The goal of the treatment is to relieve symptoms, achieve duodenal mucosal healing, avoid long term complications, and ensure children´s appropriate growth, for which it´s necessary to follow a lifelong, nutritionally complete and healthy gluten free diet (GFD). The Celiac Disease Working Group of the Gastroenterology Committee of the Sociedad Argentina de Pediatría developed this guide based on expert consensus, aimed at gastroenterologists, pediatricians and primary care physicians with the objective of updating the following topics: Treatment. Definition of gluten free food.

Celiac disease is a chronic condition that affects approximately 1% of the world's population, becoming a public health problem. The numerous publications and international guides published in recent years make it necessary to update aspects related to its diagnosis. Highly sensitive and specific serological determinations have allowed the identification of the clinical polymorphism.

The ever-increasing demand for phosphorus fertilisers for securing global food production, coupled with finite phosphate rock reserves, is one of the emerging problems in the world. Indeed, phosphate rock is listed as an EU critical raw material, triggering attention to find an alternative source to substitute the use of this limited resource. Cheese whey, characterized by a high content of organic matter and phosphorus, represents a promising feedstock for phosphorus recovery and recycling.

The rapid growth of the livestock sector in some areas of Europe has caused an imbalance between the generation of livestock manure and the availability of agricultural soil for its direct application as a fertilizer. Since the transport of pig slurry to other areas with nutrient-deficient soils is costly from an economic point of view due to its high water content, the application of new technologies for the concentration of this waste is considered key for reducing management costs. Consequently, the main objective of this study was to demonstrate the potential of vibratory shear enhanced processing (VSEP) operated with reverse osmosis membranes to recover nutrients from the liquid fractions of pig slurry (LF-pig slurry) and digestate (LF-digestate) and obtain concentrated fertilizing products.

In this study, the long-term performance and microbial dynamics of an Upflow Anaerobic Sludge Blanket (UASB) reactor targeting sulfate reduction in a SOx emissions treatment system were assessed using crude glycerol as organic carbon source and electron donor under constant S and C loading rates. The reactor was inoculated with granular sludge obtained from a pulp and paper industry and fed at a constant inlet sulfate concentration of 250 mg S-SOL and a constant C/S ratio of 1.5 ± 0.

Flue gases contain SO and NO that can be treated together for elemental sulphur recovery in bioscrubbers, a technology that couples physical-chemical and biological processes for gaseous emissions treatment in a more economic manner than classical absorption. Sequential wet absorption of SO and NO from flue gas is thoroughly studied in this work in a two-stage bioscrubber towards elemental sulphur valorisation pursuing reuse of biological process effluents as absorbents. The optimal operating conditions required for SO and NO absorption in two consecutive spray absorbers were defined using NaOH-based absorbents.

Respirometry was used to reveal the mechanisms involved in aerobic biological sulfide oxidation and to characterize the kinetics and stoichiometry of a microbial culture obtained from a desulfurizing biotrickling filter. Physical-chemical processes such as stripping and chemical oxidation of hydrogen sulfide were characterized since they contributed significantly to the conversions observed in respirometric tests. Mass transfer coefficient for hydrogen sulfide and the kinetic parameters for chemical oxidation of sulfide with oxygen were estimated.

Healthy infants during the first year of life often have multiple functional gastrointestinal symptoms such as colic, regurgitation and constipation. The usual fuzziness and/or crying at this stage of life is interpreted as digestive discomfort or pain, and the corresponding concerns result in unsuitable behaviors as overeating, interruption of breastfeeding, multiple changes of formulas, innumerable queries and unnecessary medications. The aim of this paper is to update knowledge on the pathophysiology of the most common functional gastrointestinal dis orders, in order to avoid over diagnosis and select the most appropriate therapeutic approach and convenient nutritional interventions.

Biotrickling filters for biogas desulfurization still must prove their stability and robustness in the long run under extreme conditions. Long-term desulfurization of high loads of H2S under acidic pH was studied in a lab-scale aerobic biotrickling filter packed with metallic Pall rings. Reference operating conditions at steady-state corresponded to an empty bed residence time (EBRT) of 130s, H2S loading rate of 52gS-H2Sm(-3)h(-1) and pH 2.

Anoxic respirometry was applied to characterize a sulfide-oxidizing nitrate-reducing (SO-NR) culture obtained from an anoxic biogas desulfurizing biotrickling filter treating high loads of H2S. Immobilized biomass extracted from the biotrickling filter was grown in a suspended culture with thiosulfate as electron donor to obtain the biomass growth yield and the S2O3(2)(-)/NO3(-) consumed ratio. Afterward, respirometry was applied to describe thiosulfate oxidation under anoxic conditions.

Monitoring the biological activity in biotrickling filters is difficult since it implies estimating biomass concentration and its growth yield, which can hardly be measured in immobilized biomass systems. In this study, the characterization of a sulfide-oxidizing nitrate-reducing biomass obtained from an anoxic biotrickling filter was performed through the application of respirometric and titrimetric techniques. Previously, the biomass was maintained in a continuous stirred tank reactor under steady-state conditions resulting in a growth yield of 0.

Autotrophic denitrification is a suitable technology to simultaneously remove oxidised nitrogen compounds and reduced sulphur compounds yielding nitrogen gas, sulphur and sulphate as the main products. In this work, several batch tests were conducted to investigate the cross effect of temperature, pH and free ammonia on the autotrophic denitrification. Denitrification efficiencies above 95% were achieved at 35°C and pH 7.

Article Synopsis
  • The study investigated the prevalence of celiac disease (CD) in children across five urban districts in Argentina, as no prior data existed.
  • Researchers analyzed serum samples from 2,219 children, aged 3-16, using serological tests to detect CD and proposed biopsies for further confirmation.
  • The study found a prevalence of 1.26% with a notable female predominance, highlighting a need for increased awareness and early testing for celiac disease among pediatric populations to prevent complications.
