However, no information on potential racial and ethnic disparities in ASD diagnosis can be found in the literature. Most recently, the possible structural racism and health inequities have been a concern for the public and policy makers.

Response: Over twenty years ago we identified the existence of a non-genetic form of inheritance through analysis of environmentally induced epigenetic transgenerational inheritance of disease, now well established in a number of species including humans.  I was giving a talk on this topic at a meeting in Spain.   This study was initiated following the scientific meeting in Spain with an in vitro fertilization clinical group that said they had access to sperm from males with and without autistic children.  It took several years to collect and characterize the samples, and find financial support for the study.  Once this was done then we did the molecular analysis to see if the sperm from fathers with autistic children had epigenetic, DNA methylation alterations, that associated with them having offspring with autism.

Response: Deletions on chromosome 2p16.3, involving deletion of the NEUREXIN1 gene, dramatically increase the risk of developing a wide range of neurodevelopmental disorders including autism, Tourette’s syndrome and schizophrenia. We don’t fully understand the mechanisms involved. In our study we wanted to understand how the genetic deletion impacts on brain function and the ability of brain regions to communicate with one another, as these are known to be impaired in these neurodevelopmental disorders. We also wanted to determine how the genetic deletion impacts on the function of neurotransmitter systems involved in these disorders, and whether drugs targeting these neurotransmitter systems could restore some of the deficits in brain function seen.

Response: One of the most common questions we get from parents with a child with autism is, "what is the likelihood of having a second or third child with autism, and what is the chance others in our family will have kids with autism?". To help provide answers to these questions, we started the infant (or baby) siblings study ten years ago. Families having an older sibling with a diagnosis of autism were invited to enroll their next born for assessment and following to see if they also developed autism, and what the likelihood of that happening was. Biological samples like blood, and DNA from blood, were also collected and tested.

MedicalResearch.com Interview with: Tianyang Zhang, MSc Centre for Psychiatry Research, Department of Clinical Neuroscience Stockholm Health Care Services, Stockholm County Council Department of Medical Epidemiology and Biostatistics Karolinska Institutet Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: We know that births by caesarean delivery are linked to several negative health outcomes in the children, such as obesity, asthma, allergy, and type 1 diabetes. However, the association between c-section and neurodevelopmental and psychiatric disorders has been less studied. In addition, it is unclear whether the extent of this association is different if a caesarean section is performed planned in advance or urgently due to medical reasons during a delivery.

MedicalResearch.com Interview with: [caption id="attachment_48157" align="alignleft" width="160"]Beth Hoffman, B.Sc., graduate studentUniversity of Pittsburgh Graduate School of Public HealthResearch Assistant,University of Pittsburgh Center for Research on Media, Technology and Health Beth Hoffman[/caption] Beth Hoffman, B.Sc., graduate student University of Pittsburgh Graduate School of Public Health Research Assistant, University of Pittsburgh Center for Research on Media, Technology and Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Vaccine refusal is a public health crisis - low vaccination rates are leading to outbreaks of deadly vaccine-preventable diseases. In 2017, Kids Plus Pediatrics, a Pittsburgh-based pediatric practice, posted a video on its Facebook pagef eaturing its practitioners encouraging HPV vaccination to prevent cancer. Nearly a month after the video posted, it caught the attention of multiple anti-vaccination groups and, in an eight-day period, garnered thousands of anti-vaccination comments. Our team analyzed the profiles of a randomly selected sample of 197 commenters in the hopes that this crisis may be stemmed if we can better understand and communicate with vaccine-hesitant parents. We determined that, although Kids Plus Pediatrics is an independent practice caring for patients in the Pittsburgh region, the commenters in the sample were spread across 36 states and eight countries. By delving into the messages that each commenter had publicly posted in the previous two years, we also found that they clustered into four distinct subgroups:
  • “trust,” which emphasized suspicion of the scientific community and concerns about personal liberty;
  • “alternatives,” which focused on chemicals in vaccines and the use of homeopathic remedies instead of vaccination;
  • “safety,” which focused on perceived risks and concerns about vaccination being immoral; and
  • “conspiracy,” which suggested that the government and other entities hide information that this subgroup believes to be facts, including that the polio virus does not exist.

Wall, PhDAssociate ProfessorDepartments of Pediatrics, Psychiatry (by courtesy) and Biomedical Data ScienceStanford University Dr. Wall[/caption] Dennis P. Wall, PhD Associate Professor Departments of Pediatrics, Psychiatry (by courtesy) and Biomedical Data Science Stanford University  MedicalResearch.com: What did we already know about the potential for apps and wearables to help kids with autism improve their social skills, and how do the current study findings add to our understanding? What’s new/surprising here and why does it matter for children and families?  Response: We have clinically tested apps/AI for diagnosis (e.g.  https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002705) in a number of studies. This RCT is a third phase of a phased approach to establish feasibility and engagement through in-lab and at-home codesign with families with children with autism. This stepwise process is quite important to bring a wearable form of therapy running AI into the homes in a way that is clinically effective. What’s new here, aside from being a first in the field, is the rigorous statistical approach we take with an intent-to-treat style of analysis. This approach ensures that the effect of the changes are adjusted to ensure that any significance observed is due to the treatment.  Thus, with this, it is surprising and encouraging to see an effect on the VABS socialization sub-scale. This supports the hypothesis that the intervention has a true treatment effect and increases the social acuity of the child. With it being a home format for intervention that can operate with or without a clinical practitioner, it increases options and can help bridge gaps in access to care, such as when on waiting lists or if the care process is inconsistent.

What are the main findings? Response: Autism is a lifelong condition, and challenges associated with autism persist from childhood into adulthood. Despite this, research and treatment have been largely dedicated to children. Because of that, we had very little understanding of what areas – what cognitive domains - are most severely impacted in adults with autism. Importantly, the lack of such information also limits treatment development in this area. What is known already is that adults with autism display deficits in social cognition (which refers to the role that cognitive processes play in our social interactions). Although our meta-analysis supported these theories, it also highlighted several other challenges in cognitive processing, such as deficits in processing speed and verbal learning and memory. And these impairments were observed in adults with autism without an overall intellectual disability.

What are the main findings? Response: This study evaluated within-diagnosis sibling recurrence and sibling cross-aggregation of ADHD and autism spectrum disorder among later-born siblings of diagnosed children. We specifically chose to include only families who had at least one subsequent child after the diagnosis of an older child because failing to do so could bias recurrence risk estimates. We found that, compared to later-born siblings of non-diagnosed children, later-born siblings of children with autism were more likely to be diagnosed with autism or with ADHD. Likewise, compared to later-born siblings of non-diagnosed children, later-born siblings of children with ADHD were more likely to be diagnosed with ADHD or with autism.

Ph.D. School Psychologist Lehigh University Dr. Barrett[/caption]   Charles Barrett. Ph.D. School Psychologist Loudon County Virginia Public Schools   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous studies have shown that Black children are more likely to receive ratings that are more indicative of displaying externalizing behavior difficulties, including Attention Deficit Hyperactivity Disorder (ADHD).  However, many of these studies included teachers as the informants. Consistent with most teachers in the United States, raters have typically been White females.  For this reason, it is unclear if these outcomes would exist if the rater and child shared the same racial/ethnic background. Additionally, most research in the United States that involved cross-cultural comparisons has used White and Hispanic boys.  Few empirical studies have examined differences between Black and White boys. The present study sought to address several limitations in the field.  Most notably, cross-cultural comparisons between Black and White boys were included instead of Hispanic and White children.  Next, maternal figures, rather than teachers, were included as the informants. The present study was developed using a similar methodology that examined Hispanic and White boys’ behavior from the perspective of Hispanic and White teachers (Dominguez de Ramirez & Shapiro, 2005). In sum, we sought to determine if there were differences in how Black and White maternal figures rated Black and White boys who were demonstrating the same level/type of behavior (i.e., sub-clinical levels of ADHD).  Notably, although the boys’ behaviors were the same, maternal ratings were not identical. Specifically, using the ADHD Rating Scale, Fourth Edition (ARS-4), Black mothers assigned higher ratings to both Black and White boys.

MedicalResearch.com Interview with: Michael Kogan, Ph.D. Director of the office of Epidemiology and Research Health Resources and Services Administration’s Maternal and Child Health Bureau MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a study led by the Health Resources and Services Administration’s Maternal and Child Health Bureau, along with researchers from the Centers from Disease Control and Prevention, Harvard, Drexel, and George Washington Universities.  We used the 2016 National Survey of Children’s Health, a nationally representative survey of over 50,000 children that examines the health and well-being of US children, to examine the prevalence, treatment, and health care experiences of children with Autism Spectrum Disorder (ASD). We found that 1 out of 40 children in the US were reported by their parents to have been diagnosed with Autism Spectrum Disorder.  We also found that children with ASD were significantly less likely to receive services like needed care coordination, referrals to other services, and mental health counseling – even compared to children with other emotional, behavioral or developmental disorders (EBDs).  Parents of children with ASD were also significantly more likely to report being usually or always frustrated in their attempts to get services, again compared to families of children with other EBDs. Finally, we looked at treatment patterns for children with ASD and found that 64% had received behavioral therapy in the year before the interview, and 27% had received medications to treat symptoms of irritability.

MedicalResearch.com Interview with: [caption id="attachment_46215" align="alignleft" width="149"]Michael Lombardo, PhD Assistant professor of Psychology the University of Cyprus  Dr. Lombardo[/caption] Michael Lombardo, PhD Assistant professor of Psychology the University of Cyprus  MedicalResearch.com: What is the background for this study? Response: Autism is a diagnostic label we give to children with difficulties in the areas of social-communication and restricted, repetitive stereotyped behaviors and interests. The diagnosis is made based on observations about behavior and is a consensus label, meaning that clinicians can show high degrees of agreement that a given set of behaviors is ‘autism’. But aside from the diagnostic label, there is a fair degree of heterogeneity within patients that have the diagnosis. One way in which patients are heterogeneous is with regard to early language development. Some toddlers with autism are minimally verbal, while at the other end, many toddlers with autism develop language typically. An important question to answer is whether that kind of difference in language development indicates a subtype with different underlying biology. To examine this question, we first split toddlers with autism into two subtypes defined by their language outcome at 4 years of age. Some toddlers were classified as poor language outcome, because their language performance was 1 standard deviation below typical norms. Other toddlers with autism had relatively good language outcome, as their language performance by 4 years of age was within 1 standard deviation of typical norms. We also measured the biology behind these two autism subtypes. First we used functional magnetic resonance imaging (fMRI), which is a non-invasive method to look at blood oxygenation response that changes according to a task. Blood oxygenation changes are an indirect measure of neural activity. We used fMRI during natural sleep at around 29 months of age while the toddlers were played language stimuli through headphones to elicit neural responses to speech. Second, we measured molecular aspects of biology, by taking blood samples, isolating leukocyte cells, and then quantifying gene expression for all protein coding genes in the genome, at around the same time as the fMRI scan.

What are the main findings?  Response: Aberrant brain connectivity is believed to be a robust neurobiological underpinning in individuals with autism spectrum disorder. To date, the majority of functional connectivity fMRI studies have focused on the strength of the relationship between coactivating regions of the brain during a resting state. An often-replicated finding suggests individuals with autism demonstrate increased short-range functional connectivity and decreased long-range functional connectivity. Our study focuses on the temporal domain of functional connectivity fMRI data acquired using long duration multiband, multiecho acquisitions. We used two different measurements of the temporal synchrony between brain regions to establish that, on average, individuals with autism exhibit prolonged functional connectivity in multiple regions associated with a diagnosis of the disorder. A number of these findings were then replicated in a large multisite dataset (Autism Brain Imaging Data Exchange). Additionally, we found a strong positive relationship between the duration of functional connectivity in multiple brain regions and symptoms relating to social dysfunction in individuals with autism suggesting that they may need to hang on to neural connections just a bit longer in order to process social queues and quickly changing novel sensory information.

Hicks, M.D.,Ph.D Department of Pediatrics Penn State College of Medicine Hershey, PA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Since autism has both genetic and environmental underpinnings, my colleagues and I suspected that transcriptional elements (e.g. regulatory RNA molecules) might be different in the saliva of children with autism compared to peers without autism. We used a non-biased approach to analyze saliva from 372 children, and allowed machine learning techniques to inform which RNA elements best predicted autism status. To our surprise, microbial RNA levels and human RNA levels were equally powerful in predicting which children had autism. This may be because some children with autism eat restricted diets, resist tooth brushing, or put foreign objects in their mouths. The end result was a panel of 32 RNAs (20 human and 12 bacterial) that identified autism with 87% accuracy. Interestingly, when we tested the panel in a completely separate set of 84 children (including children from a different geographic region) the accuracy remained 88%.

Response: Our paper explored the association between maternal use of medication during pregnancy and the rates of autism in a large cohort from Israel. This followed on from a number of earlier studies reporting that the use of certain medications - for example antidepressants - during pregnancy is associated with higher rates of autism in children. However, rather than test the effects of any particular drug, or a set of drugs aggregated based on maternal condition, our large dataset allowed us to group all medications prescribed to pregnant women based on their drug target, and in the subsequent analyses focus on over 50 groups that included drugs with neurotransmitter-relevant targets - for example agonists and antagonists of their receptors.

MedicalResearch.com Interview with: Dr. Marcus Smith PhD Reader in Sport and Exercise Physiology University of Chichester Co-founder, Clem Burke Drumming ProjectDr. Marcus Smith PhD Reader in Sport and Exercise Physiology University of Chichester Co-founder, Clem Burke Drumming Project MedicalResearch.com: What is the background for this study? Response: The research group first started to examine rock drumming from a scientific perspective in 1999 through collaboration with Clem Burke, drummer with the iconic band ‘Blondie’. In 2008 the Clem Burke Drumming Project (CBDP) was formed (visit clemburkedrummingproject.org for further information) where academics from different disciplines came together to not only explore the physiological demands of rock drumming but also the potential use of rock drumming as an intervention in research studies. Rock drumming is attractive to the scientist in that it is a unique activity that requires the coordination of multiple limbs to produce the required drumming pattern. Inherent demands relating to timing, tempo and volume must also be met. Therefore, the ability to manipulate these facets of drumming performance in a research setting is very appealing. In relation to potential research populations drumming has a universal fascination regardless of age, gender, culture, language competency and ethnicity. Anecdotal evidence suggests that drumming is a ‘cool’ activity that has a unique ‘language currency’ in terms of stimulating communication within and between those who can and cannot play the drums. The impetus for our research study came from parents of autistic children contacting us to express their belief that drumming was having a positive effect on their child’s physical and psychological behaviour. A review of the literature showed a range of anecdotal evidence in support of such statements (Freidman 2000) and an increase in empirical drumming based research being undertaken (Bungay 2010). More recent studies have reported psychosocial benefits such as enhanced communication (Maschi et al. 2010; 2012), emotional processing and tension reduction (Flores et al. 2016; Maschi et al. 2010; 2012), group cohesion and connectedness (Blackett et al. 2005), concentration, psychomotor coordination and posture (Chen et al. 2017). The majority of this work was undertaken with adolescents with very little work focused on younger age groups.

MedicalResearch.com Interview with: quadrant biosciencesSteven D. Hicks, MD PhD Penn State College of Medicine Department of Pediatrics Division of Academic General Pediatrics Hershey, PA, 17033‐0850 MedicalResearch.com: What is the background for this study? What are the main findings? Response: ​Previous studies have shown that disrupting the community of bacteria in the gut can lead to autism-like behavior in animals. In humans interventions aimed at improving the intestinal microbiome have also led to changes in autism behavior. Here, we examined whether autism-related changes in microbial activity extended to the mouth and throat. We were interested in this site because it provides the initial interface between host immunity and microbe exposure. By examining nearly 350 children with autism, typical development, or developmental delay (without autism) we identified 12 groups of oral bacteria with unique activity patterns in children with autism. Interestingly, microbial activity (measured by RNA sequencing) also differed between children with autism and gastrointestinal (GI) disturbances and peers with autism but no GI disturbance. Levels of several microbes also displayed correlations with measures of autism behaviors. We utilized microbial activity patterns to create diagnostic panels that displayed accuracy for distinguishing children with autism from peers with typical development (79.5% accuracy) or developmental delay (76.5% accuracy).

Roffman, MD Department of Psychiatry Mass General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Autism, schizophrenia, and other serious mental illness affecting young people are chronic, debilitating, and incurable at present.  Recent public health studies have associated prenatal exposure to folic acid, a B-vitamin, with reduced subsequent risk of these illnesses.  However, until this point, biological evidence supporting a causal relationship between prenatal folic acid exposure and reduced psychiatric risk has remained elusive. We leveraged the rollout of government-mandated folic acid fortification of grain products in the U.S. from 1996-98 as a "natural experiment" to determine whether increased prenatal folic acid exposure influenced subsequent brain development.  This intervention, implemented to reduce risk of spina bifida and other disabling neural tube defects in infants, rapidly doubled blood folate levels among women of childbearing age in surveillance studies. Across two large, independent cohorts of youths age 8 to 18 who received MRI scans, we observed increased cortical thickness, and a delay in age-related cortical thinning, in brain regions associated with schizophrenia risk among individuals who were born during or after the fortification rollout, compared to those born just before it.  Further, delayed cortical thinning also predicted reduced risk of psychosis spectrum symptoms, a finding that suggests biological plausibility in light of previous work demonstrating early and accelerated cortical thinning among school-aged individuals with autism or psychosis.

Response: Autism Spectrum Disorder (ASD) encompasses a large group of early‐onset developmental disorders that are collectively characterized by deficits in social interaction and communication as well as the expression of restricted, repetitive behaviors and interests. ASD is currently estimated to affect 1 in 59 children in the US. Despite this high prevalence, relatively little is know about the pathophysiology of ASD. The result of this is that no lab test exists for ASD and the diagnosis is based upon observations of the child. The average age of diagnosis is 4 years of age, but it is generally acknowledged that diagnosis at 2 years of age is possible and desirable.

What are the main findings?  Response: Many families of young adults with autism spectrum disorder (ASD) are concerned that they may have difficulty acquiring driver’s licenses and driving safely because of symptoms of ASD. However, the ability to drive opens the door to a variety of social, occupational, and educational experiences. We aimed to assess differences in simulated driving behaviors of young adults with ASD and those with typical development and to evaluate whether differences depended on level of driving experience and complexity of the driving task. On average, young adults with ASD had more difficulty regulating their speed and position within their lane compared with typically developing individuals even on a very basic rural route. After completing the basic route, drivers were required to engage in more complex tasks such as changing the radio or engaging in conversation while driving, driving through a construction zone, and following behind a truck. On complex driving tasks, drivers with ASD who had acquired licensure drove similarly to typically developing drivers who had acquired licensure. However, novice drivers with ASD had more difficulty than typically developing drivers regulating their speed and position within the lane.

Author Interviews, Autism, Environmental Risks, Fish, OBGYNE, Toxin Research / 23.05.2018

MedicalResearch.com Interview with: “Fish” by Dhruvaraj S is licensed under CC BY 2.0Dr Caroline M Taylor Wellcome Trust Research Fellow Centre for Child and Adolescent Health Bristol Medical School, University of Bristol Oakfield House, Oakfield Grove, Bristol MedicalResearch.com: What is the background for this study? Response: Mercury is a toxic metal that is widespread in the environment. In pregnancy, mercury in the mother’ bloodstream is transferred through the placenta to the fetus, where is can affect development of the nervous system. Mercury from vaccines has been the focus of attention particularly in regard to a link with autism in children. However, the amount of mercury used in the vaccines is small in comparison with mercury from the diet and atmospheric pollution, and in the EU at least, childhood vaccines no longer contain this preservative. The fear that mercury is linked to autism has persisted, despite increasing evidence that this is not the case. The aim of our study was to look at mercury from the diet rather than vaccines – specifically from fish – in pregnant women. We measured the women’s mercury levels in their blood and asked them about how much fish they ate. We then followed up their children for 9 years and recorded how many of them had autism diagnosed within that time. We also measured how many of them had autist traits by measuring their social and communication difficulties.  The data were part of the Children of the 90s study (Avon Longitudinal Study of Parents and Children – ALSPAC), which is based in Bristol, UK.

The patients had to have fairly good genetic screening per protocol and had confirmation of autism to participate. The use of cord blood was a pilot cross over double blind study with hypothesis that a post natal factor or immune dysregulation may add to the autism clinical phenotype. Cord blood ( the baby’s own from birth) is a safe source of mixed stem cell types and should be safe from rejection or autoimmune reaction in theory. Infusion /placebo or placebo/infusion was randomized and observed and tested every 3 months with switch to other wing of treatment at 0 and 6 months. Total observation was over 1 year.

What are the main findings? Response: Current clinical diagnosis and evaluations of Autism Spectrum Disorder (ASD). has remained subjective in nature. There is a need to have objective assessments for the disorder. We discovered in this study an important motion feature that was unknown before. This feature provides a clear screening of ASD. It gave a remarkable quantitative connection between the way children with ASD move and their psychiatric scores, like the IQ score and the Vineland Adaptive Behavior Scale. This connection we captured suggests that the motor feature may be an essential core feature characterizing ASD deficits, as well as neurodevelopment in general.

MedicalResearch.com Interview with: [caption id="attachment_39189" align="alignleft" width="140"]Tamara Rosen Tamara Rosen[/caption] Tamara Rosen Graduate student in Clinical Psychology Stony Brook University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Approximately 40 percent of youth with autism spectrum disorder (ASD) are diagnosed with a co-occurring anxiety disorder.  Social anxiety is a common presenting problem for these youth. Youth with ASD and increased social anxiety have heightened threat sensitivity, particularly in relation to performance fears, as measured by a brain signal response called the error-related negativity (ERN), which measures response to errors. The threat sensitivity-performance fears association remained even after controlling for anxiety symptoms other than social fearfulness.

MedicalResearch.com Interview with: [caption id="attachment_39092" align="alignleft" width="130"]Dr. Marte Bjørk, MD PhD Department of Clinical Medicine University of Bergen, Department of Neurology Haukeland University Hospital Bergen, Norway Dr. Marte Bjørk[/caption] Dr. Marte Bjørk, MD PhD Department of Clinical Medicine University of Bergen, Department of Neurology Haukeland University Hospital Bergen, Norway MedicalResearch.com: What is the background for this study? Response: In utero antiepileptic drug exposure are associated with neurodevelopmental problems in the child. We looked into if maternal folate during pregnancy could reduce the risk of autistic traits in children of women in need of antiepileptic drugs in pregnancy. The rationale for the hypothesis that folate could be beneficial, was that many antiepileptic drugs interact with folate metabolism. Folic acid supplement use is also associated with slightly reduced risk of autism in children of women from the general population.
