Characteristics, outcomes and treatment patterns in acute myeloid leukemia patients 60 years or older in Colombia: a RENEHOC-PETHEMA study.

There is a limited information available on the clinical characteristics, treatment patterns and outcomes on older patients diagnosed with Acute Myeloid Leukemia (AML) in Latin-America. This multicenter retrospective study analyzed 269 patients over 60 years of age diagnosed with AML in Colombia, using data from RENEHOC-PETHEMA registry, from 2009 to 2023. The median age at diagnosis was 70 years (Range:60-98), 55% were men, 61% had an ECOG < 2, and 75.

Validation of the Contraception-Focused Preference-Aligned Fertility Management Index in Uganda and Nigeria.

Objective: To evaluate construct validity of the contraception-focused "Preference-aligned Fertility Management" (PFM) Index, a new person-centered and rights-based outcome measure, in Nigeria and Uganda.

Study Design: We analyzed survey data from convenience samples of new users of contraception and non-users of contraception in Uganda and users of contraception in Nigeria. PFM Index scores were calculated by combining two indicators: Indicator 1 assessing alignment between desire to use contraception and actual use; Indicator 2 evaluating whether users' current methods are desired.

Segmental Odontomaxillary Dysplasia: Unusual Tumoral Lesion.

Introduction: Segmental Odontomaxillary Dysplasia (SOD) is a non-hereditary, unilateral developmental anomaly recently included in the WHO's classification of head and neck tumors.

Case Presentation: Here, we report the case of an 8-year-old boy presenting with unilateral maxillary enlargement and pain without facial asymmetry. Computed tomography revealed a hypodense area in the maxillary bone with altered bone structure and osseous expansion.

Bisphenol A and Its Emergent Substitutes: State of the Art of the Impact of These Plasticizers on Oxidative Stress and Its Role in Vascular Dysfunction.

The "One Health approach" has evidenced the significant impact of xenobiotic exposure to health, and humans are a relevant target for their toxic effects. Bisphenol A (BPA) exerts a ubiquitous exposure source in all ecosystems. Given its endocrine-disrupting and harmful consequences on health, several countries have enforced new regulations to reduce exposure to BPA.

Angiotensin II elicits robust calcium oscillations coordinated within juxtaglomerular cell clusters to suppress renin secretion.

Background: Juxtaglomerular (JG) cells are sensors that control blood pressure and fluid-electrolyte homeostasis. In response to a decrease in perfusion pressure or changes in the composition and/or volume of the extracellular fluid, JG cells release renin, which initiates an enzymatic cascade that culminates in the production of angiotensin II (Ang II), a potent vasoconstrictor that restores blood pressure and fluid homeostasis. In turn, Ang II exerts a negative feedback on renin release, thus preventing excess circulating renin and the development of hypertension.

Chronic spontaneous urticaria remission definition and therapy stepping down: World Allergy Organization position paper.

Background: There is no global agreement on the definition of chronic spontaneous urticaria (CSU) remission.

Objective: Our aim was to generate a consensus for clinical definitions of CSU-related terms focused on remission.

Methods: The World Allergy Organization Urticaria Committee systematically reviewed current available longitudinal articles.

Incremental Validity of ADHD Dimensions in the Predictions of Emotional Symptoms, Conduct Problems, and Peer Problems in Adolescents Based on Parent, Teacher, and Self-Ratings.

The present study investigated the incremental validity of the ADHD dimensions of inattention (IA), hyperactivity (HY), and impulsivity (IM) in the predictions of emotion symptoms (ESs), conduct problems (CPs), and peer problems (PPs) in adolescents based on parent, teacher, and self- ratings. A total of 214 ratings were collected from adolescents, their parents, and teachers in Australia. A structural equation modeling approach was employed to evaluated incremental validity.

A Re-Evaluation of the Utility of Symptom Checklist-90-Revised for Measuring the Spectra in the Hierarchical Taxonomy of Psychopathology.

Unlabelled: The present study examines the potential of the Symptom Checklist-90-Revised (SCL-90-R) as a measure for the Hierarchical Taxonomy of Psychopathology (HiTop) model. Two structural models were evaluated. In Model 1, the SCL-90-R dimensions were allocated to somatoform (comprising somatization), internalizing (comprising obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and phobic anxiety), and antagonistic disinhibited (comprising hostility) spectra.

Association of Menopause With Functional Outcomes and Disease Biomarkers in Women With Multiple Sclerosis.

Background And Objective: The impact of menopause on the brain is not well understood. Hormonal changes, including puberty and pregnancy, influence the onset and course of multiple sclerosis (MS). After menopause, a worsening of MS disease trajectory measured on the clinician-rated Expanded Disability Status Scale (EDSS) was reported in some, but not all, studies.

Magnetic Effects in Electrocatalysis Studied with Electrochemical Impedance Spectroscopy: The Cases of Oxygen Reduction and Evolution Reactions on Cobalt Ferrite Electrodes.

Recent years have witnessed an intense effort to unravel magnetic field effects in electrocatalysis, as they can enhance the performance of common electrocatalysts. Both experimental and theoretical studies have shown that magnetic fields may affect, among others, the macroscopic spin-orbital ordering, charge transport, bubble release, and electron transfer kinetics. This paper highlights Electrochemical Impedance Spectroscopy (EIS) as a tool to analyze and separate the effects of magnetic field on both the oxygen reduction and evolution reactions at cobalt iron oxide electrodes.

Beyond Connectivity: Exploring the Influence of Digital Access on the Social Determinants of Health for Youth in Out-of-Home Care.

This study explores digital inclusion for youth in out-of-home placement within the child welfare system, a group impacted by significant social determinants affecting health. Recognized as a "super social determinant of health," digital inclusion holds promise in addressing key health factors, such as social relationships, support systems, and information access. The study surveyed 131 foster parents and 152 kinship providers across varied U.

Using Network Analysis of Adolescent Self-Ratings of ADHD Symptoms to Identify Central Symptoms and Their Associations With Each Other and Global Functioning.

This research examined the network properties (network graph, centrality, and edge weights) of the 18 ADHD symptoms, based on the self-ratings of 300 adolescents. The findings indicated the three symptoms with the highest centrality values were "inattention", "wait", and "interrupt". For edge weights, there were positive large effect size associations for "lose" with "forgetful", "fidget with "run", "blurt" with "wait", and "wait" with "interrupt"; and positive moderate effect size associations for "careless" with "instruction", and "avoid" with "listen".

Impaired maternal central hemodynamics precede the onset of vascular disorders of pregnancy at high altitude.

Hypertensive disorders of pregnancy represent an escalating global health concern with increasing incidence in low- to middle-income countries and high-income countries alike. The current lack of methods to detect the subclinical stages of preeclampsia (PE) and fetal growth restriction (FGR), two common vascular disorders of pregnancy, limits treatment options to minimize acute- and long-term adverse outcomes for both mother and child. To determine whether impaired maternal cardiovascular or uteroplacental vascular function precedes the onset of PE and/or FGR (PE-FGR), we used noninvasive techniques to obtain serial measurements of maternal cardiac output (CO), stroke volume (SV), systemic vascular resistance (SVR), and uterine and fetal arterial resistance at , -, and for 79 maternal-infant pairs in La Paz-El Alto, Bolivia (3,850 m), where the chronic hypoxia of high altitude increases the incidence of PE and FGR.

Mechanical problem solving by plush-crested jays: are tools special after all?

Tool use is taxonomically associated with high behavioural flexibility and innovativeness, and its prevalence is greater in primates and some bird species. This association, however, is not known to be causally determinant of tool-related competence since flexibility and innovativeness are often observed in the absence of tool use and vice versa. For this reason, it is interesting to explore whether animals that can be loosely categorized as outstanding, or 'intelligent' physical problem solvers, are also remarkable using tools innovatively, rather than tool use presenting special constraints.

A PCR-Based Approach for Early Diagnosis of Head and Neck Aspergillosis: A Pilot Study.

Background: Aspergillosis is a fungal disease caused by the inhalation of fungal spores of the genus spp. This fungus mainly affects the lungs but can spread and infect the maxillofacial region through the bloodstream or inoculation of the fungus after extraction or endodontic treatment, especially in the upper posterior teeth. The disease has nonspecific clinical manifestations that hinder its early diagnosis.

Tcf21 as a founder transcription factor in specifying Foxd1 cells to the juxtaglomerular cell lineage.

Renin is crucial for blood pressure regulation and electrolyte balance, and its expressing cells arise from Forkhead box D1-positive (Foxd1) stromal progenitors. However, factors guiding these progenitors toward renin-secreting cell fate remain unclear. Tcf21, a basic helix-loop-helix (bHLH) transcription factor, is essential in kidney development.

Global change, climate change, and asthma in children: Direct and indirect effects - A WAO Pediatric Asthma Committee Report.

The twenty-first century has seen a fundamental shift in disease epidemiology with anthropogenic environmental change emerging as the likely dominant factor affecting the distribution and severity of current and future human disease. This is especially true of allergic diseases and asthma with their intimate relationship with the natural environment. Climate change-related variables including increased ambient temperature, heat waves, extreme weather events, air pollution, and rainfall distribution, all can affect asthma in children, but each of these variables also affects asthma via alterations in pollen production and release, outdoor allergen exposure or the microbiome.

Genomics of a sexually selected sperm ornament and female preference in Drosophila.

Our understanding of animal ornaments and the mating preferences driving their exaggeration is limited by knowledge of their genetics. Post-copulatory sexual selection is credited with the rapid evolution of female sperm-storage organ morphology and corresponding sperm quality traits across diverse taxa. In Drosophila, the mechanisms by which longer flagella convey an advantage in the competition among sperm for limited storage space in the female, and by which female sperm-storage organ morphology biases fertilization in favour of longer sperm have been resolved.

Machine Learning(s) in gaming disorder through the user-avatar bond: A step towards conceptual and methodological clarity.

In response to our study, the commentary by Infanti et al. (2024) raised critical points regarding (i) the conceptualization and utility of the user-avatar bond in addressing gaming disorder (GD) risk, and (ii) the optimization of supervised machine learning techniques applied to assess GD risk. To advance the scientific dialogue and progress in these areas, the present paper aims to: (i) enhance the clarity and understanding of the concepts of the avatar, the user-avatar bond, and the digital phenotype concerning gaming disorder (GD) within the broader field of behavioral addictions, and (ii) comparatively assess how the user-avatar bond (UAB) may predict GD risk, by both removing data augmentation before the data split and by implementing alternative data imbalance treatment approaches in programming.

HLA-G high-expressor 3'UTR markers are linked to gastric cancer development and survival.

Gastric cancer ranks fifth in both world prevalence and lethality, with a 5-year survival of less than 30%. HLA-G, a non-classical class I HLA gene, has emerged as a potential marker for cancer susceptibility and prognosis due to its immunomodulatory properties. Its level of expression is regulated by polymorphisms in the 3' untranslated region (3'UTR) polymorphisms, which form various combined haplotypes (UTR-1 to -9).
