Q

What is a problem associated with the approach used in past research?

A

Historically, research has involved researchers forming hypotheses and then seeking out certain populations to test these hypotheses

They then analyse their data and publish their conclusions relating to that population

The research decides what is important by doing research in specific areas and making specific hypothesis they think are important.

Q

What is co-production?

A

Now recognised that making assumptions, testing assumptions and publishing conclusions about a certain population without input from that population is not good practice.

People with neurodevelopmental conditions are often left out of the very research which is about them!

Often, research focusses on asking family members, educators and clinicians about the individual

A lot of these individuals could answer questions too!

Term origins in HIV research which worked with HIV patients, 1980s. Very driven by the autistic community.

Q

What is a problem with co-production?

A

Autistic advocates argue that conventional research provides too few opportunities for genuine engagement with autistic people, contributing to “social disenfranchisement” among autistic people.

Recent research demonstrates that world wide autistic people, their families, educators, and clinicians feel that autism research generally fails to describe the nature of autistic life experiences.

Q

What is the definition of co-production?

A

No dictionary definition.
But it is the process of conducting research in partnership with the population you are focussing on.

Co-production < participants < involvement < consultation

Q

Why co produce?

(Pellicano et al., 2020)

A

We might get more effective research if we actively involve community members who can direct attention to aspects of experience that are routinely missed without such input:

Effective in informing science/theory
Effective in applying to daily lives.

Clear ethical reasons for involvement in research. Marginalized communities are often not involved in making decisions that affect them.
The disability rights mantra, “nothing about us, without us,” people should be able to contribute to research that could in some way affect their lives (Friesen et al., 2021)

Q

What is meant by expert by experience?

Thompson-Hodgetts (2022)

A

open letter as a non-autistic autism researcher
Research demonstrates positive effects:
Better insights, more involved, can have applied affects (instead of being disconnected)
Challenges our preconceptions

PTT important in light of research focussing on current real world event&raquo_space; sadly although co-production is increasingly popular in autism research, this is not the case across all condition

Q

How did COVID affect Down syndrome?

A

40Y+ Adults were 4x more likely to be hospitalized and 10x more likely to die from COVID-19 (Clift et al., 2020).

Adults with DS faced unique challenges from societal efforts to curb the spread of COVID-19.

Quarantining and social distancing likely led to reductions in disability programs that adults with DS normally rely on.

Adults with DS are often not able to benefit from telehealth or virtual services to the same extent as their non-DS peers (Krysta et al., 2021)

The pandemic may also have reduced activities important for mood & behavior regulation and overall health including exercise and time spent outdoors - these activities are often fostered by disability programs (Rubenstein et al., 2020)

Q

What changes affect mental health?

A

Daily life changes caused by COVID as well as new stressors brought on by the pandemic may have consequences for modd and behaviour.
Sep 2020 - Feb 2021: caregiver of DS
1/3 of individuals were more irritable or easily angered
52% were more anxious
41% were more sad/depressed/unhappy relative to prepandemic

The majority of changes in mood and behavior were of modest severity.

Q

What were the NICE guideline with COVID?

A

During the pandemic NICE published a scale setting out who to prioritise for care if resources ran short.
Those who need support for day-to-day living (e.g. people with learning disabilities) were not prioritised on this scale: Led to many people being issued a do-not-resuscitate (DNR).
Mencap contacted NICE who agreed the scale shouldn’t apply to people with learning disabilities & updated their guidance.
NHS England responded quickly, but still some people who have a DNR who don’t know!

26
Which charity challenged the 'Do Not Resuscitate' order placed on people with a learning disability?
MENCAP
27
What has a role in autism prevalence?
the role of genetic and environmental factors
28
What's the role of genetics in autism prevalence?
Higher co-occurrence of ASC in monozygotic twins than dizygotic twins. 1st degree relatives of autistic people have an increase in behavioural or cognitive features associated with ASC. = The broader Autism phenotype ASC often co-occurs with genetic conditions (e.g. 16p11.2 and Sotos syndrome) = Sotos Syndrome
29
What is the broader autism phenotype?
1st degree relatives of autistic people have an increase in behavioural or cognitive features associated with ASC.
30
What is sotos syndrome?
ASC often co-occurs with genetic conditions (e.g. 16p11.2 and Sotos syndrome)
31
What have twin studies discovered about autism?
Monozygotic = twins from a single egg, i.e. 100% shared genetic material. Dizygotic = twins from 2 eggs, i.e. 50% shared genetic material First twin study of autism in 1977 Study in 2011 (Hallmayer, et al.) found: Concordance rate of up to 77% in Mz twins Concordance rate of 31% in Dz twins
32
What is meant my Magenta ? | autism as a spectrum
are people who fit on the questionnaire on the opposite side of their diagnosis. Magenta on the red side are autistic participants that scores bellow the autism traits questionnaire and magenta on the blue are undiagnosed participants that have scored higher.
33
How would you define the broad autism phenotype?
Behavioural features associated with ASC (social interaction / friendships, pragmatics and speech) investigated in parents of: -multi-incidence of autism (MIAF) families -single-incidence of autism families (SIAF) -Families with children with Down’s syndrome MIAF & SIAF Showed an increase in ASC-related features. Considered to provide evidence for the “Broad Autism Phenotype”, and also evidence for a genetic origin of ASC.
34
What is the definition and prevalence of sotos syndrome?
“overgrowth” syndrome Prevalence = 1 in 14,000 Deletions on chromosome 5 involving the NSD1 gene. Diagnostic criteria: overgrowth with advanced bone age, macrocephaly, characteristic facial appearance and intellectual disability.
35
What did Lane et al 2017 find?
Recruited 78 individuals with Sotos syndrome. Measured traits of autism using the Social Responsiveness Scale. Found that 83% of participants scored above clinical cut-off for ASC.
36
Why does ASC often co-occur with other genetic conditions?
The fact that ASC occurs in neurodevelopmental conditions with known genetic origin (e.g. Sotos syndrome, Fragile X syndrome, 16p11.2) highlights that genetic alterations are associated with ASC symptoms, providing support for the argument that there is genetic association to ASC. Some genes are more linked with ASC symptoms than others.
37
How complex is the genetics of ASC?
involves a large nb of different genes and most likely interaction between different genes. Over 100 different genes have been strongly linked to autism. These genes are mostly involved in brain development. However, only 10 to 20% of autism cases are accounted for by known genetic abnormality.
38
What environmental factors are linked to autism?
Modelling, Refrigerated, vaccines, lead, pollution ect. a lot of miss information
39
What do we mean by ‘Environmental Epidemiology?’
Observation of human populations to infer the environmental causes of a condition or disease.
40
What is important to avoid?
Important to avoid “Bad Science” / unscientific reports in the media. Important to carry out good, rigorous science in an attempt to understand potential environmental causes of ASC. Researchers recognise that environmental factors may contribute, in part, to the growing incidence of ASC.
41
What is meant by bad science?
In 1998, a paper was published (Wakefield et al.) that claimed there was a link between the MMR vaccine and autism. This paper was based on a (very small) sample of 12 children. It led to a media frenzy and to 1000s of people across the globe choosing not to vaccinate their children. Consequently, more people are now contracting measles across the world
42
What was the impact of Wakefield et al.'s work?
Global increase in measles. Lack of trust around research on environmental causes of autism
43
Does the MMR cause autism?
The paper was later retracted as there was evidence that parts of the work were fraudulent. Many follow up studies have since found no evidence for a link between the MMR vaccine and autism. In 2019, a paper found no evidence for a link between MMR and autism, in a population sample of over 650,000 children.
44
What environmental factors are linked to autism?
Prenatal viral infection (e.g. influenza or rubella) Maternal diabetes Maternal obesity Prenatal Stress Teratogens e.g. valproic acid (for epilepsy) or psychoactive drugs Pesticide exposure during first 8 weeks of pregnancy Parental age (advanced maternal age) Air pollution NO CONCLUSIVE FACTORS IDENTIFIED SO FAR
45
What is tricky to identify in ASC and the environment?
Incredibly tricky to identify clear environmental causes Analysing environmental influences = correlations Correlation =/= Causation “Drawing a direct line between cause and effect in a messy, complex world is inherently challenging.”
46
How can we try to establish causality?
Environmental epidemiology: Hill’s criteria
47
What are Hill's Criteria?
Strength Analogy Temporality Cause Specificity Experiment Consistency Biological Gradient Plausibility Coherence
48
What is meant by strength? | Hill's criteria
how strong is the relationship between the variables?
49
What is meant by analogy? | Hill's Criteria
Are there any other similar relationships?
50
What is meant by temporality?
Effect has to happen after the Cause
51
What is meant by coherence? | Hill's criteria
Do these findings match up with lab studies or well established relationships?
52
What is meant by specificity? | Hill's Criteria
The effect is only found in relation to the cause OR there is only one effect associated with the cause
53
What is meant by experiment? | Hill's criteria
Use well designed and conducted observational studies
54
What's meant by consistency? | Hill's critieria
Do we find similar findings in different contexts?
55
What is meant by biological gradient? | Hill's criteria
Greater exposure = greater incidence
56
What is meant by plausibility? | Hill's criteria
How plausible is this explanation?
57
Are results easily challenged? | Enviornmental epidemiology
The results of one study are easily challenged: Surén et al., (2013) - 85,176 children – folic acid during pregnancy reduced risk of autism Virk et al., (2016) - 38,035 mothers – no evidence that folic acid reduces the risk of autism
58
What takes numerous independent studies and combine their results to see if the relationship remains?
Environmental research is observational: not fully controlled > extraneous variables are also recorded > results of one study are easily challenged > how can we be confident in the results of our study ? > Meta analysis
59
What was the meta-analysis on air pollution?
Search Terms: multiple words associated with air pollution and autism. Initial set of papers are screened to identify relevant work that fits the inclusion criteria.
60
What do odds ratio provide?
Odds ratio provides a statistical method for understanding the association between exposure and an outcome. For example, what is the likelihood that cigarette smoking causes lung cancer?
61
How do we interpret odds ratios?
OR = 1 exposure to the cause (cigarettes) does not lead to an effect (cigarette smoking isn’t linked to lung cancer). OR < 1 Greater exposure to the cause (cigarettes) is associated with less of an effect (less chance of lung cancer) OR > 1 Greater exposure to the cause (cigarettes) is associated with a larger effect (greater chance of lung cancer).
62
What did meta-analysis of studies looking at association between particulate matter and ASC diagnosis?
"Particulate Matter is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulphates), organic chemicals, metals, and soil or dust particles.” Combined data shows a small but significant association between particulate matter & ASC.
63
What is showing risk of ASC from MMR?
Now that I’ve explained odds ratios, let’s look at the risk of ASC following MMR. ALL datasets showed odds ratio <1, i.e. no association between MMR and ASC.
64
Do Environmental Factors cause ASC?
Measuring environmental exposure accurately is very difficult. Very little clear evidence for environmental causes of ASC. Possible suggestions focus on particulate matter as a risk factor. HOWEVER evidence for a direct causal link between environmental factors and ASC is generally weak.
65
What is the gene/environment interaction in autism?
Genetic Risk + Environmental risk = increased likelihood of developmental condition (e.g. ASC)
66
What has animal models showned about the direct effect on MET expression?
Link between air pollution and ASC risk Link between air pollution and MET gene Link ASC risk and Met gene
67
What gene is associate with increased risk of developing ASC?
One (of the many) genes that has been associated with increased risk of developing ASC is the MET gene. The MET gene codes for proteins that trigger mitogenesis [cell division] and morphogenesis [structural development].
68
What did a study aimed to investigate whether there is an interaction between alterations to the MET gene and air pollution and ASC risk?
252 autistic children, 156 neurotypical controls recruited from Californian preschools. MET genotype was assessed via blood test. Exposure to air pollution was measured/estimated for each participant. Results showed an interaction effect: children with both an alteration to the MET gene AND increased exposure to air pollution were at increased risk of autism than those with just the MET alteration, or just those with increased exposure to air pollution.
69
What did Thompson-Hodgetts 2022 findings? | Reading
Engaging with autistic people as a non-autistic autism researcher acknowledges their lived experience—a perspective that I do not have, respects requests from the autistic community to be more actively engaged in autism research. The author acknowledges the risks of non-autistic "experts" teaching about autism (Walker, 2021) and recognizes the value of collaborative experiences with autistic colleagues. They recommend that non-autistic autism researchers become aware of their own positionality and engage autistic people as experts in their research.
70
What did Bobo et al. 2020 find? | Reading
The results of our survey suggest that children and adolescents with attention deficit hyperactivity disorder do not systematically have worsening their symptoms during confinement. the potential anxiety-provoking nature of this health and economic crisis are all factors that can influence the symptomatology of these children and adolescents with ADHD.
