The underestimated burden of aspiration event and pneumonia within hospitals: what happens after dysphagia.

Study design: Prospective observational study. Background: Despite dysphagia large prevalence and the growing ageing phenomenon occurring in European countries, aspiration events among inpatients are often underestimated, given their frequent spontaneous resolution or silent contribution to aspiration syndromes. Our main objective was to evaluate the incidence of aspiration events among medical inpatients and to identify risk factors influencing the outcome of the event. Methods: Data about aspiration events - day, hour, type and outcome of the event occurred - along with underlying patient clinical conditions at the admission were collected. Between May 2015 and September 2016, data about aspiration event occurred among medical inpatients were collected in three large Italian hospitals. Results: Patients affected by aspiration events were 135 on 102,619 cumulative days of hospitalization; they were mostly females (53%) with an average age of 82. The total incidence of aspiration events was of 1.4 every 1,000 days of hospitalization (C.I. 95%: 1.2-1.7) and the most frequent manifestation was cough (61.6%). The addition of drugs or an infection diagnosis during the 24 hours preceding the event acted as risk factors for those events that needed additional interventions during the hospitalization (OR 3.1 e OR 1.9 respectively), while the elimination of one or more prescribed drugs seemed to lead to aspiration events without impact on the hospitalization. Conclusions: Results showed a large incidence of aspiration events within medical wards, many of them influencing patient outcomes. Healthcare professionals' attention concerning aspiration events should be fostered during the first hours and days of hospitalization.

Correlation between serum 25-hydroxyvitamin D levels and severity of atopic dermatitis in children.

BACKGROUND: Vitamin D deficiency could be associated with the prevalence of atopic dermatitis (AD). OBJECTIVES: We carried out a study to see whether deficient/insufficient levels of vitamin D correlate with the severity of atopic skin disease. METHODS: Using the SCORAD index, we evaluated the severity of disease in 37 children (17 girls and 20 boys) aged between 8 months and 12 years with AD, consecutively enrolled in the study. Serum levels of 25-hydroxyvitamin D [25(OH)D] were determined by a chemiluminescent method. Specific IgE (sIgE) to Staphylococcus aureus enterotoxins and sIgE to Malassezia furfur were assayed by the ImmunoCAP system. anova and the Pearson correlation test were used for statistical evaluation. RESULTS: We found severe, moderate and mild AD in nine (24%), 13 (35%) and 15 (41%) children, respectively. Mean ± SD serum levels of 25(OH)D were significantly higher (P < 0·05) in patients with mild disease (36·9 ± 15·7 ng mL(-1)) compared with those with moderate (27·5 ± 8·3 ng mL(-1)) or severe AD (20·5 ± 5·9 ng mL(-1)). The prevalence of patients with sIgE to microbial antigens increased in relation to vitamin D deficiency and AD severity. CONCLUSIONS: These data suggest that vitamin D deficiency may be related to the severity of AD and advocate the need for studies evaluating the use of vitamin D as a potential treatment in patients with this disease.
