AbstractTooth extraction has been avoided since it has been considered a major risk factor for medication-related osteonecrosis of the jaw (MRONJ). However, MRONJ may also develop from tooth that is an infection source. This study aimed to clarify whether tooth extraction is a risk factor for the development of MRONJ in cancer patients receiving bone-modifying agents (BMAs). This retrospective observational study included 189 patients (361 jaws) from two hospitals. The risk factors of MRONJ were identified by comparing patient characteristics between those who did and did not develop MRONJ. Furthermore, the effect of tooth extraction during BMA therapy was analyzed after adjusting for confounding factors using the propensity score matching method. MRONJ occurred in 33 patients jaws. A longer duration of BMA administration, fewer number of teeth, presence of symptoms of local infection, and infected teeth were independent risk factors of MRONJ. However, tooth extraction during BMA therapy did not increase the risk. Propensity score matching analysis showed that tooth extraction significantly lowered the risk of MRONJ development. Teeth that can be an infection source increases the risk of MRONJ, and thus, they need to be extracted even during BMA administration.

Abstract Background Delayed post-polypectomy bleeding (PPB) is a major complication of polypectomy. The effect of prophylactic hemoclipping on delayed PPB is uncertain. The aim of this study was to evaluate the effectiveness of prophylactic hemoclipping and identify the risk factors of delayed PPB. Methods Patients with polyps sized 6 to 20 mm underwent snare polypectomy from 2015 to 2017 were retrospectively reviewed. The patients with prophylactic hemoclipping for delayed PPB prevention were included in the clipping group, and those without prophylactic hemoclipping were included in the non-clipping group. The incidence of delayed PPB and time to bleeding were compared between the groups. Multivariate analysis was used to identify the risk factors of delayed PPB. Propensity score matching was used to minimize potential bias. Results After propensity score matching, 612 patients with 806 polyps were in the clipping group, and 576 patients with 806 polyps were in the non-clipping group. There were no significant differences in the incidence of delayed PPB and days to bleeding between two groups (0.8% vs 1.3%, p = 0.4; 3.4 ± 1.94 days vs 4.13 ± 3.39 days, p = 0.94). In the multivariate analysis, the polyp size [Odds ratio (OR):1.16, 95% confidence interval (CI):1.01–1.16, p = 0.03), multiple polypectomies (OR: 4.64, 95% CI:1.24–17.44, p = 0.02) and a history of anticoagulant use (OR:37.52, 95% CI:6.49–216.8, p < 0.001) were associated with delayed PPB. Conclusions In polyps sized 6 to 20 mm, prophylactic hemoclip placement did not decrease the risk of delayed PPB. Patients without risk factors including multiple polypectomies and anticoagulant use are no need to performing prophylactic hemoclipping.

Background/Aims: Postoperative mortality and morbidity rates after hepato-pancreato-biliary (HPB) surgery remain high, and the number of elderly patients requiring such surgery has been increasing. This study aimed to investigate postoperative outcomes of complex HPB surgery for elderly patients. Methods: We retrospectively reviewed perioperative data of 721 patients who underwent complex HPB surgery between 2010 and 2015. The patients were divided into 2 groups: elderly (≥75 years) and non-elderly (< 75 years). Surgical outcomes of both groups were compared after propensity score-matching analysis. Subsequently, risk factors for serious postoperative morbidity were identified by multivariate analysis. Results: Before matching, the elderly group (n = 170) had more comorbidities, such as cardiovascular and renal disease, than the non-elderly group (n = 551). Matching yielded elderly (n = 170) and non-elderly groups (n = 170) with similar preoperative backgrounds. The mortality and morbidity rates did not differ significantly between the groups. In multivariate analyses, operative time (OR 1.79; p = 0.005) and blood loss (OR 1.66; p = 0.03) were identified as independent risk factors for serious postoperative morbidity, whereas older age did not have a predictive impact (OR 1.16; p = 0.52). Conclusions: Although elderly ­patients had more comorbidities and higher incidences of postoperative mortality and several complications before matching, their postoperative outcomes were equivalent to those of non-elderly patients after matching.

Abstract Objective To explore the factors affecting the timing and prognosis of early tracheostomy(within 7 days after tracheal intubation) in patients with multiple rib fractures. Methods A retrospective analysis of the medical history of 222 patients with multiple rib fractures who were admitted to the department of emergency intensive care unit(EICU) of the affiliated hospital of Yangzhou University from February 2015 to October 2019 underwent early tracheostomy. According to the time from tracheal intubation to tracheostomy after admission, the patients were divided into two groups: early tracheostomy group (within 7 days after tracheal intubation,ET) and late tracheostomy group (after the 7th day, LT). The propensity score matching analysis technique was used to compare the differences between the two groups in a 1:1 ratio. Results A total of 222 patients were enrolled, with 118 in the ET group and 104 in the LT group. After matching, 87 in the ET group and 87 in the LT group. The proportion of acute respiratory distress syndrome(ARDS)[59(67.8%)], the volume of pulmonary contusion (VPC)[33.8±11.4], and number of total rib fractures (NTRF)[10.8±2.7] in the ET were significantly higher than those in the LT group, P<0.05. Binary Logistic regression analysis showed that ARDS[OR=3.740, 95%CI(1.441, 9.711)], VPC[OR=1.087, 95%CI(1.052, 1.124)], and NTRF [OR=1.775, 95%CI(1.439, 2.188)] were independent risk factors for ET.The Pearson analysis showed that VPC and NTRF had significant correlation(R=0.369, P=0.01), ARDS and VPC had low degree correlation(R=0.179, P=0.018), while ARDS and NTRF had no significant correlation(R=0.132, P=0.110). Receiver operating characteristic(ROC)curve analysis showed that the area under VPC and NTRF curves [0.832(95%CI: 0.770~0.893),0.804(95%CI: 0.740~0.868)] were significantly more than the number of rib fractures(NFR), glasgow coma scale(GCS), and injury severity score(ISS), P<0.05. COX regression analysis showed that patients with underwent ET survived significantly better than the LT, P<0.05. Conclusions We found that ARDS, VPC, and NTFR were independent risk factors for ET; VPC ≥ 23.9% and (or) NTRF ≥ 8.5 could be used as predictors of ET in patients with multiple rib fractures. There was a linear relationship between NTRF and VPC. ET might benefit patients with multiple rib fractures.
