Association of polymorphisms rs2303729, rs10880, and rs1131620 of LTBP4 with sarcopenia in elderly patients with type 2 diabetes mellitus.

BACKGROUND: Latent TGFß binding protein 4 (LTBP4) modifies skeletal muscle function, and polymorphisms in this gene have been associated with a longer ambulation time in patients with Duchenne muscular dystrophy. However, no studies associate these polymorphisms with an acquired muscle condition. AIM: The study aims to determine whether three functional variants within the LTBP4 were associated with sarcopenia in patients with type 2 diabetes mellitus (T2DM). SUBJECTS AND METHODS: We performed an analysis with 144 elderly individuals with T2DM, including 101 without sarcopenia and 43 with sarcopenia. Polymorphism frequency was determined by real-time PCR allelic discrimination TaqMan assay. RESULTS: Under different genetic models, the univariant analysis did not show a significant association of any polymorphism with sarcopenia. But the multivariate model analysis showed that variant rs1131620 (OR 7.852, 95% CI 1.854-33.257, p = 0.005) was significantly associated with sarcopenia under a dominant model. Under the same analysis, the variants rs2303729 and rs10880 had a more discrete association (OR 3.537 95% CI 1.078-11.607, p = 0.037; OR 5.008, 95% CI 1.120-22.399, p = 0.035, respectively). CONCLUSIONS: Our study highlights the importance of studying LTBP4 polymorphisms associated with sarcopenia. These findings suggest that the rs1131620 polymorphism of the LTBP4 may be part of the observed sarcopenia process in patients with T2DM.

[Integrated Care Protocol: Hypertension]. / Protocolo de Atención Integral: hipertensión arterial sistémica.

Background: Hypertension is the most common cardiovascular risk factor that is responsible for complications such as cerebrovascular events, heart failure, acute myocardial infarction, kidney failure, arrhythmias and blindness. About 30% of the adult population older than 20 years is a carrier. 40% of carriers are unaware of suffering from it since its onset is generally asymptomatic. Unfortunately, of those who are already known to be hypertensive, only half take drug treatment and of these, only half achieve control figures (<14/90 mmHg). For several decades it has not been possible to forcefully modify the natural history of this disease despite the advancement of therapeutic drugs. The Mexican Institute of Social Security launches the initiative of the Integrated Care Protocols (PAI) of the main diseases. This protocol shows how the three levels of medical care are concatenated, the role of each of the members of the multidisciplinary team for medical care, including: doctor, nurse, social work, psychologist, nutritionist, among others and, to patient sharing. The main changes in diagnostic criteria, in-office and out-of-office blood pressure measurement, drug therapy (monotherapy, dual therapy and triple therapy) and non-drug therapy, and follow-up are presented. The diagnostic-therapeutic approach using algorithm as well as the diagnostic approach to secondary hypertension and special forms of hypertension such as in pregnancy, hypertensive crisis, hypertension in the elderly, ischemic or nephropathy patients.

Introducción: la hipertensión arterial sistémica (HAS) es el factor de riesgo cardiovascular más común y es responsable de complicaciones como evento cerebrovascular, insuficiencia cardiaca, infarto agudo de miocardio, insuficiencia renal, arritmias y ceguera. Alrededor del 30% de la población adulta mayor de 20 años es portadora. El 40% de los portadores ignoran padecerla ya que su inicio generalmente es asintomático. Desafortunadamente de los que ya se saben hipertensos solo la mitad toma tratamiento farmacológico y de estos, tan solo la mitad logra cifras de control (< 140/90 mmHg). Durante varias décadas no se ha logrado de forma contundente modificar la historia natural de esta enfermedad pese al avance fármaco terapéutico. El Instituto Mexicano del Seguro Social, lanza la iniciativa de los Protocolos de Atención Integral (PAI) de las principales enfermedades. En el presente protocolo se muestra cómo se concatenan los tres niveles de atención médica, el papel de cada uno de los integrantes del equipo multidisciplinario para la atención médica, incluyendo: médico, enfermera, trabajo social, psicólogo, nutricionista, entre otros y, la coparticipación del paciente. Se presentan los principales cambios en criterios diagnósticos, medición de la presión arterial dentro y fuera de consultorio, terapéutica farmacológica (monoterapia, terapia dual y terapia triple), no farmacológica y seguimiento. El Abordaje diagnóstico-terapéutico usando algoritmos, así como también el abordaje diagnóstico de la hipertensión secundaria y formas especiales de hipertensión tales como en el embarazo, crisis hipertensivas, hipertensión en el adulto mayor, pacientes isquémicos o con nefropatía.
