Increased Risk

Patients with type 2 diabetes mellitus (T2DM) are at increased risk of severe COVID-19 outcomes possibly due to dysregulated inflammatory responses. Glucose-regulating medications such as glucagon-like peptide-1 receptor (GLP-1R) agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, and pioglitazone are known to have anti-inflammatory effects that may improve outcomes in patients with SARS-CoV-2 infection. In a multinational retrospective cohort study, we used the TriNetX COVID-19 Research Network of 56 large healthcare organizations to examine these medications in relation to the incidence of hospital admissions, respiratory complications, and mortality within 28 days following a COVID-19 diagnosis. After matching for age, sex, race, ethnicity, body mass index, and significant comorbidities, use of GLP-1R agonists and/or pioglitazone was associated with significant reductions in hospital admissions (GLP-1R: 15.7% vs 23.5%; RR, 0.67 [95% CI, 0.57-0.79]; <i>P</i> <.001; pioglitazone: 20.0% vs 28.2%; RR, 0.71 [95% CI, 0.54-0.93]; <i>P</i> =.01). Use of GLP-1R agonists was also associated with reductions in respiratory complications (15.3% vs 24.9%; RR, 0.62 [95% CI, 0.52-0.73]; <i>P</i> <.001) and incidence of mortality (1.9% vs 3.3%; RR, 0.58 [95% CI, 0.35-0.97]; <i>P</i> =.04). Use of DPP-4 inhibitors was associated with a reduction in respiratory complications (24.0% vs 29.2%; RR, 0.82 [95% CI, 0.74-0.90]; <i>P</i> <.001), and continued use of DPP-4 inhibitors after hospitalization was associated with a decrease in mortality compared with those who discontinued use (9% vs 19%; RR, 0.45 [95% CI, 0.28-0.72]; <i>P</i> <.001). In conclusion, use of glucose-regulating medications such as GLP-1R agonists, DPP-4 inhibitors, or pioglitazone may improve outcomes for COVID-19 patients with T2DM; randomized clinical trials are needed to further investigate this possibility.

Abstract Background International guidelines recommend that children older than 2 years of age consume reduced fat (0.1-2%) instead of whole cow’s milk (3.25% fat) to prevent childhood obesity, but these guidelines are consensus-based and have a low GRADE level of evidence. Objectives The primary objective of this study was to evaluate the longitudinal relationship between cow’s milk fat (0.1-3.25%) intake and Body Mass Index z-score (zBMI) in children aged 9 months to 8 years. The secondary objective was to determine the relationship between cow’s milk fat intake and odds of overweight (zBMI &gt;1) and obesity (zBMI &gt; 2). Design/Methods A prospective cohort study of children 9 months to 8 years of age was conducted through the TARGet Kids! primary care research network. The primary exposure was cow’s milk fat consumption (skim (0.1%), 1%, 2%, or whole [3.25%]), measured by parental report. The primary outcome was zBMI, an age and sex adjusted measure of child adiposity. Height and weight were measured by trained research assistants and zBMI was determined according to the WHO growth standards. A linear mixed effects model and logistic generalized estimating equations were used to determine the longitudinal association between cow’s milk fat intake and child zBMI. Results Among children aged 9 months to 8 years of age (N= 7467), each 1% increase in cow’s milk fat consumed was associated with a 0.05 lower zBMI score (95% CI -0.07 to -0.03, p&lt; 0.0001). Compared to children who consumed reduced fat (0.1-2%) cow’s milk, there was evidence that children who consumed whole cow’s milk had 16% lower odds of overweight (OR=0.84, 95% CI 0.77 to 0.91), p&lt; 0.0001) and 18% lower odds of obesity (OR= 0.82, 95% CI 0.68 to 1.00, p= 0.047). Conclusion Guidelines for reduced fat instead of whole cow’s milk during childhood may not be effective in preventing overweight or obesity. Randomized controlled trial data is needed to understand which cow’s milk fat optimizes child growth, development and nutrition.

ObjectiveTo investigate the characteristics of persistent pulmonary hypertension of the newborn (PPHN) in extremely preterm infants and its impact on neurodevelopmental outcomes at 3 years of age.DesignA retrospective multicentre cohort study.Settings202 tertiary perinatal centres registered in the Neonatal Research Network of Japan (NRNJ).PatientsInfants born at <28 weeks of gestational age (GA), between 2003 and 2012, were extracted from tertiary perinatal centres participating in NRNJ.Main outcome measuresDemographic characteristics, morbidity, interventions and mortality were compared for infants with and without PPHN. Multivariable logistic analysis was performed to evaluate the impact of PPHN on long-term neurodevelopmental outcomes (the prevalence rate of cerebral palsy, need for home oxygen therapy, and visual, hearing and cognitive impairment) at 3 years of age.ResultsThe prevalence of PPHN among the 12 954 extremely preterm infants enrolled was 8.1% (95% CI 7.7% to 8.6%), with the trend increasing annually, and a higher proportion as GA decreased: 18.5% (range, 15.2% to 22.4%) for infants born at 22 weeks compared with 4.4% (range, 3.8% to 5.2%) for those born at 27 weeks. Clinical chorioamnionitis and premature rupture of membranes were associated with PPHN. On multivariate analysis of the data from 5923 infants followed up for 3 years, PPHN was a significant independent risk factor for visual impairment (adjusted OR, 1.42, 95% CI 1.03 to 1.97).ConclusionsThe prevalence of PPHN in extremely preterm infants has been increasing over the past decade in Japan. Clinicians should be aware of visual impairments as a neurodevelopmental abnormality among infants with PPHN.

Chronic Postoperative Inguinal Pain

AbstractPurposeRecent comprehensive guidelines have been published on the management of inguinal hernia. Contrary to other European countries, no Portuguese hernia registry exists. This represents an opportunity to assess outcomes of hernia surgery in the Portuguese population. The primary aim is to define the prevalence of chronic pain after elective inguinal hernia repair. The secondary aims are to identify risk factors for chronic pain after elective inguinal hernia repair, to characterise the management of elective inguinal hernia in public Portuguese hospitals.MethodsProspective national cohort study of patients submitted to elective inguinal hernia repair. The primary outcome is the prevalence of chronic postoperative inguinal pain, according to the EuraHS QoL questionnaire at 3 months postoperatively. The study will be delivered in all Portuguese regions through a collaborative research network. Four 2-week inclusion periods will be open for recruitment. A site-specific questionnaire will capture procedure volume and logistical facilities for hernia surgery.ConclusionThis protocol describes the methodology of a prospective cohort study on the elective management of inguinal hernia. It discusses key challenges and describes how the results will impact future investigation. The study will be conducted across a nationwide collaborative research network, with prospective quality assurance and data validation strategies. It will provide the basis for a more accurate prediction of chronic postoperative inguinal pain and the research on adequate patient selection strategies for surgery and therapeutic strategies for postoperative pain.

Minor Head Trauma

Abstract Background Managing children with minor head trauma remains challenging for physicians who evaluate for the need for computed tomography (CT) imaging for clinically important traumatic brain injury (ciTBI) identification. The Pediatric Emergency Care Applied Research Network (PECARN) prediction rules were adopted in our pediatric emergency department (PED) in December 2013 to identify children at low risk for ciTBI. This study aimed to evaluate this implementation’s impact on CT rates and clinical outcomes. Methods Retrospective cohort study on pediatric patients with head trauma presenting to the PED of the American University of Beirut Medical Center in Lebanon. Participants were divided into pre- (December 2012 to 2013) and post-PECARN (January 2014 to December 2016) groups. Patients were further divided into <2 and ≥2 years and stratified into groups of low, intermediate and high risk for ciTBI. Bivariate analysis was conducted to determine differences between both groups. Results We included 1362 children of which 425 (31.2%) presented pre- and 937 (68.8%) presented post-PECARN rules implementation with 1090 (80.0%) of low, 214 (15.7%) of intermediate and 58 (4.3%) of high risk for ciTBI. CTs were ordered on 92 (21.6%) pre- versus 174 (18.6%) patients post-PECARN (p=0.18). Among patients <2 years, CT rates significantly decreased from 25.2% to 16.5% post-PECARN (p=0.03), and dropped in all risk groups but only significantly for low risk patients from 20.7% to 11.4% (p=0.02). There was no significant decrease in CT rates in patients ≥2 years. There was no increase in bounce-backs numbers, nor in admission rates or positive CT findings among bounce-backs. Conclusions PECARN rules implementation reduced CT rates, most significantly among patients <2 years at low risk for ciTBI. The implementation did not increase the number of missed ciTBI.
