Background: Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist approved for the treatment of Crohn's disease (CD). Only limited real-life data on the long-term outcomes of CD patients treated with UST are available. This study assessed UST's long-term effectiveness and safety in a large population-based cohort of moderate to severe CD patients. Methods: This was a multicenter, retrospective, observational cohort study that included both naïve and biologic-experienced patients treated with UST who achieved clinical remission or clinical response after at least one year of treatment. Clinical activity was scored according to the Harvey-Bradshaw Index (HBI). The primary endpoints were the maintenance or achievement of clinical remission after a further 12-month period of treatment, defined as an HBI of ≤5, and safety. Other endpoints included steroid-free remission, mucosal healing (MH), steroid discontinuation, and the need for treatment optimization during the follow-up. Results: Out of 562 CD patients, after an overall 24-month follow-up, clinical remission was present in 450 (80.0%) patients, and at 12 months, clinical remission was observed in 417/437 (95.4%) patients; 33/125 (26.4%) showed clinical response at 12 months ( p = 0.000). A total of 38/103 (36.9%) patients achieved MH. Only 2.1% (12/562), 3% (17/562), and 1.1% (6/562) of patients required surgery, optimization, and re-induction, respectively. Adverse events occurred in eight patients (1.42%). According to a multivariate analysis, the only predictor of long-term remission was the presence of remission at the 12-month follow-up ( p = 0.000). Conclusions : Long-term treatment with UST presents good efficacy and safety profiles in CD patients, especially for patients who achieve remission after one year.

Background: Psilocybin-assisted psychotherapy (PAP) has been associated with antidepressant effects. Trials to date have typically excluded participants with complex presentations. Our aim was to determine the feasibility of PAP in a complex population, including high levels of treatment resistance in major depressive and bipolar disorder and patients with baseline suicidality and significant comorbidity. We also evaluated flexible repeated doses over a 6-month period., Methods: Adults with treatment-resistant depression as part of major depressive or bipolar II disorder without psychosis or a substance use disorder were eligible to participate. Subjects were randomized to immediate treatment or waitlist control, with all eventually receiving PAP. Participants had one, two, or three psilocybin sessions with a fixed dose of 25 mg. Each dose was accompanied by preparation and integration psychotherapy sessions. Acceptability, safety, tolerability, and efficacy were evaluated (this study was registered at ClinicalTrials.gov: NCT05029466)., Findings: Participants were randomized to immediate treatment (n = 16) or delayed treatment (n = 14). 29/30 were retained to the week-2 primary endpoint. Adverse events were transient, with no serious adverse events. Greater reductions in depression severity as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) were observed in the immediate treatment arm compared to the waitlist period arm with a large hedge's g effect size of 1.07 (p < 0.01). Repeated doses were associated with further reductions in MADRS scores compared to baseline., Conclusions: PAP was feasible in complex patients with preliminary antidepressant efficacy and adequate safety and tolerability. Repeated doses were associated with greater reductions in depression severity., Funding: This work was funded by Brain and Cognition Discovery Foundation (BCDF), Usona, and Braxia Scientific., Competing Interests: Declaration of interests J.D.R. has received research grant support from the Canadian Institute of Health Research (CIHR), Physician Services, Inc.

Background:  Texture and color enhancement imaging (TXI) was recently proposed as a substitute for standard high definition white-light imaging (WLI) to increase lesion detection during colonoscopy. This international, multicenter randomized trial assessed the efficacy of TXI in detection of colorectal neoplasia., Methods:  Consecutive patients aged ≥ 40 years undergoing screening, surveillance, or diagnostic colonoscopies at five centers (Italy, Germany, Japan) between September 2021 and May 2022 were enrolled. Patients were randomly assigned (1:1) to TXI or WLI. Primary outcome was adenoma detection rate (ADR). Secondary outcomes were adenomas per colonoscopy (APC) and withdrawal time. Relative risks (RRs) adjusted for age, sex, and colonoscopy indication were calculated., Results:  We enrolled 747 patients (mean age 62.3 [SD 9.5] years, 50.2 % male). ADR was significantly higher with TXI (221/375, 58.9 %) vs. WLI (159/372, 42.7 %; adjusted RR 1.38 [95 %CI 1.20-1.59]). This was significant for ≤ 5 mm (RR 1.42 [1.16-1.73]) and 6-9 mm (RR 1.36 [1.01-1.83]) adenomas. A higher proportion of polypoid (151/375 [40.3 %] vs. 104/372 [28.0 %]; RR 1.43 [1.17-1.75]) and nonpolypoid (136/375 [36.3 %] vs. 102/372 [27.4 %]; RR 1.30 [1.05-1.61]) adenomas, and proximal (143/375 [38.1 %] vs. 111/372 [29.8 %]; RR 1.28 [1.05-1.57]) and distal (144/375 [38.4 %] vs. 98/372 [26.3 %]; RR 1.46 [1.18-1.80]) lesions were found with TXI. APC was higher with TXI (1.36 [SD 1.79] vs. 0.89 [SD 1.35]; incident rate ratio 1.53 [1.25-1.88])., Conclusions:  TXI increased ADR and APC among patients undergoing colonoscopy for various indications. TXI increased detection of polyps < 10 mm, both in the proximal and distal colon, and may help to improve colonoscopy quality indicators., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Orthopaedics needs a robust diagnostic tool that can help or even replace traditional radiography in bone healing assessment, thus reducing patient exposure to ionizing radiation. We used a vibrational method to assess the healing of a complex fracture treated with external fixation, exploiting a quantitative and non-invasive procedure. Callus stiffening was monitored from the time of surgery until the fixator was removed. Our approach overcomes previous limitations and involves a longer period of healing monitoring (about 9 months), very frequent tests (bi-weekly), and the analysis of a single test configuration. The healing process was monitored by analysing the percentage increments of the squared resonant frequencies (SFIs), related to the stiffness variation and the changes in the frequency response functions. The results were validated by X-rays images, and revealed that the most sensitive parameter to quantify the healing was the SFI of the first resonant frequency which increased by about 20% per month during the formation of the woven callus and up to about 50% at the end of healing completion. This study confirms the potential of the vibrational method as an alternative to radiography in fracture healing assessment.

Background: A validated endoscopic classification of diverticular disease (DD) of the colon is lacking at present. Our aim was to develop a simple endoscopic score of DD: the Diverticular Inflammation and Complication Assessment (DICA) score., Methods: The DICA score for DD resulted in the sum of the scores for the extension of diverticulosis, the number of diverticula per region, the presence and type of inflammation, and the presence and type of complications: DICA 1 (≤ 3), DICA 2 (4-7) and DICA 3 (>7). A comparison with abdominal pain and inflammatory marker expression was also performed. A total of 50 videos of DD patients were reassessed in order to investigate the predictive role of DICA on the outcome of the disease., Results: Overall agreement in using DICA was 0.847 (95% confidence interval, CI, 0.812-0.893): 0.878 (95% CI 0.832-0.895) for DICA 1, 0.765 (95% CI 0.735-0.786) for DICA 2 and 0.891 (95% CI 0.845-0.7923) for DICA 3. Intra-observer agreement (kappa) was 0.91 (95% CI 0.886-0.947). A significant correlation was found between the DICA score and C-reactive protein values (p = 0.0001), as well as between the median pain score and the DICA score (p = 0.0001). With respect to the 50 patients retrospectively reassessed, occurrence/recurrence of disease complications was recorded in 29 patients (58%): 10 (34.5%) were classified as DICA 1 and 19 (65.5%) as DICA 2 (p = 0.036)., Conclusions: The DICA score is a simple, reproducible, validated and easy-to-use endoscopic scoring system for DD of the colon., (© 2014 S.

Hepatitis B virus (HBV) infection affects a large part of the world population. Within the different virological HBV categories that have been identified, patients with occult HBV infection represent a peculiar group. These individuals harbor a replication competent virus, inhibited in its replicative function. Accordingly, cases of reactivations have been observed in immunosuppressed individuals who lose immunological control over the infection. Patients with hematological malignancies (HM) are treated with intense myelo- and immunosuppressive chemotherapy regimens which favor HBV reactivation. This event can have severe consequences, such as hepatitis flare, hepatic failure and even death. In addition, it can lead to delays or interruptions of curative treatments, resulting in a decreased disease free and overall survival. In this review, we will examine the event of HBV reactivation in patients with signs of resolved HBV infection undergoing treatment for HM and propose possible management strategies.

We describe a case of severe acute hepatitis B developing in a patient with Hodgkin's lymphoma after chemotherapy and before radiotherapy. Entecavir was administered leading to virological and biochemical response, which allowed the scheduled treatment to be completed. The patient had complete haematological remission and made a complete recovery from hepatitis B.

Background: Rituximab has provided a revolutionary contribution to the treatment of B-cell non-Hodgkin's lymphomas (NHL). A high prevalence of hepatitis C virus (HCV) infection has been described in B-cell NHL patients. Cases of liver dysfunction in HCV-positive patients have been reported with rituximab-containing regimens., Aim: to evaluate the liver-related effects of rituximab-containing regimens on HCV-positive CD20-positive B-cell NHL patients., Patients and Methods: Retrospective analysis of 104 consecutive patients. HCV status was determined, and development of hepatitis flares analysed., Results: Nine patients (8.6%) were HCV-positive. No correlation was shown between viral load and alanine transaminase levels. Three of the 9 HCV-positive, and none of the 95 HCV-negative developed hepatitis flares (p<0.001). At the 12-month follow-up hepatitis flare patients were alive and in remission for their haematological disease and no hepatitis flares, liver-related death had developed., Conclusions: HCV-positive status may represent a risk factor for the development of hepatic flares in B-cell NHL patients receiving rituximab-containing regimens. Despite the increase in liver function tests, there were no major clinical events., (Copyright © 2010 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.)

Patients with inactive or occult hepatitis B virus infection and onco-hematological malignancies are at risk of hepatitis flare, hepatic failure and death due to chemotherapy-mediated reactivation. Nucleot(s)ide analogues can reduce reactivation risks and/or hepatitis. However, immuno-mediated phenomena combine to determine liver damage and clinical outcome. We describe in this report two patients with onco-hematological malignancies and hepatitis B reactivation after chemotherapy in whom glucocorticoids were added to nucleot(s)ide. Antiviral therapy was effective on replication, while glucocorticoids managed hyperergic response. One patient without underlying liver disease survived, while the second died and the autopsy demonstrated cirrhosis undetected before death. This clinical trial suggests that in patients with onco-hematological malignancies and altered liver function tests in spite of effective antiviral response, glucocorticoids could control the effects of immune response. However prognosis and survival are related to the underlying liver status.

Background: Use of herbal remedies (HR) has increased in the general population, particularly among patients with chronic diseases. Marketing of HR is usually regulated by imperfect standards, and the reporting of HR-related adverse reactions has increased. Studies assessing prevalence of HR use among patients with liver/biliary tract disorders are limited and no data are available in Italy. Aims of this study were to assess the prevalence of HR use, the clinical and demographic variables of HR users, and to evaluate their safety perception about HR., Study: From October 1, 2007 to April 30, 2008, 231 consecutive patients attending the Liver Disease Unit clinic at Sant'Andrea Hospital, II Faculty of Medicine "La Sapienza" Rome, were interviewed using an ad hoc developed questionnaire. The questionnaire addressed the following items: demographic and clinical characteristics, use of conventional therapy, use of HR and safety perception. Data were expressed as mean (+/-SD) or number/total, and evaluated by student t and chi2 tests; univariate analysis and multivariate logistic regression (MLR) were conducted., Results: Prevalence of HR use was 35.5%. HR use was more common among women (P=0.01), and in patients attending sports activity (P=0.03). 72% of patients using HR had never considered potentially harmful HR-side effects or interactions. Sixty-seven percent used HR in addition to conventional therapy., Conclusions: More than a third of patients attending Liver/Biliary Disorders Clinic uses HR. Misconceptions about HR safety is common.

Background: Knowledge of factors able to predict the clinical outcome of homogenous series of entero-pancreatic endocrine tumours treated with somatostatin analogues is poor. This study was aimed at identifying predictors for efficacy of somatostatin analogues at inhibiting tumour growth and modifying patients' survival during long-term follow-up., Patients and Methods: 31 patients with entero-pancreatic well-differentiated endocrine carcinoma received long-acting somatostatin analogues. All had progressive, metastatic disease (87% liver metastases, 38.7% distant extra-hepatic metastases)., Results: Response rate after 6 months of treatment was 45.2% (all disease stabilisation: 27.8% of pancreatic vs. 81.8% of intestinal tumours, P = 0.007). The predictors for non-response were: pancreatic tumour (OR 5.8), no previous surgery (OR 6.7), and the presence of distant extra-hepatic metastases, the latter being also confirmed by multivariate analysis (OR 10.0). Responders maintained stabilisation for 26.5 months, and none died during follow-up. Different survival curves were observed for patients, responding at 6 months compared to non-responders (P = 0.004), 3-year survival rate being 100% and 52.3%, respectively., Conclusions: Distant extra-hepatic metastases are the major predictor of poor efficacy of somatostatin analogues in progressive, metastatic, well-differentiated entero-pancreatic endocrine carcinomas. Patients achieving response after 6 months of treatment, maintain it throughout a long-term follow-up. Non-responders after 6 months of treatment, have a worse survival, and should be considered for alternative treatments.

Since gastro-entero-pancreatic endocrine tumors are rare and heterogeneous diseases, their prognosis and long-term survival are not well known. This study aimed at identifying prognostic factors and assessing long-term survival in gastro-entero-pancreatic endocrine tumors. A total of 156 patients enrolled. Prognostic factors were determined by univariate/multivariate analysis; survival rates were assessed by the Kaplan-Meier method. The tumors were non-functioning in 59.6% of patients, and originated from the pancreas in 42.9%. At diagnosis, 64.3% of patients had metastases. The tumors were well differentiated in 89.6% of patients. Ki67 was >2% in 39.6% of patients. Primary tumor size was >3 cm in 49.6% of cases studied. For the univariate analysis, the negative prognostic factors were: pancreatic origin (rate ratio 4.64, P = 0.0002), poorly differentiated tumor (rate ratio 7.70, P = 0.0001), primary tumor size >3 cm (rate ratio 4.26, P = 0.0009), presence of distant metastases (liver: rate ratio 5.88, P = 0.01; distant extra-hepatic: rate ratio 13.41, P = 0.0008). The pancreatic site, the poor degree of differentiation and the distant metastases were confirmed as negative prognostic factors at multivariate analysis. Overall 5-year survival rate was 77.5%. Survival rates differed according to: primary tumor site (62% for pancreatic vs 89.9% for gastrointestinal tract, P = 0.0001) and size (65.7% for >3 cm vs 88.8% for < or = 3 cm, P = 0.0003), degree of differentiation (22% for poor vs 86.8% for good, P < 0.0001), Ki67 (53.5% for > 2% vs 90.1% for < or = 2%, P = 0.003), metastases (96.1, 77, 73.3 and 50.1% for absent, local, liver and distant extra-hepatic metastases respectively), age at diagnosis (85.3% for < or = 50 years vs 70.3% for > 50 years, P = 0.03). Although 64.3% of gastro-entero-pancreatic endocrine tumors present metastases at diagnosis, the 5-year survival rate is 77.5%. Pancreatic site, a poor degree of tumor cell differentiation and distant extra-hepatic metastases are the major negative prognostic factors.
