Deficiencia e insuficiencia de vitamina D en mujeres post cirugía bariátrica Roux en Y / Vitamin D deficiency and insufficiency among women with Roux-en-Y bariatric surgery / Deficiência e Insuficiência de vitamina D em mulheres post cirurgia bariátrica Roux em Y

Objetivo Determinar la relación entre la falta de seguimiento, adherencia al tratamiento con multivitamínicos y niveles séricos de 25-OH vitamina D (Vit-D) en mujeres post-cirugía BPRY, en la UNEME de la ciudad de Tijuana, Baja California, México. Métodos Estudio Transversal analítico que incluyó mujeres post-cirugía BPRY (GCa, n=13), con Obesidad Mórbida (GOM, n=13) y mujeres aparentemente sanas (GCo, n=13). Posterior a la autorización mediante consentimiento informado escrito, se realizó una historia clínica, valoración antropométrica, aplicación del instrumento de medición y en una segunda cita se tomó una muestra sanguínea para la cuantificación de Vit-D. El instrumento de medición fue validado mediante Kappa de Cohen mayor al 80% y alfa de Cronbach de 1. El análisis estadístico de los datos se realizó mediante pruebas de diferencia de medias t de Student y ANOVA donde se consideró una p < 0.05 en una prueba a dos colas. Se determinó prevalencia, significancia estadística de la falta de adherencia y seguimiento en relación a los niveles de Vit-D. Resultados La prevalencia de falta de adherencia al tratamiento multivitamínico en estas mujeres con post-cirugía BPRY fue de 85% y la falta de seguimiento post quirúrgico que incluye pruebas de laboratorio de micronutrientes fue del 100%. Se encontró una diferencia estadísticamente significativa entre las medias de los niveles de Vit-D entre las mujeres con y sin adherencia al multivitamínico p < 0.05, IC 95%. Conclusiones Se demostró que la falta de adherencia y seguimiento al tratamiento con multivitamínicos son factores de riesgo para la insuficiencia y deficiencia de Vit-D en pacientes con post-cirugía BPRY.

Objective To determine the interrelationships among lack of compliance, multi-vitamin treatment adherence, and serum levels of 25-OH vitamin D among women with Roux-en-Y bariatric surgery in the UNEME of Tijuana, Baja California, Mexico. Methods This is an analytical and transversal study on women with Roux-en-Y bariatric surgery (GCa, n=13) with morbid obesity (GOM, n=13), and apparently healthy women (GCo, n=13). After the corresponding written informed consents, in a first appointment, the medical record, the anthropometric assessment, and the administration of the instrument were performed, while in a second appointment, blood samples were taken in order to measure the vitamin D levels. The assessment instrument was validated through a Cohen Kappa greater than 80% and a Cronbach Alpha of 1. Student's t test and two-tailed, p < 0.05 ANOVAS were calculated. Results While a lack of adherence to multi-vitamin treatment was found in 85% of the women, a lack of post-surgical follow-up, including micro-nutrients lab tests, was found in 100%. A statistically significant difference between the mean vitamin D levels of women with and without multi-vitamin treatment adherence was found (p < 0.05, CI 95%). Conclusions It was demonstrated that the lack of adherence to multi-vitamin treatments is a vitamin D deficiency risk factor among patients with Roux-en-Y bariatric surgery.

Determinou-se prevalência, significância estatística da falta de aderência e seguimento em relação aos níveis de Vit-D. Resultados A falta de aderência ao tratamento multivitamínico nestas mulheres bariátricas foi de 85% e a falta de seguimento post cirúrgico que inclui testes de laboratório de micronutrientes foi de 100%. Encontrou-se uma diferença estatisticamente significativa entre a média dos níveis de Vit-D entre as mulheres com e sem aderência no multivitamínico p < 0.05, IC 95%. Conclusões . Demostrou-se que a falta de aderência e seguimento no tratamento com multivitamínicos são fatores de risco para a insuficiência e deficiência de Vit-D em pacientes bariátricos.

[Perforated peptic ulcer: is the form of methamphetamine known as "crystal meth" a new risk factor?]. / Úlcera péptica perforada: ¿es la forma de la metanfetamina conocida como "cristal" un nuevo factor de riesgo?

BACKGROUND: The emergence of new synthetic drugs related to peptic ulcer perforation has been reported. Recently an increase in the use of inhaled methamphetamine has been observed and we have described an association of frequent use with peptic disease symptomatology and perforation. AIMS: To determine whether methamphetamine use is a factor related to peptic acid disease and perforation and to establish its demographic variables. MATERIAL AND METHODS: A retrospective, comparative, descriptive, and observational study was carried out through the evaluation of medical records of patients admitted to the Surgery Service with perforated ulcer, within the time frame of January 2002 to March 2005. A descriptive analysis was carried out, along with the Z test, odds ratio, confidence interval, p value and the Student's t test. RESULTS: Forty-two patients were divided into 2 groups: methamphetamine users (n=25) and nonusers (n=17). There was a statistically significant difference in relation to age, which was lower in the methamphetamine user group (38,7 years vs 58,88 years, p=0.0001). In addition, there was a trend in the user group to develop peptic ulcer perforation at earlier ages compared with the nonuser group (p=0.0001). There were no statistically significant differences between the two groups in regard to clinical presentation. CONCLUSIONS: Methamphetamine use is related to ulcer perforation in age groups of younger patients when compared with nonuser patients.
