Rationale, aims and objectives: This study aims to assess fear, anxiety, anxiety sensitivity, burnout, and insomnia of healthcare workers (HCWs) during novel coronavirus-2019 (COVID-19) outbreak and to identify their relation to sociodemographic and clinical characteristics. Method: Totally 600 HCWs were included in this cross-sectional study. A Sociodemographic Data Form, Coronavirus Anxiety Scale (CAS), Fear of COVID-19 Scale (FCV-19S), Anxiety Sensitivity Index-3 (ASI-3), Maslach Burnout Inventory (MBI), and Insomnia Severity Index (ISI) were used. Results: Of participants, 364 were females and 236 were males with a mean age of 33.49±7.29 years. About 95.3% of HCWs had a fear of infecting their loved ones. Mean MBI and ISI scores were significantly higher among HCWs working in COVID-19 clinics and intensive care units (p=0,000; p=0,039). Mean CAS, FCV-19S, MBI, and ISI scores were significantly higher in women than men (p=0,000; p=0,000; p=0,027; p=0,005). Mean CAS and ISI scores were significantly higher among nurses (p=0,008; p=0,004), while mean ASI-3 of the other HCWs and MBI scores of physicians were significantly higher (p=0,009; p=0,000). Conclusion: The COVID-19 pandemic is a major health issue associated with psychiatric illnesses in HCW subgroups with distinct sociodemographic characteristics. It is of utmost importance to develop individualized preventive and therapeutic psychiatric services for HCWs.

Objective We aimed to compare the effectiveness of extended-release naltrexone (XR-NTX) implant and sublingual buprenorphine-naloxone (BUP-NX) in relapse prevention in opiate use disorder (OUD). Methods Medical records of 400 patients who were treated for OUD between 2016 and 2020 were retrospectively evaluated concerning sociodemographic and clinical characteristics and abstinence duration with either BUP-NX (192 patients) or XR-NTX (208 patients) as maintenance treatments. Results The median age of patients using BUP-NX was 25.00, and the median age of patients using XR-NTX was 25.50 (p = .785). The ratio of female patients in the BUP-NX group and the XR-NTX group was 7.3% (n = 14) and 6.7% (n = 14), respectively. A significantly higher abstinence time was observed in the BUP-NX group (median = 4 months) than in the XR-NTX group (median = 3 months) (p = .015). Liver function tests were within the normal ranges at the three time points, which were just before the beginning and in the first and third months of treatment. Conclusions These findings suggest that BUP-NX might be more effective than XR-NTX in preventing relapse in OUD and both drugs are safe for the liver. Prospective randomized studies are needed to replicate our results.

BACKGROUND AND OBJECTIVES Substance use and addictive disorders are among the most significant public health concerns, particularly during adolescence. The current study aims to investigate internet gaming disorder, social media addiction, and loneliness levels in adolescents and youths with substance use. Methods: The study group consisted of 93 adolescents and youths aged 15-24 who presented to the Alcohol and Substance Addiction Research and Application Center or the Child and Adolescent Mental Health and Diseases outpatient clinic for substance use. Ninety-one healthy volunteers who did not use substances during any period of their lives participated as a control group. The participants fulfilled the Social Media Addiction Scale (SMAS), Internet Gaming Disorder Scale - Short-Form (IGDS9-SF), UCLA Loneliness Scale (UCLA-LS), and Drug Use Disorders Identification Test - Extended (DUDIT-E). Results: The symptoms of internet gaming disorder were significantly lower in the patient group compared with the control group. Although it was not significant, social media addiction was higher in the patient group than in the control group. The experience of loneliness was significantly higher in the patient group than in the control group. A significant negative correlation was found between treatment motivation and loneliness. Conclusions: School guidance teachers should monitor children who do not have friends or are lonely and be aware of the potential for substance use because it can emerge as a method of coping with the feeling of loneliness among adolescents. In future studies, investigating comprehensive factors contributing to different addictive behaviors may help to clarify the co-occurrence.

Despite several alternatives for cellular iron influx, the only mechanism for cellular iron efflux is ferroportin mediated active transport. In cases of ferroportin dysfunction, iron accumulates in the cell and causes ferroptosis. Hepcidin suppresses ferroportin levels and inflammatory activation increases hepcidin production. Mild inflammation in schizophrenia and bipolar disorder may alter hepcidin and ferroportin.The study included a total of 137 patients aged 18-65 years, 57 diagnosed with schizophrenia and 80 with bipolar disorder, according to the DSM-IV diagnostic criteria, and a control group (HC) of 42 healthy individuals. Biochemical analyses, thyroid function tests, hemogram, serum iron level, iron-binding capacity, and ferritin levels were examined. Serum levels of hepcidin and ferroportin were measured with enzyme-linked immunosorbent assay (ELISA) method.A statistically significant difference was determined between the groups in terms of the serum ferroportin levels (F = 15.69, p 0.001). Post-hoc analyses showed that the schizophrenia group had higher ferroportin levels than in the bipolar group (p 0.001) and HCs (p 0.001). Hepcidin levels did not differ between the groups. Chlorpromazine equivalent doses of antipsychotics correlated with ferroportin levels (p = 0.024).Ferroportin levels were increased in the schizophrenia group, although iron and hepcidin levels were within normal ranges. Antipsychotics may alter the mechanisms which control ferroportin levels. Further studies are needed to examine the relationships between antipsychotics and iron metabolism for determination of causal relationship.

Genotype distribution of hepatitis C virus (HCV) can vary over the years between different patient groups and regions. The prevalence of intravenous drug users (IVDU) is known to increase in our country, yet there are a limited number of studies investigating the distribution of HCV genotypes in this group. These data are essential for monitorization of the changes in HCV epidemiology. The present study aimed to evaluate the five-year results of HCV genotyping among patients infected with HCV related to IVDU and unrelated to drug use. Plasma samples of 720 patients (HCV antibody, HCV RNA positive), which were sent to our laboratory for HCV genotyping between January 2014-March 2019 were analyzed. HCV RNA extraction from plasma samples was performed in the automated-extraction system of EZ1 advanced (Qiagen, Germany) using the EZ1 virus mini kit v2.0 (Qiagen, Germany). Amplicons were obtained by amplifying the 5'NCR and core gene region in the Rotorgene 6000 real-time PCR (Qiagen, Germany) device with the HCV RNA real-time quantitative 2.0 (NLM, Italy) kit. For the genotyping, a commercial line probe assay (LIPA) based on in vitro reverse hybridization GEN-C2.0 kit (NLM, Italy) which can distinguish 1, 2, 3, 4, 6 genotypes and 1a, 1b, 2a/c, 2b, 3a, 3b, 3c, 3k, 4a, 4b, 4c/d, 4e, 4f, 4h, 5a, 6a/b, 6g, 6f/q, 6m, 7a subtypes of HCV, based on variations in the 5'-NCR and core regions was used. HCV genotype distribution of 266 IVDU (93.2%: male; median age: 25 ± 6.82) and 454 non-drug users (51.3%: male; median age: 56.5 ± 16.06) were examined. In order of frequency in the group with IVDU; genotype 1a, 3a, 1b, 4c/d, 2b, 4, 3 were observed and genotype 1, 2a/c and mixed genotype (1+3a) were detected in one patient. In the group without IVDU, in order of frequency; genotype 1b, 1a, 3a, 1, 2a/c, 4 were observed and genotype 2b, 4c/d, 5a, 6a/b, 6 and mixed genotype (3+4) were detected in one patient. Genotypes 1a and 3a were significantly higher in the IVDU group (p0.00001, p0.00001), while 1b was significantly higher in patients without IVDU (p0.00001). Genotypes 1a and 3a were more common in young men (p0.00001, p= 0.000163), while 1b was higher in middleaged women (p0.00001). The incidence of genotypes 1b (p= 0.021) and 3a (p= 0.012) was higher in foreign nationals than the Turkish patients. When the HCV genotype distribution was examined by years, it was observed that the percentages of genotype 1b and 1a were decreasing, while the percentage of genotype 3a was increasing. As a result, in this study, HCV genotype distribution among IVDU was observed to be different from the general population without IVDU. It was found that genotypes 1a and 3a were more common in the IVDU group. As in the other regions of our country, genotype 1b was found most frequently in the general population. Genotype 3a increases significantly compared to years. In our study, the determination of genotypes existing in different parts of the world may be due to the foreign nationals living in our city and our region is a tourism center. It is also necessary to investigate whether there is an increase in IVDU over the years.

Introduction: Cerebral venous and sinus thrombosis (CVST) may lead to cerebral edema and increased intracranial pressure; besides, ischemic or hemorrhagic lesions may develop. Intracerebral hemorrhages occur in approximately one-third of CVST patients. We assessed and compared the findings of the cerebral hemorrhage (CH) group and the CVST group. Materials and Methods: In the VENOST study, medical records of 1,193 patients with CVST, aged over 18 years, were obtained from 35 national stroke centers. Demographic characteristics, clinical symptoms, signs at the admission, radiological findings, etiologic factors, acute and maintenance treatment, and outcome results were reported. The number of involved sinuses or veins, localizations of thrombus, and lesions on CT and MRI scans were recorded. Results: CH was detected in the brain imaging of 241 (21.1%) patients, as hemorrhagic infarction in 198 patients and intracerebral hemorrhage in 43 patients. Gynecologic causes comprised the largest percentage (41.7%) of etiology and risk factors in the CVST group. In the CH group, headache associated with other neurological symptoms was more frequent. These neurological symptoms were epileptic seizures (46.9%), nausea and/or vomiting (36.5%), altered consciousness (36.5%), and focal neurological deficits (33.6%). mRS was ≥3 in 23.1% of the patients in the CH group. Discussion and Conclusion: CVST, an important cause of stroke in the young, should be monitored closely if the patients have additional symptoms of headache, multiple sinus involvement, and CH. Older age and parenchymal lesion, either hemorrhagic infarction or intracerebral hemorrhage, imply poor outcome.

BACKGROUND To see the relationship of early admission parameters with the type of stroke and/or with the 30-days mortality from this disease. METHODS Stroke patients at their early hyperacute phase (n = 180) were enrolled in this study (156 ischemic strokes and 24 hemorrhagic strokes). Blood levels of C-reactive protein (CRP), testosterone, and estradiol were determined at admission, before any specific intervention. Patients' clinical data, including the above-mentioned laboratory parameters, were compared between the above two stroke types (in total and between sexes). RESULTS The mean age of the patients was 69.55 ± 12.03 years old (69.92 ± 11.94 years old in ischemic stroke and 67.12 ± 12.54 years old in hemorrhagic stroke). Serum estradiol levels of both males of ischemic stroke and females of hemorrhagic stroke patients were significantly higher than the females of the ischemic stroke. Serum CRP levels of both females and males of the hemorrhagic group were higher than their peers of the opposite group. Early admission serum CRP level ≥ 0.74 mg/dL in males helped predict hemorrhagic stroke while a serum estradiol level ≥ 14.07 ng/mL helped predict the same type of stroke in females. CONCLUSIONS Our study results show that simple early laboratory measures (such as CRP and estradiol) may help in the early phase management of stroke. Further studies are needed to confirm our findings.

Objective In this study, the aim was to evaluate the lower extremity muscle strength in patients with chronic venous insufficiency using an isokinetic dynamometer. Methods The study comprised a group of 36 lower extremities of 23 patients diagnosed with chronic venous insufficiency and a control group of 40 lower extremities of 20 patients who did not have chronic venous insufficiency. In the diagnosis and evaluation of chronic venous insufficiency, photoplethysmography was used to evaluate the venous return circulation time. Visual Analog Scale scoring was applied to define the level of pain of the patients. Muscle strength measurements were made in all the lower extremities by using an isokinetic dynamometer. Results A statistically significant difference was detected between the groups in terms of the muscle strength parameters in the ankle plantar flexion, and knee flexor and extensor muscles. However, no statistically significant difference was found between the groups in the ankle dorsiflexion muscle strength parameters. A significant difference was determined in the ratio of ankle dorsiflexion/plantar flexion muscle strength between the mild, moderate and severe venous insufficiency groups. A statistically considerable negative correlation was found between the Visual Analog Scale scores and the photoplethysmography results. According to the Visual Analog Scale results, as the degree of venous insufficiency increased, so did the level of pain. Conclusion Impaired lower extremity muscle strength was observed in chronic venous insufficiency patients. Although the current study was consistent with literature in respect of impaired calf muscle strength, this finding was also seen in the thigh muscles. Furthermore, we concluded that if venous insufficiency becomes more severe, impaired calf muscle strength becomes more evident.

Background Intravenous tissue plasminogen activator (IV tPA) was shown to be an effective treatment for acute ischemic stroke (AIS). According to stroke guidelines, there is no need to wait for the complete blood count (CBC) and coagulation test results before application of IV alteplase if there is no suspected coagulation disorder. In this study, a patient with AIS and thrombotic thrombocytopenic purpura (TTP) symptoms during thrombolytic treatment was presented. Case A 33-year-old male patient was admitted at the 2.5th hour of AIS symptoms onset with right hemiparesis and sensorimotor aphasia. Cranial computed tomography (CT) and diffusion magnetic resonance imaging did not reveal any abnormality. In his medical history, the patient did not have any contraindication for thrombolytic treatment. To avoid delays to thrombolytic therapy, blood samples were taken, and after that, IV bolus alteplase treatment was applied. During maintenance treatment, agitation and vomiting developed. The result of blood samples showed less than 26,000 mm3 platelet count and maintenance therapy was stopped. In control cranial CT, there was no hemorrhage. In the laboratory examination; anemia, low platelet count; increased indirect bilirubin, lactate dehydrogenase (LDH) levels were found, and fever was 38.4°C. Schistocytes were observed in peripheral blood smear and the patient was diagnosed as TTP. Conclusions Stroke guidelines recommend not to wait for the results of CBC and coagulation tests before IV tPA treatment in patients who do not have any history of coagulopathy disorder. If possible, before applying IV tPA we may wait for the results of coagulation and CBC tests, keeping in mind the diseaes with high mortality such as TTP.

The purpose of this study was to test the influence of custom-made mouth guards on strength and anaerobic performance of taekwondo athletes. The study included 21 (11 male and 10 female) trained subjects participating in taekwondo. Anaerobic power and anaerobic capacity, isokinetic quadriceps and hamstring strength, handgrip strength, isometric lower extremity and back strength, 20 m sprint time, squat and counter movement jumping height were measured in two randomized conditions: with or without custom-made (CM) mouth guards. No significant differences were observed between the two conditions (with or without CM mouth guards) in 20 m sprint time, jumping tests, handgrip strength, isometric leg or back strength. On the other hand, peak power and average power in Wingate Anaerobic Test and Hamstring Isokinetic Peak Torque significantly increased as a result of wearing mouth guard (P < 0.05). In conclusion, we can suggest that taekwondo athletes can use CM mouth guards without any negative effects on their strength and anaerobic performance.
