Encuesta nacional sobre cambios en las políticas de comunicación, visitas y cuidados al final de la vida en las unidades de cuidados intensivos durante las diferentes olas de la pandemia de COVID-19 (estudio COVIFAUCI) / National survey on changes in visitation, communication and end-of-life care policies in intensive care units through the different COVID-19 pandemic's waves (COVIFAUCI study)

Introducción La pandemia derivada de la infección por SARS-CoV-2 propició cambios en los cuidados tanto a familiares como a pacientes de cuidados intensivos durante las diferentes olas de incidencia del virus. La línea de humanización seguida por la mayoría de los hospitales se vio gravemente afectada por las restricciones aplicadas. Como objetivo, planteamos conocer las modificaciones experimentadas durante las diferentes olas de la pandemia por SARS-CoV-2 en España respecto a la política de visitas a los pacientes en UCI, el acompañamiento al final de la vida, y el uso de las nuevas tecnologías de la comunicación entre familiares, pacientes y profesionales. Métodos Estudio descriptivo transversal multicéntrico mediante encuesta a las UCI españolas desde febrero a abril de 2022. Se realizaron métodos de análisis estadísticos a los resultados según lo apropiado. El estudio fue avalado por la Sociedad Española de Enfermería Intensiva y Unidades Coronarias. Resultados Respondieron un 29% de las unidades contactadas. Los minutos de visita diarios de los familiares se redujeron drásticamente de 135 (87,5-255) a 45 (25-60) en el 21,2% de las unidades que permitían su acceso, mejorando levemente con el paso de las olas. En el caso de duelo, la permisividad fue mayor, aumentando el uso de las nuevas tecnologías para la comunicación paciente-familia en el caso del 96,5% de las unidades. Conclusiones Las familias de los pacientes ingresados en UCI durante las diferentes olas de la pandemia por COVID-19 han experimentado restricciones en las visitas y cambio de la presencialidad por técnicas virtuales de comunicación. Los tiempos de acceso se redujeron a niveles mínimos durante la primera ola, recuperándose con el avance de la pandemia pero sin llegar nunca a los niveles iniciales... (AU)

Introduction The pandemic derived from the SARS-CoV-2 infection led to changes in care for both relatives and intensive care patients during the different waves of incidence of the virus. The line of humanization followed by the majority of the hospitals was seriously affected by the restrictions applied. As an objective, we propose to know the modifications suffered during the different waves of the SARS-CoV-2 pandemic in Spain regarding the policy of visits to patients in the ICU, monitoring at the end of life, and the use of new technologies of communication between family members, patients and professionals. Methods Multicenter cross-sectional descriptive study through a survey of Spanish ICUs from February to April 2022. Statistical analysis methods were performed on the results as appropriate. The study was endorsed by the Spanish Society of Intensive Nursing and Coronary Units. Results Twenty-nine percent of the units contacted responded. The daily visiting minutes of relatives dropped drastically from 135 (87.5-255) to 45 (25-60) in the 21.2% of units that allowed their access, improving slightly with the passing of the waves. In the case of bereavement, the permissiveness was greater, increasing the use of new technologies for patient-family communication in the case of 96.5% of the units. Conclusions The family of patients admitted to the ICU during the different waves of the COVID-19 pandemic have suffered restrictions on visits and a change from face-to-face to virtual communication techniques. Access times were reduced to minimum levels during the first wave, recovering with the advance of the pandemic but never reaching initial levels. Despite the implemented solutions and virtual communication, efforts should be directed towards improving the protocols for the humanization of healthcare that allow caring for families and patients whatever the healthcare context.

La configuración de los tornillos en la osteosíntesis de las fracturas del cuello femoral no influye en los resultados funcionales ni mecánicos / The configuration of the screws in the osteosynthesis of fractures of the femoral neck does not influence the functional or mechanical outcomes

Antecedentes y objetivo: La síntesis con tornillos canulados es uno de los métodos aceptados en las fracturas de cuello femoral, aunque su óptima disposición es un tema en continuo debate. El objetivo principal fue comparar los resultados del paciente con fractura de cuello de fémur fijada con tres tornillos en configuración triangular y en triángulo invertido en el plano frontal. Materiales y métodos: Estudio retrospectivo y comparativo de 53 pacientes con fractura de cuello femoral intervenidos entre 2015 y 2022 mediante fijación con tres tornillos canulados: 22 conformados en triángulo (grupo triángulo) y 31 en triángulo invertido (grupo triángulo invertido). Se evaluó la funcionalidad mediante la escala modificada de Merlé d’Aubigné, la capacidad para la deambulación con la escala de Koval, así como las complicaciones postoperatorias. Resultados: En la escala de Merlé d’Aubigné la puntuación media fue de 16,7 en el grupo triángulo y de 16,1 en el grupo triángulo invertido (p=0,259). En la escala de Koval se observó una disminución significativa, pasando de 1,6 de media preoperatoria a 2,2 tras la cirugía (p=0,000), no hallando diferencias entre grupos. Hubo seis complicaciones postoperatorias en el grupo triángulo y tres en el grupo triángulo invertido (p=0,140). Conclusión: La configuración de los tornillos en el cuello femoral, tanto en forma de triángulo como en triángulo invertido, no influyó en los resultados funcionales ni mecánicos de los pacientes con fractura de cuello de fémur fijada mediante tres tornillos canulados.(AU)

Background and objective: Synthesis with cannulated screws is one of the accepted methods in femoral neck fractures, although its optimal configuration is a subject in continuous debate. The main objective was to compare the results of the patient with a femoral neck fracture fixed with three screws in triangle and inverted triangle configuration in the frontal plane. Materials and methods: Retrospective and comparative study of 53 patients with femoral neck fracture, operated between 2015 and 2022 with fixation with three cannulated screws, 22 with a triangle configuration (triangle group) and 31 in an inverted triangle (inverted triangle group). Functionality was evaluated using the modified Merlé d’Aubigné scale, walking ability using the Koval scale, as well as postoperative complications. Results: On the Merlé d’Aubigné scale, the mean score was 16.7 in the triangle group and 16.1 in the inverted triangle group (P=.259). On the Koval scale, a significant decrease was observed, going from 1.6 preoperative mean to 2.2 after surgery (P=.000), finding no differences between groups. There were six postoperative complications in the triangle group and three in the inverted triangle group (P=.140). Conclusion: The configuration of the screws in the femoral neck, both in the form of a triangle and an inverted triangle, did not influence the functional or mechanical outcomes of the patients with a femoral neck fracture fixed with three cannulated screws.(AU)

Incidence of childhood cancer in Latin America and the Caribbean: coverage, patterns, and time trends / Incidencia del cáncer infantil en América Latina y el Caribe: cobertura de los registros, patrones y tendencias a lo largo del tiempo / Incidência de câncer infantil na América Latina e no Caribe: cobertura, padrões e tendências temporais

ABSTRACT Objective. To provide a comprehensive overview of geographical patterns (2001-2010) and time trends (1993-2012) of cancer incidence in children aged 0-19 years in Latin America and the Caribbean (LAC) and interpret the findings in the context of global patterns. Methods. Geographical variations in 2001-2010 and incidence trends over 1993-2012 in the population of LAC younger than 20 years were described using the database of the third volume of the International Incidence of Childhood Cancer study containing comparable data. Age-specific incidence per million person-years (ASR) was calculated for population subgroups and age-standardized (WSR) using the world standard population. Results. Overall, 36 744 unique cases were included in this study. In 2001-2010 the overall WSR in age 0-14 years was 132.6. The most frequent were leukemia (WSR 48.7), central nervous system neoplasms (WSR 23.0), and lymphoma (WSR 16.6). The overall ASR in age group 15-19 years was 152.3 with lymphoma ranking first (ASR 30.2). Incidence was higher in males than in females, and higher in South America than in Central America and the Caribbean. Compared with global data LAC incidence was lower overall, except for leukemia and lymphoma at age 0-14 years and the other and unspecified tumors at any age. Overall incidence at age 0-19 years increased by 1.0% per year (95% CI [0.6, 1.3]) over 1993-2012. The included registries covered 16% of population aged 0-14 years and 10% of population aged 15-19 years. Conclusions. The observed patterns provide a baseline to assess the status and evolution of childhood cancer occurrence in the region. Extended and sustained support of cancer registration is required to improve representativeness and timeliness of data for childhood cancer control in LAC.

RESUMO Objetivo. Apresentar uma visão abrangente dos padrões geográficos (2001 a 2010) e das tendências temporais (1993 a 2012) da incidência de câncer em crianças e jovens de 0 a 19 anos na América Latina e no Caribe (ALC) e interpretar os resultados no contexto de padrões mundiais. Métodos. Foram descritas variações geográficas de 2001 a 2010 e tendências de incidência de 1993 a 2012 na população com menos de 20 anos da ALC usando informações comparáveis da base de dados do terceiro volume do estudo International Incidence of Childhood Cancer. Foram calculadas taxas de incidência específica por idade por milhão de pessoas-ano (ASR, na sigla em inglês) para subgrupos populacionais e taxas padronizadas por idade usando a população padrão mundial (WSR, na sigla em inglês). Resultados. No total, foram incluídos 36 744 casos únicos. No período de 2001 a 2010, a WSR para todos os tumores combinados na faixa etária de 0 a 14 anos foi de 132,6. Os diagnósticos mais frequentes foram leucemia (WSR de 48,7), neoplasias do sistema nervoso central (WSR de 23,0) e linfoma (WSR de 16,6). A ASR para todos os tumores combinados na faixa etária de 15 a 19 anos foi de 152,3, e a maior taxa foi a de linfoma (ASR de 30,2). A incidência foi maior no sexo masculino do que no sexo feminino e maior na América do Sul do que na América Central e no Caribe. De modo geral, em comparação com as estimativas mundiais, a incidência na ALC foi menor, exceto para leucemia e linfoma entre 0 e 14 anos e para outros tumores e tumores não especificados em qualquer idade. A taxa de incidência na faixa etária de 0 a 19 anos aumentou em 1,0% ao ano (IC de 95% [0,6, 1,3]) entre 1993 e 2012. Os registros incluídos cobriam 16% da população de 0 a 14 anos e 10% da população de 15 a 19 anos. Conclusões. Os padrões observados servem de referência para avaliar o status e a evolução da ocorrência de câncer infantil na região. É necessário garantir um apoio ampliado e consistente aos registros de câncer para aprimorar a representatividade e a disponibilidade das informações em tempo adequado para o controle do câncer infantil na ALC.

[Anterior shoulder instability with Hill-Sachs on-track. Bankart or Bankart-remplissage?] / Inestabilidad anterior de hombro con lesión de Hill-Sachs on-track. ¿Bankart o Bankart-remplissage?

INTRODUCTION: in patients with anterior glenohumeral (GH) instability together with an off-track or engaging Hill-Sachs (HS) defect, Bankart-remplissage (B-R) surgery reduces the recurrence rate when compared to Bankart (B) surgery alone. There is controversy regarding whether the recurrence rate also decreases in patients with on-track or non-engaging Hill-Sachs defects. OBJECTIVE: to compare the recurrence rate and clinical evolution of patients with anterior glenohumeral instability with 'on-track' Hill-Sachs defect treated with either B or B-R surgery. MATERIAL AND METHODS: non-randomized, retrospective, single-center cohort study of patients with anterior glenohumeral instability and on-track Hill-Sachs defect, operated between January 2010 and December 2018. Patients operated with B versus B-R were compared. Recurrence, complications and re-operation were recorded. In addition, VAS, SSV, WOSI and qDASH scores were obtained and compared in both groups. RESULTS: of the 105 patients who met the inclusion criteria, 78 (74.3%) patients had a complete follow-up (52 B and 26 B-R, 4.3 years median follow-up). There was a higher recurrence rate in group B compared to B-R, with this difference not reaching statistical significance (17.3% vs 7.7%, p = 0.21). There were no significant differences in residual pain, feeling of instability, complications or VAS, qDASH, SSV or WOSI scores between both groups. In the subgroup analysis, patients who practiced contact sports and were operated with B showed higher recurrence rates (24.1% vs 0%, p = 0.08) and complications (41.4% vs 18.2%, p = 0.16) when compared to B + R, although these differences were not significant. CONCLUSION: there were no significant differences in recurrence rates and functional evolution between patients with anterior glenohumeral instability operated with B or B-R surgery. Comparative, prospective studies should be performed to establish definitive recommendations.

INTRODUCCIÓN: en pacientes con inestabilidad glenohumeral (GH) anterior con defecto de Hill-Sachs (HS) off-track o enganchante, Bankart-remplissage (B + R) reduce tasa de recurrencia en comparación a Bankart aislado (B). Hay controversia si tasa de recurrencia también disminuye en pacientes con defecto de HS on-track o no enganchantes. OBJETIVO: comparar la tasa de recurrencia y evolución clínica entre la cirugía de B versus B-R en pacientes operados por inestabilidad glenohumeral anterior con defecto de Hill-Sachs on-track. MATERIAL Y MÉTODOS: estudio de cohorte, no randomizado, retrospectivo y unicéntrico, en pacientes operados por inestabilidad glenohumeral anterior, entre Enero 2010 y Diciembre de 2018. Se incluyen sólo pacientes con defecto de Hill-Sachs on-track. Fueron comparados pacientes operados con cirugía de B versus B + R. Se consigna recurrencia, complicación, reoperación y sensación de inestabilidad. Además, se realizan y comparan puntajes de EVA, SSV, WOSI y qDASH. RESULTADOS: de los 105 pacientes que cumplieron criterios de inclusión, 78 (74.3%) realizaron seguimiento completo (52 B y 26 B + R, 4.3 años mediana de seguimiento). Hubo mayor tasa de recurrencia en grupo B en comparación a B + R, siendo esta diferencia no significativa (17.3% versus 7.7%, p = 0.21). No hubo diferencia significativa en dolor residual, sensación de inestabilidad residual, complicaciones o puntajes de escala EVA, qDASH, SSV ni WOSI. En análisis por subgrupo, pacientes con deportes de contacto, B tienen mayor tasa de recurrencia (24.1% versus 0%, p = 0.08) y complicaciones comparadas con B + R (41.4% versus 18.2%, p = 0.16), siendo estas diferencias no significativas. CONCLUSIÓN: no hubo diferencias significativas en tasa de recurrencia y evolución funcional entre cirugía de Bankart aislado o Bankart-remplissage para inestabilidad glenohumeral anterior asociada a defecto de Hill-Sachs on-track. Estudios comparativos, prospectivos deben realizarse para establecer recomendaciones definitivas.

Alteration of functional connectivity in the cortex and major brain networks of non-human primates following focused ultrasound exposure.

Focused ultrasound (FUS) is a non-invasive neuromodulation technology that is being investigated for potential treatment of neurological and psychiatric disorders. Focused ultrasound combined with microbubbles can temporarily open the intact blood-brain barrier (BBB) of animals and humans, and facilitate drug delivery. FUS exposure, either with or without microbubbles, has been demonstrated to alter the behavior of non-human primates, and previous work has demonstrated transient and long-term effects of FUS neuromodulation on functional connectivity using resting state functional MRI. However, it is unknown whether opening the BBB affects functional connectivity differently than FUS alone. Thus we applied FUS alone (neuromodulation) and FUS with microbubbles (BBB opening) in the dorsal striatum of lightly anesthetized non-human primates, and compared changes in functional connectivity in major brain networks. We found different alteration patterns between FUS neuromodulation and FUS-mediated BBB opening in several cortical areas, and we also found that applying FUS to a deep brain structure can alter functional connectivity in the default mode network and frontotemporal network.

Long-term oncological outcomes of endoscopic full-thickness resection after previous incomplete resection of low-risk T1 CRC (LOCAL-study): study protocol of a national prospective cohort study.

BACKGROUND: T1 colorectal cancer (CRC) without histological high-risk factors for lymph node metastasis (LNM) can potentially be cured by endoscopic resection, which is associated with significantly lower morbidity, mortality and costs compared to radical surgery. An important prerequisite for endoscopic resection as definite treatment is the histological confirmation of tumour-free resection margins. Incomplete resection with involved (R1) or indeterminate (Rx) margins is considered a strong risk factor for residual disease and local recurrence. Therefore, international guidelines recommend additional surgery in case of R1/Rx resection, even in absence of high-risk factors for LNM. Endoscopic full-thickness resection (eFTR) is a relatively new technique that allows transmural resection of colorectal lesions. Local scar excision after prior R1/Rx resection of low-risk T1 CRC could offer an attractive minimal invasive strategy to achieve confirmation about radicality of the previous resection or a second attempt for radical resection of residual luminal cancer. However, oncologic safety has not been established and long-term data are lacking. Besides, surveillance varies widely and requires standardization. METHODS/DESIGN: In this nationwide, multicenter, prospective cohort study we aim to assess feasibility and oncological safety of completion eFTR following incomplete resection of low-risk T1 CRC. The primary endpoint is to assess the 2 and 5 year luminal local tumor recurrence rate. Secondary study endpoints are to assess feasibility, percentage of curative eFTR-resections, presence of scar tissue and/or complete scar excision at histopathology, safety of eFTR compared to surgery, 2 and 5 year nodal and/or distant tumor recurrence rate and 5-year disease-specific and overall-survival rate. DISCUSSION: Since the implementation of CRC screening programs, the diagnostic rate of T1 CRC is steadily increasing. A significant proportion is not recognized as cancer before endoscopic resection and is therefore resected through conventional techniques primarily reserved for benign polyps. As such, precise histological assessment is often hampered due to cauterization and fragmentation and frequently leads to treatment dilemmas. This first prospective trial will potentially demonstrate the effectiveness and oncological safety of completion eFTR for patients who have undergone a previous incomplete T1 CRC resection. Hereby, substantial surgical overtreatment may be avoided, leading to treatment optimization and organ preservation.

Confiabilidad interevaluador de la medición de la excursión diafragmática y fracción de engrosamiento diafragmático mediante ultrasonografía en voluntarios sanos / Inter-rater reliability of the measurement of diaphragmatic excursion and fraction of diaphragmatic thickening by ultrasonography in healthy volunteers

Antecedentes y objetivo: Determinar la confiabilidad interevaluador en la medición ultrasonográfica (US) de la excursión diafragmática (ED) y la fracción de engrosamiento diafragmático (FED) realizada por profesionales de salud no médicos en voluntarios sanos. Participantes y métodos: Estudio observacional prospectivo en un hospital de tercer nivel en Cali, Colombia. Se realizaron mediciones a 30 voluntarios sanos escogidos mediante muestreo a conveniencia, sin antecedentes de enfermedades pulmonares, con edades entre los 18-60 años. Previamente se realizó una prueba piloto con 8 voluntarios sanos. Las mediciones US de ED y FED se basaron en protocolos publicados anteriormente. Cada evaluador observaba independientemente varios ciclos de respiración tranquila normal durante 3minutos para establecer una línea de base. Para evaluar la confiabilidad interevaluador en las mediciones de ED y FED se utilizó el índice de correlación intraclase (ICC), con intervalos de confianza del 95% y un p<0,05. Resultados: Se identificó concordancia sustancial en la medición de la ED en las ventanas esplénica y hepática debido a que el ICC fue mayor a 0,6 (p<0,05). La medición de la FED en la ventana hepática mostró concordancia leve tanto en el modo 2D como en el modo M (p>0,05). En la ventana esplénica la medición de la FED en el modo 2D se identificó concordancia regular y para el modo M se encontró una concordancia leve (p>0,05). Conclusiones: La US diafragmática constituye un método reproducible con aceptable confiabilidad interevaluador para la medición del grosor inspiratorio/espiratorio y con confiabilidad pobre para la medición de FED.(AU)

Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3minutes to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a P<.05. Results: Substantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (P<.05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (P>.05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (P>.05).Conclusions: The diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.(AU)

Correlation between biological responses in vitro and in vivo to Ca-doped sol-gel coatings assessed using proteomic analysis.

Poor correlation between the results of in vitro testing and the subsequent in vivo experiments hinders the design of biomaterials. Thus, new characterisation methods are needed. This study used proteomic and histological techniques to analyse the effects of Ca-doped biomaterials in vitro and in vivo and verify the correlation between the two systems. The sol-gel route was employed to synthesise coatings functionalised with 0.5 and 5 wt% of CaCl2. Morphology of the coatings was examined using SEM; the Ca2+ ion release from the materials was analysed by means of ICP-AES spectroscopy. The osteogenic and inflammatory responses were inspected in vitro in human osteoblasts (HOb) and TPH-1 monocytes. The in vivo experiments used a rabbit model. The nLC-MS/MS-based proteomic methods were utilised to analyse the proteins adhering to the material samples incubated with human serum or examine protein expression in the tissues close to the implants. Ca-doped biomaterials caused a remarkable increase in the adsorption of coagulation-related proteins, both in vitro (PLMN, THRB, FIBA and VTNC) and in vivo (FBLN1, G1U978). Enhanced affinity to these materials was also observed for proteins involved in inflammation (CO5, C4BPA, IGHM and KV302 in vitro; CARD6, DDOST and CD14 in vivo) and osteogenic functions (TETN, PEDF in vitro; FBN1, AHSG, MYOC in vivo). The results obtained using different techniques were well matched, with a good correlation between the in vitro and in vivo experiments. Thus, the proteomic analysis of biological responses to biomaterials in vitro is a useful tool for predicting their impact in vivo.

Percutaneous cryoablation: a novel treatment option in non-visceral metastases of the abdominal cavity after prior surgery.

PURPOSE: To assess the primary safety and oncological outcome of percutaneous cryoablation in patients with non-visceral metastases of the abdominal cavity after prior surgery. METHODS: All patients with non-visceral metastases after prior abdominal surgery, treated with percutaneous cryoablation, and at least one year of follow-up were retrospectively identified. Technical success was achieved if the ice-ball had a minimum margin of 10 mm in three dimensions on the per-procedural CT images. Complications were recorded using the Society of Interventional Radiology (SIR) classification system. Time until disease progression was monitored with follow-up CT and/or MRI. Local control was defined as absence of recurrence at the site of ablation. RESULTS: Eleven patients underwent cryoablation for 14 non-visceral metastases (mean diameter 20 ± 9 mm). Primary tumor origin was renal cell (n = 4), colorectal (n = 3), granulosa cell (n = 2), endometrium (n = 1) and appendix (n = 1) carcinoma. Treated metastases were localized retroperitoneal (n = 8), intraperitoneal (n = 2), or in the abdominal wall (n = 4). Technical success was achieved in all procedures. After a median follow-up of 27 months (12-38 months), all patients were alive. Local control was observed in 10/14 non-visceral metastases, and the earliest local progression was detected after ten months. No major adverse events occurred. One patient suffered a minor asymptomatic adverse event. CONCLUSION: This proof-of-concept study suggests that cryoablation can be a minimal invasive treatment option in a selected group of patients with non-visceral metastases in the abdominal cavity after prior surgery.

[Correlation between clinical and tomographic variables in patients with neurocysticercosis. A study in a cohort of patients in Sierra Norte, Ecuador, between 2019 and 2020]. / Correlación entre variables clínicas y tomográficas en pacientes con neurocisticercosis. Estudio en una cohorte de pacientes de la Sierra Norte ecuatoriana entre 2019 y 2020.

INTRODUCTION: Neurocysticercosis (NCC) is the most frequent parasitic disease in the central nervous system of humans. OBJECTIVE: to establish the correlation between clinical and tomographic variables in patients with neurocysticercosis in the neurology consultation of Hospital San Vicente de Paul and Hospital IESS Ibarra, during the year 2020. PATIENTS AND METHODS: descriptive, correlational and cross-sectional research. POPULATION AND SAMPLE: 93 patients. The information was collected in the neurology consultation. Clinical and imaging criteria were used for diagnosis. Odds Ratio (OR; 95% CI) was calculated. For multivariate analysis, binary logistic regression models were used. Statistical significance was considered when the value of p <0.05. SYMPTOMS: headache (77.4%), epilepsy (41.9%). Tomographic findings: size < 1 cm (67.7%), single lesion (54.8%), supratentorial (93.5%). There were several clinical / tomographic correlations in the bivariate analysis, the presence of epilepsy was associated with lesions of size >1 cm (OR: 9.65; 95% CI: 3.48-26.7), the vesicular + ventricular colloidal stage + nodular (OR: 3.90; 95% CI: 1.64-9.28) and parenchymal topography (OR: 5.03; 95% CI: 2.03-12.4) (p < 0.05). In the multivariate analysis, epilepsy was not associated with tomographic aspects such as the size, stage and topography of the cysticerci (p < 0.05). Headache and reduced muscle strength were associated with parenchymal topography and stage of lesions respectively (p < 0.05). CONCLUSIONS: Despite having a wide clinical spectrum, the presence of epilepsy, headache, and reduced muscle strength seem to be the most representative manifestations, so their inclusion in the development of prognostic scores should be evaluated, which allow evaluating the approach diagnostic and evolutionary in subsequent research.

TITLE: Correlación entre variables clínicas y tomográficas en pacientes con neurocisticercosis. Estudio en una cohorte de pacientes de la Sierra Norte ecuatoriana entre 2019 y 2020.Introducción. La neurocisticercosis es la enfermedad parasitaria más frecuente en el sistema nervioso central de los humanos. Objetivo. Establecer la correlación entre variables clínicas y tomográficas en pacientes con neurocisticercosis en la consulta de neurología del Hospital San Vicente de Paúl y el Hospital Instituto Ecuatoriano de Seguridad Social de Ibarra durante 2020. Pacientes y métodos. Investigación descriptiva, correlacional y transversal. Población y muestra: 93 pacientes. La información se recolectó en la consulta de neurología. Para el diagnóstico se utilizaron criterios clínicos e imagenológicos. Se calculó la odds ratio (OR) ­intervalo de confianza al 95% (IC 95%)­. Para el análisis multivariado, se utilizaron modelos de regresión logística binaria. Se consideró significación estadística cuando p menor de 0,05. Resultados. Síntomas: cefalea (77,4%) y crisis epilépticas (41,9%). Hallazgos tomográficos: tamaño menor de 1 cm (67,7%), lesión única (54,8%) y lesión supratentorial (93,5%). Hubo varias correlaciones clinicotomográficas en el análisis bivariado: la presencia de crisis epilépticas se asoció con lesiones de tamaño > 1 cm (OR: 9,65; IC 95%: 3,48-26,7), el estadio vesicular + ventricular coloidal + nodular (OR: 3,9; IC 95%: 1,64-9,28) y la topografía parenquimatosa (OR: 5,03; IC 95%: 2,03-12,4) (p menor de 0,05). La cefalea y la reducción de la fuerza muscular se asociaron con topografía parenquimatosa y estadio de las lesiones, respectivamente (p menor de 0,05). Conclusiones. A pesar de cursar con un amplio espectro clínico, la presencia de crisis epilépticas, cefalea y reducción de la fuerza muscular parece ser la manifestación más representativa, por lo que debería evaluarse su inclusión en el desarrollo de puntuaciones pronósticas que permitan evaluar el enfoque diagnóstico y evolutivo por estudio de imagen en investigaciones posteriores.
