Human herpesvirus 6 (HHV-6) is a double-stranded DNA virus part of the Herpesviridae family that colonizes nearly 100% of the human population. The virus is known to be the etiologic agent of roseola infantum, a self-limited disease in childhood and reactivation of the virus later in life is linked to potentially severe manifestations, including encephalitis, in immunosuppressed patients. It is rare in immunocompetent patients, but there have been several reports of encephalitis due to HHV-6 reactivation. We describe here a case of altered mental status and multi-organ failure in an immunocompetent woman, whose cerebrospinal fluid (CSF) was positive for HHV-6 DNA by polymerase chain reaction (PCR).

The majority of drugs are typically orally administered. The journey from drug discovery to approval is often long and expensive, involving multiple stages. A major challenge in the drug development process is drug-induced liver injury (DILI), a condition that affects the liver, the organ responsible for metabolizing most drugs.

This study aimed to investigate whether lymphocyte-C-reactive protein ratio (LCR) upon admission can predict disease progression and intensive care unit (ICU) admission in adult patients with diabetic ketoacidosis (DKA). A single-center retrospective study was conducted, including adult DKA patients admitted to the First Affiliated Hospital of Harbin Medical University between March 2018 and March 2023. Multiple demographic and clinical data were collected from the medical records upon admission and during hospitalization.

Acute Heart Failure (AHF) is a leading cause of death and represents the most frequent cause of unplanned hospital admission in patients older than 65 years. Since the past decade, several randomized clinical trials have highlighted the importance and pivotal role of certain therapeutics, including decongestion by the combination of loop diuretics, the need for rapid goal-directed medical therapies implementation before discharge, risk stratification, and early follow-up after discharge therapies. Cardiogenic shock, defined as sustained hypotension with tissue hypoperfusion due to low cardiac output and congestion, is the most severe form of AHF and mainly occurs after acute myocardial infarction, which can progress to multiple organ failure.

Objective: It is controversial whether rapid lowering of triglyceride (TG) levels is associated with clinical benefits in patients with hypertriglyceridaemia-associated acute pancreatitis (HTG-AP). In particular, patients with different severity of disease may respond differently to TG-lowering therapy. In this study, we aimed to explore the association between rapid decline in serum TG levels and organ failure in patients with different severities of HTG-AP.
