Developing an instrument to measure nursing students’ attitudes towards nurses during clinical practice: A quantitative study

AimThis study was conducted to develop a valid and reliable measurement tool to determine nursing students’ attitudes towards nurses during the clinical practice. BackgroundNurses affect the clinical practice process of nursing students and play an important role in the latter gaining experience. Evaluation of students’ attitudes towards nurses is a critical factor for the training of qualified nurses. DesignThis study used a quantitative cross-sectional design. MethodsThis study was conducted between February and March 2024 with 408 students studying in the nursing department of a university in Türkiye. The item pool of the scale was formed with 45 items through literature review and qualitative data analysis and presented to 21 experts. After the content validity, the draft scale consisting of 38 items was used as a data collection tool. Lawshe’s Content Validity Ratio, Kaiser-Mayer-Olkin Coefficient, Bartlett’s test, Exploratory Factor Analysis, Principal Component Analysis, Varimax Factor Rotation Method, Confirmatory Factor Analysis, Cronbach’s Alpha Internal Consistency Coefficient, Spearman Correlation Coefficient and Wilcoxon Signed Ranks tests were used to analyze the data. ResultsExploratory factor analysis revealed 28 items and three sub-dimensions in the scale. Cronbach’s alpha internal consistency coefficient was 0.902 for the cooperation and understanding sub-dimension, 0.925 for the communication skills and guidance sub-dimension, 0.723 for the support for professional development sub-dimension and 0.946 for the total scale. According to the confirmatory factor analysis fit index results of the scale, RMSEA value was 0.054 and χ2/df value was 2.189. As a result of the analysis conducted to determine the test-retest reliability, it was determined that all items and factor scores showed significant relationships between the two applications (p<0.001). ConclusionsThe scale was found to be a valid and reliable measurement tool that can be used to determine nursing students’ attitudes towards nurses during the clinical practice.

Efficacy of KarXT on negative symptoms in acute schizophrenia: A post hoc analysis of pooled data from 3 trials

BackgroundCurrently approved antipsychotics do not adequately treat negative symptoms (NS), which are a major determinant of functional disability in schizophrenia. KarXT, an M1 /M4 preferring muscarinic receptor agonist, has shown efficacy as a broad-spectrum monotherapy for the treatment of schizophrenia in participants with acute psychosis. Post hoc analyses evaluated the possibility that NS improve independently of positive symptoms with KarXT in a subgroup of participants with moderate-to-severe NS and no predominance of positive symptoms. MethodsData were pooled from the three pivotal trials of KarXT monotherapy in people with schizophrenia with an acute exacerbation of psychosis. All 3 studies used similar 5-week randomized, double-blind, placebo-controlled designs (modified intention-to-treat sample N = 640). PANSS criteria proposed in the literature identified a subset of study participants (n = 64) with prominent NS. ResultsKarXT was significantly better than placebo on PANSS Marder Negative Factor Scores in the full sample (p < .001; Cohen's d = 0.42) and more so in the prominent NS subgroup (p < .001; Cohen's d = 1.18). Further, the KarXT effect in the NS subgroup remained significant after accounting for changes in positive symptoms, depression/anxiety, disorganization, and hostility. ConclusionsParticipants with prominent NS revealed greater improvement of NS following KarXT therapy than the full sample that persisted after accounting for positive and other symptoms. While these findings must be interpreted with caution, they are consistent with the possibility that NS improvements associated with KarXT are not secondary to improvements in other symptom domains and support further investigation in larger, stable outpatient studies.

Factors influencing the organizational engagement of village health volunteers, after the COVID-19 Outbreak in Phayao Province

Village health volunteers (VHVs) play a crucial role in promoting health advancements and enhancing community well-being. This cross-sectional descriptive study explores the factors that influence organizational engagement among VHVs in Phayao Province. Data were gathered from 400 volunteers using Krejcie and Morgan’s formula and analyzed through a questionnaire. Analytical methods included descriptive statistics, Pearson’s product-moment correlation, and multiple linear regression. The findings revealed that the majority of volunteers were female (77%), aged between 41-60 years (62.3%), married (81.3%), with over ten years of experience (61%), and had educational levels of high school or vocational certificate (46.8%). Most were agriculturists (63.5%), with incomes below 5,000 baht (54%), and served as general members (74.5%) in a single role (78.8%), primarily under the provincial administrative organization (54%). The scores for motivational factors, quality of life, and organizational engagement were high. Responsibility, the nature of work, and respect were identified as significant predictors of organizational engagement, accounting for 51.1% of the variance. These findings were statistically significant (R = 0.715, R Square = 0.511, P-value &lt; 0.001). Based on these results, organizations are encouraged to ensure appropriate working conditions and respect to enhance engagement among village health volunteers.

Social relationship factors, depressive symptoms, and incident dementia: a prospective cohort study into their interrelatedness.

Different aspects of social relationships (e.g., social network size or loneliness) have been associated with dementia risk, while their overlap and potentially underlying pathways remain largely unexplored. This study therefore aimed to (1) discriminate between different facets of social relationships by means of factor analysis, (2) examine their associations with dementia risk, and (3) assess mediation by depressive symptoms. Thirty-six items from questionnaires on social relationships administered in Wave 2 (2004/2005) of the English Longitudinal Study of Ageing (n = 7536) were used for exploratory and confirmatory factor analysis. Factors were then used as predictors in Cox proportional hazard models with dementia until Wave 9 as outcome, adjusted for demographics and cardiovascular risk factors. Structural equation modeling tested mediation by depressive symptoms through effect decomposition. Factor analyses identified six social factors. Across a median follow-up time of 11.8 years (IQR = 5.9-13.9 years), 501 people developed dementia. Higher factor scores for frequency and quality of contact with children (HR = 0.88; p = 0.021) and more frequent social activity engagement (HR = 0.84; p < 0.001) were associated with lower dementia risk. Likewise, higher factor scores for loneliness (HR = 1.13; p = 0.011) and negative experiences of social support (HR = 1.10; p = 0.047) were associated with higher dementia risk. Mediation analyses showed a significant partial effect mediation by depressive symptoms for all four factors. Additional analyses provided little evidence for reverse causation. Frequency and quality of social contacts, social activity engagement, and feelings of loneliness are associated with dementia risk and might be suitable targets for dementia prevention programs, partly by lowering depressive symptoms.

The potential predictive value and relationship of blood-based inflammatory markers with the clinical symptoms of Han Chinese patients with first-episode adolescent-onset schizophrenia.

Inflammation is associated with the pathophysiology of schizophrenia. The blood markers for systemic inflammation include neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), lymphocyte-monocyte ratio (LMR), system inflammation response index (SIRI), and platelet-lymphocyte ratio (PLR). However, these inflammation markers and their relationships with clinical phenotypes among Han Chinese patients with first-episode adolescent-onset schizophrenia (AOS) is unclear. This investigation aimed to elucidate the impact of inflammation on Han Chinese AOS patients as well as the association of blood-based inflammation markers with clinical symptoms. Altogether, 203 Han Chinese individuals participated in this study, 102 first-episode AOS patients and 101 healthy controls. The assessment of inflammatory indices was based on complete blood cell count. Furthermore, schizophrenia-related clinical symptoms were evaluated using the five-factor model of the Positive and Negative Syndrome Scale (PANSS). In Han Chinese first-episode AOS patients, levels of SIRI, PLR, SII, and NLR were significantly increased (p < 0.001), while LMR decreased (p < 0.001) compared to healthy controls. Furthermore, multivariate logistic regression showed that LMR, NLR, SII, and SIRI (all p < 0.05) were independently associated with AOS. Moreover, Receiver operating characteristics assessment indicated that NLR, SIRI, LMR, and SII could effectively distinguish AOS patients from healthy controls. Their areas under the curves were 0.734, 0.701, 0.715, and 0.730 (all p < 0.001). In addition, Correlation analysis revealed that LMR was negatively correlated with the PANSS total, negative, and cognitive factor scores (all p < 0.05); NLR was positively correlated with the cognitive factor score (p < 0.01); SII was negatively correlated with the positive factor score and positively with the negative and cognitive factor scores (all p < 0.05); SIRI was positively correlated with the PANSS total and cognitive factor scores (all p < 0.01). This research established the involvement of peripheral blood inflammatory markers (LMR, NLR, SII, and SIRI) with the clinical manifestations and pathophysiology of schizophrenia, and these can serve as screening tools or potential indices of the inflammatory state and AOS symptoms severity.

Treatment of Neuropsychiatric Symptoms in Parkinson's Disease With Botulinum Toxin A: A 12 week Randomized, Double-Blind, Placebo-Controlled Trial.

The study aimed to evaluate the impact of Botulinum toxin A (BoNT/A) on neuropsychiatric symptoms in Parkinson's disease (PD) patients. A total of 125 PD patients and an equal number of age- and gender-matched healthy controls were involved. Mental health status was assessed using the Cornell Medical Index (CMI) self-assessment questionnaire. Sixty-four PD patients exhibiting neuropsychiatric symptoms were selected for the controlled study and randomly grouped into treatment and control groups. The treatment group received BoNT/A injections, while the control group received a placebo. The primary outcome measures included depression scores from the CMI and the proportion of patients displaying improvement in neuropsychiatric symptoms at 8weeks post-treatment. The secondary outcome was other CMI scores at 4, 8, and 12weeks post-treatment. The outcomes revealed that PD patients had significantly higher scores in various neuropsychiatric factors compared to healthy controls. At 4weeks post-treatment, the treatment group displayed improvements in depression and tension. At 8 weeks post-treatment, they exhibited significant reductions in depression, anxiety, sensitivity, and tension compared to the control group. Moreover, a notably higher percentage of patients in the treatment group showed improvement in neuropsychiatric symptoms compared to the control group. At 12weeks post-treatment, the treatment group exhibited significant improvements in somatization, depression, sensitivity, and tension. PD patients commonly experience multiple neuropsychiatric symptoms, and BoNT/A has demonstrated efficacy in alleviating these symptoms. Specifically, BoNT/A was found to effectively alleviate somatization, tension, anxiety, depression, and sensitivity in PD patients.

An integrated transcription factor framework for Treg identity and diversity.

Vertebrate cell identity depends on the combined activity of scores of transcription factors (TF). While TFs have often been studied in isolation, a systematic perspective on their integration has been missing. Focusing on FoxP3+ regulatory T cells (Tregs), key guardians of immune tolerance, we combined single-cell chromatin accessibility, machine learning, and high-density genetic variation, to resolve a validated framework of diverse Treg chromatin programs, each shaped by multi-TF inputs. This framework identified previously unrecognized Treg controllers (Smarcc1) and illuminated the mechanism of action of FoxP3, which amplified a pre-existing Treg identity, diversely activating or repressing distinct programs, dependent on different regulatory partners. Treg subpopulations in the colon relied variably on FoxP3, Helios+ Tregs being completely dependent, but RORγ+ Tregs largely independent. These differences were rooted in intrinsic biases decoded by the integrated framework. Moving beyond master regulators, this work unravels how overlapping TF activities coalesce into Treg identity and diversity.

Proteomic Correlates and Prognostic Significance of Kidney Injury in Heart Failure With Preserved Ejection Fraction.

Kidney disease is common in heart failure with preserved ejection fraction (HFpEF). However, the biologic correlates and prognostic significance of kidney injury (KI), in HFpEF, beyond the estimated glomerular filtration rate (eGFR), are unclear. Using baseline plasma samples from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) trial, we measured the following KI biomarkers: cystatin-C, fatty acid-binding protein-3, Beta-2 microglobulin, neutrophil gelatinase-associated lipocalin, and kidney-injury molecule-1. Factor analysis was used to extract the common variability underlying these biomarkers. We assessed the relationship between the KI-factor score and the risk of death or HF-related hospital admission in models adjusted for the Meta-Analysis Global Group in Chronic Heart Failure risk score and eGFR. We also assessed the relationship between the KI factor score and ~5000 plasma proteins, followed by pathway analysis. We validated our findings among HFpEF participants in the Penn Heart Failure Study. KI was associated with the risk of death or HF-related hospital admission independent of the Meta-Analysis Global Group in Chronic Heart Failure risk score and eGFR. Both the risk score and eGFR were no longer associated with death or HF-related hospital admission after adjusting for the KI factor score. KI was predominantly associated with proteins and biologic pathways related to complement activation, inflammation, fibrosis, and cholesterol homeostasis. KI was associated with 140 proteins, which reproduced across cohorts. Findings regarding biologic associations and the prognostic significance of KI were also reproduced in the validation cohort. KI is associated with adverse outcomes in HFpEF independent of baseline eGFR. Patients with HFpEF and KI exhibit a plasma proteomic signature indicative of complement activation, inflammation, fibrosis, and impaired cholesterol homeostasis.

Prognostic Significance and Biologic Associations of Senescence-Associated Secretory Phenotype Biomarkers in Heart Failure.

The role of cellular senescence in human heart failure (HF) remains unclear. The senescence-associated secretory phenotype (SASP) is composed of proteins released by senescent cells. We assessed the prognostic significance and biologic pathways associated with the SASP in human HF using a plasma proteomics approach. We measured 25 known SASP proteins among 2248 PHFS (Penn HF Study) participants using the SOMAScan V4 assay. We extracted the common variance in these proteins to generate SASP factor scores and assessed the relationship between these SASP factor scores and (1) all-cause death and (2) the composite of death or HF hospital admission. We also assessed the relationship of each SASP factor to 4746 other proteins, correcting for multiple comparisons, followed by pathway analyses. Two SASP factors were identified. Both factors were associated with older age, lower estimated glomerular filtration rate, and more advanced New York Heart Association class, among other clinical variables. Both SASP factors exhibited a significant positive association with the risk of death independent of the Meta-Analysis of Global-Group in Chronic HF score and NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels. The 2 identified SASP factors were associated with 1201 and 1554 proteins, respectively, belonging to various pathways including the coagulation system, complement system, acute phase response signaling, and retinoid X receptor-related pathways that regulate cell metabolism. Increased SASP components are independently associated with adverse outcomes in HF. Biologic pathways associated with SASP are predominantly related to coagulation, inflammation, and cell metabolism.

Symptom Dimensions and Cognitive Impairments in Individuals at Clinical High Risk for Psychosis

BackgroundUnderstanding the intricate relationships between symptom dimensions, clusters, and cognitive impairments is crucial for early detection and intervention in individuals at clinical high risk for psychosis. This study delves into this complex interplay in a clinical high risk sample with the aim of predicting the conversion to psychosis. MethodsA comprehensive cognitive assessment was performed in 744 clinical high risk individuals. The study included a 3-year follow-up period to allow assessment of conversion to psychosis. Symptom profiles were determined using the Structured Interview for Prodromal Syndromes. By applying factor analysis, symptom dimensions were categorized as dominant negative symptoms (NSs), positive symptoms-stressful, and positive symptoms-odd. The factor scores were used to define 3 dominant symptom groups. Latent class analysis (LCA) and factor mixture model (FMM) were employed to identify discrete clusters based on symptom patterns. The 3-class solution was chosen for the LCA and FMM analysis. ResultsIndividuals in the dominant NS group exhibited significantly higher conversion rates to psychosis than those in the other groups. Specific cognitive variables, including performance on the Brief Visuospatial Memory Test–Revised (odds ratio = 0.702, p = .001) and Neuropsychological Assessment Battery Mazes Test (odds ratio = 0.776, p = .024), significantly predicted conversion to psychosis. Notably, cognitive impairments associated with NSs and positive symptoms-stressful affected different cognitive domains. LCA and FMM cluster 1, which was characterized by severe NSs and positive symptoms-odd, exhibited more impairments in cognitive domains than other clusters. No significant difference in the conversion rate was observed among the LCA and FMM clusters. ConclusionsThese findings highlight the importance of NSs in the development of psychosis and suggest specific cognitive domains that are affected by symptom dimensions.

Preliminary Validation of Measures of Experienced, Perceived, and Internalized Stigma Among Adults Who Are d/Deaf or Hard of Hearing in the United States and Ghana.

In this article, we examine the psychometric performance of 3 scales measuring experienced, perceived, and internalized d/Deaf or hard of hearing (d/DHH) stigma among adult (18 and older) populations of individuals who are d/DHH, including those who have been d/DHH since before they developed language (lifelong) and those who became d/DHH after they developed language (acquired) in the United States and Ghana. The preliminary validation study took place in the Greater Accra and Eastern regions of Ghana and across the United States. In the United States, all data were collected online via self-administered surveys in English. In Ghana, trained interviewers who are d/DHH and fluent in Ghanaian Sign Language conducted interviews with participants who are lifelong d/DHH using a video survey. Ghanaian participants with acquired d/DHH status were surveyed by trained hearing interviewers. We calculated polychoric correlation matrices between the measures to remove redundant and unrelated items and used exploratory factor analysis to create the final scales. We also tested the association between the factor scores and a simple summing method for calculating the scale. The study sample included people who have been d/DHH since before they developed language (Ghana: n = 171, United States n = 100) and people who became d/DHH after they developed language (Ghana: n = 174, United States: n = 219). The final experienced, perceived, and internalized scales included six, seven, and five items, respectively. All three scales performed well as unidimensional measures across all four samples. Across the four samples, the experienced, perceived, and internalized stigma scales yielded ordinal αs ranging from 0.725 to 0.947, 0.856 to 0.935, and 0.856 to 0.935, respectively. It would be acceptable to operationalize all stigma scales as sum-of-item scores. The scales performed well and appear to provide a valid means of measuring different types of stigma among diverse groups of people who are d/DHH. Future work should refine and validate these scales in additional contexts.

O105 ISOLATED NOCTURNAL HYPERTENSION AND TARGET ORGAN INJURY IN YOUTH

Background and Objective: New American Heart Association (AHA) recommendations in 2022 for pediatric ambulatory blood pressure monitoring (ABPM) established static blood pressure (BP) cutoffs to define hypertension with an optimal sensitivity-specificity balance to best capture target organ injury (TOI). This increased the prevalence of ABPM hypertension, specifically isolated nocturnal hypertension. We utilized ABPM data from the SHIP-AHOY cohort to describe the epidemiology of INH in youth and to evaluate associations between INH and TOI. Methods: We defined INH as wake BP &lt;130/80 mmHg and sleep BP &gt;110/65 mmHg. INH was also evaluated by the 2014 AHA definition: wake BP &lt;95th percentile with sleep BP &gt;95th percentile. Primary outcome was left ventricular hypertrophy (LVH), defined as left ventricular mass index &gt;38.6 g/m2.7. Cardiovascular risk factor (CVRF) scores described the number of risk factors for cardiovascular disease (dyslipidemia, obesity, hypertension by clinic systolic BP, insulin resistance) fro each participant. Logistic regression models assessed the association of INH with LVH, adjusted for age, sex, CVRF score, and ABPM tolerability. Results: Of 397 participants, 77 had INH, mostly (62%) due to elevated systolic BPs only. Median age and height were higher in INH than normotension (16.1 v 15.1 years, P=0.022) (height z-score 1.13 v 0.23, P=0.039). Other characteristics did not differ significantly between groups (Table 1). Estimated glomerular filtration rate was lower in INH. Among those with INH, 27% (N=19/71) had LVH, a greater proportion than found with 2014 definitions (21%, N=7/33). Children with INH had 2.61-fold adjusted odds of LVH compared to normotension (95%CI [1.20,5.69], P=0.016). Conclusions: Over 20% of the SHIP-AHOY cohort had INH, accounting for &gt;1/3 of hypertension overall. INH was associated with older age and taller height, mostly due to systolic BP. Compared to 2014 guidelines, the 2022 definition of INH captured a higher prevalence of LVH. INH was independently associated with increased odds of LVH. Future studies should follow children with INH longitudinally for potential development of daytime hypertension.

Abstract MP24: Relationship of Socioeconomic Position on Incident Hypertension-related Hospitalization and Blood Pressure Control among participants in the Coronary Artery Risk Development in Young Adults (CARDIA)

Background: Hypertension hospitalization, defined as being admitted to the hospital with a primary diagnosis of hypertension, has been increasing among US adults. Individuals with low socioeconomic position have higher rates of uncontrolled blood pressure (BP). We evaluated the relationship of socioeconomic position on incident hypertension hospitalization and BP control rates following hospitalization. Methods: We analyzed data from CARDIA, a prospective cohort that enrolled 5,115 adults (2,637 self-identified Black and 2,478 White adults) 18 to 30 years old from 4 urban US areas in 1985-1986. Hypertension hospitalizations were ascertained by manual chart review over 34 years of annual follow-up. We compared the incidence rate of hypertension hospitalization and prevalence of uncontrolled BP, systolic/diastolic BP ≥140/90 mm Hg, at the study visit after hospitalization by socioeconomic position. Socioeconomic position included education, income, insurance status and neighborhood deprivation factor score at the last visit before hypertension hospitalization or last CARDIA visit attended for participants who were not hospitalized. Results: Overall, 67 CARDIA participants (1.3%) were hospitalized for hypertension. Participants hospitalized for hypertension had a median age of 47 years at time of hospitaliization, 51% were male, and 87% were Black. Among those hospitalized for hypertension, 12% had less than high school education, 44% had a family income &lt; $25,000, 30% were on Medicaid or Medicare, and 58% lived in a socially deprived neighborhood. The risk of hypertension hospitalization was higher for participants with less education and who lived in more socially deprived neighborhoods ( Table 1 ). At the first study visit following hospital discharge, 67% of participants had uncontrolled BP and there was no difference by socioeconomic position. Conclusion: The incidence rate of hypertension hospitalization was higher among people with low socioeconomic position. Uncontrolled BP was common following hypertension hospitalization.

Associations Between Cardiovascular Health (Life's Essential 8) and Mental Disorders.

Mental health was closely associated with cardiovascular disease (CVD). We aimed to investigate the association between cardiovascular health (CVH), as defined by Life's Essential 8 (LE8), and the presence of depression and anxiety. We hypothesized that CVH, as defined by LE8, was negatively associated with the prevalence of depression and anxiety. A cross-sectional study was conducted on participants (≥ 20 years old) from the National Health and Nutrition Examination Survey (NHANES). The LE8 score (ranging from 0 to 100) was composed of the health behavior score and the health factor score, which were further categorized into three levels as follows: low (0-49), moderate (50-79), and high (80-100). Weighted multivariable logistic regressions and restricted cubic splines were utilized to assess the association between LE8 and mental disorders. Among the 13 028 participants included in this research, 1206 were determined to have depression symptoms and 2947 were determined to have anxiety symptoms. In the weighted and adjusted model, LE8 was negatively associated with the prevalence of depression (odds ratio [OR], 95% confidence interval [CI]: 0.61, 0.58-0.65) and anxiety (OR, 95% CI: 0.78, 0.75-0.81). Furthermore, a nonlinear dose-response relationship was observed between LE8 and anxiety. CVH defined by the LE8 was independently and negatively associated with the prevalence of depression and anxiety. Interventions targeting LE8 components may improve both CVH and mental health.

The relative age effect in selection of ab initio pilots–Revisiting Gladwell's famous claims

A relative age effect (RAE) has been found in education and sports, with students born earlier in the school year attaining higher levels of success. This was brought into public consciousness through Malcom Gladwell's Outliers: The Story of Success. However, the effect has not been thoroughly examined in other contexts. Thus, with regards to the context dependency of the RAE, and the specificity of which abilities it affects, there are unknowns. The aim of the present study was to scrutinize the tests in use in commercial aviation and explore whether there is a bias based on birthdate in competitive selection procedures assessing operational and cognitive abilities, outside of traditional education. Potential suboptimal selection has implications for flight safety. Associations were studied between relative age and test scores (of cognitive ability, manual spatial ability, and multitasking ability), as well as acceptance for higher education in commercial aviation in Sweden, in 1113 ab initio candidates. Relative age neither had a significant correlation with any of the six performance scores, nor with an aggregated factor score (r = −0.009, p = 0.791), nor predicted flight-school admission (b = 0.036, p = 0.210). Chronological age was associated with manual spatial ability, yet neither correlated with aggregate score nor with admission. The results may be an indication of the RAE having faded in early adulthood, and/or that indirect exposure of education does not benefit candidates in operational tests in early adulthood. Thus, neither relative age nor chronological age seemed to bias the results. For the effects of RAE to persist– or occur in operational abilities– competition between candidates in selection and subsequent relevant exposure (e.g., training/schooling), may be needed. Overall cognitive ability is likely more predictive of success when variance in specific enhancing exposure is limited.

Evidence of interrelated cognitive-like capabilities in large language models: Indications of artificial general intelligence or achievement?

Large language models (LLMs) are advanced artificial intelligence (AI) systems that can perform a variety of tasks commonly found in human intelligence tests, such as defining words, performing calculations, and engaging in verbal reasoning. There are also substantial individual differences in LLM capacities. Given the consistent observation of a positive manifold and general intelligence factor in human samples, along with group-level factors (e.g., crystallised intelligence), we hypothesized that LLM test scores may also exhibit positive inter-correlations, which could potentially give rise to an artificial general ability (AGA) factor and one or more group-level factors. Based on a sample of 591 LLMs and scores from 12 tests aligned with fluid reasoning (Gf), domain-specific knowledge (Gkn), reading/writing (Grw), and quantitative knowledge (Gq), we found strong empirical evidence for a positive manifold and a general factor of ability. Additionally, we identified a combined Gkn/Grw group-level factor. Finally, the number of LLM parameters correlated positively with both general factor of ability and Gkn/Grw factor scores, although the effects showed diminishing returns. We interpreted our results to suggest that LLMs, like human cognitive abilities, may share a common underlying efficiency in processing information and solving problems, though whether LLMs manifest primarily achievement/expertise rather than intelligence remains to be determined. Finally, while models with greater numbers of parameters exhibit greater general cognitive-like abilities, akin to the connection between greater neuronal density and human general intelligence, other characteristics must also be involved.

Eating Behaviors and Its Determinants: A Cross-Sectional Study In Autistic and Non-Autistic Children

Aim: Autism has increased globally, and it impacts nutrition. Factors related to mealtime behaviors of autistic children are understudied, especially in low-and-middle-income countries. Thus, this study aims to compare the eating and mealtime behaviours of autistic children (n=60) with a non-autistic sample (n=62) from Istanbul, Türkiye. Material and Methods: Parents were asked to complete a face-to-face questionnaire that included Children's Eating Behavior Inventory (CEBI) and anthropometric measures. MANCOVAs were used for comparing factors scores of CEBI between autistic and non-autistic participants by adjusting for potential covariates. Results: “Child’s Positive Eating Behavior” and “Adverse conditions in terms of child at the mealtime” (such as vomiting and choking) factors differed significantly depending on the autism status although negative eating behaviors during and after the mealtime were present in both groups. No statistically significant differences were found between the autism and comparison group on BMI percentile along with age and sex of the children. Conclusion: Our results highlight the need for evaluating the nutrition status of children at every age by not only using anthropometric measures and dietary intake, but also assessing eating behaviors. Families could be guided on regulating their children's nutritional behaviors by focusing on development of positive attitudes.

Nurses during war: Profiles-based risk and protective factors.

Nurses in southern Israel's public hospitals were exposed to unusual traumatic events following the October 7, 2023, Hamas attack on Israel, and the ensuing Swords of Iron War. This study aimed to clarify the complexity of wartime nursing by identifying profiles based on risk factors (i.e., psychological distress and adjustment disorders) and protective factors (i.e., positive affect (PA), resilience, and perceived social support [PSS]). This study utilizes a cross-sectional design. Two hundred nurses at a major public hospital in southern Israel completed self-report questionnaires. A latent profile analysis (LPA) was conducted to identify distinct profiles based on nurses' risk and protective factors. Differences in profiles were examined alongside sociodemographic and occupational variables and traumatic event exposure. The LPA was conducted using MPlus 8.8 Structural Equation Modeling (SEM) software. Two distinct profiles were identified: "reactive" and "resilient." The "reactive" group included nurses who had higher risk factor scores (psychological distress and adjustment disorder), whereas the "resilient" group included nurses who had higher protective factor scores (PA, resilience, and PSS). Furthermore, nurses in the "reactive" group were younger, with greater seniority, worse self-rated health, and a higher frequency of kidnapped family members compared to nurses from the "resilient" group. Nurses in wartime are at risk if identified as "reactive." Identifying these profiles can assist in developing effective support practices to help nurses cope with wartime challenges and maintain their mental well-being. Healthcare organizations should tailor interventions to prepare and support nurses of various ages and experience levels, during and after conflicts. This approach aims to reduce risk factors and promote protective factors among nurses during wartime.

Anhedonia is associated with higher functional connectivity between the nucleus accumbens and paraventricular nucleus of thalamus

BackgroundAnhedonia stands as a life-threatening transdiagnostic feature of many mental illnesses, most notably major depression and involves neural circuits for processing reward information. The paraventricular nucleus of the thalamus (PVT) is associated with reward-seeking behavior, however, links between the PVT circuit and anhedonia have not been investigated in humans. MethodsIn a sample of adults with and without psychiatric symptoms (n = 75, 18–41 years, 55 female), we generated an anhedonia factor score for each participant using a latent factor analysis, utilizing data from depression and anxiety assessments. Functional connectivity between the PVT and the nucleus accumbens (NAc) was calculated from high-resolution (1.5 mm) resting state fMRI. ResultsAnhedonia factor scores showed a positive relationship with functional connectivity between the PVT and the NAc, principally in males and in those with psychiatric symptoms. In males, connectivity between other midline thalamic nuclei and the NAc did not show these relationships, suggesting that this link may be specific to PVT. LimitationsThis cohort was originally recruited to study depression and not anhedonia per se. The distribution of male and female participants in our cohort was not equal. Partial acquisition in high-resolution fMRI scans restricted regions of interest outside of the thalamus and reward networks. ConclusionsWe report evidence that anhedonia is associated with enhanced functional connectivity between the PVT and the NAc, regions that are relevant to reward processing. These results offer clues as to the potential prevention and prevention and treatment of anhedonia.
