Abstract
Since the rise of awareness of gluten/wheat-related disorders in the academic and clinical field in the last few decades, misinformation regarding the gluten-free diet (GFD) and its impact on health has been spreading among the general population. Despite the established link between gluten and celiac disease (CD), where a GFD is mandatory to reach clinical and histological remission, things are more complicated when it comes to non-celiac gluten/wheat sensitivity (NCGWS) and other autoimmune/dysimmune disorders. In the last conditions, a beneficial effect of gluten withdrawal has not been properly assessed, but still is often suggested without strong supporting evidence. In this context, women have always been exposed, more than men, to higher social pressure related to nutritional behaviors and greater engagement in controlling body weight. With this narrative review, we aim to summarize current evidence on the adherence to a GFD, with particular attention to the impact on women's health.

Abstract
Background Chronic constipation (CC) is a severe symptom in Parkinson's disease (PD), with an unclear pathogenesis. Abnormalities of the enteric nervous system (ENS) and/or intestinal epithelial barrier (IEB) may be pathophysiologically relevant in PD patients with CC. We investigated possible molecular changes of the IEB in PD/CCs compared with CCs and controls. Methods Twelve PD/CCs (2 female, age range 51-80 years), 20 CCs (15 female, age range 27-78 years), and 23 controls (11 female, age range 32-74 years) were enrolled. Ten PD/CCs and 10 CCs were functionally characterized by anorectal manometry (AM) and transit time (TT). Colon biopsies were obtained and assessed for gene and protein expression, and localization of IEB tight junction markers claudin-4 (CLDN4), occludin-1 (OCCL-1), and zonula occludens-1 (ZO-1) by RT-qPCR, immunoblot and immunofluorescence labeling. Results PD/CCs were clustered in 2 functional categories: patients with delayed TT and altered AM (60%), and a second group showing only modifications in AM pattern (40%). Gene expression of CLDN4, OCCL-1 and ZO-1 was higher in PD/CCs than controls (P<0.05). Conversely, PD/CCs showed a trend to decrease (P>0.05) in CLDN4 and OCCL-1 protein levels than controls, whereas ZO-1 protein was comparable. In PD/CCs compared with controls, decreasing tendency of vasoactive intestinal polypeptide mRNA, protein and immunoreactive fiber density were observed, although the difference was not statistically significant. Conclusion Transit and anorectal dysfunctions in PD/CCs are associated with difference in ZO-1, OCCL-1 and CLDN4 expression, thus supporting the role of an altered IEB as a contributory mechanism to possible neuronal abnormalities.

Abstract
BACKGROUND Life expectancy and the number of ultra-octogenarians increased significantly, thus making crucial the appropriateness of several endoscopic procedures in elderly patients. The aim of our study was to provide a retrospective analysis of the efficacy and safety of capsule endoscopy (CE) in patients aged over 80 years. METHODS In this single-centre study, 900 patients underwent capsule endoscopy between 2002 and 2015 for different indications; of these 106 patients aged ≥80 years (group A) and 99 patients aged 40-60 years (control group B) were retrospectively selected. RESULTS Occult gastrointestinal bleeding accounted for 62.1% of all indications for capsule endoscopy in group B, compared to 95.2% in group A (P<0.001). Although not statistically significant, the diagnostic yield was higher in group A (71%) vs. group B (62%). The percentages of reaching the cecum and the median gastric transit time were uniform within the two groups. In contrast, small bowel transit time was longer in group A vs. B. Small bowel preparation was similar in the two groups. The exam was generally well tolerated in both groups, with capsule aspiration being one of the main adverse events, which occurred in two elderly patients. CONCLUSIONS Our data expand previous findings confirming that capsule endoscopy can be performed safely even in very old patients and show that the diagnostic yield is similar to that of younger patients.

Abstract
Background: The post-delivery period could be characterized by psychological distress (e.g., anxiety, sadness, and irritability), leading to postpartum depression (PPD). Objective: The present clinical study assesses the effect of probiotic supplementation containing Limosilactobacillus reuteri PBS072 and Bifidobacterium breve BB077 (4 × 109 CFU/day) on the mother's mood and breastfeeding quality during the first trimester after delivery. Methods: A Randomized, Double-Blind, Controlled (RDBPC) trial was carried out on 200 healthy new mothers divided into an active group taking a supplement containing Limosilactobacillus reuteri PBS072 and Bifidobacterium breve BB077 (4 × 109 CFU/day) plus multivitamins and a control group (multivitamin complex only) for 90 days. Symptoms related to maternal depression and breastfeeding quality were evaluated at days 45 and 90 using the Edinburgh Postnatal Depression Scale (EPDS) and the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Results: At days 45 and 90, the probiotic treatment significantly ameliorated the mothers' mood compared to the control treatment (p < 0.001). Likewise, the breastfeeding quality and the baby's cries significantly improved in the probiotic group (p < 0.001). Conclusions: Microbiota alterations could influence a post-delivery woman's mental state. According to our results, L. reuteri PBS072 and B. breve BB077 are potential candidates that are able to improve stress resilience in the postpartum period.

Abstract
BACKGROUND Alcohol withdrawal syndrome (AWS) is characterized by different phases (acute, early and protracted). Protracted alcohol withdrawal (PAW) presents some symptoms, which may persist for several weeks, months or even years after drinking cessation. METHODS We conducted a systematic review of the literature in major scientific databases on selected AWS symptoms (craving, sleep disorders, and anhedonia) in patients with alcohol use disorder. RESULTS Of the 102 eligible publications (70 RCTs and 32 cohort studies), 88 provided data on craving, 21 on sleep disorders, and 1 on anhedonia. Overall, 37 studies assessed craving using the Obsessive Compulsive Drinking Scale (OCDS). Pooled OCDS decreased from 24.2 at baseline to 18.8 at 1 week, 10.3 at 1 month and 9.7 at 3 months. The corresponding estimates for treated individuals were 23.9, 18.8, 8.7, and 8.8, and for non-treated subjects, they were 25.3, 13.9, 13.2, and 11.4, respectively. In 4 studies assessing sleep disorders using the Epworth Sleeping Scale (ESS), the scale remained stable in time, i.e., 7.3 at baseline, 7.3 at 1 week, 7.2 at 1 month, and 7.1 at 3 months. CONCLUSION This study confirms the presence of PAW after the resolution of the acute phase of AWS. The pharmacological approach to managing PAW may ensure a more rapid reduction of symptoms in three weeks. We highlight the importance of studying PAW and the ability of pharmacological treatment to reduce its symptoms. This review protocol is registered in Prospero (registration number: CRD42020211265). SUMMARY This systematic review summarizes literature on major symptoms of protracted alcohol withdrawal in patients with alcohol use disorder. The pharmacological approach to manage protracted alcohol withdrawal ensures a more rapid reduction of symptoms (craving in particular), achieving in three weeks similar results obtained only after almost 6 months without treatment.

Abstract
BACKGROUND Coronavirus Disease 2019 (COVID-19), firstly reported in China last November 2019, became a global pandemic. It has been shown that periods of isolation may induce a spike in alcohol use disorder (AUD). In addition, alcohol-related liver disease (ALD) is the most common consequence of excessive alcohol consumption worldwide. Moreover, liver impairment has also been reported as a common manifestation of COVID-19. AIMS The aim of our position paper was to consider some critical issues regarding the management of ALD in patients with AUD in the era of COVID-19. METHODS A panel of experts of the Italian Society of Alcohology (SIA) met via "conference calls" during the lockdown period to draft the SIA's criteria for the management of ALD in patients with COVID-19 as follows: (a) liver injury in patients with ALD and COVID-19 infection; (b) toxicity to the liver of the drugs currently tested to treat COVID-19 and the pharmacological interaction between medications used to treat AUD and to treat COVID-19; (c) reorganization of the management of compensated and decompensated ALD and liver transplantation in the COVID-19 era. RESULTS AND CONCLUSIONS The COVID-19 pandemic has rapidly carried us toward a new governance scenario of AUD and ALD which necessarily requires an in-depth review of the management of these diseases with a new safe approach (management of out-patients and in-patients following new rules of safety, telemedicine, telehealth, call meetings with clinicians, nurses, patients, and caregivers) without losing the therapeutic efficacy of multidisciplinary treatment.

Abstract
Coronavirus disease 2019 (COVID‐19) first emerged in China in November 2019. Most governments have responded to the COVID‐19 pandemic by imposing a lockdown. Some evidence suggests that a period of isolation might have led to a spike in alcohol misuse, and in the case of patients with alcohol use disorder (AUD), social isolation can favour lapse and relapse. The aim of our position paper is to provide specialists in the alcohol addiction field, in psychopharmacology, gastroenterology and in internal medicine, with appropriate tools to better manage patients with AUD and COVID‐19,considering some important topics: (a) the susceptibility of AUD patients to infection; (b) the pharmacological interaction between medications used to treat AUD and to treat COVID‐19; (c) the reorganization of the Centre for Alcohol Addiction Treatment for the management of AUD patients in the COVID‐19 era (group activities, telemedicine, outpatients treatment, alcohol‐related liver disease and liver transplantation, collecting samples); (d) AUD and SARS‐CoV‐2 vaccination. Telemedicine/telehealth will undoubtedly be useful/practical tools even though it remains at an elementary level; the contribution of the family and of caregivers in the management of AUD patients will play a significant role; the multidisciplinary intervention involving experts in the treatment of AUD with specialists in the treatment of COVID‐19 disease will need implementation. Thus, the COVID‐19 pandemic is rapidly leading addiction specialists towards a new governance scenario of AUD, which necessarily needs an in‐depth reconsideration, focusing attention on a safe approach in combination with the efficacy of treatment.

Abstract
Inflammatory bowel diseases (IBDs) are conditions characterized by persistent and relapsing inflammation involving the gastrointestinal tract at various levels. Although the etiopathogenesis of IBDs is partially understood, a deregulated activation of intestinal immune cells in genetically susceptible patients is thought to be key for the disease onset and evolution. Artificial Nutrition might affect favorably on inflammation and related cytokine storm. However, the discovery of monoclonal antibodies blocking pro-inflammatory cytokines (e.g., tumor necrosis factor-α - TNF-α) changed radically the management of IBDs. Anti-TNF-α agents represent the prototype molecule of the so-called 'biologics' / 'biologicals'. These compounds have significantly improved the therapeutic management of IBDs refractory to standard medications, achieving clinical remission, mucosal healing and preventing extra-intestinal manifestations. However, about 50% of patients treated with biologicals experienced drawbacks, such as primary failure or loss of response, requiring new effective treatments. Translational studies have identified other pathways, different from the TNF-α blockade, and new molecules, e.g. sphingosine-1-phosphate agonists and the JAK kinase inhibitors, have been proposed as potential therapeutic options for IBDs. These novel therapeutic approaches represent a "new era" of IBD management, especially for patients poorly responsive to biologicals. In this review, we will summarize the new pharmacological strategies to treat IBDs, and discuss their effectiveness and safety, along with future perspectives for IBD treatment.

Abstract
BACKGROUND Coeliac disease (CD) results from an immune-mediated reaction to gluten in genetically predisposed individuals. In rare cases CD may occur with acute features deferring the diagnosis and exposing these patients to possible life-threatening complications. Herein we present the case of a young woman with a coeliac crisis, that is, a sudden clinical onset characterised by severe electrolyte imbalance due to an unknown (previously unrecognised) CD. METHODS This is a case report and literature review revealing that coeliac crisis is under-reported, with a total of 48 adult cases so far published. The diagnosis in our case was established by histopathological analysis of multiple duodenal biopsies. The patient's serum was tested by enzyme-linked immunoassay to detect antitransglutaminase IgA antibodies. RESULTS In contrast to cases reported in the literature, with male gender predominance and a mean age of 50±17 years, our patient was a young female case of coeliac crisis. However, like in our patient, a higher incidence of coeliac crisis was associated with the human leucocyte antigen (HLA)-DQ2 haplotype, versus HLA-DQ8, and a severe (Marsh-Oberhüber 3c) duodenal mucosa atrophy. Notably, there is no clear correlation between the antitissue transglutaminase 2 IgA antibody titre and coeliac crisis onset/severity, as confirmed by our case report. CONCLUSIONS The present case highlights that CD may manifest quite abruptly with a severe malabsorption syndrome, that is, electrolyte abnormalities and hypoproteinaemia. Our case should alert physicians, in particular those in the emergency setting, that even a typically chronic disorder, such as CD, may show life-threatening complications requiring urgent management.

Abstract
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) which can affect any part of the whole gastrointestinal tract (from mouth to anus). Malnutrition affects 65-75% of CD patients, and it is now well acknowledged that diet is of paramount importance in the management of the disease. In this review, we would like to highlight the most recent findings in the field of nutrition for the treatment of CD. Our analysis will cover a wide range of topics, from the well-established diets to the new nutritional theories, along with the recent progress in emerging research fields, such as nutrigenomics.

Abstract
Inflammatory bowel diseases such as ulcerative colitis (UC) may be complicated by several extraintestinal manifestations. These involve joints, skin, eyes and less commonly lungs and heart. Myocarditis may result from the toxic effect of drugs (ie, mesalazine) commonly used for the treatment of UC or due to infections (eg, Coxsackieviruses, enteroviruses, adenovirus). Here, we report a case of a 26-year old man affected by UC and complicated by two episodes of myocarditis. Both episodes occurred during two severe exacerbations of UC. However, in both cases the aetiology of myocarditis remains uncertain being ascribable to extraintestinal manifestation, drug toxicity or both.

Abstract
OBJECTIVE Early identification of Harmful Drinking (HD) is difficult, and underestimated. The aim of our retrospective study was to investigate the presence of HD in a population of subjects who had their driving license suspended due to driving under the influence of alcohol. MATERIALS AND METHODS We retrospectively recruited 979 subjects. During the first appointment (T0), clinical and laboratory characteristics of patients were evaluated, and the AUDIT questionnaire was administered. Two groups were then defined: Harmful Drinking (HD) and non-HD, and all subjects underwent a brief interview for 5-10 minutes before being assigned to a group. RESULTS 95.9% of our sample were identified as non-HD, whereas 4.1% of them were HD; twenty-one (2.1%) of the HD underwent a control appointment (T1), and 17 (1.7%) of them were diagnosed with alcohol use disorder (AUD); there was a statistically significant reduction in mean daily alcohol intake (p<0.009), and in the mean values of the blood markers of HD between T0 and T1 in HD. CONCLUSIONS The present study shows that 4.1%, and 1.7% of subjects presented a diagnosis of HD and AUD, respectively, and their entry in a protocol of drinking monitoring proved beneficial in reducing alcohol intake. Thus, the implementation of strict surveillance of subjects found driving under the influence of alcohol involving a network of professional figures (from police forces to specialists in alcohol addiction treatment) may help to detect and to treat subjects with HD and AUD, and to monitor their alcohol use over time.

Abstract
Minimal lesions of the small bowel are mucosal changes characterized by an increased number of intraepithelial lymphocytes (with or without crypt hyperplasia) and normal villous architecture. Such changes are associated with a wide spectrum of conditions, ranging from food intolerances to infections, and from drugs to immune diseases, with different clinical profiles and manifestations, which complicates the formulation of a differential diagnosis. Patient history, symptom evaluation, and histopathology are the diagnostic features needed to establish a correct diagnosis. Physicians should assist pathologists in formulating a precise morphological evaluation by taking well-oriented small intestinal biopsies and collecting informative clinical findings that inform histopathology. In this current clinical controversy, the authors provide the reader with an appraisal of the small intestine minimal lesions through a careful analysis of the major conditions (e.g., celiac disease and other non-celiac disorders) responsible for such changes and their differential diagnosis. Also, we acknowledge that some of the diseases detailed in this article may progress from an early minimal lesion to overt mucosal atrophy. Thus, the timing of the diagnosis is of paramount importance.

Abstract
To date, the only available treatment for celiac disease (CD) patients is a life-lasting gluten-free diet (GFD). Lack of adherence to the GFD leads to a significant risk of adverse health consequences. Food cross-contamination, nutritional imbalances, and persistent gastrointestinal symptoms are the main concerns related to GFD. Moreover, despite rigid compliance to GFD, patients struggle in achieving a full restoring of the gut microbiota, which plays a role in the nutritive compounds processing, and absorption. Pivotal studies on the supplementation of GFD with probiotics, such as Bifidobacterium and Lactobacilli, reported a potential to restore gut microbiota composition and to pre-digest gluten in the intestinal lumen, reducing the inflammation associated with gluten intake, the intestinal permeability, and the cytokine and antibody production. These findings could explain an improvement in symptoms and quality of life in patients treated with GFD and probiotics. On the other hand, the inclusion of prebiotics in GFD could also be easy to administer and cost-effective as an adjunctive treatment for CD, having the power to stimulate the growth of potentially health-promoting bacteria strains. However, evidence regarding the use of prebiotics and probiotics in patients with CD is still insufficient to justify their use in clinical practice.

Abstract
The coronavirus disease (Covid-19) has caused a pandemic with more than 600,000 deaths to date. It is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the beta-coronavirus genus that also includes SARS and the Middle East Respiratory Syndrome Coronavirus (MERS). While the typical presentation is given by respiratory symptoms and fever, some patients also report gastrointestinal symptoms such as diarrhea, nausea, vomiting, and abdominal pain. Several studies have identified the SARS-CoV-2 RNA in stool specimens of infected patients, and its viral receptor angiotensin-converting enzyme 2 (ACE2) is highly expressed in enterocytes. In this short review, we report the frequency of gastrointestinal symptoms in infected patients and suggest possible implications for disease management, transmission, and infection control.

Abstract
The magnetization of mesenchymal stem cells (MSC) has the potential to aid tissue engineering approaches by allowing tracking, targeting, and local retention of cells at the site of tissue damage. Commonly used methods for magnetizing cells include optimizing uptake and retention of superparamagnetic iron oxide nanoparticles (SPIONs). These appear to have minimal detrimental effects on the use of MSC function as assessed by in vitro assays. The cellular content of magnetic nanoparticles (MNPs) will, however, decrease with cell proliferation and the longer-term effects on MSC function are not entirely clear. An alternative approach to magnetizing MSCs involves genetic modification by transfection with one or more genes derived from Magnetospirillum magneticum AMB-1, a magnetotactic bacterium that synthesizes single-magnetic domain crystals which are incorporated into magnetosomes. MSCs with either or mms6 and mmsF genes are followed by bio-assimilated synthesis of intracytoplasmic magnetic nanoparticles which can be imaged by magnetic resonance (MR) and which have no deleterious effects on MSC proliferation, migration, or differentiation. The stable transfection of magnetosome-associated genes in MSCs promotes assimilation of magnetic nanoparticle synthesis into mammalian cells with the potential to allow MR-based cell tracking and, through external or internal magnetic targeting approaches, enhanced site-specific retention of cells for tissue engineering.

Abstract
Bacterial pathogens that colonize wounds form biofilms, which protect the bacteria from the effect of host immune response and antibiotics. This study examined the effectiveness of newly synthesized zinc sulfide in inhibiting biofilm development by Staphylococcus aureus ( S. aureus) strains. Zinc sulfide (ZnS) was anaerobically biosynthesized to produce CompA, which was further processed by cryomilling to maximize the antibacterial properties to produce CompB. The effect of the two compounds on the S. aureus strain AH133 was compared using zone of inhibition assay. The compounds were formulated in a polyethylene glycol cream. We compared the effect of the two compounds on biofilm development by AH133 and two methicillin-resistant S. aureus clinical isolates using the in vitro model of wound infection. Zone of inhibition assay revealed that CompB is more effective than CompA. At 15 mg/application, the formulated cream of either compound inhibited biofilm development by AH133, which was confirmed using confocal laser scanning microscopy. At 20 mg/application, CompB inhibited biofilm development by the two methicillin-resistant S. aureus clinical isolates. To further validate the effectiveness of CompB, mice were treated using the murine model of wound infection. Colony forming cell assay and in vivo live imaging results strongly suggested the inhibition of S. aureus growth.

Abstract
The use of stem cells to support tissue repair is facilitated by loading of the therapeutic cells with magnetic nanoparticles (MNPs) enabling magnetic tracking and targeting. Current methods for magnetizing cells use artificial MNPs and have disadvantages of variable uptake, cellular cytotoxicity and loss of nanoparticles on cell division. Here we demonstrate a transgenic approach to magnetize human mesenchymal stem cells (MSCs). MSCs are genetically modified by transfection with the mms6 gene derived from Magnetospirillum magneticum AMB-1, a magnetotactic bacterium that synthesises single-magnetic domain crystals which are incorporated into magnetosomes. Following transfection of MSCs with the mms6 gene there is bio-assimilated synthesis of intracytoplasmic magnetic nanoparticles which can be imaged by MR and which have no deleterious effects on cell proliferation, migration or differentiation. The assimilation of magnetic nanoparticle synthesis into mammalian cells creates a real and compelling, cytocompatible, alternative to exogenous administration of MNPs.

Abstract
A versatile approach for the design and fabrication of multilayer magnetic scaffolds with tunable magnetic gradients is described. Multilayer magnetic gelatin membrane scaffolds with intrinsic magnetic gradients were designed to encapsulate magnetized bioagents under an externally applied magnetic field for use in magnetic-field-assisted tissue engineering. The temperature of the individual membranes increased up to 43.7 °C under an applied oscillating magnetic field for 70 s by magnetic hyperthermia, enabling the possibility of inducing a thermal gradient inside the final 3D multilayer magnetic scaffolds. On the basis of finite element method simulations, magnetic gelatin membranes with different concentrations of magnetic nanoparticles were assembled into 3D multilayered scaffolds. A magnetic-gradient-controlled distribution of magnetically labeled stem cells was demonstrated in vitro. This magnetic biomaterial-magnetic cell strategy can be expanded to a number of different magnetic biomaterials for various tissue engineering applications.

Abstract
Thermo switchable magnetic hydrogels undoubtedly have a great potential for medical applications since they can behave as smart carriers able to transport bioactive molecules to a chosen part of the body and release them on demand via magneto-thermal activation. We report on the ability to modify the lower critical solution temperature (LCST) of poly(N-isopropylacrylamide) (PNIPAM) on demand from 32 °C to LCST ≥ 37 °C. This was achieved by the absorption of controlled amounts of magnetite nanoparticles on the polymer chains. We show, through the effect on cell viability, that the resulting magnetic PNIPAM is able to trap and to release bio-active molecules, such as cell growth factors. The activities of the released bio molecule are tested on human umbilical vein endothelial cells culture. We demonstrate that the LCST of the magnetic PNIPAM can be reached remotely via inductive heating with an alternating magnetic field. This approach on magnetic PNIPAM clearly supports appealing applications in safe biomedicine.
