RESUMEN

BACKGROUND: Acupuncture is a promising modality in clinical practice, where the participants' experiences are crucial to acupuncture's use and effects. However, a comprehensive review synthesising participant experiences throughout treatment sessions is lacking. This study aims to explore the qualitative literature regarding participants' experiences of acupuncture as a potential treatment modality. METHODS: A qualitative systematic review of existing literature was conducted through AMED, MEDLINE, Scopus, Embase, and Web of Science. The Joanna Briggs Institute (JBI) critical appraisal checklist was employed to evaluate research quality. Subsequently, the data were extracted and synthesised utilising the JBI Qualitative Assessment and Review Instrument (QARI) tool and data synthesis was carried out through meta-aggregation. RESULTS: A total of twenty-eight articles were incorporated into the analysis. Four synthesised findings were identified: (1) Before acupuncture: last trust and hope; (2) During acupuncture: relaxing and calming; (3) After acupuncture: mind-body effects; and (4) Practitioner-participant relationship. CONCLUSION: The findings highlight the changes participants experienced before and after acupuncture sessions. Implementing additional promotional initiatives for acupuncture can increase public awareness and encourage individuals to consider it an early symptom management option. REVIEW REGISTRATION: This review was registered in PROSPERO (No. CRD42023475373).

RESUMEN

Machine learning is a valuable tool that can accelerate the discovery and design of materials occupying combinatorial chemical spaces. However, the prerequisite need for vast amounts of training data can be prohibitive when significant resources are needed to characterize or simulate candidate structures. Recent results have shown that structure-free encoding of complex materials, based entirely on chemical compositions, can overcome this impediment and perform well in unsupervised learning tasks. In this study, we extend this exploration to supervised classification, and show how structure-free encoding can accurately predict classes of material compounds for battery applications without time consuming measurement of bonding networks, lattices or densities. SCIENTIFIC CONTRIBUTION: The comprehensive evaluation of structure-free encodings of complex materials in classification tasks, including binary and multi-class separation, inclusive of three classifiers based on different logic function, is measured four metrics and learning curves. The encoding is applied to two data sets from computational and experimental sources, and the outcomes visualised using 5 approaches to confirms the suitability and superiority of Mendeleev encoding. These methods are general and accessible using source software, to provide simple, intuitive and interpretable materials informatics outcomes to accelerate materials design.

RESUMEN

AIMS: To explore and summarise the literature on the concept of 'clinical deterioration' as a nurse-sensitive indicator of quality of care in the out-of-hospital context. DESIGN: The scoping review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review and the JBI best practice guidelines for scoping reviews. METHODS: Studies focusing on clinical deterioration, errors of omission, nurse sensitive indicators and the quality of nursing and midwifery care for all categories of registered, enrolled, or licensed practice nurses and midwives in the out-of-hospital context were included regardless of methodology. Text and opinion papers were also considered. Study protocols were excluded. DATA SOURCES: Data bases were searched from inception to June 2022 and included CINAHL, PsychINFO, MEDLINE, The Allied and Complementary Medicine Database, EmCare, Maternity and Infant Care Database, Australian Indigenous HealthInfoNet, Informit Health and Society Database, JSTOR, Nursing and Allied Health Database, RURAL, Cochrane Library and Joanna Briggs Institute. RESULTS: Thirty-four studies were included. Workloads, education and training opportunities, access to technology, home visits, clinical assessments and use of screening tools or guidelines impacted the ability to recognise, relay information and respond to clinical deterioration in the out-of-hospital setting. CONCLUSIONS: Little is known about the work of nurses or midwives in out-of-hospital settings and their recognition, reaction to and relay of information about patient deterioration. The complex and subtle nature of non-acute deterioration creates challenges in defining and subsequently evaluating the role and impact of nurses in these settings. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Further research is needed to clarify outcome measures and nurse contribution to the care of the deteriorating patient in the out-of-hospital setting to reduce the rate of avoidable hospitalisation and articulate the contribution of nurses and midwives to patient care. IMPACT: What Problem Did the Study Address? Factors that impact a nurse's ability to recognise, relay information and respond to clinical deterioration in the out-of-hospital setting are not examined to date. What Were the Main Findings? A range of factors were identified that impacted a nurse's ability to recognise, relay information and respond to clinical deterioration in the out-of-hospital setting including workloads, education and training opportunities, access to technology, home visits, clinical assessments, use of screening tools or guidelines, and avoidable hospitalisation. Where and on whom will the research have an impact? Nurses and nursing management will benefit from understanding the factors that act as barriers and facilitators for effective recognition of, and responding to, a deteriorating patient in the out-of-hospital setting. This in turn will impact patient survival and satisfaction. REPORTING METHOD: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review guidelines guided this review. The PRISMA-Scr Checklist (Tricco et al., 2018) is included as (supplementary file 1).Data sharing is not applicable to this article as no new data were created or analysed in this study." NO PATIENT OR PUBLIC CONTRIBUTION: Not required as the Scoping Review used publicly available information.

RESUMEN

The youth (15-24 years old) in South Africa remain at high risk of HIV infection despite varied efforts to control the disease. An understanding of the perspectives of relevant stakeholders of HIV-prevention interventions targeting the youth is important to guide research, policy and practice aimed at improving these interventions. This study explores youth and intervention implementers' perceptions of a resilience-based HIV-prevention intervention (You Only Live Once) aimed at reducing risky sexual behaviours among the youth in South Africa. Semi-structured interviews were conducted with 10 young people who participated in the intervention, and four intervention implementers at a not-for-profit organisation in Maluti-a-Phofung Local Municipality, South Africa. Data were analysed using thematic analysis. Three main themes emerged from the data: (1) Acceptability and impact of the intervention; (2) Factors influencing intervention implementation; and (3) Recommendations to improve intervention implementation. These findings provide insights into the acceptability, impact, barriers and facilitators of resilience-based HIV-prevention interventions for the youth in South Africa and similar contexts, and how implementation of these interventions could be enhanced. The findings can help researchers, policy makers and health care practitioners in the field of HIV prevention to improve interventions targeting young people.

RESUMEN

Understanding the polydispersity of nanoparticles is crucial for establishing the efficacy and safety of their role as drug delivery carriers in biomedical applications. Detonation nanodiamonds (DNDs), 3-5 nm diamond nanoparticles synthesized through detonation process, have attracted great interest for drug delivery due to their colloidal stability in water and their biocompatibility. More recent studies have challenged the consensus that DNDs are monodispersed after their fabrication, with their aggregate formation poorly understood. Here, we present a novel characterization method of combining machine learning with direct cryo-transmission electron microscopy imaging to characterize the unique colloidal behavior of DNDs. Together with small-angle X-ray scattering and mesoscale simulations we show and explain the clear differences in the aggregation behavior between positively and negatively charged DNDs. Our new method can be applied to other complex particle systems, which builds essential knowledge for the safe implementation of nanoparticles in drug delivery.

RESUMEN

OBJECTIVES: In Australia, Aboriginal children experience disproportionate rates of type 2 diabetes (T2D) compared with non-Aboriginal children. The aim of this qualitative study was to explore the experiences of Aboriginal adolescents with T2D and their family members to better understand the influences of T2D on self-management, with findings used to inform an enhanced service model of care. METHODS: Semistructured interviews were conducted with purposively selected Western Australian Aboriginal adolescents with T2D and their parents and guardians. Interviews were transcribed verbatim and analyzed with NVivo software using interpretative thematic analysis; overarching themes were generated. RESULTS: Interviews with 24 participants, including 8 adolescents aged 11 to 16 years, were conducted across 4 regions of Western Australia. A high proportion of these adolescents were diagnosed with T2D during an unrelated hospitalization or medical appointment. Most did not fully understand or were unaware of the long-term impact of T2D. Discussions about diabetes within families did not typically occur, and shame and concealment of the diagnosis was a common finding. The parents of the adolescents described the diagnosis of T2D as compounding an already challenging set of circumstances for the family; this impacted their capacity to promote self-management activities and attend hospital and outpatient appointments. CONCLUSIONS: This study privileges the voices of Aboriginal adolescents and family members and offers insight into their personal narrative of living with T2D. Building family and community capacity to normalize preventive activities and manage T2D postdiagnosis is recommended to improve health outcomes.

RESUMEN

OBJECTIVE: Ovarian cancer is a significant health issue with lasting impacts on the community. Despite recent advances in surgical, chemotherapeutic and radiotherapeutic interventions, they have had only marginal impacts due to an inability to identify biomarkers at an early stage. Biomarker discovery is challenging, yet essential for improving drug discovery and clinical care. Machine learning (ML) techniques are invaluable for recognising complex patterns in biomarkers compared to conventional methods, yet they can lack physical insights into diagnosis. eXplainable Artificial Intelligence (XAI) is capable of providing deeper insights into the decision-making of complex ML algorithms increasing their applicability. We aim to introduce best practice for combining ML and XAI techniques for biomarker validation tasks. METHODS: We focused on classification tasks and a game theoretic approach based on Shapley values to build and evaluate models and visualise results. We described the workflow and apply the pipeline in a case study using the CDAS PLCO Ovarian Biomarkers dataset to demonstrate the potential for accuracy and utility. RESULTS: The case study results demonstrate the efficacy of the ML pipeline, its consistency, and advantages compared to conventional statistical approaches. CONCLUSION: The resulting guidelines provide a general framework for practical application of XAI in medical research that can inform clinicians and validate and explain cancer biomarkers.

RESUMEN

AIMS: This work aims to explore staff perceptions of (1) the effectiveness of organizational communication during the COVID-19 pandemic and (2) the impact of organizational communication on staff well-being and ability to progress their work and patient care. BACKGROUND: Effective coordination and communication are essential in a pandemic management response. However, the effectiveness of communication strategies used during the COVID-19 pandemic is not well understood. DESIGN: An exploratory cross-sectional research design was used. A 33-item survey tool was created for the study. METHODS: The study was conducted at a tertiary teaching hospital in Western Australia. Convenience sampling was used to recruit participants from nursing, medical, allied health services, administrative and clerical, and personal support services (N = 325). Data were collected between December 2020 and May 2021. RESULTS: Overall, all occupational groups found working during the COVID-19 pandemic stressful, and all groups wanted accessible and accurate communication from management and new policies, procedures, and protocols for future outbreaks. CONCLUSIONS: The use of occupational group-relevant strategies and COVID-19 protocols, as well as the on-going use of email, face-to-face meetings with debrief sessions, are needed to improve communication and support staff to fulfil their roles.

RESUMEN

Aluminium (Al) alloys are critical to many applications. Although Al alloys have been commercially widespread for over a century, their development has predominantly taken a trial-and-error approach. Furthermore, many discrete studies regarding Al alloys, often application specific, have precluded a broader consolidation of Al alloy classification. Iterative label spreading (ILS), an unsupervised machine learning approach, was used to identify the different classes of Al alloys, drawing from a specifically curated dataset of 1154 Al alloys (including alloy composition and processing conditions). Using ILS, eight classes of Al alloys were identified based on a comprehensive feature set under two descriptors. Further, a decision tree classifier was used to validate the separation of classes.

RESUMEN

Bat coronaviruses (CoVs) are extremely prevalent throughout the globe and exhibit a wide range of genetic diversity. Currently, little is known about the susceptibility of New World bats to severe acute respiratory syndrome-2 (SARS-CoV-2), the causative agent of COVID-19. Also, there is limited information about the genetic diversity of other CoVs in the New World bats. The determination of genetic diversity of bat CoVs through continuous surveillance is essential to predict and mitigate the emergence of new CoVs and their impacts on the health of both humans and animals. In this study, 491 guano specimens collected from New World bats and 37 specimens collected from Old World bats during July 2020 to July 2021 were tested for SARS-COV-2 and other CoVs using a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) panel and pan-coronavirus PCR that target a highly conserved region of CoVs. No evidence of SARS-CoV-2 was found in the tested specimens. An alpha CoV was detected in a single specimen from a big brown bat (Eptesicus fuscus). This information was used by wildlife agencies and rehabilitation facilities to permit the release of bats during the pandemic while mitigating the risk of spreading SARS-CoV-2 among North American bats and other wild animal populations.

RESUMEN

The COVID-19 pandemic mandated a substantial switch in primary health care delivery from an in-person to a mainly remote telephone or video service. As the COVID-19 pandemic approaches its third year, limited progress appears to have been made in terms of policy development around consultation methods for the post-acute phase of the pandemic. In September 2020, the International Primary Care Respiratory Group convened a global panel of primary care clinicians - including family physicians, paediatricians, pharmacists, academics and patients - to consider the policy and health management implications of the move to remote consultations in the primary care setting. The group gave special consideration to how and how far remote consultations should be integrated into routine primary health care delivery. Remote consultations can be a useful alternative to in-person consultations in primary care not only in situations where there is a need for viral infection control but also for the routine delivery of chronic disease management. However, they may not be more time efficient for the clinician, and they can add to the workload and work-related stress for primary care practitioners if they remain the dominant consultation mode. Remote consultations are also less appropriate than in-person consultations for new disease diagnosis, dealing with multiple issues and providing complex care. Ensuring health care professionals have the appropriate skill set to effectively deliver remote consultations, administrative and/or IT support and appropriate reimbursement will be key to achieving optimal integration of remote consultations into routine clinical practice. Addressing digital access and digital literacy issues at a societal level will also be essential to ensure individuals have fair and equitable access to the internet and sufficient security for exchange of personal and health-related data.

RESUMEN

In nature, snowflake ice crystals arrange themselves into diverse symmetrical six-sided structures. We show an analogy of this when zinc (Zn) dissolves and crystallizes in liquid gallium (Ga). The low-melting-temperature Ga is used as a "metallic solvent" to synthesize a range of flake-like Zn crystals. We extract these metallic crystals from the liquid metal solvent by reducing its surface tension using a combination of electrocapillary modulation and vacuum filtration. The liquid metal-grown crystals feature high morphological diversity and persistent symmetry. The concept is expanded to other single and binary metal solutes and Ga-based solvents, with the growth mechanisms elucidated through ab initio simulation of interfacial stability. This strategy offers general routes for creating highly crystalline, shape-controlled metallic or multimetallic fine structures from liquid metal solvents.

RESUMEN

PURPOSE: Interventions focused on promoting resilience or protective factors of youth have been proposed as a strategy for reducing risky behaviours associated with HIV infection among youth; however few studies have explored their effectiveness. This study assessed the impact of a resilience-based HIV prevention intervention (You Only Live Once) on risky sexual behaviours, resilience and protective factors of youth. METHODS: A one-group pretest-posttest design was used. One hundred and ninety-seven youth aged 15-24 years were conveniently recruited from a non-profit organisation in Maluti-a-Phofung Local Municipality, South Africa and participated in a 12-session, resilience-based HIV intervention delivered over a 1-week period by trained adult facilitators. Outcomes of interest were assessed at baseline and 3-month follow-up using validated risky sexual behaviour measures, and Child and Youth Resilience Measure. Mixed effect logistic and linear regression models were formulated to assess the impact of the intervention on risky sexual behaviours; resilience and protective factors respectively. RESULTS: Compared to baseline, participants at 3-month follow-up were 68 % less likely to have unprotected sex, 22 % less likely to regret their decision to engage in sexual activity and 0.4 % less likely to be pregnant or made someone pregnant. Conversely, participants at the 3-month follow-up had a higher propensity to engage in multiple sexual partnerships, transactional sex and intergenerational sex than baseline. Participants at 3-month follow-up had significant improvements in their scores of resilience, individual capacities and contextual factors that facilitate a sense of belonging (p < 0.05). CONCLUSION: You Only Live Once intervention appeared to have mitigated some risky sexual behaviours, and improved resilience and protective factors over a 3-month period. These findings suggest that the intervention has ability to reduce risky sexual behaviours associated with HIV, and improve resilience and protective factors among youth in South Africa. Further evaluation of the intervention with a rigorous study design, larger sample size and longer period for follow-up is warranted.

RESUMEN

BACKGROUND: Accelerated by the coronavirus disease 2019 (COVID-19) pandemic, Australia has shifted towards greater use of telehealth to deliver care for rural and remote communities. This policy direction might risk a shift away from the traditional model of informed person-centred care built around care relationships to a technology-mediated health transaction. Potential opportunity costs of widespread telehealth services on the quality of care for rural and remote communities remain understudied. METHODS: A qualitative study was conducted in three local health districts of rural New South Wales, Australia. Data were collected through in-depth interviews. A total of 13 participants was interviewed. Data were analysed using thematic analysis. RESULTS: Patient participants perceived telehealth as an alternative when specialist care was limited or absent. Both patients and clinicians perceived that the deeper caring relationship, enabled through face-to-face interactions, could not be achieved through telehealth services alone, and that telehealth services are often superficial and fragmented in nature. Patients in this study contended that virtual consultations can be distant and lacking in personal touch, and risk losing sight of social circumstances related to patients' health, thereby affecting the trust placed in healthcare systems. CONCLUSIONS: Simply replacing face-to-face interactions with telehealth services has the potential to reduce trust, continuity of care, and effectiveness of rural health services. Telehealth must be used to assist local clinicians in providing the best possible care to rural and remote patients within an integrated service delivery model across diverse rural contexts in Australia.

RESUMEN

BACKGROUND: Interventions aimed at reducing risky sexual behavior are considered an important strategy for averting Human Immunodeficiency Virus (HIV) infection among youth (15-24 years) who continue to be at risk of the disease. Enhancing intervention success requires a comprehensive understanding of the barriers and facilitators to interventions targeting youth. However, there is lack of a systematic review of both quantitative and qualitative studies to comprehensively identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth worldwide. This review aimed to identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth globally based on original peer-reviewed studies published in the last decade. METHODS: The Joanna Briggs Institute approach for mixed methods systematic reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used to guide this review. Nine electronic databases, Joint United Nations Programme on HIV/AIDS and World Health Organization websites, and reference lists of included studies and systematic reviews on barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth were searched for eligible articles. Studies that met the inclusion criteria underwent quality appraisal and data extraction. Findings were analyzed using thematic synthesis and underpinned by Nilsen, 2015's Determinant Framework. RESULTS: Overall 13 studies comprising of eight qualitative studies, four quantitative studies and one mixed methods study were included in the review. Several barriers and facilitators across the five Determinant Framework domains were identified. Most of the barriers fell under the characteristics of the context domain (e.g., gender-biased norms). The next important group of barriers emerged within the characteristics of the end users domain (e.g., fear of relationship breakdown). In terms of facilitators, the majority fell under the characteristics of the strategy of facilitating implementation domain (e.g., implementation of intervention with fidelity) and characteristics of the end users domain (e.g., fear of pregnancy or sexually transmitted infections). The next common set of facilitators appeared within the characteristics of the context domain (e.g., family support). CONCLUSION: This review identified several multi-level barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth. Multi-level and combination approaches are needed to address these factors and enhance intervention success.

RESUMEN

Background: In rural and remote Australia, general practitioners (GPs) provide care across the continuum from primary to secondary care, often in Visiting Medical Officer (VMO) arrangements with a local hospital. However, little is known about the role of GP-VMOs in improving the perceived quality of care and health outcomes for rural and remote communities. Methods: We collected qualitative data from three GP-VMOs (all aged >55 years) and 10 patients (all aged over 65 years) in three local health districts of New South Wales, Australia. Thirteen in-depth interviews were conducted between October 2020 and February 2021. We employed thematic analysis to identify key roles of GP-VMOs in improving the perceived quality of care and health outcomes of rural and remote patients. Results: Our study advances the current understanding regarding the role of GP-VMOs in improving the perceived quality of services and health outcomes of rural and remote patients. Key roles of GP-VMOs in improving the perceived quality of care include promoting the continuity of care and integrated health services, cultivating trust from local communities, and enhancing the satisfaction of patients. Conclusions: GP-VMOs work across primary and secondary care creating better linkages and promoting the continuity of care for rural and remote communities. Employing GP-VMOs in rural hospitals enables the knowledge and sensitivity gained from their ongoing interactions with patients in primary care to be effectively utilised in the delivery of hospital care.

RESUMEN

The economic and social future of nanotechnology depends on our ability and manufacture nanomaterials that avoid potential toxicity, by identifying them before they are made, used and released into the environment. Safety-by-design is a framework for including these issues at an early stage of the development process, but balancing multiple nanoparticle properties and selection criteria remains challenging. Based on a synthetic data set of over 19,000 possible sunscreen product specifications, we have used multi-target machine learning to predict the corresponding size, shape, concentration and polytype of titania nanoparticle additives. The study considers the optical properties responsible for the sun protection factor and product transparency, including the extinction coefficients for ultra violet and visible light, and the potential for toxicity due to the generation of reactive oxygen species from the photocatalytically active facets of both anatase and rutile nanoparticles, as a function of the size and shape. We predict a number of conventional forward structure/property and property/product relationships, but show that a direct structure/product relationship provides superior performance when predicting multiple properties or product specifications simultaneously. These models are then inverted, re-optimized and re-trained to provide focused, high performing inverse design models that do not require additional optimization, and are capable of identifying nanoparticle configurations outside of the training set. The ability to directly predict suitable nanoparticle structures that conform to prerequisite sun protection, transparently and potential toxicity thresholds represents a new approach to safety-by-design that can be applied to other products and materials where multiple design criteria must be met at the same time.

RESUMEN

Adults who experience homelessness for an extended period of time also experience accelerated ageing and other negative impacts on their general health and wellbeing. Homelessness amongst older adults is on the rise, yet there are few systematic reviews investigating their experiences. Thus, this review classifies and synthesises qualitative research findings of studies published between 1990 to 2020 that have examined the needs and challenges of homeless older adults to elucidate their journey of homelessness. Seven papers met the requirements for inclusion. Three main themes were identified in the review: - (1) Pathways to homelessness, (2) Impact of homelessness, and (3) Outcomes and resolutions. This review collates current evidence on what is known about the experience of homelessness among older adults. In this study, homeless older adults identified a wide range of challenges associated with the experience of homelessness.

RESUMEN

BACKGROUND: Patients with Class III obesity pose unique challenges to health care staff and organisations. Care requirements of this population are unique and require specialised equipment and knowledge to meet these needs, maintain the quality of care, as well as the safety of patients and staff. AIM: To synthesise the evidence on the nursing care of Class III obese patients in acute care settings. METHODS: A scoping review informed by JBI. CINAHL Plus, Medline, Scopus, Proquest Central, Web of Science and Embase were searched for primary research articles about the nursing management of people classified as Class III obese in acute care. Methodological quality of included studies was assessed; data extracted and synthesised into themes. RESULTS: Fourteen studies were included in the review. The synthesis generated three themes: Access to equipment, knowledge and training, patient care, and opportunities to improve care. CONCLUSIONS: A paucity of high-quality evidence informs the nursing care of people with Class III obesity in acute care. Access to appropriate equipment dominated the findings of this review. Adequate provision of equipment and education on its use are required. Education to promote engagement with patients, adapting clinical practice and promotion of self-care could improve care and outcomes.
