Detection of chronic obstructive pulmonary disease and frequency of cardiopulmonary events in patients with a significant smoking history hospitalised for acute myocardial infarction

Abstract Background Smoking is a major risk factor for chronic obstructive pulmonary disease (COPD) and also myocardial infarction (MI). Patients with COPD are more likely to have MI than those without and adequately treating COPD might improve cardiovascular outcomes. Reliable diagnosis is important for appropriate treatment. Prevalence of COPD in those hospitalised for MI has not been accurately established. Blood eosinophil count is an important guide to the benefit of inhaled corticosteroid (ICS) treatment in COPD. We aimed to accurately characterise lung function, symptom burden, eosinophil count and cardiopulmonary events in those with a significant smoking history hospitalised for acute MI. Methods Participants (n=216) with a smoking history of ≥10 pack-years currently hospitalised for acute MI were recruited at a single UK centre. Microspirometry and completion of the COPD Assessment Test (CAT) questionnaire were performed at enrolment. Presence and severity of COPD was graded using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. A high burden of COPD symptoms was defined as a CAT score of >10. Repeat CAT and assessment for relevant cardiopulmonary events was undertaken at 3 months and 1 year after enrolment. Results In the enrolled cohort, median age was 60 years (IQR 53-67), 26% were female, 57% were current smokers and median pack-year history was 32 (23-45). 41 of 216 (19 %, [95% CI 14-25]) had evidence of COPD, defined as FEV1/FEV6 <0.7 on best-attempt microspirometry, with 39 (95%) being GOLD2 or greater. Of the 41 with detected COPD, only 15 (37%, [22-53]) had a prior diagnosis. In those with evidence of COPD, a high burden of COPD symptoms was present in 63% of participants at enrolment, 40% at 3 months and 45% at 1 year. 20% [9-35] were receiving inhaled corticosteroids at enrolment. 63% [47-78] had eosinophil count ≥100 cells/mm3 and 17% [7-32] ≥300 cells/mm3. Among those with detected COPD, after 1 year 19.5% (95% CI 9-35%) had suffered a respiratory illness requiring prescription of medication, which was numerically but not statistically significantly higher than those without detected COPD (14.3% [10-20%]). In the COPD cohort, death, infection requiring hospitalisation, MI or unplanned coronary revascularisation, and bleeding requiring hospitalisation each occurred on two occasions (4.9%). Conclusions Based on these data, the prevalence of microspirometry-diagnosed COPD of any severity in patients with significant smoking history hospitalised for MI is around 19%. There is a high rate of undiagnosed and untreated disease, a significant burden of symptoms, including during convalescence, and around a 20% incidence of respiratory illness requiring medical treatment at 1 year. Gathering accurate data from this group is helpful in planning research and service improvement. Increasing detection of COPD in patients with MI would lead to improved cardiopulmonary outcomes.

Agenda 2030 for sustainable development in Portuguese Speaking Countries, indicators inequalities

Abstract Background Achieving the SDG Sustainable Development goals represents a major global challenge. The Community of Portuguese Speaking Countries (CPLP) is made up of countries: Angola, Cape Verde, Guinea-Bissau, Equatorial Guinea, Mozambique, São Tomé and Príncipe, Brazil, Portugal, and East Timor. Studies on SDG indicators are little studied among these countries. The study analyzes SDG health indicators in the Community of Portuguese Speaking Countries (CPLP) and their projections for 2030, and investigates the correlation between the countries’ level of development and the performance of these indicators. Methods Ecological epidemiological study. Estimates from the Global Burden of Disease (GBD) study between 1990 and 2021 were analyzed, referring to fifteen indicators: universal health coverage, sanitation, smoking, maternal and child health, vaccination coverage and communicable diseases. The GBD study generated projections by calculating the annual change since 1990 for each country and year and then calculating the weighted annualized rate of change. The correlation between the Sociodemographic Index (SDI) and the SDG indicators was investigated using the Spearman test, at a significance level of 5%. Results The best performances of the analyzed indicators were seen for Portugal, followed by Brazil, Cape Verde and São Tomé and Príncipe. In other countries, high rates of infectious diseases, maternal and childhood mortality, malnutrition, low vaccination coverage and sanitation were observed. There was a negative correlation between the SDI and the indicators of childhood mortality rate (R=-0.82; p < 0.05), malnutrition (R=-0.7; p < 0.05), incidence of tuberculosis (R =-0.73; p < 0.05) and positive between SDI and sewage coverage (R=-0.83; p < 0.05). Conclusions The CPLP presents internal differences regarding the health indicators analyzed, making it essential to advance cooperation between countries to achieve the SDG targets in 2030. Key messages • There are great inequalities between SDG indicators in Portuguese-speaking countries. • It is important to advance technical cooperation between countries to formulate solutions and leave no one behind.

Infectious disease prevention among internally displaced people: Perspectives from Lviv, Ukraine

Abstract Background The ongoing war in Ukraine has increased the risk of infection spikes, especially among internally displaced people. The healthcare challenges in the war context necessitate teaching the population of preventative measures, which have become the primary vector of the activities of the Ukrainian Regional Centers for Disease Control and Prevention. Objectives The research aimed to highlight the activities of the Lviv Regional Center for Disease Control and Prevention (CDC) in relation to internally displaced people. Methods The research project analyzed the incidence rate of infectious diseases and vaccination coverage data among the population and internally displaced people in the region. The data were collected from monthly reports of CDC’s departments and alert messages sent by primary care institutions to the CDC. Results According to the Single register of internally displaced people (IDP), 13% of internally displaced people were permanently staying in the Lviv region (the second place was Zakarpattia region - 9% of IDP, and the third was Kyiv - 7% of IDP). In the Lviv region, 237,000 people registered as forcibly displaced. Total, over 700, 000 people are in the area, including the unregistered and 68,000 children. In 2022-2023, the morbidity rates among IDPs did not exceed the rates among the general population in the area. Each IDP residence place had its physician; 11 thousand IDPs were vaccinated, and 3,235 of those were children. In general, 46 mobile medical brigades worked on-site in the Lviv region. Only one spike of gastrointestinal infection was registered. CDC employees provided lectures and workshops on hygiene and food storage in 56 IDP residence places. Conclusions The review results show that coordination between CDCs, local physicians, and mobile medical brigades in the IDP residence areas prevents outbreaks of infectious diseases and swiftly responds to emerging threats. Key messages • The tragic events in Ukraine resulted in healthcare access issues. Lviv CDC, fighting at its own forefront, quickly assessed the risks and efficiently managed the potential hazards. • The Lviv region remains one of the biggest hubs in Ukraine for the temporary residence of internally displaced people, with CDC employees ensuring that preventive measures are effectively carried out.

Incidence of cardiovascular diseases among breast cancer patients: a nationwide registry study 2013-2020

Abstract Background and aims There is evidence to suggest that breast cancer (BC) treatment is associated with an increased risk of developing cardiovascular disease (CVD). Several countries have introduced clinical measures to reduce the impact of breast cancer treatment on cardiovascular function including activated breathing control during radiotherapy, lower radiation doses, and maximum anthracycline doses. The overall aim of this study was therefore to investigate whether breast cancer patients still exhibit higher rates of cardiovascular disease than the general population. Methods We conducted a registry-based cohort study using linked data from four nationwide health registries. Out study population included all Norwegian patients diagnosed with BC between 2013-2020 and matched them by age to 10 controls without BC. Health outcomes were measured from 2008 to 2021. We estimated the cumulative incidence from index date, for ten selected CVDs. For BC patients, the index date was defined as date of BC diagnosis. For controls, the index date was defined as the date of BC diagnosis for the matched BC patient. A wash-out period of 5 years was applied to identify incident cases of CVD. Results The study population included 27,535 patients with BC and 269,9994 matched controls. Median age in both groups was 62 years (IQR: 20). Prior to index date, there were no significant differences in the prevalence of heart valve disease, chronic ischemic heart disease heart failure and peripheral vascular disease in BC patients compared to controls (p>0.05) (Table 1). Hypertensive heart disease, pulmonary embolism, atrial fibrillation, and other cardiac arrythmias were more prevalent in BC patients, while angina pectoris and acute myocardial infarction were more prevalent among controls. After the index date, the incidence proportion for heart valve disease, hypertensive heart disease, pulmonary embolism, atrial fibrillation, other cardiac arrythmias, and heart failure were higher in BC patients compared to controls (p<0.001) (Table 2). No significant differences were found for angina pectoris, acute myocardial infarction, chronic ischemic heart disease, and peripheral vascular disease. Conclusion Breast cancer is still associated with an increased risk of developing several CVDs in current clinical practice, compared to matched controls without breast cancer.Baseline characteristicsIncidence of CVD

Risk factors of 30-day mortality following cardiac surgery in adults with congenital heart disease: analysis from the Japanese registry

Abstract Background With advancements in pediatric therapies, the adult congenital heart disease (ACHD) population has grown consistently. ACHD patients often face complications necessitating cardiac surgery, and understanding surgical risk factors is essential. Purpose This study aims to assess ACHD surgical risk factors using big data, addressing evidence gaps in previous research limited to univariate analysis due to few perioperative adverse events. Methods We analyzed the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC) database from April 2013 to March 2020. The JROAD-DPC database covers nearly all teaching hospitals with cardiovascular beds participation in JROAD. Our study included ACHD patients (>15 years) undergoing open-heart surgery. Our primary outcome was 30-day mortality. We assessed clinical backgrounds, admission status, treatment, and length of hospital stay. Results Out of 13,677 ACHD patients (mean age: 53 years, females 47%) undergoing cardiac surgery assessed for 30-day mortality, 13,516 (98.8%) patients were categorized into the survival group and 161 (1.2%) into the death group. Mortality rates varied by complexity of congenital heart disease (CHD): 0.8% for simple, 1.8% for moderate, and 0.9% for great. The figure shows that a significant increase in 30-day mortality rates with age was demonstrated in simple and moderate complexity (p<0.001 for trend analysis in both categories). In contrast, for cases of great complexity, the increase in 30-day mortality rates with aging was not statistically significant (p=0.443). The death group was significantly older and had higher rates of ambulance admissions, renal disease, and peripheral vascular disease. Intra-aortic balloon pumps (IABP), veno-arterial extracorporeal membrane oxygenation (VA-ECMO), and dialysis during hospitalization were significantly higher among deceased patients. Length of ICU stay was significantly longer in the death group (median [IQR]; 3 [2-4] vs. 6 [3-11], p<0.001). Cox proportional-hazards model showed that age, moderate complexity, emergency admission, hospital bed counts, renal disease, and use of IABP and VA-ECMO were independently associated with 30-day mortality (Table). Conclusions The present study, which utilizes the nationwide administrative DPC database, demonstrates that surgical outcomes for patients with ACHD, as measured by 30-day mortality rates, are generally favorable. These outcomes significantly depend on factors such as age, complexity of CHD, emergency admissions, hospital capacity, renal disease, and use of mechanical circulatory support.

Main challenges and measures taken by public health institutions in response to war in Kyiv Region

Abstract Background The establishment of martial law due to Russia’s military aggression against Ukraine led to specific adjustments in the functioning of the Centers for Diseases Control and Prevention (СDС). The negative impact of hostilities is determined by the increased morbidity rate of communicable and non-communicable diseases, insufficient supply of safe drinking water and food to damaged sites, inadequate living conditions, etc. Objectives The purpose of the work was to create an effective system for responding to biological, chemical and radiation hazards and eliminating the consequences of an emergency situation in the realities of martial law. Methods We used the most common methods, namely descriptive, statistical, microbiological and сhemical laboratory tests. Results The activities of the CDC under martial law include daily monitoring studies of environmental objects. The epidemic situation of acute intestinal infection (AII) and other communicable diseases (CD) is constantly analyzed. The Kyiv Oblast CDC became the basic institution for the implementation of the ‘pilot project’ in the direction of sanitary and epidemic assessment and monitoring of environmetal objects in 188 de-occupied areas. The main public health risks were identified: providing the population with high-quality drinking water; low immunization rate of the population; sites for the location of internally displaced persons; natural foci of especially dangerous diseases, such as tularemia, leptospirosis, infection fevers, etc. In 2022, the overall level of CD in the Kyiv region decreased by 44.0% from 2021. The most common nosologies were acute respiratory viral infections and influenza (98.9%), AII (42.4%), tuberculosis (15.3%), Lyme disease (15.3%), and viral hepatitis (14.2%). Conclusions Based on the research conducted, mechanisms have been developed for responding to hazards of various origins by public health institutions, including risk assessmant and laboratory studies. Key messages • The main focus of the Centers for Diseases Control and Prevention is aimed at effective response to hazards of various origins in order to ensure public health under martial law. • Risk assessment in de-occupied territories has become an important tool for identifying correct approaches to prevent negative consequences for public health.

Prognostic role of right ventricular-pulmonary artery coupling assessed by TAPSE/PASP ratio in patients with heart failure and mildly reduced ejection fraction

Abstract Background The development of right ventricular (RV)-pulmonary arterial (PA) coupling has resulted in a novel and comprehensive index for evaluating RV function in relation to the underlying RV afterload. In patients with heart failure (HF), it is acknowledged that RV-PA uncoupling are features that are associated with poor outcome. The RV-PA coupling index can be readily assessed non-invasively using the ratio of two standard echocardiographic measurements: tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP). However, few studies have defined the prognostic impact of the TAPSE/PASP ratio in patients with HF and mildly reduced EF (HFmrEF). Methods From the prospective cohort study of 1,410 hospitalized HF patients (age 68+/-15, men 62%) between August 2015 and September 2019, this study enrolled 191 HFmrEF (i.e., left ventricular ejection fraction (LVEF) 41–49%) patients whose TAPSE and PASP were measured during hospitalization and discharged alive. We studied the prognostic impact of TAPSE/PASP ratio on HFmrEF patients using by cut-off value obtained from receiver operating characteristic (ROC) analysis. The primary and secondary endpoints was defined as the all-cause death and HF re-hospitalization after discharge, respectively. Results During median follow-up of 38 [23–52] months, 48 patients (25%) died. The deceased patients had a significantly older (median 75 vs. 71 years, p<0.05), higher rate of ischemic heart disease (50% vs. 23%, p<0.05), elevated brain natriuretic peptide levels (325 vs. 159 pg/ml, p<0.05) and lower rate of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (65% vs. 80%, p<0.05) at discharge. In the ROC analysis, the cut-off value of TAPSE/PASP ratio for mortality was 0.46. Patients with TAPSE/PASP ≤0.46 had a significantly higher all-cause mortality (log-rank p<0.05) and had a tendency of higher rate of HF re-hospitalization than patients with TAPSE/PASP >0.46 (log-rank p=0.06) (Figure). Using multivariate analysis, the lower TAPSE/PASP ratio had an independent predictive value of prognosis in patients with HFmrEF (hazard ratio 2.16, 95% confidence interval; 1.08–3.92, p<0.05) (Table). Conclusion The TAPSE/PASP ratio has a significant prognostic value in patients with HFmrEF. The RV-PA uncoupling assessed by TAPSE/PASP ratio might be useful for risk assessment in patients with HFmrEF.

Double product derived from exercise stress echocardiography (ESE) or dobutamine stress echocardiography (DSE) in patients with a history of breast cancer and radiotherapy (RXT) exposure and MACE

Abstract Background Breast cancer survivorship has markedly improved in the last two decades due to improved therapies. Among these, adjuvant chest radiotherapy stands out as an integral part of the current treatment. Chest radiotherapy can trigger accelerated atherosclerosis, which, coupled with cardiovascular (CV) risk factors common to this population, can lead to increased rates of coronary artery disease (CAD). ESC 2022 guidelines have established both Exercise Stress Echocardiography (ESE) and Dobutamine Stress Echocardiography (DSE) as cost-efficient and reliable tools for screening this patient population. Recommendations include ESE or DSE 5 years after radiotherapy as a screening tool. Double product (DP), an index common to both tests, parallels myocardial oxygen consumption. It has been used to predict major adverse cardiovascular events (MACE) in other cohorts. Purpose We sought to evaluate if DP could be used as a prognostic indicator for MACE (myocardial infarction, stroke, cardiovascular death, and heart failure) in this population. Methods Breast cancer patients treated with adjuvant radiotherapy from 2000 to 2022 were included. ESE or DSE was done after a mean of 5.4 years (1Q-2.2, 3Q-7.5) post-radiotherapy. Uni and multivariable adjusted Cox regression models were performed to evaluate the association between DP quartiles achieved and the risk of MACE in DSE and ESE groups. MACE-free survival among different quartiles was plotted with the Kaplan Meier method. Results 696 patients were included, with a mean age of 65 (SD 10.0) and 72 (SD 9.4) in ESE and DSE respectively. 61% of patients had ESE. In ESE, we observed increased rates of MACE in the 1st quartile when compared to the other quartiles (Figure 1a). On the other hand, univariate and multivariate Cox models established that for every increase of 1000 units of DP achieved during ESE, there is a risk-reduction of 9% [HR=0.91 (0.86-0.95); p=<0.01] in the future incidence of MACE, thus establishing DP as a protective marker. Additionally, advanced age was shown to be a major risk factor as well [HR=4.58 (1.91-10.9); p=<0.01]. In the DSE cohort however, the development of MACE was equally distributed across DP quartiles even after adjusting for existing comorbidities (Figure 1b). Cox analysis did not establish DP as a prognostic tool in this cohort (Table 1). Conclusion DP is established as an excellent prognostic tool for the detection of MACE in patients who underwent ESE. Patients who achieve higher DP quartiles during these tests have lower future rates of MACE. Regarding DSE, DP is not a good prognostic tool. This could be explained by higher burden of cardiovascular risk factors in this patient population. ESE should be recommended when possible.

Health impact of the Serious Accidents Punishment Act in Korean occupational settings

Abstract Background Interrupted time series analysis serves as a valuable study design for assessing the efficacy of public health interventions implemented at a specific moment in time at the population level. We aim to elucidate the effects of the Serious Accidents Punishment Act implemented in February 2021 in Korea by analyzing changes in the incidence rates of occupational diseases. Methods The monthly data from patients with occupational diseases was extracted from the National Health Insurance Service Cohort database from 2011 to 2023. An Interrupted time series analysis with Poisson segmented regression was used to compare the rates before and after the Serious Accidents Punishment Act introduction in both outpatients and inpatients. Adjustments or stratification variables included sex, age, company size, and injury-related international classification of diseases codes (Injury, poisoning, and certain other consequences of external causes, S00-T88). Results Based on injury rates, men’s inpatient injury rates remained stable, but outpatient rates decreased after the act implementation, while women’s injury rates consistently declined in both inpatient and outpatient settings. The Interrupted time series regression analysis indicates that the Serious Accidents Punishment Act led to a significant reduction in both outpatient and inpatient injury rates for men and women, with a marked decline in outpatient rates and hospital admissions among women post-intervention. Conclusions The Interrupted time series regression results suggest that the Serious Accidents Punishment Act has been effective in reducing injury-related healthcare usage, highlighting the necessity of gender-specific interventions and the potential impact on lowering inpatient visits, although causality remains uncertain without further analysis. Key messages • The Serious Accidents Punishment Act significantly reduced occupational injury rates in Korea, especially among women, demonstrating effective public health intervention. • Interrupted time series analysis reveals Serious Accidents Punishment Act’s impact on reducing healthcare usage for occupational injuries, highlighting the need for gender-specific approaches.

Real-world evidence for patient phenotypes in heart failure with preserved ejection fraction

Abstract Background Heart failure (HF) with preserved ejection fraction (HFpEF) presents a high mortality risk due to its heterogeneous and multifactorial nature, coupled with limited treatment options. The incompletely understood pathophysiology is influenced by various comorbidities, resulting in different clinical phenotypes. Identifying these could be crucial for tailored HFpEF treatments. While previous studies focused on small, well-characterized patient populations, electronic health records (EHRs) offer the potential to unveil HFpEF phenotypes in larger real-world patient groups. Purpose We aimed to establish a sizable, unselected HFpEF patient population using real-world data. Employing cluster analysis, we intended to uncover distinct groups with varied disease aetiology and medical needs based on comorbidity profiles and prognoses. Methods From EHRs of n = 1,610,101 HF patients, we identified an HFpEF cohort of n = 32,009 patients, by applying thresholds for the LVEF and data availability, and by excluding confounding conditions. Clustering by the relative frequency of common comorbidities aimed to reveal patient populations with unique prognoses, comorbidity profiles, and clinical and demographic characteristics. Results Six clusters of different sizes, comorbidity prevalence, clinical presentation, and all-cause mortality were identified. About 50% of patients (n = 15,445) were predominantly hypertensive, with varying extents of coronary heart disease and diabetes mellitus (DM), and a 5-year mortality of about 30%. Around 22% (n = 7,089) exhibited a cardiometabolic comorbidity profile, with an increased prevalence of obesity and sleep apnea, but also DM and hypertension, and a 5-year mortality of 22.5%. Over 15% of patients (n = 5,298) had a 5-year mortality rate of 45.0%, marked by highest rates of anaemia and chronic kidney disease (CKD) but also DM, elevated N-terminal prohormone of brain natriuretic peptide levels, and a reduced estimated glomerular filtration rate. Conclusion Despite the favourable prognosis, a significant proportion of patients represent a cardiometabolic HFpEF phenotype with notable unmet medical needs regarding cohort size and multimorbidity. Patients simultaneously suffering from CKD, anaemia, and the highest mortality rates may represent a previously underrecognized phenotype. Our study demonstrates that distinct medical needs can be identified in a large, unselected real-world HFpEF cohort. In contrast to clinical trials, this approach enabled access to a broader patient population, revealing novel phenotypes to be targeted by precision medicine in the future.

Causes and predictors of long-term mortality in patients referred to a cardiac rehabilitation program

Abstract Introduction Cardiac rehabilitation (CR) programs have proven to reduce short-term mortality in patients with ischemic heart disease (IHD) and hospitalization rates in patients with heart failure (HF) (1-3). However, there is insufficient evidence about long-term mortality (>24-36 months) for patients receiving treatments based on recent clinical practice recommendations. Purpose To assess the long-term prognosis and predictors of mortality in a heterogenous group of patients referred to cardiac rehabilitation, and to obtain a detailed overview of death causes. Methods An inferential analysis of consecutive patients referred for exercise-based CR at a single site between January 2016 and January 2021 was performed. Included subjects were classified attending to four indications for referral: IHD, HF, valvular heart disease (VHD) and cancer therapy-related cardiovascular toxicity (CTR-CVT). Patients who did not initiate the CR program or were referred for other indications were excluded. The primary endpoint was all cause death. The secondary endpoint was cardiovascular (CV) death. A survival analysis was performed using Kaplan Meier estimates for each referral indication and a Cox proportional hazards model was fitted to investigate mortality predictors. The initiation of the exercise program was considered the inclusion date, and patients were followed until they met the primary endpoint or censored by January 2024. Results A total of 1180 patients were included in the analysis (81% male, mean age 61 ± 11 years), with a median follow-up of 5.3 years. Most of the patients had been referred due to IHD (87%), while the proportion for HF, VHD, and CTR-CVT was 9.9%, 1.8% and 1.4%, respectively. Seventy-eight patients (6.6%) died during follow-up, with a Kaplan-Meier estimated survival of 94.5% at 5 years (95% CI 93.2%-95.9%). Nineteen patients (24.4%) died due to a cardiovascular event, mostly sudden cardiac death (47%). The predominant non-CV causes of death were infectious disease (36%) and cancer (34%). A multivariate Cox model analysis (Table 1) showed an increased risk of all cause death for patients referred due to HF (HR 2.95, 95% CI 1.33 - 6.55), VHD (HR 5.55, 95% CI 1.19 - 25.9) and CTR-CVT (22.47, 95% IC 7.32 - 68.95) when compared to IHD (Figure 1). Other significant predictors of mortality were LVEF <40%, male sex, age, diabetes, peripheral vascular disease, and multivessel coronary disease. Only LVEF <40%, VHD, CTR-CVT and peripheral vascular disease were independent predictors of CV death. Conclusion Patients who initiated an exercise-based CR program had a low risk of all cause death at 5 years. Indications for CR other than IHD were associated with higher mortality rates after adjusting for confounder variables, likely due to a selection bias of patients in advanced stages of the disease.Table 1.Cox models for all-cause deathFigure 1.KM plot for all-cause death

Real-world analysis of transcatheter aortic valve replacement in patients with prostate cancer and severe aortic stenosis

Abstract Background Patients with prostate cancer have a high prevalence of cardiovascular disease, including degenerative heart valve diseases such as aortic stenosis. It is not uncommon in clinical practice to perform transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis and active prostate cancer. Still, the prognosis after this procedure in this population is not well known. Purpose To evaluate 1-year and 3-year survival rates after TAVR in patients with prostate cancer who have undergone TAVR when compared with patients without active cancer. Methods Data were extracted from electronic medical records of a large multinational collaborative network (TriNetX) that currently englobes 113 healthcare organizations worldwide with more than 100 million patients. Patients aged 18 years or older with prostate cancer documented up to 12 months before TAVR as well as controls undergoing TAVR without oncologic history before the proceeding were included. The survival analysis for 1 year and 3 years was performed with Kaplan Meier survival plots and log-rank test. Propensity score matching, using clinical and demographic variables, was performed to pair the cohorts. Results From a cohort of 26,656 men who had undergone TAVR, we identified 1,040 with prostate cancer diagnosed up to 1 year before TAVR ( prostate cancer group) and 20,231 patients without oncologic history before TAVI (control group). After propensity score matching, analyzing 1,040 patients in each group, the 1-year and 3-year survival probabilities were not different between the prostate cancer group versus the control group ( 89.5% vs 88.9%, log-rank test P=0.70 and 72.6% vs 68.7%, log-rank test P=0.22, respectively). Considering a subgroup of patients with metastatic prostate cancer ( n=229) under androgen deprivation therapy vs the control group ( n =229), we have also not observed a survival difference between the two groups at 1-year and 3-year follow-up ( 88.1 vs 89.1%, log-rank test P=0.69 and 58.7% vs 67.4%, log-rank test P=0.25). Conclusions In this real-world analysis, patients with prostate cancer and severe aortic stenosis who underwent TAVR, including patients with metastatic disease, the 1-year and 3-year survival rates were not significantly different when compared to patients without oncologic hystory who underwent TAVR.

Clinical significance of MRI-measured olfactory bulb height as an imaging biomarker of idiopathic Parkinson's disease.

This study aimed to determine whether the olfactory bulb height (OBH) measured using magnetic resonance imaging (MRI) has clinical utility as an imaging biomarker in the evaluation of patients with idiopathic Parkinson's disease (iPD) through its correlation with movement impairment. This retrospective study included cognitively intact patients with suspected parkinsonism. All participants underwent T2-weighted imaging to measure OBH. Logistic regression was used to determine whether OBH was an independent risk factor for distinguishing iPD patients from disease controls, and its relation with clinical parameters related to motor impairment, including clinical laterality, modified Hoehn and Yahr (HY) stage, and Unified Parkinson's Disease Rating Scale (UPDRS) III score, was investigated. Based on the final clinical diagnosis, 79 patients with iPD and 16 disease controls were included. The mean OBH was significantly smaller in iPD than in disease controls (p < 0.0001). OBH was a significant independent predictor of iPD, with a cutoff of 1.52 mm. In the comparison among the ipsilateral, contralateral side of iPD with clinical laterality, and disease control group, the OBH of the disease control group was significantly larger than both the ipsilateral and contralateral sides (P < 0.05). However, there was no significant difference in OBH between the ipsilateral and contralateral sides (p > 0.05). OBH according to HY stage was significantly smaller in HY stage 2-3 groups than in the disease control group (p < 0.001). The correlation analysis between UPDRS III and OBH showed a mild negative correlation (r = -0.32, p = 0.013). MRI-measured OBH is decreased in iPD regardless of age and sex and may be correlated with the progression of motor symptoms in the iPD.

Temporal and Spatial Dynamics of Anthracnose (Colletotrichum sublineolum) Disease on Selected Sorghum Genotypes at Assosa Zone, Western Ethiopia

Background Over 500 million people worldwide rely on sorghum as a main food crop. About 10% of the daily caloric intake of households in Ethiopia’s northwest and eastern regions, including Benishangul Gumuz, comes from sorghum. A hemi-biotrophic fungal pathogen called Colletotrichum sublineolum caused anthracnose disease is among the biotic constraints of sorghum production. Methods Ten selected sorghum genotypes were assessed for sorghum anthracnose severity and its temporal and spatial dynamics on field plots in the districts of Assosa and Bambasi. The performance of the chosen sorghum genotypes was assessed using the following metrics: AUDPC, disease progress rate, yield-related trait, sorghum grain yield, and mean severity index. Anthracnose severity was evaluated using a 1–5 disease rating scale and assessments conducted at seven consecutive time points. Results Ten genotypes of sorghum were examined in the districts of Assosa and Bambasi, with mean anthracnose severity index ranging from 60-77 PSI and 53-82 PSI, respectively. AUDPC varied from 351 to 470 % days and 316 to 499 % days at Assosa and Bambasi districts, respectively. Bambasi district achieved a larger grain yield than the Assosa district. Assosa-1 demonstrated a significant level of disease pressure, yet the current investigation found that this genotype is the highest performing genotype in both locations. Conclusions There is a considerable positive link between the severity of anthracnose and the weekly total rainfall and relative humidity. At both trial sites, Mersa-1 continuously produced higher grain yields and reduced disease levels. Breeders might utilize the Baco Striga sorghum genotype as a check line in a breeding effort to resist anthracnose disease because it shown a high vulnerability to the disease at both locations.

Comparative characteristics and invasive management in patients with non-ST elevation acute coronary syndromes in two high-volume hospitals from Romania and Germany

Abstract Introduction Cardiovascular disease (CVD) carries the highest mortality burden across Europe, acute coronary syndromes (ACS) being responsible for most CVD-related deaths. However, significant regional differences in ACS management have been reported. Purpose To describe the characteristics and management of patients with higher-risk non-ST elevation ACS (NSTE-ACS) in 2 high-volume hospitals from 2 European countries with different prevalence of CVD and different income (Germany – GER and Romania – RO). Methods All consecutive invasively managed high and very-high risk NSTE-ACS patients admitted in 2022 in two high-volume hospitals from GER and RO were identified. Patient clinical profiles, coronary anatomy, revascularization strategies, and in-hospital outcomes were compared. Results were adjusted for age and gender. Results 707 patients (345 GER, 66.7% male; 362 RO, 71.5% male; p&amp;gt;0.05) were included. RO patients were younger (65.5 vs. 70.1 years), with higher rates of hypertension (88.7% vs. 82.0%), dyslipidemia (95.6% vs. 81.7%), diabetes (46.1% vs. 34.5%), and active smoking (37.3% vs. 23.5%) (all p&amp;lt;0.05); whereas GER patients had higher rates of atrial fibrillation (36.2% vs. 23.2%), chronic respiratory disease (24.6% vs. 10.5%), sleep apnoea (9.0% vs. 1.4%), thyroid disorders (24.1% vs. 6.4%), and prior revascularization by percutaneous coronary interventions (PCI) (36.5% vs. 20.2%) or coronary artery bypass grafting (CABG) (15.7% vs. 3.0%) (all p&amp;lt;0.05). Mean left ventricular ejection fraction (LVEF) was lower in the RO cohort (43.4% vs. 48%, p&amp;lt;0.001). Rates of myocardial infarction diagnosed by high-sensitivity troponin I assays (88.7% GER, 87.6% RO), and median diagnosis-to-cathlab intervals (12.8 hours GER, 15.5 hours RO) were similar (all p&amp;gt;0.05). In the obstructive coronary artery disease (CAD) group (80.3% GER, 84.3% RO), no differences were found in multivessel disease rates (67.1% GER, 69.8% RO) or mean SYNTAX score (18.6 GER, 16.9 RO) (all p&amp;gt;0.05). For type 1 NSTE-ACS (67% GER vs. 79% RO, p&amp;lt;0.001), PCI represented the main revascularization method (88.3% GER vs. 78.3% RO, p&amp;lt;0.05). Excluding patients with prior CABG undergoing PCI, complete revascularization (residual SYNTAX score ≤8), was reported in 77.1% GER and 84.4% RO of the PCI cases (p&amp;gt;0.05). Intravascular imaging was used in 28.4% of PCIs in GER, and in none in RO. In-hospital mortality (7.0% GER, 6.8% RO), and rates of major adverse cardiovascular events, defined as a composite of death, myocardial infarction, and stroke (8.1% GER, 9.1% RO), were similar (all p&amp;gt;0.05). Conclusions Higher-risk NSTE-ACS patient profiles mirror overall country CVD risk patterns. Compared to Germany, patients in Romania are younger, with a higher CVD risk factor burden, lower LVEF, underdiagnosis of major non-CVD comorbidities, and delayed CAD diagnosis. Despite similar guideline-directed management and in-hospital outcomes in both centres, these aspects may influence the long-term prognosis.

A marker of systemic inflammation in hidradenitis suppurativa patients without cardiovascular disease: aortic arch calcification.

In this study, we aimed to investigate whether there is a relationship between aortic arch calcification (AAC) and hidradenitis suppurativa (HS) in HS patients without cardiovascular disease. In this study, patients over 18 years of age who applied to the dermatology outpatient clinic between January 2023 and February 2024 were followed up with the diagnosis of HS without cardiovascular disease, and a healthy control group matched in terms of age and gender were included retrospectively. In total, 130 patients with HS without cardiovascular disease and 130 control patients were included in the study. AAC was significantly higher in the HS group compared to the control group (p = 0.028). In the multivariate analysis, we found that age and HS were independent predictors of AAC (OR: 1.048 (1.009-1.089); p = 0.015, OR: 3.158 (1.181-8.445); p = 0.022, respectively). When we divided the groups as having AAC (grade 1-3) and not having AAC (grade 0), the rate of HS disease was significantly higher in the group with AAC compared to the group without AAC (75.0% vs. 47.5% p = 0.010). AAC is observed more frequently in patients with HS without cardiovascular disease than in healthy individuals. Moreover, HS can be considered as an independent predictor of AAC. AAC may contribute to developing treatment strategies in HS patients without cardiovascular disease.

Changes in serum uric acid, glutathione, and amyloid-β1-42 levels in Parkinson’s disease patients and their association with disease progression and cognitive decline

Objective This study aims to evaluate the diagnostic significance of serum uric acid (UA), glutathione (GSH), and amyloid-β1-42 (Aβ1-42) levels in relation to disease progression and cognitive impairment in patients with Parkinson’s disease (PD). Methods A total of 209 PD patients with disease duration ranging from 4.0 to 6.8 years were enrolled. Based on the Hoehn-Yahr staging system, patients were classified into Early (n = 67), Medium-term (n = 70), and Advanced (n = 72) stages. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), dividing the cohort into CD (cognitive dysfunction, n = 94) and NO-CD (no cognitive dysfunction, n = 115) groups. Serum UA, GSH, and Aβ1-42 levels were analyzed for correlations with clinical data. Independent risk factors and diagnostic value were determined through multivariable logistic regression models and receiver operating characteristic curve analysis. Results Serum UA and GSH levels progressively declined with advancing disease stage, while Aβ1-42 increased. Compared to the NO-CD group, the CD group showed lower serum UA and GSH levels, and higher Aβ1-42 levels. Serum UA and GSH were inversely correlated with disease duration, levodopa equivalent daily dose, and Unified Parkinson's Disease Rating Scale scores, while Aβ1-42 showed positive correlations. UA (p = 0.006), GSH (p < 0.001), and Aβ1-42 (p = 0.040) were independent predictors of disease stage. Similarly, UA (p = 0.003), GSH (p < 0.001), and Aβ1-42 (p < 0.001) were independent predictors of cognitive dysfunction. The combined assessment of these markers demonstrated a higher area under the curve (AUC) than individual markers for disease and cognitive decline identification. Conclusions Serum UA, GSH, and Aβ1-42 are independent predictors of disease progression and cognitive decline in PD patients. Their combined use offers enhanced diagnostic accuracy for disease staging and cognitive impairment in PD.

Incidence rates of hepatocellular carcinoma based on risk stratification in steatotic liver disease for precision medicine: A real-world longitudinal nationwide study.

Detailed subgroup incidence rates for steatotic liver disease (SLD)-related hepatocellular carcinoma (HCC) are critical to inform practice and public health interventions but remain sparse. We aimed to fill in this gap. In a retrospective cohort study of adults with SLD from the United States (US) Merative Marketscan Research Databases (1/2007 to 12/2021), we estimated HCC incidence stratified by sex, age, cirrhosis, diabetes mellitus (DM), and a combination of all these 4 factors. We excluded patients with significant alcohol use and chronic viral hepatitis. We analyzed data from 741,816 patients with SLD (mean age 51.5 ± 12.8 years, 46% male, 14.7% cirrhosis). During a 2,410,166 person-years (PY) follow-up, 1,740 patients developed HCC. The overall HCC incidence yielded 0.72 per 1,000 PY (95% confidence interval [CI, 0.68, 0.75]). The incidence was higher in males (0.95, 95% CI [0.89, 1.01]) compared to females (0.52, 95% CI [0.48, 0.56]) (p < 0.001). For those with cirrhosis, the incidence was significantly higher at 4.29 (95% CI [4.06, 4.51]) compared to those without cirrhosis (0.14, 95% CI [0.13, 0.16]) (p < 0.001). Additionally, the incidence was higher in patients with DM (1.19, 95% CI [1.12, 1.26]) compared to those without DM (0.41, 95% CI [0.38, 0.44]) (p < 0.001). Chronic kidney disease (CKD) was also associated with a higher HCC incidence of 2.20 (95% CI [2.00, 2.41]) compared to those without CKD (0.58, 95% CI [0.55, 0.62]) (p < 0.001). Similarly, individuals with cardiovascular disease (CVD) had a higher HCC incidence of 1.89 (95% CI [1.75, 2.03]) compared to those without CVD (0.51, 95% CI [0.48, 0.54]) (p < 0.001). Finally, the incidence of HCC was significantly higher in patients with non-liver cancer (3.90, 95% CI [3.67, 4.12]) compared to those without other cancers (0.29, 95% CI [0.26, 0.31]) (p < 0.001). On further stratification, HCC incidence incrementally rose by 10-year age intervals, male sex, cirrhosis, and DM, reaching 19.06 (95% CI [16.10, 22.01]) and 8.44 (95% CI [6.78, 10.10]) in males and females, respectively, but only 0.04 for non-diabetic, noncirrhotic aged <40 years patients in both sexes. The main limitation of this methodology is the potential misclassification of the International Classification of Diseases (ICD) codes inherent in claims database studies. This nationwide study provided robust granular estimates for SLD-related HCC incidence stratified by several key risk factors. In addition to cirrhosis, future surveillance strategies, prevention, public health initiatives, and future research models should also take into account the impact of sex, age, and DM.

Adjustment Analysis of the Teaching Content of Parasitology Examination in Higher Vocational Colleges

At present, the infection rate of human parasitic diseases has changed greatly in our country, and foodborne parasitic diseases have become the mainstream of human parasitic diseases, among which the more frequent foodborne parasites are a liver fluke, taeniasis, cysticercus, trichinella, toxoplasma gondii and so on. The test methods for parasitic diseases are pathogenetic examination, immunological examination, molecular biological examination and combined diagnosis. Based on the current epidemic characteristics of human parasitic diseases in China and their examination and analysis, the teaching content of the course Parasitology Examination in higher vocational colleges is adjusted, and the main popular human parasitic diseases and their examination methods are listed as the teaching focus, and other parasitic diseases that have been eliminated or reached the control standard are transferred to the familiar or understood teaching content. To make the teaching of medical laboratory technology in higher vocational colleges closer to the needs of vocational posts and improve the adaptability of students to their posts.

Bayesian Model Projecting Cardiovascular Disease Related Mortality Trends in the United States.

As future cardiovascular disease mortality trends have public health implications, we aimed to project ischemic heart disease (IHD), cerebrovascular disease (CeVD), and heart failure (HF) mortality rates for adults (40-79 years). In this population-level study, we linked the yearly mortality rates (per 100 000 US residents) (2000-2019) with IHD, CeVD, or HF as the primary cause of death from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research with the midyear US population estimates (2000-2035) for adults (40-79 years). We calculated the observed age-standardized mortality rates (2000-2019) (per 100 000 residents) (aSMR) and fitted Bayesian age-period-cohort models to project aSMR for IHD, CeVD, and HF up to 2035 in the United States. Between 2019 (last year of observed data) and 2035 (last year of projected results), the US population (40-79 years) will increase by 16% and age. The IHD aSMR will reduce from 111.9 (in 2019) to 81.8 (66.7-96.9) in 2035, an effect observed for all age groups. The CeVD aSMR will remain comparable between 2019 (37.4) and 2035 (38.6 [30.7-46.5]). The HF aSMR will increase from 16.5 in 2019 to reach 30.9 (13-48.8) in 2035; such increases were observed in all age groups. In the United States, between 2020 and 2035, the aSMR for IHD is expected to decrease, for CeVD will remain stable, and for HF will increase substantially. These data can inform resource allocation for future public health initiatives.
