RESUMO

Non-Hodkin's lymphoma (NHL) is the most frequent hematologic malignancy in humans and dogs. NKG2D is one of the most critical receptors on NK cells, recognizing their natural ligands on malignant cells such as A and B major histocompatibility complex-related proteins (MIC-A and MIC-B). Soluble molecules (sMIC-A and sMIC-B) can interfere with immune synapsis between NK cells and tumor cells, impeding NK cytotoxicity. The main objectives of this study were to analyze, in dogs with diffuse large B cell lymphoma, NK cell lymphoma, and reactive lymphadenopathies, the role of NK cells, their activating receptors NKG2D and NKp46, and their ligands MIC-A and MIC-B, as well as soluble molecules sMIC-A and sMIC-B. Thirty-six dogs with a possible diagnosis of NHL and eight healthy dogs were studied. NHL was diagnosed in 28 (78 %) dogs; in the other 8 (22 %), reactive lymphadenopathies were present. Most of the lymphomas corresponded to B cell NHL (82 %). The most predominant subtype was diffuse large B cell lymphoma (21, 71.5 %), followed by five cases (18 %) that were Non-B Non-T lymphomas (presumably NK cell lymphomas) and other B cell lymphomas (3, 10.5%). There were no cases of T cell NHL. MIC-A was positive in 7 of 27 (26 %) cases of NHL, and MIC-B in 20 of 27 (74 %) NHL. In non-malignant lymphadenopathies, three (37.5 %) dogs were positive for MIC-A, and five (62.5 %) expressed MIC-B. Dogs with lymphoma had higher numbers of NK cells than eight healthy dogs. In 15 dogs (12 cases with NHL and three cases with reactive adenopathies) and eight controls, there were no differences in the number of NK cells expressing NKP46 and NKG2D. NHL dogs had higher values of sMIC-A and sMIC-B. B-cell and NK cell lymphomas correspond to 86 % and 14 % of all canine lymphomas. MIC-A, MIC-B, and sMIC-A and sMIC-B were increased in canine lymphomas.

RESUMO

The objective of the present study was to compare the prevalence of edentulism in Mexican adults with and without a diagnosis of type 2 diabetes mellitus (T2DM) when they are seeking dental care. A cross-sectional study was conducted on 1921 medical records of Mexican adults 40 years of age and older who sought dental care at clinics of a public university in Mexico. The dependent variable was edentulism, clinically determined through an oral examination. The main independent variable was the self-report of previous T2DM diagnosis made by a physician. Sociodemographic, socioeconomic and behavioral covariates were included in a multivariate binary logistic regression model. Overall edentulism prevalence was 8.4% (95% CI = 7.1-9.6). The prevalence of T2DM was 14.3% (n = 274). The prevalence of edentulism among individuals with T2DM was 13.1%, but only 7.6% among individuals without T2DM. In the multivariate binary logistic regression model, a previous T2DM diagnosis increased the probability of being edentulous 1.61 times (95% CI = 1.03-2.50). For each year a person's age increased, the likelihood of being edentulous increased by 12% (95% CI = 10-14%). In summary, a higher prevalence of edentulism was present in Mexican adults with T2DM and in those of older age. This information may be used by dental care providers and health policymakers to improve approaches to preventive care, as well as to characterize and anticipate care needs more accurately for the adult and older adult populations.

RESUMO

BACKGROUND: Tibial plateau fractures are traumatic injuries with severities ranging from nondisplaced to complicated fractures. This study describes the epidemiological characteristics of patients with tibial plateau fractures treated in five trauma clinics. METHODS: This retrospective, cross-sectional study included 1165 patients with tibial plateau fractures treated between December 2015 and May 2017. Subjects were selected from the medical records of five institutions based on the inclusion and exclusion criteria. Age, sex, laterality, fracture type, trauma mechanism, vehicle type, classification, and associated injuries were assessed via univariate and bivariate analyses. RESULTS: In total, 23.3% of patients with tibial fractures treated during the study period had tibial plateau fractures. Of those affected, 73% were men and 50% were younger than 40 years. Furthermore, 95.7% of fractures were caused by traffic accidents, 82.6% of which involved motorcycles. Fractures were closed in 93.1% of cases, and 78% of subjects had associated injuries. The most common fractures, according to Schatzker classification, were type VI (23%) and V (19.1%) fractures. CONCLUSIONS: Tibial plateau fractures are frequent injuries in our setting and mostly occur in men in their 30 s and 40 s. These fractures are typically caused by motorcycle traffic accidents. LEVEL OF EVIDENCE: IV.

RESUMO

Introducción. Las funciones del Comité de Ética Clínica (CEC) son educativas, normativas, consultivas, mediadoras y reflexivas. Como cualquier servicio de salud, las consultas de casos a un CEC deben ser sujetas a revisión y mejora de la calidad. Los objetivos fueron evaluar la factibilidad, la efectividad y la satisfacción de las recomendaciones ético-asistenciales dadas por el CEC, y evaluar su impacto en el equipo tratante y en la familia. Población y métodos. Estudio descriptivo, retrospectivo, cualicuantitativo, de casos clínicos presentados en el Comité de Ética Clínica del hospital desde el 1 de enero de 2013 hasta el 31 de diciembre de 2017, según datos del libro de actas, historias clínicas, registros de la Oficina de Comunicación a Distancia y entrevistas semiestructuradas al equipo de salud. Resultados. Se analizaron 108 casos (106 pacientes), 73 casos con encuesta y registros, y 35 solamente con registros. Los motivos principales más frecuentes de consulta fueron los siguientes: adecuación del esfuerzo terapéutico (46/42,6 %), compromiso neurológico grave (15/13,9 %), calidad de vida del paciente (11/10,2 %), conflictos entre el paciente, la familia y el sistema de salud (7/6,5 %), y rechazo del tratamiento por la familia (6/5,6 %). Se hallaron niveles altos de satisfacción (> 95 %) y niveles moderados de factibilidad (> 74 %) y efectividad (> 85 %). Solo en 50/108 casos (46,3 %) quedó registro en la historia clínica de la consulta al CEC y el 44 % de los profesionales opinó que la consulta tuvo un impacto positivo en la familia y en el paciente. Conclusiones. Los resultados contribuyeron a descubrir oportunidades de mejora, especialmente en la documentación y en la comunicación en el proceso de consulta.

RESUMO

BACKGROUND: Chronic mandibular hypomobility is characterized by a long-standing limitation of the mouth opening related to multiple etiologies, including elongation of the coronoid apophysis. Unlike the most frequent pathologies that cause coronoid elongation, such as hyperplasia, osteoma (OM), and osteochondroma (OC), the accessory mandibular condyle (AMC) is a rare entity. Clinical Presentation: The AMC shows a configuration similar to a normal mandibular condyle with an articular surface covered by fibrocartilage that articulates with the temporal wall of the zygomatic bone, and histologically, does not show neoplastic growth. The patient was treated with a coronoidectomy, removing the coronoid apophysis as well as the AMC. CLINICAL RELEVANCE: This case report presents a case of an AMC to describe the clinical, imaging, surgical, and histological characteristics, establishing its differential diagnosis with hyperplasia, OM, and OC of the coronoid apophysis.

RESUMO

AIMS: Type 1 diabetes (T1D) is a growing chronic disease. Evidence of whether the healthcare setting affects management and glycemic control is scarce. We evaluate outcomes in patients with T1D in private and public healthcare settings in Mexico, registered in the National T1D Registry in Mexico (RENACED-DT1). METHODS: Biochemical parameters, diabetes education, and treatment were analyzed considering the data registered in the last visit. Development of chronic complications was determined during follow-up. RESULTS: We included 1,603 patients; 71.5% (n = 1,146) registered in the public system, and 28.5% (n = 457) in a private institution. Patients in the public setting had higher HbA1c (8.6%, IQR: 7.3%-10.5% vs 7.7%, IQR: 7.0%-8.8%; p < 0.001). Indicators of diabetes education, glucose monitoring, and use of insulin-pumps were lower in the public setting. Patients in the public setting were at higher risk of diabetic chronic kidney disease, retinopathy, and neuropathy. Diabetes knowledge was a mediator between type of healthcare setting and the likelihood of achieving glycemic control. CONCLUSIONS: Patients registered in public healthcare settings have an adverse metabolic profile and higher risk of complications. Social factors need to be addressed in order to implement multidisciplinary measures focused on diabetes education for patients with T1D in Mexico.
