A credere nell'Astrologia la pandemia da COVID-19 poteva essere agevolmente prevista in quanto era già scritta nelle stelle (per la congiunzione di Saturno e Plutone in Capricorno!!!)1. Ma de-sideri e con-siderazioni riprendono etimologicamente il termine latino sidus, sideris (plurale sidera). "De-siderare", composto dalla particella privativa "de-" significherebbe, letteralmente, condizione in cui sono assenti le stelle e quindi le loro influenze e i loro presagi. "Con-siderare" è il suo naturale opposto al positivo, ovvero parafrasando "stare con le stelle", in condizioni cioè di prevedere e giudicare...

Objective: We report a case series of 4 patients with type 1 diabetes who used hybrid closed-loop insulin pumps (Medtronic MiniMed 670 G) during hospitalization. Methods: Clinical data and point-of-care glucose values are presented for each patient. Glucose values are shown graphically while in manual mode as well as in auto mode. Results: The first case was a 30-year-old man admitted for pancreatitis. Mean point-of-care blood glucose was 165...

The 'flu, caused mostly by influenza A and B viruses, represents a major public health issue. Despite vaccines and antiviral drugs, the therapeutic arsenal is still suboptimal. Recently, several studies have reported the antiviral and anti-inflammatory properties of several host metabolites. Now, we show that a metabolite (called here "C2") has a potent anti-influenza activity by blocking the viral replication and by limiting the downstream pro-inflammatory signalling. These results pave the way for the development of innovative metabolic therapy against influenzal pneumonia...

BACKGROUND: Influenza virus is one of the most important human pathogens, causing substantial seasonal and pandemic morbidity and mortality. Houttuynia cordata is a traditionally used medicinal plant for the treatment of pneumonia. Flavonoids are one of the major bioactive constituents of Houttuynia cordata. PURPOSE: This study was designed to investigate the therapeutic effect and mechanism of flavonoid glycosides from H. cordata on influenza A virus (IAV)-induced acute lung injury (ALI) in mice...

Influenza rates for the US Army and West Point cadets showed that seasonal influenza was not necessarily an annual event, and there was little influenzal illness in the decade before 1918 except for 1911 and 1916. Annual records from 1862-1918 also indicated a similar paucity of influenzal illness before 1890.

Influenza virus infection is now recognised as a risk factor for invasive pulmonary aspergillosis (IPA). Delays in diagnosis contribute to delayed commencement of antifungal therapy. In addition, the emergence of resistance to first-line triazole antifungal agents puts emphasis on early detection to prevent adverse outcomes. We present 2 allogeneic stem cell transplant patients who developed IPA due to triazole-resistant Aspergillus fumigatus following influenza infection. We underline the challenges faced in the management of these cases, the importance of early diagnosis and need for surveillance given the emergence of triazole resistance...

Defensins are a family of host defense peptides present in vertebrates, invertebrates and plants. They display broad antimicrobial activity and immunomodulatory functions. Herein, the natural anti-influenzal role of β-defensins, as well as their potential usage as anti-influenza vaccine adjuvants and therapeutic agents, is reviewed. This article summarizes previously published information on β-defensin modes of action, expression changes after influenza infection and vaccination, biotechnological usage and possible boosting of their production by dietary supplementation...

Oxidative stress, Nrf2-HO-1 and TLR-MAPK/NF-κB signaling pathways have been proved to be involved in influenza A virus (IAV) replication and influenzal pneumonia. In the previous studies, we have performed several high-throughput drug screenings based on the TLR pathways. In the present study, through plaque inhibition test, luciferase reporter assay, TCID50 , qRT-PCR, western blotting, ELISA and siRNA assays, we investigated the effect and mechanism of action of curcumin against IAV infection in vitro and in vivo...

Background : Acute influenza-associated encephalopathy/encephalitis (IAE) in adults is a rare but well-known complication of influenza virus infection. The diagnosis is difficult to make due to the absence of distinctive clinical symptoms and validated diagnostic criteria. We present an illustrative case and a case review on acute IAE in adults. Methods : We performed a Medline search of the English literature using the terms influenz*, encephal* and adult, and constructed a database of detailed descriptions of patients with influenza virus infection with influenza-like symptoms at the onset of neurological symptoms...

BACKGROUND: Influenza virus infection is very common and a significant cause of morbidity and mortality in specific populations like pregnant women. Following the 2009 pandemic, several reports on the effects of influenza virus infection on maternal health and pregnancy outcome have been published. Also the safety and efficacy of antiviral treatment and vaccination of pregnant women have been studied. In this review, we have analyzed and summarized these data. OBJECTIVE: To provide information on the influence of influenza virus infection during pregnancy on maternal health and pregnancy outcome and on the effect of treatment and vaccination...

Personal experiences with past infection events, or perceived vaccine failures and complications, are known to drive vaccine uptake. We coupled a model of individual vaccinating decisions, influenced by these drivers, with a contact network model of influenza transmission dynamics. The impact of non-influenzal influenza-like illness (niILI) on decision-making was also incorporated: it was possible for individuals to mistake niILI for true influenza. Our objectives were to (1) evaluate the impact of personal experiences on vaccine coverage; (2) understand the impact of niILI on behaviour-incidence dynamics; (3) determine which factors influence vaccine coverage stability; and (4) determine whether vaccination strategies can become correlated on the network in the absence of social influence...

Using the method of self fluorescence quenching influence of phospholipids on conformational state of HA has been studied. Interactions of HA with model phospholipids membranes are accompanied by changes of structure-dynamic protein organization. This method could be used for controlling the structure organization of proteins after receiving by virus the influenzal virusomal vaccine.

INTRODUCTION: We previously reported that in HIV-1 infected patients circulating Vdelta1 T lymphocytes (Vdelta1) increase and proliferate in vitro in response to Candida albicans (Ca). Herein, we analysed the effects of MF59 adjuvant on the Vdelta1 T cell responses to hemagglutinin (HA) and Ca in HIV-1 seropositive and seronegative adults after influenzal vaccine, to clarify th molecular mechanisms triggered in vivo by an adjuvanted vaccine against influenza virus. MATERIALS AND METHODS: 58 seropositive (HIV-1+) and 48 seronegative (HIV-1-) subjects received influenzal vaccines containing or not the MF59 adjuvant...
