AbstractIntroductionBehavior/Comportment/Personality (BEHAV) and Language (LANG) domains were added to the Clinical Dementia Rating (CDR®) for improving evaluation of patients with frontotemporal lobar degeneration (FTLD) (CDR® plus NACC FTLD).MethodsWe analyzed the CDR® plus NACC FTLD among participants from the baseline visit of the Advancing Research and Treatment for Frontotemporal Lobar Degeneration/Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects Consortium.ResultsThe CDR® plus NACC FTLD was able to detect early symptoms in the mildly impaired participants who were rated as CDR® sum of boxes (CDR®‐SB) = 0. The CDR®‐SB was not sensitive, particularly in participants with mild nonfluent/agrammatic primary progressive aphasia. Participants with familial and sporadic behavioral variant FTD exhibited similar CDR® plus NACC FTLD profiles except that language impairment was more frequent in participants with mild sporadic behavioral variant FTD. Adding the BEHAV and/or LANG domains to the CDR®‐SB significantly enhanced discriminatory power in differentiating among the FTLD spectrum disorders.DiscussionThe BEHAV and LANG domains enable the CDR® plus NACC FTLD to capture early symptomatology of FTLD.

Neuromonitoring is important for patients with acute brain injury. The bedside neurologic examination is standard for neurologic monitoring; however, a clinical examination may not reliably detect subtle changes in intracranial physiology. Changes found during neurologic examinations are often late signs. The assessment of multiple physiological variables in real time can provide new clinical insights into treatment decisions. No single monitoring modality is ideal for all patients. Simultaneous assessment of cerebral hemodynamics, oxygenation, and metabolism, such as in multimodal monitoring, allows an innovative approach to individualized patient care.

Patients with cirrhosis are at high risk for sepsis and sepsis-related mortality. Aggressive treatment aimed at avoidance of hypoperfusion and prompt identification and treatment of the causative organism can improve patients’ survival. Fluid administration is the first-line treatment to improve perfusion to vital organs; however, care should be taken to assess true intravascular volume status. In patients with adequate intravascular volume, vasopressors are then added to support blood pressure. Complications of cirrhosis often worsen in the setting of sepsis. Portosystemic encephalopathy, pulmonary complications, renal complications, adrenal insufficiency, malnutrition, and insufficient glucose control all must be considered and treated to support a patient with cirrhosis through sepsis. The quality of care that these patients receive ultimately influences their survival.

The most common causes of chronic cholestatic liver disease are primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Both disease processes are characterized by a destruction of intrahepatic and/or extrahepatic biliary ducts. The etiology is not entirely clear; however, there is an underlying autoimmune component contributing to both disease processes. Although PBC and PSC are often diagnosed and managed in the outpatient setting, in some instances, a patient may have jaundice, fatigue, and pruritus requiring evaluation and determination of the cholestatic cause. Patients with PSC should be monitored for evidence of cholangiocarcinoma, colon cancer, and gallbladder polyps as they are at an increased risk of malignant neoplasms. Liver transplant has the potential for improving quality of life, although disease recurrence is a risk.

Acute liver failure, also known as fulminant hepatic failure, is a rare life-threatening disease that has a high mortality rate and affects many organ systems. Causes of acute liver failure vary—it can be attributed to drugs, viruses, and other uncommon sources. Complications of liver failure can include encephalopathy, cerebral edema, sepsis, renal failure, gastrointestinal bleeding, and respiratory failure. Fortunately, with advances in critical care medicine and emergent liver transplant, mortality rates have decreased in the past decade. This article reviews acute liver failure, its manifestations in different organ systems, and its treatment.
