ABSTRACT

Aims: To quantify total glycogen synthase kinase (GSK)-3β and GSK-3β phosphorylated at serine 9 in the peripheral blood mononuclear cells from Amyotrophic Lateral Sclerosis (ALS) patients and to assess if GSK-3β could be a biomarker for ALS. Study Design: Cross-sectional observational study. Place and Duration of Study: Department of Immunology and Amyotrophic Lateral Sclerosis Unit, Hospital Carlos III, Madrid, Spain, between February 2011 and August 2012. Methodology: Blood samples were drawn from 44 ALS patients and 41 healthy controls. Peripheral blood mononuclear cells were isolated and cellular extracts were obtained to assess GSK-3β and serine 9 phosphorylated GSK-3β concentrations. Enzymes were measured by a quantitative enzyme-linked immunoassay in the peripheral blo mononuclear cell extracts. Patients were divided into two groups according to the Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-R) median value for the comparative analysis. Results: Patients (n=22) showing a high functional impairment (ALSFRS-R ≤ 32) had GSK-3β levels (11.2±3.6 pg/μg protein) higher than healthy controls (8.7±4.7 pg/μg protein; P=0.04) and than those patients (n=22) with ALSFRS-R > 32 (6.9±4.4 pg/μg protein; P<0.01). A negative correlation between GSK-3β concentration and ALSFRS-R values (r = −0.39; P=0.006) was also observed. Conclusion: Our results show that GSK-3β expression is altered in non-neural cells of ALS patients and suggest that its overexpression may play a role in the pathogenesis of ALS. The quantification of GSK-3β in peripheral blood mononuclear cells may be used as a potential biomarker of ALS progression.

ABSTRACT

La ventilación mecánica no invasiva (VMNI) incluye una serie de técnicas encaminadas a aumentar la ventilación alveolar sin tener que colocar un tubo endotraqueal o utilizar una traqueotomía. Objetivo: se realizó un estudio explicativo con el objetivo de describir los resultados de la VMNI, en adición al tratamiento médico convencional de los pacientes portadores de agudización grave de Enfermedad Pulmonar Obstructiva Crónica (EPOC) y Edema Agudo del Pulmón Cardiogénico (EAPC), que ingresaron en la Unidad de Cuidados Intensivos Emergentes (UCIE) del Hospital Militar Clínico Quirúrgico Docente “ Dr. Octavio de la Concepción y de la Pedraja de Camagüey, desde enero hasta diciembre de 2007. Método: el universo se constituyó por la totalidad de los pacientes ingresados con dichos diagnósticos. El 62,06% constituyo la muestra, los cuales cumplieron con los requisitos establecidos para recibir dicho tratamiento. Resultados: El índice de fracaso fue de 16,67%. Las complicaciones presentadas fueron el enrojecimiento de la piel y la distensión gástrica. Se produjo una reducción de la estancia en UCIE de 2h. Conclusiones: el uso de la VMNI mejora la supervivencia de los pacientes al reducir las complicaciones respiratorias.


The non invasive mechanical ventilation (NIMV) includes a serie of techniques guided to increase the alveolar ventilation without having to place an endotracheal tube or to use a tracheotomy. Objective: To describe the results of NIMV, with continuous positive airway pressure (CPAP), in addition to the conventional medical treatment of the patient carrier of serious chronic obstructive pulmonary disease (COPD) and acute edema of the cardiogenic lung (AECL) that were admitted in the Emergent Intensive Care Unit (EICU) of the Surgical Educational Military Clinical Hospital “Dr. Octavio de la Concepción y de la Pedraja” of Camagüey, from January to December 2007. Method: A logitudfinal and prospective explanatory study was carried out. The universe was conformed by the entirety of the patients admitted with this diagnoses. The 62,06% constitutes the sample, which fulfilled the established requirements to receive this treatment. Results: The index of failure was of 16,67%. The presented complications were the skin redness and the gastric distension. A reduction of the stay in the EICU of 2 hours occured. Conclusions: The use of NIMV improves the patients´ survival when reducing the respiratory complications.

ABSTRACT

Fundamento: Las enfermedades del corazón constituyen la principal causa de muerte en los países industrializados y dentro de ellas la cardiopatía isquémica con su complicación más letal, el infarto agudo del miocardio. Objetivo: Evaluar los resultados del tratamiento trombolítico en pacientes mayores de 60 años con diagnóstico clínico-electrocardiográfico de infarto agudo del miocardio. Método: Se realizó un estudio descriptivo retrospectivo desde enero de 2003 hasta diciembre de 2007 a los pacientes que ingresaron en la Unidad de Cuidados Intensivos del Hospital Militar Clínico Quirúrgico Docente «Dr. Octavio de la Concepción y de la Pedraja¼ con diagnóstico clínico electrocardiográfico de infarto agudo del miocardio. La muestra estuvo conformada por 45 pacientes ingresados con este diagnóstico, para lo cual se revisaron las historias clínicas y los expedientes de necropsias en los casos de fallecidos. Se realizó trombolisis al 62,22% de los pacientes. Resultados: En el grupo étareo entre 60 y 79 años fue más frecuente la trombolisis con 12 pacientes. La mortalidad global fue de seis pacientes, con un predominio en el grupo de edad entre 70 y 79 años con tres casos. La causa más frecuente que impidió la trombolisis fue el infarto de más de 12h de evolución con 13 pacientes (28,88%). La reacción adversa más frecuente fue la hipotensión arterial con 15 pacientes para un (15,55%). Conclusiones: La trombolisis en el anciano resultó beneficiosa y en ausencia de contraindicaciones no existen motivos en nuestro medio para su exclusión.


Background: Heart diseases constitute the main cause of death in industrialized countries and among them the ischemic heart disease with its deadlier complication, the acute myocardial infarction. Objective: To evaluate the results of the thrombolytic treatment in patients older than 60 years with clinical-electrocardiographic diagnosis of acute myocardial infarction. Method: A descriptive retrospective study was performed from January 2003 to December 2007 to the patients that were admitted in the Intensive Care Unit at "Dr. Octavio de la Concepción y de la Pedraja" Educational Surgical Clinical Military Hospital with clinical-electrocardiographic diagnosis of acute myocardial infarction. Forty-five patients admitted with this diagnosis constituted the sample, for which medical and necropsy records were revised in dead cases. Thrombolysis to the 62.22% of the patients was carried out. Results: In the age group between 60 and 79 years the thrombolysis was the most frequent with 12 patients. The global mortality was about six patients, where the age group between 70 and 79 years predominated with three cases. The most frequent cause that impeded the thrombolysis was the heart attack of more than 12h of evolution with 13 patients (28,88%). The most frequent adverse reaction was the low blood pressure with 15 patients for a (15,55%). Conclusions: The thrombolysis in elderly turned out to be beneficial and in absence of contra-indications there is no motives in our medium for its exclusion.
