The interprofessional practice experiences of final-semester prelicensure BSN students completing clinical immersion: A descriptive qualitative study.

BACKGROUND: The goal of interprofessional practice experiences in health professions programs is to develop interprofessional collaborative practice skills. PURPOSE: The purpose of the study was to explore the meaning final-semester Bachelor of Science in Nursing students attributed to interprofessional practice experiences during clinical immersion. METHODS: The theoretical framework for this descriptive qualitative study was experiential learning theory. A sample of 12 participants was drawn from final-semester prelicensure Bachelor of Science in Nursing students at a college of nursing at a public research university. Data were collected through one-on-one semi-structured interviews and analyzed through inductive thematic analysis. RESULTS: The analysis yielded four themes: professional and interprofessional identity, working with team members, communication practices, and trusting relationships. Patterns across themes were clinical environment culture, nursing school preparation, nurse preceptor role, fear/concern/worry, and night shift. CONCLUSION: Consistency in preceptors, welcoming clinical environments, and opportunities to practice communicating with team members contributed to interprofessional collaborative practice skill development and improved perceptions of readiness for practice. Academic and clinical educators may use findings to (a) identify immersion placements for interprofessional practice experiences, (b) design curricula reflective of interprofessional practice, (c) advance teaching strategies to promote interprofessional practice, and (d) create learning environments that aid in professional and interprofessional identity formation.

Quantifying and Qualifying Nursing Professional Development Practitioner Workload.

Nursing professional development practitioners are integral leaders who continue to seek tangible ways to show their value. A tool was designed to capture workload based upon the scope and standards of nursing professional development practice and successfully captured the workload of over 200 practitioners. The measures used in this project can serve as a guide for others to describe nursing professional development practitioner workload.

Determining the impact of vaccination on SARS-CoV-2 RT-PCR cycle threshold values and infectious viral titres.

Background: As the COVID-19 pandemic continues, efforts to better understand severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral shedding and transmission in both unvaccinated and vaccinated populations remain critical to informing public health policies and vaccine development. The utility of using real time RT-PCR cycle threshold values (CT values) as a proxy for infectious viral litres from individuals infected with SARS-CoV-2 is yet to be fully understood. This retrospective observational cohort study compares quantitative infectious viral litres derived from a focus-forming viral titre assay with SARS-CoV-2 RT-PCR CT values in both unvaccinated and vaccinated individuals infected with the Delta strain. Methods: Nasopharyngeal swabs positive for SARS-CoV-2 by RT-PCR with a CT value <27 collected from 26 June to 17 October 2021 at the University of Vermont Medical Center Clinical Laboratory for which vaccination records were available were included. Partially vaccinated and individuals <18 years of age were excluded. Infectious viral litres were determined using a micro-focus forming assay under BSL-3 containment. Results: In total, 119 specimens from 22 unvaccinated and 97 vaccinated individuals met all inclusion criteria and had sufficient residual volume to undergo viral titring. A negative correlation between RT-PCR CT values and viral litres was observed in both unvaccinated and vaccinated groups. No difference in mean CT value or viral titre was detected between vaccinated and unvaccinated groups. Viral litres did not change as a function of time since vaccination. Conclusions: Our results add to the growing body of knowledge regarding the correlation of SARS-CoV-2 RNA levels and levels of infectious virus. At similar CT values, vaccination does not appear to impact an individual's potential infectivity when infected with the Delta variant.

Successful treatment of rhino-cerebral mucormycosis with dual antifungal therapy and minimal surgical debridement.

The authors report the case of a 42-year-old female with history of type I diabetes mellitus and recent episode of diabetic ketoacidosis who presented with symptoms of epistaxis, gastrointestinal upset, hyperglycemia, confusion, and a cough. She was found to have rhino-cerebral mucormycosis with associated multi-focal strokes and a left internal carotid artery pseudoaneurysm. Her infection was successfully treated with dual-antifungal therapy consisting of liposomal amphotericin B and isavuconazole, and required only minimal surgical debridement.

The Impact of Standardized Infectious Diseases Consultation on Postsplenectomy Care and Outcomes.

Background: Patients who receive splenectomy are at risk for overwhelming postsplenectomy infection (OPSI). Guidelines recommend that adult asplenic patients receive a complement of vaccinations, education on the risks of OPSI, and on-demand antibiotics. However, prior literature suggests that a majority of patients who have had a splenectomy receive incomplete asplenic patient care and thus remain at increased risk. This study assessed the impact of standardized involvement of infectious diseases (ID) providers on asplenic patient care outcomes in patients undergoing splenectomy. Methods: A quasi-experimental study design compared a prospective cohort of patients undergoing splenectomy from August 2017 to June 2021 who received standardized ID involvement in care of the asplenic patient with a historic control cohort of patients undergoing splenectomy at the same institution from January 2010 through July 2017 who did not. There were 11 components of asplenic patient care defined as primary outcomes. Secondary outcomes included the occurrence of OPSI, death, and death from OPSI. Results: Fifty patients were included in the prospective intervention cohort and 128 in the historic control cohort. There were significant improvements in 9 of the 11 primary outcomes in the intervention arm as compared with the historic controls. Survival analysis showed no statistically significant difference in the incidence of OPSI-free survival between the groups (P = .056), though there was a trend toward improvement in the prospective intervention arm. Conclusions: Standardized involvement of an ID provider in the care of patients undergoing splenectomy improves asplenic patient care outcomes. Routine involvement of ID in this setting may be warranted.

Fear of Dependency and Life-Space Mobility as Predictors of Attitudes Toward Assistive Devices in Older Adults.

Assistive devices can help older adults remain independent; however, they may hesitate to use them due to fears of appearing dependent by embodying aging stereotypes. Reluctance to use assistive devices may lead to decreased life space mobility. The selective optimization with compensation (SOC) model posits that older adults employ strengths to accommodate for age-related functioning declines. The current study examines the predictive power of health perceptions, dependency fears, aging stereotypes, and life space on older adults' views of assistive devices. Results suggest that older adults with greater life space and dependency fears are more likely to view assistive devices positively.

Honors students in the health professions: An academic-practice partnership for developing interprofessional competencies through simulation.

Abundant literature supports the value of interprofessional education (IPE) in health profession programs, but few studies focus on undergraduate honors students. The goals of this academic-practice partnership quality improvement project were to increase awareness of IPE, provide experiential opportunities to learn the principles of interprofessional practice, assess perceptions of readiness for practice, and to explore motivations and learning expectations of undergraduate nursing and pre-medical honors students. Average scores on the Readiness for Interprofessional Learning Scale (RIPLS) increased in several areas after the IPE simulation experiences, with small to medium effect sizes (Cohen's d) on individual items and two subscales (Teamwork & Collaboration and Positive Professional Identity). Themes identified in the narrative data were opportunity, fun, self-awareness, situational awareness, and the value of teamwork. These findings add to literature on honor students' expectations and motivations for learning and can be used in designing interprofessional collaborative learning activities for undergraduate health profession students.

Retbindin mediates light-damage in mouse retina while its absence leads to premature retinal aging.

Vision requires the transport and recycling of the pigment 11-cis retinaldehyde (retinal) between the retinal pigment epithelium (RPE) and photoreceptors. 11-cis retinal is also required for light-mediated photoreceptor death in dark-adapted mouse eye, probably through overstimulation of rod cells adapted for low light. Retbindin is a photoreceptor-specific protein, of unclear function, that is localized between the RPE and the tips of the photoreceptors. Unexpectedly, young Rtbdn-KO mice, with targeted deletion (KO) of retbindin, showed delayed regeneration of retinal function after bleaching and were strongly resistant to light-induced photoreceptor death. Furthermore, bio-layer interferometry binding studies showed recombinant retbindin had significant affinity for retinoids, most notably 11-cis retinal. This suggests that retbindin mediates light damage, probably through a role in transport of 11-cis retinal. In Rtbdn-KO mice, retinal development was normal, as were amplitudes of rod and cone electroretinograms (ERG) up to 4 months, although implicit times and c-waves were affected. However, with aging, both light- and dark-adapted ERG amplitudes declined significantly and photoreceptor outer segments became disordered, However, in contrast to other reports, there was little retinal degeneration or drop in flavin levels. The RPE developed vacuoles and lipid, protein and calcium deposits reminiscent of age-related macular degeneration. Other signs of premature aging included loss of OPN4+ retinal ganglion cells and activation of microglia. Thus, retbindin plays an unexpected role in the mammalian visual cycle, probably as an adaptation for vision in dim light. It mediates light damage in the dark-adapted eye, but also plays a role in light-adapted responses and in long term retinal homeostasis.

Endocarditis and systemic embolization from Whipple's disease.

Whipple's disease (WD), caused by infection with the organism Tropheryma whipplei, is a rare disease that classically presents with diarrhea, weight loss, and polyarthralgia. Less commonly, Whipple's Disease can presentation with endocarditis or neurologic infections. The authors report a patient with Whipple's Disease endocarditis whose initial presentation was acute lower extremity arterial occlusion, and review current literature regarding the epidemiology, diagnosis, treatment, and prognosis of Whipple's Disease endocarditis.

Amelotin is expressed in retinal pigment epithelium and localizes to hydroxyapatite deposits in dry age-related macular degeneration.

Deposition of hydroxyapatite (HAP) basal to the retinal pigment epithelium (RPE) is linked to the progression of age-related macular degeneration (AMD). Serum-deprivation of RPE cells in culture mimics some features of AMD. We now show that serum-deprivation also leads to the induction of amelotin (AMTN), a protein involved in hydroxyapatite mineralization in enamel. HAP is formed in our culture model and is blocked by siRNA inhibition of AMTN expression. In situ hybridization and immunofluorescence imaging of human eye tissue show that AMTN is expressed in RPE of donor eyes with geographic atrophy ("dry" AMD) in regions with soft drusen containing HAP spherules or nodules. AMTN is not found in hard drusen, normal RPE, or donor eyes diagnosed with wet AMD. These findings suggest that AMTN is involved in formation of HAP spherules or nodules in AMD, and as such provides a new therapeutic target for slowing disease progression.

Cautionary study on the effects of pay for performance on quality of care: a pilot randomised controlled trial using standardised patients.

BACKGROUND: Due to the difficulty of studying incentives in practice, there is limited empirical evidence of the full-impact pay-for-performance (P4P) incentive systems. OBJECTIVE: To evaluate the impact of P4P in a controlled, simulated environment. DESIGN: We employed a simulation-based randomised controlled trial with three standardised patients to assess advanced practice providers' performance. Each patient reflected one of the following: (A) indicated for P4P screenings, (B) too young for P4P screenings, or (C) indicated for P4P screenings, but screenings are unrelated to the reason for the visit. Indication was determined by the 2016 Centers for Medicare and Medicaid Services quality measures. INTERVENTION: The P4P group was paid $150 and received a bonus of $10 for meeting each of five outcome measures (breast cancer, colorectal cancer, pneumococcal, tobacco use and depression screenings) for each of the three cases (max $300). The control group received $200. SETTING: Learning resource centre. PARTICIPANTS: 35 advanced practice primary care providers (physician assistants and nurse practitioners) and 105 standardised patient encounters. MEASUREMENTS: Adherence to incentivised outcome measures, interpersonal communication skills, standards of care, and misuse. RESULTS: The Type a patient was more likely to receive indicated P4P screenings in the P4P group (3.82 out of 5 P4P vs 2.94 control, p=0.02), however, received lower overall standards of care under P4P (31.88 P4P vs 37.06 control, p=0.027). The Type b patient was more likely to be prescribed screenings not indicated, but highlighted by P4P: breast cancer screening (47% P4P vs 0% control, p<0.01) and colorectal cancer screening (24% P4P vs 0% control, p=0.03). The P4P group over-reported completion of incentivised measures resulting in overpayment (average of $9.02 per patient). LIMITATIONS: A small sample size and limited variability in patient panel limit the generalisability of findings. CONCLUSIONS: Our findings caution the adoption of P4P by highlighting the unintended consequences of the incentive system.

Sensors and Psychomotor Metrics: A Unique Opportunity to Close the Gap on Surgical Processes and Outcomes.

The surgical process remains elusive to many. This paper presents two independent empirical investigations where psychomotor skill metrics were used to quantify elements of the surgical process in a procedural context during surgical tasks in a simulated environment. The overarching goal of both investigations was to address the following hypothesis: Basic motion metrics can be used to quantify specific aspects of the surgical process including instrument autonomy, psychomotor efficiency, procedural readiness, and clinical errors. Electromagnetic motion tracking sensors were secured to surgical trainees' (N = 64) hands for both studies, and several motion metrics were investigated as a measure of surgical skill. The first study assessed performance during a bowel repair and laparoscopic ventral hernia (LVH) repair in comparison to a suturing board task. The second study assessed performance in a VR task in comparison to placement of a subclavian central line. The findings of the first study support our subhypothesis that motion metrics have a generalizable application to surgical skill by showing significant correlations in instrument autonomy and psychomotor efficiency during the suturing task and bowel repair (idle time: r = 0.46, p < 0.05; average velocity: r = 0.57, p < 0.05) and the suturing task and LVH repair (jerk magnitude: r = 0.36, p < 0.05; bimanual dexterity: r = 0.35, p < 0.05). In the second study, performance in VR (steering and jerkiness) correlated to clinical errors (r = 0.58, p < 0.05) and insertion time (r = 0.55, p < 0.05) in placement of a subclavian central line. Both gross (dexterity) and fine motor skills (steering) were found to be important as well as efficiency (i.e., idle time, duration, velocity) when seeking to understand the quality of surgical performance. Both studies support our hypotheses that basic motion metrics can be used to quantify specific aspects of the surgical process and that the use of different technologies and metrics are important for comprehensive investigations of surgical skill.

Can Virtual Reality Be Used to Track Skills Decay During the Research Years?

BACKGROUND: Time away from surgical practice can lead to skills decay. Research residents are thought to be prone to skills decay, given their limited experience and reduced exposure to clinical activities during their research training years. This study takes a cross-sectional approach to assess differences in residents' skills at the beginning and end of their research years using virtual reality. We hypothesized that research residents will have measurable decay in psychomotor skills when evaluated using virtual reality. METHODS: Surgical residents (n = 28) were divided into two groups; the first group was just beginning their research time (clinical residents: n = 19) and the second group (research residents: n = 9) had just finished at least 2 y of research. All participants were asked to perform a target-tracking task using a haptic device, and their performance was compared using Welch's t-test. RESULTS: Research residents showed a higher level of "tracking error" (1.69 ± 0.44 cm versus 1.40 ± 0.19 cm; P = 0.04) and a similar level of "path length" (62.5 ± 10.5 cm versus 62.1 ± 5.2 cm; P = 0.92) when compared with clinical residents. CONCLUSIONS: The increased "tracking error" among residents at the end of their research time suggests fine psychomotor skills decay in residents who spend time away from clinical duties during laboratory time. This decay demonstrates the need for research residents to regularly participate in clinical activities, simulation, or assessments to minimize and monitor skills decay while away from clinical practice. Additional longitudinal studies may help better map learning and decay curves for residents who spend time away from clinical practice.

Creating Synergy between Academia and Practice: The Arizona State University and Mayo Clinic Arizona Model.

BACKGROUND: The academic-practice partnership began in 2005 with a collaborative Pre-licensure Bachelor of Science in Nursing (BSN) program. Since that time the partnership has broadened to include faculty development, evidence-based practice, interprofessional education, and research initiatives. PURPOSE: The purpose is to share the outcomes of this academic-practice partnership and to provide a model for other institutions. METHODS: This successful partnership is grounded in the American Association of Colleges of Nursing and the American Organization of Nurse Executives' eight guiding principles for academic-practice partnerships. The cornerstones to the partnership are communication, collaboration, and mutual respect. RESULTS: The initial outcomes of this collaboration increased enrollment, thereby increasing the number of BSN prepared registered nurses; created opportunities for clinical nurses to teach; increased the number of nursing faculty; and capitalized on the strengths of each partner. CONCLUSION: The most exciting aspect of this partnership is the shared commitment to decrease the gap between nursing education and practice; thus, improving the quality of nursing education, advancing the practice of nursing and healthcare delivery, and enhancing the health of our community. Consistent with the AACN-AONE recommendations, this academic-practice partnership prepares nurses of the future to be evidence-based practitioners and creates opportunities for nurses to achieve educational and career advancements.

Screening surgical residents' laparoscopic skills using virtual reality tasks: Who needs more time in the sim lab?

BACKGROUND: This study investigated the possibility of using virtual reality perceptual-motor tasks as a screening tool for laparoscopic ability. We hypothesized that perceptual-motor skills assessed using virtual reality will correlate with the quality of simulated laparoscopic ventral hernia repair. MATERIALS AND METHODS: Surgical residents (N = 37), performed 2 virtual reality perceptual-motor tasks: (1) force matching and (2) target tracking. Participants also performed a laparoscopic ventral hernia repair on a simulator and final product quality score, and endoscopic visualization errors were calculated. Correlational analysis was performed to assess the relationship between performance on virtual reality tasks and laparoscopic ventral hernia repair. RESULTS: Residents with poor performance on force matching in virtual reality-"peak deflection" (r = -0.34, P < .05) and "summation distance" (r = -0.36, P < .05)-had lower final product quality scores. Likewise, poor performance in virtual reality-based target tracking-"path length" (r = -0.49, P < .05) and "maximum distance" (r = -0.37, P < .05)-correlated with a lower final product quality score. CONCLUSION: Our findings support the notion that virtual reality could be used as a screening tool for perceptual-motor skill. Trainees identified as having poor perceptual-motor skill can benefit from focused curricula, allowing them to hone personal areas of weakness and maximize technical skill.

Shortcut assessment: Can residents' operative performance be determined in the first five minutes of an operative task?

BACKGROUND: The aim was to validate the potential use of a single, early procedure, operative task as a predictive metric for overall performance. The authors hypothesized that a shortcut psychomotor assessment would be as informative as a total procedural psychomotor assessment when evaluating laparoscopic ventral hernia repair performance on a simulator. METHODS: Using electromagnetic sensors, hand motion data were collected from 38 surgery residents during a simulated laparoscopic ventral hernia repair procedure. Three time-based phases of the procedure were defined: Early Phase (start time through completion of first anchoring suture), Mid Phase (start time through completion of second anchoring suture), and Total Operative Time. Correlations were calculated comparing time and motion metrics for each phase with the final laparoscopic ventral hernia repair score. RESULTS: Analyses revealed that execution time and motion, for the first anchoring suture, predicted procedural outcomes. Greater execution times and path lengths correlated to lesser laparoscopic ventral hernia repair scores (r = -0.56, P = .0008 and r = -0.51, P = .0025, respectively). Greater bimanual dexterity measures correlated to Greater LVH repair scores (r = + 0.47, P = .0058). CONCLUSIONS: This study provides validity evidence for use of a single, early operative task as a shortcut assessment to predict resident performance during a simulated laparoscopic ventral hernia repair procedure. With the continued development and decreasing costs of motion technology, faculty should be well-versed in the use of motion metrics for performance measurements. The results strongly support the use of dexterity and economy of motion (path length + execution time) metrics as early predictors of operative performance.

The klotho-related protein KLPH (lctl) has preferred expression in lens and is essential for expression of clic5 and normal lens suture formation.

KLPH/lctl belongs to the Klotho family of proteins. Expressed sequence tag analyses unexpectedly revealed that KLPH is highly expressed in the eye lens while northern blots showed that expression is much higher in the eye than in other tissues. In situ hybridization in mouse localized mRNA to the lens, particularly in the equatorial epithelium. Immunofluorescence detected KLPH in lens epithelial cells with highest levels in the germinative/differentiation zone. The gene for KLPH in mouse was deleted by homologous recombination. Littermate knockout (KO) and wild type (WT) mice were compared in a wide panel of pathology examinations and were all grossly normal, showing no systemic effects of the deletion. However, the lens, while superficially normal at young ages, had focusing defects and exhibited age-related cortical cataract by slit lamp examination. Whole-lens imaging showed that KO mice had disorganized lens sutures, forming a loose double-y or x instead of the tight y formation of WT. RNA-seq profiles for KO and WT littermates confirmed the absence of KLPH mRNA in KO lens and also showed complete absence of transcripts for Clic5, a protein associated with cilium/basal body related auditory defects in a mouse model. Immunofluorescence of lens epithelial flat mounts showed that Clic5 localized to cilia/centrosomes. Mice mutant for Clic5 (jitterbug) also had defective sutures. These results suggest that KLPH is required for lens-specific expression of Clic5 and that Clic5 has an important role in the machinery that controls lens fiber cell extension and organization.
