Performance of ChatGPT on Factual Knowledge Questions Regarding Clinical Pharmacy.

ChatGPT is a language model that was trained on a large dataset including medical literature. Several studies have described the performance of ChatGPT on medical exams. In this study, we examine its performance in answering factual knowledge questions regarding clinical pharmacy. Questions were obtained from a Dutch application that features multiple-choice questions to maintain a basic knowledge level for clinical pharmacists. In total, 264 clinical pharmacy-related questions were presented to ChatGPT and responses were evaluated for accuracy, concordance, quality of the substantiation, and reproducibility. Accuracy was defined as the correctness of the answer, and results were compared to the overall score by pharmacists over 2022. Responses were marked concordant if no contradictions were present. The quality of the substantiation was graded by two independent pharmacists using a 4-point scale. Reproducibility was established by presenting questions multiple times and on various days. ChatGPT yielded accurate responses for 79% of the questions, surpassing pharmacists' accuracy of 66%. Concordance was 95%, and the quality of the substantiation was deemed good or excellent for 73% of the questions. Reproducibility was consistently high, both within day and between days (>92%), as well as across different users. ChatGPT demonstrated a higher accuracy and reproducibility to factual knowledge questions related to clinical pharmacy practice than pharmacists. Consequently, we posit that ChatGPT could serve as a valuable resource to pharmacists. We hope the technology will further improve, which may lead to enhanced future performance.

Evaluation of the effect of 9.5/11.5-fr ureteral access sheath use on acute kidney injury with the myo-inositol oxygenase biomarker in patients undergoing retrograde intrarenal surgery: a prospective, randomized, and controlled study.

INTRODUCTION: We aimed to investigate whether a low intrarenal pressure provided by ureteral access sheath (UAS) use had a positive effect on the prevention of acute kidney injury through the evaluation of the myo-inositol oxygenase (MIOX). MATERIAL AND METHODS: The patients were divided into two groups according to whether a 9.5/11.5-Fr UAS was used during retrograde intrarenal surgery (RIRS): UAS group and non-UAS group. RIRS was performed under gravity irrigation and manual pumping was not used. For the measurement of MIOX, 5 cc blood samples were taken from the patients preoperatively and four hours postoperatively. RESULTS: Operation time and hospital stay were significantly longer in the UAS group. The mean preoperative and postoperative MIOX values were 0.77 ± 0.36 ng/ml and 0.74 ± 0.38 ng/ml, respectively, in the UAS group, and 0.74 ± 0.31 ng/ml and 0.83 ± 0.40 ng/ml, respectively, in the non-UAS group. The mean MIOX change was -0.29 ± 0.36 in the UAS group and 0.08 ± 0.44 in the non-UAS group, indicating no significant difference between the groups. CONCLUSION: Even if UAS is not used, significant acute kidney injury is not observed under gravity irrigation and therefore, if we avoid manual pumping, the intrarenal pressure remains low, thus potentially rendering the use of 9,5/11,5-Fr UAS unnecessary.

Poor performance of ChatGPT in clinical rule-guided dose interventions in hospitalized patients with renal dysfunction.

PURPOSE: Clinical decision support systems (CDSS) are used to identify drugs with potential need for dose modification in patients with renal impairment. ChatGPT holds the potential to be integrated in the electronic health record (EHR) system to give such dosing advices. In this study, we aim to evaluate the performance of ChatGPT in clinical rule-guided dose interventions in hospitalized patients with renal impairment. METHODS: This cross-sectional study was performed at Tergooi Medical Center, the Netherlands. CDSS alerts regarding renal dysfunction were collected from the electronic health record (EHR) during a 2-week period and were presented to ChatGPT and an expert panel. Alerts were presented with and without patient variables. To evaluate the performance, suggested medication interventions were compared. RESULTS: In total, 172 CDDS alerts were generated for 80 patients. Indecisive responses by ChatGPT to alerts were excluded. For alerts presented without patient variables, ChatGPT provided "correct and identical" responses to 19.9%, "correct and different" responses to 26.7%, and "incorrect responses to 53.4% of the alerts. For alerts including patient variables, ChatGPT provided "correct and identical" responses to 16.7%, "correct and different" responses to 16.0%, and "incorrect responses to 67.3% of the alerts. Accuracy was better for newer drugs such as direct oral anticoagulants. CONCLUSION: The performance of ChatGPT in clinical rule-guided dose interventions in hospitalized patients with renal dysfunction was poor. Based on these results, we conclude that ChatGPT, in its current state, is not appropriate for automatic integration into our EHR to handle CDSS alerts related to renal dysfunction.

The effect of kinesio taping on pain, respiratory function, and muscle strength after thoracotomy.

Background: This study aims to investigate the effectiveness of kinesio taping on pain, respiratory function, and respiratory muscle strength in patients after posterolateral thoracotomy. Methods: Between June 2019 and May 2020, a total of 88 patients (48 males, 40 females; mean age: 56.1±9.0 years; range, 28 to 69 years) following posterolateral thoracotomy were randomly allocated to the therapeutic kinesio taping group (n=44) or the control group (n=33). Kinesio taping was applied to the kinesio taping group for seven days. Pain, respiratory functions, respiratory muscle strength, amount of analgesic drug use, and quality of life were evaluated preoperatively, on postoperative Day 0, before tape application, postoperative Days 1, 2, and 7, and at postoperative first month. Results: There was no significant difference between the groups in terms of demographic and clinical characteristics. The results of respiratory functions and respiratory muscle strength were all improved in both groups, while there were more significant improvements in the kinesio taping group. There was a statistically significant difference in the mean Visual Analog Scale scores on postoperative Days 2 and 7 between the two groups. The amount of tramadol use of the patients in the kinesio taping group was significantly lower on postoperative Days 2 and 7 than in the control group. Conclusion: Kinesio taping is an effective method to reduce pain and improve respiratory function after posterolateral thoracotomy. Therefore, it is thought that kinesio taping should be applied as a part of the pulmonary rehabilitation program after thoracotomy.

A rare phenomenon, primary pulmonary smooth muscle tumor and its management.

Smooth muscle tumors of uncertain malignant potential, the borderline tumors arising from the smooth muscle cells, usually grow slowly and do not fulfill the diagnostic criteria of leiomyosarcoma and its variants, but may behave in a malignant manner. A 15-year-old female patient with an endobronchial mass in the left main bronchus on thoracic computed tomography underwent thoracotomy and tracheobronchoplasty with a wide and safe margin. Histopathological evaluation revealed a smooth muscle tumor of uncertain malignant potential. There were no complications related to the operation during the hospital stay. At six months of surgery, there were no symptoms or signs suggesting any recurrence in her follow-up. In conclusion, In conclusion, pulmonary leiomyomas may rarely present as an endobronchial mass and may mimic asthma by causing respiratory symptoms developing as attacks due to displacement of the mass within the lumen.

Is preoperative pulmonary rehabilitation effective in the postoperative period after lung resection?

Objective: Investigating the effects of the preoperative short term intensive pulmonary rehabilitation program applied for patients who have undergone lung resection by thoracotomy, on lung functions, complication rates and length of hospital stay during the postoperative period. Methods: A prospective randomized trial of sixty patients were enrolled who would undergo pulmonary resection by thoracotomy and were randomly divided in two groups. Intensive pulmonary rehabilitation was performed on these patients in the study group 3 hours a day throughout 7 days during the preoperative period. Groups were compared with respect to their spirometric pulmonary functions, respiratory parameters, blood gas parameters, complication rates and length of hospital stay. Results: Total incidence rate of complications in the patients from the control group significantly increased(p=0,028). When patients who underwent lobectomy and wedge resection were observed, length of hospital stay of those in the control group was seen to be statistically higher in comparison with the study group(p<0,05). Conclusion: We consider that it will be very beneficial to perform a short term and intensive pulmonary rehabilitation program on every patient possible who is planned to undergo thoracotomy and lobectomy or wedge resection treatment.

Carotid artery intima media thickness can predict the response to phosphodiesterase 5 inhibitors in patients with moderate erectile dysfunction.

Background: Increased carotid artery intima-media thickness (CIMT) has been shown to be associated with erectile dysfunction (ED), but studies evaluating the efficacy of CIMT in predicting drug response are lacking in the literature. Aim: We aimed to evaluate the efficacy of CIMT in predicting the response to phosphodiesterase-5 inhibitors (PDE5-I). Methods: A total of 274 subjects were divided into two groups: ED patients (n = 150) and controls (n = 124). The patients in the ED group were further divided into the subgroups of severe, moderate, mild-moderate, and mild ED. Blood tests, carotid ultrasonography, and the International Index of Erectile Function-5 (IIEF-5) diagnostic tool were applied to all subjects. Tadalafil was administered to each patient. The patients were re-evaluated using the IIEF-5 questionnaire after 2 months of treatment. According to their response to medication, the patients were evaluated as responders or nonresponders. Outcomes: Increased CIMT was significantly associated with the failure of PDE5-I therapy, especially in patients with moderate/mild-moderate ED. Results: Fasting blood glucose, body mass index, and CIMT were significantly higher in the ED group compared to the control group (P = .021, P = .006, and P < .001, respectively). The IIEF-5 score was significantly lower in the ED group (P < .001). CIMT was significantly correlated with the IIEF-5 score. When the total patient group was evaluated, the CIMT value of the responders was significantly lower than that of the nonresponders (P = .001). CIMT was significantly higher among the nonresponders with moderate/mild-moderate ED compared to the responders (P = .004 and .008, respectively), while there was no significant difference in CIMT between the responders and nonresponders with severe or mild ED. A receiver operating characteristic (ROC) analysis of CIMT was performed for discrimination between nonresponders and responders with moderate/mild-moderate ED. The area under the ROC curve was 0.801 (0.682-0.921) (P = .001), and the cutoff value was determined to be 0.825 mm, at which CIMT predicted the response to treatment with 65% sensitivity and 89% specificity. Clinical Implications: Using a validated CIMT cutoff value can help the physician inform the patient about the possibility of drug failure and avoid attempting second-line therapy too soon. Strengths and Limitations: There are three main limitations to our study. First, the number of participants was low. Second, ultrasound is a relatively subjective method, and third, all measurements were made by the same radiologist. Conclusion: CIMT can be used as a predictor of response to PDE5-I therapies in patients with moderate/mild-moderate ED.

The effect of anesthesia type on the outcomes of percutaneous nephrolithotomy in elderly males.

Objective: To compare the anaesthesia methods in percutaneous nephrolithotomy in terms of safety and effectiveness in elderly men.Methods: Elderly male patients who had undergone percutaneous nephrolithotomy were screened retrospectively and divided into 2 groups: percutaneous nephrolithotomy under combined spino-epidural anaesthesia (Group CSEA, n = 70) and percutaneous nephrolithotomy under general anaesthesia (Group GA, n = 114). Preoperative, perioperative and postoperative outcome measures were examined.Results: Between the two groups, there was no statistically significant difference in terms of stone burden, stone location, presence of the previous operation in the same kidney, presence of staghorn stones, mean American Society of Anesthesiologists scores and presence of abnormal kidney (p > 0.05). The mean duration time in the operation room and post-anaesthesia care unit (PACU) was statistically shorter in the Group CSEA (p < 0.01). There was no significant difference between the two groups in terms of Clavien Grade 1 and above complications (p > 0.05). Stone-free rates and success rates were similar in both groups (p = 0.133 and p = 0.273, respectively).Conclusion: The type of anaesthesia does not affect the success rate and complication rate of percutaneous nephrolithotomy in elderly male patients. Patients who underwent percutaneous nephrolithotomy under CSEA needed less analgesic injection during the postoperative period. CSEA can shorten the time a patient spends in the operating room and PACU, which provides more effective use of operation room working hours.

Combined spino-epidural anaesthesia (CSEA) can be safely administered in elderly men during PNL operation without affecting surgical success. CSEA patients less occupy the operating rooms. CSEA patients' postoperative period is more comfortable because of the less painful period.

The Effectiveness of Active External Warming of Patient Concurrently With Ice Application on the Incision Site on Post-Thoracotomy Pain and Analgesic Consumption.

The aim of study is to investigate the effects of active external warming of patient concurrently with application of ice to incision site on thoracotomy pain and analgesic consumption. The research is a quasi-experimental design with control and study groups. The study was conducted in 2018 and 2019. A total of 70 patients were included in the study: 35 in the control group and 35 in the study group. The mean verbal pain scale values were significantly lower in the intervention group (2.85 point) than in the control group (4.57 point; p < .001). Opioid consumption rate was high in control group patients (77.1% tramadol 30 mg; 45.7% morphine sulfate 5 mg) In contrast, the rate of opioid consumption was lower in patients in the intervention group (40% tramadol 30 mg; 17% morphine sulfate 5 mg). Active external warming and ice application on the incision area, could reduce the intensity of thoracotomy pain.

Comparison of serum Kim-1 and Miox levels in patients that underwent percutaneous nephrolithotomy and flexible ureterorenoscopy.

OBJECTIVE: Percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) are common surgical methods in the treatment of kidney stones. Possible effects on kidneys are an important factor in determining the surgical procedure and the surgical method. In our study, kidney injury molecule-1 (KIM-1) and myo-inositol oxygenase (MIOX) were used to compare acute kidney injury in patients that underwent PNL and RIRS. MATERIAL AND METHOD: Eighty patients aged 20-75, who underwent PNL or RIRS in our urology clinic between November 2018 and February 2020 were included in the study. In this prospective study, the demographic characteristics, stone size, operation time, preoperative and postoperative hemoglobin and biochemistry values of the patients were recorded. About 5 cc blood samples taken from the patients before the operation and at the fourth hour after the operation were centrifuged and kept at -80°C, and the KIM-1 and MIOX levels were measured in the biochemistry department. RESULTS: There was no difference between the groups in terms of demographic data; however, the operation time and length of hospital stay were significantly longer in the PNL group. The mean increase in MIOX was 10.583 ± 9.73 and 7.501 ± 16.46 ng/ml in the PNL and RIRS groups, respectively. Although there was a statistically significant increase in both groups, this increase was greater in the PNL group. A significant increase was observed only in the PNL group in the postoperative period (p = 0.003). DISCUSSION AND CONCLUSION: The findings of the study suggest that the PNL procedure causes more damage to the kidneys than RIRS.

Can atherogenic indices and the triglyceride-glucose index be used to predict erectile dysfunction?

Background: Atherosclerosis and insulin resistance play an important role in the development of erectile dysfunction (ED), and few studies have comprehensively evaluated more specific indicators like atherogenic indices and the triglyceride-glucose (TyG) index in the assessment of ED. Aim: This study aimed to reveal the role of atherogenic indices (atherogenic index of plasma [AIP], Castelli risk index-1/2 [CRI-1/2], and atherogenic coefficient [AC]) based on plasma lipid ratios, which have been used as more sensitive indicators of atherosclerosis in recent years, and the TyG index, a practical indicator of insulin resistance, in predicting vasculogenic ED. Methods: The study included a total of 199 patients who met the inclusion criteria and a total of 51 control subjects without ED complaints according to the International Index of Erectile Function (IIEF-5) scores (>21) between May 2021 and October 2022. For all participants, the demographic and biochemical parameters were evaluated, and atherogenic indices, namely CRI-1 (total cholesterol/high-density lipoprotein [HDL]), CRI-2 (LDL/HDL) AIP [log10(triglycerides/HDL)], and AC (non-HDL/HDL), as well as the TyG index [Ln {fasting triglycerides (mg/dL) × fasting glucose (mg/dL)/2}] were calculated. Outcomes: The TyG index, which is an indicator of insulin resistance, and atherogenic indices such as CRI-1, AIP, and AC were significantly associated with ED, and especially AIP and the TyG index seem to be more important in the evaluation of ED. Results: According to the univariate analysis, the patient group had significantly higher CRI-1 (5.3 ± 1.4 vs 4.7 ± 1.3; P = .005), AIP (0.31 ± 0.26 vs 0.13 ± 0.2; P < .001), AC (4.1 ± 1.4 vs 3.70 ± 1.2; P = .026), and TyG (9.16 ± 0.71 vs 8.77 ± 0.52; P < .001) values compared with the control group. In the correlation analysis, a significant negative correlation was found between the AIP and TyG index and the IIEF-5 scores (r2 = 0.120, P < .001 between AIP and IIEF-5; r2 = 0.091, P < .001 between TyG index and IIEF-5). The multivariate analysis revealed AIP and the TyG index as independent predictive factors for ED. Clinical Implications: The use of atherogenic indices and TyG index in daily urology practice can help physicians in the diagnosis and follow-up of ED. Strengths and Limitations: The lack of sex hormone-binding globulin and free testosterone levels represents a limitation of our study. Another limitation is that the severity of ED was determined using the IIEF-5 scores, rather than a more objective method, such as penile artery ultrasound. Conclusion: Atherogenic indices and the TyG index can be used as inexpensive and practical markers to predict the severity of arteriogenic ED.

Assessing the nitric oxide and asymmetric dimethylarginine levels in lifelong premature ejaculation: A prospective study / Evaluación de los niveles de óxido nítrico y dimetilarginina asimétrica en la eyaculación precoz de por vida, un estudio prospectivo

Objective: To evaluate nitric oxide (NO) and asymmetric dimethylarginine (ADMA) levels in men with premature ejaculation (PE), which is a common condition that adversely affects quality of life. Material and method: Of the 20–50-year old men presenting to the urology clinic, who were married or had regular sexual intercourse, 40 that were diagnosed with lifelong PE according to the Premature Ejaculation Diagnostic Tool (PEDT) and intravaginal ejaculation latency time (IELT) measured by a stopwatch were included in the study. The results of the PE group were compared to those of the control group formed with 40 healthy hospital personnel. Venous blood samples were centrifuged and stored at −80°C. The NO and ADMA values were compared between the individuals with and without PE. Results: There was no statistically significant difference between the groups in terms of age, body mass index (BMI), and The International Erectile Dysfunction Index-5 (IIEF-5) questionnaire scores. The NO and ADMA values were significantly lower in the PE group than in the control group (29.76±13.26μmol/L vs. 48.27±22.71μmol/L; p<0.001 and 1.01±0.49nmol/ml vs. 1.83±1.06nmol/ml; p<0.001, respectively). There was a significant correlation between IELT and NO levels (r=0.407, p=0.001). Conclusion: Our study can contribute to the explanation of the pathophysiology of PE having unclear etiology and treatment. Further studies on these molecules with larger case series are required for the diagnosis and treatment of PE. (AU)

Objetivo: Evaluar los niveles de óxido nítrico (NO) y dimetilarginina asimétrica en hombres con eyaculación precoz (EP), que es una afección común que afecta negativamente la calidad de vida. Material y método: De los hombres de 20 a 50 años que acudieron a la clínica de urología, que estaban casados o tenían relaciones sexuales regulares, se incluyeron en el estudio 40 que fueron diagnosticados con EP de por vida según la Herramienta de Diagnóstico de la Eyaculación Precoz y el tiempo de latencia de la eyaculación intravaginal medidos por un cronómetro. Se compararon los resultados del grupo de EP con los del grupo control formado por 40 personas sanas del hospital. Las muestras de sangre venosa se centrifugaron y almacenaron a −80°C. Se compararon los valores de NO y dimetilarginina asimétrica entre los individuos con y sin EP. Resultados: No hubo diferencias estadísticamente significativas entre los grupos en términos de edad, índice de masa corporal y puntajes del cuestionario International Erectile Dysfunction Index-5. Los valores de NO y dimetilarginina asimétrica fueron significativamente más bajos en el grupo de EP que en el grupo control (29,76±13,26 frente a 48,27±22,71μmol/l [p<0,001] y 1,01±0,49 frente a 1,83±1,06nmol/ml [p<0,001], respectivamente). Hubo una correlación significativa entre los niveles de tiempo de latencia de la eyaculación intravaginal y NO (r=0,407, p=0,001). Conclusión: Nuestro estudio puede contribuir a la explicación de la fisiopatología de la EP de etiología y tratamiento poco claros. Se requieren más estudios sobre estas moléculas con series de casos más grandes para el diagnóstico y tratamiento de la EP. (AU)

What are the independent prognostic factors in patients undergoing esophagectomy for esophageal cancer?

Background: This study aims to investigate the prognostic factors affecting survival in patients undergoing surgical treatment for esophageal cancer. Methods: A total of 50 patients (33 males, 17 females; mean age: 57.8±11.8 years; range, 28 to 80 years) who underwent esophagectomy for esophageal cancer in our clinic between January 2008 and March 2018 were retrospectively analyzed. Prognostic factors affecting survival were investigated. Data including age, sex, tumor size, histological and macroscopic type, tumor stage, T and N categories, the total number of resected lymph nodes and metastatic lymph node ratio, differentiation degree, vascular and perineural invasion, proximal surgical margin distance, adjuvant therapy, and the presence of postoperative complications were recorded. Results: The patients after radical surgery with a tumor size of <3 cm, macroscopic type non-ulcerative-infiltrative squamous cell carcinoma pathology, Stage 1 disease, pT1-2, pN0, well-differentiated groups, no perineural invasion, a metastatic lymph node ratio of <0.2, proximal surgery margin length of 5 to 10 cm, and no postoperative complications had higher five-year survival rates. However, when the effects of these factors on overall survival were examined independently, none of them had a statistically significant effect (p>0.05). The main factors affecting the prognosis were Stage ≥2 disease, postoperative complications, and proximal surgical margin less than 5 cm. Conclusion: Our study results suggest that Stage 1 disease, a proximal surgical margin length of more than 5 cm, and the absence of complications are associated with longer survival times and these patients are greatly benefited from surgical treatment.

Signal abnormalities of the bladder wall detected by native T1 mapping in patients with overactive bladder.

OBJECT: Native T1 mapping provides tissue-specific T1 relaxation times, which can be used to identify structural changes in the various organs. The object of this article was to evaluate the bladder wall of patients with overactive bladder using native T1 mapping and compare the relaxation times of patients and healthy controls. MATERIAL AND METHODS: Seventeen patients with a diagnosis of overactive bladder and 15 healthy controls were enrolled in this prospective study. All participants underwent pelvic MRI and T1 maps were acquired. Native T1 relaxation times were calculated via regions of interest acquired from the anterosuperior wall of the bladder in all participants. Mean T1 relaxation times of the overactive bladder patients were compared with those of controls. RESULTS: Overactive bladder patients had statistically significantly higher T1 relaxation times compared with controls (p = 0.004). In the subgroup analysis, there was no statistically significant difference between males (1113.42 ± 62.4) and females (1176.70 ± 100.9) regarding the T1 relaxation times (p = 0.165). There were no correlations between age and T1 relaxation times in patient or control groups (r = 0.057, p = 0.825, and r = 0.052, p = 0.932, respectively). CONCLUSION: Native T1 mapping can identify structural changes in the bladder wall of patients with overactive bladder. This technique has a promising role in the diagnosis of patients with suspected overactive bladder.

Red blood cell distribution width values in erectile dysfunction.

PURPOSE: Erectile dysfunction (ED) has increased prevalence by age and significantly affects the quality of life of men and their partners. To investigate the relationship between ED and red blood cell distribution width (RDW) values. MATERIALS AND METHOD: Between September 2019 and December 2019, a total of 192 individuals comprising those that were admitted to the urology outpatient clinic with ED complaints and healthy volunteers from among hospital staff were prospectively included in the study. The participants were divided into two groups according to the international erectile function index (IIEF-5) as ED group (n=148) and control group (n=44). RESULTS: There was no statistically significant difference between the two groups in terms of age, smoking status, presence of hypertension, triglyceride, low-density lipoprotein, high-density lipoprotein, total cholesterol, total prostate-specific antigen and haematocrit values. Body mass index, fasting blood sugar, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were significantly higher in the ED group (28.5±27.4kg/m2 vs 26.8±26.5kg/m2, p=.021, 109.05±49.7mg/dl vs 93.39±10.2mg/dl, p<.001, 2.18±1.3 vs 1.74±0.3, p=.031, and 113.7±47 vs 92.4±24.1, p=.004, respectively). The mean RDW values were 13.7±1.1 in the ED group and 13±0.5 in the control group (p<.001). The multivariate analysis revealed PLR [1.02 OR (1-1.04), p=.007] and RDW [2.75 OR (1.56-4.85), p<.001] as independent predictors for an ED diagnosis. CONCLUSION: Based on the strong relationship between RDW and ED, we consider that RDW may be a new indicator in the diagnosis of ED.

Genome-wide association links candidate genes to fruit firmness, fruit flesh color, flowering time, and soluble solid content in apricot (Prunus armeniaca L.).

BACKGROUND: Apricots originated from China, Central Asia and the Near East and arrived in Anatolia, and particularly in their second homeland of Malatya province in Turkey. Apricots are outstanding summer fruits, with their beautiful attractive color, delicious sweet taste, aroma and high vitamin and mineral content. METHODS AND RESULTS: In the current study, a total of 259 apricots genotypes from different geographical origins in Turkey were used. Significant variations were detected in fruit firmness (FF), fruit flesh color (FFC), flowering time (FT), and soluble solid content (SSC). A total of 11,532 SNPs based on DArT were developed and used in the analyses of population structure and association mapping (AM). According to the STRUCTURE (v.2.2) analysis, the apricot genotypes were divided into three groups. The mixed linear model with Q and K matrixes were used to detect the associations between the SNPs and four traits. A total of 131 SNPs were associated with FF, FFC and SSC. No SNP marker was detected associated with FT. CONCLUSION: The results demonstrated that AM had high potential of revealing the markers associated with economically important traits in apricot. The SNPs identified in the study can be used in future breeding programs for marker-assisted selection in apricot.

Effect of sunitinib on testicular oxidative and proinflammatory damage induced by ischemia-reperfusion in rats.

INTRODUCTION: This study aimed to biochemically and histopathologically investigate the effect of sunitinib on oxidative testicular damage induced by ischemia/reperfusion in rats. MATERIAL-METHOD: Experimental animals were divided into three groups of six rats each: testicular torsion-detorsion (TTD), sunitinib+testicular torsion-detorsion (STD), and sham control (SC). Sunitinib (25mg/kg) was administered orally to the STD group by gavage. Normal saline (0.9% NaCl) was administered orally to the TTD and control groups as the solvent. One hour after administration of sunitinib and 0.9% NaCl, all animal groups were done torsion-detorsion. Then, all the rats were killed by high-dose anesthesia, and their testicles were removed. Biochemical and histopathological examinations were performed on the removed testicular tissues. RESULTS: Malondialdehyde; it was observed that the results in the STD group were close to those of the SC group and statistically significant lower compared to the TTD group (p=0.001). The glutathione values were statistically significantly higher in the STD group compared to the TTD group (p<0.001). Nuclear factor kappa B values, revealing a statistically significant difference between the TTD and STD groups (p<0.001). The TNF-α levels were measured and indicating that the results of the STD group were statistically significantly lower than those of the TTD group (p<0.001). Histopathologically, animal tissues given sunitinib were observed to resemble normal tissues. CONCLUSION: Sunitinib was shown to prevent histopathological changes in testicular tissue against ischemia/reperfusion damage.

The Role of Family Influence and Academic Satisfaction on Career Decision-Making Self-Efficacy and Happiness.

Careers are a reality of life that need to be considered as multi-dimensional in today's modern societies. Choosing a career is a complex process that coincides with high school and university ages, creating psycho-social stress. Considering the literature, the effects of different environmental factors have been revealed in separate studies. This study examines both individual and environmental factors together. By adopting a quantitative research method, we collected cross-sectional data through online questionnaires from 1130 university students. The association of family influence and academic satisfaction with happiness through career decision self-efficacy was meaningful using gender, age, income, and parents' education as control variables. Family influence and academic satisfaction were positively correlated with career decision self-efficacy and happiness. In conclusion, we found that family influence and support, students' work, and academic satisfaction are positively significant in terms of the career process and happiness. It was understood that the career reality should be considered with a holistic view that includes family, school, and work experience.

Relationship between urolithiasis and the fat halo sign.

INTRODUCTION: This study aimed to examine the relationship between urolithiasis and gastric wall fat halo sign (FHS). MATERIALS AND METHOD: The data of 382 patients who presented to our clinic with the complaint of flank pain were analyzed retrospectively. According to the results of noncontrast computed tomography, the patients were divided into two groups those with ureteral stones (Group 1) and those without urinary stones (Group 2). The patients' age, gender, weight, height, body mass index (BMI), cholesterol, triglyceride, blood urea nitrogen, creatinine, and gastric wall FHS data were evaluated. RESULTS: When Groups 1 and 2 were compared in terms of FHS positivity, FHS was detected in 140 (57.3%) of 244 patients in Group 1 and 24 (17%) of 138 patients in Group 2, indicating a statistically significant difference (P < .001). CONCLUSION: A statistically significant relationship was found between urinary stone disease and gastric wall FHS.
