Genes that control share of carcass riches are also responsible on circulating levels of testosterone in men, experiment with published in the latest version of Clinical Endocrinology shows. The enquiry shows a 23% overlap between the genes that device testosterone and those that regulate trunk fat composition, suggesting that these two variables are partly controlled by the very inhibit a write down of genes.

The study led by Dr Jean-Marc Kaufman at Ghent University Hospital, Belgium was carried out on healthy male sibling pairs and estimated the extent to which sex hormones and body fat are controlled by the same genes. The research involved a cohort of 674 men from 274 independent families, as part of a larger study investigating the origins of body composition, sex steroid status and peak bone mass in healthy men. Each participant had their weight, total body fat and BMI measured and a blood sample was taken to measure their levels of testosterone and SHBG (a protein that binds to sex hormones). The team then used two computer programs (SAGE and SOLAR 2.0) to carry out complex statistical modelling to calculate the ‘heritability estimate’ of each trait, that is, the extent to which each characteristic is influenced by genes (as opposed to environmental factors). The correlation between two different variables (e.g. testosterone and body fat) was then calculated, based on their individual heritability estimates.

A strong correlation was found between sex hormones and body fat, which was predominantly due to shared genes. Specifically, testosterone and SHBG both showed a 23% genetic correlation with body fat, and SHBG showed a 29% link with whole body fat. There was no link in terms of environmental factors between sex hormones and body composition.

When measured individually, testosterone had the highest heritability estimate of the sex hormones at 0.65 (heritability estimates are measured on a scale between 0 and 1, with 1 equalling 100% genetic influence). SHBG, weight and body fat also had high heritability estimates of 0.73, 0.83 and 0.65, respectively. Such high heritability values are similar to those previously published1, and indicate that circulating testosterone levels are approximately 60% influenced by genes.

Previous studies have shown a well-established relationship between testosterone and body fat composition. For example, men with low testosterone levels are characterised by a high body fat percentage. However, despite this well documented link, the causal factors behind this relationship have remained unknown. In this study, the authors show the set of genes that control testosterone levels also control body fat, providing for the first time an underlying causal link to explain this relationship.

Researcher Dr Jean-Marc Kaufman said:

“Body fat composition is influenced by environmental factors such as diet and exercise, but is also strongly controlled by genes. There is a well-established relationship between testosterone and body fat composition, which we have now shown is a result of shared genetic regulation. We know that testosterone and body fat show high degrees of heritability as individual traits, but in our cohort of young men we showed that they are partially controlled by the same set of genes. Our results help to explain the complex interplay between fat mass and sex hormones. Further research is now needed to investigate the individual genes that control sex hormone levels and body composition, which could provide further insight into the regulation of testosterone levels and testosterone sensitivity in men. “

Background information

Testosterone is the principal male sex hormone, and is required for sperm production, development of male reproductive organs and appearance of secondary male sexual characteristics. SHBG is a transporter protein that binds to sex hormones such as testosterone in the bloodstream. Only a small fraction of circulating testosterone is free (and therefore biologically active), as the majority is bound to SHBG and therefore inactive. When measuring testosterone concentrations in the blood, ‘free’ testosterone is calculated from total testosterone and SHBG levels.

Diabetes may significantly increase the risk of developing Alzheimer’s, a study of 824 nuns, priests, and Eclectic brothers, found bolstering evidence linking the two diseases.

Participants studied were 55 and older when the research began and were followed on ordinary almost six years.

Alzheimer’s developed in 151 participants, including 31 who had diabetes.

The researchers calculated that diabetics faced a 65 per cent higher peril of developing the attention-robbing bug.

The link remained strong, even when researchers factored in the prevalence of strokes - a common complication of diabetes - which are also believed to evoke the hazard of Alzheimer’s.

Previous dig into has linked diabetes with memory problems and diabetes is known to damage blood vessels that supply the brain.

“This is a man of the first long-denominate studies to follow people who start distant with no evidence of Alzheimer’s disease and footprints how having diabetes affects their risk of developing it,” said William Thies, an Alzheimer’s Association vice-president. “It’s a powerful argument for doing the whole shooting match you can to control your blood sugar.”

The pre-eminent step towards producing a European prototype of a swine flu vaccine has been achieved by the Health Protection Agency (HPA), Constitution Secretary Alan Johnson has announced. On a by to the HPA’s National Institute of Biological Standards and Control (NIBSC) this morning, Alan Johnson learnt that researchers beget sequenced the full genetic unwritten law’ of the virus. This is critical in understanding how the virus operates and identifying the crucial parts of the virus that can be tempered to in vaccine manufacture.

Researchers hope that European manufacturers will be able to take delivery of candidate vaccine prototypes in the coming months so preliminary steps to mob vaccine play can begin.

The NIBSC is the merely middle in the UK and one of a handful around the world developing vaccine prototypes for the European vaccine manufacturers. In the US, efforts are focused through the Centre for Disease Subdue.

In July 2007, the Government signed advanced purvey agreements, which will license the UK to purchase up to 132 million doses of pandemic definite vaccine, when it becomes available. The advanced supply agreements are worth £155.4 million over four years. Under these contracts, GSK and Baxter are committed to supplying a pandemic influenza vaccine as soon as the pandemic strain is identified and made accessible by the World Health Organization.

The HPA researchers will also work with sister organisations to compare the characteristics of this virus with other samples to gain a greater understanding of how flu infects people and how it can quickly change to weasel out of our untouched systems.

Constitution Secretary Alan Johnson said:

“A significant action towards protecting the world’s health against swine flu has been charmed. The step on it with which vaccine prototypes can be created to combat potential pandemics is claim to the dedication and world-excellence expertise of Robustness Protection Operation researchers. We have been preparing suitable the possibility of a pandemic for some sometime. We just now look to the vaccine perseverance to put the required quantities of vaccine as straight away as possible.”

Professor Maria Zambon, Maestro of the Health Safe keeping Agency’s Centre throughout Infections, said:

“We are continuing to learn more and more each day more swine flu. The sinless cross-section of virus that we have eremitical, together with its genetic fingerprint, will be important resources as scientific organisations join forces on the development of an effective vaccine. The rapid assessment of this virus will after all is said help us to make approaching decisions regarding the health implications of swine flu.”

Ends

1. The Department of Form has mark off up a dedicated swine flu information line for the public: 0800 1 513 513.

2. Under these advanced supply contracts, the Control of Health has cool production capacity for the mass production of the new vaccine and making an investment in R&D by the manufacturers. This means that although the UK may not express delivery of vaccine until after a pandemic has started, it will notwithstanding have a guaranteed provide of vaccine at a time when there will be historic universal demand. For the vaccine to be fully effective, an individual is likely to necessity two doses.

3. Pandemic distinct vaccines will not be available until 4-6 months after a pandemic virus has emerged and hence it may be of limited licence in the first undulation of a pandemic. It is no doubt to be over a year preceding the time when all of the vaccine has been delivered. It cannot be known in advance whether a pandemic will maintain chestnut or more waves.

4. The World Salubrity Organization (WHO) has raised its pandemic alert straight-shooting to Aspect 5. ‘This is characterised by human-to-lenient spread of the virus into at least two countries in one WHO district. While most countries will not be affected at this stage, the declaration of Phase 5 is a strong signal that pandemic is imminent and that the time to finalise the organisation, communication and implementation of the planned mitigation measures is short’. The Agency is proper prepared to meet the requirements of phase

Smoking tobacco is no longer considered sexy, but it may prove a persistent turn on for some genes.

Research published in the online open access journal BMC Genomics could help explain why former smokers are still more susceptible to lung cancer than those who have never smoked.

A Canadian team led by Wan L Lam and Stephen Lam from the BC Cancer Agency, took samples from the lungs of 24 current and former smokers, as well as from non-smokers who have never smoked. They used these lung samples to create libraries using a technique called serial analysis of gene expression (SAGE), which helps to identify patterns of gene activity.

Only about a fifth of the genes in a cell are switched on at any given time, but environmental changes such as smoking lead to changes in gene activity. The researchers found changes that were irreversible, and some changes that were reversed by stopping smoking. The reversible genes were particularly involved in xenobiotic functions (managing chemicals not produced in the body), nucleotide metabolism and mucus secretion. Some DNA repair genes are irreversibly damaged by smoking, and smoking also switched off genes that help combat lung cancer development.

The researchers identified a number of genes not previously associated with smoking that are switched on in active smokers. One example is CABYR, a gene involved in helping sperm to swim and associated with brain tumours, which may have a ciliary function. The team also further investigated changes in genes involved in airway repair and regeneration, and within this group identified genes that fell into three categories following cessation of smoking: reversible (TFF3, encoding a structural component of mucus; CABYR, in it’s newly discovered bronchial role), partially reversible (MUC5AC, a mucin gene) and irreversible (GSK3B, involved in COX2 regulation). These findings were tested against a second cohort of current, former and non-smokers.

“Those genes and functions which do not revert to normal levels upon smoking cessation may provide insight into why former smokers still maintain a risk of developing lung cancer,” according to Raj Chari, first author of the study. The study is the largest human SAGE study reported to date, and also generated a large SAGE library for future research.

Tobacco smoking accounts for 85 percent of lung cancers, and former smokers account for half of those newly diagnosed with the disease.

The political impel to piece of equipment the NHS’s national programme as a replacement for word technology is defect to take account of professionals’ anxieties, argues a GP in this week’s BMJ.

Dr Nigel de Kare-Silver describes his experience of workshops to introduce the new system to users. “We were shown screens of a third rate computer program lifted from the existing system of US hospital administrators,” while further meetings produced “lame presentations by various strategic health authority IT leaders.”

He goes on to describe problems with the “choose and book” system, in which doctors will select from a list of local hospitals and book an appointment while the patient waits. This has a national implementation date of the end of December 2005.

“The application screens are slow, and the computers often fail to pick up the programs. There is no integration with existing clinical systems or with Microsoft Outlook,” he writes.

But the “really frightening module” is the inability of the software to retain advice by either the consultant or the GP, or to integrate it with clinical results. “This is a major clinical governance issue, he adds.

While the ambition of the NHS agenda for IT change should be applauded, it is unfortunate that the contractors show no ability to deliver a system that is an advance on existing services, says the author. “It is frightening that the political drive to implement the system is failing to take account of professionals’ anxieties.”

Before allowing its delivery, clinicians from all backgrounds must demand a service that is rigorous in terms of clinical governance, friendly in its user interface, fast, and relevant to the needs of clinicians and patients, he concludes.

Japanese encephalitis energy be more widespread in Indonesia than previously thought. In a study published today in the open access logbook BMC Medicine (http://www.biomedcentral.com/bmcmed/), researchers analysed the frequency toll of Japanese encephalitis, a potentially deadly disability caused by a mosquito-borne virus, in children living on the Indonesian atoll of Bali. The researchers found an degree rate of 8.2 per 100,000 in children less than 10 years old. They conclude that contrary to previous findings, which were probably due to incomplete surveillance, the disease is widespread in Bali. Better scrutiny and the implementation of vaccination programmes seeking Japanese encephalitis are needed in Bali.

Komang Kari from Udyana Univeristy School of Medicament in Bali, Indonesia, and colleagues from other institutions in Bali, Korea and Thailand studied 239 Balinese children who reported to salubrity centres or clinics with symptoms similar to those of Japanese encephalitis, between July 2001 and December 2003.

Kari et al. confirmed that 86 in of the 239 children had Japanese encephalitis and that a push four children probably had the disease - the virus was only detected in their serum and not in their cerebrospinal fluid. Of these 90 children, only one was over 10 years ramshackle. Of the children with confirmed Japanese encephalitis, nine died and 31 were liberal with serious neurological disability. The authors conclude that the annual incidence rate for children under 10 is 8.2 per 100,000.

Perception PMS

PMS or premenstrual syndrome is a term that is used to refer to the collective disorder that a woman feels in relation to her menstrual cycle. These disorders may be physical, psychological, and emotional or a combination of them. Although women in general suffer from one or more disorder in relation to menstruation, the term qualifies that the disorder must be so severe so as to disrupt the regular patterns of life. As such, some disorders experienced by women, despite being associated with menstruation, cannot be strictly defined as PMS. Presently, experts contend that only a very small fraction of the female population suffers from PMS. However, regardless of how small the number of women affected may be, a solution should be offered to help women cope better with the situation.

Natural Approaches in Treating PMS

Despite the prevalence of medication and other forms of treatment for treating PMS, most women prefer a natural solution because it has no known side effects to the body. When it comes to natural solutions to PMS, the following approaches should be tried:

*Dietary method. Here, it means that the woman needs to take certain nutrients to help counter PMS. The most common nutrient that is believed to hold benefits in treating PMS is calcium. Calcium may be obtained from fruits such as citrus and other vegetables. However, there are now available calcium supplements on the market purported to be made from fruit or vegetable extracts, emphasizing their natural source. Another vitamin that is also helpful in treating PMS is vitamin E. It is also recommended that one increase the intake of fiber. This is because fiber is known to help the body flush out harmful elements that may impede menstrual flow and cause severe pain to the woman. *Exercise and physical activity. Because PMS is associated with menstruation and menstruation becomes painful in the absence of physical activities, regular exercise is recommended to help lighten the onset of menstruation by reducing physical pain. Exercise need not be exhaustive. All that is needed is a short walk or a light jog, as long as it is done regularly. * Enough rest and sleep. Deprivation of rest in women is a very harmful situation. Not only does it contribute to the onset of PMS, it also paves the way for other ailments as well. * Change in lifestyle. Some women may be into smoking and drinking as well as taking drugs. Continuation of these practices can be the culprit of PMS as these habits expose the body to severe stress and changes that do no good at all. * Reduction of caffeine and sugar intake. * Psychological counseling. Although this is a form of intervention, counseling helps in most women because it gives them a feeling of self-reassurance. Moreover, it helps women to counter the negative thoughts that may arise from one’s unpleasant experience with PMS. It also helps the woman develop a more positive outlook despite the condition.

A simple points process may in short order cure guide treatment of elderly heart default patients. Researchers at Washington University School of Cure-all in St. Louis found that by counting how multitudinous of seven simple-to-obtain health factors a persistent has, physicians can estimate the patient’s gamble of in extremis.

The points system may steer doctors toward making allowance for more aggressive treatments such as implantable defibrillators and pacemakers in regard to those at depressed chance of extermination. However, superannuated patients with a high risk may scarcity to steer clear of stressful and unnecessary medical intervention and may benefit most from palliative or hospice care.

“It has typically been very unmanageable to presage how long a person hospitalized with heart failure may live on,” says older prime mover Michael W. Rich, M.D., associate professor of medicine and a geriatric cardiologist at Barnes-Jewish Sickbay. “That has made it ill poor for the treating physician to know how assertive to be with therapy.”

Heart failure afflicts about 5 million people in the Of one mind States, hospitalizing more than a million patients each year. The quantity of heart failure increases with stage, and with people 65 and older meet the fastest growing segment of the population, the personal and financial burden of crux nonentity command likely increase.

In their meditate on, which followed 282 elderly heart collapse patients fit up to 14 years, the researchers identified seven factors that most put on patient survival:

* advanced age

* a background of dementia (contributes to a host of conditions related to the ineptness to properly care for oneself)

* coronary artery disease (arteries that contribute blood to the soul muscle are hardened and narrowed)

impotencia

* minor vascular affliction (similar to coronary artery disease but involving blood vessels exterior of the heart and brain)

* low sodium in the blood (an indication of neurohormonal imbalance)

* tipsy urea in the blood (a reflection of pitiful cardiac achievement that affects kidney function)

* vulgar blood pressure (a result of weakened heart function).

The ponder, published in the September 25th issue of the Archives of Internal Nostrum, showed that patients with four or more of the peril factors had a moo probability of surviving longer than six months. But if patients had none or unbiased one of the factors, they had a good chance of living five years or more. Patients with two to three factors were likely to white-hot at least a year. The patients in the study received a variety of treatments as determined by their physicians.

“The process is easy to pour down the drain, and the variables don’t need any specialized testing — they are part of routine medical histories or central lab tests,” Profitable says. “If the modus operandi can be validated by further studies, it can play a responsibility in portion physicians tailor care to lone patients. If a person has a limited life expectancy, it may not be in his or her overcome interest to recommend invasive, uncomfortable or dicey procedures. On the other hand, an old fogies person with no more than one endanger factor could potentially be considered a good candidate in favour of an aggressive treatment such as a defibrillator.”

Other factors that might take been expected to affect survival, such as the amount of blood the enthusiasm can eject during pumping or a patient’s body gather typography hand, didn’t seem to alter survival times. Amusing emphasizes that each of the factors identified has been linked in previous studies to poor prognosis in heart failure patients.

“We didn’t consider any new chance factors, which means there’s good data to weather that these factors accurately are predictive,” Well off says. “We’ve pinpointed the seven that are the most predictive and shown that the number of risk factors can give a reasonable estimate of the odds of living for six, 12 or 60 months.”

The researchers next focus to better sort out the heart lemon patients not likely to survive six months so that they can be referred for hospice regard.

“Hospice is very nurturing allowing for regarding both patients and family members,” Rich says. “There is largish prove that patients derive valued benefit from it. If we can predict mortality within six months, we can more undoubtedly establish eligibility for hospice care.”
