Nowadays, the fast development of hardware for IoT-based systems creates appropriate conditions for the development of services for different application areas. As we know, the large number of multifunctional devices, which are connected to the Internet is constantly increasing. Today, most of the IoT devices just only collect and transmit data. The huge amount of data produced by these devices requires efficient and fast approaches to its analysis. This task can be solved by combining Artificial Intelligence and IoT tools. Essentially, AI accelerators can be used as a universal sensor in IoT systems, that is, we can create Artificial Intelligence of Things (AIoT). AIoT can be considered like a movement from data collection to knowledge aggregation. AIoT-based systems are being widely implemented in many high-tech industrial and infrastructure systems. Such systems are capable of providing not only the ability to collect but also analyse various aspects of data for identification, planning, diagnostics, evaluation, monitoring, optimization, etc., at the lower level in the entire system's hierarchy. That is, they are able to work more efficiently and effectively by generating the knowledge that is needed for real-time analytics and decision-making in some application areas.

Background: In accordance with the scientific literature heavy alcohol consumption (>50g per day) represents a risk factor for several diseases development, including cancer. However, the oncogenic role of light alcohol drinking ( Objective: To assess the scientific knowledge about light alcohol consumption and the risk of malignancy onset. Methods: To collect the scientific evidences regarding this topic the keywords “light alcohol drinking”, “light alcohol consumption” and “cancer”, were used. Papers published during the last 15 years were analyzed, in order to select the most recent evidence. Meta-analyses with well-defined levels of alcohol intake were included in the present review. Other studies that focused on biochemical, molecular and genetic aspects, as well as duplicate articles, were excluded. : Furthermore, a possible protective role of light alcohol consumption on the development of bladder, kidney and ovarian cancer and Non Hodgkin Lymphoma was observed. Results: Twenty-nine large, meta-analyses were included in this review. Light alcohol drinking was not associated with an increased risk of cancer occurrence, with the exception of breast and prostate cancer and melanoma. Conclusion: Light alcohol drinking was not associated with the development of several malignancies, except for a light increase of melanoma, breast cancer in women and prostate cancer in men.

Background: The international health emergency caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which, at the end of 2019, hit the world, forced the govern-ments of all countries to adopt stringent restrictive measures to contain the spread of the virus. Sever-al studies have revealed worsening levels of anxiety, depression and perceived stress related to these restrictions and the resulting lifestyle changes. Some studies have also confirmed the presence of a re-lationship between SARS-CoV-2-related emotional distress and drinking behavior. Indeed, is a well-known fact that alcohol consumption is one of the behavioral strategies used to reduce negative emo-tional states. However, it was documented that young people developed different responses to alcohol use during the pandemic than adults. Objective: The aim of this work was to investigate the consumption habits of young Italians and how the consumption and purchase of alcoholic beverages have changed following the pandemic. New ways of drinking alcohol were also interesting to observe, such as online. Methods: Young people between 18 and 35 years old were subjected to an anonymous questionnaire of 22 questions on the adoption of forms of behavior at risk through alcohol consumption, the quanti-ty and occasions of preferential consumption, and on the methods and quantities of alcoholic bever-age purchase, before and during the SARS-CoV-2 pandemic. The subjects who declared themselves "non-drinkers" were not included in the statistical survey. Results: About 33% of the enrolled "drinkers" (268/823), adopted risky forms of alcoholic behavior. Males reported a higher average habit of drinking wine or alcohol (M = 1.9953 ± 1.39743, F = 1.7373 ± 1.36688, p Conclusion: A change in alcohol consumed and alcohol purchased before and during the SARS-CoV-2 pandemic was revealed.

The activity of the SARS-CoV-2 virus has not yet been studied in a post-mortem setting. The absence of these data has led to the prohibition of exposure of infected corpses during burial procedures. Our aim was to assess the virus’s persistence and the possibility of transmission in the post-mortem phase including autopsy staff. The sample group included 29 patients who were admitted to our Covid-19 Centre who died during hospitalisation and the autopsy staff. All the swabs were subjected to a one-step real-time reverse transcription polymerase chain reaction with cycle threshold (Ct) values. Swab collection was performed at 2 h, 4 h, 6 h, 12 h, over 24 since death. The following were the analysis of patients’ swabs: 10 cases were positive 2 h after death; 10 cases positive 4 h after death; 9 cases were found positive 6 h after death; 7 cases positive 12 h after death; 9 cases remained positive 24 h after death. The swabs performed on all the forensic pathologist staff on duty who performed the autopsies were negative. The choice to avoid rituals and the display of corpses before and at the burial procedures given appears cautiously valid due to the persistence of the SARS-CoV-2 virus in the post-mortem period. Although the caution in choosing whether or not to perform an autopsy on infected corpses is acceptable, not to perform autopsies is not biologically supported.

BACKGROUND Urotensin II (U-II) is a vasoactive peptide that interacts with a specific receptor named UTR. Recently, our group has demonstrated increased UTR expression in both human colon adenocarcinoma cell lines and adenomatous polyps, as well as in colon carcinoma samples if compared to healthy colon samples of the same patients. We also showed that an UTR agonist induced an increase in colon adenocarcinoma cell growth in vitro, whereas the UTR block with a specific antagonist caused an inhibition of their growth and an inhibition of about 50% of both motility and cell invasion. Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) associated with an increased baseline risk for colon cancer compared with the general population, and this risk is mostly attributed to chronic inflammation and immune dysregulation. This risk increases along with the duration of the disease, as demonstrated by many studies. There are no UTR expression data related to UC, and we therefore evaluated UTR expression in ill colon biopsies and in healthy colon ones of patients with UC and colon biopsies of healthy patients. METHODS We enrolled, prior to informed consent, 11 patients (5 males and 6 females, age range 29-75 years, median age 52 years) with first UC diagnosis compared to 11 healthy controls (6 males and 5 females, age range 30-78 years, median age 55 years). We have therefore sampled inflammatory and healthy tissue in UC patients. We have also taken colic tissue samples in healthy subjects. Evaluation of receptor expression was performed by reverse transcription-polymerase chain reaction (RT-PCR), Western Blot analysis. The ANOVA Test (P

Alcohol represents the oldest substance of abuse known and Alcoholic Liver Disease (ALD) is the most common cause of chronic liver disease worldwide. The ALD includes a wide spectrum of injury and may lead progressively from simple steatosis to frank cirrhosis. The ALD diagnosis may be hard and it is mainly defined by the history of chronic alcohol intake, physical and laboratory abnormalities suggestive of liver disease. Abstinence is the cornerstone of ALD therapy. Although the burden on health of ALD is not negligible, in the last decades few therapeutic advances have been made. Because of the complex pathogenetic mechanisms, the therapy of ALD and especially of severe Alcoholic Hepatitis (AH), represents a thorny problem in the clinical practice. In severe forms of acute AH, some specific drug treatments, including glucorticoids or pentoxifylline, have been defined and are, at the moment, recommended by international guidelines. On the contrary, specific long-term treatments of ALD, aimed at stopping the progression of fibrosis, are not yet approved.

Background Endoscopic ultrasound (EUS) has been used in the clinical arena for almost 35 years and it is now well-integrated in everyday hospital practice. Method We conducted a systematic review of the available English-language articles. Objective The purpose of this review is to summarize the relevant applications of operative EUS. Results More than 5000 scientific papers published in the literature have demonstrated its high accuracy for the diagnosis and staging of a variety of benign and malignant conditions. The main indications of operative EUS, both diagnostic and therapeutic, are related to its ability to combine ultrasound imaging and safe and effective needle insertion into lesions originating from the gut wall and from organs nearby. In addition, technologic advancements of echoendoscopes with a therapeutic working-channel have allowed to perform several EUS-guided interventions, i.e. celiac plexus neurolysis, drainage of fluid collections, drainage of dilated biliary and pancreatic ducts, and vascular interventions.

Background Endoscopic Ultrasound has been used in the clinical arena for almost 35 years and it is now well-integrated in everyday hospital practice. Method We conducted a systematic review of the available English-language articles. Objective The purpose of this review is to summarize all the relevant indications to endoscopic ultrasound and analyze its relevant data in terms of accuracy and clinical outcomes. Results More than 5000 scientific papers published in the literature have demonstrated its high accuracy for the diagnosis and staging of a variety of benign and malignant conditions. Staging indications include gastroesophageal and rectal cancers. Diagnostic, staging and therapeutic indications include diseases of the pancreaticobiliary area. Finally, differential diagnosis of submucosal tumors represents another important indication to this technique.

Alcohol represents the oldest substance of abuse known, existed at least as early as the Neolithic period. In the present era, almost half of the world’s population consumes alcohol and it represents the third largest risk factor for disease and disability and the most prevalent cause of advanced liver disease worldwide. In fact, when alcohol consumption reaches "unsafe quantities" an Alcoholic Liver Disease (ALD) is very likely. ALD comprises a large spectrum of diseases, ranging from simple steatosis to steatohepatitis with fibrosis and cirrhosis. Alcohol related cirrhosis is responsible of almost 50% of all cirrhosis-related and 1% of all-cause deaths worldwide. Even if ALD and alcoholic cirrhosis represent a large part of liver diseases, to know exactly the global burden of these phenomena is very difficult. This is mostly due to diagnostic and nosological issues, being ALD represented by several types of diseases and the diagnosis very often based on voluntary questionnaires. Also the natural history of ALD is somewhat difficult to predict, since there is not a definite evolution between the various stages of the disease and, indeed, they may coexist in a single subject. In this brief review we will report on the global burden of ALD, the principal factors influencing its prevalence among populations and the different presentations of its natural history.

Alcoholic and virus C hepatitis currently represent the main causes of chronic liver disease worldwide. Every year many people die and are subjected to complex hospitalization and medical assistance due to these pathologies. Alcoholic liver disease and hepatitis C virus chronic infection are often present in the same patient. These two pathologies sinergically act in determining the onset and progression of liver damage that, from the chronic hepatitis staging, may rapidly progress to fibrosis, cirrhosis and hepatocellular carcinoma. In this review we analysed physiopathological aspects and biomolecular interactions that relate ethanol and hepatitis C virus in determining liver damage; moreover we took into account the effect on the natural history of liver disease deriving from the co-presence of these pathologies. Therefore we paid particular attention to the ability of ethanol and hepatitis C virus to in inducing oxidative stress or lipid accumulation, and analyzed the basic mechanisms of fibrogenesis that both diseases have got, amplified by their co-presence in the same patient. Finally we paid attention to the oncogenetic mechanisms inducing hepatocellular carcinoma and variability of response to antiviral therapy that derives from alcohol abuse in a subject affected by C hepatitis.

Several skin manifestations were described in patients affected by intestinal disorders. The development of skin diseases in these patients could be related to the impairment of intestinal absorption and motility, other than to immunological and hormonal changes. The growing evidence of the association between skin disorders and intestinal diseases suggests that the skin could be considered the ‘mirror of the gut’.
