Clinical outcomes following debulking atherectomy of calcified left main coronary lesions: a high-volume centre experience

Abstract Introduction Plaque modifying-debulking (PMD) devices are the most effective initial strategy for percutaneous coronary intervention (PCI) of severely calcified lesions including left main coronary artery (LMCA). There is limited data comparing the short and long clinical outcomes of these devices in LMCA lesions. Methods A retrospective analysis of patients with fibrocalcified LMCA lesions treated with PCI with adjunctive PMD devices at a large centre between 2008 and 2021. The primary study endpoint was long-term mortality at documented longest follow-up. Secondary endpoints included procedural complications and inhospital clinical outcome. Results A total of 302 patients with fibrocalcified LMCA lesions treated with rotational atherectomy (RA; n=240), intracoronary lithotripsy (ICL; n=30) or excimer laser coronary atherectomy (ELCA; n=32) were included. Approximately 55% of all patients presented with acute coronary syndromes. Technical success was achieved in 98.7% of patients and procedural success was achieved in 95.4% of patients. At a median follow-up of 42 [19-62] months, there was no difference in mortality between the 3 PMD modalities (RA 54/240 [23.4%] vs. ICL 1/30 [3.3%] vs. ELCA 5/32 [15.6%], P=0.128). Likewise, in-hospital clinical outcomes were similar. However, procedural complications were significantly higher in the ELCA group. Conclusions In patients with fibrocalcified LMCA lesions treated with PCI, adjunctive PMD devices appear safe with survival excceding 80% at long-term follow-up. Our study suggests that ELCA use may be associated with higher procedural risks however this did not increase in-hospital clinical outcomes or long-term mortality risk.

Cardiovascular mortality rate between 2018 and 2022 in Kyrgyz Republic

Abstract Background Cardiovascular diseases (CVD) are the number one cause of death in low- and middle-income countries (LMICs), including Kyrgyz Republic. According to official statistics, CVD ranks first in the structure of overall mortality, accounting for more than half (52.1% according to 2022 data) of all deaths. Purpose to analyze the cardiovascular mortality rate in the Kyrgyz Republic, from 2018 to 2022. Methods Medical and statistical information on mortality from CVD in the population was obtained from the Centre for Electronic Health (CEH) of the Ministry of Health. To conduct a comparative analysis, relative indicators per 100 thousand population were calculated. A retrospective epidemiological study of mortality from CVD including different nosological forms over period for 2018–2022 was conducted, calculating the rate of increase (decrease). An analysis of the epidemiological situation of the disease in nine administrative-territorial units of the Kyrgyz Republic was also carried out with the calculation of the average 5-year mortality ratefor the period from 2018 to 2022. Results Despite the decrease in morbidity, a high proportion of mortality from CVD remains in all years, more than 50%. In terms of the percentage indicator for recent years, all this time it has maintained the highest position, in contrast to diseases of other organs and systems. In the last decade, from 2012 until 2020, there was a gradual decrease in the mortality rate. Since 2020, we have seen a sharp increase in the CVD mortality rate per 100 thousand population by 19.6% compared to 2018, by 19.4% since 2019, which is associated with the influence of Covid-19 pandemic, in 2021 this indicator amounted to 297.6 cases, in 2022 - 234.5. The main contribution to population death from CVD is made by coronary heart disease (65.90%), including acute myocardial infarction, cerebrovascular diseases (21.4%), arterial hypertension (5.9%). If we analyze the mortality rate from CVD by nine administrative-territorial units, the highest rates in 2022 are observed in the Chui and Talas regions, 291.9 and 266.3 per 100 thousand population respectively; the lowest in the Osh region (207.3), Osh city (196.1) and Bishkek (208.6), which is explained by the better organization of health services in these areas. Conclusion CVD remains the main cause of mortality in the population of the Kyrgyz Republic. Although over the past year there has been a good decline in this indicator, in almost all regions, particularly the greatest successes have been achieved in Naryn and Issyk-Kul regions. In connection with the above, there is requirement for a clear identification of priorities when determining the strategy of treatment and preventive interventions. It is necessary to create an effective National system of care for patients with CVD with a focus on emergency cardiac care and prevention issues.

The Neurological Impact of Continuous Nicotine Exposure in Adolescents

Continuous nicotine exposure during adolescence can have profound implications on the development and well-being of individuals in this critical stage of life. As the prevalence of nicotine use among adolescents continues to be a significant public health concern, understanding the impact of this addictive substance on young minds and bodies is crucial. We explored the various dimensions of nicotine exposure in adolescents, from its effects on brain development and cognitive function to the social, emotional, and educational consequences. By looking into the complexities of adolescent nicotine addiction, we can better comprehend the challenges faced by this vulnerable population and develop potential strategies for prevention and intervention.

Drug-coated balloon versus drug-eluting stent for de novo culprit lesion in acute coronary syndromes: a report from nationwide registry in japan

Abstract Background Randomized trials have demonstrated the non-inferiority of DCB strategy compared to DES strategy for ACS [1-3]. However, generalizability in clinical settings remains unclear. Purpose This study aims to compare the outcomes between drug-coated balloon (DCB) and drug-eluting stent (DES) strategies in percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) within a nationwide procedure-based registry. Methods This is a retrospective analysis of a cohort study from a prospective, nationwide registry from January 2017 to December 2020 in Japan, focusing on ACS patients who underwent DCB or DES strategy for a single de novo lesion. One-year incidence of all-cause death, cardiovascular death, non-cardiovascular death, non-fatal ACS, stroke, and major bleeding events were compared. Subgroup analysis included lesion-based and ST-elevation myocardial infarction/non-ST-elevation ACS stratification. Results Among 5,212 propensity-matched ACS patients, DCB and DES strategies showed no significant differences in one-year incidence of all-cause death (4.5% vs. 4.6%, hazard ratio [HR]: 0.92, 95% confidence interval [CI]: 0.72-1.19), cardiovascular death (2.5% vs. 2.5%, HR: 0.90, 95% CI: 0.64-1.26), non-cardiovascular death (2.0% vs. 2.1%, HR: 0.96, 95% CI: 0.65-1.42), and non-fatal ACS (1.7% vs. 2.0%, HR: 1.04, 95% CI: 0.70-1.54). DCB showed higher stroke occurrence (0.8% vs. 0.3%, HR: 2.33, 95% CI: 1.06-5.08) but lower major bleeding events (1.4% vs. 2.3%, HR: 0.65, 95% CI: 0.43-0.99) (Figure 1). Subgroup analyses did not reproduce these findings (Figure 2). Conclusions ACS patients using the DCB strategy demonstrated clinical outcomes equivalent to those undergoing the DES strategy at one year. Further investigation with an extended follow-up is necessary to confirm these findings.

Co-creating stigma-prevention strategies for mental health interventions with migrant populations

Abstract Background The ADVANCE project aims to address mental health disparities among people in a situation of vulnerability in Europe. Through a co-creation approach, workshops were conducted to devise stigma prevention strategies during the implementation of mental health promotion interventions for migrant populations in Italy and Denmark. Methods The methodology involved two rounds of scenario-based workshops, a participatory method that elicit expert opinions to solve local problems and anticipate future ones. Round 1 included two separate workshops with (1) end-users and umbrella organizations, and (2) healthcare practitioners and decision-makers, to ensure diverse perspectives and minimize the impact of power imbalances. Participants brainstormed strategies to minimize stigma and optimize the intervention scenario. In Round 2, a mixed-group workshop was held to refine the strategies. Workshops occurred in Copenhagen and Verona in March 2024. Content analysis of the data was carried out. Results In Denmark, discussions emphasized tailored presentation of the intervention promoting shared experiences and normalizing mental health challenges, language sensitivity, participation through self-identification, and attention to relational aspects in intervention delivery to combat stigma effectively and enhance acceptability and engagement with the intervention. In Italy, proposed strategies included group exercises to raise awareness and promote open dialogue about cultural differences, language barriers, and discrimination. Discussions also considered the intersectionality of stigma, including factors like gender, socioeconomic status, and sexual orientation. Common themes included language sensitivity, facilitator training, and inclusive and safe spaces. Conclusions Scenario-based workshops can be a valuable tool to facilitate the co-creation of stigma-prevention strategies while involving all stakeholders in promoting effective mental health interventions. Key messages • Co-creation approach fostered stakeholder collaboration, yielding tailored strategies that promote inclusivity, acceptability and engagement with mental health interventions for migrant populations. • Context-specific approaches that emphasize trust, confidentiality and cultural sensitivity were prioritised to tackle stigma when implementing interventions and promoting mental health equity.

Advancing diabetes management: Exploring pancreatic beta-cell restoration’s potential and challenges

Diabetes mellitus, characterized by chronic hyperglycemia due to insulin deficiency or resistance, poses a significant global health burden. Central to its pathogenesis is the dysfunction or loss of pancreatic beta cells, which are res-ponsible for insulin production. Recent advances in beta-cell regeneration research offer promising strategies for diabetes treatment, aiming to restore endogenous insulin production and achieve glycemic control. This review explores the physiological basis of beta-cell function, recent scientific advan-cements, and the challenges in translating these findings into clinical applications. It highlights key developments in stem cell therapy, gene editing technologies, and the identification of novel regenerative molecules. Despite the potential, the field faces hurdles such as ensuring the safety and long-term efficacy of regen-erative therapies, ethical concerns around stem cell use, and the complexity of beta-cell differentiation and integration. The review highlights the importance of interdisciplinary collaboration, increased funding, the need for patient-centered approaches and the integration of new treatments into comprehensive care strategies to overcome these challenges. Through continued research and collaboration, beta-cell regeneration holds the potential to revolutionize diabetes care, turning a chronic condition into a manageable or even curable disease.

Intravascular lithotripsy in the management of underexpanded stents

Abstract Introduction Stent underexpansion significantly heightens the risk of major adverse cardiac events (MACE), and available treatment options for this condition remain limited. Intravascular Lithotripsy (IVL) technology disrupts superficial and deep calcium by using localized pulsative sonic pressure waves, emerges as a promising tool for underexpanded stents. Methods Following PRISMA guidelines, we systematically explored PubMed, SCOPUS, and Cochrane databases up to September 3, 2023, for studies evaluating IVL's safety and efficacy in treating underexpanded stents. We gathered angiographic (QCA) and intracoronary imaging (OCT or IVUS) data, examining the stent's minimal diameter stenosis (MDS), minimal lumen diameter (MLD), minimal stent area (MSA), and minimal lumen area (MLA) pre- and post-IVL application. Procedural success constituted the efficacy endpoint, while peri-procedural complications, in-hospital-30-days and long-term mortality, and MACE were safety endpoints Results This meta-analysis comprised 21 studies including 669 patients and 673 treated lesions in underexpanded stent. The mean age was 73.2 ± 2.1 years, with an overall IVL procedural success rate of 93% [(95% Confidence Interval (CI): 88%-96%, I2=29%), while the in-hospital-30-days and long-term mortality incidence were 1% (95% CI: 1%-3%, I2=0%) and 3% (95% CI: 2%-6%, I2=0), respectively. The 30-days target lesion revascularization (TLR) was approximately 6% (95% CI: 3%-12%, I2=50%). There was a significant increase in the MDS [Standardized Mean Difference (SMD): +50.52%, 95% CI: 39.4-61.6, I2=94%)] and in MSA (SMD: +3.52, 95% CI: 2.47 to -4.58, I2=83%) immediately after IVL application. It was observed a significant increase in MLD (SMD: +1.54, 95% CI: 1.09 to 1.98, I2=95%) and in the MLA (SMD: +3.64, 95% CI: 2.62-4.66, I2=5%). Major procedural and device related complications were 3% (95% CI: 1%-6%, I2=0%) and 1% (95% CI: 0%-2%, I2=85%) respectively. Notably low rates were observed for stent thrombosis (0%, 95% CI: 0%-2%, I2=0%), dissections (1%, 95% CI: 1%-4%, I2=0%), perforations (1%, 95% CI: 1%-3%, I2=0%) and no-reflow (0%, 95% CI: 0%-1%, I2=0%). Conclusions IVL demonstrates promise as a safe and effective strategy for underexpanded stent treatment, characterized by low rates of periprocedural complications. Future prospective studies are now warranted to compare IVL to other lesion preparation strategies.30day All-Cause Mortality after IVL use.Minimum Stent Diameter after IVL use.

Trends in home treatment and early discharge of patients with low-risk pulmonary embolism

Abstract Background A strategy of ambulatory treatment or early discharge (≤ 48 hours) of patients with acute low-risk pulmonary embolism (PE) has been adopted by the most recent guideline recommendations. However, the adoption of such a change of paradigm in PE care in the ‘real-world’ clinical setting, outside the concept of prospective cohort (management) studies, remains unknown. Aims To determine the proportion of patients with PE who fulfill eligibility criteria for home treatment or early discharge, to investigate in how many of them such a management strategy is actually followed, and to discover differences in early complications between early or later discharge among low-risk patients. Methods We used two nationwide databases, the US Nationwide Emergency Department Sample (NEDS) and Nationwide Readmission Database (NRD), to identify patients with low-risk PE (absence of the following at presentation: haemodynamic instability, cor pulmonale, tachycardia, dyspnea, hypothermia, altered mental status, and fulfilment of the Hestia critieria). We investigated the proportion of patients that were discharged entirely at home, or discharged early (hospital stay £ 2 days) and their association with predictor variables. We also studied the 90-day occurrence of venous thromboembolism recurrence and major bleeding. Results From 2016 to 2020, there were 2,099,390 emergency department visits for PE (NEDS Database), with 641,621 (30.6%) classified as low-risk. Home treatment was documented in 20.3% of all cases, with 31.5% of low-risk PE cases being treated at home and an increasing trend over time (Figure 1A). Factors associated with home treatment for low-risk PE included younger age, female sex, and absence of comorbidities; home treatment was more frequent at university hospitals, non-metropolitan hospitals, and those with higher emergency department volumes (Figure 2A). In the NRD Database, there were 1,950,708 PE hospitalizations during the same period with 481,321 classified as low-risk (24.7%). An early discharge strategy was followed in 22.6% of all cases, increasing to 45.9% for low-risk PE admissions, with a rising trend observed from 2016 (Figure 1B). Factors associated with early discharge for low-risk PE included younger age, male sex, and absence of comorbidities; here, university hospitals and metropolitan hospitals were less likely to implement early discharge (Figure 2B). The 90-day incidence of VTE recurrence among low-risk patients was lower with early discharge (1.3% vs. 1.8%, p<0.001), as was major bleeding (1.5% vs. 2.8%, p<0.001). Conclusion Our results reveal an increasing implementation of early discharge and home treatment for low-risk PE across recent years. Factors influencing these strategies are related to demographics and hospital type. Early discharge was associated with favourable outcomes in the real-world setting, thus supporting the results of previously performed prospective cohort studies and randomized trials.Figure 1Figure 2

CXCR3-Flavonoid Interaction: A Novel Therapeutic Approach in Cancer Immunotherapy

Objective: To investigate the interactions between select flavonoids (Luteolin, Quercetin, Apigenin, Kaempferol, and Amorphine) and the CXCR3 receptor, evaluating their potential as novel therapeutic agents in cancer immunotherapy. Methods: Molecular docking simulations were employed to analyze flavonoid-CXCR3 receptor interactions. Comprehensive in silico ADMET analyses were conducted to assess pharmacokinetic properties and toxicity profiles of the compounds. Results: Flavonoids exhibited high-affinity binding to the CXCR3 receptor, with binding affinities ranging from -8.7 to -13.0 kcal/mol. Amorphine demonstrated the highest binding affinity (-13.0 kcal/mol), indicating superior inhibition potential. Luteolin showed optimal ADME characteristics, including favorable oral bioavailability (62%) and blood-brain barrier permeability (log BB -1.911). Molecular docking analyses identified critical amino acid residues (TYR205, TYR308, TRP109, PHE131, and ASN132) in flavonoid-CXCR3 interactions. In silico toxicity predictions suggested low risk profiles for all examined flavonoids. Conclusion: This study provides evidence for the potential of flavonoids as CXCR3 receptor antagonists in cancer immunotherapy. The elucidated molecular interactions and favorable ADMET profiles warrant further investigation of these compounds. Future research should focus on optimization of flavonoid-based CXCR3 inhibitors, preclinical and clinical evaluations, and assessment of their immunomodulatory effects within the tumor microenvironment. These findings contribute to the development of novel, flavonoid-derived therapeutic strategies in cancer treatment.

Environmental Public Health Tracking in England- support for Health Impact Assessments

Abstract Environmental epidemiology is a key function for the public health service with regards to investigating the public health effects of environmental hazards, monitoring the public health efforts to control the environmental risks, and providing the evidence that informs decisions making and preparedness. At the United Kingdom Health Security Agency (UKHSA), the Environmental Public Health Tracking (EPHT) Programme, initiated in 2010, has developed a number of data streams to help link environment and health data, to support Health Impact Assessment (HIA). The main aims of the EPHT programme in England are to: 1. Identify populations at risk from exposure to significant environmental and chemical hazards 2. Investigate relationships between hazard and disease 3. Inform public health policy making 4. Optimise intervention and prevention strategies 5. Generate hypotheses for further research. Such EPHT functions are based on three key components: a) by building a national EPHT program that integrates surveillance of environmental hazards, exposures and related health outcomes, to allow data linkage and assessment of environmental and health information; b) strengthening the epidemiology science, by conducting research and training of the workforce and c) developing strategies for response to immediate risks, incidents and preparing for future risks. Examples to support HIA include a) developing an air pollution exposure surveillance work programme, that has designed a pilot population vulnerability indicator; b) developing indicators for climate change impacts for public health, c) reporting regularly on the health impacts of public fluoridation water supply schemes (as mandated by Government) and d) exploring risk factors associated with elevated blood lead concentration in children, through laboratory reporting to surveillance systems. The talk will highlight some examples of practice and outline how the EPHT programme in England has supported HIA practices.

Economic evaluation of fractional flow reserve-guided versus intravascular ultrasound-guided percutaneous coronary intervention

Abstract Background The randomized, controlled FLAVOUR trial demonstrated that the clinical outcomes of the fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) strategy were non-inferior to the intracoronary ultrasound (IVUS)-guided PCI strategy. Purpose This study aimed to compare the difference in economic implications and health-related quality of life between the two strategies. Methods A total of 890 patients with intermediate stenosis in 9 sites in China from the FLAVOUR trial were included. Direct medical costs were calculated using a combination of resource-based and event-based methods. Health utility was defined as quality-adjusted life years and assessed based on the 19-item Seattle Angina Questionnaire. The primary analysis was a cost-utility analysis. Probabilistic sensitivity, one-way sensitivity, and subgroup analyses were performed. Results At two years, the average total cost per patient was Chinese yuan (CNY) 36,287±19,531 in the IVUS-guided group and CNY 29,237±19,239 in the FFR-guided group (ΔIVUS-FFR=CNY 7,050, p<0.001). The difference was driven primarily by the cost of initial admission (ΔIVUS-FFR=CNY 6,284, p<0.001). Quality-adjusted life years gained showed no significant differences between the two groups (FFR vs. IVUS: 1.639±0.086 years vs. 1.638±0.128 years, p=0.872). The probabilistic sensitivity and one-way sensitivity analyses revealed robust results. The subgroup analysis found that the cost reductions attributed to FFR guidance decreased in several subgroups, including patients with diabetes and those with high anatomical complexity. Conclusions In patients with intermediate stenosis, FFR-guided PCI is associated with significant cost savings compared with IVUS-guided PCI at two years and shows no differences in health-related quality of life outcomes.Central Illustration

Exploring the associations of tobacco smoking and serum cotinine levels with selected inflammatory markers in adults with HIV in South Africa

This study examined the associations between tobacco smoking and serum cotinine levels, an objective biochemical measure of tobacco smoke exposure, with markers of inflammation, i.e., interferon-gamma (IFN-γ), interleukin 10 (IL-10), interleukin 2 (IL-2) and tumour necrosis factor-alpha (TNF-α) in people living with HIV (PLWH).These specific markers were selected because of their hypothesised associations with smoking, PLWH and their outcomes. In a random sample of ≥ 18-year-old PLWH receiving care at 17 public healthcare facilities across the Western Cape Province in South Africa, data collection included self-reported smoking history, and serum levels of cotinine and selected inflammatory markers. The inflammatory marker data were log transformed because of the skewedness of their distribution. Linear regression models (1) adjusted for age and gender, and (2) fully adjusted for age, gender, current alcohol use, body mass index and CD4 counts were used to examine the associations between smoking tobacco or serum cotinine and inflammatory markers. Level of significance was p < 0.05. Among 749 PLWH who were mainly women (79%), the mean age was 38.5 (8.9) years and similar when stratified by smoking status. Serum cotinine levels exhibited a striking discrepancy, with a median of 154 ng/mL among current smokers, in stark contrast to the consistent median values of 10 ng/mL observed among past and never smokers. In regression models adjusted for age and gender, current smoking and frequent smoking were associated with lower IL-2 but higher TNF-α. Log-cotinine exhibited associations with IFN-γ, IL-10, and TNF-α, while cotinine levels ≥ 10 ng/mL compared to < 10 ng/mL were associated with higher IFN-γ and TNF-α. In fully adjusted models, log-cotinine and cotinine levels ≥ 10 ng/mL displayed significant associations with higher IFN-γ and lower IL-2. This study underscores the importance of investigating the interplay between smoking tobacco or serum cotinine levels with pro-inflammatory cytokines in PLWH. It signals the need for comprehensive research to unravel the potential synergistic impacts of smoking tobacco and HIV infection on chronic inflammation and immune dysregulation, shedding light on critical avenues for intervention and management strategies.

Why greenhouse agricultural workers do not use pesticide protection methods? A case study

Abstract Background Exposure to pesticides in individuals working in greenhouse agriculture is an important public health problem that threatens their health more than individuals working in other agricultural jobs for the same period of time, causing an increase in mortality and morbidity rates. Applying protection methods plays an important role in reducing/preventing exposure-related health risks. It is aimed to explore the reasons why greenhouse agricultural workers do not use pesticide protection methods. Methods This case study was adopted the descriptive qualitative approach between February-March 2024. Individual in-depth face-to-face interviews were conducted with semi-structured interviews, resulting in 20 participants. The inclusion criteria for participants include being a greenhouse agricultural worker (at least 1 year), being 18 years of age or older, using pesticides, not using any personal protective equipment, and not engaging in protective behavior. Braun and Clark’s (2021) reflexive thematic analysis methodology was used to analyze the data. Results In this study generated three main themes and fourteen subthemes. The main themes identified were a) personal attitudes/ characteristics b) negative features of the physical environment, c) negative features of personal protective equipment. Conclusions The reasons why greenhouse agricultural workers do not use pesticide protection methods are individual attitudes/characteristics such as laziness and not to care about, negative characteristics of the environment such as temperature, humidity and wetness, and negative characteristics of personal protective equipment such as being heavy and inflexibility. Health institutions and health professionals serving in regions where agricultural workers should develop interventional studies, intervention programs and strategies to protect and improve the health of these individuals. Key messages • Greenhouse agriculture workers do not use any of the pesticide protection methods due to individual attitudes/characteristics, negative characteristics of environment and personal protective equipment. • Health professionals can ensure that greenhouse agricultural workers use pesticide protection methods by increasing their awareness of health risks and planning interventional studies.

Making Conscientious Decisions: Engaging in Venous Leg Ulcer Self-Management Following Nurse-Led Patient Education.

Venous leg ulcers (VLUs) provoke multiple symptoms and impact individuals and society as a whole. Their treatment and prevention strategies require individual's involvement in self-management strategies. Insufficient knowledge with regard to prevention, management, and treatment has been identified as a critical factor related to VLUs and their recurrence. Therapeutic patient education (TPE) proposed as part of a management strategy for this population provides unclear benefits regarding wounds healing or prevention of recurrence. The aim of the study was to develop a theory explaining how individuals with a VLU experience an individualized nurse-led TPE program regarding self-management strategies. The constructivist approach of Charmaz to the grounded theory method was used to develop the theory. A total of 26 individuals contributed to the co-construction of the theory through face-to-face or telephone semi-structured interviews. Data analysis and data collection occurs simultaneously with a comparative process to reveal the conceptual categories, apply theoretical sampling, and define theoretical saturation. The theory of "Conscientiously Engaging in Self-Management" was co-constructed with the participants encapsulating four categories: "Being influenced by my own story," "Being personally informed," "Making conscientious decisions to engage in self-adapted management strategies," and "Integrating a conscientious way of living." This theory highlights individuals' voices and stories toward their journey of VLU self-management taking contextual factors into consideration. This new theory offers new knowledge about implementation of self-management strategies for individuals living with a VLU and will inform clinical practice and contribute to the development of targeted interventions.

Differences in risk profiles and clinical outcomes according to age in patients with high-risk myocardial infarction: insights from the PARADISE-MI trial

Abstract Introduction Temporal declines in rates of rehospitalization and death after acute myocardial infarction (MI) have not been uniform across age groups. A better understanding of how risk profiles and clinical outcomes differ after MI by age may allow for targeted treatment and prevention strategies. Aims To investigate risk profiles and clinical outcomes following high-risk MI according to age in the Prospective ARNI vs ACE inhibitor trial to DetermIne Superiority in reducing heart failure Events after Myocardial Infarction (PARADISE-MI). Methods Adults without prior heart failure (HF) were randomized to sacubitril/valsartan versus ramipril within 0.5 to 7 days of a MI complicated by transient pulmonary congestion and/or left ventricular systolic dysfunction and additional risk-augmenting factors. Associations between age and clinical outcomes were analyzed using Cox proportional hazards regression models, which were additionally adjusted for baseline demographic and clinical covariates (Figure). Results The mean age of the 5,661 PARADISE-MI participants was 64 ± 11 years. Patients aged ≥75 years (n=1051) were more likely women, had more hypertension and atrial fibrillation and lower estimated glomerular filtration rate, were less likely to present with ST-segment elevation MI and regardless of type of MI were less likely to receive primary reperfusion and guideline-based medical therapy (Table). Age was significantly associated with all-cause death (HR 1.54 per 10-year increase; 95% CI, 1.41-1.68) and was more strongly associated with non-CV death (HR 2.09; 95% CI, 1.70-2.56) than with CV death (HR 1.43; 95% CI, 1.29-1.57). Age was also associated with incident HF (HR 1.37; 95% CI, 1.25-1.49) (Figure). Multivariable adjustment attenuated the risk relationship of age with recurrent fatal or non-fatal MI (HR 1.08; 95% CI, 0.96-1.21) and the coronary composite outcome (HR 1.01; 95% CI, 0.93-1.09). The relative treatment effect of sacubitril/valsartan versus ramipril on the primary composite outcome of CV death or incident HF was not significantly modified by age (p-interaction = 0.19). Conclusions Following high-risk MI, age was most strongly associated with subsequent non-CV death followed by CV death and incident HF, but was not independently associated with recurrent coronary events. The heightened risk of CV death and HF with advancing age was not explained by differences in clinical characteristics. Older patients may require closer surveillance and more aggressive treatment after MI to mitigate the elevated risk of CV death and HF.

Failure of primary prophylaxis: statin use, risk profile, and outcomes in contemporary patients treated with PCI for first atherosclerotic event

Abstract Background Atherosclerosis and coronary artery disease (CAD) are potentially preventable through lifestyle modifications and the use of medical cholesterol-lowering drugs in individuals at risk. However, guidelines for optimal use of statins are debated, and not enough is known about the real-world barriers to effective CAD-prevention. Understanding the mechanisms of prophylactic treatment failure in patients who undergo PCI for their first atherosclerotic event could help improve primary prevention strategies. Purpose To 1) examine the relative contribution of failure mechanisms of medical prophylaxis in patients undergoing PCI for their first atherosclerotic event, 2) examine how clinical characteristics differ between patients with different failure mechanisms, and 3) examine whether long-term outcomes after PCI differ depending on the mechanism of prophylactic failure. Methods A retrospective study was conducted to study electronic healthcare records for all patients ≥18 years treated with PCI at Gentofte Hospital, Denmark in 2019. Data was extracted from electronic health care records. Patients with first atherosclerotic event were divided into cardiovascular risk groups based on the ESC/EAS guidelines and further into four different prophylactic failure mechanism groups based on cardiovascular risk, statin indication, statin use and whether the risk-based LDL-C treatment goals were reached. Results 507 patients were treated with PCI for their first atherosclerotic event. 54% were categorized as low-moderate cardiovascular risk. 41% were not on statin and did not have class I indication for statin treatment (strategy failure). 26% were not on statin treatment despite class I indication for statin treatment (implementation failure). 18% were on statin treatment but had not reached their LDL-C target (efficiency failure), and 16% were on statin treatment, and had reached the LDL-C target (efficacy failure). Patients with strategy failure, were more likely to be younger, mostly males, and often had a smoking history. Patients with implementation failure, were typically elderly, with relatively few comorbidities. The frequency of death, myocardial infarction, stroke, or repeat revascularization over 4 years was 15.3%, with no statistically difference between the groups (p =0.3). Conclusion In this cohort study, patients treated with PCI for first atherosclerotic event were often classified as low or intermediate risk, and a majority had not been on statin treatment before. Improved primary prevention should focus on at-risk groups that are either not included in current recommendation for statin treatment, especially young smokers, or patients not receiving treatment despite recommendations, especially older patients with few medical contacts.Cardiovascular risk &amp; failure mechanismKaplan-Meier MACE

KardioNet Digital - a structured care model involving digital tools for intersectoral communication and a patient-focused strategy for treatment of heart failure

Abstract Introduction Inefficiencies and discontinuities in care at the interfaces within Germany's healthcare system, especially between acute and outpatient care, present significant challenges in managing patients with heart failure (HF). The management complexity of HF has increased with the advent of new digital tools, though patient acceptance of these tools remains contentious. The prevention of loss of diagnostic and therapeutic information for this complex disease is crucial for cross-sectoral communication (hospital - office-based cardiologist - general practitioner) and quality of care. Purpose Our goal was to examine the impact of digital app-supported coordination of HF management across different healthcare providers from hospital discharge to the ambulatory sector and to assess patients' acceptance of a structured care program. A patient-focused digital strategy, supported by a Heart Failure Nurse (HFN), aimed to facilitate structured follow-up and patient empowerment, focusing on patient-reported outcomes and experiences (refer to Table 1). Results Out of 401 patients screened during their hospital stay for HF, only 57 (14.9% male, 12.6% female) participated in the KardioNet Digital (KND) program. NYHA classifications were I (3.5%), II (49.1%), III (40.4%), and IV (7.1%); Diagnoses included CMP (26, 45.6%), CAD (19, 33.3%), valvular HF (8, 14.0%), and others (4, 7.0%). The mean age was 55.03 years, with a notable difference in participation based on age (≥70 years: 9.5% male, 33.3% female; &amp;lt;70 years: 90.5% male, 66.7% female). Age was a significant determinant of program participation. Patients who regularly used the app benefited from several features: A total of 35 alerts (17 patients) were triggered for reasons such as bodyweight increase (2kg or more) and device-induced alerts (i.e. false shock delivery, 3x slow-VT, Syncope), leading the HFN to contact the patients. This early intervention prevented rehospitalization due to decompensation of heart failure in 11 patients (64.7%) and addressed device-related alarms for organizing an emergency hospital visit by HFN. Despite substantial incentives, such as support from an HFN and expedited appointments with specialists for follow-up therapy, refusal rates were high (refer to Table 2). Conclusion A structured, digitally supported cross-sectoral care model for heart failure patients can potentially improve care coordination and outcomes. However, the success of such programs critically depends on patient willingness and the seamless integration into existing healthcare structures. Despite valuable incentives, we observed low acceptance of the program. Even among motivated participants (14.1%), there is a significant need for substantial support and education on digital literacy for the widespread implementation of digital tools in real-world settings for the treatment of heart failure.Workflow of structured digital supportReasons for Declining Participation

Forecasting Psychological Distress Across Waves Of The COVID-19 Pandemic: A Multi-country Longitudinal Study

Abstract The current study used a longitudinal multi-country cohort survey (N = 8013 at baseline; age (M) = 40.3, SD = 15; female 76%) to investigate whether psychological distress assessed at five waves (May-June 2020; September-October 2020; December 2020-January 2021; March-April 2021 and March-May 2022) during the COVID-19 outbreak can be forecasted by a variety of socio-demographic and psychological- and COVID-related factors assessed at baseline. Psychological distress was defined by elevated depression and/or anxiety scores (PHQ-9 and GAD-7 &amp;gt; = 10). Predictors included demographic characteristics (e.g., gender, age, education), infections with COVID-19, loss of income, substance abuse, domestic violence, contamination fear, basic value orientations, social support and coping strategies. A Random Forest (RF) prediction model within a machine learning context was used to estimate the association between the independent variables and the presence of psychological distress among respondents completing all waves (N = 1052). Preliminary RF results showed that psychological distress at multiple waves, both during the initial phases (2020) as well as the more protracted phases (2021 and 2022), was adequately forecasted by scores on a number of basic value orientations (e.g., lower tradition and conformity, higher security and predictability), by demographic characteristics (e.g., younger age), by the fear of being contaminated, and by lower levels of social support and higher levels of loneliness. It is concluded that during a pandemic, certain personal values may elicit more vulnerability for psychological distress than others. Effective psychological intervention strategies should encompass personal traits and values and factors such as low social support levels and feelings of loneliness to mitigate distress. These insights can help in accurately pinpointing high-risk groups for heightened distress in future public health crises.

Intervention Strategies to Reduce Maternal Mortality in the Context of the Sustainable Development Goals: A Scoping Review

According to the United Nations Population Fund, approximately every two minutes, a woman dies, totalling approximately 800 deaths per day for reasons related to a maternal causes. Therefore, within the Sustainable Development Goals of the 2030 Agenda, the goal is to reduce the global maternal mortality rate to less than 70 deaths per 100,000 live births by 2030. We aim to analyse strategies to reduce maternal mortality in the context of the Sustainable Development Goals, identify barriers that hinder their implementation, and analyse the impact of the COVID-19 pandemic on their achievement. We performed a scoping review of the following databases and distributors of specialised information in the health area: PubMed, Medes, Lilacs, Cuiden, Cinahl, Scopus, SciELO, and websites of the United Nations (UN), United Nations Population Fund (UNFPA), and Cooperanda. A total of 24 articles were reviewed. The results obtainded determined that reviewed studies agree that despite efforts to reduce maternal mortality, significant social and structural barriers still exist in developing countries that slow the implementation of strategies to protect maternal health, especially in the most at-risk populations, and the improvement of the health system. The main strategy consists of increasing the number of deliveries attended by qualified personnel, which is the greatest indicator of progress in reducing maternal mortality. To conclude, Economic, social, and political barriers remain in developing countries in the context of the Sustainable Development Goals. The intervention that has shown the most success is the attendance of deliveries by qualified personnel. It is essential to prioritise maternal care, triangular cooperation, and effective connection between the different Sustainable Development Goals.

Factors Associated With Health-Promoting Behaviors Among South Korean Adults: A Cross-Sectional Study.

To examine the association between positive psychological capital, social support, illness attitudes toward COVID-19, and health-promoting behaviors in Korean adults. An online cross-sectional study. The participants were 820 South Korean adults aged 19-64, recruited through quota sampling. The sample was census-matched in terms of age and gender based on the Korean Population Census. The participants completed measures assessing psychological capital, social support, illness attitude toward COVID-19, and health-promoting behaviors. The t-test, one-way analysis of variance, Pearson's correlation, and multiple stepwise regression analysis were used to analyze the data. Participants who were religious, perceived themselves as physically healthy, had negative illness attitudes, had high positive psychological capital, and received high social support were more likely to engage in health-promoting behaviors. These variables explained 44.5% of the participants' health-promoting behaviors. This study is the first to examine illness attitudes toward COVID-19 and health-promoting behaviors among South Korean adults during the COVID-19 pandemic. The results can pave the way for effective public health intervention strategies that consider religiosity, physical health status, illness attitude, and social support, to promote healthy living during future public health crises.
