RESUMEN

Overactivation of the JAK/STAT pathway is one of the drivers for the pathophysiology of hepatocellular carcinoma (HCC). We propose a Phase Ib study to evaluate the safety and efficacy of itacitinib, a selective JAK1 inhibitor, as a second-line treatment for patients with advanced or metastatic HCC.Twenty-five patients will receive 400 mg itacitinib orally daily, 28-day cycle. Safety will be reviewed prior to each cycle. Tumor response assessed every 2 months until disease progression, death or withdrawal. Tumor biopsies and blood samples will be taken for presence of JAK1 mutations.Activation of JAK/STAT pathway drives HCC development and is associated with immunotherapy resistance. Itacitinib is hypothesized to be safe and effective in HCC patients that have progressed after first-line therapies.Clinical Trial Registration: EudraCT: 2017-004437-81 NCT04358185 (ClinicalTrials.gov).

RESUMEN

The oviduct and uterus provide an optimal environment for early embryo development, where effective communication between the embryo and the maternal reproductive tract is crucial for establishing and maintaining pregnancy. Oviductal and uterine-derived EVs play pivotal roles in this maternal-embryonic communication and in facilitating early embryo development. However, despite the ability of in vitro culture methods to produce viable embryos, the lack of exchange between the embryo and the mother often results in lower-quality embryos than those derived in vivo. Therefore, there is a pressing need to increase our understanding of the physiological mechanisms underlying embryo interaction with the oviduct and endometrium through EVs and to develop models capable of mimicking the in vivo environment. This review aims to provide up-to-date insights into the communication between the mother and pre-implantation bovine embryo, exploring their applications and perspectives in the field.

RESUMEN

Introduction: Numerous studies have found that exposure to violence at home is a risk factor for child-to-parent violence. However, most of the available studies do not delimit a time frame for exposure to violence. This aspect is fundamental to differentiating lagged effects (compensation) from simultaneous effects (reciprocal). The purpose of this study is to clarify the relationship between lagged (before the age of 10) and simultaneous (last year) exposure to violence at home (direct victimization: parent-to-child violence and vicarious victimization: exposure to violence between parents) and child-to-parent violence, the possible differential reactive or instrumental motivation of these relationships and whether they differ based on the gender of children and parents. Method: The sample comprised 1,734 Spanish adolescents who lived with both parents (57.3% girls), aged between 13 and 17 years. The instruments used were the Child-to-Parent Violence Questionnaire and the Violence Exposure Scale. Results: Positive and significant relationships were found between child-to-parent violence and exposure to violence at home both during childhood and during the last year; however, the relationships were stronger in the latter. The most important predictors were direct parental victimization during the last year. Boys exerted more reactive violence toward the father concerning exposure to violence by the father toward the mother during the last year. In the case of girls, violence toward both father and mother is more reactive to most victimization experiences. Conclusions: The findings highlight the need to intervene in family contexts of violence to prevent child-to-parent violence.

RESUMEN

The growth and development of green lettuce plants can be modulated by the prevailing light conditions around them. The aim of this study was to evaluate the effect of ambient light enrichment with different LED light spectra on agronomic characteristics, polyphenol concentration and relative gene expression of enzymes associated with polyphenol formation in 'Levistro' lettuce grown hydroponically in a Nutrient Film Technique (NFT) system for 28 days in a greenhouse. The spectra (blue:green:red:far-red) and red:blue (R:B) ratios obtained by enriching ambient light with Blue (B), White (W), Blue-Red (BR) and Red (R) LED light were B: 47:22:21:10, 0.5:1; W: 30:38:23:9, 0.8:1; BR: 33:15:44:8, 1.3:1 and R: 16:16:60:8, 3.8:1, respectively, and photosynthetically active radiation (PAR) under the different treatments, measured at midday, ranged from 328 to 336 µmoles m-2 s-1. The resulting daily light integral (DLI) was between 9.1 and 9.6 mol m-2 day-1. The photoperiod for all enrichment treatments was 12 h of light. The control was ambient greenhouse light (25:30:30:15; R:B = 1.2:1; PAR = 702 µmoles m-2 s-1; DLI = 16.9 mol m-2 day-1; photoperiod = 14.2 h of light). Fresh weight (FW) and dried weight percentage (DWP) were similar among the enrichment treatments and the control. The leaf number increased significantly under BR and R compared to B lights. The relative index of chlorophyll concentration (RIC) increased as plants grew and was similar among the enrichment treatments and the control. On the other hand, the concentration of chlorogenic acid and chicoric acid increased under BR and B lights, which was consistent with the higher relative expression of the coumarate 3-hydroxylase enzyme gene. In view of the results, it is inferred that half of the PAR or DLI is sufficient to achieve normal growth and development of 'Levistro' lettuce plants, suggesting a more efficient use of light energy under the light enrichment treatments. On the other hand, the blue and combined blue-red lights promoted the accumulation of phenolic compounds in the leaves of 'Levistro' lettuce plants.

RESUMEN

A new family of monothiooxalamides derived from 2-aminobenzimidazole was synthesized, and their structures were confirmed by 1H and 13C one-dimensional and 2D NMR experiments (COSY, HSQC, and HMBC). The antioxidant capacity was evaluated by free radical scavenging assays: 1,1-diphenyl-2-picrylhydrazyl (DPPH•), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS•+), ferric reducing antioxidant power (FRAP), oxygen radical absorbance capacity (ORAC), and the Fe(II) chelating ability. Our work group has previously reported the synthesis and antioxidant activity of monothiooxalamides derived from 2-aminopyridine (I). In this study, the in vitro hemolytic activity of compounds from the 2-aminopyridine (I) and 2-aminobenzimidazole (II) families was evaluated against human red blood cells (RBCs). The concentration at which monothiooxalamides showed no hemolytic activity was chosen to assess their ability to inhibit free radical-induced membrane damage in human RBCs, acute toxicity in brine shrimp, and in vivo toxicity against Drosophila melanogaster. Compounds with morpholine fragments (1g, 1h, 2g, and 2h) showed time- and concentration-dependent protective effects against radical-induced oxidative hemolysis. Moreover, they had the lowest acute toxicity in the brine shrimp lethality assay and a significant increase in chelating activity compared with the other molecules. In particular, monothiooxalamide 2g showed lower toxicity and can be considered for further biological screening and application trials.

RESUMEN

BACKGROUND: The International Labour Organization (ILO) and the United Nations (UN) have promoted the concept of decent work as a Sustainable Development Goal for 2030 to address critical global problems. Occupational safety and health (OSH) are components of decent work, primarily through the ILO social protection objective of the goal, and are linked to various other objectives. OBJECTIVE: This Commentary applies a previously published staging framework to stimulate thinking about how the OSH field can contribute further to the achievement of decent work. METHODS: To advance the contribution of the framework, the different functions of OSH (research, practice, advocacy, governance, and professional education) were used to identify impediments to achieving decent work and develop recommendations for each determinant in the framework. RESULTS: Promoting and achieving decent work are complex issues that require a multifactorial approach. Numerous recommendations supporting systems thinking and transdisciplinary approaches are provided. CONCLUSIONS: The OSH field can expand to further address decent work.

RESUMEN

Busulfan (Bu) is an important component of many conditioning regimens for allogeneic hematopoietic cell transplantation. The therapeutic window of Bu is well characterized, with strong associations between Bu exposure and the clinical outcome in adults (strongest evidence in myelo-ablative setting) and children (all settings). We provide an overview of the literature on Bu as well as a step-by-step guide to the implementation of Bu therapeutic drug monitoring (TDM). The guide covers the clinical, pharmacological, laboratory and administrative aspects of the procedure. Through this document, we aim to support centers in implementing TDM for Bu to further enhance the success rates of HCT and improve patient outcomes. The Pharmacist Committee of the European Society for Blood and Marrow Transplantation (EBMT) encourages all centers to perform TDM for Bu in the aforementioned indications.

RESUMEN

The macrolide drug rapamycin is a benchmark anti-ageing drug, which robustly extends lifespan of diverse organisms. For any health intervention, it is paramount to establish whether benefits are distributed equitably among individuals and populations, and ideally to match intervention to recipients' needs. However, how responses to rapamycin vary is surprisingly understudied. Here we investigate how among-population variation in both mitochondrial and nuclear genetics shapes rapamycin's effects on lifespan. We show that epistatic "mito-nuclear" interactions, between mitochondria and nuclei, modulate the response to rapamycin treatment. Differences manifest as differential demographic effects of rapamycin, with altered age-specific mortality rate. However, a fitness cost of rapamycin early in life does not show a correlated response, suggesting that mito-nuclear epistasis can decouple costs and benefits of treatment. These findings suggest that a deeper understanding of how variation in mitochondrial and nuclear genomes shapes physiology may facilitate tailoring of anti-ageing therapy to individual need.

RESUMEN

BACKGROUND: Two-thirds of patients with immunoglobulin light chain (AL) amyloidosis have renal involvement. The biochemical profile of kidney damage is poorly described. METHODS: A cross-sectional study was conducted involving patients diagnosed with AL amyloidosis and renal involvement between January 1, 2010, and April 30, 2022 at the Hospital Italiano de Buenos Aires. Participants were retrospectively identified from the Institutional Amyloidosis Registry. Patients diagnosed with AL amyloidosis and evidence of renal involvement were included. Individuals with other types of amyloidosis were excluded. The selection process involved a thorough review of medical records and registry data to ensure accurate identification and inclusion of eligible participants. RESULTS: Seventy-seven patients were included. At diagnosis, 90% of the subjects had proteinuria, with a median of 4.3 g/24 h, 61% had renal failure, and 47% presented nephrotic syndrome. Semi-automated urinary electrophoresis revealed 55% with non-selective and 21% with moderately selective glomerular proteinuria. Urine immunofixation indicated 64% with lambda monoclonal free light chains and 12% with kappa. Serum immunofixation demonstrated 48% with lambda monoclonal type and 25% with lambda IgG. At the time of diagnosis of AL amyloidosis, the median age was 66 years (IQR 53-72) and 49% were men. In addition to kidney involvement, other organs were also affected: heart in 53%, gastrointestinal system in 19%, peripheral nervous system in 16%, and liver in 16% of patients. CONCLUSION: Our study provides a biochemical profile in renal amyloidosis due to immunoglobulin light chains in a Latin American population. Proteinuria emerged as the most common finding in this cohort with frequent multiorgan involvement.

RESUMEN

Lignocellulosic biomass, the most abundant natural resource on earth, can be used for cellulosic ethanol production but requires a pretreatment to improve enzyme access to the polymeric sugars while obtaining value from the other components. γ-Valerolactone (GVL) is a promising candidate for biomass pretreatment since it is renewable and bio-based. In the present work, the effect of a pretreatment based on GVL on the enzymatic saccharification of white birch was evaluated at a laboratory scale and the importance of the washing procedure for the subsequent saccharification was demonstrated. Both the saccharification yield and the production of cellulosic ethanol were higher using a noncommercial enzyme crude from Talaromyces amestolkiae than with the commercial cocktail Cellic CTec2 from Novozymes. Furthermore, the production of extracellular cellulases by T. amestolkiae has been optimized in 2 L bioreactors, with improvements ranging from 40% to 75%. Finally, it was corroborated by isoelectric focus that optimization of cellulase secretion by T. amestolkiae did not affect the pattern production of the main ß-glucosidases and endoglucanases secreted by this fungus.

RESUMEN

BACKGROUND: Risk scores facilitate the assessment of mortality risk in patients with community-acquired pneumonia (CAP). Despite their utilities, there is a scarcity of evidence comparing the various RS simultaneously. This study aims to evaluate and compare multiple risk scores reported in the literature for predicting 30-day mortality in adult patients with CAP. METHODS: A retrospective cohort study on patients diagnosed with CAP was conducted across two hospitals in Colombia. The areas under receiver operating characteristic curves (ROC-curves) were calculated for the outcome of survival or death at 30 days using the scores obtained for each of the analyzed questionnaires. RESULTS: A total of 7454 potentially eligible patients were included, with 4350 in the final analysis, of whom 15.2% (662/4350) died within 30 days. The average age was 65.4 years (SD: 21.31), and 59.5% (2563/4350) were male. Chronic kidney disease was 3.7% (9.2% vs. 5.5%; p < 0.001) (OR: 1.85) higher in subjects who died compared to those who survived. Among the patients who died, 33.2% (220/662) presented septic shock compared to 7.3% (271/3688) of the patients who survived (p < 0.001). The best performances at 30 days were shown by the following scores: PSI, SMART-COP and CURB 65 scores with the areas under ROC-curves of 0.83 (95% CI: 0.8-0.85), 0.75 (95% CI: 0.66-0.83), and 0.73 (95% CI: 0.71-0.76), respectively. The RS with the lowest performance was SIRS with the area under ROC-curve of 0.53 (95% CI: 0.51-0.56). CONCLUSION: The PSI, SMART-COP and CURB 65, demonstrated the best diagnostic performances for predicting 30-day mortality in patients diagnosed with CAP. The burden of comorbidities and complications associated with CAP was higher in patients who died.

RESUMEN

BACKGROUND: Depression is a chronic psychiatric disease of multifactorial etiology, and its pathophysiology is not fully understood. Stress and other chronic inflammatory pathologies are shared risk factors for psychiatric diseases, and comorbidities are features of major depression. Epidemiological evidence suggests that periodontitis, as a source of low-grade chronic systemic inflammation, may be associated with depression, but the underlying mechanisms are not well understood. METHODS: Periodontitis (P) was induced in Wistar: Han rats through oral gavage with the pathogenic bacteria Porphyromonas gingivalis and Fusobacterium nucleatum for 12 weeks, followed by 3 weeks of chronic mild stress (CMS) to induce depressive-like behavior. The following four groups were established (n = 12 rats/group): periodontitis and CMS (P + CMS+), periodontitis without CMS, CMS without periodontitis, and control. The morphology and inflammatory phenotype of microglia in the frontal cortex (FC) were studied using immunofluorescence and bioinformatics tools. The endocannabinoid (EC) signaling and proteins related to synaptic plasticity were analyzed in FC samples using biochemical and immunohistochemical techniques. RESULTS: Ultrastructural and fractal analyses of FC revealed a significant increase in the complexity and heterogeneity of Iba1 + parenchymal microglia in the combined experimental model (P + CMS+) and increased expression of the proinflammatory marker inducible nitric oxide synthase (iNOS), while there were no changes in the expression of cannabinoid receptor 2 (CB2). In the FC protein extracts of the P + CMS + animals, there was a decrease in the levels of the EC metabolic enzymes N-acyl phosphatidylethanolamine-specific phospholipase D (NAPE-PLD), diacylglycerol lipase (DAGL), and monoacylglycerol lipase (MAGL) compared to those in the controls, which extended to protein expression in neurons and in FC extracts of cannabinoid receptor 1 (CB1) and to the intracellular signaling molecules phosphatidylinositol-3-kinase (PI3K), protein kinase B (Akt) and extracellular signal-regulated kinase 1/2 (ERK1/2). The protein levels of brain-derived neurotrophic factor (BDNF) and synaptophysin were also lower in P + CMS + animals than in controls. CONCLUSIONS: The combined effects on microglial morphology and inflammatory phenotype, the EC signaling, and proteins related to synaptic plasticity in P + CMS + animals may represent relevant mechanisms explaining the association between periodontitis and depression. These findings highlight potential therapeutic targets that warrant further investigation.

RESUMEN

BACKGROUND: Breast cancer has been associated with monogenic, polygenic, and epidemiologic (clinical, reproductive and lifestyle) risk factors, but studies evaluating the combined effects of these factors have been limited. METHODS: We extended previous work in breast cancer risk modeling, incorporating pathogenic variants (PV) in six breast cancer predisposition genes and a 105-SNP polygenic risk score (PRS), to include an epidemiologic risk score (ERS) in a sample of non-Hispanic White women drawn from prospective cohorts and population-based case-control studies, with 23,518 cases and 22,832 controls, from the Cancer Risk Estimates Related to Susceptibility (CARRIERS) Consortium. RESULTS: The model predicts 4.4-fold higher risk of breast cancer for postmenopausal women with no predisposition PV and median PRS, but with the highest versus lowest ERS. Overall, women with CHEK2 PVs had >20% lifetime risk of breast cancer. However, 15.6% of women with CHEK2 PVs and a family history of breast cancer, and 45.1% of women with CHEK2 PVs but without a family history of breast cancer, had low (<20%) predicted lifetime risk and thus were below the threshold for MRI screening. CHEK2 PV carriers at the 10th percentile of the joint distribution of ERS and PRS, without a family history of breast cancer, had a predicted lifetime risk similar to the general population. CONCLUSIONS: These results illustrate that an ERS, alone and combined with the PRS, can contribute to clinically relevant risk stratification. IMPACT: Integrating monogenic, polygenic, and epidemiologic risk factors in breast cancer risk prediction models may inform personalized screening and prevention efforts.

RESUMEN

AIMS: Periodontitis and cardiovascular diseases (CVD) are highly prevalent non-communicable diseases, sharing an inflammatory pathogenesis and common risk factors. The objective of the present research is to assess the association between periodontitis and cardiovascular disease risk in a representative sample of the Spanish-employed population. METHODS: Cross-sectional data were obtained between 2008 and 2011 in the Workers' Oral Health (WORALTH) epidemiological study. Periodontal examinations were based on the evaluation of clinical attachment loss (CAL) and community periodontal index (CPI). Participants also underwent a medical check-up and answered a comprehensive health questionnaire. With this information, participants were categorized into three levels of CVD risk using the systemic coronary risk estimation (SCORE) algorithm for low-risk European countries. Crude and adjusted odds ratios (ORs) were determined with multiple logistic regression models for the association between periodontal status and CVD risk. RESULTS: Data from 4224 individuals were analyzed. The overall prevalence of high CVD risk (SCORE ≥ 5%) was 5.1%. The prevalence of SCORE ≥ 5% was 3.4%, 9.4%, and 15.2% for CAL 0-3 mm, 4-5 mm, and ≥6 mm, respectively (p < .001), and 6.2%, 6.5%, and 14.6% for CPI ≤2, 3, and 4, respectively (p < .001). Individuals with CPI = 4 presented an OR of 1.50 (95% confidence interval, CI [1.04; 2.17]) for high SCORE values, after adjusting for confounders (age, sex, and smoking habit). CONCLUSIONS: Periodontitis, defined by the presence of deep periodontal pockets (≥6 mm), was significantly associated with high CVD risk (SCORE ≥ 5%) in a representative sample of the employed population in Spain.

RESUMEN

Rheumatoid arthritis (RA) is a common autoimmune and inflammatory disease characterized by inflammation and hyperplasia of the synovial tissues. RA pathogenesis involves multiple cell types, genes, transcription factors (TFs) and networks. Yet, little is known about the TFs, and key drivers and networks regulating cell function and disease at the synovial tissue level, which is the site of disease. In the present study, we used available RNA-seq databases generated from synovial tissues and developed a novel approach to elucidate cell type-specific regulatory networks on synovial tissue genes in RA. We leverage established computational methodologies to infer sample-specific gene regulatory networks and applied statistical methods to compare network properties across phenotypic groups (RA versus osteoarthritis). We developed computational approaches to rank TFs based on their contribution to the observed phenotypic differences between RA and controls across different cell types. We identified 18 (fibroblast-like synoviocyte), 16 (T cells), 19 (B cells) and 11 (monocyte) key regulators in RA synovial tissues. Interestingly, fibroblast-like synoviocyte (FLS) and B cells were driven by multiple independent co-regulatory TF clusters that included MITF, HLX, BACH1 (FLS) and KLF13, FOSB, FOSL1 (B cells). However, monocytes were collectively governed by a single cluster of TF drivers, responsible for the main phenotypic differences between RA and controls, which included RFX5, IRF9, CREB5. Among several cell subset and pathway changes, we also detected reduced presence of Natural killer T (NKT) cells and eosinophils in RA synovial tissues. Overall, our novel approach identified new and previously unsuspected Key driver genes (KDG), TF and networks and should help better understanding individual cell regulation and co-regulatory networks in RA pathogenesis, as well as potentially generate new targets for treatment.

RESUMEN

Human African trypanosomiasis is among the World Health Organization's designated neglected tropical diseases. Repurposing strategies are often employed in academic drug discovery programs due to financial limitations, and in this instance, we used human kinase inhibitor chemotypes to identify substituted 4-aminoazaindoles, exemplified by 1. Structure-activity and structure-property relationship analysis, informed by cheminformatics, identified 4s as a potent inhibitor of Trypanosoma brucei growth. While 4s appeared to be fast acting and cidal in the in vitro assays, it failed to cure a murine model of infection. Preliminary efforts to identify the potential mechanism of action of the series pointed to arginine kinase, though, as we demonstrate, this does not appear to be the sole target of our compounds. This comprehensive approach to drug discovery, encompassing cheminformatics, structure-potency and structure-property analysis, and pharmacophore identification, highlights our multipronged efforts to identify novel lead compounds for this deadly disease.

RESUMEN

INTRODUCTION: This study aimed to describe the reported prevalence of post-COVID-19 syndrome and its characteristics by gender, profession, and other determinants among health care workers. METHODS: A cross-sectional study was conducted among health workers with a history of COVID-19 in Latin America, and the 2030 responses from Argentina were selected for this analysis. Sociodemographic information, as well as data on initial course of COVID-19, and the persistence of 21 symptoms beyond the first month, their severity, clinical evolution, and health care demands were collected. RESULTS: The reported prevalence of post-COVID-19 syndrome was higher in women for each of the symptom clusters studied. Severity of the initial symptoms, female gender, nursing profession, multi-employment, and working in emergency areas were all independent variables. DISCUSSION: The greater strain of health care workers during the pandemic -highly feminized- and the associated gender conditions may partially explain these findings.


Introducción: El objetivo del estudio fue describir la prevalencia del reporte de síndrome post-COVID-19 y sus características según género, profesión y otros determinantes sociales, en personal de salud. Métodos: Se realizó un estudio de corte transversal en profesionales de salud con antecedentes de COVID-19 en América Latina, y para este análisis se seleccionaron las 2030 respuestas de Argentina. Se recolectaron datos sociodemográficos, información sobre el curso inicial de la enfermedad COVID-19, y persistencia de 21 síntomas más allá del primer mes, su gravedad, evolución clínica y requerimiento de servicios de salud. Resultados: Se identificó que la prevalencia reportada de síndrome post-COVID-19 fue mayor en mujeres para cada uno de los grupos de síntomas explorados. La gravedad del cuadro inicial, el género femenino, la profesión de enfermería, el multiempleo y trabajar en áreas de emergencia fueron variables independientes. Discusión: La mayor sobrecarga del personal de salud durante la pandemia ­altamente feminizado­ y las determinaciones de género asociadas podrían explicar parcialmente estos hallazgos.

RESUMEN

Hemiplegic migraine consists of attacks of migraine with aura that includes reversible motor weakness. It is classified as familial or sporadic depending on the involvement or not of a first or second degree relative. The most described subtypes of familial hemiplegic migraine include FHM1, FHM2, and FHM3. These have been demonstrated to have a mutation in either CACNA1A, ATP1A2 or SCN1A, which encode different subunits of channels, involving P/Q-type calcium channel, Na/K pump and Na channel, respectively, located in neurons and glial cells. Mutations localized in different genes are defined as "other loci." Patients with a known mutation can have different genetic penetrance, and may present a more complex and disabling phenotype that develops earlier in life. The clinical manifestations can be similar in the three mutations, including neurologic comorbidities other than muscular weakness, such as episodes of loss of consciousness, epilepsy, gait or limb ataxia or movement disorders, among others. Treatment includes antiepileptics such as lamotrigine, valproate or topiramate, calcium blockers such as flunarizine or verapamil and acetazolamide.
