    Peripheral Muscle Strength Indicates Respiratory Function Testing in Renal Recipients
    (2017) Ulubay, Gaye; Uyanik, Saliha; Dedekarginoglu, Balam Er; Serifoglu, Irem; Kupeli, Elif; Bozbas, Serife Savas; Sezer, Siren; Haberal, Mehmet; 0000-0002-5826-1997; 0000-0002-7230-202X; 0000-0002-3462-7632; 0000-0003-2478-9985; 28260479; AAB-5345-2021; AAI-8064-2021; AAJ-8097-2021; AAB-5064-2021; AAS-6628-2021
    Objectives: Muscle wasting occurs in renal recipients due to decreased physical performance, and de creased respiratory muscle strength may occur due to changes in structure and function. Data are scarce regarding the roles of sarcopenia and nutritional status on respiratory muscle function in these patients. Here, we evaluated interactions among peripheral muscle strength, sarcopenia, nutritional parameters, and respiratory muscle function in renal transplant recipients. Materials and Methods: Ninety-nine patients were prospectively enrolled between September and April 2016 at Baskent University. Forced vital capacity values (via pulmonary function tests), respiratory muscle strength (via maximal static inspiratory and expiratory pressures), and peripheral muscle strength (via hand grip strength test) were recorded. Nutritional para meters, fat weight, arm circumference, waist circumference, and C-reactive protein levels were also recorded. Results: Of 99 patients, 68 were renal transplant recipients (43 men, mean age: 39.09 +/- 10.70 y) and 31 were healthy participants (14 men, mean age: 34.94 +/- 10.95 y). Forced vital capacity (P < .001, r = 0.65), maximal inspiratory (P = .002, r = 0.39) and expiratory (P < .001, r = 0.4) pressure, and hand grip strength showed significant relations in transplant recipients. Positive correlations were found between serum albumin levels and both hand grip strength (P = .16, r = 0.347) and forced vital capacity (P = .03, r = 0.436). Forced vital capacity was statistically different between renal recipients and healthy participants (P = .013), whereas maximal inspiratory and expiratory pressures were not (P > .05). No statistically significant relation was observed between biochemical para meters and maximal inspiratory and expiratory pressures (P > .05). Conclusions: Respiratory function and peripheral muscle strength were significantly related in renal transplant recipients, with significantly lower peripheral muscle strength suggesting the presence of inadequate respiratory function. Peripheral and respiratory muscle training and nutritional replacement strategies could help to improve postoperative respiratory function.

    Association Between Preoperative Pulmonary Risk Scores and Postoperative Complications in Renal Transplant Recipients
    (2016) Kupeli, Elif; Dedekarginoglu, Balam Er; Ulubay, Gaye; Haberal, Mehmet; 0000-0002-5826-1997; 0000-0003-2478-9985; 0000-0002-3462-7632; 27805520; AAB-5345-2021; AAB-5064-2021; AAJ-8097-2021
    Objectives: Patients who are being considered for renal transplant must undergo thorough preoperative pulmonary evaluation to determine risk of post operative pulmonary complications. The aim of this study was to determine the relation between the preoperative pulmonary risk factor score and pulmonary complications in patients undergoing renal transplant. Materials and Methods: Medical records of patients who underwent renal transplant at our institution between 2004 and 2015 were retrospectively reviewed. Patient demographics, smoking history, comorbidities, and preoperative pulmonary risk factors (age, oxygen saturation, hemoglobin level, type of incision, duration of surgery, history of lower respiratory tract infection 1 month before surgery, urgency of surgery), and type of pulmonary complications within 1 month after transplant were recorded. Results: Our study included 131 patients (94 male patients; mean age of 38.25 +/- 12.96 y). Of total patients, 21(16%) developed complications during the first month after transplant, with 10 of the 21 (7.6% overall) developing pulmonary complications. These complications were pleural effusion (2 patients), pneumonia (3 patients), respiratory failure (2 patients), and pulmonary embolism (1 patient). There were no deaths directly attributed to the pulmonary complications. A significant correlation was observed between the preoperative pulmonary risk factor score and postoperative pulmonary complications in renal transplant recipients (P =.003). A positive correlation between the preoperative pulmonary scores and postoperative pulmonary complications existed among life-long nonsmokers (r = 0.371; P =.003). Conclusions: Renal transplant is an established modality in treatment of chronic renal failure. Prevention of pulmonary complications is essential for successful outcomes following transplant. Health care professionals involved with renal transplant and transplant centers should be aware of preoperative pulmonary risk factors. Patients should be observed so that these risk factors can be reduced before planned transplant. Moreover, we also suggest that smoking history should be considered as a preoperative pulmonary risk factor as it was found to be a factor leading to postoperative pulmonary complications in our study.
