RESUMO
BACKGROUND: Aim to this study is to investigate the association of Dietary Counseling, Meal Patterns, and Diet Quality (DietQ) in Patients with Type 2 Diabetes Mellitus (T2DM) with/without chronic kidney disease (CKD) in primary healthcare. METHODS: Cross-sectional study acquired data on dietary counseling and meal patterns by direct interview with a food-frequency questionnaire and one 24-h food-recall. The Healthy Eating Index (HEI) was used to classify DietQ ["good" DietQ (GDietQ, score ≥ 80) and "poor" DietQ (PDietQ, score < 80)]. PARTICIPANTS/SETTING: This study included 705 patients with T2DM: 306 with normal kidney function; 236 with early nephropathy, and 163 with overt nephropathy (ON). STATISTICAL ANALYSES PERFORMED: Multivariate linear-regression models for predicting HEI and χ2 tests for qualitative variables and one-way ANOVA for quantitative variables were employed. Mann-Whitney U and independent Student t were performed for comparisons between GDietQ and PDietQ. RESULTS: Only 18 % of the population was classified as GDietQ. Patients with ON and PDietQ vs. with GDietQ received significantly less dietary counseling from any health professional in general (45 % vs 72 %, respectively), or from any nutrition professional (36 % vs. 61 %, respectively). A better HEI was significantly predicted (F = 42.01; p = 0.0001) by lower HbA1C (ß -0.53, p = 0.0007) and better diet diversity (ß 8.09, p = 0.0001). CONCLUSIONS: Patients with more advanced stages of CKD had less nutritional counseling and worse dietary patterns, as well as more frequent PDietQ. Our findings reinforce the need for dietitians and nutritionists in primary healthcare to provide timely nutritional counseling.

Background: In dialysis patients, on the one hand unwillingness to change negative lifestyle patterns is associated with worse nutritional status and unhealthy lifestyle, whereas on the other, pica may be highly prevalent. However, it is not known whether pica is associated with unwillingness to change negative lifestyle behaviors, as well as with consumption of different types of foods. This study aimed to investigate this issue. Methods: This is a cross-sectional study in dialysis patients. Lifestyle was assessed using the self-administered Instrument to Measure Lifestyle Questionnaire (IMEVID). Pica diagnosis was established according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. A food frequency questionnaire was performed and self-reported willingness to change was determined by a trans-theoretical model staging inventory. Results: Compared with patients without pica, those with pica (particularly hard pica) had lower willingness to change unhealthy behavior in the case of diet (22% vs. 46% in precontemplation/contemplation stages, respectively) and exercise (43% vs. 62% in precontemplation/contemplation stages, respectively). Patients with hard pica had significantly (p < 0.05) lower scores in almost all dimensions of the lifestyle questionnaire than those in the no pica group: diet (23.9 vs. 26.8, respectively), physical activity (5.5 vs. 7, respectively), knowledge of disease (5.7 vs. 6.4, respectively), emotion management (6.6 vs. 8, respectively) and adherence to treatment (13.4 vs. 14.7, respectively), but not in the consumption of tobacco and alcohol. Compared to patients with no pica, those with hard pica ate vegetables and fruits less frequently, and dairy products, fried foods and soda more frequently. Conclusions: Pica was more frequently observed in patients with lower willingness to change negative habits of diet and exercise, in those who had more unhealthy behaviors in diet, exercise and emotion management dimensions and adherence to treatment, as well as in those who ate less frequently healthful foods and more frequently unhealthy foods.
RESUMO
Gut microbiota disturbances may influence cognitive function, increasing uremic toxins and inflammation in dialysis patients; therefore, we aimed to evaluate the association of the gut microbiota profile with cognitive impairment (CI) in patients on automated peritoneal dialysis (APD). In a cross-sectional study, cognitive function was evaluated using the Montreal Cognitive Assessment in 39 APD patients and classified as normal cognitive function and CI. The gut microbiota was analyzed using the 16S rRNA gene sequencing approach. All patients had clinical, biochemical and urea clearance evaluations. Eighty-two percent of patients were men, with a mean age of 47 ± 24 years and 11 (7-48) months on PD therapy; 64% had mild CI. Patients with CI were older (53 ± 16 vs. 38 ± 14, p = 0.006) and had a higher frequency of diabetes mellitus (56% vs. 21%, p = 0.04) and constipation (7% vs. 48%, p = 0.04) and lower creatinine concentrations (11.3 ± 3.7 vs. 14.9 ± 5.4, p = 0.02) compared to normal cognitive function patients. Patients with CI showed a preponderance of S24_7, Rikenellaceae, Odoribacteraceae, Odoribacter and Anaerotruncus, while patients without CI had a greater abundance of Dorea, Ruminococcus, Sutterella and Fusobacteria (LDA score (Log10) > 2.5; p < 0.05). After glucose and age adjustment, Odoribacter was still associated with CI. In conclusion, patients with CI had a different gut microbiota characterized by the higher abundance of indole-producing and mucin-fermenting bacteria compared to normal cognitive function patients.

OBJECTIVE: Health-care workers are in high risk for COVID-19 and may experience associated mental health disturbances. Although physical activity (PA) has positive effects on mental disturbances, it has not been fully investigated in health-team during COVID-19 pandemic. Therefore, we analyzed depression, anxiety and stress in health-care workers, and their relationship with PA before and during a COVID-19 peak. METHODS: Retrospective cohort study. PA (IPAQ short-form) evaluated and associated with depression, anxiety and stress (DAAS-21) at the beginning of COVID-19 first wave in Mexico (April 2020) in 1146 workers of a tertiary-care hospital, and in a subsequent occasion at the first wave peak (July-August/2020) in 311 workers (from the first ones). Data collected from routine surveillance. RESULTS: Depression increased 9%, anxiety 15%, and stress 10% at the pandemic peak. Subjects with higher frequency of baseline moderate PA showed lower severity of depression, anxiety and stress at the peak (p < 0.05). At the pandemic peak, female sex (OR = 2.42, 95%CI 1.14-5.13), diabetes (OR = 21.9, 95%CI 2.09-221) and baseline depression (OR = 8.86, 95%CI 4.30-18.2) predicted depression; baseline anxiety (OR = 5.52, 95%CI 3.01-10.1), working in COVID-19 area (OR = 4.14, 95%CI 1.99-8.64), and baseline moderate PA (OR = 0.35, 95%CI 0.16-0.73) predicted anxiety; and baseline stress (OR = 8.64, 95%CI 4.11-18.2), and moderate PA (OR = 0.35, 95%CI 0.15-0.82) predicted stress. CONCLUSION: Depression, stress, and particularly anxiety, increased in health-care workers from the beginning to the COVID-19 pandemic peak, and were predicted by the presence of the corresponding baseline mental alterations, and in the case of anxiety and stress, by the lower frequency of moderate PA.
RESUMO
Protein-energy wasting (PEW) is common in patients with chronic kidney disease (CKD) and is associated with increased morbidity and mortality, and lower quality of life. It is a complex syndrome, in which inflammation and retention of uremic toxins are two main factors. Causes of inflammation and uremic toxin retention in CKD are multiple; however, gut dysbiosis plays an important role, serving as a link between those entities and PEW. Besides, there are several pathways by which microbiota may influence PEW, e.g., through effects on appetite mediated by microbiota-derived proteins and hormonal changes, or by impacting skeletal muscle via a gut-muscle axis. Hence, microbiota disturbances may influence PEW independently of its relationship with local and systemic inflammation. A better understanding of the complex interrelationships between microbiota and the host may help to explain how changes in the gut affect distant organs and systems of the body and could potentially lead to the development of new strategies targeting the microbiota to improve nutrition and clinical outcomes in CKD patients. In this review, we describe possible interactions of gut microbiota with nutrient metabolism, energy balance, hunger/satiety signals and muscle depletion, all of which are strongly related to PEW in CKD patients.

Increased muscle protein catabolism leading to muscle wasting is a prominent feature of the syndrome of protein-energy wasting (PEW) in patients with chronic kidney disease (CKD). PEW and muscle wasting are induced by factors such as inflammation, oxidative stress and metabolic acidosis that activate the ubiquitin-proteasome system, the main regulatory mechanism of skeletal muscle degradation. Whether deficiency of nuclear factor erythroid 2-related factor 2 (NRF2), which regulates expression of antioxidant proteins protecting against oxidative damage triggered by inflammation, may exacerbate PEW has yet to be examined in aging patients with CKD. This review focuses on the hypothesis that NRF2 is involved in the maintenance of muscle mass and explores whether sustained activation of NRF2 by non-pharmacological interventions using nutraceutical activators to improve redox homeostasis could be a plausible strategy to prevent skeletal muscle disorders, including muscle wasting, sarcopenia and frailty associated with PEW in aging CKD patients.

To evaluate individual and combined effect of captopril and telmisartan on systemic inflammation markers of hemodialysis (HD) patients. Randomized, double-blinded, controlled clinical trial. Patients on HD at least 2 months, with arteriovenous fistula, were randomly allocated to groups: (1) captopril/placebo (N 13); (2) telmisartan/placebo (N 13); (3) captopril + telmisartan (N 12); or (4) placebo/placebo (N 12). During 3 months, patients received oral drugs as follows: captopril 50 mg/day, telmisartan 80 mg/day or placebo. Patients excluded if they had conditions or were on drugs potentially influencing on inflammation. Clinical and biochemical evaluations were performed monthly. Serum tumor necrosis factor alpha (TNFα), interleukin 6 (IL-6), and C-reactive protein (CRP) were measured at 0, 1 and 3 months. Baseline, demographic, clinical and biochemical variables were comparable between groups. Baseline versus final inflammatory markers were: captopril/placebo TNFα, 2.47 (0.1-4.5) versus 1.73 (0.3-3.8) pg/ml; IL-6, 17.03 (7.2-23) versus 7.90 (0.7-19) pg/ml; CRP, 4.21 (1.6-18) versus 5.9 (3.0-28) mg/l; telmisartan/placebo TNFα, 3.03 (2.3-4.6) versus 1.70 (1.2-2.0) pg/ml; IL-6, 14.10 (5.5-23) versus 9.85 (6.2-13) pg/ml; CRP, 5.74 (2.1-13) versus 10.60 (1.5-27) mg/l; captopril + telmisartan TNFα, 1.43 (0.7-5.4) versus 0.40 (0.1-2.1) pg/ml; IL-6, 10.05 (4.9-23) versus 4.00 (0.7-7.7) pg/ml (p < 0.05); CRP, 3.26 (0.7-12) versus 2.83 (0.6-6.5) mg/l; placebo/placebo TNFα, 3.13 (1.6-5.6) versus 1.64 (1.6-2.3) pg/ml; IL-6, 8.12 (5.4-16) versus 7.60 (2.4-15) pg/ml; CRP, 5.23 (1.9-16) versus 3.13 (1.5-18) mg/l. Monotherapy with captopril or telmisartan display a trend, but their combined treatment significantly decreased serum levels of IL-6. No remarkable changes on TNFα and CRP were observed.

Protein-energy wasting (PEW) and poor health-related quality of life (HRQoL) are independently associated with morbi-mortality in continuous ambulatory peritoneal dialysis (CAPD). PEW may reduce HRQoL; however, we hypothesized HRQoL is affected differentially by PEW degrees or by individual criteria of nutritional status. AIM: To evaluate HRQoL according to PEW severity and nutritional status indicators in CAPD. This is a cross-sectional study in 151 patients. Subjective global assessment (SGA) was employed, and nutritional status classified as normal, mild-moderate PEW, and severe PEW. HRQoL was evaluated using Kidney Disease Quality of Life Short Form™, including physical (PCS), mental (MCS) and kidney disease (KDCS) components, and their subscales. Dietary intake, anthropometric and biochemical variables were measured. Forty-six percent of patients were well-nourished, 44% had mild-moderate PEW, and 10% severe PEW. Compared with well-nourished patients, those with mild-moderate (p=0.06) and severe (p=0.005) PEW had lower HRQoL score [68 (52-75), 55 (45-72), 46 (43-58), respectively]. PCS, MCS, and KDCS and their subscales had lower values as PEW was more severe. Patients with obesity and hypoalbuminemia had significantly lower HRQoL overall and component scores than their counterparts. Dietary intake was not associated with quality of life. In multivariate analysis obesity, PEW (by SGA), hypoalbuminemia, and low educational level predicted poor HRQoL (χ2 58.2, p<0.0001). As conclusion, PEW severity was related with worse HRQoL, either as overall score or in every component or subscale in CAPD patients. Poor HRQoL was predicted independently by PEW severity and obesity; additional predictors were hypoalbuminemia and low education.

BACKGROUND: Malnutrition and inflammation are highly prevalent and associated with poor outcomes in continuous ambulatory peritoneal dialysis (CAPD). Nutritional supplements are commonly used; however, presence of systemic inflammation could limit their effect. AIM: To evaluate the impact of systemic inflammation on nutritional status of CAPD patients receiving an oral protein supplement. METHODS: Prospective observational study; 34 malnourished patients (subjective global assessment; SGA) received both nutritional counseling and oral egg albumin-based protein supplement. During 6-month of follow-up, patients had monthly clinical, and quarterly biochemical and inflammation [interleukin 6 and high sensitivity C-reactive protein (hsCRP)] evaluations. According to baseline hsCRP, patients were classified in two groups: Inflammation (>3 mg/L) and No-inflammation (≤3 mg/L). RESULTS: Comparing baseline vs final, macronutrient intake and SGA increased in both groups, however, improvement of SGA was more marked in the No-inflammation group at the end of the study: 70% improved, 25% no change and 5% worsened (p = 0.001); whereas in the Inflammation group results were: 50% improved, 36% no change and 14% worsened (p = 0.03). Additionally, at final evaluation, serum albumin tended to increase more in the No-inflammation (3.0 ± 0.9 vs 3.4 ± 1.1 g/dL, p = 0.08) than in Inflammation group (2.8 ± 0.6 vs 3.0 ± 0.9 g/dL, p = 0.66), and body mass index significantly increased in No-inflammation group (20.3 ± 3.0 vs 21.6 ± 3.3 kg/m2, p < 0.001) but not in Inflammation group (21.9 ± 3.0 vs 22.5 ± 3.3 kg/m2, p = 0.09). CONCLUSIONS: The presence of systemic inflammation in malnourished CAPD patients seemed to limit the trend for improvement on nutritional status observed with counseling and oral egg albumin-based protein supplement in patients without inflammation.

BACKGROUND & AIMS: Evidence suggests that multiple-behavior interventions (with a specialist) have a greater impact on public health than single-behavior interventions, particularly in a chronic patient. However, there is little understanding of some very basic principles concerning multiple health behavior change, especially in situations such as kidney transplantation, which requires a great willingness to change negative lifestyle behaviors to achieve intermediate and long-term success. We compared healthy lifestyles and nutritional status according to the willingness to change dietary and exercise behavior in dialysis patients from a living donor kidney transplant program. METHODS: 400 dialysis patients had a dietetic, anthropometric, protein-energy wasting [subjective global assessment (SGA)] and biochemical evaluation. Lifestyle was evaluated with an adapted instrument to measure lifestyle in chronic disease. Willingness to change behaviors was evaluated by the trans-theoretical model; 2 groups were formed: willingness to change dietary and exercise behaviors and unwillingness to change. RESULTS: Willingness to change dietary behavior was 50% and exercise 25%. Patients with willingness to change dietary and exercise behaviors had better healthy lifestyle scores, and higher frequency of healthy food consumption. Healthy lifestyle score (R2 = 0.37, p < 0.0001) was predicted by older age, higher educational degree, shorter time on dialysis, and the highest willingness to change dietary and exercise behaviors. CONCLUSIONS: Willingness to change dietary and exercise behaviors was associated with healthy lifestyle, as well as with higher frequency of healthy food consumption and with lower frequency of unhealthy food consumption.

Background: There are many clinical practice guidelines (CPGs) in Nephrology; however, there is no evidence that their availability has improved the clinical competence of physicians or the outcome of patients with chronic kidney disease (CKD). This study was aimed to evaluate the effect of implementation of CPGs for early CKD on family physicians (FP) clinical competence and subsequently on kidney function preservation of type 2 diabetes mellitus (DM2) patients at a primary healthcare setting. Methods: A prospective educative intervention (40-h) based on CPGs for Prevention, Diagnosis and Treatment of Early CKD was applied to FP; a questionnaire to evaluate clinical competence was applied at the beginning and end of the educative intervention (0 and 2 months), and 12 months afterwards. DM2 patients with CKD were evaluated during 1-year of follow-up with estimated glomerular filtration rate (eGFR) and albuminuria. Results: After educative intervention, there was a significant increase in FP clinical competence compared to baseline; although it was reduced after 1 year, it remained higher compared to baseline. One-hundred thirteen patients with early nephropathy (58 stage 1, 55 stage 2) and 28 with overt nephropathy (23 stage 3, 5 stage 4) were studied. At final evaluation, both groups maintained eGFR [(mean change) early 0.20 ± 19 pNS; overt 0.51 ± 13 mL/min pNS], whereas albuminuria/creatinuria (early -67 ± 155 p < 0.0001; overt -301 ± 596 mg/g p < 0.0001), systolic blood pressure (early -10 ± 18 p < 0.05; overt -8 ± 20 mmHg p < 0.05), and total cholesterol (early -11 ± 31 p < 0.05; overt -17 ± 38 mg/dL p < 0.05) decreased. Diastolic blood pressure, waist circumference and LDL-cholesterol were also controlled in early nephropathy patients. Conclusions: CPGs for Prevention, Diagnosis and Treatment of CKD, by means of an educative intervention increases FP clinical competence and improves renal function in DM2 patients with CKD.
RESUMO
BACKGROUND & AIMS: Mexico has one of the highest mortality rates by COVID-19 worldwide. This may be partially explained by the high prevalence of overweight/obesity found in general population; however, there is limited information in this regard. Furthermore, acute kidney injury (AKI) and need for renal replacement therapy (RRT) associated to obesity in patients with COVID-19 are still topics of discussion. AIM: To explore the association of obesity, particularly morbid obesity, with mortality and kidney outcomes in a Mexican population of hospitalized patients with COVID-19. METHODS: Retrospective cohort study of 773 patients with COVID-19 hospitalized in a tertiary-care teaching hospital in the Mexican state of Jalisco. Baseline body mass index was classified as: normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), obesity (30-39.9 kg/m2), and morbid obesity (≥40 kg/m2). AKI was diagnosed according to KDIGO clinical practice guidelines. RESULTS: At baseline, 35% of patients had overweight, 39% obesity and 8% morbid obesity. Patients with obesity were younger, more frequently women and with hypertension than normal weight and overweight patients. Frequency of complications in the univariate analysis were not significantly associated to obesity, however in the multivariate analysis (after adjusting for baseline clinical and biochemical differences), morbid obesity was significantly associated to an increased risk of AKI [OR = 2.70 (1.01-7.26), p = 0.05], RRT [OR = 14.4 (1.46-42), p = 0.02], and mortality [OR = 3.54 (1.46-8.55), p = 0.005]. CONCLUSIONS: Almost half of the sample had obesity and morbid obesity. Morbid obesity was significantly associated to an increased risk of AKI, RRT and mortality in hospitalized patients with COVID-19.

OBJECTIVE: To describe mortality of in-hospital patients with COVID-19 and compare risk factors between survivors and non-survivors. DESIGN: Prospective cohort of adult inpatients. SETTING: Tertiary healthcare teaching hospital in Guadalajara, Mexico. PARTICIPANTS: All patients with confirmed COVID-19 hospitalised from 25 March to 7 September 2020 were included. End of study: 7 November 2020. PRIMARY OUTCOME MEASURES: Patient survival analysed by the Kaplan-Meier method and comparison of factors by the log-rank test. Mortality risk factors analysed by multivariate Cox's proportional-hazard model. RESULTS: One thousand ten patients included: 386 (38%) died, 618 (61%) alive at discharge and six (0.6%) remained hospitalised. There was predominance of men (63%) and high frequency of overweight-obesity (71%); hypertension (54%); diabetes (40%); and lung (9%), cardiovascular (8%) and kidney diseases (11%); all of them significantly more frequent in non-survivors. Overweight-obesity was not different between groups, but severity of disease (Manchester Triage System and quick Sequential Organ Failure Assessment) was significantly worse in non-survivors, who were also significantly older (65 vs 45 years, respectively) and had haematological, biochemical, coagulation and inflammatory biomarkers more altered than survivors. Mortality predictors were invasive mechanical ventilation (IMV; OR 3.31, p<0.0001), admission to intensive care unit (ICU; OR 2.18, p<0.0001), age (OR 1.02, p<0.0001), Manchester Triage System (urgent OR 1.44, p=0.02; immediate/very urgent OR 2.02, p=0.004), baseline C reactive protein (CRP; OR 1.002, p=0.009) and antecedent of kidney disease (OR 1.58, p=0.04) CONCLUSIONS: Mortality in hospitalised patients with COVID-19 in this emerging country centre seemed to be higher than in developed countries. Patients displayed a high frequency of risk factors for poor outcome, but the need for IMV, ICU admission, older age, more severe disease at admission, antecedent of kidney disease and higher CRP levels significantly predicted mortality.

RESUMO
A large gap between the number of people with end-stage kidney disease (ESKD) who received kidney replacement therapy (KRT) and those who needed it has been recently identified, and it is estimated that approximately one-half to three-quarters of all people with ESKD in the world may have died prematurely because they could not receive KRT. This estimate is aligned with a previous report that estimated that >3 million people in the world died each year because they could not access KRT. This review discusses the reasons for the differences in treated and untreated ESKD and KRT modalities and outcomes and presents strategies to close the global KRT gap by establishing robust health information systems to guide resource allocation to areas of need, inform KRT service planning, enable policy development, and monitor KRT health outcomes.
RESUMO
OBJECTIVE: The aim of this study was to evaluate the interaction between diet quality and interleukin (IL)-6 genotypes and its association with metabolic and renal function parameters in Mexican patients with type 2 diabetes mellitus (T2DM). DESIGN AND METHODS: Using an analytical cross-sectional design, 219 patients with T2DM (92 men; age 62 ± 10 years) were evaluated for selected metabolic and renal function parameters. Diet quality according to the Healthy Eating Index was evaluated and classified as good diet or poor diet in all patients. IL-6 serum concentrations and genotypes and haplotypes for IL6-597G > A (rs180097), -572G > C (rs180096), and -174G > C (rs180095) polymorphisms were determined. RESULTS: Eighty-two percent of patients reported having a poor diet. Carriers of alleles -572C and -174C showed higher high-density lipoprotein cholesterol levels (44 ± 12 vs. 40 ± 9 mg/dL; P = .01) and lower total cholesterol levels (184 ± 33 vs. 197 ± 42 mg/dL; P = .03) than did those homozygous for G/G. Neither IL6 genotypes nor haplotypes were significantly associated with serum concentrations of IL-6. Some significant interactions between IL6 genotypes/haplotypes and diet quality were associated with body mass index, waist circumference, high-density lipoprotein cholesterol levels, and estimated glomerular filtration rate. CONCLUSIONS: Interactions between diet quality and IL6 genotypes/haplotypes were associated with the main metabolic and renal function parameters in Mexican patients with T2DM. It will be important to consider genetic profiles in designing dietary portfolios and nutritional interventions for the management of such patients.

OBJECTIVE: Obesity is clearly associated to kidney disease in adult population; however, there is scarce evidence in children and adolescents. The aim was to compare frequency of renal damage according to the presence of overweight-obesity in children and adolescents, as well as to compare nutritional and biochemical risk factors, according to the presence of kidney alterations. METHODS: Cross-sectional study; 172 children and adolescents, 6-16 years old, without malnutrition, diabetes mellitus, hypertension and independent comorbid conditions associated to obesity or kidney disease, as well as transitory causes of microalbuminuria (MA) from a Primary Health-Care Unit were included. Clinical, biochemical, anthropometric and dietetic evaluations were measured in all subjects; subsequently they were classified as normal weight, overweight and obesity groups according to sex- and age-adjusted body mass index (BMI). Glomerular filtration rate (GFR, estimated by Schwartz equation) and albuminuria (albumin/creatinine ratio) were determined. Presence of kidney alterations was measured as decreased GFR (<90 mL/min/1.73m2), hyperfiltration (>170 mL/min/1.73m2) and MA (30-300 mg/g). RESULTS: Compared with controls, subjects with overweight-obesity had significantly (P<.05) abdominal obesity (0 vs 69%), hypertension (19 vs 26%), hypertriglyceridemia (11 vs 47%), high low-density lipoprotein cholesterol (2 vs 8%) and low high-density lipoprotein cholesterol (HDL-cholesterol; 2 vs 28%), hyperuricemia (11 vs 28%) and hyperinsulinemia (8 vs 70%). Hyperfiltration and MA were present in 5 and 4 subjects with overweight/obesity, respectively, whereas decreased GFR was present in only 1 subject with obesity. Normal weight subjects had no kidney alterations. In multivariate analysis, kidney alterations were significantly predicted by higher BMI and lower HDL-cholesterol. CONCLUSIONS: Kidney alterations were observed only in subjects with overweight (3.6%) and obesity (9.9%), who additionally, displayed cardiometabolic and kidney disease risk factors more frequently than normal weight subjects.

BACKGROUND: To determine the prevalence of cardiovascular risk factors (CVRF) in healthcare workers from two tertiary-care hospitals of the Mexican Institute of Social Security, as well as their association with professional activities (PA). METHODS: Descriptive study. One-thousand eighty-nine health-care workers ≥ 18 years were included. Clinical history, physical exam, and blood tests were performed. RESULTS: Mean age 41 ± 9 years, 76% women. Hypertension prevalence was 19%, diabetes mellitus 9.6%, dyslipidemia 78%, overweight and obesity 73%, metabolic syndrome (MS) 32.5%, and smoking 19%. The following significant associations (p < 0.05) were found: MS with medical asisstants (OR: 2.73, CI 95%: 1.31-5.69) and nutritionist (OR: 2.6, CI 95%: 1.31-5.24); obesity with administrative personnel (OR: 3.64, CI 95%: 1.40-7.46); dyslipidemia with medical asisstants (OR: 2.58, CI 95%: 1.15-6.34). In the whole sample, the probability to have a vascular event in the following 10 years was 10%. CONCLUSION: Prevalence of CVRF was high in this sample of health-care workers and did not seem to be different from those in general population. Medical assistants, nutritionist, and administrative personnel displayed a higher risk. It is necessary to create programs to promote healthy lifestyle and to improve the epidemiological profile of health-care workers.
Introducción: el objetivo de este trabajo es determinar la prevalencia de los factores de riesgo cardiovascular (FRCV) y su asociación con actividad laboral (AL) en trabajadores de dos hospitales de enseñanza de tercer nivel de atención del IMSS. Métodos: estudio descriptivo que incluyó a trabajadores ≥ 18 años. Se realizó historia clínica, examen físico y pruebas de laboratorio para identificar FRCV y asociarlos con AL. Resultados: se estudió un total de 1089 trabajadores, con edad de 41 ± 9 años, el 76% fueron mujeres. La prevalencia de hipertensión fue de 19%, diabetes mellitus 9.6%, dislipidemia 78%, sobrepeso y obesidad 73%; síndrome metabólico (SM) 32.5%, tabaquismo 19%. El SM se asoció con el área de asistentes médicas (OR: 2.73, IC 95%: 1.31-5.69) y nutrición/dietética (OR: 2.6, IC 95%: 1.31-5.24). La obesidad con el área administrativa (OR 3.64 IC 95%: 1.40-7.46). La dislipidemia con el área de asistentes médicas (OR 2.58, IC 95%: 1.15-6.34). La probabilidad de sufrir evento vascular en 10 años fue de 10%. Conclusiones: la prevalencia de FRCV fue alta y no es diferente a la de la población general. Las actividades laborales en riesgo fueron: asistentes médicas, nutricionistas y personal administrativo. Es necesario reorientar programas de promoción de la salud en unidades médicas para mejorar el perfil epidemiológico de los trabajadores.

BACKGROUND: Pre-diabetes in young people is frequently unrecognized or not treated on time, with the consequent loss of opportunity for diabetes prevention. In Mexico, there is scarce information about the prevalence of pre-diabetes in young adults. OBJECTIVE: To determine the prevalence and risk factors for pre-diabetes in young Mexican adults in primary health care. METHODS: In a cross-sectional study, 288 subjects, aged 18-30 years, from a primary care unit were included. Pre-diabetes was diagnosed (according to the criteria of the American Diabetes Association) as impaired fasting glucose (8-12 hours fasting plasma glucose level: 100-125 mg/dl) or impaired glucose tolerance (140-199 mg/dl after a 2-hour oral glucose tolerance test). RESULTS: Prevalence of pre-diabetes was 14.6% [95% confidence interval (CI): 10.7-19.2], whereas that of diabetes was 2.4% (95% CI: 1.0-4.9). A high proportion of patients had history of obesity, diabetes, hypertension and consumption of tobacco and alcohol. Pre-diabetic patients were older than normoglycaemics (pre-diabetic patients: 26±4 years versus normoglycaemic subjects: 24±3 years, P = 0.003) and had higher body mass index (BMI; pre-diabetic patients: 29.4±6.8 kg/m(2) versus normoglycaemic subjects: 26.8±5.8 kg/m(2); P = 0.009), particularly in the case of men (pre-diabetic men: 29.3±7.0 kg/m(2) versus normoglycaemic men: 26.4±5.1 kg/m(2); P = 0.03). Although waist circumference showed a trend to be higher among pre-diabetics, no significant differences were found according to gender (among males: pre-diabetics: 99.5±18.8 cm versus normoglycaemics: 93.3±14.4 cm, P = 0.09; among females: pre-diabetics: 91.5±13.8 cm versus normoglycaemics: 85.8±15.9 cm, P = 0.16). Only age and BMI were significantly associated with the presence of pre-diabetes. CONCLUSIONS: Almost 15% of these young adults had pre-diabetes. Many modifiable and non-modifiable risk factors were present in these patients, but only age and a higher BMI were independent variables significantly associated with pre-diabetes. Timely interventions in primary health care are needed to prevent or delay the progression to diabetes.
