Chronic intestinal pseudo-obstruction (CIPO) is a rare condition affecting the motility of the lower gastrointestinal tract, while achalasia is an uncommon esophageal motility disorder. The coexistence of both conditions is extremely rare. We present the case of a patient who had both pathologies, admitted for dysphagia and oral intolerance, the symptoms finally resolved by performing a POEM.

Background: Recently, we have identified a dysregulated protein signature in the esophageal epithelium of eosinophilic esophagitis (EoE) patients including proteins associated with inflammation and epithelial barrier function; however, the effect of proton pump inhibitor (PPI) treatment on this signature is unknown. Herein, we used a proteomic approach to investigate: (1) whether PPI treatment alters the esophageal epithelium protein profile observed in EoE patients and (2) whether the protein signature at baseline predicts PPI response.

Methods: We evaluated the protein signature of esophageal biopsies using a cohort of adult EoE (n = 25) patients and healthy controls (C) (n = 10).

Objectives: The aim of the study was to characterize the circulating immunome of patients with EoE before and after proton pump inhibitor (PPI) treatment in order to identify potential non-invasive biomarkers of treatment response.

Methods: PBMCs from 19 healthy controls and 24 EoE patients were studied using a 39-plex spectral cytometry panel. The plasmacytoid dendritic cell (pDC) population was differentially characterized by spectral cytometry analysis and immunofluorescence assays in esophageal biopsies from 7 healthy controls and 13 EoE patients.

Article Synopsis
  • Swallowed topical corticosteroids (tC) are commonly used to treat eosinophilic esophagitis (EoE), but their effectiveness varies due to different formulations and doses.
  • A study analyzed data from the EoE CONNECT registry, focusing on clinical and histological remission rates based on various tC treatments used in real-world settings.
  • Results showed that higher doses (≥0.8 mg/day) improved remission rates, budesonide orodispersible tablets were the most effective, and factors like reduced symptom severity influenced treatment outcomes.

Background: active eosinophilic esophagitis is associated with esophageal caliber, distensibility and motility changes that may be reversed with treatment.

Objectives: to study esophageal diameter, distensibility and contractility in healthy subjects compared to patients with eosinophilic esophagitis, both before and after treatment.

Methods: a quasi-experimental study, EndoFLIP™, was used to analyze the esophageal body and esophago-gastric junction (EGJ) in all three groups, and a program was designed to obtain esophageal diameter, distensibility and contractility values.

Objective: To compare neonatal outcomes between water births, births with immersion only during labour, and births in which immersion was never used.

Methods: A retrospective cohort study was performed including mother-baby dyads attended between 2009 and 2019 at the Hospital do Salnés regional hospital (Pontevedra, Spain). These women were categorised into 3 groups: water birth; immersion only during dilation; and women who never used immersion.

Article Synopsis
  • Eosinophilic esophagitis (EoE) is a chronic allergic disease affecting the esophagus, and researchers used proteomics and RNA sequencing to study changes in the esophageal tissue of EoE patients compared to healthy controls.
  • Out of 1667 identified proteins, 363 were differentially accumulated in EoE, while RNA sequencing revealed 1993 differentially expressed genes, highlighting a significant correlation between RNA and protein levels, especially for certain mRNA-protein pairs.
  • The study provided new insights into the pathogenesis of EoE, revealing alterations in immune responses and epithelial processes, and emphasized the importance of combining proteomic and transcriptomic data for a better

Morphine and other opioid analgesics are the drugs of election to treat moderate-to-severe pain, and they elicit their actions by binding to the opioid receptors. Cocaine is a potent inhibitor of dopamine, serotonin, and noradrenaline reuptake, as it blocks DAT, the dopamine transporter, causing an increase in the local concentration of these neurotransmitters in the synaptic cleft. The molecular effects of these drugs have been studied in specific brain areas or nuclei, but the systemic effects in the whole organism have not been comprehensively analyzed.

Background: Poor adherence to clinical practice guidelines for eosinophilic esophagitis (EoE) has been described and the diagnostic delay of the disease continues to be unacceptable in many settings.

Objective: To analyze the impact of improved knowledge provided by the successive international clinical practice guidelines on reducing diagnostic delay and improving the diagnostic process for European patients with EoE.

Methods: Cross-sectional analysis of the EoE CONNECT registry based on clinical practice.

Purpose: To evaluate the response of the four smallest active volume thimble type ionization chambers commercially available (IBA-dosimetry RAZOR Nano Chamber, Standard Imaging Exradin A16, IBA-dosimetry CC01 and PTW T31022) when measuring SRS cone collimated Flattening Filter Free (FFF) fields.

Methods: We employed Monte Carlo simulation for calculating correction factors as defined in IAEA TRS-483. Monte Carlo simulation beam model and ion chamber geometry definitions were supported by an extensive set of measurements.

Phosphorus absorbed in the form of phosphate (H PO ) is an essential but limiting macronutrient for plant growth and agricultural productivity. A comprehensive understanding of how plants respond to phosphate starvation is essential for the development of more phosphate-efficient crops. Here we employed label-free proteomics and phosphoproteomics to quantify protein-level responses to 48 h of phosphate versus phosphite (H PO ) resupply to phosphate-deprived Arabidopsis thaliana suspension cells.

In this work we have created and commissioned a Monte Carlo model of 6FFF Varian TrueBeam linear accelerator using BEAMnrc. For this purpose we have experimentally measured the focal spot size and shape of three Varian TrueBeam treatment units in 6FFF modality with a slit collimator and several depth dose and lateral beam profiles in a water phantom. The Monte Carlo model of a 6FFF TrueBeam machine was implemented with a primary electron source commissioned as a 2D Gaussian with Full Width Half Maximum selected by comparison of simulated and measured narrow beam profiles.

Patients with chronic kidney disease (CKD) are at an increased risk of premature mortality, mainly from cardiovascular causes. The association between CKD on hemodialysis and accelerated atherosclerosis was described >40 years ago. However, more recently, it has been suggested that the increase in atherosclerosis risk is actually observed in early CKD stages, remaining stable thereafter.

fixes atmospheric nitrogen (N) and distributes it back into ecosystems. We hypothesize that biological nitrogen fixation in this plant species is limited by competition from the invasive shrub, . Competition would therefore result in the legume plant switching its limited nitrogen (N) sources in phosphorus-poor soils in savannah ecosystems when resources have to be shared.

is a tree legume that grows in the Cape Floristic Region (CFA) in poor nutrient soils. A comparison between high and low phosphate growth conditions between roots and nodules was conducted and evaluated for the plants ability to cope under low phosphate stress conditions in . We proved that the plant copes with low phosphate stress through an increased allocation of resources, reliance on BNF and enhanced enzyme activity, especially PEPC.

Background: Kidney transplantation (KT) candidates often present with multiple comorbidities. These patients also have a substantial burden of frailty, which is also associated with increased mortality. However, it is unknown if frailty is merely a surrogate for comorbidity, itself an independent domain of risk, or if frailty and comorbidity have differential effects.

Introduction: Patients with chronic kidney disease (CKD) and diabetes mellitus (DM) have high cardiovascular risk. Both conditions are related to systemic atherosclerosis and vascular calcification. The prevalence and severity of coronary artery calcification (CaC) is higher in patients with DM, regardless of their renal function.
