The association of NT-proBNP levels in atrial fibrillation patients and 3-year risk of heart hospitalization and death

Abstract Background NT-proBNP-levels are often elevated in patients with atrial fibrillation (AF), but their clinical use and interpretation for predicting subsequent cardiovascular events has not been explored in an all-comers setting. Aim To determine whether NT-proBNP levels are associated with the risk of subsequent heart failure (CHF) and/or death in patients with AF and its relation to prior CHF diagnosis Method All patients with new-onset AF (defined by ICD-code I48) who had an NT-proBNP-level within +/- 14 days of the date of the AF date measured in a regional laboratory repository between 2000-2021 were included in the analysis cohort. Patients were categorized into NT-proBNP level (pg/mL) <1000, 1000-1999, ≥2000. If several NT-proBNP-levels were measured, the maximal value was used. The association between NT-proBNP level and the outcome CHF hospitalization and/or death within 3 years of diagnosis was assessed in Cox regression analyses adjusted for baseline characteristic and medications. Since there was an interaction (p<0.001) between Nt-proBNP-level and prior/new-onset CHF at time of AF diagnosis and no known CHF, two separate analyses were performed in patients with or new-onset CHF and those without prior CHF. Results There were 10559 patients with AF and no CHF, and 11 257 with AF and CHF. There were 14% of patients with new-onset CHF at time of new-onset AF diagnosis. These were grouped together with patients with known CHF. Patients with no prior CHF were younger (76 years (95% CI 68-83) vs 80 (72-87), p<0.001), and healthier with less often diabetes (18.4% vs 24.5%, p<0.001), prior myocardial infarction (12.0% vs 24.3%), a lower CHA2DS2-VASc score (3.0 vs 5.0, p<0.001) and a lower median NT-proBNP level (1650 pg/mL (95% CI 702-3549) vs 4240 pg/mL (2160-8860), p<0.001). Among patients with AF and no prior CHF, the incidence rate in the lowest NT-proBNP level was low, but increased with higher levels (Table). Adjusting for covariates and medications, the risk of both CHF hospitalization and CHF/death compared to the reference category NTproBNP< 1000 pg/mL was nearly 2 and 3 times higher among those who with initial NT-proBNP level 1000-1999 and ≥ 2000. Among patients with AF and known CHF, the incidence rate of CHF hospitalization or CHF hospitalization/death at the same NT-proBNP-strata was several times higher compared to patients without known CHF. Adjusting for covariates, the risk increased for CHF hospitalization or CHF/hospitalization similarly for each strata as for patients without known CHF. AF patients without known HF but with the highest elevation of NTproBNP-level had a risk of subsequent hospitalization of heart failure which was higher than those with known heart failure and lowest NTproBNP-level. Conclusion A higher NTproBNP-level in patients with AF identifies patients at higher risk of CHF hospitalization and/or death in both patients with no and prior CHF.Table

Relative effectiveness of high-dose vs. standard-dose quadrivalent influenza vaccine according to time of day of vaccination: a post-hoc analysis of the DANFLU-1 randomised clinical trial

Abstract Background Circadian variations have been shown to affect antibody response following vaccination. We sought to evaluate whether time of day of vaccination (ToV) modified the relative effectiveness of high-dose (QIV-HD) vs. standard-dose (QIV-SD) quadrivalent influenza vaccination, and further whether ToV was independently associated with hospitalisations and mortality. Methods This is a post-hoc analysis of the DANFLU-1 trial which was a randomized trial of QIV-HD vs. QIV-SD in adults aged 65-79 years conducted during the 2021-2022 influenza season. Vaccination took place between 7:05 AM and 8:08 PM. For this study, we stratified participants into early and late vaccination groups according to ToV before or after 11 AM, respectively. Prespecified outcomes included hospitalisations for pneumonia or influenza, respiratory disease, cardiovascular disease, and cardio-respiratory disease as well as all-cause hospitalisations and mortality. Hospitalisations were analysed as recurrent events using negative binomial regression, while mortality was analysed using Cox proportional hazard models, both of which were also used to test for interaction. For multivariable analysis, models were adjusted for baseline risk factors including sex, age, and multiple lung diseases. ToV was furthermore assessed as a continuous variable with 2-hour increments. Results In the final study population, the early group consisted of 5,371 (43%) participants (mean age 71.6±3.9 years, male sex 53.6%, QIV-SD 50.1%), while the late group consisted of 7,106 (57%) (mean age 71.8±4.0 years, male sex 52.4%, QIV-HD 49.9%). During follow-up, we observed 43 hospitalisations for pneumonia or influenza, 76 respiratory hospitalisations, and 62 mortalities. In recurrent event analysis, QIV-HD was associated with lower incidence of hospitalisation for pneumonia or influenza compared with QIV-SD irrespective of whether administered early (IRR 0.17 (95% CI 0.03-0.86), p=0.032) or late (IRR 0.37 (95% CI 0.16-0.88), p=0.024) (p-value for interaction = 0.69) (Figure 1). Effect estimates were consistent for all outcomes excluding cardiovascular hospitalisations regardless of early or late vaccination, and no effect modification was found (Figure 1). Interestingly, late vaccination was associated with higher incidence rate of respiratory hospitalisation (IRR 3.00 (95% CI 1.13-7.98), p=0.024, Figure 2), irrespective of vaccine type. The same association was found for ToV as a continuous variable (IRR 1.28 per 2-hour increment (95% CI 1.02-1.60), p=0.035). All above associations remained significant in multivariable analysis. Conclusion QIV-HD was associated with lower incidence of hospitalisation for pneumonia or influenza regardless of time of day for vaccination. In addition, later vaccination was associated with higher incidence of respiratory hospitalisation independent of vaccine type and known risk factors. Due to low power, however, this finding should be regarded as exploratory.Figure 1:Forest plotFigure 2:Incidence rates

Left ventricular ejection fraction and clinical outcomes after transcatheter aortic valve implantation

Abstract Background Reduced left ventricular ejection fraction (LVEF ≤50%) has been associated with poor prognosis in patients with severe aortic stenosis treated medically or with aortic valve replacement. However, less is known regarding the impact of different degrees of LVEF including moderately to severely reduced LVEF after transcatheter aortic valve replacement (TAVR). Purpose To examine the association between baseline LVEF and clinical outcomes after TAVR. Methods Patients undergoing TAVR between 2008-2021 from the Swedish Transcatheter Cardiac Intervention Registry (SWENTRY) were included. LVEF was estimated from echocardiography before TAVR and categorized as ≥50%, 40-49%, 30-39% and <30%. SWENTRY was linked to the National Patient Registry and Cause of Death Registry for outcome variables. Patients were followed for a median of 3.2 years for the primary outcome heart failure hospitalizations and the secondary outcome all-cause mortality. Cox regression analyses adjusted for age, sex, BMI, atrial fibrillation, eGFR class, diabetes, hypertension, frailty, chronic pulmonary disease and coronary artery disease were performed for the association between LVEF groups and outcome. Results In total, 8686 patients were included (mean age 81 years, 47% female) of whom 5904 (68%) patients had LVEF ≥50%, 1342 (15%) had LVEF 40-49%, 906 (10%) had LVEF 30-39% and 534 (6%) had LVEF <30%. Significant differences were observed across the LVEF groups in the cumulative incidence rates of heart failure hospitalizations (19, 30, 37 and 43%; p<0.001) and all-cause mortality (41, 54, 55, 57%; p<0.001) at five years. In adjusted analyses there was a stepwise increase in the risks of heart failure hospitalizations (Figure 1A) and all-cause mortality (Figure 1B) for each respective LVEF category. Conclusion Reduced LVEF, especially LVEF <30%, was associated with a dramatically increased long-term risk of heart failure hospitalizations and all-cause mortality in patients undergoing TAVR. LVEF should be considered in risk stratification and patient selection for TAVR.

Incidence and Risk of Coronavirus Disease 2019 Hospitalization Among Unvaccinated Children.

The aim of this study is to determine the incidence and risk factors associated with COVID-19 hospitalization among unvaccinated children. Children aged 0- < 18 years, members of Kaiser Permanente Northern California (KPNC), were followed from March 1, 2020, until the earliest occurrence of: chart-confirmed COVID-19 hospitalization, disenrollment from KPNC, age 18 years, receipt of COVID-19 vaccine, death, or study end (December 31, 2022). We calculated the incidence rate of hospitalization by SARS-CoV-2 variant period and by age group. We determined risk factors for hospitalization using Poisson regression. We also conducted descriptive analyses of hospitalized cases. Among 1,107,799 children, 423 were hospitalized for COVID-19 during follow-up. The incidence of hospitalization increased with each new SARS-CoV-2 variant and was highest among children aged < 6 months. Among the < 6-month-olds, the incidence rate per 100,000 person-months was 7 during predelta, 13.3 during delta, and 22.4 during omicron. Black (RR = 2.05, 95% CI: 1.33-3.16) and Hispanic children (RR = 1.82, 95% CI: 1.34-2.46) and children with any comorbidities were at high risk of hospitalization (RR = 3.81, 95% CI: 2.94-4.95). Overall, 20.3% of hospitalized children were admitted to an intensive care unit (ICU), but ICU admission was 36.1% among 12- < 18-year-olds. The majority of ICU admits (91.8%) had no comorbidities. Children too young to be vaccinated had the highest incidence of COVID-19 hospitalization, while adolescents had the highest proportion of ICU admissions. To prevent severe disease in children and adolescents, everyone eligible should be vaccinated.

Clinical and economic inpatient burden of respiratory syncytial virus (RSV) infections in children < 2 years of age in Germany, 2014-2019: a retrospective health claims analysis.

Respiratory syncytial virus (RSV) is a common cause for severe lower respiratory tract infections (LRTI) in children < 2 years of age in Germany - though little is known about the clinical and economic burden of RSV in children with and without risk factors per month of life. In a retrospective health claims analysis, we identified RSV inpatient cases between 2014 and 2019. We assessed incidence rates, mortality rate, healthcare resource utilization, associated direct costs per case and excess costs for 30, 90 and 365 days after hospital admission matched to a control group. The outcomes are reported separately for the first and second year of life (i.e., for infants and toddlers) and were stratified by month of life, preterm and risk status (i.e., presence of underlying disease: chronic respiratory or cardiac disease, immunosuppression, neurological diseases, diabetes, conditions originating in the perinatal period). RSV-attributable hospital incidence rate was higher in infants (30.25/1,000) than toddlers (14.52/1,000), highest in the first three months of life (44.21/1,000), in infants born preterm (64.76/1,000) or with any underlying disease (54.85/1,000). Mortality rate was also higher for infants (0.08/1,000) than toddlers (0.04/1,000). Mean 30-day excess costs ranged from 2,953 € for infants born full-term at no risk, hospitalized for 5 days, to 6,694 € for infants born extremely premature, hospitalized for 7 days. In Germany, the clinical and economic burden of RSV is substantial, especially in the most vulnerable population, that is, very young infants, those born premature and/or those with an underlying disease.

A Model-Based Estimation of RSV-Attributable Incidence of Hospitalizations and Deaths in Italy Between 2015 and 2019.

Respiratory syncytial virus (RSV) incidence is known to be underestimated in adults due to its infrequent diagnostic testing and lower sensitivity of single nasal/nasopharyngeal swab PCR testing outside of the early childhood period. RSV can trigger acute cardiac events as well as cause respiratory disease. Consequently, we used a model-based study to estimate RSV-attributable hospitalization and mortality incidence among adults in Italy between 2015 and 2019. Through a database predisposed by CREA Sanità, by extracting monthly data from the Italian hospitalization collection data of the Ministry of Health and the Italian National Institute of Statistics (ISTAT) data (mortality), we estimated yearly RSV-attributable incidence of events for different cardiorespiratory outcomes. We used a quasi-Poisson regression model, which accounted for periodic and aperiodic time trends and viral activity proxies. The yearly RSV-attributable cardiorespiratory hospitalization incidence increased with age and was highest among adults aged≥75 years (1064-1527 cases per 100,000 person-years). Similarly, the RSV-attributable cardiorespiratory mortality rate was highest among persons aged≥75 years (59-85 deaths per 100,000 person-years). Incidence rates for RSV-attributable hospitalizations and RSV-attributable mortality were on average 2-3 times higher for cardiorespiratory than respiratory disease alone. Incidence rate based on RSV-specific ICD codes only were 405-1729 times lower than modeled estimates accounting for untested events. RSV causes a substantial disease burden among adults in Italy and contributes to both respiratory and cardiovascular conditions. Our results emphasize the need for effective RSV prevention strategies, particularly among older adults.

Abstract MP24: Relationship of Socioeconomic Position on Incident Hypertension-related Hospitalization and Blood Pressure Control among participants in the Coronary Artery Risk Development in Young Adults (CARDIA)

Background: Hypertension hospitalization, defined as being admitted to the hospital with a primary diagnosis of hypertension, has been increasing among US adults. Individuals with low socioeconomic position have higher rates of uncontrolled blood pressure (BP). We evaluated the relationship of socioeconomic position on incident hypertension hospitalization and BP control rates following hospitalization. Methods: We analyzed data from CARDIA, a prospective cohort that enrolled 5,115 adults (2,637 self-identified Black and 2,478 White adults) 18 to 30 years old from 4 urban US areas in 1985-1986. Hypertension hospitalizations were ascertained by manual chart review over 34 years of annual follow-up. We compared the incidence rate of hypertension hospitalization and prevalence of uncontrolled BP, systolic/diastolic BP ≥140/90 mm Hg, at the study visit after hospitalization by socioeconomic position. Socioeconomic position included education, income, insurance status and neighborhood deprivation factor score at the last visit before hypertension hospitalization or last CARDIA visit attended for participants who were not hospitalized. Results: Overall, 67 CARDIA participants (1.3%) were hospitalized for hypertension. Participants hospitalized for hypertension had a median age of 47 years at time of hospitaliization, 51% were male, and 87% were Black. Among those hospitalized for hypertension, 12% had less than high school education, 44% had a family income &lt; $25,000, 30% were on Medicaid or Medicare, and 58% lived in a socially deprived neighborhood. The risk of hypertension hospitalization was higher for participants with less education and who lived in more socially deprived neighborhoods ( Table 1 ). At the first study visit following hospital discharge, 67% of participants had uncontrolled BP and there was no difference by socioeconomic position. Conclusion: The incidence rate of hypertension hospitalization was higher among people with low socioeconomic position. Uncontrolled BP was common following hypertension hospitalization.

Adult Respiratory Syncytial Virus Infection: Defining Incidence, Risk Factors for Hospitalization, and Poor Outcomes, a Regional Cohort Study, 2016-2022.

Respiratory syncytial virus (RSV) is a significant cause of illness in adults, especially older adults and those with underlying conditions. This study aimed to assess the incidence of RSV hospitalizations in adults and identify risk factors for hospitalization and poor outcomes. A retrospective cohort study was conducted using data from two hospitals in southern Israel from 2016-2022. We calculated incidence rates of RSV and influenza hospitalizations. Risk factors for hospitalization were analyzed using Poisson regression. We evaluated poor outcomes (death, ICU admission, or mechanical ventilation) among RSV-hospitalized patients. The median annual incidence of RSV hospitalization was 28.2/100,000 population, increasing with age to 199/100,000 in those ≥75 years. Significant risk factors for RSV hospitalization included pulmonary diseases (RR 4.2, 95% CI 3.4-5.2), cardiovascular diseases (RR 3.3, 95% CI 2.6-4.2), and chronic renal failure (RR 2.9, 95% CI 2.3-3.7). Among hospitalized RSV patients, 13.9% had poor outcomes. Renal failure (RR 1.81, 95% CI 1.23-2.66), neutropenia (RR 2.53, 95% CI 1.19-5.35), neutrophilia (RR 1.66, 95% CI 1.81-2.34), and lymphopenia (RR 2.03, 95% CI 1.37-3.0) were associated with poor outcomes. RSV causes a substantial burden of hospitalizations in adults, particularly among older adults and those with comorbidities. Identifying high-risk groups can help target prevention and treatment strategies, including vaccination.

The effect of Montreal's supervised consumption sites on injection-related infections among people who inject drugs: An interrupted time series.

Between June and November 2017, four supervised consumption sites (SCS) began operating in Montreal, Quebec. Earlier studies on SCS focused on examining their effects on blood-borne viral infections and overdose mortality. Our objective was to examine the effect of Montreal's SCS on the incidence, health service use and outcomes of injection-related infections (IRI) in people who inject drugs. We used Quebec's provincial administrative health data to identify people who inject drugs in Montreal and calculated the incidence of IRI in this population between December 2014 and December 2019. We conducted a retrospective, population-based interrupted time series to estimate the effect of Montreal's four SCS on the monthly incidence rates of IRI-related hospitalizations, emergency department (ED) visits, physician visits, and mortality. We also examined the effects of SCS on average length of IRI-related hospitalizations and incidence of hospitalizations involving surgery. The average age of Montreal's people who inject drugs was 41.84 years, and 66.41% were male. After the implementation of SCS, there was a positive level change in the incidence of hospitalizations (0.97; 95% confidence interval [CI]: 0.26, 1.68) for IRI. There was also a significant post-intervention decline in hospitalization trends (-0.05; 95% CI: -0.08, -0.02), with modest trend changes in ED visits (-0.02; 95% CI: -0.05, 0.02). However, post-intervention changes in level (0.72; 95% CI: -3.85, 5.29) and trend (0.06; 95% CI: -0.23, 0.34) for physician visits remained limited. SCS had no effect on the average length of hospitalizations, but there was a decreasing post-intervention trend in hospitalizations involving surgery (-0.03; 95% CI: -0.06, 0.00). Following the opening of the SCS, there was a moderate decline in the rate of hospitalizations to treat IRI, but the impact of the sites on the rate of physician visits remained limited. These findings suggest that SCS may mitigate the incidence of more serious and complicated IRI over time.

Association of anesthesia handovers with perioperative and short-term outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

BackgroundAnesthesiologists transition patient care to combat clinician fatigue and accommodate shift limitations. Studies exploring the association of increased handovers with patient outcomes have conflicting findings. Here, we investigate the association of anesthesia handovers with perioperative outcomes in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. MethodsPatients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy at a single institution from 2017 to 2022 were stratified by the number of anesthesia attending and nonattending (nurse anesthetist/resident) handovers (0–1 or ≥2). Primary outcomes were intensive care unit and hospital length of stay, in addition to 30-day serious morbidity. Logistic and negative binomial regression models were adjusted for covariates related to patient and case complexity. ResultsA total of 182 patients were included. Median operative time was 720 minutes (interquartile range, 540–900 minutes). Most cases had fewer than 2 attending handovers (n = 147, 81% vs ≥2 handovers n = 35, 19%) and 2 nonattending handovers (n = 120, 71% vs ≥2 handovers n = 53, 29%). In adjusted models, there were no differences in 30-day serious morbidity and intensive care unit or hospital length of stay between the attending handover groups (0–1 vs ≥2). Patients with ≥2 non-attending handovers had similar odds of 30-day serious morbidity compared with the 0–1 group (odds ratio, 1.613, 95% confidence interval, 0.733–3.550, P = .235), but a longer total hospital (incidence rate ratio, 1.301, 95% confidence interval, 1.071–1.579, P = .008) and intensive care unit length of stay (incidence rate ratio 1.548, 95% confidence interval, 1.038–2.049, P = .030). ConclusionsMultiple anesthesia handovers were not associated with an increased risk of serious morbidity for patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. However, increased handovers (≥2) between nonattending providers was associated with longer hospital and intensive care unit length of stays.

Impact of co-resident health and living alone on risk of hospital admission for people with Parkinson’s disease

BackgroundPeople with Parkinson's Disease (PwP) have a higher rate of hospitalisation compared to the general population. Little is known about the impact of having a co-resident and their health on hospitalisation rates of PwP. MethodsWe utilised Clinical Practice Research Datalink (CPRD) GOLD data (2010–2015) to identify PwP and co-residents. We classed either the fittest or youngest adult as the primary caregiver in each household. Caregiver health was classified by the Cambridge Multimorbidity Score (CMS), primary care utilisation and prescriptions. We calculated the hospitalisation (elective, emergency) incidence rate ratios (IRRs) for PwP who lived alone compared to those with a caregiver using negative binomial regression, and whether worse caregiver health predicted higher risk of admissions. ResultsWe identified 3254 PwP and 4007 family members. PwP who lived alone were less likely to have an elective admission (0.79; 95 % CI 0.69–0.91) and more likely to have an emergency admission (1.40; 95 % CI 1.70-1.54). Worse caregiver health, as measured by the CMS, was associated with an increased risk of emergency admission (IRR 1.35; 95 % CI 1.17–1.57), but this attenuated and was consistent with chance in the fully adjusted model (1.04; 95 % CI 0.95–1.13). No strong associations were seen between caregiver health and elective admissions. ConclusionPwP who live alone are at increased risk of emergency and less likely to have elective hospital admissions. It is important that health care providers support such people and ensure they receive equitable access to the potential benefits of elective procedures.

The Trends, Clinicopathological Features, and Treatment Outcomes of Patients with Prostate Cancer in Lokoja, Nigeria

Abstract Background: Prostate cancer (PCa) was the most common noncutaneous cancer among Nigerian men in 2020. Despite this high incidence, documented rates may be an underestimation. Objectives: This study aimed to determine the hospital incidence rate, trends, and characterise the clinicopathologic features, and treatment outcomes of patients with PCa in our institution. Materials and Methods: A 5-year retrospective review of patients managed for PCa at the Federal Teaching Hospital, Lokoja (FTHL), Nigeria, from 2016 to 2020. Medical abstraction was done on clinicopathologic features, treatment received, serum prostate specific antigen (PSA) at diagnosis, 3, and 7 months of androgen deprivation therapy (ADT). Data obtained were analysed using SPSS 25, and trends analysis of the annual incidence rate and number of patients with PCa in the period was done using joinpoint regression modelling. Results: Of 89 patients, 83 had complete medical records. The average annual hospital incidence rate was 174/100,000, and the mean age at diagnosis was 70.4 years. Locally advanced disease was found in 81.9% of patients, and tumours were ISUP grade groups 4 and 5 in 54.2% of patients. ADT was done in 62.6% of the patients, while 28.9% of the patients defaulted after diagnosis. The mean serum PSA was 71.9 ng/mL (7.7–156) at diagnosis and was 11.1 ng/mL (0.1–102) and 15.3 ng/mL at 3 and 7 months of ADT, respectively. Only 40.6% of the treated patients had a serum PSA ≤ 4 ng/mL at 7 months of ADT. Conclusions: Patients with PCa in FTHL, Nigeria, have mostly locally advanced disease at diagnosis. Over half have a high-grade pattern and fail to achieve a serum PSA ≤ 4 ng/mL after 7 months of ADT.

Mental Health Hospitalizations in Canadian Children, Adolescents, and Young Adults Over the COVID-19 Pandemic

The COVID-19 pandemic resulted in multiple socially restrictive public health measures and reported negative mental health impacts in youths. Few studies have evaluated incidence rates by sex, region, and social determinants across an entire population. To estimate the incidence of hospitalizations for mental health conditions, stratified by sex, region, and social determinants, in children and adolescents (hereinafter referred to as youths) and young adults comparing the prepandemic and pandemic-prevalent periods. This Canadian population-based repeated ecological cross-sectional study used health administrative data, extending from April 1, 2016, to March 31, 2023. All youths and young adults from 6 to 20 years of age in each of the Canadian provinces and territories were included. Data were provided by the Canadian Institute for Health Information for all provinces except Quebec; the Institut National d'Excellence en Santé et en Services Sociaux provided aggregate data for Quebec. The COVID-19-prevalent period, defined as April 1, 2020, to March 31, 2023. The main outcome measures were the prepandemic and COVID-19-prevalent incidence rates of hospitalizations for anxiety, mood disorders, eating disorders, schizophrenia or psychosis, personality disorders, substance-related disorders, and self-harm. Secondary measures included hospitalization differences by sex, age group, and deprivation as well as emergency department visits for the same mental health conditions. Among Canadian youths and young adults during the study period, there were 218 101 hospitalizations for mental health conditions (ages 6 to 11 years: 5.8%, 12 to 17 years: 66.9%, and 18 to 20 years: 27.3%; 66.0% female). The rate of mental health hospitalizations decreased from 51.6 to 47.9 per 10 000 person-years between the prepandemic and COVID-19-prevalent years. However, the pandemic was associated with a rise in hospitalizations for anxiety (incidence rate ratio [IRR], 1.11; 95% CI, 1.08-1.14), personality disorders (IRR, 1.21; 95% CI, 1.16-1.25), suicide and self-harm (IRR, 1.10; 95% CI, 1.07-1.13), and eating disorders (IRR, 1.66; 95% CI, 1.60-1.73) in females and for eating disorders (IRR, 1.47; 95% CI, 1.31-1.67) in males. In both sexes, there was a decrease in hospitalizations for mood disorders (IRR, 0.84; 95% CI, 0.83-0.86), substance-related disorders (IRR, 0.83; 95% CI, 0.81-0.86), and other mental health disorders (IRR, 0.78; 95% CI, 0.76-0.79). This cross-sectional study of Canadian youths and young adults found a rise in anxiety, personality disorders, and suicidality in females and a rise in eating disorders in both sexes in the COVID-19-prevalent period. These results suggest that in future pandemics, policymakers should support youths and young adults who are particularly vulnerable to deterioration in mental health conditions during public health restrictions, including eating disorders, anxiety, and suicidality.

Fungal Infections in Hospitalized Patients of Systemic Lupus Erythematosus: A United States Nationwide Cohort Analysis.

Introduction/objective Immunosuppressive therapy is the cornerstone of management in patients with systemic lupus erythematosus (SLE). Patients on immunosuppressive therapy are at increased risk of developing opportunistic fungal infections. We conducted this analysis to describe the epidemiology, including incidence, risk factors, and outcomes, of fungal infections in hospitalized patients with SLE in the United States. Method A retrospective cohort study was performed by analyzing the National Inpatient Sample (NIS) 2016-2020 for all patients with a discharge diagnosis of SLE and fungal infections, including histoplasmosis, pneumocystosis, cryptococcosis, aspergillosis, and blastomycosis, as a primary or secondary diagnosis via ICD-10 (International Classification of Diseases 10th Revision) codes. Frequencies, demographics, and trends were determined and compared between hospitalized patients with SLE and those without SLE. STATA version 17 was used for data analysis. A p-value of ≤0.05 was considered statistically significant. Results In hospitalized SLE patients, there were lower odds of developing fungal infections in females (odds ratio (OR): 0.63 (95% confidence interval (CI): 0.49-0.80)) and higher odds in Hispanic (OR: 1.52 (95% CI: 1.16-1.98) and Asian (OR: 1.78 (95% CI: 1.15-2.75) populations. Steroid use (OR: 1.96 (95% CI: 1.58-2.42)), concomitant HIV infection(OR: 22.39 (95% CI: 16.06-31.22)), and the presence of leukemias (OR: 3.56 (95% CI: 1.67-7.59)) and lymphomas (OR: 3.29 (95% CI: 1.78-6.09)) in hospitalized SLE patients were significant predictors of fungal infection (p < 0.01). There were differences in the incidence of fungal infections based on geographical areas in the US, with blastomycosis being more common in the Midwest. From 2016 to 2020, there was a decline in the incidence rate of hospitalization per 100,000 for non-SLE patientswith fungal infections (10.7 per 100,000 hospitalizations in 2016 versus 9.6 per 100,000 hospitalizations in 2020), whereas this rate remained steady for the SLE cohort (0.1 per 100,000 hospitalizations in 2016 versus 0.2 per 100,000 hospitalizations in 2020). Conclusions Hospitalized patients with SLE are at an increased risk of developing fungal infections, and this risk is increased further in patients who are males, are on steroid therapy, and have HIV or leukemia and lymphomas. Further studies can be done to explain the increased risk of fungal infections associated with these patient characteristics.

Retrospective Analysis of Clinical Characteristics and Disease Outcomes in Children and Adolescents Hospitalized Due to COVID-19 Infection in Tunisia

Due to low susceptibility of coronavirus disease of 2019 (COVID-19) in children, limited studies are available regarding COVID-19 in the pediatric population in Tunisia. The current study evaluated the incidence, clinical characteristics, and outcomes of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection among children hospitalized at Béchir Hamza Children’s Hospital. A retrospective cohort analysis was conducted using the hospital database between March 2020 and February 2022 with children aged ≤15 years with SARS-CoV-2 infection (confirmed by RT-PCR). A total of 327 COVID-19 hospitalized patients with a mean age of 3.3 years were included; the majority were male. Neurological disease (20%) was the most common comorbidity, while fever (95.3%) followed by cough (43.7%) and dyspnea (39.6%) were the most frequent symptoms reported. Severe disease with oxygen requirement occurred in 30% of the patients; 13% were admitted in the Intensive Care Unit. The overall incidence rate of COVID-19 hospitalization (in Tunis governorates) was 77.02 per 100,000 while the inpatient case fatality rate was 5% in the study population. The most prevalent circulating variant during our study period was Delta (48.8%), followed by Omicron (26%). More than 45% of the study population were &lt;6 months and one-fourth (n = 25, 26.5%) had at least one comorbidity. Thus, the study findings highlight the high disease burden of COVID-19 in infants.

Sex Differences in the Associations of Traditional Risk Factors and Incident Heart Failure Hospitalization: A Prospective Cohort Study of 102 278 Chinese General Adults.

Evidence regarding sex differences in the associations of traditional risk factors with incident heart failure (HF) hospitalization among Chinese general adults is insufficient. This study aimed to evaluate the potential sex differences in the associations of traditional risk factors with HF among Chinese general adults. Data were from a subcohort of the China PEACE (Patient-Centered Evaluative Assessment of Cardiac Events) Million Persons Project. The traditional risk factors were collected at baseline, and the study outcome was HF-related hospitalization identified from the Inpatients Registry. A total of 102 278 participants (mean age, 54.3 years; 39.5% men) without prevalent HF were recruited. A total of 1588 cases of HF-related hospitalization were captured after a median follow-up of 3.52 years. The incidence rates were significantly higher in men (2.1%) than in women (1.2%). However, the observed lower risk of HF in women was significantly attenuated or even vanished when several traditional risk factors were poorly controlled (P for sex-by-risk factors <0.05). The selected 11 risk factors collectively explained 62.5% (95% CI, 55.1-68.8) of population attributable fraction for HF in women, which is much higher than in men (population attributable fraction, 39.6% [95% CI, 28.5-48.9]). Although women had a lower incidence rate of hospitalization for HF than men in this study, the risk for HF increased more remarkably in women than in men when several traditional risk factors were poorly controlled. This study suggests that intensive preventative strategies are immediately needed in China.

COVID-19 pandemic and trends in clinical outcomes and medication use for patients with established atrial fibrillation: A nationwide analysis of claims data

Study objectiveThe COVID-19 pandemic disrupted multiple aspects of the health care system, including the diagnosis and control of chronic conditions. This study aimed to quantify pandemic-related changes in the rates of clinical events among patients with atrial fibrillation (AF). Design/setting/participantsIn this retrospective cohort study, we identified individuals with established AF at any time before 2019 using de-identified Optum's Clinformatics® Data Mart, and followed them from 3/18/2019 to death, or disenrollment, or the end of the study (09/30/2021). Main outcomeRates of clinical event, including all-cause hospitalization, ischemic stroke, and bleeding. We constructed interrupted time series to test changes in outcomes after the onset of the COVID-19 pandemic (3/11/2020, date of pandemic declaration). We then identified the first month after the start of the pandemic in which outcomes returned to pre-pandemic levels. ResultsA total of 561,758 patients, with a mean age of 77 ± 9.9 years, were included in the study. The monthly incidence rate of all-cause hospitalization decreased from 2.8 % in the period immediately before the pandemic declaration to 1.7 % in the period immediately after, with p-value for level change<0.001. The rate of new ischemic stroke diagnoses decreased from 0.28 % in the period immediately before pandemic declaration to 0.20 % in the period immediately after, and the rate of major bleeding diagnoses from 0.81 % to 0.59 %, both p-values for level change<0.01. The incidence rate of ischemic stroke and bleeding events returned to pre-pandemic levels in October and November 2020, respectively. ConclusionsThe COVID-19 pandemic was associated with a decrease in health care visits for ischemic stroke and bleeding in a nationwide cohort of patients with established AF.

Intersectional inequalities in paediatric infectious diseases: a national cohort study in Sweden

BackgroundIt is well known that socially deprived children are more likely to be hospitalised for infections. Less is known about how different social disadvantages interact. Therefore, we examine intersectional inequalities...

Clinical and economic burden of respiratory syncytial virus in children aged 0–5 years in Italy

BackgroundRespiratory syncytial virus (RSV) is among the leading causes of hospitalization due to lower respiratory tract infections (LRTIs) in children younger than 5 years worldwide and the second cause of infant death after malaria. RSV infection occurs in almost all the infants before the second year of life with variable clinical severity, often requiring medical assistance. This analysis investigated patients aged 0–5 years with RSV infection focusing on epidemiology, clinical features, and economic burden of RSV-associated hospitalizations in a setting of Italian real clinical practice.MethodsAn observational retrospective analysis was conducted on administrative databases of healthcare entities covering around 2.6 million residents of whom 120,000 health-assisted infants aged < 5 years. From 2010 to 2018, pediatric patients were included in the presence of hospitalization discharge diagnosis for RSV infections, and RSV-related acute bronchiolitis or pneumonia. Epidemiology, demographics, clinical picture and costs were evaluated in RSV-infected patients, overall and stratified by age ranges (0–1, 1–2, 2–5 years) and compared with an age-matched general population.ResultsOverall 1378 RSV-infected children aged 0–5 years were included. Among them, the annual incidence rate of RSV-related hospitalizations was 175–195/100,000 people, with a peak in neonates aged < 1 year (689–806/100,000). While nearly 85% of infected infants were healthy, the remaining 15% presented previous hospitalization for known RSV risk factors, like preterm birth, or congenital heart, lung, and immune diseases. The economic analysis revealed that direct healthcare costs per patient/year were markedly higher in RSV patients than in the general population (3605€ vs 344€).ConclusionsThese findings derived from the real clinical practice in Italy confirmed that RSV has an important epidemiological, clinical, and economic burden among children aged 0–5 years. While the complex management of at-risk infants was confirmed, our data also highlighted the significant impact of RSV infection in infants born at term or otherwise healthy, demonstrating that all infants need protection against RSV disease, reducing then the risk of medium and long-term complications, such as wheezing and asthma.
