Telomeres Length Variations in a Rheumatoid Arthritis Patients Cohort at Early Disease Onset and after Follow-Up.

Background: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic synovial joint inflammation, progressive disability, premature immune aging, and telomere length (TL) shortening.

Objectives: The objective of the study was to study TL changes in patients at early disease onset and after follow-up.

Methods: Relative leukocyte TL (rLTL) was measured by quantitative polymerase chain reaction (qPCR) in 88 at-admission patients (AAP) with < 1 year of symptoms onset, self-compared after follow-up, and a reference group of sex- and age-matched healthy individuals.

A photographic data set of reef and coral communities across Venezuela.

This dataset contains 2850 photographs of the seafloor in coral communities from Venezuela that were taken during 2017 and 2018. We used a hierarchical experimental design with four random factors representing four different spatial scales: (1) region (hundreds of kilometers), (2) localities (tens of kilometers), (2) reef sites (hundreds of meters) and (3) transects (a couple meters) across the Venezuelan coast. At each site, four 30-m transects were deployed parallel to the coastline, and 15 pictures were taken every other meter at each transect, containing an area of at least 80 × 90cm with enough resolution to identify benthic groups.

A Novel, Likely Pathogenic Germline Variant in a Patient With Unilateral Pheochromocytoma.

Context: Inherited MYC-associated factor X () gene pathogenic variants (PVs) increase risk for pheochromocytomas (PCCs) and/or paragangliomas (PGLs) in adults and children. There is little clinical experience with such mutations.

Objective: This report highlights an important approach.

The use of pseudo-multivariate standard error to improve the sampling design of coral monitoring programs.

The characteristics of coral reef sampling and monitoring are highly variable, with numbers of units and sampling effort varying from one study to another. Numerous works have been carried out to determine an appropriate effect size through statistical power; however, these were always from a univariate perspective. In this work, we used the pseudo multivariate dissimilarity-based standard error (MultSE) approach to assess the precision of sampling scleractinian coral assemblages in reefs of Venezuela between 2017 and 2018 when using different combinations of number of transects, quadrats and points.

Catalytically Impaired TYK2 Variants are Protective Against Childhood- and Adult-Onset Systemic Lupus Erythematosus in Mexicans.

Type I interferon (IFN-I) pathway plays a central role in the systemic lupus erythematosus (SLE) pathogenesis. Recent data suggest that SLE is associated with variants in IFN-I genes, such as tyrosine kinase 2 (TYK2), which is crucial in anti-viral immunity. Here, five TYK2 single nucleotide polymorphisms (SNPs) were genotyped in 368 childhood-onset SLE Mexican patients and 516 sex-matched healthy controls.

[Human papillomavirus infection and its correlates with clinically relevant gynecological and obstetric conditions: A cross-sectional study].

Background And Objetive: To analyze the prevalence of human papillomavirus (HPV) infection and the possible epidemiological association with conditions of clinical relevance in women.

Material And Methods: A cross-sectional study from Mexico City was conducted from January 2012 to December 2014. HPV molecular detection was performed on cervical samples.

Lack of concordance and linkage disequilibrium among brothers for androgenetic alopecia and CAG/GGC haplotypes of the androgen receptor gene in Mexican families.

Background: Androgenetic alopecia (AGA) or common baldness is the most prevalent form of hair loss in males. Familial predisposition has been recognized, and heritability estimated in monozygotic twins suggests an important genetic predisposition. Several studies indicate that the numbers of CAG/GGC repeats in exon 1 of the androgen receptor gene (AR) maybe associated with AGA susceptibility.

Long-term follow-up and pregnancy in a patient with neurenteric cyst: case report.

Background: Neurenteric cysts (NC) are rare congenital anomalies. Cysts are secretory with an epithelial lining and features that resemble those of gastrointestinal and/or respiratory mucosa. They originate embryologically and result from an incomplete separation of the neurenteric canal from the foregut.
