Vitamin B3 may help treat acute kidney injury

New York, Aug 21: Oral intake of vitamin B3 could potentially help prevent acute kidney injury that affects 30-40 percent of all hospitalised adults in the low-income countries, suggests a study, led by a researcher of Indian-origin.

Acute kidney injury, an often fatal condition without a specific treatment, causes a build-up of waste products in the blood and an imbalance of fluids throughout the body.

The findings showed that levels of nicotinamide adenine dinucleotide (NAD+) — the end result of vitamin B3 after it is ingested — declines in cases of acute kidney injury.

“We were able to detect a drop in NAD+ in the urine of high-risk patients who were either in an intensive care unit or undergoing a major surgery and found that oral vitamin B3 could safely elevate NAD+ in high-risk patients,” said principal investigator Samir M. Parikh, nephrologist and associate professor at Harvard University.

“These findings are very early, but the results suggest that we could one day have a non-invasive test for NAD+ status and perhaps even treat acute kidney injury by boosting NAD+ levels,” he added.

In the study, published in the journal Nature Medicine, the team examined the metabolic changes associated with acute kidney injury in a mouse model. A urine screen revealed high levels of quinolinate.

They then created a mouse model with reduced QRPT — an enzyme responsible for converting quinolinate to NAD+ — but no kidney injury.

The genetically altered rodents mimicked the pattern of acute kidney injury; decreased NAD+, increased urinary quinolinate and increased susceptibility to kidney injury. The experiments were the first to establish QRPT as a mediator of renal stress resistance.

In subsequent human studies, the team found high urinary quinolinate in patients undergoing major surgery at risk for acute kidney injury and confirmed this metabolite pattern in a separate study of 329 intensive care unit patients also at risk for acute kidney injury.

The team then gave large doses of oral vitamin B3 to 41 cardiac surgery patients enrolled in a Phase 1 pilot study and found that augmenting vitamin B3 levels may be safe and potentially beneficial to patients.

Natural ways to boost immunity in children

Kids eating, children snacks

New Delhi, Jan 21: It is natural for parents to protect their children from any harm, including the endless array of germs they are exposed to every day.

As children grow up, they are continuously exposed to various germs, especially in places such as daycare centres and preschool. Children with low immunity are highly susceptible to various types of infections. The high incidence of infections has led to an increased and inappropriate use of antibiotics, which has further resulted in antimicrobial resistance.

Antimicrobial resistance, a widespread problem, takes places when microbes build resistance against the medications intended to kill them due to overuse. It is one of the world’s most pressing public health problems. The best way to tackle this is to build a strong immunity, which naturally protects your child from infections. Dr. Rajesh Kumawat, Head – Medical Services & Clinical Development, The Himalaya Drug Company, shares a few tips that can help boost your child’s immunity.

Healthy Diet

A healthy diet that comprises all fundamental components like proteins, minerals, vitamins, micronutrients and unsaturated fats in optimum quantity, helps build the immunity required to fight against various infections or diseases in children. Citrus fruits, carrots, green leafy vegetables, beans, strawberry, yogurt, garlic, and ginger help build immunity with their immunity-boosting properties.

Adequate Sleep

Sleep deprivation suppresses the functionality of the immune system, which makes children susceptible to infections. Adequate sleep is an absolute necessity to rejuvenate the body. Newborns need up to 18 hours of sleep a day, toddlers require 12 to 13 hours, and preschoolers need about 10 hours of sleep.

Hygiene

Maintaining hand hygiene before and after each meal, after playtime, handling pets, blowing the nose, using the restroom and arriving home from daycare helps prevent infections in children.

Herbal Solutions

Despite taking proper care, children’s immunity may be affected. Consumption of herbal dietary supplements like Guduchi (Tinospora cordifolia), Amalaki (Emblica officinalis), Yashtimadhu (Glycyrrhiza glabra), and Guggulu (Balsamodendron mukul) can help children stay healthier as they help build immunity.

“Naturally obtained supplements strengthen the immune system. Herbs like Guduchi, Yashti Madhu, and Guggulu are natural sources of antioxidants. The antiviral property of Yashtimadhu also helps manage asthma, bronchitis, and chronic cough. The anti-inflammatory property of Guggulu helps reduce inflammation,” Dr. Kumawat added.

A combination of herbs may be a safe and effective adjuvant to antimicrobials in the management of recurrent infections. When co-prescribed with antibiotics, herbs may
have a role in faster recovery, reduces the duration and cost of therapy, besides preventing reinfections.

Anti-inflammatory drugs may put you at heart attack risk

heart failure heart attack

If you have been hit by the winter cold and are thinking about taking medicines that relieve your aches, pains and congestion, be careful. Those may also put your heart at risk, the American Heart Association has warned.

A study has showed that both decongestants and non-steroidal anti-inflammatories (NSAIDs), found in many cold medicines, were listed as medications that could increase blood pressure.

People who used NSAIDs while sick were more than three times as likely to have a heart attack within a week compared with the same time period about a year earlier when participants were neither sick nor taking an NSAID.

“People with uncontrolled high blood pressure or heart disease should avoid taking oral decongestants. And for the general population or someone with low cardiovascular risk, they should use them with the guidance of a health care provider,” said Sondra DePalma, from the University of Pittsburgh in the US.

Decongestants like pseudoephedrine or phenylephrine constrict blood vessels. They allow less fluid into your sinuses, “which dries you up”, said Erin Michos, associate director of preventive cardiology at the Johns Hopkins Univerity’s Ciccarone Center in Baltimore.

The biggest concerns are for people who have had a heart attack or stroke, or have heart failure or uncontrolled high blood pressure, Michos said, in the paper published in the Journal of Infectious Diseases.

Importantly, healthy people might also be at risk.

For the study, researchers looked at nearly 10,000 people with respiratory infections who were hospitalised for heart attacks.

Participants were 72 years old on average at the time of their heart attacks and many had cardiovascular risk factors, such as diabetes and high blood pressure.

People who are sick should use both classes of medications — decongestants and NSAIDs — judiciously and understand the potential side effects.

In addition, decongestants should not be taken longer than seven days before consulting with a healthcare provider, DePalma said.

One should also rest and drink plenty of fluids if symptoms are mild or moderate, DePalma noted.

What is to be blamed for childhood cancer?

A team of researchers has thrown light on the community beliefs about what causes cancer in children, an area which remains understudied, finds a latest research.

“Few childhood cancers are attributed to genetics or environmental factors, so when children are diagnosed with cancer, families often wonder ‘why me/why us’?” said lead author Janine Vetsch, postdoctoral research candidate from UNSW Sydney in Australia.

For the study, the team examined the beliefs of more than 600 participants — parents and childhood cancer survivors — about the causes of childhood cancer, and compared them with beliefs of 510 members of the general population.

Findings, published in Acta Oncologica, revealed that more than seven out of 10 childhood cancer survivors and survivors’ parents believed that chance or bad luck caused the cancer.

This led to most parents and survivors seem to understand that there is nothing they could have done to prevent the cancer, according to Vetsch.

However, around one in five families did believe that environmental factors and genetics played a role, despite only limited available scientific evidence, results further showed.

“It looks like healthcare professionals are successfully helping most families arrive at that view,” said Vetsch.

Such views could lead to stigma. Hence, it is important to increase community knowledge of childhood cancer causes in general.

There is a need to encourage doctors to talk about the causes with affected families to address unhelpful misconceptions,” Vetsch suggested.
