Haemostatic gene variations in cervical cancer-associated venous thrombosis: considerations for clinical strategies.

Venous thromboembolism (VTE) is a life-threatening haemostatic disease frequently diagnosed among the cancer population. The Khorana Score is currently the primal risk assessment model to stratify oncological patients according to their susceptibility to VTE, however, it displays a limited performance. Meanwhile, intensive research on VTE pathophysiology in the general population has uncovered a range of single-nucleotide polymorphisms (SNPs) associated with the condition. Nonetheless, their predictive ability concerning cancer-associated thrombosis (CAT) is controversial. Cervical cancer (CC) patients undergoing chemoradiotherapy often experience VTE, which negatively affects their survival. Thus, aiming for an improvement in thromboprophylaxis, new thrombotic biomarkers, including SNPs, are currently under investigation. In this study, the predictive capability of haemostatic gene SNPs on CC-related VTE and their prognostic value regardless of VTE were explored. Six SNPs in haemostatic genes were evaluated. A total of 401 CC patients undergoing chemoradiotherapy were enrolled in a retrospective cohort study. The implications for the time to VTE occurrence and overall survival (OS) were assessed. CAT considerably impacted the CC patients' OS (log-rank test, P < 0.001). SERPINE1 rs2070682 (T > C) showed a significant association with the risk of CC-related VTE (CC/CT vs. TT, log-rank test, P = 0.002; C allele, Cox model, hazard ratio (HR) = 6.99 and P = 0.009), while F2 rs1799963 (G > A) demonstrated an important prognostic value regardless of VTE (AA/AG vs. GG, log-rank test, P = 0.020; A allele, Cox model, HR = 2.76 and P = 0.026). For the remaining SNPs, no significant associations were detected. The polymorphisms SERPINE1 rs2070682 and F2 rs1799963 could be valuable tools in clinical decision-making, aiding in thromboprophylaxis and CC management, respectively.

In vitro and in vivo evaluation of novel chromeno[2,3-d]pyrimidinones as therapeutic agents for triple negative breast cancer.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, and the limited therapeutic options show poor efficacy in patients, associated to severe side effects and development of resistance. Considering that chromene-based scaffolds proved to be attractive candidates for cancer therapy, herein we prepared new chromeno[2,3-d]pyrimidinone derivatives by a simple two step procedure, starting from the reaction of cyanoacetamide and a salicylaldehyde. A cell viability screening in several breast cancer cell lines allowed to identify two promising compounds with IC50 values in the low micromolar range for TNBC cells. These chromenes inhibited cell proliferation, induced cell cycle arrest and triggered cell death through apoptosis. In vivo studies revealed a safe profile in invertebrate and vertebrate animal models and confirmed their capacity to inhibit tumor growth in the CAM model, inducing significant tumor regression after 4 days of treatment. The two compounds identified in this study are promising drug candidates for TNBC treatment and valuable hits for future optimization, using the versatile synthetic platform that was developed.

Dense hydrated Mg-silicates in diamond: Implications for transport of H2O into the mantle.

Water in Earth's upper mantle is a minor and yet critically important component that dictates mantle properties such as strength and melting behavior. Minerals with stoichiometric water, such as those of the humite group, are important yet poorly characterized potential reservoirs for volatiles in the upper mantle. Here, we report observation of hydroxyl members of the humite group as inclusions in mantle-derived diamond. Hydroxylchondrodite and hydroxylclinohumite were found coexisting with olivine, magnesiochromite, Mg-bearing calcite, dolomite, quartz, mica, and a djerfisherite-group mineral in a diamond from Brazil. The olivine is highly forsteritic (Mg# 97), with non-mantle-like oxygen isotope composition (δ18O +6.2‰), and is associated with fluid inclusions and hydrous minerals-features that could be inherited from a serpentinite protolith. Our results constitute direct evidence for the presence of deserpentinized peridotitic protoliths in subcratonic mantle keels, placing important constraints on the stability of hydrous phases in the mantle and the origin of diamond-forming fluids.

10-year success story in CTEPH treatment: breaking the myth of rareness.

Unlike acute pulmonary embolism (PE), the resolution of thrombi is ineffective in chronic thromboembolic pulmonary hypertension (CTEPH), leading to reorganisation and fibrotic changes within the pulmonary arteries. The authors report the case of a man in his 60s with polycythemia vera, under warfarin, following an acute PE. He was admitted a year later with right heart failure and haemodynamic instability. Acute over chronic PE caused this severe presentation, confirmed by right heart catheterisation and pulmonary scintigraphy. The challenging diagnosis and management involved transfer to a centre specialised in pulmonary vascular disease. Normalisation of functional and haemodynamic parameters, sustained in 10-year follow-up, was achieved with anticoagulation and triple therapy with prostanoids as a bridge to pulmonary thromboendarterectomy. Targeted medical therapy, not standard at that time, was crucial to recovering conditions for transfer. An individualised approach, integrating multidisciplinary pulmonary hypertension expertise, provides the basis for the best care for CTEPH.

Gas-diffusion microextraction combined with HPLC-DAD for the comprehensive analysis of volatile carbonyl compounds in wood-based panels.

This work presents a novel application of gas-diffusion microextraction (GDME) combined with high-performance liquid chromatography with diode-array detection (HPLC-DAD) for the comprehensive analysis of volatile carbonyl compounds released from wood-based panels. GDME is a simple, fast, and environmentally friendly technique that allows the simultaneous extraction and derivatization of volatile carbonyls directly from solid samples. Commercial particleboards were analysed together with particleboard panels specifically produced using controlled conditions, materials, and reagents, to evaluate the differences in the emission profile of volatile carbonyl compounds. The effect of different production parameters, such as the type of wood particle, resin, and moisture content, on the emission profile of volatile carbonyls from particleboards was investigated using principal component analysis (PCA). The results showed that GDME-HPLC-DAD could successfully differentiate particleboards according to their emission of carbonyl compounds, such as formaldehyde, furfural, benzaldehyde, and other aliphatic carbonyls. Besides the differences on the emission of formaldehyde caused by the type of resin used, UF (urea-formaldehyde) and mUF (UF fortified with melamine), it was found that pine (Pinus pinaster Ait.) particleboards exhibit higher emissions of compounds such as acetaldehyde or hexanal when compared to the higher emissions of compounds such as furfural or benzaldehyde on the recycled particleboards.

Radiation Therapy Skin Marking with Lancets Versus Electric Marking Pen (COMFORTATTOO)-6 Months Results on Cosmesis, Fading, and Patients' Satisfaction From a Randomized, Double-Blind Trial.

Purpose: Most of radiation oncology centers rely on set-up skin markings for patient setup during treatment delivery. Permanent dark-ink tattooing is the most popular marking method. COMFORTATTOO is a unicentric, randomized trial testing 2 permanent methods: lancets against an electric marking pen (Comfort Marker 2.0, CM). One substudy was undertaken to test if using the CM translates into a cosmesis, fading, or satisfaction benefit compared with the lancets. Methods and Materials: Patients aged 18 years or older referred to our department to receive RT were recruited. They were randomly assigned, in a 1:1 ratio, to receive set-up markings using lancets or CM. This substudy aimed to recruit all the living participants included in the main study. The primary endpoints were tattoos cosmesis, tattoos fading, and patients' satisfaction 6 months after finishing the RT. Cosmetic and fading assessments were scored on a 5-point ascending scale and patients' satisfaction on a 10-point ascending scale. The trial is registered at ClinicalTrials.gov (number NCT05371795). Results: Between April and September 2022, 92 patients were enrolled (45 assigned to lancets and 47 to CM) and assessed for the outcomes. Patients receiving CM had significantly better cosmetic markings, with a median score of 4.4 (vs 3.7 for lancets, P<.001). On the fading assessment, the CM was associated with lower scores compared with the lancets (median score of 1.3 and 3.3, respectively; P<.001). No differences in patients' satisfaction were observed with either method (median score of 10 for both arms, P=.952). Conclusions: Our substudy results demonstrated that, 6 months after the end of RT, the CM produces better cosmetic markings with less fading compared with the lancets. These differences didn't translate into patients' satisfaction superiority toward any method.

Being a teacher in a time of pandemic.

This study was conducted in the context of the COVID-19 pandemic and, more specifically, within the research project 'Teaching and Learning in Times of COVID-19: Teachers' and Students' Perceptions in Cross-border Regions'. This study-conducted in Portugal-intended to diagnose the perceptions of basic education teachers and students regarding distance learning (D@L), considering a wide range of variables. This study was developed based on a multi-perspective approach, and data were collected via questionnaire surveys with open- and close-ended questions. In this study, we only intend to understand teachers' perceptions and, more specifically, issues pertaining to teaching professionalism. The results reflect teachers' perceptions of the transformations and challenges of D@L, the affirmation and recognition, and the ethical and deontological issues associated with the teaching profession following the educational changes imposed by the pandemic. More concretely, they suggest that D@L was accompanied by transformations or challenges that led to the reconfiguration of teaching and learning processes and contributed to the professional development of the study participants. However, the response trends differed because D@L has enabled the affirmation and social recognition of the teaching profession and raises ethical and deontological questions regarding the participants' professionalism.

Effect of overexpression of partial TDH1 and TDH2/3 gene sequences in a starter strain of industrial bioethanol fermentation on the Brettanomyces bruxellensis contaminant growth.

Selected Saccharomyces cerevisiae strains, such as the commercial Ethanol-Red (ER) strain, are used as starters in the bioethanol industry. Yet, bioethanol fermentations are prone to microbial contaminations, mainly by Brettanomyces bruxellensis and lactic acid bacteria. Chemicals, such as sulphuric acid and antibiotics, are commonly used to combat those contaminations, but they have negative environmental impacts. Recently, ER strain was found to secrete antimicrobial peptides (AMPs) active against B. bruxellensis. Therefore, the partial TDH1 and TDH2/3 genes sequences that codify those AMPs were inserted into the pSR41k plasmid and cloned in ER strains. The relative expression levels (plasmidic/genomic) of those sequences in the respective modified ER strains were quantified by real-time quantitative polimerase chain reaction (RT-qPCR), confirming their overexpression. The effect of the modified strains on B. bruxellensis (Bb) growth was then evaluated during synthetic must (SM) and carob syrup (CS) fermentations, co-inoculated with 105 cells ml-1 of ER and Bb in SM and with 106 of ER and 5 × 103 cells ml-1 of Bb in CS. Results showed that modified ER strains exerted a much higher inhibitory effect against B. bruxellensis (72-fold in SM and 10-fold in CS) than the non-modified ER strain. In those fermentations, 90-100 g l-1 of ethanol was produced in 3-6 days.

IROCA-TES: Improving Quality in Radiation Oncology through Clinical Audits - Training and Education for Standardization.

Background: Clinical audits are an important tool to objectively assess clinical protocols, procedures, and processes and to detect deviations from good clinical practice. The main aim of this project is to determine adherence to a core set of consensus- based quality indicators and then to compare the institutions in order to identify best practices. Materials and methods: We conduct a multicentre, international clinical audit of six comprehensive cancer centres in Poland, Spain, Italy, Portugal, France, and Romania as a part of the project, known as IROCATES (Improving Quality in Radiation Oncology through Clinical Audits - Training and Education for Standardization). Results: Radiotherapy practice varies from country to country, in part due to historical, economic, linguistic, and cultural differences. The institutions developed their own processes to suit their existing clinical practice. Conclusions: We believe that this study will contribute to establishing the value of routinely performing multi-institutional clinical audits and will lead to improvement of radiotherapy practice at the participating centres.

Transitioning intravenous epoprostenol to oral selexipag in idiopathic pulmonary arterial hypertension: a case report.

Intravenous (i.v.) prostacyclin is the cornerstone treatment in high-risk pulmonary arterial hypertension (PAH) patients. Selexipag is an orally available prostacyclin receptor agonist. Limited data are available regarding the feasibility of transitioning from i.v. epoprostenol to selexipag. A 50-year-old woman with idiopathic PAH was diagnosed in a World Health Organization (WHO) Functional Class (FC) IV. She improved with upfront triple combination therapy, including i.v. epoprostenol. Over 2 years of follow-up, the patient remained at low risk and expressed strong preference towards oral therapies. After careful risk-benefit clinical consideration, she was transitioned from i.v. epoprostenol to selexipag. Selexipag was started at dosage of 200 µg twice daily (b.i.d.) and titrated up to 1600 µg b.i.d. over 8 weeks (up-titration of 200 µg b.i.d. every week). Simultaneously, i.v. epoprostenol was down-titrated 3.0 ng/kg/min every week from a dosage of 27.5 ng/kg/min. The transition occurred under strict medical surveillance and was well tolerated. One year after discontinuation of epoprostenol, the patient remains in WHO FC I and has no signs of clinical deterioration. Although not generalizable to most PAH patients, this case highlights that a carefully planned transition from epoprostenol to selexipag is feasible in selected low-risk patients within a shared medical decision-making framework.

Thrombogenesis-associated genetic determinants as predictors of thromboembolism and prognosis in cervical cancer.

Venous thromboembolism (VTE) is a leading cause of death among cancer patients. Khorana score (KS) is the most studied tool to predict cancer-related VTE, however, it exerts poor sensitivity. Several single-nucleotide polymorphisms (SNPs) have been associated with VTE risk in the general population, but whether they are predictors of cancer-related VTE is a matter of discussion. Compared to other solid tumours, little is known about VTE in the setting of cervical cancer (CC) and whether thrombogenesis-related polymorphisms could be valuable biomarkers in patients with this neoplasia. This study aims to analyse the effect of VTE occurrence on the prognosis of CC patients, explore the predictive capability of KS and the impact of thrombogenesis-related polymorphisms on CC-related VTE incidence and patients' prognosis regardless of VTE. A profile of eight SNPs was evaluated. A retrospective hospital-based cohort study was conducted with 400 CC patients under chemoradiotherapy. SNP genotyping was carried on by using TaqMan® Allelic Discrimination methodology. Time to VTE occurrence and overall survival were the two measures of clinical outcome evaluated. The results indicated that VTE occurrence (8.5%) had a significant impact on the patient's survival (log-rank test, P < 0.001). KS showed poor performance (KS ≥ 3, χ2, P = 0.191). PROCR rs10747514 and RGS7 rs2502448 were significantly associated with the risk of CC-related VTE development (P = 0.021 and P = 0.006, respectively) and represented valuable prognostic biomarkers regardless of VTE (P = 0.004 and P = 0.010, respectively). Thus, thrombogenesis-related genetic polymorphisms may constitute valuable biomarkers among CC patients allowing a more personalized clinical intervention.

Modulation of the Berry Skin Transcriptome of cv. Tempranillo Induced by Water Stress Levels.

Climate change in the Mediterranean area is making summers warmer and dryer. Grapevine (Vitis vinifera L.) is mostly important for wine production in Mediterranean countries, and the variety Tempranillo is one of the most cultivated in Spain and Portugal. Drought decreases yield and quality and causes important economic losses. As full irrigation has negative effects on quality and water is scarce in this region, deficit irrigation is often applied. In this research, we studied the effects of two deficit irrigation treatments, Sustained Deficit Irrigation (SDI) and Regulated Deficit Irrigation (RDI), on the transcriptome of grape berries at full maturation, through RNAseq. The expression of differentially regulated genes (DEGs) was also monitored through RT-qPCR along berry development. Most transcripts were regulated by water stress, with a similar distribution of up- and down-regulated transcripts within functional categories (FC). Primary metabolism was the more severely affected FC under water stress, followed by signaling and transport. Almost all DEGs monitored were significantly up-regulated by severe water stress at veraison. The modulation of an auxin response repression factor, AUX22D, by water stress indicates a role of this gene in the response to drought. Further, the expression of WRKY40, a TF that regulates anthocyanin biosynthesis, may be responsible for changes in grape quality under severe water stress.

The governance of E-waste recycling networks: Insights from São Paulo City.

Electronic waste is an environmental problem because its production volume exceeds its recycling capacity. Academic and managerial production affirm two reasons: (a) dominant market logic and; (b) unresolved asymmetries among actors, causing conflicts to work together. Following the qualitative methodology, we investigate the e-waste situation in São Paulo City. The results allow us to propose that governance constructed by local actors could be a thoughtful way to promote e-waste recycling. Examples from around the world sustain this proposition. The theoretical principle is that the social process of constructing the mechanisms for collective action can solve challenges because the rules, roles, and actions are discussed and assumed by the actors working together. We present a matrix of indicators to be used in future studies in order to refine the proposition of constructed governance.

Cardanol-based adhesive with reduced formaldehyde emission to produce particleboards with waste from bean crops.

Free formaldehyde is a carcinogen whose emission reduction in particleboard has been studied recently to mitigate this environmental and human health problem. One alternative to reduce the emission of formaldehyde in particleboards is by using adhesives produced from natural sources. Cardanol-formaldehyde is an environmentally friendly adhesive made with cashew nut liquid, a byproduct from the cashew chain. This work aimed to produce particleboard using cardanol-formaldehyde in place of urea. In addition, different proportions of bean straw wastes were used to replace pine wood. The combination of eco-friendly adhesive and lignocellulosic waste particles could result in a product that meets market demands while being environmentally nonaggressive. Cardanol-formaldehyde promoted a higher modulus of elasticity (MOE) (1172 MPa) and modulus of rupture (MOR) (4.39 MPa) about panels glued with urea-formaldehyde, which presented a MOE of 764 MPa and MOR of 2.45 MPa. Furthermore, the cardanol-formaldehyde adhesive promoted a 93% reduction in formaldehyde emission, with a reduction from 16.76 to 1.09 mg/100 g oven-dry board for particleboards produced with cardanol-formaldehyde, indicating potential as an adhesive in the particleboard industry.

Development of an Innovative Lightweight Composite Material with Thermal Insulation Properties Based on Cardoon and Polyurethane.

The search for innovative and sustainable solutions to improve the energy efficiency of the construction industry has been a hot topic for researchers due to the tremendous impact of insulator materials in the thermal comfort of buildings. In the present work, an innovative lightweight composite material with thermal insulation properties was developed, for the first time, by using cardoon particles and polyurethane. The formulation of the composite material was optimized in terms of cardoon fraction and the polyol/isocyanate ratio, to achieve the best compromise between internal bond (IB) strength and thickness swelling (TS). The best performing composite was PU75-CP45, with 45 wt% of cardoon particles and 75% of isocyanate, achieving an IB of 0.41 MPa and a TS of 5.3%. Regarding insulation properties, the PU75-CP45 composite material exhibits a promising performance when compared to conventional construction industry materials by tuning its thickness. Additionally, the composite material presented very low emissions of volatile organic compounds and formaldehyde (bellow to legislation levels) and high resistance to biological degradation.

Physical activity and its clinical correlates in chronic thromboembolic pulmonary hypertension.

Limited data are available on physical activity (PhA) levels in chronic thromboembolic pulmonary hypertension (CTEPH) patients, as well as on the clinical utility of PhA measurements using questionnaires and accelerometers. We aimed to study PhA levels of CTEPH patients and their clinical correlates, and to compare PhA levels measured by the International Physical Activity Questionnaire (IPAQ) with measures from accelerometers. This is a cross-sectional study (n = 50). PhA levels were measured using accelerometers and questionnaires (IPAQ). Clinical parameters evaluated were walked distance on the 6-min-walking test (6MWT), pulmonary vascular resistance, N-terminal brain natriuretic peptide and quality of life (HRQoL) (Cambridge Pulmonary Hypertension Outcome Review questionnaire). Time spent in sedentary behavior was lower in self-reported measurement (279 ± 165 min/day) compared with accelerometry (446 ± 117 min/day, p < 0.000). Accelerometer-derived data showed that CTEPH patients spent 60% of the recorded time in sedentary behaviors and 2% in moderate-to-vigorous PhA (MVPA). Correlation analysis showed that MVPA was significantly correlated with 6MWT (p = 0.023) and symptom domain of HRQoL (p = 0.044). Self-reported MVPA was significantly higher than the one registered by the accelerometer (411 ± 569 vs. 131 ± 108 min/week, p = 0.027). Bland-Altman analysis indicated poor agreement between the two methods. Our results showed that CTEPH patients spend most of their days in sedentary behaviors and only a small amount of time in MVPA. Only MVPA was associated with HRQoL and CTEPH severity. In addition, we showed a poor agreement between self-reported and accelerometer-derived PhA in CTEPH patients, with the former overestimating the overall PhA.

Developmental Regulation of Transcription in Touriga Nacional Berries under Deficit Irrigation.

Grapevine (Vitis vinifera L.) is one of the most economically important crops worldwide, especially due to the economic relevance of wine production. Abiotic stress, such as drought, may contribute to low yield, shifts in quality, and important economic loss. The predicted climate change phenomena point to warmer and dryer Mediterranean environmental conditions; as such, it is paramount to study the effects of abiotic stress on grapevine performance. Deficit irrigation systems are applied to optimize water use efficiency without compromising berry quality. In this research, the effect of two deficit irrigation strategies, sustained deficit irrigation (SDI) and regulated deficit irrigation (RDI), in the grape berry were assessed. The effects of different levels of drought were monitored in Touriga Nacional at key stages of berry development (pea size, véraison, and full maturation) through RNA-Seq transcriptome analysis and by specific differentially expressed genes (DEGs) monitoring through RT-qPCR. Handy datasets were obtained by bioinformatics analysis of raw RNA-Seq results. The dominant proportion of transcripts was mostly regulated by development, with véraison showing more upregulated transcripts. Results showed that primary metabolism is the functional category more severely affected under water stress. Almost all DEGs selected for RT-qPCR were significantly upregulated in full maturation and showed the highest variability at véraison and the lowest gene expression values in the pea size stage.
