RESUMO
BACKGROUND: There have been many scales to predict pneumonia in stroke patients, but they are so complex, making it difficult to apply in practice. Therefore, we conducted this study to assess the role of the National Institutes of Health Stroke Scale (NIHSS) and the Gugging Swallowing Screen (GUSS) in predicting stroke-associated pneumonia (SAP). These scales are routinely used in stroke patients. Therefore, their application in predicting SAP risk will be of high value in clinical practice. There has been no previous study evaluating the effectiveness of SAP risk prediction for each of these scales. AIM: This study aimed to compare the value of NIHSS and GUSS in SAP prediction and their convenience in clinical practice. METHODS: It was a cohort study. The receiver operating characteristics (ROC) curves were constructed to assess the sensitivity (Se) and specificity (Sp) of the scales. Area under the curves (AUC) were calculated, and we compared them. RESULTS: NIHSS had a medium value of predictor of SAP with AUC 0.764 (95% CI 0.735-0.792), 65.4% Se, 76.5% Sp. GUSS had good value in predicting SAP with AUC 0.858 (95% CI 0.833-0.880), 80.5% Se, 80.1% Sp. Pairwise comparison of ROCs curves demonstrated that the difference between two AUCs was significant (p < 0.01). Performing GUSS required 24.5 ± 6.7 minutes, 2.5 times longer than NIHSS (9.9 ± 2.0 minutes). CONCLUSION: GUSS had a better predictive value of SAP than NIHSS. But NIHSS was more convenient in clinical practice because of its simple instrument and quick performance.
RESUMO
Clostridium difficile infection (CDI) is the most common cause of identifiable diarrhea in hospitalized patients. The incidence and severity of CDIs are increasing. The increased incidence and severity of the disease has sparked interest in the optimal treatment of CDI as well as the use of new therapies and drug discovery. Current treatment strategies are inadequate with decreased response rates to metronidazole, and high recurrence rates with the use of metronidazole and oral vancomycin. Although incidence rates continue to be low, in vitro resistance to antibiotics used for the treatment of CDI has been noted. Recently, important data has emerged on new anti-C. difficile antibiotics such as rifaximin, rifalazil, fidaxomicin, nitazoxanide, tigecycline and ramoplanin. The purpose of this review is to provide an update on the in vitro susceptibility and new antibiotic treatment options for CDI. This review will focus primarily on scientific studies published in the last 36 months in order to provide an up-to-date review on the topic.
