HCV Self-testing in Malaysia

Self-testing with easy-to-use rapid diagnostic tests (RDTs) has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs and men who have sex with men. In Malaysia, HIV self-testing has been shown to have moderate to high levels of acceptability, depending on the population, test used, and test delivery framework. In the present study we aim to evaluate the acceptability and impact of an online program enabling home-based hepatitis C virus (HCV) self-testing in Malaysia.

HCV Self-testing in Georgia

Self-testing with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages.7 Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs (PWID) and men who have sex with men (MSM). In Georgia, HIV self-testing has been offered to MSM through an online platform promoting their uptake.11-12 In the present study aims to evaluate the acceptability and impact of using an online platform to enable home delivery of HCV self-testing in Georgia for PWID and MSM.

HCV Self-testing in Pakistan

To achieve the goal of elimination of hepatitis C infection in Pakistan, the strategy of elimination needs to be increasingly directed towards case finding through mass screening in rural or peri-urban communities to identify and treat those not yet aware of their infection. Self-testing (ST) with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. In the present study we aim to evaluate the acceptability and impact of a program enabling home delivery of hepatitis C virus (HCV) self-testing in the Malir district, Karachi division, Pakistan.

Evaluation Criteria, Diagnostic Criteria, Surgical Indications, and Establishment of Surgical Standards for "Cerebral Tinnitus Syndrome" Caused by Internal Jugular Vein Stenosis.

"Cerebral Tinnitus," also known as "cranial tinnitus," refers to the patient-reported perception of intracranial sounds. It often presents as "Cerebral Tinnitus Syndrome," which includes symptoms such as tinnitus with hearing loss, headaches, a heavy head sensation, blurred vision, neck and shoulder discomfort, sleep disturbances, anxiety, and depression. Due to limited awareness of cerebral tinnitus, patients frequently seek treatment across multiple facilities without success, severely impacting their and their families' lives and work. Xunming Ji and colleagues have pointed out that cerebral tinnitus results from stenosis of the cerebral or internal jugular veins (IJVS), which impairs cerebral venous outflow and the clearance of metabolic "waste," leading to chronic metabolic damage to brain cells. Currently, studies on the diagnosis and treatment of IJVS-induced cerebral tinnitus, both domestically and internationally, are primarily case reports, lacking systematic evaluation, diagnostic, and treatment standards, which significantly impacts patient outcomes. Our project team is the first to establish evaluation criteria, diagnostic standards, surgical indications, and surgical standards for "Cerebral Tinnitus Syndrome." In preliminary work, we performed internal jugular vein (IJV) decompression on 32 cerebral tinnitus patients, resulting in an IJV morphological improvement rate of 84.3%, a blood flow improvement rate of 75.0%, and a cerebral tinnitus syndrome improvement rate of 62.5%. To date, we have completed 88 IJV decompression surgeries, making ours the largest clinical center for such cases worldwide. We continue to refine these standards, notably introducing new intraoperative standards for IJV "release" and "high perfusion,". To validate and further study these standards, this project plans to perform IJV decompression surgery on 107 cerebral tinnitus patients affected by IJVS. We aim to establish a cerebral tinnitus database and develop a cerebral tinnitus evaluation scale to standardize evaluation criteria, diagnostic standards, surgical indications, and surgical standards, ultimately advancing clinical diagnosis and treatment of Cerebral Tinnitus Syndrome
