Reducing Maternal Death In Bangladesh - Royal College of Obstetricians and Gynaecologists
New strategies to reduce maternal death in Bangladesh will be presented at the Royal College of Obstetricians and Gynaecologists (RCOG) South Asia Day. The conference gathers together a group of international experts to discuss ways to achieve Millennium Development Goals 4 (reduce child mortality) and 5 (improve maternal health).

Immune Genes Adapt To Parasites
Thank parasites for making some of our immune proteins into the inflammatory defenders they are today, according to a population genetics study that will appear in the June 8 issue of the Journal of Experimental Medicine (online May 25). The study, conducted by a team of researchers in Italy, also suggests that you might blame parasites for sculpting some of those genes into risk factors for intestinal disorders.

What Is A Virus? What Is A Viral Infection?
A virus (from the Latin virus meaning toxin or poison) is a microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat. Viruses are unique organisms because they cannot reproduce without a host cell. After contacting a host cell, a virus will insert genetic material into the host and take over the host"s functions. The cell, now infected, continues to reproduce, but it reproduces more viral protein and genetic material instead of its usual products. It is this process that earns viruses the classification of "parasite".

Liver Failure: Is Molecular Adsorbent Recirculating System Effective?

Since its introduction in 1993, molecular adsorbent recirculating system (MARS) albumin dialysis has been a subject of research, with the hope of effectively treating patients with acute liver failure. The impact of MARS treatment on outcome as well as clinical and laboratory variables has been investigated widely in small non-randomized studies. However, larger studies with longer follow-up time are required to determine the true usefulness of MARS treatment in different liver failure etiologies. The research led by Taru Kantola from Helsinki University Central Hospital, Finland discussed the prognostic factors for survival in patients with acute liver failure. The authors analysed the 1-year outcomes of 188 patients treated with MARS from 2001 to 2007, in an intensive care unit specializing in liver diseases. They found that the etiology of liver failure was the most important predictor of survival. In acute liver failure (ALF) of toxic etiology (e.g., paracetamol), the grade of encephalopathy before MARS treatment was a significant prognostic factor. In ALF of unknown etiology, coagulation factor 5 and liver enzyme alanine aminotransferase levels were prognostic. According to the results, the MARS treatment of a cirrhotic patient with an acute-on-chronic liver failure is not meaningful in terms of prognosis if the patient is not eligible for transplantation.
