Up to 8% of pregnant women suffer from preeclampsia (PE), a deadly disease characterized by high blood pressure (BP), blood vessel damage, called endotheliosis (vascular endothelial swelling with narrowing of capillary lumen), and high levels of protein in the urine. PE is often associated with premature delivery, which is a risk factor of cardiovascular and metabolic diseases among the offspring. Accordingly, establishing drug treatments of PE is in immediate needs. Currently, many of anti-hypertensive drugs cause malformation of the fetuses and are contraindicated for pregnant women...

Smouldering inflammation, thrombocytosis, and platelet hyper-reactivity are linked to malignancy. The relationships between preoperative diagnostic blood morphology parameters and cancer have been the focus of much interest, because some of these parameters are correlated with advanced cancer stages and poor patient survival rates. This study aimed to perform an observational, retrospective analysis of the intradiversity of blood platelet parameters in patients with different International Federation of Gynaecology and Obstetrics (FIGO) stages and different histological types of epithelial ovarian carcinomas (EOC), and also an analysis of the overall survival rate...

Tigecycline, a glycylcycline-derived antibacterial that has been approved for the treatment of various infections, is widely used for multi-drug resistant bacteria. Coagulopathy is an uncommon side effect during tigecycline treatment and is easily overlooked when it occurs. We reported the effect of tigecycline (50 mg every twelve hours) treatment in an 87-year-old man, with Gram negative bacillary pneumonia and respiratory failure. After 7 days of tigecycline treatment, a significant drop of hemoglobin and patchy ecchymosis over both thighs were suddenly observed despite stable clinical condition...

In diabetic patients undergoing surgery, we recommend assessing glycaemic control preoperatively by assessing glycated haemoglobin (HbA1c) levels and recent capillary blood sugar (glucose) levels, and to adjust any treatments accordingly before surgery, paying particular attention to specific complications of diabetes. Gastroparesis creates a risk of stasis and aspiration of gastric content at induction of anaesthesia requiring the use of a rapid sequence induction technique. Cardiac involvement can be divided into several types...

BACKGROUND: Many studies have focused on the challenges of small molecule uptake across the blood-brain barrier, whereas few in-depth studies have assessed the challenges with the uptake of antibodies into the central nervous system (CNS). In drug development, cerebrospinal fluid (CSF) sampling is routinely used as a surrogate for assessing CNS drug exposure and biomarker levels. In this report, we have studied the kinetic correlation between CSF and serum drug concentration-time profiles for five humanized monoclonal antibodies in rats and cynomolgus monkeys and analyzed factors that affect their CSF exposure...

Exposure of healthcare workers to anticancer drugs requires the combined action of environmental and biological monitoring to assess the effective level of exposure to these chemicals, to improve awareness and to avoid adverse health effects on this category of workers. Cancer chemotherapeutic drugs show different mechanisms of action due to diverse chemical structures; consequently, they differ in hydrophobicity, pharmacokinetics and pharmacodynamics. Therefore, the appearance, accumulation and elimination of each of these molecules in body fluids and tissues might be extremely variable; this prompts the need for a rapid and versatile analytical protocol for the biological monitoring of possible exposure of workers involved in the manipulation, administration and disposal of cancer chemotherapeutic drugs...
