New Delhi, Feb 9: Winter problems are no longer restricted to cough, cold and flu. When the temperature drops and the cold winds begin to blow, the air becomes drier and our bodies get less moisture than they do in warmer months, leading to dehydration. And that is the first step towards a Urinary Tract Infection (UTI).

urinaryUTI refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra and one tends to be exposed to such infections in winters.

Dr. Anant Kumar, Chairman - Urology, Renal Transplant, Robotics, and Uro-Oncology Max Super Speciality Hospital, Saket said, " Our bodies suffer from UTI in winters as we stop drinking water. While we can invest in any warm beverage rather than icy water when it comes to wintertime, it's still critical to maintain the water intake. Consumption of less water, especially during winter is one of the main causes that worsen UTI."

Moreover, the main symptom of the infection which is burning sensation is usually considered a result of eating high calorie rich food during this season. This delays the patients from approaching the doctors on time. Also, women who make contact with the infections are so apprehensive of reporting it to the doctors that they prefer to self-medicate, which in turn makes the infection acute.

While most cases of bladder infection occur suddenly, others may recur over the long-term. Early treatment is keys to preventing the spread of the infection. Bacteria that enter through the urethra and travel into the bladder cause bladder infections. Normally, the body removes the bacteria by flushing them out during urination. This overwhelms the body's ability to destroy them, resulting in a bladder infection.

According to Dr. Kumar, for preventing bladder infections the following lifestyle changes may help reduce or eliminate the occurrence of bladder infections:

• Change underwear daily: Since women are more prone to infections, they should change their undergarments twice a day.

• Don't hold urine: Urinate as soon as you feel the need. Holding urine for long multiplies the bacteria, thus causes infection.

• Wear cotton underwear: Cotton underwear's are comfortable, especially for women as it helps keep the vagina dry. Synthetic underwear's cause excessive friction, thus leading to discharge of fluid which causes irritability

• Don't Use feminine hygiene sprays: The pH in the vagina regulates itself, and douching or spraying, changes the equilibrium.

• Urinate before and after sexual activity: Urinating right after sex can help prevent the spread of faecal bacteria to the bladder and thus reduce the risk of UTIs. Men should pass urine each time after the sexual intercourse.

Here are the five most effective bladder infection remedies:

• Drink more water: Have at least 2 litres of water every day. Water flushes out the bacteria in your bladder, helping to eliminate the infection faster. It also dilutes your urine, so urination may be less painful.

• Antibiotics: Antibiotics kill the bacteria causing the bladder infection. Antibiotics may not always be needed. In some cases, a minor bladder infection can resolve on its own. It might cause symptoms for a day or two, but with increased hydration and urination, it may pass.

• Heating pads: Putting low heat across your abdominal region or back may soothe the dull ache that sometimes occurs during bladder infections. This can be especially helpful if medications aren't enough to ease your discomfort.

• Appropriate dress: Bacteria thrive in warm and moist environments.

Tight jeans and other snugly fitting clothes can trap moisture in your most delicate areas, making them a breeding ground for bacteria. Wearing loose, casual clothing that allows your skin to breathe can keep the bacteria in your urinary tract at bay.

Feb 26: While too much stress can be toxic to your health, a new study suggests that despite its negative side effects, it may also lead to a surprising social benefit.

The research, published in the journal Stress & Health, found that experiencing stress made people both more likely to give and receive emotional support from another person.

This was true on the day they experienced the stressor as well as the following day.

"Our findings suggest that just because we have a bad day, that doesn't mean it has to be completely unhealthy," said study researcher David Almeida from Penn State University in the US.

"If stress can actually connect us with other people, which I think is absolutely vital to the human experience, I think that's a benefit. Stress could potentially help people deal with negative situations by driving them to be with other people," Almeida added.

For the study, the researchers interviewed 1,622 participants every night for eight nights. They asked the participants about their stressors and whether they gave or received emotional support on that day.

Stressors included arguments, stressful events at work or school, and stressful events at home.

The researchers found that on average, participants were more than twice as likely to either give or receive emotional support on days they experienced a stressor.

Additionally, they were 26 per cent more likely to give or receive support the following day.

The researchers said that while this effect, on average, was found across the participants, it differed slightly between men and women.

"Women tended to engage in more giving and receiving emotional support than men," said study researcher Hye Won Chai.

"In our study, men were also more likely to engage in emotional support on days they were stressed, but to a lesser extent than women," Chai added.

The researchers said they were surprised that stress was linked to people not just receiving emotional support, but giving it, as well.

"We saw that someone experiencing a stressor today actually predicted them giving emotional support the next day," Almeida said.

"This made me think that it's actually possible that stress helps to drive you to other people and allows it to be ok to talk about problems -- your problems, my problems," Almeida added.

Being overweight or obese is now recognised as a serious cause of ill health and disability. There is a significant positive association between orthopaedic disorders and the level of obesity causing pain, deformity and difficulty in walking.

Excess body weight accumulation increases pressure on joints, particularly the hips, knees and ankles.

Here are a few type of  arthritis:

Osteoarthritis

It is a condition of damage/ wear and tear of the joint lining or cartilage. Obesity triggers this by loading excessive weight on the weight bearing joints like the knee and the hip. 

Knee Osteoarthritis

This is the most common arthritis especially in the Indian subcontinent.

While walking, an individual exerts 3 to 6 times pressure that of the body weight on the weight-bearing knee joint, which means in an obese with excess body weight, larger forces are exerted, which lead to higher risk of deterioration of cartilage.

In addition, there are excessive fat tissues that produce hormones and other factors that affect the joint cartilage metabolism and cause inflammation of the joints giving rise to joint pathology.  Leptin is one of the hormones causing knee osteoarthritis. 

Hip osteoarthritis

The force exerted across the hip is 3 times that of body weight. Hip osteoarthritis is caused by factors such as joint injury, increasing age and being overweight.    

Hand osteoarthritis

The observation that obese individual has a higher risk in having hand osteoarthritis has led to a hypothesis that the metabolic effect produced by fat tissue is the underlying factor. 

Osteoporosis

It is a progressive bone condition of decrease in bone mass and density (Bone Mineral Density or BMD) which can lead to an increased risk of fracture. Recent research suggests that obesity may accelerate bone loss. It is the amount of muscle mass which is seen in an active person, which accounts for bone strengthening effects and not due to the fat seen in a heavy person.

Low back pain

Low back pain from degenerative disc disease of the lumbar spine is one of the most disabling conditions in the community and overweight and obesity have the strongest association with seeking care for low back pain.

Managing Hip and Knee Osteoarthritis

Life style changes

If one is overweight, try to lose weight by doing more physical activity and eating a healthier diet. Regular exercise keeps you active and mobile and builds up muscle, thereby strengthening the joints and can improve symptoms. 

Pain Killers

Painkillers help with pain and stiffness for short term. They don’t affect the arthritis itself and won’t repair the damage to your joint. Creams and gels can be applied directly onto painful joints.

Nutritional Supplements

Glucosamine and chondroitin are nutritional supplements. Animal studies have found that glucosamine can both delay the breakdown of and repair damaged cartilage. However, there is insufficient evidence to support the use of glucosamine in humans and one can expect only a mild-to-moderate reduction in pain

Joint injections

If pain from osteoarthritis is severe joint steroid injections are injected into the joints that can reduces swelling and pain. The injections can start working within a day or so and may improve pain for several weeks or months. 

Hyaluronic acid injections, which help to lubricate your knee joint also give short term relief. In early stages. Stem cell treatment or cartilage regeneration procedures are being tried in young people with small defects, however it is still experimental and lacks long term evidence.

Surgery

May be recommended if you have severe pain or mobility problems.

Arthroscopy

If one has frequent painful locking/stiffening episodes especially in the knee joint, an operation to wash out loose fragments of bone and other tissue as joint can be performed by a minimally invasive key hole procedure called Arthroscopy.

Arthrodesis

If hip or knee replacement is not suitable, especially in young people who do heavy manual work, one can consider an operation known as an arthrodesis, which fuses your joint in a permanent position. This means that your joint will be stronger and much less painful, although you will no longer be able to move it.

Osteotomy

In young, active people in whom a knee joint replacement would fail due to excessive use one can consider an operation called an osteotomy. This involves adding or removing a small section of bone either above or below your knee joint.  This helps realign your knee so your weight is no longer focused on the damaged part of your knee. An osteotomy can relieve your symptoms of osteoarthritis, although you may still need knee replacement surgery eventually as you grow old

Joint replacement surgery

Joint replacement therapy is most commonly carried out to replace hip and knee joints. It involves replacing a damaged, worn or diseased joint with an artificial joint made of special plastics and metal.

For most people, a replacement hip or knee will last for at least 20 years, especially if it is cared for properly and not put under too much strain.

Early treatment with the antiviral drug remdesivir has been found to reduce viral load and prevent lung disease in macaques infected with SARS-CoV-2 that causes COVID-19, according to a study.

The findings, published in the journal Nature on Tuesday, support the early use of remdesivir treatment in patients with COVID-19 to prevent progression to pneumonia.

Researchers from the National Institutes of Health in the US noted that remdesivir has broad antiviral activity and has been shown to be effective against infections with SARS-CoV and MERS-CoV in animal models.

The drug is being tested in human clinical trials for the treatment of COVID-19, they said.

Researcher Emmie de Wit and colleagues investigated the effects of remdesivir treatment in rhesus macaques, a recently established model of SARS-CoV-2 infection.

Two sets of six macaques were inoculated with SARS-CoV-2.

One group was treated with remdesivir 12 hours later -- close to the peak of virus reproduction in the lungs -- and these macaques received treatment every 24 hours until six days after inoculation.

In contrast to the control group, the researchers found that macaques that received remdesivir did not show signs of respiratory disease, and had reduced damage to the lungs.

Viral loads in the lower respiratory tract were also reduced in the treated animals; viral levels were around 100 times lower in the lower-respiratory tract of remdesivir-treated macaques 12 hours after the first dose, they said.

The researchers said that infectious virus could no longer be detected in the treatment group three days after initial infection, but was still detectable in four out of six control animals.

Despite this virus reduction in the lower respiratory tract, no reduction in virus shedding was observed, which indicates that clinical improvement may not equate to a lack of infectiousness, they said.

Dosing of remdesivir in the rhesus macaques is equivalent to that used in humans, the researchers noted.

They cautioned that it is difficult to directly translate the timing of treatment used in corresponding disease stages in humans, because rhesus macaques normally develop only mild disease.

However, researchers said the results indicate that remdesivir treatment of COVID-19 should be initiated as early as possible to achieve the maximum treatment effect.
