Voice biomarkers， as an emerging smart medical technology， are now being used in applications such as assisting in the diagnosis and treatment of diseases， facilitating accurate and personalized medical services for patients. However， it also raises many ethical issues， including informed consent， privacy protection， accuracy and reliability， data security， legal risks， and other issues. This paper systematically sorted out the ethical issues in the applications of voice biomarkers in the medical field， summarized these issues， such as informed consent， privacy protection， accuracy and reliability， data security， and legal risks， as well as explored the corresponding coping strategies. These countermeasures encompassed utilizing new media platforms to raise public awareness of voice biomarkers， strengthening supervision and management to promote the privacy protection of voice biomarkers， reducing algorithm biases to promote the general benefits of voice biomarkers to the public， establishing multidisciplinary teams to protect the data security of voice biomarkers， and encouraging medical professionals and researchers to participate in policy research， with a view to providing references for promoting and regulating the applications of voice biomarkers in the medical field.

Objective To systematically evaluate and integrate the experiences of people living with HIV in peer support,and to provide references and suggestions for improving peer support for HIV patients in clinical practice.Methods The computer retrieval was performed in PubMed,CINAHL(EBSCO),Web of Science,ProQuest,CNKI and Wanfang Data from January 1,1996 to September 30,2022,to collect qualitative studies in the experience of people living with HIV participating in peer support.This qualitative systematic review was conducted under the Joanna Briggs Institute guideline.This paper was written according to the enhancing transparency in reporting the synthesis of qualitative research(ENTREQ).Results A total of 7 qualitative studies were included,and 26 findings were extracted,which were summarized into 12 categories and integrated into 4 synthesized findings.Findings included that peer support provides patients with information and help them establish and maintain a healthy lifestyle;patients receive emotional support in peer support;patients receive instrumental support in peer support;the objective requirements and scenarios of peer support.Conclusion AIDS peer support has a positive effect on AIDS prevention and treatment,and it is important to address the practical needs of people living with HIV/AIDS.The practice of HIV peer support needs further theoretical support and scientific guidance.Building an HIV peer support model,providing systematic training and professional guidance to HIV peers is conducive to improving the accuracy of HIV peer support behaviors,the development of HIV peer support activities,and optimizing the effectiveness and sustainability of peer support for people living with HIV/AIDS.
