[Biomarkers in Chronic Kidney Disease].

Chronic kidney disease (CKD) is an important public health problem. The classification of CKD by KDOQI and KDIGO and routine reports of the estimation of the glomerular filtration rate (eGFR), have resulted in a higher frequency in the diagnosis of CKD. Identification of CKD subjects and high risk of disease progression and cardiovascular disease (CVD) development is important.

[Factors related to residual renal function loss in patients in peritoneal dialysis].

Background: Residual renal function (RRF) contributes to the quality of life of patients on dialysis. The preservation of RRF is associated with higher patient survival in peritoneal dialysis (PD), and is now accepted that RRF and peritoneal clearance are not of equal value in patient survival. The aim of this study is to know the factors related to RRF loss in prevalent patients in continuous ambulatory peritoneal dialysis (CAPD).

Oral supplementation with glycine reduces oxidative stress in patients with metabolic syndrome, improving their systolic blood pressure.

Reactive oxygen species derived from abdominal fat and uncontrolled glucose metabolism are contributing factors to both oxidative stress and the development of metabolic syndrome (MetS). This study was designed to evaluate the effects of daily administration of an oral glycine supplement on antioxidant enzymes and lipid peroxidation in MetS patients. The study included 60 volunteers: 30 individuals that were supplemented with glycine (15 g/day) and 30 that were given a placebo for 3 months.

[Impaired fasting glucose detection in blood donors population].

Objective: to identify subjects with impaired fasting glucose (IFG), from a group of apparently healthy individuals.

Methods: a cross-sectional study was undertaken in 1188 blood donors, with no family history of diabetes (T2D). All these individuals were subjected to a questionnaire, and biochemical tests.

[Dyslipidemia prevalence and its relationship with insulin resistance in a population of apparently healthy subjects].

Objective: Evaluate dyslipidemia prevalence and its association with insulin resistance in a cohort of apparently healthy subjects.

Material And Methods: A cross-sectional study was conducted with 1,179 donors ages 35 to 65 years. The sample population was comprised of 71% men, with an average age of 44 +/- 7.

[Frequency of gastroesophageal reflux disease in elderly patients attending a family medicine clinic].

Objectives: To ascertain the prevalence of gastroesophageal reflux disease (GERD) in elderly people attending to family medicine clinics.

Material And Methods: the study was conducted by using a prospective design in which participants were randomly selected from a family medicine clinic located in Mexico City. The study was run from August to September 2003, and included patients aged sixty years or older, regardless of gender.

Waist perimeter cutoff points and prediction of metabolic syndrome risk. A study in a Mexican population.

Background: Association between metabolic syndrome (MS) risk factors was analyzed to establish optimum waist perimeter (WP) cutoff points for a Latin American cluster.

Methods: There were 1036 clinically healthy Mexican subjects without a history of CVD. Their full medical history and anthropometric and biochemical parameters were analyzed.

[Depressive symptoms as a risk factor for polypharmacy in patients over 60 years of age].

Objective: To determine the association between depressive symptoms not identified by the family physician and polypharmacy in patients over 60 years old.

Methods: A case-control design with non-probabilistic sampling.

Inclusion Criteria: > or = 60 years old both sexes, without disease or with one disease-balanced illness, and with reliable recording in chart by the last 12 month.

[Differences of risk factors for peripheral arterial disease in type 2 diabetes patients in urban and suburban populations].

Objectives: To determine the prevalence of peripheral arterial disease (PAD) in type 2 diabetes patients and to measure the strength of the association of selected risk factors.

Methodology: A cross-sectional study including two hundred and fifty-two type 2 diabetes patients older than 40 years was conducted in three family medicine clinics, one clinic located within the city and two clinics in the suburb. PAD was diagnosed by Doppler pulsed in the patients with an ankle/arm index < 0.

[Professional burnout in family physicians and its association with social demographic and labor factors].

Objective: To determinate the prevalence of burnout in family physicians of the Family Medicine Units in the Estado de México and its association with labor and socio demographics factors.

Material And Methods: A transversal study was made in five Family Medicine Units. 154 physicians of both sex participated in this study.

[Overweight and obesity in health team of a family medicine unit].

Introduction: The overweight and obesity are important public health problems in Mexico and around the world because it has been a progressive growth.

Objectives: To identify the frequency of overweight and obesity in heath workers at a family care unit in the Mexican Institute of Social Security.

Material And Methods: A descriptive, glimpsing and transversal study was done.

[Development and initial validation of an instrument to measure the lifestyles of type 2 diabetes mellitus patients 2].

Objective: To develop and validate a specific instrument to measure lifestyle of type 2 diabetes mellitus (DM2) patients.

Material And Methods: A longitudinal, observational, prospective study was conducted between March 2001 and April 2002 at family medicine healthcare units of the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security (MISS)) in Mexico State's East District. A self-administered instrument (instrument to measure diabetic lifestyles, IMEVID) was designed to measure the lifestyles of diabetic patients.

[Family-physician factors associated with glycemic control of patients with diabetes mellitus].

Introduction: Metabolic control of patients with diabetes is determined by several factors, among others competence level, performance, and attitudes of primary-care physicians.

Objective: On objective was to determinate family physician factors associated with glycemic control in subjects with diabetes in two Family Medicine Units (FMU).

Design: Cross-sectional comparative study.

[Comparison of fasting and 2 hours postprandial blood glucose in the control of patients with type 2 diabetes].

Background: Fasting glycemia is a questionable control test for subjects with diabetes mellitus. 2-h postprandial glycemia is an element that must be considered as complementary in controlling the disease.

Objectives: Compare usefulness of fasting glycemia and 2-h postprandial glycemia as control tests in patients with type 2 diabetes mellitus.
