Racial, ethnic, and socioeconomic disparities persist in posttraumatic stress disorder (PTSD), which are partly attributed to minoritized women being trauma-exposed, while also contending with harmful contextual stressors. However, few have used analytic strategies that capture the interplay of these experiences and their relation to PTSD. The current study used a person-centered statistical approach to examine heterogeneity in trauma and contextual stress exposure, and their associations with PTSD and underlying symptom dimensions, in a diverse sample of low-income postpartum women.

Using a community-based sample of Black, Hispanic/Latina, and White postpartum women recruited from five U.S. regions (n = 1577), a latent class analysis generated profiles of past-year exposure to traumatic events and contextual stress at one month postpartum. Regression analyses then examined associations between class membership and PTSD symptom severity at six months postpartum as a function of race/ethnicity.

A four-class solution best fit the data, yielding High Contextual Stress, Injury/Illness, Violence Exposure, and Low Trauma/Contextual Stress classes. Compared to the Low Trauma/Contextual Stress class, membership in any of the other classes was associated with greater symptom severity across nearly all PTSD symptom dimensions (all ps < 0.05). Additionally, constellations of exposures were differentially linked to total PTSD symptom severity, reexperiencing, and numbing PTSD symptoms across racial/ethnic groups (ps < 0.05).

A person-centered approach to trauma and contextual stress exposure can capture heterogeneity of experiences in diverse, low-income women. Moreover, racially/ethnically patterned links between traumatic or stressful exposures and PTSD symptom dimensions have implications for screening and intervention in the perinatal period.

In ESCAPE-TRD (NCT04338321), a randomized, open-label, rater-blinded, long-term, phase 3b trial, augmentation with esketamine nasal spray (ESK) demonstrated increased probability of achieving meaningful clinical benefit versus quetiapine extended release (QUE XR) in patients (pts) with treatment-resistant depression (TRD). This subgroup analysis of ESCAPE-TRD evaluated the incidence, duration, and impact of treatment-emergent adverse events (TEAEs) on treatment discontinuation in adults with TRD treated with ESK or QUE XR according to US prescribing information.

Pts aged 18-64 years were randomly assigned to receive flexibly dosed ESK (56 or 84 mg) or QUE XR (150-300 mg), both consistent with US label dosing and in combination with an ongoing oral antidepressant. The incidence and duration of the most commonly occurring TEAEs, as well as the most common TEAEs leading to treatment discontinuation, were summarized descriptively. All randomly assigned participants receiving ≥1 dose of study drug were included in the safety analyses.

Among the 636 pts included in the subgroup analysis, 316 and 320 were randomly assigned to ESK and QUE XR, respectively; 314 and 316 were included in the safety population. In the combined acute and maintenance phases, TEAEs occurred in 92.0% of pts in the ESK group and 78.5% of pts in the QUE XR group. The most commonly reported TEAEs with ESK or QUE XR in the combined acute and maintenance phases were dizziness (47.1% and 7.9%, respectively), headache (25.5% and 13.0%, respectively), somnolence (15.0% and 23.4%, respectively), and nausea (29.9% and 3.2%, respectively). Across all TEAE events reported in >5% of pts in either arm, 91.8% (5831 of 6351) resolved within 1 day in the ESK arm compared to 11.6% (90 of 776) with QUE XR. For specific TEAE events of clinical interest for ESK, same-day resolution rates for increased blood pressure, sedation, and dissociation in the ESK group were 93.5% (116 of 124), 96.2% (127 of 132), and 99.6% (740 of 743), respectively. The majority of TEAEs of clinical interest in the ESK group that occurred on the same day of dosing resolved within the first 2 hours after dosing. For the most frequently reported TEAEs with QUE XR, same-day resolution rates for somnolence, headache, and fatigue were 7.8% (8 of 103), 49.2% (29 of 59), and 9.5% (4 of 42), respectively. Fewer pts treated with ESK discontinued treatment due to TEAEs compared to QUE XR (4.4% versus 10.6%).

Safety data from this subgroup analysis were consistent with the overall study population as well as the known tolerability profile of each treatment. TEAEs were reported at higher incidence with ESK than with QUE XR; however, the majority of TEAEs occurring with ESK were transient in nature and did not result in a higher rate of treatment discontinuation compared to QUE XR.

To understand the characteristics of food environments in the Pacific region, and the broader economic, policy and sociocultural surroundings that influence food choices and interventions to improve food environments for Pacific communities.

Systematic searches were conducted for articles related to food environments or factors influencing food choices from 1993 to 2024 in five academic databases, Google, Google Scholar and relevant organisations’ websites. Studies were included if they meet the eligibility criteria. Two authors independently reviewed the title and abstract of identified articles. Full-text screening was conducted before data were extracted from eligible studies. A narrative analysis was informed by an existing food environments framework.

Pacific Island countries or territories that are a member of the Pacific Community (SPC).

From the sixty-six included studies (of 2520 records screened), it was clear that food environments in the Pacific region are characterised by high availability and promotion of ultra-processed unhealthy foods. These foods were reported to be cheaper than healthier alternatives and have poor nutritional labelling. Food trade and investment, together with sociocultural and political factors, were found to contribute to unhealthy food choices. Policy interventions have been implemented to address food environments; however, the development and implementation of food environment policies could be strengthened through stronger leadership, effective multisectoral collaboration and clear lines of responsibility.

Interventions focused on improving physical, economic, policy and sociocultural influences on food choices should be prioritised in the Pacific region to improve the food environment and mitigate barriers to healthy eating.

Children with left aortic arch and aberrant right subclavian artery may present with either respiratory or swallowing symptoms beyond the classically described solid-food dysphagia. We describe the clinical features and outcomes of children undergoing surgical repair of an aberrant right subclavian artery.

This was a retrospective review of children undergoing repair of an aberrant right subclavian artery between 2017 and 2022. Primary outcome was symptom improvement. Pre- and post-operative questionnaires were used to assess dysphagia (PEDI-EAT-10) and respiratory symptoms (PEDI-TBM-7). Paired t-test and Fisher’s exact test were used to analyse symptom resolution. Secondary outcomes included perioperative outcomes, complications, and length of stay.

Twenty children, median age 2 years (IQR 1–11), were included. All presented with swallowing symptoms, and 14 (70%) also experienced respiratory symptoms. Statistically significant improvements in symptoms were reported for both respiratory and swallowing symptoms. Paired (pre- and post-op) PEDI-EAT-10 and PEDI-TBM-7 scores were obtained for nine patients, resulting in mean (± SD) scores decreasing (improvement in symptoms) from 19.9 (± 9.3) to 2.4 (± 2.5) p = 0.001, and 8.7 (± 4.7) to 2.8 (± 4.0) p = 0.006, respectively. Reoperation was required in one patient due to persistent dysphagia from an oesophageal stricture. Other complications included lymphatic drainage (n = 4) and transient left vocal cord hypomobility (n = 1).

Children with a left aortic arch with aberrant right subclavian artery can present with oesophageal and respiratory symptoms beyond solid food dysphagia. A thorough multidisciplinary evaluation is imperative to identify patients who can benefit from surgical repair, which appears to be safe and effective.

Leveraging the National COVID-19 Cohort Collaborative (N3C), a nationally sampled electronic health records repository, we explored associations between individual-level social determinants of health (SDoH) and COVID-19-related hospitalizations among racialized minority people with human immunodeficiency virus (HIV) (PWH), who have been historically adversely affected by SDoH.

We retrospectively studied PWH and people without HIV (PWoH) using N3C data from January 2020 to November 2023. We evaluated SDoH variables across three domains in the Healthy People 2030 framework: (1) healthcare access, (2) economic stability, and (3) social cohesion with our primary outcome, COVID-19-related hospitalization. We conducted hierarchically nested additive and adjusted mixed-effects logistic regression models, stratifying by HIV status and race/ethnicity groups, accounting for age, sex, comorbidities, and data partners.

Our analytic sample included 280,441 individuals from 24 data partner sites, where 3,291 (1.17%) were PWH, with racialized minority PWH having higher proportions of adverse SDoH exposures than racialized minority PWoH. COVID-19-related hospitalizations occurred in 11.23% of all individuals (9.17% among PWH, 11.26% among PWoH). In our initial additive modeling, we observed that all three SDoH domains were significantly associated with hospitalizations, even with progressive adjustments (adjusted odds ratios [aOR] range 1.36–1.97). Subsequently, our HIV-stratified analyses indicated economic instability was associated with hospitalization in both PWH and PWoH (aOR range 1.35–1.48). Lastly, our fully adjusted, race/ethnicity-stratified analysis, indicated access to healthcare issues was associated with hospitalization across various racialized groups (aOR range 1.36–2.00).

Our study underscores the importance of assessing individual-level SDoH variables to unravel the complex interplay of these factors for racialized minority groups.

The 2022 SHEA/IDSA/APIC guidance for surgical site infection (SSI) prevention recommends reserving vancomycin prophylaxis to patients who are methicillin-resistant Staphylococcus aureus (MRSA) colonized. Unfortunately, vancomycin prophylaxis remains common due to the overestimation of MRSA risk and the desire to cover MRSA in patients with certain healthcare-associated characteristics. To optimize vancomycin prophylaxis, we sought to identify risk factors for MRSA SSI.

This was a single-center, case-control study of patients with a postoperative SSI after undergoing a National Healthcare Safety Network operative procedure over eight years. MRSA SSI cases were compared to non-MRSA SSI controls. Forty-two demographic, medical, and surgical characteristics were evaluated.

Of the 441 patients included, 23 developed MRSA SSIs (rate = 5.2 per 100 SSIs). In the multivariable model, we identified two independent risk factors for MRSA SSI: a history of MRSA colonization or infection (OR, 9.0 [95% CI, 1.9–29.6]) and hip or knee replacement surgery (OR, 3.8 [95% CI, 1.3–9.9]). Hemodialysis, previous hospitalization, and prolonged hospitalization prior to the procedure had no measurable association with odds of MRSA SSI.

Patients with prior MRSA colonization or infection had 9–10 times greater odds of MRSA SSI and patients undergoing hip and knee replacement had 3–4 times greater odds of MRSA SSI. Healthcare-associated characteristics, such as previous hospitalization or hemodialysis, were not associated with MRSA SSI. Our findings support national recommendations to reserve vancomycin prophylaxis for patients who are MRSA colonized, as well as those undergoing hip and knee replacement, in the absence of routine MRSA colonization surveillance.

To determine the effects of the non-classic psychedelic, ibogaine, on cognitive functioning. Ibogaine is an indole alkaloid derived from the Tabernanthe Iboga plant family, indigenous to Africa, and traditionally used in spiritual and healing ceremonies. Ibogaine has primarily been studied with respect to its clinical efficacy in reducing substance addiction. There are, however, indications that it also may enhance recovery from traumatic experiences. Ibogaine is a Schedule 1 substance in the USA.

Participants were U.S. Special Operations Veterans who had independently and voluntarily referred themselves for an ibogaine retreat at a specialized clinic outside the USA prior to learning about this observational study. After meeting rigorous screening requirements, 30 participants were enrolled, all endorsing histories of combat and repeated blast exposure, as well as traumatic brain injury. Participants were seen in person pre-treatment, post-treatment, and one-month post-treatment for neuropsychological testing, neuroimaging, and collection of clinical outcome measures. All 30 participants were seen pre- and post-treatment, of whom 27 were also able to return one-month post-treatment.

The neuropsychological battery included the the Hopkins Verbal Learning Test (HVLT), the Brief Visuospatial Memory Test - Revised (BVMT-R), the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) Working Memory Index (Digit Span and Arithmetic) and Processing Speed Index (Symbol Search and Coding), and the Delis-Kaplan Executive Function System (D-KEFS) tests of Verbal Fluency (VF), Trail Making (TMT), Color Word (CW), and Tower Test (TT). For repeated measures, alternate forms were used whenever possible.

Repeated-measures ANOVA revealed significant effects of time, with post-treatment improvements across multiple measures including processing speed (WAIS-IV PSI; F(2,25) = 26.957, p < .001), executive functions (CW Conditions 3 and 4: F(1.445,25) = 11.383, p < .001 and F(1.381,25) = 7.687, p = .004, respectively), verbal fluency (VF Condition 3 correct and accuracy: F(2,25) = 6.419, p = .003 and F(2,25) = 153.076, p < .001, respectively), and verbal learning (HVLT Total Recall (alternate forms used at each time point): F(1.563,23) = 6.958, p = .004). Score progression graphs are presented. Performance on all other cognitive measures did not significantly change following treatment.

To our knowledge, this is the first prospective study examining neuropsychological test performance following ibogaine use at post-treatment and one-month post-treatment time points. Our results indicated that several cognitive domains improved either post-treatment or one-month post-ibogaine treatment, suggesting ibogaine’s therapeutic potential for cognition in the context of traumatic brain injury and mood disorders. Potential explanations include neuroplastic changes, reduction of PTSD and mood-related effects on cognitive functioning, and practice effects. While we found no evidence of negative cognitive consequences for up to one-month post-single-ibogaine treatment, further study of this substance is necessary to clarify its clinical utility and safety parameters.

Attention is the backbone of cognitive systems and is requisite for many cognitive processes vital to everyday functioning, including memory, problem solving, and the cognitive control of behavior. Attention is commonly impaired following traumatic brain injury and is a critical focus of rehabilitation efforts. The development of reliable methods to assess rehabilitation-related changes are paramount. The Attention Network Test (ANT) has been used previously to identify 3 independent, yet interactive attention networks—alerting, orienting, and executive control (EC). We examined the behavioral and neurophysiological robustness and temporal stability of these networks across multiple sessions to assess the ANT’s potential utility as an effective measure of change during attention rehabilitative interventions.

15 healthy young adults completed 4 sessions of the ANT (1 session/7-day period). ANT networks were assessed within the task by contrasting opposing stimulus conditions: cued vs. non-cued trials probed alerting, valid vs. invalid spatial cues probed orienting, and congruent vs. incongruent targets probed EC. Differences in median correct-trial reaction times (RTs) and error rates (ERs) between the condition pairs were assessed to determine attention network scores; robustness of networks effects, as determined by one-sample t-tests at each session, against a mean of 0, determining the presence of significant network effects at each session. Sixty-four-channel electroencephalography (EEG) data were acquired concurrently and processed using Matlab to create condition-related event-related potentials (ERPs)—particularly the cue- and probe-related P1, N1, and P3 deflection amplitudes, measured by using signed-area calculation in regions of interest (ROIs) determined by observation of spherical-spline voltages. This enabled us to examine the robustness of cue- and probe-attention-network ERPs.

All three attention networks showed robust effects. However, only the EC RT and ER network scores remained significantly robust [t(14)s>13.9,ps<.001] across all sessions, indicating that EC is robust in the face of repeated exposure. Session 1 showed the greatest EC-RT robustness effect which became smaller during the subsequent sessions per ANOVAs on Session x Congruency [F(3,42)=10.21,p<.0001], reflecting persistence despite practice effects. RT robustness of the other networks varied across sessions. Alerting and EC ERs were similarly robust across all 4 sessions, but were more variable for the orienting network. ERP results: The cue-locked P1-orienting (valid vs. invalid) was generally larger to valid- than invalid-cues, but the robustness across sessions was variable (significant in only sessions 1 and 4 [t(14)s>2.13,ps<.04], as reflected in a significant main effect of session [p=.0042]. Next, target-locked EC P3s were generally smaller to congruent than incongruent targets [F(1,14)=9.40,p=.0084], showing robust effects only in sessions 3 and 4 [ps<.005].

The EC network RT and ER scores were consistently robust across all sessions, suggesting that this network may be less vulnerable to practice effects across session than the other networks and may be the most reliable probe of attentional rehabilitation. ERP measures were more variable across attention networks with respect to robustness. Behavioral measures of EC-network may be most reliable for assessing progress related to attentional-rehabilitation efforts.

To evaluate the impact of a menu box delivery service tailored to the long-day care (LDC) setting on improving menu compliance with recommendations, children’s diet quality and dietary intake while in care.

A cluster randomised controlled trial in LDC centres randomly assigned to an intervention (menu box delivery) or comparison (menu planning training) group. The primary outcome was child food provision and dietary intake. Secondary outcomes include menu compliance and process evaluation, including acceptability, fidelity and menu cost (per child, per day).

South Australian LDC centres.

Eight LDC centres (n 224 children) provided data.

No differences were observed in serves/d between intervention and comparison centres, for provision (intervention, 0·9 inter-quartile range (IQR) 0·7–1·2; comparison, 0·8 IQR 0·5–1·3) or consumption (intervention, 0·5 IQR 0·2–0·8; comparison, 0·5 IQR 0·3–0·9) of vegetables. Child food provision and dietary intake were similar across both groups for all food groups (P < 0·05). At follow-up, all intervention centres met menu planning guidelines for vegetables, whereas only one comparison centre met guidelines. Intervention centre directors found the menu box delivery more acceptable than cooks. Cost of the intervention was AUD$2·34 greater than comparison centres (intervention, AUD$4·62 (95 % CI ($4·58, $4·67)); comparison, AUD$2·28 (95 % CI ($2·27, $2·30)) per child, per day).

Menu compliance can be improved via a menu delivery service, delivering equivalent impacts on child food provision and dietary intake compared with an online training programme. Further exploration of cooks acceptability and cost is essential before scaling up to implementation.

Cross-sectional studies have shown that the COVID-19 pandemic has had a significant impact on the mental health of healthcare staff. However, it is less well understood how working over the long term in successive COVID-19 waves affects staff well-being.

To identify subpopulations within the health and social care staff workforce with differentiated trajectories of mental health symptoms during phases of the COVID-19 pandemic.

The COVID-19 Staff Wellbeing Survey assessed health and social care staff well-being within an area of the UK at four time points, separated by 3-month intervals, spanning November 2020 to August 2021.

Growth mixture models were performed on the depression, anxiety and post-traumatic stress disorder longitudinal data. Two class solutions provided the best fit for all models. The vast majority of the workforce were best represented by the low-symptom class trajectory, where by symptoms were consistently below the clinical cut-off for moderate-to-severe symptoms. A sizable minority (13–16%) were categorised as being in the high-symptom class, a group who had symptom levels in the moderate-to-severe range throughout the peaks and troughs of the pandemic. In the depression, anxiety and post-traumatic stress disorder models, the high-symptom class perceived communication from their organisation to be less effective than the low-symptom class.

This research identified a group of health service staff who reported persistently high mental health symptoms during the pandemic. This group of staff may well have particular needs in terms of the provision of well-being support services.

Limitations of traditional geospatial measures, like the modified Retail Food Environment Index (mRFEI), are well documented. In response, we aimed to: (1) extend existing food environment measures by inductively developing subcategories to increase the granularity of healthy v. less healthy food retailers; (2) establish replicable coding processes and procedures; and (3) demonstrate how a food retailer codebook and database can be used in healthy public policy advocacy.

We expanded the mRFEI measure such that ‘healthy’ food retailers included grocery stores, supermarkets, hypermarkets, wholesalers, bulk food stores, produce outlets, butchers, delis, fish and seafood shops, juice/smoothie bars, and fresh and healthy quick-service retailers; and ‘less healthy’ food retailers included fast-food restaurants, convenience stores, coffee shops, dollar stores, pharmacies, bubble tea restaurants, candy stores, frozen dessert restaurants, bakeries, and food trucks. Based on 2021 government food premise licences, we used geographic information systems software to evaluate spatial accessibility of healthy and less healthy food retailers across census tracts and in proximity to schools, calculating differences between the traditional v. expanded mRFEI.

Calgary and Edmonton, Canada.

N/A.

Of the 10 828 food retailers geocoded, 26 % were included using traditional mRFEI measures, while 53 % were included using our expanded categorisation. Changes in mean mRFEI across census tracts were minimal, but the healthfulness of food environments surrounding schools significantly decreased.

Overall, we show how our mRFEI adaptation, and transparent reporting on its use, can promote more nuanced and comprehensive food environment assessments to better support local research, policy and practice innovations.
