How much fat and carbs do you need to consume?

July 25, 2023 blogadmin Comments 0 Comment

New publications from the World Health Organisation give the most recent scientific theories on how important lipids and carbs are to a balanced diet.

The WHO continues to advise adults to consume no more than 30% of their daily calories from fat. The new recommendations emphasize the source of carbs rather than their quantity.

For parents looking to start their kids off on a good connection with food and nutrition for the rest of their lives, the new recommendations offer new knowledge.

In general, the WHO is putting greater emphasis on quality and paying less attention to the quantity of fat and carbohydrates.

Not all of what the WHO has to say is brand-new. For instance, the group still advises adults to keep their daily fat intake to 30% or less of their total calorie intake. Calories from foods like carbs, proteins, fats, and alcohol are used to calculate a person’s daily energy consumption.

However, the prevalence of obesity has nearly tripled globally since 1975, and in 2020, 39 million children under the age of 5 will be overweight or obese, affecting approximately 340 million children and adolescents between the ages of 5 and 19. The WHO records show a new focus on the optimal diet for life.

For instance, according to WHO recommendations, children under the age of two should consume primarily unsaturated fats. WHO highly advises that people take no more than 10% of their total calories from saturated fats, with trans fatty acids making up no more than 1% of those calories.

Which fats are bad for you?

Michelle Routhenstein, a nutritionist who was uninvolved in the WHO publications, said that “in the past, it was just generally ‘limit fat to 30% of energy intake.'”

“And now, we’re really looking at saturated fat being a culprit in cardiovascular disease development because it’s directly correlated with an increase in LDL and an increase in insulin resistance, which are cardiometabolic risk factors,” said she.

The WHO warns against consuming saturated fatty acids, which are found in fatty meat and dairy products. Saturated fats are also present in coconut oil, palm oil, lard, butter, ghee, and palm oil.

Animals including cows, sheep, and goats as well as sources generated industrially are the main sources of trans-fatty acids. Deer, moose, camels, giraffes, and buffalo are further examples of ruminant mammals.

In the new papers, suggestions are provided for substituting polyunsaturated fatty acids and monounsaturated fatty acids from plant sources for harmful saturated fats and trans-fatty acids.

Carbs, fruits, and vegetables

The latest WHO recommendations show a similar shift in thinking regarding carbs.

“We are more specific about the sources of the [nutrients]. More precisely, fibers with more complex carbohydrates are of interest to us. We’re especially focusing on dietary fiber from whole grains, fruits, and vegetables since we know it has a cardiovascular protective effect,” said Routhenstein.

The use of natural fiber-rich foods such whole grains, legumes, and vegetables is currently encouraged by the WHO.

Updated recommendations for kids

While the WHO has traditionally advised adults to consume 400 grams of fruits and vegetables each day, the publications now include recommendations for kids as well.

Children aged 2 to 5 should consume 250 grammes or more of fruits and vegetables each day.
Aged 6 to 9 children should consume 350 grammes or more of fruits and vegetables each day.
Children aged 10 and older should consume 400 grammes or more of fruits and vegetables each day.

In a similar vein, the WHO now addresses children’s fibre requirements. Adults were formerly advised to ingest 25 grammes per day. Now:

At least 15 grammes of fibre per day should be consumed by children aged 2 to 5.
Children aged 6 to 9 should get at least 21 grammes of fibre per day.
At least 25 grammes of fibre per day should be consumed by children 10 and older.

Various foods, including broccoli, bananas, apples, and banana bread, contain fibre.

Healthy living starts in childhood.

The childhood obesity epidemic, which is also the reason behind [the WHO’s new emphasis], according to paediatrician Dr. Daniel Ganjian, who is also not connected to the WHO.

Dr. Ganjian added that “more and more research shows that the earlier you start teaching children about healthy nutrition and eating, the more likely it is that they will remain healthy throughout their lives.”

He especially mentioned preventing the onset of diabetes, high blood pressure, high cholesterol, and even some types of cancer.

According to Routhenstein, a dietitian who specializes in cardiovascular health, “There’s this new focus that we realize to prevent cardiovascular disease, we need to be focusing on the earlier generation because that’s where it starts.”

The focus should be on prevention rather than treatment, according to Routhenstein.

Attitudes towards food that are healthy

The primary food producers in the household are the parents. Therefore, once the parents and the child are aware of it and [the child] begins consuming it, the body forms a habit and starts to crave healthy meals rather than salty, crunchy foods, according to Dr. Ganjian.

He also emphasized the significance of teaching kids about healthy eating in the right way and claimed that instructing kids to “start watching what you eat” and use the words “overweight” or “obese” was not the ideal strategy.

It is now known that, in the long run, such strategy leads to greater anxiety—and eating disorders—than a positive eating philosophy.

“We need to change the topic of conversation from weight or body image to good nutrition. You always promote eating well,” said Dr. Ganjian.

The Summary

Try keeping track of how many carbs you consume on a daily basis and whether they are healthy or unhealthy before beginning the low-carb diet. There are helpful, unpaid apps available.

Fibre grammes don’t actually count as carbohydrates, so you can take them out of the total. As an alternative, use the formula: net carbohydrates = total carbs fibre.

Check out these potential causes if you’re not losing weight or your weight loss is sluggish when on a low-carb diet.

How non-alcoholic wine is a Magnificent anti-aging tool?

July 25, 2023 blogadmin Comments 0 Comment

Red wine has been used for its therapeutic properties for ages. Red, white, or rosé wines made from muscadine grapes are known to contain a significant amount of an antioxidant known as polyphenols.

A tiny amount of de-alcoholized wine prepared from muscadine grapes per day, according to University of Florida researchers, can help rejuvenate ageing skin.

Researchers have been debating the potential health advantages of wine, particularly red wine, for a long time. Since wine has been used medicinally for so long, some people think it may have been the earliest known “medicine.”

According to earlier research, drinking red wine may help to prevent heart disease, chronic inflammation, and cognitive deterioration. Additionally, additional studies indicate that consuming red wine may lengthen life and boost the number of beneficial bacteria in the gut microbiome.

Recent research from the University of Florida demonstrated how dealcoholized wine derived from muscadine grapes can help to improve ageing skin at NUTRITION 2023, the American Society for Nutrition’s premier annual meeting.

Skin that is more elastic and loses less water

Dr. Lindsey Christman, graduate research assistant in the University of Florida’s Department of Food Science and Human Nutrition, and her group gathered 17 women between the ages of 40 and 67 for this study. They were given the option of drinking either a wine that had been decaffeinated or a placebo that had no polyphenols.

Over the course of six weeks, study participants drank around two glasses of the given drink each day. After a three-week hiatus, individuals resumed drinking the beverage they had been abstaining from throughout the first six weeks of the study.

Each participant’s skin conditions and indicators of oxidative stress and inflammation were assessed at the start of the trial and at the conclusion of each six-week period.

Analysis revealed that participants’ skin elasticity had been greatly enhanced by consuming the de-alcoholized muscadine wine.

Dr. Christman, a co-author of this study, stated, “We were hoping that it would improve elasticity.” In dealcoholized muscadine wine, polyphenols such ellagic acid, anthocyanins, quercetin, and myricetin may lessen UVB-induced protease activation. These proteases are in charge of the elasticity loss and sagging that come along with ageing.”

Additionally, the wine was linked to a reduction in water loss from the skin’s surface, suggesting that the skin’s protective barrier was more effective.

The amount of participants’ skin wrinkles did not significantly alter throughout the trial, according to the researchers.

Furthermore, there was no discernible change in these variables between the dealcoholized wine and the placebo drink, despite the fact that there were some improvements in skin smoothness and reduced indications of inflammation and oxidative stress compared to baseline.

What makes muscadine grapes unique?

The grape species known as the muscadine grape (Muscadinia rotundifolia) is indigenous to the Southeast of the United States. They grow well in warm, humid areas, unlike other grape varietals.

Typically, these grapes are a deep purple or black colour. Red, rosé, or white wines can be made from the juice.

Polyphenols, a type of antioxidant generally found in plants, are known to be present in significant amounts in muscadine grapes.

Comparing the muscadine grape to other red wine types, researchers discovered that it has a distinctive polyphenolic profile. As a result, the biological activity may differ from that of other red wines, according to Dr. Christman.

Pre-clinical research employing cells from triple-negative breast cancer and prostate cancer has already investigated the impact of muscadine grapes on specific cancers.

Additionally, dealcoholized muscadine wine may be able to lessen the symptoms of inflammatory bowel disease, according to a mouse study that was published in June 2021.

Why is grape juice preferred over decaffeinated wine?

Wouldn’t muscadine grapes provide the same advantages given that they can also be used to manufacture alcoholic wine and grape juice? Not always, according to Dr. Christman.

These findings cannot be applied to wine that contains alcohol since alcohol introduces a new variable and could change the findings, she said. The procedure of decoholization may also have changed the wine’s overall chemical composition. Because of this, the findings also cannot be applied to juice.

However, Dr. Christman noted that the research “does suggest that muscadine wine polyphenols have the potential to improve skin conditions, so there may be a chance of the same results.”

“However, a future study would need to be done with these products in order to confirm,” she continued.

An excellent source of antioxidants is muscadine grapes.

Dr. Alexis Livingston Young, a dermatologist of the Hackensack University Medical Centre, was also consulted by experts regarding this study.

The findings of the study, according to Dr. Young, were not unexpected given what we already know about the health advantages of consuming muscadine grapes.

She explained, “Muscadine wine is a good source of resveratrol, which is a potent antioxidant.”

“Muscadine grapes have some of the greatest antioxidant levels of any fruit, and they contain more of this chemical than other varieties of grape. Antioxidants are known to help the body produce fewer free radicals,” she continued.

“Free radicals are associated with several chronic conditions, including diabetes, heart disease, and aging-related cell and tissue damage. Therefore, the research demonstrated that the antioxidants in these grapes may definitely encourage improved skin and prevent the development of wrinkles,” according to Dr. Alexis Livingston Young.

Dr. Young stressed again how beneficial it would be to conduct more research on this issue.

“Since this study was somewhat small, I would like to see additional research conducted with a larger sample size over a longer time frame. But I do believe that this is a fantastic place to start,” she added.

Ways to delay skin ageing

Your body’s largest organ is actually the skin that covers it.

A person’s skin has three layers:

The top layer is called the epidermis.
The middle layer, or dermis, is where the body’s blood vessels, nerves, and other crucial components are located.
The innermost skin layer, the hypodermis, includes fat cells.

The epidermal layer thins with age, making the skin appear more translucent. In parts of the epidermis that may have been harmed by excessive sun exposure earlier in life, dark age spots may start to appear.

Additionally, the collagen-containing connective tissue that holds the various skin layers together starts to deteriorate. The skin may start to sag and wrinkle as a result of this.

There are steps people may take to assist slow down the skin ageing process, even though it is impossible to stop the ageing process. The American Academy of Dermatology Association offers the following advice:

Put on sunscreen
daily use of a face moisturiser
Skip the tanning bed.
employ calming skin care products
examine retinol cream
maintain a healthy lifestyle.

Is Alzheimer’s Disease Detectable by Finger Prick Test?

July 25, 2023 blogadmin Comments 0 Comment

The ability to diagnose and monitor Alzheimer’s disease remotely may be possible with finger prick tests, according to research.

In contrast to primary care physicians, who only have about 55% accuracy, a different study indicated that blood tests have over 85% accuracy in diagnosing Alzheimer’s disease.

The accuracy and accessibility of diagnosing and managing Alzheimer’s disease may potentially be improved by blood tests.

The number of Americans who have Alzheimer’s disease is currently at 6 million. This number is expected to rise to about 13 million by the year 2050.

Even though there is presently no cure for Alzheimer’s, research have shown that early detection and treatment are essential for postponing the disease’s onset.

Magnetic resonance imaging (MRI), cognitive testing, and physical examinations are currently used as diagnostic techniques. However, access to them is limited because it calls for going to a clinic with knowledgeable staff and involved sample delivery and storage processes.

These tests’ degree of accuracy vary as well. According to a research, almost 25% of people who received a lifetime clinical diagnosis of likely Alzheimer’s had no signs of the disease when they were autopsied.

Furthermore, according to research, up to 50% of dementia sufferers never receive a formal diagnosis while they are still living.

The capacity to detect Alzheimer’s disease earlier and administer treatments that may slow disease development could be aided by increasing the reliability and accessibility of Alzheimer’s testing.

A method for analysing finger prick tests for Alzheimer’s that may be performed at home without a doctor’s supervision was recently developed by researchers.

In contrast to conventional physical examinations, which only accurately diagnose patients with Alzheimer’s disease about 55% of the time, blood tests can detect the disease with a rate of over 85% accuracy.

Alzheimer’s blood tests you can do at home

77 patients from a Barcelona, Spain, memory clinic were involved in the study. All participants gave blood samples from their veins and finger pricks, as well as taking cognitive tests.

For overnight delivery to the University of Gothenburg in Sweden, blood samples were either spotted and dried on “dry blood spot” (DBS) cards or preserved using an anticoagulant called ethylenediamine tetraacetic acid (EDTA).

DBS cards are simpler to carry than EDTA blood samples because they just need to be protected from humidity and moisture. Additionally, centrifugation—the mechanical separation of fluids based on their density—must be performed on EDTA samples before they can be studied, but not on DBS samples.

The blood samples were then examined in Sweden for indicators of Alzheimer’s disease, such as phosphorylated tau, glial fibrillary acidic protein (GFAP), and neurofilament light (NfL).

They noticed that all of the blood samples contained indicators for Alzheimer’s disease. As a result, they claimed, Alzheimer’s biomarkers may be measured with finger prick collection, and DBS might facilitate routine monitoring of patients with possible neurological problems.

How precise are Alzheimer’s blood tests?

Dr. Sebastian Palqvist, Ph.D., associate professor at Lund University in Sweden, and colleagues compared the effectiveness of blood-based biomarkers for detecting Alzheimer’s disease with examinations from primary care physicians in a second study that will also be presented at the Alzheimer’s Association International Conference.

They had 307 patients, ranging in age from middle-aged to old, with a mean age of 76. Cognitive evaluations and a CT or MRI scan were part of primary care examinations. Additionally, participants donated a sample of venous blood, which was examined to evaluate the levels of beta-amyloid and phosphorylated tau.

Blood tests accurately detected Alzheimer’s more than 85% of the time, whereas primary care doctors only correctly identified alterations associated with Alzheimer’s 55% of the time.

According to a news release from Dr. Palmqvist, primary care physicians may find it challenging to diagnose Alzheimer’s due to a lack of precise diagnostic equipment.

This too frequently results in misdiagnosis and ineffective therapy. Alzheimer’s blood tests have enormous promise for increasing diagnostic precision and providing patients with the best care possible. In the near future, as new medications that slow the disease in its early stages become more widely accessible, these tests might become even more crucial.

A faster, less expensive method of diagnosis

“We see these new tools improving our ability to recognise the earliest changes of Alzheimer’s and ultimately speeding our ability to prevent or delay the onset of memory decline,” said Dr. Jeffrey Burns, neurologist and co-director of the University of Kansas Medical Center’s Alzheimer’s Disease Research Centre, who was not involved in the study.

“The general public will soon have access to these instruments. We anticipate the FDA approving blood tests for Alzheimer’s within the next one to two years”. Dr. Jeffrey Burns stated, “We are entering a new and exciting era of Alzheimer’s disease with novel diagnostic and treatment options that will significantly alter how we practise.“

Psychiatrist and director of the Pacific Brain Health Centre at the Pacific Neuroscience Institute in Santa Monica, California, Dr. David Merrill, Ph.D., who was not involved in the study, said that there is currently a shortage of specialists who can perform the extensive testing required to diagnose Alzheimer’s.

“Lumbar puncture tests and radioactive brain scans are riskier, more expensive, and require specialised medical care. Even today’s blood tests require specialist processing and handling to prevent results from being tainted,” he said.

“If this method is validated, it could increase the number of patients screened for Alzheimer’s and may help catch the disease early, when interventions can have a greater impact,” said Dr. Jennifer Bramen, Ph.D., a senior research scientist at the Pacific Neuroscience Institute in Santa Monica, California, who was also not involved in the study.

“A simple finger prick of blood put onto a card that can be shipped directly from a patient’s home at room temperature simplifies the process of getting tested for Alzheimer’s,” explained Dr. David Merrill.

Why only a blood test may not be sufficient?

Dr. Bramen pointed out that the findings were limited by the fact that it was a tiny pilot study and that the research procedures and conclusions had not yet undergone peer review.

Detecting amyloid is not the same as diagnosing Alzheimer’s, Dr. Burns continued. It will be crucial to discover the optimal ways to use these technologies in clinical practise, he added.

A neuropsychologist at Baptist Health Marcus Neuroscience Institute named Dr. Raphael Wald, Psy.D., who was not engaged in the study, was also consulted by experts. Although the test may be helpful in corroboration of an Alzheimer’s diagnosis, he pointed out that it does not reveal the severity of an individual’s impairment.

“Some persons can manage their daily lives quite well despite having Alzheimer’s disease as determined by other testing. Others are severely damaged and show no indications of Alzheimer’s,” he said.

Dr. Merrill added that while blood testing might be more accurate than just gathering medical histories, physicians must also think about the care that would follow.

Will confirmatory testing be easily accessible? Who will pay for the test’s repeatability and how often can or should it be performed? Will blood spot testing be recognised as a starting point for therapies, or will additional testing be necessary? How will newly diagnosed patients be supported? Alzheimer’s disease diagnosis can be a heartbreaking event. Before making this test available to the entire public, there are still many details to be resolved,” he said.

Alzheimer’s disease and protein imbalance in middle age.

July 24, 2023 blogadmin Comments 0 Comment

Even though Alzheimer’s disease is the most prevalent form of dementia, it is not a natural part of ageing and affects an increasing number of people.

The hunt for early disease markers is ongoing because early diagnosis and treatments help both dementia patients and their carers.

Now, 32 proteins have been related to the later development of Alzheimer’s disease in middle-aged persons after a lengthy investigation. The researchers advise more investigation into these proteins as potential indicators of Alzheimer’s disease.

The most prevalent type of dementia, Alzheimer’s disease, affects more than 6 million people in the United States. According to the World Health Organisation, Alzheimer’s disease is to blame for 70 percent of the 55 million cases of dementia globally.

Alzheimer’s symptoms can be treated, but there is currently no known cure for the condition. Trials of new drugs, however, are encouraging.

Donanemab, lecanemab, and aducanumab, novel monoclonal antibody medications that remove amyloid proteins from the brain, appear in clinical trials to delay the onset of disease symptoms.

Early diagnosis is essential to successful therapy because studies have shown that these drugs work best when administered during the early stages of the disease. Donanemab trial data recently made public indicate that the medication dramatically slows the clinical course of Alzheimer’s when taken soon after symptoms first occur.

Proteins that are connected to the later development of Alzheimer’s have been found in a recent study of adults between the ages of 45 and 65.

What is the disease Alzheimer’s?

A form of dementia that progresses is Alzheimer’s disease. A condition that adversely impacts memory, thinking, and behavior is referred to as dementia. The modifications make daily life more difficult. There are numerous possible causes of dementia, including diseases and brain traumas. Sometimes there is no known cause.

The Alzheimer’s Association estimates that 60 to 80 percent of dementia cases are caused by Alzheimer’s disease. The condition is typically diagnosed in patients over the age of 65. Alzheimer’s disease is typically described as having an “early onset” or “younger onset” if it is discovered earlier.

Alzheimer’s has no known cure, but some medications can halt the disease’s growth.

A 32 protein biomarker imbalance

The goal of this study was to find proteins that are improperly expressed in middle-aged persons (defined as those between the ages of 45 and 65) who later experience dementia.

Researchers collected blood samples from 10,981 individuals with a mean age of 60 at the beginning of the trial, between 1993 and 1995. Then, using the blood samples, they examined more than 4,800 plasma proteins.

1,874 patients (17%) had dementia diagnoses over the course of the 25-year follow-up period.

32 plasma proteins were discovered by the researchers to be linked to dementia risk. GDF15, a protein involved in inflammation, oxidative stress, and metabolic and immunoregulatory regulation, showed the highest correlation.

They next looked into whether proteins were linked to dementia risk in the short-term (within 15 years of protein measurement) and long-term (beyond 15 years following protein measurement).

Seven midlife proteins, including GDF15 and others related in immunology, growth factor binding, protein breakdown, and nerve and synaptic function, were linked to a higher chance of developing near-term dementia.

Along with six other proteins that were not prominent at the 15-year mark, GDF15 was also linked to a risk of long-term dementia, indicating that the molecular pathways underlying the risk of dementia evolve with time.

Early warning signs of Alzheimer’s disease

The proteins were also discovered in some of the brain tissue. However, GDF15, which was linked to both short- and long-term risks of dementia, was not found by the researchers in the brain tissue.

They contend that rather than being an Alzheimer’s disease-specific protein, it is connected to the neuroinflammation that is linked to aging-related disease.

However, they think they have “identified several pathway-specific plasma proteins that may be relevant in the earliest phase of Alzheimer’s and related dementias.” The researchers did not discover any direct causal links between proteins and Alzheimer’s.

Do new Alzheimer’s tests result from this?

“Although the dementia-associated proteins alone did not provide a highly accurate prediction of 25-year dementia risk, these proteins, in combination, did add modest predictive value to a group of demographic and clinical variables which are themselves strong predictors of dementia risk,” the study’s authors stated.

The proteins that have been discovered, according to the researchers, ought to serve as the starting point for additional study because they might be dementia risk factors.

Additionally, they assert that their findings might shed light on pertinent biological pathways and make it easier to uncover illness early signs and molecular triggers.

Therefore, with more study, these proteins might be helpful in determining a person’s risk of dementia. We will have to wait and see if they contribute to the development of new dementia diagnostic tests.

Superagers: Why resistant to age-related memory decline?

July 24, 2023 blogadmin Comments 0 Comment

An observational study investigated whether age-related memory decline may not affect superagers, or those 80 years and older who possess the cognitive abilities of people who are decades younger.

In comparison to older persons with cognitive deterioration, the octogenarians with strong memory retention moved more quickly and experienced lower levels of worry and depression. Additionally, MRI scans revealed that certain memory-related brain regions had increased grey matter in super-agers.

Superagers are people over the age of 80 whose recollections of their past are just as clear as those of others who are 20 or 30 years younger. Scientific research is becoming increasingly interested in the mechanisms of superaging.

According to a recent study, older persons with cognitive decline had higher rates of anxiety and despair compared to octogenarians with strong memory retention. They also do better on movement tests.

The researchers speculate that such superagers may also have more grey matter in their brains.

In a press release, the study’s first author Marta Garo-Pascual, a Ph.D. candidate at the Technical University of Madrid in Spain who studies healthy memory ageing, stated:

“We are now getting closer to answering one of the most important outstanding concerns about superchargers: whether they are actually resistant to age-related memory decline or whether they have coping mechanisms that allow them to outperform their contemporaries in overcoming this decline. Although the specific causes of super agers resistance to these processes are still unknown, our data suggest they do. We may be able to learn vital information about the mechanisms underlying the maintenance of memory function well into old life by investigating the connections between superaging and movement speed in more detail.”

Superagers: Exercise promotes the health of the brain

For the study, 55 typical older persons and 64 superagers who were identified by a memory test used in a prior study on Alzheimer’s disease were compared. The average age of research participants was 79.5 years or higher.

The Timed Up and Go Test, which assesses mobility, and a finger-tapping test, which gauges fine motor function, revealed that the superagers outperformed the general population.

Even when super agers reported no appreciable change in exercise levels from the older people in the control group, the findings persisted.

The study’s principal author, Dr. Bryan Strange, a neurologist at the Technical University of Denmark, noted that although superagers report similar activity levels to average older adults, it’s possible that they engage in more physically taxing hobbies like gardening or stair climbing.

“There are many direct and indirect benefits of being physically active that may contribute to improved cognitive abilities in old age, from lower blood pressure and obesity levels to increased blood flow to the brain,” stated Dr. Bryan Strange.

It’s also plausible that the reason superagers move more quickly is because their brains are in greater health to begin with, according to Strange.

The amount of grey matter in superagers brains is higher.

The results also supported earlier studies that found super-agers have more grey matter in the brain regions linked to memory.

Researchers Dr. Alexandra Touroutoglous, Dr. Bonnie Wong, and Dr. Joseph M Andreano of Harvard Medical School wrote in an editorial statement that accompanied the article that this discovery predominantly focused on the medial temporal lobe of the brain, “which is consistent with previous research.”

The comments pointed out that previous studies on the anterior mid-cingulate cortex, another crucial area of the brain, reported more cortical thickness and stronger functional connectivity among super-agers, who in turn had greater memory performance.

The attention, memory, executive function, and motivation are just a few of the processes that the anterior mid-cingulate cortex is involved in.

The researchers concluded that “[the] greater performance of super agers relative to typical older adults may not only reflect differences in motivation, executive function, and persistence in the face of difficulty, which suggests that super-agers have a higher level of tenacity than typical older adults.”

Compared to other older individuals, superagers age differently.

According to the University of Madrid study, there were no discernible differences between superagers and other adults of a similar age in terms of biomarkers or genetic risk factors for neurological illness. This suggests that another protective mechanism may be at play.

Similar levels of dementia blood biomarkers were found in both the superager and standard older adult groups, the researchers said, “suggesting that group differences reflect inherent superager resistance to typical age-related memory loss.”

The study’s large sample size, according to Dr. S. Jay Olshansky, a professor in the Division of Epidemiology and Biostatistics at the University of Illinois at Chicago School of Public Health, makes the results an essential addition to the field of “geroscience,” the research of mechanisms that cause aging.

Dr. Olshansky stated, “We do a lot of things to shorten our lives by adopting unhealthy lifestyles,” and many superchargers and centenarians people who live past 100 live longer and have better cognitive health because they age differently from the general population.

Do super-agers have a hereditary propensity for aging?

The appearance of some children of superchargers, Dr. Olshansky recalled, supported the idea that some people’s “biological time clock ticks at a slower rate” due to genetic factors. This is said to also explain why the superchargers in the Spanish study also performed better on movement tests.

Even though they have completed 80 orbits around the sun, he claimed that they are not biologically 80 years old.

“Asking superagers for their key to longevity is therefore ludicrous because they have no idea. They recently emerged as the birth genetic lottery winner.

The latest study, according to Dr. Olshansky, attempts to better understand why some people age differently than others and determine whether the process may be changed.

He said, “Start with not shortening your life,” in the meanwhile. “We will still age and pass away, even if you control all the risk factors,” he stated. We are at the mercy of our genes, but we have some power over those genes.

Important benefits between heart and regular exercises.

July 24, 2023 blogadmin Comments 0 Comment

Although getting regular physical activity throughout the week may be challenging, it is good for cardiovascular health.

Regular moderate to vigorous physical activity during the week had similar effects on cardiovascular health as moderate to vigorous physical activity concentrated over one to two days, generally the weekend, according to a recent study.

The results demonstrated that the risk of heart attacks, atrial fibrillation (AFib), heart failure, and stroke was reduced in both “weekend warriors” and regular exercisers.`

Exercise has important health benefits, such as lowering the risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome. Some people may find it challenging to engage in regular physical activity during the week, which may cause them to engage in more intense physical activity on the weekends.

A recent study compared patterns of physical activity behaviour between individuals who spread their physical activity out over the course of the week with those who concentrated their moderate to strenuous physical activity over one or two days.

According to research, both forms of exercise were linked to a similar reduction in the risk of heart attack, atrial fibrillation, heart failure, and stroke.

Weekend workouts versus weekday workouts

The present study’s researchers emphasized that the recommended amount of exercise is 150 minutes per week of moderate to intense activity.

They sought to determine whether the linked health advantages changed between two important groups:

Weekend warriors are those who engage in a sustained period of moderate to vigorous physical activity over one to two days. Individuals who evenly distribute their moderate to vigorous physical activity throughout the week

A group with activity levels of fewer than 150 minutes per week was also included by the researchers in order to establish an exact comparison. This group was deemed inactive because they fell short of the required amount of activity per week.

The UK Biobank cohort study’s nearly 90,000 participants were included in the study. Participants tracked their physical activity levels by wearing accelerometers on their wrists for a week. Based on their degree of activity, researchers categorised participants as weekend warriors, frequently active, or inactive.

A little over 42% of participants were weekend warriors. 34.7% were classified as inactive, compared to 24.4% who reported exercising frequently. In their data analysis, researchers took into account variables like age, educational attainment, and tobacco usage.

Regular exercise and weekend warrior activity both reduced the risk of AFib (an irregular heart rhythm), heart attacks, heart failure, and stroke. Similar hazards were reduced in both groups.

According to Dr. Shaan Khurshid, author of the study and director of the Demoulas Centre for Cardiac Arrhythmias at Massachusetts General Hospital, “both a weekend warrior type activity pattern and a more even activity pattern were each associated with similar reductions in risk of heart attack, heart failure, atrial fibrillation, and stroke as compared to inactive individuals.”

Limitations of the research and future directions

This study did have certain shortcomings in particular.

First, the study’s ability to generalize is constrained by the fact that it largely consisted of white, British subjects. Second, because the data only covered one week of activity, it’s likely that participants behaved differently than usual or altered their usual behavior as a result of being observed.

Researchers also point out that depending on the kind of exercise a person engages in, the accuracy of identifying moderate to strenuous physical activity can change. They employed a classification scheme that took into account a variety of activities, which might have affected the outcomes.

Finally, because this data collection occurred several years before the collection of accelerometry data, data on variables may have been incorrectly categorized.

The following study limitations were highlighted by Dr. Gregory Katz, an outside observer and assistant professor in the Department of Medicine at NYU Grossman School of Medicine’s Leon H. Charney Division of Cardiology as well as a cardiologist.

The major issue is that the study’s conclusions are somewhat constrained because participants weren’t monitored for long stretches of time in terms of tracking their exercise. They just used an accelerometer to evaluate them for seven days. This involves observing tens of thousands of people for a week of exercise and then keeping track of their health consequences for much longer than that. Thus, there is a limit to how broadly applicable this is.

Drs. Ellinor and Khurshid also identified the following areas as needing more study:

“We intend to examine if weekend warrior-style activities have comparable advantages over other human illnesses and diseases. Our findings might inspire more research on concentrated physical activity programs, which might be more useful and effective.

The importance of physical activity

As this study has shown, different people will engage in different amounts of physical exercise each week. The true problem is figuring out how to make time for physical activity in our daily life. For suitable physical activity suggestions, people should speak with their doctor. This is especially true if they are unaware of what levels and types of physical exercise are satisfactory.

Finding things you enjoy, working out with a friend, and designating certain times for exercise, according to the Centres for Disease Control and Prevention, could all help you become more active.

The important advantages of exercise were further emphasized by Dr. John Bhadorani, a board-certified interventional cardiologist at MemorialCare Heart & Vascular Institute at Saddleback Medical Centre in Laguna Hills, California, who was also not involved in the study:

Because it has a favourable effect on the heart and blood vessels, exercise is essential for cardiovascular health. Regular exercise improves cardiovascular health by strengthening heart muscle, reducing blood pressure, lowering bad cholesterol (LDL), and raising good cholesterol (HDL). Additionally, it helps people stay at a healthy weight, increases blood flow, and makes it easier for the body to use oxygen.

According to Dr. John Bhadorani, “This study suggests that this activity may not need to occur every day throughout the week but rather concentrated over 1-2 days as long as you are reaching the target of >150 minutes per week.”

Hearing aids may almost 50% lower the risk of dementia.

July 21, 2023 blogadmin Comments 0 Comment

The effect of hearing aids on slowing cognitive decline was studied in the largest clinical research to date.

Researchers discovered a 48% decrease in risk among those who were at an increased risk of dementia. The findings contribute to the body of knowledge on the relationship between hearing loss and cognitive decline.

According to the National Institute on Ageing, someone worldwide gets dementia, a group of illnesses that damage the brain. Also, result in cognitive decline and memory loss, every three seconds.

Alzheimer’s disease (AD) is the most prevalent form of dementia.

Dementia can occur for a variety of reasons, and there are a number of risk factors for dementia as well. Hearing loss is one of them. Hearing loss and a higher risk of dementia have been linked in previous studies.

The largest clinical experiment to look into whether a hearing loss therapy intervention can lessen a person’s risk for cognitive decline has now been completed. The results have been published by researchers from the Ageing and Cognitive Health Evaluation in Elders (ACHIEVE) study.

Researchers showed that using a hearing aid and getting support and counselling from an audiologist significantly reduced cognitive deterioration in individuals in a higher-risk subgroup by 48%.

Recognising those who use hearing aids

The study discovered differences in hearing aid usage based on geography, gender, and ethnicity.

Nearly 115,000 adults over the age of 66 who had hearing loss and insurance coverage from a significant. Also, private insurance firm between 2008 and 2016 were studied using data from these individuals.

Participants were followed up on by the team 3 years after their diagnosis and one year prior.

Men were more likely to use hearing aids if they had hearing loss. In actuality, 13.3 percent of men and 11.3 percent of women purchased hearing aids.

Additionally, 13.6% of white persons, 9.8% of African Americans, and 6.5 % of those of Latino descent received a hearing aid.

Nearly 37% of hearing-impaired Americans who wore hearing aids resided in the north-central region of the nation, compared to 5.9% of persons in the mountain states.

Those who wore hearing aids had an 18% decreased chance of receiving a dementia diagnosis within three years of a hearing loss diagnosis (including Alzheimer’s disease).

Hearing aid users had a 13 percent lower likelihood of receiving treatment for injuries sustained from falls and an 11 percent lower risk of receiving a diagnosis of depression or anxiety by the end of the three-year period.

The study’s findings, ACHIEVE

Participants in the ACHIEVE study range in age from 70 to 84, have mild to moderate hearing loss that is untreated, and do not have significant cognitive impairment. Four American locations were used to carry out the study.

977 individuals in all were recruited for the study. About 740 of them were recently recruited healthy community participants. The Atherosclerosis Risk in Communities (ARIC) study has about 240 participants.

Researchers found that participants in the ARIC group had more cognitive risk factors, poorer baseline cognitive scores, and a faster rate of cognitive deterioration over the course of the study’s three years than the other participants.

One group of participants underwent a three-year intervention that included receiving hearing aids, a self-management “toolkit” for hearing loss, and regular training and counselling with an audiologist.

Only speaking sessions with a health educator to address the prevention of chronic diseases were provided to the control group.

After three years, researchers discovered that ARIC study participants who received hearing aids and intervention had decreased the rate of their cognitive loss by 48%.

The ACHIEVE study’s co-principal investigator, Dr. Frank Lin, a professor at the Bloomberg School of Public Health and the Johns Hopkins University School of Medicine, said, “A 48% reduction in cognitive deterioration is significant, and we were happy to learn that the benefit was so big.”

How are hearing loss and cognitive deterioration related?

Dr. Lin claims that it has been well established for more than ten years by researchers that hearing loss significantly increases the risk of dementia and cognitive decline.

But he continued, “We didn’t know if treating hearing loss may actually slow cognitive deterioration and perhaps even cut the likelihood of dementia.”

Dr. Lin outlined three key factors that shed light on why dementia and hearing loss may be linked:

“First, hearing loss causes speech and sound to be muddled before they reach the brain, which makes it harder for the brain to understand the signals coming from the ear. The brain’s capacity to sustain thinking and memory is therefore reduced.”

Second, hearing loss depletes the areas of the brain that are normally activated by speech and sound, which can result in atrophy and modifications to the brain’s structure and function.

Thirdly, communication difficulties brought on by hearing loss might result in social isolation, another dementia risk factor, according to Dr. Frank Lin, co-principal investigator of the ACHIEVE project.

This is not the first study to look into the relationship between dementia, hearing loss, and hearing aids.

According to a 2022 study, wearing hearing aids may slow the cognitive impairment brought on by hearing loss.

Additionally, an observational study released in April 2023 discovered hearing loss was linked to a higher risk of dementia, and that utilising hearing aids may potentially help reduce that risk.

Additional proof that treating hearing loss enhances cognitive

Dr. Courtney Voelker, a board-certified neurotologist and the director of the Adult & Paediatric Cochlear Implant Programme at the Pacific Neuroscience Institute at Providence Saint John’s Health Centre in Santa Monica, California, commented on the study after reading it and said that it is an exciting study that provides additional proof that not only is hearing loss connected to cognitive decline as we age, but that we can also take action to prevent it.

According to her, there is growing evidence, which includes this study, that treating hearing loss aggressively can enhance cognition. This treatment may include cochlear implants or hearing aids, depending on the severity of the hearing loss. And it’s really exciting.

Dr. Voelker claimed that when discussing cognitive decline with her patients, she emphasises the significance of maintaining brain neuron activation and stimulation.

“And it’s very interesting patients really respond to this,” she added. “People who may have initially been reluctant to adopt hearing aids take the possibility of developing cognitive dementia very seriously when making their choice.” He also explains to patients why we allow people to go without hearing aids even though we would never allow someone to go without glasses if they had vision problems. Additionally, patients appear to connect with that parallel. According to neurotologist Dr. Courtney Voelker, “We want our hearing to be as crisp and clear as our vision is with glasses.”

Understanding hearing loss

The World Health Organisation (WHO) estimates that 20% of people worldwide have some form of hearing loss.

There are several reasons why someone could lose their hearing, including:

exposure over time to loud noises
hearing loss
destruction of the inner ear
a torn eardrum
a history of hearing loss in the family
some diseases, such meningitis, that raise the body’s temperature
a few medicines

Furthermore, hearing loss becomes more prevalent as we age, with the majority of cases typically happening beyond the age of 60.

Hearing loss can be either temporary or permanent, depending on the circumstances. There is currently no solution for age-related hearing loss, and it may get worse with time.

Sleeping well is incredibly important for lowering anxiety.

July 21, 2023 blogadmin Comments 0 Comment

Chronic stress can make some mental diseases, such as anxiety and depression, more likely.

According to a new study, sleep and adaptive emotion regulation techniques both have a significant impact on lowering the risk of anxiety and depression in those who are under a lot of chronic stress.

This study made use of the COVID-19 pandemic, which caused a lot of chronic stress in the population. Regardless of the cause, managing chronic stress is important.

The COVID-19 epidemic created a rare circumstance in which many people went through a period of prolonged stress. Researchers want to know how long-term stress like this affects mental illness and what elements can help mental health.

The relationship between adaptive emotion regulation techniques, also known as positive coping mechanisms, and sleep quality was investigated in a study that was published in the journal Cortex.

Both elements are beneficial in lowering rates of anxiety and sadness, according to scientists. In contrast to their premise, they discovered that the quality of sleep did not significantly affect how well emotion management strategies worked.

What function does sleep quality have?

In this study, sleep and mental health data gathered from the spring of 2020 through the autumn of 2020’s COVID-19 pandemic were analysed secondarily.

The initial goal of the study was to determine whether adaptive emotion management techniques are related to greater mental health.

Long-term mental health is enhanced through thought processes known as adaptive cognitive emotion control techniques. A good illustration would be “positive reappraisal,” which is the process of looking for the positive aspects of an event or circumstance.

Second, scientists wanted to know if the efficiency of adaptive emotion management techniques was affected by the calibre of sleep. The COVID-19 pandemic was used as a naturally occurring and persistent stressor while they examined these factors.

Strategies for emotional management are crucial.

There were 1,600 adult participants in the study. The participants filled out online forms to submit information, including crucial demographic data. They also answered questions about general anxiety, despair, and sleep hygiene, as well as techniques for controlling emotions.

Based on data analysis, the researchers discovered that lower scores for anxiety and sadness were connected with greater usage of adaptive cognitive emotion control techniques.

Additionally, they discovered a link between claims of better sleep quality and lower anxiety and depressive disorder scores.

In terms of the connection between adaptive cognitive emotion regulation strategies and sleep quality, they discovered that persons who reported getting more restful sleep used these strategies more frequently.

Their final model, which took into account the quality of the sleep, revealed that employing adaptive cognitive emotion control techniques did not significantly predict the consequences of anxiety.

In other words, the quality of sleep did not seem to affect how successfully positive coping techniques reduced depression and anxiety. Regardless of the quality of sleep, the positive control techniques still demonstrated benefits for mental health.

Sullivan provided a nuanced explanation of these findings:

We did discover that using positive coping mechanisms more frequently was linked to fewer depressive and anxious symptoms. Additionally, fewer signs of anxiety and despair were linked to higher sleep quality. However, contrary to what we had anticipated, employing healthy coping mechanisms to lessen sadness and anxiety symptoms did not rely on getting enough sleep.

Findings are not as unexpected as they may appear

Dr. Lindsay Oberleitner, a licenced clinical psychologist and the education director of SimplePractice, who was not engaged in this study, offered her thoughts on the findings.

Contrary to expectations, she said, “cognitive emotion regulation strategies and sleep quality did not interact in their relationship to depression and anxiety.”

However, she added, this might not be as shocking as it initially appears to be.

“If we take a step back from the current study, this might not come as much of a surprise. We are aware that different people experience depression and anxiety in different ways due to complicated circumstances”. According to Dr. Lindsay Oberleitner, only a small part of emotion management techniques use adaptive cognitive strategies, and sleep is only one physical health factor that affects mental health.

Limitations of the study and future research

It is nonetheless important to be aware of this study’s limitations. Participants’ self-reporting, which is not always reliable, was used by researchers.

They observe that subjectively evaluated sleep quality is frequently poorer than what people report. They could only test sleep quality and adaptive cognitive emotion regulation technique once, thus they were unable to track changes that might have taken place over the course of the study.

Additionally, the authors had more data on depression than anxiety. The study lacked the capacity to detect any potential minor interaction effects.

They were unable to determine which cognitive emotion control method or combination was more effective due to the measurements they employed, as well as how these strategies worked together.

The majority of the white, educated female participants in the study were from the United States. Specific confounders could not be accounted for, and data was gathered online. All of these characteristics limit how broadly the study’s findings can be applied and point to the need for more diverse research in the future.

The COVID-19 pandemic presented a unique form of stress, therefore it is challenging to relate this study to other types of persistent stress and the ensuing mental health results, according to the study authors.

Since the COVID-19 pandemic was undoubtedly a particularly stressful circumstance, she said, “it would be beneficial to replicate these results in the context of other protracted stressful events.”

Additionally, she continued, “as we examined a variety of positive coping mechanisms together, it may be crucial in the future to see how particular mechanisms, like positive reappraisal (rethinking the circumstance in a positive light) and putting into perspective (i.e. considering the bigger picture), are related to both sleep quality and depressive and anxiety symptoms.”

How to deal with persistent stress?

Regardless of what causes it, managing stress requires action.For mental wellness, a trusted source is essential. This may entail making efforts to live a healthy lifestyle, asking friends for aid, and knowing when to seek the assistance of a mental health professional.

The World Health Organisation (WHO) adds that keeping a daily schedule and limiting time spent on social media can both help with stress management.

In Phoenix, Arizona, at Cora Health Solutions, Betsy Serrano, a board-certified psychiatric mental health nurse practitioner who was also not engaged in the latest study, provided the following advice for productive stress management:

“There are some straightforward exercises that can help reduce mild tension and anxiety. By releasing feel-good endorphins, physical activity releases stress-relieving hormones that help to calm the mind.” When feeling anxious, eating well, limiting caffeine intake, practicing yoga and meditation, as well some smartphone apps like Calm, are all quite beneficial. However, if your stress levels are so high that they’re interfering with your daily activities, you should think about seeking counselling and, if necessary, medication, according to mental health nurse practitioner Betsy Serrano.

Are Ketamine injections effective for resistant depression?

July 21, 2023 blogadmin Comments 0 Comment

Participants in clinical trials with treatment-resistant depression got placebo or racemic ketamine injections twice weekly for a month.

With the use of ketamine, about one in five patients had all of their symptoms go, and nearly a third had at least a 50% improvement.

A total of six clinical mood disorder centers from Australia and one from New Zealand collaborated on the study.

More and more academics are investigating the use of psychedelics, a class of drugs that alter consciousness, as a potential depression cure. The drug ketamine, which has been used as an anesthetic for many years, is of particular interest to many.

A recent study comparing the effectiveness of racemic ketamine vs a placebo in easing the symptoms of treatment-resistant depression was published in the British Journal of Psychiatry.

Depression that does not improve after receiving two or more forms of treatment is referred to as treatment-resistant depression.

What variations of ketamine are there?

The commercially produced nasal spray Spravato (ketamine) was approved by the Food and Drug Administration (FDA) in 2019 for adults with treatment-resistant depression and for individuals with major depressive disorder who have acute suicidal ideation.

In the US, racemic ketamine is permitted for use as anaesthetic. In addition, doctors prescribe it “off-label”—that is, for a condition other than the one for which the FDA has given its approval—to treat depression.

Additionally less expensive than Spravato is racemic ketamine.

Participants in the current trial, which was directed by academics at the University of New South Wales Sydney (UNSW) and the associated Black Dog Institute, got injections of racemic ketamine or a placebo twice a week.

Largest clinical trial to date

According to Medical News Today, the trial’s principal investigator, Dr. Colleen Loo, a clinical psychiatrist and professor of psychiatry at UNSW, started examining ketamine’s effects on depression in 2011. She had previously researched how ketamine was used in anesthesia for electroconvulsive treatment (ECT).

She said that this research experiment, which compares racemic ketamine with placebo for treatment-resistant depression, is the largest of its kind.

Dr. Loo further emphasized that one-fourth of the subjects had previously undergone ECT treatment but had not shown improvement.

“ECT is a highly effective treatment for severe and treatment-resistant depression, so it means that these people had high-end treatment-resistant depression,” she argued.

Because it is extremely difficult to get any treatment to work once someone has received ECT and is still ill, this group is typically left out of the research. According to Dr. Colleen Loo, this study “provides evidence of the efficacy of ketamine, at least the racemic form, in treating depression with a high level of treatment resistance.”

Dr. Loo finds it significant that racemic ketamine injections were used in the trial rather than more costly and time-consuming infusions, demonstrating the efficacy of this less expensive option.

Study on ketamine for adult depression

The Ketamine for Adult Depression (KADS) research was a trial in which 184 patients with treatment-resistant depression participated. Six clinical mood disorder centres in Australia and one in New Zealand participated in the investigation.

Participants must have applied by April 2020, with the application period opening in August 2016.

Dr. Loo told that when the pandemic struck, researchers decided to stop recruiting new subjects for the trial. Originally, they had hoped to enroll more people.

Participants had a serious depressive disorder for at least three months and were 18 years of age or older. Furthermore, patients had to have received an inadequate response with at least two antidepressants.

Before beginning the trial, the participants had to have been taking the same dosage of their current antidepressant for at least four weeks. Additionally, they had to have a Montgomery-Sberg Rating Scale for Depression (MADRS) score of at least 20.

“Good safety profile” for injections of ketamine

Racemic ketamine or midazolam injections were given to participants at random. Midazolam is frequently used to assist patients unwind before surgery.

For four weeks, individuals received injections into their abdomen walls twice each week with at least three days in between each treatment.

According to Dr. Loo, the participants didn’t seem bothered by the abdominal injections.

“The injection used a very small needle to inject ketamine under the skin,” she claimed. “It can be done anywhere — arm, leg, abdomen — but we did it in the abdomen because there is usually more fat there under the skin, so it is more comfortable.”

Participants and researchers who administered the medication were unaware of who received racemic ketamine. Because midazolam also induces sleepiness, like ketamine, it was chosen as the placebo because it helped prevent participants from knowing which medication they would get.

Initially, a fixed dose of either 0.025 milligrammes per kilogramme of midazolam or 0.5 milligrammes per kilogramme of racemic ketamine was administered randomly to 73 subjects.

The authors of the study report that during a routine Data Safety Monitoring Board meeting, “a revisiting of drug dosage was recommended as no participants in the entire masked sample had remitted and the safety profile was good,”

As a result, the dosage was altered, and 108 individuals were randomly assigned to receive flexible doses of either midazolam or ketamine in a second group. Implementation of response-guided dosage. Racemic ketamine dosages were increased to 0.6 milligrammes per kilogramme, 0.75 milligrammes per kilogramme, and 0.9 milligrammes per kilogramme in sessions 2, 4, and 6 if patients had not improved by 50% from baseline scores. Elevated doses of midazolam were given to participants as well.

If they received at least one injection, they were considered for the trial, however, Most” people received all eight dosages.

Monitoring safety closely yields fruitful outcomes.

The majority of individuals in the flexible dosing group increased their racemic ketamine dosage to the maximum level. Dr. Loo claims that this aspect of the study turned out to be significant. “It showed that individual dose adjustment, up to the dose that each person requires for a response, is really important for getting the best outcomes,” the researcher added.

The Ketamine Side Effect Tool (KSET) was utilised by researchers to better understand the short- and long-term side effects of various racemic ketamine therapies.

Participants were checked on again four weeks following the last injection. The open-label therapy phase was open to participants who had relapsed; this means that they would be aware of the treatment they are getting.

“The study used a very detailed and comprehensive approach to safety monitoring, monitoring for cumulative effects between treatments, not just in the two hours after each treatment, or just enquiring at the end of the four weeks,” stated Dr. Loo.

The researchers state in the trial publication that “if ketamine treatment is halted after 4 weeks, the benefits are not sustained for all remitters and that ongoing treatment should be considered.”

According to the researchers, “most” individuals decided to start open-label treatment at the conclusion of the four weeks.

30% of subjects had a 50% improvement in symptoms

After a month of injections, 1 in 5 subjects getting flexible doses of racemic ketamine had completely recovered from their symptoms, compared to 2% of participants receiving placebos.

Compared to 4% of those who received a placebo, nearly 30% of those who received ketamine saw symptom improvements of at least 50%.

A 20% remission rate, which Dr. Loo deemed “quite good” for treatment-resistant depression, did not surprise her.

The outcomes are actually very positive, according to Dr. Loo. “Ketamine was still very effective, with an impressive 10 [times] difference compared to placebo,” according to the study. “Even in people with depression at the high end of treatment resistance excluded from most prior studies.”

The scientists want to develop the KSET further and run bigger, more extensive studies with generic ketamine in the future.

Heart failure: An Important link with cognitive impairment.

July 20, 2023 blogadmin Comments 0 Comment

Heart failure affects more than 64 million people globally. One of the most frequent complications in heart failure patients is cognitive impairment.

Heart failure may cause cognitive decline because, according to Columbia University researchers, there is a little calcium leak inside the brain’s neurons.

Additionally, researchers have created an investigational medication that aims to ‘plug’ the calcium leak and halt the course of heart failure.

Heart failure, an incurable cardiovascular disorder where the heart cannot effectively pump blood throughout the body, affects about 64 million people globally.

Complications include shortness of breath, arrhythmia, and kidney problems. Also, fluid retention in the lungs, belly, feet, and legs is more common in those with heart failure.

Additionally, one frequent complication in persons with heart disease is cognitive impairment.

A little calcium leak inside the brain’s neurons, according to Columbia University researchers, may be the reason heart failure can result in cognitive impairment.

In addition, researchers have created an experimental medication to “plug” the calcium leak and perhaps reduce the development of heart failure.

What is cognitive dysfunction?

Cognitive impairment is also known as mild cognitive impairment. It happens when a person struggles to perform routine tasks that call for mental abilities like memory and thought.

Cognitive disability examples include:

forgetfulness
missing events on the calendar
not knowing how to travel to frequented locations
difficulty understanding a talk
decision-making challenges
failure to follow through on commitments or directions

People who have modest cognitive impairment could also go through emotional changes like despair, anxiety, and rage.

Cognitive impairment can be brought on by a variety of conditions, including infections, prescription drugs, and other diseases.

A increased chance of developing other types of dementia, such as Alzheimer’s disease, exists in those with mild cognitive impairment.

How does brain dysfunction may affect cognition?

The team decided to investigate a potential link between heart failure and cognitive decline. Based on what they already knew about the ryanodine receptor type 2 (RyR2)/intracellular Ca2+ (calcium release channel), Dr. Andrew R. Marks, chair of the Department of Physiology & Cellular Biophysics at Columbia University Vagelos College of Physicians and Surgeons and lead researcher of this study explained.

Both the heart and the brain have the RyR2 channel, thus he said, “I reasoned that since the channel is leaky in the heart due to systemic stress of heart failure it might also be leaky in the brain.”

In heart muscle, there is an encoded protein called RyR2. It contributes to the delivery of that specific mineral to the cardiac muscles as a component of the intracellular calcium channel.

Calcium is essential for both heart and brain function, Dr. Marks noted. “Calcium is required to activate muscle contraction in the heart and for signaling in the brain.”

Testing the theory of the heart-brain relationship

Dr. Marks and his team tested their theory in this study using a mouse model. Researchers discovered that calcium leakage in the brain’s neurons caused cognitive impairment in rats with heart failure.

Scientists also looked at the brains of heart failure victims who had passed away. They looked at those brains and discovered leaky calcium channels, which may have contributed to cognitive impairment in those people.

Since heart failure is progressive, clinicians may want to closely examine their heart failure patients for cognitive impairment and keep track of this, according to Dr. Marks’ research. “The doctors could determine whether their patient’s cognitive impairment is affecting their capacity to comply with medical advice and take their medications.”

Are calcium leaks treatable by doctors?

Dr. Marks and his team discovered throughout the study that an investigational medication called Rycals created by Marks’ group. It could be used to “plug” the calcium leak and possibly delay the onset of heart failure.

“Rycals fix the leak in RyR channels and are in clinical trials at the Mayo Clinic and at the AMC in Amsterdam for an inherited form of exercise-induced sudden death,” stated Dr. Marks. In a year or two, depending on the outcome of this experiment, they might be available.

A broad unifying hypothesis?

About this study, Dr. Richard Wright, a cardiologist at Providence Saint John’s Health Centre in Santa Monica, California, who was not involved in the study, remarked.

He applauded the researchers for finally developing a comprehensive, all-encompassing theory of various disease states after years of research.

Dr. Wright said, “People with chronic heart failure are weak and have respiratory problems; this has long been known. As this article noted, they frequently exhibit cognitive impairment in comparison to their classmates.”

Here, Dr. Marks’ team is attempting to develop a unified theory to account for all these many changes that take place in heart failure patients, and I believe they have done so. Dr. Richard Wright stated, “I believe this idea that calcium excess is a unifying mechanism to explain not only the heart’s dysfunction but skeletal muscle dysfunction, diaphragm dysfunction, and as the article’s main thesis, brain dysfunction as well.”

The beginning of a new era is upon us.

Dr. Wright remarked that he was thrilled to learn of a substance created in the lab of the study team that has been demonstrated to favourably effect these alterations.

We are at the beginning of a new era, which I would refer to as the period of designer molecules, he remarked. “We’ve seen it in hypertrophic cardiomyopathy and amyloidosis already, where you can design molecules that change pathologic changes of proteins.”

They have compounds created in their lab to prevent alterations that help prevent calcium excess in neurons, heart cells, and skeletal muscle cells. This could have a significant impact on the results of our research.

Dr. Wright did point out that additional research is still required because the majority of the results in this article came from a mouse model.

Humans are not mice, he continued, so “sometimes we get misled.” However, they’ve done a great job of avoiding that and gone to the bother of using chunks of autopsied brains to support their claim, which I think is quite real.”

Other study limitations include the tiny number of human brains examined by the researchers and the fact that the study’s control group consisted of participants who were significantly younger than those who had suffered from heart failure and cognitive deterioration.
