Respiratory syncytial virus (RSV) is a respiratory virus that usually causes mild upper respiratory tract symptoms. However, it can lead to a severe lower respiratory tract disease in high-risk populations, with severe complications such as pneumonia and respiratory failure. RSV poses a significant public health threat not only to children, but also to adults, particularly those over 75 years of age and individuals with comorbidities.

Article Synopsis
  • Frailty is a significant geriatric syndrome affecting older adults, particularly influencing their surgical and oncological care, especially in cases of renal masses or renal cell carcinoma (RCC).
  • A review of literature highlighted that frailty is a negative prognostic factor that can impact treatment outcomes; screening tools like the G8 and Mini-COG are essential for assessing older patients and guiding comprehensive evaluations by geriatricians.
  • Integrating geriatricians into multidisciplinary tumor boards and creating specific care pathways for frailty assessment can enhance individualized treatment strategies and improve clinical outcomes for older patients with RCC.

Arterial hypertension is a major risk factor for cardiovascular morbidity and mortality, and highly prevalent in older age, underscoring the importance of its appropriate management. The population is ageing at an increasing rate, with those aged 80+ years being the fastest growing population characterized by high heterogeneity in terms of functionality and autonomy. The prevalence of hypertension rises with increasing age, due to a significant increase in SBP largely as a result of age-related stiffening of the aorta and other large arteries, affecting almost 80% of those aged 80+ years.

Aortic stenosis (AS) represents a notable paradigm for cardiovascular (CV) and geriatric disorders owing to comorbidity. Transcatheter aortic valve replacement (TAVR) was initially considered a therapeutic strategy in elderly individuals deemed unsuitable for or at high risk of surgical valve replacement. The progressive improvement in TAVR technology has led to the need to refine older patients' stratification, progressively incorporating the concept of frailty and other geriatric vulnerabilities.

Introduction: Increasing evidence supports the implementation of geriatric assessment in the workup of older patients with aortic stenosis (AS). In 2012, an online European survey revealed that geriatricians were rarely involved in the assessment of candidates for transcatheter aortic valve implantation (TAVI). After a "call to action" for early involvement of geriatricians in AS evaluation, the survey was repeated in 2022.

Article Synopsis
  • - This study analyzed the link between metabolically healthy overweight/obese adults and major cardiovascular events (MACE) using data from 15,904 participants over 11.8 years, focusing on how LDL-cholesterol levels affect this relationship.
  • - Among participants younger than 70, being overweight/obese raised the risk of MACE significantly, while older adults had a lower risk despite having high BMI.
  • - Including LDL-cholesterol in the definition of healthy metabolism showed that metabolically healthy overweight/obese individuals have no increased risk of MACE compared to normal weight individuals, challenging standard assessments of health risk.

High levels of serum uric acid (SUA) and triglycerides (TG) might promote high-cardiovascular-risk phenotypes, including subclinical atherosclerosis. An interaction between plaques xanthine oxidase (XO) expression, SUA, and HDL-C has been recently postulated. Subjects from the URic acid Right for heArt Health (URRAH) study with carotid ultrasound and without previous cardiovascular diseases (CVD) (n = 6209), followed over 20 years, were included in the analysis.

Several studies have detected a direct association between serum uric acid (SUA) and cardiovascular (CV) risk. In consideration that SUA largely depends on kidney function, some studies explored the role of the serum creatinine (sCr)-normalized SUA (SUA/sCr) ratio in different settings. Previously, the URRAH (URic acid Right for heArt Health) Study has identified a cut-off value of this index to predict CV mortality at 5.
