Depression and Medical Treatment Adherence in Mexican Patients With Glaucoma.

PRECIS: The prevalence of depression in Mexican patients with glaucoma is higher than that reported in the general population. Depression prevalence and severity are directly associated with glaucoma severity and lower adherence to medical treatment. PURPOSE: To determine the prevalence of depression in patients with glaucoma and to describe the correlation between the severity of depression, glaucoma, and treatment adherence. PATIENTS AND METHODS: This cross-sectional study included 111 patients with glaucoma who answered the Beck Depression Inventory (BDI)-II and the Morisky-Green questionnaire that evaluated their depression severity and medical treatment adherence. Low treatment adherence was defined as having a score of >2 on the Morisky-Green questionnaire. Analysis of variance, Fisher exact test, and linear regression models were used for statistical analyses. The main outcomes were prevalence of depression, prevalence of depression according to glaucoma damage, and the association between depression severity, medical treatment adherence, and glaucoma damage. RESULTS: The average patient age was 67.6±13.8 years. The prevalence of depression was 50.4%. Analysis of variance revealed a statistically significant association between glaucoma severity of the "worse eye" and the BDI raw score. In the "better eye," there was no statistically significant difference in mean BDI raw scores across glaucoma severity categories. There was a statistically significant association between the presence of depression and the level of treatment adherence after adjusting for age, sex, type of glaucoma, and the glaucoma severity in both eyes. The risk of low treatment adherence in patients with depression was 38 times that of patients with no depression. CONCLUSION: Glaucoma is associated with a prevalence of depression nearly 10 times higher than that in the general population. Glaucoma, depression severity, and lower adherence to medical treatment are associated.

[Myasthenia gravis in adults of institutions pertaining to the Mexican public health system: an analysis of hospital discharges during 2010]. / Miastenia gravis (MG) en adultos de instituciones pertenecientes al sistema público sanitario mexicano: un análisis de egresos hospitalarios durante el año 2010.

INTRODUCTION: Epidemiological studies on myasthenia gravis (MG) in Mexico is mainly derived from experiences in referral centers. OBJECTIVE: To describe the epidemiological characteristics of hospital discharges during 2010 with the diagnosis of MG in adults hospitalized in the Mexican public health system. METHODS: We consulted the database of hospital discharges during 2010 of the National Health Information System (Ministry of Health, IMSS, IMSS oportunidades, ISSSTE, PEMEX, and the Ministry of Defense). The MG records were identified by the code G70.0 of the International Classification of Diseases 10th revision. RESULTS: During 2010 there were 5,314,132 hospital discharges (4,254,312 adults). Among them, 587 (0.01%) were adults with MG (median age: 47 years, 60% women). Women with MG were significantly younger than men (median age: 37 vs. 54 years, respectively; p < 0.001). The median hospital stay was six days. The case fatality rate was 3.4%, without gender differences. Age was associated with the probability of death. CONCLUSIONS: We confirmed the bimodal age-gender distribution in MG. The in-hospital case fatality rate in Mexico is consistent with recent reports around the world.

[Characterisation of factors associated with carotid stenosis in a population at high risk]. / Caracterizacion de factores asociados con estenosis carotidea en una poblacion de alto riesgo.

INTRODUCTION: Moderate to severe stenosis is the less prevalent among the forms of carotid atherosclerotic disease), but it carries a high risk of ischaemic stroke. AIM: To characterise factors associated with moderate to severe carotid stenosis in a high-risk population. PATIENTS AND METHODS: We performed an analysis on traditional risk factors associated with carotid stenosis ≥50% in 533 patients who received Doppler ultrasound due to a history of stroke (34%) or who had = 2 of the risk factors: age ≥55 years (86%), hypertension (65%), dyslipidemia (52%), obesity (42%), diabetes (40%) or smoking (40%). RESULTS: The prevalence of carotid stenosis ≥50% was 7.1%, symptomatic (associated with stroke in congruent territory) in 5.6%, bilateral in 2.1% and bilateral symptomatic in 1.5%. A 36.8% of patients had moderate to severe load (≥4) of atherosclerotic plaques (25.9% moderate: 4-6 plaques, and 10.9% severe: ≥7 plaques). By multivariate analysis we identified the age ≥75 years, dyslipidemia, and smoking as factors independently associated with carotid stenosis ≥50%, and hypertension and smoking with symptomatic stenosis. The number of risk factors was strongly associated with the prevalence of carotid stenosis. Notably, neither diabetes nor obesity explained the degree of moderate to severe carotid stenosis. CONCLUSIONS: As forms of carotid atherosclerotic disease, moderate to severe stenosis is less frequent than a high burden of atherosclerotic plaques. Advanced age, smoking, dyslipidemia and hypertension are the main traditional risk factors associated with the degree of carotid stenosis.

TITLE: Caracterizacion de factores asociados con estenosis carotidea en una poblacion de alto riesgo.Introduccion. La estenosis moderada a grave es la forma de enfermedad carotidea aterosclerosa menos prevalente, pero que implica un alto riesgo de ictus isquemico. Objetivo. Caracterizar los factores asociados con la estenosis carotidea moderada a grave en una poblacion de alto riesgo. Pacientes y metodos. Realizamos un analisis de los factores de riesgo tradicionales asociados a estenosis carotidea >= 50% en 533 pacientes que recibieron evaluacion mediante ultrasonograma Doppler por historia de ictus (34%), o que contaban con al menos dos de los factores de riesgo: edad >= 55 años (86%), hipertension (65%), dislipidemia (52%), obesidad (42%), diabetes (40%) o tabaquismo (40%). Resultados. La prevalencia de estenosis carotidea >= 50% fue del 7,1%, sintomatica (asociada a ictus en territorio congruente) en el 5,6%, bilateral en el 2,1% y sintomatica bilateral en el 1,5%. Un 36,8% de los pacientes presento carga moderada a grave (>= 4) de placas de ateroma (25,9%, moderada: 4-6 placas; y 10,9%, grave: >= 7 placas). Mediante analisis multivariable se identifico la edad >= 75 años, la dislipidemia y el tabaquismo como factores asociados con estenosis >= 50%, y la hipertension arterial y el tabaquismo con estenosis sintomatica. El numero de factores de riesgo se asocio fuertemente con la prevalencia de estenosis carotidea. Notablemente, ni la diabetes ni la obesidad explicaron el grado de estenosis moderada a grave. Conclusiones. Como formas de enfermedad carotidea aterosclerosa, la frecuencia de estenosis moderada a grave es menor que una carga alta de placas de ateroma. La edad avanzada, el tabaquismo, la dislipidemia y la hipertension son los principales factores tradicionales que se asocian con el grado de estenosis carotidea.

Mortalidad asociada al diagnóstico de síndrome de Guillain-Barré en adultos ingresados en instituciones del sistema sanitario mexicano / Mortality associated with a diagnosis of Guillain-Barré syndrome in adults of Mexican health institutions

Introducción. El síndrome de Guillain-Barré (SGB) es una urgencia neurológica que constituye la principal causa de parálisis flácida en el mundo, y que afecta a todos los grupos etarios. Se desconocen notablemente las características epidemiológicas esenciales del SGB en la mayor parte de los países de América Latina. Objetivo. Determinar la mortalidad asociada con el diagnóstico de SGB en altas hospitalarias efectuadas durante el año 2010 en instituciones de la Secretaría de Salud, México. Pacientes y métodos. Se analizó la base de datos de altas hospitalarias de instituciones que pertenecen a la Secretaría de Salud. Se identificaron los casos de SGB mediante el código G61.0 de la Clasificación Internacional de Enfermedades, 10.ª revisión (CIE-10). Se excluyeron los registros de pacientes menores de 18 años y los casos sin información demográfica completa. Resultados. Durante el año 2010 se registraron 2.634.339 altas de hospitales que pertenecen a la Secretaría de Salud. Se identificó un total de 467 hospitalizaciones por SGB en adultos (mediana de edad: 41 años; 62,1% hombres) de 121 instituciones sanitarias de los 32 estados federados de México. Durante el verano y otoño se registró la mayor frecuencia de hospitalizaciones por SGB. La mediana de la estancia hospitalaria fue de 8 días y la tasa de mortalidad hospitalaria, del 10,5%. La probabilidad de muerte se asoció directamente con la edad, sin una tendencia particular respecto al sexo, hospital de atención o entidad federativa. Conclusiones. En 2010, la mortalidad hospitalaria por SGB en esta parte del sistema sanitario mexicano fue más alta de la que se informa en estudios contemporáneos. Se observó una asociación estacional con la frecuencia de hospitalizaciones por SGB (AU)

Introduction. Guillain-Barré syndrome (GBS) is a neurological emergency representing the main cause of flaccid paralysis around the world, affecting all age groups. Little is known about the essential epidemiology of GBS in most Latin American countries. Aim. To determine the mortality associated with the diagnosis of GBS in hospital discharges during 2010 in hospitals of the Ministry of Health, Mexico. Patients and methods. We analyzed the database of hospital discharges of institutions pertaining to the Ministry of Health. Study cases were identified by the code G61.0 of the International Classification of Diseases, 10th revision (ICD-10). We excluded records of patients younger than 18 years and patients without complete demographic information. Results. During the year 2010 there were 2,634,339 discharges from hospitals of the Ministry of Health. We identified a total of 467 hospitalizations due to GBS in adults (median age: 41 years; 62.1% male) from 121 health institutions of the 32 Republic States. The highest frequency of GBS hospitalizations occurred during summer and fall. The median hospital stay was 8 days. The hospital mortality rate was 10.5%. The probability of death was directly associated with age, without a particular trend regarding gender, hospital care or state. Conclusions. In 2010 GBS hospital mortality in this part of the Mexican health system was higher than that reported in contemporary studies. A seasonal association was observed regarding the frequency of hospitalizations for GBS (AU)
