Exposición pre y postnatal a mercurio y presión arterial en preescolares
2019
Antecedentes y objetivos Según la Organización Mundial de la Salud, el mercurio es uno de los diez principales productos químicos o grupos de productos que son motivo de preocupación para la salud pública. La presión arterial sistólica elevada es el principal factor de riesgo de enfermedad y muerte por cualquier causa, y es modificable. La investigación en modelos animales ha encontrado elevaciones en la presión arterial sistólica tras exposiciones a metilmercurio, la forma química del mercurio más tóxica. En población adulta se ha encontrado una relación dosis-respuesta entre la exposición postnatal a mercurio y el riesgo de hipertensión arterial, no lineal, con un cambio de tendencia alre…
Cambios en la expresión de adrenoceptores y GRK en insuficiencia cardiaca e hipertensión arterial
2015
En la insuficiencia cardiaca humana, se ha observado una disminución en la expresión de los adrenoceptores β1 (AR-β1) junto con un aumento de la expresión/función de la cinasa GRK2, pero los cambios en la expresión de otros AR y GRK no han sido establecidos. Otra cuestión sin resolver es la incidencia de estos mecanismos en función de la etiología y el tratamiento de la insuficiencia cardíaca. Queda también por determinar la existencia de un patrón transcripcional común que regula los niveles de ARNm de cada isoforma de GRK y los subtipos de AR-β. Para analizar estas cuestiones, hemos cuantificado la expresión de ARNm y proteína de seis AR (α1A, α1B, α1D, β1, β2 y β3) y tres GRKs (GRK2, GRK…
Standalone sauna vs exercise followed by sauna on cardiovascular function in non‐naïve sauna users: A comparison of acute effects
2021
Background and aimsSauna bathing and aerobic exercise have each been shown to affect cardiovascular function. However, direct comparisons between standalone sauna bathing and a combination of exercise and sauna on vascular indices remain limited. Therefore, we conducted a cross-over study using matched durations to explore the hemodynamic changes of sauna exposure when compared to a combination of aerobic exercise and sauna exposure.MethodsParticipants (N = 72) with at least one cardiovascular risk factor underwent, on two separate occasions: (a) a 30-minute sauna at 75°C (SAUNA) and (b) the combination of a 15-minute cycling exercise at 75% maximum heart rate followed by 15-minute sauna ex…
Changes in Perfusion Pattern of Experimental Tumors Due to Reduction in Arterial Oxygen Partial Pressure

Low-dose rivaroxaban plus aspirin in older patients with peripheral artery disease undergoing acute limb revascularization: insights from the VOYAGER…
2021
Abstract Aims In this secondary analysis of the VOYAGER trial, rivaroxaban 2.5 mg twice/day plus aspirin 100 mg/day was assessed in older adults. Advanced age is associated with elevated bleeding risk and unfavourable net benefit for dual antiplatelet therapy in chronic coronary artery disease. The risk–benefit of low-dose rivaroxaban in patients ≥75 years with peripheral artery disease (PAD) after lower extremity revascularization (LER) has not been described. Methods and results The primary endpoint was a composite of acute limb ischaemia, major amputation, myocardial infarction, ischaemic stroke, or cardiovascular death. The principal safety outcome was thrombolysis in myocardial infarct…
Insufficienza renale acuta in paziente con carcinoma epatocellulare sottoposto a chemioembolizzazione transarteriosa
2007
Transarterial chemoembolization (TACE) is included among the wide therapeutic tools for the treatment of hepatocellular carcinoma (HCC), tumour with high frequency and malignancy. The approach is invasive and, beyond the discomfort for the patient, it is charged by a number of side effects and complications. In this study we report the case of renal acute failure of hypovolemic origin, as a consequence of a TACE in a patient suffering from HCC, occurred after one week of intervention. The different possible mechanisms involved in the pathogenesis of this complication are discussed.
Arterial Embolism to the Upper Extremity in a Patient with Factor V Leiden Mutation (APC Resistance)
2003
Factor V Leiden mutation has emerged as one of the leading abnormalities in inherited blood coagulation disorders, resulting in a markedly increased risk for deep leg vein thrombosis. A 24- year-old woman presented with acute onset of critical ischemia of her left thumb and index finger. Intraarterial angiography revealed an embolus in the distal radial artery and a thrombotic occlusion of the digital artery of the thumb and index finger. Immediate therapy encompassed a selective surgical embolectomy of the distal radial artery followed by a local intraarterial lysis that was continued for 3 days. Additionally, therapeutic anticoagulation and vasodilating drugs (prostaglandin E) were admin…
Validation of the SNACOR clinical scoring system after transarterial chemoembolisation in patients with hepatocellular carcinoma
2017
Abstract Background Transarterial chemoembolisation is the standard of care for intermediate stage (BCLC B) hepatocellular carcinoma, but it is challenging to decide when to repeat or stop treatment. Here we performed the first external validation of the SNACOR (tumour Size and Number, baseline Alpha-fetoprotein, Child-Pugh and Objective radiological Response) risk prediction model. Methods A total of 1030 patients with hepatocellular carcinoma underwent transarterial chemoembolisation at our tertiary referral centre from January 2000 to December 2016. We determined the following variables that were needed to calculate the SNACOR at baseline: tumour size and number, alpha-fetoprotein level,…
