Differences in incidence, nature of symptoms, and duration of long COVID among hospitalised migrant and non-migrant patients in the Netherland: a retrospective cohort study

Abstract Background and aim Comprehensive data on long-COVID across ethnic and migrant groups are lacking. We investigated incidence, nature of symptoms, clinical predictors, and duration of long-COVID among COVID-19 hospitalised patients in the Netherlands by migration background. Methods We used COVID-19 admissions and follow up data (January 2021-July 2022) from Amsterdam University Medical Centers. We calculated long-COVID incidence proportions by migration background and assessed for clinical predictors via robust Poisson regressions. We then examined associations between migration background and long COVID using robust Poisson regressions and adjusted for derived clinical predictors, and other biologically relevant factors. Results 1886 patients were included. 483 patients had long-COVID (26%, 95% CI 24-28%) at 12 weeks post-discharge. Symptoms like dizziness, joint pain, and headache varied by migration background. Clinical predictors of long-COVID were female sex, hospital admission duration, intensive care unit admission, and receiving oxygen, or corticosteroid therapy. Long-COVID risk was higher among patients with migration background than Dutch origin patients after adjustments for derived clinical predictors, age, smoking, vaccination status, comorbidities and remdesivir treatment. Conclusions There are significant differences in occurrence, nature of symptoms, and duration of long-COVID by migration background. Studies assessing functional limitations and access to post-COVID healthcare are needed to help plan for appropriate and accessible healthcare interventions.

Burden of systemic inflammation and associated health outcomes in adults with atherosclerotic cardiovascular disease managed in routine care

Abstract Background The burden and outcomes of inflammation in people with atherosclerotic cardiovascular disease (ASCVD) are poorly defined, particularly beyond the controlled settings of trials and research cohorts. Methods We conducted a longitudinal observational study of adults with ASCVD undergoing C-reactive-protein (CRP) testing in routine healthcare in Stockholm, Sweden. After excluding CRP tests associated with acute illness and patients with medications/conditions that bias CRP interpretation, the systemic inflammation of participants was defined over a 3-month ascertainment window. Baseline determinants of CRP≥2 mg/L were explored with logistic regression, and baseline CRP categories were compared via Poisson and Cox regression for subsequent healthcare resource utilization and occurrence of major adverse cardiovascular events (MACE), heart failure hospitalization, and all-cause death. Result After applying inclusion/exclusion criteria, we identified 84,399 adults with ASCVD with a mean age of 71 years and of which 54% were men. In total, 60% had CRP≥2 mg/L. At baseline, female sex, older age, lower kidney function, albuminuria, diabetes, hypertension, and recent anemia, were associated with CRP≥2 mg/L. Conversely, the use of RASi, antiplatelets, and lipid-lowering therapy were associated with lower odds. Over a median follow-up of 6.4 years and compared to people with CRP <2 mg/L, those with CRP≥2 mg/L had a higher rate of hospitalizations, days spent in hospital, outpatient consultations, and dispensed medications during follow-up (P<0.05 for all). They also had a higher rate of MACE [adjusted hazard ratio (HR), 1.30; 95% CI, 1.27–1.33], heart failure hospitalization [1.24; 1.20–1.39], and all-cause death [1.35; 1.20–1.30]. Results were consistent across subgroups and more granular CRP categories, and robust to the exclusion of extreme CRP values or early events. Conclusions Two in three adults with ASCVD have systemic inflammation. A CRP≥2 mg/L is associated with excess healthcare resource utilization as well as increased rates of MACE, heart failure, and death.

Equitable Access, Lasting Results: The Influence of Socioeconomic Environment on Bariatric Surgery Outcomes.

Low socioeconomic status (SES) correlates with higher obesity rates and challenges in accessing treatments like bariatric surgery (BS). This study aims to assess SES's influence on medium-term BS outcomes in a setting of universal healthcare, ensuring equitable treatment access. We conducted a retrospective analysis of 193 BS patients (1997-2018) at a tertiary care hospital. Weight loss was expressed as change in % total weight loss (%TWL) and excess body weight (EBW) loss. Successful BS was defined as > 50% EBW loss. SES was gauged using quartiles of the Spanish Deprivation Index. A multivariable Cox regression model evaluated SES impact on BS success over follow-up. The mean follow-up was 6.9 ± 4.6years; patients averaged 43.9 ± 11.8years, with 29.7% men. Preoperative BMI was 48.2 ± 8.2kg/m2. At follow-up, BMI was 33.9 ± 6.6kg/m2, with 29.3 ± 12.02% of %TWL. No SES quartile differences in BS success were noted at follow-up (log rank p = 0.960). Cox regression revealed no SES disparities in BS outcomes post-adjustment. However, female sex (HR 1.903; p = 0.009) and diabetes mellitus (HR = 0.504; p = 0.010) correlated with weight-related outcomes. In a universal healthcare system with equitable treatment access, medium-term BS outcomes remain consistent irrespective of patients' socioeconomic status.

Determinants of appetite in the first year of life: Results from a prospective study of infants

Abstract Childhood obesity, a growing public health problem, was shown to be associated with appetite traits (ATs) in infancy but little research exists on the determinants of early appetite. We aimed to examine the association between parental, pregnancy and infant variables on ATs during the first year of life. We followed up 450 healthy term infants assessing Enjoyment of Food (EF), Food Responsiveness (FR), Satiety Responsiveness (SR) and Slowness in Eating (SE), using the Baby (at 2-4 weeks (wk) & 6m) and the Child (at 12m) Eating Behaviour Questionnaires. Associations between parental sociodemographic and lifestyle, pregnancy, infant feeding and anthropometric factors, and these ATs were investigated. Multivariable linear regression models were built for each AT, incorporating statistically significant variables from minimally adjusted models (sex, gestational age, and ethnicity). Results primarily focus on ATs at 2-4wks, as later ATs were largely influenced by these values. Higher father’s BMI (β = 0.013, p = 0.022) was associated with increased EF at 2-4wks. Later gestational age (β = 0.106, p = 0.032), and gestational diabetes (β = 0.538, p = 0.002) were associated with higher FR 2-4wk while mixed feeding compared to exclusively breast feeding (β =-0.281, p = 0.013) with lower FR 2-4wk. Female sex (β = 0.174, p = 0.009) was positively, while gestational age (β=-0.076, 0.022), father’s educational attainment (β=-0.199, p = 0.003), father habitual smoking (β=-0.167, p = 0.020) and 4wk WFA z-score (β = 0.087, p = 0.037) were negatively associated with SR 2-4wk. Lastly, higher 4wk WFA z-score (β=-0.151, p = 0.012) and bottle feeding (β=-0.378, p = 0.003) were associated with decreased SE 2-4wk. Acknowledging that a causal association cannot be established in an observational study, this data suggests that parental lifestyle and pregnancy factors could influence infant ATs and hence risk of later obesity, highlighting the importance of preconception health in mitigating the problem of childhood obesity. Key messages • Appetite traits in early infancy are influenced by infant feeding and anthropometric variables, but also by parental and pregnancy characteristics. • The importance of preconception health is paramount in mitigating the problem of childhood obesity.

Impact of atrial fibrillation on cardiac autonomic function in elderly patients

Abstract Introduction Cardiac autonomic dysfunction has been linked to an increased risk of mortality (1), stroke and silent brain lesions (2) and cognitive impairment (3) in patients with atrial fibrillation (AF). However, the impact of AF on cardiac autonomic function is poorly understood. Purpose We aimed to explore the impact of AF on cardiac autonomic function by comparing AF patients with a matched control cohort without AF. Methods We enrolled patients with and without AF from two ongoing, prospective, multicenter cohort studies (Swiss-AF Cohort and Swiss-AF Control) if they had a high-resolution 16-lead resting ECG recording in sinus rhythm for a duration of 5 minutes at baseline visit. Cardiac autonomic function was quantified by periodic repolarization dynamics (PRD), a marker of repolarization instability associated with sympathetic activity. PRD was quantified by means of wavelet analysis, as validated previously (4). Cardiac autonomic dysfunction was defined present if PRD exceeded the established cut-off of 10.0 deg2 (5). We built multivariable adjusted linear and logistic regression models to explore the association of AF with PRD and cardiac autonomic dysfunction. Results We included 2077 patients, 1113 (54%) from the AF cohort and 964 (46%) from the matched non-AF cohort. Baseline characteristics were well balanced between the groups (mean age 71 vs. 73 years in patients with and without AF, mean CHA2DS2-VASc score 3.0 vs. 3.5, female sex 31.3% vs. 36.6%). The median PRD was 18.2 deg2 (IQR 9.9-25.4) in patients with AF and 15.8 deg2 (IQR 8.1 -23.0) in patients without AF (p<0.001, Figure). 832 (75%) of the AF patients suffered from cardiac autonomic dysfunction, vs. 656 (68%) of the non-AF patients (p<0.001). Multivariable adjusted linear regression analysis revealed an independent association of AF with continuous levels of PRD (beta-coefficient -1.57, 95% CI -2.64 - -0.488, p=0.004). Further, AF was independently associated with the presence of cardiac autonomic dysfunction (Odds Ratio 1.48, 95% CI 1.18-1.87, p<0.001, Table). Conclusion In this cross-sectional analysis of a patient population with and without AF, AF was independently associated with increased PRD values, reflecting sympathetic predominance, and with the presence of cardiac autonomic dysfunction. These findings implicate a relevant role of AF in the development of cardiac autonomic dysfunction in elderly patients.Figure

Musculoskeletal disorders and risk factors in the modern era: results from the Specchio cohort

Abstract Background Musculoskeletal disorders (MSDs) represent a major challenge for occupational and public health, but data are scarce in Switzerland or concentrated on a few sectors of activities. The aim of this study is to provide results on the prevalence and risk and protective factors of MSDs in the general working-age population of the Geneva canton, Switzerland. Methods A cross-sectional analysis was conducted as part of Specchio population-based cohort study. Prevalence and associations between MSDs and sociodemographic variables, individual behaviour (smoking, physical activity, sleep), health conditions (BMI, chronic diseases), physical and psychological risks at work were examined using regression models. The impact of teleworking was also evaluated. Results 2’733 participants took part in the survey, of which 38% were men, and mean age was 50. Overall prevalence of MSDs was 74% among men and 84% among women. 80% of the individuals experience back pain and 56% shoulder pain. Among individuals who experienced MSDs, 55.2% consulted a healthcare professional. The risk factors for MSDs were female sex (OR = 1.95; 95% IC = 1.55-2.28), body mass index (obese) (2.2; 1.51-3.32), lower education (1.77; 0.84-4.37), smoking (1.65; 1.19-2.35), exposure to physical risks (3.54; 2.78-4.51), stress at work (effort-reward imbalance) (3.23; 2.45-4.29) and a poor work-life balance (2.36; 1.88-2.97). The prevalence of MSDs remained high among workers who telework (78% versus 84% in working population). Conclusions This study, carried out in a large population-based cohort, confirmed several risk factors for MSDs. These results will contribute to the implementation of prevention strategies, especially as teleworking has gained in importance in recent years, which may have aggravated workers’ isolation and stress, sedentariness, and poor body posture. Main message: These data confirm the weight of musculoskeletal disorders and will help implementation of prevention health strategies. Key messages • The relationship between psychosocial risks at work and the occurrence of Musculoskeletal Disorders (MSDs) persists even following adjustment for exposure to physical risks and individual risk factors. • The prevalence of musculoskeletal (MSDs) disorders remained high among workers who telework.

A 3-year retrospective exploration of predictors for cardiac arrest in atrial fibrillation

Abstract Background An increasing correlation between atrial fibrillation (AF) and a heightened risk of cardiac arrest is emerging. Yet, the specific predictors of cardiac arrest in hospitalized patients with AF remain unclear. Purpose This study aims to identify these predictors, providing essential insights for refined risk assessment and targeted clinical interventions. Methods Adult patients hospitalized between 2018 and 2020 with a primary diagnosis of AF with or without cardiac arrest were identified using the International Classification of Diseases, Tenth Revision (ICD-10) code. Demographics and comorbidities were recorded. Logistic regression was employed to identify predictors of increased cardiac arrest. Results In a study of 272,028 hospitalizations with AF, 2,352 patients suffered cardiac arrest, and 523 died during hospitalization. Factors associated with increased odds of cardiac arrest include heart failure (OR = 1.79, 95% CI: 1.60–2.00), cardiogenic shock (OR = 2.95, 95% CI: 2.35–3.71), history of coronary angioplasty or bypass (OR = 1.79, 95% CI: 1.59–2.02), chronic kidney disease (OR = 1.26, 95% CI: 1.12–1.42), end-stage kidney disease (OR = 2.34, 95% CI: 1.98–2.77), and septic shock (OR = 6.50, 95% CI: 4.80–8.80). Chronic obstructive pulmonary disease (COPD) and infection were associated with a 13% (OR = 1.13, 95% CI: 1.02–1.26) and 45% (OR = 1.45, 95% CI: 1.25–1.68) increase in odds for cardiac arrest, respectively. Increased age (OR = 0.99, 95% CI: 0.98–0.99) and female sex (OR = 0.83, 95% CI: 0.76–0.91) showed an inverse relation with cardiac arrest. Hypertension and obesity exhibited protective effects against cardiac arrest, with odds ratios of 0.85 (95% CI: 0.74–0.97) and 0.83 (95% CI: 0.75–0.93), respectively. Conclusion Our study underscores the intricate web of factors influencing cardiac arrest risk in AF patients. A personalized approach to risk assessment in the context of AF might be needed.

Primary inflammatory disease in heart failure with preserved ejection fraction

Abstract Background Inflammation plays a fundamental role in the pathogenesis of heart failure (HF) with preserved ejection fraction (HFpEF). In most patients, inflammation develops secondary to cardiometabolic comorbidities, but in some, HFpEF develops in the setting of underlying systemic inflammatory diseases represented by rheumatoid arthritis. Purpose This study aimed to investigate the prevalence, pathophysiology, and outcome of patients with HFpEF and primary inflammatory diseases. Methods Consecutive patients undergoing hemodynamic exercise testing with concurrent expiratory gas analysis to evaluate dyspnea of unknown cause were identified. HFpEF was defined as left ventricular ejection fraction ≥50% and pulmonary capillary wedge pressure ≥15 mmHg (rest) or ≥25 mmHg (exercise). Patients with HFpEF were divided into groups with and without primary inflammatory diseases. Patients without inflammatory disease were divided into tertiles according to the value of C-reactive protein (CRP). Results Of 982 consecutively evaluated patients with HFpEF diagnosed (577 female, mean age 68 years), 79 (8%) had primary inflammatory disease. In multivariable logistic regression, female sex (OR 1.88; 95% CI 1.01-3.52), higher resting heart rate (OR 1.18; 95% CI 1.08-1.30), lower hemoglobin level (OR 0.84; 95% CI 0.70-0.99), absence of history of atrial fibrillation (OR 0.45; 95% CI 0.24-0.86) and absence of epicardial coronary artery disease (OR 0.45; 95% CI 0.22-0.93) were independently associated with inflammatory disease. Hemodynamics at rest and exercise did not differ between the groups, but peripheral oxygen extraction was lower in those with inflammatory disease, reflected by lower arterial-venous oxygen content difference (Ca-vO2) at rest (4.2±0.7 mL/dL vs 4.6±1.0 mL/dL, P<.001) and during exercise (9.3±2.2 mL/dL vs 10.4±2.2 mL/dL, P<.001) (Figure 1A), suggesting a greater peripheral deficit, and ventilatory efficiency (VE/VCO2 slope) was also more impaired (38.0±7.9 vs 36.2±7.3, P=.035). The HFpEF patients without inflammatory disease falling in the highest tertile of CRP) displayed lower Ca-vO2 during exercise, more closely resembling peripheral deficits observed in those with inflammatory disease (Figure 1B). During a median follow-up of 3.0 years, the composite outcome of all-cause deaths and HF hospitalization occurred in 127 patients (14%). Patients with HFpEF and inflammatory disease showed a higher incidence of composite outcome than those without (log-rank P=.030; Figure 2). Patients with inflammatory disease had higher risk of composite outcome compared to those without in adjusted analyses (HR 1.93; 95% CI 1.15-3.23), which was primarily attributable to higher risk of HF hospitalization (HR 2.85; 95% CI 1.08-7.52). Conclusion Patients with HFpEF and primary inflammatory disease have similar hemodynamic derangements but greater peripheral deficits in oxygen transport and higher risk for adverse outcome compared to those without.

Sex differences in aortic prognosis in Marfan patients, a retrospective longitudinal study from the REPAG registry

Abstract Introduction Previous studies(1-4) have suggested a more favourable aortic outcome among women with Marfan syndrome (MFS), although the precise underlying mechanism remains not completely understood. In this retrospective longitudinal study, we aim to evaluate sex differences in aortic events in a large cohort of Marfan patients seen in 11 tertiary centres in Spain. Methods Patients with diagnosis of Marfan syndrome (MFS) were included. Data on aortic events (AE) including elective aortic surgeries, acute aortic syndrome or death were incorporated. Survival free of the combined endpoint of death or first aortic event (elective aortic surgery or acute aortic syndrome) was compared between male and female by the Kaplan-Meier curves, log-rank test and subsequent Cox regression analysis. Results A total of 442 patients with MFS where included, 48.2% female and 56.2% index cases. Although systemic score and proband proportion was not different between both sexes, the diagnosis was earlier in males (p=0.01) (Table). Furthermore, among adult patients, males exhibited greater height, weight, and body surface area (BSA). Absolute aortic root diameter at baseline was greater in males, but not BSA-indexed diameters or z-scores. Combined endpoint of death or aortic event was observed in 192 patients (120 male, 72 female, p=<0.00001). Female sex had better survival free of the combined endpoint in a multivariable Cox analysis (HR 0.41 95% CI=0.30–0.55) with a mean survival free of the combined endpoint of 41.3yrs in male and 61.4 years in females (p<0.0001) (Figure).Although a higher proportion of elective aortic interventions as first event was observed in males (66.7% vs 52.8%), the proportion of type A dissections was similar between both sexes (26.7 vs 26.4%) with increased frequency of type B dissections in females as first aortic event (4.2 vs 15.3%) (p=0.026) Conclusions Male patients with MFS present higher aortic root diameters but similar BSA-indexed and zscores than females. Survival free of first aortic event or death is reduced in male with MFS, with greater frequency of elective aortic intervention. Although this last is driven by absolute aortic diameter, no increase on type A dissection was observed in women. These findings might suggest a potentially less aggressive manifestation of proximal aortic disease in women with MFS.Table:Comparison male and female Marfan

Implications of age and sex on the diagnostic yield of sudden arrhythmic death syndrome

Abstract Introduction Sudden arrhythmic death syndrome (SADS) refers to an unexplained sudden death with a negative autopsy. An inherited cardiac condition (ICC) may be diagnosed through familial clinical evaluation (FE) or post-mortem genetic testing (molecular autopsy [MA]) or both. We aimed to investigate the impact of age and sex of SADS decedents on the diagnostic yield and aetiology to facilitate a targeted approach to management. Methods Consecutive referrals to a single centre for FE only, MA only or both, following a SADS death were included. First-degree family members underwent comprehensive FE. A panel of 36 cardiac genes was sequenced for MA. A post-mortem diagnosis could be obtained by either FE, MA or both. A Bayesian framework for analysis was performed to identify associations. Results Seven-hundred-and-sixty SADS decedents (66% male; mean age 31±12 years) were investigated. The overall diagnostic yield for an ICC was 37% (32-42%) and 9% (6-12%) for FE and MA cohorts, respectively. In a subset where both MA and FE were performed the diagnostic yield was 45% (38-61%). For each year increase in age, the relative risk of an FE diagnosis of long QT syndrome (LQTS) or Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) versus remaining unexplained declined by 5.6% (RR 0.94 [0.91-0.98]) and by 11% (RR 0.89 [0.81-0.97]), respectively. Females were more likely to have a diagnosis compared with males by both FE (40% [34-45%] vs 36% [31-41%]) and MA (15% [10-21%] vs 6% [3-8%]). Females (8.1% [4.1-13.4%)], were more likely to be diagnosed with LQTS than males (1.2% [0.2-2.7%]) in the MA cohort. Conclusions After a SADS death, the diagnostic yield of comprehensive FE, MA or both in an expert setting can be up to 45%. Younger age of death is associated with greater likelihood of LQTS and CPVT diagnosis with the highest yield in children and adolescents. Female sex in SADS decedents is associated with a higher yield of LQTS in MA. These data highlight the relative utility of FE and MA depending on age and sex for determining underlying diagnoses following SADS deaths.

Masked hypertension is highly prevalent among patients with high-normal office blood pressure - based on the results of the Hungarian ABPM Registry

Abstract Background Current European guidelines recommend initiating antihypertensive treatment for patients with high-normal office blood pressure (HNOBP) if their cardiovascular (CV) risk is very high.1 Ambulatory blood pressure monitoring (ABPM) is a recommended tool to identify whitecoat- (WCH) and masked hypertension (MH), and both conditions can be present in patients with HNOBP. Purpose The purpose of our study was to assess the prevalence of white-coat and masked hypertension in patients with HNOBP, the proportion of very high CV risk, and to identify the predictors of WCH and MH. Methods We collected data from the Hungarian ABPM Registry, which is an ongoing, multicenter, open-label, observational study including 38720 adult patients. ABPMs were performed with validated Meditech ABPM-06 monitors. We analyzed the ABPM curves of 4389 HNOBP patients. In the diagnosis of hypertension, 24 hour-, daytime- and nighttime mean BP values were each considered separately. OBP measurements and ABPMs were performed by GPs, internists and cardiologists. 89 patients were excluded due to missing data. Results ABPM recordings confirmed MH in 67.4%(n=2899) of the cases, while WCH in 15.3%(n=659). In 17.3%(n=742) BP was in HN category both in the office and with ABPM (apparent high-normal blood pressure /appHNBP/). WCH patients (57.11±17.47) were older, than appHNBP (54.54±16.9), and MH patients (53.38±16.70)(p<0.001). WCH (19.4%, n=489) and appHNBP (19.4%, n=488) were more frequent among females, than in males (14.3%, n=254; 9.6%, n=170, respectively, p<0.001). However, MH was more prevalent in males compared to females (76.2%(n=1355) vs 61.2%(n=1544), respectively, p<0.001). Snoring, obesity and diabetes mellitus were more frequent in MH than in appHNBP and WHC patients (Snoring: 30.6%(n=887) vs. 25.7%(n=191) vs. 20.8%(n=137), p<0.001; Obesity: 22.9%(n=663) vs. 16.0%(n=119) vs. 13.4%(n=88), p<0.001;Diabetes mellitus: 12.1%(n=350) vs. 8.9%(n=66) vs. 9.9%(n=65), respectively, p=0.025). Independent predictors of WCH were age (OR=1.01[1.003;1.02]), female sex (OR=1.50[1.19;1.89]) and snoring (OR=0.76[0.59;0.97]). Independent predictors of MH were male sex (OR=1.69[1.43;2.00]), snoring (OR=1.27[1.06;1.53]) and obesity (OR=1.55[1.25;1.92]). 76% of all patients received antihypertensive treatment irrespective of the BP groups (WCH: 76.2%(n=502), appHNBP: 76.3%(n=566), MH: 76.5%(n=2217), p=NS). 11.7%(n=502) of all patients had very high CV risk and only 2.5%(n=25) did not receive antihypertensive treatment. Similar results were found among WCH, appHNBP and MH patients (very high CV risk: 13.8%(n=91) vs. 11.2%(n=83) vs.11.7%(n=328), p=NS; no treatment: 1.9%(n=3) vs. 1.7%(n=3) vs. 2.8%(n=19), p=NS). Conclusions In patients with HNOBP, MH is highly prevalent. MH might be suspected in young, obese, male patients with diabetes mellitus and snoring. WCH was more frequent in older females. Based on our data, the majority of patients with HNOBP and very high CV risk are treated.

Measuring laypeople’s notions of intersex in the Netherlands and Flanders

Abstract Introduction In emancipation policy, the ‘I’ is often added to the LGBTI+-acronym. Yet it is still unknown to what extent this term is known and understood by the general population, and what attitudes toward intersex (people) are. In the current study, we describe the construction and development of the Intersex Knowledge and Attitudes Scale (IKAS), as well as the results from this baseline measurement in the Dutch and Flemish population. Methods The IKAS was developed after a carefully documented stepped process of literature scan, expert consultations, and pretesting. A representative sample of 2,003 respondents (1,000 Dutch and 1,003 Flemish) participated in the study. To determine the dimensionality of the scale, we performed EFA and CFA with measurement invariance constraints. We also performed a baseline measurement of knowledge and attitudes towards intersex people in the general population, and determined predictors of attitudes toward intersex people in regression analyses. Results Two-thirds of the sample had no (correct) knowledge of the term intersex. Even among the intersex respondents, only one person was aware of the term intersex. The average attitude was moderately positive to neutral. Having a female gender or birth sex, an advanced level of education, lower importance of religion, belonging to a minority group, more tolerant gender beliefs, and preexisting knowledge on the topic all resulted in more positive attitudes. Conclusions Both in Flanders and the Netherlands there still is room for improvement in terms of knowledge and attitudes towards intersex people. More knowledge may lead to more understanding, so that intersex people can be more open. Second, it is recommended to challenge beliefs of sex and gender as binary categories, because people who have less issues with people who do not entirely fall in these categories, also have more accepting attitudes toward intersex people. Key messages • It is vital to include intersex in monitoring studies of population attitudes, to be able to genuinely incorporate the ‘I’ in LGBTI+ in emancipation policies. • To increase acceptance of intersex people in society, knowledge about intersex in the general population should be expanded, and acceptance of people who do not fit into the binary should be promoted.

Intra, short and long-term results of mitral VIV for the degenerated surgical mitral prosthesis from italian VIV registry (MIVIV registry)

Abstract Background/Introduction Reoperation of failed bioprosthetic mitral valves is associated with significant morbidity and mortality. Transcatheter mitral valve-in-valve (MViV) replacement was explored early in the development of THVs with transseptal/transfemoral (TS/TF) and transapical (TA) approaches. Purpose This is the first Italian Registry on mitral VIV and it was designed to explore contemporary MViV outcomes with all types of balloon expandable valves. The present study out of the registry aims to asses the >10 years follow-up outcomes in terms of mortality, gender diversity, and perioperative result. Methods Participating centers used standardized definitions to collect clinical information, including patient demographic characteristics, comorbidities, functional status, quality of life indexes, procedural details, and patient outcomes from consecutive MViV cases. Cohort of 265 patients was available for the primary analysis and follow-up too.The patients were grouped by 11 hospitals in Italy performing VIV for degenerated biological mitral prostheses. Results A total of 265 pts underwent mitral VIV due to bioprosthesis degeneration between January 2010 and January 2023. They have been subdivided by transfemoral (TF) with 117 (44%) pts and transapical (TA) with 148 (55,8%) pts. Most of the patients were of female sex (59,2%) and EuroScore II for surgical re-operation was 16.1%. Mixed disease (48%) was more common than mitral regurgitation (29%) and stenosis (22%). 69,8% of the total cohort was in class NYHA III and the mean LVEF was 54%.Otherwise, there were no significant demographic differences between patients undergoing TS and TA. In TF there was more severe PVL (5%)(p-value: 0,001) and much more cases of severe grade of stenosis (54,7%) and regurgitation (57%)(p-value< 0,0001). Considering intraoperative outcomes, technical success has been established in around 97,7% of the total cohort without difference btw groups. Only 3,3% died during hospitalization without difference between groups (P-value=0,735). LVOT obstruction has been seen in 3,4% in the case of TA and 0 for TF. Only 1,5% of the total cohort underwent surgical conversion as well as embolization in only 1,1%. Overall survival from the total cohort was 91,3% at >10 years, Figure 1. Concerning the freedom from cardiac death (CV death) was 96,6% in the total cohort at 13 years. Concerning the difference between access, the general survival is established at 97,4% in TF while 86,3% in TA (p-value =0,050)(Figure 2). Freedom from CV death was 99,1% in TF and 94,5 in TA (p-value=0,209). In gender analysis differentiation, the general survival in females was 98,5% in TF and 85,6% in TA at 13 years (p-value=0,056). Conclusion(s) Transcatheter MViV using a balloon-expandable valve is associated with high technical success, a low complication rate, and a solid long-term benefit in terms of survival. Transseptal access was associated with lower mortality compared with TA access.Figure 1Figure 2

Insights into retroperitoneal hemorrhage management: result from a tertiary cardiovascular center prospective cohort

Abstract Background Although rare, retroperitoneal hemorrhage (RPH) during percutaneous cardiovascular interventions is still potentially fatal, poses a critical challenge, often necessitating swift and precise management strategies. Its management is still controversial, and available recommendations are mostly based on expert opinion, and not updated according to recent advancement in the field of interventional cardiology. Purpose To present the rate, clinical characteristics and modern management of patients complicating with RPH in a large tertiary cardiovascular center Method We collected prospectively all consecutive RPH events encountered in the catheterization laboratories of a large tertiary cardiovascular center during 2014-2022. Procedural data from all the diagnostic and therapeutic procedures performed in the same time period, were retrieved from electronic hospital records (EHR). Results Among 89,361 percutaneous cardiovascular diagnostic or therapeutic procedures performed on 69596 patients, 52 (0.058%) episodes (patients) of RPH, (mean age of 56.37±16.84 years with female sex predominance of 36 (69.23%)). Also 2 (3.8%) patients died due to RPH. Non-contrast abdominopelvic CT scan was the most common primary imaging modality for RPH diagnosis, followed by DSA angiography. Of note, 13 (25 %) of patients returned directly to catheterization laboratory for RPH evaluation. Thirty-one (59.6%) patients were ultimately treated conservatively and no patient treated surgically. Structural and peripheral procedures were more prone to RPH. Still a median time of 7.5 hours was needed for RPH diagnosis. Contralateral access was the dominant approach for treating RPH, and although balloon tamponade was used in 11 (52.4 %) patients, 17 (80.9 %) patients were treated ultimately with covered stents; deep femoral and internal iliac arteries were covered in 1 (5.9%) and 2 (11.8%) patients, respectively. Patients treated endovascularly for RPH had higher acute kidney injury and longer hospital stays. Further comprehensive analysis regarding the potential risk factors of RPH are pending. Conclusion Our preliminary analysis from a large tertiary cardiovascular center database, showed RPH is still rare, with acceptable mortality rate of 3.83%. Our data showed the necessity of more precise probability assessment tools to improve the diagnostic time.

SMART-2D: a novel scoring system to predict non diagnostic exercise stress echocardiography in renal transplant candidates

Abstract Background Exercise stress echocardiography (ESE) is often used for pre-renal transplant risk stratification. Nearly 20% of ESE may be non-diagnostic, resulting in delays to transplant and increased healthcare cost. A simple, reliable tool for predicting non-diagnostic ESE may streamline assessment. Methods Retrospective analysis of 898 kidney transplant candidates between 2013-2020 who underwent exercise stress echocardiography for pre-transplant cardiovascular assessment was performed. The cohort was separated into a derivation and validation set. Multivariable logistic regression identified predictors of non-diagnostic ESE. Covariates associated with non-diagnostic ESE (p<0.10) on univariate analysis were included in the multivariable model. From this model, only variables with p<0.05 were included for score development. Model discrimination was assessed by area under the receiver operating curve (AUROC). Results Non-diagnostic ESE occurred in 17% (151/898). Predictors of non-diagnostic study formed the scoring system: 1 point for female sex, 2 points for BMI >40, 1 point for age >55, Heart Rate<55 4 points, <65 3 points and <75 2 points. LV Hypertrophy was assigned 2 points, Type 1 Diabetes 3 points and Type 2 diabetes 1 point, LV Dysfunction was assigned 2 points. This scoring system had excellent discriminative ability (derivation AUROC 0.80, validation AUROC 0.81). A score of 8 or more had a specificity of 97% and a positive likelihood ratio of 9.4 for non-diagnostic ESE. A score of <8 had a negative predictive value of 86%. Patients with Non-Diagnostic ESE had longer time to transplantation (695 vs 636 days), and more investigations performed (43.05% vs 17.94%, p<0.001) and less likely to receive a renal transplant (OR 0.47, p<0.001). Conclusion Non diagnostic ESE in pre-transplant assessment causes significant delays to patient care. A simple clinical scoring system may identify patients likely to have non-diagnostic ESE and can be utilised to identify patients who may benefit from alternative risk-stratification investigations.

Ethnic minorities who complete cardiac rehabilitation achieve equivalent functional capacity outcomes after cardiac rehabilitation but only half complete

Abstract Background Cardiac rehabilitation (CR) reduces the risk of death and repeat cardiac events and improves multiple patient outcomes. Ethnic minority backgrounds experience significant health disparities, often due to lack of fluency in dominant language and higher rates of cardiovascular disease risk factors. Despite these issues, outcomes for ethnic minorities from CR are rarely differentiated and participation in CR programs infrequently reported. Purpose To compare participation in and exercise outcomes from CR programs for patients from ethnic minorities versus the majority. Methods A secondary analysis from a national CR audit including 2335 CR participants. Ethnic minority was defined as having poor English language fluency requiring an interpreter for CR assessment. Functional capacity was assessed using 6-minute walk test (6MWT) or metabolic equivalent of tasks (METs). Binary logistic regression model was created to identify independent predictors of completion, accounting for baseline variables. Multiple linear regression models were used to determine if ethnic minority status was an independent predictor of change in 6MWT and METs after adjusting for baseline characteristics. Results Of the 2335 participants, 326 (14%) were from ethnic minorities. The mean age was 66.3±12.4 years and 70% males. There were no differences between minority and majority groups in relation to baseline characteristics. The most common referral diagnosis was myocardial infarction (27%), angina (25%), other – arrhythmias, cardiac devices, valve diseases/procedures (24%), and cardiac surgery (24%). Ethnic minorities were half as likely to complete CR (OR 0.49, 95% CI 0.38, 0.65) adjusted for age, sex, diagnosis, minority status, smoking, referral site and wait time (Table 1). Other factors that increase completion likelihood included all other cardiac diagnoses (compared to myocardial infarction as reference) and non-smokers, whereas major referral centre and female sex negatively impacted completion. Patients from ethnic minority backgrounds had less functional capacity at CR entry compared to the majority (379.9±118 versus 430.7±103 metres, p<0.001), though METs were comparable (6.69±2.73 versus 6.46±2.28 mg/kg/min, p=0.69). However, improvements were equivalent for 6MWT: minority 71.03±58.57 versus majority 71.37±61.16 (p=0.96), and for METs: minority 3.01±1.66 versus majority 3.13±1.74 mg/kg/min (p=0.77). Ethnic minority status was not an independent predictor of change in 6MWT and METs after accounting for age, sex, diagnosis, smoking, referral site, and wait time. Conclusion For patients from ethnic minority groups who completed CR, exercise/functional capacity outcomes were equivalent to majority participants, however less than one-in-two completed. CR programs should consider the needs of ethnic minority groups, particularly in relation to language and tailor content and delivery to promote participation and ensure more equitable access.

Transcatheter versus surgical aortic valve replacement in patients younger than 65 years: analysis from the national inpatient sample database

Abstract Background Data on the relative utilization and outcomes of transcatheter aortic valve replacement (TAVR) versus surgical AVR (SAVR) in patients <65 years are limited. Purpose To compare the relative utilization and outcomes of TAVR versus SAVR in patients <65 years in the United States. Methods We queried the National Inpatient Sample (2016-2020) to identify patients <65 years hospitalized for isolated AVR. In-hospital outcomes of TAVR versus SAVR were compared using multivariable regression and propensity-matching analyses. Results Of 74,155 patients aged <65 years hospitalized for isolated AVR, 17,300 (23.3%) underwent isolated TAVR, and 56,855 (76.7%) underwent isolated SAVR. From 2016-2020, the use of TAVR increased, while the use of SAVR decreased in patients <65 years (both ptrend<0.01). Factors independently associated with TAVR selection in patients <65 years included female sex, congestive heart failure, pulmonary disease, renal failure, liver disease, cancer, and prior revascularization. Factors independently associated with SAVR selection included bicuspid aortic valve. After adjustment for baseline characteristics, TAVR was associated with lower odds of in-hospital mortality (adjusted odds ratio [aOR] 0.61, 95% confidence interval [CI] 0.38-0.97), stroke (aOR 0.58, 95% CI 0.38-0.90), acute kidney injury (aOR 0.41, 95% CI 0.34-0.49), and major bleeding (aOR 0.62, 95% CI 0.38-0.96), and higher vascular complications compared with SAVR (aOR 2.39, 95% CI 1.75-3.24). Length of stay was shorter and nonhome discharges were lower with TAVR (all p<0.01). Similar findings were observed in the propensity-matched cohort. Conclusions This nationwide observational analysis showed that TAVR is a feasible treatment option for patients <65 years with lower in-hospital mortality and resource utilization compared with SAVR.Central Illustration

Sex-specific guideline target value attainment and prognostic value of low-density lipoprotein cholesterol in tertiary care

Abstract Background Factors contributing to guideline-target-level-attainment of low-density lipoprotein cholesterol (LDL-C) in countries with high healthcare expenditure are incompletely understood. Purpose the primary aim of this study was to test two hypotheses: 1) LDL-C control may be inferior in women versus men; 2) within the secondary prevention group, presence of a previous acute atherothrombotic event (acute myocardial infarction and stroke) may result in superior LDL-C control. Methods LDL-C levels and guideline target level attainment were determined in 4090 consecutive patients referred for myocardial perfusion single photon emission tomography (MPI-SPECT) between 2010 and 2016. Findings were validated in an independent cohort (n=1228) of consecutively enrolled patients in an outpatient cardiac rehabilitation program, between 2016 and 2023. Results About one third of patients (33%) were women, median age was 68 years, 1439 patients had a history of atherothrombosis, 759 patients a history of atherosclerosis without atherothrombosis, and 1892 were in primary prevention. LDL-C levels were higher and guideline target level attainment worse in women than in men in all three strata: age-adjusted difference in atherothrombosis 0.19 mmol/L (95%CI 0.03,0.35 mmol), guideline-target-value-attainment 39.5 % versus 49.4%, p<0.01; in atherosclerosis 0.33 mmol/L (95%CI 0.10-0.57), guideline-target-value-attainment 27.3 % versus 42.2 %, p<0.01; and in primary prevention 0.24 mmol/L (95% CI 0.13-0.38). This was confirmed in the validation cohort. LDL-C levels were higher and guideline-target-value-attainment worse in women versus men: age-adjusted difference age-adjusted difference 0.17 mmol/L (95%CI 0.02-0.33) guideline-target-value-attainment 43.8% versus 49.5%, After multivariate adjustment, female sex remained an independent predictor for higher LDL-C levels. LDL-C concentrations with atherothrombosis was 1.93 mmol/L (IQR 1.48-2.47) versus 2.07 mmol/L (IQR 1.40-2.72, p=0.003) with atherosclerosis and guideline target value attainment 47.5% vs 38.6%, p<0.001, respectively. Conclusion Concerning age-adjusted sex-inequalities with higher LDL-C levels and lower guideline-target-value-attainment in women were found in both primary and secondary prevention. Within secondary prevention, a previous atherothrombotic event was associated with lower LDL-C levels and higher guideline-target-value-attainment.

Endarterectomy in CTEPH: hemodynamic improvement and RV-PA coupling

Abstract Introduction Pulmonary artery endarterectomy (PAE) remains the gold standard in treating chronic thromboembolic pulmonary hypertension (CTEPH). Reducing the thrombotic burden and mechanical obstruction of the pulmonary artery (PA) leads to significant hemodynamic improvement, allowing for favorable right ventricular (RV) remodeling. Methods Single center retrospective study, including 30 pts submitted to PEA over a 7-year period. Hemodynamic assessment was performed by right heart catheterization (RHC) before PEA, immediately after and at 6-month follow-up (FUP). Echocardiographic assessment of RV function was acquired at baseline and 6m FUP. Mean absolute differences were calculated before and after PEA. Differences between groups were assessed with ANOVA analysis and ROC curve analysis allowed us to define a cut-off point in mPAP reduction to predict favorable RV remodeling. Results We included 30 pts with a mean age of 57,9 ± 13 years old and slight predominance of female sex (57%). Regarding risk assessment with the 4 strata tool at baseline, 23% of pts were high risk, 20% intermediate high, 27% intermediate low and 6% at low risk. Pulmonary hemodynamics improved immediately after PEA, as indicated by a mean reduction of 28,3 ±17 mmHg in mPAP; 44,4±27,6mmHg in sPAP; 8±3,4 Wu in PVR and an increase in CO of 0,5±1 l/min. This improvement was sustained at 6-m post PEA assessment, with a mean reduction of 31,5 ±26,7 mmHg in mPAP; 48,3±41,2mmHg in sPAP; 6,3±6,2Wu in PVR and a 0,5±1 l/min increase in CO. Regarding RV remodeling at 6m post PEA, an increase of 0.15±0.2mm/mmHg in TAPSE/PSAP ratio and 3±2,8cm/s in Tricuspid S’ were recorded. RV/PA uncoupling, defined as TAPSE/PSAP <0,31 mm/mmHg, was evident in 73% of pts at baseline, 25% of which recovered at 6m follow-up. There were no significant differences between groups, according to the 4 strata risk assessment at baseline, regarding pulmonary hemodynamics and RV remodeling. Through ROC curve analysis, we were able to define a cut-off point of 37mmHg in immediate mPAP post-op reduction to predict RV-RA coupling normalization at 6-m FUP (sensitivity 70%, specificity 89%). Conclusions PEA remains a cornerstone of CTEPH treatment. It’s impact on improving pulmonary hemodynamics is immediate and maintained at 6-month FUP. This improvement may be expected regardless of risk assessment at baseline. Reducing RV afterload allows favorable remodeling and an immediate post operative reduction of mPAP > 37mmHg may predict normalization of RV-PA coupling.

Perception of stress among healthcare workers in hospitals in Belgrade during COVID-19 pandemic

Abstract Background The COVID-19 pandemic has affected healthcare institutions and workers, exposing them to unfamiliar and hazardous conditions, increased workloads, and changing directives. This has led to work-related stress, resulting in burnout, depression, anxiety disorders, and other health issues among healthcare workers. Methods This cross-sectional study utilized an anonymous questionnaire with closed-ended questions. To assess stress levels among healthcare workers, a Likert-type scale was used. Over 6.000 healthcare workers completed the questionnaire in 2022. The relationship between the dependent variable (perceived stress level) and predictors was modelled using generalized ordinal univariate and multivariate logistic regression. Results Almost a third (30.7%) of respondents felt a very high amount of tension, stress, or pressure while performing their jobs under the conditions of the COVID-19 epidemic, while 422 (6.8%) did not feel tension, stress, or pressure at all. In the multivariate logistic regression model, statistically significant predictors of higher levels of perceived stress in the conditions of the COVID-19 epidemic include female sex (OR = 0,80), older age (OR = 1.19), being in a managerial position (OR = 1.32), lower satisfaction with available work time (OR = 0.82), patient relations (OR = 0.81), financial compensation (OR = 0.83), and cooperation with colleagues (OR = 0.93). Conclusions Through the identification of potential stress predictors, valuable insights are gained to aid policymakers in the planning and enhancement of healthcare personnel’s work during pandemics, as well as in situations characterized by heightened stress levels. Key messages • These findings emphasize supporting healthcare workers during the pandemic. • Strategies for reducing stress should be directed towards healthcare professionals who experience higher stress levels.
