Displasia congénita de tibia : 12 años de seguimiento
Congenital dysplasia of the tibia, previously named congenital pseudoarthrosis, is a very rare disorder, affecting 1 in 140,000 live-born children. Some of those cases are associated with neurofibromatosis or Von Recklinghausen disease and involvement of the fibula has been reported in 62% of cases . The diagnosis is usually made at birth. The natural history of the disease is extremely dark and once a fracture occurs, there is no tendency to heal spontaneously. We would like to report a 12 years followed-up case, treated with different methods with the aim of revise different treatment techniques depending on the age of the patient and the kind of fracture
Linking of psoriasis with osteopenia and osteoporosis: A cross‑sectional study
Psoriasis is a multisystem disease which has been related to vitamin‑D
deficiency through chronic inflammation. This psoriasis‑related inflammatory state and vitamin‑D
deficiency may induce bone mineral density loss. The purpose of this study is to assess the relationship
of psoriasis with bone mineral density, by comparing psoriatic patients with healthy controls and patients
with osteopenia/osteoporosis. Psoriatic patients showed worse hip and lumbar spine bone mineral density levels than
healthy controls (P = 0.001) and better levels than osteoporotic patients (P < 0.001). Multivariate analysis
demonstrated a negative association of age and a positive association of body mass index in hip bone
mineral density in psoriatic patients. Bone mineral density levels in psoriatic patients are situated halfway between healthy
controls and patients with osteopenia/osteoporosis. In addition, the higher body mass index in patients with
psoriasis appears to confer a protective effect against further development of lower bone mineral density
Relationship between the two-component system 1-Br-adamantane + 1-Cl-adamantane and the high-pressure properties of the pure components
The temperature-composition phase diagram of the two-component system 1-Br-adamantane and 1-Cl-adamantane has been determined by means of thermal analysis techniques and X-ray powder diffraction from the low-temperature phase to the liquid state.
The crossed isopolymorphism formalism has been applied to the two-component system to infer the normal pressure properties of the orthorhombic metastable phase of 1-Cl-adamantane at normal pressure. The experimental pressure-temperature phase diagrams for the involved compounds are related to the two-phase equilibria determined at normal pressure and inferences about the monotropic behavior of the aforementioned orthorhombic phase are discussed.Peer ReviewedPostprint (author's final draft
TGFβ Governs the Pleiotropic Activity of NDRG1 in Triple-Negative Breast Cancer Progression
In triple-negative breast cancer (TNBC), the pleiotropic NDRG1 (N-Myc downstream regulated gene 1)
promotes progression and worse survival, yet contradictory results were documented, and the mechanisms
remain unknown. Phosphorylation and localization could drive NDRG1 pleiotropy, nonetheless, their role in
TNBC progression and clinical outcome was not investigated. We found enhanced p-NDRG1 (Thr346) by
TGFβ1 and explored whether it drives NDRG1 pleiotropy and TNBC progression. In tissue microarrays of 81
TNBC patients, we identified that staining and localization of NDRG1 and p-NDRG1 (Thr346) are biomarkers
and risk factors associated with shorter overall survival. We found that TGFβ1 leads NDRG1, downstream of
GSK3β, and upstream of NF-κB, to differentially regulate migration, invasion, epithelial-mesenchymal transition,
tumor initiation, and maintenance of different populations of cancer stem cells (CSCs), depending on the
progression stage of tumor cells, and the combination of TGFβ and GSK3β inhibitors impaired CSCs. The
present study revealed the striking importance to assess both total NDRG1 and p-NDRG1 (Thr346)
positiveness and subcellular localization to evaluate patient prognosis and their stratification. NDRG1
pleiotropy is driven by TGFβ to differentially promote metastasis and/or maintenance of CSCs at different
stages of tumor progression, which could be abrogated by the inhibition of TGFβ and GSK3β.Instituto de Salud Carlos III

Role of age and comorbidities in mortality of patients with infective endocarditis
[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality.
[Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk.
[Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality.
[Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
Manual de simulación clínica en especialidades médicas
Manual sobre técnicas y modos de simulación clínica en diversas especialidades médicas.La enseñanza y formación en medicina necesita el uso de la simulación. Existen evidencias de su uso desde hace cientos de años, pero, en los últimos años se ha incrementado y diseminado.
La simulación clínica está validada científicamente en múltiples contextos médicos y de otras áreas profesionales de la salud. Y es considerada de gran importancia como proceso de entrenamiento y de mejora de las competencias y adquisición de habilidades médicas en campos que incluye desde la historia clínica, comunicación con el paciente, exploración, diagnóstico terapéutica médica-farmacológica y quirúrgica y seguridad al tratar al paciente.
Hoy en día, para muchas técnicas y situaciones clínicas es inaceptable llegar junto a los pacientes sin un dominio adquirido en simulación. La simulación puede ocurrir sin el uso de recursos adicionales, solo las personas, o utilizando pocos o muchos recursos de baja hasta alta tecnología y se puede adaptar a los recursos disponibles, abarcando todas las áreas de conocimiento, y dentro de ellas competencias técnicas o actitudes, solas o en conjunto.
El uso racional y basado en evidencia de la simulación es de la mayor importancia por la necesidad de una mayor efectividad y eficiencia en la transformación de los profesionales de la salud para que puedan mejorar su capacidad de atender a los pacientes.
La simulación es también una buena herramienta de evaluación de competencias y habilidades en Medicina y otras disciplinas de las Ciencias de la Salud
