Background. Overweight and obesity often develop in individuals with genetic susceptibility and concomitant risk factors; however, medications can represent precipitating factors in some cases: evidence suggests that some antihypertensive drugs can adversely affect energy homeostasis and metabolism. Aim. The primary aim of this study was to investigate whether long-term therapy with a beta blocker impairs weight loss during a period of appropriate personalized hypocaloric diet and standardized physical activity in overweight and obese hypertensive patients in monotherapy and without comorbidities, compared to other antihypertensive drugs and to a control group not taking antihypertensive therapy. Subjects and Methods. We enrolled overweight and obese patients taking antihypertensive drugs; subjects were divided into 3 groups: those taking traditional beta blockers (bB group), those taking third-generation beta blockers (bB-3 group), and those taking other antihypertensive drugs (non-bB group). We also enrolled subjects receiving neither antihypertensive therapy nor other chronic medication in the prior 12 months as controls. All subjects underwent personalized hypocaloric diets for a period of 24 months with monthly follow-up. Anthropometric parameters were measured at enrollment and then monthly after diet prescription. Glucose and lipid values were assessed at baseline and at 12 and 24 months during dietary regimen. Results. We enrolled a total of 120 overweight and obese patients aged 50.30±1.13 years (mean±standard deviation) with a mean BMI of 31.79±0.65kg/m²; 90 were taking antihypertensive drugs (no comorbidity and no polytherapy), while 30 subjects receiving neither antihypertensive therapy nor other chronic medication in the prior 12 months were considered as controls. After 6 months, the percent total weight loss (TWL) was lower in the bB group (3.62±1.96 versus 5.27±1.76 in the bB-3 group, versus 5.15±1.30 in the non-bB group, and versus 4.70±0.87 in the control group), as well as their BMI. After 24 months, we kept finding the worst result in the bB group (TWL=9.22±2.19 versus 12.79±1.72 in the non-bB group and 12.28±1.97 in the control group) with the best trend in the bB-3 group (TWL=16.19±2.67).

Micro- and nanoplastics (MNPs) are increasingly recognized as pervasive environmental contaminants with profound implications for ecosystems and human health. Their small size, compositional diversity, and occurrence across complex matrices—including water, soil, food, and biological samples—pose substantial analytical challenges. Conventional techniques such as vibrational spectroscopy, chromatographic analysis, and electron microscopy have yielded critical insights into MNP composition, morphology, and distribution; however, these methods often face limitations in sensitivity, throughput, and adaptability to real-world samples. Recent advances in nanotechnology have catalyzed the emergence of nanodevices—encompassing nanosensors, nanopore systems, integrated lab-on-a-chip platforms and nanostructured capture materials—that promise enhanced sensitivity, specificity, and the capacity for real-time, in situ detection. These innovations not only facilitate high-throughput analysis but also provide novel opportunities for integrated characterization of MNPs across diverse matrices. This review synthesizes the current state of nanodevice-based MNP detection, critically examining their principles, performance, and limitations relative to conventional approaches, and outlining the key needs for standardization, matrix-specific adaptation, and regulatory harmonization.

Bronchial asthma is a chronic inflammatory airway disease involving many cells and mediators. Chronic inflammation constitutes an important predisposing condition for airway remodelling with secondary irreversible airflow obstruction. Current approaches for asthma treatment involve many classes of drugs, adequate patient education for their correct use, environmental exposure control and daily monitoring of pulmonary function. Unfortunately, the use of multiple therapies complicates treatment regimens, thus leading to a reduced compliance to therapy. Available evidence from randomised clinical trials and real-word experience derived from managing patients with asthma justifies a broader role for leukotriene receptor antagonist drugs in asthma management than that recommended in the National Asthma Education and Prevention Programme and National Health Lung and Blood Institute Treatment Guidelines. While a low dose of inhaled corticosteroids remains the reference drug as a controller in mild-to-moderate persistent asthma, oral therapy with an leukotriene-receptor antagonist drug represents a good option providing the clinical efficacy requested in common clinical practice. For this reason the recent Global Initiative for Asthma Guidelines allocate this drug to the second and third steps of asthma treatment.

Objectives: Recent evidence indicates that rosuvastatin 40 mg may exert a beneficial effect in both carotid and coronary atherosclerosis progression. In particular, 2-year rosuvastatin treatment reduced the progression of carotid intima-media thickness (cIMT) in patients with low cardiovascular risk. However, despite the fact that in clinical practice lower doses of rosuvastatin are usually administered at this time, there are no clear data about its effect on cIMT. Thus, the aim of this study was to evaluate the effect of rosuvastatin 10 mg/day on cIMT over a 2-year follow-up. Methods: Forty-five patients with hypercholesterolemia and asymptomatic carotid atherosclerosis on baseline carotid ultrasound investigation were treated with rosuvastatin 10 mg/day for 24 months. cIMT and lipid profile were assessed after 12 months and at the end of the study (24 months). Results: After 24 months, the treatment showed a 35.67% reduction in low-density lipoprotein cholesterol concentration (171 vs 110 mg/dl; p < 0.001), a 32.27% reduction in total cholesterol (251 vs 170 mg/dl; p < 0.001), a 19.67% increase in high-density lipoprotein cholesterol concentration (49 vs 61 mg/dl; p < 0.001), and a 10% reduction in triglycerides (120 vs 108 mg/dl; p < 0.01). Rosuvastatin treatment was associated with a 26.6% reduction in left cIMT (1.20 vs 0.90 mm; p < 0.001) and a 22.2% reduction in right cIMT (1.22 vs 0.95 mm; p < 0.001). Conclusion: Two-year treatment with rosuvastatin 10 mg/day in hypercholesterolemic adults with evidence of subclinical atherosclerosis establishes a significant reduction in cIMT and improves lipid and lipoprotein levels, with a good tolerability profile.

The interrelation between arrhythmias and lifestyle factors is acknowledged. On the one side, there is a recognized interaction between atrial fibrillation and obesity, hypertension, dyslipidemia and type 2 diabetes mellitus. Saturated fats, excessive added salt, tea, coffee and energy drinks are often deleterious in rhythm disorders. The role of others, such as cocoa-rich foods, is less evident: several authors displayed the beneficial effect of the polyphenols content on numerous cardiovascular risk factors, while little is known about the potential link between diet and incident arrhythmias. Arrhythmias’ most frequent risk factors include aging, hypertension, congenital cardiopathy, heart failure, valvulopathy, thyroid diseases and diabetes. Nevertheless numerous arrhythmias are not related to any of these risk factors: in these cases, immunological, functional and even nutritional mechanisms might be involved in dysrhythmias’ genesis. Aim of this narrative review is to analyze the potential adverse effect of cocoa excessive consumption on cardiac rhythm and its mechanisms and to provide state-of-the-art knowledge on this topic.
