A Harvard study reveals that just one teaspoon of olive oil may reduce the chance of dementia-related mortality.

Published

A daily allowance of 5 grammes of mayonnaise and 5 grammes of vanaspati substituted with an equivalent quantity of olive oil may reduce the risk of dementia-related mortality by 14% and 8%, respectively.

A teaspoon of olive oil per day is associated with a nearly thirty percent reduction in the incidence of dementia-related mortality, especially in women, according to recent studies.

It was shown that substituting equivalent amounts of olive oil for the five grammes of mayonnaise and margarine (also known as “vanaspati”) per day was linked to a 14% and 8% decreased risk of dementia-related mortality, respectively.

Over 92,000 individuals in the US were followed for 28 years by a multinational team of researchers, including those at Harvard University, to examine the impact of olive oil consumption on the risk of dementia-related mortality. Dementia is characterised by a diminished capacity for memory, thought, and decision-making, which affects day-to-day functioning and quality of life.

“Consuming at least 7 grammes per day of olive oil was associated with a 28 per cent lower risk of dementia-related death compared with never or rarely consuming olive oil,” the researchers noted. They also discovered that the outcomes were stable independent of the diet’s quality.

In the research that was published in The Journal of the American Medical Association (JAMA) Network Open, the authors stated, “The findings extend the current dietary recommendations of choosing olive oil and other vegetable oils for cognitive-related health beyond heart health.”

According to the experts, regular use of olive oil may improve heart health and reduce the chance of dementia-related mortality.

The specialists say that using olive oil on a daily basis can lower the risk of dementia-related death and enhance heart health.

It has been demonstrated that adhering to diets like the Mediterranean, DASH, and MIND—all of which call for consuming a teaspoon of olive oil in addition to green leafy vegetables, legumes, nuts, and fish—improves brain structure and cognitive performance.

The most olive oil consumption was associated with the lowest risk of dementia-related death, suggesting a “potentially specific role for olive oil,” according to the research team.

It was discovered that individuals with the APOE e4 gene, the most prevalent genetic risk factor for Alzheimer’s disease, had a five to nine times higher chance of passing away from dementia. Dementia with Alzheimer’s disease is the most prevalent kind.

The authors noted that even after taking this issue into consideration, the results on olive oil intake remained valid.

Growing number of whooping cough infections in the US and Europe raises concerns among medical professionals

Published

on

Cases of whooping cough, also known as pertussis, are increasing in the US and Europe. Experts claim they don’t know why. Health professionals throughout the European continent began to notice something strange in the winter of 2023. Pertussis, another name for whooping cough, was becoming more common. Furthermore, it wasn’t limited to Europe. Additionally, US health officials started to record an increase in instances of whooping cough. Furthermore, the number of cases in the UK has reached its highest level in twenty years.

The number of cases in Europe had increased by March 2024 compared to the previous ten years (the European Centre for Disease Prevention and Control (ECDC) did not issue numbers before to 2011). In Europe, reports of 32,000 instances were received between January and March of 2024. The ECDC estimates that 38,000 cases of pertussis are reported annually on average throughout Europe. Whooping cough incidences could tenfold rise in 2024 compared to a normal year if the current trend persists.

The bulk of instances in Europe occurred among newborns, a population for which whooping cough can be fatal, according to data from the ECDC’s most recent study on the matter. Ten to fourteen-year-olds accounted for the second-highest reported case group.

Paul Hunter, an English professor of medicine at the University of East Anglia, said DW that these numbers should be regarded cautiously. He indicated there might be more cases than were recorded. Babies are significantly more likely than other demographic groups to be diagnosed with whooping cough because they are at such a high risk of contracting it. It’s possible that a large number of elderly people suffer undiagnosed whooping cough as well.

However, Hunter added that there’s a chance that a similar spread is occurring. According to him, doctors may be more inclined to diagnose cases now that they are aware of whooping cough than they were in the past, which could further skew the statistics.

Use of vaccines during pregnancy

The symptoms of whooping cough initially resemble a cold. A low-grade fever, runny nose, sneezing, and sporadic coughing are possible symptoms for patients. However, after a few weeks of having pertussis, coughing fits that sound like a high-pitched “whoop” may begin. While minor cases might not have the accompanying whoop, the sickness is most severe in youngsters and newborns. Up to ten weeks may pass during this phase.

Say experts, they have no idea why there is a spike in instances. Like most infectious illness outbreaks, this one might be caused by a number of unrelated events happening all at once. It might be the outcome of the consistent drop in pertussis vaccinations given to expectant mothers throughout Europe, in addition to a general reduction in infant vaccination rates. This would provide some insight into the newborns’ situation. If their mothers did not receive a vaccination throughout their pregnancies, the newborns have no defence against whooping cough.

“​​You only start vaccinating children against whooping cough at about eight weeks,” Hunter stated. “And the majority of the most serious illnesses typically occur earlier than that.” The May ECDC report states that rates of pertussis immunisation during pregnancy vary greatly around the European continent. In 2023, 88% of expectant Spanish citizens received a pertussis vaccination. Just 1.6% of people in the Czech Republic, where instances of pertussis have sharply increased, had received the vaccination in the same year. Pregnant women’s uptake in the UK has decreased over the last ten years, going from over 70% in 2016 to roughly 60% in 2023.

The role of COVID
Furthermore, the increase may have resulted from a decline in population-wide immunity following the COVID-19 pandemic, as reported by health experts. The pandemic’s stringent measures to prevent SARS-CoV-2, such as mask use, hand washing, and limiting social interaction in public areas, resulted in historically low levels of flu and strep infections.

Cases have resumed growing since the pandemic’s termination. However, according to Hunter, that is insufficient to account for the sharp rise in whooping cough cases. This is because, before to the pandemic, whooping cough was not a serious illness in the general population. It was uncommon, but it was there. Not the flu, though. In the years after the pandemic, the number of flu cases may have doubled.

vaccination against pertussis

According to specialists, the whooping cough vaccines themselves may be the third potential aggravating reason. Midway through the 20th century, developed nations including the US, Canada, and portions of Europe saw the introduction of the first pertussis vaccination. It has unfavourable side effects despite being incredibly powerful. The ensuing dramatic decline in uptake resulted in outbreaks during the 1970s and 1980s.

Countries started rolling out second-generation pertussis vaccines in the late 1990s and early 2000s. Instead of using a full cell, this new version used an acellular shot. It was somewhat less successful than the first vaccine, providing immunity for a shorter duration, even though it did not cause the side effects.

What should I do next?
According to Andrew Preston, a professor and whooping cough expert at the University of Bath in the UK, the increase in instances raises challenging questions for medical professionals treating whooping cough, as reported by DW. He stated that while using boosters to reduce spread would be a possibility, “it’s not entirely clear how often you can boost without losing effectiveness.”

Or are we content with the current state of affairs, where everyone else only has to occasionally deal with a persistent cough as long as we can prevent newborns from being seriously sick and dying? Preston mentioned that there are pertussis vaccinations available now, some of which have the potential to confer “far superior” immunity in comparison to the two now in use.

But he said that it would be difficult to include these doses into the present immunisation regimen. In the UK and much of Europe, the pertussis vaccination is given in combination with five other vaccines in a single shot; therefore, adding a new vaccine would need redesigning the existing combination vaccine. “You’d have to reformulate all those other vaccines, and that’s just a monstrous task,” Preston added.

World Thyroid Day 2024: The date, background, importance, and essential information

Published

on

2024’s World Thyroid Day: The thyroid gland is a very important organ that is in charge of several bodily processes, including growth, development, metabolism, and reproduction. Thyroxine and triiodothyronine are the two hormones produced by the thyroid gland, a tiny gland located near the base of the neck. These hormones make sure that the body continues to operate normally. World Thyroid Day is observed annually to raise awareness of the importance of the thyroid gland and to encourage people to learn more about the diseases that may have an impact on it. Here are some things to consider as we prepare to commemorate this unique day.

Date:

May 25th is designated as World Thyroid Day each year. World Thyroid Day is on Saturday this year.

History:

The European Thyroid Association was established on May 25, 1965. The first organisation to recognise World Thyroid Day was this one. The Thyroid Federation International announced May 25 to be World Thyroid Day each year in 2007. They decided to celebrate the European Thyroid Association’s founding day on May 25. Ever since, May 25th is set aside as World Thyroid Day.

Significance:

Non-Communicable Diseases (NCDs) is this year’s World Thyroid Day theme. Among the most prevalent endocrine illnesses are thyroid issues. The purpose of the day is to raise awareness of the importance of the thyroid gland and the ways in which we can guarantee that those suffering from thyroid disorders receive accurate diagnosis and have access to appropriate care. Learning about the activities of the thyroid gland and how to take care of it is the ideal approach to commemorate this wonderful day. In addition, we can help those who suffer from thyroid disorders and make efforts to ensure that they get the right care and have healthier lives.

Are vitamin E supplements beneficial for eye, skin, and hair health? A specialist offers insights

Published

on

The use of vitamin E to enhance the health of the skin and hair came about as a result of the ongoing hunt for the next big thing in the world of strong, healthy hair. For a long time, vitamin E supplements have been heralded as a potent treatment for a wide range of aesthetic and medical conditions, from boosting skin brightness to encouraging hair growth and strengthening eye health. With so many promises made about their advantages, it can be difficult to separate fact from fiction. Let’s explore the science of vitamin E, its possible benefits, and any risks you should know about before adding these pills to your daily regimen for health and beauty.

Alpha-tocopherol, another name for vitamin E, is a fat-soluble vitamin that is well-known for its potent antioxidant properties. These properties are crucial in averting free radical damage and safeguarding the body’s cells. In addition to its anti-oxidant qualities, Vitamin E is crucial for preserving the health of the skin, particularly by preserving the natural lipids under the skin’s surface, which, when used consistently, reduces the appearance of fine lines and delays the signs of ageing “said Dr. Madhu Chopra, MBBS, DORL, a Mumbai-based cosmetologist and managing director of Studio Aesthetique.

Vitamin E’s advantages for healthy skin
Dr. Madhu went on to say, “Vitamin E’s antioxidant properties help prevent oxidative stress, which is a major contributor to premature ageing, and they also make your skin look younger and more radiant. Moreover, vitamin E actively contributes to the creation of collagen, strengthening the protein that gives skin its structure, elasticity, and firmness and enhancing its anti-aging properties.”

Vitamin E’s benefits for healthy hair
Speaking on hair health, Dr. Madhu stated that the antioxidant qualities of vitamin E have a favourable effect on hair care, encouraging shiny, damage-free locks while halting hair loss and facilitating the quick repair of broken strands. By lowering oxidative stress and shielding hair follicles from damage caused by free radicals, vitamin E encourages the growth of hair and fosters strong hair development.”

Notably, the antioxidant properties of vitamin E strengthen hair strands from root to tip by promoting blood circulation throughout the body and scalp. Furthermore, vitamin E supports the development of strong, healthy hair by restoring dry, damaged hair follicles. However, direct administration of vitamin E is advised with caution as it may cause discomfort. Before applying, dilute vitamin E with a moisturiser or coconut oil to maximise its effects and minimise the chance of discomfort. For the best results, usage consistency is crucial,” Dr. Madhu says.
