Conceptualization and characterization of "primary" and "secondary" cognitive impairment in schizophrenia

Cognitive impairment represents one of the core features of schizophrenia, involves both neurocognition and social cognition domains, and has a significant negative impact on real-world functioning. The present review provides a framework for the conceptualization and characterization of "primary" and "secondary" cognitive impairment in schizophrenia. In this conceptualization, primary cognitive impairment can be defined as a consequence of the neurobiological alterations that underlie psychopathological manifestations of the disorder, while secondary cognitive impairment can be defined as the results of a source issue that has a negative impact on cognitive performance. Sources of secondary cognitive impairment are frequent in people with schizophrenia and include several different factors, such as positive and negative symptoms, depressive symptoms, autistic symptoms, pharmacotherapy, substance abuse, metabolic syndrome, social deprivation, and sleep disorders. It can be hypothesized that secondary cognitive impairment may be improved by effectively resolving the source issue, while primary cognitive impairment may benefit from dedicated treatment. Further research is required to confirm this hypothesis, to better characterize the distinction between primary and secondary cognitive impairment in a clinical and in a neurobiological perspective, and to evaluate the impact of systematically assessing and treating secondary cognitive impairment.

Aerobic exercise improves cognitive flexibility and modulates regional volume changes in a rat model of autism

Gestational exposure to valproic acid (VPA) is a risk factor for autism spectrum disorder (ASD). Rodents exposed to VPA in utero display common features of ASD, including volumetric dysregulation in higher-order cognitive regions like the medial prefrontal cortex (mPFC), the anterior cingulate cortex (ACC), and the hippocampus. Exercise has been shown in elderly populations to boost cognition and to buffer against brain volume losses with age. This study employed an adolescent treadmill exercise intervention to facilitate cognitive flexibility and regional brain volume regulation in rats exposed to VPA during gestation. It was found that exercise improved performance on extra-dimensional shifts of attention on a set-shifting task, which is indicative of improved cognitive flexibility. Exercise decreased frontal cortex volume in females, whereas in males exercise increased the ventral hippocampus. These findings suggest that aerobic exercise may be an effective intervention to counteract the altered development of prefrontal and hippocampal regions often observed in ASD.

The study found a statistically significant increase in the mean scores of resilience, self-esteem, and spirituality (p < .001 each) following the spiritual adaptation of CBT sessions compared to the control group. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The findings can guide psychiatrists and nurses in providing more comprehensive and effective care to patients with OUD by incorporating a spiritual adaptation of CBT with spiritual components into treatment plans.

ABSTRACT

INTRODUCTION: Opioid use disorder (OUD) is a prevalent problem among Egyptian youth, and achieving recovery and abstinence is challenging. Cognitive behavioural therapy (CBT), a well-known approach, can be particularly beneficial when it addresses psychological aspects such as resilience, self-esteem and spirituality.

AIM

This study aimed to evaluate the effectiveness of a spiritual adaptation of CBT in enhancing these factors among clients with OUD.

METHODS

A quasi-experimental study with a control group was conducted using a pretest-posttest design. The study included 49 clients with OUD and 46 clients in the control group. The Rosenberg Self-Esteem Scale-Modified Arabic Version, Daily Spiritual Experience Scale, and the Connor-Davidson Resilience Scale were used as measurement tools. CBT was delivered in 60-min group sessions. After 3 months, the questionnaires were re-administered to evaluate the effectiveness of a spiritual adaptation of CBT sessions.

RESULTS

The study found a statistically significant increase in the mean scores of resilience, self-esteem and spirituality (p < .001 each) following a spiritual adaptation of CBT sessions compared to the control group.

DISCUSSION

A spiritual adaptation of CBT effectively enhanced resilience, self-esteem and spirituality in clients with OUD.

IMPLICATIONS FOR PRACTICE

Understanding the effectiveness of a spiritual adaptation of CBT in enhancing resilience, self-esteem and spirituality can enable psychiatrists and nurses to provide more comprehensive and effective care to patients with OUD.

Structure-function coupling in macroscale human brain networks

Precisely how the anatomical structure of the brain gives rise to a repertoire of complex functions remains incompletely understood. A promising manifestation of this mapping from structure to function is the dependency of the functional activity of a brain region on the underlying white matter architecture. Here, we review the literature examining the macroscale coupling between structural and functional connectivity, and we establish how this structure-function coupling (SFC) can provide more information about the underlying workings of the brain than either feature alone. We begin by defining SFC and describing the computational methods used to quantify it. We then review empirical studies that examine the heterogeneous expression of SFC across different brain regions, among individuals, in the context of the cognitive task being performed, and over time, as well as its role in fostering flexible cognition. Last, we investigate how the coupling between structure and function is affected in neurological and psychiatric conditions, and we report how aberrant SFC is associated with disease duration and disease-specific cognitive impairment. By elucidating how the dynamic relationship between the structure and function of the brain is altered in the presence of neurological and psychiatric conditions, we aim to not only further our understanding of their aetiology but also establish SFC as a new and sensitive marker of disease symptomatology and cognitive performance. Overall, this Review collates the current knowledge regarding the regional interdependency between the macroscale structure and function of the human brain in both neurotypical and neuroatypical individuals.

The mediating and moderating effects of psychological distress on the relationship between social media use with perceived social isolation and sleep quality of late middle-aged and older adults

OBJECTIVES

Older adults are more likely to have poor sleep quality and be socially isolated. The present study examined the potential benefits and disadvantages of social media use (SMU) with respect to sleep quality and perceived social isolation among Iranian late-middle-aged and older adults with focus a on both the mediating and moderating role of psychological distress.

METHODS

A population-based cross-sectional study was conducted among 900 older community-dwellers living in Shiraz using a structured questionnaire. Social media use was assessed by estimating the frequency of social networking site visits per week. Data concerning self-rated physical health, chronic medical and mental health conditions, perceived social isolation, sleep quality, and psychological distress were also collected. Multiple linear regression was used to identify independent variables associated with outcomes. Then, mediation and moderation models were used to examine the potential mediating and moderating effects of psychological distress and SMU on their relationships with the study variables.

RESULTS

Higher social media use was associated with better sleep quality and less perceived social isolation. Nevertheless, the relationships between SMU and participants' sleep quality and perceived social isolation were largely mediated by their level of psychological distress. Furthermore, SMU had a significant moderating effect in the relationship between the psychological distress and the levels of perceived social isolation, so that participants with higher frequency of SMU per week felt less loneliness.

CONCLUSIONS

The study findings suggest that SMU has a positive buffering effect regarding late middle-aged and older adults' mental health mainly through moderation of their perceived social isolation. The mediating role of psychological distress in research examining the relationship between SMU and older adults' mental health outcomes should be considered in future research.

Neuroendocrinology of bone

The past decade has witnessed significant advances in our understanding of skeletal homeostasis and the mechanisms that mediate the loss of bone in primary and secondary osteoporosis. Recent breakthroughs have primarily emerged from identifying disease-causing mutations and phenocopying human bone disease in rodents. Notably, using genetically-modified rodent models, disrupting the reciprocal relationship with tropic pituitary hormone and effector hormones, we have learned that pituitary hormones have independent roles in skeletal physiology, beyond their effects exerted through target endocrine glands. The rise of follicle-stimulating hormone (FSH) in the late perimenopause may account, at least in part, for the rapid bone loss when estrogen is normal, while low thyroid-stimulating hormone (TSH) levels may contribute to the bone loss in thyrotoxicosis. Admittedly speculative, suppressed levels of adrenocorticotropic hormone (ACTH) may directly exacerbate bone loss in the setting of glucocorticoid-induced osteoporosis. Furthermore, beyond their established roles in reproduction and lactation, oxytocin and prolactin may affect intergenerational calcium transfer and therefore fetal skeletal mineralization, whereas elevated vasopressin levels in chronic hyponatremic states may increase the risk of bone loss.. Here, we discuss the interaction of each pituitary hormone in relation to its role in bone physiology and pathophysiology.

Gut Microbiota and Autism Spectrum Disorder: A Neuroinflammatory Mediated Mechanism of Pathogenesis?

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social communication and behavior, frequently accompanied by restricted and repetitive patterns of interests or activities. The gut microbiota has been implicated in the etiology of ASD due to its impact on the bidirectional communication pathway known as the gut-brain axis. However, the precise involvement of the gut microbiota in the causation of ASD is unclear. This study critically examines recent evidence to rationalize a probable mechanism in which gut microbiota symbiosis can induce neuroinflammation through intermediator cytokines and metabolites. To develop ASD, loss of the integrity of the intestinal barrier, activation of microglia, and dysregulation of neurotransmitters are caused by neural inflammatory factors. It has emphasized the potential role of neuroinflammatory intermediates linked to gut microbiota alterations in individuals with ASD. Specifically, cytokines like brain-derived neurotrophic factor, calprotectin, eotaxin, and some metabolites and microRNAs have been considered etiological biomarkers. We have also overviewed how probiotic trials may be used as a therapeutic strategy in ASD to reestablish a healthy balance in the gut microbiota. Evidence indicates neuroinflammation induced by dysregulated gut microbiota in ASD, yet there is little clarity based on analysis of the circulating immune profile. It deems the repair of microbiota load would lower inflammatory chaos in the GI tract, correct neuroinflammatory mediators, and modulate the neurotransmitters to attenuate autism. The interaction between the gut and the brain, along with alterations in microbiota and neuroinflammatory biomarkers, serves as a foundational background for understanding the etiology, diagnosis, prognosis, and treatment of autism spectrum disorder.

Ketamine for catatonia: A novel treatment for an old clinical challenge? A systematic review of the evidence

INTRODUCTION

Catatonia, documented since the 19th century, remains a significant challenge in terms of recognition and treatment. Over the last two decades, ketamine has brought new perspectives to psychiatry, sparking widespread interest. Concurrently, catatonia has attracted heightened scientific attention. Preliminary evidence suggests the therapeutic potential of ketamine for catatonia.

METHODS

We systematically searched Medline/PubMed, Embase, PsycINFO, Lilacs, and Cochrane Library databases, as well as Google Scholar, for studies with ketamine or its enantiomers as intervention for catatonia, with no restrictions to underlying diagnosis, date, language, or study design.

RESULTS

Twenty articles were included, encompassing a total of 25 catatonic patients receiving ketamine or esketamine. Predominantly female (61.9 %), with a mean age of 44.4 years, patients mostly exhibited manifestations compatible with the retarded subtype of catatonia. Mood disorders were the most prevalent underlying diagnoses. Ketamine was primarily administered intravenously over a 40-minute period and in multiple-dosing schemes. Mean response and remission rates of catatonic manifestations for the whole sample were 80 % and 44 %, respectively, with no reports of worsening catatonic features or psychotic symptoms. Only one patient discontinued treatment due to intolerable dissociative effects.

CONCLUSION

Challenging the conventional contraindication of ketamine in psychotic disorders, current evidence highlights its potential efficacy, particularly in treating catatonia. Pending further research, we advocate reevaluating this contraindication, as it may offer a promising therapeutic option, especially for challenging cases. Preliminary evidence suggests potentially greater benefits for catatonic patients with underlying mood disorders compared to primary psychotic disorders.

Association of social gatherings and physical exercise with depressive symptoms among middle-aged and older adults during the COVID-19 pandemic

Strict social isolation and physical distancing measures implemented during the COVID-19 pandemic had significant implications for the psychological well-being of middle-aged and older adults. This study aimed to investigate factors associated with depressive symptoms during the pandemic period among individuals who reported no significant depressive symptoms before the pandemic. Individuals from the Korean Longitudinal Study of Aging without a previous report of significant depressive symptoms across Waves 6 (2016) and 7 (2018) were investigated for the development of depressive symptoms in Wave 8 (2020). The multivariable logistic regression results revealed that both men and women who participated in social gatherings and physical exercise less than once a week were associated with an increase in the likelihood of depressive symptoms (odds ratio [OR] 2.88; 95% confidence interval [CI] 1.80-4.61 and OR 2.61; 95% CI 1.64-4.15, respectively for men and OR 2.58; 95% CI 1.80-3.70 and OR 1.51; 95% CI 1.02-2.23, respectively for women). In addition, unmarried men (OR 2.38; 95% CI 1.37-4.14) and women with one chronic disease (OR 1.98; 95% CI 1.14-3.43) or two or more chronic diseases (OR 2.28; 95% CI 1.31-3.99) reported a significant increase in the likelihood of depressive symptoms. Regular social gatherings and physical exercise were identified as key factors in mitigating depressive symptoms among middle-aged and older adults. The findings can inform the development of public health strategies that promote regular social interactions and physical activity to enhance the psychological resilience and overall well-being of middle-aged and older adults in the endemic era.

Impact of Spiritual Support Interventions on the Quality of Life of Patients Who Receive Palliative Care: A Systematic Review

BACKGROUND

Palliative care focuses on the prevention of worsening health, improving the quality of the patient's life, and the relief of suffering, and therefore has a considerable impact on both the patient suffering from a life-threatening or potentially life-threatening illness and on their family. Spirituality, as the dimension of human life involving the search for meaning, purpose, and transcendence, and connection with oneself, others, and the sacred, could be essential in supporting these patients. The aim of this study was to synthesise the scientific evidence describing the interventions and/or activities undertaken to meet the spiritual needs of the palliative patient.

METHODS

A literature search was carried out across the following databases: PubMed, LILACS, Scopus, and Web of Science. The PRISMA statement was used to guide this review.

RESULTS

Twenty-four articles were included. The thematic categories included spiritual needs at the end of life, the influence of music and dance as palliative care, care for family caregivers, and the comparison between counselling and dignity therapy.

CONCLUSIONS

Interventions in the biopsychosocial-spiritual spheres impact on the patient's peace of mind and promote the acceptance of a "good death". Healthcare personnel play an essential role in the way their patients prepare for the moment of death, and the meaning and values they convey help them to accompany and welcome patients. Last but not least, universities can play a crucial role by training nurses to integrate spiritual interventions such as music and dance, or by considering the family as a unit of care. The systematic review protocol was registered in the Prospective International Register of Systematic Reviews (PROSPERO) under protocol number CRD42023490852.

Expert consensus on multilevel implementation hypotheses to promote the uptake of youth care guidelines: a Delphi study

BACKGROUND

The implementation of youth care guidelines remains a complex process. Several evidence-based frameworks aid the identification and specification of implementation determinants and strategies. However, the influence of specific strategies on certain determinants remains unclear. Therefore, we need to clarify which active ingredients of strategies, known as behaviour change techniques (BCTs), elicit behaviour change and improve implementation outcomes. With this knowledge, we are able to formulate evidence-based implementation hypotheses. An implementation hypothesis details how determinants and in turn, implementation outcomes might be influenced by specific implementation strategies and their BCTs. We aimed to identify (1) determinants relevant to the implementation of youth care guidelines and (2) feasible and potentially effective implementation hypotheses.

METHODS

A four-round online modified Delphi study was conducted. In the first round, experts rated the implementation determinants based on their relevance. Next, experts formulated implementation hypotheses by connecting BCTs and implementation strategies to determinants and were asked to provide a rationale for their choices. In round three, the experts reconsidered and finalised their hypotheses based on an anonymous overview of all formulated hypotheses, including rationales. Finally, the experts rated the implementation hypotheses based on their potential effectiveness and feasibility.

RESULTS

Fourteen experts completed the first, second, and third rounds, with 11 completed the final round. Guideline promotion, mandatory education, presence of an implementation leader, poor management support, knowledge regarding guideline use, and a lack of communication skills were reported as most relevant determinants. In total, 46 hypotheses were formulated, ranging from 6 to 9 per determinant. For each determinant, we provide an overview of the implementation hypotheses that were most commonly deemed feasible and potentially effective.

CONCLUSION

This study offers valuable insights into youth care guideline implementation by systematically identifying relevant determinants and formulating hypotheses based on expert input. Determinants related to engagement and to knowledge and skills were found to be relevant to youth care guideline implementation. This study offers a set of hypotheses that could help organisations, policymakers, and professionals guide the implementation process of youth care guidelines to ultimately improve implementation outcomes. The effectiveness of these hypotheses in practice remains to be assessed.

Reduced spatial frequency differentiation and sex-related specificities in fearful face detection in autism: Insights from EEG and the predictive brain model

Face processing relies on predictive processes driven by low spatial frequencies (LSF) that convey coarse information prior to fine information conveyed by high spatial frequencies. However, autistic individuals might have atypical predictive processes, contributing to facial processing difficulties. This may be more normalized in autistic females, who often exhibit better socio-communicational abilities than males. We hypothesized that autistic females would display a more typical coarse-to-fine processing for socio-emotional stimuli compared to autistic males. To test this hypothesis, we asked adult participants (44 autistic, 51 non-autistic) to detect fearful faces among neutral faces, filtered in two orders: from coarse-to-fine (CtF) and from fine-to-coarse (FtC). Results show lower d' values and longer reaction times for fearful detection in autism compared to non-autistic (NA) individuals, regardless of the filtering order. Both groups presented shorter P100 latency after CtF compared to FtC, and larger amplitude for N170 after FtC compared to CtF. However, autistic participants presented a reduced difference in source activity between CtF and FtC in the fusiform. There was also a more spatially spread activation pattern in autistic females compared to NA females. Finally, females had faster P100 and N170 latencies, as well as larger occipital activation for FtC sequences than males, irrespective of the group. Overall, the results do not suggest impaired predictive processes from LSF in autism despite behavioral differences in fear detection. However, they do indicate reduced brain modulation by spatial frequency in autism. In addition, the findings highlight sex differences that warrant consideration in understanding autistic females.

The Complex Relationship between Neuromodulators, Circadian Rhythms, and Insomnia in Patients with Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) has been linked to disruptions in circadian rhythm and neurotrophin (NFT) signaling. This study explored the link between neuromodulators, chronotype, and insomnia in OSA. The participants (n = 166) underwent polysomnography (PSG) before being categorized into either the control or the OSA group. The following questionnaires were completed: Insomnia Severity Index (ISI), Epworth Sleepiness Scale, Chronotype Questionnaire (morningness-eveningness (ME), and subjective amplitude (AM). Blood samples were collected post-PSG for protein level assessment using ELISA kits for brain-derived neurotrophic factor (BDNF), proBDNF, glial-cell-line-derived neurotrophic factor, NFT3, and NFT4. Gene expression was analyzed utilizing qRT-PCR. No significant differences were found in neuromodulator levels between OSA patients and controls. The controls with insomnia exhibited elevated neuromodulator gene expression (p < 0.05). In the non-insomnia individuals, BDNF and NTF3 expression was increased in the OSA group compared to controls (p = 0.007 for both); there were no significant differences between the insomnia groups. The ISI scores positively correlated with all gene expressions in both groups, except for NTF4 in OSA (R = 0.127, p = 0.172). AM and ME were predicting factors for the ISI score and clinically significant insomnia (p < 0.05 for both groups). Compromised compensatory mechanisms in OSA may exacerbate insomnia. The correlation between chronotype and NFT expression highlights the role of circadian misalignments in sleep disruptions.

Aberrant glutamatergic systems underlying impulsive behaviors: Insights from clinical and preclinical research

Impulsivity is a broad construct that often refers to one of several distinct behaviors and can be measured with self-report questionnaires and behavioral paradigms. Several psychiatric conditions are characterized by one or more forms of impulsive behavior, most notably the impulsive/hyperactive subtype of attention-deficit/hyperactivity disorder (ADHD), mood disorders, and substance use disorders. Monoaminergic neurotransmitters are known to mediate impulsive behaviors and are implicated in various psychiatric conditions. However, growing evidence suggests that glutamate, the major excitatory neurotransmitter of the mammalian brain, regulates important functions that become dysregulated in conditions like ADHD. The purpose of the current review is to discuss clinical and preclinical evidence linking glutamate to separate aspects of impulsivity, specifically motor impulsivity, impulsive choice, and affective impulsivity. Hyperactive glutamatergic activity in the corticostriatal and the cerebro-cerebellar pathways are major determinants of motor impulsivity. Conversely, hypoactive glutamatergic activity in frontal cortical areas and hippocampus and hyperactive glutamatergic activity in anterior cingulate cortex and nucleus accumbens mediate impulsive choice. Affective impulsivity is controlled by similar glutamatergic dysfunction observed for motor impulsivity, except a hyperactive limbic system is also involved. Loss of glutamate homeostasis in prefrontal and nucleus accumbens may contribute to motor impulsivity/affective impulsivity and impulsive choice, respectively. These results are important as they can lead to novel treatments for those with a condition characterized by increased impulsivity that are resistant to conventional treatments.

A bibliometric analysis of anxiety and depression among primary school students

Background

Rising anxiety and depression in primary school students adversely affect their development and academics, burdening families and schools. This trend necessitates urgent, focused research within this young demographic. This alarming trend calls for a systematic bibliometric analysis to develop effective preventative and remedial strategies.

Objectives

This study aims to identify and analyze the prevailing research hotspots and emerging trends concerning anxiety and depression in primary school students, thereby furnishing a foundational reference for future academic endeavors in this area.

Methods

This study uses the Web of Science (WOS) Core Collection database as the data source, focusing on literature published between 2013 and 2023 concerning anxiety and depression in primary school students. An initial search identified 1852 articles, which were then manually screened to exclude duplicates, conferences, announcements, and unrelated literature, resulting in 1791 relevant articles. The analysis, executed on December 31, 2023, employed CiteSpace and Vosviewer tools to assess various bibliometric indicators including authorship, country, institutional affiliations, publication trends, keyword frequency, and citation analysis.

Results

The analysis revealed a corpus of 1,791 English-language articles, with a discernible upward trend in publications over the decade. The USA and China were the leading countries in this field, with 482and 272 papers, respectively. The research predominantly addresses the etiological factors of anxiety and depression, various intervention strategies, and the comorbidities associated with these conditions in the target population. Key research focuses have been identified in areas such as suicidal thoughts, bullying in schools, the impact of COVID-19, mindfulness interventions, and anxiety related to mathematics. Future research is projected to increasingly focus on the effects of mathematics anxiety on the psychological and behavioral outcomes in students.

Conclusion

This study provides a critical visual and analytical overview of the key research areas and trends in the field of anxiety and depression among primary school students. It underscores the necessity of concentrating on the underlying causes and potential interventions. Such focused research is imperative for mitigating the mental health challenges faced by young students and enhancing their educational and developmental outcomes.

Evaluation of the pharmacodynamic interaction effect of augmentation agents with clozapine in patients with treatment-resistant schizophrenia: A simulation study of clinical data

INTRODUCTION

The aim of the study was to evaluate interaction effect of various augmentation strategies with clozapine in patients with Treatment-resistant schizophrenia.

METHODS

Data was extracted for change in positive and negative syndrome scale (PANSS) or brief psychiatric rating scale (BPRS) scores for monotherapy with various antipsychotic agents alone and their combination with clozapine. Individual patient data was generated using simulation of data (factorial trial framework) from published clinical trials for sample sizes from eight to 400 to evaluate interaction effect through linear modeling. Dose equivalents were calculated, and best fit models were determined for simulated data.

RESULTS

The polynomial model was found to be the best fit for the simulated data to determine interaction effect of combination. The clozapine augmentation with risperidone and ziprasidone was found to be antagonistic, whereas it was additive for haloperidol, aripiprazole, and quetiapine. A synergistic effect was observed for ECT combined with clozapine (Interaction effect: -7.62; p <0.001). A sample size of 250-300 may be sufficient to demonstrate a clinically significant interaction in future trials.

CONCLUSION

Clozapine may be augmented with electroconvulsive therapy, leading to the enhancement of antipsychotic effect. Though some antipsychotics like aripiprazole demonstrate additive effects, they may also add to the adverse effects.

Mechanistic studies in pathological health anxiety: A systematic review and emerging conceptual framework

BACKGROUND

Pathological health anxiety (PHA) (e.g., hypochondriasis and illness anxiety disorder) is common in medical settings and associated with increased healthcare costs. However, the psychological and neurobiological mechanisms contributing to the development and maintenance of PHA are incompletely understood.

METHODS

We performed a systematic review to characterize the mechanistic understanding of PHA. PubMed, PsycINFO, and Embase databases were searched to find articles published between 1/1/1990 and 12/31/2022 employing a behavioral task and/or physiological measures in individuals with hypochondriasis, illness anxiety disorder, and PHA more broadly.

RESULTS

Out of 9141 records identified, fifty-seven met inclusion criteria. Article quality varied substantially across studies, and was overall inadequate. Cognitive, behavioral, and affective findings implicated in PHA included health-related attentional and memory recall biases, a narrow health concept, threat confirming thought patterns, use of safety-seeking behaviors, and biased explicit and implicit affective processing of health-related information among other observations. There is initial evidence supporting a potential overestimation of interoceptive stimuli in those with PHA. Neuroendocrine, electrophysiology, and brain imaging research in PHA are particularly in their early stages.

LIMITATIONS

Included articles evaluated PHA categorically, suggesting that sub-threshold and dimensional health anxiety considerations are not contextualized.

CONCLUSIONS

Within an integrated cognitive-behavioral-affective and predictive processing formulation, we theorize that sub-optimal illness and health concepts, altered interoceptive modeling, biased illness-based predictions and attention, and aberrant prediction error learning are mechanisms relevant to PHA requiring more research. Comprehensively investigating the pathophysiology of PHA offers the potential to identify adjunctive diagnostic biomarkers and catalyze new biologically-informed treatments.

Association Between Family History of Diabetes, Irrational Beliefs, and Health Anxiety with 10-Year Risk of Type 2 Diabetes Mellitus: the ATTICA Epidemiological Study (2002-2012)

BACKGROUND

This study aimed to examine the relationship between family history of diabetes, irrational beliefs, and health anxiety in the development of type 2 diabetes mellitus (T2DM).

METHOD

ATTICA is a prospective, cohort study (2002-2012). The working sample included 845 participants (18-89 years), free of diabetes at baseline. Α detailed biochemical, clinical, and lifestyle evaluation was performed, while participants' irrational beliefs and health anxiety were assessed through the Irrational Beliefs Inventory and the Whiteley index scale, respectively. We evaluated the association between the participants' family history of diabetes mellitus with the 10-year risk of diabetes mellitus, both in the total study's sample and separately according to their levels of health anxiety and irrational beliefs.

RESULTS

The crude 10-year risk of T2DM was 12.9% (95%CI: 10.4, 15.4), with 191 cases of T2DM. Family history of diabetes was associated with 2.5 times higher odds (2.53, 95%CI 1.71, 3.75) of T2DM compared to those without family history. Among participants with family history of diabetes, the highest likelihood of developing T2DM, regarding their tested psychological features (i.e., low/high irrational beliefs in the entire group, low/high health anxiety in the entire group, and low/high irrational beliefs, low/high healthy anxiety), had people with high irrational beliefs, low health anxiety (OR 3.70, 95%CI 1.83, 7.48).

CONCLUSIONS

The findings underline the important moderating role of irrational beliefs and health anxiety in the prevention of T2DM, among participants at increased risk of T2DM.

Smaller hypothalamic subregion with paraventricular nucleus in patients with panic disorder

In panic disorder (PD), functional disturbance of the hypothalamus-pituitary-adrenal (HPA) axis has been considered. However, in neuroimaging studies of PD, the hypothalamus and pituitary gland are poorly studied.We investigated the volume of PD patients' hypothalamus and pituitary gland, enrolling 38 PD patients and 38 healthy controls. Severity of PD was mild to moderate according to the Panic Disorder Severity Scale, and the illness duration was relatively short (median = 2.8 years). The hypothalamus' gray matter was automatically extracted and segmented, whereas the pituitary gland was manually traced. Regarding the hypothalamus, the paraventricular nucleus (PVH), which produces the corticotropin-releasing hormone, was of interest.The volumes of the pituitary and the bilateral anterior-superior hypothalamic subunits, where the PVH would be located, were compared by the multiple regression analyses controlling for age and intracranial content volume. To compensate for limitation in the abovementioned segmentation and analyses, the voxel-based morphometry with small volume correction (VBM-SVC) targeting the whole hypothalamus was also performed.The multiple regression analyses did not find significant effect of PD diagnosis on the volumes. However, in the VBM-SVC analysis, volume reduction of the PVH was suggested in PD even when patients who experienced PD for ≥ 3 years were excluded [peak coordinate (x, y, z = -2, 3, -8), FWE-corrected P = .022 (cluster-level) and 0.003 (peak-level), voxel size = 63]. Our results suggested structural alteration of the PVH in PD patients for the first time, indicating importance of the HPA-axis in PD pathology.

Resident immune responses to spinal cord injury: role of astrocytes and microglia

Spinal cord injury can be traumatic or non-traumatic in origin, with the latter rising in incidence and prevalence with the aging demographics of our society. Moreover, as the global population ages, individuals with co-existent degenerative spinal pathology comprise a growing number of traumatic spinal cord injury cases, especially involving the cervical spinal cord. This makes recovery and treatment approaches particularly challenging as age and comorbidities may limit regenerative capacity. For these reasons, it is critical to better understand the complex milieu of spinal cord injury lesion pathobiology and the ensuing inflammatory response. This review discusses microglia-specific purinergic and cytokine signaling pathways, as well as microglial modulation of synaptic stability and plasticity after injury. Further, we evaluate the role of astrocytes in neurotransmission and calcium signaling, as well as their border-forming response to neural lesions. Both the inflammatory and reparative roles of these cells have eluded our complete understanding and remain key therapeutic targets due to their extensive structural and functional roles in the nervous system. Recent advances have shed light on the roles of glia in neurotransmission and reparative injury responses that will change how interventions are directed. Understanding key processes and existing knowledge gaps will allow future research to effectively target these cells and harness their regenerative potential.

Psychotomimetic compensation versus sensitization

It is a paradox that psychotomimetic drugs can relieve symptoms that increase risk of and cooccur with psychosis, such as attention and motivational deficits (e.g., amphetamines), pain (e.g., cannabis) and symptoms of depression (e.g., psychedelics, dissociatives). We introduce the ideas of psychotomimetic compensation and psychotomimetic sensitization to explain this paradox. Psychotomimetic compensation refers to a short-term stressor or drug-induced compensation against stress that is facilitated by engagement of neurotransmitter/modulator systems (endocannabinoid, serotonergic, glutamatergic and dopaminergic) that mediate the effects of common psychotomimetic drugs. Psychotomimetic sensitization occurs after repeated exposure to stress and/or drugs and is evidenced by the gradual intensification and increase of psychotic-like experiences over time. Theoretical and practical implications of this model are discussed.

Explaining the Patterns of Bullying Victimization Trajectories: Assessing the Generality of Low Self-Control and Crime Opportunity Models to Bullying Victims

This study hypothesizes that self-control and opportunity variables affect heterogeneity in developmental trajectories of bullying victimization. Using data from a follow-up study of 2,351 Korean adolescents, the study incorporates a latent class growth analysis approach to identify subgroups, each with a unique pattern of the trajectories. The model yields three subgroups of bullying victims: the early-onset and decreaser, the increaser and late-peak, and the normative groups. Results suggest that, compared to the normative group, the early-onset and decreasing group members manifest lower levels of self-control and engage in a greater range of delinquent behaviors. Also, the impact of low self-control on group membership was attenuated after controlling for those opportunity variables, indicating a partially mediating relationship. Social guardianship variables distinguished normative groups from other victim groups. Further, members of the increaser and late-peak group were more likely than the early-onset and decreaser group members to engage in cyber deviance over the long-term.

Impact of spiritual interventions in individuals with cancer: A systematic review and meta-analysis

PURPOSE

This meta-analysis aimed to determine how spiritual interventions affect cancer patients' physical, emotional, and spiritual outcomes and quality of life.

METHODS

Between 2012 and May 2024, the Cochrane Library, Scopus, PubMed, and Web of Science were searched considering the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Twenty-six randomized controlled trials were included, and 16 were synthesized in the meta-analysis. Bias risk was evaluated using the Cochrane risk-of-bias methodology for randomized studies. The Grading of Recommendations, Assessment, Development, and Evaluations tool was employed for evidence certainty. Heterogeneity was expressed through I2 and Q statistics. Hedge's g was calculated for effect sizes. Egger's and Kendall's Tau were used for publication bias.

RESULTS

Spiritual interventions yielded beneficial effects on fatigue (Hedges's g = 0.900, p < 0.001) and pain (Hedges's g = 0.670, p < 0.001) but not for overall symptom burden (Hedges's g = 0.208, p = 0.176). Significant effects were found for anxiety (Hedges's g = 0.301, p < 0.001), depression (Hedges's g = 0.175, p = 0.016), and psychological distress (Hedges's g = 0.178, p = 0.024), except for hopelessness (Hedges's g = 0.144, p = 0.091). Spiritual interventions enhanced faith (Hedges's g = 0.232, p = 0.035), the meaning of life (Hedges's g = 0.259, p = 0.002), spiritual well-being (Hedges's g = 0.268, p < 0.001), and quality of life (Hedges's g = 245, p < 0.001). Moderator analysis pointed out that cancer stage, total duration, delivery format, providers' qualification, content, and conceptual base of spiritual interventions significantly affect physical, emotional, and spiritual outcomes and quality of life.

CONCLUSION

This meta-analysis highlighted the benefits of spiritual interventions with varying effect sizes on patients' outcomes, as well as quality of life in cancer, and shed on how to incorporate these approaches into clinical practice.

Three Lessons Learned About Power and Improving Recruitment of Underrepresented Populations in Clinical Trials

This Open Forum is relevant for investigators who conduct research with historically understudied and marginalized populations. The authors introduce a U.S. Department of Veterans Affairs clinical trial that experienced challenges with recruitment of African American or Black veterans and was terminated for not achieving its recruitment goals. The role of power dynamics in clinical research is discussed, specifically how unequal distributions of power may create recruitment challenges. The authors summarize three lessons learned and offer recommendations for sharing power equitably between investigators and potential participants. By recounting these experiences, the authors seek to promote culturally sensitive, veteran-centered approaches to recruitment in future clinical trials.

Transdiagnostic Mood, Anxiety, and Trauma Symptom Factors in Alcohol Use Disorder: Neural Correlates Across 3 Brain Networks

BACKGROUND

Alcohol use disorder (AUD) is associated with high rates of trauma, mood, and anxiety disorders. Across these diagnoses, individual symptoms substantially overlap, highlighting the need for a transdiagnostic approach. Furthermore, there is limited research on how transdiagnostic psychopathology impacts the neural correlates of AUD. Thus, we aimed to identify symptom factors spanning diagnoses and examine how they relate to the neurocircuitry of addiction.

METHODS

Eighty-six veterans with AUD completed self-report measures and reward, incentive salience, and cognitive control functional magnetic resonance imaging tasks. Factor analysis was performed on self-reported trauma, depression, anxiety, and stress symptoms to obtain transdiagnostic symptom compositions. Neural correlates of a priori-defined regions of interest in the 3 networks were assessed. Independent sample t tests were used to compare the same nodes by DSM-5 diagnosis.

RESULTS

Four symptom factors were identified: Trauma distress, Negative affect, Hyperarousal, and Somatic anxiety. Trauma distress score was associated with increased cognitive control activity during response inhibition (dorsal anterior cingulate cortex). Negative affect was related to lower activation in reward regions (right caudate) but higher activation in cognitive control regions during response inhibition (left dorsolateral prefrontal cortex). Hyperarousal was related to lower reward activity during monetary reward anticipation (left caudate, right caudate). Somatic anxiety was not significantly associated with brain activation. No difference in neural activity was found by posttraumatic stress disorder, major depressive disorder, or generalized anxiety disorder diagnosis.

CONCLUSIONS

These hypothesis-generating findings offer transdiagnostic symptom factors that are differentially associated with neural function and could guide us toward a brain-based classification of psychiatric dysfunction in AUD. Results warrant further investigation of transdiagnostic approaches in addiction.

Perimenopausal Physical Activity and Dementia Risk: A Systematic Review

Mixed-gender studies predominate in the current literature exploring the interaction between physical activity and dementia risk. Considering that menopause appears to contribute to females' increased risk of cognitive decline when compared to males, further clarity is required on the impact of physical activity in reducing late-life dementia risk, specifically in perimenopausal females. A literature search of MEDLINE, EMBASE, Web of Science, SCOPUS and CINAHL databases yielded fourteen studies for review. A significant inverse relationship between perimenopausal leisure time physical activity, or physical fitness, and future all-cause dementia risk was found in most studies exploring this interaction. Higher levels of perimenopausal household physical activity and combined non-leisure time physical activity also displayed a favorable impact in lowering dementia risk. A dose-response effect was demonstrated, with approximately 10 MET-hour/week of leisure time physical activity required for significant dementia risk reduction. Three of four papers exploring causality provided analyses proposed to counter the reverse causation argument, suggesting that physical activity may indeed have a protective role in reducing dementia risk post-menopause. The current systematic review provides promising results regarding the impact of pre- and perimenopausal physical activity on reducing late-life dementia risk, suggesting that promoting perimenopausal physical activity may serve as a crucial tool in mitigating the risk of post-menopausal cognitive decline.

Astrocyte modulation in cerebral ischemia-reperfusion injury: A promising therapeutic strategy

Cerebral ischemia-reperfusion injury (CIRI) poses significant challenges for drug development due to its complex pathogenesis. Astrocyte involvement in CIRI pathogenesis has led to the development of novel astrocyte-targeting drug strategies. To comprehensively review the current literature, we conducted a thorough analysis from January 2012 to December 2023, identifying 82 drugs aimed at preventing and treating CIRI. These drugs target astrocytes to exert potential benefits in CIRI, and their primary actions include modulation of relevant signaling pathways to inhibit neuroinflammation and oxidative stress, reduce cerebral edema, restore blood-brain barrier integrity, suppress excitotoxicity, and regulate autophagy. Notably, active components from traditional Chinese medicines (TCM) such as Salvia miltiorrhiza, Ginkgo, and Ginseng exhibit these important pharmacological properties and show promise in the treatment of CIRI. This review highlights the potential of astrocyte-targeted drugs to ameliorate CIRI and categorizes them based on their mechanisms of action, underscoring their therapeutic potential in targeting astrocytes.

Multidisciplinary lifestyle interventions for neurological disorders during the Silent phase (MINDS) study: a multi-omics randomized controlled trial protocol

INTRODUCTION

Given the prevalence and staggering cost of neurological disorders, there is dire need for effective early detection and intervention tools. Emerging evidence suggests that multidisciplinary lifestyle interventions (MLI) may mitigate the risk and progression of neurological disorders. The objectives of this protocol are (1) to test the impact of MLI on the progression of neurological disorders and (2) to identify multi-omic biomarkers for early stages of neurological disease and the impact of MLIs on these biomarkers.

METHODS AND ANALYSIS

We present the Multidisciplinary lifestyle Interventions for Neurological Disorders during the Silent phase (MINDS) protocol, a randomized controlled trial of MLI in neurologically healthy older adults (≥ 50 years old) exhibiting elevated risk for common neurological disorders: stroke, epilepsy, Parkinson's Disease, or Alzheimer's disease and related dementias. Participants will be randomly assigned to intervention (n = 100) or control (n = 100) groups. The intervention group will receive 3 months of weekly 2-hour sessions on diet education, yoga, music therapy, and cognitive skills training. The participants' neurological health and engagement in relevant lifestyle practices will be assessed at regular intervals for 12 months. Neuroimaging and samples for multi-omic analyses will be collected at baseline, and at 3 months and 12 months after enrollment. Primary outcomes will be signs of progression of the neurological disorder risk that qualified them for study enrollment or a clinical diagnosis of the disorder. Secondary and exploratory outcomes will be based on self-reported health and multi-omic data. Data analysis will include between-group and longitudinal within-group analyses.

PERSPECTIVES

The MINDS protocol and trial aims to clarify the impact of MLI on the progression of neurological disorder risk or diagnosis in older adults and to identify biomarkers that can be used to confirm MLI efficacy. The ability to validate the impact of MLI on neurological disorder progression based on biomarker data allows the identification of individuals most likely to benefit from such therapies in the early stages of neurological disease.

TRIAL REGISTRATION

The trial is registered on the National Institutes of Health (NIH) ClinicalTrials.gov (NCT05984056) site. It was registered on August 2nd, 2023. The trial has full approval of the Cleveland Clinic Internal Review Board.

Cognitive-adaptive Functioning Gap and Mediating Factors that Impact Adaptive Functioning in Chinese Preschool-aged Children with Autism Spectrum Disorder

This study aimed to investigate the gap between adaptive functioning and cognitive functioning, especially verbal and nonverbal intelligence quotient (IQ) in Chinese children with ASD. We systematically explored cognitive functioning, ASD severity, early signs of developmental abnormalities, and socioeconomic factors as mediating factors of adaptive functioning. We enrolled 151 children (age: 2.5?6 years) with ASD and categorized them into one group with IQ ≥ 70 and another with IQ < 70. The two groups were calibrated for age, age at diagnosis, and IQ, and the relationship of adaptive skills with vocabulary acquisition index (VAI) and nonverbal index (NVI) were separately analyzed. Results show that the gap between IQ and adaptive functioning was significant in children with ASD having IQ ≥ 70, with both VAI and NVI showing statistically significant differences (all P < 0.001). VAI correlated positively with scores for overall adaptive skills and specific domains, whereas NVI had no significant correlations with adaptive skill scores. Age of first walking unaided had an independent positive correlation (all P < 0.05) with scores of adaptive skills and specific domains. IQ-adaptive functioning gap is significant in children with ASD having IQ ≥ 70, suggesting that defining "high-functioning autism" merely on the basis of IQ is not appropriate. Verbal IQ and early signs of motor development are specific and possible predictors of adaptive functioning in children with ASD, respectively.

Caregivers of individuals with borderline personality disorder: The relationship between leading caregiver interventions and psychological distress/positive mental well-being

Burden and psychological distress are higher in informal caregivers (ICs) of people with severe emotional and behavior dysregulation who have been given a diagnosis of borderline personality disorder (BPD) compared with non-caregivers. The current cross-sectional study examines the difference in outcomes of ICs of people with BPD who have received the intervention Family Connections (FC) and who also led interventions for other caregivers (caregiver-leaders) compared with those who have attended FC but not led caregiver interventions (non-leader-FC participants). The sample for this research is from a larger study (Hayes et al., 2023, Borderline Personality Disorder and Emotion Dysregulation, 10, 31). Data for 347 participants who self-reported receiving FC and completed the McLean Screening Instrument for BPD-Carer Version, the Brief COPE, the Multidimensional Scale of Perceived Social Support, the Kessler Psychological Distress scale, the WHO-5 Well-being Index, and the Coronavirus Anxiety Scale were analyzed. The results found that being a caregiver-leader was associated with higher positive mental well-being and lower psychological distress compared with non-leader-FC participants. Being a caregiver-leader was also associated with significantly greater use of the coping strategy of positive reframing and lower use of behavioral disengagement and self-blame than non-leader-FC participants. The study provides preliminary evidence that for those who have received FC, becoming an intervention leader is associated with better outcomes than caregivers who do not become leaders and provides support for caregiver-led rollout of FC across services.

Factors Influencing Caregivers' Use of Respite Care Services: Secondary Analysis of the National Study of Caregiving

This study examines when and why unpaid caregivers use respite services. We conducted a secondary analysis of the 2017 National Study of Caregiving (NSOC) Wave III, a U.S. nationally representative sample comprising 2652 unpaid caregivers. We found that unpaid caregivers reporting financial, physical, and emotional difficulties in caregiving were more likely to use respite care services than those not reporting these challenges. White, non-Hispanic caregivers reporting that they received support from their social networks (families/friends) were more likely to use respite care services than non-White and/or Hispanic caregivers receiving such support. Non-White and/or Hispanic caregivers who belonged to or attended support groups were more likely to use respite care support than those without social group affiliation. Respite care is underutilized in the U.S. despite its value and efficacy in supporting caregivers' mental and physical well-being. Policies are necessary to increase availability and access to respite services for diverse unpaid caregivers.

Exploring the parity paradox: Differential effects on neuroplasticity and inflammation by APOEe4 genotype at middle age

Female sex and Apolipoprotein E (APOE) ε4 genotype are top non-modifiable risk factors for Alzheimer's disease (AD). Although female-unique experiences like parity (pregnancy and motherhood) have positive effects on neuroplasticity at middle age, previous pregnancy may also contribute to AD risk. To explore these seemingly paradoxical long-term effects of parity, we investigated the impact of parity with APOEε4 genotype by examining behavioural and neural biomarkers of brain health in middle-aged female rats. Our findings show that primiparous (parous one time) hAPOEε4 rats display increased use of a non-spatial cognitive strategy and exhibit decreased number and recruitment of new-born neurons in the ventral dentate gyrus of the hippocampus in response to spatial working memory retrieval. Furthermore, primiparity and hAPOEε4 genotype synergistically modulate inflammatory markers in the ventral hippocampus. Collectively, these findings demonstrate that previous parity in hAPOEε4 rats confers an added risk to present with reduced activity and engagement of the hippocampus as well as elevated pro-inflammatory signaling, and underscore the importance of considering female-specific factors and genotype in health research.

"It was a reflection of myself, that i was weak": The impact of depression on the sense of self - An interpretive phenomenological analysis

The World Health Organisation states that more than 350 million people experience depression globally. The phenomenological changes in individuals experiencing depression are profound Phenomenological research can further researchers' and clinicians' understanding of this experience. This study aimed to gain a phenomenological understanding of how individuals with depression understood and made sense of their experiences. A methodology of interpretative phenomenological analysis was adopted. In-depth semi-structured interviews explored the lived experience of depression for eight individuals. Data were analysed into the superordinate theme Broken Self - Transforming the Self. The superordinate theme developed from the subordinate themes of 'unknown self, loss of self and one's identity', 'desperate for a way out', and thirdly, 'conflict with self and what's known', which related directly to how individuals made sense of their experience of depression. These research findings highlight the human implications of the experience of depression and the limitations of viewing depression from a biological or medical model lens. Understanding the human impact is essential for the effective, holistic practice of mental health nursing.

The Relationship Between Poststroke Dysphagia and Poststroke Depression and Its Risk Factors

PURPOSE

A diagnosis of dysphagia and/or depression after stroke can impact the physical, psychological, and social welfare of stroke survivors. Although poststroke depression (PSD) and poststroke dysphagia are known to occur concurrently, there is a paucity of research that has specifically investigated their association. Therefore, we aimed to study the relationship between PSD and poststroke dysphagia during acute inpatient hospitalization and within 90 days after discharge. Furthermore, we aimed to evaluate the odds and hazard of being diagnosed with depression after stroke and estimate the time to depression diagnosis from the initial stroke diagnosis in patients with and without a diagnosis of dysphagia.

METHOD

Using the acute inpatient hospital data set from our previous work, we pulled additional postdischarge administrative claims data from the 2017 Medicare 5% Limited Data Set and conducted a retrospective, cross-sectional study of patients diagnosed with poststroke dysphagia and PSD.

RESULTS

Patients diagnosed with poststroke dysphagia had 2.7 higher odds of being diagnosed with PSD and had an approximately 1.75-fold higher hazard for PSD diagnosis in the 90 days after discharge compared to patients not diagnosed with dysphagia. Risk factors for PSD included having dysphagia, being female, and having dual eligibility.

CONCLUSIONS

Our results demonstrated a significant association between PSD and poststroke dysphagia. Additional research should further explore the impact of PSD on poststroke dysphagia.

The effect of cognitive reappraisal on emotion recognition in mothers of children with special needs

Intrinsic family dynamics are an important factor in the development of children with special needs, and mothers' emotion regulation ability influences children's development to some extent. This study examined the intrinsic mechanism of cognitive reappraisal of emotion regulation strategies affecting the emotion recognition ability of mothers of children with special needs. Results indicated that mothers of children with special needs recognized negative emotions significantly faster than typically developing child mothers. After receiving cognitive reappraisal emotion regulation strategies, they significantly improved emotional recognition of surprise and reduced attention bias towards anger. Overall, mothers of children with special needs may have obvious attention bias towards negative emotions, and cognitive reappraisal can target negative emotions to help them to better improve emotional resilience.

Development of a nomogram for predicting acute pain among patients after abdominal surgery: A prospective observational study

AIMS

To develop a nomogram to provide a screening tool for recognising patients at risk of post-operative pain undergoing abdominal operations.

BACKGROUND

Risk prediction models for acute post-operative pain can allow initiating prevention strategies, which are valuable for post-operative pain management and recovery. Despite the increasing number of studies on risk factors, there were inconsistent findings across different studies. In addition, few studies have comprehensively explored predictors of post-operative acute pain and built prediction models.

DESIGN

A prospective observational study.

METHODS

A total of 352 patients undergoing abdominal operations from June 2022 to December 2022 participated in this investigation. A nomogram was developed for predicting the probability of acute pain after abdominal surgery according to the results of binary logistic regression. The nomogram's predictive performance was assessed by discrimination and calibration. Internal validation was performed via Bootstrap with 1000 re-samplings.

RESULTS

A total of 139 patients experienced acute post-operative pain following abdominal surgery, with an incidence of 39.49%. Age <60, marital status (unmarried, divorced, or widowed), consumption of intraoperative remifentanil >2 mg, indwelling of drainage tubes, poor quality sleep, high pain catastrophizing, low pain self-efficacy, and PCIA not used were predictors of inadequate pain control in patients after abdominal surgery. Using these variables, we developed a nomogram model. All tested indicators showed that the model has reliable discrimination and calibration.

CONCLUSIONS

This study established an online dynamic predictive model that can offer an individualised risk assessment of acute pain after abdominal surgery. Our model had good differentiation and calibration and was verified internally as a useful tool for risk assessment.

RELEVANCE TO CLINICAL PRACTICE

The constructed nomogram model could be a practical tool for predicting the risk of experiencing acute post-operative pain in patients undergoing abdominal operations, which would be helpful to realise personalised management and prevention strategies for post-operative pain.

REPORTING METHOD

The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were adopted in this study.

PATIENT OR PUBLIC CONTRIBUTION

Before the surgery, research group members visited the patients who met the inclusion criteria and explained the purpose and scope of the study to them. After informed consent, they completed the questionnaire. The patients' pain scores (VAS) were regularly assessed and documented by the bedside nurse for the first 3 days following surgery. Other information was obtained from medical records.

Protein modification in neurodegenerative diseases

Posttranslational modifications play a crucial role in governing cellular functions and protein behavior. Researchers have implicated dysregulated posttranslational modifications in protein misfolding, which results in cytotoxicity, particularly in neurodegenerative diseases such as Alzheimer disease, Parkinson disease, and Huntington disease. These aberrant posttranslational modifications cause proteins to gather in certain parts of the brain that are linked to the development of the diseases. This leads to neuronal dysfunction and the start of neurodegenerative disease symptoms. Cognitive decline and neurological impairments commonly manifest in neurodegenerative disease patients, underscoring the urgency of comprehending the posttranslational modifications' impact on protein function for targeted therapeutic interventions. This review elucidates the critical link between neurodegenerative diseases and specific posttranslational modifications, focusing on Tau, APP, α-synuclein, Huntingtin protein, Parkin, DJ-1, and Drp1. By delineating the prominent aberrant posttranslational modifications within Alzheimer disease, Parkinson disease, and Huntington disease, the review underscores the significance of understanding the interplay among these modifications. Emphasizing 10 key abnormal posttranslational modifications, this study aims to provide a comprehensive framework for investigating neurodegenerative diseases holistically. The insights presented herein shed light on potential therapeutic avenues aimed at modulating posttranslational modifications to mitigate protein aggregation and retard neurodegenerative disease progression.

Tango classes in people with Multiple Sclerosis (PwMS): Impact on motor and non-motor functions

BACKGROUND

While music-based therapy (MBT) has been shown to improve motor and non-motor features in multiple sclerosis (MS), benefits of tango have never been assessed.

OBJECTIVE

To evaluate the benefits of tango classes on quality of life (QoL), mood, fatigue, gait, balance, perception of cognitive disorder and sexuality in people with MS.

METHODS

7 participants (age 41.14 ± 14.27 years, disease duration 14.14 ± 7.6 years) and respective partners undertook one-hour weekly classes for 20 weeks. Participants had early-stage MS (EDSS<3.5). They were assessed for mood (ZUNG rating scale; Beck Depression Inventory -II); balance (Berg Balance Test; Tinetti scale), cognition (MS Neuropsychological Screening Questionnaire), SD (Multiple Sclerosis Intimacy and Sexuality Questionnaire), fatigue (Fatigue Severity Scale) and QoL (36-Item Short Form Survey).

RESULTS

Group comparison of pre-post change scores showed a general improvement in all the outcome measures, which was significant in mood, SD, cognition and QoL.

DISCUSSIONS AND CONCLUSION

Tango classes provides benefits to pwMS, especially on non-motor symptoms. Follow-up assessment is required to confirm the durability of these effects.

Honokiol relieves hippocampal neuronal damage in Alzheimer's disease by activating the SIRT3-mediated mitochondrial autophagy

BACKGROUND

This work elucidated the effect of honokiol (HKL) on hippocampal neuronal mitochondrial function in Alzheimer's disease (AD).

METHODS

APP/PS1 mice were used as AD mice models and exposed to HKL and 3-TYP. Morris water maze experiment was performed to appraise cognitive performance of mice. Hippocampal Aβ+ plaque deposition and neuronal survival was evaluated by immunohistochemistry and Nissl staining. Hippocampal neurons were dissociated from C57BL/6 mouse embryos. Hippocampal neuronal AD model was constructed by Aβ oligomers induction and treated with HKL, CsA and 3-TYP. Neuronal viability and apoptosis were detected by cell counting kit-8 assay and TUNEL staining. mRFP-eGFP-LC3 assay, MitoSOX Red, dichlorodihydrofluorescein diacetate, and JC-1 staining were performed to monitor neuronal autophagosomes, mitochondrial reactive oxygen species (ROS), neuronal ROS, and mitochondrial membrane potential. Autophagy-related proteins were detected by Western blot.

RESULTS

In AD mice, HKL improved cognitive function, relieved hippocampal Aβ1-42 plaque deposition, promoted hippocampal neuron survival, and activated hippocampal SIRT3 expression and mitochondrial autophagy. These effects of HKL on AD mice were abolished by 3-TYP treatment. In hippocampal neuronal AD model, HKL increased neuronal activity, attenuated neuronal apoptosis and Aβ aggregation, activated SIRT3 and mitochondrial autophagy, reduced mitochondrial and neuronal ROS, and elevated mitochondrial membrane potential. CsA treatment and 3-TYP treatment abrogated the protection of HKL on hippocampal neuronal AD model. The promotion of mitochondrial autophagy by HKL in hippocampal neuronal AD model was counteracted by 3-TYP.

CONCLUSIONS

HKL activates SIRT3-mediated mitochondrial autophagy to mitigate hippocampal neuronal damage in AD. HKL may be effective in treating AD.

The myth of brain damage: no change of neurofilament light chain during transient cognitive side-effects of ECT

Electroconvulsive therapy (ECT) is an effective, safe, and mostly well-tolerated treatment for patients with severe or difficult to treat depression or psychotic disorders. However, a relevant number of patients experience subjective and/or objective cognitive side-effects. The mechanism of these transient deficits is not yet clear. Thus, our study prospectively investigated neurofilament light chain (NfL) concentrations as a highly sensitive biomarker for neuroaxonal damage along with cognitive performance during a course of ECT. Serum NfL concentrations from 15 patients with major depressive disorder receiving ECT were analyzed (1) 24 h before the first ECT, (2) 24 h and (3) 7 days after the last ECT (45 measurements in total). Neuropsychological testing including memory, executive functions and attention was performed at each time-point. NfL concentrations did not change between the three time-points, while a temporary cognitive impairment was found. Even in the subset of patients with the strongest impairment, NfL concentrations remained unchanged. Neuropsychological testing revealed the common pattern of transient cognitive side-effects with reduced performance 24 h post-ECT (global cognition score: p < 0.001; memory: p = 0.043; executive functions: p = 0.002) and return to baseline after 7 days (all p < 0.001). Our study adds to the evidence that neither ECT per se nor the transient cognitive side-effects seem to be associated with an increase of NfL as a marker of neuroaxonal damage. In contrast, we discuss cognitive side effects to be potentially interpreted as a byproduct of ECT's neuroplastic effects.

Associations among early life adversity, sleep disturbances, and depressive symptoms in adolescent females and males: a longitudinal investigation

BACKGROUND

Exposure to adversity early in life (ELA) has been associated with elevated risk for depression during adolescence, particularly for females; the mechanisms underlying this association, however, are poorly understood. One potential mechanism linking ELA and sex differences in depressive symptoms is sleep disturbances, which increase during adolescence and are more common in females. Here, we examined whether sleep disturbances mediate the association between ELA and increases in depressive symptoms during adolescence and whether this mediation differs by sex.

METHODS

224 (N = 132 females) youth were recruited at age 9-13 years and assessed every 2 years across three timepoints. At the first timepoint, we conducted extensive interviews about stressful events participants experienced; participants provided subjective severity ratings of events and we objectively scored the severity of each event. Self-reported sleep disturbances and depressive symptoms were assessed at all timepoints. We conducted linear mixed models to estimate both initial levels and changes in sleep disturbances and depressive symptoms, and moderated mediation analyses to test whether initial levels and/or changes in sleep disturbances mediated the association of ELA (objective and subjective) with increases in depressive symptoms across adolescence and whether the mediations differed by sex.

RESULTS

While higher initial levels and increases in sleep problems were uniquely associated with increases in depressive symptoms for males and females, they were related to ELA differently by sex. For females, greater ELA (both objectively and subjectively rated) was associated with higher initial levels of sleep problems, which in turn were associated with increases in depressive symptoms from early to late adolescence. In contrast, for males, ELA exposure was not associated with either initial levels of, or increases in, sleep problems.

CONCLUSIONS

These findings highlight the role of sleep disturbances during the transition to adolescence in mediating sex differences in the effects of ELA on depressive symptoms.

Precision Medicine in Parkinson's Disease Using Induced Pluripotent Stem Cells

Parkinson's disease (PD) is one of the most devastating neurological diseases; however, there is no effective cure yet. The availability of human induced pluripotent stem cells (iPSCs) provides unprecedented opportunities to understand the pathogenic mechanism and identification of new therapy for PD. Here a new model system of PD, including 2D human iPSC-derived midbrain dopaminergic (mDA) neurons, 3D iPSC-derived midbrain organoids (MOs) with cellular complexity, and more advanced microphysiological systems (MPS) with 3D organoids, is introduced. It is believed that successful integrations and applications of iPSC, organoid, and MPS technologies can bring new insight on PD's pathogenesis that will lead to more effective treatments for this debilitating disease.

'On the slope of an erupting volcano': A qualitative study on the workplace violence experiences of psychiatric nurses

WHAT IS KNOWN ON THE SUBJECT?: Workplace violence is common in healthcare. Workplace violence remains a complex and serious occupational hazard in healthcare. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Since there is no study examining detailed explanations of experiences and perspectives of workplace violence among psychiatric nurses, this study will act as a guide for psychiatric nurses. This study provides information about how psychiatric nurses evaluate the concept of workplace violence from their perspective, what it means to them and the effects of workplace violence. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Considering the effects of workplace violence, a preventive, systematic and holistic approach should be used in psychiatry and community mental health centres. Supportive interventions should be used to improve the health and safety of psychiatric nurses and patients.

ABSTRACT

INTRODUCTION: Workplace violence is common in healthcare and remains a complex and serious occupational hazard.

AIM

This research was conducted to assess the workplace violence experiences and perspectives of psychiatric nurses.

METHOD

This study was a qualitative study conducted using a grounded theory approach method. The study was conducted between November 2022 and January 2023. The purposeful sampling method was used, and 11 psychiatric nurses were interviewed. Data were collected with an information form and a semi-structured interview form. The data were analysed using content analysis, and themes were created.

FINDINGS

The ages of the psychiatric nurses ranged from 38 to 57 years. Themes and sub-themes related to the workplace violence experiences and perspectives of psychiatric nurses included the way of violence (rising tension, eruption of the volcano, unintentional violence and turning to ash) and empowerment (ash cloud and ring of fire).

CONCLUSION

Psychiatric nurses stated that they were exposed to verbal and physical violence for many reasons, that this situation seriously affected their physical, mental and social health and that in addition to the devastating effects of violence, they became stronger by developing various skills to protect against violence.

IMPLICATIONS FOR PRACTICE

Supportive interventions should be used to improve the health and safety of psychiatric nurses and patients. Strategies can be developed to include psychiatric nurses in occupational health nursing courses.

Predicting postoperative delirium assessed by the Nursing Screening Delirium Scale in the recovery room for non-cardiac surgeries without craniotomy: A retrospective study using a machine learning approach

Postoperative delirium (POD) contributes to severe outcomes such as death or development of dementia. Thus, it is desirable to identify vulnerable patients in advance during the perioperative phase. Previous studies mainly investigated risk factors for delirium during hospitalization and further used a linear logistic regression (LR) approach with time-invariant data. Studies have not investigated patients' fluctuating conditions to support POD precautions. In this single-center study, we aimed to predict POD in a recovery room setting with a non-linear machine learning (ML) technique using pre-, intra-, and postoperative data. The target variable POD was defined with the Nursing Screening Delirium Scale (Nu-DESC) ≥ 1. Feature selection was conducted based on robust univariate test statistics and L1 regularization. Non-linear multi-layer perceptron (MLP) as well as tree-based models were trained and evaluated-with the receiver operating characteristics curve (AUROC), the area under precision recall curve (AUPRC), and additional metrics-against LR and published models on bootstrapped testing data. The prevalence of POD was 8.2% in a sample of 73,181 surgeries performed between 2017 and 2020. Significant univariate impact factors were the preoperative ASA status (American Society of Anesthesiologists physical status classification system), the intraoperative amount of given remifentanil, and the postoperative Aldrete score. The best model used pre-, intra-, and postoperative data. The non-linear boosted trees model achieved a mean AUROC of 0.854 and a mean AUPRC of 0.418 outperforming linear LR, well as best applied and retrained baseline models. Overall, non-linear machine learning models using data from multiple perioperative time phases were superior to traditional ones in predicting POD in the recovery room. Class imbalance was seen as a main impediment for model application in clinical practice.

Nurses' knowledge and beliefs on pain management practices with hospitalised persons living with dementia: A qualitative descriptive study

AIM

To understand nurses' knowledge, beliefs and experiences affect pain management practices in hospitalised persons living with dementia (PLWD).

DESIGN

Naturalistic inquiry using qualitative descriptive design.

METHODS

Semi-structured interviews were conducted with 12 registered nurses who worked in one acute care hospital in Southern California from October to November 2022. Data were analysed using content analysis to identify themes.

RESULTS

Two themes were developed: improvising pain assessment, which included how pain was documented, and administration hesitancy referring to nurse's concerns about PLWD's confusion. Nurses described the challenges of assessing pain in hospitalised PLWD particularly if they were non-verbal and/or demonstrating responsive behaviours. Nurse's years of experience, dementia stigma, and their unconscious biases affected nurses' pain management practices.

CONCLUSIONS

The study findings highlight the complex challenges of pain management in hospitalised PLWD that are exacerbated by nurses' knowledge deficits, negative stereotypical beliefs, dementia stigma and unconscious biases towards older people that contributes to undermanaged pain in hospitalised PLWD.

IMPLICATIONS

A comprehensive strategy using an implementation framework is needed to address nurse's knowledge gaps, unconscious bias, dementia stigma and techniques that enhance communication skills is suggested. Building a foundation in these areas would improve pain management in hospitalised PLWD.

IMPACT

Improving pain management in hospitalised PLWD would improve the quality of life, decrease hospital length of stay, prevent readmissions, and improve nurse satisfaction.

REPORTING METHOD

The study adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ).

PATIENT CONTRIBUTIONS

Improving pain management in hospitalised PLWD would prevent long term confusion, episodes of delirium and improve quality of life as they recover from their acute illness for which they required hospital care.

Optimally combining transcranial magnetic stimulation with antidepressants in major depressive disorder: A systematic review and Meta-analysis

There is a critical knowledge gap in optimally combining transcranial magnetic stimulation (TMS) and antidepressants to treat patients with major depressive disorder (MDD). TMS is effective in treating MDD in patients who have failed at least one antidepressant trial, with accelerated protocols showing faster remission in treatment-resistant depression (TRD). Although clinicians routinely augment antidepressants with TMS, there is a knowledge gap in stopping versus continuing antidepressants or the dosing strategies when starting or tapering TMS. These considerations are important when considering maintenance TMS (delivered alone or in combination with suitable antidepressants) to maintain remission in MDD after the index course of TMS. As the first step towards filling this knowledge gap, we reviewed randomized controlled trials (RCTs) and open-label trials from 2 databases (PubMed/Medline and EMBASE) that compared active TMS combined with a pre-specified antidepressant dosed in the same manner for adults with MDD versus sham TMS combined with the same antidepressant as in the active arm. All studies were published between January 1, 2000, and December 31, 2023. We excluded case reports, case series, and clinical studies that augmented TMS with antidepressants and vice versa. We found 10 RCTs (n = 654 participants) and performed a meta-analysis. This showed active TMS combined with pre-specified antidepressants had greater efficacy for MDD treatment than sham TMS combined with the same antidepressants as in the active arm (Hedge's g = 1; 95 % CI [0.27, 1.73]). The review and meta-analysis indicate greater short-term efficacy in combining antidepressants with TMS from the get-go in MDD. Given the increasing role of accelerated TMS protocols in expediting remission in MDD and the results of our meta-analysis, we advocate for RCTs examining the short-term and long-term effects of various antidepressant classes on these TMS protocols in MDD. This can also optimize and individualize maintenance TMS protocols to prevent relapse in MDD.

Usability of web-based tools designed for communication and decision-making in dementia: Systematic review and design brief

INTRODUCTION

There is an increased number of web-based tools designed for people with dementia and their family caregivers and addressing communication and decision-making. The loss of cognitive functions associated with dementia can impact individuals' experiences and use of web-based tools. There is a need for high quality and user-friendly web-based tools that support communication and decision-making for people with dementia and their family caregivers.

OBJECTIVE

To identify usability requirements, usability testing methods, and design suggestions from studies focusing on web-based tools for communication and decision-making support in dementia care.

METHODS

We conducted a systematic review with narrative synthesis. Five databases were systematically searched in February 2023. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool.

RESULTS

A total of 1,032 articles were identified and 7 fulfilled inclusion criteria. Web-based tools addressed technology usage, health promotion, home modification information, shared decision-making facilitation, information needs and social isolation. Methods to test usability included surveys, interviews, focus groups, cognitive walkthroughs and think-aloud procedures. Findings suggested reducing cognitive load, enhancing readability, providing clear language, and emphasising the need for additional support for people with dementia. Design recommendations include optimising information delivery and presentation, enhancing visual elements, streamlining navigation, providing concrete examples, using clear language, and offering training and tailored support.

CONCLUSION

Usability requirements ranged from visual appearance and navigation to delivery of content and support needed. This review contributes to efforts to improve design and development of web-based tools targeting communication and decision-making in dementia care. Further research should address tailored support to enhance usability for people with dementia.

Adherence to exercise in lateral elbow tendinopathy, a scoping review

BACKGROUND

Understanding the true effects of exercise in the treatment of lateral elbow tendinopathy (LET) is hampered by insufficient information or a lack of standardisation in defining, measuring, reporting and analysis of exercise adherence.

OBJECTIVES

This scoping review aimed to explore both the quantity and scope of reporting of exercise adherence in published studies of participants with LET.

METHOD

Six databases were searched to identify original research studies written in English, investigating therapeutic exercise for LET. Eligible studies were first searched for terms related to exercise adherence. If provided, information on the terminology, definition, measurement, results and analysis of adherence were collated and summarised. Recommendations for standardized reporting of exercise adherence were developed.

RESULTS

104 studies were identified, of which 74 (71%) did not report adherence or related terms. Reference to exercise compliance or adherence occurred in 17 and 13 studies respectively. Adherence was most commonly defined as the frequency or percentage of exercise sessions completed compared to the recommendation and measured by self-reported diary. Few studies defined a threshold for adherence, provided comprehensive reporting of results or analysis of exercise adherence.

CONCLUSION

Reporting of exercise adherence in studies of LET was limited in both quantity and scope. Recommendations are made to improve the quality and consistency of reporting in future studies.

Development of a Standardized Suicide Prevention Program for Gatekeeper Intervention in Korea (Suicide CARE Version 2.0) to Prevent Adolescent Suicide: Version for Teachers

OBJECTIVE

The increasing concern over adolescent suicide necessitates suicide prevention training for school teachers, as students spend a significant portion of their time at school. This study's objective is to develop a suicide prevention program tailored for teachers.

METHODS

The program was developed by a multidisciplinary research team, drawing on a review of both domestic and international suicide prevention programs, related scholarly articles, and Korean psychological autopsy interviews of adolescents. This was complemented by a survey of teachers to assess the program's practicality and usability.

RESULTS

The developed program comprises three parts, consistent with other versions: Careful Observation, Active Listening, and Risk Evaluation and Expert Referral. Careful Observation focuses on training teachers to recognize verbal, behavioral, and situational warning signs of suicidal ideation in students; Active Listening involves strategies for encouraging students to express their suicidal thoughts and techniques for being an empathetic and attentive listener; Risk Evaluation and Expert Referral provides instruction on how to assess suicide risk and assist students safely.

CONCLUSION

It is anticipated that this program will equip teachers with valuable knowledge and skills, contributing to a reduction in adolescents suicide rates.
