Mental health agencies provide critical safety net services for youths. No research has assessed impacts of the COVID-19 pandemic on services these agencies provide or youths they serve. This study sought to characterize agency officials' perceptions of the pandemic's impacts on youths and challenges to providing youth services during the pandemic and to examine associations between these challenges and impacts.

Surveys were completed in September-October 2020 by 159 state or county mental health agency officials from 46 states. Respondents used 7-point scales (higher rating indicated more severe impact or challenge) to rate the pandemic's impact on youth mental health issues, general service challenges, and telepsychiatry service challenges across patient, provider, and financing domains. Multiple linear regression models estimated associations between service challenges (independent variables) and pandemic impacts (dependent variables).

Most agency officials perceived the pandemic as having disproportionately negative mental health impacts on socially disadvantaged youths (serious impact, 72%; mean rating=5.85). Only 15% (mean=4.29) perceived the pandemic as having a seriously negative impact on receipt of needed youth services. Serious service challenges were related to youths' lack of reliable equipment or Internet access for telepsychiatry services (serious challenge, 59%; mean=5.47) and the inability to provide some services remotely (serious challenge, 42%, mean=4.72). In regression models, the inability to provide some services remotely was significantly (p≤0.01) associated with three of five pandemic impacts.

Officials perceived the COVID-19 pandemic as exacerbating youth mental health disparities but as not having a dramatic impact on receipt of needed services.

ICA is recommended for coronary evaluation before heart valvular surgery, and the supporting evidence for CCTA is insufficient. Our study is a single-center, prospective cohort study designed to evaluate the feasibility of CCTA instead of ICA in detection of coronary artery disease before surgery. Methods and Results Heart valvular surgery candidates were consecutively enrolled between April 2017 and December 2018. Nine hundred fifty-eight patients in the CCTA group underwent CCTA primarily, and those with ≥50% coronary stenosis or uncertain diagnosis underwent subsequent ICA. One thousand five hundred twenty-five patients in the ICA group underwent ICA directly before surgery. Coronary artery bypass grafting decision was made by surgeons according to CCTA or ICA results. Most of the patients (78.8%) in the CCTA group avoided invasive angiography. Thirty-day mortality (0.7% versus 0.9%, P=0.821), myocardial infarction (6.4% versus 6.9%, P=0.680 ), and low cardiac output syndrome (4.2% versus 2.8%, P=0.085) were similar in the CCTA and ICA groups. Median duration of follow-up was 19.3 months (interquartile range, 14.2-30.0 months), cumulative rates of mortality (2.6% versus 2.6%, P=0.882) and major adverse cardiac events (9.6% versus 9.0%, P=0.607) showed no difference between the 2 groups. 5-FU order Coronary evaluation expense was lower in the CCTA group ($149.6 versus $636.0, P less then 0.001). Conclusions The strategy of using CCTA as a doorkeeper in coronary evaluation before heart valvular surgery showed noninferiority in identification of candidates for coronary artery bypass grafting and postoperative safety.Background Prevalence of atrial fibrillation (AF) continues to increase and is associated with significant cardiovascular morbidity and mortality. To inform prevention strategies aimed at reducing the burden of AF, we sought to quantify trends in cardiovascular mortality related to AF in the United States. Methods and Results We performed serial cross-sectional analyses of national death certificate data for cardiovascular mortality related to AF, whereby cardiovascular disease was listed as underlying cause of death and AF as multiple cause of death among adults aged 35 to 84 years using the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research. We calculated age-adjusted mortality rates per 100 000 population and examined trends over time, estimating average annual percentage change using the Joinpoint Regression Program. Subgroup analyses were performed by race-sex and across 2 age groups (younger 35-64 years; older 65-84 years). A total of 276 373 cardiovascular deaths related to AF were identified in the United States between 2011 and 2018 in decedents aged 35 to 84 years. Age-adjusted mortality rate increased from 18.0 (95% CI, 17.8-18.2) to 22.3 (95% CI, 22.0-22.4) per 100 000 population between 2011 and 2018. The increase in age-adjusted mortality rate (average annual percentage change) between 2011 and 2018 was greater among younger decedents (7.4% per year [95% CI, 6.8%-8.0%]) compared with older decedents (3.0% per year [95% CI, 2.6%-3.4%]). Conclusions Cardiovascular deaths related to AF are increasing, especially among younger adults, and warrant greater attention to prevention earlier in the life course.There is an urgent need to include a dedicated neurointerventional rotation in the curriculum of neurology residency and vascular neurology fellowship based on the paradigm shift in recent years of stroke workflow. The recent changes coupled with growing body of evidence about lack of neurointerventional exposure in current curriculum makes it imperative for us to restructure the training for future neurologists. The exposure will prepare the neurology house-staff for the contemporary management of cerebrovascular diseases and will lead to high quality, patient-centric care.
Emergency department visits and hospitalizations for stroke declined significantly following declaration of coronavirus disease 2019 (COVID-19) as a national emergency on March 13, 2020, in the United States. This study examined trends in hospitalizations for stroke among Medicare fee-for-service beneficiaries aged ≥65 years and compared characteristics of stroke patients during COVID-19 pandemic to comparable weeks in the preceding year (2019).

For trend analysis, we examined stroke hospitalizations from week 1 in 2019 through week 44 in 2020. For comparison of patient characteristics, we estimated percent reduction in weekly stroke hospitalizations from 2019 to 2020 during weeks 10 through 23 and during weeks 24 through 44 by age, sex, race/ethnicity, and state.

Compared to weekly numbers of hospitalizations for stroke reported during 2019, stroke hospitalizations in 2020 decreased sharply during weeks 10 through 15 (March 1-April 11), began increasing during weeks 16 through 23, and remained at a levneficiaries occurred during initial weeks of the COVID-19 pandemic (March 1-June 6) and weekly stroke hospitalizations remained at a lower than expected level from June 7 to October 31 in 2020 compared with 2019. Changes in stroke hospitalizations varied substantially by state.[Figure see text].The modified Rankin Scale (mRS), a 7-level, clinician-reported, measure of global disability, is the most widely employed outcome scale in acute stroke trials. The scale's original development preceded the advent of modern clinimetrics, but substantial subsequent work has been performed to enable the mRS to meet robust contemporary scale standards. Prior research and consensus recommendations have focused on modernizing 2 aspects of the mRS operationalized assignment of scale scores and statistical analysis of scale distributions. Another important characteristic of the mRS still requiring elaboration and specification to contemporary clinimetric standards is the Naming of scale outcomes. Recent clinical trials have used a bewildering variety, often mutually contradictory, of rubrics to describe scale states. Understanding of the meaning of mRS outcomes by clinicians, patients, and other clinical trial stakeholders would be greatly enhanced by use of a harmonized, uniform set of labels for the distinctive mRS outcomes that would be used consistently across trials. This statement advances such recommended rubrics, developed by the Stroke Therapy Academic Industry Roundtable collaboration using an iterative, mixed-methods process. Specific guidance is provided for health state terms (eg, Symptomatic but Nondisabled for mRS score 1; requires constant care for mRS score 5) and valence terms (eg, excellent for mRS score 1; very poor for mRS score 5) to employ for 23 distinct numeric mRS outcomes, including all individual 7 mRS levels; all 12 positive and negative dichotomized mRS ranges, positive and negative sliding dichotomies; and utility-weighted analysis of the mRS.Background Cardiac fibrosis plays a crucial role in the pathogenesis of dilated cardiomyopathy (DCM). HE4 (human epididymis protein 4) is a secretory protein expressed in activated fibroblasts that exacerbates tissue fibrosis. In the present study, we investigated the clinical utility of HE4 measurement in patients with DCM and its pathophysiological role in preclinical experiments in vivo and in vitro. Methods and Results We measured serum HE4 levels of 87 patients with DCM. Endomyocardial biopsy expressed severe fibrosis only in the high HE4 group (P less then 0.0001). Echocardiography showed that left ventricular end-diastolic diameter tends to decrease over time (58±7.3 to 51±6.6 mm; P less then 0.0001) in the low HE4 group ( less then 59.65 pmol/L [median value]). HE4 was significantly associated with risk reduction of mortality and cardiovascular hospitalization in multivariate Cox model. In vivo, HE4 was highly expressed in kidney and lung tissue of mouse, and scarcely expressed in heart. In genetically induced DCM mouse model, HE4 expression increased in kidney but not in heart and lung. In vitro, supernatant from HE4-transfected human embryonic kidney 293T cells enhanced transdifferentiation of rat neonatal fibroblasts and increased expression of fibrosis-related genes, and this was accompanied by the activation of extracellular signal-regulated kinase signaling in cardiac fibroblasts. Treatment with an inhibitor of upstream signal of extracellular signal-regulated kinase or a neutralizing HE4 antibody canceled the profibrotic properties of HE4. Conclusions HE4 functions as a secretory factor, activating cardiac fibroblasts, thereby inducing cardiac interstitial fibrosis. HE4 could be a promising biomarker for assessing ongoing fibrosis and a novel therapeutic target in DCM.

A routine renal ultrasound revealed a pelvic cyst and CT-scan confirmed a non-complicated cyst but observed a lesion in the left lung.Fabrication and scaling of disordered hyperuniform materials remain hampered by the difficulties in controlling the spontaneous phenomena leading to this novel kind of exotic arrangement of objects. Here, we demonstrate a hybrid top-down/bottom-up approach based on sol-gel dip-coating and nanoimprint lithography for the faithful reproduction of disordered hyperuniform metasurfaces in metal oxides. Nano- to microstructures made of silica and titania can be directly printed over several cm2 on glass and on silicon substrates. First, we describe the polymer mold fabrication starting from a hard master obtained via spontaneous solid-state dewetting of SiGe and Ge thin layers on SiO2. Then, we assess the effective disordered hyperuniform character of master and replica and the role of the thickness of the sol-gel layer on the metal oxide replicas and on the presence of a residual layer underneath. Finally, as a potential application, we show the antireflective character of titania structures on silicon. Our results are relevant for the realistic implementation over large scales of disordered hyperuniform nano- and microarchitectures made of metal oxides, thus opening their exploitation in the framework of wet chemical assembly.
