RESUMO
PURPOSE: Cancer imposes a substantial financial burden on patients because of the high out-of-pocket expenses and the significant hardships. Financial toxicity describes the impact of cancer care costs at the patient level. Although the financial impact of cancer has been recognized, understanding the extent and determinants of financial toxicity in specific contexts is crucial. This study investigated the level of financial toxicity and its associated factors among patients with cancer at an oncology hospital in central Vietnam. METHODS: This cross-sectional study included 334 patients with cancer. Direct interviews and medical record reviews were used for data collection. Financial toxicity was assessed using the 11-item Comprehensive Score for financial Toxicity (COST). A logistic regression model was used to determine factors associated with financial toxicity. RESULTS: A notable 87.7% of patients experienced financial toxicity due to cancer cost, with 37.7% experiencing mild financial toxicity and 49.7% suffering from moderate financial toxicity, 0.3% reporting severe financial toxicity. Individuals with low household income exhibited a higher proportion of financial toxicity compared to that of those with higher income (odds ratio (OR) = 5.78, 95% confidence interval (CI): 1.29-25.68). Compared with that of participants in the early stages, a higher burden was found in patients with advanced-stage cancer (OR = 3.88, 95% CI: 1.36-11.11). CONCLUSION: Our study indicates that patients with cancer in Vietnam facefinancial toxicity. It is thus necessary for interventions to mitigate the financial burden on patients with cancer, focusing on vulnerable individuals and patients in the advanced stages.

Adult stem cells play a crucial role in tissue homeostasis and repair through multiple mechanisms. In addition to being able to replace aged or damaged cells, stem cells provide signals that contribute to the maintenance and function of neighboring cells. In the lung, airway basal stem cells also produce cytokines and chemokines in response to inhaled irritants, allergens, and pathogens, which affect specific immune cell populations and shape the nature of the immune response. However, direct cell-to-cell signaling through contact between airway basal stem cells and immune cells has not been demonstrated. Recently, a unique population of intraepithelial airway macrophages (IAMs) has been identified in the murine trachea. Here, we demonstrate that IAMs require Notch signaling from airway basal stem cells for maintenance of their differentiated state and function. Furthermore, we demonstrate that Notch signaling between airway basal stem cells and IAMs is required for antigen-induced allergic inflammation only in the trachea where the basal stem cells are located whereas allergic responses in distal lung tissues are preserved consistent with a local circuit linking stem cells to proximate immune cells. Finally, we demonstrate that IAM-like cells are present in human conducting airways and that these cells display Notch activation, mirroring their murine counterparts. Since diverse lung stem cells have recently been identified and localized to specific anatomic niches along the proximodistal axis of the respiratory tree, we hypothesize that the direct functional coupling of local stem cell-mediated regeneration and immune responses permits a compartmentalized inflammatory response.
RESUMO
In an attempt to mitigate transfusion-related acute lung injury (TRALI), the Oslo Blood Center screened 1369 thrombapheresis donors for human leucocyte antigen (HLA)-specific antibodies. Anti-HLA antibodies were found in 200 donors who were deferred from donation of plasma-rich products. In a retrospective study, 2562 transfusions of thrombocytes (both apheresis and whole blood-derived) from 150 of these donors were subject to a thorough look back-investigation. Reports of 14 transfusion reactions were identified, none of which were classified as TRALI. Our study supports previous data indicating that the risk of TRALI is low. The value of screening for anti-HLA antibodies and subsequent deferral of donors with high levels of such antibodies remains questionable.

OBJECTIVES: This study was conducted to measure financial toxicity (FT) among patients with cancer in Vietnam using the COmprehensive Score for financial Toxicity (COST) and to describe the cost management strategies employed by these patients. METHODS: This comprehensive cross-sectional study enrolled 634 patients from 2 specialized oncology hospitals in Vietnam. Using COST cut-off scores, FT was classified as none/mild (≥26), moderate (14-25), or severe (≤13). Cost management strategies, or coping mechanisms, were classified into 4 groups: lifestyle changes, financial resource strategies, treatment modifications, and support seeking. RESULTS: The prevalence of FT was 91.8%, with 51.7% of participants demonstrating severe and 40.1% exhibiting moderate FT. Severe FT was significantly associated with female, low education level, unstable employment, low household economic status, and advanced cancer stage. The most common coping strategies were as follows: among lifestyle changes, reducing spending on basic items and leisure activities (78.7%) and cutting back on essential household expenses (66.4%); among financial resource strategies, borrowing money from relatives or friends (49.1%) and withdrawing funds from retirement or savings accounts (34.1%); within treatment modifications, switching treatment facilities or doctors due to cost concerns (9.3%); and within support seeking, obtaining help from welfare or community organizations (18.8%). All strategies were significantly more likely to be used by patients with severe FT. CONCLUSIONS: FT was highly prevalent among patients with cancer. Most patients relied on lifestyle adjustments and coping strategies, underscoring the need for improved financial support systems to alleviate the economic burden associated with cancer care.

Pinostrobin demonstrated anticancer properties, but its hydrophobic feature led to a reduction in bioavailability. The mitochondria-targeted approach successfully synthesized eight new alkyl triphenylphosphonium pinostrobin derivatives (1-8) with good yield in this study. Seven compounds (1-3, 5-8) showed greater cytotoxic potency against the human MCF-7 breast cancer cell line than pinostrobin. Molecular docking studies were performed with two important targets in hormone-dependent anticancer strategies, estrogen receptor α (ERα) ligand binding domains, 3ERT (antagonist recognition and antiproliferative function), and 1GWR (agonist recognition and pro-proliferative function). In addition, the MD simulation study of the two most potent compounds (2 and 3) complexed with both ERα forms suggested that compounds 2 and 3 could serve as favourable antagonists. Furthermore, the in silico ADMET prediction indicated that compounds 2 and 3 could be potential drug candidates.

Plants of the Zingiberaceae family, specifically those belonging to the Curcuma species, are commonly under consideration as potential therapeutic agents for the management of gastrointestinal diseases. In this study, we carried out a phytochemical study on Curcuma aromatica Salisb. (or so-called "Nghe trang" in Vietnamese) grown in Vietnam, which yields three newly discovered 3,5-diacetoxy diarylheptanoids (1-3) and six known 3,5-dihydroxyl diarylheptanoids (4-9). The bioactivity assessment shows that all isolated compounds, except compounds 3, 7, and 8, could inhibit urease. Compounds 4 and 9 significantly inhibit urease, with an IC50 value of 9.6 and 21.4 µM, respectively, more substantial than the positive control, hydroxyurea (IC50 = 77.4 µM). The structure-activity relationship (SAR) of linear diarylheptanoids was also established, suggesting that the hydroxyl groups at any position of skeleton diarylheptanoids are essential for exerting anti-urease action. Through a comparative analysis of the binding sites of hydroxyurea and diarylheptanoid compounds via our constructed in silico model, the mechanism of action of diarylheptanoid compounds is predicted to bind to the dynamic region close to the dinickel active center, resulting in a loss of catalytic activity. Such insights certainly help design and/or find diarylheptanoid-based compounds for treating gastric ulcers through inhibiting urease.
RESUMO
Tomato (Solanum lycopersicum L.) is one of the most important crops in the world for its fruit production. Advances in cutting-edge techniques have enabled the development of numerous critical traits related to the quality and quantity of tomatoes. Genetic engineering techniques, such as gene transformation and gene editing, have emerged as powerful tools for generating new plant varieties with superior traits. In this study, we induced parthenocarpic traits in a population of elite tomato (ET) lines. At first, the adaptability of ET lines to genetic transformation was evaluated to identify the best-performing lines by transforming the SlANT1 gene overexpression cassette and then later used to produce the SlIAA9 knockout lines using the CRISPR/Cas9 system. ET5 and ET8 emerged as excellent materials for these techniques and showed higher efficiency. Typical phenotypes of knockout sliaa9 were clearly visible in G0 and G1 plants, in which simple leaves and parthenocarpic fruits were observed. The high efficiency of the CRISPR/Cas9 system in developing new tomato varieties with desired traits in a short period was demonstrated by generating T-DNA-free homozygous sliaa9 knockout plants in the G1 generation. Additionally, a simple artificial fertilization method was successfully applied to recover seed production from parthenocarpic plants, securing the use of these varieties as breeding materials.

RESUMO
Myocardial infarction (MI) commonly known as "heart attack" results from the blockage of blood flow to the heart. Postmenopausal women face an elevated risk of MI due to declining estrogen levels, a hormone pivotal in maintaining cardiovascular health. It promotes vasodilation, reduce inflammation, and improves lipid profiles. While estrogen therapy shows promise in mitigating MI risk for postmenopausal woman, its efficacy in prevention and recovery remains a subject of debate. This review provides a critical assessment of existing evidence on estrogen therapy's cardioprotective effects for postmenopausal women. It delves into estrogen's role in vascular function enhancement, inflammation reduction, and lipid metabolism modulation. Additionally, it addresses the various forms of estrogen therapy, administration methods, dosage considerations, safety implications, and associated risks. The review highlights the existing controversies and knowledge gaps related to estrogen therapy for MI prevention. It underscores the urgency for in-depth research to decipher the nexus between estrogen therapy and MI risk, especially concerning primary prevention and specific postmenopausal subgroups. Future studies should investigate optimal formulations, doses, and administration routes of estrogen therapy as well as assess treatment timing and duration. Comparative studies and long-term follow-up are necessary to inform clinical decision-making and improve patient care. Addressing these research gaps will empower clinicians to make more judicious choices about estrogen therapy for MI prevention and recovery in postmenopausal women, aiming for enhanced patient outcomes.

OBJECTIVES: The objective of this study was to characterize mental health issues among Vietnamese healthcare workers (HCWs) and to identify related factors. METHODS: A cross-sectional study was conducted with 990 HCWs in 2021. Their mental health status was measured using the Depression, Anxiety, and Stress Scale. RESULTS: In total, 49.9%, 52.3%, and 29.8% of respondents were found to have depression, anxiety, and stress, respectively. The multivariable linear regression model revealed that factors associated with increased anxiety scores included depression scores (ß, 0.45; 95% confidence interval [CI], 0.39 to 0.51) and stress scores (ß, 0.46; 95% CI, 0.41 to 0.52). Factors associated with increased depression scores included being frontline HCWs (ß, 0.57; 95% CI, 0.10 to 1.10), stress scores (ß, 0.50; 95% CI, 0.45 to 0.56), and anxiety scores (ß, 0.41; 95% CI, 0.36 to 0.47), while working experience was associated with reduced depression scores (ß, -0.08; 95% CI, -0.16 to -0.01). Factors associated with increased stress scores included working experience (ß, 0.08; 95% CI, 0.00 to 0.16), personal protective equipment interference with daily activities (ß, 0.55; 95% CI, 0.07 to 1.00), depression scores (ß, 0.54; 95% CI, 0.48 to 0.59), and anxiety scores (ß, 0.45; 95% CI, 0.39 to 0.50), while age was associated with reduced stress scores (ß, -0.12; 95% CI, -0.20 to -0.05). CONCLUSIONS: Specific interventions are necessary to enhance and promote the mental health of HCWs so they can successfully cope with the circumstances of the pandemic.

This study presents a phytochemical analysis of the leaves of Paramignya trimera, revealing the isolation of a new apotirucallane-type protolimonoid, identified as 25-O-methyl-1,2-dihydroprotoxylocarpin D (1), along with two known compounds (2 and 3). The known compounds were identified as (20S,21R,23R)-21,23-epoxy-7α,24,25-trihydroxy-21-O-methyl-3-oxoapotirucalla-14-ene (2) and 7α,24,25-trihydroxy-3-oxoapotirucalla-14-en-21,23-olide (3). The three apotirucallane-type protolimonoids (1-3) did not exhibit cytotoxicity against MCF-7 cells at a concentration of 100 µM. Interestingly, when MCF-7 cells were treated with compound 1 at various concentrations, a notable stimulatory response was observed, leading to a significant increase in cell viability, up to 127%.

RESUMO
Replication of the RNA genome of influenza A virus occurs in the nucleus of infected cells. The influenza nucleoprotein (NP) associated with the viral RNA into ribonucleoprotein complexes (vRNPs) is involved in the nuclear import of the viral genome. NP has two nuclear localization sequences (NLSs), NLS1 and NLS2. Most studies have concentrated on the role of NP's NLSs using in vitro-assembled or purified vRNPs, which may differ from incoming vRNPs released in the cytoplasm during an infection. Here, we study the contribution of the NP's NLSs to the nuclear import of vRNPs in a cell culture model system for influenza infection: human lung carcinoma cells infected with viruses containing NP-carrying mutations in NLS1 or NLS2 (NLS2MT), generated by reverse genetics. We found that cells infected with these mutant viruses were defective in the nuclear import of incoming vRNPs and produced reduced amounts of newly synthesized NP, newly assembled vRNP, and progeny virus. In addition, NLS2MT-infected cells were also defective in the nucleolar accumulation of NP, confirming the nucleolar localization role of NLS2. Our findings indicate that both NLS1 and NLS2 have to be present for successful infection and demonstrate the crucial role of these two NLSs in the infection cycle of the influenza A virus.

Kinases have been the focus of drug discovery programs for three decades leading to over 70 therapeutic kinase inhibitors and biophysical affinity measurements for over 130,000 kinase-compound pairs. Nonetheless, the precise target spectrum for many kinases remains only partly understood. In this study, we describe a computational approach to unlocking qualitative and quantitative kinome-wide binding measurements for structure-based machine learning. Our study has three components: (i) a Kinase Inhibitor Complex (KinCo) data set comprising in silico predicted kinase structures paired with experimental binding constants, (ii) a machine learning loss function that integrates qualitative and quantitative data for model training, and (iii) a structure-based machine learning model trained on KinCo. We show that our approach outperforms methods trained on crystal structures alone in predicting binary and quantitative kinase-compound interaction affinities; relative to structure-free methods, our approach also captures known kinase biochemistry and more successfully generalizes to distant kinase sequences and compound scaffolds.

RESUMO
OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. METHODS: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. RESULTS: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). CONCLUSIONS: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

RESUMO
Primary cardiac angiosarcoma is a rare and aggressive malignancy originating from the endothelial lining of cardiac blood vessels. This review covers various aspects of the disease, including its pathogenesis, clinical presentation, diagnosis, treatment, and prognosis. The primary characteristic of cardiac angiosarcoma is the rapid growth of abnormal blood vessels that invade the heart muscle, leading to the destruction of healthy tissue. Due to its infiltrative nature and early spread, diagnosing and treating cardiac angiosarcoma present significant challenges. Transesophageal echocardiography (TEE) plays a crucial role in diagnosing cardiac tumors such as angiosarcoma due to its high sensitivity. Additional imaging techniques such as computed tomography (CT) and cardiac magnetic resonance imaging (MRI) help assess tumor anatomy and identify metastases. Histopathological examination and immunohistochemistry are essential for confirming the diagnosis, as they reveal distinct histological features and specific endothelial markers associated with primary cardiac angiosarcoma. Targeted therapies directed at the angiogenic mechanisms and molecular abnormalities hold promise for improving treatment outcomes. Early detection of primary cardiac angiosarcoma remains challenging due to its rarity, and the prognosis is generally poor due to advanced disease at the time of diagnosis. The review emphasizes the importance of a multidisciplinary approach and collaboration among different specialties to optimize the diagnosis, treatment, and follow-up care of patients with primary cardiac angiosarcoma. The ultimate goal is to enhance diagnostic methods and therapeutic approaches by advancing knowledge and promoting further research into this aggressive malignancy.
RESUMO
Fibrodysplasia ossificans progressiva (FOP), also known as Stoneman syndrome, is a rare genetic disorder characterized by abnormal bone development caused by activating mutations of the ACVR1 gene. FOP affects both the developmental and postnatal stages, resulting in musculoskeletal abnormalities and heterotopic ossification. Current treatment options for FOP are limited, emphasizing the need for innovative therapeutic approaches. Challenges in the development of management criteria for FOP include difficulties in recruitment due to the rarity of FOP, disease variability, the absence of reliable biomarkers, and ethical considerations regarding placebo-controlled trials. This narrative review provides an overview of the disease and explores emerging strategies for FOP treatment. Gene therapy, particularly the CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats-associated protein 9) system, holds promise in treating FOP by specifically targeting the ACVR1 gene mutation. Another gene therapy approach being investigated is RNA interference, which aims to silence the mutant ACVR1 gene. Small molecule inhibitors targeting glycogen synthase kinase-3ß and modulation of the bone morphogenetic protein signaling pathway are also being explored as potential therapies for FOP. Stem cell-based approaches, such as mesenchymal stem cells and induced pluripotent stem cells, show potential in tissue regeneration and inhibiting abnormal bone formation in FOP. Immunotherapy and nanoparticle delivery systems provide alternative avenues for FOP treatment.
RESUMO
From the EtOAc-soluble extract of the rhizomes of Zingiber montanum (J.Koenig) Link ex A.Dietr., a novel diphenylbutenoid, montadinin A (1) and a previously unreported phenylbutenoid compound, 1-(3,4-dimethoxyphenyl)but-3-en-2-ol (7), in natural source were isolated. Additionally, seven known phenylbutenoids were also identified. The structures of all compounds were elucidated through NMR spectroscopic interpretation. Compounds cis-3-(3,4-dimethoxyphenyl)-4-[(E)-3,4-dimethoxystyryl]cyclohex-1-ene (2), cis-4-[(E)-3,4-dimethoxystyryl]-3-(2,4,5-trimethoxyphenyl)cyclohex-1-ene (3), trans-3-(3,4,-dimethoxyphenyl)-4-[(E)-2,4,5-trimethoxystyryl]cyclohex-1-ene (5), and cis-3-(3,4-dimethoxyphenyl)-4-[(Z)-2,4,5-trimethoxylstyryl]cyclohex-1-ene (6) showed weak cytotoxicity against HepG2 cells with IC50 values of 122.9, 127.3, 257.5, and 168.5 µM, respectively.
