    Abstract Stem cells (SCs) are the key to tissue genesis and regeneration. Given their central role in homeostasis, dysfunctions of the SC compartment play a pivotal role in the development of cancers, degenerative disorders, chronic inflammatory pathologies and organ failure. The gastrointestinal tract is constantly exposed to harsh mechanical and chemical conditions and most of the epithelial cells are replaced every 3 to 5 d. According to the so-called Unitarian hypothesis, this renewal is driven by a common intestinal stem cell (ISC) residing within the crypt base at the origin of the crypt-to-villus hierarchical migratory pattern. Celiac disease (CD) can be defined as a chronic immune-mediated disease that is triggered and maintained by dietary proteins (gluten) in genetically predisposed individuals. Many advances have been achieved over the last years in understanding of the pathogenic interactions among genetic, immunological and environmental factors in CD, with a particular emphasis on intestinal barrier and gut microbiota. Conversely, little is known about ISC modulation and deregulation in active celiac disease and upon a gluten-free diet. Nonetheless, bone marrow-derived SC transplantation has become an option for celiac patients with complicated or refractory disease. This manuscript summarizes the "state of the art" regarding CD and ISCs, their niche and potential role in the development and treatment of the disease.

    Abstract The recent advancements in stem cell (SC) biology have led to the concept of regenerative medicine, which is based on the potential of SC for therapies aimed to facilitate the repair of degenerating or injured tissues. Nonetheless, prior to large scale clinical applications, critical aspects need to be further addressed, including the long-term safety, tolerability, and efficacy of SC-based treatments. Most problematic among the risks of SC-based therapies, in addition to the possible rejection or loss of function of the infused cells, is their potential neoplastic transformation. Indeed, SCs may be used to cure devastating diseases, but their specific properties of self-renewal and clonogenicity may render them prone to generate cancers. In this respect, 'Stemness' might be seen as a two-edged sword, its bright side being represented by normal SCs, its dark side by cancer SCs. A better understanding of SC biology will help fulfill the promise of regenerative medicine aimed at curing human pathologies and fighting cancer from its roots.

    Abstract Background: CPFA is an extracorporeal treatment used in severe sepsis to remove circulating proinflammatory cytokines. Limited evidence exists on the effectiveness of bilirubin adsorption by the hydrophobic styrenic resin, the distinctive part of CPFA. The aim of this study is to validate CPFA effectiveness in liver detoxification.
    Methods: In this prospective observational study, we enrolled patients with acute or acute-on-chronic liver failure (serum total bilirubin > 20 mg/dL or MELD Score > 20) hospitalized from June 2013 to November 2017. CPFA was performed using the Lynda (Bellco/MedTronic, Mirandola, Italy) or the Amplya (Bellco/MedTronic, Mirandola, Italy) machines. Anticoagulation was provided with unfractionated heparin or citrate. Bilirubin and bile acids reduction ratios per session (RRs) were the main parameters for hepatic detoxification.
    Results: Twelve patients with acute (n = 3) or acute-on-chronic (n = 9) liver failure were enrolled. Alcohol was the main cause of liver disease. Thirty-one CPFA treatments of 6 h each were performed, 19 with heparin and 12 with citrate. RRs was 28.8% (range 2.2-40.5) for total bilirubin, 32.7% (range 8.3-48.9) for direct bilirubin, 29.5% (range 6.5-65.4) for indirect bilirubin and 28.9% (16.7- 59.7) for bile acids. One patient received liver transplantation and 8/9 were alive at 1 year of follow-up. Three patients (25%) died: 2 during hospitalization and 1 for a cardiac event at 4 months of follow up with restored liver function.
    Conclusions: CPFA resulted to be effective in liver detoxification. Thus, it may be considered as a "bridge technique" both to the liver transplant and to the recovery of the basal liver function.

    Abstract Obesity is the most common nutritional disorder in the Western world. Actually, 250 million adults are obese, and 500 million adults and 22 million children under 5 years of age are overweight. Obesity is a complex trait, depending upon interactions between multiple genes and the environment, but its recent rise and "epidemic proportions" are, above all, the consequences of dramatic changes in lifestyle, socioeconomic progress, and political and cultural trends. Eating behavior has strong extraphysiological determinants, being influenced by neuroendocrine, nutritional, environmental, and cognitive stimuli, able to modify the body weight set-point. Health care professionals should be concerned about obesity, because of the well-established relations between excess body weight and pathologies such as type II diabetes, hypertension, atherosclerosis, osteoarthritis, dyslipidemia, and cancer, which afflict more and more people in the Western world--sort of "well-being syndromes." An overview of modern Western diets--the American, Mediterranean, Atkins, and Zone diets--reveals the contradictions existing about the correct and healthy approach to human nutrition and suggests a "return to Nature." From the actual artificial nutrition systems, based on cereals, milk, and their products, irrespective of our genome and metabolic attitudes, a simple diet based on natural food can be an ally in health maintenance and restoration.

    Abstract Italy was the first European country hit by the COVID-19 pandemic and has the highest number of recorded COVID-19 deaths in Europe. This prospective cohort study of the correlates of the risk of death in COVID-19 patients was conducted at the Infectious Diseases and Intensive Care units of Luigi Sacco Hospital, Milan, Italy. The clinical characteristics of all the COVID-19 patients hospitalised in the early days of the epidemic (21 February -19 March 2020) were recorded upon admission, and the time-dependent probability of death was evaluated using the Kaplan-Meier method (censored as of 20 April 2020). Cox proportional hazard models were used to assess the factors independently associated with the risk of death. Forty-eight (20.6 %) of the 233 patients followed up for a median of 40 days (interquartile range 33-47) died during the follow-up. Most were males (69.1 %) and their median age was 61 years (IQR 50-72). The time-dependent probability of death was 19.7 % (95 % CI 14.6-24.9 %) 30 days after hospital admission. Age (adjusted hazard ratio [aHR] 2.08, 95 % CI 1.48-2.92 per ten years more) and obesity (aHR 3.04, 95 % CI 1.42-6.49) were independently associated with an increased risk of death, which was also associated with critical disease (aHR 8.26, 95 % CI 1.41-48.29), C-reactive protein levels (aHR 1.17, 95 % CI 1.02-1.35 per 50 mg/L more) and creatinine kinase levels above 185 U/L (aHR 2.58, 95 % CI 1.37-4.87) upon admission. Case-fatality rate of patients hospitalized with COVID-19 in the early days of the Italian epidemic was about 20 %. Our study adds evidence to the notion that older age, obesity and more advanced illness are factors associated to an increased risk of death among patients hospitalized with COVID-19.

    Abstract Aim: To evaluate if a single and/or combined (clinical, endoscopic and radiological) assessment could predict clinical outcomes in Crohn's disease (CD).
    Methods: We prospectively evaluated 57 CD cases who underwent both a colonoscopy and a CT-enterography (CTE). Harvey-Bradshaw Index (HBi), SES-CD (and/or Rutgeerts score) and the radiological disease activity were defined to stratify patients according to clinical, endoscopic and radiological disease activity respectively. Hospitalizations, surgery, therapeutic changes and deaths were evaluated up to 36 months (time 1) for 53 patients.
    Results: CTE and endoscopy agreed in stratifying disease activity in 47% of cases (k = -0.05; p = 0.694), CTE and HBi in 35% (k = 0.09; p = 0.08), endoscopy and HBi in 39% (k = 0.13; p = 0.03). Taken together, CTE, endoscopy and HBi agreed only in 18% of cases (k = 0.01; p = 0.41). Among the 11 cases with mucosal healing, only 3 (27%) showed transmural healing. Patients with endoscopic activity needed significantly more changes of therapy compared to patients with endoscopic remission (p = 0.02). Patients with higher transmural or clinical activity at baseline required significantly more hospitalizations (p < 0.01). Hospitalization rate decreases with an increase in the number of parameters indicating remissions at baseline (p = 0.04).
    Conclusions: Clinical, endoscopic and radiological assessments offer complementary information and could predict different mid-term outcomes in CD.
