The correlates of regressive autism

by Paul Whiteley in Questioning Answers

"A more homogeneous subgroup with regression between 18 and 36 months (n = 48) had higher rates of intellectual disability, epilepsy, and special education, more socially restrictive educational settings, and more severe ASD [autism spectrum disorder] communication deficits and schizophrenia spectrum symptoms than non-regressed youth (n = 136)."So said the findings reported by Kenneth Gadow and colleagues [1] taking on one of the more important issues in relation to autism: dev........

Physical activity levels and autism (again)

by Paul Whiteley in Questioning Answers

"Adolescents with ASD [autism spectrum disorder] spent less time in MVPA [moderate and vigorous physical activity] compared to TD [typically developing] adolescents (29 min/day vs. 50 min/day, p < 0.001) and fewer met the Physical Activity Guidelines for Americans (14 vs. 29%, p > 0.05)."So said the study results published by Heidi Stanish and colleagues [1] adding yet more to another growth autism research area - physical activity and exercise - ........

Vitamin D supplementation and self-perceived fatigue

by Paul Whiteley in Questioning Answers

"Vitamin D treatment significantly improved fatigue in otherwise healthy persons with vitamin D deficiency."Supplementation details, described in the paper by Albina Nowak and colleagues [1] (open-access available here), were a single dose of 100,000 IU [international units] of vitamin D or a placebo (mannitol) administered to 120 adult participants who presented with "fatigue and vitamin D deficiency (serum 25(OH)D < 20 μg/L)." This was a double-blind trial and self-perceived fatigue ........ Read more »

Autism-like traits and/or autism elevated in psychosis

by Paul Whiteley in Questioning Answers

"Rates of ASD [autism spectrum disorder] and ASD traits are elevated in a psychosis population."The paper by Debbie Kincaid and colleagues [1] provides yet more [short] blogging material pertinent to the increasing interest in how psychosis may be yet another comorbidity over-represented when it comes to autism (see here) and vice-versa. I know this is another topic that has to be treated with some caution in terms of concepts like stigma but more discussions - science discussions........ Read more »

“World’s toughest bacterium” - Deinococcus radiodurans

by Usman Paracha in SayPeople

The bacterium, Deinococcus radiodurans, is thought to be discovered as a contaminant in radiation-sterilized cans in 1960s. The name of the bacterium comes from the Ancient Greek, i.e. deinos and kokkos meaning “terrible grain/berry”, and the Latin language, i.e. radius and durare, meaning “radiation surviving”. The bacterium is also known as Conan the Bacterium.

Deinococcus radiodurans is a comparatively larger bacterium having spherical shape. It is a red-pigmented b........ Read more »

No significant difference in circulating cytokines in autism vs controls?

by Paul Whiteley in Questioning Answers

"As compared with 54 typically developing controls, we found no evidence of differences in the blood profile of immune mediators supportive of active systemic inflammation mechanisms in participants with autism."That was the unexpected research bottom-line published by Carlos Pardo and colleagues [1] (open-access) examining whether various immune-related chemicals - "cytokines, chemokines, or growth factors in serum and cerebrospinal fluid" - might be linked to autism following longitudinal........

Nutrient-dependent FNIP degradation regulates FLCN localization and promotes renal cancer progression

by Joana Guedes in BHD Research Blog

Birt-Hogg-Dubé (BHD) syndrome is a rare disorder caused by mutations in FLCN and associated with increased risk of kidney cancer. It has been shown that FLCN-interacting protein 1 and 2 (FNIP1 and FNIP2) double knockout mice, like the FLCN knockout mice, develop renal carcinoma (Hasumi et al., 2015). However, the molecular mechanisms linking FNIP and FLCN remain unknown. In their new study, Nagashima et al. (2016) show that FNIP2 undergoes proteasome-dependent degradation via β-TRCP ........

Exercise as an intervention for anxiety?

by Paul Whiteley in Questioning Answers

"Our data suggest that exercise is more effective than control at reducing anxiety symptoms."So said the meta-analysis published by Brendan Stubbs and colleagues [1] who surveyed the peer-reviewed literature "investigating the benefits of exercise compared to usual treatment or control conditions in people with an anxiety and/or stress-related disorders." From the 6 randomised, controlled trials found "from inception until December 2015" exercise (various types of exercise regime) did seem to ha........ Read more »

Acute coronary syndrome on Friday the 13th: a case for re-organising services?

by Rogue Medic in Rogue Medic

"However, patients admitted on five day/number combinations were 20-30% more likely to survive at 13 years. These findings could be explained by subgroup analysis inflation of the type I error, although supernatural causes merit further investigation.[1]"

No. Supernatural causes do not merit further investigation, at least, not based on anything in this paper.

The authors used Friday the 13th as their "normal" date for comparison with every other date, but the outcomes ........ Read more »

On autism risk and immigrant status

by Paul Whiteley in Questioning Answers

"Fifteen studies suggest a higher prevalence rate of ASDs [autism spectrum disorder] among children of immigrants in comparison to native children."Those fifteen studies formed a large part of the seventeen studies included in the review by Rafal Kawa and colleagues [1] who set out to look at the collected peer-reviewed literature on the topic of the "prevalence and risk for ASD in Europe among immigrants and ethnic minorities." Carried out as part of a European Union (EU) initiative t........ Read more »

DNA Methylation in the Placenta: accelerated aging in pregnancy complications

by Tina Bianco-Miotto in EpiBeat

The placenta is a unique organ as it is an extra-embryonic tissue primarily regulated by the fetal genome and shared between mother and fetus. However, it is a transient organ that is only needed throughout pregnancy and gestation and then is discarded after delivery. The essential role of the placenta in pregnancy is unquestionable but, surprisingly, as highlighted by the NIH NICHD Human Placenta Project (https://www.nichd.nih.gov/research/HPP/Pages/default.aspx), it is the human organ we know ........

H255Y and K508R missense mutations in FLCN promote kidney neoplasia

by Joana Guedes in BHD Research Blog

The germline FLCN missense mutations H255Y (Hasumi et al., 2009) and K508R (Toro et al., 2008) have been identified in patients with bilateral multifocal (BMF) kidney tumours and other clinical symptoms of Birt-Hogg-Dube (BHD) syndrome, or with BMF kidney tumours as the only manifestation. Building on their previous work identifying the H255Y mutation in human BHD kidney tumour, Hasumi et al. (2016) investigated whether these mutations have an impact on FLCN function. The authors evaluated the F........ Read more »

T. gondii and OCD?

by Paul Whiteley in Questioning Answers

It's been a while since I've talked about Toxoplasma gondii on this blog; the parasite that more than most, has been linked with all-manner of different psychiatric labels (see here for example). Although still the topic of some discussion, I'm swayed towards the possibility that there may be some important *associations* to be seen when it comes to this survivor and human behaviour(s) outside of just making rats attracted to cat urine (see here) to improve reproduction chances.Indeed, in t........

ADHD and vitamin levels

It is important to identify these patients in dietary intervention trials of ADHD."So said the study findings reported by Elisabeth Toverud Landaas and colleagues [1] (open-access) providing some potentially important data on how nutritional factors might int........
