Autism prevalence in the Somali population in Minneapolis continued

by Paul Whiteley in Questioning Answers

A very quick post today to direct you to the paper by Amy Hewitt and colleagues [1] who seem to have finally published their findings on autism prevalence in the Somali population in Minneapolis in the peer-reviewed domain. I had previously covered their report on this blog (see here) and the suggestion that: "Somali (1 in 32) and White (1 in 36) children were about equally likely to be identified with ASD [autism spectrum disorder], but more likely to be identified with ASD than Black and ........

NAC for 'social impairment' in youth with autism... probably not

by Paul Whiteley in Questioning Answers

"The results of this trial indicate that NAC [N-acetylcysteine]  treatment was well tolerated, had the expected effect of boosting GSH [glutathione] production, but had no significant impact on social impairment in youth with ASD [autism spectrum disorder]."So said the results reported by Logan Wink and colleagues [1] (open-access) who, continuing an autism research theme, looked at whether this important L-cysteine prodrug might have more to give when it comes to a........

The developmental correlates of asthma (again)

by Paul Whiteley in Questioning Answers

Can I just get it out of the way? May the 4th be with you.OK. The results from Mark Strom & Jonathan Silverberg [1] caught my eye recently and further evidence of a 'correlation' between asthma and developmental and/or behavioural outcomes. This time around it was "caregiver-reported speech disorders in US children" and how the appearance of asthma, hay fever and/or food allergy might show some important relationships with something like speech disorder. This follows other, similar work from........ Read more »

Machine learning applied to autism screening going big time?

by Paul Whiteley in Questioning Answers

Machine learning, when machines, er.. learn, is of growing interest to the autism research field. The names Wall and Duda have filled quite a few posts on this blog (see here and see here for example) on this topic and their suggesting that applying machine learning algorithms to something like autism screening and detection could cut down on time taken and resources used.As per the publication of the paper by Daniel Bone and colleagues [1] it appears that others working in autism research are a........

Origin of synaptic pruning process linked to learning, autism and schizophrenia identified

by Dr. Jekyll in Lunatic Laboratories

Vaccines don't cause autism, but because the brain is so complex, we still don't know how much of it works so figuring out the real causes (as in more than one) of autism has been slow going. Well, researchers have identified a brain receptor that appears to initiate adolescent synaptic pruning, a process believed necessary for learning, but in this case it is one that appears to go awry in both autism and schizophrenia....

On defining chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME)

by Paul Whiteley in Questioning Answers

Most people who know a little bit about chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) will probably understand the potential importance of the findings reported by Leonard Jason and colleagues [1] (open-access available here). Suggesting that there may be "four groupings of patients" when it comes to how we "name and define the illnesses", this research group who surveyed over 500 people "in the United States, Great Britain, and Norway" report on one of the biggest challenge........

Salts in the brain control our sleep-wake cycle

by Dr. Jekyll in Lunatic Laboratories

Insomnia, fun fact those of us who have served or are serving in the military have a much higher incidence of sleep problems. So if you are like me and have ever been prescribed something to help you sleep, you know that there are some unwanted side effects. For instance the time I lost memory of a whole day of interacting with people to the ambien I had taken the night before, not fun. Thankfully Danish researchers found that the level of salts in the brain plays a critical role in whether we a........ Read more »

The 'anti-neuroinflammatory activity' of oxytocin

by Paul Whiteley in Questioning Answers

Whilst the package inserts of the various drugs that modern medicine has at its disposal provides important information on potential mode of action, there is a growing realisation that drugs generally have quite a few more molecular targets than are perhaps listed. Take for example the quite commonly used (in some parts of the world anyway) compound called melatonin  that in some instances can provide almost miraculous relief when it comes to sleeping issues under certain circumstances. A d........ Read more »

Signatures of Mutational Processes Extracted from the Mutational Catalogs of 21 Breast Cancer Genomes. Credit:http://dx.doi.org/10.1016/j.celrep.2012.12.008Cancer is the second leading cause of death worldwide, with approximately 14 million new cases and 8.2 million cancer related deaths each year (Source: WHO).

Organophosphate exposure and ADHD?

"Children with higher urinary DMP [dimethylphosphate] concentrations may have a twofold to threefold increased risk of being diagnosed with ADHD [attention-deficit hyperactivity disorder]."So said the results presented in the paper by Yu and colleagues [1] who looking at "97 doctor-diagnosed ADHD cases and 110 non-ADHD controls who were 4-15 years of age" examined urine and blood samples for various factors including "biomarkers of OP [organophosphate] pesticide exposure."

What parents of children with autism expect from their child's therapists

by Paul Whiteley in Questioning Answers

"Parents ultimately wanted therapists to produce positive outcomes for their children and were willing to sacrifice other desired qualities, as long as the therapy program was effective."and"The SLPs [Speech-Language Pathologists] expressed strong support for evidence-based practice (EBP) and indicated that they thought parents expected their children would be provided with evidence-based interventions."Those quotes come from two papers recently published in the same journal; the first........

Addiction, it’s in your genes… maybe

by Dr. Jekyll in Lunatic Laboratories

Why does one person who tries cocaine get addicted, while another might use it and then leave it alone? Why do some people who kick a drug habit manage to stay clean, while others relapse? And why do some families seem more prone to addiction than others? According to a new study, the road to answering these questions may have a lot to do with specific genetic factors that vary from individual to individual.

Food to Restore a Heart

by Aurametrix team in Health Technologies

We know that diet, exercise and low-stress life will keep the heart healthy. But sometimes things happen that are beyond our control. Thanks to more coordinated, faster emergency response and improved treatment, heart attacks aren't as deadly as they used to be. But survivors still face a substantial risk of further cardiovascular events. How to restore after a heart attack and prevent another one? What to do besides obvious things such as taking medications, reducing stress, calories, avoidin........ Read more »

The A Word: the science behind...

by Paul Whiteley in Questioning Answers

The A WordI'm not typically inclined to talk about TV programmes on this blog (well, not usually) but today I'm making an exception based on the conclusion of the BBC drama series 'The A Word' last evening.For those who might not know, this [fictional] series charts the ups and downs of a family living in the Lake District whose lives are in one way or another touched by autism as a function of a 5-year old boy diagnosed with the condition. The show had a notable addition to the cast with a very........ Read more »

Bacterial origin and transferability of depression?

by Paul Whiteley in Questioning Answers

The paper by Zheng and colleagues [1] caught my eye recently and the interesting ideas that "dysbiosis of the gut microbiome may have a causal role in the development of depressive-like behaviors" and "transplantation of GF [germ-free] mice with ‘depression microbiota’ derived from MDD [major depressive disorder] patients resulted in depression-like behaviors compared with colonization with ‘healthy microbiota’ derived from healthy control individuals."Bearing in........

Liver Regeneration in Living Donors

by Cristy at Living Donor 101 in Living Donors Are People Too

The authors examined the liver function and liver volume of 91 right liver lobe donors. Within a year of donating, 96% had regained full liver function but only 85% had full pre-donation liver volume.   Unfortunately, these results say nothing about the long term risk of scarring (cirrhosis) or otherwise.   Duclos J, Bhangui P, …
