Eating red meat linked to kidney failure risk

By Shereen Lehman (Reuters Health) - Red meat may take a toll on the kidneys that increases risk for kidney disease and eventually kidney failure, a large study suggests. The authors also found that replacing some red meat in the diet with other types of protein – whether chicken, fish, eggs or vegetable sources – might dramatically reduce that risk. “There is an increase in numbers of individuals developing chronic kidney disease worldwide, and many progress to end-stage renal disease, which requires dialysis or a kidney transplant,” Woon-Puay Koh told Reuters Health by email.

Fosun to buy KKR-backed Indian drugmaker for up to $1.3 billion

A man walks in front of the headquarters of Shanghai Fosun Pharmaceutical Group in ShanghaiHONG KONG/MUMBAI (Reuters) - Shanghai Fosun Pharmaceutical Group Co Ltd has agreed to buy an 86 percent stake in Gland Pharma - backed by KKR & Co LP - for up to $1.3 billion, the largest acquisition of an Indian company from abroad this year. The deal, announced by the two sides on Thursday, is the first major move by the Fosun group since Guo Guangchang, founder of flagship holding firm Fosun International Ltd and one of China's best-known entrepreneurs, briefly went missing late last year. The acquisition, subject to regulatory approvals, would also underscore a positive outlook for drugmakers in India, which is a major global supplier and counts the United States as its largest export market, helped by lower manufacturing and labor costs.

New study on Chinese seniors shows vitamin D could prevent cognitive decline

New study on Chinese seniors shows vitamin D could prevent cognitive declineNew research on vitamin D has found that low levels of the vitamin are associated with an increased risk of cognitive decline in Chinese seniors. It has also been found to have a significant effect on cognitive health, with previous studies in Europe and North America showing that a low level of vitamin D is linked with an increased risk of cognitive decline. This new study, conducted by Duke-NUS Medical School (Duke-NUS) and Duke University, is now the first large-scale prospective study in Asia to look at an association between vitamin D levels and the risk of cognitive decline and impairment in the Chinese elderly.

Study finds cosmic rays increased heart risks among Apollo astronauts

Astronaut Neil A. Armstrong, Apollo 11 commander, is pictured inside the Lunar Module (LM) while the LM rested on the lunar surface during the Apollo 11 mission in this NASA handout photoBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Apollo astronauts who ventured to the moon are at five times greater risk of dying from heart disease than shuttle astronauts, U.S. researchers said on Thursday, citing the dangers of cosmic radiation beyond the Earth's magnetic field. The study by researchers at Florida State University and NASA found that three Apollo astronauts, including Neil Armstrong, the first person to walk on the moon, or 43 percent of those studied, died from cardiovascular disease, a finding with implications for future human travel beyond Earth. The research, published in the journal Scientific Reports, was the first to look at the mortality of Apollo astronauts, the only people so far to travel beyond a few hundred miles (km) of Earth.

Quest for new antibiotics gets right up your nose

Quest for new antibiotics gets right up your noseBiologists on the hunt for new medicines to fight a growing epidemic of drug resistance said Wednesday they found an antibiotic in an unexpected place -- the human nose. The promising compound is produced by a nose-dwelling bacterium, and is able to kill a disease-causing, antibiotic-resistant superbug, they reported. "It was completely unexpected to find a human-associated bacterium to produce a real antibiotic," said study co-author Andreas Peschel of the University of Tubingen in Germany.

Later menstruation and menopause linked to longevity

Women who begin menstruating after the age of 12 and enter menopause after the age of 50 are more likely to live to 90.According to new American research, women who begin menstruating after the age of 12 and enter menopause after the age of 50 are more likely to live to 90 years old. After studying 16,000 women for 21 years, the scientists' findings -- published in the journal Menopause -- show that women who started menstruating after the age of 12 and entered menopause after the age of 50 were more likely to live to 90, especially those with more than 40 reproductive years between their first and final menstrual periods. Note that the average age of menopause is 51, but women can enter this phase of life between the ages of 40 and 55.

Breast milk protein protects preterm babies from infection, study finds

The protein occurs naturally in breast milk and helps the body absorb iron from food.New research from scientists at an American university reveals that giving premature babies a synthetic form of lactoferrin -- a protein naturally present in breast milk -- can eliminate staphylococcus epidermidis, a staph infection that can be deadly in infants born preterm. Researchers from the University of Missouri, Columbia, USA, have identified the role of a protein, called lactoferrin, that protects preterm babies from a type of staph infection. This antimicrobial protein occurs naturally in breast milk and helps the body absorb iron from food.

Too much light at night, too little in the morning tied to obesity risk

By Kathryn Doyle (Reuters Health) - Older people exposed to high lighting in the evening, and low light in the morning are more likely to gain weight, and the opposite light exposures may encourage weight loss, Japanese researchers say. Over two years, lighting exposure was tied to abdominal weight gain regardless of other factors like calorie intake, exercise and what time people went to sleep or woke up, the study found. “Our results are reasonable because human beings have evolved under the lighting condition of daytime high and nighttime low light intensity,” said lead author Dr. Kenji Obayashi of Nara Medical University School of Medicine.

Comparison of commercial and homemade infant meals finds flaws in each

By Madeline Kennedy (Reuters Health) - Parents making home-cooked meals often provide babies with too much fat and overall calories, while store-bought meals may not have enough of the fat children need to grow, according to a UK study. Meals made at home also tend to be cheaper for parents of young children and to offer a larger variety of vegetables, the researchers write in the Archives of Disease in Childhood. Because they are growing quickly, young children need more fat in their diets than adults, said lead author Sharon Carstairs, a public health researcher at the University of Aberdeen in Scotland Carstairs noted, though, that too much fat in the diet can also be an issue.
