ObjectiveTo compare the predictive value of six thrombotic risk assessment scales, including Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT, for the deep venous thrombosis (DVT) of lower extremity in patients with gastrointestinal tumors. MethodsThe patients with gastrointestinal tumors who received surgical treatment in the General Surgery Department of Lanzhou University Second Hospital from March 2023 to October 2023 were collected. The risk of DVT on day 3 after surgery for the patient with gastrointestinal tumors was prospectively evaluated using the Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT assessment scales. And the DVT was detected by ultrasound examination. The pionts of six thrombotic risk assessment scales were compared between the patient with DVT and without DVT based on the ultrasound examination results. The predictive value of the six thrombotic risk assessment scales for the lower extremity DVT in the patients with gastrointestinal tumors was evaluated by the area under receiver operating characteristic curve (AUC). ResultsA total of 108 patients who met the criteria, including 71 males and 37 females, were enrolled, age ranged from 18 to 85 years old, (58.3±11.2) years old. Fourty-two cases (38.9%) of DVT occurred. The age of patients with DVT was older than that of patients without DVT (P<0.05), but there were no statistical differences in the gender, body mass index, tumor location, comorbidities, and so on (P>0.05). The points of Autar, Padua, and Caprini in the patients with DVT were higher than those in the patients without DVT (P<0.05), while there were no statistical differences in the points of Wells, Khorana, and COMPASS-CAT between the two (P>0.05). The AUC for differentiating the occurrence of DVT in the patients with gastrointestinal tumors using the Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT assessment scales were 0.907, 0.548, 0.636, 0.627, 0.589, and 0.535, respectively; The sensitivities were 97.6%, 14.3%, 52.4%, 83.3%, 47.6%, and 21.4%; The specificities were 2.4%, 85.7%, 47.6%, 16.7%, 52.4%, and 78.6%, respectively. ConclusionAccording to the abilities of Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT to distinguish the occurrence of DVT in patients with gastrointestinal tumors after surgery, only the Autar evaluation scale is found to be more effective, while the other five evaluation scales are generally able to distinguish the occurrence of DVT.
With the increasingly prominent contradiction between limited health resources and the growing population, priority setting of health research, as a response, has received widespread attention from health systems worldwide. As the results of priority setting at different levels increase year by year, some questions in the results reporting are also constantly emerging. For example, the process of producing the results is vague, too dependent on individual subjective judgment, the participation of individual stakeholder groups is limited or lack of voice, unable to identify potential conflicts of interest, and so on. It does not only seriously affect the effectiveness and rationality of the results themselves, but also create intangible obstacles to their promotion and adoption. In 2019, BMC Medical Research Methodology published ‘Reporting guideline for priority setting of health research (REPRISE)’, which makes uniform specifications for more comprehensive and consistent reporting of results in priority areas. This paper interpreted the background, formulation process and key contents of the REPRISE guideline, with an aim to promote the application of the reporting guideline in China.
ObjectiveTo systematically review the studies on the clinical comprehensive evaluation system of drugs at home and abroad. MethodsThe PubMed, EMbase, Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect the literature and policy documents of the clinical comprehensive evaluation system of drugs from inception to October 31, 2022. The evaluation organization, evaluation perspective, application scope, domains and criteria were sorted out, and the evaluation of different types of drugs was analyzed in detail. ResultsA total of 101 clinical comprehensive evaluation systems of drugs were included. The publishing time was from 2009 to 2022, and the number of published articles increased. The first author mainly came from 26 countries, including China (n=34), Canada (n=11), the United States (n=10), and Spain (n=10). Forty-seven articles reported the evaluation perspective. All evaluation systems could be used for drug evaluation, of which 43 could be used as universal evaluation tools, and 58 could be used for the evaluation of specific drugs, mainly including anti-tumor drugs (n=15), orphan drugs (n=10) and traditional Chinese medicine (n=7). The number of evaluation domains varied from 2 to 22, and the number of criteria varied from 4 to 56. Among them, economics (n=73), effectiveness (n=72), safety (n=54), disease demand/burden (n=34), and innovation (n=24) were the most frequent evaluation domains. ConclusionThe research on clinical comprehensive evaluation of drugs at home and abroad has grown up. During the implementation of clinical comprehensive evaluation of Chinese patent medicine, it is necessary to clarify the evaluation perspective, define the evaluation scope, and determine the evaluation domains.
Health Technology Assessment International (HTAi), in conjunction with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), initiated a joint Task Force and published guideline and a checklist for deliberative processes for health technology assessment (HTA). Currently, there is a lack of guidance for designing and implementing deliberative processes of HTA in China, so this paper performs a detailed interpretation of the guideline and checklist, with a view to providing a reference for China's HTA and deliberative process, in order to promote the dissemination and application of the HTA methodology, and advance the construction of domestic HTA deliberative processes capacity and institutional mechanism.
ObjectiveThe abnormal autophagy fluxis involved in the pathophysiological process of drug-resistance temporal lobe epilepsy (TLE).Hippocampal sclerosis (HS) is the main pathological type of drug-resistance TLE.Different subtypes of HS have various prognosis, etiology and pathophysiology.However, whether theabnormal block ofautophagy flux involved in this process has not been reported.This study proposed a preliminary comparison of autophagy fluxin typical and atypical HS to investigate the potential pathogenesis and drug-resistance mechanism of atypical HS. MethodsSurgical excision of hippocampal and temporal lobe epilepsy foci were performed in 17 patients with drug-resistance TLE.Patients were grouped according to the HS classification issued by International League Against Epilepsy in 2013.The distribution and expression of LC3B, beclin-1 and P62 were detected by immunohistochemistry and Western blot in each group. ResultsLC3B, beclin-1 and P62 are mainly expressed in neuronal cytoplasm, which is consistent with previous reports.Taking β-actin as internal reference, we found that LC3B and Beclin-1, the downstream products of autophagy flux, have increased significantly (P < 0.01) in the atypical HS group compared to typical HS group.However, the autophagy flux substrate P62 has no difference between the groups.This result suggested that compared with the typical HS group, atypical HS group had autophagy substrate accumulation and autophagy flux abnormal block.Besides, we found that glyceraldehycle-3-phosphate dehydrogenase(GAPDH) was significantly different between the two groups (P=0.003). ConclusionThere is abnormal phenomenon of autophagy flux in atypical HS, and GAPDH elevation may be involved in its mechanism, which might provide new targets and ideas for future treatment of atypical HS.
ObjectiveTo explore the clinical efficacy of two procedures in thoracoscopic anterior mediastinal tumor resection. MethodsA retrospective study was conducted on patients who underwent thoracoscopic anterior mediastinal tumor resection at the Department of Thoracic Surgery, the 910th Hospital of Joint Logistics Support Force from October 2016 to January 2024. Patients were divided into two groups according to the surgical approach: a modified approach group (bilateral intercostal ports+two subcostal ports) and a classic subxiphoid approach group (one subxiphoid port+two subcostal ports). Perioperative data and postoperative improvement of myasthenia gravis (MG) subgroup were compared between the two groups. ResultsA total of 55 patients were included, including 27 males and 28 females with a mean age of (49.4±15.1) years. There were 23 patients in the modified approach group and 32 patients in the classic subxiphoid approach group. The modified approach group had shorter operation time [(129.0±20.5) min vs. (148.9±16.7) min, P<0.001], less intraoperative blood loss [(63.0±16.6) mL vs. (75.0±10.8) mL, P<0.001], shorter postoperative drainage tube removal time [(3.1±0.4) d vs. (3.9±0.6) d, P<0.001] and shorter postoperative hospital stay [(4.2±0.4) d vs. (5.0±0.6) d, P<0.001), and lower proportion of intraoperative cardiac dysfunction [4 (17.4%) vs. 14 (43.8%), P=0.040]. There was no statistical difference in maximum diameter of tumor resected [(4.5±1.7) cm vs. (4.0±0.9) cm, P=0.193] and postoperative drainage volume [(396.4±121.5) mL vs. (399.9±161.3) mL, P=0.932]. There was 1 patient of perioperative collateral injury in the modified approach group (pericardial injury), and 6 patients in the classic subxiphoid approach group (1 patient of diaphragm injury, 1 patient of liver contusion, 4 patients of pericardial injury). There was no statistical difference in pain scores at 24 h, 48 h and 72 h after surgery (P>0.05). The postoperative improvement of MG symptoms in the modified approach group was better than that in the classic subxiphoid approach group at 1 year after surgery (complete stable remission rate: 77.8% vs. 50.0%; effective rate: 100.0% vs. 91.6%). No conversion to open chest surgery occurred in either group, and there were no postoperative rehospitalizations or deaths related to surgery within 30 days after surgery in both groups. ConclusionThe modified approach is safe and controllable with more open surgical field and more reliable complete resection range than the classic subxiphoid approach group.
