Structural and Functional Pulmonary Assessment in Severe COVID-19 Survivors at 12 Months after Discharge.

Long-term pulmonary sequelae in COVID-19 patients are currently under investigation worldwide. Potential relationships between blood sampling and functional and radiological findings are crucial to guide the follow-up. In this study, we collected and evaluated clinical status, namely symptoms and patients' reported outcome, pulmonary function tests (PFT), laboratory tests, and radiological findings at 3- and 12-months post-discharge in patients admitted between 25 February and 2 May 2020, and who survived severe COVID-19 pneumonia. A history of chronic pulmonary disease or COVID-19-unrelated complications were used as exclusion criteria. Unenhanced CTs were analyzed quantitatively (compromising lung volume %) and qualitatively, with main patterns of: ground-glass opacity (GGO), consolidation, and reticular configuration. Patients were subsequently divided into groups based on their radiological trends and according to the evolution in the percentage of compromised lung volume. At 12 months post-discharge, seventy-one patients showed significantly improved laboratory tests and PFT. Among them, 63 patients also underwent CT examination: all patients with negative CT findings at three months (n = 14) had negative CT also at 12 months; among the 49/63 patients presenting CT alterations at three months, 1/49 (2%) normalized, 40/49 (82%) improved, 7/49 (14%) remained stably abnormal, and 1/49 (2%) worsened. D-dimer values were low in patients with normal CT and higher in cases with improved or stably abnormal CT (median values 213 vs. 329 vs. 1000 ng/mL, respectively). The overall compromised lung volume was reduced compared with three months post-discharge (12.3 vs. 14.4%, p < 0.001). In stably abnormal CT, the main pulmonary pattern changed, showing a reduction in GGO and an increase in reticular configuration. To summarize, PFT are normal in most COVID-19 survivors 12 months post-discharge, but CT structural abnormalities persist (although sensibly improved over time) and are associated with higher D-dimer values.

[Risk factors for falls in the pediatric setting at the Hospital Agency of United Hospitals of Bergamo: a retrospective observational study]. / Fattori di rischio cadute in ambito pediatrico nell'Azienda Ospedaliera Ospedali Riuniti di Bergamo: studio osservazionale retrospettivo.

PURPOSE: To identify the main and most significant risk factors for falls and improve the quality of care delivered to pediatric patients by providing indications for interventions for the prevention of falls. METHODS: To investigate the correlation between falls and risk factors a retrospective observational case-control study was carried out, the sample was made up by all children who fell from 2004 to 2011 between 0-18 y.o. for which there was a record of the fall. RESULTS: 108 children were included in the study (36 cases and 72 controls). The data showed that 4 drugs have a correlation with falls,on the contrary intravenous therapy seemed to be a factor that protects against the risk of falling. CONCLUSION: The study confirms the importance of the problem of falls in children. A greater sample size could help to identify additional independent variables. This study may represent a starting point for further analysis.
