Background.While tobacco use by a renal transplant recipient has been shown to negatively affect graft and patient survival, the effect of smoking on the part of the kidney donor remains unknown.Methods.29 smoking donors (SD) and their recipients (SD-R) as well as 71 non-smoking donors (ND) and their recipients (ND-R) were retrospectively reviewed. Preoperative demographics and perioperative variables including serum creatinine (Cr) and glomerular filtration rate (GFR) were calculated and stratified by amount of tobacco exposure in pack-years. Clinical outcomes were analyzed with a Student'st-test, chi-square, and multiple linear regression analysis ().Results.At most recent followup, SD-R's had a significantly smaller percent decrease in postoperative Cr than ND-R's (−57% versus −81%; ) and lower calculated GFR's (37.0 versus 53.0 mL/min per 1.73 m2; . SD's had a larger percent increase in Cr than ND's at most recent followup (57% versus 40%; ), with active smokers having a larger increase than those who quit, although this difference was not statistically significant (68% versus 52%; ).Conclusions.Use of tobacco by kidney donors is associated with decreased posttransplant renal function, although smoking cessation can improve outcomes. Kidneys from donors who smoke should be used with caution.

Abstract Purpose: To determine the pathophysiology of nocturnal polyuria associated with renal dysfunction.Methods: Patients who underwent laparoscopic nephrectomy were studied prospectively. The diurnal variation in urine volume, osmolality, and salt excretion were measured on preoperative day two and postoperative day seven. The factors associated with an increase in the nighttime urine volume rate with decreased renal function were evaluated by multiple linear regression analysis.Results: Forty-nine patients were included. The eGFR decreased from 73.3 ± 2.0 to 47.2 ± 1.6 mL/min/1.73 m2 (P < 0.01) and the nighttime urine volume rate increased from 40.6% ± 2.0% to 45.3% ± 1.5% (P = 0.04) with nephrectomy. The nighttime urine osmolality decreased from 273 ± 15 to 212 ± 10 mOsm/kg (P < 0.01) and the nighttime salt excretion rate increased from 38.7% ± 2.1% to 48.8% ± 1.7% (P < 0.01) with nephrectomy. Multiple linear regression analysis revealed that the increase in the nighttime urine volume rate was strongly affected by the increase in the nighttime salt excretion rate.Conclusion: A decrease in renal function causes an increase in the nighttime urine volume rate, mainly due to an increase in nighttime salt excretion.Trial registration number: UMIN000036760 (University Hospital Medical Information Network Clinical Trials Registry)Date of registration: From June 1st, 2019 to October 31th 2020

Abstract BACKGROUND The phenotype of diabetic kidney disease represents a lower estimated glomerular filtration rate (eGFR) and albuminuria. We investigated the association between day-by-day home blood pressure (BP) variability and the eGFR in subjects with diabetes and compared this association with that in subjects without diabetes. We then attempted to determine whether the association is present in albuminuria. METHODS We analyzed 4,231 patients with risk factors of cardiovascular disease (24.4% with diabetes) from the J-HOP (Japan Morning Surge-Home Blood Pressure) study. Home BP was measured in the morning and evening for 14 days. We calculated the SD, coefficient of variation, average real variability (ARV), and variation independent of the mean of the subjects’ morning and evening home systolic BP (SBP) as the indexes of day-by-day home BP variability. RESULTS A multiple linear regression analysis adjusted for covariates showed both average morning and evening SBP were associated with the log-transformed urine albumin-to-creatinine ratio (UACR) with and without diabetes (all P &lt; 0.05), but not with the eGFR except for an association of average evening SBP in the no-diabetes group. None of the indexes of day-by-day morning and evening home SBP variability were associated with the log-transformed UACR except for the association between the ARV of home morning SBP in the diabetes group. All of the indexes of day-by-day morning and evening home SBP variability were associated with the eGFR only in the diabetes group (all P &lt; 0.05). CONCLUSIONS The association between increased day-by-day home BP variability and impaired renal function was unique in diabetes.

Background: Osteoporosis is one of the main causes of morbidity in patients with thalassemia major. Osteoprotegerin (OPG) is secreted by osteoblasts and osteogenic stromal stem cells and protects the skeleton from excessive bone reabsorption. In this study, the authors aimed to assess the relationship between OPG with osteoporosis and osteopenia in patients with thalassemia major. Materials and Methods: In this analytic cross-sectional study, 37 patients aged 8-18 years, with thalassemia major were enrolled. Biochemical markers including hemoglobin, ferritin, calcium, phosphorus levels, and MRI T2* heart and liver were assessed. A bone mineral densitometry (BMD) was performed as well. Statistical analysis was performed by the independent T-test and Chi-Square test using the SPSS 20. The Multiple linear regression analysis was used to investigate the association between the BMD Z-score and OPG by the effect modification. Results: The mean age of patients was 14.86±3.72 years. Normal bone density, osteopenia, and osteoporosis were noted in 2 (5.4%), 21 (56.8%), and 14 (37.08%) patients, respectively. The number of girls (P=0.042), mean age (P=0.045), and MRI T2* heart (P=0.033) in patients with osteopenia was significantly higher than patients with osteoporosis. The BMD Z-score was not significantly associated with OPG regarding the total number of participants, whereas in patients with osteoporosis, this association was significant (P=0.001). In all effect modified models, BMD remained statistically non-significant except for body mass index modification (P=0.046). Conclusion: Based on the results, it seems that further complicated studies are needed to be performed on this issue.

Leukotrienes are inflammatory and vasoactive mediators implicated in endothelium-dependent relaxations and atherosclerosis. Urinary leukotriene E4(U-LTE4) is a validated disease marker of asthma and increases also in diabetes and acute coronary syndromes. The aim of the present study was to evaluate the association of U-LTE4and CRP with endothelial function. Urine samples were obtained from 30 subjects (80% males; median age 65) with type 2 diabetes of at least two years duration and a median glomerular filtration rate (eGFR) of 71 (14–129) mL/min. Reactive hyperemia index (RHI) was used as a measure of microvascular endothelial function, whereas macrovascular endothelial function was determined be means of flow-mediated dilatation of the brachial artery (FMD). Decreased renal function was associated with lower concentrations of U-LTE4. In addition, U-LTE4was correlated with serum creatinine (R=−0.572;P=0.001) and eGFR (R=0.517;P=0.0036). A stepwise multiple linear regression analysis identified eGFR as an independent predictor of U-LTE4concentrations. In conclusion, the present results did not establish an association of U-LTE4with endothelial dysfunction. However, eGFR was an independent predictor of U-LTE4, but not CRP, in this cohort, suggesting that GFR should be considered in biomarker studies of U-LTE4.

INTRODUCTION: The aim of this retrospective study was to compare the occlusal outcomes, duration and efficiency of Class I malocclusion treatment carried out with and without premolar extractions in patients with different degrees of initial malocclusion severity. METHODS: Complete records of 111 patients were obtained and divided into two groups: Group 1 consisted of 65 patients at an initial mean age of 13.82 years old treated with four premolar extractions; whereas Group 2 consisted of 46 patients at an initial mean age of 14.01 years old treated without extractions. Two subgroups were obtained from each group (1A, 1B, 2A and 2B) with different degrees of malocclusion severity according to the initial values of PAR index. Compatibility was assessed using chi-square and t-tests. The subgroups were compared by means of Analysis of Variance (ANOVA).The variables that might be related to treatment duration and efficiency were assessed using the multiple linear regression analysis. RESULTS: Initial malocclusion severity was positively related to the amount of occlusal correction and consequently to a higher efficiency index. Moreover, extraction protocol showed a positive relationship with treatment duration and a negative relationship with treatment efficiency. CONCLUSION: Extraction and non-extraction protocols for correction of Class I malocclusion provide similar satisfactory results; however, the extraction protocol increases the overall treatment duration. Orthodontic treatment is more efficient in cases with high initial malocclusion severity treated with a non-extraction protocol.

OBJECTIVE: We aimed to determine the serum level of fibroblast growth factor-23 (FGF-23) in patients with primary hyperparathyroidism (pHPT) to understand its physiological role in the disorder. PATIENTS AND METHODS: Ninety-eight patients with pHPT who underwent parathyroidectomy formed the study group. We also measured serum FGF-23 in 11 of these patients on postoperative day 6. RESULTS: Serum FGF-23 levels was significantly higher in pHPT patients than in healthy controls (35.6+/-17.8 ng/l vs 28.9+/-11.2 ng/l (mean+/-s.d.); P<0.001 (Pearson's correlation coefficient)), but there was no significant difference in the serum FGF-23 level between pHPT patients with normal renal function (creatinine clearance (Ccr) of >or=70 ml/min) and healthy controls. Serum FGF-23 correlated positively with serum calcium (P<0.0001) and intact parathyroid hormone (PTH) (P<0.01), and negatively with Ccr (P<0.001), serum phosphate (P<0.05), and serum 1,25-dihydroxyvitamin D (1,25(OH)(2)D) (P<0.05). Multiple linear regression analysis of factors potentially determining serum FGF-23 levels in pHPT patients showed serum calcium (P<0.01) and Ccr (P<0.001) to be significant predictors. The serum levels of FGF-23 did not change after parathyroidectomy despite the normalization of serum calcium values. Multiple linear regression analysis revealed that serum FGF-23 was not a significant predictor of serum phosphate or 1,25(OH)(2)D in pHPT patients. CONCLUSIONS: FGF-23 may not play a significant role in regulating phosphate or 1,25(OH)(2)D in pHPT patients, especially in those with normal renal function. Further studies are warranted to determine the role of FGF-23 in renal insufficiency or failure.

AbstractTo determine the pathophysiology of nocturnal polyuria associated with renal dysfunction, patients who underwent laparoscopic nephrectomy were prospectively studied. The diurnal variation in urine volume, osmolality, and salt excretion were measured on preoperative day 2 and postoperative day 7. The factors associated with an increase in the nighttime urine volume rate with decreased renal function were evaluated using multiple linear regression analysis. Forty-nine patients were included. The estimated glomerular filtration rate decreased from 73.3 ± 2.0 to 47.2 ± 1.6 mL/min/1.73 m2 (P < 0.01) and the nighttime urine volume rate increased from 40.6% ± 2.0% to 45.3% ± 1.5% (P = 0.04) with nephrectomy. The nighttime urine osmolality decreased from 273 ± 15 to 212 ± 10 mOsm/kg and the nighttime salt excretion rate increased from 38.7% ± 2.1% to 48.8% ± 1.7% (both P < 0.01) with nephrectomy. Multiple linear regression analysis showed that the increase in the nighttime urine volume rate was strongly affected by the increase in the nighttime salt excretion rate. A decrease in renal function causes an increase in the nighttime urine volume rate, mainly because of an increase in nighttime salt excretion.Trial registration number: UMIN000036760 (University Hospital Medical Information Network Clinical Trials Registry).Date of registration: From 1 June 2019 to 31 October 2020.
