RESUMO
AIM: To analyse the literature on parents' experiences of accessing mental health services with their adolescents for mental health challenges in Ireland. BACKGROUND: Health systems globally have inadequately addressed mental health service needs resulting in notable gaps between population needs and access to adolescent mental health services. METHODS: This scoping review followed Arksey and O'Malley's six-stage framework and PRISMA-ScR reporting guidelines. Five electronic databases SocINDEX, MEDLINE, CINHAL, Scopus and EBSCO were searched and reference lists screened 2015-2024. RESULTS: Twenty-three studies were included. Applying Braun and Clarke's thematic analysis identified three themes: adolescent community mental health services for adolescents with mental health challenges, accessing mental healthcare services via emergeny departments for adolescents with mental health challenges and parents' experiences of accessing mental health services for their adolescents with mental health challenges. CONCLUSION: Parents' experiences of accessing mental health services for their adolescents are not fully understood, and further research is required to map key concepts to inform practice and policymaking. RELEVANCE TO CLINICAL PRACTICE: The findings from this scoping review highlight challenges for adolescent mental health services in Ireland and internationally. Heightening awareness of these issues is necessary to improve the clinical practice of nurses. NO PATIENT OR PUBLIC CONTRIBUTION: This was a scoping review study.
RESUMO
AIM: To explore the components of personal passports for people living with dementia in an acute healthcare setting. BACKGROUND: Globally, supporting people with dementia poses a prominent health and social care challenge. Importance for people with dementia in an acute healthcare setting includes social relationships and communication with healthcare staff. A personal passport is an international initiative designed to support the personhood of the person living with dementia. METHODS: This integrative review is based on the methodology of Whittmore and Knafl (2005). The Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist were adhered to. A database search of PubMed, MEDLINE, CINAHL, Scopus and EBSCO databases was systematically performed. RESULTS: This integrative review identified nine research studies on the components of personal passports that met the inclusion and exclusion criteria. A constant comparative method of data analysis identified five key pivotal themes: person-centredness, communication, family/carer involvement, education and leadership. CONCLUSION: The use of personal passports supports the provision of person-centred care for people living with dementia through enhancing the well-being of both the person and their families/caregivers. RELEVANCE TO CLINICAL PRACTICE: Personal passports are an important document and should be determined by the person with dementia, their care needs and the caregiver's role in meeting these needs.

AIMS: To explore Advanced Nurse Practitioners' (ANP) (Emergency) perceptions of their role, positionality and professional identity. BACKGROUND: Advanced nursing practice was formally established in the Republic of Ireland in 2001 with 336 ANPs currently registered, projection increasing to a critical mass of 750 by 2021. Advanced practitioners (Emergency) give full emergency care for a specific cohort of clients with unscheduled, undifferentiated and undiagnosed conditions. DESIGN: Qualitative narrative inquiry using Bourdieu's concepts of habitus, field and capital as the theoretical framework was undertaken. METHODS: Data were collected in 10 in-depth interviews and thematic analysis applied. RESULTS: Five key themes emerged: participants' career pathways, personal and professional transitions, role dimensions and core concepts, and position in the organization and emergent professional identity. Role transitioning and a change in habitus, field and capital revealed the uniqueness of their nursing role. Minimizing waiting times, timely patient care and patient satisfaction were key performance indicators. A heightened awareness regarding higher-level decision-making, autonomy and accountability is integral to advanced practice. CONCLUSION: This study presents unique insights into the ANP role covering recruitment, organizational culture changes required and support to ease transition emerged. IMPACT: Better understanding the motivation to undertake the role, the transition experience and use of advanced practice skills sets will inform the targets for the future recruitment and retention of ANPs are met nationally and internationally. Dissatisfaction with previous management roles and wanting to be clinically close to patients were motivations to follow an advanced practice clinical career trajectory. Positionality and emergent professional identity are key enablers ensuring that advanced practitioners' roles demonstrate the attributes of advanced practice. Educators could use the findings to develop recruitment, retention and progression strategies. Disseminating the role and scopes of practice could positively influence collaborative models of service delivery and policy development.

The advanced nurse practitioner (ANP) role was established in Ireland in 2001 and represents an important nursing role development within Irish healthcare. Currently there are 336 ANPs registered with the Nursing and Midwifery Board of Ireland, working across 40 specialties. This number is increasing exponentially in response to emerging and anticipated future service needs and population demand projecting to a critical mass of 750 by 2021. Health service provision is enhanced by advanced practice performance outcomes. This article explores nurse to advanced nurse practitioner transitional journeys, a concept that has not previously been researched in depth from an Irish perspective. The theories of Benner, Woods, and Bourdieu are reviewed to explore whether an advance practice career trajectory results in unique nurse-to-ANP role transitioning. Contextualising possible personal, professional and educational transitions may enable the promotion of effective career 'scaffolding' to enhance a smooth transition for aspiring ANPs into advanced nursing practice roles.

BACKGROUND: Patients who have had inadequate response to tumour necrosis factor inhibitors have fewer treatment options and are generally more treatment refractory to subsequent therapeutic interventions than previously untreated patients. We report the efficacy and safety of ixekizumab, a monoclonal antibody that selectively targets interleukin-17A, in patients with active psoriatic arthritis and previous inadequate response to tumour necrosis factor inhibitors. METHODS: In this double-blind, multicentre, randomised, placebo-controlled, phase 3 study (SPIRIT-P2), patients were recruited from 109 centres across ten countries in Asia, Australia, Europe, and North America. Patients were aged 18 years or older, had a confirmed diagnosis of psoriatic arthritis for at least 6 months, and had a previous inadequate response, distinguished by being refractory to therapy or had loss of efficacy, or were intolerant to tumour necrosis factor inhibitors. Patients were randomly assigned (1:1:1) by a computer-generated random sequence to receive a subcutaneous injection of 80 mg ixekizumab every 4 weeks or every 2 weeks after a 160 mg starting dose or placebo. The primary endpoint was the proportion of patients who attained at least 20% improvement in the American College of Rheumatology response criteria (ACR-20) at week 24. This study is registered with ClinicalTrials.gov, number NCT02349295. FINDINGS: Between March 3, 2015, to March 22, 2016, 363 patients were randomly assigned to placebo (n=118), ixekizumab every 4 weeks (n=122), or ixekizumab every 2 weeks (n=123). At week 24, a higher proportion of patients attained ACR-20 with ixekizumab every 4 weeks (65 [53%] patients; effect size vs placebo 33·8% [95% CI 22·4-45·2]; p<0·0001) and ixekizumab every 2 weeks (59 [48%] patients; 28.5% [17·1-39.8]; p<0·0001) than did patients with placebo (23 [20%] patients). Up to week 24, serious adverse events were reported in three (3%) patients with ixekizumab every 4 weeks, eight (7%) with ixekizumab every 2 weeks, and four (3%) with placebo; no deaths were reported. Infections were reported in 47 (39%) patients with ixekizumab every 4 weeks, 47 (38%) with ixekizumab every 2 weeks, and 35 (30%) with placebo. Three (2%) serious infections, all in patients in the ixekizumab every 2 weeks group, were reported. INTERPRETATION: Both the 2-week and 4-week ixekizumab dosing regimens improved the signs and symptoms of patients with active psoriatic arthritis and who had previously inadequate response to tumour necrosis factor inhibitors, with a safety profile consistent with previous studies investigating ixekizumab. FUNDING: Eli Lilly and Company.

Objectives: To assess the long-term safety and efficacy of ixekizumab, an IL-17A antagonist, in patients with active PsA. Methods: In SPIRIT-P2 (NCT02349295), patients (n = 363) with previous inadequate response to TNF inhibitors entered the double-blind period (weeks 0-24) and received placebo or ixekizumab 80 mg every 4 weeks (IXEQ4W) or every 2 weeks (IXEQ2W) following a 160-mg starting dose at week 0. During the extension period (weeks 24-156), patients maintained their original ixekizumab dose, and placebo patients received IXEQ4W or IXEQ2W (1:1). We present the accumulated safety findings (week 24 up to 156) at the time of this analysis for patients who entered the extension period (n = 310). Exposure-adjusted incidence rates (IRs) per 100 patient years are presented. ACR responses are presented on an intent-to-treat basis using non-responder imputation up to week 52. Results: From week 24 up to 156 (with 228 patient years of ixekizumab exposure), 140 [61.3 IR] and 15 (6.6 IR) patients reported infections and serious adverse events, respectively. Serious adverse events included one death and four serious infections. In all patients initially treated with IXEQ4W and IXEQ2W at week 0 (non-responder imputation), ACR20 (61 and 51%), ACR50 (42 and 33%) and ACR70 (26 and 18%) responses persisted out to week 52. Placebo patients re-randomized to ixekizumab demonstrated efficacy as measured by ACR responses at week 52. Conclusion: During the extension period, the overall safety profile of ixekizumab remained consistent with that observed with the double-blind period, and clinical improvements persisted up to 1 year.

Objectives: A high-dose 12 mg/kg/day (6 mg/kg twice daily) voriconazole regimen was recommended by the CDC to treat patients injected with contaminated methylprednisolone acetate that caused a multi-state fungal outbreak in 2012-13. Therapeutic drug monitoring results of this unique regimen are unknown, as is the most appropriate dosing weight for obese patients. We evaluated voriconazole trough measurements for this dosing scheme, as well as the use of adjusted body weight dosing for obese patients. Methods: Voriconazole trough levels were analysed in obese (BMI ≥35 kg/m 2 ) and non-obese (BMI <35 kg/m 2 ) patients who were given initial therapy with 12 mg/kg/day. Results: Of 138 patients, the first steady-state voriconazole troughs were supratherapeutic (>5 mg/L) in 65 (47%) patients, therapeutic (2-5 mg/L) in 57 (41%) patients and subtherapeutic (<2 mg/L) in 16 (12%) patients. Twenty-three patients had pre-steady-state dose decreases due to supratherapeutic levels, with subsequent first steady-state troughs in the therapeutic ( n = 17) and subtherapeutic ( n = 6) categories. Voriconazole doses >11 and >8 mg/kg/day produced mainly first steady-state supratherapeutic troughs in 44 obese and 94 non-obese patients, respectively. An initial 12 mg/kg/day was progressively lowered to a median maintenance dose of 8.5 mg/kg/day in the obese and 8.6 mg/kg/day in the non-obese. Conclusions: A high-dose voriconazole regimen produced initial supratherapeutic troughs that required dose adjustment downward by nearly 30%. Adjusted body weight dosing in obese patients resulted in a similar maintenance dose to total body weight dosing in the non-obese, and appears to be a sensible dosing strategy for these patients.

Voriconazole is an important agent in the antifungal armamentarium. It is the treatment of choice for invasive aspergillosis, other hyaline molds, and many brown-black molds. It is also effective for infections caused by Candida species, including those that are fluconazole resistant, and for infections caused by the endemic mycoses, including those that occur in the central nervous system. It has the advantage of being available in both an intravenous and an oral formulation that is well absorbed. Drawbacks to the use of voriconazole are that it has unpredictable, nonlinear pharmacokinetics with extensive interpatient and intrapatient variation in serum levels. Some of the adverse effects seen with voriconazole are related to high serum concentrations, and, as a result, therapeutic drug monitoring is essential when using this agent. Drug-drug interactions are common, and possible interactions must be sought before voriconazole is prescribed. With prolonged use, newly described adverse effects, including periostitis, alopecia, and development of skin cancers, have been noted.

BACKGROUND: Voriconazole was 1 of 2 antifungal agents recommended for treatment of fungal infections associated with injection of contaminated methylprednisolone. Alopecia and nail changes are not commonly reported side effects of voriconazole. Having noted increasing hair loss among our patients treated with voriconazole, we sought to determine the prevalence and characteristics of alopecia associated with this agent. METHODS: Patients who received voriconazole for at least 1 month for probable or confirmed fungal infection were eligible to complete a survey regarding alopecia and nail changes. For those patients who reported alopecia, additional questions about reversal of hair loss were asked after voriconazole had been stopped for at least 3 months. RESULTS: A total of 152 of 175 eligible patients (87%) completed the survey. One hundred twenty-five (82%) reported alopecia. Hair loss on the scalp was noted in 120 (96%), arms and legs in 52 (42%), and eyebrows and eyelashes in 47 each (38%). Nineteen patients (15%) reported wearing a wig or hat because of extensive hair loss. Alopecia developed a mean (standard deviation) of 75 (54) days after initiation of voriconazole. Of 114 patients who were off voriconazole for at least 3 months, hair loss had stopped in 94 (82%) and regrowth had begun in 79 (69%), including those who were changed to either itraconazole or posaconazole. Nail changes or loss occurred in 106 (70%) patients. CONCLUSIONS: Alopecia and nail changes were common adverse effects associated with voriconazole therapy during the multistate fungal outbreak.

BACKGROUND: Voriconazole is a triazole antifungal medication used for prophylaxis or to treat invasive fungal infections. Inflammation of the periosteum resulting in skeletal pain, known as periostitis, is a reported side effect of long-term voriconazole therapy. The trifluorinated molecular structure of voriconazole suggests a possible link between excess fluoride and periostitis, as elevated blood fluoride has been reported among patients with periostitis who received voriconazole. METHODS: Two hundred sixty-four patients from Michigan were impacted by the multistate outbreak of fungal infections as a result of contaminated methylprednisolone injections. A retrospective study was conducted among 195 patients who received voriconazole therapy at St Joseph Mercy Hospital during this outbreak. Twenty-eight patients who received both bone scan and plasma fluoride measurements for skeletal pain were included in the statistical analyses. Increased tracer uptake on bone scan was considered positive for periostitis. The primary outcome measure was the correlation between plasma fluoride and bone scan results. RESULTS: Blood fluoride (P < .001), alkaline phosphatase (P = .020), daily voriconazole dose (P < .001), and cumulative voriconazole dose (P = .027) were significantly elevated in patients who had periostitis compared with those who did not. Discontinuation or dose reduction of voriconazole resulted in improvement of pain in 89% of patients. CONCLUSIONS: High plasma fluoride levels coupled with skeletal pain among patients who are on long-term voriconazole therapy is highly suggestive of periostitis. Initial measurement of fluoride may be considered when bone scan is not readily available. Early detection should be sought, as discontinuation of voriconazole is effective at reversing the disease.

BACKGROUND: Students often enter graduate healthcare/biomedical schools with insufficient undergraduate instruction in effective writing, yet the ability to write well affects their career opportunities in health care and in scientific research. PURPOSE: The present study was conducted to determine the value and effectiveness of instruction by faculty with expertise in teaching writing at a writing center at an academic health science center. METHODS: Two separate sources of data were collected and analyzed. First, an anonymous campus-wide survey assessed students' satisfaction and utilization of the university's Writing Center. Second, a nonexperimental objective study was conducted comparing a subsample of students who used versus those who did not receive instruction at the Writing Center on quality of writing, as determined by an evaluator who was blind to students' utilization status. RESULTS: From the campus-wide survey, more than 90% of respondents who used the center (which was 26% of the student body) agreed that it was a valuable and effective resource. From the objective study of writing quality, students who used the Writing Center were twice as likely as students who did not to receive an A grade on the written assignment, and the blinded evaluator accurately estimated which students used the Writing Center based on the clarity of writing. CONCLUSIONS: The instruction at the Writing Center at our university is highly valued by students, and its value is further supported by objective evidence of efficacy. Such a center offers the opportunity to provide instruction that medical and other healthcare students increasingly need without requiring additions to existing curricula. By developing competency in writing, students prepare for scholarly pursuits, and through the process of writing, they engage critical thinking skills that can make them more attuned to narrative and more reflective and empathetic in the clinical setting.

Changing environmental temperatures impact the physiological performance of fishes, and consequently their distributions. A mechanistic understanding of the linkages between experienced temperature and the physiological response expressed within complex natural environments is often lacking, hampering efforts to project impacts especially when future conditions exceed previous experience. In this study, we use natural chemical tracers to determine the individual experienced temperatures and expressed field metabolic rates of Atlantic bluefin tuna (Thunnus thynnus) during their first year of life. Our findings reveal that the tuna exhibit a preference for temperatures 2-4 °C lower than those that maximise field metabolic rates, thereby avoiding temperatures warm enough to limit metabolic performance. Based on current IPCC projections, our results indicate that historically-important spawning and nursery grounds for bluefin tuna will become thermally limiting due to warming within the next 50 years. However, limiting global warming to below 2 °C would preserve habitat conditions in the Mediterranean Sea for this species. Our approach, which is based on field observations, provides predictions of animal performance and behaviour that are not constrained by laboratory conditions, and can be extended to any marine teleost species for which otoliths are available.

F Scott Fitzgerald spent the 1930s writing about illness themes while he struggled with tuberculosis, insomnia, alcoholism, heart disease and the mental illness of his wife Zelda. During this decade, Fitzgerald published six stories that prominently feature hospitals and healthcare professionals. These stories, the 'doctor-nurse stories', along with nine additional published stories that touch upon medical themes have not previously been investigated as a thematic grouping. This paper explores the 1930s stories in the context of Fitzgerald's life and career in order to highlight his significant yet previously undervalued contribution to the canon of illness literature and his work's relevance to the field of literature and medicine.

BACKGROUND: Writing is taught as professional competency in higher education generally, but the health science education literature emphasizes writing as a pedagogical means rather than a professional end. The Medical University of South Carolina established a Writing Center in 1994 to teach professional writing. SUMMARY: This report describes the rationale for profession-specific, graduate-level writing instruction; summarizes the Writing Center model; and reports usage data. Students have reported improvement in particular texts and said they would be better able to complete writing tasks in the future. CONCLUSIONS: Interventions modeled after the Writing Center and staffed with professionally trained writing teachers may provide a means to pool resources to teach writing as professional competency. The Writing Center has provided the expertise to teach professional writing without demanding curricular revision.

INTRODUCTION: Lasmiditan is a selective serotonin (5-HT1F) receptor agonist approved in the US for the acute treatment ofmigraine in adults. This phase I, open-label, two-cohort study assessed the pharmacokinetics (PK), safety, and tolerability of lasmiditan in patients with migraine aged 6 to < 18 years. METHODS: Cohort 1 (15 to ≤ 40 kg) and Cohort 2 (> 40 to ≤ 55 kg) received single oral doses of lasmiditan (100 mg and 200 mg, respectively).Blood samples for the assessment of PK and safety parameters were collected over a 24-h period. Follow-up was approximately 14 days after dosing. RESULTS: Eighteen patients received lasmiditan (11 in Cohort 1, 7 in Cohort 2) and 17 patients completed the study. One patient in Cohort 2 discontinued due to adverse events. Plasma concentrations peaked at 1.5-2 h post dose and then declined, with a terminal half-life of approximately 4 h in both cohorts. While the exposure to lasmiditan was generally similar between cohorts, PK parameters, such as apparent total body clearance and volume of distribution, were greater for the 200 mg cohort relative to the 100 mg cohort. No deaths or serious adverse events were reported. The frequency and severity of adverse events (including somnolence, dizziness, and fatigue) were generally mild and similar to those in adult studies. CONCLUSION: The PK results support weight-based dosing of lasmiditan in pediatric patients with migraine and no new safety or tolerability issues were identified. These findings support further investigation of lasmiditan as a potential treatment in pediatric patients with migraine. Clinical Trial Registration Numbers NCT03988088 and EMEA-002166-PIP01-17M02.

OBJECTIVE: To evaluate the effect of withdrawing ixekizumab in patients with psoriatic arthritis (PsA) in whom minimal disease activity (MDA) has been achieved after open-label ixekizumab treatment. METHODS: SPIRIT-P3 was a multicenter, randomized, double-blind withdrawal study of biologic treatment-naive adult patients with PsA who were treated with open-label ixekizumab for 36 weeks (160 mg at week 0, then 80 mg every 2 weeks). Patients in whom MDA was sustained for >3 consecutive months were randomized 1:1, between weeks 36 and 64, to undergo blinded withdrawal of ixekizumab treatment (placebo) or to continue ixekizumab treatment every 2 weeks up to week 104. The primary efficacy end point was time to relapse (loss of MDA) for randomized patients. Patients who experienced a relapse were re-treated with ixekizumab every 2 weeks up to week 104. RESULTS: A total of 394 patients were enrolled and received open-label ixekizumab every 2 weeks. Of those patients, 158 (40%) achieved sustained MDA and were randomized to undergo withdrawal of ixekizumab treatment (placebo every 2 weeks; n = 79) or to continue ixekizumab treatment every 2 weeks (n = 79). Disease relapse occurred more rapidly with treatment withdrawal (median 22.3 weeks [95% confidence interval (95% CI) 16.1-28.3]) compared to those who continued treatment with ixekizumab (median not estimable; P < 0.0001). Sixty-seven patients (85%) compared to 30 patients (38%) experienced relapse in the placebo group and the continued treatment group, respectively. Median time to achieving MDA again with re-treatment was 4.1 weeks (95% CI 4.1-4.3); in 64 of 67 patients (96%) who experienced relapse with treatment withdrawal, MDA was achieved again with re-treatment. Safety was consistent with the known safety profile for ixekizumab. CONCLUSION: Continued ixekizumab therapy is superior to ixekizumab withdrawal in maintaining low disease activity in biologic treatment-naive patients with PsA. Re-treatment with ixekizumab following a relapse may restore disease control in cases of treatment interruption.

Ixekizumab, a high-affinity monoclonal antibody that selectively targets IL-17A, is efficacious for moderate to severe plaque psoriasis. We examined relationships between serum ixekizumab concentrations, treatment-emergent anti-drug antibodies (TE-ADAs), and efficacy during 60 weeks of treatment in a randomized, controlled, phase 3 study. Steady-state ixekizumab serum trough concentrations were rapidly achieved and associated with high clinical responses at week 12 with a starting dose of 160 mg followed by 80 mg every 2 weeks. During the long-term extension period dosage of 80 mg every 4 weeks, stable serum trough concentrations maintained high clinical responses through week 60. Most (82.6%, 308/373) patients never developed TE-ADA. In TE-ADA-positive patients (17.4%, n = 65), variations in ADA titers, neutralizing capacity, and persistence were observed. Fifty-six patients (15%) developed low or moderate maximum titers, with serum concentrations and efficacy comparable to those of TE-ADA-negative patients. Nine patients (2.4%) developed high titers, with variable individual clinical responses; four of these nine patients achieved at least PASI 75 at week 60. Median serum concentrations in the TE-ADA-high titer group were generally comparable to the median serum concentrations in the lower titer groups. For most patients, TE-ADA had a negligible impact on ixekizumab serum concentrations and efficacy. Clinicaltrials.gov: NCT01646177.

BACKGROUND: Although psoriatic arthritis is complex and involves multiple domains, recent advances in treatments have made remission or near-remission of most symptoms a potentially achievable goal for many patients. We sought to evaluate whether achieving minimal disease activity (MDA) criteria represented meaningful improvement from the patient perspective. METHODS: Data were combined from two randomized, multinational, 24 week clinical studies of ixekizumab, a high-affinity monoclonal antibody selectively targeting interleukin-17A, in biological drug-naïve or experienced adults. MDA required 5 of 7 of: tender joint count ≤1; swollen joint count ≤1; Psoriasis Area and Severity Index total score ≤ 1 or body surface area ≤ 3%; patient's assessment of pain visual analogue scale (VAS) ≤15; patient's global assessment of disease activity VAS ≤20; Health Assessment Questionnaire Disability Index ≤0.5; and tender entheseal points ≤ 1. MDA responders and non-responders were compared for mean change from baseline on the 36-Item Short Form Health Survey (SF-36), European Quality of Life 5 Dimension 5 Level Health Questionnaire (EQ-5D-5 L); EQ-5D-5 L VAS; and Work Productivity and Activity Impairment-Specific Health Problem (WPAI-SHP) questionnaire. RESULTS: MDA responders had significantly greater improvements versus non-responders in each SF-36 domain and in the SF-36 physical summary score; improvements were also greater in the EQ-5D-5 L and EQ-5D-5 L VAS, and in 3 of the 4 WPAI-SHP domains. MDA responders were more likely to achieve minimal clinically important differences than non-responders. CONCLUSION: These findings support MDA response as being strongly associated with achieving improved disease status based on measures of patient reported health-related quality of life and productivity.
