ObjectiveTo explore the clinical significance of detecting serum intact parathyroid hormone (iPTH) and drainage fluid parathyroid hormone (dPTH) after thyroidectomy in forecasting parathyroid function.MethodsThe clinical data of 95 thyroidectomy patients in the same treatment group from March 2018 to September 2018 were retrospectively analyzed, which in the Department of Thyroid-Breast Surgery, the Second Affiliated Hospital of Kunming Medical University. According to the surgical method, the patients were divided into 3 groups: isthmus and unilateral thyroidectomy (partial resection group, n=33), total thyroidectomy (total resection group, n=33) and total thyroidectomy and central lymph node excision (radical resection group, n=29). The negative pressure drainage tube was placed in the operative area. The iPTH and serum calcium were detected before and the first day after operation. The dPTH was detected in the first day and the second day after operation. Serum calcium, iPTH and dPTH were statistically analyzed.ResultsThere were no significant differences in operative time, hospital stay and blood loss between the total resection group and the radical resection group (P>0.05), but the partial resection group were all less than the other two groups (P<0.01). On the first day after operation, the iPTH in the three groups were lower than that before operation, and the iPTH was significantly decreased in the total resection group and the radical resection group, with statistically significant difference (P<0.05). The dPTH in the three groups were significantly increased on the first and second day after operation (P<0.05), but there was no statistically significant difference between the three groups (P>0.05). There was no statistically significant difference in serum calcium between the three groups on the first day after operation (P>0.05).ConclusionsThe levels of iPTH, dPTH and serum calcium after thyroidectomy can comprehensively forecast the parathyroid function. Preventive calcium supplementation can reduce the occurrence of postoperative symptomatic hypocalcemia, which is conducive to the recovery of parathyroid function.
Objective To explore the long-term trends and epidemiological characteristics of the disease burden of tetanus in China over the past 30 years and to predict its disease burden in 2050, in order to comprehensively assess the overall disease burden of tetanus in China. Methods Leveraging the methods and findings of the Global Burden of Disease Study 2021, we provided a detailed description of the disease burden of tetanus in China based on key indicators such as prevalence, incidence, mortality, disability-adjusted life years, years lived with disability, and years of life lost due to premature mortality. Joinpoint regression analysis, age-period-cohort analysis, decomposition analysis, and Bayesian age-period-cohort models were employed to further elucidate the epidemiological characteristics of tetanus and predict its disease burden in China by 2050. Results From 1990 to 2021, the overall disease burden of tetanus in China exhibited a significant year-by-year decline. The primary demographic group bearing the burden of tetanus in China had gradually shifted from newborns to middle-aged and elderly individuals, with males being more affected than females. Decomposition analysis indicated that epidemiological change was a significant factor contributing to tetanus in China, while the impacts of population and aging were relatively minor. According to predictions from the Bayesian age-period-cohort model, by 2050, only the prevalence rate was expected to slightly increase, while all other indicators were projected to decline and remain at low levels. Conclusion The disease burden of tetanus in China decreased from 1990 to 2021. In subsequent prevention efforts, newborns and middle-aged and elderly individuals should be prioritized as targets for prevention and control to maintain the disease burden of tetanus at a low level.
