Assessing the relationship between antipsychotic drug use and prolidase enzyme activity and oxidative stress in schizophrenia patients: a case-control study.

BACKGROUND: The relationship between proline, its association with oxidative stress, and its connection to schizophrenia is a subject that has not been sufficiently investigated. OBJECTIVE: The aim of this study is to evaluate the possible effects of atypical and combined (typical and atypical) antipsychotic use on serum prolidase enzyme activity (SPEA) and serum oxidative stress parameters, and to assess the relationship between SPEA and oxidative stress in patients with schizophrenia. METHODS: A total of 57 patients with schizophrenia, of which 34 were using atypical (AAPG) and 23 were using combined (typical and atypical) (CAPG) antipsychotic therapy, and 28 healthy volunteers (control group) were included in this case-control study. RESULTS: SPEA levels of AAPG and CAPG were significantly lower than that of control group ( P  = 0.003). The oxidative stress index (OSI) value of AAPG was significantly higher than the other two groups ( P  = 0.001). SPEA (<1860 U/l) and OSI (≥0.54) could discriminate schizophrenia patients with antipsychotic therapy from control groups ( P  = 0.001 and P  = 0.007, respectively). Lower SPEA levels were associated with antipsychotic use ( P  = 0.007). CONCLUSION: The SPEA values of patients with schizophrenia on antipsychotics were significantly lower compared to controls. OSI values were significantly higher in atypical antipsychotic recipients compared to those on combined antipsychotics and healthy controls.

A Preliminary Study on Investigation of Blood-Brain Barrier Damage Markers in Patients with Alcohol Use Disorder Before and After Therapy.

AIM: The use of alcohol affects the central nervous system and plays important roles in various neurological disorders through neurotoxicity resulting from blood-brain barrier (BBB) permeability. The BBB is regulated by tight junction proteins interacting closely with endothelial cells. This study evaluated the serum levels of proteins and spectrin degradation products associated with BBB damage in patients with alcohol use disorder. METHODS: This preliminary case-control study was conducted with 30 healthy volunteers and 26 alcohol use disorder patients. The serum levels of spectrin breakdown product 145 (SBDP145), spectrin breakdown product 150 (SBDP150), ubiquitin carboxy-terminal hydrolase L1 (UCHL1), ubiquitin ligase cullin-3 (ULC), occludin and claudin were measured with enzyme-linked immunosorbent assay. RESULTS: There was no significant difference between the levels of SBDP145, SBDP150, UCHL1, ULC, occludin and claudin before and after treatment in patients with alcohol use disorder. SBDP150 levels were significantly lower in patients than controls (P < 0.001). The area under the curve was 0.841 (0.733-0.949) with the 95% confidence interval for SPDP150. CONCLUSION: A decrease of the serum SBDP150 levels appears to be associated with alcohol use disorder. Future studies might clarify whether diminished serum SBDP150 levels are associated with BBB damage in patients with alcohol use disorder.

Evaluation of Changes in Peripheric Biomarkers Related to Blood Brain Barrier Damage in Patients with Schizophrenia and Their Correlation with Symptoms.

Objective: The aim of the study was to evaluate the levels of peripheric biomarkers that have been associated with blood brain barrier (BBB) damage in healthy controls and two groups of patients with schizophrenia, those who received typical-atypical antipsychotics and those who received only atypical antipsychotics. Additionally, we sought relationships between these biomarkers and schizophrenia symptoms. Methods: This study was conducted with the inclusion of 41 healthy volunteers and 75 patients with schizophrenia. The biomarkers measured to evaluate BBB injury were as follows: spectrin breakdown product 145 (SBDP145), spectrin breakdown product 150 (SBDP150), ubiquitin carboxy terminal hydrolase L1 (UCHL1), ubiquitin ligase cullin-3 (cullin), occludin and claudin, which were measured via ELISA. Symptoms of patients with schizophrenia were evaluated with the Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms, the Clinical Global Impression Scale (CGI), and the general assessment of functionality (GAF). Results: Compared to controls, SBDP145 (p = 0.022) and cullin (p = 0.046) levels were significantly higher in patients with schizophrenia receiving atypical antipsychotic treatment. SBDP150 levels were lower in the combination treatment group compared to the control group (p = 0.022). Claudin (p = 0.804), occludin (p = 0.058) and UCHL1 (p = 0.715) levels were similar among groups. In recipients of combination treatment, SBDP145 levels were found to be positively correlated with SAPS-total (r = 0.440, p = 0.036) and SAPS-delusions (r = 0.494, p = 0.017) scores. Conclusion: The relationships demonstrated in this study indicate that more comprehensive research is needed to understand whether BBB defects contribute to clinical characteristics in patients with schizophrenia.

Evolution of Telepsychiatry: Scientometric Analysis of Telepsychiatry Publications Between 1986 and 2019.

Introduction: Although telepsychiatry has a long history, medical literature lacks a scientometric study evaluating telepsychiatry publications. The purpose of this study was to perform a holistic analysis of telepsychiatry articles published between 1986 and 2019. Methods: We used the "telepsychiatry" keyword for our search and included all documents indexed in Web of Science (Clarivate Analytics, USA) Core Collection between 1986 and 2019, revealing a total of 1,020 articles, of which only 224 were open access. Results: The peak year for publication was 2015, with 96 articles. The United States ranked first with 601 documents followed by Australia and Canada. The University of California and University of Washington were the most productive institutions and, again, 8 of the 10 leading institutions were from the United States. The peak year for citations was 2019, with a total of 2,080 records. Discussion: We believe that systematic approaches are needed to reveal the positive and negative features of telepsychiatry practice, especially from countries where this method is widely utilized, to elucidate the need for telepsychiatry in other countries/regions and to determine how its use can be increased in regions with limited access to health care workers. Conclusion: Although scientific interest in telepsychiatry appears to have increased almost every year since 1986, it has been observed that this interest is still concentrated in certain countries, such as the United States, Australia, and Canada, indicating that telepsychiatry may not have gained use in other countries.

The Effect of Religious Belief and Forgiveness on Coping with Diabetes.

We aimed to investigate the relationship of religious beliefs and forgiveness in diabetic patients with various sociodemographic characteristics, emotional problems and glycaemic control. The study comprises 100 patients diagnosed with type 2 DM. We used a data collection form, the Scale of Forgiveness and Religiosity (SFR), Problem Areas in Diabetes Scale (PAID), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI) and the Audit of Diabetes-Dependent Quality of Life (ADDQoL). We also recorded blood glucose and HbA1c test results. A statistically significant relationship was determined only between the scores of the STAI-I and the religious belief scales (r = 0.198, p = 0.049). A statistically significant negative relationship was determined between the forgiveness scale points and the BDI (r = 0.326, p = 0.001), the STAI-II (r = 0.308, p = 0.002) and PAID (r = 0.313, p = 0.001) and a positive correlation with ADDQoL (r = 0.284, p = 0.004). To conclude, forgiveness by patient himself or others reduced the emotional problems which were experienced related to diabetes by reducing stress levels and could increase quality of life.

Preoperative anxiety may increase postcesarean delivery pain and analgesic consumption.

BACKGROUND: The aim of this study was to reveal the relationship between high level of prenatal anxiety and postoperative pain and/or analgesic consumption in women undergoing elective cesarean delivery under spinal anesthesia. METHODS: Eighty women, aged between 18-45 years with minimum 37 week- gestation and received spinal anesthesia during elective cesarean delivery, were included into this observational cohort study. Prenatal anxiety was measured with state anxiety inventory, trait anxiety inventory and somatosensory amplification scale. Visual Analogue Scale (VAS) was used to quantify postoperative pain. Amount of analgesic consumed was recorded at 6th, 12th and 18th postoperative hours. RESULTS: State Anxiety Score was above the threshold level (>45) in 18 women (22.5%). No difference was found between women with and without high state anxiety scores except for significantly higher BMI values in high-score group (P=0.07). In multivariate analysis, high BMI at pregnancy (OR: 1.2, 95% CI; 1.0-1.5, P=0.02) and high State Anxiety Score (OR: 1.1, 95% CI; 1.0-1.2, P=0.01) emerged as independent predictors of higher mean pain scores (VAS >4 cm) within 18 hours after cesarean delivery. Also, high State Anxiety Score was found to be independently associated with higher pethidine consumption after cesarean delivery (OR: 1.1, 95% CI; 1.0-1.2, P=0.006). CONCLUSIONS: State anxiety has a negative effect on postcesarean pain whereas trait anxiety does not seem to produce such effect. The effect seems to be more profound in overweight women. Detection of anxiety level before elective cesarean delivery and therapeutic approach to pregnant women may be useful for postoperative pain control.

Dream anxiety in renal transplant recipients.

OBJECTIVE: Although low quality of sleep has been reported in kidney transplant patients with functioning allografts, there are no previous studies investigating the dreams of these patients. We aimed to investigate the differences in dream anxiety level between renal transplant patients and healthy control subjects. We also planned to compare depression and anxiety symptoms, sleep quality and sleepiness level between these two groups. METHODS: Twenty-two living-donor renal transplant recipients followed at an outpatient nephrology clinic and 22 healthy controls were enrolled in this observational cross-sectional study. Sociodemographic Data Collection Form, and the Van Dream Anxiety Scale (VDAS), the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), Beck Depression and Anxiety Inventories were used for the assessment of the necessary features. Hemoglobin (Hb), blood urea nitrogen (BUN), creatinine (Cr) and glucose levels were measured. RESULTS: There were no significant differences between the groups in terms of dream anxiety (p = 0.45), depression (p = 0.76), sleep quality (p = 0.8), insomnia severity (p = 0.08) and Hb (p = 0.11) and glucose levels (p = 0.14). Although, BUN (p = 0.00) and creatinine (p = 0.00) levels differed significantly between the two groups, both parameters were found to be within their normal range. CONCLUSIONS: In our study, chronic renal failure patients with a successful kidney transplant were found to be able to completely return to normal in terms of metabolic parameters, sleep quality and mood. Similar levels of dream anxiety are also consistent with these findings.

Abnormal sexual behavior during sleep in temporal lobe epilepsy: a case report.

Herein, we describe a case who presented with abnormal sexual behaviour during sleep. Video-electroencephalography monitoring during sleep revealed an abnormality suggesting an epileptic basis. The patient was successfully treated with carbamazepin. The psychiatric symptoms that were thought to be related to abnormal sexual behaviours were controlled with antipsychotic treatment. Our findings strongly emphasize the fact that efforts should be spent to increase awareness of seizure activity at night, which can be misinterpreted as benign parasomnias. Such a misinterpretation may have serious consequences, such as insufficient seizure control, progressive personality changes, and cognitive impairment.
