Weekly Health Update:

Mental Attitude: Why Do We Feel Jealousy? A new animal study suggests that a basic form of jealousy has evolved in order 
to protect social relationships from outside threats. In the study, jealousy in dogs appeared to be driven by a desire to protect its 
relationship with its owner. Understanding the mechanisms underlying jealousy in humans is important, as it is the third-leading cause of non-accidental homicide. Researcher Dr. Christine Harris adds, "Many people have assumed that jealousy is a social 
construction of human beings - or that it's an emotion specifically tied to sexual and romantic relationships. Our results 
challenge these ideas, showing that animals besides ourselves display strong distress whenever a rival usurps a loved one's 
affection." University of California, San Diego, July 2014 

Health Alert: Blood Thinning Drug Safety Concerns. An investigation by the British Medical Journal has noted concerns 
about a leading blood thinning drug and the regulatory decisions that led to its approval. Pradaxa is one of the new generations 
of drugs for stroke prevention in patients with non-valvular atrial fibrillation. Unlike medications like Warfarin, it is not 
considered necessary to monitor plasma levels and anticoagulant activity to adjust the dosage. Investigators found that the 
drug's creator, Boehringer Ingelheim, failed to share information with regulators on the benefits of monitoring anticoagulant 
activity and adjusting the dosage to ensure efficacy and safety, in addition to how many major bleeds could be prevented by 
doing so. The drug maker claims that the information was withheld because the analyses were not reliable.

Diet: Diet Changes Alter Gut Bacteria. By analyzing stool samples and lifestyle factors of two individuals over a one-year 
period, researchers discovered that the balance of bacteria in the gut is altered dramatically on a daily basis by dietary changes. 
Developing ways to monitor such fluctuations might help detect and ease flare-ups for individuals with chronic illnesses like 
ulcerative colitis and Crohn’s disease. Genome Biology, July 2014 

Exercise: Workday Fitness Tips. The American Council on Exercise provides these tips to help you fit exercise into your 
workday: bike or walk to work, arrive early and walk for 30 minutes near your work, take a lunchtime walk, join a fitness center near work, use the stairs, and keep elastic tubing at your desk for quick workout. American Council on Exercise, July 2014 

Chiropractic: Acetaminophen No More Effective than Placebo for Acute Back Pain. A large randomized-trial investigating 
the efficacy of acetaminophen for acute low back pain found that it performs no better than a placebo in regards to recovery 
time. The median time to recovery was 17 days for the regular acetaminophen group, 17 days for the as-needed acetaminophen 
group, and 16 days for the placebo group. The researchers also found that acetaminophen provides no benefit for short-term 
pain levels, disability, function, sleep quality, or quality of life. The Lancet, July 2014 

Wellness/Prevention: Coffee May Aggravate Hot Flashes. Data from a new survey finds that drinking caffeine may worsen 
the hot flashes and night sweats that affect roughly two thirds of women during menopause. Researcher Dr. Stephanie Faubion 
adds, "While these findings are preliminary, our study suggests that limiting caffeine intake may be useful for those 
postmenopausal women who have bothersome hot flashes and night sweats." To help limit the discomfort of menopausal 
symptoms, Dr. Faubion and his team recommend avoiding caffeine, maintaining a healthy weight, staying active, adopting 
meditative techniques, dressing in removable layers, and sleeping with moisture-control bedding. Menopause, July 2014
