    BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine and reproductive condition affecting women of reproductive age, although its expression profiles and molecular pathways are not fully understood.

    AIMS: To identify the transcriptome expression profiles of peripheral blood mononuclear cells (PBMCs) in women with PCOS and controls. To investigate noninvasive diagnostic biomarkers and potential treatment targets to improve women's fertility.

    METHODS: RNA sequencing (RNA-Seq) was conducted on PBMC samples from six patients with PCOS and six healthy controls. qRT-PCR validation was carried out in 68 subjects. Multivariate logistic regression was performed to assess the combined impact of biomarkers.

    RESULTS: A total of 186 differentially expressed genes (DEG) were found between patients and controls (log2FC >1, p < 0.05). Enrichment analysis revealed cytokine-mediated signaling pathways, cytokine activity, and cytokine-cytokine receptor interaction. RNA sequencing showed consistency with qRT-PCR. Women with PCOS had significantly higher levels of AQP9 (p < 0.001), PROK2 (p = 0.001), and S100A12 (p < 0.001) expression compared to controls. AQP9 (AUC = 0.77), PROK2 (AUC = 0.71), and S100A12 (AUC = 0.82) adequately discriminated women with PCOS from healthy controls. In addition, multiple logistic regression on biomarkers resulted in a significant diagnostic power with an AUC = 0.89, 95 % CI: 0.81-0.97, p < 0.0001. Further associations were analyzed between relative gene expression and clinical, anthropometric, hormonal, and ultrasonographic data.

    CONCLUSIONS: Dysregulated RNA expression in PBMCs may contribute to an increased risk of PCOS and serve as a potential diagnostic biomarker. The involvement of inflammatory and cytokine-related pathways supports the notion that PCOS is a chronic inflammatory condition.

    AIMS: Evidence on the optimal targets of vancomycin for treating other Gram-positive infections apart from methicillin-resistant Staphylococcus aureus (MRSA) is lacking. This review aims to identify the recommended vancomycin therapeutic level for favourable clinical outcomes among patients infected with vancomycin-sensitive enterococcal infections.

    METHODS: Analytical studies describing the vancomycin levels of vancomycin-sensitive enterococcal infections among adult population were searched. The primary outcome was 30-day all-cause mortality, and the secondary outcomes were clinical failure and nephrotoxicity. Study characteristics were extracted and pooled using random-effects meta-analysis. The study quality was assessed using the Joanna Briggs Institute critical appraisal tool.

    RESULTS: A total of nine retrospective cohorts studies involving 1013 patients with vancomycin-sensitive enterococci were included. The meta-analysis found that high area under the curve to minimum inhibitory concentration ratio (AUC/MIC) of vancomycin ≥ 389 mg*h/L significantly lowered the 30-day mortality (odds ratio [OR], 0.44, 95% confidence interval [CI], 0.26-0.75). Analysis of the target AUC/MIC showed that high vancomycin AUC/MIC (≥ 389-400 mg*h/L) significantly reduced clinical failure rate (OR 0.59, 95% CI 0.37-0.94). The mortality and treatment failure rates did not differ significantly between those with high or low trough levels. Higher vancomycin AUC/MIC and trough levels were significantly associated with increased nephrotoxicity (OR 3.11, 95% CI 1.65-5.89; OR 2.95, 95% CI 1.60-5.44, respectively).

    CONCLUSIONS: The use of a higher vancomycin AUC/MIC concentration can be effective to reduce 30-day mortality and clinical failure but this needs to take into consideration the risk of nephrotoxicity. Well-conducted prospective studies are warranted due to the scarcity of evidence.

    The title racemic oxopyrrolidine compound, C13H17NO5, contains three stereogenic centres and crystallizes with two mol-ecules in the asymmetric unit. The five-membered pyrrolidine rings in both mol-ecules exhibit envelope conformations. The N-ethyl group of one of the mol-ecules is disordered over two sets of sites in a 0.836 (4):0.164 (4) ratio. In the crystal, both mol-ecules form inversion dimers through pairwise O-H⋯O hydrogen bonds, generating R 2 2(10) loops, which are linked into a three-dimensional network by weak C-H⋯O hydrogen bonds.

    The title compound, C5H4Cl2N2, crystallizes with one mol-ecule in the asymmetric unit. In the crystal, the mol-ecular entities are assembled through strong N-H⋯N hydrogen bonding, forming supra-molecular chains extending along the b-axis direction. These chains are inter-connected by offset π-π stacking inter-actions and consolidated by halogen-π inter-actions. The mol-ecular inter-actions were qu-anti-fied by Hirshfeld surface analysis, showing the significant contributions of Cl⋯H/H⋯Cl (40.1%), H⋯H (15.7%) and N⋯H / H⋯N (13.1%) inter-actions. Energy framework analysis using the CE-B3LYP/6-31 G(d,p) basis set revealed that Coulombic inter-actions make a considerable contribution to the total energy and crystal packing.

    Migraine is a common neurological disorder that presents considerable challenges to healthcare systems worldwide. These changes are especially relevant in rapidly developing regions such as Asia, with an increasingly productive population and ongoing advancements in healthcare systems and infrastructure. Despite its substantial impact, migraine management remains inadequate, potentially due to deficiencies in medical education. We hypothesized that significant gaps in basic and advanced medical training and continuing professional education contribute to the suboptimal management of migraine in various healthcare settings across Asia. A comprehensive literature review was conducted using PubMed and Google databases. The search focused on cross-sectional studies published in English from inception until September 2024 that examined educational needs among medical trainees and clinicians and clinical gaps in migraine management in Asia. These studies were then contextualized within a global perspective. The review identified significant shortcomings in migraine education at all levels of educational training in Asia, which also translated to poor management of migraines in clinical practice. Undergraduate medical curricula in Asia inadequately address headache disorders, while postgraduate training programs provide insufficient guidance in headache management, especially for complex cases. Primary care clinicians exhibited variable levels of understanding and frequently incorrectly diagnosed and managed migraine. Additionally, many Asian countries lack standardized clinical practice guidelines (CPGs) and specialized training programs for headache management. A multidimensional approach is required to tackle the pre-existing educational and clinical practice limitations. The approach should include improving the medical school curriculum, providing focused continuing medical education programs or developing migraine modules for primary care physicians (PCPs), and developing region-specific CPGs. Besides educational initiatives, integrating and coordinating systems of care, where primary and specialist services complement each other, are crucial for improving patient care. Robust education combined with comprehensive referral and linkage protocols ensures continuity of care across healthcare levels. Moreover, collaboration, communication, and cooperation among healthcare providers (HCPs) and organizations are vital to enhancing the quality of life and productivity of migraine patients in the region. A synergistic approach that combines robust collaboration with innovative educational delivery can catalyze the widespread adoption of evidence-based medicine (EBM).

    OBJECTIVE: The widespread penetration of the internet and digital technology have profoundly impacted the global economy and people's lives. Although the impact of digital skills on social development and personal lifestyles is well-documented, their influence on health and health inequalities remains underexplored. This study aims to analyze the impact of digital skills on health and health inequalities and to investigate the underlying mechanisms.

    METHODS: This study utilized cross-sectional data from the 2017 China General Social Survey (N = 2195). We employed the Ordered Probit (O-Probit) model and ordinary least squares regression to examine the impact of digital skills on health and explore the underlying mechanisms. Health inequalities across different groups were measured using the health concentration index.

    RESULTS: Enhancing digital skills enhances population health by boosting economic status, increasing social participation, and improving access to information. However, the impact varies by age and residence. Digital skills have a stronger effect on the health of young and middle-aged individuals, as well as urban residents, compared to older adults and rural populations. Furthermore, digital skills exacerbate health inequalities, benefiting high-income groups and widening the gap between income levels.

    CONCLUSIONS: Widespread promotion and continuous improvement of digital skills are key to enhancing public health. We need to focus on the popularization of digital skills and the construction of digital infrastructure for low-income disadvantaged groups and rural areas, as well as use various means to reduce group and regional differences in the impact of digital skills on health conditions.

    OBJECTIVE: This study aimed to assess the determinants of antenatal depression and its relation to intimate partner violence (IPV) among pregnant women at Hospital Melaka, Malaysia.

    METHODS: A cross-sectional study was conducted between February 1 and March 31, 2024, with 370 pregnant women recruited through convenience sampling. Inclusion criteria were Malaysian citizenship, age above 18 years, and ability to read and comprehend Malay. Data collection involved self-reported sociodemographic questionnaires, the Edinburgh Postnatal Depression Scale (EPDS), and the WHO Multicountry Study on Women's Health and Life Events Questionnaire.

    RESULTS: The prevalence of antenatal depression was 8.4%. IPV was reported by 64.1% of participants, with 54.6% experiencing controlling behavior, 30.0% emotional violence, 2.4% physical violence, and 3.5% sexual violence. Bivariate analysis showed that emotional violence (p < 0.001), physical violence (p < 0.001), sexual violence (p < 0.001), and hospitalization (p = 0.006) were significantly associated with an increased risk of antenatal depression. Multivariable logistic regression revealed that women receiving outpatient care had significantly lower odds of developing antenatal depression compared to hospitalized women (adjusted OR 0.262, 95% CI 0.100-0.683; p = 0.006). Women who experienced sexual violence were 18 times more likely to develop antenatal depression (adjusted OR 18.761, 95% CI 3.603-97.684; p < 0.001).

    CONCLUSION: The study highlights the need for healthcare workers to recognize risk factors for antenatal depression, particularly IPV.

    The initial assumption that viewed inclusion bodies as a hindrance to the efficient production of protein is no longer held due to the emergence of catalytically active inclusion bodies (CatIBs). Recent studies revealed their potential to be used in free form or immobilized as biocatalysts. The curiosity to acquire suitable catalysts has remained the measure of concern for researchers and industrialists. Numerous processes and production in various sectors of food industries, petroleum, pharmaceutical, cosmetics, and many others are still searching for a robust catalyst with outstanding features such as recyclability, resistance to pH, as well as temperature. CatIBs are forms of inclusion bodies that possess catalytic activity, which can improve catalysis efficiency, stability, and recyclability. One of the advantages of CatIBs is their potential to be used as catalysts for numerous bioprocesses when generated by an enzyme. These aggregates can efficiently be used as a replacement for traditional enzyme immobilization. This review tends to focus on the possibility of its application in various processes. The novelty of this review is that it considered the production of CatIBs both from artificial and natural perspectives, as well as how to improve it. Inclusion bodies' immobilization may provide an efficient alternative in the area of biocatalysis, and hence it will improve industrial sectors and substantially provide a means of achieving excellent performance in the near future.

    Asia remains vulnerable to new and emerging infectious diseases. Understanding how to improve next generation sequencing (NGS) use in pathogen surveillance is an urgent priority for regional health security. Here we developed a pathogen genomic surveillance assessment framework to assess capacity in low-resource settings in South and Southeast Asia. Data collected between June 2022 and March 2023 from 42 institutions in 13 countries showed pathogen genomics capacity exists, but use is limited and under-resourced. All countries had NGS capacity and seven countries had strategic plans integrating pathogen genomics into wider surveillance efforts. Several pathogens were prioritized for human surveillance, but NGS application to environmental and human-animal interface surveillance was limited. Barriers to NGS implementation include reliance on external funding, supply chain challenges, trained personnel shortages and limited quality assurance mechanisms. Coordinated efforts are required to support national planning, address capacity gaps, enhance quality assurance and facilitate data sharing for decision making.

    BACKGROUND: Abusive head trauma (AHT) is a leading cause of traumatic head injury in young children. This study estimated the annual direct medical cost of managing AHT at a single tertiary care centre in Malaysia.

    METHODS: Criteria were set for categorisation of patients as moderate or severe based on resource utilisation. The two methods used for cost computation were (1) cost estimation based on predefined clinical pathways for case management (2) computation of actual costs using patient-level data from retrospective review of all AHT admissions in 2021. Both methods utilised a combination of activity-based and top-down costing according to availability of reference data. Costs are presented in USD.

    RESULTS: Costs for 9 severe and 3 moderate cases in 2021 amounted to $70,532.16, of which 93 % was for severe cases. Cost estimate for moderate cases was $2009.88 while actual costs ranged between $749.37-3115.47 (median $1422.76). Cost estimates of $15,125.76-$17,958.18 for severe cases exceeded actual costs of $2195.57-$13,186.03 (median $7379.40) for severe cases due to shorter-than-expected duration of stay, with only 2 who underwent neurosurgical procedures. Major cost contributors were duration of stay, intensive care, ventilation and neurosurgical procedures.

    CONCLUSION: Cost comparison utilising predefined treatment standards versus actual patient data which reveals major cost determinants enables refinement of budget allocation. Median medical costs for severe cases which exceeded the monthly income ceilings of low- and middle-income households in Malaysia demonstrate the economic burden of AHT, reinforcing the need to invest in prevention.

    Edible bird's nest (EBN) is a functional food renowned for its numerous health benefits. While its nutritional and therapeutic value is well-documented, the metabolites contributing to the bioactivities of EBN remain poorly understood. This study aimed to identify the metabolites present in EBN subjected to different treatments, including double-boiled EBN (EBNdb), EBN hydrolysate (EBNhydro), EBN fermented with Lactobacillus helveticus (EBNLH), Latilactobacillus curvatus (EBNLC), and Latilactobacillus sakei (EBNLS) using liquid chromatography-mass spectrometry (LC-MS) and correlate the identified bioactive metabolites with the bioactivities of EBN. It was found that the fermented EBNs exhibited the highest number of metabolites, with 76 tentatively identified, followed by EBNhydro (45) and EBNdb (37). Citric acid (1.97-4.48 g/kg) was present in all treated EBN samples, while L(+)-lactic acid (3.03-8.07 g/kg) and adipic acid (2.33-3.18 g/kg) were only found in fermented EBNs. Among the treated EBN samples, EBNLC demonstrated the significantly highest (p ≤ 0.05) antioxidative (22.34 ± 0.41 % 1,1-diphenyl-2-picrylhydrazil radical scavenging activity), antihypertensive (5.46 ± 0.26 % angiotensin-converting enzyme inhibitory activity), and antihyperglycemic activities (6.48 ± 0.34 % α-amylase inhibitory activity). A total of 18 metabolites, including citric acid, 4-sphingenin, N-acetylcitrulline, 4-aminophenol, L(+)-lactic acid, 2-oxoadipate, sildenafil, formylglycinamidin-RP, 11β,17α,21-α-5β-pregnane-3,20-dione, 2-ketobutyric acid, homoserine, benzaldehyde, 1-pyrroline4-hydroxy-2-carboxylate, nortriptyline, 1-methylguanine, 3-hydroxy-trimethyllysine, 3-phenylpropionate, and reserphine were predicted as bioactive metabolites using the partial least squares discriminant analysis (PLS-DA). This study provides valuable insights into the metabolites present in EBN and serves as fundamental data for future investigations into the bioactive compounds responsible for its specific health benefits, potentially leading to the development of enhanced EBN-based functional foods.

    Under specific pretreatment or processing conditions, spheroprotein can be transformed into a molten globule state, a typical protein conformation with enhanced functionality. Analyzing the correlation between the formation of molten-globule structures and their quality and functional characteristics is critical for developing tailored processing features, especially for minimally processed future foods. This review outlines the mechanisms driving the formation of molten globule proteins through various processes including ultra-high pressure pretreatments, heating, ultrasonication, pH-shifting, macromolecular crowding and exposure to small-molecule denaturants. These treatments yield proteins that retain structural compactness and primary and secondary structures of their native forms, but with modified conformations and increased hydrophobicity. Common methods for characterizing molten globule proteins include fluorescence spectroscopy, circular dichroism spectroscopy, and nuclear magnetic resonance. The review also explores the application of molten globule proteins in food processing, highlighting their potential significance in advancing the field. The detailed elucidation and exploration of the microstructural transition and conformational features of molten globule proteins, together with their quantitative relationship with processibility of proteins from various sources, holds significant implications for optimizing protein-based food processing techniques and achieving targeted improvements in food quality.

    This study investigated the effects of pineapple peel powder with varied chemical profiles and sonication-assisted polyphenol biotransformation during fermentation on the quality characteristics of yogurt products. It aimed at exploring the feasibility of sonication-assisted fermentation to enhance the physicochemical properties, control post-acidification, and improve antioxidant activities in yogurts fortified with polyphenol-rich pineapple peel powder. Targeted analysis showed that polyphenol-rich pineapple dietary fiber obtained by ultrasonication-assisted extraction (NPFU) exhibited the slowest rates of acidification, highest antioxidant capacity, and lowest degree of whey separation at 21.67 %. Sonication pretreatments significantly increased transformation of free phenolic acids derived from pineapple peel fiber during fermentation, particularly increasing the accumulation of ferulic acid, caffeic acid and 5-hydroxyflavone, revealing the positive effects of sonication-mediated fermentation in promoting the hydrolysis of conjugated phenolics into free fractions. Yogurts fortified with pineapple peel fiber displayed significantly higher antioxidant activities (p

    BACKGROUND: Rice is subjected to various environmental stresses, resulting in significant production losses. Abiotic stresses, particularly drought and salinity, are the leading causes of plant damage worldwide. The High-affinity Potassium Transporter (HKT) gene family plays an important role in enhancing crop stress tolerance by regulating physiological and enzymatic functions.

    METHODS AND RESULTS: This study investigates the effect of overexpressing the rice HKT1;5 gene in Arabidopsis thaliana on its tolerance to salinity and drought. The OsHKT1;5 gene was introduced into Arabidopsis under the control of 35 S promoter of CaMV via floral dip transformation method. PCR confirmed the integration of the transgene into the Arabidopsis genome, while qPCR analysis showed its expression. Three transgenic lines of OsHKT1;5 were used for stress treatment and phenotypic studies. The overexpressed lines showed considerably higher germination rates, increased leaf counts, greater fresh and dry weights of the roots and shoots, higher chlorophyll contents, longer root lengths, and reduced Na+ levels together with increased K+ ions levels after salt and drought treatments, in comparison to wild-type plants. Furthermore, overexpressed lines exhibited higher antioxidant levels than wild-type plants under salinity and drought conditions. In addition, transgenic lines showed higher expression levels of the OsHKT1;5 gene in both roots and shoots compared to wild-type plants.

    CONCLUSIONS: In conclusion, this study revealed OsHKT1;5 as a promising candidate for enhancing tolerance to salinity and drought stresses in rice, marking a significant step toward developing a new rice variety with improved abiotic stress tolerance.

    In late 2017, Malaysia reported repeated outbreaks of low-pathogenic avian influenza virus (LPAI) H9N2 infections in commercial poultry flocks. Two H9N2 viruses, A/chicken/Malaysia/Negeri Sembilan/UPM994/2018 and A/chicken/Malaysia/Johore/UPM2033/2019, which were isolated from breeder and layer flocks in Peninsular Malaysia, were characterised in this study. Phylogenetic analysis revealed that both viruses were multiple-genotype reassortant strains with genes originating from Y280-like (HA gene), F/98-like (NS, NP and PA), G1-like (M and PB2), and Korean-like (PB1) lineages, indicating that they belong to a novel genotype that is divergent from the G57 lineage of Chinese origin. Both isolates were predicted to have a dibasic cleavage site (333-PSRSSRGLF-341) in the HA gene cleavage locations. Thus, the novel Malaysian H9N2 strain is a Y280-like virus resembling H9N2 isolates from Indonesia, Taiwan, Japan, and Cambodia. This virus is of the G57 lineage but has a novel genotype of the PB1 gene originating from a Korean-lineage H9N2 virus, which has not been detected before in the region.

    BACKGROUND: The capacity to anticipate future health issues is important for both policy makers and practitioners in the USA, as such insights can facilitate effective planning, investment, and implementation strategies. Forecasting trends in disease and injury burden is not only crucial for policy makers but also garners substantial interest from the general populace and leads to a better-informed public. Through the integration of new data sources, the refinement of methodologies, and the inclusion of additional causes, we have improved our previous forecasting efforts within the scope of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to produce forecasts at the state and national levels for the USA under various possible scenarios.

    METHODS: We developed a comprehensive framework for forecasting life expectancy, healthy life expectancy (HALE), cause-specific mortality, and disability-adjusted life-years (DALYs) due to 359 causes of disease and injury burden from 2022 to 2050 for the USA and all 50 states and Washington, DC. Using the GBD 2021 Future Health Scenarios modelling framework, we forecasted drivers of disease, demographic drivers, risk factors, temperature and particulate matter, mortality and years of life lost (YLL), population, and non-fatal burden. In addition to a reference scenario (representing the most probable future trajectory), we explored various future scenarios and their potential impacts over the next several decades on human health. These alternative scenarios comprised four risk elimination scenarios (including safer environment, improved behavioural and metabolic risks, improved childhood nutrition and vaccination, and a combined scenario) and three USA-specific scenarios based on risk exposure or attributable burden in the best-performing US states (improved high adult BMI and high fasting plasma glucose [FPG], improved smoking, and improved drug use [encompassing opioids, cocaine, amphetamine, and others]).

    FINDINGS: Life expectancy in the USA is projected to increase from 78·3 years (95% uncertainty interval 78·1-78·5) in 2022 to 79·9 years (79·5-80·2) in 2035, and to 80·4 years (79·8-81·0) in 2050 for all sexes combined. This increase is forecasted to be modest compared with that in other countries around the world, resulting in the USA declining in global rank over the 2022-50 forecasted period among the 204 countries and territories in GBD, from 49th to 66th. There is projected to be a decline in female life expectancy in West Virginia between 1990 and 2050, and little change in Arkansas and Oklahoma. Additionally, after 2023, we projected almost no change in female life expectancy in many states, notably in Oklahoma, South Dakota, Utah, Iowa, Maine, and Wisconsin. Female HALE is projected to decline between 1990 and 2050 in 20 states and to remain unchanged in three others. Drug use disorders and low back pain are projected to be the leading Level 3 causes of age-standardised DALYs in 2050. The age-standardised DALY rate due to drug use disorders is projected to increase considerably between 2022 and 2050 (19·5% [6·9-34·1]). Our combined risk elimination scenario shows that the USA could gain 3·8 additional years (3·6-4·0) of life expectancy and 4·1 additional years (3·9-4·3) of HALE in 2050 versus the reference scenario. Using our USA-specific scenarios, we forecasted that the USA could gain 0·4 additional years (0·3-0·6) of life expectancy and 0·6 additional years (0·5-0·8) of HALE in 2050 under the improved drug use scenario relative to the reference scenario. Life expectancy and HALE are likewise projected to be 0·4-0·5 years higher in 2050 under the improved adult BMI and FPG and improved smoking scenarios compared with the reference scenario. However, the increases in these scenarios would not substantially improve the USA's global ranking in 2050 (from 66th of 204 in life expectancy in the reference scenario to 63rd-64th in each of the three USA-specific scenarios), indicating that the USA's best-performing states are still lagging behind other countries in their rank throughout the forecasted period. Regardless, an estimated 12·4 million (11·3-13·5) deaths could be averted between 2022 and 2050 if the USA were to follow the combined scenario trajectory rather than the reference scenario. There would also be 1·4 million (0·7-2·2) fewer deaths over the 28-year forecasted period with improved adult BMI and FPG, 2·1 million (1·3-2·9) fewer deaths with improved exposure to smoking, and 1·2 million (0·9-1·5) fewer deaths with lower rates of drug use deaths.

    INTERPRETATION: Our findings highlight the alarming trajectory of health challenges in the USA, which, if left unaddressed, could lead to a reversal of the health progress made over the past three decades for some US states and a decline in global health standing for all states. The evidence from our alternative scenarios along with other published studies suggests that through collaborative, evidence-based strategies, there are opportunities to change the trajectory of health outcomes in the USA, such as by investing in scientific innovation, health-care access, preventive health care, risk exposure reduction, and education. Our forecasts clearly show that the time to act is now, as the future of the country's health and wellbeing-as well as its prosperity and leadership position in science and innovation-are at stake.
