Assessment of internal mammary artery injury after blunt chest trauma: a literature review

The occurrence, bleeding, and treatment of internal mammary artery (IMA) injury after blunt chest trauma have not been well described in the literature. We reviewed articles published from July 1977 to February 2014 describing IMA injury after blunt chest trauma in 49 patients. There was a predominant incidence in males and on the left side. Blunt trauma to the IMA can cause anterior mediastinal hematoma, hemothorax, pseudoaneurysm, arteriovenous fistula, and extra-pleural hematoma. Of the 49 patients studied, 20 underwent embolization, 22 underwent surgical operation, 4 were managed by clinical observation, and 3 had undescribed treatment. Different parts and extents of IMA injury, adjacent vein injury, as well as the integrity of the pleura determined differences in bleeding modality. Prompt diagnosis, complete hemostasis, aggressive resuscitation, and multidisciplinary teams are recommended for patients with IMA injury.

本文针对某矿1500大巷由于3#联络巷西段压力过大,造成巷道破坏严重,影响井下通风和运输作业的问题,提出了采用注浆锚杆对大巷围岩进行注浆加固的修复措施,保证了1500大巷的正常使用,取得了一定的经济效益。     

深部高应力影响下软岩巷道支护技术研究

深部矿井高应力影响下软岩巷道支护的稳定性问题,是世界巷道支护中普遍存在的难题,各国业内专家都从理论和实践,技术与工艺,材料与装备上进行大量研究,提出了主动性支护的理念和原则。然而,对这一理念和原则的推广应用,却又因不同国度和自然条件而呈现不同的状况。本文结合唐山矿的实际情况,研究制定了深部高应力影响下软岩巷道支护技术方案,并取得了良好的支护效果。     

对我国西北地区沙尘暴问题的分析及预测研究

沙尘暴是一种常见的灾害性天气现象,有着爆发频繁、影响广、危害严重等特征。如今对沙尘暴的分析及趋势预测研究已成为了国内外专家学者关注的热点和焦点。本文针对我国西北地区的沙尘暴问题,利用1961～2005年中国145个区站点观测的沙尘暴天数资料,首先,对西北各主要地区沙尘暴进行了整体分析;然后,确定出了各地区和区站沙尘暴严重性的大小;最后,对各地区各区站沙尘暴情况的大致趋势进行了灰色预测分析,为政府关于沙尘暴进行防范、管理与治理提供了指导性信息。

基于AHP对抗精神疾病药物疗效的综合评价

目的 探讨基于AHP综合评价法判断利培酮、阿立哌唑和氯氮平治疗精神分裂症疗效的方法.方法 将判断药物疗效的相关因素归纳为6个因素,9个水平并建立评价指标体系,收集评价指标的原始值,确定与各项评价指标相对应的权重系数,建立线性加权综合法模型,利用AHP计算各系统的综合评价值.结果 三类药物综合评价值得到,阿立哌唑＞利培酮＞氯氮平.结论 研究建立了药物疗效评判模型,并对研究药物进行定量分析,避免单因素判断药物疗效,而使药物疗效的判断更加客观,合理,全面.基于AHP综合评价法对抗精神疾病药物疗效的定量分析,为综合评价法在药物治疗的评判中提供了有利的算法支持,为后面的研究工作提供了有效依据.     

Reduced psychiatric symptoms at 6 and 12 months’ follow-up of psychotherapeutic and psychoeducative group interventions for children exposed to intimate partner violence

BackgroundLong-term follow-up studies of interventions for children exposed to intimate partner violence are few, and the sustainability of their outcomes often remains unexplored and uncertain. Current research including follow-up assessment suggests that treatment gains may be maintained or continue post termination. In addition some children may show increased levels of symptoms.ObjectiveThe present effectiveness study investigated the long-term outcomes of two established group interventions for children exposed to intimate partner violence and their non-offending parent.Participants and SettingThe study included 50 children, 24 girls and 26 boys, aged 4 to 13 years attending a psychotherapeutic child and adolescent mental health service intervention and a psychoeducative community-based intervention.MethodsBackground information, child and parental mental health problems, trauma symptoms, and exposure to violence were assessed pre- and post treatment and at 6 and 12 months’ follow-up.ResultsSustained treatment gains and late improvements in children’s internalizing and externalizing symptoms and in symptoms of traumatic stress were recorded from post treatment to the follow-up assessments (p = .004– .044; d = 0.29–0.67). No significant increase in symptoms was reported. Additionally, very little continued or renewed child exposure to violence was reported.ConclusionsThe results of the study indicate that the children did benefit from the two interventions studied and that the outcomes of reduced child symptoms and protection from exposure to violence were sustainable. Children with severe trauma symptoms benefited the most, though maternal psychological problems may for some have hindered recovery. Clinical implications are discussed.     

Weathering the storm: COVID-19 infection in patients with hematological malignancies

The coronavirus disease 2019 (COVID-19) is an emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Within a matter of months, this highly contagious novel virus has led to a global outbreak and is still spreading rapidly across continents. In patients with COVID-19, underlying chronic diseases and comorbidities are associated with dismal treatment outcomes. Owing to their immunosuppressive status, patients with hematological malignancies (HMs) are at an increased risk of infection and have a worse prognosis than patients without HMs. Accordingly, intensive attention should be paid to this cohort. In this review, we summarize and analyze specific clinical manifestations for patients with coexisting COVID-19 and HMs. Furthermore, we briefly describe customized management strategies and interventions for this susceptible cohort. This review is intended to guide clinical practice.
