RESUMO

Historical structural racism in the built environment contributes to health inequities, yet to date, research has almost exclusively focused on racist policy of redlining. We expand upon this conceptualization of historical structural racism by examining the potential associations of probable blockbusting, urban renewal, and proximity to displacement from freeway construction, along with redlining, to multiple contemporary health measures. Analyses linked historical structural racism, measured continuously at the census-tract level using archival data sources, to present-day residents' physical health measures drawn from publicly accessible records for Allegheny County, Pennsylvania. Outcome measures included average life expectancy and the percentage of residents reporting hypertension, stroke, coronary heart disease, smoking, insufficient sleep, sedentary behavior, and no health insurance coverage. Multiple regression analyses were conducted to examine separate and additive associations between structural racism and physical health measures. Redlining, probable blockbusting, and urban renewal were associated with shorter life expectancy and a higher prevalence of cardiovascular conditions, risky health behaviors, and residents lacking health insurance coverage. Probable blockbusting and urban renewal had the most consistent correlations with all 8 health measures, while freeway displacement was not reliably associated with health. Additive models explained a greater proportion of variance in health than any individual structural racism measure alone. Moreover, probable blockbusting and urban renewal accounted for relatively more variance in health compared to redlining, suggesting that research should consider these other measures in addition to redlining. These preliminary correlational findings underscore the importance of considering multiple aspects of historical structural racism in relation to current health inequities and serve as a starting point for additional research.

RESUMO

BACKGROUND: Police activity in emergency medical settings has been shown to complicate the care of patients and impact patient-provider relationships. Recent scholarship has called for clear hospital policy outlining the terms of police access to patients and the role of clinicians. Despite regular contact between trauma surgeons and police, research on the impact of police activity on trauma care has been limited. METHODS: Semi-structured interviews were conducted with attending trauma surgeons and general surgery residents (N = 13) at 3 urban hospitals about their interactions with police in clinical settings. Participants were recruited using snowball sampling. Interviews were audio-recorded, transcribed, and analyzed for recurrent themes using an iterative grounded theory process. RESULTS: Participants reported routine contact with police that required active negotiation of the scope of clinical and police authority in the hospital. These negotiations were shaped by prior experiences, perceptions of police, officer behavior, and institutional culture. Surgeons felt compelled to advocate for patients, but reported intimidation in moments of conflict. Participants noted uncertainty around the legal dimensions of their relationship to police and a lack of universal guidance on appropriate responses. DISCUSSION: This data points to the need for improvements in both policy and workflow to regulate and reduce the burden of these interactions and protect clinicians' priorities from being subordinated to those of police. Further research is needed to understand how police presence impacts patient outcomes, and to guide best practices for regulating and mitigating potential negative impact.

RESUMO

Iron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.

RESUMO

OBJECTIVE: Childhood trauma may contribute to poor lifelong health in part through programming of the HPA-axis response to future life stressors. To date, empirical evidence shows an association of childhood trauma with dysregulation of the HPA-axis and blunted cortisol reactivity to acute stressors. Here, we conduct an initial examination of childhood trauma as a moderator of changes over time in perceived stress levels and HPA-axis response to a major chronic stressor in adulthood. METHODS: Participants were 83 maternal caregivers of children newly diagnosed with cancer who completed the Childhood Trauma Questionnaire (CTQ), and who, over the year following their child's cancer diagnosis, had hair samples collected up to 7 times for the assessment of cortisol and completed monthly measures of perceived stress. RESULTS: CTQ scores were in the expected range for a community sample and associated with changes in perceived stress and cortisol concentration over time (γ =.003, p =.002; γ = -.0004, p =.008, respectively) independently of age, education, treatment intensity and randomization to stress management intervention. Maternal caregivers who endorsed lower childhood trauma showed a steeper decline in perceived stress and a larger increase in cortisol levels across the year than caregivers who recalled more childhood trauma. CONCLUSIONS: Findings extend animal models and studies that examine cortisol reactivity to acute stressors and suggest that childhood trauma may program a phenotype that is more psychologically reactive but shows a blunted HPA-axis response to chronic stress. While adaptive in the short-term, this early life programming may incur long-term costs for health. Further work is warranted to examine this possibility.

RESUMO

BACKGROUND: Vaccination during pregnancy reduces the incidence of infections and their associated adverse outcomes in both mothers and infants. The American College of Obstetricians and Gynecologists has recommended influenza and Tdap vaccination during pregnancy since 2004 and 2013, respectively. Several studies have examined disparities in vaccination rates during pregnancy by race/ethnicity. However, none have included American Indians/Alaska Natives as a specific racial/ethnic group on a national level. Current literature suggests that American Indian/Alaska Native infants experience increased morbidity and mortality from both influenza and pertussis infections compared with most other groups in the United States. OBJECTIVE: This study aimed to evaluate the uptake of influenza and Tdap vaccinations during pregnancy by race/ethnicity, with a specific focus on American Indian/Alaska Native people. STUDY DESIGN: This cross-sectional study used data from the Pregnancy Risk Assessment Monitoring System. Comparisons of vaccine uptake across racial/ethnic groups (American Indian/Alaska Native, Asian, non-Hispanic Black, non-Hispanic White, Hispanic, and "None of the above") were evaluated using weighted logistic regression analyses to estimate prevalence odds ratios with 95% confidence intervals. Models were adjusted for maternal age, parity, maternal education, marital status, payment method at delivery, prenatal care in first trimester, maternal smoking status, Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation, and receipt of influenza vaccine reported by a health care provider. RESULTS: For both vaccines, Asian respondents had the highest uptake (influenza, 70.1%; Tdap, 68.2%), whereas Black respondents reported the lowest uptake (influenza, 44.4%; Tdap, 57.9%). For the influenza vaccine, American Indian/Alaska Native respondents demonstrated a higher uptake compared with White respondents, and the magnitude of difference increased markedly after adjusting for respondent characteristics (adjusted odds ratio, 1.74; 95% confidence interval, 1.58-1.90). In the unadjusted analyses, Black individuals reported influenza vaccination at approximately half the rate of their White counterparts during pregnancy. This effect was attenuated but remained lower after adjustment for respondent characteristics (adjusted odds ratio, 0.73; 95% confidence interval, 0.70-0.76). For the Tdap vaccine, American Indian/Alaska Native respondents reported lower uptake than White respondents; however, this difference disappeared when adjusted for respondent characteristics (adjusted odds ratio, 0.99; 95% confidence interval, 0.83-1.19). Asian and Hispanic respondents displayed a similar uptake compared with their White counterparts for both vaccines. CONCLUSION: Our findings indicate that there are racial/ethnic disparities in influenza and Tdap vaccination rates among pregnant individuals in the United States. Demonstration of increased uptake among American Indian/Alaska Native people in the crude analysis may reflect the success of various public health interventions through Tribal and Indian Health Service hospitals. Nonetheless, vaccination status during pregnancy remains seriously below national guideline recommendations. Greater measures must be taken to support preventative care in marginalized populations, with particular emphasis on community-driven solutions rooted in justice.

RESUMO

PURPOSE: To determine the most common indications for lateral extra-articular tenodesis (LET) augmentation of anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic review of the literature was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched PubMed, Embase, Web of Science, and Cochrane Database of Systematic Reviews from 2000 to the present (June 2022). Studies that met the following criteria were included: patients of any age who underwent LET in addition to ACLR, studies reporting at least 1 indication for LET, and observational/randomized controlled trial study designs including prevalence of indications. Publications had to be reported in English and peer reviewed and to have originated in the United States or countries offering identical protocols and procedures. RESULTS: A total of 463 studies were identified from the initial search, 23 of which met inclusion criteria and were included in the review. Eight of the 23 studies (34.8%) used a modified Lemaire technique, seven (30.4%) used a MacIntosh modified by Arnold-Coker, and eight (34.8%) used other techniques to perform LET. A total of 2,125 patients (53% female, 47% male [3 studies did not report sex]) underwent ACLR augmented with LET. The indications along with prevalence were as follows: positive pivot shift test (grade ≥2) (19 of 23, 82.6%), revision ACLR (12 of 23, 52.2%), ligamentous laxity (11 of 23, 47.8%), general sports participation (11 of 23, 47.8%), age less than 25 years (8 of 23, 34.8%), high risk of graft failure (5 of 23, 21.7%), and positive Lachman test (4 of 23, 17.4%). CONCLUSIONS: Pivot shift grade ≥2 was the most common reason orthopaedic surgeons chose to add LET to ACLR, with revision ACLR, patient age <25, and general sports participation following closely behind. LEVEL OF EVIDENCE: Level I to IV, systematic review of studies.

RESUMO

AIM: To characterize early changes in developmental ability, language, and adaptive behaviour in infants diagnosed with tuberous sclerosis complex (TSC), and determine whether clinical features of epilepsy influence this pathway. METHOD: Prospective, longitudinal data were collected within the Early Development in Tuberous Sclerosis (EDiTS) Study to track development of infants with TSC (n = 32) and typically developing infants (n = 33) between 3 and 24 months of age. Questionnaire and observational measures were used at up to seven timepoints to assess infants' adaptive behaviour, developmental ability, language, and epilepsy. RESULTS: A significant group by age interaction effect showed that infants with TSC had lower adaptive functioning at 18 to 24 months old (intercept = 88.12, slope estimate = -0.82, p < 0.001) and lower developmental ability scores from 10 months old (intercept = 83.33, slope estimate = -1.44, p < 0.001) compared to typically developing infants. Early epilepsy severity was a significant predictor of these emerging developmental (R2 = 0.35, p = 0.004, 95% confidence interval [CI] -0.08 to -0.01) and adaptive behaviour delays (R2 = 0.34, p = 0.004, 95% CI -0.05 to -0.01]). Lower vocabulary production (intercept = -1.25, slope = -0.12, p < 0.001) and comprehension scores (intercept = 2.39, slope estimate = -0.05, p < 0.001) in infants with TSC at 24 months old were not associated with epilepsy severity. INTERPRETATION: Divergence of developmental ability and adaptive functioning skills occur in infants with TSC from 10 and 18 months, respectively. Associations between early epilepsy severity and impaired development supports the importance of early intervention to reduce seizure severity.

RESUMO

Despite the large number of microfluidic devices that have been described over the past decade for the study of tissues and organs, few have become widely adopted. There are many reasons for this lack of adoption, primarily that devices are constructed for a single purpose or because they are highly complex and require relatively expensive investment in facilities and training. Here, we describe a microphysiological system (MPS) that is simple to use and provides fluid channels above and below cells, or tissue biopsies, maintained on a disposable, poly(methyl methacrylate), carrier held between polycarbonate outer plates. All other fittings are standard Luer sizes for ease of adoption. The carrier can be coated with cells on both sides to generate membrane barriers, and the devices can be established in series to allow medium to flow from one cell layer to another. Furthermore, the carrier containing cells can be easily removed after treatment on the device and the cells can be visualized or recovered for additional off-chip analysis. A 0.4 µm membrane with cell monolayers proved most effective in maintaining separate fluid flows, allowing apical and basal surfaces to be perfused independently. A panel of different cell lines (Caco-2, HT29-MTX-E12, SH-SY5Y, and HUVEC) were successfully maintained in the MPS for up to 7 days, either alone or on devices connected in series. The presence of tight junctions and mucin was expressed as expected by Caco-2 and HT-29-MTX-E12, with Concanavalin A showing uniform staining. Addition of Annexin V and PI showed viability of these cells to be >80% at 7 days. Bacterial extracellular vesicles (BEVs) produced by Bacteroides thetaiotaomicron and labeled with 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbo-cyanine perchlorate (DiD) were used as a model component of the human colonic microbiota and were visualized translocating from an apical surface containing Caco-2 cells to differentiated SH-SY5Y neuronal cells cultured on the basal surface of connected devices. The newly described MPS can be easily adapted, by changing the carrier to maintain spheroids, pieces, or slices of biopsy tissue and joined in series to study a variety of cell and tissue processes. The cell layers can be made more complex through the addition of multiple cell types and/or different patterning of extracellular matrix and the ability to culture cells adjacent to one another to allow study of cell:cell transfer, e.g., passive or active drug transfer, virus or bacterial entry or BEV uptake and transfer.

RESUMO

Background: Idiopathic Multicentric Castleman Disease (iMCD) is a rare inflammatory lymphoproliferative disorder with heterogenous clinical presentations. The symptomatology in iMCD patients remains poorly understood. The aim of this study was to identify the type, frequency and severity of iMCD-related symptoms and the impact of these on the daily lives of iMCD patients and informal-caregivers. Methods: We conducted two bespoke 45-question online surveys for iMCD patients and informal-caregivers of patients recruited from the US, UK, Australia and Canada between April 14 and November 8, 2021. Descriptive data was collected, and a Likert scale was used to quantify the impact of symptoms on various aspects of daily life. Ordinal logistic regression analysis was used to determine associations between age, gender, employment status and symptom burden with aspects of daily life. Findings: Eligible respondents included 51 iMCD patients and 11 informal-caregivers. Patients reported up to 27 unique symptoms, the mean number of symptoms experienced by a patient was 6.7 (range 0-22 symptoms). Most symptoms had a moderate to severe impact on patients' daily lives, with 'pain/discomfort', 'ability to travel', and 'sexual functioning' being the most impacted. iMCD patient characteristics such as being 40 years or older, female, and either disabled or unemployed was significantly associated with adverse impact on several aspects of daily life. Among caregivers, the aspects of daily life that were disproportionately affected was their own social life and freedom, emotional wellbeing, travel/relocation, and work. Interpretation: iMCD patients have widely varied and unappreciated symptomatology. High symptom burden adversely impacts several aspects of patient daily lives as well as their caregivers. Funding: Funding was provided by EUSA Pharma.

RESUMO

BACKGROUND: Subjective social status (SSS) refers to a person's perception of their social rank relative to others and is cross-sectionally linked to systemic inflammation independently of objective socioeconomic status. PURPOSE: We test the extent to which SSS relates to multiyear changes in inflammation, or if associations differ by race or sex. METHODS: Healthy adults (N = 331; 30-51 years) completed a baseline visit and 278 participants returned for a second visit 2.85 years later. At both visits, participants underwent a fasting blood draw and completed community (SSSC) and US (SSSUS) versions of the MacArthur Scale. Multiple linear regression analyses examined change in interleukin-6 (IL-6) and C-reactive protein (CRP) predicted by each type of SSS, adjusting for time between visits, sex, race, age, body mass index, smoking, baseline inflammation, and objective socioeconomic status. Additional analyses further adjusted for hopelessness and depressive symptoms. Interactions examined moderations by sex and race. RESULTS: Lower SSSC was longitudinally associated with greater IL-6 independently of all covariates, including education and income (ß = -0.06), hopelessness (ß = -0.06), and depressive symptoms (ß = -0.06). Lower SSSUS was longitudinally associated with greater IL-6 independently of demographic covariates including education and income (ß = -0.06), but was slightly attenuated after adjusting for hopelessness (ß = -0.06) and depressive symptoms (ß = -0.06). There were no associations for CRP or moderation by race or sex. CONCLUSIONS: Lower SSS may be associated with greater circulating markers of inflammation over time as suggested by increases in IL-6.


Subjective social status (SSS) refers to how people perceive their social rank compared with others and has been linked to meaningful differences in physical health. Increases in inflammation may contribute to associations between lower SSS and poorer physical health. In a sample of healthy adults, we examined whether SSS was associated with prospective, multiyear changes in markers of systemic inflammation and if this differed by sex or race. We found that adults who perceived their social status as lower than peers in their community exhibited an accelerated increase in interleukin-6, a marker of systemic inflammation, over a 3-year period. When participants were asked to compare themselves to people in the broader USA, the pattern was similar but less robust. Results were independent of individual differences in sociodemographic characteristics including family-adjusted income and education. Findings did not differ by sex or race and were not explained by differences in adiposity and symptoms of depression and hopelessness. Effects for C-reactive protein, a second marker of inflammation, were generally nonsignificant. Although preliminary, findings suggest an immune pathway by which perceived social status may relate to chronic diseases of aging.

RESUMO

Despite widespread evidence suggesting that e-cigarettes are harmful to youth, the prevalence of adolescent vaping continues to rise. The first aim of this cross-sectional study was to determine which methods adolescents have previously used to quit vaping and their interest in using various methods to quit vaping in the future. The second aim was to investigate the associations between vaping-related characteristics and (1) motivation to quit vaping and (2) previous use of pharmacological methods to quit vaping or previous use of unassisted quitting. Participants were 185 current or former vapers, aged 14-19 (M age = 16.9 years, SD = 1.1; 52% female), recruited online from different U.S. regions. Data were collected through online questionnaires. Most participants reported at least one prior attempt to quit vaping (81.3%). Unassisted quitting was the most prevalent method to quit vaping (78.4%), followed by "advice from a friend" (51.9%). Participants were interested in using a variety of methods for quitting vaping in the future, including medication (28.8%), and mobile apps (34.6%). Greater perceived harm of vaping was significantly associated with motivation to quit vaping, while greater perceived risk of addiction and higher SES were significantly associated with lifetimeuse of nicotine replacement to quit vaping. Adolescents may be open to trying methods to quit that are different from what they have used previously. These findings could help direct resources toward the development of vaping cessation programs that are acceptable to adolescents.

RESUMO

Macroautophagy/autophagy occurs basally under nutrient-rich conditions in most mammalian cells, contributing to protein and organelle quality control, and protection against aging and neurodegeneration. During autophagy, lysosomes are heavily utilized via their fusion with autophagosomes and must be repopulated to maintain autophagic degradative capacity. During starvation-induced autophagy, lysosomes are generated via de novo biogenesis under the control of TFEB (transcription factor EB), or by the recycling of autolysosome membranes via autophagic lysosome reformation (ALR). However, these lysosome repopulation processes do not operate under nutrient-rich conditions. In our recent study, we identify a sequential phosphoinositide conversion pathway that enables lysosome repopulation under nutrient-rich conditions to facilitate basal autophagy. Phosphatidylinositol-3,4-bisphosphate (PtdIns[3,4]P2) signals generated downstream of phosphoinositide 3-kinase alpha (PI3Kα) during growth factor stimulation are converted to phosphatidylinositol-3-phosphate (PtdIns3P) on endosomes by INPP4B (inositol polyphosphate-4-phosphatase type II B). We show that PtdIns3P is retained as endosomes mature into endolysosomes, and serves as a substrate for PIKFYVE (phosphoinositide kinase, FYVE-type zinc finger containing) to generate phosphatidylinositol-3,5-bisphosphate (PtdIns[3,5]P2) to promote SNX2-dependent lysosome reformation, basal autophagic flux and protein aggregate degradation. Therefore, endosome maturation couples nutrient signaling to lysosome repopulation during basal autophagy by delivering PI3Kα-derived PtdIns3P to endolysosomes for PtdIns(3,5)P2-dependent lysosome reformation.Abbreviations: ALR: autophagic lysosome reformation; INPP4B: inositol polyphosphate-4-phosphatase type II B; PI3Kα: phosphoinositide 3-kinase alpha; PIKFYVE: phosphoinositide kinase FYVE-type zinc finger containing; PtdIns3P: phosphatidylinositol-3-phosphate; PtdIns(3,4)P2: phosphatidylinositol-3,4-bisphosphate; PtdIns(3,5)P2 phosphatidylinositol-3,5-bisphosphate; SNX2 sorting nexin 2; PIK3C3/VPS34 phosphatidylinositol 3-kinase catalytic subunit type 3.

RESUMO

Childhood trauma may confer risk for poorer adult health through changes in systemic inflammation. Emotion regulation may plausibly moderate associations between childhood trauma and adult psychological well-being, but it remains unclear whether moderation effects extend to differences in systemic inflammation. To examine whether childhood trauma and emotion regulation separately and interactively predict prospective changes in C-reactive protein (CRP) and interleukin-6 (IL-6) and whether biopsychosocial factors account for observed associations. Healthy midlife adults (N = 331) retrospectively reported on childhood trauma, current trait-level cognitive reappraisal and expressive suppression, and had their blood drawn. At baseline and then a median of 2.85 years later, 279 of the 331 participants had their blood drawn, body mass index calculated, and reported on health behaviours (smoking, sleep), psychological distress (perceived stress, depressive symptoms), and years of education. Childhood trauma predicted prospective increases in CRP (B = 0.004, p = 0.049), which were partially accounted for by differences in adiposity, psychological distress, and health behaviours. In contrast, cognitive reappraisal predicted prospective decreases in IL-6 (B = -0.007, p = 0.006), which were independent of biopsychosocial influences. Cognitive reappraisal further moderated the association between childhood trauma and prospective changes in IL-6 (B = -0.001, p = 0.012) such that childhood trauma predicted greater IL-6 increases but only among adults lower in cognitive reappraisal (B = 0.006, p = 0.007). There were no main or moderation effects of expressive suppression (ps > 0.05). Cognitive reappraisal may attenuate IL-6 changes over time and may moderate the prospective association between childhood trauma and systemic inflammation in midlife.

RESUMO

Adjuvant chemotherapy of leucovorin-modulated 5-fluorouracil (5-FU/LV), capecitabine, and adding oxaliplatin to 5-FU/LV or capecitabine (FLOX/OX) have been standard regimens for high-risk stage II or III colon cancer (CC). We aimed to evaluate their patterns of use, association with survival, and rate of emergency room visit (ER) or hospitalization during the treatment period. High-risk stage II or III patients aged >65 years diagnosed between 2007 and 2015, underwent colectomy, and received any of these three regimens were selected from SEER and Texas Cancer Registry (TC) linked with Medicare data. Chi-square test, Kaplan-Meier survival curves, Cox regression, and logistic regression were used in data analysis. A total of 5621 (1080 stage II and 4541 stage III) patients with median age of 72 years were included in this study. For stage II, 24.4% used 5-FU/LV, 31.2% used capecitabine, and 44.4% used FLOX/OX; the respective numbers for stage III were 13.8%, 17.9%, and 68.3%. Patients aged <70 years, not in the West region, not in Medicare state-buy-in program, and with no comorbidity were more likely to use FLOX/OX. FLOX/OX was associated with improved overall survival (OS) in stage II and III patients and improved cancer-specific survival in stage III patients compared with 5-FU/LV. The survival benefit of FLOX/OX was sustained in stage III patients aged ≥70 years. Capecitabine had the lowest ER/hospitalization rate with 19.2% in stage II and 28.9% in III. The use of FLOX/OX was associated with improved survival compared with 5-FU/LV among CC patients. Capecitabine was associated with the lowest ER/hospitalization rate.

RESUMO

PURPOSE: To examine whether emotional support moderates the association between college generation status and concurrent and prospective levels of systemic inflammation during the college transition among a sample of older U.S. adolescents. METHODS: At an undergraduate tertiary institution, 41 first-generation college students (first-gens) and 46 continuing-generation college students (continuing-gens) in their first semester of college reported on basic demographic information and perceived emotional support. They also had their blood drawn midway through both the first and second semester to measure C-reactive protein and interleukin-6. An inflammatory composite for each semester was created by averaging the standardized scores for log-transformed C-reactive protein and interleukin-6. RESULTS: Compared to continuing-gens, first-gens had greater systemic inflammation in the first semester regardless of their level of emotional support (B = 0.515, p = .003). However, emotional support moderated the association between college generation status and prospective systemic inflammation in the second semester (B = -0.525, p = .007) such that first-gens had greater systemic inflammation compared to continuing-gens, but only if they reported lower levels of emotional support (B = 0.826, p = .002). This moderation effect held after further adjusting for systemic inflammation in the first semester (B = -0.374, p = .022). Also discussed are results of secondary analyses examining sources of support. DISCUSSION: Compared to continuing-gens, first-gens had greater systemic inflammation in the first semester irrespective of emotional support, suggesting all first-gens may stand to benefit from college resources provided early in the college transition. Furthermore, first-gens who reported lower levels of emotional support may benefit from additional college resources provided beyond the first semester.

RESUMO

BACKGROUND: Autism is proposed to be characterised by an atypical balance of cortical excitation and inhibition (E/I). However, most studies have examined E/I alterations in older autistic individuals, meaning that findings could in part reflect homeostatic compensation. To assess the directionality of effects, it is necessary to examine alterations in E/I balance early in the lifespan before symptom emergence. Recent explanatory frameworks have argued that it is also necessary to consider how early risk features interact with later developing modifier factors to predict autism outcomes. METHOD: We indexed E/I balance in early infancy by extracting the aperiodic exponent of the slope of the electroencephalogram (EEG) power spectrum ('1/f'). To validate our index of E/I balance, we tested for differences in the aperiodic exponent in 10-month-old infants with (n = 22) and without (n = 27) neurofibromatosis type 1 (NF1), a condition thought to be characterised by alterations to cortical inhibition. We then tested for E/I alterations in a larger heterogeneous longitudinal cohort of infants with and without a family history of neurodevelopmental conditions (n = 150) who had been followed to early childhood. We tested the relevance of alterations in E/I balance and our proposed modifier, executive attention, by assessing whether associations between 10-month aperiodic slope and 36-month neurodevelopmental traits were moderated by 24-month executive attention. Analyses adjusted for age at EEG assessment, sex and number of EEG trials. RESULTS: Infants with NF1 were characterised by a higher aperiodic exponent, indicative of greater inhibition, supporting our infant measure of E/I. Longitudinal analyses showed a significant interaction between aperiodic slope and executive attention, such that higher aperiodic exponents predicted greater autistic traits in childhood, but only in infants who also had weaker executive functioning abilities. LIMITATIONS: The current study relied on parent report of infant executive functioning-type abilities; future work is required to replicate effects with objective measures of cognition. CONCLUSIONS: Results suggest alterations in E/I balance are on the developmental pathway to autism outcomes, and that higher executive functioning abilities may buffer the impact of early cortical atypicalities, consistent with proposals that stronger executive functioning abilities may modify the impact of a wide range of risk factors.
