Decreased Nesfatin-1 Level in Overweight Depressed Patients.

BACKGROUND: Nesfatin-1 (NF-1) is a parameter that has been shown to have an important potential in the modulation of the emotional state such as depression. The study focused to investigate the relationship between the plasma NF-1 level and depression. SUBJECTS AND METHODS: Seventy-three patients who have a major depressive disorder (MDD) and 71 healthy individuals participated in the study. Plasma NF-1 was analyzed by Enzyme Linked Immunosorbent Assay (ELISA) and compared according to the groups. RESULTS: The mean NF-1 was lower in the patients with MDD than being in the healthy (p:0.019). Plasma NF-1 level was statistically significantly lower in the overweight MDD than in the non-overweight MDD (p:0.024). We observed a negative correlation between plasma NF-1 level and age (r:-0.178, p:0.033), BMI (r:-0.212, p:0.011), HAM-D scores (r:-0.185, p:0.026). However, there was no correlation for smoking status in both groups (r:0.095, p:0.259). CONCLUSION: This study demonstrated the relationship between plasma NF-1 level and MDD as well as overweight. Therefore, NF-1 might be related to certain nervous system pathologies as well as adipose tissue in the body.

Brain-Derived Neurotrophic Factor and Oxidative Stress in Cannabis Dependence.

INTRODUCTION: Neurotrophin levels and oxidative stress markers such as ceruloplasmin and free thiols have been shown to contribute to pathophysiology in several psychiatric disorders. OBJECTIVE: Our aim is to evaluate whether those markers are altered in cannabis dependence. METHODS: Forty-five cannabis-dependent patients diagnosed according to the DSM-IV criteria and 45 healthy controls matched according to sex, age, BMI, and smoking status were enrolled. Brain-derived neurotrophic factor (BDNF), ceruloplasmin, lipid hydroperoxide, and total free thiols were measured in both groups. Those who had psychiatric comorbidities were excluded before sampling. RESULTS: We found significantly increased BDNF, ceruloplasmin, and lipid hydroperoxide, and decreased free thiol levels in patients with cannabis dependence. There is also a positive correlation between BDNF and lipid hydroperoxide (n = r = 0.472, p < 0.001) and a negative correlation between BDNF and total thiols (n = r = -0.412, p = 0.001). CONCLUSIONS: Increased BDNF might be a sign of impaired neuronal plasticity that is crucial for memory formation and adaptive response to drug addiction. Neuronal plasticity in the ventral tegmental area dopaminergic neurons was implied to play a role in substance addiction disorders, and these adaptations can be secondary to oxidative stress. Our findings, including increased lipid hydroperoxide, ceruloplasmin, and decreased free thiols, might support this hypothesis. In conclusion, cannabis dependency alters BDNF levels and increases oxidative stress.

Increased S100B Levels in Cannabis Use Disorder.

BACKGROUND: It has been determined that cannabis has adverse effects on brain tissue, and that increased S100 calcium binding protein B (S100B) blood levels are markers of neuronal damage. Therefore, the aim of this study was to evaluate the S100B levels in cannabis use disorder. METHOD: Thirty-two patients with cannabis use disorder and 31 matched healthy controls were enrolled in this study. Appropriate blood samples were taken from the enrolled subjects, and the serum S100B protein levels were measured with an electrochemiluminescence immunoassay for the quantification of the protein. FINDINGS: We found significantly increased S100B protein levels in patients with cannabis use disorder. The mean serum concentration of S100B was 0.081 ± 0.018 µg/l in patients with cannabis use disorder, and 0.069 ± 0.018 µg/l in the control group (p = 0.008). INTERPRETATION: Our data suggest that elevated S100B protein levels might indicate neuronal damage in the brains of people with cannabis use disorder.

Tracking down the footprints of bad paternal relationships in dissociative disorders: A diffusion tensor imaging study.

Preclinical studies indicate that stress early in life can cause long-term alterations in brain development. Studies have shown alterations in the brain functions of patients after experiencing trauma. Our aim is to examine whether the integrity of white matter tracts might be affected in dissociative disorder (DD) patients. A total of 15 DD patients and 15 healthy controls were studied, with the groups matched by age and gender. Diffusion-weighted echoplanar brain images were obtained using a 1.5 Tesla magnetic resonance imaging scanner. Regions of interest were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient and fractional anisotropy (FA) values of white matter were measured bilaterally in the anterior corona radiata (ACR) and by diffusion tensor imaging in the genu and splenium of the corpus callosum. Significantly lower FA values were observed in the right ACR of DD patients versus healthy individuals. We also found an association between bad paternal relationships and lower FA in the genu of the corpus callosum in female patients. Alterations in the right ACR suggest that diffusion anisotropy measurement can be used as a quantitative biomarker for DD. Paternal relationships may also affect the brain's microstructure in women with DD.

Methamphetamine intoxication and suicidal ideation/behavior in the emergency department.

BACKGROUND: This study investigates the association between Methamphetamine (MA) intoxication and suicidal ideation/behavior in patients presenting to emergency departments. Amidst rising MA use and co-use with opioids, this "twin epidemic" has manifested in increasing admissions for MA intoxication, often accompanied by psychiatric symptoms that can escalate to suicidal behaviors. METHOD: This retrospective study utilized patient records and analyzed data from 629 patients admitted to a Texas emergency department in 2020, with MA intoxication confirmed via urine tests and patient interviews. The suicidal tendencies were assessed using the Columbia-Suicide Severity Scale. The 629 patients were divided into three groups for analysis: Group I (n = 188), MA positive with suicidal ideation (SI) (MA + SI+); Group II (n = 202), MA-positive without SI (MA + SI-); and Group III (n = 239), MA-negative with SI (MA- SI+). Multiple regression analysis was used to elicit clinical features predicting patients presenting to the emergency department with acute MA intoxication. RESULTS: Results reveal that approximately half of patients with acute MA intoxication reported suicidal thoughts, indicating a significant association between MA use and suicidal tendencies. Females exhibited higher rates of suicidal thoughts, behavior, and subsequent medical attention compared to males. Sociodemographic characteristics and clinical features differed among MA-positive patients with and without SI. Multivariable regression analysis identified factors influencing MA use, including cannabis use, male gender, agitation, and an inverse association with alcohol use. Notably, the severity and potential lethality of suicidal behavior in MA-intoxicated patients paralleled those observed in psychiatric patients without MA use. CONCLUSION: These results underscore the urgent need for targeted interventions to address the complex interplay between MA use and suicidal risks in the emergency department setting, as well as broader public health strategies to combat the increasing prevalence of MA use.

Posttraumatic Stress Disorder Among Health Care Workers During the COVID-19 Pandemic.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has taken a significant toll on people worldwide, and in particular, on the health care workers (HCWs) who have worked on the frontlines in the fight against the pandemic. The goal of this study was to investigate the prevalence of posttraumatic stress disorder (PTSD) and related factors in HCWs in the era of COVID-19. METHODS: This cross-sectional survey study was conducted between September 15, and October 15, 2020, among HCWs in Turkey. The survey consisted of self-administered questionnaires, which included questions about sociodemographic variables, experiences caring for patients with COVID-19, and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), a trauma screening tool. The online survey was completed by 1833 HCWs. Univariate and multivariate logistic regression analyses were used to identify independent predictors of PTSD. RESULTS: The mean age of the participants was 32.7±7.0 years; 81.9% were physicians, and 56.5% were female. The rates of COVID-19 history in the respondents, a family member, or a coworker were 13.6%, 32.3%, and 12.6%, respectively. Among the HCWs who participated, 39.9% met the criteria for PTSD. Compared with the physicians, the nonphysician HCWs had a higher rate of PTSD (49.5% vs. 36%) (P<0.001) and higher PCL-5 scores (53.31±19.6 vs. 42.5±20.3) (P<0.001). In addition, 9.7% of the surveyed HCWs reported having suicidal ideation during the COVID-19 pandemic. Independent predictors of PTSD in HCWs were working on a COVID-19 unit, feeling isolated, suicidal ideation, being a nonphysician HCW, fear of spreading coronavirus to family, female sex, and a history of having COVID-19. CONCLUSIONS: HCWs were at risk for impairment in mental well-being in the era of COVID-19, with a significant number experiencing PTSD as well as suicidal ideation. Therefore, HCWs, especially those who are working on a COVID-19 unit and are female, should be monitored regularly for PTSD.

Melatonin Receptor Gene Polymorphism in Bipolar-I Disorder.

BACKGROUND AND AIM: In patients with Bipolar-I Disorder (BD-I), circadian rhythm and sleep disorders are frequently observed. Melatonin is a main regulatory hormone for the circadian rhythm. Certain studies have shown the relationship of melatonin receptor gene polymorphism with psychiatric diseases. In this study, it was aimed to investigate the relationship between BD-I and -184T>C (rs2119882) polymorphism in melatonin receptor 1A (MTNR1A) gene and -1193C>T (rs4753426) polymorphism in melatonin receptor 1B (MTNR1B) gene. METHODS: The study included 108 patients diagnosed with BD-I and 95 healthy people as the control group. Real-time PCR (RT-PCR) method was used to evaluate the polymorphism of MTNR1A gene-184T>C. Genotyping of MTNR1B gene-1193C>T polymorphism was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: In terms of MTNR1B gene-1193C>T polymorphism, homozygous CC genotype was found to be increased in BD-I patient group compared to the control group (p <0.05). Similarly, a statistically significant difference was found between the patients and the control group in terms of allele frequencies too (p <0.05). However, no relation between BD-I and MTNR1A gene-184T>C polymorphism was found (p >0.05). CONCLUSION: The results of the study revealed that MTNR1B gene-1193C>T polymorphism may play a role in BD-I genetic etiology and may be among the causes of sleep disorder and circadian rhythm disorder seen in these patients.

MicroRNA dysregulation in manic and euthymic patients with bipolar disorder.

BACKGROUND: Bipolar disorder (BPD) is a major psychiatric disorder with an unclear pathophysiology. Peripheral blood samples are easily drawn, making them are good candidates for diagnosing diseases. MicroRNAs are small non-coding RNA transcripts that regulate gene expression by binding to the 3'- UTR of mRNAs and directing their degradation. The aim of this study was to use blood plasma to investigate microRNA dysregulations in bipolar manic and euthymic patients. SUBJECTS AND METHODS: Blood samples were collected from 58 patients with bipolar I disorder (19 manic, 39 euthymic) and 51 healthy controls. RESULTS: Four microRNAs (miR-29a-3p, p = 0.035; miR-106b-5p, p = 0.014; miR-107, p = 0.011; and miR-125a-3p, p = 0.014) were upregulated in the entire bipolar group, compared to the healthy controls. Seven microRNAs (miR-9-5p, p = 0.032; miR-29a-3p, p = 0.001; miR-106a-5p, p = 0.034; miR-106b-5p, p = 0.003; miR-107, p < 0.001; miR-125a-3p, p = 0.016; and miR-125b-5p, p = 0.004) were more upregulated in bipolar manic patients compared to the healthy controls, and two microRNAs (miR-106a-5p, p = 0.013, and miR-107, p = 0.021) showed statistically significant upregulation in the manic patients compared to the euthymic patients. CONCLUSIONS: Our results showed greater miRNA dysregulation in the manic patients than in the euthymic patients. Two microRNAs could be more selective for bipolar manic episodes. Future studies should include depressive patients along with euthymic and manic patients.

Evaluation of Oxidant/Antioxidant Status and Cytokine Levels in Patients with Cannabis Use Disorder.

OBJECTIVE: Cannabis is the most commonly used illegal drug in the world and it has several adverse effects such as anxiety, panic reactions and psychotic symptoms. In this study, we aimed to evaluate oxidant, anti-oxidant status and cytokine levels in individuals with cannabis use disorder. METHODS: Thirty-four patients with cannabis use disorder and 34 healthy controls were enrolled to the study. Serum total antioxidant status, total oxidant status and cytokine levels were investigated in patients with cannabis use disorder and healthy controls. RESULTS: We found increased levels of total oxidant status, oxidative stress index and interleukin (IL) 1ß, IL-6, IL-8, and tumor necrosis factor (TNF) α in individuals with cannabis dependency compared to healthy people. When we compared total antioxidant status, IL-12, and interferon (IFN) γ levels, there were no differences in both groups. There was positive correlation between IL-6 and total oxidant status, oxidative stress index levels. CONCLUSION: The oxidative balance of individuals with cannabis use disorder was impaired and they had higher levels of IL-1ß, IL-6, IL-8, and TNF-α, which is a pro-inflammatory cytokine and indicates increased inflammation compared to healthy controls. Thus, these findings suggest that cannabis increased inflammation and impaired the oxidative balance.

Homocysteine Levels and Oxidative Stress Parameters in Patients With Adult ADHD.

OBJECTIVE: In our study, we aimed to evaluate the plasma homocysteine levels and oxidative stress parameters in patients with adult ADHD (A-ADHD). METHOD: Blood samples were taken from 32 A-ADHD patients and 32 controls enrolled in the study and plasma homocysteine, serum folate, vitamin B12, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were determined. Results were compared between the groups. RESULTS: Patients' plasma homocysteine level was significantly lower and serum folate level was significantly higher than the controls. The means of plasma homocysteine and folate levels were statistically significantly different between the groups ( p < .05). However, a statistically significant difference was not detected between groups for mean serum vitamin B12, TAS, TOS, and OSI levels ( p > .05). CONCLUSION: Our study suggests that oxidative balance is not impaired in A-ADHD, and contrary to other psychiatric disorders, homocysteine levels were found to be lower.

Investigation of Dysregulation of Several MicroRNAs in Peripheral Blood of Schizophrenia Patients.

OBJECTIVE: The prevalence of schizophrenia is 1%, and it is a debilitating disorder that often results in a shortened lifespan. Peripheral blood samples are good candidates to investigate because they can be easily drawn, and they are widely studied in psychiatric disorders. MicroRNAs are small non-coding RNA transcripts. They regulate the expression of genes by binding to the 3'-untranslated region (UTR) of mRNAs and pointing them to degrade. In this study, we aimed to investigate the expression of miR-9-5p, miR-29a-3p, miR-106-5p, miR-106b-5p, miR-107, miR-125a-3p, and miR-125b-3p in schizophrenia patients and healthy controls. METHODS: We collected blood samples from 16 patients with schizophrenia and 16 healthy controls. MicroRNAs were measured with reverse transcriptase polymerase chain reaction. RESULTS: Schizophrenia patients showed statistically significant upregulation of five microRNAs: miR9-5p (p=0.002), miR29a-3p (p＜0.001), miR106b-5p (p=0.002), miR125a-3p (p＜0.001), and miR125b-3p (p=0.018). CONCLUSION: Our results increased the value of the miR106 and miR29 families as potentially and consistently dysregulated in psychiatric disorders. Our results should be considered preliminary, and they need confirmation in future studies with larger sample sizes.

Microstructural Changes of Anterior Corona Radiata in Bipolar Depression.

OBJECTIVE: In bipolar disorder, dysregulation of mood may result from white matter abnormalities that change fiber tract length and fiber density. There are few studies evaluating the white matter microstructural changes in bipolar I patients (BD) with depressive episodes. The present study aimed to evaluate anterior corona radiata in BD patients with depressive episode using Diffusion Tensor Imaging (DTI). METHODS: Twenty-one patients with bipolar depression and 19 healthy controls were investigated and groups were matched for age and gender. Diffusion-weighted echoplanar brain images (DW-EPI) were obtained using a 1.5 T MRI scanner. Regions of interest (ROIs) were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values of white matter were measured in the anterior corona radiata (ACR) bilaterally by diffusion tensor imaging. RESULTS: There was not a significant difference between groups of age and gender (p>0.05). Significantly lower FA was observed in bilateral ACR in bipolar patients with depression compared with healthy individuals. And there is significantly higher ADC values in the left frontal corona radiate in bipolar patients. CONCLUSION: White matter abnormalities can be detected in patients with BD using DTI. The neuropathology of these abnormalities is unclear, but neuronal and axonal loss, myelin abnormalities and reduced white matter fiber density are likely to be relevant.

Validity and reliability of the Turkish version of CRAFFT Substance Abuse Screening Test among adolescents.

AIM: This study aimed to validate the CRAFFT diagnostic test, against the Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition, Axis 1-based diagnostic inventory in a Turkish population of adolescents. METHOD: The 124 adolescents who were 15-18 years old were enrolled to this study. CRAFFT was self-administered. Interviews took approximately 30 minutes, including the DSM-IV diagnostic interview for alcohol/drug dependence. RESULTS: The mean age of subjects was 16.653 years (minimum: 15 years, maximum: 18 years). A score of 2 or higher in part B was found to be optimal for detecting youths with substance dependence problems (sensitivity: 0.82; specificity: 0.88) and it was sufficiently discriminative. CONCLUSION: The CRAFFT is a valid and reliable instrument for identifying Turkish-speaking youths at risk for substance use disorders.

Evaluation of oxidative and antioxidative parameters in generalized anxiety disorder.

Generalized anxiety disorder (GAD) is a prevalent psychiatric disorder. The exact causes of GAD still unknown, in addition to neurochemical and neuroanatomic disorders, genetic and environmental factors are discussed in etiology. In our study we aimed to evaluate the oxidative metabolism's status and investigate the role of oxidative metabolites in GAD. Blood samples were taken from enrolled subjects in appropriate way and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were studied in Harran University Biochemistry Labs. Results were compared between groups. The patients' TOS and OSI levels were significantly higher than control group. The patients' TAS levels were significantly lower than controls'. According to our findings, oxidative stress mechanism might have a role in GAD pathophysiology. In the future, total antioxidants may be used as a biologic marker in GAD etiology but more research is needed.

Microribonucleic acid dysregulations in children and adolescents with obsessive-compulsive disorder.

AIM: Obsessive-compulsive disorder (OCD) is a disorder characterized by the presence of obsessions and/or compulsions. Although disorder etiology and pathogenesis remains unknown, several theories about OCD development have been proposed, and many researchers believe that it is caused by both genetic and environmental factors. In the current study, our aim was to investigate miRNA levels in OCD. METHODS: In the current study, we evaluated miR18a-5p, miR22-3p, miR24-3p, miR106b-5p, miR107, miR125b-5p, and miR155a-5p levels in child and adolescent OCD patients. The research sample consisted of a group of 23 OCD patients and 40 healthy volunteer controls. RESULTS: There was no significant difference in age and sex between the two groups (P>0.05). The levels of miR22-3p, miR24-3p, miR106b-5p, miR125b-5p, and miR155a-5p were significantly increased in the OCD subjects (P≤0.05). There were no statistically significant differences in miR18a-5p or miR107 levels between groups (P≥0.05). CONCLUSION: There could be a close relationship between levels of circulating miRNAs and OCD. If we could understand how the signaling pathways arranged by miRNAs impact on central nervous system development, function, and pathology, this understanding could improve our knowledge about OCD etiology and treatment.

Evaluation of several micro RNA (miRNA) levels in children and adolescents with attention deficit hyperactivity disorder.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent childhood disorders, although disorders etiology and pathogenesis remains unknown, several theories about ADHD development have been proposed and many researchers believe that it is caused by both genetic and environmental factors. In this study we evaluated miR18a-5p, miR22-3p, miR24-3p, miR106b-5p, miR107, miR125b-5p and miR155a-5p levels in child and adolescent ADHD patients. The research sample consisted a group of 52 ADHD patients, and 52 healthy volunteer controls. There was no significant difference in age and sex between the two groups (p>0.05). miRNA 18a-5p, 22-3p, 24-3p, 106b-5p and 107 levels were statistically significantly decreased in ADHD patients(p<0.05). miRNA 155a-5p levels were increased in patients group (p<0.05). The positive predictive value (PPV) and negative predictive value of miR107 was estimated for the cutoff point of 0.4480. PPV was 70% and NPV was 86.5% for the taken cut off point. There could be a close relationship between levels of circulating miRNAs and ADHD. If we could understand how the signaling pathways arranged by miRNAs, impact on CNS development, function and pathology this can improve our knowledge about ADHD etiology and treatment.
