While COVID-19 has become a global pandemic that has spread to all regions of the globe, local historic, health, and socio-environmental factors shape the epidemiological contours, response, and social challenges present within each affected nation. Thus, while countries like China, Italy, Iran, Brazil, and the United States have all been hard hit by the pandemic, there are critical differences across these nations in a number of variables (e.g. demographic features, health histories, healthcare systems, infection case rates, case fatality rates, national responses). In other words, within the global pandemic there are multiple importantly distinct national epidemics. Overcoming the grave threats to public health presented by COVID-19 requires both international cooperation and country-specific efforts that reflect local histories, needs, and resources. Already concerns are being expressed among health officials about how COVID-19 might be devastating in Africa. Currently, South Africa has the highest number of diagnosed COVID-19 cases on the continent and has been identified as being at high risk in the pandemic. This paper examines the public health response to the COVID-19 threat, how the prior and ongoing HIV and TB epidemics shape the COVID-19 epidemic and influence the response, and the potential ramifications of the response.Soft robotic devices can be used to demonstrate mechanics, robotics, and health care devices in classrooms. Zotatifin The complexity of soft robotic actuator fabrication has limited its classroom use. We propose a single-mold method of fabricating soluble insert actuators (SIAs) to simplify existing actuator fabrication methods using common accessible materials. This was accomplished by embedding molded soluble structures into curing polymer with custom molds and later dissolving the internal structure, leaving behind a hollow pneumatic network. Compared with similar actuators, SIAs actuated with comparable deformations while withstanding higher pressures for longer durations. SIAs have simple and accessible fabrication, resulting in durable actuators. We propose this method of actuator fabrication for use in K-12 schools to engage young students in this emerging field. In addition to silicone actuators, we show application of SIAs in biodegradable actuator fabrication, in a simplified model for classroom demonstration, and use in a glove designed to teach students the tactile art of ceramics.Abdominal aortic aneurysm (AAA) is life-threatening for which efficient non-surgical treatment strategy has not been available so far. Several previous studies investigating the therapeutic effect of mesenchymal stem cells (MSCs) in AAA indicated that MSCs could inhibit aneurysmal inflammatory responses and extracellular matrix (ECM) destruction, suppress aneurysm occurrence and expansion. Vascular smooth muscle cell (VSMC) phenotypic plasticity is reported to be predisposed in AAA initiation and progression. However, little is known about the effect of MSC on VSMC phenotypic modulation in AAA. In this study, we investigate the therapeutic efficacy of umbilical cord mesenchymal stem cells (UC-MSC) in elastase induced AAA model and evaluate the effect of UC-MSC on VSMC phenotypic regulation. We demonstrate that the intravenous injection of UC-MSC attenuate elastase induced aneurysmal expansion, reduce elastin degradation and fragmentation, inhibit MMPs and TNF-α expression, preserve and/or restore VSMC contractile phenotype in AAA. Taken together, these results highlight the therapeutic and VSMC phenotypic modulation effects of UC-MSC in AAA progression, which further indicates the potential of applying UC-MSC as an alternative treatment candidate for AAA.Background & aim Genetic variability in drug absorption, distribution, metabolism and excretion (ADME) genes contributes to the high heterogeneity of drug responses. The present study investigated polymorphisms of ADME genes frequencies and compared the findings with populations from other continents, available in the 1 KGP and ExAC databases. Methodology & results We conducted a study of 100 patients in Brazil and a total of 2003 SNPs were evaluated by targeted next-generation sequencing in 148 genes, including Phase I enzymes (n = 50), Phase II enzymes (n = 38) and drug transporters (n = 60). Overall, the distribution of minor allele frequency (MAF) suggests that the distribution of 2003 SNPs is similar between Brazilian cohort, 1000 Genome Project (1 KGP) and the Exome Aggregation Consortium (ExAC); however, we found moderate SNP allele-frequency divergence between Brazilian cohort and both 1000 KGP and ExAC. These differences were observed in several relevant genes including CYP3A4, NAT2 and SLCO1B1. Conclusion We concluded that the Brazilian population needs clinical assessment of drug treatment based on individual genotype rather than ethnicity.Introduction Focal choroidal excavation (FCE) is a concavity of the choroid detected on optical coherence tomography (OCT). It is usually idiopathic and the affected eyes are otherwise healthy with near-normal overlying retinal architecture and good visual acuity. Purpose To report a case of bilateral conforming FCE in the setting of Stargardt disease and inactive ocular toxoplasmosis. Case report A 20-year-old man with known history of Stargardt disease, healed toxoplasmosis, and high myopia presented to our ophthalmology department for follow-up examination and was found with bilateral FCEs not present in any of his previous examinations. Conclusion FCEs have been reported in the literature in otherwise healthy eyes as well as a broad spectrum of ocular diseases. The case herein reported Stargardt disease, toxoplasmosis, and high myopia all could potentially contribute to the pathogenesis of these findings. Further studies are needed to define etiologies as well as clinical significance and course of FCEs.The American Academy of Pediatrics provides guidance for pediatric primary care providers to promote healthy weight during childhood. Screening questions on diet and activity habits can help provider assessment and assist counseling for targeted behavior change. We implemented the parent completed, 10-item 5210 Healthy Habits Questionnaire (Ages 2-9 year) in our primary care practice serving low-income minority children with high rates of overweight and obesity. Adherence to the intervention protocol was high, and providers found the content and method of assessment useful for their counseling of individual patients. The aggregate Healthy Habits Questionnaire data provided a snapshot of the health habits in our local clinic population of children, prompting greater awareness for providers and informing their patient care.
