ABSTRACT

RESUMEN Objetivos. Evaluar la exactitud de gota gruesa (GG) frente a la reacción en cadena de la polimerasa (PCR) cuantitativa para la malaria asociada al embarazo (MAE). Materiales y métodos. Se realizó una revisión sistemática de pruebas diagnósticas en nueve bases de datos. Se evaluó la calidad metodológica con QUADAS. Se estimó sensibilidad, especificidad, cociente de probabilidad positivo (CPP) y negativo (CPN), razón de odds diagnóstica (ORD) y área bajo la curva ROC. Se determinó la heterogeneidad con el estadístico Q de Der Simonian-Laird y la incertidumbre con el porcentaje de peso de cada estudio sobre el resultado global. Resultados. Se incluyeron diez estudios con 5691 gestantes, 1415 placentas y 84 neonatos. En los estudios con nPCR (PCR anidada) y qPCR (PCR cuantitativa) como estándar, los resultados de exactitud diagnóstica fueron estadísticamente similares, con sensibilidad muy baja (50 y 54%, respectivamente), alta especificidad (99% en ambos casos), alto CPP y deficiente CPN. Usando nPCR la OR diagnóstica fue 162 (IC95%=66-401) y el área bajo la curva ROC fue 95%, mientras que con qPCR fueron 231 (IC95%=27-1951) y 78%, respectivamente. Conclusiones. Mediante un protocolo exhaustivo se demostró el bajo desarrollo de investigaciones sobre la exactitud diagnóstica de la GG en MAE. Se demostró que la microscopía tiene un desempeño deficiente para el diagnóstico de infecciones asintomáticas o de baja parasitemia, lo que afianza la importancia de implementar otro tipo de técnicas en el seguimiento y control de las infecciones por malaria en las gestantes, con el fin de lograr el control y posible eliminación de la MAE.


ABSTRACT Objective. To evaluate the accuracy of thick smear (TS) versus quantitative polymerase chain reaction (PCR) for pregnancy-associated malaria (PAM). Materials and methods. We carried out a systematic review of diagnostic tests in nine databases. Methodological quality was evaluated with QUADAS. Sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and area under the ROC curve were estimated. Heterogeneity was determined with the Der Simonian-Laird Q method and uncertainty with the weighted percentage of each study on the overall result. Results. We included 10 studies with 5691 pregnant women, 1415 placentas and 84 neonates. In the studies with nested PCR (nPCR) and quantitative PCR (qPCR) as the standard, the diagnostic accuracy results were statistically similar, with very low sensitivity (50 and 54%, respectively), high specificity (99% in both cases), high PLR and poor NLR. When nPCR was used, the DOR was 162 (95%CI=66-401) and the area under the ROC curve was 95%, while with qPCR it was 231 (95%CI=27-1951) and 78%, respectively. Conclusions. We demonstrated that research on the diagnostic accuracy of TS in PAM is limited. Microscopy showed poor performance in the diagnosis of asymptomatic or low parasitemia infections, which reinforces the importance of implementing other types of techniques for the follow-up and control of malaria infections in pregnant women, in order to achieve the control and possible elimination of PAM.

ABSTRACT

Resumen. Si bien la investigación sobre la metacognición y los estilos cognitivos es sólida para cualquier campo solo, pocas investigaciones han abordado los dos juntos. Además, ningún estudio hasta la fecha ha examinado objetivos más específicos relacionados con aspectos específicos de la metacognición, como la habilidad de monitoreo y su relación con el estilo cognitivo. Por lo tanto, el presente estudio investigó medidas de confianza, rendimiento y precisión para tres tipos de juicios metacognitivos (predicción, concurrente y postdicción) y tres tipos diferentes de preguntas metacognitivas: preguntas sobre la tarea, preguntas sobre uno mismo y preguntas en diferentes momentos (antes, durante y después) y cómo se relacionan con el estilo cognitivo (dependiente del campo, intermedio, independiente del campo) en una muestra de 57 estudiantes universitarios colombianos. Los resultados revelaron que había diferencias en la precisión y el sesgo del monitoreo metacognitivo en función del estilo cognitivo, y que estos hallazgos fueron similares entre los diferentes momentos y entre los juicios metacognitivos. Con respecto al estilo cognitivo, aquellos con un estilo cognitivo intermedio o independiente del campo informaron una mayor precisión de monitoreo y menos sesgo que las personas con un estilo dependiente del campo. Se discuten las implicaciones para la investigación, la teoría y la práctica.


Abstract. While research on metacognition and cognitive styles is robust for either field alone, few studies have broached the two together. In addition, no studies to date have examined finer-grained objectives related to specific aspects of metacognition such as monitoring skill and its relation to cognitive style. Thus, the present study investigated confidence, performance, and accuracy measures for three types of metacognitive judgments (prediction, concurrent and postdiction) and three different types of metacognitive questions-questions about the task, questions about the self, and questions at different moments (before, during, and after)-and how these are related to cognitive style (field dependent, intermediate, field independent) in a sample of 57 Colombian university students. Results revealed that there were differences in metacognitive monitoring accuracy and bias as a function of cognitive style, and that these findings were similar both between different moments and across metacognitive judgments. Regarding cognitive style, those with an intermediate or field independent cognitive style reported greater monitoring accuracy and less bias than individuals with a field dependent style. Implications for research, theory, and practice are discussed.

ABSTRACT

Introducción: la información sobre las causas de muerte es de gran importancia tanto para los países como para las instituciones sanitarias, en la medida en que contribuye a la evaluación y el seguimiento del estado de salud de la población y a la planificación de intervenciones sanitarias. El objetivo del estudio fue evaluar la proporción de causas de muerte mal definidas e imprecisas y su relación con el día de la semana y período lectivo de médicos residentes en el Hospital Italiano de Buenos Aires (HIBA) durante 2020. Métodos: se realizó un estudio analítico de corte transversal a partir de certificados médicos de defunción de pacientes fallecidos en el ámbito intrahospitalario, evaluando las causas de muerte mal definidas (términos médicos que no aportan información desde el punto de vista clínico y epidemiológico) y las imprecisas (no resultan lo suficientemente específicas como para identificar entidades nosológicas que permitan establecer acciones de prevención y control). Resultados: se analizaron 1030 certificados de defunción, con una proporción de certificados con causa básica de muerte mal definida del 2,3% (n = 24), mientras que en el 17,4% (n = 180) fue imprecisa. No se hallaron diferencias entre la proporción de causas básicas mal definidas y las imprecisas según el día de la semana o período lectivo. Al extender el análisis a todas las causas (básicas, mediatas e inmediatas), la proporción de causas mal definidas fue del 1,6% (n = 40) y la de imprecisas del 51% (n = 1212). Conclusiones: los resultados definen al HIBA como un centro de mediana calidad estadística en el registro de causas de muerte. Se concluye que es necesario mejorarla, para lo que resulta de interés la creación de un plan de capacitación y entrenamiento de los médicos en el grado y el posgrado. (AU)


Introduction: information on causes of death is of great importance both for countries and for health institutions, as it contributes to the evaluation and monitoring of the health status of the population and to the planning of health interventions. The purpose of this study was to evaluate the proportion of ill-defined and imprecise causes of death and its relationship with the day of the week and academic calendar during 2020 at the Hospital Italiano de Buenos Aires. Methods: a cross-sectional study was carried out from data recorded in the death certificates of patients who died in the intrahospital setting, evaluating ill-defined causes of death (medical terms that do not provide clinical or epidemiological information) and imprecise ones (not specific enough to identify nosological entities susceptible to prevention or control). Results: 1030 death certificates were analyzed. The proportion of certificates with ill-defined underlying causes of death was 2.3% (n=24), while 17.4% (n=180) was imprecise. No significant differences were found between the ill-defined and imprecise underlying causes of death and the day of the week and academic calendar. When extending the analysis to all causes (underlying, intermediate, and immediate) the percentage of ill-defined causes was 1.6% (n=40) and 51% (n=1212) was imprecise. Conclusions: results define our hospital as of medium statistical quality on medical death certification. It is concluded that it is necessary to improve the quality of the registry, for which the creation of a training plan for undergraduate and graduate physicians is of interest. (AU)

ABSTRACT

Objective: The present meta-analysis was conducted to determine the diagnostic accuracy of the bipolarity index (BI) and Rapid Mode Screener (RMS) as compared with the Bipolar Spectrum Diagnostic Scale (BSDS), the Hypomania Checklist (HCL-32), and the Mood Disorder Questionnaire (MDQ) in people with bipolar disorder (BD). Methods: We systematically searched five databases using standard search terms, and relevant articles published between May 1990 and November 30, 2021 were collected and reviewed. Results: Ninety-three original studies were included (n=62,291). At the recommended cutoffs for the BI, HCL-32, BSDS, MDQ, and RMS, the pooled sensitivities were 0.82, 0.75, 0.71, 0.71, and 0.78, respectively, while the corresponding pooled specificities were 0.73, 0.63, 0.73, 0.77, and 0.72, respectively. However, there was evidence that the accuracy of the BI was superior to that of the other tests, with a relative diagnostic odds ratio (RDOR) of 1.22 (0.98-1.52, p < 0.0001). The RMS was significantly more accurate than the other tests, with an RDOR (95%CI) of 0.79 (0.67-0.92, p < 0.0001) for the detection of BD type I (BD-I). However, there was evidence that the accuracy of the MDQ was superior to that of the other tests, with an RDOR of 1.93 (0.89-2.79, p = 0.0019), for the detection of BD type II (BD-II). Conclusion: The psychometric properties of two new instruments, the BI and RMS, in people with BD were consistent with considerably higher diagnostic accuracy than the HCL-32, BSDS, and MDQ. However, a positive screening should be confirmed by a clinical diagnostic evaluation for BD.

ABSTRACT

Abstract This article aims to analyze the association between characteristics of death - type of certifier and place of death - and the odds of an external cause death being certified as unspecified in Brazil. Cross-sectional study of deaths due to external causes from the Mortality Information System, 2017. Unspecified external cause (UEC) is the outcome variable in the models. Type of certifier physician, place of death and the interaction of these variables were the explanatory variables. Confounders were controlled by multiple logistic regression. UEC were the initial underlying cause for 22% of the 159,720 deaths from external causes in Brazil and 31% of hospital deaths issued by coroners. After adjustment for confounders, the odds of UEC in a hospital death certified by a coroner was 98% greater (OR=1.98; 95%CI: 1.53; 2.56) than in a home/street death issued by another certifier. This was greater than the odds for certifications by coroners (OR=1.23; 95%CI: 1.14; 1.33) and hospital deaths (OR=1.44; 95%CI: 1.32; 1.58). External causes certified by coroners and/or occurring in hospitals have a higher presence of UEC than other deaths; and indicate the need for coordinated initiatives by the health and public security sectors.


Resumo O objetivo deste artigo é analisar a associação entre características do óbito - tipo de certificador e local do óbito - e a chance de um óbito por causa externa ser certificado como inespecífico no Brasil. Estudo transversal com dados do Sistema de Informações sobre Mortalidade de 2017. Causa externa inespecífica (CEI) é a variável desfecho nos modelos. As exposições de interesse foram tipo de médico certificador, local do óbito e a interação destas variáveis. Variáveis confundidoras foram controladas por regressão logística múltipla. As CEI foram a causa básica inicial de 22% dos 159,7 mil óbitos por causas externas no Brasil e 31% dos óbitos hospitalares emitidos por médicos-legistas. Após ajuste para confundidores, a chance de CEI em um óbito hospitalar certificado por legista foi 98% maior (OR=1,98; IC95%: 1,53; 2,56) do que em um óbito domiciliares/via pública emitido por outro certificador. Esta foi maior do que as chances para certificação por legista (OR=1,23; IC95%: 1,14; 1,33) e óbito hospitalar (OR=1,44; IC95%: 1,32; 1,58). As causas externas certificadas por médicos-legistas e/ou ocorridas em hospitais têm maior presença de CEI do que outras mortes; e indicam a necessidade de iniciativas coordenadas dos setores da saúde e segurança pública.

ABSTRACT

RESUMEN Fundamento: La electroforesis de proteínas y las cadenas ligeras libres en suero son técnicas utilizadas en el diagnóstico del mieloma múltiple. Sin embargo, la utilidad diagnóstica de ambas pruebas puede variar según el método empleado y condiciones reales del medio donde se realicen. Objetivo: Determinar el valor diagnóstico de la electroforesis de proteínas y de las cadenas ligeras libres en suero en el mieloma múltiple. Metodología: Se realizó un estudio retrospectivo de los parámetros electroforesis de proteínas en suero y cadenas ligeras libres en suero a 43 pacientes con diagnóstico de mieloma múltiple por evaluación de la médula ósea. La electroforesis de proteínas se realizó por el método convencional de separación de proteínas sobre papel de acetato de celulosa y para las cadenas ligeras libres se aplicó un ensayo inmunoturbidimétrico en el que se usó un analizador químico (Cobas 311). Se calcularon 7 parámetros que evaluaron la exactitud diagnóstica. Resultados: Todos los parámetros que evaluaron la exactitud diagnóstica estuvieron dentro de los intervalos de confianza en ambas pruebas. Conclusiones: La electroforesis de proteínas y las cadenas ligeras libres en suero son ensayos de gran utilidad en el diagnóstico del mieloma múltiple y se deben utilizar en conjunto para la mayor captación posible de casos.


ABSTRACT Background: Protein electrophoresis and serum free light chains are techniques used in the diagnosis of multiple myeloma. However, the diagnostic utility of both tests may vary according to the method used and the actual conditions of the environment where they are performed. Objective: To determine the diagnostic value of protein electrophoresis and serum free light chains in multiple myeloma. Methodology: A retrospective study of serum protein electrophoresis parameters and serum free light chains was conducted in 43 patients diagnosed with multiple myeloma by bone marrow evaluation. Protein electrophoresis was completed by the conventional method of protein separation on cellulose acetate paper and for free light chains an immunoturbidimetric assay was applied in which a chemical analyzer (Cobas 311) was used. Seven parameters were calculated to evaluate diagnostic accuracy. Results: All parameters assessing diagnostic accuracy were within confidence intervals in both tests. Conclusions: Protein electrophoresis and serum free light chains are very useful assays in the diagnosis of multiple myeloma and should be used in conjunction for the highest possible approval of cases.

ABSTRACT

INTRODUCTION: Supine-To-Stand task is a basic activity of daily life capable of quickly and simply tracking motor functional competence. Its performance can be assessed quantitatively and qualitatively, respectively, by time and categories identified bychecklists. High-reliability levels were founded in studies with time investigation. However, reliability levels are lower in studies with qualitative measures due to thepossible evaluator subjectivity. OBJECTIVE: To determine the level of reliability of the Supine-To-Stand task in the elderly. METHODS: The convenience sample consisted of 49 elderly people (≥60 years), free from dementia or any disease that prevented them from carrying out the Supine-To-Stand task without assistance. The study was basedon Reliability Study Reporting Guidelines. The participants were filmed performing the Supine-To-Stand task using a cell phone video camera and the images were decoded bytwo trained evaluators. The process of collecting and analyzing the videos was carried out from July to November 2019. The intra- and inter-rater reliability was analyzed by the Kappa coefficient (p≤0.05). RESULTS: The coefficients found for intra-rater reliability wereK=0.761 and 0.542; 0.744 and 0.525; 0.692 and 0.684 and, inter-evaluators K=0.527, 0.342 and 0.766, respectively, for upper limbs, axial region and lower limbs. CONCLUSION: In general, for the three-body regions described by the checklist used, coefficients fromreasonable to substantial reliability were found, both for intra- and inter-rater analyses.


INTRODUÇÃO: A tarefa de levantar-se do solo a partir da posição decúbito dorsal é uma atividade básica da vida diária capaz de rastrear de forma rápida e simples a competência funcional motora. Seu desempenho pode ser avaliado de forma quantitativa e qualitativa, respectivamente, por tempo e categorias identificadas por listas de checagem. Níveis de confiabilidade em estudos que investigaram o tempo elevados. Porém, a confiabilidade das medidas qualitativa sofre maior oscilação devido à possível subjetividade do avaliador. OBJETIVO: Determinar o nível de confiabilidade da tarefa de levantar-se do solo em idosos. MÉTODOS: A amostra de conveniência foi composta por 49 idosos (≥60 anos), livres de demência ou qualquer doença que os impedisse de realizar a tarefa de levantar do solo sem auxílio. O estudo baseou-se em Diretrizes para Relatórios de Estudos de Confiabilidade. Os participantes foram filmados por meio de câmera de vídeo de celular, realizando a tarefa de levantar-se do solo e as imagens foram decodificadas por dois avaliadores treinados. O processo de coleta e análise dos vídeos foi realizado de julho à novembro de 2019. A confiabilidade intra e inter-avaliadores foi analisada pelo Coeficiente Kappa (p≤0,05). RESULTADOS: Os coeficientes encontrados para a confiabilidade intra-avaliadores foram K=0,761 e 0,542; 0,744 e 0,525; 0,692 e 0,684 e, inter-avaliadores K=0,527, 0,342 e 0,766, respectivamente, para membros superiores, região axial e membros inferiores. CONCLUSÃO: Em geral, para as três regiões corporais descritas pela lista de checagem utilizada foram encontrados coeficientes de razoável à substancial confiabilidade, tanto para análises intra quanto inter-avaliadores.

ABSTRACT

SUMMARY OBJECTIVE: The main objective of this study was to evaluate intra- and inter-rater reliability in the analysis of digital images of donor areas for skin in burn patients using the CaPAS plugin in the ImageJ®. METHODS: Donor sites were reviewed by two independent reviewers in duplicate. The capture of images was standardized on the same device and distance (with a millimeter ruler), without a flash. The evaluators were trained to capture the images and use the plugin. RESULTS: We selected 70 images from donor areas, from men and women between 18 and 60 years old. In the analysis of intra-examiner reliability, eight of the nine variables exhibited excellent reliability (0.985-0.998) and one (entropy) exhibited good reliability (0.525). The same was true for the inter-examiner analysis: excellent reliability for eight variables (0.824-0.993) and good reliability for entropy (0.501). CONCLUSIONS: The CaPAS plugin has proven to be a reliable tool for use in research in skin donor areas in burns, as demonstrated by its excellent intra- and inter-examiner reliability values. This is a pioneering study in the quantitative assessment of skin donor areas in burn patients using the CaPAS plugin.

ABSTRACT

Resumen Introducción: Una terapia emergente para el cáncer de colon es la neoadyuvancia, en casos seleccionados. Dicha selección se basa en el análisis preoperatorio de imágenes mediante tomografía computada. Objetivo: Nuestro objetivo es determinar la exactitud diagnóstica del examen para estadificar el cáncer de colon y su correlación entre radiólogos expertos. Materiales y Método: Estudio de exactitud diagnóstica. Previo cálculo muestral se seleccionaron aleatoriamente 47 pacientes con adenocarcinoma colónico resecado con intención curativa e imágenes hasta 60 días previo cirugía. Se evaluó profundidad de invasión tumoral e invasión linfonodal por 2 radiólogos expertos y ciegos entre sí. Las diferencias fueron auditadas por un tercer radiólogo experto. Se compararon resultados con la biopsia, calculando la sensibilidad, especificidad, valor predictivo negativo, valor predictivo positivo y exactitud diagnóstica del examen. Se calculó la concordancia entre radiólogos mediante el índice de kappa. Resultados: La exactitud para diferenciar tumores T3-T4 de T1-T2 fue del 89,4%. En cambio, la capacidad para diferenciar tumores T4 de los T3 fue de un 65,9%. La exactitud para determinar un N (+) fue de un 66%. La concordancia entre radiólogos fue de 0,929 para identificar tumores T1-2, de 0,602 para T3, de 0,584 para T4. Para determinar un N (+), la concordancia fue de 0,521. Conclusión: La exactitud diagnóstica de la tomografía computada en cáncer de colon es adecuada para distinguir tumores avanzados. Sin embargo, su capacidad para discriminar entre T3 y T4, los N (+) y la baja concordancia entre radiólogos, sugiere la necesidad de buscar técnicas imagenológicas complementarias.


Introduction: Neoadjuvant therapy is an emerging treatment for selected cases of colon cancer. The decision is based on the analysis of preoperative images taken by computed tomography. However, its ability to discriminate those who could benefit from this therapy is unknown. Aim: Our objective is to determine the diagnostic accuracy of computed tomography to evaluate the colon cancer stage and its correlation among expert radiologists. Materials and Method: Diagnostic accuracy study. After sample size calculation, we randomly selected 47 patients who underwent a colonic adenocarcinoma resection with curative intent and had available images up to 60 days after surgery. The depth of tumor and lymph nodal invasion were evaluated by two expert radiologists, blinded to each other. The differences between radiologists were audited by a third one. The results were correlated with biopsy as the gold standard. We calculated sensitivity, specificity, negative predictive value, positive predictive value, and diagnostic accuracy of computed tomography. The agreement between radiologists was calculated using the kappa index. Results: The accuracy to differentiate T3-T4 tumors from T1-T2 was 89.4%. In contrast, ability to differentiate T4 tumors from T3 tumors was 65.9%. The accuracy to determine an N (+) was 66%. Agreement between radiologists was 0.929 to identify T1-2, 0.602 for T3, 0.584 for T4 tumors. To determine an N (+), the concordance was 0.521. Conclusion: Diagnostic computed tomography accuracy in colon cancer is adequate to differentiate advanced tumors. However, its ability to discriminate between T3 and T4, N (+) and the low agreement between radiologists suggests the need for complementary imaging techniques.

ABSTRACT

OBJECTIVE@#To investigate the accuracy and safety of pedicle screw placement assisted by orthopedic robot and C-arm fluoroscopy.@*METHODS@#The clinical data of 36 patients with spinal diseases underwent surgical treatment from January 2019 to August 2020 was retrospectively analyzed. Among them, 18 cases were implanted pedicle screws assisted by orthopaedic robot(observation group), including 12 males and 6 females, aged from 16 to 61 years with an average of (38.44±3.60) years;there were 1 case of adolescent scoliosis, 1 case of spinal tuberculosis, 7 cases of lumbar spondylolisthesis, 4 cases of thoracic fracture and 5 cases of lumbar fracture. Another 18 cases were implanted pedicle screws assisted by C-arm fluoroscopy(control group), including 10 males and 8 females, aged from 18 to 58 years with an average of (43.22±2.53) years;there were 1 case of adolescent scoliosis, 6 cases of lumbar spondylolisthesis, 6 cases of thoracic fracture and 5 cases of lumbar fracture. The intraoperative fluoroscopy times, nail placement time and postoperative complications were recorded in two groups. CT scan was performed after operation. The Gertzbein-Robbins standard was used to evaluate the accuracy of pedicle screw placement which was calculated.@*RESULTS@#The number of intraoperative fluoroscopy in observation group was(6.89±0.20) times, which was significantly higher than that in control group(14.00±0.18)times(P<0.05). The placement time of each screw in observation group was(2.56±0.12) min, which was significantly different from that in control group(4.22±0.17) min (P<0.05). One case of incision infection occurred in control group after operation, and recovered after active dressing change. During the follow-up period, no serious complications such as screw loosening and fracture occurred in two groups, and there was no significant difference in complications between two groups(P>0.05). A total of 107 screws were placed in observation group, including 101 screws in class A, 4 in class B, 2 in class C, 0 in class D and 0 in class E, the accuracy rate of pedicle screw placement=[(number of screws in class A+B) / the number of all screws placed in the group] ×100%=98.1%(105/107); and a total of 104 screws were placed in control group, including 90 screws in class A, 4 in class B, 5 in class C, 5 in class D and 0 in class E, the accuracy rate of pedicle screw implantation=[(number of screws in class A+B/the number of all screws placed in the group]×100%=90.3% (94/104); there was significant difference between two groups (P<0.05).@*CONCLUSION@#Orthopaedic robot assisted pedicle screw placement has the advantages of less fluoroscopy times, shorter screw placement time and higher accuracy, which can further improve the surgical safety and has a broad application prospect in the orthopaedic.

ABSTRACT

Objective We used standardized patients to evaluate the accuracy and explore the influencing factors of the diagnosis of unstable angina pectoris and type 2 diabetes by primary healthcare providers in Sichuan rural areas,aiming to provide a scientific basis for improving the diagnosis accuracy of primary healthcare providers for the two chronic diseases. Methods A multi-stage stratified random cluster sampling method was adopted to select 100 villages from 50 townships in 5 districts/counties in Zigong city,Sichuan province. General and internal medicine practioners who were on duty on the survey day were enrolled in the survey.Two rounds of data collection were conducted.In the first round,the basic information of providers from township health centers and village clinics was collected.One month after the the first survey,standardized patients were used to collect the information related to the diagnosis of unstable angina pectoris and type 2 diabetes by rural primary providers.Logistic regression was carried out to analyze the factors influencing the diagnosis accuracy. Results A total of 172 rural primary healthcare providers were enrolled in the survey,who completed 186 standardized patient visits and showed the correct diagnosis rate of 48.39%.Specifically,the correct diagnosis rates of unstable angina pectoris and type 2 diabetes were 18.68%(17/91) and 76.84%(73/95),respectively.The providers with medical practitioner qualifications were more likely to make correct diagnosis(OR=4.857,95%CI=1.076-21.933, P=0.040).The providers who involved more necessary consultation and examination items in the diagnosis process had higher probability of correct diagnosis(OR=1.627,95%CI=1.065-2.485, P=0.024).Additionally,the providers were more likely to make a correct diagnosis for type 2 diabetes than for unstable angina pectoris(OR=6.306,95%CI=3.611-11.013, P<0.001). Conclusions The overall diagnosis accuracy of unstable angina pectoris and type 2 diabetes was relatively low among primary healthcare providers in Sichuan rural areas.The training of diagnosis process can be taken as a key for improving providers' practice ability so as to increase the diagnosis accuracy of chronic diseases.

ABSTRACT

BACKGROUND Leprosy is a chronic infectious disease, still endemic in many countries that may lead to neurological, ophthalmic, and motor sequelae if not treated early. Access to timely diagnosis and multidrug therapy (MDT) remains a crucial element in the World Health Organization's strategy to eliminate the disease as a public health problem. OBJECTIVES This systematic review aims to evaluate the accuracy of rapid point-of-care (POC) tests for diagnosis of leprosy. METHODS Searches were carried out in electronic databases (PubMed, EMBASE, CRD, Cochrane Library and LILACS) in April 2021 for patients with suspicion or confirmatory diagnostic of leprosy, classified in multibacillary (MB) or paucibacillary (PB) cases, performing rapid POC serological tests compared to clinical evaluation, smear microscopy and immunohistochemistry analysis. Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2). A meta-analysis was undertaken to generate pooled estimates of diagnostic parameters, presenting sensitivity, specificity and diagnostic odds ratio (DOR) values. The review protocol was registered at PROSPERO, CRD # 42014009658. FINDINGS From 893 potentially relevant references, 12 articles were included reporting 16 diagnostic tests accuracy studies with 5395 individuals enrolled. Meta-analysis of NDO-LID and PGL-I tests data in MB patients showed sensitivity and specificity [95% confidence interval (CI)] of 0.83 (0.71-0.91), 0.91 (0.72-0.97); and 0.92 (0.86-0.96), 0.93 (0.78-0.98); respectively, with high heterogeneity among the studies. MAIN CONCLUSIONS Our results can inform policymakers regarding the possibility of implementing accurate, rapid POC tests for leprosy in public health services, especially within primary health care.

ABSTRACT

ABSTRACT The aim of the present study is to investigate the impact of health literacy of Iranian users on the accuracy of information on COVID-19 in virtual social networks. This is applied descriptive survey. The population includes all Iranian users of virtual networks (Telegram, WhatsApp, Twitter, Instagram and etc.). In this study, 121 questionnaires were confirmed and studied. For descriptive statistics, SPSS (ver. 32) and for testing hypothesis, Lisrel have been used. The research findings show that according to Iranian users, Internet is the main source for obtaining information on COVID-19. Moreover, the most popular virtual network is WhatsApp. The aim of using virtual social networks is to access to news and information. The results of structural equations show that there is positive meaningful relation between the rate of health literacy and the accuracy of information on COVID-19 (p > 0.000, β = 0.561). In addition, the health literacy can explain 40 percent variance of the accuracy of information on COVID-19 in virtual social networks. Moreover, the results show that there is meaningful difference between the educational level of Iranian users and the health literacy and accuracy of information on COVID-19 in virtual social networks. Concerning the results of this study and meaningful relation between the health literacy level and attention to accuracy of the information on COVID-19 in Iranian users, the authorities of health system are recommended to consider special planning and policies to increase the health literacy level of users in social networks. In this way, users will be able to verify the accuracy of information on COVID-19 by increasing their health literacy level and therefore, there would be less losses due to unawareness of health literacy and its adverse effect.


RESUMEN El objetivo del presente estudio es investigar el impacto de la alfabetización en salud relacionada con la COVID-19 en los usuarios iraníes de las redes sociales virtuales. Se aplicó una encuesta descriptiva, que incluyó a todos los usuarios iraníes de redes sociales virtuales (Telegram, WhatsApp, Twitter, Instagram, etc.). En el estudio se confirmaron y estudiaron 121 cuestionarios. Para estadística descriptiva se utilizó SPSS (versión 32) y Lisrel, para probar la hipótesis. La investigación indicó que, según los usuarios iraníes, Internet es la principal fuente de información sobre COVID-19; además, la red virtual más popular es WhatsApp. El objetivo del uso de las redes sociales virtuales es acceder a noticias e información. Los resultados de las ecuaciones estructurales muestran que existe una relación significativa y positiva entre la tasa de alfabetización en salud y la precisión de la información sobre COVID-19 (p > 0,000; β = 0,561). Asimismo, la alfabetización en salud puede explicar una variación del 40 % en la precisión de la información sobre COVID-19 en las redes sociales virtuales. También que existe una diferencia significativa entre el nivel educativo de los usuarios iraníes, la alfabetización en salud y la precisión de la información sobre COVID-19 en las redes sociales virtuales. Teniendo en cuenta los resultados de este estudio, se recomienda a las autoridades del sistema de salud que consideren una planificación y políticas especiales para aumentar el nivel de alfabetización en salud de los usuarios en redes sociales. De esta manera, estos últimos podrán verificar la información sobre COVID-19 y, por lo tanto, serían menores las pérdidas por desconocimiento.

ABSTRACT

Abstract Introduction: The Sunnybrook Facial Grading System (SFGS) is a scale to evaluate facial function in three domains, namely resting symmetry, voluntary move-ments, and synkinesis. It is commonly used in scientific research and clinical practice to assess and monitor people with facial paralysis. Objective: To translate and cross-culturally adapt the SFGS, develop a version for the Brazilian population (SFGS - Brazil) and analyze its psychometric properties, including validity, interrater reliability and responsiveness. Methods: A multidisciplinary panel translated and adapted the SFGS into Brazilian Portuguese, creating the SFGS-Brazil version. Next, content validation was carried out by a panel of four physical therapists with clinical experience in caring for people with facial paralysis, in addition to interrater reliability and scale responsiveness after physical therapy intervention. Results: For SFGD validation, committee agreement rate and the content validity index were greater than 90%. Agreement (interrater reliability) was excellent for most items and overall (intraclass correlation coefficient = 0.99; p < 0.000) and the scale proved to be responsive, indicating post-intervention improvement (t = 10.66; p = 0.000). Conclusion: The domains and items of the SFGS-Brazil are conceptually equivalent to those of the original version, and the instrument displays adequate psychometric properties, including validity, agreement and responsiveness. The SFGS-Brazil is suitable for the Brazilian population and can be used in scientific studies and clinical practice.


Resumo Introdução: O Sunnybrook Facial Grading System (SFGS) é uma escala para avaliar a função facial em três domínios, incluindo simetria em repouso, movimentos voluntários e sincinesias. Essa escala é comumente utilizada em pesquisas científicas e na prática clínica para a avaliação e acompanhamento de pessoas com paralisia facial. Objetivo: Traduzir e adaptar transculturalmente o SFGS, elaborar a versão para a população brasileira (SFGS-Brasil) e analisar suas propriedades psicométricas, incluindo validade, confiabilidade interexaminadores e responsividade. Métodos: Um comitê multidisciplinar traduziu e adaptou o SFGS para o português do Brasil, gerando a versão SFGS-Brasil. Após esta fase, realizou-se a validação de conteúdo por um comitê de quatro fisioterapeutas com experiência clínica em atendimento de pessoas com paralisia facial, além da confiabilidade interexaminadores e a responsividade da escala após intervenção fisioterapêutica. Resultados: Para a validação do SFGS, a taxa de concordância do comitê total e o índice de validade do conteúdo mostraram-se maiores que 90%. A concordância (confiabilidade interexaminadores) mostrou-se excelente para maioria dos itens e para o total (coeficiente de correlação intraclasse = 0,99; p < 0,000), e o instrumento mostrou-se responsível, podendo-se identitificar melhora segundo o SFGS-Brasil após a intervenção (t = 10,66; p = 0,000). Conclusão: O SFGS-Brasil possui equivalência conceitual dos domínios e itens à versão original, possui propriedades psicométricas adequadas, incluindo validade, concordância e responsividade. O SFGS-Brasil é adequado para a população brasileira, podendo ser usado em estudos científicos e na prática clínica.

ABSTRACT

Objectives: This study aimed to determine the accuracy of prenatal sonographic gender determination during foetal anomaly ultrasound and the overall sensitivity pattern in our institution.Materials and Methods: A cross-sectional study of 520 consenting pregnant women who presented for foetal anomaly scans within a one-year period in our institution. The diagnostic accuracy of gender determination during the anomaly and delayed scans were determined by comparing the sonographic gender with the birth gender and calculating sensitivity, specificity, positive predictive value and negative predictive value. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics, frequencies, Mc-Nemar chi-square test were used at 5% level of significance. Results: The mean maternal age was 31.51 ±5.02years. Of the 520 consenting pregnant women studied, 16(6.0%) women were having twin gestation. Four hundred and ninety-seven (92.7%) genders were determined during foetal anomaly scan. The accuracy of the ultrasonography (US) examination performed by the resident doctors was 98.02% while the accuracy of the scan performed by the consultant radiologists was 100%. Overall, the accuracy of the gender determination on ultrasound was 98.69%. The general specificity and sensitivity of the US were 98.71 % and 98.68% respectively while the positive and negative predictive value were 99.01 % and 98.29% respectively. Conclusion: The accuracy of ultrasound examination in detecting foetal gender during foetal anomaly ultrasound is high with equally high predictive values and therefore it is recommended as a mandatory variable during anomaly scans. There is need for continuous training of resident doctors or operators in lower cadre to improve their competency in foetal gender determination.
