Teenagers Facing Loneliness more than elders

It is believed that elderly people are mostly victims of loneliness. But in one research, it has been found that teenagers feel most lonely themselves.

In a survey conducted in Britain, 40 percent of people aged 16 to 24 said they often feel lonely. At the same time, only 29 percent of the 65-74 people said they felt lonely.

The University of Manchester and Brunel University London did this survey across the country. It included more than 55 thousand people aged 16 years and above. He was asked about his experiences about loneliness. Some experts say that youth feel more lonely because they are in the age of finding themselves.

Live online active

16 to 24 years old people are looking for their new identity. During this time they learn to control emotions. Sothey become alone.

This research also revealed that those who were feeling lonely themselves were very active in social media and online and had many virtual friends in their world. That is, they can not be physically received, but they know each other in the world of the Internet.

Removing Ovary May Increase The Risk of Chronic Kidney Disease

Many women with a history of cancer in the ovaries undergo preventive surgeries, A Mayo Clinic study found that there is a high risk of kidney disease associated with this procedure.

A study conducted by Mayo Clinic, Rochester (USA) researchers published this month in the Clinical Journal of the American Society of Nephrology showed that surgical removal of the ovaries increases the risk of women developing chronic kidney failure.

“This is the first study to show an important link between estrogen suppression in younger women and kidney damage Women who have surgery to remove the ovaries have an increased risk of developing long-term chronic kidney failure term, “Walter Rocca, a neurologist, epidemiologist and lead author of the study, said in a statement.

Previous work had already indicated that estrogen, the female hormone, has a protective effect on the kidneys. But it was not clear until now if the removal of ovaries in women approaching menopause had some direct effect on kidney function.

Rocca and her group studied the medical records of 1,653 women who live in Olmsted County, Minnesota, whose ovaries had been removed before the age of 50 with an equal number of women of the same age who did not undergo surgery. surgery.

The Mayo Clinic researchers found that women whose ovaries had been removed had a 6.6 percent higher risk of developing chronic kidney failure, compared to those who did not have surgery. The risk of renal failure was even higher in women under 46 years of age. Women whose ovaries had been removed before age 46 had an increase of 7.5 percent in the risk of developing chronic renal failure.

An estimated 30 million adults in the United States suffer from chronic kidney failure and, according to the Centers for Disease Control and Prevention, is the ninth leading cause of death in the United States.

As indicated in the statement Rocca, “these results emphasize the need for doctors to talk about the increase in the potential risk of developing chronic kidney failure with women who are considering the removal of ovaries.”

“In women who do not present a genetic risk of developing breast or ovarian cancer, we recommend not using the removal of the ovaries as a preventive option since it entails an increased risk of various diseases, including chronic renal failure, and an increased risk of death, “added Rocca.

One of the best known cases about this problem was faced by actress Angelina Jolie who in 2015 underwent surgery to remove ovaries and fallopian tubes to reduce the possibility of cancer, a disease that killed her mother, her grandmother and his aunt.

Superfood are Necessary for Health says American Heart Association

Food that is mostly plant-based are considered as superfood. But fish and dairy are also considered as superfood. Superfoods are nutritionally dense and hence are good for health. Foods like Blueberries, salmon, kale and acai are just a few examples of foods that have garnered the “superfood” label.

There is no criteria to determine the superfood but according to the American Heart Association (AHA).

“Superfoods don’t have their own food group, as a dietician, I think ‘superfood’ is more of a marketing term for foods that have health benefits” said Despina Hyde, a registered dietician with the weight management program at New York University’s Langone Medical Center.

Consumption of food that is filled with nutrients like superfood is usually a good idea, Hyde mention to live science. And the key to healthy diet is consuming the variety of nutrients foods in right quantity, Hyde added.

Here is some more information about the superfood other than the normal ones.

Quinoa is consumed by many especially by the vegetarians. Quinoa is considered to be high and rich in proteins. It is one amongst the best only plant based food that is provides all the essential amino acids. This amino acid can also be obtained by combining lentils with rice or even beans and toast.

Coconut oil has exaggerated in quality, because of claims that it will speed up metabolism and scale back weight and sterol. However analysis suggests these claims area unit idle. It’s high in saturated fat, that the NHS and British Heart Foundation advocate we have a tendency to scale back.

It’s conjointly low in monounsaturated fat which helps lower sterol and probably scale back risk of cardiopathy. Swap vegetable oil for oil that contains considerably additional monounsaturated fat and far less saturated fat than vegetable oil.

Gadgets and Digital Screens Are Harming Children’s Mental Ability

Children between eight and eleven who use digital screen gadgets for less than two hours a day performed better on mental ability tests, according to a study published in The Lancet (Child and Adolescent Health).

The study included approximately 4,500 children in the United States aged 8 to 11 years and measured their habits compared to the Canadian Guide for 24 hours of children and youth.

He found that 51% of children received the recommended nine to 11 hours of uninterrupted sleep per night, 37% met the recreational screen time limit of two hours or less per day, while 18% met the recommendation of physical activity of at least 60 minutes of accumulated physical activity per day.

The limitation of recreational screen time of children less than two hours a day, together with sufficient sleep and physical activity is associated with better cognition.

The researchers concluded that more work is now needed to better understand the effects of different types of screen use in children under the age of 11, and recognize that their observational study shows only an association between screen time and cognition and not You can prove a causal link. (See also: The blue light of the screens would cause long-term blindness)

The study questioned the 4,500 children about physical activity, sleep, recreational use of the screens. They also completed tests of language, memory and attention, and the scientists divided the population sample between household income, education of their parents and that of children, ethnicity, body mass index, hormonal development and brain traumas.

According to the BBC, children who had less than two hours of recreational screen time every day slept nine to 11 hours and performed at least one hour of physical activity better than those who did not.

Less than two hours of screen time per day was the factor most related to better performance in the test.

Dr. Jeremy Walsh of the CHEO Research Institute in Ottawa, Canada, told the media: “Based on our findings, pediatricians, parents, educators and politicians should promote the limitation of recreational screen time and prioritize healthy routines. of sleep during childhood and adolescence “.

The study took data from the adolescent brain cognitive development study sponsored by the National Institutes of Health and included surveys by parents on how many hours of sleep a child had, how often they were physically active, and how much time they had. screen they had.

Walsh believes that 30% of participants who did not comply with any of the guidelines are the ones who have more to gain from adjusting daily behaviors.

“They can benefit more because they are not receiving any of the benefits derived from complying with these guidelines,” Walsh told CNN.

Immunotherapy to Treat Breast Cancer

Customized precision medicine has taken the lead in oncological research and scientists are striving to improve in each patient, individually, mechanism and the route to aim for the most appropriate therapeutic target. Targeted therapies begin to multiply and a group of researchers from the Vall d’Hebron Institute of Oncology (VHIO) has presented an advance in this area, an immunotherapy that directs the immune system towards tumor cells in certain types of breast cancer.

This research began more than 10 years ago, when the VHIO scientists found a protein present in a subtype of breast tumors, the HER2 +. It is the p95HER2 protein, a component found on the surface of tumor cells, but never in healthy cells. “We thought that this component could be used to direct the immune system towards the tumor cells ,” recalls Dr. Joaquim Arribas, director of the VHIO Preclinical Research Program. And so it has been.

Scientists have designed an immunotherapy that involves the injection of an antibody that functions as a kind of magnet: the bispecific T-lymphocyte antibodies, whose structure has two arms, so that with one of them has the ability to target a certain protein and stick to it, while, with the other, it binds to the cells of the immune system.

In this case, the antibody used uses one of its binding sites to bind to the protein p95HER2 and with the other it attracts the T lymphocytes of the immune system to the tumor cells where this protein is present. The antibody guides the immune system to those malignant cells to destroy them without damaging healthy tissue. “It’s a way to create a physical bridge between the immune system and the tumor cells,” says Arribas.

Researchers have successfully tested this treatment in animal tissues, but Arribas notes that “they are not remote models of patients with tumors.” In fact, to develop the experiment, the scientists took samples of tumors from real patients and their blood to reproduce, in the laboratory, the immune system of these patients. The VHIO team has published this finding in the journal Science Translational Medicine .

Although they have only tried it, for now, in preclinical studies, the good results predict a clinical trial with patients in one or two years, explains Arribas. This treatment is designed for patients with a breast tumor of the mentioned subtype and who have not responded to other therapies. HER2 + breast cancer has effective treatments in 70% of cases, but the other 30% of patients are left without therapeutic alternatives.

Immunotherapy has shown positive effects in patients with metastases when all other available therapies fail. However, stimulating the defenses of the human body can have unexpected side effects, such as the immune system attacking healthy cells and causing autoimmune diseases.

But this new therapy, in that it redirects the immune system only to malignant cells, can expand the therapeutic arsenal also in other types of cancer. Arribas states that “there is evidence that it can work in 15% of stomach tumors.” The researchers add that, since this mechanism is directed at home against tumor cells, without damaging healthy tissue, it could also be used for chemotherapies that already exist and are not used because of their high toxicity.
