Increasing interest in diverticular disease by the scientific community in the last 10-15 years has resulted in an increased number of publications. Among other things, nonevidence-based therapeutic paradigms were tested in randomized, controlled therapy studies. The importance of surgery in the therapy of diverticulitis has diminished in recent years; in particular, it has no role in the treatment of diverticulitis types 1a, 1b, and 2a according to the Classification of Diverticular Disease (CDD) treated successfully by conservative means. ⋯ Over 90% of patients with type 1a/1b diverticulitis can be safely treated according to current data without the use of antibiotics. It is possible that type 2a diverticulitis will also be successfully treated without antibiotics in the future. Substances such as rifaximin, mesalazine, or probiotics, which were tested above all in patients with chronic recurrent forms (CDD type 3a/3b), have not yet been established.

Indications for anticoagulation are thromboembolic events, prosthetic heart valves, and atrial fibrillation with a corresponding risk score. Clinical trials have excluded patients with advanced chronic kidney disease and these data cannot be always generalized to patients with chronic kidney disease. Non-vitamin K antagonist oral anticoagulants (NOACs) are mostly not recommended or are contraindicated in advanced stages of chronic kidney disease. Observational studies have shown that dialysis patients with atrial fibrillation do not profit from coumarin anticoagulants; prospective studies are lacking.

The human intestinal microbiome has important metabolic and immunological functions for the host and is part of the defense against pathogens in the gastrointestinal tract. Antibiotics, probiotics, dietary measures, such as prebiotics, and the relatively newly established method of fecal microbiota transplantation (FMT, also known as fecal microbiome transfer) all influence the intestinal microbiome. The FMT procedure comprises the transmission of fecal microorganisms from a healthy donor into the gastrointestinal tract of a patient. ⋯ A careful donor selection is necessary. The implementation of FMT in Germany is subject to the Medicines Act (Arzneimittelgesetz, AMG) with a duty of disclosure and personal implementation by the attending physician. By documentation in a central register long-term effects and side effects of FMT have to be evaluated.

Type 2 diabetes mellitus is a growing chronic disease with a complex pathophysiology and multiple therapeutic options. Clinical prognosis is determined by multimorbidity and cardiovascular complications. For example, the prognosis of patients with diabetes hospitalized for heart failure is very poor with up to 50% mortality rate over the 3 years thereafter. ⋯ In this context, it is interesting to note that new cardiovascular outcome trials with a so-called safety design have shown that the GLP-1 receptor agonist liraglutide and the SGLT-2 inhibitor empagliflozin can reduce cardiovascular event rates. In addition, empagliflozin has significantly reduced the rate of hospitalization for heart failure. The latter has been included in the recent guidelines on heart failure by the European Society of Cardiology.

Hypercholesterolemias are known risk factors for cardiovascular diseases. Although statins have reduced the cardiovascular morbidity and mortality and further therapeutic measures are available, treatment goals are often not achieved. In cases of very high levels of low-density lipoprotein (LDL) cholesterol or of intolerability, the established therapies are often not sufficiently effective or cannot be used in adequate doses. For these high-risk patients further treatment options are required. ⋯ The body of evidence is rapidly increasing thereby facilitating the decision making when PCSK9 inhibitors could be used. The PCSK9 inhibitors will considerably improve the options for optimal treatment of high-risk patients.
