Legal Implications of Psychiatric Assessment for Medical Aid in Dying.

In recent years, several jurisdictions have passed legislation to permit medical aid in dying (MAID) worldwide, with considerable expansion in the availability of this practice. MAID has been defined as the practice of a clinician prescribing lethal drugs in response to a direct request from the patient, with a shared understanding that the patient intends to use the medication to bring about the patient's death. Wider legalization of MAID has prompted debates and legal controversies regarding the extent to which MAID should be available and its application for people experiencing mental illness as the primary indication.

Constrictive Pericarditis from an Atraumatic Hemopericardium After Systemic Thrombolysis for a Massive Pulmonary Embolism.

Constrictive pericarditis most commonly results from fibrosis and adhesions of the parietal and visceral pericardium due to long-standing inflammation. Common etiologies include idiopathic, post-surgical, radiation injury and infectious etiologies including tuberculosis. Traumatic hemopericardium is a rare cause of constrictive pericarditis but atraumatic hemopericardium causing constrictive pericarditis has not been reported in the literature to date.

The dilemma of cytomegalovirus and hepatitis B virus interaction.

Hepatitis B virus (HBV) remains a global public health problem despite the availability of effective vaccine and antiviral therapy. Cytomegalovirus (CMV), another hepatotropic virus, is also very prevalent in the general population worldwide. Both HBV and CMV can persist in the host and have potential to reactivate especially with weakened host cellular immunity.

Risk of hepatocellular carcinoma after hepatitis C virus cure.

Hepatitis C virus (HCV) is a significant cause of hepatocellular carcinoma (HCC). The direct-acting antivirals marked a new era of HCV therapy and are associated with greater than 95% cure rate. Successful treatment of chronic hepatitis C greatly reduces the risk of HCC.

Update on the applications and limitations of alpha-fetoprotein for hepatocellular carcinoma.

Alpha-fetoprotein (AFP) is an oncofetal glycoprotein that has been used as a tumor marker for hepatocellular carcinoma (HCC) in combination with ultrasound and other imaging modalities. Its utility is limited because of both low sensitivity and specificity, and discrepancies among the different methods of measurements. Moreover, its accuracy varies according to patient characteristics and the AFP cut-off values used.

A New Endemic of Concomitant Nonalcoholic Fatty Liver Disease and Chronic Hepatitis B.

Hepatitis B virus (HBV) infection remains a global public problem despite the availability of an effective vaccine. In the past decades, nonalcoholic fatty liver disease (NAFLD) has surpassed HBV as the most common cause of chronic liver disease worldwide. The prevalence of concomitant chronic hepatitis B (CHB) and NAFLD thus reaches endemic proportions in geographic regions where both conditions are common.

Clinical Presentation, Diagnosis, and Management of Air Embolism During Endoscopic Retrograde Cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive procedure that is widely used by endoscopists and has a robust therapeutic profile. It uses endoscopy and imaging for a variety of diagnostic as well as therapeutic purposes. It is used for the management of a lot of pancreaticobiliary diseases such as obstructive jaundice, obstruction related to bile ducts, pancreatic biliary tumors, and traumatic or iatrogenic damage to the bile ducts.

Adipose-derived stem cells attenuate pulmonary microvascular hyperpermeability after smoke inhalation.

Background: Pulmonary edema is a hallmark of acute respiratory distress syndrome (ARDS). Smoke inhalation causes ARDS, thus significantly increasing the mortality of burn patients. Adipose-derived stem cells (ASCs) exert potent anti-inflammatory properties.
