An ecological assessment of decision-making under risk and ambiguity through the virtual serious game Kalliste Decision Task.

Traditional methods for evaluating decision-making provide valuable insights yet may fall short in capturing the complexity of this cognitive capacity, often providing insufficient for the multifaceted nature of decisions. The Kalliste Decision Task (KDT) is introduced as a comprehensive, ecologically valid tool aimed at bridging this gap, offering a holistic perspective on decision-making. In our study, 81 participants completed KDT alongside established tasks and questionnaires, including the Mixed Gamble Task (MGT), Iowa Gambling Task (IGT), and Stimulating & Instrumental Risk Questionnaire (S&IRQ). They also completed the User Satisfaction Evaluation Questionnaire (USEQ). The results showed excellent usability, with high USEQ scores, highlighting the user-friendliness of KDT. Importantly, KDT outcomes showed significant correlations with classical decision-making variables, shedding light on participants' risk attitudes (S&IRQ), rule-based decision-making (MGT), and performance in ambiguous contexts (IGT). Moreover, hierarchical clustering analysis of KDT scores categorized participants into three distinct profiles, revealing significant differences between them on classical measures. The findings highlight KDT as a valuable tool for assessing decision-making, addressing limitations of traditional methods, and offering a comprehensive, ecologically valid approach that aligns with the complexity and heterogeneity of real-world decision-making, advancing research and providing insights for understanding and assessing decision-making across multiple domains.

Point-of-care ultrasonography in Ukraine: a survey of anesthesiologists-intensivists participating in ultrasonography courses.

PURPOSE: Despite the potential value of point-of-care ultrasonography (POCUS) in resource-limited environments, it is not widely used in low- and middle-income countries compared with high-income countries. We sought to evaluate the current POCUS practice of Ukrainian anesthesiologists who attended POCUS courses to guide future POCUS training in Ukraine. METHODS: We conducted a 25-question web-based survey. It was distributed to 255 participants of POCUS courses held in Ukraine in 2023. The survey sections described current POCUS practice, perception of POCUS value, POCUS skills self-assessment, and perceived barriers to implementing POCUS in clinical practice. RESULTS: Two hundred and forty-four out of 255 course participants completed the survey, representing 214 unique respondents. Those who self-rated their skills identified themselves as either novices or beginners in areas of POCUS knowledge (118/157, 75%), image acquisition (110/158, 70%), image interpretation (117/158, 74%), and integration into clinical decision-making (105/155, 68%). Among all survey responders, 55% (118/214) reported using POCUS for vascular access procedures, 45% (97/214) for trauma assessment, and 44% (93/214) for regional anesthesia. Reported barriers to POCUS implementation included lack of ultrasound devices (101/214, 47%) and lack of trained faculty (112/214, 52%). CONCLUSION: Among anesthesiologists who participated in POCUS courses in Ukraine, the majority were in early stages of ultrasound practice. Respondents identified POCUS applications not currently practiced and evaluated barriers to POCUS use. Based upon these survey findings, we propose the following measures in Ukraine: 1) developing a standardized national POCUS curriculum; 2) increasing the number of experienced instructors of POCUS; and 3) acquiring ultrasound devices to support clinical applications of POCUS, especially in the Central, Southern, and Eastern regions.

RéSUMé: OBJECTIF: Malgré la valeur potentielle de l'échographie ciblée (POCUS) dans les environnements à ressources limitées, cette modalité n'est pas très répandue dans les pays à revenu faible et intermédiaire par rapport aux pays à revenu élevé. Nous avons cherché à évaluer la pratique actuelle des anesthésiologistes en Ukraine qui ont suivi des cours d'échographie ciblée afin d'orienter la future formation en POCUS dans ce pays. MéTHODE: Nous avons mené un sondage en ligne de 25 questions. Il a été distribué à 255 personnes ayant suivi des cours de POCUS organisés en Ukraine en 2023. Les sections de l'enquête décrivaient la pratique actuelle en échographie ciblée, la perception de sa valeur, l'auto-évaluation des compétences en POCUS et les obstacles perçus à sa mise en œuvre dans la pratique clinique. RéSULTATS: Deux cent quarante-quatre des 255 personnes ayant pris part au cours ont répondu au sondage, représentant 214 répondant·es uniques. Les personnes ayant auto-évalué leurs compétences se sont identifiées comme novices ou débutantes dans les domaines de la connaissance de l'échographie ciblée (118/157, 75 %), de l'acquisition d'images (110/158, 70 %), de l'interprétation d'images (117/158, 74 %) et de l'intégration dans la prise de décision clinique (105/155, 68 %). Parmi toutes les personnes ayant répondu à l'enquête, 55 % (118/214) ont déclaré utiliser l'échographie ciblée pour les procédures d'accès vasculaire, 45 % (97/214) pour l'évaluation des traumatismes et 44 % (93/214) pour l'anesthésie régionale. Les obstacles signalés à la mise en œuvre de l'échographie ciblée comprenaient le manque d'appareils d'échographie (101/214, 47 %) et le manque de professeur·es formé·es (112/214, 52 %). CONCLUSION: Parmi les anesthésiologistes qui ont participé aux cours d'échographie ciblée en Ukraine, la majorité en étaient aux premiers stades de la pratique de l'échographie. Les répondant·es ont identifié les applications de l'échographie ciblée qui ne sont pas actuellement pratiquées et ont évalué les obstacles à son utilisation. Sur la base des résultats de cette enquête, nous proposons les mesures suivantes en Ukraine : 1) la création d'un programme national normalisé d'échographie ciblée; 2) l'augmentation du nombre d'instructrices et instructeurs expérimenté·es en échographie ciblée; et 3) l'acquisition d'appareils d'échographie pour soutenir les applications cliniques de cette modalité, en particulier dans les régions du Centre, du Sud et de l'Est du pays.

Natural variation in response to combined water and nitrogen deficiencies in Arabidopsis.

Understanding plant responses to individual stresses does not mean that we understand real world situations, where stresses usually combine and interact. These interactions arise at different levels, from stress exposure to the molecular networks of the stress response. Here, we built an in-depth multi-omics description of plant responses to mild water (W) and nitrogen (N) limitations, either individually or combined, among five genetically different Arabidopsis (Arabidopsis thaliana) accessions. We highlight the different dynamics in stress response through integrative traits such as rosette growth and the physiological status of the plants. We also used transcriptomics and metabolomics profiling during a stage when the plant response was stabilized to determine the wide diversity in stress-induced changes among accessions, highlighting the limited reality of a 'universal' stress response. The main effect of the WxN interaction was an attenuation of the N-deficiency syndrome when combined with mild drought, but to a variable extent depending on the accession. Other traits subject to WxN interactions are often accession-specific. Multi-omics analyses identified a subset of transcript-metabolite clusters that are critical to stress responses but essentially variable according to the genotype factor. Including intra-specific diversity in our descriptions of plant stress response places our findings in perspective.

Right Bundle Branch Block Predicts Appropriate Implantable Cardioverter Defibrillator Therapies in Patients with Non-Ischemic Dilated Cardiomyopathy and a Prophylactic Implantable Cardioverter Defibrillator.

Background: The benefit of prophylactic implantable cardioverter defibrillators (ICDs) in patients with severe systolic dysfunction of non-ischemic origin is still unclear, and the identification of patients at risk for sudden cardiac death remains a major challenge. Aims/Methods: We retrospectively reviewed all consecutive patients with non-ischemic dilated cardiomyopathy (NICM) who underwent prophylactic ICD implantation between 2008 and 2020 in two tertiary centers. Our main goal was to identify the predictors of appropriate ICD therapies (anti-tachycardia pacing [ATP] and/or shocks) in this cohort of patients. Results: A total of 224 patients were included. After a median follow-up of 51 months, 61 patients (27.2%) required appropriate ICD therapies. Patients with appropriate ICD therapies were more frequently men (87% vs. 69%, p = 0.006), of younger age (59 years, (53-65) vs. 64 years, (57-70); p = 0.02), showed more right bundle branch blocks (RBBBs) (15% vs. 4%, p = 0.007) and less left bundle branch blocks (LBBBs) (26% vs. 47%, p = 0.005) in the ECG, and had higher left ventricular end-diastolic (100 mL/m2, (90-117) vs. 86, (71-110); p = 0.011) and systolic volumes (72 mL/m2, (59-87) vs. 61, (47-81), p = 0.05). In a multivariate competing-risks regression analysis, RBBB (HR 2.26, CI 95% 1.02-4.98, p = 0.043) was identified as an independent predictor of appropriate ICD therapies. Conclusion: RBBBs may help to identify patients with NICM at high risk of ventricular arrhythmias and requiring ICD intervention.

Building a High-Potential Silver-Sulfur Redox Reaction Based on the Hard-Soft Acid-Base Theory.

Sulfur holds immense promise for battery applications owing to its abundant availability, low cost, and high capacity. Currently, sulfur is commonly combined with alkali or alkaline earth metals in metal-sulfur batteries. However, these batteries universally face challenges in cycling stability due to the inevitable issue of polysulfide dissolution and shuttling. Additionally, the inferior stability of metal sulfide discharge compounds results in low S0/S2- redox potentials (<-0.41 V vs SHE). Herein, we leverage the principle of the hard-soft acid-base theory to introduce a novel silver-sulfur (Ag-S) battery system, which operates on the reaction between the soft acid of Ag+ and the soft base of S2-. Due to their high reaction affinity, the discharge compound of silver sulfide (Ag2S) is intrinsically insoluble and fundamentally stable. This not only resolves the polysulfide dissolution issue but also leads to a predominantly high S0/S2- redox potential (+1.0 V vs. SHE). We thus exploit the Ag-S reaction for a primary zinc battery application, which exhibits a high capacity of ∼620 mAh g-1 and a high voltage of ∼1.45 V. This work offers valuable insights into the application of classic chemistry theories in the development of innovative energy storage devices.

Calcifediol or Corticosteroids in the Treatment of COVID-19: An Observational Study.

Medical treatment of coronavirus 19 disease (COVID-19) is a therapeutic challenge. The available data strongly suggest that calcifediol treatment may reduce the severity of COVID-19, and corticosteroids are the treatment of choice worldwide for severe COVID-19. Both have a very similar action profile, and their combined use in patients may modify the contribution of each administered compound. OBJECTIVE: To evaluate how treatment with calcifediol and/or corticosteroids in medical practice modified the need for ICU admission, death, or poor prognosis of patients hospitalized with COVID-19 during the first outbreaks. DESIGN, PATIENTS AND SETTING: A retrospective observational cohort study of patients admitted for COVID-19 to the Pneumology Unit of the Hospital Universitario Reina Sofía (Córdoba, Spain). INTERVENTIONS: Patients were treated with calcifediol or/and corticosteroids with the best available therapy and standard care, according to clinical practice guidelines. MEASUREMENTS: Admission to the intensive care unit (ICU) or death during hospitalization and poor prognosis. RESULTS: Seven hundred and twenty-eight patients were included. According to the treatment received, they were included in four groups: calcifediol (n = 68), glucocorticoids (n = 112), both (n = 510), or neither (n = 38). Of the 578 patients treated with calcifediol, 88 were admitted to the ICU (15%), while of the 150 not treated with calcifediol, 39 required ICU admission (26%) (p < 0.01). Among the patients taking calcifediol without glucocorticoids, only 4 of 68 (5.8%) required ICU admission, compared to 84 of 510 (16.5%) treated with both (p = 0.022). Of the 595 patients who had a good prognosis, 568 (82.01%) had received treatment with calcifediol versus the 133 patients with a poor prognosis, of whom 90 (67.66%) had received calcifediol (p < 0.001). This difference was not found for corticosteroids. INTERPRETATION: The treatment of choice for hospitalized patients with moderate or mild COVID-19 could be calcifediol, not administering corticosteroids, until the natural history of the disease reaches a stage of hyperinflammation.

Leprosy in Spain: A Descriptive Study of Admissions at Fontilles Sanatorium between 1909 and 2020.

BACKGROUND: The study aimed to characterize patients with leprosy admitted to Fontilles throughout the 20th and 21st centuries, focusing on differences across three periods (I, II, and III). It also explored variables linked to patient survival. METHODS: This was a retrospective descriptive study analyzing the medical records of Fontilles patients from 1909 to 2020. It assessed 26 clinical, sociodemographic, and temporal variables (n = 2652). RESULTS: Most patients were male, single, multibacillary (MB), and farmers, from Andalusia and the Valencian Community. The origin of patients shifted over time towards being mostly foreign-born in period III. More than a half were previously admitted and had family members with leprosy. While leprosy reactions decreased over time, neurological symptoms were increasingly diagnosed. The age at onset, admission, and death increased progressively over time. The survival of patients with leprosy at Fontilles depended on the age at admission and the period. CONCLUSIONS: Improved knowledge, services, and awareness regarding leprosy led to increased age at onset and more favorable outcomes. The prolonged time between symptom onset and diagnosis indicates that leprosy is still a neglected disease. Although MB forms are more severe, leprosy classification did not significantly impact the survival rates of patients at Fontilles.

Physiotherapists' adherence to Clinical Practice Guidelines in fibromyalgia: a cross-sectional online survey.

To evaluate the level of knowledge and adherence to Clinical Practice Guidelines on fibromyalgia of physiotherapists in Spain. A cross-sectional study using an ad-hoc online survey was implemented to assess aspects on the assessment, treatment, and decision of the length of the therapeutic approach on fibromyalgia. Based on the results, professionals were classified as adherent, partially adherent, or non-adherent. The level of agreement with several statements on the condition was also evaluated across the professionals surveyed to evaluate the potential consensus. A total of 240 physiotherapists met inclusion criteria, amongst which 68 (28.33%) were adherent. The academic level of studies (Chi-square = 48.601, p-value = 0.001) and having had previous training in fibromyalgia (Chi-square = 151.011, p-value = 0.001) displayed statistically significant differences across adherence-based groups. Consensus was reached for 15 out of 24 statements. Our findings highlight the presence of an acceptable level of knowledge and adherence to clinical practice guidelines in the field of fibromyalgia among physiotherapists in Spain.Practice implicationsOur results also reveal the existence of an evidence-to-practice gap in the field, with potential room for improvement: further efforts on promoting and reinforcing the importance of evidence-based therapies are needed, from university teaching plans to clinical updates for daily practice.

A review on the immobilization of bromelain.

This review shows the endeavors performed to prepare immobilized formulations of bromelain extract, usually from pineapple, and their use in diverse applications. This extract has a potent proteolytic component that is based on thiol proteases, which differ depending on the location on the fruit. Stem and fruit are the areas where higher activity is found. The edible origin of this enzyme is one of the features that determines the applications of the immobilized bromelain to a more significant degree. The enzyme has been immobilized on a wide diversity of supports via different strategies (covalent bonds, ion exchange), and also forming ex novo solids (nanoflowers, CLEAs, trapping in alginate beads, etc.). The use of preexisting nanoparticles as immobilization supports is relevant, as this facilitates one of the main applications of the immobilized enzyme, in therapeutic applications (as wound dressing and healing components, antibacterial or anticancer, mucus mobility control, etc.). A curiosity is the immobilization of this enzyme on spores of probiotic microorganisms via adsorption, in order to have a perfect in vivo compatibility. Other outstanding applications of the immobilized enzyme are in the stabilization of wine versus haze during storage, mainly when immobilized on chitosan. Curiously, the immobilized bromelain has been scarcely applied in the production of bioactive peptides.

Reducing intersectional stigma among transgender women in Brazil to promote uptake of HIV testing and PrEP: study protocol for a randomised controlled trial of Manas por Manas.

INTRODUCTION: Globally, transgender ('trans') women experience extreme social and economic marginalisation due to intersectional stigma, defined as the confluence of stigma that results from the intersection of social identities and positions among those who are oppressed multiple times. Among trans women, gender-based stigma intersects with social positions such as engagement in sex work and substance use, as well as race-based stigma to generate a social context of vulnerability and increased risk of HIV acquisition. In Brazil, trans women are the 'most at-risk' group for HIV, with 55 times higher estimated odds of HIV infection than the general population; further, uptake of HIV testing and pre-exposure prophylaxis (PrEP) among trans women is significantly lower than other at-risk groups. Through extensive formative work, we developed Manas por Manas, a multilevel intervention using HIV prevention strategies with demonstrated feasibility and acceptability by trans women in Brazil, to address intersectional stigma and increase engagement in the HIV prevention continuum. METHODS AND ANALYSIS: We are conducting a two-arm randomised wait-list controlled trial of the intervention's efficacy in São Paulo, Brazil, to improve uptake of HIV testing and PrEP among transgender women (N=400). The primary outcomes are changes in HIV testing (self-testing and clinic based), changes in PrEP uptake and changes in PrEP persistence at baseline and follow-up assessment for 12 months at 3-month intervals. ETHICS AND DISSEMINATION: This study was approved by University of California, San Francisco Institutional Review Board (15-17910) and Comissão Nacional de Ética em Pesquisa (Research Ethics National Commission, CAAE: 25215219.8.0000.5479) in Brazil. Participants provided informed consent before enrolment. We are committed to collaboration with National Institutes of Health officials, other researchers, and health and social services communities for rapid dissemination of data and sharing of materials. The results will be published in peer-reviewed academic journals and scientific presentations. TRIAL REGISTRATION NUMBER: NCT03081559.

Effect of Graphene Oxide Addition on the Properties of Electrochemically Synthesized Polyaniline-Graphene Oxide Films.

In this work, the electrochemical synthesis of PANI and GO-modified PANI was performed using cyclic voltammetry, varying the amount of GO, 1 mg (PG1), 5 mg (PG5), and 10 mg (PG10) to analyze the effect of the amount of GO on the composite. PANI, PG1, PG5, and PG10 materials were characterized using optical microscopy, SEM, UV-vis, FTIR, Raman, and wettability. A stability test was also carried out by putting the materials to 500 oxidation-reduction cycles using cyclic voltammetry. The synthesis method allowed GO in PANI to be added through a chemical interaction between the two compounds. It was also found that the addition of GO led to an improvement in the hydrophilic character of the composite, which would lead to an improvement in the diffusion of reagents/species when the composites are used in aqueous media processes. The results of the stability test showed that the PG10 material presented a lower % loss of specific capacitance and energy compared with the other materials, which indicates that the GO presence (in the amount specified) improves the stability of the PANI. The PG10 material showed favorable and promising conditions for its use in fuel cell and battery processes.

Observer-based control for plasma glucose regulation in type 1 diabetes mellitus patients with unknown input delay.

This article introduces an observer-based control strategy tailored for regulating plasma glucose in type 1 diabetes mellitus patients, addressing challenges like unknown time-varying delays and meal disturbances. This control strategy is based on an extended Bergman minimal model, a nonlinear glucose-insulin model to encompass unknown inputs, such as unplanned meals, exercise disturbances, or delays. The primary contribution lies in the design of an observer-based state feedback control in the presence of unknown long delays, which seeks to support and enhance the performance of the traditional artificial pancreas by considering realistic scenarios. The observer and control gains for the observer-based control are computed through linear matrix inequalities formulated from Lyapunov conditions that guarantee closed-loop stability. This design deploys a soft and gentle dynamic response, similar to a natural pancreas, despite meal disturbances and input delays. Numerical tests demonstrate the scheme's effectiveness in glycemic level regulation and hypoglycemic episode avoidance.

Predictive Factors of Non-Inflammatory Small Bowel Obstruction After Bowel Resection in Crohn's Patients.

Background: The aim of the study was to investigate the risk factors associated with the development of small bowel obstruction (SBO) in Crohn's disease (CD) after small bowel resection (SBR) that are not due to active/recurrent inflammation. Methods: We conducted a retrospective cohort study of patients who had SBR for active or complicated CD. Abstracted data included demographics, phenotype, therapies for CD, endoscopic disease recurrence, and several surgical variables. The primary outcome was the development of non-inflammatory SBO (NI-SBO) within 5 years after SBR. Results: A total of 335 patients were included. The cumulative rates of NI-SBO at 6 months, 1 year, and 5 years were 5 (1.5%), 8 (2.4%), and 29 (8.9%), respectively. Variables associated with the development of NI-SBO were active macroscopic or microscopic inflammation in the surgical margins (13 (56%) vs. 65 (27%), P = 0.004), open resection (vs. laparoscopic resection) (12 (41.4%) vs. 60 (19.5%), P = 0.0006) and a higher median number of previous resections (2 (interquartile range (IQR) 2 - 3) vs. 1 (IQR 1 - 2), P = 0.0002). Only 21% of patients who developed NI-SBO required surgical intervention. Conclusions: The incidence of NI-SBO after SBR in CD is low and associated with inflammation at the margins of the resected bowel, previous bowel resections, and an open laparotomy approach. Most NI-SBOs resolve with medical management.

Unclassified green dots on nucleated red blood cells (nRBC) plot in DxH900 from a patient with hyperviscosity syndrome.

OBJECTIVES: Analytical interferences, caused by antibodies, often go unnoticed and require a deep understanding of analyzer principles in the correct clinical context. METHODS: A case report details a 56-year-old man with symptoms of hyperviscosity syndrome (HVS) due to multiple myeloma. RESULTS: The DxH 900 analyzer revealed abnormalities in the nucleated red blood cell (nRBC) graph, attributed to a high concentration of IgA kappa. Immediate plasmapheresis successfully treated HVS, reducing the monoclonal component and eliminating the aberrant green signal. CONCLUSIONS: In the appropriate clinical context, the recognition of analytical interferences is necessary for accurate clinical interpretation, and it is only possible with knowledge of the analytical principles of the instruments. In this case, the high concentration of IgA kappa generated an aberrant green signal in the VCSm.

Single-Cell Profiling Reveals Immune Aberrations in Progressive Idiopathic Pulmonary Fibrosis.

RATIONALE: Changes in peripheral blood cell populations have been observed but not detailed at single-cell resolution in idiopathic pulmonary fibrosis (IPF). OBJECTIVES: To provide an atlas of the changes in the peripheral immune system in stable and progressive IPF. METHODS: Peripheral blood mononuclear cells (PBMCs) from IPF patients and controls were profiled using 10x Chromium 5' single-cell RNA sequencing (scRNA-seq). Flow cytometry was used for validation. Protein concentrations of Regulatory T-cells (Tregs) and Monocytes chemoattractants were measured in plasma and lung homogenates from patients and controls. MEASUREMENTS AND MAIN RESULTS: Thirty-eight PBMC samples from 25 patients with IPF and 13 matched controls yielded 149,564 cells that segregated into 23 subpopulations. Classical monocytes were increased in progressive and stable IPF compared to controls (32.1%, 25.2%, 17.9%, respectively, p<0.05). Total lymphocytes were decreased in IPF vs controls, and in progressive vs stable IPF (52.6% vs 62.6%, p=0.035). Tregs were increased in progressive vs stable IPF (1.8% vs 1.1% of all PBMC, p=0.007), although not different than controls, and may be associated with decreased survival (P=0.009 in Kaplan-Meier analysis; P=0.069 after adjusting for age, sex, and baseline FVC). Flow cytometry analysis confirmed this finding in an independent cohort of IPF patients. Fraction of Tregs out of all T cells was also increased in two cohorts of lung scRNA-seq. CCL22 and CCL18, ligands for CCR4 and CCR8 Treg chemotaxis receptors, were increased in IPF. CONCLUSIONS: The single-cell atlas of the peripheral immune system in IPF, reveals an outcome-predictive increase in classical monocytes and Tregs, as well as evidence for a lung-blood immune recruitment axis involving CCL7 (for classical monocytes) and CCL18/CCL22 (for Tregs).

Feasibility and Short-Term Outcomes in Liver-First Approach: A Spanish Snapshot Study (the RENACI Project).

(1) Background: The liver-first approach may be indicated for colorectal cancer patients with synchronous liver metastases to whom preoperative chemotherapy opens a potential window in which liver resection may be undertaken. This study aims to present the data of feasibility and short-term outcomes in the liver-first approach. (2) Methods: A prospective observational study was performed in Spanish hospitals that had a medium/high-volume of HPB surgeries from 1 June 2019 to 31 August 2020. (3) Results: In total, 40 hospitals participated, including a total of 2288 hepatectomies, 1350 for colorectal liver metastases, 150 of them (11.1%) using the liver-first approach, 63 (42.0%) in hospitals performing <50 hepatectomies/year. The proportion of patients as ASA III was significantly higher in centers performing ≥50 hepatectomies/year (difference: 18.9%; p = 0.0213). In 81.1% of the cases, the primary tumor was in the rectum or sigmoid colon. In total, 40% of the patients underwent major hepatectomies. The surgical approach was open surgery in 87 (58.0%) patients. Resection margins were R0 in 78.5% of the patients. In total, 40 (26.7%) patients had complications after the liver resection and 36 (27.3%) had complications after the primary resection. One-hundred and thirty-two (89.3%) patients completed the therapeutic regime. (4) Conclusions: There were no differences in the surgical outcomes between the centers performing <50 and ≥50 hepatectomies/year. Further analysis evaluating factors associated with clinical outcomes and determining the best candidates for this approach will be subsequently conducted.

Infraspecific Variation in Silene Seed Tubercles.

The seeds of many species in the order Caryophyllales exhibit surface protuberances called tubercles. While tubercle shape and distribution have often been proposed as taxonomic criteria, paradoxically, their description has primarily relied on adjectives, with quantitative data on tubercle width, height, and other measurements lacking in the literature. Recently, a quantitative analysis of seed surface tubercles based on tubercle width, height, and curvature values (maximum and average curvature, and maximum to average curvature ratio) was proposed and applied to individual populations of a total of 31 species, with 12 belonging to Silene subg. Behenantha and 19 to S. subg. Silene. Tubercles were classified into two categories: echinate and rugose. Echinate tubercles exhibited higher values of height and curvature, and lower width, and were more prevalent in species of S. subg. Behenantha, while the rugose type was more abundant in S. subg. Silene. This work explored infraspecific differences in tubercle size and shape. For this, measurements of tubercle width, height and curvature were applied to 31 populations of eight species of Silene. Significant differences between populations were observed for most of the species examined. A particular tubercle type, previously described as umbonate or mammillate, was identified in S. nocturna seeds, characterized by high curvature values.
