Gender and Burnout Syndrome among Health Care Workers in Ethiopia - A Systematic Review and Meta-Analysis 埃塞俄比亚卫生保健工作者的性别和倦怠综合征——系统回顾和荟萃分析
Tegegne Kt, Tegegne Et, Tessema Mk, Bagajjo Ws
The purpose of this meta-analysis was to assess the association between Gender and Burn out syndrome among health care workers in Ethiopia. Previous findings on the association of gender and burn out syndrome have reported different results. We use data from four studies to do a metaanalysis. We applied the random-effects analytic model and calculated a pooled odds ratio. The odds ratios for all studies revealed no statistically significant association of Burn out syndrome with Male relative to Female (OR = 1.15; 95% CI: 0.48-2.71, Heterogeneity: Tau² = 0.55; Chi² = 12.17, df = 3 (P = 0.007); I² = 75%, Test for overall effect: Z = 0.31 (P = 0.76). The proportion of Burn out syndrome among male and female health professionals is 31.31% (578). 35.43% (302) respectively. The overall proportion of Burn out syndrome among health professionals is 32.73% (880).
本荟萃分析的目的是评估埃塞俄比亚卫生保健工作者中性别与倦怠综合征之间的关系。先前关于性别和倦怠综合症之间关系的研究报告得出了不同的结果。我们使用四项研究的数据进行荟萃分析。我们应用随机效应分析模型,计算了合并优势比。所有研究的优势比均显示,男性相对于女性,燃尽综合征与男性之间无统计学显著关联(OR = 1.15;95% CI: 0.48-2.71,异质性:Tau²= 0.55;Chi²= 12.17,df = 3 (P = 0.007);I²= 75%,总体效果检验:Z = 0.31 (P = 0.76)。男性和女性卫生专业人员中倦怠综合征的比例为31.31%(578人)。35.43%(302)。在卫生专业人员中,倦怠综合征的总体比例为32.73%(880人)。

Purpose: To assess the agreement between 123I-metaiodobenzylguanidine or [123I]-I-mIBG and Whole Body Magnetic Resonance Imaging with diffusion-weighted whole-body imaging with background body signal suppression (WB MRI-DWIBS) in High and Intermediate risk Neuroblastoma, a retrospective review was performed on [123I]-I-mIBG and DWIBS paired scans acquired at diagnosis, response-to-therapy, after-surgery, off therapy and after relapse with systemic involvement, and osteo-bone marrow metastatic load was evaluated for each of them. Methods: 80 paired [123I]-I-mIBG and DWIBS scans were acquired for 31 patients between June 2009 and June 2019 within 30 days and without intercurrent therapy. SIOPEN Semi-quantitative Scoring Systems for NB with 12 body sections was applied at whole body MIBG and WB MRI-DWIBS acquired to evaluate the skeletal disease extent. In each case thoracic-abdominal SPECT was used to confirm or exclude doubtful scintigraphic alterations. We evaluated specificity, sensitivity, overall accuracy, positive predictive value (PPV) and negative predictive value (NPV) of WB MRI-DWIBS respect [123I]-I-mIBG scintigraphy considered as gold standard. The inverse theoretical statistic exercise was performed for [123I]-I-mIBG respect DWIBS results. Results: DWIBS and [123I]-I-mIBG images were concordant in 890 out of the 960 analyzed segments, with high agreement between the two techniques (Kendal=0.85 P < 0.0001 and Chi 536.5975 P < 0.0001). Considering [123I]-I-mIBG as gold standard, WB MRI-DWIBS overall accuracy was 93%, sensitivity 78%, specificity 95%, PPV 77% and NPV 96%. Otherwise, on the theoretical statistic exercise, [123I]-I-mIBG overall accuracy was 93%; sensitivity 77%; specificity 97%; VPP 78%; VPN 95%, respect DWIBS. [123I]-I-mIBG and WB MRI-DWIBS SIOPEN scoring resulted superimposable (Rho Spearman=0.88, P < 0.0001). Conclusion: DWIBS and [123I]-I-mIBG images showed a very high concordance: a first validation of SIOPEN Scoring System seems possible on the basis of these data. WB MRI may represent an alternative in weak-avid MIBG tumors and for follow up assessment. A multimodal imaging protocol is proposed for High and Intermediate Risk protocols.
目的:为了评估123I-metaiodobenzylguanidine或[123I]-I-mIBG与全身磁共振成像伴背景身体信号抑制(WB MRI-DWIBS)在高危和中度神经母细胞瘤中的一致性,我们对[123I]-I-mIBG和DWIBS配对扫描在诊断、治疗反应、手术后、停药后和全身累及复发时进行了回顾性回顾。并对每个患者的骨-骨髓转移负荷进行评估。方法:在2009年6月至2019年6月期间,31例患者在30天内获得80对[123I]-I-mIBG和DWIBS扫描,未进行同期治疗。采用SIOPEN半定量评分系统对12个身体切片进行全身MIBG和WB MRI-DWIBS评估骨骼疾病程度。在每个病例中,使用胸腹SPECT来确认或排除可疑的影像学改变。我们对WB MRI-DWIBS的特异性、敏感性、总体准确性、阳性预测值(PPV)和阴性预测值(NPV)进行了评价,以[123I]-I-mIBG为金标准。对[123I]-I-mIBG对DWIBS结果进行逆理论统计练习。结果:在960个分析片段中,DWIBS与[123I]-I-mIBG图像有890个一致,两种技术的一致性较高(Kendal=0.85 P < 0.0001, Chi = 536.5975 P < 0.0001)。以[123I]-I-mIBG为金标准,WB MRI-DWIBS总体准确率93%,灵敏度78%,特异性95%,PPV 77%, NPV 96%。否则,在理论统计练习中,[123I]-I-mIBG总体准确率为93%;灵敏度77%;特异性97%;VPP 78%;VPN 95%,尊重DWIBS。[123I]-I-mIBG与WB MRI-DWIBS SIOPEN评分结果重叠(Rho Spearman=0.88, P < 0.0001)。结论:DWIBS和[123I]-I-mIBG图像显示出非常高的一致性:基于这些数据,SIOPEN评分系统的首次验证似乎是可能的。WB MRI可能是弱avid MIBG肿瘤和随访评估的另一种选择。针对高、中风险协议,提出了一种多模态成像方案。

Disseminated Condensing Osteopathy 弥散性凝缩性骨病
D. André, F. Gouveia, H. Luís, J. Gaspar
A 32-year-old female patient, with no personal history or habitual medication of relief, resorted to the emergency department for pain complaints following trauma to the left hemithorax, with no associated fracture. Imagiologically, the presence of symmetrical radiopaque changes affecting the joint regions at the level of the humerus, femurs and pelvic girdle was verified. Both in the objective examination and analytically, there were no changes. The patient continued to be followed up in Internal Medicine, with the diagnosis of Osteopoikilosis. This benign entity, of autosomal dominant transmission with variable penetrance, is often diagnosed by chance. It afflicts both genders and tends to appear in childhood, persisting throughout the patient's life. As a rule, they have a symmetrical distribution and affect just-articular areas of the bone skeleton.
32岁女性患者,无个人病史或习惯性止痛药物,因左半胸外伤后疼痛主诉就诊急诊,无相关骨折。影像学证实,在肱骨、股骨和骨盆带水平存在对称的不透射线改变,影响关节区域。客观检查和分析均无明显变化。患者继续在内科随访,诊断为骨质疏松症。这种良性实体,常染色体显性遗传与可变外显率,往往是偶然诊断。它折磨男女,往往出现在儿童时期,持续整个病人的生活。通常,它们的分布是对称的,影响骨骼的关节区域。

Adipose-Derived Stem Cells: A New Player in Radiation Fibrosis Therapy 脂肪来源的干细胞:放射纤维化治疗的新参与者
A. Ejaz, Rubin Jp
Radiation therapy (RT) is an important component of modern cancer management. RT inherent more benefits as compared to both chemotherapy and surgical intervention due to its cost effectiveness, targeted effects and organ saving properties. Despite the advancement in the field of radiation delivery, radiation induced side effects; mainly to the skin is the limiting factor in delivering high intensity therapeutic doses.

Post-operative Atrial Fibrillation at the Start of Atrial Fibrillation Burden 术后房颤在房颤负担的开始
Mariana Fragão-Marques, F. Teixeira, I. Falcão-Pires, A. Leite-Moreira
Atrial Fibrillation (AF) is the most common persistent arrhythmia with adverse clinical outcomes. AF ectopic firing and re-entry depends on several mechanisms: (1) ion channel dysfunction; (2) Ca2+-handling abnormalities; (3) structural remodelling; (4) autonomic neural dysregulation. The oxidized CAMKII enzyme pathway establishes a connexion between redox imbalance and the electrical and functional cardiomyocyte properties altered in AF patients. Postoperative atrial fibrillation (PoAF) is the most common complication after cardiac surgery and a subtype of AF, associated with increased time spent in the intensive care unit (ICU), in-hospital stay, stroke incidence and 30-day and long-term mortality. Recent studies have implicated oxidative stress in AF pathophysiology including mechanisms such as an imbalance in reactive oxygen species (ROS) production, decreased endothelial nitric oxide synthase (eNOS) activity and nitric oxide unavailability. Indeed, NADPH oxidase enzymes (NOX) are largely responsible for this imbalance, which is supported by the beneficial effect of statins in early atrium electrical remodelling. Epicardial adipose tissue has a direct contact with the myocardium, located between the myocardium and visceral pericardium, and it has been established a clinical relationship between EAT and the development of AF. In this review, we explore pathophysiological mechanisms of AF and POAF, as well as its implications for management.
心房颤动(AF)是最常见的具有不良临床结果的持续性心律失常。心房纤颤异位发射和再入取决于以下几个机制:(1)离子通道功能障碍;(2) Ca2+处理异常;(3)结构改造;(4)自主神经失调。氧化CAMKII酶途径在房颤患者的氧化还原失衡与心肌细胞电和功能特性改变之间建立了联系。术后心房颤动(PoAF)是心脏手术后最常见的并发症,也是房颤的一种亚型,与在重症监护病房(ICU)的时间增加、住院时间增加、卒中发生率增加以及30天和长期死亡率增加有关。最近的研究表明,氧化应激与房颤的病理生理有关,包括活性氧(ROS)产生失衡、内皮一氧化氮合酶(eNOS)活性降低和一氧化氮不可用等机制。事实上,NADPH氧化酶(NOX)在很大程度上是造成这种失衡的原因,他汀类药物在早期心房电重构中的有益作用支持了这一点。心外膜脂肪组织与心肌直接接触,位于心肌和内脏心包之间,已经建立了EAT与房颤发生的临床关系。本文将探讨房颤和POAF的病理生理机制及其对治疗的意义。
