OBJECTIVE: To analyze the effects of motor intervention on the neuropsychiatric symptoms of Alzheimer's disease and on the caregivers' burden. DESIGN: This is a controlled trial evaluating the effects of a motor intervention program on the neuropsychiatric symptoms. SETTING: The intervention was performed on community patients from two university centers specializing in physical exercise for the elderly. SUBJECTS: Patients with Alzheimer's disease were divided into two groups: sixteen received the motor intervention and sixteen controls (five controls were excluded because of clinical intercurrences). INTERVENTIONS: Aerobic exercises (flexibility, strength, and agility) and functional balance exercises were conducted over six months for 60 minutes three times per week. MAIN MEASURES: Psychopathological features of patients were evaluated with the Neuropsychiatric Inventory and Cornell Scale for Depression in Dementia. Caregivers were evaluated using the Neuropsychiatric Inventory-Distress and Burden Interview. A two-way analysis of variance (ANOVA) was applied to observe interactions (pre- vs. postintervention; participants vs. controls). RESULTS: Patients from the intervention presented a significant reduction in neuropsychiatric conditions when compared to controls (Neuropsychiatric Inventory: F511.12; p=0.01; Cornell Depression scale: F511.97; p=0.01). The burden and stress of caregivers responsible for patients who participated in the intervention significantly decreased when compared to caregivers responsible for controls (Neuropsychiatric Inventory-Distress: F: 9.37; p=0.01; Burden Interview: F: 11.28; p=0.01). CONCLUSIONS: Aerobic exercise was associated with a reduction in the neuropsychiatric symptoms and contributed to attenuate the caregivers' burden. However, the researchers were not blinded to the patient's intervention status, which constitutes an important limitation of this study. © 2011 Clinics. Source

The peripheral arterial vasodilation hypothesis has been most influential in the field of cirrhosis and its complications. It has given rise to hundreds of pathophysiological studies in experimental and human cirrhosis and is the theoretical basis of life-saving treatments. It is undisputed that splanchnic arterial vasodilation contributes to portal hypertension and is the basis for manifestations such as ascites and hepatorenal syndrome, but the body of research generated by the hypothesis has revealed gaps in the original pathophysiological interpretation of these complications. The expansion of our knowledge on the mechanisms regulating vascular tone, inflammation and the host-microbiota interaction require a broader approach to advanced cirrhosis encompassing the whole spectrum of its manifestations. Indeed, multiorgan dysfunction and failure likely result from a complex interplay where the systemic spread of bacterial products represents the primary event. The consequent activation of the host innate immune response triggers endothelial molecular mechanisms responsible for arterial vasodilation, and also jeopardizes organ integrity with a storm of pro-inflammatory cytokines and reactive oxygen and nitrogen species. Thus, the picture of advanced cirrhosis could be seen as the result of an inflammatory syndrome in contradiction with a simple hemodynamic disturbance. © 2015 European Association for the Study of the Liver.

Although systemic inflammation is a hallmark of acute-on-chronic liver failure (ACLF), its role in the development of this syndrome is poorly understood. Here the author first summarizes the general principles of the inflammatory response. Inflammation can be triggered by exogenous or endogenous inducers. Important exogenous inducers include bacterial products such as pathogen-associated molecular patterns (PAMPs) and virulence factors. Pathogen-associated molecular patterns elicit inflammation through structural feature recognition (using innate pattern-recognition receptors [PRRs]), whereas virulence factors generally trigger inflammation via functional feature recognition. Endogenous inducers are called danger-associated molecular patterns (DAMPs) and include molecules released by necrotic cells and products of extracellular matrix breakdown. Danger-associated molecular patterns use different PRRs. The purpose of the inflammatory response may differ according to the type of stimulus: The aim of infection-induced inflammation is to decrease pathogen burden, whereas the DAMP-induced inflammation aims to promote tissue repair. An excessive inflammatory response can induce collateral tissue damage (a process called immunopathology). However immunopathology may not be the only mechanism of tissue damage; for example, organ failure can develop because of failed disease tolerance. In this review, the author also discusses how general principles of the inflammatory response can help us to understand the development of ACLF in different contexts: bacterial infection, severe alcoholic hepatitis, and cases in which there is no identifiable trigger. © 2016 by Thieme Medical Publishers, Inc.

Patients with cirrhosis are prone to developing bacterial infections. Moreover, bacterial infection is the most common identifiable trigger of acute-on-chronic liver failure (ACLF), which is characterized by organ failures and a high risk of death. There is evidence of an excessive immune response of the host as a major mechanism leading to the development of organ failures in patients with cirrhosis. However, a role for direct tissue damage caused by bacterial toxins and virulence factors cannot be excluded. Failed tolerance mechanisms may also contribute to organ failures, although the involved mechanisms are unclear. A proportion of patients with infection-related ACLF have a prolonged stay in the intensive care unit. These patients have immune suppression, increased risk of superinfection and poor outcome. Immune suppression might be a consequence of the first infection episode that has led patients to be admitted to hospital. © 2015 S. Karger AG, Basel. Source

A proportion of patients hospitalized for an acute complication of cirrhosis are at high risk of short-term death. The term Acute-on-Chronic Liver Failure (ACLF) is used to characterize these patients. Until recently there was no evidence-based definition of ACLF. In 2013 a definition has been proposed based on results of a large prospective observational European study, called "European Association for the Study of the Liver (EASL)-Chronic Liver Failure (CLIF) Consortium Acute-on-Chronic Liver Failure in Cirrhosis (CANONIC)" study. Results of this study led to elaborate new concepts about ACLF. First, it was found that ACLF is a syndrome that is distinct from mere decompensated cirrhosis. It was also shown that ACLF is a dynamic syndrome which can improve or conversely worsen. Patients who worsen die rapidly from multiorgan failures. The CANONIC study also found that identifiable precipitating events (e.g., bacterial infection, active alcoholism) are found in only 50% of cases of ACLF indicating that these events are dispensable for defining ACLF. In addition precipitating events may be initiators of ACLF but do not drive the outcome. An important concept derived from the CANONIC study is that ACLF is associated with systemic inflammation even in patients who do not have identifiable precipitating events. Finally it was found that ACLF may develop in patients without prior episodes of decompensation or in those with recent decompensation (<3 months). Moreover these patients with "early" ACLF were more severe than patients who developed ACLF after a long of history of decompensated cirrhosis. © 2014 INASL. Source
