'Get Outside And Embrace The Cold:' Gestational Diabetes Linked To Warmer Temperatures

'Get outside and embrace the cold:' Gestational diabetes linked to warmer temperatures

Canadian researchers have uncovered a direct link between risk of gestational diabetes and what may at first seem like an unlikely source: outdoor air temperatures.
In Monday's issue of the Canadian Medical Association Journal, researchers report the relationship they found after checking records of nearly 400,000 pregnant women in the Greater Toronto Area who gave birth between 2002 and 2014.
"This is the first population study showing this relationship between air temperature and gestational diabetes risk," said lead author Dr. Gillian Booth, a scientist at St. Michael's Hospital and the Institute for Clinical Evaluative Sciences.
Alicia Dubay's gestational diabetes illustrates the stakes for women at high risk of developing the condition. Left untreated, the temporary form of diabetes in pregnancy can result in stillbirth, increase the risk of having a difficult delivery and increase the risk of developing Type 2 diabetes for mom and baby.
"I remember after I got my diagnosis, I called my husband crying really, really hard, because I was nervous and worried about it what it meant for me and for my baby," Dubay, 32, recalled.
Women typically take a glucose drink test 24 to 28 weeks into their pregnancy to see if their blood sugar levels are high.
Dubay's baby girl, Seraphina Rose, was born healthy and full term at 37 weeks in December 2015. A short stay in the neonatal ICU to check that the infant was fine at regulating her blood sugars was the only effect related to the Brampton, Ont., mom's gestational diabetes.
"There were a few things that were really challenging," Du Continue reading

Excessive copper in diabetes impedes ability to make new blood vessels

It's a metal we worry thieves will steal from our air conditioners or power lines, but inside our bodies too much copper can result in a much larger loss.
Scientists have evidence that in diabetes, copper can pile up inside our cells, wreaking havoc on our ability to make new blood vessels, called angiogenesis. This impaired ability occurs even as the disease makes existing blood vessel walls less flexible, more leaky and more prone to accumulate plaque deposits and scars that impede good blood flow.
Impaired angiogenesis contributes to a host of problems from heart attacks to nerve death to loss of limbs to poor wound healing.
The problem is the disease alters the healthy copper balance that more typically enables new blood vessel formation, says Dr. Tohru Fukai, vascular biologist and cardiologist in the Vascular Biology Center at the Medical College of Georgia at Augusta University.
Treatments that target ATP7A, a copper transporter that normally helps ensure healthy copper levels for a wide variety of functions in our body, may one day help patients with diabetes recover the innate ability to make healthy new blood vessels, Fukai says.
"Normally copper is essential for angiogenesis," says Dr. Masuko Ushio-Fukai, also an MCG vascular biologist. "But in inflammatory diseases such as diabetes, copper levels within cells become excessive. In this excess copper state, what happens?"
Diabetes affects nearly 10 percent of the adult American population, according to the Centers for Disease Control and Prevention. Fukai and Ushio-Fukai are coinvestigators on a new $2.7 million g Continue reading

5 Important Tests for People With Diabetes

M onitoring blood sugar is just one essential test for people with diabetes. Read on for 5 others critical to your health...
If you have type 2 diabetes, your blood sugar isn’t the only thing that needs monitoring.
Your doctor will want to see a few more lab test results to ensure your liver, kidneys, heart and other organs are in good working order.
“If you have diabetes, you’re much more likely to have cardiovascular disease, which leads to heart attack and strokes, and to have issues with your liver and kidney functions,” says Sethu K. Reddy, MD, chief of the adult diabetes section at Harvard University Medical School’s Joslin Diabetes Center and author of The Cleveland Clinic Guide to Diabetes (Kaplan).
“It really pays to be aggressive in keeping these issues under control,” Dr. Reddy says.
Start with the ABCs of blood tests: A1C, blood pressure and cholesterol, he advises. You often can get these tests done at your local pharmacy, mobile health clinic or doctor’s office.
And follow your doctor’s advice on what these and other tests reveal about your overall health.
Here are the 5 top tests that help you stay healthier. We break down what the numbers mean and what you can do if you get a test result your doctor doesn’t like. Continue reading

Tired of taking pills for diabetes? How about a shot of broccoli?

Pills, pills, pills. It seems every ailment — from headaches to high blood pressure — needs them. But, what if you could swap the medication for vegetables?
An international group of researchers envision such a future for type-2 diabetics based on new results published Wednesday in the journal Science Translational Medicine. Their findings show how a compound found in broccoli improves diabetic outcomes to an extent that rivals the go-to drug treatment, with fewer severe side effects.
“To many patients, it might be more attractive to take a broccoli shot or drink than having to take another pill,” said Anders Rosengren, at the University of Gothenburg in Sweden and the study’s senior author.
Diabetes afflicts more than 400 million people worldwide, four times as many people as in 1980. Part of the problem is the disease can progress unnoticed for years, even decades, until severe complications like compromised kidney function arise.
“It’s why we need to be so active with this disease so we have the proper treatment at early stages,” Rosengren said.
Their project wants to find an alternative for metformin, a gold-standard drug that tackles a hallmark of diabetes: runaway production of glucose in the liver. Insulin normally keeps glucose on a tight leash, but becomes dysregulated in diabetes. Although metformin works well, it has a few problems.
“One problem is that it cannot be taken by people with poor kidney function,” Rosengren said, yet poor kidney function is one of the most common complications of type-2 diabetes. And metformin can cause side effect Continue reading

As Temperature Rises Does the Risk of Gestational Diabetes Spike?

The higher the thermometer climbs outside, the higher the risk of gestational diabetes, according to Canadian researchers.
In the database study, and after adjusting for influential risk factors, each 10°C increase in mean 30-day outdoor air temperature was associated with a 6%-9% relative increase in the risk of gestational diabetes mellitus, according to Gillian Booth, MD, of St. Michael's Hospital in Toronto, and colleagues.
Gestational diabetes occurred among 4.6% of women who were exposed to extremely cold mean outdoor air temperatures (≤ -10°C) in the 30-day period before screening. That percentage increased to 7.7% among those exposed to overly hot mean 30-day temperatures (≥ 24°C). Each 10°C increase in mean 30-day temperature was associated with a corresponding 1.06 (95% CI 1.04-1.07) times higher likelihood of gestational diabetes, after adjusting for factors including maternal age, parity, neighborhood income quintile, world region, and year, they wrote in the CMAJ.
"We observed a direct relation between outdoor temperature and the risk of gestational diabetes among nearly 400,000 women residing in a single urban area in Canada," Booth stated in a press release.
Booth's group used databases at the Institute for Clinical Evaluative Sciences and included women in the greater Toronto area who gave birth from Apr. 1, 2002 to March 31, 2014. Those with "extreme" preterm (<28-week gestation) or post-term (>42-week gestation) births were excluded from the study population, as were those who had type 1 or type 2 diabetes before they became pregnant.
Ultimately, 5 Continue reading
