Medical and social domains of ageing research in Singapore (2008-2018): a scoping review

INTRODUCTION@#This scoping review examined the number, types and characteristics of journal publications on ageing in Singapore from 2008 to 2018 to determine how ageing research in medical and social domains in Singapore has transformed over time.@*METHODS@#Using relevant search terms, articles were extracted from multiple databases and then screened and reviewed for eligibility and inclusion by independent reviewers. Data such as article title, authors, year of publication, name of journal, type of journal, study design and the kind of data used were charted from the included articles for evidence synthesis.@*RESULTS@#Since 2008, there has been a steady increase in the number of publications on ageing in medical and social domains in Singapore. In the medical domain, publications on Ophthalmology (22%) made up the largest proportion of the existing medical literature on ageing in Singapore, followed by Physical Functioning (17%), which involved physiological measurements of physical well-being, and Geriatrics (16%). Non-medical publications comprised 38% of all the included publications, with publications on the social aspects of ageing (43%) forming the largest group in this cluster, followed by publications on Prevention (19%) and Healthcare services (18%). The study design was mostly observational (82%), with only 3% of interventional studies.@*CONCLUSION@#While ageing research had expanded in Singapore in the last decade, it was predominantly discipline specific and observational in design. As ageing issues are complex, with biology intersecting with psychology and sociology, we call for greater interdisciplinary collaboration, the conduct of more interventional studies, as well as more research in understudied and emerging areas.

Myelin oligodendrocyte glycoprotein antibody-associated optic neuritis: an update / Neurite óptica associada com anticorpo contra a glicoproteína oligondendrócita da mielina: uma breve atualização

ABSTRACT Myelin oligodendrocyte glycoprotein-immunoglobulin G (IgG)-associated optic neuritis has been established as a new entity of immune-mediated optic neuropathy. Patients usually present with recurrent optic neuritis, often bilaterally with initially severe vision loss and optic disc edema. However, in contrast to aquaporin 4-IgG-seropositive neuromyelitis optica spectrum disorder, visual recovery tends to be more favorable, with good response to steroid treatment. Another important differential diagnosis of myelin oligodendrocyte glycoprotein-IgG--associated optic neuritis is multiple sclerosis. Close monitoring for signs of relapse and long-term immunosuppression may be considered to maintain optimal visual function. The diagnosis can be made on the basis of the presence of a specific, usually serological, antibody against myelin oligodendrocyte glycoprotein (IgG; cell-based assay), and a demyelinating event (optic neuritis, myelitis, brainstem syndrome, or cortical lesions with seizures). The clinical spectrum of this newly recognized inflammatory demyelinating disease is expanding rapidly. We briefly review the epidemiological characteristics, clinical manifestations, diagnostic considerations, and treatment options of myelin oligodendrocyte glycoprotein-IgG-associated optic neuritis.

RESUMO A neurite óptica associada à glicoproteína de oligodendrócito de mielina-IgG foi estabelecida como uma nova entidade de neuropatia óptica imunomediada. Tipicamente os pacientes apresentam neurite óptica recorrente, muitas vezes bilateral, com perda de visão frequentemente severa e alta prevalência de edema do disco óptico na fase aguda. No entanto, em contraste com neuromyelitis optica spectrum disorder associada com presença de anticorpo contra aquaporina 4, a recuperação visual tende a ser mais favorável e responde bem ao tratamento com corticoide em altas doses. A esclerose múltipla representa outro importante diagnóstico diferencial de glicoproteína de oligodendrócito de mielina-IgG. O diagnóstico pode ser feito com base na presença de um anticorpo específico, geralmente sorológico contra glicoproteína de oligodendrócito de mielina (IgG, ensaio baseado em células), e presença de evento desmielinizante (neurite óptica, mielite, síndrome do tronco cerebral, lesões corticais com convulsões). O espectro clínico desta doença desmielinizante inflamatória recém-reconhecida está se expandindo rapidamente. Faremos uma breve revisão das características epidemiológicas, manifestações clínicas, considerações diagnósticas e opções de tratamento da neurite óptica associada à glicoproteína de oligodendrócito de mielina-IgG.

Estudios de corte transversal: un diseño de investigación a considerar en ciencias morfológicas / Cross section studies: a research design to consider in morphological sciences

Los estudios de corte transversal (ECT) inician en la década de los 40 en países Europeos. Los ECT corresponden a investigaciones de tipo observacional que permiten estudiar prevalencia de enfermedad, determinar asociación entre variables y el desarrollo de un efecto de interés, conocer propiedades de una prueba diagnóstica, y censar poblaciones; describiendo las características de una población en un momento y lugar determinado. Esto implica, que no se requieren periodos de seguimiento, que no son prospectivos ni retrospectivos; características que permiten que sean más baratos y fáciles de realizar en relación a los estudios longitudinales. Por otro lado, al ser de carácter descriptivo sirven como insumo y evidencia preliminar para estudios de mayor complejidad metodológica, como estudios de cohortes. Sin embargo, tienen limitantes y sesgos que deben ser considerados por los investigadores. El objetivo de este manuscrito fue generar un documento de estudio para revisar características esenciales, fortalezas y debilidades; discutir cuestiones metodológicas de los ECT en ciencias de la salud; y proporcionar algunos ejemplos obtenidos de la literatura, para mejor comprensión del diseño.

SUMMARY: Cross-sectional studies (CSS) began European countries in the 1940s in. The CSSs correspond to observational-type investigations that allow studying the prevalence of disease, determining the association between variables and the development of an effect of interest, discovering the properties of a diagnostic test, and censusing populations, describing the characteristics of a population at a given time and place. This implies that follow-up periods are not required, and that they are neither prospective nor retrospective. These characteristics allow them to be cheaper and easier to perform in relation to longitudinal studies. On the other hand, being descriptive in nature, they serve as input and preliminary evidence for studies of greater methodological complexity, such as cohort studies. However, they have limitations and biases that must be considered by researchers. The aim of this manuscript was to generate a study document to review essential characteristics, strengths and weaknesses; discuss methodological issues of ECT in health sciences; and provide some examples obtained from the literature, for a better understanding of the design.

Discussion and Concern on Animal Study for Orthopaedic Implantable Devices / 中国医疗器械杂志

In recent years, new orthopaedic implantable devices continue to emerge, which require higher requirements for technical evaluation. Animal study is an important part of the research and development process for the new orthopedic implantable devices, which provides relevant evidence for product design and stereotyping. By introducing the purpose of animal study, and the application of 3R principle (replacement, reduction, refinement) in this field, we summarize the concern on the animal study, in order to provide reference for the development and research of new orthopedic implantable devices and biomaterials. At the same time, the application of evidence-based research methods such as systematic review in the field is introduced, which provides new tools and approaches for the technical review and regulatory science.

Re-evaluation of systematic reviews of acupuncture and moxibustion for childhood autism / 中国针灸

OBJECTIVE@#To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment.@*METHODS@#The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence.@*RESULTS@#A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias.@*CONCLUSION@#Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

Improving acupuncture research: progress, guidance, and future directions / 中国针灸

This paper makes an interpretation of the collection Acupuncture: how to improve the evidence base published by BMJ & BMJ Open. Studies show that the quality of randomized controlled trial (RCT) of acupuncture is low, and multivariable Meta-regression analysis fails to confirm most factors commonly believed to influence the effect of acupuncture. The methodological challenges in design and conduct of RCT in acupuncture were analyzed, and a consensus on how to design high-quality acupuncture RCT was developed. The number of acupuncture systematic reviews was huge but the evidence was underused in clinical practice and health policy, and a large number of western clinical practice guidelines recommended acupuncture therapy, but the usefulness of recommendations needed to be improved. In view of the problems in clinical research on acupuncture mentioned in this collection, combined with the analysis of the purpose of clinical research on acupuncture, perspectives, study types, as well as the relationship between evidence and clinical decision-making, a five-stage study paradigm of clinical research on acupuncture is proposed.

Acupoint compatibility effect: increasing "effect value" and expanding "effect domain" / 中国针灸

By summarizing and exploring the theoretic connotation, key of functions and effect mechanism of acupoint compatibility, the effect of acupoint compatibility is concluded as the increase of "effect value" and the expansion of "effect domain". The increase of "effect value" is the concrete embodiment by the value of medical assessment scale, the value of objective index detection in clinical trial and the value of index detection in experiment research. The expansion of "effect domain" is the increase of effect target and the extension of effect scope. The paper interprets the scientific connotation of acupoint compatibility therapy from a new perspective, and emphasizes the innovative approaches to research while bringing forth new ideas on the research method. It is anticipated that a novel breakthrough can be achieved in the study of acupoint compatibility and the improvement of acupuncture-moxibustion efficacy.

Basic research of meridian-tendon based on fascia: review and prospects / 中国针灸

Meridian-tendon is a central concept in meridian theory of TCM, and its basic research has been increasingly emphasized. While there is no unified understanding of the essence of meridian-tendon, the concept that function of fascia could partially reflect the functions of meridian-tendons has reached consensus in the academic community. This article suggests that under the guidance of meridian-tendon theory, based on previous research foundation of fascia, focusing on adopting fascia research methods, the mechanisms of tender point hyperalgesia and abnormal proliferation related to meridian lesions should be adopted to explain yitong weishu (taking the worst painful sites of muscle spasm as the points), and the mechanisms of meridian intervention efficacy should be adopted to explain yizhi weishu (feelings from patients and acupuncture operators). Furthermore, this article provides an analysis of the future trends in basic research of meridian tendons.

Blinding assessment in clinical trials of traditional Chinese medicine: Exploratory principles and protocol / 中西医结合学报

As one of the key components of clinical trials, blinding, if successfully implemented, can help to mitigate the risks of implementation bias and measurement bias, consequently improving the validity and reliability of the trial results. However, successful blinding in clinical trials of traditional Chinese medicine (TCM) is hard to achieve, and the evaluation of blinding success through blinding assessment lacks established guidelines. Taking into account the challenges associated with blinding in the TCM field, here we present a framework for assessing blinding. Further, this study proposes a blinding assessment protocol for TCM clinical trials, building upon the framework and the existing methods. An assessment report checklist and an approach for evaluating the assessment results are presented based on the proposed protocol. It is anticipated that these improvements to blinding assessment will generate greater awareness among researchers, facilitate the standardization of blinding, and augment the blinding effectiveness. The use of this blinding assessment may further advance the quality and precision of TCM clinical trials and improve the accuracy of the trial results. The blinding assessment protocol will undergo continued optimization and refinement, drawing upon expert consensus and experience derived from clinical trials.

Research progress of Mendelian randomization analysis in intensive care medicine / 中华危重病急救医学

The condition of critically ill patients changes rapidly, involving pathological changes in multiple systems and organs throughout the body. Exploring the causal relationship of mechanisms can further reveal etiology, treatment, and prognosis of diseases. However, traditional prospective studies in the field of critical care are still subject to numerous limitations. As an emerging research method, Mendelian randomization (MR) analysis uses genetic variation to provide causal evidence for instrumental variables, which is expected to provide clues in critical diseases. This article systematically describes the research progresson the application of MR analysis in critical care medicine from four aspects: the principle of MR analysis, the difference between MR analysis and randomized controlled trial (RCT), the use of MR analysis in the field of critical illness, and the possible methods of application, aiming to provide possible directions for the research in this field.

Assessing the impact of educational methods on influenza vaccine uptake and patient knowledge and attitudes: a randomised controlled trial

INTRODUCTION@#Although influenza vaccination reduces rates of pneumonia, hospitalisation and mortality, influenza vaccination uptake remains low in older patients. The primary aim was to compare individualised counselling with educational pamphlets alone in improving influenza vaccination uptake. The secondary aims were to evaluate knowledge and attitudes towards influenza vaccination and factors influencing uptake.@*METHODS@#A randomised controlled study was conducted in two government polyclinics with 160 participants per arm. Patients aged 65 years and above attending for doctor consultation were recruited. All participants received an educational pamphlet on influenza vaccination. The intervention group received additional face-to-face counselling. Participants filled a pre- and postintervention questionnaire assessing knowledge of influenza and attitudes towards the vaccine. Follow-up calls and verification of electronic records was done at three months to determine actual vaccine uptake.@*RESULTS@#At three months, 16 (10%) patients in the intervention group and 20 (12.5%) patients in the control group had completed influenza vaccination (P = 0.48). Factors positively associated with vaccine uptake were willingness to receive vaccination immediately after intervention (adjusted odds ratio [OR] 12.15, 95% confidence interval [CI] 4.42-33.38), and male gender (adjusted OR 2.96, 95% CI 1.23-7.12). Individualised counselling was more effective in improving knowledge (P < 0.01). Overall knowledge scores did not influence actual vaccine uptake rates. (adjusted OR 1.10 [0.90-1.3]).@*CONCLUSION@#Both arms of patient education increased uptake of influenza vaccination. Individualised counselling was not superior to pamphlets alone in improving uptake. Performing vaccination at the initial point of contact improves actual uptake rates.

Species identification of Ligustrum lucidum / 中国中药杂志

Ligustrum lucidum is a woody perennial plant of genus Ligustrum in family Oleaceae. Its dried fruit has high medicinal value. In this study, the authors evaluated the variability and species identification efficiency of three specific DAN barcodes(rbcL-accD, ycf1a, ycf1b) and four general DAN barcodes(matK, rbcL, trnH-psbA, ITS2) for a rapid and accurate molecular identification of Ligustrum species. The results revealed that matK, rbcL, trnH-psbA, ITS2 and ycf1a were inefficient for identifying the Ligustrum species, and a large number of insertions and deletions were observed in rbcL-accD sequence, which was thus unsuitable for development as specific barcode. The ycf1b-2 barcode had DNA barcoding gap and high success rate of PCR amplification and DNA sequencing, which was the most suitable DNA barcode for L. lucidum identification and achieved an accurate result. In addition, to optimize the DNA extraction experiment, the authors extracted and analyzed the DNA of the exocarp, mesocarp, endocarp and seed of L. lucidum fruit. It was found that seed was the most effective part for DNA extraction, where DNAs of high concentration and quality were obtained, meeting the needs of species identification. In this study, the experimental method for DNA extraction of L. lucidum was optimized, and the seed was determined as the optimal part for DNA extraction and ycf1b-2 was the specific DNA barcode for L. lucidum identification. This study laid a foundation for the market regulation of L. lucidum.

Overview of systematic reviews of Chinese herbal injections for sepsis / 中国中药杂志

In this study, an overview of systematic reviews/Meta-analysis(SR/MA) of Chinese herbal injections for sepsis was performed to provide references for clinical practice and promote the quality improvement of clinical evidence. Eight Chinese and English databases such as CNKI, Medline, and EMbase were electronically searched for SR/MA of Chinese herbal injections for sepsis from database inception to June 2022. AMSTAR 2, PRISMA 2020, and GRADE system, combined with Recommendations for Clinical Evidence Grading on Traditional Chinese Medicine Based on Evidence Body, were applied to evaluate the methodological quality, reporting quality, and evidence quality of the included articles. Twenty-seven articles of SR/MA were included, containing four Chinese herbal injections(Xuebijing Injection, Shenfu Injection, Shenmai Injection, and Shengmai Injection). AMSTAR 2 checklist showed that the methodological quality of the SR/MA ranged from moderate to very low. Item 2(prior study design) was the critical item with poor scores, and the non-critical items with poor scores were items 3(explain the selection of the study designs), items 10(report on the sources of funding), and items 16(conflicts of interest stated). In terms of PRISMA 2020, items in eight topics with complete reporting of missing>50%, including search strategy, certainty assessment, results of syntheses, certainty of evidence, registration and protocol, support, competing interests, availability of data, code and other materials. The included SR/MA involved 30 outcome indicators. Evidence quality of mortality, APACHE Ⅱ, and safety, the top three outcome indicators, was evaluated, and all of them were graded as the medium level. The lack of random allocation sequence, allocation concealment mechanism, blinding, and trial sample size was the main reason for the reduction of the evidence level. The available evidence shows that Chinese herbal injections can serve as an effective and safe adjunctive treatment for sepsis, which can reduce mortality, inhibit inflammation, improve coagulation function, and regulate immune function, tissue perfusion, and oxygenation in patients with sepsis. However, the quality of SR/MA was suboptimal, and more high-quality SR/MA is needed to provide evidence to support the efficacy and safety of Chinese herbal injections in the treatment of sepsis.

Investigation of medical humanistic practice ability of nurses and factors affecting their practices: a questionnaire-based analysis of 1196 cases in a general hospital in Hunan Province / 南方医科大学学报

OBJECTIVE@#To investigate humanistic practice ability of nurses in a general hospital in Hunan Province and analyze the factors affecting their practices to provide evidence for interventions to improve humanistic practice ability of the nurses.@*METHODS@#A total of 1196 nurses were surveyed using a self-designed questionnaire and a nurse humanistic practice ability assessment scale questionnaire for assessment of their abilities for humanistic care practice, psychological adjustment, interpersonal communication, self-management, ethics and legal practice. Univariate and multivariate analyses were performed for analysis of the factors affecting the practice abilities of the nurses.@*RESULTS@#The total score of humanistic practice ability of the 1196 nurses was 105.69±16.45 (the full score of the scale was 130), and the scores of humanistic care practice ability, psychological adjustment ability, interpersonal communication ability, self-management ability, ethics and legal practice ability were 40.95±6.46, 16.41±2.66, 16.41±2.66, 11.32±2.05 and 12.43±2.00, respectively. Univariate analysis and multiple linear regression analysis showed that gender (P=0.033), age (P < 0.001), department (P=0.015), working years (P < 0.001), professional title (P < 0.001), first academic degree (P < 0.001), highest academic degree (P < 0.001), family location (P=0.010), marital status (P=0.023), number of patients to care for (P=0.022), number of children (P=0.001), previous humanities related training (P < 0.001), training times (P < 0.001), and care received from family members (P < 0.001) and colleagues (P < 0.001) were all the factors affecting humanistic practice ability of the nurses. Among these factors, age, working in department of obstetrics and gynecology and emergency department, professional title, humanities training, and care from family and colleagues explained 20.7% of the variance.@*CONCLUSION@#The humanistic practice ability of nurses in this general hospital is above the average level, but their self-management ability needs to be improved. Intervention measures should be implemented to improve the nurses' humanistic practice ability including more attentions to the key groups and departments, strengthening the training of humanistic practice ability, and improving the promotion assessment system.

Chinese Medicine as Supporting Therapy for Psoriasis: Past, Present, and Future / 中国结合医学杂志

Psoriasis is a chronic skin disease and an important health concern. Western medicine and therapies are the main treatment strategies for psoriasis vulgaris (PV); however, the overall prognosis of patients with PV is still poor. Therefore, PV prevention is especially crucial. Chinese medicine (CM) has a long history of treating psoriasis, and it has unique wisdom in different cognitive angles and treatment modes from modern medicine. In this review, we first summarized the herbs and ancient CM formulas that have therapeutic effects on PV. Second, the research status and obstacles to the current development of CM in modern medicine were reviewed. Finally, the future of CM in the context of precision medicine and integrated medicine was discussed. After a detailed reading of the abundant literature, we believe that CM, through thousands of years of continuous development and clinical practice, has achieved high effectiveness and safety for PV treatment, despite its surrounding controversy. Moreover, precise analyses and systematic research methods have provided new approaches for the modernization of CM in the future. The treatment of PV with CM is worth popularizing, and we hope it can benefit more patients.
