Association between adverse childhood experiences and self-reported health-risk behaviors among cancer survivors: A population-based study.

AIMS: Existing evidence shows that people who report Adverse Childhood Experiences (ACEs) are more likely to exhibit health-risk behaviors. However, limited research on this topic pertains to oncology population. We aim to address this knowledge gap by estimating the prevalence of ACEs and investigating their association with self-reported health-risk behaviors among adult cancer survivors living in the U.S. METHODS: We conducted a secondary analysis using cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System ACE module. We included 4,126 adults, aged ≥18 years, with a history of cancer. The outcome variable was self-reported health-risk behaviors, which included cigarette smoking, e-cigarette use, and binge alcohol drinking. Self-reported ACEs history was the primary independent variable, comprised of 11 questions regarding child abuse and dysfunctional households. We conducted descriptive statistics and multivariable logistic regression to describe the relationship between the ACE history and health-risk behaviors. RESULTS: Overall, 84.2% of cancer survivors self-reported as White, 58.4% were women, and 76.6% were aged 65+ years. Nearly two-thirds of the sample (63.2%) self-reported at least one ACE (prior to age 18) and 21.7% engaged in ≥1 health-risk-behaviors, such as cigarette smoking, binge alcohol drinking, or e-cigarette use. Experiencing ≥3 ACEs was associated with 145% increased odds of reporting at least one health-risk behavior (OR = 2.45, 95% CI [1.78-3.38]) when compared to those without a history of ACEs. Besides, survivors who were younger, divorced, less educated, and had low income had higher odds of reporting at least one health-risk behavior. CONCLUSIONS: Overall, a history of ACEs is associated with health-risk behaviors. These all can negatively impact cancer survivors' overall well-being. Early screening for ACE during oncologic visits can be a protective measure for preventing health-risk behaviors among cancer survivors.

Investigating the effects of valproic acid on placental epigenetic modifications and development in the CD-1 mouse model.

Gestational exposure to the anticonvulsant drug valproic acid (VPA) is associated with congenital malformations and neurodevelopmental disorders through its action as a histone deacetylase inhibitor. VPA can elicit placental toxicity and affect placental growth and development. The objective of this study was to evaluate the impact of maternal exposure to VPA on the mouse placenta following exposure on gestational day (GD) 13 since previous studies have shown that mice exposed at this time during gestation give birth to offspring with an autism spectrum disorder-like phenotype. We exposed CD-1 dams to a teratogenic dose (600 mg/kg) of VPA or saline on GD13 and assessed fetoplacental growth and development on GD18. We evaluated epigenetic modifications, including acetylated histone H4 (H4ac), methylated H3K4 (H3K4me2) using immunohistochemistry, and global DNA methylation in the placenta at 1, 3, and 24 h following maternal exposure on GD13. In utero exposure to VPA on GD13 significantly decreased placental weight and increased fetal resorptions. Moreover, VPA significantly increased the staining intensity of histone H4 acetylation and H3K4 di-methylation across the placenta at 1 and 3 h post maternal dose. Our results also demonstrate that VPA significantly decreased global DNA methylation levels in placental tissue. These results show that gestational exposure to VPA interferes with placental growth and elicits epigenetic modifications, which may play a vital role in VPA-induced developmental toxicity.

Bacteriophage Morrigan, which was isolated from soil using Microbacterium foliorum NRRL B-24224, is lytic with siphovirus morphology. Morrigan's 40,509-bp genome has a GC content of 62.8% and 66 putative protein-coding genes, of which 31 could be assigned putative functions. Based on gene content similarity to actinobacteriophages, Morrigan is assigned to subcluster EA6.

Qualitative analysis of community pharmacy-based COVID-19 immunization service operations.

BACKGROUND: The unprecedented coronavirus disease 2019 (COVID-19) pandemic has generated worldwide impacts while positioning community pharmacies as easily accessible immunizers to rollout the COVID-19 vaccine. OBJECTIVES: This study describes community pharmacists' experiences, success stories, and lessons learned from providing COVID-19 immunization services. METHODS: This study was conducted in February to March 2022 using semistructured interviews with licensed pharmacists practicing full-time in Alabama community pharmacies. Transcribed interviews' content analysis was conducted by 2 independent coders in ATLAS.ti software. RESULTS: Nineteen interviews were completed. Pharmacists' experiences in the implementation of COVID-19 immunization services are described across 4 themes: (1) on-site and off-site immunization locations, (2) roles and responsibilities of pharmacy personnel, (3) vaccine storage and administration, and (4) vaccine waste reduction and immunization uptake strategies. This study found that pharmacists' ability to adapt is vital to maintaining their ability to offer immunization services and other services. Pharmacists' capacity for adapting is exemplified through their ability to acclimate to becoming a primary hub of outpatient health care services, accommodating to COVID-19 social distancing and vaccine guidelines, and disseminating a novel vaccine with varying supply and demand. In addition, pharmacies gathered and maintained waitlists of patients and adopted an appointment-based model as to predict, plan, and provide for patients. Pharmacists also used reactive techniques and workflow aspects to dissuade COVID-19 vaccine waste such as in contacting interested patients on waitlists or switching to a walk-in acceptance model. The COVID-19 pandemic elicited unprecedented alterations to the legal, health care responsibilities granted to pharmacy staff with participants describing pharmacy technicians as making a considerable impact to pharmacies' workflow. CONCLUSIONS: Pharmacists stepped up as frontline providers during a time of public health emergency with their diverse experiences granting policy makers and researchers much to learn from as, in their communities, pharmacists have continued to increase access to care during a national health crisis.

The Good, the Bad, and the Vision: Exploring the Mental Health Care Experiences of Transitional-Aged Youth Using the Photovoice Method.

Transitional-aged youth (TAY) between the ages of 16 and 24 experience higher rates of mental distress than any other age group. It has long been recognized that stability, consistency, and continuity in mental health care delivery are of paramount importance; however, the disjointed progression from paediatric to adult psychiatric services leaves many TAY vulnerable to deleterious health outcomes. In Spring 2019, eight TAY living with mental health challenges participated in a Photovoice study designed to: (1) illuminate their individual transition experiences; and, (2) support a collective vision for optimal mental health care at this nexus. Participants took photographs that reflected three weekly topics-the good, the bad, and the vision-and engaged in a series of three corresponding photo-elicitation focus group sessions. Twenty-four images with accompanying titles and captions were sorted into nine participant-selected themes. Findings contribute to an enhanced awareness of psychiatric service delivery gaps experienced by TAY, and advocate for seamless and supportive transitions that more effectively meet the mental health care needs of this population.

Structural violence: An evolutionary concept analysis.

AIMS: To enhance conceptual clarity and interdisciplinary understanding of structural violence, and to illuminate its implications for contemporary social justice and health equity research, by: (1) synthesizing scholarly literature pertaining to structural violence and health; (2) defining its key attributes, antecedents, consequences and characteristics; (3) contextually situating this phenomenon over time and across disciplines. DESIGN: A comprehensive review of scholarly health literature pertaining to 'structural violence' or its surrogate term 'structural determinants of health' was guided by a Research and Education Librarian. DATA SOURCES: In November 2019 and again in April 2021, CINAHL, Embase, Global Health, Medline, PsycINFO, PubMed and Scopus electronic databases were searched for peer-reviewed articles that described structural violence in the context of health. Of the 238 unique records identified, 32 articles were selected for inclusion and comprise the review sample. REVIEW METHODS: Using Beth Rodgers' evolutionary concept analysis method, articles were comparatively analysed to identify key attributes, antecedents and consequences associated with the concept's use in health research. RESULTS: The five interrelated attributes characterizing structural violence are: power, marginality, oppression, adversity and trauma. Hegemonic social, cultural, economic and political systems serve as antecedents, whilst the consequences of structural violence can be broadly classified as health inequity, injustice and indignity, and social disorganization. CONCLUSION: This analysis contributes to conceptual clarity and mutual understanding of the usage, application and significance of structural violence across health disciplines and provides a strong foundation for continued concept development and operationalization. Further research is needed to substantiate the relationship between structural violence and health inequity.

Fathead Minnows Exposed to Organic Compounds from Oil Sands Tailings as Embryos Have Reduced Survival, Impaired Development, and Altered Behaviors That Persist into Larval Stages.

Our study evaluated whether exposure to naphthenic acid fraction compounds (NAFCs) extracted from oil sands process-affected waters (OSPW) has adverse effects on fish embryos that persist into later life. We exposed fathead minnow (Pimephales promelas) embryos to concentrations of NAFCs found in OSPW (2.5-54 mg/L) for 7 days (1 day postfertilization to hatch), then raised surviving larvae in outdoor mesocosms of uncontaminated lake water for 1 month. Embryos exposed to NAFCs were more likely to exhibit malformations (by up to 8-fold) and had slower heart rates (by up to 24%) compared to controls. Fish raised in uncontaminated lake water following exposure to NAFCs as embryos, were 2.5-fold less likely to survive during the larval stage than control fish. These fish also showed up to a 45% decrease in swim activity and a 36% increase in swim burst events during behavioral tests relative to controls. We conclude that exposure to NAFCs during the embryonic stage can have lasting effects on fish survival, physiology, and behavior that persist at least through the larval stage. These findings of delayed mortalities and persistent sublethal effects of embryonic NAFC exposure are relevant to informing the development of regulations on treated OSPW releases from mining operations.

"I Fell through the Cracks": Navigating the Disjointed Transition from Paediatric to Adult Psychiatric Services.

The transition from adolescence to adulthood is a tumultuous time riddled with stress, confusion, and uncertainty. An abrupt shift in biobehavioural development between the ages of 16 and 24 corresponds with an increase in mental health challenges; thereby necessitating comprehensive and coordinated psychiatric services that bridge pediatric and adult care realms. Unfortunately, this transition is often unsupportive and disjointed, leaving many transitional-aged youth (TAY) overwhelmed and ill-equipped to cope with the increased demands of adulthood independently. Eight TAY with mental health challenges were invited to participate in a PhotoVoice study that explored the strengths and shortcomings of this transition process, through a combination of photography and photo-elicitation focus group discussions. A descriptive qualitative approach was used to analyze all participant dialogue. Four themes emerged from the data: accessibility, coordination, independence, and support. Participant insights illuminated critical gaps in mental health care delivery, but also revealed novel solutions and opportunities for transformational change.

Promoting Attachment Through Healing (PATH): Results of a retrospective feasibility study providing trauma-and-violence-informed care to pregnant women.

AIM: To evaluate the impact of a trauma and violence-informed cognitive behavioural therapy (TVICBT) intervention, compared with standard care on mental health, coping, bonding and maternal-infant attachment among pregnant women with a history of intimate partner violence and who displayed symptomatology consistent with anxiety, depression or post-traumatic stress disorder (PTSD). DESIGN: A mixed-methods case study design was employed, where women either received standard perinatal care or were referred to a specialized TVICBT program. METHODS: Data were collected through a retrospective obstetric medical chart audit in 2017 at an Ontario hospital in a large urban centre. Multiple choice and 'yes/no' questions were analysed using measures of central tendency and dispersion, in addition to frequency counts. Qualitative data from clinical notes were subjected to an inductive content analysis approach to identify key concepts. RESULTS: In total, 69 women participated (intervention group = 37, standard care group = 32). Prevalence of mental illness between groups was consistent, apart from the TVICBT group having a significant increase in PTSD. In the TVICBT group, 83.8% of women (n = 31) expressed perinatal concerns, compared with only 37.5% (n = 12) of the standard care group. More women in the intervention group (94.6%, n = 35) coped successfully in the intrapartum period than the standard care group (78.1%, n = 25). However, more women in the standard care group (97.0%, n = 31) exhibited appropriate bonding behaviours than the TVICBT group (88.6%, n = 31). CONCLUSION: The TVICBT intervention was effective in assisting women to identify triggers during their pregnancy journey, develop appropriate coping strategies and advocate for their needs to best cope. IMPACT: TVICBT offers an effective, individualized, trauma and violence-informed approach to optimize the health outcomes of perinatal women and their infants by promoting positive coping and maternal-infant bonding, thus filling an existing practice gap of a lack of individualized, trauma-informed care.

Sharing Personal Experiences of Accessibility and Knowledge of Violence: A Qualitative Study.

In North America, the most common societal response to intimate partner violence (IPV) has been the establishment of women's shelters for temporary housing and security. Rurality further compounds the challenges women experiencing IPV face, with unique barriers from their urban counterparts. This study sought to explore the intersection of rural women's health care experiences within the context of IPV. Eight rural women living in Southwestern Ontario, who had experienced IPV, had used women's shelter services, and who had accessed health care services in the preceding 6 months were interviewed. Using a feminist, intersectional lens, we collected and analyzed qualitative data using an interpretive description approach. Findings demonstrated that women were able to identify strengths and opportunities from their experiences, but significant challenges also exist for rural women seeking health care who experience IPV. Our findings underscore the need for filling of policy gaps between health care and the services women use. We propose that further research is needed on alternative, integrated models of shelter services that address health care needs for women experiencing IPV.

Supporting the use of patient portals in mental health settings: a scoping review.

With the increased use of patient portals in acute and chronic care settings as a strategy to support patient care and improve patient-centric care, there is still little known about the impact of patient portals in mental health contexts. The purposes of this review were to: 1) identify the critical success factors for successful patient portal implementation and adoption among end-users that could be utilized in a mental health setting; 2) uncover what we know about existing mental health portals and their effectiveness for end-users; and 3) determine what indicators are being used to evaluate existing patient portals for end-users that may be applied in a mental health context. This scoping review was conducted through a search of six electronic databases including Medline, EMBASE, PsycINFO, and CINAHL for articles published between 2007 and 2021. A total of 31 articles were included in the review. Critical success factors of patient portal implementation included those related to education, usefulness, usability, culture, and resources. Only two patient portals had articles published related to their effectiveness for end-users (one in Canada and the other in the United States). More than 100 measures of process (n = 73) and outcome (n = 59) indicators were extracted from the studies and mapped to the Benefits Evaluation Framework. Patient portals carry great potential to improve patient care, but more attention needs to be given to ensure they are being evaluated through the development and implementation phases with the end-users in mind. Further understanding of process indicators relating to use are essential for long-term patient adoption of portals to obtain their potential benefits.

Maternal Experiences of Racial Discrimination, Child Indicators of Toxic Stress, and the Minding the Baby Early Home Visiting Intervention.

BACKGROUND: Racism is a significant source of toxic stress and a root cause of health inequities. Emerging evidence suggests that exposure to vicarious racism (i.e., racism experienced by a caregiver) is associated with poor child health and development, but associations with biological indicators of toxic stress have not been well studied. It is also unknown whether two-generation interventions, such as early home visiting programs, may help to mitigate the harmful effects of vicarious racism. OBJECTIVE: The purpose of this study was to examine associations between maternal experiences of racial discrimination and child indicators of toxic stress and to test whether relationships are moderated by prior participation in Minding the Baby (MTB), an attachment-based early home visiting intervention. METHODS: Ninety-seven maternal-child dyads (n = 43 intervention dyads, n = 54 control dyads) enrolled in the MTB Early School Age follow-up study. Mothers reported on racial discrimination using the Experiences of Discrimination Scale. Child indicators of toxic stress included salivary biomarkers of inflammation (e.g., C-reactive protein, panel of pro-inflammatory cytokines), body mass index, and maternally reported child behavioral problems. We used linear regression to examine associations between maternal experiences of racial discrimination and child indicators of toxic stress and included an interaction term between experiences of discrimination and MTB group assignment (intervention vs. control) to test moderating effects of the MTB intervention. RESULTS: Mothers identified as Black/African American (33%) and Hispanic/Latina (64%). In adjusted models, maternal experiences of racial discrimination were associated with elevated salivary interleukin-6 and tumor necrosis factor-α levels in children, but not child body mass index or behavior. Prior participation in the MTB intervention moderated the relationship between maternal experiences of discrimination and child interleukin-6 levels. DISCUSSION: Results of this study suggest that racism may contribute to the biological embedding of early adversity through influences on inflammation, but additional research with serum markers is needed to better understand this relationship. Improved understanding of the relationships among vicarious racism, protective factors, and childhood toxic stress is necessary to inform family and systemic-level intervention.

Validation of the Injured Trauma Survivor Screen: An American Association for the Surgery of Trauma multi-institutional trial.

BACKGROUND: Psychological distress is common following a traumatic injury event. The Injured Trauma Survivor Screen (ITSS) was developed at a level 1 trauma center to assess for posttraumatic stress disorder (PTSD) and major depressive episode (MDE) following admission for a traumatic injury. The ITSS sensitivity and specificity were analyzed 1 to 3 and 6 to 9 months postinjury to test the validity across trauma centers. METHOD: Four level 1 trauma centers from the East, Midwest, South, and West in the United States recruited 375 eligible adult inpatients (excluded participants included those with moderate or severe traumatic brain injury, whose injury was self-inflicted, were noncommunicative, or were non-English speaking). Baseline sample (White/Caucasian, 63.2%; male, 62.4%; mean (SD) age, 45 (17.11) years; injured by motor vehicle collision, 42.4%) measurements were conducted during index hospitalization. At first follow-up, 69.6% (n = 261) were retained; at second follow-up, 61.3% (n = 230) were retained. Measurements included the ITSS, PTSD Checklist for DSM-5, Center for Epidemiologic Studies Depression Scale-Revised, and Clinician-Administered PTSD Scaled for DSM 5. RESULTS: At follow-up 1, the ITSS PTSD subscale had a sensitivity of 75% and specificity of 78.8%, and the MDE subscale had a sensitivity of 80.4% and specificity of 65.6%. At follow-up 2, the PTSD subscale had a sensitivity of 72.7% and specificity of 83.1%, and the MDE subscale had a sensitivity of 76.1% and specificity of 68.3%. A combined risk group using two symptom based measures administered at baseline produced increased specificity. CONCLUSION: The nine-item ITSS continues to be an efficient and effective risk screen for PTSD and MDE following traumatic injury requiring hospitalization. This multi-institutional validation study creates a solid foundation for further exploration of the generalizability of this screen's psychometric properties in distinct populations. LEVEL OF EVIDENCE: Prognostic study, level III.

The Impact of Obstructive Sleep Apnea on Balance, Gait, and Falls Risk: A Narrative Review of the Literature.

Falls-related hospitalization and injury rates are steadily increasing globally due to a growth in the aging population, and the associated health problems that increase risk of falls. One such associated health problem is sleep disturbances and disorders. Recent cohort studies have shown that subjectively reported poor quality sleep is associated with an increased risk of falls. Obstructive sleep apnea (OSA) is a common sleep disorder characterized by the repetitive reductions, or cessation, of airflow. Some studies have shown that OSA impairs posture/balance and gait with nocturnal hypoxemia the likely main cause. Emerging evidence suggests that treating OSA by continuous positive airway pressure (CPAP) can improve gait, but no studies to date have examined the effect of CPAP on posture/balance. The overall control of balance relies on a complex interaction between several physiological functions including vestibular, muscle, visual, and cognitive functions. We postulate that OSA impacts balance by affecting these different systems to various degrees, with the nocturnal hypoxic burden likely playing an important role. Importantly, these impairments in balance/posture and possible falls risk may be alleviated by OSA treatment. Larger mechanistic studies are needed to properly elucidate how OSA affects falls risk and future large-scale randomized control trials are needed to determine the effectiveness of OSA treatment in reducing the risk of falls.

Exploring mothers' experiences of trauma and violence-informed cognitive behavioural therapy following intimate partner violence: a qualitative case analysis.

PURPOSE: Intimate partner violence (IPV) is a pervasive public health issue impacting one in three women, worldwide. Broadly defined as any act of coercive control within the context of an intimate relationship, IPV often results in significant negative health outcomes. Cognitive Behavioral Therapy (CBT), a mainstay treatment for relational trauma, has particular relevance for women undergoing the many transformations associated with the perinatal period. The findings of this case analysis build upon existing literature supporting the positive impact of Trauma and Violence- Informed CBT (TVICBT) for women who have experienced IPV and are living with mental health challenges. METHODS: As part of a larger mixed-methods study, three women who experienced IPV and received TVICBT during pregnancy participated in in-depth, semi-structured interviews to determine the perceived value and acceptability of this intervention. FINDINGS: Insights gained herein, serve to enrich current evidence, suggesting that TVICBT provided during pregnancy may hold promise for the treatment of IPV-related mood and anxiety disorders. CONCLUSIONS: Given that improved perinatal mental health has been linked to enhanced maternal resiliency and quality of life, greater maternal-infant attachment, and positive child health outcomes, this research has the potential to bridge the critical knowledge gap at the intersection of motherhood, trauma, and mental health.

Examining the Impact of Trauma-Informed Cognitive Behavioral Therapy on Perinatal Mental Health Outcomes Among Survivors of Intimate Partner Violence (The PATH Study): Protocol for a Feasibility Study.

BACKGROUND: Intimate partner violence (IPV) is a pervasive public health problem, impacting the health and quality of life of survivors worldwide. The trauma of IPV is associated with a high incidence of mental illness, namely depressive and anxiety disorders, and posttraumatic stress disorder (PTSD). Moreover, literature endorses cognitive behavioral therapy (CBT) interventions as a gold standard for those with symptomatology consistent with anxiety disorders, mood disorders, and PTSD. However, efficacy has not been evaluated among a population of pregnant survivors of IPV. OBJECTIVE: We present the protocol that will be used to explore the efficacy of trauma-informed cognitive behavioral therapy on maternal and child health outcomes for pregnant women with PTSD, depression, or anxiety symptomatology resulting from IPV. A secondary aim will be to test the validity and feasibility of study methodology to support the successful implementation of a full-scale randomized controlled trial. METHODS: The Promoting Attachment Through Healing (PATH) study will use a mixed-methods approach grounded in an intersectional feminist framework to explore the effectiveness of trauma-informed CBT for pregnant survivors of IPV. Study participants will be recruited through the hospital-based Perinatal Mental Health Clinic (London, Ontario, Canada). A feasibility sample of 20 pregnant women (cohort 1) will be selected to engage in an eight-session antenatal CBT intervention facilitated by the program's perinatal clinical nurse specialist, with evaluation at baseline, at two months postpartum (intervention and online questionnaire), and at six and twelve months postpartum (online questionnaire only). Concurrently, we will conduct a retrospective audit of 100 medical charts (cohort 2; 50 charts of perinatal women who received CBT and 50 charts of women who did not receive perinatal CBT) from the past five years. The efficacy of the intervention will be based on a reduction of mental illness symptomatology, improved maternal-infant attachment, maternal coping, and maternal quality of life. Additionally, the feasibility of the protocol and acceptability of the intervention from the women's perspective will be examined. Inductive content analysis of all qualitative data will be used to determine common themes. Additionally, descriptive statistics, including measures of central tendency and dispersion, will be computed for all continuous variables. Alternatively, frequency tables will be constructed for all categorical variables. RESULTS: The work reported here is in the proposal phase. Once the protocol is implemented, we will report the results in a follow-up paper. Participant recruitment for cohort 1 has started and we have finished data collection for cohort 2. It is anticipated that the results will be available by the end of 2018. CONCLUSIONS: Findings will assess the acceptability of the study methodology and protocol for a full-scale randomized controlled trial. Furthermore, if CBT is proven effective for pregnant survivors of IPV, this intervention could be readily adopted by health care and social support services, thereby contributing to an improved standard of care for this unique population.

Versatile transduction scheme based on electrolyte-gated organic field-effect transistor used as immunoassay readout system.

We report on an innovative heterogeneous bisphenol A (BPA) immunoassay based on an electrolyte-gated organic field-effect transistor whose organic semiconductor is poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) co-crystallized with an alkyl derivative of bisphenol A. A decrease of the transistor output current is first observed upon antibody specific binding onto the organic semiconductor. Upon bisphenol A addition, the competitive dissociation of the antibody from the semiconductor surface leads to an opposite increase of the output current. We present here a proof-of-concept for bisphenol A detection; the device could be readily adapted to other small organic molecules of interest and is a promising tool for simple, low-cost, portable and easy-to-use biosensors.

Magno- and Parvocellular Contrast Responses in Varying Degrees of Autistic Trait.

Autistic tendency has been associated with altered visual perception, especially impaired visual motion sensitivity and global/local integration, as well as enhanced visual search and local shape recognition. However, the neurophysiological mechanisms underlying these abnormalities remain poorly defined. The current study recruited 29 young adults displaying low, middle or high autistic trait as measured by Baron-Cohen's Autism spectrum Quotient (AQ), and measured motion coherence thresholds psychophysically, with manipulation of dot lifetime and stimulus contrast, as well as nonlinear cortical visual evoked potentials (VEPs) over a range of temporal luminance contrast levels from 10% to 95%. Contrast response functions extracted from the major first order and second order Wiener kernel peaks of the VEPs showed consistent variation with AQ group, and Naka-Rushton fits enabled contrast gain and semi-saturation contrasts to be elicited for each peak. A short latency second order response (previously associated with magnocellular processing) with high contrast gain and a saturating contrast response function showed higher amplitude for the High AQ (compared with Mid and Low groups) indicating poorer neural recovery after rapid stimulation. A non-linearity evoked at longer interaction times (previously associated with parvocellular processing) with no evidence of contrast saturation and lower contrast gain showed no difference between autism quotient groups across the full range of stimulus contrasts. In addition, the short latency first order response and a small, early second order second slice response showed gain and semi-saturation parameters indicative of magnocellular origin, while the longer latency first order response probably reflects a mixture of inputs (including feedback from higher cortical areas). Significant motion coherence (AQ group) * (dot lifetime) interactions with higher coherence threshold for limited dot lifetime stimuli is consistent with atypical magnocellular functioning, however psychophysical performance for those with High AQ is not explained fully, suggesting that other factors may be involved.
