Validity, reliability and responsiveness of digital visual analogue scales for chronic spontaneous urticaria monitoring: A CRUSE® mobile health study.

BACKGROUND: CRUSE® is an app that allows patients with chronic spontaneous urticaria (CSU) to monitor their daily disease activity through the use of visual analogue scales (VASs). We aimed to determine the concurrent validity, reliability, responsiveness and minimal important difference (MID) of CRUSE® VASs. METHODS: We evaluated the properties of three daily VASs: VAS for how much patients were affected by their CSU ('VAS urticaria'), VAS for the impact of urticaria on work/school productivity ('VAS productivity') and the VAS of EQ-5D. Concurrent validity was assessed by measuring the association between each VAS and the Urticaria Activity Score (UAS). Intra-rater reliability was determined based on the data of users providing multiple daily questionnaires within the same day. Test-retest reliability and responsiveness (ability to change), respectively, were tested in clinically stable and clinically unstable users. MIDs were determined using distribution-based methods. RESULTS: We included 5938 patients (67,380 days). Concurrent validity was high, with VAS urticaria being more strongly associated with the UAS score than the remaining VASs. Intra-rater reliability was also high, with intraclass correlation coefficients (ICC) being above 0.950 for all VASs. Moderate-high test-retest reliability and responsiveness were observed, with reliability ICC being highest for VAS EQ-5D and responsiveness being highest for VAS urticaria. The MID for VAS urticaria was 17 (out of 100) units, compared to 15 units for VAS productivity and 11 units for VAS EQ-5D. CONCLUSION: Daily VASs for CSU available in the CRUSE® app display high concurrent validity and intra-rater reliability and moderate-high test-retest reliability and responsiveness.

REAL life study of subcutaneous SEMaglutide in patients with type 2 diabetes in SPain: Ambispective, multicenter clinical study. Results in the GLP1-experienced cohort.

OBJECTIVE: To evaluate the efficacy of switching to once-weekly subcutaneous semaglutide in patients with type 2 diabetes mellitus (T2DM) who were previously treated with other glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in a real-world setting in Spain. METHODS: The REAL Life study of SEMaglutide in Patients with Type 2 diabetes in Spain (REALSEM-SP) was conducted in four endocrinology departments in Madrid, Spain. Adult patients with T2DM who were prescribed once-weekly (OW) subcutaneous semaglutide and had been previously treated with other GLP-1 RAs were included. Baseline characteristics, including demographic, anthropometric, and laboratory variables, were recorded at baseline and at 6 ± 3 and 12 ± 3 months of follow-up. The primary outcome was the change in HbA1c at 12 ± 3 months of follow-up, with secondary outcomes including changes in weight, BMI, and other glycemic parameters. RESULTS: A total of 267 patients were included in the analysis, with a mean age of 61.6 years and a mean T2DM duration of 11.3 years. The majority of patients had grade 1 or 2 obesity at baseline. Switching to OW-semaglutide was associated with a significant reduction in HbA1c from baseline to 13 months (-0.35 % ± 0.81). Patients who reached the 1.0 mg OW-dose showed a significant reduction in HbA1c compared to those on the ≤0.5 mg OW-dose. Significant reductions in weight, BMI, and fasting plasma glucose were also observed. Adverse events were mostly gastrointestinal and led to treatment withdrawal in few cases. CONCLUSION: Switching to OW-subcutaneous semaglutide in patients with T2DM previously treated with other GLP-1 RAs was associated to improvements in glycemic control and weight management in a real-world setting in Spain. These findings support the use of OW-semaglutide as an effective option for patients with T2DM who require additional glycemic control and weight management.

Thyroid Hormone Upregulates Cav1.2 Channels in Cardiac Cells via the Downregulation of the Channels' ß4 Subunit.

Thyroid hormone binds to specific nuclear receptors, regulating the expression of target genes, with major effects on cardiac function. Triiodothyronine (T3) increases the expression of key proteins related to calcium homeostasis, such as the sarcoplasmic reticulum calcium ATPase pump, but the detailed mechanism of gene regulation by T3 in cardiac voltage-gated calcium (Cav1.2) channels remains incompletely explored. Furthermore, the effects of T3 on Cav1.2 auxiliary subunits have not been investigated. We conducted quantitative reverse transcriptase polymerase chain reaction, Western blot, and immunofluorescence experiments in H9c2 cells derived from rat ventricular tissue, examining the effects of T3 on the expression of α1c, the principal subunit of Cav1.2 channels, and Cavß4, an auxiliary Cav1.2 subunit that regulates gene expression. The translocation of phosphorylated cyclic adenosine monophosphate response element-binding protein (pCREB) by T3 was also examined. We found that T3 has opposite effects on these channel proteins, upregulating α1c and downregulating Cavß4, and that it increases the nuclear translocation of pCREB while decreasing the translocation of Cavß4. Finally, we found that overexpression of Cavß4 represses the mRNA expression of α1c, suggesting that T3 upregulates the expression of the α1c subunit in response to a decrease in Cavß4 subunit expression.

A cross-sectional assessment of the influence of information sources about substance use in adolescents' tobacco prevalence.

Background: Tobacco consumption is a relevant public health problem, with adolescence being a common period of initiation. One factor that has rarely been investigated is the information available to adolescents regarding the consequences of substance use. Therefore, the primary objective of this study was to assess the correlation between teenagers' self-reported information level about substance consumption and its sources and smoking prevalence. The study differentiates between sources monitored by state or supranational organizations (schools, parents, and mass media) and those that are not (peers, siblings, and the Internet). Three modes of tobacco consumption were examined: cigarette, e-cigarette, and hookah. Methods: This study used a survey conducted in 2023 with teenagers residing in Tarragona (Spain). The survey received 1307 responses from a target demographic comprising approximately 8000 individuals. Hierarchical ordered logistic regression was employed to evaluate the significance of the variables pertaining to each modality of tobacco consumption. The assessed variables encompassed the perceived level of information concerning substance use and the quantity of monitored and unmonitored resources that provide that information. These variables were controlled for four individual and four environmental factors. Results: Logistic regressions indicated that although the extent of information regarding substance consumption consequences does not correlate with smoking in any form, the amount of monitored and unmonitored information resources was significantly associated with all consumption modalities. Information derived from monitored sources consistently exerts a protective effect. In the case of cigarette consumption, the 95 % confidence interval of the odds ratio (95%CI) was 0.43-0.91; for e-cigarrette, 95%CI = 0.45-0.86, and for hookah usage 95%CI = 0.42-0.86. The use of unmonitored resources appears to encourage consumption. In the case of cigarette, 95%CI = 1.08-2.34; for e-cigarette, 95%CI = 1.39-2.69; and for hookah use 95%CI = 1.39-2.68. Conclusions: The results in this paper have significant implications for health literacy dissemination, underscoring the need for public authorities to consider both monitored and unmonitored information sources in relation to smoking prevalence in adolescents. These results imply that information emanating from monitored sources of information in the design and implementation of measures against adolescents' tobacco use.

Role of specific immunoglobulin-E in chronic rhinosinusitis: Its clinical relevance according to nasal challenge test.

Background: Guidelines for chronic rhinosinusitis (CRS) propose total IgE and eosinophils as important biomarkers to identify type-2 inflammation. Despite the fact that specific IgE (sIgE) have been identified as a clinical predictor in some type-2 diseases for different clinical outcomes, its role in CRS has yet to be explored in detail. Objetive: To describe systemic and local sIgE in CRS and explore its possible association with clinical outcomes using nasal challenge tests (NCT). Methods: In CRS patients, we measure total IgE, serum sIgE (SsIgE) and nasosinusal sIgE (NsIgE) against 9 allergenic sources; Der p, Der f, Blo t, Can f, Fel d, Per a, grasses, Staphylococcus enterotoxin A, and B. NCT was done using the allergen with the higher sIgE prevalence (Der p). Results: A total of 174 patients were included. Prevalence of SsIgE was 52.8% and NsIgE 46.5%; Der p was the principal allergen for SsIgE and NsIgE. The presence of nasal polyps, asthma comorbidity, NSAID hypersensitivity, and hyposmia, were significantly associated with the presence of SsIgE and NsIgE but not with total IgE. NCT-Der p was performed in 73 CRS patients, being positive in 33 (45.2%). SsIgE have the best diagnostic accuracy (79.4%) to predict NCT results (NsIgE 67.5% total IgE 52%). Conclusion: Specific IgE is a better biomarker in CRS than total IgE. Patients with clinically relevant SsIgE have a pheno-endotype associated with different clinical outcomes. Considering the clinical relevance of SsIgE demonstrated by NCT, interventions like allergen immunotherapy in CRS must be study.

Explanatory factors of polydrug use in mid-late teens and the relevance of information sources: Correlational and configurational assessment in Tarragona (Spain).

Background: Substance use among adolescents is a public health problem, and the simultaneous use of multiple substances aggravates this problem. Although the facilitators of specific substance use in adolescents have been widely investigated, polydrug use is a less common topic. Likewise, the role that the origin of the information available to adolescents regarding substance use plays in relation to polydrug use is practically unexplored. Objectives: This work analyzed the relevance of the origin of the information sources available to adolescents regarding substance use, among which we distinguished those that were monitored (or supervised) by public agencies from those that were unmonitored (or unsupervised) in the consumption of more than one substance. As control variables, we considered three individual factors and four environmental factors. The relevance of these sources was analysed from a dual perspective: on the one hand, their statistical relevance was measured, and on the other hand, how they combined with the control variables was analysed to identify risk and risk-free profiles in substance poly-drug use. Methods: This paper utilized a sample of N = 573 adolescents aged ≥17 years. This sample was collected from a survey administered in the spring of 2023. We examined the impact of unmonitored information sources (peers, siblings, and the Internet) and supervised sources (school, parents, and media) on the combined consumption of alcohol, tobacco, and cannabis. Additionally, we took three individual factors (gender, early onset of alcohol, and tobacco use) and four environmental factors (parental control, alcohol, tobacco, and cannabis use among peers) into account as control variables. Initially, we conducted a regression analysis to adjust for the impact of these factors on polydrug use. Subsequently, we employed a fuzzy set qualitative analysis (fsQCA) to investigate how predictor factors combined with the formation of adolescent profiles associated with polydrug consumption and nonconsumption. Results: Unmonitored information sources were associated with a greater incidence of poly consumption, with ORs of 1.703 and p values of 0.004. However, the protective effects of regulated information sources remained ambiguous. Among the variables positively linked with of polydrug use, are female sex (OR = 1.329, p = 0.0076), early alcohol consumption (OR = 4.680, p < 0.0001), and early tobacco consumption (OR = 3.242, p < 0.001) were the most important. Peer drinking (OR = 1.556, p = 0.0187) and peer cannabis use (OR = 1.351, p = 0.0226) were also significantly correlated. The use of the fsQCA made it possible to identify the profiles of adolescents associated to polysubstance use and non-use. The conditions of the configurations that explained use were characterized by an early onset of the joint consumption of tobacco and alcohol. The profile of non-consuming adolescents is that of adolescents whose peers do not use tobacco or cannabis and who have parental control and monitored sources.

Azatriangulene-Based Conductive C═C Linked Covalent Organic Frameworks with Near-Infrared Emission.

Two near-infrared (NIR) emissive π-conjugated covalent organic frameworks (COFs) pTANG1 and pTANG2 are synthesized using Knoevenagel condensation of trioxaazatriangulenetricarbaldehyde (TATANG) with benzene- and biphenyldiacetonitriles, respectively. The morphology of the COFs is affected by the size of TATANG precursor crystals. Donor-acceptor interactions in these COFs result in small bandgaps (≈1.6 eV) and NIR emission (λmax = 789 nm for pTANG1). pTANG1 can absorb up to 9 molecules of water per unit cell, which is accompanied by a marked quenching of the NIR emission, suggesting applications as humidity sensors. p-Doping with magic blue significantly increases the electrical conductivities of the COFs by up to 8 orders of magnitude, with the room temperature conductivity of pTANG1 reaching 0.65 S cm-1, the highest among reported C═C linked COFs. 1H NMR relaxometry, temperature-dependent fluorescence spectroscopy, and DFT calculations reveal that the higher rigidity of the shorter phenylene linker is responsible for the more extended conjugation (red-shifted emission, higher electrical conductivity) of pTANG1 compared to pTANG2.

Quinoxaline 1,4-di-N-oxide Derivatives as New Antinocardial Agents.

Mycetoma is currently considered as a neglected tropical disease. The incidence of mycetoma is unknown but most of the worldwide cases are present in the "mycetoma belt" including countries like Mexico, India, Senegal, and others. The treatment of mycetoma depends on the etiological agent responsible for the case. Treatment success reaches 60 to 90%; however, common treatment has been reported to be ineffective in some cases, due in part to resistance to the prescribed antibiotics. Therefore, it is necessary to develop new therapeutic options. In the past two decades, quinoxaline derivatives have shown relevance as antibacterial agents. Therefore, in this work, esters of quinoxaline 1,4-di-N-oxide derivatives were evaluated in vitro against the reference strain CECT-3052 from N. brasiliensis, six clinical isolates, and macrophages J774A.1 to determine their cytotoxicity and security index. Additionally, nine reference drugs were evaluated as controls. The results show that nine esters of quinoxaline 1,4-di-N-oxide derivatives had a minimum inhibitory concentration (MIC) < 1 µg/mL against the reference strain and four of them (N-05, N-09, N-11, and N-13) had an MIC < 1 µg/mL against the clinical isolates. Therefore, the scaffold quinoxaline 1,4-di-N-oxide could be used to develop new and more potent antinocardial agents.

Diagnostic Accuracy of Ultrasound Imaging and Shear Wave Elastography to Discriminate Patients with Chronic Neck Pain from Asymptomatic Individuals.

OBJECTIVES: The aim of this study was to determine and compare the capability of several B-mode ultrasound (US) and shear wave elastography (SWE) metrics to differentiate subjects with chronic non-specific neck pain from asymptomatic subjects. METHODS: A diagnostic accuracy study recruiting a sample of patients with chronic neck pain and asymptomatic controls was conducted. Data collection included sociodemographic information (i.e., gender, age, height, weight and body mass index), clinical information (pain intensity assessed using the Visual Analogue Scale and pain-related disability using the Neck Disability Index) and B-mode ultrasound and shear wave elastography features of the cervical multifidus muscle (cross-sectional area, perimeter, mean echo intensity, fat infiltration, shear wave speed and Young's modulus). After analyzing between-group differences for left/right sides, cases and controls, and males and females, the area under the receiver operating characteristic (ROC) curve, the optimal cut-off point, the sensitivity, the specificity, the positive likelihood ratio (LR) and negative LR for each metric were calculated. A total of 316 individuals were recruited in this study (n = 174 cases with neck pain and n = 142 asymptomatic controls). RESULTS: No significant differences (p > 0.05) were found between cases and controls for most variables, except for fatty infiltration, which was significantly higher in chronic neck pain cases (p < 0.001). Gender differences were significant across all US and SWE metrics (all, p < 0.001 except p = 0.015 for fatty infiltrates). A slight asymmetry was observed between the left and right sides for area (p = 0.038). No significant interactions between group, gender and side (all metrics, p > 0.008) were identified. Fatty infiltration was the most effective discriminator, with a ROC value of 0.723, indicating acceptable discrimination. The optimal cut-off point for fatty infiltration was 25.77, with a moderate balance between sensitivity (59.8%) and specificity (20.5%). However, its positive likelihood ratio (LR) of 0.75 suggests limited usefulness in confirming the condition. CONCLUSIONS: Fatty infiltration was significantly higher in individuals with chronic idiopathic neck pain compared to those without symptoms, while other muscle metrics were similar between both groups. However, since fat infiltration had moderate diagnostic accuracy and the other metrics showed poor discriminatory power, US cannot be used solely to discriminate patients with idiopathic neck pain.

Changes in Prevalence of IgE Sensitization and Allergenic Exposition over a 10-Year Period in a Tropical Region.

INTRODUCTION: Multiple antigen environmental sources have been identified as possible causes of allergies, but few studies have evaluated changes in the sensitization profiles over time. The aim of this study was to evaluate the changes in IgE sensitization and exposure to dust mites, cats, dogs, and cockroaches over a 10-year period. METHODS: During a period of 10 years among patients with asthma, rhinitis and/or atopic dermatitis, we evaluated the annual frequency of atopy to Dermatophagoides farinae, Dermatophagoides pteronyssinus, Blomia tropicalis, Canis familiaris, Felis domesticus and cockroaches (Periplaneta americana and Blatella germanica). Exposure to sources was also assessed using questionnaires (Pets) or direct counts (House dust mites and cockroaches). The association between some risk factors and the prevalence of atopy was explored. RESULTS: A total of 6,000 records were included. Among the patients, 82% had IgE sensitization to at least one of the six allergenic sources. Sensitization to Dermatophagoides spp. was the most frequent (>78%). Exposure and sensitization in the first decade of life to Dermatophagoides spp. seem to determine the molecular spreading to other allergenic sources. Exposure to Blomia tropical increases significantly over time (year 2015; 38% vs. year 2022; 51%, p 0.03). Exposure to dogs was higher than with cats but association between atopy and exposure was stronger with cats (OR 27.4, 95% CI: 22.3-33.6, p < 0.01). CONCLUSION: Exposure and sensitization in the first decade of life to Dermatophagoides spp. determine the molecular spreading of IgE antibodies to other allergenic sources. Household exposure to dogs and cats seems to be important for the subsequent development of atopy. Sensitization to B. tropicalis and cockroach appears to be mostly from cross-reactivity rather than direct exposure.

In silico analysis of molecular mimicry between human aquaporin 3, Aspergillus fumigatus aquaporin and aquaporins from allergic sources.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin condition that has a significant impact on quality of life. The immune response and allergy symptoms in AD are triggered by the recognition of specific allergens by IgE antibodies. Cross-reactivity can lead to auto-IgE responses, potentially worsening AD symptoms. Our research aimed to enhance our understanding of allergenic sources, including A. fumigatus, and their role in AD. We focused on molecular mimicry between human AQP3 and A. fumigatus aquaporin. Methods: In our in-silico analysis, we compared the amino acid sequences of human aquaporin 3 (AQP3) and A. fumigatus aquaporin with 25 aquaporins from various allergenic sources, sourced from the UniProt and NCBI databases. Phylogenetic relationship analysis and homology-based modeling were conducted. We identified conserved antigenic regions located within the 3D structures. Results: The global identity levels among the studied aquaporins averaged 32.6%. One antigenic site exhibited a remarkable local region, with a conserved identity of 71.4%. We categorized the aquaporins into five monophyletic clades (A-E), with group B showing the highest identity (95%), including six mammalian aquaporins, including AQP3. When comparing A. fumigatus aquaporins, the highest identity was observed with Malassezia sympodialis at 35%. Both human and A. fumigatus aquaporins have three linear and three discontinuous epitopes. Conclusions: We identified potential linear and conformational epitopes of AQP3, indicating a possible molecular mimicry between humans and A. fumigatus aquaporins. This suggests autoreactivity and potential cross-reactivity, although further validation using in vitro and in vivo experiments is required.

Apraisal of the diagnostic value of the gag reflex in patients with neurogenic oropharyngeal dysphagia / Evaluación del valor clínico del reflejo nauseoso en la disfagia orofaríngea neurogénica.

Introduction: The gag reflex is a protection mechanism that prevents food and unwanted agents from entering the lower airways. It is usually part of the physical examination of swallowing to detect oropharyngeal dysphagia, but it is a potentially ambiguous sign. Objective: To evaluate the diagnostic value of the gag reflex in patients with neurogenic oropharyngeal dysphagia and adults without it. Materials and methods: We conducted an analytical observational study in patients with neurogenic oropharyngeal dysphagia (cases) and patients without dysphagia (controls). We evaluated the absence or presence of the reflex bilaterally, by direct visualization, and adjusted it according to sex, age, and other interaction variables. Results: We included 86 patients with neurogenic oropharyngeal dysphagia and 80 control subjects. The gag reflex on swallowing physical examination showed a positive relationship with the patients (right side: OR = 3.97; 95 % CI: 2.01-7.84; left side: OR = 4.84; 95 % CI: 2.41-9.72), but a negative association with the control group. In both groups, neither sex, nor age, nor other interaction variables modified the gag reflex. Conclusions: The gag reflex absence or presence does not confirm or exclude the existence of oropharyngeal dysphagia due to neurological and neuromuscular causes. Therefore, health professionals must not rely on this reflex. Clinicians must go beyond a simple reflex revision, even in neurological patients where it is supposed to be absent.

Introducción. El reflejo nauseoso es un mecanismo de protección que impide que alimentos y agentes no deseados penetren en la vía aérea inferior. Usualmente, hace parte del examen físico de la deglución para detectar la disfagia orofaríngea, pero es un signo potencialmente ambiguo. Objetivo. Evaluar el valor diagnóstico del reflejo nauseoso en pacientes con disfagia orofaríngea neurogénica y en pacientes sin ella. Materiales y métodos. Se trata de un estudio observacional, analítico, en pacientes con disfagia orofaríngea neurogénica (casos) y en personas sin disfagia (controles), en el cual se evaluó por visualización directa la ausencia o la presencia del reflejo nauseoso de forma bilateral. Este resultado se ajustó por sexo, edad y otras variables de interacción. Resultados. Se evaluaron 86 pacientes con disfagia orofaríngea neurogénica y 80 personas sin ella. En el examen físico de la deglución, la presencia del reflejo mostró una relación positiva con los pacientes (lado derecho: OR = 3,97; IC95%: 2,01-7,84; lado izquierdo: OR = 4,84; IC95%: 2,41-9,72), pero una asociación negativa con los controles. En ambos grupos, ni el sexo ni la edad, ni otras variables de interacción modificaron el reflejo nauseoso. Conclusiones. La ausencia o la presencia del reflejo nauseoso no confirma ni excluye la existencia de una disfagia orofaríngea por causas neurológicas o neuromusculares; por lo tanto, no es recomendable que los profesionales de la salud se fíen del resultado de este reflejo. Los médicos tratantes deben ir más allá de una simple revisión del reflejo nauseoso, incluso en pacientes neurológicos en quienes se supone que debería estar ausente.

Efficacy and safety of dynamic arterial elastance for weaning vasopressor support in septic shock patients: a randomised controlled trial protocol.

INTRODUCTION: The dynamic arterial elastance (EaDyn), calculated as pulse pressure variation divided by stroke volume variation, has been studied as a predictor of vasopressor weaning. However, its potential as a haemodynamic tool for tapering off vasopressors in patients with sepsis remains unexplored. Therefore, our study aimed to assess whether using EaDyn for weaning vasopressor support could reduce the duration of vasopressor support in patients with sepsis. METHODS AND ANALYSIS: This pragmatic single-centre controlled clinical trial will take place at Fundación Santa Fe de Bogotá, Colombia. Adult patients diagnosed with septic shock according to the sepsis-3 criteria and a Sequential Organ Failure Assessment score ≥4 will be included. A total of 114 patients (57 per group) will undergo conventional critical care monitoring, and the weaning of vasopressor support will be initiated based on the EaDyn or mean arterial pressure (MAP), depending on the assigned group. EaDyn will be estimated based on the measurements obtained from a PiCCO device connected to a PulsioFlex Monitoring Platform (PULSION Medical Systems SE, Feldkirchen, Germany). Our primary outcome is the difference in vasopressor support duration between the EaDyn and MAP groups.Participants and statisticians performing the statistical analysis will be blinded to the group allocation. Dependent and independent variables will be analysed through univariate and multivariate statistical tests. Since we will perform three repeated measurements for analysis, we will implement a Bonferroni post hoc correction. Additionally, Cox regression and Kaplan-Meier analyses will be conducted to address objectives related to time. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee at Fundación Santa Fe de Bogotá (CCEI-16026-2024). Written informed consent will be obtained from all participants. The results will be disseminated through publication in peer-reviewed journals and presentations at national and international events. TRIAL REGISTRATION NUMBER: NCT06118775.

Psychological resilience, athletic experience, and competitive level of judokas. A transversal study.

Introduction: While there is agreement on the positive link between psychological resilience and athletic performance, conclusive findings regarding the association between psychological resilience and other variables of interest (for example, age, gender, type of sport, or competitive level) remain elusive. Objective: The study aimed to assess psychological resilience levels among judokas and explore potential associations with demographic factors, judo experience and competitive level. Methods: A total of 702 judokas (469 men and 233 women) participated in the study, of whom 194 (27.6%) were classified as TOP by their competitive level. Psychological resilience was evaluated using the Spanish version of the 10 item Connor-Davidson Resilience Scale (CD-RISC 10), with a score range from 0 to 40. Independent T-test and Pearson's coefficient were used for bivariate analysis. A two-way non-parametric ANCOVA was carried out to analyse the impact of gender and competitive level on psychological resilience. Results: The judokas showed total mean scores in the CD-RISC 10 of 33.08 points (SD = 4.79), considered high. Levels of psychological resilience were significantly higher among men (33.36 ± 4.76) than women (32.53 ± 4.80) and were positively correlated with age and number of years practicing and competing in Judo (p = 0.019). Judokas with a higher competitive level (TOP judokas) showed significantly higher levels of resilience than the others (non-TOP judokas) (p < 0.001). These differences in resilience according to competitive level persisted, among both men and women, when adjusting the model of analysis (two-way ANCOVA) for all variables considered in the study, although with a small effect size. Conclusion: The results suggest that the practice of Judo, especially over long periods of time, is associated with high scores in psychological resilience. Furthermore, psychological resilience appears to be a differentiating variable among judokas at a high-competitive level, and its evaluation and development using different strategies based on age and gender should be considered by trainers and psychologists.

A Paradox Unveiled: A Case Report of Cerebral Infarctions in a Patient With Severe Thrombocytopenia.

Thrombocytopenia is a condition in which the platelet count is less than 150,000/µL, which can be congenital or acquired. The condition can be further sub-classified. Nevertheless, the causes include infection, medication-mediated, liver diseases, or heart diseases. Moreover, diagnosis is straightforward only on a few occasions. Here, we are presenting a patient with a conundrum of immune thrombocytopenia (ITP) and a stroke. A 75-year-old female patient with a past medical history of hypertension was brought to the emergency department (ED) for altered mental status (AMS). Initial blood workup showed a platelet count of 27,000/µL and hemoglobin level of 6.2 g/dl, and brain magnetic resonance imaging (MRI) revealed ischemic stroke. Rarely, ITP patients can paradoxically develop arterial and venous thrombosis. Hence, physicians must remain vigilant in promptly and accurately diagnosing thrombotic events in ITP to ensure appropriate treatment, including antiplatelet and anticoagulant therapy, alongside ITP-specific interventions to improve outcomes.

Flour Fortification Using Lablab Purpureus Evaluation with a Biosensor.

BACKGROUND/AIMS: Due to rapid metabolic and growth rates during the first two years of life, the nutritional needs of young children are high. Given the small portion sizes consumed by children between the ages of 6 and 24 months, it is necessary to improve diets to meet the nutritional needs of this age group. Therefore, the analysis of lysine content is an important parameter in the evaluation of enriched foods. METHODS: The utilization of an enzymatic sensor employing lysine-α-oxidase (LOx) as a biorecognition element represents an alternative to the existing methods. This sensor was optimized for quantifying the lysine content in flour mixtures: Quinoa-Lablab purpureus rye - Lablab purpureus, and pole beans - Lablab purpureus, with a maximum ratio of 85g/100g. RESULTS: The addition of lablab purpureus significantly increased the lysine concentration in the enriched samples. When 30 percent was substituted in quinoa, it reached a 143 percent increase. And when 15 percent was substituted in the rye flour, the final concentration of this amino acid increased by 64 percent. In order to quantify the lysine concentration, it was necessary to optimize various parameters during the use of the sensor, e.g. a potentiometric signal was detected upon the depletion of oxygen present during the oxidation of lysine in the samples, and the sensor response was recorded at 2 s. This was possible due to the modification of the pH and the thickness of the membrane. The oxidation of lysine is catalyzed by LOx using molecular oxygen as the electron acceptor. The corresponding acidic compounds and hydrogen peroxide were formed in the reaction medium. CONCLUSION: It was possible to increase and verify the concentration of lysine in all the flours tested through the use of the biosensor, which turned out to be a valid method for controlling the nutritional quality of flours.

Primary aldosteronism prevalence enhanced by strict adherence to 2016 Endocrine Society guidelines: insights from an endocrine hypertension unit.

INTRODUCTION: Primary aldosteronism is the most frequent cause of hypertension although is undetected. The 2016 Endocrine Society guidelines (2016-ESG) recommendations for primary aldosteronism detection are unfulfilled. We aimed to ascertain the prevalence of primary aldosteronism, following the screening criteria endorsed by the 2016-ESG. METHODS: All adult patients tested for primary aldosteronism at an endocrine hypertension unit of a tertiary hospital during 2021-2023 were studied. Primary aldosteronism investigation was performed when at least one reason for its screening based on 2016-ESG was detected. When screening was positive, confirmatory tests were executed. Rates and diagnostic accuracy of the reasons for primary aldosteronism screening were analyzed. RESULTS: Two hundred and sixty-five patients were included. Mean age was 55 ±â€Š14 years, 124 of 265 (46.8%) were women, 24.6% had hypokalemia, and 16% adrenal incidentaloma(s) as indication for screening. Primary aldosteronism was diagnosed in 122 of 265 (46%). The presence of each reason for primary aldosteronism screening increased the probability of primary aldosteronism in 2.2-fold [95% confidence interval (CI): 1.63 to 2.97; P < 0.001]. The most frequent reason for primary aldosteronism screening was a blood pressure at least 150/100 mmHg on three measurements on different days, and had a sensitivity of 95%. Hypertension with spontaneous or diuretic-induced hypokalemia was the most specific reason (87.5%) but was not frequent. Adrenal incidentaloma(s) was not associated with primary aldosteronism diagnosis. CONCLUSION: Primary aldosteronism prevalence is markedly high when the 2016-ESG recommendations are rigorously implemented. The greater the number of indications for primary aldosteronism investigation, the higher its prevalence. Further studies are needed to corroborate this observed primary aldosteronism prevalence.
