The globally increasing prevalence of obesity represents a key medical and socioeconomic challenge. Due to related comorbidities and complications such as arterial hypertension, diabetes mellitus, fatty liver disease, and arteriosclerosis, obesity leads to a significant statistical reduction in lifespan. Currently, bariatric surgery is the most effective approach to manage body weight and comorbidities while lifestyle intervention as basic obesity therapy and medical treatment often do not lead to sufficient and sustainable weight loss. ⋯ Apart from weight control, improvement in cardiometabolic risk factors can be achieved with this treatment. Moreover, other drugs, mostly based on incretin mono- or multiagonism, are currently developed and may open further effective treatment options for obesity and its complications in the near future. On a health political level, first steps for the development of a structured treatment program (DMP) for obesity are in progress to enable early guideline-based and structured treatment of obesity, and to prevent the obesity associated complications.

Parasites are a diverse group of pathogens; they range from unicellular protozoa (e. g. Giardia lamblia) to tapeworms that can grow several meters long. Parasites have adapted to humans over millions of years and cause a wide, colorful variety of diseases. ⋯ Nonetheless, the diagnosis is often delayed due to lack of experience of attending clinicians with parasitic infections. In this review article we give an overview of the epidemiology, transmission, diagnosis and treatment of some of the most common parasitic infections that are endemic, or regularly imported to Germany. We also discuss current and future challenges in the diagnosis, treatment and control of these pathogens.
