Risking Limb for Life? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Matthew Whitley Imagine you are walking alone in parking lot, when suddenly somebody grabs you by the arm and flashes a knife, demanding your money. Do you A) scream for help, B) try to wrestle the knife away, or C) remove your arm from your shoulder and make a break for it? Disarming your assailant may seem preferable to dis-arming yourself, but for a lizard option C is a likely response. A lizard tail left behind.

Risk of death by injury and autism

by Paul Whiteley in Questioning Answers

"Individuals with autism appear to be at substantially heightened risk for death from injury."That was the research bottom line published by Joseph Guan & Guohua Li [1] from Columbia University Medical Center, who trawled the accumulated data included in the US National Vital Statistics System screening death certificates issued between 1999 and 2014. Of the approximate 32 million death certificates issued, researchers found that some 1300 people diagnosed as on the autis........ Read more »

"Predisposition" to autoimmunity and inflammatory activation linked to autistic regression?

by Paul Whiteley in Questioning Answers

The paper by Ori Scott and colleagues [1] provides some very welcome interest in the concept of regression in relation to autism. As I've indicated quite a few times on this blog, regression accompanying cases of autism has [finally] been accepted by the research community at large (see here for example) but there is still some way to go with regards to the hows-and-whys of regression. There are some clues (see here) but more data is required. What the evidence available so far suggests is ........ Read more »

Publication Alert: High Nucleotide Resolution Study of the Skin Virome

by Geoffrey Hannigan in Prophage

A few weeks ago some colleagues and myself published a new manuscript looking at the diversity of the human skin virome. In our previous previous work, we evaluated the diversity of viruses on the skin. Other groups have looked at virus diversity at other body sites including the gut, lungs...... Read more »

One more time folks... pregnancy folate and autism risk

by Paul Whiteley in Questioning Answers

Folate yet again on this blog? Sorry but that's just how the peer-reviewed papers have fallen..."Maternal folate supplementation during pregnancy may reduce the risk of ASD [autism spectrum disorder] in the offspring, especially in the Western population."So said the meta-analysis by Yu and colleagues [1] reporting on a topic that has seen quite a lot of research interest down the years (see here). Authors this time around cumulatively examined data for some 4,500 cases of autism compared w........ Read more »

Novel FLCN mutations in Chinese patients

by Joana Guedes in BHD Research Blog

The gene FLCN is inactivated in individuals with BHD syndrome. The FLCN gene encodes the protein Folliculin, which is a putative tumour suppressor. Over 150 different FLCN mutations have been identified, most of which are likely to be pathogenic (LOVD-hosted FLCN mutation database). The majority of these mutations are frameshift, nonsense, insertion/deletion, or splice site mutations, resulting in truncation and inactivation of the encoded protein folliculin. FLCN consists of 14 exons spanning a........ Read more »

Folate-dependent one carbon metabolism and transsulfuration pathways: biomarkers for autism?

by Paul Whiteley in Questioning Answers

I found it a little unusual that the findings reported by Daniel Howsmon and colleagues [1] (open-access) talking about "multivariate statistical analysis presented herein [provided] unprecedented quantitative classification results for separating participants into ASD [autism spectrum disorder] and NEU [neurotypical] cohorts based solely on biochemical data" merited a rapid reply in a prominent science magazine pouring cold water on the results (see here). Not least bec........ Read more »

"a single intravenous infusion of autologous umbilical cord blood" and autism

by Paul Whiteley in Questioning Answers

'Could stem cells offer hope for autism?' went one media headline referencing the very preliminary "phase I, open-label trial" published by Geraldine Dawson and colleagues [1] (open-access) detailing the experiences of a single intravenous infusion of autologous umbilical cord blood in 25 children with "a confirmed diagnosis of ASD [autism spectrum disorder]."Well, the results were promising in respect of important issues such as safety in light of the tenet 'first do no harm': "Assess........

Paediatric congenital heart disease and autism risk (again)

by Paul Whiteley in Questioning Answers

"Risk of autism spectrum disorder screening status in children with congenital heart defects was higher than expected from population rates."So said the findings reported by Jessica Bean Jaworski and colleagues [1] who set about "to assess the rates of autism spectrum disorders in a large sample of children with a history of congenital heart defects and to assess medical, behavioral, and individual factors that may be associated with the risk of autism spectrum disorders." Covering a topic that ........ Read more »

Autism, ageing and comorbidity

by Paul Whiteley in Questioning Answers

I'm not spending too much time today on the findings published by Elizabeth Wise and colleagues [1] but did want to bring them to your attention. Looking at the presentation of "comorbidities and behavioral and neuropsychiatric symptoms" in relation to autism in the context of ageing, some important details were noted. Not least that "GI [gastrointestinal] disorders (68.9%) and seizure disorders (23%) were common, and 25.7% of the sample had a BMI [body mass index] >30" wh........ Read more »

Financial Scam Vulnerability: Brain Risk Factors

by William Yates, M.D. in Brain Posts

It is always frustrating when you hear about a financial scam that has target a vulnerable population like the elderly population.Elderly individuals may be targeted for a variety of reasons. First, they often have financial resources. Second, they may be a generally more trustworthy group increasing risk for falling for a scam. Third, elderly may suffer from some age-related brain changes that impair cognition and judgment.A recent research study suggests specific brain deficits may increase vu........ Read more »

Decreased urinary creatinine levels associated with autism (again)

by Paul Whiteley in Questioning Answers

One finding in particular stood out from those reported by Lussu and colleagues [1] following some nifty metabolomic investigations: decreased levels of urinary creatinine in their cohort of participants diagnosed as on the autism spectrum (n=21) compared with "controls (n = 21), these being siblings of autistic patients."Based on the "use of 1 H-NMR metabolomics to analyze the global biochemical signature of ASD [autism spectrum disorder] patients" researchers turned again to a fa........

On the under-studied populations within the autism spectrum

by Paul Whiteley in Questioning Answers

I don't typically post on a Sunday, but given that today - 2nd April - is World Autism Awareness Day I've decided to make an exception. The theme of today's post is based around the notion that the autism spectrum is truly wide and heterogeneous, and although this is fairly universally acknowledged, the current peer-reviewed research literature on autism is perhaps not yet so accepting. So...Consistent with the idea that scientific research seems to go through cycles of themes/interests, th........ Read more »

Yet more bumetanide and autism findings

by Paul Whiteley in Questioning Answers

Bumetanide, a loop diuretic medicine typically used to treat heart failure, is probably not something that most people would associate with 'attenuating' some of the presented characteristics of autism. This Na-K-Cl cotransporter (NKCC) blocking drug (influencing chloride concentrations in neurons and impacting on the actions of gamma-Aminobutyric acid, GABA) has however made quite a few appearances in the peer-reviewed autism research literature (see here and see here) and beyond........

Coeliac disease, autism and more

by Paul Whiteley in Questioning Answers

"Compared with the general population, children with celiac disease had a 1.4-fold greater risk of future psychiatric disorders. Childhood celiac disease was identified as a risk factor for mood disorders, anxiety disorders, eating disorders, behavioral disorders, ADHD [attention-deficit hyperactivity disorder], ASD [autism spectrum disorder], and intellectual disability."So said the study findings reported by Agnieszka Butwicka and colleagues [1] who, yet again, relied on one of ........

[Objective] exposure to flame retardants and social behaviours

by Paul Whiteley in Questioning Answers

Although a few details of the study reported by Shannon Lipscomb and colleagues [1] (open-access) interested me, I was particularly taken by their use of "a silicone passive wristband sampler [worn] around his/her wrist or ankle" to "assess the child’s exposure to flame retardants" as part of their investigation "to determine if flame retardant exposure was associated with measurable differences in social behaviors among children ages 3–5 years."I've covered the topic of potential adver........
