Extracorporeal carbon dioxide removal (ECCO2R) uses mechanical systems to treat hypercapnic respiratory failure. Its utility has been investigated in acute respiratory distress syndrome (ARDS), acute exacerbations of chronic obstructive pulmonary disease (COPD), and status asthmaticus, and as a bridge to lung transplant. In this review, we discuss how it works, why it should help, and current evidence supporting its use.

Type 1 diabetes is a disease resulting from autoimmune destruction of the insulin-producing beta cells in the pancreas. When type 1 diabetes develops into severe secondary complications, in particular end-stage nephropathy, or life-threatening severe hypoglycemia, the best therapeutic approach is pancreas transplantation, or more recently transplantation of the pancreatic islets of Langerhans. Islet transplantation is a cell therapy procedure, that is minimally invasive and has a low morbidity, but does not display the same rate of functional success as the more invasive pancreas transplantation because of suboptimal engraftment and survival. ⋯ A successful bioartificial pancreas would address the issues of engraftment, survival and rejection. Inclusion of unlimited sources of insulin-producing cells, such as xenogeneic porcine islets or stem cell-derived beta cells would further solve the problem of organ shortage. This article reviews the current status of clinical islet transplantation, the strategies aiming at developing a bioartificial pancreas, the clinical trials conducted in the field and the perspectives for further progress.

Nonalcoholic fatty liver disease (NAFLD) affects approximately 37% of US adults. The progression from nonalcoholic fatty liver with no inflammation to steatohepatitis with inflammation and progressive fibrosis is associated with substantial morbidity and mortality. The epidemic of NAFLD requires that primary care providers recognize at-risk patients and screen them. The authors review identifying individuals at risk, treatment options founded on lifestyle modification, and when to consider referring patients to a hepatologist.

Dementia with Lewy bodies (DLBs) is a common cause of dementia but has higher mortality than Alzheimer's disease (AD). The reasons for this are unclear, but antidementia drugs (including acetylcholinesterase inhibitors [AChEIs] and memantine) symptomatically benefit people with DLB and might improve outcomes. We investigated whether AChEIs and/or memantine were associated with reduced hospital admissions and mortality. ⋯ In this study, we observed that use of AChEIs with or without memantine in DLB was associated with shorter duration of hospital admissions and decreased risk of mortality. Although our study was naturalistic, it supports further the use of AChEIs in DLB.

ReviewA Narrative Review of the Pathophysiology and Treatment of Hypertrophic Cardiomyopathy.
Hypertrophic cardiomyopathy (HCM) is a genetic autosomal dominant disorder of the heart muscle that is characterized by left ventricular hypertrophy and sudden cardiac death. It is the most common inherited cardiac disease. HCM is defined by sarcomeric mutations that result in fibrosis of the heart, affecting contraction. ⋯ The goals of pharmacological therapy as well as nonpharmacological therapy are to alleviate the symptoms and to prevent sudden cardiac death. Anatomical defects are treated primarily by surgical intervention, whereas other issues such as hypercontractility are treated with pharmacotherapy. In this article, we review the pathophysiology and treatment options for HCM.
