El objetivo del trabajo fue describir relaciones entre los cuidados que reciben niños y niñas de 3 y 4 años, según el marco para el cuidado cariñoso y sensible (NC, por sus siglas en inglés), y sus niveles de DIT en Argentina, considerando región y quintiles de riqueza. Población y métodos. Estudio analítico observacional de corte transversal, a partir de las bases de datos de la Encuesta Nacional de Niñas, Niños y Adolescentes (MICS) Argentina 2019-2020. Se seleccionaron 11 indicadores de NC y se estimó el nivel de DIT utilizando el Índice de Desarrollo Infantil Temprano (ECDI) para un análisis estadístico descriptivo. Resultados. En 2638 niños y niñas de 3 y 4 años evaluados, el promedio de acceso a indicadores de cuidados fue del 79,1 %; el acceso fue alto en 7 indicadores (entre el 84,2 % y el 97,9 %) y medio en 4 (entre el 46,9 % y el 65,1 %); la mayor frecuencia fue contar con registro de nacimiento (97,9 %) y la menor, la cobertura de seguro de salud (46,9 %). El 87,9 % alcanzó niveles adecuados de ECDI. Los resultados registran diferencias según quintiles de riqueza y regiones. Conclusiones. Los resultados evidencian desigualdades de acceso a cuidados y en DIT adecuado de niños y niñas de 3 y 4 años de áreas urbanas de Argentina según la región donde viven y el nivel de riqueza de sus hogares.

Introduction. One of the main challenges for early childhood is to provide adequate care to reduce inequalities and promote an early childhood development (ECD). The objective of this study was to describe the relationship between the care provided to children aged 3 and 4 years according to the nurturing care (NC) framework and their ECD levels in Argentina, considering the region and wealth quintiles. Population and methods. This was an observational, cross-sectional analytical study based on data from the National Survey of Children and Adolescents (MICS) of Argentina 2019­2020. A total of 11 NC indicators were selected; the level of ECD was estimated using the Early Childhood Development Index (ECDI) for a descriptive, statistical analysis. Results. In 2638 children aged 3 and 4 years assessed, the average access to care indicators was 79.1%; access was high for 7 indicators (between 84.2% and 97.9%) and middle for 4 indicators (between 46.9% and 65.1%); the highest and lowest frequency corresponded to having a birth certificate (97.9%) and health insurance coverage (46.9%), respectively. Adequate ECDI levels were observed in 87.9%. Results show differences by wealth quintile and region. Conclusions. The results evidence inequalities in terms of access to care and an adequate ECD of children aged 3 and 4 years from urban areas of Argentina, depending on the region where they live and their household wealth level.

¿Ensayos clínicos de superioridad, equivalencia o no inferioridad? / ¿Clinical trials of superiority, non-inferiority or equivalence?

La eficacia de una nueva intervención se establece generalmente a través de ensayos clínicos (EC) con asignación aleatoria (AA). Sin embargo, entre otros tantos desafíos metodológicos, el especificar la hipótesis de un EC con AA, sigue siendo un problema complejo de resolver para los investigadores clínicos. En este manuscrito discutimos las características de tres variantes de los EC con AA: EC de superioridad (ECS), EC de no-inferioridad (ECNI), y EC de equivalencia (ECE). Estos tres tipos de EC tienen supuestos diferentes sobre los efectos de una intervención, por lo que plantear hipótesis y definir objetivos requiere conocer algunos supuestos subyacentes a estos EC, incluso hasta elementos relacionados con la estimación del tamaño de muestra para cada cual. El objetivo de este manuscrito fue describir las diferencias metodológicas entre ECS, ECNI y ECE.

Efficacy and effectivity of new interventions are generally established through randomized clinical trials (RCTs). However, among many other methodological challenges, specifying the hypothesis of a RCT remains complex problem for clinical researchers. In this manuscript we discuss the characteristics of three variants of RCTs: superiority RCT (SRCT), non-inferiority RCT (NIRCT), and equivalence RCT (ERCT). These three types of RCT have different assumptions about the effects of an intervention, so setting hypotheses and defining objectives requires knowing some assumptions underlying these RCTs, including elements related to the estimation of the sample size for each one. The aim of this manuscript was to describe methodological differences between SRCT, NIRCT and ERCT.

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.

Operational nursing managers' experiences of clinical supervision at a Johannesburg Hospital

Background: Clinical supervision is pivotal in supporting nurses in rendering quality, safe patient care. Therefore, it is essential to understand clinical supervision from operational nursing managers' context to define existing challenges and propose suitable recommendations. Objectives: This study aimed to explore and describe operational nursing managers' experiences of clinical supervision within the context of an academic hospital in Gauteng province and propose evidence-based practice recommendations to improve patient safety and the quality of clinical supervision. Method: An exploratory, sequential, mixed-method design was used and implemented over two phases to take advantage of the strengths of both the qualitative and quantitative research designs. Unstructured individual interviews were conducted to collect data in phase one, and an adapted Manchester Clinical Supervision Scale (MCSS) questionnaire was used to collect data in phase two. Results: Operational nursing managers work in stressful conditions and environments with a gross shortage of staff and tools of the trade while being expected to deliver high-quality and safe nursing care. Of the sampled respondents, 36% (n = 17) were dissatisfied with the supervision they received, while 64% (n = 30) were indifferent in the sense that they did not think it was adequate or inadequate. Conclusion: Clinical supervisors should be trained and supported in clinical supervision, with regular workshops on interpersonal relations. Contribution: A clearer understanding of clinical supervision within the hospital context and evidence-based practice recommendations to improve patient safety and the quality of clinical supervision.

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.

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.

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.

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.

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.
