Abstract
PURPOSE Antipsychotic use in Alzheimer disease (AD) is associated with adverse events and mortality. Whilst postulated to cause/exacerbate orthostatic hypotension (OH), the exact relationship between antipsychotic use and OH has never been explored in AD-a group who are particularly vulnerable to neuro-cardiovascular instability and adverse effects of medication on orthostatic blood pressure (BP) behaviour. METHODS We analysed longitudinal data from an 18-month trial of Nilvadipine in mild-moderate AD. We assessed the effect of long-term antipsychotic use (for the entire 18-month study duration) on orthostatic BP phenotypes measured on eight occasions, in addition to the relationship between antipsychotic use, BP phenotypes and incident falls. RESULTS Of 509 older adults with AD (aged 72.9 ± 8.3 years, 61.9% female), 10.6% (n = 54) were prescribed a long-term antipsychotic. Over 18 months, long-term antipsychotic use was associated with a greater likelihood of experiencing sit-to-stand OH (ssOH) (OR: 1.21; 1.05-1.38, p = 0.009) which persisted on covariate adjustment. Following adjustment for important clinical confounders, both antipsychotic use (IRR: 1.80, 1.11-2.92, p = 0.018) and ssOH (IRR: 1.44, 1.00-2.06, p = 0.048) were associated with a greater risk of falls/syncope over 18 months in older adults with mild-moderate AD. CONCLUSION Even in mild-to-moderate AD, long-term antipsychotic use was associated with ssOH. Both antipsychotic use and ssOH were associated with a greater risk of incident falls/syncope over 18 months. Further attention to optimal prescribing interventions in this cohort is warranted and may involve screening older adults with AD prescribed antipsychotics for both orthostatic symptoms and falls.

Abstract
Prenatal opioid exposure (POE) and postnatal adverse experiences are early life adversities (ELA) that often co-occur and increase problematic alcohol (EtOH) drinking during adolescence. We investigated the relationship between POE, postnatal adversity, and adolescent EtOH drinking in rats. We also sought to determine whether ELAs affect alpha-adrenoceptor density in the brain because the noradrenergic system is involved in problematic alcohol drinking and its treatment. We hypothesized that the combination of POE and postnatal adversity will increase alcohol drinking in rats compared to rats with exposure to either adversity alone or to control. We also predicted that POE and postnatal adversity would increase α1-adrenoceptor density and decrease α2-adrenoceptor density in brain to confer a stress-responsive phenotype. Pregnant rats received morphine (15 mg/kg/day) or saline via subcutaneous minipumps from gestational day 9 until birth. Limited bedding and nesting (LBN) procedures were introduced from postnatal day (PD) 3-11 to mimic early life adversity-scarcity. Offspring rats (PD 31-33) were given opportunities to drink EtOH (20 %, v/v) using intermittent-access, two-bottle choice (with water) procedures. Rats given access to EtOH were assigned into sub-groups that were injected with either yohimbine (1 mg/kg, ip) or vehicle (2 % DMSO, ip) 30 min prior to each EtOH access session to determine the effects of α2-adrenoceptor inhibition on alcohol drinking. We harvested cortices, brainstems, and hypothalami from EtOH-naïve littermates on either PD 30 or PD 70 and conducted radioligand receptor binding assays to quantify α1- and α2-adrenoceptor densities. Contrary to our hypothesis, only LBN alone increased EtOH intake in female adolescent rats compared to female rats with POE. Neither POE nor LBN affected α1- or α2-adrenoceptor densities in the cortex, brainstem, or hypothalamus of early- or late-aged adolescent rats. These results suggest a complex interaction between ELA type and sex on alcohol drinking.

Abstract
A modelling framework was developed to facilitate a probabilistic assessment of health risks posed by pesticide exposure via drinking water due to runoff, with the inclusion of influential site conditions and in-stream processes. A Monte-Carlo based approach was utilised to account for the inherent variability in pesticide and population properties, as well as site and climatic conditions. The framework presented in this study was developed with an ability to integrate different data sources and adapt the model for various scenarios and locations to meet the users' needs. The results from this model can be used by farm advisors and catchment managers to identify lower risk pesticides for use for given soil and site conditions and implement risk mitigation measures to protect water resources. Pesticide concentrations in surface water, and their risk of regulatory threshold exceedances, were simulated for fifteen pesticides in an Irish case study. The predicted concentrations in surface water were then used to quantify the level of health risk posed to Irish adults and children. The analysis indicated that herbicides triclopyr and MCPA occur in the greatest concentrations in surface water, while mecoprop was associated with the highest potential for health risks. The study found that the modelled pesticides posed little risk to human health under current application patterns and climatic conditions in Ireland using international acceptable intake values. A sensitivity study conducted examined the impact seasonal conditions, timing of application, and instream processes, have on the transport of pesticides to drinking water.

Abstract
Background Guidelines for anticoagulation management services recommend personnel be specially trained in warfarin management and suggest using tools such as decision-support software. To date, there have been no Canadian studies documenting the quality of warfarin management using a similar guideline recommended approach. Methods A cross-sectional, retrospective observational study was conducted to measure the quality of pharmacist-led warfarin management using point-of-care international normalized ratio (INR) testing and decision-support software in various ambulatory settings in Canada. Settings included 4 family health teams in Ontario and 40 community pharmacies across Nova Scotia. Quality was measured using time in therapeutic range (TTR) and was reported in 3 manners: mean TTR, median TTR and time-weighted mean TTR. Results The primary outcome included 963 patients. The combined mean and median TTR for the 2019 Ontario family health teams and Nova Scotia pharmacies was 74.2% and 77.3% (interquartile range 64%-87.9%), respectively. The time-weighted mean TTR was 76.3%. Discussion To the best of our knowledge, the TTR achieved by this model of care is the highest reported in Canadian general practice. Since Thrombosis Canada defines good-quality warfarin management as a TTR of 60% or greater, and many studies have reported an association between higher TTR values and lower rates of thrombosis and hemorrhage, this model of care may have significant benefits for patients. Conclusion This study demonstrates the high quality of anticoagulation management provided by specially trained pharmacists using point-of-care INR testing and decision-support software. These results support expanded access to this service for all Canadians. Can Pharm J (Ott) 2024;157:xx-xx.

Abstract
Cyclin-dependent kinase (CDK) 4/6 inhibition in combination with endocrine therapy is the standard-of-care treatment for patients with advanced-stage hormone receptor-positive, HER2 non-amplified (HR+HER2-) breast cancer. These agents can also be administered as adjuvant therapy to patients with higher-risk early stage disease. Nonetheless, the clinical success of these agents has created several challenges, such as how to address acquired resistance, identifying which patients are most likely to benefit from therapy prior to treatment, and understanding the optimal timing of administration and sequencing of these agents. In this Review, we describe the rationale for targeting CDK4/6 in patients with breast cancer, including a summary of updated clinical evidence and how this should inform clinical practice. We also discuss ongoing research efforts that are attempting to address the various challenges created by the widespread implementation of these agents.

Abstract
Alzheimer's Disease (ad) is the most common cause of dementia, and in addition to cognitive decline, it directly contributes to physical frailty, falls, incontinence, institutionalisation and polypharmacy in older adults. Increasing availability of clinically validated biomarkers including cerebrospinal fluid and positron emission tomography to assess both amyloid and tau pathology has led to a reconceptualisation of ad as a clinical-biological diagnosis, rather than one based purely on clinical phenotype. However, co-pathology is frequent in older adults which influence the accuracy of biomarker interpretation. Importantly, some older adults with positive amyloid or tau pathological biomarkers may never experience cognitive impairment or dementia. These strides towards achieving an accurate clinical-biological diagnosis are occurring alongside recent positive phase 3 trial results reporting statistically significant effects of anti-amyloid Disease-Modifying Therapies (DMTs) on disease severity in early ad. However, the real-world clinical benefit of these DMTs is not clear and concerns remain regarding how trial results will translate to real-world clinical populations, potential adverse effects (including amyloid-related imaging abnormalities), which can be severe and healthcare systems readiness to afford and deliver potential DMTs to appropriate populations. Here, we review recent advances in both clinical-biological diagnostic classification and future treatment in older adults living with ad. Advocating for access to both more accurate clinical-biological diagnosis and potential DMTs must be done so in a holistic and gerontologically attuned fashion, with geriatricians advocating for enhanced multi-component and multi-disciplinary care for all older adults with ad. This includes those across the ad severity spectrum including older adults potentially ineligible for emerging DMTs.

Abstract
AIMS To describe healthcare costs of patients with metastatic castration-resistant prostate cancer (mCRPC) initiating first-line (1 L) therapies from a US payer perspective. METHODS Patients initiating a Flatiron oncologist-defined 1 L mCRPC therapy (index date) on or after mCRPC diagnosis were identified from linked electronic medical records/claims data from the Flatiron Metastatic Prostate Cancer (PC) Core Registry and Komodo's Healthcare Map. Patients were excluded if they initiated a clinical trial drug in 1 L, had <12 months of insurance eligibility prior to index, or no claims in Komodo's Healthcare Map for the Flatiron oncologist-defined index therapy. All-cause and PC-related total costs per-patient-per-month (PPPM), including costs for services and procedures from medical claims (i.e. medical costs) and costs from pharmacy claims (i.e. pharmacy costs), were described in the 12-month baseline period before 1 L therapy initiation (including the baseline pre- and post- mCRPC progression periods) and during 1 L therapy (follow-up). RESULTS Among 459 patients with mCRPC (mean age 70 years, 57% White, 16% Black, 45% commercially-insured, 43% Medicare Advantage-insured, and 12% Medicaid-insured), average baseline all-cause total costs (PPPM) were $4,576 ($4,166 pre-mCRPC progression, $8,278 post-mCRPC progression). Average baseline PC-related total costs were $2,935 ($2,537 pre-mCRPC progression, $6,661 post-mCRPC progression). During an average 1 L duration of 8.5 months, mean total costs were $13,746 (all-cause) and $12,061 (PC-related) PPPM. The cost increase following 1 L therapy initiation was driven by higher PC-related outpatient and pharmacy costs. PC-related medical costs PPPM increased from $1,504 during baseline to $5,585 following 1 L mCRPC therapy initiation. LIMITATIONS All analyses were descriptive; statistical testing was not performed. CONCLUSION Incremental costs of progression to mCRPC are significant, with the majority of costs driven by higher PC-related costs. Using contemporary data, this study highlights the importance of utilizing effective therapies that slow progression and reduce healthcare resource demands despite the initial investment in treatment costs.

Abstract
Aim: To investigate real-world time to next treatment in patients with chronic lymphocytic leukemia initiating first-line (1L) ibrutinib or acalabrutinib. Materials & methods: US specialty pharmacy electronic medical records (21/11/2018-30/4/2022) were used; patients initiated 1L on/after 21/11/2019 (acalabrutinib approval). Results: Among 710 patients receiving ibrutinib, 5.9% initiated next treatment (mean time to initiation = 9.2 months); among 373 patients receiving acalabrutinib, 7.5% initiated next treatment (mean time to initiation = 5.9 months). Adjusting for baseline characteristics, acalabrutinib-treated patients were 89% more likely to initiate next treatment (hazard ratio = 1.89; p = 0.016). Conclusion: This study addresses a need for real-world comparative effectiveness between 1L ibrutinib and acalabrutinib and shows that next treatment (a clinically meaningful measure for real-world progression) occurred less frequently with 1L ibrutinib.

Abstract
AIMS To assess US payers' per-patient cost of testing associated with next-generation sequencing (NGS) versus polymerase chain reaction (PCR) biomarker testing strategies among patients with metastatic non-small cell lung cancer (mNSCLC), including costs of testing, delayed care, and suboptimal treatment initiation. METHODS A decision tree model considered biomarker testing for genomic alterations using either NGS, sequential PCR testing, or hotspot panel PCR testing. Literature-based model inputs included time-to-test results, costs for testing/medical care, costs of delaying care, costs of immunotherapy [IO]/chemotherapy [CTX] initiation prior to receiving test results, and costs of suboptimal treatment initiation after test results (i.e. costs of first-line IO/CTX in patients with actionable mutations that were undetected by PCR that would have been identified with NGS). The proportion of patients testing positive for a targetable alteration, time to appropriate therapy initiation, and per-patient costs were estimated for NGS and PCR strategies combined. RESULTS In a modeled cohort of 1,000,000 members (25% Medicare, 75% commercial), an estimated 1,119 had mNSCLC and received testing. The proportion of patients testing positive for a targetable alteration was 45.9% for NGS and 40.0% for PCR testing. Mean per-patient costs were lowest for NGS ($8,866) compared to PCR ($18,246), with lower delayed care costs of $1,301 for NGS compared to $3,228 for PCR, and lower costs of IO/CTX initiation prior to receiving test results (NGS: $2,298; PCR:$5,991). Cost savings, reaching $10,496,220 at the 1,000,000-member plan level, were driven by more rapid treatment with appropriate therapy for patients tested with NGS (2.1 weeks) compared to PCR strategies (5.2 weeks). LIMITATIONS Model inputs/assumptions were based on published literature or expert opinion. CONCLUSIONS NGS testing was associated with greater cost savings versus PCR, driven by more rapid results, shorter time to appropriate therapy initiation, and minimized use of inappropriate therapies while awaiting and after test results.

Abstract
AIMS To describe healthcare resource utilization (HRU) and costs of patients with metastatic castration-sensitive prostate cancer (mCSPC). METHODS Linked data from Flatiron Metastatic PC Core Registry and Komodo's Healthcare Map were evaluated (01/2016-12/2021). Patients with chart-confirmed diagnoses for metastatic PC without confirmed castration resistance in Flatiron who initiated androgen deprivation therapy (ADT) monotherapy or advanced therapy for mCSPC in 2017 or later (index date) with a corresponding pharmacy or medical claim in Komodo Health were included. Advanced therapies considered were androgen-receptor signaling inhibitors, chemotherapies, estrogens, immunotherapies, poly ADP-ribose polymerase inhibitors, and radiopharmaceuticals. Patients with <12 months of continuous insurance eligibility before index were excluded. Per-patient-per-month (PPPM) all-cause and PC-related HRU and costs (medical and pharmacy; from a payer's perspective in 2022 $USD) were described in the 12-month baseline period and follow-up period (from the index date to castration resistance, end of continuous insurance eligibility, end of data availability, or death). RESULTS Of 871 patients included (mean age: 70.6 years), 52% initiated ADT monotherapy as their index treatment without documented advanced therapy use. During baseline, 31% of patients had a PC-related inpatient admission and 94% had a PC-related outpatient visit; mean all-cause costs were $2551 PPPM and PC-related costs were $839 PPPM with $787 PPPM attributable to medical costs. Patients had a mean follow-up of 15 months, during which 38% had a PC-related inpatient admission and 98% had a PC-related outpatient visit; mean all-cause costs were $5950 PPPM with PC-related total costs of $4363 PPPM, including medical costs of $2012 PPPM. LIMITATIONS All analyses were descriptive; statistical testing was not performed. Treatment effectiveness and clinical outcomes were not assessed. CONCLUSION This real-world study demonstrated a significant economic burden in mCSPC patients, and a propensity to use ADT monotherapy in clinical practice despite the availability and guideline recommendations of advanced life-prolonging therapies.

Abstract
INTRODUCTION Alzheimer's disease and other dementias affect >50 million individuals globally and are characterised by broad clinical and biological heterogeneity. Cohort and biobank studies have played a critical role in advancing the understanding of disease pathophysiology and in identifying novel diagnostic and treatment approaches. However, further discovery and validation cohorts are required to clarify the real-world utility of new biomarkers, facilitate research into the development of novel therapies and advance our understanding of the clinical heterogeneity and pathobiology of neurodegenerative diseases. METHODS AND ANALYSIS The Tallaght University Hospital Institute for Memory and Cognition Biobank for Research in Ageing and Neurodegeneration (TIMC-BRAiN) will recruit 1000 individuals over 5 years. Participants, who are undergoing diagnostic workup in the TIMC Memory Assessment and Support Service (TIMC-MASS), will opt to donate clinical data and biological samples to a biobank. All participants will complete a detailed clinical, neuropsychological and dementia severity assessment (including Addenbrooke's Cognitive Assessment, Repeatable Battery for Assessment of Neuropsychological Status, Clinical Dementia Rating Scale). Participants undergoing venepuncture/lumbar puncture as part of the clinical workup will be offered the opportunity to donate additional blood (serum/plasma/whole blood) and cerebrospinal fluid samples for longitudinal storage in the TIMC-BRAiN biobank. Participants are followed at 18-month intervals for repeat clinical and cognitive assessments. Anonymised clinical data and biological samples will be stored securely in a central repository and used to facilitate future studies concerned with advancing the diagnosis and treatment of neurodegenerative diseases. ETHICS AND DISSEMINATION Ethical approval has been granted by the St. James's Hospital/Tallaght University Hospital Joint Research Ethics Committee (Project ID: 2159), which operates in compliance with the European Communities (Clinical Trials on Medicinal Products for Human Use) Regulations 2004 and ICH Good Clinical Practice Guidelines. Findings using TIMC-BRAiN will be published in a timely and open-access fashion.

Abstract
BACKGROUND Patient affordability is an important nonclinical consideration for treatment access among patients with schizophrenia. OBJECTIVE This study evaluated and measured out-of-pocket (OOP) costs for antipsychotics (APs) among Medicaid beneficiaries with schizophrenia. METHODS Adults with a schizophrenia diagnosis, ≥ 1 AP claim, and continuous Medicaid eligibility were identified in the MarketScan® Medicaid Database (1 January 2018-31 December 2018). OOP AP pharmacy costs ($US 2019) were normalized for a 30-day supply. Results were descriptively reported by route of administration [ROA; orals (OAPs), long-acting injectables (LAIs)], generic/branded status within ROAs, and dosing schedule within LAIs. The proportion of total (pharmacy and medical) OOP costs AP-attributable was described. RESULTS In 2018, 48,656 Medicaid beneficiaries with schizophrenia were identified (mean age 46.7 years, 41.1% female, 43.4% Black). Mean annual total OOP costs were $59.97, $6.65 of which was AP attributable. Overall, 39.2%, 38.3%, and 42.3% of beneficiaries with a corresponding claim had OOP costs > $0 for any AP, OAP, and LAI, respectively. Mean OOP costs per patient per 30-day claim (PPPC) were $0.64 for OAPs and $0.86 for LAIs. By LAI dosing schedule, mean OOP costs PPPC were $0.95, $0.90, $0.57, and $0.39 for twice-monthly, monthly, once-every-2-months, and once-every-3-months LAIs, respectively. Across ROAs and generic/branded status, projected OOP AP costs per-patient-per-year for beneficiaries assumed fully adherent ranged from $4.52 to $13.70, representing < 25% of total OOP costs. CONCLUSION OOP AP costs for Medicaid beneficiaries represented a small fraction of total OOP costs. LAIs with longer dosing schedules had numerically lower mean OOP costs, which were lowest for once-every-3-months LAIs among all APs.

Abstract
Purpose Increased dosing frequency adversely affects treatment adherence and outcomes in chronic diseases; however, such data related to treatment adherence is lacking in chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). This study compared adherence between patients treated with ibrutinib (once-daily) versus acalabrutinib (twice-daily) as first-line (1L) therapy for CLL/SLL. Patients and Methods Specialty pharmacy electronic medical records were used to identify adults with CLL/SLL initiating 1L ibrutinib or acalabrutinib between 01/01/2018 and 11/30/2020. Adherence was measured by the proportion of days covered (PDC) and medication possession ratio (MPR) and was compared between cohorts using odds ratios (ORs) obtained from logistic regression models adjusted for baseline characteristics. Results Between 01/01/2018 and 11/30/2020, 1374 and 140 patients initiated ibrutinib and acalabrutinib, respectively. Based on PDC/MPR ≥80%, patients treated with once-daily ibrutinib were more likely to be adherent than those treated with twice-daily acalabrutinib (OR ranges: PDC: 1.04-1.76; MPR: 1.03-1.58). At 6 months, patients on ibrutinib had a 58-76% higher likelihood of staying adherent compared to patients on acalabrutinib (PDC: 75.9% for ibrutinib vs 63.6% for acalabrutinib, OR: 1.76, P=0.008; MPR: 76.8% vs 66.9%, OR: 1.58, P=0.036) with a similar trend noted for the entire line of treatment (LOT) (PDC: 53.0% vs 41.4%, OR: 1.53, P=0.021; MPR: 58.7% vs 47.1%, OR: 1.50, P=0.027). Conclusion In this real-world analysis, CLL/SLL patients initiating 1L once-daily ibrutinib had >50% higher treatment adherence than those initiating twice-daily acalabrutinib during their LOT. Given the importance of sustained adherence for disease control in CLL/SLL, dosing frequency may be an important consideration for patients and physicians.

Abstract
BACKGROUND Maintaining continuity of care after schizophrenia-related hospitalization is challenging for patients and healthcare providers and systems. Prior evidence suggests that second-generation long-acting injectable antipsychotics (SGLAIs) may reduce the risk of treatment nonadherence and readmission versus oral atypical antipsychotics (OAAs). Therefore, quality measures were compared between patients initiated on SGLAIs and OAAs in the United States. METHODS Adults newly initiated on an SGLAI or OAA during a schizophrenia-related inpatient stay were identified in HealthVerity databases (01/2015-12/2020); the index date was the hospital discharge date. Patients had continuous health insurance coverage for pharmacy and medical services for 6 months pre-admission and post-discharge from the inpatient stay and ≥1 pharmacy or medical claim (i.e. treatment as indicated by the observed insurance claims) for an antipsychotic other than the index SGLAI or OAA in the 6 months pre-admission. Antipsychotic use and adherence, and schizophrenia-related readmissions and outpatient visits were compared during the 6-month period post-discharge. Characteristics between cohorts were balanced using inverse probability weights. RESULTS Post-discharge, only 36.9% and 40.7% of weighted SGLAI (N = 466) and OAA (N = 517) patients had ≥1 pharmacy or medical claim for the antipsychotic initiated during the inpatient stay, among whom SGLAI patients were 4.4 times more likely to be adherent to that antipsychotic compared to OAA patients (p < .001). Additionally, SGLAI patients were 2.3 and 3.0 times more likely to have a pharmacy or medical claim for and be adherent to any antipsychotic relative to OAA patients (including index antipsychotic; all p < .001). Within 7 and 30 days post-discharge, 1.7% and 13.0% of SGLAI patients and 4.1% and 12.6% of OAA patients had a readmission. Further, SGLAI patients were 51% more likely to have an outpatient visit compared to OAA patients (p = .044). CONCLUSIONS Less than half of patients initiated on antipsychotics during a schizophrenia-related inpatient stay continued the same treatment post-discharge. However, SGLAI patients were more likely to be adherent to the initiated antipsychotic and to have an outpatient visit, which may suggest improved continuity of care post-discharge relative to OAA patients.

Abstract
Until recently, despite its heterogenous biology, metastatic triple negative breast cancer (TNBC) was treated as a single entity, with successive lines of palliative chemotherapy being the only systemic option. Significant gene expression studies have demonstrated the diversity of TNBC, but effective differential targeting of the four main (Basal-like 1 and 2, mesenchymal and luminal androgen receptor) molecular sub-types has largely eluded researchers. The introduction of immunotherapy, currently useful only for patients with PD-L1 positive cancers, led to the stratification of first-line therapy using this immunohistochemical biomarker. Germline BRCA gene mutations can also be targeted with PARP inhibitors in both the adjuvant and metastatic settings. In contrast, the benefit of the anti-Trop-2 antibody-drug conjugate (ADC) Sacituzumab govitecan (SG) does not appear confined to patients with tumours expressing high levels of Trop-2, leading to its potential utility for any patient with an estrogen receptor (ER)-negative, HER2-negative advanced breast cancer (ABC). Most recently, low levels of HER2 expression, detected in up to 60% of TNBC, predicts benefit from the potent HER2-directed antibody-drug conjugate trastuzumab deruxtecan (T-DXd), defining an additional treatment option for this sub-group. Regrettably, despite recent advances, the median survival of TNBC continues to lag far behind the approximately 5 years now expected for patients with ER-positive or HER2-positive breast cancers. We review the data supporting immunotherapy, ADCs, and targeted agents in subgroups of patients with TNBC, and current clinical trials that may pave the way to further advances in this challenging disease.

Abstract
Pesticides are widely used in agriculture to optimise food production. However, the movement of pesticides into water bodies negatively impacts aquatic environments. The European Union (EU) aims to make food systems fair, healthy and environmentally friendly through its current Farm to Fork strategy. As part of this strategy, the EU plans to reduce the overall use and risk of chemical pesticides by 50 % by 2030. The attainment of this target may be compromised by the prevalence of legacy pesticides arising from historical applications to land, which can persist in the environment for several decades. The current EU Farm to Fork policy overlooks the potential challenges of legacy pesticides and requirements for their remediation. In this review, the current knowledge regarding pesticide use in Europe, as well as pathways of pesticide movement to waterways, are investigated. The issues of legacy pesticides, including exceedances, are examined, and existing and emerging methods of pesticide remediation, particularly of legacy pesticides, are discussed. The fact that some legacy pesticides can be detected in water samples, more than twenty-five years after they were prohibited, highlights the need for improved EU strategies and policies aimed at targeting legacy pesticides in order to meet future targets.

Abstract
BACKGROUND Increasing physical activity in people with Cystic Fibrosis (pwCF) can positively influence their physical and mental wellbeing. Online activities provide opportunity for outpatient CF populations to enhance physical activity. METHODS PwCF within a large Scottish CF unit were invited to participate in a pilot study of online exercise and education sessions. Those participating shared opinions on motivation, fitness habits, types of activities enjoyed pre and during shielding, and desirable goals for online activity. Subsequently, an online activity timetable was created offering daily exercise classes. Educational presentations driven by patient request were delivered in context appropriate to health, wellbeing, and infection control needs during the pandemic and the advent of modulator therapies. Twenty-eight group exercise sessions and 12 educational sessions occurred over the six-week pilot, following which, a post-pilot questionnaire was sent to those who had participated in the sessions. Risk assessment and exercise modifications ensured safe practice and accommodation for all levels of respiratory disease. RESULTS Twenty-six pwCF attended one or more exercise sessions and 37 pwCF attended one or more education sessions. Group exercise and education improved time efficiency compared to in-person face-to-face delivery. The post-pilot questionnaire demonstrated increases in motivation and perceived fitness, with positive comments regarding peer support and enhanced socialization. Personal fitness goals were fully or partially achieved by 91% of participants. CONCLUSION Patient feedback suggested the implementation of online exercise and education sessions for pwCF was a satisfactory and convenient way to deliver exercise allowing for optimization and progression of personal goals.

Abstract
470 Background: Intravesical BCG is considered a first-line (1L) treatment for high-risk NMIBC patients. Since the presence of carcinoma in situ (CIS) in NMIBC is associated with increased disease progression rates and poor clinical outcomes, BCG is prioritized in clinical guidelines for NMIBC patients with CIS. However, BCG’s US shortage may negatively affect clinical outcomes in patients. This study evaluated the adequacy of BCG treatment patterns among NMIBC patients, including a subgroup with CIS. Methods: Adults with NMIBC treated with BCG were selected from de-identified IBM MarketScan Commercial, Medicare, and Medicaid Databases (1/1/2010-2/28/2021). Treatment patterns were assessed from the first BCG claim (triggering the start of 1L treatment) until the end of the patient’s observation. Consistent with real-world literature, adequate BCG induction was defined as ≥5 BCG claims within 70 days of the first BCG claim whereas adequate BCG induction and maintenance was defined as ≥7 BCG claims within 274 days of the first BCG claim. Proportions of patients with adequate BCG induction and maintenance were compared between CIS subgroup and overall NMIBC cohorts using chi square tests. Results: Of 5,803 NMIBC patients treated with 1L BCG, 1,182 (20.4%) had documentation of CIS. Overall and CIS cohorts had similar mean age (67 years; range 18-101 years). After 1L BCG, 56.6% and 71.8% of the overall and CIS cohorts had another treatment (P<.001; table). While 86.9% and 90.0% of the overall and CIS cohorts had adequate BCG induction (P=0.003), only 41.5% and 50.8% had adequate BCG maintenance (P<.001). More patients in the CIS versus overall cohort had a cystectomy (13.9% vs 9.7%; P<.001). Conclusions: In this study, most NMIBC patients treated with BCG received adequate induction; however, BCG maintenance was inadequate and most patients had another treatment following 1L BCG. Patients with CIS were more likely to have cystectomy after BCG, suggesting higher risk of progression in this subgroup. Results of this study further emphasize a need for additional available treatment options that are safe, efficacious, and tolerable. [Table: see text]

Abstract
80 Background: Several recurrent mutations that interfere with the HRR DNA damage signaling response pathway have been recently identified as novel biomarkers that may help optimize treatment for patients with mCRPC. There is limited real-world information on clinical outcomes, including TTNT and OS, among patients with mCRPC who initiate 1L, overall and by HRR mutation status in the United States. Methods: This study used the nationwide (de-identified) Flatiron Health – Foundation Medicine Inc. (FMI) Metastatic Prostate Cancer Clinico-Genomic Database (1/1/2011–12/31/2021). The de-identified data originated from approximately 280 US cancer clinics (~800 care sites). Patients who initiated 1L therapy (index date) on or after mCRPC diagnosis and had ≥1 HRR mutation test any time prior to or on the index date were included. Patients were excluded if they initiated a clinical trial drug in 1L or had <12 months of clinical activity before the index date. Patients were classified as HRR+ (i.e., ATM, BRCA1, BRCA2, BRIP1, CDK12, CHEK2, FANCA, PALB2) or HRR-. HRR+ pathogenic mutations were any qualifying short variant, copy number loss, or rearrangement mutations. For TTNT, patients were followed from index date until the earliest of 2L initiation (outcome), end of clinical activity (including death) or end of data availability. For OS, patients were followed from index date until the earliest of death (outcome), end of clinical activity, or end of data availability. For both outcomes, HRR- patients were censored at first HRR+ mutation test. TTNT and OS were reported overall and by baseline HRR status using Kaplan-Meier methods. Flatiron Health and FMI did not participate in data analyses. Results: A total of 1,150 tested patients with mCRPC who initiated 1L therapy were included (mean age 70 years, 68% white, 59% initiated 1L on or after 2019). Overall, 257 patients (22%) were HRR+ by 1L initiation, of which 82 (7% overall) had a BRCA1/2 mutation. Overall, enzalutamide (31%), abiraterone acetate (30%), and docetaxel (20%) were the most used medications in 1L. The median TTNT was 8.0 months, overall, and was numerically shorter for HRR+ (6.8 months) than HRR- (8.2 months). Overall, 2L initiation rates were 15% at 3 months (HRR+: 17%; HRR-: 15%), 38% at 6 months (HRR+: 45%; HRR-: 36%), and 64% at 12 months (HRR+: 69%; HRR-: 62%). The median OS time was 24.9 months, overall, and was numerically shorter for HRR+ (23.0 months) compared to HRR- (25.8 months) patients. Overall, survival rates were 91% at 6 months (HRR+: 93%; HRR-: 91%), 78% at 12 months (HRR+: 75%; HRR-: 79%), and 51% at 24 months (HRR+: 47%; HRR-: 53%). Conclusions: Patients with HRR+ mCRPC were observed to have shorter survival and progress more rapidly from 1L to 2L therapy than HRR- patients, suggesting greater unmet need in these patients.

Abstract
This study assessed the total costs of testing, including the estimated costs of delaying care, associated with next-generation sequencing (NGS) versus single-gene testing strategies among patients with newly diagnosed metastatic non-small cell lung cancer (mNSCLC) from a Canadian public payer perspective. A decision tree model considered testing for genomic alterations using tissue biopsy NGS or single-gene strategies following Canadian guideline recommendations. Inputs included prevalence of mNSCLC, the proportion that tested positive for each genomic alteration, rebiopsy rates, time to test results, testing/medical costs, and costs of delaying care based on literature, public data, and expert opinion. Among 1,000,000 hypothetical publicly insured adult Canadians (382 with mNSCLC), the proportion of patients that tested positive for a genomic alteration with an approved targeted therapy was 38.0% for NGS and 26.1% for single-gene strategies. The estimated mean time to appropriate targeted therapy initiation was 5.1 weeks for NGS and 9.2 weeks for single-gene strategies. Based on literature, each week of delayed care cost CAD 406, translating to total mean per-patient costs of CAD 3480 for NGS and CAD 5632 for single-gene strategies. NGS testing with mNSCLC in current Canadian practice resulted in more patients with an identified mutation, shorter time to appropriate targeted therapy initiation, and lower total testing costs compared to single-gene strategies.

Abstract
BACKGROUND: Among patients with schizophrenia, nonadherence to oral atypical antipsychotics (OAAs) leads to increased risk of relapses, which entails substantial economic burden. OBJECTIVE: To evaluate the impact on health care costs and relapse rates of switching patients with schizophrenia from OAAs to once-monthly paliperidone palmitate (PP1M), with subsequent transitions to once-every-3-months (PP3M) and once-every-6-months paliperidone palmitate (PP6M). METHODS: A 36-month Markov model was developed from a Medicaid payer's perspective. Two non-mutually exclusive subpopulations of adults with schizophrenia who were nonadherent to OAAs were considered: (1) recently relapsed and (2) young adults (aged 18-35). Patients were assumed nonadherent to OAAs until switching treatments, which was permissible multiple times during the 36-month period. Patients switching to PP1M could subsequently transition to PP3M and PP6M. Relapse rates were assumed consistent across treatments based on patients' adherence. Model inputs were literature based. PP6M transition rates were assumed similar to PP3M. Cost savings were reported at the plan level and per patient switched. RESULTS: In a hypothetical health plan of 1 million Medicaid beneficiaries, an estimated 10,053 adults with schizophrenia were nonadherent to OAAs, among whom 7,454 were recently relapsed and 4,002 were young adults. Switching 5% of recently relapsed adults (N = 373) from OAAs to PP1M prior to subsequent relapse resulted in 541 relapses avoided and plan-level savings of $8.2M after 3 years. Incorporating transitions to PP3M/PP6M increased net savings to $9.1M and 631 relapses were avoided. Among young adults, switching 5% (N = 200) from OAAs to PP1M saved $1.8M at the plan level with 178 relapses avoided after 3 years. Including transitions to PP3M/PP6M, 3-year plan-level savings were $2.0M with 223 relapses avoided. Per recently relapsed patient switched to PP1M, and subsequently to PP3M/PP6M, cumulative 3-year cost savings were $22,100 and $24,300, respectively. Among young adults, corresponding 3-year cost savings per patient were $8,900 and $9,800. CONCLUSIONS: Switching nonadherent patients from OAAs to PP1M results in substantial cost savings and reduces relapse rates. Incorporating transitions to PP3M/PP6M leads to incremental cost savings and additional relapses avoided.

Abstract
This study reports the kinetics and isotherms of the adsorption of five herbicides, MCPA, mecoprop-P, 2,4-D, fluroxypyr and triclopyr, from aqueous solutions onto a range of raw and pyrolysed waste materials originating from an industrial setting. The raw waste materials investigated demonstrated little capability for any herbicide adsorption. Granulated activated carbon (GAC) was capable of the best removal of the herbicides, with >95% removal observed. A first order kinetic model fitted the data best for GAC adsorption of 2,4-D, while a pseudo-first order model fitted the data best for GAC adsorption of fluroxypyr and triclopyr, indicating that adsorption was via physisorption. A pseudo-second order kinetic model fitted the GAC adsorption of MCPA and mecoprop-P, which is indicative of chemisorption. The adsorption of the herbicides in all cases was best described by the Freundlich model, indicating that adsorption occurred onto heterogeneous surfaces.

Abstract
Abstract
Background
The presence of Orthostatic Hypotension (OH) is known to be associated with an increased mortality risk. Previous Irish research has shown that elevated Body Mass Index (BMI) may be protective against OH, with overweight and obese patients having significantly smaller Systolic Blood Pressure (SBP) drops during Head-Up-Tilt (HUT) Testing.
Methods
Demographics, including age, height and weight, were obtained retrospectively from all head up tilt testing performed in a tertiary Irish hospital between 2000 and 2021. All incomplete records were excluded. A total of 4,717 patients were analysed. Linear regression models were used to examine the relationship between BMI and change in tilt SBP.
Results
2,089 males and 2,628 females over the age of 60 years old were examined. The mean age is 77 years ± 7.8 (S.D.), with majority (51.5%) of the cohort overweight or obese. 69.7% of individuals demonstrated OH. The mean change in tilt SBP was –7mmHg in the underweight and healthy weight group, and –10mmHg in the overweight or obese group. The linear regression model established that BMI significantly predicted a change in tilt SBP (beta=0.394, 95% CI: 0.235 to 0.554, p<0.001), but remains a poor predictive variable (R2=0.004) for this cohort. This correlation was similar for both genders (male: r=0.08, female: r=0.07).
Conclusion
Our findings confirmed a correlation between BMI and its predictive impact on OH in older adults. Future studies should explore targeted populations with multivariate analysis, taking into consideration age and gender, to reduce the heterogeneity of data.

Abstract
Abstract
Background
Hypertension is common amongst older adults in Ireland and is a major risk factor for both ischaemic and haemorrhagic stroke. Several studies have investigated the relationship between height and hypertension, however results have been inconsistent. In our Irish tertiary hospital patients undergoing tilt table testing have resting blood pressure measured prior to the test, and height recorded. Our aim was to assess whether there is a relationship between height and resting Systolic Blood Pressure (SBP) in patients aged over 60 years.
Methods
All tilt table test results between 2000 and 2021 in a single centre were reviewed retrospectively, collecting data on age, height and resting SBP. Any incomplete records were excluded, as were those from patients under 60 years old. Linear regression modelling was used to assess relationship between height and resting SBP.
Results
A total of 4,729 complete records were included for patients over 60 years old. 2630 (61.5%) of the patients were female. Mean age was 77 ± 7.8 years. 57.7% patients had either an elevated resting systolic and/or diastolic BP ≥130/80 and 28.4% ≥140/90. The linear regression model established that while height could be used to predict resting systolic blood pressure (beta=-0.166, 95% CI: –0.219 to –0.113, p<0.001), height only accounted for 0.8% of variability in resting SBP (R2 = 0.008).
Conclusion
Our large dataset establishes an association but no meaningful causation between height and resting systolic blood pressure. Current antihypertensive treatment was not recorded, which may have affected the results. Future studies will include further multivariate analysis accounting for antihypertensive use and other factors that may impact hypertension such as age, weight and gender.

Abstract
Background/Aim: The occurrence of germ cell tumour (GCT) in the elderly is rare, with scarce data available. The aim of this study was to understand the clinical outcomes of patients with GCT in patients aged > 45 years. Materials and Methods: A retrospective study was conducted in a large tertiary cancer centre in north-west London. Between 1 January 2003 and 31 March 2022, 108 cases of GCT in men aged > 45 years were identified and treated at the Mount Vernon Cancer Centre. The median age at diagnosis was 54 years (range = 45−70 years). Results: The 5-year survival rate of all patients was 96%, and the toxicity profile was similar to the younger age group. Conclusion: Older patients with GCT are able to tolerate chemotherapy; however, care must be taken to prevent life-threatening complications using appropriate dose modification.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
This paper presents a novel scoring system which facilitates a relative ranking of pesticide risk to human health arising from contaminated drinking water. This method was developed to identify risky pesticides to better inform monitoring programmes and risk assessments. Potential risk was assessed considering pesticide use, chronic human health effects and environmental fate. Site-specific soil conditions, such as soil erodibility, hydrologic group, soil depth, clay, sand, silt, and organic carbon content of soil, were incorporated to demonstrate how pesticide fate can be influenced by the areas in which they are used. The indices of quantity of use, consequence and likelihood of exposure, hazard score and quantity-weighted hazard score were used to describe the level of concern that should be attributed to a pesticide. Metabolite toxicity and persistence were also considered in a separate scoring to highlight the contribution metabolites make to overall pesticide risk. This study presents two sets of results for 63 pesticides in an Irish case study, (1) risk scores calculated for the parent compounds only and (2) a combined pesticide-metabolite risk score. In both cases the results are assessed for two locations with differing soil and hydrological properties. The method developed in this paper can be adapted by pesticide users to assess and compare pesticide risk at site level using pesticide hazard scores. Farm advisors, water quality monitors, and catchment managers can apply this method to screen pesticides for human health risk at a regional or national level.

Abstract
Objective: Suicidal ideation or behavior (SIB) is a symptom of major depressive disorder (MDD). This study evaluated health care resource utilization (HRU) and costs of commercially insured adults who had diagnosed MDD with acute SIB (MDSI). Methods: Adults with MDSI (index date: first SIB claim) and controls without MDD or suicide-related claims (random index date) were identified using International Classification of Diseases, Clinical Modification, 10th Revision codes in the OptumHealth Care Solutions, Inc. database (October 2014 to March 2017). Adults with < 12 months of plan enrollment pre-index and/or selected psychiatric comorbidities were excluded. MDSI and control cohorts were matched 1:1 on demographics and comorbidities. HRU and costs were compared between matched cohorts during up to 1 and 12 months post-index (inclusive) using regressions adjusted for baseline costs. Results: Among patients with MDSI (n = 1,576, mean age = 34 years, 55.6% female), most index events occurred in emergency department (ED; 50.7%) and inpatient (45.2%) settings. The MDSI cohort, compared with the control cohort within 1 and 12 months post-index, respectively, had 157.7 and 28.0 times more inpatient admissions, 16.4 and 5.4 times more ED visits, and 4.9 and 3.2 times more outpatient visits (all P < .01). Incremental health care costs per patient per month in the MDSI compared with the control cohort within 1 and 12 months were $7,839 and $2,757, respectively (both P values < .01). Inpatient and ED costs constituted 70.6% and 16.5% of the total incremental costs, respectively, within the first month of follow-up. Conclusions: Among commercially insured adults, MDSI was associated with significant economic burden; inpatient and ED services drove incremental costs of the condition. Further assessment of treatment options for this vulnerable patient population is warranted.

Abstract
Introduction Biologics are a standard therapy for patients with moderate-to-severe psoriasis, yet treatment persistence is essential to achieve disease control. Compared with other biologics, ustekinumab has been associated with lower rates of discontinuation and better adherence among patients with psoriasis, but prior studies have included limited data from the period after approval of self-administration for ustekinumab. This study was conducted to assess discontinuation risk among patients with plaque psoriasis initiating ustekinumab or other biologics. Methods Adults with psoriasis and one or more claim for ustekinumab, secukinumab, adalimumab, or ixekizumab were identified in Optum’s de-identified Clinformatics Data Mart Database (1 January 2010 to 30 June 2019). Treatment discontinuation was defined as a gap in days of therapy supply based on (1) each drug’s per-label frequency of administration (main analysis) or (2) > 90 days (sensitivity analysis). Differences in baseline characteristics between the ustekinumab and other cohorts were adjusted with entropy balancing. Risk of discontinuation was compared with Cox proportional hazard models. Results Overall, 2230 patients were included in the ustekinumab cohort, with 1807 in the secukinumab, 4483 in the adalimumab, and 535 in the ixekizumab cohorts (mean age 49.0 years, 49.3% female for all cohorts). In the main analysis, risk of discontinuation for the ustekinumab cohort was 62.2% lower than for adalimumab, 46.4% lower than for secukinumab, and 43.8% lower than for ixekizumab cohorts (all p < 0.001). Sensitivity analyses revealed no significant differences between the ustekinumab and other cohorts. Conclusions Patients with psoriasis initiating ustekinumab had lower risk of treatment discontinuation compared with other biologics when discontinuation was based on each drug’s per-label frequency of administration. This finding may help inform choice of biologic based on compliance. Supplementary Information The online version contains supplementary material available at 10.1007/s13555-022-00707-z.

Abstract
Abstract
Background Abemaciclib is approved in 1st and 2nd line for hormone receptor (HR)-positive HER2-negative advanced breast cancer (ABC). However, outcomes on this agent are unclear in the real world.We determined the safety and efficacy profile of abemaciclib across 15 institutions in the United Kingdom. Methods We retrospectively identified HR-positive, HER2-negative ABC patients who received abemaciclib between July 2018 and June 2020. Demographics, disease characteristics, prior treatments, blood tests, toxicities, treatment delays and responses were recorded. Simple statistics, Fisher’s exact test, chi-squared method and Cox regression were used as appropriate. Results 228 patients identified had median age of 64 (31-93). 172 (75.4%) were postmenopausal and 209 (91.7%) had ECOG Performance Status 0-1. 145 (63.6%) had visceral involvement and 44 (19.3%) only bone disease. Patients received a median 1 (range 0-7) prior lines of treatment and 0 (range 0-5) prior chemotherapy lines.148 patients (64.9%) experienced diarrhoea (grade ≥3 in 16 [7.0%]). 146 patients (64.0%) developed neutropenia (grade ≥3 in 40 [17.5%]). 5 experienced febrile neutropenia (2.2%). 32 patients (14.0%) required hospitalisation due to toxicity (diarrhoea in 9 [3.95%]).Dose reductions were required in 107 patients (46.9%), mainly due to diarrhoea (55 [24.1%]) and to 50mg BD in 30 patients (13.2%). Dose delays were in median 14 (range 2-118). Abemaciclib was discontinued in 121 patients (53.1%) due to disease progression in 61 (26.7%) and toxicity in 48 (21.0%) (diarrhoea in 16 [7.0%]).Abemaciclib produced clinical benefit rate of 82.8% and overall response rate of 47.2% in 163 patients assessed. Overall, median progression-free survival (PFS) was 6.4 months (95% confidence interval [CI] 4.4-7.8) and median overall survival (OS) was 8.8 months (95% CI 7.6-10.6). Conclusions This a large real-world analysis of the safety and efficacy of abemaciclib in combination with endocrine therapy for advanced HR-positive breast cancer. In this analysis, the rates of diarrhoea were lower compared with the pivotal trial data, while neutropenia was more frequent. Although the PFS outcomes were similar to those previously reported, median OS was worse in this cohort which may reflect the different population of patients included, who were older and had more frequent visceral involvement. The selection of patients suitable for abemaciclib is crucial to ensure adequate efficacy and safety outcomes in this setting.

Abstract
AIMS Provide the first national description across the US of variations in healthcare measures in 2018 among Medicaid beneficiaries with schizophrenia. MATERIALS AND METHODS Adult beneficiaries with ≥2 diagnoses for schizophrenia, and continuous enrollment with consistent geographical data in all of 2018 were identified from Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) data for 45 of 50 states. Antipsychotic (AP) utilization rates, including long-acting injectable APs (LAIs), quality metrics, and all-cause healthcare resource utilization and costs for claims submitted to Medicaid were reported nationally and by state. Pearson correlation evaluated associations between LAI utilization and total healthcare costs at state and county levels. RESULTS Across the US 688,437 patients with schizophrenia were identified. The AP utilization rate was 51% (state range: 24-77%), while the LAI utilization rate was 13% (range: 4-26%). The proportion of patients adherent to any AP was 56% (range: 19-73%). Within 30 days post-discharge from an inpatient admission, 22% (range: 8-58%) of patients had an outpatient visit, and 12% (range: 4-48%) had a readmission. The proportion of patients with ≥1 inpatient admission and ≥1 emergency room visit was 34% (range: 19-82%) and 45% (range: 20-70%). Per-patient-per-year total healthcare costs averaged $32,920 (range: $717-$93,972). At the county level, a weak negative correlation was observed between LAI utilization and total healthcare costs. LIMITATIONS This study included Medicaid beneficiaries enrolled with pharmacy and medical benefits, including beneficiaries dually eligible for Medicare; results cannot be generalized to the overall schizophrenia population or those with other payer coverage. CONCLUSIONS In 2018, half of beneficiaries with schizophrenia did not submit any claims for APs to Medicaid, nearly half had an emergency room visit, and one-third had an inpatient admission. Moreover, healthcare measures varied considerably across states. These findings may indicate unmet treatment needs for Medicaid beneficiaries with schizophrenia.

Abstract
BACKGROUND To assess the total cost of testing associated with next-generation sequencing (NGS) versus polymerase chain reaction (PCR) testing strategies among patients with metastatic non-small cell lung cancer (mNSCLC) from a Medicare and US commercial payer's perspective. MATERIALS AND METHODS A decision tree model considered testing for genomic alterations in EGFR, ALK, ROS1, BRAF, KRAS, MET, HER2, RET, NTRK1 among patients with newly diagnosed mNSCLC using (1) liquid or tissue biopsy NGS tests, (2) exclusionary mutation (KRAS) test followed by sequential PCR tests, (3) sequential PCR tests, or (4) hotspot panel PCR tests. The alteration test sequence followed clinical guideline recommendations. Inputs based on literature, expert opinion, or assumptions included prevalence of mNSCLC, proportion of patients using each testing strategy (50% NGS [90% tissue, 10% liquid], 10% exclusionary, 10% sequential, 30% hotspot), proportion testing positive for each genomic mutation, rebiopsy rates, and costs for testing and associated medical care. Time to appropriate targeted therapy initiation and total costs were calculated for NGS, each PCR testing strategy, and all PCR strategies combined. RESULTS Among a hypothetical plan of 1,000,000 members (75% commercial, 25% Medicare), 1,119 patients were estimated to have mNSCLC and be eligible for testing. Estimated mean time to appropriate targeted therapy was 2 weeks for NGS and 6 weeks for PCR (sequential: 9 weeks, exclusionary: 8 weeks, hotspot: 3 weeks). Mean per patient costs were $4,932 for NGS and $6,605 for PCR (exclusionary: $5,563, sequential: $6,263, hotspot: $7,066). Per patient costs were higher from a commercial perspective (NGS: $6,225; PCR: $8,430) relative to Medicare (NGS: $2,099; PCR: $2,646); nevertheless, NGS was the least costly testing strategy across plan types. CONCLUSION NGS was associated with the fastest time to appropriate targeted therapy initiation and lowest total cost of testing compared to PCR testing strategies for newly diagnosed patients with mNSCLC.

Abstract
Abstract
Background
It is estimated that up to 300,000 people in Ireland have osteoporosis, however it is a disease most commonly associated with women. Women aged over 50 years have a four times greater rate of osteoporosis and are twice as likely to have osteopenia as men.1 However the recognition and treatment of osteoporosis in men cannot be forgotten. The Irish Hip Fracture Database National Report 2019 showed that 31% of 3,701 hip fractures that year were in males. Hip fractures have been shown to result in higher overall mortality in men than in women.2
Methods
A retrospective observational study was carried out by analysing the reports of all dual-energy X-ray absorptiometry (DEXA) scans performed in a large university teaching hospital from January 1998 to August 2021, collecting data on gender, age, bone mineral density and osteoporosis risk factors.
Results
A total of 39,611 patients having their first DEXA scan in our hospital were included. 85.2% were female and 14.8% male. In all patients over 75 years, only 12.9% of all patients getting a first DEXA scan were male. Of all women who had DEXA scans, 29.1% were diagnosed with osteoporosis and 38.4% with osteopenia and in men 16.6% osteoporosis and 40.7% osteopenia.
Conclusion
Our results highlight that men have DEXA scans performed much less frequently than women. This is seen in all age groups, especially in patients over 75 years old. As in women, the prevalence of osteoporosis in men increases with age. This study demonstrates the importance of evaluating for and treating osteoporosis in men as well as women, as fragility fractures can cause significant mortality and morbidity in both genders.

Abstract
Microplastic deposition in marine sediments is a geographically widespread problem. This study examines microplastics in intertidal and subtidal sediments at 87 locations in habitats designated as Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) on the coastline of Ireland. Established methodological approaches including, organic matter digestion, density separation, particle extraction and polymer identification were applied. Microplastic abundance was closely related with distance from known sources and concentrations were greater in intertidal as opposed to subtidal sediments. Colourless, polyethylene fibres and polypropylene fragments were the most abundant MP recorded and finer grained sediments were shown to entrap more MPs than coarser sediments. The results demonstrate that an understanding of potential sources of pollution, sediment type and hydrodynamic conditions are very important in terms of MP abundance and distribution in marine sediments and also in terms of effective waste management strategies and policy aimed at reducing the global plastics problem.

Abstract
INTRODUCTION Pre-existing conditions relevant for adverse events (AE) and the potential for drug-drug interactions (DDIs) may limit safe pharmacotherapeutic augmentation options for patients with major depressive disorder (MDD). This concern may be heightened among patients with treatment-resistant depression (TRD), who often have comorbid medical disorders. METHODS Adults with MDD and ≥ 1 antidepressant claim within the first observed major depressive episode were identified in the MarketScan® Databases. Those initiating a new regimen after two regimens at adequate dose and duration were considered to have TRD. The index date was defined at TRD onset or on a random antidepressant claim among patients with non-TRD MDD. Pre-existing conditions 12 months pre-index and potential DDIs 3 months pre/post-index associated with specific non-antidepressant augmentation therapies, including atypical antipsychotics (APs), buspirone, psychostimulants, anticonvulsants, thyroid hormone, and lithium were compared between 1:1 matched TRD and non-TRD MDD cohorts. RESULTS Overall, 3414 patients with TRD and non-TRD MDD (mean age 39.7 years, 69% female) were matched. Relative to non-TRD MDD, patients with TRD had 33% higher likelihood of ≥ 1 pre-existing condition relevant for AEs listed in product labels of non-antidepressant augmentation therapies (p < 0.001). Patients with TRD vs. non-TRD MDD had 12.9 and 6.4 times higher likelihood of ≥ 2 and ≥ 3 DDIs, respectively, based on their medication regimen (all p < 0.001). CONCLUSION Pre-existing conditions relevant for listed AEs and potential DDIs limit safe augmentation options in MDD, particularly among patients with TRD. Payer prior authorization policies requiring several augmentation therapy trials to access novel treatments may complicate clinical management of this population.

Abstract
BACKGROUND AND OBJECTIVE Suicidal ideation or behavior are core symptoms of major depressive disorder (MDD). This study aimed to understand heterogeneity among patients with MDD and acute suicidal ideation or behavior. METHODS Adults with a diagnosis of MDD on the same day or 6 months before a claim for suicidal ideation or behavior (index date) were identified in the MarketScan® Databases (10/01/2014-04/30/2019). A mathematical algorithm was used to cluster patients on characteristics of care measured pre-index. Patient care pathways were described by cluster during the 12-month pre-index period and up to 12 months post-index. RESULTS Among 38,876 patients with MDD and acute suicidal ideation or behavior, three clusters were identified. Across clusters, pre-index exposure to mental healthcare was revealed as a key differentiator: Cluster 1 (N = 16,025) was least exposed, Cluster 2 (N = 5640) moderately exposed, and Cluster 3 (N = 17,211) most exposed. Patients whose MDD diagnosis was first observed during their index event comprised 86.0% and 72.8% of Clusters 1 and 2, respectively; in Cluster 3, all patients had an MDD diagnosis pre-index. Within 30 days post-index, in Clusters 1, 2, and 3, respectively, 79.3%, 85.2%, and 88.2% used mental health services, including outpatient visits for MDD. Within 12 months post-index, 61.5%, 91.5%, and 84.6% had one or more antidepressant claim, respectively. Per-patient index event costs averaged $5614, $6645, and $5853, respectively. CONCLUSIONS Patients with MDD and acute suicidal ideation or behavior least exposed to the healthcare system pre-index similarly received the least care post-index. An opportunity exists to optimize treatment and follow-up with mental health services.

Abstract
AIMS To compare adherence, rates of subsequent schizophrenia-related relapses, healthcare resource utilization, and healthcare costs among Medicaid beneficiaries with schizophrenia who initiated once-monthly paliperidone palmitate (PP1M) versus a new oral atypical antipsychotic (OAA) following a recent schizophrenia-related relapse. METHODS Six-state Medicaid data (01/2009-03/2018) were used to identify adults with schizophrenia initiated on PP1M or OAA (index date) within 30 days following a schizophrenia-related relapse (defined as a schizophrenia-related inpatient or emergency room visit). Patients were required to have 12 months of continuous eligibility before (baseline) and after (observation) the index date. Differences in baseline characteristics between PP1M and OAA patients were accounted for using 1:3 matching. RESULTS After matching, characteristics were well-balanced between PP1M (N=208, mean age=39 years, 35.6% female) and OAA patients (N=624, mean age=40 years, 34.6% female). During the 12-month observation period, the mean proportion of days covered for the index medication was 41.2% in the PP1M cohort and 34.7% in the OAA cohort (p=.008). Relative to the OAA cohort, PP1M patients were 33% (p=.013) less likely to have a subsequent relapse and had 29% (p=.004) fewer all-cause inpatient admissions per-patient-per-year (PPPY). Consequently, a significant mean reduction of $6273 in medical costs PPPY (p=.028) was observed, which fully offset the $4770 (p<.001) increase in pharmacy costs PPPY and resulted in a numerical but not statistically significant, decrease in total healthcare costs of $1503 PPPY (p=.621) relative to OAA patients. CONCLUSIONS Among patients with a recent schizophrenia-related relapse, PP1M was associated with a lower risk of subsequent relapse while remaining a cost neutral therapeutic option compared to OAAs.

Abstract
The gold standard for imaging the cerebral metabolic rate of oxygen (CMRO2) is positron emission tomography (PET); however, it is an invasive and complex procedure that also requires correction for recirculating 15O-H2O and the blood-borne activity. We propose a noninvasive reference-based hybrid PET/magnetic resonance imaging (MRI) method that uses functional MRI techniques to calibrate 15O-O2-PET data. Here, PET/MR imaging of oxidative metabolism (PMROx) was validated in an animal model by comparison to PET-alone measurements. Additionally, we investigated if the MRI-perfusion technique arterial spin labelling (ASL) could be used to further simplify PMROx by replacing 15O-H2O-PET, and if the PMROx was sensitive to anesthetics-induced changes in metabolism. Methods: 15O-H2O and 15O-O2 PET data were acquired in a hybrid PET/MR scanner (3 T Siemens Biograph mMR), together with simultaneous functional MRI (OxFlow and ASL), from juvenile pigs (n = 9). Animals were anesthetized with 3% isoflurane and 6 mL/kg/h propofol for the validation experiments and arterial sampling was performed for PET-alone measurements. PMROx estimates were obtained using whole-brain (WB) CMRO2 from OxFlow and local cerebral blood flow (CBF) from either noninvasive 15O-H2O-PET or ASL (PMROxASL). Changes in metabolism were investigated by increasing the propofol infusion to 20 mL/kg/h. Results: Good agreement and correlation were observed between regional CMRO2 measurements from PMROx and PET-alone. No significant differences were found between OxFlow and PET-only measurements of WB oxygen extraction fraction (0.30 ± 0.09 and 0.31 ± 0.09) and CBF (54.1 ± 16.7 and 56.6 ± 21.0 mL/100 g/min), or between PMROx and PET-only CMRO2 estimates (1.89 ± 0.16 and 1.81 ± 0.10 mLO2/100 g/min). Moreover, PMROx and PMROxASL were sensitive to propofol-induced reduction in CMRO2 Conclusion: This study provides initial validation of a noninvasive PET/MRI technique that circumvents many of the complexities of PET CMRO2 imaging. PMROx does not require arterial sampling and has the potential to reduce PET imaging to 15O-O2 only; however, future validation involving human participants are required.

Abstract
Background Insufficient cost data and limited capacity constrains the understanding of the actual resources required for effective TB control. This study used process maps and time-driven activity-based costing to document TB service delivery processes. The analysis identified the resources required to sustain TB services in Zimbabwe, as well as several opportunities for more effective and efficient use of available resources. Methods A multi-disciplinary team applied time-driven activity-based costing (TDABC) to develop process maps and measure the cost of clinical pathways used for Drug Susceptible TB (DS-TB) at urban polyclinics, rural district and provincial hospitals, and community based targeted screening for TB (Tas4TB). The team performed interviews and observations to collect data on the time taken by health care worker-patient pairs at every stage of the treatment pathway. The personnel’s practical capacity and capacity cost rates were calculated on five cost domains. An MS Excel model calculated diagnostic and treatment costs. Findings Twenty-five stages were identified in the TB care pathway across all health facilities except for community targeted screening for TB. Considerable variations were observed among the facilities in how health care professionals performed client registration, taking of vital signs, treatment follow-up, dispensing medicines and processing samples. The average cost per patient for the entire DS-TB care was USD324 with diagnosis costing USD69 and treatment costing USD255. The average cost for diagnosis and treatment was higher in clinics than in hospitals (USD392 versus USD256). Nurses in clinics were 1.6 time more expensive than in hospitals. The main cost components were personnel (USD130) and laboratory (USD119). Diagnostic cost in Tas4TB was twice that of health facility setting (USD153 vs USD69), with major cost drivers being demand creation (USD89) and sputum specimen transportation (USD5 vs USD3). Conclusion TDABC is a feasible and effective costing and management tool in low-resource settings. The TDABC process maps and treatment costs revealed several opportunities for innovative improvements in the NTP under public health programme settings. Re-engineering laboratory testing processes and synchronising TB treatment follow-up with antiretroviral treatments could produce better and more uniform TB treatments at significantly lower cost in Zimbabwe.

Abstract
Abstract
Introduction
Appetite loss in older people is common and associated with malnutrition, sarcopenia and frailty. Management of appetite loss may prevent these health burdens but currently no effective clinical interventions exist. This is partly due to lack of knowledge about influences on appetite perceived by older individuals. These views may provide novel avenues for intervention on appetite loss. Aim: To understand older individual’s perceptions of influences on appetite loss.
Method
Semi-structured qualitative interviews with men and women aged ≥65 years, living in their own home, were audio-recorded and transcribed. Reflexive thematic analysis, with inductive coding, generated themes with data examples.
Results
13 individuals (8/13 female, 4/13 living alone) were recruited. Accounts of influences on appetite were grouped into three themes: physical, psychological and external factors. The physical theme related to a physical state of ageing, using energy and being active, and physical symptoms, illness and treatment. The psychological theme explained the influence of mood or wellbeing, the appeal of food, and reward in the activity of cooking. External factors related to influences of other people, coping with life experiences and transitions, and perceptions of health. Influences were perceived to impact on appetite loss in distinct ways, via a physical feeling of fullness (physical theme), or creating a negative experience with food and eating (psychological and external themes). Individuals tended to have either a physical or psychological focus. Importantly, illness and its treatment impacted on both appetite loss narratives.
Conclusions
A number of influences on appetite are described by older individuals, relating to their physical and psychological self, and social and environmental factors. These seem to impact on appetite loss in distinct ways, by precipitating either a physical feeling of fullness, or a negative experience with food and eating. Identifying factors affecting an individual’s appetite could facilitate person-centred approaches to management.

Antipsychotic Adherence, Resource Use, and Costs Before and After the Initiation of Once-monthly Paliperidone Palmitate Therapy Among Medicaid Beneficiaries With Prior Schizophrenia Relapse.

Abstract
PURPOSE Patients with schizophrenia often struggle with medication adherence and may benefit from the use of a long-acting injectable antipsychotic, including once-monthly paliperidone palmitate (PP1M), which was previously demonstrated to improve outcomes compared with oral antipsychotics. This study assessed the impact of initiating PP1M therapy on medication adherence, health care resource use (HRU), and costs among Medicaid beneficiaries with schizophrenia and a prior schizophrenia relapse. METHODS A 6-state Medicaid database (from quarter 1 of 2009 to quarter 1 of 2018) was used to identify adults with ≥2 schizophrenia diagnoses who started PP1M therapy on or after January 1, 2010. The index date was the first PP1M claim. Patients had ≥12 months of continuous Medicaid enrollment before and after the index date, ≥1 oral antipsychotic claim in the 12 months before the index date, and ≥1 relapse (proxied as a schizophrenia-related inpatient admission or emergency department [ED] visit) during the 12 months before the index date. Generalized estimating equations were used to compare adherence to antipsychotics (proportion of days covered ≥80%), HRU, and costs (reported in 2018 US dollars) in the 12 months after versus before the index date. Sensitivity analyses were conducted (1) accounting for the minimum and cumulative price inflation Medicaid rebates for pharmacy costs of branded psychiatric medications, (2) among patients with ≥2, ≥3, and ≥4 prior schizophrenia-related inpatient admissions or ED visits, (3) among patients not adherent to antipsychotic treatment before the index date, and (4) among patients switching to PP1M directly from oral risperidone or paliperidone. FINDINGS A total of 1725 patients met the study inclusion criteria (mean age, 39.5 years; 43% female). After versus before the index date, patients were 93% more likely to be adherent to antipsychotic treatment (P < 0.01). The likelihood of inpatient admissions and ED visits decreased by 89% and 49% (all P < 0.01) after initiating PP1M therapy. The number of inpatient days decreased by 31% (P < 0.01) and the number of ED visits by 16% (P = 0.03). Pharmacy costs increased by $514 per-patient-per-month (PPPM), whereas medical costs, driven by inpatient costs, decreased by $391 PPPM (all P < 0.01). Sensitivity analyses yielded similar trends. Notably, total health care cost savings of $231 PPPM were observed after accounting for the cumulative Medicaid rebate for costs of branded psychiatric medications (P < 0.01). IMPLICATIONS In Medicaid beneficiaries with relapsed schizophrenia, transitioning from oral antipsychotics to PP1M was associated with improved adherence to antipsychotics and decreased use of inpatient and ED services. Increased pharmacy costs after the initiation of PP1M were offset by decreased medical costs. After applying the cumulative Medicaid rebate, including the price inflation rebate for costs of branded psychiatric medications, initiation of PP1M therapy resulted in statistically significant health care cost savings.

Abstract
OBJECTIVE To compare switching and discontinuation patterns of patients stable on originator infliximab (IFX) who switched to an IFX biosimilar (switchers) or remained on originator IFX (continuers) in the United States. METHODS Symphony Health Solutions' Patient Transactional Datasets (10/2012-03/2019) were used to identify adults with ≥2 claims for either rheumatoid arthritis (RA), psoriatic arthritis, plaque psoriasis, ankylosing spondylitis, or inflammatory bowel disease (IBD); and ≥1 claim for originator or biosimilar IFX. The index date was the first IFX biosimilar claim for switchers or a random originator IFX claim for continuers. All patients were required to have ≥5 originator IFX claims during the 12 months pre-index (prevalent population). The subset of patients with ≥12 months of observation prior to the first originator IFX claim was also analyzed (incident population). Switchers were matched 1:3 to continuers. Discontinuation was defined as having ≥120 days between 2 consecutive index treatment claims. RESULTS Prevalent switchers (N=1109) were 3.57-times more likely than continuers (N=3327) to switch to another originator biologic (hazard ratio [HR]=3.57, p<0.001). Of 249 prevalent switchers who switched to another originator biologic, 200 (80.3%) switched back to originator IFX. Incident switchers (N=571) were 2.55-times more likely than continuers (N=1713) to switch to another originator biologic (HR=2.55, p<0.001). Of 118 incident switchers who switched to another originator biologic, 90 (76.3%) switched back to originator IFX. Prevalent switchers were 1.25-times more likely than continuers to discontinue index therapy (HR=1.25, p<0.001). Similar results were observed in RA (prevalent population; switching: HR=3.49, p<0.001; discontinuation: HR=1.23, p=0.009) and IBD (prevalent population; switching: HR=3.82, p<0.001; discontinuation: HR=1.29, p=0.003) subgroups. CONCLUSION Patients switching from originator to biosimilar IFX were more likely to switch to another originator biologic (notably back to originator IFX) and discontinue index treatment than those remaining on originator IFX; however, reasons for switching are unknown.

Abstract
This is the first multimodal study of cerebral tissue metabolism and perfusion post-hypoxic-ischaemic (HI) brain injury using broadband near-infrared spectroscopy (bNIRS), diffuse correlation spectroscopy (DCS), positron emission tomography (PET) and magnetic resonance spectroscopy (MRS). In seven piglet preclinical models of neonatal HI, we measured cerebral tissue saturation (StO2), cerebral blood flow (CBF), cerebral oxygen metabolism (CMRO2), changes in the mitochondrial oxidation state of cytochrome c oxidase (oxCCO), cerebral glucose metabolism (CMRglc) and tissue biochemistry (Lac+Thr/tNAA). At baseline, the parameters measured in the piglets that experience HI (not controls) were 64 ± 6% StO2, 35 ± 11 ml/100 g/min CBF and 2.0 ± 0.4 μmol/100 g/min CMRO2. After HI, the parameters measured were 68 ± 6% StO2, 35 ± 6 ml/100 g/min CBF, 1.3 ± 0.1 μmol/100 g/min CMRO2, 0.4 ± 0.2 Lac+Thr/tNAA and 9.5 ± 2.0 CMRglc. This study demonstrates the capacity of a multimodal set-up to interrogate the pathophysiology of HIE using a combination of optical methods, MRS, and PET.
