Examining the Mental Health Presentations of Treatment-Seeking Transgender and Gender Nonconforming (TGNC) Youth

Recent research suggests that transgender and/or gender nonconforming (TGNC) youth present with heightened levels of mental health problems compared to peers. This study seeks to examine the mental health needs of a large sample of treatment-seeking TGNC youth by comparing them to cisgender males and females. Participants were 94,804 children and youth ages 4–18 years (M = 12.1, SD = 3.72) who completed the interRAI Child and Youth Mental Health Instrument (ChYMH) or Screener (ChYMH-S) at participating mental health agencies in the Ontario, Canada. Overall, the mental health presentations of TGNC youth were similar to cisgender females but at higher acuity levels. TGNC youth showed significantly higher levels of anxiety, depression, social disengagement, positive symptoms, risk of suicide/self-harm, and were more likely to report experiencing emotional abuse, past suicide attempts, and a less strong, supportive family relationship than cisgender females and males. Clinical implications of these findings are discussed

Fast-slow asymptotic for semi-analytical ignition criteria in FitzHugh-Nagumo system

We study the problem of initiation of excitation waves in the FitzHugh-Nagumo model. Our approach follows earlier works and is based on the idea of approximating the boundary between basins of attraction of propagating waves and of the resting state as the stable manifold of a critical solution. Here, we obtain analytical expressions for the essential ingredients of the theory by singular perturbation using two small parameters, the separation of time scales of the activator and inhibitor, and the threshold in the activator's kinetics. This results in a closed analytical expression for the strength-duration curve.Comment: 10 pages, 5 figures, as accepted to Chaos on 2017/06/2

A note on leapfrogging vortex rings

In this paper we provide examples, by numerical simulation using the Navier-Stokes equations for axisymmetric laminar flow, of the 'leapfrogging' motion of two, initially identical, vortex rings which share a common axis of symmetry. We show that the number of clear passes that each ring makes through the other increases with Reynolds number, and that as long as the configuration remains stable the two rings ultimately merge to form a single vortex ring

Developing a scalable training model in global mental health: pilot study of a video-assisted training Program for Generalist Clinicians in Rural Nepal.

BackgroundIn low- and middle-income countries, mental health training often includes sending few generalist clinicians to specialist-led programs for several weeks. Our objective is to develop and test a video-assisted training model addressing the shortcomings of traditional programs that affect scalability: failing to train all clinicians, disrupting clinical services, and depending on specialists.MethodsWe implemented the program -video lectures and on-site skills training- for all clinicians at a rural Nepali hospital. We used Wilcoxon signed-rank tests to evaluate pre- and post-test change in knowledge (diagnostic criteria, differential diagnosis, and appropriate treatment). We used a series of 'Yes' or 'No' questions to assess attitudes about mental illness, and utilized exact McNemar's test to analyze the proportions of participants who held a specific belief before and after the training. We assessed acceptability and feasibility through key informant interviews and structured feedback.ResultsFor each topic except depression, there was a statistically significant increase (Δ) in median scores on knowledge questionnaires: Acute Stress Reaction (Δ = 20, p = 0.03), Depression (Δ = 11, p = 0.12), Grief (Δ = 40, p < 0.01), Psychosis (Δ = 22, p = 0.01), and post-traumatic stress disorder (Δ = 20, p = 0.01). The training received high ratings; key informants shared examples and views about the training's positive impact and complementary nature of the program's components.ConclusionVideo lectures and on-site skills training can address the limitations of a conventional training model while being acceptable, feasible, and impactful toward improving knowledge and attitudes of the participants

Adjustable Prone Trolley Design for People Suffering from Spinal Cord Injuries in Nepal

For people suffering from spinal cord injuries, it is important to stay active. However, with spinal cord injuries, the use of a wheelchair isn’t feasible. These patients require a prone trolley. A prone trolley is a horizontal pad with four wheels that a patient can maneuver and control while lying in a prone position. Our partner, International Nepal Fellowship (INF), deals directly with patients who suffer from spinal cord injuries on a daily basis. INF, a Christian, medical organization, manages a hospital in Pokhara, Nepal which specializes in treating patients with spinal cord injuries. The Nepal Prone Trolley Team’s goal is to provide our partner with a sustainable prone trolley design and create the required manufacturing documentation to enable them to produce the prone trolleys in country at their Green Pastures hospital. The team began our work by researching what a prone trolley is, how it functions and what is currently available. During the research, the team discovered that there weren’t many examples of a manually powered prone trolley or critical dimensions for ergonomics for manually powered trolleys. This drove the team to develop testing methods and preliminary designs specifically for INF. Various basic designs were considered, but, through communication with INF, a single design was chosen. Computer modeling of this design was used to decrease the overall weight of the trolley and simplify the frame. With most of the design finalized, the team is ready to begin prototyping next semester.https://mosaic.messiah.edu/engr2021/1012/thumbnail.jp

Stm1p alters the ribosome association of eukaryotic elongation factor 3 and affects translation elongation

Stm1p is a Saccharomyces cerevisiae protein that is primarily associated with cytosolic 80S ribosomes and polysomes. Several lines of evidence suggest that Stm1p plays a role in translation under nutrient stress conditions, although its mechanism of action is not yet known. In this study, we show that yeast lacking Stm1p (stm1Δ) are hypersensitive to the translation inhibitor anisomycin, which affects the peptidyl transferase reaction in translation elongation, but show little hypersensitivity to other translation inhibitors such as paromomycin and hygromycin B, which affect translation fidelity. Ribosomes isolated from stm1Δ yeast have intrinsically elevated levels of eukaryotic elongation factor 3 (eEF3) associated with them. Overexpression of eEF3 in cells lacking Stm1p results in a growth defect phenotype and increased anisomycin sensitivity. In addition, ribosomes with increased levels of Stm1p exhibit decreased association with eEF3. Taken together, our data indicate that Stm1p plays a complementary role to eEF3 in translation

Adjustable Prone Trolley Design for People Suffering from Spinal Cords Injuries in Nepal

For people who suffer from spinal cord injuries in Nepal, rehabilitation and care are often difficult to receive, especially for those for whom fewer resources are available. Thankfully, International Nepal Fellowship (INF), a non-profit serving Nepal for nearly 70 years, aids patients with spinal cord injuries at Green Pastures Hospital and Rehabilitation Centre in Pokhara, Nepal. A crucial part of any rehabilitation is adequate exercise to improve circulation and prevent sores and muscular atrophy. Yet, due to the nature of the injury, using a traditional wheelchair is not an option to fulfill this need for those with spinal cord injuries. Therefore, Green Pastures uses prone trolleys so that these patients can exercise. A prone trolley is a horizontal cushioned board where the patient lies flat on their stomach and is able to move themselves using the wheels attached to the cushioned board. Despite the importance of the prone trolley, the trolleys at Green Pastures Hospital have a few critical issues. The major issue is that the prone trolleys are internationally imported, which not only means that delivery can take months, but also that the trolleys are also difficult to repair when damaged. Both these factors severely hamper Green Pastures Hospital’s ability to provide spinal cord injured patients with the care they need. The Nepal Prone Trolley team, a part of Messiah University Collaboratory, seeks to develop and design a fundamentally better prone trolley for INF. The goal of our project is to design a prone trolley that can be fabricated by the INF staff with locally sourced materials. The advantage of this new design is that it will be easier to obtain and can easily be repaired when needed. After creating a design that satisfies our goal and fulfills the criteria of a functional prone trolley as defined by INF, we were able to fabricate a prototype of the prone trolley using resources and techniques available in Pokhara. Moving forward, we will conduct testing and redesign the trolley so that our finalized prone trolley design will be able to transform how Green Pastures Hospital aids their spinal cord injury patients.
