RESUMEN

Lebanon, a small middle-income nation in western Asia, has been crippled by decades of political turmoil and armed conflict. A "quadruple crisis" hit the country over the past years, starting with the protracted humanitarian Syrian refugee crisis, followed by a severe socioeconomic collapse, the global COVID-19 pandemic, and lastly the Beirut port catastrophic blast. With the exposure to repetitive traumatic events and associated organic brain injury, the Lebanese population has become at a higher risk of addiction, among other psychiatric comorbidities. With the scarce statistics about the topic and limited addiction services in the country, collaborative local efforts and international help are urgently needed to fight the upcoming substance use epidemic. Raising awareness, providing adequate training, and securing resources for the management of both addiction and trauma are of utmost importance.

RESUMEN

The need for consultation-liaison psychiatry on COVID-19 wards has substantially increased since the start of the pandemic. In this cross-sectional study, we aimed to summarize the characteristics of patients admitted to the post-COVID-19 ward of the American University of Beirut Medical Center who received a psychiatric consultation. We collected relevant sociodemographic and medical data, information about past psychiatric history, psychiatry consultation details, hospital course, and disposition outcome. We also conducted chi-square and binary logistic regression analyses to assess the association between the different variables and disposition outcome. A total of 52 patients (mean age 57.33 years; equal gender distribution) were seen by the psychiatry consult-liaison team. Most had medical comorbidities and 21.2% required intubation. The most prevalent psychiatric diagnoses were delirium (30.8%), major depressive episode (15.4%), and other anxiety disorder (15.4%). Pharmacological management was implemented in 90.4% of cases and mainly included second-generation antipsychotics (36.5%). Non-pharmacological interventions consisted of those related to delirium and therapy for anxiety. Only intubation was significantly associated with disposition outcome (p = 0.004). This study highlights the various psychiatric themes emerging during the acute and post-acute periods of hospitalization for COVID-19. Hospitalized individuals recovering from the infection should be diligently screened and referred to the psychiatry consultation-liaison team to ensure the implementation of appropriate interventions.

RESUMEN

OBJECTIVE: Individuals with mental illness may fall victim to stigma. In this cross-sectional study, the authors aimed to explore correlates of stigma towards mental health in a Lebanese private university and its associated tertiary medical center. METHODS: The authors surveyed students, staff, and faculty at the American University of Beirut and its associated medical center. They assessed stigmatizing behaviors via the Reported and Intended Behavior Scale (RIBS), perceived stigma via the Perceived Devaluation and Discrimination Scale (PDDS), and attitudes towards collaborating with mental health professionals via the Doctors' Attitudes toward Collaborative Care for Mental Health (DACC-MH). RESULTS: A total of 270 participants (response rate of 18%) provided their responses. The mean scores on the RIBS and PDDS were 15.26 ± 4.75 and 32.25 ± 2.70, respectively. Participants who had higher scores on RIBS were more likely to be younger than 25 years of age (OR=1.869; p=0.026), to have a history of mental illness (OR=2.657; p=0.003), and to interact with individuals with a psychiatric disorder (OR=2.287; p=0.028). CONCLUSIONS: Results show a mixed pattern of stigmatizing behaviors and perceptions towards mental illness. This highlights the need for mental health awareness campaigns and interventions in the country.

RESUMEN

INTRODUCTION: Quarantine, although essential during contagious outbreaks, has been correlated with poor psychological outcomes in the general population. Such outcomes include low mood, suicide, and post-traumatic stress symptoms. Studies have mostly looked at the mental health of general citizens, healthcare workers, or infected survivors, with limited research targeting university students. This study aimed to understand the psychological distress experienced by self-quarantined undergraduate university students in Lebanon during the COVID-19 outbreak. METHODS: Undergraduate students enrolled at the American University of Beirut were invited to participate in a 47-item online questionnaire. 73 participants completed the questionnaire. Demographic data, data about COVID-19 exposure, stressors during quarantine, understanding the rationale, compliance, and difficulties associated with quarantine, and levels of psychological distress were analysed. RESULTS: 75.3% of the participants were considered as having a high risk of developing acute stress. Undergoing quarantine for more than 14 days, having a chronic medical illness, inadequate access to supplies, and fear of infection were all significantly associated with an increased risk of acute stress. CONCLUSION: Despite being a necessary preventive measure during infectious disease outbreaks, quarantine can be associated with negative psychological effects, particularly in undergraduate students. Providing preventive and effective interventions is of utmost necessity.KEY POINTSDuring COVID-19, three-quarter of students had high risk for acute stress.Females had higher odds of high-risk acute stress compared to males.Having a chronic medical condition was associated with high risk acute stress.Long quarantine and lack of supplies were associated with high risk acute stress.Providing interventions to protect the mental health of students is necessary.

RESUMEN

While the detrimental ramifications of the COVID-19 outbreak on the mental wellbeing of the general public continue to unravel, older adults seem to be at high risk. As the geriatric population continues to grow in the Middle East and North Africa (MENA) region, it is essential to explore the influence of this outbreak on geriatric mental health, a topic often neglected. In this review, we depict the status of geriatric psychiatry in the Arab countries of the MENA region, exploring the variations from one nation to another. While some have a null exposure to the field, resources and expertise in other countries range from very limited to extensive. Furthermore, we highlight the measures implemented in the Arab region to address mental health during the COVID-19 outbreak; these tend to be insufficient when targeting the geriatric population. Finally, we provide short- and long-term recommendations to stakeholders that aim at enhancing the mental healthcare of older adults in the Arab countries of the MENA region, particularly during this pandemic.

RESUMEN

INTRODUCTION: Management of obesity is challenging for both patients and healthcare workers. Considering the low success rate of current interventions, this study aimed to explore the prevalence and associated factors of night eating syndrome (NES), insomnia, and psychological distress among individuals with obesity in order to plan comprehensive obesity management interventions. METHODS: A cross-sectional study on a convenient sample from five primary healthcare centers in Port Said, Egypt, was conducted from November 2020 to March 2021. Sociodemographic and clinical characteristics were collected in addition to the assessment of NES, insomnia, and psychological distress using the Arabic versions of the Night Eating Diagnostic Questionnaire (NEQ), the Insomnia Severity Index (ISI), and the Patient Health Questionnaire-4 (PHQ-4) scales, respectively. Associations of NES, insomnia, and psychological distress were assessed by multiple regression analysis. We performed Bonferroni adjustments for multiple comparisons. RESULTS: We included 425 participants with obesity with a mean age of 45.52 ± 6.96 years. In all, 54.4% were females and the mean body mass index (BMI) was 35.20 ± 4.41 kg/m2. The prevalence rates of NES, insomnia, and psychological distress were 21.6% (95% CI: 17.7-25.6%), 15.3% (95% CI: 11.9-18.7%), and 18.8% (95% CI: 15.1-22.6%), respectively. NES was significantly associated with younger age (OR 0.974, p = 0.016), physical inactivity (OR 0.485, p = 0.010), insomnia (OR 2.227, p = 0.014), and psychological distress (OR 2.503, p = 0.002). Insomnia showed strong associations with NES (OR 2.255, p = 0.015) and psychological distress (OR 5.990, p < 0.001). Associated factors of psychological distress symptoms included insomnia (OR 6.098, p < 0.001) and NES (OR 2.463, p = 0.003). CONCLUSION: The prevalence rates of NES, insomnia, and psychological distress were high among primary care patients with obesity, and these conditions were interrelated. Optimal obesity management necessitates individualized and targeted multidisciplinary care plans that take into consideration individual patients' mental, behavioral, and dietary habits needs.

RESUMEN

Self-immolation is the act of setting fire to oneself. Recent spikes in self-immolation events have been noticed in the Arab world, specifically in the aftermath of the Arab Spring in 2011. We aimed to examine the literature assessing the characteristics and patterns of suicide by self-immolation in the Arab world. We registered our systematic review in Prospero. We searched PubMed, Medline, PsycInfo, Embase, and Scopus databases from inception until 9 July 2022, along with other sources, following the PRISMA 2020 guidelines. We collected relevant articles tackling suicide by self-immolation in the Arab world via title and abstract screening followed by full-text screening. We then conducted a narrative synthesis of the results. Out of 326 records from databases and 17 additional records identified through other sources, 31 articles (27 quantitative and 4 qualitative) were included. The studies came from Iraq (n = 16), Tunisia (n = 6), Kingdom of Saudi Arabia (n = 3), Jordan (n = 2), Libya (n = 2), Bahrain (n = 1), and Egypt (n = 1). The quantitative studies had a sample size ranging from 22 to 600 self-inflicted burn victims. Studies showed that self-immolators were mostly married women with low educational level and low socioeconomic status. Self-immolation was more likely to happen at home, usually following marital conflicts. Kerosene was the accelerant used the most. Depression was the most comorbid mental health diagnosis. Studies highlighted that self-immolation was being increasignly used as a form of protest. Self-immolation is not uncommon in the Arab world. Specific interventions directed at the population at risk are warranted.

RESUMEN

Narcolepsy type 1 (NT1) is the most common type of narcolepsy known to be caused by the loss of specific neurons responsible for producing peptide neurotransmitters (orexins/hypocretins), resulting in a sleep-wake cycle disorder. It is characterized by its association with cataplexy and abnormalities in rapid eye movement. To date, no cure has been established for this life-threatening condition. Misdiagnosis of NT1 is also quite common, although it is not exceedingly rare. Therefore, successfully identifying candidate serum biomarkers for NT1 would be a head start for accurate diagnosis and development of therapeutics for this disorder. This study aims to identify such potential serum biomarkers. A depletion protocol was employed for 27 human serum samples (16 NT1 and 11 healthy controls), followed by applying LC-MS/MS bottom-up proteomics analysis, then LC-PRM-MS for validation. The comparison of the proteome profiles of the low-abundant proteins in the samples was then investigated based on age, sex, sample groups, and the presence of the Human Leukocyte Antigen (HLA) DQB1*0602 allele. The results were tracked to gene expression studies as well as system biology to identify key proteins and understand their relationship in the pathogenesis of NT1. Our results revealed 36 proteins significantly and differentially expressed. Among the impaired pathways and bioprocesses, the complement activation pathway is impaired by six of the differentially expressed proteins (DEPs). They are coded by the genes C2, CFB, C5, C1R, C1S, and MASP1, while 11 DEPs are involved in Acute Phase Response Signaling (APRS), which are coded by the genes FN1, AMBP, APOH, CFB, CP, ITIH2, C5, C2, F2, C1, and ITIH4. The combined AUCs of the downregulated and upregulated DEPs are 0.95 and 0.76, respectively. Overall, this study reveals potential serum-protein biomarkers of NT1 and explains the possible correlation between the biomarkers and pathophysiological effects, as well as important biochemical pathways involved in NT1.

RESUMEN

INTRODUCTION: Posttraumatic stress disorder (PTSD) is a severe and disabling condition that can lead to functional impairment and decreased productivity. The purpose of this systematic review was to compile and evaluate existing research on PTSD in Lebanon and among Syrian refugees. METHOD: We searched the databases OVID Medline, EMBASE, and PsycINFO for articles that used validated tools to report the screening or diagnosis of PTSD among our population of interest. RESULTS: We included 102 articles out of a total of 10,367 screened manuscripts. We identified 24 studies discussing PTSD in the Lebanese population and 78 among Syrian refugees. A total of 90 studies described the epidemiological characteristics of PTSD while 12 assessed different treatment options. There was no significant difference in PTSD rates between males and females. We also identified several risks and protective factors for developing PTSD. The former included female gender, marriage, older age, and exposure to war. CONCLUSION: PTSD among Lebanese individuals and Syrian refugees is multifactorial in nature, but commonly involves war-related events. There is a significant evidence gap regarding intervention strategies in this population group. Targeted, multidisciplinary, and holistic interventions are required.

RESUMEN

Substance misuse is prevalent among older adults involved in the criminal justice system. The different classes of older offenders, primarily defined as individuals 50 years and older, as well as their offending behaviors vary in their association with substance misuse. Most prison health care systems do not adequately integrate substance use services. Screening for and treatment of substance misuse should be part of comprehensive mental health programs tailored to older offenders. This article reviews different types of offenses among older offenders, their association with substance misuse, and available treatment services.

RESUMEN

OBJECTIVE/BACKGROUND: This pilot study aims to assess the effect of Cognitive Behavioral Therapy for insomnia (CBTi) in individuals with cannabis use disorder and insomnia. It also aims to investigate the effect of CBTi on levels of serum inflammatory markers in relation to insomnia symptoms. METHODS/PATIENTS: Individuals with cannabis use disorder and insomnia symptoms were recruited over 18 months. Data collected included demographics, self-reported sleep parameters, and cannabis use. Blood samples were drawn to measure IL-2, IL-6, CRP, and cortisol. Participants completed the Insomnia Severity Index questionnaire (ISI) and the Patient Health Questionnaire-4 (PHQ-4), and they were provided with an actigraphy (wrist) device for 1 week before CBTi and a subsequent week after completing the 4 CBTi sessions. RESULTS: Nineteen participants were enrolled in the study. The mean ISI score decreased from moderately severe insomnia at baseline to no clinically significant insomnia after CBTi with a sustained decrease at 3- and 6-months follow-up. Actigraphy showed a significant decrease in sleep onset latency (SOL) after CBTi. Three months after CBTi, 80% of participants reported a decrease in their cannabis use. There was also a significant and sustained decrease in mean PHQ-4 scores after CBTi. Although only trending towards significance, the levels of three out of four biomarkers (IL-2, IL-6, CRP) were decreased 6 months after CBTi. CONCLUSIONS: CBTi is effective as a short- and long-term treatment of insomnia and comorbid anxiety/depression in individuals who regularly use cannabis. A potential added benefit is a reduction in cannabis consumption and inflammatory serum biomarkers.

RESUMEN

Schizophrenia is a chronic, debilitating mental illness that contributes significantly to the global burden of disease. Assertive outreach treatment for patients with schizophrenia and psychotic disorders has been implemented to improve treatment adherence and outcomes. The suitability of this model of care outside the western context has not been fully established. We describe the characteristics of 45 patients enrolled in the Psychosis Recovery Outreach Program (PROP), a program developed at a leading psychiatric facility in Lebanon. We collected twelve-month data for patients and used logistic regression models to identify predictor variables for enrollment in the service compared to those receiving standard treatment. Patients were mostly males (77.8%), younger than 39 years (80%), of college or higher education (68.2%), and diagnosed with schizophrenia (46.7%) or schizoaffective disorder (48.9%). About one-quarter (22.7%) had a comorbid cannabis use disorder. A majority received more than one oral antipsychotic (75.6%) while half (51.1%) were maintained on a long-acting injectable (LAI) antipsychotic. The following variables were significant predictors of enrollment in PROP: having a comorbid cannabis use disorder (OR 2.83 [1.25 - 6.37]), being prescribed a LAI antipsychotic (OR 9.99 [4.93-20.24]) or more than one oral antipsychotic (OR 4.57 [2.22-9.39]), visiting the emergency department more than once (OR 8.7 [2.64-28.68]), and admission to the psychiatry unit (OR 13.91 [3.17-60.94]). In addition, those following up in PROP were younger and less likely to be in the oldest age group (over 54 years) [OR 0.11 (0.01-0.93)], less likely to be females (OR 0.39 [0.18-0.81]), and less likely to be diagnosed with "other psychotic disorder" as compared to schizophrenia (OR 0.14 [0.03 - 0.62]). Our findings highlight that the assertive outreach model of care is applicable to its target population in the context of psychiatric care in Lebanon, namely young individuals with psychosis, higher comorbidities and a severe course of illness.

RESUMEN

The Beirut port explosion on August 4, 2020, traumatized the Lebanese population. It also revealed a lack of disaster mental health preparedness in a country subject to significant political, economic, and security challenges. The Trauma Assessment and Support Clinic at the American University of Beirut Medical Center was one of many initiatives set up nationally as a dedicated emergency benevolent service. The authors recommend anticipating the psychiatric consequences of such rare events at a professional and systemic level. The experiences of clinicians and the challenges faced in Lebanon can guide the improvement of disaster mental health care on a global level.

RESUMEN

Older adults are increasingly engaging in unhealthy substance use. Owing to aging and comorbid medical conditions, older adults are at increased risk of adverse effects from alcohol, tobacco, and illicit drug use. Preventative measures, regular screening, and appropriate intervention can protect older adults from the negative outcomes of substance use and potentially improve their quality of life. This article reviews the latest trends of substance use in older adults, impact on health, and the best practice approaches for the clinical assessment of substance use disorders in this age group.

RESUMEN

INTRODUCTION: A sustained-release tablet composed of a combination of the dopamine and norepinephrine reuptake inhibitor bupropion (BUP) and the µ-opioid receptor antagonist naltrexone (NAT) is marketed under the brand name Contrave by Orexigen Therapeutics for appetite control. Minimal literature is available regarding the use of combination bupropion and naltrexone (BUPNAT) in individuals with schizophrenia. AREAS COVERED: In this review, we propose a theoretical model where BUPNAT may have a therapeutic effect in the treatment of schizophrenia. We explore the pathways targeted by the constituent drugs BUP and NAT and summarize the literature on their efficacy and possible adverse effects. We then look at the potential use of BUPNAT in schizophrenia. EXPERT OPINION: Research has hinted that BUP's dopaminergic properties affect the same striatal pathways involved in schizophrenia. NAT, via opioid receptor antagonism, indirectly increases striatal dopamine release by disinhibiting nicotinic acetylcholine receptors. As such, we hypothesize that BUPNAT can have a therapeutic effect in schizophrenia, particularly on negative symptoms. We also suggest that it may ameliorate comorbidities frequently seen in this group of patients, including obesity, smoking, and substance use. Further research and clinical data are needed to elucidate the potential clinical benefits of BUPNAT in the treatment of schizophrenia.

RESUMEN

The proteome represents all the proteins expressed by a genome, a cell, a tissue, or an organism at any given time under defined physiological or pathological circumstances. Proteomic analysis has provided unparalleled opportunities for the discovery of expression patterns of proteins in a biological system, yielding precise and inclusive data about the system. Advances in the proteomics field opened the door to wider knowledge of the mechanisms underlying various post-translational modifications (PTMs) of proteins, including glycosylation. As of yet, the role of most of these PTMs remains unidentified. In this state-of-the-art review, we present a synopsis of glycosylation processes and the pathophysiological conditions that might ensue secondary to glycosylation shortcomings. The dynamics of protein glycosylation, a crucial mechanism that allows gene and pathway regulation, is described. We also explain how-at a biomolecular level-mutations in glycosylation-related genes may lead to neuropsychiatric manifestations and neurodegenerative disorders. We then analyze the shortcomings of glycoproteomic studies, putting into perspective their downfalls and the different advanced enrichment techniques that emanated to overcome some of these challenges. Furthermore, we summarize studies tackling the association between glycosylation and neuropsychiatric disorders and explore glycoproteomic changes in neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington disease, multiple sclerosis, and amyotrophic lateral sclerosis. We finally conclude with the role of glycomics in the area of traumatic brain injury (TBI) and provide perspectives on the clinical application of glycoproteomics as potential diagnostic tools and their application in personalized medicine.

RESUMEN

Coronavirus disease 2019 (COVID-19) was recently declared a pandemic by the WHO. This outbreak threatens not only physical health but also has significant repercussions on mental health. In recent world history, major infectious outbreaks were associated with severe mental health sequelae, including suicide. In this study, we systematically review the literature on suicidal outcomes during major international respiratory outbreaks, including COVID-19. We reviewed descriptive and analytic articles addressing suicide during major international respiratory outbreaks. We searched PubMed, Medline, Embase, Scopus, and PsycInfo databases and then utilized an independent method for study selection by a pair of reviewers. Two reviewers completed data abstraction and conducted a narrative summary of the findings. Our search generated 2,153 articles. Nine studies (three descriptive, five analytical, and one with mixed methodology) were eligible. The included studies were heterogeneous, divergent in methods, and with a low degree of evidence. Deducing an association between pandemics, suicide, and suicide-related outcomes remains thus poorly supported. Future research with better methodological characteristics, the use of longitudinal studies, and a focus on suicide as the primary outcome would allow for an in-depth understanding and formulation of the scope of this problem.
