Effect of Tibolone on Bone Mineral Density in Postmenopausal Women: Systematic Review and Meta-Analysis.

Biology (Basel)

March 2021

Research Unit on Gerontology, Facultad de Estudios Superiores Zaragoza, Universidad Nacional Autónoma de México, Mexico City 09230, Mexico.

Low bone mineral density (BMD) on postmenopausal women causes bone fragility and fracture risk. Tibolone seems to prevent bone loss. Therefore, this systematic review with meta-analysis synthesizes the tibolone effect on BMD percent change in lumbar spine (LS), femoral neck (FN), and total hip (TH) in postmenopausal women.

January 2022

Medical Research Unit on Nephrological Diseases, Specialties Hospital, 21st Century National Medical Center, Mexican Institute of Social Security (IMSS) (Unidad de Investigación Médica en Enfermedades Nefrológicas, Hospital de Especialidades Centro Médico Nacional Siglo XXI, IMSS), Mexico City, Mexico,

Background/aims: Vascular access (VA) is the highest risk factor for blood infections, hospitalization, and mortality of patients undergoing hemodialysis (HD). The risk of mortality while using a catheter is greater than that while using grafts. The objective of this article is to know the survival rate in relation to the type of VA.

Reference values for bone mineral density in healthy Mexican children and adolescents.

Bone

January 2021

Clinical Epidemiology Research Unit, Hospital Infantil de México Federico Gómez, Mexico; Universidad Nacional Autonoma de México, Mexico City, Mexico. Electronic address:

Introduction: Clinical assessment of bone health by Dual-Energy X-ray Absorptiometry (DXA) in the paediatric population requires robust reference values. The International Society for Clinical Densitometry (ISCD) recommends that country/regional reference values ideally should be used to improve precision in bone health assessment.

Objective: The aim of this study was to provide reference values for relevant bone health variables for healthy Mexican children and adolescents aged 5 to 18 years.

Configuration of bioelectrical impedance measurements affects results for phase angle.

Med Eng Phys

October 2020

Institut für Humanernährung und Lebensmittelkunde, Christian-Albrechts-Universität Kiel, Düsternbrooker Weg 17, 24105 Kiel, Germany.

Article Synopsis
  • - The study examines how phase angle (PhA), an indicator of malnutrition from bioelectrical impedance analysis, varies by measurement configuration such as body position (supine vs. standing), type of electrodes, and side of the body.
  • - Results show that PhA is consistently higher in supine position compared to standing, with significant variation based on electrode type and body side, particularly in both children and adults.
  • - The findings emphasize the importance of standardizing measurement conditions, as variations in posture and electrode placement can significantly impact PhA results when comparing across different devices or studies.

Overweight (OW) and obesity (OB) during childhood/adolescence are major public health problems in Mexico. Several obesogenic lifestyle (OL) risk factors have been identified, but the burden and consequences of them in Mexican children/adolescents remain unclear. The objective of this study was to estimate the prevalence of OL components and describe their relationships with adiposity, and OW/OB.

Introduction: Malnutrition is common in haemodialysis patients and closely related to morbidity and mortality. We evaluated the effect of twelve weeks of supplementation with resveratrol and curcumin on recovery of bone and muscle mass and protein oxidation, lipid peroxidation on patients with chronic kidney disease and iron overload undergoing hemodialysis, we performed a randomized, double-blind, placebo-controlled trial.

Methods: We included a total of 40 patients, were randomly assigned to two groups, 20 to the group with antioxidant supplementation (Resveratrol + Curcumin) (Group A), treated with a daily oral dose of 500 mg of Resveratrol and 500 mg of Curcumin, and 20 to the control group treated with placebo (Group B).

Purpose: We analyzed the epidemiologic characteristics of different types of non-Hodgkin Lymphoma (NHL), excluding Burkitt Lymphoma, in 2 Mexican regions with different socioeconomic status.

Materials And Methods: In this surveillance study, we analyzed the incidence rates (cases per million children/year) of different types of NHL according to the ICCC3, registered in 1996-2015, from 2 different socioeconomic regions in Mexico: central and southern, with higher and lower status, respectively.

Results: The principal NHL subgroups were precursor (IIb1), mature B cell (IIb2), mature T/NK cell, and no other specification (NOS; 42.

Previous studies in the Mexican adult population have suggested a relationship between low levels of serum concentrations of serum vitamin D with impaired glucose tolerance, metabolic syndrome, and diabetes, regardless of the presence of obesity. The aim of this study is to investigate the relationship between serum vitamin D levels and the factors linked to insulin resistance. A total of 533 children and adolescents from the "Reference Values of Body Composition in the Pediatric Population of Mexico City" study are assessed.

Background: Understanding early-life complementary feeding dietary patterns and their determining factors could lead to better ways of improving nutrition in early childhood. The purpose of this review was to evaluate evidence of the association between sociodemographic factors and dietary patterns (DPs) in children under 24 months.

Methods: Medline (PubMed), Cochrane Central, NICE guidelines, and Trip database were searched for observational studies that evaluated sociodemographic factors and their associations with DP.

Aims: To understand the epidemiology, progression, and predictive factors of urinary incontinence (UI) in community-dwelling Mexican adults aged ≥ 50 by sex and UI subtypes (stress, urge, and mixed).

Methods: We analyzed longitudinal UI data in community-dwelling adults aged ≥ 50 (7783 women and 5843 men) for the 2012 to 2015 period of the Mexican Health and Aging Study. We estimated mixed, stress, and urgency incontinence prevalence (2012); 2-year cumulative incidence and remissions (2015); and progression (2012-2015).

The aim of this systematic review was to assess the evidence on the relation between dietary patterns, bone mineral density (BMD), and risk of fracture in different age groups. Medline and Embase were searched for articles that identified dietary patterns and related these to BMD or risk of fracture through May 2018. Multivariable adjusted odds ratios (ORs) and 95% confidence intervals (95%CI) comparing the lowest and highest categories of dietary pattern were combined by using a random effects meta-analysis.
