, and body mass index percentile, stratified by sex.
