Live Long and Prosper Newsletter #1

This newsletter was compiled from the latest research on health and longevity, by David Donohue, MD, FACP. 

Nutrition
1.   Dairy intake in relation to cardiovascular disease mortality and all-cause mortality: the Hoorn Study.
   Here's a plug for low fat dairy. Dutch people who ate high fat dairy had higher rates of death due to heart disease. Dairy intake itself (high or low fat) did not correlate with CVD or death in this study.

2.   Economic Costs and Benefits of Healthy Eating
   " We estimate the benefits of healthy eating in the United States to be $114.5 billion per year (in 2012 dollars) in medical savings, increased productivity, and the value of prolonged life"

Exercise
1.   Prevention of falls in the elderly--a review.
   These things have been shown in randomized trials, to reduce falls in the elderly: (1) regular, varied exercise program (like Tai-chi) (2) antislip shoe devices when icy (3) reduction of the total number of medicines especially sedatives (4) correct vitamin D deficiency which is common in this group (5) correct other conditions like cataracts, pacemakers where indicated

2.   Exercise and longevity.
   A 2008 meta-analysis showed that across 33 studies done to date, achieving greater fitness correlates with lower mortality. How much? About 33% if you adjust for other (related) variables like high blood pressure, cholesterol, and diabetes. If you do not adjust then the benefit is higher. Confused? Exercise ~30-60 minutes per day and you might add an extra hour per day onto your lifespan. So make sure it is something you love doing. Tennis anyone?

Lifestyle
1.   Does neuroticism make you old? Prospective associations between neuroticism and leukocyte telomere length.
   Neurotic people have shorter telomeres. Shorter telomeres correlate with older age and sooner death.

2.   Sufficient sleep duration contributes to lower cardiovascular disease risk in addition to four traditional lifestyle factors: the MORGEN study.
   Already have these 4 aspects of healthy lifestyle? * Sufficient physical activity (≥3.5 h/week cycling or sports), * a healthy diet (Mediterranean Diet Score ≥5), * (moderate) alcohol consumption (≥1 beverage/month), * non-smoking If you also get sufficient sleep duration (≥7 hours) then you are in a category with a further 65% reduction in cardiovascular disease.

Prevention
1.   Association between red and processed meat intake and mortality among colorectal cancer survivors.
   Among people diagnosed with colon cancer, those who ate the most red meat had 29% higher death rate from colon cancer than those who ate the least.

2.   Dietary Approaches to Prevent Hypertension
   "Dietary strategies for the prevention of hypertension include reducing sodium intake, limiting alcohol consumption, increasing potassium intake, and adopting an overall dietary pattern such as the DASH (Dietary Approaches to Stop Hypertension) diet or a Mediterranean diet."

Safety
1.   Increasing awareness of hypoglycaemia in patients with Type 2 diabetes treated with oral agents.
   If you have diabetes and take certain medicines (like insulin, glyburide) then you are at risk for hypoglycemia (low blood sugar). Hypoglycemia can kill, so take precautions! Check sugars regularly, explain hypoglycemia to your loved ones, be aware of the signs (sweating, elevated heart rate, confusion, anxiety, fatigue). If you can, look into switching to diabetic medicines that do not cause hypoglycemia.

2.   Temporal associations between spouse criticism/hostility and pain among patients with chronic pain: A within-couple daily diary study.
   Criticism of hostility from your spouse can make your chronic pain worse. We can speculate that spousal support is a form of pain reliever.

3.   Analyzing and modeling risk exposure of pedestrian children to involvement in car crashes.
   Who is most at risk to get hit by a car? "Most vulnerable are boys from a low socio-economic group who live in areas of high density and mixed land use near a major road and who tend to walk to and from school and additional activities after school."

Medication
1.   Sarcopenia as a risk factor for falls in elderly individuals: Results from the ilSIRENTE study
   As we get older, we lose muscle mass. Elderly folks who lose muscle mass have increased risk of falls. What can we do to increase muscle? Resistance training, exercise, dietary protein (especially at breakfast and lunch), and Vitamin D.

2.   A randomized controlled trial of cognitive behavioral therapy for adherence and depression (CBT-AD) in patients with uncontrolled type 2 diabetes.
   Many diabetics are depressed. If you are, seeing a mental health therapist can help both your depression and your control of diabetes.
