Description, Organization, and Individual Postgraduate Perspectives of One Italian School of Anesthesia and Intensive Care.

INTRODUCTION: The study aims to describe the organization of one accredited school of Anesthesia and Intensive Care of University of Modena and Reggio Emilia, Italy. The analysis of the post-graduation period aims to measure the time-to-first job, the perceived challenges, what postgraduate residents choose as first employ, and the overall satisfaction rating of a cohort of residents completing their training until 2017 with the usual and standard training program. METHODS: We collected organization and administrative records of the five-year program of the A-IC School of 4 cohorts of residents who joined from 2009 to 2012 and we performed a survey. We also analyzed the differences among school cohorts during the medical training. In the end, it was investigated as a reason to choose hub hospitals or not. RESULTS: The focus of the training activities revolved around the operating room with a mean of 30.41 ± 6.6 (sd), months followed by Intensive care with 17.29 ± 4.49 (sd) months. Although 7.5% of the respondents were not fully satisfied of the school's program, 89.7% of residents rated their training as adequate. In fact, 97.2% respondents reported they could overcome the professional challenges they faced after graduation. The multiple variables logistic regression showed a correlation among working in hub hospitals and training performed in university hospitals with a p value of 0.015. CONCLUSION: This paper describes the postgraduation period. This point should be examined as an integral part of the accreditation procedure. Knowing the satisfaction rate, perception autonomy, and which type of hospitals are preferred can measure the education training capacity of a postgraduation school.

Malignant Gastric Outlet Obstruction Caused by Duodenal Cervix Metastasis in a Young Woman: Rendezvous Technique.

Background: Malignant gastric outlet obstruction (MGOD) is an extremely rare expression of advanced extra-gastrointestinal cancer, such as squamous cell carcinoma (SCC) of the cervix, and only sixcases are described in the literature.Because of the short life expectancyand the high surgical risk involving these patients, less invasive approaches have been developed over time, such asthe use of an enteral stent or less invasive surgical techniques (i.e., laparoscopic gastrojejunostomy). However, MGOD could make it difficult to perform an endoscopic retrograde cholangio-pancreatography (ERCP) for standard endoscopic drainage, so in this case a combined endoscopic-percutaneous technique may be performed. This article, therefore, aims to highlight the presence in the doctor's armamentarium of the "rendezvous technique", few case reports of whichare described in the literature, and, moreover, this article aims to underline the technique'sfeasibility. Case Presentation: The case is that of a 38-year-old woman who presented with MGOD three years after the diagnosis of SCC of the cervix, who successfully underwent the rendezvous technique with the resolution of duodenal obstruction. Endoscopic enteral stenting treatment with the placement of a metal stent (SEMSs) represents the mainstay of MGOD treatment compared withsurgery due to its lower morbidity, mortality, shorter hospitalization and earlier symptom relief. However, in patients with both duodenal and biliary obstruction, a combined endoscopic-percutaneous approach may be necessary because of the difficulty in passing the duodenal stricture or in accessing the papilla through the mesh of the duodenal SEMS. Conclusion: The rendezvous procedure is a technicallyfeasible and minimally invasive approach to the double stenting of biliary and duodenal strictures. It achieves the desired therapeutic result while avoiding the need to perform more invasive procedures that could have a negative impact on the patient'sprognosis.

How Artificial Intelligence and New Technologies Can Help the Management of the COVID-19 Pandemic.

The COVID-19 pandemic has worked as a catalyst, pushing governments, private companies, and healthcare facilities to design, develop, and adopt innovative solutions to control it, as is often the case when people are driven by necessity. After 18 months since the first case, it is time to think about the pros and cons of such technologies, including artificial intelligence-which is probably the most complex and misunderstood by non-specialists-in order to get the most out of them, and to suggest future improvements and proper adoption. The aim of this narrative review was to select the relevant papers that directly address the adoption of artificial intelligence and new technologies in the management of pandemics and communicable diseases such as SARS-CoV-2: environmental measures; acquisition and sharing of knowledge in the general population and among clinicians; development and management of drugs and vaccines; remote psychological support of patients; remote monitoring, diagnosis, and follow-up; and maximization and rationalization of human and material resources in the hospital environment.

The societal burden of chronic liver diseases: results from the COME study.

OBJECTIVE: Chronic liver diseases (CLDs) impose a significant socioeconomic burden on patients and the healthcare system, but to what extent remains underexplored. We estimated costs and health-related-quality-of-life (HRQoL) among patients with CLDs at different stages and with different aetiologies. DESIGN: A cost-of-illness study was conducted. Direct costs, productivity loss and HRQoL were estimated in patients with chronic hepatitis, cirrhosis hepatocellular carcinoma (HCC) or where orthotopic liver transplantation (OLT) had been performed, for hepatitis C virus (HCV) infection, hepatitis B virus (HBV) infection, or in those with liver disease from other causes. Patients were retrospectively observed for 6 months. The societal perspective was adopted to calculate costs. RESULTS: In total, 1088 valid patients (median age=59.5 years, 60% men) were enrolled. 61% had chronic hepatitis, 20% cirrhosis, 8% HCC and 12% underwent OLT. HCV infection was identified in 52% and HBV infection in 29% of the patients. Adjusted mean direct costs increased from <€200/patient-month in HCV-infected patients with hepatitis to >€3000/patient-month in HBV infected patients with OLT. Antiviral treatment was the cost driver in patients with hepatitis, while hospital costs were the driver in the other subgroups. Absenteeism increased from HBV-infected patients with hepatitis (0.7 day/patient-month) to patients with OLT with other aetiologies (3.7 days/patient-month). HRQoL was on average more compromised in cirrhosis and patients with HCC, than in hepatitis and patients with OLT. HBV-infected patients generated higher direct costs, patients with other aetiologies generated the highest productivity loss and HCV-infected patients reported the worst HRQoL levels. CONCLUSIONS: The present study can be considered a benchmark for future research and to guide policies aimed at maximising the cost-effective of the interventions.

Focus on emerging drugs for the treatment of patients with non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) has become the most common liver disorder in Western countries and is increasingly being recognized in developing nations. Fatty liver disease encompasses a spectrum of hepatic pathology, ranging from simple steatosis to non-alcoholic steatohepatitis, cirrhosis, hepatocellular carcinoma and end-stage liver disease. Moreover, NAFLD is often associated with other metabolic conditions, such as diabetes mellitus type 2, dyslipidemia and visceral obesity. The most recent guidelines suggest the management and treatment of patients with NAFLD considering both the liver disease and the associated metabolic co-morbidities. Diet and physical exercise are considered the first line of treatment for patients with NAFLD, but their results on therapeutic efficacy are often contrasting. Behavior therapy is necessary most of the time to achieve a sufficient result. Pharmacological therapy includes a wide variety of classes of molecules with different therapeutic targets and, often, little evidence supporting the real efficacy. Despite the abundance of clinical trials, NAFLD therapy remains a challenge for the scientific community, and there are no licensed therapies for NAFLD. Urgently, new pharmacological approaches are needed. Here, we will focus on the challenges facing actual therapeutic strategies and the most recent investigated molecules.

Optimized contrast-enhanced ultrasonography for characterization of focal liver lesions in cirrhosis: A single-center retrospective study.

BACKGROUND: Hepatocellular carcinoma (HCC) is the leading cause of death amongst cirrhotic patients. Its diagnosis and discrimination from non-HCC malignant lesions in cirrhosis includes contrast enhanced computed tomography (CECT), contrast enhanced magnetic resonance imaging (CEMRI), or, in selected cases, liver biopsy. The role of contrast-enhanced ultrasonography (CEUS) is still controversial. AIMS: To evaluate whether, by selecting an appropriate 'time to wash-out' cut-off value, CEUS capability of discriminating between HCC and non-HCC malignancies in cirrhotic patients may be enhanced. METHODS: We enrolled 282 cirrhotic patients who underwent CEUS at our institute, from January 2008 to January 2012, for focal liver lesions (FLLs) detected at ultrasound (US). We used liver biopsy and subsequent histological evaluation as the gold standard for correct classification of FLLs. We calculated the area under receiver operator characteristic curves for CEUS to distinguish patients with HCC from those with non-HCC malignancies. The best 'time to wash-out' cut-off values were selected. RESULTS: HISTOLOGICAL DIAGNOSIS OF FLLS WAS AS FOLLOWS: 34 benign lesions (i.e. 25 regenerative nodules and 9 dysplastic nodules) and 248 malignant lesions (223 well-to-moderately differentiated HCCs; 7 poorly-differentiated HCCs; 5 intrahepatic colangiocellular carcinomas (ICCs); 5 primary non-Hodgkin B-cell lymphomas (NHBLs); and 8 metastatic liver tumors). A time to wash-out > 55 s identified patients with HCC with the highest level of accuracy (92.7%). Similarly, a time to wash-out ≤ 55 s correctly identified the vast majority of the non-HCC malignancies (100% sensitivity, 98.2% specificity and diagnostic accuracy of 98.3%). CONCLUSIONS: CEUS is an accurate and safe procedure for discriminating FLLs in cirrhotic patients, especially when a cut-off time to wash-out of 55 s is chosen as a reference value.

Liver failure in an obese middle-aged woman after biliointestinal bypass.

Obesity is considered an emerging epidemic that is often associated with non-alcoholic fatty liver disease. Among the therapeutic options for morbid obesity, bariatric surgery plays an important role when conventional therapies fail. The effects of bariatric surgery on liver function and morphology are controversial in the literature. Liver failure has been reported after jejunoileal bypass (JIB), biliopancreatic diversion and gastric bypass. Biliointestinal bypass (BIB) is considered an effective procedure among recently introduced bariatric surgery techniques. It is a clinically safe, purely malabsorptive operation in which the blind intestinal loop of the JIB is anastomosed to the gallbladder, allowing a portion of bile to transit into excluded intestinal tract. BIB is the only procedure, to our knowledge, to have no liver side effects reported in the literature. We report the case of a young obese woman who developed liver failure 8 mo after BIB. She had a rapid weight loss (70 kg) with a reduction in body mass index of 41% from January to September 2012. Because of a severe hepatic decompensation, she was referred to a transplantation centre. We strongly believe that the most important pathogenetic mechanism involved in the development of liver injury is the rapid weight loss that produced a significant fatty liver infiltration.

Comparing the performance of the standard EQ-5D 3L with the new version EQ-5D 5L in patients with chronic hepatic diseases.

PURPOSE: To assess the performance of the EQ-5D-5L version compared with the standard EQ-5D-3L in a clinical setting targeted at patients with chronic hepatic diseases (CHDs). METHODS: We introduced the 5L descriptive system into a cost-of-illness study involving patients with different CHDs. The patients completed a questionnaire including the two versions of the EQ-5D, together with other questions related to their condition. We tested the feasibility, the level of inconsistency, the redistribution properties among consistent responses, the ceiling effect, the discriminative power, and the convergent validity of the 5L compared with the 3L system. RESULTS: A total of 1,088 valid patients were recruited: 62% male, 19-89 (median = 59) years old. Patients had chronic hepatitis from HCV (31.8%) or HBV infections (29.3%) or other causes (7.8%), 20.4% had cirrhosis, 11.9% underwent liver transplantation, and 7.8% had hepatic carcinoma. Less than 1% of EQ-5D-5L were returned blank, and 1.6% or less of missing values were calculated on the dimensions of the partially completed questionnaires. The proportion and weight of inconsistent responses (i.e., 3L responses that were at least two levels away from the 5L responses) was 2.9% and 1.2 on average, respectively. Regarding redistribution, 57-65% of the patients answering level 2 with the 3L version redistributed their responses to levels 2 or 4 with the 5L version. A relative 7% reduction of the ceiling effect was found. Furthermore, the absolute informativity increased but the relative informativity slightly decreased in every domain, and the convergent validity with the VAS improved. CONCLUSIONS: In a clinical setting involving CHD patients, the EQ-5D-5L was shown to be feasible and with promising levels of performance. Our findings suggest that the 5L performs better in at least some of the properties analyzed, and encourage further research to also test other psychometric properties of this new version of the EQ-5D.

Herbal products: benefits, limits, and applications in chronic liver disease.

Complementary and alternative medicine soughts and encompasses a wide range of approaches; its use begun in ancient China at the time of Xia dynasty and in India during the Vedic period, but thanks to its long-lasting curative effect, easy availability, natural way of healing, and poor side-effects it is gaining importance throughout the world in clinical practice. We conducted a review describing the effects and the limits of using herbal products in chronic liver disease, focusing our attention on those most known, such as quercetin or curcumin. We tried to describe their pharmacokinetics, biological properties, and their beneficial effects (as antioxidant role) in metabolic, alcoholic, and viral hepatitis (considering that oxidative stress is the common pathway of chronic liver diseases of different etiology). The main limit of applicability of CAM comes from the lacking of randomized, placebo-controlled clinical trials giving a real proof of efficacy of those products, so that anecdotal success and personal experience are frequently the driving force for acceptance of CAM in the population.

El papel de las hormonas intestinales en el control de la ingesta alimentaria: su función en enfermedades incipientes / The role of gut hormones in controlling the food intake. What is their role in emerging diseases?

El sistema nervioso central (SNC) recibe cierta información periférica capaz de regular el equilibrio energético del individuo a través de señales metabólicas, neuronales y endocrinas. Los nutrientes ingeridos entran en contacto con varios sitios del tracto gastrointestinal que son capaces de alterar las señales nerviosas y pépticas. Existe una fuerte relación entre el sistema nervioso central y estas señales periféricas (hormonas gastrointestinales) en el control de la ingesta de alimentos. El objetivo de esta revisión es aportar información actualizada sobre el papel de las hormonas intestinales como mediadoras de la conducta alimentaria, y de los diversos nutrientes que modulan la producción de hormonas intestinales. También se analiza el papel de las hormonas intestinales en la patogénesis de enfermedades incipientes tales como la obesidad y la esteatohepatitis no alcohólica (EHNA), así como la posibilidad de que estas señales periféricas sean dianas en futuras alternativas terapéuticas (AU)

Central nervous system (CNS) receives peripheral relevant information that are able to regulate individual's energy balance through metabolic, neural, and endocrine signals. Ingested nutrients come into contact with multiple sites in the gastrointestinal tract that have the potential to alter peptide and neural signaling. There is a strong relationship between CNS and those peripheral signals (as gastrointestinal hormones) in the control of food intake. The purpose of this review is to give updated information about the role of gut hormones as mediators of feeding behavior and of different nutrients in modulating gut hormones production. The role of gut hormones in the pathogenesis of emerging diseases as obesity and non-alcoholic fatty liver disease (NAFLD) is also discussed together with the possible role of these peripheral signals as targets of future therapeutic options (AU)

Gut microbiota and probiotics in chronic liver diseases.

There is a strong relationship between liver and gut: the portal system receives blood from the gut, and intestinal blood content activates liver functions. The liver, in turn, affects intestinal functions through bile secretion into the intestinal lumen. Alterations of intestinal microbiota seem to play an important role in induction and promotion of liver damage progression, in addition to direct injury resulting from different causal agents. Bacterial overgrowth, immune dysfunction, alteration of the luminal factors, and altered intestinal permeability are all involved in the pathogenesis of complications of liver cirrhosis, such as infections, hepatic encephalopathy, spontaneous bacterial peritonitis, and renal failure. Probiotics have been suggested as a useful integrative treatment of different types of chronic liver damage, for their ability to augment intestinal barrier function and prevent bacterial translocation. This review summarizes the main literature findings about the relationships between gut microbiota and chronic liver disease, both in the pathogenesis and in the treatment by probiotics of the liver damage.
