Resilience: A Protective Factor from Depression and Anxiety in Mexican Dialysis Patients.

Depression and anxiety are highly prevalent psychological disorders in end-stage renal disease (ESRD) that have a negative clinical impact. The purpose of our study was to identify factors associated with the presence of depression and anxiety, in a sample of ESRD patients treated with hemodialysis. We included 187 patients from two dialysis facilities, age 18-65 years. Beck's depression and anxiety inventories, KDQOL36 questionnaire, the cognitive distortion scale and the Mexican scale of resilience were used. Socio-demographic and clinical information was obtained from medical records. Depression was present in 143 (76.4%) patients. Patient with depression were older (33 (26-52) years vs. 30 (24.43) years, p = 0.025), had a lower education level (36% vs. 9%, p = 0.001), used more medications (67% vs. 36%, p = 0.001), had a comorbidity (75% vs. 41%, p = 0.001), and a higher proportion were waiting for a kidney transplant. Anxiety was present in 112 (59.8%) cases. By multivariate analysis, depression was independently associated with lower education, absence of previous kidney transplant, anxiety, higher cognitive distortion, lower psychological resilience, and lower quality of life scores. In conclusion, lower psychological resilience, lower education level, and higher cognitive distortions are factors associated with depression and anxiety in ESRD patients.

Causal analysis of fetal death in high-risk pregnancies.

OBJECTIVES: To determine the causes of fetal death among the stillbirths using two classification systems from 22 weeks of gestation in a period of three years in high-risk pregnancies. This is a retrospective observational study. METHODS: The National Institute of Perinatal Health in Mexico City is a Level 3 care referral center attending high-risk pregnancies from throughout the country. The population consisted of patients with fetal death during a three-year period. Between January 2016 and December 2018, all stillbirths were examined in the Pathology Department by a pathologist and a medical geneticist. Stillbirth was defined as a fetal death occurring after 22 weeks of gestation. RESULTS: Main outcome measures: Causal analysis of fetal death using the International Statistical Classification of Disease and Related Health Problems-Perinatal Mortality (ICD-PM) and initial causes of fetal death (INCODE) classification systems. A total of 297 stillborn neonates were studied. The distribution of gestational age in antepartum stillbirths (55.2%) showed a bimodal curve, 36% occurred between 24 and 27 weeks and 32% between 32 and 36 weeks. In comparison, the majority (86%) of intrapartum deaths (44.8%) were less than 28 weeks of gestation. Of the 273 women enrolled, 93 (34%) consented to a complete fetal autopsy. The INCODE system showed a present cause in 42%, a possible cause in 54% and a probable cause in 93% of patients. CONCLUSIONS: The principal causes of antepartum death were fetal abnormalities and pathologic placental conditions and the principal causes of intrapartum death were complications of pregnancy which caused a premature labor and infections.

Disease Activity Score on 28 Joints and Polypharmacy Are Independent Predictors for Health-Related Quality of Life Evaluated by INCAVISA in Patients With Rheumatoid Arthritis.

OBJECTIVE: The aim of this study was to investigate the main factors associated to a diminished health-related quality of life (HRQoL) evaluated by INCAVISA (Health-Related Quality of Life Inventory for Latin American Patients) in patients with rheumatoid arthritis (RA). METHODS: Female, 18 years or older, RA (American College of Rheumatology 1987 criteria and American College of Rheumatology/European League against Rheumatism 2010 criteria) patients who attended the outpatient rheumatology department of the Hospital Civil "Dr. Juan I. Menchaca," Guadalajara, Mexico, matched with healthy controls were included. Patients with any known comorbidities or treatment with antidepressive drugs were excluded. Trained physicians performed the RA clinical evaluation and INCAVISA. All data were analyzed using SPSS 21.0 software (SPSS Inc, Chicago, IL); P < 0.05 was considered statistically significant. RESULTS: Patients with polypharmacy (≥3 drugs) had a lower HRQoL by INCAVISA. The number of drugs, total comorbidities, and DAS-28 (Disease Activity Score on 28 Joints) were negatively correlated with total INCAVISA. In multivariate analysis, DAS-28 and polypharmacy were independent predictors for a negative perception of HRQoL evaluated by INCAVISA in RA patients. CONCLUSIONS: Disease activity and disability secondary to RA have a negative impact in the HRQoL. Other factors such as the number of drugs prescribed to these patients have been shown to be important for the negative perception of their HRQoL evaluated by INCAVISA.

Competencia y compartimiento emocional en usuarios de cocaína: Psicometría y relación con variables sociodemográficas y clínicas / Emotional competence and magazine in cocaine users: Psychometrics and relationship with sociodemographic and clinical variables

INTRODUCCIÓN: Existe evidencia de relación entre factores emocionales y el consumo de drogas. Sin embargo, al menos la competencia emocional y el compartimiento social de las emociones en usuarios de cocaína no han sido estudiados con anterioridad, en parte debido a la reciente generación de las herramientas para su medición. OBJETIVO: Evaluar las características psicométricas de la Escala de Alexitimia de Toronto (EAT), el Cuestionario de Competencias Emocionales (CEMO), y el Cuestionario de Creencias sobre los efectos de Compartimiento Social de Emociones (CCSE) en pacientes mexicanos usuarios de cocaína, así como establecer su relación con variables socio-demográficas y clínicas. MÉTODO: Los instrumentos fueron completados junto con las Escalas de Afectividad Positiva (AP) y Negativa (AN) en dos ocasiones por 158 pacientes usuarios de cocaína. RESULTADOS: Las tres escalas mostraron coeficientes alpha superiores a .70. La EAT y el CEMO presentaron alta estabilidad temporal a quince días. La AN se asoció positivamente con la EAT y negativamente con el CEMO. La AP se correlacionó negativamente con la EAT y positivamente con el CEMO y el CCSE. El 50.9% de los pacientes presentaron una dificultad relevante en la identificación y la expresión de sus emociones, que se relacionó de forma negativa con la escolaridad. DISCUSIÓN Y CONCLUSIÓN: Se sugiere necesaria la sistematización de la evaluación y el tratamiento de las dificultades en la expresión emocional de usuarios de cocaína. Las versiones en español de las escalas evaluadas en este estudio resultaron válidas y confiables para su uso clínico y de investigación en pacientes mexicanos usuarios de cocaína.

INTRODUCTION: Current evidence suggests a relationship between emotional factors and drugs consumption, although at least both emotional competence and social magazine of emotions have not been studied in cocaine users, in part due to the recent generation of tools for their measure. OBJECTIVE: To evaluate the psychometric properties of the Toronto Alexithymia Scale (TAS), Emotional Competence Questionnaire (ECQ), and the Questionnaire about Beliefs in the effects of the Social Magazine of Emotions (QSME) in Mexican cocaine users, and to establish its relationship with socio-demographic and clinical variables. METHOD: All instruments, as well as the Positive Affectivity (PA) and Negative Affectivity (NA) Scales, were completed twice by 158 cocaine users. RESULTS: All scales showed alpha coefficients greater than .70. The TAS and ECQ presented high temporal stability. NA was positively associated with TAS, and negatively with ESQ. PA showed a negative correlation with TAS, and a positive relation with ECQ and QSME. 50.9% of the patients had a relevant difficulty in identifying and expressing their emotions, which was negatively correlated with schooling. DISCUSSION AND CONCLUSION: A systematic evaluation and treatment of difficulties in the expression of emotions in cocaine users seems to be necessary. The Spanish versions of the scales are valid and reliable for their use with clinical and research purposes in Mexican cocaine users.

Segmentation of the common carotid artery walls based on a frequency implementation of active contours: segmentation of the common carotid artery walls.

Atherosclerosis is one of the most extended cardiovascular diseases nowadays. Although it may be unnoticed during years, it also may suddenly trigger severe illnesses such as stroke, embolisms or ischemia. Therefore, an early detection of atherosclerosis can prevent adult population from suffering more serious pathologies. The intima-media thickness (IMT) of the common carotid artery (CCA) has been used as an early and reliable indicator of atherosclerosis for years. The IMT is manually computed from ultrasound images, a process that can be repeated as many times as necessary (over different ultrasound images of the same patient), but also prone to errors. With the aim to reduce the inter-observer variability and the subjectivity of the measurement, a fully automatic computer-based method based on ultrasound image processing and a frequency-domain implementation of active contours is proposed. The images used in this work were obtained with the same ultrasound scanner (Philips iU22 Ultrasound System) but with different spatial resolutions. The proposed solution does not extract only the IMT but also the CCA diameter, which is not as relevant as the IMT to predict future atherosclerosis evolution but it is a statistically interesting piece of information for the doctors to determine the cardiovascular risk. The results of the proposed method have been validated by doctors, and these results are visually and numerically satisfactory when considering the medical measurements as ground truth, with a maximum deviation of only 3.4 pixels (0.0248 mm) for IMT.

Combining two teaching techniques for young children on Aedes aegypti control: effects on entomological indices in western Mexico.

A study of the effect of educating four- to six-year-old children in mosquito control was recently conducted in a city in the state of Jalisco, western Mexico. Four neighborhood districts were selected. Children attending one kindergarten in each of two experimental districts were taught mosquito control with a video from the American Mosquito Control Association (AMCA), joined to the use of the AMCA Touch Table Technique. The entomological indices monitored in the study decreased significantly (P<0.05) in houses in the experimental districts, apparently because parents acted on the comments and suggestions of the children and eliminated or monitored containers used as oviposition sites by mosquitoes. Based on these results, combining both techniques for teaching children mosquito control is a potentially useful tool for control efforts in Mexico and other places in Latin America.
