SUMMARY: Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.
La pérdida parcial o total de dientes (edentulismo) se asocia a una disminución de la calidad de vida. Chile tiene grandes brechas socioeconómicas, que también se reconocen en la salud oral, pero se desconoce cómo ha evolucionado el edentulismo en el país. El objetivo de este estudio fue determinar el edentulismo en personas nacidas durante los siglos XIX y XX en Chile y fallecidas en el siglo XX, y compararlo con datos actuales del Ministerio de Salud de Chile (MINSAL) para observar su evolución en el país. Para ello, se analizaron 60 modelos 3D de cráneos de la Colección Osteológica Subactual de Santiago (30 individuos por sexo), en los que se analizó la presencia y ausencia de dientes en dentición antemortem en el maxilar. Se observó un alto porcentaje de pérdida dentaria, con un 65 % de edentulismo parcial y un 30 % de edentulismo total, y sólo un 5 % presentaba dentición completa en esta colección osteológica. Además, se encontró una disminución significativa a lo largo del tiempo; en 2017, la dentición completa a nivel país fue del 32,8 %. También se encontró una mayor frecuencia de edentulismo en las mujeres de la colección osteológica, con una probabilidad significativa del doble de edentulismo que en los hombres. Sin embargo, esta diferencia de sexo fue menor que la hallada en datos actuales. Este estudio es el primero que compara el edentulismo en Chile en dos épocas diferentes, ya que además de estudiarlo en los siglos XIX y XX, se realizó con datos de la actualidad y, en línea con investigaciones previas, revela la importancia de las variables socioeconómicas y de sexo en la pérdida dental.

Objective:To analyze the effect of different vascular access on the outcome in peripheral blood stem cells collection by a network Meta-analysis, and to provide a reference for clinical medical staff to select the best vascular access.Methods:A systematic search was carried out in Chinese Knowledge Infrastructure database (CNKI), Wanfang Database, VIP Database, Chinese Biomedical Literature Database, Cochrane Library, Web of Science, PubMed, Embase, from inception until April 15, 2023. Two researchers independently screened literature and extracted data. Bayesian network meta-analysis was performed using R4.2.2 and Addis-1.16.6 softwares.Results:A total 7 pieces of research were included, 5 vascular access methods were peripheral artery, peripheral vein, artery-vein, femoral vein-central venous catheter (FV-CVC), and internal jugular vein-CVC (IJV-CVC). The results showed that compared with the peripheral veins, there was no significant difference on CD34 cells between other vascular accesses in the primary outcome measure when collected peripheral blood stem cell collection. On the single blood volume treatment time, peripheral vein and IJV-CVC were statistically significant ( MD = 14.80, 95% CI 2.70-22.38, P<0.05) . The SUCRA ranking probability chart showed that on CD34 cells, FV- CVC>IJV-CVC>artery-vein>peripheral artery>peripheral vein access; for a single blood volume treatment time and monocyte number, peripheral artery was superior and the next was peripheral vein. Conclusions:Current evidence suggested that Peripheral artery may be the best vascular access in peripheral blood stem cells collection, which opens a new way to establish the vascular access for peripheral blood stem cells collection, but it needs to be confirmed by large clinic trials.

Objective:To investigate the correlation between gender, age, blood collection time, season and changes in cTnT concentration.Methods:In this study, 3548 patients (non-cardiovascular diseases) in Zhongshan Hospital of Fudan University were selected from 1 January to 31 December 2019. The basic data of the patients were collected, including gender, age, time of blood collection, medical history, clinical diagnosis, and results of cTnT testing. 1 840 males and 1 708 females were finally enrolled, with an age distribution of 65 (53, 75) years. The distribution of the data was assessed using the Kolmogorov-Smirnov (K-S) test, where non-normally distributed data were expressed as M( Q1, Q3). The Mann-Whitney U-test was used to compare cTnT concentrations between men and women, and to analyse the influence of gender on cTnT results. The Kruskal-Wallis test was used to compare cTnT levels between gender groups, to analyse the correlation between different times of blood collection, seasons, and other factors and cTnT concentrations. Result:cTnT concentrations increased with age in both males and females over the age of 60 years. cTnT levels were highest in individuals over the age of 90 years (0.028 ng/ml in males and 0.018 ng/ml in females). cTnT levels were higher in males (0.012 ng/ml) than in females (0.009 ng/ml) in all age groups ( H=6.340, P<0.01). The concentrations of cTnT varied at different time points of blood collection. In both males and females, cTnT concentrations reached a maximum at 8:00 and 13:00 (0.013 ng/ml and 0.012 ng/ml, respectively). Analysis of the physiological effect of season on cTnT secretion showed that cTnT levels were generally higher in spring and winter(0.012 ng/ml) than in summer and autumn(0.010 ng/ml). Conclusions:cTnT concentration is influenced by gender, age, time of blood collection and season. When analysing cTnT results in clinical practice, the gender and age of the individual should be taken into account, as well as the time point of blood collection and seasonal factors.

The composition and concentration of volatile organic compounds (VOCs) in exhaled breath are closely related to human health and the analysis of VOCs by collecting human exhaled breath has been widely used in disease surveillance research. This article reviewed the collection, enrichment, and detection methods of exhaled VOCs, which can provide a reference for selecting appropriate technology for follow-up research. The exhaled breath collection devices mainly include sampling bags for mixed exhaled breath and biological volatile organic compound (Bio-VOC) samplers for alveolar air. The pre-enrichment equipment included thermal desorption (TD), solid-phase microextraction device (SPME), and needle trap device (NTD). The detection methods of exhaled VOCs include gas chromatography-mass spectrometry (GC-MS), proton transfer reaction mass spectrometry (PTR-MS), selective ion flow tube mass spectrometry (SIFT-MS), and electronic nose. At present, the collection and enrichment technology of exhaled breath is not mature yet, and its influence on the results of detection is lack of evaluation. In the future, the research on collection and enrichment technology of exhaled breath should be strengthened to further promote the application of exhaled breath in disease surveillance research.

Occupational health risk assessment is a legal requirement. In legal terms, "occupational health risk assessment" is a means which focuses on occupational disease monitoring and special investigations, analyzing relevant information collected, and ultimately identifying high-risk industries and regions, and proposing reasonable, feasible, and scientific risk management and control recommendations to reduce occupational health risks in key industries and regions. The collection and selection of information are the foundation and core of occupational health risk assessment work. Causation determination is an important basis for information classification in occupational health risk assessment. The establishment and application of mathematical models are the prospects and directions for high-quality development of occupational health risk assessment work. However, the current research does not pay adequate attention on mathematical models for occupational health risk assessment methods, resulting in no substantial progression or improvement in occupational health risk assessment work. The key to future occupational health risk assessment work is to accurately grasp the definition of occupational health risk assessment in a legal term, to streamline and improve the indicator system of occupational health risk assessment, to actively explore and apply mathematical models for occupational health risk assessment, and to enhance the efficiency and accuracy of occupational health risk assessment work.

【Objective】 To retrospectively analyze the blood use of transfusion-dependent thalassemia (TDT) patients in 9 designated transfusion medical institutions from 2018 to 2023 in Nanning, and to evaluate the effect of " three designated " blood transfusion mode (hereby means TDT patients undergoing blood transfusion in designated transfusion medical institutions regularly) and " collection-based-supply" blood management mode on blood security of TDT patients. 【Methods】 The " three designated" blood transfusion mode was implemented to ensure that TDT patients registered in the local household registration (referred to as the " register" ) obtain the rights and interests of outpatient transfusion and blood security of designated medical institutions. The " collection-based-supply" blood management mode was implemented to assess the blood needs of "register" TDT patients and meet their needs to the maximum extent according to the blood inventory (collection). 【Results】 From 2018 to 2023, the total blood supply of "register" TDT patients was 10.37% of the total red blood supply of all medical institutions (138 509.5 U /1 335 788.0 U), with the highest proportion of type O blood as 46.34% (64 181.0 U/138 509.5 U) and the lowest proportion of type AB blood as 3.85% (5 331.0 U/138 509.5 U). In 2018, 9 transfusion medical institutions were designated for TDT patients.There were a total of 766 TDT patients in the register, with the per capita annual blood transfusion volume increased from 20.28 U (15 531.0 U/766 patients) in 2018 to 36.01 U (27 586.0 U/766 patients) in 2023, maintaining a positive growth every year(30.26%, 4.94%, 11.71%, 8.61%, 4.94% and 7.10%). 【Conclusion】 The " three designated" blood transfusion mode and the " collection-based-supply " blood management mode can effectively guarantee the blood supply of TDT patients.

ABSTRACT This article points out deficiencies in present-day definitions of public health surveillance, which include data collection, analysis, interpretation and dissemination, but not public health action. Controlling a public health problem of concern requires a public health response that goes beyond information dissemination. It is undesirable to have public health divided into data generation processes (public health surveillance) and data use processes (public health response), managed by two separate groups (surveillance experts and policy-makers). It is time to rethink the need to modernize the definition of public health surveillance, inspired by the authors' enhanced Data, Information, Knowledge, Intelligence and Wisdom model. Our recommendations include expanding the scope of public health surveillance beyond information dissemination to comprise actionable knowledge (intelligence); mandating surveillance experts to assist policy-makers in making evidence-informed decisions; encouraging surveillance experts to become policy-makers; and incorporating public health literacy training - from data to knowledge to wisdom - into the curricula for all public health professionals. Work on modernizing the scope and definition of public health surveillance will be a good starting point.
RESUMEN En este artículo se señalan las deficiencias de las definiciones actuales de la vigilancia de salud pública, que incluyen la recopilación, el análisis, la interpretación y la difusión de los datos, pero no las medidas de salud pública. El control de un problema de salud pública de interés exige una respuesta de salud pública que vaya más allá de la difusión de información. No es deseable que la salud pública esté dividida por un lado en procesos de generación de datos (vigilancia de salud pública) y por otro en procesos de uso de datos (respuesta de salud pública), gestionados por dos grupos diferentes (expertos en vigilancia y responsables de la formulación de políticas). Ha llegado el momento de replantear la necesidad de modernizar la definición de la vigilancia de salud pública tomando como referencia el modelo mejorado de Datos, Información, Conocimiento, Inteligencia y Sabiduría de los autores. Entre las recomendaciones que se proponen se encuentran las de ampliar el alcance de la vigilancia de salud pública más allá de la difusión de información para que incluya también el conocimiento aplicable (inteligencia); instar a los expertos en vigilancia a que presten ayuda a los responsables de la formulación de políticas en la toma de decisiones basadas en la evidencia; alentar a los expertos en vigilancia a que se conviertan en responsables de la formulación de políticas; e incorporar la formación en conocimientos básicos de salud pública (desde los datos hasta los conocimientos y la sabiduría) en los planes de estudio de todos los profesionales de la salud pública. Un buen punto de partida será trabajar en la modernización del alcance y la definición de la vigilancia de salud pública.
RESUMO Este artigo aponta deficiências nas definições atuais de vigilância em saúde pública, que incluem coleta, análise, interpretação e disseminação de dados, mas não ações de saúde pública. O controle de um problema preocupante de saúde pública exige uma resposta de saúde pública que vá além da disseminação de informações. A saúde pública não deve ser dividida em processos de geração de dados (vigilância em saúde pública) e processos de uso de dados (resposta de saúde pública) gerenciados por dois grupos distintos (especialistas em vigilância e formuladores de políticas). É hora de repensar a necessidade de modernizar a definição de vigilância em saúde pública, inspirada no modelo aprimorado de Dados, Informações, Conhecimento, Inteligência e Sabedoria dos autores. Nossas recomendações incluem: expansão do escopo da vigilância em saúde pública para além da disseminação de informações, de modo a abranger conhecimentos acionáveis (inteligência); obrigatoriedade de que os especialistas em vigilância auxiliem os formuladores de políticas na tomada de decisões baseadas em evidências; incentivo para que os especialistas em vigilância se tornem formuladores de políticas; e incorporação de capacitação em letramento em saúde pública (partindo dos dados para o conhecimento e em seguida para a sabedoria) nos currículos de todos os profissionais de saúde pública. O trabalho de modernizar o escopo e a definição de vigilância em saúde pública será um bom ponto de partida.

Introducción: La calidad de los datos facilita garantizar la fiabilidad de los estudios observacionales. Objetivo: Describir el aseguramiento y el control de calidad para mantener la fiabilidad y la validez del dato en un estudio de cohorte. Métodos: Presentar el manejo de datos implementado dentro de un seguimiento de enfermos renales crónicos cuya exposición fue un programa de protección renal comparado con el tratamiento convencional y su asociación con desenlaces clínicos. Se evaluó el cambio en la frecuencia de errores después de implementar el plan y la reproducibilidad del ingreso de registros a las bases de datos. Resultados: Se documentó una disminución progresiva en los errores cometidos en la captación de datos. El valor de Kappa entre los recolectores de la información para las variables clínicas más importantes fue 0,960 para la depuración de creatinina 150 mg/dL; 0,730 para la alteración del sedimento urinario; 0,956 para la asignación de estadio al ingreso. Los coeficientes de correlación intraclase para la identificación de las cifras de presión arterial sistólica fue 0,996; para la de presión arterial diastólica 0,993 y para los niveles de creatinina sérica al diagnóstico 0,995. Discusión: La calidad de los datos comienza con el reconocimiento de los retos y dificultades que implica su responsable captación, de ahí el aporte de la estandarización de los procesos y el personal que los lleve a cabo en forma idónea. Estudios evidencian que muchos procesos de mejora surgen en el desarrollo de la investigación sin protocolos preestablecidos. Conclusión: La reducción en la proporción y el tipo de error durante el proceso de captación de datos se debe a su identificación temprana y la corrección de instructivos, del instrumento de control de diligenciamiento y de la capacitación continua del personal. El análisis mostró una buena concordancia interevaluador.
Introduction: Data quality makes it easier to ensure that observational studies are reliable. Objective: To describe assurance and quality control to maintain data reliability and validity in a cohort study. Methodology: We present the data management strategies implemented in a study that followed patients of chronic kidney disease who were in a renal protection program and compared them with those undergoing conventional treatment to observe its association with clinical outcomes. We assessed the changes in error frequency after implementing the plan along with the reproducibility of the strategies for entering records into the databases. Results: We documented a progressive decrease of data collection errors. The Kappa values among data collectors for the most important variables were: 0.960 for creatinine clearance 150 mg/dl; 0.730 for urinary sediment alteration and 0.956 for stage allocation upon admission. The intraclass correlation coefficient for the identification of systolic blood pressure was 0.996; for diastolic blood pressure, the coefficient was 0.993 and for serum creatinine levels at diagnosis, the value was 0.995. Discussion: Data quality begins with the recognition of the challenges and difficulties involved in responsible data collection, hence the contribution of standardized processes and personnel to carry them out in a suitable manner. Studies show that many improvement processes arise in the development of research without pre-established protocols. Conclusion: The reduction in error ratio and type during the data collection process are the result of the early identification of erroneously entered or missing data, the correction of the guidelines for completing forms as well as of the instruments for detecting errors and continuous training of the staff. The analysis showed good inter-rater reliability.

Los captadores de niebla son usados para interceptar agua contenida en la niebla y abastecer de agua a comunidades que habitan en lugares donde este recurso escasea. Se evaluó el uso de captadores de niebla para la captación de agua en un área ubicada en el páramo Pan de Azúcar, Duitama-Boyacá. Se instalaron 60 captadores de niebla, 24 de ellos, con dispositivos para medir los volúmenes de agua interceptados. Los volúmenes de agua captados, se midieron en periodos de 24 horas, por 26 días, durante un año y se usó el modelo geométrico para diferenciar el agua proveniente de la niebla. La precipitación registrada fue mayor a la reportada en la literatura. La precipitación mensual osciló entre 51 y 1198 mm y la temperatura media mensual entre los 6 y 8 °C. Los volúmenes de agua promedio colectados por los 24 captadores de niebla estuvieron entre los 0,02 Lm-2dia-1 hasta los 4,4Lm-2dia-1. Los aportes de agua provenientes de la niebla oscilaron entre los 0,02 y 1,77 mmdía-1. La dirección del viento no afectó la captación de agua y aún se presenta incertidumbre al separar el aporte real de agua proveniente de la niebla a partir de la lluvia orográfica, lo cual, sigue siendo un desafío en los ecosistemas de páramo, por lo que se debe ampliar la investigación, para mejorar los diseños y las eficiencias de los captadores de niebla.
Fog collectors are used to intercept water contained in fog and supply water to communities that live in places where this resource is scarce. We evaluated the use of mist collectors to collect water in an area located in the Pan de Azúcar paramo, Duitama-Boyacá. We installed 60 mist collectors, 24 of them with devices to measure the volumes of water intercepted. The volumes of water captured were measured in periods of 24 hours for 26 days during one year and we used the geometric model to differentiate the water from the fog. The recorded precipitation was higher than that reported in the literature. Monthly rainfall ranged between 51 and 1198mm and mean monthly temperature ranged between 6 and 8°C. The average volumes of water collected by the fog collectors were below 0.5Lm-2day-1 with a maximum of 4.4Lm-2day-1. The contributions of water from the mist ranged between 0.02 and 1.77 mmday-1. The direction of the wind did not affect the capture of water and there is still uncertainty when separating the real contribution of water from the fog from the orographic rain, which continues to be a challenge in the paramo ecosystems, for which it is necessary to expand research, to improve the designs and efficiencies of fog collectors.

Os arquivos estão no centro de práticas e políticas contraditórias: por um lado, produção massiva, recolha imediata, exploração instantânea e publicação aberta; por outro lado, esquecimento, destruição ou negligência, e acesso fechado. O artigo ilustra essas contradições comparando, em primeiro lugar, três iniciativas de recolha de arquivos que permitiram e permitem recuperar o lugar do 'invisível' nas nossas sociedades, contra duas operações mais coletivas na sequência da tragédia francesa de 13 de Novembro de 2015 e dos períodos de confinamento. Depois da recolha, colocam-se questões relacionadas com as tensões geradas pela produção digital: como gerir o fluxo contínuo, a exigência de imediatismo, o recuo da presença humana? Finalmente, num contexto em que coexistem políticas públicas de memória e medidas regulamentares destinadas a proteger o segredo de defesa e o direito ao esquecimento, como podem arquivistas e historiadores trabalhar em conjunto para garantir que esta memória possa ser restituída aos cidadãos?
Les archives sont au cÅur de pratiques et politiques contradictoires : d'un côté production massive, collecte immédiate, exploitation instantanée et publication ouverte ; de l'autre oubli, destruction ou négligence, fermeture de l'accès. L'article illustre ces contradictions en mettant tout d'abord en regard trois initiatives de collectes d'archives qui ont permis et permettent de restituer la place des « invisibles ¼ dans nos sociétés, face à deux opérations plus collectives par suite du drame français du 13 novembre 2015 et des périodes de confinement. Après la collecte viennent les questions relatives aux tensions générées par la production numérique : comment gérer le flux continu, la demande d'immédiateté, le recul de la présence humaine ? Enfin, dans un contexte où voisinent politiques publiques mémorielles et dispositifs réglementaires destinés à protéger le secret-défense et le droit à l'oubli, comment peuvent travailler archivistes et historiens pour que cette mémoire puisse être restituée aux citoyens ?
Archives are at the heart of contradictory practices and policies: on the one hand, massive production, imme-diate collection, instantaneous exploitation, and open publication; on the other, forgetfulness, destruction or negligence, and closure of access. The article illustrates these contradictions by, first of all, comparing three archive collection initiatives that have allowed and allow us to restore the place of the 'invisible' in our societies in the face of two more collective operations following the French drama of November 13, 2015, and the confinement periods. After the collection come the questions relating to the tensions generated by digital production: how to manage the continuous flow, the demand for immediacy, and the declining human presence? Finally, in a context where public memorial policies and regulatory measures intended to protect defense secrecy and the right to be forgotten coexist, how can archivists and historians work to restore this memory to citizens?

Background: Medical record document explains all the details about the patient’s history, clinical findings, diagnostic test results, pre- and post-operative care, patient’s progress, and medication given. If written correctly, notes will support the doctor about the correctness of treatment. Aim and Objectives: Our objective was to study effectiveness and utility of medical record department at our medical college affiliated tertiary care institution. Materials and Methods: We did an observational study to determine various parameters of medical records such as consent, history and examination findings, pre-operative and intraoperative records, investigation documentation, nursing care chart, and concerned medical person’s signature. The study included 300 files. A medical record checklist was used as a tool for data collection. The study was conducted between January 2021 and January 2022. Data were collected, entered in Microsoft Excel spread sheet, and analyzed using percentage. Results: Out of the 300 files, 186 files belonged to different surgical specialties while the rest were of non-surgical fields. It was found that nursing assessment document was present in 78%, while discharged card copy was found attached in 75.33% files. Furthermore, surgical safety checklist was found in 89.24%, while signature of faculty was absent in 38.3% files. Conclusion: Medical record maintaining and keeping is an essential and vital part of health-care infrastructure, not only for data collection but also for calculating use of resources needed for better delivery of quality services to patients.

Ethnic medicine has a rich history of application. Because of the large number of ethnic groups, wide geographical distribution, and unique medical systems in China, the research on the human use experience(HUE) of ethnic medicine should combine the characteristics of ethnic medicine, be based on practical experience, and respect folk practice and tradition. The clinical positioning of ethnic medicine should consider three factors, i.e., population region, dominant diseases, and clinical demand. We should consider the development of traditional preparations that meet the needs of ethnic regions and encourage the development of new drugs that can be popularized and used nationwide for the dominant diseases of ethnic medicines. Attention should be paid to the problems such as a large number of customary articles or substitutes of ethnic medicinal materials, the phenomena of foreign bodies with the same name and different names for the same substance, the different standards of medicinal materials, and the poor processing standards. The name, processing method, source, medicinal parts, and dosage of ethnic medicinal materials or decoction pieces should be determined, and resources should be carefully evaluated to ensure the safety of medicinal resources and ecology. The preparation of ethnic medicine is mostly in the form of pills, powder, ointment, etc., with simple processing technology. The problems of low-quality stan-dards of some preparations, different prescriptions with the same name, and inconsistent processing technology should be overcome, and the process route and main process parameters should be clarified to lay the foundation for the subsequent empirical research on HUE. In the collection and analysis of the HUE data of ethnic medicine, the core guiding ideology of "patient-centered" should be established, and the experience data of patients should be collected. The problems of weak links existing in the inheritance of ethnic medicine should be solved, and flexible and diverse methods should be adopted. Meanwhile, on the premise of complying with the requirements of the principles of medical ethics, we should respect the religion, culture, and customs of ethnic areas to obtain the key HUE information of ethnic medicine. On the basis of the patient preference information and differences in regional disease epidemiology, population characteristics, and medical practice, whether the HUE conclusions of ethnic medicine can be extrapolated to patients outside the region is evaluated from the aspects of clinical benefits, risk tolerance, risk acceptance, etc. The HUE research on ethnic medicine is carried out in a clear way to guide the research and development of new ethnic medicines.

@#Introduction: Advancement in digital technology opens new doors for food safety auditors when it comes to performing food safety audits. Surge of Covid cases since year 2020 has seen an unprecedented switch to remote auditing by the Food Safety and Quality Programme under the arm of Ministry of Health in Malaysia. Methods: This paper presents the use of QGIS, an open-source cross-platform for geographic information system (GIS) to store, manage and visualise 2 types of data, i.e. real time data collected via a mobile device using QField, an open-source mobile application and also fixed data retrieved from existing database. New data from obtained from field sampling and surveillance presents updated information for food safety auditing and enforcement purposes. A total of 4972 datasets were obtained from the Ministry of Health’s Food Safety and Quality Division database on food factories from all 13 states and 3 federal territories in Malaysia. These datasets were transformed and stored into QGIS point layer for performing data classification analysis on clustering of HACCP, GMP and MeSTI certifications. Results: The Penang state has the most HACCP certified companies in fish and fish product category, Selangor is the highest for confectionery industry and Sabah for food services. The general output of mobile GIS provides a big picture of distribution of food safety certifications in Malaysia while more specific adoption of QField can assist in effective field work planning for enforcement officers and auditors leading to cost calculation via information on location, distance and time. Conclusion: QGIS application for spatial and temporal visualisation of data benefits the food safety auditing in Malaysia

Objective:To analyze the clinical characteristics of obese adolescents undergoing metabolic and bariatric surgery for the purpose to guide clinical decision-making and practice of metabolic and bariatric surgery in adolescents.Methods:The perioperative clinical profile of 123 adolescent patients under the age of 21 years who underwent metabolic and bariatric surgery in Beijing Friendship Hospital, Capital Medical University from 2018 to 2021 were extracted, and compared their clinical data with the overall data of 6807 patients in the 2021 GC-MBD Annual Report. Analyzed the clinical characteristics of adolescent weight loss metabolic surgery patients from multiple aspects such as preoperative complications, surgical methods, surgical outcomes, and follow-up. Statistical analysis was conducted using SPSS25.0 software.Results:Among adolescent bariatric surgery patients, the proportion of female patients (74.0%) was higher than that of male patients (26.0%). Except for the incidence of polycystic ovary syndrome (31.9%), which was higher than the overall rate, the proportion of other related diseases or symptoms was low and usually mild. The changes of systolic blood pressure ( Z=-5.73, P<0.001), body weight ( Z=-5.69, P<0.001), umbilical abdominal circumference ( Z=-2.40, P=0.017), glycosylated hemoglobin ( Z=-5.23, P<0.001), fasting insulin ( Z=-2.95, P<0.003), fasting C-peptide ( Z=-4.59, P<0.001), triglyceride ( Z=-2.75, P=0.006) at 3 months after operation were statistically significant compared with those before operation. The changes of systolic blood pressure ( Z=-3.42, P=0.001), body weight ( Z=-5.14, P<0.001), umbilical abdominal circumference ( Z=-2.86, P=0.004) and glycosylated hemoglobin ( Z=-2.67, P<0.008), fasting C-peptide ( Z=-2.09, P=0.037), high-density lipoprotein ( Z=-2.08, P=0.038) at 6 months after operation were statistically significant compared with those before operation. Conclusions:The outcomes of bariatric surgery in obese adolescents are similar to those in adults. The indications and timing of bariatric surgery need to be further explored. In view of the high proportion of females, poor self-management ability and low follow-up compliance of adolescent patients, it is urgent to construct a full-cycle care model suitable for adolescent patients with bariatric surgery to improve their self-management ability, follow-up compliance and long-term clinical outcomes.

Objective:To study the clinical value of bladder stimulation technique (BST) for clean-catch urine collection in late newborns.Methods:From November 2020 to March 2022, relatively stable late newborns hospitalized in the Department of Neonatology of our hospital were enrolled in the prospective randomized controlled trial. The newborns were assigned into BST group and control group. In BST group, urine was collected using BST (suprapubic tapping alternating with lumbosacral massage for 5 min) 20~30 min after feeding and specimen were collected using urine bag before and after BST. In the control group, urine was collected using urine bag method. The urine collection was considered successful if >1 ml of urine not contaminated by faeces were collected within 60 min. The t-test and χ 2 test were used for data analysis. Results:A total of 231 late newborns were included with 117 cases in BST group and 114 in control group. The rate of successful urine collection in BST group was higher than control group (65.8% vs. 39.4%).The time needed for successful urine collection [(30.2±8.5) min vs. (40.7±12.9) min], the incidences of faeces contamination (2.5% vs. 21.1%) and urine contamination (11.7% vs. 26.7%) in BST group were all significantly lower than control group(all P<0.05). Male and female newborns in BST group had similar success rates of urine collection (65.6% vs. 66.0%). Male newborns in BST group had similar urine contamination rate with control group (9.5% vs. 11.5%) and female newborns in BST group had significantly lower urine contamination rate than control group (14.3% vs. 47.4%, P<0.05). Urine was successfully collected in 71 newborns in BST group with median duration of BST for 81 (61,132) s. No adverse effects were observed except for transient consolable crying. Conclusions:Compared with urine bag collection method, BST improves successful urine collection rates and reduces the time needed for urine collection and urine contamination rates (especially for females).

Objective:To investigate the collection efficiency of peripheral blood hematopoietic stem cells and explore its influencing factors.Method:The parameters of the collection process, blood routine indexes and the number of MNC and CD 34+ cells of the product were detected by Fresenius blood cell separator, Mindray blood cell analyzer and BD flow cytometer. A retrospective analysis was performed on 72 patients who underwent autologous peripheral blood hematopoietic stem cell transplantation in Southwest Hospital of Army Medical University from January 2013 to January 2021, including the correlation among gender, age, blood routine indexes, collection circulation volume and MNC and CD 34+ cell count in these cases, and influence of various factors on collection efficiency of peripheral blood stem cells. The correlation among gender, age, blood routine indexes, collection circulation volume and MNC and CD 34+ cell count in 72 cases of autologous transplantation patients, and influence of various factors on collection efficiency of peripheral blood stem cells were analyzed retrospectively. Results:There were no significant differences in collecting efficiency of peripheral blood stem cells among patients with different age, sex and disease type ( P>0.05). The collected MNC count of all patients was positively correlated with the collection cycle count ( r = 0.33, P<0.001) and WBC count after mobilization ( r = 0.41, P<0.001). The number of CD 34+ cells collected was positively correlated with MNC count after mobilization ( r = 0.38, P<0.001) and the amount of white membrane collected ( r = 0.48, P<0.001). Logistic multivariate regression analysis showed that MNC count after mobilization: P<0.001, 95% CI 0.07(0.05 - 0.09), collection cycle amount [ P<0.001, 95% CI 0.00(0.00 - 0.00)] and postharvest total amount [ P<0.001, 95% CI 0.07(0.05 - 0.10)] were the influencing factors of the collected MNC number. Meanwhile, these factorswere also the influencing factors of the collected CD 34+ number (MNC count after mobilization: P<0.001, 95% CI 0.09(0.04 - 0.14); collection cycle amount: P = 0.003, 95% CI 0.00(0.00 - 0.00); postharvest total amount: P = 0.005, 95% CI 0.08(0.03 - 0.14)). Conclusions:The collection efficiency of peripheral blood stem cells varies greatly among individuals. The more MNC counts after mobilization, the more peripheral blood stem cells could be collected. In order to obtain high collection efficiency, it is necessary to adjust the parameters of peripheral blood MNC before collection, and pay attention to the collection circulation quantity, postharvest total amount and white membrane volume.
