Food selectivity is a common feeding problem among autistic children. The objective of this qualitative study was to explore the impact of selective eating on key social domains-with family, peers, and in other social situations-of transition-age autistic youth who self-identified as being food selective. Interviews were conducted with 20 autistic youth ages 18-23 years. Data were analyzed using descriptive and thematic coding. Participants had developed a range of strategies to cope with their food selectivity, and although some expressed concerns, they did not feel that it had a major impact on social situations. A responsive approach to supporting such youth would likely involve recognizing the effort and skills that the youth have already developed around this issue.Light-adapted (LA) electroretinograms (ERGs) from 90 individuals with autism spectrum disorder (ASD), mean age (13.0 ± 4.2), were compared to 87 control subjects, mean age (13.8 ± 4.8). LA-ERGs were produced by a random series of nine different Troland based, full-field flash strengths and the ISCEV standard flash at 2/s on a 30 cd m-2 white background. A random effects mixed model analysis showed the ASD group had smaller b- and a-wave amplitudes at high flash strengths (p  less then  .001) and slower b-wave peak times (p  less then  .001). Photopic hill models showed the peaks of the component Gaussian (p = .035) and logistic functions (p = .014) differed significantly between groups. Retinal neurophysiology assessed by LA-ERG provides insight into neural development in ASD.This is the first longitudinal study to quantitatively evaluate changes in social network structure (SNS) and perceived social support (PSS) amongst first-year students on the autism spectrum (n = 21) and typically developing (TD; n = 182) students transitioning to university. The relative impact of changes in SNS/PSS, students' social anxiety and autistic traits, on first-year university transition outcomes were also examined. Both groups gained friends over time who provided better support quantity and quality during first year of university. Social anxiety showed long-term differential negative impact on students on the autism spectrum and TD students' academic, social and personal/emotional adjustments, and institutional attachment, suggesting stakeholders should focus on delivering interventions to reduce social anxiety to improve university transition outcomes.This study assessed the relationships between maternal systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) and risk for autism spectrum disorders (ASDs) in offspring. Seven observational studies, including 25,005 ASD cases and 4,543,321 participants, were included for meta-analysis. Pooled results by using random-effects models suggested that maternal RA was associated with an increased risk for ASDs [odds ratio (OR) 1.39, 95% confidence interval (CI) 1.16-1.67], while maternal SLE was associated with an increased risk for ASDs only in western population (OR 1.91, 95% CI 1.02-3.57). Further study is warranted to confirm these results.This study investigated rates of suicidal ideation (SI) and suicidal and/or self-injurious behaviour (SSIB) reported by parents on the Child Behavior Checklist for 178 children with ASD over four annual assessments (ages 7-11 years). Analyses examined the frequency and persistence of SI and SSIB, and the association of SI and SSIB at any time point with child characteristics and internalizing and externalizing problems at age 7. SI occurred in 9.6% of children and was associated with fewer ASD symptoms and better adaptive functioning at age 7. SSIB occurred in 14.6% and was associated with poorer adaptive functioning and more externalizing behaviour at age 7. Internalizing problems were not associated with SI or SSIB at any time point. SI and SSIB rarely co-occurred (4%).Doxorubicin is a commonly used chemotherapeutic agent for the treatment of a range of cancers, but despite its success in improving cancer survival rates, doxorubicin is cardiotoxic and can lead to congestive heart failure. Therapeutic options for this patient group are limited to standard heart failure medications with the only drug specific for doxorubicin cardiotoxicity to reach FDA approval being dexrazoxane, an iron-chelating agent targeting oxidative stress. However, dexrazoxane has failed to live up to its expectations from preclinical studies while also bringing up concerns about its safety. Despite decades of research, the molecular mechanisms of doxorubicin cardiotoxicity are still poorly understood and oxidative stress is no longer considered to be the sole evil. Mitochondrial impairment, increased apoptosis, dysregulated autophagy and increased fibrosis have also been shown to be crucial players in doxorubicin cardiotoxicity. These cellular processes are all linked by one highly conserved intracellular kinase adenosine monophosphate-activated protein kinase (AMPK). AMPK regulates mitochondrial biogenesis via PGC1α signalling, increases oxidative mitochondrial metabolism, decreases apoptosis through inhibition of mTOR signalling, increases autophagy through ULK1 and decreases fibrosis through inhibition of TGFβ signalling. AMPK therefore sits at the control point of many mechanisms shown to be involved in doxorubicin cardiotoxicity and cardiac AMPK signalling itself has been shown to be impaired by doxorubicin. mTOR phosphorylation In this review, we introduce different agents known to activate AMPK (metformin, statins, resveratrol, thiazolidinediones, AICAR, specific AMPK activators) as well as exercise and dietary restriction, and we discuss the existing evidence for their potential role in cardioprotection from doxorubicin cardiotoxicity.PURPOSE Although physical inactivity (PI) is universally considered a major risk factor for cardiovascular disorders, no previous study has investigated its putative contribution on the societal and healthcare burden of ischemic heart disease (IHD). Therefore, we aimed to provide an objective assessment of the worldwide epidemiology of PI-related IHD. METHODS An electronic search was performed in the Global Health Data Exchange (GHDx) registry, a large database of health-related data, for assessing the worldwide epidemiology of PI-related IHD. RESULTS The current burden of PI-related disability-adjusted life years (DALYs) and deaths caused by IHD is 9.1% (15.42 out of 170.27 million DALYs) and 9.9% (5.46 out of 55.14 million deaths), respectively. Women have a ~ 14% higher risk of both PI-related DALYs and mortality. The impact of PI on IHD remains stable around 7% up to the middle age, then gradually increases in parallel with aging, up to over 11%. A ~ 20% higher risk of PI-related DALYs and mortality caused by IHD can be found in countries with middle-to-high socio-demographic index (SDI) compared with countries with lower SDIs.
