Backround: Implant removal (IR) surgery is one of the most frequent procedures in orthopedic practice. Many of the IR surgeries result from patient request rather than a medical necessity. The purpose of the study was to investigate the association between the level of anxiety, type of temperament and psychopathological status, and the willingness to receive IR surgery in asymptomatic or mildly symptomatic patients. We also aimed to compare pre- and postoperative pain scores and document the complication rates after IR surgery., Methods: The patients who received tibia intramedullary nailing after tibia diaphyseal fracture with a minimum of 18 months follow-up were included in the study. A total of 246 asymptomatic or mildly symptomatic patients were evaluated, and all patients received detailed oral and written information about the risks of IR surgery. The patients who wished to receive IR surgery were called Group 1 (N = 104), and the patients who did not wish to have surgery were called Group 2 (N = 146). All patients were referred to a psychologist to complete the Beck anxiety inventory (BAI), Symptom checklist-90-R (SCL-R-90), and the Temperament Evaluation of Memphis, Pisa, and San Diego Autoquestionnaire (TEMPS-A)., Results: The mean age of the patients was 32.31 ± 9.56. One hundred thirteen (45.9%) of the patients were male, and 133 were female (54%). Mean BAI and SCL-90-R were higher in Group 1 than Group 2 (P = 0.001). Anxious and irritable temperament was higher in Group 1 (P = 0.045 and P = 0.035 respectively), and non-dominant and hyperthymic temperament was higher in Group 2 (P = 0.02 and P = 0.04 respectively)., Conclusions: The level of anxiety and type of temperament is associated with the willingness to receive implant removal surgery in asymptomatic or mildly symptomatic patients. Measures to reduce anxiety levels may reduce the rate of unnecessary implant removal surgeries, associated patient care costs, and potential complications., Competing Interests: Declaration of competing interest The all authors have no conflicts of interest to disclose. The informed consent from the all participants were obtained., (Copyright © 2021 The Japanese Orthopaedic Association. Published by Elsevier B.V. All rights reserved.)

The prevalence of metabolic syndrome (MetS) in schizophrenia patients is increasing worldwide. The aim of the current study was to examine the progress of MetS in a schizophrenia cohort we had previously investigated and determine the role of various related factors, including sociodemographic and clinical variables, nutritional status and physical activity. Of the 319 patients investigated in the first study, 149 patients agreed to be included in the follow-up. Physical measurements and laboratory tests were performed in addition to evaluations with the Positive and Negative Syndrome Scale, Udvalg for Kliniske Undersogelser Side Effects Scale, International Physical Activity Questionnaire, 24 h dietary recall method and Nutrition Information Systems Package Program. According to the ATPIII, ATPIIIA and IDF criteria, the MetS prevalences had increased from 35.6 to 44.3%, 38.9 to 53% and 43.6 to 55.7%, respectively. Patients with MetS had a shorter period of hospitalization and a higher UKU total side effects score, and most of them were married or divorced/widowed. Patients with MetS also had a higher daily consumption of added sugar, cholesterol, polyunsaturated fatty acids and omega 3 fatty acid, and the daily added sugar intake was found to be related to the increase in MetS. Unexpectedly, the physical activity level was not found to significantly differ in the patients with and without MetS. In conclusion, the MetS prevalence was found to be increased among schizophrenia patients over time, and the increase in the young age group was particularly striking. Among all of the factors investigated, nutritional status was found to play a major role in this increased prevalence.

Objective: Current drug treatments for schizophrenia are only partially effective and combination/augmentation strategies are commonly used. Nitric Oxide (NO) may play a role in the pathophysiology of schizophrenia. L-arginine is the precursor of NO. In this study, we aimed to investigate whether L-arginine add-on to current medication might improve positive, negative, and depressive symptoms in schizophrenia/ schizoaffective disorder patients in partial remission., Method: The study was designed as a randomized, double-blind, placebo-controlled, crossover study of L-arginine 3 g b.i.d. as an add-on treatment to the patients' usual medication. Twelve patients diagnosed with schizophrenia/schizoaffective disorder were included. The duration of the treatment was 3 weeks, with a wash-out period of 7 days before alternation for the second arm. Psychopathology was assessed with the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS), and the Clinical Global Impression (CGI) scales. The study was supported by Hacettepe University Scientific Research and Development Office (Project No: 011D0110101013) (Clinical Trials.gov Identifier: NCT02398279)., Results: Our analyses revealed that L-arginine 6 g/day add-on to usual treatment was not superior to placebo for positive, negative, and depressive symptoms associated with schizophrenia as assessed with PANSS, CDSS and CGI scales., Conclusion: In our study, L-arginine did not seem to have an effect on schizophrenia symptoms. Studies with a larger sample size, with higher doses of L-arginine, and with a longer duration are needed for a definite conclusion.

Clozapine use is associated with leukopenia and more rarely agranulocytosis, which may be lethal. The drug and its metabolites are proposed to interact with the multidrug resistance transporter (ABCB1/MDR1) gene product, P-glycoprotein (P-gp). Among various P-glycoprotein genetic polymorphisms, nucleotide changes in exons 26 (C3435T), 21 (G2677T), and 12 (C1236T) have been implicated for changes in pharmacokinetics and pharmacodynamics of many substrate drugs. In this study, we aimed to investigate the association between these specific ABCB1 polymorphisms and clozapine-associated agranulocytosis (CAA). Ten patients with a history of CAA and 91 control patients without a history of CAA, despite 10 years of continuous clozapine use, were included. Patient recruitment and blood sample collection were conducted at the Hacettepe University Faculty of Medicine, Department of Psychiatry, in collaboration with the members of the Schizophrenia and Other Psychotic Disorders Section of the Psychiatric Association of Turkey, working in various psychiatry clinics. After DNA extraction from peripheral blood lymphocytes, genotyping was performed using polymerase chain reaction and endonuclease digestion. Patients with CAA had shorter duration of clozapine use but did not show any significant difference in other clinical, sociodemographic characteristics and in genotypic or allelic distributions of ABCB1 variants and haplotypes compared with control patients. Among the 10 patients with CAA, none carried the ABCB1 all-variant haplotype (TT-TT-TT), whereas the frequency of this haplotype was approximately 12% among the controls. Larger sample size studies and thorough genetic analyses may reveal both genetic risk and protective factors for this serious adverse event.
