Flexibility is a key component of physical fitness. It has been suggested that measures of physical fitness components may vary throughout the day. The aim of this study was to analyse the effects of the time of day on flexibility performance. 26 men (mean age = 25.4 years, SD = 2.5) were evaluated by hip flexion on kinematic analysis and also by an absolute score in the modified Sit-and-Reach test during a repeated measure design. This was done during 3 experimental sessions, which took place at 8:00 a.m., 1:00 p.m. and 6:00 p.m., in random order. All subjects were previously familiarized with the test parameters. There was a diurnal variation only in the modified Sit-and-Reach test score between 8:00 a.m and 6:00 p.m. ( P = 0.01). There was no significant difference in the hip kinematic analysis between hours. These findings suggest that flexibility performance in the modified Sit-and-Reach test, in absolute scores, is affected by the time of day, with higher performance in the evening.

OBJECTIVE: It has been suggested that, in inflammatory bowel disease, cytomegalovirus behaves in the intestine as a nonpathogenic bystander, and even its finding in intestinal mucosa has unclear clinical relevance. We report our experience with a small series of patients with refractory inflammatory bowel disease and cytomegalovirus infection and their clinical outcome. METHODS AND RESULTS: Nine patients with moderate-severe attacks of inflammatory bowel disease did not respond to i.v. prednisone (I mg/kg/day) for a mean of 24 days. Four of these patients were further treated with i.v. cyclosporine A (4 mg/kg/day). Cytomegalovirus infection was diagnosed in two patients after resection for treatment failure. In the remaining patients, cytomegalovirus infection was diagnosed in endoscopic mucosal biopsies and i.v. ganciclovir was then administered at a dose of 10 mg/kg/day for 2-3 wk. Five of these patients went into clinical remission, allowing corticosteroid and cyclosporine A discontinuation. Follow-up biopsies were performed and in all cases cytomegalovirus could not be detected in the colonic tissue. Two patients needed to be treated with intravenous cyclosporine A after antiviral therapy because of persistence of clinical symptoms despite the elimination of cytomegalovirus infection. CONCLUSIONS: Cytomegalovirus infection may play a role in the natural history of refractory inflammatory bowel disease and in some of its complications. The clearance of cytomegalovirus in colonic mucosa may lead some of these patients to remission. [ABSTRACT FROM AUTHOR]

Objectives: Few studies have assessed the IgA antineutrophil cytoplasmic antibody (ANCA) positivity in ulcerative colitis patients and there is no information about factors related to its synthesis and its status after colectomy. The aims of the study were to assess the serum IgA ANCA prevalence in ulcerative colitis patients, both nonoperated and operated, and to determine the clinical factors related to this positivity. Methods: Fifty-four ulcerative colitis patients, 63 ulcerative colitis colectomized patients (32 with Brooke's ileostomy and 31 with ileal pouch anal anastomosis), and 24 controls were studied. Antineutrophil cytoplasmic antibodies were detected by specific indirect immunofluorescent assays. Results: The percentage of IgA ANCA was significantly higher in patients with ileal pouch anal anastomosis (45%) than in patients with Brooke's ileostomy (22%). There were no differences related to the presence of pouchitis in ileal pouch anal anastomosis patients. Patients with nonoperated extensive colitis (47%) had a significantly higher percentage of IgA ANCA than patients with proctitis (19%). Total percentage of ANCA (IgA and/or IgG) tended to be higher in ulcerative colitis and in patients with ileal pouch anal anastomosis than in patients with Brooke's ileostomy. However, in ileal pouch anal anastomosis patients, ANCA positivity was mainly due to exclusive IgA production. Conclusions: A substantial percentage of ulcerative colitis patients, and especially colectomized patients with ileal pouch anal anastomosis, had IgA ANCA, suggesting that ANCA production in ulcerative colitis might be stimulated by an immune reaction in the intestinal mucosa.

Background/Aim: Therapeutic regimens with intravenous (i.v.) cyclosporine followed by oral cyclosporine maintenance therapy reduce the need for immediate surgery in steroid-refractory severe ulcerative colitis, but the short-term colectomy rate is still as high as 70%. We report our experience with long-term azathioprine maintenance therapy in a small series of ulcerative colitis patients with i.v. cyclosporine-induced remission. Methods and Results: Twelve of thirteen patients with severe ulcerative colitis refractory to i.v. prednisone (1 mg/kg/day for at least 10 days) went into remission after adding i.v. cyclosporine (4 mg/kg/day) and are the subjects of this report. After a discouraging initial experience with oral cyclosporine plus mesalazine as maintenance therapy in the first four patients, we treated the following patients with azathioprine plus mesalazine starting immediately after response to i.v. cyclosporine was obtained. Overall, only 1 of 10 patients treated with azathioprine relapsed after a mean follow-up of 16.3 months (range: 6-48). Moreover, this relapse probably occurred when the drug was still not therapeutically active because, after reinducing remission with oral prednisone, the patient remained symptomless on azathioprine. Steroids could be discontinued in all patients. Conclusions: The relapse rate on maintenance therapy with azathioprine (10%) is a figure considerably lower than that previously reported with oral cyclosporine. This promising experience should be confirmed in ran-domized controlled trials. [ABSTRACT FROM AUTHOR]

- Abstract
Background and Aims: Crohn's disease [CD] is characterised by the expansion of mesenteric adipose tissue [MAT], named creeping fat [CF], which seems to be directly related to disease activity. Adipose-stem cells [ASCs] isolated from the CF of patients with CD are extremely pro-inflammatory, which persists during disease remission. We hypothesised that the dysfunctional ASCs in CD accumulate epigenetic modifications triggered by the inflammatory environment, that could serve as molecular markers., Methods: Genome-wide DNA methylome and transcriptome profiling were performed in ASCs isolated from MAT biopsies of patients with active and inactive disease and from non-Crohn's disease patients [non-CD]. A validation cohort was used to test the main candidate genes via quantitative polymerase chain reaction in other fat depots and immune cells., Results: We found differences in DNA methylation and gene expression between ASCs isolated from patients with CD and from non-CD subjects, but we found no differences related to disease activity. Pathway enrichment analysis revealed that oxidative stress and immune response were significantly enriched in active CD, and integration analysis identified MAB21L2, a cell fate-determining gene, as the most affected gene in CD. Validation analysis confirmed the elevated gene expression of MAB21L2 in MAT and in adipose tissue macrophages in active CD. We also found a strong association between expression of the calcium channel subunit gene CACNA1H and disease remission, as CACNA1H expression was higher in ASCs and MAT from patients with inactive CD, and correlates negatively with C-reactive protein in peripheral blood mononuclear cells., Conclusion: We identified a potential gene signature of CD in ASCs obtained from MAT. Integration analysis highlighted two novel genes demonstrating a negative correlation between promoter DNA methylation and transcription: one linked to ASCs in CD [MAB21L2] and the other [CACNA1H] related to disease remission., (© The Author(s) 2024.

- Abstract
Bilateral transcutaneous auricular vagus nerve stimulation (taVNS) - a non-invasive neuromodulation technique - has been investigated as a safe and feasible technique to treat many neuropsychiatric conditions. such as epilepsy, depression, anxiety, and chronic pain. Our aim is to investigate the effect of taVNS on neurophysiological processes during emotional and Go/No-Go tasks, and changes in frontal alpha asymmetry. We performed a randomized, double-blind, sham-controlled trial with 44 healthy individuals who were allocated into two groups (the active taVNS group and the sham taVNS group). Subjects received one session of taVNS (active or sham) for 60 min. QEEG was recorded before and after the interventions, and the subjects were assessed while exposed to emotional conditions with sad and happy facial expressions, followed by a Go/No-Go trial. The results demonstrated a significant increase in N2 amplitude in the No-Go condition for the active taVNS post-intervention compared to the sham taVNS after adjusting by handedness, mood, and fatigue levels (p = 0.046), significantly reduced ERD during sad conditions after treatment (p = 0.037), and increased frontal alpha asymmetry towards the right frontal hemisphere during the emotional task condition (p = 0.046). Finally, we observed an interesting neural signature in this study that suggests a bottom-up modulation from brainstem/subcortical to cortical areas as characterized by improved lateralization of alpha oscillations towards the frontal right hemisphere, and changes in ERP during emotional and Go/No-Go tasks that suggests a better subcortical response to the tasks. Such bottom-up effects may mediate some of the clinical effects of taVNS., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

- Abstract
Background: Ulcerative proctitis (UP) can have a milder, less aggressive course than left-sided colitis or extensive colitis. Therefore, immunosuppressants tend to be used less in patients with this condition. Evidence, however, is scarce because these patients are excluded from randomised controlled clinical trials. Our aim was to describe the characteristics of patients with refractory UP and their disease-related complications, and to identify the need for immunosuppressive therapies., Methods: We identified patients with UP from the prospective ENEIDA registry sponsored by the GETECCU. We evaluated socio-demographic data and complications associated with immunosuppression. We defined immunosuppression as the use of immunomodulators, biologics and/or small molecules. We used logistic regression to identify factors associated with immunosuppressive therapy., Results: From a total of 34,716 patients with ulcerative colitis, we identified 6281 (18.1%) with UP; mean ± SD age 53 ± 15 years, average disease duration of 12 ± 9 years. Immunosuppression was prescribed in 11% of patients, 4.2% needed one biologic agent and 1% needed two; 2% of patients required hospitalisation, and 0.5% underwent panproctocolectomy or subtotal colectomy. We identified 0.2% colorectal tumours and 5% extracolonic tumours. Patients with polyarthritis (OR 3.56, 95% CI 1.86-6.69; p < 0.001) required immunosuppressants., Conclusions: Among patients with refractory UP, 11% required immunosuppressant therapy, and 4.2% required at least one biologic agent., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Chronic pain is one of the major causes of disability with a tremendous impact on an individual's quality of life and on public health. Transcutaneous vagus nerve stimulation (tVNS) is a safe therapeutic for this condition. We aimed to evaluate its effects in adults with chronic pain. A comprehensive search was performed, including randomized controlled trials published until October 2023, which assessed the effects of noninvasive tVNS. Cohen's d effect size and 95% confidence intervals (CIs) were calculated, and random-effects meta-analyses were performed. Fifteen studies were included. The results revealed a mean effect size of 0.41 (95% CI 0.17-0.66) in favor of tVNS as compared with control, although a significant heterogeneity was observed (χ
2 = 21.7, df = 10, P = 0.02, I2 = 53.9%). However, when compared with nonactive controls, tVNS shows a larger effect size (0.79, 95% CI 0.25-1.33), although the number of studies was small (n = 3). When analyzed separately, auricular tVNS and cervical tVNS against control, it shows a significant small to moderate effect size, similar to that of the main analysis, respectively, 0.42 (95% CI 0.08-0.76, 8 studies) and 0.36 (95% CI 0.01-0.70, 3 studies). No differences were observed in the number of migraine days for the trials on migraine. This meta-analysis indicates that tVNS shows promise as an effective intervention for managing pain intensity in chronic pain conditions. We discuss the design of future trials to confirm these preliminary results, including sample size and parameters of stimulation., Competing Interests: H. Choi and J.-J. Song are directly associated with Neurive Co, a company developing neuromodulation technologies, such as taVNS, to treat common brain diseases. F.

- Abstract
Background: The multifaceted nature of Fibromyalgia syndrome (FM) symptoms has been explored through clusters analysis., Objective: To synthesize the cluster research on FM (variables, methods, patient subgroups, and evaluation metrics)., Methods: We performed a systematic review following the PRISMA recommendations. Independent searches were performed on PubMed, Embase, Web of Science, and Cochrane Central, employing the terms "fibromyalgia" and "cluster analysis". We included studies dated to January 2024, using the cluster analysis to assess any physical, psychological, clinical, or biomedical variables in FM subjects, and descriptively synthesized the studies in terms of design, cluster method, and resulting patient profiles., Results: We included 39 studies. Most with a cross-sectional design aiming to classify subsets based on the severity, adjustment, symptomatic manifestations, psychological profiles, and response to treatment, based on demographic and clinical variables. Two to four different profiles were found according to the levels of severity and adjustment to FMS. According to symptom manifestation, two to three clusters described the predominance of pain versus fatigue, and thermal pain sensitivity (less versus more sensitive). Other clusters revealed profiles of personality (pathological versus non-pathological) and psychological vulnerability (suicidal ideation). Additionally, studies identified different responses to treatment (pharmacological and multimodal)., Conclusion: Several profiles exist within FMS population, which point out to the need for specific treatment options given the different profiles and an efficient allocation of healthcare resources. We notice a need towards more objective measures, and the validation of the cluster results. Further research might investigate some of the assumptions of these findings, which are further discussed in this paper., (© 2024.

- Abstract
Patients with Crohn's disease (CD) who smoke are known to have a worse prognosis than never-smokers and a higher risk for post-surgical recurrence, whereas patients who quit smoking after surgery have significantly lower post-operative recurrence. The hypothesis was that smoking induces epigenetic changes that impair the capacity of adipose stem cells (ASCs) to suppress the immune system. It was also questioned whether this impairment remains in ex-smokers with CD. ASCs were isolated from non-smokers, smokers and ex-smokers with CD and their interactions with immune cells were studied. The ASCs from both smokers and ex-smokers promoted macrophage polarization to an M1 pro-inflammatory phenotype, were not able to inhibit T- and B-cell proliferation in vitro and enhanced the gene and protein expression of inflammatory markers including interleukin-1b. Genome-wide epigenetic analysis using two different bioinformatic approaches revealed significant changes in the methylation patterns of genes that are critical for wound healing, immune and metabolic response and p53-mediated DNA damage response in ASCs from smokers and ex-smokers with CD. In conclusion, cigarette smoking induces a pro-inflammatory epigenetic signature in ASCs that likely compromises their therapeutic potential.

- Abstract
Background and Aims: Crohn's disease [CD] is associated with complex microbe-host interactions, involving changes in microbial communities, and gut barrier defects, leading to the translocation of microorganisms to surrounding adipose tissue [AT]. We evaluated the presence of beige AT depots in CD and questioned whether succinate and/or bacterial translocation promotes white-to-beige transition in adipocytes., Methods: Visceral [VAT] and subcutaneous [SAT] AT biopsies, serum and plasma were obtained from patients with active [n = 21] or inactive [n = 12] CD, and from healthy controls [n = 15]. Adipose-derived stem cells [ASCs] and AT macrophages [ATMs] were isolated from VAT biopsies., Results: Plasma succinate levels were significantly higher in patients with active CD than in controls and were intermediate in those with inactive disease. Plasma succinate correlated with the inflammatory marker high-sensitivity C-reactive protein. Expression of the succinate receptor SUCNR1 was higher in VAT, ASCs and ATMs from the active CD group than from the inactive or control groups. Succinate treatment of ASCs elevated the expression of several beige AT markers from controls and from patients with inactive disease, including uncoupling protein-1 [UCP1]. Notably, beige AT markers were prominent in ASCs from patients with active CD. Secretome profiling revealed that ASCs from patients with active disease secrete beige AT-related proteins, and co-culture assays showed that bacteria also trigger the white-to-beige switch of ASCs from patients with CD. Finally, AT depots from patients with CD exhibited a conversion from white to beige AT together with high UCP1 expression, which was corroborated by in situ thermal imaging analysis., Conclusions: Succinate and bacteria trigger white-to-beige AT transition in CD. Understanding the role of beige AT in CD might aid in the development of therapeutic or diagnostic interventions., (© The Author(s) 2022.

- Abstract
Background: Patients with acute myocardial infarction (MI) are at high risk of upcoming events, in particular heart failure (HF), but reliable stratification methods are lacking. Our goal was to evaluate the potential role of circulating miRNAs as prognostic biomarkers in patients presenting with MI., Methods and Results: We conducted a prospective study among 311 consecutive patients hospitalized with MI (65% ST-segment elevation MI & median age of 55 years) with long-term follow-up. An initial screening was conducted to select candidate miRNAs, with subsequent study of 14 candidate miRNAs. The primary outcome was the composite of hospital admission for HF or cardiovascular death. During a mean follow-up of 2.1 years miR-21-5p, miR-23a-3p, miR27b-3p, miR-122-5p, miR210-3p, and miR-221-3p reliably predicted the primary outcome. Multivariate Cox regression analyses highlighted that miR-210-3p [hazard ratio (HR) 2.65 per 1 SD increase, P < 0.001], miR-23a-3p (HR 2.11 per 1 SD increase, P < 0.001), and miR-221-3p (HR 2.03 per 1 SD increase, P < 0.001) were able to accurately predict the primary outcome, as well as cardiovascular death, HF hospitalizations, and long-term New York Heart Association (NYHA) functional class. These three miRNAs clearly improved the performance of multivariate clinical models: ΔC-statistic = 0.10 [95% confidence interval (CI), 0.03-0.17], continuous net reclassification index = 34.8% (95%CI, 5.8-57.4%), and integrated discrimination improvement (P < 0.001)., Conclusions: This is the largest study evaluating the prognostic value of circulating miRNAs for HF-related events among patients with MI. We show that several miRNAs predict HF hospitalizations, cardiovascular mortality, and poor long-term NYHA status and improve current risk prediction methods., (© 2022 The Authors.

- Abstract
Anti-TNF biologics have been shown to markedly improve the quality of life for patients with Crohn's disease (CD), yet one-third of patients fail to benefit from this treatment. Patients with CD develop a characteristic wrapping of visceral adipose tissue (VAT) in the inflamed intestinal area, termed creeping fat, and it is known that adipose tissue expansion influences the efficacy of anti-TNF drugs. We questioned whether anti-TNF therapies impact the creeping fat in CD, which might affect the outcome of the disease. Adipose tissue biopsies were obtained from a cohort of 14 patients with CD that received anti-TNF drugs and from 29 non-anti-TNF-treated patients (control group) matched by sex, age, and body mass index undergoing surgical interventions for symptomatic complications. We found that anti-TNF therapies restored adipose tissue morphology and suppressed immune cell infiltration in the creeping fat. Additionally, anti-TNF treatments appeared to markedly improve the pro-inflammatory phenotype of adipose-tissue macrophages and adipose-tissue-derived stem cells. Our study provides evidence that anti-TNF medications influence immune cells and progenitor cells in the creeping of patients with CD, suppressing inflammation. We propose that perilesional VAT should be considered when administering anti-TNF therapy in patients with CD.

- Abstract
(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31-56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery.

- Abstract
Our understanding of the interplay between human adipose tissue and the immune system is limited. The mesothelium, an immunologically active structure, emerged as a source of visceral adipose tissue. After investigating the mesothelial properties of human visceral and subcutaneous adipose tissue and their progenitors, we explored whether the dysfunctional obese and Crohn's disease environments influence the mesothelial/mesenchymal properties of their adipocyte precursors, as well as their ability to mount an immune response. Using a tandem transcriptomic/proteomic approach, we evaluated the mesothelial and mesenchymal expression profiles in adipose tissue, both in subjects covering a wide range of body-mass indexes and in Crohn's disease patients. We also isolated adipose tissue precursors (adipose-derived stem cells, ASCs) to assess their mesothelial/mesenchymal properties, as well as their antigen-presenting features. Human visceral tissue presented a mesothelial phenotype not detected in the subcutaneous fat. Only ASCs from mesenteric adipose tissue, named creeping fat, had a significantly higher expression of the hallmark mesothelial genes mesothelin ( MSLN ) and Wilms' tumor suppressor gene 1 ( WT1 ), supporting a mesothelial nature of these cells. Both lean and Crohn's disease visceral ASCs expressed equivalent surface percentages of the antigen-presenting molecules human leucocyte antigen-DR isotype (HLA-DR) and CD86. However, lean-derived ASCs were predominantly HLA-DR
dim , whereas in Crohn's disease, the HLA-DRbright subpopulation was increased 3.2-fold. Importantly, the mesothelial-enriched Crohn's disease precursors activated CD4+ T-lymphocytes. Our study evidences a mesothelial signature in the creeping fat of Crohn's disease patients and its progenitor cells, the latter being able to present antigens and orchestrate an immune response.- Published

- Abstract
Background: Cystic fibrosis (CF) patients have an alteration in fatty acid (FA) metabolism, associated with increased omega-6 and low omega-3 FA. Previous studies on supplementation with omega-3 FA in CF had contradictory results, and to date there is no evidence to recommend routine use of omega-3 supplements in CF patients. We hypothesized that long-term supplementation with docosahexaenoic acid (DHA) will have beneficial effects in these patients, by reducing pulmonary, systemic and intestinal inflammation., Methods: This was a randomized, double-blind, parallel, placebo-controlled trial. CF patients (age >2 months) were randomized to receive a seaweed DHA oil solution (50 mg/Kg/day) or matching placebo for 48 weeks. Primary outcomes were pulmonary (interleukin [IL]-8), systemic (IL-8) and intestinal (calprotectin) inflammatory biomarkers. Secondary outcomes included other pulmonary (IL-1β, IL-6, neutrophil elastase, lactate and calprotectin) and systemic (serum-IL-1β, IL-6) inflammatory biomarkers, as well as clinical outcomes (FEV
1 , pulmonary exacerbations, antibiotic use, nutritional status and quality of life)., Results: Ninety six CF patients, 44 female, age 14.6±11.9 years (48 DHA and 48 placebo) were included. At trial completion, there were no differences in all primary outcomes [serum-IL-8 (p=0.909), respiratory-IL-8 (p=0.384) or fecal calprotectin (p=0.948)], all secondary inflammatory biomarkers, or in any of the clinical outcomes evaluated. There were few adverse events, with similar incidence in both study groups., Conclusion: In this study, long-term DHA supplementation in CF patients was safe, but did not offer any benefit on inflammatory biomarkers, or in clinical outcomes compared with placebo.

- Abstract
Crohn's disease (CD) is characterized by compromised immune tolerance to the intestinal commensal microbiota, intestinal barrier inflammation, and hyperplasia of creeping fat (CF) and mesenteric adipose tissue (AT), which seems to be directly related to disease activity. Gut microbiota dysbiosis might be a determining factor in CD etiology, manifesting as a low microbial diversity and a high abundance of potentially pathogenic bacteria. We tested the hypothesis that CF is a reservoir of bacteria through 16S-rRNA sequencing of several AT depots of patients with active and inactive disease and controls. We found a microbiome signature within CF and mesenteric AT from patients, but not in subcutaneous fat. We failed to detect bacterial DNA in any fat depot of controls. Proteobacteria was the most abundant phylum in both CF and mesenteric AT, and positively correlated with fecal calprotectin/C-reactive protein. Notably, the clinical status of patients seemed to be related to the microbiome signature, as those with the inactive disease showed a reduction in the abundance of pathogenic bacteria. Predictive functional profiling revealed many metabolic pathways including lipopolysaccharide biosynthesis and sulfur metabolism overrepresented in active CD relative to that in inactive CD. Our findings demonstrate that microbiota dysbiosis associated with CD pathophysiology is reflected in AT and might contribute to disease severity.

- Abstract
Background: Crohn's disease (CD) is characterized by persistent inflammation and ulceration of the small or large bowel, and expansion of mesenteric adipose tissue, termed creeping fat (CF). We previously demonstrated that human adipose-derived stem cells (hASCs) from CF of patients with CD exhibit dysfunctional phenotypes, including a pro-inflammatory profile, high phagocytic capacity, and weak immunosuppressive properties. Importantly, these phenotypes persist in patients in remission and are found in all adipose depots explored including subcutaneous fat. We hypothesized that changes in hASCs are a consequence of epigenetic modifications., Methods: We applied epigenome-wide profiling with a methylation array (Illumina EPIC/850k array) and gene expression analysis to explore the impact of CD on the methylation signature of hASCs isolated from the subcutaneous fat of patients with CD and healthy controls (n = 7 and 5, respectively; cohort I). Differentially methylated positions (p value cutoff < 1 × 10
-4 and ten or more DMPs per gene) and regions (inclusion threshold 0.2, p value cutoff < 1 × 10-2 and more than 2 DMRs per gene) were identified using dmpfinder and Bumphunter (minfi), respectively. Changes in the expression of differentially methylated genes in hASCs were validated in a second cohort (n = 10/10 inactive and active CD and 10 controls; including patients from cohort I) and also in peripheral blood mononuclear cells (PBMCs) of patients with active/inactive CD and of healthy controls (cohort III; n = 30 independent subjects)., Results: We found a distinct DNA methylation landscape in hASCs from patients with CD, leading to changes in the expression of differentially methylated genes involved in immune response, metabolic, cell differentiation, and development processes. Notably, the expression of several of these genes in hASCs and PBMCs such as tumor necrosis factor alpha (TNFA) and PR domain zinc finger protein 16 (PRDM16) were not restored to normal (healthy) levels after disease remission., Conclusions: hASCs of patients with CD exhibit a unique DNA methylation and gene expression profile, but the expression of several genes are only partially restored in patients with inactive CD, both in hASCs and PBMCs. Understanding how CD shapes the functionality of hASCs is critical for investigating the complex pathophysiology of this disease, as well as for the success of cell-based therapies. Human adipose-stem cells isolated from subcutaneous fat of patients with Crohn's disease exhibit an altered DNA methylation pattern and gene expression profile compared with those isolated from healthy individuals, with immune system, cell differentiation, metabolic and development processes identified as the main pathways affected. Interestingly, the gene expression of several genes involved in these pathways is only partially restored to control levels in patients with inactive Crohn's disease, both in human adipose-stem cells and peripheral blood mononuclear cells. Understanding how Crohn's disease shapes the functionality of human adipose-stem cells is critical for investigating the complex pathophysiology of this disease, as well as for the success of cell-based therapies.- Published

- Abstract
Crohn's disease (CD) is characterized by the expansion of mesenteric fat, also known as "creeping fat." We explored the plasticity and immune properties of adipose-derived stem cells (ASCs) in the context of CD as potential key players in the development of creeping fat. Mesenteric CD-derived ASCs presented a more proliferative, inflammatory, invasive, and phagocytic phenotype than equivalent cells from healthy donors, irrespective of the clinical stage. Remarkably, ASCs from the subcutaneous depot of patients with CD also showed an activated immune response that was associated with a reduction in their immunosuppressive properties. The invasive phenotype of mesenteric CD ASCs was governed by an inflammasome-mediated inflammatory state since blocking inflammasome signaling, mainly the secretion of interleukin-1β, reversed this characteristic. Thus, CD alters the biological functions of ASCs as adipocyte precursors, but also their immune properties. Selection of ASCs with the best immunomodulatory properties is advocated for the success of cell-based therapies., (Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.)

- Abstract
Objectives: The aims of this study were to assess the risk of relapse after discontinuation of anti-tumor necrosis factor (anti-TNF) drugs in patients with inflammatory bowel disease (IBD), to identify the factors associated with relapse, and to evaluate the overcome after retreatment with the same anti-TNF in those who relapsed., Methods: This was a retrospective, observational, multicenter study. IBD patients who had been treated with anti-TNFs and in whom these drugs were discontinued after clinical remission was achieved were included., Results: A total of 1,055 patients were included. The incidence rate of relapse was 19% and 17% per patient-year in Crohn's disease and ulcerative colitis patients, respectively. In both Crohn's disease and ulcerative colitis patients in deep remission, the incidence rate of relapse was 19% per patient-year. The treatment with adalimumab vs. infliximab (hazard ratio (HR)=1.29; 95% confidence interval (CI)=1.01-1.66), elective discontinuation of anti-TNFs (HR=1.90; 95% CI=1.07-3.37) or discontinuation because of adverse events (HR=2.33; 95% CI=1.27-2.02) vs. a top-down strategy, colonic localization (HR=1.51; 95% CI=1.13-2.02) vs. ileal, and stricturing behavior (HR=1.5; 95% CI=1.09-2.05) vs. inflammatory were associated with a higher risk of relapse in Crohn's disease patients, whereas treatment with immunomodulators after discontinuation (HR=0.67; 95% CI=0.51-0.87) and age (HR=0.98; 95% CI=0.97-0.99) were protective factors. None of the factors were predictive in ulcerative colitis patients. Retreatment of relapse with the same anti-TNF was effective (80% responded) and safe., Conclusions: The incidence rate of inflammatory bowel disease relapse after anti-TNF discontinuation is relevant. Some predictive factors of relapse after anti-TNF withdrawal have been identified. Retreatment with the same anti-TNF drug was effective and safe.

- Abstract
Objective: The purpose of this study was to compare the multifidus electromyographic activity in healthy women during the performance of the same Pilates exercise under 2 conditions., Methods: Sixteen healthy, active, female practitioners of Pilates (mean age, 24.3; SD, 3.1 years) were assessed through surface electromyography during 2 Pilates exercises (swan dive and breast stroke). Muscle activity during the experimental tasks was recorded with 1 pair of electrodes placed bilaterally on the multifidi. Data were normalized to maximal activity recorded during dynamic activity., Results: The mean of the maximal isometric voluntary contraction was 662.4 N (SD, 195). In the phase comparison, the multifidus was the most recruited on the concentric phase during both exercises, ball (P=.001) and reformer (P=.001). In the comparison between conditions, the reformer presented more activation on swan dive (P=.04) and breast stroke (P=.001). The percentages of muscle activation varied between 50% and 60%, and the greatest activation was made on the reformer condition., Conclusion: The findings of this study show that Pilates exercises by healthy women, under different conditions, can cause changes to the multifidus muscle activation. The condition and the phase in which the muscle was more activated were the reformer and concentric phase, respectively, for both exercises. However, the results for the percentages of activation suggest that the intensity of recruitment may not be sufficient to strengthen muscle in healthy, trained subjects., (Copyright © 2013 National University of Health Sciences.

- Abstract
The purpose of this study was to evaluate the trunk muscles activity of hemiparetic and control subjects during selected therapeutic exercises with surface electromyography (sEMG). The sEMG evaluation included 12 subjects presenting hemiparesis after having suffered a unilateral stroke and 12 apparently healthy subjects. A 16-channel sEMG system was used; data were band pass filtered from 20 to 450Hz. The signal was normalized through reference voluntary contraction (RVC) and presented in percentage. The exercises used in the evaluations were trunk flexion and trunk extension. Rectus abdominis presented greater activation on the paretic side of the experimental group than on the corresponding side of the control group (P=0.035) (Cohen's d¯=0.94). During leg elevation, the non-paretic obliquus externus abdominis showed greater activation than in other exercises (P=0.019) (Cohen's d¯=0.75). No inter-group differences were found for either erectus spinae activity or contraction onset. Experimental group subjects showed muscle activity alterations, principally in the rectus abdominis, indicating the occurrence of compensatory strategies., (Copyright © 2010 Elsevier Ltd.

- Abstract
Unilateral renal ischemia for 40 min in rat results in increased fibronectin (FN) expression in proximal tubular cells. This study examines the role of 24 h of blood reperfusion and the role of the renin-angiotensin system (RAS) on these results. Rats were submitted to 40 min of unilateral renal ischemia followed by 24 h of blood reperfusion. Renal function was assayed by clearance measurement in metabolic cages. Intracellular ATP and calcium were determined in proximal tubules. The expression and abundance of FN were investigated by reverse transcription-polymerase chain reaction, ELISA and Western blot either in isolated proximal tubules or cortex homogenates from control, ischemic and ischemic with reperfusion rats. Matrix metalloproteases (MMPs) activity was also measured. Losartan effects on renal function and on the abundance of FN and the MMPs activity in cortical homogenates were also measured. The renal function remained altered after 24 h of reperfusion in untreated and losartan-treated ischemic rats. On the other hand, the abundance of FN is increased after reperfusion both in isolated proximal tubules and total cortex homogenates and the same pattern was observed in the MMPs activity. Twenty-four h of blood reperfusion presented FN-mRNA signals similar to control ones. Losartan pretreated-rats presented diminished FN abundance in homogenates of cortex tissue from ischemic rats with or without reperfusion. Similar results were observed in the MMPs-activity. These results suggest that angiotensin II acting via the AT1 receptor plays a role in the development of tubulointersticial fibrosis after ischemia-reperfusion by activation of intrarenal RAS from the injured kidney.

- Abstract
Background/aims: Selective intestinal decontamination with norfloxacin is widely used to prevent spontaneous bacterial infections in cirrhosis. The study was performed to compare the spontaneous bacterial peritonitis occurring in patients with and without prophylactic norfloxacin., Methods: Two hundred and twenty-nine consecutive episodes of spontaneous bacterial peritonitis, (193 in patients without (Group A) and 36 in patients with norfloxacin prophylaxis (Group B)), were retrospectively analyzed. In 100 episodes (86 and 14, respectively), the responsible organism was isolated in ascitic fluid., Results: Clinical and laboratory data at diagnosis were comparable in both groups. There were marked differences (p < 0.001) between group A and B in the frequency of peritonitis caused by gram-negative (67.4% vs. 14.3%) and gram-positive (30.2% vs. 78.6%) bacteria. There were three polymicrobial episodes. Bacteria resistant to cefotaxime and gram-negative bacilli resistant to quinolones were isolated in ascitic fluid in nine (seven in Group A and two in Group B) and three episodes (all in Group A), respectively. No differences in the course of infection and patient survival were observed between groups., Conclusions: Spontaneous bacterial peritonitis in patients with and without prophylaxis with norfloxacin are not different in clinical features, response to treatment and prognosis. Spontaneous bacterial peritonitis caused by gram-negative organisms resistant to quinolones is extremely uncommon in patients with cirrhosis receiving prophylactic norfloxacin.
