Unraveling the relationships among pandemic fear, cyberchondria, and alexithymia after China's exit from the zero-COVID policy: insights from a multi-center network analysis
Li Y, Li J, Zhou C, Huang C, Luo B, Hu Y, Huang X and Fang J
China's abrupt exit from the zero-COVID policy in late 2022 led to a rapid surge in infections, overwhelming healthcare systems and exposing healthcare providers to intensified psychological pressures. This sudden shift exacerbated pandemic-related psychological issues, including fear, health anxiety, and emotional processing difficulties. This study aimed to unravel the relationships among pandemic fear, cyberchondria, and alexithymia following China's exit from the zero-COVID policy.

Tao S, Yu L, Li J, Wu J, Yang D, Huang X and Xue T
Remnant cholesterol (RC) has received increasing attention due to its association with a variety of diseases. However, comprehensive population-based studies elucidating the relationship between RC and major depressive disorder (MDD) are limited. The current study aimed to determine the association between RC and MDD in US adults.
Association between omega-3 index and depersonalization among healthcare workers in a university hospital: a cross-sectional study
Antao HS, Sacadura-Leite E, Aguiar P, Gois C, Marques J, Pombo S and Figueira ML
Burnout harms workers physical and mental health due to induced brain changes, autonomous nervous system and hypothalamus-pituitary-adrenal axis excessive activation. Although several correlations and risk factors have been identified, the research around burnout biological correlates remains underdeveloped. The omega-3 index has been proposed in mental health as a contributor to identify high risk patients and monitor disease advancements but the evidence on its relationship with burnout is limited. This study is meant to test the hypothesis that the omega-3 index is inversely associated with burnout levels and to discuss its potential as a biological correlate of burnout.
The dopamine hypothesis for ADHD: An evaluation of evidence accumulated from human studies and animal models
MacDonald HJ, Kleppe R, Szigetvari PD and Haavik J
Multiple lines of evidence indicate that altered dopamine signaling may be involved in neuropsychiatric disorders and common behavioral traits. Here we critically review evidence collected during the past 40-plus years supporting the role of dopamine dysfunction in attention deficit hyperactivity disorder (ADHD). We recapitulate the basic components of dopaminergic signaling in the central nervous system, focusing on core enzymes, transporters and receptors involved in monoaminergic functions, particularly in striatal and cortical regions. We summarize key human brain imaging and genetic studies reporting associations between dopaminergic neurotransmission and behavioral traits, with an emphasis on ADHD. We also consider ADHD in the context of animal models and single gene, metabolic, and neurological disorders with established dysfunction of the dopaminergic system. Examining the evidence in this way leads us to conclude that there is evidence for the involvement of dopamine but limited evidence for a hypo-dopaminergic state as a key component of ADHD. We propose a path forward to increase our understanding of dopamine signaling in human behavioral traits and disorders that should particularly focus on its role in clinical subgroups, during brain development and how it interacts with other neurotransmitter systems.
Development of personalized profiles of students with autism spectrum disorder for interactive interventions with robots to enhance language and social skills
Herrero-Martín J, Fonseca D, Caro-Via S and Canaleta X
The inclusion of students with autism spectrum disorder (ASD) in mainstream education (primary and secondary, in the range of 4-5 to 8-10 years old) is a complex task that has long challenged both educators and health professionals. However, the correct use of digital technologies such as personalization settings and interaction with robots has clearly shown how these new technologies can benefit ASD students. However, it is essential to characterize the profile, problems, and needs of each student, since it is not possible to generalize an accessible approach for all users. The work presented shows the creation and validation, through pilot tests, of an instrument that outlines the main needs of a student with ASD, based on behavioral variables. In a later phase, instructional sequences will be designed and adapted through digital tablets and interaction with a robot to improve specific aspects identified in the initial profile. The results demonstrate the method's ability to assess and prioritize profiles satisfactorily which helps create a design adjusted to each student. The first pilot tests have been well received by ASD students, who have shown increased interest in the contents and methods used in this approach. Motivation levels and engagement have also increased, and social interactions with their peers have improved.
Unmasking the impact of COVID-19 on the mental health of college students: a cross-sectional study
Gandhi S, Jordan A, Glaman R and Morrow B
Safeguarding college students' mental health and well-being poses a challenge for college administrators and clinicians because of the unique circumstances students face and the limited literature on their needs. Prior to the pandemic, depression and anxiety were already on the rise among college students, but the changes associated with it may have exacerbated these issues. Our study aimed to explore factors influencing college students' mental health and identify common trends in their experiences that could assist organizations and policymakers in the future.
Change in self-construal: a repertory grid technique study of women admitted to a Mother and Baby Unit
Wozniak EE, Hare DJ, Gregg L and Wittkowski A
Pregnancy and the postnatal period represent a time of heightened risk for women to experience mental health difficulties. Some mothers may require specialist inpatient psychiatric support made available through Mother and Baby units (MBUs). Although there is evidence of the therapeutic benefits of MBUs, many studies have utilised methodologies vulnerable to interviewer and social desirability biases. The repertory grid technique (RGT), derived from personal construct theory (PCT), has been successfully used to explore how the way in which a person thinks about and defines the self (i.e., self-construal) changes following therapeutic intervention in samples of people experiencing mental health conditions. Therefore, this study aimed to explore change in maternal self-construal following MBU admission, utilising the RGT, thereby enhancing our understanding for the therapeutic role of MBU admissions in women's mental health recoveries.
Neurofilament light chain plasma levels in major depressive disorder: a brief research report
Fernández-Pereira C, Fernández-Ceballos MLÁ, Olivares JM, Prieto-González JM and Agís-Balboa RC
Peripheral neurofilament light chain (NfL) reflect neuronal and axonal damage. Most studies have been focused on NfL cerebrospinal fluid measures since peripheral levels were difficult to detect. However, with recent advent of single molecule array (SIMOA) technology, NfL is now detectable peripherally at small concentrations (pg/ml). In neurodegenerative disorders, NfL peripheral levels have been found significantly elevated compared against psychiatric disorders. However, there is still controversy of whether NfL peripheral levels might be altered in psychiatric disorders like major depressive disorder (MDD) when compared against a normal population.
Association between the American Heart Association's New Life's Essential 8 Metrics and Depression Symptom in U.S General Adults, Finding from NHANES 2005-2018
Ruan Z, Zhu J, Xu S, Liang J and Shi S
The American Heart Association (AHA) recently introduced a new metric for promoting cardiovascular health (CVH) called Life's Essential 8 (LE8). However, there has been no investigation into the relationship between levels of LE8 and the risk of depression symptom. Therefore, our objective was to determine this association using a nationally representative sample of U.S adults.

Methylphenidate abuse and misuse in patients affected with a psychiatric disorder and a substance use disorder: a systematic review
Chiappini S, Gramuglia PD, Mosca A, Cavallotto C, Miuli A, Corkery JM, Guirguis A, Schifano F and Martinotti G
Methylphenidate (MPH), a central nervous system stimulant primarily prescribed for attention-deficit/hyperactivity disorder (ADHD), has seen increasing rates of misuse and abuse, particularly in patients with dual diagnosis (co-occurring psychiatric disorders and substance use disorders/SUDs). The heightened risk of dependence and adverse effects in these vulnerable populations warrants a systematic review to assess the prevalence and pattern of abuse/misuse of MPH among patients within this population and to understand potential risk factors, patterns of misuse, and outcomes, including the impact on psychiatric symptoms and overall mental health, the effects on SUD (e.g., exacerbation or mitigation of symptoms), and the incidence of adverse events and complications (e.g., cardiovascular issues, psychological effects).
A multidisciplinary weight management intervention for adults with severe mental illness in forensic psychiatric inpatient services (Motiv8): a single blind cluster-randomised wait-list controlled feasibility trial
Carney R, Law H, El-Metaal H, Hann M, Shields G, Savage S, Small I, Jones R, Shiers D, Macafee G and Parker S
People with severe mental illness experience physical health inequalities and a 15-20-year premature mortality rate. Forensic inpatients are particularly affected by restrictions on movement, long admissions, and obesogenic/sedative psychotropic medication. We aimed to establish the feasibility and acceptability of Motiv8, a multidisciplinary weight management intervention co-produced with service users for forensic inpatients.
Multi-environment prediction of suicidal beliefs
Goddard AV, Su AY, Xiang Y and Bryan CJ
Suicide disproportionately affects the military and veteran population, yet the task of identifying those at an increased risk of suicidal behavior remains challenging. In the face of this complex issue, novel machine learning methods have been applied to study the relationship between suicide and potential risk factors, but are often not generalizable to new and unseen samples. Herein, we examine the problem of prediction on unknown environments, commonly known as environment-wise domain adaptation, as it relates to the prediction of suicidal beliefs, measured with items from the Suicide Cognitions Scale (SCS). We adapt several recently invariance-based models trained using a sample consisting of people without any prior suicidal ideation (SI) to the prediction of suicidal beliefs of those with prior SI. In addition, we examine the possible causal relations regarding the SCS. Using a prospective sample of 2744 primary care patients with 17 risk and protective factors, we show that, to some extent, these methods are able to generalize to a new environment, namely, a sample with prior SI. Additionally, our results indicate suicidal ideation and suicidal behavior are likely to be causal children of SCS.

Chang C, Piao Y, Zhang M, Liu Y, Du M, Yang M, Mei T, Wu C, Wang Y, Chen X, Zeng GQ and Zhang X
With the advancement of transcranial electrical stimulation (tES) technology, an increasing number of stimulation devices and treatment protocols have emerged. However, safety and tolerability remain critical concerns before new strategies can be implemented. Particularly, the use of gel particle electrodes brings new challenges to the safety and tolerability of tES, which hinders its widespread adoption and further research.
Exploring how children and adolescents talk about coping strategies relating to loneliness using reflexive thematic analysis: a qualitative study
Burke L, Verity L, Riddleston L, Fuhrmann D, Qualter P, Lau JYF and Demkowicz O
The prevailing view is that loneliness predominantly affects older adults. However, awareness of high rates of loneliness among younger populations is growing, prompting a call for interventions. The current study aimed to listen to the voices of young people regarding how they cope with loneliness, gaining a better understanding of how to then develop tailored interventions.
Chasing among older-aged gamblers: the role of mentalizing and psychological distress
Ciccarelli M, Pizzini B, Cosenza M, D'Olimpio F, Griffiths MD and Nigro G
Despite the increasing proportion of older-aged individuals suffering from problematic gambling, research on gambling among this specific age cohort is still in its infancy. Chasing is a pathognomonic feature of disordered gambling and is considered one of the key risk factors in the transition from recreational to disordered gambling. Despite the increased research on chasing over the past decade, no previous study has ever examined the psychological determinants of chasing behavior among old-aged gamblers. Given the importance of chasing in facilitating and maintaining problem gambling, and the paucity of research examining gambling among older individuals, the present study is the first to empirically investigate the joint role of chasing behavior, negative affectivity, and mentalizing among older-aged gamblers.
