Extraction of geraniol from palmarosa oil using hydrotropic solvents / Extracción de geraniol del aceite de palmarosa utilizando solventes hidrotrópicos

The extraction of geraniol from palmarosa oil using hydrotropic solvents was investigated. Palmarosa oil possesses an appealing rose aroma and properties like anti - inflammatory, antifungal, and antioxidant due to the presence of geraniol. The extraction of geraniol from palmarosa oil by using distillation methods like steam dis tillation and fractional distillation was a laborious process. So hydrotropes were tried for extraction. The geraniol yield and purity depend on parameters like concentration of hydrotrope, solvent volume ratio, and time period. Using the Box Benkhem Desig n (BBD), the extraction process was optimized. One of the major advantages of using hydrotropic solvents is that they were classified as green solvents, and recovery of solvents is also possible. To reduce the extraction time probe sonication is carried ou t. Different hydrotropic solvents with probe sonication are done on palmarosa oil by altering various process parameters to study the separation, yield, and purity.

Se investigó la extracción de geraniol del aceite de palmarosa utilizando solventes hidrotrópicos. El aceite de palmarosa posee un atractivo aroma a rosa y propiedades antiinflamatorias, antifúngicas y antioxidantes debido a la pr esencia de geraniol. La extracción de geraniol del aceite de palmarosa mediante métodos de destilación como la destilación por vapor y la destilación fraccionada ha sido un proceso laborioso. Por lo tanto, se probaron los hidrotropos para la extracción. El rendimiento y la pureza del geraniol dependen de parámetros como la concentración del hidrotropo, la relación de volumen del solvente y el período de tiempo. Se optimizó el proceso de extracción usando el diseño Box Benkhem (BBD). Una de las principales v entajas de usar solventes hidrotrópicos es que se clasifican como solventes verdes y también es posible recuperar los solventes. Para reducir el tiempo de extracción, se lleva a cabo una sonda de ultrasonido. Se realizan diferentes solventes hidrotropos co n sonda de ultrasonido en el aceite de palmarosa alterando varios parámetros del proceso para estudiar la separación, el rendimiento y la pureza.

Investigación cualitativa en el contexto de la Salud Pública: actualización de conceptos

Los enfoques cualitativos en la investigación han sido fundamentales en las ciencias sociales y son cruciales para el estudio de la salud y los servicios sanitarios. Con el progreso en medicina, mayor especialización, expectativas crecientes de los pacientes y la complejidad de los servicios de salud, los profesionales se enfrentan a un entorno laboral cada vez más complicado. Los métodos cualitativos, aunque distintos de las técnicas experimentales y cuantitativas de la investigación clínica y biomédica, son indispensables para la investigación en servicios de salud. Esto se debe a que permiten explorar aspectos no medibles cuantitativamente, como las creencias sobre la salud, y porque proporcionan una base -descriptiva necesaria para la investigación cuantitativa, especialmente en campos con escasa investigación previa.

Qualitative approaches in research have been fundamental in the social sciences and are crucial to the study of health and health services. With progress in medicine, greater specialization, increasing patient expectations and the complexity of health services, professionals face an increasingly complicated work environment. Qualitative methods, although different from the experimental and quantitative techniques of clinical and biomedical research, are essential for health services research. This is because they allow us to explore aspects that are not quantitatively measurable, such as beliefs about health, and because they provide a necessary descriptive basis for quantitative research, especially in fields with little previous research.

¿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.

Desafios avaliativos em cenário ribeirinho: pistas metodológicas para o acesso à rede de urgência e emergência / Evaluation challenges in a ribeirinho context: methodological clues in accessing the urgency and emergency network / Desafíos evaluativos en el escenario ribereño: pistas metodológicas para el acceso a la red de urgencia y emergencia

O acesso à saúde e às políticas públicas em áreas remotas é um desafio relevante aos sistemas públicos no Brasil, dada sua dimensão e diversidade territorial. Este artigo tem como proposta apresentar o modelo teórico-lógico elaborado para avaliar o acesso da população ribeirinha à rede de urgência e emergência (RUE) em cenário amazônico, com vistas a fortalecer o planejamento, o monitoramento e a avaliação em saúde voltados para populações específicas. O ponto de partida metodológico foi a revisão temática sobre o acesso à saúde e o contexto amazônico na sua inter-relação com a proposta da pesquisa, que foi problematizada em encontros com colaboradores. Em seguida, buscou-se compreender e analisar os componentes teórico e lógico do modelo e adaptá-los à tríade donabediana ­ estrutura, processo e resultado. O resultado configurou a construção do modelo propriamente dito, com centralidade nas características que representam a oferta dos serviços (sócio-organizacional) e que retratam principalmente o espaço (geográfico). Esses pontos de construção do modelo demonstram sua contribuição para subsidiar outros processos avaliativos e o impacto final na tomada de decisão para qualificar o acesso da população ribeirinha à saúde em momento de sofrimento agudo, auxiliando na superação das condições que segregam essas populações.

Access to health and public policies in remote areas is a major challenge for public systems in Brazil, given its dimension and territorial diversity. This article presents a theoretical-logical model designed to assess the ribeirinho population's access to the urgency and emergency network in the Amazon as to strengthen health planning, monitoring, and evaluation aimed at specific populations. Starting from a thematic review on access to health and the Amazon in its interrelation with the research proposal, which were problematized in meetings with collaborators, the research sought to understand and analyze the model's theoretical and logical components and adapt them to the Donabedian triad (structure, process and result). This resulted in the model itself, centered on service provision (socio-organizational) and the space (geographic). These points demonstrate its contribution to support other evaluation processes and the final impact on decision-making to qualify this population's access to health under acute suffering, helping to overcome current restrictive conditions.

Itinerários de cuidado à saúde de mulheres em situações de abortamento: aspectos metodológicos do estudo qualitativo da pesquisa Nascer no Brasil II / Itinerarios para el cuidado de la salud de mujeres en situación de abortamiento: aspectos metodológicos del estudio cualitativo de la encuesta Nacer en Brasil II / Health care itineraries for women in situations of abortion: methodological aspects of a qualitative study for Birth in Brazil II survey

Nas últimas décadas, produziu-se um robusto corpus de pesquisas sobre aborto no Brasil, com diferentes desenhos, objetos e metodologias. Contudo, pela diversidade de situações em que as mulheres brasileiras vivenciam o abortamento, pela complexidade do tema e por suas modulações em contextos políticos e socioculturais distintos, o assunto não cessa de desafiar a academia, o campo da saúde e dos direitos reprodutivos. Neste artigo, apresentamos aspectos metodológicos de um estudo qualitativo sobre itinerários de cuidado à saúde de mulheres em situações de abortamento, componente da pesquisa Nascer no Brasil II, que objetiva discutir efeitos das desigualdades de gênero, de raça/etnia, de classe social, geracionais, regionais e territoriais nesses percursos. Discutimos o desenvolvimento do desenho do estudo; a construção do arcabouço teórico e recortes analíticos específicos; a elaboração do instrumento de entrevista; os critérios de seleção das mulheres; as estratégias de abordagem e condução das entrevistas; a gestão do fluxo do campo e dos materiais produzidos; os procedimentos analíticos; e os problemas éticos. Para incluir uma diversidade de mulheres e aprofundar resultados do componente quantitativo do Nascer no Brasil II, serão realizadas 120 entrevistas narrativas. O contexto de criminalização do aborto impacta a produção de conhecimento sobre o tema, impondo desafios como conseguir acesso às mulheres, assegurar o anonimato e sua privacidade, além do sigilo das informações, gerar condições objetivas e subjetivas para que possam narrar em profundidade as suas experiências. Com este artigo, procuramos contribuir para o debate sobre esses desafios das pesquisas sobre aborto no Brasil.

En las últimas décadas, se produjo un robusto corpus de investigaciones sobre el aborto en Brasil, con diferentes diseños, objetos y metodologías. Sin embargo, debido a la diversidad de situaciones en las que las mujeres brasileñas vivencian el abortamiento, la complejidad del tema y sus modulaciones en diferentes contextos políticos y socioculturales, el tema continúa desafiando a la academia, el campo de la salud y los derechos reproductivos. En este artículo, presentamos aspectos metodológicos de un estudio cualitativo sobre los itinerarios de cuidados de la salud de mujeres en situación de abortamiento, componente de la encuesta Nacer en Brasil II, que tiene como objetivo discutir los efectos de las desigualdades de género, raza/etnia, clase social, generacionales, regionales y territoriales en esos recorridos. Discutimos el desarrollo del diseño del estudio, la construcción del marco teórico y los recortes analíticos específicos, la elaboración del instrumento de entrevista, los criterios de selección de las mujeres, las estrategias de abordaje y realización de las entrevistas, el manejo del flujo del campo y de los materiales producidos, los procedimientos analíticos y los problemas éticos. Para abarcar una diversidad de mujeres y profundizar los resultados del componente cuantitativo de Nacer en Brasil II, se realizarán 120 entrevistas narrativas. El contexto de criminalización del aborto impacta la producción de conocimiento sobre el tema, imponiendo desafíos, tales como conseguir acceso a las mujeres, asegurar su anonimato y privacidad y la confidencialidad de la información, generar condiciones objetivas y subjetivas para que puedan narrar en profundidad sus experiencias. Con este artículo buscamos contribuir al debate sobre estos desafíos de las investigaciones sobre el aborto en Brasil.

In recent decades, several academic studies on abortion have been produced in Brazil, with different designs, objectives, and methodologies. However, due to the diversity of situations in which Brazilian women experience abortion, the complexity of this topic, and its modulations in different political and sociocultural contexts, it still challenges academicians and the fields of health and reproductive rights. In this article, we present methodological aspects of a qualitative study on health care itineraries of women in situations of abortion, a component of the Birth in Brazil II survey, whose objective is to discuss the effects of gender; race/ethnicity; social class; generational, regional, and territorial inequalities on care itineraries. We discuss the study design development, the construction of the theoretical framework and specific analytical axes, the development of interview instrument, definition of participant selection criteria, strategies to contact participants and conduct the interviews, management of field work and materials produced, analytical procedures, and ethical issues. In total, 120 narrative interviews were conducted in order to include a diversity of women and obtain detailed results from the quantitative analysis under Birth in Brazil II survey. The context of criminalization of abortion has an impact on the production of knowledge on this subject, creating challenges such as difficult access to women, women's anonymity, privacy and data confidentiality, creation of objective and subjective conditions so that they can narrate their experiences in depth. With this article, we seek to contribute to the debate about these challenges in abortion research in Brazil.

Precarious work and methodological challenges to study hard-to-reach populations

ABSTRACT OBJECTIVE To describe the methodological challenges and strategies of a web survey on the working conditions and health among delivery workers. METHODS The study population consisted of Brazilian delivery workers operating in the national territory. Procedures include building solid and ongoing collaboration with worker representatives and conducting a four-month data collection from February to May 2022, sharing the link to the online questionnaire on social media such as social networks (Facebook, Instagram) and messaging apps (WhatsApp, Telegram). RESULTS The recruitment of 41 leaders or influencers of delivery workers increased the dissemination of the study, some of whom participated in the consensual validation of the questionnaire; the production of content for social media for the dissemination of the questionnaire link on social networks and applications, and the in-person dissemination of the study at the delivery workers' meeting points during the workday played a fundamental role, totaling around 132 hours in 45 shifts. The strategies adopted for data collection with a hybrid approach to dissemination made it possible to carry out the web survey. After four months of the web survey, 564 delivery workers, 543 men and 18 women, responded to the online questionnaire. CONCLUSION The web survey presented methodological strategies to overcome the challenge of reaching workers, including hybrid work, to increase the participation of workers, on whom epidemiological research is still scarce.

Methodological Evaluation of Advantages of Traditional Chinese Medicine Treatment of Sjögren's Syndrome / 中国实验方剂学杂志

Screening and evaluating the diseases responding specifically to traditional Chinese medicine （TCM） will help to highlight the advantages of TCM treatment， and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome （SS） is increasing year by year， while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants， which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM， Western medicine， and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis， and SS was selected as a disease responding specifically to TCM. Furthermore， the evaluation system was established for this disease， and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First， because TCM atomization is widely used in clinical practice and enriches TCM administration methods， this therapy is included after other non-drug therapies were taken as characteristic therapies. Second， the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third， the expression method should be accurate， standardized， and objective， highlight the natural advantages of TCM， and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

Preparation and in vitro dissolution behaviors evaluation of silymarin phospholipid complex / 药学实践杂志

Objective To prepare silymarin phospholipids complex（SM-PC） and investigate its physicochemical properties. Methods On the basis of single-factor tests, the drug-lipid ratio, drug concentration and reaction temperature were selected as the factors of the central composite design and response surface methodology in the preparation of SM-PC by solvent volatilization, and the best process was optimized with the compound rate as the index. And its in vitro dissolution was measured. Results The optimum preparation technology of SM-PC was as follows: acetone was used as compound solvent, the concentration of SM was 8.0 mg/ml, the mass ratio of SM to phospholipid was 1∶1.8, the reaction temperature was 56 ℃ and the recombination rate was（95.15±1.55）% with deviation of less than 3%. The in vitro dissolution test showed that the dissolution of SM-PC was close to 90% in 60 min.

Optimization of Decoction Technology and Establishment of Quality Standard for Moringa oleifera Leaf Standard Decoction / 中国实验方剂学杂志

ObjectiveBased on response surface methodology combined with principal component analysis（PCA）， the optimal decocting process of Moringa oleifera leaf standard decoction was optimized， and its multi-index quality evaluation system was established， in order to provide scientific basis for the quality control of this standard decoction. MethodResponse surface methodology and PCA were used to optimize the decoction process by taking the relative peak areas of 8 characteristic peaks and dry extract yield as indexes. Based on this， the quality of 15 batches of the standard decoction was evaluated by high performance liquid chromatography（HPLC） characteristic chromatogram， determination of major components（neochlorogenic acid， L-tryptophan， cryptochlorogenic acid， vicenin-2， isoquercetin， astragalin）， determination of active parts（total flavonoids， total organic acids， total polysaccharides， total α-amino acids， total sinapine）， dry extract yield， specific gravity and pH. ResultThe optimal decocting process was to soak M. oleifera leaves（100.00 g） for 30 min and decoct twice with the first decoction of 12 times the amount of water for 30 min and the second decoction of 10 times the amount of water for 20 min. Standard decoction containing 0.2 g·mL-1 of crude drug was defined by x¯±30%， the specific gravity was 0.722-1.340， pH was 3.86-7.16， dry extract yield was 23.1%-42.9%， and the alcohol-soluble extract content was 8.26%-15.34%. Calculated according to the dried products of the standard decoction， the contents of neochlorogenic acid， L-tryptophan， cryptochlorogenic acid， vicenin-2， isoquercetin and astragalin were 1.99-3.69， 1.20-2.22， 1.44-2.67， 0.53-0.99， 2.45-4.55， 1.22-2.26 mg·g-1， the relative transfer rates relative to the herbs were 34.37%-63.83%， 62.43%-115.94%， 64.65%-120.06%， 56.98%-105.82%， 37.46%-69.57%， 41.81%-77.64%， respectively. The contents of total flavonoids， total organic acids， total polysaccharides， total α-amino acids， total sinapine were 10.19-18.92， 11.82-21.96， 94.07-174.71， 42.69-79.27， 9.55-17.73 mg·g-1， the relative transfer rates for herbs were 25.72%-47.77%， 41.78%-77.59%， 64.90%-120.54%， 42.30%-78.57%， 34.99%-64.99%， respectively. ConclusionThe optimized decocting technology of M. oleifera leaf standard decoction is stable and feasible， and the established multi-indicator quality evaluation system can lay the foundation for the quality control of this standard decoction.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 5）： Retrieval and Synthesis of Key Information on Rational Drug Use / 中医杂志

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 4）： Evidence Retrieval and Evaluation / 中医杂志

The retrieval and evaluation of evidence is the basis for the development of clinical practice guidelines for Chinese patent medicine. As traditional Chinese medicine has a different development trajectory and utilization characteristics from modern medicine， there is certain differences in terms of evidence composition， retrieval and integration.This paper discussed multi-source body of evidence on Chinese patent medicine based on modern evidence-based medicine and ancient medical literature， and summarized the retrieval strategy as well as the possible problems and solving methods. For different types of evidence on Chinese patent medicine， the corresponding evaluation tools have been recommended， and the order to integrate the evidence based on the quality of the evidence from high to low is suggested. Finally， a multi-source based evidence retrieval-evaluation-integration scheme for Chinese patent medicine has been formed， which will provide a methodological reference for practitioners in the development of clinical practice guidelines for Chinese patent medicine.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 3）： Identification of Clinical Questions / 中医杂志

The identification of clinical questions for clinical practice guidelines of Chinese patent medicine （CPM） is important for subsequent evidence retrieval， evaluation of evidence quality， formation of recommendations. This paper described a methodological proposal for the identification of clinical questions for CPM guidelines to highlight the characteristics of Chinese patent medicine and reflect its effect in specific stage of the disease. Considering four aspects， namely， the drug of Chinese patent medicine （D）， the specific disease stage （S）， comparison （C）， and specific outcome （O）， DSCO framework has been proposed to formulate the clinical questions. Multi-source information through scientific research， policy or standard documents， and clinical data are suggested for collecting clinical questions， and clear selection criteria should be set to finalize the clinical questions to be addressed by the guideline. In addition， the above process needs to be transparently and publicly reported in order to ensure the clarity and completeness of the guidelines.

Application of Quality Evaluation of Blind Method in Clinical Trials of Traditional Chinese Medicine / 中国实验方剂学杂志

The quality evaluation of the blind method is to evaluate the clinical blind data obtained from clinical trials adopting the blind method and judge the effectiveness of the blind method by investigating the blind effect of different blind objects. A successful blind method can avoid the influence of subjective factors on the test results of subjects and researchers to a certain extent. The quality evaluation of the blind method can reflect not only the effectiveness of the blind method but also the accuracy and credibility of clinical trial results. In recent years， randomized controlled trials have been widely used in the evaluation of the clinical efficacy of traditional Chinese medicine （TCM）， but the quality of the implementation of blind methods is uneven， and the evaluation criteria have not yet been formed. In this paper， the data collection methods， calculation principles， advantages， and disadvantages of two quantitative quality evaluation methods of blind methods， namely James Blinding Index （JBI） and Bang Blinding Index （BBI）， were introduced. The two indexes were analyzed in a randomized controlled trial of acupuncture and moxibustion to relieve postoperative oral pain. The calculation process of the results was demonstrated by R software and visualized by forest map. At the same time， a tool table was designed to facilitate the collection of evaluation data of blind methods in TCM clinical trials at different stages. Finally， the necessity and feasibility of quality evaluation of blind method in TCM research were discussed to provide a basis for evaluating and improving the quality of blind method implementation in TCM clinical trials.
