Let those who never smelled bad cast the first stone

by Aurametrix team in Aurametrix Blog

Analysis of our metabolism is crucial to comprehending the responses of our genes and microbes to the stresses of daily life, and to elucidating the causes and consequences of health and disease. And measurement of urinary metabolites - small molecules produced from foods, drinks, drugs, environmental contaminants, bodily waste products and bacterial by-products - is key to the analysis. We applied this approach to an elusive condition that has always evaded diagnosis: s........

Vitamin D genes and autism

by Paul Whiteley in Questioning Answers

"Vitamin D deficiency is a putative environmental risk factor for autism spectrum disorder (ASD)."And..."We provide straightforward genetic evidences for the first time that VDRGs [vitamin D-related genes] with a strong degree of DNM [de novo mutations] burden in ASD and DNMs of VDRGs could be involved in the mechanism underlying in ASD pathogenesis."That was the research bottom line reported on by Jinchen Li and colleagues [1] examining an important part of the whole 'vitami........

Congenital heart disease and autism and ADHD: Taiwan wades in

by Paul Whiteley in Questioning Answers

"The incidence rates of perinatal comorbidities, EDD [early developmental disorders], ADHD [attention-deficit hyperactivity disorder], and ASD [autism spectrum disorder] were higher in the CHD [congenital heart disease] group than in the control group."So said the findings reported by Pei-Chen Tsao and colleagues [1] investigating an issue that has cropped up more than once on this blog in relation to the developmental/behavioural correlates possibly associated with........

Trends in ADHD medication use in the US and Europe: is this a bad thing?

by Paul Whiteley in Questioning Answers

I don't want to dwell too much on the findings reported by Christian Bachmann and colleagues [1] observing that in five Western countries - Denmark, Germany, the Netherlands, the United Kingdom (UK) and the United States (US) - ADHD (attention-deficit hyperactivity disorder) medication use between 2005/2006-2012 was on the increase. But I do think it is important to mention some of the implications from such figures and some of the positives and negatives associated with such generated........ Read more »

Self-reported sexual attraction and autism

by Paul Whiteley in Questioning Answers

The findings reported by Tamara May and colleagues [1] are discussed today, looking at self-reported sexual attraction and past sexual relationships among adolescents diagnosed with an autism spectrum disorder (ASD) compared with not-autism controls.Asking 14-15 year olds who took part in The Longitudinal Study of Australian Children (94 diagnosed with autism and some 3400 controls) some rather personal questions, researchers reported that: "ASD males reported fewer prior boyfriends/gi........

ADHD and suicide

by Paul Whiteley in Questioning Answers

"There is a positive association between ADHD [attention-deficit hyperactivity disorder] and suicidality in both sexes and in all age groups."So said the results of the systematic review published by Balazs & Kereszteny [1] (open-access available here) who surveyed the recent peer-reviewed literature on the topic between 2011 and 2015. Reporting results based on findings included in 26 papers, authors concluded that suicidality - ideation, behavior, attempts, and suicide ........ Read more »

Mitochondrial mutations are not common in chronic fatigue syndrome but...

by Paul Whiteley in Questioning Answers

"We report the complete mtDNA [mitochondrial DNA] sequence of 93 CFS [chronic fatigue syndrome] patients from the UK and RSA, without finding evidence of clinically proven mtDNA mutations."So said the results reported by Elizna Schoeman and colleagues [1] (open-access available here) who drew on other research previously covered on this blog (see here) suggesting that "symptoms of mitochondrial diseases and CFS frequently overlap and can easily be mistaken" to look-see whether iss........

Sharing the Future with Artificial Intelligence

by Aurametrix team in Aurametrix Blog

Artificial intelligence has reached a buzzword utopia as it seems everyone is talking about self-driving cars, delivery drones and virtual assistants with human-like "intelligence." Some believe this new era of AI will make the American Dream universally accessible, enabling early retirement in bucolic settings. Others are concerned about a greater inequality created by a jobless future.... Read more »

On abuse exposure and mate selection

by Paul Whiteley in Questioning Answers

The paper by Andrea Roberts and colleagues [1] is offered up for brief discussion today, and a slightly uncomfortable but nonetheless potentially important set of results that "provide evidence that childhood abuse affects mate selection, with implications for offspring health."I tread very carefully with this topic but was intrigued by the findings looking at whether 'offspring health' in the context of the presence of autism or autism spectrum disorder (ASD) might be at least sometimes mediate........

When grandmothers smoked during pregnancy...

by Paul Whiteley in Questioning Answers

Please, do not smoke during pregnancyALSPAC - the Avon Longitudinal Study of Parents and Children - continues to give in research terms as today I want to mention the findings reported by Jean Golding and colleagues [1] (open-access) observing "an association between maternal grandmother smoking in pregnancy and grand daughters having adverse scores in Social Communication and Repetitive Behaviour measures that are independently predictive of diagnosed autism."The study results have garnere........

Autism, pregnancy maternal immune activation and vitamin D?

by Paul Whiteley in Questioning Answers

Today's post is a bit of a mash-up, drawing on two articles quite recently published in the peer-reviewed science domain.The first is by Stephanie Vuillermot and colleagues [1] (open-access) suggesting that "early dietary supplementation with vitamin D may open new avenues for a successful attenuation or even prevention of neurodevelopmental disorders following maternal inflammation during pregnancy." These findings have also received some media attention (see here for example) and continue........ Read more »

Is screen time a risk factor for ADHD?

by Paul Whiteley in Questioning Answers

The findings reported by Vivien Suchert and colleagues [1] observing that "screen time, but not other non-screen-based sedentary activities should be considered as being a risk factor for ADHD [attention-deficit hyperactivity disorder]" taps into long-running debates on whether our societal obsession with watching, clicking and swiping might not be 'a totally positive thing' when it comes to psychological development, health and wellbeing.Yes, I know this is a complicated area ful........

Hornig, Lipkin and chronic fatigue syndrome again

by Paul Whiteley in Questioning Answers

Drs Mady Hornig and Ian Lipkin once again provide some fodder for this blog, continuing one of their important research themes on how chronic fatigue syndrome (CFS) (sometimes also referred to as myalgic encephalomyelitis, ME) might show some important immune-related issues [1].This research tag-team and the teams of dedicated scientists who surround them are making some real progress with regards to the idea that ME/CFS is a physical condition (not psychosomatic and not 'biopsychosocial') ........

Who'd have thunk it: physical activity inversely associated with BMI and body fat percentage

by Paul Whiteley in Questioning Answers

"In this sample of middle-aged adults, drawn from the general population, physical activity was inversely associated with BMI [body mass index] and body fat percentage. For people with the same BMI, those who were more active had a lower body fat percentage."Those were the conclusions made by Kathryn Bradbury and colleagues [1] (open-access) drawing on data derived from "cross-sectional analysis of participants recruited into UK Biobank in 2006–2010." Said results continue a res........ Read more »

Sensory issues in adult ADHD controlling for autistic symptoms...

by Paul Whiteley in Questioning Answers

I was intrigued to read the paper by Bijlenga and colleagues [1] reporting on "the prevalence of sensory hyper- and hyposensitivity among adults with ADHD [attention-deficit hyperactivity disorder], controlling for autistic symptoms."The authors concluded that among their cohort of over 100 adults diagnosed with ADHD, both sensory hyper- and hyposensitivity symptoms as described by response to the Adolescent/Adult Sensory Profile-NL (AASP-NL), were over-represented compared w........

Autistic adults as critical autism experts (with research caveats)

by Paul Whiteley in Questioning Answers

"Findings suggest that autistic adults should be considered autism experts and involved as partners in autism research."That was the conclusion reached in the paper by Kristen Gillespie-Lynch and colleagues [1] (open-access) reporting on the results of an online survey assessing "autism knowledge and stigma among 636 adults with varied relationships to autism, including autistic people and nuclear family members." Among the various groups of people who contributed to the survey, several vie........ Read more »

Parental exposures and risk of offspring autism: some curious details

by Paul Whiteley in Questioning Answers

"Overall, our results were consistent with no positive association between parental asthmagen exposure and ASD [autism spectrum disorder] in the children."So said the findings reported by Alison Singer and colleagues [1] (open-access) continuing a research theme from this group [2] looking at whether "parental workplace exposures to risk factors for asthma (“asthmagens”)" might have relevance to offspring risk for autism.Based on data derived from some of those oh-so-important Scan........

"a gradual decline in recorded diagnoses of CFS/ME since 2001"?

by Paul Whiteley in Questioning Answers

The quote forming the title of today's post comes from the paper by Simon Collin and colleagues [1] (open-access available here) who, based on analysis of the UK "Clinical Practice Research Datalink (CPRD), formerly known as the General Practice Research Database (GPRD)" set out to look at the "Incidence of CFS/ME [chronic fatigue syndrome/ myalgic encephalomyelitis], FM [fibromyalgia], post-viral fatigue syndrome (PVFS), and asthenia/debility."
