Pulmonary artery catheters provide important information about cardiac function, mixed venous oxygenation, and right-sided pressures and potentially provide temporary pacing ability. ⋯ The overall risk of serious complications with right heart catheter placement and manipulation is low and often outweighed by its benefits, specifically pressure monitoring and pacing.

Breathlessness is the most common symptom in individuals with pleural effusion and is often disabling. The pathophysiology of breathlessness associated with pleural effusion is complex. ⋯ Impaired hemidiaphragm function and a compensatory increase in respiratory drive to maintain ventilation appear to be an important mechanism of breathlessness associated with pleural effusion. Thoracocentesis reduces diaphragm distortion and improves its movement; these changes appear to reduce respiratory drive and associated breathlessness by improving the neuromechanical efficiency of the diaphragm.

Diabetes mellitus is the most common metabolic disease with >500 million people affected worldwide and currently 8,7 million in Germany. About 90% of diabetes cases are due to type 2 diabetes mellitus (T2D). This form of diabetes is characterized by an increased release of proinflammatory adipokines, endothelial dysfunction and hyperglycemia, among others. ⋯ People with diabetes are therefore generally considered a high-risk cardiovascular group and require special attention in the diagnosis and treatment of cardiovascular disease. Contributing factors to reduce high cardiovascular risk include a healthy lifestyle, normalization of blood pressure, optimization of blood lipid levels, and specific diabetes therapy tailored to cardiovascular risk. This review addresses the specific treatment options for reducing cardiovascular risk in patients with diabetes mellitus.

The administration of epinephrine after severe refractory hypotension, shock, or cardiac arrest restores systemic blood flow and major vessel perfusion but may worsen cerebral microvascular perfusion and oxygen delivery through vasoconstriction. The authors hypothesized that epinephrine induces significant microvascular constriction in the brain, with increased severity after repetitive dosing and in the aged brain, eventually leading to tissue hypoxia. ⋯ Intravenous application of epinephrine induced marked cerebral microvascular constriction, intravascular hemoglobin desaturation, and paradoxically, an increase in brain tissue oxygen levels, likely due to reduced transit time heterogeneity.

The progressive symptoms of Duchenne muscular dystrophy (DMD) negatively affect upper extremity skills, and this may have an effect that reduces the independence of daily life. ⋯ In our study, there was a significant relationship between the functional level of patients with DMD and upper extremity function, pain, and muscle stiffness.
