Homocysteine, hopelessness, rumination, affective temperaments, and clinical course in patients with bipolar disorder-1.

PURPOSE: This study aimed to explore the associations between homocysteine, rumination, affective temperaments, clinical features, and hopelessness in bipolar disorder-1 (BD-1). MATERIALS AND METHODS: In total, 57 euthymic patients with BD-1 and 57 healthy controls were included. The Beck Hopelessness Scale (BHS), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), and Ruminative Responses Scale Short Form (RRS-SF) were administered. Homocysteine, folate, and vitamin B12 levels were measured. RESULTS: The BHS total (p = 0.047), TEMPS-A irritable (p = 0.007), and TEMPS-A cyclothymic (p= 0.001) scores were significantly higher than the control group in the BD-1 group. Hyperhomocysteinemia (HHcy) was found in 33.3% of the patients (n = 19). In the HHcy group, age of onset of disease (p = 0.020) was significantly lower than the non-HHcy group in patients. Previous suicide attempt number was significantly correlated with scores of reflective pondering, brooding, and global rumination in BD-1 (p Ë‚ 0.05). Except for hyperthymic temperament, all types of affective temperaments were correlated with the scores of RRS-SF brooding (p Ë‚ 0.05) in the BD-1 group. The RRS-SF brooding scores significantly correlated with the BHS total scores (r = 0.263, p < 0.05); the TEMPS-A hyperthymic (ß = -0.351, p = 0.001) and TEMPS-A irritable (ß = 0.536, p < 0.001) scores significantly predicted the BHS total scores in the BD-1 group. CONCLUSIONS: The findings may lead clinical efforts and future clinical trials to explore and intervene in related sources and presentations of BD-1's adverse consequences.

Complementary integration of organic electrochemical transistors for front-end amplifier circuits of flexible neural implants.

The ability to amplify, translate, and process small ionic potential fluctuations of neural processes directly at the recording site is essential to improve the performance of neural implants. Organic front-end analog electronics are ideal for this application, allowing for minimally invasive amplifiers owing to their tissue-like mechanical properties. Here, we demonstrate fully organic complementary circuits by pairing depletion- and enhancement-mode p- and n-type organic electrochemical transistors (OECTs). With precise geometry tuning and a vertical device architecture, we achieve overlapping output characteristics and integrate them into amplifiers with single neuronal dimensions (20 micrometers). Amplifiers with combined p- and n-OECTs result in voltage-to-voltage amplification with a gain of >30 decibels. We also leverage depletion and enhancement-mode p-OECTs with matching characteristics to demonstrate a differential recording capability with high common mode rejection rate (>60 decibels). Integrating OECT-based front-end amplifiers into a flexible shank form factor enables single-neuron recording in the mouse cortex with on-site filtering and amplification.

The Effects of Hypocapnia and Hypercapnia on Intraoperative Bleeding, Surgical Field Quality, and Surgeon Satisfaction Level in Septorhinoplasty: A Prospective Randomized Clinical Study.

BACKGROUND: Septorhinoplasty (SRP) is one of the most commonly performed procedures in the world for functional and aesthetic purposes. The present study was aimed to compare the effects of hypocapnia and hypercapnia regarding the total amount of intraoperative bleeding, surgical field quality, and surgeon satisfaction level. METHODS: In this randomized prospective clinical study, eighty patients with American Society of Anesthesiologists I-II and were 18-45 years old scheduled for septorhinoplasty were randomly allocated to group hypocapnia [end-tidal carbon dioxide (EtCO2) 30 ± 2 mmHg] and group hypercapnia (EtCO2 40 ± 2 mmHg). We evaluated the total amount of intraoperative bleeding, the surgical field quality, surgeon satisfaction level, hemodynamics and peri- and postoperative adverse events. RESULTS: Group hypocapnia significantly reduced the total amount of intraoperative bleeding (p < 0.001). The surgical field quality and surgeon satisfaction level in group hypocapnia were significantly better than group hypercapnia (p < 0.001). EtCO2 levels of group hypocapnia were significantly lower than group hypercapnia at all time points (p < 0.001 for all time points). There were no significant differences between the groups in terms of heart rate and mean arterial pressure at all time points. There were no significant differences between the groups in terms of adverse events CONCLUSIONS: The results of this double-blind randomized clinical trial showed that reducing the amount of intraoperative bleeding for patients with hypocapnia undergoing SRP through known methods (e.g., reverse Trendelenburg head-up position, positive end-expiratory pressure limiting, controlled hypotension, and use of topical vasoconstrictors, corticosteroids, and tranexamic acid) would improve the quality of the surgical field and raise the surgeon satisfaction level.

Temporal tendency, seasonality and relationship with climatic factors of Crimean-Congo Hemorrhagic Fever cases (East of Turkey: 2012-2021).

Crimean-Congo Hemorrhagic Fever continues to be an important public health problem by expanding its borders. To evaluate the temporal trend, seasonality, and relationship with the climatic factors of Crimean-Congo Hemorrhagic Fever. Study data included cases treated in two different tertiary healthcare institutions between 2012 and 2021. The demographic characteristics of the cases and the dates of admission to the hospital were determined, and they were matched with the average of the measurements (temperature, cumulative precipitation, relative humidity, wind speed) of two different meteorology stations in the study area. By calculating the crude incidence rates, the trend in years was investigated. Estimates were created by removing the incidence rates, seasonality, and trend components using the additive decomposition technique. The temporal relationship between incidence rates and climatic factors was evaluated with the help of the Autoregressive Distributed Lag Bound Test. Toda Yamamoto test was used for causality verification. The mean age of the cases (n = 974) included in the study was 47.6 ± 17.7 years, and the majority (57.3%) were in the group above 45 years of age. 56.6% of the cases were male and there was a male predominance in all age groups. Incidence rates ranged from 5.5 to 23.1/100,000 over the ten-year period and there was a significant upward trend (R2 = 0.691, p = 0.003). Cases of Crimean-Congo Hemorrhagic Fever that started in March, peaked in July and ended in October, showed a clear seasonality. A cointegration relationship was observed between case incidence rates and air temperature, cumulative precipitation, and relative humidity (p < 0.05 for all). Climatic factors can only indirectly affect the occurrence of Crimean-Congo Hemorrhagic Fever cases. However, climatic conditions that become progressively more favorable for vector ticks lead to the spread of the disease. The control measures to be taken should be prepared by considering the changing climatic conditions and prioritizing the risk groups. There is a need for information and awareness-raising studies about climate change and the growing dangers associated with it, also outside of endemic regions.

Push and Pull Factors of Why Medical Students Want to Leave Türkiye: A Countrywide Multicenter Study.

Phenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Türkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Türkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Türkiye in 2022. Besides participants' migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Türkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22-1.54) times more likely to emigrate. The push factor that was related to emigration intention was the "working conditions in the country" (OR: 1.89, 95% CI: 1.56-2.28) whereas the "social environment/lifestyle abroad" was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45-2.06). In addition, the quality problem in medical schools also had a significant impact on students' decisions (OR: 2.20, 95% CI: 1.83-2.65). Insights: Although the percentage of those who want to emigrate "definitely" was at the same level as in the other developing countries, the tendency to migrate "permanently" was higher in Türkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians.

Evaluation the validity and reliability of the perceived medical school stress scale in Turkish medical students.

Medical education can be a challenging and stressful process. Additional stressors can make the medical education process even more complex and impair a student's attention and concentration. To the authors' knowledge, there is no valid and reliable scale to measure medical school stress in Turkish medical students. Therefore, this study aimed to determine the validity and reliability of the Perceived Medical School Stress (PMSS) Scale in Turkish medical students. The Perceived Medical School Stress Scale is a self-assessment tool developed to measure medical school-induced stress in medical students. It consists of 13 items divided into two subdimensions. Scale items are answered using a four-point (0-4) Likert system The total score that can be obtained from the PMSS ranges from 0 to 52, with higher scores indicating higher levels of perceived stress. First, the scale was applied as a pilot to 52 students by performing the scale's back-and-forth translation into Turkish. Then, the scale was applied to 612 volunteer medical students to ensure validity. Convergent validity and confirmatory factor analysis are used to assess the construct validity of a scale. Test-retest, item correlations, and Cronbach's alpha coefficients are used to evaluate the reliability of a scale. As a result of confirmatory factor analysis, the two-factor structure of the original scale was confirmed. The fit indices of the model obtained showed excellent fit. The Generalized Anxiety Disorder-7 (GAD-7) Scale was used for convergent validity. The GAD-7 is a self-assessment tool that measures the level of generalized anxiety. It is answered with a four-point Likert scale for the last two weeks. The score that can be obtained from the scale is between 0-21. A score of ten or more indicates possible anxiety disorder. The students' mean perceived medical school stress score was 39.80±8.09, and their GAD-7 score was 11.0±5.5. A significant positive relationship was found between the total scores of the scales (r = .48, P < .001). The Cronbach's alpha value of the scale was .81, and test-retest reliability was significant for all scale items (P < .001 for all). No item was deleted according to Cronbach's alpha values and item-total correlations. There was no significant relationship between Turkish version of the PMSS and GAD-7 scores and age, sex, income status, tobacco use, or exercise (P>.05). The Turkish version of the Perceived Medical School Stress Scale is a valid and reliable scale that can be used to investigate the medical school-specific stress of students.

Can pulse wave velocity measured preoperatively predict hypotension in hypertensive patients during anesthesia induction?

BACKGROUND: During the induction of general anesthesia, hemodynamic instability is a common occurrence in elderly hypertensive patients with increased arterial stiffness, which can cause undesirable complications. Pulse wave velocity (PWV) is an important indicator of arterial stiffness. OBJECTIVES: Investigate if preoperatively measured PWV is related to hemodynamic changes during induction of general anesthesia. DESIGN: Prospective, case control. SETTING: University hospital. PATIENTS AND METHODS: The study was carried out between December 2018 and December 2019 in patients 50 years or older scheduled for elective otolaryngology with endotracheal intubation and who had an American Society of Anesthesiologists (ASA) score of I or II. Patients diagnosed with hypertension (HT) or receiving treatment for hypertension for systolic blood pressure (SBP) ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg were compared with non-hypertensive patients (non-HT) of matching age and gender. MAIN OUTCOME MEASURES: PWV values between HT and non-HT patients and hypotension rates at the 30th second of induction, the 30th second of intubation, and the 90th second of intubation between the HT and non-HT groups. SAMPLE SIZE: 139 (95 with HT and 44 non-HT) RESULTS: PWV was higher in the HT group than in the non-HT group (P<.001). Hypotension at the 30th second of intubation in the HT group was significantly more frequent than in the non-HT group (P=.025). PWV was higher in hypotensive (n=62) than in non-hypotensive patients but the difference was statistically significant only for PWV measured at 30th second of intubation (n=77) (P=.018). CONCLUSIONS: The easily and non-invasively measured preoperative PWV may be an effective means of predicting hypotension during the induction of general anesthesia at the 30th second of intubation in HT patients. LIMITATIONS: Numbers of patients in the groups were not the same, and the study was not sufficiently powered to investigate the effect of hypertensive medications on PWV and arterial stiffness. CONFLICT OF INTEREST: None.

Epidemiological characteristics, seasonality, trends of dog bite injuries, and relationship with meteorological data.

INTRODUCTION AND OBJECTIVE: Animal bites are among the most critical in public health problems. Dogs are the leading cause of bite injuries. The study aimed to investigate the epidemiology and clinical features of dog bite cases admitted to an emergency department, as well as their temporal trends, seasonality, and tr relationship with meteorological data. MATERIAL AND METHODS: Study data comprised eight years (2012-2019) emergency room records of a tertiary center. Demographic characteristics of the cases, bite anatomical area, treatment applied, hospitalization, and death rates were determined. The incidence rates and distribution of meteorological data by years were examined using ANOVA and Kruskal Wallis tests. Seasonality and temporal trends were investigated for incidence rates using the additive decomposition technique. The temporal relationship of incidence rates with meteorological data was evaluated using the Autoregressive Distributed Delayed Boundary Test. Causality verification was perfoirmed using the Granger test. RESULTS: Dog bite cases consisted of 1,335 records of partients with a mean age of 26.6±0.2 years. Bite cases were most common in the 20-44 age group (44.7%), males (76.4%), and lower extremities (48.2%). The frequency of hospitalization was 4.1%. Annual incidence rates ranged from 52.7-49.9/100,000, with a non-significant increasing trend. The incidence of bites had two peaks, in June and August. A co-integration relationship was observed between incidence rates and air temperature and humidity levels (p<0.001). CONCLUSIONS: Effective implementation of prevention programmes is needed for high-risk demographic groups. In addition, a national monitoring and reporting system could evaluate the effectiveness of any prevention programme and reduce the incedence of dog bites.

The Effect of the Treatment of Severe Early Childhood Caries on Growth-Development and Quality of Life.

PURPOSE: Untreated early childhood caries (ECC) adversely affect children's quality of life. Our aim was to evaluate the effects of ECC on growth, development, and quality of life. DESIGN AND METHODS: A total of 95 children were divided into three groups: general anesthesia (GA) (n = 31), dental clinic (DC) (n = 31), and control (n = 33). ECOHIS was applied to the parents in the GA and DC groups during a pre-treatment period and also applied in the post-treatment in the first and sixth months. Height, weight, and BMI measurements of the children in the study groups were taken and recorded at the pre-treatment stage and in the post-treatment in the first and sixth months. However, for the control group, these measurements were made just at the baseline and in the sixth month. RESULTS: Upon the treatment of ECC, the total ECOHIS score significantly decreased (p < 0.001) in both groups in the following first month, whereas the scores of the children in the GA group reached a similar level to the DC group at the end of the sixth month. Following treatment, the weight and height of the children with ECC who initially had significantly lower BMI percentiles than the control group (p = 0.008) were observed to increase and, thus, they reached a similar BMI percentile value to the control group in the sixth month. CONCLUSIONS: The results of our study revealed that development and growth deficiencies in the children with ECC could be reversed rapidly by dental treatments and, thus, their quality of life would increase. The importance of treating ECC was revealed since treating ECC had positive effects both on the children's growth and development and on the quality of life of the children and their parents.

Role of TGF-ß1 and PDGF-B in Crimean-Congo hemorrhagic fever in Eastern Anatolia Region in Turkey.

BACKGROUND & OBJECTIVES: In this study, we aimed to investigate the relationship between serum TGF-ß1 and PDGF-B levels with the pathogenesis, clinical course and prognosis of adult Crimean-Congo hemorrhagic fever (CCHF) patients. METHODS: 50 adult patients and 30 healthy individuals as a control group were included in the study, who were followed up and treated with the diagnosis of CCHF at the Atatürk University Faculty of Medicine Infectious Diseases and Clinical Microbiology Clinic, between March 2017 and September 2019 in Eastern Anatolia Region in Turkey. Blood samples were taken from patients on the first day of their hospitalization and on the sixth day of their complaints. TGF-ß1 and serum PDGF-B levels were studied by ELISA method using commercial kits, from serum samples taken from CCHF patient group and individuals in healthy control group and stored at -80°C. RESULTS: While the serum TGF- ß1 levels of patients with CCHF were found to be significantly higher on the sixth day of their complaints compared to the first day of hospitalization (42.33 ± 15.42, 28.40 ± 7.06, p = 0.001, respectively), the serum PGDF-B levels were found to be significantly lower on the sixth day of their complaints compared to those measured on the day of hospitalization (62.14 ± 19.75, 93.96 ± 20.02, respectively, p = 0.001). INTERPRETATION & CONCLUSION: Serum TGF-ß1 levels are higher and PDGF-B levels are lower in CCHF patients with severe disease, indicating that serum TGF-ß1 and PDGF-B play an important role in the pathogenesis of CCHF.

The Effects of Laboratory Parameters on the Prognosis of COVID-19.

OBJECTIVE: While the coronavirus disease 2019 pandemic is an ongoing issue across the world, understanding the course of the disease is important for early diagnosis and treatment. We aimed, with this study, to determine the differences between laboratory parameters in different clinical pictures of coronavirus disease 2019. MATERIALS AND METHODS: The study included 443 patients who presented to Atatürk University Medical Faculty Hospital between March 15, 2020, and June 15, 2020, and were diagnosed with coronavirus disease 2019 upon a positive Real Time Polymerase Chain Reaction (RT-PCR) result. The hospitalized patients were divided into 4 groups based on their clinical status. The roles of these markers in determining the severity of coronavirus disease 2019 were statistically evaluated. RESULTS: A total of 443 patients with RT-PCR confirmation were included in the study. The mean age was 46.0 ± 19.1 years and 54.4% of the patients were male. According to the clinical classification, 16.3% of the cases were asymptomatic, 25.7% uncomplicated, 35.7% mild/moderate, and 22.3% severe. The first 3 most frequent symptoms were cough (21.3%), fever (17.7%), and fatigue (15.5%). Hypertension (36.1%) was the major comorbidity among the patients. During the follow-up of severe cases, 39.4% developed the need for intensive care. The overall mortality rate, on the other hand, was 4.7%. Regarding laboratory parameters, procalcitonin (PCT), serum ferritin, erythrocyte sedimentation rate, C-reactive protein, neutrophil count, D-dimer, troponin, and lactate dehydrogenase were at the highest level in the severe patient group while albumin, platelet, and lymphocyte count were found to be at the lowest level in the same group. A statistically significant difference was detected between the groups (P < .001). CONCLUSION: The increase in C-reactive protein, PCT, erythrocyte sedimentation rate, ferritin, troponin, D-dimer, lactate dehydrogenase, and neutrophil count and the decrease in albumin, platelet, and lymphocyte count are significant in the severe patient group; it has been concluded that they can be used to determine the severity of coronavirus disease 2019.

Comparison of Prostate Biopsy Using Multiparametric Magnetic Resonance Imaging in Patients with Prostate Biopsy Indications.

OBJECTIVE: This article aims to evaluate the efficacy of multiparametric magnetic resonance imaging before standard tru-cut biopsy in making prostate cancer diagnosis. MATERIALS AND METHODS: A total of 160 patients with prostate biopsy indications were prospectively evaluated between May 2017 and October 2018. Multiparametric magnetic resonance imaging was taken after obtaining a written informed consent from all patients. Cognitive transrectal ultrasound-guided biopsy was performed based on multiparametric magnetic resonance imaging results. Standard tru-cut biopsy was included to reduce false-negative rate. Statistical analysis was performed using the Statistical Package for Social Sciences version 20.0 software. RESULTS: The mean age of the patients was 65.94 ± 7.90 (48-84) years. Around 19.37% of the patients had a specificity in the digital rectal exam. The mean prostate-specific antigen value of the patients with adenocarcinoma was 42.1 ng/mL and it was 10.2 ng/mL in patients with benign prostate hyperplasia. It was observed that the prostate-specific antigen values in prostatic adenocarcinomas were significantly higher than those in benign prostate hyperplasia (P < .001). The results of multiparametric magnetic resonance imaging and the biopsy were 100% similar in terms of zones in patients with adenocarcinoma. All of the biopsy results of the patients who were evaluated to have normal prostate tissue in multiparametric magnetic resonance imaging were evaluated as benign prostate hyperplasia; on the other hand, 13.6% of PI-RADS 2 lesions, 14% of PI-RADS 3 lesions, 31.8% of PI-RADS 4 lesions, and 85.7% of PI-RADS 5 lesions were determined to be adenocarcinoma. It was observed that the prevalence of adenocarcinoma increased as the risk elevated in multiparametric magnetic resonance imaging (P < .001). CONCLUSION: Multiparametric magnetic resonance imaging evaluated by experienced radiologists may be instructive of urologists and reduce the need for unnecessary biopsies.

Usefulness of oxidative stress marker evaluation at admission to the intensive care unit in patients with COVID-19.

OBJECTIVE: Two critical processes in the coronavirus disease 2019 (COVID-19) pandemic involve assessing patients' intensive care needs and predicting disease progression during patients' intensive care unit (ICU) stay. We aimed to evaluate oxidative stress marker status at ICU admission and ICU discharge status in patients with COVID-19. METHODS: We included patients in a tertiary referral center ICU during June-December 2020. Scores of Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA), and clinical severity, radiologic scores, and healthy discharge status were noted. We collected peripheral blood samples at ICU admission to evaluate total antioxidants, total oxidants, catalase, and myeloperoxidase levels. RESULTS: Thirty-one (24 male, 7 female) patients were included. At ICU admission, patients' mean APACHE II score at ICU admission was 17.61 ± 8.9; the mean SOFA score was 6.29 ± 3.16. There was no significant relationship between clinical severity and oxidative stress (OS) markers nor between radiological imaging and COVID-19 data classification and OS levels. Differences in OS levels between patients with healthy and exitus discharge status were not significant. CONCLUSIONS: We found no significant relationship between oxidative stress marker status in patients with COVID-19 at ICU admission and patients' ICU discharge status.

The Efficacy of Intraoperative Freehand Erector Spinae Plane Block in Lumbar Spondylolisthesis: A Randomized Controlled Study.

STUDY DESIGN: Prospective randomized comparative (controlled) study. OBJECTIVE: Management of the severe postoperative back pain followed the major spinal surgeries remains a challenge. The search is going on to find simple, efficient, and reliable perioperative analgesia with low side effects. We aimed to investigate the efficacy of intraoperative freehand erector spinae plane block (ESBP) after spinal surgeries. SUMMARY OF BACKGROUND DATA: A few case reports and randomized controlled studies demonstrated the analgesic efficacy of ESPB in spinal surgeries. Up-to-date, no randomized controlled studies investigated the effectiveness of ESPB on spinal instrumentation surgeries. METHODS: We randomly divided 56 consecutive adult patients who underwent posterior spinal instrumentation and fusion for spondylolisthesis into two groups. The study (ESPB) group (n = 28) received intraoperative freehand bilateral ESPB with a 20-mL mixture solution of 0.25% bupivacaine and 1.0% lidocaine equally divided into all operating levels. In the control group (n = 28), 20 mL physiological saline was injected. Postoperatively, we ordered 1 g paracetamol thrice/day, besides patient-controlled analgesia pumps with morphine. We performed a postoperative evaluation with a visual analog scale (VAS), morphine consumption, ESPB-related adverse effects, and postoperative length of hospital stay (PLOS). RESULTS: Morphine consumption was significantly higher in the controls within the first postoperative 24-hour 44.75 ±â€Š12.3 mg versus 33.75 ±â€Š6.81 mg in the ESPB participants (P < 0.001). Except for postoperative 24th-hour VAS (P = 0.127), all postoperative VAS scores recorded at all time-points were significantly higher in the controls (P < 0.05). In control individuals, the first analgesic demand time was shorter, and PLOS was longer (P < 0.001). Patient satisfaction was significantly higher in the ESPB group. We observed no significant difference regarding postoperative complications. CONCLUSION: Intraoperative ESPB as a part of multimodal analgesia was effective. For posterior instrumented patients with spondylolisthesis, it can relieve postoperative backache and reduce opioid consumption.Level of Evidence: 1.

Questionnaire-guided evaluation of the effectiveness of long-term intravesical 0.2% chondroitin sulfate therapy in interstitial cystitis.

INTRODUCTION AND HYPOTHESIS: To investigate the long-term feasibility, safety and effectiveness of intravesical chondroitin sulfate therapy in patients with one or more forms of chronic cystitis. METHODS: The study included 62 female patients with interstitial cystitis/painful bladder syndrome (IC/PBS) who received intravesical chondroitin sulfate (40 ml/80 mg) therapy between 2014 and 2018. A total of 15 doses of intravesical treatment were applied, once weekly in the first month and once monthly from the second month onward. A 3-day voiding diary, a visual analog scale (VAS), the O'Leary Sant Indexes (ICSI/ICPI), the Pelvic Pain and Urgency/Frequency Symptom (PPUFS) Scale and PPUF Bother scores were recorded and evaluated through prospective comparison before treatment and at the first month and first year. Patients were also assessed using the Global Response Assessment (GRA) at the end of the first month and first year to assess the effectiveness of responses to treatment. RESULTS: In the first month of treatment, 0.2% chondroitin sulfate was ineffective in 22.5% of patients, with mild improvement observed in 40.0% and moderate-good improvement in 37.0%. Evaluation at the end of the first year revealed mild improvement in 21.0% of patients and moderate-good improvement in 79.0%. Statistically significant improvements were observed in all scoring systems at 1 and 12 months compared with pre-treatment values (p < 0.001). CONCLUSION: Long-term intravesical chondroitin sulfate therapy is a safe and highly successful therapeutic modality that produces significant improvement in patients' quality of life and symptoms in the treatment of IC/PBS.

Comparison of ultrasound-guided transversus abdominis plane block, quadratus lumborum block, and caudal epidural block for perioperative analgesia in pediatric lower abdominal surgery

Background/aim: Despite different regional anesthesia techniques used to provide intraoperative and postoperative analgesia in pediatric patients, the analgesic effectiveness of peripheral nerve blockades with minimal side effect profiles have not yet been fully determined. We aimed to compare the efficacy of ultrasound-guided transversus abdominis plane (TAP) block, quadratus lumborum (QL) block, and caudal epidural block on perioperative analgesia in pediatric patients aged between 6 months and 14 years who underwent elective unilateral lower abdominal wall surgery. Materials and methods: Ninety-four patients classified under the American Society of Anesthesiologists physical status classification system as ASA I or ASA II were randomly divided into 3 equal groups to perform TAP, QL or Caudal epidural block using 0.25% of bupivacaine solution (0.5 ml kg−1). Results: Postoperative analgesic consumption was highest in the TAP block group (P < 0.05). In the QL block group, Pediatric Objective Pain Scale (POAS) scores were statistically significantly lower after 2 and 4 h (P < 0.05). The length of hospital stay was significantly longer in the caudal block group than the QL block group (P < 0.05). Conclusion: We suggest that analgesia with ultrasound-guided QL block should be considered as an option for perioperative analgesia in pediatric patients undergoing lower abdominal surgery if the expertise and equipment are available.

The relationship with clinical course and prognosis of serum endothelin-1, angiopoietin-2, and tie-2 levels in Crimean-Congo hemorrhagic fever

Background/aim: Crimean-Congo hemorrhagic fever (CCHF) is a serious illness characterized by fever and hemorrhage. Endothelin-1 (ET-1), angiopoietin-2 (Ang-2), and endothelial cell-specific receptor tyrosine kinase (Tie-2) are believed to be important markers of the pathogenesis, clinical course, and prognosis of the disease. The aim of this study was to determine ET-1, Ang-2, and Tie-2 levels in adults with CCHF and investigate the associations between these markers and pathogenesis and disease course. Materials and methods: Sixty CCHF patients were included in the study. The patients were classified according to disease severity criteria and Ang-2, Tie-2, and ET-1 levels were compared. Results: Mean serum ET-1 level was 36.62 ± 27.99 pg/mL in the patient group and 3.70 ± 4.71 pg/mL in the control group (P = 0.001). Mean serum Ang-2 levels were 2511.18 ± 1018.64 pg/mL in the patient group and 3570.76 ± 209.52 pg/mL in the control group (P = 0.001). Mean serum Tie-2 levels were 7.35 ± 7.75 ng/mL in the patient group and 0.67 ± 1.26 ng/mL in the control group (P = 0.001). Conclusion: Elevated ET-1 and Tie-2 levels were associated with more severe disease course, while Ang-2 level was negatively correlated with severity in adult CCHF patients. ET-1, Tie-2, and Ang-2 levels are important prognostic parameters in CCHF and may contribute significantly to treatment and follow-up.

Assessing the Impact of Early Childhood Caries on the Development of First Permanent Molar Decays.

Aim: The aim of this study was to evaluate whether the treated and untreated severe early childhood caries (ECC) in children would make any impact on the Permanent First Molar (PFM) decays. Materials and Methods: Our descriptive epidemiological study was conducted in Ataturk University, Faculty of Dentistry, Department of Pediatric Dentistry/Erzurum-Turkey, between 2011 and 2017. We included a total of 90 children (44 girls, 46 boys), and divided them into 3 equal groups. They were 6-9 years old with a mean age of 7.38 ± 0.89. Group 1 consisted of the patients who had previously been treated under GA, Group 2 included the patients with untreated ECC and with no previous dental treatment, and Group 3 consisted of the patients who had been periodically treated in normal clinical settings. Each patient was processed through; dmft scoring and PFM caries evaluation process in accordance with International Caries Detection and Assessment System (ICDAS), respectively. The obtained data was analyzed with SPSS v20.0. And also, we used One-way ANOVA, Kruskal-Wallis and Mann Whitney U tests. Results: In accordance with ICDAS, we found that Group 3 had the highest mean number of PFMs (2 ± 1.43) and Group 2 had the lowest (1.43 ± 1.45). In Group 2, the number of ICDAS-determined carious PFMs were significantly lower than the other groups (p < 0.05). However, ICDAS score 6 was 0 in Group 1, while it was determined higher as 4.2% in Group 2. Conclusion: In respect to our research outcomes, which revealed that regardless of treated or not severe ECC had a significant impact on the PFMs, we strongly recommend that the parent of the children experiencing ECC should be informed about the risk of future caries in PFMs.

Evaluation of the Burden of Care and the Quality of Life in the Parents of Turkish Children with Familial Mediterranean Fever.

PURPOSE: This study aimed to determine the burden of care and the quality of life in caregivers of children with FMF. DESIGN AND METHODS: A cross-sectional study was conducted. Caregivers of the 109 children with FMF followed by a pediatric nephrology department were invited to join the study. Besides demographic information, the Zarit Care Burden Scale (ZCBS) and the World Health Organization Quality of Life Questionnaire-Short Form (WHOQOL-BREF) were used to collect data. Results for 90 patients were analyzed. RESULTS: The mean (±SD) ZCBS score of the caregivers was 44.78 ±â€¯13.55. Care burden of the caregivers according to the ZCBS was categorized as; 61.1% (n = 55) mild, 25.6% (n = 23) moderate, and 13.3% (n = 12) severe. Although single caregivers were perceived as having a relatively higher burden than those who were married (80% and 36%), this difference was not significant. There were no statistically significant differences between ZCBS categories concerning caregivers' gender, educational status, and having comorbidities (p > 0.05). Also, there were no significant correlations between ZCBS and the WHOQOL-BREF domains (p > 0.05). CONCLUSION: This study showed that the quality of life of the caregivers of children with FMF was not adversely affected, but a significant number of caregivers perceived care burden in moderate severity. Attention should be paid to the needs of caregivers, and they should be provided with adequate social, economic, physical, and psychological support. PRACTICE IMPLICATION: Responsive strategies to support caregivers' should be taken as means of social, economic, physical, and psychological needs.

Survival after cardiopulmonary arrest in a tertiary care hospital in Turkey.

BACKGROUND: Despite significant improvements in the field of cardiopulmonary resuscitation (CPR) over the past 40 years, disparate survival rates are reported after in-hospital cardiac arrest (IHCA). Few studies have addressed the effect of comorbid conditions on survival after IHCA. OBJECTIVE: Examine IHCAs over a two-year period, determine survival rates, and assess the effects of comorbid diseases on survival after IHCA. DESIGN: Retrospective, cross-sectional study. SETTING: Tertiary care hospital in Turkey. PATIENTS AND METHODS: Patients who had an IHCA recorded in the data management system between 1 January 2016 and 31 December 2017 were evaluated using Utstein-style records for data collection. The Charlson Comorbidity Index (CCI) was scored retrospectively. MAIN OUTCOME MEASURES: Return of spontaneous circulation (ROSC), survival in the first 24 hours, survival longer than 24 hours, and survival up to 6 months after discharge, CCI score, gender, age, location of IHCA, and first documented heart rhythm. SAMPLE SIZE: 370 IHCA cases. RESULTS: Of 502 patient, 370 met inclusion criteria. The presence of shockable rhythm was low (15.7%). The CCI was ≤3 in 10% (n=37) of all patients. A CPR duration of ≥20 minutes was the most important risk factor for ROSC. CCI ≥6 reduced ROSC-achieved cases by 2.8-fold ( P=.036) and increased the mortality rate by 2.8 fold ( P=.041). IHCA was most frequent in intensive care units (60.3%, n=223). CONCLUSION: Assessing patients at risk in the hospital for comorbid conditions by CCI would be beneficial to prevent deaths related to IHCA. Close monitoring of patients with high CCI scores is advisable, as is making IHCA calls on time. LIMITATIONS: Retrospective, small sample size, and no evaluation of the neurological condition of the discharged patients. CONFLICT OF INTEREST: None.
