RESUMO
BACKGROUND: The concept of food addiction describes the difficulties of some individuals with regard to food consumption. OBJECTIVE: To determine the frequency of food addiction and its association with body mass index (BMI), calorie consumption and therapeutic control in patients with newly-diagnosed type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS: A total of 1,080 patients with T2DM were included. The degree of metabolic control was determined with the levels of glycated hemoglobin, low-density lipoprotein cholesterol and blood pressure. Daily caloric consumption was estimated with a semi-quantitative questionnaire of food consumption frequency. RESULTS: Nearly all patients showed overweight (40.5 %) and obesity (49.1 %). The frequency of food addiction was 54.2 % (56.9 % in women and 48.9 % in men). Food addiction was associated with BMI (OR = 1.89, p ≤ 0.05), high caloric intake (OR = 1.14, p ≤ 0.05) and glycated hemoglobin > 7 % (OR = 1.43, p ≤ 0.05). CONCLUSIONS: Food addiction is common in patients with overweight/obesity and newly-diagnosed T2DM, and is associated with higher-than-recommended caloric consumption, obesity degree and poor metabolic control.
ANTECEDENTES: El concepto de adicción a la comida describe las dificultades de algunos individuos respecto al consumo de comida. OBJETIVO: Determinar la frecuencia de la adicción a la comida y su asociación con el índice de masa corporal (IMC), consumo de calorías y control terapéutico en pacientes con diabetes mellitus tipo 2 (DMT2) de diagnóstico reciente. MATERIAL Y MÉTODOS: Se incluyeron 1080 pacientes con DMT2. Se determinó el grado de control terapéutico con niveles de hemoglobina glicada, colesterol de baja densidad y presión arterial. El consumo diario de calorías fue estimado con un cuestionario semicuantitativo de frecuencia de consumo de alimentos. RESULTADOS: Casi todos los pacientes mostraron sobrepeso (40.5 %) y obesidad (49.1 %). La frecuencia de adicción a la comida fue de 54.2 % (56.9 % en mujeres y 48.9 % en hombres). La adicción a la comida se asoció a IMC (RM = 1.89, p ≤ 0.05), alto consumo calórico (RM = 1.14, p ≤ 0.05) y hemoglobina glicada > 7 % (RM = 1.43, p ≤ 0.05). CONCLUSIONES: La adicción a la comida es frecuente en pacientes con sobrepeso/obesidad y DMT2 recientemente diagnosticada y se asocia al consumo calórico superior a lo recomendado, grado de obesidad y pobre control terapéutico.

RESUMO
PURPOSE: The COVID-19 Fear Scale (FCV-19S) allows screening in general population; however, there is no specific instrument in our population for screening in the perinatal period that considers fear related with COVID-19 and offspring well-being. We aimed to validate the FCV-19S modified for application during the perinatal period. MATERIALS AND METHODS: Analytical, cross-sectional design. After signing consent, women 18-45 years were included. Internal consistency was calculated with Cronbach's alpha, external validity using the Hospital Anxiety and Depression Scale (HADS), factorial analysis and intraclass correlation coefficient for re-test. RESULTS: The sample included 178 women, mean age 31.04 ± 5.9. We obtained internal consistency with Cronbach's alpha = 0.873 (95%CI, 0.842-0.899). Spearman's Rho coefficient was 0.207 (p= .013). All the elements were statistically significant for the polychoric correlation (p<.001). Reliability test-retest with intraclass correlation was 0.873. CONCLUSIONS: The version of FCV-19S modified with eight items is a valid measurement instrument for application during the perinatal period, showing adequate internal consistency and external validity with HADS as measure of concurrence to identify anxiety related with COVID-19 during the perinatal period.

INTRODUCTION: The fear of COVID-19 scale (FCV-19S) is used to screen for symptoms of anxiety and depression related to COVID-19 in the general population; it consists of seven questions with Likert-type answers (1-5). Our objective was to validate FCV-19S Spanish version in the Mexican general population. MATERIAL AND METHODS: Analytical, cross-sectional design. Three-hundred and six subjects from the general population were included during 2020 after having signed informed consent. Barlett and Kaiser-Meyer-Olkin (KMO) sphericity tests were applied. Reliability was calculated with Cronbach's alpha, and external validity, using the Hospital Anxiety and Depression Scale and Pearson's correlation coefficient for retest. RESULTS: The general population sample included 306 participants; 64.4 % were women (n = 197), mean age was 32 years (18-68). We obtained a KMO = 0.848, internal consistency with Cronbach's alpha = 0.870 (95% CI: 0.848-0.891), a rho coefficient of 0.508 (p < 0.001) and external validity of 0.151 (p = 0.008). Confirmatory analysis showed: χ2 = 22.802 (df = 13) with CMIN-DF = 1.900 (p ≤ 0.001), GFI = 0.972, CFI = 0.901, RMSEA = 0.062 (90% CI: 0.019-0.100) and TLI = 0.827. CONCLUSIONS: According to our findings, the scale shows adequate psychometric properties: reliability, internal consistency, correlation with subsequent measurements and convergence validity, for initial screening of the Mexican general population.

BACKGROUND AND OBJECTIVE: Cardiovascular disease (CVD) is the main cause of death in children with chronic kidney disease (CKD). Inflammation and endothelial dysfunction (ED) are found in the majority of these patients and are factors associated to CVD. Flow mediated dilatation (FMD) is a surrogate marker validated for evaluating ED. Our objective was to identify risk factors associated to ED in children with CKD. MATERIALS AND METHODS: Children 2-16 years of age were studied. Clinical information and biochemical variables were gathered, including intact parathyroid hormone (iPTH), interleukins 6 and 1b, high sensitivity C reactive protein (hsCRP), reduced glutathione, nitric oxide, malondialdehyde and homocysteine. FMD was measured, and considered altered if <7%. RESULTS: Included were 129 patients aged 13.1⯱â¯2.6 years. FMDâ¯<â¯7% was found in 69 (52.7%). Patients with altered FMD had higher levels of triglycerides and hsCRP than those with normal FMD (145.5â¯mg/dl vs. 120.0â¯mg/dl, Pâ¯=â¯.042, y 1.24 U/L vs. 0.55 U/L, Pâ¯=â¯.007, respectively), as well as higher frequency of low iPTH (19.1% vs. 4.9%, Pâ¯=â¯.036). Levels of hsCRP correlated significantly with FMD (Rhoâ¯=â¯-0.28, Pâ¯=â¯.003). Patients with low iPTH (ORâ¯=â¯4.41, 95%CI 1.13-17.27, Pâ¯=â¯.033) and increased hsCRP (ORâ¯=â¯2.89, 95%CI 1.16-7.17, Pâ¯=â¯.022) had higher adjusted risk of having FMDâ¯<â¯7%. CONCLUSIONS: Hypertriglyceridemia, inflammation and low iPTH associated significantly with altered FMD. They are frequent, treatable risk factors for CVD.

AIMS: To describe the annual incidence of type 1 diabetes in children and adolescents insured by the Mexican Institute of Social Security, the main health provider in Mexico, during 2000-2018. METHODS: We conducted a secondary data analyses using the incidence registers from the Epidemiological Surveillance Coordination of the Mexican Institute of Social Security collected during 2000-2018. Incident type 1 diabetes cases (age 19â¯years old and below) were identified using ICD-10-CM E10 diagnostic codes. Age, sex, and geographical region and seasonal-specific incidence were calculated with their corresponding annual percentage change (APC) as well. RESULTS: In the period 2000-2018, the number of incident cases with type 1 diabetes decreased from 3.4 to 2.8 per 100,000 in insured for subjects below 20â¯years old. We observed an increase in the 2000-2006, followed by a decrease for the 2006-2018 period (APC +16.1 and -8.7 respectively). Females and children <5â¯years old had a significant decrease in the incidence rate, while inhabitants in Central Mexico showed a significant increase. No difference was found in incidence between seasons. CONCLUSIONS: Our study describes significant fluctuations of the incidence of type 1 diabetes during the period 2000-2018, which appeared to correspond to influenza outbreaks, among Mexican children and adolescents.

Given that adipocytokines may play an important role in the pathophysiology of high blood pressure (HBP) and because related reports in children are scarce and controversial, we evaluated the relationship of leptin, resistin, tumor necrosis factor-α, interleukin-6, adiponectin, and interferon-γ with HBP. Materials and Methods. A total of 129 (53.8%) girls and 111 (46.2%) boys, with average ages of 10.8 ± 0.9 and 10.6 ± 1.0 years, respectively, were enrolled in a cross-sectional study. HBP was defined by systolic blood pressure (SBP) and/or diastolic blood pressure (DBP) between the 90th and 95th percentiles. A multivariate logistic regression backwards-stepwise analysis adjusted for body mass index, waist circumference, and triglyceride levels was performed to compute the association between adipocytokines and HBP. Results. Seventy-two (30.0%) participants showed HBP: 44 (61.1%) girls and 28 (38.9%) boys. Multivariate analysis showed that, irrespective of obesity, serum levels of adiponectin, but not those of other adipocytokines, are inversely associated with HBP (odds ratio 0.93; 95% CI 0.77 to 0.98, p = .04). Conclusions. Our results show that low serum adiponectin levels, but not those of other adipocytokines, are inversely associated with HBP; this association is independent of obesity.

Introduction: The prevalence of chronic complications and comorbidities in patients with type 2 diabetes (T2D) has increased worldwide. Objective: To compare the prevalence of complications and chronic comorbidities in patients with T2D at 36 family medicine units of five chapters of the Mexican Institute of Social Security (IMSS). Method: Complications (hypoglycemia, diabetic foot, kidney disease, retinopathy, ischemic heart disease, cerebrovascular disease and heart failure) and comorbidities (liver disease, cancer and anemia) were identified according to codes of the International Classification of Diseases, 10th Revision. Comparisons were made by chapter, age, gender and evolution time. Results: Complications and comorbidities were more common in subjects aged ≥ 62 years. Out of 297 100 patients, 34.9 % had any complication; microvascular complications (32 %) prevailed in the industrial North, whereas macrovascular complications (12.3 %) did in the rural East, and comorbidities (5 %) in southern Mexico City. Complications predominated in men (any complication, 30.2 %). Heart failure and comorbidities were more common in women (5.6 % and 4.9 %, respectively). Conclusions: T2D complications and comorbidities showed geographic and gender differences, and were greater with older age and longer evolution time. It is urgent for strategies for the prevention of complications and comorbidities to be reinforced in patients with T2D.

The albumin-creatinine ratio is considered an indicator of microalbuminuria, precursor to chronic kidney disease, while HbA1c is used to measure glycemic control. Given the prevalence of diabetes-related nephropathy, spot testing of albumin has long been recommended as a preventative measure, for the timely detection of microalbuminuria. However, many countries do not have this testing available in primary care, and sometimes not even in second- and third-level care. The objective of this study was to compare agreement of the microalbuminuria and HbA1c results obtained in the laboratory with 'gold standard' techniques, with those obtained on site with a 'Point of Care' DCA Vantage™ device by Siemens. Results for the albumin-creatinine ratio and HbA1c from the Siemens DCA Vantage™ point of care device were compared with those from standard laboratory tests in 25 family medicine units in Mexico City and Toluca, State of Mexico, in patients diagnosed with type-2 diabetes. Agreement between the albumin values of the 2 tests was 0.745 (CI 95% 0.655-0.812). Agreement between the two measurement techniques for HbA1c was 0.970 (CI 95% 0.966-0.973). The results obtained were sufficiently comparative (Ri= 0.74 for albumin-creatinine ratio and Ri = 0.97 for HbA1c) to justify the use of the point of care device. Given the high agreement between the point of care device and laboratory tests, this device could be used to identify chronic kidney disease and glycemic control for more adequate treatment in patients with diabetes, especially in remote areas.

AIMS: Describe stepwise strategies (electronic chart review, patient preselection, call-center, personnel dedicated to recruitment) for the successful recruitment of >5000 type 2 diabetes patients in four months. METHODS: Twenty-five family medicine clinics from Mexico City and the State of Mexico participated: 13 usual care, 6 specialized diabetes care and 6 chronic disease care. Appointments were scheduled from 11/3/2015 to 3/31/2016. Phone calls were generated automatically from an electronic database. A telephone questionnaire verified inclusion criteria, and scheduled an appointment, with a daily report of appointments, patient attendance, acceptance rate, and questionnaire completeness. Another recruitment log reviewed samples collected. Absolute number (percentage) of patients are reported. Means and standard deviations were estimated for continuous variables, χ2 test and independent "t" tests were used. OR and 95% CI were estimated. RESULTS: 14,358 appointments were scheduled, 9146 (63.7%) attended their appointment: 5710 (62.4%) fulfilled inclusion criteria and 5244 agreed to participate (91.8% acceptance). Those accepting participation were more likely women, younger and with longer disease duration (p<0.05). The cost of the call-center service was $3,010,000.00 Mexican pesos (â¼$31.70 USD per recruited patient). CONCLUSIONS: Stepwise strategies recruit a high number of patients in a short time. Call centers offer a low cost per patient.

OBJECTIVE: To evaluate the association of the V249I and T280M variants of CX3CR1 fractalkine gene with carotid intima-media thickness in Mexican subjects with and without type 2 diabetes. METHODS: We analyzed the V249I and T280M variants of the CX3CR1 receptor by TaqMan assays in 111 subjects with type 2 diabetes and 109 healthy controls. Hemoglobin A1c, glucose, and lipid profile were determined. RESULTS: A significant increase in carotid intima-media thickness was observed in type 2 diabetes patients (0.979 ± 0.361 mm) compared to healthy controls (0.588 ± 0.175 mm). In subjects carrying the MM variant of the T280M polymorphism, hemoglobin A1c was higher (p = 0.008). Classic risk factors for atherosclerosis showed no differences between carriers of the T280M and V249I variants. Controls with the II249 genotype associated with carotid intima-media thickness (0.747 ± 0.192 mm; p = 0.041), and this difference remained significant even after adjusting factors such as age, gender, and body mass index (OR: 7.7; 95% CI: 1.269-47.31; p = 0.027). CONCLUSIONS: V249I genotype of the fractalkine receptor showed a protector role in patients with type 2 diabetes. The T280M genotype is associated with increased carotid intima-media thickness in Mexican individuals with or without type 2 diabetes.

OBJECTIVE: The aim of this study is to determine whether insulin resistance is associated with elevation of transaminases levels and aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio in normal-weight healthy young adults. PARTICIPANTS AND METHODS: Apparently healthy nonpregnant women and men, aged 18-23 years, were enrolled in a cross-sectional study. According to the homeostasis model assessment of insulin resistance, the participants were allocated into groups of patients with (>2.5) and without (≤2.5) insulin resistance. Normal weight was defined by BMI of at least 18.5 and less than 25.0 kg/m. A multiple logistic regression analysis was carried out to determine the association between insulin resistance and elevated transaminases and AST/ALT ratio of 1 or less. RESULTS: A total of 1732 young adults were enrolled and allocated into groups with (n=287) and without (n=1445) insulin resistance. The prevalence of insulin resistance was 16.6% in the overall population. The multivariate logistic regression analysis adjusted by age, sex, waist circumference, and BMI indicated that the odds ratio (OR) between insulin resistance and elevated ALT concentrations is 1.65 [95% confidence interval (CI): 1.04-2.62, P=0.03], for AST/ALT ratio lower than 1 OR is 1.69 (95% CI: 1.27-2.26, P<0.001), and for elevated AST levels OR is 1.31 (95% CI: 0.71-2.43, P=0.377). CONCLUSION: The results of the present study suggest that insulin resistance is significantly associated with elevated ALT levels and AST/ALT ratio of lower than 1, but not with elevated AST levels.

OBJECTIVE: To compare the level of expression of the gene CTSL and its correlation with NKT cells in patients with recent-onset type 1 diabetes (T1D), their siblings, and healthy controls. METHODS: Analytical cross-sectional design. Patients with T1D < 3 months evolution, their siblings, and healthy controls were included. Percentages and absolute numbers of NKT cells were measured with expression of the CTSL gene. RESULTS: 124 subjects: with T1D (n = 48), siblings (n = 44) and controls (n = 32) were included. HbA1c was greater and C-peptide lower in T1D than the other groups and sibling age was higher (p < 0.001). There were no differences in NKT cells between T1D (0.176 ± 0.202) and controls (0.118 ± 0.133), but the percentage was higher in siblings (0.246 ± 0.188; p = 0.002). Lower level of expression of the CTSL gene associated with both absolute number (r: 0.4607; 95% CI: -0.08425 to -0.7935; p = 0.043) and percentage of NKT cells (r: 0.4540; 95% CI: -0.0927 to -0.7903; p = 0.045) in the T1D group. CONCLUSIONS: Patients with T1D have lower percentage and absolute number of NKT cells compared to their siblings. NKT cells absolute numbers are correlated with the expression of CTSL in T1D patients.

BACKGROUND: Certain HLA class II haplotypes have long been related with the risk of developing type 1 diabetes. The presence of the HLA haplotype DRB1*04/DQA1*03/DQB1*03:02, together with specific ß-cell autoantibodies, contributes to the development and/or severity of insulin deficiency in type 1 diabetes. OBJECTIVE: To evaluate the association of HLA risk haplotype HLA-DRB1/-DQA1/-DQB1 with ß-cell function and antibody markers in recent-onset type 1 diabetes patients, their siblings, and controls. METHODS: We studied recently diagnosed type 1 diabetes pediatric patients, their siblings, and healthy controls, analyzing autoantibodies (anti-glutamic acid decarboxylase, anti-IA-2, and anti-insulin), HLA risk and protector haplotypes, and ß-cell function (plasma proinsulin, insulin and C-peptide). X2, ANOVA or Kruskal-Wallis and multiple logistic regression were used to analyze data. RESULTS: We included 46 patients, 72 siblings, and 160 controls. Prevalence of anti-tyrosine phosphatase-related islet antigen 2 and anti-glutamic acid decarboxylase antibodies was higher in patients than siblings and controls. We found risk haplotype DRB1*04/DQA1*03/DQB1*03:02 in 95.7% of patients vs. 51.87% of controls; DRB1*03:01/DQA1*05/DQB1*02 in 47.8% of patients vs. 8.12% of controls; and DRB1*14/DQA1*05/DQB1*03:01 in 2.2% of patients vs. 20.0% of controls. With DRB1*04/DQA1*03/DQB1*03:02, the prevalence of antibodies was significantly higher in patients, although not within any single group. In regression model based on insulin secretion, only anti-tyrosine phosphatase-related islet antigen 2 antibodies and age were associated with the risk haplotype. CONCLUSIONS: The DRB1*04/DQA1*03/DQB1*03:02 haplotype increased the risk for lower insulin, proinsulin, and C-peptide concentrations, suggesting an association with the severity of insulin deficiency in type 1 diabetes patients. This haplotype, added to antibody positivity, is a predictor of deficient insulin secretion in a Mexican pediatric population.

INTRODUCTION: Poor metabolic control is a constant in patients with diabetes worldwide, despite resources demonstrated to achieve therapeutic targets. The object of this study was to identify causes of poor metabolic control in patients with diabetes treated in Family Medicine Clinics in metropolitan Mexico City at the Instituto Mexicano del Seguro Social. MATERIAL AND METHODS: We analyzed 638 of 1,170 patients studied between 2000 and 2006. Anthropometric variables, occurrence of infections, treatment adherence, medical prescriptions, diet, exercise, and laboratory results were recorded. RESULTS: The proportion of patients with HbA1c < 7% worsened over time: from 38.9% at baseline it decreased to 21.4% (p < 0.001); LDL cholesterol decreased from 51.9 to 12.2% (p < 0.001), and controlled blood pressure from 35.6 to 23.3% (p < 0.001). A diet high in calories was associated with poor metabolic control (OR: 2.36; 95% CI: 1.34-4.13) and treatment intensification with elevated HbA1c (OR: 2.1; 95% CI: 1.14-4.14). Treatment was not intensified in 90% of patients outside targets. Infections, non-adherence, and drugs that interfere with oral hypoglycemic agents were not associated with higher HbA1c. CONCLUSIONS: The main factors associated with higher HbA1c were: disease progression, an inadequate diet, and lack of treatment intensification. Any program designed to improve the conditions of these patients must consider these factors.

OBJECTIVE: To evaluate the effectiveness of an intensive lifestyle intervention on metabolic control in patients with type 2 diabetes. METHODS: 199 patients recently diagnosed with type 2 diabetes, with lack of metabolic control and overweight/obesity, were randomly assigned to intensive lifestyle intervention or collaborative educational program alone, with 6 months of follow-up. Intervention included 150min of physical activity a week to reduce body weight by 7%. Both groups received 16 sessions on behavior modification over the course of the 6 months. Measurements were taken at baseline, 3 and 6 months. Results were analyzed and compared. RESULTS: Significant weight loss was achieved by both groups, with greater loss in the intervention group. Those with lower baseline A1c appeared to benefit more from the educational program than intensive intervention over time. CONCLUSIONS: Both interventions produced positive if modest changes in metabolic control. These results suggest that, for weight loss and control of A1c, an intensive intervention may be more effective. PRACTICE IMPLICATIONS: The current study demonstrates the value of a systematic application of behavior modification and self-care techniques in the treatment of type 2 diabetes. It demonstrates the importance of intensive, all-inclusive treatment, and of attention to individual concerns.

OBJECTIVE: To evaluate the association of hypomagnesemia with prehypertension (preHTN) and hypertension in children. STUDY DESIGN: A total of 3954 apparently healthy Mexican children were enrolled in a cross-sectional study. Exclusion criteria were type 2 diabetes; hepatic, renal, or endocrine disease; impaired fasting glucose; chronic diarrhea; and intake of vitamins or magnesium supplements in the previous 6 months. preHTN was defined by systolic and/or diastolic blood pressure ≥90th to <95th percentile and hypertension by systolic and/or diastolic blood pressure ≥95th percentile, according to age, sex, and height percentile. Hypomagnesemia was defined by serum magnesium concentration <1.8 mg/dL (<0.74 mmol/L). To control for potential sources of bias related to age, participants were allocated into 2 groups, aged 6-10 years and 11-15 years. RESULTS: The prevalence of preHTN and hypertension was 12.2% and 6.4%, respectively, in children aged 6-10 years and 13.9% and 10.6% in those aged 11-15 years. Hypomagnesemia was identified in 59 children with preHTN (27.3%) and 52 (45.6%) with hypertension in the 6-10 year age group, and in 115 children with preHTN (36.0%) and 109 (49.6%) with hypertension in the 11-15 year age group. Adjusted multiple logistic regression analysis showed that in children in both age groups, hypomagnesemia was associated with both preHTN (6-10 years: OR, 2.18, P < .0005; 11-15 years: OR, 1.38, P = .018) and hypertension (6-10 years: OR, 4.87, P < .0005; 11-15 years: OR, 1.83, P = .0002). CONCLUSION: Our results indicate that serum magnesium level <1.8 mg/dL is significantly associated with preHTN and hypertension in apparently healthy children.

OBJECTIVE: To estimate the prevalence of cognitive impairment (CI) among patients recently diagnosed with type 2 diabetes (RDD) and to identify any relationships between CI and RDD comorbidities. METHODS: One thousand seven hundred twelve patients with RDD participated in a cross-sectional study. The patients' sociodemographic and clinical data were registered. RESULTS: The sample population had an average age of 51 ± 11 years, and 63.26% of the patients were female. CI was diagnosed in 38 patients (2.2%) and was more common among both females (2.8% vs. 1.3%, p = 0.063) and the elderly (0% at an age ≤ 30 years vs. 10.4% at an age > 70 years, p = 0.0001). Rheumatoid arthritis (present in 15.8% vs. absent in 2.1%) and asthma (13% vs. 2.1%) correlated significantly with CI based on the results of our logistic regression analysis. CONCLUSION: Age, female gender, rheumatoid arthritis and asthma are risk factors for CI in the setting of RDD.
