Near-Infrared Fluorescence Imaging Contrast Agents for Clinical Research: Limitations and Alternatives

Introduction: Near-infrared fluorescence imaging is a technique that will establish itself in the short term at the international level because it is recognized for its potential to improve the performance of surgical interventions, its moderate investment and operating costs and its portability. Although the technology is now mature, there is currently the problem of the availability of contrast agents to be injected IV. The aim of this methodology article is to propose an alternative solution to the need for contrast agents for clinical research, particularly in oncology. Methodology: They consist of coupling a fluorescent marker in the form of an NHS derivative, such as IR DYE manufactured in compliance with GMP, with therapeutic monoclonal antibodies having marketing authorization for molecular imaging. For a given antibody, the marking procedure must be the subject of a validation file on the final preparation filtered on a sterilizing membrane at 0.22 μm. Once the procedure has been validated, it would be unnecessary to repeat the tests before each clinical research examination. A check of the marking by thin-layer chromatography (TLC) and place it in a sample bank at +4˚C for 1 month of each injected formulation would be sufficient for additional tests if necessary. Conclusion: Molecular near-infrared fluorescence imaging is experiencing development, the process of which could be accelerated by greater availability of clinical contrast agents. Alternative solutions are therefore necessary to promote clinical research in this area. These methods must be shared to make it easier for researchers.

Guidelines on clinical research evaluation of artificial intelligence in ophthalmology(2023)

With the upsurge of artificial intelligence(AI)technology in the medical field,its application in ophthalmology has become a cutting-edge research field.Notably,machine learning techniques have shown remarkable achievements in diagnosing,intervening,and predicting ophthalmic diseases.To meet the requirements of clinical research and fit the actual progress of clinical diagnosis and treatment of ophthalmic AI,the Ophthalmic Imaging and Intelligent Medicine Branch and the Intelligent Medicine Committee of Chinese Medicine Education Association organized experts to integrate recent evaluation reports of clinical AI research at home and abroad and formed a guideline on clinical research evaluation of AI in ophthalmology after several rounds of discussion and modification.The main content includes the background and method of developing this guideline,an introduction to international guidelines on the clinical research evaluation of AI,and the evaluation methods of clinical ophthalmic AI models.This guideline introduces general evaluation methods of clinical ophthalmic AI research,evaluation methods of clinical ophthalmic AI models,and commonly-used indices and formulae for clinical ophthalmic AI model evaluation in detail,and amply elaborates the evaluation methods of clinical ophthalmic AI trials.This guideline aims to provide guidance and norms for clinical researchers of ophthalmic AI,promote the development of regularization and standardization,and further improve the overall level of clinical ophthalmic AI research evaluations.

Clinical research progress of traumatic brain injury related markers

Traumatic brain injury is a brain injury caused by biomechanics effects on brain tissue,In addition to primary brain injury,secondary brain injury caused by local brain injury,edema and high intracranial pressure on surrounding brain tissue further aggravates the disease.The improvement of modern medical equipment and medical technology can provide early intervention treatment for patients.However,due to the particularity of the disease and the complexity of pathological and physiological reactions,irreversible damage often occurs in the central nervous system,with high disability rate and mortality.In recent years,it has been found that the related biological markers in the process of TBI are related to brain tissue injury and neurological function,and have important clinical application value in judging the severity of brain injury and prognosis evaluation,which has been widely studied.This paper intends to summarize the clinical research progress of TBI-related prognostic markers.

Patient-centric periodontal research:A pioneering application of patient-reported outcome measures

Conventional dentistry or periodontal research often ignores the human component in favor of clinical outcomes and biological causes.Clinical research is driven by the statistical significance of outcome parameters rather than the satisfaction level of the patient.In this context,patient-centric periodontal research(PCPR)is an approach that considers the patient´s feedback concerning their functional status,experience,clinical outcomes,and accessibility to their treatments.It is argued that data self-reported by the patient might have low reliability owing to the confounding effect of their personal belief,cultural background,and social and economic factors.However,literature has shown that the incorporation of“patient-centric outcome”components considerably enhances the validity and applicability of research findings.Variations in the results of different studies might be due to the use of different and non-standardized assessment tools.To overcome this problem,this editorial enlists various reliable tools available in the literature.In conclusion,we advocate that the focus of researchers should shift from mere periodontal research to PCPR so that the results can be effectively applied in clinical settings and the therapeutic strategy can also change from mere periodontal therapy to patient-centric periodontal therapy.

The most important questions in cancer research and clinical oncology Question 2-5.Obesity-related cancers:more questions than answers

Obesity is recognized as the second highest risk factor for cancer. The pathogenic mechanisms underlying tobaccorelated cancers are well characterized and efective programs have led to a decline in smoking and related cancers, but there is a global epidemic of obesity without a clear understanding of how obesity causes cancer. Obesity is heterogeneous, and approximately 25% of obese individuals remain healthy(metabolically healthy obese, MHO), so which fat deposition(subcutaneous versus visceral, adipose versus ectopic) is "malignant"? What is the mechanism of carcinogenesis? Is it by metabolic dysregulation or chronic inflammation? Through which chemokines/genes/signaling pathways does adipose tissue influence carcinogenesis? Can selective inhibition of these pathways uncouple obesity from cancers? Do all obesity related cancers(ORCs) share a molecular signature? Are there common(overlapping) genetic loci that make individuals susceptible to obesity, metabolic syndrome, and cancers? Can we identify precursor lesions of ORCs and will early intervention of high risk individuals alter the natural history? It appears unlikely that the obesity epidemic will be controlled anytime soon; answers to these questions will help to reduce the adverse efect of obesity on human condition.

Acupuncture-a national heritage of China to the world:international clinical research advances from the past decade

Acupuncture originated in China and is an important component of traditional Chinese medicine.The elucidation of its anesthetic mechanisms,the medical needs of Western societies,as well as the proven therapeutic effects of this technique have made it the most widely used medical practice in the world.The concept of evidence-based medicine has been introduced in acupuncture research for technical improvement and the production of high-quality clinical evidence.Upon reviewing the acupuncture clinical research over the past 10years,we found the gradually increasing range of diseases that it benefits,from pain management to neoplasms and genitourinary,digestive,and mental disorders.Acupuncture is included in a number of international guidelines for clinical practice.However,high-quality clinical evidence to support the efficacy and effectiveness of acupuncture is lacking as a result of multiple exceptional clinical trials conducted by Western researchers that have yielded antagonistic results.Future clinical research should focus on exploring objective evaluation methods for studying the therapeutic effects of acupuncture.

Progress in clinical research on the integration of Chinese and Western medicines for treating primary liver cancer

Primary liver cancer(PLC) is one of the most common malignant tumors in China. PLC is characterized by insidious onset, rapid progress, poor quality of life, and short survival time. Notably, current treatment strategies remain unsatisfactory. Traditional Chinese medicines(TCM) have been used to treat a variety of diseases, including liver diseases, for more than 2000 years. In this study, we performed a review of the use frequency and clinical efficacy of TCM in treating PLC. Relevant literature from January 1, 2009, to January 1, 2021 was retrieved from network databases of China National Knowledge Infrastructure(CNKI), Chongqing VIP, Wanfang, PubMed, and SinoMed. The most frequently used TCM and their efficacy in PLC treatment were summarized. Based on the inclusion and exclusion criteria, 33 articles were selected. Overall, the efficacy of the combination of TCM and Western medicines in the treatment of PLC was higher than that in the control groups(i.e. treatment with Western medicines alone)(65.11% vs.44.31%, P <.05). Among the 33 selected articles, 11 were investigated for TCM preparation(marketed drugs) and 22 for TCM formulas. In total, 102 types of TCM(single herbs) were used to treat PLC. The top five most frequently used TCM were Poria(14.71%), Astragali radix(13.73%), Atractylodis Macrocephalae Rhizoma(12.75%), Bupleuri radix(12.75%), and Glycyrrhizae radix et Rhizoma(11.76%). Of the 102 types of TCM, tonics were the most frequently used categories, followed by heat-clearing medicines, blood-invigorating medicines, and stasis-resolving medicines. Of 207 papers, 174(84.06%) could not be subjected to statistical analysis due to research quality. Further high-quality research on herb sources, formula components and dosage, toxicology, and ethics of TCM is necessary. In conclusion, TCM play a promising role in the treatment and management of PLC, although further investigations are warranted.

Russian clinical research policy does not guarantee results availability

AIM： To investigate results availability from clinical studies enrolling Russian subjects and Russian clinical research policy.METHODS： We analyzed Russian legislation and ethi-cal regulations about drug and devices approval, clini-cal research registration and the results availability. In August 2012, we searched International Clinical Trials Registry Platform and clinicaltrials.gov to fnd all regis-tered studies that had an investigational site in the ter-ritory of the Russian Federation. To fnd publication sta-tus, we searched the PubMed and Scirus bibliographical databases with trial registration number to fnd journal publications of the registered studies.RESULTS： We identifed 2062 registered research pro-tocols comprising 2017 international and 45 protocols sponsored by the Russian funding agencies. The num-ber of the studies enrolling Russian subjects increased dramatically from three studies in 2002 to 252 studies in 2012. Most studies （92%） were funded exclusively by industry, were interventions （94.6%）, examined drugs （87%） and enrolled exclusively adults （86%） of both genders （89%）. Only 383 （19%） of multinational stud-ies and two （4.4%） of exclusively Russian studies werepublished. Posting of patient outcomes was available for 16% of the trials that recruited trial participants in the Russian territory including one study funded exclu-sively by Russian sponsors. Investigators terminated 99 studies of 38111 participants and did not provide the results in clinicaltrials.gov or in published manuscripts. Federal laws require clinical study registration and con-fict of interest disclosure. However, routine monitoring of compliance to clinical research policy is not available.CONCLUSION： Russian legislation does not guarantee the availability of clinical research results. Russian leg-islation should mandate transparent evidence- based market approval of the drugs and devices.
