Item Utility Of Continuous Performance Test (MOXO-CPT) In Children With Pre-Dialysis Chronic Kidney Disease, Dialysis And Kidney Transplantation(2022) Buyukkaragoz, Bahar; Soysal Acar, A. Sebnem; Ekim, Mesiha; Bayrakci, Umut Selda; Bulbul, Mehmet; Caltik Yilmaz, Aysun; Bakkaloglu, Sevcan A.; 000829126000001Background Children with chronic kidney disease and on kidney replacement therapy may have neurocognitive and psychosocial disorders. Although kidney transplantation improves quality of life, psychological problems may exist in children who undergo kidney transplantation. Herein, we aimed to investigate attention-deficit hyperactivity disorder-like symptoms with MOXO-continuous performance test in children with pre-dialysis chronic kidney disease, dialysis and kidney transplantation. Methods The MOXO-continuous performance test measures four domains of attention-deficit hyperactivity disorder-like symptoms, including attention, timeliness, hyperactivity and impulsivity. Patients with at least three scores < - 1.5 standard deviations were considered as positive to MOXO-continuous performance test. Test scores of the pre-dialysis chronic kidney disease, dialysis (divided into peritoneal dialysis and hemodialysis subgroups) and kidney transplantation groups were compared. Correlations of test scores with the patient's clinical and laboratory characteristics and effects of hospitalizations and schooling were assessed. Results Seventy-two patients aged 13.3 +/- 3.4 years (23 with kidney transplantation, 23 on dialysis and 26 with pre-dialysis chronic kidney disease) were evaluated. Overall MOXO-continuous performance test positivity was 29%. No differences were detected between the three groups concerning total or z scores. Attention and timeliness z scores were significantly higher in females (p = 0.004 and p = 0 .008 , respectively). Age was positively correlated to attention and timeliness total scores (p = 0.000, r = 0.445 and p = 0.004, r = 0.243, respectively), and inversely correlated to hyperactivity total scores (p = 0.000, r = - 0.415). Conclusions Prevalence of attention-deficit hyperactivity disorder-like symptoms in the study population was much higher than that of pediatric attention-deficit hyperactivity disorder. We believe that the MOXO-continuous performance test is a valid supportive measure for evaluation of attention-deficit hyperactivity disorder diagnosis in children with various stages of chronic kidney disease or on kidney replacement therapy.Item Acoustic Radiation Force Impulse Elastography Findings of Achilles Tendons in Patients on Chronic Hemodialysis and in Renal Transplant Patients(2021) Rahatli, Feride Kural; Turnaoglu, Hale; Haberal, Kemal Murat; Kirnap, Mahir; Fidan, Cihan; Sayin, Cihat Burak; Uslu, Nihal; Haberal, Mehmet; 0000-0002-8211-4065; 0000-0002-9093-1524; 0000-0002-9093-1524; 30398098; R-9398-2019; F-5830-2019; F-5830-2019Objectives: The Achilles tendon, which is composed of tendinous parts of gastrocnemius and soleus muscles, is the strongest and the largest tendon in the human body. Chronic renal disease can lead to reduced physical activity and exercise capacity. Spontaneous rupture of the Achilles tendon can occur in patients with chronic renal failure, with recurrent microtraumas, hypoxia, and chronic acidosis as predisposing factors. Here, we assessed and compared the elastographic findings in the Achilles tendon using acoustic radiation force impulse elastography in patients on chronic hemodialysis, in renal transplant patients, and in healthy volunteers. Materials and Methods: Our study included 25 patients on chronic hemodialysis, 25 renal transplant patients, and 25 healthy individuals (control group). The thickness and shear wave velocity of the Achilles tendons were measured bilaterally by ultrasonography and acoustic radiation force impulse elastography. Results: The mean shear wave velocity was 3.67 m/s in the right and 3.64 m/s in the left Achilles tendon in the hemodialysis group. In the renal transplant group, the mean shear wave velocity was 4.29 and 4.25 m/s for the right and left Achilles tendon, respectively. In the control group, the mean shear wave velocity was 6.68 and 6.59 m/s, respectively for the right and left Achilles tendon. A statistically significant difference in shear wave velocities was shown among the groups (P<.05). Conclusions: Achilles tendons in patients with chronic renal failure and on hemodialysis were softer than in renal transplant patients and softer than in the control group. Chronic tendinopathy causes softening of the tendon. In the renal transplant group, stiffness of the Achilles tendon was increased versus the hemodialysis group but still softer than the control group, which could be explained as a positive clinical effect of renal transplant. Acoustic radiation force impulse elastography is an objective, easy, and noninvasive method to assess Achilles tendinopathy.Item The New Anterior Less Invasive Crescentic Incision for Living Donor Nephrectomy(2020) Haberal, Mehmet; Soy, Ebru H. Ayvazoglu; Akdur, Aydincan; AlShalabi, Omar; Yildirim, Sedat; Moray, Gokhan; Torgay, Adnan; 0000-0002-8726-3369; 0000-0002-3462-7632; 0000-0002-5735-4315; 0000-0002-0993-9917; 0000-0002-6829-3300; 0000-0003-2498-7287; 33143599; AAA-3068-2021; AAJ-8097-2021; AAF-4610-2019; AAC-5566-2019; AAJ-5221-2021; AAE-1041-2021Objectives: Living-donor nephrectomy is a devoted procedure performed in a healthy individual; for these procedures, it is essential to complete the surgery with the lowest possible risk and morbidity and allow donors to regain their normal daily activity. To minimize anatomic and physiologic damage, we modified a surgical technique. Here, we report our experiences with the new anterior less invasive crescentic donor nephrectomy technique. Metarials and Methods: We retrospectively evaluated 728 donor nephrectomy patients who had the new anterior less invasive cresentic incision (n = 224), the classic open (n = 431), or the laparoscopic living-donor nephrectomy (n = 73) procedures. Demographic characteristics, preoperative and postoperative parameters, acute renal graft dysfunction, and firstyear graft and patient survival rates were compared between groups. Results: During the operation, the new cresentic incision living-donor nephrectomy allowed a safe and comfortable position for the patient and the anesthesiologist. Also, it procures safe access especially for grefts with multiple vessels. Patients had lower pain scores (P = .010), shorter hospital stays (2.25 vs 3.49 days) than those who received the classic open living-donor nephrectomy. Patients who received laparoscopic living-donor nephrectomy had significantly longer mean operation time (P = .016) and warm ischemia time (P <= .001) than those who had the new cresentic incision technique. All groups showed similar rates of first-year survival and delayed graft dysfunction. Conclusions: The new anterior less invasive cresentic incision open-donor nephrectomy approach is a safe, comfortable, effective, and less invasive modification of the living donor nephrectomy. Also, it procures safe access for grefts with multiple vessels.
