Bipolar disorder and the autism spectrum continued

by Paul Whiteley in Questioning Answers

In a previous post on this blog I talked about an important paper by Vannucchi and colleagues [1] summarising the state of the peer-reviewed research (up to 2014) on bipolar disorder and Asperger syndrome (AS). Today, I'm adding to the conversation on this important topic by introducing two papers to the discussions: the first by Xenia Borue and colleagues [2] and the second by Ahmad Abu-Akel and colleagues [3] covering the longitudinal course of bipolar disorder (BD) in rela........

Your BMI might affect your brain function

by Dr. Jekyll in Lunatic Laboratories

There are plenty of reasons it's important to maintain a healthy weight, and now you can add one more to the list: It may be good for your brain. Researchers have found that having a higher body mass index, or BMI, can negatively impact cognitive functioning in older adults.

Red meat and organs may pose a significant health hazard

by Dr. Jekyll in Lunatic Laboratories

Neu5Gc, a non-human sialic acid sugar molecule common in red meat that increases the risk of tumor formation in humans, is also prevalent in pig organs, with concentrations increasing as the organs are cooked, a study has found. The research suggests that Neu5Gc may pose a significant health hazard among those who regularly consume organ meats from pigs.

Does Effect Size Matter for fMRI?

by Neuroskeptic in Neuroskeptic_Discover

fMRI researchers should care about (and report) the size of the effects that they study, according to a new Neuroimage paper from NIMH researchers Gang Chen and colleagues. It's called Is the statistic value all we should care about in neuroimaging?. The authors include Robert W. Cox, creator of the popular fMRI analysis software AFNI.



Chen et al. explain the purpose of their paper:
Here we address an important issue that has been embedded within the neuroimaging community for a long tim... Read more »

Language and motor skills: preschool predictors of academic achievement in autism

by Paul Whiteley in Questioning Answers

A fairly quick post for your reading delight today as I bring the paper by Miller and colleagues [1] to your attention suggesting that: "Early intervention targeting language and motor skills may improve later achievement in this population."'This population' referred to a small cohort (N=26) of children diagnosed with an autism spectrum disorder (ASD) who were examined "at the approximate ages of two, four, and ten" years with regards to their academic achievement and the variables that might b........

A new view of the immune system

by Dr. Jekyll in Lunatic Laboratories

Pathogen epitopes are fragments of bacterial or viral proteins. Attached to the surface structure of cells, they prompt the body's immune system to mount a response against foreign substances. Researchers have determined that nearly a third of all existing human epitopes consist of two different fragments. Known as 'spliced epitopes', these types of epitopes have long been regarded as rare. The fact that they are so highly prevalent might, among other things, explain why the immun........ Read more »

Chest CT in patients with spontaneous pneumothorax is cost-effective

by Joana Guedes in BHD Research Blog

Patients that present with a spontaneous pneumothorax (SP) without a known medical history of lung disease are usually diagnosed as primary spontaneous pneumothorax - a pneumothorax that occurs without underlying diseases. However, underlying diffuse cystic lung diseases such as Birt-Hogg-Dube syndrome (BHD), lymphangioleiomyomatosis (LAM) and pulmonary Langerhans cell histiocytosis (PLCH) may have a spontaneous pneumothorax as their first symptom. In their new study, Gupta et al. (2016) evaluat........ Read more »

One more time: asthma and autism

by Paul Whiteley in Questioning Answers

I'm actually getting a little bored of talking about the various peer-reviewed research looking at a possible connection between asthma and autism on this blog. It's not that it isn't an interesting topic but rather that the data is coming in thick and fast suggesting that behaviour and physiology are not completely separate anymore.I did however want to direct you to the paper by Alessandro Tonacci and colleagues [1] who, following a systematic review "according to the PRISMA guidelines" s........

Oligodendrocyte selectively myelinates a particular set of axons in the white matter

by Dr. Jekyll in Lunatic Laboratories

There are three kinds of glial cells in the brain, oligodendrocyte, astrocyte and microglia. Oligodendrocytes myelinate neuronal axons to increase conduction velocity of neuronal impulses. A Japanese research team found a characteristic feature of oligodendrocytes that selectively myelinate a particular set of neuronal axons.

Is the reproducibility crisis exacerbated by pre-publication peer review?

"Folinic acid improves communication in childhood autism"

A quote to begin: "... in this small trial of children with non-syndromic ASD [autism spectrum disorder] and language impairment, treatment with high-dose folinic acid for 12 weeks resulted in improvement in verbal communication as compared with placebo, particularly in those participants who were positive for FRAAs [folate receptor-α autoantibody]."Those were the findings reported by Richard Frye and colleagues [1] (open-access) continuing a research theme from this group l........

A Windstorm is a Reminder of Disaster Preparation for Pets

by CAPB in Companion Animal Psychology Blog

The best time to start disaster preparation for your pet is now.Recently, like many people in this part of the world, we heard there was a big storm on the way. The third of three windstorms was said to be the most powerful. Since we live in an area with many beautiful trees and the power lines are above ground, it does not take much to knock out the power.In the end, we were lucky. The storm was not as strong as predicted, and it changed track and went further north. But it’s a reminder that ........ Read more »

Divided [North] America: We are (still) divided on climate change 

by Doug Keene in The Jury Room

Our scientists are not divided but we the people are very divided on the issue of climate change. You would think that when 97% of scientists agree the global weather patterns (aka “climate change”) are changing (aka “warming”) that Americans would give up and just say “okay, yeah, it’s happening”. But if you think that, […]

Paracetamol for fever 'associated' with autism?

by Paul Whiteley in Questioning Answers

"In this study, we again show that acetaminophen use is associated with ASD [autism spectrum disorder]."That was one of the results reported by Stephen Schultz & Georgianna Gould [1] (open-access available here) as part of their survey of the US "National Database for Autism Research (NDAR) of the National Institute of Mental Health (NIMH)" looking at "whether ASD is associated with acetaminophen use." Acetaminophen by the way, is another name for paracetamol, the over-the-counter ........ Read more »

Autophagy in CSFV and ZIKV infected cells: persistence versus neurodegenerative disease

by thelonevirologist in Virology Tidbits

Zika Virus (ZIKV) was first isolated in 1947 from a sentinel monkey in Uganda and associated with human infection in 1954 when neutralizing antibodies were detected in the sera of residents in India, with antibodies also being found in residents from various African countries. ZIKV is mosquitoe-borne Flavivirus that is predominantly transmitted via Aedes Agypti, although sexual transmission (female to male, male to female, male to male) and transmission via blood transfusion has also been report........
