Cervical cancer mortality rates underestimated?

Cervical cancer is considered to be rather treatable, and somewhat uncommon, but a new analysis believes the risk of dying from cervical cancer is higher than previously thought.

Less surprisingly, there are still racial differences in mortality. 

Anemia in India solved with iron-fortified bars

Human beings can be mysterious; some want raw milk though it is straight from a bacteria-laden cow udder (if you have ever milked a cow, you know what we are talking about) but is untouched by science, while others swear by supplements.

How to reduce peanut allergy risk

Ironically, there are more peanut allergies because hyperactive parents have read too many stories about peanut allergies and are convinced their child will go into anaphylactic shock if someone in the back of the airplane eats one. They go to an allergist - and they are certain to find a sensitivity to something - and concerned parents conflate a peanut sensitivity with being allergic.  But a positive test alone is a poor indicator of allergy.  

Improving fecal microbiota transplantation

A placebo-controlled trial may provide a strategy for improving fecal microbiota transplantation (FMT) for patients with recurrent Clostridium difficile infection. The study identified microorganisms that are key for cure with fecal microbiota transplantation.

Never-smoking women have high prevalence of COPD

African-American women who have never smoked have a high prevalence of Chronic Obstructive Pulmonary Disease (COPD) -7 percent versus 5.2% of European-American womenand 2.9% of never-smoking European-American men.

Researchers are scrambling to explain it because COPD is the third leading cause of death in the USA and smoking is considered the biggest risk factor for the disease. Yet 25 percent of Americans with COPD have never smoked.

Smoking intensity in coronary heart disease risk

Smoking causes increased relative risks for coronary heart disease, so the number of cigarettes must also. If you smoke twice as many cigarettes, your risk should be twice as high, right? 

A new study instead says it's time spent smoking, not quantity of cigarettes. 

Cellular switch to turn off asthma attacks

Using human immune cells, researchers report they have identified a critical cellular "off" switch for the inflammatory immune response that contributes to lung-constricting asthma attacks. The switch, they say, is composed of regulatory proteins that control an immune signaling pathway in cells.

Saturated fat is bad for you again, finds weak observational study

Data from 73,147 women involved in the Nurses' Health Study between 1984 and 2012, and 42,635 men who were in the Health Professionals Follow-up Study between 1986 and 2010, correlates saturated fats in red meat, dairy, butter, lard, and palm oil, may increase the risk of coronary heart disease.

Significantly more radioactivity in infant formula than reported

Based on measurements of radioactivity in samples of infant formula manufactured and sold around the world, researchers estimate that infants 1 year of age or younger who consume these formulas would ingest a significantly higher radioactivity dose than reported levels, but lower than internationally recommended limits. The researchers report the radioactivity levels for each brand of formula in an article published in Environmental Engineering Science, http://online.liebertpub.com/doi/full/10.1089/ees.2015.0114.

Sexual activity causes immune system changes that increase chances of conception

Sexual activity causes immune system changes that increase chances of conception

Research from Indiana University has found that sexual activity triggers physiological changes in the body that increase a woman's chances of getting pregnant, even outside the window of ovulation.

The results could eventually influence recommendations regarding how often to engage in sexual intercourse for couples trying to get pregnant. It could also potentially impact treatment for people with autoimmune disorders.
