Propiedades Psicométricas del Test de Empatía Cognitiva y Afectiva (TECA) en Población Mexicana / Psychometric Properties of the Cognitive and Affective Empathy Test in a Mexican Sample

Resumen Introducción: Evaluar la empatía es cada vez más necesario dentro de diferentes áreas de investigación. Objetivo: El presente estudio presenta un análisis de las propiedades psicométricas del cuestionario Test de Empatía Cognitiva y Afectiva (TECA) que evalúa la empatía desde una perspectiva integral; siendo uno de los pocos construidos originalmente en el lenguaje español. Método: Sé evaluó la fiabilidad y validez de constructo en 607 adultos (137 hombres/ 470 mujeres) estudiantes de población mexicana. Resultados: Los resultados muestran una adecuada fiabilidad del instrumento en general (α = .86). Sin embargo, los análisis factoriales exploratorios y confirmatorios sugiere la necesidad de revisar los ítems. Discusión: La incorporación de metodologías robustas que consideran la naturaleza ordinal de las escalas Likert, como el análisis factorial con la incorporación del intercepto aleatorio permiten mejorar el ajuste de los modelos sin alterar la estructura factorial original. Por último, la invariancia métrica no es alcanzada entre la muestra española original y la mexicana. Conclusiones: El TECA se puede aplicar en población mexicana pero se sugiere una revisión en la construcción de los ítems.

Abstract Introduction: Assessing empathy is an increasing necessity within different research areas. Objective: The present study aims to analyse psychometric properties of the Cognitive and Affective Empathy Test (TECA) questionnaire that assesses empathy from a comprehensive perspective; being one of the few originally built in the Spanish language. Method: The reliability and construct validity were evaluated in 607 adults (137 men / 470 women) students from the Mexican population. Results: The results show adequate reliability of the instrument in general (α = .86). However, the exploratory and confirmatory factor analyzes suggest the need to review the items. Discussion: The incorporation of new methodologies such as robust factor analysis for ordinal type data (i.e. like Likert scales), with the incorporation of the random intercept, allows improving the fit of the models without altering the original factorial structure. Finally, metric invariance is not reached between the original Spanish sample and the Mexican one. Conclusions: The TECA can be applied in the Mexican population but a review of the construction of the items is suggested.

Epidemiological characterization of tibial plateau fractures.

BACKGROUND: Tibial plateau fractures are traumatic injuries with severities ranging from nondisplaced to complicated fractures. This study describes the epidemiological characteristics of patients with tibial plateau fractures treated in five trauma clinics. METHODS: This retrospective, cross-sectional study included 1165 patients with tibial plateau fractures treated between December 2015 and May 2017. Subjects were selected from the medical records of five institutions based on the inclusion and exclusion criteria. Age, sex, laterality, fracture type, trauma mechanism, vehicle type, classification, and associated injuries were assessed via univariate and bivariate analyses. RESULTS: In total, 23.3% of patients with tibial fractures treated during the study period had tibial plateau fractures. Of those affected, 73% were men and 50% were younger than 40 years. Furthermore, 95.7% of fractures were caused by traffic accidents, 82.6% of which involved motorcycles. Fractures were closed in 93.1% of cases, and 78% of subjects had associated injuries. The most common fractures, according to Schatzker classification, were type VI (23%) and V (19.1%) fractures. CONCLUSIONS: Tibial plateau fractures are frequent injuries in our setting and mostly occur in men in their 30 s and 40 s. These fractures are typically caused by motorcycle traffic accidents. LEVEL OF EVIDENCE: IV.

Perioperative outcomes of open vs. robotic radical cystectomy: a nationwide comparative analysis (2008-2014).

INTRODUCTION: Radical cystectomy (RC) is a complex procedure with high perioperative morbidity. In an effort to reduce complications, robotic-assisted RC (RARC) has been adopted as a minimally invasive alternative to the open approach (ORC). Herein, we examine post-operative outcomes of the two surgical approaches in the United States (US) using a large all-payer database. MATERIAL AND METHODS: Using International Classification of Disease, ninth revision (ICD-9) codes, patient who underwent RC were captured from National Inpatient Sample (2008-2014). ICD-9 diagnosis and procedure codes were used to identify post-operative complications. Trends in the utilization of RARC were analyzed. Logistic and log-linear regression accounting for hospital sample weights and sampling years were performed to analyze outcomes after adjustment of pertinent covariates. RESULTS: Of 11,189 patients, 14% underwent RARC. RARC was performed in more teaching hospitals, male patients, those with private insurance, and lower comorbidity score. Performance of RARC steadily increased over the study period (p <0.01). In the last year of the study, 22.8% of cases performed robotically. The weighted average length-of-stay were 10.4 and 8.79 days for ORC and RARC, respectively (p <0.01). In multivariable analyses, RARC was associated with decreased blood transfusion, parenteral nutrition, pneumonia, surgical-site infection, wound and respiratory complications (all, p <0.05). No significant differences were found for in-hospital mortality, cardiac, genitourinary, and vascular complications. CONCLUSIONS: Performance of RARC has significantly increased in recent years. RARC appears safe and feasible for select patients. Earlier discharge and lower complications were noted for those undergoing RARC across different hospital systems nationwide.

Racial/ethnic disparities in renal cell carcinoma: Increased risk of early-onset and variation in histologic subtypes.

BACKGROUND: Racial/ethnic minority groups have a higher burden of renal cell carcinoma (RCC), but RCC among Hispanic Americans (HAs) and American Indians and Alaska Natives (AIs/ANs) are clinically not well characterized. We explored variations in age at diagnosis and frequencies of RCC histologic subtypes across racial/ethnic groups and Hispanic subgroups using National Cancer Database (NCDB) and Arizona Cancer Registry Data. METHODS: Adult RCC cases with known race/ethnicity were included. Logistic regression analysis was performed to estimate odds and 95% confidence interval (CI) of early-onset (age at diagnosis <50 years) and diagnosis with clear cell RCC (ccRCC) or papillary RCC. RESULTS: A total of 405 073 RCC cases from NCDB and 9751 cases from ACR were identified and included. In both datasets, patients from racial/ethnic minority groups had a younger age at diagnosis than non-Hispanic White (NHW) patients. In the NCDB, AIs/ANs had twofold increased odds (OR, 2.21; 95% CI, 1.88-2.59) of early-onset RCC compared with NHWs. HAs also had twofold increased odds of early-onset RCC (OR, 2.14; 95% CI, 1.79-2.55) in the ACR. In NCDB, ccRCC was more prevalent in AIs (86.3%) and Mexican Americans (83.5%) than NHWs (72.5%). AIs/ANs had twofold increased odds of diagnosis with ccRCC (OR, 2.18; 95% CI, 1.85-2.58) in the NCDB, but the association was stronger in the ACR (OR, 2.83; 95% CI, 2.08-3.85). Similarly, Mexican Americans had significantly increased odds of diagnosis with ccRCC (OR, 2.00; 95% CI, 1.78-2.23) in the NCDB. CONCLUSIONS: This study reports younger age at diagnosis and higher frequencies of ccRCC histologic subtype in AIs/ANs and Hispanic subgroups. These variations across racial/ethnic groups and Hispanic subgroups may have potential clinical implications.

Urinary Pesticide Levels in Children and Adolescents Residing in Two Agricultural Communities in Mexico.

The use of pesticides in agricultural activities has increased significantly during the last decades. Several studies have reported the health damage that results from exposure to pesticides. In Mexico, hundreds of communities depend economically on agricultural activities. The participation of minors in this type of activity and their exposure to pesticides represents a potential public health problem. A cross-sectional study was conducted, in which urine samples (first-morning urine) were taken from children under 15 years of age in both communities. A total of 281 urine samples obtained in both communities were processed for the determination of pesticides with high-performance liquid chromatography together with tandem mass spectrometry. In 100% of the samples, at least two pesticides of the 17 reported in the total samples were detected. The presence of malathion, metoxuron, and glyphosate was remarkable in more than 70% of the cases. Substantial differences were detected regarding the other compounds. It is necessary to carry out long-term studies to determine the damage to health resulting from this constant exposure and to inform the health authorities about the problem in order to implement preventive measures.

Important surgical concepts and techniques in inguinal lymph node dissection.

PURPOSE OF REVIEW: Penile cancer is a rare disease with significant physical and psychosocial morbidity. It has a propensity to spread to the inguinal lymph nodes where it can progress to the pelvis and beyond. Here, we present a contemporary review on the surgical management of the lymph nodes. RECENT FINDINGS: Appropriate management of the lymph nodes is critical, and has been shown to impact survival for these patients. Those with lower stage disease can achieve cure with inguinal lymph node dissection (ILND), whereas a multidisciplinary approach is required in those with more extensive disease. Tertiary referral center should be strongly considered. Advances in surgical techniques have allowed for improved outcomes and lower morbidity postoperatively. Modified ILND can be safely performed for those with nonpalpable nodes, whereas diagnostic sentinel node biopsy is a good alternative in centers of experience. Minimally invasive ILND has recently gained popularity with favorable results at short-term follow-up. For those with more advanced disease, the literature remains scarce with no high-level evidence as of yet. SUMMARY: Early upfront surgery appears the best way to approach men with early involvement of the inguinal lymph nodes, whereas systemic therapy is typically reserved for higher volume disease. Clinical trial enrollment continues to be a priority to garner more evidence-based recommendations for this aggressive malignancy.

Racial and Ethnic Disparities in Renal Cell Carcinoma: An Analysis of Clinical Characteristics.

BACKGROUND: Racial/ethnic minority groups, including Hispanic Americans (HAs) and Native Americans (NAs), have a heavier burden of kidney cancer than European Americans (EAs). We investigated variations in clinical characteristics of HA and NA patients with renal cell carcinoma (RCC) who were previously underrepresented. MATERIALS AND METHODS: Clinical records of 294 patients with RCC (151 EAs, 95 HAs, 22 NAs, and 26 others) without prior diagnosis of cancer were reviewed. Logistic regression analysis was performed to understand patients' clinical characteristics. RESULTS: HAs had about 5 years younger average age at diagnosis than EAs (55.8 vs. 60.5 years) and an almost 3-fold increased odds of diagnosis before age 50 years (odds ratio [OR], 2.77; 95% confidence interval [CI], 1.39-5.54). The mean age of diagnosis among NAs was 49.7 years, and NAs had an over 6-fold higher odds of diagnosis at a younger age (OR, 6.23; 95% CI, 2.00-19.46). Clear-cell RCC (ccRCC) was more common in HAs and NAs than EAs. Over 90% of HA patients had ccRCC, whereas only 78.8% of EA patients had ccRCC. HAs had increased odds of diagnosis with ccRCC compared with EAs (OR, 2.79; 95% CI, 1.15-6.80). Among HAs, older patients and patients who spoke Spanish as their primary language were more likely to have advanced stage RCC at diagnosis (OR, 10.48; 95% CI, 1.69-64.89 and OR, 4.61; 95% CI, 1.38-15.40). CONCLUSION: HA and NA patients with RCC had different clinical characteristics than EA patients. It is necessary to better understand the clinical characteristics of these underserved HA and NA populations with high kidney cancer burden.

Effect of symbiotic supplementation on fecal calprotectin levels and lactic acid bacteria, Bifidobacteria, Escherichia coli and Salmonella DNA in patients with cervical cancer.

BACKGROUND: patients with cervical cancer (CC) receiving chemotherapy and radiotherapy have several gastrointestinal adverse effects. OBJECTIVE: to evaluate the effect of dietary symbiotic supplementation on fecal calprotectin (FCP), bacterial DNA levels, and gastrointestinal adverse effects in patients with CC. METHODS: clinical, controlled, randomized, double-blind trial. Patients consumed symbiotics or placebo three times a day for seven weeks. FCP was assessed by Elisa method. DNA from probiotic and pathogenic bacteria were determined by quantitative real-time polymerase chain reaction. Diarrheal evacuations were evaluated with the Bristol stool form scale and nausea and vomiting were measured using the scale of the National Institute of Cancerology of the United States. RESULTS: after a seven-week treatment, FCP concentration was lower in the symbiotic group compared to the control group (p < 0.001). Stool consistency in the placebo and symbiotic groups was similar at baseline. A significant improvement in stool consistency was obtained in both groups at the end of the intervention (p < 0.001). The concentrations and total proportions of the probiotic and pathogenic bacteria were similar in both groups. Nausea significantly diminished in both groups (p < 0.001) at the end of the trial. Furthermore, the symbiotic group had a statistically significant decrease in the frequency and intensity of vomiting when compared to the control group (p < 0.001). CONCLUSIONS: the symbiotic treatment decreases significantly the FCP levels and the frequency and intensity of vomiting in patients with CC.

Introducción: los pacientes con cáncer cervical (CC) tratados con quimioterapia y radioterapia tienen frecuentemente efectos gastrointestinales adversos (EGA). Objetivo: evaluar el efecto de la suplementación dietética con simbióticos en la calprotectina fecal (FCP), el DNA bacteriano y sobre los EGA en pacientes con CC. Métodos: se realizó un ensayo clínico, aleatorizado y doble ciego. Los pacientes ingirieron simbióticos o placebo tres veces al día durante siete semanas. La FCP se evaluó mediante el método de ELISA. El ADN bacteriano se cuantificó mediante PCR en tiempo real. Las evacuaciones se evaluaron con la escala de Bristol y las náuseas y los vómitos se cuantificaron utilizando la escala del Instituto Nacional de Cancerología (USA). Resultados: después de siete semanas de tratamiento, la concentración de FCP fue menor en el grupo tratado con simbióticos en comparación al grupo control (p < 0,001). La consistencia de las heces en los grupos tratados con placebo y simbióticos fue similar al inicio del estudio. Se obtuvo una mejora significativa en la consistencia de las heces en ambos grupos al final de la intervención (p < 0,001). Los niveles de las bacterias probióticas y patogénicas fueron similares en ambos grupos. Los casos de náuseas disminuyeron en ambos grupos (p < 0,001) y el grupo tratado con simbióticos tuvo una disminución significativa en la frecuencia e intensidad de los vómitos en comparación al grupo control (p < 0,001). Conclusiones: el tratamiento simbiótico disminuye significativamente los niveles de FCP y la frecuencia e intensidad del vómito en pacientes con CC

[Mortalidad por enfermedad de Alzheimer en México de 1980 a 2014].

BACKGROUND: Dementias are rarely considered to be a main cause of death; therefore there are only few studies on Alzheimer's mortality covering long periods. OBJECTIVE: To describe mortality from Alzheimer's disease in México for the period from 1980 to 2014. METHOD: Cross-sectional study where, with official mortality data in Mexico according to codes 331.0 and G30, respectively, of the 9th and 10th revisions of the International Statistical Classification of Diseases and Related Health Problems, crude and standardized Alzheimer's disease mortality rates were obtained, both nationally and by states. RESULTS: From almost being inexistent, deaths from Alzheimer's disease went to a rate of 65.12 per 1000 females and 43.66 per 1000 males in the 2010-2014 five-year period. Throughout the study period, the age group with highest mortality rates for this cause were those older than 80 years, with 0.29 per 100,000 population in 1980-1984 and 55.02 in 100,000 in the 2010-2014 period. The region with the highest mortality was the northwest, with rates higher than 2.28 per 100,000 population. CONCLUSIONS: Mortality from Alzheimer's disease is a public health problem in Mexico with a growing trend, especially among women and older adults. Early diagnostic measures and opportune treatment are required in primary care in order to reduce this problem.

INTRODUCCIÓN: Raramente se considera a las demencias como causa principal de muerte, por consiguiente existen pocos estudios sobre la mortalidad por Alzheimer a través de largos periodos. OBJETIVO: Describir la mortalidad por enfermedad de Alzheimer en México durante el periodo 1980-2014. MÉTODO: Estudio transversal en el que, con datos oficiales de mortalidad en México según los códigos 331.0 y G30 de la novena y décima revisiones de la Clasificación Estadística Internacional de Enfermedades y Problemas Relacionados con la Salud, se obtuvieron tasas crudas y estandarizadas de mortalidad por enfermedad de Alzheimer, nacional y por entidad federativa. RESULTADOS: De ser casi inexistentes, en el quinquenio 2010-2014 se registraron tasas de 65.12 y 43.66 muertes por enfermedad de Alzheimer por cada 1000 mujeres y 1000 hombres, respectivamente. En todo el periodo estudiado, el grupo etario con las mayores tasas de mortalidad por esta causa fue el de mayores de 80 años, con 0.29 en 100 000 habitantes durante 1980-1984 y 55.02 durante 2010-2014. La región con mayor mortalidad fue la noroeste, con tasas mayores a 2.28 en 100 000 habitantes. CONCLUSIONES: La mortalidad por enfermedad de Alzheimer es un problema de salud pública en México con tendencia creciente, especialmente entre mujeres y adultos mayores. Se requieren medidas diagnósticas precoces y tratamiento oportuno en primer nivel para aminorar este problema.

Prescripción inadecuada de medicamentos: aportaciones de los paradigmas científicos a su conocimiento / Inadequate drugs prescription: contributions of scientific paradigms to your knowledge

Resumen Se realizó una revisión narrativa con análisis temático sobre las aportaciones de los paradigmas científicos al conocimiento de la prescripción inadecuada de medicamentos. Se buscaron artículos de acceso abierto indexados en PubMed© entre 2010-2014, y se sistematizó información sobre el paradigma, tipo de publicación, perspectiva teórica, objetivo, método y resultados. De los 992 artículos encontrados, se seleccionaron 118, y se tomó una muestra propositiva de 15, según su diseño, representando los cuatro paradigmas. Los artículos positivistas reportaron prevalencia, factores asociados, efectividad de intervenciones y criterios de evaluación; los interpretativos explicaron las causas del problema según los involucrados; los críticos denunciaron la influencia de la industria farmacéutica; y el participativo abordó el problema secundariamente y lo solucionó en un escenario para una enfermedad y grupo farmacológico específicos. Se concluyó que la prescripción inadecuada de medicamentos como problema de investigación en salud pública recibe aportes de los cuatro paradigmas, con dominio del positivismo, lo que se atribuye al carácter paradigmático de la ciencia desde la que se le aborda habitualmente, y que una perspectiva multi-paradigmática es el mejor abordaje.

Abstract This study conducted a narrative review with thematic analysis about contributions of scientific paradigms to knowledge of inadequate drugs prescription. We searched open access articles indexed in PubMed© between 2010 and 2014, and we systematized information about scientific paradigm, publication type, theoretical perspective, objective, method and results. From the 992 articles found, 118 were selected. From those, we chose a purposive sample of 15, according to the design of the studies, representing the four paradigms. The positivists articles reported prevalence, associated factors, effectiveness of interventions and evaluation criteria; the interpretive explained the causes of the problem according to those involved; the critics denounced the influence of pharmaceutical industry; and the participative addressed the problem secondarily and solved it in a scenario for a specific disease and pharmacological. We concluded that the inadequate drugs prescription as research problem in public health had contributions from the four paradigms, with dominance of positivism, which is attributed to the paradigmatic perspective of the science, from which it is usually studied, and that a multi-paradigmatic perspective is the best approach to the public health issue.

Effect of fish and olive oil on mitochondrial ATPase activity and membrane fluidity in patients with relapsing-remitting multiple sclerosis treated with interferon beta 1-b.

BACKGROUND: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system associated with increased oxidative stress (OS) and mitochondrial alterations. Fish oil consumption has neuroprotective, antioxidant and anti-inflammatory effects in patients with relapsing-recurrent MS (RR-MS). OBJECTIVE: To evaluate changes in the hydrolytic activity of ATP synthase and mitochondrial membrane fluidity in patients with RR-MS who receive fish oil or olive oil as a dietary supplement. METHODS: Clinical, controlled, randomized, double-blind trial. Patients consumed fish oil or olive oil for one year. The hydrolytic activity of ATPase and the fluidity of the mitochondrial membrane of platelets were quantified. RESULTS: In patients with RR-MS, a decrease in the fluidity of mitochondrial membranes and an increase in the hydrolytic activity of ATP synthase was observed in comparison with healthy controls. After 6 or 9 months of treatment with fish oil or olive oil, respectively, these values were normalized. CONCLUSION: The consumption of fish oil and olive oil increases the fluidity of the mitochondrial membranes and decreases the catabolic activity of ATP synthase in platelets from patients with RR-MS.

For the Guatemalan physicians'14% was high, average 63%, and 23% defined by random. There were no statistically significant differences between healthcare country units, but between the medium of Mexicans (0.55) and Guatemalans (0.55) (p = 0.02). CONCLUSION: The proportion of the high clinical competency of Mexican physicians' was as Guatemalans.

Prevalence of Albuminuria in Children Living in a Rural Agricultural and Fishing Subsistence Community in Lake Chapala, Mexico.

The occurrence of Chronic Kidney Disease (CKD) of unknown etiology in autochthonous child populations residing along the Lake Chapala lakeshore is endemic (Jalisco, México). The objective of this study was to determine the prevalence of albuminuria in the pediatric population and to measure the glomerular filtration rate in children with two positive albuminuria tests. Urinary albumin was measured in 394 children. Subjects with two or more positive albuminuria test donated blood samples for the determination of serum biomarkers. From a rural community with 565 children under the age of 17 years, 394 (69.7%) participated with first morning urine samples. A total of 180 children were positive (with two or more positive albuminuria tests). The prevalence of albuminuria among the children participating in the study was 45.7%. Of the 180 children with persistent albuminuria, 160 (88.9%) were tested for serum creatinine, urea, and cystatin C. The 68.1% of the children studied, were found in stages 3a and 3b of the Kidney Disease Improving Global Outcomes (KDIGO) classification (mean glomerular filtration rate (GFR) 51.9 and 38.4 mL/min/1.73 m² respectively). The lowest frequencies were for classifications 1 and 4. None of the subjects was classified as grade 5. The prevalence of albuminuria in children from this rural community is 3-5 times higher than reported in international literature. Regarding GFR, more than 50% of children studied are under 60 mL/min/1.73 m². It is a priority to find the causes of albuminuria and CKD in this Mexican region.
