Guía de práctica clínica mexicana para el diagnóstico y tratamiento de las dislipidemias y enfermedad cardiovascular aterosclerótica.

Antecedentes: Las enfermedades cardiovasculares son la principal causa mundial de mortalidad y México no es la excepción. Los datos epidemiológicos obtenidos en 1990 mostraron que los padecimientos cardiovasculares representaron el 19.8% de todas las causas de muerte en nuestro país; esta cifra se incrementó de manera significativa a un 25.

Neurological manifestations temporally associated with SARS-CoV-2 infection in pediatric patients in Mexico.

Purpose: To describe the temporal association of specific acute neurological symptoms in pediatric patients with confirmed SARS-CoV-2 infection between May and August 2020.

Methods: We performed a recollection of all the clinical and laboratory data of patients having acute neurological symptoms temporally associated with SARS-CoV-2 infection at a third-level referral hospital in Mexico City (Instituto Nacional de Pediatría). Patients in an age group of 0-17 years with acute neurological signs (including ascending weakness with areflexia, diminished visual acuity, encephalopathy, ataxia, stroke, or weakness with plasma creatinine kinase (CK) elevation) were evaluated.

Association of mitochondrial variants A4336G of the tRNAGln gene and 8701G/A of the MT-ATP6 gene in Mexicans Mestizos with Parkinson disease.

Introduction: Sporadic Parkinson's disease (PD) is a neurodegenerative disorder of unknown etiology. In recent years, it has been established that a genetic component underlies different forms of the disease. For instance, mitochondrial genome variants have been implicated in the pathogenesis of the PD.

Analysis of the rs13306560 functional variant in the promoter region of the MTHFR gene in sporadic Parkinson´s disease.

Objective: Among susceptibility genes for Sporadic Parkinson´s Disease (SPD), the MTHFR gene has been suggested as candidate. The A allele of the functional variant rs13306560 in its promoter region has been liked to decreased transactivation capacity. Therefore, we sought to determine a possible association of the rs13306560 and SPD.

Low prevalence of most frequent pathogenic variants of six PARK genes in sporadic Parkinson's disease.

Genetic variants that confer susceptibility to Parkinson's disease (PD) show unbalanced distribution among different populations; genetic predisposition to either familial or sporadic forms of PD in Mexican-mestizo population has not been comprehensively studied. The aim of the present study was to analyze genetic variants in six PARK genes in PD patients. In total 381 individuals (173 patients, 208 controls) were genotyped for p.

Serum and cerebrospinal fluid autoantibodies in patients with neuropsychiatric lupus erythematosus. Implications for diagnosis and pathogenesis.

Background: Despite the uncertainty in the diagnosis of neuropsychiatric involvement in systemic lupus erythematosus (SLE), attempts have been made to record the association of certain antibodies in serum with neuropsychiatric (NP) manifestations. We aimed to assess the behaviour and the association of serum and cerebrospinal fluid (CSF) autoantibodies with NP manifestations in SLE patients (NPSLE).

Methodology/principal Findings: Forty-seven SLE patients, hospitalized because of NP manifestations were included.
