Background: Parathyroidectomy is the only definitive treatment for primary hyperparathyroidism (PHPT). Precise localization of abnormal glands is a key to a successful surgery. Most patients are expected to be successfully treated with focused parathyroidectomy. However, this approach is associated with a risk of existing multiglandular disease which may lead to the postoperative persistence of PHPT., Methods: Eight hundred ten patients who underwent an initial surgery for PHPT at SPBU Hospital in 2017-2018 were included in the study. Preoperative imaging results were evaluated. Multivariate logistic regressions were calculated to estimate predictive values of preoperative data for the risk of postoperative persistence and risk of MGD., Results: Multiglandular disease was found to be a leading cause of persistent hyperparathyroidism. An anamnesis of thyroid surgery was found to be a significant risk factor for the persistence of hyperparathyroidism. The rate of persistence did not differ significantly between groups with bilateral neck exploration and focused parathyroidectomy. Age, sex, body mass index as well as negative results of preoperative US, MIBI, and 4D CT were not independently associated with a higher risk of MGD. All preoperative imaging modalities showed from low to moderate sensitivity for the detection of MGD. The frequency of cases of a missed second adenoma did not differ significantly between patients with concordant and discordant preoperative data. There were 7 cases with previously unsuspected second adenomas found solely due to bilateral neck exploration., Conclusions: None of the combination of preoperative visualization modalities was able to rule out the MGD and reliably identify patients for focused parathyroidectomy. Additional preoperative visualization failed to improve overall results. Bilateral neck exploration appeared to have a slight benefit for the patients with concordant preoperative imaging results., (© 2022.

Background: Precise localization of abnormal parathyroid glands is important for a successful surgery for primary hyperparathyroidism (PHPT). While a large number of patients can be successfully treated with the focused parathyroidectomy, there is a considerable rate of the persistent PHPT mostly because of undetected multiglandular disease (MGD)., Aim: The aim of the study was to evaluate the meaning of preoperative visualization data for planning the surgery for patients with PHPT., Materials and Methods: The study was conducted at SPBU Hospital in 2017-2018. 810 patients who underwent a primary surgery for PHPT were included in the study. Preoperative imaging results were investigated and multivariative logistic regressions were calculated to assess the predictive values of preoperative data. The rate of cases with persistent disease and cases with MGD were compared between patients with different results of preoperative data., Results: Age, sex, body mass index, negative results of preoperative US, MIBI and 4D CT were not independently associated with the higher risk of multiglandular disease. The larger number of performed preoperative visualization studies were associated with the higher risk of persistence. 37% cases of MGD were not identified preoperatively. There were 7 cases with previously unsuspected second adenomas found only due to bilateral neck exploration., Conclusion: Any combination of preoperative visualization modalities was not able to rule out the MGD reliably. Efficacy of surgical treatment was not associated with the higher number of preoperative studies. Bilateral neck exploration may decrease the rate of the persistent hyperparathyroidism improving the identification of multiglandular disease.

Objectives: The aim of this study was to investigate the relationship between malnutrition and long-term survival in patients who underwent cardiopulmonary bypass (CPB)., Methods: This study analyzed the long-term survival data of a mixed cohort of 1187 cardiac patients previously enrolled in a prospective observational study of nutritional screening in cardiac surgery. Nutritional status was assessed using the Malnutrition Universal Screening Tool (MUST). The mean age of patients was 58.86 ± 10.07 y (95% confidence interval [CI], 58.2-59.4). The median time of follow-up was 73.4 mo (25th-75th percentiles, 18.3-101.3)., Results: In all, 449 patients (37.8%) were lost to follow-up after hospitalization. For the remaining participants, the overall 8-y survival was 68% (95% CI, 59-76) and 77% (95% CI, 73-80; log-rank, P = 0.12) in patients with and without malnutrition risk, respectively. Statistically significant differences in survival were found during the 3-y follow-up of patients with heart valve disease: 83% (95% CI, 74-92) with malnutrition versus 93% (95% CI, 90-96) without malnutrition (log-rank, P = 0.03). The final multivariate Cox regression model revealed logistic EuroSCORE (hazard ratio (HR), 1.337; 95% CI, 1.110-1.612), cardiopulmonary bypass time <110.5 min (HR 0.463, 95% CI 0.255-0.842), preoperative albumin (HR 0.799, 95% CI 0.691-0.924), and C-reactive protein (HR, 1.106; 95% CI, 1.018-1.202) as independent predictors of 3-y survival., Conclusion: Preoperative malnutrition is not associated with 8-y mortality in a mixed cardiac surgery cohort. However, it may be associated with worse 3-y outcomes in patients with heart valve disease., (Copyright © 2020 Elsevier Inc. All rights reserved.)

The data article refers to the paper titles "Impact of malnutrition on long-term survival in adult patients after elective cardiac surgery" [1]. The data refer to the analysis of the relationship between baseline malnutrition and long-term mortality after cardiac surgery. Baseline demographic, nutritional, and medical history data were collected for each enrolled patient. Baseline serum albumin and C-reactive (CRP) protein levels were also obtained. Surgical risk was assessed in accordance with the logistic EuroSCORE. Intraoperative data including cardiopulmonary bypass (CPB) time and postoperative characteristics, such as postoperative complications, number of days in the ICU, and hospitalization duration, were also collected. Data on nutritional status were collected using four nutritional screening tools: (1) malnutrition universal screening tool (MUST), (2) short nutritional assessment questionnaire (SNAQ), (3) mini-nutritional assessment (MNA), and (4) nutritional risk screening 2002 (NRS-2002). Both electronic medical records and phone interviews were used for survival data collection. ROC analysis was performed to analyze prognostic value of baseline and perioperative variables on long-term mortality. Univariate and multivariate logistic regression analysis of predictors of 3- and 8-year mortality were performed. Kaplan-Meyer curves, describing the impact of baseline and perioperative characteristics on 3- and 8-year survival were also performed., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships which have, or could be perceived to have, influenced the work reported in this article., (© 2020 The Author(s).)
