RESUMO

The ANCC Magnet Recognition Program's® mission and vision is to continually elevate patient care and transform healthcare globally through an environment where nurses and the interprofessional team flourish. Reflecting the larger shifts in the healthcare delivery system from inpatient to ambulatory care settings, the Commission on Magnet® continues to emphasize the contributions of nurses in ambulatory care settings in the 2023 Magnet Application Manual®. This Magnet® Perspectives column will discuss the valuable role of ambulatory care nurses across the continuum of care and review new requirements in the 2023 Magnet Application Manual for measurement of nurse-sensitive outcomes in the ambulatory care setting using nationally benchmarked measures. In addition, potential sources of nationally benchmarked ambulatory data and selection of ambulatory care outcome measures will be discussed.

RESUMO

OBJECTIVE: The aim of this study was to assess the quality of free-to-access videos on oral biopsy procedures on the YouTube platform. MATERIALS AND METHODS: We conducted a search on YouTube using the term "oral biopsy" and selected the first 100 videos in order of relevance. The following exclusion criteria were applied: language other than English, videos that did not cover oral biopsy techniques, videos on nonhuman specimens, postoperative instructions, personal experiences, exfoliative cytology, or "brush biopsy." Forty-seven selected videos were classified based on their duration, country of origin, date of upload to the system, author, information source and number of views, and likes and dislikes. Video quality was analyzed using DISCERN, the Global Quality Scale (GQS), and the Video Information and Quality Index (VIQI). RESULTS: The majority (78.7%) of analyzed videos were uploaded by dentists, originating from India (48.9%), with a mean duration of 11.8 min (SD, 20.4), with 104.5 likes (SD, 186.4) and 7.1 dislikes (SD, 10.55). The mean values for DISCERN, GQS, and VIQI were 1.3 (SD, 0.52), 2.1 (SD, 1.04), and 9.62 (SD, 1.69), respectively. CONCLUSION: The majority of videos on oral biopsy published on YouTube are of low quality.

RESUMO

BACKGROUND: The persistence of racial/ethnic inequities in rates of engagement along the HIV care continuum signals the need for novel approaches. We developed six behavioral intervention components for use in an optimization trial, grounded in a model that integrates critical race theory, harm reduction, and self-determination theory, designed to address various barriers that African American/Black and Latino persons living with HIV (PLWH) experience to the HIV care continuum. The components were: health education, motivational interviewing sessions, pre-adherence skill building, peer mentorship, focused support groups, and navigation. The present qualitative exploratory study describes participants' perspectives on the components' acceptability, feasibility, and impact. METHODS: Participants were African American/Black and Latino PLWH poorly engaged in HIV care and with non-suppressed HIV viral load in New York City. From a larger trial, we randomly selected 46 participants for in-depth semi-structured interviews. Interviews were audio-recorded and transcribed verbatim, and data were analyzed using directed content analysis. Quantitative data on sociodemographic and background characteristics and components' acceptability and feasibility were also collected. RESULTS: On average, participants were 49 years old and had lived with HIV for 19 years. Most were cisgender-male and African American/Black. Participants reported a constellation of serious social and structural challenges to HIV management including chronic poverty, unstable housing, and stigma. Across components, a non-judgmental and pressure-free approach and attention to structural and cultural factors were seen as vital to high levels of engagement, but lacking in most medical/social service settings. Prominent aspects of individual components included establishing trust (health education); developing intrinsic motivation, goals, and self-reflection (motivational interviewing sessions); learning/practicing adherence strategies and habits (pre-adherence skill building); reducing social isolation via peer role models (peer mentorship); reflecting on salient goals and common challenges with peers without stigma (focused support groups); and circumventing structural barriers to HIV management with support (navigation). Components were found acceptable and feasible. Findings suggested ways components could be improved. CONCLUSIONS: The present study advances research on interventions for African American/Black and Latino PLWH, who experience complex barriers to engagement along the HIV care continuum. Future study of the components is warranted to address racial/ethnic health inequities in HIV.

RESUMO

BACKGROUND: There are three different approaches set forth by the Committee on the Fetus and Newborn (COFN) for managing asymptomatic neonates born to mothers with inadequate intrapartum antibiotic prophylaxis (IAP) for early-onset Group B Strep (GBS) infection. The first approach is that of categorical risk factor assessments, and recommends that asymptomatic infants born to afebrile mothers with inadequate IAP for GBS be monitored with clinical observation for 36-48 hours. The second approach recommends serial physical examinations and vital signs for 36-48 hours to closely monitor changes in clinical condition for all patients. The Kaiser Permanente EOS risk calculator (SRC) is an example of the third approach, a multivariate risk assessment, and it takes into consideration several perinatal risk factors. This multivariate risk assessment then provides recommendations for reassessment and management based on presume risk of the infant developing or having Early Onset Sepsis (EOS). The aim of our study was to compare these three recently published recommendations from the COFN for the management of asymptomatic neonates born to afebrile mothers with inadequate IAP for GBS. STUDY DESIGN: This is a retrospective study of asymptomatic neonates with gestational age ≥35 weeks born to afebrile mothers with indicated inadequate IAP for GBS between April 2017 and July 2020. Management recommendations of the SRC were compared to the recommendations of categorical risk assessment and risk assessment based on clinical condition. RESULTS: A total of 7,396 infants were born during the study period, 394 (5.3%. to mothers with inadequate IAP. Recommendations for these infants according to both the categorical risk factor guideline and the clinical condition guideline include extended, close observation. However, the SRC recommended routine newborn care for 99.7%.f these infants. None of the infants developed EOS. CONCLUSION: The SRC recommend routine neonatal care without enhanced and prolonged observation for nearly all asymptomatic infants born to afebrile mothers with inadequate IAP. As none of the infants in this cohort had EOS, further studies in a larger cohort are needed to establish the safety of SRC in neonates born to mothers with inadequate IAP.

RESUMO

Neutrophil extracellular traps contribute to lung injury in cystic fibrosis and asthma, but the mechanisms are poorly understood. We sought to understand the impact of human NETs on barrier function in primary human bronchial epithelial and a human airway epithelial cell line. We demonstrate that NETs disrupt airway epithelial barrier function by decreasing transepithelial electrical resistance and increasing paracellular flux, partially by NET-induced airway cell apoptosis. NETs selectively impact the expression of tight junction genes claudins 4, 8 and 11. Bronchial epithelia exposed to NETs demonstrate visible gaps in E-cadherin staining, a decrease in full-length E-cadherin protein and the appearance of cleaved E-cadherin peptides. Pretreatment of NETs with alpha-1 antitrypsin (A1AT) inhibits NET serine protease activity, limits E-cadherin cleavage, decreases bronchial cell apoptosis and preserves epithelial integrity. In conclusion, NETs disrupt human airway epithelial barrier function through bronchial cell death and degradation of E-cadherin, which are limited by exogenous A1AT.

RESUMO

This guideline on mucous membrane pemphigoid (MMP) has been elaborated by the Task Force for Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology (EADV) with a contribution of physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline encompassing a systematic review of the literature until June 2019 in the MEDLINE and EMBASE databases. This first part covers methodology, the clinical definition of MMP, epidemiology, MMP subtypes, immunopathological characteristics, disease assessment and outcome scores. MMP describes a group of autoimmune skin and mucous membrane blistering diseases, characterized by a chronic course and by predominant involvement of the mucous membranes, such as the oral, ocular, nasal, nasopharyngeal, anogenital, laryngeal and oesophageal mucosa. MMP patients may present with mono- or multisite involvement. Patients' autoantibodies have been shown to be predominantly directed against BP180 (also called BPAG2, type XVII collagen), BP230, laminin 332 and type VII collagen, components of junctional adhesion complexes promoting epithelial stromal attachment in stratified epithelia. Various disease assessment scores are available, including the Mucous Membrane Pemphigoid Disease Area Index (MMPDAI), the Autoimmune Bullous Skin disorder Intensity Score (ABSIS), the 'Cicatrising Conjunctivitis Assessment Tool' and the Oral Disease Severity Score (ODSS). Patient-reported outcome measurements (PROMs), including DLQI, ABQOL and TABQOL, can be used for assessment of quality of life to evaluate the effectiveness of therapeutic interventions and monitor disease course.

RESUMO

This guideline has been initiated by the task force Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology, including physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline that systematically reviewed the literature on mucous membrane pemphigoid (MMP) in the MEDLINE and EMBASE databases until June 2019, with no limitations on language. While the first part of this guideline addressed methodology, as well as epidemiology, terminology, aetiology, clinical presentation and outcome measures in MMP, the second part presents the diagnostics and management of MMP. MMP should be suspected in cases with predominant mucosal lesions. Direct immunofluorescence microscopy to detect tissue-bound IgG, IgA and/or complement C3, combined with serological testing for circulating autoantibodies are recommended. In most patients, serum autoantibodies are present only in low levels and in variable proportions, depending on the clinical sites involved. Circulating autoantibodies are determined by indirect IF assays using tissue substrates, or ELISA using different recombinant forms of the target antigens or immunoblotting using different substrates. The major target antigen in MMP is type XVII collagen (BP180), although in 10-25% of patients laminin 332 is recognized. In 25-30% of MMP patients with anti-laminin 332 reactivity, malignancies have been associated. As first-line treatment of mild/moderate MMP, dapsone, methotrexate or tetracyclines and/or topical corticosteroids are recommended. For severe MMP, dapsone and oral or intravenous cyclophosphamide and/or oral corticosteroids are recommended as first-line regimens. Additional recommendations are given, tailored to treatment of single-site MMP such as oral, ocular, laryngeal, oesophageal and genital MMP, as well as the diagnosis of ocular MMP. Treatment recommendations are limited by the complete lack of high-quality randomized controlled trials.

RESUMO

INTRODUCTION: This study investigates instances of elevated radiation dose on a radiation tracking system to determine their aetiologies. It aimed to investigate the impact of radiographer feedback on these alerts. METHODS: Over two six-month periods 11,298 CT examinations were assessed using DoseWatch. Red alerts (dose length products twice the median) were identified and two independent reviewers established whether alerts were true (unjustifiable) or false (justifiable). During the second time period radiographers used a feedback tool to state the cause of the alert. A Chi-Square test was used to assess whether red alert incidence decreased following the implementation of radiographer feedback. RESULTS: There were 206 and 357 alerts during the first and second time periods, respectively. These occurred commonly with CT pulmonary angiography, brain, and body examinations. Procedural documentation errors and patient size accounted for 57% and 43% of false alerts, respectively. Radiographer feedback was provided for 17% of studies; this was not associated with a significant change in the number of alerts, but the number of true alerts declined (from 7 to 3) (χ2 = 4.14; p = 0.04). CONCLUSION: Procedural documentation errors as well as patient-related factors are associated with false alerts in DoseWatch. Implementation of a radiographer feedback tool reduced true alerts. IMPLICATIONS FOR PRACTICE: The implementation of a radiographer feedback tool reduced the rate of true dose alerts. Low uptake with dose alert systems is an issue; the workflow needs to be considered to address this.

RESUMO

BACKGROUND: A core outcome set (COS) represents the agreed minimum set of domains and measurement instruments that should be measured and reported in any clinical trial for a given condition. In BMS randomized controlled trials (RCTs), the outcomes identified in the existing literature regarding the efficacy of therapeutic interventions are numerous and diverse. Although the standardized IMMPACT core outcome domains has been developed for measurement of outcomes in chronic pain RCTs, no BMS-specific COS have been adopted and validated. With the evolving landscape of BMS management end points and the development of new therapies, a consensus on a COS for use in future BMS trials is paramount to reduce heterogeneity in outcome reporting. The aim of this study was to reach a consensus for adopting the standardized Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) outcome domains, and their tools of assessment, for burning mouth syndrome (BMS) clinical trials and clinical practice. METHODS: A BMS-specific COS will be developed using the method recommended by the Core Outcome Measures in Effective Trials (COMET) initiative (Registration: http://www.comet-initiative.org/studies/details/1357 ). Selection of questionnaire outcome measures was informed by the IMMPACT consensus and previous systematic review of RCTs in BMS conducted by the consortium. An international group of clinicians and researchers will be invited to participate in several rounds of a Delphi survey. A consensus meeting will be held with the objective of ratifying the outcomes for inclusion in the COS. A finalized COS explanatory document will be drafted, including all outcomes and measurements as determined by the Delphi rounds and consensus meeting. DISCUSSION: A COS for the management of BMS will improve the quality of future RCTs, reduce outcome reporting heterogeneity, and facilitate more vigorous data synthesis of management interventions for systematic reviews and meta-analysis. This would ensure enhanced quality evidence for clinical management of the condition.

RESUMO

Ascher's syndrome is a rare, benign entity with just over 100 reported cases. The condition is characterised by a 'double' upper lip, blepharochalasis and non-toxic thyroid enlargement. It presents before the age of 20 years in the majority of cases and shows no racial or gender differences. While the exact cause is unknown, hormonal dysfunction and autosomal dominant inheritance have been suggested as possible aetiological factors. We present two cases of Ascher's syndrome referred for investigation of lip swelling.

RESUMO

Human leukocyte antigens (HLA) are present on the surface of all nucleated cells, with the level of expression dependent on the particular HLA locus, the cell type and cellular activation state. Human umbilical vein endothelial cells (HUVECs) are easily isolated from umbilical cords and may aid our understanding of HLA expression on the vascular endothelium in the setting of transplantation. Endothelial cells on the donor-recipient interface form the barrier between transplanted organs and the host immune system. Increased knowledge of the variation in levels of individual HLA specificities may inform the assessment of transplant risk. HUVECs from 48 full term babies born consecutively following planned caesarean section were isolated, HLA typed and grown on gelatin coated culture wells. Once confluent, cells were stimulated with optimal concentrations of the cytokines TNF-α and IFN-γ for 24 hours and HLA-C expression on both unstimulated and stimulated cells was quantified by flow cytometry using the fluorescent labelled monoclonal antibody DT-9 PE. Unstimulated HLA-C expression varied by over 60% between allotypes (ANOVA, P = .004). Following stimulation, HLA-C levels increased over 15-fold and showed the same variation of expression between allotypes (P < .001). Cell surface HLA-C expression increases between 500% and 3125%, after stimulation for 24 hours. HLA-C level varies between allotypes and cells expressing more HLA-C at baseline tended to have corresponding higher levels of HLA-C following cytokine stimulation (Pearson's correlation coefficient between unstimulated and stimulated expression, P = .002).

RESUMO

Transplant rejection occurs following recipient recognition of mismatched HLA on donor tissue, but active rejection is dependent not only upon the severity of the T cell or alloantibody response, but also upon the cell surface expression of target HLA molecules. To investigate the variation in HLA expression using a model of endothelium, human umbilical vein endothelial cell (HUVEC) cultures were generated from 48 umbilical cords donated consecutively following planned caesarean section. HUVECs were stimulated using the cytokines tumour necrosis factor alpha and interferon gamma and HLA expression of unstimulated and stimulated cells determined using flow cytometry. HLA-A2, HLA-A3 and HLA-C antigens all showed a modest increase in expression for 12 hours post cell activation, followed by a more pronounced response over the next 24 to 36 hours. Each of these antigens increased by up to 40 times over unstimulated levels and in addition cells homozygous for specific HLA antigens on average had twice the amount of antigen expressed compared with cells heterozygous for that antigen, both when unstimulated and following cytokine stimulation. Cell activation is an important consideration in the assessment of transplant risk and may help progress towards understanding why rejection does not always occur in the presence of significant donor specific antibody. This data also confirms guidelines for transplantation, which recommend doubling the specific antibody level when considering immunological risk for homozygous donors.

RESUMO

Background: Care transitions from the hospital to hospice are a difficult time, and gaps during this transitions could cause poor care experiences and outcomes. However, little is known about what gaps exist in the hospital-to-hospice transition. Objectives: To understand the process of hospital-to-hospice transition and identify common gaps in the transition that result in unsafe or poor patient and family caregiver experiences. Design: We conducted a qualitative descriptive study using semistructured interviews with health care workers who are directly involved in hospital-to-hospice transitions. Participants were asked to describe the common practice of discharging patients to hospice or admitting patients from a hospital, and share their observations about hospital-to-hospice transition gaps. Setting/Subjects: Fifteen health care workers from three hospitals and three hospice programs in Portland, Oregon. Measurements: All interviews were audio recorded and analyzed using qualitative descriptive methods to describe current practices and identify gaps in hospital-to-hospice transitions. Results: Three areas of gaps in hospital-to-hospice transitions were identified: (1) low literacy about hospice care; (2) changes in medications; and (3) hand-off information related to daily care. Specific concerns included hospital providers giving inaccurate descriptions of hospice; discharge orders not including comfort medications for the transition and inadequate prescriptions to manage medications at home; and lack of information about daily care hindering smooth transition and continuity of care. Conclusion: Our findings identify gaps and suggest opportunities to improve hospital-to-hospice transitions that will serve as the basis for future interventions to design safe and high-quality hospital-to-hospice care transitions.

RESUMO

BACKGROUND: Accepted 'standard practice' for the diagnosis of immunobullous disease is a perilesional sample for direct immunofluorescence (DIF). OBJECTIVES: To compare diagnostic outcomes of a normal buccal punch biopsy (NBPB) with a perilesional biopsy (PLB) for mucous membrane pemphigoid (MMP) and pemphigus vulgaris (PV). METHODS: A retrospective analysis of 251 DIF-positive patients with MMP and 77 DIF-positive patients with PV was undertaken. Parameters analysed included the intraoral sites of involvement and histopathological, DIF and indirect immunofluorescence (IIF) findings. RESULTS: For MMP, PLB was positive in 134 of 143 (93·7%) samples, compared with 129 of 144 (89·6%) by NBPB. The diagnostic sensitivities for PLB (81%, 39 of 48) and NBPB (77%, 37 of 48) among 48 patients who underwent both techniques were not significantly different (P = 0·62). In gingival-only MMP, PLB was positive in 63 of 69 (91%) and NBPB was positive in 63 of 75 (84%). For multisite MMP, PLB was positive in 71 of 74 (96%) and NBPB was positive in 66 of 69 (96%). In gingival-only MMP, biopsies from reflected alveolar mucosa in 17 consecutive patients were positive in 17 of 17 cases (100%). For PV, PLB was positive in 42 of 43 (98%), compared with 42 of 42 (100%) by NBPB. Histopathology was diagnostic in 93 of 134 (69·4%) cases of MMP and 38 of 41 (93%) cases of PV. IIF was positive in 126 of 197 (64·0%) MMP and 68 of 74 (92%) PV patient sera. CONCLUSIONS: In the largest series of combined oral DIF results in patients with MMP and PV, we have shown that NBPB is equivalent to PLB for the diagnosis of PV and multisite MMP, and is more sensitive than both histology and IIF. What's already known about this topic? The variation in sensitivity of oral biopsy sites for direct immunofluorescence (DIF) in the diagnosis of oral MMP and PV has not been studied in detail in large series of patients. Biopsy can be challenging due to difficult access and fragility of the oral mucosa. The diagnostic biopsy technique is therefore critical. What does this study add? We have shown that a normal buccal punch biopsy (NBPB) from uninvolved oral mucosa is as sensitive as a perilesional biopsy (PLB) for diagnosis of oral PV, and superior to serology and histology. For multisite MMP, NBPB is equivalent to PLB and is more sensitive than serology and histology. The oral punch biopsy technique on uninvolved buccal mucosa tissue is a simple and safe practical method for diagnosing oral PV and MMP.

RESUMO

The detection and semiquantitative measurement of circulating human leucocyte antigen (HLA)-specific antibodies is essential for the management of patients before and after transplantation. In addition, the pretransplant cross-match to assess the reactivity of recipient HLA antibody against donor lymphocytes has long been the gold standard to prevent hyperacute rejection. Whilst both of these tests assume that recipient HLA-specific antibody is the only variable in the assessment of transplant risk, this is not the case. Transplant immunologists recognize that some HLA antigens are expressed at levels a magnitude lower than others (e.g., HLA-C, HLA-DQ), but within loci, and between different cell types there are many factors that influence HLA expression in both resting and activated cells. HLA is not usually expressed without the specific promoter proteins NLRC5, for HLA class I, and CIITA, for class II. The quantity of HLA protein production is then affected by factors including promoter region polymorphisms, alternative exon splice sites, methylation and microRNA-directed degradation. Different loci are influenced by multiple combinations of these control mechanisms making prediction of HLA regulation difficult, but an ability to measure the cellular expression of each HLA antigen, in conjunction with knowledge of circulating HLA-specific antibody, would lead to a more informed algorithm to assess transplant risk.

RESUMO

The autoimmune blistering disorders present with variable frequency in the oral cavity. Recognition of their key clinical features at presentation is important, as there are many causes of oral ulceration. Careful history-taking, clinical examination, an understanding of pathogenesis and appropriate investigations are essential. With the exception of the rare genodermatoses that may lead to blistering and oral ulceration, the majority of patients have an acquired disorder. These include the rare autoimmune blistering diseases mucous membrane pemphigoid (MMP), pemphigus vulgaris (PV), linear IgA disease, epidermolysis bullosa acquisita and paraneoplastic pemphigus. Important clinical differential diagnoses include erythema multiforme, which may be mistaken for PV in appearance, while oral lichen planus may be indistinguishable from MMP. Angina bullosa haemorrhagica may also present with tense haemorrhagic bullae, and in the absence of diagnostic tests, requires an astute clinical diagnosis based upon the history. Newer laboratory techniques have facilitated identification of target antigens and epitopes in the autoimmune blistering diseases, particularly in MMP. Current interest is in whether these relate to clinical presentation and outcomes. There have also been recent investigations into the use of saliva as an alternative medium to serum for the diagnosis of oral vesiculobullous lesions. Assessment of disease severity and measurement of quality of life at presentation and subsequent follow-up is paramount to interpreting therapeutic response. Furthermore, combining these scores with serological and/or salivary biomarkers is valuable in the assessment of clinical response. In this paper, we discuss MMP and its important differential diagnoses.

RESUMO

OBJECTIVES: To quantify the frequency and type of medication decisions on discharge from the hospital to hospice care. DESIGN: Retrospective cohort study. SETTING: A 544-bed academic tertiary care hospital in Portland, Oregon. PARTICIPANTS: A total of 348 adult patients (age ≥18 y) discharged to hospice care between January 1, 2010, and December 31, 2016. MEASUREMENTS: Data were collected from an electronic repository of medical record data and a manual review of patients' discharge summaries. Our outcomes of interest were the frequency and type of medication decisions documented in patients' discharge summaries. Medication decisions were categorized as continuation, continuation but with changes in dose, route of administration, and/or frequency, discontinuation, and initiation of new medications. We also collected data on the frequency of patient/family in the participation of medication-related decisions. RESULTS: Patients were prescribed a mean of 7.1 medications (standard deviation [SD] = 4.8) on discharge to hospice care. The most prevalent medications prescribed on discharge were strong opioids (82.5%), anxiolytics/sedatives (62.9%), laxatives (57.5%), antiemetics (54.3%), and nonopioid analgesics (45.4%). However, only 67.8% (213/341) of patients who were prescribed an opioid on discharge to hospice care were also prescribed a laxative. Discharging providers made a mean of 15.0 decisions (SD = 7.2) per patient of which 28.5% were to continue medications without changes, 6.7% were to continue medications with changes, 30.3% were to initiate new medications, and 34.5% were to discontinue existing medications. Patients and/or family members were involved in medication decisions during 21.6% of discharges; patients were involved in 15.2% of decisions. CONCLUSION: Patients averaged more than 15 medication decisions on discharge to hospice care. However, it was rarely documented that patients and/or their families participated in these decisions.
