A consistent finding from contemporary Western societies is that women outlive men. However, what is unclear is whether sex differences in survival are constant across varying socio-ecological conditions. We test the universality of the female survival advantage with mortality data from a nineteenth century population in the Baja California peninsula of Mexico. When examined simply, we find evidence for a male-biased survival advantage. However, results from Cox regression clearly show the importance of age intervals for variable survival patterns by sex. Our key findings are that males: (i) experience significantly lower mortality risk than females during the ages 15–30 (RR = 0.69), (ii) are at a significantly increased risk of dying in the 61+ category (RR = 1.30) and (iii) do not experience significantly different mortality risk at any other age interval (0–14, 31–45, 46–60). We interpret our results to stem from differing intrinsic and extrinsic risk factors for sex-biased mortality across age intervals, highlighting the relevance of a lifecourse approach to the study of survival advantage. Ultimately, our results make clear the need to more broadly consider variability in mortality risk factors across time and place to allow for a clearer understanding of human survival differences.

Objective: To investigate risk factors of disability pension (DP) in young adults diagnosed with ADHD in Sweden. Method: In total, 9718 individuals diagnosed with incident ADHD in young adult age (19–29 years) 2006 to 2011, were identified through national registers. They were followed for 5 years and Cox regression models were applied to analyze the DP risk (overall and by sex), associated with socio-demographics, work-related factors, and comorbid disorders. Results: Twenty-one percent of all received DP. Being younger at diagnosis (hazard ratio [HR] = 1.54; 95%confidence interval [CI] 1.39–1.71); low educational level (HR = 1.97; 95%CI 1.60–2.43 for <10 years); work-related factors at baseline (no income from work [HR = 2.64; 95%CI 2.35–2.98] and sickness absence >90 days [HR = 2.48; 95%CI2.17–2.83]); and schizophrenia/psychoses (HR = 2.16; 95%CI 1.66–2.80), autism (HR = 1.87; 95%CI 1.42–2.46), anxiety (HR = 1.34; 95%CI 1.22–1.49) were significantly associated with an increased risk of DP. Similar risk patterns were found in men and women. Conclusion: Work-related factors and comorbid mental disorders need to be highlighted in early vocational rehabilitation for individuals with ADHD.

Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008). Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008). Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

Statins reduce CVD events, LDL cholesterol (LDL-C) and triglycerides, with an increased risk of diabetes. The underlying predictors of statin-associated diabetes are unclear. We evaluated lipoprotein subclass and size changes in response to rosuvastatin to identify predictors of diabetes on statin therapy Among 11,918 non-diabetic participants in JUPITER (NCT00239681), lipoprotein subclasses and size were quantified by NMR spectroscopy (LipoScience, NC) prior to and 1 year after randomization to placebo or rosuvastatin (total 370 incident diabetes). Cox regression models were adjusted for diabetes risk factors Compared to baseline, rosuvastatin lowered LDL-C and particles by lowering cholesterol-enriched large LDL (58%) and IDL (46%), with less relative lowering of cholesterol-poor small LDL (22%), resulting in smaller LDL size (1.5%). Rosuvastatin lowered (15%-20%) triglycerides, VLDL triglycerides, and VLDL particles by lowering large (15%), medium (7%), and small (27%) particles, and increasing VLDL size (3%) (all p<0.0001). Among statin-allocated individuals, after adjusting for typical risk factors, incident diabetes was inversely associated with baseline levels of LDL-C, HDL-C, large LDL particles, and LDL size, and positively associated with baseline triglycerides, non-HDL-C, ApoB, LDL particles, VLDL particles, VLDL triglycerides and size (Table). Similar associations were seen in on-treatment rosuvastatin and placebo groups In JUPITER, random allocation to rosuvastatin altered the lipoprotein subclass profile in a manner associated with the development of diabetes Adjusted Hazard Ratios (95% CI) and Risk of Incident Diabetes with Rosuvastatin Baseline parameters HR per 1-SD p value LDL-C .86 (0.76-0.98) .02 HDL-C .69 (0.54-0.87) .002 Triglycerides 1.62 (1.41-1.86) <.0001 Non-HDL-C 1.20 (1.04-1.39) .01 ApoB 1.35 (1.18-1.55) <.0001 Total LDL* 1.32 (1.15-1.51) <.0001 Large LDL* .79 (0.71-0.87) <.0001 Small LDL* 1.71 (1.40-2.08) <.0001 IDL* .97 (0.85-1.11) .69 LDL size .66 (0.58-0.75) <.0001 Total VLDL* 1.16 (1.00-1.34) .046 Large VLDL* 1.78 (1.51-2.10) <.0001 Medium VLDL* 1.35 (1.15-1.58) .0002 Small VLDL* .93 (0.82-1.06) .30 VLDL size 1.58 (1.39-1.80) <.0001 VLDL triglycerides 1.51 (1.31-1.73) <.0001 *particles

Abstract Background The relationship between common patient characteristics, such as sex and metabolic comorbidities, and mortality from COVID-19 remains incompletely understood. Emerging evidence suggests that metabolic risk factors may also vary by age. This study aimed to determine the association between common patient characteristics and mortality across age-groups among COVID-19 inpatients. Methods We performed a retrospective cohort study of patients discharged from hospitals in the Premier Healthcare Database between April – June 2020. Inpatients were identified using COVID-19 ICD-10-CM diagnosis codes. A priori-defined exposures were sex and present-on-admission hypertension, diabetes, obesity, and interactions between age and these comorbidities. Controlling for additional confounders, we evaluated relationships between these variables and in-hospital mortality in a log-binomial model. Results Among 66,646 (6.5%) admissions with a COVID-19 diagnosis, across 613 U.S. hospitals, 12,388 (18.6%) died in-hospital. In multivariable analysis, male sex was independently associated with 30% higher mortality risk (aRR, 1.30, 95% CI: 1.26 – 1.34). Diabetes without chronic complications was not a risk factor at any age (aRR 1.01, 95% CI: 0.96 – 1.06), and hypertension without chronic complications was only a risk factor in 20-39 year-olds (aRR, 1.68, 95% CI: 1.17 – 2.40). Diabetes with chronic complications, hypertension with chronic complications, and obesity were risk factors in most age-groups, with highest relative risks among 20-39 year-olds (respective aRRs 1.79, 2.33, 1.92; p-values ≤ 0.002). Conclusions Hospitalized men with COVID-19 are at increased risk of death across all ages. Hypertension, diabetes with chronic complications, and obesity demonstrated age-dependent effects, with the highest relative risks among adults aged 20-39.

Abstract Background Although hemodialysis (HD) adequacy, single-pool Kt/Vurea (spKt/V), is inversely correlated with body size, each is known to affect patient survival in the same direction. Therefore, we sought to examine the relationship between HD adequacy and mortality according to body mass index (BMI) in HD patients and explore a combination effect of BMI and HD adequacy on mortality risk. Methods We retrospectively reviewed patient data from the Korean Society of Nephrology registry, a nationwide database of medical records of HD patients, from January 2001 to June 2017. We included patients ≥18 years old who were receiving maintenance HD. Patients were categorized into three groups according to baseline BMI (< 20 (low), 20 to < 23 (normal), and ≥ 23 (high) kg/m2). Baseline spKt/V was divided into six categories. Results Among 18,242 patients on HD, the median follow-up duration was 5.2 (IQR, 1.9–8.9) years. Cox regression analysis showed that, compared to the reference (spKt/V 1.2–1.4), lower and higher baseline spKt/V were associated with greater and lower risks for all-cause mortality, respectively. However, among patients with high BMI (n = 5588), the association between higher spKt/V and lower all-cause mortality was attenuated in all adjusted models (Pinteraction < 0.001). Compared to patients with normal BMI and spKt/V within the target range (1.2–1.4), those with low BMI had a higher risk for all-cause mortality at all spKt/V levels. However, the gap in mortality risk became narrower for higher values of spKt/V. Compared to patients with normal BMI and spKt/V in the target range, those with high BMI and spKt/V < 1.2 were not at increased risk for mortality despite low dialysis adequacy. Conclusions The association between spKt/V and mortality in HD patients may be modified by BMI.

Background: It is currently unknown if premature atrial contractions (PACs) detected on the routine screening electrocardiogram are associated with an increased risk of ischemic stroke. Methods: We examined the association between PACs and ischemic stroke in 22,975 (mean age 64 ± 9.2; 56% women; 40% black) participants from the Reasons for Geographic and Racial Differences in Stroke study. Participants who were free of stroke at baseline were included. PACs were detected from centrally read electrocardiograms at baseline. Cox regression was used to examine the association between PACs and ischemic stroke events through March 31, 2014. Results: PACs were present in 1,687 (7.3%) participants at baseline. In a Cox regression model adjusted for stroke risk factors and potential confounders, PACs were associated with an increased risk of ischemic stroke (hazards ratio (HR) 1.34, 95% CI 1.04-1.74). The relationship was limited to non-lacunar infarcts (HR 1.42, 95% CI 1.08-1.87), and not lacunar strokes (HR 1.01, 95% CI 0.51-2.03). An interaction by sex was detected, with the association between PACs and ischemic stroke being stronger among women (HR 1.82, 95% CI 1.29-2.56) than men (HR 1.03, 95% CI 0.69-1.52; p-interaction = 0.0095). Conclusion: PACs detected on the routine electrocardiogram are associated with an increased risk for non-lacunar ischemic strokes, especially in women.

Introduction: Substance and opioid misuse present significant illness burdens in Emergency Departments (EDs). Understanding risk factors for mortality in these patients is urgently needed to allow targeted prevention. This studys objective was to determine whether frequent ED use is independently associated with mortality among patients with substance and opioid misuse, and secondarily, whether degree of frequent use influences mortality risk. Methods: This is a retrospective cohort study in Alberta, Canada. National Ambulatory Care Reporting System ED data was linked to Vital Statistics mortality data using postal code, birthdate, and sex. All adults (18 years old at index visit, i.e. first visit made in the study year) with substance or opioid misuse (defined by ICD-10 codes) from April 1, 2012 to March 31, 2013 were included. Frequent use was defined by 5 ED visits in the 12 months prior to index visit. The primary outcome was mortality within 90 days, and secondarily, within 30 days, 365 days, and 2 years post-index visit. Mortality was compared using Kaplan-Meier curves and Cox regression adjusting for age, sex and income. Degree was examined by subcategorizing frequent use into 5-10, 11-15, 16-20, and >20 visits. Results: Overall, 16,389 patients made 24,880 visits for substance misuse, and 1787 patients made 2241 visits for opioid misuse. Frequent vs. non-frequent substance misusers were older, more often female, lower income, more often of rural residence, and arrived more by ambulance for lower acuity visits that were hospitalized less often. Compared to frequent substance misusers, frequent opioid misusers were more often female, of non-rural residence, arrived less often by ambulance, and made higher acuity visits that were hospitalized more often. Among substance misuse patients, 97.1% (95% CI: 96.6, 97.7) of frequent users vs. 98.0% (95% CI: 97.7, 98.2) of non-frequent users were alive at 2 years. Frequent use was significantly associated with mortality at 365 days (HR 1.36 [95% CI: 1.04, 1.77]) and 2 years (HR 1.32 [95% CI: 1.04, 1.67]) but not at 90 or 30 days. Subcategorized by degree, frequent use was significantly associated with mortality only for patients with >20 visits/year at 365 days (HR 1.88 [1.03, 3.44]) and 2 years (HR 1.89 [1.10, 3.22]). Among opioid misuse patients, there was no difference in mortality between frequent and non-frequent ED users at any time point. However, subcategorized by degree, a significant association was seen for those with 16-20 visits/year at 365 days (HR 3.62 [95% CI:1.13, 11.66]), and 2 years (HR 3.37 [95% CI: 1.05, 10.81]). Conclusion: In substance misuse patients, frequent ED use was significantly associated with long-term but not short-term mortality. Mortality risk for substance and opioid misuse patients was concentrated in extremely frequent users suggesting that the highest frequency presenters should be targeted for prevention.

This study examined the association between lifestyle risk factors and all-cause and cardiovascular disease (CVD) mortality in 9945 Korea adults (56% women) aged 45 years and older. Smoking, heavy alcohol intake, underweight or obesity, physical inactivity, and unintentional weight loss (UWL) were included as risk factors. During 9.6 ± 2.0 years of follow-up, there were a total of 1530 cases of death from all causes, of which 365 cases were from CVD. Compared to a zero risk factor (hazard ratio, HR = 1), the crude HR of all-cause mortality was 1.864 (95% CI, 1.509–2.303) for one risk factor, 2.487 (95% confidence interval, CI, 2.013–3.072) for two risk factors, and 3.524 (95% CI, 2.803–4.432) for three or more risk factors. Compared to a zero risk factor (HR = 1), the crude HR of CVD mortality was 2.566 (95% CI, 1.550–4.250) for one risk factor, 3.655 (95% CI, 2.211–6.043) for two risk factor, and 5.416 (95% CI, 3.185–9.208) for three or more risk factors. The HRs for all-cause and CVD mortality remained significant even after adjustments for measured covariates. The current findings showed that five lifestyle risk factors, including smoking, at-risk alcohol consumption, underweight/obesity, physical inactivity, and UWL, were significantly associated with an increased risk of all-cause and CVD mortality in Korean adults.

Abstract Aims Whether pulmonary artery (PA) dimension and coronary artery calcium (CAC) score, as assessed by chest computed tomography (CT), are associated with myocardial injury in patients with coronavirus disease 2019 (COVID-19) is not known. The aim of this study was to explore the risk factors for myocardial injury and death and to investigate whether myocardial injury has an independent association with all-cause mortality in patients with COVID-19. Methods and Results This is a single-centre cohort study including consecutive patients with laboratory-confirmed COVID-19 undergoing chest CT on admission. Myocardial injury was defined as high-sensitivity troponin I &gt;20 ng/L on admission. A total of 332 patients with a median follow-up of 12 days were included. There were 68 (20.5%) deaths; 123 (37%) patients had myocardial injury. PA diameter was higher in patients with myocardial injury compared with patients without myocardial injury [29.0 (25th–75th percentile, 27–32) mm vs. 27.7 (25–30) mm, P &lt; 0.001). PA diameter was independently associated with an increased risk of myocardial injury [adjusted odds ratio 1.10, 95% confidence interval (CI) 1.02–1.19, P = 0.01] and death [adjusted hazard ratio (HR) 1.09, 95% CI 1.02–1.17, P = 0.01]. Compared with patients without myocardial injury, patients with myocardial injury had a lower prevalence of a CAC score of zero (25% vs. 55%, P &lt; 0.001); however, the CAC score did not emerge as a predictor of myocardial injury by multivariable logistic regression. Myocardial injury was independently associated with an increased risk of death by multivariable Cox regression (adjusted HR 2.25, 95% CI 1.27–3.96, P = 0.005). Older age, lower estimated glomerular filtration rate, and lower PaO2/FiO2 ratio on admission were other independent predictors for both myocardial injury and death. Conclusions An increased PA diameter, as assessed by chest CT, is an independent risk factor for myocardial injury and mortality in patients with COVID-19. Myocardial injury is independently associated with an approximately two-fold increased risk of death.

Summary The main curative treatment modality for esophageal cancer is resection. Patients initially deemed suitable for resection may become unsuitable, most commonly due to signs of generalized disease or having become unfit for surgery. The aim was to assess risk factors for abandoning esophagectomy and its impact on survival. All patients diagnosed with an esophageal or gastroesophageal junction cancer in the Swedish National Register for Esophageal and Gastric Cancer from 2006–2016 were included and risk factors associated with becoming ineligible for resection were analyzed in multivariable logistic regression analysis. Overall survival was explored by multivariable Cox regression models. Among 1,792 patients planned for resection, 189 (11%) became unsuitable for resection before surgery and 114 (6%) had exploratory surgery without resection. Intermediate and high educational levels were associated with an increased probability of resection (odds ratio (OR) 1.46, 95% CI 1.05–2.05, OR 1.92, 95% CI 1.28–2.87, respectively) as was marital status (married: OR 1.37, 95% CI 1.01–1.85). Clinically advanced disease (cT4: OR 0.38, 95% CI 0.16–0.87; cN3: OR 0.27, 95% CI 0.09–0.81) and neoadjuvant treatment were associated with a decreased probability of resection (OR 0.62, 95% CI 0.46–0.88). Five-year survival for non-resected patients was only 4.5% although neoadjuvant treatment was associated with improved survival (HR 0.75, 95% CI 0.56–0.99). Non-resected patients with squamous cell carcinoma had comparatively reduced survival (HR 1.64, 95% CI 1.10–2.43). High socioeconomic status was associated with an increased probability of completing the plan to resect whereas clinically advanced disease and neoadjuvant treatment were independent factors associated with increased risk of abandoning resectional intent.
