New York, While aerobic exercise generally benefits health, extreme endurance exercise -- like marathon and triathlon -- can raise a person's risk for sudden cardiac arrest and atrial fribrillation, according to a new study.
After reviewing more than 300 scientific studies, the research team found that physically active people, such as regular walkers, have up to a 50 per cent lower risk of heart attack and sudden cardiac death.
However, the team also identified potential risks with intense exercise training, according to the study published in the journal Circulation.
"Exercise is medicine, and there is no question that moderate to vigorous physical activity is beneficial to overall cardiovascular health. However, like medicine, it is possible to underdose and overdose on exercise -- more is not always better and can lead to cardiac events, particularly when performed by inactive, unfit individuals with known or undiagnosed heart disease," said Barry A Franklin, Professor at Oakland University in the US.
"More people are running marathons, participating in triathlons and doing high-intensity interval training. The purpose of this statement is to put the benefits and risks of these vigorous exercise programmes in perspective," Franklin added.
The research group also reviewed a small study that concluded that the risk of sudden cardiac death or heart attack is low among people participating in high-intensity exercise such as marathons and triathlons.
However, over time, the risk of heart attack or sudden cardiac death among male marathon participants has risen, suggesting that these events are attracting higher risk participants (those who may have an underlying or undiagnosed cardiovascular condition such as heart rhythm abnormalities or a prior heart attack).
For women, who comprised only 15 per cent of the study's population, the occurrence of sudden cardiac death was 3.5 fold less than in men.
Among participants in triathlons, almost 40 per cent of cardiac events occurred in first-time participants, indicating that inadequate training or underlying heart problems may be involved.
The research team also found that half of cardiac events occur in the last mile of a marathon or half-marathon, so maintaining a steady pace rather than sprinting is advised.
The risk of cardiac events is greater at high altitudes, but can be decreased by spending at least one day acclimating to the elevation prior to strenuous activity, the study said.
For people who want to become more active, the researchers suggested that most people can start a light programme of exercise and build up slowly to a moderate to vigorous exercise regimen.(IANS)
New York, Consuming sugary drinks may be linked to lipid imbalance, which increases the risk of cardiovascular diseases (CVDs), according to a new study.
The study, published in Journal of the American Heart Association, said consuming 12 ounces of sugary drinks more than once a day was linked to lower high-density lipoprotein cholesterol (HDL-C) and higher triglycerides in the middle-aged and older people. Both of this reportedly raises CVDs risks.
Previous studies had linked added sugar to increase in CVDs risks.
"The research reinforces our understanding of potential negative impact of sugary drinks on blood cholesterol, which increases heart disease risks," said study researcher Eduardo Sanchez from the American Heart Association in the US.
It's one more reason for us to cut back on soda and other sugar-sweetened beverages, Sanchez added.
According to researchers, dyslipidemia could be one pathway by which sugary drinks may increase CVDs risks.
To determine the impact of sugary drinks on triglyceride and cholesterol levels, researchers studied observational medical data of 5,924 people from the Offspring and Generation 3 cohorts of the Framingham Heart Study, who were followed for 12.5 years between 1991 and 2014.
For this study, the beverages were defined as 12 ounces of sugary drinks, like soda, fruit-flavoured drinks, sports drinks, pre-sweetened coffee and tea; 12 ounces of low-calorie sweetened beverages, including naturally and artificially sweetened 'diet' soda or other flavoured drinks; or 8 ounces of 100 per cent fruit juices with no added sugar.
Researchers analysed how the different drinks and their consumption correlated with changes in cholesterol and triglyceride levels over four years.
They found consuming sugar-sweetened beverages (more than 12 ounces a day) was linked with 53 per cent higher incidence of high triglycerides and 98 per cent higher incidence of low HDL cholesterol (the good cholesterol) compared with those who consumed less than one serving a month.
Drinking low-calorie sweetened beverages didn't appear to be associated with increased dyslipidemia risk among people who regularly consumed low-calorie sweetened beverages.
According to the study, consuming up to 12 ounces of 100 per cent fruit juice a day was not associated with adverse changes in cholesterol or dyslipidemia, though further research is needed to warrant this finding.
"Reducing or eliminating sugary drink consumption may be one strategy that could help people keep their triglyceride and HDL cholesterol at healthier levels," said lead study author Nicola McKeown from Tufts University in the US.
Around 40-50 per cent US adults suffer from dyslipidemia, an imbalance of cholesterol and triglyceride in blood, which increases the risk of CVDs. (IANS)

A hostile workplace environment wherein dysfunction and drama reign, whether its the result of a narcissistic boss, vindictive coworkers, absence of discipline, outflow of excessive bad news highly cost some employees who pay for immense caring.
In addition, the environment which is harming the morale of the employees, this kind of climate for caretaker in careers creates a different kind of stress leading to "compassion fatigue", also called "vicarious traumatization".
It is a term bandied about as secondary disorder which is the emotional residue or strain of exposure to working with those suffering from the consequences of traumatic events. Thus more empathetic and open to others' burnouts and pain the workers are, the more likely they will share those victims' feelings of heartbreak and devastation".
Compassion fatigue is more likely to affect professionals with less experience and people who willingly help others in short-term spurts. These armature employees may have less coping mechanisms and debriefing opportunities as those who repeatedly work with traumatized people in hostile work environments, Dr Paras Life-leadership Coach and Founder of Matrrix.
Also, due to the extensive social media coverage of human suffering and worldwide disasters, more people are beginning to report symptoms that mirror those of compassion fatigue which is taking a huge toll in their career and personal lives.
Essentially, compassion fatigue can occur due to indirect exposure on one case or due to a cumulative level of trauma. It is a quick-onset engrossed like a great rock inside your head which is immovable with the midst of emotional exhaustion, confusion, callousness, anxiety and loneliness caused due to feelings of inequity toward the therapeutic or caregiver relationship. The gradual lessening of compassion can easily weigh down your self-esteem and unable to nurture their inner-self, Dr Paras explains.
Burnout vs Compassion Fatigue
Untreated or unmanaged compassion fatigue can result in burnouts, but there's a significant overlap between compassion fatigue and burnouts. Burnouts are related to the job environments wherein compassion fatigue are normal displays of chronic stress resulting from showing empathy towards the employees who are suffering or getting upset about the constant rolling bad news in media or treatments in toxic workplace.
Compassion fatigue can lead to anxiety, numbing towards tragedy and even depression. You must navigate these symptoms within you.
Difficult separating work life from traumatized events or a person at workplace
Preoccupation with trauma
Withdrawing from work or compassion
Isolation and loneliness
Loss of purpose in life
Impaired immune system
Bottled-up emotions within due to loss of morales
Loss of Self-worth due to hopelessness
Inevitable numbness, chillness and panic disorders
Compassion has been increasing among millennial and professionals in today's generation and those at risk needs to be encouraged to make them more resilient. Individuals suffering from compassion fatigue will often wander off and adopt the tendency of escapism (escape from reality) for the absorption of peace and relief. Compassion fatigue can cause the sense of impending doom or danger. It can also cause tumbling and shaking.
To-do's to handle compassion fatigue at workplace:
All we need to do is close a couple of tabs in our brain and handle the situation very precisely.
Balance your empathy - Mostly, people who are a natural empath go as far as feeling the depths of the world's problems-they see the hurt, pain, and confusion caused by war, greed, and injustice happening in the workplace or social environment, and they feel all of it, too. This can lead to compassion fatigue your state of emotions are unbalanced and it becomes challenging to cope up. It's highly imperative to understand how to make empathy work for you so you don't become a victim to other people's emotions and thought processes.
An ideal way to balance your empathy is to - Put yourself first! This can go against the grain of anyone who is victimized. However, as the proverb says - "One cannot pour from an empty cup." so make sure your cup is filled all the time. As making sure your needs are taken care of, you will be able to better take care of other people. Set boundaries and be selective in your response to avoid becoming prone to get caught up in other people's stories and then riding the rollercoaster of emotions and focus on yourself.
Discover version of yourself - Becoming the best version of yourself means getting back to your quintessential self. Finding a great hobby or taking a sabbatical break from your job doesn't have to be a blemish. It's a nail down strategy for self-improvement; you must propel yourself to uncover the essentials within you. "You-ness"- the values, interests and passions that define who you are in life and the world.
Once you understand yourself, you're able to define a clear vision of your best self and map out your route to get there.
Reduce Those Tech Carving - Social media is always noisy; even though the sound won't hurt your ears, it will definitely hurt your mind with an exposure to constant bad news. Cutting down on social media and building a strong and supportive team around you that you can debrief with both personally and professionally.
Self-care is very important if you don't want to deal with big emotional tolls all the way coming from other people. It is recommended that people reduce the tech and try to meditate, pray, practice mindfulness or yoga. Walking in nature, reading spiritual texts, listening to music or taking up a hobby that helps fuel the inner self are also really good ways to help cope with carrying emotional weight.

New York, Researchers have found that even relatively moderate amounts of dairy milk consumption can increase women's risk of breast cancer -- up to 80 per cent depending on the amount consumed.
"Fairly strong evidence that either dairy milk or some other factor closely related to drinking dairy milk is a cause of breast cancer in women," said study first author Gary E. Fraser from Loma Linda University in the US.
"Consuming as little as 1/4 to 1/3 cup of dairy milk per day was associated with an increased risk of breast cancer of 30 per cent," Fraser said.
By drinking up to one cup per day, the associated risk went up to 50 per cent, and for those drinking two to three cups per day, the risk increased further to 70 per cent to 80 per cent, the researchers said.
For the findings, published in the International Journal of Epidemiology, dietary intakes of nearly 53,000 North American women were evaluated for the study, all of whom were initially free of cancer and were followed for nearly eight years.
Dietary intakes were estimated from food frequency questionnaires (FFQ), also repeated 24 hour recalls, and a baseline questionnaire had questions about demographics, family history of breast cancer, physical activity, alcohol consumption, hormonal and other medication use, breast cancer screening, and reproductive and gynecological history.
By the end of the study period, there were 1,057 new breast cancer cases during follow-up. No clear associations were found between soy products and breast cancer, independent of dairy.
But, when compared to low or no milk consumption, higher intakes of dairy calories and dairy milk were associated with greater risk of breast cancer, independent of soy intake, the study said.
The researchers noted that the results had minimal variation when comparing intake of full fat versus reduced or nonfat milks; there were no important associations noted with cheese and yogurt.
"However," he said, "dairy foods, especially milk, were associated with increased risk, and the data predicted a marked reduction in risk associated with substituting soymilk for dairy milk."
According to the researchers, possible reasons for these associations between breast cancer and dairy milk may be the sex hormone content of dairy milk, as the cows are of course lactating, and often about 75 per cent of the dairy herd is pregnant. Breast cancer in women is a hormone-responsive cancer.
Further, intake of dairy and other animal proteins in some reports is also associated with higher blood levels of a hormone, insulin-like growth factor-1 (IGF-1), which is thought to promote certain cancers.
"Dairy milk does have some positive nutritional qualities, but these need to be balanced against other possible, less helpful effects," Fraser concluded. (IANS)

London. Researchers have revealed how a simple blood test could be used to help identify cardiovascular ageing and the risk of heart disease.
The study, published in the Journal of the American College of Cardiology, reported that higher levels of amyloid-beta in the blood may be a key indicator of cardiovascular disease.
Amyloid-beta is known to be involved in the development of Alzheimer's disease, yet researchers have now concluded that it may have a key role to play in vascular stiffening, thickening of the arteries, heart failure and heart disease progression.
It is hoped that this research will one day lead to the development of a simple blood test that could be used as a clinical biomarker to identify patients who are most at risk, so that preventative measures can be put in place and death rates reduced.
"Our work has created and put all the pieces of the puzzle together. For the first time, we have provided evidence of the involvement of amyloid-beta in early and later stages of cardiovascular disease," said study researcher Konstantinos Stellos from Newcastle University in the UK.
For the findings, the research team analysed blood samples from more than 6,600 patients from multiple cohort studies in nine countries, and found that patients could be divided into high and low risk categories of heart disease based on their amyloid-beta levels.
"What is really exciting is that we were able to reproduce these unexpected, clinically meaningful findings in patients from around the world. In all cases, we observed that amyloid-beta is a biomarker of cardiovascular ageing and of cardiovascular disease prognosis," Stellos added.
The study proposed the existence of a common link between both conditions, which has not been acknowledged before, and could lead to better patient care.
The findings suggest that the higher the level of amyloid-beta in the blood the higher the risk of developing serious heart complications.
In the future, it is hoped that a simple blood test could be added to the current method of patient screening, known as the GRACE score, which assesses heart attack risk and guides patients' treatment plans.
Using the GRACE score, eight factors are used to predict the risk of heart attack, including age, blood pressure, kidney function and elevated biomarkers. (Agency)
New York, Feb 25. Researchers have found that children who have been abused, mistreated or neglected at home are more likely to start smoking cigarettes and other substances.
The study, published in the journal Substance Use & Misuse, showed that physical abuse of children in high-risk homes, especially when they're toddlers or teens, dramatically increases the odds that their adolescent experimentation with cigarettes will lead to a heavy smoking habit.
For the findings, the study examined data on children who were at high risk for abuse and neglect -- either because they had been referred to a child protective service or lived in conditions associated with the likelihood of maltreatment or both.
"I wanted to look at different types of maltreatment and whether they have an impact on cigarette smoking," said study lead author Susan Yoon, Assistant Professor at Ohio State University in the US.
"Adolescent cigarette smoking is a really serious social problem and public health concern. Brain development is not complete until late adolescence or during young adulthood, and cigarette smoking is associated with damage in brain development," Yoon said.
"We also know that those who start smoking cigarettes during adolescence are more likely to continue smoking into adulthood," Yoon added.
For the results, the research team used data on 903 adolescents, who were assessed at age 12, 16 and 18.
A breakdown of different types of abuse and neglect experienced by the sample population during three different time periods (early childhood, school age and adolescence) confirmed how vulnerable these kids were.
The researchers used their responses about smoking between the ages of 12 and 18 to identify three patterns of cigarette use: stable low/no use (61 per cent of respondents), gradually increasing use (30 per cent) and sharply increasing cigarette use (nine per cent).
"It was almost shocking how the pattern of cigarette use over time went up so drastically in the sharply increasing use class," Yoon said.
"They were pretty similar to the others at age 12 -- almost 80 percent didn't smoke. At age 16, we saw that almost 60 per cent had used cigarettes more than 20 days in the past year and by 18, every single kid in this group reported heavy use of cigarettes," Yoon added.
A statistical analysis showed that adolescents who experienced early childhood physical abuse were 2.3 times more likely to be in the sharply increasing cigarette use group compared with the stable no/low group.
Physical abuse during adolescence had an even stronger effect -- this type of mistreatment at that point in life was linked to 3.7 times higher odds for sharply increased cigarette use.
Adolescents who had been neglected during early childhood were 1.89 times more likely to be in the gradually increasing cigarette use group than in the stable no/low use group.
About 40 per cent of these smokers had reported using cigarettes at age 16, and by age 18, more than 80 per cent were smokers, and about 40 per cent had smoked on more than 20 days in the previous year, the study said. (Agency)
