Data from: Neurological and neuroimaging findings in COVID-19 patients: a retrospective multicenter study
Objective To describe neuroimaging findings and to report the epidemiological and clinical characteristics of COVID-19 patients with neurological manifestations. Methods In this retrospective multicenter study (10 Hospitals), we included 64 confirmed COVID-19 patients with neurologic manifestations who underwent a brain MRI. Results The cohort included 43 men (67%), 21 women (33%), and the median age was 66 years (range: 20-92). 36 (56%) brain MRIs were considered abnormal, possibly related to SARS-CoV-2. Ischemic strokes (27%), leptomeningeal enhancements (17%), and encephalitis (13%) were the most frequent neuroimaging findings. Confusion (53%) was the most common neurological manifestation, following by impaired consciousness (39%), presence of clinical signs of corticospinal tract involvement (31%), agitation (31%), and headache (16%). The profile of patients experiencing ischemic stroke was different from the other patients with abnormal brain imaging since the former had less frequently acute respiratory distress syndrome (p=0·006) and more frequently corticospinal tract signs (p=0·02). Patients with encephalitis were younger (p=0·007), whereas agitation was more frequent for patients with leptomeningeal enhancements (p=0·009). Conclusions COVID-19 patients may develop a wide range of neurological symptoms, which can be associated with severe and fatal complications, such as ischemic stroke or encephalitis. Concerning the meningoencephalitis involvement, even if a direct effect of the virus cannot be excluded, the pathophysiology rather seems to involve an immune and/or inflammatory process given the presence of signs of inflammation in both cerebrospinal fluid and neuroimaging but the lack of virus in cerebrospinal fluid.

The benefit of kidney transplantation versus remaining on the waitlist depends on patients' baseline comorbidities: a retrospective study
<p>Background:<b> </b>Patients with end-stage renal disease present comorbidities that increase mortality risk on the waitlist and after kidney transplantation. This study aimed to determine the impact of baseline comorbidities on the risk of death after kidney transplantation compared to remaining on the waitlist.</p> <p>Methods: Records of waitlisted patients were retrospectively analyzed. Multivariable time-dependent Cox-regression model was used to determine the initial and the lowest relative hazard-risk of death (HRD) after exposure to kidney transplantation.</p> <p>Results: 1692 patients were included in the study. Patients without comorbidities had the relative HRD 3-fold higher, immediately after kidney transplantation, but it reduced progressively, reaching equality to waitlist at 75 days and a HRD of 0.28 thereafter (p<0.001). Patients with Diabetes and coronary artery disease had an initial relative HRD of 2.41 (p=0.009) and 2.68 (p=0.009) and matched to the waitlist at 175 and 200 days, respectively. Patients with peripheral vascular disease, had an initial relative HRD 3.6-fold in the first 240 days (p=0.008) and patients with congestive heart failure a relative HRD of 7.47 (p=0.07). Both declined rapidly, reaching equality at 110 days. Finally, all comorbidities, except cerebrovascular disease, presented lower HRD on long-term follow-up.</p> <p>Conclusions: This study shows that the time and the range of relative HRD between kidney transplantation and waitlist varies depending upon the patients´ baseline comorbidities.</p>
Data from: Epidemiology of injuries in elite taekwondo athletes: two Olympic periods cross-sectional retrospective study
Objective: Taekwondo injuries differ according to the characteristics of the athletes and the competition. This analytical cross-sectional retrospective cohort study aimed to describe reported taekwondo injuries and to determine the prevalence, characteristics and possible risk factors for injuries sustained by athletes of the Spanish national team. In addition, we compared each identified risk factor—age, weight category, annual quarter, injury timing and competition difficulty level—with its relation to injury location and type. Settings: Injury occurrences in taekwondo athletes of the Spanish national team during two Olympic periods at the High Performance Centre in Barcelona were analysed. Participants: 48 taekwondo athletes (22 male, 26 female; age range 15–31 years) were studied; 1678 injury episodes occurred. Inclusion criteria were: (1) having trained with the national taekwondo group for a minimum of one sports season; (2) being a member of the Spanish national team. Results: Independently of sex or Olympic period, the anatomical sites with most injury episodes were knee (21.3%), foot (17.0%), ankle (12.2%), thigh (11.4%) and lower leg (8.8%). Contusions (29.3%) and cartilage (17.6%) and joint (15.7%) injuries were the prevalent types of injury. Chronological age, weight category and annual quarter can be considered risk factors for sustaining injuries in male and female elite taekwondists according to their location and type (p≤0.001). Conclusions: This study provides epidemiological information that will help to inform future injury surveillance studies and the development of prevention strategies and recommendations to reduce the number of injuries in taekwondo competition.
Data from: Clinical characteristics and prognosis of drug-associated acute respiratory distress syndrome compared with non-drug-associated acute respiratory distress syndrome: a single-centre retrospective study in Japan
Objectives To report the clinical features and prognosis of drug-associatedacute respiratory distress syndrome (ARDS). Design A retrospective analysis of data collected during a prospective cohort study. Setting Intensive care unit in a teaching hospital. Participants A total of 197 Japanese patients with ARDS diagnosed by the Berlin definition who were admitted to the Division of Respiratory Medicine from October 2004 to December 2015 were enrolled in the study and were classified as two groups according to their causes: a drug-associated ARDS group (n=27) and a non-drug-associated ARDS group (n=170). Primary outcome measure is 28-day mortality, and the secondaryoutcome measure is ventilator-free days. Results The Acute Physiology and Chronic Health Evaluation II scores were significantly lower in the drug-associated ARDS group than in the non-drug-associated ARDS group (median (IQR): 18.0 (16.5–21.0) vs 23.0 (18.0–26.0), p<0.001), and the arterial oxygen tension/fractional inspired oxygen ratio was higher (148.0 (114.1–177.5) vs 101.0 (71.5–134.0), p=0.003). In the drug-associated ARDS group, although high-resolution CT scores indicative of the extent of fibroproliferation (301.6 (244.1–339.8) vs 208.3 (183.4–271.6), p<0.001), serum lactate dehydrogenase levels (477 (365–585) vs 322 (246–434), p=0.003) and the McCabe scores (score 1/2/3, n (%): 20 (74)/4 (15)/3 (11)vs154 (91)/7 (4)/9 (5), p=0.04) were significantly higher, ventilator weaning was earlier (p<0.001) and 28-day mortality was better (p=0.043). After adjusting for potentially confounding covariates, drug-associated ARDS group was associated with lower 28-day mortality (adjusted HR (HR) 0.275; 95% CI 0.106 to 0.711; p=0.008). Conclusions Although more severe lung damage with fibroproliferation was observed in patients with drug-associated ARDS, ventilator weaning was earlier, and their prognosis was better than the others. Further well-designed prospective studies are needed.
Data from: Proportion of women presenters at medical grand rounds at major academic centres in Canada: a retrospective observational study
Objective: To assess the proportion of women who presented research or medical grand rounds at five major academic hospitals in Canada. Design: A cross sectional study. Setting: Five major university–affiliated hospitals in Toronto and Calgary. Results: Overall, at all sites and types of academic rounds, there were an average of 17% fewer women presenting than men (p < 0.001). There were an average of 32% and 21% more men presenting at the city wide grand rounds in City A and B respectively (p < 0.001, p = 0.002). There were more male speakers at 4 out of 5 types of rounds. The proportion of women presenting on average was proportional to the Canadian workforce, but on average, below the proportion of female residents and medical students (median ratio 1.1, 0.7 and 0.8 respectively). Conclusion: Our study demonstrated a lower proportion of females in an important outlet for academic recognition and role modeling. This provides a possible contributing factor to the under representation of women in academic medicine, and an area that can be systematically targeted to promote equity.
Data from: Perfusion index in newborns during critical congenital heart disease screening at 24 hours in healthy newborns: retrospective observational study from the United States
Objective: To describe the distribution of Perfusion Index (PI) in asymptomatic newborns at 24 hours of life when screening for Critical Congenital Heart Disease (CCHD) using an automated data selection method. Design: This is a retrospective observational study. Setting: Newborn nursery in a California public hospital with 3500 to 4000 deliveries annually. Methods: We developed an automated program to select the PI values from CCHD screens. Included were term and late preterm infants who were screened for CCHD from November 2013 to January 2014 and from May 2015 to July 2015. PI measurements were downloaded every 2 seconds from the pulse oximeter and median PI were calculated for each oxygen saturation screen in our cohort. Results: We included data from 2768 oxygen saturation screens. Each screen had a median of 29 data points (interquartile range 17 to 49). The median PI in our study cohort was 1.8 (95% confidence interval 1.8 to 1.9) with interquartile range 1.2 to 2.7. The median pre-ductal PI was significantly higher than the median post-ductal (1.9 vs. 1.8, p = 0.03) although this difference may not be clinically significant. Conclusion: Using an automated data selection method, the median PI in asymptomatic newborns at 24 hours of life is 1.8 with a narrow interquartile range of 1.2 to 2.7. This automated data selection method may improve accuracy and precision compared to manual data collection method. Further studies are needed to establish external validity of this automated data selection method and its clinical application for CCHD screening.
