Elderly patients are a special category of patients, due to the physiological changes induced by age, the great number of comorbidities and drug treatment and last, but not least, to the cognitive dysfunction frequently encountered in this population. Cardiovascular disease is the most important cause of morbidity and mortality in elderly individuals worldwide. The rate of cardiovascular events increases after 65 years in men and after 75 years in women. Myocardial infarction and stroke are the leading disorders caused by atherosclerosis, that lead to death or functional incapacity. Elderly people have a greater risk to develop atherosclerotic cardiovascular disease. The incidence and prevalence of atherosclerosis increase with age and the number of cardiovascular events is higher in elderly patients. The most efficient treatment against atherosclerosis is the treatment with statins, that has been shown to decrease the risk both of stroke and coronary artery disease in all age groups. The advantages of the treatment become evident after at least one year of treatment. Primary prevention is the most important way of preventing cardiovascular disease in elderly individuals, by promoting a healthy lifestyle and reducing the risk factors. Secondary prevention after a stroke or myocardial infarction includes mandatory a statin, to diminish the risk of a recurrent cardiovascular event. The possible side effects of statin therapy are diabetes mellitus, myopathy, and rhabdomyolysis, hepatotoxicity. The side effects of the treatment are more likely to occur in elderly patients, due to their multiple associated comorbidities and drugs that may interact with statins. In elderly people, the benefits and disadvantages of the treatment with statins should be put in balance, especially in those receiving high doses of statins.
In the last 50 years, several clinical and epidemiological studies during have shown that increased levels of low-density lipoprotein cholesterol (LDLc) are associated with the development and progression of atherosclerotic lesions. The discovery of β-Hydroxy β-methylglutaryl-CoA reductase inhibitors (statins), that possess LDLc-lowering effects, lead to a true revolution in the prevention and treatment of cardiovascular diseases. Statins remain the cornerstone of LDLc-lowering therapy. Lipid-lowering drugs, such as ezetimibe and bile acid sequestrants, are prescribed either in combination with statins or in monotherapy (in the setting of statin intolerance or contraindications to statins). Microsomal triglyceride transfer protein inhibitors and protein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are other drug classes which have been investigated for their potential to decrease LDLc. PCSK9 have been approved for the treatment of hypercholesterolemia and for the secondary prevention of cardiovascular events. The present narrative review discusses the latest (2019) guidelines of the European Atherosclerosis Society/European Society of Cardiology for the management of dyslipidemia, focusing on LDLc-lowering drugs that are either already available on the market or under development. We also consider “whom, when and how” do we treat in terms of LDLc reduction in the daily clinical practice.
Dyslipidemia is a significant threat to public health worldwide and the identification of its pathogenic mechanisms, as well as novel lipid-lowering agents, are warranted. Magnesium (Mg) is a key element to human health and its deficiency has been linked to the development of lipid abnormalities and related disorders, such as the metabolic syndrome, type 2 diabetes mellitus, or cardiovascular disease. In this review, we explored the associations of Mg (dietary intake, Mg concentrations in the body) and the lipid profile, as well as the impact of Mg supplementation on serum lipids. A systematic search was computed in PubMed/MEDLINE and the Cochrane Library and 3649 potentially relevant papers were detected and screened (n = 3364 following the removal of duplicates). After the removal of irrelevant manuscripts based on the screening of their titles and abstracts (n = 3037), we examined the full-texts of 327 original papers. Finally, after we applied the exclusion and inclusion criteria, a number of 124 original articles were included in this review. Overall, the data analyzed in this review point out an association of Mg concentrations in the body with serum lipids in dyslipidemia and related disorders. However, further research is warranted to clarify whether a higher intake of Mg from the diet or via supplements can influence the lipid profile and exert lipid-lowering actions.

Patients with type 2 diabetes exhibit higher cardiovascular risk than normal individuals. Optimal blood glucose levels are rarely achieved in diabetic patients. Glucagon‑like peptide‑1 receptor agonists (GLP‑1 RAs) have emerged as a new antidiabetic drug class with multiple metabolic effects. Some trials have evaluated their safety, but it has been recently demonstrated that this new class has cardiovascular benefits, through other mechanisms than glycemic control. The use of GLP‑1RAs was associated with a significant reduction of cardiovascular and all‑cause mortality, with a safe profile related to pancreatitis or thyroid cancer, as compared with placebo. This review presents the cardiovascular and metabolic benefits of GLP‑1 RAs versus placebo, in patients with type 2 diabetes. Semaglutide and liraglutide demonstrated a reduction in cardiovascular events, with similar rates on cardiovascular mortality. Ongoing trials assess the cardiovascular benefits and side effects of dulaglutide treatment. Exenatide and liraglutide demonstrated the decrease of blood pressure values, weight reduction and improvement of dyslipidemia. Liraglutide induced, both in vivo and in vitro, an improvement of blood circulation, increasing the nitric oxide level and inhibiting the adhesion and procoagulant factors. Also, liraglutide demonstrated beneficial effects on cardiac remodeling after myocardial infarction, but more large trials are required. However, the international guidelines recommend using GLP‑1 RAs as first‑line therapy in type 2 diabetes patients with high cardiovascular risk or as first‑line agents in patients intolerant to metformin.
With the prevalence of digitalization in all aspects of modern society, health assessment is becoming digital too. Taking advantage of the most recent technological advances and approaching medicine from an interdisciplinary perspective has allowed for important progress in healthcare services. Digital health technologies and biotelemetry devices have been more extensively employed for preventing, detecting, diagnosing, monitoring, and predicting the evolution of various diseases, without requiring wires, invasive procedures, or face-to-face interaction with medical personnel. This paper aims to review the concepts correlated to digital health, classify and describe biotelemetry devices, and present the potential of digitalization for remote health assessment, the transition to personalized medicine, and the streamlining of clinical trials.

Penile carcinoma is a relatively frequent health issue in the developing countries such as Africa, Asia and South America, usually affecting men aged between 50 and 70 years. It is a highly treatable disease in its early stages, but has serious physical and psychological consequences. Usually, penile carcinoma is located in the penile glans, in approximately half the cases, with the most frequent histological type being squamous cell carcinoma with its microscopic subtypes. A large number of risk factors have been reported for this disease, having a multifactorial etiology, HPV infection being one of the most important factors involved in its appearance. Out of the HPV DNA positive genital cancers HPV‑16 is the most frequently found type in men, followed by HPV‑18. The evolution of penile cancer includes two independent carcinogenic pathways, related or unrelated to HPV infection. There is limited data available in literature regarding HPV‑related neoplasia, as well as on the efficacy of vaccination in men, with studies still ongoing.
