Long-Term Effectiveness of Polymerized-Type I Collagen Intra-Articular Injections in Patients with Symptomatic Knee Osteoarthritis: Clinical and Radiographic Evaluation in a Cohort Study.

Objective: Polymerized-type I collagen (polymerized-collagen) is a downregulator of inflammation and a tissue regenerator.

Association of anthropometric indicators to evaluate nutritional status and cardiometabolic risk in Mexican teenagers.

Introduction: anthropometric indicators (AIs) such as waist circumference (WC), body mass index (BMI), waist/hip index (WHpI), waist/height index (WHtI) and body fat percentage (BFP) are useful tools for the diagnosis of nutritional status (NS) in adolescents. Each of these parameters has advantages and disadvantages. The purpose of the present study was to analyze the association of these AIs (WC, BMI, WHpI, WHtI, and BFP) to evaluate nutritional status and estimate the cardiometabolic risk (CMR) in Mexican adolescents.

[Family medicine in Mexico: Present and future].

Analyzing the challenges and the future scenario of Family Medicine is a priority to address challenges such as the reduction of benefits granted by social security; to adapt their practice to the changing health profile; and to curb demand for specialized services and contain the high costs of care in the second and third level. The program is aimed at three professional roles: medical care, research, and education. It is imperative review these in the light of changing demographic conditions, the type of health needs arising from new social determinants, the public expectations for greater participation in their care, and the evolution of the health system itself with the advancement of technology and a variety of organizational options with frequently limited resources.

Applying the Fuzzy Delphi Method for determining socio-ecological factors that influence adherence to mammography screening in rural areas of Mexico.

In Mexico, regular participation in mammography screening is low, despite higher survival rates. The objective of our research is to highlight healthcare procedures to be optimized and target areas to encourage investment and to raise awareness about the benefits of early diagnosis. Those socio-ecological factors (community, interpersonal and individual) were collected through a review of literature and based on the spatial interaction model of mammography use developed by Mobley et al.

[Behavior of hypertensive renal diseases in Mexico between 1998-2009. A growing problem].

Introduction: High blood pressure (HBP) is a risk factor for chronic diseases. Worldwide, 20-25% of adults have hypertension, with 70% of them living in developing countries. Hypertensive renal disease (HRD) is a complication of insufficiently controlled hypertension.

Social epidemiology of a large outbreak of chickenpox in the Colombian sugar cane producer region: a set theory-based analysis.

There are few social epidemiologic studies on chickenpox outbreaks, although previous findings suggested the important role of social determinants. This study describes the context of a large outbreak of chickenpox in the Cauca Valley region, Colombia (2003 to 2007), with an emphasis on macro-determinants. We explored the temporal trends in chickenpox incidence in 42 municipalities to identify the places with higher occurrences.

[Case crossover studies: a conceptual and methodological approach].

Case crossover studies are considered as a variant of case control studies, and they have been included in the scientific literature since approximately eighteen years ago. They have also been used in epidemiological research on acute or intermittent exposures that may lead to a number of events including heart attack or cardiac arrest, injuries, asthma, etc. Application of this particular study design requires defining concepts such as: triggers, induction time, case period and control period.
