Cannabidiol partially rescues behavioral, neuroinflammatory and endocannabinoid dysfunctions stemming from maternal obesity in the adult offspring

Maternal obesity is known to increase the risk of psychiatric disorders, such as anxiety, depression, schizophrenia and autism spectrum disorder in the offspring. While preventive measures are well-documented, practical approaches for addressing the damages once they are already established are limited. We have recently demonstrated the interplay between maternal obesity and treatment with cannabidiol (CBD) on neuroinflammation and peripheral metabolic disturbances during adolescence, however, it is known that both factors tend to vary throughout life. Therefore, here we investigated the potential of CBD to mitigate these alterations in the adult offspring of obese dams. Female Wistar rats were fed a cafeteria diet for 12 weeks prior to mating, and during gestation and lactation. Offspring received CBD (50 mg/kg) for 3 weeks from the 70th day of life. Behavioral tests assessed anxiety-like manifestations and social behavior, while neuroinflammatory and endocannabinoid markers were evaluated in the hypothalamus, prefrontal cortex (PFC) and hippocampus, as well as the biochemical profile in the plasma. CBD treatment attenuated maternal obesity-induced anxiety-like and social behavioral alterations, restoring exacerbated astrocytic and microglial markers in the hypothalamus, PFC and hippocampus of the offspring, as well as endocannabinoid levels in the PFC, with notable sex differences. Additionally, CBD attenuated plasma glucose and lipopolysaccharides (LPS) concentrations in females. These findings underscore the persistent influence of maternal obesity on the offspring's health, encompassing metabolic irregularities and behavioral impairments, as well as the role of the endocannabinoid system in mediating these outcomes across the lifespan.

Characterization of patients with major psychiatric disorders with AMPA receptor positron emission tomography.

Synaptic phenotypes in living patients with psychiatric disorders are poorly characterized. Excitatory glutamate α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) is a fundamental component for neurotransmission. We recently developed a positron emission tomography (PET) tracer for AMPAR, [11C]K-2, the first technology to visualize and quantify AMPARs density in living human brain. In this study, we characterized patients with major psychiatric disorders with [11C]K-2. One hundred forty-nine patients with psychiatric disorders (schizophrenia, n = 42; bipolar disorder, n = 37; depression, n = 35; and autism spectrum disorder, n = 35) and 70 healthy participants underwent a PET scan with [11C]K-2 for measurement of AMPAR density. We detected brain regions that showed correlation between AMPAR density and symptomatology scores in each of four disorders. We also found brain areas with significant differences in AMPAR density between patients with each psychiatric disorder and healthy participants. Some of these areas were observed across diseases, indicating that these are commonly affected areas throughout psychiatric disorders. Schizophrenia, bipolar disorder, depression, and autism spectrum disorder are uniquely characterized by AMPAR distribution patterns. Our approach to psychiatric disorders using [11C]K-2 can elucidate the biological mechanisms across diseases and pave the way to develop novel diagnostics and therapeutics based on the synapse physiology.

Glymphatic System and Psychiatric Disorders: A Rapid Comprehensive Scoping Review.

Since discovering the glymphatic system, there has been a looming interest in exploring its relationship with psychiatric disorders. Recently, increasing evidence suggests an involvement of the glymphatic system in the pathophysiology of psychiatric disorders. However, clear data are still lacking. In this context, this rapid comprehensive PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) scoping review aims to identify and analyze current evidence about the relation between the glymphatic system and psychiatric disorders. We conducted a comprehensive review of the literature and then proceeded to discuss the findings narratively. Tables were then constructed and articles were sorted according to authors, year, title, location of study, sample size, psychiatric disorder, the aim of the study, principal findings, implications. Twenty papers were identified as eligible, among which 2 articles on Schizophrenia, 1 on Autism Spectrum Disorders, 2 on Depression, 1 on Depression and Trauma-related Disorders, 1 on Depression and Anxiety, 2 on Anxiety and Sleep Disorders, 8 on Sleep Disorders, 2 on Alcohol use disorder and 1 on Cocaine Use Disorder. This review suggests a correlation between the glymphatic system and several psychiatric disorders: Schizophrenia, Depression, Anxiety Disorders, Sleep Disorders, Alcohol Use Disorder, Cocaine Use Disorder, Trauma-Related Disorders, and Autism Spectrum Disorders. Impairment of the glymphatic system could play a role in Trauma-Related Disorders, Alcohol Use Disorders, Cocaine Use Disorders, Sleep Disorders, Depression, and Autism Spectrum Disorders. It is important to implement research on this topic and adopt standardized markers and radio diagnostic tools.

Identification of novel genomic loci for anxiety symptoms and extensive genetic overlap with psychiatric disorders.

Anxiety disorders are prevalent and anxiety symptoms (ANX) co-occur with many psychiatric disorders. We aimed to identify genomic loci associated with ANX, characterize its genetic architecture, and genetic overlap with psychiatric disorders. We included a genome-wide association study of ANX (meta-analysis of UK Biobank and Million Veterans Program, n = 301,732), schizophrenia (SCZ), bipolar disorder (BIP), major depression (MD), attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorder (ASD), and validated the findings in the Norwegian Mother, Father, and Child Cohort (n = 95,841). We employed the bivariate causal mixture model and local analysis of covariant association to characterize the genetic architecture including overlap between the phenotypes. Conditional and conjunctional false discovery rate analyses were performed to boost the identification of loci associated with anxiety and shared with psychiatric disorders. Anxiety was polygenic with 12.9k genetic variants and overlapped extensively with psychiatric disorders (4.1k-11.4k variants) with predominantly positive genetic correlations between anxiety and psychiatric disorders. We identified 119 novel loci for anxiety by conditioning on the psychiatric disorders, and loci shared between anxiety and MD , BIP , SCZ , ADHD , and ASD . Genes annotated to anxiety loci exhibit enrichment for a broader range of biological pathways including cell adhesion and neurofibrillary tangle compared with genes annotated to the shared loci. Anxiety is highly polygenic phenotype with extensive genetic overlap with psychiatric disorders, and we identified novel loci for anxiety implicating new molecular pathways. The shared genetic architecture may underlie the extensive cross-disorder comorbidity of anxiety, and the identified molecular underpinnings may lead to potential drug targets.

Mental disorders of the depressive and anxiety spectrum in neuroendocrine tumors: prevalence, pathogenesis, clinical particulars

Neuroendocrine tumors (NETs) are a heterogeneous group of slowly progressing tumors from neuroendocrine cells able to secrete biologically active substances. The most striking clinical manifestation of functioning NETs is the carcinoid syndrome, which is caused by serotonin overproduction and is most often associated with hot flashes, diarrhea, and abdominal pain. The prevalence of depressive and anxiety spectrum disorders in NETs patients can amount to 30–50%. The development of depressive and anxiety spectrum disorders in NETs can occur both through a nosogenic mechanism facilitated by a long pre-diagnostic stage, the presence of a serious disease with severe somatic symptoms and resulting significant decrease in quality of life. The mental disorders may be a result of somatogenic factors, which include an imbalance of significant mediators in the central nervous system (in particular, serotonin), as well as chronic inflammation and abnormalities of the body's immune defense. In the treatment of patients with NETs and verified anxiety and depressive disorders, special attention is paid to the safety of prescribing the first-line therapy, the selective serotonin reuptake inhibitors. The side effects of these agents are related to the activity of serotonin receptor agonists in the gut, which results in diarrhea and increased gastrointestinal motility, the symptoms similar to the carcinoid syndrome manifestations. The accumulated evidence allows concluding on the relative safety of serotoninergic antidepressants in NETs patients, but does not exclude some groups of patients with an increased risk of complications related to an additional effect on serotonin metabolism. Current knowledge on the prevalence, pathogenesis and treatment of depressive and anxiety spectrum disorders, comorbid to NETs, are limited and contradictory. Therefore, further studies with a larger patient samples are required to identify key factors of the pathophysiology and manifestation of mental disorders in NETs patients, which would generally facilitate the optimization of their treatment.

The influence of exercise intensity on comorbid anxious behavior in psychiatric conditions

Many experts have extensively studied the potential of exercise as a treatment option for psychiatric conditions, including depression and autism spectrum disorder (ASD). Despite their core symptoms, these conditions exhibits comparable component traits, an anxiety. In this study, we explored the effect of exercise on behavioral abnormalities in psychiatric conditions, focusing on its intensity and emotional resilience. Shank3B knockout (KOSED) mice displaying self-injurious repetitive behavior and C57BL/6J mice, susceptible to stress as ASD and depression model, respectively, were subjected to moderate-intensity exercise (ME) for 2 weeks. ME mitigated the core symptoms (excessive grooming traits and behavioral despair) but did not exert a significant anxiolytic effect. Notably, exercise intensity has emerged as a critical determinant of its efficacy, as evidenced by a lower ventilation threshold and anxiolytic effect mediated by low-intensity exercise. The findings substantiate the notion that exercise is promising as a disease-modifying treatment, but intensity matters for emotional resilience.Graphical

Drug-related problems among breastfeeding patients treated for depressive spectrum disorders.

Depressive spectrum disorders are common and can hinder breastfeeding success. While medications typically pose minimal risk, the concerns persist. This is the first study that investigates the prevalence and characteristics of drug-related problems among breastfeeding mothers with depressive spectrum disorders. We analyzed those problems to understand their nature, severity, and contributing factors. Additionally, we evaluated the outcomes of pharmacist-led interventions in reducing them. Understanding drug-related problems is crucial for informing evidence-based practices to optimize both maternal mental health and breastfeeding success. This prospective observational study was conducted at a specialized pharmacy office in Poznan, Poland, which focuses on lactation support and medication consultations. 47 breastfeeding patients were enrolled. Pharmaceutical consultations were conducted according to Joint Commission of Pharmacy Practitioners Pharmacists' Patient Care Process standards. Novel MILC Questionnaire was used for efficient and optimal pharmaceutical interview. Drug-related problems were assessed basing on PCNE Classification System version 9.1. For adverse events in lactation, MedDRA v27 nomenclature was used; for causality, Naranjo Scale and LCAT were utilized. CTCAE was used for grading. Among the 47 patients, pharmacist identified 49 medication-related problems, with inadequate treatment effect due to underdosing or not taking the medication at all being the most common (57.1%). Pharmacist interventions focused on medication safety information and counseling. Overall, 78.7% of patients accepted these interventions, resulting in problem resolution for 71.4%. Twelve mothers (25.5%) reported adverse events in their infants, but after causality evaluation, only four (8.5%) might have been linked to maternal medication. None required medical intervention beyond one hospitalization for a serious adverse event possibly connected to maternal medication. The study identified high rates of drug-related problems among breastfeeding mothers with depression, primarily due to non-adherence. Pharmacist interventions significantly improved DRP outcomes. Adverse events were reported, but most were mild and did not require intervention. Our findings suggest that lactating mothers with depressive spectrum disorders may benefit from pharmacist-led support to optimize treatment adherence and address medication safety concern.

Mental health care use and quality among Medicaid adults with serious mental illness receiving care at Federally Qualified Health Centers vs. other settings

BackgroundFederally Qualified Health Centers (FQHCs) are a critical source of care for medically underserved populations and often serve as medical homes for individuals with serious mental illness (SMI). Many FQHCs provide mental health services and could facilitate access to mental health treatment within and outside of FQHCs. This study compared mental health care utilization and acute care events for adult Medicaid enrollees with SMI who receive care at Federally Qualified Health Centers (FQHCs) vs. other settings.MethodsThis study used the 2015–2016 Massachusetts All-Payer Claims Database to examine outpatient mental health care and acute care events for 32,330 Medicaid adults, ages 18–64 and with major depressive, bipolar, or schizophrenia spectrum disorders (SSD), who resided in FQHC service areas and received care from FQHCs vs. other settings in 2015. Multivariable linear regressions assessed associations between receiving care at FQHCs and outpatient mental health visits, psychotropic medication fills, and acute care events in 2016.ResultsThere were 8,887 (27.5%) adults in the study population (N = 32,330) who had at least one FQHC visit in 2015. Those who received care at FQHCs were more likely to have outpatient mental health visits (73.3% vs. 71.2%) and psychotropic medication fills (73.2% vs. 69.0%, both p < .05), including antidepressants among those with depressive disorders and antipsychotics among those with SSD. They were more likely to have ED visits (74.0% vs. 68.7%), but less likely to be hospitalized (27.8% vs. 31.9%, both p < .05). However, there was no significant difference in the likelihood of having an acute psychiatric hospitalization (9.5% vs. 9.8%, p = .35).ConclusionsAmong Medicaid enrollees with SMIs who had access to care at FQHCs, those receiving care at FQHCs were more likely to have outpatient mental health visits and psychotropic medication fills, with lower rates of hospitalization, suggesting potentially improved quality of outpatient care. Higher ED visit rates among those receiving care at FQHCs warrant additional investigation.

Tolerability and first hints for potential efficacy of motor-cognitive training under inspiratory hypoxia in health and neuropsychiatric disorders: A translational viewpoint.

Hypoxia is more and more perceived as pivotal physiological driving force, allowing cells in the brain and elsewhere to acclimate to lowered oxygen (O2), and abridged metabolism. The mediating transcription program is induced by inspiratory hypoxia but also by intensive motor-cognitive tasks, provoking a relative decrease in O2 in relation to the acutely augmented requirement. We termed this fundamental, demand-dependent drop in O2 availability "functional hypoxia." Major players in the hypoxia response are hypoxia-inducible factors (HIFs) and associated prolyl-hydroxylases. HIFs are transcription factors, stabilized by low O2 accessibility, and control expression of a multitude of genes. Changes in oxygen, however, can also be sensed via other pathways, among them the thiol-oxidase (2-aminoethanethiol) dioxygenase. Considering the far-reaching biological response to hypoxia, hitherto mostly observed in rodents, we initiated a translational project, combining mild to moderate inspiratory with functional hypoxia. We had identified this combination earlier to benefit motor-cognitive attainment in mice. A total of 20 subjects were included: 13 healthy individuals and 7 patients with depression and/or autism spectrum disorder. Here, we show that motor-cognitive training under inspiratory hypoxia (12% O2) for 3.5 h daily over 3 weeks is optimally tolerated. We present first signals of beneficial effects on general well-being, cognitive performance, physical fitness and psychopathology. Erythropoietin in serum increases under hypoxia and flow cytometry analysis of blood reveals several immune cell types to be mildly modulated by hypoxia. To obtain reliable information regarding the "add-on" value of inspiratory on top of functional hypoxia, induced by motor-cognitive training, a single-blind study-with versus without inspiratory hypoxia-is essential and outlined here.

Environmental pollution and extreme weather conditions: insights into the effect on mental health.

Environmental pollution exposures, including air, soil, water, light, and noise pollution, are critical issues that may implicate adverse mental health outcomes. Extreme weather conditions, such as hurricanes, floods, wildfires, and droughts, may also cause long-term severe concerns. However, the knowledge about possible psychiatric disorders associated with these exposures is currently not well disseminated. In this review, we aim to summarize the current knowledge on the impact of environmental pollution and extreme weather conditions on mental health, focusing on anxiety spectrum disorders, autism spectrum disorders, schizophrenia, and depression. In air pollution studies, increased concentrations of PM2.5, NO2, and SO2 were the most strongly associated with the exacerbation of anxiety, schizophrenia, and depression symptoms. We provide an overview of the suggested underlying pathomechanisms involved. We highlight that the pathogenesis of environmental pollution-related diseases is multifactorial, including increased oxidative stress, systematic inflammation, disruption of the blood-brain barrier, and epigenetic dysregulation. Light pollution and noise pollution were correlated with an increased risk of neurodegenerative disorders, particularly Alzheimer's disease. Moreover, the impact of soil and water pollution is discussed. Such compounds as crude oil, heavy metals, natural gas, agro-chemicals (pesticides, herbicides, and fertilizers), polycyclic or polynuclear aromatic hydrocarbons (PAH), solvents, lead (Pb), and asbestos were associated with detrimental impact on mental health. Extreme weather conditions were linked to depression and anxiety spectrum disorders, namely PTSD. Several policy recommendations and awareness campaigns should be implemented, advocating for the advancement of high-quality urbanization, the mitigation of environmental pollution, and, consequently, the enhancement of residents' mental health.

The relationship between anxiety symptoms and disturbances in biological rhythms in patients with depression

BackgroundBiological rhythms denote the cyclical patterns of life activities anchored to a 24-hour cycle. Research shows that depression exhibits disturbances in biological rhythms. Yet, the relationship between these biological rhythms and concomitant anxiety symptoms is insufficiently investigated in structured clinical assessments. MethodsThis multicenter study, carried out in four Chinese hospitals, comprehensively examined the relationship between anxiety and disruptions in biological rhythms among patients with depression. The study encompassed 218 patients diagnosed with depression and 205 matched healthy controls. The Chinese version of the Biological Rhythms Interview of Assessment in Neuropsychiatry was utilized to evaluate the participants' biological rhythms, focusing on four dimensions: sleep, activity, social, and diet. ResultsIn patients with depression, there is a significant positive correlation between the severity of anxiety symptoms and the disturbances in biological rhythms. The severity of anxiety and depression, along with the quality of life, are independently associated with disruptions in biological rhythms. The mediation model reveals that anxiety symptoms mediate the relationship between depressive symptoms and biological rhythms. ConclusionThis research highlights the role of anxiety within the spectrum of depressive disorders and the associated disturbances in biological rhythms. Our findings shed light on potential pathways towards more targeted preventive strategies and therapeutic interventions for individuals battling depression and anxiety.

Cannabidiol improves maternal obesity-induced behavioral, neuroinflammatory and neurochemical dysfunctions in the juvenile offspring

Maternal obesity is associated with an increased risk of psychiatric disorders such as anxiety, depression, schizophrenia and autism spectrum disorder in the offspring. While numerous studies focus on preventive measures targeting the mothers, only a limited number provide practical approaches for addressing the damages once they are already established. We have recently demonstrated the interplay between maternal obesity and treatment with cannabidiol (CBD) on hypothalamic inflammation and metabolic disturbances, however, little is known about this relationship on behavioral manifestations and neurochemical imbalances in other brain regions. Therefore, here we tested whether CBD treatment could mitigate anxiety-like and social behavioral alterations, as well as neurochemical disruptions in both male and female offspring of obese dams. Female Wistar rats were fed a cafeteria diet for 12 weeks prior to mating, and during gestation and lactation. Offspring received CBD (50 mg/kg) from weaning for 3 weeks. Behavioral tests assessed anxiety-like manifestations and social behavior, while neuroinflammatory and neurochemical markers were evaluated in the prefrontal cortex (PFC) and hippocampus. CBD treatment attenuated maternal obesity-induced anxiety-like and social behavioral alterations, followed by rescuing effects on imbalanced neurotransmitter and endocannabinoid concentrations and altered expression of glial markers, CB1, oxytocin and dopamine receptors, with important differences between sexes. Overall, the findings of this study provide insight into the signaling pathways for the therapeutic benefits of CBD on neuroinflammation and neurochemical imbalances caused by perinatal maternal obesity in the PFC and the hippocampus, which translates into the behavioral manifestations, highlighting the sexual dimorphism encompassing both the transgenerational effect of obesity and the endocannabinoid system.

Retrospective Chart Analysis of Psychiatry Referrals for Hospitalized COVID-19 Patients in a Dedicated COVID Hospital in a Metropolitan City in India

Abstract Background: The COVID-19 pandemic has been associated with multiple psychiatric problems in the general population as well as in those admitted with the infection. Studies done so far have mainly focused on the general population. It is important to address the needs and gaps in mental and psychological aspect of health of patients admitted with the infection to improve their overall prognosis. This study was undertaken with the aim to study the pattern of psychiatric referrals of hospitalized COVID-19 patients and to find out if there is any association between their socio-demographics, severity of COVID-19 infection, inflammatory markers, and co-morbidities. Materials and Methods: A descriptive, retrospective chart analysis of the record of 160 psychiatry referrals for COVID-19 patients seen by the on-call psychiatrist from May 2020 to October 2020 in a tertiary care hospital was undertaken. Sociodemographic data, severity of COVID-19 infection, blood investigation reports, psychiatric symptoms, diagnosis and management were recorded, tabulated, and analyzed using SPSS 20. Results: Referrals were more for individuals having moderate-to-severe COVID-19 infection, in elderly patients and in males. The most common reason for referral was disorientation (27.5%) and insomnia (27.5%), followed by the patient having a preexisting psychiatric illness (15%). The most common psychiatric diagnosis was delirium secondary to general medical condition, (28%), followed by anxiety and depressive spectrum disorders (23.75%). 32.5% of the patients referred had a past history of psychiatric illness, the most common being substance use disorder, followed by major depressive disorder and mixed anxiety depression. With the increase in the age of the individuals, the number of referrals for males was significantly more as compared to females (P = 0.00). No statistically significant association was found between age (P = 0.83), gender (P = 0.99), and psychiatric diagnosis. No significant association was found between the severity of COVID-19 and psychiatric diagnosis (P = 0.69). Conclusion: It is essential to screen for psychiatric disorders in patients admitted for COVID, as it goes a long way in reducing the overall morbidity and improves patient cooperation for various procedures which could be life-saving.

Attachment disturbance in women with depressive spectrum disorder, its connection with hostility

IntroductionThe results of the study of psychological factors of hostility in depression are presented. The topicality of the study is due to hostility considered, on the one hand, as a property of depression, and on the other hand, as a risk factor, associated with the likelihood of auto-aggressive behavior.ObjectivesThe aim of the study was to analyze the relationship between hostility and attachment disorders in endogenous depression.MethodsThe study involved 49 patients with depressive disorder (mean age 19,8±4,5). All patients were assessed using the Hamilton Depression Rating Scale (HDRS-17 mean 21,03±6,02). All completed the following methods: Revised Experiences in Close Relationships (ECR-R); Symptom Check List-90-Revised (SCL-90R); Aggression Questionnaire by Buss and Perry (BPAQ); I-structural test by G. Ammon (ISTA). According to the “depression” parameter of the SCL-90R, the group was divided into subgroups with high and medium severity of depression. Analysis of variance (ANOVA) or Mann-Whitney test were. Correlation analysis (Spearman) and stepwise multiple regression analysis were also used.ResultsAt high levels of depression, the indicators of “hostility”, “destructive” and “deficit aggression” are statistically significantly higher. The severity of depression significantly correlates with the severity of “anxiety” in attachment (close relationships), as well as with pathological “narcissism”, “destructive external self-delimitation”, “deficient internal self-delimitation”.For the measure of depression, regression analysis showed that the regression model explained more than 76% of the variance, with the measures of “interpersonal sensitivity”, “deficit narcissism”, and “avoidance” in attachment making significant contributions. For the “hostility” the regression model explains about 62% of the variance, while a significant contribution is made, as in the analysis of “depression”, by the indicators of “interpersonal sensitivity” and “avoidance”, however, unlike “depression”, the contribution of the “destructive narcissism” is noted in contrast to the “deficit narcissism”.ConclusionsWith severe depressive symptoms, indicators of hostility are increased. Hostility in depression is associated with factors caused by a violation of early interpersonal relationships (anxious attachment), which causes increased sensitivity in relations with others, “building a barrier” between oneself and the external environment perceived as hostile in the narcissistic pathology, problems in emotional regulation. One of the targets of psychotherapeutic work may be the ambivalence between desire for symbiotic dependence and the experienced hostility.Disclosure of InterestNone Declared

Prevalence of depressive disorders in breast cancer patients

IntroductionBreast cancer is the most common type of cancer and the leading cause of death from malignant neoplasms in women in Russia and in most countries in the world (Lima et al. EClinicalMedicine 2021; 38 100985). According to an analysis of the incidence and mortality from 36 cancers in 185 countries (Sung et al. CA Cancer J Clin 2021. 3 209-249) in 2020, 2261419 new cases of breast cancer were identified in the world in both sexes, which is accounted for 11.7% of the total cancer incidence. Mortality from breast cancer in 2020 amounted to 684996 cases. Patients with comorbid depression and anxiety disorders experience more severe symptoms, have longer recovery time, use more healthcare resources and have poorer outcome compare to those with cancer alone (Katon et al. Gen Hosp Psychiatry 2007; 2 147-155).ObjectivesAnalytical review of data on the impact of depressive spectrum disorders as comorbid conditions on the survival of breast cancer patients and their quality of life.MethodsThe following databases were searched for publications: PubMed, Embase, CINAHL, PsycINFO, Scopus, Science Citation Index/Social Sciences Citation Index, Cochrane Evidence Based Medicine database. The searches were limited to English language and studies with more than 100 subjects with diagnosed breast cancer where this information was mentioned. The analyzed period is between 1977 and 2018.ResultsThe reported prevalence of depression in breast cancer patients, according to researches, varies 4,5 to 38%. In patients with I-III stage breast cancer depression increased hazards of all-cause mortality by 50% compared to non-depressed patients. Stage-specific analyses demonstrated a 2–2.5 fold increase in breast cancer-specific and all-cause mortality in patients with stage I and II disease (Vodermaier et al. Breast Cancer Res Treat 2014; 2 373-384.). Women with non-metastatic breast cancer who report mild to moderate depressive symptoms in the weeks after surgery have approximately 2.5 times greater risk of death 8–15 years later than women who report little or no depressive symptoms post-surgery (Antoni et al. Gen Hosp Psychiatry 2017; 44 16-21). Depression in advanced cancer not only reduces quality of life but is also an independent predictor of poorer survival (Lloyd-Williams et al. J Affect Disord 2009; 113 127-132.).ConclusionsDepression and anxiety both have adverse effects on recurrence and all-cause mortality in patients with breast cancer. Untreated depression leads to significant increase in incidence and mortality. Depression can debut at any stage of cancer, including the stage of diagnosis. It proves the necessity for affective disorders screening in patients with cancer on the stage of diagnosis. Patients with diagnosed affective disorders should be observed not only by oncologist, but also by a psychotherapist in order to receive the necessary treatment to improve the quality of life and reduce the risk of mortality.Disclosure of InterestNone Declared

Neurodevelopmental Disorders and Suicide: A Narrative Review.

Specific risk factors for self-harm and suicide in children and adolescents with neurodevelopmental disorders (NDD) may differ from those in the general population within this age range. In the present review paper, we conducted a narrative analysis of the literature, aiming to establish a connection between suicide and affective disorders in children and adolescents with NDD. Emotion dysregulation (ED) as an individual factor and adverse childhood experiences (ACE) as environmental factors are discussed as risk factors for suicidality in all individuals with NDD. We propose a theoretical model in which ED and ACE can directly lead to self-harm or suicide, directly or indirectly by interacting with depressive spectrum disorders. Additionally, we suggest that specific risk factors are more frequently associated with each of the neurodevelopmental disorders listed in the DSM-V. This review underlines the key points useful to improve the knowledge of the trajectory leading to suicide risk in NDDs with the purpose to facilitate the early identification of the suicide risk.

Hair cortisol concentrations in pregnant women with bipolar, depressive, or schizophrenic spectrum disorders

PurposeMaternal cortisol levels in pregnancy may support the growth of or adversely affect fetal organs, including the brain. While moderate cortisol levels are essential for fetal development, excessive or prolonged elevations may have negative health consequences for both the mother and the offspring. Little is known about predictors of altered hypothalamic–pituitary–adrenal (HPA) axis activity during pregnancy. This study examined maternal hair cortisol concentration (HCC) in the 3rd trimester of pregnancy in relation to severe psychopathology.MethodsHair samples were collected from 69 women, 32 with a lifetime diagnosis of severe mental disorders (bipolar I or II disorder, moderate or severe depressive disorder, schizophrenic spectrum disorder), and 37 non-clinical controls. Hair samples were collected during the 3rd trimester, and liquid chromatography tandem mass spectrometry was used for cortisol assessment. Psychiatric diagnosis and current level of symptomatic functioning were assessed using the structured clinical interview from the DSM-5 and the global assessment of functioning scale.ResultsWomen with a lifetime diagnosis of severe mental illness had significantly elevated HCC compared to controls. Poorer current symptomatic functioning was also significantly associated with elevated HCC in pregnancy.ConclusionsThe implications of alterations in HCC on both maternal and infant health need further study.

Endoscopist experience with pediatric recurrent and intentional foreign body ingestion (RIFBI): Management considerations and future directions.

Accidental foreign body ingestion (FBI) is a common pediatric referral concern. In contrast, recurrent and intentional FBI (RIFBI) is infrequent and associated with greater endoscopic and surgical intervention in adults. Although pediatric guidelines exist for FBI, the risk and therapeutic implications of RIFBI are not addressed. An anonymous international survey on pediatric gastroenterologist experience with RIFBI was distributed. A 33-item REDCap© survey was distributed via email to pediatric gastroenterologists identified through mailing and email lists obtained from pediatric gastroenterology professional organizations. During 9-12/2021 we accrued 202 completed surveys. Respondents were from 27 countries and across the career span. Eighty percent reported experience with RIFBI; 74% reported seeing ≤ 3 patients with RIFBI within the past 24 months and 4% reported seeing ≥ 6. Of those who treated RIFBI, 38% reported an average number of annual ingestions per patient was ≥5. Frequent morbidity but not mortality was reported. Half reported adherence to FBI guidelines. Later-career endoscopists treated RIFBI more aggressively than accidental ingestion. Ninety-six percent noted that patients with RIFBI had psychiatric comorbidities. Providers at academic medical centers reported referring to behavioral health more than those in other settings. Most gastroenterologists surveyed reported encountering RFBI several times a year and in patients with psychiatric comorbidities. Greater likelihood of adverse outcomes associated with endoscopy was reported. Most reported referral to behavioral health and few had RIFBI management protocols. A broader spectrum of psychologic comorbidities in the pediatric population with RIFBI, notably depression and autism spectrum disorder, were reported.

Qualification and predictors of the development of affective disorders in multiple sclerosi

Affective disorders occupy one of the leading places in the structure of comorbidity in multiple sclerosis, but the questions concerning etiopathogenesis, qualification, diagnosis, and prediction of these disorders remain controversial. The most important consequences of affective disorders in MS include a decrease in the patient's quality of life, adherence to treatment, and their daily activities, and an increased risk of suicide and death from cardiovascular diseases. In this regard, the need for early detection and prediction of the development of depression in patients with MS is obvious. The following factors are considered among the predictors of the development of emotional distress and affective disorders: social, psychological, demographic, neurocognitive, and treatment-related factors, neuroimaging data, lifestyle features, comorbidities, characteristics of multiple sclerosis and its social implications. Specifically, younger age at the time of diagnosis, the presence of dyssomnia, fatigue, consumption of dairy products, atrophy of cortical areas in the frontal lobes, and decreased white matter volume of the uncinate fasciculus predict the development of depression. This article reviews the features of depressive and bipolar spectrum disorders in patients with MS.

Modulation of neural circuits by melatonin in neurodegenerative and neuropsychiatric disorders.

Neurodegenerative and neuropsychiatric disorders are two broad categories of neurological disorders characterized by progressive impairments in movement and cognitive functions within the central and peripheral nervous systems, and have emerged as a significant cause of mortality. Oxidative stress, neuroinflammation, and neurotransmitter imbalances are recognized as prominent pathogenic factors contributing to cognitive deficits and neurobehavioral anomalies. Consequently, preventing neurodegenerative and neuropsychiatric diseases has surfaced as a pivotal challenge in contemporary public health. This review explores the investigation of neurodegenerative and neuropsychiatric disorders using both synthetic and natural bioactive compounds. A central focus lies on melatonin, a neuroregulatory hormone secreted by the pineal gland in response to light-dark cycles. Melatonin, an amphiphilic molecule, assumes multifaceted roles, including scavenging free radicals, modulating energy metabolism, and synchronizing circadian rhythms. Noteworthy for its robust antioxidant and antiapoptotic properties, melatonin exhibits diverse neuroprotective effects. The inherent attributes of melatonin position it as a potential key player in the pathophysiology of neurological disorders. Preclinical and clinical studies have demonstrated melatonin's efficacy in alleviating neuropathological symptoms across neurodegenerative and neuropsychiatric conditions (depression, schizophrenia, bipolar disorder, and autism spectrum disorder). The documented neuroprotective prowess of melatonin introduces novel therapeutic avenues for addressing neurodegenerative and psychiatric disorders. This comprehensive review encompasses many of melatonin's applications in treating diverse brain disorders. Despite the strides made, realizing melatonin's full neuroprotective potential necessitates further rigorous clinical investigations. By unravelling the extended neuroprotective benefits of melatonin, future studies promise to deepen our understanding and augment the therapeutic implications against neurological deficits.
