(Press-News.org) Rome, Italy, 11 June 2015: The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference showed that people with systemic sclerosis (SSc) have a unique bacterial signature in their colon, when compared with healthy people. These findings suggest that changes in the gut ecology could contribute to the clinical symptoms of SSc, and could be used to diagnose the condition, and in the development of alternative treatments.
Systemic sclerosis (SSc) is an autoimmune disease affecting multiple organs. Up to 90% of people with SSc will suffer from gastrointestinal tract involvement, which causes symptoms ranging from reflux, difficulty swallowing and feeling bloated or full, to diarrhoea, constipation and faecal incontinence.
"Although gastrointestinal tract dysfunction is a major cause of morbidity and mortality in patients, its aetiology has always remained elusive," said study investigator Dr. Elizabeth Volkmann, University of California, Los Angeles, David Geffen School of Medicine, United States. "By identifying significant differences in bacteria - both in type and quantity - seen in the colons of healthy individuals and those with SSc, we hope to have pinpointed the exact changes in body ecology that may contribute to the clinical symptoms of this disease. We believe investigating this specific microbial signature further has the potential to lead to better diagnostic tools and treatment for a truly debilitating condition."
Seventeen patients with SSc underwent colonoscopy, and were scored for distention/bloating, faecal soilage (incontinence), diarrhoea, constipation, emotional wellbeing and social functioning. The composition of microbial communities in the first part of the large intestine (caecum) and last part of the large intestine (sigmoid) were compared with healthy individuals.
The data showed significant differences between patients with SSc and healthy individuals, with a marked reduction in specific bacteria known to supply essential nutrients (commensal bacteria; Bacteroides and Faecalibacterium), and increases in bacteria causing infection (pathogenic bacteria; Enterobacteriales and Fusobacterium). This is the first study to directly examine the microbial makeup of the colon, and suggests that an imbalance in bacteria is a feature of SSc.

Rome, June 11 -- New recommendations by EULAR for women's health and pregnancy in patients with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS) were presented today at the European League Against Rheumatism Annual Congress (EULAR 2015). Developed by expert consensus, these evidence-based recommendations provide crucial guidance to support family planning, assisted reproduction, pregnancy and the menopause in these patients.
'APS and SLE disproportionately affect women, typically starting when they are at their most fertile, and leaving women ...
The constant movement of children with attention-deficit/hyperactivity disorder (ADHD) may be distracting -- but the fidgeting also may improve their cognitive performance, a study by researchers with the UC Davis MIND Institute has found.
The study of pre-teens and teenagers with ADHD examined how movement -- its intensity and frequency -- correlated with accuracy on cognitively demanding tasks requiring good attention. It found that participants who moved more intensely exhibited substantially better cognitive performance.
The study, "A trial-by-trial analysis reveals ...
Researchers studying banded mongooses in Uganda have discovered that these small mammals are able to discriminate between relatives and non-relatives to avoid inbreeding even when mating within their own closely related social group.
Inbreeding can be a big problem for social species such as banded mongooses because they grow up in social groups consisting mainly of close relatives. This study is the first to suggest that social animals are able to avoid the costs of inbreeding without relying on un-related mating partners from other social groups.

A new study published today by the scientific journal Addiction finds that in England, children's exposure to second-hand smoke has declined by approximately 80% since 1998.
Also, an emerging social norm in England has led to the adoption of smoke-free homes not only when parents are non-smokers but also when they smoke. The proportion of children living in a home reported to be smoke-free increased from 63% in 1998 to 87.3% in 2012.
The study gathered data from over 35,000 children who participated in the annual Health Survey for England (HSE) from 1998 to 2012. ...
Pregnant women can improve their health and even reduce the risk of complications during childbirth by maintaining a healthy weight through diet and exercise. Research has shown that gaining too much weight during pregnancy increases the risk of gestational diabetes, high blood pressure, large babies, and delivery by caesarean section; and newborns with large birth weights are at risk of childhood obesity.
An updated systematic review published in The Cochrane Library reveals that diet or exercise interventions, or a combination of both, can prevent excessive weight gain ...
Weekend screen time is linked to poorer teen bone health--but only in boys, reveals research published in the online journal BMJ Open.
The apparent lack of impact of leisure screen time on teen girls' bone health may be explained by their different body fat distribution, suggest the researchers.
They base their findings on participants in the Tromsø Fit Futures Study in Norway, which involved 961 of the region's 15-17 year old school pupils in 2010-11 (first wave) and 688 (66%) of this original group two years later in 2012-13 (second wave).
At both time periods, ...
Aerobic exercise seems to curb the severity of asthma symptoms and improves quality of life, finds a small study published online in the journal Thorax.
It should be routinely added to the drug treatment of moderate to severe asthma, suggest the researchers, who point out that people with asthma often avoid exercise for fear of triggering symptoms.
Exercise has been recommended in the past for asthma patients, because it improves physical fitness, overall quality of life, and reduces the need for inhalers. But it has not been clear whether the pros outweigh the cons.

Pyrazine additives in low tar ('light') and e-cigarettes may be reinforcing the addictive qualities of nicotine, and should be strictly regulated, concludes research published online in the journal Tobacco Control.
The evidence suggests that pyrazines have sensory and pharmacological effects which act independently of, and in tandem with, nicotine, and were developed by the tobacco industry to make low tar ('light') cigarettes taste richer and smoother, and boost sales.
Nicotine dependence is a complex process, but is primarily caused by the ability of nicotine to prompt ...
Sexual assault resistance training works, according to a new University of Windsor-led study published today in the New England Journal of Medicine. While only those who commit acts of sexual violence can stop sexual assault, women may be able to reduce the likelihood that they will be the victim of a completed rape. To use a medical analogy, there is not much we can do about pathogens such as bacteria or viruses already in our environment, but we can take steps to boost our immune system so we can better resist these pathogens when we come into contact with them. This ...
