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.
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.
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.
The patency of vascular access is of great significance to hemodialysis patients. Combining with guidelines and literature associated with vascular access for dialysis in recent years, the authors interpret the effectiveness and limitations of prophylactic drug strategies, including using fish oil, anticoagulation, anti-platelet, lipid-lowering agents, etc., in order to promote the proper use of these agents in clinical practice, and improve the effect of prophylaxis and treatment of vascular access dysfunction.
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.
