Integrated lymphoedema and tissue viability service: improving patient and wound outcomes.

This article will focus on the integration of tissue viability and lymphoedema services to improve outcomes for patients with leg ulceration. It will highlight why there is a need for lymphoedema specialist knowledge within the care of patients with leg ulceration and how the services are closely aligned. Lymphoedema can adversely affect wound healing and the article will provide case studies that highlight how developing a hybrid tissue viability and lymphoedema clinician or integration of the specialists can provide effective patient-centred care at reduced cost. The article offers potential strategies and suggestions on how to address inequalities in care and how to improve service provision.

Understanding family-centered care in the NICU: a scoping review protocol.

OBJECTIVE: This scoping review aims to identify and categorize the definitions of neonatal intensive care unit (NICU) family-centered care (FCC) and its associated concepts. It also aims to identify and categorize the practices and interventions that comprise NICU FCC, and catalog the metrics used to evaluate NICU FCC. INTRODUCTION: FCC has been identified as an important element of care for neonates and infants admitted to the NICU, and there is clear evidence that the incorporation of families in care improves clinical outcomes. However, FCC has been linked to numerous associated terms and concepts and lacks a unifying definition or framework, thus limiting the ability to categorize, prioritize, and identify practices and interventions to optimize both institutional approaches for individual centers and for the field at large. INCLUSION CRITERIA: Studies that include or apply at least one FCC concept or its associated terms will be considered eligible for inclusion. Studies not related exclusively to the NICU will be excluded. METHODS: The review will follow the JBI methodology for scoping reviews and will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Several electronic databases and sources of gray literature will be searched from 1992 to the present day. The review will include only full-text studies in English and will be independently screened by a minimum of 2 authors. Data will be extracted using a modified JBI data extraction tool and presented using narrative summaries; concept mapping; and categorization of practices, interventions, and metrics.

Incidence, clinical features, management and outcomes of ANCA-associated vasculitis in pregnancy- a systematic literature review.

BACKGROUND AND AIM: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are rare multi-system conditions, usually presenting in older age groups. However, younger individuals are also affected. The average increase of childbearing age and lack of studies in pregnancy necessitates this comprehensive review of data to guide the management of AAV in pregnancy. This systematic review (SR) aimed to summarise the incidence, clinical features, management and maternal and foetal outcomes in female patients with AAV. METHODS: The protocol was registered on PROSPERO (CRD42023437482). Articles published in Medline, Embase and Cochrane Databases from 1946 until June 2023 were included. Single case reports, reviews and conference abstracts were excluded. Articles meeting inclusion criteria were examined by two authors. Data on demographics, treatment, clinical features, flares during pregnancy and maternal and foetal outcomes were extracted. RESULTS: Eight studies were included, detailing 82 pregnancies in 64 women. The most common drugs used for remission induction pre-conception were cyclophosphamide, rituximab, prednisolone and azathioprine. Serious maternal complications in pregnancy included progressive tracheal/subglottic stenosis (n=5), renal disease (n=2), preeclampsia (n=10) and miscarriages (n=5). Foetal anomalies were rare (n=5). The mean birth weight was 3.37kgs and mean gestation age was 38.26 weeks. No maternal deaths or vasculitis in newborns were reported.  Conclusions: Patients can have positive maternal and foetal outcomes following strong induction therapy, vigorous monitoring and prompt treatment of flares during pregnancy. Serious complications and flares are not associated with worse outcomes for newborns.

Biallelic variants in TUBGCP6 result in microcephaly and chorioretinopathy 1: Report of four cases and a literature review.

Autosomal recessive microcephaly and chorioretinopathy-1 (MCCRP1) is a rare Mendelian disorder resulting from biallelic loss of function variants in Tubulin-Gamma Complex Associated Protein 6 (TUBGCP6, MIM#610053). Clinical features of this disorder include microcephaly, cognitive impairment, dysmorphic features, and variable ophthalmological anomalies including chorioretinopathy. Microcephaly can be recognized prenatally and visual impairment becomes evident during the first year of life. The clinical presentation resembles the findings in some acquired conditions such as congenital toxoplasmosis and cytomegalovirus infections; thus, it is important to recognize and diagnose this syndrome in view of its impact on patient health management and familial reproductive plans. To date, only seven molecularly confirmed patients from five unrelated families have been reported. We report an additional four unrelated patients with TUBGCP6 variants including one prenatal diagnosis and review the clinical phenotypes and genotypes of all the known cases. This report expands the molecular and phenotypic spectrum of TUBGCP6 and includes additional prenatal findings associated with MCCRP1.

Impact of reduced antibiotic treatment duration on antimicrobial resistance in critically ill patients in the randomized controlled SAPS-trial.

Background: In the previously reported SAPS trial (https://clinicaltrials.gov/ct2/show/NCT01139489), procalcitonin-guidance safely reduced the duration of antibiotic treatment in critically ill patients. We assessed the impact of shorter antibiotic treatment on antimicrobial resistance development in SAPS patients. Materials and methods: Cultures were assessed for the presence of multi-drug resistant (MDR) or highly resistant organisms (HRMO) and compared between PCT-guided and control patients. Baseline isolates from 30 days before to 5 days after randomization were compared with those from 5 to 30 days post-randomization. The primary endpoint was the incidence of new MDR/HRMO positive patients. Results: In total, 8,113 cultures with 96,515 antibiotic test results were evaluated for 439 and 482 patients randomized to the PCT and control groups, respectively. Disease severity at admission was similar for both groups. Median (IQR) durations of the first course of antibiotics were 6 days (4-10) and 7 days (5-11), respectively (p = 0.0001). Antibiotic-free days were 7 days (IQR 0-14) and 6 days (0-13; p = 0.05). Of all isolates assessed, 13% were MDR/HRMO positive and at baseline 186 (20%) patients were MDR/HMRO-positive. The incidence of new MDR/HRMO was 39 (8.9%) and 45 (9.3%) in PCT and control patients, respectively (p = 0.82). The time courses for MDR/HRMO development were also similar for both groups (p = 0.33). Conclusions: In the 921 randomized patients studied, the small but statistically significant reduction in antibiotic treatment in the PCT-group did not translate into a detectable change in antimicrobial resistance. Studies with larger differences in antibiotic treatment duration, larger study populations or populations with higher MDR/HRMO incidences might detect such differences.

Stakeholder identified research priorities for early intervention in psychosis.

BACKGROUND: Public resources to answer pertinent research questions about the impact of illness and treatment on people with mental health problems are limited. To target funds effectively and efficiently and maximize the health benefits to populations, prioritizing research areas is needed. Research agendas are generally driven by researcher and funder priorities, however, there is growing recognition of the need to include user-defined research priorities to make research more relevant, needs-based and efficient. OBJECTIVE: To gain consensus on top priorities for research into early intervention in psychosis through a robust, democratic process for prioritization enlisting the views of key stakeholders including users, carers and healthcare professionals. We also sought to determine which user-prioritized questions were supported by scientific evidence. DESIGN AND METHODS: We used a modified nominal group technique to gain consensus on unanswered questions that were obtained by survey and ranked at successive stages by a steering group comprising users, carer representatives and clinicians from relevant disciplines and stakeholder bodies. We checked each question posed in the survey was unanswered in research by reviewing evidence in five databases (Medline, Cinahl, PsychInfo, EMBASE and Cochrane Database). RESULTS: Two hundred and eighty-three questions were submitted by 207 people. After checking for relevance, reframing and examining for duplicates, 258 questions remained. We gained consensus on 10 priority questions; these largely represented themes around access and engagement, information needs before and after treatment acceptance, and the influence of service-user (SU) priorities and beliefs on treatment choices and effectiveness. A recovery SUtheme identified specific self-management questions and more globally, a need to fully identify factors that impact recovery. DISCUSSION AND CONCLUSIONS: Published research findings indicated that the priorities of service users, carers and healthcare professionals were aligned with researchers' and funders' priorities in some areas and misaligned in others providing vital opportunities to develop research agendas that more closely reflect users' needs. PATIENT AND PUBLIC CONTRIBUTION: Initial results were presented at stakeholder workshops which included service-users, carers, health professionals and researchers during a consensus workshop to prioritize research questions and allow the opportunity for feedback. Patient and public representatives formed part of the steering group and were consulted regularly during the research process.

Epigenetics in drug disposition & drug therapy: symposium report of the 24th North American meeting of the International Society for the Study of Xenobiotics (ISSX).

The 24th North American International Society for the Study of Xenobiotics (ISSX) meeting, held virtually from September 13 to 17, 2021, embraced the theme of "Broadening Our Horizons." This reinforces a key mission of ISSX: striving to share innovative science related to drug discovery and development. Session speakers and the ISSX New Investigators Group, which supports the scientific and professional development of student and early career ISSX members, elected to highlight the scientific content presented during the captivating session titled, "Epigenetics in Drug Disposition & Drug Therapy." The impact genetic variation has on drug response is well established; however, this session underscored the importance of investigating the role of epigenetics in drug disposition and drug discovery. Session speakers, Drs. Ning, McClay, and Lazarus, detailed mechanisms by which epigenetic players including long non-coding RNA (lncRNAs), microRNA (miRNAs), DNA methylation, and histone acetylation can alter the expression of genes involved in pharmacokinetics, pharmacodynamics, and toxicity. Dr. Ning detailed current knowledge about miRNAs and lncRNAs and the mechanisms by which they can affect the expression of drug metabolizing enzymes (DMEs) and nuclear receptors. Dr. Lazarus discussed the potential role of miRNAs on UDP-glucuronosyltransferase (UGT) expression and activity. Dr. McClay provided evidence that aging alters methylation and acetylation of DMEs in the liver, affecting gene expression and activity. These topics, compiled by the symposium organizers, presenters, and the ISSX New Investigators Group, are herein discussed, along with exciting future perspectives for epigenetics in drug disposition and drug discovery research.

Ill Fates and Heroic Feats: A Thematic Analysis of Elite Athleticism and Chronic Illness.

Far more than an individual endeavor, work is a collective enterprise, an ethic, in which individuals participate to fulfill needs of their surrounding social world. Specifically, sport professionals undergo strenuous physical labor to compete and garner public admiration. Yet, when chronic illness interferes with their performances, how are athletes expected to respond? Through a thematic analysis of newspaper discourses covering professional golfer Tim Simpson's mysterious illness over time, this study explores an athlete's persistence to compete despite his deteriorating health. Using a grounded theory approach, this study investigates the tensions between Simpson's efforts to maintain a "sport ethic" while instantaneously adhering to responsibilities expected of "healthy citizens". The analysis reveals Simpson's body as paradoxically the primary means for his athletic performance and the primary source of his declining health. Public discourses manage this paradox by diffusing disruptions provoked by Simpson's sudden illness and standardizing deviations observed of his actions to justify his work ethic. Drawing from these observations, the concluding discussion interrogates issues that surface when good health is framed as an achievement of rather than a basis for productive living.

In-vitro characterization of coding variants with predicted functional implications in the efflux transporter multidrug resistance protein 4 (MRP4, ABCC4).

MRP4 (gene ABCC4) is a polymorphic efflux transporter that has been implicated in drug-induced toxicity. We selected ten commonly observed MRP4 coding variants among Europeans for experimental characterization including nine variants predicted to be deleterious or functional (combined annotation-dependent depletion score >15). We assessed protein localization and activity by quantifying intracellular accumulation of two prototypic substrates, taurocholic acid (TCA) and estradiol 17-ß-glucuronide (E217ßG), in HEK293T over-expressing MRP4 wildtype or variant where cellular substrate loading was optimized through co-transfection with an uptake transporter. V458M, a novel variant not previously studied, and T1142M, showed reduced activity compared to MRP4 wildtype for E217ßG and TCA (P < 0.01), while L18I, G187W, K293E, and R531Q moderately increased activity in a substrate-dependent manner. Protein expression analysis indicated reduced cell surface expression for V458M (P < 0.01) but not T1142M compared to wildtype. Reduced activity may result from altered surface expression (V458M) or intrinsic activity as both variants map within the nucleotide-binding domains of MRP4. G187W showed a trend for reduced surface expression (P = 0.054) despite transport comparable or increased to wildtype suggesting enhanced intrinsic activity. Our findings suggest moderately altered MRP4 activity in six out of nine predicted functional variants with likely different mechanisms and substrate-specific effects. Cell-based studies using multiple known substrates are warranted to more accurately predict functional variants in this clinically important transporter.

Towards a Post-Graduate Level Curriculum for Biodiversity Informatics. Perspectives from the Global Biodiversity Information Facility (GBIF) Community.

Biodiversity informatics is a new and evolving field, requiring efforts to develop capacity and a curriculum for this field of science. The main objective was to summarise the level of activity and the efforts towards developing biodiversity informatics curricula, for work-based training and/or academic teaching at universities, taking place within the Global Biodiversity Information Facility (GBIF) countries and its associated network. A survey approach was used to identify existing capacities and resources within the network. Most of GBIF Nodes survey respondents (80%) are engaged in onsite training activities, with a focus on work-based professionals, mostly researchers, policy-makers and students. Training topics include data mobilisation, digitisation, management, publishing, analysis and use, to enable the accessibility of analogue and digital biological data that currently reside as scattered datasets. An initial assessment of academic teaching activities highlighted that countries in most regions, to varying degrees, were already engaged in the conceptualisation, development and/or implementation of formal academic programmes in biodiversity informatics, including programmes in Benin, Colombia, Costa Rica, Finland, France, India, Norway, South Africa, Sweden, Taiwan and Togo. Digital e-learning platforms were an important tool to help build capacity in many countries. In terms of the potential in the Nodes network, 60% expressed willingness to be recruited or commissioned for capacity enhancement purposes. Contributions and activities of various country nodes across the network have been highlighted and a working curriculum framework has been defined.

Recent developments in in vitro and in vivo models for improved translation of preclinical pharmacokinetics and pharmacodynamics data.

Improved pharmacokinetics/pharmacodynamics (PK/PD) prediction in the early stages of drug development is essential to inform lead optimization strategies and reduce attrition rates. Recently, there have been significant advancements in the development of new in vitro and in vivo strategies to better characterize pharmacokinetic properties and efficacy of drug leads. Herein, we review advances in experimental and mathematical models for clearance predictions, advancements in developing novel tools to capture slowly metabolized drugs, in vivo model developments to capture human etiology for supporting drug development, limitations and gaps in these efforts, and a perspective on the future in the field.

Pharmacogenomics in the era of next generation sequencing - from byte to bedside.

Pharmacogenetic research has resulted in the identification of a multitude of genetic variants that impact drug response or toxicity. These polymorphisms are mostly common and have been included as actionable information in the labels of numerous drugs. In addition to common variants, recent advances in Next Generation Sequencing (NGS) technologies have resulted in the identification of a plethora of rare and population-specific pharmacogenetic variations with unclear functional consequences that are not accessible by conventional forward genetics strategies. In this review, we discuss how comprehensive sequencing information can be translated into personalized pharmacogenomic advice in the age of NGS. Specifically, we provide an update of the functional impacts of rare pharmacogenetic variability and how this information can be leveraged to improve pharmacogenetic guidance. Furthermore, we critically discuss the current status of implementation of pharmacogenetic testing across drug development and layers of care. We identify major gaps and provide perspectives on how these can be minimized to optimize the utilization of NGS data for personalized clinical decision-support.

Uptake and impact of journaling program on wellbeing of NICU parents.

OBJECTIVE: This pilot study evaluated a brief parent journaling program in the neonatal intensive care unit (NICU). STUDY DESIGN: Hundred NICU parents were randomized to a control group (no journal) or an intervention group (journal provided). Parents reported pre- and post-intervention anxiety and depression symptoms using the hospital anxiety and depression scale (HADS) and qualitative journal use data. The analysis included Student's paired two-tailed t-test and two-way ANOVA. This study was registered with clinicaltrials.gov on April 1, 2020, NCT04331925. RESULT: At baseline, clinically significant anxiety was more prevalent than depression (66% vs. 23%). Post-intervention scores were best predicted by baseline scores. Relative to controls, intervention group parents experienced a decrease in anxiety from baseline (t = -1.983, p = 0.056). The same effect was not seen for depression. Most intervention group parents used the journal and provided positive feedback. CONCLUSION: Journal use rates and positive feedback support the acceptability of a NICU journaling program.

Isolated bilateral congenital lacrimal gland agenesis-a case series.

We report 2 pediatric cases of isolated bilateral congenital lacrimal gland agenesis (CLGA). Patient 1 (1 year of age) and patient 2 (2 years of age) presented with symptoms of alacrimia and were diagnosed with bilateral isolated CLGA based on magnetic resonance imaging. Both patients were otherwise healthy, with no systemic associations. Molecular analysis for genetic causes of CLGA were negative. Both have been successfully medically managed.

A Clinical Program for Transgender and Gender-Diverse Neurodiverse/Autistic Adolescents Developed through Community-Based Participatory Design.

Objective: A series of studies report elevated rates of autism and autistic characteristics among gender-diverse youth seeking gender services. Although youth with the co-occurrence present with complex care needs, existing studies have focused on co-occurrence rates. Further, clinical commentaries have emphasized provider-centered interpretations of clinical needs rather than key stakeholder-driven clinical approaches. This study aimed to employ community-based participatory research methodologies to develop a key stakeholder-driven clinical group program.Method: Autistic/neurodiverse gender-diverse (A/ND-GD) youth (N = 31), parents of A/ND-GD youth (N = 46), A/ND-GD self-advocates (N = 10), and expert clinical providers (N = 10) participated in a multi-stage community-based participatory procedure. Needs assessment data were collected repeatedly over time from A/ND-GD youth and their parents as the youth interacted with one another through ongoing clinical groups, the curriculum of which was developed progressively through the iterative needs assessments.Results: Separate adolescent and parent needs assessments revealed key priorities for youth (e.g., the importance of connecting with other A/ND-GD youth and the benefit of experiencing a range of gender-diverse role models to make gender exploration and/or gender affirmation more concrete) and parents (e.g., the need for A/ND-related supports for their children as well as provision of an A/ND-friendly environment that fosters exploration of a range of gender expressions/options). Integration and translation of youth and parent priorities resulted in 11 novel clinical techniques for this population.Conclusions: With generally high acceptability ratings for each component of the group program, this study presents a community-driven clinical model to support broad care needs and preferences of A/ND-GD adolescents.

Estimation of the burden of tinea capitis among children in Africa.

Tinea capitis is a common and endemic dermatophytosis among school age children in Africa. However, the true burden of the disease is unknown in Africa. We aimed to estimate the burden of tinea capitis among children <18 years of age in Africa. A systematic review was performed using Embase, MEDLINE and the Cochrane Library of Systematic Reviews to identify articles on tinea capitis among children in Africa published between January 1990 and October 2020. The United Nation's Population data (2019) were used to identify the number of children at risk of tinea capitis in each African country. Using the pooled prevalence, the country-specific and total burden of tinea capitis was calculated. Forty studies involving a total of 229,086 children from 17/54 African countries were identified and included in the analysis. The pooled prevalence of tinea capitis was 23% (95% CI, 17%-29%) mostly caused by Trichophyton species. With a population of 600 million (46%) children, the total number of cases of tinea capitis in Africa was estimated at 138.1 (95% CI, 102.0-174.1) million cases. Over 96% (132.6 million) cases occur in sub-Saharan Africa alone. Nigeria and Ethiopia with the highest population of children contributed 16.4% (n = 98.7 million) and 8.5% (n = 52.2 million) of cases, respectively. Majority of the participants were primary school children with a mean age of 10 years. Cases are mostly diagnosed clinically. There was a large discrepancy between the clinical and mycological diagnosis. About one in every five children in Africa has tinea capitis making it one of the most common childhood conditions in the region. A precise quantification of the burden of this neglected tropical disease is required to inform clinical and public health intervention strategies.

Estimating the number of contributors to a DNA profile using decision trees.

The interpretation of DNA profiles typically starts with an assessment of the number of contributors. In the last two decades, several methods have been proposed to assist with this assessment. We describe a relatively simple method using decision trees, that is fast to run and fully transparent to a forensic analyst. We use mixtures from the publicly available PROVEDIt dataset to demonstrate the performance of the method. We show that the performance of the method crucially depends on the performance of filters for stutter and other artefacts. We compare the performance of the decision tree method with other published methods for the same dataset.

Probing Mental Health Invisibilities during a Global Pandemic.

With much attention devoted to physical health, what unseen consequences are emerging for mental health throughout the COVID-19 pandemic? The worldly disruption of COVID-19 casts rippling effects that penetrate the bodies and spirits of people experiencing this historical moment. Many of these ripples are subtle and difficult to trace. Peering into the waters muddied by COVID-19, we explore the subtle ripples, particularly the unseen mental health implications during this pandemic. In doing so, we issue questions as departure points for scholars and practitioners to consider for future research and practice in the changing landscape of our current world.

Tolerability of oral itraconazole and voriconazole for the treatment of chronic pulmonary aspergillosis: A systematic review and meta-analysis.

BACKGROUND: Chronic pulmonary aspergillosis (CPA) requires prolonged treatment with itraconazole or voriconazole. However, adverse events (AEs) are common with the use of these agents, with the need to discontinue the offending drug in a significant proportion of the patients. The aim of this study was to evaluate the frequency of adverse events of itraconazole and voriconazole for the treatment of CPA. METHODS: We searched Embase and Medline to select clinical studies providing information on AEs to itraconazole or voriconazole for the treatment of CPA from inception to May 2020. Reviews, single case reports, and case series reporting less than 10 patients were excluded. Random effect meta-analysis was performed using STATA 16.0. RESULTS: We included 9 eligible studies with an overall total of 534 CPA patients enrolled. Of these, 69% (n = 366) were treated with voriconazole and 31% (n = 168) with itraconazole. The median daily dose of both itraconazole and voriconazole used was 400mg. In a pooled analysis, AEs were observed in 36% (95% CI: 20-52%, N = 366) of patients on voriconazole and 25% (95% CI: 18 to 31%, N = 168) in those treated with itraconazole. Discontinuation rate due to AEs was the same for both drugs; 35% (47/366) and 35% (15/168) for voriconazole and itraconazole, respectively. There were 70 AEs reported with itraconazole use, the commonest being cardiotoxicity (29%). Skin AEs (28%) were the most frequent among the 204 AEs reported with voriconazole use. None of the studies compared the tolerability of itraconazole head-to-head with voriconazole. CONCLUSIONS: AEs due itraconazole and voriconazole are common and may lead to discontinuation of treatment in a significant proportion of patients. This information can be used to educate patients prior to commencement of these antifungal therapies. PROSPERO REGISTRATION NUMBER: CRD42020191627.
