Acceptance and Factors Associated With Participation in Functional Cure–Related Trials Among People Living With HIV: A Cross-sectional Study in Southern China

HIV remains a global health challenge,and research efforts directed towards a functional cure require people living with HIV(PLHIV)in-volvement in clinical trials.Our study assessed willingness to participate in HIV functional cure–related clinical trials and associated fac-tors among PLHIV in Guangzhou,China,using a questionnaire survey approach.We analyzed responses from 718 questionnaires,finding that 71.2%were willing to participate in Phase Ⅲtrials,while 51.7%were willing to participate in Phase I trials and 42.9%expressed acceptability for analytic treatment interruption.Multivariate logistic regression demonstrated that male PLHIV,those with awareness of functional cure,and PLHIV,who had been on antiretroviral therapy(ART)for less than 1 year,were more willing to partic-ipate in Phase Ⅲtrials.Those with a body mass index greater than 24,and those without resistance to ART drug were more willing to participate in Phase I trials.The major motivations for participation in Phase Ⅲtrials were access to cutting-edge treatments(62.6%)and supporting research(55.3%).Safety was the main concern contributing to hesitancy.Our study revealed a high willingness to participate in HIV functional cure–related trials among PLHIV in Guangzhou,China,and willingness varied across different trial phases and was in-fluenced by multiple factors.This study provides valuable references for future clinical trial recruitment strategies and public health policy formulation.

Safety and Immunogenicity of SARS-CoV-2 Vaccines in People Living With HIV:A Systematic Review and Meta-analysis of Real-World Studies

The safety and immunogenicity of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)vaccines in people living with HIV(PLWH)in real-world studies remain controversial.Thus,we conducted a comprehensive systematic review and meta-analysis to address this issue.Data search were conducted from PubMed,Web of Science and EMBASE.Adverse events following vaccination,the risk ratio(RR)of SARS-CoV-2–specific IgG seroconversion and the level of anti–SARS-CoV-2 neutralizing antibodies were compared between the PLWH group and a healthy control group.A total of 10,582 PLWH from 22 studies were included.In our analysis,the incidence of local or systemic adverse events after the first SARS-CoV-2 vaccine dose was not statistically different between PLWH and healthy controls.However,there was a statistical difference after the second dose(RR,0.83;95%CI,0.71–0.98).The seroconversion rate of SARS-CoV-2 IgGantibodies in PLWH was significantly lower than that in the healthy control group(RR,0.94;95%CI,0.89–0.98;I2=80%,P<0.01).The anti–SARS-CoV-2 neutralizing antibody titers in PLWH after full immunization were also significantly lower than those in the healthy control group(RR,0.91;95%CI,0.85–0.98;I2=81%,P<0.01).The safety and tolerance of COVID-19 vaccines in PLWHare acceptable.However,their immunogenicitymay be impaired to a certain extent,characterized by a lower IgGseroconversion rate and neutralizing antibody titers compared with healthy individuals.These findings should provide guidance for optimizing future COVID-19 vaccination strategies among PLWH.

A Large Acute Gastroenteritis Outbreak Associated with Both Campylobacter coli and Human Sapovirus—Beijing Municipality,China,2021

What is already known about this topic?Campylobacter is a significant foodborne pathogen that leads to global outbreaks of acute gastroenteritis(AGE)usually affecting less than 30 individuals.Human sapovirus(HuSaV)is an enteric virus responsible for sporadic cases and outbreaks of AGE worldwide.In a study conducted in Beijing,HuSaV detection ranked second after norovirus.What is added by this report?We present a discussion of the first large-scale outbreak of AGE caused by both Campylobacter coli(C.coli)and HuSaV.The outbreak involved a total of 996 patients and exhibited two distinct peaks over a period of 17 days.Through case-control studies,we identified exposure to raw water from a secondary water supply system as a significant risk factor.Among 83 patients,49 samples tested positive for C.coli,39 samples tested positive for HuSaV,and 27 samples tested positive for both pathogens using real-time polymerase chain reaction detection.Furthermore,whole-genome sequencing of 17 C.coli isolates obtained from 17 patients revealed that all isolates belonged to a highly clonal strain of C.coli.What are the implications for public health practice?Outbreaks of AGE resulting from multiple pathogen infections warrant increased attention.This report emphasizes the significance of ensuring the safety of drinking water,particularly in secondary supply systems.

Dichloromethane-Induced Poisoning from Acrylic Paint Cleaner-Shenzhen City,Guangdong Province,China,2023

Summary What is already known about this topic?Dichloromethane(DCM)is a colorless and transparent organic solvent that commonly causes poisoning during occupational contact.What is added by this report?Unknown to teachers and students,they were utilizing an acrylic paint cleaner that contained DCM.At the time of the poisoning incident,the art room was occupied beyond its capacity with inadequate local ventilation.The primary cause of the incident was determined to be the students’inhalation of DCM during the cleaning process.What are the implications for public health practice?The unclear composition of environmental cleaning products available for purchase online presents a major obstacle for consumers trying to assess their toxicity.It is imperative that robust regulatory measures and proactive public education campaigns are implemented to mitigate instances of poisoning.
