<b><i>Object:</i></b> The initial amount of subarachnoid and ventricular blood is an important prognostic factor for outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). In this comparative study of an unselected aSAH-population, we assess the modifiability of these factors by implementation of blood clearance by cisternal lavage. <b><i>Methods:</i></b> All patients with aSAH treated in our department between October 2011 and October 2019 (8 years, <i>n</i> = 458) were included in our study. In the first 4-year period (BEFORE, <i>n</i> = 237), patients were treated according to international guidelines. In the second 4-year period (AFTER, <i>n</i> = 221), cisternal lavage methods were available and applied in 72 high-risk patients (32.5%). The cisternal and ventricular blood load was recorded by the Hijdra score. Multivariable regression models were used to assess the prognostic significance of risk factors, including blood load, in relation to common aSAH characteristics in both study groups. <b><i>Results:</i></b> Worse neurological outcomes (mRS &#x3e; 3) occurred in the BEFORE population with 41.45% versus 30.77% in the AFTER cohort, 6 months after aSAH (HR: 1.59, 95% CI 1.08–2.34, <i>p</i> = 0.01). Admission WFNS grade, comorbidities (Charlson Comorbidity Index), herniation signs, concomitant intracerebral hemorrhage, and the development of delayed cerebral infarction were strongly associated with poor outcome in both study groups. Intraventricular and cisternal blood load and, particularly, a cast fourth ventricle (Cast 4) represented strong prognosticators of poor neurological outcome in the BEFORE cohort. This effect was lost after implementation of cisternal lavage (AFTER cohort). <b><i>Conclusion:</i></b> Cisternal and ventricular blood load – in particular: a Cast 4 – represent important prognosticators in patients with aSAH. They are, however, amenable to modification by blood clearing therapies.

Medulloblastoma (MB) is a childhood malignant brain tumour but also occurs in teenagers and young adults (TYA). Considering that MB is heterogeneous, this study aimed to define the molecular landscape of MBs in TYAs. We collated more than 2000 MB samples that included 287 TYA patients (13–24 years). We performed computational analyses consisting of genome-wide methylation and transcriptomic profiles and developed a prognostics model for the TYAs with MB. We identified that TYAs predominantly comprised of Group 4 (40%) and Sonic Hedgehog (SHH)-activated (33%) tumours, with Wingless-type (WNT, 17%) and Group 3 (10%) being less common. TYAs with SHH tumours displayed significantly more gene expression alterations, whereas no gene was detected in the Group 4 tumours. Across MB subgroups, we identified unique and shared sets of TYA-specific differentially methylated probes and DNA-binding motifs. Finally, a 22-gene signature stratified TYA patients into high- and low-risk groups, and the prognostic significance of these risk groups persisted in multivariable regression models (P = 0.001). This study is an important step toward delineating the molecular landscape of TYAs with MB. The emergence of novel genes and pathways may provide a basis for improved clinical management of TYA with MB.

ObjectiveTo understand the reach of the community health worker (CHW) programme in remote and non-remote districts of Afghanistan.MethodsUsing data collected from the Ministry of Public Health’s National Health Management Information System, we conducted a population-based study from 2018 to 2019 in 401 districts across 34 provinces of Afghanistan. We assessed the availability of CHWs, antenatal visits (ANV) and postnatal visits (PNV) conducted by the CHWs, and the availability of CHW supplies. Districts were classified as remote if the district centre was >2 hours by any form of transport from provincial capital, and non-remote if <2 hours. Data were analysed using multivariable regression models.Results15 562 CHWs were working in the districts of Afghanistan, 13 482 (87%) in remote and 2080 (13%) in non-remote districts. The mean of the proportion of CHWs per pregnant woman was higher in remote (0.019 (SD 0.011)) compared with non-remote (0.012 (SD 0.006)) districts (adjusted mean difference (AMD) 0.008, 95% CI 0.004 to 0.01). The mean of the proportion of ANVs received from a CHW per pregnant women was higher in remote (0.88 (SD 0.82)) compared with non-remote (0.62 (SD 0.50)) districts (AMD 0.28, 95% CI 0.02 to 0.54). The mean of the proportion of PNVs received from a CHW per pregnant women was higher in remote (0.54 (SD 0.53)) compared with non-remote (0.36 (SD 0.25)) districts (AMD 0.19, 95% CI 0.02 to 0.36). The mean of the proportion of CHWs who reported that they had stocks of cotrimoxazole and oral contraceptives in the previous month per district was higher in remote compared with non-remote districts.ConclusionsIn Afghanistan, the CHW programme appears to be effective and proportionate to need in remote regions.

Background and Objectives: The aim of this study was to assess the association between prehospital peripheral oxygen saturation (SpO2) and intensive care unit (ICU) admission in confirmed or suspected coronavirus disease 19 (COVID-19) patients. Materials and Methods: We carried out a retrospective cohort study on patients requiring prehospital intervention between 11 March 2020 and 4 May 2020. All adult patients in whom a diagnosis of COVID-19 pneumonia was suspected by the prehospital physician were included. Patients who presented a prehospital confounding respiratory diagnosis and those who were not eligible for ICU admission were excluded. The main exposure was “Low SpO2” defined as a value < 90%. The primary outcome was 48-h ICU admission. Secondary outcomes were 48-h mortality and 30-day mortality. We analyzed the association between low SpO2 and ICU admission or mortality with univariable and multivariable regression models. Results: A total of 145 patients were included. A total of 41 (28.3%) patients had a low prehospital SpO2 and 21 (14.5%) patients were admitted to the ICU during the first 48 h. Low SpO2 was associated with an increase in ICU admission (OR = 3.4, 95% CI = 1.2–10.0), which remained significant after adjusting for sex and age (aOR = 5.2, 95% CI = 1.8–15.4). Mortality was higher in low SpO2 patients at 48 h (OR = 7.1 95% CI 1.3–38.3) and at 30 days (OR = 3.9, 95% CI 1.4–10.7). Conclusions: In our physician-staffed prehospital system, first low prehospital SpO2 values were associated with a higher risk of ICU admission during the COVID-19 pandemic.

Abstract The longitudinal associations between hearing impairment and higher-level functional measures and the potential confounding role of vestibular function have not been assessed. We investigated these associations in 831 participants of the Baltimore Longitudinal Study of Aging (2012–2019). Hearing was measured using pure-tone audiometry and categorized using WHO standards. Physical function was assessed with the Health Aging and Body Composition Physical Performance Battery (HABCPPB, higher=better) and walking endurance with time to walk 400 meters. Multivariable regression models tested the hypotheses that participants with hearing impairment have poorer physical outomes. In a subset, we further adjusted for vestibular function. Hearing impairment was associated with decrements in higher-level physical performance and walking endurance, and faster decline over time, regardless of vestibular function. Among participants with any hearing impairment, hearing aid users were faster in the 400-m walk. Early screening for higher-level functional loss among older adults with hearing loss is warranted.

Abstract We examined four states with data on LGBTQ+ identity and the ADRD caregiving modules from the 2019 Behavioral Risk Factor Surveillance System. Multivariable regression models examined the associations between LGBTQ+ identity and health outcomes. Among the ADRD caregivers, 55,920 (4.7%) identified as LGBTQ+. Compared with non-LGBTQ+ caregivers, LGBTQ+ caregivers were younger and more likely to live in rural counties. Half of LGBTQ+ caregivers spent 20+ hours per week providing care, and nearly 72% reported helping with personal care. LGBTQ+ caregivers reported more days when their mental health was not good than non-LGBTQ+ caregivers (B = 8.01;95% CI= 2.32-13.75). Female caregivers overall were twice as likely than males to experience depression (OR = 2.11;95% CI=1.29-3.45). These findings provide insight into characteristics of LGBTQ+ caregivers and their health concerns. Interventions that promote mental health and reach diverse LGBTQ+ caregivers in rural communities are crucial in supporting LGBTQ+ caregivers of people with ADRD.

Abstract Background Defining the metabolic syndrome (MetS) in children remains challenging. Furthermore, a dichotomous MetS diagnosis can limit the power to study associations. We sought to characterize the serum metabolite signature of the MetS in early childhood using high-throughput metabolomic technologies that allow comprehensive profiling of metabolic status from a biospecimen. Methods In the Family Atherosclerosis Monitoring In earLY life (FAMILY) prospective birth cohort study, we selected 228 cases of MetS and 228 matched controls among children age 5 years. In addition, a continuous MetS risk score was calculated for all 456 participants. Comprehensive metabolite profiling was performed on fasting serum samples using multisegment injection-capillary electrophoresis-mass spectrometry. Multivariable regression models were applied to test metabolite associations with MetS adjusting for covariates of screen time, diet quality, physical activity, night sleep, socioeconomic status, age, and sex. Results Compared to controls, thirteen serum metabolites were identified in MetS cases when using multivariable regression models, and using the quantitative MetS score, an additional eight metabolites were identified. These included metabolites associated with gluconeogenesis (glucose (odds ratio (OR) 1.55 [95% CI 1.25–1.93]) and glutamine/glutamate ratio (OR 0.82 [95% CI 0.67–1.00])) and the alanine-glucose cycle (alanine (OR 1.41 [95% CI 1.16–1.73])), amino acids metabolism (tyrosine (OR 1.33 [95% CI 1.10–1.63]), threonine (OR 1.24 [95% CI 1.02–1.51]), monomethylarginine (OR 1.33 [95% CI 1.09–1.64]) and lysine (OR 1.23 [95% CI 1.01–1.50])), tryptophan metabolism (tryptophan (OR 0.78 [95% CI 0.64–0.95])), and fatty acids metabolism (carnitine (OR 1.24 [95% CI 1.02–1.51])). The quantitative MetS risk score was more powerful than the dichotomous outcome in consistently detecting this metabolite signature. Conclusions A distinct metabolite signature of pediatric MetS is detectable in children as young as 5 years old and may improve risk assessment at early stages of development.

Background: The relationship between thyroid function and cardiac disease is complex. Both hypothyroidism and thyrotoxicosis can predispose to ventricular arrhythmia and other major adverse cardiovascular events (MACE), so that a U-shaped relationship between thyroid signaling and the incidence of MACE has been postulated. Moreover, recently published data suggest an association between thyroid hormone concentration and the risk of sudden cardiac death (SCD) even in euthyroid populations with high-normal FT4 levels. In this study, we investigated markers of repolarization in ECGs, as predictors of cardiovascular events, in patients with a spectrum of subclinical and overt thyroid dysfunction.Methods: Resting ECGs of 100 subjects, 90 patients (LV-EF &gt; 45%) with thyroid disease (60 overt hyperthyroid, 11 overt hypothyroid and 19 L-T4-treated and biochemically euthyroid patients after thyroidectomy or with autoimmune thyroiditis) and 10 healthy volunteers were analyzed for Tp-e interval. The Tp-e interval was measured manually and was correlated to serum concentrations of thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and thyroxine (FT4).Results: The Tp-e interval significantly correlated to log-transformed concentrations of TSH (Spearman's rho = 0.30, p &lt; 0.01), FT4 (rho = −0.26, p &lt; 0.05), and FT3 (rho = −0.23, p &lt; 0.05) as well as log-transformed thyroid's secretory capacity (SPINA-GT, rho = −0.33, p &lt; 0.01). Spearman's rho of correlations of JT interval to log-transformed TSH, FT4, FT3, and SPINA-GT were 0.51 (p &lt; 1e−7), −0.45 (p &lt; 1e−5), −0.55 (p &lt; 1e−8), and −0.43 (p &lt; 1e−4), respectively. In minimal multivariable regression models, markers of thyroid homeostasis correlated to heart rate, QT, Tp-e, and JT intervals. Group-wise evaluation in hypothyroid, euthyroid and hyperthyroid subjects revealed similar correlations in all three groups.Conclusion: We observed significant inverse correlations of Tp-e and JT intervals with FT4 and FT3 over the whole spectrum of thyroid function. Our data suggest a possible mechanism of SCD in hypothyroid state by prolongation of repolarization. We do not observe a U-shaped relationship, so that the mechanism of SCD in patients with high FT4 or hyperthyroidism seems not to be driven by abnormalities in repolarization.

Childcare arrangements shape behavioural patterns that influence the risk of childhood obesity. However, little is known of its influence on childhood obesity in Singapore. We aim to examine the associations between childcare arrangements at the age of 5 years and childhood adiposity at age 6 years. Children from the GUSTO study were grouped into three childcare arrangements at age 5: full-time centre-based childcare (FC), partial centre-based with parental care (PCP), and partial centre-based with non-parents (grandparents and domestic helpers) as caregivers (PCN). Diet, physical activity and sedentary behaviour information were collected at age 5, while anthropometric measurements were collected at age 6. Associations were analysed using multivariable regression models. Among 540 children, those in PCN had higher BMI z-scores (β: 0.34; 95% CI: 0.01, 0.66), greater sum of skinfold thicknesses (mm) (β: 3.75; 95% CI: 0.53, 6.97) and were 3.55 times (95% CI: 1.78, 7.05) more likely to be overweight/obese than those in FC. Adiposity measures in PCP children did not differ from those in FC. PCN children were reported to have more screen time and greater fast-food intake. Children in PCN tended to have higher adiposity measures. Greater engagement of non-parental caregivers should be considered in interventions targeting child obesity.
