Deep learning on CT scans to predict checkpoint inhibitor treatment outcomes in advanced melanoma.

Immune checkpoint inhibitor (ICI) treatment has proven successful for advanced melanoma, but is associated with potentially severe toxicity and high costs. Accurate biomarkers for response are lacking. The present work is the first to investigate the value of deep learning on CT imaging of metastatic lesions for predicting ICI treatment outcomes in advanced melanoma.

Versatile waste wood-chitosan composites for 2,4-D and paraquat adsorption: Isotherm modelling and thermodynamic evaluation.

2,4-dichlorophenoxy acetic acid (2,4-D) and 1,1-dimethyl-4,4-bipiridinium chloride (paraquat) are among the most widely used herbicides and are known to be toxic. Fabrication of green adsorbents which are capable of removing both herbicides remains a challenge. Here, we fabricate a novel adsorbent from tropical waste wood and use a facile, chitosan-mediated N-heteroatom functionalization technique to augment surface nitrogen and improve specific surface area.

The effect of adsorbent textural and functional properties on model naphthenic acid adsorption.

Naphthenic acids, NAs, are a major contaminant of concern and a focus of much research around remediation of oil sand process affected waters, OSPW. Using activated carbon adsorbents are an attractive option given their low cost of fabrication and implementation. A deeper evaluation of the effect NA structural differences have on uptake affinity is warranted.

Explorative study on the value of hepcidin in predicting iron non-responsiveness in paediatric inflammatory bowel disease.

Background: In a considerable proportion of anaemic children with inflammatory bowel disease (IBD), haemoglobin (Hb) does not normalise after iron therapy. We evaluated the added value of novel iron markers (hepcidin and soluble transferrin receptor [sTfR]) as compared to traditional iron markers (ferritin and transferrin saturation [TSAT]) to determine the best strategy for the prediction of non-responsiveness to iron suppletion.

Methods: In this secondary analysis of prospectively collected data, we measured iron markers in anaemic children (Hb Z-score < -2.

Development of a Clinical Pathway for Bariatric Surgery as an Integral Part of a Comprehensive Treatment for Adolescents with Severe Obesity in the Netherlands.

Introduction: In the Netherlands, bariatric surgery in adolescents is currently only allowed in the context of scientific research. Besides this, there was no clinical pathway for bariatric surgery in adolescents. In this paper, the development of a comprehensive clinical pathway for bariatric surgery in adolescents with severe obesity in the Netherlands is described.

Gluten-free diet for pediatric patients with coeliac disease: A position paper from the ESPGHAN gastroenterology committee, special interest group in coeliac disease.

Background And Objective: Coeliac disease is a chronic, immune-mediated disorder for which the only treatment consists of lifelong strict adherence to gluten-free diet (GFD). However, there is a lack of evidence-based guidelines on the GFD dietary management of coeliac disease. This position paper, led by the Special Interest Group in coeliac disease of the European Society of Pediatric, Gastroenterology Hepatology, and Nutrition, supported by the Nutrition Committee and the Allied Health Professionals Committee, aims to present evidence-based recommendations on the GFD as well as how to support dietary adherence.

Noninvasive scores are poorly predictive of histological fibrosis in paediatric fatty liver disease.

Objectives: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children. Roughly a quarter of paediatric patients with NAFLD develop nonalcoholic steatohepatitis and fibrosis. Here, we evaluated the diagnostic accuracy of previously published noninvasive fibrosis scores to predict liver fibrosis in a large European cohort of paediatric patients with NAFLD.

TbsP and TrmB jointly regulate gapII to influence cell development phenotypes in the archaeon Haloferax volcanii.

Microbial cells must continually adapt their physiology in the face of changing environmental conditions. Archaea living in extreme conditions, such as saturated salinity, represent important examples of such resilience. The model salt-loving organism Haloferax volcanii exhibits remarkable plasticity in its morphology, biofilm formation, and motility in response to variations in nutrients and cell density.

Early infliximab trough levels in paediatric IBD patients predict sustained remission.

Background: Exposure-response studies have shown that higher infliximab concentrations are associated with better outcomes in inflammatory bowel disease. There is little agreement about the optimal time to measure infliximab levels in children.

Objectives: We aimed to evaluate whether trough levels at week 6 or week 14 predict sustained remission.

Weight Loss and Glycemic Control After Bariatric Surgery in Adolescents With Severe Obesity: A Randomized Controlled Trial.

Purpose: Bariatric surgery is regarded as a valuable treatment option for adolescents with severe obesity. However, high-quality evidence of its superiority over prolonged conservative treatment with multidisciplinary lifestyle intervention (MLI) is limited. This study investigated the efficacy and safety of bariatric surgery in adolescents without sufficient weight loss after MLI for severe obesity.

Comparing the use of food and physical activity parenting practices: Parents of children with overweight and obesity versus parents of children with a healthy weight.

Background: Paediatric overweight and obesity are caused by a complex imbalance between energy intake and expenditure. Parents may influence this imbalance through energy balance-related parenting practices. This study aims to compare the use of energy balance-related parenting practices between parents of children with overweight and obesity and children with a healthy weight.

Selenite Adsorption and Reduction via Iron(II) Impregnated Activated Carbon Produced from the Phosphoric Acid Activation of Construction Waste Wood.

Chemical activation of waste materials, to form activated carbon, (AC) is complicated by the large amounts of chemical activating agents required and wastewater produced. To address these problems, we have developed an optimized process for producing AC, by phosphoric acid activation of construction waste. Waste wood from construction sites was ground and treated with an optimized phosphoric acid digestion and activation that resulted in high surface areas (> 2000 m/g) and a greater recovery of phosphoric acid.

Metal-Impregnated Petroleum Coke-Derived Activated Carbon for the Adsorption of Arsenic in Acidic Waters.

The efficacy of metal-impregnated petroleum coke (PC) activated carbon for the adsorption of arsenite and arsenate in acidic waters is investigated in this study. Unmodified PC activated carbon, FeCl-loaded activated carbon, KMnO-loaded activated carbon, and a mixed FeCl-KMnO-loaded activated carbon were used for evaluation. The surface characteristics of the activated carbons before and after arsenic adsorption were analyzed by X-ray photoelectron spectroscopy (XPS).

Design: A qualitative study design using semi-structured individual interviews and focus-group discussions (FGD) was used. Basic socio-demographic information was obtained from all participants.

Fatigue and Physical Activity Patterns in Children With Inflammatory Bowel Disease.

Objectives: Fatigue is a common symptom in children with inflammatory bowel disease (IBD). Diagnostic tests to evaluate biological causes of fatigue commonly include markers of inflammation and hemoglobin (Hb), yet functional parameters have been inadequately studied in pediatric IBD. In this study, we compared fatigued and non-fatigued children with IBD from both a biological and functional point of view.

A Population-Based Cohort Study on Efficacy and Safety of Bariatric Surgery in Young Adults Versus Adults.

Purpose: Bariatric surgery is the most effective treatment for severe obesity in adults and has shown promising results in young adults. Lack of insight regarding efficacy and safety outcomes might result in delayed bariatric surgery utilization in young adults. Therefore, this study aimed to assess the efficacy and safety of bariatric surgery in young adults compared to adults.

Nutrient deficiencies in children with celiac disease during long term follow-up.

Background: Celiac disease (CD) is associated with malabsorption and consequential nutritional deficiencies. Patients with CD must follow a gluten-free diet (GFD), which is also associated with nutrient deficiencies. Despite the clinical significance, consensus is lacking on the pattern and frequency of nutrient deficiencies in CD and the usefulness of assessment during follow-up.

CT radiomics compared to a clinical model for predicting checkpoint inhibitor treatment outcomes in patients with advanced melanoma.

Introduction: Predicting checkpoint inhibitors treatment outcomes in melanoma is a relevant task, due to the unpredictable and potentially fatal toxicity and high costs for society. However, accurate biomarkers for treatment outcomes are lacking. Radiomics are a technique to quantitatively capture tumour characteristics on readily available computed tomography (CT) imaging.

Celiac Disease and the Gluten Free Diet during the COVID-19 Pandemic: Experiences of Children and Parents.

The COVID-19 pandemic perturbed the everyday life of children and those with chronic illnesses, along with the lives of their families. Patients with celiac disease (CD) follow a strict gluten-free diet (GFD), and gluten ingestion is associated with negative health outcomes. The aim of this study was to investigate the experiences of children with CD and their families concerning their GFD, symptoms and CD management during the first period of the COVID-19 pandemic.

Transforming micropores to mesopores by heat cycling KOH activated petcoke for improved kinetics of adsorption of naphthenic acids.

Formation of activated carbon from petroleum coke by KOH, results in high specific surface area materials that are predominantly microporous. This initial microporosity means that the adsorption kinetics of target species are not as rapid as they could be, thus limiting environmental remediation applications for the material. To address this problem a series of additional heat cycles with no additional chemical inputs were applied after activation but prior to the removal of activating agents.

The Hypersaline Archaeal Histones HpyA and HstA Are DNA Binding Proteins That Defy Categorization According to Commonly Used Functional Criteria.

Histone proteins are found across diverse lineages of , many of which package DNA and form chromatin. However, previous research has led to the hypothesis that the histone-like proteins of high-salt-adapted archaea, or halophiles, function differently. The sole histone protein encoded by the model halophilic species Halobacterium salinarum, HpyA, is nonessential and expressed at levels too low to enable genome-wide DNA packaging.

Health-Related Quality of Life in Children and Adolescents with Overweight, Obesity, and Severe Obesity: A Cross-Sectional Study.
