Heart failure (HF) patients with reduced ejection fraction (HFrEF) now more commonly die of non-cardiovascular causes than they did in the past. In patients with both HFrEF and ischemic cardiomyopathy (as the cause of HFrEF or as an accompanying condition), the effect of myocardial revascularization-i.e. percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)-on long-term outcome is unclear. ⋯ Optimal guideline-directed medical therapy is a key determinant of long-term survival in patients with HFrEF.

Adaptive radiotherapy (ART) involves the continuous adaptation of the radiation plan according to patient- and tumor-specific feedback. In online ART, the plan is optimized in real time during the treatment; in offline ART, the plan is recalculated between treatment sessions. Hybrid linear accelerators with integrated CT, MRI, or PET are required to perform online ART. ⋯ Initial studies confirm the feasibility of online ART and arouse the hope that it will enable more precise radiotherapy with less damage to surrounding structures. Phase 3 trials are needed so that the patient groups who stand to benefit most from online ART can be identified.

Age-related macular degeneration (AMD), a condition of multifactorial origin, is a major cause of irreversible vision loss in industrialized countries. The dry late stage of the disease, known as geographic atrophy (GA), is characterized by progressive loss of photoreceptor cells and retinal pigment epithelial cells in the central retina. An estimated 300 000 to 550 000 people in Germany suffer from GA. ⋯ In Europe at present, there is no approved treatment for GA due to AMD. There is thus a continuing need for preventive and rehabilitative measures such as smoking cessation, a balanced diet, and magnifying visual aids for patients in the advanced stages of the disease.

Intelligence is defined as general mental capacity, which includes the abilities to reason, solve new problems, think abstractly, and learn quickly. Genetic factors explain a considerable fraction of inter-individual differences in intelligence. For many years, research on intelligence was limited to estimating the relative importance of genetic and environmental factors, without identifying any individual causal factors. ⋯ At present, the polygenic scores generated from genome-wide association studies are primarily of scientific interest, yet they are becoming increasingly informative and valid for individual prediction. There is, therefore, a need for broad social discussion about their future use.

Open spinal dysraphism is a congenital malformation that causes major morbidity. Its consequences include sensory and motor impairment as well as bladder- and bowel dysfunction. It is often also associated with prenatal ventriculomegaly, which, in turn, necessitates postnatal treatment with a ventriculoperitoneal shunt in approximately 80% of cases. Prenatal therapy with coverage of neural tube defect can reduce the shunt rate and preserve motor function. In this review, we describe the different surgical procedures and their outcomes. ⋯ Prenatal surgery improves motor function and reduces the shunt rate but long-term outcomes beyond adolescence are still lacking. Transparent and interdisciplinary counseling is essential in prenatal communication to inform parents not only about the potential benefits of this treatment, but also about its limitations and risks.
