ABSTRACT
The role of noninvasive positive pressure ventilation (NIPPV) in COVID-19 patients with acute hypoxemic respiratory failure (AHRF) is uncertain, as no direct evidence exists to support NIPPV use in such patients. We retrospectively assessed the effectiveness and safety of NIPPV in a cohort of COVID-19 patients consecutively admitted to the COVID-19 general wards of a medium-size Italian hospital, from March 6 to May 7, 2020. Healthcare workers (HCWs) caring for COVID-19 patients were monitored, undergoing nasopharyngeal swab for SARS-CoV-2 in case of onset of COVID-19 symptoms, and periodic SARS-CoV-2 screening serology. Overall, 50 patients (mean age 74.6 years) received NIPPV, of which 22 (44%) were successfully weaned, avoiding endotracheal intubation (ETI) and AHRF-related death. Due to limited life expectancy, 25 (50%) of 50 NIPPV-treated patients received a "do not intubate" (DNI) order. Among these, only 6 (24%) were weaned from NIPPV. Of the remaining 25 NIPPV-treated patients without treatment limitations, 16 (64%) were successfully weaned, 9 (36%) underwent delayed ETI and, of these, 3 (33.3%) died. NIPPV success was predicted by the use of corticosteroids (OR 15.4, CI 1.79-132.57, p 0.013) and the increase in the PaO2/FiO2 ratio measured 24-48 h after NIPPV initiation (OR 1.02, CI 1-1.03, p 0.015), while it was inversely correlated with the presence of a DNI order (OR 0.03, CI 0.001-0.57, p 0.020). During the study period, 2 of 124 (1.6%) HCWs caring for COVID-19 patients were diagnosed with SARS-CoV-2 infection. Apart from patients with limited life expectancy, NIPPV was effective in a substantially high percentage of patients with COVID-19-associated AHRF. The risk of SARS-CoV-2 infection among HCWs was low.

The purpose of this prospective observational study was to evaluate the yield and clinical impact of blood cultures in a 78-bed Internal Medicine ward of a medium-sized Italian acute care hospital. During a two-month study period, 154 (mean age: 75.2 ++ 12.2 years; 94 males) out of 620 (24.8%) hospitalized patients underwent 174 blood cultures and were enrolled in the study. The rate of true-positive cultures was 11.5% (20/174) and the rate of false-positive (contaminants) was 5.7% (10/174). A total of 23 microorganisms (5 multidrug resistant strains), most frequently Escherichia coli (n = 10), Klebsiella pneumoniae (n = 3) and Staphylococcus aureus (n = 3), were isolated. The positivity rate was significantly higher in patients with urinary tract infection (31%) and abdomen infection (26.1%) than in patients with pneumonia (4.9%; p<0.01). Although the positivity rate in patients exposed to antibiotics was lower than in those not exposed, the difference was not statistically significant. Therapy changes due to blood culture positivity were observed in 7.1% of the patients overall. In-hospital death was observed in nine of the 136 patients with negative blood cultures (6.6%) and in none of the 18 patients with positive blood cultures. These results indicate that the yield and clinical impact of blood cultures is quite low in patients admitted to an Internal Medicine ward and suggest the need to improve the adequacy of the indications to perform the test.

It has been suggested that preexisting thyroid disease (TD) could be a risk factor for the development of eating disorders. The aim of this study was to compare eating attitudes and behavior in female obese patients with and without TD. Thyrotropin (TSH) was determined in 256 patients aged 44.9+/-14.7 years with body mass index (BMI) >30 kg/m(2); eating attitudes and behavior were assessed with the Eating Disorder Examination (EDE). EDE Shape Concern score was significantly higher in patients with previous or current hypothyroidism (N=30) than in the rest of the sample. Among patients without known TD, no difference in eating attitudes was observed between patients with elevated TSH (N=24; 11%) and those with normal thyroid function. The prevalence of binge eating disorder (BED) in the total sample was 9.7%; no difference in prevalence was observed between patients with and without a history of hypothyroidism, and between those with and without previously unknown hypothyroidism. In conclusion, known hypothyroidism is associated with increased shape concern; this does not appear to be related to differences in current levels of thyroid hormones or related hormones.
