1401例超长住院日患者分布与影响因素分析

目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。     

白内障术后生物学参数变化及IOL计算公式的准确性研究

目的：运用新型光学生物测量仪IOL Master 700测量白内障超声乳化手术前后眼部生物学参数的变化，并探讨人工晶状体(IOL)屈光度数计算公式的选择。

方法：前瞻性研究。收集2021-01/06在苏州大学附属第一医院就诊的白内障患者52例57眼。术前和术后3mo使用IOL Master 700完成眼轴长度(AL)、前房深度(ACD)、角膜曲率(Km)的测量并分析。对不同IOL公式计算时预留的目标屈光值与术后3mo全自动验光仪实际屈光值结果进行比较并分析。

结果：手术前后测量的AL平均值分别为24.20±1.86、24.09±1.86mm，术后AL缩短了0.11mm； ACD值分别为3.08±0.44、4.55±0.36mm(P<0.001)，术后ACD加深1.49mm； Km值分别为44.14±1.86、44.14±1.82D(P>0.05)。术前选用Barrett Universal Ⅱ公式所测结果的屈光误差最小，其次是Holladay Ⅱ及SRK/T公式，Holladay Ⅰ公式所测结果的误差最大(P<0.05)。

结论：白内障术后AL缩短以及ACD加深，度数测算时可考虑增加0.1mm的校正因子。IOL屈光度数计算公式中Barrett Universal Ⅱ公式预测性最佳，其次是Holladay Ⅱ及SRK/T公式。

Prognostic significance of tumor multifocality on outcomes in patients with upper tract urothelial carcinoma after radical nephroureterectomy: A cohort study

To identify the prognostic impact of tumor multifocality on upper tract urothelial carcinoma (UTUC) outcomes in patients treated with radical nephroureterectomy (RNU). Study included 342 consecutive patients with UTUC. Tumor multifocality was defined as the synchronous presence of 2 or more pathologically confirmed tumors in any upper urinary tract location. Cox regression analyses were used to address recurrence-free (RFS) and cancer-specific survival (CSS) estimates. Tumor multifocality was significantly associated with a history of previous non-muscle invasive bladder cancer (P < 0.001), tumor size (P < 0.001), gender (P = 0.009), tumor location (P = 0.005), and anemia (P = 0.01). The Kaplan–Meier method showed that tumor multifocality was significantly associated with worse recurrence-free survival (P < 0.001, log rank). Using multivariate analysis, tumor multifocality (HR, 2.86; 95% CI, 2.06 – 3.99; P < 0.001) was independently associated with recurrence free survival. During the follow-up, a total of 128 (37.4%) patients died, including 92 (28.2%) from UTUC. However, tumor multifocality was not associated with CSS (HR, 1.29; 95% CI, 0.89 – 1.96; P = 0.21) in univariate Cox regression analyses. Tumor stage (HR, 11.1; 95% CI, 3.64 – 33.8; P < 0.001), lymph node status (HR, 2.04, 95% CI, 1.05 – 3.94; P = 0.03) and preoperative anemia (HR, 3.50, 95% CI, 2.02 – 6.08; P < 0.001) were the only independent predictors associated with worse cancer-specific survival. Tumor multifocality is an independent prognostic factor of disease recurrence in patients treated with RNU for UTUC. Tumor multifocality is unable to predict cancer specific survival in a single-center series of consecutive patients who were treated with RNU.     

MicroRNA-199-3p up-regulation enhances chondrocyte proliferation and inhibits apoptosis in knee osteoarthritis via DNMT3A repression

Trajectory of adherence to home rehabilitation among older adults with hip fractures and cognitive impairment

This study aimed to identify different trajectories of adherence to home rehabilitation for older adults with hip fracture and cognitive impairment, to examine associations between different adherence trajectories and postoperative recovery outcomes, and to explore the predictors of adherence trajectories. Group-based trajectory modeling showed two adherence trajectories: low (39.06%) and high (60.94%) adherence. The high adherence group had better activities of daily living (β=11.77, p<.001), instrumental activities of daily living (β=0.56, p<.01), femoral muscular strength (β=3.35, p<.01) on the fractured side and quality of life (β=-0.81, p=.02) than the low adherence group. Participants who established exercise habits (OR=6.49, p<.01) and consulted a physical therapist (OR=4.29, p=.03) during hospitalization were more likely to be in the high adherence group.
