Nicotinamide Riboside Attenuates Memory Impairment and Depressive-like Behavior in an Alzheimer’s Disease Animal Model
Authors: Aytulun A. , Cimen B. , Sara Y. , Erden Aki S. Ö.
Published: August 2024

Introduction

Depression in Alzheimer’s disease (AD) differs from major depression in terms of clinical features and treatment. Antidepressants do not provide the expected benefits in depressive symptoms accompanying cognitive decline in AD, suggesting distinct mechanisms. Emerging research suggest that compromised mitophagy, the selective removal of damaged mitochondria, may contribute to the pathogenesis of AD. However boosting nicotinamide adenine dinucleotide (NAD+) to induce mitophagy reduces amyloid β (Aβ) aggregation and enhances cognitive function in AD models (Kerr
et al.,Trends Neurosci 2017;40:151-66). Nevertheless, data on NAD’s impact on depression in AD remains limited.

Objectives

This study aimed to examine the impact of the NAD+ precursor nicotinamide riboside (NR) on cognitive and neuropsychiatric symptoms in a AD rat model.

Methods

To induce the AD, a single dose of 5 μl Aβ1-42 was injected into each lateral ventricle of rats (day 0), while the control group received an intracerebroventricular (icv) saline (0.9%NaCl).Four experimental groups were designed: control (icv saline+po saline), NR (icv saline+po NR), Aβ (icv Aβ+po saline), and Aβ+NR (icv Aβ+po NR).After the injection, to reduce Aβ clearance (Kang et al. Science. 2009;32 1005-7.) rats were subjected to 96 hours of sleep deprivation.Starting from day 6, rats were given either 700 mg/kg oral NR or saline, and handling test scores were recorded daily.The procedures were repeated daily until the rats were sacrificed on day 28.Behavioral experiments were randomly conducted at the end, and statistical analysis was performed using repeated measures ANOVA, followed by the Tukey post hoc test.

Results

Passive avoidance test results showed that the Aβ group had the shortest latency to enter the dark area. However, the Aβ+NR group exhibited a prolonged latency compared to the Aβ group (F(3,2)=5.5;p<0.05). Aβ injection induced depressive-like behavior in rats, as indicated by the forced swim test (FST) for behavioral despair and the sucrose preference test (SPT) for anhedonia. In AD rats treated with NR (Aβ+NR), Aβ-induced depressive-like behavior was reduced, with lower FST immobility scores (F(3,2)=6.2;p<0.05) and increased sucrose preference in the SPT (F(3,2)=7.5;p<0.05). There were no significant differences in anxiety-like behaviors among the groups, assessed by the time spent in the open arm in the elevated plus maze test (F(3,2)=1.9;p>0.05). During the 28-day monitoring period, the Aβ+NR group of rats exhibited a more rapid decrease in aggression levels compared to the other groups in the handling test. This decrease was significant between days 7 and 10 compared to the Aβ group (F(48,5)=1.5;p<0.05).

Conclusions

NR improved memory, reduced depressive behavior, and lowered aggression in AD rats. This suggests that NAD+ precursor NR effectively treats cognitive decline and neuropsychiatric symptoms in an AD model.

Treatment effect of trauma-focused treatment and/or integrated trauma-focused and personality disorder treatment on brain activation during an emotional face task
Authors: Aarts I. , Vriend C. , Van Den Heuvel O. A. , Thomaes K.
Published: August 2024

Introduction

Post-traumatic stress disorder (PTSD) and personality disorders are highly comorbid. There is some evidence that trauma-focused treatment normalises activation in brain areas involved in the fear circuit and regions involved in emotion regulation in people with PTSD. Although we assume that working mechanism of personality disorder treatments relies on improving emotion regulation and associated brain regions, there is as of yet little evidence of neurobiological effects of personality treatment on people with PTSD and comorbid PD.

Objectives

To 1) study the effect of trauma-focused and/or trauma-focused and personality disorder treatment n brain activation in participants with PTSD and comorbid personality disorders and 2) relate change in brain activation to symptom improvement.

Methods

Participants with PTSD and comorbid borderline and/or cluster c personality disorders from the PROSPER-trials (Prediction and Outcome Study for PTSD and personality disorders) were randomized to either trauma-focused treatment (TFT) or TFT with personality disorder treatment (TFT+PT). Brain activation was measured with an emotional face task during functional magnetic resonance imaging scanning before and after treatment. Regions of interest for the analyses were the amygdala, dorsal ACC, insula, ventromedial prefrontal cortex (PFC), ventrolateral PFC and dorsolateral PFC. Bayesian multilevel analyses were conducted to analyze change in brain activation. Clinical measures were clinician-administered PTSD severity, self-rated emotion regulation problems, depression severity and dissociation severity.

Results

We included 42 participants with a pre- and posttreatment scan (24 with TFT, 18 TFT+PT). Analyses on the pre-post data are currently being run and will be presented in April.

Conclusions

This is one of the first studies to conduct functional MRI analyses on treatment in participants with both PTSD and personality disorders.

The association between glucose 6-phosphate dehydrogenase (G6PD) deficiency and attention deficit/hyperactivity disorder (ADHD)
Authors: Krone B. , Newcorn J. , Manor I. , Merzon E.
Published: August 2024

Introduction

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked genetic enzymopathy that impacts 4.9% of the population, with greater prevalence among Mediterranean, East Asian, and African populations. G6PD deficiency results in levels of nicotinamide-adenine dinucleotide phosphate (NADPH) and glutathione (GSH) that are insufficient for maintaining the balance of oxidation-reduction in the body. This results in elevated production of reactive oxygen species (ROS), oxidative stress on proteins and lipids, damage to DNA, and potential activation of chemokine and cytokine pathways by astrocytes and microglia. We propose that these direct and indirect effects of G6PD deficiency are associated with development of ADHD.

Objectives

This study investigated the association between G6PD deficiency and Attention Deficit/Hyperactivity Disorder (ADHD).

Methods

The study involved 7,473 G6PD-deficient patients and 29,892 matched case-controls (selected at a 1:4 ratio) from a cohort of 1,031,354 within the Leumit Health Services database. Clinical characteristics were analyzed using Fisher’s Exact Tests for categorical variables and Mann-Whitney U tests for continuous variables.

Results

The average age of patients was 29.2 ± 22.3 years, with 68.7% being male. The mean follow-up duration was 14.3 ± 6.2 years. Individuals with G6PD deficiency showed a significant 16% higher risk of being diagnosed with ADHD (Odds Ratio (OR) = 1.16 [95% CI, 1.08-1.25], p < 0.001) on follow up. Furthermore, G6PD deficiency was associated with a 30% greater likelihood of seeking care from adult neurologists (OR = 1.30 [95% CI, 1.22-1.38], p < 0.001) and a 12% higher probability of consulting adult psychiatrists (OR = 1.12 [95% CI, 1.01-1.24], p = 0.048). The use of stimulant medications among G6PD deficient individuals was 17% higher for methylphenidate class drugs (OR = 1.17 [95% CI, 1.08, 1.27], p < 0.001), and use of amphetamines elevated by 16% (OR = 1.16 [95% CI, 1.03, 1.37], p = 0.047).

Conclusions

This study establishes a significant association between G6PD deficiency and an increased risk of ADHD diagnoses. These findings suggest potential opportunities for the development of culturally sensitive interventions.

Evaluation of Neurocognitive Functions of Children and Adolescents Diagnosed with Pediatric Bipolar Disorder and Disruptive Mood Dysregulation and at High Risk for Bipolar Disorder
Authors: Yenen Sivri I. , Çöp E. , Can K. C. , Yenen Menderes A. S.
Published: August 2024

Introduction

Pediatric Bipolar Disorder (BPD) is a chronic psychiatric disorder that alters normal and psychological development processes among patients. Although cognitive deficits in BPD have identified in recent studies, little is known about the developmental trajectory of these deficits. DMDD is a newly defined diagnosis included in the DSM-V. Since it added a new dimension to the clinical spectrum but few studies conducted on DMDD, there are some conflicting discussions in the literature about how to distinguish this disorder from other childhood psychiatric disorders and how to treat it.

Objectives

The aim of this study was to determine the phenomenological and neuropsychological differences between children and adolescents with a diagnosis of BPD (Pediatric Bipolar Disorder), DMDD (Disruptive Mood Dysregulation Disorder), and children and adolescents who are genetically at high risk for Bipolar Disorder (BD), and healthy controls (HCs) who do not have any psychiatric diagnosis, to investigate endophenotypes that may be predictive for BD.

Methods

Our study sample consists of four groups, the BPD group (n=30), the Risk group (n=25), the DMDD group (n=36), and the Healthy Control group (n=29). All participants were evaluated by the “Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children—Now and Lifetime Pattern (K-SADS-PL)”. “Young Mania Rating Scale/Parent Form (YMRS-ABF), Conner’s Parent Rating Scale (CPRS-48), Child and Adolescent Behavior Rating Scale (CBCL)” scales were filled by parents, and “Child Depression Inventory (CDI), Youth Self-Report Form for 11-18 Years Olds (YSR)” scales were filled by children and adolescents. Neurocognitive test battery was applied to each participant: Continuous Performance Test (CPT), Wisconsin Card Sorting Test (WCST), Stroop Color and Word Test (SCWT), Trait Making Test A and B sections (TMT-A/B), California Verbal Learning Test-Child version (CVLT-C).

Results

While it was determined that the cases in the BPD and DMDD groups performed significantly worse in CPT, SCWT, CVLT-C, TMT A/B tests compared to healthy controls, it was found that the subjects in the Risk group performed worse at the CPT test than healthy controls. In addition, the cases in the BPD, Risk and DMDD groups reported more clinical and behavioral problems than the healthy controls.

Conclusions

There is a significant deterioration in the areas of continuous attention, processing speed, cognitive flexibility, response prevention, verbal memory and working memory in the BPD and DMDD groups, and in the continuous attention area in the Risk group compared to healthy controls. Prospective follow-up and imaging studies using larger samples and a larger neurocognitive test battery in the future will better reveal the neuropsychological characteristics of the BPD, Risk and DMDD groups.

The psychosocial assessment of heart transplant candidates in Ireland
Authors: Corrigan K. , Crudden G. , Clarke A. M. , Doherty A. , Duffy R. , Azvee Z.
Published: August 2024

Introduction

We aim to describe the psychosocial features, including Stanford Integrated Psychosocial Assessment for transplantation (SIPAT) scores of individuals undergoing assessment for heart transplantation in Ireland.

Objectives

All potential heart transplant candidates undergo assessment of psychosocial criteria to enhance selection and improve transplant outcomes. The Mater Hospital Consultation Liaison Psychiatry (CLP) department provides this national service in Ireland. All potential heart transplant candidates should receive a biopsychosocial assessment and screening via SIPAT tool as per international best practice. The SIPAT is a psychosocial evaluation and risk assessment tool which can help to determine suitability for organ transplant and identify modifiable risk factors to optimise a patient for transplant. Lower scores represent higher rates of suitability with a score < 21 representing an acceptable candidate and ≥21 minimally acceptable.

Methods

We retrospectively examined the clinical files of all individuals referred to the national centre for heart transplant assessment over a five-year study period between January 2014 and December 2019.

Results

One-hundred and fifty four individuals were referred for heart transplant assessment with 79% (n=122/154) listed for a heart transplant. The most common indication for heart transplant assessment was non-ischaemic cardiomyopathy (48%, n=74/154). Of those listed for transplant, 74% (n=90/122) went on to receive a heart transplant. Of those undergoing assessment for heart transplant, 92% (142/154) were assessed by CLP and 94% (144/154) received social work assessment.

SIPAT scores were available for 64/154 individuals with 22% (14/64) deemed excellent candidates for transplant, 59% (38/64) deemed good candidates, 14% (9/64) minimally acceptable candidate and 5% (3/64) deemed high risk. The SIPAT domain breakdown was as follows: patient readiness (mean 3.9, SD 3.4); social support system (mean 2.9, SD 4.2); psychological stability (mean 5.1, SD 4.9); and substance use (mean 3.8, SD2.4), with an average total score of 16 (SD 12.4).

Post-transplant, 26% (23/90) were referred and seen by CLP, 53% (48/90) were referred to social work and 32% (29/90) required psychology services. Seventeen individuals (19%, 17/90) received a psychiatric diagnosis and 27% (24/90) were prescribed psychotropic medication in the post-transplant period.

Conclusions

This study describes for the first time the psychosocial factors and SIPAT scores of a national cohort of individuals referred for heart transplant. Psychiatric morbidity is high and this has implication for transplant suitability and post-operative course. This highlights the need for services to proactively identify and treat psychosocial factors in potential transplant recipients.

Development and validation of the Illness Representation Interview (IRI)
Authors: Kim D. Y. , Shin H. Y. , Choi S.
Published: August 2024

Introduction

It has been several years since the World Health Organization (WHO) advocated for shared decision-making(SDM) models when developing treatment plans for individuals with mental illnesses. It is emphasizing the importance of actively involving patients in expressing their opinions and sharing treatment-related information. However, few clinicians accept patients’ subjective views in clinical practice. Given that patients’ subjective beliefs about their symptoms significantly impact treatment satisfaction, prognosis, and adherence, it is essential to assess these perceptions. However, few studies have been conducted to assess patients’ subjective beliefs, their mental representation, of their disease. Therefore, this study aims to develop Interview that enable the utilization of patients’ cognitive representations of their mental illnesses in clinical practice.

Objectives

The primary objective of this study is to develop a semi-structured interview and a self-report scale to evaluate patients’ mental representations of their illnesses. Subsequently, validate the reliability and validity of these tools as psychological assessments.

Methods

An initial structure for both the semi-structured interview and self-report scale was established through a literature review of existing disease representation measurements. Subsequently, expert panel discussions and further literature reviews were conducted to refine the structure and content of both tools. Content validity for both the interview and self-report scale was assessed by a panel of nine experts and a group of ten students. Following this, the developed interview tool was subjected to a validity analysis with clinical patients using Missick’s six validity criteria(Content, Substantive, Structural, Generalizability, External, Consequential).

Results

Content validity index (CVI) values for the overall structure indicated that all subdomains scored above 0.8, demonstrating the appropriateness of the interview tool’s five subdomains: symptoms, causes, temporal aspects, impact, and treatment and control. Content validity assessment for individual items revealed that some items within the “causes of the disease” subdomain, specifically stress-related factors, scored below 0.6, prompting necessary item modifications. All other factors achieved CVI scores of 0.6 or higher. Facial validity assessment yielded favorable results for all items in the self-report scale. All validity was demonstrated to be satisfactory.

Conclusions

This study has provided evidence that the developed tools are reliable and valid instruments for measuring patients’ perceptions of their illnesses, offering a trustworthy means to assess these vital cognitive representations in clinical practice.

Exploring Causal Relationships in Mental Health Literacy Through Twitter Content: A Machine Learning Approach
Authors: Lien Y.-J. , Feng H.-P. , Chen C.-H. , Tseng Y.-H. , Tseng W.-H.
Published: August 2024

Introduction

The concept of Mental Health Literacy (MHL) is inherently multidimensional. However, the interrelationships among its various dimensions remain insufficiently elucidated. In recent years, the textual analysis of social media posts has emerged as a promising methodological approach for longitudinal research in this domain.

Objectives

This study aimed to investigate whether temporal causal associations exist between recognition of mental illness (R), mental illness stigma (S), help-seeking efficacy (HE), maintenance of positive mental health (M), and help-seeking attitude (HA).

Methods

Tweets were collocted at three distinct time points: T1, T2, and T3, spanning the period from November 1, 2021, to December 31, 2022. We employed a machine-learning approach to categorize the posts into five MHL facets. Using these facets, we trained a machine learning model, specifically Bidirectional Encoder Representations from Transformers (BERT), to determine the MHL scores. To be eligible, an account must have an R facet score at T1, and M, S, HE facet scores at T2, as well as an HA facet score at T3. In total, we retrieved 4,471,951 MHL-related tweets from 941 users. We further employed structural equation modeling to validate the causal relationships within the MHL framework.

Results

In the evaluation, BERT achieved average accuracy scores exceeding 89% across the five MHL facets in the validation set, along with F1-scores ranging between 0.75 and 0.89. Among the five MHL facets—maintenance of positive mental health, recognition of mental illness, help-seeking efficacy, and help-seeking attitudes—each demonstrated a statistically significant positive correlation with the others. Conversely, mental illness stigma exhibited a statistically significant negative correlation with the remaining four facets. In the analysis using single-mediation models, each of the individual mediator variables—namely, mental illness stigma, help-seeking efficacy, and maintenance of positive mental health—exhibited significant indirect effects. In the multiple-mediation model, two mediator variables—help-seeking efficacy and maintenance of positive mental health—demonstrated significant indirect effects. These findings suggested that the recognition of mental illness exerted an influence on help-seeking attitudes through one or more of these mediators.

Conclusions

By leveraging machine learning techniques for the textual analysis of social media and employing a longitudinal research design with panel data, this study elucidates the potential mechanisms through which the MHL framework influences attitudes toward seeking mental health services. These insights hold significant implications for the design of future interventions and the development of targeted policies aimed at promoting help-seeking behaviors.

Investigating Sex Differences in Opioid Use Disorder Risk Factors: Insights from Cross-Section Lebanese Study Population
Authors: Chamoun K. , Salameh P. , Sacre H. , Mouawad J. , Rabbaa L. , Megarbane B. , Hajj A.
Published: August 2024

Introduction

Opioid use disorder (OUD) is a significant public health concern, and understanding the risk factors associated with OUD is crucial for effective prevention and management strategies. However, limited information is available regarding the role of sex differences in OUD risk factors. Women have often been excluded from clinical studies to create more homogeneous samples and simplify the analysis of treatment effects. The underrepresentation of women in clinical trials and the lack of sex stratification, typically limited to binary comparisons without considering gender dynamics, raise concerns about potential sex disparities. Given the emerging evidence suggesting the possibility of sex differences in the likelihood of developing OUD, further research is needed to investigate and understand these potential disparities to optimize the individualized management of OUD.

Objectives

The primary objective of this study was to examine and identify any sex-related variations in OUD risk variables within the Lebanese community. By pinpointing sociodemographic, psychiatric, and other factors related to sleep and chronotype, we aim to elucidate their impact on the onset and progression of OUD in both males and females.

Methods

A cross-sectional study was conducted among 581 Lebanese adults using an online questionnaire that included sociodemographic questions, validated scales for substance use disorders and sleep disorders, and assessments for depression and anxiety. Multivariate analyses were performed to identify associations between risk factors and OUD scores in both male and female populations.

Results

Common risk factors for OUD were identified, including family and personal history of substance use disorder, co-occurrence of sedative and alcohol misuse, and psychiatric illnesses. Sex-specific risk factors were also observed. Among women, the ASSIST-opioids subscore was significantly associated with the Pittsburgh Sleep Quality Index (B=0.143) and Insomnia Severity Index (B=0.286) scores. Men demonstrated a correlation between ORT-OUD and younger age (B=0.882). Waterpipe consumption was negatively correlated with the ORT-OUD score in men (B=-0.018).

Conclusions

Our study emphasizes the importance of examining sex differences in risk factors for OUD, particularly within the Lebanese population. By acknowledging these gender-specific risk factors, interventions can be customized to address the distinct vulnerabilities of each sex. This approach could potentially improve prevention efforts, facilitate early identification, and implement treatment strategies tailored to the specific needs of individuals with OUD. Further research is needed to delve into the underlying mechanisms and develop targeted interventions for enhanced management of OUD.

Authors: del Río J. P. , Dabed F. , Díaz J. , Ladrón de Guevara A. , Gaspar P. , Maturana A. , Crisosto N.
Published: August 2024

Introduction

Polycystic Ovarian Syndrome (PCOS) is the most prevalent endocrine disorder in adolescents. It affects brain maturation, specially in highly neuronal plasticity periods However, there is a lack of information about the impact of this exposure during brain plasticity windows.

Objectives

Characterize the consequences of hyperandrogenism in emotional status and social cognition (SC) on adolescents daughters of women with PCOS (dPCOS).

Methods

Analytical cross sectional study. dPCOS and controls between ages of 12 to 25 years old were recruited. Participants underwent a complete clinical evaluation, plasmatic hormones determinations (including total testosterone, SHBG, androstenedione and 17-OH-progesterone) and ovarian ultrasound characterization. SC was estimated by: measurements of affects (PANAS), strength and difficulties (SDQ), self-reported empathy (EQ/SQ and AQ), and gaze patterns for autonomic response measurement via Eye-Tracking.

Results

33 participants were recruited, 15 cases and 18 controls. Median age was 17 and 18 years, respectively. The dPCOS presented a larger anogenital distance (cm) (9.7 vs 7.8; p=0.014), Ferryman-Gallwey score mean (13.0 vs 2.0; p=<0.001) and free androgen index value (7.5 vs 4.1; p=0.004), suggesting hyperandrogenism exposure during intrauterine and adolescence periods. Regarding SC, dPCOS exhibited a predominantly negative affective status (PANAS 8.0 vs 2.0, p=0.049) and a higher score in socio-emotional problems (SDQ 2,5 vs 1,5; p=0,047). The eye-tracking registration showed that dPCOS presentes longer time to first fixation in areas of interest (s) (0,35 vs 0,28; p=0,037), which was associated with a worse endpoint in emotional recognition (aR2=-0,920; f=19,48; Pr >|t|=<0,049). Furthermore, the 2D:4D ratio (intrauterine marker of androgen exposure) was correlated with a predominance of negative affect (rho=0,51; p=0,019) and less prosocial behaviors (coef=-2,39; P>|t|=0,049).

Conclusions

Clinical and hormonal markers suggest that dPCOS are exposed to hyperandrogenism during the most critical neuroplasticity periods. This exposure is associated with negative affects, more social-emotional difficulties and less score on emotional recognition and prosocial behavior. Due to a high psychiatric comorbidity in PCOS patients, these findings are relevant and emphasize the importance of early mental health treatment in these patients.

Premenstrual dysphoric disorder—an undervalued diagnosis? Preliminary results of a prospective study on Hungarian women
Authors: Pataki B. , Kiss B. L. , Juhász I. , Kálmán S. , Kovács I.
Published: August 2024

Introduction

The premenstrual dysphoric disorder (PMDD) is a new distinct diagnostic entity in the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). However, the severe premenstrual (PM) symptoms associated with PMDD result in functional impairment, globally, it remains highly underdiagnosed, underscoring the need for enhanced clinical recognition.

Objectives

This ongoing study aims to assess the prevalence and symptom profile of PMDD in a sample of Hungarian women. It is part of a comprehensive research process aiming to validate a prospective PMDD diagnostic questionnaire (Daily Record of Severity of Problems, DRSP) in order to facilitate the diagnosis of the disorder.

Methods

The study was performed in three steps. Firstly, retrospective data were collected from 112 women. Probable PMDD was assessed using the DSM-5 Based Screening Tool, while anxio-depressive symptoms and well-being were evaluated using the Beck Depression Inventory, the state subscale of the State-Trait Anxiety Inventory, and the WHO Well-Being Scale. Subsequently, prospective data were obtained from 9 women who completed the DRSP along with the aforementioned mood questionnaires during both their PM and follicular phases.

Results

In the first research phase, the sample was divided into women with probable PMDD diagnosis (PMDD group, n=68) and women without probable PMDD diagnosis (nonPMDD group, n=45) based on the DSM-5-Based Screening Tool. The PMDD group reported significantly more severe depressive (F(1; 56.2) = 19.394, p≤0.001) and anxiety (F(1; 35.6)=17.714, p≤0.001) symptoms and lower well-being (F(1; 44.3)=4.288, p=0.04) compared to the non-PMDD group, irrespective of the menstrual phase they experienced.

In the second and third research phases based on the DRSP, the sample was divided into women with probable PMDD diagnosis (PMDD group, n= 3) and those without probable PMDD diagnosis (nonPMDD group, n=6). A statistically significant association was observed between the classifications according to the DSM-5 Based Screening Tool and the DRSP (p=0.048; Cramer’s V=0.79). The PMDD group showed a tendency of lower well-being and more severe anxio-depressive symptoms than the nonPMDD group (Well-being: between phases p=0.93, between groups p=0.06; BDI-II: between phases p=0.79, between groups p=0.07; STAI-S: between phases p=0.87, between groups p=0.17).

Conclusions

The prevalence of PMDD was high in our sample. Women with probable PMDD retrospectively reported substantial affective difficulties and a decline in subjective well-being, regardless of their menstrual cycle. Prospective preliminary findings suggest a trend toward differentiation associated with probable PMDD. These results highlight the need for prospective clinical studies addressing the psychological symptoms of women with PM issues and the importance of appropriate treatment of the clinical appearance of PMDD.

The Global Burden of Suicidal Behavior Among People Experiencing Food Insecurity: A Systematic Review and Meta-analysis
Authors: Kaggwa M. M. M.
Published: August 2024

Introduction

Food insecurity has become a growing burden within a global context where climate change, catastrophes, wars, and insurgencies are increasingly prevalent. Several studies have reported an association between suicidal behaviors (i.e., suicide ideation, plans, and attempts) and food insecurity. This meta-analytic review for the first time, synthesized the available literature to determine the pooled prevalence of suicidal behaviors among individuals experiencing food insecurity, and examined the strength of their association.

Objectives

To determine the pooled prevalence of suicidal behaviors among individuals experiencing food insecurity, and examine the strength of their association.

Methods

Databases (Ovid, PubMed, Web of Science, and CINAHL) were searched using the appropriate search term from inception to July 2022. Eligible studies reporting the number/prevalence of suicidal behaviors among individuals experiencing food insecurity or the association between food insecurity and suicidal behaviors were included. The pooled prevalence of suicidal behaviors was determined using the random-effects model. The review was registered with PROSPERO (CRD42022352858).

Results

A total of 47 studies comprising 75,346 individuals having experienced food insecurity were included. The pooled prevalence was 22.3% for suicide ideation (95% CI: 14.7-29.9; I2=99.6%, p<0.001, k=18), 18.1% for suicide plans (95% CI: 7.0-29.1; I2=99.6%, p<0.001, k=4), 17.2% for suicide attempts (95% CI: 9.6-24.8; I2=99.9%, p<0.001, k=12), and 4.6% for unspecified suicidal behavior (95% CI: 2.8-6.4; I2=85.5%, p<0.001, k=5). There was a positive relationship between experiencing food insecurity and (i) suicide ideation (aOR=1.049 [95% CI: 1.046-1.052; I2=99.6%, p<0.001, k=31]), (ii) suicide plans (aOR=1.480 [95% CI: 1.465-1.496; I2=99.1%, p<0.001, k=5]), and (iii) unspecified suicide behaviors (aOR=1.133 [95% CI: 1.052-1.219; I2=53.0%, p=0.047, k=6]). However, a negative relationship was observed between experiencing food insecurity and suicide attempts (aOR=0.622 [95% CI: 0.617-0.627; I2 = 98.8%, p<0.001, k=15]). The continent and the countries income status where the study was conducted were the common cause of heterogeneity of the differences in the odds of the relationships between experiencing food insecurity and suicidal behaviors - with North America and high-income countries (HICs) having higher odds. For suicide attempts, all non HICs had a negative relationship with food insecurity.

Conclusions

There is a high prevalence of suicidal behaviors among individuals experiencing food insecurity. Initiatives to reduce food insecurity would likely be beneficial for mental wellbeing and to mitigate the risk of suicidal behaviors among population experiencing food insecurity.

The paradoxical finding of suicide attempts having a negative relationship with food insecurity warrants further research.

Authors: Bérdi M. , Hajduska-Dér N. , Sebők B. , Szeifert N. , Bálint L. , Szilágyi S.
Published: August 2024

Introduction

In Hungary, in contrast to most other countries, suicide deaths increased significantly during the first year of the COVID-19 epidemic (March to December 2020). Globally, the burden of emergency care in the healthcare system tended to decrease during the first period of the epidemic.

Objectives

Our research aimed to evaluate the changes in the number of intentional suicide attempts by violent and non-violent means during the first two years of the epidemic, compared to the trend before March 2020 in the Budapest metropolitan area and Pest County.

Methods

We analyzed psychiatric assessment reports of self-poisoning patients admitted to Péterfy Hospital’s Emergency Department and Clinical Toxicology from Jan 2019 to Dec 2021 to estimate non-violent suicide attempt trends. We analyzed patient data for violent suicide attempts treated at Dr. Manninger Jenő Trauma Centre from 2016-2021, focusing on trends during the first two years of the pandemic. Negative binomial regression estimates were used for interrupted time series analysis with Prais-Winsten regression, controlling for time and seasonal and autoregressive effects. We used change-point detection to examine the leveling of trends. The Institutional Review Board approved the research in both institutions. Approval numbers: 08-2022 (Péterfy Hospitaly) and 19-2021 (Traumatology Center).

Results

The number of male non-violent suicide attempts decreased by 16.6% compared with the pre-epidemic period (p<0.001). A similar and significant decrease was observed in females and in the total population (Image 1). The female and total population trends, i.e., the decrease, were reversed by August 2020, and the male trends were reversed by October 2020. The total number of patients treated for violent suicide attempts increased significantly (p<0.05) during the first two years of the pandemic (Image 2). There was a slight increase in violent attempts in men and a small decrease in women, but these changes are not statistically significant.

Conclusions

We hypothesize that those who tried to end their life through non-violent drug use were less inclined to seek assistance because they were concerned about being hospitalized during the COVID-19 outbreak. The surge in violent attempts is striking, as it correlates with the rise in suicide fatalities documented in Hungary during the initial year of the outbreak. Our data was obtained from two prominent public hospitals in Budapest, enabling us to conduct a more concentrated and thorough examination of the circumstances in the capital.

Introduction

Suicidal thoughts and behaviors (STB) are a serious public health problem. Suicide prevention programs have been established over the years, but many people who are suicidal do not seek treatment, and when they do, they end up in low-threshold sectors such as the Emergency Department in general hospitals. Previous studies about STB at the ED are mostly narrative, rather than a date-driven approach and limited in sample size .

Objectives

This study describes the prevalence and evolution over time of suicidal ideation (SI) and suicidal attempts (SA) in terms of sociodemographic, clinical and service use variables of the psychiatric patient referred to the Emergency Department of the University Hospital Gasthuisberg (Leuven, Belgium) over a 20 year period.

Methods

During a 20 year period (2002-2022), all patients with a psychiatric referral to the Psychiatric Emergency Department (PED) of the University Hospital Gasthuisberg (Leuven) were included (N˜18.000). We use descriptive statistics to summarize the data set, focusing on STB in terms of sociodemographic, clinical and service use variables.

Results

Around 1/10 patients presents with SA; another 1/5 with SI. Despite several reforms, SI and SA have remained relatively stable over the years. Notably, there is a higher prevalence of referrals for females in both SI and SA compared to males. However, there has been a notable increase in male SA cases over time. In the age group 36-49, both sexes exhibit the highest percentages of SI and SA cases, with exception for women in SI, where the age category 18-25 has the most referrals. Approximately one-third of male patients referred with STB have never accessed outpatient care, underscoring a critical gap in mental health services for this demographic.

Conclusions

Despite several reforms in mental health care, the PED remains a major entry point into mental healthcare for large proportions of STB patients.

Introduction

Alcohol and illicit drug use are highly prevalent among the homeless population. Religiosity and spirituality (RS) have been widely associated with lower substance use. However, evidence of this relationship among the homeless is still scarce.

Objectives

To assess the association between RS and the use of alcohol and illicit drugs among the homeless population of a large Brazilian urban center.

Methods

This cross-sectional study was conducted in São Paulo, Brazil. Aspects such as spirituality (FACIT-Sp12), religiosity (P-DUREL), religious-spiritual coping (Brief-RCOPE), and self-applied questions about current substance use (alcohol and illicit drugs) were evaluated. Adjusted Logistic Regression models were performed.

Results

A total of 456 homeless individuals were included, with an average age of 44.5 (SD=12.6) years. More than half of the participants used alcohol (55.7%) weekly and 34.2% used illicit drugs weekly. The adjusted Logistic Regression models identified that aspects of RS were associated with a lower propensity for alcohol and illicit drug use, whereas negative religious-spiritual coping strategies were associated with a higher propensity for the use of both.

Conclusions

The prevalence of alcohol and illicit drug use among participants was high. Positive RS and religious-spiritual coping were significant protective factors against the use of these substances. Conversely, negative religious-spiritual coping strategies were associated with risk factors.

Published: August 2024

Introduction

Benzodiazepine use disorder (BUD) has been associated with the presence of suicidal ideation (SI) in general population. It seems there is an overall increase in the risk of attempting suicide due to the increase of impulsivity, rebound and withdrawal of those who use benzodiazepines(1). However, this association has been scarcely studied.

Objectives

To explore the prevalence, clinical features and factors related to lifetime SI in adults with BUD.

Methods

A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021. Adult patients who met criteria for active BUD were included. Patients with language barriers, cognitive impairments and those who were participating in any clinical trial were excluded. All patients were evaluated with an ad-hoc questionnaire, EuropASI (European Addiction Severity Index), BDI (Beck Depression Inventory) and HRQoL SF-36 (Health-related quality of life according to SF-36). Univariate and bivariate analyses were performed comparing BUD patients with or without SI.

Results

554 patients were included (65.2% males; M age 42.6±12.6 years). SI was reported in 57.2% of the patients. Regarding the sociodemographic variables, any type of lifetime abuse was correlated with SI (67.8%, 73.5% and 77.8% of the patients with emotional, physical and sexual abuse respectively). Considering the different psychiatric features studied, having any psychiatric diagnosis increased SI up to 64%. Depressive and cluster B personality disorders were the ones with a higher presence of SI (67.1% and 68.1% respectively). Anxiety and cluster A personality disorders had also higher proportions of SI (56.1% and 58,7% respectively). Regarding the different assessment instruments used, a higher punctuation on BDI score was seen in the group of patients with SI (23.73±12.86). The scores also showed a worse perception of the mental quality of life of those people with SI, measured by HRQoL (13.76 and 36.82±31.93 in patients with SI and no SI respectively). Considering the EuropASI, there was an increased proportion of SI in those patients with a worse familiar situation (0.44±0.30), a higher alcohol consumption (0.26±0.28) and a worse psychological condition (0.48±0.24).

Conclusions

The prevalence of SI in patients with BUD is significative and is related to several clinical factors. Those factors should be taken into account in daily clinical practice, research, and any health policies on suicide. Further research should be developed.

The Effect of Depression on Smartphone Addiction: The Medicating Effects of Interpersonal Problem in Korean Adolescents
Authors: Seo Y. , Nam Y. , Lee J.
Published: August 2024

Introduction

Problematic smartphone use is twice as common among teenagers as it is among adults. Smartphone addiction is associated with anxiety, depression, attention deficit disorder, impulsivity, and sleep problems, among other issues.

Objectives

To assess whether interpersonal relationship problems mediate the relationship between smartphone addiction and depression among adolescents (ages 12-17) currently enrolled in middle and high school.

Methods

A cross-sectional study was conducted among 653 middle and high school students living in Wonju, South Korea between September 1 and November 30, 2019. Depression was measured by Center for Epidemiologic Studies Depression Scale (CES-D). In order to evaluate smartphone addiction, the Smartphone Addiction Scale Short Form Version (SAS-SV) was used. To examine interpersonal problems, the Korea Inventory of Interpersonal Problems Circumplex scale (KIIP-SC) was employed. We used the dplyr package to check for skew, kurtosis, and create density plots. Scatterplots and Pearson correlation analysis were used to examine the relationships between the main variables. For the mediation analysis, we used the 8 sub-scales of KIIP-SC (Domineering, Vindictive, Cold, Socially avoidant, Nonassertive, Exploitable, Overly Nurturant, Intrusive) as mediators and conducted a mediation analysis with 10,000 bootstrap samples using the lavaan package in R, version 4.2.2. Each analysis was evaluated based on a 95% confidence interval to determine significance.

Results

Depression, interpersonal problems, and smartphone addiction exhibited significant positive correlations with each other. The direct effect of smartphone addiction was found to be significant. The association between depression and smartphone addiction was mediated by the KIIP-HI (Nonassertive), the KIIP-JK (Exploitable) and the KIIP-NO (Intrusive).

Conclusions

Interpersonal problems mediate the relationship between depression and smartphone addiction. Identifying the high-risk group is essential for treatment strategy development.

A nosological approach to brief psychotic disorders and acute and transient psychoses
Authors: Coelho C. M.
Published: August 2024

Introduction

Acute and transient psychoses (International Classification of Diseases) and Brief Psychotic Disorders (Diagnostic and Statistical Manual of Mental Disorders) constitute heterogeneous nosological groups, which have undergone successive reformulations in the past decades, remaining doubts regarding their diagnostic validity and independence.

Objectives

This work aims to review the nosological evolution of these complex and neglected groups.

Methods

A review of the literature was conducted using PubMed and The Cochrane Library. The following terms were used: “acute and transient psychoses”; “brief psychotic disorders”; “cycloid psychosis”; “reactive psychosis”.

Results

Since the early 20th century, a group of non-affective psychoses with acute onset and brief duration have been described in different countries and under various names, such as bouffeé delirante, reactive psychosis or cycloid psychosis, denominations still present in ICD-9. In presente-day classifications, as ICD-10 and DSM-IV, an effort was made to homogenise the various regional and national concepts creating the group of ‘Brief Psychoses’ (DSM) or ‘Acute and Transient Psychotic Disorders’ (ICD). The marked heterogeneity and low diagnostic stability of these groups, mainly based on temporal criteria, has posed significant obstacles to further research and conceptualization. Given these difficulties, the latest revision of the International Classification of Diseases (ICD-11) brought about a substantial change, restricting this diagnosis to polymorphic psychotic conditions of acute onset and rapid resolution, subgroup with greater diagnostic stability and characteristics distinct clinical features.

Conclusions

The relevance of a better clarification for this nosological group is evident in the successive changes over the last century. ICD 11, once again, substantially changed the diagnostic criteria and the scope of this nosological entity, leaving doubts about the independent nature of this group, its connection to schizophrenia, as an attenuated form (more common in women and in developing countries), or even as a form of psychosis that is closer to affective disorders (due to its clinical evolution). Although little explored, this issue remains a source of doubt and interest, calling into question the Kraepelinian dichotomy for the so-called endogenous psychoses.
