Profile and characteristics of violence against older adults during the COVID-19 pandemic / Perfil e características da violência contra a pessoa idosa durante a pandemia COVID-19 / Perfil y características de la violencia contra los adultos mayores durante la pandemia de COVID-19

Abstract Objective: to identify the sociodemographic profile and the characteristics of interpersonal violence against older adults during the first year of the COVID-19 pandemic in a capital city from the Brazilian Southeast region. Method: a descriptive and exploratory research study with a cross-sectional design based on the notifications of suspected or confirmed cases of violence against older adults between March 2020 and March 2021. A univariate statistical analysis and Fisher's exact test (p<0.05) were performed. Results: a total of 2,681 notifications were recorded during the period. The main victims were individuals aged between 60 and 64 years old, female, white-skinned and with low schooling levels. The instances of violence were more frequent in the victims' homes. Physical and psychological violence predominated, through physical force/beatings and threats, respectively. Most of the aggressors were male, younger than the victims and generally their children or intimate partners. The aggressions were perpetrated more than once and were driven by generational conflicts. There was low referral to entities for the protection of older adults. Conclusion: the sociodemographic profile found evidences vulnerable victims, subjected to many types of violence, and at a potential risk against their overall health.

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.

Risk of bias in dentistry-related randomized controlled trials in spanish language journals

Objectives: To assess the risk of bias (RoB) of randomized controlled trials (RCTs) published in dental journals in the Spanish language. Methods: A systematic retrospective survey was conducted of all RCTs published from 1980 to 2019 in dentistry Spanish and Latin American journals. We extracted data and performed RoB assessments using the Cochrane Risk of Bias tool. Results: 292 RCTs published in 51 journals were included. The best-rated domains were incomplete outcome data, selective reporting, and other biases. The domains assessed with higher proportions of an unclear or high risk of bias were sequence generation, allocation concealment, and blinding of outcome assessment. There is a low proportion of RCTs published in Spanish language journals. However, the number has been increasing over the years, and the low risk of bias assessment rates across domains show an increasing trend. Conclusions: A low percentage of Spanish-language dental journals issue RCTs. Our assessment of these RCTs' RoB suggests higher difficulties in the design and conduction phase than in the posterior reporting stage.

As práticas profissionais realizadas em situações de maus-tratos infantis: uma revisão integrativa / Professional practices in situations of child abuse: an integrative review

Resumo A violência infantil é um problema que afeta crianças no mundo todo. O presente estudo objetiva identificar e analisar os principais resultados apresentados em artigos publicados no Brasil sobre as práticas profissionais desenvolvidas em situações de maus-tratos infantis. Para tanto, realizou-se uma revisão integrativa da literatura, com buscas nas bases de dados Google Acadêmico, no SciELO Brasil, nos Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior do Ministério da Educação (CAPES/MEC), no MEDLARS ONLINE (Medline), na Biblioteca Virtual em Saúde (BVS Saúde) e nos Periódicos Eletrônicos em Psicologia (Pepsic), abrangendo publicações de 2017 a 2022. Após a leitura dos títulos e resumos, 24 artigos foram selecionados para a análise. Os resultados apontam a dificuldade na proteção integral da criança devido à deficiência na formação do profissional, que influencia na identificação e notificação do abuso infantil. O presente estudo revela o lugar que os maus-tratos infantis ocupam na formação dos profissionais e subsidia pesquisas futuras sobre práticas profissionais para o enfrentamento da violência infantil.

Abstract Child abuse is a problem that affects children all over the world. The present study therefore aimed to identify and analyze the main findings relating to professional practices for dealing with situations of child maltreatment in articles published in Brazil. To this end, we conducted an integrative literature review of articles published between 2017 and 2022 based on searches of the following databases: Google Scholar, SciELO Brasil, the periodicals database of the Agency for the Improvement of Higher Education Personnel (CAPES), MEDLINE, the Virtual Health Library, and Electronic Journals in Psychology (PePSIC). A total of 24 publications were selected for the review after screening the titles and abstracts. The findings reveal several challenges to ensuring the protection of children caused by shortcomings in professional training, which have a negative influence on the identification and reporting of child maltreatment. The present study reveals the lack of priority given to the issue of child maltreatment in professional training and provides important inputs to inform future research on professional practices for dealing with child violence.

A study on the knowledge, attitude, and practice on adverse drug reactions and pharmacovigilance among nursing staff

Background: Lack of knowledge of pharmacovigilance and underreporting of adverse drug reaction (ADR) are worldwide problems of big concern. Gross underreporting of ADR in India led to increased hospital admissions, increase in length of hospital stay, and increase in healthcare cost burden. Aims and Objectives: This study was planned to assess knowledge, attitude, and practice on ADR and pharmacovigilance among nursing staff in Gandhi Medical College and Associated Hospitals, Bhopal Madhya Pradesh. Materials and Methods: A questionnaire-based, cross-sectional, and observational study was conducted among nursing staff in a tertiary care Centre. Data were collected in the form of a validated questionnaire comprised of 17 questions regarding knowledge, attitude, and practice of nursing staff toward ADR and Pharmacovigilance. Data were analysis by descriptive statistics and result was computed. Results: Around 33% of respondents were aware of Pharmacovigilance program of India and 99% of them had knowledge about main objective of pharmacovigilance. Out of total filled questionnaire received, only 12% nurses practiced reporting ADR. The major factor discouraging participants from reporting ADR was lack of time to report. The majority of nursing staff had a positive attitude toward awareness of pharmacovigilance and ADR reporting. Conclusion: Our study has shown that there is lack of correct knowledge regarding ADR reporting and pharmacovigilance among staff nurses. Although, the attitude toward ADR reporting was adequate, the actual practice of ADR reporting is unsatisfactory. Hence, it is essential to train staff nurses regarding pharmacovigilance and ADR reporting

Knowledge, attitudes, and experiences of a group of turkish dentists regarding child abuse / Conocimientos, actitudes y experiencias de un grupo de dentistas turcos en relación con el abuso infantil

Child abuse is a universal problem with critical lifelong effects. This study aimed to evaluate knowledge, attitudes, experiences of dentists regarding child abuse and to increase relevant awareness of them. A self-administered questionnaire with 48 questions about dentists' personal and educational information and their level of knowledge, attitudes, experiences on child abuse was implemented. Out of targeted 305 participants, 183 (60.0%) returned completely filled out questionnaires. Majority of participants knew signs and symptoms of child abuse. Of the participants, more than half were well-informed on what to do, however, one quarter had no knowledge about where to report in case of child abuse. In identifying child abuse, 39.3% of the participants found themselves inadequate. The most commonly stated reason for low rate of reporting was hesitancy to identify the case as abuse, and all participants needed more training. Only 12 (6.6%) participants suspected a case of child abuse. Dentists who had children and were long-time experienced and generalist did not have sufficient knowledge about legal obligations, signs and symptoms of child abuse (p<0.05). Arrangements and training programs to increase knowledge, awareness, and responsibility levels of dentists about child abuse appear to be a critically important topic.

El abuso infantil es un problema universal con efectos críticos de por vida. Este estudio tuvo como objetivo evaluar el conocimiento, las actitudes y las experiencias de los dentistas con respecto el abuso infantil y aumentar la conciencia relevante sobre ellos. Se implementó un cuestionario autoadministrado con 48 preguntas sobre información personal y educativa de los odontólogos y su nivel de conocimientos, actitudes, experiencias sobre el abuso infantil. De los 305 participantes seleccionados, 183 (60.0%) devolvieron los cuestionarios completos. La mayoría de los participantes conocían los signos y síntomas del abuso infantil. De los participantes, más de la mitad estaban bien informados sobre qué hacer, sin embargo, una cuarta parte no sabía dónde denunciar en caso de abuso infantil. Al identificar el abuso infantil, el 39.3% de los participantes se encontraron inadecuados. La razón más común para la baja tasa de informes fue la vacilación para identificar el caso como abuso, y todos los participantes necesitaban más capacitación. Solo 12 (6.6%) participantes sospecharon un caso de abuso infantil. Los odontólogos que tenían hijos y eran de larga experiencia y generalistas no tenían suficiente conocimiento sobre las obligaciones legales, signos y síntomas de abuso infantil (p<0,05). Los arreglos y los programas de capacitación para aumentar los niveles de conocimiento, conciencia y responsabilidad de los dentistas sobre el abuso infantil parecen ser un tema de importancia crítica.

Reporting of conflict of interests, source of funding, and ethics committee approval in randomized trials of three clinical specialties published in Spanish language

Background: Confidence in the results reported by randomized clinical trials (RCTs) depends mainly on the internal validity of the trial and its conduct, but also on other aspects related to health research such as the complete reporting of conflicts of interest (COI), funding sources and approval by ethics committees. Bias in the study results may arise from any one of these elements. Prior studies have explored the reporting of these items in the medical literature, but there are no reports on RCTs published in Spanish and Latin American journals. This study aimed to evaluate the reporting of COIs, funding sources, and approval by ethics committees of RCTs published in Spanish and Latin American journals in dentistry, geriatrics and neurology. Methods: We did a systematic retrospective survey of all RCTs published from 1990 to 2018 in dentistry, neurology, and geriatrics journals published in Spain and Latin America and included in the BADERI database (Iberoamerican journals and trials database by its initials in Spanish). We completed with hand searching. We included RCTs with a recoverable full text published between 1990 and 2018. We extracted data on sources of funding, COI statements, and ethics reviews. The extraction of these items in the RCTs included was done independently by two pairs of reviewers and in parallel for each article, with a third independent reviewer resolving discrepancies. We analysed compliance for each item. Results: We identified RCTs in 69 journals from Spain and Latin American countries. Dentistry accounted for 75% (n = 52) of the journals, neurology 20.6% (n = 14), and geriatrics 4.4% (n = 3). Of the total number of RCTs included in this study (n = 392), only 102 (26%) reported the presence or absence of a COI, 103 (26%) studies reported funding, and 43 (36%) included the ethics committee approval. Conclusions: RCTs published in the Spanish language in dentistry, neurology, and geriatrics had poor compliance with the reporting of a COI, source of funding, and ethics committee approval. Future research should evaluate the accuracy and completeness of COI statements and their relationship to the funding source and direction of the results.

Leishmaniasis cutánea en Colombia: una mirada epidemiológica / Cutaneous leishmaniasis in Colombia: an epidemiological overview

La leishmaniasis resulta una enfermedad infectocontagiosa causada por un protozoo del género Leishmania. Esta constituye un problema de salud importante para diversas regiones de América Latina. El aislamiento social impuesta a raíz de la pandemia de COVID-19 favoreció que disminuyera la incidencia de esta entidad, pero las actividades sociales de la normalidad se retomaron paulatinamente, imponiéndose que se retomen las medidas de seguimiento y control correspondientes.

Leishmaniasis is an infectious disease caused by a protozoan of the genus Leishmania. Leishma-niasis constitutes a significant health problem for various regions of Latin America. The social isolation imposed because of the COVID-19 pandemic favored a decrease in the incidence of this entity. However, regular social activities were gradually resumed, imposing the correspon-ding monitoring and control measures.

Perceptions of incidents and incident reporting among staff nurses in a tertiary Philippine hospital

INTRODUCTION@#The number of injuries and expenses from unsafe delivery of health care has heeded the call for a greater patient safety advocacy. The development of an effective reporting system contributes towards this cause. The study aimed to explore the perceptions of nurses regarding critical incidents and investigate the factors affecting their decision to report a certain event.@*METHODS@#Focus group discussions including 28 nurses working in the service wards of a tertiary hospital, and the data gathered were analyzed using descriptive qualitative approach.@*RESULTS@#Three key themes emerged from the discussions: (1) perceptions of an incident, (2) attitudes, norms, and culture of incident reporting in the workplace, and (3) perceptions and suggestions for management actions and improving the reporting system. The study showed that various factors tend to interplay in the identification of an incident as well as the consideration to perform the behavior.@*DISCUSSION@#The primary practice and education implications focus on changing the workplace culture and proper orientation of the staff, while further research regarding the role of reporting, and appropriate analysis of error reporting among other health care professionals would be recommended.

Diagnostic value of CEM and MRI in differentiating benign and malignant breast lesions based on the 2013 BI-RADS lexicon and the supplement on CEM / 中华放射学杂志

Objective:To explore the diagnostic value of contrast-enhanced mammography (CEM) and MRI in differentiating benign and malignant breast lesions based on the 2013 breast imaging reporting and data system (BI-RADS) lexicon and the supplement on CEM.Methods:The clinical and imaging data of 83 patients with breast lesions from March 2019 to April 2022 in the Third Affiliated Hospital of Soochow University were retrospectively analyzed. Totally 100 breast lesions from 83 female patients aged 28 to 78 (49±14) years, were divided into benign lesions (50 lesions) and malignant lesions (50 lesions) according to the pathological results. The t-test, χ 2 test and Fisher′s exact test were used to compare the differences of clinical and imaging features between benign and malignant lesions, and these imaging features which had statistical differences were established CEM and MRI models by multivariate logistic regression analysis respectively. The receiver operating characteristic curves and the area under the curve (AUC) were used to assess the diagnostic efficacy of two models in differentiating benign and malignant breast lesions. Using the DeLong test compared the AUC. Results:Multivariate logistic regression analysis showed that associated features (OR=9.075,95%CI 1.430-57.570, P=0.019), lesion conspicuity (OR=6.180,95%CI 2.608-14.646, P<0.001), mass margin (OR=2.193,95%CI 1.405-3.422, P=0.001) and calcification distribution (OR=2.147,95%CI 1.157-3.986, P=0.015) were independent predictors of differentiating benign and malignant breast lesions in CEM, and then the predictive model of CEM was constructed. Time-signal intensity curve (OR=9.230, 95%CI 3.178-26.805, P<0.001), associated features (OR=5.289,95%CI 1.343-20.831, P=0.017) and mass margin (OR=2.192,95%CI 1.336-3.597, P=0.002) were independent predictors of differentiating benign and malignant breast lesions in MRI, and the predictive model of MRI was constructed. The AUC of CEM and MRI models for differentiating benign and malignant breast lesions were 0.947 and 0.930 respectively, and two models were no significant difference ( Z=0.68, P=0.494). Conclusion:The diagnostic efficacy of CEM and MRI in differentiating benign and malignant breast lesions is comparable based on the 2013 BI-RADS lexicon and the supplement on CEM.

MRI-based neck imaging reporting and data systems in diagnosis of extracavity local recurrent nasopharyngeal carcinoma and posttreatment changes / 中华放射学杂志

Objective:To evaluate the diagnostic value of neck imaging reporting and data systems (NI-RADS) based on MRI in extracavity local recurrent nasopharyngeal carcinoma (ELRNPC) and posttreatment changes (PTC).Methods:From April 2015 to September 2020, 33 cases of ELRNPC and 37 cases of PTC confirmed by pathology or follow-up were retrospectively enrolled at Zhongshan City People′s Hospital. Two radiologists independently evaluated the conventional MRI findings using NI-RADS criteria in the first step, then evaluated with conventional MRI and diffusion weighted imaging (DWI) sequences in the second step. All images were re-evaluated by one senior radiologist in the same steps after three months. Inter- and intra-reader agreements were assessed with Cohen′s Kappa test. Receiver operating characteristic curves were generated to assess the diagnostic values of NI-RADS categories between ELRNPC and PTC. The area under the curve (AUC) was compared by Delong test.Results:Inter- and intra-reader agreements of Kappa value were 0.742 and 0.909 for conventional MRI and 0.807 and 0.934 for conventional MRI with DWI. In the differential diagnosis of ELRNPC and PTC, the AUC, sensitivity, and specificity of NI-RADS categories based on conventional MRI were 0.932 (95%CI 0.846-0.978), 87.9% (95%CI 71.8%-96.6%), 94.6% (95%CI 81.8%-99.3%), and of NI-RADS based on conventional MRI with DWI were 0.991 (95%CI 0.933-1.000), 93.9% (95%CI 79.8%-99.3%), 97.3% (95%CI 85.8%-99.9%), respectively. There was a statistical difference between the AUCs of the two categories ( Z=2.20, P=0.028). Conclusions:For both the NI-RADS based on MRI with or without DWI, the differential diagnostic value of ELRNPC and PTC is excellent, while the consistency and diagnostic performance are more substantial when combined with DWI.

The consistency and application value of MRI-based ovarian-adnexal reporting and data system in the diagnosis of ovarian adnexal masses / 中华放射学杂志

Objective:To explore the consistency of MRI-based ovarian-adnexal report and data system (O-RADS) score and its diagnostic value for ovarian adnexal masses.Methods:The MRI data of 309 patients with ovarian adnexal masses confirmed by pathology were retrospectively collected from January 2017 to August 2021 in the Second Affiliated Hospital of Soochow University, including 327 lesions consisted of 250 benign lesions, 21 borderline lesions, and 56 malignant lesions confirmed by pathology. Borderline and malignant lesions were classified into the malignant group ( n=77) and benign lesions were classified as benign group ( n=250). Two radiologists scored all lesions according to the MRI-based O-RADS, and scored again after 6 months. The proportion of borderline/malignant lesions in each MRI-based O-RADS score was calculated. The weighted Kappa test was used to assess the intra-reader and inter-reader consistency of the image interpretation results. The receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic efficacy of MRI-based O-RADS classification for distinguishing benign and malignant ovarian adnexal masses. Results:The weighted Kappa value of the MRI-based O-RADS score between the two radiologists was 0.810 (95%CI 0.764-0.855), and the weighted Kappa values of the two radiologists′ scores at different times were 0.848 (95%CI 0.806-0.889) and 0.875 (95%CI 0.835-0.914), respectively. The borderline/malignant lesions accounted for 0/16, 0.8% (1/127), 10.1% (10/99), 76.0% (57/75), 9/10 and 0/17, 0 (0/122), 8.0% (8/100), 76.2% (48/63), and 84.0% (21/25) of the lesions in the two radiologists based on the MRI O-RADS score of 1, 2, 3, 4, and 5, respectively. When adopting O-RADS score>3 as a cut-off value, the area under the ROC curve of the two radiologists for distinguishing benign and malignant ovarian adnexal masses was 0.928 (95%CI 0.895-0.954) and 0.942 (95%CI 0.911-0.965), respectively. The sensitivity was 0.857 and 0.896, the specificity was 0.924 and 0.924, and the accuracy was 0.908 and 0.917 respectively.Conclusion:The MRI-based O-RADS yields high diagnostic efficiency in the evaluation of benign and malignant ovarian adnexal masses, and the intra-reader and inter-reader consistency of the image interpretation is strong.

The value of radiomics based on contrast-enhanced spectral mammography of internal and peripheral regions combined with clinical factors in predicting benign and malignant breast lesions of breast imaging reporting and data system category 4 / 中华放射学杂志

Objective:To evaluate the value of radiomics based on contrast-enhanced spectral mammography (CESM) of internal and peripheral regions combined with clinical factors in predicting benign and malignant breast lesions of breast imaging reporting and data system category 4 (BI-RADS 4).Methods:A retrospective analysis was performed on the clinical and imaging data of patients with breast lesions who were treated in Yantai Yuhuangding Hospital (Center 1) Affiliated to Qingdao University from July 2017 to July 2020 and in Fudan University Cancer Hospital (Center 2) from June 2019 to July 2020. Center 1 included 835 patients, all female, aged 17-80 (49±12) years, divided into training set (667 cases) and test set (168 cases) according to the "train-test-split" function in Python software at a ratio of 8∶2; and 49 patients were included from Center 2 as external validation set, all female, aged 34-70 (51±8) years. The radiomics features were extracted from the intralesional region (ITR), the perilesional regions of 5, 10 mm (PTR 5 mm, PTR10 mm) and the intra-and perilesional regions of 5, 10 mm (IPTR 5 mm, IPTR 10 mm) and were selected by variance filtering, SelectKBest algorithm, and least absolute shrinkage and selection operator. Then five radiomics signatures were constructed including ITR signature, PTR 5 mm signature, PTR 10 mm signature, IPTR 5 mm signature, IPTR 10 mm signature. In the training set, univariable and multivariable logistic regressions were used to construct nomograms by selecting radiomics signatures and clinical factors with significant difference between benign and malignant BI-RADS type 4 breast lesions. The efficacy of nomogram in predicting benign and malignant BI-RADS 4 breast lesions was evaluated by the receiver operating characteristic curve and area under the curve (AUC). Decision curve and calibration curve were used to evaluate the net benefit and calibration capability of the nomogram.Results:The nomogram included ITR signature, PTR 5 mm signature, PTR 10 mm signature, IPTR 5 mm signature, age, and BI-RADS category 4 subclassification for differentiating malignant and benign BI-RADS category 4 breast lesions and obtained AUCs of 0.94, 0.92, and 0.95 in the training set, test set, and external validation set, respectively. The calibration curve showed good agreement between the predicted probabilities and actual results and the decision curve indicated a good net benefit of the nomogram for predicting malignant BI-RADS 4 lesions in the training set, test set, and external validation set.Conclusion:The nomogram constructed from the radiomics features of the internal and surrounding regions of CESM breast lesions combined with clinical factors is attributed to differentiate benign from malignant BI-RADS category 4 breast lesions.

Objective:To assess the value of S-Detect and contrast-enhanced ultrasound (CEUS) in the differential diagnosis of Breast Imaging Reporting and Data System(BI-RADS) 4 breast lesions.Methods:A total of 104 breast lesions in 100 patients diagnosed as BI-RADS category 4 by conventional ultrasound were prospectively enrolled, and all of them were received S-Detect and CEUS examination at the same time. Taking pathology as the gold standard, ROC curve was constructed to compare the diagnostic efficacy of conventional ultrasound, S-Detect, CEUS and their combination.Results:Among the 104 BI-RADS category 4 breast lesions, 63 were benign and 41 were malignant. The sensitivities of conventional ultrasound, S-Detect, CEUS and S-Detect combined with CEUS were 73.17%, 87.80%, 87.80%, 90.24%; the specificities were 57.14%, 60.32%, 68.25%, 77.78%; the positive predictive values were 52.63%, 59.02%, 64.29% and 72.55%; the negative predictive values were 76.60%, 88.37%, 89.59% and 92.45%; the accuracies were 63.46%, 71.15%, 75.96% and 82.69%; and the areas under the ROC curve (AUC) were 0.652, 0.741, 0.780 and 0.840. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of S-Detect and CEUS diagnosis were improved compared with conventional ultrasound. The AUC of combined diagnosis was higher than that of S-Detect, CEUS alone, and the differences were statistically significant(all P<0.05). The AUC of CEUS was higher than that of conventional ultrasound, and the difference was statistically significant ( P<0.05). There were no significant differences in AUC between any two of other groups (all P>0.05). Conclusions:The combined application of S-Detect and CEUS could achieve complementary advantages, which is of great significance for the differential diagnosis of benign and malignant in BI-RADS 4 breast lesions.

Correlation analysis of contrast-enhanced ultrasound Liver Imaging Reporting and Data System classification with hepatocellular carcinoma differentiation and Ki-67 index / 中华超声影像学杂志

Objective:To investigate the correlation of hepatocellular carcinoma (HCC) classified by contrast-enhanced ultrasound (CEUS) Liver Imaging Data and Report System (LI-RADS) with differentiation degree and Ki-67 index.Methods:A multicenter, retrospective study was conducted.The clinical and CEUS imaging data of 208 patients with 208 HCC lesions from December 2017 to December 2020 in China CEUS database were included and analyzed. According to the CEUS LI-RADS version 2017 proposed by the American College of Radiology, the HCC was classified. The diagnosis and pathological information of all lesions were confirmed by pathology. The differentiation degree of HCC and the distribution of Ki-67 index in different LI-RADS categories were evaluated, and their correlation was analyzed.Results:The degree of differentiation and Ki-67 index among HCC of different CEUS LI-RADS were statistically significant ( P<0.001, P=0.009). LI-RADS M HCC was more likely to be poorly differentiated and showed a higher Ki-67 index. The category of LI-RADS was positively correlated with the degree of tumor differentiation (tau-b=-0.250, P<0.001) and the Ki-67 index (tau-b=0.178, P=0.002), that is, the higher the category of LI-RADS, the lower differentiation degree and the higher the Ki-67. Conclusions:The CEUS LI-RADS classification of HCC is correlating with the degree of differentiation and Ki-67 index.

ObjectiveTo systematically evaluate the safety of interferon β-1a for treatment of corona virus disease 2019 （COVID-19）， and to provide references for interferon β-1a's clinical application. MethodsThis study was conducted with the database from US Food and Drug Administration adverse event reporting system （FAERS） from January 1， 2015 to March 31， 2021. Information component （IC） and reporting odds ratio （ROR） methods were applied for signal mining. ResultsA total of 463 700 records of COVID-19 were selected for analysis， and 45 positive drug adverse event signals were detected. Headache （IC025=1.09， ROR025=2.28）， pyrexia （IC025=0.51， ROR025=1.51） and multiple sclerosis relapse （IC025=3.67， ROR025=14.71） were positive adverse events with higher frequency. Autoimmune disorder （IC025=4.42， ROR025=24.03）， streptococcal infection （IC025=4.12， ROR025=19.82）， and multiple sclerosis relapse （IC025=3.67， ROR025=14.71） were positive adverse events. Acute lung injury， cardio-respiratory arrest and metabolic acidosis were associated with a higher proportion and frequency of death. ConclusionThere are certain safety issues with interferon β-1a in the treatment of COVID-19， and some adverse events with high frequency and high death rate deserve further attention by medical staffs.

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.

Evaluation on quality of internet-based reporting of COVID-19 in Ningxia, 2020-2021 / 中国热带医学

@#Abstract: Objective　To find out the existing problems and provide reference for further improving the quality of report information by analyzing the report cards of COVID-19 and the positive report cards of primary screening reported in Ningxia. Methods　All COVID-19 case cards from 2020 to 2021 and initial screening positive cards were derived from the Chinese Information System for Disease Control and Prevention according to final review date. The timeliness of case reporting, timeliness of case review, completeness and accuracy of the case cards were analyzed. Results　In Ningxia, the first case of COVID-19 was reported on January 20, 2020, and as of December 31, 2021, 122 confirmed cases and 4 symptomatic infected cases were reported. In 2021, the timely reporting rate of COVID-19 was 98.00%, which increased by 8.24% compared with 2020 (90.54%). Compared with 2020, the average time limit for diagnosis to reporting of COVID-19 in 2021 was shortened by 83.12%; in 2021, the timely review rate of COVID-19 was 100.00%, which increased by 13.84% compared with 2020 (87.84%). Compared with 2020, the time from reporting to final review was shortened by 98.91%. In 2021, the timely rate of positive reports in COVID-19 in Ningxia was 90.00%, among which the timely rate of reports by county (district) nucleic acid detection institutions was the highest (92.31%), followed by municipal (91.67%) and autonomous region (81.82%). Conclusions　At the beginning of the epidemic in 2020, the timeliness of COVID-19 in Ningxia was poor, and through the implementation of measures such as technical training, supervision and inspection to continuously optimize the staffing of medical institutions and disease control institutions, the timeliness of reporting COVID-19 in Ningxia in 2021 was substantially improved, but there were still some weak links. In the future work, technical guidance and training should be carried out for weak links, and efforts should be made to improve the quality of reports.

Analysis of Taijiquan-related clinical trial registration characteristics and reporting quality / 国际中医中药杂志

Objective:To analyze the registration characteristics and reporting quality of Taijiquan-related clinical trials.Methods:A database search of the China Clinical Trials Registry (ChiCTR) and ClinicalTrials.gov was performed by computer to collect basic information, study content, interventions, and other registration information of Taijiquan-related clinical trials from inception to June 30, 2022. The WHO TRDS was used to evaluate the registration quality of clinical trials.Results:Totally 381 Taijiquan-related clinical trials were incorporated, of which 241 (63.25%) were prospective registration and 140 (36.75%) were retrospective registration. The quantity of Taijiquan-related clinical trial registrations generally showed an increasing trend, reaching a peak in 2020 (14.70%). The number of clinical trials registered in Shanghai accounted for the most (9.97%). The largest contributor to the registered trials was Fujian University of Traditional Chinese Medicine (4.46%). 55.12% of registered studies were funded by hospitals and universities. The registered studies were most focused on cognitive impairment. 74.54% of the studies adopted randomized parallel controls, and the sample size was mainly between 20 and 200 (80.31%), and the age of the subjects was concentrated above 39 years (53.28%). The average report completion rate of WHO TRDS items was 86.90%.Conclusions:Presently, the development trend of clinical trials related to Taijiquan is relatively promising. However, imbalances exist in some aspects, for instance distribution of registration areas and institutions, funding allocation, and population of subjects. The description of some registration items is missing or not comprehensive, so corresponding measures are required to improve the quality of clinical trial design and to optimize registration details.
