A variety of policies and practices have been implemented to increase participation in the National School Breakfast Program (SBP) and the impact of these initiatives on SBP participation is not known. The purpose of this study was to determine whether new SBP policies and practices implemented in North Carolina were associated with an improvement in SBP participation. A mixed modeling approach was used to assess longitudinal patterns of change in district-level and school-level SBP participation rates between 2007 and 2015. Most of the policy initiatives implemented in NC were associated with an increase in participation either at the school or district level.

IMPORTANCE:It remains unknown whether in an asymptomatic community-based cohort magnetic resonance imaging (MRI) measures of plaque characteristics are independently associated with incident cardiovascular disease (CVD) events when adjusted for carotid artery (CA) wall thickness, a measure of plaque burden. OBJECTIVE:To assess associations of CA MRI plaque characteristics with incident CVD events. DESIGN, SETTING, AND PARTICIPANTS:The Atherosclerosis Risk in Communities (ARIC) study is a prospective epidemiologic study of the incidence of CVD in 15 792 adults of which 2066 women and men were enrolled in the ARIC Carotid MRI substudy. ARIC participants were enrolled from 1987 to 1989, and the substudy was conducted between January 2004 and December 2005. Analysis began January 2017 and ended August 2020. EXPOSURES:Incident CVD events during a median (interquartile range [IQR]) follow-up time of 10.5 (8.1-10.9) years were assessed. MAIN OUTCOMES AND MEASURES:Proportional hazards Cox analyses were performed to ascertain associations between MRI variables of CA plaque burden and plaque characteristics. RESULTS:Of 15 792 ARIC participants, 2066 were enrolled in the substudy, of whom 1256 (701 women [55.8%]) had complete data and were eligible for incident CVD analyses. Carotid artery plaques in participants with incident CVD events (172 [13.7%]) compared with those without (1084 [86.3%]) had a higher normalized wall index (median [IQR], 0.48 [0.36-0.62] vs 0.43 [0.34-0.55]; P = .001), maximum CA wall thickness (median [IQR], 2.22 [1.37-3.52] mm vs 1.96 [1.29-2.85] mm; P = .01), maximum CA stenosis (median [IQR], 5% [0%-22%] vs 0% [0%-13%]; P < .001), and when present, a larger lipid core volume (median [IQR], 0.05 [0.02-0.11] mL vs 0.03 [0.01-0.07] mL; P = .03), respectively. The presence of a lipid core was independently associated with incident CVD events when adjusted for traditional CVD risk factors and maximum CA wall thickness (hazard ratio, 2.48 [95% CI, 1.36-4.51]; P = .003), whereas the presence of calcification was not. The frequency of intraplaque hemorrhage presence in this population of individuals free of CVD at baseline who were not recruited for carotid stenosis was too small to draw any meaningful conclusions (intraplaque hemorrhage presence: 68 of 1256 participants [5.4%]). Carotid artery lumen area and maximum stenosis, which were overall low, were independently associated with incident CVD events when adjusted for traditional CVD risk factors, as anticipated. CONCLUSIONS AND RELEVANCE:The presence of a CA lipid core on MRI is associated with incident CVD events independent of maximum CA wall thickness in asymptomatic participants.

BACKGROUND:Aortic occlusion (AO) is utilized for patients in extremis, with resuscitative endovascular balloon occlusion of the aorta (REBOA) use increasing. Our objective was to examine changes in AO practices and outcomes over time. The primary outcome was the temporal variation in AO mortality, while secondary outcomes included changes in technique, utilization, and complications. STUDY DESIGN/METHODS:This study examined the AORTA registry over a 5-year period (2014-2018). AO outcomes and utilization were analyzed using year of procedure as an independent variable. A multivariable model adjusting for year of procedure, signs of life (SOL), SBP at AO initiation, operator level, timing of AO, and hemodynamic response to AO was created to analyze AO mortality. RESULTS:1458 AO were included. Mean age (39.1 ± 16.7) and Median ISS (34[25,49]) were comparable between REBOA and Open AO. Open AO patients were more likely: male (84% vs. 77%, p = 0.001), s/p penetrating trauma (61% vs. 19%, p < 0.001), and arrived without SOL (60% vs. 40%, p = 0.001). REBOA use increased significantly and adjusted mortality decreased 22%/year while open AO survival was unchanged. REBOA initiation SBP increased significantly over the study period (52.2 vs. 65, p = 0.04). Compared with patients undergoing AO with CPR, each decile increase in SBP improved survival 12% (AOR 1.12, adj p = 0.001). The use of 7F REBOA (2.9% to 54.8%) and Zone III deployment increased significantly (14.7% vs 40.6%), with Zone III placement having decreased associated mortality (AOR 0.33, adj p = 0.001). Overall REBOA complication rate was 4.5% and did not increase over time (p = 0.575). CONCLUSIONS:REBOA survival has increased significantly while open AO survival remained unchanged. This may be related to lower thresholds for REBOA insertion at higher blood pressures, increased operator experience and improved catheter technology leading to earlier deployment.

Research Findings: Evidence suggests that teachers are effective at improving the social and emotional readiness of low-income children. However, few measures are available to assess teachers"™ use of specific social-emotional practices within their classrooms. This paper compares an observational measure of teachers"™ social-emotional practices, the Adapted Teacher Style Rating Scale (TSRS), to an instrument of general classroom climate within a randomized control trial, including 307 Head Start classrooms across the country. Results confirmed the expected underlying three-factor structure of the Adapted-TSRS across mixed-age and 4-year-old only Head Start classrooms. The measure was found to have good internal consistency, reliability, and acceptable concurrent correlations with other previously validated observational measures of classroom climate. Policy or Practice: The results support the usefulness and added value of a more specific observational measure of teachers"™ social-emotional practices.

Dissemination of misinformation through social media is a major societal issue. Bladder cancer is the second most common urological cancer in the world, but there are limited data on the quality of bladder cancer information on social networks. Our objective was to characterize the quality of information and presence of misinformation about bladder cancer on YouTube, the most commonly used social media platform. We reviewed the first 150 YouTube videos about "bladder cancer" using two validated instruments for consumer health information and assessed the videos for the presence of misinformation. The videos had a median of 2288 views (range, 14-511 342), but the overall quality of information was moderate to poor in 67%, based on scores of 1-3 out of 5 on the validated DISCERN instrument. A moderate to high amount of misinformation was present in 21% of videos and reached 1 289 314 viewers. Commercial bias was apparent in 17% of videos, which reached 324 287 viewers. From a networking perspective, comments sections in the videos were sometimes used to request medical advice (20%), provide medical advice to others (9%), or give support (19%). In conclusion, YouTube is a widely used source of information and advice about bladder cancer, but much of the content is of poor quality. PATIENT SUMMARY: A large quantity of content about bladder cancer is available on YouTube. Unfortunately, much of the content is of moderate to poor quality and presents a risk of exposure to misinformation.

The clinical progression of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19) to critical illness is associated with an exaggerated immune response, leading to magnified inflammation termed the "cytokine storm." This response is thought to contribute to the pathogenicity of severe COVID-19. There is an initial weak interferon response and macrophage activation that results in delayed neutrophil recruitment leading to impeded viral clearance. This causes prolonged immune stimulation and the release of proinflammatory cytokines. Elevated inflammatory markers in COVID-19 (i.e., D-dimer, C-reactive protein, lactate dehydrogenase, ferritin, and interleukin-6) are reminiscent of "cytokine storm" seen in severe hyperinflammatory macrophage disorders. The dysfunctional immune response in COVID-19 also includes lymphopenia, reduced T-cells, reduced natural killer cell maturation, and unmitigated plasmablast proliferation causing aberrant immunoglobulin G levels. The progression to severe disease is accompanied by endotheliopathy, immunothrombosis, and hypercoagulability. Thus, both parts of the immune system-innate and adaptive-play a significant role in the cytokine storm, multiorgan dysfunction, and coagulopathy. This review highlights the importance of understanding the immunological mechanisms of COVID-19 as they inform the clinical presentation and advise potential therapeutic targets.

OBJECTIVE:To develop a 180-day readmission risk model for older adults with acute myocardial infarction (AMI) that considered a broad range of clinical, demographic and age-related functional domains. METHODS:We used data from ComprehenSIVe Evaluation of Risk in Older Adults with AMI (SILVER-AMI), a prospective cohort study that enrolled participants aged ≥75 years with AMI from 94 US hospitals. Participants underwent an in-hospital assessment of functional impairments, including cognition, vision, hearing and mobility. Clinical variables previously shown to be associated with readmission risk were also evaluated. The outcome was 180-day readmission. From an initial list of 72 variables, we used backward selection and Bayesian model averaging to derive a risk model (N=2004) that was subsequently internally validated (N=1002). RESULTS:Of the 3006 SILVER-AMI participants discharged alive, mean age was 81.5 years, 44.4% were women and 10.5% were non-white. Within 180 days, 1222 participants (40.7%) were readmitted. The final risk model included 10 variables: history of chronic obstructive pulmonary disease, history of heart failure, initial heart rate, first diastolic blood pressure, ischaemic ECG changes, initial haemoglobin, ejection fraction, length of stay, self-reported health status and functional mobility. Model discrimination was moderate (0.68 derivation cohort, 0.65 validation cohort), with good calibration. The predicted readmission rate (derivation cohort) was 23.0% in the lowest quintile and 65.4% in the highest quintile. CONCLUSIONS:Over 40% of participants in our sample experienced hospital readmission within 180 days of AMI. Our final readmission risk model included a broad range of characteristics, including functional mobility and self-reported health status, neither of which have been previously considered in 180-day risk models.

In this study, we sought to determine the burden and characteristics of orgasmic dysfunction (OD) and concomitant erectile dysfunction (ED) in men with type 1 diabetes (T1D) enrolled in the Epidemiology of Diabetes Interventions and Complications (EDIC) study. In 2010, we assessed orgasmic and erectile function using the International Index of Erectile Function (IIEF). Sociodemographic, clinical, and diabetes characteristics were compared by OD status (OD only, OD and ED, no ED or OD). Age-adjusted associations between risk factors and OD status were examined. OD and ED information was available from 563 men. Eighty-three men (14.7%) reported OD of whom 21 reported OD only and 62 reported OD and ED. Age-adjusted odds ratios demonstrated that men who reported OD only had higher odds of depression, low sexual desire, and decreased alcohol use compared with men reporting no dysfunction. Men with OD concomitant with ED had greater odds of elevated hemoglobin A1C, peripheral and autonomic neuropathy, and nephropathy. Men reporting both dysfunctions were also more likely to report smoking, lower urinary tract symptoms, and had greater odds of androgen deficiency than men with no sexual dysfunction. Men with longstanding T1D suffer from an increased burden of OD. Psychogenic factors predominate in men reporting OD only while men who present with concomitant ED report increased burden of diabetes severity, characteristics previously observed with incident ED. ED may be the central impediment to sexual function in men with OD and ED. Longitudinal studies to characterize OD and ED experience over time are warranted.
