Racially and ethnically minoritized individuals, first-generation college students, and women are significantly underrepresented in science, technology, engineering, and mathematics (STEM) careers. This lack of equal representation limits creativity and progress in these fields and perpetuates systemic barriers that discourage students from pursuing STEM pathways. This special communication introduces the three-tiered mentorship model employed in the Teen Science Ambassador Program (TSAP), which incorporates senior mentors, near-peer mentors, and high school ambassadors (i.e., mentees) to promote education, hands-on research, and career development in STEM for underrepresented students. We discuss the benefits and challenges of the three-tiered model and offer recommendations for optimizing its effectiveness to enhance mentorship experiences for all participants. Findings from the TSAP program suggest that the three-tiered approach benefited all participants: high school ambassadors gained STEM skills and confidence, near-peer mentors developed leadership and communication abilities, and senior mentors improved mentorship skills. However, the effectiveness of near-peer mentorship is highly dependent on clearly defined roles and structured involvement. Thus, feedback collected from each mentorship tier was used to inform subsequent iterations of the program. The layered mentorship structure fostered a sense of community and belonging, which is crucial for retaining individuals from underrepresented groups in STEM.
Task-sharing approaches that train non-specialist providers (NSPs), people without specialized clinical training, are increasingly utilized to address the global mental health treatment gap. This review consolidates findings from peer reviewed articles on the impact of task-sharing mental health interventions on NSPs at the individual, family and community level. Studies that highlighted facilitators, barriers and recommendations for improving the experiences of NSPs were also included in the review. Fifteen studies, conducted across eight countries, met the inclusion criteria. Seven studies were conducted in Sub-Saharan Africa, six in South and Southeast Asia and two studies were conducted in high-income countries in Europe. Benefits for NSPs included personal application of mental health skills, elevated community status and increased social networks. Challenges include burnout, lack of career progression and difficult workplace environments. Findings indicate that while there were many positive impacts associated with NSPs’ work, challenges need to be addressed. Safety and harassment issues reported by female NSPs are especially urgent. Supervision, certifications, increased salaries and job stability were also recognized as significant opportunities. We recommend future intervention studies to collect data on the impact of intervention delivery on NSPs. Research is also needed on the impact of various supervision and health systems strategies on NSPs.
Adolescence is a critical developmental phase during which young people are vulnerable to the experiences of mental ill-health and social exclusion (consisting of various domains including education and employment, housing, finances and social supports and relationships). The aims of this study were to (i) obtain an understanding of the relationships between social exclusion, mental health and wellbeing of young people; and (ii) identify potentially modifiable targets, or population groups that require greater or targeted supports.
Methods
Data were obtained from the Mission Australia 2022 Youth Survey, Australia’s largest annual population-wide survey of young people aged 15–19 years (n = 18,800). Participants’ experiences of social exclusion in different domains were explored (e.g., prevalence, co-occurrence and controlling for differences in demographic characteristics). Multivariable linear regression models were used to map the relationships between social exclusion domains and mental health and wellbeing, controlling for confounding factors where necessary.
Results
Sixty per cent of all young people experienced social exclusion in at least one domain, 25% in multiple. Young people who identified as gender diverse, Indigenous, living in a remote/rural or socio-economically disadvantaged area and with a culturally diverse background were more likely to report social exclusion. A strong association was seen between all domains of social exclusion and poor mental health (e.g., higher psychological distress and loneliness, reduced personal wellbeing, reduced sense of control over their life and a more negative outlook on the future). Notably, difficulties in socialising and obtaining social support were critical factors linked to increased psychological distress and reduced wellbeing.
Conclusions
Findings underscore the need to address multiple domains of social exclusion concurrently, and in collaboration with youth mental healthcare. Prevention efforts aimed at early identification and intervention should be prioritised to support young people vulnerable to social exclusion. Screening approaches are needed to identify individuals and groups of young people in need of support, and to facilitate care coordination across multiple providers.
Exploratory process factor analysis (EPFA) is a data-driven latent variable model for multivariate time series. This article presents analytic standard errors for EPFA. Unlike standard errors for exploratory factor analysis with independent data, the analytic standard errors for EPFA take into account the time dependency in time series data. In addition, factor rotation is treated as the imposition of equality constraints on model parameters. Properties of the analytic standard errors are demonstrated using empirical and simulated data.
The majority of studies of mental health interventions for young adolescents have only evaluated short-term benefits. This study evaluated the longer-term effectiveness of a non-specialist delivered group-based intervention (Early Adolescent Skills for Emotions; EASE) to improve young adolescents’ mental health.
Methods
In this single-blind, parallel, controlled trial, Syrian refugees aged 10-14 years in Jordan who screened positive for psychological distress were randomised to receive either EASE or enhanced usual care (EUC). Primary outcomes were scores on the Paediatric Symptom Checklist (PSC) assessed at Week 0, 8-weeks, 3-months, and 12 months after treatment. Secondary outcomes were disability, posttraumatic stress, school belongingness, wellbeing, and caregivers’ reports of distress, parenting behaviour, and their perceived children’s mental health.
Results
Between June, 2019 and January, 2020, 185 adolescents were assigned to EASE and 286 to EUC, and 149 (80.5%) and 225 (78.7%) were retained at 12 months, respectively. At 12 months there were no significant differences between treatment conditions, except that EASE was associated with less reduction in depression (estimated mean difference -1.6, 95% CI –3.2 to -0.1; p=.03; effect size, -0.3), and a greater sense of school belonging (estimated mean difference -0.3, 95% CI –5.7 to -0.2; p=.03; effect size, 5.0).
Conclusions
Although EASE led to significant reductions in internalising problems, caregiver distress, and harsh disciplinary parenting at 3-months, these improvements were not maintained at 12 months relative to EUC. Scalable psychological interventions for young adolescents need to consider their ongoing mental health needs. Prospectively registered: ACTRN12619000341123.
The performance and confidence in fault detection and diagnostic systems can be undermined by data pipelines that feature multiple compounding sources of uncertainty. These issues further inhibit the deployment of data-based analytics in industry, where variable data quality and lack of confidence in model outputs are already barriers to their adoption. The methodology proposed in this paper supports trustworthy data pipeline design and leverages knowledge gained from one fully-observed data pipeline to a similar, under-observed case. The transfer of uncertainties provides insight into uncertainty drivers without repeating the computational or cost overhead of fully redesigning the pipeline. A SHAP-based human-readable explainable AI (XAI) framework was used to rank and explain the impact of each choice in a data pipeline, allowing the decoupling of positive and negative performance drivers to facilitate the successful selection of highly-performing pipelines. This empirical approach is demonstrated in bearing fault classification case studies using well-understood open-source data.
Monitoring cerebral and renal near-infrared spectroscopy for regional venous oxygenation is a common practice in the postoperative care of neonates recovering from surgery for CHD. In this study, we aimed to test the feasibility of using this technology for monitoring changes in splanchnic perfusion during feeds in infants recovering from cardiac surgery.
Methods:
We monitored renal and splanchnic near-infrared spectroscopy in 29 neonates once recovered from the critical postoperative state and tolerating full enteral nutrition. Infants were tested over 3 feeds for splanchnic regional oxygenation (rO2), arterial to splanchnic saturation difference and splanchnic to renal regional oxygenation ratio.
Result:
Splanchnic regional oxygenation data were obtained with no failure or interruptions. Interclass correlation for agreement between measurements suggested good repeatability: 0.84 at baseline and 0.82 at end of feed. Infants with physiologic repair (n = 19) showed a trend towards increased splanchnic regional oxygenation at the end of feeds and were more likely to achieve regional oxygenation > 50% compared to infants with shunt-dependent circulation (n = 10, p = 0.02). Calculating AVO2 and regional oxygenation index did not result in improved test sensitivity.
Conclusion:
Monitoring splanchnic regional oxygenation during feeds for infants recovering from congenital heart surgery is feasible and reliable. These results suggest that near-infrared spectroscopy could be further studied as a tool for bedside monitoring to assist in feeding management and prevention of necrotising enterocolitis in this sensitive patient population.
Post-procedural antimicrobial prophylaxis is not recommended by professional guidelines but is commonly prescribed. We sought to reduce use of post-procedural antimicrobials after common endoscopic urologic procedures.
Design:
A before-after, quasi-experimental trial with a baseline (July 2020–June 2022), an implementation (July 2022), and an intervention period (August 2022–July 2023).
Setting:
Three participating medical centers.
Intervention:
We assessed the effect of a bundled intervention on excess post-procedural antimicrobial use (ie, antimicrobial use on post-procedural day 1) after three types of endoscopic urologic procedures: ureteroscopy and transurethral resection of bladder tumor or prostate. The intervention consisted of education, local champion(s), and audit-and-feedback of data on the frequency of post-procedural antimicrobial-prescribing.
Results:
1,272 procedures were performed across all 3 sites at baseline compared to 525 during the intervention period; 644 (50.6%) patients received excess post-procedural antimicrobials during the baseline period compared to 216 (41.1%) during the intervention period. There was no change in the use of post-procedural antimicrobials at sites 1 and 2 between the baseline and intervention periods. At site 3, the odds of prescribing a post-procedural antimicrobial significantly decreased during the intervention period relative to the baseline time trend (0.09; 95% CI 0.02–0.45). There was no significant increase in post-procedural unplanned visits at any of the sites.
Conclusions:
Implementation of a bundled intervention was associated with reduced post-procedural antimicrobial use at one of three sites, with no increase in complications. These findings demonstrate both the safety and challenge of guideline implementation for optimal perioperative antimicrobial prophylaxis.
This trial was registered on clinicaltrials.gov, NCT04196777.
Interpersonal psychotherapy (IPT) and antidepressant medications are both first-line interventions for adult depression, but their relative efficacy in the long term and on outcome measures other than depressive symptomatology is unknown. Individual participant data (IPD) meta-analyses can provide more precise effect estimates than conventional meta-analyses. This IPD meta-analysis compared the efficacy of IPT and antidepressants on various outcomes at post-treatment and follow-up (PROSPERO: CRD42020219891). A systematic literature search conducted May 1st, 2023 identified randomized trials comparing IPT and antidepressants in acute-phase treatment of adults with depression. Anonymized IPD were requested and analyzed using mixed-effects models. The prespecified primary outcome was post-treatment depression symptom severity. Secondary outcomes were all post-treatment and follow-up measures assessed in at least two studies. IPD were obtained from 9 of 15 studies identified (N = 1536/1948, 78.9%). No significant comparative treatment effects were found on post-treatment measures of depression (d = 0.088, p = 0.103, N = 1530) and social functioning (d = 0.026, p = 0.624, N = 1213). In smaller samples, antidepressants performed slightly better than IPT on post-treatment measures of general psychopathology (d = 0.276, p = 0.023, N = 307) and dysfunctional attitudes (d = 0.249, p = 0.029, N = 231), but not on any other secondary outcomes, nor at follow-up. This IPD meta-analysis is the first to examine the acute and longer-term efficacy of IPT v. antidepressants on a broad range of outcomes. Depression treatment trials should routinely include multiple outcome measures and follow-up assessments.
Despite the global expansion of electronic medical record (EMR) systems and their increased integration with artificial intelligence (AI), their utilization in disaster settings remains limited, and few studies have evaluated their implementation. We aimed to evaluate Fast Electronic Medical Record (fEMR), a novel, mobile EMR designed for resource-limited settings, based on user feedback.
Methods
We examined usage data through October 2022 to categorize the nature of its use for disaster response and determine the number of patients served. We conducted interviews with stakeholders and gathered input from clinicians who had experience using fEMR.
Results
Over eight years, fEMR was employed 60 times in 11 countries across four continents by 14 organizations (universities, non-profits, and disaster response teams). This involved 37,500+ patient encounters in diverse settings including migrant camps at the US-Mexico and Poland-Ukraine borders, mobile health clinics in Kenya and Guatemala, and post-earthquake relief in Haiti. User feedback highlighted adaptability, but suggested hardware and workflow improvements.
Conclusion
EMR systems have the potential to enhance healthcare delivery in humanitarian responses, offer valuable data for planning and preparedness, and support measurement of effectiveness. As a simple, versatile EMR system, fEMR has been deployed to numerous disaster response and low-income settings.
Assess healthcare workers’ (HCW) attitudes toward universal masking, and gowns and gloves used as part of transmission-based precautions.
Design:
Cross-sectional survey.
Setting:
Academic, tertiary care medical center in Baltimore, Maryland.
Participants:
HCW who work in patient care areas and have contact with patients.
Methods:
In May 2023, a 15-question web-based survey was distributed by the hospital’s communications team via email. The survey contained questions to assess HCW perceptions of universal masking policies prior to the availability of COVID-19 vaccines and at the time of the survey, and the use of gowns and gloves for transmission-based precautions. Descriptive statistics were used to summarize data. Differences in agreement with universal masking over time, level of agreement with gown and glove policies, and with all PPE types across respondent characteristics were assessed.
Results:
257 eligible respondents completed the survey. Nurses and patient care technicians (43%) and providers (17%) were the most commonly reported roles. Agreement with universal mask use decreased from 84% early in the pandemic to 55% at the time of the survey. 70% and 72% of HCW agreed masks protect themselves and others, respectively. 63% expressed any level of annoyance with mask wearing, the most often due to communication challenges or physical discomfort. 75% agreed with gown use for antibiotic-resistant bacteria compared with 90% for glove use.
Conclusions:
The majority of HCW agree with the use of PPE to prevent pathogen transmission in the healthcare setting. Agreement with universal mask use for patient care shifted during the COVID-19 pandemic.
Accelerating COVID-19 Treatment Interventions and Vaccines (ACTIV) was initiated by the US government to rapidly develop and test vaccines and therapeutics against COVID-19 in 2020. The ACTIV Therapeutics-Clinical Working Group selected ACTIV trial teams and clinical networks to expeditiously develop and launch master protocols based on therapeutic targets and patient populations. The suite of clinical trials was designed to collectively inform therapeutic care for COVID-19 outpatient, inpatient, and intensive care populations globally. In this report, we highlight challenges, strategies, and solutions around clinical protocol development and regulatory approval to document our experience and propose plans for future similar healthcare emergencies.
People with severe mental illness (SMI), including schizophrenia and bipolar disorder, experience significant health inequalities and are more likely to develop long-term physical health conditions (LTCs), such as type 2 diabetes and cardiovascular disease. Many people with SMI rely on informal caregivers, typically friends and family, to support their health and enable them to live in the community. Informal caregivers of people with SMI experience high levels of caregiver burden, social isolation, and poor health outcomes. However, it is unclear how co-existing LTCs contribute to the caregiving experience.
Objectives
The aim of this study was to explore the lived experience of informal caregivers of people with co-existing SMI and LTCs.
Methods
We conducted a qualitative study with informal caregivers of people with co-existing SMI and LTCs in England. We recruited 12 informal caregivers and conducted five semi-structured interviews and two focus groups between December 2018 and April 2019. The interviews and focus groups were audio recorded, transcribed verbatim and thematically analysed.
Results
SMI impacts profoundly on the health and well-being of both service users and their informal caregivers. Service users were described as too unwell with their SMI to engage in self-management of their mental and physical health, with the primary responsibility for these tasks falling to informal caregivers. There were significant barriers to adequate physical healthcare for service users, therefore informal caregivers needed to advocate extensively for their loved ones to ensure access to services. Informal caregivers felt significantly under-supported and struggled with the caregiver burden associated with SMI and LTCs. This burden included the constant monitoring of risk, anxiety around the vulnerability of their loved one, repeated hospitalisations, physical health concerns, lack of respite services, lack of recognition of their role, the guilt associated with paternalistic care, shame and stigma, and the difficulties managing the changeable nature of SMI.
Conclusions
Informal caregivers of people with SMI face an additional caregiver burden resulting from co-existing LTCS. This adds substantially to their caring role, yet they do not receive the necessary support, and therefore their own health and wellbeing are negatively impacted. Improved recognition of the role of informal caregivers and additional support, including improved provision of respite services, are needed to improve the well-being of informal caregivers.

Biotite was altered by boiling in 0.2 M A1C13 solution, and the products were examined by X-ray powder and single-crystal diffraction, chemical analysis and thermogravimetry. The altered material is a 14 Å clay mineral with hydroxy-Al interlayers. It has a stacking sequence characteristic of vermiculite and its silicate layers are similar in chemical composition to trioctahedral vermiculite. The results of extracting the interlayer material with sodium citrate solution, X-ray examinations after heating and thermogravimetry show that the interlayer material is composed of Al associated with OH and H2O. The chemistry and kinetics of the alteration reaction and the orientational between the altered and original biotites are also discussed.
This investigation was designed to integrate the quick-freeze technique for ion diffusion with two computer programs to permit the simultaneous measurement and calculation of the diffus-ivity of a variable number of ions in heteroionic soil system. Kaolinite clay was prepared so as to have the following percentage saturations of the CEC, Sr2+65, Mg2+15, Rb+10, Na+5 and H+5. A quadruplicate radioisotope tag consisting of 85Sr, 28Mg, 86Rb, and 22Na was used to measure the diffusivity of each ion. The complex spectra were resolved by use of Schonfeld’s revised Alpha-M computer program. A probit-transformation procedure was formulated into a computer program to enable the calculation of each diffusion coefficient. These programs are described and illustrated with the diffusivity of 86Rb in kaolinite clay.
The effect of varying concentrations of Al3+ and H+ upon the simultaneous diffusion of 85Sr and 86Rb was measured in salt-free aliquots of clay having different Al:H ratios. The Sr and Rb saturation of the CEC was held constant while the exchangeable Al and H were varied from Al52:H1 to Al12:H34. Aliquots of each clay-treatment were dually tagged with 85Sr and 86Rb. Self-diffusion of Sr and Rb was measured at 4, 24, 48, and 75°C. Radioassay of 85Sr and 86Rb was made with an automatic gamma-detection system equipped with a 400 channel analyzer and card punch unit. The selfdiffusion equation was programmed for the 7040 computer to permit the simultaneous calculation of 85Sr and 86Rb self-diffusion coefficients. Rb diffusion was not significantly altered as the Al3+ concentration was increased from 12 to 52 per cent. The diffusion of Sr was significantly increased as Al3+ increased from 12 to 52 per cent. The faster diffusing Rb ion had a greater energy of activation than Sr (4·8 to 3·6 kcal/mole), however the Arrhenius frequency factor for Rb (a measure of the probability of ion exchange) was much greater for Rb than Sr (28·8 and 0·4 × 10−4, respectively). Altering the Rb and Sr saturation and the complementary ions resulted in changes in the diffusivity, the energy of activation, and the frequency factor for these ions, but not always in the same direction or to the same degree.
An electrooptic birefringence technique was employed to study the effect of particle size, saturating cation, and clay type on the rotational diffusion coefficient (a measure of the rate at which the particles rotate or relax within the solution) from a preferred orientation. These studies help elucidate the nature of the cation—water environment near the clay particles.
Previous work has shown that some clay particles orient at both low and high voltages due to a permanent dipole and an induced dipole, respectively, whereas other clays under similar short-duration pulses orient only at high voltages. The permanent dipole was attributed to the iron in the octahedral layer of the clay mineral, whereas the induced dipole was probably due to a redistribution of the diffuse double-layer cations. This study shows that smaller clay particles orient more readily at low voltages and have greater rotational diffusion coefficients at high voltages. The higher the rotational diffusion coefficient, the faster the particles move in their surrounding water-cation environment. The effect of the saturating cation on the rotational diffusion coefficients was Na > Li > K for the permanent dipole and K > Li > Na > Ca > Mg for the induced dipole orientation. Previous results (Schepers and Miller, 1974) are interpreted to mean that a particle in dilute suspension can rotate independently of its environment only when the salt concentration in the surrounding medium approaches zero. At higher salt concentrations, or if the particle environment is perturbed by an electric field, the particle rotates with a water shell. As the concentration of salt or strength of the electric field increases further, either the viscosity of the surrounding solution increases or the size of the rotating shell is greatly increased. Thus, the water around clay particles appears to be structurally different than normal, and this condition is probably caused by the nature of the clay—cation interaction.
Suicide is a leading cause of death in the United States, particularly among adolescents. In recent years, suicidal ideation, attempts, and fatalities have increased. Systems maps can effectively represent complex issues such as suicide, thus providing decision-support tools for policymakers to identify and evaluate interventions. While network science has served to examine systems maps in fields such as obesity, there is limited research at the intersection of suicidology and network science. In this paper, we apply network science to a large causal map of adverse childhood experiences (ACEs) and suicide to address this gap. The National Center for Injury Prevention and Control (NCIPC) within the Centers for Disease Control and Prevention recently created a causal map that encapsulates ACEs and adolescent suicide in 361 concept nodes and 946 directed relationships. In this study, we examine this map and three similar models through three related questions: (Q1) how do existing network-based models of suicide differ in terms of node- and network-level characteristics? (Q2) Using the NCIPC model as a unifying framework, how do current suicide intervention strategies align with prevailing theories of suicide? (Q3) How can the use of network science on the NCIPC model guide suicide interventions?
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.
Methods:
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.
Results:
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).
Conclusion:
Our study underscores the importance of assessing individual-level SDoH variables to unravel the complex interplay of these factors for racialized minority groups.
The escalating threat of antimicrobial resistance (AMR) necessitates impactful, reproducible, and scalable antimicrobial stewardship strategies. This review addresses the critical need to enhance the quality of antimicrobial stewardship intervention research. We propose five considerations for authors planning and evaluating antimicrobial stewardship initiatives. Antimicrobial stewards should consider the following mnemonic ABCDE: (A) plan Ahead using implementation science; (B) Be clear and thoroughly describe the intervention by using the TidIER checklist; (C) Use a Checklist to comprehensively report study components; (D) Select a study Design carefully; and (E) Assess Effectiveness and implementation by selecting meaningful outcomes. Incorporating these recommendations will help strengthen the evidence base of antimicrobial stewardship literature and support optimal implementation of strategies to mitigate AMR.
