Relationship between Composition and Environmental Degradation of Poly(isosorbide-co-diol oxalate) (PISOX) Copolyesters.

To reduce the global CO2 footprint of plastics, bio- and CO2-based feedstock are considered the most important design features for plastics. Oxalic acid from CO2 and isosorbide from biomass are interesting rigid building blocks for high Tg polyesters. The biodegradability of a family of novel fully renewable (bio- and CO2-based) poly(isosorbide-co-diol) oxalate (PISOX-diol) copolyesters was studied. We systematically investigated the effects of the composition on biodegradation at ambient temperature in soil for PISOX (co)polyesters. Results show that the lag phase of PISOX (co)polyester biodegradation varies from 0 to 7 weeks. All (co)polyesters undergo over 80% mineralization within 180 days (faster than the cellulose reference) except one composition with the cyclic codiol 1,4-cyclohexanedimethanol (CHDM). Their relatively fast degradability is independent of the type of noncyclic codiol and results from facile nonenzymatic hydrolysis of oxalate ester bonds (especially oxalate isosorbide bonds), which mostly hydrolyzed completely within 180 days. On the other hand, partially replacing oxalate with terephthalate units enhances the polymer's resistance to hydrolysis and its biodegradability in soil. Our study demonstrates the potential for tuning PISOX copolyester structures to design biodegradable plastics with improved thermal, mechanical, and barrier properties.

Ethnic variation in access to publicly funded care for unintentional injuries in older adults in Aotearoa New Zealand: a retrospective study.

BACKGROUND: Maori (the Indigenous people of Aotearoa New Zealand (NZ)) are more likely to experience injury than non-Maori, but less likely to have effective access to publicly funded injury care services. It is unknown if this pattern extends into older age. This retrospective study analysed Accident Compensation Corporation (ACC; national no-fault injury compensation scheme) claims data to investigate ethnic variation in unintentional injury claims and related costs for older adults (≥50 years). METHODS: Injury claims data for older adults residing in two regions of NZ between January 2014 and December 2018 were reviewed. Age-standardised claims rates (per person year) standardised rate ratios were calculated and compared between Maori and non-Maori. ACC claim costs (medical treatment; earning-related compensation) were estimated, with total and average costs per claim compared between the two groups. RESULTS: There were 149 275 ACC claims (18 369 Maori; 130 906 non-Maori) among 64 238 individuals (9284 Maori; 54 954 non-Maori). The age-standardised rate of ACC claims for unintentional injury was 46% higher among non-Maori (95% CI 44% to 48%) than Maori. The ACC spend for non-Maori was NZ$155 277 962 compared with NZ$30 446 673 for Maori. Maori had a significantly higher average cost per claim (NZ$1658 vs NZ$1186, p<0.001). CONCLUSIONS: Results of this study highlight differences in the manner in which different groups of older adults access injury compensation in NZ, indicating the need to invest in injury prevention initiatives that target older Maori, as well as initiatives supporting improved ACC access for older Maori.

Rural unpaid caregivers' experiences in northern Aotearoa, New Zealand during the Covid-19 pandemic: A qualitative study.

OBJECTIVE: Rural unpaid caregivers experience different opportunities and challenges than their urban counterparts. Our aim was to understand rural unpaid caregivers' experiences of challenges and opportunities during the Covid-19 pandemic in New Zealand. SETTING: Rural northern New Zealand during the Covid-19 pandemic. PARTICIPANTS: A convenience sample of 10 unpaid rural caregivers, most supporting an older person living with dementia. DESIGN: A qualitative descriptive design. Data included interviews and online workshops, and a thematic analysis. RESULTS: Rural unpaid caregivers observed that some aspects of living in a rural context were helpful during the Covid-19 pandemic. However, tasks such as shopping and long-distance travel and communication (both telephonic and digital) became more complex. Abrupt changes to routine and closure of resources and support groups created challenges. Unpaid caregivers worried about what would happen if they were hospitalised themselves. There was a diversity of experience both across caregivers, of familiar routines and rural context as resources, increased challenges requiring resourcefulness to adapt, and experiences of crisis. Many experienced all three states at different times. CONCLUSION: This research provides valuable insights into challenges and opportunities experienced by rural unpaid caregivers during the Covid-19 pandemic and may help policy-makers and healthcare professionals develop improved emergency preparedness. Multilevel, multisector responses are needed to ensure effective health and social support and access to resources including health care, access to groceries and medication, transport, and communications (telephone and digital). Enhancing rural access to effective and inexpensive online services is particularly important, as is recognition of the value of rural sites or hubs of connection and social interaction.

"It's all about the money": an interpretive description of embedding physical therapy-led falls prevention group exercise in long-term care.

BACKGROUND: Falls prevention interventions are effective for community dwelling older adults however, the same cannot be said for older adults living in long-term care (LTC). The Staying UpRight (SUp) randomized controlled trial was designed to test the effectiveness of a progressive strength and balance group exercise program delivered to LTC residents. This paper explores the factors impacting LTC providers' decisions to continue the program on completion of the funded trial period. METHODS: A qualitative study using an Interpretive Description approach. Semi-structured interviews and focus groups were conducted with 15 LTC staff involved in the randomized controlled trial. Data were analysed using conventional content analysis. RESULTS: Practice change occurred following participation in the trial with some facilities starting exercise groups, some increasing the number of exercise groups offered and physical therapists selecting elements of the program to adopt into their practice. Decisions about continuing with SUp as designed were constrained by organizational decisions regarding funding and resources. Three factors were identified which informed decision-making: business models and philosophies, requirements for evidence, and valuing physical therapy. CONCLUSIONS: Managers and facilitators adapted SUp by selecting and delivering components of the program in response to the changes they had observed in participating residents. However, our findings highlight that while SUp was valued, the tight financial environment created by the current funding model in New Zealand did not support funding physical therapist delivered falls prevention exercise programs in LTC. This study may provide policy makers with important information on changes needed to support falls prevention service delivery in LTC. TRIAL REGISTRATION: This study is a sub-study of a randomized controlled trial which was registered to the Australian New Zealand Clinical Trials Registry ACTRN12618001827224 on 09/11/2018. Universal trial number U1111-1217-7148.

"Embracing The Faith": The Contribution of Islamic Beliefs on the Provision of Care for People with Parkinson's Disease in New Zealand and Indonesia.

This study examines the impact of Islamic beliefs on the caregiving practices of individuals diagnosed with Parkinson's disease in Indonesia and New Zealand. The study sample comprised seventeen caregivers who participated in semi-structured interviews which were analysed using the method of inductive thematic analysis. The study delineated three overarching themes: value-driven caregiving, comprehensive care and caregivers strengthened by faith and practice. This study examined the practical applications of the Quran, Hadith and Muslim beliefs in caregiver experiences. Further research is necessary to enhance the support systems for Muslim caregivers in various circumstances, facilitating the advancement of solutions to contemporary social problems.

Feasibility and acceptability of a paearahi (Indigenous Whanau Ora navigator) intervention for unintentional injury prevention for older Maori: non-randomised, non-comparator trial study protocol.

BACKGROUND: Maori (the Indigenous population of Aotearoa New Zealand) experience increased burden of unintentional injury and reduced access to publicly funded injury prevention and rehabilitation services, compared with non-Maori. Maori-led models of care have been shown to improve outcomes for Maori. Paearahi navigate across sectors (including health, education, housing and employment) to advocate for the best possible outcomes for individuals and families. This study aims to (1) test the acceptability and feasibility and (2) undertake exploratory efficacy analysis of a paearahi injury intervention for Maori older adults. METHODS: A prospective non-randomised, non-comparator study with preintervention and postintervention measurements of predefined outcomes. Eligible participants who consented to participate (Maori, 55+ years, community-dwelling and enrolled in one of three study general practices) will undergo a multivisit paearahi intervention. The intervention includes home-hazard assessment, basic health screening, teaching of strength and balance exercises, education relating to injury prevention and access to injury-related, referral and connection to other health and social services) and participants can choose to have whanau (family) involved in the intervention. OUTCOMES: The primary outcome of interest is participant, whanau and paearahi acceptability of the intervention. Secondary outcomes include intervention feasibility, cost-effectiveness and exploratory efficacy (including preintervention and postintervention unintentional injury-related hospitalisation, primary care access and public injury-related claims). DISCUSSION: The findings of this intervention research will be used to inform injury care models for older Maori and process for Maori-led health intervention development more generally. TRIAL REGISTRATION NUMBER: ACTRN12621001691831p.

Effects of cognitive interventions on quality of life among adults with mild cognitive impairment: A systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: There is considerable research exploring the impact of cognitive interventions on cognition in people with mild cognitive impairment (MCI). However, the impact on quality of life (QOL) is not routinely reported. As QOL is a key predictor of health outcomes, it is important to determine the evidence supporting cognitive interventions for improving QOL in people with MCI. OBJECTIVE: To evaluate the evidence on the effectiveness of cognitive interventions for improving QOL among people with MCI. DESIGN: Systematic review and meta-analysis. METHODS: A systematic database search was conducted from inception to December 11, 2021, using four databases. Quality assessment was conducted, and data on the characteristics of the studies and the effects on QOL were extracted. Subgroup analyses and meta-regression were conducted to elucidate the effects of potential moderator variables on QOL measures. RESULTS: Of the 1550 records initially identified, 17 studies met the criteria for the final meta-analysis. The findings revealed that cognitive interventions produced moderate gains in overall QOL compared to the control group at the posttest (standardized mean difference (SMD): 0.53, 95% confidence interval (CI): [0.23, 0.84]), but no statistically significant differences were found at the end of follow-up (SMD: 0.40, 95% CI: [-0.15,0.94]). Furthermore, the effects of cognitive interventions were moderated by intervention duration, session duration, and study location. However, intervention types, session frequency, intervention components, control condition, total number of sessions, types of QOL measures, and responders to QOL-AD had no statistically significant effects on QOL outcome. CONCLUSIONS: Cognitive interventions have positive effects on QOL among adults with MCI. However, the high heterogeneity of the included studies calls for more well-designed cognitive intervention trials to examine the association between QOL and relevant moderators.

Oral Care in Hospital Settings: Breaking the Vicious Circle of Older Adult Deconditioning.

Hospitalized older adults frequently develop aspiration pneumonia, swallowing dys-function (dysphagia), and sarcopenia. In the current study, we propose a framework that incorporates these three factors into a vicious circle that leads to deconditioning, a condition frequently experienced by this vulnerable population. Viewing aspiration pneumonia, dysphagia, and sarcopenia, along with their interrelationships through the lens of this vicious circle, illuminates the critical role that oral health plays in deconditioning. Moreover, this framework highlights oral care as a key nursing intervention for reducing deconditioning in hospitalized older adults. Supporting this view, several studies have shown that oral care can improve health outcomes for hospitalized older adults. However, despite oral care being an essential nursing intervention that restores oral function and promotes patient wellness, it is one of the most neglected nursing interventions. Missed oral care occurs due to staff's limited awareness of its significance for care-dependent older adults in hospital settings. We hope that this vicious circle paradigm helps raise awareness of the significance of oral care to prevent deconditioning in hospitalized older adults.

Pilot-scale hybrid constructed wetlands for the treatment of cooling tower water prior to its desalination and reuse.

Cooling towers are responsible for a large part of the industrial fresh water withdrawal, and the reuse of cooling tower water (CTW) effluents can strongly lower industrial fresh water footprints. CTW requires desalination prior to being reused, but various CTW components, such as total organic carbon (TOC), conditioning chemicals and total suspended solids (TSS) hamper physico-chemical desalination technologies and need to be removed from the CTW. A cost-efficient and robust pre-treatment is thus required, which can be provided by constructed wetlands (CWs). The present study is the first study that determined the CTW pre-treatment efficiency of hybrid-CWs and the impact of winter season and biocides in the CTW on the pre-treatment efficiency. The most efficient CW flow type and dominant removal mechanisms for CW components hampering physico-chemical desalination were determined. Subsurface flow CWs removed PO43-, TSS and TOC as a result of adsorption and filtration. Vertical subsurface flow CWs (VSSF-CW) excelled in the removal of benzotriazole as a result of aerobic biodegradation. Horizontal subsurface flow CWs (HSSF-CW) allowed the denitrification of NO3- due to their anaerobic conditions. Open water CWs (OW-CWs) did not contribute to the removal of components that hamper physico-chemical desalination technologies, but do provide water storage options and habitat. The biological removal processes in the different CW flow types were negatively impacted by the winter season, but were not impacted by concentrations of the biocides glutaraldehyde and DBNPA that are relevant in practice. For optimal pre-treatment, a hybrid-CW, consisting of an initial VSSF-CW followed by an OW-CW and HSSF-CW is recommended. Future research should focus on integrating the hybrid-CW with a desalination technology, e.g. reverse osmosis, electrodialysis or capacitive ionization, to produce water that meets the requirements for use as cooling water and allow the reuse of CTW in the cooling tower itself.

A Nondestructive Method to Identify POP Contamination Sources in Omnivorous Seabirds.

Persistent organic pollutants (POPs) are present in almost all environments due to their high bioaccumulation potential. Especially species that adapted to human activities, like gulls, might be exposed to harmful concentrations of these chemicals. The nature and degree of the exposure to POPs greatly vary between individual gulls, due to their diverse foraging behavior and specialization in certain foraging tactics. Therefore, in order clarify the effect of POP-contaminated areas on gull populations, it is important to identify the sources of POP contamination in individual gulls. Conventional sampling methods applied when studying POP contamination are destructive and ethically undesired. The aim of this literature review was to evaluate the potential of using feathers as a nondestructive method to determine sources of POP contamination in individual gulls. The reviewed data showed that high concentrations of PCBs and PBDEs in feathers together with a large proportion of less bioaccumulative congeners may indicate that the contamination originates from landfills. Low PCB and PBDE concentrations in feathers and a large proportion of more bioaccumulative congeners could indicate that the contamination originates from marine prey. We propose a nondestructive approach to identify the source of contamination in individual gulls based on individual contamination levels and PCB and PBDE congener profiles in feathers. Despite some uncertainties that might be reduced by future research, we conclude that especially when integrated with other methods like GPS tracking and the analysis of stable isotopic signatures, identifying the source of POP contamination based on congener profiles in feathers could become a powerful nondestructive method.

Biodegradation of metformin and its transformation product, guanylurea, by natural and exposed microbial communities.

Metformin (MET) is a pharmaceutical product mostly biotransformed in the environment to a transformation product, guanylurea (GUA). In ready biodegradability tests (RBTs), however, contrasting results have been observed for metformin. The objective of this study was to measure the biodegradation of MET and GUA in RBTs, using activated sludge from the local wastewater treatment plant, either directly or after pre-exposure to MET, in a chemostat. The activated sludge community was cultivated in chemostats, in presence or absence of MET, for a period of nine months, and was used in RBT after one, three and nine months. The results of this study showed that the original activated sludge was able to completely remove MET (15 mg/l) and the newly produced GUA (50% of C0MET) under the test conditions. Inoculation of the chemostat led to a rapid shift in the community composition and abundance. The community exposed to 1.5 mg/l of MET was still able to completely consume MET in the RBTs after one-month exposure, but three- and nine-months exposure resulted in reduced removal of MET in the RBTs. The ability of the activated sludge community to degrade MET and GUA is the result of environmental exposure to these chemicals as well as of conditions that could not be reproduced in the laboratory system. A MET-degrading strain belonging to the genus Aminobacter has been isolated from the chemostat community. This strain was able to completely consume 15 mg/l of MET within three days in the test. However, community analysis revealed that the fluctuation in relative abundance of this genus (<1%) could not be correlated to the fluctuation in biodegradation capacity of the chemostat community.

Supported Discharge Teams for older people in hospital acute care: a randomised controlled trial.

Background: Supported Discharge Teams aim to help with the transition from hospital to home, whilst reducing hospital length-of-stay. Despite their obvious attraction, the evidence remains mixed, ranging from strong support for disease-specific interventions to less favourable results for generic services. Objective: To determine whether older people referred to a Supported Discharge Team have: (i) reduced length-of-stay in hospital; (ii) reduced risk of hospital readmission; and (iii) reduced healthcare costs. Methods: Randomised controlled trial with follow-up to 6 months; 103 older women and 80 men (n = 183) (mean age 79), in hospital, were randomised to receive either Supported Discharge Team or usual care. Home-based rehabilitation was delivered by trained Health Care Assistants up to four times a day, 7 days a week, under the guidance of registered nurses, allied health and geriatricians for up to 6 weeks. Results: Participants randomised to the Supported Discharge Team spent less time in hospital during the index admission (mean 15.7 days) in comparison to usual care (mean 21.6 days) (mean difference 5.9: 95% CI 0.6, 11.3 days: P = 0.03) and spent less time in hospital in the 6 months following discharge home. Supported discharge group costs were calculated at mean NZ$10,836 (SD NZ$12,087) compared to NZ$16,943 (SD NZ$22,303) in usual care. Conclusion: A Supported Discharge Team can provide an effective means of discharging older people home early from hospital and can make a cost-effective contribution to managing increasing demand for hospital beds.

"You've got to look after yourself, to be able to look after them" a qualitative study of the unmet needs of caregivers of community based primary health care patients.

BACKGROUND: There is growing reliance on unpaid caregivers to provide support to people with care needs. Integrated care approaches that aim to coordinate primary care with community care known as community based primary health care (CBPHC) has been a key policy initiative across health systems; however most attention has been paid to the needs of patients and not caregivers. The objective of this paper was to explore the unmet needs of caregivers of older adults with complex care needs receiving CBPHC. METHODS: This qualitative descriptive study entailed one-to-one interviews with 80 caregivers from Canada and New Zealand where roles, experiences and needs were explored. Interview text related to unmet need was reviewed inductively and core themes identified. RESULTS: Three themes were identified across CBPHC sites: unrecognized role; lack of personal resources; and no breaks even when services are in place. CONCLUSIONS: To support caregivers, models of care such as CBPHC need to look beyond the patient to meaningfully engage caregivers, address their needs and recognize the insight they hold. This knowledge needs to be valued as a key source of evidence to inform developments in health and social care.

Implementation of the 2017 Berlin Concussion in Sport Group Consensus Statement in contact and collision sports: a joint position statement from 11 national and international sports organisations.

The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement's themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities. This document summarises the approaches discussed by medical representatives from the governing bodies of 10 different contact and collision sports in Dublin, Ireland in July 2017. Those sports are: American football, Australian football, basketball, cricket, equestrian sports, football/soccer, ice hockey, rugby league, rugby union and skiing. This document had been endorsed by 11 sport governing bodies/national federations at the time of being published.

Older people's experiences of nurse-patient telephone communication in the primary healthcare setting.

AIM: To determine which aspects of primary nurse-patient telephone communication are viewed positively or negatively in terms of meeting the older persons' needs. BACKGROUND: Health professionals are increasingly being called on to develop different ways of working and increase their capacity to meet the needs of an ageing population. In some countries, telephone communication between primary nurses and patients in General Practice is already seen as a routine practice, but determining the value of this type of communication as a specific health service needs more understanding. DESIGN: A qualitative exploratory study as the aim was to explore the older person's experiences. METHODS: Semi-structured interviews were conducted with 21 older people from General Practices in New Zealand during 2014-2015. Thematic analysis was informed by a constructivist grounded theory approach. FINDINGS: The overarching theme was the difficulties older people face in making decisions about whether to contact a health professional by telephone and whether this should be the Primary nurse. Accounting for some of their symptoms as age related added to the uncertainty of decision-making. Importantly, some older people were not raising concerns e.g. emotional state. CONCLUSION: Decision-making by older people around treatment seeking is complex. Increasing the awareness of the nurse role in the General Practice is integral to creating a health system which will meet the needs of a growing older population. Primary care practices can review their systems to better inform older people how the nurse-telephone role as a specific health service works and what they can expect when using this service.

Identification of Novel Brominated Compounds in Flame Retarded Plastics Containing TBBPA by Combining Isotope Pattern and Mass Defect Cluster Analysis.

The study of not only main flame retardants but also of related degradation products or impurities has gained attention in the last years and is relevant to assess the safety of our consumer products and the emission of potential contaminants into the environment. In this study, we show that plastics casings of electric/electronic devices containing TBBPA contain also a complex mixture of related brominated chemicals. These compounds were most probably coming from impurities, byproducts, or degradation products of TBBPA and TBBPA derivatives. A total of 14 brominated compounds were identified based on accurate mass measurements (formulas and tentative structures proposed). The formulas (or number of bromine elements) for 19 other brominated compounds of minor intensity are also provided. A new script for the recognition of halogenated compounds based on combining a simplified isotope pattern and mass defect cluster analysis was developed in R for the screening. The identified compounds could be relevant from an environmental and industrial point of view.

Modelling the Release, Transport and Fate of Engineered Nanoparticles in the Aquatic Environment - A Review.

Engineered nanoparticles, that is, particles of up to 100 nm in at least one dimension, are used in many consumer products. Their release into the environment as a consequence of their production and use has raised concern about the possible consequences. While they are made of ordinary substances, their size gives them properties that are not manifest in larger particles. It is precisely these properties that make them useful. For instance titanium dioxide nanoparticles are used in transparent sunscreens, because they are large enough to scatter ultraviolet light but too small to scatter visible light.To investigate the occurrence of nanoparticles in the environment we require practical methods to detect their presence and to measure the concentrations as well as adequate modelling techniques. Modelling provides both a complement to the available detection and measurement methods and the means to understand and predict the release, transport and fate of nanoparticles. Many different modelling approaches have been developed, but it is not always clear for what questions regarding nanoparticles in the environment these approaches can be applied. No modelling technique can be used for every possible aspect of the release of nanoparticles into the environment. Hence it is important to understand which technique to apply in what situation. This article provides an overview of the techniques involved with their strengths and weaknesses. Two points need to be stressed here: the modelling of processes like dissolution and the surface activity of nanoparticles, possibly under influence of ultraviolet light, or chemical transformation has so far received relatively little attention. But also the uncertainties surrounding nanoparticles in general-the amount of nanoparticles used in consumer products, what constitutes the appropriate measure of concentration (mass or numbers) and what processes are relevant-should be explicitly considered as part of the modelling.

Concussion Knowledge and Communication Behaviors of Collegiate Wrestling Coaches.

Sport coaches can play an important role in shaping a team's approach to concussion safety through their communication with team members. However, across all sports, there is limited knowledge about factors that make coaches more or less likely to engage in safety-supportive communication. The objectives of this study were to assess the concussion-related knowledge and attitudes of wrestling coaches, as well as the extent to which they engage in autonomy-supportive coaching practices, and to determine how these factors are related to communication with athletes in support of concussion safety. Data were collected through an online survey of head coaches of National Collegiate Athletic Association (NCAA) wrestling teams (n = 89, 40.5% response rate). On average, coaches answered five out of a possible nine knowledge questions correctly and were significantly more likely to think it was acceptable for an athlete to continue playing after sustaining a concussion during a national qualifying competition as compared to during an early-season competition. Engaging in autonomy-supportive coaching behaviors was the coach factor explaining the largest percentage of variability in communication. Findings suggest that while knowledge deficits and attitudes about the acceptability of continued play while symptomatic during more consequential competitive matches should be addressed in educational programming for collegiate wrestling coaches, these changes alone may not be a sufficient for adequately increasing concussion safety communication. Targeting more distal factors such as autonomy-supportive approaches to coaching may hold promise for intervention design and should be explored in future prospective research.
