ABSTRACT
Uveitis is a group of inflammatory ocular pathologies. Endotoxin-Induced Uveitis (EIU) model represent a well-known model induced by administration of Lipopolysaccharide (LPS). The aim is to characterize two models of EIU through two routes of administration with novel noninvasive imaging techniques. 29 rats underwent Intraocular Pressure (IOP) measurements, Optical Coherence Tomography (OCT), proteomic analysis, and Positron Emission Tomography and Computed Tomography (PET/CT). Groups included healthy controls (C), BSS administered controls (Ci), systemically induced EIU with LPS (LPSs), and intravitreally induced EIU with LPS (LPSi) for IOP, OCT, and proteomic studies. For 18F-FDG PET/CT study, animals were divided into FDG-C, FDG-LPSs and FDG-LPSi groups and scanned using a preclinical PET/CT system. LPSi animals exhibited higher IOP post-induction compared to C and LPSs groups. LPSi showed increased cellular infiltrate, fibrotic membranes, and iris inflammation. Proinflammatory proteins were more expressed in EIU models, especially LPSi. PET/CT indicated higher eye uptake in induced models compared to FDG-C. FDG-LPSi showed higher eye uptake than FDG-LPSs but systemic uptake was higher in FDG-LPSs due to generalized inflammation. OCT is valuable for anterior segment assessment in experimental models. 18F-FDG PET/CT shows promise as a noninvasive biomarker for ocular inflammatory diseases. Intravitreal induction leads to higher ocular inflammation. These findings offer insights for future inflammatory disease research and drug studies.
ABSTRACT
BACKGROUND: The present study analyses the effect of a Movement-Based Intervention to improve Actual and Perceived Motor Competence in children with probable Developmental Coordination Disorder aged four and six years. METHODS AND PROCEDURES: A longitudinal pre-experimental study was designed with measurements conducted at pre-test, post-test and follow-up (after 5 months without intervention). The group, composed of children with probable Developmental Coordination Disorder or low motor competence, consisted of 57 participants, and the duration of a Movement-Based Intervention was 27 sessions allocated in nine weeks. OUTCOMES AND RESULTS: Actual Motor Competence was evaluated with the Movement Assessment Battery for School children and Perceived Motor Competence with Pictorial Scale of Perceived Motor Skill Competence for Children. The results showed significant improvements in both study variables (Actual Motor Competence and Perceived Motor Competence), both at post-test and follow-up, five months after the end of the intervention. In conclusion, a Movement-based Intervention is effective in improving Actual and Perceived Motor Competence in the participants of this research, children with low motor competence or probable Developmental Coordination Disorder. WHAT THIS PAPER ADDS: Considering the improvements observed after the program in Spanish sample, it seems that the usual practice in Early Childhood Education in our context may not be sufficient, i.e., it may not provide children with the necessary support (number of lesson and time) and appropriate learning contexts to promote the development of their motor skills. Considering the results, this study suggests that using an Movement-Based Intervention with an appropriate pedagogical approach, and offering different learning opportunities to children according to their needs, could positively influence their Actual and Perceived Motor Competence, and could motivate them towards future practice.

PURPOSE OF REVIEW: This systematic review aimed to examine existing evidence related to associations between eating behaviours and dietary intake in children and adolescents, with a focus on the Children Eating Behaviour Questionnaire (CEBQ) and the Dutch Eating Behaviour Questionnaire (DEBQ) as assessment tools. RECENT FINDING: We conducted a systematic review following PRISMA guidelines. We included observational and interventional studies published in English, Spanish, or Portuguese, that evaluated the association between eating behaviours and food and beverage intake. Thirteen studies from nine countries met the inclusion criteria, with sample sizes ranging from 62 to 4,914 individuals aged 2 to 16 years-old. Ten studies used the CEBQ, and three used the DEBQ. Our retrieved studies showed that children and adolescents engaging in food approach behaviours tend to consume foods rich in sugar and fats. However, we observed a higher consumption of fruits and vegetables. On the other hand, children and adolescents with lower engagement to food avoidant behaviours, generally exhibited a lower overall food consumption, except for snacks, which they consumed at a higher rate. This systematic review suggests that eating behaviours play an important role in shaping dietary intake. Nevertheless, due to the heterogeneity related to eating behaviours and diet intake, it highlights the need for further research to understand these complex relationships to develop effective interventions for promoting healthy eating habits in children and adolescents.

Work-related musculoskeletal disorder of upper extremity multi-task assessment methods (Revised Strain Index [RSI], Distal Upper Extremity Tool [DUET]) and manual handling multi-task assessment methods (Revised NIOSH Lifting Equation [RNLE], Lifting Fatigue Failure Tool [LiFFT]) were compared. RSI and DUET showed a strong correlation (rs = 0.933, p < 0.001) where increasing risk factor exposure resulted in increasing outputs for both methods. RSI and DUET demonstrated fair agreement (κ = 0.299) in how the two methods classified outputs into risk categories (high, moderate or low) when assessing the same tasks. The RNLE and LiFFT showed a strong correlation (rs = 0.903, p = 0.001) where increasing risk factor exposure resulted in increasing outputs, and moderate agreement (κ = 0.574) in classifying the outputs into risk categories (high, moderate or low) when assessing the same tasks. The multi-task assessment methods provide consistent output magnitude rankings in terms of increasing exposure, however some differences exist between how different methods classify the outputs into risk categories.

Established risk factors for osteoarthritis (OA) include obesity, joint injury, age, race, and genetics. However, the relationship between cigarette smoking and OA has yet to be established. In the present study, we have employed the use of cigarette smoke extract (CSE), the water-soluble vapor phase of cigarette smoke, with porcine cartilage explants to investigate the effects of cigarette smoking on cartilage catabolism at the tissue level. Articular cartilage explants were first exposed to 2.5%, 5%, and 10% CSE to assess its effects on cartilage homeostasis. Following, the effects of CSE on OA-like inflammation was observed by culturing explants with a combined treatment of IL-1ß and TNF-α and 10% CSE (CSE + OA). Cartilage explants were assessed for changes in viability, biochemical composition, extracellular matrix (ECM) integrity, and equilibrium mechanical properties (aggregate modulus and hydraulic permeability). CSE alone leads to both a time- and dose-dependent decrease in chondrocyte viability but does not significantly affect sGAG content, percent sGAG loss, or the ECM integrity of cartilage explants. When IL-1ß and TNF-α were combined with 10% CSE, this led to a synergistic effect with more significant losses in viability, significantly more sGAG loss, and significantly higher production of ROS than OA-like inflammation only. Cartilage explant equilibrium mechanical properties were unaffected. Within the timeframe of this study, CSE alone does not cause OA but when combined with OA-like inflammation leads to worsened articular cartilage degeneration as measured by chondrocyte viability, sGAG loss, proteoglycan staining, and ROS production.

Suicide is a significant public health concern, with one million lives lost to it every year. Suicidal ideation and attempts are markers of high risk. The COVID-19 pandemic has had a negative psychological impact on the population. This study aims to describe and analyze the clinical and sociodemographic characteristics of patients who have received medical attention for self-harm attempts in a hospital emergency department, comparing the period before and after the COVID-19 pandemic. This is a descriptive, retrospective study that collected data from medical records of patients who received care for self-harm attempts in the emergency department. The data included cases from 1 January 2018 to 31 December 2022. In total, 529 cases of self-harm attempts were identified, of which 62.8% were female. The number of post-pandemic self-harm attempts significantly increased compared to the period before the pandemic. The most used method for self-harm was medication ingestion. This study revealed that over one-third of the participants had previously attempted suicide. Most self-harm attempts were made by women in the 10-20 or 41-50 age groups, with a history of psychiatric illness and multiple medications. The study results also highlighted an increase in self-harm attempts during the COVID-19 pandemic.
ABSTRACT
One in three hospitalized children have disease-related malnutrition (DRM) upon admission to hospital, and all children are at risk for further nutritional deterioration during hospital stay; however, systematic approaches to detect DRM in Canada are lacking. To standardise and improve hospital care, the multidisciplinary pediatric working group of the Canadian Malnutrition Taskforce aimed to develop a pediatric, inpatient nutritional care pathway based on available evidence, feasibility of resources, and expert consensus. The working group (n = 13) undertook a total of four meetings: an in-person meeting to draft the pathway based on existing literature and modelled after the Integrated Nutrition Pathway for Acute Care (INPAC) in adults, followed by three online surveys and three rounds of online Delphi consensus meetings to achieve agreement on the draft pathway. In the first Delphi survey, 32 questions were asked, whereas in the second and third rounds 27 and 8 questions were asked, respectively. Consensus was defined as any question/issue in which at least 80% agreed. The modified Delphi process allowed the development of an evidence-informed, consensus-based pathway for inpatients, the Pediatric Integrated Nutrition Pathway for Acute Care (P-INPAC). It includes screening <24 h of admission, assessment with use of Subjective Global Nutritional Assessment (SGNA) <48 h of admission, as well as prevention, and treatment of DRM divided into standard, advanced, and specialized nutrition care plans. Research is necessary to explore feasibility of implementation and evaluate the effectiveness by integrating P-INPAC into clinical practice.

Commercial swine producers are responsible for implementing changes in their production systems to ensure animal welfare. The objective of this study is to evaluate the levels of animal welfare on rearing and fattening farms certified in good animal husbandry practices using the Welfare Quality® protocol. Eighty-one certified commercial farms (n = 2,150 pigs), distributed in six geographical areas of Colombia, were evaluatedby six trained veterinarians. . A multilevel analysis was performed to identify variables associated with the animal welfare/farm rating and to identify behavioral variables. Farms evaluated had an enhanced (n = 68, 83.9%), followed by excellent (n = 7, 8.7%) and acceptable (n = 6, 7.4%) level of animal welfare. Variables significantly associated with the overall protocol rating (R2 = 0.37) were temperature comfort (OR: 1.05, p = 0.008), absence of disease (OR: 1.06, p = 0.02) and absence of pain (OR: 1.06, p = 0.0001). Significant differences in behavioral measures were observed across farms (P < 0.05). The high animal welfare scores of certified farms suggest changes in producers' understanding and attitudes towards production and animal welfare.

PURPOSE: Neonates with intestinal failure (IF) are at risk for infection due to central venous access, and intestinal surgery. Infection can cause systemic inflammation and sepsis, potentially affecting growth. The purpose of this study was to identify risk factors for, and the potential impact of infection to help with preventative strategies. METHODS: A retrospective review of infants with IF, at a single centre from 2018 to 2022 was conducted. Clinical characteristics, intestinal pathology, nutritional intake, and growth were compared among infants with bloodstream infection (BSI), other infection (OI) (urinary, respiratory, or wound), or no infection (NI) within 2 months of diagnosis. Mann-Whitney and Kruskal-Wallis tests were used for comparisons with p-values <0.05 considered significant. RESULTS: Eighty-six infants were included, with gastroschisis (41%) and necrotizing enterocolitis (26%) the most common diagnoses. Fifty-nine % of infants developed infection (22% BSI and 37% OI). Those with BSI or OI had a lower gestational age and birthweight, and were more likely to have a stoma. All infants with complex gastroschisis developed infection compared to 38% of infants with simple gastroschisis. Median daily weight gain was suboptimal across all groups and did not differ over 6 weeks following infection. CONCLUSION: Most infants with IF develop infection shortly after diagnosis. Risk factors include prematurity, complex gastroschisis, and the presence of a stoma. Growth was suboptimal but did not differ among infants with or without infection. TYPE OF STUDY: Retrospective Review. LEVEL OF EVIDENCE: Level III Retrospective Comparative Study.

Flowers are the complex and highly diverse reproductive structures of angiosperms. Because of their role in sexual reproduction, the evolution of flowers is tightly linked to angiosperm speciation and diversification. Accordingly, the quantification of floral morphological diversity (disparity) among angiosperm subgroups and through time may give important insights into the evolutionary history of angiosperms as a whole. Based on a comprehensive dataset focusing on 30 characters describing floral structure across angiosperms, we used 1201 extant and 121 fossil flowers to measure floral disparity and explore patterns of floral evolution through time and across lineages. We found that angiosperms reached their highest floral disparity in the Early Cretaceous. However, decreasing disparity toward the present likely has not precluded the innovation of other complex traits at other morphological levels, which likely played a key role in the outstanding angiosperm species richness. Angiosperms occupy specific regions of the theoretical morphospace, indicating that only a portion of the possible floral trait combinations is observed in nature. The ANA grade, the magnoliids, and the early-eudicot grade occupy large areas of the morphospace (higher disparity), whereas nested groups occupy narrower regions (lower disparity).

El presente trabajo describe la percepción de una maestra-tutora sobre la Competencia Motriz y Relaciones Sociales en escolares de Educación Infantil. Este estudio tuvo un triple objetivo, por un lado, conocer si la maestra-tutora, participante, era capaz de identificar a los escolares con dificultades motrices y sociales. Por otro lado, analizar el impacto de un Programa de Refuerzo Motriz en la Competencia Motriz y en las Relaciones Sociales en estos escolares. Por último, conocer si la maestra-tutora percibe el efecto del programa. En el estudio participó la maestra-tutora y 6 escolares con dificultades motrices, con una edad media de 5.60 años (DT ± 0.53). Se diseñó un estudio pre-experimental mixto que combinó un enfoque cuantitativo para las medidas Pre-Test y Post-Test y un enfoque cualitativo para observar el comportamiento de los participantes. Se evaluó la Competencia Motriz de manera objetiva, mediante la Batería de evaluación (Mabc-2) y se realizó un Sociograma para conocer las Relaciones Sociales. Por otro lado, se pasó un cuestionario a la profesora tutora. Los resultados mostraron que la maestra-tutora, en líneas generales, detecta entre el alumnado a aquellos escolares que presentan dificultades motrices o/y sociales de manera muy evidente. Asimismo, los resultados muestran una mejora en los escolares en ambas variables. En conclusión, los docentes de Educación Infantil como uno de los principales agentes de socialización pueden llegar a ser un elemento fundamental para ayudar a que estos superen las dificultades motrices y sociales (AU)
This paper describes a teacher-tutor's perception of Motor Competence and Social Relationships in pre-school children. The aim of this study was threefold: on the one hand, to find out whether the participating teacher-tutor was able to identify schoolchildren with motor and social difficulties. On the other hand, to analyse the impact of a Motor Reinforcement Programme on Motor Competence and Social Relationships in these schoolchildren. Finally, to find out if the teacher-mentor perceives the effect of the programme. The study involved the teacher-tutor and 6 schoolchildren with motor difficulties, with a mean age of 5.60 years (SD ± 0.53). A mixed pre-experimental study was designed combining a quantitative approach for the Pre-Test and Post-Test measures and a qualitative approach to observe the behaviour of the participants. Motor competence was assessed objectively using the Motor Competence Assessment Battery (Mabc-2) (Henderson et al., 2007) and a Sociogram was conducted to assess Social Relationships. On the other hand, a questionnaire was given to the tutor-teacher. The results showed that the tutor-teacher, in general terms, detects among the students those who present motor and/or social difficulties in a very evident way. Likewise, the results show an improvement in the pupils in both variables.In conclusion, early childhood teachers, as one of the main agents of socialisation, can become a fundamental element in helping children to overcome motor and social difficulties (AU)

Introduction: cystic fibrosis (CF) is a genetic, multisystemic disease, characterized by dysfunction of the exocrine secretion glands secondary to the mutation of a transmembrane protein that acts as a chloride channel. Including its research by the National Neonatal Screening System (SNPN) caused a great impact on the morbidity and mortality of this disease, enabling early diagnosis and treatment. Meconium ileus (MI) is the earliest manifestation of the disease, occurring in 10% to 18% of patients. Objective: to describe a form of early presentation of CF with normal neonatal screening results. Clinical case: 18 months. Female, 33 weeks gestational age. Delay in the expulsion of meconium. On the third day of life, meconium ileus with intestinal obstruction, midgut volvulus and intestinal necrosis. Surgical resection is performed. Trypsin immunoreactive (TIR) normal at 7 and 23 days of age. Pancreatitis-associated protein (PAP) is not requested. Chronic malnutrition, severe bronchiolitis at 3 months, viral pneumonia at 7 and 11 months. Admission with a diagnosis of acute community pneumonia with respiratory failure. Sweat test altered on two occasions. Insufficient pancreatic elastase. Staphylococcus aureus and Pseudomonas aeruginosa were isolated in nasal exudate and respiratory secretions. Genetic study: Delta F508 mutation. With the CF diagnosis, a multidisciplinary approach, treatment and referral to a specialized center began. Conclusions: the existence of MI can provide false negatives in the IRR value, making PAP dosage necessary. The prognosis of these patients will depend on early diagnosis and timely therapeutic management at specialized centers.

INTRODUCTION: Patients with respiratory diseases face adverse situations such as symptom management, general condition deterioration, and a hostile perception of the hospital environment, favoring the appearance of anxiety and depression. METHODS: A total of 317 patients hospitalized for a disease of pulmonary origin were analyzed and divided into the following subgroups: infectious, oncological, acute, and chronic diseases. Patients over 18 years of age with preserved cognitive capacity were included in the study. The Hospital Anxiety and Depression Scale (HADS) was applied to them on the second or fourth day of their hospital stay and five days after the first evaluation. Multiple linear regression models were carried out to analyze the association between anxiety and depression measured over two different periods. The models present the statistically significant variables with a 95% confidence level. RESULTS: The patients presented with anxiety in 74.4% of cases, mainly those with acute respiratory diseases (42.4%) and neoplastic diseases (27.5%). A total of 69.5% presented with depression, with symptoms more significant in those with chronic and oncological pulmonary diseases and those with no job. Patients with at least one comorbidity presented with anxiety in 53.9% of cases and depression in 52.1% of cases. Linear regression models were carried out and showed that anxiety was 1.75 and 1.84 times more frequent in patients with chronic diseases compared to those with infectious pathologies in the first and second reviews, respectively. The linear regression model also showed a higher frequency of depressive symptoms in patients with chronic conditions (1.62 times) compared to the group with infectious and contagious pathologies, and prolonged hospital stays were associated with depressive symptoms 1.37 times more than short stays. CONCLUSIONS: Anxiety and depression are frequent disorders in patients with respiratory diseases, negatively affecting the prognosis. Routine mental health screening and multidisciplinary management are essential in this population.
ABSTRACT
The genus Passiflora comprises more than 500 species distributed in tropical and semitropical regions. With a great diversity of species, it is estimated that one-third is found in Colombian territory. Besides the food importance, Passiflora species are important sources of biologically active compounds, such as flavonoids. The most important symbiosis between soil fungi and vascular plants related to plant nutrition and tolerance to stress conditions is mycorrhizae. Passiflora species form arbuscular mycorrhizae, with several species of Glomeromycota. This association has been reported to alter the production of secondary metabolites. Thus, the objective of this study was to determine the relation between flavonoid content, mycorrhization, and soil nutritional content of Passiflora alata, Passiflora quadrangularis, Passiflora maliformis, and Passiflora ligularis in Colombian crops. The extracts were prepared and analyzed using UPLC/PDA-MS, and total flavonoids were quantified with the method of AlCl3. Soil characteristics, including nutritional content and percentage of colonization by arbuscular mycorrhizal fungi, were also determined. All variables were analyzed using Spearman's correlation and principal component analysis. Chromatographic analysis of the extracts allowed us to visualize the different flavonoid compositions of each extract, identifying several C-glycosylflavonoids. In this paper, we report for the first time the presence of luteolin-8-C-rhamnosyl-4'-O-glucoside, apigenin-6-C-arabinosyl-7-O-glucoside, and orientin for P. maliformis. Statistical analysis showed a negative correlation between available phosphorus (ρ = -0.90, p = <0.05) and magnesium (Mg) saturation (ρ = -0.70, p = <0.05) on flavonoid content, whereas the calcium magnesium (Ca/Mg) ratio was positively correlated (ρ = 0.70, p = <0.01). There was a nonsignificant correlation between mycorrhization and flavonoid content (ρ = -0.70, p = >0.1). These results contribute to understanding the relationship between flavonoid-mycorrhization-soil nutritional content on Passiflora spp.
ABSTRACT
BACKGROUND: Cystinosis is a rare genetic disorder characterized by the accumulation of cystine crystals in several tissues and organs causing, among others, severe eye symptoms. The high instability of cysteamine eye drops makes it difficult to develop formulations with an acceptable shelf life to be prepared in hospital pharmacy departments. Previously, a new compounded formulation of cysteamine eye drops in hyaluronic acid (HA) packaged in innovative single-dose systems was developed. METHODS: Long-term stability at -20 °C of this formulation was studied considering the content of cysteamine, pH, osmolality, viscosity, and microbiological analysis. The oxygen permeability of single-dose containers was also studied and an ocular biopermanence study was conducted in healthy volunteers measuring lacrimal stability and volume parameters. RESULTS: Data confirm that cysteamine concentration remained above 90% for 120 days, all parameters remaining within the accepted range for ophthalmic formulations. The permeability of the containers was reduced over time, while ocular biopermanence was maintained despite the freezing process and storage time. CONCLUSIONS: 0.55% cysteamine hydrochloride formulation in HA and packaged in single-dose containers preserved at -20 °C is stable for 120 days protected from light, presenting high potential for its translation into clinical practice when commercial presentations are not available.
ABSTRACT
BACKGROUND: Hispanic people compared to White people with multiple sclerosis (MS) are two times more likely to present with optic neuritis (ON). ON in dissemination in space (DIS) after a single attack is not part of the current McDonald 2017 criteria. OBJECTIVE: To evaluate if adding ON in DIS (ON-modified criteria) improves the performance of the McDonald 2017 criteria in the diagnosis of MS after a single attack of ON. METHODS: Retrospective study of 102 patients of Hispanic background. Cases were reviewed between 2017 and 2021. Clinical ON was reported for 35 cases. ON in DIS was verified for 28 patients via MRI, optical coherence tomography, and/or visual evoked potential. We investigated the performance of the McDonald 2017 criteria and ON-modified criteria and calculated sensitivity, specificity, positive and negative predictive values, and accuracy. RESULTS: The ON-modified criteria significantly improved the performance of the McDonald 2017 criteria (p = 0.003) and identified an additional nine patients. Both sensitivity and accuracy increased from 64% to 74% and 62% to 71%, respectively, while specificity remained unchanged (40% (95% confidence interval (CI): 0.10, 0.70)). CONCLUSION: This study provides evidence that the inclusion of ON in DIS improved the overall performance of the McDonald 2017 criteria among Hispanic people.

Density functional theory would be exact when the exact exchange-correlation (xc) functional would be known, but since it is regretfully not known, dozens of xc functionals have been developed in the past decades, with some of them better suited for describing certain systems and/or properties. For transition metals (TMs), recent systematic studies assessing bulk propertiesâshortest interatomic bond distance, δ, cohesive energy, Ecoh, and bulk modulus, B0âand surface featuresâsurface energy, γ, work function, Ï, and interlayer distances, δijâof 27 TM bulks and 81 TM surfaces, highlighted that generalized gradient approximation (GGA) based xc functionals are, overall, better suited than other types of xc functionals for the TMs bulk and surfaces description, such as Perdew-Burke-Ernzerhof (PBE) or Vega-Viñes (VV). Still, some basic local density approximation xc functionals were not assessed, such as the Hedin-Lundqvist (HL) and Perdew-Zunger (PZ), or GGAs such as the revised Perdew-Burke-Ernzerhof (revPBE) or the Armiento-Mattsson (AM05). Here, we expand the analysis by not only including them but also the recent meta-GGA strongly constrained appropriately normed (SCAN) xc functional, characterized by fulfilling all 17 mathematical conditions an xc must comply, plus the Bayesian error estimation functional (BEEF) xc, a functional parametrized over a large and diverse set of experimental results using machine learning. The present results reveal that none of the xc studied excel neither PBE nor VV, yet AM05 and SCAN performance is quite acceptable, while BEEF xc probably needs more shells of parametrization to reach competitive accuracy levels.
