Mental Attitude: Mental Stress Affects Male and Female Hearts in Different Ways.
Past studies have suggested that mental stress can influence heart health. Now, researchers have found that women under mental stress are more likely than men to experience reduced blood flow to the heart and are also more prone to clots due to platelet aggregation. On the other hand, men experience greater changes in blood pressure and heart rate in response to mental stress. Researcher Dr. Zainab Samad adds, “The relationship between mental stress and cardiovascular disease is well-known. This study revealed that mental stress affects the cardiovascular health of men and women differently. We need to recognize this difference when evaluating and treating patients for cardiovascular disease.”

Health Alert: Possible Link Between Breast Implants and Cancer.
An international research group has concluded that breast implants can cause a new subtype of rare, yet malignant, lymphoma known as anaplastic large cell lymphoma (ALCL). This type of cancer is usually found in lymph nodes, skin, lung, liver, and soft tissue, but is not usually found in the breast. The researchers found that cases in which ALCL developed in the breast were almost exclusively involved individuals with breast implants. The actual reasons why breast implants can cause lymphoma are currently unknown, but the research team suspects the cause is an abnormal immune response. In many cases, the lymphoma subsided once the implants were removed.

Diet: A Chemical in Broccoli May Help Treat Autism.
Sulforaphane, a chemical found in broccoli and other cruciferous vegetables, shows promise for improving some behavioral symptoms of autism. Researchers found that about two thirds of participants who received sulforaphane saw their scores on the Aberrant Behavior Checklist reduced by 34%, while their scores on the Social Responsiveness Scale fell 17%. They hope to discover the biology underlying the effects observed and to study them at a cellular level.

Exercise: Heavy Exercise Can Produce Asthma-Like Symptoms in Healthy Kids.
Researchers have found that children who undergo brief periods of intense exercise can exhibit lung dysfunction and other symptoms similar to those experienced by asthma patients. These symptoms can happen even when the child has no history of asthma. Lead researcher Dr. Alladdin Abosaida adds, “We did not expect to see pulmonary function abnormalities after short periods of heavy exercise in such a large number of healthy children in our subject population.” Further research is needed to determine the mechanism of lung dysfunction in children following heavy exercise and identify possible interventions.

Chiropractic: Immediate Changes in Brain After Manual Therapy in Patients with Pain.
New research focused on the effects of manual therapies on pain modulation has revealed that therapies such as chiropractic spinal manipulation, spinal mobilization, and therapeutic touch have an immediate effect on the functional connectivity between brain regions involved in processing and modulating the pain experience. The results were gathered by using functional magnetic resonance imaging of the brain combined with measurements of pain sensitivity and intensity. The findings suggest that manual therapies may lead to neurophysiologic changes that result in pain relief.

Wellness/Prevention: Babies Benefit if Mothers Follow Lifestyle Advice During Pregnancy.
In the largest study of its kind, researchers gave nutrition and exercise advice to pregnant women who were either overweight or obese. Women who received such advice increased their fruit and vegetable intake and reduced saturated fat intake. They also engaged in 15-20 minutes of brisk walking on most days of the week. Their babies were more likely to have a healthier birth weight, less likely to have a moderate to severe respiratory distress syndrome, and were able to go home sooner than babies born from mothers in a control group that did not receive any diet or exercise advice. The researchers hope that by following some simple, practical, and achievable lifestyle advice, overweight pregnant women can improve both their own health and the health of their babies.
