    Abstract From 2022, the European Union Waste Framework Directive (WFD) requires member states to report annual food waste from each food supply chain stage. Comprehensive food losses and waste (FLW) data can be challenging to obtain for the primary production stage, i.e., farming and fishing. However, this information is vital in developing FLW mitigation actions appropriate to each country. This study describes the nature and extent of FLW from primary production in Ireland, using methods approved for WFD reporting. Causes of FLW and FLW as a proportion of total production were determined through interviews with Irish primary production stakeholders and using national FLW data where available. The FLW was presented for each primary production sector - animal husbandry, horticulture, tillage, aquaculture, and fisheries. The total annual FLW from Irish primary production was 189,508 tonnes. The main FLW sources were vegetable production (122,398 tonnes), meat production (41,726 tonnes), and tillage (12,502 tonnes). The activities associated with high FLW did not reflect the quantity of food from those activities, e.g., dairy generated the greatest quantity of animal husbandry produce (89%) but only 7% of animal husbandry FLW. The main causes of FLW in Irish primary production were pests, disease, injuries, and production stress (37%), followed by un-harvestable or un-saleable produce, 24% and 21%, respectively. The majority of FLW described in this study (63%) is considered food loss, meaning mitigation efforts should focus on this rather than food waste. These results also clearly indicate priority areas for mitigation action, e.g., horticulture. This research suggests mitigation actions that improve long-term farm sustainability, e.g., improve soil health, reduce FLW and contribute to food production potential in fisheries and aquaculture.

    Abstract The largest portion of breast cancer patients diagnosed after 70 years of age present with hormone receptor-positive (HR+) breast cancer subtypes. Cyclin-dependent kinase (CDK) 4/6 inhibitor treatment, in conjunction with endocrine therapy, has become standard-of-care for metastatic HR+ breast cancer. In total, 320 patients with metastatic breast cancer receiving CDK4/6 inhibitor combined with fulvestrant or an aromatase inhibitor were enrolled in an ongoing observational study or were included in an IRB-approved retrospective study. All patients receiving CDK4/6 inhibitor-based therapy that were ≥70 years of age (n = 111) displayed prolonged progression-free survival (27.6 months) as compared to patients <70 years of age (n = 209, 21.1 months, HR = 1.38,

    Abstract Introduction: Encouraging safe work practices (SWPs) is challenging in agriculture. Group-based social learning has effectively promoted SWPs and health behaviors in other occupations, and could be applied in agriculture (e.g., through farmer discussion groups (DGs)). In Ireland, dairy DG members are more likely to adopt novel technologies and practices, a relationship that might extend to SWPs. The extent of SWP adoption among Irish dairy farmers is unknown. This paper evaluates a 2018 baseline study of SWP implementation, conducted as part of a dairy DG-based intervention study.
    Method: A paper-based survey of SWP implementation and safety self-perception was distributed to 1,220 farmers from 84 dairy DGs. For eight SWPs, associated with high-risk farm hazards (livestock, slurry, machinery, or tractors), farmers were asked how frequently they implemented these practices in the previous year, and how frequently they intended to do so next year (0: never, 1: rarely, 2: sometimes, 3: most of the time, 4: all of the time).
    Results: Surveys were completed by 460 farmers. For the previous year, three SWPs, related to slurry, machinery, and tractor hazards, scored a median frequency of four. Four SWPs, related to livestock, slurry, and machinery hazards, scored a median frequency of three. The lowest median score (two) was for tractor exit behavior. Median intention scores matched or exceeded past frequency for all SWPs, while 73% intended to increase implementation of at least one SWP. Most (96%) considered themselves a "safe farmer."
    Conclusions: Farmers generally perceived themselves to be safe at work, which is reflected in their SWP implementation. Most farmers intended to increase SWP implementation, suggesting awareness of safety shortcomings and a desire to farm more safely.
    Practical applications: This study can inform farm safety promotion initiatives. The disconnect between farmers' safety self-perception and SWP implementation merits further research.

    Abstract Despite widespread use and a known mechanism of action for CDK4/6 inhibitors in combination with endocrine therapy, features of disease evolution and determinants of therapeutic response in the real-world setting remain unclear. Here, a cohort of patients treated with standard-of-care combination regimens was utilized to explore features of disease and determinants of progression-free survival (PFS) and overall survival (OS). In this cohort of 280 patients, >90% of patients were treated with palbociclib in combination with either an aromatase inhibitor (AI) or fulvestrant (FUL). Most of these patients had modified Scarff-Bloom-Richardson (SBR) scores, and ER, HER2, and PR immunohistochemistry. Both the SBR score and lack of PR expression were associated with shorter PFS in patients treated with AI combinations and remained significant in multivariate analyses (HR = 3.86, p = 0.008). Gene expression analyses indicated substantial changes in cell cycle and estrogen receptor signaling during the course of treatment. Furthermore, gene expression-based subtyping indicated that predominant subtypes changed with treatment and progression. The luminal B, HER2, and basal subtypes exhibited shorter PFS in CDK4/6 inhibitor combinations when assessed in the pretreatment biopsies; however, they were not associated with OS. Using unbiased approaches, cell cycle-associated gene sets were strongly associated with shorter PFS in pretreatment biopsies irrespective of endocrine therapy. Estrogen receptor signaling gene sets were associated with longer PFS particularly in the AI-treated cohort. Together, these data suggest that there are distinct pathological and biological features of HR+/HER2- breast cancer associated with response to CDK4/6 inhibitors. Clinical trial registration number: NCT04526587.

    Abstract To systematically develop a farm safety intervention for farmer peer learning groups, to support safe working practice adoption. An iterative, multi-actor process was used, guided by the Intervention Mapping framework and the Socio-Ecological Model. The target peer learning groups were Irish dairy farmer discussion groups (DDGs). Literature review, semi-structured interviews, surveys, and participant observation informed an initial intervention design, which provided a starting point for collaborative intervention development. The final design comprised two intervention approaches, A and B, differing in frequency and discussion length. In a seven-month cluster-randomised, controlled pilot study, 76 DDGs implemented the design. The designs were standardised but adaptable to individual group interests and schedules. Pre-pilot feedback from farm advisors (intervention deliverers), and farmer and advisor recruitment, indicated good intervention acceptability initially. Challenges were experienced during implementation, but 52% of DDGs participating in the infrequent, long discussions approach (‘A’) and 72% of those in the frequent, short discussions approach (‘B’) completed at least some of the protocol. The multi-actor approach resulted in two flexible, acceptable designs, responsive to group culture and dynamics. Frequent, short discussions were acceptable to a greater number of groups than infrequent, long discussions. The Socio-Ecological Model, combined with multi-actor Intervention Mapping, provided a robust framework for the development of acceptable, practical, evidence-based farm safety and health promotion initiatives. The systematic public health research-driven approach evolved iteratively to a DDG practice-driven approach, through integration of Intervention Mapping with collaborative multi-actor design.

    Abstract Objectives: Occupational safety and health (OSH) interventions emphasizing regulation or education have had limited success in reducing agricultural accidents and fatalities. There is a growing interest in sociocultural approaches to OSH promotion amongst farmers, such as peer learning groups (PLGs). The level of OSH engagement within farmer PLGs (e.g. dairy discussion groups (DDGs)) is unknown. This study evaluates Irish DDG engagement with OSH in 2016 to better understand how DDGs contribute to OSH promotion. Methods: A mixed-mode (online, postal, and telephone) retrospective survey of 121 DDG representatives (i.e. chairperson or long-term member) assessed voluntary OSH engagement in 2016, including the location, frequency, duration, and content of OSH discussions. Results: Representatives of 96 DDGs participated in the survey and met the survey criteria. Most DDGs discussed OSH to some extent in 2016 (96%), including sharing personal experiences of accidents and illnesses (89%) and close calls (82%). For 76 DDGs, at least one meeting in 2016 addressed specific hazard and risk management topics. Groups were diverse with respect to discussion frequency, duration, and topics discussed. Conclusion: Farmers actively engaged with OSH in most DDGs surveyed, suggesting dairy farmers value OSH discussions. The findings illustrate the role of DDGs in OSH promotion, as a space for farmer-led, peer-to-peer knowledge-sharing. Farm advisory (extension) services and OSH professionals can strengthen OSH engagement through tailored resources that reflect contemporary OSH knowledge and popular discussion approaches (e.g. experience-sharing).

    Abstract Background: A study was initiated at Roswell Park Comprehensive Cancer Center to capture the real-world experience related to the use of CDK4/6 inhibitors (Ciclibs) for the treatment of metastatic hormone receptor-positive and HER2-negative breast cancer (HR+/HER2-).
    Patients and methods: A total of 222 patients were evaluated who received CDK4/6 inhibitors in the period from 2015 to 2021. Detailed clinical and demographic information was obtained on each patient and used to define clinical and demographic features associated with progression-free survival on CDK4/6 inhibitor-based therapies.
    Results: In this real-world analysis, the majority of patients received palbociclib as the CDK4/6 inhibitor with letrozole or fulvestrant as the predominant endocrine therapies. The median progression-free survival (PFS) in the letrozole (27.6 months) and fulvestrant (17.2 months) groups were comparable to that observed in clinical trials. As expected, age at start of the treatment and menopausal status influenced endocrine therapy utilization but were not associated with PFS. Patients with recurrent disease had shorter PFS (P = .0024) than those presenting with de novo metastasis. The presence of visceral metastasis trended toward shorter PFS (P = .051). Similarly, prior endocrine therapy (P = .003) or chemotherapy (P = .036) was associated with shorter PFS. Body mass index was not associated with PFS or with dose interruption and/or modification. While the number of minorities in this analysis is limited (n = 26), these patients as a group had statistically shorter PFS on treatment (P = .002).
    Conclusions: The real-world progression-free survival with CDK4/6 inhibitors mimics that observed in the clinical trial. A number of clinical and demographic features were associated with PFS on CDK4/6 inhibitor-based therapy. Further studies are ongoing to validate these findings incorporating additional cancer centers.

    Abstract Background: It is critically important to study the real-world data of FDA-approved medications to understand the response rates and toxicities observed in the real-world population not represented in the clinical trials.
    Methods: We reviewed charts of patients diagnosed with metastatic, hormone receptor-positive, human epidermal growth factor receptor 2 negative, PIK3CA-mutated breast cancer treated with alpelisib from May 2019 to January 2022. Clinical characteristics and treatment outcomes were collected. The association of clinical characteristics with responses and adverse events (AEs) was evaluated using the logistic regression model.
    Results: 27 patients were included. Median age at alpelisib initiation 67 years (range: 44, 77 years). Majority of patients had excellent performance status at time of alpelisib initiation. Most patients had chronic comorbidities, notably; 2 patients had controlled type 2 diabetes mellitus at time of alpelisib initiation. Majority had a median of three lines of therapy (range: 1, 7) before alpelisib. Clinical responses were determined using RECIST v1.1. 3/27 (11.11%) patients discontinued therapy before response assessment due to grade 3 AEs. Overall response rate was 12.5% (3/24), with all partial responses (PR). The median duration of response was 5.77 months (range: 5.54, 8.98). 14/27 (51.9%) of patients required dose interruption/reduction. Overall, 23/27 (85.19%) patients discontinued alpelisib of which 11 (47.83%) discontinued alpelisib due to AEs. Median duration of treatment was 2 months in patients who had grade 3 AEs (range: <1.00, 8.30) and 6.28 (1.15, 10.43) in those who did not. Any grade AEs were reported in 24/27 (88.9%) patients, namely, hyperglycemia 16/27 (59.3%), nausea 11/27 (40.7%), diarrhea 10/27 (37.0%), fatigue 7/27 (25.9%) and rash 6/27 (22.2%). Grade 3 AEs were reported in 13/27 patients (50%), namely, hyperglycemia in 7/27 (53.8%) patients followed by skin rash 4/27 (30.8%), GI side effects 3/27 (23.1%). Those with progressive disease as best response to alpelisib, had more non-metabolic comorbidities, higher number of liver metastases, PIK3CA E545K mutations, and shorter duration on therapy compared to those with PR and stable disease.
    Conclusion: Patients should be counseled about the toxicity and modest benefit observed with alpelisib in real-world clinical practice when used in later lines of therapy.
