C-reactive Protein and Risk of Right Ventricular Dysfunction and Mortality in Patients With Acute Symptomatic Pulmonary Embolism.

BACKGROUND: Right ventricle (RV) dysfunction increases the risk of death from pulmonary embolism (PE). C-reactive protein (CRP) might identify RV inflammation and dysfunction in patients with PE. METHODS: This cohort study enrolled consecutive stable patients with acute PE between 2017 and 2023. We stratified patients by quartiles of CRP. We evaluated the association between CRP quartiles and the presence of RV dysfunction, and used multivariable models to assess for an association between CRP and the outcomes of all-cause and PE-specific mortality during the 30 days of follow-up after PE diagnosis. RESULTS: The study included 633 stable patients with PE. Patients without RV dysfunction had significantly lower median (IQR) CRP levels compared with patients with RV dysfunction (n=509, 31.7 [10.0-76.4]mg/L vs n=124, 45.4 [16.0-111.4]mg/L; P=0.018). CRP showed a statistically significant positive association with the presence of RV dysfunction (P<0.01). On multivariable analysis, CRP level was not significantly associated with 30-day all-cause mortality (adjusted odds ratio [OR] per mg/L increment, 1.00; 95% CI, 1.00-1.01; P=0.095), but higher CRP was associated with significantly higher PE-related mortality (adjusted OR, 1.01; 95% CI, 1.00-1.01; P=0.026). Compared with patients in CRP quartile 1, patients in quartiles 2, 3, and 4 had a stepwise increase in the adjusted odds of 30-day all-cause death of 2.41 (P=0.148), 3.04 (P=0.062), and 3.15 (P=0.052), respectively. CONCLUSIONS: As an indicator of RV dysfunction, CRP may improve risk stratification algorithms for hemodynamically stable patients with acute symptomatic PE.

Screening mammography frequency following dense breast notification among a predominantly Hispanic/Latina screening cohort.

PURPOSE: Nationally legislated dense breast notification (DBN) informs women of their breast density (BD) and the impact of BD on breast cancer risk and detection, but consequences for screening participation are unclear. We evaluated the association of DBN in New York State (NYS) with subsequent screening mammography in a largely Hispanic/Latina cohort. METHODS: Women aged 40-60 were surveyed in their preferred language (33% English, 67% Spanish) during screening mammography from 2016 to 2018. We used clinical BD classification from mammography records from 2013 (NYS DBN enactment) through enrollment (baseline) to create a 6-category variable capturing prior and new DBN receipt (sent only after clinically dense mammograms). We used this variable to compare the number of subsequent mammograms (0, 1, ≥ 2) from 10 to 30 months after baseline using ordinal logistic regression. RESULTS: In a sample of 728 women (78% foreign-born, 72% Hispanic, 46% high school education or less), first-time screeners and women who received DBN for the first time after prior non-dense mammograms had significantly fewer screening mammograms within 30 months of baseline (Odds Ratios range: 0.33 (95% Confidence Interval (CI) 0.12-0.85) to 0.38 (95% CI 0.17-0.82)) compared to women with prior mammography but no DBN. There were no differences in subsequent mammogram frequency between women with multiple DBN and those who never received DBN. Findings were consistent across age, language, health literacy, and education groups. CONCLUSION: Women receiving their first DBN after previous non-dense mammograms have lower mammography participation within 2.5 years. DBN has limited influence on screening participation of first-time screeners and those with persistent dense mammograms.

Catalytic specificity and crystal structure of cystathionine γ-lyase from Pseudomonas aeruginosa.

The escalating drug resistance among microorganisms underscores the urgent need for innovative therapeutic strategies and a comprehensive understanding of bacteria's defense mechanisms against oxidative stress and antibiotics. Among the recently discovered barriers, the endogenous production of hydrogen sulfide (H2S) via the reverse transsulfuration pathway, emerges as a noteworthy factor. In this study, we have explored the catalytic capabilities and crystal structure of cystathionine γ-lyase from Pseudomonas aeruginosa (PaCGL), a multidrug-opportunistic pathogen chiefly responsible for nosocomial infections. In addition to a canonical L-cystathionine hydrolysis, PaCGL efficiently catalyzes the production of H2S using L-cysteine and/or L-homocysteine as alternative substrates. Comparative analysis with the human enzyme and counterparts from other pathogens revealed distinct structural features within the primary enzyme cavities. Specifically, a distinctly folded entrance loop could potentially modulate the access of substrates and/or inhibitors to the catalytic site. Our findings offer significant insights into the structural evolution of CGL enzymes across different pathogens and provide novel opportunities for developing specific inhibitors targeting PaCGL.

Father's Absence in the Mongolian gerbil (Meriones unguiculatus) is associated with alterations in paternal behavior, T, cort, presence of ERα, and AR in mPOA/ BNST.

Testosterone (T), estrogen receptor alpha (ERα), and androgen receptor (AR) play a significant role in the regulation of paternal behavior. We determined the effects of deprivation of paternal care on alterations in paternal behavior, T concentrations in plasma, and the presence of ERα and AR in the medial preoptic area (mPOA), bed nucleus of the stria terminalis (BNST), medial amygdala (MeA), and olfactory bulb (OB), as well as the corticosterone (CORT) concentrations in plasma caused by deprivation of paternal care in the Mongolian gerbil (Meriones unguiculatus). Twenty pairs of gerbils were formed; the pups were deprived of paternal care (DPC) in 10 pairs. In another 10 pairs, the pups received paternal care (PC). Ten males raised in DPC condition and 10 males raised in PC conditions were mated with virgin females. When they became fathers, each DPC male and PC male was subjected to tests of paternal behavior on day three postpartum. Blood samples were obtained to quantify T and CORT concentrations, and the brains were removed for ERα and AR immunohistochemistry analyses. DPC males gave less care to their pups than PC males, and they had significantly lower T concentrations and levels of ERα and AR in the mPOA and BNST than PC males. DPC males also had higher CORT concentrations than PC males. These results suggest that in the Mongolian gerbil father's absence causes a decrease in paternal care in the offspring, which is associated with alterations in the neuroendocrine mechanisms that regulate it.

Training Promotoras to Implement a Mindfulness-based Healthy Lifestyle Program in Rural Communities.

Partnering with promotoras to implement a healthy lifestyle intervention has proven efficacious in reaching community members whom they serve. However, there are no clearly defined guidelines for implementing promotora training, especially when it involves developing mindfulness skills in promotoras unfamiliar with this concept. This is a report about the facilitators and barriers to training promotoras to implement a mindfulness-enhanced healthy eating and physical activity intervention, ADAPT+, using the Train-the-Trainer model. Following this model, we laid the foundations for sustained implementation of ADAPT+ even after the training process. Future studies may examine how these guidelines help map promotora training in other mindfulness-related interventions.

SUMOylation controls Hu antigen R posttranscriptional activity in liver cancer.

The posttranslational modification of proteins critically influences many biological processes and is a key mechanism that regulates the function of the RNA-binding protein Hu antigen R (HuR), a hub in liver cancer. Here, we show that HuR is SUMOylated in the tumor sections of patients with hepatocellular carcinoma in contrast to the surrounding tissue, as well as in human cell line and mouse models of the disease. SUMOylation of HuR promotes major cancer hallmarks, namely proliferation and invasion, whereas the absence of HuR SUMOylation results in a senescent phenotype with dysfunctional mitochondria and endoplasmic reticulum. Mechanistically, SUMOylation induces a structural rearrangement of the RNA recognition motifs that modulates HuR binding affinity to its target RNAs, further modifying the transcriptomic profile toward hepatic tumor progression. Overall, SUMOylation constitutes a mechanism of HuR regulation that could be potentially exploited as a therapeutic strategy for liver cancer.

Pintar y aprender a vivir sano / Painting and learning how to live healthy

El objetivo de este estudio surge de la necesidad en el centro de salud de mejorar el clima emocional de una sala de espera triste, apagada e inexpresiva y pasar a una estancia acogedora, amigable y educativa. Entendemos que la antesala de la consulta debe formar parte del cuidado global de la población infantil y la familia. Se buscaba mejorar el entorno físico del centro de salud en la zona de Pediatría. Al pintar las paredes del centro de salud tal vez no necesariamente se humanice el espacio, pero se hace más amable, intentando crear un sitio en el que el arte no solo aporte belleza, sino que sea una estrategia en educación de salud. Durante la espera no solo se dispondrá de un entorno atractivo y agradable, sino que además se fomentarán hábitos de vida saludables de forma creativa a través de dibujos que desarrollan historias con enseñanzas sobre la alimentación, la higiene, la amistad, etc. En las distintas fases del proyecto, se han implicado niños, profesores y el Ayuntamiento de Zaragoza, además de los profesionales sanitarios. Queremos reconocer de forma especial su contribución a la persona artífice del trabajo, Leticia García Longás. (AU)

The objective of this study arises in the health center from the need to improve the emotional environment, going from a sad, dull and inexpressive waiting room to a welcoming, friendly and educational one. We understand that the waiting room must be part of the global care of the children and their family. We looked for a physical improvement of the the pediatric area in the health center. Painting the walls of the health center may not humanize the space but it makes it friendlier, trying to create a place where art not only brings beauty but is also a health education strategy. During the wait, there won´t be only an attractive and pleasant environment, but also healthy lifestyle habits in a creative way through drawings that will develop stories with teachings about food, hygiene, friendship, etc. Children, teachers, the Zaragoza city council, health center professionals and especially the architect of the work, Leticia García Longás, have been involved in the different phases of the project.

Differences in Serum miRNA Profiles by Race, Ethnicity, and Socioeconomic Status: Implications for Developing an Equitable Ovarian Cancer Screening Test.

Serum miRNAs are promising biomarkers for several clinical conditions, including ovarian cancer. To inform equitable implementation of these tests, we investigated the effects of race, ethnicity, and socioeconomic status on serum miRNA profiles. Serum samples from a large institutional biobank were analyzed using a custom panel of 179 miRNA species highly expressed in human serum, measured using the Abcam Fireplex assay via flow cytometry. Data were log-transformed prior to analysis. Differences in miRNA by race and ethnicity were assessed using logistic regression. Pairwise t tests analyzed racial and ethnic differences among eight miRNAs previously associated with ovarian cancer risk. Pearson correlations determined the relationship between mean miRNA expression and the social deprivation index (SDI) for Massachusetts residents. Of 1,586 patients (76.9% white, non-Hispanic), compared with white, non-Hispanic patients, those from other racial and ethnic groups were younger (41.9 years ± 13.2 vs. 51.3 ± 15.1, P < 0.01) and had fewer comorbidities (3.5 comorbidities ± 2.7 vs. 4.6 ± 2.8, P < 0.01). On logistic regression, miRNAs predicted race and ethnicity at an AUC of 0.69 (95% confidence interval, 0.66-0.72), which remained consistent when stratified by most comorbidities. Among eight miRNAs previously associated with ovarian cancer risk, seven significantly varied by race and ethnicity (all P < 0.01). There were no significant differences in SDI for any of these eight miRNAs. miRNA expression is significantly influenced by race and ethnicity, which remained consistent after controlling for confounders. Understanding baseline differences in biomarker test characteristics prior to clinical implementation is essential to ensure instruments perform comparably across diverse populations. PREVENTION RELEVANCE: This study aimed to understand factors affecting miRNA expression, to ensure we create equitable screening tests for ovarian cancer that perform well in diverse populations. The goal is to ensure that we are detecting ovarian cancer cases earlier (secondary prevention) in women of all races, ethnic backgrounds, and socioeconomic means.

Impact of Flash Glucose Monitoring on the Fear of Hypoglycemia Phenomenon in Adults with Type 1 Diabetes.

Objective: To assess the clinical impact of flash glucose monitoring (FGM) systems on fear of hypoglycemia (FoH) and quality of life in adults with type 1 diabetes mellitus (T1DM). Methods: Prospective quasi-experimental study with a 12-month follow-up. People with T1DM (18-80 years old) and self-monitoring by blood capillary glycemia controls were included. The FH15 questionnaire, a survey validated in Spanish in a comparable study population, was used to diagnose FoH with a cutoff point of 28 points. Results: A total of 181 participants were included, with a FoH prevalence of 69% (n = 123). A mean reduction in FH15 score of -4 points (95% confidence interval [-5.5 to -3]; P < 0.001) was observed, along with an improvement in quality of life (EsDQOL-test (Diabetes Quality of Life, Spanish version), -7 points [-10; -4], P < 0.001) and satisfaction with treatment (Diabetes Treatment Satisfaction questionnaire, self-reported version [DTSQ-s] test, +4.5 points [4; 5.5], P < 0.001). At the end of the follow-up, 64.2% of the participants saw an improved FoH intensity, compared to 35.8% who scored the same or higher. This improvement in FoH status was associated with a higher time-in-range at the end of the follow-up (P = 0.003), as well as a lower time spent in hyperglycemia (P = 0.005). In addition, it was linked to participants with a high baseline FoH levels (P < 0.001) and those who were university degree holders (P = 0.07). Conclusions: FGM is associated with an overall reduction of FoH in adults with T1DM and with an increase in their quality of life. Nevertheless, a significant percentage of patients may experience an increase of this phenomenon leading to clinical repercussions and a profound impact on quality of life.

Blockchain based transparent and reliable framework for wheat crop supply chain.

The wheat crop that fulfills 35% of human food demand is facing several problems due to a lack of transparency, security, reliability, and traceability in the existing agriculture supply chain. Many systems have been developed for the agriculture supply chain to overcome such issues, however, monopolistic centralized control is the biggest hurdle to realizing the use of such systems. It has eventually gained consumers' trust in branded products and rejected other products due to the lack of traceable supply chain information. This study proposes a blockchain-based framework for supply chain traceability which provides trustable, transparent, secure, and reliable services for the wheat crop. A crypto token called wheat coin (WC) has been introduced to keep track of transactions among the stakeholders of the wheat supply chain. Moreover, an initial coin offering (ICO) of WC, crypto wallets, and an economic model are proposed. Furthermore, a smart contract-based transaction system has been devised for the transparency of wheat crop transactions and conversion of WC to fiat and vice versa. We have developed the interplanetary file system (IPFS) to improve data availability, security, and transparency which stores encrypted private data of farmers, businesses, and merchants. Lastly, the results of the experiments show that the proposed framework shows better performance as compared to previous crop supply chain solutions in terms of latency to add-blocks, per-minute transactions, average gas charge for the transaction, and transaction verification time. Performance analysis with Bitcoin and Ethereum shows the superior performance of the proposed system.

Shock score for prediction of clinical outcomes among stable patients with acute symptomatic pulmonary embolism.

BACKGROUND: The Composite Pulmonary Embolism Shock (CPES) score has been developed to identify normotensive patients with acute pulmonary embolism (PE) and a low cardiac index (referred to as normotensive shock). We aimed to externally assess the validity of this model for predicting a complicated course among hemodynamically stable patients with acute PE. METHODS: Using prospectively collected data from the PROgnosTic valuE of Computed Tomography scan (PROTECT) study, we calculated the CPES score for each patient and the proportion of patients with a score > 3. We calculated the test performance characteristics to predict a complicated course (i.e., death from any cause, hemodynamic collapse, or recurrent PE) and the discriminatory power using the area under the receiver operating characteristic curve. RESULTS: Sixty-three of the 848 (7.4 %) patients had a complicated course during the 30-day follow-up period. Of the 848 enrolled patients, the CPES score was positive (i.e., score > 3) in 78 (9.2 %). The specificity was 92.1 % (723/785), the positive predictive value was 20.5 % (16/78), and the positive likelihood ratio was 3.22 for a complicated course. The areas under the receiver operating characteristic curve for a complicated course were 0.71 (95 % confidence interval [CI], 0.65-0.78). With the higher score risk classification threshold (cutoff score > 4), the proportion of patients designated as positive was 2.1 %, and the specificity was 98.1 %. When echocardiographic right ventricle (RV) dysfunction was replaced by computed tomographic RV enlargement, the specificity was 85.4 %, the positive predictive value was 14.2 %, and the positive likelihood ratio was 2.06 for a complicated course. When analyses were restricted to the subgroup of patients with intermediate-risk PE, the specificity and the positive predictive value for a complicated course were identical to the overall cohort. CONCLUSIONS: The CPES score has acceptable C-statistic, excellent specificity, and low positive predictive value for identification of hemodynamic deterioration in normotensive patients with PE. CLINICALTRIALS: gov number: NCT02238639.

High-Sensitivity vs Conventional Troponin Cutoffs for Risk Stratification in Patients With Acute Pulmonary Embolism.

Importance: High-sensitivity troponin tests can detect even milder cardiac troponin elevations in plasma, beyond the threshold of conventional troponin tests. Whether detection of low-grade cardiac troponin elevation is associated with outcomes of patients with hemodynamically stable pulmonary embolism (PE) and helps with risk stratification is unknown. Objective: To determine the association between high-sensitivity cardiac troponin I (hs-cTnI) compared with conventional cardiac troponin I (cTnI) and PE risk designations according to the European Society of Cardiology (ESC) 2019 classification scheme and clinical outcomes in patients with hemodynamically stable PE. Design, Setting, and Participants: This is a post hoc analysis of data from the prospective Prognostic Value of Computed Tomography (PROTECT) multicenter cohort study enrolling patients from 12 hospital emergency departments in Spain. In this analysis, cTnI and hs-cTnI were compared with respect to ESC risk designation, and the association between troponin values and a complicated course after PE diagnosis was evaluated. Of 848 patients enrolled in PROTECT, 834 (98.3%) had hsTnI and cTnI values available and were included in the present analysis. Data were analyzed from May to December 2022. Exposures: Troponin blood testing with cTnI (threshold of >0.05 ng/mL) vs hs-cTnI (threshold of >0.029 ng/mL) assays at the time of PE diagnosis. Main Outcomes: Complicated course, defined as hemodynamic collapse, recurrent PE, or all-cause death, within 30 days after PE. Results: Of 834 patients (mean [SEM] age, 67.5 [0.6] years; 424 [50.8%] female), 139 (16.7%) had elevated cTnI and 264 (31.7%) elevated hs-TnI, respectively. During follow-up, 62 patients (7.4%; 95% CI, 5.7-9.4) had a complicated course. Analyzing troponin elevation as a binary variable, elevated cTnI (odds ratio [OR], 2.84; 95% CI, 1.62-4.98) but not hs-cTnI (OR, 1.12; 95% CI, 0.65-1.93) was associated with increased odds of a complicated course. Of 125 patients who had elevated hs-cTnI but normal cTnI, none (0; 95% CI, 0.0-2.9) developed a complicated course. Using the 2019 ESC risk stratification scheme, hs-TnI classified fewer patients as low risk compared with cTnI. Among 78 patients designated as ESC low risk when using cTnI but not with hsTnI, none (0; 95% CI, 0.0-4.6) had a complicated course. Conclusions and Relevance: In this study of patients with hemodynamically stable PE, hs-cTnI identified modest elevations in cardiac troponin levels. However, the results did not provide additive clinical value compared with cTnI. These findings suggest that use of hs-cTnI may result in overestimation of the risk in patients with stable PE.

Off-label Prescription in Paediatric Dermatology: A Retrospective Observational Study in a Tertiary Hospital.

Off-label prescription in paediatric patients is common, where some studies indicate that dermatological conditions are more prone to off-label treatment. This is the first study to analyse the prevalence of off-label prescription in paediatric dermatology consultation. This retrospective observational study was performed using the medical records of paediatric patients who were evaluated in a paediatric dermatological consultation in Pontevedra University Hospital, Pontevedra, Spain. Of the 468 patients reviewed, 186 prescriptions were issued and 51.10% were off-label prescription drugs. The dermatological conditions for which off-label prescription was most common were atopic dermatitis (29.0%), followed by warts (12.9%) and infantile haemangiomas (11.8%). With respect to drugs, topical tacrolimus (23.7%) was the most frequently prescribed off-label drug. The main reason for prescribing an off-label drug was for a disease not included on the label (62.4%), followed by issuing it at a lower age than authorized (55.9%). There was a significant association between a higher percentage of off-label prescription and younger age (p < 0.001), and the treatment of vitiligo, infantile haemangiomas and warts (p < 0.001). Likewise, the off-label prescription was significantly more common in the case of topical terbinafine, timolol, desloratadine and topical salicylic acid (p < 0.001). To conclude, off-label prescription is predominant in paediatric dermatology, as observed in 51.1% of our patients.

Ceft-to-Ceft Study: Real-Life Experience with Ceftaroline and Ceftobiprole in Treatment of the Principal Infectious Syndromes in a Spanish Multicenter Hospital Cohort.

BACKGROUND: To compare the real-life effectiveness and safety of ceftaroline fosamil (ceftaroline-F) and ceftobiprole medocaril (ceftobiprole-M) for infections in hospitalized patients. METHODS: This comparative, observational, retrospective, and multicenter Spanish study included patients receiving outpatient parenteral antimicrobial therapy (OPAT) and hospitalized patients treated for at least 48 h with ceftaroline-F or ceftobiprole-M between their first incorporation in the clinical protocol of each hospital and 31 July 2022. RESULTS: Ceftaroline-F was administered to 227 patients and ceftobiprole-M to 212. In comparison to the latter, ceftaroline-F-treated participants were younger (63.02 vs. 66.40 years, OR 1.1; 95%CI: 1.001-1.05) and had higher rates of septic shock (OR 0.27; 95%CI: 0.09-0.81) and higher frequencies of targeted (57.7 vs. 29.7%; OR: 0.35; 95%CI: 0.18-0.69) and combined (89.0 vs. 45.8%, OR: 0.13; 95%CI: 0.06-0.28) therapies that were second line or more (82.4% vs. 64.6%%; OR 0.35; 95%CI: 0.18-0.69), and higher rates of infections due to Gram-positive cocci (92.7 vs. 64.7%, p = 0.001), bacteremia (51.9 vs. 21.7%, p = 0.001), infective endocarditis (24.2 vs. 2.4%, p = 0.0001), and mechanical ventilation-associated pneumonia (8.8 vs. 2.4%, p = 0.0001). Ceftobiprole-M was more frequently administered against polymicrobial infections (38.1 vs. 14.0%, p = 0.001), those produced by Gram-negative bacilli (19.7 vs. 6.0%, p = 0.0001), nosocomial pneumonia (33 vs. 10.6%, p = 0.0001), and skin and soft-tissue infections (25.4 vs. 10.1%, p = 0.0001). Patients treated with ceftaroline-F had a longer hospital stay (36 (IQR: 19-60) vs. 19.50 (IQR: 12-30.75, p = 0.0001) days), with no difference in infection-related mortality at 14 (13.2 vs. 8.0%, p = 0.078) or 28 (4.8 vs. 3.3%, p = 0.415) days or in dropout rate for adverse effects (2.2 vs. 0.9%; p = 1). CONCLUSIONS: The fifth-generation cephalosporins, ceftaroline-F and ceftobiprole-M, are safe and effective in real life, with no difference between them in health outcomes.

Asymmetric post-translational modifications regulate the nuclear translocation of STAT3 homodimers in response to leukemia inhibitory factor.

STAT3 is a pleiotropic transcription factor overactivated in 70% of solid tumours. We have recently reported that inactivating mutations on residues susceptible to post-translational modifications (PTMs) in only one of the monomers (i.e. asymmetric) caused changes in the cellular distribution of STAT3 homodimers. Here, we used more controlled experimental conditions, i.e. without the interference of endogenous STAT3 (STAT3-/- HeLa cells) and in the presence of a defined cytokine stimulus (Leukemia Inhibitory Factor, LIF), to provide further evidence that asymmetric PTMs affect the nuclear translocation of STAT3 homodimers. Time-lapse microscopy for 20 min after LIF stimulation showed that S727 dephosphorylation (S727A) and K685 inactivation (K685R) slightly enhanced the nuclear translocation of STAT3 homodimers, while K49 inactivation (K49R) delayed STAT3 nuclear translocation. Our findings suggest that asymmetrically modified STAT3 homodimers could be a new level of STAT3 regulation and, therefore, a potential target for cancer therapy.
