Swimmers’ Upper Trapezius Activation During Shoulder Abduction Compared to Non-Overhead Athletes

Overhead sports such as baseball, tennis, volleyball, softball and swimming are known to cause rotator cuff imbalances and injuries. These injuries are typically caused by the repeated use of “throwing motion,” where the humerus is externally rotated and shoulder abducted and elevated. Previous research has shown that the function of the upper trapezius muscle in overhead athletes is likely to have improper activation (timing, magnitude) during various shoulder motions and/or activities of daily living. Swimmers are especially susceptible to this improper activation due to the use of their upper limbs in a repeated throwing motion. The added resistance of the water during the catch of the stroke intensifies the risk of muscular dysfunction. Unfortunately, research is limited surrounding muscular activation in these athletes and it is unclear how the rigor of swimming affects long-term muscular function. Understanding the muscular function in swimmers will aid not only athletes in better understanding their body, but also coaches and athletic trainers in creating the most effective training programs and injury prevention protocols. Therefore, the purpose of this study is to assess swimming’s effect on the upper trapezius activation of these athletes. Shoulder abduction, or shoulder “fly,” exercises were performed at a pre-selected and self-selected weight. Surface electromyography sensors were attached to the participant’s upper trapezius, bilaterally, in order to measure muscular activation levels. Additionally, motion capture technology was utilized to quantify shoulder and arm position. The results of this study will add to the limited body of knowledge surrounding the competitive swimming and, hopefully, assist exercise professionals and athletes alike in understanding swimming’s effects on muscular activation

Naming the Spiritual: The Hidden Dimension of Social Work Practice

The history of spirituality and the social work profession is marked by ambivalence, even avoidance. This paper expands the definition of social work practice to include a spiritual dimension. The authors suggest that this dimension is not new, but its importance has not been sufficiently articulated. The spiritual dimension of practice includes consciousness of and attention to the client\u27s search for meaning. Both the helping relationship and many of the issues that clients bring are spiritual in nature. A simple framework to help practitioners identify spiritual issues is presented and illustrated by a case example

Cyber Space Odyssey: A Competitive, Team-Oriented Serious Game in Computer Networking

Cyber Space Odyssey (CSO) is a novel serious game supporting computer networking education by engaging students in a race to successfully perform various cybersecurity tasks in order to collect clues and solve a puzzle in virtual near-Earth 3D space. Each team interacts with the game server through a dedicated client presenting a multimodal interface, using a game controller for navigation and various desktop computer networking tools of the trade for cybersecurity tasks on the game\u27s physical network. Specifically, teams connect to wireless access points, use packet monitors to intercept network traffic, decrypt and reverse engineer that traffic, craft well-formed and meaningful responses, and transmit those responses. Successful completion of these physical network actions to solve a sequence of increasingly complex problems is necessary to progress through the virtual, story-driven adventure. Use of the networking tools reinforces networking theory and offers hands-on practical training requisite for today\u27s cyberoperators. This paper presents the learning outcomes targeted by a classroom intervention based on CSO, the design and implementation of the game, a pedagogical overview of the overall intervention, and four years of quantitative and qualitative data assessing its effectiveness

2013-2014 Clemson LGBTQ Task Force Recommendations

In December of 2011, a group of faculty, staff, students, alumni, and other Clemson community members came together to discuss the invisibility of the queer and trans communities in the “Clemson family” message. The event was held at the Madren Center and sponsored in part by the then‐Dean of Students Joy Smith. One of the motivating factors of the meeting was Clemson University’s unfortunately low score, 2 out of 5 stars, on the National LGBT‐Friendly Campus Climate Assessment tool from Campus Pride. The average score among the Top‐20 Public Schools (U.S. News & World Report, 2013) is 4.4 out of 5 stars. Of the Top‐25 Public Schools, only Clemson scored below a 3 out of 5 stars. Our main motivation stemmed from the controversial off‐campus beating of a gay Clemson student. Leading up to the confrontation gay slurs were used against two students and one student suffered a physical attack. From the meeting’s exhaustive list of findings, three items were identified as priorities: establishment of a LGBTQ commission, establishment of a LGBTQ resource center, and same‐sex spousal benefits. Of the three, the establishment of a commission was pursued by Leon Wiles (Chief Diversity Officer), Susan Hilligoss (English faculty), and Joshua Morgan (library staff). Bylaws were drafted, and in November of 2012, a smaller representative group appeared before President Jim Barker to present their rationale for the establishment of a commission. The president responded by appointing a task force to act in an advisory capacity and to continue the discussion about how to make members of the queer and trans communities feel welcome and safe in the Clemson family

Acceptability of nurse-led reviews for inflammatory rheumatological conditions: A qualitative study.

Background People with inflammatory rheumatological conditions (IRCs), are at increased risk of comorbidities such as cardiovascular disease, osteoporosis, anxiety and depression. The INCLUDE pilot trial evaluated a nurse-delivered review of people with IRCs which sought to identify and initiate management of comorbid conditions. Aim A nested qualitative study was undertaken to examine the acceptability of the INCLUDE review. Methods A qualitative interview-based design in UK primary care settings. A purposive sample of 20 patients who attended an INCLUDE review, were interviewed. Inductive thematic analysis was undertaken. Themes were agreed through multidisciplinary team discussion and mapped onto constructs of the Theoretical Framework of Acceptability (TFA). Results Six themes mapped onto six of the seven TFA constructs. Patients reported the review to be effective by identifying and initiating management of previously unrecognised comorbid conditions. Some participants reported barriers to following recommendations, such as lifestyle modifications or taking more medication. Conclusion A nurse-delivered review to identify comorbidities is acceptable to patients with IRCs. The TFA provided a novel analytical lens

Phylogenetic Relationships of Monocots Based on the Highly Informative Plastid Gene ndhF

We used ndhF sequence variation to reconstruct relationships across 282 taxa representing 78 monocot families and all 12 orders. The resulting tree is highly resolved and places commelinids sister to Asparagales, with both sister to Liliales—Pandanales in the strict consensus; Pandanales are sister to Dioscoreales in the bootstrap majority-rule tree, just above Petrosaviales. Acorales are sister to all other monocots, with Alismatales sister to all but Acorales. Relationships among the four major clades of commelinids remain unresolved. Relationships within orders are consistent with those based on rbcL, alone or in combination with atpB and 18S nrDNA, and generally better supported: ndhF contributes more than twice as many informative characters as rbcL, and nearly as many as rbcL, atpB, and 18S nrDNA combined. Based on functional arguments, we hypothesized that net venation and fleshy fruits should both evolve—and thus undergo concerted convergence—in shaded habitats, and revert to parallel venation and dry, passively dispersed fruits in open, sunny habitats. Our data show that net venation arose at least 26 times and disappeared 9 times, whereas fleshy fruits arose 22 times and disappeared 11 times. Both traits arose together at least 15 times and disappeared together 5 times. They thus show a highly significant pattern of concerted convergence (P \u3c 10-9) and are each even more strongly associated with shaded habitats (P \u3c 10-10 to 10-23); net venation is also associated, as predicted, with broad-leaved aquatic plants. Exceptions to this pattern illustrate the importance of other selective constraints and phylogenetic inertia

Combining fish and benthic communities into multiple regimes reveals complex reef dynamics

Abstract Coral reefs worldwide face an uncertain future with many reefs reported to transition from being dominated by corals to macroalgae. However, given the complexity and diversity of the ecosystem, research on how regimes vary spatially and temporally is needed. Reef regimes are most often characterised by their benthic components; however, complex dynamics are associated with losses and gains in both fish and benthic assemblages. To capture this complexity, we synthesised 3,345 surveys from Hawai‘i to define reef regimes in terms of both fish and benthic assemblages. Model-based clustering revealed five distinct regimes that varied ecologically, and were spatially heterogeneous by island, depth and exposure. We identified a regime characteristic of a degraded state with low coral cover and fish biomass, one that had low coral but high fish biomass, as well as three other regimes that varied significantly in their ecology but were previously considered a single coral dominated regime. Analyses of time series data reflected complex system dynamics, with multiple transitions among regimes that were a function of both local and global stressors. Coupling fish and benthic communities into reef regimes to capture complex dynamics holds promise for monitoring reef change and guiding ecosystem-based management of coral reefs

Efficacy of host cell serine protease inhibitor MM3122 against SARS-CoV-2 for treatment and prevention of COVID-19

We developed a novel class of peptidomimetic inhibitors targeting several host cell human serine proteases, including transmembrane protease serine 2 (TMPRSS2), matriptase, and hepsin. TMPRSS2 is a membrane-associated protease that is highly expressed in the upper and lower respiratory tracts and is utilized by SARS-CoV-2 and other viruses to proteolytically process their glycoproteins, enabling host cell entry, replication, and dissemination of new virus particles. We have previously shown that compound MM3122 exhibited subnanomolar potency against all three proteases and displayed potent antiviral effects against SARS-CoV-2 in a cell viability assay. Herein, we demonstrate that MM3122 potently inhibits viral replication in human lung epithelial cells and is also effective against the EG.5.1 variant of SARS-CoV-2. Furthermore, we evaluated MM3122 in a mouse model of COVID-19 and demonstrated that MM3122 administered intraperitoneally (IP) before (prophylactic) or after (therapeutic) SARS-CoV-2 infection had significant protective effects against weight loss and lung congestion and reduced pathology. Amelioration of COVID-19 disease was associated with a reduction in proinflammatory cytokine and chemokine production after SARS-CoV-2 infection. Prophylactic, but not therapeutic, administration of MM3122 also reduced virus titers in the lungs of SARS-CoV-2-infected mice. Therefore, MM3122 is a promising lead candidate small-molecule drug for the treatment and prevention of infections caused by SARS-CoV-2 and other coronaviruses

A pilot study of a nurse-led integrated care review (the INCLUDE review) for people with inflammatory rheumatological conditions in primary care: feasibility study findings.

BACKGROUND: People with inflammatory rheumatological conditions such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, polymyalgia rheumatica and giant cell arteritis are at an increased risk of common comorbidities including cardiovascular disease, osteoporosis and mood problems, leading to increased morbidity and mortality. Identifying and treating these problems could lead to improved patient quality of life and outcomes. Despite these risks being well-established, patients currently are not systematically targeted for management interventions for these morbidities. This study aimed to assess the feasibility of conducting a randomised controlled trial (RCT) of a nurse-led integrated care review in primary care to identify and manage these morbidities. METHODS: A pilot cluster RCT was delivered across four UK general practices. Patients with a diagnostic Read code for one of the inflammatory rheumatological conditions of interest were recruited by post. In intervention practices (n = 2), eligible patients were invited to attend the INCLUDE review. Outcome measures included health-related quality of life (EQ-5D-5L), patient activation, self-efficacy and treatment burden. A sample (n = 24) of INCLUDE review consultations were audio-recorded and assessed against a fidelity checklist. RESULTS: 453/789 (57%) patients responded to the invitation, although 114/453 (25%) were excluded as they either did not fulfil eligibility criteria or failed to provide full written consent. In the intervention practices, uptake of the INCLUDE review was high at 72%. Retention at 3 and 6?months both reached pre-specified success criteria. Participants in intervention practices had more primary care contacts than controls (mean 29 vs 22) over the 12?months, with higher prescribing of all relevant medication classes in participants in intervention practices, particularly so for osteoporosis medication (baseline 29% vs 12?month 46%). The intervention was delivered with fidelity, although potential areas for improvement were identified. CONCLUSIONS: The findings of this pilot study suggest it is feasible to deliver an RCT of the nurse-led integrated care (INCLUDE) review in primary care. A significant morbidity burden was identified. Early results suggest the INCLUDE review was associated with changes in practice. Lessons have been learnt around Read codes for patient identification and refining the nurse training. TRIAL REGISTRATION: ISRCTN, ISRCTN12765345

Swine acute diarrhea syndrome coronavirus replication in primary human cells reveals potential susceptibility to infection

Zoonotic coronaviruses represent an ongoing threat, yet the myriads of circulating animal viruses complicate the identification of higher-risk isolates that threaten human health. Swine acute diarrhea syndrome coronavirus (SADS-CoV) is a newly discovered, highly pathogenic virus that likely evolved from closely related HKU2 bat coronaviruses, circulating in Rhinolophus spp. bats in China and elsewhere. As coronaviruses cause severe economic losses in the pork industry and swine are key intermediate hosts of human disease outbreaks, we synthetically resurrected a recombinant virus (rSADS-CoV) as well as a derivative encoding tomato red fluorescent protein (tRFP) in place of ORF3. rSADS-CoV replicated efficiently in a variety of continuous animal and primate cell lines, including human liver and rectal carcinoma cell lines. Of concern, rSADS-CoV also replicated efficiently in several different primary human lung cell types, as well as primary human intestinal cells. rSADS-CoV did not use human coronavirus ACE-2, DPP4, or CD13 receptors for docking and entry. Contemporary human donor sera neutralized the group I human coronavirus NL63, but not rSADS-CoV, suggesting limited human group I coronavirus cross protective herd immunity. Importantly, remdesivir, a broad-spectrum nucleoside analog that is effective against other group 1 and 2 coronaviruses, efficiently blocked rSADS-CoV replication in vitro. rSADS-CoV demonstrated little, if any, replicative capacity in either immune-competent or immunodeficient mice, indicating a critical need for improved animal models. Efficient growth in primary human lung and intestinal cells implicate SADS-CoV as a potential higher-risk emerging coronavirus pathogen that could negatively impact the global economy and human health
