The Microbiome First Initiative aims to facilitate sustainable healthcare by focusing first and foremost on the human holobiont majority, the microbiome. Understanding how the human microbiome affects not only risk of disease but also human perceptions can help individuals thrive and pave the way for a healthy life course. Following a recent review of Microbiome First Medicine the context of health and safety, this present opinion article considers the role of the human microbiome, particularly the gut microbiome, on pain, sensory perceptions, and the prevention and multimodal management of pain. Microbial dysbiosis can be causative of some forms of immune-inflammatory and neurologic pain and the altered human microbiome can lock in the pain while at the same time interfering with analgesic/opioid therapies. Dysbiotic microbiota can make drug treatments less effective and with opioids, the microbes can significantly increase: For these reasons, it is critical to move beyond simply thinking about the microbiome in dealing with pain to considering the microbiome as central in multimodal pain prevention and management strategies. The microbiome is key in any attempts to change physiology, metabolism, systems biology function, and receptor-based perceptions within the human body.
微生物组优先倡议旨在促进可持续医疗保健,首先关注人类全生物的大多数,即微生物组。了解人类微生物组如何不仅影响疾病风险,而且影响人类认知,可以帮助个人茁壮成长,为健康的生活铺平道路。在最近对《微生物组第一医学》(Microbiome First Medicine)的健康和安全背景进行了综述之后,本观点文章考虑了人类微生物组,特别是肠道微生物组在疼痛、感官感知以及疼痛的预防和多模式管理方面的作用。微生物失调可能导致某些形式的免疫炎症和神经疼痛,而改变的人类微生物组可以锁住疼痛,同时干扰镇痛/阿片类药物治疗。生物失调的微生物群会降低药物治疗的效果,而使用阿片类药物时,微生物会显著增加:出于这些原因,至关重要的是要超越简单地考虑处理疼痛的微生物组,将微生物组视为多模式疼痛预防和管理策略的核心。微生物组是改变人体内生理、代谢、系统生物学功能和基于受体的感知的关键。

Trichomonas vaginalis causes trichomonosis, the number one, non-viral STI, with adverse consequences to women’s reproductive health [1,2]. One of the most immunogenic proteins of T. vaginalis is called P270 of ~270-kDa in size. This P270 protein has tandemly repeated immunogenic DREGRD-epitopes that are detected by the monoclonal antibody (MAb) C20A3 [3-7]. It was discovered by indirect immunofluorescence (IF) that some naturally-occurring isolates had subpopulations of parasites that were heterogeneous in the surface expression of P270 [4]. These isolates had both fluorescent and non-fluorescent organisms. Fluorescence activated cell sorting (FACS) [6] showed that 100 percent fluorescent trichomonads reflecting surface P270 became non-fluorescent. Likewise, sorted non-fluorescent parasites with cytoplasmic P270 reverted to fluorescent organisms with surface P270. It was hypothesized that parasite factors affect P270 synthesis and surface expression. Subsequently it was found that Abstract Trichomonas vaginalis is a flagellated protist and causal agent for trichomonosis, the number one, nonviral sexually transmitted infection (STI). The parasites of all naturally-occurring isolates of T. vaginalis synthesize the immunogenic protein called P270, which is encoded by a single copy gene with numerous tandemly-repeated elements encoding the sequence DREGRD detected by the monoclonal antibody (MAb) C20A3. Isolates have been defined based on the absence (Type I) or presence (Type II) of T. vaginalis dsRNA virus (TVV). Type II TVV+ isolate organisms grown in batch culture have previously been shown to undergo phenotypic variation between surface and non-surface (cytoplasmic) expression of P270 using the MAb C20A3 in immunofluorescence (IF) assays. Type I TVVtrichomonads synthesize lower amounts of P270 that is only found in the cytoplasm. In this study both IF and immunoelectron microscopy (IEM) analysis were performed for the first time to localize P270 on and within both types of trichomonal isolates. IF experiments of Type II TVV+ parasites show whole surface labeling of intact, non-permeabilized organisms and surface and cytoplasmic fluorescence for permeabilized trichomonads. Immunocytochemistry of Type II trichomonads treated with MAb C20A3 presented gold-labeling of P270 throughout the external membrane as well as within peripheral vacuoles. Further, there was no P270 detected within the electron dense hydrogenosome organelles. On the other hand, for Type I TVVpermeabilized organisms, P270 is detected by IF only in the cytoplasm of some parasites, and immunocytochemistry confirmed that no trichomonads had surface P270. These data provide evidence for the first time of compartmentalization and surface localization of P270 among phenotypically varying, Type II TVV+ T. vaginalis compared to the Type I TVVorganisms.
阴道毛滴虫引起滴虫病,这是第一种非病毒性STI,对女性生殖健康有不良影响[1,2]。阴道毛滴虫最具免疫原性的蛋白质之一被称为P270,大小约为270kDa。该P270蛋白具有单克隆抗体(MAb)C20A3[3-7]检测到的串联重复的免疫原性DREGRD表位。通过间接免疫荧光(IF)发现,一些天然存在的分离株具有P270表面表达异质的寄生虫亚群[4]。这些分离物同时具有荧光和非荧光生物体。荧光激活细胞分选(FACS)[6]显示100%的荧光毛滴虫反射表面P270变成非荧光的。同样,具有细胞质P270的分选的非荧光寄生虫恢复为具有表面P270的荧光生物体。据推测,寄生虫因子影响P270的合成和表面表达。随后发现,阴道毛滴虫是一种有鞭毛的原生生物,也是滴虫病的病原体,滴虫病是头号非病毒性传播感染(STI)。阴道毛滴虫所有天然分离株的寄生虫都会合成一种名为P270的免疫原性蛋白,该蛋白由一个单拷贝基因编码,该基因具有许多串联重复的元件,编码单克隆抗体(MAb)C20A3检测到的DREGRD序列。分离物的定义基于阴道双链核糖核酸病毒(TVV)的不存在(I型)或存在(II型)。在免疫荧光(IF)测定中使用MAb C20A3,在分批培养中生长的II型TVV+分离物生物体先前已显示在P270的表面和非表面(细胞质)表达之间经历表型变异。I型TVV毛滴虫合成的P270含量较低,仅在细胞质中发现。在本研究中,首次进行了IF和免疫电子显微镜(IEM)分析,以在两种类型的毛状体分离株上和内部定位P270。II型TVV+寄生虫的实验显示完整的、未透化的生物体的全表面标记以及透化毛滴虫的表面和细胞质荧光。用MAb C20A3处理的II型毛滴虫的免疫细胞化学在整个外膜以及外周液泡内呈现P270的金标记。此外,在电子密集的氢小体细胞器中没有检测到P270。另一方面,对于I型TVV透化的生物体,IF仅在一些寄生虫的细胞质中检测到P270,免疫细胞化学证实没有毛滴虫具有P270表面。这些数据首次提供了P270在表型变化的II型阴道TVV+T.阴道虫与I型阴道TVVorganics相比的区室化和表面定位的证据。

index. COVID-19 disease has economic and financial effects at both macro and micro levels. At the macro level, the economic effects of this pandemic disease have emerged as a shock or economic crisis, meaning that it has affected the financing and economic structure of countries, in other words, the economic pattern and turnover worldwide. At the micro-level, funding sources and health care reimbursement mechanisms in hospitals have been severely affected. In this study, health care repayment and financing systems in the health sector, especially hospitals, were studied. In addition, are retrospective health financing and repayment systems better or prospective repayment systems in times of crisis or economic shock caused by COVID-19 disease? The types of financing mechanisms and current repayment methods, depending on the type of health system as well as other conditions and requirements of each country, have strengths and weaknesses [1-3]. The results of a study (Ahangar et al ., 2021) at Iran University of Medical Sciences show that before and after COVID-19 disease, hospitals with prospective repayment systems (such as DRG, Global, Per Capita mechanisms) compared to hospitals with retrospective repayment systems were more efficient in controlling costs and resources, as well as better managing the quality of hospital care.
指数新冠肺炎疾病在宏观和微观层面都有经济和金融影响。在宏观层面上,这一流行病的经济影响表现为冲击或经济危机,这意味着它影响了各国的融资和经济结构,换句话说,影响了全球的经济模式和营业额。在微观层面,医院的资金来源和医疗保健报销机制受到严重影响。在这项研究中,研究了卫生部门,特别是医院的医疗保健还款和融资系统。此外,在新冠肺炎疾病造成的危机或经济冲击时期,回顾性医疗融资和还款系统是更好还是前瞻性还款系统?融资机制的类型和目前的还款方法,取决于卫生系统的类型以及每个国家的其他条件和要求,有优缺点[1-3]。伊朗医学科学大学的一项研究结果(Ahangar et al.,2021)表明,在新冠肺炎疾病前后,与采用回顾性还款系统的医院相比,采用前瞻性还款系统(如DRG、Global、人均机制)的医院在控制成本和资源方面更有效,并更好地管理医院护理质量。

Gastric Volvulus (GV) is a rare condition characterized by rotation of the stomach 180° around its axis [1]. GV can be either acute or chronic and can lead to various complications including GI obstruction and strangulation. Approximately one third of patients present with acute symptoms [2]. Acute GV is considered a surgical emergency and, if left untreated, has a high rate of mortality. Acute GV is classically characterized by Borchardt’s Triad which consists of unproductive retching, epigastric pain, and inability to pass a Nasogastric (NG) tube [3]. Postprandial vomiting can also be seen. Diagnoses are commonly made with imaging (plain radiograph or CT). In adults, GV is commonly due to diaphragmatic defects. We present a patient with a case of acute gastric volvulus in a 74-year-old female with history of hiatal hernia. The patient was diagnosed via imaging and subsequently underwent surgical reduction of the volvulus and hernia repair.
胃扭转(GV)是一种罕见的疾病,其特征是胃绕轴旋转180°[1]。GV可为急性或慢性,可导致各种并发症,包括胃肠道梗阻和绞杀。大约三分之一的患者出现急性症状[2]。急性GV被认为是一种外科紧急情况,如果不及时治疗,死亡率很高。急性GV的典型特征是Borchardt氏三联征,包括非生产性干呕、上腹痛和无法通过鼻咽喉(NG)管[3]。餐后呕吐也可见。诊断通常通过影像学(平片或CT)进行。在成人中,GV通常是由膈肌缺陷引起的。我们报告一例急性胃扭转患者,一位74岁女性,有裂孔疝病史。患者通过影像学诊断,随后接受了扭转复位和疝修补术。

There is hardly any doubt that our exposure to technical e-smog is increasing. Apart from the increasing natural-cosmicsolar irradiations, which are getting stronger and stronger, but which contain a meaning, because mankind is in a process of transformation, which is strengthened or guided by the cosmos. If you add up the current electromagnetic burdens, you come to a multiplication compared to what we already felt as an imposition 10 or even 20 years ago. And there is no improvement in sight, on the contrary: the more than 30,000 «5G» or soon «6G» satellites that are to be placed by the multi-billionaires (in future dollar trillionaires) are not yet in orbit. The “Internet of Things” is not supposed to make anything happen in an analogue way anymore (as nature does), but to link many billions of devices that are controlled from above and leave hardly any room for human decisions.
毫无疑问,我们接触技术电子游戏的机会正在增加。除了越来越多的自然宇宙太阳辐射,这些辐射越来越强,但也有意义,因为人类正处于一个由宇宙加强或引导的转型过程中。如果你把目前的电磁负担加起来,与10年甚至20年前我们已经感觉到的强加相比,你就会得到一个乘积。相反,看不到任何改善:亿万富翁(未来价值数万亿美元)将要发射的30000多颗“5G”或即将发射的“6G”卫星尚未进入轨道。“物联网”不应该再以模拟的方式(就像大自然一样)让任何事情发生,而是将数十亿个由上面控制的设备连接起来,几乎没有给人类决策留下任何空间。

Despite therapeutic advances, infectious complications continue to play a significant role in the clinical course of patients with CLL. Cerebral toxoplasmosis is among the most common CNS infections in immunocompromised patients. Toxoplasma gondii can cause a life threatening CNS or disseminated infection, usually due to reactivation of a latent infection. We describe here the case of a 76 year-old man who developed toxoplasmic encephalitis after a treatment with obinutuzumab-chlorambucil for a CLL. He was admitted to the emergency room for confusion, agitation, Brocca aphasia, diplopia and left mydriasis seven months after the end of treatment with obinutuzumab-chlorambucil. Brain MRI showed at least eight intra-axial supra-tentorial lesions. A brain biopsy was performed and showed a florid toxoplasmosis. Rapidly, treatment with TMP-SMX was started and an improvement in the patient neurological condition was gradually observed. This is the first case of cerebral toxoplasmosis described after treatment with obinutuzumab-chlorambucil in a patient with CLL.
尽管治疗取得了进展,但感染性并发症仍然在CLL患者的临床过程中发挥着重要作用。脑弓形虫病是免疫功能受损患者最常见的中枢神经系统感染之一。弓形虫可引起危及生命的中枢神经系统或播散性感染,通常是由于潜伏感染的再激活。我们在这里描述了一个76岁的男性病例,他在接受奥比努珠单抗氯丁二烯治疗CLL后患上了弓形虫脑炎。在奥比努珠单抗-氯霉素治疗结束七个月后,他因意识模糊、烦躁不安、Brocca失语症、复视和左散瞳住进了急诊室。脑MRI显示至少8处轴内幕上病变。进行了脑部活组织检查,结果显示有花形弓形虫病。很快,开始使用TMP-SMX进行治疗,并逐渐观察到患者神经状况的改善。这是第一例CLL患者在接受奥比努珠单抗-氯丁二烯治疗后出现的脑弓形虫病。

Congenital diaphragmatic hernia a rare congenital malformation which often requires surgical interventions. The surgery is not an emergency, and it can be done within days with planned preoperative optimisation. We present a case of a premature neonate presented with co-existence of left side diaphragmatic hernia with imperforate anus. Presence of imperforate anus prevents the passage of meconium leading to distention of bowel increasing the resistance inside the left hemithorax. Therefore, an urgent repair of the diaphragmatic hernia with colostomy formation was done under general anaesthesia after 48 hours of birth. Patient was managed in a paediatric intensive care unit both pre and post operative period. Even though the post operative period was complicated with a broncopneumonia and a pleural effusion, he was discharged from ICU 20 days after the procedure.
先天性膈疝是一种罕见的先天性畸形,通常需要手术干预。手术不是紧急情况,可以在几天内完成,并计划进行术前优化。我们报告一例早产新生儿并发左侧膈疝及肛门闭锁。肛门闭锁可阻止胎粪通过,导致肠道扩张,增加左半胸内的阻力。因此,在分娩48小时后,在全身麻醉下进行了带结肠造口的膈疝紧急修复。患者在术前和术后均在儿科重症监护室接受治疗。尽管术后并发支气管肺炎和胸腔积液,但他在手术后20天就从重症监护室出院了。
