  • A research of a lot more than 50 percent a million younger grown ups located that melancholy is linked to a higher hazard of cardiovascular illness and lousy cardiovascular well being.
  • Individuals who described often currently being frustrated experienced a drastically bigger danger of coronary heart challenges.
  • Depression is recognised to lead to unhealthy behaviors that might have an affect on one’s heart, and getting heart problems can direct to despair, a problematic cycle.

A examine of in excess of 50 {cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} a million individuals aged 18 to 49 finds a strong association among despair and cardiovascular disease and inadequate cardiovascular wellbeing.

Examine participants who documented acquiring 1 to 13 times of poor mental well being in the previous 30 days experienced 1.5 occasions the cardiovascular ailment hazard of these reporting no this kind of times.

For these reporting 14 to 30 days of very poor mental wellbeing, the chance of cardiovascular disorder was even better: 2.3 situations the risk of people today reporting no these kinds of days.

The scientists also uncovered that the relationship in between despair and coronary heart troubles was unaffected by intercourse or urban/rural area.

According to the Entire world Wellness Organization (WHO), around 5{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} — an believed 264 million men and women in 2017 — of the world’s populace are impacted by depression.

One particular in five of those people in the examine documented possessing depression.

The study suggests that the link could start in early adulthood.

The new study seems in the Journal of the American Heart Association.

“Being in a depressive condition or feeling down can make one particular skip a meal or overindulge in comfort and ease foodstuff, have slumber problems, smoke, or not want to workout, and these are all hazard elements for bad cardiovascular health and cardiovascular illness,” stated the study’s direct creator Dr. Yaa A. Kwapong.

The authors pointed out that the cross-sectional review will take no situation on regardless of whether depression causes heart challenges or that coronary heart issues guide to melancholy. It is possible both of those are correct, commonly.

A human being with diagnosed or perceptible coronary heart problems also may gravitate toward equivalent behaviors.

Dr. Kwapong stated suboptimal coronary heart health and fitness in the research was described as two or more of the next hazard aspects for individuals who had not so far been diagnosed with cardiovascular disorder:

  • hypertension
  • diabetic issues
  • being a smoker
  • obesity
  • superior cholesterol
  • physical inactivity
  • not eating adequate fruits and vegetables

Dr. Kwapong mentioned despair might also have a more immediate result on coronary heart wellbeing:

“Physiologically, melancholy or temper conditions boost one’s pressure hormones, inflammation, and have an effect on glucose and lipid homeostasis, which may well all with time direct to cardiovascular illness.”

Dr. Yu-Ming Ni, cardiologist of Non-Invasive Cardiology at MemorialCare Coronary heart and Vascular Institute at Orange Coast Health care Center in Fountain Valley, CA, was not included in the analyze. He supplied an illustration of depression’s physiological action on the heart.

Dr. Ni described “broken-coronary heart syndrome” as a issue that happens after critical trauma, normally ahead of enough time for harmful behaviors to take their toll. Most broken-coronary heart clients can be productively treated.

“They come into the hospital, the heart is not squeezing incredibly perfectly, and they can be quick of breath, have chest pain. Drinking water can accumulate in the system, and we have to give drugs to drain the h2o out and make improvements to the coronary heart purpose,” Dr. Ni explained. “It’s just yet another typical example of how grief and psychological trauma can affect the hazard for heart sickness.”

Although the syndrome’s mechanics stay unclear, Dr. Ni mentioned the surge of hormones in the sympathetic anxious system that can take place with intense emotional duress. He also suspected improved amounts of cortisol are included.

At the similar time, he asserted that the new examine builds on the insights introduced in the global INTERHEART analyze executed concerning 1999 and 2003. That task encompassed all the world’s locations and main ethnic groups. It observed that globally 90{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the possibility of coronary heart attacks could be attributed to modifiable chance factors.

For persons with any of the poor coronary heart wellbeing chance aspects listed above who are vulnerable to despair, the review underscores the worth of in search of qualified assist with one’s psychological health.

As Dr. Kwapong noted:

“This analyze highlights the intersection of psychological health and cardiovascular overall health and provides to the body of literature about the relevance of psychological/ psychological wellbeing in advertising and marketing cardiovascular Health and fitness.”

The American Coronary heart Association’s Life’s Essential 8 emphasizes psychological health, included Dr. Kwapong.

Dr. Ni recommended that one particular can test to catalog the despair-triggering stresses in one’s existence.

It’s not a issue of how a great deal strain you have, but how it affects you, he reported.

Occasionally, he pointed out, we get applied to this kind of stressors, whether we like them or not. Dr. Ni also pointed out the advantage of having a healthy social circle and psychological support if achievable.

It is also a very good idea to enable one’s health practitioner or cardiologist know about the psychological issues a person may possibly be getting, he included.

As a cardiologist, he said:

“I want to get to know you improved. I want to know how you are dealing with [your] clinical problems, and how you’re managing issues at household since that will support me to know how finest to take care of you.”

Ultra-processed foods may increase ovarian and brain cancer risk

Ultra-processed foods may increase ovarian and brain cancer risk

  • For many years, scientists have linked a healthy diet to a lowered risk for certain diseases.
  • Researchers from Imperial College London found that eating ultra-processed foods increases a person’s risk for developing cancer overall, specifically ovarian and brain cancers.
  • Scientists also found eating those foods heightens a person’s risk of dying from all cancers, especially ovarian and breast cancers.

Doctors have known for some time now that what we eat has a direct effect on our overall health.

The body requires specific nutrients to perform its routine tasks. And a healthy diet is linked to lowering a person’s risk for certain diseases, including cardiovascular disease, type 2 diabetes, and cancer, as well as promoting better mental health.

Now, researchers from Imperial College London say eating ultra-processed foods increases a person’s risk for developing all cancers, specifically ovarian and brain cancers. And these foods also heighten a person’s risk of dying from cancers, especially ovarian and breast cancers.

The study was recently published in the journal eClinical Medicine.

Ultra-processed foods make up the fourth category of the NOVA food classification system.

According to this classification system, a food is considered ultra-processed if it is:

  • an industrial-made food with five or more ingredients
  • made entirely or mostly from substances extracted from foods, such as oils, fats, sugars, and starches
  • includes food substances not normally found in culinary preparations, like hydrogenated oils and modified starches
  • features additives whose main purpose is to imitate aspects of natural foods such as flavors, colors, and emulsifiers

Examples of ultra-processed foods include:

  • sodas and “energy” or sports drinks
  • packaged cookies
  • candies
  • pre-prepared pizza and packaged meats
  • sweetened and flavored yogurts
  • “instant” soups and other mixes
  • sweetened juices
  • baked goods made with hydrogenated vegetable fat, emulsifiers, and other additives

Previous research shows eating ultra-processed foods increases a person’s obesity risk and can accelerate a person’s biological aging.

Additionally, consuming ultra-processed foods has been linked to a higher risk of heart disease, colorectal cancer, dementia, and all-cause mortality.

For this study, researchers used U.K. Biobank records to analyze the diets of 200,000 middle-aged adults. Scientists reviewed participants’ health over a 10-year time span, looking to see if they specifically developed 34 different types of cancer.

Upon review, the research team found people with higher consumption of ultra-processed foods had a greater risk of developing cancer overall.

For every 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increase in ultra-processed food in a person’s diet, that person had a 2{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increased risk of developing cancer overall.

Additionally, researchers found for every 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increase in ultra-processed food consumption, a person increased their overall cancer death risk by 6{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}.

“The findings of this study on overall cancer risk are in line with what we know about the importance of a healthy diet in reducing our cancer risk,” Dr. Eszter Vamos, a clinical senior lecturer in the School of Public Health at Imperial College London and lead/senior author of this study told Medical News Today.

“There are many potential ways ultra-processed foods may increase cancer risk, and we need further research to better understand these,” she continued.

“UPFs have poor nutritional quality, are often high in salt, sugar, and unhealthy fats and low in fiber, and promote obesity — which is in itself a risk factor for many types of cancers. Ultra-processed foods may also contain potentially cancer-causing agents such as some controversial food additives, chemicals generated during food processing, and chemicals from packaging.”
— Dr. Eszter Vamos

In addition to overall cancer risk, Dr. Vamos and her team also found for every additional 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of ultra-processed foods in the diet, a person increased their risk of developing ovarian cancer by 19{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} and dying from it by 30{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}.

“This is the first study to assess associations of ultra-processed food consumption with many different types of cancers, including ovarian cancer,” Dr. Vamos explained, adding: “We need further studies from other populations to confirm these findings.”

“However, previous studies suggest that diets high in unhealthy fats and low in vegetables may increase the risk of ovarian cancer,” she said.

“Ultra-processed foods may also promote inflammation that could contribute to cancer risk. Furthermore, some potentially cancer-causing agents such as acrylamide, which may be generated during processing, have been implicated.”
— Dr. Eszter Vamos

Researchers also found for every 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increase in ultra-processed foods in a person’s diet, they raised their breast cancer mortality rate by 16{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}.

Dr. Parvin Peddi, a medical oncologist and director of Breast Medical Oncology for the Margie Petersen Breast Center at Providence Saint John’s Health Center, California, who was not involved in the study, reiterated that breast cancer has a known correlation with people who are overweight as they can have higher levels of estrogen, which promotes risk breast cancer.

“We do know that people who have ‘unhealthy habits’ like dietary habits, meaning they eat more fatty or they are overweight, and perhaps now ultra-processed foods, have an increased risk of breast cancer.”
— Dr. Parvin Peddi

Medical News Today also spoke with Dr. Steve Vasilev, a board certified integrative gynecologic oncologist and medical director of Integrative Gynecologic Oncology at Providence Saint John’s Health Center and Professor at Saint John’s Cancer Institute in Santa Monica, California, about this study and how ultra-processed foods may cause increased cancer risk. Dr. Vasilev was not involved in the study.

He said the “old school thought” was that various toxins from food processing, as well as added preservatives, lead to genetic mutations that cause cancer.

“That’s probably true to some extent. However, we now know since the Human Genome Project that there’s something called epigenetics, which basically is a study that looks at how genes are turned on and off. For example, if tumor suppressor genes are turned off, it will lead to diseases like cancer,” Dr. Vasilev explained.

However, he said that even if a person is born with the BRCA1 gene that increases their risk for developing breast and ovarian cancer, that does not necessarily mean that person will get one of those diseases. The epigenetics, he explained, leads to that gene being switched on or off in the body.

“So you do have a proactive ability to modulate which genes are turned on and off in your body. And what influences those, some of it is literally the toxins that accumulate from the preservatives and things like that in ultra-processed foods,” Dr. Vasilev added.

So how can people improve their diet to help decrease their cancer risk?

Kate Cohen, a registered dietitian at the Ellison Institute for Transformative Medicine at Providence Saint John’s Health Center in Santa Monica, California, told Medical News Today that while correlation is not causation, medical experts know that around 50{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of cancers can be prevented through diet and lifestyle changes.

“Hence diet is a controllable risk factor that every single one of us can and should take ownership of. You can’t control the physiology of how your body responds to food, but you can control what food you put into your body.”

Cohen, who was not involved in the study, also said this study gives doctors more ammunition to explain, encourage, instruct, and direct patients that a healthy diet has a direct effect on so many different health conditions.

“And now we see that breast, ovarian and other cancers may be on that list. If patients are at higher risk of developing any cancer — man or woman — doctors should be jumping up and down about this, as well as familiarizing patients with the other modifiable risk factors for cancer. We haven’t cured cancer, but we can cure bad diets.”

Higher lifetime estrogen levels tied to 13{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk

Higher levels of lifetime estrogen are linked to a lower risk of stroke, new research finds. Image credit: Chen Liu/EyeEm/Getty Images.
  • Researchers investigated the effects of lifetime estrogen exposure on stroke risk.
  • They found that higher levels of lifetime estrogen exposure in women were associated with a lower risk of stroke.
  • Further research is needed to understand how higher estrogen exposure confers protection from stroke.

A stroke occurs when blood is blocked from reaching the brain or a blood vessel in the brain bursts.

Stroke is the second-leading cause of death around the world, and its incidence increased substantially between 1990 and 2019 globally, including a 70{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increase in the number of incident, or first-ever, strokes.

Some studies suggest that higher estrogen levels may protect against stroke. Research shows, for example, that young women have a lower stroke risk than men, and that this risk increases after menopause, when estrogen production reduces.

Understanding more about stroke risk factors could improve preventative care and lead to improved treatment options.

Recently, researchers examined the link between lifetime cumulative estrogen exposure and stroke risk among postmenopausal women in China.

They found that women with the highest lifetime estrogen exposure had the lowest stroke risk.

The study appeared in Neurology.

For the study, researchers examined healthcare data from 122,939 postmenopausal women without prior stroke at baseline from the China Kadoorie Biobank study. Participants were aged between 40 and 79 years and were followed for an average of 8.9 years.

They were asked to provide information about their reproductive history, including the age of puberty onset, the age at which menopause started, and the number of pregnancies they had. They also provided information on their use of contraceptive pills.

The women were then split into four groups according to their reproductive lifespan (RL), or the number of years between puberty onset and menopause. Those in the shortest RL group had up to 31 reproductive years, whereas those in the longest RL group had 36 years or more.

The researchers also collected data on stroke incidence. During the study, they recorded 15,139 cases of new-onset stroke.

The researchers found that 13.2{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of women in the longest RL group had a stroke, compared to 12.6{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of women in the shortest RL group.

However, after adjusting for factors including smoking, age, and physical activity, they found that, in fact, participants in the longest RL group had a 5{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk for all types of stroke than those in the shortest group.

In particular, when they looked at different stroke subtypes, they found that those in the longest RL group had a 13{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk for intracerebral hemorrhage compared to those in the shortest RL group. Intracerebral hemorrhage is the most fatal kind of stroke which occurs when blood vessels burst in the brain.

Women in the longest RL group also had a 5{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk for ischemic stroke — when the blood supply to the brain is interrupted or reduced — compared to the shortest group.

The researchers also found that oral contraceptive pill use duration, which is linked to increased estrogen levels, was associated with a lower risk of stroke.

Those with fewer stillbirths, miscarriages, and terminations were also less likely to develop stroke.

“The link between reproductive lifespan, endogenous/ exogenous estrogens and risk of stroke in women is poorly understood,” Dr. Bharti Manwani, assistant professor of vascular neurology with McGovern Medical School at UTHealth Houston, not involved in the study, told Medical News Today.

“Preclinical studies have shown estrogen to be a profound neuroprotective agent, while clinical trials of estrogen replacement therapy in postmenopausal women failed to show benefit,” she noted.

Dr. Alex Polyakov, associate professor and gynecologist at the University of Melbourne in Australia, also not involved in the study, agreed that the exact mechanisms behind estrogen’s effects on stroke risk are not fully understood.

He added that: “Further research is needed to better understand the biological, behavioral, and social factors that may contribute to the link. Some potential mechanisms include the ability of estrogen to influence blood flow and the formation of blood clots, which can play a role in stroke risk.”

“Estrogen may also have protective effects on the brain and cardiovascular system. Estrogen is known to have a number of beneficial effects on the cardiovascular system, such as improving blood lipid levels, decreasing oxidative stress, and promoting blood vessel health. The relationship between estrogen levels and stroke risk is complex and can vary depending on various factors such as age, genetics, lifestyle, and hormone replacement therapy.”

– Dr. Alex Polyakov

In the Neurology paper, the researchers concluded that cumulative estrogen exposure from reproductive factors could be a useful indicator of a woman’s risk of different types of stroke after menopause.

We asked study author Dr. Peige Song of the School of Public Health at Zhejiang University School of Medicine, Hangzhou, China, about the study’s limitations.

She told us that “[s]ome limitations of the study include potential recall bias in the collection of reproductive factor information, and the inability to control for other factors that may impact estrogen exposure and stroke risk, such as genetics, early life experiences, and diet.”

“The major limitation of this study is that estrogen exposure was measured indirectly rather than through direct blood levels,” Dr. Adi Iyer, a neurosurgeon and neurointerventional surgeon at the Pacific Neuroscience Institute at Providence Saint John’s Health Center in Santa Monica, CA, not involved in the study, also told MNT.

Dr. Polyakov added as the study is observational, it can only establish a correlation and not causation. He further noted that the study was conducted only on Chinese patients, and so its findings may not apply to people from other populations.

“The implications of this study for the future of women’s health are very intriguing, and more studies regarding the cerebrovascular protection value of a higher lifetime estrogen exposure is needed,” Dr. George B. Branning, board-certified physician specializing in obstetrics and gynecology, from Biote Medical Faculty, not involved in the study, told MNT.

“Although hormone replacement therapy [HRT] is usually suggested for patients who want relief of their symptoms such as hot flashes, night sweats, weight gain, and mood changes, studies have shown that HRT is essential to lifetime functional bone health, sexual health, and cognitive protection. These new study results indicate we can perhaps add stroke protection to this growing list of benefits,” he added.

Dr. Manwani agreed that it is essential to know that longer cumulative estrogen exposure decreases stroke risk in postmenopausal women. She noted, however, that age at puberty onset or menopause is beyond a woman’s control.

“Therefore, it is important for clinicians to risk-stratify women with decreased estrogen exposure/ lower reproductive lifespan and work on controlling/ treating their other modifiable vascular risk factors aggressively, for example, hypertension, hyperlipidemia, atrial fibrillation, diabetes mellitus, smoking,” she explained.

“[These findings] also open up another debate about the role of estrogen in stroke. Is it good or bad? More studies on estrogen replacement therapy are needed to identify if increasing the estrogen exposure by use of hormone therapy would be beneficial,” she concluded.

Omega-3 fatty acids from fish may reduce kidney disease risk

Omega-3 fatty acids from fish may reduce kidney disease risk

Omega-3s from seafood could improve kidney health, research shows. Pham Hung/Getty Images
  • Chronic kidney disease affects 1 in 10 people worldwide, and if left untreated, it can lead to kidney failure.
  • Diet, exercise, and maintaining a healthy weight can all help to prevent or manage the condition.
  • A new study suggests that by including fish-rich omega-3 fatty acids in their diet, people can reduce their risk of chronic kidney disease.

Chronic kidney disease (CKD) affects more than 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the global population at around 850 million people. It is more common in older people, and risk factors include diabetes, high blood pressure, heart disease, and a family history of kidney failure.

According to the National Institutes of Health, more than 37 million adults in the United States may have chronic kidney disease.

Damage to the kidneys can happen over a long period of time, often causing no symptoms at first. Eventually, the kidneys cannot filter blood properly, leading to edema, or fluid retention, because the kidneys cannot get rid of extra fluid and salt.

People with CKD are at higher risk of cardiovascular disease and death.

Managing blood pressure and blood sugar levels is key to keeping your kidneys healthy. Being active, maintaining a healthy body weight, and eating a healthful diet are also important in both preventing and managing CKD.

Animal studies have suggested that omega-3 fatty acids may benefit kidney function.

Now, researchers from the University of New South Wales in Sydney have found that omega-3 from seafood is associated with a moderately lower risk of chronic kidney disease and a slower decline in kidney function.

The study was published in the BMJ.

The study was a part of the Fatty Acids and Outcomes Research (FORCE) consortium of studies. FORCE was set up to understand the relationships between fatty acids from our diet and metabolic processes, using data from multiple studies.

“This is an interesting study of diet potentially having a direct effect on disease progression. […] The methodology of this pooled analysis is good—more precise and avoids measurement errors related to self-report.”

— Dr. Eamon Laird, visiting research fellow, Trinity College, Dublin, who was not involved in the study.

The researchers analyzed data from 19 studies from 12 countries to assess the association between long-chain omega-3 polyunsaturated fatty acids (n-3 PUFAs) and CKD.

They estimated glomerular filtration rate (eGFR) at baseline and follow-up visits and defined incident CKD as eGFR that decreased to below 60ml/min/1.73 m2. eGFR measures how well the kidneys are removing waste from the body. The healthy range is 90-120 ml/min/1.73 m2.

The 25,570 participants were ages 49–77 years at the beginning of the study. Overall, 4,944 (19.3{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}) developed incident CKD during the follow-up period of, on average, 11 years.

People who had higher levels of seafood-derived omega-3 in their diet had an 8{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk of incident CKD. Those with total seafood n-3 PUFA levels in the highest fifth had a 13{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} lower risk of CKD compared with those in the lowest fifth.

The researchers found this protective association with three individual omega-3s from seafood, including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and docosapentaenoic acid (DPA).

Dr. Shree Mulay, CEO and nephrologist at The Kidney Experts, PLLC, who was not involved in the study, welcomed the study, but urged some caution, especially in people who already have CKD.

“It’s exciting to explore if eating fattier seafood could lead to increased PUFA intake and slower CKD progression. However, it’s essential to be wary as many of these fish are packed with phosphorus — a mineral that nephrologists work hard to keep low in dialysis patients and those with advanced CKD,” she told Medical News Today.

Plant-derived omega-3s, such as alpha-linolenic acid (ALA), which is found mainly in nuts and seeds, had no effect on CKD risk.

Corresponding author, Dr. Kwok Leung Ong, senior research fellow at the School of Biomedical Sciences, University of New South Wales (UNSW), Australia, told MNT:

“For plant-derived ALA, the finding was not too surprising although still interesting to observe, since ALA generally shows weaker effect on metabolic risk factors such as lipid, glucose and inflammatory markers in clinical trials, when compared to EPA and DHA.”

“The important implication from our study is that adequate consumption of seafood and oily fish (where most such blood omega-3 fatty acids come from) may help to prevent or delay the development of chronic kidney disease.”

— Dr. Kwok Leung Ong

And Dr. Laird agreed: “The seafood-derived omega-3 is in a ‘ready to use’ form by the body already, and it makes scientific sense it would be associated with a health outcome such as CKD.”

Although the findings from the study are promising, the results do not indicate a causal relationship.

“It should be noted that our findings do not prove a causal relationship between seafood n-3 PUFA and CKD risk as the findings were observational, but they are supportive and consistent with current clinical guidelines that recommend adequate intake of seafood as part of healthy dietary patterns, especially when seafood replaces the intake of less healthy foods,” Dr. Ong said.

Dr. Laird, meanwhile, called the findings “controversial,” and said many other compounds could have had a similar effect.

“[T]he authors did not take into account other dietary factors (including other vitamins (e.g., vitamin D) and minerals found in fish) which also have anti-inflammatory benefits which the EPA and DHA levels are just tracking against,” he noted.

“Direct mechanisms could have included anti-inflammatory, direct effects on the immune system and dampening ‘inflamaging’. In addition, higher DHA and EPA may have reno-protective properties in kidney diseases, with attenuation of fibrosis.”

— Dr. Eamon Laird

“An earlier analysis of trials in 2017 found that there was no reduction in markers of inflammation (CRP, IL-6, TNF-alpha) in patients with CVD supplemented with omega-3. However, the effects could be localized to the kidney and not show up in body system-wide inflammatory measures,” Dr. Laird added.

The Dietary Guidelines for Americans recommend that adults eat 8-10 ounces (225-280g), or 2-3 portions, of seafood each week. Children should eat 2-3 ounces weekly to limit methylmercury exposure. The American Heart Association advises a similar intake. On average, Americans eat less than half of that.

Most seafood contains some n-3 PUFAs, but the highest levels are found in cold-water oily fish such as:

  • salmon
  • anchovies
  • herring
  • mackerel (Atlantic and Pacific)
  • tuna (bluefin and albacore)
  • sardines

People can also get their seafood-derived omega-3s from fish oil supplements. For people on a vegetarian diet, chia seeds, flax seeds, and walnuts are high in ALA, some of which the body converts to EPA and DHA.

DHA and EPA are both thought to reduce inflammation, which has been linked to a range of chronic conditions, such as type 2 diabetes, heart disease, and other autoimmune disorders.

So, although this study does not prove conclusively that including seafood in your diet will reduce your risk of CKD, for most people, increasing the intake of seafood, particularly oily fish, is likely to benefit overall health.

  • Researchers followed 67,688 individuals over an average period of 25 years to better understand the link between symptoms of dementia and psychological distress (stress, depressive mood, exhaustion, and nervousness).
  • The researchers found that psychological distress symptoms are associated with an increased risk of dementia.
  • A better understanding of dementia risk factors may pave the way for dementia prevention.

According to the World Health Organization, there are currently 55 million people worldwide living with dementia, with nearly 10 million new cases being diagnosed each year. To lower the risk of dementia in a population, researchers must understand what causes dementia.

Several studies have looked at the association between psychological distress—an umbrella term that encompasses symptoms of anxiety, depression, and stress—and dementia. However, the link between the two remains unclear.

Now, a new study published in JAMA Network Openexplores this link between psychological distress and dementia.

The study was conducted by researchers from the Finnish Institute for Health and Welfare, the University of Helsinki, and the University of Eastern Finland.

Previous studies, such as one published in 2022, concluded that individuals with depression levels that were increasingly severe, chronically high, or chronically low had a higher likelihood of developing dementia compared to individuals without depression or with decreasing depression symptoms.

Other studies have found that anxiety, vital exhaustion, and psychological stress are associated with a later onset of dementia.

On the other hand, a 28-year follow-up study on the relationship between depression and dementia found that depression was mostly caused by dementia rather than dementia being caused by depression.

Since psychological distress is common in the early stages of dementia, risk-determining studies must have a sufficiently long gap between the measurement of psychological distress and the incidence of dementia for the result to be considered reliable.

Studies with an elderly population and short follow-up periods fail to separate the early (prodromal) symptoms of dementia from causal risk factors.

Another factor to keep in mind in studies on psychological distress and dementia is the competing risk of death. According to some authors, studies should take into account whether people with mental health problems tend to die at younger ages and thus may not live long enough to show dementia.

“We could clarify that connection using one of the largest population data sets, long follow-up, and careful modeling of death [from] other causes,” Dr. Sonja Sulkava, principal investigator for the study and postdoctoral researcher in Professor Tiina Paunio’s group, told Medical News Today.

The study included 67,688 individuals, ages 25–74, who participated in the National FINRISK Study surveys between 1972 and 2007.

FINRISK was a large Finnish population study on risk factors in chronic, noncommunicable diseases that was carried out for 40 years, and its surveys included questions on symptoms of psychological distress.

Dementia and mortality data for each participant until December 31, 2017, was obtained from the Finnish Health Register.

“Dr. Sulkava’s report adds to the new evidence that people who have mental health problems in early life tend to develop dementia in later life. This opens a promising window for dementia prevention.”

Taking into account the competing risk of death and other factors that affect the risk of dementia, the researchers found that symptoms of psychological distress were associated with a 17-24{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increased risk of dementia in an etiological Poisson model and with an 8-12{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} increase in the incidence of dementia in the Fine-Gray model.

“Our study suggests that symptoms of psychological distress, e.g., exhaustion, depressive mood, and experience of stress, are risk factors for dementia, and not only prodromal symptoms of underlying dementia disorder. [However], [w]e cannot prove causality.”
— Dr. Sonja Sulkava

Dr. Moffitt expressed confidence in the findings of this study, noting that the results converge with those of a New Zealand population study.

“In 2022, my team also reported that mental health is an early factor in later dementia. We followed 1.7 million New Zealanders for 30 years in national medical records and found that early-life mental disorder predicted 4 times greater risk of later-life dementia,” he said,

Like the Finland population study, the New Zealand study also controlled for the competing risk of death.

Dr. Linda Ernstsen, associate professor at the Norwegian University of Science and Technology, who was not involved in the study, told MNT:

“The take-home message from this study is that mental health issues and feeling of distress are associated with premature death and dementia. These findings illustrate the need to focus on mental health at all ages and to identify causes and triggers.”

In their paper, the researchers note that individuals who did not participate in the FINRISK survey or had missing information also had more risk factors and increased risk of dementia and mortality, and this selective participation and non-responsiveness may skew the study results.

The researchers also acknowledged that their measurement of psychological distress was not based on a validated multi-item questionnaire but on several single-item measures for different symptoms of psychological distress. However, these measures correlate significantly and show a consistent pattern of association with dementia.

Moreover, the researchers acknowledged that there was no available information about traumatic brain injury, hearing impairment, and low social contact—three established risk factors for dementia.

Dr. Sulkava added that study participants were asked to report their current symptoms of psychological distress only once, and this leads to a lack of “longitudinal perspective” for the symptoms.

Dr. Ernstsen pointed out that information about social isolation or marital status was not included. Research has found that being married protects against dementia.

“We also know that cardiovascular disease is associated with both mental health and dementia risk, but it was only the presence of diabetes that was adjusted for in the present study,” Dr. Ernstsen added.

Dr. Archana Singh-Manoux, research professor and director at the French Institute of Health and Medical Research (INSERM), who was not involved in the study, told MNT that the major limitation of this study relates to reverse causation.

In one of the models used to calculate dementia risk, when the researchers excluded individuals with a follow-up of fewer than 10 years, the sensitivity analyses showed no significant associations between psychological distress and dementia.

“These findings suggest that the main results of the paper are due to dementia events occurring soon after the measure of psychological distress. This is a perfect demonstration of reverse causation, i.e., psychological distress in the preclinical phase of dementia rather than psychological distress ‘causing’ dementia.”
— Dr. Archana Singh-Manoux

When asked about the next research steps, Dr. Sulkava told MNT that larger studies and longer follow-ups will be needed.

“Stress, exhaustion, and depressive symptoms are tightly linked to sleep problems, which are suggested to be risk factors for dementia too. However, most epidemiological studies lack large enough sample[s] or long follow-up,” she said.

“Our next step is to study sleep problems and sleep length and dementia risk using the large Finnish cohorts,” she added.

  • A new analysis of information from a significant, nationally consultant team of more mature Individuals finds an association concerning currently being socially isolated and producing dementia.
  • Individuals at possibility are these who only occasionally have get hold of with other individuals and have handful of energetic associations.
  • The study’s getting implies that by remaining or starting to be more socially energetic, 1 might lower the risk of dementia.

A new study has investigated regardless of whether social isolation can have an effect on the growth of dementia in more mature people today.

The new evaluation indicated that socially isolated adults had been 28{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} far more very likely to acquire dementia in excess of a period of time of nine decades, no matter of race or ethnicity, when compared to people who weren’t socially isolated.

The research is an evaluation of facts from 5,022 more mature U.S. grown ups who took aspect in the longitudinal Nationwide Well being and Aging Traits Study (NHATS). Of the NHATS review cohort, 1,172 individuals, or 23.3{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}, were being classified as socially isolated — 3,850 (76.7{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}) were not.

Further than its association with dementia, social isolation has also been connected to bad mental wellness and emotional effectively-staying in older individuals.

The research is posted in the Journal of the American Geriatrics Culture.

Although there is no common comprehending of what “social isolation” usually means, the study bases its use of the term on the definition presented in a report from the Countrywide Academies of Sciences, Engineering, and Drugs, which suggests:

“Social isolation is defined as the goal condition of owning couple social interactions or infrequent social get in touch with with many others.”

The new study lists numerous attributes that qualify a person as currently being socially isolated: dwelling alone, possessing no one or only just one particular person with whom they can focus on essential issues, and obtaining minimal or no engagement in social or religious teams.

The persons who experienced as socially isolated in the research satisfied two or a lot more of the next conditions:

  • Lived alone.
  • They did not have two or a lot more folks in the final yr with whom they could examine important issues.
  • They did not attend religious providers in the past month.
  • Did not do take part in other activities, this sort of as volunteer do the job, golf equipment, conferences, or teams, in the last month.

The authors of the analyze point out to Health-related Information Now the significance that upcoming exploration investigates social isolation and dementia in a more in-depth method. These types of study may glance into the outcome every single particular person criterion could have on dementia.

They also visualize long run experiments that take into consideration achievable discrepancies in the way social isolation might occur and influence unique race and ethnicity teams.

Dr. Rosanne Freak-Poli, senior research fellow at Monash University’s Drugs Monash Wellbeing, who was not included in the study, pointed out that “[s]ome men and women might confuse social isolation with social help.”

Social help, she stated, is about how social contacts are used. For illustration, a individual might experience sufficient assist from a several good good friends who satisfy their social demands.

“I like to describe men and women as ‘enjoying their solitude’ if they are socially isolated but also feel socially supported,” she informed MNT.

NHATS surveyed persons residing in communities and did not contain older people today institutionalized in nursing houses or household care.

“However, persons in nursing homes or residential treatment normally report emotion lonely or acquiring minimal social assistance. Loneliness and minimal social guidance are also risk factors for ill health and fitness and decrease very well-being,” stated Dr. Freak-Poli.

In the meantime, Dr. Angelina R. Sutin, professor at Florida State University’s College or university of Medicine, who was not involved in the present research, stated she was “not conscious of any scientific tests that have examined no matter if social wellness in residential configurations is involved with dementia danger.”

She famous that most present study focuses on men and women in these kinds of options who already have dementia.

The study’s corresponding creator, Dr. Thomas K. M. Cudjoe, assistant professor of medicine at Johns Hopkins Medication in Baltimore, Maryland, explained three means in which social isolation could direct to dementia.

1st, he cited a strong association amongst social isolation and actual physical and mental health chance aspects for dementia, this sort of as hypertension, coronary heart sickness, and melancholy. As social isolation encourages these disorders, it may well increase the threat of dementia.

Dr. Cudjoe also mentioned that a lack of social engagement could direct to a reduction in cognitive activity and, for that reason a lessen cognitive reserve.

“The cognitive reserve speculation indicates people today with reduce ranges of cognitive operating and reserve are a lot more vulnerable to the pathology involved with dementia.”
— Dr. Thomas K. M. Cudjoe

Last but not least, Dr. Cudjoe proposed that socially isolated folks may well lack added benefits affiliated with larger social connectedness, which includes social help, data-sharing, coordination of healthcare providers, and access to those companies.

“Social isolation matters for cognitive wellbeing. Clinicians must be contemplating about and assessing the existence or absence of social connections in their clients,” stated Dr. Cudjoe.

Dr. Cudjoe said the study’s nationally representative team of contributors strengthens its conclusions, enabling them to be generalized across U.S. populations.

“This is critical in our pondering of wide-primarily based methods or coverage,” he mentioned.

More mature older people may perhaps take into account achieving out more to other persons, possibly on an personal basis or by participating in actions with teams of persons, to decreased the chance of acquiring dementia.

“Getting out of your household and interacting with persons at minimum as soon as for every month can have large positive aspects to your long term well being and rapid perfectly-staying.”
— Dr. Rosanne Freak-Poli

“When I imagine about the other wellbeing behaviors, these as healthy taking in or bodily exercise, they feel a lot more tricky to obtain for the same well being reward,” added Dr. Freak-Poli.

Dr. Sutin underscored the study’s upside:

“The fantastic information is that social isolation is modifiable, and could be a focus on of intervention that may possibly assistance reduce the hazard of dementia involved with it.”
