RESUMEN
We hypothesized that higher scores on the dietary inflammatory index (DII) would be associated with a lower glomerular filtration rate (GFR). This cross-sectional study included 2098 participants from Mexican Teachers Cohort Study, the Health Workers Cohort Study, and the Comitán Study belonging to the RenMex consortium. Energy-adjusted DII scores were estimated using a semi-quantitative food frequency questionnaire (FFQ). eGFR was estimated by the CKD Epidemiology Collaboration equation. Quantile regression models and ordered regression models were estimated to assess the associations of interest. Median age of study participants was 47 years, median eGFR was 102.9 mL/min/1.73m2, and the median energy-adjusted DII was 0.89 (range, -2.25, +4.86). The median eGFR was lower in participants in the highest percentile of DII compared to those in the lowest percentile (103.8 vs 101.4). We found that continuous and categorical energy-adjusted DII scores were associated with lower eGFR, especially at the lower percentiles. In adjusted ordered logistic regression, we found that the highest DII category was associated with 1.80 times the odds of belonging to the mildly decreased eGFR category or moderately decreased eGFR category compared lowest DII category (OR: 1.80, 95%CI 1.35, 2.40). A high DII score was associated with a lower eGFR among the Mexican population. Additional studies are crucial to validate these findings and explore potential strategies to reduce the consumption of pro-inflammatory foods as a preventive approach for chronic kidney disease (CKD).

OBJECTIVE: Periodontitis ranks sixth as a type 2 diabetes (T2D) complication. According to its severity, it may cause pain, discomfort and tooth loss. The aim of this study was to evaluate the impact of self-reported periodontal status on the Oral Health Related Quality of Life (OHRQoL) of people with T2D. METHODS: A cross-sectional study was conducted involving seventy-nine adults with T2D who visited the Metabolic Syndrome clinic at the Cosío Villegas National Institute of Respiratory Diseases in Mexico City between August and November 2010. The OHRQoL was evaluated with the shortened Oral Health Impact Profile (OHIP-EE14). Periodontitis was measured by self-report, probing depth (PD), and clinical attachment loss (CAL). The association between self-reported periodontal status and OHRQoL was evaluated with binomial regression models. RESULTS: Mean age of the participants was 60,4 years (SD=9,6); diabetes duration was 10,1 years (SD=6,6). The OHRQoL was associated with self-perception of bad breath (RR=1,58; p=0,025), self-perception of poor gum health (RR=1,66; p=0,016), dissatisfaction with chewing ability (RR=2,22; p≤0,001), tooth loss due to mobility (RR=1,74; p=0,019), and presence of 20 teeth or less (RR=1,57; p=0,045). CONCLUSIONS: OHRQoL is associated with self-report of bad breath, poor gum health and dissatisfaction with chewing ability in people with T2D, which suggests that self-perceived oral conditions represent signs and symptoms of functional and psychological impairment related to severe periodontitis.
OBJECTIVE: La periodontitis es la sexta complicación de la diabetes tipo 2 (DT2); dependiendo de su severidad puede causar dolor, incomodidad o hasta pérdida dental. El objetivo del estudio fue evaluar el impacto del estado periodontal autorreportado en la Calidad de Vida Relacionada con la Salud Oral (CVRSO) en personas con DT2. METHODS: Se realizó un estudio transversal que incluyó a setenta y nueve adultos con DT2 atendidos en la Clínica de Síndrome Metabólico del Instituto Nacional de Enfermedades Respiratorias Cosío Villegas en la Ciudad de México, entre agosto y noviembre de 2010. La CVRSO se evaluó con el cuestionario Perfil de Impacto en la Salud Bucal acortado (OHIP-EE14). La periodontitis se evaluó por autorreporte, profundidad al sondeo (PS) y pérdida de inserción clínica (PIC). La asociación entre estado periodontal autorreportado y CVRSO se evaluó con modelos de regresión binomial negativa. RESULTS: La edad promedio fue de 60,4 años (DE=9,6); la duración de diabetes de 10,1 años (DE=6,6). La CVRSO se asoció con la autopercepción de mal aliento (RR=1,58, p=0,025), autopercepción de mala salud de las encías (RR=1,66, p=0,016), insatisfacción de la habilidad para masticar (RR=2,22, p≤0,001), pérdida de algún diente con movilidad previa (RR=1,74, p=0,019) y 20 dientes presentes o menos (RR=1,57, p=0,045). CONCLUSIONS: La CVRSO se asocia con el autorreporte de mal aliento, mala salud de las encías e insatisfacción de la habilidad para masticar en personas con DT2; esto sugiere que las condiciones bucales autopercibidas representan signos y síntomas de deterioro funcional y psicológico relacionados con la periodontitis severa.

BACKGROUND & AIMS: To evaluate the association between soft drinks (SDs) consumption and estimated glomerular filtration rate (eGFR) in a Mexican adult population. METHODS: We used data from the RenMex consortium (n = 2095) that included the Mexican Teachers Cohort Study (34-65 years), the Health Workers Cohort Study (18-90 years), and the Comitán Study (19-91 years). In this cross-sectional study, we assessed SDs consumption (cola and flavored soda) using a food frequency questionnaire (FFQ) and estimated eGFR using the CKD Epidemiology Collaboration equation. Quantile regression was used to assess the association between SDs consumption and eGFR with eGFR as a continuous variable. Multinomial logistic regression models were used for eGFR categories derived from quantile regression (mildly decreased eGFR, ≥72.9-87.9 mL/min/1.73 m2 and moderately decreased eGFR, <72.9 mL/min/1.73 m2). RESULTS: Mean age of study participants was 47.2 years, 67.5% were women, and 12.2% had diabetes. eGFR was <60 mL/min/1.73 m2 in 3.7% of study participants. Mildly decreased eGFR was present in 14.8%, and moderately decreased eGFR was present in 10.1% of study participants. Quantile regression results showed that SDs consumption was associated with lower eGFR at the 10th, 25th, 50th and 75th percentile. Based on the final adjusted multinomial model, ≥7 servings/week was positively associated with moderately decreased eGFR relative to <1 serving/week (Relative Risk Ratio = 1.95; 95% CI: 1.07-3.57). CONCLUSION: Our results suggest that higher SDs consumption is associated with lower eGFR. Encouraging healthy dietary choices should be part of the management and prevention of CKD.

Purpose: To evaluate the risk factors associated with diabetic macular edema (DME) in patients with a recent type 2 diabetes mellitus (T2DM) diagnosis. Patients and Methods: We conducted a case-control study at a third-level hospital in Mexico City. We enrolled patients ≥18 years old, with T2DM less than five years of diagnosis, without disabling complications, and non-smokers. The control group was patients with diabetic retinopathy and without macular edema (DR-DME). Cases were patients with DR+DME. We measured fasting glucose, creatinine, lipid profile, urinary albumin/creatinine ratio (ACR), and HbA1c. An ophthalmological examination consisted of visual acuity measurement, digital three-field fundus photography with an automatic non-mydriatic camera, slit lamp, and Optical coherence tomography (OCT) examination. Results: 183 and 61 patients with DR-DME and DR+DME, respectively, were included in the analysis. The prevalence of mild DR was higher in the DR-DME group, but the frequencies of moderate and severe retinopathy were higher in the DR+DME group. Patients in the DR-DME group had better vision than those in the DR+DME group. Logistic regression analysis revealed that age (OR, 1.07), HbA1c (OR, 1.19), and Albumin-to-Creatinine Ratio (ACR) > 30 mg/g (OR, 3.37) were associated with an increased possibility of DME compared to DR-DME. Conclusion: Our study provides insights into the association between risk factors and DME. We found a statistically strong association between HbA1c levels, age, and ACR. Patients with poor metabolic control should undergo an extensive medical examination to screen for DME, which may be related to the chronicity of DM and renal damage.
RESUMEN
PURPOSE: The purpose of this double-masked, parallel randomised controlled trial was to compare the recurrence rate and other outcomes between conjunctival-limbal autograft (CLAu) and mini-simple limbal epithelial transplantation (mini-SLET) after excision of pterygium. METHODS: Eligibility criteria for participants was the presence of a primary nasal pterygium extending equally to or greater than two millimetres on the cornea on its horizontal axis from the nasal limbus. The participants were allocated into two groups (CLAu and mini-SLET) using simple randomisation with a table of random numbers. Participants and the outcome assessor were masked to the intervention. The study protocol is listed and available on https://clinicaltrials.gov (Identifier: NCT03363282). RESULTS: A total of 61 eyes were enrolled in the study, 33 underwent CLAu (group 1) and 28 mini-SLET (group 2), all eyes were analysed in each group. At 2, 3, 6 and 12 months the CLAu group exhibited a recurrence of 0%, 6.1%, 8.1% and 8.1%, while the mini-SLET exhibited a recurrence of 0%, 17.9%, 50% and 53.5% (p<0.05). There were no intraoperative or postoperative complications in either of the two groups. CONCLUSION: The findings of this study suggest that mini-SLET has a higher recurrence rate and provides no advantage over CLAu in the treatment of primary pterygium.

Abstract Objective: To determine the prevalence of HIV in individuals by analyzing the influence of social determinants and sexual risk behaviors, in order to estimate the crude and adjusted risks of being HIV positive in the municipality of Solidaridad, state of Quintana Roo, Mexico. Method and Materials: A cross-sectional study was conducted in the municipality of Solidaridad, Quintana Roo, Mexico. Third and fourth generation HIV rapid tests were performed. Descriptive statistics, measures of association (OR and 95 % CI) and p value were calculated for each stratum. Logistic regression models were performed to determine the risk factors associated with being HIV positive in the tests. Results: The sample consisted of 4,800 people, of whom 3,030 were men (63.12%); the mean age was 32.6 years (SD 14.96). The variables included in the multivariate model for being HIV positive are: men who have sex with men with OR=61.20, age 30-39 years OR=1.72, having anal sex OR=2.21, and as a protective factor having health service OR =0.42. Conclusions: This study confirms already known social determinants such as being male and being in economically active age and sexual practices such as: having anal sex and men with men. Being entitled to health services was shown to be the only protective factor.

Contar con derechohabiencia se muestra como único factor protector.
RESUMEN
Diabetic retinopathy (DR) is the major microvascular complication of diabetes and causes vitreous traction and intraretinal hemorrhages leading to retinal detachment and total blindness. The evolution of diabetes is related to exacerbating inflammation caused by hyperglycemia and activation of inflammatory cells. Neutrophils are cells able to release structures of extracellular DNA and proteolytic enzymes called extracellular traps (NETs), which are associated with the persistence of inflammation in chronic pathologies. The purpose of the study was to determine the usefulness of neutrophil traps as indicators of DR progression in patients with type 2 diabetes (T2DM). We performed a case-control study of seventy-four cases classified into five groups (non-proliferative DR, mild, moderate, severe, and proliferative) and fifteen healthy controls. We found correlations between NETs and a diagnostic time of T2DM (r = 0.42; p < 0.0001), fasting glucose (r = 0.29; p < 0.01), glycated hemoglobin (HbA1c) (r = 0.31; p < 0.01), estimated glomerular filtration rate (eGFR) (r = -0.29; p < 0.01), and plasma osmolarity (r = 0.25; p < 0.01). These results suggest that due to NETs being associated with clinical indicators, such as HbA1c and eGFR, and that NETs are also associated with DR, clinical indicators might be explained in part through an NET-mediated inflammation process.
RESUMEN
BACKGROUND: Data on visual impairment (VI) in patients with diabetes are necessary in order to guide economic and human resources for reducing its prevalence. OBJECTIVE: To estimate the prevalence of diabetic retinopathy-related VI in patients with type 2 diabetes in a hospital-based setting. MATERIAL AND METHODS: Cross-sectional study carried out from 2014 to 2019 in an ophthalmology outpatient clinic. Any VI was defined as corrected pin-hole visual acuity in the better eye of ≥ 0.24 logMAR. The presence of diabetic retinopathy (DR), diabetic macular edema (DME) and cataract was evaluated. RESULTS: A total of 840 patients were included; median diabetes duration was 15 years. The prevalence of VI was 30%. DR was found in 62% of patients (30% had sight-threatening DR [STDR]), 17% had referable DME, and 3%, cataracts. The odds ratio for moderate or worse VI was 9.02 for STDR (p < 0.001), 5.89 for referable DME (p = 0.001), and 2.51 for cataract (p = 0.006). CONCLUSION: Thirty percent of participants had some degree of VI. Moderate or worse VI showed a strong association with STDR and referable DME.
ANTECEDENTES: Los datos sobre discapacidad visual (DV) en pacientes con diabetes son necesarios para orientar los recursos económicos y humanos que disminuyan su prevalencia. OBJETIVO: Estimar la prevalencia de DV relacionada con retinopatía diabética en pacientes con diabetes tipo 2 en un entorno hospitalario. MATERIAL Y MÉTODOS: Estudio transversal realizado de 2014 a 2019 en una consulta externa de oftalmología. Cualquier DV se definió como agudeza visual corregida con agujero estenopeico en el ojo con mejor visión (≥ 0.24 logMAR). Se evaluó la presencia de retinopatía diabética, edema macular diabético (EMD) y cataratas. RESULTADOS: Se incluyeron 840 pacientes; la mediana de duración de la diabetes fue de 15 años. La prevalencia de DV fue de 30 %. Se encontró retinopatía diabética en 62 % (30 % tenía retinopatía diabética que amenazaba la visión [RDAV]); 17 %, EMD y 3 %, cataratas. La razón de momios para DV moderada o de mayor gravedad fue de 9.02 para RDAV (p < 0.001), 5.89 para EMD referible (p = 0.001) y 2.51 para catarata (p = 0.006). CONCLUSIÓN: Treinta por ciento de los participantes tenía algún grado de DV. La DV moderada o de mayor gravedad mostró una fuerte asociación con RDAV y EMD referible.

RESUMEN
Vaccines have been recognized as having a central role in controlling the COVID-19 pandemic; however, most vaccine development research is focused on IgG-induced antibodies. Here, we analyzed the generation of IgGs related to SARS-CoV-2 and the changes in B- and T-lymphocyte proportions following vaccination against COVID-19. We included samples from 69 volunteers inoculated with the Pfizer-BioNTech (BNT162b2), Astra Zeneca (AZD1222 Covishield), or Sputnik V (Gam-COVID-Vac) vaccines. IgGs related to SARS-CoV-2 increased after the first vaccine dose compared with the nonvaccinated group (Pfizer, p = 0.0001; Astra Zeneca, p < 0.0001; Sputnik V, p = 0.0089). The results of the flow cytometry analysis of B- and T-lymphocytes showed a higher proportion of effector-memory B-lymphocytes in both first and second doses when compared with the nonvaccinated subjects. FcRL4+ cells were increased in second-dose-vaccinated COVID-19(−) and recovered COVID-19(+) participants when compared with the nonvaccinated participants. COVID-19(−) participants showed a lower proportion of follicular helper T-lymphocytes (TFH) in the second dose when compared with the first-vaccine-dose and nonvaccinated subjects. In conclusion, after the first vaccine dose, immunization against SARS-CoV-2 induces IgG production, and this could be mediated by TFH and effector-memory B-lymphocytes. Our data can be used in the design of vaccine schedules to evaluate immuno-bridging from a cellular point of view.
RESUMEN
OBJECTIVE: To harmonize participants' information from five epidemiological studies. MATERIALS AND METHODS: The Mexican Consortium of Epidemiological Studies for the Prevention, Diagnosis, and Treatment of Chronic Kidney Disease (RenMex, by its Spanish acronym) was established in 2018. RenMex is a consortium of five studies: The Mexican Teachers Cohort Study; the Mexico City Diabetes Study; the Health Workers Cohort Study; the Comitán Study; and the Salt Consumption in Mexico Study, which assessed baseline serum creatinine, albumin, and C-reactive protein, all performed with standardized techniques. RESULTS: RenMex includes 3 133 participants, with a mean age of 44.8 years, 68.8% women, 10.8% with a previous medical diagnosis of type 2 diabetes, and 24.1% living with obesity. CONCLUSIONS: In the future, RenMex will work on more detailed analyses with each cohort allowed to opt in or out for each topic according to their individual data.

AIMS: To evaluate a bi-national consulate-based teleophthalmology screening service for diabetic retinopathy (DR) among Mexican migrants in the U.S. METHODS: Adult visitors (n=508) at Mexican consulates in California with self-reported diabetes underwent questionnaires and fundus photography. Photographs were graded for DR by retina fellows in Mexico via teleophthalmology. Participants were contacted with results and provided referrals when necessary. RESULTS: Nearly all (97.6%) participants were aware that diabetes can cause vision loss. One-quarter (24.4%) had undergone an eye examination in the past year. Barriers to care were cost (53.9%) and insurance (45.6%). Most (85.4-91.1%) reported that Spanish-speaking providers and provision of screening in primary care would increase participation in screening. Any DR, vision-threatening DR, or proliferative DR were found in 30.2%, 9.9%, and 5.4% of participants, respectively. Nearly one-fifth (19.5%) received referrals. CONCLUSIONS: Screening in Mexican consulates may improve DR detection and treatment among Mexican migrants in the U.S.

PURPOSE: To explore corneal cooling as a method of pain management in corneal-accelerated collagen cross-linking. METHODS: This was a prospective and interventional randomized clinical trial registered in the National Institutes of Health Clinical Trials through the identifier NCT030760770. The research was conducted at the Institute of Ophthalmology "Conde de Valenciana." A total of 98 patients were randomly assigned to one of the following 2 groups: cold riboflavin (4°C) group or control group (riboflavin at room temperature). The inclusion criteria were patients of any sex, older than 18 years of age with keratoconus diagnosis who needed management with cross-linking in both eyes because of the evidence of progression. The exclusion criteria were patients who had cross-linking without epithelial debridement, unilateral cross-linking, or any other ocular pathologies besides keratoconus and any cognitive incapacity that would make the understanding of the pain test difficult. The main outcome measures were pain, tearing, photophobia, foreign body sensation, and irritation. RESULTS: At 2 hours post-op, pain in the case and control groups was 3.80 ± 3.00 and 8.08 ± 2.21 (P < 0.05), tearing was 1.56 ± 1.96 and 8.29 ± 2.42 (P < 0.05), photophobia was 5.44 ± 3.57 and 7.83 ± 2.64 (P < 0.05), foreign body sensation was 2.20 ± 2.78 and 6.54 ± 2.73 (P < 0.05), and irritation was 3.48 ± 2.98 and 6.79 ± 3.00 (P < 0.05), respectively. A statistical significant difference was maintained in pain values on day 1 (2.79 ± 3.09 and 4.91 ± 3.27 [P < 0.05]), 2 (2.54 ± 2.41 and 4.00 ± 2.43 [P < 0.05]), and 4 (0.45 ± 0.76 and 1.22 ± 1.67 [P < 0.05]). CONCLUSIONS: This study demonstrated that pain and associated symptoms decreased significantly in the riboflavin 4°C group.

Materials and methods: Cross-sectional study conducted in Comitán, Chiapas, from 2010 to 2012, comprising 1 858 subjects aged ≥20 years. We evaluated proximal, intermediate, and structural social determinants. Results: The prevalence of overweight and obesity was 37.9 and 16.5%, respectively. The probability of overweight and obesity was higher in participants with ≥primary school, self-reported non-indigenous origin, and medium level of marginalization compared with those with <primary school, self-reported indigenous origin, and high/very high level of marginalization. Conclusion: The probability of overweight and obesity was higher in population with more favorable social conditions, which may be partially explained by changes in the traditional lifestyle with greater access to high energy foods and physical inactivity.

OBJECTIVE: To determinate the prevalence of hearing loss (HL) and visual impairment (VI) among adult population from Tlaxcala, Mexico. MATERIALS AND METHODS: A populationbased cross-sectional study comprising persons 50 years and older was conducted in 2013. Self-reported HL was measured using the Hearing Impairment Inventory for the Elderly (SHIIE) questionnaire; VI was determined using the Snellen tumbling E chart. RESULTS: 900 women and 611 men (mean age 66.1 years) were included. 481(31.8%) individuals had HL (415 alone and 66 combined with VI). Prevalence of HL alone and together with VI was associated with age (per two years, OR=1.03 and OR=1.18, respectively) and self-reported poor health status (OR=1.90 and OR=3.69, respectively). CONCLUSIONS: The high prevalence of these disabilities calls for the implementation of public health interventions that help to reduce its impact in the population.
OBJETIVO: Determinar la prevalencia de discapacidad auditiva (DA) y visual (DV) en adultos del estado de Tlaxcala, México. MATERIAL Y MÉTODOS: Estudio transversal de base poblacional realizado en 2013 que incluye sujetos ≥50 años de edad. La DA se evaluó por autorreporte con el cuestionario Hearing Impairment Inventory for the Elderly (SHIIE); la DV se midió usando la cartilla E rotatoria de Snellen. RESULTADOS: Se evaluaron 900 mujeres y 611 hombres (media=66.1 años). El 31.8% (481) tenía DA (415 sola y 66 con DV). La prevalencia de DA sola o con DV se asoció con edad (por cada dos años, RM=1.03 y RM=1.18, respectivamente) y con autorreporte del estado de salud deficiente (RM=1.90 y RM=3.69, respectivamente). CONCLUSIONES: Se requiere la implementación de intervenciones en salud pública que reduzcan el impacto de estas dos condiciones en la población.

Abstract: Objective: To determinate the prevalence of hearing loss (HL) and visual impairment (VI) among adult population from Tlaxcala, Mexico. Materials and methods: A population-based cross-sectional study comprising persons 50 years and older was conducted in 2013. Self-reported HL was measured using the Hearing Impairment Inventory for the Elderly (SHIIE) questionnaire; VI was determined using the Snellen tumbling E chart. Results: 900 women and 611 men (mean age 66.1 years) were included. 481(31.8%) individuals had HL (415 alone and 66 combined with VI). Prevalence of HL alone and together with VI was associated with age (per two years, OR=1.03 and OR=1.18, respectively) and self-reported poor health status (OR=1.90 and OR=3.69, respectively).
