The Inked Experience: Professionalism and Body Modifications in Libraries

The decision to undergo body modifications can be done for a myriad of personal reasons, ranging from a love of the art, an expression of the person\u27s individuality, the display of an affiliation, or for religious and/or spiritual beliefs. In the winter of 2020, our research team set out on a quest to discover the culture of acceptance of body modifications, including tattoos, piercings, and unnatural hair colors, among those who work in and use libraries in the United States of America. With over 850 participants, the study discussed not only perceptions of professionalism, but also the number of those who have body modifications and those who wish to acquire some in the future. The study also delved into possible reasons a tattoo, piercing, or dyed hair may or may not be appropriate. For instance, participants noted a disapproval of tattoo content that includes vulgar or offensive imagery. The study also explores questions regarding placements of body modifications and surprising exceptions to the overall opinion base

Long‐term cardiovascular effects of vandetanib and pazopanib in normotensive rats

Vandetanib and pazopanib are clinically available, multi‐targeted inhibitors of vascular endothelial growth factor (VEGF) and platelet‐derived growth factor (PDGF) receptor tyrosine kinases. Short‐term VEGF receptor inhibition is associated with hypertension in 15%‐60% of patients, which may limit the use of these anticancer therapies over the longer term. To evaluate the longer‐term cardiovascular implications of treatment, we investigated the “on”‐treatment (21 days) and “off”‐treatment (10 days) effects following daily administration of vandetanib, pazopanib, or vehicle, in conscious rats. Cardiovascular variables were monitored in unrestrained Sprague‐Dawley rats instrumented with radiotelemetric devices. In Study 1, rats were randomly assigned to receive either daily intraperitoneal injections of vehicle (volume 0.5 mL; n = 5) or vandetanib 25 mg/kg/day (volume 0.5 mL; n = 6). In Study 2, rats received either vehicle (volume 0.5 mL; n = 4) or pazopanib 30 mg/kg/day (volume 0.5 mL; n = 7), dosed once every 24 hours for 21 days. All solutions were in 2% Tween, 5% propylene glycol in 0.9% saline solution. Vandetanib caused sustained increases in mean arterial pressure (MAP), systolic blood pressure (SBP), and diastolic blood pressure (DBP) compared to baseline and vehicle. Vandetanib also significantly altered the circadian cycling of MAP, SBP, and DBP. Elevations in SBP were detectable 162 hours after the last dose of vandetanib. Pazopanib also caused increases in MAP, SBP, and DBP. However, compared to vandetanib, these increases were of slower onset and a smaller magnitude. These data suggest that the cardiovascular consequences of vandetanib and pazopanib treatment are sustained, even after prolonged cessation of drug treatment

FGFR2 amplification in colorectal adenocarcinoma

FGFR2 is recurrently amplified in 5% of gastric cancers and 1%–4% of breast cancers; however, this molecular alteration has never been reported in a primary colorectal cancer specimen. Preclinical studies indicate that several FGFR tyrosine-kinase inhibitors (TKIs), such as AZD4547, have in vitro activity against the FGFR2-amplified colorectal cell line, NCI-H716. The efficacy of these inhibitors is currently under investigation in clinical trials for breast and gastric cancer. Thus, better characterizing colorectal tumors for FGFR2 amplification could identify a subset of patients who may benefit from FGFR TKI therapies. Here, we describe a novel FGFR2 amplification identified by clinical next-generation sequencing in a primary colorectal cancer. Further characterization of the tumor by immunohistochemistry showed neuroendocrine differentiation, similar to the reported properties of the NCI-H716 cell line. These findings demonstrate that the spectrum of potentially clinically actionable mutations detected by targeted clinical sequencing panels is not limited to only single-nucleotide polymorphisms and insertions/deletions but also to copy-number alterations.</jats:p

Students’ Perspective of Self-Guided Simulation Training on Process in the Initial Phase of Private Pilot Flight Training: A Preliminary Review

As the demand for flight training increases, self-guided training methods for students can be explored to determine their effect on environment for learning. A series of self-guided simulation training scenarios, aimed at assisting initial private pilot students, were created to be used on Advanced Aviation Training Devices (AATD). A pilot study was conducted where participants, using an AATD, followed a lesson plan with detailed instructions and then were evaluated by an instructor. In addition to evaluation scores, participants were given surveys on their perceptions of the experience overall and how prepared they felt for each evaluation. This preliminary study was conducted to determine student perception of self-guided training, the effectiveness of this type of training, and if there is any impact on the number of flight hours required prior to passing their private pilot pre-solo stage check

Mathematical Modeling of the Effectiveness of Facemasks in Reducing the Spread of Novel Influenza A (H1N1)

On June 11, 2009, the World Health Organization declared the outbreak of novel influenza A (H1N1) a pandemic. With limited supplies of antivirals and vaccines, countries and individuals are looking at other ways to reduce the spread of pandemic (H1N1) 2009, particularly options that are cost effective and relatively easy to implement. Recent experiences with the 2003 SARS and 2009 H1N1 epidemics have shown that people are willing to wear facemasks to protect themselves against infection; however, little research has been done to quantify the impact of using facemasks in reducing the spread of disease. We construct and analyze a mathematical model for a population in which some people wear facemasks during the pandemic and quantify impact of these masks on the spread of influenza. To estimate the parameter values used for the effectiveness of facemasks, we used available data from studies on N95 respirators and surgical facemasks. The results show that if N95 respirators are only 20% effective in reducing susceptibility and infectivity, only 10% of the population would have to wear them to reduce the number of influenza A (H1N1) cases by 20%. We can conclude from our model that, if worn properly, facemasks are an effective intervention strategy in reducing the spread of pandemic (H1N1) 2009

Assessment of an established dialysis nurse practitioner model of care using mixed methods research

Aims and Objectives: To assess a dialysis nurse practitioner ( NP ) model of care by examining satisfaction, quality of life ( QOL ) and clinical outcomes of haemodialysis patients and explore experiences of dialysis nurses. Design: Mixed methods. Methods: Database analyses of dialysis indices amongst a sample ( n = 45 ) of haemodialysis patients; a survey ( n = 27 ) examining patient experience, satisfaction and QOL; and in-depth interviews with a sample ( n = 10 ) of nurses. Results: Nurses commended the NP role, with five themes emerging: “managing and co-ordinating”, “streamlining and alleviating”, “developing capability”, “supporting innovation and quality” and “connecting rurally”. Patients’ average age was 66 years and 71% were male. Patients’ satisfaction with the care they received was rated 3.5/4 or higher across seven parameters and the average QOL score was 7.9/10. Conclusion: The NP model of care is effective in enhancing patient care within a collaborative framework. The challenge is to sustain, and enhance the model, through mentorship programs for potential candidates

A comparison of bioimpedance analysis vs. dual x-ray absorptiometry for body composition assessment in postpartum women and non-postpartum controls

Postpartum fat mass (FM) and fat-free mass (FFM) may be informative predictors of future disease risk among women; hence, there is growing use of bioelectrical impedance analysis (BIA) to quantify FFM and FM among postpartum women due to the quick, non-invasive, and inexpensive nature of BIA. Despite this, very few studies have examined BIA\u27s performance, and it remains unclear as to whether specific BIA equations are needed for postpartum women. To explore these questions, we measured total body FFM and FM with a multi-frequency, segmental BIA, and dual-X-ray absorptiometry (DXA) in (1) women at one and four months postpartum

Behavioral Health Integration in Primary Care

Behavioral Health Integration in Primary Care Casey Zapata, Depts. of Psychology and English, Demetrius Carter, & MaryKate Crawford, and Samantha Mladen, Emily Donovan, Amber Fox, & Kristen O’Loughlin, Dept. of Psychology Graduate Students, with Dr. Bruce Rybarczyk, Dept. of Psychology Background/Aims: Due to limited access to mental health care, many patients present to primary care with mental health concerns, such as depression and anxiety. Integrated primary care (IPC), an emerging practice model that integrates behavioral health providers with medical providers in primary care, has been demonstrated to improve patient outcomes. This project aims to characterize patients being seen in safety-net IPC, both demographically and clinically. Methods: The data were collected across three safety-net clinics in the Richmond area. The sample consisted of 96 adult patients: 68 female (71%), 24 male (25%), 1 non binary (1%), and 3 not collected (3%); 54 African-American (56%), 29 White (30%), 1 Asian (1%), 1 Other (1%), and 11 not collected (12%). Measures included a patient-completed checklist of patients’ behavioral health concerns, the PHQ-9 for depression, the GAD-7 for anxiety, and clinician-completed chart review for demographic factors. Results: Of the 72 patients who completed the GAD-7, patients reported 13 (18%) severe symptoms of anxiety, 11 (15%) moderate symptoms, 15 (21%) mild symptoms, and 33 (46%) subclinical symptoms. For the 37 patients who completed the PHQ-9, patients reported 7 (19%) severe depressive symptoms, 10 (27%) moderately severe symptoms, 12 (32%) moderate symptoms, 6 (16%) mild symptoms, and 2 (5%) subclinical symptoms. The six most commonly patient-reported problems were stress (n= 73), anxiety (n= 70), depression (n= 65), sleep (n = 55), grief (n = 53), and irritability (n= 53). When asked to rank their top three concerning problems, the five concerns most commonly ranked as top problems were: : (1) anxiety (n = 29), (2) stress (n = 28), (3) depression (n = 27), (4) sleep (n=16), and (5) weight (n=15). Further, 56 (58%) participants reported both depression and anxiety as among their top three concerns. Discussion: Anxiety and depression were reported by the majority of patients, with 33% experiencing at least moderate anxiety and 78% experiencing at least moderate depression. Additionally, anxiety and depression were cited as the third most commonly reported concerns, respectively, as well as ranked within the top three most concerning problems for most participants. Stress, anxiety, depression, and sleep were included in both the most commonly reported problems and the most common top three concerns of participants, suggesting that these concerns are both pervasive and troublesome for participants. Over time, this project will prioritize increasing sample size and tracking longitudinal trends. The continued study of safety-net IPC may allow for increasing access to behavioral health, identifying common behavioral health concerns in primary care, and meeting unmet patient needs.https://scholarscompass.vcu.edu/uresposters/1340/thumbnail.jp

Artificial escape from XCI by DNA methylation editing of the CDKL5 gene.

A significant number of X-linked genes escape from X chromosome inactivation and are associated with a distinct epigenetic signature. One epigenetic modification that strongly correlates with X-escape is reduced DNA methylation in promoter regions. Here, we created an artificial escape by editing DNA methylation on the promoter of CDKL5, a gene causative for an infantile epilepsy, from the silenced X-chromosomal allele in human neuronal-like cells. We identify that a fusion of the catalytic domain of TET1 to dCas9 targeted to the CDKL5 promoter using three guide RNAs causes significant reactivation of the inactive allele in combination with removal of methyl groups from CpG dinucleotides. Strikingly, we demonstrate that co-expression of TET1 and a VP64 transactivator have a synergistic effect on the reactivation of the inactive allele to levels &gt;60% of the active allele. We further used a multi-omics assessment to determine potential off-targets on the transcriptome and methylome. We find that synergistic delivery of dCas9 effectors is highly selective for the target site. Our findings further elucidate a causal role for reduced DNA methylation associated with escape from X chromosome inactivation. Understanding the epigenetics associated with escape from X chromosome inactivation has potential for those suffering from X-linked disorders

Federal and state cooperation necessary but not sufficient for effective regional mental health systems : insights from systems modelling and simulation

For more than a decade, suicide rates in Australia have shown no improvement despite significant investment in reforms to support regionally driven initiatives. Further recommended reforms by the Productivity Commission call for Federal and State and Territory Government funding for mental health to be pooled and new Regional Commissioning Authorities established to take responsibility for efficient and effective allocation of ‘taxpayer money.’ This study explores the sufficiency of this recommendation in preventing ongoing policy resistance. A system dynamics model of pathways between psychological distress, the mental health care system, suicidal behaviour and their drivers was developed, tested, and validated for a large, geographically diverse region of New South Wales; the Hunter New England and Central Coast Primary Health Network (PHN). Multi-objective optimisation was used to explore potential discordance in the best-performing programs and initiatives (simulated from 2021 to 2031) across mental health outcomes between the two state-governed Local Health Districts (LHDs) and the federally governed PHN. Impacts on suicide deaths, mental health-related emergency department presentations, and service disengagement were explored. A combination of family psychoeducation, post-attempt aftercare, and safety planning, and social connectedness programs minimises the number of suicides across the PHN and in the Hunter New England LHD (13.5% reduction; 95% interval, 12.3–14.9%), and performs well in the Central Coast LHD (14.8% reduction, 13.5–16.3%), suggesting that aligned strategic decision making between the PHN and LHDs would deliver substantial impacts on suicide. Results also highlighted a marked trade-off between minimising suicide deaths versus minimising service disengagement. This is explained in part by the additional demand placed on services of intensive suicide prevention programs leading to increases in service disengagement as wait times for specialist community based mental health services and dissatisfaction with quality of care increases. Competing priorities between the PHN and LHDs (each seeking to optimise the different outcomes they are responsible for) can undermine the optimal impact of investments for suicide prevention. Systems modelling provides essential regional decision analysis infrastructure to facilitate coordinated federal and state investments for optimal impacts
