Inclusion of the severe and enduring anorexia nervosa phenotype in genetics research: a scoping review. J Eat Disord 2024; 12:53. [PMID: 38685102 PMCID: PMC11059621 DOI: 10.1186/s40337-024-01009-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 04/23/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Anorexia nervosa has one of the highest mortality rates of all mental illnesses. For those who survive, less than 70% fully recover, with many going on to develop a more severe and enduring phenotype. Research now suggests that genetics plays a role in the development and persistence of anorexia nervosa. Inclusion of participants with more severe and enduring illness in genetics studies of anorexia nervosa is critical. OBJECTIVE The primary goal of this review was to assess the inclusion of participants meeting the criteria for the severe enduring anorexia nervosa phenotype in genetics research by (1) identifying the most widely used defining criteria for severe enduring anorexia nervosa and (2) performing a review of the genetics literature to assess the inclusion of participants meeting the identified criteria. METHODS Searches of the genetics literature from 2012 to 2023 were performed in the PubMed, PsycINFO, and Web of Science databases. Publications were selected per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The criteria used to define the severe and enduring anorexia nervosa phenotype were derived by how often they were used in the literature since 2017. The publications identified through the literature search were then assessed for inclusion of participants meeting these criteria. RESULTS most prevalent criteria used to define severe enduring anorexia nervosa in the literature were an illness duration of ≥ 7 years, lack of positive response to at least two previous evidence-based treatments, a body mass index meeting the Diagnostic and Statistical Manual of Mental Disorders-5 for extreme anorexia nervosa, and an assessment of psychological and/or behavioral severity indicating a significant impact on quality of life. There was a lack of consistent identification and inclusion of those meeting the criteria for severe enduring anorexia nervosa in the genetics literature. DISCUSSION This lack of consistent identification and inclusion of patients with severe enduring anorexia nervosa in genetics research has the potential to hamper the isolation of risk loci and the development of new, more effective treatment options for patients with anorexia nervosa.

Abstract
Abstract
Introduction
Approximately 60% of older adults complain of dry mouth which may be associated with polypharmacy, common in this population. Existing studies have reported treatment approaches to dry mouth but do not address long-term, preventative measures that would more positively benefit the health and wellbeing of older adults.1
Aim
This rapid systematic review aims to identify the implications of dry mouth on the physical and psychological wellbeing of older adults with polypharmacy to establish the importance of preventing dry mouth.
Methods
Studies reporting health implications of dry mouth, in relation to polypharmacy in older adults (>65 years old), were included in this rapid systematic review. MEDLINE, EMBASE, PsycINFO and CINAHL databases were searched using Keywords such as ‘polypharmacy’, ‘dry mouth’, ‘oral health’ and ‘quality of life’ (PROSPERO: CRD42021288945). Joanna Briggs Institute critical appraisal tools were used to assess study quality. Ethical approval was not required for this project due to the methodology of this rapid systematic review.
Results
Of the 6,852 citations screened, 9 studies (cross-sectional, n = 8; longitudinal, n = 1) were included which comprised 37,459 participants (mean age range: 68.5-85.0 years). Studies were published between 2005 and 2019. Meta-analysis was not possible due to the heterogenicity of outcomes reported; instead, a narrative synthesis was undertaken. The health implications identified in this review were categorised as ‘physical’, such as tooth loss, or ‘psychological’, such as depression. The main physical health implications reported in the studies related to dental health, such as tooth loss and gingivitis, as well as functional impairments, such as chewing and swallowing difficulties. An increase in the number of medicines taken, from 0 to 5, decreased the number of natural teeth remaining from 16.35 ±8.58 to 11.74 ±7.88, respectively. Additionally, the number of dental complications increased from 1.43 ±2.1 to 2.33 ±2.2 as the number of medicines increased from 1 to >3, respectively. There was a paucity of studies (n = 2) that investigated the psychological health implications of dry mouth upon older adult populations. Depression, was however, identified as a significant consequence of dry mouth in older adults with a prevalence as high as 64%.2 An additional 6 psychological health implications were identified, for example, self-consciousness.
Discussion/Conclusion
This review examined the health implications of dry mouth in relation to polypharmacy in older adults, including physical health and psychological health implications. There were limitations in this review; for example, the predominant cross-sectional study design restricted findings due to the inability to establish longitudinal associations. High levels of physical health implications of dry mouth were observed in older adults with polypharmacy and, to a lesser extent, psychological health implications. The modifiable nature of polypharmacy could pave the way for prevention strategies of dry mouth. The optimisation of medication regimens, to effectively treat chronic conditions but also limit the likelihood of dry mouth, is a practical approach to achieve this.3

Abstract
Ventilator-associated pneumonia is the most common healthcare-associated infection in mechanically ventilated patients. Despite this, accurate diagnosis of ventilator-associated pneumonia is difficult owing to the variety of criteria that exist. In this prospective national audit, we aim to quantify the existence of patients with suspected ventilator-associated pneumonia that would not be detected by our standard healthcare-associated infection screening process. Furthermore, we aim to assess the impact of tracheostomy insertion, subglottic drainage endotracheal tubes and chlorhexidine gel on ventilator-associated pneumonia rate. Of the 227 patients recruited, suspected ventilator-associated pneumonia occurred in 32 of these patients. Using the HELICS definition, 13/32 (40.6%) patients were diagnosed with ventilator-associated pneumonia (H-posVAP). Suspected ventilator-associated pneumonia rate was increased in our tracheostomy population, decreased in the subglottic drainage endotracheal tube group and unchanged in the chlorhexidine group. The diagnosis of ventilator-associated pneumonia remains a contentious issue. The formalisation of the HELICS criteria by the European CDC should allow standardised data collection throughout Europe, which will enable more consistent data collection and meaningful data comparison in the future. Our data add weight to the argument against routine oral chlorhexidine. The use of subglottic drainage endotracheal tubes in preventing ventilator-associated pneumonia is interesting and requires further investigation.

Abstract
Chronic wounds, including diabetic foot ulcers, pressure ulcers and venous leg ulcers, impact the lives of millions of people worldwide. These types of wounds represent a significant physical, social and financial burden to both patients and health care systems. Wound care has made great progress in recent years as a result of the critical research performed in academic, clinical and industrial settings. However, there has been relatively little translation of basic research discoveries into novel and effective treatments. One underlying reason for this paucity may be inconsistency in the methods of wound analysis and sample collection, resulting in the inability of researchers to accurately characterise the healing process and compare results from different studies. This review examines the various types of analytical methods being used in wound research today with emphasis on sampling techniques, processing and storage, and the findings call forth the wound care research community to standardise its approach to wound analysis in order to yield more robust and comparable data sets.

Ancillary study management systems: a review of needs. BMC Med Inform Decis Mak 2013; 13:5.

Abstract
BACKGROUND The valuable clinical data, specimens, and assay results collected during a primary clinical trial or observational study can enable researchers to answer additional, pressing questions with relatively small investments in new measurements. However, management of such follow-on, "ancillary" studies is complex. It requires coordinating across institutions, sites, repositories, and approval boards, as well as distributing, integrating, and analyzing diverse data types. General-purpose software systems that simplify the management of ancillary studies have not yet been explored in the research literature. METHODS We have identified requirements for ancillary study management primarily as part of our ongoing work with a number of large research consortia. These organizations include the Center for HIV/AIDS Vaccine Immunology (CHAVI), the Immune Tolerance Network (ITN), the HIV Vaccine Trials Network (HVTN), the U.S. Military HIV Research Program (MHRP), and the Network for Pancreatic Organ Donors with Diabetes (nPOD). We also consulted with researchers at a range of other disease research organizations regarding their workflows and data management strategies. Lastly, to enhance breadth, we reviewed process documents for ancillary study management from other organizations. RESULTS By exploring characteristics of ancillary studies, we identify differentiating requirements and scenarios for ancillary study management systems (ASMSs). Distinguishing characteristics of ancillary studies may include the collection of additional measurements (particularly new analyses of existing specimens); the initiation of studies by investigators unaffiliated with the original study; cross-protocol data pooling and analysis; pre-existing participant consent; and pre-existing data context and provenance. For an ASMS to address these characteristics, it would need to address both operational requirements (e.g., allocating existing specimens) and data management requirements (e.g., securely distributing and integrating primary and ancillary data). CONCLUSIONS The scenarios and requirements we describe can help guide the development of systems that make conducting ancillary studies easier, less expensive, and less error-prone. Given the relatively consistent characteristics and challenges of ancillary study management, general-purpose ASMSs are likely to be useful to a wide range of organizations. Using the requirements identified in this paper, we are currently developing an open-source, general-purpose ASMS based on LabKey Server (http://www.labkey.org) in collaboration with CHAVI, the ITN and nPOD.

Abstract
Severe sepsis is a common cause of admission to the intensive care unit and is associated with a high hospital mortality. This audit explored the current use of, and attitudes towards, recombinant activated protein C therapy across Scotland, and compared these with current guidance. Patients with severe sepsis were followed for three days. Consideration and/or usage of recombinant activated protein C were compared with two different guidelines. Ninety-seven patients were admitted to the intensive care unit over the audit period. Recombinant activated protein C was used in nine of these patients. Depending on the criteria used, between 50% and 81% of the patients who qualified for recombinant activated protein C therapy did not receive it. Subsequent to the audit, a survey was performed to study intensive care unit consultants' attitudes to recombinant activated protein C therapy. A total of 125 consultants responded to the survey (77%). Of these, 104 (83%) stated that they used recombinant activated protein C in their clinical practice, 56 (52%) of whom prescribed it to patients with two-organ failures and an Acute Physiology and Chronic Health Evaluation II score of ≥ 25. Thirty-nine respondents (38%) stated that two-organ failures alone would be an adequate trigger for therapy. We conclude that recombinant activated protein C is potentially under-used to treat severe sepsis. Many consultants seem to reserve the drug for the most severely ill sub group of patients.

Abstract
Small intestine submucosa (SIS), a bioactive extracellular matrix (ECM) containing critical components of the ECM including collagens, proteoglycans, and glycosaminoglycans, has been widely used for wound healing. The purpose of this study was to investigate the interaction between SIS and matrix metalloproteinases (MMPs). MMP-1, MMP-2, and MMP-9 displayed different binding affinities, indicated by a loss in activity in solution upon incubation with SIS at 53·8%, 85·9%, and 36·9% over 24 hours, respectively. A cell migration study was conducted to evaluate the effects of MMPs and SIS on keratinocytes. The results indicated that MMPs inhibit keratinocyte migration in vitro, and that the inhibition can be significantly reduced by pre-incubating the MMP solution with SIS. To evaluate activity in vivo a diabetic mouse wound healing study was conducted. Biopsy samples were collected on different days for analysis of MMP levels by gelatin zymography. MMP activity was found to be attenuated by SIS treatment on day 3 after wounding. On day 7, the attenuation became less significant indicating that the MMP binding ability of SIS had become saturated. SIS was able to reduce MMP activity immediately, and may reduce the inhibitory effects of MMPs on keratinocyte migration.

Abstract
Background Multiple types of assays allow sensitive detection of virus-specific neutralizing antibodies. For example, the extent of antibody neutralization of HIV-1, SIV and SHIV can be measured in the TZM-bl cell line through the degree of luciferase reporter gene expression after infection. In the past, neutralization curves and titers for this standard assay have been calculated using an Excel macro. Updating all instances of such a macro with new techniques can be unwieldy and introduce non-uniformity across multi-lab teams. Using Excel also poses challenges in centrally storing, sharing and associating raw data files and results. Results We present LabKey Server's NAb tool for organizing, analyzing and securely sharing data, files and results for neutralizing antibody (NAb) assays, including the luciferase-based TZM-bl NAb assay. The customizable tool supports high-throughput experiments and includes a graphical plate template designer, allowing researchers to quickly adapt calculations to new plate layouts. The tool calculates the percent neutralization for each serum dilution based on luminescence measurements, fits a range of neutralization curves to titration results and uses these curves to estimate the neutralizing antibody titers for benchmark dilutions. Results, curve visualizations and raw data files are stored in a database and shared through a secure, web-based interface. NAb results can be integrated with other data sources based on sample identifiers. It is simple to make results public after publication by updating folder security settings. Conclusions Standardized tools for analyzing, archiving and sharing assay results can improve the reproducibility, comparability and reliability of results obtained across many labs. LabKey Server and its NAb tool are freely available as open source software at http://www.labkey.com under the Apache 2.0 license. Many members of the HIV research community can also access the LabKey Server NAb tool without installing the software by using the Atlas Science Portal (https://atlas.scharp.org).

Abstract
BACKGROUND Broad-based collaborations are becoming increasingly common among disease researchers. For example, the Global HIV Enterprise has united cross-disciplinary consortia to speed progress towards HIV vaccines through coordinated research across the boundaries of institutions, continents and specialties. New, end-to-end software tools for data and specimen management are necessary to achieve the ambitious goals of such alliances. These tools must enable researchers to organize and integrate heterogeneous data early in the discovery process, standardize processes, gain new insights into pooled data and collaborate securely. RESULTS To meet these needs, we enhanced the LabKey Server platform, formerly known as CPAS. This freely available, open source software is maintained by professional engineers who use commercially proven practices for software development and maintenance. Recent enhancements support: (i) Submitting specimens requests across collaborating organizations (ii) Graphically defining new experimental data types, metadata and wizards for data collection (iii) Transitioning experimental results from a multiplicity of spreadsheets to custom tables in a shared database (iv) Securely organizing, integrating, analyzing, visualizing and sharing diverse data types, from clinical records to specimens to complex assays (v) Interacting dynamically with external data sources (vi) Tracking study participants and cohorts over time (vii) Developing custom interfaces using client libraries (viii) Authoring custom visualizations in a built-in R scripting environment. Diverse research organizations have adopted and adapted LabKey Server, including consortia within the Global HIV Enterprise. Atlas is an installation of LabKey Server that has been tailored to serve these consortia. It is in production use and demonstrates the core capabilities of LabKey Server. Atlas now has over 2,800 active user accounts originating from approximately 36 countries and 350 organizations. It tracks roughly 27,000 assay runs, 860,000 specimen vials and 1,300,000 vial transfers. CONCLUSIONS Sharing data, analysis tools and infrastructure can speed the efforts of large research consortia by enhancing efficiency and enabling new insights. The Atlas installation of LabKey Server demonstrates the utility of the LabKey platform for collaborative research.

Engineering a novel self-powering electrochemical biosensor. SYSTEMS AND SYNTHETIC BIOLOGY 2010; 4:203-14.

Abstract
This paper records the efforts of a multi-disciplinary team of undergraduate students from Glasgow University to collectively design and carry out a 10 week project in Synthetic Biology as part of the international Genetic Engineered Machine competition (iGEM). The aim of the project was to design and build a self-powering electrochemical biosensor called ‘ElectrEcoBlu’. The novelty of this engineered machine lies in coupling a biosensor with a microbial fuel cell to transduce a pollution input into an easily measurable electrical output signal. The device consists of two components; the sensor element which is modular, allowing for customisation to detect a range of input signals as required, and the universal reporter element which is responsible for generating an electrical signal as an output. The genetic components produce pyocyanin, a competitive electron mediator for microbial fuel cells, thus enabling the generation of an electrical current in the presence of target chemical pollutants. The pollutants tested in our implementation were toluene and salicylate. ElectrEcoBlu is expected to drive forward the development of a new generation of biosensors. Our approach exploited a range of state-of-the-art modelling techniques in a unified framework of qualitative, stochastic and continuous approaches to support the design and guide the construction of this novel biological machine. This work shows that integrating engineering techniques with scientific methodologies can provide new insights into genetic regulation and can be considered as a reference framework for the development of biochemical systems in synthetic biology.
