Stressful job can increase risk of asthma

London May 27 (IANS) Being part of a stressful job can increase a person’s risk of developing asthma by 40 percent, reveals a new study.

The research led by Heidelberg University in Germany tracked 5,000 men and women aged between 40 and 65 over eight years. They found that among those free of asthma at the start of the project, there was up to a 40 percent higher incidence of asthma eight years later if they suffered stress at work.

The signs were long working hours, demanding schedules and uncomfortable working conditions.

‘Our study suggests work stress and the inability to relax after work are associated with an increased risk of asthma,’ dailymail.co.uk quoted the report as saying.

Earlier studies have shown stress can lead to the release of chemicals that promote allergies and disrupt the way the body halts inflammation of the airways.

However, the team stressed that the absolute risk of someone developing asthma because they are overloaded at work is still very small.

The study appears in journal Allergy.

Easter eggs ‘can help the heart’

Easter eggs and other chocolate may be good for the heart and lower blood pressure provided you eat a tiny amount each day and prefer dark rather than milk or white chocolate, new research suggests.

A study of more than 19,000 Germans showed those who ate an average of seven or more grams of chocolate per day had lower blood pressure and a lower risk of stroke and heart attack.

“To put it in terms of absolute risk, if people in the group eating the least amount of chocolate… increased their chocolate intake by six grams a day, 85 fewer heart attacks and strokes per 10,000 people could be expected to occur over a period of about 10 years,” said lead researcher Brian Buijsse of the German Institute of Human Nutrition.

The paper, published online in the European Heart Journal, says further work is needed to explain why chocolate appears to help the heart.

Previous research has suggested that the answer may lie in complex molecules called flavanols, which recruit the gas nitric oxide to the cells that line the inner walls of blood vessels. Nitric oxide causes smooth muscles to relax, which may lower blood pressure.

Flavanols are found in cocoa – and as there is more cocoa in dark chocolate, this could explain why milk chocolate or white chocolate were found to be less effective, the paper says.

Professor Peter Howe from the University of South Australia says the risk of heart attack and stroke was reduced by almost 40 per cent.

“The outcome is fairly convincing that even when people are consuming just regular chocolate, there is an overall benefit with slightly lower blood pressure and apparently less risk of cardiovascular disease,” he said.

The researchers were quick to warn that the study does not endorse the overeating of chocolate, which will result in serious health problems.

The experts warn anyone tempted to gorge on chocolate as a result of these findings.

A 100-gram slab of dark chocolate contains roughly 500 calories, so you would have to subtract this figure from your daily food intake – or do exercise to burn it up – to avoid weight gain.

“Small amounts of chocolate may help to prevent heart disease, but only if it replaces other energy-dense food, such as snacks, in order to keep body weight stable,” Mr Buijsse said.

Prostate cancer therapy ‘ups risk of bone, heart-related problems’

Washington, Apr 27 (ANI): Prostate cancer patients who undergo therapy to increase testosterone levels are more likely to suffer from bone- and heart-related problems, says a new study.he research team, led by Lockwood Taylor, MPH, of the University of Texas Health Science Centre, revealed that androgen deprivation therapy (ADT) used to increase testosterone levels can cause a variety of side effects including skeletal and cardiovascular complications, sexual dysfunction, periodontal disease, and mood disorders.

Bone and heart complications are among the most serious side effects associated with ADT.

After reviewing 14 studies, the researchers found that men treated with ADT for prostate cancer had an increased risk of bone fractures and heart-related death, although the absolute risk for both was still low.

Prostate cancer patients undergoing the therapy are at a 23 percent increased risk of suffering bone fractures.

For heart-related death, the increased risk among ADT-exposed men was 17 percent higher compared to other prostate cancer patients.

“While the absolute risks of fracture and cardiovascular mortality are low among men treated with androgen deprivation therapy, preventive treatments may further reduce the risk of these serious adverse outcomes related to androgen deprivation therapy,” the authors wrote.

The study appears in Cancer, a peer-reviewed journal of the American Cancer Society. (ANI)

Pre-diabetes, an epidemic that Indians need to be concerned about

New Delhi, Jan.13 (ANI): Pre-diabetes is a condition where blood glucose levels are higher than normal, but not high enough to be called diabetes.

Pre-diabetes has been shown to have harmful effects on the body in the long run, and is a disease that Indians need to be concerned and informed about.

A pandemic of obesity and diabetes is occurring. Diabetes now affects an estimated 24.1 million people in the United States, an increase of over three million people in approximately two years.

Another 57 million people in that country have pre- diabetes, some of whom in fact already have micro-vascular changes (such as blindness, amputations and kidney failure) consistent with diabetes.

In India, over 30 million have been diagnosed with diabetes. The CPR (Crude Prevalence Rate) in the country’s urban areas is thought to be about nine per cent. In rural areas, the CPR is approximately three per cent of the total population. Another estimate says that the actual number of diabetics in India is around 40 million. As far as the pre-diabetic population is concerned, only China surpasses India, and by 2025,every fifth diabetic in the world will be an Indian.

IGT (Impaired Glucose Tolerance) is also a mounting problem in India. The prevalence of IGT is thought to be around 8.7 per cent in urban areas and 7.9 per cent in rural areas, although this estimate may be too high. It is thought that around 35 per cent of IGT sufferers go on to develop Type 2 diabetes. So, India is genuinely facing a healthcare crisis and the type of diabetes that its people suffer from differs considerably from what patients in the West suffer from.

Pre-diabetes currently refers to people who have impaired fasting glucose (IFG) i.e. fasting glucose levels between 100- 125mg/dl or impaired glucose tolerance (IGT), i.e. two hours post glucose load between 140-199mg/dl or both. Pre-diabetes raises short-term absolute risk of Type 2 diabetes five to six fold, and in some populations this maybe even higher.

As the prevalence of and progression to diabetes continues to increase, diabetes-related morbidity and mortality have emerged as major public health care issues.

People with diabetes are vulnerable to multiple and complex medical complications. These complications involve both cardiovascular disease (heart disease, stroke) and peripheral vascular disease) and microvascular disease.

Epidemiologic evidence suggests that these complications of diabetes begin early in the progression from normal glucose tolerance to frank diabetes.

Early identification and treatment of persons with pre-diabetic conditions has the potential to reduce both the incidence of diabetes and related cardiovascular and microvascular disease. Therefore, the following steps need to be considered:

Management of pre-diabetes:

The management of pre- diabetes involves a set of global treatment measures designed to address its abnormalities. The preferred treatment approach for all the abnormalities of persons in this group is intensive lifestyle management, given its safety and the strong evidence of efficacy of this approach in improving glycemia and reducing cardiovascular risk factors such as hypertension and Dyslipidemia.

Persons with pre- diabetes should reduce weight by 5-10 percent with long-term maintenance at this level. Even modest weight loss (seven to ten percent of body weight) results in decreased fat mass, blood pressure, glucose, low density lipoprotein, and triglyceride levels. These benefits can also translate into improved long-term outcome, especially if weight loss and lifestyle alterations are maintained.

A program of regular moderate-intensity physical activity for 30-60 minutes daily, at least five days a week is recommended.

The diet should be low in total, saturated fat and trans-fatty acids and with adequate dietary fiber. Specifically for blood pressure, lifestyle recommendations would include lower sodium intake and avoidance of excess alcohol.

Blood Pressure in pre-diabetes:

Pre-diabetic patients should achieve the same target blood pressure currently recommended for persons with diabetes, systolic 130 and diastolic 80mmHg.

Lipid goals in pre-diabetes:

Persons with pre- diabetes should achieve the same lipid goals as those with established diabetes i.e. cholestrol, non – HDL cholestrol, or apoB treatment goals of 100mg/dl, 130mg/dl, and 90mg/dl respectively.

Monitoring in pre-diabetes:

Monitoring of patients with pre diabetes to assess for worsening of glycemic status should include regular blood sugar test and testing for micro-albuminuria. Those patients at highest risk should be more carefully monitored. Fasting blood sugars, Glycosylated haemoglobin (index of sugar control in last three months) and lipid profile should be followed at least twice a year. If the results of monitoring reveal worsening hyperglycemia, intensified lifestyle and treatment with anti – diabetic medicines must be considered. (ANI)
