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.

Quality issues in reviews written by medical postgraduate students: investigation and countermeasures / 中华医学教育探索杂志

Objective:To investigate the quality issues in medical reviews written by medical postgraduate students, and to provide a reference for improving the quality of medical reviews written by such students.Methods:A total of 141 medical reviews written by the medical postgraduate students from various affiliated hospitals of Shanghai Jiao Tong University School of Medicine from 2018 to 2022 were collected, and the quality of these medical reviews was evaluated in terms of topic selection and writing expression skills. As for topic selection, a self-designed innovative questionnaire (hereinafter referred to as topic questionnaire) was used to collect the evaluation of external experts, and as for writing expression, the reviews were assessed based on the criteria in relevant literature from the aspects of the outline of the review, the timeliness of references, analysis and evaluation, and the quality of the text. EPIDATA 3.2 was used to input data, and SPSS 20.0 was used for the chi-square test.Results:A total of 135 (96%, 135/141) valid questionnaires were collected in this study, and the results showed that 70% (94/135) of the review topics lacked novelty. The assessment of writing skills showed that 95% (128/135) of the reviews had outdated references, and 68% (92/135) lacked focus, hierarchy or logic in outline, which accounted for a higher proportion than the reviews with analysis and evaluation issues (59%, 80/135) and text quality issues (61%, 83/135) ( P<0.05). Conclusion:There are many quality issues in the medical reviews written by medical postgraduate students, such as a lack of novelty in topic selection and low overall quality of outlines. In order to improve the abilities of scientific research among medical postgraduate students, universities and supervisors should strengthen the guidance of innovative thinking in topic selection and enhance the training of writing expression skills, such as scientific analysis and logic.

And the students considered the opening experiments of setting up professional courses was sufficient and necessary. Conclusion:Carrying out opening experiments for students majoring in preventive medicine is helpful to improve students' professional quality and cultivate their practical ability and scientific research ability.

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.

@#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.

Investigation of a suspected outbreak of carbapenem-resistant Klebsiella pneumonia infection / 上海预防医学

ObjectiveTo investigate a suspected outbreak of healthcare-associated infection （HAI） caused by carbapenem-resistant Klebsiella pneumonia （CRKP） in a secondary grade-A hospital， analyze the infection source and transmission route， and put forward corresponding preventive and control measures. MethodsEpidemiological investigation was conducted on 5 patients with CRKP infection in department of neurosurgery during December 23‒30， 2021. Specimens were collected with the environmental microbiology monitoring procedure. CRKP isolated from the environmental samples were analyzed by multilocus sequence typing （MLST） method. Comprehensive measures were taken to control the CRKP infection. ResultsThe 5 infected patients were located in 3 rooms， and all were diagnosed as HAI. The antimicrobial susceptibility testing results from the specimens of 3 CRKP infected patients were the same. Through environmental microbiology monitoring， CRKP strains were detected from the faucet handle and sink specimens in 3 rooms. The results of MLST analysis showed that the faucet handle and sink specimens in room 2 and 3 were ST11 type. The environmental specimen in room 1 was ST23 type. The suspected outbreak was effectively controlled after comprehensive interventions. ConclusionHAI suspected outbreak might be caused by the environmental contamination from the pathogens of CRKP-infected patients as well as the contaminated hands of medical staff and accompanying family members. Strengthening the publicity， education and management of medical staff and accompanying staff， early identification of infection outbreaks， and timely comprehensive control measures are the keys to controlling multidrug-resistant nosocomial infection outbreaks.

An epidemiological investigation of an border-imported case with Plasmodium vivax malaria / 预防医学

Abstract@#On March 12, 2022, a case with Plasmodium vivax malaria was reported in the First Hospital of Jiaxing City. The case sought healthcare services due to persist, sharp distending pain of the brain and fever on February 25, 2022, and the symptoms showed no improvements following symptomatic treatment. Microscopy identified malaria parasites on March 12, and the case was definitively diagnosed as P. vivax malaria on March 13. The case was discharged from hospital on March 16 and relapsed on June 15. The case was a veteran from the China-Myanmar border, where malaria is highly prevalent, and had no history of travel after returning to Jiaxing City on October 2021. Based on epidemiological history and laboratory tests, the case was diagnosed as a cross-border mosquito-borne imported case of P. vivax malaria. The case was given treatment with mosquito vector isolation, and the case's family members, neighbors and colleagues were all tested negative for malaria parasites. There was no Anopheles sinensis detected in the case' residence; however, Anopheles was detected in the neighboring areas, indicating a risk of re-establishment. Returners from high-risk regions including borders and labor exporters are recommended to be included in malaria surveillance, and the sensitivity of malaria surveillance requires to be maintained and the diagnostic and treatment capability of malaria requires to be improved in medical institutions.
