RESUMO

BACKGROUND: It has been documented that NSAIDs (nonsteroidal anti-inflammatory and antirheumatic drugs) reduce the effectiveness of some antihypertensive drugs. OBJECTIVE: Analyze the prescription of NSAID and the variables associated in outpatients with hypertension and explore some characteristics of the physicians. MATERIAL AND METHODS: Cross-sectional study, included patients with hypertension from the Family Medicine Unit No. 24 in Mante, Tamaulipas. From the patients, sociodemographic data, clinical history and pharmacological treatments were obtained. From the physicians, sociodemographic and academic information were collected. RESULTS: Mean age of the patients was 63 ± 11 years and 31.7% were prescribed NSAIDs. When compare exposed versus non-exposed to NSAIDs, being in uncontrolled high blood pressure, uncontrolled hypertension, multimorbidity and polypharmacy. The variables associated to the prescription of NSAIDs were: uncontrolled hypertension, multimorbidity and polypharmacy. The 56.7% of the physicians were women, 83.3% with experience >10 years and 33.3% with current certification by the Council in Family Medicine. CONCLUSIONS: The inappropriate prescription of NSAIDs revealed the need to implement actions to mitigate the potential risk for the hypertension patients to present a complication.

ANTECEDENTES: Los antiinflamatorios y los antirreumáticos no esteroideos (AINE) disminuyen la eficacia de algunos antihipertensivos. OBJETIVO: Analizar el patrón de prescripción de AINE y las variables asociadas en pacientes ambulatorios con diagnóstico de hipertensión arterial, así como explorar algunas características de los médicos prescriptores. MATERIAL Y MÉTODOS: Estudio transversal de pacientes con hipertensión de la Unidad de Medicina Familiar 24 en Ciudad Mante, Tamaulipas.

RESUMO

BACKGROUND: Aging and multimorbidity (MM) are not enough to explain patient heterogeneity and outcomes. The objective of this study was to estimate the effect of multimorbidity patterns and indicators of socioeconomic, behavioral, and functional dimensions on the risk of death in a cohort of people ≥50 years old. METHODS: We analyzed a cohort of 7,342 persons ≥50 years old from the Mexican Health and Aging Study (MHAS), stratified by age groups (50-64, 65-84, ≥85 years old). MM was defined as the co-occurrence of two or more chronic diseases (CDs), and additional analysis included functional, socioeconomic, and behavioral indicators. Prevalence was estimated using descriptive analysis. Latent class analysis (LCA) was used to identify MM patterns, and logistic regression models were performed to estimate the risk of death at two and 18 years of follow-up. RESULTS: The most prevalent conditions were chronic pain, depression, and hypertension, with 60% of the subjects exhibiting MM at the initial evaluation. In all three age groups, indicators of the functional dimension were identified as risk factors for death. Economic precariousness was an additional risk factor in the 65-84 age group while living without a partner was an added risk factor in the ≥85 age group. For the 50-64 age group, "poor" self-perception of health and lack of physical exercise were identified as long-term risk factors for death. CONCLUSION: MM is a complex phenomenon that requires the implementation of age-specific care models. Health, socioeconomic and behavioral conditions should be considered to mitigate the risk of premature death.

RESUMO

Background: Multimorbidity represents a challenge for public health because as populations age, its prevalence increases. The objectives were to describe by sex the multimorbidity patterns from 2001 to 2018 in a cohort of people ≥50 years and in a subcohort with multimorbidity to describe the trajectories and transitions. Materials and Methods: Secondary analysis of the cohort of adults ≥50 years in the Mexican Health and Aging Study. Sociodemographic, health, functionality, and mortality were analyzed. Descriptive analysis was performed, estimation of prevalence by sex and trajectories, and transitions of the multimorbidity patterns with alluvial diagrams. Results: In the full cohort, 53.3% were women and in the subcohort with multimorbidity 66.1%. In both sexes, more cases with multimorbidity were observed among people without schooling, without a job, with a fair or bad economic situation, and with fair or bad self-perception of their health. The chronic diseases (CDs) with the highest prevalence were diabetes mellitus (DM), hypertension (HT), and arthritis and the most prevalent multimorbidity patterns were HT+arthritis and DM+HT. Higher proportion of men transited early to death and the women to other patterns more complex. Conclusion: Women always had higher prevalence of multimorbidity from an early age and with more complex combinations of CDs, but men with multimorbidity died prematurely. It is important to analyze multimorbidity not only from a biological approach but also from a perspective that considers sex inequalities and allows for the development of specific interventions adapted to the particular needs of men and women.

RESUMO

BACKGROUND: The victimization of women constitutes a human rights violation and a health risk factor. The central objectives of this study were to analyze the probability of revictimization among older adult Mexican women and to examine whether child abuse (CA) and/or intimate partner violence (IPV) are associated with a greater risk of elder abuse (EA) victimization. METHODS: We conducted a secondary data analysis of 18416 women 60 and older, based on data from the National Survey on the Dynamics of Household Relationships (2016), which is national and subnational representative. A descriptive analysis was carried out using retrospective self-reports of victimization experiences (CA, IPV, and EA). The prevalence of victimization and multiple victimizations in the various stages of the lives of women, as well as of revictimization among older adult women were obtained. Bayesian logistic regression models were used to examine the associations between victimization, multiple victimization, and EA victimization. RESULTS: A total of 17.3% of the older adult women reported EA in the last year; of these, 81.0% had been revictimized and 14.0% reported CA, IPV, and EA. The risk of EA rose among women who reported a combination of psychological and sexual CA, and psychological, physical and sexual CA and psychological and sexual IPV, and a psychological, economic, physical and sexual IPV. EA was higher among women who had suffered more than one type of violence. CONCLUSION: CA and IPV, particularly sexual abuse and psychological violence, can be risk factors for EA. Screening tools used to prevent and detect EA should include questions about domestic violence over the course of a person's lifetime.

RESUMO

BACKGROUND: Thiopurines are effectively prescribed for immune and oncology diseases but their toxicity leads to severe myelosuppression. Therefore, TPMT genetic variants have been used to adjust dosing for poor and intermediate metabolizers, significantly preventing adverse drug reactions. In 2018, the Clinical Pharmacogenetics Implementation Consortium included NUDT15 rs116855232 to also guide thiopurines dosing. This variant is not present in Caucasians but have been identified in 10% of Asian and Latin American populations. Despite research efforts to portrait the world's genetic variation, few studies include the investigation of NUDT15 in large samples. METHODS: Fifteen NUDT15 and TPMT variants were retrieved for 1270 Mestizos and 20 Natives genotyped from previous studies using the GSA-Illumina microarray. After bioinformatic quality controls, genotypes were available for 12 variants, TPMT rs2842949, rs2842950, rs2842934, rs1800460, rs12201199, rs12663332, rs2518463, rs4449636, rs12529220, rs3931660, rs200591577, and NUD15 rs116855232. Allele frequencies and haplotypes were assessed using PLINK, R, and Haploview. Dosing inferences were described according to the Clinical Pharmacogenomics Implementation Consortium. RESULTS: We report relevant populations differences in actionable TPMT*3B and NUDT15 rs116855232 as the allele frequency of the former is higher in Mestizos compared to Caucasians, and for the latter we report twofold and 1.35-fold higher allele frequencies in Natives and Mestizos compared to Mexicans from Los Angeles. CONCLUSIONS: TPMT*3B and NUDT15 rs116855232 actionable markers showed population differences that ought to be considered as dosing inferences highlight the relevance of routine genotyping of these variants for the prescription of thiopurines in Mexican populations.

RESUMO

BACKGROUND: The literature refers that falls are of multifactorial origin, and some authors have proposed to classify risk factors as intrinsic and extrinsic. OBJECTIVE: To estimate the risk of falls and their association with some intrinsic and extrinsic factors in older adults who receive medical care at the Mexican Institute of Social Security. METHODS: Case-control study that included individuals of both genders aged ≥ 60 years. Cases were patients who were admitted to the emergency department of a secondary care hospital diagnosed with injury or fracture secondary to a fall; the controls were patients who attended family medicine units. Descriptive, bivariate and multivariate statistical analysis was carried out. The SPSS program, version 22.0, was used. RESULTS: Three-hundred and forty-two patients were included (171 cases and 171 controls). Mean age was 76.1 ± 8.8 years, 66 % were women and 97.1 % had self-reported chronic diseases. Differences were observed in body mass index, in the proportion of cases with cognitive impairment, use of walking devices and dependence to perform basic and instrumental activities of daily living. Adjusted multivariate analysis revealed an association between the fall event and cognitive impairment and dependence to perform instrumental activities of daily living. CONCLUSIONS: Cognitive impairment and dependence to perform instrumental activities of daily living were associated with the risk of falling.

Abstract Introduction: The physician-pharmaceutical industry relationship has been identified as an ethical problem, due to conflicts of interest motivated by the benefits that doctors receive and that can affect their clinical judgment. Objective: To identify the frequency of physicians participation in activities financed by the pharmaceutical industry (PI), their attitudes towards PI representatives (PIRs), their prescriptive behavior and the association between their characteristics and their workplace with their participation in activities financed by the PI. Method: Cross-sectional survey to internists and cardiologists. The questionnaire included characteristics of the doctors and their workplace, participation in activities financed by the PI, attitudes towards PIRs, and prescription behavior. Results: 455 questionnaires were analyzed; 78.5 % of surveyed subjects were aware of the physician-PI relationship, the majority acknowledged meeting with PIRs, 30 % indicated having received financial subsidies and 10 % considered that gifts affect their prescription. Having prior knowledge of the physician-PI relationship was associated with less participation in PI-financed educational activities. Conclusion: Practices and preferences towards the PI show the need to design strategies to avoid inappropriate prescription.

RESUMO

BACKGROUND: Mexico has the sixth-highest premature death rate from chronic kidney disease (CKD) in the world. From 1990 to 2017, the age-standardized CKD mortality rate jumped from 28.7 to 58.1 per 100,000 inhabitants, making it the second-leading cause of death that year. Medical care for the disease is inequitable, as those without health insurance have limited access to renal replacement therapy (RRT). The objective of this study is to describe the healthcare trajectories of patients with end-stage renal disease (ESRD) in a public hospital in Mexico City and the barriers they face in receiving peritoneal dialysis and haemodialysis. METHODS: This study uses a convergent mixed methods approach and is predominantly qualitative. Patients completed 199 surveys, and 42 semi-structured interviews with patients having ESRD and their families were conducted. The quantitative data were analysed using descriptive statistics, and the qualitative data were processed using a phenomenological approach. RESULTS: It was found that 76.9% of the patients received peritoneal dialysis or haemodialysis as their first RRT. Over 30% began their treatment at least a month after a health professional prescribed it. Almost 50% had been hospitalized for complications related to the disease in the previous year, and 36% had uncertainties about their treatment. Close to 64% of the haemodialysis patients received treatment intermittently. Barriers to accessing treatment, information, contact with health services, and treatment availability were identified. Patients and their families encountered economic and emotional difficulties at every phase of their search for medical care and treatment. CONCLUSION: Mexico urgently needs to implement public policies related to CKD that are primarily directed at its prevention but should also implement policies directed at slowing its progression, reducing its complications, and providing funding for uninsured patients who require RRT. These policies must be based on the perspectives of human rights and equality, and the perspectives of patients, their families and the general population should be included in the policy creation process.

RESUMO

OBJECTIVE: To describe the evolution of the burden of chronic kidney disease (CKD) in Mexico by states, sex and subtypes from 1990 to 2017. DESIGN: Secondary data analysis based on the Global Burden of Disease Study (GBD) 2017. PARTICIPANTS: Mexico and its 32 states. Data were publicly available and de-identified and individuals were not involved. METHODS: We analysed age-standardised mortality rates, years of life lost (YLL) due to premature death, years lived with disability (YLD) and disability-adjusted life years (DALY), as well as the percentage of change of these indicators between 1990 and 2017. RESULTS: From 1990 to 2017, the number of deaths, YLL, YLD and DALY due to CKD increased from 12 395 to 65 033, from 330 717 to 1 544 212, from 86 416 to 210 924 and from 417 133 to 1 755 136, respectively. Age-standardised rates went from 28.7 to 58.1 for deaths (% of change 102.3), from 601.2 to 1296.7 for YLL (% of change 115.7), from 158.3 to 175.4 for YLD (% of change 10.9) and from 759.4 to 1472.2 for DALY (% of change 93.8). The highest burden of CKD was for Puebla and the lowest for Sinaloa. It was also greater for men than women. By subtypes of CKD, diabetes and hypertension were the causes that contributed most to the loss of years of healthy life in the Mexican population. CONCLUSIONS: Mexico has experienced exponential and unprecedented growth in the burden of CKD with significant differences by states, sex and subtypes. Data from the GBD are key inputs to guide decision-making and focus efforts towards the reduction of inequities in CKD. These results should be considered a valuable resource that can help guide the epidemiological monitoring of this disease and prioritise the most appropriate health interventions.

RESUMO

AIMS: To understand the epidemiology, progression, and predictive factors of urinary incontinence (UI) in community-dwelling Mexican adults aged ≥ 50 by sex and UI subtypes (stress, urge, and mixed). METHODS: We analyzed longitudinal UI data in community-dwelling adults aged ≥ 50 (7783 women and 5843 men) for the 2012 to 2015 period of the Mexican Health and Aging Study. We estimated mixed, stress, and urgency incontinence prevalence (2012); 2-year cumulative incidence and remissions (2015); and progression (2012-2015). A multivariate analysis was undertaken to evaluate the predictive factors for UI and its subtypes by sex. RESULTS: The prevalence of UI was higher (27.7%) for women (average age 65.9 ± 9.5) than 12.5% men (average age 67.4 ± 9.3) and increased with age in both sexes (26.7% in women 50 to 59, to 48.5% in ≥ 90; and 6.8% in men 50 to 59, to 26.2% ≥ 90). The most frequent UI subtypes were mixed in women and urge in men. The cumulative incidence of UI was higher in women (22.9%) than men (12.3%) while its remission was higher in men than women. Predictive factors for UI in both sexes were depressive symptoms, a higher number of concomitant diseases and a history of falls; while advanced age was a factor only for men. CONCLUSIONS: UI is a common health problem and its prevalence and severity increase with age. Addressing modifiable risk factors such as depression and falls could decrease the prevalence and incidence of UI and its subtypes. Further studies should also focus on the relationship between mixed UI and male mortality.

RESUMO

OBJECTIVE: To examine the associations between sociodemographic, health and disability-related factors and the perception of environmental barriers outside the home environment by individuals with permanent disabilities in Mexico. METHODS: In this cross-sectional, population-based study, we used data from the 2010 National Survey of Perceptions of Disability in the Mexican Population of 2,041 participants older than 18 with permanent disability. The perceptions of barriers take into consideration the challenges of getting around and using transportation outside the home environment. The covariates consisted of sociodemographic, health-related and disability-related factors. Multivariate logistic regression was used. RESULTS: The perception of environmental barriers outside the home environment was associated with being a woman, living in an urban area, speaking an indigenous language, experiencing emotional symptoms, having walking/movement, visual or self-care disabilities, having severe/extreme disability, having disability caused by illness, using physical devices, and receiving assistance and care in the home environment. CONCLUSIONS: This information is valuable for the design of public policies and programs that promote the participation of individuals with permanent disabilities, a high-priority issue in low- and middle-income countries.

RESUMO

Introduction: The relevance of medications for health depends on their quality, accessibility and appropriate use. Objective: To determine the potential therapeutic value of antibiotics that are not included in the World Health Organization Essential Medicines List (EML) but that are part of the National Essential Medicines List (NEML) of the Mexican Ministry of Health, and categorize them according to their intrinsic value. Method: Descriptive analysis of antibiotics not included in the 2013 World Health Organization EML; literature review to obtain efficacy and safety evidence; and application of quality and intrinsic value scales. Results: Four hundred and fifty-two abstracts were identified for 19 antibiotics; 56.9 % were excluded; 195 clinical trials were reviewed in full-text articles, out of which 37.9 % were of good quality, and intrinsic value was determined; 54 % were superiority studies, whereas 46 % were non-inferiority or equivalence studies; 32 % of the antibiotics were classified without intrinsic value and nearly 50 % were inconclusive. Conclusion: An elevated proportion of antibiotics of the NEML had uncertain or no intrinsic value, which favors their inappropriate use, bacterial resistance and puts the population at risk.

RESUMO

Background: Mortality in Mexico has decreased substantially in the last years; however, there are segments of the population that experience social deprivation. Objective: To identify and describe at the national level the causes of death by degree of social deprivation (DSD), age and sex. Methods: We analyzed variables from the Censo de Vivienda y Población (Census of Population and Housing) and data from statistics of mortality and DSD, all information corresponding to 2010. Demographic and socioeconomic variables were age, sex, marital status, healthcare provider and locality. Variables related to mortality were main cause of death, year, age and the city of residence of the deceased; we analyzed the DSD at a precinct level. We applied techniques of population analysis and we used statistical packages STATA© and SPSS©. We analyzed information from 1,197,496 adults ≥ 60 years old who represented 10,602,181 elderly. Results: Main causes of death in the very high DSD were heart diseases, neoplasms, malnutrition and anemia, diabetes mellitus (DM) and "lack of an accurate diagnosis related to the type of care received"; in the other DSDs main causes were heart diseases, DM, neoplasms, chronic obstructive pulmonary disease and cerebral vascular disease or liver diseases. Conclusion: We detected several mortality profiles; it is suggested the planning of specific actions.

Introducción: la mortalidad en México ha disminuido de manera importante en los últimos años; sin embargo, existen grupos poblacionales rezagados. Objetivo: determinar y describir a nivel nacional las principales causas de muerte en adultos mayores por grado de rezago social (GRS), edad y sexo. Métodos: se analizaron variables del Censo de Población y Vivienda, de las estadísticas de mortalidad y GRS del año 2010; las variables demográficas y socioeconómicas fueron edad, sexo, estado civil, derechohabiencia y localidad; las relacionadas con mortalidad fueron causa principal de muerte, año de defunción, edad y municipio de residencia del fallecido; el GRS que se analizó fue a nivel municipal. Se aplicaron técnicas para análisis de poblaciones y se utilizaron los paquetes estadísticos STATA© y SPSS©. Se analizó información de 1 197 496 adultos de ≥ 60 años que representaron a 10 602 181. Resultados: las principales causas de muerte en el GRS muy alto fueron enfermedades del corazón, neoplasias, desnutrición y anemia, diabetes mellitus (DM) y "falta de un diagnóstico preciso relacionado con el tipo de atención recibida"; en los otros GRS las causas fueron enfermedades del corazón, DM, neoplasias, enfermedad pulmonar obstructiva crónica y enfermedad vascular cerebral o enfermedades hepáticas. Conclusión: se detectaron varios perfiles de mortalidad; se sugiere la planeación de acciones específicas.

The perceptions of barriers take into consideration the challenges of getting around and using transportation outside the home environment. The covariates consisted of sociodemographic, health-related and disability-related factors. Multivariate logistic regression was used. RESULTS: The perception of environmental barriers outside the home environment was associated with being a woman, living in an urban area, speaking an indigenous language, experiencing emotional symptoms, having walking/movement, visual or self-care disabilities, having severe/extreme disability, having disability caused by illness, using physical devices, and receiving assistance and care in the home environment. CONCLUSIONS: This information is valuable for the design of public policies and programs that promote the participation of individuals with permanent disabilities, a high-priority issue in low- and middle-income countries.

RESUMO

PURPOSE: To analyze potentially inappropriate prescribing (PIP), its prevalence and patient conditions associated with this phenomenon, in a cohort of older adults receiving outpatient care in Mexico. METHODS: Data from 1252 adults ≥ 60 years of age, from primary care centers were analyzed. Information included sociodemographic data, medications, chronic diseases, polypharmacy (≥ 5 medications), functional dependence, cognitive impairment and frailty. Three logistic regression models were employed to identify associations between PIP (according to the Beers criteria) and different variable combinations. RESULTS: A total of 41.8% of participants had at least one PIP. The most frequently identified PIPs involved nonsteroidal anti-inflammatory drugs (NSAIDs) and glibenclamide; clonazepam in patients with cognitive impairment; and interactions of warfarin with NSAIDs. In the multivariate analyses, Model 1 showed that frailty and polypharmacy were associated with PIP. In Model 2, only polypharmacy was associated with PIP. For Model 3, lower educational levels, taking hypoglycemics, nervous system disease drugs, antiasthmatics, gastrointestinal disease drugs and anti-inflammatories-antirheumatics and analgesics, were associated with PIP. CONCLUSION: PIP is common in outpatient treatment of health care services in Mexico. Its association with medical and nonmedical factors highlights the need to improve drug treatment quality focused on implementation of effective strategies, such as educative interventions, electronic medication safety alerts, and inclusion of pharmacists in the health team.

RESUMO

Background: Prescribing errors are a risk factor for patients to present adverse events and a strategy that has been incorporated into medical care to reduce them is the use of computer tools. The objective was to obtain the scientific basis for the development of prescribing error alerts for four chronic diseases with a higher prevalence in population ≥ 65 years. Methods: We reviewed the literature from 2010 to 2015 to obtain information about adverse events and adverse drug reactions associated with the use of drugs for the treatment of diabetes mellitus type 2 (DM2), hypertension, osteoarticular diseases (OD) and depression; the review included these databases: PubMed, OVID, Cochrane Library, LILACS, MEDES, Portal Mayores and SIETES. A group of physicians reviewed and analyzed the papers that were identified and in a meeting they developed the alerts for the treatments used in the included diseases. Results: We obtained 76 papers, out of which 47 were analyzed by the group of physicians, who eliminated 18. With the remaining 29 were integrated 55 alerts: five for DM2, 16 for hypertension, 15 for OD and 19 for depression. Conclusion: The safety alerts that were developed mainly were drug-drug interactions and adverse reactions.

Introducción: los errores de prescripción son un factor de riesgo para que los pacientes presenten eventos adversos; una estrategia que se ha incorporado a la atención médica para disminuirlos es el uso de herramientas informáticas. El objetivo fue obtener el fundamento científico que sustente la elaboración de alertas de errores de prescripción para cuatro padecimientos de mayor prevalencia en población ≥ 65 años. Métodos: se revisó la literatura del 2010 al 2015 para obtener información de eventos adversos o reacciones ligadas al uso de fármacos empleados en diabetes mellitus (DM), hipertensión arterial sistémica (HAS), enfermedad osteoarticular (EO) y depresión; la revisión incluyó las bases de datos PubMed, OVID, Cochrane Library, LILACS, MEDES, Portal Mayores y SIETES. Se integró un grupo de médicos que analizaron los artículos y elaboraron las alertas de los medicamentos involucrados en los tratamientos de las enfermedades incluidas. Resultados: se obtuvieron 76 artículos in extenso, de los cuales 47 fueron analizados por el grupo de médicos, quienes eliminaron 18 artículos. De los 29 restantes, se integraron 55 alertas: 5 de DM, 16 de HAS, 15 de EO y 19 de depresión. Conclusión: las alertas principalmente fueron interacciones fármaco-fármaco confirmadas y reacciones adversas.
