Effect of seedling size on post-planting growth and survival of five Mexican species and their hybrids.

Background: Seedling growth and survival depend on seedling quality. However, there is no experimental evidence showing that the seedling dimensions of the abundant, economically important and widely distributed tree species , , , , and and their hybrids effectively improve survival and growth in reforestations and plantations in Mexico. Therefore, the aim was to evaluate the influence of initial morphological parameters of 2,007 nursery seedlings of these species and their hybrids on their growth and survival 44 months after planting in the Sierra Madre Occidental, Mexico.

Psychological disorders and coping strategies in patients with inflammatory bowel disease. Their impact on health-related quality of life.

Background And Objectives: inflammatory bowel disease (IBD) has a major impact on psychological well-being. This condition is associated with a high level of anxiety and mood disorders, but stress prevalence and how an individual copes with IBD have not been sufficiently explored. The objective of this study was to assess the impact of the disease on psychological disorders and to identify coping strategies used by patients with IBD, as well as to analyze the relationship between these variables and sociodemographic and clinical variables.

Effectiveness and Safety of Ustekinumab in Elderly Patients with Crohn's Disease: Real World Evidence From the ENEIDA Registry.

Background And Aims: Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD.

Association of golimumab trough concentrations during maintenance with clinical, biological, endoscopic and histologic remission in patients with ulcerative colitis.

Background: Optimal golimumab concentration thresholds for important outcomes during maintenance are lacking.

Aims: To investigate the association of golimumab trough concentrations during maintenance with key outcomes, including endoscopic and histologic remission, and long-term event-free persistence with golimumab, in patients with UC.

Methods: This multi-centre, cross-sectional study included patients with UC on golimumab maintenance recruited either in remission or during a flare.

Incidence, Clinical Characteristics and Management of Inflammatory Bowel Disease in Spain: Large-Scale Epidemiological Study.

(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.

Effectiveness and Safety of Ustekinumab in Ulcerative Colitis: Real-world Evidence from the ENEIDA Registry.

Background And Aims: The development programm UNIFI has shown promising results of ustekinumab in ulcerative colitis [UC] treatment which should be confirmed in clinical practice. We aimed to evaluate the durability, effectiveness, and safety of ustekinumab in UC in real life.

Methods: Patients included in the prospectively maintained ENEIDA registry, who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score [PMS]>2], were included.

Re-induction With Intravenous Ustekinumab in Patients With Crohn's Disease and a Loss of Response to This Therapy.

Background: A significant percentage of patients treated with ustekinumab may lose response. Our aim was to evaluate the short-term efficacy and safety of intravenous re-induction with ustekinumab in patients with Crohn's disease who have lost the response to the treatment.

Methods: This is a retrospective, observational, multicenter study.

The COVID-19 pandemic shows us in which way the care of patients with inflammatory bowel disease should move.

The COVID-19 pandemic has forced major changes in the care of patients with inflammatory bowel disease (IBD). The articles by El Hajra et al. and Fernández Álvarez el al.

Comparison of original and biosimilar infliximab (CTP-13) in biologic-naïve patients with Crohn's disease and ulcerative colitis: a retrospective, multicenter real-life study in Spain.

Purpose: biosimilar infliximab (CTP-13) has been recently approved for the treatment of several immune-mediated inflammatory disorders, including inflammatory bowel disease (IBD). Comparative studies between this biosimilar and original infliximab in the real clinical practice are scarce. The objective of this study was to compare short and long-term safety and efficacy of original (O) and biosimilar infliximab (B-IFX) in biologic-naïve, IBD patients in the real life clinical practice.

Antitumor Necrosis Factor Agents to Treat Endoscopic Postoperative Recurrence of Crohn's Disease: A Nationwide Study With Propensity-Matched Score Analysis.

Introduction: Patients with Crohn's disease experiencing endoscopic postoperative recurrence (POR) may benefit from antitumor necrosis factor (TNF) agents but scarce data on this are available. Our aim was to assess the efficacy of anti-TNF in improving mucosal lesions in patients with endoscopic POR.

Methods: Multicenter, retrospective, study of patients with Crohn's disease who underwent therapy with anti-TNF agents for endoscopic POR (Rutgeerts score > i1).

Autoimmune hepatitis, primary sclerosing cholangitis, and inflammatory bowel disease. Sequential overlap syndrome: a twist to the mosaic of autoimmunity.

Autoimmune liver diseases can overlap resulting in a new entity, phenotypically different from those pathologies that converge, and that demonstrates the complexity of our immune system. Sequential overlap syndrome is the consecutive presentation, separated by a variable period of time, of two liver autoimmune diseases, mostly autoimmune hepatitis and primary biliary cholangitis. This syndrome constitutes a challenge both in its diagnosis and in its treatment given the exceptional nature of its presentation.

Predicting forest fire kernel density at multiple scales with geographically weighted regression in Mexico.

Identifying the relative importance of human and environmental drivers on fire occurrence in different regions and scales is critical for a sound fire management. Nevertheless, studies analyzing fire occurrence spatial patterns at multiple scales, covering the regional to national levels at multiple spatial resolutions, both in the fire occurrence drivers and in fire density, are very scarce. Furthermore, there is a scarcity of studies that analyze the spatial stationarity in the relationships of fire occurrence and its drivers at multiple scales.
