Intradialytic Parenteral Nutrition in Patients on Hemodialysis: A Multicenter Retrospective Study.

Background And Objective: To evaluate the effectiveness and safety of intradialytic parenteral nutrition (IDPN) on different nutritional outcomes.

Methods: This was a retrospective analysis for a "routinely collected data bank" in a multicenter cohort, conducted on consecutive malnourished or at-risk of malnutrition patients with chronic kidney disease on hemodialysis who underwent IDPN with a three-in-one parenteral nutrition formula for a period ≥ 2 weeks. The primary endpoint was the mean change in the malnutrition inflammation score (MIS) score between baseline and the last follow-up visit on IDPN.

Biorefinery of waste activated sludge: Nutrient recovery and microbial lipid production by Yarrowia lipolytica.

The rising generation of waste activated sludge (WAS) demands a fundamental shift towards resource reuse and recovery. The conventional methodologies used to manage this by-product derived from wastewater treatment plants are increasingly constrained due to stringent regulatory measures aimed at mitigating its adverse impacts on the environment and public health. Therefore, this work evaluated a promising strategy for the efficient management of WAS, transforming it into a valuable renewable source to produce high-value-added compounds, such as lipids and a slow-release fertilizer (struvite).

Predictors of mental health in healthcare workers during the COVID-19 pandemic: The role of experiential avoidance, emotion regulation and resilience.

Aims: This study explores the mediational role of resilience, experiential avoidance and emotion regulation in the levels of anxiety, depression and posttraumatic stress disorder (PTSD) of healthcare workers during the COVID-19 pandemic. Additionally, we explored the association of such levels with personal and professional variables.

Design: Cross-sectional study.

Hydrolyzed sewage sludge as raw bio-based material for hermetic bag production.

This study aimed to assess the potential of sewage sludge, a significant residue of wastewater treatment plants (WWTPs), as a sustainable resource for producing a bio-based material for hermetic bags (BMHB), in order to reduce the dependency on petroleum-derived plastics. The approach involved the application of thermal hydrolysis to solubilize sewage sludge, and it systematically examined critical process parameters, including temperature (120-150 °C), residence time (1-4 h), and medium pH (6.6-10).

Risk Factors for Detection in Commercial Layer Flocks in Spain.

Trends in human infections are assumed to be related to the distribution of the pathogen in the animal reservoir/food products, and cases in humans are most often linked to poultry and poultry products (eggs, meat). Therefore, ongoing national control programs (NCPs) in European Union Member States have the objective of monitoring and reducing its prevalence in commercial poultry flocks. Results from NCPs have shown certain factors (housing systems, season of sampling and if sampling is conducted by food business operators (FBOps) or competent authorities (CAs), among others) can influence detection rates, but associations are often not consistent.

The religious faith item of the Spanish Posttraumatic Growth Inventory (PTGI) and its Short Form (PTGI-SF): challenges and solutions.

The Posttraumatic Growth Inventory (PTGI) and its Short Form (PTGI-SF) are two instruments highly used in research on posttraumatic growth. They include a religious growth item that has been demonstrated to be problematic in cultures that are not very religious. Previous research has addressed this issue in other countries, but no attention has been paid to this critical problem in Spanish samples.

Valorisation of the residual aqueous phase from hydrothermally liquefied black liquor by persulphate-based advanced oxidation.

Hydrothermal liquefaction of Kraft black liquor is a promising method for the production of valuable organic chemicals. However, the separation of the biochar and biocrude leaves a residual aqueous phase in large volumes, which needs to be properly managed to make the process profitable. In this work, the persulphate-based advanced oxidation was assessed, for the first time ever, as a pretreatment of this aqueous phase to reduce its content of phenolic compounds and alcohols, which hinder further valorisation strategies.

Designing learning environments for promoting young people's constructive coping with climate change.

This chapter first summarizes how the consequences of global climate change (GCC) can harm young people's well-being through physical health impacts and awareness of GCC. We then outline how youth may cope with GCC by denying the problem, distancing themselves from it, or taking individual actions. However, the coping strategy shown to have the best mental well-being outcomes relates to collective actions and agency.

The effects of nature-based interventions on individuals' environmental behaviors: protocol for a systematic review of controlled trials.

Background: The paper presents the rationale and methods of the planned systematic review to understand the effects of nature-based interventions on individuals' environmental behaviors. There is ample evidence that experiences in nature not only enhance human well-being but also help promote people's pro-environmentalism. Nevertheless, synthesized evidence regarding the effects of nature-based interventions on individuals' environmental behaviors is lacking.

Advanced thermal hydrolysis for biopolymer production from waste activated sludge: Kinetics and fingerprints.

Waste activated sludge (WAS) is the main residue of wastewater treatment plants, which can be considered an environmental problem of prime concern due to its increasing generation. In this study, a non-energetic approach was evaluated in order to use WAS as a renewable resource of high value-added products. For this reason, WAS was treated by thermal hydrolysis, HO oxidation and advanced thermal hydrolysis (ATH) promoted by HO.

Structure of the humic acid-like compounds of raw and hydrothermally treated sewage sludge.

Humic acids are of great interest in many fields; however, they are inhibitors of fermentative processes applied to hydrothermally treated sewage sludge. Hence, the structure and composition of soluble and bound humic acid-like fractions from raw and hydrothermally treated sewage sludge were studied. Lipid, polysaccharide, protein and aromatic fractions were identified, as well as a high nitrogen content (7-10 %) and low solubility in alkaline media.

Characterization and reuse of waste from the magnesium nitrate fertilizer industry.

Currently, liquid fertilizers are considered strategic products in the sector, particularly those with nitrogen and magnesium in their composition. During their synthesis, the generated muddy and sticky residue is usually managed as a toxic waste because its properties and feasible valorization methods have not yet been studied. For the first time, this residue has been thoroughly characterized, and, on the results obtained, its possible reuse options have been discussed.

Comparison of Patients' Phenotypes, Guideline-Directed Recommendations Compliance and Rates of Cardiotoxicity between Caribbean and United States Cardio-oncology Programs.

Background: Little is known about the characteristics of oncological patients, cancer therapy-induced cardiotoxicity, and guidelines-directed interventions in the Caribbean; analysis of cardio-oncology services may shed light on this and clarify links between ethnicity, cultural, and local socioeconomic factors.

Objectives: This study compared patients' phenotypes, adherence to guidelines recommendations, and patterns of cardiotoxicity between two cardio-oncology programs: one in the Dominican Republic (DR) and the other in Chicago IL, United States (US).

Methods: Patients being considered for or treated with potentially cardiotoxic drugs were followed before, during, and after chemotherapy through both cardio-oncology clinics, where we recorded and compared clinical, demographic, and echocardiographic data.

BOF slag as a new alkalizing agent for the stabilization of sewage sludge.

This study assessed, for the first time ever, the use of basic oxygen furnace (BOF) slag as alkalinizing material during the sludge conditioning, as an environmentally-friendly alternative to CaO and other conventional alkalis. Its effects on the dewatering, solubilisation and stabilization of sewage sludge were studied, testing increasing dosages of BOF from 0 to 6 gBOF/gTSS at room temperature and under constant mechanical agitation was evaluated. Results revealed that the addition of BOF slag to sewage sludge produced similar degrees of solubilisation to those obtained using lime, reaching a maximum of 34% of total COD for 3.

Prediction of post-traumatic growth in the face of the COVID-19 crisis based on resilience, post-traumatic stress and social participation: A longitudinal study.

The COVID-19 crisis has generated a severe and negative psychological impact worldwide. Despite this, it is also possible to experience post-traumatic growth (PTG). This study aimed to longitudinally explore the prevalence of PTG in the Spanish population and test a predictive model for PTG from resilience, post-traumatic stress symptoms (PTSS), and participation in social activities.

Genomic characterization of multidrug-resistant serovar Kentucky ST198 isolated in poultry flocks in Spain (2011-2017).

Kentucky is commonly found in poultry and rarely associated with human disease. However, a multidrug-resistant (MDR) . Kentucky clone [sequence type (ST)198] has been increasingly reported globally in humans and animals.

The posttraumatic growth inventory-short form (PTGI-SF): A psychometric study of the spanish population during the COVID-19 pandemic.

People can experience posttraumatic growth (PTG) when faced with potentially traumatic events. One of the most widely-used instruments to measure PTG is the Posttraumatic Growth Inventory-Short Form (PTGI-SF). However, it has not been validated for the Spanish population.

Mortality in Hemodialysis Patients with COVID-19, the Effect of Paricalcitol or Calcimimetics.

Background: In COVID-19 patients, low serum vitamin D (VD) levels have been associated with severe acute respiratory failure and poor prognosis. In regular hemodialysis (HD) patients, there is VD deficiency and markedly reduced calcitriol levels, which may predispose them to worse outcomes of COVID-19 infection. Some hemodialysis patients receive treatment with drugs for secondary hyperparathyroidism, which have well known pleiotropic effects beyond mineral metabolism.

Heavy metal solubilisation during the hydrothermal treatment of sludge.

The present study analyses the combined effects of temperature (from 160 to 200 °C), and, for the first time ever, type of atmosphere (oxidising or inert) and pressure (from 60 to 100 bar) on the solubilisation of heavy metals during the hydrothermal treatment of wet no-diluted sewage sludge. Results revealed that Cd, Pb, Al and Fe were hardly affected by neither the atmosphere nor temperature, remained almost completely in the solid phase during all the hydrothermal treatments tested; while Cr, Ni, Cu and Zn were partially solubilised, being this solubilisation favoured by the presence of an oxidising atmosphere. In contrast, initial dissolved Hg was partially precipitated under both types of atmosphere, although it was re-dissolved after 30 min under an inert atmosphere.

Becoming in Resistance: The (Un)Creative Relation Between Non-heterosexual Identity and Psychological Suffering.

This article aims at theorizing a creative and processual theory of non-heterosexual identity. It will be argued that, so far, scholars have tended to theorize non-heterosexual identity from a monologic perspective, which establishes one-sidedly a casual and/or unproblematic relation between the emergence of forms of psychological suffering and the development of a non-heterosexual identity. Although it must be recognized that such a claim is important at a political level, at a subjective level, it leaves non-heterosexual people destined to be flooded by distressing and painful emotional states.
