Compliance-free Class II correction and its relationship to vertical facial characteristics

Background: While efficacy of the Forsus appliance has been shown, there are disagreements on its mechanism for Class II correction. Class II studies have been criticized for ignoring potential differences in results based on differing vertical facial phenotypes. The purpose of this study was to better understand the effects of Class II correction using the Forsus appliance and relate changes during and at the completion of treatment to initial MP-SN angles. Materials and Methods: Records of 59 patients obtained at 4 different time points were examined retrospectively. ANOVA was used to describe the cephalometric changes and Pearson’s correlation tested for any relationship between patients’ pretreatment MP-SN angle and other selected measures. Results/Conclusions: Class II correction was achieved by mesial movement of the mandibular dentition, differential mandibular growth, and clockwise rotation of the occlusal plane. There was no correlation between pre-treatment MP-SN angles and any selected cephalometric measure

Lessons Learned from Missouri Institutions of Higher Education Response to the COVID-19 Pandemic

Institutions of higher education (IHE) have worked tirelessly to mitigate the effect of SARS-Co-V2 (COVID-19) on their campuses. Shortly after COVID-19 hit Missouri, several state departments united their efforts to understand and problem-solve around the pandemic. The Missouri Department of Higher Education and Workforce Development (DHEWD) led one such effort, facilitating weekly meetings with members from Missouri’s IHE. The research team reviewed thirty-one video recordings from November 4, 2020, to June 9, 2021, and interviewed DHEWD staff. Using focused coding, the research team identified the role of DHEWD, leaders that emerged during the process, several challenges IHE faced during the pandemic, and successes and accomplishments. IHE were also challenged by how to mandate or incentivize the vaccine, and new human resources policies that emerged as a result of an increase in remote work schedules. This research highlights the importance of continued collaboration among IHE and various state departments, an intentional relationship between public health and IHE, and an increased investment in mental health services in order to prepare for the next public health emergency

Program Evaluation of Cyber Senior Program

Cyber Seniors is a community-based intervention focusing on improving skills and knowledge around technology for senior citizens in the community. The program uses college students as educators and mentors to help the seniors build relationships and increase social connectedness while reducing social isolation. Through our program evaluation class, we reviewed the program and identified areas of success and areas we can improve on for future Cyber Senior programs. We did this by gathering both qualitative and quantitative data, allowing us to identify the needs that were met and what still needs to change. This program has opportunities for both students and senior citizens to grow while also teaching all of us valuable life skills

Relationships of eating competence, sleep behaviors and quality, and overweight status among college students

Little is known about the relationships between eating competence (intra-individual approach to eating and food-related attitudes and behaviors that entrain positive bio-psychosocial outcomes) and sleep behaviors and quality in college students, a high-risk group for poor eating habits, weight gain, and inadequate sleep. Thus, data from full-time college students (N = 1035; 82% White; 61% female) aged 18–24 years from 5 U.S. universities were obtained from online questionnaires (eating competence (ecSI), Pittsburg Sleep Quality Index (PSQI), physical activity, demographics) and physical assessments (measured height, weight), to explore sleep behavior and quality between eating-competent (EC; ecSI score ≥ 32) and non-EC groups (ecSI \u3c 32). Generalized linear models controlling for gender, body mass index, and physical activity were utilized. A higher proportion of those in the EC group reported adequate sleep quality (67% vs. 57% in non-EC, p = 0.001), sleep duration of ≥ 7 h nightly (58% vs. 50% in non-EC, p = 0.007), and infrequent daytime dysfunction (72% vs. 65% in non-EC, p = 0.02). When ecSI scores were grouped as tertiles, those in the highest tertile reported a higher prevalence of no sleep disturbances (7% vs. 2% in the lowest ecSI tertile, p = 0.006) and lower prevalence of sleep medication use (10% vs. 15% in the lowest ecSI tertile, p = 0.04). Results suggest that competent eaters are more likely to have better overall sleep quality and fewer sleep-related issuescompared to less competent eaters. These findings may inform future longitudinal studies, and health promotion and weight management interventions for young adults

Emergency Medicine in the Time of COVID

The novelty and uncertainty associated with COVID-19 has created challenges for politicians, citizens, and healthcare providers, leaving no one unaffected. As members of the front line of defense, providers in Emergency Departments (EDs) face the momentous challenge of effectively identifying and treating patients with COVID-19, working with experts in Infectious Disease, Internal Medicine, Critical Care, Public Health, and others. We must coordinate these efforts while also protecting staff, implementing strategies to reduce transmission, and managing ED patients with conditions unrelated to COVID-19. Striving to maintain a grasp of the rapidly accumulating publications in medical journals and the media, we provide this brief article as a pragmatic summary of the challenges facing the ED

Hand-portable gas chromatography-ion mobility spectrometer for the determination of the freshness of fish

A hand-held, portable gas chromatography-ion mobility spectrometer (GC-IMS) device was used to detect the presence of volatile amine compounds in the headspace of decomposing fish. The Food and Drug Administration (FDA) largely relies on olfactory discrimination with respect to fresh and spoiled, frozen and unfrozen fish. The fish are delivered at ship docks on pallets, and each pallet of fish can range from 30-40 thousand dollars in value. Fresh fish were placed in a teflon bag and the direct headspace was interrogated. In the first three days, only low molecular weight volatile amines were detected. On the fourth day, a number of spectral signatures were observed which indicated the presence of 1,5-diaminopentane, cadaverine. Analyses typically took from 0.5-1 minute
