The increase in life expectancy and the rising number of people aged more than 50 years among people living with HIV (PLWH) both indicate an increasing risk of chronic non-communicable diseases, especially cardiovascular disease (CVD). Moreover, the contribution of traditional risk factors to CVD far outweighs that of HIV-related factors, which indicates that interventions for reducing CVD risk factors in PLWH are urgent.</p><p><strong>Methods: </strong>We designed a multicentre non-randomized controlled trial (nRCT), which incorporated six acquired immunodeficiency syndrome (AIDS)-designated hospitals in Zhejiang Province, and three rounds of surveys were conducted from January 2023 to January 2024. Assessments were performed at baseline, 3 months and 6 months post-intervention, respectively. For the intervention group, PLWH were informed of their 5/10-year CVD risk, on the basis of the assessment in baseline, verbally or online to warn them of the risk of having CVD; at the same time, personalized risky behaviour reinforcement intervention was implemented face-to-face or online for about 15 min. For the control group, PLWH were not informed of the 5/10-year CVD risk and only received routine health education in the clinic without additional intervention. Intervention effects were assessed using 5/10-year CVD risk, health-related behaviours (e.g., smoking, alcohol consumption, physical activities and dietary nutrition), as well as CVD cognitive level. To minimize baseline differences and reduce confounding due to non-treatment factors (e.g., socio-demographic characteristics), propensity score matching (PSM) was applied to construct comparable intervention and control groups, and a generalized estimating equation (GEE) was used to estimate the effect of the intervention. This trial was retrospectively registered with the Chinese Clinical Trial Registry (ChiCTR2500112178) on 11 November 2025.</p><p><strong>Results: </strong>A total of 948 PLWH were incorporated at baseline, after excluding ineligible participants, including 494 in the intervention group and 454 in the control group. The average age was 42.08 ( ± 11.94) years, with 826 male patients (87.13%). A total of 362 pairs were successfully matched after PSM. After matching, no statistical differences remained between the two groups. After 6 months' intervention, the intervention group showed significant improvements in CVD cognitive level, with a total increase of 2.30 points compared with 0.41 points in the control group (P = 0.028). Additionally, PLWH who almost never drink and have > 8 h of sedentary time per day, increased and decreased 4.54% and 1.46% respectively, compared with the control group (P < 0.05).

Increasing rates of resistance to conventional antibiotics have prompted the development of alternative therapeutic strategies capable of selectively targeting essential bacterial functions. Nucleic acid-based antimicrobial strategies have emerged as promising and precise approaches, enabling the inhibition of gene expression, suppression of virulence, restoration of antibiotic susceptibility, and inhibition of bacterial growth in a sequence-specific manner. This review investigates various studies on antisense oligonucleotides (ASOs), small RNA-based approaches, and CRISPR-Cas systems against S. aureus, with a focus on their antimicrobial efficacy, mechanisms of action, and delivery strategies. These platforms can target genes involved in cell division, transcription, quorum sensing, biofilm formation, and antibiotic resistance. As efficient intracellular delivery remains a major barrier, multiple carriers-including cell-penetrating peptides, nanoparticles, liposomes, DNA nanostructures, and phagemid-based platforms-have been developed to enhance therapeutic efficacy. It has been demonstrated that optimized delivery systems can substantially improve the stability, cellular uptake, and antibacterial activity of nucleic acid therapeutics. Furthermore, the programmability and high target specificity of these agents is a step forward, facilitating the development of precision antimicrobial therapies with the potential for reduced effects on non-target bacterial populations. Overall, the available data support the potential of nucleic acid-based antimicrobials as promising preclinical adjuncts to conventional antibiotics for combating multidrug-resistant S. aureus.</p>","PeriodicalId":13592,"journal":{"name":"Infectious Diseases and Therapy","volume":" ","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149037757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-adherence was attributable to inappropriate antibiotic selection in 22.9% of episodes and to an incorrect duration of antibiotic therapy in 25.6% of episodes.</p><p><strong>Conclusions: </strong>Paediatric GAS pharyngitis in this nationwide cohort was predominantly benign, with rare complications.
