Associations of online religious participation during COVID-19 lockdown with subsequent health and well-being among UK adults.

Background In-person religious service attendance has been linked to favorable health and well-being outcomes. However, little research has examined whether online religious participation improves these outcomes, especially when in-person attendance is suspended. Methods Using longitudinal data of 8951 UK adults, this study prospectively examined the association between frequency of online religious participation during the stringent lockdown in the UK (23 March –13 May 2020) and 21 indicators of psychological well-being, social well-being, pro-social/altruistic behaviors, psychological distress, and health behaviors. All analyses adjusted for baseline socio-demographic characteristics, pre-pandemic in-person religious service attendance, and prior values of the outcome variables whenever data were available. Bonferroni correction was used to correct for multiple testing. Results Individuals with online religious participation of ≥1/week (v. those with no participation at all) during the lockdown had a lower prevalence of thoughts of self-harm in week 20 (odds ratio 0.24; 95% CI 0.09–0.62). Online religious participation of <1/week (v. no participation) was associated with higher life satisfaction (standardized β = 0.25; 0.11–0.39) and happiness (standardized β = 0.25; 0.08–0.42). However, there was little evidence for the associations between online religious participation and all other outcomes (e.g. depressive symptoms and anxiety). Conclusions There was evidence that online religious participation during the lockdown was associated with some subsequent health and well-being outcomes. Future studies should examine mechanisms underlying the inconsistent results for online v. in-person religious service attendance and also use data from non-pandemic situations

Prehospital predicting factors using a decision tree model for patients with witnessed out-of-hospital cardiac arrest and an initial shockable rhythm

The effect of prehospital factors on favorable neurological outcomes remains unclear in patients with witnessed out-of-hospital cardiac arrest (OHCA) and a shockable rhythm. We developed a decision tree model for these patients by using prehospital factors. Using a nationwide OHCA registry database between 2005 and 2020, we retrospectively analyzed a cohort of 1,930,273 patients, of whom 86,495 with witnessed OHCA and an initial shockable rhythm were included. The primary endpoint was defined as favorable neurological survival (cerebral performance category score of 1 or 2 at 1 month). A decision tree model was developed from randomly selected 77,845 patients (development cohort) and validated in 8650 patients (validation cohort). In the development cohort, the presence of prehospital return of spontaneous circulation was the best predictor of favorable neurological survival, followed by the absence of adrenaline administration and age. The patients were categorized into 9 groups with probabilities of favorable neurological survival ranging from 5.7 to 70.8% (areas under the receiver operating characteristic curve of 0.851 and 0.844 in the development and validation cohorts, respectively). Our model is potentially helpful in stratifying the probability of favorable neurological survival in patients with witnessed OHCA and an initial shockable rhythm.Tateishi K., Saito Y., Yasufuku Y., et al.

Histo-Blood Group Antigen-Like Substances of Human Enteric Bacteria as Specific Adsorbents for Human Noroviruses

Histo-blood group antigens (HBGAs) have been suggested to be receptors or coreceptors for human noroviruses (HuNoVs) expressed on the intestinal epithelium. We isolated an enteric bacterium strain (SENG-6), closely related to Enterobacter cloacae, bearing HBGA-like substances from a fecal sample of a healthy individual by using a biopanning technique with anti-HBGA antibodies. The binding capacities of four genotypes of norovirus-like particles (NoVLPs) to Enterobacter sp. SENG-6 cells were confirmed by enzyme-linked immunosorbent assay (ELISA). Transmission electron microscopy demonstrated that NoVLPs bound mainly to extracellular polymeric substances (EPS) of Enterobacter sp. SENG-6, where the HBGA-like substances were localized. EPS that contained HBGA-like substances extracted from Enterobacter sp. SENG-6 was shown by enzyme-linked immunosorbent assay (ELISA) to be capable of binding to NoVLPs of a GI.1 wild-type strain (8fIIa) and a GII.6 strain that can recognize A antigen but not to an NoVLP GI.1 mutant strain (W375A) that loses the ability to bind to A antigen. Enzymatic cleavage of terminal N-acetyl-galactosamine residues in the bacterial EPS weakened bacterial EPS binding to the GI.1 wild-type strain (8fIIa). These results indicate that A-like substances in the bacterial EPS play a key role in binding to NoVLPs. Since the specific binding of HuNoVs to HBGA-positive enteric bacteria is likely to affect the transmission and infection processes of HuNoVs in their hosts and in the environment, further studies of human enteric bacteria and their binding capacity to HuNoVs will provide a new scientific platform for understanding interactions between two types of microbes that were previously regarded as biologically unrelated

Age-related change in contribution of stroke volume to central pulse pressure

We investigated age-related change in the contribution of stroke volume (SV) to central PP (cPP). Eighty seven adult subjects who were free of vasoactive agents were included. Subjects were divided into three age groups: young (20–39 years, n = 26), middle (40–49 years, n = 29), and old (≥50 years, n = 32). SV was calculated by Doppler echocardiography. Hemodynamic indices were measured using a brachial cuff-based oscillometric method. The brachial and cPP showed a small decline from the young group to the middle group and a greater rise after 50 years old. SV significantly and positively correlated with brachial (r = 0.53, p < 0.01) and cPP (r = 0.57, p < 0.01) in the young group. In the middle group, the association of SV with brachial pulse pressure was significant (r = 0.38, p = 0.04) and that with cPP was bordering significant (r = 0.34, p = 0.07). No significant association was found between SV and PP in the old group. In conclusion, the contribution of SV to cPP decreases with age. Age-related changes in the determinants of cPP should be considered when investigating the clinical value of cPP

Report of a case with a spontaneous mesenteric hematoma that ruptured into the small intestine

AbstractIntroductionA spontaneous mesenteric hematoma is a rare condition. Furthermore, it is extremely rare that the mesenteric hematoma caused gastrointestinal bleeding with an unknown etiology. We experienced a case with a spontaneous mesenteric hematoma that ruptured into the jejunum.Presentation of caseA 75-year-old man was referred to our hospital because of anal bleeding and anemia. Abdominal computed tomography (CT) showed a low density mass measuring 3.0cm in diameter, including an enhanced spot. This finding suggested that a pseudo-aneurysm or mesenteric hematoma caused active bleeding into the jejunum. He underwent emergent laparotomy and partial resection of the jejunum and the mesentery including the tumor. A histological examination of the jejunum indicated no pathogenic findings causing active bleeding. And there were no findings suggesting the mesenteric aneurysm had developed.The patient had no history related to the development of a mesenteric hematoma, such as trauma, labor, surgery, or anticoagulant treatment. Therefore, we finally diagnosed that a spontaneous mesenteric hematoma had ruptured into the jejunum.Discussion and conclusionWe reported extremely rare condition that the mesenteric hematoma was developed and ruptured into the jejunum without definitive etiology

Aortic pulsatility assessed by an oscillometric method is associated with coronary atherosclerosis in elderly people

<p>The aim of this study was to investigate the association of aortic pulsatility assessed by a non-invasive brachial cuff-based method with coronary atherosclerosis. In total, 139 patients undergoing coronary angiography were included in this cross-sectional study. Aortic blood pressure (BP) indices were recorded invasively by a fluid-filled catheter and non-invasively by a brachial cuff-based oscillometric device. Fractional pulse pressure (FPP) was defined as pulse pressure (PP)/mean BP and pulsatility index (PI) as PP/diastolic BP. Aortic FPP and PI in coronary artery disease (CAD) patients were significantly higher than in non-CAD patients in both invasive and non-invasive methods. Multivariate logistic regression analysis demonstrated that non-invasively measured aortic FPP and PI were associated with CAD risk in patients aged ≥70 years [aortic FPP per 0.1 odds ratio (OR) = 1.66, 95% confidence interval (CI) 1.05–2.64; aortic PI per 0.1 OR =1.39, 95% CI 1.02–1.88; all <i>p</i> < 0.05], but were not associated with CAD risk in patients aged <70 years. In linear regression analysis, non-invasively measured aortic FPP and PI correlated with SYNTAX and Gensini scores only in patients aged ≥70 years. Aortic FPP and PI measured non-invasively by a brachial cuff-based oscillometric device were associated with coronary atherosclerosis in elderly patients.</p
