Risk Factors Associated with Mild Cognitive Impairment ?mong Apparently Healthy People and the Role of MicroRNAs

SUMMARY

BACKGROUND: Mild cognitive impairment (MCI) is a stage between the expected cognitive decline of normal ageing and the serious decline of dementia.AIM: To identify risk factors and role of miRNAs associated with mild cognitive impairment (MCI) among employees.SUBJECTS AND METHOD: A cross-sectional study was carried out on 186 employees aged between 40 and 65 years. Cognitive function was evaluated using ACEIII, MoCA, and Quick cognitive tests. Medical history and lifestyle were assessed. Family 132 & 134 miRNA expressions were assessed by real-time PCR.RESULTS: MCI was detected among 14 / 186 (7.5%). miRNA 132 expression was the only significant miRNAs to detect MCI with low sensitivity and specificity (70%). The logistic analysis revealed that higher miRNA132 expressions, low monthly intake of; vegetables, unroasted nuts, low education and higher ALT levels were predicting factors for MCI with AOR 1.1 (1.01-3.3), 1.2 (1.04-1.43), 0.8 (0.8-0.98), 2.7 (1.9-7.4) and 1.6 (1.1-2.3) respectively.CONCLUSION: MiRNAs expression showed low sensitivity and specificity in detecting MCI; only miRNA 132 might be used. Several modifiable factors seem to reduce the risk of MCI.

Caracterización de pacientes con Enfermedad Pulmonar Obstructiva Crónica bajo tratamiento con ventilación mecánica no invasiva Caracterización de pacientes con Enfermedad Pulmonar Obstructiva Crónica bajo tratamiento con ventilación mecánica no invasivaIntroducción: la Enfermedad Pulmonar Obstructiva Crónica es una enfermedad respiratoria caracterizada esencialmente por una limitación crónica al flujo aéreo que no es totalmente reversible, y que se manifiesta en forma de disnea, por lo general progresiva. Como alternativa de tratamiento se encuentra el uso de la ventilación mecánica no invasiva. Objetivo: caracterizar a los pacientes con Enfermedad Pulmonar Obstructiva Crónica sometidos a ventilación mecánica no invasiva ingresados en Unidades de Atención a pacientes graves. Material y métodos: se realizó un estudio descriptivo, retrospectivo, transversal en dos Unidades de Atención a pacientes graves, donde se seleccionó una muestra de 52 pacientes con diagnóstico de Enfermedad Pulmonar Obstructiva Crónica exacerbada severa bajo tratamiento con ventilación mecánica no invasiva. Se estudiaron las variables: edad, sexo, comorbilidades, hábito de fumar y principales causas de agudización. Resultados: el grupo de edad predominante fue el de 51 a 70 años y el sexo masculino. Las comorbilidades más frecuentes fueron el mal estado nutricional, seguido de la hipertensión arterial y la Diabetes mellitus. Se comprobó una asociación entre la hipertensión arterial y la Cardiopatía isquémica, así como entre la hipertensión arterial y el hábito de fumar. El 90,4 % de los pacientes estudiados eran fumadores. Conclusiones: los factores de riesgo predominantes fueron el mal estado nutricional, seguido de la hipertensión arterial y la Diabetes mellitus; sin embargo, el aspecto más preocupante fue la presencia del hábito de fumar, debido a las fatales consecuencias para la salud que tiene este nocivo hábito.Palabras clave: ventilación mecánica no invasiva, Enfermedad Pulmonar Obstructiva Crónica, factor de riesgo, unidades de atención al grave, inflamación, afección sistémica.ABSTRACTIntroduction: Chronic Obstructive Pulmonary Disease is a respiratory disease mainly characterized by a chronic limitation of the air flow which is not irreversible totally and it is clinical generally expressed by progressive dyspnea. Non-invasive mechanic ventilation is used like alternative treatment. Objective: to characterize patients with Chronic Obstructive Pulmonary Disease under non- invasive mechanical ventilation admitted at Critical Care Units. Material and Methods:  cross section retrospective and descriptive trial in two Critical Care Units was performed; it was selected 52 patients with exacerbated severe Chronic Obstructive Pulmonary Disease under non-invasive mechanic ventilation. The variables studied were age, gender, comorbidities, smoke habit and main acute causes. Results: prevail group according to age was from 51 to 70 years old and the gender was male. The most frequent comorbidities were the bad nutritional status, following by hypertension and Diabetes Mellitus. The association between hypertension and ischemic cardiopathy was proved as well as between hypertension and smoke habit. 90.4% of patients were smokers. Conclusions: the prevailed risk factors were the bad nutritional status, following by hypertension and Diabetes Mellitus, whereas, the most concerned aspect was the prevalence of smoke habit because the fatal health consequence that  it harmful  habit has.Key words: Non-invasive mechanical ventilation. Chronic Obstructive Pulmonary Disease, risk factor, Critical Care Unit, inflammation, systemic complaint.
