New HIV Vaccine Shows Promise In Human Trials

Washington, Jul 26: An experimental HIV vaccine was well-tolerated and generated immune responses against the deadly virus in healthy human adults, scientists say.vaccine

The vaccine regimens evaluated in APPROACH - an early- stage clinical trial - are based on "mosaic" vaccines designed to induce immunological responses against a wide variety of HIV subtypes responsible for HIV infections globally, researchers said.

They found that different mosaic vaccine regimens were well-tolerated and capable of generating anti-HIV immune responses in healthy, HIV-negative adults.

Researchers found that the vaccine called Ad26.Mos.HIV was most protective in pre-clinical studies in animals elicited among the greatest immune responses in the study participants.

"A safe and effective HIV vaccine would be a powerful tool to reduce new HIV infections worldwide and help bring about a durable end to the HIV/AIDS pandemic," said Anthony S Fauci, Director at National Institute of Allergy and Infectious Diseases (NIAID) in the US. "By exploring multiple promising avenues of vaccine development research, we expand our opportunities to achieve these goals," Mr Fauci added.

Researchers randomly assigned 400 volunteers in the US, Rwanda, Uganda, South Africa and Thailand to receive one of seven experimental vaccine regimens or a placebo.

Participants received four vaccinations over 48 weeks: two doses of an initial, or "prime," vaccine, followed by two doses of a booster vaccine.

The experimental regimens all incorporated the same vaccine components in the prime vaccination, Ad26.Mos.HIV.

The vaccine used a strain of common-cold virus engineered so that it does not cause illness, as a vector to deliver three mosaic antigens created from genes from many HIV variants.

The booster vaccination included various combinations of the Ad26.Mos.HIV components or a different mosaic component, and two different doses of a protein containing an aluminium adjuvant to boost immune responses.

Researchers found that the most effective prime-boost regimen reduced the risk of infection per exposure to simian human immunodeficiency virus (SHIV) by 94 per cent and resulted in 66 per cent complete protection after six exposures.

The team identified and characterised the vaccine-induced immune responses that correlated with this protection.

"The promising, early-stage results from the APPROACH study support further evaluation of these candidate vaccines to assess their ability to protect those at risk of acquiring HIV," said Dan H Barouch from NIAID.

There is no evidence that the Bacille Calmette-Guerin (BCG) vaccine, which is primarily used against tuberculosis, protects people against infection with the novel coronavirus, the World Health Organization (WHO) said.

The WHO therefore didn't recommend BCG vaccination for the prevention of COVID-19 in the absence of evidence, according to its daily situation report on Monday, Xinhua news agency reported.

"There is experimental evidence from both animal and human studies that the BCG vaccine has non-specific effects on the immune system. These effects have not been well characterized and their clinical relevance remains unknown," WHO stated.

Two clinical trials addressing the question are underway, and WHO will evaluate the evidence when it is available, it noted.

BCG vaccination prevents severe forms of tuberculosis in children and diversion of local supplies may result in an increase of disease and deaths from the tuberculosis, it warned.

Washington D.C., Jan 3: A new study has found out that diet significantly affects the mental health and well being of an individual.

The study was published in the journal European Neuropsychopharmacology.

"We have found that there is increasing evidence of a link between a poor diet and the worsening of mood disorders, including anxiety and depression. However, many common beliefs about the health effects of certain foods are not supported by solid evidence," said the lead researcher, Professor Suzanne Dickson.

According to the researchers, the link between diet and mental health can be firmly established in certain cases like that of the ability of a ketogenic diet being helpful for children with epilepsy and the impact of vitamin B12 deficiency on poor memory, depression and fatigue.

"With individual conditions, we often found very mixed evidence. With ADHD for example, we can see an increase in the quantity of refined sugar in the diet seems to increase ADHD and hyperactivity, whereas eating more fresh fruit and vegetables seems to protect against these conditions," said Dickson

But there are comparatively few studies, and many of them don't last long enough to show long-term effects," added Dickson.

The study further concludes that some food items can be associated with treatment and the betterment of certain mental health conditions.

Food with high water content is highly prescribed by doctors to stay hydrated during the summers, a season that summons a wave of soaring temperatures, higher than 40-degrees.

A much-loved fruit in India, apples are hydrating heros' in such a situation. A heatwave can affect human health in a varied manner and to maintain ideal body temperature in this soaring summer, one must remain adequately hydrated, be protected from the sun and maintain hygiene.

Working professionals and people who must step out in summers, are prone to the heatwave impact. Pediatric experts and doctors agree on the benefits of drinking water and eating fruits, especially, apples. 'An apple a day, keeps the doctor away' is true as they are rich in a number of vitamins with great anti-inflammatory benefits and many other essential minerals. Washington Apple Commission spells how apples can prove to be a summer-friendly fruit.

People often don't realise the danger of exposing themselves to extreme heat. Older adults, young children, and people with chronic illnesses are most at greater risk for serious problems. The nutrition benefits of apples may help not only in avoiding such illnesses but may also protect against many such conditions.

As popular as apples are as a fruit, they are enriched in antioxidants, dietary fibers, vitamins and a range of other nutrients that are greatly beneficial in maintaining good health. The fruit is rich in soluble fibers which may help prevent several health conditions and may lower the risk of major diseases such as heat strokes, diabetes and cancer.

The soluble fiber also promotes weight loss and improves gut health. The prebiotic effects of apples help feed the good bacteria in the gut, thus, improving digestion.

Apples are made of 85 percent water and contain vitamins, fibres and antioxidants. A high fibre content is a particularly beneficial property of apples, as improper digestion is a major health concern in the tropical climatic region. Apples are also enriched in antioxidants that help protect the lungs from oxidative damage and help oxygen flow through the blood.
