Ten-year cardiovascular disease risk and related factors in lifetime marijuana use with comorbid methamphetamine-associated psychotic disorder: a QRISK®3 study.

BACKGROUND: Methamphetamine use and related direct and indirect problems are increasing all over the world. The coexistence of lifetime marijuana use (LMU) and methamphetamine use disorder (MUD) may also be accompanied by psychotic symptoms (MAP). Methamphetamine and marijuana use are known to pose risks for cardiovascular diseases (CVDs). However, ten-year CVD risk and inflammation markers of LMU-MUD (non-psychosis group) and LMU-MAP (psychosis group) subjects and the relationship of various sociodemographic and clinical variables with these markers have not yet been examined. METHODS: Thirty-two male subjects were included in non-psychosis group and 72 male subjects in psychosis group. Sociodemographic and clinical characteristics were recorded. Psychotic symptom severity of psychosis group subjects was measured. The ten-year CVD risk was calculated using QRISK®3 model. RESULTS: Age, cigarettes/pack-years, alcohol use onset age, drug use onset age, methamphetamine use onset age, duration of methamphetamine use, education and marital status of the groups were similar (p > 0.05). There was a statistical difference between the non-psychosis and psychosis groups in terms of self-mutilation history (p < 0.001), suicidal attempt history (p = 0.007), homicidal attempt history (p = 0.002), psychiatric hospitalization history (p = 0.010). Ten-year QRISK®3 score was 4.90 ± 9.30 in the psychosis group, while it was 1.60 ± 1.43 in the non-psychosis group (p = 0.004). The mean heart age of the psychosis group was 14 years higher than their chronological age, while the mean heart age of the non-psychosis group was 8 years higher. Neutrophil to lymphocyte ratio (NLR) (p = 0.003) was higher in the psychosis group. A significant correlation was detected between ten-year QRISK®3 and positive psychotic symptoms in the psychosis group (r = 0.274, p = 0.020). Regression analysis showed that self-mutilation history, NLR and relative risk obtained from QRISK®3 can be used to distinguish non-psychosis group and psychosis group subjects (sensitivity = 91.7; Nagelkerke R2 0.438; p = 0.001). CONCLUSIONS: This study is important as it demonstrates for the first time that among the subjects using marijuana and methamphetamine, those with psychotic symptoms have a higher NLR and ten-year CVD risk.

Leptin, Nesfatin-1, Orexin-A, and Total Ghrelin Levels in Drug-Naive Panic Disorder.

OBJECTIVE: This study aimed to examine the changes in serum nesfatin-1, leptin, orexin-A, and total ghrelin levels of patients diagnosed with drug-naive panic disorder (PD) before and after six weeks of the treatment and to compare the findings with the healthy subjects. METHODS: The neuropeptides were measured in venous blood samples taken from 32 patients and 32 healthy subjects. The blood samples of the patients who used paroxetine 20 mg/day plus alprazolam 0.5 mg/day were retaken again after six weeks. Measurements were performed with the Enzyme-Linked Immunosorbent Assay (ELISA) method. RESULTS: Serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were found to be significantly lower than the control group (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). When the serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were compared before and after treatment, significant differences were found in terms of orexin-A and total ghrelin levels (p=0.046, p<0.001, respectively). However, no significant differences were found in terms of nesfatin-1and leptin levels (p=0.205, p=0.988, respectively). CONCLUSION: This study reports that PD, like other anxiety disorders, may affect serum nesfatin-1, leptin, orexin-A, and total ghrelin levels, and there may be a relationship between PD treatment and the levels of these neuropeptides. The variability of this relationship among the neuropeptides examined indicates that various factors other than treatment play a role in this process.

Investigation of carotid intima-media thickness in patients with schizophrenia.

BACKGROUND: Patients with schizophrenia (SCZ) have a higher risk of cardiovascular diseases than the average population. Early diagnosis of SCZ patients with subclinical atherosclerosis is great importance in reducing cardiovascular morbidity and mortality. The aim of this study was to investigate some clinical risk factors for atherosclerosis in patients with SCZ. METHODS: Fifty-one SCZ patients (20 females, 31 males) and 55 healthy controls (HCs) (25 females, 30 males) were included in the study. Electrocardiography (ECG), lipid parameters, hemogram, and biochemistry values of the participants were taken. Low-density lipoprotein (LDL), high-density lipoprotein (HDL), fasting triglycerides, and total cholesterol were measured. The arrhythmogenic index of plasma (AIP) was analyzed. The recorded right and left carotid intima-media thickness (CIMT) measurements by carotid ultrasonography were scanned. RESULTS: QT interval (p = 0.035), CIMT-left (p = 0.008), CIMT-right (p = 0.002), fasting triglyceride (p = 0.005), AIP (p = 0.005) in the SCZ group compared to HCs (< 0.001) was statistically higher, while HDL (p = 0.003) was statistically lower. Smoking rates, QT interval (p = 0.035), CIMT-left (p = 0.008), and CIMT-right (p = 0.002) were significantly higher in the the SCZ group than in the HCs. According to odds ratios, individuals with SCZ have a 6.3-fold higher smoking rate. According to Pearson correlation analysis, CIMT-left was positively correlated with age and QT interval (r = 0.568, p < 0.001 and r = 0.589, p < 0.001, respectively). CIMT-right value was also positively correlated with age and QT interval (r = 0.533, p < 0.001 and r = 0.555, p < 0.001, respectively). QT interval positively and significantly predicted CIMT-left and CIMT-right (p < 0.001, ß = 0.549 and p = 0.001 and ß = 0.506 accordingly). CONCLUSION: In this study, a close relationship was found between the QT interval and CIMT in SCZ patients. This finding could be valuable for using an easy-to-calculate data such as QT in place of a laborious test such as CIMT.

Prevalence and determinants of post-traumatic stress disorder in patients with schizophrenia 2 years after an earthquake in Turkey.

OBJECTIVES: High rates of post-traumatic stress disorder (PTSD) have been observed in earthquake survivors many years after the event. However, its prevalence among patients with schizophrenia is largely unknown. This study, which was conducted two years after the 2020 Elazig earthquake, sought to identify risk factors for earthquake-related PTSD among patients with schizophrenia and healthy subjects. METHODS: Adult patients with schizophrenia (N = 103) and healthy subjects (N = 103) who had survived the earthquake were recruited from affected areas in the Eastern Anatolian Region of Turkey, Elazig. A detailed questionnaire of earthquake-related risk factors, the Brief Coping Orientation to Problems Experienced (Brief COPE), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Clinician-Administered PTSD scale for DSM-V (CAPS-5) scale were administered to participants. RESULTS: Twelve percent of the patients with schizophrenia and 25% of the healthy subjects had earthquake-related PTSD diagnoses two years after the 2020 Elazig earthquake. Healthy subjects had a significantly higher rate of earthquake-related PTSD when compared to patients with schizophrenia. Religious coping, self-blaming, less emotional support seeking, and going to a safer place on the night of the earthquake were found to be associated with PTSD in patients with schizophrenia. History of traumatic events, self-blaming, and less social support from family were found to be associated with a PTSD diagnosis in healthy subjects. CONCLUSIONS: The earthquake in Turkey created a situation such that significant symptoms of PTSD remained present at two years following the event in both patients diagnosed with schizophrenia and healthy subjects. Patients with schizophrenia have different risk factors for the development of PTSD when compared with healthy subjects. Clinical interventions should consider risk factors, coping strategies, and perceived social support when seeking to prevent earthquake-related PTSD.

Reduction in Retinal Ganglion Cell Layer, Inner Plexiform Layer, and Choroidal Thickness in Children With Autism Spectrum Disorder.

PURPOSES: The aim of this study was to evaluate the retinal nerve fiber layer (RNFL), choroidal layer, inner plexiform layer (IPL), and ganglion cell layer (GCL) in patients with autism spectrum disorder (ASD). METHODS: In this study, we measured the thickness of the RNFL, GCL, IPL, and choroidal thickness using a spectral optical coherence tomography (OCT) device and we compared the results between the children diagnosed with ASD and healthy controls. Correlation between the Childhood Autism Rating Scale (CARS) and the OCT data was evaluated. RESULTS: Both ASD and control group consisted of 40 subjects (30 males and 10 females). Of the children in the ASD group, 29 had normal intelligence and 11 had mild intellectual disability (MID). The mean age of patients in the ASD group and control groups were 9.77 ± 3.37 years and 9.85 ± 3.97 years (p = 0.928). There was a statistically significant difference between the ASD group and the control group in the nasal and nasal-superior sectors of the RNFL layers in the left eye when all the lower layers of RNFL were assessed. In both eyes, the children with ASD had considerably lower mean choroidal thicknesses than the controls. When compared to the controls, the GCL and IPL volumes in the individuals with ASD were considerably lower in both eyes. Compared to the MID group, the left GCL volume of the nasal-inferior group was noticeably higher. A significant correlation was found between CARS scores and left GCL left IPL. CONCLUSIONS: In contrast to RNFL in the ASD group, significant reductions in IPL, GCL, and choroidal thickness were observed in both eyes. It is thought that GCL may be a much more important biomarker than RNFL in terms of representing the structural deterioration in the brain. In addition, these results may form the basis for a new perspective on the use of OCT for the diagnosis and clinical course of autism.

Motor and somatosensory symptoms determine cognitive error levels in functional neurological symptom disorder/conversion disorder.

INTRODUCTION: The level of cognitive error in functional neurological symptom disorder (FNSD, conversion disorder) subtypes [psychogenic non-epileptic seizure (PNES), motor (M), PNES plus motor (PM), motor plus somatosensory (MS)] have not yet been investigated. AIM: We aimed to qualify the level of cognitive error in FNSD subtypes. MATERIALS AND METHODS: The disorder symptoms were assessed via the somatoform dissociation questionnaire (SDQ), the symptom check list-90-revised (SCL-90-R), and the global assessment scale (GAS). The cognitive distortions scale (CDS) was used to evaluate cognitive errors. RESULTS: Mean ages of groups were 28.37±6.99 years (PNES, n=24), 27.90±6.22 years (M, n=21), 30.36±7.86 years (PM, n=19), 31.38±9.02 years (MS, n=21), and 30.87±7.17 years (control, n=48) (p=0.377). In terms of the global severity index of SCL-90-R, there were significant differences between PNES and PM (p=0.003); PNES and MS (p0.999); PM and MS (p=0.172). There was no significant difference between the CDS-PA scores of the patient groups (p>0.05). CONCLUSIONS: Our study demonstrated that in FNSD, the somatosensory symptoms were more associated with cognitive errors related to interpersonal relationships than the motor symptoms and the motor symptoms were more than PNES.

Comparison of OCT findings of schizophrenia patients using FGA, Clozapine, and SGA other than Clozapine

ABSTRACT Objective: The effect of antipsychotic (AP) drugs on optical coherence tomography (OCT) findings in schizophrenia has not yet been fully elucidated. In this study, we aimed to investigate the effects of APs (the first generation antipsychotic group [FGAG], the second generation antipsychotic group [SGAG], the clozapine group [CG]) on OCT findings in schizophrenia. Methods: The thickness of the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), and choroidal thickness were measured using a spectral OCT device. Results: No significant difference was found between FGAG, SGAG, CG (p > 0.05) while there was a significant difference between the control group and the patients group in terms of RNFL, GCL, and IPL (p < 0.05). A significant difference between SGAG and CG, FGAG (p < 0.05); between control group and FGAG (p < 0.05) were found in terms of choroidal thickness. Conclusion: These findings suggested the deterioration of the metabolic parameters due to the SGA use. Thinner choroidal layer thickness in the CG compared to the SGAG and control group was thought to be related to the patients using clozapine had a resistance to the treatment.

Long-Term Substance Use Can Cause Irreversible Photopic Vision Changes in Substance Use Disorder in Remission.

OBJECTIVE: Substance use has such effects on pupil diameter. Although there is knowledge about the acute effects of substances on pupils, studies showing their chronic effects are limited. The aim of the present study was to evaluate the effect of long-term substance use on scotopic, mesopic, and photopic vision. METHODS: The present study with cross-sectional desgn was conducted at the Adiyaman Training and Research Hospital for Psychiatry in Adiyaman. This study involved 110 substance use disorder (SUD) patients and 46 healthy volunteers as the control. The parameters were measured and recorded automatically by a device. RESULTS: The mean age was 23.44±5.53 years in the SUD group and 24.26±5.38 years in healthy controls (p=0.420). The mean age of onset of the substance was 17.74±3.89 years and the mean duration of substance use was 3.54±2.9 years. It was determined that the patients had not used any substance for a mean of 121.73±117.49 days. There was no significant difference between patient and control groups in terms of scotopic and mesopic measurements of both eyes (p>0.05). Photopic measurements were significantly higher in the patient group than in the control group (p<0.05). Photopic measurements were significantly higher in the opioid, cannabis, ecstasy, and multiple substance use groups than in the control group (p<0.05). CONCLUSION: The most important topic of this study is that photopic vision is permanently impaired in patients with a history of chronic substance use. This was attributed to disrupted sympathetic-parasympathetic hierarchy.

Increases in retinal nerve fiber layer thickness may represent the neuroprotective effect of cannabis: an optical coherence tomography study.

Although optical coherence tomography (OCT) has been used in many neuropsychiatric disorders, data on substance use disorders (SUD) are not available. The aim of this study was to evaluate ganglion cell layer (GCL), inner plexiform layer (IPL), retinal nerve fiber layer (RNFL), and choroidal layer thickness in patients diagnosed with SUD especially cannabis use disorder (CUD). RNFL, GCL, IPL, and the choroidal layers of 111 patients diagnosed with SUD and 45 healthy controls were retrospectively analyzed. Fifty patients were diagnosed with CUD and 50 patients had multiple drug use (MDU). The mean age of the patient and control groups were 23.39 ± 5.53 and 28.48 ± 5.21 years, respectively. The mean duration of substance use was 3.53 ± 2.95 years. The patients had not used any substance for a mean of 121.45 ± 116.99 days. When the RNFL values of the SUD, MDU, and control groups were compared, no significant difference was found except for such components. However, there were significant differences in terms of right naso-superior (p = 0.020), right temporo-inferior (p = 0.024), right temporo-superior (p = 0.002), left naso-superior (p = 0.005), left naso-inferior (p = 0.043), and left temporo-superior (p = 0.008) between CUD and control groups. That is, RNFL values were higher in the CUD group than in the control group. Cannabis has medical uses because of its possible neuroprotective properties. Our study supports the possible neuroprotective effects associated with cannabis through RNFL data. According to our best knowledge, this is the first study investigating the association between RNFL and drugs, particularly cannabis.

Decreases in retinal nerve fiber layer thickness correlates with cumulative alcohol intake.

Alcohol and illicit drugs affect neurons through various mechanisms and are detected by neuroimaging techniques. The optical coherence tomography device has just been used in research on substance use disorders. In this study, we compared the retinal nerve fiber layer (RNFL), the ganglion cell layer (GCL), the inner plexiform layer (IPL), and choroid layer of alcohol use disorder (AUD) and healthy subjects. We included 38 male patients and 38 male healthy controls of similar age (p = .714) in the study, prospectively. Monthly income (p = .001) and stable employment (p = .001) were lower in the patient group. There was a significant difference between patient and control groups in terms of RNFL sectors, choroid, GCL, IPL values of both eyes were significantly different (p < .05). When the effect of age and liver damage was controlled in the patient group, a correlation was found between alcohol unit/year and nasal superior (r = -0.474, p = .004), temporal (r = -0.402, p = .015) sectors of the RNFL. The regression analysis indicated that the sensitivity and specificity of mean N (p = .060), mean choroidal thickness (p < .001), mean GCL (p = .013), and mean IPL (p = .017) related to the diagnosis of AUD were 78.9% and 81.6% (-2 Log likelihood = 57.57, Nagelkerke R2=0.622), respectively. Alcohol has neurotoxic effects, either directly or indirectly, with withdrawal. Our study results suggest that RNFL, the non-myelinated white matter tissue, can be a follow-up marker of neuronal damage due to cumulative alcohol intake.

Evaluation of TP-E Interval and TP-E/QT Ratio in Panic Disorder.

Background and Objectives: The autonomic nervous system (ANS) is involved in panic disorders. ANS dysfunction has been shown to be associated with ventricular arrhythmia and increased heterogeneity of ventricular repolarization. However, there remains limited evidence of the relationship between panic disorders and ventricular depolarization markers, including the Tp-e interval and Tp-e/QT ratio. This study aimed to evaluate ventricular repolarization parameters in patients with panic disorder. Materials and Methods: In total, 40 patients with panic disorder, diagnosed using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, were included in the study group. The control group comprised of 50 age- and sex-matched healthy individuals. A standard 12 lead electrocardiogram was recorded on all participants, and heart rate, QT interval, QRS duration, Tp-e interval, and Tp-e/QT ratio were measured. Results: QRS durations and QT intervals were similar in the study and control groups. Compared to the control group, QTd, Tp-e, and cTp-e intervals as well as Tp-e/QT and Tp-e/QTc ratios were significantly increased in patients with panic disorder (p < 0.05 for all). In the study group, the Severity Measure for Panic Disorder-Adult score had a significant positive correlation with the Tp-e interval (r = 0.369, p < 0001), cTp-e interval (r = 0.531, p < 0.001), Tp-e/QT ratio (r = 0.358, p = 0.001), and Tp-e/QTc ratio (r = 0.351, p = 0.001). Conclusion: These findings indicate that panic disorders are associated with increased ventricular repolarization heterogeneity, which may be attributed to ANS dysregulation.

Platelet to lymphocyte ratio (PLR) in alcohol use disorder.

Lymphocyte-related parameters in Alcohol Use Disorder (AUD) have recently been investigated. However, knowledge of platelet to lymphocyte ratio (PLR) in AUD is limited. In this study, we compared complete blood count values of 31 AUD male patients and 31 healthy male controls. There was no significant difference between the two groups in terms of PLR (p = .123). When the age was controlled, there was a negative correlation between the duration of alcohol use and PLR (r = -0.567; p = .005). The significance of the parameters in the AUD group was found to be related to the duration of alcohol use.

Successfully treatment of intercourse anejaculation with psychosexual counseling: A very rare case of situational anejaculation specific to penetrative sex with the wife.

Situational anejaculation means that a man can ejaculate in some situations but not in others. Intercourse type of anejaculation means existence of ejaculation by masturbation, but not during sexual intercourse. In some cases, men may be able to ejaculate and attain orgasm with one partner but not with another. Performance anxiety, hostility toward the partner, dysfunctional psychosexual development, and unconscious desire to avoid pregnancy are the possible underlying conditions. We herein reported a case of wife-specific intercourse anejaculation succesfully treated with sexual therapy. According to our best knowledge, this is an important case study in literature about intercourse type of situational anejaculation specific to the patient's wife that was treated with psychosexual counseling. The authors conclude that this clinical course of situational intercourse anejaculation suggests a psychological problem in these patients and sexual therapy is effective.

Comparison of nitric oxide level in Behçet's disease patients with or without psychiatric comorbidity.

Both Behçet's disease (BD) and major depressive disorder (MDD) are diseases associated with nitric oxide (NO). We hypothesized that the comorbidity of MDD affects the levels of NO in BD. In this study, we investigate whether there was a difference in NO levels among BD patients with accompanying MDD, BD patients with no depressive symptoms and healthy control group. There was a significant difference in NO levels among BD and control group (P < 0.05). Also, there was a significant difference between the BD group with MDD and BD group without psychiatric comorbidity in terms of NO levels (P < 0.05). This study is interesting as it demonstrates that accompanying psychiatric comorbidity puts an additional NO burden on the shoulders of BD patients.

Optical coherence tomography findings in conversion disorder: are there any differences in the etiopathogenesis of subtypes?

Abstract Background: Optical coherence tomography is a contactless and fast neuroimaging method. Previous Studies have observed thinning of the ganglion cell layer and inner plexiform layer in many neurodegenerative diseases. Objective: The aim of this study was to compare the layers of ganglion cell complex in conversion disorder. Methods: This study involved 50 conversion disorder patients and 50 healthy volunteers as the control. The parameters were measured and recorded automatically by a spectral optical coherence tomography device. Results: There was no difference in the retinal nerve fiber layers between the conversion disorder group and the control group (p > 0.05). The left and right choroid layer thickness acquired from three regions of the choroid layer was higher in patients compared with controls (p < 0.05). The ganglion cell layer and inner plexiform layer volumes were also significantly lower in the patient group (p < 0.05). Discussion: These ganglion cell layer and inner plexiform layer findings suggest that neurodegeneration occurs during the course of conversion disorder especially in subtype involved motor component. The choroid seems to be more related to the sensory component and it may be used to determine the active stage of the disease and to monitor inflammatory process like other inflammation markers used in systemic inflammatory diseases.

Mean platelet volume and neutrophil to lymphocyte ratio as parameters to indicate the severity of suicide attempt.

This study was designed to compare the complete blood count (CBC) values of 38 violent suicidal attempt (VSA) and 38 nonviolent suicidal attempt (NVSA) patients and 38 healthy controls, particularly mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR). MPV was found to be significantly higher (P = 0.000), and PLT was found to be significantly lower in the VSA group (P = 0.001). NLR was found to be significantly higher (P = 0.005) in the VSA group. The area under the receiver operating characteristic curve of MPV levels for VSA was 0.78 and 0.68 for NLR in the VSA group when compared with the NVSA group.

Complete blood count alterations due to the opioid use: what about the lymphocyte-related ratios, especially in monocyte to lymphocyte ratio and platelet to lymphocyte ratio?

This study was designed to compare the complete blood count values of opioid users (N = 61) and healthy subjects (N = 61), particularly monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR). PLR, MLR, and percentage of monocyte (MONO%) were significantly lower in opioid use disorder (OUD) group (P = 0.012, P = 0.005, P = 0.000). The area under the ROC curve of MLR and PLR levels for OUD was 0.349 and 0.368. MONO% correlated with substance use duration. Measurements like lymphocyte-related ratios and MONO% in opioid use can be important in substance monitoring, detection, and differentiation of acute and chronic conditions.
