Application of evidence-based medicine methods in integrative oncology research

To present the advances of evidence-based medicine and clinical research methodology in integrative oncology,we conducted a literature review of real-world studies of traditional Chinese medicine(TCM)in cancer care and summarized the available evidence.Pragmatic randomized controlled trials(pRCTs)and clinical registry studies are becoming more popular as they could compensate for the limitations of RCTs.Many RCTs of TCM for cancer treatment as well as systematic reviews have been published.The most investigated therapies are based on acupuncture,Chinese herbal compounds,and Chinese patent medicines.Acupuncture has a significant advantage in relieving cancer-related symptoms.Published studies focus more on improving clinical symptoms and laboratory indicators.However,the patient's quality of life deserves more attention.

The artificial intelligence evidence-based medicine pyramid

Several studies exist in the literature regarding the exploitation of artificial intelligence in intensive care.However,an important gap between clinical research and daily clinical practice still exists that can only be bridged by robust validation studies carried out by multidisciplinary teams.

Irritable bowel syndrome: Pathogenesis, diagnosis, treatment, and evidence-based medicine

Irritable bowel syndrome (IBS) is a chronic and debilitating functional gastrointestinal disorder that affects 9%-23% of the population across the world. The percentage of patients seeking health care related to IBS approaches 12% in primary care practices and is by far the largest subgroup seen in gastroenterology clinics. It has been well documented that these patients exhibit a poorer quality of life and utilize the health care system to a greater degree than patients without this diagnosis. The pathophysiology of IBS is not clear. Many theories have been put forward, but the exact cause of IBS is still uncertain. According to the updated ROME III criteria, IBS is a clinical diagnosis and presents as one of the three predominant subtypes: (1) IBS with constipation (IBS-C); (2) IBS with diarrhea (IBS-D); and (3) mixed IBS (IBS-M); former ROME definitions refer to IBS-M as alternating IBS (IBS-A). Across the IBS subtypes, the presentation of symptoms may vary among patients and change over time. Patients report the most distressing symptoms to be abdominal pain, straining, myalgias, urgency, bloating and feelings of serious illness. The complexity and diversity of IBS presentation makes treatment difficult. Although there are reviews and guidelines for treating IBS, they focus on the efficacy of medications for IBS symptoms using high-priority endpoints, leaving those of lower priority largely unreported. Therefore, the aim of this review is to provide a comprehensive evidence-based review of the diagnosis, pathogenesis and treatment to guide clinicians diagnosing and treating their patients.

Problems faced by evidence-based medicine in evaluating lymphadenectomy for gastric cancer

Gastric cancer surgical management differs between Eastern Asia and Western countries. Extended lymphadenectomy (D2) is the standard of care in Japan and South Korea since decades, while the majority of United States patients receive at most a limited lymphadenectomy (D1). United States and Northern Europe are considered the scientific leaders in medicine and evidence-based procedures are the cornerstone of their clinical practice. However, surgeons in Eastern Asia are more experienced, as there are more new cases of gastric cancer in Japan (107898 in 2012) than in the entire European Union (81592), or in South Korea (31269) than in the entire United States (21155). For quite a long time evidence-based medicine (EBM) did not solve the question whether D2 improves long-term prognosis with respect to D1. Indeed, eastern surgeons were reluctant to perform D1 even in the frame of a clinical trial, as their patients had a very good prognosis after D2. Evidence-based surgical indications provided by Western trials were questioned, as surgical procedures could not be properly standardized. In the present study we analyzed indications about the optimal extension of lymphadenectomy in gastric cancer according to current scientific literature (2008-2012) and surgical guidelines. We searched PubMed for papers using the key words “lymphadenectomy or D1 or D2” AND “gastric cancer” from 2008 to 2012. Moreover, we reviewed national guidelines for gastric cancer management. The support to D2 lymphadenectomy increased progressively from 2008 to 2012: since 2010 papers supporting D2 have achieved a higher overall impact factor than the other papers. Till 2011, D2 was the procedure of choice according to experts’ opinion, while three meta-analyses found no survival advantage after D2 with respect to D1. In 2012-2013, however, two meta-analyses reported that D2 improves prognosis with respect to D1. D2 lymphadenectomy was proposed as the standard of care for advanced gastric cancer by Japanese National Guidelines since 1981 and was adopted as the standard procedure by the Italian Research Group for Gastric Cancer since the Nineties. D2 is now indicated as the standard of surgical treatment with curative intent by the German, British and ESMO-ESSO-ESTRO guidelines. At variance American NCCN guidelines recommend a D1+ or a modified D2 lymph node dissection. In conclusion, D2 lymphadenectomy, originally developed by Eastern surgeons, is now becoming the procedure of choice also in the West. In gastric cancer surgery EBM is lagging behind national guidelines, rather than preceding and orienting them. To eliminate this lag, EBM should value to a larger extent Eastern Asian literature and should evaluate not only the quality of the study design but also the quality of surgical procedures.

The concept of narrative evidence-based medicine and shared decision-making in traditional Chinese medical practice

For the explosive development of emerging diagnostic and therapeutic technologies brought by the advancement of precision medicine strategy, shared decision-making could improve the quality of clinical decision-making and promote the transformation of clinical research evidence in TCM. Paying attention to patients＇ narrative needs and strengthening medical humanistic concerns could improve clinical outcome and patient satisfaction. We described the origins and development of evidence-based medicine, narrative medicine and shared decision-making, and analyzed the existing problems in TCM clinical decision-making. Further, we put forward the model of shared decision-making between clinicians and patients under the guidance of narrative evidence-based medicine concepts and methods.

Management of upper gastrointestinal bleeding emergencies： evidence-based medicine and practical considerations

Acute upper gastrointestinal （GI） bleeding remains one of the most common encounters in emergency medicine. The increased use of non-steroid anti-inflammatory drugs by the general population and the increased prescription of anti-platelet agents and anti-coagulants after cardiovascular interventions and for prevention of cerebral vascular accidents may have aggravated the situation. Significant progress has been made in the past decade or so in the non-surgical management of acute upper GI bleeding emergencies. This article will review the current standard treatment of the most common upper GI bleeding emergencies in adults as supported by evidence- based medicine with practical considerations from the authors＇ own practice experience.

Clinical effects of antidiabetic drugs on psoriasis:The perspective of evidence-based medicine

Psoriasis and diabetes shared common underlying pathophysiological mechanisms.Emerging data suggested that antidiabetic medications may improve the psoriasis severity in patients with diabetes mellitus.Several hypoglycemic agents including thiazolidinediones,glucagon-like peptide-1 receptor agonists,dipeptidyl peptidase-4 inhibitors,and biguanides have been reported to make a remarkable reduction in the Psoriasis Area and Severity Index score from baseline.This antipsoriatic effect could be mediated not only by the glucoselowering action of these agents but also via inhibition of keratinocyte over proliferation,increase expression of differentiation markers,suppression the immune inflammatory pathway,and blocking the calcium channels and mitogen-activated protein kinase signaling pathways.On the other hand,there was no significant increase in adverse reactions associated with the treatment of pioglitazone or metformin.However,previous studies often had the relatively short duration of the trials,and did not have enough power to assess recurrence of psoriasis.Potential bias in the study and missing data could undermine the reliability of the results.Therefore,the appropriately randomized controlled studies with large sample sizes and long-term durations in various psoriasis patients are warranted for further support.

Medical futility in the era of evidence-based medicine

One definition of futility is any treatment that merely preserves permanent unconsciousness or fails to end total dependence of a patient on intensive medical care However, no agreement has ever been reached on what the exact defmition of futility is, as it is not only based on temporary values but also evolves into different subtypes, making it harder to define. The difficulty in dealing with futility problem is how doctors evaluate the futile situation, which is further complicated by lack of standards for specific diseases and experience-based prognosis, leading to subjectivity in evaluation for futility.

Developing evidence-based medicine in Persian medicine: obstacles, challenges, and solutions andsolutions

Introduction:Considering the importance of evidence-based medicine(EBM)and the emphasis of Persian medicine(PM)experts on its use,this study was designed;to investigate the practice of PM specialists,the obstacles,challenges,and solutions of developing and using EBM in PM were also the aims of the present study.Method:In the present study,98 PM specialists,who work in Iran completed the electronic Persian version of the evidence-based medicine.The effective factors in the practice of specialists were assessed by Spearman correlation and Mann-Whitney U tests.Results:The mean±standard deviation of age,graduation time,and clinical experience were 44.52±6.45,3.26±2.28,and 6.76±5.27 years,respectively.Evaluating the data showed,that 52 participants(53.1%)had not passed any EBM training courses.Social media,general and medical databases,textbooks,colleagues,and journal articles were used frequently in clinical practices,but the specific EBM-specific resources were neglected.Conclusions:More attention must be paid to produce scientific evidence,improving the infrastructures and health policies,and empowering PM specialists to apply EBM in their clinical practices.

The mistakes are often serious. Illustrating clinical examples are given as to how things can go wrong under the pressure baring on clinicians by the factors given.

Advances in COVID-19 management strategies with evolution of evidence-based medicine in India & associated ethical issues

The COVID-19 pandemic has been very challenging for the human race.This review aims to discuss the shaping of modern evidence-based medicine in India and address the emerging ethical issues.This review talks about testing strategies,management strategies,supportive and preventive strategies employed,and analysis of the evolving guidelines in relation to evidence-based medicine.The ethical issues addressed in this review are long-term side effects of vaccines,ethical issues related to Electronic Health Record,telemedicine,discharge policy,and prescription of unavailable/costly drugs.There appear to be many unidentified variables in decision-making and as a result,making guidelines based on low certainty evidence is a challenging task.Though there may be dissimilitude in various available evidence,one thing is quite clear that evidence-based medicine is the leading force in developing and formulating better health care practices.

Empirical study on the evidence-based medicine in court of China

Evidence-based medicine(EBM)is recognized as one of the highest-quality scientific approaches in the medical community around the globe.It calls for doctors to use the best available scientific evidence in clinical decision-making.This paper used an empirical study on 44 EBM related judicial cases in China,the result shows the EBM is commonly used as a supplement to the expert opinion in actual judicial review,it is deemed to illuminate the causation in the case fact rather than as the standards of care,which has the similar characteristics as"documentary evidence",and over the years the Chinese judicial practice formed a"three-stage"judicial review rule on EBM:(1)the first stage is whether the evidence itself can meet the standards of EBM;(2)the second stage is when determining the evidence presented by parties is sufficient to meet the legal standards of EBM,and whether it can be applied in a court case would depend upon comprehensive consideration of adaptability and maturity of EBM;(3)the third stage is whether to treat EBM as the only basis in causation analysis.

循证医学(Evidence-based Medicine)——临床研究与实践的新时代

80年代以来的大规模、随机、双盲、多中心、安慰剂对照临床试验证明,以经验和推论,如以一些临床化验指标为依据的传统临床试验不能反映病人的长期预后。为了对新药和已上市药物作出恰当的评价,应当从所谓“众说纷坛”转向注重和评价病人预后,包括总死亡率、重要心脑血管事件、生活质量、卫生经济学等的“循证医学”。反过来,“循证医学”和临床治疗指南的发展将对新药的研究与开发、医生的临床实践、药物经济学、医疗保健服务决策等带来积极和正面的影响。

Calling into Question the Efficacy of Evidence-Based Medicine: Is It Always the Best Approach? Is That Really the Placebo Effect?

The techniques of evidence-based medicine (EBM) are being frequently used recently. The generally accepted theory is that if a medicine is not absorbed by the body, it will have no effect. However, the author has noticed that even when substances, including medicines, are not absorbed by the body, they can have a marked effect. In some cases, just bringing the substance close to the body can have an effect;in such cases, the efficacy of EBM for estimating the therapeutic value of medicines may be debatable. Therefore, a more accurate evaluation method should be devised. The author proposes that another group be introduced into trials. This group would include subjects who were exposed to but did not have an opportunity to absorb the medicine being tested.

Evidence-Based Medicine Research on Prescriptions in Synopsis of the Golden Chamber in the Treatment of Pelvic Inflammatory Disease

Purpose: Based on the National Natural Science Foundation of China, we collect and sort out the literature published in approximately the last 30 years, which use prescriptions in Synopsis of the Golden Chamber to treat pelvic inflammatory disease (PID). This study provides theoretical basis for the treatment of PID;we recommend this achievement to colleagues. Method: Firstly, we searched and collected the literatures from last three decades in CNKI, Wanfang and VIP databases, which are about classical prescriptions treating endometriosis. Then, by screening all the literatures, we obtained the clinical research literatures and individual case reports. Finally, we went through the internal quality of the two categories of literatures to get the dominant prescriptions. Using a retrospective study of evidence-based medicine research, we comprehensively collect literature, standardize the disease spectrum, classify the evidence, and then evaluate the internal quality. Results: We refine 4 prescriptions which commonly are used in the treatment of PID;in other words, they are also the clinical symptoms of PID: Gui Zhi Fu Ling Wan symptom, which manifests blood stasis and cold-damp stagnancy;Dang Gui Shao Yao San symptom, which manifests disharmony of liver and spleen, qi-blood stasis and damp obstruction;Da Huang Mu Dan Tang symptom, which manifests the gathering toxic heat and qi-blood stasis;Yi Yi Fu Zi Bai Jiang San symptom, which manifests the internal toxic heat and qi-blood injury. Conclusion: This study is gospel for the patients with recurrent episodes of PID who can’t often use antibiotics. At the same time, it is also a green therapeutics which Chinese ancients dedicated to human medicine.

Research in spinal surgery: Evaluation and practice of evidence-based medicine

Evidence-based medicine(EBM) is a common concept among medical practitioners, yet unique challenges arise when EBM is applied to spinal surgery. Due to the relative rarity of certain spinal disorders, and a lack of management equipoise, randomized controlled trials may be difficult to execute. Despite this, responsibility rests with spinal surgeons to design high quality studies in order to justify certain treatment modalities. The authors therefore review the tenets of implementing evidencebased research, through the lens of spinal disorders. The process of EBM begins with asking the correct question.An appropriate study is then designed based on the research question. Understanding study designs allows the spinal surgeon to assess the level of evidence provided.Validated outcome measurements allow clinicians to communicate the success of treatment strategies, and will increase the quality of a given study design. Importantly,one must recognize that the randomized controlled trial is not always the optimal study design for a given research question. Rather, prospective observational cohort studies may be more appropriate in certain circumstances, and would provide superior generalizability. Despite the challenges involved with EBM, it is the future of medicine. These issues surrounding EBM are important for spinal surgeons, as well as health policy makers and editorial boards, to have familiarity.

EVIDENCE-BASED MEDICINE AND THE CLINICAL STUDY ON ACUPUNCTURE AND MOXIBUSTION

In this article, the authors hold that the evidence based medicine(EBM) is a new medical action produced at the historic moment in clinical practice, which is promoting development of the medicine and even the whole life science in a fully new train of thought and method. Further the briefly introduced contents are the effect of EBM, the difficulty of utilizing in the acupuncture clinical practice and how to resolve them. It is highly recommended that the doctors of the acupuncture science field should study EBM and its effect and difficulties in practice as earlier as possible, insistently assimilate new knowledge and keep abreast of the times’ progress to facilitate the further development of acupunctology.
