New research published in the European Heart Journal has found that long-term antibiotic use in women can increase their risk of heart attack or stroke. The research involved 36,429 women from The Nurses’ Health Study.

 

The Nurses’ Health Study has been running in the US since 1976. The researchers run some of the most comprehensive investigations into the risk factors associated with chronic disease in women.

After 20 years of dedicated research, scientists have cracked the chemical code of an incredibly complex 'anti-tumor antibiotic' known to be highly effective against cancer cells as well as drug-resistant bacteria, and have reproduced it synthetically in the lab for the first time.

This major breakthrough and world-first could hail a new era in the design and production of new antibiotics and anticancer agents.

Curcumin is widely used to impart color and flavor to food, but scientists have discovered that this yellow powder derived from the roots of the turmeric plant (Curcuma longa) can also help prevent or combat stomach cancer.

The study by researchers at the Federal University of São Paulo (UNIFESP) and the Federal University of Pará (UFPA) in Brazil identified possible therapeutic effects of this pigment and of other bioactive compounds found in food on stomach cancer, the third and fifth most frequent type of cancer among Brazilian men and women, respectively.

To explain a person's actions in the present, it sometimes helps to understand their past, including where they come from and how they were raised. This is also true of tumors. Delving into a tumor's cellular lineage, a Ludwig Cancer Research study shows, can reveal weaknesses to target for customized therapies.

The findings, detailed in the April 24 issue of the journal Nature, also illustrate how knowledge of the biochemistry and microenvironment of the tissue from which a tumor arises can help predict the genetic alterations its cancer cells are likely to undergo.

What are the most common disease-causing pathogens encountered by humans? Where do these pathogens reside in the environment?

The biggest disease-causing pathogens  are cold and flu, which are spread through respiratory secretions when someone sneezes, and contaminated environments. The questions for contaminated environments are; how do we keep the surface clean? And, how do we prevent individuals from touching a surface and then their faces including their mouths?

 

A DNA test method called polymerase chain reaction (PCR) allowed New York City health officials to identify the source of a Legionnaires' disease outbreak within hours of specimen collection and should be considered in all Legionnaires' outbreak investigations, researchers say in the April issue of the Journal of Environmental Health.

Eating high fiber foods may reduce the effects of stress on our gut and behavior, according to new research published in The Journal of Physiology.

Stress is a significant health concern and can cause major changes in the gut and in the brain, which can cause changes in behavior. In recent years there has been growing interest in the link between gut bacteria and stress-related disorders including anxiety, depression and irritable bowel syndrome.

A preliminary study published in the August issue of Mayo Clinic Proceedingssuggests that, for some people, specific activities of gut bacteria may be responsible for their inability to lose weight, despite adherence to strict diet and exercise regimens.

All healthcare facilities and hospitals need to step up their hand washing techniques as well as use of alcohol based hand sanitizers after reports of emergence of hospital super bacteria that are becoming more tolerant to alcohol.

Nutrition advisers agree about red meat being rich sources of iron, zinc, omega 3 fatty acids, vitamins especially B12 and suggest that these are good for the health of heart as well as the brain. However recent propaganda says too much red meat and processed meat can be harmful for health including raising the risk for certain cancers.

Most of the general population thus remains confused when choosing red meat about which one to take and in what quantities.
