Thirteen patients with herpesvirus infections who were unresponsive to at least 72 h of intermittent acyclovir administration received high-dose continuous infusion. Steady-state concentrations were maintained at between 20 and 98 mumol/liter. Of 12 patients who had continuous infusion for greater than 5 days, 7 (58%) resolved their infections, as determined by clinical and virologic parameters, suggesting that continuous infusion may succeed in some patients who do not respond to conventional therapy.

In this editorial we examine the article by Wu published in the . Surgical resection for peritoneal metastases from colorectal cancer (CRC) has been gradually accepted in the medical oncology community. A randomized trial (PRODIGE 7) on cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) failed to prove any benefit of oxaliplatin in the overall survival of patients with peritoneal metastases from colorectal origin.

Purpose: Resting beat-to-beat blood pressure variability is a strong predictor of cardiovascular events and mortality. However, its underlying mechanisms remain incompletely understood. Given that the sympathetic nervous system plays a pivotal role in cardiovascular regulation, we hypothesized that alpha-1 adrenergic receptors (the main sympathetic receptor controlling peripheral vasoconstriction) may contribute to resting beat-to-beat blood pressure variability.

Background: Disorders of the coagulation pathway are triggered in patients with severe burn and inhalation injuries in the early stages. There are multiple early coagulation indices identified to correlate with adverse outcomes.
Method: A retrospective analysis of patients with severe burn and inhalation injuries from 12 centers in mainland China was performed to identify early changed coagulation indices with predictive value associated with four major 28-day adverse outcomes (death, anticoagulation, mechanical ventilation, continuous renal replacement therapy) by logistic regression.

An increasing number of procedures over the past two decades for aortic stenosis (AS) reflects the combination of an aging population and less invasive transcatheter options. As a result, the hemodynamics of the aortic valve (AV) have gained renewed interest to understand its behavior and to optimize patient selection. We studied the hemodynamic relationship between pressure loss (ΔP) and transvalvular flow (Q) of the normal AV as well as the impact of a variable supravalvular stenosis.

Nitrocellulose (NC)-based propellants have played a pivotal role in the development of energetic materials for both military and civilian applications. This review offers a comprehensive exploration of NC-based propellants, tracing their evolution from their historical origins as smokeless gunpowder to modern advancements. It discusses the chemical composition and classifications of NC propellants, along with continuous efforts to refine smokeless powder formulations through studies on smoke formation, residues, and additives.
