Wheat stripe rust resistance locus YR63 is a hot spot for evolution of defence genes - a pangenome discovery.

BACKGROUND: Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), poses a threat to global wheat production. Deployment of widely effective resistance genes underpins management of this ongoing threat. This study focused on the mapping of stripe rust resistance gene YR63 from a Portuguese hexaploid wheat landrace AUS27955 of the Watkins Collection. RESULTS: YR63 exhibits resistance to a broad spectrum of Pst races from Australia, Africa, Asia, Europe, Middle East and South America. It was mapped to the short arm of chromosome 7B, between two single nucleotide polymorphic (SNP) markers sunCS_YR63 and sunCS_67, positioned at 0.8 and 3.7 Mb, respectively, in the Chinese Spring genome assembly v2.1. We characterised YR63 locus using an integrated approach engaging targeted genotyping-by-sequencing (tGBS), mutagenesis, resistance gene enrichment and sequencing (MutRenSeq), RNA sequencing (RNASeq) and comparative genomic analysis with tetraploid (Zavitan and Svevo) and hexaploid (Chinese Spring) wheat genome references and 10+ hexaploid wheat genomes. YR63 is positioned at a hot spot enriched with multiple nucleotide-binding and leucine rich repeat (NLR) and kinase domain encoding genes, known widely for defence against pests and diseases in plants and animals. Detection of YR63 within these gene clusters is not possible through short-read sequencing due to high homology between members. However, using the sequence of a NLR member we were successful in detecting a closely linked SNP marker for YR63 and validated on a panel of Australian bread wheat, durum and triticale cultivars. CONCLUSIONS: This study highlights YR63 as a valuable source for resistance against Pst in Australia and elsewhere. The closely linked SNP marker will facilitate rapid introgression of YR63 into elite cultivars through marker-assisted selection. The bottleneck of this study reinforces the necessity for a long-read sequencing such as PacBio or Oxford Nanopore based techniques for accurate detection of the underlying resistance gene when it is part of a large gene cluster.

Differences in urban and suburban/rural settings regarding care provision and barriers of cancer care for older adults during COVID-19.

PURPOSE: Care for older adults with cancer became more challenging during the COVID-19 pandemic, particularly in urban hotspots. This study examined the potential differences in healthcare providers' provision of as well as barriers to cancer care for older adults with cancer between urban and suburban/rural settings. METHODS: Members of the Advocacy Committee of the Cancer and Aging Research Group, with the Association of Community Cancer Centers, surveyed multidisciplinary healthcare providers responsible for the direct care of patients with cancer. Respondents were recruited through organizational listservs, email blasts, and social media messages. Descriptive statistics and chi-square tests were used. RESULTS: Complete data was available from 271 respondents (urban (n = 144), suburban/rural (n = 127)). Most respondents were social workers (42, 44%) or medical doctors/advanced practice providers (34, 13%) in urban and suburban/rural settings, respectively. Twenty-four percent and 32.4% of urban-based providers reported "strongly considering" treatment delays among adults aged 76-85 and > 85, respectively, compared to 13% and 15.4% of suburban/rural providers (Ps = 0.048, 0.013). More urban-based providers reported they were inclined to prioritize treatment for younger adults over older adults than suburban/rural providers (10.4% vs. 3.1%, p = 0.04) during the pandemic. The top concerns reported were similar between the groups and related to patient safety, treatment delays, personal safety, and healthcare provider mental health. CONCLUSION: These findings demonstrate location-based differences in providers' attitudes regarding care provision for older adults with cancer during the COVID-19 pandemic.

Health-Related Quality of Life in Older Adults with Colorectal Cancer.

PURPOSE OF REVIEW: Health-related quality of life (HRQoL) is a topic of great importance among older patients with cancer. Here we review the literature on HRQoL in older patients with colon and rectal cancer. RECENT FINDINGS: HRQoL in older cancer patients with colon and rectal cancer can be impacted by care delivery model, use of selected treatments (i.e., chemotherapy), and the trajectory of the patient after surgery for colorectal cancer (CRC). HRQoL is an important outcome for older cancer patients. Greater numbers of older patients are undergoing treatment for CRC and may experience wide variations in quality of life during and after treatment. Trials should be developed with HRQoL as a primary outcome, and interventions need to be developed to maintain or improve HRQoL in older patients with cancer.

Using Geriatric Assessment Strategies to Lead End-of-Life Care Discussions.

End-of-life discussions with geriatric oncology patients are a vital part of the comprehensive care of the senior adult patient. Developing a roadmap for these conversations can be challenging. Patients and caregivers may have expectations that are not concordant with what is reasonably achievable if the patient is frail. Measuring baseline cognition, nutritional status, and physical function and discussing goals of care are all essential pieces of information that can be obtained through a comprehensive geriatric assessment (CGA). Objective findings from the CGA can be crucial in developing end-of-life care plans that reflect both the patient's health status and personal values.

Supportive Care in Older Adults with Cancer: Across the Continuum.

Supportive care is an essential component of anticancer treatment regardless of age or treatment intent. As the number of older adults with cancer increases, and supportive care strategies enable more patients to undergo treatment, greater numbers of older patients will become cancer survivors. These patients may have lingering adverse effects from treatment and will need continued supportive care interventions. Older adults with cancer benefit from geriatric assessment (GA)-guided supportive care interventions. This can occur at any stage across the cancer treatment continuum. As a GA commonly uncovers issues potentially unrelated to anticancer treatment, it could be argued that the assessment is essentially a supportive care strategy. Key aspects of a GA include identification of comorbidities, assessing for polypharmacy, screening for cognitive impairment and delirium, assessing functional status, and screening for psychosocial issues. Treatment-related issues of particular importance in older adults include recognition of increased bone marrow toxicity, management of nausea and vomiting, identification of anemia, and prevention of neurotoxicity. The role of physical therapy and cancer rehabilitation as a supportive care strategy in older adults is important regardless of treatment stage or intent.

Promoting healthy eating, active play and sustainability consciousness in early childhood curricula, addressing the Ben10™ problem: a randomised control trial.

BACKGROUND: This paper details the research protocol for a study funded by the Australian Research Council. An integrated approach towards helping young children respond to the significant pressures of '360 degree marketing' on their food choices, levels of active play, and sustainability consciousness via the early childhood curriculum is lacking. The overall goal of this study is to evaluate the efficacy of curriculum interventions that educators design when using a pedagogical communication strategy on children's knowledge about healthy eating, active play and the sustainability consequences of their toy food and toy selections. METHODS/DESIGN: This cluster-randomised trial will be conducted with 300, 4 to 5 year-old children attending pre-school. Early childhood educators will develop a curriculum intervention using a pedagogical communication strategy that integrates content knowledge about healthy eating, active play and sustainability consciousness and deliver this to their pre-school class. Children will be interviewed about their knowledge of healthy eating, active play and the sustainability consequences of their food and toy selections. Parents will complete an Eating and Physical Activity Questionnaire rating their children's food preferences, digital media viewing and physical activity habits. All measures will be administered at baseline, the end of the intervention and 6 months post intervention. Informed consent will be obtained from all parents and the pre-school classes will be allocated randomly to the intervention or wait-list control group. DISCUSSION: This study is the first to utilise an integrated pedagogical communication strategy developed specifically for early childhood educators focusing on children's healthy eating, active play, and sustainability consciousness. The significance of the early childhood period, for young children's learning about healthy eating, active play and sustainability, is now unquestioned. The specific teaching and learning practices used by early childhood educators, as part of the intervention program, will incorporate a sociocultural perspective on learning; this perspective emphasises building on the play interests of children, that are experienced within the family and home context, as a basis for curriculum provision.

Promoting obesity prevention together with environmental sustainability.

There is mounting evidence that current food production, transport, land use and urban design negatively impact both climate change and obesity outcomes. Recommendations to prevent climate change provide an opportunity to improve environmental outcomes and alter our food and physical activity environments in favour of a 'healthier' energy balance. Hence, setting goals to achieve a more sustainable society offers a unique opportunity to reduce levels of obesity. In the case of children, this approach is supported with evidence that even from a young age they show emerging understandings of complex environmental issues and are capable of both internalizing positive environmental values and influencing their own environmental outcomes. Given young children's high levels of environmental awareness, it is easy to see how environmental sustainability messages may help educate and motivate children to make 'healthier' choices. The purpose of this paper is to highlight a new approach to tackling childhood obesity by tapping into existing social movements, such as environmental sustainability, in order to increase children's motivation for healthy eating and physical activity behaviours and thus foster more wholesome communities. We contend that a social marketing framework may be a particularly useful tool to foster behaviour change beneficial to both personal and environmental health by increasing perceived benefits and reducing perceived costs of behaviour change. Consequently, we propose a new framework which highlights suggested pathways for helping children initiate and sustain 'healthier' behaviours in order to inform future research and potentially childhood obesity intervention strategies.

Healthcare providers' attitudes towards delay in cancer treatment during COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic has created unprecedented obstacles leading to delays in treatment for older adults with cancer. Due to limited resources at the height of the pandemic, healthcare providers were constantly faced with ethical dilemmas regarding postponing or rescheduling care for their patients. MATERIALS AND METHODS: Two survey-based studies were conducted at different time-points during the pandemic looking at factors affecting oncology care providers' attitudes towards delay in treatment for older adults with cancer. Eligible participants were recruited by email sent through professional organizations' listservs, email blasts, and social media. Change in provider attitude over time was analyzed by comparing responses from the 2020 and 2021 surveys. Data analysis included descriptive statistics and chi-squares. RESULTS: In 2020, 17.5% of respondents were strongly considering/considering postponing cancer treatment for younger patients (age 30 and below), while 46.2% were considering delaying treatment for patients aged >85. These responses were in stark contrast to the results of the 2021 survey, where only 1.4% of respondents strongly considered postponing treatment for younger patients, and 13.5% for patients aged >85. DISCUSSION: All recommendations to postpone treatment for older adults with cancer must be made after mutual discussion with the patient. Throughout the COVID-19 pandemic, oncology care providers had to consider multiple factors while treating patients, frequently making most decisions without appropriate institutional support.

Physical separation of haplotypes in dikaryons allows benchmarking of phasing accuracy in Nanopore and HiFi assemblies with Hi-C data.

BACKGROUND: Most animals and plants have more than one set of chromosomes and package these haplotypes into a single nucleus within each cell. In contrast, many fungal species carry multiple haploid nuclei per cell. Rust fungi are such species with two nuclei (karyons) that contain a full set of haploid chromosomes each. The physical separation of haplotypes in dikaryons means that, unlike in diploids, Hi-C chromatin contacts between haplotypes are false-positive signals. RESULTS: We generate the first chromosome-scale, fully-phased assembly for the dikaryotic leaf rust fungus Puccinia triticina and compare Nanopore MinION and PacBio HiFi sequence-based assemblies. We show that false-positive Hi-C contacts between haplotypes are predominantly caused by phase switches rather than by collapsed regions or Hi-C read mis-mappings. We introduce a method for phasing of dikaryotic genomes into the two haplotypes using Hi-C contact graphs, including a phase switch correction step. In the HiFi assembly, relatively few phase switches occur, and these are predominantly located at haplotig boundaries and can be readily corrected. In contrast, phase switches are widespread throughout the Nanopore assembly. We show that haploid genome read coverage of 30-40 times using HiFi sequencing is required for phasing of the leaf rust genome, with 0.7% heterozygosity, and that HiFi sequencing resolves genomic regions with low heterozygosity that are otherwise collapsed in the Nanopore assembly. CONCLUSIONS: This first Hi-C based phasing pipeline for dikaryons and comparison of long-read sequencing technologies will inform future genome assembly and haplotype phasing projects in other non-haploid organisms.

Screening and social prescribing in healthcare and social services to address housing issues among children and families: a systematic review.

OBJECTIVES: Housing is a social determinant of health that impacts the health and well-being of children and families. Screening and referral to address social determinants of health in clinical and social service settings has been proposed to support families with housing problems. This study aims to identify housing screening questions asked of families in healthcare and social services, determine validated screening tools and extract information about recommendations for action after screening for housing issues. METHODS: The electronic databases MEDLINE, PsycINFO, EMBASE, Ovid Emcare, Scopus and CINAHL were searched from 2009 to 2021. Inclusion criteria were peer-reviewed literature that included questions about housing being asked of children or young people aged 0-18 years and their families accessing any healthcare or social service. We extracted data on the housing questions asked, source of housing questions, validity and descriptions of actions to address housing issues. RESULTS: Forty-nine peer-reviewed papers met the inclusion criteria. The housing questions in social screening tools vary widely. There are no standard housing-related questions that clinical and social service providers ask families. Fourteen screening tools were validated. An action was embedded as part of social screening activities in 27 of 42 studies. Actions for identified housing problems included provision of a community-based or clinic-based resource guide, and social prescribing included referral to a social worker, care coordinator or care navigation service, community health worker, social service agency, referral to a housing and child welfare demonstration project or provided intensive case management and wraparound services. CONCLUSION: This review provides a catalogue of housing questions that can be asked of families in the clinical and/or social service setting, and potential subsequent actions.

Experiences of healthcare providers of older adults with cancer during the COVID-19 pandemic.

OBJECTIVES: Care for older adults with cancer became more challenging during the COVID-19 pandemic. We sought to examine healthcare providers' clinical barriers, patient questions, and overall experiences related to care delivery for these patients during the pandemic. MATERIALS AND METHODS: Members of the Advocacy Committee of the Cancer and Aging Research Group along with the Association of Community Cancer Centers developed a 20-question survey for healthcare providers of older adults with cancer. Eligible participants were recruited by email sent through professional organizations' listservs, email blasts, and social media. This manuscript reports the qualitative data from the survey's three open-ended questions. Free text, open-ended survey items were analyzed by two independent coders for identification of common themes using NVivo software. Theme agreement was reached through consensus and count comparisons of participant responses were made. RESULTS: Healthcare system organizational challenges and meeting basic needs and support were commonly reported themes among respondents (n = 274). Barriers to care delivery included organizational challenges, patients' access to resources and support, concerns for patients' mental and physical health, and telehealth challenges. Respondents reported older adults were asking about their health and cancer care as well as access to basic needs and supports. Providers described worrying about patients' mental health, fear of personal safety, frustration in multi-level institutions, as well as experiencing positive leadership and communication. CONCLUSION: Providers are faced with balancing their concerns for personal and patient safety. These findings demand resources and support allocation for older adults with cancer and healthcare providers during the COVID-19 pandemic.

Survey of cancer care providers' attitude toward care for older adults with cancer during the COVID-19 pandemic.

OBJECTIVES: Care for older adults with cancer became more challenging during the COVID-19 pandemic. We sought to examine cancer care providers' attitudes toward the barriers and facilitators related to the care for these patients during the pandemic. MATERIALS AND METHODS: Members of the Advocacy Committee of the Cancer and Aging Research Group, along with the Association of Community Cancer Centers, developed the survey distributed to multidisciplinary healthcare providers responsible for the direct care of patients with cancer. Participants were recruited by email sent through four professional organizations' listservs, email blasts, and messages through social media. RESULTS: Complete data was available from 274 respondents. Only 15.4% had access to written guidelines that specifically address the management of older adults with cancer during the COVID-19 pandemic. Age was ranked fifth as the reason for postponing treatment following comorbid conditions, cancer stage, frailty, and performance status. Barriers to the transition to telehealth were found at the patient-, healthcare worker-, and institutional-levels. Providers reported increased barriers in accessing basic needs among older adults with cancer. Most respondents agreed (86.3%) that decision making about Do Not Resuscitate orders should be the result of discussion with the patient and the healthcare proxy in all situations. The top five concerns reported were related to patient safety, treatment delays, healthcare worker mental health and burnout, and personal safety for family and self. CONCLUSION: These findings demand resources and support allocation for older adults with cancer and healthcare providers during the COVID-19 pandemic.

How Is Geriatric Assessment Used in Clinical Practice for Older Adults With Cancer? A Survey of Cancer Providers by the American Society of Clinical Oncology.

PURPOSE: For patients with cancer who are older than 65 years, the 2018 ASCO Guideline recommends geriatric assessment (GA) be performed. However, there are limited data on providers' practices using GA. Therefore, ASCO's Geriatric Oncology Task Force conducted a survey of providers to assess practice patterns and barriers to GA. METHODS: Cancer providers treating adult patients including those ≥ 65 years completed an online survey. Questions included those asking about awareness of ASCO's Geriatric Oncology Guideline (2018), use of validated GA tools, and perceived barriers to using GA. Descriptive statistics and statistical comparisons between those aware of the Guideline and those who were not were conducted. Statistical significance was set at P < .05. RESULTS: Participants (N = 1,277) responded between April 5 and June 5, 2019. Approximately half (53%) reported awareness of the Guideline. The most frequently used GA tools, among those aware of the Guideline and those who were not, assessed functional status (69% v 50%; P < .001) and falls (62% v 45%; P < .001). Remaining tools were used < 50% of the time, including tools assessing weight loss, comorbidities, cognition, life expectancy, chemotherapy toxicity, mood, and noncancer mortality risk. GA use was two to four times higher among those who are aware of the Guideline. The most frequent barriers for those who reported being Guideline aware were lack of resources, specifically time (81.7%) and staff (77.0%). In comparison, those who were unaware of the Guideline most often reported the following barriers: lack of knowledge or training (78.4%), lack of awareness about tools (75.2%), and uncertainty about use of tools (75.0%). CONCLUSION: Among providers caring for older adults, 52% were aware of the ASCO Guideline. Some domains were assessed frequently (eg, function, falls), whereas other domains were assessed rarely (eg, mood, cognition). Guideline awareness was associated with two to four times increased use of GA and differing perceived barriers. Interventions facilitating Guideline-consistent implementation will require various strategies to change behavior.

Bringing Life to Death: The Need for Honest, Compassionate, and Effective End-of-Life Conversations.

Conversations about death and dying are a crucial part of all medical care and are particularly relevant in the field of oncology. Patients express a desire to have discussions about goals of care, and many patients have thought about their end-of-life (EOL) wishes but have not had an opportunity to openly talk with care providers about this. Deficiencies in medical training, lack of confidence, limited time, and cultural barriers all contribute to the paucity of these important discussions. Although physicians are often expected to lead these conversations, nurses and nurse practitioners also play a vital role in the identification of opportunities to address EOL goals and should be a resource for the care team in facilitating EOL conversations at all points on the care continuum. Public engagement is paramount in normalizing conversations about death and dying, and the health care system needs to partner with public health agencies and private groups to open dialogues about EOL. Providers at all levels need improved education in having these difficult but essential conversations.

Claymation art therapy in early phase psychosis: A qualitative study to explore participants' experiences with the program and identify outcome effects.

AIM: Art therapy is a complex intervention that has mixed evidence for people with schizophrenia and scant research in early phase psychosis. Benefits appear to depend on level of engagement and more qualitative studies are needed to elucidate how it works and what outcomes to measure. The purpose of this study was to determine the feasibility of a 13-week Claymation art therapy group intervention for young adults with early phase psychosis, and to explore participants' experiences with the program and to identify outcome effects. METHODS: Thirteen participants completed the intervention in two cohorts. The participants' experiences were explored through qualitative thematic analysis of individual interviews postintervention and at 3-month follow-up. RESULTS: The program had a 62% retention rate and an 80% attendance rate. Qualitative analysis of postintervention and 3-month follow-up interviews identified six themes that described program elements: (a) Claymation valued; (b) film screening fostered support; (c) getting to know each other through art; (d) connecting with others with lived experience; (e) opportunity to build skills; and (f) supportive facilitators. Five themes were identified as outcome effects from both time points: (a) stress relief; (b) self-discovery; (c) pride in art; (d) confidence and hope; and (e) engagement in meaningful activity postintervention. Two themes were unique to the 3-month follow-up interviews: (a) Claymation was enabling and (b) showing my film. CONCLUSIONS: This group Claymation art therapy intervention effectively engaged people with early phase psychosis and the qualitative analysis identified program elements and outcome effects that can be evaluated in future studies.

The underreporting of phase III chemo-therapeutic clinical trial data of older patients with cancer: A systematic review.

PURPOSE: Inspired by the American Society of Clinical Oncology's recommendations to strengthen the evidence base for older adults with cancer, the purpose of this systematic review is to identify the reporting of treatment efficacy and adverse events specific to older adults with cancer in Phase III chemo-therapeutic clinical trials. This review also investigates the frequency with which these data points were reported in the literature to identify gaps in reporting and opportunities to expand the knowledge base on clinical outcomes for older adults with cancer. METHODS: Chemo-therapeutic clinical trial data published from July 1, 2016 to June 30, 2017 was reviewed. Manuscripts (n = 929) were identified based on keyword searches of EMBASE and PubMed. After removal of duplicates (n = 116) and articles that did not meet this study's inclusion criteria (n = 654), 159 articles were identified for review. RESULTS: Reviewed papers were published in 36 different scientific journals and included twenty-five different cancer types. Of the 159 articles, 117 (73.6%) reported age-specific medians and 75 (47.2%) included stratifications of data by age. Treatment efficacy was reported in 96.2% of the articles with 39.9% reporting effectiveness of treatment by age. Reporting of adverse events was included in 84.9% of the articles with only 8.9% reporting these events stratified by age. CONCLUSION: Results suggest inadequate reporting of treatment efficacy and adverse events as well as basic descriptive statistics about the age distribution of study subjects. Conscious efforts are needed to address these deficiencies at every level of planning and conducting clinical trials as wells as reporting outcomes stratified by age. Ultimately, standardized reporting could lead to improved treatment decisions and outcomes for older adults with cancer.

Controversies in communication of genetic risk for hereditary breast cancer.

Increased availability and heightened consumer awareness of "cancer genes" has increased consumer interest in, and demand for breast cancer risk assessment, and thus a pressing need for providers to identify effective, efficient methods of communicating complicated genetic information to consumers and their potentially at-risk relatives. With increasing direct-to-consumer and -physician marketing of predictive genetic tests, there has been considerable growth in web- and telephone-based genetic services. There is urgent need to further evaluate the psychosocial and behavioral outcomes (i.e., risks and benefits) of telephone and web-based methods of delivery before they become fully incorporated into clinical care models. Given the implications of genetic test results for family members, and the inherent conflicts in health care providers' dual responsibilities to protect patient privacy and to "warn" those at-risk, new models for communicating risk to at-risk relatives are emerging. Additional controversies arise when the at-risk relative is a minor. Research evaluating the impact of communicating genetic risk to offspring is necessary to inform optimal communication of genetic risk for breast cancer across the lifespan. Better understanding the risks and benefits associated with each of these controversial areas in cancer risk communication are crucial to optimizing adherence to recommended breast cancer risk management strategies and ensuring psycho-social well-being in the clinical delivery of genetic services for breast cancer susceptibility.
