RESUMO

Patients in rural and underserved areas face significant barriers in accessing specialty care due to unavailability of services, geographic isolation, travel burden, and other cultural and socioeconomic factors.1 Pediatric dermatology is among the top three subspecialties that provides routine care for pediatric patients, however, shortage and maldistribution of pediatric dermatologists have remained a major hurdle for those living in remote and isolated areas.2 Pediatric dermatologists cluster in urban areas with high-patient volume and estimated wait times for new patients that often exceed 13 weeks, making access one of the major drivers of inequity for rural patients.2-4.

RESUMO

The coronavirus disease 2019 pandemic disrupted health care, requiring organizational leaders to act quickly to manage the health-related concerns of individuals and communities. The ability to offer a variety of digitally enabled telehealth services with 24/7 access to nurse practitioners and physician assistants allowed us to care for patients in their homes. It reduced the spread of the virus, protected our employees from further disease spread, and provided early interventions to those in need. The roles of nurse practitioner leaders, the enacted strategies, and patient outcomes demonstrate the impact of an innovative digital care delivery model on care across the continuum.

RESUMO

As antibiotic resistance continues to increase globally, there is an urgency for novel, non-antibiotic approaches to control chronic drug-resistant infections, particularly those associated with polymicrobial biofilm formation in chronic wounds. Also needed are clinically relevant polymicrobial biofilm models that can be utilized to assess the efficacy of innovative therapeutics against mature biofilms. We successfully developed a highly reproducible porcine ex vivo skin wound polymicrobial biofilm model using clinical isolates of multidrug-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and Candida albicans. This ex vivo biofilm model was then used to assess the antimicrobial and antibiofilm properties of an easily fabricated chitosan hydrogel incorporating the natural antimicrobial peptide epsilon-poly-L-lysine. Antimicrobial activity was evaluated against planktonic cultures in vitro and against mature biofilms ex vivo. The antibiofilm efficiency of the hydrogels was especially pronounced against Pseudomonas aeruginosa, whose counts were reduced by 99.98% after 2 hours in vitro and by 99.94% after treatment for 24 hours when applied to 24 hour ex vivo polymicrobial wound biofilms. The activity of the hydrogels was lower against Staphylococcus aureus and ineffective against Candida albicans. Gram, Hucker-Twort staining of paraffin sections revealed balanced polymicrobial communities in mature 48 hour untreated biofilms. Treatment of 48 or 72 hour biofilms for 2 or 3 days with hydrogels that were applied within 5 hours after inoculation resulted in an impressive 96% and 97% reduction in biofilm thickness compared to untreated biofilms, respectively (P < .001). Likewise, topical gel treatment for 24 hours reduced biofilm thickness by 84% and 70%, respectively, when applied to mature biofilms at 24 and 48 hours after inoculation (P < .001). Thus, this ex vivo wound biofilm model provides a useful means to assess the efficacy of novel treatments to prevent and eradicate polymicrobial biofilms consisting of multidrug-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and Candida albicans.

RESUMO

PURPOSE: Despite cure, adolescents and young adults (AYA) who complete cancer treatment remain at risk for numerous physical and psychological late effects. However, engagement in recommended follow-up care, knowledge of cancer treatment history and risks, and adoption of health promoting behaviors are often suboptimal. The pilot randomized controlled trial assessed the feasibility and acceptability of a text messaging intervention (THRIVE; Texting Health Resources to Inform, motiVate, and Engage) designed to promote well-being, and health knowledge and behaviors. METHODS: Sixty-one AYA who recently completed cancer therapy enrolled and were randomized to receive THRIVE (n = 31) or an AYA survivor handbook (n = 30). Participants from both groups completed baseline measures and follow-up surveys 16 weeks later. AYA randomized to THRIVE received one to two health-related text messages per day over 16 weeks. RESULTS: THRIVE demonstrated a high level of acceptability and feasibility. Exploratory analyses highlighted promising improvements in knowledge, fruit/vegetable intake, and perceptions of health vulnerability. CONCLUSIONS: Text messaging is an acceptable and feasible intervention approach for improving well-being and health of AYA survivors. Future research is needed to test the impact of text messaging in a larger trial, including whether or not such an intervention can improve clinical outcomes, such as survivors' engagement in follow-up care.

RESUMO

BACKGROUND: Minimal research exists on how engagement, burnout, work-family balance, and job stressors impact advanced practice nurses and physician assistants, collectively referred to advanced practice providers (APPs). PURPOSE: To investigate the interrelationships among burnout, job stressors, work-family balance, and engagement with APPs. METHODS: An online questionnaire was distributed to APPs working in four healthcare systems. A total of 1,216 APPs completed the survey. A hypothesized model was tested using structural equation modeling. FINDINGS: There was a high correlation of job stressors with development of burnout. A significant negative effect between job stress and work engagement was supported; however, indirect effects of stress through job burnout had a stronger impact on work engagement. Higher levels of work-family balance contributed to a lower level of stress experienced by providers. DISCUSSION: Organizational leaders desiring to improve employee engagement and reduce burnout need to focus on the significance of work-family balance to job stressors.

RESUMO

BACKGROUND: Studies examining the association between hyperoxia exposure after resuscitation from cardiac arrest and clinical outcomes have reported conflicting results. Our objective was to test the hypothesis that early postresuscitation hyperoxia is associated with poor neurological outcome. METHODS: This was a multicenter prospective cohort study. We included adult patients with cardiac arrest who were mechanically ventilated and received targeted temperature management after return of spontaneous circulation. We excluded patients with cardiac arrest caused by trauma or sepsis. Per protocol, partial pressure of arterial oxygen (Pao2) was measured at 1 and 6 hours after return of spontaneous circulation. Hyperoxia was defined as a Pao2 >300 mm Hg during the initial 6 hours after return of spontaneous circulation. The primary outcome was poor neurological function at hospital discharge, defined as a modified Rankin Scale score >3. Multivariable generalized linear regression with a log link was used to test the association between Pao2 and poor neurological outcome. To assess whether there was an association between other supranormal Pao2 levels and poor neurological outcome, we used other Pao2 cut points to define hyperoxia (ie, 100, 150, 200, 250, 350, 400 mm Hg). RESULTS: Of the 280 patients included, 105 (38%) had exposure to hyperoxia. Poor neurological function at hospital discharge occurred in 70% of patients in the entire cohort and in 77% versus 65% among patients with versus without exposure to hyperoxia respectively (absolute risk difference, 12%; 95% confidence interval, 1-23). Hyperoxia was independently associated with poor neurological function (relative risk, 1.23; 95% confidence interval, 1.11-1.35). On multivariable analysis, a 1-hour-longer duration of hyperoxia exposure was associated with a 3% increase in risk of poor neurological outcome (relative risk, 1.03; 95% confidence interval, 1.02-1.05). We found that the association with poor neurological outcome began at ≥300 mm Hg. CONCLUSIONS: Early hyperoxia exposure after resuscitation from cardiac arrest was independently associated with poor neurological function at hospital discharge.

RESUMO

BACKGROUND: Reports of acceptability of psychosocial screening are limited, and the utility of screening in identifying risk factors for health-related quality of life (HRQL) of children with cancer has not been established. This study aimed to assess acceptability of screening for parents and evaluate associations between family risk factors and patient HRQL in the first year post-diagnosis. PROCEDURE: Sixty-seven parents of children with cancer completed the Psychosocial Assessment Tool (family risk), Distress Thermometer (caregiver distress), Posttraumatic Stress Disorder Checklist-Civilian 6 (caregiver traumatic stress), PedsQL 4.0 (parent-proxy report of patient HRQL) and four acceptability questions via a tablet (iPad). RESULTS: Patients (Mage = 9.5 SD = 5.5 years) were equally distributed across major pediatric cancer diagnoses. The majority of parents endorsed electronic screening as acceptable (70%-97%). Patient gender, diagnosis, intensity of treatment and time since diagnosis were not significantly correlated with family risk, caregiver distress, traumatic stress, or patient HRQL. The full regression model predicting total HRQL was significant (R2 = .42, F(4,64) = 10.7, p = .000). Age (older) was a significant covariate, family risk and caregiver distress were significant independent predictors of poorer total HRQL. The full regression models for physical and psychosocial HRQL were significant; age and caregiver distress were independent predictors of physical HRQL, and age and family risk were independent predictors of psychosocial HRQL. CONCLUSIONS: Screening is acceptable for families and important for identifying risk factors associated with poorer patient HRQL during childhood cancer treatment. Targeted interventions addressing family resource needs as well as parent distress identified through screening may be effective in promoting patient HRQL. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

Ensuring clinical faculty have adequate training and resources in any educational program is paramount for the learner's success. Transition-to-practice programs are no different, and one program has found success in the implementation of a formalized faculty development program to support educators of a multisite, multispecialty advanced practice provider fellowship.

RESUMO

OBJECTIVE: Amenorrhoea and low bone density are common in excessive exercisers, yet endocrine factors that differentiate adolescent amenorrhoeic exercisers (AE) from eumenorrhoeic exercisers (EE) are unclear. We have previously reported that high ghrelin and low leptin predict lower LH secretion in AE. Leptin and ghrelin impact cortisol secretion, and hypercortisolaemia can inhibit LH pulsatility. We hypothesized that higher cortisol secretion in young endurance weight-bearing AE compared with EE and nonexercisers predicts lower LH secretion, lower levels of a bone formation marker and higher levels of a bone resorption marker. DESIGN: Cross-sectional. SUBJECTS: We studied 21 AE, 18 EE and 20 nonexercisers aged 14-21 years (BMI 10th-90th%iles). MEASUREMENTS: Subjects underwent frequent sampling (11 p.m. to 7 a.m.) to assess cortisol, ghrelin, leptin and LH secretory dynamics. Fasting levels of a bone formation (P1NP) and bone resorption (CTX) marker were measured. RESULTS: BMI did not differ among groups. Cortisol pulse amplitude, mass, half-life and area under the curve (AUC) were highest in AE (P = 0.04, 0.007, 0.04 and 0.003) and were associated inversely with fat mass (r = -0.29, -0.28 and -0.35, P = 0.03, 0.04 and 0.007). We observed inverse associations between cortisol and LH AUC (r = -0.36, P = 0.008), which persisted after controlling for fat mass, leptin and ghrelin AUC. Cortisol correlated positively with CTX in EE and inversely with P1NP in nonexercisers. CONCLUSIONS: Higher cortisol secretion in AE compared with EE and nonexercisers is associated with lower LH secretion. Effects of leptin and ghrelin on LH secretion may be mediated by increased cortisol.

RESUMO

INTRODUCTION: Because antibiotic resistance is increasing worldwide and the leading cause of death in burn patients is an infection, an urgent need exists for nonantibiotic approaches to eliminate multidrug-resistant bacteria from burns to prevent their systemic dissemination and sepsis. We previously demonstrated the significant antibiofilm activity of a chitosan (CS) hydrogel containing the antimicrobial peptide epsilon-poly-l-lysine (EPL) against multidrug-resistant Pseudomonas aeruginosa using ex vivo porcine skin. In this study, we evaluated the in vivo antibacterial efficacy of a CS/EPL hydrogel against P. aeruginosa in a murine burn wound infection model. MATERIALS AND METHODS: Full-thickness burns were created on the dorsum using a heated brass rod and were inoculated with bioluminescent, biofilm-forming P. aeruginosa (Xen41). Mice were treated with CS/EPL, CS, or no hydrogel applied topically 2 or 24 hours after inoculation to assess the ability to prevent or eradicate existing biofilms, respectively. Dressing changes occurred daily for 3 days, and in vivo bioluminescence imaging was performed to detect and quantitate bacterial growth. Blood samples were cultured to determine systemic infection. In vitro antibacterial activity and cytotoxicity against human primary dermal fibroblasts, keratinocytes, and mesenchymal stem cells were also assessed. RESULTS: CS/EPL treatment initiated at early or delayed time points showed a significant reduction in bioluminescence imaging signal compared to CS on days 2 and 3 of treatment. Mice administered CS/EPL had fewer bloodstream infections, lower weight loss, and greater activity than the untreated and CS groups. CS/EPL reduced bacterial burden by two orders of magnitude in vitro and exhibited low cytotoxicity against human cells. CONCLUSION: A topical hydrogel delivering the antimicrobial peptide EPL demonstrates in vivo efficacy to reduce but not eradicate established P. aeruginosa biofilms in infected burn wounds. This biocompatible hydrogel shows promise as an antimicrobial barrier dressing for the sustained protection of burn wounds from external bacterial contamination.

RESUMO

Amenorrhea is common in young athletes and is associated with low fat mass. However, hormonal factors that link decreased fat mass with altered gonadotropin pulsatility and amenorrhea are unclear. Low levels of leptin (an adipokine) and increased ghrelin (an orexigenic hormone that increases as fat mass decreases) impact gonadotropin pulsatility. Studies have not examined luteinizing hormone (LH) secretory dynamics in relation to leptin or ghrelin secretory dynamics in adolescent and young adult athletes. We hypothesized that 1) young amenorrheic athletes (AA) would have lower LH and leptin and higher ghrelin secretion than eumenorrheic athletes (EA) and nonathletes and 2) higher ghrelin and lower leptin would be associated with lower LH secretion. This was a cross-sectional study. We examined ghrelin and leptin secretory patterns (over 8 h, from 11 PM to 7 AM) in relation to LH secretory patterns in AA, EA, and nonathletes aged 14-21 yr. Ghrelin and leptin were assessed every 20 min and LH every 10 min. Groups did not differ for age, bone age, or BMI. However, fat mass was lower in AA than in EA and nonathletes. AA had lower LH and higher ghrelin pulsatile secretion and AUC than nonathletes and lower leptin pulsatile secretion and AUC than EA and nonathletes. Percent body fat was associated positively with LH and leptin secretion and inversely with ghrelin. In a regression model, ghrelin and leptin secretory parameters were associated independently with LH secretory parameters. We conclude that higher ghrelin and lower leptin secretion in AA related to lower fat mass may contribute to altered LH pulsatility and amenorrhea.

RESUMO

Significant controversy over the environmental and public health impact of depleted uranium use in the Gulf War and the war in the Balkans has prompted the investigation and use of other materials including heavy metal tungsten alloys (HMTAs) as nontoxic alternatives. Interest in the health effects of HMTAs has peaked since the recent discovery that rats intramuscularly implanted with pellets containing 91.1% tungsten/6% nickel/2.9% cobalt rapidly developed aggressive metastatic tumors at the implantation site. Very little is known, however, regarding the cellular and molecular mechanisms associated with the effects of inhalation exposure to HMTAs despite the recognized risk of this route of exposure to military personnel. In the current study military-relevant metal powder mixtures consisting of 92% tungsten/5% nickel/3% cobalt (WNiCo) and 92% tungsten/5% nickel/3% iron (WNiFe), pure metals, or vehicle (saline) were instilled intratracheally in rats. Pulmonary toxicity was assessed by cytologic analysis, lactate dehydrogenase activity, albumin content, and inflammatory cytokine levels in bronchoalveolar lavage fluid 24h after instillation. The expression of 84 stress and toxicity-related genes was profiled in lung tissue and bronchoalveolar lavage cells using real-time quantitative PCR arrays, and in vitro assays were performed to measure the oxidative burst response and phagocytosis by lung macrophages. Results from this study determined that exposure to WNiCo and WNiFe induces pulmonary inflammation and altered expression of genes associated with oxidative and metabolic stress and toxicity. Inhalation exposure to both HMTAs likely causes lung injury by inducing macrophage activation, neutrophilia, and the generation of toxic oxygen radicals.

RESUMO

OBJECTIVE: The objective of the study was to compare the influence of collagen-coated vs uncoated polypropylene meshes on the expression of genes critical for wound healing. STUDY DESIGN: In 54 rats, abdominal wall defects were created, repaired by polypropylene sutures, and covered by an overlay of coated polypropylene (n = 20), uncoated polypropylene (n = 18), or no mesh (n = 16). Explants were harvested 7 or 90 days after repair and divided for histological, immunohistochemical, and messenger ribonucleic acid (mRNA) analyses. Real-time quantitative polymerase chain reaction arrays were used to profile the expression of 84 genes at the tissue-mesh interface. RESULTS: One week after implantation, coated mesh elicited a slightly greater inflammatory response and increased mRNA expression of 4 proinflammatory cytokines compared with uncoated mesh. Both materials, however, induced a comparable expression of cytokines and matrix metalloproteinases relative to suture repair 90 days after implantation. CONCLUSION: Collagen-coated polypropylene mesh induces elevated inflammatory cytokine expression compared with uncoated mesh early in the healing process, but the response to both meshes is similar 90 days after implantation.

RESUMO

INTRODUCTION AND HYPOTHESIS: The objective of this study was to measure the effects of pregnancy and parturition on pelvic floor muscles and pelvic organ support. METHODS: Levator ani, obturator internus, and coccygeus (COC) muscle volumes and contrast uptake were assessed by MRI of seven females prior to pregnancy, 3 days, and 4 months postpartum. Bladder neck and cervix position were measured dynamically with abdominal squeezing. RESULTS: The sides of three paired muscles were similar (p > 0.66). COC volumes were greater (p < 0.004) after parturition than before pregnancy or after recovery. COC contrast uptake increased (p < 0.02) immediately after delivery. Bladder neck position both in the relaxed state and abdominal pressure descended (p < 0.04) after delivery and descended further (p < 0.001) after recovery. Cervical position in the relaxed state before delivery was higher (p < 0.001) than postpartum but was unchanged (p = 0.50) with abdominal pressure relative to delivery. CONCLUSION: In squirrel monkeys, coccygeus muscles demonstrate the greatest change related to parturition, and parturition-related bladder neck descent seems permanent.

RESUMO

Mesenchymal stem cells (MSCs) help fight infection by promoting direct bacterial killing or indirectly by modulating the acute phase response, thereby decreasing tissue injury. Recent evidence suggests that extracellular vesicles (EVs) released from MSCs retain antimicrobial characteristics that may be enhanced by pretreatment of parent MSCs with the toll-like receptor 3 (TLR3) agonist poly(I:C). Our aim was to determine whether poly(I:C) priming can modify EV content of miRNAs and/or proteins to gain insight into the molecular mechanisms of their enhanced antimicrobial function. Human bone marrow-derived MSCs were cultured with or without 1 µg/ml poly(I:C) for 1 h and then conditioned media was collected after 64 h of culture in EV-depleted media. Mass spectrometry and small RNA next-generation sequencing were performed to compare proteomic and miRNA profiles. Poly(I:C) priming resulted in 49 upregulated EV proteins, with 21 known to be important in host defense and innate immunity. In contrast, EV miRNA content was not significantly altered. Functional annotation clustering analysis revealed enrichment in biological processes and pathways including negative regulation of endopeptidase activity, acute phase, complement and coagulation cascades, innate immunity, immune response, and Staphylococcus aureus infection. Several antimicrobial peptides identified in EVs remained unaltered by poly(I:C) priming, including dermcidin, lactoferrin, lipocalin 1, lysozyme C, neutrophil defensin 1, S100A7 (psoriasin), S100A8/A9 (calprotectin), and histone H4. Although TLR3 activation of MSCs improves the proteomic profile of EVs, further investigation is needed to determine the relative importance of particular functional EV proteins and their activated signaling pathways following EV interaction with immune cells.

RESUMO

This study sought to examine the experiences of advanced practice providers (APPs) as an approach to inform the development of formalized programs for transition into practice and to compare APP (N = 122) and physician (N = 84) perceptions of the novice practitioners' acclimation into a provider role within the first year of practice. Using a cross-sectional survey design, two separate web-based questionnaires were distributed to APPs and physicians. The APPs' perspectives echoed findings of earlier studies with regard to perceived confidence, feelings of anxiety/fear, and inadequacy. In 16 of 23 paired items, physicians and APPs had similar perspectives about confidence/competence after orientation. Significant differences in their perceptions included amount of physician support, time management, length of time to become a fully functional APP, and independence. Better understanding of the perceptions of APPs and physicians can augment APP preparation for a shifting workforce composition and team-based, interprofessional practice designed to meet the population's health care needs.

RESUMO

BACKGROUND: Gaps in research persist related to practitioners' resilience, although much has been written about the need for strategies to strengthen personal resilience. PURPOSE: The study's purpose was to examine practice-level (quality of physician relationship, physician presence, and autonomy) and individual factors and how they affect resilience. METHODOLOGY: An online survey invited advanced practice registered nurses (APRNs) and physician assistants (PAs) from four states to participate in a cross-sectional study. Hierarchical ordinary least squares regression was used to test the impact of main effect variables in the context of identified control variables. SAMPLE: A sample of 1,138 APRNs and PAs completed the survey questions. RESULTS: Findings from the covariate model (model 1) and the main effect model (model 2) show that both models were significant at the p < .01 level, with the adjusted R2 differing from 0.02 to 0.13, respectively. Regression results show a significant positive association between quality of the physician relationship and APRN/PA resilience (b = 0.09, p < .01). A negative association between the lack of autonomy and higher levels of resilience (b = -0.14, p < .01) was also demonstrated. CONCLUSIONS: Advanced practice registered nurse/PA resilience is affected by both practice-level and personal factors, suggesting that workplace interventions could increase resilience. IMPLICATIONS FOR PRACTICE: Work environments allowing APRNs and PAs to function autonomously and with professional support from physician colleagues are favorable contributors to their resilience. Future studies need to investigate the meaning of physician presence/availability and organizational interventions that extend beyond individual resilience.

RESUMO

Unresolved work stress contributes to burnout, compassion fatigue, disengagement, and other work-contextualized factors. The impact of occupational stressors extends to the organization in a negative fashion as well. In 2017, advanced practice providers (APPs) from four health systems, including nurse practitioners, clinical nurse specialists, nurse midwives, nurse anesthetists, and physician assistants, participated in a quantitative online cross-sectional survey; 754 participants responded to a free-text question related to work stress and work-family balance. Suggested organizational strategies were ordered into 29 codes, 10 subthemes, and four main themes: "reduce job stressors," "improve leadership and operations," "promote APP well-being," and "maintain the status quo." Findings are consistent with other research related to occupational stress with many of the reported strategies considered as evidence-based. Targeted interventions for reducing job stress will need to include improved autonomy for APPs, role delineation, support for work-family balance, and better communication as part of management practices.

RESUMO

BACKGROUND: Preceptors are essential in advanced practice registered nurse (APRN) and physician assistant (PA) fellowships; however, no tools exist for fellows to evaluate their preceptor. PURPOSE: The study's purpose was to examine the use of a modified preceptor evaluation tool (PET) in a new population APRNs and PAs who participated in a formalized postgraduate fellowship program. METHODOLOGICAL ORIENTATION: A qualitative study involving cognitive interviewing methods was used to evaluate original and modified items of the PET as a means to determine face validity. Over a period of 19 months, five different focus groups were conducted. Study participants completed an independent analysis of the tool prior to engaging in a focus group discussion. Further testing of new items was performed using the last two focus group cohorts and achieved data saturation. SAMPLE: The sample included 23 fellows who had completed an acute, ambulatory, or primary care yearlong fellowship. More than half of the fellows ranged in age from <30 to 40 years. CONCLUSIONS: All original 19 items were retained, with the majority (79%) requiring slight modifications. Using feedback from fellows, 10 items were added to the final version, including two open-ended questions. The new items added a focus on preceptors' ability to foster domains of professional growth in the fellows' provider role. IMPLICATIONS FOR PRACTICE: This newly developed tool with face validity provides a new mechanism for preceptor evaluation by APRN and PA fellows. Additional research is needed with larger groups of fellows as a means to establish the tool's psychometric properties.

RESUMO

BACKGROUND: The COVID-19 global pandemic brought mandatory shelter-in-place orders, disrupting traditional face-to-face teaching methods for advanced practice fellowship programs nationally, creating a challenge for fellowship program directors to preserve curriculum using nontraditional methods. METHOD: Using a variety of both web-based and app-based virtual platforms, a nationally accredited fellowship program converted traditional in-seat learning modalities to elearning platforms using both synchronous and asynchronous education. RESULTS: Preliminary data indicate that knowledge acquisition and perceived fellow satisfaction are preserved despite the abrupt change to program delivery. Programmatic modifications were submitted to the American Nurse Credentialing Center for compliance and deemed as creative, innovative, and collaborative. CONCLUSION: Curriculum for advanced practice fellowship programs can be favorably converted to elearning using virtual platforms during a crisis. Through prompt reevaluation and restructuring, virtual platforms can replace in-seat didactic lectures, patient case studies, mentoring, and even simulation, while ensuring program continuation and compliance with accreditation standards.
