To reduce its heavy burden on the healthcare system, prevention-based public health policies targeting CVD become the focus through promoting healthy behaviors and managing risk factors, as well as reducing health disparities with improved access to care for vulnerable populations. However, with limited data from the long-term large-scale population studies, public health practitioners and policymakers can't assess the cost and effectiveness of policy implementation well. Instead, microsimulation model (MSM) has been employed as a powerful tool to analyze the public health policy. In our project, we adapted the well-established and validated MSM (CVD Policy Model) for tobacco tax policy analysis in New York city with incorporation of 2 key factors: 1) illicit market and 2) secondhand smoke exposure. We simulated each individual's CVD (e.g., stroke and coronary heart disease) trajectory, and estimated the associated health cost reduction and the quality-adjusted life years (QALYs) gained by implementing tax policy to reduce cigarette consumption and secondhand smoke exposure for adults in NYC. In the model, the population socioeconomical and health profiles were sampled from NYC Health and Nutrition Examination Survey dataset and the relative risk of secondhand smoke exposure on CVD were pooled from the recent meta-analyses. Our preliminary results show that the additional tobacco tax can be cost-effective (defined as <$50,000 per QALY) even with substantial illicit market. Benefits from nonsmokers exposed to secondhand smoke shouldn't be ignored in the analysis which contributes over 27% of total incremental QALYs. On the Structure-Function Relationships of the Mouse Common Peroneal Nerve for Bioelectronic Pain Management in Joint Disorders Peter Zoss (Matthew Ward, advisor) [cid:image008.jpg@01D9C55E.9993AC90] Abstract: Arthritis is a common joint disorder that causes pain, swelling, and stiffness. An estimated 24% of adults in the US have some form of arthritis, including rheumatoid arthritis, osteoarthritis (OA), and posttraumatic osteoarthritis (PTOA), where the joint degenerates more rapidly following an injury. Arthritis has no cure, with pain being the most prominent and persistent symptom. Current management techniques for PTOA rely heavily on pharmaceutical approaches such as anti-inflammatory and painkiller medications, each with their own side effects and complications. Novel effective and durable intervention techniques are necessary. My research explores the structure-function relationship of nerves that supply the murine knee. My primary aim is to identify the morphology and extracellular signaling characteristics of the nerve fibers that transmit pain-related information to the central nervous system (CNS) in a PTOA model. MicroLeads cuff electrodes with 130 µm inner diameters and 0.15 mm spacing between the two platinum plated leads were implanted in the hindlimbs of 8 C57BL/6J mice to record and stimulate the common peroneal nerve, a branch of the sciatic nerve that is responsible for the sensation to portions of the leg and knee joint. Single-ended recordings from multiple cuff electrode leads showed spontaneous and evoked SFAP activity and allowed for the discrimination of afferent (sensory) and efferent (motor) activity. ECAP signals were then collected with bipolar cuff electrodes in response to a variety of stimulus parameters, giving insight into the composition of the nerve and providing a basis for feedback-controlled stimulation targeted to pain-related fibers. Targeted stimulation is key in neural-based interventions as only unmyelinated C fibers and A-delta fibers carry pain signals. These results show the potential for a targeted feedback-controlled system of peripheral nerve activity, which could lead to personalized PTOA management devices that are responsive to individual pain management needs. *Join Zoom Meeting https://purdue-edu.zoom.us/j/98231659969?pwd=T21Oa1B6QzFyQzFvckMzS1doNGlJUT09<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpurdue-edu.zoom.us%2Fj%2F98231659969%3Fpwd%3DT21Oa1B6QzFyQzFvckMzS1doNGlJUT09&data=05%7C01%7Cbmeroundtable-list%40ecn.purdue.edu%7Ca61a537f22b34c82baf408db94283509%7C4130bd397c53419cb1e58758d6d63f21%7C0%7C0%7C638266672623417241%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=nptVqGZmKIIVyKQHgw0BAJbuvtl0lto5dILwMIdTqAc%3D&reserved=0> Meeting ID: 982 3165 9969 Passcode: biomedical -- Bmeroundtable-list mailing list Bmeroundtable-list@ecn.purdue.edu https://engineering.purdue.edu/ECN/mailman/listinfo/bmeroundtable-list
