Artificially Sweetened Beverages, Stroke and Dementia Risk

An observational study in the Journal “ Stroke, A Journal of Cerebral Circulation” examined the question of whether there is an a relationship between consuming “ diet” beverages with artificial sweeteners and the development of a stroke or dementia using data from the Framingham Heart Study Offspring Cohort. They looked at 2888 individuals older than 45 years of age for the development of strokes and 1484 participants over age 60 for the development of dementia. They followed the group for ten years and were able to gauge their intake of artificially sweetened beverages from food questionnaires filled out at exams. After making adjustments for age, sex, education, caloric intake, diet quality, physical activity, and smoking they found that higher consumption of artificially sweetened beverages was associated with a higher risk of strokes and dementia. This was not seen in individuals drinking sugar sweetened beverages.

In a comment section, the author acknowledged that diabetic patients had a higher risk of stroke and dementia than the general public and they consumed more artificially sweetened beverages than others. While the study did not show cause and effect it does leave us wondering just how safe these diet drinks are?

Allergies Worsening Due to Climate Change

The American Academy of Allergy, Asthma and Immunology and the World Asthma Organization just concluded their joint congress in Orlando, Florida. One of the topics of concern is how climate change is making everyone’s allergy symptoms much worse.

We read about more powerful hurricanes and cyclones, seasonal tornadoes occurring out of season, horrible beach erosion and flooding due to large volume rains, lack of rain causing poor harvests leading to waves of migration for survival for animals and humans. Climate change also exacerbates allergy symptoms. Nelson A. Rosario, MD, PhD, professor of pediatrics at Federal University of Parana (Brazil) discussed longer pollen season and increased allergens caused by fallen trees and ripped up plants, mold growing following flooding and irritants in the air due to wildfires. An international survey in 2015 found that 80% of rhinitis patients blamed their symptom exacerbations on climate change items. Pollen seasons have more than doubled in some areas.

The argument should not be about whether climate change is due to cyclical planetary changes or man-made pollutants. It should be about what we can do as a society to maintain economic growth while limiting man made contribution to adverse climate changes. The health and survival consequences of not addressing this issue will ultimately involve our survival as a species.

Does Curcumin Use Help with Cognitive Dysfunction?

Recently, more and more patients have been adding curcumin or turmeric to their cooking to help with their memory. Curcumin is a metabolite of Turmeric and has been available in health food stores for years.

A study a few years back on Alzheimer’s patients published by J. Ringman and Associates showed no benefit in slowing the development of symptoms and no improvement in symptoms when supplied with curcumin. When they looked closely at their study, and analyzed the participant’s blood, they found that curcumin was not absorbed and never really entered the bloodstream.

Last month a study was published in the American Journal of Geriatric Psychiatry by Dr. Gary Small and colleagues. They looked at 40 patients with mild memory complaints aged 50 – 90.  Some were administered a placebo and others were administered nanoparticles of curcumin in a product called “Theracumin”. The participants were randomized and blinded to the product they were testing. The study designers felt the nanoparticles would be absorbed better than other products and would actually test whether this substance was helpful or not. At 18 months, memory improved in patients taking the nanoparticles of curcumin and they had less amyloid deposition in areas it usually found relating to Alzheimers Disease.

Robert Isaacson MD, the director of the Alzheimer’s Prevention Clinic at Weil Cornell Medicine and New York- Presbyterian, has been suggesting his patients cook with curcumin for years. Until the development of the Theracumin nanoparticles, cooking with curcumin was the best way to have it absorbed after ingestion. There is now some evidence to suggest that curcumin, in this specific nanoparticle form, may play a role in both the risk reduction and potential therapeutic management of Alzheimers Disease.

Can My Relative, the Physician, Review My Hospital Chart?

I practice in a community, Boca Raton, with a multitude of seasonal visitors. Many of these “snowbirds” have long term relationships with physicians “back home” and a developing relationship with their local physicians. When they become ill enough to be admitted to the hospital, I often get a request to allow a family member to review their medical chart. I have never objected to transparency, especially if it allows the patient and family to feel more comfortable with the caregivers and plan we are following.

When we used a paper chart the process was simple and involved writing an order in the chart to allow that family member to read the chart. I usually spoke with the patient’s nurse and the floor charge nurse to inform them of my permission. The family member simply sat in the patient room or at the nursing station with the complete medical record and reviewed it.

The switch to paperless charts has made it far more complicated. Giving patients’ relatives access to the chart now involves granting them access to the hospital computer record system. It now involves asking medical records to get involved and either devote time and cost of supplies (printing out records) or labor time – asking an employee to sit down with the family member and give them access. It is far more difficult than it once was.

I still grant them access but it must be through the hospital’s information technology and medical records department and protocol. This week I was asked by the physician son of a patient for permission to review his parent’s chart. I had no objection to this request as long as the son went through the medical records department protocol. This was poorly received by the son who saw my actions as an obstruction rather than a necessary process.

If anyone should be understanding regarding these protocols it should be that of a fellow physician.

Fitness Lowers Your Risk of Dementia

Over the years I have read and passed on to my patients the benefits of exercise on quality of life and healthy aging. This hypothesis was supported by a recent publication in the journal “Primary Care” by Peter Lin, MD, CCFP. Dr Lin and colleagues followed a group of woman aged 38 to 60 years for 44 years to determine the relationship between fitness and development of dementia. They chose to follow 191 women from a group of 1462 patients and selected a balanced number of patients in each age group up to age 60. They performed a physical fitness test on the women in 1968 and then grouped them into high fitness category, intermediate fitness category and low fitness category based on their performance in the physical fitness test. The women then received neuropsychiatric evaluations in 1974, 1980, 1992, 2000, 2005 and 2009.

The patients within the high fitness group showed an 88% reduction in dementia rate compared to those with medium fitness. Those in the lowest fitness group had a 41% increase d risk of dementia compared to the medium fitness group. Those patients in the high fitness group who developed dementia showed symptoms 9.5 years later on average than the patients in the medium fitness group.

The message for young adults is simple. Stay fit at a high level doing something you enjoy and you may reduce your risk of developing dementia by up to 90%.

Fish, Fish Oils and Cardiovascular Disease

Years ago the scientific researcher responsible for the promotion of fish oils as an antioxidant and protector against vascular disease recommended we all eat two fleshy fish meals of cold water fish a week. He continued to endorse this dietary addition and included canned tuna fish and canned salmon in the types of fish that produced this positive effect.

Over the years I heard him lecture at a large annual medical conference held in Broward County and he fretted about the growth of the supplement industry encouraging taking fish oils rather than eating fish. He worried about the warnings against eating all fish to women of child bearing age because of the fear of heavy metal contamination and knew that the fish oils and omega 3 Fatty Acids played a developmental role in a growing fetus and child.

I then attended lectures, in particular one sponsored by the Cleveland Clinic, during which they promoted Krill oil as the chosen form of fish oil supplements because it remained liquid and viscous at body temperature of 98.6 while others solidified. I listened to this debate only to hear the father of the science speak again and this time advocate that one or two fleshy fish meals a month was adequate to obtain the protective effect of Omega 3 Fatty acids. He felt that the supplements did not actually provide a protective effect as eating real fish did. Since I love to eat fresh fish I had no problem with this message but others are not comfortable buying and preparing fish at home or eating it at a restaurant. Supplements to them were the answer.

Steve Kopecky, M.D. examined the question in an article published in JAMA Cardiology this week. He looked at 77,917 high risk individuals already diagnosed with coronary artery disease and vascular disease who were taking supplements to prevent a second event. His study concluded that taking these omega 3 supplements had no effect on the prevention of recurrent cardiovascular events. The study did not discuss primary prevention for those who have not yet had a vascular illness or event.

Once again it seems that eating fish in moderation, like most anything, is the best choice. I will continue to eat my fresh fish meals one or two times per week, not necessarily for the health benefit but because I enjoy eating fresh fish.

I advise those worried about preventing primary or secondary heart and vascular disease to find a form of fish they can enjoy if they want this benefit. If you really wish to reduce your risk of a cardiovascular event; I suggest you stop smoking, control your blood pressure and lipid profile, stay active and eat those fresh fish meals.

Cleaning Is Hazardous to Your Lungs and Overall Health

In an article published in the American Journal of Respiratory and Critical Care Medicine it was shown that women who regularly clean homes show a marked decline in pulmonary function. The study looked at 6,230 persons participating in the European Community Respiratory Health Survey over a period of 20 years.

Normally lung function declines as we age but women who were professional home cleaners, and who used cleaning sprays, declined at a far faster rate than women who did not clean at home or professionally. For unclear reasons in this study cleaning did not appear to effect the measurements on men. The study authors were quick to point out that there were very few men in the study making their conclusions on men less meaningful.

The authors looked at two main parameters, Forced Vital Capacity (the maximum amount of air exhaled after a maximum inspiration) and Forced Expiratory Volume in one second. They noted that decrease in Forced Vital Capacity is associated with decreased long term survival in patients without known pulmonary disease. They additionally noted a slight increase in the development of asthma in the home cleaners.

The authors postulated that cleaning products were “low grade irritants” and chronic exposure could lead to remodeling of the airways and resultant decline in pulmonary function. While reading this article I thought about how infrequently we read labels on the products we use to clean our homes, cars and elsewhere before using them. How often do we actually follow the health advice listed on the bottle? Should we be wearing N95 respirator type masks when using cleaning sprays and working in sparsely ventilated areas? What about children and their exposure? Should we be using these products around them and or our pets? Is it the actual spraying that exposes cleaners or does the products effects linger well after use?

These are all questions that few, if anyone, looks into or answers but certainly need to be addressed now that these findings have been published.
