Diabetes: Low Blood Sugar

en-nejatgar — Fri, 12 Nov 2010 15:57:00 GMT

Low blood sugar is called hypoglycemia. Blood sugar below 70 mg/dl is considered low. Blood sugars below this level can harm you.

If you have diabetes and are taking any of these diabetes medications, you have a risk for low blood sugar:

• Insulin

• Chlorpropamide (Diabinese), tolazamide (Tolinase), acetohexamide (Dymelor), glipizide (Glucotrol), or tolbutamide (Orinase)

• Glyburide (Micronase), glimepiride (Amaryl), and repaglinide (Prandin), nateglinide (Starlix), and mitiglinide (Glufast). (The risk with these drugs is lower, but still possible.)

Recognizing Low Blood Sugar

Low vitamin D predicts dementi

en-nejatgar — Fri, 16 Jul 2010 19:12:00 GMT

Low levels of the sunshine vitamin can be used as an early warning sign for being at an increased risk of developing dementia in the elderly, a new study says.

Previous studies have pointed out the protective role of vitamin D against cancer, artery disease and tuberculosis. Certain others have noted that adequate dietary intake of vitamin D can ward off neurological disorder such as Parkinson's.

According to the study published in the Archives of Internal Medicine, severe vitamin D deficiency, defined by blood levels of 25-hydroxyvitamin D lower than 25 nanomoles per liter, can place the elderly at an increased risk of having problems with memory, learning and thinking.

The condition is reported to increase the risk of substantial general cognitive decline by 60 percent. These individuals are also believed to be 31 percent more likely to experience problems with mental flexibility.

"This is the first study to identify a clear link between low vitamin D levels and cognitive decline," said lead researcher David Llewellyn.

He added that Vitamin D prevents the degeneration process in the brain tissue through influencing the formation of nervous tissue, maintaining calcium levels or clearing the beta-amyloid plaques which are characteristic for Alzheimer's disease.

Scientists believe the cheap and safe vitamin D supplements can be used as a promising therapeutic target to prevent not only osteoporosis and the risk of falls and fracture but also dementia in the elderly.

Young and fat, recipe for early death

en-nejatgar — Fri, 16 Jul 2010 19:10:00 GMT

Men who are obese at the age of 20 have a higher risk of early death than average people, a new study suggests.

According to a study presented at the International Congress on Obesity in Stockholm, Sweden, obese men in their 20s are twice likely to die young.

Study researcher for Copenhagen University Hospital in Denmark, Esther Zimmermann, told the website WebMD that "entering adult life as obese leads to a life-long doubling of the risk of dying prematurely…

The best advice is to avoid beginning adult life as obese [because] if you enter adult life as obese, the majority will remain obese as adults.

" The researchers studied some 5,500 Swedish males aged 20 to 80. They found that 1,930 cases who were overweight or obese at the age of 20 were twice likely to die young than their opposite number who were not obese at that age.

The study found that once both groups reach the age of 55, those who were obese at the age of 20 on average die eight years earlier than the fitter cases at that age. Individuals with a body mass index (BMI) of above 30 are considered as obese.

A BMI of 25 means being overweight. The study found that the obese sample group's chance of dying younger increased by "10 percent for each BMI unit above 25," WebMD reported.

The research used follow-up surveys for ages 35 and 46. About 70 percent of 20-year-old obese men stayed obese during follow-ups, while only 4 percent of those not obese had a BMI of over 30. Zimmermann said, "Entering adult life as obese had a life-long effect on mortality.

" As obesity is a major factor for diabetes and heart problems, Dr. Randall Urban, Chair of Internal Medicine at the University of Texas says, "This is a valuable study, and I think the results raise a lot of questions such as why are people who are obese at age 20 are dying sooner…

We need to break down why they did worse and see how many people develop diabetes or heart problems." "This is a fascinating beginning and we really need to dig down further in this group to understand why they are dying earlier," he added. He believes that such data helps finding helpful strategies. "Obesity is a marker that there will be problems down the road," he says.

"In broad strokes, we can say that if obese people change their lifestyle, they will do better, but there may be more to it than this," Urban says.

AIDS has claimed 25 million lives worldwide

en-nejatgar — Sat, 28 Nov 2009 07:29:00 GMT

The number of deaths from HIV/AIDS in different parts of the world has topped 25 million, the World Health Organization (WHO) and the Joint UN Program on HIV/Aids (UNAIDS) report says.

According to the report recently released by the WHO and UNAIDS, an estimated 33.4 million individuals across the globe are HIV positive. The report stated that nearly 60 million individuals including the 25 million deaths have been infected by HIV since the epidemic started.

Despite the high number of infected individuals worldwide, the figures show that less people are dying from HIV.

The use of anti-retroviral drugs is believed to account for the 10% reduction in the HIV/AIDS-related death toll over the past five years. In other words, these drugs have saved some 2.9 million lives since their introduction in 1996.

Latest figures also showed a significant drop, equal to 17 percent over the past eight years, in the number of new HIV infections, which can be attributed to the effective drugs that prevent the spread of the virus as well as the established HIV prevention programs.

The report stated that Africa is still the worst country hit by the virus although the number of new infections has fallen by around 15% since 2001. It also stressed that the disease is responsible for half of all maternal deaths on the continent.

Electric shock treats teeth grinding

en-nejatgar — Wed, 04 Nov 2009 07:30:00 GMT

A mild electric shock can help treat patients complaining of nighttime teeth grinding, overcoming their daytime sleepiness.

Teeth grinding or bruxism is a common and usually harmless sleeping habit induced by sleep apnea, high levels of anxiety and depression.

Untreated bruxism can lead to excessive tooth wear and decay, periodontal tissue damage, jaw pain and temporomandibular joint or TMJ pain, headaches, and sleep disturbances.

Wearing a mouthguard when sleeping to prevent the top and bottom teeth from meeting and using certain painkillers along with relaxation therapies are the common ways used to treat the condition.

"The broken sleep pattern caused by grinding can exacerbate any stresses or worries already being felt by the patient, and add an extra layer of anxiety to their lives," said lead researcher David Vivian.

He added that the new device would improve not only the quality of sleep but also the psychological and physical problems associated with grinding. Grindcare is a small electrode placed on the temple which monitors the movement of facial muscles and delivers tiny electrical impulses or biofeedback as soon as it detects the initiation of grinding.

The impulse, which helps relax the muscles, is not consciously detected by the sleeping patient. It, however, causes headaches and stiff necks. The device has shown promising results in reducing grinding by as much as 80% within two months.

Men at higher risk for cancer

en-nejatgar — Thu, 18 Jun 2009 22:16:00 GMT

A new study has found that men are more vulnerable to developing cancer and subsequently dying from it.

Excluding breast, lung and other cancers that are gender specific, the differences between the genders are reported to be considerable.

According to a study published in Men's Health Forum, men are significantly more prone to being diagnosed with and dying from any type of cancer apart from melanoma.

Men are reported to be 60% more likely to develop cancer and 70% more likely to die from it.

Scientists were unable to find any known biological reason for the higher risk of cancer among men; they, however, claimed that men are less health conscious compared to women.

"What we see from this report could be a reflection of this attitude, meaning men are less likely to make lifestyle changes that could reduce their risk of the disease and less likely to go to their doctor with cancer symptoms," said Alan White, the lead researcher of the study.

Men do not seek medical advice in the early stages of the disease; many of them also follow unhealthy lifestyles.

Men are believed to be less aware of the adverse effects of smoking, having extra weight around the waist, having a high alcohol intake, a poor diet and having a positive family history for malignancies contributing to the increased risk of cancer.

Scientists therefore urge men to adopt a healthy lifestyle, adding that the majority of cancers can be prevented through lifestyle changes.

Sunshine vitamin fights 'mental decline'

en-nejatgar — Sat, 30 May 2009 16:36:17 GMT

Vitamin D is reported to play a critical role in keeping the brain in a good condition and prevent mental decline in old age.

While previous studies have indicated that vitamin D can protect individuals against cancer, artery disease and tuberculosis, a new study reveals that high levels of the sunshine vitamin can ward off mental decline.

According to a study published in the Journal of Neurology Neurosurgery and Psychiatry, high levels of vitamin D slow down the ageing process in the brain, preventing dementia and memory loss commonly experienced in old age.

Elderly folk who achieve vitamin D levels higher than 35 nanomoles per liter are reported to perform better on visual scanning, memory and information processing tests.

Produced by the body when skin is exposed to sunlight, vitamin D protects cells and key signaling pathways in the brain, perking up its performance.

Scientists conclude that inadequate amounts of vitamin D in a person's regular diet can alter the mental performance in old age; they therefore urge individuals to add vitamin D supplements with the aim of tackling or preventing dementia.

Antacids ups pneumonia-related deaths

en-nejatgar — Sat, 30 May 2009 16:33:48 GMT

The routine practice of acid-reducing medications for non-acid reflux related purposes accounts for an estimated 33,000 deaths a year.

Proton pump inhibitors and other acid-suppressing drugs known as H2 blockers are commonly prescribed for more than 50% of the hospitalized patients with the aim of reducing the risk of stress-related ulcers, which can be life threatening.

According to a study published in the Journal of the American Medical Association, the regular use of these drugs increases the risk of hospital-acquired pneumonia in patients with a very low risk for developing ulcers by 30 percent.

Acid-suppressive medications are believed to alter the bacterial flora of the respiratory tract, placing the individual at a greater risk of developing pneumonia.

Scientists therefore urged physicians not to prescribe acid-suppressing drugs in non-ventilated, non ICU-treated patients with a low risk for developing stress ulcers routinely.

They, however, stressed that hospitalized and non-hospitalized individuals taking these medications for symptoms such as frequent heartburn or ulcers should not stop taking them, adding that the pneumonia risk in these individuals is reportedly low.

Sunny summer days up suicide rate

en-nejatgar — Mon, 11 May 2009 00:09:40 GMT

Font size : Despite the belief that the rate of suicide is higher in autumn and winter, a new study finds long summer days increase the number of suicides.

Previous studies had reported that sleep disturbance caused by longer hours of darkness in autumn and winter contributes to the increased risk of suicide in adolescents and those with psychiatric disorders.

This is while the new study conducted at the Karolinska Institute reported that too much sun exposure in summer can drive individuals to the point of suicide.

"During the long periods of constant light, it is crucial to keep some circadian rhythm to get enough sleep and sustain mental health," said Karin Sparring Bjorksten, the team leader of the study. According to the study published in BMC Psychiatry, 82 percent of suicides in Greenland occur during daylight months.

Most of these suicides are committed via violent methods such as shooting, hanging and jumping from high altitudes. Light-generated imbalances in serotonin, the brain chemical linked with mood disorders, are believed to be responsible for the increase in impulsivity and insomnia, the two main factors leading to suicide.
