Some Cholesterol Medications May Impair Memory. Scientist recently tested two popular statins (medications used to 
lower cholesterol levels) on rats for 18 days. They found that pravastatin impaired the rats' ability to perform simple learning and memory tasks. These effects reversed soon after the rats stopped consuming the drug. Atorvostatin, the other statin in the test, did not appear to have the same impact on learning and memory.

Health Alert
Over 40 Million Cases of Poor Care in Hospitals Every Year Worldwide. A recent worldwide analysis has revealed that 
every year there are approximately 43 million episodes of harm caused by poor hospital practices. Researchers focused on seven markers for substandard care: harm from prescribed medications, urinary tract infections associated with catheters, bloodstream infections associated with catheters, pneumonia acquired in the hospital, blood clots, falls, and bed sores. The authors calculated an annual loss of about 22.6 million years of life to death or disability as a result of substandard care.

Physical Activity and Postmenopausal Breast Cancer. In a study of over 73,000 postmenopausal women, those who walked for 
seven hours a week had a 14% reduced risk of being diagnosed with breast cancer compared to women who walked under three hours per week. Women who walked more than seven hours a week and who also performed more vigorous exercises had up to a 25% reduced risk. This study also noted that obesity did not play a factor in results, and women obtained benefits regardless of their body mass.

High-Intensity Exercise and Heart Disease.  High-intensity exercise is a popular and time-saving method for getting fit and protecting against coronary heart disease.  High-intensity training occurs when an individual's heart rate (HR) is 85-95% of HR max. One way 
to calculate your HR max is to subtract your age from 220. For example, the HR max for a 40 year-old adult is 180 (220-40=180). A new study has found that high intensity exercise can also be utilized by patients who already have coronary heart disease to get into shape. In a 12-week study, participants utilized the 4x4 model: 4 minutes of high-intensity exercise followed by 3 minutes of less intense exercise, repeated 4 times. Researchers used the participants' VO2 max (maximal oxygen intake) to measure progress. Participants who exercised at an intensity that was greater than 92% of their HR max during the high-intensity periods experienced greater improvements in their VO2 max compared 
to participants who exercised at the lower range of HR max. This indicates that there is a dose-response relationship even in the 85-95% high-intensity zone.

Chiropractic Outperforms NSAIDs and Acupuncture. A pilot study involving 77 patient with chronic spinal pain received either nonsteroidal anti-inflammatory drugs (NSAIDs), acupuncture, or spinal manipulation. After 30 days, spinal manipulation was the only intervention that achieved statistically significant improvements according to outcome assessments.

Combining Chinese and Western Medicine for Cancer Patients. Xiaoji is a traditional Chinese formula consisting of 14 herbs has been shown to be beneficial to cancer patients, but scientists did not know why… until now. New research presented at the 
European Cancer Congress last month revealed that Yangzheng Xiaoji works by blocking a pathway which stops the spread of cancer cells in the body. Combing Yangzheng Xiaoji with conventional therapies, such as chemotherapy, may lead to more effective treatments in the near future for liver, lung, colorectal, and bone cancer.
