Diabetic Seniors may have increased risk for fracture – Study

When it rains it pours. As if it weren’t difficult enough to be a senior citizen, it turns out that Type 2 diabetes adds a further level of complexity.

Though seniors with Type 2 diabetes (T2D) tend to have normal or higher bone density than their peers, researchers have found that they are more likely to succumb to fractures than seniors without T2D. In a new study published in the Journal of Bone and Mineral Research, researchers from Hebrew SeniorLife’s Institute for Aging Research found older adults with Type 2 diabetes had deficits in cortical bone–the dense outer surface of bone that forms a protective layer around the internal cavity– compared to non-diabetics. The findings suggest that the microarchitecture of cortical bone may be altered in seniors with T2D and thereby place them at increased risk of fracture.

Participants in this study included over 1,000 member of the Framingham Study who were examined over a period of 3 years. High resolution scanning allowed researchers to determine that many older adults with diabetes had weakness specific to cortical bone microarchitecture that cannot be measured by standard bone density testing.

Osteoporotic fractures are a significant public health problem that can lead to disability, decreased quality of life, and even death – not to mention significant health care costs. Risk of fracture is even greater in adults with T2D, including a 40 – 50% increased risk of hip fracture – the most serious of osteoporotic fractures.

“Fracture in older adults with Type 2 diabetes is a highly important public health problem and will only increase with the aging of the population and growing epidemic of diabetes. Our findings identify skeletal deficits that may contribute to excess fracture risk in older adults with diabetes and may ultimately lead to new approaches to improve prevention and treatment,” said Dr. Elizabeth Samelson, lead author of the study.

Researchers hope that novel studies such as this will help to revolutionize the area of bone health, especially for older adults. It is important to follow screening guidelines for bone density testing, but better understanding of all the factors that affect bone strength and the tendency to fracture is needed.

Are sugary drink interventions cutting consumption?

I have written repeatedly about the ill effects of soft drinks, both sugary and diet, on our bodies. You can check out my Page – What’s wrong with soft drinks? for chapter and verse. So this item in Medical News Today citing efforts to curb sugary drink consumption caught my eye.

An evaluation of efforts designed to reduce how many sugary drinks we consume shows some success in changing younger people’s habits but warns they cannot be the only way to cut consumption.

sugar

Nutritionists at the University of Leeds have carried out the first comprehensive review of interventions to reduce sugary drinks consumption. The team analyzed 40 studies with 16,500 participants across three age groups: children, teenagers and adults.

Their study, published in the Obesity Reviews journal, found that children participating in these programs reduced their sugary drink intake by around 30%, removing nearly 2.5 teaspoons of sugar from a child’s average intake of 16 teaspoons per day.

Interventions aimed at teenagers saw sugary drink consumption reduced by nearly 10%. However, there was almost no measurable change in adults participating in these programs. Continue reading

Cut diabetes risk by eating legumes – Study

I just wrote about how nuts improve cholesterol levels  three days ago.

Now comes a new study from overseas telling us how good legumes are for our bodies.

What-Are-Legumes.jpg

Recent results from the PREDIMED (Prevención con Dieta Mediterranea) study show a protective association between total legumes consumption, especially lentils, and the risk of developing subsequent type 2 diabetes after more than 4 years of follow-up of 3349 participants at high cardiovascular risk. Moreover, the present study shows that replacing a half a serving/day of eggs, bread, rice or baked potato with a  half a serving/day of legumes was also associated with a lower risk of type 2 diabetes.

Legumes are a food group rich in B vitamins, contain different beneficial minerals (calcium, potassium and magnesium) and sizeable amounts of fibre and are regarded as a low-glycemic index food, which means that blood glucose levels increase only slowly after consumption. Due to these unique nutritional qualities, eating legumes regularly can help improve human health. In fact, the Food and Agriculture Organization of the United Nations (FAO) declared 2016 as the international year of legumes to raise people’s awareness of their nutritional benefits.

Fructose is generated in the human brain

Fructose, a form of sugar linked to obesity and diabetes, is converted in the human brain from glucose, according to a new Yale study. The finding raises questions about fructose’s effects on the brain and eating behavior.

The study was published on Feb. 23 by JCI Insight.

Fructose is a simple sugar found in fruits, vegetables, table sugar, and many processed foods. Excess consumption of fructose contributes to high blood sugar and chronic diseases like obesity. The Yale research team had demonstrated in a prior study that fructose and another simple sugar, glucose, had different effects on brain activity. But it was not known whether fructose was produced in the brain or crossed over from the bloodstream.

To investigate, the research team gave eight healthy, lean individuals infusions of glucose over a four-hour period. They measured sugar concentrations in the brains of the study participants using magnetic resonance spectroscopy, a noninvasive neuroimaging technique. Sugar concentrations in the blood were also assessed.

Even mildly excessive body iron stores increase the risk of type 2 diabetes – Study

Diabetes was the seventh leading cause of death in the United States in 2010 based on the 69,071 death certificates in which diabetes was listed as the underlying cause of death. In 2010, diabetes was mentioned as a cause of death in a total of 234,051 certificates, according to the latest information from the American Diabetes Association.

In addition,  Diabetes may be under-reported as a cause of death. Studies have found that only about 35 percent to 40 percent of people with diabetes who died had diabetes listed anywhere on the death certificate and about 10 percent to 15 percent had it listed as the underlying cause of death.

Even mildly elevated body iron contributes to the prevalence and incidence of type 2 diabetes, according to research from the University of Eastern Finland. Excess body iron accumulation is a known risk factor of Type 2 diabetes in hereditary hemochromatosis, but the results presented by Dr Alex O. Aregbesola in his doctoral thesis show that elevated iron is a risk factor in the general population as well, already at high levels within the normal range.

Men accumulate more iron and are more at risk Continue reading

Study supports lower cut-off point for defining prediabetes

At the risk of being a wet blanket on Thanksgiving Day, this seems an appropriate topic.

Let’s face it the majority of us are bad eaters. Some 60 percent of us are overweight and half of them outright obese. Additionally, we are seeing adult onset diabetes occurring in teenagers. We need to start eating better and exercising more.

The health risks and mortality associated with prediabetes seem to increase at the lower cut-off point for blood sugar levels recommended by some guidelines, finds a large study published in The BMJ today.

does-being-a-diabetic-affect-my-chances-to-conceive.png

Prediabetes is a “pre-diagnosis” of diabetes — when a person’s blood glucose level is higher than normal, but not high enough to be considered diabetes. If left untreated, prediabetes can develop into type 2 diabetes. An estimated 79 million people in the US and 7 million people in the UK are thought to be affected. Continue reading

Type 2 Diabetes May Shrink the Brain, Study Suggests

They found that the longer a patient had the disease, the more brain volume loss occurred, particularly in the gray matter. Gray matter includes areas of the brain involved in muscle control, seeing and hearing, memory, emotions, speech, decision-making and self-control.

Loss of gray matter can lead to dementia, experts say.

People with type 2 diabetes may lose more brain volume than is expected as they age, new research indicates.

Surprisingly, this shrinkage doesn’t appear to be linked to the damaging effect of diabetes on tiny blood vessels in the brain, but instead by how the brain handles excess sugar, the researchers noted.

“We have known for a long time that diabetes is not good for the brain,” said lead researcher Dr. R. Nick Bryan, a professor of radiology at the University of Pennsylvania’s Perleman School of Medicine in Philadelphia.

Diabetes is associated with an increased risk for stroke and dementia, he said. Until now, doctors have thought these risks were likely related to blood vessel damage related to diabetes.

“But our study suggests that there is additional damage to the brain which may be more like a brain disorder such…
