Predictive Factors for a New Positive Nasopharyngeal Swab Among Patients Recovered From COVID-19.

Introduction: As an emerging infectious disease, the clinical and virologic course of COVID-19 requires better investigation. The aim of this study is to identify the potential risk factors associated with persistent positive nasopharyngeal swab real-time reverse transcription‒polymerase chain reaction tests in a large sample of patients who recovered from COVID-19.

Methods: After the acute phase of SARS-CoV-2 epidemic infection, the Fondazione Policlinico A.

β-Adrenergic Receptor Signaling and Heart Failure: From Bench to Bedside.

Despite improvements in management and therapeutic approach in the last decades, heart failure is still associated with high mortality rates. The sustained enhancement in the sympathetic nervous system tone, observed in patients with heart failure, causes alteration in β-adrenergic receptor signaling and function. This latter phenomenon is the result of several heart failure-related molecular abnormalities involving adrenergic receptors, G-protein-coupled receptor kinases, and β-arrestins.

Neurophysiological Measures and Alcohol Use Disorder (AUD): Hypothesizing Links between Clinical Severity Index and Molecular Neurobiological Patterns.

Background: In 1987, Cloninger proposed a clinical description and classification of different personality traits genetically defined and independent from each other. Moreover, he elaborated a specific test the TCI to investigate these traits/states. The study of craving in Alcohol Use Disorder (AUD) assumed a greater significance, since ever more data seems to suggest a direct correlation between high levels of craving and a higher risk of relapse in alcoholics.

A prospective study on ambulatory care provided by primary care pediatricians during influenza season.

Aim of this study was to obtain a picture of the nature of the primary care pediatricians' visits during a winter season. We investigated reasons for visits, diagnosis, and pattern of prescription in 284 children. The reason for visit was a planned visit in 54% of cases, a well-being examination in 26%, and an urgent visit for an acute problem in 20% of cases.
