This study was aimed at understanding the relationships among the drug resistance and genome characteristics of group A Streptococcus in Jiangsu Province.A total of 149 group A Streptococcus strains were collected from hospitals between 2016 and 2023.Thirteen antimicrobial minimal inhibitory concentrations were detected with the micro-dilution broth method.The GAS strains were typed with emm genotyping analysis and whole genome sequencing,to determine the carriage rates of drug resistance genes and the evolutionary relationships among strains.The resistance rates of 149 GAS strains to erythromy-cin,tetracycline,and clindamycin exceeded 90％,whereas the strains showed sensitivity to 8 different antibiotics,including penicillin.Notably,the resistance rates to erythromycin,tetracycline,and clindamycin consistently increased over time.All strains were classified into 9 emm types,among which emm12 accounted for the highest proportion(77/149;51.68％).Signifi-cant statistical differences were observed among emm types,in terms of the drug resistance rate,number of resistant species,and prevalence of drug resistance genes.Furthermore,SNP evolutionary tree analysis revealed 3 distinct clusters within the GAS strains:emm12,emm1,and other emm types.emm 12 and emm1 were the dominant GAS strains in Jiangsu Province.Most isolates were resistant to erythromycin,tetracycline,and clindamycin.Differences in phenotypes and genomic characteris-tics were observed among emm types.

OBJECTIVES: To investigate the chain mediating role of family care and emotional management in the relationship between social support and anxiety among rural primary school students. METHODS: A questionnaire survey was conducted among students in grades 4 to 6 from four counties in Hunan Province. Data were collected using the Social Support Rating Scale, Family Care Index Scale, Emotional Intelligence Scale, and Generalized Anxiety Disorder -7. Logistic regression analysis was used to explore the influencing factors of anxiety symptoms. Mediation analysis was conducted to assess the chain mediating effects of family care and emotional management between social support and anxiety. RESULTS: A total of 4 141 questionnaires were distributed, with 3 874 valid responses (effective response rate: 93.55%). The prevalence rate of anxiety symptoms among these students was 9.32% (95%CI: 8.40%-10.23%). Significant differences were observed in the prevalence rates of anxiety symptoms among groups with different levels of social support, family functioning, and emotional management ability (P<0.05). The total indirect effect of social support on anxiety symptoms via family care and emotional management was significant (β=-0.137, 95%CI: -0.167 to -0.109), and the direct effect of social support on anxiety symptoms remained significant (P<0.05). Family care and emotional management served as significant chain mediators in the relationship between social support and anxiety symptoms (β=-0.025,95%CI:-0.032 to -0.018), accounting for 14.5% of the total effect. CONCLUSIONS Social support can directly affect anxiety symptoms among rural primary school students and can also indirectly influence anxiety symptoms through the chain mediating effects of family care and emotional management. These findings provide scientific evidence for the prevention of anxiety in primary school students from multiple perspectives.

OBJECTIVES: To evaluate and integrate evidence on the management of sleep disorders in children with attention deficit hyperactivity disorder (ADHD). METHODS: Literature was retrieved based on the 6S model, and evidence related to sleep disorder management in children with ADHD was extracted from the included references. RESULTS: A total of 17 studies were included, from which 16 pieces of evidence were extracted. Of these, 6 were classified as Level 1 evidence and 10 as Level 5. The evidence covered screening, assessment, non-pharmacological interventions, pharmacological interventions, follow-up, and multidisciplinary collaboration. CONCLUSIONS This study integrated evidence on the management of sleep disorders in children with ADHD using an evidence-based approach, providing an evidence-based foundation for managing sleep disorders in this population.

Environmental damage affects many aspects of healthcare, from extreme weather events to evolving population disease. Singapore's healthcare sector has the world's second highest healthcare emissions per capita, hampering the nation's pledge to reduce emissions by 2030 and achieve net zero emissions by 2050. In this review, we provide an overview of the impact environmental damage has on healthcare, including facilities, supply chain and human health, and examine measures to address healthcare's impact on the environment. Utilising the 'R's of sustainability - rethinking, reducing/refusing, reusing/repurposing/reprocessing, repairing, recycling and research - we have summarised the opportunities and challenges across medical disciplines. Awareness and advocacy to adopt strategies at institutional and individual levels is needed to revolutionise our environmental footprint and improve healthcare sustainability. By leveraging evidence from ongoing trials and integrating sustainable practices, our healthcare system can remain resilient against environment-driven challenges and evolving healthcare demands while minimising further impacts of environmental destruction.

INTRODUCTION: The primary objective of this guideline is to establish evidence-based recommendations for the clinical use of parenteral nutrition (PN) in adult patients within the acute hospital setting in Singapore. METHOD: An expert workgroup, consisting of healthcare practitioners actively involved in clinical nutrition support across all public health institutions, systematically evaluated existing evidence and addressed clinical questions relating to PN therapy. RESULTS: This clinical practice guideline developed 30 recommendations for PN therapy, which cover these key aspects related to PN use: indications, patient assess-ment, titration and formulation of PN bags, access routes and devices, and monitoring and management of PN-related complications. CONCLUSION This guideline provides recommendations to ensure appropriate and safe clinical practice of PN therapy in adult patients within the acute hospital setting.

Objective To investigate the effect of catalpol(CAT)on necrotic apoptosis in acute myocardial infarction(AMI)rats.Methods Rat AMI model was constructed by ligating the anterior descending branch of the left coronary artery.Sixty SPF grade SD male rats were randomly grouped into sham surgery group(Sham group),AMI model group(Model group),low-dose CAT group(CAT-L group,30 mg·kg-1 CAT),high-dose CAT group(CAT-H group,60 mg·kg-1 CAT),and high-dose CAT+RIP1 activator recombinant RIP1 group(CAT-H+rRIP1 group,60 mg·kg-1 CAT+8 μg·kg-1 rRIP1),12 in each group.CAT was administered by gavage once a day for a total of 4 weeks.Recombinant RIP1 was administered via tail vein injection and the next day for a total of 4 weeks.Sham group and Model group were given equal amounts of physiological saline by gavage and tail vein injection,respectively.The CAT-L group and CAT-H group were injected with physiological saline via the tail vein the next day while receiving gastric lavage.TUNEL staining was applied to observe the apoptosis of rat cardiomyocytes.Western Blot was applied to detect the expression of RIP1/RIP3/MLKL signaling pathway related proteins in rat myocardial tissue.Results The apoptosis rates of myocardial cells in the sham group,model group,CAT-L group,CAT-H group,and CAT-H+rRIP1 group were(4.23±0.63)％,(33.48±3.94)％,(13.50±1.86)％,and(29.62±3.08)％,respectively;the expression levels of RIP1 protein in myocardial tissue were 0.21±0.02,0.86±0.09,0.43±0.04,and 0.72±0.07,respectively;the expression levels of RIP3 protein were 0.30±0.03,0.94±0.09,0.49±0.05,and 0.83±0.08,respectively;the phosphorylation levels of MLKL protein were 0.35±0.04,1.13±0.11,0.64±0.06,and 0.97±0.10,respectively.The above indexes in Model group were compared with those in Sham group,and those in CAT-H group were compared with those in Model group and CAT-H+rRIP1 group,and the differences were statistically significant(all P＜0.05).Conclusion CAT may inhibit necrotic apoptosis of myocardial cells in AMI rats by down-regulating the RIP1/RIP3/MLKL signaling pathway.
