Was there a weekend effect on mortality rates for hospitalized patients with COVID-19 and acute myocardial infarction? Insights from the National Inpatient Sample, 2020.

Our study aimed to assess the effect of weekend versus weekday hospital admissions on all-cause mortality in patients with acute myocardial infarction (AMI) and COVID-19 during the COVID-19 pandemic. We analyzed data from the National Inpatient Sample (NIS) 2020, identifying patients with co-existing AMI and COVID-19 admitted on weekdays and weekends. Baseline demographics, comorbidities, and outcomes were assessed. A multivariable regression analysis was conducted, adjusting for confounders to determine the odds of all-cause mortality. Among 74,820 patients, 55,145 (73.7%) were admitted on weekdays, while 19,675 (26.3%) were admitted on weekends. Weekend admissions showed slightly higher proportions of men (61.3% vs. 60%) and whites (56.3% vs. 54.9%) with a median age of 73 years (range: 62-82). The overall all-cause mortality had an odds ratio (OR) of 1.00 (95% CI, 0.92-1.09; P = 0.934). After adjusting for covariates, there was no significant associations between mortality and hospital type (rural: OR = 1.04; 95% CI, 0.78-1.39; P = 0.789; urban teaching: OR = 1.04; 95% CI, 0.94-1.14; P = 0.450) or geographic region (Northeast: OR = 1.16; 95% CI, 0.96-1.39; P = 0.12; Midwest: OR = 0.99; 95% CI, 0.83-1.17; P = 0.871; South: OR = 0.97; 95% CI, 0.85-1.12; P = 0.697; West: OR = 0.94; 95% CI, 0.77-1.15; P = 0.554). There was no significant difference in the rate of all-cause mortality among patients admitted for AMI and COVID-19 between weekdays and weekends.

A comparative study of the definitions of intradialytic hypotension correlated with increased mortality to identify universal predictors.

Intradialytic hypotension (IDH) is a common complication in patients undergoing hemodialysis therapy. No consensus on the definition of intradialytic hypotension has been established so far. As a result, coherent and consistent evaluation of its effects and causes is difficult. Some studies have highlighted existing correlations between certain definitions of IDH and the risk of mortality for the patients. This work is mainly focused on these definitions. Our aim is to understand if different IDH definitions, all correlated with increased mortality risk, catch the same onset mechanisms or dynamics. To check whether the dynamics captured by these definitions are similar, we performed analyses of the incidence, of the IDH event onset timing, and checked whether there were similarities between the definitions in those aspects. We evaluated how these definitions overlap with each other and we evaluated which common factors could allow identifying patients at risk of IDH at the beginning of a dialysis session. The definitions of IDH we analyzed through statistical and machine learning approaches, showed a variable incidence on the HD sessions and had different onset time. We found that the set of parameters relevant for the prediction of the IDH was not always the same for the definitions considered. However, it can be observed that some predictors, such as the presence of comorbidities such as diabetes or heart disease, and a low pre-dialysis diastolic blood pressure, have shown universal relevance in highlighting an increased risk of IDH during the treatment. Among those parameters, the one that showed a major importance is the diabetes status of the patients. Diabetes or heart disease presence are permanent risk factors pointing out an increased IDH risk during the treatments, while, pre-dialysis diastolic blood pressure is instead a parameter that can change at every session and should be used to evaluate the specific risk to develop IDH for each session. The identified parameters could be used in the future to train more complex prediction models.

Association of germline variants in telomere maintenance genes (POT1, TERF2IP, ACD, and TERT) with spitzoid morphology in familial melanoma: A multi-center case series.

Background: Spitzoid morphology in familial melanoma has been associated with germline variants in POT1, a telomere maintenance gene (TMG), suggesting a link between telomere biology and spitzoid differentiation. Objective: To assess if familial melanoma cases associated with germline variants in TMG (POT1, ACD, TERF2IP, and TERT) commonly exhibit spitzoid morphology. Methods: In this case series, melanomas were classified as having spitzoid morphology if at least 3 of 4 dermatopathologists reported this finding in ≥25% of tumor cells. Logistic regression was used to calculate odds ratios (OR) of spitzoid morphology compared to familial melanomas from unmatched noncarriers that were previously reviewed by a National Cancer Institute dermatopathologist. Results: Spitzoid morphology was observed in 77% (23 of 30), 75% (3 of 4), 50% (2 of 4), and 50% (1 of 2) of melanomas from individuals with germline variants in POT1, TERF2IP, ACD, and TERT, respectively. Compared to noncarriers (n = 139 melanomas), POT1 carriers (OR = 225.1, 95% confidence interval: 51.7-980.5; P < .001) and individuals with TERF2IP, ACD, and TERT variants (OR = 82.4, 95% confidence interval: 21.3-494.6; P < .001) had increased odds of spitzoid morphology. Limitations: Findings may not be generalizable to nonfamilial melanoma cases. Conclusion: Spitzoid morphology in familial melanoma could suggest germline alteration of TMG.

Preventive or promotive effects of PRNP polymorphic heterozygosity on the onset of prion disease.

The polymorphic heterozygosity of PRNP at codon 129 or 219 prevents the onset of sporadic Creutzfeldt-Jakob disease (sCJD). We investigated the association between polymorphic genotypes at codon 129 or 219 and comprehensive prion disease onset using non-CJD as a reference. EK heterozygotes at codon 219, versus EE homozygotes, showed a preventive effect on the extensive prion diseases-sCJD, genetic CJD (gCJD) with V180I or M232R mutation, and Gerstmann-Straussler-Scheinker disease with P102L mutation. No preventive effect was observed for E200K-gCJD and dura-grafted CJD (dCJD) in 129 MV and 219 EK heterozygotes. It was suggested that unlike other prion diseases, E200K-gCJD may not benefit from the preventive effect of 219 EK heterozygosity because complementary electrostatic interactions between PrP molecules at K200 and E219 might make homodimer formation easier. Comparison of sCJD and dCJD indicates that 219 EK heterozygosity strongly inhibits de novo synthesis of PrPSc (initial PrPSc formation), but does not inhibit accelerated propagation of existing PrPSc.

High producer variant of lipoprotein lipase may protect from hepatocellular carcinoma in alcohol-associated cirrhosis.

Background & Aims: Progression of alcohol-associated liver disease (ALD) is driven by genetic predisposition. The rs13702 variant in the lipoprotein lipase (LPL) gene is linked to non-alcoholic fatty liver disease. We aimed at clarifying its role in ALD. Methods: Patients with alcohol-associated cirrhosis, with (n = 385) and without hepatocellular carcinoma (HCC) (n = 656), with HCC attributable to viral hepatitis C (n = 280), controls with alcohol abuse without liver damage (n = 366), and healthy controls (n = 277) were genotyped regarding the LPL rs13702 polymorphism. Furthermore, the UK Biobank cohort was analysed. LPL expression was investigated in human liver specimens and in liver cell lines. Results: Frequency of the LPL rs13702 CC genotype was lower in ALD with HCC in comparison to ALD without HCC both in the initial (3.9% vs. 9.3%) and the validation cohort (4.7% vs. 9.5%; p <0.05 each) and compared with patients with viral HCC (11.4%), alcohol misuse without cirrhosis (8.7%), or healthy controls (9.0%). This protective effect (odds ratio [OR] = 0.5) was confirmed in multivariate analysis including age (OR = 1.1/year), male sex (OR = 3.0), diabetes (OR = 1.8), and carriage of the PNPLA3 I148M risk variant (OR = 2.0). In the UK Biobank cohort, the LPL rs13702 C allele was replicated as a risk factor for HCC. Liver expression of LPL mRNA was dependent on LPL rs13702 genotype and significantly higher in patients with ALD cirrhosis compared with controls and alcohol-associated HCC. Although hepatocyte cell lines showed negligible LPL protein expression, hepatic stellate cells and liver sinusoidal endothelial cells expressed LPL. Conclusions: LPL is upregulated in the liver of patients with alcohol-associated cirrhosis. The LPL rs13702 high producer variant confers protection against HCC in ALD, which might help to stratify people for HCC risk. Impact and implications: Hepatocellular carcinoma is a severe complication of liver cirrhosis influenced by genetic predisposition. We found that a genetic variant in the gene encoding lipoprotein lipase reduces the risk for hepatocellular carcinoma in alcohol-associated cirrhosis. This genetic variation may directly affect the liver, because, unlike in healthy adult liver, lipoprotein lipase is produced from liver cells in alcohol-associated cirrhosis.

Rates of breastfeeding or chestfeeding and influencing factors among transgender and gender-diverse parents: a cross sectional study.

Background: Breastfeeding is essential for the growth and development of all infants. Despite the large transgender and gender-diverse population size, there is no comprehensive research of breastfeeding or chestfeeding practices in this group. This study was designed aimed to investigate the status of breastfeeding or chestfeeding practices in transgender and gender-diverse parents and to explore the possible influencing factors. Methods: A cross-sectional study was conducted between January 27 2022 and February 15 2022 online in China. A representative sample of 647 transgender and gender-diverse parents was enrolled. Validated questionnaires were used to investigate breastfeeding or chestfeeding practices and its associated factors, including physical factors, psychological factors and socio-environmental factors. Findings: The exclusive breastfeeding or chestfeeding rate was 33.5% (214) and only 41.3% (244) of infants could be continuously fed until 6 months. Accepting hormonotherapy after having this child (adjusted odds ratio (AOR) = 1.664, 95% confidential interval (CI) = 1.014∼2.738) and receiving feeding education (AOR = 2.161, 95% CI = 1.363∼3.508) were associated with a higher exclusive breastfeeding or chestfeeding rate, while higher gender dysphoria scores (37-47: AOR = 0.549, 95% CI = 0.364∼0.827; >47: AOR = 0.474, 95% CI = 0.286∼0.778), experiencing family violence (15-35: AOR = 0.388, 95% CI = 0.257∼0.583; >35: AOR = 0.335; 95% CI = 0.203∼0.545), experiencing partner violence (≥30: AOR = 0.541, 95% CI = 0.334∼0.867), using artificial insemination (AOR = 0.269, 95% CI = 0.12∼0.541), or surrogacy (AOR = 0.406, 95% CI = 0.199∼0.776) and being discriminated against during seeking of childbearing health care (AOR = 0.402, 95% CI = 0.28∼0.576), are significantly associated with a lower exclusive breastfeeding or chestfeeding rate. Participants who had feeding education were more likely to feed their child with human milk as the first food intake (AOR = 1.644, 95% CI = 1.015∼2.632), while those who had suffered from family violence (>35: AOR = 0.47; 95% CI = 0.259∼0.84), discrimination (AOR = 0.457, 95% CI = 0.284∼0.721) and chose artificial insemination (AOR = 0.304, 95% CI = 0.168∼0.56) or surrogacy (AOR = 0.264, 95% CI = 0.144∼0.489), were less likely to give their child human milk as first food intake. Besides, discrimination is also related to a shorter breastfeeding or chestfeeding duration (AOR = 0.535, 95% CI = 0.375∼0.761). Interpretation: Breastfeeding or chestfeeding are neglected health problems in the transgender and gender-diverse population and many socio-demographic factors, transgender and gender-diverse-related factors, and family environment are correlated with it. Better social and family support is necessary to improve breastfeeding or chestfeeding practices. Funding: There are no funding sources to declare.

Impact of the COVID-19 pandemic on prehospital characteristics and outcomes of out-of-hospital cardiac arrest among the elderly in Japan: A nationwide study.

Aim: To assess the impact of the 2020 coronavirus disease (COVID-19) pandemic on the prehospital characteristics and outcomes of out-of-hospital cardiac arrest (OHCA) in the elderly. Methods: In this population-based nationwide observational study in Japan, 563,100 emergency medical service-unwitnessed OHCAs in elderly (≥65 years) patients involving any prehospital resuscitation efforts were analysed (144,756, 140,741, 140,610, and 136,993 cases in 2020, 2019, 2018, and 2017, respectively). The epidemiology, characteristics, and outcomes associated with OHCAs in elderly patients were compared between 3 years pre-pandemic (2017-2019) and the pandemic year (2020). The primary outcome was neurologically favourable one-month survival. The secondary outcomes were the rate of bystander cardiopulmonary resuscitation (CPR), defibrillation by a bystander, dispatcher-assisted (DA)-CPR attempts, and one-month survival. Results: During the pandemic year, the rates of neurologically favourable 1-month survival (crude odds ratio, 95% confidence interval: 1.19, 1.14-1.25), bystander CPR (1.04, 1.03-1.06), and DA-CPR attempts (1.10, 1.08-1.11) increased, whereas the incidence of public access defibrillation (0.88, 0.83-0.93) decreased. Subgroup analyses based on interaction tests showed that the increased rate of neurologically favourable survival during the pandemic year was enhanced in OHCA at care facilities (1.51, 1.36-1.68) and diminished or abolished on state-of-emergency days (0.90, 0.74-1.09), in the mainly affected prefectures (1.08, 1.01-1.15), and in cases with shockable initial rhythms (1.03, 0.96-1.12). Conclusions: The COVID-19 pandemic increased the bystander CPR rate in association with enhanced DA-CPR attempts and improved the outcomes of elderly patients with OHCAs.

Neuropsychiatric disorders in adults undergoing chimeric antigen receptor T cells therapy for aggressive lymphomas and acute lymphoblastic leukemia.

Objective: To evaluate risk factors for neuropsychiatric disorders (NPD) in recipients of CART therapy. Methods: Patients ≥ 18 years with acute lymphoblastic leukemia (ALL), and aggressive B-cell lymphomas who received CART in 2018 were evaluated. Patients with and without NPD were compared. Results: NPD was diagnosed in 31.2% of patients. Compared to patients without NPD, patients with NPD were likely to be females (P = 0.035) and have ALL (P = 0.039). NPD was significantly associated with female gender (OR = 2.03) and diagnosis of ALL (OR = 2.76). No association between NPD and outcomes. Conclusions: Female gender and ALL were risk factors for NPD.

Prognosis in Patients With Cardiogenic Shock Who Received Temporary Mechanical Circulatory Support.

Background: Temporary mechanical circulatory support (MCS) is often used in patients with cardiogenic shock (CS), and the type of MCS may vary by cause of CS. Objectives: This study sought to describe the causes of CS in patients receiving temporary MCS, the types of MCS used, and associated mortality. Methods: This study used a nationwide Japanese database to identify patients receiving temporary MCS for CS between April 1, 2012, and March 31, 2020. Results: Of 65,837 patients, the cause of CS was acute myocardial infarction (AMI) in 77.4%, heart failure (HF) in 10.9%, valvular disease in 2.7%, fulminant myocarditis (FM) in 2.5%, arrhythmia in 4.5%, and pulmonary embolism (PE) in 2.0% of cases. The most commonly used MCS was an intra-aortic balloon pump alone in AMI (79.2%) and in HF (79.0%) and in valvular disease (66.0%), extracorporeal membrane oxygenation with intra-aortic balloon pump in FM (56.2%) and arrhythmia (43.3%), and extracorporeal membrane oxygenation alone in PE (71.5%). Overall in-hospital mortality was 32.4%; 30.0% in AMI, 32.6% in HF, 33.1% in valvular disease, 34.2% in FM, 60.9% in arrhythmia, and 59.2% in PE. Overall in-hospital mortality increased from 30.4% in 2012 to 34.1% in 2019. After adjustment, valvular disease, FM, and PE had lower in-hospital mortality than AMI: valvular disease, OR: 0.56 (95% CI: 0.50-0.64); FM: OR: 0.58 (95% CI: 0.52-0.66); PE: OR: 0.49 (95% CI: 0.43-0.56); whereas HF had similar in-hospital mortality (OR: 0.99; 95% CI: 0.92-1.05) and arrhythmia had higher in-hospital mortality (OR: 1.14; 95% CI: 1.04-1.26). Conclusions: In a Japanese national registry of patients with CS, different causes of CS were associated with different types of MCS and differences in survival.

Elevated serum levels of glial fibrillary acidic protein are associated with covert hepatic encephalopathy in patients with cirrhosis.

Background & Aims: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. Astrocyte swelling is a major component of hepatic encephalopathy. Thus, we hypothesised that glial fibrillary acidic protein (GFAP), the major intermediate filament of astrocytes, might facilitate early diagnosis and management. This study aimed to investigate the utility of serum GFAP (sGFAP) levels as a biomarker of CHE. Methods: In this bicentric study, 135 patients with cirrhosis, 21 patients with ongoing harmful alcohol use and cirrhosis, and 15 healthy controls were recruited. CHE was diagnosed using psychometric hepatic encephalopathy score. sGFAP levels were measured using a highly sensitive single-molecule array (SiMoA) immunoassay. Results: In total, 50 (37%) people presented with CHE at study inclusion. Participants with CHE displayed significantly higher sGFAP levels than those without CHE (median sGFAP, 163 pg/ml [IQR 136; 268] vs. 106 pg/ml [IQR 75; 153]; p <0.001) or healthy controls (p <0.001). sGFAP correlated with results in psychometric hepatic encephalopathy score (Spearman's ρ = -0.326, p <0.001), model for end-stage liver disease score (Spearman's ρ = 0.253, p = 0.003), ammonia (Spearman's ρ = 0.453, p = 0.002), and IL-6 serum levels (Spearman's ρ = 0.323, p = 0.006). Additionally, sGFAP levels were independently associated with the presence of CHE in multivariable logistic regression analysis (odds ratio 1.009; 95% CI 1.004-1.015; p <0.001). sGFAP levels did not differ between patients with alcohol-related cirrhosis vs. patients with non-alcohol-related cirrhosis or between patients with ongoing alcohol use vs. patients with discontinued alcohol use.Conclusions: sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker. Impact and implications: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. In this study, we were able to demonstrate that sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker.

Rare Dysfunctional Complement Factor I Genetic Variants and Progression to Advanced Age-Related Macular Degeneration.

Purpose: To evaluate associations between rare dysfunctional complement factor I (CFI) genetic variant status and progression to advanced age-related macular degeneration (AAMD), geographic atrophy (GA), and neovascular disease (NV). Design: Prospective, longitudinal study. Participants: Patients aged 55 to 80 years at baseline identifying as White with non-AAMD in 1 or both eyes at baseline were included. Follow-up grades were assigned as early, intermediate, or AAMD (GA or NV). CFI variants were categorized using genotyping and sequencing platforms. Methods: Analyses were performed using the Seddon Longitudinal Cohort Study (N = 2116 subjects, 3901 eyes, and mean follow-up of 8.3 years) and the Age-Related Eye Disease Study (N = 2837 subjects, 5200 eyes, and mean follow-up of 9.2 years). CFI rare variants associated with low serum factor I (FI) protein levels and decreased FI function (type 1), other AMD genetic variants, and demographic, behavioral, and ocular factors were evaluated. Generalized estimating equations methods were used to assess the association between CFI rare variants and progression, independent of other genetic variants and covariates. Main Outcome Measures: Progression to AAMD, GA, or NV. Results: In the prospective cohort of 4953 subjects (9101 eyes with non-AAMD at baseline), 1% were type 1 rare CFI carriers. Over 12 years, progression to AAMD was 44% for carriers and 20% for noncarriers (P < 0.001), 30% of carriers versus 10% of noncarriers progressed to GA (P < 0.001), and 18% of carriers compared with 11% of noncarriers progressed to NV (P = 0.049). CFI carriers were more likely to have a family history of AMD (P for trend = 0.035) and a higher baseline AMD grade (P < 0.001). After adjusting for all covariates, CFI carrier status was associated with progression to GA (odds ratio [OR] = 1.91; 95% confidence interval [CI] = 1.03, 3.52) but not NV (OR = 0.96). Higher body mass index was associated with progression among CFI carriers (body mass index ≥ 25 vs. < 25; OR = 5.8; 95% CI 1.5, 22.3) but not for noncarriers (OR = 1.1; 95% CI = 0.9, 1.3), with P_interaction = 0.011. Conclusions: Results suggest that carriers of rare dysfunctional type 1 CFI variants are at higher risk for progression to AAMD with GA.

Time to sputum conversion in patients with pulmonary tuberculosis: A score to estimate the infectious period.

Introduction: Patients with pulmonary tuberculosis (PTB) disease and positive sputum cultures are the main source of infection. Culture conversion time is inconsistent and defining the length of respiratory isolation is challenging. The objective of this study is to develop a score to predict the length of isolation period. Methods: A retrospective study was carried out to evaluated risk factors associated with persistent positive sputum cultures after 4 weeks of treatment in 229 patients with PTB. A multivariable logistic regression model was used to determinate predictors for positive culture and a scoring system was created based on the coefficients of the final model. Results: Sputum culture was persistently positive in 40.6%. Fever at consultation (1.87, 95% CI:1.02-3.41), smoking (2.44, 95% CI:1.36-4.37), >2 affected lung lobes (1.95, 95% CI:1.08-3.54), and neutrophil-to-lymphocyte ratio > 3.5 (2.22, 95% CI:1.24-3.99), were significantly associated with delayed culture conversion. Therefore, we assembled a severity score that achieved an area under the curve of 0.71 (95% CI:0.64-0.78). Conclusions: In patients with smear positive PTB, a score with clinical, radiological and analytical parameters can be used as a supplemental tool to assist clinical decisions in isolation period.

Corticosteroids and Outcomes in Solid Organ Transplant Recipients Infected With Severe Acute Respiratory Syndrome Coronavirus 2.

Objective: To examine outcomes in organ transplant and nontransplant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the initial 22 months of the pandemic. Patients and Methods: We used Optum electronic health records to compare outcomes between an adult transplant group and a propensity-matched nontransplant group that tested positive for SARS-CoV-2 from February 1, 2020, to December 15, 2021. Baseline characteristics, hospitalization, intensive care unit admission, mechanical ventilation, renal replacement therapy, inpatient, and 90-day mortality were compared between the transplant and nontransplant groups and among specific transplant recipients. Cox proportional analysis was used to examine hospitalization and mortality by organ transplant, medical therapy, sex, and the period of the pandemic. Results: We identified 876,959 patients with SARS-CoV-2 infection, of whom 3548 were organ transplant recipients. The transplant recipients had a higher risk of hospitalization (30.6% vs 25%, respectively; P<.001), greater use of mechanical ventilation (7.8% vs 5.6%, respectively; P<.001), and increased inpatient mortality (6.7% vs 4.7%, respectively; P<.001) compared with the nontransplant patients. The initiation of mechanical ventilation was significantly more frequent in the transplant group. After adjustment for baseline characteristics and comorbidities, the transplant group had a higher risk of hospitalization (odds ratio, 1.38; 95% confidence interval, 1.19-1.59), without a difference in mortality. In the transplant group, lung transplant recipients had the highest inpatient mortality (11.6%). Conclusion: Among patients with SARS-CoV-2 infection, the transplant recipients were at a higher risk of hospitalization and inpatient mortality; however, mortality was mainly driven by advanced age and comorbidities rather than by transplant status or immunosuppressive medications. Lung transplant recipients had the greatest inpatient and 90-day mortality.

Neighborhood deprivation and morbid obesity: Insights from the Houston Methodist Cardiovascular Disease Health System Learning Registry.

This study examined the relationship between a validated measure of socioeconomic deprivation, such as the Area Deprivation Index (ADI), and morbid obesity. We used cross-sectional data on adult patients (≥18 years) in the Houston Methodist Cardiovascular Disease Health System Learning Registry (located in Houston, Texas, USA) between June 2016 and July 2021. Each patient was grouped by quintiles of ADI, with higher quintiles signaling greater deprivation. BMI was calculated using measured height and weight with morbid obesity defined as ≥ 40 kg/m2. Multivariable logistic regression models were used to examine the association between ADI and morbid obesity adjusting for demographic (age, sex, and race/ethnicity) factors. Out of the 751,174 adults with an ADI ranking included in the analysis, 6.9 % had morbid obesity (n = 51,609). Patients in the highest ADI quintile had a higher age-adjusted prevalence (10.9 % vs 3.3 %), and about 4-fold odds (aOR, 3.8; 95 % CI = 3.6, 3.9) of morbid obesity compared to the lowest ADI quintile. We tested for and found interaction effects between ADI and each demographic factor, with stronger ADI-morbid obesity association observed for patients that were female, Hispanic, non-Hispanic White and 40-65 years old. The highest ADI quintile also had a high prevalence (44 %) of any obesity (aOR, 2.2; 95 % CI = 2.1, 2.2). In geospatial mapping, areas with higher ADI were more likely to have higher proportion of patients with morbid obesity. Census-based measures, like the ADI, may be informative for area-level obesity reduction strategies as it can help identify neighborhoods at high odds of having patients with morbid obesity.

A cross-sectional study of organized activity participation and emotional wellbeing among non-immigrant and immigrant-origin children in British Columbia, Canada.

Organized activity participation has been linked to children's emotional wellbeing. However, a scarcity of literature considers the role of immigrant background. This study's primary objective was to measure the association between organized activity participation and emotional wellbeing among a population-based sample of Grade 7 children in British Columbia, Canada. We also examined whether this relationship depended on immigration background. Our sample included 14,406 children (47.8% female; mean age = 12.0 years). 9,393 (65.2%) children were of non-immigrant origin (48.9% female; mean age = 12.1 years). 5,013 children (34.8%) were of immigrant origin (45.8% female; mean age = 12.0 years; 40.8% first-generation). Participants completed the Middle Years Development Instrument, a self-report survey measuring children's wellbeing and assets. We used odds ratios and the χ2 test to compare the organized activity participation of non-immigrant and immigrant-origin children. We used multiple linear regression to measure associations between participation and indicators of emotional wellbeing and assessed whether associations varied based on immigrant background, controlling for demographic factors and peer belonging. Participation in any activity was similar among non-immigrant and immigrant-origin children (OR1st-gen=1.06, p=0.37; OR2nd-gen=0.97, p=0.62). Immigrant generation status modified the relationship between participation and emotional wellbeing (χSWL 2=3.69, p=0.03; χDep 2=12.31, p<0.01). Beneficial associations between participation and both life satisfaction and depressive symptoms were observed among non-immigrant children only, although associations were small. We conclude that immigrant background modestly modified the association between organized activity participation and emotional wellbeing.

Hepatitis B virus infection combined with nonalcoholic fatty liver disease: Interaction and prognosis.

Hepatitis B virus (HBV) infection is still one kind of the infectious diseases that seriously threaten human health. Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. HBV infection complicated with NAFLD is increasingly common. This review mainly describes the interaction between HBV infection and NAFLD, the interaction between steatosis and antiviral drugs, and the prognosis of HBV infection complicated with NAFLD. Most studies suggest that HBV infection may reduce the incidence of NAFLD. NAFLD can promote the spontaneous clearance of hepatitis B surface antigen (HBsAg), but whether it affects antiviral efficacy has been reported inconsistently. HBV infection combined with NAFLD can promote the progression of liver fibrosis, especially in patients with severe steatosis. The outcome of HBV infection combined with NAFLD predisposing to the progression of HCC remains controversial.

Vaccine confidence among those living with allergy during the COVID pandemic (ACCORD): A scoping review.

Background: Reports of allergic reactions to coronavirus disease 2019 (COVID-19) vaccines, coupled with an "infodemic" of misinformation, carry the potential to undermine confidence in the COVID-19 vaccines. However, no attempts have been made to comprehensively synthesize the literature on how allergic disease and fear of allergic reactions to the vaccines contribute to hesitancy. Objectives: Our aim was to review the academic and gray literature on COVID-19 vaccine hesitancy and allergic reactions. Methods: We searched 4 databases (CINAHL, PsycINFO, MEDLINE, and Embase) using a search strategy developed by content and methodologic experts. No restrictions were applied regarding COVID-19 vaccine type, country of study, or patient age. Eligible articles were restricted to 10 languages. Results: Of the 1385 unique records retrieved from our search, 60 articles (4.3%) were included. Allergic reactions to the COVID-19 vaccine were rare but slightly more common in individuals with a history of allergic disease. A fifth of the studies (13 of 60 [22%]) discussed vaccine hesitancy due to possibility of an allergic reaction. Additionally, the present review identified research on details of vaccine-related anaphylaxis (eg, a mean and median [excluding clinical trial data] of 12.4 and 5 cases per million doses, respectively) and allergic reactions (eg, a mean and median [excluding clinical trial data] of 489 and 528 cases per million doses, respectively). Conclusion: COVID-19 vaccine acceptance among individuals living with allergy and among those with no history of allergic disease may be affected by fear of an allergic reaction. Despite the low incidence of allergic reactions to the COVID-19 vaccine, fear of such reactions is one of the most commonly cited concerns reported in the literature.

Colorectal cancer screening barriers and facilitators among Jordanians: A cross-sectional study.

The factors affecting the adherence of Jordanians to colorectal cancer (CRC) screening remain underexplored. We examined the inhibitory and facilitating factors that influence the uptake of CRC screening among Jordanians. We conducted questionnaire interviews between April 2020 and June 2021 with 861 Jordanians aged 50-75. We analyzed the differences between proportions using the chi-square test. Binary logistic regression was conducted to determine factors associated with awareness of CRC and its screening. Of all participants, 41.7 % were aware of the necessity of screening for CRC, and 27.2 % were aware of at least one of the tests for CRC screening. However, only 17.2 % of participants underwent screening. In the multivariate analysis, participants with higher income (p-value < 0.001, odds ratio[OR] = 1.9, 95 % confidence interval [CI]: 1.4-2.7), higher level of education (p-value < 0.001, OR = 2.6, 95 % CI: 1.8-3.7), family history of colon cancer (p-value < 0.001, OR = 2.8, 95 % CI = 1.7-4.5), and those who had been screened for other cancers (p-value = 0.003, OR = 1.7, 95 % CI: 1.2-2.5) were more aware of the necessity of screening. Concerning barriers to screening, 'feeling well,' lack of physician endorsement, and difficult access to health care were the most commonly reported inhibitory factors (53.9 %, 52.3 %, and 31.9 %, respectively). The most commonly stated incentivizing factor was physician endorsement (82.3 %). Screening rates for CRC in eligible Jordanians remain low, albeit more than one-third of participants are aware of the necessity of screening. Enhanced awareness of barriers and incentivizing factors should help to prioritize national strategies to improve screening rates.

Infection prevention and control programme and COVID-19 measures: Effects on hospital-acquired infections in patients with cirrhosis.

Background & Aims: Bacterial infections affect survival of patients with cirrhosis. Hospital-acquired bacterial infections present a growing healthcare problem because of the increasing prevalence of multidrug-resistant organisms. This study aimed to investigate the impact of an infection prevention and control programme and coronavirus disease 2019 (COVID-19) measures on the incidence of hospital-acquired infections and a set of secondary outcomes, including the prevalence of multidrug-resistant organisms, empiric antibiotic treatment failure, and development of septic states in patients with cirrhosis. Methods: The infection prevention and control programme was a complex strategy based on antimicrobial stewardship and the reduction of patient's exposure to risk factors. The COVID-19 measures presented further behavioural and hygiene restrictions imposed by the Hospital and Health Italian Sanitary System recommendations. We performed a combined retrospective and prospective study in which we compared the impact of extra measures against the hospital standard. Results: We analysed data from 941 patients. The infection prevention and control programme was associated with a reduction in the incidence of hospital-acquired infections (17 vs. 8.9%, p <0.01). No further reduction was present after the COVID-19 measures had been imposed. The impact of the infection prevention and control programme remained significant even after controlling for the effects of confounding variables (odds ratio 0.44, 95% CI 0.26-0.73, p = 0.002). Furthermore, the adoption of the programme reduced the prevalence of multidrug-resistant organisms and decreased rates of empiric antibiotic treatment failure and the development of septic states. Conclusions: The infection prevention and control programme decreased the incidence of hospital-acquired infections by nearly 50%. Furthermore, the programme also reduced the prevalence of most of the secondary outcomes. Based on the results of this study, we encourage other liver centres to adopt infection prevention and control programmes. Impact and implications: Infections are a life-threatening problem for patients with liver cirrhosis. Moreover, hospital-acquired infections are even more alarming owing to the high prevalence of multidrug-resistant bacteria. This study analysed a large cohort of hospitalised patients with cirrhosis from three different periods. Unlike in the first period, an infection prevention programme was applied in the second period, reducing the number of hospital-acquired infections and containing multidrug-resistant bacteria. In the third period, we imposed even more stringent measures to minimise the impact of the COVID-19 outbreak. However, these measures did not result in a further reduction in hospital-acquired infections.
