Genital infection may be linked to miscarriage
December 04, 2002The genital infection, bacterial vaginosis, may be linked to miscarriage during the second trimester of pregnancy (13-15 weeks), concludes a study in this week’s BMJ.
Researchers at St George’s Hospital Medical School identified 1,216 pregnant women attending 32 general practices and five family planning clinics in London who were less than 10 weeks into their pregnancy.
Women were asked to provide a self administered vaginal swab and to complete a questionnaire at 16 weeks. The questionnaire asked about personal characteristics, medical history, and pregnancy outcome.
Overall, 121 women miscarried before 16 weeks and 174 had bacterial vaginosis. Those who were positive for bacterial vaginosis had a higher risk of miscarriage at 13-15 weeks compared with women who were negative for the infection.
Although bacterial vaginosis is not a strong predictor of early miscarriage, it is associated with miscarriage in the second trimester at 13-15 weeks, say the authors. The presence of chlamydial infection was too low for it to be a major risk factor for miscarriage.
The study also shows that screening for genital infections using self administered vaginal swabs is feasible in pregnant women in the community. This might be important for prevention of adverse outcomes related to infection later in pregnancy, they conclude.

A Northwestern University study has found a surprising similarity among four quite different organisms. The simplest organism, a bacterium called H. pylori, uses the same number of biochemical reactions (around 300) as yeast, the largest, most complex organism of the group, when optimizing growth.
'Zinc Zipper' Plays Key Role In Hospital-Acquired Infections
Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans.
Novel bioreactor enhances interleukin-12 production in genetically-modified tobacco plants
Interleukin-12 is a naturally occurring protein essential for the proper functioning of the human immune system.
Researchers identify cell group key to Lyme disease arthritis
A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.
Blood tests can help detect presence of necrotizing soft tissue infections
With less than half of patients with necrotizing soft tissue infections displaying the physical signs of these very serious infections, researchers have found two simple blood tests can help physicians diagnose what is commonly known as "flesh-eating bacteria," according to a study in the December issue of The American Journal of Surgery.
Vaccine and drug research aimed at ticks and mosquitoes to prevent disease transmission
Most successful vaccines and drugs rely on protecting humans or animals by blocking certain bacteria from growing in their systems. But, a new theory actually hopes to take stopping infectious diseases such as West Nile virus and Malaria to the next level by disabling insects from transmitting these viruses.
Research in twins defines shared features of the human gut microbial communities: variations linked to obesity
Trillions of microbes make their home in the gut, where they help to break down and extract energy and nutrients from the food we eat. Yet, scientists have understood little about how this distinctive mix of microbes varies from one individual to the next.
Rivers are carbon processors, not inert pipelines
Microorganisms in rivers and streams play a crucial role in the global carbon cycle that has not previously been considered.
Vitamin D found to fight placental infection
In a paper available at the online site of the journal Biology of Reproduction, a team of UCLA researchers reports for the first time that vitamin D induces immune responses in placental tissues by stimulating production of the antimicrobial protein cathelicidin.
CSHL scientists discover a new way in which epigenetic information is inherited
Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.
