A Tool to Assess Patient and Surrogate Knowledge About the POLST (Physician Orders for Life-Sustaining Treatment) Program

ContextIt is especially important that patients are well informed when making high-stakes, preference-sensitive decisions like those on the Physician Orders for Life-Sustaining Treatment (POLST) form. However, there is currently no way to easily evaluate whether patients understand key concepts when making these important decisions.ObjectivesTo develop a POLST knowledge survey.MethodsExpert (n = 62) ratings of key POLST facts were used to select items for a POLST knowledge survey. The survey was administered to nursing facility residents (n = 97) and surrogate decision-makers (n = 112). A subset (n = 135) were re-administered the survey after a standardized advance care planning discussion to assess the scale's responsiveness to change.ResultsThe 19-item survey demonstrated adequate reliability (α = 0.72.). Residents' scores (x = 11.4, standard deviation 3.3) were significantly lower than surrogate scores (x = 14.7, standard deviation 2.5) (P < 0.001). Scores for both groups increased significantly after administration of a standardized advance care planning discussion (P < 0.001). Although being a surrogate, age, race, education, cognitive functioning, and health literacy were significantly associated with higher POLST Knowledge Survey scores in univariate analyses, only being a surrogate (P < 0.001) and being white (P = 0.028) remained significantly associated with higher scores in multivariate analyses.ConclusionThe 19-item POLST Knowledge Survey demonstrated adequate reliability and responsiveness to change. Findings suggest the survey could be used to identify knowledge deficits and provide targeted education to ensure adequate understanding of key clinical decisions when completing POLST.

孟鲁司特治疗呼吸道合胞病毒毛细支气管炎症状及反复喘息疗效研究

背景　呼吸道合胞病毒（RSV）毛细支气管炎易出现反复喘息，且下呼吸道分泌物中半胱氨酸白三烯（CysLTs）水平升高。而孟鲁司特是一种白三烯受体拮抗剂，关于其治疗RSV毛细支气管炎症状的研究相对较少。目的　探讨孟鲁司特改善婴幼儿RSV毛细支气管炎后症状及减轻反复喘息发作的有效性和安全性。方法　2015年6月-2017年6月连续纳入在潍坊市妇幼保健院出院的RSV毛细支气管炎患儿，随机分为治疗组、对照组。Ⅰ期，治疗组：口服孟鲁司特颗粒（4 mg）12周，1次/d；对照组：口服安慰剂12周，1次/d。对两组无症状天数、个人日记评分进行评估。随访9个月（Ⅱ期），观察Ⅰ+Ⅱ期反复喘息人数和医疗资源应用情况等。依据意向性分析（ITT）原则，应用全分析集（FAS）分析数据。结果　共纳入研究对象186例，治疗组92例，对照组94例。治疗组完成Ⅰ期研究的患儿为89例，对照组为90例；治疗组完成Ⅰ+Ⅱ期的患儿为84例，对照组为86例。治疗组平均依从性为97.8%（7 560/7 728），对照组平均依从性为97.4%（7 690/7 896），两组患儿平均依从性比较，差异无统计学意义（χ2=3.16，P=0.07）。在Ⅰ期研究期间，两组无症状天数、日间无症状天数、夜间无症状天数、个人日记评分比较，差异均无统计学意义（P>0.05）。在整个研究过程中（Ⅰ+Ⅱ期），治疗组RSV毛细支气管炎喘息复发人数少于对照组（P<0.05），治疗组喘息患儿出现2次及以上喘息比例低于对照组（χ2=5.14，P=0.02）。Ⅰ+Ⅱ期研究期间治疗组医疗资源应用人数、β-受体激动剂应用人数、糖皮质激素应用人数、住院人数低于对照组（P<0.05）。在事后亚组分析中，治疗组有湿疹史与父母哮喘史的患儿中无症状天数〔（49.7±20.2）、（51.3±20.9）d〕多于对照组〔（36.3±20.4）、（37.8±19.3）d〕（t=2.19，P=0.03；t=2.24，P=0.03）。整个研究过程中没有患儿因不良反应退出研究，两组间胃肠道紊乱、皮疹、转氨酶升高发生率比较，差异均无统计学意义（χ2=0.23，P=0.63；χ2=0.03，P=0.86；χ2=0.15，P=0.69）。结论　口服孟鲁司特（4 mg）12周不能改善RSV毛细支气管炎患儿呼吸道症状，但能降低患儿反复喘息发作次数。口服孟鲁司特（4 mg）有一定效果且安全。     

Diet and nutrition against inflammatory bowel disease: Trick or treat(ment)?

Even if the relationships between nutrition and inflammatory bowel disease (IBD) remain underexplored, the current literature is providing, day by day, much more evidence on the effects of various diets in both prevention and treatment of such illnesses. Wrong dietary habits, together with other environmental factors such as pollution, breastfeeding, smoke, and/or antibiotics, are among the theoretical pathogenetic causes of IBD, whose multifactorial aetiology has been already confirmed. While some of these risk factors are potentially reversible, some others cannot be avoided, and efficient treatments become necessary to prevent IBD spread or recurrence. Furthermore, the drugs currently available for treatment of such disease provide low-to-no effect against the symptoms, making the illnesses still strongly disabling. Whether nutrition and specific diets will prove to effectively interrupt the course of IBD has still to be clarified and, in this sense, further research concerning the applications of such dietary interventions is still needed.

经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.     

肝段或肝叶切除术对肝内胆管结石再次手术效果的影响

目的对比不同术式对肝内胆管结石再次手术效果，探讨肝段或肝叶切除术的优势。 方法回顾性分析2011年8月至2014年8月收治的79例肝内胆管结石再次手术患者资料，依据术式不同分为肝段(叶)切除术组(甲组，n＝38)和非肝段(叶)切除术组(乙组，n＝41)两组。应用SPSS 19.0软件对所有临床数据进行统计学分析，手术相关指标等以( ±s)的形式表示，组间比较采用独立t检验；术后并发症发生情况及预后情况等计数资料以例(%)的形式表示，采用χ²检验；P<0.05差异有统计学意义。 结果两组患者术中出血量、手术时间及术后住院时间相比，差异无统计学意义(P>0.05)；甲组患者的术后并发症发生率5.3%(2/38)显著低于乙组22.0%(9/41)(P<0.05)；甲组残留结石发生率、症状复发率2.6%(1/38)、 0(0/41)均显著低于乙组17.1%(7/41)、 12.2%(5/41)(P<0.05)，差异有统计学意义(P<0.05)；但两组患者的病死率2.6%(1/38)和0(0/41)相比，差异无统计学意义(P>0.05)。 结论肝段(叶)切除术能够有效改善肝内胆管结石再次手术效果，值得推广。
