ABSTRACT

This study had as general objective to characterize and associate social skills, behavior problems, and academic competence of students with intellectual disabilities in school inclusion and; as specific objectives to verify predictive values for social skills and differences between groups diagnosed with intellectual disability and other associated diagnoses. This was a quantitative, cross-sectional, descriptive, correlational, predictive, and comparative study. Forty-four students with intellectual disability participated (11 of them presented other associated diagnoses), who were evaluated by 42 guardians and 34 teachers. The instruments used were Social Skills Rating System (SSRS-BR) and the Parental Educative Social Skills Interview Script (RE-HSE-P). The evaluation from guardians and teachers were different. Social skills were negatively associated with behavior problems and positively associated with academic competence; behavior problems and diagnosis were negative predictors to social skills. There were significant differences in the groups. The results highlight the importance of intervention programs to develop social skills.(AU)

ABSTRACT

SUMMARY: Measurements of the upper strait of the pelvis can be calculated using the Anterior Pelvic Index. The objective of the study was to determine the external validity and cut-off point of the API, to classify narrow pelvises from normal ones. We selected 214 women from 15 to 55 years old, 171 had vaginal delivery and 43 by caesarean section by feto-pelvic disproportion (FPD) of maternal origin, in whom the API was calculated, of which its mean difference was established with an alpha error of <0.05. Maximum values of sensitivity and specificity, ROC curve and Youden index were determined. The student's t gave a p-value =0.000 of the mean difference between the women who had vaginal delivery and those who had cesarean section by FPD of maternal origin; the value of the area under the ROC curve was 0.758 (CI 95% 0.695 - 0.814) with a p-value=0.0001. Maximum sensitivity was 74.42 % (CI 95%: 58.8 % to 86.5 %) and maximum specificity was 73.10 % (CI 95%: 65.8 % to 79.6 %), produced a Youden index of 0.475 (CI 95% 0.283 - 0.590) which is associated with the 15.44 (CI 95% 14.19 - 15.83) of the API scale. The API is a good tool for predicting women with suspected narrow pelvis and allows its classification into three types of pelvises: an API value of more than 15.83 would indicate pelvis suitable for vaginal delivery; an API value between 14.19 and 15.83 would be suspected of pelvic narrowness; an API value less than 14.19 would confirm a narrow pelvis.


Las medidas del estrecho superior de la pelvis pueden calcularse mediante el Índice Pelviano Anterior. El objetivo del estudio fue determinar la validez externa y el punto de corte del API, para clasificar pelvis estrechas de las normales. Seleccionamos 214 mujeres de 15 a 55 años, 171 tuvieron parto vaginal y 43 mediante cesárea por DFP de origen materno, en quienes se calculó el API, del cual se estableció su diferencia de medias con un error alfa de <0,05. Se determinaron valores máximos de sensibilidad y especificidad, curva ROC e índice de Youden. La t de Student dio un p-valor=0,000 de la diferencia de medias entre las mujeres de tuvieron parto vaginal y las que fueron sometidas a cesárea por DFP de origen materno; el valor del área bajo la curva ROC fue 0,758 (IC 95% 0,695 - 0,814) con un p- valor=0,0001. La máxima sensibilidad (74,42 %. IC 95%: 58,8 % a 86,5 %) y máxima especificidad (73,10 %. IC 95%: 65,8 % a 79,6 %), produjeron un índice de Youden de 0,475 (IC 95% 0,283 - 0,590) el cual está asociado al valor 15,44 (IC 95% 14,19 - 15,83) de la escala del API. El API es una buena herramienta de predicción de mujeres con sospecha de pelvis estrecha y permite su clasificación en tres tipos de pelvis: un valor de API de mas de 15,83 indicaría pelvis aptas para un parto vaginal; un valor de API entre 14,19 y 15,83 se sospecharía de estrechez pélvica; un valor de API menor a 14,19 confirmaría una pelvis estrecha.

ABSTRACT

Objetivo: Avaliar o valor preditivo da colonização prévia por Acinetobacter baumannii (CRAB) e Pseudomonas aeruginosa (CRPA) resistente a carbapenêmicos estabelecida em culturas de vigilância para infecção subsequente por esses patógenos em pacientes internados em UTI. Métodos: Foi realizado um estudo de coorte com pacientes internados na unidade de terapia intensiva por pelo menos 48 h. Foram medidos os valores preditivos negativos e positivos, sensibilidade e especificidade das culturas de vigilância em CRAB e CRPA. Resultados: Foram incluídos 693 pacientes infectados. Pacientes previamente colonizados por CRAB e CRPA tiveram maior probabilidade de serem infectados por esses patógenos: OR ajustado: 10,34 (6,58 - 16,45; p < 0,001) e 2,30 (3,88 - 10,26; p < 0,001), respectivamente. Encontramos altos valores preditivos negativos de culturas de vigilância para CRAB (87,18%) e CRPA (88,30%) e alta especificidade 91,96% e 90,13%, respectivamente. Conclusões: Pacientes não colonizados por CRAB e CRPA mostraram-se menos propensos à infecção por esses patógenos. Esses achados podem contribuir para a escolha da terapia antimicrobiana empírica e desencorajar a prescrição de antibióticos contra esses patógenos em pacientes sem colonização prévia.


Objective: To assess the predictive value of prior carbapenem-resistant Acinetobacter baumannii (CRAB) and Pseudomonas aeruginosa (CRPA) colonization established in surveillance cultures for subsequent infection by these pathogens in ICU patients. Methods: A cohort study was performed with patients admitted to the intensive care unit for at least 48 h. Negative and positive predictive values, sensitivity, and specificity of surveillance cultures in CRAB and CRPA were measured. Results: 693 infected patients were included. Patients previously colonized by CRAB and CRPA were more likely to be infected by these pathogens: adjusted OR: 10.34 (6.58 - 16.45; p < 0.001) and 2.30 (3.88 - 10.26; p < 0.001), respectively. We found high negative predictive values of surveillance cultures for CRAB (87.18%) and CRPA (88.30%) and high specificity 91.96% and 90.13%, respectively. Conclusions: Patients not colonized by CRAB and CRPA were less prone to infection by these pathogens. These findings may contribute to the choice of empirical antimicrobial therapy and discourage the prescription of antibiotics against these pathogens in patients without previous colonization.

ABSTRACT

Introducción: El índice de irresecabilidad valora la presencia de cuatro variables (masa abdominal palpable, tumor en fondo de saco de Douglas, presencia de líquido ascítico, valor preoperatorio de Ca 125 mayor a 1000 U/ml); previo a la realización de una cirugía citorreductora primaria en pacientes con cáncer de ovario. El objetivo del presente estudio fue realizar una prueba diagnóstica del índice de irresecabilidad con la decisión de realizar citorreducción óptima en pacientes con cáncer de ovario que fueron operadas en un hospital público de referencia nacional en Ecuador en 3 años de estudio. Metodología: En el presente estudio de pruebas diagnósticas, se estudiaron mujeres operadas con cáncer de ovario, en el Hospital de Especialidades Eugenio Espejo (Ecuador) de septiembre del 2016 a septiembre del 2018. Se incluyeron pacientes con citorreducción óptima y subóptima. Se presenta un análisis descriptivo con frecuencias, porcentajes y promedios. Se evaluó la sensibilidad, especificidad, valor predictivo negativo (VPN) y valor predictivo positivo (VPP) del índice de irresecabilidad comparado con la citorreducción. Resultados: Fueron 148 casos analizados. La especificidad del índice fue de 81 %, con un valor predictivo (VP) positivo del 77 % y VP negativo de 68 %. La sensibilidad de la ascitis 85 % y la masa abdominal palpable del 79 %. En las pacientes que presentaron valores de antígeno CA-125 menor a 1000 U/ml, el riesgo de obtener una citorreducción óptima fue OR: 0.15 (IC95% 0.069 ­ 0.307; P: 0.0001); las pacientes que presentaron valores del índice de irresecabilidad entre 1 y 2 puntos versus 3 y 4 fue de OR: 7.04 (IC95% 3.33 -14.87, P: 0.0001). Conclusiones: El Índice de irresecabilidad presentó una capacidad estadísticamente significativa para predecir citorreducción óptima en las pacientes con cáncer ovario operadas en el Hospital de Especialidades Eugenio Espejo.


Introduction: The unresectability index assesses the presence of four variables (palpable abdominal mass, tumor in the fornix of Douglas, presence of ascitic fluid, preoperative Ca 125 value greater than 1000 U/ml); before performing primary cytoreductive surgery in patients with ovarian cancer. The objective of this study was to carry out a diagnostic test of the unresectability index with the decision to perform optimal cytoreduction in patients with ovarian cancer who underwent surgery in a public hospital of national reference in Ecuador in 3 years of study. Methodology: In the present study of diagnostic tests, women operated on for ovarian cancer were studied at the Eugenio Espejo Specialties Hospital (Ecuador) from September 2016 to September 2018. Patients with optimal and suboptimal cytoreduction were included. A descriptive analysis with frequencies, percentages, and averages is presented. The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of the unresectable index compared with cytoreduction were evaluated. Results: 148 cases were analyzed. The specificity of the index was 81%, with a positive predictive value (PV) of 77% and a negative PV of 68%. The sensitivity of ascites is 85%, and the palpable abdominal mass of 79%. In patients who presented CA-125 antigen values less than 1000 U/ml, the risk of obtaining optimal cytoreduction was OR: 0.15 (95% CI 0.069 - 0.307; P: 0.0001); The patients who presented unresectability index values between 1 and 2 points versus 3 and 4 were OR: 7.04 (95% CI 3.33 -14.87, P: 0.0001). Conclusions: The unresectability index presented a statistically significant capacity to predict optimal cytoreduction in patients with ovarian cancer operated on at the Eugenio Espejo Specialties Hospital.

ABSTRACT

Objetivo: Validar la técnica de ganglio centinela utilizando verde de indocianina en la estadificación del cáncer de endometrio. Método: Realizamos un estudio prospectivo entre enero y diciembre de 2021. Se incluyeron todas las pacientes portadoras de cáncer de endometrio clínicamente en etapa 1, de todos los grados de diferenciación e histologías. Todas las pacientes fueron sometidas a una estadificación laparoscópica. Se inició el procedimiento con identificación de ganglio centinela utilizando verde de indocianina. Posteriormente, se completó la cirugía de estadiaje estándar en todas las pacientes. Los ganglios centinelas fueron procesados con técnica de ultraestadiaje. Resultados: Se incluyeron 33 pacientes. El 81% presentaron histología endometrioide. El 100% fueron sometida además a una linfadenectomía pelviana estándar y el 20% a una linfadenectomía paraaórtica simultáneamente. Se detectó al menos un ganglio centinela en el 100% de los casos. La detección bilateral ocurrió en el 90,9%. La localización más frecuente fue la fosa obturatriz y la arteria hipogástrica. Obtuvimos una sensibilidad del 90% para detectar enfermedad ganglionar y un valor predictivo negativo del 95,8%. Conclusiones: La técnica de ganglio centinela utilizando verde de indocianina es replicable. Los resultados de nuestra serie nos permiten realizar procedimientos menos agresivos al estadificar el cáncer de endometrio.


Objective: To validate sentinel node mapping using indocyanine green in endometrial cancer staging. Method: A prospective study was conducted between January and December 2021. All patients with clinically stage 1 endometrial cancer, of all grades and histologies were included. All patients underwent laparoscopic staging. The procedure began with identification of the sentinel node using indocyanine green. Subsequently, standard staging surgery was completed in all patients. Sentinel nodes were processed using ultrastaging technique. Results: Thirty-three patients were enrolled. 81% of cases had endometrioid histology. All patients also underwent a standard pelvic lymphadenectomy and in 20% of cases a para-aortic lymphadenectomy. At least one sentinel node was detected in 100% of the cases. Bilateral detection occurred in 90.9%. The most frequent location was obturator fossa and hypogastric artery. Sensitivity to detect lymph node disease was 90% and negative predictive value 95.8%. Conclusions: Sentinel lymph node mapping using indocyanine green is a replicable technique. Our results allows us to perform less aggressive procedures in endometrial cancer staging.

ABSTRACT

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)


Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

ABSTRACT

Objetivo: Determinar el grupo RhD fetal a través del estudio del gen RHD en ADN fetal que se encuentra libre en plasma de embarazadas RhD negativo. Método: Se analizó la presencia de los genes RHD, SRY y BGLO en ADNfl obtenido de plasma de 51 embarazadas RhD negativo no sensibilizadas, utilizando una qPCR. Los resultados del estudio genético del gen RHD se compararon con el estudio del grupo sanguíneo RhD realizado por método serológico en muestras de sangre de cordón, y los resultados del estudio del gen SRY fueron cotejados con el sexo fetal determinado por ecografía. Se calcularon la sensibilidad, la especificidad, los valores predictivos y la capacidad discriminativa del método estandarizado. Resultados: El gen RHD estaba presente en el 72,5% de las muestras y el gen SRY en el 55,5%, coincidiendo en un 100% con los resultados del grupo RhD detectado en sangre de cordón y con el sexo fetal confirmado por ecografía, respectivamente. Conclusiones: Fue posible deducir el grupo sanguíneo RhD del feto mediante el estudio del ADN fetal que se encuentra libre en el plasma de embarazadas con un método molecular no invasivo desarrollado y validado para este fin. Este test no invasivo puede ser utilizado para tomar la decisión de administrar inmunoglobulina anti-D solo a embarazadas RhD negativo que portan un feto RhD positivo.


Objective: To determine the fetal RhD group through the study of the RHD gene in fetal DNA found free in plasma of RhD negative pregnant women. Method: The presence of the RHD, SRY and BGLO genes in fetal DNA obtained from plasma of 51 non-sensitized RhD negative pregnant women was analyzed using qPCR. The results of the genetic study of the RHD gene were compared with the RhD blood group study performed by serological method in cord blood samples, and the results of the SRY gene study were compared with the fetal sex determined by ultrasound. Sensitivity, specificity, predictive values and discriminative capacity of the standardized method were calculated. Results: The RHD gene was present in 72.5% of the samples and the SRY gene in 55.5%, coinciding 100% with the results of the RhD group detected in cord blood, and with the fetal sex confirmed by ultrasound, respectively. Conclusions: It was possible to deduce the RhD blood group of the fetus through the study of fetal DNA found free in the plasma of pregnant women with a non-invasive molecular method developed and validated for this purpose. This non-invasive test can be used to make the decision to administer anti-D immunoglobulin only to RhD-negative pregnant women carrying an RhD-positive fetus.

ABSTRACT

Abstract Introduction Plasma transfusion is a common therapeutic strategy used to lower international normalized ratio (INR) values in the non-emergent setting. However, due to lack of evidence of its efficacy, standardized guidelines for this practice have not been well established. Methods This retrospective observational cohort study analyzed 276 inpatient encounters that involved plasma transfusions focusing on change in INR values from pre- to post-transfusion, with respect to the following predictor variables: vitamin K co-administration, number of plasma units transfused, order indication and body mass index (BMI). Results The overall average change in the INR was 1.35. Patients who received vitamin K showed an average change of 2.51, while patients that did not receive vitamin K demonstrated an average change of 0.70. Increased numbers of plasma units transfused showed benefit up to three-unit orders. Greater decreases in the INR were observed for patients requiring plasma for anticoagulation reversal or active bleeding. There was no significant difference in the change in INR based on the BMI. By multivariate and regression analyses, the stepwise addition of each successive predictor variable demonstrated an increase in the shared variance in the outcome of the post-transfusion INR: the pre-transfusion INR and vitamin K co-administration alone was not significant (p= 0.45); the additional number of plasma units transfused was significant (R² = 0.13, p < 0.001), and; the subsequent additional plasma order indications (R² = 0.19, p < 0.001) and BMI (R² = 0.18, p < 0.001) were increasingly significant. Conclusion Taking into consideration the combination of multiple predictive factors may aid in a more efficient use of plasma products.

ABSTRACT

Introducción. La detección precoz de los trastornos del desarrollo permite aplicar acciones que mejoren su evolución y pronóstico. En nuestro país, la Prueba Nacional de Pesquisa (PRUNAPE) requiere de un profesional certificado. El Instrumento de Observación del Desarrollo Infantil (IODI) es una herramienta de vigilancia sistematizada del desarrollo que no requiere especialización para su aplicación. La utilización del IODI como herramienta de evaluación del neurodesarrollo sería de utilidad por su fácil aplicabilidad. Objetivo. Evaluar el desempeño del IODI como prueba de vigilancia de trastornos del desarrollo utilizando la PRUNAPE como patrón de oro. Población y métodos. Estudio prospectivo analítico de prueba diagnóstica. Se incluyeron de forma aleatoria pacientes de 1 mes a 4 años, cuyos padres dieron el consentimiento para participar. Se evaluó el desempeño del IODI usando la PRUNAPE como patrón de oro. Se estimaron los valores de clivaje de sensibilidad (S), especificidad (E), valores predictivos positivo y negativo (VPP y VPN), y las razones de verosimilitud positiva y negativa (RVP y RVN, respectivamente). Resultados. Se evaluaron 91 pacientes; 24 no pasaron la PRUNAPE, de los cuales 21 tampoco pasaron el IODI (sensibilidad: 87,5 %; especificidad: 79,1 %; valor predictivo positivo: 60,1 %; valor predictivo negativo: 94,6 %). Razón de verosimilitud positiva: 4,2; negativa: 0,2. Conclusión. El IODI mostró un desempeño aceptable como prueba de vigilancia de trastornos del desarrollo en comparación con la PRUNAPE.


Introduction. An early detection of developmental disorders allows to implement actions to improve their course and prognosis. In Argentina, the administration of the National Screening Test (Prueba Nacional de Pesquisa, PRUNAPE) requires a certified professional. The Child Development Observation Instrument (Instrumento de Observación del Desarrollo Infantil, IODI) is a systematized developmental surveillance tool that does not require specialization for its administration. The use of the IODI as a neurodevelopmental assessment tool would be useful because of its easy applicability. Objective. To assess the performance of the IODI as a surveillance test for developmental disorders using the PRUNAPE as a gold standard. Population and methods. Analytical, prospective study with a diagnostic test. Patients aged 1 month to 4 years, whose parents gave consent to participate, were included randomly. The IODI performance was assessed using the PRUNAPE as the gold standard. Sensitivity (S), specificity (Sp), positive and negative predictive values (PPV and NPV), and positive and negative likelihood ratios (PLR and NLR) were estimated. Results. Ninety-one patients were assessed; 24 failed the PRUNAPE, of these, 21 also failed the IODI (S: 87.5%, Sp: 79.1%, PPV: 60.1%, NPV: 94.6%). PLR: 4.2, NLR: 0.2. Conclusion. The IODI showed an acceptable performance as a developmental disorders surveillance test compared to the PRUNAPE.

ABSTRACT

OBJECTIVE@#To quantitatively assess cardiac functions in patients with cardiac amyloidosis (CA) and hypertrophic cardiomyopathy (HCM) using cardiac magnetic resonance-feature tracking (CMR-FT) technique and evaluate the prognostic value of CMR-FT in patients with CA.@*METHODS@#We retrospectively collected the data from 31 CA patients with systemic amyloidosis confirmed by Congo red staining and serum immunohistochemistry after extracardiac tissue biopsy undergoing CMR at our hospital from March, 2013 to June, 2021.Thirty-one age and gender matched patients with asymmetric left ventricular wall hypertrophy and 31 healthy individuals without organic or functional heart disease served as the controls.Radial, circumferential and longitudinal strains and strain rates of the left ventricle at the global level and in each myocardial segment (basal, middle and apical) were obtained with CMR-FT technique and compared among the 3 groups.The predictive value of myocardial strains and strain rates for all-cause mortality in CA patients was analyzed using a stepwise COX regression model.@*RESULTS@#The left ventricular volume, myocardial mass, ejection fraction and cardiac output differed significantly among the groups (P < 0.05).Except for apical longitudinal strain, the global and segmental strains were all significantly lower in CA group than in HCM group (P < 0.05).The global and segmental strains were all significantly lower in CA group than in the healthy individuals (P < 0.05).The basal strain rates in the 3 directions were significantly lower in CA group than in the healthy individuals (P < 0.05), but the difference in apical strain rates was not statistically significant between the two groups.Multivariate stepwise COX analysis showed that troponin T (HR=1.05, 95%CI: 1.01-1.10, P=0.017) and middle peak diastolic circumferential strain rate (HR=6.87, 95%CI: 1.52-31.06, P=0.012) were strong predictors of death in CA patients.@*CONCLUSION@#Strain and strain rate parameters derived from CMR-FT based on cine sequences are new noninvasive imaging markers for assessing cardiac impairment in CA and cardiac function changes in HCM, and provide independent predictive information for all-cause mortality in CA patients.

ABSTRACT

Abstract Background: Predicting difficult direct laryngoscopies remains challenging and improvements are needed in preoperative airway assessment. We conceived two new tests (the upper airway angle and the glottic height) and assessed their association with difficult direct laryngoscopies as well as their predictive performance. Methods: A prospective cohort was conducted with 211 patients undergoing general anesthesia for surgical procedures. We assessed the association between difficult laryngoscopies and modified Mallampati Test (MMT), Upper Lip Bite Test (ULBT), Mandibular Length (ML), Neck Circumference (NC), Mouth Opening (MO), Sternomental Distance (SMD), Thyromental Distance (TMD), Upper Airway Angle (UAA), and Glottic Height (GH). We also estimated their predictive values. Results: Difficult laryngoscopy was presented by 12 patients (5.7%). Six tests were significantly associated with difficult laryngoscopies and their area under the ROC curve, and 95% CIs were as follows: UAA = 88.82 (81.86-95.78); GH = 86.43 (72.67-100); ML = 83.75 (72.77-94.74); NC = 79.17 (64.98-93.36); MO = 65.58 (45.13-86.02); and MMT = 77.89 (68.37-87.41). Conclusion: We have found two new features (the UAA and the GH) to be significantly associated with the occurrence of difficult direct laryngoscopies. They also presented the best predictive performance amongst the nine evaluated tests in our cohort of patients. We cannot ensure, however, these tests to be superior to other regularly used bedside tests based on our estimated 95% CIs.

ABSTRACT

Objective: To investigate the predictive value of glycosylated hemoglobin A1c/apolipoprotein A-1 (HbA1c/ApoA-1) ratio for major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS). Methods: The present study is a retrospective cohort study. ACS patients who were hospitalized and underwent coronary angiography at Beijing Hospital from March 2017 to March 2019 were enrolled. Baseline information such as sex, age, previous history, Gensini score, HbA1c and ApoA-1 were analyzed. Patients were divided into two groups according to presence or absence of MACEs and the difference on HbA1c/ApoA-1 ratio was compared between the two groups. According to the tertiles of HbA1c/ApoA-1 levels, patients were divided into high (5.87-16.12), medium (4.50-5.83) and low (2.11-4.48) HbA1c/ApoA-1 groups. Cox proportional risk model was used to evaluate the differences in MACEs and all-cause mortality among the three groups. Kaplan-Meier survival analysis was used to compare the differences of MACEs between the various HbA1c/ApoA-1 groups. Results: A total of 366 ACS patients were included in this study. The mean age of the patients was (65.9±10.3) years. There were 59 MACEs and 10 all-cause deaths during the mean of (22.3±4.4) months follow-up. After adjusting for age, systolic blood pressure, history of diabetes and Gensini score, the incidence of MACEs was 2.45 times higher in the high HbA1c/ApoA-1 group than in the low HbA1c/ApoA-1 group (95%CI 1.16-5.18, P=0.019). There was no significant difference in all-cause mortality between the high and low HbA1c/ApoA-1 groups (P=1.000). Kaplan-Meier survival analysis showed that patients in the high HbA1c/ApoA-1 group had the highest risk of MACEs, while patients in the low HbA1c/ApoA-1 group had the lowest risk of MACEs (P<0.01). Spearman rank correlation analysis showed that HbA1/ApoA-1 ratio was positively correlated with Gensini score in ACS patients (r=0.274, P<0.01). Conclusion: High HbA1c/ApoA-1 ratio was an independent risk factor for MACEs in ACS patients. Patients with high HbA1c/ApoA-1 ratio had more severe coronary artery disease lesions. HbA1c/ApoA-1 ratio may be used as a potential risk stratification biomarker for ACS patients, it might be useful for the early identification of high-risk population and for predicting the incidence of MACEs among ACS patients.

ABSTRACT

INTRODUCTION@#Creatinine has limitations in identifying and predicting acute kidney injury (AKI). Our study examined the utility of neutrophil gelatinase-associated lipocalin (NGAL) in predicting AKI in patients presenting to the emergency department (ED), and in predicting the need for renal replacement therapy (RRT), occurrence of major adverse cardiac events (MACE) and all-cause mortality at three months post visit.@*METHODS@#This is a single-centre prospective cohort study conducted at Singapore General Hospital (SGH). Patients presenting to SGH ED from July 2011 to August 2012 were recruited. They were aged ≥21 years, with an estimated glomerular filtration rate <60 mL/min/1.73 m2, and had congestive cardiac failure, systemic inflammatory response syndrome or required hospital admission. AKI was diagnosed by researchers blinded to experimental measurements. Serum NGAL was measured as a point-of-care test.@*RESULTS@#A total of 784 patients were enrolled, of whom 107 (13.6%) had AKI. Mean serum NGAL levels were raised (P < 0.001) in patients with AKI (670.0 ± 431.9 ng/dL) compared with patients without AKI (490.3 ± 391.6 ng/dL). The sensitivity and specificity of NGAL levels >490 ng/dL for AKI were 59% (95% confidence interval [CI] 49%-68%) and 65% (95% CI 61%-68%), respectively. Need for RRT increased 21% per 100 ng/dL increase in NGAL (P < 0.001), whereas odds of death in three months increased 10% per 100 ng/dL increase in NGAL (P = 0.028). No clear relationship was observed between NGAL levels and MACE.@*CONCLUSION@#Serum NGAL identifies AKI and predicts three-month mortality.

ABSTRACT

Objective:To study the application value of narrow-band imaging in the diagnosis of laryngopharyngeal reflux. Methods:A total of 275 patients admitted to the inpatient department or laryngoscopy room of the Otolaryngology Head and Neck Surgery Department of the First Affiliated Hospital of Harbin Medical University from September 2022 to April 2023 due to throat discomfort were selected as the research subjects. All of them completed RSI, RFS scoring scales and electronic laryngoscopy(including ordinary white light and NBI). According to the expert consensus of LPRD in 2022, RSI and RFS scoring scale were used as diagnostic criteria to divide them into LPR group and non-LPR group. Chi-square test was used to analyze the differences of positive rates of characteristic manifestations under NBI among different groups. The consistency of NBI and scale diagnostic methods was analyzed by Kappa, and RSI and RFS scoring were used as diagnostic criteria, The diagnostic efficiency of NBI method was analyzed. Results:There were 190 people in the LPR group, 157 of whom showed characteristic performance under the NBI mode, with a positive rate of 82.6%(157/190); there were 85 people in the non-LPR group, with a positive rate of 18.8%(16/85). There was a statistically significant difference in the positive rate between the two groups(χ²=102.47, P<0.05). The consistency rate between RSI, RFS and NBI was 82.2%(226/275). Kappa consistency analysis was used, and Kappa=0.605(P<0.05), indicating good consistency between the two diagnostic methods. Using RSI and RFS as diagnostic criteria for LPR, the sensitivity of NBI diagnostic method was 82.6%(157/190), specificity 81.2%(69/85), positive predictive value 90.8%(157/173) and negative predictive value 67.6%(69/102). Conclusion:Narrow-band imaging, as a new endoscopic imaging technique, can show small changes in mucosal surface micro vessels and play an important role in the diagnosis of laryngopharyngeal reflux.

ABSTRACT

OBJECTIVE@#To investigate the value of T2 mapping in the assessment of myocardial changes and prognosis in patients with acute ST segment elevation myocardial infarction (STEMI).@*METHODS@#A retrospective study was conducted. A total of 30 patients with acute STEMI admitted to Tianjin First Central Hospital from January 2021 to March 2022 were enrolled as the experimental group. At the same time, 30 age- and sex-matched healthy volunteers and outpatients with non-specific chest pain with no abnormalities in cardiac magnetic resonance (CMR) examination were selected as the control group. CMR was performed within 2 weeks after the diagnosis of STEMI, as the initial reference. A plain CMR review was performed 6 months later (chronic myocardial infarction, CMI). Plain scanning includes film sequence (CINE), T2 weighted short tau inversion recovery (T2-STIR), native-T1 mapping, and T2 mapping. Enhanced scanning includes first-pass perfusion, late gadolinium enhancement (LGE), and post-contrast T1 mapping. Quantitative myocardial parameters were compared between the two groups, before and after STEMI myocardial infarction. The receiver operator characteristic curve (ROC curve) was used to evaluate the diagnostic efficacy of native-T1 before myocardial contrast enhancement and T2 values in differentiating STEMI and CMI after 6 months.@*RESULTS@#There were no statistically significant differences in age, gender, heart rate and body mass index (BMI) between the two groups, which were comparable. The native-T1 value, T2 value and extracellular volume (ECV) were significantly higher than those in the control group [native-T1 value (ms): 1 434.5±165.3 vs. 1 237.0±102.5, T2 value (ms): 48.3±15.6 vs. 21.8±13.1, ECV: (39.6±13.8)% vs. (22.8±5.0)%, all P < 0.05]. In the experimental group, 12 patients were re-examined by plain CMR scan 6 months later. After 6 months, the high signal intensity on T2-STIR was still visible, but the range was smaller than that in the acute phase, and the native-T1 and T2 values were significantly lower than those in the acute phase [native-T1 value (ms): 1 271.0±26.9 vs. 1 434.5±165.3, T2 value (ms): 34.2±11.2 vs. 48.3±15.6, both P < 0.05]. ROC curve analysis showed that the area under the ROC curve (AUC) of native-T1 and T2 values in differentiating acute STEMI from CMI was 0.71 and 0.80, respectively. When native-T1 cut-off value was 1 316.0 ms, the specificity was 100% and the sensitivity was 53.3%; when T2 cut-off value was 46.7 ms, the specificity was 100% and the sensitivity was 73.8%.@*CONCLUSIONS@#The T2 mapping is a non-invasive method for the diagnosis of myocardial changes in patients with acute STEMI myocardial infarction, and can be used to to evaluate the clinical prognosis of patients.

ABSTRACT

OBJECTIVE@#To investigate the value of coronary computed tomographic angiography (CCTA)-based fractional flow reserve (CT-FFR) and plaque quantitative analysis in predicting adverse outcomes in patients with non-obstructive coronary heart disease (CAD).@*METHODS@#Clinical data of patients with non-obstructive CAD who underwent CCTA at the Affiliated Hospital of Jiangnan University from March 2014 to March 2018 were retrospectively analyzed and followed up, and the occurrence of major adverse cardiovascular event (MACE) was recorded. The patients were divided into MACE and non-MACE groups according to the occurrence of MACE. The clinical data, CCTA plaque characteristics including plaque length, stenosis degree, minimum lumen area, total plaque volume, non-calcified plaque volume, calcified plaque volume, plaque burden (PB) and remodelling index (RI), and CT-FFR were compared between the two groups. Multivaritate Cox proportional risk model was used to evaluate the relationship between clinical factors, CCTA parameters and MACE. The receiver operator characteristic curve (ROC curve) was used to assess the predictive power of outcome prediction model based on different CCTA parameters.@*RESULTS@#Finally 217 patients were included, of which 43 (19.8%) had MACE and 174 (80.2%) did not. The median follow-up interval was 24 (16, 30) months. The CCTA showed that patients in the MACE group had more severe stenosis than that in the non-MACE group [(44.3±3.8)% vs. (39.5±2.5)%], larger total plaque volume and non-calcified plaque volume [total plaque volume (mm3): 275.1 (197.1, 376.9), non-calcified plaque volume (mm3): 161.5 (114.5, 307.8) vs. 117.9 (77.7, 185.5)], PB and RI were larger [PB: 50.2% (42.1%, 54.8%) vs. 45.1% (38.2%, 51.7%), RI: 1.19 (0.93, 1.29) vs. 1.03 (0.90, 1.22)], CT-FFR value was lower [0.85 (0.80, 0.88) vs. 0.92 (0.87, 0.97)], and the differences were statistically significant (all P < 0.05). Cox regression analysis showed that non-calcified plaques volume [hazard ratio (HR) = 1.005. 95% confidence interval (95%CI) was 1.025-4.866], PB ≥ 50% (HR = 3.146, 95%CI was 1.443-6.906), RI ≥ 1.10 (HR = 2.223, 95%CI was 1.002-1.009) and CT-FFR ≤ 0.87 (HR = 2.615, 95%CI was 1.016-6.732) were independent predictors of MACE (all P < 0.05). The model based on CCTA stenosis degree+CT-FFR+quantitative plaque characteristics (including non-calcified plaque volume, RI, PB) [area under the ROC curve (AUC) = 0.91, 95%CI was 0.87-0.95] had significantly better predictive efficacy for adverse outcomes than the model based on CCTA stenosis degree (AUC = 0.63, 95%CI was 0.54-0.71) and the model based on CCTA stenosis degree+CT-FFR (AUC = 0.71, 95%CI was 0.63-0.79; both P < 0.01).@*CONCLUSIONS@#CT-FFR and plaque quantitative analysis based on CCTA are helpful in predicting adverse outcomes in patients with non-obstructive CAD. Non-calcified plaque volume, RI, PB and CT-FFR are important predictors of MACE. Compared with the prediction model based on stenosis degree and CT-FFR, the combined plaque quantitative index can significantly improve the prediction efficiency of adverse outcomes in patients with non-obstructive CAD.

ABSTRACT

Introducción: las infecciones estreptocócicas pueden presentarse con fiebre, inflamación faringoamigdalina con o sin exudados, petequias en el paladar, adenitis cervical, exantema escarlatiniforme y / o dolor abdominal. Resulta útil en área de urgencia disponer de pruebas de detección rápida de antígenos de S. pyogenes (DRASP) de alta especificidad y sensibilidad algo menor. Objetivos: conocer la utilidad de un test de DRASP en 2 servicios de Urgencia Pediátrica, describiendo las características clínicas y epidemiológicas de los pacientes estudiados durante el período de la investigación y su correlación con el cultivo de exudado faríngeo mediante el cálculo de sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y valor predictivo negativo (VPN). Material y métodos: estudio prospectivo, observacional, transversal en dos servicios de emergencia pediátrica. Se incluyeron niños a los que se les realizó DRASP y exudado faríngeo (EF) entre el 14 de febrero y el 13 de abril de 2018. Se registró: sexo, edad, motivo de consulta, diagnóstico, tratamiento, destino, resultado del test y de cultivo faríngeo. Se calcularon S, E, VPP y VPN. Resultados: n=241 niños. Rango 8 meses - 14 años, media 6 años. Consultaron por fiebre 103 niños (42,7%); por odinofagia 48, por erupción 11 y 47 por otros síntomas. Al 95% de los niños se le otorgó el alta. DRASP negativos 87,6% (N: 211) y positivos 12,9% (N: 31). EF negativos 80,1% (n: 193) y positivos para SßHGA en 13,7% (n: 33). La sensibilidad de la prueba fue del 52% y su especificidad del 93%. El VPP 55% y el negativo 92%. El diagnóstico más frecuente fue faringitis viral 132 (54,7%). Conclusiones: el test se aplicó fundamentalmente a escolares febriles, algunos con odinofagia. Contribuye a diferenciar en forma rápida la etiología y habilita a no usar antibióticos en caso de resultado negativo. Estos resultados avalan el uso de DRASP en la urgencia pediátrica.


Introduction: streptococcal infections can show fever, pharyngotonsillar inflammation with or without swabs, palatal petechiae, cervical adenitis, scarlatiniform rash and/or abdominal pain. Rapid detection tests for S. pyogenes antigens (DRASP) with high specificity and somewhat lower sensitivity are a useful at the Emergency Ward. Objectives: know the usefulness of a DRASP test in 2 Pediatric Emergency, describe the clinical and epidemiological characteristics of the patients studied during the research period and its correlation with the culture of pharyngeal exudates by calculating sensitivity (S) , specificity (S), positive predictive value (PPV), and negative predictive value (NPV). Material and Methods: prospective, observational, cross-sectional study carried out in two pediatric emergency wards. We included children who underwent DRASP and pharyngeal swab (PS) between February 14 and April 13, 2018. The following data were recorded: sex, age, reason for consultation, diagnosis, treatment, destination, test results and throat cultures. S, S, PPV and NPV were calculated. Results: n=241 children. Range 8 months - 14 years, average 6 years. 103 children (42.7%) consulted due to fever; 48 due to sore throat, 11 due to rash and 47 due to other symptoms. 95% of children were discharged. DRASP negative 87.6% (N: 211) and positive 12.9% (N: 31). Negative EP 80.1% (n: 193) and positive for SßHGA in 13.7% (n: 33). The test sensitivity was 52% and specificity 93%. The PPV 55% and the negative 92%. The most frequent diagnosis was viral pharyngitis 132 (54.7%). Conclusions: the test was applied mainly to febrile schoolchildren, some with odynophagia. A quick etiology differentiation is helpful, since it prevents antibiotics from being used in the event of a negative result. These results support the use of DRASP in pediatric emergency wards.

ABSTRACT

El Estimador de Sensibilidad a la Insulina de Punto Único (SPISE) es un biomarcador de sensibilidad a la insulina comparable al Índice de Matsuda. Se estima utilizando el IMC y los niveles de triglicéridos y HDL. El objetivo de este estudio fue comparar el rendimiento diagnóstico de SPISE con el de otros marcadores antropométricos de uso rutinario, como el IMC y la relación cintura | talla, en la pesquisa de insulinoresistencia (IR) y Síndrome Metabólico (MetS) en una muestra de 901 adolescentes de 11 a 16 años. En todos ellos se midió peso, talla, cintura, presión arterial, perfil lipídico, insulina y glicemia. La IR se diagnosticó con el HOMA-IR y el MetS con el criterio de Cook. Un zIMC ≥2.0 DE, un índice cintura/ talla ≥0.54 y un SPISE ≤ 5.4 fueron los puntos de corte utilizados para evaluar el rendimiento de estos marcadores en el diagnóstico de IR y MetS. No hubo diferencias por sexo en la prevalencia de obesidad, IR y MetS. Tanto en hombre como en mujeres, SPISE mostro una mejor capacidad para predecir el MetS (AUC: 0.95 y 0.89, respectivamente) e IR (AUC: 0.83 y 0.79, respectivamente) comparado con el rendimiento diagnóstico de la relación cintura | talla y el IMC-z. De igual manera, el SPISE mostro una mayor sensibilidad para identificar a los portadores de MetS e IR (96% y 75% en varones y 81% y 67% en mujeres, respectivamente). SPISE mostró una mejor capacidad para identificar el riesgo cardiometabólico asociado a la malnutrición por exceso al compararlo con otros indicadores de uso frecuente en clínica. Un índice de SPISE ≤5.4 fue un mejor predictor de MetS e IR que un IMC ≥2.0 DE y una relación cintura | talla ≥0.54.


The Single Point Insulin Sensitivity Estimator (SPISE) is a biomarker of insulin sensitivity comparable to the Matsuda Index. It is estimated using data on BMI, TG, and HDL. We aim to compare the diagnostic performance of SPISE with other routinely used anthropometric markers, such as BMI and waist-to-height ratio, in diagnosing insulin resistance (IR) and Metabolic Syndrome (MetS) in adolescents from 11 to 16 years. Weight, height, waist, blood pressure, lipid profile, insulin, and glycemia were measured. IR was diagnosed with the HOMA-IR and the MetS with the Cook criteria. A BMIz ≥2.0 SD, a waist-to-height ratio ≥0.54, and a SPISE ≤ 5.4 were the cut-off points used for diagnosing IR and MetS. There were no sex differences in the prevalence of obesity, IR, and MetS. In both males and females, SPISE showed a better ability to predict MetS (AUC: 0.95 and 0.89, respectively) and IR (AUC: 0.83 and 0.79, respectively) compared to the waist-to-height ratio and BMI-z. Similarly, SPISE showed greater sensitivity to identify adolescents with MetS and IR (96% and 75% in men and 81% and 67% in women, respectively) than the waist-to-height ratio and BMI-z. SPISE performed better in identifying obesity-related cardiometabolic risk than other frequently used clinical indicators. A SPISE index ≤5.4 was a better predictor of MetS and RI than a BMI ≥2.0 SD and a waist-to-height ratio ≥0.54.

ABSTRACT

Introducción. La obstrucción intestinal por bridas representa una causa común de consulta a los servicios de urgencias, pero hay poca claridad sobre qué pacientes tienen mayor riesgo de desarrollar complicaciones. El objetivo de este estudio fue diseñar y validar una escala de predicción de riesgo de desenlaces adversos en pacientes con obstrucción intestinal por bridas. Métodos. Estudio de cohorte retrospectivo realizado a partir de la base de datos MIMIC-IV. Se incluyeron pacientes adultos admitidos al servicio de urgencias entre 2008 y 2019, con diagnóstico de obstrucción intestinal por bridas. El desenlace principal fue el compuesto de resección intestinal, ingreso a unidad de cuidados intensivos y mortalidad por cualquier causa. Se diseñó una escala de predicción de riesgo asignando un puntaje a cada variable. Resultados. Se incluyeron 513 pacientes, 63,7 % hombres. El desenlace compuesto se presentó en el 25,7 % de los casos. La edad, historia de insuficiencia cardiaca y enfermedad arterial periférica, nivel de hemoglobina, recuento de leucocitos e INR constituyeron el mejor modelo de predicción de estos desenlaces (AUC 0,75). A partir de este modelo, se creó la escala simplificada HALVIC, clasificando el riesgo del desenlace compuesto en bajo (0-2 puntos), medio (3-4 puntos) y alto (5-7 puntos). Conclusión. La escala HALVIC es una herramienta de predicción simple y fácilmente aplicable. Puede identificar de manera precisa los pacientes con obstrucción intestinal por bridas con alto riesgo de complicaciones, permitiendo el ajuste individualizado de las estrategias de manejo para mejorar los desenlaces


Introduction. Adhesive Small Bowel Obstruction (ASBO) represents a common cause of consultation to the emergency department. Currently there is little clarity about which patients with ASBO are at increased risk of developing complications, potentially benefiting from early surgical management. The present study aims to design and validate a risk prediction scale for adverse outcomes in patients with ASBO. Methods. Retrospective cohort study performed from the MIMIC-IV database between 2008 and 2019. Adult patients admitted to the emergency department with a diagnosis of ASBO were included. The primary outcome was the composite of bowel resection, intensive care unit admission, and all-cause mortality. A risk prediction scale was designed by assigning a score to each variable according to the measure of association obtained in the logistic regression model. All analyses were performed in R statistical software (version 3.5.3). Results. Five-hundred-thirteen patients were included (men 63.7%, median age: 61 years). Composite outcome was present in 25.7% of cases. Age, history of heart failure and peripheral arterial disease, hemoglobin level, leukocyte count, and INR were the best predictors of these outcomes (AUC 0.75). Based on this model, the simplified HALVIC scale was created, classifying the risk of the composite outcome as low (0-2 points), medium (3-4 points) and high (5-7 points). Conclussion. The HALVIC scale is presented as a simple and easily applicable predictive tool in the clinical setting, which can accurately identify patients with ASBO at high risk of complications, allowing the surgeon to adjust management strategies individually and potentially improving the outcomes of these patients
