A few-foods diet for ADHD: a systematic review of meta-analyses of double-blind, placebo-controlled trials

by Paul Whiteley in Questioning Answers

"... the effect sizes of a few-foods diet are medium to large, justifying implementation of a diagnostic FFD [few-foods diet] in subgroups of children with ADHD [attention-deficit hyperactivity disorder], thus offering innovative treatment opportunities for ADHD."So said the "Systematic Review of Meta-Analyses of Double-Blind Placebo-Controlled Trials" published by Lidy Pelsser and colleagues [1] (open-access available here) looking at various dietary interventions that have ........

On dietary and nutritional therapies for ME/CFS

by Paul Whiteley in Questioning Answers

ME/CFS in case you don't already know refers to Myalgic Encephalomyelitis / Chronic Fatigue Syndrome and, according to the findings reported by Nadia Campagnolo and colleagues [1], is in need of quite a bit more scientific investigation when it comes to the application of dietary changes and nutritional supplements to potentially alter the course of the condition(s).Surveying the peer-reviewed literature "from 1994 to May 2016" the authors looked for peer-reviewed studies where "CFS/ME........

Timing and Attention Matter in Dog Training, New Study Shows

by CAPB in Companion Animal Psychology Blog

Analysis of videos of dog training sessions show that getting the dog’s attention and good timing of rewards are linked to better results.A new study looks at the interactions between people and dogs whilst teaching ‘lie down’. The results show the importance of the timing of rewards and of getting the dog’s attention in order to be successful in dog training.The study is part of a wider research project at the University of Sydney into what they call “dogmanship.” I asked first auth........

Sex, alcohol, and structural variants in fission yeast

by Christophe Dessimoz in Open Reading Frame

Our latest study just came out (Jeffares et al., Nature Comm 2017). In it, we carefully catalogued high-confidence structural variants among all known strains of the fission yeast population, and assessed their impact on spore viability, winemaking and other traits. This post gives a summary and the story behind the paper.

Structural variants (SVs) measure genetic variation beyond single nucleotide changes …

On atopic disease and ADHD: 'strong evidence' for an association

by Paul Whiteley in Questioning Answers

"This current systematic review provides strong evidence that ADHD [attention-deficit hyperactivity disorder] is associated with atopic diseases and that individuals have a 30% to 50% greater chance of developing ADHD compared to controls."So said the results of the systematic review and meta-analysis published by Jurjen van der Schans and colleagues [1] looking at the collected peer-reviewed science literature on how conditions such as asthma, eczema and rhinitis might increase t........

Biofouling successional processes

by SciELO in SciELO in Perspective | Press Releases

To assess the successional pattern of fouling organisms we tested the hypothesis that depth, light intensity and predation influences the trajectory of the fouling community. The results suggest that each physical factor or biological process can change the successional trajectory, and the respective model (e.g., convergent, divergent, parallel, or cyclic) depends on the magnitudes of the determinants that act on the community at each stage of its trajectory. … Read More →...

Accepting the morally outrageous: Is this our new normal? 

by Doug Keene in The Jury Room

Some interesting research is described in plain language over at the Vox website by Joshua Knobe (an academic from Yale). The article highlights a question we’ve been wondering about that may be important for all of us to consider over the next four years as we plan strategies for litigation. The question is this: Just […]... Read more »

Natural course of "chronic disabling fatigue" in adolescents

by Paul Whiteley in Questioning Answers

"We use the term 'chronic disabling fatigue' (CDF) because CFS/ME [chronic fatigue syndrome / myalgic encephalomyelitis] was not verified by clinical diagnosis."That was one of the important details included in the findings reported by Tom Norris and colleagues [1] (open-access) who "aimed to describe the epidemiology and natural course of CFS/ME in adolescents aged 13–18 years."

ADHD, obesity and bariatric surgery?

by Paul Whiteley in Questioning Answers

"The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD [attention-deficit hyperactivity disorder]. It can be hypothesized that some core ADHD symptoms improve after surgery."Bariatric surgery, where several surgical options are available to aid weight loss in those who present with 'dangerous' obesity, was the topic of the paper by Nielsen and colleagues [1] (open-access available here) who set out to compare "pre- and........

Brain Shape and Personality Type

by William Yates, M.D. in Brain Posts

Personality has often been conceptualized a a human feature shaped largely by nurture and environment.Unlike major neuroscience medicine disorders, personality features have been considered less influenced by brain structure and genetic influences.A recent brain structure (morphology) study puts these assumptions at risk.Roberta Riccelli along with colleagues in Italy and Florida State University studied brain structural features across 507 participants in the Human Connectome Project.All subjec........

"Schizophrenia confers a high endogenous risk for diabetes"

"Schizophrenia confers a high endogenous risk for diabetes, and the risk is further increased by both first-generation and second-generation antipsychotics."So concluded Anto Rajkumar and colleagues [1] who relied on participant data in the thousands derived from several of those very helpful Scandinavian population registries (this time in Denmark) to add some further science to the idea that psychiatric diagnoses like schizophrenia seem to carry an elevated risk for all-manner of somatic ........

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........

Preprints – the way forward for rapid and open knowledge sharing

by SciELO in SciELO in Perspective

Preprints – versions of academic articles that have not yet been formally peer-reviewed before publication – are gaining acceptance in the academic world. They deliver open access as well as speedy publication, and their decades old success in physics has spurred on their spread in other disciplines. The development of preprints is accelerating; important funding agencies are in support of them, and also SciELO is planning to set up a preprint server for authors in Latin America and the Glob........
