HIV/AIDS患者结核潜伏感染的影响因素研究

背景 结核病是导致人免疫缺陷病毒/获得性免疫缺陷综合征（HIV/AIDS）患者死亡的首要原因，而HIV感染也是导致结核潜伏感染（LTBI）发展为结核病的主要危险因素。因此，对HIV/AIDS患者进行LTBI筛查和治疗是预防该类人群结核病的发生从而减少其死亡的重要举措。 目的 对宁夏回族自治区银川市市区内HIV/AIDS患者进行LTBI筛查，并分析其影响因素，识别高危人群，为HIV/AIDS患者结核病的预防性治疗提供科学依据。 方法 选取2021年3—8月于宁夏回族自治区银川市市区内定点管理单位治疗的546例HIV/AIDS患者为研究对象。通过现场问卷调查及查阅患者管理档案的方式收集HIV/AIDS患者的一般资料，其中一般人口学特征包括性别、年龄、民族、学历、婚姻状况、家庭人均年收入、职业类型、体质指数（BMI）、吸烟情况、饮酒情况等；临床资料包括慢性病患病情况、与结核病患者密切接触情况、HIV/AIDS确诊时长、抗病毒治疗时长、合并其他感染情况、近期CD4+ T淋巴细胞计数（CD4）等。通过结核菌素皮肤试验（TST）对研究对象进行LTBI筛查，根据TST结果将546例HIV/AIDS患者分为非LTBI组（TST阴性413例）和LTBI组（TST阳性133例）。比较两组患者的一般资料，采用多因素Logistic回归分析探讨HIV/AIDS患者发生LTBI的影响因素，并利用R软件建立限制性立方样条模型拟合CD4与LTBI风险之间的量效关系。 结果 银川市市区内HIV/AIDS患者的TST阳性率为24.4%。已婚〔OR=0.544，95%CI（0.321，0.922），P<0.05〕是HIV/AIDS患者发生LTBI的保护因素；吸烟〔OR=1.919，95%CI（1.213，3.037），P<0.05〕、与结核病患者有过密切接触〔OR=11.100，95%CI（2.889，42.648），P<0.05〕是HIV/AIDS患者发生LTBI的危险因素。限制性立方样条模型拟合结果显示，HIV/AIDS患者的CD4与LTBI风险呈近似"n"形的非线性关系（非线性检验χ2=29.080，P<0.001）。 结论 应重点关注HIV/AIDS患者中未婚、吸烟、与结核病患者有过密切接触人群LTBI的发生情况，并及时进行预防性治疗；对于CD4较低的患者，建议采用多种方法进行LTBI筛查。     

The Impact of Patient Access to Their Electronic Health Record on Medication Management Safety: A Narrative Review

IntroductionAs the American’s Federal Health Insurance Portability and Accountability Act (HIPAA) stated that patients should be allowed to review their medical records, and as information technology is ever more widely used by healthcare professionals and patients, providing patients with online access to their own medical records through a patient portal is becoming increasingly popular. Previous research has been done regarding the impact on the quality and safety of patients’ care, rather than explicitly on medication safety, when providing those patients with access to their electronic health records (EHRs).AimThis narrative review aims to summarise the results from previous studies on the impact on medication management safety concepts of adult patients accessing information contained in their own EHRs.ResultA total of 24 studies were included in this review. The most two commonly studied measures of safety in medication management were: (a) medication adherence and (b) patient-reported experience. Other measures, such as: discrepancies, medication errors, appropriateness and Adverse Drug Events (ADEs) were the least studied.ConclusionThe results suggest that providing patients with access to their EHRs can improve medication management safety. Patients pointed out improvements to the safety of their medications and perceived stronger medication control. The data from these studies lay the foundation for future research.     

62例行神经外科手术治疗的获得性免疫缺陷综合征合并中枢神经系统感染者的临床特点

目的探讨经神经外科手术治疗的获得性免疫缺陷综合征（AIDS）合并中枢神经系统感染者的临床特点。 方法回顾性分析2012年1月至2018年12月于首都医科大学附属北京地坛医院神经外科行手术治疗的62例AIDS合并中枢神经系统感染者的临床资料。 结果经手术治疗的62例AIDS合并中枢神经系统感染者占神经外科同期收治的AIDS合并中枢神经系统病变患者的28.4%（62/218），主要临床表现为发热、颅内高压、功能障碍、头晕以及癫痫。32例（51.6%）患者接受分流术，11例（17.7%）患者行病变活检术，19例（30.6%）患者开颅行颅内占位切除术。经实验室检测及术后病理确诊的62例患者中真菌感染33例（53.2%），病毒及梅毒肉芽肿感染各1例（1.6%），寄生虫感染5例（8.1%），结核分枝杆菌感染8例（12.9%），细菌感染4例（6.5%），不明原因感染9例（14.5%），混合性感染1例（1.6%）。经手术治疗后，46例（74.2%）患者好转，14例（22.6%）患者无变化，2例（3.2%）患者放弃治疗。 结论AIDS合并中枢神经系统感染病原谱广泛，临床表现以发热、颅内高压、功能障碍、头晕、癫痫为主，真菌感染发病率最高，手术干预为此类疾病诊疗的重要手段之一，可提高其诊疗效率。     

Hémophilie acquise auto-immune : quelle est la place du rituximab dans la stratégie thérapeutique ? Réflexion à partir d’une série monocentrique de 8 patients et revue de la littérature

IntroductionAutoimmune acquired haemophilia is a rare autoimmune disease. The purpose of immunosuppressive therapy is to stop the production of autoantibodies that inhibit clotting factors VIII or IX. A corticosteroids-cyclophosphamide combination is recommanded as first-line therapy. From our experience at the University Hospital of Nîmes, we discuss the place of rituximab in the therapeutic arsenal.MethodsWe report a monocentric observational retrospective study. Our data are discussed in light of literature data, in particular cohorts EACH2 and SACHA.ResultsEight patients (7 with FVIII anibodies) were consecutively included from 2005. The average age was 68.5 years with a male predominance (62.5%). Bleeding manifestations were usually spontaneous and superficial. A pathology, mostly autoimmune or neoplastic, was associated in 5/8 patients. A “by-pass” haemostatic treatment was prescribed for 3/8 patients. Rituximab was prescribed for 5/8 patients, three times as first-line therapy, and always associated with corticosteroids. Three patients received a cyclophosphamid/cortisone combination, two were treated exclusively with oral corticosteroids. Remission was obtained in all patients, without subsequent relapse. The average time to obtain remission under rituximab (after the first injection) was 32.5 days (10–143). The results observed in our series of patients are consistent with the data from the literature.ConclusionsRituximab appears to be an effective and well-tolerated treatment for autoimmune acquired haemophilia. However, its place remains to be specified.     

血清胱抑素C和尿微量白蛋白联合检测在人类免疫缺陷病毒感染者肾功能损伤检测中的应用价值

目的评估血肌酐和尿常规的常规检测基础上联合血清胱抑素C和尿微量白蛋白检测在人类免疫缺陷病毒（HIV）感染者肾功能损伤检测中的应用价值。 方法以2019年2～5月于首都医科大学附属北京地坛医院感染一科住院的169例HIV感染者为研究对象，完善其尿常规、尿微量白蛋白、血肌酐、血清胱抑素C检测；分析尿蛋白及尿微量白蛋白的阳性检出率及其差异，血肌酐升高及血清胱抑素C升高的比例及其差异。计算应用替诺福韦酯（TDF）及合并丙型肝炎、高血压、糖尿病、肿瘤的肾功能损伤的相对危险度。 结果169例HIV感染者中尿常规示尿蛋白阳性者5例（3.0%），尿微量白蛋白升高者17例（10.1%），两者阳性检出率差异具有统计学意义（χ² = 5.9、P = 0.007）。血肌酐升高者10例（5.9%），血清胱抑素C升高者20例（11.8%），两者阳性检出率差异具有统计学意义（χ² = 3.0、P = 0.042）。在尿常规和血肌酐检测的基础上联合检测尿微量白蛋白和血清胱抑素C的总体阳性检出率为49例（30.0%）。CD4⁺ T淋巴细胞计数< 200个/μl与≥ 200个/μl组患者血清胱抑素C水平分别为0.94（0.83，1.05）mg/L、0.85（0.77，0.95）mg/L，差异具有统计学意义（Z =-3.02、P = 0.003）。应用TDF及合并丙型肝炎、高血压、糖尿病、肿瘤的肾功能损伤的相对危险度分别为1.1、1.5、1.9、2.2和1.4。 结论HIV感染者中，单纯以尿常规为依据评估有无蛋白尿，以血肌酐水平为依据评估肾小球滤过功能会低估肾功能损伤的患病率。在常规检测血肌酐和尿常规的基础上联合检测血清胱抑素C和尿微量白蛋白在提高HIV感染者肾功能损伤检出率方面具有重要的应用价值。低CD4⁺ T淋巴细胞计数、应用TDF及合并丙型肝炎、高血压、糖尿病、肿瘤均为肾功能损伤的危险因素。     

The Neurology of Acquired Pedophilia

ABSTRACT

The clinicoanatomic cases of acquired pedophilia that have been published in the medical and forensic literature up to 2019 are reviewed. Twenty-two cases fit our inclusion criteria. All but one were men, and in only one case the injury was localized to the left hemisphere. Hypersexuality was present in 18 cases. The damaged areas fell within the frontotemporoinsular cortices and related subcortical nuclei; however, the anterior hypothalamus was spared. Damage to parts of the right frontotemporoinsular lobes with sparing of the anterior hypothalamus seems to be critical for the emergence of acquired pedophilia.     

《艾滋病诊疗指南第三版(2015版)》更新解读

2015年中华医学会感染病学分会艾滋病学组发布了第三版《艾滋病诊疗指南》。新版指南强调抗病毒治疗时点前移:一旦成人确诊感染人类免疫缺陷病毒(HIV), 若无禁忌宜尽早启动抗HIV治疗。对于合并机会性感染的HIV感染者, 在感染控制、病情稳定后也应及早开始抗病毒治疗。尤其强调HIV合并结核患者在CD4阳性淋巴细胞数少于200/μL的情况下, 建议抗结核两周内即开始抗病毒治疗。在抗HIV治疗用药中, 淘汰了一些毒副作用大、依从性较差的药物, 如司他夫定、去羟肌苷、茚地那韦等, 优选抗病毒效力强、服药方便的组合, 如拉米夫定、替诺福韦、依非韦伦组合。对于HIV感染的婴幼儿, 亦主张及早抗HIV治疗。对于五岁以内的幼儿, 主张确诊后即启动抗病毒治疗。对于HIV感染的孕产妇, 建议尽快予以全程、联合抗HIV治疗, 寓防于治。     

Onset,time course and prediction of spasticity after stroke or traumatic brain injury

ObjectiveTo describe spasticity from the onset of acquired brain injury, time course over the first year and factors associated with prediction of the development of spasticity.MethodsRecent relevant literature known to the authors, along with a complementary search yielding a total of 9 articles, represented the base for this scoping review.ResultsSpasticity can be seen in the first week after brain injury and is more common in the upper than lower extremity. The severity of upper-limb impairment is a major factor in the development of spasticity during the first year after stroke. The prevalence of severe spasticity seems to increase during the first year. The combination of reduced arm motor function and spasticity in an early phase (4 weeks post-stroke) is an important predictor of the development of severe spasticity after 12 months. Spontaneous reduction in spasticity was seldom reported but may occur, especially in mild forms of spasticity.ConclusionSigns of spasticity can often be noted within the first 4 weeks after brain injury and is more common in the upper than lower extremity. Impaired sensorimotor function is a predictor. These findings highlight the importance to follow up patients with increased risk of developing severe spasticity to be able to start adequate spasticity treatment and prevent the negative consequences of spasticity. Understanding spasticity onset and progression also provides a basis for the development of effective therapies.
