Sex-related Differences In Outcomes Research Articles

Impact of Sex Differences on Clinical Outcomes in Patients Following Primary Revascularization for Acute Myocardial Infarction - Insights From the Japanese Nationwide Registry.

Women with acute myocardial infarction (AMI) often present a worse risk profile and experience a higher rate of in-hospital mortality than men. However, sex differences in post-discharge prognoses remain inadequately investigated. We examined the impact of sex on 1-year post-discharge outcomes in patients with AMI undergoing percutaneous coronary intervention.Methods and Results: We extracted patient-level data for the period January 2017-December 2018 from the J-PCI OUTCOME Registry, endorsed by the Japanese Association of Cardiovascular Intervention and Therapeutics. One-year all-cause and cardiovascular mortality and major adverse cardiovascular events were compared between men and women. In all, 29,856 AMI patients were studied, with 6,996 (23.4%) being women. Women were significantly older and had a higher prevalence of comorbidities than men. Crude all-cause mortality was significantly higher among women than men (7.5% vs. 5.4% [P<0.001] for ST-elevation myocardial infarction [STEMI]; 7.0% vs. 5.2% [P=0.006] for non-STEMI). These sex-related differences in post-discharge outcomes were attenuated after stratification by age. Multivariate analysis demonstrated an increase in all-cause mortality in both sexes with increasing age and advanced-stage chronic kidney disease (CKD). Within this nationwide cohort, women had worse clinical outcomes following AMI than men. However, these sex-related differences in outcomes diminished after adjusting for age. In addition, CKD was significantly associated with all-cause mortality in both sexes.

Sex-related differences in outcome of thoracic aortic surgery.

Sex-related dissimilarities' influence on outcomes following thoracic aortic surgery is poorly understood. Our aim is to examine sex-related disparities in patients undergoing thoracic aortic aneurysm (TAA). A total of 455 cases undergoing thoracic aortic aneurysm (TAA) surgery were consecutively enrolled between December 2009 and December 2015 in a Chinese hospital. Primary outcomes, including overall mortality and related risk factors, were evaluated. Cox regression is utilized to recognize the independent risk factor of these consequences. Females, compared to males, had greater indexed aortic diameters and higher aortic transvalvular pressure differences. For the location of aortic aneurysms, females had a higher rate of aortic arch involvement, while males had a higher rate of root involvement. Females underwent less frequent complex proximal aortic operations compared with males (29.5% versus 46.9%; p < 0.001). Women and men both had a lower rate of aortic transvalvular pressure difference and LV volume index 7 days after thoracic aortic surgery. The overall mortality for the women's groups (11%) was suggestively greater compared to 4.9% for the men's groups (p = 0.026). Renal failure and aortic arch involvement were the main risk factors associated with males' survival, while maximum indexed aortic diameter and cross-clamp time were the risk factors associated with females' survival. The outcome after TAA surgery was less favorable in women with significantly increased overall mortality. It highlights the need to focus on implementing personalized surgery strategies and gender-specific guidelines in treating female patients following TAA surgery.

Age and sex-related differences in outcomes of OHCA patients after adjustment for sex-based in-hospital management disparities

ObjectivesOut-of-hospital cardiac arrest (OHCA) survival differences due to sex remain controversial. Previous studies adjusted for prehospital variables, but not sex-based in-hospital management disparities. We aimed to investigate age and sex-related differences in survival outcomes in OHCA patients after adjustment for sex-based in-hospital management disparities. MethodsThis retrospective observational study used a prospective multicenter OHCA registry to review data of patients from October 2015 to December 2020. The primary outcome was good neurological outcome defined as cerebral performance category score 1 or 2. We performed multivariable logistic regression and restricted cubic spline analysis according to age. ResultsTotally, 8988 patients were analyzed. Women showed poorer prehospital characteristics and received fewer coronary angiography, percutaneous coronary interventions, targeted temperature management, and extracorporeal membrane oxygenation than men. Good neurological outcomes were lower in women than in men (5.8% vs. 12.2%, p < 0.001). After adjustment for age, prehospital variables, and in-hospital management, women were more likely to have good neurological outcomes than men (adjusted odds ratio [aOR] 1.37, 95% confidence interval [CI] 1.07–1.74, p = 0.012). The restricted cubic spline curve showed a reverse sigmoid pattern of adjusted predicted probability of outcomes and dynamic associations of sex and age-based outcomes. ConclusionsWomen with OHCA were more likely to have good neurological outcome after adjusting for age, prehospital variables, and sex-based in-hospital management disparities. There were non-linear associations between sex and survival outcomes according to age and age-related sex-based differences.

Sex-Related Differences in Patient Characteristics, Hemodynamics, and Outcomes of Cardiogenic Shock: INOVA-SHOCK Registry.

Little is known about sex-related differences in outcomes of patients with cardiogenic shock (CS) treated within a standardized team-based approach (STBA). We evaluated 520 consecutive patients (151 women and 369 men) with CS due to acute myocardial infarction (AMI) and heart failure (HF) in a single-center registry (January 2017-December 2019) and examined outcomes according to sex and CS phenotype. The primary outcome was in-hospital mortality. Secondary outcomes included major adverse cardiac events, 30-day mortality, major bleeding, vascular complications, and stroke. Women with AMI-CS had higher baseline acuity (CardShock score: female [F]: 5.5 vs male [M]: 4.0; P = .04). Women with HF-CS more often presented with cardiac arrest (F: 12.4% vs M: 2.4%; P< .01) and had higher rates of vasopressor use (F: 70.8% vs M: 58.0%; P = .04) and mechanical circulatory support (F: 46.1% vs M: 32.5%; P = .04). There were no sex-related differences in in-hospital mortality for AMI-CS (F: 45.2% vs M: 36.9%; P = .28) and HF-CS (F: 28.1% vs M: 24.5%; P = .56). Women with HF-CS experienced higher rates of major bleeding (F: 25.8% vs M: 13.7%; P = .02) and vascular complications (F: 15.7% vs M: 6.1%; P = .01). However, female sex was not an independent predictor of these complications. No sex differences in survival were noted at 1 year. Within an STBA, although women with AMI-CS and HF-CS presented with higher acuity, they experienced similar in-hospital mortality, major adverse cardiac events, 30-day mortality, stroke, and 30-day readmissions as men. Further research is needed to better understand the extent to which historical differences in CS outcomes can be mitigated by an STBA.

Impact of sex on ventral hernia repair outcomes: A systematic review and meta-analysis

BackgroundGiven the variability in abdominal physiology and hernia presentation between sexes, better comprehension of sex-related differences in outcomes would tailor surgical approach and counseling regarding postoperative outcomes. This meta-analysis aims to appraise the effect of sex on the outcomes of ventral hernia repair. MethodsA literature search in PubMed, EMBASE and Cochrane selected studies comparing outcomes of ventral hernia repair between sexes. Postoperative outcomes were assessed by pooled and meta-analysis. Statistical analysis was performed using RevMan 5.4. ResultsWe screened 3128 studies, reviewed 133, and included 18 observational studies, which encompassed 220,799 patients following ventral hernia repair. Postoperative chronic pain was significantly higher in female (OR 1,9; 95% CI 1,64–2,2; p ​< ​0,001). There were no significant differences in complications, readmission, or recurrence rates between females and males. ConclusionFemale sex is associated with a higher risk of postoperative chronic pain following ventral hernia repair.

Sex-dependent outcomes of recanalization-treated acute ischemic stroke patients at Shamir (Assaf Harofeh) medical center, Israel, 2011–2020

Background/objectivesSex-based differences in incidence, etiologies, severity and recanalization treatment outcomes of patients with acute ischemic stroke (AIS) have been studied extensively. We set out to determine if there were sex-based differences in outcomes among AIS patients who received recanalization treatments at Shamir (Assaf Harofeh) Medical Center (SMC), Israel, between 2011 and 2020. MethodsThis was a single-center, retrospective chart review. The primary analysis compared outcomes for men and women, overall and stratifying by disease severity. We compared also demographics, risk factors and workflow data. ResultsEight hundred and eleven patients received recanalization treatment between 2011 and 2020: 472 (58.1%) men and 339 (41.8%) women. Mean age, NIHSS score and proportion with an NIHSS score ≥ 6 were higher for women. Cerebrovascular risk factors were more prevalent in women, particularly atrial fibrillation, except that current smoking was more prevalent in men. Six hundred and twenty patients (78.1%) were treated with TPA alone, 89 (11.2%) with TPA and endovascular treatment (EVT), and 85 (10.7%) with EVT alone. Fifty percent of patients were discharged home, 41% to a rehabilitation hospital or nursing home, and 9% did not survive. Twenty-four patients (3%) sustained symptomatic bleeds. Outcomes were worse in patients with NIHSS score ≥ 6. Outcomes did not differ by sex. ConclusionsWhile treated women presented with more severe AIS and more risk factors, we did not find significant sex-related differences in outcomes. Meticulous adherence to risk factor modification remains the best strategy to reduce stroke incidence, morbidity, and mortality in women and in men.

Females experience elevated early morbidity and mortality but similar midterm survival compared to males after branched/fenestrated endovascular aortic aneurysm repair

ObjectiveThe objective of this study was to identify sex-related differences in outcomes following branched and/or fenestrated endovascular aortic repair (B/FEVAR) for thoracoabdominal (TAAA) and juxtarenal (JRAA) aortic aneurysms. MethodsChart review completed on 242 B/FEVAR patients (57 female; 23.5%) between 2007 and 2020 at a single center. Median follow-up time was 3.3 years (interquartile range [IQR], 1.6-5.3 years). ResultsNo statistically significant differences in age (females, 75.9 ± 5.4 years vs males, 74.7 ± 7.2 years; P = .162) or aneurysm size (64.9 ± 6.8 vs 65.8 ± 9.4 mm; P = .41) at presentation were observed between sexes. Females presented with fewer JRAAs (45.6% vs 73%; P < .001) and received more Crawford extent II (26.3% vs 10.8%; P =.004) TAAA coverage. Increased incidence of moderate/severe target vessel stenosis (29.8% vs 14%; P = .022) was observed in female patients. Intraoperatively, females had higher procedure times (530 [IQR, 425-625] vs 420 [IQR, 350-510] minutes; P < .001), fluoroscopy times (124.1 ± 49 vs 107.3 ± 43.5 minutes; P = .017), and contrast usage (200 [IQR, 150-270] vs 175 [IQR, 130-225] mL; P = .005). Unplanned intraoperative maneuvers (45.6% vs 28.1%; P = .043), graft delivery issues (24.6% vs 4.9%; P < .001), and additional intraoperative complications (61.4% vs 35.7%; P < .001) were also increased in females. Postoperatively, females had a longer intensive care unit (3 [IQR, 1-5] vs 1 [IQR, 1-3] days; P = .002) and hospital stay (8 [IQR, 5-13] vs 5 [IQR, 3-9] days; P < .001) and experienced increased rates of spinal cord ischemia (15.8% vs 3.8%; P = .001) and bowel ischemia (10.5% vs 2.7%; P = .013). In-hospital mortality (12.3% vs 2.7%; P = .004) was higher in female patients but midterm (6-year) survival was 60.2% for all patients (95% confidence interval, 53.0%-68.5%) and was similar between sexes (hazard ratio, 0.95; P = .83), which were the primary endpoints. No sex differences in midterm follow-up reintervention, endoleak, and rupture rates were observed. ConclusionsFemales experienced significantly higher B/FEVAR intraoperative times, complications, and in-hospital morbidity and mortality compared with males but similar midterm outcomes. Anatomic and atherosclerotic differences may have contributed to the observed in-hospital differences.

Abstract 9972: Sex-Related Differences and the Influence of Pregnancy on Cardiac Outcomes in Adults With a Systemic Right Ventricle and Biventricular Physiology

Introduction: Transposition of the great arteries (TGA) with a systemic right ventricle (sRV) and biventricular physiology is associated with increased morbidity and mortality. There is a paucity of data regarding sex-related differences in outcomes in the context of a sRV. Moreover, pregnancy has been associated with deterioration of sRV function in short-term post-partum follow-up, but the long-term impact remains largely unknown. Methods and Results: A retrospective cohort study was conducted on 214 adults, age 44.7±12.3 years, with a sRV and biventricular physiology followed for a median of 13 years at an adult congenital heart disease center. No sex-related difference was identified in the prevalence of atrial or ventricular arrhythmias, permanent pacemaker implantation, hospitalization for heart failure, systemic atrio-ventricular valve intervention, heart transplant, or cardiac death. Among the 82 (38.3%) women, age 44.0±12.5 years, 43 (52.4%) had at least one full-term pregnancy. Women had a lower prevalence of moderate to severe sRV dysfunction than men (21% vs 42.6%, p=0.001) despite similar ages. Beta-blockers (p=0.008), furosemide (p=0.012), and mineralocorticoid receptor antagonists (p=0.028) were less frequently prescribed to women than men. Women had fewer implantable cardioverter-defibrillators (ICDs) for primary prevention than men (3.7% vs 13.6%, p=0.016), with no difference in the prevalence of secondary prevention ICDs (1.2% vs 2.3%, p=1). The four women with a prohibitive maternal mortality risk (modified WHO class IV) complied with recommendations to avoid pregnancy. After excluding these 4 women, no differences regarding frequency of adverse cardiac events, age at the time of event, and proportion with moderate or severe sRV dysfunction were observed in women with (N=43) and without (N=35) pregnancies during 14 years of follow-up. Conclusions: Women with TGA and a sRV had a lower prevalence of moderate to severe systemic ventricular dysfunction than men, along with a lower proportion of primary prevention ICDs. Following risk assessment and counselling with contraindication of pregnancy in the highest risk subgroup, pregnancy had no impact on long-term cardiac outcomes.

SEX-RELATED DIFFERENCES AND THE INFLUENCE OF PREGNANCY ON CARDIAC OUTCOMES IN ADULTS WITH A SYSTEMIC RIGHT VENTRICLE AND BIVENTRICULAR PHYSIOLOGY

Transposition of the great arteries (TGA) with a systemic right ventricle (sRV) and biventricular physiology is associated with increased morbidity and mortality. There is a paucity of data regarding sex-related differences in outcomes in the context of a sRV. Moreover, pregnancy has been associated with deterioration of sRV function in short-term post-partum follow-up, but the long-term impact remains largely unknown.

Sex-related differences in spontaneous intracerebral hemorrhage outcomes: A prognostic study based on 111,112 medical records

ObjectiveTo identify sex-related differences in the outcome of hospitalized patients with spontaneous intracerebral hemorrhage (SICH), and to identify potential causal pathways between sex and SICH outcome.MethodsA total of 111,112 medical records of in-hospital patients with SICH were collected. Data- and expert-driven techniques were applied, such as a multivariate logistic regression model and causal mediation analysis. These analyses were used to determine the confounders and mediators, estimate the true effect of sex on the SICH outcome, and estimate the average causal mediation effect for each mediator.Results(1) Failure (disability or death) rates in women with SICH were significantly lower than in men with SICH. On the day of discharge, the odds ratio (OR) of failure between women and men was 0.9137 [95% confidence interval (CI), 0.8879–0.9402], while the odds ratio at 90 days post-discharge was 0.9353 (95% confidence interval, 0.9121–0.9591). (2) The sex-related difference in SICH outcome decreased with increasing age and disappeared after 75 years. (3) Deep coma, brainstem hemorrhage, and an infratentorial hemorrhage volume of >10 ml accounted for 62.76% (p < 0.001), 33.46% (p < 0.001), and 11.56% (p < 0.001) of the overall effect on the day of discharge, and for 52.28% (p < 0.001), 27.65% (p < 0.001), and 10.86% (p < 0.001) of the overall effect at the 90-day post-discharge.ConclusionMen have a higher failure risk than women, which may be partially mediated by a higher risk for deep coma, brainstem hemorrhage, and an infratentorial hemorrhage volume of >10 ml. Future work should explore the biological mechanisms underlying this difference.

INTERACTIONS BETWEEN BIOLOGICAL SEX AND THE X-LINKED VARIANT IRAK1 HAPLOTYPE IN MODULATING CLINICAL OUTCOME AND CELLULAR PHENOTYPES AFTER TRAUMA.

Sex-related outcome differences in trauma remain controversial. The mechanisms causing sex-biased outcomes are likely to have hormonal and genetic components, in which X-linked genetic polymorphisms may play distinct roles because of X-linked inheritance, hemizygosity in males, and X chromosome mosaicism in females. The study aimed to elucidate the contribution of biological sex and the common X-linked IRAK1 haplotype to posttrauma clinical complications, inflammatory cytokine and chemokine production, and polymorphonuclear cell and monocyte activation. Postinjury clinical outcome was tested in 1507 trauma patients (1,110 males, 397 females) after stratification by sex or the variant IRAK1 haplotype. Males showed a three- to fivefold greater frequency of posttrauma sepsis, but similar mortality compared to females. Stratification by the variant IRAK1 haplotype revealed increased pneumonia and urinary tract infection in Wild type (WT) versus variant IRAK1 males, whereas increased respiratory failures in variant versus WT females. Cytokine/chemokine profiles were tested in whole blood from a subset of patients (n = 81) and healthy controls (n = 51), which indicated sex-related differences in ex vivo lipopolysaccharide responsiveness manifesting in a 1.5- to 2-fold increased production rate of tumor necrosis factor α, interleukin-1β (IL-1β), IL-10, Macrophage Inflammatory Protein-1 Alpha, and MIP1β in WT male compared to WT female trauma patients. Variant IRAK1 decreased IL-6, IL-8, and interferon gamma-induced protein 10 production in male trauma subjects compared to WT, whereas cytokine/chemokine responses were similar in variant IRAK1 and WT female trauma subjects. Trauma-induced and lipopolysaccharide-stimulated polymorphonuclear cell and monocyte activation determined by using a set of cluster of differentiation markers and flow cytometry were not influenced by sex or variant IRAK1. These findings suggest that variant IRAK1 is a potential contributor to sex-based outcome differences, but its immunomodulatory impacts are modulated by biological sex.

Sex differences on outcomes following left atrial appendage occlusion in atrial fibrillation: A systematic review and meta-analysis.

There is a lack of sufficient data on sex-related differences in outcomes of nonvalvular atrial fibrillation (AF) patients following left atrial appendage occlusion (LAAO). We conducted a meta-analysis to investigate the procedural complications and long-term outcomes after LAAO in women versus men. We screened Medline, EMBASE, Cochrane Center Register of Controlled Trials, and Clinical Trials.gov. The inclusion criteria were studies targeting the sex-related differences in outcomes in nonvalvular AF patients treated by LAAO. Procedural endpoints of interest included success rate, pericardial complications, major bleeding, and vascular complications during hospitalization. Long-term outcomes included all-cause mortality and ischemic stroke during follow-up. Studies that merely considered sex in the subgroup analysis were not included. Six observational studies with a total of 64,035 patients were identified. The procedural success rates did not differ between sexes (odds ratio [OR]: 0.98, 95% confidence interval [CI]: 0.89-1.09, p = 0.77), while women experienced more pericardial complications (OR: 1.78, 95% CI: 1.58-2.01, p < 0.00001), major bleedings (OR: 2.04, 95% CI: 1.75-2.39, p < 0.00001), and vascular complications (OR: 1.75, 95% CI: 1.41-2.17, p < 0.00001) than men. The sensitivity analysis performed by removing the largest study showed good stability. The long-term mortality and stroke rates did not differ between women and men in either the 1-year subgroup or the 2-year subgroup. In conclusion, despite comparable procedural success rates, women have a significantly higher incidence of pericardial complications, major bleeding, and vascular complications following LAAO. The long-term mortality and stroke rates do not differ between the sexes.

Sex-Related Differences in Outcomes for Oropharyngeal Squamous Cell Carcinoma by HPV Status.

Background Overall survival for HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) has differed by sex, but little is known regarding cancer-specific outcomes. We assessed the independent association of sex with cancer-specific survival in patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). Methods We identified 14,183 patients from the Surveillance, Epidemiology, and End Results (SEER) program with OPSCC and tumor HPV status. We used Kaplan–Meier methods to compare overall survival (OS) and OPSCC-specific survival (HNCSS) by patient sex and by tumor HPV status. We then separately fit multivariable survival and competing risk models evaluating the association of sex on these outcomes by tumor HPV status and stratified by the use of guideline-concordant OPSCC treatment. Results A total of 10,210 persons with HPV-positive tumors (72.0%) and 3,973 with HPV-negative tumors (28.0%) were identified. A larger proportion of women had HPV-negative tumors (24.0%) versus HPV-positive tumors (13.2%; p < 0.001). Women with HPV-positive tumors were less likely to receive guideline-concordant treatment compared to men. In unadjusted survival analyses, women did not differ in OS or HNCSS compared to men for HPV-positive tumors but had worse OS and HNCSS for HPV-negative tumors. After adjustment, men and women with HPV-positive OPSCC did not differ in OS or HNCSS. However, women with HPV-negative tumors faced worse overall survival (hazard ratio (HR) 1.15, 95% CI 1.02–1.29) that persisted even after stratifying for stage-appropriate treatment (HR 1.28, 95% CI 1.11–1.47). Conclusions Women with HPV-positive OPSCC had similar survival outcomes compared to men, but those with HPV-negative tumors have worse overall and cancer-specific survival.

Sex-Related Differences in Outcomes After Endovascular Treatment of Patients With Late-Window Stroke.

Sex-related differences exist in many aspects of acute stroke and were mainly investigated in the early time window with conflicting results. However, data regarding sex disparities in late presenters are scarce. Therefore, we sought to investigate differences in outcomes between women and men treated with endovascular treatment in the late time window. Analyses were based on the SOLSTICE Consortium (Selection of Late-Window Stroke for Thrombectomy by Imaging Collateral Extent), which was an individual-patient level analysis of seven trials and registries. Baseline characteristics, 90-day functional independence (modified Rankin Scale score ≤2), mortality, and symptomatic intracranial hemorrhage were compared between women and men. Effect of sex on the association of age and successful reperfusion (final Thrombolysis in Cerebral Infarction 2b-3) with outcomes was assessed using multivariable logistic regression adjusted for age, National Institutes of Health Stroke Scale score, Alberta Stroke Program Early CT Score, time from onset to puncture, occlusion location, intravenous thrombolysis, and successful reperfusion, with interaction terms. Among 608 patients treated with endovascular treatment, 50.5% were women. Women were older than men (median age of 72 versus 68 years, P=0.02) and had a lower prevalence of tandem occlusions (14.0% versus 22.9%, P=0.005). Workflow times were similar between sexes. Adjusted outcomes did not differ between women and men. Functional independence at 90 days was achieved by 127 out of 292 women (43.5%) and 135 out of 291 men (46.4%). Mortality at 90 days (54 [18.5%] versus 48 [16.5%]) and symptomatic intracranial hemorrhage (37 [13.3%] versus 33 [11.6%]) were similar between women and men. There was no sex-by-age interaction on functional outcomes. However, men had higher likelihood of mortality (Pinteraction=0.003) and symptomatic intracranial hemorrhage (Pinteraction=0.017) with advancing age. Sex did not influence the relation between successful reperfusion and outcomes. In this multicenter analysis of late patients treated with endovascular treatment, sex was not associated with functional outcome. However, sex influenced the association between age and safety outcomes, with men experiencing worse outcomes with advancing age.

Sex-related differences in outcome after endovascular revascularization for lower extremity artery disease.

Background: Sex-related differences may influence the outcome of endovascular revascularization (EVR) in patients with lower extremity arterial disease (LEAD) even under optimized healthcare supply. Patients and methods: LEAD patients who underwent EVR at the Department of Cardiology I - Coronary and Peripheral Vascular Disease, Heart Failure, University Hospital Muenster, Germany between 2014 and 2016 were included into the retrospective study. Detailed information on risk factors and co-morbidities, medication, LEAD related measures, and interventional parameters were assessed. Outcome defined as technical success rate, complications, and mortality was analyzed up to 12 months follow-up. Results: In total, 165 female and 437 male LEAD patients were included. Women and men presented with comparable severity of LEAD in terms of critical limb threatening ischemia (46.2%), wound status (34.9%), and amputation rate (9.6%, all n.s.) at index. Intake of platelet inhibitors (65.8% female vs. 70.0% male), oral anticoagulants (21.3% vs. 25.4%), and statins (65.6% vs. 76.0%) was observed less frequently in female patients. Against the background of high technical success (85%), in-hospital death (0.8%), severe adverse cardiac (MCE; 1.7%), and limb events (MALE; 6.1%) occurred at low rates in either sex. Adjusted long-term mortality was not affected by patients' sex (female HR 0.755; p=0.312). Conclusions: Despite critical LEAD stages in every second patient, EVR was performed safe with high technical success rates in female and male patients. Long-term outcomes were observed at comparatively low rates in both sexes at the specialized vascular center. During aftercare, supply with statin therapy turned out improvable particularly in female LEAD patients.

Sex-related differences in stemless total shoulder arthroplasty.

BackgroundThe use of stemless humeral implants for shoulder arthroplasty is becoming increasingly widespread. However, little is known about the difference in clinical, functional, and radiographic outcomes of stemless shoulder arthroplasty between men and women. Men and women do have reported differences in size, strength, and bone quality. As such, the purpose of this study was to evaluate sex-related differences in outcomes when using stemless humeral implants.MethodsA retrospective review of 227 patients (men = 143 and women = 84) undergoing stemless shoulder arthroplasty was compared for sex-related differences. Clinical, functional, and radiographic outcomes were compared, including American Shoulder and Elbow Surgeons (ASES) scores, visual analog scale pain scores, range of motion, radiolucencies, operative data, implant data, and complications. Statistical analysis included descriptive statistics, t-tests, chi-square tests, and logistic regression.ResultsPreoperatively, men had a statistically significant greater range of motion of forward elevation (P < .01), external rotation (ER) at adduction (P = .04), ER at 90° abduction (P = .03), and baseline ASES scores (P < .01). At 2 years, there were no differences between men and women in ASES score (P = .12), visual analog scale pain score (P = .74), active ER (P = .98), implant migration, or radiolucencies (P > .99). Mean operating time was 9 minutes longer in male patients (P < .01). There was no significant difference in surgical complications, including dislocation, fracture, infection, or loosening. The three-year revision-free survival was 98.8% for women and 97.9% for men.ConclusionPatient sex is not predictive of postoperative functional outcomes after stemless shoulder arthroplasty. The operative time was significantly shorter in female patients, and there was no significant difference in surgical complications between men and women.

The influence of sex on ischemic stroke incidence, therapeutic procedures and in-hospital mortality: Results of the Spanish National Hospital Discharge.

Previous research has revealed sex-related differences in outcomes for people admitted to hospitals for ischemic stroke. We aimed to analyse the incidence, use of invasive procedures and in-hospital outcomes of ischemic stroke in Spain (2016-2018) using the Spanish National Hospital Discharge Database. We sought sex-related differences in incidence and in-hospital outcomes over time. We estimated the incidence of ischemic stroke in men and women. We analysed comorbidities (Charlson's comorbidity index, cardiovascular risk factors, alcohol abuse and atrial fibrillation), procedures (mechanical ventilation, endovascular thrombectomy and thrombolytic therapy) and outcomes. We matched each woman with a man with identical age, type of ischemic stroke and year of hospitalisation. We built Poisson regression models to obtain adjusted incidence rate ratios (IRRs). We tested in-hospital mortality (IHM) with logistic regression analyses. Ischemic stroke was coded in 172255 patients aged ≥35years (92524 men 53.7%). Men showed higher incidence rates (216.9 vs. 172.3/105 ; P<.001; IRR=1.57 (95% CI:1.55-1.59) than women. After matching, the use of endovascular thrombectomy (5.1% vs. 4.0%; P<.001) and thrombolytic therapy (7.6% vs. 6.8%; P<.001) was higher among women. IHM was significantly higher in women than in matched men (11.2% vs. 10.4%; P<.001). Women had a lower IHM than matched men when endovascular thrombectomy (9.4% vs. 12.1%; P=.001) or thrombolytic therapy (6.7% vs. 8.3%; P=.003) was coded. Patients of both sexes admitted for ischemic stroke who received thrombolytic therapy had lower IHM (OR=0.76; 95% CI:0.68-0.85 among men; and OR=0.58; 95% CI:0.52-0.64 among women), but endovascular thrombectomy was associated with a lower IHM only among women (OR=0.58; 95% CI:0.51-0.66). After multivariable adjusting, women admitted to the hospital for ischemic stroke had a significantly higher IHM than men (OR=1.16; 95% CI:1.12-1.21). Men had higher incidence rates of ischemic stroke than women. Women more often underwent thrombolytic therapy and endovascular thrombectomy but had a higher IHM.

Sex differences in vascular risk factors, in-hospital management, and outcomes of patients with acute ischemic stroke in China.

Previous assessments of sex differences for patients with acute ischemic stroke were limited in a specific region or population, narrow scope, or small sample size. Patients with acute ischemic stroke hospitalized in the China Stroke Center Alliance hospitals were analyzed. Absolute standardized differences (ASDs) were used to assess sex differences in vascular risk factors, guideline-recommended in-hospital management measures and outcomes, including stroke severity (National Institutes of Health Stroke Scale≥16), death/discharge against medical advice, major adverse cardiovascular events, pneumonia, and disability (modified Rankin Scale≥3). Of 838,229 patients analyzed, 524351 (62.6%) were men and 313,878 (37.4%) were women. Compared with men, women were older (68.6 vs. 64.7years), had higher prevalence of hypertension (67.7% vs. 62.4%), diabetes (24.7% vs. 19.5%), and atrial fibrillation (7.1% vs. 4.3%), but lower prevalence of smoking (4.5% vs. 56.6%) and drinking (2.6% vs 35.8%) (ASDs >10%). No sex differences were seen in guideline-directed management measures, indicated by risk-adjusted individual measures and the all-or-null summary measure (34.5% vs 34.9%, ASD=1.0%). Compared to men, women tended to have strokes that were more severe at presentation (6.5% vs. 4.5%, ASD=8.8%) and more disabilities at discharge (34.9% vs 30.5%, ASD =9.4%). However, all sex-related differences in outcomes were attenuated to null after risk adjustments (ASDs<2%). Compared to male patients, female patients had more vascular risk factors and received similar in-hospital care. They had strokes that were more severe at presentation and more disabilities at discharge, both of which may be explained by worse vascular risk profiles.

Sex-Related Clinical Characteristics and Outcomes of Patients Undergoing Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation.

The authors sought to assess sex-based differences in characteristics and outcomes of patients undergoing transcatheter edge-to-edge mitral valve repair (TMVR) for secondary mitral regurgitation (SMR). Subgroup analysis from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for HeartFailure Patients with Functional Mitral Regurgitation) trial indicated potential sex-related differences in outcomes after TMVR. The impact of sex on results after TMVR in a real-world setting is unknown. The authors assessed clinical outcomes and echocardiographic parameters in women and men undergoing TMVR for SMR between 2008 and 2018 who were included in the large, international, multicenter real-world EuroSMR registry (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation). A total of 1,233 patients, including 445 women (36%) and 788 men (64%), were analyzed. Although women were significantly older and had fewer comorbidities than men, TMVR was equally effective in women and men (mitral regurgitation [MR] grade≤2+ at discharge: 93.2% vs. 94.6% for women vs. men; p=0.35). All-cause mortality at 1 year (17.9% vs. 18.9%, adjusted hazard ratio: 0.806; p=0.46) and at 2-year follow-up (26.5% vs. 26.4%, adjusted hazard ratio: 0.757; p=0.26) were similar in women versus men after multivariate regression analysis. Durability of MR reduction, improvement in symptoms, quality of life, and functional capacity did also not differ during follow-up. Results from the EuroSMR registry confirmed effective and similar MR reduction with TMVR in women and men. There were no sex-related differences in clinical outcomes up to 2 years of follow-up.
