We hypothesized that persons with chronic fatigue syndrome (CFS) would have
a higher prevalence of metabolic syndrome compared with well controls, and
that unwell persons with insufficient symptoms or fatigue for CFS (termed
ISF) would have a prevalence of metabolic syndrome intermediate between
those with CFS and the controls. We also sought to examine the relationship
between metabolic syndrome and measures of functional impairment, fatigue,
and other symptoms. Our analysis was based on a population-based
case-control study conducted in metropolitan, urban, and rural areas of
Georgia, United States, between September 2004 and July 2005. There were 111
persons with CFS, 259 with ISF, and 123 controls. Metabolic syndrome was
determined based on having at least 3 of 5 standard risk components
(abdominal obesity, high triglycerides, high blood pressure, elevated
fasting glucose, and decreased high-density lipids) according to the
National Cholesterol Education Program Adult Treatment Panel III definition.
Persons with CFS were 2-fold as likely to have metabolic syndrome (odds
ratio = 2.12, confidence interval = 1.06, 4.23) compared with the controls.
There was a significant graded relationship between the number of metabolic
syndrome factors and CFS; each additional factor was associated with a 37%
increase in likelihood of having CFS. The association of ISF with metabolic
syndrome was weaker (odds ratio = 1.72, confidence interval = 0.94-3.16).
Among persons with CFS, the number of metabolic syndrome factors was
significantly correlated with worse fatigue on a standardized summary
measure of fatigue (r = 0.20, P = .04). In conclusion, CFS was associated
with metabolic syndrome, which further exacerbated fatigue. Published by

The primary symptom of fibromyalgia (FM) is chronic, widespread pain
accompanied by diffuse tenderness to light palpation. However, many patients
report a multitude of additional complaints and symptoms. Besides fatigue,
exhaustibility and stiffness, a decrease in concentration and memory are
further complaints that add significantly to the degree of suffering. This
complaint, often termed "fibrofog", is increasingly recognised as an
independent symptom that has made its way into the medical literature under
the term "dyscognition". Nonetheless there are only a few studies that have
specifically investigated neuropsychological deficits in FM patients in
order to further specify clinical complaints. The studies performed so far
have provided increasing evidence that FM patients have attention and
working memory deficits, which are most prominent when patients have to cope
with an additional source of distraction. With this review we intend to give
an overview of the neuropsychological studies in FM performed so far and to
assess possible implications for the underlying pathophysiology. In
addition, we discuss potential clinical approaches to these symptoms. A
systematic literature review up to June 2009 was carried out using the
keywords (pairs) "fibromyalgia" and "cognition", "fibromyalgia" and
"dyscognition", "fibromyalgia" and "cognitive deficits".

Maternal exposure to air pollution has been related to fetal growth in a
number of recent scientific studies. The objective of this study was to
assess the association between exposure to air pollution during pregnancy
and anthropometric measures at birth in a cohort in Valencia, Spain.
Seven hundred and eighty-five pregnant women and their singleton newborns
participated in the study. Exposure to ambient nitrogen dioxide (NO2) was
estimated by means of land use regression. NO2 spatial estimations were
adjusted to correspond to relevant pregnancy periods (whole pregnancy and
trimesters) for each woman. Outcome variables were birth weight, length, and
head circumference (HC), along with being small for gestational age (SGA).
The association between exposure to residential outdoor NO2 and outcomes was
assessed controlling for potential confounders and examining the shape of
the relationship using generalized additive models (GAM).
For continuous anthropometric measures, GAM indicated a change in slope at
NO2 concentrations of around 40 mcg/m3. NO2 exposure >40 mcg/m3 during the
first trimester was associated with a change in birth length of -0.27 cm
(95% CI: -0.51 to -0.03) and with a change in birth weight of -40.3 grams
(-96.3 to 15.6); the same exposure throughout the whole pregnancy was
associated with a change in birth HC of -0.17 cm (-0.34 to -0.003). The
shape of the relation was seen to be roughly linear for the risk of being
SGA. A 10 mcg/m3 increase in NO2 during the second trimester was associated
with being SGA-weight, OR: 1.37 (1.01-1.85). For SGA-length the estimate for
the same comparison was OR: 1.42 (0.89-2.25).
Prenatal exposure to traffic-related air pollution may reduce fetal growth.
Findings from this study provide further evidence of the need for developing
strategies to reduce air pollution in order to prevent risks to fetal health

A new report being released this month by Safer Chemicals, Healthy Families outlines the role of environmental contaminants in cancer, asthma, reproductive disorders, and other conditions. Learn about the report from a co-author and other leading researchers. Estimates of the proportion of the disease burden that can be attributed to toxic chemical exposures vary, ranging from 1 percent of all disease to 5 percent of childhood cancer, 10 percent of diabetes, Parkinson's disease, and neurodevelopmental deficits, and 30 percent of childhood asthma. A conservative estimate puts the health care cost savings attributable to a decline in the incidence of chronic disease due to reductions in chemical exposures at $5 billion per year. The report illustrates the opportunity to prevent disease and reduce health-care expenditures by overhauling the chemical management system in the United States. Speakers will be Charlotte Brody, RN, from Safer Chemicals Healthy Families; Richard Clapp, DSc, MPH, of Boston University School of Public Health; and Ted Schettler, MD, MPH, of the Science and Environmental Health Network.

Air pollution is associated with a wide range of adverse respiratory events. In order to study the mechanism associated with these effects, the relationships between fractional exhaled nitric oxide (FeNO), a potential marker of airway inflammation, and exposure to air pollution were examined in schoolchildren. FeNO was measured in 104 children (34 asthmatics and 70 non-asthmatics) drawn from the general population simultaneously with air pollution assessments (fine particles with an aerodiameter under 2.5 microm, nitrogen dioxide, acetaldehyde, and formaldehyde, with pumps and passive samplers) in schoolyards and classrooms. Asthmatics exhaled more FeNO than non-asthmatics. FeNO levels were significantly elevated in both asthmatic and non-asthmatic children exposed to high concentrations of formaldehyde, acetaldehyde, and PM(2.5). Differences between high versus low exposure in non-asthmatics resulted in an FeNO increase ranging from 45% for indoor acetaldehyde to 62% for indoor PM(2.5). Stronger associations were found in non-asthmatic children who were atopic, suggesting that atopic children may be more sensitive to air pollution than non-atopic children. Exposure to air pollution may lead to airway inflammation, as measured by FeNO, in schoolchildren. These associations occur even in children with no history of airway damage and seem to be enhanced in atopic subjects.

OBJECTIVE: The aim of this case series study was to investigate and report on patients with neuropathic pain who responded to treatment with omega-3 fatty acids. METHODS: Methods: Five patients with different underlying diagnoses including cervical radiculopathy, thoracic outlet syndrome, fibromyalgia, carpal tunnel syndrome, burn injury were treated with high oral doses of omega 3 fish oil (varying from 2400-7200 mg/day of EPA-DHA). Outcome measures were obtained pretreatment and posttreatment. These included validated surveys (short-form McGill Pain questionnaire, DN4 neuropathic pain scale, Pain Detect Questionnaire), objective clinical tools (Jamar grip strength, Lafayette dynamometry, tender point algometry) and EMG Nerve Conduction studies. RESULTS: These patients had clinically significant pain reduction, improved function as documented with both subjective and objective outcome measures up to as much as 19 months after treatment initiation. No serious adverse effects were reported. CONCLUSIONS: This first-ever reported case series suggests that omega-3 fatty acids may be of benefit in the management of patients with neuropathic pain. Further investigations with randomized controlled trials in a more specific neuropathic pain population would be warranted.

We studied the success and success factors of online support groups (OSGs) for patients, and the motives and goals of people who start such groups. We interviewed 23 webmasters of OSGs for patients with breast cancer, fibromyalgia and arthritis. The majority were women (n = 20) and most were patients (n = 21). Analysis of the interviews revealed that webmasters had altruistic and intrinsic motives for initiating an online support group. They defined success as the fulfilment of the goals they had in mind when they initiated their groups. To be able to make a group successful, decisions about its organization and management need to be coherent with these goals. Most webmasters stressed that promoting the group, keeping it alive and moderating the messages were vital success factors during the evolution stage. Management of the OSGs took up much of the webmasters' time and energy. On average webmasters were occupied with the group for 10-15 hours a week. Our study provides an overview of the pros and cons of differing decisions that have to be made when initiating an OSG.

EPA Increases Transparency on Chemical Risk Information
Comment: This really needs to go a step further to ensure transparency of ALL chemicals. Listing only chemicals with known substantial risk is not adequate. People should be able to discern all ingredients in products for allergy and sensitivity reasons. Waiting untili a chemical is proven a risk leaves the chance of many people being injured until studies are done. Being that 80% of chemicals have not been tested for human safety, this seems to be a lot of "feel good" publicity designed to calm the massses that doesn't really solve the problem it addresses in the way the public wants.
"More than two decades after parents dumped apples from children's lunch boxes because of concerns about a chemical applied to the fruit, most researchers agree the crop is safer although most of it still carries pesticide residue. Growers saw prices plunge after a 1989 television report led to widespread fears apples were coated in a cancer-causing chemical called Alar, used to enhance crunch and color. The public outcry led the government to ban some chemicals and increase oversight, while growers adopted new approaches to spraying apples and reduced the use of harsh chemicals."
