Background and Objectives. A relatively small number of studies have investigated the characteristics, comorbidities and laboratory measures associated with prognosis in patients with COVID-19, admitted to Internal Medicine Units (IMU) in Italy. Therefore, we performed a retrospective multicentre study to identify baseline features, predisposing to severe disease and poor outcomes, in adult individuals with SARS-CoV2 infection, hospitalized in 5 IMUs in the Emilia-Romagna region (Italy). Materials and Methods. We included 129 consecutive patients (male 75, median age 68 years) from 1st March 2020 to 31st October 2021. Patients’ baseline characteristics, comorbidities, laboratory measures, and outcomes were collected. Results. At admission, the factors significantly associated with a higher risk of in-hospital mortality included: age (median 68 vs. 83 years in survived vs. dead patients, P=0.000), diabetes [Odds Ratio (OR) 4.00, P=0.016], chronic obstructive pulmonary disease (OR 4.60, P=0.022), cancer (OR 5.81, P=0.021), acute- (OR 9.88, P=0.000) and chronicrenal failure (OR 6.76, P=0.004). During the study period, 16 individuals died (12.4%), all over 70 years old. In deceased vs. non-deceased patients were detected: i) more elevated white blood cells and neutrophils-counts and lower lymphocytes count; ii) higher levels of total/direct bilirubin, creatinine, C-reactive-protein, lactate-dehydrogenase, ferritin, but only a slight Interleukin-6 increase; iii) a trend of lower vitamin D values. Conclusions. We proposed a new I index, a modified form of the Age-Adjusted Charlson Comorbidity Index, by considering pO2/FiO2 ratio, to better characterize the severity of COVID-19. Furthermore, we critically discuss our results with the current assumption which considers COVID-19 as a pathological condition associated with cytokine storm. [ABSTRACT FROM AUTHOR]

Non-invasive ventilation (NIV) is a rapidly spreading method in the last years even outside of intensive care units for the treatment of patients with acute respiratory failure. Its use in general medical wards in Italy and Europe is still largely incomplete and there are clear gaps in terms of organization, training, selection, and patient monitoring. If these gaps are filled, NIV has also proven to be effective in general medical wards, especially if they have a critical care area. This publication reports the data collected by an Italian regional survey on the use of NIV in internal medicine, highlighting positive and negative aspects. [ABSTRACT FROM AUTHOR]

Oxygen (O2) therapy consists in the administration of a gas mixture with a percentage of O2 increased and it is one of the most common aids used in hypoxia. In this paper we presented the data analyzed by Huang, as a pretext to try to provide an explanation of the physiopathological effects of oxygen administration on tissue oxygenation. The rationale of O2 therapy is to increase the inspired partial pressure of O2, increasing the fraction of inspiratory O2. Oxygen induces a vasoconstriction on sistemic circulation and this effect reduces the cardiac output, increasing the afterload. The mechanisms by which hyperoxia induces vasoconstriction are different. Oxygen also has effects on lung function, redox balance, and it is involved in the production of reactive O2 species (ROS) and other systemic effects, which in turn are involved in the changes of reduced oxygen delivery (DO2). This last would possibly help to consider carefully the risk of DO2 in each patient. [ABSTRACT FROM AUTHOR]

High-flow nasal cannula (HFNC) are an oxygen therapy device developed in the last years for the treatment of patients with acute or acute on chronic hypoxemic respiratory failure with different etiology and severity (including covid-19 pneumonia). HFNC combine the possibility of delivering high flows of gases, actively humidified and heated, with the use of a comfortable nasal interface, resulting generally well tolerated by most patients. In light of these characteristics, together with the simplicity of use and versatility, they have spread not only in intensive and semi-intensive care units but also in general medical ward in which they can play an important role in the treatment of elderly, frail patients with comorbidity where other more aggressive and invasive methods of ventilations are not indicated or not practicable.

The hyperglycemic reaction to stress is part of adaptive metabolic response to critical illness, especially hypoxia, hemorrhage and sepsis. It involves neuro-endocrine and immune pathways leading to the development of insulin resistance and hepatic glucose production by gluconeogenesis and glycogenolysis. Over the last years the concept of stress related hyperglycemia has been replaced by the concept of dysglycemia and its three domains: hyperglycemia, hypoglycemia and glycemic variability. Each of the three domains is independently associated with increased risk of mortality in patients admitted in intensive care unit and non critically ill patients, both medical and surgical. The strongest association with mortality is demonstrated for hypoglycemia, with additive negative effects for hyperglycemia and glycemic variability. The influence of pre-existing diabetes mellitus on the relation of the three domains of dysglycemia with mortality is not clear, suggesting that patients affected by diabetes mellitus may tolerate a larger glucose variability. Advances in continuous glucose monitoring systems and insulin therapy algorithms may reduce the development of glycemic variability and hypoglycemia, but the benefits in clinical practice have not yet been established in clinical trials.

In order to improve the organization of a General Medical ward without a real critical care area and to optimize treatment of patients with acute respiratory failure, we developed a cart for non-invasive ventilation to be used at the patient bedside. In the rear panel, we set two i.v. drip poles used for i.v. therapy and to hold two Venturi-like flow generators for continuous positive airway pressure. On the top, two ventilators are present, a smaller one (domiciliary) and a bigger one (intensive care unit ventilator). In the front panel, there are 4 drawers called "blood - drugs", "oxygenation", "CPAP", "ventilation", in which all the devices for ventilation, oxygenation, aerosol and medical therapy are easily and quickly available. The management of acute respiratory failure is simpler, easier and safer with this cart: each necessary device is immediately available, and this avoids wasting time. This bedside non-invasive ventilation cart, as far as the cardiac emergency cart, can be useful in general medical wards lacking a critical care area in order to improve interventions in patients with acute respiratory failure.

Benign multicystic peritoneal mesothelioma is a rare malignancy with unknown etiology, first described in 1980, which have been reported to date about 150 cases in the literature. Although the term "benign", used mainly to distinguish it from the classic malignant mesothelioma, a more aggressive cancer, is considered "borderline" in terms of aggression: it tends to local recurrence but cases of lymph node metastases or in other locations at a distance are not described. The symptoms are often vague and nonspecific (abdominal pain, enlarged abdomen and ascites). The common diagnostic imaging techniques (CT, MRI) may appear similar to ovarian or peritoneal cancer by more aggressive mesenchymal neoplasms. Histological examination, accurately with the aid of immunohistochemical techniques, is therefore essential for diagnosis. Treatment is surgical and consists of peritonectomy. After surgery, the prognosis is generally good. In 50% of cases may have local recurrences; so rigorous follow-up is indicated.

Background: The application of a Continuous Positive pressure to Patient's airway (CPAP) represents one of the most important respiratory treatments during Acute Respiratory Failure (ARF) due to Acute Cardiogenic Pulmonary Edema (ACPE). Thanks to its hemodynamic and ventilatory effects, CPAP improves clinical and gasanalytic parameters and lead to a decrease of mortality and need of intubation in these patients. CPAP can be applied with different devices: ventilators, Venturi-like flow generators and Boussignac's device., Aim: To verify and to compare effectiveness and tolerability of two different CPAP's devices (Venturi-like flow generator and Buossignac's device) in ARF due to ACPE. The study was performed in a General Medical Ward., Materials and Methods: 20 patients with ARF due to ACPE were randomized in two group: the first group (10 patients) received CPAP with a Venturi-like flow generator, the second group (10 patients) with Boussignac's device. At the end of CPAP treatment each patient gave a score to tolerability., Results: In each group we noted a significant (p<0.05) improvement in clinical and gasanalytic parameters since the first hour of treatment; these improvements were confirmed in following determinations and were not significantly different in the two group of patients. The Boussignac group showed a better tolerability., Conclusions: The two CPAP's devices resulted similar in term of effectiveness. Boussignac's device has shown a better tolerability: this characteristic, together with the simple use, should stimulate the diffusion of this device where a flow generator or a ventilator are not present (outside Intensive Care Units, for example in General Medical Wards).

Prevalence and influence on liver disease of HCV and HGV infections, and HCV genotypes were studied in 28 HCV-Ab positive multitransfused thalassaemia patients with persistently normal ALT levels (group A) matched by sex and age with 28 patients with increased ALT levels (group B). Laboratory and virologic tests (all patients), liver biopsy (28 patients) and LIC by SQUID (30 patients) were performed. In group A, HCV-RNA was positive in 39%, genotype 2a was detected in 91%. In Group B, HCV-RNA was positive in 89%, prevalence of genotype 1b and 2a was 52% and 48% respectively; compared with group A, they had significantly increased values of gammaGT, AF, BA, TP, IgG, IgA, LIC (group B: 2,142 -/+ 1,524 microg/g liver; group A: 1,084 -/+ 610 microg/g liver). Overall prevalence of HGV-RNA was low (12.5%) and not significantly different between groups. Liver biopsies revealed no cirrhosis and severe fibrosis was found in 3 HCV viremic patients in group B. In 14 viremic patients examined both for LIC and liver histology, mild fibrosis was observed in 71%, in which iron overload was below 5 times the normal value. In conclusion, in patients with normal ALT levels, active HCV infection must be excluded by evaluation of HCV-RNA. Liver biopsy is indicated in HCV viremic patients, independent of ALT levels; in non-viremic patients, increased ALT levels may be due to iron overload and LIC measurement is indicated. Our data emphasise the crucial role of chelation therapy to maintain low LIC levels in order to prevent progression of fibrosis to cirrhosis in patients with HCV chronic hepatitis.
