Background: Multicentric prospective cohort investigation survey conducted between 1st of March and 1st of April 2021on SARS-CoV-2 occupational risk for German Emergency Medical Services (EMS) personnel. Study Objectives: Primary: The objective is to take stock of the use and availability of Personal Protective Equipment (PPE) in German EMS, both at managerial and employee level, during the SARS-CoV-2 pandemic. Secondary: Generate additional data on individual perceptions of risk of infection and occurrence of infections at respective places of service. Methods: Multicentric prospective cohort investigation survey conducted online at two levels of German EMS personnel—EMS managers and EMS employees, both medical and paramedical—with questions adapted slightly to fit the respective study population. Results: A total of 34 responses were received in the managerial group;a total of 2389 responses were received in the group of employees. Self-reported PPE adherence of EMS employees for confirmed SARS-CoV-2 positive patients: use of gloves (99.8%), FFP2 or FFP3 masks (99.8%), gowns or coveralls (99.1%), goggles (89.7%), face shields (24.0%), surgical masks (0.0%). Self-reported PPE adherence of EMS employees for suspected SARS-CoV-2 positive patients: gloves (98.8%), FFP2 or FFP3 masks (total: 99.4%), gowns or coveralls (total: 95.9%), goggles (85.6%), face shields (19.2%), surgical masks (0.2%). Conclusions: Findings included an overall improved self-reported adherence to PPE compared to studies that were conducted before the pandemic. Self-reported general adherence to PPE recommendations when attending to confirmed SARS-CoV-2 positive patients was good, with the exception of goggles. Self-reported adherence to PPE recommendations dropped when attending to suspected SARS-CoV-2 positive patients.

对波兰西南部Stara Kamienica山脉片岩带中层状锡矿床的成因,根据新的可靠的资料进行了重新分析。作者的看法:矿床的层状特征不应包括成因含意。与华力西期Kakonosze地块的酸性侵入体有关的热液交代作用沿着构造线贯入矿化流体。

目的探讨DSA血流定量分析软件评价血流导向装置治疗颅内大型动脉瘤后的血流特性改变,以分析血流导向装置治疗颅内大型动脉瘤的有效性.方法回顾性分析2012年8月-2013年4月采用血流导向装置（Tubridge,Microport,上海）治疗的颅内大型动脉瘤患者15例.以相同标准采集所纳入患者治疗前后常规造影图像,并通过DSA血流定量分析软件进行图像后处理,通过生成的时间密度曲线,分析载瘤动脉远端显影延迟时间、动脉瘤瘤体内血流达峰时间、瘤体内血流曲线下面积以及瘤体内血流最大斜率的变化情况.结果本组患者的支架置入技术成功率为100%,通过DSA分析软件术后即刻分析发现,与术前相比,载瘤动脉远端延迟时间缩短中位数（M）1.031 s（范围0.324~2.143 s）,动脉瘤瘤腔内血流曲线下面积（相对值）以及最大斜率（相对值）分别减少57±15和49±25.结论 Tubridge支架置入前后载瘤动脉远端显影时间延迟、瘤腔内血流曲线下面积及瘤腔内血流最大斜率的下降,证实采用血流定量分析方法评估血流导向装置对于颅内大型动脉瘤的即刻治疗效果是有效的,但其对于远期疗效的评估还有待进一步观察.

Objectives: The present study evaluated the effects of a combined nutritional supplement, containing omega-3 fatty acids (ω-3 FA) and different antioxidative micronutrients on nutrient status and disease activity in patients with rheumatoid arthritis (RA). Methods: The study was conducted as a double-blind, randomised placebo-controlled trial. A hundred patients with defined RA were allocated to the verum or placebo group. During a period of twelve weeks they were given three capsules of their specific study supplementation every day. The daily dosage of ω-3 FA was 1.35 g (thereof 900 mg eicosapentaenoic acid, EPA), 90 mg vitamin E, 600 μg vitamin A, 3 mg copper, and 75 μg selenium, or soy oil (placebo), respectively. Outcome variables were the changes in DAS 28, the number of tender and swollen joints, morning stiffness, and supply with different nutrients (e.g. serum concentration of EPA, AA and vitamin E), as well as blood lipid levels. Results: Sixty-four participants were included in this analysis: 30 receiving verum and 34 placebo. After twelve weeks of intervention, little but not significant improvements were observed in the DAS 28 and other clinical factors. Subgroup analysis revealed that the effect was much more pronounced in patients who were at least at a moderate activity of illness. Regarding the nutritional status, the serum concentration of EPA (P < 0.001), vitamin E (P < 0.01), SOD (P < 0.05), and GPx (P < 0.001) increased significantly, while AA (P < 0.001) decreased after supplementation. The concentration of triglycerides decreased significantly in the verum group (P < 0.05) but not in the placebo group. Conclusions: A twelve week add-on supplementation of a combined food supplement (ω-3 FA + antioxidants) effected modest but not significant changes in the clinical parameters in RA. Though vitamin E, SOD and GPx improved significantly, equivalent to an increased antioxidant defence. This supplementation was dedicated to enhance the nutritional s
