Patient satisfaction with occlusal scheme of conventional complete dentures

Occlusal scheme is a controversial topic that has been linked to patient satisfaction with conventional complete dentures (CCDs). This study aimed to compare the patient satisfaction with CCDs with four different occlusal schemes namely the lingualised occlusion (LO), buccalised occlusion (BO), fully bilateral balanced occlusion (FBBO) and partially group function occlusion (PGFO). In this clinical study, new CCDs were made for 121 patients; out of which, 97 patients (mean age of 57.87 ± 9.5 years) completed the 1-year follow-up. The CCD wearers were followed up at 1 month, 3 months and 1 year after CCD delivery. Data were collected via an interview and recorded in a checklist by a blinded examiner. The checklist included the demographic variables, the 19-item version of Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT), and seven 100-mm line visual analogue scales (VASs) to assess the items related to patient satisfaction. The Kruskal-Wallis and Friedman tests followed by post hoc tests were used to compare the variables among the 4 groups and between the 3 follow-ups. P-value ≤ .05 was considered statistically significant for all tests. The patients with BO presented higher satisfaction scores for comfort, stability and retention at the 1-year follow-up compared with PGFO. Both PGFO and FBBO groups had higher physical pain scores compared with BO and LO. The psychological discomfort scores of FBBO group were significantly higher than those in LO group. Pairwise comparisons revealed no significant differences in the general patient satisfaction and total OHIP-EDENT scores between the 4 groups. For most items, within-group analysis showed significant improvement of the satisfaction scores and reduction of domain scores over time.     

Thrombosis and infections of peripherally inserted central catheters in burn patients: A 3-year retrospective study and a systematic review

AimsPeripherally inserted central catheters (PICCs) are becoming common and effective in acute and critical care settings recently. Burn patients need special considerations because of restricted insertion sites, burn wounds, hyper coagulation, high infection rates and others. However, the safety of PICCs in burn patients are not well elucidated and no related protocol has been formed. This study aims to investigate the thrombosis and infections of PICCs in burn patients.MethodsThis was a single center retrospective study and a systematic review. All the burn patients with PICCs between January 1, 2018 and December 31, 2020 were included. A systematic search of Medline, PubMed, EMBASE and Web of Science was performed from inception to 4 June 2021 following PRISMA guidelines. Upper extremity vein thrombosis (UEVT) and central line-associated bloodstream infection (CLABSI) were the main outcome.ResultsA total of 85 successful PICCs in 78 patients were included. Most patients were male (79.5%), adults(80.8%) and injured by flame(74.4%). The mean TBSA was 50.3% and 76.9% of patients had TBSA more than 30%. Most PICCs were punctured once (60.0%) and inserted less than 30 days after injury (80.0%) through basilar vein (70.6%). The overall line days were 2195 days and the mean line days was 25.8 ± 18.3 days. Six PICCs were complicated by UEVT (7.1%) in 21.2 ± 17.3 days after insertion. Patients with UEVT had significantly higher rate of bacteremia and later insertions than those without UEVT. One patient developed CLABSI and the CLABSI rate was 1.2% and 0.5 per 1000 line days. Six PICCs had catheter colonization. No significant risk factors were identified. Five articles involving 293 patients and 319 PICCs were ultimately evaluated in systematic review. The overall incidence of UEVT was 3.2% and CLABSI was 6.9% in burn populations.ConclusionPICCs in burn patients had acceptable incidence of UEVT and CLABSI with relative long line durations. A standardized PICC guideline for burn patients is required to further improve the feasibility and safety of PICCs.     

TACE 术前天冬氨酸氨基转移酶与淋巴细胞比值对原发性肝癌并门脉癌栓患者预后预测的价值

目的 探讨肝动脉化疗栓塞（transcatheter arterial chemoembolization，TACE）术前天冬氨酸氨基转移酶与淋巴细胞比值（aspartate aminotransferase to lymphocyte ratio index，ALRI）在原发性肝癌并门脉癌栓（primary liver cancer-portal vein tumor thrombosis，PLC-PVTT）患者预后预测中的价值。方法 选取2013年11月21日至2018年8月22日于广西医科大学附属肿瘤医院接受TACE治疗的175例PLC-PVTT患者为研究对象。采用时间依赖性ROC曲线确定ALRI的最佳临界值。采用Cox 回归模型分析总生存期（overall survival，OS）的独立预测因素，Kaplan-Meier法计算生存率。结果 ROC曲线显示，ALRI的最佳临界值为49.37，对应曲线下面积为0.71。Kaplan-Meier分析显示，ALRI>49.37的患者OS较ALRI≤49.37的患者短（P=0.003）。Cox 回归分析结果显示，ALRI>49.37、行1次以上TACE治疗、Child-Pugh分级B级、凝血酶原时间≥13 s是患者TACE术后OS的独立危险因素（均P＜0.05）。结论 TACE术前ALRI>49.37是PLC-PVTT患者OS的独立危险因素。
