Spirituality is a crucial yet complex element of holistic nursing care, particularly when providing care for older adults with depression. In Thailand, depression poses a significant mental health challenge. Thai cultural values are deeply interwoven with individuals' beliefs, making spirituality a critical factor in addressing the care of older adults with depression. This study aimed to explore how older adults with depression experience spirituality and construct meaning from it in their daily lives.
An interpretative phenomenological study.
In-depth interviews of 30 older Thai adults living with depression (aged 60–85 years) from an outpatient psychiatric clinic in southern Thailand were conducted using semi-structured interview questionnaires. Interpretive phenomenological analysis was employed. Data were collected from June to August 2024.
Five themes emerged from the phenomenological data analysis: (1) elusiveness of spiritual meaning, (2) holding oneself together through inner power, (3) finding acceptance through faith in a higher power, (4) family ties shaping peace and despair, and (5) being guided and cared for.
This study highlights that older adults with depression perceive spirituality as essential for their well-being. Personal practices, such as meditation and chanting, played a key role in strengthening spirituality and reducing the risk of relapse in depressive symptoms, which are distinct for each older adult. Understanding spirituality's role in mental health guides nurses to develop strategies for providing more empathetic spiritual care.
Nurses must address depression in older adults through individualized practices to effectively empower their inner strength and coping mechanisms. Understanding each individual's spiritual practices is essential to help them harness their inner strength when coping with depression.
Sub-Saharan Africa (SSA) continues to be the hub of the global HIV/AIDS pandemic, globally. Despite several attempts to meet their HIV prevention needs, men continue to have high rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an effective treatment that, when taken as prescribed, can be very efficient in preventing and reducing the risk of HIV acquisition. HIV self-testing (HIVST) has been demonstrated to be acceptable among men in SSA. As such, this review aims to explore the existing literature on the integration of PrEP dispensing with HIVST among men in SSA.
We will systematically search bibliometric databases, including PubMed/MEDLINE, Embase, Scopus, the Cumulative Index to Nursing and Allied Health Literature Plus, Sociological Abstracts, ProQuest Dissertations and Theses global. Our review will be guided by the Arskey and O’Malley framework and Levac et al. The review results will be reported using the preferred reporting items for systematic reviews and meta-analysis: extension for scoping reviews guidelines. To assess the methodological quality of the included articles, the mixed methods appraisal tool version 2018 will be used. We will use NVivo software (V.11) to synthesise data from the included studies using a thematic approach.
Ethical approval is not required, as this review uses publicly available data. Findings will be disseminated through peer-reviewed publication, conference presentations and engagement with key stakeholders in HIV prevention and treatment across SSA.

Hypertension is one of the main causes of cardiovascular diseases worldwide, affecting over one billion people. Although aliskiren offers a valuable option for inhibiting the renin-angiotensin system, its safety profile in the real world remains insufficiently explored, especially for rare or under-recognized adverse events (AEs), which have not been fully clarified. Therefore, leveraging large-scale post-marketing surveillance data is crucial for identifying rare AEs and guiding safer clinical practice. This study aims to elucidate pharmacovigilance signals associated with aliskiren (an antihypertensive drug) by systematically analyzing the characteristics of adverse events (AEs) from the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database and WHO-VigiAccess database, which provides a reliable scientific basis for clinical practice and regulatory decision-making. We conducted a retrospective quantitative analysis of aliskiren-related AE reports from the aforementioned two databases, employing the Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-item Gamma Poisson Shrinker (MGPS) algorithms for signal detection. The results indicate that there were 5,596 and 5,549 aliskiren-related reports in the FAERS and WHO-VigiAccess databases, respectively. The median duration of these AEs during the observation period was 62 days, with an interquartile range (IQR) of 7–282 days. In both databases, signals for aliskiren were distributed across 28 System Organ Classes (SOCs), among which investigations, cardiac disorders, renal and urinary disorders, vascular disorders, and metabolism and nutrition disorders exhibited significant signals based on specific criteria applied across the four algorithms. A total of 607 preferred terms (PTs) with significant disproportionality signals were detected using the four algorithms, including potential AEs not previously well-documented, such as palpitations, myalgia, proteinuria, muscular weakness, pulmonary edema, and pollakiuria. This study not only confirms the known adverse reactions of aliskiren but also uncovers new potential risks, highlighting the importance of strengthening drug safety monitoring to enhance therapeutic efficacy and reduce the risk of adverse reactions. It provides valuable safety insights for physicians considering the use of aliskiren in the management of primary hypertension.by Mingming Pan, Yanhua Shen, Jiayu Wu, Chaonan Liu, Meihong Zhu, Zhengyu Zhou
This study aimed to investigate the therapeutic effects of ELASEM®Flex and ELASEM®ProFlex, two eggshell membrane (EM) products, on sodium iodoacetate (MIA)-induced osteoarthritis (OA) in rats. An OA model was established by a single intra-articular injection of MIA into the knee joint. After modeling, rats were administered diclofenac sodium, ELASEM®Flex, and ELASEM®ProFlex by gavage daily for 4 consecutive weeks. During the experiment, food intake, water intake, body weight, and plantar mechanical pain threshold (MPT) of rats were measured weekly. Serum levels of TNF-α, COX-2, IL-1β, and CTX-II were assessed at weeks 2 and 4. After 4 weeks, knee joints were harvested for histopathological examination (HE staining and Safranin-O fast green staining). Results indicated that knee joints of OA rats showed significant swelling, which was alleviated to varying degrees in all treatment groups. Both ELASEM®Flex and ELASEM®ProFlex significantly increased the MPT (P ®Flex and ELASEM®ProFlex can exert preventive and reparative effects on knee OA in rats by alleviating arthritis pain, inhibiting inflammatory factor expression, reducing type II collagen degradation, and promoting chondrocyte proliferation.To compare the effectiveness of multifactorial and exercise programs in preventing falls among older adults, with a specific focus on evaluating the individual and combined contributions of their key intervention components.
This study was a systematic review and component network meta-analysis. PubMed, Embase, and Web of Science were searched from inception to February 2025 for randomized controlled trials, focusing on four primary outcomes: fallers, recurrent fallers, injurious fallers, and fractured fallers. Risk of bias was evaluated using the Cochrane tool, and additive component network meta-analysis compared intervention group and component efficacy.
69 randomized controlled studies were included. In multifactorial interventions, traditional health education could increase fall risk (iRR: 1.10, 95% CI [1.03; 1.67]) and recurrent fall risk (iRR: 1.25, 95% CI [1.06; 1.48]). Medication management can increase recurrent fall risk (iRR: 1.35, 95% CI [1.09; 1.67]) and fracture risk (iRR: 2.11, 95% CI [1.48; 3.00]). Exercise (iRR: 1.24, 95% CI [1.01; 1.53]) increased fracture risk, and environment modification (iRR: 0.56, 95% CI [0.61; 0.79]) reduced it. The additive effect of risk assessment and advice, exercise, and environment modification reduced fall risk. In exercise programs, gait and balance (iRR: 0.58, 95% CI [0.36; 0.93]) can reduce recurrent fall risk. An intervention containing two components (gait and balance + strength and resistance) reduced the risk of falls and fall-related injuries.
Environment modification reduced fracture risk, emphasizing the value of creating safe living spaces. The combination of risk assessment, advice, exercise, and environment modification reduced fall risk, suggesting a holistic approach may be effective in preventing falls. Traditional methods of health education and medication management are in urgent need of updating to synergize with other exercise components and enhance the effectiveness of fall prevention. Prospective clinical trials are needed to optimize combinations of exercise components, particularly integrating gait and balance training with strength and resistance exercises.
The review was registered online in the International Prospective Register of Systematic Reviews (PROSPERO) under registration number (CRD42025643530)
To evaluate the impact of a 5-min delay in needle removal after haemodialysis on complications and patient satisfaction in newly created arteriovenous fistulas.
Retrospective cohort study.
This study analysed 109 patients with new arteriovenous fistulas undergoing initial cannulation 8–12 weeks post-surgery. Participants were divided into two cohorts: a conventional group (n = 42) receiving immediate needle removal after pump cessation, and a delayed group (n = 67) retaining needles for 5 min post-pump cessation before removal. Outcomes included haemostasis time, hematoma incidence, 3-month reintervention rates, and patient satisfaction measured by a 5-point scale.
Delaying needle removal by 5 min reduced mean haemostasis time by 32% compared to immediate removal (16.4 min vs. 24.1 min). Hematoma incidence decreased substantially by 76% in the delayed group (3.3% vs. 13.1%). At 3-month follow-up, reintervention rates were 66% lower with delayed removal (9.0% vs. 26.2%). Patients also reported 50% less procedure-related pain and significantly higher satisfaction scores (median 4.5 vs. 2).
A brief 5-min delay in needle removal significantly reduces complications and enhances patient-centered outcomes during early arteriovenous fistula use.
This protocol establishes an evidence-based standard for post-dialysis needle management, directly reducing compression-induced pain and reintervention needs while requiring no additional nursing resources. Implementation can immediately improve vascular access safety in haemodialysis units.
The study addresses high complication rates (26.2%) from immediate needle removal in immature fistulas. Key findings demonstrate 76% fewer hematomas and 66% lower reinterventions with 5-min delayed removal. This evidence may transform global haemodialysis nursing protocols, benefiting a substantial population of patients receiving new fistulas annually.
This study follows the STROBE checklist.

This study aims to explore the history of prior abortions and the factors influencing them among young women seeking abortion services in Foshan, Guangdong, China.
This is a retrospective, cross-sectional study of young women seeking abortion care.
Gynaecological outpatient clinics at the Department of Gynaecology, Foshan Women and Children Hospital Affiliated to Guangdong Medical University, Foshan, Guangdong, China, between 2013 and 2023.
A total of 7361 young women aged 12–25 years seeking abortion services.
Data on abortion history, sociodemographic factors, contraceptive use and postabortion contraceptive choices were collected and analysed, with special emphasis on the incidence of repeat abortions and the factors associated with them.
Of the 7361 participants, 34.2% reported at least one previous abortion, underscoring a notable public health concern. The mean age of the participants was 22.30 years (SD=2.13). Women with a history of abortion were significantly older than those without (22.57 vs 22.08 years, p
This study underscores the need for targeted interventions to address the multifaceted factors leading to repeat abortions among young women in China. The results offer valuable insights for improving reproductive health outcomes in this vulnerable population and highlight the importance of expanding access to contraceptive education and services in China.

Multimorbidity, the presence of multiple chronic health conditions, is a leading cause of death globally. In Malawi, chronic noncommunicable and communicable diseases such as HIV frequently co-exist, putting pressure on an under-resourced system. However, the health system is primarily structured around disease-specific [vertical] programs, which hinders person-centred care approaches to multimorbidity. Our study focuses on multimorbidity care and explores the perceptions of healthcare workers on the patient pathways and service organisation throughout the patient’s interaction with the health facilities. This cross-sectional qualitative study took an interpretivist approach. We conducted 13 days of clinical observations at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. We also conducted 13 days of clinical observations and semi-structured in-depth interviews with different cadres of purposively sampled healthcare workers (n = 22) at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. Through thematic analysis, we identified an understanding of the organisation of care and healthcare workers’ perspectives on the delivery of services. Findings showed both hospitals provided services for inpatients and outpatients with multimorbidity, including screening, management, prevention of secondary conditions and rehabilitation. Patient diagnosis and management for multimorbidity were often delayed due to frequent stockouts of medication and consumables necessary for diagnostic testing for NCDs at the hospital level. Some healthcare workers were not equipped with the knowledge, skills, or guidelines to manage multimorbidity. As HIV care is currently better resourced than other chronic conditions, healthcare facilities may strengthen the supply chain, healthcare workers’ training sessions and monitoring and evaluation tools to ensure NCDs are well managed, learning from HIV programmes.by Cecilia Aguilar-Vega, Jaime Bosch, Satoshi Ito, Benjamin Ivorra, Hyunkyu Jeong, José Manuel Sánchez-Vizcaíno
African swine fever (ASF) is a lethal disease of swine that has spread across Asia since its introduction in 2018. South Korea first reported the disease in September 2019 in domestic pigs, and since then, more than 4,000 cases have been reported in wild boars during its expansion up to August 2024. Due to the high number of ASF notifications in wild boars in South Korea, contrasted with their scarcity in most Asian countries, analyzing the spatiotemporal spread of the disease in a setting with active surveillance provides valuable insights. In this study, we performed a trend-surface analysis on temporally gridded case data to characterize the overall geographic spread and direction of ASF in wild boars across South Korea, from its emergence to August 2022. Additionally, we propose a novel approach distinct from previous studies, to estimate spread velocity by incorporating an upper threshold to avoid unrealistic values. The model described the spread of ASF in the study area. The disease showed greater expansion in the east of the country. Initially, a south and eastward direction was estimated. The estimated median velocity was 19.53 km/month, with cell-level velocities ranging from 2.45 to 69.99 km/month. Velocity increased notably from autumn 2021 onward and varied substantially across years. Our results show the dynamics of ASF in wild boars of South Korea, providing new evidence of their role in the epidemiology of the disease.by Hongjun Park, Beechui Koo, Jungwook Shin, Byoung Hyuck Kim, James J.

Approximately one-third of US adults have tattoos, yet the dosimetric impact of intradermal tattoo pigments during radiation therapy remains uncharacterized. Commercial tattoo inks contain unregulated metallic impurities including chromium, lead, and nickel, raising concerns about dose perturbations in tattooed skin. This work quantifies radiation dose perturbations induced by high-atomic-number (Z) tattoo pigments under clinically relevant radiotherapy conditions. Monte Carlo simulations (TOPAS) modeled layered skin phantoms with a 0.3-mm intradermal tattoo layer embedded at 1.25–1.55 mm depth. Three commercial inks were evaluated: carbon-based (black) and metal-containing (Fe-rich brown, Al-containing orange) at pigment loadings of 5–100 vol% within the tattoo layer, to establish upper-bound effects. Electron (6, 18 MeV) and photon (6, 18 MV) beams were simulated with standard clinical geometry (1 × 1 cm² field, SSD = 100 cm). Photon irradiation produced pronounced, depth-localized dose enhancement, with peak dose enhancement factor (DEF) reaching 2.5 for brown ink at 18 MV, a 62% mean increase relative to non-tattooed skin driven by high-Z–mediated secondary electron production. Electron beams exhibited energy-dependent behavior: 6 MeV produced modest enhancement (peak DEF ~ 1.07), while 18 MeV unexpectedly generated dose deficits (DEFby Metha Yaikwawong, Khanittha Kamdee, Kasarnchon Mek-yong, Somlak Chuengsamarn
This work aimed to clarify how polymorphisms in the TNF gene relate to metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), and a broad spectrum of cardiometabolic characteristics, while also determining their impact on circulating TNF‑α concentrations. A total of 765 participants were genotyped for rs1800629 and rs361525, and serum TNF-α was also measured. To assess these relationships, multivariable logistic regression models—incorporating age, sex, and body mass index (BMI)—were applied to estimate adjusted odds ratios (aORs) and their corresponding 95% confidence intervals (CIs). Both variants were significantly associated with MetS: rs1800629 (crude OR = 2.22, 95% CI: 1.45–3.44, P P P = 0.035; adjusted OR = 2.84, 95% CI: 1.17–7.31, P = 0.025). The rs1800629 variant was also linked to T2DM risk (adjusted OR = 2.61, 95% CI: 1.35–5.24, P = 0.006), whereas rs361525 showed no such association. Carriers of rs1800629 had higher mean TNF-α levels (PWell-being of healthcare professionals (HCPs) is vital for care quality, staff retention and overall healthcare system effectiveness. This study aims to identify the organisational and workplace variables associated with sick leave and measures of engagement of HCPs on department level within a single Dutch academic hospital.
Cross-sectional study using routinely collected organisational data.
A tertiary-care academic hospital in the Netherlands.
25 clinical departments were included. Department level variables were derived from routinely collected hospital databases. Availability of data varied across variables. Analysis included information on patient population, human resources, care processes, quality of care and employee and patient experiences to assess differences, correlations and predictors for sick leave and engagement.
Primary outcome measures were (1) sick leave (%) and (2) engagement, assessed through two staff-survey items (vitality and connectedness; 0–10 Numeric Rating Scale). Both outcomes were analysed at department level.
Employee population data showed the most consistent patterns across analyses. Departments with higher staffing capacity had higher sick leave and lower engagement in group comparisons (p=0.009, p=0.030, respectively). In multivariable models, higher staffing capacity remained associated with increased sick leave (B=1.38, 95% CI 0.53 to 2.23, p=0.003). Engagement was positively associated with higher inflow (B=0.92, 95% CI 0.06 to 1.77, p=0.037) and negatively associated with outflow (B = –1.36, 95% CI –2.08 to –0.63, p=0.001). No consistent associations were found with patient population and patient experience measures.
Workforce-related factors, particularly staffing capacity and inflow and outflow, are strongly linked to sick leave and engagement. Routinely collected hospital data can be used to identify at-risk departments and inform targeted strategies for improving workforce sustainability. Future studies should explore more granular, team-level data to better support staff well-being and care quality.
Colchicine has been shown to reduce cardiovascular events and may improve outcomes in arteriovenous fistulas used for haemodialysis due to antiproliferative effects. However, it is often avoided in patients receiving dialysis. Therefore, a large trial assessing the potential benefits of colchicine in dialysis patients cannot begin without further data on feasibility. The primary objective of this study is to assess the feasibility of carrying out future trials of colchicine in dialysis patients.
This is an open-label, single centre, single arm study with 100 participants. The primary outcome is feasibility and the decision to progress to a full-scale trial. This will be based on the consent rate and the colchicine discontinuation rate. Secondary objectives are testing the feasibility of data collection procedures relating to quality-of-life measures, vascular access interventions and safety. Other secondary objectives are to assess the utility of the electronic health record for collecting trial data and to explore patients’ and healthcare providers’ experiences and attitudes towards colchicine and a feasibility study.
The study has Research Ethics Committee approval (Wales REC 6; 24/WA/0277). It is intended that the results of the study will be reported in peer-reviewed scientific journals.
To explore the views of healthcare practitioners in Britain regarding the role of midwives and nurses in the delivery of medical and surgical abortion.
An observational study of the Shaping Abortion for Change study healthcare practitioner survey (2021–2022).
Relationships between healthcare practitioner type, participant characteristics, knowledge of and attitudes towards abortion, and views about nurses' and midwives' role in abortion care were examined using Pearson's Chi-squared tests of association and multivariable logistic regression.
Amongst 763 participants including doctors, nurses, midwives and pharmacists, 71.6% supported specialist nurses in sexual and reproductive health and abortion clinics and hospitals, expanding their roles to include prescribing abortion medications and surgical abortion methods. Support was lower for midwives (35.8%) and primary care nurses (32.5%). There was considerable support for all nursing and midwifery groups to be involved in adjacent tasks of abortion care. Differences in support by healthcare practitioner type persisted after adjustment for exposure variables.
There is strong support for specialist nurses to expand their role in abortion care. This change could be implemented following clarification of the legal position. Some healthcare practitioner groups are more reluctant to support broader involvement of nurses and midwives in abortion provision.
Expanding specialist nurses' role in abortion care could increase service capacity and improve patient access and experience. Understanding and addressing the concerns of healthcare practitioners opposing this change is critical for successful implementation and patient safety.
This study addresses the potential for nurse and midwife role expansion in abortion care. The findings highlight broad support for specialist nurses whilst identifying barriers to wider role expansion. The research informs policy discussions on workforce optimisation and access to abortion services across Britain.
This study adheres to the STROBE guidelines for reporting observational studies.
In the SACHA study, patient and public involvement was included at all stages to inform study design, recruitment, data collection and analysis.
Pressure injury (PI) is common in the ICU and not well captured by single-risk tools such as the Braden scale. We aimed to develop and internally validate a machine-learning model to predict new-onset PI using routinely collected ICU data. This retrospective single-centre cohort included adult ICU patients with length of stay ≥ 48 h (2018–2023). The primary outcome was new-onset PI during ICU stay. Candidate predictors were pre-specified: minimum albumin, maximum lactate, SOFA, APACHE II, first recorded Braden score, age, BMI, a nutrition score and treatment indicators. Missing values were imputed (median/mode). A gradient boosting model (GBM) was evaluated with stratified 3-fold cross-validation; a random forest (RF) served as a benchmark (stratified 70/30 train–test split). Discrimination (AUC) was primary; calibration, Brier score, decision-curve analysis (DCA) and feature importance were secondary. Logistic regression quantified independent associations. Among included ICU stays, 14.6% developed PI. On multivariable analysis, higher lactate, lower albumin, lower Braden scores, older age, CRRT, prone positioning, enteral nutrition and analgesic exposure were associated with increased PI risk, whereas sedatives showed an inverse association. The GBM achieved AUC≈0.69 with acceptable calibration and net clinical benefit across thresholds commonly used in preventive workflows (≈0.10–0.50). Single markers or simple combinations displayed only modest discrimination. A GBM built from routine ICU data provided moderate, well-calibrated discrimination for predicting new-onset PI and demonstrated decision-relevant net benefit. The model can complement Braden-based screening by refining risk stratification and prioritising intensified prevention for patients most likely to benefit. External validation and prospective evaluation are warranted.
Hyperbaric oxygen therapy (HBOT) enhances wound healing by promoting angiogenesis and reducing hypoxia. However, the role of air-breaks—intermittent exposures to ambient air during HBOT—remains unclear. We investigated the effects of air-breaks on HBOT-mediated wound healing, particularly in combination with adipose-derived stromal cells (ASCs). Full-thickness wounds were created in C57BL/6 mice (n = 36) and assigned to control, HBOT (1 h/day, 2 ATA for 11 days), or HBOT with a 10-min air-break groups. In a second experiment, we evaluated ASC treatment combined with HBOT and air-breaks. Wound healing was assessed via gross examination, histology and gene expression analysis of collagen type 1 alpha 1 (Col1a1), hypoxia-inducible factor 1 alpha (Hif1a) and tumour necrosis factor (Tnf-α). Compared with HBOT alone, air-breaks significantly improved wound closure, epithelial regeneration and collagen deposition (p < 0.05). Gene analysis showed higher Col1a1 expression and lower Hif1a and Tnf-α levels in the air-break group. In ASC-treated wounds, air-breaks further accelerated healing, enhancing collagen synthesis and reducing hypoxia and inflammation. These findings suggest that incorporating air-breaks into HBOT protocols improves wound healing outcomes, both generally and in ASC-based therapies, by modulating collagen production, hypoxia and inflammation, and could optimise HBOT efficacy, particularly in cell-based regenerative therapies.

DNA damage-induced by radiotherapy is a critical factor in promoting the death of colorectal cancer cells (CRC). Although high mobility group box 1 (HMGB1) reportedly plays a vital role in tumor radioresistance by modulating DNA damage repair, the precise mechanisms remain unclear. In this study, HMGB1 knockdown markedly enhanced cell apoptosis after radiation. HMGB1 downregulation significantly inhibited DNA damage repair and reactive oxygen species (ROS)-mediated redox homeostasis after irradiation in CRC cells. Mechanistically, HMGB1 interacts with KU70 via its region spanning residues 95–163. This interaction subsequently activates the non-homologous end joining (NHEJ) pathway to facilitate DNA damage repair, ultimately leading to reduced radiation-induced cell apoptosis. KU70 silencing showed the same effect as HMGB1 depletion mediated cell apoptosis and DNA damage response both in vitro and in vivo. Additionally, HMGB1 and KU70 were overexpressed in CRC tissues. Analysis of the GEPIA database indicated that elevated levels of both genes showed a trend toward association with poor patient prognosis, although this did not reach statistical significance. The current study revealed that HMGB1 may promote DNA damage repair through KU70 and its mediated NHEJ pathway to affect apoptosis in CRC cells after irradiation. Thus, targeting the HMGB1/KU70/NHEJ axis may be a potential therapeutic target to promote the response of CRC to radiotherapy and in-depth study of the specific mechanism of this axis in CRC radioresistance will help to the develop more effective treatment strategies.by Vu Nhi Ha, Le Chi Cao, Tran Hai Dang, Dao Thi Huyen, Nguyen Tien Dung, Le Huu Song, Nguyen Linh Toan, Truong Nhat My, Thirumalaisamy P.

BackgroundHepatitis E virus (HEV) causes sporadic outbreaks worldwide, with zoonotic and waterborne genotypes contributing to infections. In Vietnam, HEV genotypes 3 and 4 circulate among humans and swine, but data from remote, ethnic minority populations remain limited.
MethodsA cross-sectional study was conducted among 272 ethnic minority students at Thai Nguyen University of Medicine and Pharmacy (TUMP) to determine HEV infection markers and associated risk factors. Anti-HEV IgM and IgG were tested in serum samples using Wantai ELISA kits, and HEV RNA was detected by nested PCR targeting the ORF1 region. Demographic and exposure data were collected via structured questionnaires. Statistical analyses were performed using binary logistic regression.
ResultsOne participant (0.37%) tested positive for anti-HEV IgM, and 69 (25%) were positive for anti-HEV IgG, while HEV RNA was undetectable. HEV-IgG seroprevalence increased significantly with age (p = 0.004) but showed no sex-related differences. Consumption of tap or mixed water sources (p = 0.043) and raw or undercooked pork liver (p = 0.018) were significantly associated with HEV-IgG positivity. Multivariate analysis confirmed these factors as independent predictors of prior HEV exposure (adjusted OR = 1.6 and 4.8, respectively).
ConclusionsA moderate HEV seroprevalence among ethnic minorities indicates substantial prior exposure in northern Vietnam. Strengthening water sanitation, food safety awareness, and routine HEV surveillance is recommended to mitigate infection risk in vulnerable communities.

Background and aimsThe macronutrient composition of donor human milk (DHM) can vary substantially due to several factors such as maternal age, diet, and lactation duration. However, consistent macronutrient levels in DHM facilitate the administration of the required amounts to preterm infants. The current pooling strategy at most human milk banks combines milk from different batches from a single donor. This study aims to stabilize the macronutrient quality of DHM by pooling milk from different donors by utilizing machine learning prediction and optimisation techniques.
MethodsThe current pooling strategy is compared with a new theoretical approach that pools milk batches from up to 5 donors. To predict the crude protein and energy content, we used the following variables: body mass index, the donor’s diet (vegetarian or non-vegetarian), maternal age, full-term or preterm delivery, lactation stage, and volume pumped. These predictions are then used within an optimisation model to create milk pools that minimize the deviations from the target macronutrient levels (1.0 g protein/100 mL and 70 kcal/100 mL).
ResultsThe prediction model is based on 2236 created single-donor pools from 480 donors. Random forest regression models provided the most accurate predictions of macronutrient content. The new pooling strategy using multiple donors shows reduced deviations from target values compared to the current single-donor approach (average total absolute deviation 0.402 versus 0.664).
ConclusionThis study proves the potential of data-driven methods to improve operational efficiency in human milk banks, and improving the consistency of donor human milk.

Gastric cancer (GC) is one of the most common and lethal cancers globally. methyltransferase-like 3 (METTL3)-mediated N6-methyladenosine (m6A) RNA methylation plays a crucial role in tumor initiation and progression by regulating RNA function. STM2457, a highly efficient METTL3 inhibitor, can inhibit METTL3 activity and may serve as a potential therapeutic strategy in cancers. However, the role of STM2457 for GC cells is still unknown. In this study, we analyzed the expression profile data of GC in TCGA and GEO databases, and further explored the expression involvement of METTL3 in GC cell line, investigated the therapeutic effect of STM2457 targeted inhibition of METTL3 in GC both in vitro and in vivo experiments. The results indicated that STM2457 could suppress GC cell proliferation and migration by inhibiting METTL3, and also promoted cell apoptosis and arrest the cell cycle in S phase. In addition, STM2457 could inhibit tumor growth in subcutaneous xenotransplantation mouse model. Our findings suggested that STM2457 had great potential for the treatment of GC and could serve as a foundation for future clinical applications.
