    我们审查了几个系统评价中的第一个发表的一个,这是世卫组织新倡议的一部分,旨在评估人造射频电磁辐射(RF-EMF)与人类不良健康影响之间的关联。审查的审查涉及非人类哺乳动物的怀孕和出生结果的实验研究。该评论声称,分析的数据没有提供足够的结论来为监管层面的决策提供信息。我们的目的是评估此系统评价的质量,并评估其结论与孕妇及其后代的相关性。质量和相关性在审查本身的前提下进行了检查:例如,我们没有质疑论文的选择,也不是选择的统计方法。虽然世卫组织的系统审查表明自己是彻底的,科学,与人类健康相关,我们发现了许多问题,这些问题使得世卫组织的审查无关紧要且存在严重缺陷.发现的所有缺陷都扭曲了结果,以支持审查的结论,即没有确凿的非热效应证据。我们证明了底层数据,当相关研究被正确引用时,支持相反的结论:有明显的迹象表明RF-EMF暴露会产生有害的非热效应。许多已发现的缺陷揭示了系统偏斜的模式,旨在隐藏在复杂的科学严谨性背后的不确定性。这篇综述的方法偏差和质量低下令人高度关注,因为它有可能破坏世卫组织在人为RF-EMF危害人类健康方面的可信度和专业性。
    We examined one of the first published of the several systematic reviews being part of WHO\'s renewed initiative to assess the evidence of associations between man-made radiofrequency electromagnetic radiation (RF-EMF) and adverse health effects in humans. The examined review addresses experimental studies of pregnancy and birth outcomes in non-human mammals. The review claims that the analyzed data did not provide conclusions certain enough to inform decisions at a regulatory level. Our objective was to assess the quality of this systematic review and evaluate the relevance of its conclusions to pregnant women and their offspring. The quality and relevance were checked on the review\'s own premises: e.g., we did not question the selection of papers, nor the chosen statistical methods. While the WHO systematic review presents itself as thorough, scientific, and relevant to human health, we identified numerous issues rendering the WHO review irrelevant and severely flawed. All flaws found skew the results in support of the review\'s conclusion that there is no conclusive evidence for nonthermal effects. We show that the underlying data, when relevant studies are cited correctly, support the opposite conclusion: There are clear indications of detrimental nonthermal effects from RF-EMF exposure. The many identified flaws uncover a pattern of systematic skewedness aiming for uncertainty hidden behind complex scientific rigor. The skewed methodology and low quality of this review is highly concerning, as it threatens to undermine the trustworthiness and professionalism of the WHO in the area of human health hazards from man-made RF-EMF.

    将物质分解为其成分,将我们引向我们所知道的最小粒子。这些颗粒形成由这些颗粒产生和携带的电磁场决定的材料结构。两种主要成分中的任何一种的变化都会导致该材料系统的变化,无论是活的有机体还是无生命的物体。后一种说法承载了生命的奥秘,生命是由一系列连续且程序化的系统变化产生的,这些变化是由具有未知功能机制的能源推动的。目前的工作是对上述的理解和潜在发现的理论方法,未知的细胞能量机制。了解细胞内生物化学的能量基础在人类和动物治疗中同样重要。此外,因为所有这些发现都为全球工业的各个领域提供了新颖的解决方案,这项理论工作的最终结果也带来了电子行业新发现的想法。
    Dissection of the matter into its constituents leads us to the smallest particles that we know. These particles form a material structure that is determined by the electromagnetic field generated and carried by those particles. Changes in any of the two major constituents leads to changes in that material system, be it a living organism or a lifeless object. The latter statement carries the mystery of life that is born from a continuous and programmed series of system changes fuelled by an energy source with a yet unknown functioning mechanism. The present work is a theoretical approach towards the understanding and potential discovery of the aforementioned, not-yet-known cellular energetic mechanism. Understanding the energetic basis of intracellular biochemistry is equally important in human and animal therapeutics. Additionally, as all such discoveries offer novel solutions in various fields of the global industry, the final outcome of this theoretical work also brings about the idea of a new discovery in electronics industry.

    From a cohort of 2018 evaluable consecutive cases issued from the European Clinical Trial Database, we describe the complete clinical symptomatic presentation of electrohypersensitivity (EHS) and multiple chemical sensitivity (MCS) and their association in the framework of a unique, sensitivity-related environmental neurologic syndrome. Eligibility criteria are those of the Atlanta consensus meeting for MCS, and those of WHO for EHS. There were 1428 EHS, 85 MCS and 505 EHS/MCS evaluable cases, so EHS was associated with MCS in 25%. Women appeared to be much more susceptible to EHS and/or to MCS than men, with no statistical significance between the EHS and MCS groups (p = 0.07), but the combined group revealed a more significant female sex ratio of 80.4% (p < 0.0001). All symptoms except emotional behavior were significantly more frequent in EHS patients than in healthy controls (p < 0.0001). We found no pathognomonic symptoms to establish the diagnosis of both disorders or to distinguish EHS from MCS. The three groups of patients were found to share identical symptoms, while several symptoms were found to be more significantly frequent in EHS/MCS than in EHS (p < 0.0001). From these data, we suggest that EHS and MCS are new brain disorders, generated via a common etiopathogenic mechanism.

  • 文章类型: Randomized Controlled Trial
    背景:膝骨关节炎(OA)是老年人群常见的致残疾病。膝关节OA的最佳保守治疗方法尚未完全确定。
    目的:本研究旨在评估脉冲电磁场(PEMF)联合渐进性抗阻运动(PRE)改善膝关节OA患者身体功能和疼痛的有效性。
    方法:34例膝关节OA患者(每组17例)参加了一项单盲随机对照研究。患者被随机分配接受24个疗程的PEMF和PRE(治疗组)或仅PRE(对照组)。患者在治疗前进行评估,治疗后(2个月),在3个月和6个月的随访中,使用膝关节损伤和骨关节炎结果评分(KOOS),数字疼痛评分量表(NPRS);步行速度和5次椅子站立测试。混合方差分析用于具有Bonferroni调整的统计分析。
    结果:对于任何结果,均无显著的组间交互作用(P>0.05)。然而,两组在治疗后的NPRS和KOOS得分均明显更高,3-,与基线相比,进行了6个月的随访。Further,两组在所有治疗后时间点完成5次坐椅试验和步行速度试验,时间均明显少于治疗前.没有研究结果(NPRS,KOOS,步行速度,和5次椅子站立)在任何时间点两组之间显着不同。
    结论:两种治疗方案,仅PRE与使用PEMF的PRE相比,在减轻膝关节OA患者的疼痛和改善身体功能方面同样有效。这将表明,需要确定当添加到PRE训练时可能对膝盖OA显示有益效果的PEMF的最佳参数。
    BACKGROUND: Knee osteoarthritis (OA) is a common and disabling disease among the elderly population. The optimal conservative treatment for knee OA is not well established.
    OBJECTIVE: This study aimed to assess the effectiveness of pulsed electromagnetic field (PEMF) combined with progressive resistance exercise (PRE) in improving physical function and pain in patients with knee OA.
    METHODS: Thirty-four patients with knee OA (17 in each group) participated in a single-blind randomized control study. Patients were randomly assigned to receive 24 sessions of either combined PEMF and PRE (treatment group) or PRE only (control group). Patients were evaluated at pre-treatment, post-treatment (2 months), and at 3-month and 6-month follow-ups using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Numeric Pain Rating Scale (NPRS); walking speed and 5-times chair stand test. Mixed ANOVA was used for statistical analysis with Bonferroni adjustments.
    RESULTS: There was no significant group-by-time interaction for any outcome (P> 0.05). However, both groups scored significantly higher on the NPRS and KOOS at post-treatment, 3-, and 6-month follow-up compared to their baseline. Further, both groups completed the 5-times chair stand test and walking speed test with significantly less time at all post-treatment time points than the pre-treatment. None of the study outcomes (NPRS, KOOS, walking speed, and 5 times chair stand) were significantly different between groups at any of the time points.
    CONCLUSIONS: Both treatment options, PRE only versus PRE with PEMF, were equally effective in decreasing pain and improving physical function in patients with knee OA. This would suggest that the optimal parameters for PEMF that may show beneficial effects for knee OA when added to PRE training need to be determined.

    背景:为了潜在地改善多器官功能障碍综合征(MODS)患者的受损血管舒缩,我们测试了低通量密度的电磁场是否与生物节律定义的脉冲配置(物理血管治疗BEMER®,PVT),除了标准护理,是安全可行的,可能会改善受干扰的微循环血流,从而改善全球血流动力学。
    方法:在前瞻性中,单心,单臂试点研究,纳入10例MODS患者(APACHEII评分20-35)。患者接受治疗,除了标准护理,用PVT治疗4天(3个治疗期,每天8分钟;第1天:场强10.5μT;第2天:14μT,第3天:17.5μT;第4天:21.0μT)。主要终点是PVT对舌下微循环灌注的影响,通过微血管血流指数(MFI)记录。患者安全,不良事件,并记录了结果。
    结果:与4天PVT相比,MFI增加约25%,增加在第一次PVT后立即开始,并持续4天的总治疗期。关于全球血流动力学(次要终点),在24小时内将升压药的使用减半,血流动力学稳定与4天PVT平行,心脏指数增加,每搏输出量指数,和心脏功率指数30%-50%。没有不良事件(AE)或严重不良事件(SAE)被归类为与医疗产品(PVT)或研究相关的因果关系。三名患者在28天内死亡,一名患者在28至180天内死亡。
    结论:PVT治疗是可行和安全的,可以在不妨碍标准患者护理的情况下进行。微循环血流量增加,血管升压药的使用迅速减少,与PVT治疗平行的全球血流动力学改善。这项初步研究的结果允许形成一个随机试验的概念,以进一步证明。
    BACKGROUND: To potentially improve impaired vasomotion of patients with multiple organ dysfunction syndrome (MODS), we tested whether an electromagnetic field of low flux density coupled with a biorhythmically defined impulse configuration (Physical Vascular Therapy BEMER®, PVT), in addition to standard care, is safe and feasible and might improve disturbed microcirculatory blood flow and thereby improve global haemodynamics.
    METHODS: In a prospective, monocentric, one-arm pilot study, 10 MODS patients (APACHE II score 20-35) were included. Patients were treated, in addition to standard care, for 4 days with PVT (3 treatment periods of 8 min each day; day 1: field intensity 10.5 μT; day 2:14 μT, day 3:17.5 μT; day 4:21.0 μT). Primary endpoint was the effect of PVT on sublingual microcirculatory perfusion, documented by microvascular flow index (MFI). Patient safety, adverse events, and outcomes were documented.
    RESULTS: An increase in MFI by approximately 25% paralleled 4-day PVT, with the increase starting immediately after the first PVT and lasting over the total 4-day treatment period. Concerning global haemodynamics (secondary endpoints), halving vasopressor use within 24 h, and haemodynamic stabilisation paralleled 4-day PVT with an increase in cardiac index, stroke volume index, and cardiac power index by 30%-50%. No adverse events (AEs) or serious adverse events (SAEs) were classified as causally related to the medical product (PVT) or study. Three patients died within 28 days and one patient between 28 and 180 days.
    CONCLUSIONS: PVT treatment was feasible and safe and could be performed without obstruction of standard patient care. An increase in microcirculatory blood flow, a rapid reduction in vasopressor use, and an improvement in global haemodynamics paralleled PVT treatment. Findings of this pilot study allowed forming a concept for a randomized trial for further proof.

    背景技术创伤性脑损伤(TBI)是导致残疾和死亡的全球性原因。治疗取决于减轻导致轴索损伤的继发性损伤,坏死,脑功能障碍,以及神经回路中电和化学信号的破坏。为了更好地理解TBI,研究生理学需要转化模型,诊断,和同源物种的治疗,比如猪。可以测量来自改变的神经回路的电磁场(EMF),并且历史上一直依赖于脑磁图中昂贵的屏蔽和过冷。使用专有的感应传感器,已经发现一种非侵入性的,采用工程Mu金属和铜网屏蔽头盔的非接触方法可有效测量EMFs。这尚未在猪模型中进行研究。我们希望评估该技术的功效,以评估猪的TBI依赖性EMF变化,以描述这些传感器的功效以及使用重力依赖性受控皮层撞击(CCI)的该模型。方法采用非接触式方法对尤卡坦小型酒进行评价,非侵入式专有感应传感器,具有工程双层Mu-metal和交错铜网头盔,EMF通道内的传感器连接到头盔。在诱导的重力依赖性CCI之前获得猪EMF记录,然后进行TBI后测量。评估行为变化和EMF测量值的变化。使用人工智能(AI)模型评估EMF测量。结果确定了室内“噪声”EMF测量与TBI前猪电磁场测量之间的差异。注意到损伤前和损伤后测量之间的形态学特征。AI建模区分了猪EMF中的损伤前和损伤后模式。受伤后经常发现的频率是2.5Hz和6.5Hz的峰值和11Hz的谷值。AI模型识别出斜率的变化较小,因此TBI后的EMF测量值在4.5Hz和7Hz之间的变化减小。结论第一次,已经确定,可以使用新型感应传感器和隔离到头盔和EMF通道的屏蔽来适当地测量猪的皮质功能。猪模型可以与具有明显不同的损伤前和损伤后EMF的外部噪声信号适当区分。由于可以使用这些传感器连续测量的神经回路改变,因此可以在损伤后EMF中识别出模式。非侵入性,和实时。
    Background Traumatic brain injury (TBI) is a global cause of disability and mortality. Treatment depends on mitigation of secondary injury resulting in axonal injury, necrosis, brain dysfunction, and disruption of electrical and chemical signaling in neural circuits. To better understand TBI, translational models are required to study physiology, diagnostics, and treatments in homologous species, such as swine. Electromagnetic fields (EMFs) from altered neural circuits can be measured and historically have been reliant on expensive shielding and supercooling in magnetoencephalography. Using proprietary induction sensors, it has been found that a non-invasive, non-contact approach with an engineered Mu-metal and copper mesh-shielded helmet effectively measures EMFs. This has not yet been investigated in swine models. We wished to evaluate the efficacy of this technology to assess TBI-dependent EMF changes in swine to describe the efficacy of these sensors and this model using a gravity-dependent controlled cortical impact (CCI). Methods A Yucatan miniswine was evaluated using non-contact, non-invasive proprietary induction sensors with an engineered dual-layer Mu-metal and interlaced copper mesh helmet with sensors within EMF channels connected to a helmet. Swine EMF recordings were obtained prior to induced gravity-dependent CCI followed by post-TBI measurements. Behavioral changes and changes in EMF measurements were assessed. EMF measurements were evaluated with an artificial intelligence (AI) model. Results Differences between room \"noise\" EMF measurements and pre-TBI swine electromagnetic field measurements were identified. Morphological characteristics between pre-injury and post-injury measurements were noted. AI modeling differentiated pre-injury and post-injury patterns in the swine EMF. Frequently identified frequencies seen post-injury were peaks at 2.5 Hz and 6.5 Hz and a valley at 11 Hz. The AI model identified less changes in the slope and thus decreased variation of EMF measurements post-TBI between 4.5 Hz and 7 Hz. Conclusions For the first time, it was identified that cortical function in a swine can be appropriately measured using novel induction sensors and shielding isolated to a helmet and EMF channels. The swine model can be appropriately differentiated from the external noise signal with identifiably different pre-injury and post-injury EMFs. Patterns can be recognized within the post-injury EMF due to altered neural circuits that can be measured using these sensors continuously, non-invasively, and in real time.

    电磁场(EMF)暴露水平的逐渐增加对人类健康和电子系统的正常运行构成了潜在威胁。为了了解环境EMF条件,在北京市区约400公里的道路上进行了测量,中国。测量结果表明,89%左右的采样点的电场强度在3V/m以内,其他采样点的电场强度相对较高。结合进一步的频谱分析,发现一条路段的电场强度超过了国家标准的限值。此外,为了帮助快速识别环境EMF的一般状况,本文提出了一套挖掘电场强度与人口密度和建筑物密度之间关联规则的方法。最终的关联规则表明,在人口密度中等或较低的地区和建筑物密度较低的地区,电场强度通常低于1.5V/m;在人口密度极高的地区和建筑物密度较高的地区,电场强度通常为1.5-4V/m;而电场强度高于4V/m主要发生在人口密度极高的地区。建议在人口密度极高的地区,重点加强对EMF的监测,同时不断关注城市EMF水平的趋势,从而实现对相关风险的预警和处理。
    The gradual increase in electromagnetic field (EMF) exposure levels poses a potential threat to human health and the normal operation of electronic systems. In order to know the environmental EMF conditions, measurements were carried out on roads of about 400 km in the urban area of Beijing, China. The measurement results show that the electric field strength of about 89% of the sampling points is within 3 V/m, and the electric field strength of other sampling points is relatively high. Combined with further spectrum analysis, it was found that the electric field strength of one road section exceeded the national standard limits. In addition, to help quickly identify the general condition of the environmental EMF, a set of procedures for mining the association rules between the electric field strength and population density and building density is proposed in this paper. The final association rules show that the electric field strength is usually lower than 1.5 V/m in areas with medium or lower population density and areas with low building density; the electric field strength in areas with extremely high population density and areas with high building density is usually 1.5-4 V/m; while the electric field strength higher than 4 V/m mainly occurs in areas with extremely high population density. It is recommended to focus on strengthening the monitoring of EMF in areas with extremely high population density, and at the same time continuously pay attention to the trend of the urban EMF levels, so as to achieve early warning and treatment of relevant risks.

    Ti6Al4V合金具有狭窄的加工窗口,这使得温度控制变得复杂,尤其是在大规模生产过程中。因此,对Ti6Al4V钛合金管的超声感应加热过程进行了数值模拟和实验研究,以获得稳定的加热。计算了超声频率感应加热过程中的电磁场和热场。数值分析了电流频率和电流值对温度场和电流场的影响。电流频率的增加增强了皮肤和边缘效应,但是热渗透性是在超音频范围内实现的,管的内部和外部之间的温差小于1%。施加的电流值和电流频率的增加导致管温度的增加,但是电流的影响更为突出。因此,逐步喂养的影响,往复运动,并对管坯加热温度场进行了逐步送料叠加运动评价。在变形阶段期间,与辊一起往复运动的线圈可以将管的温度保持在目标温度范围内。仿真结果进行了实验验证,这证明了结果之间的良好一致性。数值模拟方法可用于监测Ti6Al4V合金管超频率感应加热过程中的温度分布。这是预测Ti6Al4V合金管感应加热过程的经济有效工具。此外,以往复运动形式在线感应加热是加工Ti6Al4V合金管的可行策略。
    Ti6Al4V alloys have a narrow processing window, which complicates temperature control, especially during large-scale production. Therefore, a numerical simulation and experimental study on the ultrasonic induction heating process of a Ti6Al4V titanium alloy tube were conducted to obtain stable heating. The electromagnetic and thermal fields in the process of ultrasonic frequency induction heating were calculated. The effects of the current frequency and current value on the thermal and current fields were numerically analyzed. The increase in current frequency enhances the skin and edge effects, but heat permeability was achieved in the super audio frequency range, and the temperature difference between the interior and exterior of the tube was less than 1%. An increase in the applied current value and current frequency caused an increase in the tube\'s temperature, but the influence of current was more prominent. Therefore, the influence of stepwise feeding, reciprocating motion, and stepwise feeding superimposed motion on the heating temperature field of the tube blank was evaluated. The coil reciprocating with the roll can maintain the temperature of the tube within the target temperature range during the deformation stage. The simulation results were validated experimentally, which demonstrated good agreement between the results. The numerical simulation method can be used to monitor the temperature distribution of Ti6Al4V alloy tubes during the super-frequency induction heating process. This is an economical and effective tool for predicting the induction heating process of Ti6Al4V alloy tubes. Moreover, online induction heating in the form of reciprocating motion is a feasible strategy for processing Ti6Al4V alloy tubes.
