小肠异位胰腺 1例报告及文献复习

目的探讨异位胰腺的诊治，提高对该疾病的认识以减少误诊。方法回顾性分析 1例小肠异位胰腺病人的临床表现、诊断及治疗经过，结合文献分析其组织病理分型、临床表现和治疗经验。结果病人因“突发腹痛 1d”入院。入院后在全麻下急诊行开腹探查术，于术中见“小肠表面可及一肿物，肿物穿孔可见小肠内容物溢出”。术后病理证实肿物为异位胰腺。术后恢复满意，术后第 90天随访无并发症及影像学检查异常。结论异位胰腺属于一种先天性异常，缺乏特异性诊断方法，早期多无症状，因此可保守治疗；如有症状或术中意外发现为异位胰腺组织时，可手术切除。     

BCL2 G quadruplex-binding small molecules: Current status and prospects for the development of next-generation anticancer therapeutics

B cell lymphoma 2 (BCL2) overexpression in a range of human tumors is often related to chemotherapy resistance and poor prognosis. GC-rich regions upstream of the P1 promoter in human BCL2 can form G-quadruplex (G4) structures through the stacking of four Hoogsteen-paired guanine bases. Stabilizing the G4 fold implies the inhibition of BCL2 expression and, thus, small molecules that selectively bind to the G4 are promising anticancer candidates. In this review, we discuss the structural aspects, binding affinity, selectivity, and biological activity of well-characterized BCL2 G4 binding ligands in vitro and in vivo. We also explore future directions in the research and development of G4-based anticancer therapeutics.     

Assessing Southeastern Advanced Practice Registered Nurses’ Business and Operational Skill Sets

As advanced practice registered nurses (APRNs) open private practices in medically underserved areas, clinical, practice management, and business skills are needed conjunctively to remain operational. Further information is needed to understand APRN business and entrepreneurial skill needs. A convenience sample assessed perceptions of confidence in business and operational skill sets needed for entrepreneurial roles in 102 APRNs, representing diversity of subspecialties and practice locations in 4 southeastern states with provider shortages: Alabama, Florida, Mississippi, and Tennessee. Sustaining practices in underserved areas requires providing innovative educational offerings to address APRN business skills needs.     

Living with the financial consequences of cancer: A life course perspective

Abstract

Purpose

Financial hardship can be a major cause of distress among persons with cancer, resulting in chronic stress and impacting physical and emotional health. This paper provides an analysis of the lived experience of cancer patients’ financial hardship from diagnosis to post-treatment.     

Prognostic Model and Nomogram for Estimating Survival of Small Breast Cancer: A SEER-based Analysis

BackgroundDifferent clinicopathologic characteristics could contribute to inconsistent prognoses of small breast neoplasms (T1a/T1b). This study was done to conduct a retrospective analysis and establish a clinical prediction model to predict individual survival outcomes of patients with small carcinomas of the breast.Materials and MethodsBased on the Surveillance, Epidemiology, and End Results (SEER) database, eligible patients with small breast carcinomas were analyzed. Univariate analysis and multivariate analysis were performed to clarify the indicators of overall survival. Pooling risk factors enabled nomograms to be constructed and further predicted 3-year, 5-year, and 10-year survival of patients with small breast cancer. The model was internally validated for discrimination and calibration.ResultsA total of 17,543 patients with small breast neoplasms diagnosed between 2013 and 2016 were enrolled. Histologic grade, lymph node stage, estrogen receptor or progesterone receptor status, and molecular subtypes of breast cancer were regarded as the risk factors of prognosis in a Cox proportional hazards model (P < .05). A nomogram was constructed to give predictive accuracy toward individual survival rate of patients with small breast neoplasms.ConclusionsThis prognostic model provided a robust and effective method to predict the prognosis of patients with small breast cancer.     

医学本科生在儿外科实习中的困惑和解决策略

实习是医生从理论步入实战最重要的经历。2014年国家七部委联合出台《意见》:进入临床工作的住院医师要求本科必须取得毕业证、规培证、执业证才有资格。也就是本科毕业后必须进行为期3年的规范化培训才有资格进入临床。这种教学模式对医学本科生实习心态波动很大。对是否考研,如何选择就业充满困惑,尤其是面对难度高、收入低、稀缺小专业或者不喜欢的专业,抵触、焦虑、逃避成了学生最常见反应。他们认为是浪费自己读书时间,耽误考研,以至于学生和代教教师在实际工作中普遍表现得敷衍、懈怠。如何改善现状和帮助学生走出困境,不仅需要医院深化教学改革,同时政府行为、政策也亟待完善或改革。     

Risk factors and management of stoma-related obstruction after laparoscopic colorectal surgery with diverting ileostomy

BackgroundStoma-related obstruction (SRO) is defined as small bowel obstruction occurring around the limbs of diverting ileostomy (DI). This study was aimed to investigate the incidence, risk factors, and management of SRO after laparoscopic colorectal surgery with DI creation.MethodsThis study included 155 patients who underwent laparoscopic colorectal surgery with DI creation for rectal cancer (n = 138), ulcerative colitis (UC) (n = 14), and familial adenomatous polyposis (FAP) (n = 3) between 2011 and 2019. Univariate and multivariate analyses were performed to identify the risk factors of SRO.ResultsThe incidence of SRO was 7.7% (n = 12), and it was significantly lower (P < 0.01) in patients with lower anterior resection or intersphincteric resection (4.3%) than in those with ileal-pouch anal anastomosis (IPAA) (35.2%). The multivariate analysis revealed that IPAA was independently associated with the development of SRO (P = 0.001; odds ratio, 9.4; 95% confidence interval, 2.5–35.4). Eleven of 12 patients (92%) with SRO required trans-stomal tube decompression, and 8 of those (67%) underwent early stoma closure.ConclusionIPAA was an independent risk factor of SRO in laparoscopic colorectal surgery with DI creation. Early stoma closure was needed in most cases of SRO.
