Non-Pharmacological Intervention for Personalizing Sleep Quality through Gentle Rocking Motion.

INTRODUCTION: Achieving restorative sleep is crucial for overall well-being, yet sleep difficulties affect a substantial portion of the adult population. Sleep disturbances are associated with diminished quality of life, physical complaints, cognitive impairment, and emotional regulation challenges. OBJECTIVE: This study explores the influence of an innovative experimental bed designed to generate rocking motions on sleep parameters. METHODS: A prospective observational study enrolled 60 adult participants, assessing their sleep on a regular stationary bed and the Inoveris bed, providing gentle rocking movements. Polysomnography was conducted, recording electroencephalography, electrooculogram, electromyogram, respiratory effort, and other parameters. RESULTS: The rocking bed significantly increased total sleep time (TST) and reduced N1 sleep stage duration (p < 0.001). Participants also experienced a quicker transition to the N2 sleep stage (p = 0.01), indicative of a faster shift from wakefulness to deeper sleep. Additionally, rocking led to a higher percentage of N1 sleep stages (p = 0.01) and a significant increase in N3 sleep stage duration (p = 0.004). While some results lacked statistical significance, notable trends in the rocking bed group have clinical relevance, consistently improving sleep parameters, including increased TST. The rocking bed also showed a trend towards higher sleep efficiency (SE) and sleep duration percentage, hinting at a potential overall enhancement in sleep quality. CONCLUSION: This study contributes valuable insights into the potential benefits of rocking motions on sleep architecture. Despite variations in outcomes across studies, our results underscore the potential of rocking beds as a non-pharmacological intervention for enhancing sleep quality. Notable improvements in total sleep time (TST), N1 sleep stage reduction, and accelerated transitions to deeper sleep stages highlight the clinical relevance of rocking interventions. Further research, collaboration, and addressing the identified limitations will advance our understanding of the therapeutic applications of rocking motions in sleep science.

Morphological aspects of basal cell carcinoma vascularization.

Basal cell carcinoma (BCC) is a malignant skin cancer which commonly exhibits aberrant blood flow because of angiogenesis. Its invasiveness and lack of metastatic potential may be explained by the typical pattern of vascularization seen in BCCs, where blood vessels are absent in the tumor islands and prominent in the tumor's periphery. From clinical point of view, high-frequency ultrasound (HFUS) is a useful tool for the evaluation of the lateral and depth extension of these tumors; furthermore, by employing color Doppler, important data regarding the vascularization degree of BCCs is provided. Knowingly, the sonographic vascular pattern of cutaneous tumors can aid in improving diagnosis and treatment by differentiating between benign and malignant lesions, between various types of cutaneous malignancies and also between various types of BCC (e.g., low risk versus high risk). Our aim was to perform a review integrating all currently known vascular properties of BCC as a tumor entity.

Arguments for Using Direct Oral Anticoagulants in Cancer-Related Venous Thromboembolism.

(1) Background: Patients with cancer with a hypercoagulable state present an increased incidence of venous thromboembolism (VTE). Neoplastic patients with concurrent VTE undergoing anticoagulant treatment face a series of issues. (2) The aim of the present paper is to systematically summarize current VTE management in patients with neoplasia and to review the current clinical evidence from meta-analyses of randomized controlled trials and guidelines regarding the administration of direct oral anticoagulants (DOACs) for cancer-associated VTE. (3) Search Strategy: We performed a review on meta-analyses of randomized controlled trials and guidelines in favor of the administration of DOACs in patients with cancer-associated VTE published in the last 6 years in the Medline (PubMed) and Embase databases. (4) Results: 21 meta-analyses, 14 randomized controlled studies comparing DOACs to VKAs and LMWH, and 7 national and international guidelines were identified. We identified five studies that show the antineoplastic effect of DOAC on experimental models. (5) Conclusions: DOACs can be seen as the first choice for VTE treatment in neoplastic patients who have a low risk of bleeding, who do not have severe renal impairment, and who are not undergoing treatments that could interact with DOAC's mechanism of action.

A Prospective Study of CPAP Therapy in Relation to Cardiovascular Outcome in a Cohort of Romanian Obstructive Sleep Apnea Patients.

BACKGROUND: Despite efforts at treatment, obstructive sleep apnea (OSA) remains a major health problem, especially with increasing evidence showing an association with cardiovascular morbidity and mortality. The treatment of choice for OSA patients is Continuous Positive Airway Pressure (CPAP), which has been proven in randomized controlled trials to be an effective therapy for this condition. The impact of CPAP on the cardiovascular pathology associated with OSA remains, however, unclear. Although the effect of CPAP has been previously studied in relation to cardiovascular outcome, follow-up of the treatment impact on cardiovascular risk factors at one year of therapy is lacking in a Romanian population. Thus, we aimed to evaluate the one-year effect of CPAP therapy on lipid profile, inflammatory state, blood pressure and cardiac function, assessed by echocardiography, on a cohort of Romanian OSA patients. METHODS: We enrolled 163 participants and recorded their baseline demographic and clinical characteristics with a follow-up after 12 months. Inflammatory and cardiovascular risk factors were assessed at baseline and follow up. RESULTS: Our results show that CPAP therapy leads to attenuation of cardiovascular risk factors including echocardiographic parameters, while having no effect on inflammatory markers. CONCLUSION: Treatment of OSA with CPAP proved to have beneficial effects on some of the cardiovascular risk factors while others remained unchanged, raising new questions for research into the treatment and management of OSA patients.

ACE2 and Apelin-13: Biomarkers with a Prognostic Value in Congestive Heart Failure.

The progression of heart failure is the result of the interaction of several pathogenetic processes that involve the activation of biomarkers belonging to the renin angiotensin aldosterone system (RAAS), to its counterregulatory mechanisms, to the sympathetic nervous system and inflammation, and to oxidative stress. This study is aimed at determining the prognostic role of biomarkers in the evolution of patients with heart failure. These biomarkers are representative of different pathogenetic pathways involved in the progression of heart failure and the possible interrelationships between them and heart remodelling. Method. This is a progressive observational study on 53 hospitalized patients with low ejection fraction heart failure, who were followed up for 12 months. The aetiology of heart failure was ischemic heart disease and dilated cardiomyopathy. The patients were clinically and biochemically evaluated by EKG (echocardiography) on admission and at 6 and 12 months. The biomarkers included in the present study were angiotensin-converting enzyme type 2 (ACE2), apelin-13, NT-proBNP (biomarkers involved in the counterregulation of RAAS), interleukin 17 (IL-17), hsCRP (inflammatory biomarkers), and urinary 8-iso-PGF2α (oxidative stress biomarker). The evolution was considered unfavourable if the patients presented complications during hospitalization, were readmitted for decompensated heart failure, or died. Results. From the study group, 14 patients (24.52%) presented an unfavourable clinical evolution. The biomarkers that were associated with the evolution of patients during hospitalization were ACE2, apelin-13, NT-proBNP, and hsCRP. Multivariate logistic regression analysis identified ACE2 and apelin-13 as independent, predictive biomarkers for the unfavourable evolution of patients over the study period. Values of ACE2 above 4000.75 pg/mL and of apelin-13 less than 402.5 pg/mL were associated with an unfavourable evolution (poor clinical outcomes). Conclusion. The serum values of ACE2 and apelin-13 correlate with the unfavourable evolution of patients with reduced ejection fraction heart failure.

Short-Term Prognosis Value of sST2 for an Unfavorable Outcome in Hypertensive Patients.

BACKGROUND: sST2 represents a useful biomarker for the diagnosis and prognosis of patients with heart failure, but limited data is available on its role in patients with hypertension. The aim of this study is to evaluate the short-term prognosis value of sST2 for an unfavorable outcome in hypertensive patients. METHODS: This was a prospective observational study which enrolled 80 patients with hypertension, who were followed for one year. All patients underwent clinical, laboratory (including sST2), and echocardiographic assessment at baseline. The patients were grouped according to the cardiovascular (CV) events reported during the follow-up: group A (with CV events) and group B (without CV events). RESULTS: Overall, 59 CV events were reported during the follow-up period. Compared to group B, the patients in group A had significantly higher sST2 levels, a higher number of CV risk factors, and a higher left ventricle mass. Except for the diastolic dysfunction parameters, the echocardiographic findings were similar in the two groups. Patients in group A had a lower E/A ratio, larger deceleration time, and increased telediastolic pressure as quantified by the E/E/p = 0.006, Kaplan-Meier analysis). CONCLUSIONS: sST2 levels were correlated with the risk of adverse CV outcomes in hypertensive patients and may represent a useful prognostic marker in these patients.

Biomarkers of Inflammation in Left Ventricular Diastolic Dysfunction.

Left ventricular diastolic dysfunction (LVDD) is an important precursor to many different cardiovascular diseases. Diastolic abnormalities have been studied extensively in the past decade, and it has been confirmed that one of the mechanisms leading to heart failure is a chronic, low-grade inflammatory reaction. The triggers are classical cardiovascular risk factors, grouped under the name of metabolic syndrome (MetS), or other systemic diseases that have an inflammatory substrate such as chronic obstructive pulmonary disease. The triggers could induce myocardial apoptosis and reduce ventricular wall compliance through the release of cytokines by multiple pathways such as (1) immune reaction, (2) prolonged cell hypoxemia, or (3) excessive activation of neuroendocrine and autonomic nerve function disorder. The systemic proinflammatory state causes coronary microvascular endothelial inflammation which reduces nitric oxide bioavailability, cyclic guanosine monophosphate content, and protein kinase G (PKG) activity in adjacent cardiomyocytes favoring hypertrophy development and increases resting tension. So far, it has been found that inflammatory cytokines associated with the heart failure mechanism include TNF-α, IL-6, IL-8, IL-10, IL-1α, IL-1ß, IL-2, TGF-ß, and IFN-γ. Some of them could be used as diagnosis biomarkers. The present review aims at discussing the inflammatory mechanisms behind diastolic dysfunction and their triggering conditions, cytokines, and possible future inflammatory biomarkers useful for diagnosis.

Plasma leptin, but not resistin, TNF-α and adiponectin, is associated with echocardiographic parameters of cardiac remodeling in patients with coronary artery disease.

The aim of this research was to assess the relationship between plasma adiponectin, leptin, resistin, tumor necrosis factor alpha (TNF-α) levels and echocardiographic parameters of ventricular remodeling in patients with coronary artery disease, without acute myocardial infarction. The study population consisted of 49 patients with echocardiographic measurements performed. After adjustment for age, gender, body mass index, systolic and diastolic blood pressure, and glycaemia, adiponectin was statistically significant associated with interventricular septum thickness (ß = -0.304), left ventricular posterior wall thickness (ß = -0.402), left ventricular end diastolic diameter (LVEDD; ß = 0.385) and left ventricular relative wall thickness (ß = -0.448, p < .05 for all). The associations were no longer significant when only patients without diabetes were included in the analysis. Leptin was associated with LVEDD (ß = -0.354) and left ventricular relative wall thickness (ß = 0.385, p < .05 for all). No associations between resistin, TNF-α and echocardiographic left ventricular parameters assessed were found in these patients. In conclusion, in patients with coronary artery disease and without acute myocardial infarction leptin may represent a potential mechanism of adverse cardiac remodeling. Resistin and TNF-α might not be involved in ventricular remodeling in these patients.

Serum Soluble ST2 and Diastolic Dysfunction in Hypertensive Patients.

BACKGROUND: Echocardiographic evaluation of left ventricular (LV) structural and functional alterations in hypertension has some limitations, potentially overcome by using biomarkers. ST2, a prognostic biomarker for heart failure and myocardial infarction patients, was less studied in hypertension. AIM: To analyze the relationship between serum ST2 levels and diastolic dysfunction (DD) in hypertension. METHOD: We enrolled 88 hypertensive outpatients (average age 65 years, 69.3% females) in a prospective study, stratified for presence of LV hypertrophy (LVH). For each patient clinical examination, lab workup (routine and serum ST2 levels) and echocardiography were performed. RESULTS: Hypertensive patients with LVH had higher age, pulse pressure, mean arterial pressure, and serum ST2, while having lower serum albumin than those without LVH. Serum ST2 levels correlate with parameters of LV remodeling and DD. We found that 5.3% of ST2 level variability was caused by a 1-unit variation of cardiovascular risk. We identified cut-off values for discriminating hypertension with LVH versus that without LVH and grade 2 DD versus normal diastolic performance. CONCLUSION: ST2 could be used as diagnostic biomarker for cardiac remodeling and altered diastolic performance in hypertension, providing additional data to echocardiography. It could represent a milestone in early detection of cardiac performance alteration.

Better prognosis in overweight/obese coronary heart disease patients with high plasma levels of leptin.

BACKGROUND AND AIM: The involvement of leptin in atherosclerosis is very complex, including inflammation, the oxidative stress and thrombosis. Leptin has atherogenic and also antiatherogenic actions. In obesity elevated leptin levels are not sufficient to prevent disturbances of energy balance, suggesting that obese people are leptin resistant. The aim of the study was to investigate the relationship between baseline plasma levels of leptin and the incidence of new ischemic events in patients with CHD. METHODS: Plasma levels of leptin in fifty nine consecutive patients (29 men and 30 women) with CHD hospitalized in the County Emergency Clinical Hospital of Cluj-Napoca were measured using commercially available ELISA at admission. Patients with active infectious disease, neoplasia, acute coronary syndrome, stroke, hepatic or renal failure and severe heart failure were excluded The relationship between leptin levels and incident cardiovascular events (angina, nonfatal myocardial infarction or heart failure) over two years follow-up was studied using MEDCALC version 9.6. RESULTS: 73.6% patients with CHD were overweight or suffered of obesity. There were no significant differences between women and men regarding the plasma levels of leptin, the body mass index (BMI), the number of rehospitalizations, rehospitalizations/patient, diabetes mellitus, hypertension or dyslipidemia. Only in women plasma levels of leptin are correlated with BMI. As compared with men with overweight and obesity (BMI≥25kg/m(2)), plasma levels of leptin were significantly higher in women with overweight and obesity (3905.97±463.91 pg/ml vs 1835.17±533.9 pg/ml) (p<0.002). Patient gender could not be demonstrated to influence prognosis. During the two years we recorded one or more readmissions in 26 patients (44%). The analysis of time till readmission using Kaplan-Meier curves, showed that leptin level (cut-off 2000 pg/ml, HR 0.38, 95% CI 0.17-0.83; p=0.01) and BMI (cut-off 28 kg/m(2), HR 0.3164, 95% CI 0.145-0.0689; p<0.01) were significantly associated with prognosis. CONCLUSION: Patients with plasma levels of leptin >2000 pg/ml and BMI >28kg/m(2) had a better prognosis, suggesting a protective role of leptin in overweight/mild obesity.
