Mismatch repair system in colorectal cancer. Frequency, cancer phenotype, and follow-up.

Introduction And Aims: A frequent task in the study of colorectal carcinomas (CRC) is to identify tumors harboring deficient DNA mismatch repair systems (dMMR), which are associated with microsatellite instability. Given that there is scant information on those tumors in Mexican patients, our aim was to describe their frequency, clinical and pathologic characteristics, and results, which are necessary for future trials.

Materials And Methods: A consecutive series of CRC patients, treated and followed at a tertiary care center was performed.

Use of antimalarial drugs is associated with a lower risk of preeclampsia in lupus pregnancy: A prospective cohort study.

Introduction: Several factors have been associated with the development of preeclampsia in women with systemic lupus erythematosus (SLE).

Objective: To identify risk factors associated with preeclampsia in patients with SLE and its impact on fetal outcomes.

Patients And Methods: We studied a prospective cohort of pregnancies in women with SLE from January 2009 to December 2018.

Detection of autoantibodies to DSF70/LEDGFp75 in Mexican Hispanics using multiple complementary assay platforms.

Purpose: Antinuclear autoantibodies (ANA) targeting the dense fine speckled antigen DFS70, also known as lens epithelium-derived growth factor p75 (LEDGF/p75), are attracting attention due to their low frequency in systemic rheumatic diseases but increased frequency in clinical laboratory referrals and healthy individuals (HI). These ANA specifically recognize the stress protein DFS70/LEDGFp75, implicated in cancer, HIV-AIDS, and inflammation. While their frequency has been investigated in various ethnic populations, there is little information on their frequency among Hispanics/Latinos.

Active haematological manifestations of systemic lupus erythematosus lupus are associated with a high rate of in-hospital mortality.

The aim of this study was to estimate the impact of the haematological manifestations of systemic lupus erythematosus (SLE) on mortality in hospitalized patients. For that purpose a case-control study of hospitalized patients in a medical referral centre from January 2009 to December 2014 was performed. For analysis, patients hospitalized for any haematological activity of SLE ( n = 103) were compared with patients hospitalized for other manifestations of SLE activity or complications of treatment ( n = 206).

Clinical practice guidelines for the management of pregnancy in women with autoimmune rheumatic diseases of the Mexican College of Rheumatology. Part II.

Background: Pregnancy in women with autoimmune rheumatic diseases is associated with several maternal and fetal complications. The development of clinical practice guidelines with the best available scientific evidence may help standardize the care of these patients.

Objectives: To provide recommendations regarding prenatal care, treatment, and a more effective monitoring of pregnancy in women with lupus erythematosus, rheumatoid arthritis (RA) and antiphospholipid syndrome (APS).
