2型糖尿病患者基础胰岛素剂量自我调整方案的随访管理

目的评价2型糖尿病患者基础胰岛素剂量自我调整方案的随访管理效果。方法将849例2型糖尿病患者按住院时间分为对照组(423例)和观察组(426例)。对照组采用由医生门诊调整胰岛素剂量的常规方案,观察组由糖尿病专科护士依据医生制定的血糖调整方案卡对患者自我调整胰岛素剂量进行全程随访管理。干预12周后比较两组血糖指标、糖尿病知识水平、授权能力、自我管理能力。结果观察组血糖控制水平显著优于对照组(P0.05),两组低血糖发生率差异无统计学意义(P0.05);观察组糖尿病知识水平、授权能力、自我管理能力显著优于对照组(P0.05,P0.01)。结论糖尿病专科护士对患者自我调整基础胰岛素剂量进行全程随访管理在血糖控制方面安全有效,且能提高患者自我管理能力和授权能力。     

Temporal Trends of Women Enrollment in Major Cardiovascular Randomized Clinical Trials

Background

Although it is known that women do not participate in trials as frequently as men, there are limited recent data examining how women recruitment has changed over time.

Evolving Radiotherapy Techniques in Paediatric Oncology

Aims

Childhood cancer is rare and survival of childhood cancer has increased up to 80% at 5 years after diagnosis. Radiotherapy is an important element of the multimodal treatment concept. However, due to growing tissue, children are particularly sensitive to radiation-related side-effects and the induction of secondary malignancies. However, radiotherapy techniques have continuously progressed. In addition, modern treatment concepts have been improved in order to minimise long-term effects. Today, radiotherapy is used for various tumour types in childhood, such as sarcomas and tumours of the central nervous system.

肝脏CT动态增强扫描非刚性对位减影技术的质量评价

目的利用血管减影前后的吻合程度，探讨非刚性对位减影技术在肝脏CT动态增强检查中的质量评价。 方法收集2018年12月至2019年2月于中山大学附属第一医院行肝脏CT动态增强检查的50例患者资料，使用非刚性对位减影技术获得减影图像，对减影前后的图像质量进行评价，定性评价包括图像伪影情况及解剖错配程度，定量评价测量各血管（腹主动脉、肝右动脉、肝左动脉、门静脉主干、门静脉右支、门静脉左支）减影前后在动脉晚期、门静脉晚期的CT值。采用混合线性效应模型及拟合方程评估减影前后各血管的CT值曲线拟合程度。 结果减影后图像均无明显解剖结构错配导致的伪影，3名测量者一致性较高（ICC=0.844，P<0.001）。减影技术一定程度上会降低各血管的CT值，与强化分期不存在交互作用。无论是在动脉晚期还是门静脉晚期，减影前后各血管CT值走势一致，CT值变化曲线吻合。 结论非刚性对位减影技术可轻松实现肝脏CT动态增强检查的图像减影，并获得良好的图像质量。     

机器人辅助ALPPS手术治疗右肝巨块型肝癌

正【内容简介】ALPPS全称为联合肝脏离断和门静脉结扎的二步肝切除术,一期手术离断或分割肝实质,结扎门静脉分支;二期手术彻底离断病肝并取出。此术式主要针对因肝脏肿瘤占位过大、常规切除会导致剩余肝脏体积(FLR)不够且需要行扩大肝切除术的肝脏恶性肿瘤而采用的手术方法。其目的为通过一期手术促进健侧肝脏增生,从而为二期手术施行根治性切除创造有利条件。该视频病例采用机器人辅助进行一期手术,开腹     

高危原发前列腺胃肠道外间质瘤诊疗体会及文献复习

目的探讨前列腺原发胃肠道外间质瘤诊治要点。 方法回顾性分析我院2017年9月诊治的1例高危原发性前列腺胃肠道外间质瘤临床病理特征资料、随访情况，总结现有文献讨论总结本病诊治心得。 结果65岁男性，因"前列腺电切术后2年，反复血尿3个月余"入院。术前MRI考虑为来源不清的盆腔巨大实性占位（115 mm×105 mm×85 mm），经直肠穿刺诊断为梭形细胞来源的肿瘤。行盆腔肿瘤切除+膀胱前列腺腺切除+盆腔淋巴结清扫术+Bricker术。术后病理提示为前列腺原发胃肠道外间质瘤[CD117（+）；Dog1（+）；CD34（+）；PSA（+）；AR（+）；P504s（+）；Ki-67（2%）]。术后肿瘤组织全外显子测序提示为C-Kit基因（Exon 11 p.Q556-V560del）存在明显临床意义突变，筛选靶向药物甲磺酸伊马替尼+比卡鲁胺（PSA平稳后停用）口服，术后随访18个月无肿瘤复发及不良并发症。 结论前列腺原发胃肠道外间质瘤罕见，需与前列腺其他良恶性肿瘤相鉴别诊断。全外显子测序了解其发病高危基因，同时筛选药物辅助治疗可使患者生存获益。     

两种保留自主神经D3根治术治疗中低位直肠癌的安全性及生存质量比较

目的比较腹腔镜保留自主神经D3根治术与开腹术治疗中低位直肠癌的安全性及生存质量差异。 方法回顾性分析2015年6月至2017年8月间84例低位直肠癌患者资料，根据手术方式不同分为腹腔镜组(n＝46)和开腹组(n＝38)，应用SPSS21.0软件完成数据分析。手术相关指标采用( ±s)表示，独立样本t检验；并发症发生率、复发率及生存率等指标采用χ²检验；P<0.05为差异有统计学意义。 结果腹腔镜组患者的手术时间长于开腹组(P<0.05)，而术中出血量、住院时间、尿管保留时间、肛门排气时间均短于开腹组(均P<0.05)。腹腔镜组术后并发症总发生率为6.5%低于开腹组的26.3%(χ²＝4.6517，P<0.05)。两组患者1年局部复发率及生存率差异均无统计学意义(均P>0.05)。腹腔镜组患者术后10 d排尿功能、术后2个月勃起功能、术后2个月射精功能均优于开腹组(均P<0.05)。 结论腹腔镜保留自主神经D3根治术治疗中低位直肠癌安全性较高，复发率及生存率与开腹术相当，并能显著提高患者的生存质量，值得推广应用。     

Derivation and Validation of a Model to Predict 30-Day Readmission in Surgical Patients Discharged to Skilled Nursing Facility

ObjectivesTo identify factors associated with 30-day all-cause readmission rates in surgical patients discharged to skilled nursing facilities (SNFs), and derive and validate a risk score.DesignRetrospective cohort.Setting and participantsPatients admitted to 1 tertiary hospital's surgical services between January 1, 2011, and December 31, 2014 and subsequently discharged to 110 SNFs within a 25-mile radius of the hospital. The first 2 years were used for the derivation set and the last 2 for validation.MethodsData were collected on 30-day all cause readmissions, patient demographics, procedure and surgical service, comorbidities, laboratory tests, and prior health care utilization. Multivariate regression was used to identify risk factors for readmission.ResultsDuring the study period, 2405 surgical patients were discharged to 110 SNFs, and 519 (21.6%) of these patients experienced readmission within 30 days. In a multivariable regression model, hospital length of stay [odds ratio (OR) per day: 1.03, 95% confidence interval (CI) 1.02-1.04], number of hospitalizations in past year (OR 1.24 per hospitalization, 95% CI 1.18-1.31), nonelective surgery (OR 1.33, 95% CI 1.18-1.65), low-risk service (orthopedic/spine service) (OR 0.32, 95% CI 0.25-0.42), and intermediate-risk service (cardiothoracic surgery/urology/gynecology/ear, nose, throat) (OR 0.69, 95% CI 0.53-0.88) were associated with all-cause readmissions. The model had a C index of 0.71 in the validation set. Using the following risk score [0.8 × (hospital length of stay) + 7 × (number of hospitalizations in past year) +10 for nonelective surgery, +36 for high-risk surgery, and +20 for intermediate-risk surgery], a score of >40 identified patients at high risk of 30-day readmission (35.8% vs 12.6%, P < .001).Conclusions/ImplicationsAmong surgical patients discharged to an SNF, a simple risk score with 4 parameters can accurately predict the risk of 30-day readmission.
