The genomic diversity and population structure of marine species represents a complex mosaic shaped by historical and contemporary environmental seascape features that maintain or alter it over time. The Gulf of California (GC) is an interior sea with a dynamic history during its formation and a contemporary environmental and oceanographic complexity; hence, it is a suitable system to test the effect of historical and contemporary factors on genomic diversity in marine species. We investigated the genomic seascape of the redhead goby (Elacatinus puncticulatus; Ginsburg, 1938), a cryptobenthic marine fish, to gain insights into the historical and contemporary drivers shaping its population structure in the GC. A total of 4802 SNPs markers were analysed, with 3775 loci classified as neutral markers and 27 as outlier markers potentially under selection. Both markers demonstrated population structure, with the neutral markers showing two main groups corresponding to northern and southern locatities. The outlier markers identified an additional genetic group emerging in the central area of the sampled localities. Genetic differentiation between the North and South regions and historical demographic simulations was consistent with ancient divergence (1.04 Mya) and secondary contact (0.15 Mya). The genomic environmental association analysis revealed a possible adaptive scenario linked to ocean temperature. The study highlights the importance of historical events, contemporary environmental factors, and oceanographic circulation in shaping the genetic structure of E. puncticulatus populations in the GC., (© 2025 John Wiley & Sons Ltd.)

This study aimed to evaluate the prognostic significance of programmed cell death (PD)-1/PD-ligand 1 (PD-L1), PD-ligand 2 (PD-L2), and Fibroblast growth factor receptor 3 (FGFR3) expression in bladder cancer (BC). Material and Methods A retrospective study was conducted on BC patients who underwent transurethral resection (TUR) between 2005 and 2014. Of the initial 136 patients, 31 were excluded for not meeting the inclusion criteria, leaving 105 cases for the final analysis. The mRNA levels of PD-1/PD-L1/PD-L2 and FGFR3 were assessed using quantitative reverse transcription PCR and NanoString technology. Results High expression of PD-1 and its ligands (PD-L1/PD-L2) showed a strong correlation with each other and was associated with poor clinical outcomes, including higher tumor stage, grade, and cancer-specific mortality (p<0.001). Conversely, high FGFR3 expression was associated with improved survival and more favorable clinicopathological features. Interestingly, an inverse relationship was observed between FGFR3 and PD-1 (p=0.032) and PD-L1 (p=0.016) expression. High mRNA expression profiles of PD-1, PD-L1, PD-L2, and low FGFR3 expression were associated with worse cancer-specific survival (p < 0.001). Multivariate analysis revealed that advanced stage, low FGFR3 expression, and high PD-L2 expression are independent predictors of poor prognosis in BC patients. Conclusions Our findings suggest that elevated levels of PD-1, PD-L1, and PD-L2, combined with reduced FGFR3 expression, may assist in identifying patients with poor outcomes and highlight their potential as prognostic biomarkers in bladder cancer., (S.

Background: Guidelines recommend switching the glomerular filtration rate (eGFR) estimation from the CKiD-U25 to the CKD-EPI formula at age 18. We investigated how this would affect chronic kidney disease (CKD) classification., Methods: Serum creatinine was enzymatically measured in 1061 samples from 914 community-based 10-23-year-olds from Tlaxcala, Mexico, a region where urinary biomarkers demonstrated early kidney damage associated with exposure to inorganic toxins in a pediatric population. We calculated their eGFR using CKiD-U25, modified Schwartz, the first and modified Pottel full-age spectrum (FAS), and CKD-EPI formulae. Correlation analysis characterized the CKD stage stratified by age and sex., Results: At baseline, the median age was 13 (IQR: 12, 15) years, and 55% were female. Median CKiD-U25 eGFR was 96.9 (IQR: 83.3, 113.3) mL/min/1.73 m 2 , significantly lower than the CKD-EPI eGFR, which was 140.8 (IQR: 129.9, 149.3) mL/min/1.73 m 2 ( p < 0.0001, Wilcoxon rank test). The mean bias was 36.99 ± 12.89 mL/min/1.73 m 2 . Pearson correlation was r = 0.8296 (95% confidence interval 0.0898-0.8474). There was a better correlation between the modified Schwartz (r = 0.9421 (0.9349, 0.9485)) and the Pottel FAS (r = 0.9299 (0.9212, 0.9376)) formulae. Agreement was deficient when the eGFR was >75 mL/min/1.73 m 2 in younger age and female sex. Modified Schwartz identified 281 (26.4%) measurements as having CKD 2 and 3 (2+), U25 identified 401 (37.7%) measurements as having CKD 2+, FAS identified 267 (25.1%) and modified FAS identified 282 (30%) measurements as having CKD 2+, and CKD-EPI identified 51 (4.8%) measurements as having CKD 2+, respectively., Conclusions: In this population, there needed to be better agreement between the various eGFR formulae. CKD-EPI identifies substantially fewer at-risk participants as having CKD.

Purpose: This study aimed to evaluate the effectiveness of an intervention that involved interactions within a simulated health care space to reduce medical fear among children in infant classes., Methods: An experimental study involving 86 children divided into an intervention group and a control group with pre- and postintervention measurements was undertaken. The intervention, known as the Health-Friendly Program, consisted of showing children various scenarios that simulated different medical contexts so that they could interact in them, experiment with the materials and ask questions. Medical fear was evaluated using the Spanish version of the revised "Child Medical Fear Scale", which provides a score of the medical fear level ranging between 0 and 34 points. The pretest and posttest levels of medical fear in the intervention and control groups were compared with Student's t test., Results: The children in the intervention group experienced a significant reduction in fear by 3.21 points (SD: 6.50) compared to the children in the control group. This reduction in fear was shown in all four dimensions of the scale: intrapersonal fears, procedural fears, environmental fears and interpersonal fears., Conclusion: The Health-Friendly Program provides an innovative intervention to reduce medical fear among children based on information, confrontation strategies and simulation scenarios. This study suggests the potential benefit of incorporating educational interventions in schools in collaboration with university and health care simulation centers., (Copyright © 2024 The Authors.

Seascape genomics facilitates integrative research on eco-evolutionary forces, such as migration and natural selection, which shape genomic connectivity and structure and provide critical insights for conservation strategies. The green abalone ( Haliotis fulgens ) is distributed from California, United States, to Baja California Sur, Mexico, and exposed to a latitudinal environmental gradient in the California Current System. This study aimed to investigate genomic population structure and potential local adaptations of green abalone across its distribution. The green abalone exhibits a distinctive neutral genetic structuring influenced by geographic distance and marine currents rather than local adaptations. Analyses using 9100 neutral and 17 outlier SNPs revealed three distinct populations: the North group (California to Ensenada, Baja California), a population on Guadalupe Island, and the South group (coastal locations of the Baja California peninsula). The research underscores the significance of life history traits and larval dispersal in shaping genetic connectivity. Connectivity appears to be influenced by geographic distance on neutral genetic structure, overshadowing natural selection's role. Furthermore, no genome-environment associations to sea surface temperature values were found. Future research should integrate genetic data with ocean circulation modeling to better understand the mechanisms and outcomes of larval dispersal and genetic connectivity. This study emphasizes the importance of both local and binational (USA-Mexico) conservation efforts, suggesting the development of SNP marker panels for traceability and management. Collaborative strategies could serve as models for binational conservation initiatives in other ecoregions, promoting sustainable management and conservation of green abalone populations and other exploited species across national borders., Competing Interests: The authors declare no conflicts of interest., (© 2025 The Author(s).

Intimate partner violence against women (IPVAW) is a global problem, and suicidal behaviour is one of its most serious consequences. However, no study has investigated the spatial overlap between the two. The aim of this paper is to analyse whether there is spatial overlap between IPVAW and suicide-related calls in the same neighbourhoods, and to identify common risk factors. Geocoded data on IPVAW (N = 2060) and suicide-related calls (N = 4916) from the city of Valencia, Spain, between 2019 and 2021 were collected from the 112 emergency service and the Spanish National Police Corps. We used two analytical approaches: (i) a Bayesian spatial Poisson regression modelling analysis to identify the risk factors associated with IPVAW and suicide-related calls; (ii) Bayesian joint spatial modelling to examine the common spatial distribution of these outcomes. Relative risk maps are also displayed and analysed. The study revealed a higher incidence of IPVAW and suicide-related calls in neighbourhoods with lower income and population density, and greater residential instability and immigrant concentration. There was a 70% similarity between high- and low-risk areas for these incidents, with a moderate positive correlation of 0.43. Notably, 98% of IPVAW risk variance was explained by shared factors, while 30% applied to suicide-related calls; high IPVAW risk was also found in peripheral areas, while suicide-related calls were concentrated in the city centre. The findings highlight the need to identify areas with shared risk and neighbourhood characteristics for the development of more effective intervention strategies., (© The Author(s) 2024.

This study aims to explore the challenges and strategies in creating online communities for individuals with diabetes, emphasizing their role in fostering connections among individuals facing similar health conditions. Using a single-case approach, we investigated the design process of a diabetes online community using the classic waterfall model. Participants were recruited from a diabetes local association, and usability was assessed using the System Usability Scale and the think-aloud method. Subsequently, semistructured interviews were conducted to evaluate functionality and user experience. Data collection was conducted from August until December 2023. The development of the community unveiled significant usability challenges, highlighting the need for user feedback and improvement. Ethical considerations, including anonymity, usage conditions, privacy terms, and health information sharing, emerged as critical areas requiring meticulous attention. Furthermore, healthcare professional moderation was deemed essential to ensure a secure environment. Users expressed strong interest in enhanced interaction features and personalized notifications. Although online diabetes communities hold potential for peer support, addressing usability challenges, ethical considerations, and moderation issues is essential. This study emphasizes the ongoing necessity for research to enhance the development of patient communities, ensuring accessibility, mitigating ethical risks, and leveraging nurses as moderators., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Extracranial carotid artery aneurysms (ECAAs) are extraordinarily rare, representing approximately 0.4%-4% of all extracranial artery aneurysms. As medical technology has advanced, new approaches for ECAAs treatment can be performed. Nevertheless, there is currently no consensus on the best therapeutic approach due to the information scarcity., Methods: We performed a systematic review of all published ECAA cases in Scopus, Medline, Web of Science, and Google Scholar to retrieve all available studies up to March 2024., Results: Eighty-eight studies reporting on a total of 359 patients presenting ECAAs were included. The mean age at diagnosis was 53 years. Most patients were male (58.4%). The primary presenting symptoms were pulsatile mass (31.2%), ischemia (24.7%), pain (9.75%), and dizziness (8.36%). Overall, the leading etiologies of aneurysms were atherosclerosis (34.2%), trauma (10%), and vasculitis (5.57%). Surgery was performed in 68.5% of patients, 26.7% underwent endovascular procedures, and 3.9% received conservative management., Conclusions: ECAAs are a rare clinical condition. However, a great percentage of patients could present with ischemic symptoms. Similarly, cardiovascular risk factors present as the most prevalent comorbid conditions associated with these vascular aberrancies. With this systematic review, we seek to provide insight into extracranial carotid aneurysms, identifying areas of opportunity in both the diagnosis and management of this pathology and the standardization of clinical reporting and case classification. These findings underscore the need for future research to improve the understanding and approach to this complex clinical condition., (Copyright © 2024. Published by Elsevier Inc.)

Purpose: This study aimed to establish the content validity of the proposed nursing diagnosis (ND) "Adult Disuse Syndrome" and all its components., Method: This is an exploratory descriptive study of diagnostic content validation under Fehring's proposal. Forty three expert nurses with clinical, teaching, and research experience analyzed the components of the diagnosis. The representativeness and relevance of the components of the diagnosis under study were evaluated through a Likert-type questionnaire. Data distribution analysis was carried out, and the components were validated if their content validity index (CVI) was over 0.80. The overall CVI was obtained for the clinical indicators., Findings: A total of 12 defining characteristics (DCs) were validated, 3 etiological factors were highly related, 6 risk populations were confirmed, and 11 conditions were considered associated. Most validated DCs refer to the physical dimension, but those focusing on the psychological and social dimensions were also validated. The etiological factors were related to the effects of immobility. The risk populations were validated in different contexts or situations, and associated conditions were mainly oriented toward chronic conditions., Conclusions: This study validated the content of the elements of the proposed ND "Adult Disuse Syndrome." These were considered relevant and appropriate by both academic and clinical experts., Implications for Nursing Practice: The content validation by experts of the components of the ND "Adult Disuse Syndrome" provides nurses with a tool for the identification of the phenomenon that exceeds the risk and occurs frequently in patients exposed to the effects of immobility. At the same time, it will guide the results pursued in the care plan and the application of the respective nursing and interdisciplinary interventions that favor the reduction of the complications derived from disuse., (© 2025 The Author(s).

Unhealthy lifestyles risk factors, such as smoking, alcohol consumption, physical inactivity, poor diet, and obesity, have been associated with a higher risk of all-cause and cause-specific mortality. However, composite score of these unhealthy behaviours has not been considered, particularly in Latin American populations. Herein, we examined the association of lifestyle risk factors score with all-cause and cause-specific mortality in Mexican adults. A total of 159,517 adults from the Mexico City Prospective Study (MCPS) were included. Data on sociodemographic, lifestyle risk factors and medical histories was collected through a self-reported baseline questionnaire in a census-style door-to-door interviews. Lifestyle risk factors assessment was based on five modifiable lifestyle risk factors and their respective cut-off points according to current health recommendations, including obesity, physical inactivity, tobacco, alcohol consumption and fruits and vegetables intake. Multivariable Cox regression models were used to estimate the associations of lifestyle risk factor score (ranging from 0 to 5) with all-cause and cause-specific mortality (cardiovascular disease, renal or hepatobiliary diseases, diabetes, respiratory diseases, cancer and all-cause mortality). We excluded the first 2, 5, 10, and 15 years of follow-up to account for reverse causation bias. We found a high prevalence (77%) of Mexican adults, with two or more lifestyle risk factors. Hazard ratio for respiratory diseases and renal or hepatobiliary diseases were 1.86 (95%CI: 1.45-2.39) and 2.00 (95%CI: 1.60-2.52) comparing participants with 4-5 lifestyle risk factors vs. those with none. For all-cause mortality, participants with 4-5 lifestyle risk factors had a 49% (HR: 1.49; 95%CI: 1.03-2.16) higher risk as compared to participants with none. The magnitude of the associations increased as the exclusion of follow-up time increased after 2, 5, 10 and 15 years. There was a positive association between the number of lifestyle risk factors and all-cause and cause-specific mortality, showing the highest rate of respiratory, renal or hepatobiliary and all-cause mortality among participants with 4-5 lifestyle risk factors. After accounting for reverse causation, associations were stronger., Competing Interests: Declarations. Competing interests: The authors declare no competing interests.

Aim: To analyze the scope of nursing practice in medical-surgical and intensive care units in the Spanish context and its relationship with individual characteristics of nurses and their work environment., Methods: A cross-sectional observational study was carried out in 29 medical-surgical hospitalisation units and five intensive care units for adults in the public network of Navarre. The main variable, nurses' scope of practice, was measured using the Spanish version of the D'Amour questionnaire. Descriptive and inferential statistics were used to analyse the data, with a significance level of 0.05., Results: A total of 310 nurses participated in the study, and the results showed acceptable levels of nursing scope of practice. Age and working in intensive care units were significant factors in identifying differences in nurses' scope of practice activities. The correlation analysis revealed a statistically significant association between age and the likelihood of expressing lower scores in the dimension "Patient- and family-centered care." In contrast, younger nurses exhibited significantly lower scores in the "Quality of care and patient safety" dimension., Conclusions: To address the shortage of nurses in health systems, it is essential to understand the scope of nursing practice. The challenge is not only to increase the number of nurses but also to ensure that they are working in the full range of their professional roles., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare., (Copyright © 2024 The Author(s).

Malaria remains a significant health threat in tropical and subtropical regions. The immune response to Plasmodium falciparum involves both humoral and cellular components, including phagocytosis by neutrophils. However, observing phagocytosis through light microscopy is uncommon. This report presents a rare case of falciparum malaria in a Ghanaian twin, highlighting intracellular P. falciparum forms in neutrophils. Two 7-year-old male twins from Ghana were admitted with fever, vomiting, and abdominal pain. They tested positive for P. falciparum infection via rapid diagnostic tests and blood smears. Child 1 displayed significant neutrophilia and intracellular parasites, including trophozoites, merozoites, and a potential schizont, within neutrophils. Child 2 showed no phagocytosis but exhibited other signs of systemic inflammation and hemolysis. Both children were treated successfully with piperaquine tetraphosphate/artenimol (Eurartesim®). This case provides rare microscopic evidence of P. falciparum phagocytosis by neutrophils, suggesting prior antibody development in the patient. While the findings highlight the role of phagocytosis in parasite clearance, the absence of similar observations in the second twin raises questions about individual immune responses and genetic factors. Further research is needed to explore the underlying biological mechanisms., Competing Interests: Declaration of competing interest The authors have no relevant financial or non-financial interests to disclose., (Copyright © 2025 Elsevier B.V.

Cardiometabolic risk factors such as obesity, raised blood pressure, high blood glucose and dyslipidemia are emerging health concerns worldwide. Therefore, the aim of this study was to estimate the combined association between physical activity and depressive symptoms with cardiometabolic risk factors in Chilean adults. Data was obtained from the National Health Survey of Chile 2016-2017, with a sample of 5995 adult participants. Assessment of Physical activity and depressive symptoms were done using the Global Physical Activity Questionnaire (GPAQ) and the CIDI ShortForm (CIDI-SF), respectively. Multivariable logistic regression was performed to estimate the combined association of physical activity and depressive symptoms with cardiometabolic risk factors. Participants in the category ≥ 150 min/Depressive symptoms had the highest prevalence of overweight (OR: 1.55, 95% CI: 1.17-2.05), obesity (OR: 1.97, 95% CI: 1.49-2.59) and high waist circumference (OR: 1.63, 95% CI: 1.39-1.92). Participants in the < 150 min/No depressive symptoms category had a lower prevalence of overweight/obesity (OR: 0.68, 95% CI: 0.60-0.78) and a 25% reduced high triglycerides prevalence, in comparison with the active category with no depressive symptoms. There is a positive association between depressive symptoms and overweight, obesity and waist circumference among subjects that complete physical activity recommendations but have depressive symptoms., Competing Interests: Declarations.

The current quality control of the dry-curing process in Iberian ham is performed with an olfactory evaluation by ham experts. The present study proposes to monitor the dry-curing process of Iberian ham using an objective analytical methodology that involves non-destructive sampling of the subcutaneous fat of the hams and a volatile profile analysis using gas chromatography-ion mobility spectrometry. Thirty-eight 100% Iberian acorn-fed hams were examined in total, with eighteen hams monitored during the post-salting stage and twenty during the drying-maturation stage. A total of 164 markers were detected in the samples monitored during the post-salting stage, whereas 276 were detected in the hams monitored during the drying-maturation stage. The study of the trends observed in the intensities of the markers throughout the curing process enabled the detection of potential indicators of the end of the post-salting stage. Thus, representative intensity thresholds were established for some markers (3-methylbutanal, pentanal, hexanal, ( E )-octen-2-al, 2-hexen-1-ol and heptan-1-ol) to determine the optimal point to specify the end of the post-salting process for hams. These findings provide an objective tool to support the traditional sensory evaluation currently performed in the industry.

Background: Anthropogenic vanadium (V) emissions and exposure in the general population have recently increased. Experimental studies have shown that V is a nephrotoxic agent, but little is known about its effects on human kidney health. This work evaluated the association between urinary V concentrations with early kidney damage biomarkers and function in a pediatric population without any disease diagnosed., Methods: A cross-sectional study was carried out and included 914 healthy subjects and determined urinary V concentrations, glomerular filtration rate (eGFR), albumin-creatinine ratio (ACR), and the presence of kidney injury molecule 1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) in urine. We evaluated the V effect using linear and logistic regression models adjusted by confounders., Results: Subjects found in the second and third tertiles of V showed an increase in urinary log-NGAL levels (βT2 vs. T1 = 0.39; 95% CI 0.14, 0.64, and βT3 vs. T1 = 1.04; 95% CI 0.75, 1.34) and log-KIM-1(βT2 vs. T1 = 0.25; 95% CI 0.04, 0.45 and βT3 vs. T1 = 0.39; 95% CI 0.15, 0.63); in addition, subjects in the third tertile had a positive and significant association with ACR (ORT3 vs. T1 = 1.96; 95% CI 1.29, 2.97) and increased in eGFR (βT3 vs. T1 = 3.98, 95% CI 0.39, 7.58), compared with subjects in the first tertile., Conclusions: Our study reports the effect of V on kidney markers in a healthy pediatric population. It could be related to tubulointerstitial lesions and function abnormalities., Competing Interests: Declarations.

This study examines the global evolution of sow productivity, with a particular focus on Spain. The analysis is based on key performance metrics such as piglets weaned per sow per year (PWSY), prolificacy, and pre-weaning mortality, utilizing data from literature reviews, the InterPIG, and BDporc ® databases. Globally, significant advancements in genetic selection and management practices have led to productivity increases across major pig-producing countries, with notable improvements in prolificacy. However, higher prolificacy has been accompanied by rising piglet mortality rates during lactation, posing sustainability challenges. In Spain, the average productivity of commercial sows increased from 23.78 PWSY in 2009 to 29.45 PWSY in 2023, while Iberian sows reached an average of 17.44 PWSY. Despite these gains, Spain's figures remain slightly below the European Union average. The study highlights the need for new benchmarks, such as non-productive days, piglet survival, and sow longevity, to more accurately assess farm efficiency. These indicators, combined with considerations for animal welfare and environmental sustainability, are crucial for addressing current challenges such as piglet mortality, sow culling, and the carbon footprint. The findings emphasize the importance of adopting comprehensive management strategies that balance productivity with growing social and environmental demands on the swine industry.

This study aims to validate the five repetition sit to stand test (5R-STS) test as a measure of strength and functionality in adolescents and adults with intellectual disabilities (ID). The sample was made up of 159 subjects with ID (85 adolescents and 74 adults) of both sexes, with average age of 18.36 (5.26) years, belonging to four special educational centers from Santiago, Chile. Absolute (AHGS) and relative (RHGS) handgrip strength and countermovement jump (CMJ) were considered as muscle strength evaluation tests. The timed up and go (TUG) and agility test 4 × 10 m were considered as functional tests. Spearman and intraclass correlations, as well as Bland-Altman plots were used to establish the respective correlations. The average values obtained in the 5R-STS test (s) in adolescents were 6.55 and 7.24, while in adults they were 6.82 and 7.17 for men and women, respectively. Significant correlations (p = < 0.05) are established between the 5R-STS test with AHGS (r= -0.48) and RHGS (r= -0.54), CMJ (-0.53), 4 × 10 m test (-0.50) and TUG (-0.49), as well as in the analysis of agreement between 5R-STS and the TUG (ICC = 0.74) and agility 4 × 10 m (ICC = 0.61) tests, both in adolescents and adults of both sexes. The 5R-STS test is a valid, simple and safe tool to evaluate general and lower extremity muscle strength. Its use is suggested as a simple measure for monitoring functional capacity by professionals in educational and health contexts for the adolescent and adult population with ID., Competing Interests: Declarations.

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). In EoE patients, esophageal biopsies were taken before (pre) and after (post) an 8-week PPI treatment, determining the histologic response. Eosinophil count PostPPI was used to classify the patients: ≥15 eosinophils/hpf as non-responders (non-responder) and < 15 eosinophils/hpf as responders (R). Protein signature was determined and differentially accumulated proteins were characterized to identify altered biological processes and signaling pathways., Results: Comparative analysis of differentially accumulated proteins between groups revealed common signatures between three groups of patients with inflammation (responder-PrePPI, non-responder-PrePPI, and non-responder-PostPPI) and without inflammation (controls and responder-PostPPI). PPI therapy almost reversed the EoE specific esophageal protein signature, which is enriched in pathways associated with inflammation and epithelial barrier function, in responder-PostPPI. Furthermore, we identified a set of candidate proteins to differentiate responder-PrePPI and non-responder-PrePPI EoE patients before treatment., Conclusion: These findings provide evidence that PPI therapy reverses the alterations in esophageal inflammatory and epithelial proteins characterizing EoE, thereby providing new insights into the mechanism of PPI clinical response. Interestingly, our results also suggest that PPI response could be predicted at baseline in EoE., (© 2024 The Author(s).

Background/objectives: Fats, although essential for the proper functioning of the body, have been linked to an increased risk of developing chronic diseases, especially cardiovascular disease. The aim of this study was to evaluate the intake of total fat and its components (saturated, monounsaturated, polyunsaturated, and trans fats) in men and women aged 15 to 65 years of the urban population in eight Latin American countries., Methods: Survey data were collected from the Latin American Study of Nutrition and Health (ELANS, by its acronym in Spanish), an epidemiological study, including 9218 subjects from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela., Results: In general, 76.2% of the subjects consumed fat within normal ranges (20-35% of the total caloric value (TCV)). When analyzing its components, a majority of the subjects consumed saturated and polyunsaturated fats within the recommended ranges. However, 94.5% of the population does not comply with the recommended maximum intake of monounsaturated fatty acids (MUFA) (10-20%), and only 57.5% comply with the intake recommendation for trans fatty acids (TRANS) (0-2%). Likewise, on average, women had a significantly higher intake of all types of fat compared to men. Finally, the average fat intake by age indicates that regardless of the age range, the consumption of all fats except MUFA and TRANS are within the recommended ranges, with MUFA being slightly below and TRANS above., Conclusions: Even though the fat intake of the population falls within the recommended range, it is necessary to improve the quality by favoring the consumption of MUFA-rich foods regionally accepted, such as avocados, and reducing the consumption of TRANS.

Children today are immersed in electronic technology shortly after birth as they now begin regularly watching television earlier than they did in the past. Many new programs geared towards infants contain lots of lights, color, and sounds, which may constitute a form of sensory overstimulation (SOS) that leads to cognitive and behavioral changes in children and adolescents. Here, we examined the impact of early life SOS exposure on later life behavioral and cognitive function in rodents by exposing developing male and female rats to excessive audiovisual stimulation from postnatal days (PND) 10-40 and assessing anxiety-like behavior, social motivation, compulsive behavior, and spatial learning/cognition from PND 50-60. To evaluate potential SOS effects on hypothalamic-pituitary-adrenal (HPA)-axis function, levels of the stress hormone corticosterone (CORT) were measured at 3 timepoints (e.g., PND 23, 41, 61) post-SOS exposure. Sensory overstimulated males exhibited reduced anxiety-like and compulsive behavior compared to controls, whereas females exhibited reduced social motivation but enhanced spatial learning/cognition compared to controls. No differences in baseline CORT levels were found at any age tested, suggesting no impact of early life SOS on later life basal HPA-axis function. Our results demonstrate sex-specific effects of early life SOS on distinct behavioral domains in early adult rats., Competing Interests: Declarations Competing interests The authors declare no competing interests., (© 2024.

The main objective of this research is to conduct an experimental investigation of the bimetallic material formed by 316LSI stainless steel and S275JR structural steel, produced via hybrid wire arc additive manufacturing technology with cool metal transfer welding and machining, and with the objective of being able to reduce the industrial cost of certain requirements for one of the materials. A methodological investigation has been carried out starting with welding beads of 316LSI on S275JR plates, followed by overlapping five beads and conducting final experiments with several vertical layers, with or without intermediate face milling. The results achieved optimal bead conditions for wire speeds of 4 m/min and 5 m/min at a travel speed of 400 mm/min. Overlap experiments show that the best deposition results are obtained with an overlap equal to or greater than 28%. Cooling time does not significantly influence the final geometry of the coatings. Regarding metallographic analysis, the filler material presents an austenitic columnar structure. In the base material, a bainitic structure with inferred grain refinement was detected in the heat-affected zone. An increase in hardness is observed in the heat-affected zone. In the results obtained from the tensile tests of the bimetallic material, an increase in mechanical strength and yield strength is observed in the tested specimens.

Aim: Epigenetic regulation of the key inflammatory genes plays a crucial role in controlling monocyte/macrophage-mediated local and systemic responses to bacterial challenges. However, it has not been addressed in apical periodontitis (AP). We aimed to explore the methylation pattern of the TNF-α gene promoter and its association with the inflammatory phenotype of peripheral blood monocytes from individuals with AP and controls., Methods: A cross-sectional study was conducted, including otherwise healthy individuals with AP (n = 25) and controls (n = 29). Monocytes were isolated from the volunteer's blood samples using a Ficoll gradient followed by negative immunoselection. RNA and DNA were extracted. The DNA methylation profiles of the TNF-α gene promoter region were analyzed using bisulfite sequencing PCR. The mRNA expression levels of DNA methyltransferases 3a (DNMT3a) and Ten Eleven Translocation enzymes 1(TET1) were assessed by qPCR. A fraction of primary monocytes was also cultured for 24 h, and the supernatant was collected to measure cytokine levels through a Luminex assay. Generalized structural equation models (GSEM) evaluated the association between AP, DNA methylation, and TNF-α protein expression controlled for potential covariates. Models included the effect of the methylation of TNF-α gene promoter as a mediator of the association between AP and TNF-α protein expression levels., Results: Monocytes from AP individuals exhibited a heightened secretion of TNF-α and IL-1β and hypomethylation of the TNF gene promoter (p < .05). AP diagnosis was associated with the TNF-α gene promoter´s hypomethylated profile and enhanced pro-inflammatory cytokine levels, while lower methylation of the gene promoter region and -163 CpG single site mediated TNF-α overexpression (p < .05)., Conclusions: DNA hypomethylation at the TNF-α gene mediates a proinflammatory phenotype in monocytes from AP patients, supporting a role in the systemic response., (© 2024 British Endodontic Society.

Bisphenol A (BPA), a synthetic chemical widely used in the production of polycarbonate plastic and epoxy resins, has been associated with a variety of adverse effects in humans including metabolic, immunological, reproductive, and neurodevelopmental effects, raising concern about its health impact. In the EU, it has been classified as toxic to reproduction and as an endocrine disruptor and was thus included in the candidate list of substances of very high concern (SVHC). On this basis, its use has been banned or restricted in some products. As a consequence, industries turned to bisphenol alternatives, such as bisphenol S (BPS) and bisphenol F (BPF), which are now found in various consumer products, as well as in human matrices at a global scale. However, due to their toxicity, these two bisphenols are in the process of being regulated. Other BPA alternatives, whose potential toxicity remains largely unknown due to a knowledge gap, have also started to be used in manufacturing processes. The gradual restriction of the use of BPA underscores the importance of understanding the potential risks associated with its alternatives to avoid regrettable substitutions. This review aims to summarize the current knowledge on the potential hazards related to BPA alternatives prioritized by European Regulatory Agencies based on their regulatory relevance and selected to be studied under the European Partnership for the Assessment of Risks from Chemicals (PARC): BPE, BPAP, BPP, BPZ, BPS-MAE, and TCBPA. The focus is on data related to toxicokinetic, endocrine disruption, immunotoxicity, developmental neurotoxicity, and genotoxicity/carcinogenicity, which were considered the most relevant endpoints to assess the hazard related to those substances. The goal here is to identify the data gaps in BPA alternatives toxicology and hence formulate the future directions that will be taken in the frame of the PARC project, which seeks also to enhance chemical risk assessment methodologies using new approach methodologies (NAMs).

Aim: To evaluate the clinical outcome of early closure of a protective ileostomy and preoperative stimulation of the efferent limb in a cohort of patients with rectal cancer treated surgically, primarily using the laparoscopic approach., Methods: We performed an observational retrospective cohort study in a prospectively recorded series of patients with rectal cancer who underwent laparoscopic surgery with a protective loop ileostomy between 2017 and 2022. Ileostomy closure was programmed for within 3 months after surgery. All patients underwent stimulation of the efferent limb. Primary outcomes were morbidity and mortality, length of stay (LOS), and re-admission., Results: Between 2017 and 2022, 108 patients underwent resection for rectal cancer and protective ileostomy. The laparoscopic approach was performed in 84.3% of patients (n = 91). Permanent ileostomy was performed in 5 patients (4.6%). Ileostomy closure was thus performed in 95.4% of patients (n = 103). Median time to closure was 74.5 days (range 57-113). In 63.1% (n = 65) of patients, reconstructive surgery was performed within 90 days. Prior to closure, efferent limb stimulation was performed in 77.8% (n = 84) of patients. Global morbidity was 26.2% (n = 27) (85.19%, n = 23 Clavien-Dindo I and 7.41%, n = 2 Clavien-Dindo II). The main causes of morbidity were postoperative ileus (10.7%, n = 11) and rectal bleeding (8.7%, n = 9). Anastomosis leakage occurred in 2 patients. Median hospital stay was 6 days (5-7). Readmission was needed in 6.8% (n = 7) of patients., Conclusion: A previous laparoscopic approach, early closure and stimulation of the efferent limb could be a useful strategy to reduce the morbidity and mortality of temporary ileostomy closure., (Published by Elsevier España, S.L.U.)

Objective: To analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease., Methods: Data from the EDEN (Emergency Department and Elderly Need) cohort were used. This retrospective cohort included all patients aged ≥65 years seen in 52 Spanish EDs during two weeks (from 1-4-2019 to 7-4-2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality., Results: 6054 patients were analyzed. Median age was 80 years (IQR 73-87) and 45.3% women. 993 (16,4%) patients died. NEWS score had better AUC than qSOFA (0.765, 95CI: 0.725-0.806, versus 0.700, 95%CI: 0.653-0.746; P < .001) and GYM (0.716, 95%CI: 0.675-0.758; P = .024), and there was no difference between qSOFA and GYM (P = .345). The highest sensitivity scores for 30-day mortality were GYM ≥ 1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWS ≥ 8 showed high specificity., Conclusion: NEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity., (Copyright © 2024. Published by Elsevier España, S.L.U.)

Background/Objectives : The evaluation of the efficacy of antibacterial treatments in complex oral ecosystems is limited by the inability to differentiate live from dead bacteria using omic techniques. The objective of this study was therefore to assess the ability of the combination of the 16S rRNA Illumina sequencing methodology and the action of propidium monoazide (PMA) to study viable bacterial profiles in oral biofilms after exposure to an antiseptic compound. Methods : Cariogenic supragingival biofilms were developed in an ex vivo model for 96 h, using saliva from healthy volunteers. The biofilms were treated with 0.12% chlorhexidine (CHX) combined with 0.05% cetylpyridinium chloride (CPC), for 60 s, using phosphate buffered saline as a control. After exposure, each biofilm was treated or not with PMA to then extract the bacterial DNA, quantify it by Qubit, quantify the bacterial population using qPCR, and perform the metataxonomic study of the samples using Illumina 16S rRNA sequencing. Results : A significantly lower DNA concentration in the PMA-treated biofilms ( p < 0.05 compared with those not exposed to PMA) was observed. The viable bacterial count obtained by qPCR differed significantly from the total bacterial count in the biofilm samples exposed to the antiseptic ( p < 0.05). The viable microbiome differed significantly from the total bacterial profile of the samples treated with CHX/CPC after exposure to PMA ( p < 0.05 at the α- and β-diversity levels). Conclusions : The combination of Illumina 16S rRNA sequencing and PMA helps solve the inability to evaluate the efficacy of antibacterial treatments in the bacterial profile of complex ecosystems such as oral biofilms.

Background: The success of anti-tumor necrosis factor (TNF) drug strategies in the treatment of inflammatory bowel disease (IBD) is altered by the development of anti-drug antibodies that reduce their efficacy. Studies have shown that the HLA-DQA1⋆05 allele increases the risk of immunogenicity to anti-TNF drugs approximately twofold., Objective: Analyze whether the presence of the HLA-DQA1⋆05 allele is associated with the development of immunogenicity and to evaluate the disease response to anti-TNF drugs (infliximab (IFX) and adalimumab (ADA)), according to the presence of this allele., Design: This is an observational retrospective cohort study, single center, to determine the impact of HLA-DQA1⋆05 on disease activity in patients with IBD at the Hospital Universitario Virgen Macarena., Methods: In total, 200 IBD patients were included: 109 treated with IFX and 91 with ADA. Data were collected using the computerized medical records from the DIRAYA program of the Servicio Andaluz de Salud. Response-defined as improvement-and remission-defined as the disappearance of symptoms and analytical/endoscopic signs-were assessed using activity indices (partial Mayo, Harvey-Bradshaw) in all patients. Anti-TNF drug levels were also determined, as well as the presence or absence of anti-IFX and anti-ADA antibodies. The reporting of this study conforms to the Strengthening the Reporting of Observational Studies in Epidemiology statement., Results: The HLA-DQA1⋆05 haplotype was present in 70 (35%) patients, including 39 (36%) treated with IFX and 31 (34%) with ADA. The risk of withdrawal, intensification, as well as antibody development, was higher in patients carrying the allele and on treatment with IFX or ADA., Conclusion: In our study, we demonstrated that there is an increased risk of immunogenicity in patients carrying the HLA-DQA1⋆05 genotype, which would support the idea of screening for this genetic variant before starting anti-TNF therapy, as its prevalence is high in the general population and increases the risk of treatment discontinuation due to loss of response., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

The present study aimed to evaluate whether primed anoestrus mares are suitable recipients for embryos produced by intracytoplasmic sperm injection (ICSI). Anoestrus was confirmed in four mares and daily doses of oestradiol benzoate (6 mg in total) over 5 days were administered; after 3 days of rest, oral altrenogest was administered at 0.088 mg/kg and embryos (1 to 5 embryos per mare; 15 in total) were transferred 3.5 days after progesterone onset. Uterine lavage was conducted 48 h after transfer. The results revealed an 80% embryo recovery rate, and among the retrieved embryos, 67% showed evident intrauterine development. Hence, ICSI-derived embryos can be successfully transferred to primed anoestrus mares, but more studies are required to ensure further embryo development and foaling., (© 2024 The Author(s).

A protocol for conventional in vitro fertilization (IVF) in horses using fresh semen has been described, using a prolonged incubation in FERT-TALP medium (22 h) at 38.2°C in the presence of penicillamine, hypotaurine and epinephrine (PHE). Our work aimed to develop a protocol that maintains quality parameters in frozen-thawed equine spermatozoa incubated for 22 h in the presence of PHE using different media (FERT-TALP and INRA96) and incubation temperatures (30 and 38.2°C). Twelve frozen ejaculates from four stallions were thawed and then incubated in either FERT-TALP or INRA96 with PHE at 30 or 38.2°C for 22 h. Following incubation, total motility (TM), progressive motility (PM), viability and acrosome integrity were evaluated. The results showed that TM was significantly higher (p < .001) at 30°C in both media, while PM was higher for INRA96 at 30°C compared to 38°C (p < .05). Moreover, INRA96 at 30°C exhibited higher sperm viability and acrosome integrity (p < .001) compared to the other experimental groups. These preliminary results suggest that incubating thawed equine spermatozoa at 30°C with PHE in INRA96 successfully maintains motility, viability and acrosome integrity in equine spermatozoa, indicating its potential use for conventional equine IVF., (© 2024 The Authors.

This paper presents information on the morphological, morphometric, and dental sex differences in the dwarf round ray Urotrygon nana. We recorded 12 morphological traits, sex, the distribution pattern of dermal denticles, the number of tooth rows, and the tooth shape of 466 individuals. The disc width of females ranged from 50 to 172 mm and that of males ranged from 53 to 135 mm. A neuronal classification model and a correspondence analysis showed that female disc width was 21.5% broader, and the distance from the rostrum to the anus was 17.7% longer than that of males, whereas males presented 19.5% greater distance between the nostrils, 9.7% greater preorbital snout length, 6.8% greater cloaca to caudal-fin length, 2.7% greater interorbital distance, and 1.1% greater total length than females. The disc of adult males, including the abdominal cavity area, was densely covered with dermal denticles, which were slightly larger than those observed in females. Females presented homodont dentition with molariform teeth and a smooth lozenge-shaped crown with rounded margins. Males exhibited homodonty but with tooth morphology variations in individuals of different sizes (from molariforms to sharper cusp teeth). There were changes in disc shape (from subcircular to oval), distribution and size of dermal denticles (more abundant and larger), and tooth shape (from molariform to monocuspid teeth) during male development, from neonates to adults. U. nana exhibited sexual dimorphism in size, disc shape, number and shape of teeth, and distribution and size of dermal denticles., (© 2024 Fisheries Society of the British Isles.)

The Andean Altiplano, characterized by its extreme climatic conditions and high levels of biodiversity, provides a unique environment for studying ecological and evolutionary adaptations in insect morphology. Butterflies, due their large wing surface compared to body surface, and wide distribution among a geographical area given the flight capabilities provided by their wings, constitute a good biological model to study morphological adaptations following extreme weathers. This study focuses on Phulia nymphula , a butterfly species widely distributed in the Andes, to evaluate wing shape variation across six localities in the Northern Chilean Altiplano. The geometric morphometrics analysis of 77 specimens from six locations from the Chilean Altiplano (Caquena, Sorapata Lake, Chungará, Casiri Macho Lake, Surire Salt Flat, and Visviri) revealed significant differences in wing shape among populations. According to the presented results, variations are likely influenced by local environmental conditions and selective pressures, suggesting specific adaptations to the microhabitats of the Altiplano. The first three principal components represented 60.92% of the total wing shape variation. The detected morphological differences indicate adaptive divergence among populations, reflecting evolutionary responses to the extreme and fragmented conditions of the Altiplano. This study gives insights into the understanding of how high-altitude species can diversify and adapt through morphological variation, providing evidence of ecological and evolutionary processes shaping biodiversity in extreme environments.

Background/objectives: Choline and essential fatty acids (EFA) are vital for fetal brain development, supporting pregnancy, and maintaining hormonal balance. They also promote overall health. The childbearing years present a window of opportunity to increase the intake of these key nutrients and develop healthy dietary habits. The aims of this study were to evaluate the intake of choline and EFA in women of childbearing age (15-49 years old), identify their food sources and determine if supplements containing choline and EFA were available across the Estudio Latinoamericano de Nutrición y Salud (ELANS) countries., Methods: Survey data were collected for the ELANS, including participants from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela ( n = 9218; 15-65 years old). Women of childbearing age were extracted from the largest database ( n = 3704)., Results: In general, choline intake was inadequate in all countries, while EFA intake was normal or above requirements. Chile had the lowest intake of choline, and Colombia had the highest. The results showed that some countries had more inadequate choline intake than others. Consuming a larger quantity of eggs helped reduce choline inadequacy, as did including eggs and fish in the diet. The intake of EFA, including ALA, EPA, and DHA, showed variability. The contributions of EPA and DHA were lower than that of ALA, and the results differed by age group., Conclusions: choline intake is inadequate, and EFA intake is variable among women of childbearing age in the ELANS study. More awareness and education are needed to achieve better intake of these nutrients.

Introduction: Aortic arch complex atheromatosis is a source of cerebral embolism. A percentage of lacunar infarct could be of embolic etiology, especially due to microemboli of the aortic arch., Case Report: We present the case of a 63-year-old hypertensive man suffering from dysarthria-clumsy hand syndrome for a right hemispheric minor ischemic stroke. The patient developed sequential acute thromboembolism of the left lower and right upper limbs. Computed tomography angiography revealed an aortic arch thrombus. Vascular surgery was successfully performed., Conclusion: This case highlights the importance of considering embolic sources in lacunar syndromes, especially at the level of the aortic arch.

Background: The impact of the COVID-19 pandemic on older adults in nursing homes is significant, with high death rates, disrupted care, isolation measures, and inadequate treatment. Social isolation has increased risks of cognitive disorders, anxiety, and depression. While many studies have examined the pandemic's effects on nursing home staff and residents' families, less is known about the health consequences for the residents themselves. This review aims to synthesize literature on the COVID-19 lockdown's impact on the functional, cognitive, and psycho-emotional states of older adults in nursing homes., Methods: A scoping review was conducted following the Joanna Briggs Institute guidelines and the PRISMA extension for Scoping Reviews (PRISMA-ScR). Four databases were searched: CINAHL, PubMed, Web of Science, and PsycINFO. The eligibility criteria included studies on older adults in nursing homes during the COVID-19 pandemic, with data that could be disaggregated for this population and results on the lockdown's impact on physical, cognitive, and psycho-emotional levels., Results: Seventeen articles met the criteria for data extraction The synthesis was categorized into four main areas: functional, cognitive and psycho-emotional status, and isolation measures. Key findings included decreased functional abilities, lower cognitive test scores during the pandemic's first waves, development of psychological symptoms, and increased negative feelings among residents., Conclusions: Highlighting the consequences of confinement for nursing home residents is essential for updating evidence, developing effective strategies, and establishing protocols to mitigate the impact and prevent health issues in future pandemics., (© 2024.

Background: Cancer and its treatments cause symptoms such as pain, fatigue, and emotional distress, which affect the quality of life of patients at different stages of cancer. Virtual reality (VR) has emerged as a promising alternative for addressing these symptoms by immersing patients in a virtual environment that isolates them from reality., Objective: To describe the existing evidence on the use of VR to improve pain, fatigue, and emotional distress in people with cancer at different stages of the cancer trajectory., Methods: A scoping review was conducted following the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Search was conducted in PubMed and CINAHL until October 2023., Results: Twenty-three primary studies related to the study topic were identified, and the following information was collected: type of VR (immersive vs nonimmersive) used in oncology services, purpose (distraction, training, or relaxation), devices used (head-mounted display, headset, or virtual controller), and the environment simulated (natural environment, skill games, or educational environment). The effects of VR on pain, fatigue, and emotional distress are described, highlighting its ability to mitigate these symptoms in the short term., Conclusions: Virtual reality has been shown to be an effective technique for reducing pain, fatigue, and emotional distress in people with cancer in the short term., Implications for Practice: Nurses can use VR as a complementary tool to promote virtual environments that improve the care for and therefore the quality of life of people with cancer., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: The aim of this paper is to develop a preliminary theory that explores in depth into understanding the experiences of women who have suffered a spontaneous perinatal loss during any trimester of their pregnancy regarding their emotional response to this loss., Design: A grounded theory approach was used, and 25 in-depth interviews were conducted with Spanish women who suffered a spontaneous perinatal loss., Methods: Theoretical sampling and constant comparative analysis were used to reach theoretical saturation. EQUATOR guidelines were followed, using the COREQ checklist., Results: The "Perinatal loss, a devastating cyclone," a situation-specific nursing theory, explains the process that a woman experiences when she loses her baby at any stage of pregnancy, drawing an analogy with tropical cyclones as natural disasters that destroy everything in their path. This situation-specific theory includes three dimensions, explaining the phases identified in the perinatal loss process (phase prior to impact [before the perinatal loss], impact phase [diagnostic moment], emergency phase [hospital care], relief or honeymoon phase [return home], disillusionment or stock-taking phase [after the first postloss days at home], reconstruction and recovery phase [grief construction process] and consequences [with an eye to the future]). Three intervention areas were described around the perinatal loss process: "rescue area" (partner, grandparents, and siblings of the deceased baby), "relief area" (healthcare professionals), and "base camp" (society)., Conclusion: The situation-specific nursing theory "Perinatal loss, a devastating cyclone" is the final product of a grounded theory study that provided an in-depth analysis of women's experiences when they suffer a spontaneous perinatal loss at any point in their pregnancy., Clinical Relevance: The situation-specific theory "Perinatal loss, a devastating cyclone" with the seven identified phases and the three areas of intervention could be used as a framework for healthcare professionals in their clinical practice as a guide to support women in this disfranchised grief., (© 2024 The Author(s).

Losing a newborn is for many mothers a painful end in which death occurs when life is expected, which makes them live a time of loneliness, personal doubt and feeling of failure. After carrying out a previous qualitative study analyzing the experiences of 25 women who suffered a spontaneous perinatal loss at any time during pregnancy and a systematic review of the factors that affect the emotional response after perinatal losses, a nursing care proposal is presented based on Watson's Theory of Transpersonal Human Care to respond to the needs of women who experience this loss process. This care plan proposal is intended to achieve individualized care for women who suffer perinatal losses adapted to their needs, not only physical but also emotional., (Copyright © 2024 The Author(s).

When assessing gait analysis outcomes for clinical use, it is indispensable to use an accurate system ensuring a minimal measurement error. Inertial Measurement Units (IMUs) are a versatile motion capture system to evaluate gait kinematics during out-of-lab activities and technology-assisted rehabilitation therapies. However, IMUs are susceptible to distortions, offset and drifting. Therefore, it is important to have a validated instrumentation and recording protocol to ensure the reliability of the measurements, to differentiate therapy effects from system-induced errors. A protocol was carried out to validate the accuracy of gait kinematic assessment with IMUs based on the similarity of the waveform of concurrent signals captured by this system and by a photogrammetry reference system. A gait database of 32 healthy subjects was registered synchronously with both devices. The validation process involved two steps: 1) a preliminary similarity assessment using the Pearson correlation coefficient, and 2) a similarity assessment in terms of correlation, displacement and gain by estimating the offset between signals, the difference between the registered range of motion (∆ROM), the root mean square error (RMSE) and the interprotocol coefficient of multiple correlation (CMC P ). Besides, the CMC P was recomputed after removing the offset between signals (CMC Poff ). The correlation was strong (r > 0.75) for both limbs for hip flexion/extension, hip adduction/abduction, knee flexion/extension and ankle dorsal/plantar flexion. These joint movements were studied in the second part of the analysis. The ∆ROM values obtained were smaller than 6°, being negligible relative to the minimally clinically important difference (MCID) estimated for unaffected limbs, and the RMSE values were under 10°. The offset for hips and ankles in the sagittal plane reached -9° and -8°, respectively, whereas hips adduction/abduction and knees flexion/extension were around 1°. According to the CMC P , the kinematic pattern of hip flexion/extension (CMC P > 0.90) and adduction/abduction (CMC P > 0.75), knee flexion/extension (CMC P > 0.95) and ankle dorsi/plantar flexion (CMC P > 0.90) were equivalent when captured by each system synchronously. However, after offset correction, only hip flexion/extension (CMC Poff = 1), hip adduction/abduction (CMC Poff > 0.85) and knee flexion/extension (CMC Poff > 0.95) satisfied the conditions to be considered similar., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Blanco-Coloma, García-González, Sinovas-Alonso, Torio-Álvarez, Martos-Hernández, González-Expósito, Gil-Agudo and Herrera-Valenzuela.)

To maintain economic profitability and stabilize fuel prices, refineries actively explore alternatives for efficiently processing (extra) heavy crude oils. These oils are challenging to process due to their complex composition, which includes significant quantities of asphaltenes, resins, and sulfur and nitrogen heteroatoms. A critical initial step in upgrading these oils is the hydrogenation of polyaromatic compounds, requiring substantial hydrogen sources. Methane from natural gas streams is known to act as an effective hydrogen donor. This study investigates the use of a heteropolyacid (HPA) catalyst modified with nickel and methane to enhance the quality of heavy crude oil with an initial 8.0°API (at 15.5 °C) and 2200 cSt viscosity (at 37.5 °C). After treatment in a batch reactor at 380 °C and 4.4 MPa for 2 h, the oil properties markedly improved: API gravity increased from 8.0 to 16.0 (at 15.5 °C), and kinematic viscosity reduced from 2200 to 125 cSt (at 37.5 °C). Additionally, there was a significant decrease in asphaltenes (from 38.7 to 16.4% by weight), sulfur (from 5.9 to 4.0% by weight), and nitrogen (from 971 to 695 ppm). This was accompanied by an increase in the volume of light distillates from 1.3 to 4.9%, and middle distillates from 8.8 to 21.0%. These results suggest that nickel-modified HPA catalysts, combined with methane as a hydrogen donor, are a promising option for upgrading heavy crude oils., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

Intramuscular fat (IMF) content is important for meat production and human health, where the host genetics and its microbiome greatly contribute to its variation. The aim of this study is to describe the consequences of the genetic modification of IMF by selecting the taxonomic composition of the microbiome, using rabbits from the 10th generation of a divergent selection experiment for IMF (high (H) and low (L) lines differ by 3.8 standard deviations). The selection altered the composition of the gut microbiota. Correlated responses were better distinguished at the genus level (51 genera) than at the phylum level (10 phyla). The H-line was enriched in Hungateiclostridium , Limosilactobacillus , Legionella , Lysinibacillus , Phorphyromonas , Methanosphaera , Desulfovibrio , and Akkermansia , while the L-line was enriched in Escherichia , Methanobrevibacter , Fonticella , Candidatus Amulumruptor , Methanobrevibacter , Exiguobacterium , Flintibacter , and Coprococcus , among other genera with smaller line differences. A microbial biomarker generated from the abundance of four of these genera classified the lines with 78% accuracy in a logit regression. Our results demonstrate different gut microbiome compositions in hosts with divergent IMF genotypes. Furthermore, we provide a microbial biomarker to be used as an indicator of hosts genetically predisposed to accumulate muscle lipids, which opens up the opportunity for research to develop probiotics or microbiome-based breeding strategies targeting IMF.

This study presents evidence that lead metavanadate, PbV 2 O 6 , is a material with zero-linear compressibility, which maintains its crystal size in one crystallographic direction even under external pressures of up to 20 GPa. The orthorhombic polymorph of PbV 2 O 6 (space group Pnma ) was studied up to 20 GPa using synchrotron powder X-ray diffraction, Raman spectroscopy, and density-functional theory simulations to investigate its structural and vibrational evolution under compression. Up to this pressure we find no evidence of any structural phase transitions by any diagnostic technique, however, a progressive transformation of the coordination polyhedron of vanadium atoms is revealed which results in the zero-linear compressibility. High-pressure Raman experiments enabled the identification and symmetry assignation of all 54 zone-centre Raman-active modes as well as the calculation of their respective pressure coefficients. Three independent high-pressure powder X-ray diffraction experiments were performed using different pressure-transmitting media (Ne, 4 : 1 methanol-ethanol mixture, and silicone oil). The results show a high anisotropic behaviour in the linear compressibility of the crystallographic axes. The PbV 2 O 6 bulk modulus of 86.1(9) GPa was determined using a third-order Birch-Murnaghan equation of state. The experimental results are supported by ab initio density-functional theory calculations, which provide vibrational patterns, unit-cell parameters, and atomic positions. These calculations also reveal that, unlike MgV 2 O 6 and ZnV 2 O 6 , the band gap of PbV 2 O 6 closes with pressure at a rate of -54 meV GPa -1 due to the contribution of the Pb 6s orbital to the top of the valence band.

Purpose: To develop a nursing diagnosis proposal derived from the concept of "disuse syndrome" based on an integrative review., Methods: The conceptual derivation technique, proposed by Walker and Avant, was used in the following phases: an integrative review of the literature was carried out, applying the parameters of Whitermore and Knalf, where 43 articles were selected that covered the existence of the concept in the nursing discipline and other health sciences, the concepts were subsequently analyzed, and the new concept was redefined following the middle-range theory of causality and validation of nursing diagnoses proposed by Oliveira-Lopes et al., Findings: The proposal of the new nursing diagnosis was developed, including the following elements: diagnostic label adult disuse syndrome, the corresponding definition, 25 defining characteristics, eight related factors, eight risk populations, and 14 associated problems., Conclusions: The concept of the proposed new diagnosis describes adult disuse syndrome as a phenomenon that transcends the physiological component and should be viewed from a multidimensional view, expressing a clinical judgment related to a series of nursing diagnoses that appear together., Implications for Nursing Practice: The results of this study will help nursing professionals to identify the phenomenon of adult disuse syndrome in any setting and in turn guide optimal care interventions that decrease the consequences of adult disuse syndrome., (© 2023 NANDA International, Inc.)

Background: Currently, for in vitro embryo production in live mares, immature oocytes are retrieved by transvaginal follicular aspiration or ovum pick up (OPU). Occasionally, ovarian abscesses have been described after OPU, but no current consensus exists on how to treat this condition., Objectives: To describe diagnosis and successful treatment of ovarian abscesses in two mares subjected to OPU., Study Design: Case report., Methods: Case records were reviewed and summarised., Results: In the first case, a pony mare showed tachypnoea, tachycardia, high temperature, leukocytosis, left hindlimb lameness and slight increase in concentration of serum amyloid A. Ultrasonography revealed an increase in the size of the left ovary and two well defined structures suggestive of ovarian abscess. A left ovariectomy by standing laparoscopy was the treatment of choice: the diagnosis was confirmed, and bacterial culture produced heavy growth of Streptococcus equi Zooepidemicus. In the second mare, an abnormal structure was observed in the left ovary in a routine transrectal ultrasonographic exam in the absence of any clinical signs or abnormal blood parameters. A medical approach was chosen and a sample of the purulent material was aspirated with a transvaginal ultrasound-guided approach. The sample yielded a heavy growth of Streptococcus equi Zooepidemicus after culture. Treatment was initiated with rifampicin and trimethoprim-sulfadiazine based on the antibiogram results and the abscess completely resolved after 40 days., Main Limitations: Limited to two cases., Conclusions: Ovarian abscesses in mares can be successfully treated both surgically and medically., (© 2023 The Authors.

Background: In vitro embryo production is a highly demanded reproductive technology in horses, which requires the recovery (in vivo or post-mortem) and in vitro maturation (IVM) of oocytes. Oocytes subjected to IVM exhibit poor developmental competence compared to their in vivo counterparts, being this related to a suboptimal composition of commercial maturation media. The objective of this work was to study the effect of different concentrations of secretome obtained from equine preovulatory follicular fluid (FF) on cumulus-oocyte complexes (COCs) during IVM. COCs retrieved in vivo by ovum pick up (OPU) or post-mortem from a slaughterhouse (SLA) were subjected to IVM in the presence or absence of secretome (Control: 0 µg/ml, S20: 20 µg/ml or S40: 40 µg/ml). After IVM, the metabolome of the medium used for oocyte maturation prior (Pre-IVM) and after IVM (Post-IVM), COCs mRNA expression, and oocyte meiotic competence were analysed., Results: IVM leads to lactic acid production and an acetic acid consumption in COCs obtained from OPU and SLA. However, glucose consumption after IVM was higher in COCs from OPU when S40 was added (Control Pre-IVM vs. S40 Post-IVM: 117.24 ± 7.72 vs. 82.69 ± 4.24; Mean µM ± SEM; p < 0.05), while this was not observed in COCs from SLA. Likewise, secretome enhanced uptake of threonine (Control Pre-IVM vs. S20 Post-IVM vs. S40 Post-IVM: 4.93 ± 0.33 vs. 3.04 ± 0.25 vs. 2.84 ± 0.27; Mean µM ± SEM; p < 0.05) in COCs recovered by OPU. Regarding the relative mRNA expression of candidate genes related to metabolism, Lactate dehydrogenase A (LDHA) expression was significantly downregulated when secretome was added during IVM at 20-40 µg/ml in OPU-derived COCs (Control vs. S20 vs. S40: 1.77 ± 0.14 vs. 1 ± 0.25 vs. 1.23 ± 0.14; fold change ± SEM; p < 0.05), but not in SLA COCs., Conclusions: The addition of secretome during in vitro maturation (IVM) affects the gene expression of LDHA, glucose metabolism, and amino acid turnover in equine cumulus-oocyte complexes (COCs), with diverging outcomes observed between COCs retrieved using ovum pick up (OPU) and slaughterhouse-derived COCs (SLA)., (© 2024.

Universal health coverage has been proposed as a strategy to improve health in low- and middle-income countries, but this depends on a good provision of health services. Under-5 mortality (U5M) reflects the quality of health services, and its reduction has been a milestone in modern society, reducing global mortality rates by more than two-thirds between 1990 and 2020. However, despite these impressive achievements, they are still insufficient, and most deaths in children under 5 can be prevented with the provision of timely and high-quality health services. The aim of this paper is to conduct a literature review on amenable (treatable) mortality in children under 5. This indicator is based on the concept that deaths from certain causes should not occur in the presence of timely and effective medical care. A systematic and exhaustive review of available literature on amenable mortality in children under 5 was conducted using MEDLINE/PubMed, Cochrane CENTRAL, OVID medline, Scielo, Epistemonikos, ScienceDirect, and Google Scholar in both English and Spanish. Both primary sources, such as scientific articles, and secondary sources, such as bibliographic indices, websites, and databases, were used. Results: The main cause of amenable mortality in children under 5 was respiratory disease, and the highest proportion of deaths occurred in the perinatal period. Approximately 65% of avoidable deaths in children under 5 were due to amenable mortality, that is, due to insufficient quality in the provision of health services. Most deaths in all countries and around the world are preventable, primarily through effective and timely access to healthcare (amenable mortality) and the management of public health programs focused on mothers and children (preventable mortality).

The metagenomic surveillance of antimicrobial resistance in wastewater has been suggested as a methodological tool to characterize the distribution, status, and trends of antibiotic-resistant bacteria. In this study, a cross-sectional collection of samples of hospital-associated raw and treated wastewater were obtained from February to March 2020. Shotgun metagenomic sequencing and bioinformatic analysis were performed to characterize bacterial abundance and antimicrobial resistance gene analysis. The main bacterial phyla found in all the samples were as follows: Proteobacteria , Bacteroides , Firmicutes , and Actinobacteria . At the species level, ESKAPEE bacteria such as E. coli relative abundance decreased between raw and treated wastewater, but S. aureus , A. baumannii , and P. aeruginosa increased, as did the persistence of K. pneumoniae in both raw and treated wastewater. A total of 172 different ARGs were detected; bla OXA , bla VEB , bla KPC , bla GES , mphE , mef , erm , msrE , AAC(6') , ant(3″) , aadS , lnu , PBP-2 , dfrA , vanA-G , tet , and sul were found at the highest abundance and persistence. This study demonstrates the ability of ESKAPEE bacteria to survive tertiary treatment processes of hospital wastewater, as well as the persistence of clinically important antimicrobial resistance genes that are spreading in the environment.
