Maintaining the health of people with and without COVID-19 during isolation: a case study.

This case study evaluated the effects of a health package (HP) of a light intensity individualised exercise program and advice on anxiety management and nutrition, on the physical and mental health of people with or without COVID-19, who were quarantined in hotels used as Special Health Accommodation and admitted to the Royal Prince Alfred Virtual Hospital, Sydney during the COVID-19 pandemic. After initial screening and consenting, participants completed three surveys: Depression, Anxiety, Stress Scale; Brief Fatigue Inventory; and the European Quality of Life 5-Dimensions 5-Levels, and were provided with the HP for the duration of their quarantine. The three surveys and a participant reported experience measure were completed prior to discharge. The HP for people in quarantine demonstrated stability of health outcomes and reduction in fatigue. Most participants reported that the HP helped them cope with isolation. Provision of a HP during quarantine could be useful to support physical and mental health.

Promoting community stakeholder engagement in research on treatment for pregnant women with opioid use disorder.

Aim: Community stakeholder engagement in research (CSER) can improve research relevance and efficiency as well as prevent harmful practices, particularly for vulnerable populations. Despite potential benefits, researchers lack familiarity with CSER methods. Methods: We describe CSER strategies used across the research continuum, including proposal development, study planning and the first years of a comparative effectiveness study of care for pregnant women with opioid use disorder. Results: We highlight successful strategies, grounded in principles of engagement, to establish and maintain stakeholder relationships, foster bidirectional communication and trust and support active participation of women with opioid use disorder in the research process. Conclusion: CSER methods support research with a disenfranchised population. Future work will evaluate the impact of CSER strategies on study outcomes and dissemination.

Community stakeholder engagement in research on treatment for pregnant women with opioid use disorder builds and maintains stakeholder relationships, fosters communication and trust and supports active patient participation.

"It Takes Some Empathy, Sympathy, and Listening": Telephone Outreach to Older Detroiters in a Pandemic as a Modality to Gain an Understanding of Challenges and Resiliency.

This manuscript describes a telephone outreach project for members of a research registry program for older adults in Detroit, Michigan. From April until December 2020, the Healthier Black Elders Center designed and implemented a telephone outreach program, calling 1204 older adults utilizing 15 staff and volunteers. The calls served to check in on registry members and collect data on mental health, coping mechanisms, access to services, masks, testing, and tele-health. This paper details the methods of developing and implementing an innovative engagement program that collected time-sensitive data from older Black adults that has directly been applied to create virtual health education programs, share resource information, and create a program to reduce social isolation.

Creation and validation of 3D-printed head molds for stereotaxic injections of neonatal mouse brains.

BACKGROUND: An increasing number of rodent model systems use injection of DNA or viral constructs in the neonatal brain. However, approaches for reliable positioning and stereotaxic injection at this developmental stage are limited, typically relying on handheld positioning or molds that must be re-aligned for use in a given laboratory. NEW METHOD: A complete protocol and open-source software pipeline for generating 3D-printed head molds derived from a CT scan of a neonatal mouse head cast, together with a universal adapter that can be placed on a standard stereotaxic stage. RESULTS: A series of test injections with adenovirus encoding red fluorescent protein, or Fluorogold, were conducted using original clay molds and newly generated 3D printed molds. Several metrics were used to compare spread and localization of targeted injections. COMPARISON WITH EXISTING METHODS: The new method of head mold generation gave comparable results to the field standard, but also allowed the rapid generation of additional copies of each head mold with standardized positioning of the head each time. CONCLUSIONS: This 3D printing pipeline can be used to efficiently develop a series of head molds with standardized injection coordinates across multiple laboratories. More broadly, this pipeline can easily be adapted to other perinatal ages or species.

Understanding the use and impact of allied health services for people with chronic health conditions in Central and Eastern Sydney, Australia: a five-year longitudinal analysis.

AIM: To describe the characteristics of people in Central and Eastern Sydney (CES), NSW, who had a General Practice Management Plan (GPMP) and claimed for at least one private allied health service item; and to examine if allied health service use results in less hospitalisations over a five-year period. BACKGROUND: The number of people living with chronic health conditions is increasing in Australia. The Chronic Disease Management programme was introduced to the Medicare Benefits Schedule (MBS) to provide a more structured approach to managing patients with chronic conditions and complex care needs. The programme supports general practitioners claiming up to one GPMP and one Team Care Arrangement every year, and the patient additionally claiming for up to five private allied health services visits. METHODS: A prospective longitudinal study was conducted. The sample consisted of 5771 participants in CES who had a GPMP within a two-year health service utilisation baseline period (2007-2009). The analysis used the 45 and Up Study questionnaire data linked to the MBS, hospitalisation, death and emergency department data for the period 2006-2014. FINDINGS: Of the eligible participants, 43% (2460) had at least one allied health service item claim in the subsequent 12 months. Allied health services were reported as physiotherapy, podiatry and other allied health services. The highest rates of allied health service use were among participants aged 85 years and over (49%). After controlling for confounding factors, a significant difference was found between having claimed for five or more physiotherapy services and emergency admissions (HR: 0.83; 95% CI: 0.72-0.95) and potentially preventable hospitalisations (HR: 0.79; 95% CI: 0.64-0.96) in the subsequent five years. Use of allied health service items was well targeted towards those with chronic and complex care needs, and use of physiotherapy services was associated with less avoidable hospitalisations.

Effects of structural variation in xyloglucan polymers on interactions with bacterial cellulose.

A cellulose/xyloglucan framework is considered to form the basis for the mechanical properties of primary plant cell walls and hence to have a major influence on the biomechanical properties of growing, fleshy plant tissues. In this study, structural variants of xyloglucan have been investigated as components of composites with bacterial cellulose as a simplified model for the cellulose/xyloglucan framework of primary plant cell walls. Evidence for molecular binding to cellulose with perturbation of cellulose crystallinity was found for all xyloglucan types. High molecular mass samples gave homogeneous centimeter-scale composites with extensive cross-linking of cellulose with xyloglucan. Lower molecular mass xyloglucans gave heterogeneous composites having a range of microscopic structures with little, if any, cross-linking. Xyloglucans with reduced levels of galactose substitution had evidence of self-association, competitive with cellulose binding. At comparable molecular mass, fucose substitution resulted in a modest promotion of microscopic features characteristic of primary cell walls. Taken together, the data are evidence that galactose substitution of the xyloglucan core structure is a major determinant of cellulose composite formation and properties, with additional fucose substitution acting as a secondary modulator. These conclusions are consistent with reported structural and mechanical properties of Arabidopsis mutants lacking specific fucose and/or galactose residues.
