RESUMO
GacS/GacA is a widely distributed two-component system playing an essential role as a key global regulator, although its characterization in phytopathogenic bacteria has been deeply biased, being intensively studied in pathogens of herbaceous plants but barely investigated in pathogens of woody hosts. P. savastanoi pv. savastanoi (Psv) is characterized by inducing tumours in the stem and branches of olive trees. In this work, the model strain Psv NCPPB 3335 and a mutant derivative with a complete deletion of gene gacA were subjected to RNA-Seq analyses in a minimum medium and a medium mimicking in planta conditions, accompanied by RT-qPCR analyses of selected genes and phenotypic assays. These experiments indicated that GacA participates in the regulation of at least 2152 genes in strain NCPPB 3335, representing 37.9 % of the annotated CDSs. GacA also controls the expression of diverse rsm genes, and modulates diverse phenotypes, including motility and resistance to oxidative stresses. As occurs with other P. syringae pathovars of herbaceous plants, GacA regulates the expression of the type III secretion system and cognate effectors. In addition, GacA also regulates the expression of WHOP genes, specifically encoded in P. syringe strains isolated from woody hosts, and genes for the biosynthesis of phytohormones. A gacA mutant of NCPPB 3335 showed increased virulence, producing large immature tumours with high bacterial populations, but showed a significantly reduced competitiveness in planta. Our results further extend the role of the global regulator GacA in the virulence and fitness of a P. syringae pathogen of woody hosts.
RESUMO
BACKGROUND: This study evaluated the cost-effectiveness of an intervention based on a training course for community pharmacists and a smoking cessation service (CESAR©), using limited societal and the health provider perspectives. METHODS: Non-randomized controlled trial of 12-months' follow-up. Spanish community pharmacists who were previously trained with CESAR© formed the intervention group (n = 102), and control group delivered usual care (n = 80). CESAR Patients were smokers identified by the community pharmacists when they attended the pharmacy. Data were self-reported. Outcomes were smoking cessation and quality-of-life (EQ-5D-3L) and were collected at baseline, 6, and 12 months. Costs data included direct health costs, work loss, and intervention costs. Smoking cessation was analyzed through logistic regression models. Generalized linear models were carried out for quality-adjusted life year (QALY) and costs. Incremental cost-effectiveness ratio (ICER) and cost-utility ratio (ICUR) were calculated. RESULTS: In total, 800 smoking patients were included in the intervention group and 278 in the control group. Of these, 487 and 151 patients completed the study, respectively. Costs were lower in the intervention group compared to the control group in both perspectives. At 12 months, 54.3% and 37.1% patients from the intervention and the control groups reported smoking cessation, respectively. The difference in probability of cessation in the intervention compared to the control group was 17.6% (CI:0.05; 0.25). The mean QALY was higher in the intervention group [0.03(CI: 0.01; 0.07)]. The ICER and the ICUR were dominant for the intervention group. CONCLUSION: This intervention for smoking cessation showed that the CESAR© intervention, that combined a training for community pharmacists with a smoking cessation service was efficient for smoking cessation and QALY at 12 months' follow-up. TRIAL REGISTRATION: NCT05461066, retrospectively registered (July 15, 2022).

ABSTRACT OBJECTIVE To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008-2009 and 2017-2018. A total of 3,095 adolescents were evaluated in 2008-2009 and 3,015 in 2017-2018. Food consumption was assessed using two dietary records in 2008-2009 and two 24-hour recalls in 2017-2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008-2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group's eating habits. Among female adolescents, in 2008-2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and processed meats. CONCLUSION The dietary patterns identified in 2008-2009 and 2017-2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008-2009, was replaced by the traditional Brazilian.

Introduction. Frailty syndrome generates a high risk of adverse outcomes and mortality, and its prevalence is elevated in patients with end-stage kidney disease. Few studies have reported the prevalence and outcomes of frailty in populations from less developed countries. Objective. To identify the clinical outcomes and factors associated with the frailty syndrome in patients with stage five chronic kidney disease who started renal replacement therapy - both hemodialysis and peritoneal dialysis- in a dialysis center in Bucaramanga, Colombia. Materials and methods. This was a prospective study of patients with end-stage kidney disease who initiated dialysis at a center in Colombia and had a twelve-month follow-up. Results. The overall frailty prevalence was 50.47% and two out of three patients older than 65 years had the syndrome. We found significantly higher followup mortality among patients with frailty: odds ratio of 2.95 (CI: 1.07- 8.13; p=0.036) in unadjusted analysis. Conclusions. Literature shows that compared to developed nations, Latin American adults are facing a higher prevalence of chronic diseases, and frailty syndrome is increasing. In this study, according to the FRAIL scale, having a frailty syndrome predicts a higher mortality; hypoalbuminemia and low creatinine levels at the beginning of dialysis could act as predictors of its diagnosis.
Introducción. El síndrome de fragilidad implica un alto riesgo de desenlaces adversos y mortalidad, y tiene una prevalencia elevada en pacientes con enfermedad renal en etapa terminal. Hay pocos estudios que investiguen la prevalencia y los desenlaces de este síndrome de fragilidad en las poblaciones de los países en desarrollo. Objetivo. Identificar los desenlaces clínicos y los factores asociados al síndrome de fragilidad en los pacientes con enfermedad renal crónica en estadio cinco que inician terapia de reemplazo renal -con hemodiálisis o diálisis peritoneal- en un centro de diálisis de Bucaramanga, Colombia. Materiales y métodos. Se trató de un estudio prospectivo de pacientes con enfermedad renal en etapa terminal que iniciaron diálisis en un centro de Colombia y a quienes se les hizo seguimiento durante doce meses. Resultados. La prevalencia global del síndrome de fragilidad fue del 50,47 % y dos de cada tres pacientes mayores de 65 años lo presentaban. Se encontró una mortalidad significativamente mayor entre los pacientes con síndrome de fragilidad: razón de probabilidad de 2,95 (IC:1,07-8,13; p=0,036) en el análisis no ajustado. Conclusiones. La literatura muestra que, en comparación con los países desarrollados, los adultos latinoamericanos presentan una mayor prevalencia de enfermedades crónicas y un aumento progresivo del síndrome de fragilidad. En este estudio, la fragilidad -según la escala FRAIL- predijo una mayor mortalidad. Además, la hipoalbuminemia y los niveles bajos de creatinina al inicio de la diálisis podrían actuar como elementos predictores de su diagnóstico.
RESUMO
Dada la respiración nasal preferencial que tiene la población pediátrica en los primeros meses de vida, la obstrucción nasal tiene más repercusiones a nivel clínico a diferencia de un adulto, lo cual hace más prioritario su diagnóstico y manejo. Una de las principales causas de obstrucción nasal en niños son las masas nasales, las cuales debido a sus múltiples etiologías causan bastante incertidumbre diagnóstica en el equipo médico. En este artículo se presenta el caso de una paciente de 10 meses con una masa en el ala nasal de crecimiento rápido; se realiza un rápido diagnóstico de rabdomiosarcoma que requiere un adecuado manejo. El rabdomiosarcoma con patrón alveolar se presenta de forma inusual en esta ubicación, es por esto por lo que se considera importante presentar este caso para mantenerlo en el algoritmo diagnóstico como una posibilidad y que, así como en el caso presentado, se pueda tener un diagnóstico temprano, un tratamiento adecuado y un resultado estético y funcional favorable.
Given preferential nasal breathing in the first months of life in the pediatric population, nasal obstruction has more clinical repercussions than it would have in adults, hence the need to give higher priority to its diagnosis and management. One of the main causes of nasal obstruction in children is the presence of nasal masses, which cause considerable diagnostic uncertainty in the medical team, because of their multiple etiologies. In this article, the case of a 10-month-old patient with a rapidly growing mass in the nasal ala is presented. A rhabdomyosarcoma was promptly diagnosed and adequately managed. Rhabdomyosarcoma with an alveolar pattern occurs in an unusual way in this location; for this reason, this case is important in order to include this possibility in the diagnostic algorithm and, as was the case in this patient, reach an early diagnosis and institute adequate treatment resulting in favorable aesthetic and functional results.

RESUMEN Objetivo: La incertidumbre de una posible transmisión posnatal por SARS-CoV-2 genera un desafío entre aplicar o evitar los cuidados esenciales del recién nacido para prevenir la transmisión. La revisión sistemática tiene como objetivo describir el impacto de los cuidados esenciales del neonato en la transmisión posnatal del SARS-CoV-2. Métodos: Se realizó una revisión sistemática en bases de datos electrónicas, se incluyeron estudios observacionales, serie de casos y reporte de casos. Dos investigadores de forma independiente evaluaron los criterios de inclusión, la calidad metodológica y la extracción de datos. Resultados: Se tamizaron 208 estudios para una inclusión final de 9 artículos relevantes. El reporte de transmisión del virus SARS-CoV-2 está centrado en la posibilidad de transferencia por la leche materna y ausencia de información acerca de la transmisión por otros cuidados esenciales, sin embargo, se observa un bajo uso en la práctica clínica de los cuidados esenciales del recién nacido hijo de madre con COVID- 19. Conclusiones: La información es limitada sobre la posible transmisión del SARS-CoV-2 a través de los cuidados esenciales del recién nacido, sin embargo, la pandemia ha impactado de forma importante los mismos. Según los hallazgos en la literatura, es mayor el beneficio de estas intervenciones y las recomendaciones científicas promueven su aplicación empleando las medidas de protección personal para la madre y el personal de salud.
ABSTRACT Objective: The uncertainty of a possible postnatal transmission by SARS-CoV-2 creates a challenge between applying or avoiding essential newborn care to prevent transmission. The objective of the systematic review is to describe the impact of essential neonate care on the postnatal transmission of SARS-CoV-2. Methods: A systematic review was carried out in electronic databases, observational studies, case series, and case reports. Two investigators independently assessed the inclusion criteria, methodological quality, and data extraction. Results: 208 studies were screened for a final inclusion of 9 relevant articles. The transmission report of the SARS-CoV-2 virus is focused on the possibility of transfer through breast milk and the absence of information about transmission by other essential care, however, a low use, in clinical practice, of essential care for the newborn child of a mother with COVID-19, is observed. Conclusions: Information is limited on the possible transmission of SARS-CoV-2 through essential newborn care; however, the pandemic has had a significant impact on them. According to the findings in the literature, the benefit of these interventions is greater, and the scientific recommendations promote their application, using personal protection measures for the mother and the healthcare personnel.

Resumen Introducción: El síndrome postimplantación es un trastorno frecuente, producido en el posoperatorio inmediato posterior al tratamiento endovascular de la enfermedad aórtica, caracterizado por la presencia de anorexia, dolor lumbar, leucocitosis, fiebre y elevación de la proteína C reactiva, asociado ocasionalmente a disminución del recuento de plaquetas o alteración de la coagulación. Objetivos: Determinar la incidencia y morbilidad asociada al síndrome postimplantación, posterior a la reparación endovascular de la patología aórtica. Material y Métodos: Estudio observacional y descriptivo, donde se analiza la presencia del síndrome post implantación en pacientes sometidos a Reparación endovascular torácica aórtica (TEVAR) y Reparación endovascular de aneurisma (EVAR), durante un período de 10 años (2009 al 2019), en el Hospital Dr. Eduardo Pereira de Valparaíso, Chile. Resultados: Se incluyeron 112 reparaciones endovasculares, 72,32% correspondientes a EVAR y 27,68% a TEVAR, incidencia del síndrome post implantación (17,85%), factores de riesgo asociados: edad ≤ 75 años, uso de endoprótesis compuesta por poliester, recubrimiento aórtico ≥ 20cm y tiempo quirúrgico >180 min; (p < 0,05), evidenciando en este grupo de pacientes mayor readmisión, estancia hospitalaria y morbilidad cardiovascular (p < 0,05). Discusión: El síndrome post implantación conduce a una recuperación posoperatoria más exigente, aumentando la morbilidad cardiovascular, readmisión y estancia hospitalaria, con los correspondientes riesgos y costos asociados, en consecuencia podría considerarse una complicación de la reparación aórtica endovascular. Conclusión: La respuesta inflamatoria puede ser intensa posterior a la reparación endovascular de la aorta, el grupo de pacientes que desarrolla este síndrome, amerita una estrecha vigilancia, con énfasis durante el primer mes de post operatorio.
Introduction: Postimplantation syndrome is a common disorder, produced in the immediate postoperative period after endovascular treatment of aortic disease, characterized by anorexia, thoracic or low back pain, leukocytosis, fever and elevation of C-reactive protein, occasionally associated with decreased platelet count or coagulation disorders. Aim: To assess postimplantation syndrome after endovascular aortic repair. Material and Methods: This is an observational, and descriptive study; we analyze the presence of postimplantation syndrome, in 112 successive endovascular repairs of the thoracic and abdominal aorta, over a period of 10 years (2009 to 2019), in the Hospital Dr. Eduardo Pereira in Valparaíso, Chile. Results: 112 endovascular repairs were performed, 81 cases (72.32%) corresponding to EVAR and 31 cases (27.68%) to TEVAR, incidence of post-implantation syndrome was 17.85%. Associated risk factors were age ≤ 75 years, use of polyester stent grafts, aortic covered ≥ 20 cm, surgical time ≥ 180 min, (p < 0.05). As a consequence, in this group of patients, there were associated with greater readmission rates, hospital stay rates and cardiovascular morbidity (p < 0.05). Discussion: The post-implantation syndrome leads to an increase in cardiovascuar morbidy hospital stay rates and a slower postoperative recovery, with the corresponding associated risks and costs, therefore it could be considered a complication of endovascular aortic repair. Conclusion: The inflammatory response after endovascular repair of the aorta, may be intense in some patients, the group of patients who develop this syndrome deserve close monitoring, with emphasis during the first month after surgery.

La candidiasis es una enfermedad micótica debida a levaduras pertenecientes al género Candida. Dentro del gran conjunto de microorganismos que colonizan al ser humano, Candida albicans es el agente etiológico más comúnmente detectado ya que habita como comensal en las superficies mucosas y la piel. C. albicans participa en procesos de fermentación de azúcares y asimilación de nutrientes, pero, en algunas ocasiones se relaciona con procesos patológicos. En los últimos años los avances tecnológicos y médicos; así como el aumento en la incidencia de infecciones por el virus de la inmunodeficiencia humana, el auge creciente de la terapia inmunomoduladora y el uso de antibióticos de amplio espectro durante largos períodos de tiempo se han convertido en los factores de riesgo más importantes para la creciente incidencia de infecciones por microorganismos del género Candida. Debido a esto, resulta imperativo el conocimiento de esta enfermedad y sus formas clínicas más importantes, así como el abordaje diagnóstico y el tratamiento actual; información que recolectamos en este documento para brindar una visión general sobre esta patología(AU)
Candidiasis is a fungal disease caused by yeasts belonging to the genus Candida. Within the large group of microorganisms that colonize humans, candida albicans is the most commonly detected etiological agent since it inhabits mucosal surfaces and skin as a commensal. C. albicans participates in sugar fermentation processes and assimilation of nutrients but, on some occasions, it is related to pathological processes. In recent years, technological and medical advances; As well as the increase in the incidence of human immunodeficiency virus infections, the growing boom in immunomodulatory therapy and the use of broad-spectrum antibiotics for long periods of time have become the most important risk factors for the increasing incidence of infections by microorganisms of the genus Candida. Due to this, knowledge of this disease and its most important clinical forms, as well as the current diagnostic approach and treatment, is imperative; information that we collect in this document to provide an overview of this condition(AU)

ABSTRACT Objective: Cervical spondylotic myelopathy (CSM) is the main cause of spinal dysfunction in adults. The type of surgical approach to treatment is not well defined in the literature. The objective is to report the results obtained through isolated posterior decompression in patients with a previous indication of the combined approach for the treatment of cervical spondylotic myelopathy. Methods: This is a therapeutic study with level of evidence II, according to the Oxford classification table. Ten patients who underwent isolated posterior approach surgery for the treatment of cervical spondylotic myelopathy were evaluated through imaging and questionnaires (visual analog scale, mJOA-Br scale - Brazilian Portuguese version of the Modified Japanese Orthopedic Association Scale, and Neck Disability Index (NDI)), comparing pre- and postoperative results. Results: Late evaluation of the 10 patients was performed in the period ranging from 24 to 36 months (mean of 30.3 months ± 7.25) following surgery. The comparison of the clinical and radiological parameters in all patients showed a statistical difference in relation to the preoperative scales applied and to the degree of cervical lordosis (p <0.05), evidencing improvement after decompression and posterior fixation of the cervical spine. Conclusions: The isolated posterior approach (decompression, fixation and arthrodesis) allowed the clinical and radiological improvement of patients with cervical spondylotic myelopathy and who had an indication of the complementary anterior approach. Level of evidence II; Retrospective study.
RESUMO Objetivo: A mielopatia cervical espondilótica (MCE) é a principal causa de disfunção medular nos adultos. O tipo de abordagem cirúrgica para o tratamento não é bem definido na literatura. O objetivo é relatar os resultados obtidos por meio da descompressão posterior isolada nos pacientes com indicação prévia da abordagem combinada para o tratamento da mielopatia cervical espondilótica. Métodos: Trata-se de um estudo terapêutico com nível de evidência II, conforme a tabela de classificação Oxford. Dez pacientes submetidos apenas à abordagem cirúrgica posterior para tratamento de mielopatia cervical espondilótica foram avaliados por meio de exames de imagem e de questionários (escala visual analógica, escala mJOA-Br - Versão em Português da Escala Modificada da Sociedade Japonesa de Ortopedia e escala de incapacidade cervical - Neck Disability Index - NDI), comparando os resultados pré e pós-operatórios. Resultados: A avaliação tardia dos 10 pacientes foi realizada no período que variou de 24 a 36 meses (média de 30,3 meses ± 7,25) de pós-operatório. A comparação dos parâmetros clínicos e radiológicos em todos os pacientes mostrou diferença estatística com relação ao pré-operatório para as escalas aplicadas e para o grau de lordose cervical (p < 0,05), evidenciando a melhora depois da descompressão e da fixação posterior da coluna cervical. Conclusões: A abordagem posterior isolada (descompressão, fixação e artrodese) permitiu a melhora clínica e radiológica de pacientes com mielopatia cervical espondilótica e que tinham indicação da abordagem anterior complementar. Nível de evidência II; Estudo retrospectivo.

Objetivo : determinar las características sociodemográficas y los modos adaptativos afectados en pacientes diabéticos atendidos en centros de salud del Distrito Chambo-Riobamba. Método : estu- dio con enfoque mixto, descriptivotransversal, en población constituida por 157 pacientes con ECNT, de los centros del Distrito Chambo-Riobamba, Ecuador; seleccionando 40 mayores de 19 años, salud mental apta para llenar los instrumentos, con diagnóstico de diabetes Mellitus tipo II, residencia regular en los sectores mencionados y que estén de acuerdo con participar, durante el período abril-agosto 2017. Resultados : se observó que el 67,5% son de sexo femenino, mayores de 65 años, el 75% con instrucción básica y el 52,5% ama de casa. Tuvieron un 90% en el nivel medio y poca adaptación a las limitaciones por la enfermedad y el 82,5% pocas veces o nunca reali- za actividad física. El 77,5% manifiestó cambios emocionales y en relación con el apoyo familiar se evidenció que el 80% no lo recibió. Conclusiones : las características sociodemográficas distin- tivas en la población de estudio fueron: predominio del género femenino, adultos mayores, amas de casa, de instrucción básica. Tomando en cuenta los modos adaptativos en el fisiológico los pacientes manifiestan poca adaptación a la enfermedad. Mientras que de forma mayoritaria a veces o nunca realizaban actividad física. En el modo psicosocial, el auto-concepto se encuentra alterado; así como en el de interdependencia la mayoría de los individuos a veces o nunca recibían soporte familiar, relacionando con un déficit de búsqueda de sistemas de apoyo y el régimen terapéutico.
Objective: to determine the sociodemographic characteristics and the adaptive modes affected in diabetic patients treated in health centers of the Chambo-Riobamba District during the period April-August 2017. Method: a study with a mixed, descriptive-cross-sectional approach was carried out in a population made up of 157 patients with NCD, they were attended in the centers of the Chambo-Riobamba District, Ecuador. 40 patients over 19 years of age were selected considering aspects such as mental health suitable to fill out the instruments, diagnosed with type II diabetes mellitus, regular residence in the aforementioned sectors and who agree to parti- cipate. Results: it was observed that 67.5% are female, over 65 years of age, 75% have basic education and 52.5% are housewives. They had 90% in the medium level and little adaptation to the limitations due to the disease and 82.5% rarely or never did physical activity. 77.5% mani- fested emotional changes and in relation to family support and 80% did not receive it. Conclu- sions: the distinctive sociodemographic characteristics in the study population were the predo- minance of the female gender, older adults, housewives, basic education. Taking into account the adaptive modes in the physiological, patients showed little adaptation to the disease. Most of them sometimes or never did physical activity. In the psychosocial mode, the self-concept was altered; as well as in the interdependence, most individuals sometimes or never received family support, related to a deficit in the search for support systems and the therapeutic regimen.

Introducción: los tumores en la cavidad nasal y los senos paranasales son un problema serio en la población pediátrica, principalmente por la inespecificidad de los síntomas que lleva a que pasen de meses a años antes de la sospecha de una patología neoplásica, con un impacto en la calidad de vida del paciente y su entorno. Al sospechar de la presencia de un tumor nasosinusal se requiere la realización de imágenes diagnósticas como la resonancia magnética y la tomografía computarizada de los senos paranasales. Cuando se tiene un diagnóstico etiológico, siempre se debe realizar un abordaje multidisciplinario. Materiales y métodos: realizamos un estudio retrospectivo de corte transversal de la cohorte de pacientes con tumores de nariz y senos paranasales atendidos en un hospital pediátrico de cuarto nivel en Bogotá, Colombia, entre 2013-2018. Resultados: se incluyeron un total de 54 pacientes con tumores malignos y benignos de nariz y senos paranasales, la mayoría fueron hombres con un promedio de edad de ocho años. Generalmente se presentaron con síntomas nasosinusales, el principal fue obstrucción nasal en el 80 % de los pacientes. El diagnóstico mas común fue craneofaringioma en un tercio de los pacientes, seguido por angiofibroma nasofaríngeo y linfoma de Burkitt. Conclusión: es importante conocer los síntomas y características clínicas de los pacientes pediátricos con tumores nasofaríngeos. Por esta razón, se considera importante presentar la casuística y características de los tumores de nariz y senos paranasales recogida durante 5 años, en un hospital pediátrico de cuarto nivel en la ciudad de Bogotá, Colombia
Introduction: Tumors in the nasal cavity and paranasal sinuses in children is a serious problem in the pediatric population, mainly due to the non-specificity of the symptoms that leads to years or months passing before the suspicion of a neoplastic pathology. With an important impact in quality of life not only in the patient but also in its family environment. When suspecting a sinonasal tumor, diagnostic images such as magnetic resonance and computed tomography of the paranasal sinuses are required. When you have an etiological diagnosis always do a multidisciplinary approach. Methods: We conducted a cross-sectional study of the cohort of patients that had been diagnose with tumors of the nasal cavity or paranasal sinuses in a fourth level pediatric hospital in Bogota, Colombia between 2013 - 2018. Results: 54 patients were included, the majority of them were men, with an average age of eight years. They mainly presented with nasal symptoms, the main one being nasal obstruction in 80% of patients. The most common diagnosis was cranipharyngioma in one third of the patients, followed by nasopharyngeal angiofibroma and Burkitt lymphoma. Conclusion: We present this article with the objective of presenting the tumors of nose and paranasal sinuses casuistry collected during 5 years in a fourth level pediatric hospital in the city of Bogotá and the imaging characteristics for the diagnosis of these are reviewed with some clinical cases as examples.

Currently, the Patagonian huemul (Hippocamelus bisulcus) is endangered. Anatomical studies focused on understanding the anatomy of the deer most threatened by extinction in South America is a challenge for anatomists, veterinarians and biologists. Research carried out for its conservation has focused mainly on its ecology and pathology, leaving gaps in anatomical knowledge, which is basic and important for a comprehensive understanding of this species. Gross anatomy and radiography of the skeleton of the pelvic limb was performed in three adult Patagonian huemul. Bone specimens of three skeletally mature Patagonian huemul deer were used for gross osteological and radiographic studies. This study was conducted to reveal the morphometric and morphological features of the ossa membri pelvini of the Patagonian huemul. The main findings suggest the presence of powerful extensor muscles in the coxofemoral, femorotibial and tarsal joints, useful during walking, jogging and propulsion in deer. In general, the MNF of Patagonian huemul differ in position with respect to domestic ungulates. In addition, the presence of a notch or obturator canal was observed, with variability in morphology and development among the specimens.
Actualmente, el Huemul Patagónico (Hippocamelus bisulcus) está en peligro de extinción. Los estudios morfológicos centrados en comprender su anatomía han sido un desafío para morfólogos, veterinarios y biólogos. Investigaciones enfocadas en su conservación, se han centrado principalmente en su ecología, patología y en la descripción de sus principales agentes infecciosos, dejando vacíos en el conocimiento anatómico básico, y por ende, su comprensión morfofisiológica. El objetivo de este estudio fue describir la anatomía, morfometría y radiología macroscópica normal y detallada del ossa membri pelvini en tres especímenes de Huemul Patagónico, incluida una interpretación funcional como referencia para uso clínico y conservacionista, investigación biomédica y fines de enseñanza. Los principales hallazgos sugieren la presencia de potentes músculos extensores en las articulaciones coxofemoral, femorotibial y tarsal, útiles durante la marcha, el trote y la propulsión en los ciervos. En general, los forámenes nutricios principales del Huemul patagónico difieren en posición con respecto a los ungulados domésticos. Además, se observó la presencia de una muesca o canal obturador, con variabilidad morfológica y de desarrollo entre los especímenes.

La neuropatía autonómica cardiovascular en el paciente diabético (NACD) se define como una complicación crónica de la diabetes de tipo microangiopática, que se expresa en disautonomía del sistema cardiovascular. Se realizó un estudio descriptivo transversal cuyo objetivo fue la caracterización epidemiológica y clínica de los pacientes diabéticos tipo 2 con NACD que acudieron a la Unidad de Diabetes del CCR-ASCARDIO de la ciudad de Barquisimeto, estado Lara durante el mes de diciembre del año 2014. La muestra estuvo conformada por 68 individuos diabéticos tipo 2, con una prevalencia de NACD según la prueba de RV del 63,2%, por ortostatismo de 45,6% y por taquicardia sinusal inapropiada de 8,8%. Hubo un predominio del género femenino y un mayor porcentaje de pacientes con NACD no tenían control metabólico de la diabetes y tenían más de 5 años con la enfermedad. En conclusión, se sugiere el diagnóstico precoz de la DM así como la identificación temprana de síntomas que sugieran el desarrollo de disautonomía por deterioro neuropático del sistema cardiovascular en estos pacientes(AU)
Cardiovascular autonomic neuropathy in diabetic patients (CAN) is defined as a chronic complication of diabetes (DM) of the microangiopathic type, which is expressed as dysautonomia of the cardiovascular system. We performed an observational descriptive cross-sectional study to characterize clinically and epidemiologically type 2 diabetic patients with CAN that were attended in December 2014 at the Unidad de Diabetes of CCR-ASCARDIO in Barquisimeto, Lara state. The sample consisted of 68 type 2 diabetic patients with a prevalence of CAN according to the RINES VALCARDI (RV) test of 63.2%, by orthostatism of 45.6% and by the presence of inappropriate sinus tachycardia of 8.8%. In patients with CAN, there was female predominance and a greater percentage of patients had more than five years with diabetes and no metabolic control their disease. In conclusion, it is important to make an early diagnosis of diabetes and clearly identify symptoms that suggest dysautonomia in these patients(AU)

Desarrollar un programa de salud mental Infanto-juvenil es complejo, por la multiplicidad de variables implicadas y la dificultad para integrarlas. Son muchos los sectores de la sociedad que juegan un rol determinante en el desarrollo infantil, lo que complejiza la generación de un diálogo integrador y efectivo entre ellos hacia un fin común, la salud mental. En el artículo se analiza la aplicación del modelo ecológico de Bronfenbrenner en la organización de salud mental de nuestro país. Planteamos que a través de él es posible ampliar la mirada y la comprensión de la complejidad del fenómeno de salud mental Infanto juvenil, facilitando el desarrollo de propuestas de intervención que incorporen la mayoría de las variables e intersectores intervinientes, como, salud, educación, Servicio nacional de menores (Sename), justicia, entre otros, y por supuesto la comunidad en general, como actores relevantes y determinantes sociales en el proceso salud cuidadosenfermedad.
Developing a mental health program for children and adolescents is very complex, due to the multiplicity of variables involved and the difficulty in integrating them. There are many sectors of our society that play a decisive role in child development, which complicate the generation of an inclusive and effective dialogue between them towards a common goal, mental health. The article analyzes the application of the ecological model of Urie Bronfenbrenner in the organization of public health and mental health in our country. We propose that through it, it is possible to broaden the view and understanding of the complexity of the mental health phenomenon for children and young people, facilitating the development proposals that incorporate most of the intervening variables and intervention target areas, such as health, education, Sename, justice, among others, and of course the community in general, as relevant actors and social determinants in the health- care-disease process.

Fundamento: A remodelagem cardíaca depende da intensidade, da duração e do método de treinamento. Objetivo: Avaliar se o treinamento realizado em uma tropa especial portuguesa incrementa a remodelagem cardíaca em uma amostra de jovens que previamente praticavam esporte de competição. Métodos: Estudo prospectivo que incluiu 76 militares candidatos a tropas especiais, 45 dos quais praticavam previamente exercício físico de nível competitivo (> 10 horas por semana). Destes militares atletas, apenas 17 concluíram com sucesso o curso. A avaliação foi realizada com 6 meses de intervalo e incluiu história clínica completa, exame físico, sinais vitais, dados antropométricos e avaliação ecocardiográfica. Considerou-se significância estatística quando p < 0,05, com intervalo de confiança de 95%. Resultados: No final do curso, verificaram-se diminuição da porcentagem de massa gorda (19,1 ± 3,3% vs. 13,1 ± 3,5%; p < 0,01), aumento da porcentagem de massa muscular (41,3 ± 2,1% vs. 44,4 ± 1,8%; p < 0,01), e diminuição da pressão arterial sistólica, diastólica e frequência cardíaca. Em relação à remodelagem cardíaca, verificaram-se aumento do diâmetro diastólico do ventrículo esquerdo (49,7 ± 3,2 mm vs. 52,8 ± 3,4 mm; p < 0,01), aumento tendencial do volume do átrio esquerdo (27,3 ± 4,5 mL/m2 vs. 28,2 ± 4,1 mL/m2; p = 0,07) e aumento da massa do ventrículo esquerdo (93,1 ± 7,7g/m2 vs. 100,2 ± 11,4 g/m2; p < 0,01). As variáveis funcionais também sofreram alterações, com aumento do S' (15 (13-16) cm/s vs. 17 (16-18) cm/s; p < 0,01) e diminuição da fração de ejeção do ventrículo esquerdo (60 ± 6% vs. 54 ± 6%; p < 0,01). Conclusão: O treinamento físico militar intenso provocou remodelagem cardíaca adicional em atletas de nível competitivo, tanto estrutural como funcional
Background: Cardiac remodeling depends on the intensity, duration, and training method. Objective: To evaluate if the training performed in a Portuguese military special operations troop increases cardiac remodeling in a sample of young individuals who previously practiced competitive sports. Methods: A prospective study involving 76 military candidates for military special operations, 45 of whom previously practiced at competitive level (> 10 hours per week). Of these military athletes, only 17 successfully completed the course. The evaluation was performed at 6 months intervals and included a complete clinical history, physical examination, vital signs, anthropometric data and echocardiographic evaluation. Statistical significance was considered when p < 0.05, with a 95% confidence interval. Results: At the end of the course, there was a decrease in the percentage of fat mass (19.1 ± 3.3% vs. 13.1 ± 3.5%; p < 0.01), an increase in the percentage of lean mass (41.3 ± 2.1% vs. 44.4 ± 1.8%; p < 0.01), and decreased systolic and diastolic blood pressure and heart rate. Regarding cardiac remodeling, there was an increase in left ventricular diastolic diameter (49.7 ± 3.2 mm vs. 52.8 ± 3.4 mm; p < 0.01), an increase trend in left atrial volume (27.3 ± 4.5 mL/m2 vs. 28.2 ± 4.1 mL/m2; p = 0.07) and increased left ventricular mass (93.1 ± 7.7 g/m2 vs.100.2 ± 11.4 g/m2 ; p < 0.01). Functional variables also changed, with an increase in S' (15 (13-16) cm/s vs. 17 (16-18) cm/s; p < 0,01) and a decrease in left ventricular ejection fraction (60 ± 6% vs. 54 ± 6%; p < 0.01). Conclusion: Intense military physical training resulted in additional cardiac remodeling in athletes of competitive level, both structural and functional

Resumen Los trastornos de la conducta alimentaria (TCA) son trastornos mentales caracterizados por la alteración del patrón de ingesta calórica. A su vez, los TCA presentan una alta comorbilidad con la depresión y la ansiedad. En México, la Escala Hospitalaria de Ansiedad y Depresión (HADS) ha mostrado ser un instrumento de evaluación válido y confiable en pacientes con VIH, cáncer u obesidad, pero no se han examinado sus propiedades psicométricas en pacientes con TCA, siendo este el objetivo del presente trabajo. Participaron 325 pacientes (M edad = 22.0, DE =9.7), quienes completaron la HADS. Con base en el análisis de componentes principales, con rotación oblimin, la escala quedó conformada por 12 reactivos divididos en las dos subescalas predichas: Depresión (con nueve ítems) y Ansiedad (con tres ítems). Con base en esta estructura, se confirmó la consistencia interna tanto de la escala (α = 0.88) como de sus dos subescalas (α > 0.80). Sin embargo, los reactivos no se agruparon de forma similar a la escala original, por lo que se analiza en detalle la reconfiguración de la HADS a la luz de las características de la población con TCA en que se examinó la escala.
Abstract Eating disorders (ED) are psychiatric diseases characterized by the alteration of the caloric intake. Besides, ED have a high comorbidity with depression and anxiety. In Mexico, the Hospital Anxiety and Depression Scale (HADS) has shown to be a valid and reliable instrument in patients with HIV, cancer, and obesity but its psychometric properties have not been assessed in patients with ED, being the latter the aim of this research. A total of 325 patients (M age = 22.0, SD = 9.7), completed the HADS. Based on principal axis factoring and oblimin rotation the scale yielded 12 items divided into two subscales: Depression (with nine items) and Anxiety (with three items). With this structure was confirmed the internal consistency of the scale (α = 0.88) and the two subscales (α > 0.80), however the items did not group in the same order than they did in the original scale, for this reason the new configuration of the HADS was analyzed in detail based on the features of the population where the scale was examined, this means, in patients with ED.

RESUMO
ABSTRACT Extranodal natural killer (NK)/T-cell lymphoma, nasal type, is a rare entity in otorhinolaryngology. Its management requires skilled physicians in order to suspect this disease and making a proper diagnosis at early stages. This paper reports the case of a 31-year-old male patient, with one month of nasal obstruction, recurrent sinusitis, palatal ulceration and a necrotizing lesion. Histopathology reported lymphoid infiltrate polymorph angiocentric growth pattern and extensive areas of necrosis. Immunohistochemistry confirmed the phenotype for T/NK cells: positive CD3, BCL2, CD4 and CD56. IgG for Epstein-Barr virus was also positive. The initial staging was T4, N1, M0, Eastern Cooperative Oncology Group (ECOG) scale was 1, with intermediate risk, and low International Prognostic Index (IPI); based on this results, the patient was referred to oncology to initiate treatment. After a ten-month follow-up, the patient's condition improved, with complete remission of nasal and palate injuries; no relapse has occurred to date. This case is a clear example of the importance of early diagnostic through multiple biopsies in order to establish a specific treatment to decrease complication rates and improve prognosis.
