Development and validation of a patient reported experience measure for experimental cancer medicines (PREM-ECM) and their carers (PREM-ECM-Carer).

BACKGROUND: Our aim was to develop a validated Patient Reported Experience Measure (PREM) to capture patient and carer experience during participation in experimental cancer medicine trials (ECM): called PREM-ECM. METHODS: Mixed method design, consisting of four stages. Questionnaire items were produced for both patients and carers using interviews, focus groups, and cognitive interviews with patients and carers separately. For both patient and carer PREMs, a cross-sectional questionnaire study was conducted to identify final items for inclusion using hierarchical item reduction and Rasch analysis. Questionnaire validity and reliability were assessed, including administration feasibility. RESULTS: Initial interview participants suggested the need for three PREMs, two specific to patients: (i) a 'prior' questionnaire that captured experiences of trial introduction, screening, consenting, and early trial experience (< 6 weeks post consent); and (ii) 'on-trial' that captured experiences of ongoing consent and trial participation; and (iii) a PREM specific for carers. The draft 25-item 'prior' questionnaire was completed by 162 patients and 162 patients completed the draft 35-item 'on-trial' questionnaire. Hierarchical and Rasch analysis produced a 14-item 'prior' list and a 15-item list for 'on-trial'. Both patient PREM's demonstrated a good fit to the Rasch model following Bonferroni correction (X2p = 0.008). The carer 34-draft item questionnaire was completed by 102 participants. Hierarchical and Rasch analysis produced a 13-item list for PREM-ECM-Carer, with good fit to the Rasch model ( X2p = 0.62). The pilot testing demonstrated the feasibility of all the PREMs in capturing patient and caregiver experiences in routine clinical settings. CONCLUSIONS: The three PREM-ECM questionnaires will be the first validated experience measures for ECM trial patients and their carers. These questionnaires may be used to assess patients' and their carers' experiences of ECM and enable robust comparisons across cancer trial units highlighting areas for service improvement.

A pragmatic qualitative study to explore women's and clinicians' experience of access to systemic anti-cancer therapies for the treatment of secondary breast cancer.

PURPOSE: An estimated 57,000 women are currently living with secondary (metastatic) breast cancer across the UK. Equitable access to treatment has been associated with improved clinical outcomes, however geographical disparities have been reported which remain poorly understood. The purpose of our study was to explore women and clinicians' experience of geographic access to systemic anti-cancer therapies for the treatment of secondary breast cancer. METHOD: The study setting was the integrated cancer system across the northwest region of Greater Manchester UK. A pragmatic qualitative study design was used. Women aged >18 years with a confirmed SBC diagnosis and clinicians responsible for the care and treatment of women with a secondary breast cancer diagnosis were interviewed using semi structured interviews to elicit their experience and perspectives on geographic access to treatment. Data were analysed using thematic analysis to identify emergent themes. RESULTS: Eighteen interviews with women and 12 interviews with clinicians were completed. Four meta-themes were identified for geographic access, the influence of the health care system, person centred factors and the impact of Covid-19 on treatment access and receipt. CONCLUSION: Our study was the first of its kind to explore women and clinicians experience of geographic access to systemic anti-cancer therapies for the treatment of secondary breast cancer. Findings provided a greater understanding of distance decay and the influence of the health care system on treatment access. This included the importance and availability of clinical trials as a potential treatment option. This provided important insights and contributed to ongoing debate.

A novel insecticide, isocycloseram, shows promise as an alternative to chlorpyrifos against a direct pest of peanut, Diabrotica undecimpunctata howardi (Coleoptera: Chrysomelidae).

Larvae of the southern corn rootworm (SCR) Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae) are primary pests of peanut in the Virginia-Carolina region of the United States, and are relatively sporadic pests in southern states such as Georgia, Alabama, and Florida. Peanuts have strict quality standards which, when they are not met, can diminish crop value by more than 65%. Management of direct pests like SCR is therefore crucial to maintaining the economic viability of the crop. The soil-dwelling nature of SCR larvae complicates management due to difficulties associated with monitoring and predicting infestations. Nonchemical management options are limited in this system; preventative insecticide applications are the most reliable management strategy for at-risk fields. Chlorpyrifos was the standard product for larval SCR management in peanut until its registration was revoked in 2022, leaving no effective chemical management option for larvae. We tested a novel insecticide, isocycloseram, for its ability to reduce pod scarring, pod penetration, and non-SCR pod damage in field studies conducted in Suffolk, Virginia in 2020-2022. Overall injury was low in 2020 and 2022, and in 2022 there was not a significant effect of treatment. In 2021, 2 simulated chemigation applications of isocycloseram in July significantly reduced pod scarring and overall pod injury relative to chlorpyrifos and the untreated control. Our results suggest that isocycloseram may become an effective option for managing SCR in peanut, although more work is needed to understand the mechanisms by which it is effective as a soil-applied insecticide.

Geographic and sociodemographic access to systemic anticancer therapies for secondary breast cancer: a systematic review.

BACKGROUND: The review aimed to investigate geographic and sociodemographic factors associated with receipt of systemic anticancer therapies (SACT) for women with secondary (metastatic) breast cancer (SBC). METHODS: Included studies reported geographic and sociodemographic factors associated with receipt of treatment with SACT for women > 18 years with an SBC diagnosis. Information sources searched were Ovid CINAHL, Ovid MEDLINE, Ovid Embase and Ovid PsychINFO. Assessment of methodological quality was undertaken using the Joanna Briggs Institute method. Findings were synthesised using a narrative synthesis approach. RESULTS: Nineteen studies published between 2009 and 2023 were included in the review. Overall methodological quality was assessed as low to moderate. Outcomes were reported for treatment receipt and time to treatment. Overall treatment receipt ranged from 4% for immunotherapy treatment in one study to 83% for systemic anticancer therapies (unspecified). Time to treatment ranged from median 54 days to 95 days with 81% of patients who received treatment < 60 days. Younger women, women of White origin, and those women with a higher socioeconomic status had an increased likelihood of timely treatment receipt. Treatment receipt varied by geographical region, and place of care was associated with variation in timely receipt of treatment with women treated at teaching, research and private institutions being more likely to receive treatment in a timely manner. CONCLUSIONS: Treatment receipt varied depending upon type of SACT. A number of factors were associated with treatment receipt. Barriers included older age, non-White race, lower socioeconomic status, significant comorbidities, hospital setting and geographical location. Findings should however be interpreted with caution given the limitations in overall methodological quality of included studies and significant heterogeneity in measures of exposure and outcome. Generalisability was limited due to included study populations. Findings have practical implications for the development and piloting of targeted interventions to address specific barriers in a socioculturally sensitive manner. Addressing geographical variation and place of care may require intervention at a commissioning policy level. Further qualitative research is required to understand the experience and of women and clinicians. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020196490.

Enhanced supportive care: prospective cohort study of oncology patients and caregivers.

OBJECTIVES: A prospective cohort study to evaluate clinical effectiveness of the enhanced supportive care (ESC) service at a comprehensive cancer centre and to explore the impact of the service on patient and caregiver outcomes and experience. METHODS: Patients who received care under the ESC service and their caregivers were eligible. Consented patients (n=184) and caregivers (n=67) completed questionnaires at baseline, 4 weeks and 8 weeks post-ESC. Patient questionnaires assessed quality of life (QOL), symptoms, experience of ESC and health service use. Caregiver questionnaires included QOL and needs assessment. Selected patients (n=13) participated in qualitative interviews. Quantitative analysis explored differences in questionnaire responses over time (p<0.05). Qualitative data were analysed thematically. RESULTS: Patient quantitative data showed improvements in QOL (p=0.004 for European Quality of Life Questionnaire 5 dimensions (EQ5D) health index scores) and anxiety (p=0.006) at 4 weeks, reduction in some symptoms (pain p=0.02 at 4 weeks), improvement in self-efficacy, an increase in problems being addressed and a decrease in health service use (reduction in outpatient appointments). Qualitative findings suggested patients were generally satisfied with the ESC service but identified areas for improvement such as increased awareness of ESC and earlier referral. Fewer improvements were noted for caregivers; however, they did report a decrease in unmet needs. CONCLUSION: The ESC service had a positive impact on various patient-reported and caregiver-reported outcomes. There were also positive impacts on health service use. Increasing awareness of ESC and engaging patients at an earlier stage in the disease trajectory may further improve patient satisfaction and outcomes.

Patient-reported outcome (PRO) instruments used in patients undergoing adoptive cell therapy (ACT) for the treatment of cancer: a systematic review.

INTRODUCTION: Adoptive cell therapy (ACT) is a rapidly evolving field. Patient-reported outcomes (PROs) allow patients to report the impact of treatment on their quality of life during and after treatment. The systematic review aims to characterise the breadth of PROs utilised in ACT cancer care and provide guidance for the use of PROs in this patient population in the future. METHODS: A systematic search was conducted (MEDLINE, PsycINFO, Embase and CINAHL) in August 2021 by two reviewers. Search terms covered the following: "adoptive cell therapy", "patient-reported outcomes" and "cancer". Studies were included if they used a PRO measure to report the impact of ACT. The methodological quality of PROs was assessed. Forward and backward reference searching was conducted of any relevant papers. A quality grading scale was applied based on Cochrane and Revenson criteria for classification of high-quality studies. Key data from the studies and the included PROs was extracted by two researchers and tabulated. RESULTS: One-hundred nine papers were identified; 11 papers were included. The majority of studies were single-arm trials or observational studies. Twenty-two different PROs were identified; none was ACT specific. The PROMIS-29 and EQ-5D were most commonly used. Few studies collected PRO data in the first 1-2 weeks. Four studies followed patients up for over a year, and a further four studies followed patients for approximately 3 months. DISCUSSION: None of the PROs identified have been designed specifically for ACT. Appropriateness of existing instruments should be considered. It should be considered whether it is appropriate to collect data more frequently in the acute stage and then less frequently during follow-up. It should be considered if one tool is suitable at all time points or if the tool should be adapted depending on time since treatment. More research is needed to identify the exact timings of PRO assessments, and qualitative work with patients is needed to determine the most important issues for them throughout the treatment and follow-up.

Therapists' Perception on Quality of Provider Communication While Wearing a Mask: Impact of a Pandemic.

During the COVID-19 pandemic, the Centers for Disease Control and Prevention established infection prevention recommendations, resulting in hospital systems adopting universal mask-wearing. Mask-wearing and its impact on patient-provider communication have been highlighted, yet have not been systematically studied to date. The purpose of this study was to assess the impact of mask-wearing on provider communication during wheelchair education. Allied health professionals (65 physical and occupational therapists and 1 other) completed a 24-item, online self-report survey on the impact of provider mask-wearing on communication with patients and/or their caregivers during wheelchair education. This survey contained questions, graded on 5-point Likert-like scales, regarding the perceived impact of mask-wearing on the quality of communication efficiency and effectiveness, the types and frequency of communication strategies used to enhance communication during breakdowns, knowledge/confidence in implementing communication strategies, and preferences for additional training. Results indicated that mask-wearing impacted communication, yet clinicians made adaptations of various verbal and nonverbal communication strategies to avoid disruptions in providing education. Clinicians identified training preferences for additional support with provider communication. As the pandemic continues, patient-provider communication can be supported through targeted training in communication strategies.

Extended Sentinel Monitoring of Helicoverpa zea Resistance to Cry and Vip3Aa Toxins in Bt Sweet Corn: Assessing Changes in Phenotypic and Allele Frequencies of Resistance.

Transgenic corn and cotton that produce Cry and Vip3Aa toxins derived from Bacillus thuringiensis (Bt) are widely planted in the United States to control lepidopteran pests. The sustainability of these Bt crops is threatened because the corn earworm/bollworm, Helicoverpa zea (Boddie), is evolving a resistance to these toxins. Using Bt sweet corn as a sentinel plant to monitor the evolution of resistance, collaborators established 146 trials in twenty-five states and five Canadian provinces during 2020-2022. The study evaluated overall changes in the phenotypic frequency of resistance (the ratio of larval densities in Bt ears relative to densities in non-Bt ears) in H. zea populations and the range of resistance allele frequencies for Cry1Ab and Vip3Aa. The results revealed a widespread resistance to Cry1Ab, Cry2Ab2, and Cry1A.105 Cry toxins, with higher numbers of larvae surviving in Bt ears than in non-Bt ears at many trial locations. Depending on assumptions about the inheritance of resistance, allele frequencies for Cry1Ab ranged from 0.465 (dominant resistance) to 0.995 (recessive resistance). Although Vip3Aa provided high control efficacy against H. zea, the results show a notable increase in ear damage and a number of surviving older larvae, particularly at southern locations. Assuming recessive resistance, the estimated resistance allele frequencies for Vip3Aa ranged from 0.115 in the Gulf states to 0.032 at more northern locations. These findings indicate that better resistance management practices are urgently needed to sustain efficacy the of corn and cotton that produce Vip3Aa.

The Spatiotemporal Distribution, Abundance, and Seasonal Dynamics of Cotton-Infesting Aphids in the Southern U.S.

Cotton leafroll dwarf virus (CLRDV) is an emerging aphid-borne pathogen infecting cotton, Gossypium hirsutum L., in the southern United States (U.S.). The cotton aphid, Aphis gossypii Glover, infests cotton annually and is the only known vector to transmit CLRDV to cotton. Seven other species have been reported to feed on, but not often infest, cotton: Protaphis middletonii Thomas, Aphis craccivora Koch, Aphis fabae Scopoli, Macrosiphum euphorbiae Thomas, Myzus persicae Sulzer, Rhopalosiphum rufiabdominale Sasaki, and Smynthurodes betae Westwood. These seven have not been studied in cotton, but due to their potential epidemiological importance, an understanding of the intra- and inter-annual variations of these species is needed. In 2020 and 2021, aphids were monitored from North Carolina to Texas using pan traps around cotton fields. All of the species known to infest cotton, excluding A. fabae, were detected in this study. Protaphis middletonii and A. gossypii were the most abundant species identified. The five other species of aphids captured were consistently low throughout the study and, with the exception of R. rufiabdominale, were not detected at all locations. The abundance, distribution, and seasonal dynamics of cotton-infesting aphids across the southern U.S. are discussed.

Understanding the impact of radiotherapy related insufficiency fractures and exploring satisfaction with two existing patient reported outcome measures: A qualitative interview study.

Introduction: Radiotherapy related insufficiency fractures (RRIFs) occur in approximately 10-15% of cancer survivors who underwent pelvic radiotherapy. Little research has been conducted to explore the impact of RRIFs on quality of life (QOL). Patient reported outcome measures (PROMs) are often used in oncology to measure side effects and QOL. The study aims to understand the influence of RRIF on QOL and to discover whether available PROMs address their needs. Materials and methods: Twenty-five patients randomly selected from a Tertiary Oncology Centre bone health clinic database of patients referred with RRIFs were approached. Interested patients were sent two existing PROMs and a patient information sheet. Eleven patients agreed to take part in a semi-structured interview to explore their experiences and their opinion on the existing PROMs. Telephone interviews were conducted. Interviews were audio recorded, transcribed, and analysed using thematic analysis. Results: Four themes were identified: 1) Route to diagnosis, 2) management of RRIFs and 3) resilience all had an impact on 4) QOL. Additionally, participants discussed PROMs and how they might be integrated into clinical practice. The data highlights the wide ranging QOL impacts experienced and highlights potential areas for improvement in terms of diagnosis and management pathways. Discussion: The impact of RRIFs on QOL is considerable. Participants highlighted key areas for improvement including the provision of more information, more access to support and improved management pathways. Participants also highlighted the potential benefits of PROMs but suggested existing measures could be improved.

Ground beetles suppress slugs in corn and soybean under conservation agriculture.

Conservation agriculture practices such as eliminating tillage and planting high residue cover crops are becoming increasingly important in field crop systems in the US Mid-Atlantic. However, these practices have sometimes been associated with an increase in moderate to severe damage to field crops by slugs. Conserving natural enemy populations is a desirable way to manage slug infestations because remedial control measures are limited. Here, we tested the effects of conservation practices, weather, and natural enemies on slug activity-density measured by tile traps placed among 41 corn and soybean fields during the spring of 2018 and 2019 in the Northern Shenandoah Valley, Virginia, USA. We found that a positive effect of cover crops on slug activity-density was reduced by tillage and that slug activity-density declined with increasing ground beetle activity-density. Slug activity-density also declined with decreasing rainfall and increasing average temperature. Weather was the only significant predictor of ground beetle activity-density, which was reduced in sites and weeks that were relatively hot and dry or that were cool and wet. However, we also found a marginally significant negative effect of pre-plant insecticides on ground beetles. We suggest that the observed interacting effects of cover crops and tillage reflect favorable conditions for slugs provided by increased small grain crop residue that can be mitigated to some extent by even low levels of tillage. More broadly, our study suggests that implementation of practices known to promote recruitment of ground beetles in crop fields can improve natural suppression of slugs in corn and soybean that are being increasingly cultivated according to conservation agriculture practices.

Removing neonicotinoid seed treatments has negligible effects on refuge function and crop protection in transgenic maize targeting western corn rootworm (Coleoptera: Chrysomelidae).

Nearly all maize seed sold in the United States includes a neonicotinoid seed treatment (NST), meant to protect seedlings against early-season insect pests. For key pests, including western corn rootworm (Diabrotica virgifera virgifera LeConte) (D.v.v), insecticidal proteins derived from Bacillus thuringiensis (Bt) are expressed in plant tissues as alternatives to soil-applied insecticides. Insect resistance management (IRM) plans use non-Bt "refuges" to encourage survival of Bt-susceptible D.v.v., which maintains susceptible alleles in the population. In non-cotton producing regions, IRM guidelines require a minimum 5% blended refuge for maize expressing more than 1 trait targeting D.v.v. Prior work has shown that 5% blends yield insufficient proportions of refuge beetles to contribute reliably to IRM. Whether NSTs interfere with survivorship of refuge beetles is unknown. Our objective was to determine whether NSTs affect proportions of refuge beetles, and secondarily, to determine whether NSTs provide agronomic advantages over Bt seed alone. To reveal host plant type (i.e., Bt or refuge), we used a stable isotope (15N) to mark refuge plants in plots with 5% seed blends. To assess refuge performance between treatments, we compared proportions of beetles from respective natal hosts. In all site-years, NSTs showed inconsistent effects on proportions of refuge beetles. Treatment comparisons showed inconsistent agronomic benefits of NSTs when combined with Bt traits. Our results demonstrate that NSTs have a negligible impact on refuge performance and reinforces the assertion that 5% blends are serving little benefit for IRM. Plant stand and yield were not improved by NSTs.

The experience of patients with lung cancer during the COVID-19 pandemic and its importance for post-pandemic outpatient cancer care planning: A cross sectional study exploring the roles of age and frailty.

INTRODUCTION: The COVID-19 pandemic impacted the care and experiences of people with cancer, but it presented an opportunity to improve the delivery of outpatient care post-pandemic. MATERIALS AND METHODS: We performed an observational cross-sectional study with people with lung cancer throughout the COVID-19 pandemic. A survey investigated patients' experiences and preferences regarding the delivery of cancer care to plan for post-pandemic care, as well as the pandemic's impact on their functional status (physical and psycho-social), exploring the role of age and frailty. RESULTS: Amongst 282 eligible participants, 88%, 86%, and 59% of patients reported feeling appropriately supported during the pandemic by their cancer centre, friends/family, and primary care services, respectively. Remote oncology consultations were delivered to 90% of patients during the pandemic, of which 3% did not meet patients' expectations. Regarding post-pandemic outpatient care preferences, face-to-face appointments were preferred by 93% for the first appointment, by 64% when discussing imaging results, and by 60% for reviews during anti-cancer treatments. Older patients aged 70 years and above were more likely to favour face-to-face appointments (p = 0.007), regardless of their frailty status. Patient preferences changed over time, with the more recent participants preferring remote appointments during anti-cancer treatments (p = 0.0278). Regarding the pandemic's impact, abnormal levels of anxiety and depression were found in 16% and 17% of patients, respectively. Younger patients experienced higher abnormal levels of anxiety and depression (p = 0.036, p = 0.021). Amongst the older sub-group, those with frailty had higher levels of anxiety and depression (p < 0.001). Amongst all participants, 54% reported a considerable negative impact from the pandemic on different aspects of their daily life, particularly emotional and psychological health and sleep patterns, which were more marked in younger patients and the older sub-group with frailty. Older patients without frailty reported the least impact on their functional status. DISCUSSION: There is a need for more personalised outpatient consultation options during cancer care. Whilst there is a preference for face-to-face consultations for older patients, following the pandemic there is a growing acceptance of remote consultations particularly during anti-cancer treatment. Older patients with lung cancer without frailty were less affected by the pandemic than those with frailty and younger patients, requiring less support from healthcare services.

Magnitude and Extent of Helicoverpa zea Resistance Levels to Cry1Ac and Cry2Ab2 across the Southeastern USA.

After resistance is first detected, continued resistance monitoring can inform decisions on how to effectively manage resistant populations. We monitored for resistance to Cry1Ac (2018 and 2019) and Cry2Ab2 (2019) from southeastern USA populations of Helicoverpa zea. We collected larvae from various plant hosts, sib-mated the adults, and tested neonates using diet-overlay bioassays and compared them to susceptible populations for resistance estimates. We also compared LC50 values with larval survival, weight and larval inhibition at the highest dose tested using regression, and found that LC50 values were negatively correlated with survival for both proteins. Finally, we compared resistance rations between Cry1Ac and Cry2Ab2 during 2019. Some populations were resistant to Cry1Ac, and most were resistant to CryAb2; Cry1Ac resistance ratios were lower than Cry2Ab2 during 2019. Survival was positively correlated with larval weight inhibition for Cry2Ab. This contrasts with other studies in both the mid-southern and southeastern USA, where resistance to Cry1Ac, Cry1A.105, and Cry2Ab2 increased over time and was found in a majority of populations. This indicates that cotton expressing Cry proteins in the southeastern USA was at variable risk for damage in this region.

Assessing the Acceptability of Home Blood Monitoring for Patients With Cancer Who Are Receiving Systemic Anticancer Therapy From a Patient, Caregiver, and Clinician Perspective: Focus Group and Interview Study.

BACKGROUND: Regular blood testing is an integral part of systemic anticancer therapy delivery. Blood tests are required before every administration of treatment to ensure that a patient is sufficiently well to receive it. Blood testing is burdensome for patients as they require either an extra visit within 48 hours of planned administration of treatment or a significantly long visit if performed on the day of treatment. The additional time for appointments can have a significant impact on the quality of life of someone who is living with cancer. In the United Kingdom, the COVID-19 pandemic created unprecedented disruption to the delivery of cancer care. Face-to-face hospital visits were reduced, resulting in the need to develop more innovative ways of working to minimize treatment interruptions. This led to significant uptake of digital technologies, with new models of care rapidly deployed across the UK health service to meet these challenges. OBJECTIVE: This study aimed to explore the acceptability of a point-of-care home blood monitoring device for people with cancer who are receiving systemic anticancer therapy, which is being developed in response to the increased need for remote care for patients with cancer. METHODS: Qualitative focus groups and semistructured interviews were conducted with patients (23/47, 49%), caregivers (6/47, 13%), and health care professionals (18/47, 38%) over a 19-month time frame from May 2019 to December 2020. Data were analyzed using framework analysis guided by the Unified Theory of Acceptance and Use of Technology model. RESULTS: Analysis identified 4 overarching themes: performance expectancy, effort expectancy, social influence, and facilitating conditions. CONCLUSIONS: This study found that patients with cancer, their caregivers, and health care professionals had positive perceptions about home blood monitoring. Although they are often considered synonymously, self-testing and self-management are not mutually exclusive, and this study illustrated some disparity in opinions regarding patient self-management. Home blood monitoring has the potential to provide patients with cancer with a convenient option for blood monitoring. It would minimize hospital attendances, decrease late treatment deferrals, and provide prompt recognition of cancer treatment toxicities, thus enhancing the existing nurse-led protocols and clinical pathways. Home blood monitoring would create a long-term sustainable transformation for the delivery of cancer care, using digital health to act as a facilitator to address a pertinent issue regarding improving the efficiency of hospital resources and increasing the delivery of personalized patient care. Further studies are needed to determine how and where home blood monitoring would fit within clinical pathways, in a way that is robust and equitable.

Understanding the experiences of lung cancer patients during the COVID-19 pandemic: a qualitative interview study.

PURPOSE: The study explores experiences of lung cancer patients during COVID-19 and considers how changes to care delivery and personal lives affected patient needs. METHODS: Semi-structured telephone interviews were conducted to explore experiences of lung cancer patients during COVID-19. Interviews were audio-recorded, transcribed verbatim and analysed thematically. Interview participants were purposively selected based on age, gender, treatment status, timing of diagnosis (pre/post first COVID-19 lockdown) from a sample of lung cancer patients (any histological subtype/any cancer stage/any point in treatment) who had completed a questionnaire exploring how participants' lives were impacted by the pandemic and their thoughts on clinical care and remote communication. RESULTS: Thirty lung cancer patients who participated in the questionnaire study were approached and participated in an interview. Three themes were identified: (1) Adapting to new modes of communication (focusing on experiences of remote communication); (2) Experience of care delivery during the pandemic (describing how all aspects of care delivery had been affected); (3) Impact of the COVID-19 pandemic on quality of life (QOL) (focus on the psychological impact and feeling of reduced support). Themes 1 and 2 are heavily interlinked and both had bearing on patients' QOL experience. CONCLUSION: Lung cancer patients were impacted psychologically by changes to care delivery and changes in their personal life. The findings highlight some benefits to remote consultations but the stage of the treatment pathway and illness trajectory should be considered when determining if this is appropriate. Participants felt support from peers, family and friends was limited during the pandemic.

Inpatient rehabilitation wheelchair management quality improvement project: Implications for patients with spinal cord injury.

Context/Objective: Evaluate hospital fleet wheelchair (WC) requests submitted by physical therapists (PT) for patients with spinal cord injury (SCI) to trial and use during inpatient rehabilitation.Design: Quality improvement project secondary analysis of delivery process and WC trials.Setting: Urban inpatient rehabilitation hospital.Participants: Internal review of 4,371 WC requests narrowed to 750 patients with SCI.Interventions: PTs submitted WC requests between March 25, 2017, and September 30, 2019.Outcome Measures: WC delivery timeframe, level of SCI, type of WC.Results: PTs requested power (28%), and manual WC bases: standard (19.1%), tilt (18.9%), ultralight rigid (18.9%), ultralight folding (13.5%), and recliner (1.6%) respectively. Patients received fleet WCs 49.9% of the time within specified urgency timeframes. A Chi-Square test showed a significant association between WC request urgency and fulfillment within established timeframes (χ2 = 19.68, P < 0.001, n = 750). Broken down by urgency level: 60.0% low (n = 12), 56.2% medium (n = 244), and 39.9% high (n = 118) received their WC within established timeframes. Patients with cervical level SCI (n = 162) had the highest mean wait time of 8.28 days for power WCs. The second highest wait time was 6.29 days (SD 6.6) for manual ultralight rigid WCs (n = 34).Conclusion: Inpatient fleet WC delivery is critical to patients with SCI. Variation occurs by WC type requested and by the level of injury. Gaps exist in providing appropriate WCs in facility timeframe guidelines by the level of urgency that is within 24 h for high, 3-5 days for medium, and 5-7 days for low.

Pest population dynamics are related to a continental overwintering gradient.

Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects that are partitioned into three geographic zones. Seasonal populations were initially detected in the southern range, where they experienced multiple large population peaks. All three zones experienced a final peak between late July (southern range) and mid-August to mid-September (transitional zone and northern limits). The southern range expanded by 3% since 1981 and is projected to increase by twofold by 2099 but the areas of other zones are expected to decrease in the future. These changes suggest larger populations may persist at higher latitudes in the future due to reduced low-temperature lethal events during winter. Because H. zea is a highly migratory pest, predicting when populations accumulate in one region can inform synchronous or lagged population development in other regions. We show the value of combining long-term datasets, remotely sensed data, and laboratory findings to inform forecasting of insect pests.

Evaluating invasion risk and population dynamics of the brown marmorated stink bug across the contiguous United States.

BACKGROUND: Invasive species threaten the productivity and stability of natural and managed ecosystems. Predicting the spread of invaders, which can aid in early mitigation efforts, is a major challenge, especially in the face of climate change. While ecological niche models are effective tools to assess habitat suitability for invaders, such models have rarely been created for invasive pest species with rapidly expanding ranges. Here, we leveraged a national monitoring effort from 543 sites over 3 years to assess factors mediating the occurrence and abundance of brown marmorated stink bug (BMSB, Halyomorpha halys), an invasive insect pest that has readily established throughout much of the United States. RESULTS: We used maximum entropy models to estimate the suitable habitat of BMSB under several climate scenarios, and generalized boosted models to assess environmental factors that regulated BMSB abundance. Our models captured BMSB distribution and abundance with high accuracy, and predicted a 70% increase in suitable habitat under future climate scenarios. However, environmental factors that mediated the geographical distribution of BMSB were different from those driving abundance. While BMSB occurrence was most affected by winter precipitation and proximity to populated areas, BMSB abundance was influenced most strongly by evapotranspiration and solar photoperiod. CONCLUSION: Our results suggest that linking models of establishment (occurrence) and population dynamics (abundance) offers a more effective way to forecast the spread and impact of BMSB and other invasive species than simply occurrence-based models, allowing for targeted mitigation efforts. Implications of distribution shifts under climate change are discussed. © 2022 The Authors. Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.
