Deficiencies in B-vitamins have recently been recognized as risk factors for stroke and dementia. With increasing age there is an increased prevalence of metabolic and nutritional changes leading to increased vulnerability of vitamin deficiency. Especially in geriatric patients, these changes can have effects on the nervous system that are often not recognized. Often, however, vitamins in particular are taken uncritically and attributed with a variety of unspecific properties.With regard to the knowledge about the water-soluble B vitamins (B6, B12, folic acid and homocysteine as well as B1), there have recently been new findings and recommendations by various professional societies. An overview of the basics, causes, diagnostic and therapeutic concepts of B-vitamins and the current state of research in this area is given.Over the past decades, non-alcoholic fatty liver disease (NAFLD) has emerged as the leading cause of chronic liver diseases in western societies. While the complications of NAFLD progression and particularly non-alcoholic steatohepatitis (NASH) have been widely recognized and statistically proven by emerging numbers of NASH related cirrhosis, transplantations and liver cancer, simple steatosis was widely recognized as a rather benign manifestation of NAFLD. However, emerging data suggests simple steatosis to be associated with increased mortality, related to hepatic- and extrahepatic manifestations of multiple metabolic and inflammatory complications of the disease. This brief review focusses on novel aspects related to the pathogenesis and clinical relevance of simple steatosis. Based on these findings, we recommend a thorough interdisciplinary approach to patients with simple steatosis by dedicated specialized centers. The rising prevalence demands the implementation and evaluation of non-invasive screening methods and multidisciplinary preventive approaches, as according to current data, we face an epidemic of hepatic steatosis in over 25 % of the population.Over the past years, a growing demand for testosterone replacement therapy in aging men has been noted in the US as well as in Europe. The current evidence for detrimental consequences of low testosterone in old men is largely based on retrospective studies. On the other hand, prospective placebo-controlled randomized trials investigating clinically relevant endpoints are limited. Clinical benefits of testosterone replacement therapy in ageing men include improved sexual function and libido, increase in muscle mass and -function, as well as bone mass accrual. Whether testosterone supplementation in ageing men confers an altered risk for cardiovascular disease and/or prostate cancer remains unclear. TED-347 Ongoing clinical trials (e. g. TRAVERSE trial, NCT03 518 034) will help to resolve these questions.Patients with lower extremity arterial disease are at increased risk for cardiovascular events. Antithrombotic therapy improves prognosis in these patients especially after peripheral revascularization. After endovascular revascularization duale anti-platelet therapy with Aspirin and Clopidogrel is used for up to 3 months in most cases, although there is only little evidence for this practice. Following peripheral bypass grafting most guidelines recommend single anti-platelet therapy. In some patients, anticoagulation with Vitamin K antagonists or dual anti-platelet therapy is indicated. But this practice is also based on small studies. The Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease (VOYAGER PAD) study is the largest randomized trial concerning antithrombotic therapy after peripheral revascularization. In total 6564 patients were included after successful surgical or endovascular lower-extremity revascularization. Rivaroxaban 2.5 mg twice daily plus Aspirin 100 mg reduced cardiac and peripheral events compared with Aspirin 100 mg alone with increased risk for relevant but not for critical bleeding complications. In addition to antithrombotic medication risk factor management and regular follow-up examinations are important improve long-term prognosis after peripheral revascularization.There is a paucity of data on the relation between serum 25-hydroxyvitamin D [25(OH)D] concentration and cardiometabolic biomarkers in the Chinese population. To comprehensively and quantitatively examine the association of 25(OH)D and cardiometabolic traits, we conducted a cross-sectional study in the Chinese rural population. Serum 25(OH)D and eight cardiometabolic biomarkers were measured in 1714 individuals from Henan province, China. Scatter plot was used to visualize the distribution and correlation of 25(OH)D and cardiometabolic indicators. Moreover, multivariate linear regressions and restricted cubic spline (RCS) functions were performed to examine the quantitative association between the serum 25(OH)D and cardiometabolic parameters. The median serum 25(OH)D level was 19.94 ng/ml in all participants, with an estimated 50.12% presenting vitamin D deficiency. Serum 25(OH)D level showed significantly modest association with cardiometabolic parameters (p less then 0.05) except for diastolic blood pressure (r=0.03, p=0.22). Multiple linear regression models showed that 25(OH)D concentration was positively associated with high-density lipoprotein cholesterol (HDL-C) and negatively associated with low-density lipoprotein cholesterol (LDL-C) and fasting serum glucose (GLU). The results of restricted cubic spline models indicated a positively linear association of 25(OH)D with HDL-C (p for overall less then 0.001, p for nonlinearity=0.191) and a negatively linear association with GLU (p for overall=0.024, p for nonlinearity=0.095). Overall, vitamin D deficiency was very common among Chinese rural population living near the 34 degrees north latitude. Besides, there were significant association between 25(OH)D concentrations and cardiometabolic biomarkers including HDL-C and GLU levels. Future longitudinal studies and randomized trials are warranted to clarify the causal relationship.
