ABSTRACT

ABSTRACT Objective: To assess the level of oral cancer awareness and risk factors perception and the relationship between this awareness and the sociodemographic and behavioral characteristics. Material and Methods: This descriptive study was conducted among rural and urban residents in Lagos State, Nigeria. A multi-stage random sampling method was utilized. The sociodemographic and behavioral characteristics of respondents, as well as their knowledge about oral cancer risk factors, were assessed with a validated questionnaire. The bivariate association was done using an independent t-test and one-way ANOVA. Multivariate regression was used to determine the association between predictor variables and oral cancer knowledge scores. The statistical significance level is set at p<0.05. Results: 590 participants between 18 and 82 years (mean age 34.5 ±13.7) completed the survey. The prevalence of cigarette smoking was 25.7%, of which 16 (1.5%) were heavy smokers (20+ cigarettes per day). The prevalence of alcohol consumption was 66.1%, with 57 (9.7%) being heavy drinkers, consuming drinks for 5-7 days of the week. A high proportion of the respondents (>60%) exhibited gaps in their knowledge of oral cancer. Uneducated participants had lower oral cancer knowledge than those with >12 years of formal education (aOR = 5.347; 95% CI: 4.987-6.240). Participants who were smokers had lower oral cancer knowledge compared with non-smokers (aOR = 3.341; 95% CI: 2.147-4.783); Participants who consumed alcohol had more deficient oral cancer knowledge compared with non-drinkers (aOR = 1.699; 95% CI: 1.087-2.655); While heavy smokers aOR = 4.023; 95% CI: 3.615-4.825) and heavy drinkers aOR = 4.331; 95% CI: 3.158-5.939) had lower oral cancer knowledge compared with those who did not abuse both substances. Conclusion: A high proportion of the respondents exhibited gaps in their knowledge of oral cancer in their responses. Delayed diagnosis of oral cancer can be reduced by increasing the awareness and knowledge of the populace about risk factors and also in the recognition of its signs and symptoms.

ABSTRACT

ABSTRACT Objective: To assess the impact of Molar Incisor Hypomineralization (MIH) and confounding factors on oral health-related quality of life (OHRQoL) according to the perception of 8 to 10-year-old children and their parents/caregivers. Material and Methods: A cross-sectional study including 403 students aged 8-10 years was carried out, in which OHRQoL was measured using the Child Perceptions Questionnaire administered to both children and parents/caregivers. The diagnosis of MIH was performed according to the previously proposed index. Dental caries experience, malocclusion, and sociodemographic factors were evaluated as confounders. Cluster analysis and Poisson regression with robust variance (p<0.05) were performed. Results: The prevalence of MIH was 13.4%. Parents/caregivers of children with MIH in incisors showed a higher impact prevalence in the emotional well-being domain (PR=1.92; 95%CI=1.16-3.19). Children with hypoplasia had a higher prevalence of negative impact on OHRQoL in the oral symptoms domain (PR=1.51; 95%CI=1.03-2.23). According to the perception of parents/caregivers, dental caries experience had a negative impact on the quality of life of students in the emotional well-being domain (PR=4.19; 95%CI=1.06-16.49) and in the total questionnaire score (PR=3.21; 95%CI=1.06-9.71). Conclusion: According to the perception of parents/caregivers, children with MIH in incisors showed a greater impact on OHRQoL. Additionally, the presence of hypoplasia affected the self-perception of OHRQoL in children, and caries experience influenced the OHRQoL of children, as perceived by parents/caregivers.

ABSTRACT

Abstract The quality, efficacy, and safety of medicines are usually verified by analytical results. Measurement uncertainty is a critical aspect for the reliability of these analytical results. The pharmacopeial compendia usually adopt a simple acceptance rule that does not consider information from measurement uncertainty. In this work, we compared decision-making using simple acceptance and decision rules with the use of guard-band for multiparameter evaluation of ofloxacin ophthalmic solution and acyclovir topical cream. Ciprofloxacin ophthalmic solution and acyclovir topical cream samples were subject to pharmacopeial tests and assays. Multivariate guard-band widths were calculated by multiplying the standard uncertainty (u) by an appropriate multivariate coverage factor (k'). The multivariate coverage factor (k') was obtained by the Monte Carlo method. According to the simple acceptance rule, all the results obtained for ciprofloxacin ophthalmic solution and acyclovir topical cream are within the specification limits. However, the risk of false conformity decisions increases for ciprofloxacin tests. Decisions made using the simple acceptance rule and decision rules with the use of guard-band may differ. The simple acceptance rule may increase the risk of false conformity decisions when the measured value is close to the regulatory specification limits and/or when the measurement uncertainty value is inappropriately high. Nevertheless, the guard-band decision rule will always reduce the risk of false conformity decisions. Therefore, using information on measurement uncertainty in conformity assessment is highly recommended to ensure the proper efficacy, safety, and quality of medicines.

ABSTRACT

Este estudo objetivou avaliar aspectos que exercem influência sobre a contagem bacteriana total (CBT) e a contagem de células somáticas (CCS) do leite e avaliar a adequação das amostras do produto à Instrução Normativa nº 76, de 26 de novembro de 2018, do Ministério da Agricultura e Pecuária do Brasil (IN 76). A pesquisa foi realizada em propriedades rurais da microrregião de Birigui, São Paulo, Brasil, e se baseou em coleta de dados, por entrevista estruturada, e coletas de leite nas propriedades. Foi realizada amostragem por conveniência, sendo escolhidos 15 produtores de cada estrato (de acordo com a produção diária de leite: pequeno - até 100 L; médio - 101 a 300 L; grande - mais de 300 L), totalizando 45 produtores de leite. Participaram da pesquisa somente propriedades com base da alimentação volumosa em sistema de pastejo ou em semiconfinamento. Para avaliar a influência de diferentes fatores sobre a contagem bacteriana total (CBT) e a contagem de células somáticas (CCS), separadamente, realizou-se regressão multivariada. Ainda, foi determinado o coeficiente de correlação entre variáveis desta pesquisa. As variáveis resposta foram transformadas em logaritmo para normalização dos dados. Foi feita comparação entre os resultados da pesquisa e os parâmetros da IN 76 para verificar o cumprimento das normas pelos produtores. Foram encontrados valores médios de 6.986.977,818.961.790,7 UFC/mL para CBT e de 608.911,1 ± 414.802,9 CS/mL para CCS. A utilização de tanque de resfriamento individual mostrou-se favorável à baixa CBT, em comparação com não uso de tanque ou uso de tanque comunitário, conforme o esperado, pois quanto mais tempo leva para resfriar o leite, maior é a proliferação de bactérias no produto. Foi verificado que o leite de produtores que realizam o California Mastitis Test (CMT) com maior frequência apresentou CCS mais elevada, o que não era esperado. As análises físico-químicas médias foram densidade 1,031 g/mL a 15°C, índice crioscópico -0,538 °H, teor de proteína 3,58%, teor de gordura 4,06%, extrato seco total 12,75%, extrato seco desengordurado 8,69%, acidez titulável 16,2 °D e estabilidade ao álcool (Alizarol 72%) 100%. Em 13,3% (6/45) das amostras foi detectada presença de antibióticos. Considerando a IN 76, o leite de somente 8,9% (4/45) dos produtores apresentou-se adequado simultaneamente para todos os parâmetros analisados (CBT, CCS, densidade, índice crioscópico, proteína, gordura, extrato seco total, extrato seco desengordurado, acidez titulável, estabilidade ao alizarol e pesquisa de antibióticos). A utilização de tanque de resfriamento individual e a realização de CMT favoreceram menor CBT e maior CCS, respectivamente.


This study aimed to evaluate aspects that exerts influence on the total bacterial count (TBC) and somatic cell count (SCC) of milk and evaluate the conformity of the samples to the Normative Instruction no. 76, from November 26, 2018, of the Brazilian Agriculture and Livestock Ministry (NI 76). The research was done in farms around Birigui micro-region, São Paulo State, Brazil, and was based on data collection obtained by structured interviews and milk collection in the farms. Convenience sampling was carried out from 15 producers of each stratum (according to daily milk production: small - up to 100 L; medium - 101 to 300 L; large - more than 300 L), totalizing 45 milk producers. Only farms with grazing or semi-feedlot system for roughage feeding base were included. To evaluate the influence of different factors on Total Bacterial Count (TBC) and Somatic Cell Count (SCC), separately, a multivariate regression was done. Moreover, the correlation coefficient among variables was determined. The response variables were transformed into logarithms for the normalization of the data. A comparison between results and NI 76 parameters was done to verify the standard compliance by producers. Mean TBC was 6.986.977,8 ± 18.961.790,7 CFU/mL and mean SCC was 608.911,1414.802,9 cells/mL. The use of individual cooler tank was favorable to lower TBC, compared with the non-use of the tank or with the use of the communitarian tank, as expected, since the longer it takes to cool the milk, the higher the proliferation of bacteria in the product. It was verified that milk from farmers that more frequently perform California Mastitis Test (CMT) showed higher SCC, which was not expected. The average physicochemical analyzes were density 1.031 g/mL at 15°C, cryoscopic index -0.538 °H, protein content 3.58%, fat content 4.06%, total dry extract 12.75%, dry extract defatted 8.69%, titratable acidity 16.2 °D and alcohol stability (Alizarol 72%) 100%. The presence of antibiotics was detected in 13.3% (6/45) of the samples. Considering NI 76, milk from only 8.9% (4/45) farmers were proper simultaneously for all the parameters analyzed (TBC, SCC, density, cryoscopic index, protein, fat, total dry extract, defatted dry extract, titratable acidity, alizarol stability and antibiotics). The use of individual cooling tank and the CMT performance support lower TBC and higher SCC respectively.

En el 13,3% (6/45) de las muestras se detectó la presencia de antibióticos. Considerando la IN 76, la leche de solo el 8,9% (4/45) de los productores se presentó adecuado simultáneamente para todos los parámetros analizados (CBT, CCS, densidad, índice crioscópico, proteína, grasa, extracto seco total, extracto seco desgrasado, acidez titulable, estabilidad al alizarol e investigación de antibióticos). El uso de un tanque de enfriamiento individual y la realización de CMT favorecieron un CBT más bajo y un CCS más alto respectivamente.

Es importante determinar predictores tempranos de enfermedad que nos ayuden a estratificar aquellos pacientes con mayor riesgo de fallecer. Se pretende estudiar el comportamiento del puntaje APP (APPS) como predictor de ello, basados en algunos reportes de uso y utilidad en el SDRA. no COVID-19. OBJETIVO: Determinar si el APPS es útil como predictor de mortalidad en SDRA. por COVID-19 grave. PACIENTES Y MÉTODO: Se realizó un estudio tipo cohorte retrospectivo, incluyendo pacientes de la Unidad de Cuidados Intensivos (UCI), con SDRA. por COVID-19 grave, que ingresaron a la UCI del Hospital Regional Docente de Trujillo (HRDT) en el período abril 2020- abril 2021. Se evalúo la utilidad del APPS como predictor de mortalidad em dicha población. RESULTADOS: El APPS demostró ser un factor asociado a mortalidad en pacientes con SDRA. y COVID-19 grave (RPa 1,34; IC 95% 1,16 a 1,56; p < 0,001). Además, encontramos que, al realizar un modelo de predicción ajustado por edad, sexo, SOFA, APPS, shock, Indice de Charlson (ICh), se comportan como factores asociados a mortalidad el APPS, el sexo masculino (RPa: 1,48; IC 95% 1,09 a 2,049; p < 0,05) y el ICh (RPa: 1,11; IC 95% 1,02 a 1,21; p < 0,05). CONCLUSIÓN: El APPS, el sexo masculino y el ICh son predictores de mortalidad en SDRA. por COVID-19 grave.


BACKGROUND: Mortality in patients with severe COVID-19 who developed severe pneumonia and severe Acute Respiratory Distress Syndrome (ARDS) has been significant despite timely treatment. It is important to determine early predictors of disease that help us to stratify those patients with a higher risk of death. It is intended to study the behavior of the APPS score as a predictor of this, based on some reports of use and usefulness in non-COVID-19 ARDS. AIM: To determine if the APP score is useful as a predictor of mortality in ARDS due to severe COVID-19. METHOD: A retrospective cohort study was carried out, including patients from the Intensive Care Unit (ICU) with ARDS due to severe COVID-19 who were admitted to the ICU of the Trujillo Regional Teaching Hospital (HRDT) in the period March 2020 to March 2021. The usefulness of the APP score as a predictor of mortality in mentioned population was evaluated. RESULTS: The APP score proved to be a factor associated with mortality in patients with ARDS and severe COVID-19 (APR 1.34; 95% CI 1.16 to 1.56; p < 0.001). We also found that when performing a prediction model adjusted for age, sex, SOFA, APP score, shock and Charlson Index (ICh) we found that the APP score, male sex (APR: 1.48; 95% CI 1.09 to 2.049; p < 0.05) and the ICh behave as factors associated with mortality (RPa: 1.11; 95% CI 1.02 to 1.21; p < 0.05). CONCLUSION: The APP score, male sex, and ICh are predictors of mortality in ARDS due to severe COVID-19.

ABSTRACT

SUMMARY: Sex identification of a deceased human individual by means of the mandible is very important for forensic dentistry. The aim of the present study was to determine the sex of Chilean individuals by mandible analysis in panoramic radiographies. Linear and angular parameters of the mandible were analyzed from panoramic radiographies (PR). The study included PR of adult Chilean individuals, of both sexes, with optimum solution and contrast, and which allowed the angles and rami of the mandible to be viewed. Sex was determined by univariate and bivariate discriminant function analysis. The sample consisted of 594 PR of individuals aged between 18 and 84 years. The best sex predictor using univariate discriminant function analysis was the mandibular ramus height (MRH) (74.1 %), followed by the distance from the mental foramen - mandibular base (DMF-MB) (69.1 %) and the bicondylar breadth (BC) (66.7 %). The parameters that presented the lowest sex prediction were the angle of the mandible (AM) with 55.0 % and the distance between mental foramina (DMF) with 53.7 %. The best sex prediction was obtained by the step model of discriminant function analysis (80.2 %), including only three parameters: MRH, BC and DMF-MB. The parameters height of the mandibular ramus, bicondylar breadth and distance from the mental foramen - base of the mandible are good predictors of sex in Chilean individuals when used in conjunction; they are therefore indicated for sex determination in the contemporary Chilean population.


La identificación humana de un individuo fallecido a través de la mandíbula es muy relevante para la odontología forense. El objetivo de este estudio fue estimar el sexo de individuos Chilenos a través del análisis de la mandíbula, utilizando radiografías panorámicas. Fueron analizados parámetros lineales y angulares de la mandíbula, a través de radiografías panorámicas (RP). Se incluyeron RP de individuos chilenos adultos, ambos sexos, con solución y contraste óptimos, y que permitían la visualización de los ángulos y ramas de la mandíbula. Se realizó análisis por función discriminante univariada y bivariada para estimación del sexo. Fueron incluidas 594 RP de individuos entre 18 y 84 años. Para el análisis de función discriminante univariado, la altura de la rama mandibular (ARM) fue el parámetro más predictivo (74,1 %), seguido de la distancia foramen mentoniano - base de la mandíbula (DFM-BM) (69,1 %) y el ancho bicondilar (ABCo) (66,7 %). Los parámetros que presentaron menor predicción sexual fueron el ángulo de la mandíbula (AM) con un 55,0 % y la distancia inter-forámenes mentonianos (DIFM), con el 53.7 %. El análisis por pasos fue el modelo de análisis de función discriminante que presentó la mayor predicción sexual (79,5 %), en el cual fueron incluidos sólo tres parámetros: ARM, ABCo y DFM-BM. Los parámetros altura de la rama de la mandíbula, ancho bicondilar y distancia desde el foramen mentoniano hasta la base de la mandíbula son buenos predictores del sexo en individuos Chilenos cuando utilizados en conjunto y están indicados para estimar el sexo en la población chilena contemporánea.

ABSTRACT

SUMMARY: Colon adenocarcinoma (COAD) is a prevalent disease worldwide, known for its high mortality and morbidity rates. Despite this, the extent of investigation concerning the correlation between COAD's CLCA1 expression and immune cell infiltration remains insufficient. This study seeks to examine the expression and prognosis of CLCA1 in COAD, along with its relationship to the tumor immune microenvironment. These findings will offer valuable insights for clinical practitioners and contribute to the existing knowledge in the field. In order to evaluate the prognostic significance of CLCA1 in individuals diagnosed with colorectal cancers, we conducted a comprehensive analysis using univariate and multivariate Cox regression models along with receiver operating characteristic curve (ROC) analysis. This study was performed on the patient data of COAD obtained from The Cancer Genome Atlas (TCGA) database. Nomograms were developed to anticipate CLCA1 prognostic influence. Furthermore, the CLCA1 association with tumor immune infiltration, immune checkpoints, immune checkpoint blockade (ICB) response, interaction network, and functional analysis of CLCA1-related genes was analyzed. We found that Colon adenocarcinoma tissues significantly had decreased CLCA1 expression compared to healthy tissues. Furthermore, the study revealed that the group with high expression of CLCA1 demonstrated a significantly higher overall survival rate (OS) as compared to the group with low expression. Multivariate and Univariate Cox regression analysis revealed the potential of CLCA1 as a standalone risk factor for COAD. These results were confirmed using nomograms and ROC curves. In addition, protein-protein interaction (PPI) network analysis and functional gene enrichment showed that CLCA1 may be associated with functional activities such as pancreatic secretion, estrogen signaling and cAMP signaling, as well as with specific immune cell infiltration. Therefor, as a new independent predictor and potential biomarker of COAD, CLCA1 plays a crucial role in the advancement of colon cancer.


El adenocarcinoma de colon (COAD) es una enfermedad prevalente a nivel mundial, conocida por sus altas tasas de mortalidad y morbilidad. Sin embargo, el alcance de la investigación sobre la correlación entre la expresión de CLCA1 de COAD y la infiltración de células inmunes sigue siendo insuficiente. Este estudio busca examinar la expresión y el pronóstico de CLCA1 en COAD, junto con su relación con el microambiente inmunológico del tumor. Estos hallazgos ofrecerán conocimientos valiosos para los profesionales clínicos y contribuirán al conocimiento existente en el campo. Para evaluar la importancia de pronóstico de CLCA1 en personas diagnosticadas con cáncer colorrectal, realizamos un análisis exhaustivo utilizando modelos de regresión de Cox univariados y multivariados junto con un análisis de la curva característica operativa del receptor (ROC). Este estudio se realizó con los datos de pacientes de COAD obtenidos de la base de datos The Cancer Genome Atlas (TCGA). Se desarrollaron nomogramas para anticipar la influencia pronóstica de CLCA1. Además, se analizó la asociación de CLCA1 con la infiltración inmunitaria tumoral, los puntos de control inmunitarios, la respuesta de bloqueo de los puntos de control inmunitarios (ICB), la red de interacción y el análisis funcional de genes relacionados con CLCA1. Descubrimos que los tejidos de adenocarcinoma de colon tenían una expresión significativamente menor de CLCA1 en comparación con los tejidos sanos. Además, el estudio reveló que el grupo con alta expresión de CLCA1 demostró una tasa de supervivencia general (SG) significativamente mayor en comparación con el grupo con baja expresión. El análisis de regresión de Cox multivariado y univariado reveló el potencial de CLCA1 como factor de riesgo independiente de COAD. Estos resultados se confirmaron mediante nomogramas y curvas ROC. Además, el análisis de la red de interacción proteína- proteína (PPI) y el enriquecimiento de genes funcionales mostraron que CLCA1 puede estar asociado con actividades funcionales como la secreción pancreática, la señalización de estrógenos y la señalización de AMPc, así como con la infiltración de células inmunes específicas. Por lo tanto, como nuevo predictor independiente y biomarcador potencial de COAD, CLCA1 desempeña un papel crucial en el avance del cáncer de colon.

ABSTRACT

Introducción: El traumatismo craneoencefálico en edades pediátricas constituye un problema de salud relevante a nivel mundial y en Cuba. Objetivo: Determinar los factores pronósticos del trauma craneoencefálico grave en niños que requirieron craneotomía descompresiva. Métodos: Se realizó un estudio transversal correlacional, de tipo serie de casos, en el Servicio de Neurocirugía del Hospital Pediátrico de Camagüey durante el período comprendido desde enero de 2019 a diciembre de 2021. Fueron estudiados un total de 27 niños con traumatismo craneoencefálico grave, que cumplieron con los criterios de selección de la investigación. Las variables analizadas incluyeron: grupo etario, sexo, intensidad de la lesión, técnica quirúrgica, perfusión cerebral y resultados quirúrgicos obtenidos. Resultados: Predominó el grupo etario de 11-18 años (45,5 porciento) y el sexo masculino (72,7 porciento). El mayor puntaje en la variable intensidad de la lesión correspondió con la realización de craneotomías bilaterales (media = 78,63). Se halló disminución significativa (p = 0,024) de la perfusión cerebral en los pacientes con edad menor o igual a 8 años (media = 61,6387) y se encontró más disminuida en los pacientes que requirieron craneotomía bilateral (p = 0,001). Los peores resultados obtenidos correspondieron a los pacientes con edad biológica igual o menor a 8 años, que requirieron craneotomía bilateral. Conclusiones: La edad menor a 8 años se relacionó con mayor deterioro de la perfusión cerebral y peores resultados. La necesidad de craneotomías bilaterales se asoció con mayor intensidad de la lesión encefálica, presión intracraneal preoperatoria más elevada y deterioro de la perfusión cerebral(AU)


Introduction: Cranioencephalic trauma in pediatric ages is a relevant health problem worldwide and in Cuba. Objective: To determine the prognostic factors of severe cranioencephalic trauma in children who required decompressive craniotomy. Methods: A cross-sectional and correlational study of case series type was carried out at the neurosurgery service of Hospital Pediátrico de Camagüey during the period from January 2019 to December 2021. A total of 27 children with severe cranioencephalic trauma who met the research selection criteria were studied. The analyzed variables included age group, sex, injury intensity, surgical technique, cerebral perfusion and obtained surgical outcomes. Results: The age group 11-18 years (45.5 percent) and male sex (72.7 percent) predominated. The highest score in the variable injury intensity corresponded to the realization of bilateral craniotomies (mean = 78.63). A significant decrease (p = 0.024) in cerebral perfusion was found in patients aged 8 years or under (mean = 61.6387) and it was found to be more diminished in patients who required bilateral craniotomy (p = 0.001). The worst obtained outcomes corresponded to patients with a biological age of 8 years or under, who required bilateral craniotomy. Conclusions: Age under 8 years was associated with greater cerebral perfusion impairment and worse outcomes. The need for bilateral craniotomies was associated with greater intensity of the encephalic injury, higher preoperative intracranial pressure and cerebral perfusion impairment(AU)

ABSTRACT

INTRODUCCIÓN: Las infecciones bacterianas en trasplante hepático (TH) son una de las principales causas de morbimortalidad. OBJETIVO: Caracterizar las complicaciones infecciosas bacterianas en el primer mes postrasplante. Pacientes y MÉTODOS: Estudio retrospectivo entre los años 2009-2020. RESULTADOS: 225 pacientes recibieron un TH. 80 (35,5%) desarrollaron al menos un episodio de infección bacteriana en el primer mes postrasplante hepático. Hubo 105 episodios de infección bacteriana con una incidencia de 46,6%. El foco más frecuente fue el abdominal (48,6%) y el microorganismo predominante fue Klebsiella spp. De los 104 aislamientos, el 57,6% presentaron un perfil MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron menor sobrevida al alta hospitalaria en comparación con los que no la presentaron 87,5 versus 94,5% [OR 4,18 (IC 95%: 1,5-11,6)]. En el análisis multivariado la reintervención quirúrgica precoz [OR 4,286 (IC 95%: 1,911-9,61)], mostró un riesgo significativo de desarrollar una complicación infecciosa bacteriana en el primer mes postrasplante. CONCLUSIONES: Tres de cada 10 pacientes presentaron una infección bacteriana en el primer mes postrasplante con una alta incidencia de bacilos gramnegativos MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron una menor sobrevida al alta. La reintervención quirúrgica precoz se identificó como un factor predisponente de infección temprana.


BACKGROUND: Bacterial infections are one of the main causes of morbidity and mortality in liver transplant recipients (LT). Aim: To characterize bacterial infectious complications in the first month an after a liver transplant. METHODS: Retrospective analysis of a cohort of liver transplant recipients who presented at least one bacterial infectious complication in the first month after transplant between 2009 and 2020. RESULTS: 225 patients were analyzed. 80 (35.5%) had a least one documented bacterial infection during the first month after transplant. 105 bacterial infections were documented, with an incidence of 46.6%. The most frequent origin was intra-abdominal (48.6%) and the predominant isolated microorganism was Klebsiella spp. Among 104 isolated microorganisms 57.6% showed MDR/XDR profile. Patients who developed a bacterial infectious complication had a shorter overall survival (OS) after discharge from hospital (87.5% vs 94.5%) [OR 4.18 (IC 95%: 1.5-11,6)]. When multivariate analysis of predisposing factors was performed early surgical reoperation was the only variable associated with an increased risk of developing a bacterial complication in the first month [OR 4.286 (IC 95%: 1.911-9.61)]. CONCLUSIONS: Three out of 10 patients developed a bacterial infectious complication during the first month after liver transplant with a high incidence of gram-negative bacillus MDR/XDR. Patients who presented infectious complications had a shorter OS after discharge, and early reoperation was identified as a predisposing factor of early infectious complications.

ABSTRACT

INTRODUCCIÓN: Las opacidades pulmonares en receptores de trasplante de precursores hematopoyéticos (TPH) representan un desafío diagnóstico y son una causa de morbimortalidad. Existen grandes discrepancias con respecto a la sensibilidad diagnóstica del lavado broncoalveolar (LBA), sus complicaciones, y los factores asociados a la identificación microbiológica. OBJETIVO: Conocer la utilidad del estudio microbiológico del LBA en el diagnóstico, modificación de la conducta médica y estimar las complicaciones y mortalidad asociada al procedimiento, en receptores de TPH con opacidades pulmonares. PACIENTES Y MÉTODOS: Estudio de cohorte, retrospectivo, en adultos receptores de TPH a los que se les realizó una broncoscopía con LBA por presentar opacidades pulmonares, en el Hospital Italiano de Buenos Aires entre el 01/01/2011 y el 31/12/2020. RESULTADOS: De los 189 procedimientos analizados, en 79 se logró un hallazgo microbiológico (41,8%) y 122 permitieron modificar la conducta médica (64,6%). En 11 casos se observaron complicaciones graves dentro de las 12 horas (5,8%) de efectuado el LBA. La mortalidad intrahospitalaria fue de 16,8% (N = 21/125). El valor de neutrófilos en sangre previo al LBA (p = 0,037) y la presencia de nódulos pulmonares como lesión tomográfica predominante (p = 0,029) se asociaron independientemente al hallazgo microbiològico global. CONCLUSIONES: Nuestra investigación apoya la realización del LBA como herramienta diagnóstica en pacientes que reciben un TPH y presentan opacidades pulmonares.


BACKGROUND: Lung opacities are a cause of morbimortality in bone marrow transplant patients, and represent a diagnostic challenge. There are large discrepancies regarding the diagnostic sensitivity of bronchoalveolar lavage (BAL), its complications, and the factors associated with microbiological detection. AIM: To know the usefulness of the microbiological study of BAL in the diagnosis, in the modification in medical behavior and to estimate the complications and associated mortality of this diagnostic procedure in patients transplanted with hematopoietic progenitor cells with pulmonary opacities. METHODS: Retrospective cohort study in bone marrow transplant adult patients who underwent bronchoscopy with BAL due to lung opacities at Hospital Italiano de Buenos Aires between 01/01/2011 and 12/31/2020. RESULTS: Of the 189 BAL analyzed, 79 presented a microbiological detection (41.8%) and 122 allowed to modify the medical behavior (64.6%). Severe complications were observed within 12 hours after the procedure in11 cases (5.8%). In-hospital mortality was 16,8% (N = 21/125). The value of blood neutrophils prior to bronchoalveolar lavage (p = 0.037) and the presence of pulmonary nodules as the predominant tomographic lesion (p = 0.029) were independently associated with global microbiological detection. CONCLUSION: Our research supports the performance of BAL as a diagnostic tool in bone marrow transplant patients with lung opacities.

ABSTRACT

INTRODUCCIÓN: La resistencia a fármacos antituberculosos está influenciada por las características personales y las condiciones de salud de países en vías de desarrollo. OBJETIVO: Determinar los factores asociados a TB-pre extensamente resistente (TB-PRE XDR) en pacientes del Hospital Nacional Dos de Mayo (HNDM) entre 2017 y 2019. PACIENTES Y MÉTODO: Se desarrolló un estudio caso control no pareado, definiendo como caso al paciente con TB- PRE XDR y como control al paciente con TB-S. Se recolectaron variables epidemiológicas, clínicas y radiológicas. RESULTADOS: Se analizaron 51 casos y 102 controles. El análisis bivariado determinó como factores con p 51 años (OR: 0,17, IC95%: 0,05-0,51), uso de drogas (OR:2,5, IC95%: 1,1-5,4), antecedente de TB (OR: 20, IC95%: 8,4-47), reclusión previa (OR: 8, IC95%: 2,7-23,8), infección por VIH (OR: 0,2, IC95%: 0,08-1) y uso previo de fármacos antituberculosos (OR: 21, IC95%: 8,8-50). El análisis de regresión logística identificó como factores asociados a TB-PRE XDR al contacto de TB, antecedente de TB, tiempo de enfermedad y uso previo de fármacos antituberculosos. CONCLUSIÓN: Las medidas para limitar el desarrollo de TB-PRE XDR en pacientes con TB-S deben incidir sobre el antecedente de TB, contacto con TB, tiempo de enfermedad y uso previo de anti-TB no controlados; sin embargo, existen resultados no concluyentes sobre el hábito nocivo y la comorbilidad, siendo necesario más estudios para determinar su influencia como factores asociados identificables.


BACKGROUND: Resistance to anti-TB drugs is influenced by personal characteristics and health conditions in developing countries. AIM: To determine the factors associated with pre-extensively drug-resistant tuberculosis (PRE XDR-TB) at Hospital Nacional Dos de Mayo (HNDM) in patients between the 2017 and 2019. METHODS: An unpaired case control study was developed; defining as case PRE XDR-TB patient and as control S-TB patient. Epidemiological, clinical and radiological variables were collected. RESULTS: We analyzed 51 cases and 102 controls. The bivariate analysis showed as factors with p 51 years (OR: 0.17, 95% CI: 0.05-0.51), drug use (OR: 2.5, 95% CI: 1.1-5.4), previous history of TB (OR: 20, 95% CI: 8.4-47), previous confinement (OR: 8, 95% CI: 2.7-23.8), HIV infection (OR: 0.2, 95% CI: 0.08-1) and previous use of antiTB drugs (OR: 21, 95% CI: 8.8-50). The logistic regression analysis identified as associated factors with PRE XDR-TB the previous contact with TB, a history of TB, length of illness and previous use of tuberculosis antibiotics. CONCLUSION: The measures to limit the development of TB-PRE XDR in patients with TB-S must include the previous history of TB, TB contact, length of illness and previous use of uncontrolled antibiotics against TB; however, there are inconclusive results about the harmful habits and comorbidity, requiring more studies to determine their influence as identifiable associated factors.

ABSTRACT

Introducción: Los factores reproductivos se asocian con cáncer de mama. Actualmente se estudia el comportamiento según subtipos moleculares. Objetivo: Establecer la prevalencia de estos subtipos y su asociación con factores reproductivos en mujeres atendidas en centros del nororiente colombiano. Método: Estudio observacional de corte transversal, en mujeres con cáncer de mama subtipos luminales y HER2 durante 2012-2021. Se indagaron variables sociodemográficas, factores reproductivos y estadio tumoral. Resultados: En total, 347 pacientes cumplieron criterios de elegibilidad, correspondiendo a luminal A el 49,8% (intervalo de confianza del 95% [IC95%]: 44,5-55,1), a luminal B el 29,1% (IC95%: 24,3-33,9) y a HER2 el 15,5% (IC95%: 11,7-19,4). Las mujeres con tumores de mama luminal B tenían más riesgo de tener estadios localmente avanzados (odds ratio [OR]: 1,83; IC95%: 1,11-3,01; p = 0,02). Agrupando los subtipos luminales frente a HER2 se encontró que el 40,72% de las pacientes con subtipos luminales no habían lactado, frente al 69,71% con HER2 (diferencia estadísticamente significativa a favor de luminal A; OR: 1,91; IC95%: 1,02-3,53; p = 0,041). Conclusiones: La prevalencia de tumores luminales es del 84,5%. Existe asociación diferencial entre el antecedente de lactancia materna y la aparición de subtipos luminales, es decir, las mujeres que no lactaron se corresponden con mayor frecuencia con HER2. No se estableció asociación con otros factores estudiados.


Introduction: Stimulus-estrogenic factors are associated with breast cancer. Currently, the behavior according to molecular subtypes is being studied. Objective: To establish the prevalence of these subtypes and their association with reproductive factors in women attended in centers in northeastern Colombia. Method: Observational cross-sectional study in women with breast cancer subtypes luminal and HER2 during 2012 -2021. Sociodemographic variables, stimulus-estrogenic factors and tumor stage were investigated. Results: In total, 347 patients met eligibility criteria, corresponding to luminal A 49.8% (95% confidence interval [95%CI]: 44.5-55.1), luminal B 29.1% (95%CI: 24.3-33.9) and HER2 15.5% (95%CI: 11.7-19.4). Women with luminal B breast tumors were at higher risk of having locally advanced stages (odds ratio [OR]: 1.83; 95%CI: 1.11-3.01; p = 0.02). Grouping the luminal subtypes versus HER2 showed that 40.72% of patients with luminal subtypes had not lactated, compared to 69.71% HER2 (statistically significant difference in favor of luminal A; OR: 1.91; 95%CI: 1.02-3.53; p = 0.041). Conclusions: The prevalence of luminal tumors is 84.5%. There is a differential association between the history of breastfeeding and the appearance of luminal subtypes, i.e., women who did not breastfeed are more likely to have HER2. No association was established with other factors studied.

ABSTRACT

SUMMARY: Athletes differ among themselves and one of the main differences is observed in relation to body shape and composition. Achieving top sports performance requires more standardization in the processes of training and development of a unique methodology for individualizing the control specific adaptation of athletes. The aim of this study is to establish reference data for the most sensitive variables to define the amount and structure of body fat in female athletes in individual sports. The sample included 895 females, divided in: a control group (Cont) of young females (N = 688); International (N = 113), and National level female athletes (N = 94) in 13 individual sports. Four variables described the structureof of body fat: Percentage of body fat (PBF), Body Fat Mass Index (BFMI), Protein Fat Index (PFI) and Index of Body Composition (IBC). Results showed that considering the control group, female athletes have all examined Body Fat variables statistically significantly different (BFMI and PBF are lower, p = 0.011 and p = 0.000, while PFI and IBC are higher, p = 0.000, respectively). Female athletes are also statistically significantly different in relation to the level of competition (p = 0.000), and the investigated variables are responsible for 17.7 % of the variability of the difference between the groups. Competitively more successful female athletes have higher IBC (lower percentage of fat per overall body volume, p = 0.013), as well as, a statistically significantly higher protein mass in relation to body fat mass (PFI, p = 0.018). The most sensitive variables for defining body fat differences between the examined individual sports were IBC, with an influence of 37.9 %, then PFI (32.4 %), then PBF (22.8 %), and finally BFMI, with an influence of 11.4 % on the differences. Based on the results of this study, IBC and PFI are variables that have shown useful scientific-methodological potential for research in the future.


Los deportistas difieren entre sí y una de las principales diferencias se observa en relación a la forma y composición corporal. Alcanzar el máximo rendimiento deportivo requiere una mayor estandarización en los procesos de entrenamiento y en el desarrollo de una metodología única para individualizar el control de adaptación específico de los atletas. El objetivo de este estudio fue establecer datos de referencia de las variables más sensibles para definir la cantidad y estructura de la grasa corporal en mujeres deportistas en deportes individuales. La muestra estuvo compuesta por 895 mujeres, divididas en: un grupo control (Cont) de mujeres jóvenes (N = 688); Atletas femeninas de nivel internacional (N = 113) y nacional (N = 94) en 13 deportes individuales. Cuatro variables describieron la estructura de la grasa corporal: Porcentaje de grasa corporal (PBF), Índice de Masa Grasa Corporal (BFMI), Índice de Proteína Grasa (PFI) e Índice de Composición Corporal (IBC). Los resultados mostraron que, considerando el grupo control, todas las atletas tuvieron diferecias estadísticamente significativas respecto a las variables de grasa corporal (BFMI y PBF son más bajos, p = 0,011 y p = 0,000, mientras que PFI e IBC son más altos, p = 0,000, respectivamente). En relación al nivel de competencia, las atletas femeninas presentan diferencias estadísticamente significativas (p = 0,000), y las variables investigadas son responsables por el 17,7 % de la variabilidad de la diferencia entre los grupos. Las atletas femeninas competitivamente más exitosas tienen un IBC más alto (menor porcentaje de grasa por volumen corporal total, p = 0,013), así como una masa proteica estadísticamente más alta en relación con la masa de grasa corporal (PFI, p = 0,018). Las variables más sensibles para definir las diferencias de grasa corporal entre los deportes individuales examinados fueron IBC, con una influencia del 37,9 %, luego PFI (32,4 %), a seguir PBF (22,8 %) y finalmente BFMI, con una influencia del 11,4 % en las diferencias. En base a los resultados de este estudio, IBC y PFI son las variables que han mostrado un potencial científico-metodológico útil para la investigación en el futuro.

Introduction:SystemicArterial Hypertension is a chronic disease that affects most Brazilian older adults and is one of the main causes of premature deaths and functional disabilities that cause cardiovascular and brain complications. Obesityis among the several predisposing factorsassociatedwithhypertension. Objective:To evaluate the association between SAHand anthropometric indicators in older adultsof the Brazuca Natal study.Methodology: Cross-sectional population-based study with 191 older adults in the city of Natal-RN.Sociodemographic, economic and anthropometric data (weight, height, waist circumference,and hip circumference),Body Mass Index, Waist-Height Ratio and Waist-Hip Ratio were collected. Hypertension was self-reported. Data were analyzed using the SPSS software, version 20.0. The Student's t-test was used to compare themeans of the variables according to sexand presence of hypertension. The association between the presence of the disease and the variables wasperformed by Poisson regression, with crude and adjusted prevalence ratios and respectiveconfidence intervals (95%).Results:The majority of the elderly were female (55%), with a mean age of 69.48 years (SD = 7.38) andBody Mass Indexof 28.46 (SD = 5.25), 59.4% were overweight and 60.1% had hypertension. Mean Body Mass Index, hip circumference and Waist-Height Ratiovalues were higher in women (p<0.05). The age and anthropometric indicators values were higher among the older adults with hypertension (p<0.05). We found that the presence of hypertension was associated with body weight and Body Mass Index,in the crude model and only with body weight in the adjusted model. Conclusions:Anthropometric indicators of easy application and lowcost such as waist circumference can be efficient todetect hypertension in older adults (AU).

ABSTRACT

Introdução: A lei de cotas (nº 12.711/2012) foi criada com o intuito de oportunizar o acesso de alunos oriundos de escolas públicas ao ensino superior. Desde então, medidas adicionais foram tomadas para garantir, não só o acesso, mas a permanência destes alunos nas universidades. Objetivo: Este estudo teve como objetivo avaliar o desempenho acadêmico dealunos cotistas e não cotistas da Faculdade de Odontologia da Universidade Federal do Pará. Metodologia: Foram coletados dados de alunos matriculados nos anos de 2020 e2021 por meio de um questionário on-line e realizada a análise de histórico acadêmico dos voluntários. A análise dos dados foi realizada com software Jamovi versão 1.6.23, utilizando os testesQui-quadrado, t de Student para amostras independentes e análise de regressão linear multivariada. Em todas as análises foi adotado o nível de significância de 0,05. Resultados: Com uma taxa de resposta de 39,92% (n=200), os resultados demonstraram haver um melhor desempenho acadêmico para o grupo não-cotista no que se refere ao Coeficiente de Rendimento Geral (p=0,001). Além disso, alunos do grupo cotista enfrentam mais dificuldades quando comparados aos não-cotistas (p<0,0001). Na análise múltipla verificou-se que juntas, forma de ingresso (cotista ou não), o enfrentamento de dificuldades, recebimento de auxílios e atividades fora da Faculdade explicam quase 10% da variável Coeficiente de Rendimento Geral (R² = 0,098). Conclusões: A complexidade da comparação sugere a possibilidade de múltiplas causas, entre elas o fator socioeconômico e outras dificuldades experienciadas. Entender e atuar nestas causas é de fundamental importância para a construção de uma universidade inclusiva de qualidade (AU).


Introduction:The quota law (nº 12.711/2012) was created with the objective of providing opportunities for students from public schools to enter federal universities. Since then, additional measures have been taken to ensure not only the access, but the permanence of these students in universities. Objectives:This study aimed to assess the academic performance of quota students and non-quota students at the Faculty of Dentistry of the Federal University of Pará. Methods:Data were collected from students enrolled in the years 2020 and 2021 through an online questionnaire and the academic history of the volunteers was analyzed. Data analysis was performed with Jamovi software version 1.6.23, using the chi-square test, Student's t test for independent samples, and multivariate linear regression analysis. In all analyses, a significance level of 0.05 was adopted. Results:With a response rate of 39.92% (n=200), the results showed a better academic performance for the non-quotastudents with regard to the General PerformanceCoefficient (p=0.001). In addition, quota students face more difficulties when compared to non-quota students (p<0.0001). In the multiple analysis, it was found that the admission modality (quota students or non-quota students), facing difficulties, receiving aid, and activities outside the University explained together almost 10% of the General Performance Coefficient variable (R² = 0.098). Conclusion:The complexity of the comparison suggests the possibility of multiple causes, including the socioeconomic factor and other difficulties experienced. Understanding and acting on these causes is of fundamental importance for the construction of a quality inclusive university (AU).

ABSTRACT

ABSTRACT Objective: To identify the association between individual and socioeconomic factors during the first thousand days of the child's life and the occurrence of risk behaviors for the development of malocclusions. Material and Methods: Cross-sectional study. A sample of 655 6-year-old schoolchildren and families was included. Interviews with mothers were performed at home. The dependent variables were risk behaviors to the development of malocclusions. Independent variables were socioeconomic conditions, aspects of gestation, birth and health of the child up to two years of age. Bivariate and multivariate analyzes were performed through Poisson regression. Results: Maternal education of less than eight years was independently associated with the interruption of exclusive breastfeeding until the fourth month (PR=1.58 CI 95%; 1.07; 2.37). Occupation of the mother with income [PR=1.26; 1.02; 1.56)], occupation of the father without income [PR=1.46 (1.01; 2.14)] were associated fwith interruption of breastfeeding until the sixth month. Pregnancy in adolescence [PR=0.83 (0.70; 0.98)] and nursery attendance [PR=1.15 (1.02; 1.28)] were associated with bottle use. Nursery attendance [PR=1.27 (1.01; 1.59)], hospitalization in the first 29 days of life [PR=1.34 (1.01; 1.80)], occurrence of reflux [PR=1.30 (1.01; 1.70)] were associated with pacifier using. Conclusion: Variables related to the period of the first thousand days of life are associated with higher risk behaviors for the occurrence of malocclusions.

Participaram deste estudo 674 estudantes universitários, com idade variando entre 18 e 62 anos (M= 23,18, DP= 5,81). Seis modelos fatoriais unidimensionais foram testados com o objetivo de identificar a solução mais parcimoniosa para o instrumento. Sugere-se uma solução final com quatro itens, ao invés de seis. Análises de TRI foram realizadas e observou-se alta fidedignidade da escala para mensuração de baixos níveis do traço latente. A ESEC esteve significativamente correlacionada com os cinco fatores de personalidade, adaptabilidade de carreira e satisfação com a vida. Indica-se que a ESEC apresenta evidências de validade favoráveis ao seu uso no contexto brasileiro, mas o instrumento identifica melhor indivíduos insatisfeitos com a escolha do curso do que os satisfeitos.

This study aimed to adapt and obtain validity evidence for the Academic Major Satisfaction Scale (AMSS) in the Brazilian context. The instrument was tested in 674 college students, with ages ranging from 18 to 62 (M = 23.18, SD = 5.81). Six unidimensional models were tested in order to find the parsimonious solution to the instrument. A four-item final solution is suggested, instead of the original 6-item solution. IRT was applied and it was identified that the AMSS had high reliability in individuals with low levels of latent trait. AMSS was significantly correlated with the big-five personality factors, career adapt-ability and life satisfaction. AMSS presents favorable evidences of validity to the Brazilian context, although the scale is more efficient in identifying students who are unsatisfied rather than satisfied with their college major.

Este estudio buscó adaptar y obtener evidencia de la validez de la Escala de Satisfacción de Elección de Curso (ESEC) para su uso en el contexto brasileño. Participaron un total de 674 estudiantes universitarios, con edades comprendidas entre los 18 y los 62 años (M = 23,18, DT = 5,81). Se probaron seis modelos factoriales unidimensionales con el fin de identificar la solución más parsimoniosa para el instrumento. Se sugiere una solución final con cuatro elementos en lugar de seis. El modelo de respuesta graduada se aplicó a los ítems que funcionaron bien a niveles bajos del constructo. La ESEC se correlacionó significativamente con los cinco factores de personalidad, adaptabilidad profesional y satisfacción con la vida. Se indica que la ESEC presenta evidencia de validez favorable a su uso en el contexto brasileño, pero el instrumento identifica mejor a los insatisfechos con la elección del curso que a los satisfechos.

ABSTRACT

This study aimed to evaluate social support and marital relationships in women with and without postpartum depression (PND), investigating the relationship between these constructs and the positive and negative impacts of each of them for the PND. A cross-sectional study was conducted with 67 women (32 with depression and 35 without depression) with children aged between 51 and 77 days. The results indicated that women with PND (assessed through the EPDS) had lower scores in perception of social support and identified their marital relationships as more conflicting. In the hierarchical model, demographic variables (baby's age and maternal education) and marital relationship explained part of the variance of symptoms of PND. Social support did not prove to be a significant predictor in the model. Among the factors evaluated, the quality of the marital relationship was the most important to minimize the risk of developing PND, being an aspect subject to interventions by health professionals.

O objetivo foi avaliar o apoio social e o relacionamento conjugal em mulheres com e sem depressão pós-parto (DPP), investigando a relação entre esses construtos e os impactos positivos e negativos de cada um deles para a DPP. Conduziu-se um estudo transversal com 67 mulheres (32 com depressão e 35 sem depressão) com filhos com idade entre 51 e 77 dias. Os resultados indicaram que mulheres com DPP (avaliadas por meio da EPDS) relataram menor percepção de apoio social e identificaram seus relacionamentos conjugais como mais conflituosos. No modelo hierárquico, variáveis demográficas (idade do bebê e escolaridade materna) e relacionamento conjugal explicaram em parte a variância dos sintomas de DPP. O apoio social não se revelou um preditor significativo no modelo. Entre os avaliados, a qualidade do relacionamento conjugal foi o mais importante para minimizar o risco de desenvolvimento de DPP, sendo um aspecto passível de intervenções por profissionais da saúde.

ABSTRACT

Abstract Objective: To present the profile of hospitalizations due to transport accidents in individuals aged 0-19 years in a reference hospital for urgent and emergency traumatology care. Material and Methods: This retrospective study is grounded on analyzing medical records of children and adolescents hospitalized due to transport accidents in 2016 and 2017. The bivariate analyses included Chi-square and Fischer's exact tests and binary logistic regression, with a 5% significance level. Results: Four hundred and seventy-five (43.7%) of the 1,088 medical records investigated corresponded to transport accidents, and accidents involving motorcycles were the most frequent (68.3%), affecting adolescents (81.3%), while children were more involved in accidents as pedestrians (57.1%). Advancing age increases the likelihood of the outcome, with a significant association in the multivariate analysis (p<0.001). The mandible was most frequently affected in maxillofacial fractures. Conclusion: Transport accidents predominantly affect male adolescents, involving motorcycles, and the lower limbs are the most affected. The mandible was the most affected bone in maxillofacial fractures.
