How to live till 100

Want to live till 100 years of age? Well, do regular exercises, be married, wash hands and brush your teeth everyday.
How to live till 100
That’s what a new book, ‘The Long Life Equation‘, by Dr Trisha Macnair suggests.
In the book, the author has listed activities that add years to your life.
Macnair said washing your hands adds two years, and good dental hygiene can add six more years in your life.
But smoking, fast food, no exercise and a stressful life can strip away 20 years.
“There’s no doubt younger people take life and health for granted – more than any generation before, they idle time away watching TV or playing computer games, ignoring the activities that keep them healthy or develop meaning in their lives,” Courier Mail quoted Macnair, as saying.
“As we get older and start to feel the years slipping away, we suddenly realise how precious it is.
“But by then we may have already established habits (smoking, drinking, obesity, lack of exercise, stressful occupations) which take their toll and are difficult to reverse.
“Still, it’s never too late to change. Also, our attitudes to older age are changing so there is more freedom now to do things later in life if we are healthy and able,” she added.
A 2006 study from University of California in Los Angeles showed that men and women live healthier, wealthier, happier and longer lives when they are in a stable partnership
The study confirmed that married couples were more likely to live to an old age than their divorced, widowed or unmarried counterparts.
A stable partnership can actually add on seven years to life.
Regular exercise also adds as much as two or more years to your life.
A Harvard Alumni Study, which took into account more than 71,000 men who had graduated from Harvard University and the University of Pennsylvania between 1916 and 1954, found that those men who regularly burned 8400kJ a week while exercising lived, on average, two years longer than sedentary types.
But cigarette smoking can actually reduce 8 years from your life
Tobacco smoke contains more than 4000 chemicals, many of which are highly toxic.
A divorce can also strip away 3 years from your life, as it takes longer-lasting, emotional and physical toll on former spouses than virtually any other life stress.
Recent studies indicate that divorced adults have higher rates of emotional disturbance, accidental death and death from heart disease.
The divorced also have higher rates of admission to psychiatric facilities and make more visits to doctors than people who are married, single or widowed.

Combined treatment protects kidneys

Joint control of blood pressure and blood glucose can cut down serious kidney complications by a third among patients with type 2 diabetes, says the findings of new research based on a study of 11,140 patients who were treated and followed for five years.
Diabetes mellitus, one of the greatest health threats, affect over 250 million people worldwide – a number estimated to rise to around 400 million by 2025.
Chief investigator John Chalmers of the George Institute for International Health, Australia, said: “The combination of routine blood pressure (BP) lowering and tighter glucose control confers very substantial benefits with reductions of one third for serious kidney disease, one quarter for cardiovascular death and close to one fifth for death from any cause.”
Previous findings showed that tight control of blood glucose with a regimen based on modified release of gliclazide, an oral anti-diabetic drug, reduced kidney complications.
Routine lowering of BP with the fixed combination of two drugs (perindopril and indapamide) cut down risk of death, as well as the risks of heart and kidney disease.
“These results provide powerful incentives for the millions of people living with type 2 diabetes,” Chalmers added.
The results were presented Monday at the European Association for the Study of Diabetes (EASD) conference in Rome.

Good bacteria has eczema on the run

A probiotic supplement, applied to the affected part, significantly halted eczema in infants under two, according to a study.
Good bacteria has eczema on the run
Researchers from Universities of Otago and Auckland investigated the use of two probiotic supplements in 446 mothers and babies.
Currently, there is no way to prevent eczema and treatment relies on skin moisturising and corticosteroid (anti-inflammatory) creams.
Probiotics are microbes found in infant gut which are beneficial to humans, but their dwindling numbers may explain the increasing incidence of eczema.
“Our study has found when you give probiotic supplement L. rhamnosus during the last five weeks of pregnancy, and for six months after birth while mothers are breast feeding, and then you give their infants the same probiotic up to two years of age, there is a 50 percent reduction in eczema,” said Julian Crane of Otago University, Wellington.
“This is an exciting and interesting result because we have compared the effect of two different probiotics in the same study and shown that one has an effect while the other is no different from a placebo.”
The study was published in the Journal of Allergy and Clinical Immunology. It found there was no similar preventive effect for eczema with the second probiotic, Bifidobacterium lactis.
Eczema affects 30 percent infants in New Zealand by the age of two. Severity varies from a small patch of scaly dry skin to large weeping areas covering much of a child’s body.

Depression remains undiagnosed in 50 percent of

aged

Clinical depression remains undiagnosed in half of the aged-care residents in nursing homes, according to a study by Deakin University School of Psychology.
Depression remains undiagnosed in 50 percent of aged
It found that 16.9 percent of residents in low-level care facilities who were mildly or moderately cognitively impaired suffered clinical depression. Less than half these cases had been detected or treated.
Cognitive impairment is severe mental retardation or inability to remember.
“This means that many people are leading a fairly miserable existence within the nursing home system,” Deakin professor Marita McCabe said.
“If they have undiagnosed depression they are more likely to withdraw and are more likely to experience physical symptoms such as disrupted sleep and appetite.”
McCabe said there was a general view that anyone who was in a nursing home would be depressed.
“There is a myth that depression is a normal part of ageing, but it isn’t,” she said. “Just because a person is getting older and they are in a nursing home, doesn’t mean they are going to be depressed.”
As a result of the study findings, Deakin has developed and implemented a training programme for staff at a number of Melbourne nursing homes.
“It is aimed at helping staff better recognise symptoms of depression and provides strategies they can undertake if they do recognise it,” McCabe said.

Research Centre (BHCRC) and three other institutions surveyed more than 1,400 adolescents and young adults between the ages of 15 and 21 who had unprotected sex in the previous 90 days. The findings will appear in the September/October issue of Public Health Reports.

“It’s clear that we have to address these attitudes, fears and concerns that many teens have regarding condom use, if we want to reduce their risk for contracting a sexually transmitted infection,” said co-author Larry K. Brown of BHCRC.
“The good news is that these attitudes may be easily influenced and changed through clinical and community-based interventions.”
Participants in Atlanta, Miami and Providence completed an audio computer-assisted interview to gather information about sexual risk behaviours including condom use within the previous 90 days.
Questions included attitudes and perceptions about condom use, and communication and negotiation with partners. The group included 797 females and 613 males. Approximately half were African American, 24 percent were Hispanic and 19 percent were white.
Nearly two-thirds of adolescents did not use a condom the last time they had sex. Participants also reported an average of two partners and about 15 incidents of unprotected sexual activity within the 90-day period.
Besides concerns about reduced sexual pleasure and partner disapproval, teens avoiding condoms use were also less likely to discuss them with partners. These findings held true across racial / ethnic groups, gender and geographic locations.

New blood test to confirm heart attacks within minutes

A new blood test will enable doctors to confirm heart attacks within minutes, instead of hours, prompting immediate treatment that could minimise damage to heart muscle
New blood test to confirm heart attacks within minutes
A study led by Massachusetts General Hospital (MGH) and Broad Institute of Harvard and MIT investigators reported a new technique that measures hundreds of molecular markers in the blood that can identify those released when cardiac tissue is injured by a lack of oxygen.
“Right now there are no blood markers for reversible myocardial injury (caused by a clot that stops blood flow in a heart artery) in clinical use, and the only available markers are not detectable until hours after the onset of tissue damage,” said the study’s co-author Robert Gerszten, from the MGH Division of Cardiology and Centre for Immunology and Inflammatory Diseases.
“Because our treatments for heart attacks are most effective in the first hours after symptoms occur, these newly identified markers could help us apply treatments sooner and help more patients,” Gerszten added.
The results of the study will appear in the October Journal of Clinical Investigation and has been released online.
Every metabolic activity in the body results in the production of metabolites, molecules released in very minute quantities. Hundreds of them are present in a blood sample that could provide a chemical snapshot of an individual’s health status.
But the technology to assess metabolite levels is in the early stages, as is the understanding of their significance. For instance, how much metabolite levels normally vary between healthy individuals and factors that influence those variations is still unknown.

Drug abuse goes up in developing world

The developing countries have seen a phenomenal rise in the use of stimulant and ecstasy drugs while their use in the developed world has decreased significantly, according to a report of the United Nations Office on Drugs and Crime (UNODC).
Drug abuse goes up in developing world
Argentina in Latin America has become the largest consumer of these drugs with Brazil taking second place, the report said.
In Argentina consumption reached 17 daily doses for every 1,000 residents in the same period, it said, adding that in Brazil, consumption of amphetamines (ATS), methamphetamines and ecstasy was 10 daily doses for every 1,000 residents from 2004 to 2006.
The report said the global consumption of ATS has surpassed cocaine and heroine. The ATS retail market is valued at about $65 billion.
The report also said ATS consumption seems to have stabilised or even declined in developed countries, but is seeing an increase in developing countries.
Asia is responsible for over half of the demand for ATS in the world. Half of Asian countries registered an increase in ATS consumption in recent years, according to the report.

Knee surgery for arthritis is ineffective: study

A new Canadian study shows that the popular knee surgery for arthritis is actually ineffective in reducing joint pain or improving joint function.
Knee surgery for arthritis is ineffective: study
Arthroscopic surgery, currently considered an effective treatment for osteoarthritis of the knee, is performed for inserting an arthroscope and other instruments into the joint to remove cartilage fragments and smoothen the joint surfaces.
But a landmark study by the University of Western Ontario at Waterloo near here, and the Lawson Health Research Institute, about 200 km from here, shows that arthroscopic surgery has no additional benefits for patients.
“This study provides definitive evidence that arthroscopic surgery provides no additional therapeutic value when added to physical therapy and medication for patients with moderate osteoarthritis of the knee,” said study co-author Brian Feagan of the University of Western Ontario.
As part of their eight-year-long study, which ran from 1999 to 2007, researchers – orthopaedic surgeons, rheumatologists, and physiotherapists – subjected 178 men and women – with an average age of 60 – to two different treatments.
While all participants received physical therapy as well as medications, including ibuprofen or acetaminophen, only 86 of the patients also received surgery consisting of lavage and arthroscopic debridement.
At intervals after the treatment, the researchers found that both groups experienced comparable improvements in joint pain, stiffness, and function, but surgery provided no additional benefit.
The research confirms the similar results of another study in 2002 which was dismissed by the medical community.
However, study co-author Bob Litchfield was quick to add, “Although this study did not show a significant therapeutic benefit of arthroscopic debridement in this patient population, knee arthroscopy is still beneficial in many other conditions affecting the knee, such as meniscal repair and resection, and ligament reconstruction.
“As surgeons, we need to know when things are working and when they’re not. If this particular technique is not working for this subgroup of patients, we better come up with something else that does.”
Osteoarthritis is the most common form of arthritis affecting 3.3 million Canadians and 27 million Americans.
The study appears in this week’s issue of New England Journal of Medicine.

CIH.

The mice were evaluated on a series of complex sexual behaviours, including erection frequency and mating behaviour and biomarkers that may be affected by CIH, like testosterone and estradiol levels.
After just five weeks exposure to CIH, the gap between mounting times increased 60-fold. The potential to ejaculate was also severely affected.
In five out of seven mice tested, ejaculation did not occur at all, but in one mouse, gap between ejaculations was 11 hours whereas in control mice the median time was “only a few minutes, said Gozal. Interestingly, one mouse appeared to be unaffected in this respect.
“The disparity in responses among mice is very similar to the heterogeneity of the magnitude of end-organ morbidity in sleep apnea among patients, and shows that not everyone will be affected to the same extent,” said Gozal.
Even after six weeks’ recovery time with standard oxygen levels, mice exposed to CIH for as little as one week only recovered 74 percent of their original erectile function, wrote Gozal. The results appeared in the September edition of the American Journal of Respiratory and Critical Care Medicine.
Despite the lingering negative effects of CIH on sexual behaviour in mice, the researchers did find that it was largely reversible. In the second phase of the experiment, Gozal administered tadalafil, which improved erectile and sexual functioning in CIH-exposed mice to near-normal levels in almost all cases.

‘Sleep disorder suppresses sex drive’

A diminished sex drive may be linked with chronic oxygen deprivation in patients of obstructive sleep apnea, especially during episodes of obstructed breathing.
Washington: University of Louisville (U-L) researchers have found that after a week of being subjected to chronic oxygen deprivation (CIH), mice showed a 55 percent decline in their daily spontaneous erections. After five weeks of such exposure, average interval between mounting a mate increased 60-fold.
“Even relatively short periods of CIH are associated with significant effects on sexual activity and erectile function,” wrote David Gozal, professor of paediatrics at the U-L.
The study examined the behavioural and physiological effects in mice exposed to CIH for anywhere from five to 24 weeks. Control mice were kept under identical conditions, but were not subjected to nocturnal CIH.
The mice were evaluated on a series of complex sexual behaviours, including erection frequency and mating behaviour and biomarkers that may be affected by CIH, like testosterone and estradiol levels.
After just five weeks exposure to CIH, the gap between mounting times increased 60-fold. The potential to ejaculate was also severely affected.
