Co-design of a personalised digital intervention to improve vegetable intake in adults living in Australian rural communities

\ua9 2024, The Author(s). Background: Diets low in vegetables are a main contributor to the health burden experienced by Australians living in rural communities. Given the ubiquity of smartphones and access to the Internet, digital interventions may offer an accessible delivery model for a dietary intervention in rural communities. However, no digital interventions to address low vegetable intake have been co-designed with adults living in rural areas. This paper describes the co-design of a digital intervention to improve vegetable intake with rural community members and research partners. Methods: Active participants in the co-design process were adults ≥ 18 years living in three rural Australian communities (total n = 57) and research partners (n = 4) representing three local rural governments and one peak non-government health organisation. An iterative co-design process was undertaken to understand the needs (pre-design phase) and ideas (generative phase) of the target population. Eight online workshops and a community survey were conducted between July and December 2021. The MoSCoW prioritisation method was used to help participants identify the ‘Must-have, Should-have, Could-have, and Won’t-have or will not have right now’ features and functions of the digital intervention. Workshops were transcribed and inductively analysed using NVivo. Convergent and divergent themes were identified between the workshops and community survey to identify how to implement the digital intervention in the community. Results: Consensus was reached on a concept for a digital intervention that addressed individual and food environment barriers to vegetable intake, specific to rural communities. Implementation recommendations centred on (i) food literacy approaches to improve skills via access to vegetable-rich recipes and healthy eating resources, (ii) access to personalisation options and behaviour change support, and (iii) improving the community food environment by providing information on and access to local food initiatives. Conclusions: Rural-dwelling adults expressed preferences for personalised intervention features that can enhance food literacy and engagement with community food environments. This research will inform the development of the prototyping (evaluation phase) and feasibility testing (post-design phase) of this intervention

An observational cohort study of exercise and education for people with chronic obstructive pulmonary disease not meeting criteria for formal pulmonary rehabilitation programmes

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Pulmonary rehabilitation (PR) is offered to patients with functional breathlessness. However, access to PR is limited. The objective of this study was to evaluate whether a 4-week education and exercise programme offered to COPD patients with Medical Research Council (MRC) dyspnoea 1–2 improves disease self-management. Patients were recruited by their GP to attend four weekly 2-h sessions provided by a multidisciplinary team. Patients completed outcome measures before and after the program. Forty-two patients entered the programme and 26 out of 42 (61.9%) completed all sessions. The Bristol COPD Knowledge Questionnaire and Patient Activation Measure improved (both p ≤ 0.001). Disease burden was not reduced according to the COPD assessment test. All patients accepted a referral for ongoing exercise. Fourteen current smokers (81.3%) accepted a referral for smoking cessation, three patients with anxiety or depression (37.5%) accepted a psychological therapies referral. The programme improved COPD disease knowledge, patient activation and stimulated referrals to further services supporting disease management. Randomised controlled trials are warranted for similar interventions for COPD patients with early stage disease

MycoRRdb: A Database of Computationally Identified Regulatory Regions within Intergenic Sequences in Mycobacterial Genomes

The identification of regulatory regions for a gene is an important step towards deciphering the gene regulation. Regulatory regions tend to be conserved under evolution that facilitates the application of comparative genomics to identify such regions. The present study is an attempt to make use of this attribute to identify regulatory regions in the Mycobacterium species followed by the development of a database, MycoRRdb. It consist the regulatory regions identified within the intergenic distances of 25 mycobacterial species. MycoRRdb allows to retrieve the identified intergenic regulatory elements in the mycobacterial genomes. In addition to the predicted motifs, it also allows user to retrieve the Reciprocal Best BLAST Hits across the mycobacterial genomes. It is a useful resource to understand the transcriptional regulatory mechanism of mycobacterial species. This database is first of its kind which specifically addresses cis-regulatory regions and also comprehensive to the mycobacterial species. Database URL: http://mycorrdb.uohbif.in

Contrasting Transcriptional Responses of a Virulent and an Attenuated Strain of Mycobacterium tuberculosis Infecting Macrophages

Along with the recent identification of single nucleotide polymorphisms in H37Ra when compared to H37Rv, our demonstration of differential expression of PhoP-regulated and ESX-1 region-related genes during macrophage infection further highlights the significance of these genes in the attenuation of H37Ra

Cellular studies of an aminoglycoside potentiator reveal a new inhibitor of aminoglycoside resistance

Aminoglycosides are a group of broad‐spectrum antibiotics that have been used in the clinic for almost a century. The rapid spread of bacterial genes coding for aminoglycoside‐modifying enzymes has, however, dramatically decreased the utility of aminoglycosides. We have previously reported several aminoglycoside potentiators that work by inhibiting aminoglycoside N‐6′‐acetyltransferase, one of the most common determinants of aminoglycoside resistance. Among these, prodrugs that combine the structure of an aminoglycoside with that of pantothenate into one molecule are especially promising. We report here a series of cellular studies to investigate the activity and mechanism of action of these prodrugs further. Our results reveal a new aminoglycoside resistance inhibitor, as well as the possibility that these prodrugs are transformed into more than one inhibitor in bacteria. We also report that the onset of the potentiators is rapid. Their low cell cytotoxicity, good stability, and potentiation of various aminoglycosides, against both Gram‐positive and Gram‐negative bacteria, make them interesting compounds for the development of new drugs

INTRODUCTION: Diets low in vegetables are a main contributor to the health burden experienced by young adults in rural communities. Digital health interventions provide an accessible delivery model that can be personalised to meet the diverse preferences of young adults. A personalisable digital vegetable intake intervention (Veg4Me) was codesigned to meet the needs of young adults living in rural communities. This study will determine the feasibility of delivering a personalised Veg4Me programme and compare preliminary effects with a non-personalised Veg4Me (control). METHODS AND ANALYSIS: A 12-week assessor-blinded, two-arm, parallel randomised controlled trial will be undertaken from August 2023 until April 2024. A total of 150 eligible and consenting young adults (18-35 years; eat<5 serves of vegetables/day; have an internet connected mobile device/computer) living in Loddon Campaspe or Colac Otway Shire in Victoria, Australia, will be randomised to receive 12 weeks of personalised (intervention) or non-personalised (control) support to increase vegetable intake via a free web application (app; Veg4Me). The primary outcome is feasibility (recruitment, participation and retention rates). Secondary outcomes are user engagement, usability and experience, as well as vegetable intake, eating habits and digital health equity. Process evaluation will be conducted in a subsample of participants using semistructured interviews. Descriptive statistics will be presented for the personalised and non-personalised groups at baseline and 12 weeks. Generalised linear models will be used to evaluate group differences in outcomes. Interviews will be transcribed and analysed thematically. ETHICS AND DISSEMINATION: All procedures involving human subjects were approved by Deakin University\u27s Human Ethics Advisory Group-Health (HEAG-H 06_2023) on 6 March 2023. Dissemination events will be held in the City of Greater Bendigo and the Colac Otway Shire. Summaries of the results will be disseminated to participants via email. Results will be disseminated to the scientific community through peer-reviewed publications and conference presentations.
