Awake pronation with helmet continuous positive airway pressure for COVID-19 acute respiratory distress syndrome patients outside the ICU: A case series.

OBJECTIVE: Continuous positive airway pressure (CPAP) is an important therapeutic tool in COVID-19 acute respiratory distress syndrome (ARDS) since it improves oxygenation, reduces respiratory rate and can prevent intubation and intensive care unit (ICU) admission. CPAP during pronation has seldom been described and never during sedation. DESIGN: Case series. SETTING: High dependency unit of San Carlo University Hospital (Potenza, Italy). PATIENTS: Eleven consecutive patients with COVID-19 ARDS. INTERVENTION: Helmet CPAP in prone position after failing a CPAP trial in the supine position. MAIN VARIABLE OF INTEREST: Data collection at baseline and then after 24, 48 and 72h of pronation. We measured PaO2/FIO2, pH, lactate, PaCO2, SpO2, respiratory rate and the status of the patients at 28-day follow up. RESULTS: Patients were treated with helmet CPAP for a mean±SD of 7±2.7 days. Prone positioning was feasible in all patients, but in 7 of them dexmedetomidine improved comfort. PaO2/FIO2 improved from 107.5±20.8 before starting pronation to 244.4±106.2 after 72h (p<.001). We also observed a significantly increase in Sp02 from 90.6±2.3 to 96±3.1 (p<.001) and a decrease in respiratory rate from 27.6±4.3 to 20.1±4.7 (p=.004). No difference was observed in PaCO2 or pH. At 28 days two patients died after ICU admission, one was discharged in the main ward after ICU admission and eight were discharged home after being successfully managed outside the ICU. CONCLUSIONS: Helmet CPAP during pronation was feasible and safe in COVID-19 ARDS managed outside the ICU and sedation with dexmedetomidine safely improved comfort. We recorded an increase in PaO2/FIO2, SpO2 and a reduction in respiratory rate.

Publication trends of papers on schizophrenia. A 15-year analysis of three general psychiatric journals.

BACKGROUND: We assessed the publication trends of papers on schizophrenia through an analysis of the articles published by three general psychiatric journals (Archives of General Psychiatry (AGP), the British Journal of Psychiatry (BJP), and the Australian and New Zealand Journal of Psychiatry (ANZJP) from three continents. METHOD: For each of the journals, we covered the period between 1980 and 1994. We carried out both a quantitative analysis, assessing the trends over time in the publication of papers on schizophrenia, and a qualitative analysis, classifying the articles into eight scientific fields. RESULTS: During the study period a total of 943 articles dealing with schizophrenia were published in the three journals evaluated; the proportion of papers focusing on schizophrenia was higher in the AGP and in the BJP (18 and 15%) as compared with the ANZJP (5.6%). A substantially higher proportion of basic science articles was published in the AGP as compared with the BJP and the ANZJP, whereby a somewhat larger representation of epidemiological and psychosocial research was found in the latter journals. CONCLUSIONS: Given the importance of schizophrenia in psychiatric research and practice, it will be useful to regularly monitor the research trends in this specific field.
