Peripheral arterial disease (PAD) of the upper extremity is much less frequent and aetiologically more heterogeneous than lower extremity PAD. The clinical approach to patients with upper extremity PAD must consider a range of distinctive features regarding symptoms, physical findings and diagnostic strategies. ⋯ Arteriosclerotic subclavian artery obstruction, large vessel vasculitis, thoracic outlet syndrome and secondary Raynaud's phenomenon are four pivotal causes and manifestations of upper extremity PAD. These four entities are exemplarily discussed.

Risks of thrombosis, bleeding and renal impairment are increasing with age. The efficacy and safety of the direct oral anticoagulants (DOACs) in fragile patients (age > 75 years and/or creatinine clearance levels < 50 ml/min and/or body weight below 50 kg) with indication for anticoagulation is one of the most challenging topic in cardiovascular medicine. New registry data from subgroup analyses of landmark studies and registries point towards to superiority of DOACs. This article summarizes new insights and describes pathways for anticoagulation in fragile patients.

Decisions about the initiation, continuation and termination of life-supporting treatments are a permanent challenge in intensive care units (ICUs). Decisions should be based on patient preferences and the medical indication. The medical indication is mainly the result of an assessment of the patient's prognosis and the applicable therapeutic options. ⋯ Because in many patients all these informations are not available at the time of admission, in these cases a time-limited trial is often justified to gather all this information before a decision is made. These principles of decision making can also applied to situations in which ICU-capacities are limited (e. g. COVID-19 pandemic).

Membranous nephropathy is an autoimmune disease caused in most cases by binding of circulating antibodies to antigens on podocytes. PLA2R1 and THSD7A have been identified as target antigens in 70-80 % and 2-3 % of patients, respectively. The detection of PLA2R1- and THSD7A-antibodies in the blood and staining of renal biopsies for the respective antigens allow the correct diagnosis of PLA2R1- and THSD7A-associated membranous nephropathy, respectively, in practically 100 % of cases. ⋯ Rituximab was shown to be non-inferior to ciclosporine A to induce remission of proteinuria after 12 months. After 24 months rituximab was superior to ciclosporine A for the same endpoint. Development of novel treatment strategies, focusing on disease pathogenesis, remains highly relevant for these patients.
