Defining acceptable data collection and reuse standards for queer artificial intelligence research in mental health: protocol for the online PARQAIR-MH Delphi study

Por: Joyce · D. W. · Kormilitzin · A. · Hamer-Hunt · J. · McKee · K. R. · Tomasev · N.
Introduction

For artificial intelligence (AI) to help improve mental healthcare, the design of data-driven technologies needs to be fair, safe, and inclusive. Participatory design can play a critical role in empowering marginalised communities to take an active role in constructing research agendas and outputs. Given the unmet needs of the LGBTQI+ (Lesbian, Gay, Bisexual, Transgender, Queer and Intersex) community in mental healthcare, there is a pressing need for participatory research to include a range of diverse queer perspectives on issues of data collection and use (in routine clinical care as well as for research) as well as AI design. Here we propose a protocol for a Delphi consensus process for the development of PARticipatory Queer AI Research for Mental Health (PARQAIR-MH) practices, aimed at informing digital health practices and policy.

Methods and analysis

The development of PARQAIR-MH is comprised of four stages. In stage 1, a review of recent literature and fact-finding consultation with stakeholder organisations will be conducted to define a terms-of-reference for stage 2, the Delphi process. Our Delphi process consists of three rounds, where the first two rounds will iterate and identify items to be included in the final Delphi survey for consensus ratings. Stage 3 consists of consensus meetings to review and aggregate the Delphi survey responses, leading to stage 4 where we will produce a reusable toolkit to facilitate participatory development of future bespoke LGBTQI+–adapted data collection, harmonisation, and use for data-driven AI applications specifically in mental healthcare settings.

Ethics and dissemination

PARQAIR-MH aims to deliver a toolkit that will help to ensure that the specific needs of LGBTQI+ communities are accounted for in mental health applications of data-driven technologies. The study is expected to run from June 2024 through January 2025, with the final outputs delivered in mid-2025. Participants in the Delphi process will be recruited by snowball and opportunistic sampling via professional networks and social media (but not by direct approach to healthcare service users, patients, specific clinical services, or via clinicians’ caseloads). Participants will not be required to share personal narratives and experiences of healthcare or treatment for any condition. Before agreeing to participate, people will be given information about the issues considered to be in-scope for the Delphi (eg, developing best practices and methods for collecting and harmonising sensitive characteristics data; developing guidelines for data use/reuse) alongside specific risks of unintended harm from participating that can be reasonably anticipated. Outputs will be made available in open-access peer-reviewed publications, blogs, social media, and on a dedicated project website for future reuse.

Prevalence of the use of oral nutritional supplements among acute inpatients at risk of malnutrition and associated patient characteristics

Abstract

Aim

To provide a snapshot of the current use of oral nutritional supplements, its association with inpatient characteristics, and with a focus on the role of nursing monitoring of food intake and implementing nutritional interventions for patients with low intake.

Design

Retrospective cohort study.

Methods

The study collected data from a hospital database regarding oral nutritional supplement initiation and variables of patients hospitalised in internal medicine departments, who did not receive enteral or parenteral nutrition.

Results

Of the 5155 admissions, 1087 fulfilled the inclusion criteria (47% female; mean age, 72.4 ± 14.6 years; mean length of stay, 14.6 ± 11.4 days). Sufficient food intake reporting was noted in 74.6% of the patients; of these 17% had decreased intake. Oral nutritional supplements and non-oral nutritional supplements groups did not differ in terms of sex, age, length of stay, Charlson Comorbidity Index, proportion of nursing reports, and absence of intake monitoring. Oral nutritional supplements were initiated in 31.9% of patients with a Malnutrition Universal Screening Tool score ≥2 and in 34.6% with decreased food intake. On multivariable analysis, hypoalbuminemia (adjusted odds ratio, 3.70), decreased food intake (adjusted odds ratio, 3.38), Malnutrition Universal Screening Tool score ≥2 (adjusted odds ratio, 2.10), and age <70 years (adjusted odds ratio, 1.56) were significantly associated with oral nutritional supplements use.

Conclusion

The prevalence of oral nutritional intervention was suboptimal in patients at risk of malnutrition during acute hospitalisation, although decreased food intake and Malnutrition Universal Screening Tool score ≥2 independently increased the probability of oral nutritional supplements initiation.

Relevance in clinical practice

Understanding the clinical practice and nursing impact of care management in relation to nutritional intervention can assist in reviewing and improving patient care.

Implications for the profession and/or patient care Impact (Addressing)

This study informs clinical management and influences nursing practice standards related to assessing, monitoring, and managing malnutrition risk.

Impact

The study impacts the quality of care for patients at risk of malnutrition.

Reporting Method

We adhered to the STROBE Checklist for cohort studies.

Ultrasound tomography enhancement by signal feature extraction with modular machine learning method

by Bartłomiej Baran, Dariusz Majerek, Piotr Szyszka, Dariusz Wójcik, Tomasz Rymarczyk

Robust and reliable diagnostic methods are desired in various types of industries. This article presents a novel approach to object detection in industrial or general ultrasound tomography. The key idea is to analyze the time-dependent ultrasonic signal recorded by three independent transducers of an experimental system. It focuses on finding common or related characteristics of these signals using custom-designed deep neural network models. In principle, models use convolution layers to extract common features of signals, which are passed to dense layers responsible for predicting the number of objects or their locations and sizes. Predicting the number and properties of objects are characterized by a high value of the coefficient of determination R2 = 99.8% and R2 = 98.4%, respectively. The proposed solution can result in a reliable and low-cost method of object detection for various industry sectors.

A non-lethal stable isotope analysis of valued freshwater predatory fish using blood and fin tissues as alternatives to muscle tissue

by Lukáš Vejřík, Ivana Vejříková, Zuzana Sajdlová, Luboš Kočvara, Tomáš Kolařík, Daniel Bartoň, Tomáš Jůza, Petr Blabolil, Jiří Peterka, Martin Čech, Mojmír Vašek

Stable isotope analysis (SIA) is widely used to study trophic ecology and food webs in aquatic ecosystems. In the case of fish, muscle tissue is generally preferred for SIA, and the method is lethal in most cases. We tested whether blood and fin clips can be used as non-lethal alternatives to muscle tissue for examining the isotopic composition of two freshwater predatory fish, European catfish (Silurus glanis) and Northern pike (Esox lucius), species of high value for many freshwater systems as well as invasive species in many others. Blood samples from the caudal vein, anal fin clips, and dorsal muscle obtained by biopsy punch were collected from four catfish and pike populations (14–18 individuals per population). Subsequently, these samples were analyzed for δ13C and δ15N. The effects of alternative tissues, study site, and fish body mass on the isotopic offset were investigated. Both species showed a correlation between the isotopic offset and the tissue type, as well as the study site, but no significant relationship with the body mass. The isotopic offsets between tissues were used to calculate the conversion equations. The results demonstrated that both blood and fin clips are suitable and less invasive alternative to muscle in SIA studies focused on European catfish and Northern pike. Blood provided better correspondence to muscle isotope values. However, our results clearly demonstrated that isotopic offsets between tissues vary significantly among populations of the same species. Therefore, obtaining a muscle biopsy from several individuals in any population is advisable to gain initial insights and establish a possible population-specific inter-tissue conversion.

AGO2-RIP-Seq reveals miR-34/miR-449 cluster targetome in sinonasal cancers

by Marco Tomasetti, Federica Monaco, Corrado Rubini, Marzia Rossato, Concetta De Quattro, Cristina Beltrami, Giacomo Sollini, Ernesto Pasquini, Monica Amati, Gaia Goteri, Lory Santarelli, Massimo Re

Sinonasal tumours are heterogeneous malignancies, presenting different histological features and clinical behaviour. Many studies emphasize the role of specific miRNA in the development and progression of cancer, and their expression profiles could be used as prognostic biomarkers to predict the survival. Recently, using the next-generation sequencing (NGS)-based miRNome analysis the miR-34/miR-449 cluster was identified as miRNA superfamily involved in the pathogenesis of sinonasal cancers (SNCs). In the present study, we established an Argonaute-2 (AGO2): mRNA immunoprecipitation followed by high-throughput sequencing to analyse the regulatory role of miR-34/miR-449 in SNCs. Using this approach, we identified direct target genes (targetome), which were involved in regulation of RNA-DNA metabolic, transcript and epigenetic processes. In particular, the STK3, C9orf78 and STRN3 genes were the direct targets of both miR-34c and miR-449a, and their regulation are predictive of tumour progression. This study provides the first evidence that miR-34/miR-449 and their targets are deregulated in SNCs and could be proposed as valuable prognostic biomarkers.

Family members' experiences of COVID‐19 visiting restrictions in the intensive care unit—A qualitative study

Abstract

Objective

To describe how family members of critically ill patients experienced the COVID-19 visiting restrictions in Sweden.

Background

In Sweden, the response to COVID-19 was less invasive than in many other countries. However, some visiting restrictions were introduced for intensive care units, with local variations. Although there is a growing body of literature regarding healthcare professionals' and family caregivers' perspectives on visiting restriction policies, there may be inter-country differences, which remain to be elucidated.

Design

This study has a qualitative descriptive design. Focus group interviews with 14 family members of patients treated for severe COVID-19 infection were conducted. The interviews took place via digital meetings during the months after the patients' hospital discharge. Qualitative content analysis was used to interpret the interview transcripts. Reporting of the study followed the COREQ checklist.

Results

Two categories—dealing with uncertainty and being involved at a distance—described family members' experiences of coping with visiting restrictions during the COVID-19 pandemic. These restrictions were found to reduce family members' ability to cope with the situation. Communication via telephone or video calls to maintain contact was appreciated but could not replace the importance of personal contact.

Conclusions

Family members perceived that the visiting restriction routines in place during the COVID-19 pandemic negatively influenced their ability to cope with the situation and to achieve realistic expectations of the patients' needs when they returned home.

Relevance to Clinical Practice

This study suggests that, during the COVID-19 pandemic, the visiting restrictions were experienced negatively by family members and specific family-centred care guidelines need to be developed for use during crises, including the possibility of regular family visits to the ICU.

Patient and Public Contribution

The role of basic psychological needs in the relationships between identity orientations and adolescent mental health: A protocol for a longitudinal study

by Veljko Jovanović, Aleksandar Tomašević, Dušana Šakan, Milica Lazić, Vesna Gavrilov-Jerković, Marija Zotović-Kostić, Vojana Obradović

Research into the role of identity orientations (the relative importance an individual places on different personal and social attributes and characteristics when defining her or his identity) in adolescent mental health is extremely limited. Furthermore, the potential mechanisms that might explain the associations between identity orientations and adolescent mental health are poorly understood. This study protocol describes a one-year longitudinal study across three time points to be initiated with the purpose of investigating the mediating role of basic psychological needs satisfaction and frustration in the relationship between identity orientations and various mental health indicators in adolescence. We aim to recruit a large sample of Serbian adolescents (N = 2,000 at Time 1), using a two-stage stratified random sampling. The data will be analyzed using the random intercept cross-lagged panel model (RI-CLPM), and the results will be contrasted with the traditional CLPM. The goal of this study is to make a theoretical contribution to research in the fields of identity, self-determination theory, and adolescent mental health, as well as to provide insights towards the development of evidence-based recommendations for creating prevention and promotion programs aimed at improving the well-being of adolescents.

Two distinct <i>Fusarium graminearum</i> populations colonized European wheat in the past two decades

by Tomasz Kulik, Tomasz Molcan, Katarzyna Bilska, Marco Beyer, Matias Pasquali, Anne van Diepeningen, Kamil Myszczynski

Fusarium graminearum is the main causal agent of Fusarium head blight (FHB) disease in wheat in Europe. To reveal population structure and to pinpoint genetic targets of selection we studied genomes of 96 strains of F. graminearum using population genomics. Bayesian and phylogenomic analyses indicated that the F. graminearum emergence in Europe could be linked to two independently evolving populations termed here as East European (EE) and West European (WE) population. The EE strains are primarily prevalent in Eastern Europe, but to a lesser extent also in western and southern areas. In contrast, the WE population appears to be endemic to Western Europe. Both populations evolved in response to population-specific selection forces, resulting in distinct localized adaptations that allowed them to migrate into their environmental niche. The detection of positive selection in genes with protein/zinc ion binding domains, transcription factors and in genes encoding proteins involved in transmembrane transport highlights their important role in driving evolutionary novelty that allow F. graminearum to increase adaptation to the host and/or environment. F. graminearum also maintained distinct sets of accessory genes showing population-specific conservation. Among them, genes involved in host invasion and virulence such as those encoding proteins with high homology to tannase/feruloyl esterase and genes encoding proteins with functions related to oxidation-reduction were mostly found in the WE population. Our findings shed light on genetic features related to microevolutionary divergence of F. graminearum and reveal relevant genes for further functional research aiming at better control of this pathogen.

Effect of screw angulation and multiple insertions on load-to-failure of polyaxial locking system

by Jakub Glowacki, Tomasz Bartkowiak, Piotr Paczos, Patryk Mietlinski, Pawel Zawadzki, Lukasz Lapaj

Purpose

Polyaxial locking plates rely on the alignment between the thread-to-thread connections of the screw head and the plate hole. These implants have provided substantial support for surgeons. In particular, extended screw positioning have proven to be beneficial in the fixation of challenging fractures. This study aimed to investigate the mechanical properties of ChM 5.0 ChLP polyaxial screws inserted in off-axis trajectories, including multiple insertions and to correlate these parameters with the screw head and the plate hole thread-to-thread engagement.

Methods

Polyaxial locking screws were inserted into the plates at various angles (0°,10°,15°, -15° off-axis). Multiple time inserted screws were placed firstly at 15°, then 0° and finally -15° off-axis in the same plate hole. A microCT scan of the plate-hole and screw-head interface was conducted before destructive tests. Representative screws from each group were also examined by Scanning Electron Microscope.

Results

The standard insertion at 0° sustained the greatest maximum bending strength without relocation in the screw hole. Screws inserted at 10° and 15° (one time) showed a significant reduction in load-to-failure of up to 36% and 55%, (p = 0.001) (p = 0.001) respectively. Screws inserted at -15° after a maximum of three multiple insertions with angle shift, showed a total reduction in force of up to 70% (p = 0.001). A microCT analysis of thread engagement showed significant correlations. However, the results obtained for multiple insertions were highly variable.

Conclusions

ChM 5.0 ChLP polyaxial locking system has valuable properties that foster fracture fixation, providing various surgical options. Nevertheless, the freedom of off-axis placement and multiple insertions of the screws comes at the price of reduced force. When possible surgeons should minimize the angles of insertions.

Effects of 36 hours of sleep deprivation on military-related tasks: Can ammonium inhalants maintain performance?

by Jan Maleček, Dan Omcirk, Kateřina Skálová, Jan Pádecký, Martin Tino Janikov, Michael Obrtel, Michal Jonáš, David Kolář, Vladimír Michalička, Karel Sýkora, Michal Vágner, Lubomír Přívětivý, Tomáš Větrovský, Zdeňka Bendová, Vít Třebický, James J. Tufano

Introduction

A lack of sleep can pose a risk during military operations due to the associated decreases in physical and cognitive performance. However, fast-acting ergogenic aids, such as ammonia inhalants (AI), may temporarily mitigate those adverse effects of total sleep deprivation (TSD). Therefore, the present study aimed to investigate the acute effect of AI on cognitive and physical performance throughout 36 hours of TSD in military personnel.

Methods

Eighteen male military cadets (24.1 ± 3.0 y; 79.3 ± 8.3 kg) performed 5 identical testing sessions during 36 hours of TSD (after 0 [0], 12 [–12], 24 [–24], and 36 [–36] hours of TSD), and after 8 [+8] hours of recovery sleep. During each testing session, the following assessments were conducted: Epworth sleepiness scale (ESS), simple reaction time (SRT), shooting accuracy (SA), rifle disassembling and reassembling (DAS), and countermovement jump height (JH). Heart rate (HR) was continuously monitored during the SA task, and a rating of perceived exertion (RPE) was obtained during the JH task. At each time point, tests were performed twice, either with AI or without AI as control (CON), in a counterbalanced order.

Results

There was faster SRT (1.6%; p 0.05). Independent of AI, the SRT was slower (3.2–9.3%; p Conclusion

Although there were detrimental effects of TSD, the usage of AI did not reduce those adverse effects. However, regardless of TSD, AI did result in a short-term increase in HR, improved SRT without affecting the number of errors, and improved JH while concurrently decreasing the RPE. No changes, yet, were observed in SA and DAS. These results suggest that AI could potentially be useful in some military scenarios, regardless of sleep deprivation.

Cuidados Profesionales en una Residencia de Mayores durante la Covid-19

Objetivo principal: Analizar la importancia de los cuidados emocionales y las carencias que ha ocasionado la Pandemia de la COVID-19 en los últimos 6 meses. Metodología: Es una reflexión tras un relato estructurado entre tres enfermeras, dos de ella implicadas en los cuidados durante la pandemia de la COVID. Resultados principales: Se ha priorizado el cuidado físico, y se ha secundarizado el bienestar emocional debido a factores como la pérdida de las visitas familiares, la falta de las cuidadoras (TAE) habituales, falta de personal en enfermería profesional. Conclusión principal: La pandemia ha afectado a los Residentes de forma que se aprecian carencias cognitivas y socioafectivas. La epidemia durante estos seis meses nos ha demostrado que no es suficiente tener una residencia: de amplios espacios, edificio sostenible, limpio y con un buen equipo, ya que el cuidado emocional no se ha sabido y/o podido cubrir de forma adecuada.
