Frequency of face touching with and without a mask in pediatric hematology/oncology health care professionals.

The impact of wearing a mask on face-touching behavior is unknown. We conducted a survey of pediatric hematology/oncology staff to assess the perception of how masks would affect face-touching behavior and a brief observational study of providers during conferences in a children's hospital to quantify how masks affect face-touching behavior. Most felt that the mask would either increase (37.4%) or decrease (36.6%) their face-touching behavior. During a total of 330 person-minutes of observation, median face-touching rate was 5.4 face touches/hour (FT/h) while wearing a mask and 20 FT/h without a mask. Masks may reduce face-touching behavior amongst health care professionals.

Association of Cardiac Abnormalities to the Frail Phenotype in Cirrhotic Patients on the Waitlist: From the Functional Assessment in Liver Transplantation Study.

BACKGROUND: Frailty is a syndrome of decreased physiologic reserve that results from compromise of multiple physiologic systems including cardiovascular system. We aimed to determine the association between the frail phenotype and cardiac abnormalities in liver transplant (LT) candidates through evaluation of transthoracic echocardiography (TTE) indices. METHODS: Included were consecutive outpatients listed for LT who underwent a frailty assessment from January 1, 2014, to June 30, 2016 (using the Liver Frailty Index) and a 2-dimensional/Doppler TTE examination. Patients were categorized as robust, intermediate frail, or frail by the Liver Frailty Index based on scores of less than 3.2, between 3.2 and 4.5, or 4.5 or greater. Linear regression assessed associations between the Liver Frailty Index and TTE indices. RESULTS: Of 335 patients, 19% were robust, 65% intermediate frail, and 16% frail. TTE indices of left atrial (LA) dilatation differed significantly by frailty status: median LA dimension (P = 0.03), LA volume index (LAVI mL/m; P < 0.001) and %LAVI > 34 mL/m (P = 0.001). In linear regression adjusted for age, sex, hypertension, and diabetes, the Liver Frailty Index was positively associated with LA dimension (coeff, 0.20; 95% confidence interval [CI], 0.07-0.34), LAVI mL/m (coeff, 0.01; 95% CI, 0.005-0.02), ejection fraction (coeff, 1.59; 95% CI, 0.32-2.85), and pulmonary artery systolic pressure (coeff, 0.01; 95% CI, 0.003-0.02), and negatively associated with LV hypertrophy (coeff, -0.22; 95% CI, -0.37 to -0.06). CONCLUSIONS: In LT candidates, frailty is associated with cardiac structural and functional changes, independent of known risk factors. Our study provides evidence to support that measures of frailty in cirrhotic patients encompass abnormalities of the cardiovascular system and may inform assessments of cardiovascular reserve in this population.
