Lung ultrasound (LU) is a useful tool for monitoring lung involvement in novel coronavirus (COVID) disease, while information on echocardiographic findings in COVID disease is to date scarce and heterogeneous. We hypothesized that lung and cardiac ultrasound examinations, serially and simultaneously performed, could monitor disease severity in COVID-related ARDS. ⋯ In COVID-related ARDS, the combined lung and cardiac ultrasound proved to be an useful clinical tool in monitoring disease progression and in identifying parameters (LU score and RV/LV ratio) able to risk stratifying these patients.

Mazzini at 150: the Italian death of a London exile.
The year 2022 will mark the 150th anniversary of the death of Giuseppe Mazzini, the spiritual father of the Italian Republic and one of the best political minds of the nineteenth century. In this review, we revisit the events surrounding Mazzini's death, based on a report published in 1872 by Dr. ⋯ Rossini suggests quite strongly that Mazzini's most likely cause of death was gastroesophageal cancer complicated by aspiration pneumonia. Surprisingly, there are no published medline entries concerning the cause of death of this Italian patriot and revolutionary, who spent 41 years of his life in exile, was admired by Dickens, Meredith and Carlyle, and is considered not only one of the founding fathers of Italy but also one of the visionaries behind the idea of a United Europe.

The innate immunity works as a defence bullwark that safeguards healthy tissues with the power of detecting infectious agents in the human body: errors in the context of innate immunity identify autoinflammatory disorders (AIDs), which arise as bouts of aberrant inflammation with little or no involvement of T and B cells and neither recognized infections, nor associated autoimmune phenomena. Hereditary AIDs tend to have a pediatric-onset heralded by stereotyped inflammatory symptoms and fever, while AIDs without an ascertained cause, such as systemic juvenile idiopathic arthritis, derive from the interaction of genetic factors with environmental noxae and are unevenly defined. ⋯ The description focuses inflammasomopathies as paradigms of interleukinopathies, nuclear factor-κB -related disorders and interferonopathies. The challenges in the management of AIDs during childhood have been recently boosted by numerous therapeutic options derived from genomically-based approaches, which have led to identify targeted biologic agents as rationalized treatments and achieve more tangible perspectives of disease control.

Hyperkalemia is a potential life-threatening condition among chronic kidney disease (CKD) patients. Available estimates of the burden of this alteration in CKD are mainly derived from large administrative databases. Since K measurements in patients in these databases are often dictated by clinical reasons, longitudinal studies including pre-planned measurements of potassium independently of clinical complication/symptoms may produce more reliable estimates of the frequency and the risk factors underlying hyperkalemia in CKD patients. ⋯ Of note, venous bicarbonate levels emerged as an independent risk factor of hyperkalemia over time also in a separate analysis of patients with and without hyperkalemia at baseline. In a cohort of CKD patients including pre-planned measurements of K, 27% of patients had hyperkalemia. Metabolic acidosis and the use of drugs interfering with renin-angiotensin system were the strongest modifiable risk factors for this potentially life-threatening alteration in CKD in longitudinal analyses in the whole study cohort and in patients developing de novo hyperkalemia over time.

Emergency department (ED) patients with cellulitis requiring intravenous antibiotics may be eligible for outpatient parenteral antibiotic therapy (OPAT). The primary objective was to determine whether implementation of an OPAT clinic results in decreased hospitalizations and return ED visits for patients receiving OPAT. We conducted an interrupted time series study involving adults with cellulitis presenting to two EDs and treated with intravenous antibiotics. ⋯ Treatment failure rates were < 2% and adverse events were < 6% in both groups. Implementation of an OPAT clinic significantly reduced return ED visits for cellulitis, but did not reduce hospital admission rates. An ED-to-OPAT clinic model is safe, and has a low rate of treatment failures.
