Personal comorbidities and their subsequent risks for liver,gallbladder and bile duct cancers

Many environmental risk factors for hepatobiliary cancers are known but whether they are associated with specific cancer types is unclear. We present here a novel approach of assessing standardized incidence ratios (SIRs) of previously diagnosed comorbidities for hepatocellular carcinoma (HCC), gallbladder cancer (GBC), cholangiocarcinoma (CCA) and ampullary cancer. The 13 comorbidities included alcohol and nonalcohol related liver disease, chronic obstructive pulmonary disease, gallstone disease, viral and other kinds of hepatitis, infection of bile ducts, hepatic and other autoimmune diseases, obesity and diabetes. Patients were identified from the Swedish Inpatient Register from 1987 to 2018, and their cancers were followed from 1997 onwards. SIRs for HCC were 80 to 100 in men and women diagnosed with hepatitis C virus and they were also >10 in patients diagnosed with hepatitis B virus, other kind of hepatitis, hepatic autoimmune disease and nonalcohol related liver disease. Many of these risks, as well as alcohol related liver disease, were either specific to HCC or were shared with intrahepatic CCA. For GBC, CCA and ampullary cancer infection of bile ducts was the main risk factor. Gallstone disease, nonhepatic autoimmune diseases and diabetes were associated with all hepatobiliary cancers. The limitations of the study include inability to cover some rare risk factors and limited follow-up time. Many of the considered comorbidities are characterized by chronic inflammation and/or overt immune disturbance in autoimmune diseases. The results suggest that local chronic inflammation and a related immune disturbance is the carcinogenic trigger for all these cancers.

目的:探讨早产儿消化道穿孔的病因，分析影响早产儿消化道穿孔短期预后不良的危险因素。方法:回顾性分析山西省 儿童医院新生儿外科2015年1月—2021 年5月诊治的89 例早产儿消化道穿孔的临床资料。根据术后3 个月时结局分为生存 组和预后不良组。比较两组术前、术中及术后与早产儿消化道穿孔预后不良相关的因素，采用Logistic 回归分析筛选早产儿消 化道穿孔预后不良的危险因素。结果:早产儿消化道穿孔的病死率为25.84%，坏死性小肠结肠炎（NEC）和胃壁肌层缺损是早产 儿消化道穿孔常见的病因。单因素分析显示生存组患儿从发现气腹至手术时间在8 h 之内的比例显著高于预后不良组 （χ2=15.22，P＜0.01）。预后不良组合并脓毒性休克的比例显著高于生存组（χ2=33.19，P＜0.01）。预后不良组术后合并需非计划二次 手术的并发症比例显著高于生存组（χ2=7.24，P＜0.01）。Logistic 回归分析显示脓毒性休克（OR=0.06，95%CI:0.02~0.21，P＜0.01）和 气腹至手术时间大于8 h（OR=0.23，95%CI:0.07~0.81，P＜0.05）是早产儿消化道穿孔短期预后不良的危险因素。结论:NEC 和胃 壁肌层缺损是早产儿消化道穿孔的主要病因，脓毒性休克和从气腹发生至手术时间大于8 h 是早产儿消化道穿孔短期预后 不良的危险因素。     

Ethical global health in nursing education: An integrative review

AimThe purpose of this integrative review is to provide a comprehensive review of ethical considerations for host communities and nursing programs in planning, implementing and evaluating global health experiences for nursing students.BackgroundGlobal health experiences for nursing students are proliferating rapidly across university settings while at the same time decreasing the average time spent in the host country engaged with local communities. Global health experiences are an area where students can experience ethics as it is applied across varied contexts including resource limited international settings. As nursing education expands its global programming, exploring the ethical implications of designing, implementing and evaluating GHEs becomes pivotal to build respectful, sustainable relationships with global partners and best prepare nursing students for ethical professional practice in an interconnected world.DesignWe conducted an integrative review to examine ethical considerations in development of ethical global health experiences that benefit, rather than harm, host communities and participating nursing student guests.MethodsThe search included articles published in English language, peer-reviewed journals between 1998 and 2021 that discussed ethics in the context of nursing students traveling internationally for global health experiences. Eighteen articles met criteria for review.ResultsOverall, findings demonstrate relatively little research specific to ethical engagement in global health experiences. The articles in this integrative review discussed a range of ethical attributes including reciprocity or collaboration, respect, sustainability or commitment, justice and openness. Recommendations based on research and non-research articles are provided.ConclusionsEthical comportment in global health experiences requires careful planning, implementation and evaluation to assure an equitable and sustainable partnership between host community, faculty and nursing student guests.

Redefining “low risk”: Outcomes of surgical aortic valve replacement in low-risk patients in the transcatheter aortic valve replacement era

ObjectivesGuidelines suggest aortic valve replacement (AVR) for low-risk asymptomatic patients. Indications for transcatheter AVR now include low-risk patients, making it imperative to understand state-of-the-art surgical AVR (SAVR) in this population. Therefore, we compared SAVR outcomes in low-risk patients with those expected from Society of Thoracic Surgeons (STS) models and assessed their intermediate-term survival.MethodsFrom January 2005 to January 2017, 3493 isolated SAVRs were performed in 3474 patients with STS predicted risk of mortality <4%. Observed operative mortality and composite major morbidity or mortality were compared with STS-expected outcomes according to calendar year of surgery. Logistic regression analysis was used to identify risk factors for these outcomes. Patients were followed for time-related mortality.ResultsWith 15 observed operative deaths (0.43%) compared with 55 expected (1.6%), the observed:expected ratio was 0.27 for mortality (95% confidence interval [CI], 0.14-0.42), stroke 0.65 (95% CI, 0.41-0.89), and reoperation 0.50 (95% CI, 0.42-0.60). Major morbidity or mortality steadily declined, with probabilities of 8.6%, 6.7%, and 5.2% in 2006, 2011, and 2016, respectively, while STS-expected risk remained at approximately 12%. Mitral valve regurgitation, ventricular hypertrophy, pulmonary, renal, and hepatic failure, coronary artery disease, and earlier surgery date were residual risk factors. Survival was 98%, 91%, and 82% at 1, 5, and 9 years, respectively, superior to that predicted for the US age-race-sex–matched population.ConclusionsSTS risk models overestimate contemporary SAVR risk at a high-volume center, supporting efforts to create a more agile quality assessment program. SAVR in low-risk patients provides durable survival benefit, supporting early surgery and providing a benchmark for transcatheter AVR.     

胸段食管癌累及野放疗与扩大野放疗对危及器官的辐射剂量学分析

目的 研究胸段食管癌逆向调强放射治疗（IMRT）中累及野照射与扩大野照射对危及器官（OAR）受照剂量的影响。方法 40例胸段食管癌患者分别行累及野靶区勾画和扩大野靶区勾画并勾画危及器官，制定IMRT计划，评估2个计划的靶区适形指数（CI）和均匀性指数（HI）及危及器官的剂量学参数，剂量学参数比较采用配对t检验。结果 2种计划的PTV均能满足处方剂量要求，PTV在CI、HI上相近（P = 0.317、0.130）。两组间平均肺剂量、两肺V₅、两肺V₂₀、两肺V₃₀、脊髓D_mean、心脏D_mean、心脏D_max、心脏V₃₀、心脏V₄₀、心脏V₆₀差异均存在统计学意义（P < 0.01）。结论 胸段食管癌患者行累及野照射与扩大野比较，可降低正常器官的受照剂量，从而降低放射性损伤风险。

Navigating nursing curriculum change during COVID-19 pandemic: A systematic review and meta-synthesis

AimTo consolidate the evidence around the experiences of nursing undergraduates and faculty members navigating through remote and online education during the COVID-19 pandemic.BackgroundThe Coronavirus disease 2019 caused by the SARS-CoV-2 Virus (COVID-19) has placed massive pressure on healthcare, economic and education systems globally. Restrictive social distancing policies and public health measures necessitated educational institutions to switch from face-to-face to remote and online education to sustain the learning process. These changes have created an uncertain path and undue stress for healthcare learners and faculty, especially for professional roles that traditionally require more hands-on and access to clinical practice particularly pre-licensure nursing students. As such, there is an urgent need to consolidate evidence on the experiences of nursing undergraduates and faculty members as they navigate the rapid transition from face-to-face to remote and online education to ensure continuity of learning in achieving optimal learning outcomes and to support them during current and future public health crises.DesignA systematic review and meta-synthesis of the qualitative literature was undertaken using Sandelowski and Barroso’s approach.MethodsSix electronic databases, CINAHL, Embase, ERIC, PsycINFO, PubMed and Scopus, were searched systematically using the eligibility criteria from December 2019 to September 2022. The Critical Appraisal Skills Program checklist for qualitative studies was used to conduct the critical appraisal of the selected articles.ResultsForty-seven studies were included in this review, which encapsulates the experiences of 3052 undergraduates and 241 faculty members. An overarching meta-theme ‘Remote and online education: a rollercoaster ride’, emerged along with three main meta-themes: (1) Transition to remote and online education: A turbulent road, (2) Acceptance of the untravelled road, (3) Hopes and recommendations for the road ahead.ConclusionTo improve nursing undergraduates’ and faculty member’s navigation of remote and online education, more institutions should move towards establishing hybrid education as the new ‘normal’ and exercise prudence in the organisation and delivery of curriculum, teaching, well-being and clinical attachment contingencies of their healthcare courses.
