Chronic heart failure is a terminal point of a vast majority of cardiac or extracardiac causes affecting around 1–2% of the global population and more than 10% of the people above the age of 65. Inflammation is persistently associated with chronic diseases, contributing in many cases to the progression of disease. Even in a low inflammatory state, past studies raised the question of whether inflammation is a constant condition, or if it is, rather, triggered in different amounts, according to the phenotype of heart failure. By evaluating the results of clinical studies which focused on proinflammatory cytokines, this review aims to identify the ones that are independent risk factors for heart failure decompensation or cardiovascular death. This review assessed the current evidence concerning the inflammatory activation cascade, but also future possible targets for inflammatory response modulation, which can further impact the course of heart failure.

With the technological developments witnessed in recent decades, nanotechnology and nanomaterials have found uses in several common applications and products we encounter daily. On the other hand, polyurethane (PU) foams represent an extremely versatile material, being widely recognized for their extensive application possibilities and possessing a multitude of fundamental attributes that enhance their broad usability across various application fields. By combining the versatility of PU with the antimicrobial properties of nanoparticles, this emerging field holds promise for addressing the urgent need for effective antimicrobial materials in various applications. In this comprehensive review, we explore the synthesis methods, properties and applications of these nanocomposite materials, shedding light on their potential role in safeguarding public health and environmental sustainability. The main focus is on PU foams containing metal and metal oxide nanoparticles, but a brief presentation of the progress documented in the last few years regarding other antimicrobial nanomaterials incorporated into such foams is also given within this review in order to obtain a larger image of the possibilities to develop improved PU foams.

Secondary prevention after acute coronary syndromes is the key strategy to reduce the residual cardiovascular disease risk. A tailored assessment is necessary to suggest the best management and treatment for patients. Sex and gender differences should be strongly considered during cardiovascular evaluation and risk estimation. Indeed, women have a worse outcome than men and are less likely to receive appropriate treatment and evidence-based management. Proper lifestyle management, guideline-directed medical therapy, risk factor management, and cardiac rehabilitation should be recommended early after an acute event in women to reduce the high risk of recurrent events and mortality and improve quality of life. Women-focused cardiac rehabilitation and secondary prevention represent a necessary step in the management and treatment of patients to ensure the best evidence-based care after acute coronary syndromes. This review offers a critical, updated, and comprehensive overview of the appropriate strategies for secondary prevention in women after acute coronary syndromes and long-term treatment, with a focus on cardiac rehabilitation programs. Furthermore, gaps in evidence on this topic and practical recommendations will be provided.

Background: The prevalence of dental caries has increased among children, largely due to nutritional habits or inadequate access to dental care. The present study aimed to investigate the prevalence of dental caries associated with various factors that lead to their appearance, such as food intake and body composition, among Romanian school-age children from two counties, Bistriţa Năsăud and Mureş. Methods: This cross-sectional study included 1100 children aged 6–10 years from two Romanian counties. Dental caries experience was assessed using the DMFT and dmft indices based on WHO criteria. Dietary intake and oral health behaviors were evaluated through a food frequency questionnaire completed by parents. Associations between dietary variables and dental caries were assessed using independent sample t-tests and Mann–Whitney U tests. A binary logistic regression model was used to estimate the likelihood of caries in the permanent dentition (DMFT > 0), with covariates including county, parental education, daily sugar intake, consumption of dairy products, body mass index (BMI), and waist-to-height ratio. Results: It was found that the children who daily consume cheese recorded a DMFT value lower than the children who did not consume (p < 0.05). Moreover, those who consume sugary foods recorded higher values of DMFT as compared with those who did not (p < 0.05). The body weight, BMI, and waist circumference are positively correlated with DMFT, but negatively with dmft (p < 0.05). The overall prevalence of caries was 79.8% in primary dentition and 63.6% in permanent dentition, with slightly higher rates observed in Bistriţa-Năsăud County compared to Mureş. It seems that the predictors of the caries’s presence among children include the mother’s education level, sugar intake frequency, and body fat ratio. Conclusions: Based on significant associations found, one can affirm that the dental caries of the Romanian school-age children is due to sugary food intake and body composition. In addition, the direct relationship between dental caries and childhood obesity showed through the correlation of BMI and dental health indices denotes that school-age children should reduce sugary foods and increase dairy products.

Background: Chronic inflammation is a constant phenomenon which accompanies the heart failure pathophysiology. In all phenotypes of heart failure, irrespective of the ejection fraction, there is a permanent low-grade activation and synthesis of proinflammatory cytokines. Many classes of anti-remodelling medication used in the treatment of chronic heart failure have been postulated to have an anti-inflammatory effect. Methods: This retrospective study enrolled 220 patients and focused on evaluating the effect of the most used active substances from these classes in reducing the level of inflammatory biomarkers (C reactive protein, erythrocyte sedimentation rate and fibrinogen) after initiation or up-titration. Our research is evaluating if this anti-inflammatory effect intensifies while raising the dose. The evaluation was performed at two visits with an interval between them of 6 months. Results: From the beta-blockers class, carvedilol showed a reduction in erythrocyte sedimentation rate (ESR), in low (6.25 mg, bi daily) and medium (12.5 mg, bi daily) doses. At the same time, sacubitril/valsartan showed a reduction in CRP levels. This effect was obtained only in the medium (49/51 mg, bi daily) and high (97/103 mg, bi daily) doses, with the maximum reduction being observed in the high dose. Conclusions: From the classes of medication evaluated, the study showed a significant reduction in ESR levels in the low and medium doses of carvedilol and a reduction in CRP values in the cases of medium and high doses of ARNI.

Cardiac rehabilitation is strongly recommended in secondary cardiovascular prevention. In patients after coronary artery bypass grafting, this intervention is suggested to reduce mortality, morbidity, and disability. In addition, rehabilitation programs improve quality of life and cardiorespiratory fitness. Modern cardiac rehabilitation programs include structured exercise training, education, nutritional counseling, psychosocial support, and management of cardiovascular risk factors, each tailored to the specific needs of post-coronary artery bypass grafting patients who often face a high burden of comorbidities and surgical recovery challenges. For these reasons, cardiac rehabilitation should be regarded as standard of care. Evidence supports early cardiac rehabilitation initiation and individualized multidisciplinary plans, which have shown to improve exercise capacity, health-related quality of life, and medication adherence. Long-term follow-up is essential, as studies have demonstrated a clear association between sustained cardiac rehabilitation engagement and decreased rates of rehospitalization and all-cause mortality. Therefore, this comprehensive review presents recent advances and updates on the management of patients after coronary artery bypass grafting during cardiac rehabilitation, with a focus on the core components and long-term follow-up.
