This study was aimed at investigating the effects of demethylase fat mass and obesity-associated protein(FTO)and methyltransferase methyltransferase like protein 3(METTL3),key molecules in N6-methyladenosine(m6A)modification,on the replication and proliferation of Japanese encephalitis virus(JEV).Recombinant lentiviruses were generated by packaging the FTO and green fluorescent protein into lentiviral vectors.Neuro2a cells,a mouse neuroblastoma cell line,were infected with the lentivirus,and stable FTO-expressing cell lines were obtained through puromycin selection.Successful overexpression of FTO was confirmed through fluorescence microscopy,real-time quantitative PCR,and western blot analysis.When Neuro2a cells overexpressing FTO were infected with JEV,the overexpression of FTO decreased JEV replication in the cells,and increased the expression of interferon(IFN)and related molecules.Additionally,treatment of JEV-infected Neuro2a cells with the METTL3-specific inhibitor STM2457 resulted in a dose-dependent decrease in JEV replication and viral protein expression.These findings suggested that lowering m6A methylation levels inhibits JEV replication,thus shedding light on the regulatory role of methylation modification in JEV replication.

In recognition of the morbidity and mortality associated with human immunodeficiency virus (HIV), the Joint United Nations Programme on HIV/acquired immunodeficiency syndrome (AIDS) (UNAIDS) aims to end the epidemic by setting and striving to achieve the ambitious 95-95-95 targets. However, Singapore is still not performing well in the first UNAIDS target. The National HIV Programme (NHIVP) developed this set of recommendations based on an adaptation of major international guidelines from the World Health Organization and the US Centers for Disease Control and Prevention. The goals of this recommendation are: (1) to increase the uptake of HIV testing; (2) to allow earlier detection and identification of individuals with unrecognised HIV infection; (3) to facilitate linkage to clinical services; and (4) reduce further transmission of HIV infection in Singapore.

Background:
Adrenal venous sampling (AVS) is essential for diagnosing unilateral aldosterone oversecretion in primary aldosteronism (PA). Traditionally, AVS relies on radioimmunoassay (RIA) to measure plasma aldosterone concentration (PAC), although RIA has limited specificity and considerable variability. This study evaluated the role of liquid chromatography-tandem mass spectrometry (LC-MS/MS) in AVS and its impact on clinical outcomes.
Methods:
Among 230 patients with PA (May 2020 to April 2023) who underwent AVS, successful sampling was achieved in 182 patients (79.1%) under unstimulated conditions and 206 patients (89.6%) under stimulated conditions. PAC levels from peripheral and adrenal veins measured by LC-MS/MS were compared with RIA results. Patient outcomes were categorized according to the Primary Aldosteronism Surgical Outcomes criteria.
Results:
LC-MS/MS showed significant correlations with PAC levels measured by RIA in AVS (r=0.40 [unstimulated] and r=0.56 [stimulated]; both P<0.001). However, lateralization concordance between RIA and LC-MS/MS was moderate, at only 57.7% (unstimulated) and 64.6% (stimulated). LC-MS/MS identified more unilateral disease than RIA under both unstimulated (61.5% vs. 37.4%, P<0.001) and stimulated conditions (36.4% vs. 9.7%, P<0.001). Patients achieving complete clinical success after adrenalectomy were more accurately identified by LC-MS/MS than RIA under stimulated (55.6% vs. 22.2%, P=0.035), but not in unstimulated conditions.
Conclusion
LC-MS/MS outperformed RIA in identifying unilateral disease, resulting in higher rates of complete clinical success in adrenalectomy patients when surgical decisions were based on LC-MS/MS lateralization results.

Background:
The coronavirus disease 2019 (COVID-19) pandemic disrupted healthcare and worsened quality of life (QOL). Advanced esophageal cancer is often accompanied by malnutrition and poor QOL; chemoradiotherapy (CRT) remains the mainstay of treatment.We evaluated nutrition and QOL pre- and post-CRT immediately before and during the pandemic.
Methods:
Patients with esophageal cancer who underwent neoadjuvant or definitive CRT between April 2019 and December 2020 were enrolled. Disease severity, treatment timing, and outcomes were compared for cohorts treated pre-COVID-19 and during COVID-19. Nutritional status was measured with the Patient-Generated Subjective Global Assessment (PG-SGA). QOL was measured with the Mandarin Chinese version of the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and the esophageal site-specific module (QLQ-OES18). In the pandemic cohort, pre-/post-CRT paired analyses were performed.
Results:
Eighty-four patients were enrolled. The median diagnosis to treatment interval lengthened during COVID-19 (17.8 days vs. 24.2 days, p=0.04). Among the patients treated during the COVID-19 pandemic, nutritional status improved significantly following CRT (p=0.003). In the EORTC QLQ-C30, post-CRT scores for global health status (p<0.01) and emotional functioning (p<0.01) showed significant improvement. Additionally, symptom scores, including fatigue (p=0.02) and nausea and vomiting (p=0.02), decreased. However, financial difficulties worsened after CRT (p=0.02). In the EORTC QLQ-OES18, post-CRT symptom scores for eating (p<0.01), reflux (p=0.03), and pain (p<0.01) showed significant improvement.
Conclusion
Despite COVID-19-related delays, CRT enhanced nutrition, global health, and symptom control in esophageal cancer, although financial burdens increased. Integrating socioeconomic support with oncologic care is vital during health crises.

Background:
Rates of return to work (RTW) after an occupational injury vary considerably according to a range of factors. Limited studies have been conducted on the specific correlation between RTW and functional assessments, including activities of daily living (ADL) and instrumental activities of daily living (IADL). This prospective cohort study aims to determine if a relationship exists between ADL/IADL and RTW among injured workers in Taiwan.
Methods:
We recruited 162 workers who reported work-related injuries from January 2023 to May 2024. The assessment of ADL was evaluated using the Barthel Index, whereas IADL was evaluated using the Lawton Instrumental Activities of Daily Living scale. ADL/IADL were assessed immediately after the injury, at 3 and 6 months postinjury. Logistic regression models were used for the connections between ADL, IADL, and RTW while considering various confounding factors.
Results:
The mean ADL and IADL improved significantly at both 3 and 6 months postinjury. Logistic regression analysis indicated that IADL scores at 3 and 6 months postinjury were significantly linked to RTW. ADL scores lost significance after adjustment. Age was negatively associated with RTW, whereas sex and labor insurance status showed no significant association.
Conclusion
Short-term improvements in IADL are linked to successful RTW, rather than ADL for occupationally injured workers. Evaluations of IADL should be incorporated into rehabilitation plans to predict and improve RTW. Thorough rehabilitation approaches that address various aspects of functional abilities may be crucial to support successful RTW. Further studies are required to validate these results.

Objective:To explore the therapeutic mechanism of electroacupuncture(EA)in treating Parkinson disease(PD)using Tandem mass tag(TMT)quantitative proteomics technology. Methods:Forty-eight PD patients were randomly divided into a control group and an observation group,with 24 patients in each group.The control group received routine drug treatment,while the observation group received EA in addition to the routine drug treatment.EA was administered for 30 min per session,3 times a week,for a total of 12 weeks.Nine patients from each group were randomly selected to provide peripheral blood serum samples before and after treatment for TMT quantitative proteomics analysis.Differentially expressed proteins between the two groups were compared,and bioinformatics analysis was performed.The screened differentially expressed proteins were validated using enzyme-linked immunosorbent assay(ELISA). Results:In the observation group,scores on the unified Parkinson disease rating scale(UPDRS),UPDRS Ⅱ,and UPDRS Ⅲ were significantly reduced after treatment(P<0.05).In the control group,these scores tended to increase,but the changes were not statistically significant(P>0.05).After treatment,the UPDRS and UPDRS Ⅲ scores in the observation group were significantly lower than those in the control group(P<0.05).The observation group showed 62 differentially expressed proteins,while the control group had 36.Compared to the control group,the observation group had 142 differentially expressed proteins.These proteins were primarily involved in the cyclic adenosine monophosphate(cAMP)signaling pathway,T helper(Th)1 and Th2 cell differentiation,ATP-binding cassette transporter,vascular endothelial growth factor signaling pathway,and high-affinity immunoglobulin E receptor(FcεRI)signaling pathway.ELISA verification indicated that after EA treatment,the levels of α-Synuclein(αSyn)and heat shock protein beta 1(HSPB1)in the observation group were significantly lower than those in the control group(P<0.05),while the regulator of G-protein signaling 10(RGS10)level was significantly higher(P<0.05). Conclusion:EA,combined with routine drug therapy,can significantly improve clinical symptoms of PD,potentially through the regulation of the cAMP signaling pathway and the contents of differentially expressed proteins of αSyn,HSPB1,and RGS10.
