Secondary and tertiary hyperparathyroidism are common complications in patients with chronic kidney disease, especially in end stage renal disease. Surgery is an important method for the treatment of secondary and tertiary hyperparathyroidism. The American Association of Endocrine Surgeons Guidelines for the Definitive Surgical Management of Secondary and Tertiary Renal Hyperparathyroidism is the first evidence based guideline focus on renal hyperparathyroidism surgical management. Recommendations using the best available evidence by a panel of 10 experts in secondary and tertiary renal hyperparathyroidism constructed this guideline, which provides evidence-based, individual and optimal surgical management of secondary and tertiary renal hyperparathyroidism. This paper made a guideline interpretation on the indications of surgery, imaging examination, preoperative and perioperative management, relevant evaluation and treatment during perioperative period, and intraoperative parathyroid hormone monitoring during operation, and so on.
Objective The basic terms of the technical specifications for case-control studies in the field of traditional Chinese medicine (TCM) are formed by expert consensus methods, in order to develop detailed texts of the technical specifications. Methods According to the process of international guidelines, a total of 44 experts participated in the Delphi survey. Results The three rounds of questionnaire response rates were 73.3%, 86.4%, and 86.8%, respectively. The experts' authority coefficients were 0.82, 0.85, and 0.86, respectively; and the expert opinion coordination coefficients were 0.356, 0.349, and 0.422, respectively. Expert enthusiasm, authority, opinion centralization, and degree of coordination were relatively high. There were many opinions raised in the expert consensuses on how to measure TCM syndrome, TCM constitution, the time point of measurement and the selection of new cases. Conclusion The case-control studies in TCM field should pay more attention to the characteristics of TCM. The draft of technical specification involves the study design and reporting, which can improve the methodological and reporting quality of case-control studies.
ObjectiveThis study aimed to revise the perioperative recovery scale for integrative medicine (PRSIM) based on item response theory (IRT). MethodsUnder the guidance of IRT, a total of 349 patient data collected during the development of the original version of PRSIM at Guangdong Provincial Hospital of Chinese Medicine were used. Principal component analysis was performed using SPSS 18.0 software to test the unidimensionality. The R language was utilized for parameter estimation, including discrimination coefficient, difficulty parameters and information content, as well as drawing item characteristic curves to assess item quality and estimate item functioning differences. A comprehensive screening process was carried out by combining expert consultations, patient evaluations, and discussions within a core group. ResultsThe degree of discrimination of all items ranged from ?0.535 to 2.195. The difficulty coefficient ranged from ?10.343 to 5.461, and the average information content of all items ranged from 0.043 to 1.075. Based on the criteria for parameter selection, nine items were retained. The results of expert consultations indicated the removal of 5 items and the modification of 7 items. After discussion within the core group, a final decision was made to remove 5 items. ConclusionBased on a synthesis of IRT and expert consultation feedback, and following discussions within the core group, a revised version comprising 15 items is retained and modified from the original 20 items.
ObjectiveTo investigate the role of multiple disciplinary team (MDT) during surgical treatment of renal secondary hyperparathyroidism (SHPT), and identify management points of Departments of Nephrology and Endocrinology.MethodsThe data of patients with chronic kidney disease undergoing surgical treatment for SHPT in West China Hospital of Sichuan University between January 2009 and December 2018 were retrospectively collected. We explained the surgical treatment of MDT in the management of renal SHPT, and compared the changes before and after the establishment of MDT.ResultsA total of 187 patients including 101 males and 86 females were enrolled, with an average age of (47.60±11.28) years old and median dialysis vintage of 7 years. Under MDT, the number of patients with parathyroidectomy increased [(8.50±5.10) vs. (59.50±2.12) patients/year, P<0.001] and the completion rate of preoperative examinations were greatly improved (P<0.001). The success rate of surgery was also increased (86.8% vs. 97.5%, P=0.010). Proportion of patients who were admitted to the Department of Nephrology was significantly increased (39.7% vs. 84.9%, P<0.001). Most patients after surgery were transferred to the Department of Endocrinology (5.9% vs. 77.3%, P<0.001) to manage postoperative complications and metabolic bone disease, and thus normalized the management of SHPT.ConclusionsThe MDT contributes to management of renal SHPT, which is worthy of popularization and spreading. The management of internal medicine departments during surgical treatment of SHPT based on MDT is important, because they can be helpful to complete preoperative examinations and preoperative preparation as well as to alleviate postoperative complications.
Objective
To observe the prognosis of pregnant patients with renal failure who underwent blood purification.
Methods
Pregnant patients with renal failure undergoing blood purification (hemodialysis or hemofiltration) from January 2009 to February 2017 were included in this study. Clinical data and pregnancy outcome were collected retrospectively.
Results
A total of 42 patients were enrolled in this study, including 38 with acute renal failure, 3 with chronic progressed renal failure, and 1 with chronic renal failure. There were 5 patients (11.9%) with chronic kidney disease (CKD) before pregnancy, 3 (7.2%) with systemic lupus erythematosus, 24 (54.8%) with hypertension, 5 (11.9%) with acute pancreatitis, and 7 (14.3%) with acute liver failure. In perinatal period, 7 patients (16.7%) died, whose underlying diseases were acute pancreatitis in 2, lupus nephritis in 1, acute hepatic failure in 3, and pulmonary tuberculosis breakout in 1. There were 5 patients with twin pregnancy, and 37 patients with single pregnancy. In the 28 patients with natural pregnancy ending, the live birth rate was 82.1% (23/28), and the live birth rate of twin pregnancy was only 50% (5/10). Twenty-seven patients were followed up, in whom 10 were in end stage of renal disease (ESRD), which was correlated with hypertension (P=0.001), and 3 patients were in CKD 1–4. Renal diseases were completely recovered in 14 patients. New CKD were diagnosed in 8 patients, without any correlated factor.
Conclusions
For pregnant patients with renal failure undergoing hemodialysis or hemofiltration, the death risk and the dead birth rate are high. Patients with hypertension or pre-existed renal failure have higher risk for ESRD. Some patients are not completely recovered from acute renal failure, with CKD left.
The estimation of the minimal important difference (MID) in patient-reported outcomes (PRO) relies on various selection principles and statistical methods, resulting in varying degrees of credibility among studies. When applying these findings, it is crucial to consider their evaluation outcomes. In the context of widely accepted MID studies based on the anchoring method, the credibility of the MID of PRO is influenced by the selection of anchors and the statistical methods employed for estimation. Variations in the anchors utilized, differences in clinical trial designs, disparities in the characteristics of measurement subjects and environment, as well as the control of biases in studies, can all contribute to inconsistencies in the MID of PRO. In response to this, McMaster University in Canada has developed a credibility evaluation tool specifically for MID studies in PRO. The tool comprises five core items and four additional items. The five core items encompass an evaluation framework that assesses: (1) Is the patient or necessary proxy responding directly to both the PRO and the anchor? (2) Is the anchor easily understandable and relevant for patients or necessary proxy? (3)Has the anchor shown good correlation with the PRO? (4) Is the MID precise? (5) Does the threshold or difference between groups on the anchor used to estimate the MID reflect a small but important difference? The four additional items concerning transition-rated anchors assess: (1) Is the amount of elapsed time between baseline and follow-up measurement for MID estimation optimal? (2) Does the transition item have a satisfactory correlation with the PRO score at follow-up? (3) Does the transition item correlate with the PRO score at baseline? (4) Is the correlation of the transition item with the PRO change score appreciably greater than the correlation of the transition item with the PRO score at follow-up? Given the relative weights of each item in the tool are uncertain and environment-dependent, items are not scored; instead, an overall judgment is made using a qualitative rating approach. This article introduces the specific items of this tool and illustrates the evaluation process through a case study to improve its use in optimizing PRO results presentation and interpretation in clinical trials, reviews, assessments, and guidelines.
