La autopsia psicológica en Colombia: ¿Concepto o procedimiento para la investigación científica? Una revisión sistemática

Introducción: La literatura científica reporta que la autopsia psicológica desde sus inicios fue utilizada con la finalidad de ayudar a determinar las circunstancias de muerte de una persona, no obstante, en la actualidad se acoge más como concepto que como una herramienta procedimental. Objetivo: Establecer si en Colombia se ha utilizado para reconstruir los aspectos pre mortem de quienes han fallecido en extrañas circunstancias, de acuerdo con la finalidad de esta. Metodología: Se realizó una revisión sistemática de la literatura científica en 10 bases de datos; se emplearon como palabras clave "autopsia psicológica" y "Colombia", bajo una ventana de observación entre 2010 al 2021; por medio del método PRISMA. Resultados: Se evidencia que en Colombia durante los últimos 10 años el número de estudios asciende a 19, publicados en bases de datos, de los cuales 16 no emplearon el procedimiento de autopsia psicológica y solo tres de ellos sí lo hicieron. Discusión: Existe una tendencia a emplear la autopsia psicológica como concepto desde un enfoque clínico para respaldar los análisis retrospectivos, que, como técnica o procedimiento, se distancia de la posibilidad de reconstruir la criminodinámica del delito, así como la reconstrucción de aspectos de la personalidad, el estado mental y el estilo de vida de quién ha fallecido. Conclusiones: Se resalta que en Colombia la autopsia psicológica se ha utilizado exclusivamente en el campo clínico, sin el rigor científico, metodológico y sin la validez del protocolo empleado.

Introduction: The scientific literature reports that psychological autopsy from its beginnings was used with the purpose of helping to determine the circumstances of death of a person, however, it is currently embraced more as a concept than as a procedural tool. Objective: to establish if in Colombia it has been used to reconstruct the pre-mortem aspects of those who have died under strange circumstances, according to its purpose. Methodology: a systematic review of the scientific literature was carried out in 10 databases, using as keywords psychological autopsy and Colombia, under a window of observation between 2010 and 2021; using the PRISMA method. Results: they show that in Colombia during the last 10 years the number of studies published in databases amounts to 19, of which 16 did not use the psychological autopsy procedure and only three of them did. Discussion: There is a tendency to use psychological autopsy as a concept from a clinical approach to support retrospective analyses rather than as a technique or procedure, distancing us from the possibility of reconstructing the criminodynamics of the crime, as well as reconstructing aspects of the personality, mental state and lifestyle of the deceased. Conclusions: it is highlighted that in Colombia the psychological autopsy has been used exclusively in the clinical field, without the scientific and methodological rigor and without the validity of the protocol used.

The use of citizen information in criminal investigation through a collaborative technological innovation process to counteract theft from the person in Bogotá / El uso de la información ciudadana en la investigación criminal mediante un proceso de innovación tecnológico colaborativo para contrarrestar el hurto a personas en Bogotá / O uso da informação dos cidadãos na investigação criminal através de um processo colaborativo de inovação tecnológica para combater o roubode pessoas em Bogotá

Theft from the person is one of the highest impact crimes in Bogotá, with a national share of approximately 38 %. This crime brought to the attention of the authorities is referred to by academics as recorded or reported crime and is used by the police for different purposes, particularly for criminal investigation, but with inefficient results in the identification of perpetrators. Therefore, the type of research is qualitative and has the objective of linking the citizen through a process of collaborative technological innovation, with the purpose of collecting, processing and analysing reported or non-reported information (hidden crime) in a timely, anonymous and efficient manner with disruptive technologies prioritized for the project.The methodology used begins with the discovery stage by identifying key actors and building user stories. Then, in the understanding stage, the value proposition is put forth by means of a hypothesis that is validated in a process of experimentation, and finally, in the build stage, a technology watch analysis is carried out and the proposal for the collaborative system between the citizen and the police with a technological approach is put forward. The results are based on the identification and prioritization of five technologies, two actors, three variables and application of six low and medium fidelity prototypes, as well as the acceptance of citizens in collecting and sharing timely information at 87 %; that information focuses on video, audio, photos and localization at 55 %.On the other hand, with the entry into operation of the collaborative system, the researchers indicate that it would optimise investigation by 50 % through the timely identification of the perpetrators. As for the conclusion, the information analyzed and obtained from the results allows to reach, in a first phase, validation of the established hypothesis, but at the same time recognising the importance of including methodologies such as System Dynamics that allow for the systemic analysis of the information established by other actors and its impact on the proposed collaborative system.The use of citizen information in criminal investigation through a collaborative technological innovation process to counteract theft from the person in Bogotá

El hurto a personas es uno de los delitos de mayor impacto en temas de seguridad para Bogotá con una participación a nivel nacional del 38 % aproximadamente. Este delito puesto en conocimiento de las autoridades es denominado por académicos como criminalidad registrada o denunciada y es utilizada por la institución policial para diferentes fines, en especial para la investigación criminal, pero con resultados poco eficientes en la identificación de victimarios. Por lo tanto, el tipo de investigación es cualitativa y tiene como objetivo vincular al ciudadano mediante un proceso de innovación tecnológico colaborativo, con el propósito de recolectar, tratar y analizar información denunciada y no denunciada (criminalidad oculta) de manera oportuna, anónima y eficiente con tecnologías disruptivas priorizadas para el proyecto. La metodología empleada inicia con la etapa de descubrir mediante la identificación de actores claves y la construcción de historias de usuario. Luego, en la etapa comprender se plantea la propuesta de valor mediante una hipótesis que se valida en un proceso de experimentación, y por último en la etapa construir, se realiza un análisis de vigilancia tecnológica y se plantea la propuesta del sistema colaborativo entre el ciudadano y la policía con enfoque tecnológico. Los resultados se basan en la identificación y priorización de cinco tecnologías, dos actores, tres variables y aplicación de seis prototipos de baja y mediana fidelidad, así como la aceptación de la ciudadanía en recolectar y compartir información oportuna en un87 %, esa información se centra en videos, audios, fotos y localización con un 55 %. Por otro lado, con la entrada en funcionamiento del sistema colaborativo, los investigadores indican que optimizaría la investigación en un 50 % mediante la identificación oportuna de los victimarios. En cuanto a la conclusión, la información analizada y obtenida de los resultados, permite llegar en una primera fase, a validar la hipótesis establecida, pero a la vez, la importancia de incluir metodologías como la Dinámica de Sistemas que permita el análisis sistémico de la información establecida por otros actores y su impacto en el sistema colaborativo propuesto.

¿Son fiables las ruedas de reconocimiento como prueba de identificación del autor de un delito? Una revisión de meta-análisis y estudios experimentales / Are police line-ups reliable as evidence of perpetrator identification? A review of meta-analyses and experimental studies / As rodas de reconhecimento são confiáveis como prova de identificação do autor do crime? Uma revisão de metanálises e estudos experimentais

La rueda de reconocimiento es una diligencia de investigación policial orientada a identificar al autor de un crimen. Se trata de una práctica relativamente frecuente que puede tener como resultado consolidar sospechas o también descartar líneas de investigación. La rueda de reconocimiento suele estar precedida de la exposición de un álbum de fotos y también es frecuente solicitar al mismo testigo que haga una descripción o un retrato robot del atacante. Existen fundadas sospechas de que la concatenación de estas diligencias policiales de identificación desvirtúa la eficacia de la declaración del testigo presencial para elegir al verdadero culpable, en caso de que esté presente en la rueda. También existen algunas controversias con respecto a la fiabilidad de la rueda de reconocimiento en función de la edad del testigo, del número de personas que la conforman, del procedimiento para llevarla a cabo, entre otras. Con el objetivo de acotar la evidencia empírica en torno a estas cuestiones, se presenta una revisión de estudios meta-analíticos y diversos estudios experimentales, desde los cuales se han podido identificar los procedimientos más adecuados para optimizar la eficacia en la precisión de la declaración de los testigos presenciales de un delito en el contexto de una rueda de reconocimiento.

The line-up is a police investigative procedure aimed at identifying the perpetrator of a crime. It is a relatively common practice that can result in consolidating suspicions or ruling out lines of investigation. The identification parade is usually preceded by the exhibition of a photo album and it is also common to ask the same witness to make a description or sketch of the perpetrator. There are strong suspicions that the concatenation of these police identification steps undermines the effectiveness of the eyewitness statement in identifying the real culprit, if present at the line-up. There is also some controversy regarding the reliability of the identification parade, depending on the age of the witness, the number of people involved, the procedure for carrying it out, among others. In order to narrow down the empirical evidence on these issues, a review of meta-analytical studies and various experimental studies is presented, based on which it has been possible to identify the most appropriate procedures to optimise the effectiveness in the accuracy of eyewitness testimony in the context of a line-up.

Há também alguma controvérsia quanto à confiabilidade da roda de reconhecimento, dependendo da idade da testemunha, do número de pessoas envolvidas, do procedimento para realizá-la, entre outros. A fim de restringir as evidências empíricas sobre essas questões, é apresentada uma revisão de estudos metanalíticos e experimentais, a partir dos quais foi possível identificar os procedimentos mais adequados para otimizar a eficácia na precisão do depoimento de testemunhas oculares no contexto de uma roda de reconhecimento.

Clinicopathological correlation of various prostatic lesions with serum prostate-specific antigen level – A hospital-based cross-sectional study

Background: The prostate is a male reproductive accessory gland which gives rise to several pathological conditions. The present study aims to study the correlation of histopathology of prostatic diseases with the clinical profile of the patient coming to VSS Medical College (VSSMC), Burla for histopathological reporting of prostatic biopsies. Aim and Objectives: The objectives of this study were as follows: (1) To correlate serum prostate-specific antigen (PSA) level with various clinical and pathological lesions of the prostrate gland, in a Hospital-based sample of Western Odisha population. (2) As the male gender represents almost half of the entire population, to find out different clinicopathological lesions, percentage-wise, so as to know the frequency of occurrence of such lesions. Materials and Methods: Fifty-seven cases of prostatic diseases were recorded in the Department of Pathology, VSSMC, Burla for histopathological examination of prostatic tissue for 2 years from September 2017 to August 2019. All the samples were fixed in 5 ? sections with 10% neutral buffered formalin. Then Hematoxylin and Eosin stain (H and E stain) was used for staining. Appropriate clinical data comprising signs and symptoms, laboratory findings, and serum PSA levels were recorded. Results: The present study, in the beginning, consisted of 64 patients, out of which seven patients were excluded by exclusion criteria, and finally, 57 cases were analyzed. The most prevalent age group for all prostatic diseases was 61–70 years with a mean of 67 years. The majority of the cases (73.67%) were benign mostly benign prostatic hyperplasia (BPH). Prostatic intraepithelial neoplasia (PIN) was 12.29% and malignant cases (all adenocarcinoma) were also 12.29%. All patients showed prostatomegaly. About 50% of cases suggestive of malignancy by digital rectal examination (DRE) were confirmed to be carcinoma by histopathological study. Serum creatinine level was raised in 16.27% of benign and 21.42% of premalignant and malignant conditions. Serum PSA level below 4 ng/mL were all benign and above 10 ng/mL were majority malignant conditions. However, at level 4–10 ng/mL, BPH and PIN cases were overlapped with cases of carcinoma. Conclusion: Benign prostatic hyperplasia is the most commonly encountered prostatic lesion. Serum PSA level <4 ng/mL is associated with benign conditions and more than 10 ng/mL is associated more with carcinomas. Although, investigations such as DRE and serum PSA estimation aid in diagnosis, a definitive diagnosis of benign and malignant lesions of prostate can be made by histopathological study of prostatic biopsies.

Analysis of current status and risk of development in occupational medical examination institutions in Guangdong Province / 中国职业医学

Objective: To analyze the status of occupational medical examination (OME) institutions in Guangdong Province and the critical control points affecting their future development. Methods: A total of 211 OME institutions registered in Guangdong Province were selected as the research subjects. Their current statue was investigated, and the risk assessment of their future development was carried out based on hazard analysis and critical control point theory. Results: The OME institutions were mainly concentrated in the Pearl River Delta, accounting for 72.0%. The public and private medical and health institutions accounted for 70.6% and 29.4% respectively. The filing rates of different OME categories from high to low in the order were physical factors, chemical factors, dust, other, radiation factors, biological factors (P<0.01), and the filing rates were 89.6%, 88.6%, 84.8%, 63.0%, 7.1% and 1.0%, respectively. The rates of excellence in the field assessment from high to low in the order were hearing atlas analysis personnel, lung function examination operators, chest film reading personnel, chief examination physician, technical director, quality director (P<0.01), and the rates of excellence were 49.4%, 26.2%, 20.6%, 10.8%, 8.2% and 4.6%, respectively. A total of 37 institutions did not submit OME information, of which 23 institutions did not carry out OME work after filing. The required diagnosis rate and confirmed diagnosis rate of suspected occupational diseases in 2020 were 34.3% and 55.3%, respectively. In 2021, the detection rate of suspected occupational diseases was only 1.1‰. Among the institutions with biological monitoring records, 64.1% did not participate in external quality assessment program in laboratory, and the unqualified rate of 38 participating institutions was 55.3%. The risk assessment results show that the future development of OME institutions needs to focus on private institutions, institutions that have not reported OME information, institutions that have missed diagnosis and missed reporting of suspected occupational diseases, institutions that have not participated in external quality assessment program in laboratory and core personnel such as quality managers, technical leaders, and main inspection physicians. Conclusion: OME institutions in Guangdong Province show the characteristics of centralized filing category, centralized filing region and centralized filing institution nature. Combined with the potential risks of OME institutional capacity building, it is necessary to implement classified management, strengthen information construction, supervision and management, implement post responsibilities, and promote the high-quality development of OME institutions.

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.

A novel lateral classification of osteonecrosis of femoral head based on CT recons-truction of necrotic area and its clinical verification / 中国修复重建外科杂志

OBJECTIVE@#To analyze the femoral head collapse and the operation of osteonecrosis of the femoral head (ONFH) in different Japanese Investigation Commitee (JIC) types, in order to summarize the prognostic rules of each type of ONFH, and explore the clinical significance of CT lateral subtypes based on reconstruction of necrotic area of C1 type and verify their clinical effect.@*METHODS@#A total of 119 patients (155 hips) with ONFH between May 2004 and December 2016 were enrolled in the study. The total hips consisted of 34 hips in type A, 33 in type B, 57 in type C1, and 31 in type C2, respectively. There was no significant difference in age, gender, affected side, or type of ONFH of the patients with differenct JIC types ( P>0.05). The 1-, 2-, and 5-year femoral head collapse and operation of different JIC types were analyzed, as well as the survival rate (with femoral head collapse as the end point) of hip joint between different JIC types, hormonal/non-hormonal ONFH, asymptomatic and symptomatic (pain duration >6 months or ≤6 months), and combined preserved angle (CPA) ≥118.725° and CPA<118.725°. JIC types with significant differences in subgroup surgery and collapse and with research value were selected. According to the location of the necrotic area on the surface of the femoral head, the JIC classification was divided into 5 subtypes in the lateral CT reconstruction, and the contour line of the necrotic area was extracted and matched to the standard femoral head model, and the necrosis of the five subtypes was presented by thermography. The 1-, 2-, and 5-year outcomes of femoral head collapse and operation in different lateral subtypes were analyzed, and the survival rates (with collapse of the femoral head as the end point) between CPA≥118.725° and CPA<118.725° hip in patients with this subtype were compared, as well as the survival rates of different lateral subtypes (with collapse and surgery as the end points, respectively).@*RESULTS@#The femoral head collapse rate and operation rate in the 1-, 2-, and 5-year were significantly higher in patients with JIC C2 type than in patients with other hip types ( P<0.05), while in patients with JIC C1 type than in patients with JIC types A and B ( P<0.05). The survival rate of patients with different JIC types was significantly different ( P<0.05), and the survival rate of patients with JIC types A, B, C1, and C2 decreased gradually. The survival rate of asymptomatic hip was significantly higher than that of symptomatic hip, and the survival rate of CPA≥118.725° was significantly higher than that of CPA<118.725° ( P<0.05). The lateral CT reconstruction of type C1 hip necrosis area was selected for further classification, including type 1 in 12 hips, type 2 in 20 hips, type 3 in 9 hips, type 4 in 9 hips, and type 5 in 7 hips. There were significant differences in the femoral head collapse rate and the operation rate among the subtypes after 5 years of follow-up ( P<0.05). The collapse rate and operation rate of types 4 and 5 were 0; the collapse rate and operation rate of type 3 were the highest; the collapse rate of type 2 was high, but the operation rate was lower than that of type 3; the collapse rate of type 1 was high, but the operation rate was 0. In JIC type C1 patients, the survival rate of the hip joint with CPA≥118.725° was significantly higher than that with CPA<118.725° ( P<0.05). In the follow-up with femoral head collapse as the end point, the survival rates of types 4 and 5 were all 100%, while the survival rates of types 1, 2, and 3 were all 0, and the difference was significant ( P<0.05). The survival rate of types 1, 4, and 5 was 100%, of type 3 was 0, and of type 2 was 60%, showing significant difference ( P<0.05).@*CONCLUSION@#JIC types A and B can be treated by non-surgical treatment, while type C2 can be treated by surgical treatment with hip preservation. Type C1 was classified into 5 subtypes by CT lateral classification, type 3 has the highest risk of femoral head collapse, types 4 and 5 have low risk of femoral head collapse and operation, type 1 has high femoral head collapse rate but low risk of operation; type 2 has high collapse rate, but the operation rate is close to the average of JIC type C1, which still needs to be further studied.

The following data were recorded: type of publication, language, authorship data, funding, year, publication area, journal data, and collaborating institutions. A descriptive analysis was carried out and network maps were elaborated, using the VOSviewer software. Forty-six documents were retrived; the majority were articles (n = 36, 78.26%), letters (n = 9, 19.57%) and case reports (n = 1, 2.17%); published in 30 scientific journals, mainly foreign. Greater contribution was observed in microbiology, virology and parasitology. Fotry-two collaborative institutions were involved. About 90% of the publications were not funded. A growth in the number of publications in different thematic areas has been noted in recent years, which demonstrates the commitment of FCCBB-UNPRG to research in the biomedical field and the training of researchers. The implementation of research policies including guidelines and/or directives is expected to achieve sustained increase in scientific production.

Teachers' profile in sustainability: association with personal and social responsibility in physical education classes / Perfil dos professores em sustentabilidade: associação com responsabilidade pessoal e social nas aulas de educação física

ABSTRACT This study aims to identify in a sample of future teachers the profiles of their perceptions, attitudes, and values towards sustainable development and to determine whether a specific profile is related to personal and social responsibility and positive behaviors in Physical Education classes. The sample comprised 372 students (Mage = 22.02±3.16 years; 66.67% girls) from the subject of Physical Education of the Degree of Teacher of Primary Education (Universities of Granada and Zaragoza). An initial cluster analysis revealed the existence of two different groups among future teachers: Cluster 1, "negative perception," represented by 36.3%, and Cluster 2, "positive perceptions" with 63.7% of the sample. Thus, almost 40% of the sample does not perceive the current environmental crisis. The relationship between the groups and the rest of the target variables was analyzed through one-factor ANOVA, finding that Cluster 2 students had higher values in all the dimensions of personal and social responsibility and positive behaviors than those of Cluster 1. Lastly, a discriminant analysis revealed that belonging to a certain university determined belonging to one of the two Clusters, with the values obtained by the sample from the University of Granada being higher than those from the University of Zaragoza.

RESUMO Este estudo tem como objetivo identificar em uma amostra de futuros professores os perfis de suas percepções, atitudes e valores em relação ao desenvolvimento sustentável e determinar se um perfil específico está relacionado à responsabilidade pessoal e social e a comportamentos positivos nas aulas de Educação Física. A amostra foi composta por 372 alunos (idade = 22,02±3,16 anos; 66,67% meninas) da disciplina de Educação Física do curso de Licenciatura em Educação Básica (Universidades de Granada e Zaragoza). Uma análise inicial de agrupamento revelou a existência de dois grupos diferentes entre os futuros professores: O Grupo 1, "percepção negativa", representado por 36,3%, e o Grupo 2, "percepções positivas", com 63,7% da amostra. Assim, quase 40% da amostra não percebe a atual crise ambiental. A relação entre os grupos e o restante das variáveis-alvo foi analisada por meio de uma ANOVA de um fator, que revelou que os alunos do Grupo 2 tinham valores mais altos em todas as dimensões de responsabilidade pessoal e social e comportamentos positivos do que os do Grupo 1. Por fim, uma análise discriminante revelou que o fato de pertencer a uma determinada universidade determinava o pertencimento a um dos dois grupos, sendo que os valores obtidos pela amostra da Universidade de Granada eram mais altos do que os da Universidade de Zaragoza.

Significado de los trastornos de voz. Un estudio cualitativo desde la mirada de profesores de enseñanza básica / Meaning of Voice Disorders. A Qualitative Study from the Perspective of Elementary School Teachers

Objetivo. El objetivo del presente estudio fue describir el significado que le otorgan a los trastornos de voz los profesores y cuáles son las motivaciones que los llevan a no consultar con un especialista. Método. Para tal propósito, se realizó un estudio cualitativo en el que participa-ron 16 profesores de enseñanza básica. La información fue obtenida mediante una entrevista semiestructurada, la cual fue grabada y luego transcrita para su posterior análisis. El estudio contó con la aprobación del comité de ética y el consentimiento informado de cada uno de los participantes. Resultados. En cuanto a los resultados, surgieron cinco categorías: Conocimiento de los problemas de voz; Entrenamiento formal y recursos vocales; Sintomatología vocal experimentada a lo largo de la carrera docente; Afectación de la calidad de vida; Tratamiento y abordaje de los problemas de voz. Todos los participantes tienen alguna noción de los problemas de voz, asociándolos principalmente con algún síntoma o molestia experimentada. La gran mayoría declara nunca haber recibido formación en cuanto al uso de la voz y expresan sentir que su voz ha ido cambiando a lo largo de los años de ejercicio profesional, volviéndose más grave o ronca. Destaca que en cuanto al tratamiento, quince de los participantes nunca han consultado con especialistas, sino que recurren a remedios caseros o populares. Conclusión. En conclusión, los profesores corresponden a uno de los grupos donde se presenta una alta prevalencia de trastornos de voz. Sin embargo, esto contrasta con la baja preocupación y el desconocimiento respecto al abordaje de este tipo de problemas

Aim. The objective of the present study was to describe the significance teachers give to voice disorders, and the reasons that dissuade them from consulting a specialist. Method. To achieve this objective, a qualitative study was carried out with the participation of 16 elementary school teachers. The information was obtained by semi-structured interviews, which were recorded and then transcripts were prepared for analysis. The study was approved by the Ethics Committee and an informed con-sent was signed by each of the participants. Results. Five categories emerged from the results: Knowledge of voice problems; Formal training and voice resources; Vocal symptoms experienced throughout the teaching career; Effects on quality of life; Treatment of and approach to voice prob-lems. All the participants had some notion of voice problems, which they associated mainly with some symptom or discomfort experienced. The great majority stated they had never received training in voice use; they felt that their voices had changed over the years of their professional careers, becoming deeper or hoarser. A striking finding was that fifteen of the participants had never consulted a specialist, but only used home or popular remedies. Conclusion. In conclusion, teachers form a group with a high prevalence of voice disorders; however, this contrasts with a low level of concern and a lack of knowledge about addressing such problems

Epidemiological investigation of a pulmonary tuberculosis outbreak involving six high schools / 预防医学

@#In September 2020, three pulmonary tuberculosis cases were identified during school physical examinations at a senior high school in a district (School B) of Hangzhou City. Immediate epidemiological surveys were performed by local district and Hangzhou Center for Disease Control and Prevention, and a pulmonary tuberculosis outbreak involving 9 cases in 6 schools were identified. All cases were once Grade 9 students in Class of 2019 at a junior high school (School A), and the source of infection might be a laboratory-confirmed cases (index case) in this class reported in April, 2019. Following exposure to index case, other cases developed disease onset or were screened after entering senior high schools. In November, 2020, tuberculin skin test and chest X-ray scan were performed to screen pulmonary tuberculosis among 43 students and teachers in a class of Grade 9 in Class of 2019 at School A, and 17 students strongly positive for tuberculin skin test were given prophylactic therapy. No pulmonary tuberculosis case were identified until June 2021. It is suggested that early epidemiological surveys facilitates the identification of the epidemiological correlation between cases. Active search for individuals with common exposure history and prophylactic therapy are required if a possible outbreak is found, which is helpful to avoid the spread of the outbreak.

Epidemiological investigation and management of a case of severe Chlamydia psittaci pneumonia / 上海预防医学

ObjectiveTo identify causal factors of a case of severe Chlamydia psittaci pneumonia in Yangpu District and provide a scientific basis for effective prevention and control. MethodsBasic information and epidemiological data of the patient were collected through telephone interviews and field epidemiological surveys. Specimens from the patient， close contacts and the environment were collected for pathogen detection. Metagenomics next-generation sequencing （mNGS） was used to identify unknown pathogens. ResultsA 65-year-old male patient with a history of hypertension and diabetes was admitted to the hospital with symptoms of fatigue， poor appetite for a week， fever and cough for four days. A chest computer tomography （CT） scan showed scattered inflammation in the left lung with infiltration of multiple lobes. Blood gas analysis showed type I respiratory failure. The results of mNGS on the bronchoalveolar lavage fluid of the patient indicated that he was infected with Chlamydia psittaci. Epidemiological investigation showed a clear history of avian exposure， with an incubation period of 30 days. ConclusionThis serious pneumonia is a zoonotic disease caused by Chlamydia psittaci. A clear history of avian exposure and the use of mNGS technology can help in the timely diagnosis of this disease.

Under-reporting of mortality surveillance in Hainan, 2018-2020 / 中国热带医学

@#Objective　To understand the overall under-reporting of cause of death monitoring in Hainan Province, and to provide a scientific basis for evaluating the data from death registration report and health planning in Hainan. Methods　Multi-stage cluster random sampling was used, all towns/streets in cities and counties of the province were ranked from highest to lowest in terms of crude death rate, divided into high, medium and low levels (the number of each level was basically the same), and one was randomly selected from each level. A total of three towns/streets were used as survey areas, and all households in the area were survey households. Death information of resident population during 2018-2020 was collected and compared with routine surveillance data for the same period. The under-reporting rate was calculated, and comparison between groups was performed by chi-square. Results　A total of 12 583 death cases were investigated from 2018 to 2020, and the average mortality was 621.48/105. 4 809 cases were missed with the total under-reporting rate of 38.22%. The under-reporting rate from 2018 to 2020 were 39.75%, 39.99% and 34.77% (χ2=30.404, P<0.01) respectively. The under-reporting rate in eastern and central and western areas were 30.33%, 30.10% and 60.15% (χ2=931.901, P<0.01) respectively. The negative rate were different in different years old group (χ2=14.834, P<0.05). Of the 4 809 under-reported cases, as many as 93.49% died at home, and the composition of deaths in hospitals was about 10 times higher in the center than in the east and west, and the proportion of those who died in hospital in central areas was about 10 times higher than in eastern and central areas. Conclusions　More than half of the cities and counties in Hainan Province have improved the completeness of cause of death surveillance data. The under-reporting rate in age group <5 years are still high, and regular under-reporting investigations are still needed to strengthen the reporting and management of death information.

A investigation of pathogenic Yersinia enterocolitica infection in children with diarrhea under 5 years of age in western Yunnan / 中国热带医学

@#Abstract: Objective To investigate the prevalence and pathogenic characteristics of Yersinia enterocolitica infection in children with diarrhea under 5 years of age in western Yunnan, and to provide a basis for the prevention and treatment of infectious diarrhea in children. Methods Feces were collected from under five-year-old children with diarrhea in the First Affiliated Hospital of Dali University from 2020 to 2021. Clinical information of the cases was also collected. Yersinia enterocolitica was isolated from the samples after cold enrichment on selective culture plates, and the pathogenic characteristics of Yersinia enterocolitica were analyzed by biological type and serotype and virulence gene detection. Results A total of 397 feces were collected. Seven strains of Yersinia enterocolitica were isolated in three samples, and the prevalence of Yersinia enterocolitica infection was 0.76% (3/397). Among the three positive samples, two Yersinia frederiksenii or Yersinia intermedia were isolated in specimen No. 212 , and five Yersinia enterocolitica were detected in specimens No. 24 and 226. Two Yersinia enterocolitica isolated from one sample were biological type 1A, and the virulence gene test results were ail-/ystA-/ ystB+ /yadA-/virF-, which were non-pathogenic Yersinia enterocolitica. Three Yersinia enterocolitica isolated from the other sample were biological type 3, serotype O∶3 (rfbc+), and virulence gene detection results were ail+/ystA+/ystB-/yadA+ /virF+, which were pathogenic Yersinia enterocolitica. While pathogenic Yersinia enterocolitica was detected from feces of children with diarrhea at 11 months of age with a infection rate of 0.50%(2/397). Conclusion Sporadic infection of pathogenic Yersinia enterocolitica was found in under five-year-old children in western Yunnan Province. It is necessary to strengthen the monitoring and research of Yersinia enterocolitica.

Epidemiological investigation of an outbreak of anthrax in Gongliu County, Xinjiang Uygur Autonomous Region / 预防医学

Abstract@#A suspected case of cutaneous anthrax was reported by Gongliu County Disease Control and Prevention Center, Ili Kazak Autonomous Prefecture, Xinjiang Uygur Autonomous Region on August 19, 2021. Then, an epidemiological survey was performed by a joint investigation team consisting of professionals from Xinjiang Uygur Autonomous Region Center for Disease Control and Prevention, intermediate-level trainees from the Field Epidemiology Training Program of Chinese Center for Disease Control and Prevention, and professionals from Ili Kazak Autonomous Prefecture Center for Disease Control and Prevention. A total of 11 cutaneous anthrax cases were identified, including 8 suspected cases and 3 clinically diagnosed cases, and all cases were villagers in Y Village, X Township, Gongliu County, without severe case or deaths found. The onset of the first case occurred on July 27, and the onset of the last case occurred on August 16. The main clinical manifestations included ulcerative eschar on hands and exposed skin of the upper extremity. A Bacillus anthracis isolate was detected in meat samples from infected cattle. Epidemiological surveys showed that villagers did not report infected cattle to related sectors and privately slaughtered and ate meat from infected cattle without any effective protective measures, resulting in this outbreak. It is recommended to strengthen health education for people raising, selling and slaughtering livestock, and publicize zoonotic disease control knowledge, including anthrax, and establish an effective surveillance and response system for anthrax for immediate identification and treatment of epidemics.
