Cranberries Squashed as Folk Remedy for Urinary Infections

High-protein diets may help people lose weight and build muscle, but there is a downside to it --a greater heart attack risk. Researchers now report that high-protein diets boost artery-clogging plaque.

The research in mice showed that high-protein diets spur unstable plaque -- the kind most prone to rupturing and causing blocked arteries.

More plaque buildup in the arteries, particularly if it's unstable, increases the risk of heart attack.

"There are clear weight-loss benefits to high-protein diets, which has boosted their popularity in recent years," said senior author Babak Razani, associate professor at Washington University School of Medicine in St. Louis, Missouri.

"But animal studies and some large epidemiological studies in people have linked high dietary protein to cardiovascular problems. We decided to take a look at whether there is truly a causal link between high dietary protein and poorer cardiovascular health," Razani added.

The researchers studied mice who were fed a high-fat diet to deliberately induce atherosclerosis, or plaque buildup in the arteries.

Some of the mice received a high-fat diet that was also high in protein. And others were fed a high-fat, low-protein diet for comparison.

The mice on the high-fat, high-protein diet developed worse atherosclerosis -- about 30 per cent more plaque in the arteries -- than mice on the high-fat, normal-protein diet, despite the fact that the mice eating more protein did not gain weight, unlike the mice on the high-fat, normal-protein diet.

"A couple of a scoop of protein powder in a milkshake or smoothie adds something like 40 grams of protein -- almost equivalent to the daily recommended intake," Razani said.

"To see if protein has an effect on cardiovascular health, we tripled the amount of protein that the mice receive in the high-fat, high-protein diet -- keeping the fat constant. Protein went from 15 per cent to 46 per cent of calories for these mice".

Plaque contains a mix of fat, cholesterol, calcium deposits and dead cells. Past work by Razani's team and other groups has shown that immune cells called macrophages work to clean up plaque in the arteries.

But the environment inside plaque can overwhelm these cells, and when such cells die, they make the problem worse, contributing to plaque buildup and increasing plaque complexity.

"In mice on the high-protein diet, their plaques were a macrophage graveyard," Razani informed.

To understand how high dietary protein might increase plaque complexity, Razani and his colleagues also studied the path protein takes after it has been digested -- broken down into its original building blocks, called amino acids.

"This study is not the first to show a telltale increase in plaque with high-protein diets, but it offers a deeper understanding of the impact of high protein with the detailed analysis of the plaques," said Razani.

"This work not only defines the critical processes underlying the cardiovascular risks of dietary protein but also lays the groundwork for targeting these pathways in treating heart disease," he added.

Washington, Jun 20: Pregnant and postpartum women are usually at a high risk of depression and anxiety - one in seven women struggle with symptoms in the perinatal period and the coronavirus pandemic is exacerbating those struggles according to a recent study.

The study was published in Frontiers in Global Women's Health, which found that the likelihood of maternal depression and anxiety has substantially increased during the health crisis.

"The social and physical isolation measures that are critically needed to reduce the spread of the virus are taking a toll on the physical and mental health of many of us," said Dr. Margie Davenport of the University of Alberta, Canada, who co-authored the study.

For new moms, those stresses come with side effects.

"We know that experiencing depression and anxiety during pregnancy and the postpartum period can have detrimental effects on the mental and physical health of both mother and baby that can persist for years," said Davenport.

Such effects can include premature delivery, reduced mother-infant bonding, and developmental delays in infants.

The study surveyed 900 women - 520 of whom were pregnant and 380 of whom had given birth in the past year - and asked about their depression and anxiety symptoms before and during the pandemic.

Before the pandemic began, 29 percent of those women experienced moderate to high anxiety symptoms, and 15 percent experienced depressive symptoms. During the pandemic, those numbers increased - 72 percent experienced anxiety and 41percent experienced depression.

Because lockdown measures have affected daily routines and access to gyms, researchers also asked women whether their exercise habits had changed. Of the women surveyed, 64 percent reduced their physical activity since the pandemic began, while 15 percent increased and 21 percent experienced no change.

Exercise is a known way to ease depression symptoms, so limited physical activity may result in an uptick in depressive symptoms. Indeed, the study found that women who engaged in at least 150 minutes of moderate physical activity a week had significantly lower symptoms of depression and anxiety.

The findings are somewhat limited given the fact that researchers could not survey women before the pandemic began (since they could not know a pandemic would occur). The women surveyed could only offer their pre-pandemic symptoms in hindsight.

Also, while the researchers asked women about their symptoms using validated measures, only mental health care professionals can validly diagnose an individual with depression or anxiety.

The study was specifically interested in the impact of COVID-19 on new moms, but Davenport says maternal mental health is a critical issue no matter the time.

"Even when we are not in a global pandemic, many pregnant and postpartum women frequently feel isolated whether due to being hospitalized, not having family or friends around or other reasons," she said.

"It is critical to increase awareness of the impact of social (and physical) isolation on the mental health of pregnant and postpartum women," Davenport added.

Increased awareness makes diagnosis and treatment - the ultimate goal - more likely.

The practice of washing your hands for 20 seconds is one of the best preventive measures you can take to avoid the spread of any virus including coronavirus as recommended by the WHO.

The modern day concept of handwashing was introduced by Hungaraian doctor Ignaz Semmelweis, in 19-th century Vienna. Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in the city's general hospital.

Decades later, in the modern times too the practise has not lost it's relevance. To connect with savvy consumers the message is being sent through social media? But social media can also be a dark place where misinformation is rampant; consumers can end up being misguided and compromised on sensitive issues like health and hygiene.

Dettol, recently kickstarted its #HandWashChallenge on TikTok aiming to raise awareness on four simple steps of handwashing. Strategically aimed at creating awareness among audience, a unique song has been created pairing it extremely well with the hashtag #HandWashChallenge. The hashtag filter has a branded Dettol strip across the top with the hashtag and names the steps involved in washing hands. The user can dance out the steps to the challenge and share it with their friends to further amplify the message on hygiene and safety.

Commenting on the same, Pankaj Duhan, Chief Marketing Officer, RB Health South Asia said, "We are elated with the response to the #HandWashChallenge, it has definitely become one of the most successfully led initiatives by any of our brands at RB. Understanding the consumer's mindset is of the utmost importance to us, therefore our campaign communication is built in a way that creates meaningful conversations to drive awareness amongst consumers. The participation by TikTok users across India has helped deliver the right message in a more engaging and interactive manner.

"I personally would like to encourage more and more people to join this global health & hygiene educational exercise. Together, let us all build a healthier nation, four steps at a time."

He further said, "Over the past couple of weeks we have witnessed a lot of misinformation floating around hygiene practices, especially over the internet. Realizing the gravity of the issue and being the responsible brand, we felt it was our prerogative to initiate this awareness campaign."

The campaign witnessed several quirky activities on each day leading to increased consumer interest. Joining the force were some of Bollywood's popular celebrities like Kartik Aaryan and Urvashi Rautela among several other TikTok influencers who have millions of followers on the platform. As part of Phase II, Dettol plans to take the challenge global by encouraging more users to participate while the audience worldwide.

The challenge has witnessed over 18 Billion views and generated over 123K user participation videos in one week of starting the campaign.
