Developing a clinical decision support system software prototype that assists in the management of patients with self-harm in the emergency department: protocol of the PERMANENS project

BACKGROUND

Self-harm presents a significant public health challenge. Emergency departments (EDs) are crucial healthcare settings in managing self-harm, but clinician uncertainty in risk assessment may contribute to ineffective care. Clinical Decision Support Systems (CDSSs) show promise in enhancing care processes, but their effective implementation in self-harm management remains unexplored.

METHODS

PERMANENS comprises a combination of methodologies and study designs aimed at developing a CDSS prototype that assists clinicians in the personalized assessment and management of ED patients presenting with self-harm. Ensemble prediction models will be constructed by applying machine learning techniques on electronic registry data from four sites, i.e., Catalonia (Spain), Ireland, Norway, and Sweden. These models will predict key adverse outcomes including self-harm repetition, suicide, premature death, and lack of post-discharge care. Available registry data include routinely collected electronic health record data, mortality data, and administrative data, and will be harmonized using the OMOP Common Data Model, ensuring consistency in terminologies, vocabularies and coding schemes. A clinical knowledge base of effective suicide prevention interventions will be developed rooted in a systematic review of clinical practice guidelines, including quality assessment of guidelines using the AGREE II tool. The CDSS software prototype will include a backend that integrates the prediction models and the clinical knowledge base to enable accurate patient risk stratification and subsequent intervention allocation. The CDSS frontend will enable personalized risk assessment and will provide tailored treatment plans, following a tiered evidence-based approach. Implementation research will ensure the CDSS' practical functionality and feasibility, and will include periodic meetings with user-advisory groups, mixed-methods research to identify currently unmet needs in self-harm risk assessment, and small-scale usability testing of the CDSS prototype software.

DISCUSSION

Through the development of the proposed CDSS software prototype, PERMANENS aims to standardize care, enhance clinician confidence, improve patient satisfaction, and increase treatment compliance. The routine integration of CDSS for self-harm risk assessment within healthcare systems holds significant potential in effectively reducing suicide mortality rates by facilitating personalized and timely delivery of effective interventions on a large scale for individuals at risk of suicide.

Two Sides of the Coin: The Roles of Adverse Childhood Experiences and Positive Childhood Experiences in College Students' Mental Health

Several studies have established a link between adverse childhood experiences (ACEs) and mental health issues in college students. However, less is known about how positive childhood experiences (PCEs) may promote mental health and well-being, and potentially act as a buffer in the relationship between risk exposure and poor outcomes. This study investigates how ACEs and PCEs relate to college students' mental health (N = 321), within the framework of Resiliency Theory with specific attention focus on the compensatory and the protective factors models. Three key hypotheses were examined using quantitative data collected by way of an online anonymous survey: (1) ACEs will predict poorer mental health outcomes; (2) PCEs will predict better mental health outcomes and will lessen the negative effects of ACEs on mental health outcomes (compensatory factor model), and (3) PCEs will moderate the association between ACEs and mental health outcomes so that the relationship will be weaker among participants with higher PCEs (protective factor model). Findings supported each of these hypotheses and are important for our understanding of the long-term mental health correlates of ACEs and PCEs among college students. Our study underscores the importance of promoting PCEs while also underscoring the necessity of proactively preventing ACEs. Practical implications are discussed in relation to improving assessments of student needs and providing targeted interventions for those at risk.

Risk factors for COVID-19-related stress among college-going students

OBJECTIVE

To explore the degree of COVID-19-related stress among college students enrolled in higher level institutions and identify socio-demographic and psychosocial factors that may predict, or be associated with, higher levels of pandemic-related distress.

METHOD

Data were obtained from a cross-sectional survey completed by 321 college students primarily recruited from Universities in Ireland. Ages ranged between 18-21 years (n = 176) and 22-25 years (n = 145). Participants answered some demographic questions before completing scales assessing their experience of childhood adversity, their present resilience and levels of psychological distress, as well as their COVID-19-specific stress.

RESULTS

Multiple regression analysis revealed that students who were female, who had chronic illness, who experienced monetary concerns and who expressed psychological distress experienced greater stress related to COVID-19.

CONCLUSION

Findings suggest that certain categories of college students may be at higher risk for experiencing poor mental health during a global pandemic. Higher level institutions should consider this when designing and delivering support services aiming to promote student mental health and alleviate mental distress.

Role of thwarted belongingness, perceived burdensomeness and psychological distress in the association between adverse childhood experiences and suicidal ideation in college students

BACKGROUND

Adverse childhood experiences (ACEs) have a detrimental impact on short- and long-term mental and physical health. A growing body of research has indicated that the prevalence of suicidal phenomena is significantly higher among individuals with a history of ACEs. However, there is a lack of understanding about processes that result in ACEs leading to suicidal ideation when testing within a theoretical framework.

AIMS

To develop and test a multidimensional model that would explain the association between ACEs and suicidal ideation in college students.

METHOD

Data were obtained from a cross-sectional survey completed by 321 college students primarily recruited from universities in Ireland. Participants were aged 18-21 (n = 176) and 22-25 years (n = 145). An ACEs questionnaire, the Interpersonal Needs Questionnaire, which assessed thwarted belongingness and perceived burdensomeness, the CORE-10, which assessed psychological distress, and the Suicide Ideation Scale (SIS) were administered.

RESULTS

After controlling for gender and sexual orientation, results revealed a significant direct effect of ACEs on suicidal ideation such that more accumulated ACEs were associated with higher suicidal ideation (effect size 0.30; 95% CI 0.047-0.538). A significant indirect effect of ACEs on suicidal ideation through perceived burdensomeness and psychological distress, and thwarted belongingness and psychological distress, was observed (effect size 0.90; 95% CI 0.558-1.270).

CONCLUSIONS

Findings suggest that ACEs have a detrimental impact on college students' mental health. Results highlight the potential benefits of ACE-informed interventions that target thwarted belongingness and perceived burdensomeness to countervail suicidal ideation in college students.

Comparative Assessment of Revascularization Versus Drug Management in Coronary Artery Disease (CAD) Associated with Left Ventricular Dysfunction (EF < 40%) - A 12 Month Study with FDG PET and SPECT MPI Analyses

AIM OF THE STUDY

Left Ventricular (LV) function and myocardial viability is the key predictor of prognosis after myocardial infarction. Management of ischemic cardiomyopathy (revascularization and or drugs alone) is the objective of this study.

METHODOLOGY

72 patients were assigned to revascularization and medical management group based on the inclusion criteria Follow up was done upto 12 months with advanced imaging techniques (FDG PET and SPECT MPI analyses).

RESULTS

Subjects with significant viable myocardium, revascularization resulted in significant improvement in heart failure symptoms. The mean NYHA functional class improved from 2.9 ± 0.3 to 2.3 ± 0.5(mean ± SD) after 6 months of revascularization (p < 0.01). This improvement in functional class was maintained after 12 months of revascularization (2.0 ± 0.4 (mean ± SD). Subjects on medical management with a baseline NYHA functional class 2.7 ± 0.5, at 6 months of follow, there was no significant change in functional class (2.8 ± 0.3) (p<0.24). However at 12 months follow up functional class had dropped to 3.0 + 0.3, which was significant as compared to baseline (p <0.03).

CONCLUSION

coronary revascularization has a protective effect on patients with ischemic coronary who have viable myocardium and reversible myocardial ischemia as assessed by 18F-FDG PET and SPECT MPI Imaging.

Aggressive natural killer cell leukaemia: a rare and fatal disorder

Natural killer (NK) cell neoplasms, which include extra-nodal NK/T-cell lymphoma (nasal and extra-nasal) and aggressive NK cell leukaemia, are generally rare, but they are more common in people of Oriental, Mexican and South American descent. These neoplasms are highly aggressive, and show a strong association with Epstein-Barr virus. Aggressive NK cell leukaemia affects younger patients, who present with poor general condition, fever, and disseminated disease; they often die within a short time from systemic disease or complications such as multi-organ failure. Aggressive NK cell leukaemia must be distinguished from T-cell large granular lymphocyte leukaemia and indolent NK cell lympho-proliferative disorder, both of which are indolent. We present a case of young Asian male with aggressive NK cell leukaemia who presented with a poor general condition and disseminated disease. The patient had a rapidly progressive disease and died within weeks of diagnosis.
