Depression, SMILES and Modified Mediterranean diet (advice)

by Paul Whiteley in Questioning Answers

SMILES in the title of this post refers to the SMILES trial - Supporting the Modification of lifestyle In Lowered Emotional States - and results recently published by Felice Jacka and colleagues [1] (open-access) pertinent to the idea that "dietary improvement" might be something to consider when a diagnosis of major depressive episode (MDE) is received.Having previously published their study protocol [2], researchers set about looking at whether under "single blind, randomised controlled" ........

More than Meets the Eye

by Aurametrix team in Aurametrix Blog

Eyeglasses are almost as old as the civilization itself. They have not changed much since Benjamin Franklin's bifocals in the 18th century. Nor were they made obsolete by laser surgery and contacts. Still, eyeglass technology leaves much to be desired. But new technologies are unfolding before our eyes. ... Read more »

Pregnancy exposure to SSRIs and offspring autism risk: debate continues

by Paul Whiteley in Questioning Answers

"It remains unclear whether the association between first trimester SSRI [selective serotonin reuptake inhibitor] exposure and child autism that was present in the case-control studies even after adjustment for MMI [maternal mental illness] is a true association or a product of residual confounding."So said the results of the systematic review and meta-analysis undertaken by Hilary Brown and colleagues [1] looking at a potentially important association between pregnancy use of a class ........

Scientific reliability and the role of theory

by Multiple Authors in EPPI-Centre blog

The replication crisis, publication bias, p-hacking, harking, bad incentives, undesirable pressures and probably other factors all contribute to diminish the trustworthiness of published research, with obvious implications for research synthesis. Sergio Graziosi asks whether demanding simple theoretical clarity might be part of the solution.

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........

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........

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." Relying on data derived from The Avon Longitudinal Study of Parents and Children (ALSPAC) (so........ Read more »

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"

by Paul Whiteley in Questioning Answers

"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........

"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........

"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." ........
