This inexpensive and simple method also improves the nutritional status of patients and has the potential to translate into economic benefits, quality of life and clinical studies.

A daily dose of sodium bicarbonate slows the deterioration of renal function in some patients with chronic kidney disease (CKD) Advanced, a study of the Royal London Hospital in the UK that is published in the Journal of the American Society of Nephrology

As explained Magdi Yaqoob, director of the study, involving 134 patients with chronic kidney disease and low levels of bicarbonate or metabolic acidosis. One group received a small daily amount of sodium bicarbonate in tablet form along with their treatments. In this group, the rate of decline of renal function is greatly reduced, about two-thirds less.

“In fact, patients taking sodium bicarbonate, the rate of decline in renal function was similar to normal deterioration associated with age,” says Yaqoob.

The rapid progression of renal disease occurred in only 9 percent of patients taking sodium bicarbonate compared to 45 percent in the other group. Patients taking bicarbonate also were less likely to develop end-stage renal disease requiring dialysis.

According to investigators, patients taking bicarbonate also improved on several measures of nutrition. Although their sodium levels rose, this did not lead to any problem of increased blood pressure.

The low bicarbonate levels are common in patients with chronic kidney disease and may lead to a wide variety of problems. “This is the first randomized controlled study of its kind. A simple remedy like baking partner, when used appropriately, can be very effective,” concludes Yaqoob.

The researchers note that their study had some limitations exist as with placebo group and the scientists knew which patients were taking sodium bicarbonate. “Our results will require validation in a multicenter study,” adds the researcher.

A study finds that the risks of transplant failure and death will increase if the organ comes from a dead man

According publishes the Journal of the American Society of Nephrology “, Canadian researchers have found that recipients of female kidneys, which donated organ came from a dead man face greater risk of failure during the first year after transplantation

The authors say the risk is short term, however. It could be caused by proteins of male donor cells. Their study found that the risk disappears after ten years.

The researchers analyzed data on 117,877 adults whose kidney transplants were performed in the United States between 1990 and 2004. The kidneys were from deceased donors. Within a year, the failure of the transplant had occurred in 6878 and 16,135 people had died. Among the 97,906 people who were followed for up to ten years after transplantation, there were 35,084 and 22,566 transplant failure deaths.

Year risk of graft failure

In comparison with other combinations of gender, recipients of kidneys from men had a 12% higher risk of failure and an increased risk of death similar one years after transplantation. They had no greater risk of failure or death after decade.

The researchers, from the University of Toronto and the University of British Columbia, noted that the HY antigens derived from the male chromosome that are not present in women could cause adverse immune responses in women who receive kidneys from men who have died.

They recommended that “future research should examine potential mechanisms underlying the HY effect to better understand the specific role of minor histocompatibility antigens in determining the outcome of allergenic transplants.

A healthy diet helps prevent kidney stones, according to a Maine Medical Center Hospital and Brigham and Women in Boston (USA) published in the Journal of the American Society Nephrology.

According to the authors, the consumption of fruits, vegetables, nuts, low-fat products and integrals, limit salt and red and processed meat and sweet drinks is an effective way to prevent kidney stones.

The scientists, led by Eric Taylor Maine Medical Center, collected information from individuals who participated in three trials: one for monitoring of health professionals (45,000 men followed 18 years), the Nurses Health Study (94,108 women followed 18) and the second study health nurses (101,837 women followed 14 years).

The researchers assigned a score to each participant according to eight components of the lifestyle of the DASH diet: high consumption of fruits, vegetables, nuts and vegetables, skimmed and comprehensive products and low consumption of salt, sweet drinks and red and processed meats. Those with the highest scores in this type of diet consumed higher levels of calcium, potassium, magnesium, oxalate and vitamin C and less sodium.

In total, 5645 participants developed kidney stones in the three studies. In each study, participants with higher scores on adherence to the DASH diet were at 40 and 45 percent lower risk of developing kidney stones that participant who followed these guidelines less food.

The researchers also performed an analysis limited to participants without hypertension or diabetes, and that diet could affect the development of hypertension, diabetes and other chronic diseases associated with kidney stones. The results showed that even in these individuals, the DASH diet reduced the risk of kidney stones.

The investigation showed that the high diastolic pressure leads to a weakening of the small arteries in the brain, which can lead to the development of small areas of brain damage

High blood pressure is linked to memory problems in people over age 45, according to an article published Tuesday, the journal Neurology, the American Academy of Neurology.

The study found that people with high diastolic pressure, which is low in a blood pressure reading are more likely to have cognitive problems, memory or related to thinking skills than people with normal diastolic reading.

For each point (10 points in reading U.S.) increase in reading, the chances that a person has cognitive problems increase by 7%.

The results remained valid even after being weighted with other factors that may affect cognitive abilities, such as age, smoking, exercise level, education, diabetes or high cholesterol.

The study involved nearly 20 thousand people over 45 years of age throughout the country who had participated in an investigation of geographic and racial differences in stroke, and never had suffered a heart attack or micro infarctions.

A total of 506 participants thousand, i.e. 7.6%, suffered from cognitive problems, and nine thousand 844, ie 49.6%, taking medication for high blood pressure.

High blood pressure is defined as a reading of 12 / 9 (140/90) or higher.

“It is possible that by preventing or treating high blood pressure can prevent cognitive impairment that may be precursors of dementia,” explained study author Georgios Tsivgoulis, University of Alabama at Birmingham, and member of the American Academy of Neurology.

The investigation showed that the high diastolic pressure leads to a weakening of the small arteries in the brain, which can lead to the development of small areas of brain damage.

Tsivgoulis added that more research is needed to confirm the relationship between high blood pressure
