The incidence of nosocomial infections or, in other words, healthcare-associated infections, is bigger in developing countries. World Health Organisation (WHO) estimates that as much as 15% of all hospitalized patients will contract an infection related to medical procedures. Nosocomial pathogens are represented by viruses, bacteria, fungal and parasites. The pathway of contamination is different and these could be represented by environmental sources, healthcare staff or other infected patients. Over the past decades, Clostridium difficile infection became more and more frequent in hospitalized patients. Unfortunately, not all the cases are reported and some of the patients are diagnosed with time after discharge, in other medical services. Gynecologic surgery, as well as obstetric patients already, have numerous risk factors for infection. The addition of Clostridium difficile infection in these patients could be catastrophal. Thus, the reported rising incidence of Clostridium difficile infection in gynecological and obstetric patients should be alarming and unacceptable since the pathogen is transmitted from one infected patient to another through unproperly cleaned medical staff hands. Although the main risk factor for Clostridium difficile infection is the use of broad-spectrum antibiotics, the treatment is also antibiotic. Thus, the overuse of prophylactic antibiotherapy in patients undergoing gynecologic surgery should not be recommended.s.
在发展中国家,医院感染,或者换句话说,医疗保健相关感染的发生率更高。世界卫生组织(WHO)估计,多达15%的住院患者将感染与医疗程序有关的感染。医院病原体包括病毒、细菌、真菌和寄生虫。污染的途径是不同的,这些途径可以由环境来源、卫生保健人员或其他受感染的患者来代表。在过去的几十年里,艰难梭菌感染在住院患者中变得越来越频繁。不幸的是,并非所有病例都得到了报告,有些患者在出院后在其他医疗机构得到了诊断。妇科手术以及产科患者已经有许多感染的危险因素。在这些患者中增加艰难梭菌感染可能是灾难性的。因此,报告的艰难梭菌感染在妇科和产科患者中的发病率上升应该是令人震惊和不可接受的,因为病原体是通过未适当清洁的医务人员的手从一个受感染的患者传播到另一个。虽然艰难梭菌感染的主要危险因素是使用广谱抗生素,但治疗也是抗生素。因此,不建议妇科手术患者过度使用预防性抗生素治疗。

New drug products that can effectively improve the ability of supportive care to reduce the risk of ARDS or its mortality rate in COVID-19 patients are urgently needed. Rejuveinix (RJX) is a formulation of physiologically compatible active ingredients, including several vitamins, such as ascorbic acid, cyanocobalamin, thiamine hydrochloride, riboflavin 5' phosphate, niacinamide, pyridoxine hydrochloride, calcium d-pantothenate that exhibited promising anti-ARDS activity in animal models of sepsis and ARDS as well as clinical studies in patients with sepsis, septic shock, and ARDS. RJX could favorably affect the patient journey in COVID-19 at multiple stages, including (i) prevention of progression of mild disease, (ii) faster resolution of ARDS, prevention of multi-organ failure, and reduction of case mortality during respiratory failure, and (iii) improved long-term healing after recovery. Here we are reporting the critical design elements for a two-cohort, two-part placebo-controlled, and double-blind Phase II study of RJX in COVID-19 patients.
迫切需要能够有效提高支持护理能力以降低COVID-19患者ARDS风险或死亡率的新药。Rejuveinix (RJX)是一种生理相容的活性成分制剂,包括几种维生素,如抗坏血酸、氰钴胺素、盐酸硫胺素、5′磷酸核黄素、烟酰胺、盐酸吡哆醇、d-泛酸钙,在败血症和ARDS动物模型以及败血症、感染性休克和ARDS患者的临床研究中显示出有希望的抗ARDS活性。RJX可以在多个阶段对COVID-19患者的旅程产生有利影响,包括(i)预防轻度疾病的进展,(ii)加快ARDS的解决,预防多器官衰竭,降低呼吸衰竭期间的病例死亡率,以及(iii)改善恢复后的长期愈合。在这里,我们报告了RJX在COVID-19患者中的双队列、两部分安慰剂对照、双盲II期研究的关键设计要素。

RJX is an Intravenous (IV) formulation of known physiologically compatible compounds that is being developed for more effective supportive therapy of patients with sepsis, including COVID-19 patients with viral sepsis and Acute Respiratory Distress Syndrome (ARDS). The RJX formulation is a solution of buffered acid products, electrolyte components, and vitamins, including ascorbic acid, cyanocobalamin, thiamine hydrochloride, riboflavin 5' phosphate, niacinamide, pyridoxine hydrochloride, and calcium d-pantothenate, and magnesium sulfate heptahydrate, a mineral with a negative oxidation-reduction potential. The components of RJX exhibited promising activity in clinical studies involving ARDS patients and/or non-clinical studies in animal models of ARDS. The published data from these clinical and non-clinical studies provided the medical-scientific rationale for our clinical development strategy for RJX and a clinical study in COVID-19 patients.

Introduction: Obesity has become a serious global epidemic which poses a major health hazard to the human being. Globally, changing trends such as high intake of fast food, sedentary lifestyle, industrialization, and urbanization are significant key factors that are leading to an increase in the burden of overweight and obesity. The rise in obesity has also been linked been with depression and an increase in stigma and discrimination towards such obese individuals. Objectives: The aim of the present study is to assess health behavior and depression among overweight/obese adults in Pakistan. Methodology: A descriptive cross-sectional study design was used. Two different data collection tools i.e. Health Behavior Questionnaire (HBQ) and Hospital Anxiety and Depression Score (HADS) were used. The questionnaire was self-administered to a sample of 382 overweight/obese adults residing in Islamabad and Rawalpindi Pakistan calculated by using Raosoft and selected by convenience sampling technique. After data collection, data were coded and analyzed statistically by using Mann-Whitney and Kruskal Wallis Test. Results: The results of the study highlighted that the healthy eating factor score and amount ate factor score was significantly high among females with a p-value of 0.029 and 0.008 respectively where the amount of sleep factor score with (p=0.000) was significantly high among males with a p-value of 0.001. The study results showed that emotional eating factor score, amount eaten factor score, convenience food factor score, TV watching factor score, travel to work factor score, and early maturation factor score was significantly high among adults with an age group of 48-57 years. Conclusion: This study concluded that health behavior is linked with gender, marital status, age, physical activity, and educational qualification of adults whereas stress was associated with physical activity and qualification of adults. Females had unhealthy eating habits where males have bad sleep patterns. The stress factor has an inverse relationship with qualification and physical activity. Healthcare professionals should design innovative interventions to improve healthy eating behavior and reduce depression and stigma associated with obesity.
肥胖症已成为一种严重的全球性流行病,对人类健康构成重大危害。在全球范围内,诸如高摄入快餐、久坐不动的生活方式、工业化和城市化等不断变化的趋势是导致超重和肥胖负担增加的重要关键因素。肥胖人数的增加还与抑郁症以及对这类肥胖者的羞辱和歧视的增加有关。目的:本研究的目的是评估巴基斯坦超重/肥胖成年人的健康行为和抑郁。方法:采用描述性横断面研究设计。采用健康行为问卷(HBQ)和医院焦虑抑郁评分(HADS)两种不同的数据收集工具。问卷采用方便抽样法,对居住在巴基斯坦伊斯兰堡和拉瓦尔品第的382名超重/肥胖成年人自行进行问卷调查。数据收集完成后,采用Mann-Whitney and Kruskal Wallis检验对数据进行编码和统计分析。结果:研究结果表明,健康饮食因子得分和数量饮食因子得分在女性中显著较高,p值分别为0.029和0.008,而数量睡眠因子得分(p=0.000)在男性中显著较高,p值为0.001。研究结果表明,48 ~ 57岁的成年人情绪饮食因子得分、进食量因子得分、方便食品因子得分、看电视因子得分、上班出行因子得分和早熟因子得分均较高。结论:健康行为与成年人的性别、婚姻状况、年龄、身体活动和教育程度有关,而压力与成年人的身体活动和教育程度有关。女性有不健康的饮食习惯,而男性有糟糕的睡眠模式。应激因子与学历和体力活动呈负相关。医疗保健专业人员应该设计创新的干预措施,以改善健康的饮食行为,减少与肥胖相关的抑郁和耻辱。

OBJECTIVES. We wanted to explore the knowledge and attitudes of pregnant women and women after giving birth to oral health. Likewise, we wanted to determine whether there was any awareness of oral hygiene during pregnancy in the aforementioned population. Our aim was to establish the correlation between oral hygiene habits in relation to age, level of education and place of residence (urban / rural) and to determine the importance of the role of experts in further education of the patient. STUDY DESIGN. A cross-sectional study. PATIENTS AND METHODS. The subjects were patients admitted to the department of maternal and puerpera in the maternity ward of the General Hospital Zabok and Croatian veterans in the period from 1 December 2016 till 15 February 2017. Data for statistical analysis were obtained on the basis of an anonymous questionnaire of 15 questions. RESULTS. Nearly half of pregnant women and women after delivery (49%) believe that oral hygiene does not affect the outcome of pregnancy. In Planned Parenthood pregnancy 70% of women with the lowest levels of education are not going to control dental examinations. Over 90% of highly educated respondents used additional oral hygiene products, while only 20% of women with low levels of education used additional products. The results showed that 71% of women thought they had not received enough oral health information from their doctor. Also, in 60% of respondents, primary data on oral hygiene and health were not received by health professionals but from other sources. CONCLUSION. The obtained data show that almost half of the respondents did not develop the habit of awareness of the need for oral hygiene. The prevalence of monitoring the level of education but are weaker indicators correlate with low skill levels. The emphasis of the modern approach to the prevention of, and given that over half of the surveyed women does not the necessary knowledge of oral health opens space for continuing education and the promotion of information programs by the health system.
目标。我们想探讨孕妇和产后妇女对口腔健康的认识和态度。同样,我们想确定在上述人群中是否有任何怀孕期间的口腔卫生意识。我们的目的是建立口腔卫生习惯与年龄、教育水平和居住地(城市/农村)之间的相关性,并确定专家在患者继续教育中的重要性。研究设计。横断面研究。患者和方法。研究对象是2016年12月1日至2017年2月15日期间在Zabok总医院产科病房的产妇和产褥部住院的患者和克罗地亚退伍军人。统计分析的数据是在15个问题的匿名问卷的基础上获得的。结果。近一半的孕妇和产后妇女(49%)认为口腔卫生不影响妊娠结局。在计划生育中,70%的受教育程度最低的妇女不去控制牙科检查。超过90%受过高等教育的受访者使用了额外的口腔卫生产品,而受教育程度较低的女性中只有20%使用了额外的产品。结果显示,71%的女性认为她们没有从医生那里得到足够的口腔健康信息。此外,在60%的答复者中,有关口腔卫生和健康的原始数据不是由卫生专业人员而是从其他来源获得的。结论。获得的数据显示,几乎一半的受访者没有养成意识到口腔卫生需要的习惯。普遍监测教育水平但较弱的指标与低技能水平相关。强调现代预防方法,并考虑到超过一半的被调查妇女不具备必要的口腔健康知识,为卫生系统继续教育和促进信息方案开辟了空间。

Selectively targeting TGF-β with Trabedersen/OT-101 in treatment of evolving and mild ards inCOVID-19 Trabedersen/OT-101选择性靶向TGF-β治疗新冠肺炎进展和轻度ards

Based on the role of TGF- β in the immunopathology of ARDS, we and others have proposed the use of TGF-β inhibitors for the treatment of COVID-19 pneumonia and ARDS. TGF-b targeting is employed as a strategy to stimulate the immune system of advanced-stage cancer patients in an attempt to overcome the immunosuppression and T-cell exhaustion within the tumor microenvironment. Nevertheless, we do not anticipate any worsening of existing ARDS or Cytokine Storm/Cytokine Release Syndrome (CRS) of COVID-19 patients as a treatment-emergentt complication with our contemplated use of the anti-TGF-β RNA therapeutic OT-101. That is because (i) inhibitors of TGF-β signaling are not associated with ARDS, Cytokine Storm/CRS, or systemic capillary leak, (ii) OT-101 did not cause any pulmonary toxicity, non-infectious pneumonitis, CRS, systemic or pulmonary capillary leak or ARDS in any of the 61 patients with advanced solid tumors enrolled in Phase I/II study (ClinicalTrials.gov identifier: NCT00844064) who received much longer periods of OT-101 therapy, and (iii) OT-101 did not cause in human subjects an elevation of TNF-α, IL-6 or IL-10 levels associated with CRS and ARDS in COVID-19 patients - likewise, OT-101 did not induce production of these inflammatory cytokines in cultures of human white blood cells. We postulate that because of the significance of the TGF-β pathway on the development of ARDS and T cell exhaustion, treatment with OT-101 may prevent the progression of evolving or mild ARDS and help facilitate the recovery of lymphocytopenia and T-cell exhaustion in COVID-19 patients.
基于TGF-β在ARDS免疫病理中的作用,我们等人提出使用TGF-β抑制剂治疗COVID-19肺炎和ARDS。TGF-b靶向是一种刺激晚期癌症患者免疫系统的策略,试图克服肿瘤微环境内的免疫抑制和t细胞衰竭。然而,我们预期使用抗tgf -β RNA治疗药物OT-101不会导致COVID-19患者现有ARDS或细胞因子风暴/细胞因子释放综合征(CRS)的恶化。这是因为(i) TGF-β信号的抑制剂与急性呼吸窘迫综合征、细胞因子风暴/CRS或全身性毛细血管渗漏无关;(ii) OT-101在参加i / ii期研究的61例晚期实体瘤患者中没有引起任何肺毒性、非感染性肺炎、CRS、全身性或肺部毛细血管渗漏或急性呼吸窘迫综合征。NCT00844064)接受更长时间的OT-101治疗,并且(iii) OT-101不会导致人类受试者中与COVID-19患者CRS和ARDS相关的TNF-α, IL-6或IL-10水平升高-同样,OT-101不会诱导人类白细胞培养物中这些炎症细胞因子的产生。我们推测,由于TGF-β通路在ARDS发展和T细胞衰竭中的重要作用,使用OT-101治疗可能会阻止进展或轻度ARDS的进展,并有助于促进COVID-19患者淋巴细胞减少和T细胞衰竭的恢复。

That is because (i) inhibitors of TGF-β signaling are not associated with ARDS, Cytokine Storm/CRS, or systemic capillary leak, (ii) OT-101 did not cause any pulmonary toxicity, non-infectious pneumonitis, CRS, systemic or pulmonary capillary leak or ARDS in any of the 61 patients with advanced solid tumors enrolled in Phase I/II study (ClinicalTrials.gov identifier: NCT00844064) who received much longer periods of OT-101 therapy, and (iii) OT-101 did not cause in human subjects an elevation of TNF-α, IL-6 or IL-10 levels associated with CRS and ARDS in COVID-19 patients - likewise, OT-101 did not induce production of these inflammatory cytokines in cultures of human white blood cells. We postulate that because of the significance of the TGF-β pathway on the development of ARDS and T cell exhaustion, treatment with OT-101 may prevent the progression of evolving or mild ARDS and help facilitate the recovery of lymphocytopenia and T-cell exhaustion in COVID-19 patients.","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"14 1","pages":"35-44"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85606027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Midostaurin is a non-specific FLT3 inhibitor that showed anti-leukemic activity against both FLT3 mutated as well as unmutated Acute Myeloid Leukemia (AML) in early phase studies. Panobinostat, a potent oral pan-acetylase inhibitor had also shown significant anti-leukemic signals in early phase studies. In the preclinical study, our group had previously reported synergistic anti-leukemic activity when an FLT3 inhibitor was used in combination with an HDAC inhibitor in vitro as well as in vivo animal study. The current study is our first bench-to-bedside study to further evaluate this combination therapy in AML patients. Method: Elderly AML who were either newly diagnosed and declined Hypomethylating Agent (HMA) or who failed HMA, MDS-RAEB-2, and relapsed refractory AML who were unfit for intensive chemotherapy or have no other treatment option were eligible regardless of FLT3 mutation status. The classical 3+3 dose escalation method was applied. Dose level 1 for Midostaurin was 50 mg bd and Panobinostat was 10 mg 3 times per week. Dose escalations were planned with only one drug escalation at a time on every level. Midostaurin was administered daily as a continuous cycle while Panobinostat was given for the first 3 weeks of a 4 weeks cycle. Dose-limiting toxicities were defined as grade 3 or more non-haematologic toxicities occurring within the first cycle. Chronic toxicity is defined as recurrent or persistent adverse events that are possibly related to investigational products. Response assessments were done at post cycle 2 and cycle 4. Concomitant treatment with hydroxyurea was allowed up to cycle 1 day 14 to control leukocytosis if needed. Results: A total of 7 patients have been recruited with a median age of 71 years old (range: 47 to 82 years). 2 patients had MDS-RAEB2, one with Acute myelomonocytic leukemia, 3 had AML with myelodysplasia-related changes (AML-MRC) and one with de novo FLT3-ITD AML. One of the AML-MRC had FLT3-ITD mutation and another had FLT3-TKD mutation. 4 out of 7 had prior HMA therapy, the remaining three were treatment naive. 2 patients were not evaluable for DLT and response assessment due to progressive disease during cycle 1. 2 completed 2 cycles, the other 3 completed 4, 5 and 9 cycles respectively. No DLT was observed within cycle 1. Significant grade 1-2 treatment emerging adverse events were anorexia (4/5), fatigue (3/5), nausea (2/5), and dysgeusia (2/5). These toxicities persist beyond cycle 1 with increasing frequency. Grade 2 fatigue was observed in 4 patients, grade 2 anorexia in 4 patients, grade 1 dysgeusia in 4 patients, and grade 3 lipase elevation in one patient. 4 out of 5 patients developed severe grade 4 thrombocytopenia requiring regular platelet transfusion. Two had baseline grade 4 thrombocytopenia but the severity worsen after 1 cycle of treatment. These were thought to be chronic toxicities because the symptoms were largely resolved or improved during dose interruptions. In view
简介:midosulin是一种非特异性FLT3抑制剂,在早期研究中对FLT3突变和非突变的急性髓性白血病(AML)都显示出抗白血病活性。Panobinostat是一种有效的口服泛乙酰化酶抑制剂,在早期研究中也显示出显著的抗白血病信号。在临床前研究中,我们小组先前在体外和体内动物研究中报道了FLT3抑制剂与HDAC抑制剂联合使用时的协同抗白血病活性。目前的研究是我们第一个进一步评估这种联合治疗在AML患者中的临床试验。方法:无论FLT3突变状态如何,新诊断的低甲基化剂(HMA)下降或HMA, MDS-RAEB-2失败的老年AML以及不适合强化化疗或没有其他治疗选择的复发难治性AML均符合条件。采用经典的3+3剂量递增法。米多斯汀的一级剂量为每天50毫克,帕比诺他为10毫克,每周3次。剂量递增计划在每个水平上每次只增加一种药物。米多斯汀作为一个连续的周期每天给药,而帕比诺他在4周周期的前3周给药。剂量限制性毒性定义为第一个周期内发生的3级或以上非血液学毒性。慢性毒性被定义为可能与研究产品相关的复发性或持续性不良事件。在第2和第4周期后进行反应评估。如果需要,羟基脲的联合治疗可以持续到第14天,以控制白细胞增多。结果:共招募了7例患者,中位年龄为71岁(范围:47 - 82岁)。2例为MDS-RAEB2, 1例为急性髓细胞白血病,3例为AML伴骨髓增生异常相关改变(AML- mrc), 1例为新生FLT3-ITD AML。AML-MRC 1例发生FLT3-ITD突变,1例发生FLT3-TKD突变。7人中有4人先前接受过HMA治疗,其余3人未接受治疗。2例患者在第1周期由于疾病进展而无法评估DLT和反应评估。2名完成2个周期,其余3名分别完成4、5和9个周期。第1周期未见DLT。显著的1-2级治疗不良事件为厌食(4/5)、疲劳(3/5)、恶心(2/5)和发音困难(2/5)。这些毒性在第1周期之后持续存在,频率越来越高。4例患者出现2级疲劳,4例患者出现2级厌食症,4例患者出现1级读写困难,1例患者出现3级脂肪酶升高。5例患者中有4例发生严重的4级血小板减少症,需要定期输注血小板。2例基线为4级血小板减少,但治疗1个周期后严重程度加重。这些被认为是慢性毒性,因为在中断剂量期间症状基本消失或改善。鉴于显著的慢性毒性,没有进一步增加剂量,剂量水平1将在扩大队列中进一步评估。7人中有5人进行了周期2后反应评估。1例FLT3-TKD患者达到CRi, 1例AML-MRC显示50%的细胞减少,其余3例病情稳定。完成CRi的患者在完成6个周期后因疲劳、厌食、严重4级血小板减少伴胃肠道出血退出研究。他的输血需求也减少了。直到2019年2月(退出研究16个月后),他的病情一直稳定,没有接受进一步的抗白血病治疗,当时他复发了。患者病情稳定,在第10周期因并发急性胆囊炎和败血症而死亡。其余5例因病情进展而死亡。结论:尽管在第1周期内未观察到DLT,但观察到明显的慢性毒性,如疲劳和厌食。在5例可评估的患者中观察到有限的抗白血病活性。需要进一步探索不同给药方案或与其他抗白血病药物联合使用,以提高耐受性和疗效。

Introduction: Diagnosing Spondylodiscitis (SD) can be challenging in clinical practice with highly variable outcomes. The aim of this study is to retrospectively analyze the clinical, laboratory, imaging findings of patients with SD treated at our hospital between January 2017 and December 2018. We also evaluated the SD evolution during a short follow-up at 4 and 6 weeks. Methods: The epidemiological, clinical, microbiological, laboratory findings (White Blood Count (WBC), C-Reactive Protein (CRP) and Erythrocyte Sedimentation rate (ESR)), Imaging (CT/MRI) and treatment data of 38 patients with SD were studied retrospectively. The laboratory findings (CRP, ESR) and the CT/MRI examinations during the follow-ups at 4 and 6 weeks were evaluated. Based on imaging (CT/MRI) we divided SD into the following 5 types based on morphological features observed: spondylitis or discitis (ST/DS), SD, SD with paravertebral abscesses (SD-PA), SD with epidural abscess (SD-EP) and SD with paravertebral and epidural abscesses (SD-PEA). Results: The most common complaint was pain (95%) and the main comorbidity was septicemia (42%). Staphylococcus aureus was found in 45% of the cases. The WBC was elevated in 32% of the patients. Both the CRP and ESR decreased during the follow-up. SD was found in 31% of the cases, SD-PA in 26% of the cases, ST/DS in 19% of the cases, SD-PEA in 13% of the cases and SD-EP in 11% of the cases. At the follow-up at week 4, SD-PA, SD-EP and SD-PEA had decreased and were found respectively in 21%, 5% and 5% of the cases. In the follow-up at week 6, SD-PA, SD-EP and SD-PEA were found respectively in 10%, 8% and 3% of the patients. Conservative treatment with antibiotic therapy was applied in 63% of the cases. Surgical treatment was given to 21% of the patients and an interventional procedure was done on 16% of the patients. Conclusion: SD diagnosis and management continues to be based on a multidisciplinary approach. Re-imaging in the critical period of 4-6 weeks with the monitoring of systemic inflammatory markers can be a good follow-up strategy.
简介:诊断脊柱炎(SD)在临床实践中具有挑战性,结果变化很大。本研究的目的是回顾性分析2017年1月至2018年12月在我院治疗的SD患者的临床、实验室和影像学表现。我们还在4周和6周的短期随访中评估了SD的演变。方法:回顾性分析38例SD患者的流行病学、临床、微生物学、实验室表现(白细胞计数(WBC)、c反应蛋白(CRP)、红细胞沉降率(ESR))、影像学(CT/MRI)及治疗资料。在随访的第4周和第6周评估实验室检查(CRP、ESR)和CT/MRI检查。根据影像学(CT/MRI)观察到的形态学特征,我们将SD分为以下5种类型:脊柱炎或椎间盘炎(ST/DS)、SD、SD合并椎旁脓肿(SD- pa)、SD合并硬膜外脓肿(SD- ep)和SD合并椎旁及硬膜外脓肿(SD- pea)。结果:最常见的主诉为疼痛(95%),主要合并症为败血症(42%)。其中,金黄色葡萄球菌占45%。32%的患者白细胞升高。随访期间CRP和ESR均下降。SD占31%,SD- pa占26%,ST/DS占19%,SD- pea占13%,SD- ep占11%。第4周随访时,SD-PA、SD-EP和SD-PEA下降,分别占21%、5%和5%。在第6周的随访中,SD-PA、SD-EP和SD-PEA的发生率分别为10%、8%和3%。63%的病例采用抗生素保守治疗。21%的患者接受了手术治疗,16%的患者接受了介入性手术。结论:SD的诊断和治疗仍然以多学科方法为基础。在关键时期4-6周重新成像并监测全身炎症标志物是一个很好的随访策略。

Mitochondrial job and creation of toxic mix by antibiotic Mitochondria, a primitive endosymbiotic bacteria, related to extant SARII marine bacteria and Rickettsias, in eukaryotes is responsible for Oxidative Phosphorylation (OP) and ATP and NAD production, when exposed to clinically equivalent doses of antibiotics that target bacteria (cipromycin, ampicillin, kanamycin), exhibited a decline in glutathione titre, an increase in Reactive Oxygen (ROS) and an increase in lipid peroxide [1,2]. Modes of action of antibiotics on mitochondria and microbiome 1. Quinolones: Commonly prescribed antibacterial organofluorine compounds that act by inhibition of bacterial DNA synthesis and result in rapid cell death [3]. They could be expected to do collateral damage to mitochondria and the human microbiome. This group contains Ofloxacin, Norfloxacin (Noroxin), Ciprofloxacin (Cipro), Moxifloxacin (Avelox)
真核生物中的线粒体是一种原始的内共生细菌,与现存的SARII海洋细菌和立克次体有关,负责氧化磷酸化(OP)、ATP和NAD的产生。当暴露于临床等量的靶向细菌抗生素(环丙霉素、氨苄西林、卡那霉素)时,会表现出谷胱甘肽滴度下降、活性氧(ROS)增加和过氧化脂质增加[1,2]。抗生素对线粒体和微生物组的作用方式喹诺酮类:常用的抗菌有机氟化合物,通过抑制细菌DNA合成而导致细胞快速死亡。它们可能会对线粒体和人类微生物群造成附带损害。该组含有氧氟沙星、诺氟沙星(诺罗辛)、环丙沙星(环普罗)、莫西沙星(阿维洛)

Introduction: DKA has long been considered and studied as a complication of type 1 diabetes in children, only a few studies showed the magnitude of the DKA among adults and type 2 DM. Objective: To evaluate the burden of adult admissions with DKA in Salmaniya Medical Complex-Bahrain, and try to identify the different trends. Methods: Retrospective study; data collected from medical records of adult patients, age 14 and above, who were admitted to Salmaniya medical complex with DKA in the period between January 2017 to December 2018 and fulfilled our inclusion criteria. The data included basic demographic information, and progress during admission. Results: We included 224 DKA admissions, the median age was 31.2 years, the rate of readmission was high as 33 patients were responsible for 102 admissions, mostly type 1 (93.5%) (p-value=0.011). In the analysis, we divided them into subgroups of new diagnoses 32 (14.3%), type 1 DM 147 (65.6%), type 2 DM 45 (20.1). Type 2 DM had higher comorbidities 25 (55.6%) (p-value<0.006), and higher antibiotic use 30 (66.7%) (p-value=<0.0001). Type 2 DM with DKA had 9.5 times higher risk for mortality compared to Type 1 DM with DKA, interestingly type 1 DM group had significantly lower hospital length of stay than the rest groups (2.7 vs 5.3 and 5.0) days. The total mortality was 5 (2.2%) Conclusion: DKA admissions are associated with significant morbidity, effort must be targeted at reducing the number of admissions, and mortality, possibly by enforcing health education, offering psychosocial support, creating policies to ensure continuous insulin supply and involving the primary care centers in the management of hyperglycemia and early DKA.
长期以来,DKA一直被认为是儿童1型糖尿病的并发症,只有少数研究显示了成人和2型糖尿病的DKA的严重程度。目的:评估巴林Salmaniya医疗中心成人DKA入院负担,并试图确定不同的趋势。方法:回顾性研究;数据收集自2017年1月至2018年12月期间Salmaniya医疗中心收治的14岁及以上患有DKA的成年患者的医疗记录,并符合我们的纳入标准。数据包括基本人口统计信息和入院期间的进展情况。结果:我们纳入了224例DKA入院患者,中位年龄为31.2岁,再入院率高,33例患者负责102例入院,以1型为主(93.5%)(p值=0.011)。在分析中,我们将他们分为新诊断的32例(14.3%),1型DM 147例(65.6%),2型DM 45例(20.1%)。2型糖尿病患者合并症较多(55.6%)(p值<0.006),抗生素使用较多(66.7%)(p值<0.0001)。2型糖尿病合并DKA的死亡率是1型糖尿病合并DKA的9.5倍,有趣的是,1型糖尿病组的住院时间明显低于其他组(2.7 vs 5.3和5.0)天。结论:DKA入院与显著的发病率相关,必须努力减少入院人数和死亡率,可能通过加强健康教育,提供社会心理支持,制定政策以确保持续的胰岛素供应,并让初级保健中心参与高血糖和早期DKA的管理。
