复发性流产患者易栓症指标筛检的意义

目的探讨易栓症相关指标与不明原因复发性流产(URSA)的相关性,为URSA患者的病因排查和治疗提供参考。方法选取2016年11月—2018年3月上海交通大学医学院附属国际和平妇幼保健院104例流产次数≥2次的URSA患者作为URSA组,以45例健康经产妇作为对照组,检测所有研究对象血浆狼疮抗凝物(LA)阳性率、抗心磷脂抗体(ACA)阳性率、蛋白C(PC)活性、蛋白S(PS)活性、抗凝血酶(AT)活性、凝血因子Ⅻ(FⅫ)活性和D-二聚体(DD)水平。结果URSA组LA阳性率、PC活性、PS活性、AT活性、FⅫ活性、DD水平与对照组比较差异均有显著统计学意义(P<0.05)。结论LA阳性、PS缺陷、FⅫ缺陷和DD增高与URSA密切相关。LA、PS、FⅫ、DD是URSA患者体内高凝状态较好的筛查指标,联合检测AT、PC,对预测URSA血栓形成有临床指导意义。     

Louisiana's “Medically Futile” Unborn Child List: Ethical Lessons at the Post-Dobbs Intersection of Reproductive and Disability Justice

Ableist attitudes and structures are increasingly recognized across all sectors of health care delivery. After Dobbs, novel questions arose in the United States concerning how to protect reproductive autonomy while avoiding discrimination against and devaluation of disabled persons. In this essay, we examine the Louisiana Department of Health's emergency declaration, “List of Conditions That Shall Deem an Unborn Child ‘Medically Futile,’” issued August 1, 2022. We raise a number of medical, ethical, and public health concerns that lead us to argue that the declaration should be rescinded. Analysis of this ethically objectionable declaration provides valuable lessons about how to uphold both reproductive and disability justice in a post-Dobbs landscape.     

Empowering the Nurse Practitioner With the Reproductive Justice Framework

On June 24, 2022, the Supreme Court of the United States ruled to strike down Roe v. Wade (1973), a landmark decision that legalized access to abortion under the right to privacy. By overturning Roe, the decision now leaves the regulation of abortion up to each individual state. Consideration of the consequences that will affect vulnerable populations is paramount now that Roe v. Wade is overturned. Nurse practitioners who are impartial toward abortion should be introduced to Reproductive Justice, which can help them better understand the lived experiences of people with the capacity for pregnancy and the complexities surrounding abortion.     

保留自主呼吸对于重度急性呼吸窘迫综合征患者的影响：弊大于利

急性呼吸窘迫综合征（ARDS）是临床上常见的以顽固性低氧为表现的呼吸功能不全或衰竭的综合征，肺不均一性是其主要病理生理特点。传统观点认为，保留ARDS患者自主呼吸有助于改善全身氧合。但是近年来发现，对于重度ARDS患者，保留患者自主呼吸会加重肺损伤，过强的自主呼吸会导致重度ARDS患者跨肺压升高、肺内气体摆动、肺水肿加重以及人机不同步，引起患者肺内炎症加重，氧合功能恶化，最终影响患者预后，增加病死率。本文就自主呼吸对重度ARDS患者呼吸功能的影响机制展开综述。     

复发性流产患者病因构成分析

背景　复发性流产（RSA）发病率呈逐年上升趋势，严重影响妇女身心健康，目前现代医学对RSA的病因和发病机制尚未完全明确。目的　了解RSA病因的分布情况，以及流产孕周与流产次数和RSA病因之间的关系。方法　选取2018年在新疆医科大学第二附属医院确诊为RSA的患者198例，收集患者的一般资料包括年龄、自然流产次数、流产孕周，并筛查患者的病因：染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常等，并对这些资料进行回顾性分析。根据患者的流产孕周，分为早期RSA组（<12周）（155例）和晚期RSA组（≥12周）（43例）；根据流产次数分为2次组（123例）和≥3次组（75例）。分析RSA患者各病因所占比例，以及RSA病因在不同流产孕周组和不同流产次数组间的差异。结果　198例RSA患者，染色体异常9例（4.55%），生殖道解剖结构异常11例（5.56%），内分泌系统异常36例（18.18%），生殖道感染14例（7.07%），自身免疫异常30例（15.15%），不明病因98例（49.49%）。晚期RSA组患者生殖道解剖结构异常发生率大于早期RSA组，不明病因发生率低于早期RSA组（P<0.05）；早期RSA组与晚期RSA组患者染色体异常、内分泌系统异常、生殖道感染、自身免疫异常发生率比较，差异均无统计学意义（P>0.05）。流产次数2次组和流产次数≥3次组患者染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常、不明病因发生率比较，差异均无统计学意义（P>0.05）。结论　导致RSA的病因有多种，包括染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常及不明病因等多种因素，其中不明病因的RSA占多数；生殖道解剖结构异常对妊娠晚期的影响大于妊娠早期。     

Colitis following the use of immune checkpoint inhibitors: A real-world analysis of spontaneous reports submitted to the FDA adverse event reporting system

BackgroundAlthough colitis has been reported in patients treated with immune checkpoint inhibitors (ICIs), associations between colitis and ICIs had not been thoroughly assessed in real-world studies. Here, we identified and characterized significant colitis-associated with ICIs.MethodsBased on the Food and Drug Administration Adverse Event Reporting System (FAERS) from January 2004 to December 2019, the disproportionality analysis and Bayesian analysis, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN) and the multi-item gamma Poisson shrinker (MGPS) algorithms were adopted to data mining of the suspected adverse events of colitis after ICIs administrating. Clinical characteristics of patients with ICIs-associated colitis and the time to onset of colitis following different ICI regimens were collected.ResultsA total of 3786 reports of colitis adverse events were identified with ICIs. Seven ICI monotherapies were associated with the reporting of colitis. Statistically significant ROR, PRR, information component (IC), and empirical Bayesian geometric mean (EBGM) emerged for all ICI monotherapies and combination therapies. ICIs-associated colitis affected mostly male (53.51%), with a wide mean age range (60.65 to 72 years). Colitis adverse events were commonly reported in patients with melanoma and lung cancer. Adverse outcomes of colitis concerning ICI were mainly outcomes of hospitalization-initiated or prolonged and other serious. Among colitis cases, 17.43% cases of colitis concerning ICI lead to death. The adverse event of colitis occurred earliest in ipilimumab monotherapy with a median time to onset of 64.21 days (IQR: 27–69 days) among all monotherapies.ConclusionsICI may lead to severe and disabling ICIs-associated colitis during therapy. Analysis of FAERS data identified signals for adverse events of colitis with ICI regimens. Practitioners should consider the factors that may increase the likelihood of colitis. The findings support a continued surveillance and risk factor identification studies.     

Rethinking “Elective” Procedures for Women's Reproduction during Covid-19

Common hospital and surgical center responses to the Covid-19 pandemic included curtailing “elective” procedures, which are typically determined based on implications for physical health and survival. However, in the focus solely on physical health and survival, procedures whose main benefits advance components of well-being beyond health, including self-determination, personal security, economic stability, equal respect, and creation of meaningful social relationships, have been disproportionately deprioritized. We describe how female reproduction-related procedures, including abortion, surgical sterilization, reversible contraception devices and in vitro fertilization, have been broadly categorized as “elective,” a designation that fails to capture the value of these procedures or their impact on women's overall well-being. We argue that corresponding restrictions and delays of these procedures are problematically reflective of underlying structural views that marginalize women's rights and interests and therefore threaten to propagate gender injustice during the pandemic and beyond. Finally, we propose a framework for triaging reproduction-related procedures during Covid-19 that is more individualized, accounts for their significance for comprehensive well-being, and can be used to inform resumption of operations as well as subsequent restriction phases.     

Simultaneous detection of Aspergillus nidulans,Aspergillus luchuensis and Lichtheimia sp. in a bovine abortion

Abortion in dairy cattle may be caused by infectious (viruses, fungi and protozoa) and non-infectious causes mostly related to bad management practices and genetic factors. Recently, the significant contribution of mycotic infection to bovine abortion has been recognized. This report describes an abortion case in a Chianina cow due to Aspergillus nidulans, Aspergillus luchuensis and Lichtheimia sp. diagnosed by histology, cytology, culture and molecular assays. A mixed infection due to more than one fungus in abortion is rarely demonstrated. To our knowledge, this is the first case of bovine abortion caused by co-infection with three different moulds.
