ABSTRACT
Honey has been shown to have antimicrobial activity against different microorganisms, but its effects on oral biofilms are largely unknown. In this review, we analyzed the currently available literature on the antimicrobial activity of honey against oral biofilms in order to determine its potential as a functional food in the treatment and/or prevention of oral diseases. Here, we compare studies reporting on the antimicrobial activity of honey against systemic and oral bacteria, discuss methodological strategies, and point out current gaps in the literature. To date, there are no consistent studies supporting the use of honey as a therapy for oral diseases of bacterial origin, but current evidence in the field is promising. The lack of studies examining the antibiofilm activity of honey against oral microorganisms reveals a need for additional research to better define aspects such as chemical composition, the mechanism(s) of action, and antimicrobial action.
ABSTRACT
Contexto: O tromboembolismo venoso (TEV) representa uma preocupação crescente nas instituições hospitalares, tem grande impacto sobre a morbimortalidade em pacientes clínicos e cirúrgicos, e é a principal causa de morte evitável hospitalar. Embora existam modelos de avaliação de risco para pacientes hospitalizados, a profilaxia ainda é subutilizada ou é feita de forma incorreta. Objetivos: Avaliar o perfil de risco para TEV de pacientes clínicos e cirúrgicos recém-internados, bem como as medidas tromboprofiláticas aplicadas nas primeiras 24 horas de internação. Métodos: Este estudo transversal foi realizado em um hospital geral de grande porte do interior do estado de São Paulo entre março e julho de 2015. Os escores de Pádua e Caprini foram utilizados para estratificação de risco dos pacientes clínicos e cirúrgicos, respectivamente, enquanto a análise das medidas tromboprofiláticas baseou-se nas recomendações do 8º e 9º Consenso do American College of Chest Physicians. Resultados: Foram analisados 592 pacientes (62% clínicos e 38% cirúrgicos). A estratificação de risco revelou necessidade de quimioprofilaxia em 42% dos pacientes clínicos e 81% dos cirúrgicos (51% de alto risco e 30% de moderado risco). Por outro lado, receberam profilaxia adequada nas primeiras 24 horas de internação 54% dos pacientes clínicos de alto risco, 85% dos cirúrgicos de alto risco e 4% dos cirúrgicos de moderado risco, todos sem contraindicação. Conclusões: Há necessidade de aprimoramento da segurança do paciente em relação ao TEV já nas primeiras horas de internação. Existe uma subutilização da quimioprofilaxia especialmente nos pacientes clínicos de alto risco e cirúrgicos de moderado risco
Background: Venous thromboembolism (VTE) is a cause for growing concern in hospitals, has great impact on morbidity and mortality in clinical and surgical patients, and is the leading cause of preventable hospital deaths. Although there are risk assessment models for hospital inpatients, prophylaxis is still underused or is administered incorrectly. Objectives: To assess the risk profile for VTE in recently hospitalized clinical and surgical patients and evaluate the thromboprophylactic measures implemented in the first 24 hours of hospitalization. Methods: Cross-sectional study conducted in a large general hospital in the state of São Paulo, Brazil, between March and July 2015. Padua and Caprini scores were used for risk stratification of clinical and surgical patients, respectively, while thromboprophylactic measures were analyzed for compliance with the recommendations contained in the 8th and 9th Consensus of the American College of Chest Physicians. Results: A total of 592 patients (62% clinical and 38% surgical) were assessed. Risk stratification revealed a need for chemoprophylaxis in 42% of clinical patients and 81% of surgical patients (51% high risk and 30% moderate risk). However, 54% of high-risk clinical patients, 85% of high-risk surgical patients, and 4% of moderate-risk surgical patients, who were free from contraindications, were actually given the correct prophylaxis in the first 24 hours of hospitalization. Conclusions: There is a need to improve patient safety in relation to VTE in the first hours of hospitalization, since there is underutilization of chemoprophylaxis, especially in high-risk clinical patients and moderate-risk surgical patients
