Challenges faced by frontline health managers during the implementation of COVID-19 related policies in India: A qualitative analysis

Background & objectives: The COVID-19 pandemic exposed the strengths and weaknesses of the healthcare systems across the world. Many directives, guidelines and policies for pandemic control were laid down centrally for its implementation; however, its translation at the periphery needs to be analyzed for future planning and implementation of public health activities. Hence, the objectives of this study were to identify the challenges faced by frontline health managers in selected States in India during the pandemic with regard to implementation of the COVID-19-related policies at the district level and also to assess the challenges faced by the them in adapting the centrally laid down COVID-19 guidelines as per the local needs of the district. Methods: A qualitative study using the grounded theory approach was conducted among frontline district-level managers from eight different States belonging to the north, south, east and west zones of India. The districts across the country were selected based on their vulnerability index, and in-depth interviews were conducted among the frontline managers to assess the challenges faced by them in carrying out COVID-19 related activities. Recorded data were transcribed verbatim, manually coded and thematically analyzed. Results: Challenges faced in implementing quarantine rules were numerous, and it was also compounded by stigma attached with the disease. The need for adapting the guidelines as per local considerations, inclusion of components of financial management at local level, management of tribal and vulnerable populations and migrants in COVID context were strongly suggested. The need to increase human resource in general and specifically data managers and operators was quoted as definite requirement. Interpretation & conclusions: The COVID-19 guidelines provided by the Centre were found to be useful at district levels. However, there was a need to make some operational and administrative modifications in order to implement these guidelines locally and to ensure their acceptability.

Establishment of A Quality Control Method for Simultaneous Determination of Multiple Active Components in Uygur Medicine of Nymphaeae Flos / 中国实验方剂学杂志

ObjectiveTo develop a quality control method for the simultaneous determination of multiple active components in Nymphaeae Flos aiming at the problems of the single index for quality control and the relatively low overall quality control level. MethodUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）was used to identify and select the index components for quality control with the mobile phase of 0.1% formic acid aqueous solution（A）-acetonitrile（B）for gradient elution （0-2 min， 3%-8%B； 2-4 min， 8%-10%B； 4-13 min， 10%-15%B； 13-19 min， 15%-20%B； 19-26 min， 20%-45%B） at a flow rate of 0.4 mL·min-1， detection wavelength of 350 nm， electrospray ionization（ESI）， negative ion scanning mode， ion source temperature of 120 ℃， scanning range of m/z 100-1 200， transmit collision energy of 6 eV for low-energy scanning and 25-50 eV for high-energy scanning. High performance liquid chromatography（HPLC）was used to establish the quality control method for the simultaneous determination of multi-index components with the mobile phase of 0.2% phosphoric acid aqueous solution（A）-acetonitrile（B） for gradient elution（0-30 min， 12%-15%B； 30-60 min， 15%-22%B； 60-90 min， 22%-40%B）and detection wavelength of 350 nm. The preparation method of the test solution for content determination was refluxing extraction for 60 min with 80 times the amount of 70% methanol. ResultBy comparing the retention time， ultraviolet absorption characteristics， MS and MS/MS spectrometric signals in the samples with the reference substances， 8 active components with high contents， including brevifolincarboxylic acid， ellagic acid， rutin， nicotiflorin， astragalin， quercetin， quercetin-3-methylether and kaempferol， were identified qualitatively from Nymphaeae Flos， which were selected as the index components for quality control. Under the established HPLC conditions， the above 8 components could be well separated（resolution>1.5）， and showed good linearity（r=0.999 9）between the concentration ranges of 1.99-99.6， 1.76-176， 1.52-75.8， 3.60-180， 0.964-96.4， 1.18-118， 1.94-96.8， 1.04-104 mg·L-1 and the peak areas， respectively. The detection limits of them were 10-49 μg·L-1， and the limits of quantitation were 34-164 μg·L-1. The average recoveries were 97.12%-103.1% with the relative standard deviations （RSDs） were 1.1%-2.2%. ConclusionA quality control method for simultaneous determination of the multiple active components in Nymphaeae Flos have been developed， which is simple， accurate and reproducible， and it can provide a scientific basis for the formulation of quality standard of this herb and lay a research foundation for the transformation of Uygur hospital preparations containing Nymphaeae Flos into new drugs.

Chemical components of Magnoliae Officinalis Cortex of different origins and with different tree ages before and after being processed with ginger juice:a qualitative and quantitative analysis / 中国中药杂志

This study aimed to investigate the impact of ginger juice on chemical profile of Magnoliae Officinalis Cortex(MOC) when they were processed together. Ultra-high-performance liquid chromatography coupled to quadrupole-orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) was used for qualitative analysis of the chemical component of MOC samples before and after being processed with ginger juice. UPLC was performed to observe the content variation of eight main components in processed MOC. A total of 174 compounds were identified or tentatively deduced from processed and unprocessed MOC samples according to MS data obtained in positive and negative ion mode. After MOC was processed with ginger juice, the peak areas of most phenolics increased, while the peak areas of most phenylethanoid glycosides decreased; as for neolignans, oxyneolignans, other lignans and alkaloids, changes in the peak area were variable, and the peak areas of terpenoid-lignans varied little. Additionally, gingerols and diarylheptanoids were only detected in the processed MOC sample. The contents of syringin, magnoloside A, and magnoloside B decreased significantly in the processed MOC sample while no significant difference was observed in the contents of magnoflorine, magnocurarine, honokiol, obovatol, and magnolol. This study comprehensively explored the content variation of chemical components in processed and unprocessed MOC samples derived from different regions and with different tree ages using UPLC and UHPLC-Q-Orbitrap HRMS, and summarized the variation characteristics of various compounds. The results provide a data foundation for further research on pharmacodynamic substances of MOC processed with ginger juice.

Qualitative Analysis of Metabolites of Aristolochiae Fructus Aqueous Extract in Rats / 中国实验方剂学杂志

ObjectiveBased on ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MSE） technique， we identified qualitatively the metabolites of aristolochic acid（AAs） in rat in order to analyze the metabolic differences between water extract of Aristolochiae fructus（AFE） and Aristolochic acid Ⅰ（AAⅠ）. MethodSD rats were selected and administered AFE（110 g·kg-1·d-1） or AAⅠ（5 mg·kg-1·d-1） by oral for 5 days， respectively. Serum， urine and feces were collected after administration. Through sample pretreatment， ACQUITY UPLC BEH C18 column（2.1 mm×100 mm， 1.7 μm） was used with the mobile phase of 0.01% formic acid methanol（A）-0.01% formic acid water（B， containing 5 mmol·L-1 ammonium acetate） for gradient elution（0-1 min， 10%B； 1-7 min， 10%-75%B； 7-7.2 min， 75%-95%B； 7.2-10.2 min， 95%B； 10.2-10.3 min， 95%-10%B； 10.3-12 min， 10%B） at a flow rate of 0.3 mL·min-1. Positive ion mode of electrospray ionization（ESI+） was performed in the scanning range of m/z 100-1 200. In combination with UNIFI 1.9.4.053 system， the Pathway-MSE was used to qualitatively analyze and identify the AAs prototype and related metabolites in biological samples（serum， urine and feces）， and to compare the similarities and differences of metabolites in rats in the subacute toxicity test between AFE group and AAⅠ group. ResultCompared with AAⅠ group， 6， 10， 13 common metabolites and 14， 20， 30 unique metabolites were identified in biological samples（serum， urine and feces） of AFE group， respectively. Moreover， the main AAs components always followed the metabolic processes of demethylation， nitrate reduction and conjugation. Compared with common metabolites in AAⅠ group， prototype components of AAⅠ in serum and most metabolic derivatives of AAⅠ［AAⅠa， aristolochic lactam Ⅰ（ALⅠ）a， 7-OHALⅠ and its conjugated derivatives］ in biological samples were significantly increased in AFE group（P<0.05， P<0.01）， except that the metabolic amount of ALⅠ in feces of AFE group was remarkably lowed than that of AAⅠ group（P<0.01）. In addition， a variety of special ALⅠ efflux derivatives were also identified in the urine and feces of the AFE group. ConclusionAlthough major AAs components in AFE all show similar metabolic rules as AAⅠ components in vivo， the coexistence of multiple AAs components in Aristolochiae Fructus may affect the metabolism of AAⅠ， and achieve the attenuating effect by increasing the metabolic effection of AAⅠ and ALⅠ.

Conclusion This method offers simplicity, good reproducibility, and stability, making it suitable for rapid qualitative analysis of volatile organic components in chemicals.

Research progress on three-dimensional evaluation methods for facial asymmetry / 口腔疾病防治

@#Facial symmetry evaluation has always been a hot topic of concern for doctors who engage in the study of facial beauty disciplines such as orthodontics, dentistry, and plastic surgery. Although scholars at home and abroad have carried out much research on the evaluation of facial symmetry with a variety of emerging technologies and methods, there is still a lack of unified standards for the evaluation of facial asymmetry due to the complexity of the content and methods and individual subjectivity. Facial asymmetry involves changes in the length, width and height of the face. It is a complex dental and maxillofacial malformation whose early identification and accurate evaluation are particularly important. Clinically, in addition to the necessary dental and maxillofacial examinations, it is also necessary to evaluate facial asymmetry with the help of corresponding auxiliary methods. This paper gives a summary of the commonly used three-dimensional evaluation methods. The evaluation methods of facial asymmetry can be divided into 5 categories: qualitative analysis, quantitative analysis, dynamic analysis, mathematical analysis, and artificial intelligence analysis. After the analysis and summarization of the characteristics, advantages and limitations of each method in clinical applications, it is found that although these methods vary in accuracy, evaluation scope, diagnosis nature and calculation method, etc., the three-dimensional evaluation methods are more objective, more accurate and more convenient and will become the mainstream evaluation method for facial asymmetry with further development of three-dimensional measurement technologies.

Apropiación de los elementos de innovación social en organizaciones comunitarias agropecuarias del departamento de Boyacá, Colombia / Appropriation of the elements of social innovation in community agricultural organizations of the department of Boyaca, Colombia

RESUMEN Con el objetivo de establecer criterios mínimos relativos a la innovación social en organizaciones comunitarias agropecuarias, se hizo uso de herramientas propias de la investigación cualitativa que incluyeron búsquedas especializadas y uso de programas para análisis de datos bibliográficos (por ejemplo VOSviewer™) para determinar los elementos relativos a la gestión, gobernanza, capacidades, modelo de negocio sostenibilidad para ocho (8) organizaciones comunitarias de productores agropecuarios de la provincia del Sugamuxi, en el departamento de Boyacá, Colombia. Se pudo establecer que algunas organizaciones de productores agropecuarios que ejercen actividades en el departamento de Boyacá no están apropiando de forma integral los elementos de innovación social (en niveles operativos y gerenciales) y, consecuentemente, existe toda una ruta de mejoramiento por desarrollar con estas para optimizar los índices de eficiencia organizacional; además, se evidencia la complejidad de la temática, dado que la sostenibilidad de las innovaciones sociales dependerá en gran medida de la gestión de las organizaciones, donde se establezcan agendas institucionales compartidas contextualizadas y ajustadas a los territorios. Es necesario optimizar los canales de participación de manera mancomunada entre el Estado, las organizaciones y los mismos productores para poder dinamizar procesos, metas y alcances reales de la innovación social a la luz de los acelerados cambios a los que se enfrenta el productor agropecuario agremiado en Colombia, relativos estos a la dinámica del mercado, el acceso a recursos y otros.

ABSTRACT In order to establish minimum criteria related to social innovation in agricultural community organizations, qualitative research tools were used, including specialized searches and the use of programs for the analysis of bibliographic data (for example VOSviewer™), with the purpose of defining the elements related to management, governance, capacities, business model and sustainability for eight (8) community organizations of agricultural producers in the province of Sugamuxi, in the department of Boyacá, Colombia. It was possible to establish that some organizations of agricultural producers that carry out activities in the department of Boyacá are not integrally appropriating the elements of social innovation (at operational and managerial levels) and, consequently, there is a whole route of improvement to be developed with them to optimize the organizational efficiency indexes; in addition, the complexity of the subject is evident, given that the sustainability of social innovations will depend largely on the management of the organizations, where shared institutional agendas contextualized and adjusted to the territories are established. It is necessary to optimize the channels of participation in a joint manner between the State, the organizations, and the producers themselves to be able to dynamize processes, goals and the real scope of social innovation in light of the accelerated changes faced by the agribusiness producer in Colombia, related to market dynamics, access to resources and others.

Representaciones sociales sobre el Programa Mais Médicos entre consejeros municipales de salud de Brasil / Social representations on Mais Médicos Program among municipal health councelors of Brazil

Introducción: La atención primaria de salud en Brasil se considera una prioridad. En el año 2013 se creó el Programa Mais Médicos, de formación en servicio y de ampliación de la cantidad de médicos en el país. La cooperación cubana, gestionada por la Organización Panamericana de la Salud fue quien envió la mayor cantidad de profesionales. Objetivo: Analizar las representaciones sociales de los consejeros de salud sobre el Programa Mais Médicos, en municipios en los que prestaron atención a su población médicos provenientes de Cuba. Métodos: Estudio de caso descriptivo de corte transversal abordado con metodología cualitativa. La muestra fue intencional. Se trabajó con 58 entrevistas semiestructuradas y el análisis fue realizado mediante el software gratuito Iramuteq con la técnica de análisis lexical. Resultados: Se pudo distinguir cuatro grupos de representaciones, sobre el funcionamiento de los consejos municipales de salud, sobre las representaciones del Programa Mais Médicos, sobre las redes de atención y sobre los médicos brasileños y cubanos. El estudio aporta evidencias de la aplicación de un nuevo modelo de atención para los consejeros que objetivaron y anclaron en el concepto de nacionalidad. El modelo cubano incorpora características de humanismo, atributos que no estaban contenidos en las representaciones sobre los médicos locales. Conclusiones: Las representaciones sociales sobre el Programa Mais Médicos aluden a una acción que mejora la calidad de los servicios, no obstante, la literatura sobre atención básica aún deja ver algunos problemas de acceso y tránsito por la red del sistema único de salud(AU)

Introduction: Primary health care in Brazil is considered a priority. In 2013, Mais Médicos Program was created, providing in-service training and expanding the number of doctors in the country. Cuban cooperation, managed by the Pan American Health Organization, sent the largest number of professionals. Objective: Analyze the social representations of health counselors on Mais Médicos Program, in municipalities in which doctors from Cuba cared to their population. Methods: Descriptive cross-sectional case study approached with qualitative methodology. The sample was intentional. It was conducted a work with 58 semi-structured interviews and the analysis was carried out using the free software Iramuteq with the lexical analysis technique. Results: Four groups of representations could be distinguished: on the functioning of the municipal health councils, on the representations of Mais Médicos Program, on the care networks and on Brazilian and Cuban doctors. The study brings evidence of the application of a new model of care for counselors who objectified and anchored in the concept of nationality. The Cuban model incorporates characteristics of humanism, attributes that were not contained in the representations about local doctors. Conclusions: The social representations on Mais Médicos Program allude to an action that improves the quality of services, however, the literature on basic care still shows some problems of access and transit through the network of the health system(AU)

Qualitative analysis of operational deliverables of the PGH-Child Protection Unit and Child Protection Network in advancing the care continuum for child maltreatment: A roadmap for setup and evaluation

Objective@#Our goal is to identify an operational roadmap of core elements in the set-up of the Philippines General Hospital Child Protection Unit (PGH-CPU) established in 1997, and Child Protection Network (CPN) established in 2002. This roadmap will guide future improvement needs for PGH-CPU and CPN and could help accelerate the set-up of future child protection units or networks. @*Methods@#Using the 5 pillars of the Care Continuum for Child Maltreatment for categorization of deliverables — multidisciplinary intervention, training, governance, research/publication, and prevention — we identified operational deliverables (excluding patient numbers and outcomes) of the PGH-CPU and CPN. These were qualitatively analyzed to identify trends across the past 20-years and along 5 pillars of the Care Continuum. @*Results@#Identification and qualitative analyses of documented deliverables reveal pillar-specific and time-dependent trends across 5-year periods. This trend analysis identified the core elements central to the set-up of a CPU and reveal an operational roadmap in the set-up of CPUs in resource-constrained settings. @*Conclusions@#Case study review and qualitative analyses identify core elements that comprise a roadmap for need based prioritization in the set-up of CPUs/CPNs towards a comprehensive care continuum for child maltreatment. The 20-year experience in a developing nation context validates the roadmap

Qualitative Analysis of Opinions on the Decisions Made by Community-dwelling Elderly People regarding Their Medical Treatment and Care in the End-of-life / 日本プライマリ・ケア連合学会誌

Introduction: The objective of this study was to identify the opinions of community-dwelling elderly people on medical treatment and care choices during the end-of-life period.Methods: Self-administered questionnaires were distributed to elderly people who participated in nursing care prevention projects implemented by two municipalities in the Kanto region. Analysis of the contents included in the free-description section of the questionnaire was conducted using a qualitative coding procedure.Results: Analysis of 135 responses in the free-description section of the questionnaire led to the development of the following four final categories: 1. end-of-life is an extension of daily life; 2. end-of-life does not belong solely to oneself; 3. consideration of loved ones; and 4. the desire to determine one's own end.Conclusion: This study identified the following: community-dwelling elderly people have a tangible feeling that "end-of-life is an extension of daily life." They experience conflicting feelings of "desire to determine their own end" and "end-of-life does not belong solely to themselves," they have thoughts that include "consideration of loved ones," which take the form of concern that, based on their experience, they will be a burden on their family and those around them.

Black carbon analytical methods for environmental samples and associated perspectives of biomonitoring / 环境与职业医学

Black carbon (BC) is the most strongly light-absorbing component of particulate matter and is largely emitted from the incomplete combustion of fossil and biomass fuels. It has a graphite structure with less carbonized, irregular, microcrystalline, and heterogeneous components, which is determined by pyrolysis conditions. BC can be absorbed by human body via inhalation or ingestion route and then be transported to various organs through the blood circulation system in human body. When crossing different biological barriers (such as blood-brain barrier, placenta barrier, and blood-testis barrier), BC may further act on these targets and induce various toxicities. This review first distinguished between BC and carbon black, and then introduced analytical methods of BC in various environmental samples: microscopic observation, chemothermal oxidation methods, other chemical oxidation methods, and molecular marker analysis. We summarized the principles, technical characteristics, and application to environmental samples of these methods, and discussed the ideas and perspectives of determination of BC in biological samples for human biomonitoring.

Evaluation of mobile emergency service with the use of mixed method / Avaliação do serviço móvel de urgência com o uso de método misto / Evaluación de la atención móvil de urgencias con el uso del método mixto

This is an evaluative study, with sequential explanatory mixed methods, aimed at evaluating the performance of the Brazilian Mobile Emergency Medical Service (SAMU) in the Grande ABC region, located in the state of São Paulo, Brazil. In the quantitative approach, an analysis of interrupted time series was performed to evaluate the immediate and gradual effects of the SAMU on hospital mortality due to acute myocardial infarction. The qualitative approach was conducted via semi-structured interviews and a thematic analysis was applied for the interpretation of the results, exploring the attitudes and values of the interviewees regarding the performance of SAMU in the Grande ABC region. Interrupted time series analysis showed a -0.04% reduction in the underlying mortality rate since SAMU implementation (95%CI: -0.0816; -0.0162; p-value = 0.0040) and a reduction in the mortality level, -2.89 (95%CI: -4.3293; -1.4623; p-value = 0.0001), both with statistical significance. To improve the robustness of the results, a control region was used, showing a statistically significant difference in the post-intervention result of -0.0639 (95%CI: -0.1060; -0.0219; p-value = 0.0001). The interviews revealed that the SAMU has the potential to intervene in the prognosis of transported cases, however, challenges related to the availability of beds, expansion of telemedicine, and continuous training of professionals for qualified emergency care in the event of a heart attack must be overcome. The results indicate that the studied intervention is part of a set of factors that, together, generate more conditions to achieve a better result.

Estudo avaliativo com uso de métodos mistos na tipologia explanatória sequencial cujo objetivo foi avaliar o desempenho do Serviço de Atendimento Móvel de Urgência (SAMU) na região do Grande ABC, Estado de São Paulo, Brasil. Na abordagem quantitativa, foi realizada análise de séries temporais interrompidas para testar os efeitos imediatos e graduais da intervenção sobre a mortalidade hospitalar por infarto agudo do miocárdio. A abordagem qualitativa foi realizada através de entrevistas semi-estruturadas, e a análise temática foi aplicada para a interpretação dos resultados, explorando as atitudes e valores dos entrevistados em relação ao desempenho do SAMU no Grande ABC. A análise de série temporal interrompida mostrou uma redução de -0,04% na taxa de mortalidade subjacente desde a implementação do SAMU (IC95%: -0,0816; -0,0162; p = 0,0040) e uma redução no nível de mortalidade, de -2,89 (IC95%: -4,3293; -1,4623; p = 0,0001), ambas estatisticamente significativas. Para melhorar a robustez dos resultados, foi utilizada uma região de controle, o que mostrou uma diferença estatisticamente significativa na tendência pós-intervenção de -0,0639 (IC95%: -0,1060; -0,0219; p = 0,0001). De acordo com as entrevistas, o SAMU tem o potencial de intervir no prognóstico dos pacientes transportados; entretanto, em casos de infarto agudo do miocárdio, diversos desafios precisam ser superados, relacionados à disponibilidade de leitos, expansão da telemedicina e capacitação permanente das equipes de atendimento qualificado em emergências. Os resultados indicam que a intervenção faz parte de um conjunto de fatores que, conjuntamente, geram mais condições para alcançar melhores resultados.

The initial sample consisted of 115 inputs, with 59 exclusions and 56 retained for the content analysis described by Bardin and multivariate analysis by frequency (p<0.05) in the IRaMuTeQ software. The guiding axes defined for the content analysis were Food and Nutritional Insecurity, Equity, School Environment, Importance of Primary Care, Responsibility for Policy Assurance, and Food and Nutrients. The overall profile of the participants was heterogeneous concerning the activity segment, with the highest representation being education and research institutions (38%). The inputs highlighted the concern of civil society in assuring food and nutrition security for the population of the Federal District. We observed that the diverse inputs associated with systematic analysis could support the elaboration of public policies more consistent with reality and strengthen its implementation, making it more tangible. Thus, society's participation in political decisions must be encouraged and expanded, as it is essential for democratization and equity.

Rapid identification of chemical constituents in the dried stem bark of Asparagus officinalis L. based on UPLC-Q-TOF-MS/MS / 药学学报

Ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) coupled with a molecular network analysis strategy was used to identify the chemical constituents of the stem bark of two kinds of asparagus. The chemical constituents were identified by determining an accurate molecular weight, the fragmentation pathway, and comparison with the mass spectrometry data from the references. A molecular network was established based on the similarity of MS/MS fragmentation patterns. A total of 107 compounds were identified or tentatively deduced, which included 46 saponins, 13 flavonoids, and 48 other compounds. The chemical compounds identified in the stem bark of white and green asparagus differed greatly: the white asparagus was rich in saponins, while the green asparagus was rich in flavonoids. In conclusion, the chemical constituents of asparagus stem bark were characterized rapidly using UPLC-Q-TOF-MS/MS and molecular network analysis, with 10 compounds and 45 targets determined from the HIT 2.0 herbal ingredients' targets platform. This work will provide a theoretical basis for the resource utilization of asparagus.
