Parents better keep their children away from television sets at an early age.
This developed after a recent study has shown that three-year-old children who are exposed to more TV appear to be at an increased risk for exhibiting aggressive behavior.
Based on the study, early childhood aggression can be problematic for parents, teachers and childhood peers and sometimes is predictive of more serious behavior problems to come, such as juvenile delinquency, adulthood violence and criminal behavior.
The researchers on their study has discovered various predictive factors for childhood aggression that include parents’ discipline style, neighborhood safety and media exposure.
The researchers revealed after music, television is the medium children aged 0 to 3 years are exposed to the most.
The researchers added although the American Academy of Pediatrics recommends no screen media for children younger than age 2, studies have found consistent use of television in that age group.
To get the result, Jennifer A. Manganello, Ph.D., M.P.H., of University at Albany, State University of New York, Rensselaer, and Catherine A. Taylor, Ph.D., M.S.W., M.P.H., of Tulane University School of Public Health and Tropical Medicine, New Orleans, analyzed data from 3,128 mothers of children born from 1998 to 2000 in 20 large U.S. cities to examine associations of child television exposure and household television use with aggressive behavior in children.
Watching television should be avoided by children to keep them away from aggressive behavior.
Parents were interviewed at the time of the child’s birth and at one and three years.
At three years, they were asked to report time the child spent watching TV directly as well as household TV use on a typical day. Aggression also was assessed at 3 years of age using a 15-item aggressive subscale for 2- and 3-year-old children. Demographic information and other risk factors for aggression were also noted.
About two-thirds (65 percent) of mothers reported that their 3-year-old child watched more than two hours of television per day. On average, children were exposed to an additional 5.2 hours of household TV use per day.
Direct child TV exposure and household TV use were both significantly associated with childhood aggression, after accounting for other factors such as parent, family, neighborhood and demographic characteristics. "One explanation that could link both child and household TV measures with aggression involves the parenting environment," the authors write. Households with higher rates of TV use may have fewer restrictions on children’s viewing habits such as exposure to unregulated television content. Increased household television use may also affect daily routines such as eating and communication patterns and may decrease time spent on other activities.
"Current American Academy of Pediatrics recommendations mainly suggest limitations for direct child exposure to TV and other media; however, our findings suggest that additional household TV use may also be an important predictor of negative childhood outcomes, such as
early childhood aggression," the authors conclude. "Future research in this area should consider inclusion of both of these TV variables along with additional parent-child interaction assessments, observational assessments when possible, quality and/or content of TV programs and longitudinal analyses."
Children with celiac disease could get relief from their bone problems with gluten-free diet
Author: admin
Parents who have children suffering from celiac disease could now smile a little bit despite the medical condition of their beloved angels.
Based on medical facts, a Celiac disease (CD) is an inherited intestinal disorder characterized by life-long intolerance to the ingestion of gluten, a protein found in wheat, rye, and barley. Although CD can be diagnosed at any age, it commonly occurs during early childhood (between 9 and 24 months). Reduced bone mineral density is often found in individuals with CD.
Metabolic bone disease remains a significant and common complication of CD. Reduced bone mineral density can lead to the inability to develop optimal bone mass in children and the loss of bone in adults, both of which increase the risk of osteoporosis. There also exists an additional risk of fracture in people with CD.
Those children suffering from celiac disease should engage in a gluten-free diet to be cured of their medical problem.
A recent medical study has shown that a gluten-free diet (GFD) promotes a rapid increase in bone mineral density that leads to complete recovery of bone
mineralization in children. A GFD improves, although rarely normalizes, bone mineral density in adults. Children may attain normal peak bone mass if the
diagnosis is made and treatment is given before puberty, thereby preventing osteoporosis in later life.
Also, nutritional supplements consisting of calcium and vitamin D seem to increase the bone mineral density of children and adolescents with CD.
"Our findings reinforce the importance of a strict gluten-free diet, which remains the only scientific proven treatment for celiac disease to date," the
researchers conclude. "Early diagnosis and therapy are critical in preventing celiac disease complications, like reduced bone mineral density", they added.
Those frequent users of acetaminophen, a known pail reliever should avoid getting hooked with the medicine.
A new study has shown that acetaminophen may be associated with an increased risk of asthma and wheezing in both children and adults exposed to the drug.
The data was taken from a recent study made by researchers from the University of British Columbia, Vancouver, BC, Canada, who conducted a systematic review and metaanalysis of 19 clinical studies (total subjects=425,140) that compared the risk of asthma or wheezing with acetaminophen exposure.
Based on the study, the pooled odds ratio (odds ratio for all studies combined) for asthma among users of acetaminophen was 1.63.
The risk of asthma in children who used acetaminophen in the year prior to asthma diagnosis or in the first year of life was elevated to 1.60 and 1.47, respectively.
Moreover, the study revealed a slight increase in the risk of asthma and wheezing with prenatal use of acetaminophen by mothers.
With the relevant data they gathered, the researchers speculate that acetaminophen’s lack of inhibition of cyclooxygenase, the key enzyme involved in the inflammatory response of asthma, may be one explanation for the potential link between acetaminophen use and asthma.
Are you a frequent user of amphetamine in your adolescence?
Well it is time for you to stop such addiction since too much intake of amphetamine could result in memory loss upon reaching adulthood.
The findings was taken on a study conducted by medical experts on a group of rats exposed to high doses of amphetamine.
Based on the study, the experts discovered that The declines in short-term or "working" memory are most pronounced when the rats are exposed during adolescence, rather than as adults.
"Animals that were given the amphetamine during the adolescent time period were worse at tasks requiring working memory than adult animals that were given the same amount of amphetamine as adults," said psychology professor Joshua Gulley, who led the study with graduate student Jessica Stanis. "This tells us that their working memory capacity has been significantly altered by that pre-exposure to amphetamine."
Gulley and his colleagues presented their findings at the annual meeting of the Society for Neuroscience in Chicago.
The researchers tested two types of amphetamine exposure: intermittent (a steady dose every other day) and "binge-escalation," in which increasing amounts of the drug were given over a period of four days, followed by a simulated binge a high dose every two hours for eight hours on the fifth day.
Too much intake of amphetamine should be avoided since it could lead to memory loss upon reaching adulthood.
The findings reveal some of the potential long-term consequences of amphetamine abuse by adolescents and also may be relevant to those taking amphetamines for therapeutic purposes, such as for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). Gulley cautions that the doses given to the rats are on the high end of what an older, larger adolescent might receive as a therapeutic dose, and that further study is needed to tease out the implications for human health.
The concerns are most robust for adolescents who abuse amphetamines, Gulley said, as they may use much higher doses than those who are prescribed drugs that contain amphetamines.
"Adolescence is a time when the brain is continuing to develop into its mature form, so drug exposure during this critical period could have long-lasting, negative consequences," he said. "Our findings reveal that adolescents are particularly sensitive to the adverse effects of amphetamine on cognitive function and that these effects can persist well after drug use is discontinued."
The researchers found that the types of shoes women wear, specifically high-heels, pumps and sandals, may cause future hind-foot (heel and ankle) pain. Nearly 64 percent of women who reported hind-foot pain regularly wore these types of shoes at some point in their life.
We found an increased risk of hind-foot pain among women who wore shoes, such as high-heels or pumps, that lack support and sound structure," says lead author Alyssa B. Dufour, a graduate student in the Institute’s Musculoskeletal Research Program.
Published in the October issue of the journal Arthritis Care & Research, the study is one of the first to examine the association between shoe wear beyond just high-heel use and foot pain. The researchers, who analyzed foot-examination data from more than 3,300 men and women in The Framingham Study, say past shoe wear among women is a key factor for hind-foot pain. They found no significant link between foot pain and the types of shoes men wear.
High-heels shoes could result in pain in later life for women.
While foot pain is a common complaint in the U.S. adult population foot and toe symptoms are among the top 20 reasons for physician visits
among those 65 to 74 years of age relatively little is known about the causes of foot pain in older adults. Women are more likely than men to have foot pain; however, it is not known if this is due to a higher prevalence of foot deformities, underlying disease, shoe wear, or other lifestyle choices.
From a list of 11 shoe types, study participants were asked about the one style of shoe they currently wear on a regular basis, what they regularly wore during five age periods in the past, and if they experience pain, aching or stiffness in either foot on most days.
Nearly 30 percent of women and 20 percent of men reported generalized foot pain, which is in line with other foot-pain studies.
Ms. Dufour’s team, however, found a significant association in women who reported hind-foot pain and past shoe wear that included high-heels and pumps.
The shoe types were classified as "poor" (high-heels, pumps, sandals and slippers), "average" (hard- or rubber-soled shoes and work boots), and "good" (athletic and casual sneakers). More than 60 percent of women reported wearing "poor" shoes in the past, compared to only 2 percent of men (13 percent of women said they currently wear "poor" shoes).
When we walk, a significant biomechanical shock is delivered to the foot each time our heel strikes the ground. "Good" shoes, such as sneakers and other athletic footwear, often have soles and other features that soften this shock and protect the foot. The heel and ankle take the brunt of this shock, which may be why women who wear high-heeled shoes often report pain in this part of the foot.
"Young women," says Ms. Dufour, "should make careful choices regarding their shoe types in order to potentially avoid hind-foot pain later in life."
Those persons suffering from rhinosinusitis has a high tendency to also suffer from depression due to their medical condition.
This was the result of a new study conducted on 73 patients wherein some 9.6 percent of these people suffered depression due to their condition.
The research also showed that 20.5 percent scored in the range of a major depressive disorder using an objective screening instrument with high sensitivity and specificity for diagnosing depression, the Patient Health Questionnaire-9.
Additionally, the disease-specific and general health-related quality of life (QOL) in these patients was worse than those who did not exhibit signs of depression.
Patients inflicted with rhinosinusitis better be careful since their medical condition could also result in depression.
Patients with depression and CRS scored significantly worse in most QOL measures, including bodily pain, and physical and social functioning. The authors believe this casts particular light on the impact of depression on diseases of the head and neck, which is to this point little is understood.
They contend that if physicians are to optimize their patients’ health, screening for both CRS and depression is warranted.
Pregnant women around the world should avoid high fat diet during their pregnancy.
This developed after a recent medical study has shown a mother’s diet of high fat could result in a severe form of liver disease in her child.
Based on the study made by the University of Southampton it was discovered that a high fat diet during a woman’s pregnancy makes her offspring more likely to develop a severe form of fatty liver disease when they reach adulthood.
It is said that non-alcoholic fatty liver disease (NAFLD) is a condition associated with obesity and caused by the build up of fat in the liver.
The condition advances in some people and it is important to understand the factors that contribute to disease progression. Until recently, NAFLD was considered rare and relatively harmless but now it is one of the most common forms of liver disease that may progress to cirrhosis a serious life threatening chronic liver disease.

Pregnant women should avoid high fat diet since it could lead to a liver disease.
Professor Christopher Byrne, with colleagues Dr Felino Cagampang and Dr Kim Bruce, of the University’s School of Medicine and researchers at King’s College London, conducted the study, funded by the BBSRC. Prof Byrne explained: "This research shows that too much saturated fat in a mother’s diet can affect the developing liver of a fetus, making it more susceptible to developing fatty liver disease later in life.
An unhealthy saturated fat-enriched diet in the child and young adult compounds the problem further causing a severe form of the fatty liver disease later in adult life."
The next stage of this research, also funded by the BBSRC, will be to understand, more precisely, the reason why fatty liver disease develops and to intervene to prevent the fatty liver disease occurring.
The University’s School of Medicine has a worldwide reputation for its pioneering research into the relationship between mothers’ diets in pregnancy and future health problems in their offspring.
Air pollution could lead to appendicitis
Author: admin
A latest medical study have shown that air pollution could lead to appendicitis.
The research, made by researchers at the University of Calgary, University of Toronto and Health Canada, looked at 5191 adults admitted to hospital in Calgary, Alberta, Canada. Fifty-two per cent of admissions occurred between April and September, the warmest months of the year in Canada during which people are more likely to be outside.
The dominant theory of the cause of appendicitis has been obstruction of the appendix opening, but this theory does not explain the trends of appendicitis in developed and developing countries. Appendicitis cases increased dramatically in industrialized countries in the 19th and early 20th centuries, then decreased in the middle and late 20th century, coinciding with legislation to improve air quality. The incidence of appendicitis has been growing in developing countries as they become more industrialized.
Using Environment Canada’s air pollution data for Calgary, the researchers determined the levels of ozone, nitrogen dioxide and other air-borne pollutants along with temperature.
The public needs to be careful since new pieces of evidence have shown that air pollution could lead to appendicitis.
They found correlations between high levels of ozone and nitrogen dioxide and the incidence of appendicitis between age groups and genders. More men than women were found to have the condition.
"For unexplained reasons, men are more likely than women to have appendicitis," write Dr. Gilaad Kaplan of the University of Calgary and coauthors. "Men may be more susceptible to the effects of outdoor air pollution because they are more likely to be employed in outdoor occupations," although they note that misclassifications of data could explain some of the difference.
While it is not known how air pollution may increase the risk of appendicitis, the authors suggest pollutants may trigger inflammatory responses. They recommend further studies to determine the link.
Here is a piece of good news to all those patients suffering from heart disease and cancer.
A recent medical research has shown that eating soybeans could cure and prevent heart ailments and cancer.
According to the study, soybeans contain high levels of several health-beneficial compounds including tocopherols, which have antioxidant properties.
These molecules can be used in the development of functional foods, which have specific health-beneficial properties and can be used in the treatment or prevention of diseases.
Tocopherols exist in four forms (a, ß, ?, and d) of which tocopherol is found in greatest concentration in soybeans.
However, a-tocopherol has the greatest antioxidant activity, and is the form converted to vitamin E in the human body. Thus, most interest for soybean tocopherols resides in a-tocopherol; however, certain health-properties have also been attributed to other tocopherol forms and interest for these remains. It has been suggested that all tocopherols could play a role in cardiovascular diseases and cancer prevention.
Although few studies have determined soybean tocopherols concentration in a range of genotypes or environments, none has investigated differences among several early-maturing genotypes grown in multiple environments.
Eating soybeans in a regular basis could keep you away from heart disease and cancer.
Such study allows for the determination of the tocopherols concentration range found in soybean, but also to determine how genotypes perform and compare to each other in contrasting environments. Such information is vital for both plant breeders and agricultural producers.
Researchers at McGill University, the Centre de Recherche sur les Grains, and Agriculture and Agri-Food Canada in Quebec have investigated tocopherols concentration and stability, with an emphasis on a-tocopherol, among early-maturing genotypes grown in multiple environments, and determined the relationship between tocopherols concentration and other important seed characteristics.
Their study was funded by research grants from the Ministère de l’Agriculture, des Pêcheries, et de l’Alimentation du Québec (MAPAQ) and the Natural Sciences and Engineering Research Council of Canada (NSERC). Results from the study are published in the September-October issue of Agronomy Journal. The research was also presented in Beijing, China at the 8th World Soybean Research Conference in August 2009.
Philippe Seguin, who led the study, stated "The large variation observed among genotypes for a-tocopherol, the relatively high stability of genotypes performance across environments, and the lack of negative correlation with other important seed characteristics suggest that selection for high a-tocopherol will be possible. Such characteristics will also help in the development of functional foods, which requires consistency in concentrations of health-beneficial compounds." Research is ongoing to identify factors affecting soybean tocopherols concentration.
Preliminary results suggest that both specific environmental factors and management practices, such as seeding date, could significantly affect concentrations.
Getting a better understanding of factors affecting soybean tocopherols concentration will help in the development of a new value-added use for soybean and thus to diversify markets for soybean producers.
A popular saying state that the eyes is the windows to the soul.
But recent medical research has shown that eyes is more than just a window for the soul since it can also offer important clues to your risk of heart disease and stroke.
Researchers of the Centre for Eye Research Australia (CERA) are currently doing an extensive study to prove that blood vessels in the retina at the back of the eye reflect changes in blood vessels in other parts of the body, especially the brain, kidneys and heart.
The team of medical experts believed that that blood vessels in the retina can be photographed and the images analysed by a computer to accurately determine a person’s risk of heart attack or stroke cardiovascular diseases that change the appearance of blood vessels in the eye.
Lead CERA researcher, Professor Tien Wong, explained through their study they wish to show that that combining this non-invasive retinal scan with the results from current risk assessment methods will improve precision and reliability in predicting cardiovascular disease.
Wong and his team has taken thousands of eye images and created a program that recognises common features of conditions that cause damage to be seen on the retina.
Your eyes is not only the window of the soul but also an indicator if a man suffers from a form of heart disease.
Once a person has symptoms of cardiovascular disease, damage has already been done to the body. So finding and treating high risk people early, even before they have symptoms, could minimise blood vessel damage and potentially avoid heart attack or stroke.
At present, doctors estimate a person’s statistical chance of developing cardiovascular disease by looking at individual factors such as whether they smoke, their family history, weight, blood cholesterol and blood pressure. Once you get symptoms, more extensive and sometimes invasive tests, such as angiogram are needed to confirm the result and assess severity of damage to the arteries of the heart or elsewhere.
Professor Wong said, "Results from the retinal scan would be delivered to GPs for a better picture of their patient’s health.
Dr. Christine Bennett, chair of the MBF Foundation Steering Committee and Bupa Chief Medical Officer*, went on to say, "This early assessment of the likelihood that a person will develop diseases like heart disease, stroke or even type 2 diabetes has the potential to significantly improve quality of life, reduce hospitalisations and the 50,000 deaths each year caused by cardiovascular disease."
Once a person knows their risk they may be able to delay the onset of developing cardiovascular disease by modifying their lifestyle accordingly.
"We know that smoking, too much alcohol, inactivity and poor nutrition are bad for our health but seeing the evidence not with, but in, your own eyes could be the wake-up call that triggers change," Bennett said.
