[Clustering of cognitive domains among older adults with HIV]. / Agrupación de dominios cognitivos en personas mayores con VIH.

Background: Age and HIV are synergistic risk factors for conditions such as HIV-associated neurocognitive disorders (HAND). Yet, it is unclear whether OAWH display different cognitive profiles for HAND. Objective: To describe the cognitive patterns of OAWH treated with combined antiretroviral therapy (cART). Methods: Cross-sectional study that included 330 participants with HIV, aged 50 years or older, cared for at a tertiary care hospital in Mexico City. A short neuropsychological test battery was used to assess a wide spectrum of cognitive functions. The optimal number of cognitive clusters was determined by the silhouette method and a minimization of the Bayesian information criterion. Results: Participants' mean age was 58.8 years (SD = 6.6), and 12.1% were women. A 3-cluster solution yielded stable Jaccard coefficients (p > 0.70). Cluster 1 showed more significant impairment in visual and verbal memory domains, whereas participants in cluster 3 showed significant impairment in language, and abstraction. Cluster 2 showed no predominance of any domain for alterations. Conclusions: There are different cognitive profiles among OAWH with HAND. These differences may be due to individual patterns of HIV-related and non-HIV-related factors.

Antecedentes: La edad y el VIH constituyen factores de riesgo sinérgicos de afecciones como los trastornos neurocognitivos asociados al VIH (TNAV). No se ha esclarecido si las personas mayores con VIH presentan perfiles cognitivos diferentes en caso de padecer TNAV. Objetivo: Describir los patrones cognitivos de adultos mayores con VIH tratados con terapia antirretroviral combinada (TARc). Métodos: Estudio transversal que incluyó a 330 participantes con VIH, de 50 años o más, atendidos en un centro hospitalario de tercer nivel en la Ciudad de México. Se utilizó una batería neuropsicológica corta estandarizada a fin de evaluar un amplio espectro de funciones cognitivas. Se determinó el número óptimo de grupos de dominios cognitivos a partir del método de la silueta y minimización del criterio de información bayesiano. Resultados: La edad promedio de los participantes fue de 58.8 años; las mujeres constituyeron 12.1 %. Una solución de tres grupos produjo coeficientes de Jaccard estables (p > 0.70). El grupo 1 mostró deterioro más significativo en la memoria visual y verbal, en tanto que el grupo 3 mostró deterioro significativo en el lenguaje y la abstracción. En el grupo 2 no se registró predominio de ningún dominio en cuanto a alteraciones. Conclusiones: Existen perfiles cognitivos diferentes entre las personas mayores con VIH y TNAV. Estas diferencias pueden deberse a patrones individuales de factores relacionados o no con el VIH.

Identification of glucose and insulin patterns during A 5-H glucose tolerance test and association with cardiometabolic risk factors.

Background: Insulin resistance is key in the pathogenesis of the metabolic syndrome and cardiovascular disease. Objective: We aimed to identify glucose and insulin patterns after a 5-h oral glucose tolerance test (OGTT) in individuals without diabetes and to explore cardiometabolic risk factors, beta-cell function, and insulin sensitivity in each pattern. Methods: We analyzed the 5-h OGTT in a tertiary healthcare center. We identified classes using latent class trajectory analysis and evaluated their association with cardiometabolic risk factors, beta-cell function, and insulin sensitivity surrogates by multinomial logistic regression analysis. Results: We included 1088 5-h OGTT performed between 2013 and 2020 and identified four classes. Class one was associated with normal insulin sensitivity and secretion. Class two showed hyperglycemia, dysinsulinism, and a high-risk cardiometabolic profile (obesity, hypertriglyceridemia, and low high-density lipoprotein [HDL] cholesterol). Class three included older individuals, a higher proportion of males, and a greater prevalence of hypertension, hyperglycemia, hyperinsulinemia, and postprandial hypoglycemia. Finally, class four showed hyperglycemia, dysinsulinism, and hyperinsulinemia; this class had the worst cardiometabolic profile (a high proportion of males, greater age, hypertension, obesity, hypertriglyceridemia, and low HDL cholesterol, p < 0.001 vs. other classes). Conclusions: The latent class analysis approach allows the identification of groups with an adverse cardiometabolic risk factor, and who might benefit from frequent follow-ups and timely multidisciplinary interventions.

Association between insulin resistance and arterial stiffness in Mexican patients without type 2 diabetes.

BACKGROUND: Central aortic arterial stiffness (CAAS) is an independent cardiovascular risk factor. Insulin resistance (IR) contributes to CAAS-associated risk. OBJECTIVE: To evaluate the association between IR and CAAS in a Mexican population without diabetes. METHODS: IR was estimated with Homeostatic Model Assessment 2-Insulin Resistance (HOMA2-IR) and other surrogate markers (Metabolic score for IR [METS-IR], Quantitative Insulin Sensitivity Check Index [QUICKI], triglycerides/glucose index [TyG], TyG*body mass index [TyG*BMI] and triglycerides/high-density lipoprotein cholesterol ratio [TG/HDL-C]). CAAS was evaluated using carotid-femoral pulse wave velocity analysis (PWVcf) and the standardized augmentation index (AI-75). Bivariate correlations were made between surrogate markers and PWVcf. Increased CAAS was defined as PWVcf above the 90th percentile. Thresholds and area under the curve (AUC) were obtained for each surrogate marker in order to evaluate their performance in estimating increased CAAS. RESULTS: Three hundred and fifty-eight patients were included. A correlation was found between HOMA2-IR and PWVcf; this correlation was replicated with other surrogate markers. METS-IR and TyG*BMI had the highest degree of correlation with PWVcf. When adjustments were made for covariates, the correlations with TyG*BMI, METS-IR, HOMA2-IR and QUICKI maintained significance. HOMA2-IR showed the strongest correlation with AI-75. METS-IR and TyG showed the best AUC. Patients with prediabetes had the highest PWVcf. CONCLUSIONS: The relationship between IR and CAAS is present before the onset of diabetes; this association may entail higher cardiovascular risk.

ANTECEDENTES: La rigidez arterial central aórtica (RACA) es un factor de riesgo cardiovascular independiente. La resistencia a la insulina (RI) contribuye al riesgo asociado a RACA. OBJETIVO: Evaluar la asociación entre RI y RACA en una población mexicana sin diabetes. MÉTODOS: La RI se estimó con HOMA2-IR y (Homeostatic Model Assessment 2-Insulin Resistance) otros subrogados (METS-IR [Metabolic score for IR], QUICKI [Quantitative Insulin Sensitivity Check Index], TyG [ratio triglicéridos/glucosa], TyG*IMC [TyG*índice de masa corporal] y TG/HDL [ratio TG/lipoproteínas de alta densidad]). Se evaluó la RACA mediante el análisis de velocidad de onda del pulso carotídeo-femoral (VOPcf) y el índice de aumentación estandarizado (AI-75). Se realizaron correlaciones bivariante entre los subrogados y la VOPcf. RACA aumentada se definió como VOPcf arriba del percentil 90. Se obtuvieron puntos de corte y área bajo la curva (ABC) para cada subrogado para estimar RACA aumentada. RESULTADOS: Se incluyó 358 pacientes. Se encontró una correlación entre HOMA2-IR y VOPcf; esta correlación se replicó con los subrogados. METS-IR y TyG*IMC tuvieron el mayor grado de correlación con VOPcf. Al ajustar, las correlaciones con TyG*IMC, METS-IR, HOMA2-IR y QUICKI mantuvieron significancia. La correlación con AI-75 fue mayor para HOMA2-IR. METS-IR y TyG mostraron la mejor ABC. Los pacientes con prediabetes tuvieron mayor VOPcf. CONCLUSIONES: La relación entre la RI y la RACA está presente desde etapas no diabéticas; esta asociación puede conllevar mayor riesgo cardiovascular.

Quality of life is significantly impaired in both secretory and non-functioning pituitary adenomas.

OBJECTIVE: To evaluate the quality of life (QoL) in patients with pituitary adenomas in comparison with healthy Mexican population QoL scores. DESIGN & MEASUREMENTS: Cross-sectional study using the short form 36 questionnaire (SF-36) in 175 patients with pituitary adenomas grouped by adenoma subtype and disease activity, and compared them with the healthy Mexican population normative QoL scores. PATIENTS: A total of 44 patients with non-functioning pituitary adenomas (NFPA), 48 with acromegaly, 53 with prolactinomas and 30 with Cushing disease (CD) were enrolled in this study. RESULTS: Mental and physical components scores (MCS & PCS) of SF-36 questionnaire were lower in patients with active disease in all adenoma subtypes (P < 0.03). A significant negative relationship between prolactin levels and MCS (r = -0.30, P < 0.01) and PCS (r = -0.41, P < 0.01) were found in prolactinomas. Patients with CD showed 24 hours urine-free cortisol levels negatively correlated with MCS (r = -0.43, P < 0.01) but not with PCS. No significant correlation was found between IGF-1 ULN and QoL scores in acromegaly. NFPA patients had lower QoL scores than patients with controlled CD, acromegaly or prolactinoma (P < 0.02). Active CD and prolactinoma have lower QoL scores in comparison of NFPA (P < 0.05). Having an adenoma, secretory or non-functioning, decrease QoL scores in comparison of results in the healthy Mexican population register. Using an adjusted-multivariate model, we confirmed that disease activity in all secretory adenomas is an independent risk factor, reducing SF-36 scores significantly. CONCLUSION: Activity in all secretory pituitary adenomas' patients decrease mental and physical QoL. However, independently of disease activity, secretory and NFPA significantly decrease QoL in comparison with healthy Mexican population QoL register.

FACTORS INFLUENCING ACHIEVEMENT OF LOW-DENSITY LIPOPROTEIN CHOLESTEROL GOALS IN MEXICO: THE INTERNATIONAL CHOLESTEROL MANAGEMENT PRACTICE STUDY.

BACKGROUND: The International Cholesterol Management Practice Study is a multinational collaborative effort to describe the effectiveness of the lipid-lowering therapy (LLT) as well as the main barriers to achieve the low-density lipoprotein cholesterol (LDL-C) goals. OBJECTIVE: The objective of the study was to investigate factors associated with the achievement of LDL-C goals in Mexico using real-life data. METHODS: This was a cross-sectional observational study from 18 physicians across different health facilities in Mexico, who provided information about their practices between August 2015 and August 2016. We included patients treated for ≥3 months with any LLT in whom LDL-C measurement on stable LLT was available for the previous 12 months. RESULTS: We included 623 patients with a mean age of 59.3 ± 12.7 years; 55.6% were women. The mean LDL-C value on LLT was 141.8 ± 56.1 mg/dL. At enrollment, 97.4% of patients were receiving statin therapy (11.3% on high-intensity treatment). Only 24.8% of the very-high cardiovascular (CV) risk patients versus 26.4% of the high risk and 52.4% of the moderate risk patients achieved their LDL-C goals. Independent factors associated with non-achievement of LDL-C goal were statin intolerance, overweight and obesity, abdominal obesity, female sex, high CV risk, use of public health-care service, metabolic syndrome, type 2 diabetes, and hypertriglyceridemia. Higher-level of education was associated with a lower risk of not achieving LDL-C goals. CONCLUSIONS: Achievement of LDL-C goals is suboptimal in Mexico, especially in patients with the highest CV risk. The main barriers to achieve the goal are easily detectable. Implementation of LLT should be adapted to the patient's needs and profile.

[Índices para la evaluación de la resistencia a la insulina en individuos mexicanos sin diabetes].

OBJECTIVE: To evaluate the correlation between subrogate index for the evaluation of insulin resistance with the M value obtained with the euglycemic-hyperinsulinemic clamp as well as their sensitivity, specificity, and positive and negative predictive values. METHOD: The euglycemic-hyperinsulinemic clamp was performed in subjects having both normal fasting glucose and glycated hemoglobin concentrations. HOMA-IR, QUICKI, HOMA2%S, TyG, TyG*body mass index (BMI) and triglyceride/HDL indexes were calculated. Correlations coefficients were estimated between indexes results and the M-value adjusted by fat-free mass. Areas under the ROC curve were constructed to evaluate overall performance, sensitivity, specificity and predictive values of the subrogate indexes. RESULTS: 57 subjects, 68.4% women, with a mean age of 32.9 ± 11 years-old were included. The subrogate index with the best correlation with the M value was HOMA2%S (r = 0.428), HOMA-IR had the greatest area under the ROC curve (0.683; 95 % confidence interval: 0.503-0.864) and TyG*BMI the best sensitivity (98.2 %) and specificity (51.1 %). CONCLUSIONS: The surrogated indexes for the evaluation of insulin resistance show a significant correlation with the M value obtained with the gold standard. Additional studies are required to determine cut-off values in Mexican population.

OBJETIVO: Evaluar la correlación entre índices subrogados de resistencia a la insulina y el valor M obtenido mediante pinza euglucémica-hiperinsulinémica, así como su sensibilidad, especificidad y valores predictivos positivo y negativo, en mexicanos sin diabetes. MÉTODO: Se realizó una pinza euglucémica-hiperinsulinémica en individuos con glucosa en ayuno y hemoglobina glucosilada normales. Se estimaron los índices HOMA-IR, QUICKI, HOMA2%S, TyG, TyG*índice de masa corporal (IMC) y triglicéridos/colesterol ligado a lipoproteínas de alta densidad. Se estimaron coeficientes de correlación de Pearson entre los resultados y el valor M ajustado por masa libre de grasa. Se construyeron curvas ROC para evaluar su desempeño y se estimaron la sensibilidad, la especificidad y los valores predictivos de los índices. RESULTADOS: Se incluyeron 57 individuos, el 68.4 % mujeres, de 32.9 ± 11 años, con IMC de 26.5 ± 3.9 kg/m2. El índice subrogado con mejor correlación con el valor M fue HOMA2%S (r = 0.428), con la mayor área bajo la curva ROC (0.683; intervalo de confianza del 95 %: 0.503-0.864) HOMA-IR, y con mejor sensibilidad (92.8 %) y especificidad (51.1 %) TyG*IMC. CONCLUSIONES: Los índices subrogados para estimar la resistencia a la insulina muestran una correlación significativa con el valor M obtenido con el método de referencia. Se requieren más estudios para determinar puntos de corte en población mexicana.

[Evaluation of Mexican 'Sicalidad' health quality program]. / Evaluación de la implementación del programa Sicalidad en México.

OBJECTIVE: To analize the implementation of the Sistema Integral de Calidad en Salud (Sicalidad) program of the Ministry of Health in the 2011. MATERIALS AND METHODS: The study follows a cross sectional design, hybrid, with a qualitative and quantitative components. A cluster probabilístic sample was used with two stages. A total of 3 034 interviews were carried out in 13 states to evaluate the implementation of the eight components of the Sicalidad program. General indexes of performance (GIP) were formulated for structure process and satisfaction of users, physicians and nurses with the program. RESULTS: The GIP with the lower score was accreditation of health facilities with a range of scores between 25.4 and 28% in the medical units evaluated; The highest range of scores was in the component of nosocomial infection prevention between 78.3 and 92%. CONCLUSION: In brief the Sicalidad components evaluated suggest problems with both structure and critical process elements in the implementation of the quality initiatives.

Evaluating the impact of mobility in COVID-19 incidence and mortality: A case study from four states of Mexico.

Introduction: The COVID-19 pandemic in Mexico began at the end of February 2020. An essential component of control strategies was to reduce mobility. We aimed to evaluate the impact of mobility on COVID- incidence and mortality rates during the initial months of the pandemic in selected states. Methods: COVID-19 incidence data were obtained from the Open Data Epidemiology Resource provided by the Mexican government. Mobility data was obtained from the Observatory for COVID-19 in the Americas of the University of Miami. We selected four states according to their compliance with non-pharmaceutical interventions and mobility index. We constructed time series and analyzed change-points for mobility, incidence, and mortality rates. We correlated mobility with incidence and mortality rates for each time interval. Using mixed-effects Poisson models, we evaluated the impact of reductions in mobility on incidence and mortality rates, adjusting all models for medical services and the percentage of the population living in poverty. Results: After the initial decline in mobility experienced in early April, a sustained increase in mobility followed during the rest of the country-wide suspension of non-essential activities and the return to other activities throughout mid-April and May. We identified that a 1% increase in mobility yielded a 5.2 and a 2.9% increase in the risk of COVID-19 incidence and mortality, respectively. Mobility was estimated to contribute 8.5 and 3.8% to the variability in incidence and mortality, respectively. In fully adjusted models, the contribution of mobility to positive COVID-19 incidence and mortality was sustained. When assessing the impact of mobility in each state compared to the state of Baja California, increased mobility conferred an increased risk of incident positive COVID-19 cases in Mexico City, Jalisco, and Nuevo León. However, for COVID-19 mortality, a differential impact of mobility was only observed with Jalisco and Nuevo León compared to Baja California. Conclusion: Mobility had heterogeneous impacts on COVID-19 rates in different regions of Mexico, indicating that sociodemographic characteristics and regional-level pandemic dynamics modified the impact of reductions in mobility during the COVID-19 pandemic. The implementation of non-pharmaceutical interventions should be regionalized based on local epidemiology for timely response against future pandemics.

Physiological Network Is Disrupted in Severe COVID-19.

The human body is a complex system maintained in homeostasis thanks to the interactions between multiple physiological regulation systems. When faced with physical or biological perturbations, this system must react by keeping a balance between adaptability and robustness. The SARS-COV-2 virus infection poses an immune system challenge that tests the organism's homeostatic response. Notably, the elderly and men are particularly vulnerable to severe disease, poor outcomes, and death. Mexico seems to have more infected young men than anywhere else. The goal of this study is to determine the differences in the relationships that link physiological variables that characterize the elderly and men, and those that characterize fatal outcomes in young men. To accomplish this, we examined a database of patients with moderate to severe COVID-19 (471 men and 277 women) registered at the "Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán" in March 2020. The sample was stratified by outcome, age, and sex. Physiological networks were built using 67 physiological variables (vital signs, anthropometric, hematic, biochemical, and tomographic variables) recorded upon hospital admission. Individual variables and system behavior were examined by descriptive statistics, differences between groups, principal component analysis, and network analysis. We show how topological network properties, particularly clustering coefficient, become disrupted in disease. Finally, anthropometric, metabolic, inflammatory, and pulmonary cluster interaction characterize the deceased young male group.

Higher Veterans Aging Cohort Study 2.0 Index Score Predicts Functional Decline Among Older Adults Living with HIV.

Living with HIV has been proposed as a risk factor for the early development of functional decline. Composite marker tools like the Veterans Aging Cohort Study (VACS) Index, which includes HIV-associated and non-HIV-related markers of disease may better reflect multiorgan system injury and potentially predict functional outcomes. Therefore, the objective of this work is to determine whether higher VACS 2.0 Index scores predicts functional decline among older adults living with HIV (OALWH). Longitudinal study, including 131 adults ages 50 or older who underwent a comprehensive geriatric assessment at baseline and follow-up, at least a year apart. Functional status was determined by the gait speed (seconds for a 4-m distance). Linear regression models were constructed to determine the relationship between VACS 2.0 Index at baseline with gait speed at follow-up adjusted for potential confounders. The median for age was 58.0 years (range 50-84), and 81.7% were male. At baseline, the median VACS 2.0 Index score was 50.4 (interquartile range 42.2-65.3). The adjusted linear regression analysis found that higher baseline VACS 2.0 Index scores were significantly associated with a decline in gait speed (p = .033) at follow-up. The results suggest that the VACS 2.0 Index works as a predictor of functional decline as showed by decline in gait speed and might serve as an easy tool to identify OALWH who might need additional resources or interventions to prevent it.

Epidemiology of diabetes mellitus in Mexico.

Type 2 diabetes is the main health problem in Mexico. The large and growing number of cases and the remarkable economic impact of the disease support this statement. The condition is expressed at an earlier age and at a lower body mass index in Mexican mestizos compared with the age and body mass index reported in Caucasians. In addition, Mexican mestizos have an increased susceptibility to developing diabetic nephropathy. The Mexican health system needs major adjustments in order to prevent and treat type 2 diabetes. Treatment is not currently based on the needs and expectations of the patient. As a result, it is insufficient, belated, and costly. Close to 20% of the preventable deaths in Mexico are caused by diabetes and related metabolic diseases. Even a small decrease in this rate could result in substantial savings for the Mexican healthcare system.

ABSTRACT Background: Insulin resistance is key in the pathogenesis of the metabolic syndrome and cardiovascular disease. Objective: We aimed to identify glucose and insulin patterns after a 5-h oral glucose tolerance test (OGTT) in individuals without diabetes and to explore cardiometabolic risk factors, beta-cell function, and insulin sensitivity in each pattern. Methods: We analyzed the 5-h OGTT in a tertiary healthcare center. We identified classes using latent class trajectory analysis and evaluated their association with cardiometabolic risk factors, beta-cell function, and insulin sensitivity surrogates by multinomial logistic regression analysis. Results: We included 1088 5-h OGTT performed between 2013 and 2020 and identified four classes. Class one was associated with normal insulin sensitivity and secretion. Class two showed hyperglycemia, dysinsulinism, and a high-risk cardiometabolic profile (obesity, hypertriglyceridemia, and low high-density lipoprotein [HDL] cholesterol). Class three included older individuals, a higher proportion of males, and a greater prevalence of hypertension, hyperglycemia, hyperinsulinemia, and postprandial hypoglycemia. Finally, class four showed hyperglycemia, dysinsulinism, and hyperinsulinemia; this class had the worst cardiometabolic profile (a high proportion of males, greater age, hypertension, obesity, hypertriglyceridemia, and low HDL cholesterol, p < 0.001 vs. other classes). Conclusions: The latent class analysis approach allows the identification of groups with an adverse cardiometabolic risk factor, and who might benefit from frequent follow-ups and timely multidisciplinary interventions.

Higher-level of education was associated with a lower risk of not achieving LDL-C goals Conclusions Achievement of LDL-C goals is suboptimal in Mexico, especially in patients with the highest CV risk. The main barriers to achieve the goal are easily detectable. Implementation of LLT should be adapted to the patient’s needs and profile.
