Aims: The effect of sodium–glucose cotransporter 2 inhibitors (SGLT2is) in addition to optimal medical therapy (OMT) on right ventricular (RV) systolic function in patients with heart failure with reduced ejection fraction (HFrEF) is not well established. This study aimed to assess the impact of SGLT2is on RV function using advanced echocardiographic parameters in patients with HFrEF and type 2 diabetes (T2D). Methods: The real-world prospective, observational GLISCAR study enrolled 31 consecutive patients with T2D and HFrEF. All participants underwent clinical evaluation, laboratory testing, and comprehensive echocardiography at baseline and after 12 months of treatment with an SGLT2i. Results: After 12 months, statistically significant improvements in RV function were observed. Tricuspid annular plane systolic excursion (TAPSE) increased from 18.00 mm (SD ± 4.23; 95% confidence interval (CI): 16.51–19.49 mm) to 19.40 mm (SD ± 4.13; 95% CI: 17.95–20.85 mm) (p = 0.0346), and pulmonary artery systolic pressure (PASP) decreased from 35.23 mmHg (SD ± 14.61; 95% CI: 30.09–40.37 mm) to 30.89 mmHg (SD ± 7.77; 95% CI: 28.15–33.63 mm) (p < 0.001). These changes may suggest favorable RV remodeling and improved right ventricular–arterial coupling (RVAC). Conclusions: SGLT2i therapy was associated with improved RV function and RVAC in patients with HFrEF and T2D. While these findings are preliminary and drawn from a small, observational cohort, they support a potential role for SGLT2is in right heart remodeling. Further randomized, controlled studies are needed to confirm these effects and clarify their clinical implications. Full article

Background: The optimal revascularization strategy for patients with left main coronary artery (LMCA) disease has been repeatedly addressed in randomized controlled trials (RCTs), although outcomes from real-life clinical studies are still poorly investigated. Objectives: This retrospective study aimed to assess the complete 5-year outcomes for individuals with multivessel coronary artery disease (MVD) involving LMCA disease treated with coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) as recommended by a local HT. Methods: From 2016 to 2019, 176 Heart Team (HT) meetings were held. Primary and secondary endpoints of 267 patients with MVD involving LMCA disease qualified either for CABG or PCI (109 and 158 patients, respectively) with subsequent optimal medical therapy (OMT) were assessed. The primary endpoint of the study was as an overall mortality, while secondary endpoints contained major adverse cardiac and cerebrovascular events (MACCE)—specifically, stroke, myocardial infarction (MI), repeat revascularization (RR), and the individual components of MACCE. Results: At 5 years, we found no significant difference in overall mortality between the both cohorts (22.9%-CABG vs. 24.7%-PCI, p = 0.74). The rate of MI was higher in patients treated percutaneously (7.3% vs. 15.8% for PCI, p = 0.04), while the incidence of stroke was higher in patients who underwent CABG (3.8% vs. 11.0% for CABG, p = 0.02). A MACCE occurrence was higher in PCI cohort (77.2% vs. 55.0%, p < 0.001), mainly driven by higher rates of RR was higher in patients treated percutaneously (32.9% vs. 13.8%, p < 0.001). Conclusions: For patients with LMCA disease, neither CABG nor PCI following HT decisions showed overwhelming superiority in real-life clinical practice: occurrence of all-cause death was similar, rates of MACCE, MI, and repeat revascularization advocated CABG, while incidence of strokes favored PCI.

Background/Objectives: Heart failure (HF) with reduced ejection fraction (EF) has, in more than 50% of cases, an ischemic etiology and continues to be associated with increased mortality and morbidity despite all the progress registered in the field of medical therapy and interventional revascularization. Myocardial revascularization is extensively used in clinical practice based on the traditional concept that it can improve myocardial function and outcome in ischemic HF. This review is aimed at presenting current knowledge regarding revascularization in patients with chronic ischemic HF and reduced EF. Methods: The impact of revascularization on symptomatology, left ventricle reverse remodeling, major adverse cardiac events (MACEs), and the role of complete revascularization and of percutaneous interventional revascularization in chronic total occlusion (PCI-CTO) were analyzed. The best therapeutic strategies, revascularization and/or optimal medical therapy (OMT), are debated in different categories of patients, in order to identify who will benefit more from revascularization strategies. Results: Based on the long-term results of the STICH trial incorporated in the guidelines with a class I-b recommendation, coronary artery bypass graft (CABG) remains the main modality of revascularization for prognostic improvement in ischemic HF with multivessel disease. But real-life patients are usually old with multiple comorbidities and high surgical risk. In this category, the Heart Team opinion is required to evaluate the probability of complete revascularization and to choose between percutaneous coronary intervention (PCI) and CABG according to clinical status and coronary anatomy. Conclusions: However, until further studies are available, the results of the REVIVED-BCIS2 trial encourage OMT over PCI in patients with ischemic cardiomyopathy. The available randomized controlled trials (RCTs) showed improved angina and quality of life in PCI-CTO versus OMT, but the effect on MACEs was not demonstrated. Full article

Background: Arterial hypertension (HTN) is the leading modifiable cardiovascular risk factor for overall mortality worldwide. In Austria, 1.6 million individuals above the age of 15, representing 20% of the total population and 70% of adults aged 65 and older, suffer from HTN. Despite numerous antihypertensive treatment options on the European market, only 38.8% of patients on optimal medical treatment (OMT) reach their treatment goal. Primary prevention remains a challenge, particularly for HTN and the consequential risk of cardiovascular diseases (CVDs). Thus, there is an urgent need for Disease Management Programs (DMPs). We sought to study a possible trial to diagnose hypertension in a non-medical setting at a very early stage of the disease and raise awareness for hypertension in affected people to avoid future complications of unrecognized and untreated HTN. For a non-medical setting, hairdressers fulfil many criteria for an optimal blood pressure (BP) measurement. Methods: This is a pilot study. A total of 193 individuals were included at a Viennese hairdresser. Metric data were described either using mean ± SD given normal distribution or median otherwise. Categorical data were described using absolute frequencies and percentages. For comparison, either independent t-tests or Mann–Whitney U tests or chi² tests were assessed. The staff received expert training on how to measure blood pressure in a guideline-compliant way. All members signed the written and informed consent and received a questionnaire about their demographic data and cardiovascular risk factors. Results: Of the 193 participants in this study, 56.5% (109/193) were female and 43.5% (84/193) were male. The mean age was 54 ± 15.1 years. In the automatically measured office blood pressure (AOBP) measurement, the mean systolic BP was 137.1 ± 17.8 and the mean diastolic BP was 91.6 ± 11.2. Of all participants, 65.8% (127/193) were hypertensive, whereof 74.8% (95/127) had no treatment at all. Among 127 individuals evaluated, 63% (80/127) were unaware of their elevated blood pressure levels, while 28% (44/127) had a prior diagnosis of HTN. The control rate of the individuals with previously diagnosed HTN was very low, with only 18.5% [10.4; 30.9] reaching normotensive values in the current measurement. There was no difference in BP values of patients with previously diagnosed HTN and patients who were unaware of their disease. Antihypertensive treatment was being received by 20.2% (39/193), while 62.2% had not taken their prescribed blood pressure medication on the day of recruitment. Conclusions: This is the first Austrian study to show that screening for HTN in an unconventional non-medical setting is effective to diagnose HTN and raise awareness. Based on the even-higher-than-expected prevalence of HTN, we plan to conduct a cohort study in Vienna, inviting all hairdressers in socially deprived districts to act as gate openers for hypertensive subjects to raise awareness and to contact a regional GP for provision of medical care. An implementation of such a cost-effective and feasible disease management program in Austria might therefore reduce the burden of preventable cardiovascular events associated with HTN. Full article

The aim of the present observational study was to evaluate the early effect of free-form essential amino acid (EAA) supplementation on cardiac and muscular performance in elderly patients with chronic heart failure (HF) with reduced ejection fraction (HFrEF) and sarcopenia, as add-on to the optimized medical therapy (OMT) for HF. The present study included 60 elderly Caucasian patients suffering from HFrEF and sarcopenia. At the baseline and at follow-up, all patients underwent complete physical examination with the determination of the main anthropometric and hemodynamic parameters. After 6 months of supplementation with EAAs, we observed significant improvements in the parameters of sarcopenia. In addition, there was a significant improvement in glycol-metabolic parameters, and in inflammatory index as high sensitivity C-reactive protein (hs-CRP). In accordance with these results, significant decreases were observed in circulating levels of oxidative stress biomarkers Nox-2 (p < 0.001) and 8-Isoprostane (p < 0.001), and platelet aggregation biomarkers such as sP-Selectin (p < 0.001) and Gp-VI (p < 0.001). Of particular interest, after 6 months’ follow-up, there was a significant improvement in LVEF and global longitudinal strain (GLS). In conclusion, this study demonstrates that targeted nutritional intervention with EEAAs represents a viable therapeutic strategy for addressing the complex interplay between cardiac dysfunction and skeletal muscle wasting in elderly HF patients.

Intermittent claudication is the most common manifestation of peripheral arterial disease as well as a lifestyle-limiting disease with a favorable prognosis. Despite societal guideline recommendations, most claudicants do not trial optimal medical therapy (OMT) and supervised exercise therapy (SET) or receive a quality-of-life (QoL) assessment prior to intervention. In this review, we discuss the components of OMT and SET and the trials establishing their clear benefits in claudicants. We assess adherence rates to OMT/SET and qualitative and quantitative studies attempting to understand the barriers to adoption. We also review how patient-reported outcome metrics were developed to assess QoL in claudicants and reasons for their underutilization in daily clinical practice. Last, we describe novel initiatives seeking to improve adherence to OMT, SET, and QoL assessment. Full article

The European chickpea market raises concerns about health risks for consumers due to contamination by mycotoxins. Contamination levels can vary depending on the farming system, and rapid and reliable screening tools are desirable. In this study, marketed chickpea seed samples from organic and non-organic farming systems were analyzed for fungal and mycotoxin contamination. Aspergillus and Penicillium were the most frequently identified mycotoxigenic genera. Significant differences in fungal detection were observed among the three isolation methods used, whose combined application is proposed to enhance detection efficiency. The number of Aspergillus and Penicillium colonies was significantly higher in the organic samples. Molecular analysis identified different species within each genus, including several not previously reported in chickpea, as well as potentially aflatoxigenic species such as A. flavus/oryzae and A. parasiticus. LC-MS/MS analysis revealed aflatoxin production only by A. parasiticus, which was present in low amounts. However, the presence of potentially aflatoxigenic Aspergillus species suggests that chickpeas should be monitored to detect their safety and subsequently protect consumer health. A qPCR protocol targeting the omt-1 gene, involved in aflatoxin biosynthesis, proved to be a promising rapid tool for detecting potentially aflatoxigenic Aspergillus species. Full article

Chronic total occlusions (CTOs), defined as complete coronary artery blockages persisting for over three months, are frequently encountered in up to 25% of coronary angiograms. Although percutaneous coronary intervention (PCI) for CTO remains technically challenging, advancements in guidewires, microcatheters, re-entry devices, and intravascular imaging, along with the expertise of specialized operators, have significantly improved procedural success rates, now exceeding 90% in expert centers. While recent evidence, such as the SYNTAX II study, emphasizes the importance of complete revascularization, over half of CTO cases continue to be managed conservatively with optimal medical therapy (OMT), partly due to the limited high-quality randomized evidence supporting revascularization. Observational studies have demonstrated that successful CTO-PCI is associated with improved angina relief, quality of life, left ventricular function, and possibly long-term survival. Extended observational follow-up, such as the Korean and Canadian registries, suggests long-term reductions in cardiac and all-cause mortality with CTO revascularization. However, randomized controlled trials (RCTs) have primarily shown symptomatic benefit, with no consistent reduction in major adverse cardiac events (MACE) or mortality, likely due to limited sample sizes, short follow-up, and treatment crossovers. Various strategies, including the hybrid algorithm, guide CTO interventions by balancing antegrade and retrograde techniques based on lesion complexity. Imaging modalities such as coronary CT angiography and intravascular ultrasound play a pivotal role in planning and optimizing these procedures. Future innovations, such as real-time fusion imaging of CCTA with coronary angiography, may enhance lesion visualization and guidewire navigation. While current guidelines recommend CTO-PCI in selected symptomatic patients with demonstrable ischemia or viable myocardium, the decision should be individualized, incorporating anatomical feasibility, comorbidities, patient preferences, and input from a multidisciplinary Heart Team. Looking ahead, adequately powered RCTs with extended follow-up are essential to determine the long-term clinical impact of CTO-PCI on hard outcomes such as mortality and myocardial infarction.

Orofacial myofunctional therapy (OMT) for obstructive sleep apnea (OSA) is a promising, new treatment. We aimed to study patients’ experiences and adherence to OMT. Twelve patients with OSA were included in the study, and they engaged in OMT exercises three times daily for 12 weeks. Participants tracked their sleep and OMT exercise activities in an electronic diary. Exercise techniques were guided by a certified therapist. Patients’ experiences with OMT were assessed through semi-structured individual interviews conducted after a 12-week intervention, and the transcripts were analyzed using thematic analysis. The findings revealed an overarching theme that captured both facilitators of and barriers to OMT, organized into three subthemes: (1) motivation, (2) perceived support, and (3) perceived effects. Motivation was driven by a desire to improve general health and avoid continuous positive airway pressure treatment, and was supported by a sense of mastery and perceived effectiveness. Key facilitators included a trusting patient–therapist relationship, as well as developing routines and a sense of control. Barriers involved managing the comprehensive treatment protocol, insecurities around exercise execution and the potential impact of OMT, sickness burden, and previous negative healthcare experiences. These themes were supported by quantitative findings, which demonstrated high treatment adherence, while sleep data indicated modest individual improvements in subjective sleep quality and efficiency. By recognizing facilitators and barriers and addressing the individual differences among OSA patients, healthcare providers can better tailor their approach to meet diverse patient needs. This personalized approach, supported by emerging sleep improvements, may enhance patient engagement and improve adherence to OMT. Full article

Background and aims: Opioid maintenance therapy (OMT) is the first-line treatment for opioid use disorder (OUD), reducing opioid use and mortality while improving physical and mental health. However, concomitant substance use remains common, with cannabis being the most frequently used substance. This study assessed the prevalence and clinical correlates of cannabis use in OMT patients, as well as individual motivations. Methods: In this cross-sectional, single-center study, 128 OUD patients (96 male, 32 female) receiving OMT were assessed using standardized questionnaires: the Marijuana Smoking History Questionnaire (MSHQ), Cannabis Problems Questionnaire (CPQ) and the Severity of Dependence Scale (SDS). Cannabis users and non-users were compared regarding type (methadone vs. buprenorphine) and dosage of maintenance medication. Results: Cannabis use was reported by 41% of patients, 73% met criteria for cannabis dependence, 30% of the full sample. Of the patients, 85% reported cannabis-related legal issues. Common reasons for use included recreational motives (mood change, enhancement) and reduction in cravings for other substances. Cannabis dependence was significantly more common in patients receiving buprenorphine than methadone. Higher methadone doses were also associated with increased cannabis use. These results suggest a clinically relevant pattern. Conclusions: Cannabis use is highly prevalent and appears to be influenced by type and dosage of substitution medication. These findings highlight a complex interaction between opioid treatment and cannabis use, possibly involving behavioral coping or regulatory processes. Further longitudinal and placebo-controlled trials are needed to investigate the clinical and pharmacological interactions between cannabis and OMT, including effects on craving, withdrawal, and overall treatment outcomes.

Background: Even with advanced management involving pharmacologic and ventilatory strategies, respiratory dysfunction increases morbidity and reduces the quality of life. This narrative review examines how craniofacial and cervical manipulative interventions—including nasomaxillary skeletal expansion, breathing re-education, and structural techniques—may holistically optimize airway function by enhancing neurological and lymphatic dynamics, modulating vagal tone, reducing pharyngeal collapsibility, and supporting immune regulation across diverse clinical settings. Objectives: To explore manual techniques that influence respiratory and autonomic function and to evaluate their reported clinical efficacy and supporting evidence, particularly in the context of airway disorders such as asthma and pneumonia. Methods: A narrative review of the literature from PubMed and Google Scholar was conducted using search terms related to airway function and osteopathic manipulative techniques (OMTs). The inclusion criteria spanned 2010–2025 English-language peer-reviewed full-text articles on airway function, OMT, and emergency airway maneuvers. Clinical trials, observational studies, and reviews were included; non-peer-reviewed content and animal studies (unless mechanistically relevant) were excluded. Chapman’s reflexes related to respiratory function were incorporated to highlight somatic–visceral correlations. Key Findings: The techniques reviewed included frontal lift, vomer manipulation, maxillary and zygomatic balancing, and cervical adjustments. Thoracic OMT methods, such as diaphragm doming and lymphatic pump techniques, were also addressed. Emergency techniques, such as the BURP and Larson maneuvers, prone positioning, and high-frequency chest wall oscillation, were presented as comparative strategies to OMTs for acute airway management. Conclusions: Craniofacial and cervical manipulations can be a promising adjunct for enhancing airway function. However, the current literature displays heterogeneity and lack of large-scale randomized trials, which emphasize the necessity for standardized research and the establishment of clinical guidelines with the collected evidence.

The development of antimicrobial and antioxidant packaging materials is critical for improving food safety and extending shelf life. This study aimed to design and characterize low-density polyethylene (LDPE) and poly(ethylene-co-vinyl acetate) (EVA) films incorporating organically modified montmorillonite (OMt) nanocarriers loaded with carvacrol (C) and thymol (T) essential oil components. The incorporation of carvacrol and thymol into OMt was conducted through an evaporation/adsorption method without the use of organic solvents. In the next step, LDPE, EVA and OMtC or OMtT were melt-compounded in order to obtain films. Characterization of the bioactive nanocarriers and films was performed through X-ray diffraction (XRD), tensile testing, oxygen permeability measurements (OTR) and antioxidant assays. Films LDPE/EVA/OMtC and LDPE/EVA/OMtT showed improved mechanical strength and antioxidant activity, with IC₅₀ values between 0.32 and 0.52 mg/mL. Film with component weight ratio LDPE/EVA/OMtC equal to 80/10/10 also demonstrated enhanced barrier properties and significantly inhibited fungal growth on baguette bread for up to 60 days. These findings highlight the potential of these bioactive films to improve the microbial safety and shelf life of bakery products. Full article

Background/Objectives: Pediatric obstructive sleep apnea (OSA) is a prevalent medical condition, affecting 1–5% of non-syndromic children and 30–90% of children with Down syndrome. Given the severity of the condition and the associated health risks, early and effective treatment is crucial. However, current treatment modalities are often invasive or suffer from poor patient adherence. Additionally, adenotonsillectomy, the first-line treatment in pediatric OSA, seems not to be effective in every child, leaving children with residual OSA postoperatively. These challenges are particularly pronounced in high-risk populations, such as children with Down syndrome, highlighting the need for alternative therapeutic strategies. Therefore, a protocol is presented to evaluate the effectiveness of orofacial myofunctional therapy (OMT) as a treatment for OSA in two pediatric populations: (1) Non-syndromic children aged 4–18 years: 10 weeks of OMT. (2) Children with Down syndrome aged 4–18 years: 20 weeks of OMT. Effects of the OMT program will be evaluated on: sleep parameters (e.g., obstructive Apnea–Hyponea Index (oAHI), snoring frequency); orofacial functions (e.g., breathing pattern, tongue position at rest); quality of life outcomes. Methods: A pretest–posttest design will be used to evaluate the effectiveness of OMT in both children with and without Down syndrome and OSA. Both objective measures and patient-reported outcomes are being collected. Results: OMT is expected to improve orofacial functions, reduce OSA severity and symptoms, and enhance quality of life in both non-syndromic and syndromic children. Conclusions: This multidisciplinary research protocol, involving collaboration between ENT specialists and speech-language pathologists, aims to provide a comprehensive understanding of the potential benefits of OMT in treating OSA.

Chrysanthemum morifolium, a major cut flower worldwide, undergoes petal fading under heat stress due to reduced anthocyanin accumulation, significantly compromising its ornamental value. While previous studies have focused on heat-induced inhibition of anthocyanin biosynthesis, the mechanisms governing anthocyanin degradation remain unclear. In this study, ‘Nannong Fencui’ chrysanthemums at full bloom—when anthocyanin accumulation peaks—were exposed to 35 °C, while a control group was maintained at 22 °C, to assess heat stress effects on anthocyanin metabolism, including both biosynthesis and degradation. Transcriptomic analysis identified nine core structural genes and three key transcription factors involved in anthocyanin biosynthesis, along with twelve core genes linked to enzymatic anthocyanin degradation. Notably, the FPKM values of structural genes for anthocyanin biosynthesis were extremely low in both groups, indicating that anthocyanin biosynthesis was largely inactive at full bloom. Untargeted metabolomic analysis identified the 30 most significantly enriched metabolic pathways. Compared to the control, heat treatment led to a significant increase in 93 metabolites (FC > 1.5, p < 0.05, VIP > 1) and a significant decrease in 160 metabolites (FC < 1/1.5, p < 0.05, VIP > 1). Cyanidin glucoside, the primary anthocyanin in chrysanthemum petals, significantly decreased under heat treatment, while its potential degradation product, protocatechuic acid, was undetectable. Meanwhile, 5-carboxyvanillic acid levels significantly increased in heat-treated groups, suggesting that protocatechuic acid may have been converted into 5-carboxyvanillic acid via an O-methylation pathway. These findings provide new insights into the metabolic regulation of anthocyanins in chrysanthemums under heat stress and offer potential strategies for maintaining flower color quality during summer production, highlighting key candidate genes (CmPRXs and CmOMT1) for future functional validation and breeding efforts aimed at improving heat tolerance and color stability.

Myocardial Bridging (MB) is typically a benign congenital coronary anomaly. MB can infrequently result in complications such as myocardial ischemia, arrhythmias, and sudden cardiac death. Recent studies suggest an underlying genetic component for MB involving DES, FBN1, SCN2B, or NOTCH1. The role of percutaneous coronary intervention (PCI) in managing MB, compared to optimal medical therapy (OMT), remains uncertain. Our study used the National Inpatient Sample (NIS) Database to identify patients aged 18 or older with myocardial bridging who were managed with PCI versus medical therapy. We compared the outcomes between both groups including in-hospital mortality, the trend of management of MB and other in-hospital outcomes or complications. Our results showed no statistically significant difference between both subgroups when comparing in-hospital mortality and secondary outcomes of cardiac arrest and the development of an acute kidney injury (AKI). Patients with myocardial bridging treated with PCI had a higher risk of developing cardiogenic shock, requiring LVAD, and requiring the use of intra-aortic balloon pump (IABP) compared to the medical therapy subgroup. Our study suggests the decision to perform PCI in myocardial bridging patients should be individualized such as in patients with refractory symptoms despite medical therapy or those with known high-risk features.
