Fatty acids and autism meta-analysed yet again (with a different result?)

by Paul Whiteley in Questioning Answers

OK I'm a little confused right now.Not so long ago I talked about the paper from Horvath and colleagues [1] (see here) concluding that "the limited data currently available suggest that ω-3 FA [omega-3 fatty acid] supplementation does not enhance the performance of children with ASD [autism spectrum disorder]." Such a conclusion was based on the application of a systematic review and meta-analysis of the available peer-reviewed literature up to August 2016.Now however, another sy........ Read more »

Autoimmune disease(s) and ADHD: birds of a feather?

by Paul Whiteley in Questioning Answers

"A personal history and a maternal history of autoimmune disease were associated with an increased risk of ADHD [attention-deficit hyperactivity disorder]. The previously reported association between type 1 diabetes and ADHD was confirmed. In addition, specific parental autoimmune diseases were associated with ADHD in offspring."So said the study results published by Nielsen and colleagues [1] including "a study population of 983,680 individuals followed from 1995 to 2012." Reliant once aga........ Read more »

Emotional Intelligence and the Physician

by William Yates, M.D. in Brain Posts

Emotional intelligence (EI) is characterized by the ability to recognize emotional states in self and in others.This emotional recognition may be helpful in guiding behavior and in improving interpersonal relationships.It seems logical on a face validity level to assume that higher levels of EI would be good in the selection of students for medical school.However, there are few studies assessing EI in physicians. There are fewer studies that examine whether EI influences physician behavior, pati........ Read more »

The Incredible Lesion-Proof Brain?

by Neuroskeptic in Neuroskeptic_Discover

How much damage can the brain take and still function normally? In a new paper, A Lesion-Proof Brain?, Argentinian researchers Adolfo M. García et al. describe the striking case of a woman who shows no apparent deficits despite widespread brain damage.



The patient, "CG", is 44 years old and was previously healthy until a series of strokes lesioned large parts of her brain, as shown below.

García et al. say that the damage included "extensive compromise of the right fronto-temporo-parie... Read more »

CHL1 Hypermethylation in Breast Cancer

by Esperanza Martín Sánchez in EpiBeat

Breast cancer (BC) is the most common cancer among women and one of the leading causes of cancer-related deaths worldwide (1-3). It is a clinically heterogeneous disease, with at least 5 different subtypes (4) and quite variable prognosis, even within a subtype. In spite of early detection programmes, unfortunately 20-30% of early stage cases will eventually experience recurrence and develop distant metastasis. However, currently, there is no acceptable method for monitoring patients who are lik........ Read more »

The extra-intestinal effects of coeliac disease autoimmunity?

"In 3.5-year-old children, CDA [coeliac disease autoimmunity] is associated with increased reports of child depression and anxiety, aggressive behavior, and sleep problems when mothers are unaware of their child’s CDA status."So said the findings reported by Laura Smith and colleagues [1] (open-access available here) adding to an emerging body of peer-reviewed research suggesting that the archetypal 'gluten is the baddie' autoimmune condition known as coeliac disease might, when not manag........

Internationalization as an indicator of journal performance in Brazil: the case of Psychology

by SciELO in SciELO in Perspective

The path to strengthening scientific publications almost always goes through internationalization. Publishing in English, however, is not enough to reach a truly global audience and indices comparable to the most prestigious journals. A study on the degree of internationalization of Brazilian psychology journals shows how to walk this path. … Read More →... Read more »

Solar Science with the Atacama Large Millimeter/Submillimeter Array — A New View of Our Sun by S. Wedemeyer

by CESRA in Solar Radio Science

The Atacama Large Millimeter/submillimeter Array (ALMA), which consists of 66 antennas placed on the Chajnantor plateau in the Chilean Andes, has already produced impressive results for a large range of astronomical objects. Regular observations of the Sun have been carried out for the first time in December 2016 and exciting results can be expected soon. ALMA combines high spatial, temporal, and spectral resolution with the diagnostic advantages of radiation at [...]... Read more »

Nonlinear effects in shallow water waves

by Mirjam Sophia Glessmer in Adventures in Oceanography and Teaching

I recently googled for something related to the shape of waves and came across a photo of a wave that caught my eye, and it took me to a journey that lead to the article “nonlinear shallow ocean wave soliton interactions on flat beaches” by Ablowitz and Baldwin (2012). What’s discussed in that article is that while…... Read more »

Depression in parents of children with autism

"Mothers (OR 2.95, 95% CI 2.81-3.09) and fathers (OR 2.41, 95% CI 2.25-2.58) of children with ASD [autism spectrum disorder] were more likely to have a diagnosis of depression than parents of children without ASD."The paper by Cohrs and Leslie [1] is probably not going to win any awards for novelty when it comes to their findings that: "Autism Spectrum Disorder (ASD) in children can have secondary effects on the child's parents." It does however represent another important piece of evidence........ Read more »

Earliest Brain Changes in Alzheimer's Disease

Amyloid brain plaques are well-known pathological changes associated with Alzheimer's disease. Changes preceding amyloid plaque build up are less well studied and understood. Some of this relates to limitations to current imaging technology.Klementieva and colleagues from Sweden and Spain recently published an important reserach topic in this area.Their studied used a rat model of Alzheimer's disease and imaging techniques that included infrared microspectroscopy and gel electrophoresis.The........

Mitochondria support for mitochondrial activity in [some] autism

Spontaneous Pneumothorax and air travel in BHD Syndrome

by Joana Guedes in BHD Research Blog

Previous studies show that BHD syndrome causes spontaneous pneumothorax (SP) in 24-38% of patients, with a recurrence rate of up to 75% (Toro et al., 2007; Toro et al., 2008; Houweling et al., 2011). A common preventative strategy used following an initial SP in patients with BHD is pleurodesis, however, its efficacy in preventing recurrent episodes is not well known. Due to the pressure changes during air travel, cystic air spaces expand and compress in the thorax possibly leading to cyst ruptu........ Read more »
