Veterans are approximately 30% more likely than non-veterans to suffer from severe hearing impairment. Tinnitus, or ringing in the ears, which is increasingly common among military service men and women, has been linked to significant cognitive and psychological impairment and can be worsened by the same sounds that trigger post-traumatic stress disorder (PTSD). In fact, tinnitus and PTSD often present as comorbidities, and recent studies suggest these two disorders may share a common neurological pathway. Additional studies are required to better understand the connection between hearing loss and impaired cognitive function such as that observed in with PTSD. Here, we use the fruit fly, Drosophila melanogaster, to explore the relationship between hearing loss and cognitive function. Negative geotaxis climbing assays and courtship behavior analysis were used to examine neurobehavioral changes induced by prolonged, intense auditory stimulation. Preliminary results suggest that exposure to loud noise for an extended period of time significantly affected Drosophila behavior, with males being more sensitive than females. Based on our results, there appears to be a potential connection between noise exposure and behavior, further suggesting that Drosophila could be an effective model to study the link between hearing loss and PTSD.
The ongoing Global Coronavirus Pandemic has been upheaving social norms for over a<br/>year at this point. For countless people, our lives look very different at this point in time<br/>then they did before the pandemic began. Quarantine, Shelter in Place, Work from<br/>Home, and Online classes have led global populations to become less active leading to<br/>an increase in sedentary lifestyles. The final impact of this consequence is unknown,<br/>but emerging studies have led to concrete evidence of decreased physical and mental<br/>wellbeing, particularly in children. VirusFreeSports was the brainchild of three ASU<br/>Honors students who sought to remedy these devastating consequences by creating<br/>environments where children can participate in sports and exercise safely, free of the<br/>threat COVID-19 or other transmissible illnesses. The ultimate goal for the project team<br/>was to build traction for their idea, which culminated in a video pitch sent to potential<br/>investors. Although largely created as an exercise and we did not create a full<br/>certification course, merely a prototype through a website with sample questions to<br/>gauge interest, the project was a success as a large target market for this product was<br/>identified that showed great promise. Our team believes that early entrance to the<br/>market, as well as the lack of any other competitors would give the team a tremendous<br/>advantage in creating an impactful and influential service.
Background: Recent studies have shown a decline in birth rates in large metropolitan areas (after accounting for population), which can be possibly explained by barriers to reproduction associated with the COVID-19 pandemic and related lockdowns. Objective: This study’s objective was to investigate the impact of the COVID-19 pandemic and related lockdowns on the fertility rates of women in reproductive ages living in Greater Phoenix. Methods: The total number of inpatient births and people in both Maricopa and Pinal Counties during pre-COVID-19 years (2017-2019) were compared with those during the COVID-19 years (2021) among women in reproductive ages (15-49 years). To make age-specific comparisons, women in reproductive years were divided into eight distinct age group categories (15-17, 18-20, and then five year age group categories to age 49) from which age-specific, general, and total fertility rates were calculated. Results: Using a two-sample z-test for difference in proportions, findings revealed that the general fertility rate in Greater Phoenix had significantly declined from 48 to 46 per 1,000 population from the pre-COVID-19 period to COVID-19 period (P<0.001). Two sample z-tests were also used to compare age-specific fertility rates, which revealed a significant decline in the fertility rate in women ages 15-17 (from 8.0/1000 to 5.0/1000) (P<0.001), 18-20 (from 43.0/1000 to 35.0/1000) (P<0.001), and 21-24 (from 79.0/1000 to 68.0/1000) (P<0.001) from the pre-COVID-19 period to COVID-19 period, while no significant change was observed in the fertility rate in women ages 25-49. Conclusions: The observed general fertility decline in Greater Phoenix as a result of the COVID-19 pandemic poses significant implications for further research on barriers to reproduction brought upon by the COVID-19 pandemic and related lockdown measures. Another direction for further research involves possibly continuing this study to include years 2022 and 2023 in the COVID-19 period, as well as calculating age-specific fertility rates by race.
In late 2019, COVID-19, a new disease caused by a novel (or new) coronavirus began to take over the lives of many people. This study centers on how members of the Latinx community have been affected by COVID-19. Both quantitative and qualitative data were utilized to analyze the perceived risk of infection, preventative behaviors, and acceptability of the COVID-19 vaccine for individuals that identify as Latinx. Analysis of the survey and interview analysis found the majority of participants expressed abiding by recommended measures and becoming hypervigilant about their activities, and their desire to get vaccinated against COVID-19 when they are eligible. Individuals who did not express the desire to be vaccinated mentioned worries including side effects, costs, safety, and efficacy of the vaccine. Results from this research could aid in the creation of public health initiatives in order to increase the uptake of the vaccine tailored for the Latinx community.
