The circadian clock regulates multiple aspects of human physiology including immunity. People have a circadian preference termed chronotype. Those with an evening preference may be better suited to shift work, but also carry higher risk of adverse health.

Intercellular transfer of damaged mitochondria is a recently identified strategy broadly used to improve cellular health and viability. Here, we investigate mitochondrial homeostasis in the vertebrate cone photoreceptor, the specialized neuron that initiates our daytime and color vision.
View Article and Find Full Text PDFImportance: Photoaggravated atopic dermatitis (PAD) is estimated to affect 1.4% to 16% of patients with AD but remains poorly characterized with limited published data.
Objective: To provide detailed clinical and photobiological characterization of PAD.
Cone photoreceptors in the retina are exposed to intense daylight and have higher energy demands in darkness. Cones produce energy using a large cluster of mitochondria. Mitochondria are susceptible to oxidative damage, and healthy mitochondrial populations are maintained by regular turnover.

They cause a range of distressing symptoms including pain and burn, and can make the skin blister, flake and scar. The conditions themselves and the need for patients to avoid and protect themselves from sunlight may affect quality of life and psychological health.
View Article and Find Full Text PDFBackground: The photodermatoses affect large proportions of the population but their impact on quality of life (QoL) and psychological health has not been reviewed. Several tools are available to evaluate QoL and psychological impacts.
Objectives: To systematically review current literature to identify tools used to assess QoL and psychological impacts in patients with photodermatoses, and to summarize the reported findings.
Acute liver failure (ALF) is a rare condition with fatal outcome. Characteristic is rapid onset of liver damage without preexisting liver diseases, including hepatic encephalopathy and coagulopathy. Early and correct diagnosis is essential for further management of patients, since diagnosis impacts therapy choice.
View Article and Find Full Text PDFLactate levels and lactate clearance are known predictors of outcome in critically ill patients in the intensive care unit (ICU). The prognostic value of lactate is not well established in liver cirrhosis and acute-on-chronic liver failure (ACLF). The aim of this study was to assess the prognostic value of lactate levels and clearance in critically ill patients with cirrhosis.
View Article and Find Full Text PDFBackground: Acid-base disturbances are frequently observed in critically ill patients at the intensive care unit. To our knowledge, the acid-base profile of patients with acute-on-chronic liver failure (ACLF) has not been evaluated and compared to critically ill patients without acute or chronic liver disease.
Results: One hundred and seventy-eight critically ill patients with liver cirrhosis were compared to 178 matched controls in this post hoc analysis of prospectively collected data.
Background: Organ failure increases mortality in patients with liver cirrhosis. Data about resuscitated cardiac arrest patients with liver cirrhosis are missing. This study aims to assess aetiology, survival and functional outcome in patients after successful cardiopulmonary resuscitation (CPR) with and without liver cirrhosis.

While plant cells secrete EVs, they have only recently been isolated and questions regarding their biogenesis, release, uptake and function remain unanswered. Here, we present a detailed protocol for isolating EVs from the apoplastic wash of leaves.
View Article and Find Full Text PDFBackground: Jaundice and cholestatic hepatic dysfunction are frequent findings in critically ill patients associated with increased mortality. Cholestasis in critically ill patients is closely associated with stimulation of pro-inflammatory cytokines resulting in impaired bile secretion and subsequent accumulation of bile acids. Aim of this study was to evaluate the clinical role of circulating bile acids in critically ill patients.
View Article and Find Full Text PDFHepatopulmonary syndrome (HPS) occurs in 20 - 30 % of patients with cirrhosis and is associated with increased mortality. Cholestasis and accumulation of bile acids (BAs) play a major role in chronic liver disease. We aimed to evaluate the clinical role of serum BAs in patients with HPS.
View Article and Find Full Text PDFBackground & Aims: The risk of hepatocellular carcinoma (HCC) is reduced but not eradicated among patients with hepatitis C virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of cirrhosis-related complications in this specific group of patients.
Methods: Data from previously reported Western cohort studies including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level.
Background: Treatment of chronic hepatitis C virus (HCV) infection was revolutionized within the last years. Interferon free antiviral regimens are not accessible without limitations. Combination of peginterferon/ribavirin with first generation direct acting antivirals is less effective and associated with serious adverse events.
View Article and Find Full Text PDFBackground & Aims: Retention of bile acids (BAs) plays a central role in hepatic damage and disturbed BA signalling in liver disease. However, there is lack of data regarding the association of BAs with clinical complications, acute decompensation (AD) and acute-on-chronic liver failure (ACLF). Thus, we aimed to evaluate the impact of circulating serum BAs for complications in patients with cirrhosis.
View Article and Find Full Text PDFBackground: Hypoxic hepatitis (HH) is a frequent and potentially life-threatening event typically occurring in critically ill patients as a consequence of hemodynamic impairment. While acute kidney injury (AKI) has been well described in patients with acute liver failure, incidence and outcome of AKI accompanying HH are unclear. The aim of this study was to assess incidence, clinical implications and outcome of AKI and renal replacement therapy (RRT) in critically ill patients with HH.

The typical laboratory pattern mimics disseminated intravascular coagulation (DIC). The aim of this study was to assess the impact of routine coagulation parameters in critically ill cirrhosis patients with regard to new onset of major bleeding and outcome.

Hypoxic/ischemic hepatitis (HH) is a diffuse hepatic damage associated with high morbidity and mortality. Indocyanine green plasma disappearance rate (ICG-PDR) is an effective tool assessing liver function in acute and chronic hepatic diseases.

Interactions between the hepatic portal and cardiovascular systems are frequently found in patients with liver disease. Cirrhotic cardiomyopathy (CCMP) is defined as reduced cardiac function in patients with liver cirrhosis in the absence of other known causes of cardiac disease. The typical hyperdynamic circulatory state by means of increased cardiac output and reduced systemic vascular resistance may mask left ventricular failure.
