Hyperuricemia present in both medicated and unmedicated kids with autism

by Paul Whiteley in Questioning Answers

I was intrigued to read the findings reported by Natchaya Vanwong and colleagues [1] talking about the presence of hyperuricemia - an excess of uric acid in the blood - in their cohort of children and young adults diagnosed with an autism spectrum disorder (ASD). Intrigued not only because the authors discuss how the use of the atypical antipsychotic risperidone might *correlate* with elevations of uric acid but also how: "Hyperuricemia was present in 44.70% of risperidone-naïve patients w........

Autism and a 'clear' reduction of behavioural severity in cases diagnosed

by Paul Whiteley in Questioning Answers

"This study provides the first clear evidence of a reduction over time in the behavioral severity of individuals diagnosed with Autistic Disorder during a period of stability in diagnostic criteria."So said the study findings reported by Andrew Whitehouse and colleagues [1] (a man not afraid to make waves when it comes to thinking about autism or about approaches to intervention) looking at "whether there were changes over time in the qualitative and quantitative phenotype of individuals wh........

S100B protein and autism continued

by Paul Whiteley in Questioning Answers

"Our findings showing an increase in peripheral concentrations of S100B and TNF-α provide limited support to the hypothesis about the roles of altered immune function and S100B in autism spectrum disorder (ASD)."So said the findings reported by Selin Aktan Guloksuz and colleagues [1] (open-access available here) continuing some discussions a few years back on a possible role for S100B in relation to at least some autism (see here).S100B - S100 calcium-binding protein B - is a compound invo........

High frequency of (self-reported) ADHD symptoms in eating disorders

by Paul Whiteley in Questioning Answers

"There is a high frequency of ADHD [attention-deficit hyperactivity disorder] symptoms in patients with binge eating/purging eating disorders that motivates further studies."That was the conclusion reached in the study by Nils Erik Svedlund and colleagues [1] (open-access) who, among other things, set out to "explore the prevalence and types of self-reported ADHD symptoms in a large, unselected group of ED [eating disorder] patients assessed in a specialized ED clinic." ........

"Should gluten-free foods be available on prescription?"

by Paul Whiteley in Questioning Answers

Continuing the theme of blogging outside of the core material typically included on this site, I couldn't resist a mention of the 'head-to-head' debate talked about in the article by Matthew Kurien and colleagues [1] published in the British Medical Journal (BMJ).As per the title of this post, the name of the game was gluten-free products being available on prescription here in Blighty, and in particular, the prescribing of gluten-free products to patients diagnosed with coeliac disease.

TSC1 expression is affected by VHL alterations and HIF-1α production in clear-cell RCC

by Joana Guedes in BHD Research Blog

VHL genetic alterations do not affect the production of HIF-α in clear-cell renal cell carcinoma (ccRCC). However, their effects on tuberous sclerosis proteins (TSC1/2) and heat shock protein 90 (Hsp90) expression are currently unknown. In a recent study, Damjanovic et al. (2016) evaluated the impact of VHL genetic alterations and HIF-α production on the expression of TSC proteins and Hsp90 in 47 sporadic ccRCCs and corresponding normal tissues.... Read more »

Vitamin D deficiency and risk of dementia

by Paul Whiteley in Questioning Answers

"The results of this systematic review show that low vitamin D levels might contribute to the development of dementia."Whilst slightly off-topic when it comes to the core research material typically included on this blog, I did want to bring to your attention the systematic review and meta-analysis results published by Isolde Sommer and colleagues [1] (open-access) for your perusal. Although unable to "identify a single study investigating the association between sunlight exposure and demen........ Read more »

Andrew Whitehouse on challenging yet another autism status quo: diagnosis before intervention

by Paul Whiteley in Questioning Answers

"This paper provides an overview of the benefits and drawbacks of the current clinical pathway that places primacy on a diagnostic assessment for triggering the commencement of therapy. The paper then presents an alternative clinical pathway - the identification and provision of therapy to infants at risk of ASD [autism spectrum disorder] - and provides a critical review of current evidence supporting this model."So said the 'lecture paper' by Andrew Whitehouse [1] and, as per the titl........

Jet Lag and Baseball (MLB) Performance

by William Yates, M.D. in Brain Posts

Abrupt changes in the biological clock or circadian rhythm are noted to contribute to significant cognitive and psychomotor impairments.One practical area for this effect to potentially be important is in the area of sports performance.Alex Song and colleagues recently completed an interesting study of major league baseball (MLB) performance related to team travel patterns.The major leagues are divided into regional divisions (western, central and eastern) to minimize length of travel to and fro........

A poo transplant for [some] autism?

by Paul Whiteley in Questioning Answers

I've talked about 'fecal microbial transplants' a.k.a the poo(p) transplant before on this blog (see here). That previous entry was about the more typical (and potentially life-saving) use of a poo transplant - where stool from one person is extracted, 'repackaged' and transferred to another person - albeit with caveats in terms of possible long-term side-effects. Now it appears that poo transplants are being investigated with something rather more central to the typical cont........

Autism and visual impairment reviewed

by Paul Whiteley in Questioning Answers

Of the various autism science journals out there in peer-reviewed (La-La!) land, one journal in particular is really starting to grow on me: [The] Review Journal of Autism and Developmental Disorders.I like this journal because it is basically systematic review and meta-analysis heaven when it comes to the quite voluminous autism research literature and seems to publish some real gems (see here for example).Another paper from this journal caught my eye recently by Maggie Butchart and colleagues ........

Fatty acids 'for autism'? Meta-analysis says probably not but...

by Paul Whiteley in Questioning Answers

"Because of the limited number of included studies and small sample sizes, no firm conclusions can be drawn. However, the limited data currently available suggest that ω-3 FA [fatty acid] supplementation does not enhance the performance of children with ASD [autism spectrum disorder]."Those were the conclusions reached in the systematic review and meta-analysis paper published by Andrea Horvath and colleagues [1] looking at the collected peer-reviewed literature on the topic up t........

Autism diagnoses (and diagnostic stability) in Germany

by Paul Whiteley in Questioning Answers

"From 2006 to 2012, the prevalence of autism spectrum disorder diagnoses in 0- to 24-year-olds increased from 0.22% to 0.38%."That was one of the details included in the rather interesting paper by Christian Bachmann and colleagues [1] who provided some introductory information on the the trends in autism diagnoses in Germany. I say 'introductory information' because it appears that autism or autism spectrum disorder (ASD) has not exactly received the research attention in Germany that it p........ Read more »

Nature Shapes Faithful and Unfaithful Brains

by Miss Behavior in The Scorpion and the Frog

Among monogamous animals, some individuals are more faithful than others. Could these differences in fidelity be, in part, because of differences in our brains? And if so, why does this diversity in brain and behavior exist?A snuggly prairie vole family. Photo from theNerdPatrol at Wikimedia Commons.Prairie voles are small North American rodents that form monogamous pair bonds, share parental duties, and defend their homes. Although prairie voles form monogamous pairs, that does not mean they ar........ Read more »
