Introduction: Wearable Activity Trackers (WATs) offer real-time feedback on activity levels. We assessed the impact of WAT usage on physicians’ exercise habits. Methods: Physicians from the Athens Medical Association, Greece (n = 742) responded to a self-administered questionnaire evaluating usage of WAT, demographic characteristics, specialty, and physical exercise habits. WHO guidelines recommend at least 150 min/week of moderate-intensity exercise in all healthy adults. Subjects were divided in Users of WATs (Group A), and Non-Users of WATs (Group B). This is an observational, cross-sectional study. Results: There was no difference in baseline characteristics between the two groups (age, sex, body mass index). WATs were used by 38%. Between Group A and B, there was difference in mean exercise training time (302 ± 304 min vs. 210 ± 268 min, p < 0.001), higher percentage of WHO goal achievement (66.3% vs. 50.7%, p < 0.001), and greater awareness of WHO Guidelines (59.9% vs. 47.4%, p < 0.001). WATs were mostly used by four main specialties, with higher use from Cardiologists: Cardiology (47%), Endocrinology (44%), Surgery (35%) and Internal Medicine (25%), with a p = 0.045. Finally, users of WATs compared to non-users showed higher willingness to reduce body weight (58.5% vs. 48%, p = 0.01), apply dietary restrictions (36.5% vs. 29.6%, p = 0.05), and greater motivation for weekly physical exercise (74.1% vs. 32.4%, p < 0.001); Conclusion: Physicians using WATs demonstrate increased exercise training time, greater awareness of WHO guidelines and a higher propensity to implement dietary restrictions compared to non-users. Variations in WAT usage across medical specialties emphasize the need for targeted interventions to promote physical activity and enhance healthcare professionals’ health.

The burden of cardiovascular diseases and the critical role of acute coronary syndrome (ACS) in their progression underscore the need for effective diagnostic and prognostic tools. Biomarkers have emerged as crucial instruments for ACS diagnosis, risk stratification, and prognosis assessment. Among these, high-sensitivity troponin (hs-cTn) has revolutionized ACS diagnosis due to its superior sensitivity and negative predictive value. However, challenges regarding specificity, standardization, and interpretation persist. Beyond troponins, various biomarkers reflecting myocardial injury, neurohormonal activation, inflammation, thrombosis, and other pathways are being explored to refine ACS management. This review article comprehensively explores the landscape of clinically used biomarkers intricately involved in the pathophysiology, diagnosis, and prognosis of ACS (i.e., troponins, creatine kinase MB (CK-MB), B-type natriuretic peptides (BNP), copeptin, C-reactive protein (CRP), interleukin-6 (IL-6), d-dimers, fibrinogen), especially focusing on the prognostic role of natriuretic peptides and of inflammatory indices. Research data on novel biomarkers (i.e., endocan, galectin, soluble suppression of tumorigenicity (sST2), microRNAs (miRNAs), soluble oxidized low-density lipoprotein receptor-1 (sLOX-1), F2 isoprostanes, and growth differentiation factor 15 (GDF-15)) are further analyzed, aiming to shed light on the multiplicity of pathophysiologic mechanisms implicated in the evolution of ACS. By elucidating the complex interplay of these biomarkers in ACS pathophysiology, diagnosis, and outcomes, this review aims to enhance our understanding of the evolving trajectory and advancements in ACS management. However, further research is necessary to establish the clinical utility and integration of these biomarkers into routine practice to improve patient outcomes.

Abstract Background Comorbidities and adherence to inhaled therapy appears to have a major impact on treatment goals, health status and disease control in chronic obstructive pulmonary disease (COPD). Aim of the study was to assess levels of adherence to inhalers, comorbidities and associations with COPD outcomes in patients residing in rural and semi-urban areas of Greece. Methods Two hundred fifty-seven COPD patients were enrolled from primary health care in 2015–2016. Physicians used structured interviews and questionnaires to assess quality of life and disease status. Patients were classified into groups according to GOLD 2019 guidelines (based on CAT and mMRC). Adherence to inhalers was measured with the Test of Adherence to Inhalers (TAI). Multivariate linear and logistics regression models were used to assess associations between comorbidities and adherence to inhalers with COPD outcomes, including CAT and mMRC scores, exacerbations and GOLD A-D status. Results 74.1% of COPD patients reported poor adherence, while most of them were characterized as deliberate non-compliers (69.5%). 77.1% had ≥2 comorbidities, with overweight/obese (82.2%), hypertension (72.9%) and diabetes mellitus (58%) being the most prevalent. In multivariate analysis, COPD outcomes having significant associations with poor adherence included worse health status [OR (95% CI) 4.86 (1.61–14.69) and 2.93 (1.51–5.71) based on CAT and mMRC, respectively], having ≥2 exacerbations in the past year [4.68 (1.51–4.44)], and disease status e.g., be in groups C or D [3.13 (1.49–8.53) and 3.35 (1.24–9.09) based on CAT and mMRC, respectively). Subjects with gastroesophageal reflux showed better inhaler adherence [OR (95% CI) 0.17 (0.6–0.45)], but none of the comorbid conditions was associated with COPD outcomes after adjustments. Conclusions Poor adherence to inhalers and comorbidities are both prevalent in COPD patients of primary care residing in rural/semi-urban areas of Greece, with adherence influencing COPD outcomes. Raising awareness of patients and physicians on the importance of comorbidities control and inhaler adherence may lead to interventions and improve outcomes.

Over the last decades, significant advances have been achieved in the treatment of coronary artery disease (CAD). Proper non-invasive diagnosis and appropriate management based on functional information and the extension of ischemia or viability remain the cornerstone in the fight against adverse CAD events. Stress echocardiography and single photon emission computed tomography are often used for the evaluation of ischemia. Advancements in non-invasive imaging modalities such as computed tomography (CT) coronary angiography and cardiac magnetic resonance imaging (MRI) have not only allowed non-invasive imaging of coronary artery lumen but also provide additional functional information. Other characteristics regarding the plaque morphology can be further evaluated with the latest modalities achieving a morpho-functional evaluation of CAD. Advances in the utilization of positron emission tomography (PET), as well as software advancements especially regarding cardiac CT, may provide additional prognostic information to a more evidence-based treatment decision. Since the armamentarium on non-invasive imaging modalities has evolved, the knowledge of the capabilities and limitations of each imaging modality should be evaluated in a case-by-case basis to achieve the best diagnosis and treatment decision. In this review article, we present the most recent advances in the noninvasive anatomical and functional evaluation of CAD.

Abstract Background Frailty is a state of increased vulnerability that has a significant risk of unfavorable outcomes such as increased dependency and/or death, but little is known about frailty in people with chronic obstructive pulmonary disease (COPD). Method We aimed to determine the prevalence of frailty in COPD patients and to identify the associated risk factors. Two hundred fifty-seven COPD patients enrolled from primary care in Greece between 2015 and 2016. Physicians used structured interviews to collect cross-sectional data including demographics, medical history, symptoms and COPD Assessment Tool (CAT) or modified Medical Research Council Dyspnea scale (mMRC) score. Patients were classified into severity groups according to GOLD 2017 guidelines. Participants completed the The Frail Non-Disabled (FiND) questionnaire, exploring the frailty and disability domains. In the present analyses, frail patients with and without mobility disability were pooled and were compared to non-frail patients. Factors associated with frailty were analyzed using univariate and multivariate logistic regression. Results Mean (SD) age was 65 (12.3) with 79% males. The majority of patients suffered with frailty (82%) of which 76.8% had mobility disability. 84.2% were married/with partner and 55.4% retired. 55.6% were current smokers. Uncontrolled disease (≥10 CAT score) was reported in 91.1% and 37.2% of patients had ≥2 exacerbations in the past year. Dyspnea (38%) and cough (53.4%) were the main symptoms. Main comorbidities were hypertension (72.9%), hyperlipidaemia (24.6%) and diabetes (11%). Risk of frailty was significantly increased with age (OR; 95%CI: 1.05; 1.02–1.08), hypertension (2.25; 1.14–4.45), uncontrolled disease (≥10 CAT score 4.65; 1.86–11.63, ≥2 mMRC score 5.75 (2.79–11.85) or ≥ 2 exacerbations 1.73; 1.07–2.78), smoking cessation (ex compared to current smokers: 2.37; 1.10–5.28) and GOLD status (B&D compared to A&C groups: CAT-based 4.65; 1.86–11.63; mMRC-based: 5.75; 2.79–11.85). In multivariate regression smoking cessation and GOLD status remained significant. Gender, body mass index, occupational or marital status, symptoms and other comorbidities were not significant. Conclusions Frailty with mobility disability is common in COPD patients and severity of disease increases the risk. It is possible that frail patients are more likely to quit smoking perhaps because of their disability and uncontolled disease. Routine assessment of frailty in addition to COPD control may allow early interventions for preventing or delaying progression of frailty and improvement in COPD disease.

Overt aseptic meningitis rarely complicates varicella-zoster virus (VZV) reactivation in young and immunocompetent adults. Many of the cases of VZV meningitis are associated with an exanthem. We describe an otherwise healthy 36-year-old adult who had aseptic meningitis without skin rash, caused by reactivation of varicella-zoster virus. Cerebrospinal fluid (CSF) analysis revealed lymphocytosis, increased total protein, and low glucose. Diagnosis was made by polymerase chain reaction in CSF. The present case highlights the fact that VZV should be considered as a cause of aseptic meningitis with hypoglycorrhachia in healthy and young individuals, even in the absence of an exanthem.

Myocarditis is the inflammation of the heart muscle and it is caused by a wide range of infectious and non-infectious conditions. Non-typhoidal Salmonella infection, a common foodborne illness worldwide, only rarely causes myocarditis. We describe a case of an immunocompetent adult with Salmonella enterica myocarditis who had a favorable outcome due to early recognition of the causative factor and prompt initiation of appropriate treatment.
