Intrauterine exposure to omeprazole increases the risk of teeth morphological anomalies in the offspring of a murine model.

Conditions experienced in early life have long-lasting effects on offspring health. Despite this, little is known about how maternal exposure to drugs during pregnancy affects offspring teeth morphogenesis. In humans, omeprazole is a common drug used to mitigate Gastroesophageal Reflux Disease. Importantly, omeprazole is a non-specific proton-pump inhibitor, which may inhibit the proton pumps expressed in the developing tooth germ. To date, however, the effects of intrauterine life exposure to omeprazole on offspring tooth development remain unknown. In this study, we addressed this gap in a murine model. Pregnant female Swiss mice were exposed to daily doses of 40 mg/kg of omeprazole from the 5th to the 17th day of pregnancy and the effects of such exposure on offspring odontogenesis parameters such as morphological abnormalities, disruptions in the ameloblast and odontoblast layers and the presence of dentin matrix were measured. Omeprazole exposure significantly increased the prevalence (control: 21.6%; treatment: 60%; p = 0.001) and the risk (posterior mean and 95% credible interval; control: 0.230 [0.129; 0.347]; treatment: 0.593 [0.449; 0.730]) of offspring teeth morphological abnormalities, although there were no statistically significant effects of omeprazole exposure on other parameters of tooth development. These findings suggest that there are potential side-effects to offspring oral health of omeprazole use during pregnancy.

Validation of an educational technology for capecitabine-induced hand-foot syndrome / Validación de tecnología educativa para el síndrome mano-pie inducido por capecitabina / Validação de tecnologia educacional para síndrome mão-pé induzida por capecitabina

ABSTRACT Objective: to validate an educational folder on guidance, prevention and treatment of capecitabine-induced hand-foot syndrome (HFS) using validation from professional specialists in the area. Method: this is a methodological study that analyzed the validity of the folder, characterized as an educational technology. The elaboration and validation process of the content occurred between June and December 2022 in an Oncology Outpatient Unit of a Tertiary Hospital in the interior of São Paulo State, Brazil. The construction and validation phases of the folder contents were subsequently conducted with professional specialists. The validation criteria are based on a Content Validity Index greater than or equal to 0.90. Results: seven oncology specialists, including five nurses and two pharmacists, were invited to participate in the study. Two validation rounds were conducted, and the folder was validated in the second round, achieving an overall content validation index of 1.0. Conclusion: the educational folder was validated by specialists and demonstrated to be a tool with great potential to assist in the prevention and treatment of patients presenting capecitabine-induced hand-foot syndrome.

RESUMEN Objetivo: Validar una carpeta educativa sobre pautas, prevención y tratamiento del síndrome mano-pie inducido por capecitabina, utilizando la validación de profesionales especialistas en la materia. Método: Estudio metodológico que analizó la validez de la carpeta antes mencionada, caracterizada como una tecnología educativa. El proceso de desarrollo y validación del contenido tuvo lugar entre junio y diciembre de 2022 en un Ambulatorio de Oncología de un Hospital Terciario del interior de São Paulo. Las fases de construcción y validación de contenido de la carpeta fueron seguidas con profesionales especialistas. Los criterios de validación se basan en un Índice de Validez de Contenido mayor o igual a 0,90. Resultados: Se invitó a participar en el estudio a siete especialistas en oncología, entre ellos cinco enfermeros y dos farmacéuticos. Se realizaron dos rondas de validaciones, en las que la carpeta fue validada en la segunda ronda, alcanzando un índice general de validación de contenido de 1,0. Conclusión: La carpeta educativa fue validada por expertos y demostró ser una herramienta con gran potencial para ayudar en la prevención y tratamiento de pacientes con síndrome mano-pie inducido por capecitabina.
