Recurrent spontaneous pneumomediastinum: a rare but possible event!

A number of risk indices have been formulated in an attempt to predict risk of a major hemorrhage in an individual on warfarin therapy. No single index to date is able to reliably predict this risk in an individual patient. Although most warfarin related hemorrhages are gastrointestinal or intracranial in origin this case represents a particularly rare entity of a major hemorrhage presenting as an encysted empyema. To the best of our knowledge this has never before been described

SIRT1 Activity in Peripheral Blood Mononuclear Cells Correlates with Altered Lung Function in Patients with Chronic Obstructive Pulmonary Disease

Oxidative stress is a recognized pathogenic mechanism in chronic obstructive pulmonary disease (COPD). Expression of the NAD+-dependent deacetylase Sirtuin 1 (SIRT1), an antiaging molecule with a key role in oxidative stress response, has been described as decreased in the lung of COPD patients. No studies so far investigated whether systemic SIRT1 activity was associated to decreased lung function in this disease

Outcomes of Thoracoscopic Lobectomy after Recent COVID-19 Infection

Background: The COVID-19 outbreak had a massive impact on lung cancer patients with the rise in the incidence and mortality of lung cancer. Methods: We evaluated whether a recent COVID-19 infection affected the outcome of patients undergoing thoracoscopic lobectomy for lung cancer using a retrospective observational mono-centric study conducted between January 2020 and August 2022. Postoperative complications and 90-day mortality were reported. We compared lung cancer patients with a recent history of COVID-19 infection prior to thoracoscopic lobectomy to those without recent COVID-19 infection. Univariable and multivariable analyses were performed. Results: One hundred and fifty-three consecutive lung cancer patients were enrolled. Of these 30 (19%), had a history of recent COVID-19 infection prior to surgery. COVID-19 was not associated with a higher complication rate or 90-day mortality. Patients with recent COVID-19 infection had more frequent pleural adhesions (p = 0.006). There were no differences between groups regarding postoperative complications, conversion, drain removal time, total drainage output, and length of hospital stay. Conclusions: COVID-19 infection did not affect the outcomes of thoracoscopic lobectomy for lung cancer. The treatment of these patients should not be delayed in case of recent COVID-19 infection and should not differ from that of the general population

Audit on the appropriateness of integrated COPD management: The "aLT-BPCO" project

Background: Non communicable chronic diseases (including respiratory ones) are the leading cause of death and disability. To cope with them we need to redesign the health system, improving primary prevention, screening, and outpatient services, while fully integrating different branches of the health service. The Italian Ministry of Health published extended guidelines on integrated COPD management (COPD-GL) in 2010. In 2011 a condensed version was produced. These documents define appropriateness of management regarding both the specialist and the health service. Methods: An internal audit on how clinical practice conforms to COPD-GL standards was implemented in one Italian region involving 29 respiratory units (RU) (65.8% of the total regional RU): data were collected from the clinical database at time zero and after 6 months. In the meantime, specialists of RU underwent education on COPD-GL. Results: At time zero, significant gaps between current practice and recommendations emerged both in medical practice (mean agreement 25%) and in the health organization (48%). At month 6 the gaps were reduced more in clinical practice (60.7%) than in organization (54.7%). Conclusions: It is easier to resolve the gaps in specialist clinical practice than the organizational gaps, changing which is the politicians' task. Correcting specialists' inappropriateness may be worthless if this is not accompanied by improvement of the organizational obstacles. The search for appropriateness should not be limited only to specialists or to a strict control of drug prescription but should include all the organizational aspects. Implementation of COPD-GL calls for actions on the part of both specialists and the health system
