Prolactinomas are the most common functional pituitary tumors, accounting for 40% of all pituitary adenomas. Medical treatment with dopamine agonists (DA), mainly cabergoline, is considered the primary therapy for these patients. Prolactin normalization is achieved in 80-90% of prolactinomas treated with cabergoline. Patients resistant to the standard dose can escalate the dose of cabergoline up to the maximum tolerated dose. The expression of dopamine (D2) receptors and dopamine affinity is decreased in aggressive and resistant prolactinomas...

AIM: Evaluate insulin resistance (IR) as a mediator of the effect of body fat distribution on liver fat infiltration and stiffness (LSt) in young adults using structural equation modeling (SEM). METHODS: We invited 500 first year students from two universities and evaluated their family history to determine the risk for cardiometabolic disease. Of these, 174 students (age 19 ± 1 years) were assessed for total body fat percentage (BF%), LSt, fat infiltration (Coefficient attenuated parameter CAP), and serum biochemical analysis...

Pegvisomant, the first and currently only clinically available growth hormone receptor antagonist, is an effective therapeutic option for the medical treatment of acromegaly, a rare disorder characterized by excessive growth hormone secretion. With now over 20 years of real world experience, its safety and efficacy is well-established. However, several aspects of its clinical use are still controversially discussed. The high cost of pegvisomant has limited its use in several countries, and recent studies have reported a lower efficacy than the initial clinical trials...

Transsphenoidal resection remains the standard treatment for most pituitary adenomas. However, the ideal surgical approach to safely access these lesions, either microsurgical or endoscopic, continues to be debated. Since the introduction of endoscopic transsphenoidal surgery, centers around the world have increasingly adopted this technique, experiencing a shift away from the conventional microsurgical approach. Large series reporting the efficacy and safety of endoscopic surgery have fueled a growing interest in comparing clinical outcomes between both approaches...

BACKGROUND: Aging and multimorbidity (MM) are not enough to explain patient heterogeneity and outcomes. The objective of this study was to estimate the effect of multimorbidity patterns and indicators of socioeconomic, behavioral, and functional dimensions on the risk of death in a cohort of people ≥50 years old. METHODS: We analyzed a cohort of 7,342 persons ≥50 years old from the Mexican Health and Aging Study (MHAS), stratified by age groups (50-64, 65-84, ≥85 years old)...

BACKGROUND: COVID-19 is associated with systemic inflammation. This inflammatory response is further deregulated by oncological treatments increasing mortality in this population. However, there is conflicting information regarding the clinical factors that increase mortality in patients with severe COVID-19. OBJECTIVE: The aim of this study was to identify prognostic factors associated with mortality during severe COVID-19 in patients with active cancer. In addition, the correlation between oncologic codes and mortality related to severe COVID-19 was evaluated...

BACKGROUND: Bartter's syndrome (BS) is a group of salt-wasting tubulopathies characterized by hypokalemia, metabolic alkalosis, hypercalciuria, secondary hyperaldosteronism, and low or normal blood pressure. Loss-of-function variants in genes encoding for five proteins expressed in the thick ascending limb of Henle in the nephron, produced different genetic types of BS. AIM: Clinical and genetic analysis of families with Antenatal Bartter syndrome (ABS) and with Classic Bartter syndrome (CBS)...

BACKGROUND: Besides its main role in the control of blood cholesterol, PCSK9 has a role in the regulation of neuronal development and apoptosis. We suggest, for the first time, the possible involvement of PCSK9 in autism. METHOD: In this case-control study, Sanger sequencing was used to analyze sequence variations in the PCSK9 gene exons and their flanking intronic sequences. ELISA assay was used to determine the plasma concentration of PCSK9. The methylation percentage of the PCSK9 gene promoter was assessed by methylation-specific PCR (MSP)...

BACKGROUND AND AIM: While preliminary evidence points to pro-tumorigenic roles for the Musashi (MSI) RNA-binding proteins Musashi-1 (MSI1) and Musashi-2 (MSI2) in some breast cancer subtypes, no data exist for inflammatory breast cancer (IBC). METHODS: MSI gene expression was quantified in IBC SUM149PT cells. We then used small interfering RNA-based MSI1 and MSI2 double knockdown (DKD) to understand gene expression and functional changes upon MSI depletion. We characterized cancer stem cell characteristics, cell apoptosis and cell cycle progression via flow cytometry, mammospheres via spheroid assays, migration and proliferation via digital holographic microscopy, and cell viability using BrdU assays...

INTRODUCTION: Despite the inherent heterogeneity of the information derived from national registries, they are a useful tool to investigate the epidemiological, clinical, biochemical and treatment outcome characteristics of low prevalence conditions such as acromegaly. Although the information provided by single-center experiences is more homogeneous, these studies usually comprise a limited number of patients and thus, frequently lack statistical power. AREAS COVERED: Registry-based Information regarding the epidemiology, clinical presentation, biochemical and imaging diagnosis, as well as therapeutic outcome and mortality in acromegaly is critically analyzed...

BACKGROUND: Dysregulation of MSCs differentiation is associated with many pathophysiological processes. Genetically modified MSCs transplantation helps restore bone loss efficiently. METHODS: BMSCs-specific QKI overexpressing and knockdown mice were built to explore QKI's role in bone formation and fat accumulation. Primary BMSCs with QKI overexpression and knockout were subjected to osteogenic and adipogenic differentiation. ALP staining and oil red O staining were performed to evaluate the differences between the groups...

BACKGROUND AND OBJECTIVES: Overexpression of the EZH2 gene silences several genes involved in DNA repair, cell-cell adhesion, and tumor suppressor genes, resulting in the development of several types of cancers. In the present study, a genetic polymorphism analysis was performed by selecting three SNPs (rs.2302427C>G, rs.3757441C>T, and rs.6950683T>C) of the EZH2 gene based on our previous in silico studies. METHODS: A total of 250 breast cancer patients and 250 healthy individuals were recruited for the study...

BACKGROUND: Clinically Isolated Syndrome (CIS) is the first clinical episode suggestive of Clinical Definite Multiple Sclerosis (CDMS). There are no reports on possible predictors of conversion to CDMS in Mexican mestizo patients. AIM OF THE STUDY: To investigate immunological markers, clinical and paraclinical findings, and the presence of herpesvirus DNA to predict the transition from CIS to CDMS in Mexican patients. METHODS: A single-center prospective cohort study was conducted with newly diagnosed patients with CIS in Mexico between 2006 and 2010...

BACKGROUND AND AIM: Obesity is a potentially modifiable factor for reducing readmissions, with heterogeneity that varies according to the metabolic status. Our objective was to examine the independent or mutual relationship between obesity and metabolic abnormalities and diabetic kidney disease (DKD)-related hospitalizations. METHODS: 493,570 subjects with DKD were enrolled in the 2018 Nationwide Readmission Database (NRD, United States). The at-risk population was reclassified into refined obesity subtypes based on the body mass index (BMI) classification of metabolic abnormalities (hypertension and/or dyslipidemia) to investigate the 180 d readmission risk and hospitalization costs related to DKD...
