Virtual Implementation of a Photovoice Project With Youth in Baltimore During the COVID-19 Pandemic
This article describes the virtual implementation of Photovoice activities conducted as part of a project that sought to gather youthsâ perspectives on neighborhood and housing conditions, community redevelopment, and health and well-being in Baltimore. We discuss the original in-person design and how activities were implemented virtually, in light of coronavirus disease 2019 (COVID-19) physical distancing guidelines. Challenges to virtual implementation included establishing rapport with youth and families during recruitment and data collection, encouraging active participation during discussion sessions, and varying technological skills among youth. Facilitators of virtual implementation included partnering with a community organization, piloting virtual sessions to assess participantâs technology skills, and providing various ways for youth to participate during discussion sessions, engage in group activities, and receive hands-on instruction. This article showcases the ways in which virtual implementation of Photovoice activities can be successfully implemented with youth and provides recommendations for future Photovoice projects that include virtual activities
Association of Glomerular Filtration Rate with High-Sensitivity Cardiac Troponin T in a Community-Based Population Study in Beijing
BACKGROUND: Reduced renal function is an independent risk factor for cardiovascular disease mortality, and persistently elevated cardiac troponin T (cTnT) is frequently observed in patients with end-stage renal disease. In the general population the relationship between renal function and cTnT levels may not be clear because of the low sensitivity of the assay. In this study, we investigated the level of cTnT using a highly sensitive assay (hs-cTnT) and evaluated the association of estimated glomerular filtration rate (eGFR) with detectable hs-cTnT levels in a community-based population. METHODS: The serum hs-cTnT levels were measured in 1365 community dwelling population aged â„45 years in Beijing, China. eGFR was determined by the Chinese modifying modification of diet in renal disease (C-MDRD) equation. RESULTS: With the highly sensitive assay, cTnT levels were detectable (â„3pg/mL) in 744 subjects (54.5%). The result showed that eGFR was associated with Log hs-cTnT (râ=â-0.14, P<0.001). After adjustment for the high predicted Framingham Coronary Heart Disease (CHD) risk (10-year risk >20%) and other prognostic indicators, moderate to severe reduced eGFR was independently associated with detectable hs-cTnT, whereas normal to mildly reduced eGFR was not independently associated with detectable hs-cTnT. In addition, after adjustment for other risk factors, the high predicted Framingham CHD risk was associated with detectable hs-cTnT in the subjects with different quartile levels of eGFR. CONCLUSION: The levels of hs-cTnT are detectable in a community-based Chinese population and low eGFR is associated with detectable hs-cTnT. Moreover, eGFR and high predicted Framingham CHD risk are associated with detectable hs-cTnT in subjects with moderate-to-severe reduced renal function
The auditory cortex of the bat Phyllostomus discolor: Localization and organization of basic response properties
<p>Abstract</p> <p>Background</p> <p>The mammalian auditory cortex can be subdivided into various fields characterized by neurophysiological and neuroarchitectural properties and by connections with different nuclei of the thalamus. Besides the primary auditory cortex, echolocating bats have cortical fields for the processing of temporal and spectral features of the echolocation pulses. This paper reports on location, neuroarchitecture and basic functional organization of the auditory cortex of the microchiropteran bat <it>Phyllostomus discolor </it>(family: Phyllostomidae).</p> <p>Results</p> <p>The auditory cortical area of <it>P. discolor </it>is located at parieto-temporal portions of the neocortex. It covers a rostro-caudal range of about 4800 ÎŒm and a medio-lateral distance of about 7000 ÎŒm on the flattened cortical surface.</p> <p>The auditory cortices of ten adult <it>P. discolor </it>were electrophysiologically mapped in detail. Responses of 849 units (single neurons and neuronal clusters up to three neurons) to pure tone stimulation were recorded extracellularly. Cortical units were characterized and classified depending on their response properties such as best frequency, auditory threshold, first spike latency, response duration, width and shape of the frequency response area and binaural interactions.</p> <p>Based on neurophysiological and neuroanatomical criteria, the auditory cortex of <it>P. discolor </it>could be subdivided into anterior and posterior ventral fields and anterior and posterior dorsal fields. The representation of response properties within the different auditory cortical fields was analyzed in detail. The two ventral fields were distinguished by their tonotopic organization with opposing frequency gradients. The dorsal cortical fields were not tonotopically organized but contained neurons that were responsive to high frequencies only.</p> <p>Conclusion</p> <p>The auditory cortex of <it>P. discolor </it>resembles the auditory cortex of other phyllostomid bats in size and basic functional organization. The tonotopically organized posterior ventral field might represent the primary auditory cortex and the tonotopically organized anterior ventral field seems to be similar to the anterior auditory field of other mammals. As most energy of the echolocation pulse of <it>P. discolor </it>is contained in the high-frequency range, the non-tonotopically organized high-frequency dorsal region seems to be particularly important for echolocation.</p
Insomnia, Health-Related Quality of Life and Healthcare Resource Consumption: A Study of Managed-Care Organisation Enrollees
Objective: Insomnia is a prevalent sleep complaint which has been reported to be greatly associated with reduced health-related quality of life (HR-QOL) and increased healthcare resource use. This study documents the prevalence of insomnia, and its impact on patients' HR-QOL and healthcare resource use in managed-care settings in the US. Design and Setting: A multi-site survey of 5 American Medical Group Association(R) (AMGA) clinics was conducted. Each clinic mailed questionnaires to 1100 randomly selected individuals enrolled in its healthcare system and distributed questionnaires to 400 individuals during a clinic visit and prior to seeing a physician. The questionnaire was a form of the Health Status Questionnaire with the well-validated Medical Outcomes Study 36-Item Short Form (SF-36) Health Survey, a 3-question depression screen, a sleep questionnaire, demographic variables, and questions about medical encounters and prescription and over-the-counter (OTC) drug use. Main outcome measures and results: Approximately one-third of managed-care enrollees in this study reported insomnia with daytime dysfunction. Individuals with insomnia reported lower HR-QOL scores and increased healthcare resource use compared with individuals with no insomnia. After controlling for demographic variables and comorbid conditions, the negative association of insomnia remained significant on all HR-QOL scores, emergency room visits, calls to the physician and OTC drug use. Conclusions: Insomnia is significantly associated with reduced HR-QOL and increased healthcare resource use in enrollees of managed-care organisations.Pharmacoeconomics, Quality-of-life, Resource-use, Insomnia, Quality-of-life-rating-scales, Sleep-disorder-therapies
