The review of the antiviral drug Tamiflu has cast doubts on its usefulness in preventing serious illness, and led to accusations that manufacturer Roche withheld trial data from researchers.

Roche yesterday stood by Tamiflu, which was widely used during this year’s swine flu pandemic, saying its safety and efficacy had been well established. Experts say the review raises questions about the entire system by which drugs are evaluated, regulated and promoted, because it relies on data created and held by drug companies.

The Cochrane review, published in the British Medical Journal yesterday and led by Professor Chris Del Mar from Bond University in Queensland, looked at all evidence on the effectiveness of antiviral drugs.There was no reliable evidence that the drug could ward off hospital admission or complications such as pneumonia or bronchitis - counter to previous claims.

It concluded Tamiflu had a ”modest” effect on flu symptoms, reducing the length of illness by one day. ”We believe [antivirals] should not be used in routine control of seasonal influenza,” it said, and it was unable to give a confident recommendation about use in a pandemic. The authors of the new review said these factors left the trials ”at risk of bias”, and they had been unable to independently confirm their conclusions because Roche had not provided the raw data.

”Governments around the world have spent billions of pounds on a drug that the scientific community now finds itself unable to judge,” said Dr Fiona Godlee, editor of the British Medical Journal.

Self confidence requires a positive self-image. Self-image is a kind of mental picture we all have about ourselves. One way to think about self-image is in terms of what is ‘real’ and what is ‘ideal’.Good self confidence is the sign of the autonomous individual who believes in himself and is ready to take any challenge in the life. The way you think about yourself has an enormous impact on how others perceive you. If you feel confident about yourself then even people will show confidence in you. Problems can occur when people strive too hard to fit with their ideal view of self-image and this can mean they underplay their actual characteristics. The nice guy then finds it hard to reprimand people when they under-perform and the strict guy maybe fails to listen to others and reward opinions different to their own.

Thus to help all such focus, here are some simple ways through which you can boost self confidence.

Self Image:
Self-image is the mental picture you have of yourself. It is not fixed, it is not objective, it can be changed and you can change it. While you attempt at anything for the very first time, feel as if you have a lot of experience in it. Imagine that you have been largely successful when you go for it for the first time. Our brain does not know how to distinguish between imagination and reality. Hence if you make you imagination vivid, you will increase your chances of succeeding.

Self Analysis:
The self analysis process will let you know about your fears. So, the next step would be to conquer your fears. Once you overcome your fears then your self confidence will improve and you will believe in yourself. If you are really afraid of anything, try out that thing. This will help you to see the warrior in your personality and your ability to perform would be enhanced.

Behavior:
Changing behavior is often easier than changing thinking. The brain does not deal well in turning around negative thinking. For example, the moment you think, ‘I must not be nervous’ is the moment you will actually start feeling more nervous. Focusing on behavior when you are nervous, such as breathing deeply and slowly and relaxing neck and shoulder muscles, will do a great deal more than ruminating on your anxiety.

Learn to overcome failures:
This property is very important and may boost your self confidence if you learn it. Failures are the first step towards the success so take them gradually. You will also enhance your other required qualities and may overcome your drawbacks that will certainly give a boost to your self confidence.

Accept truth:
If you are not able to do something just say no. Don’t think above the expectations. Just analyze the situation more objectively and try to find the realistic solution.

Positive thinking:
Positive thinking is important but the way you behave is important too. Your self-image will feed off the way you behave and will affect others too. Actors know that if they have to play a sad role they quickly start to feel sad themselves. Similarly, if you speak in a measured slow tone your authority increases to those around you and you actually start to feel it in yourself.

Therefore, follow these simple tips and your self confidence would be improved.

Sexuality can be embarrassing for many people to discuss. The same goes for urinary incontinence. So it can be doubly difficult to address when incontinence gets in the way of a satisfying sex life.

What Is Urinary Incontinence ?

Urinary incontinence is loss of bladder control. Symptoms can range from mild leaking to uncontrollable wetting. It can happen to anyone, but it becomes more common with ageMost bladder control problems happen when muscles are too weak or too active. This is stress incontinence. If bladder muscles become too active, you may feel a strong urge to go to the bathroom when you have little urine in your bladder. There are other causes of incontinence, such as prostate problems and nerve damage.Millions of adults in the United States have urinary incontinence. It’s most common in people over 50 years old, especially women. But it can also affect younger people, especially women who have just given birth.

Incontinence and Sex Problems:

Studies have found that many women with incontinence report the same amount of sexual activity as women without incontinence, and that they enjoy the sex just as much.People who have stress incontinence usually can tell when during intercourse they are most likely to leak. But urge incontinence occurs unpredictably, making it difficult for the person to fully enjoy sex. The chance of embarrassment is also greater — much more urine leaks during an episode of urge incontinence compared with stress incontinence, and women with urge incontinence often leak during orgasm.

Causes of urinary incontinence:

• For men, enlarged prostate gland or prostate surgery

• For women, thinning and drying of the skin in the vagina or urethra, especially after menopause

• Overweight and obesity, which increases pressure on the bladder and muscles that control the bladder

• Diseases such as diabetes, Alzheimer’s disease and multiple sclerosis

• Weakened and stretched pelvic muscles after childbirth

• Vascular disease

How to Avoid Incontinence while having sex:

Exercises regularly:

Studies have shown that women who do Kegels on a regular basis suffer less leakage during sex.

Electrical stimulation.

In this procedure, electrodes are temporarily inserted into your rectum or vagina to stimulate and strengthen pelvic floor muscles. Gentle electrical stimulation can be effective for stress incontinence and urge incontinence, but it takes several months and multiple treatments to work.

Choose your sexual position wisely

Certain positions make incontinence less likely. A woman on top can better control her pelvic muscles and the stress caused by penetration. Side intercourse can be less strenuous.

Limit fluid intake prior to sex

Avoid drinking anything for about an hour before you think you’ll have sex. You also should go to the bathroom just before sex.

Talk to your doctor

Don’t be afraid to tell your doctor about your incontinence problem, or about its effect on your sex life. Your physician will be able to help treat your incontinence, give you practical advice, and possibly refer you to a specialist.
