The direct injury models have a minimum observation period of 2 months and a maximum of 32 wk. All direct injury models were successful in causing disk degeneration, and the greater the number of interventions, the greater the degree of disk degeneration caused. The observation period for the indirect injury models varied from 4 wk to 70 wk. Of the 9 studies, only one study was unsuccessful in inducing disk degeneration, and this was the first animal study in this research to attempt to intervene on the endplate to cause disk degeneration.CONCLUSIONThe damage to the direct injury model is more immediate and controllable in extent and can effectively lead to disk degeneration. The indirect injury models do not directly damage the endplate structure, making it easier to observe the physiological and pathological condition of the endplate and associated structures of the disk. None of them can completely simulate the corresponding process of endplate injury-induced disk degeneration in humans, and there is no uniform clinical judgment standard for this type of model.

The quality and safety of surgery for pancreatic cancer have improved in recent years with increasing adoption of minimally invasive techniques and surgical adjuncts. Systemic chemotherapy has also evolved to impact survival. It is now increasingly being utilized in the neoadjuvant setting, often with concomitant radiation. Increased utilization of genomic testing in metastatic pancreatic cancer has led to better understanding of their biology, thereby allowing clinicians to consider potential targeted therapies. Similarly, targeted agents such as PARP inhibitors and immune checkpoint- inhibitors have emerged with promising results. In summary, pancreatic cancer remains a disease with poor long-term survival. However, recent developments have led to improved outcomes and have changed practice in the past decade.

This study aimed to determine whether lactate dehydrogenase (LDH) is associated with an increased risk of 30-day readmission in gastric cancer.</p><p><strong>Methods: </strong>We performed a retrospective study of patients who underwent radical gastrectomy for gastric cancer at our institution between July 2014 and May 2018. Balanced cohorts were created by propensity score matching (PSM) with a 1:1 ratio to generate the elevated LDH (ELDH) group (n = 151) and the low LDH group (Control) (n = 302). To determine the incidence, causes, and risk factors of 30-day readmission, subgroup analyzes were performed and used to develop an efficient prediction model.</p><p><strong>Results: </strong>A total of 788 patients met the criteria to be included in the study. The cutoff value for serum LDH was 215.5. After PSM, a total of 302 patients were matched in pairs (ELDH group, n = 151, Control group, n = 151). ELDH levels had a higher risk of readmission (p = 0.005, Odds ratio 3.768, 95% confidence interval 1.493-9.510). The pre-match 30-day readmission rate was 7.2 percent, and common causes of post-match readmission included infection-related symptoms, gastrointestinal symptoms, and gastrointestinal bleeding.</p><p><strong>Conclusions: </strong>Patients with preoperative ELDH levels, postoperative complications, and high preoperative American Society of Anesthesiologists Scores had a higher risk of readmission 30 days after surgery.</p>","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":" ","pages":"2172488"},"PeriodicalIF":1.9,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10692132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
