Imaging platforms for generating highly multiplexed histological images are being continually developed and improved. Significant improvements have also been made in the accuracy of methods for automated cell segmentation and classification. However, less attention has focused on the quantification and analysis of the resulting point clouds, which describe the spatial coordinates of individual cells. We focus here on a particular spatial statistical method, the cross-pair correlation function (cross-PCF), which can identify positive and negative spatial correlation between cells across a range of length scales. However, limitations of the cross-PCF hinder its widespread application to multiplexed histology. For example, it can only consider relations between pairs of cells, and cells must be classified using discrete categorical labels (rather than labeling continuous labels such as stain intensity). In this paper, we present three extensions to the cross-PCF which address these limitations and permit more detailed analysis of multiplex images: topographical correlation maps can visualize local clustering and exclusion between cells; neighbourhood correlation functions can identify colocalization of two or more cell types; and weighted-PCFs describe spatial correlation between points with continuous (rather than discrete) labels. We apply the extended PCFs to synthetic and biological datasets in order to demonstrate the insight that they can generate.

Objective:
To explore the benefits and barriers of using an interactive robotic seal (PARO, Figure 1) based on the experiences of nursing home residents living with dementia and chronic pain, their family members, and formal caregivers.
Methods:Semi-structured interviews were conducted alongside a feasibility randomized controlled trial at one nursing home in Brisbane, Australia between July 2021 and January 2022 (Trial registration: ACTRN 12621000837820). Residents with dementia and chronic pain interacted with PARO individually for 15 min once or twice daily, five days per week for three consecutive weeks. After which, individual interviews were conducted with residents who were capable of communicating (n=13), family members (n=3), registered nurses (n=4), care assistants (n=11), a physical therapist (n=1), a diversional therapist (n=1) and the facility manager (n=1) who experienced or observed the residents’ interactions with PARO. The interviews were audio-recorded, transcribed, and analyzed using thematic analysis.
Results:Almost all participants reported that interacting with PARO benefited residents with dementia and their caregivers. These benefits included (1) reducing pain by providing distraction and stimulation; (2) reducing behavioral and psychological symptoms of dementia; (3) promoting positive emotions by recalling memories; and (4) reducing anxiety and care burden for family and formal caregivers. Neutral attitudes toward PARO were reported by three residents with mild cognitive impairment as they reported it did not make any difference. Barriers to using PARO included limited staff training and the implementation of person‐ centered care due to limited resources.
Conclusion:Overall, multiple stakeholders were positive about using PARO to reduce pain and behavioral symptoms of nursing home residents living with dementia and chronic pain. PARO may also reduce the care burden of family and formal caregivers. PARO might be incorporated into daily practice to support nursing home residents living with dementia. Improving staff training and understanding individual preferences of residents may enhance the implementation of PARO in this population.

Introduction
Decision-making for vaccination programs requires additional consideration on broader effects. The cost-effectiveness guidelines published by the Professional Society for Health Economics and Outcomes Research (ISPOR) working group recommends considering broader effects such as herd protection. Whilst difficulty to produce robust data for such factors might hinder quicker decisions, they are important features of vaccination programs and some of them were the narratives that dominated over the COVID-19 pandemic. In this systematic literature review, the perspectives taken and inclusion of broader effects were investigated for recent influenza vaccine economic evaluations.
MethodsThe search strategy based on the terms influenza vaccination and cost-effectiveness was carried out on Embase and PubMed. Considering the publication date of the ISPOR guidelines, articles since 2019 were searched. The review focus was the perspectives taken and inclusion of broader benefits in the analysis. A link between perspective and inclusion of broader effects was tested with a Chi-square test.
ResultsThe total number of full cost-effectiveness articles screened was 48. Of those, the number of articles performed from both the perspectives was 18 (37.5%), and 13 articles (27.1%) considered the perspective of payer only. For those that had both perspectives considered, the ICER reported from the societal perspective was consistently lower than that from the payer perspective. Thirty-one articles (65%) included any of the broader effects. However, broader effects considered were limited to indirect protection (17 articles, 35.4%) and productivity loss (22 articles, 45.8%). The relation between perspective and inclusion of broader effects was significant (p=0.04).
ConclusionsThis review highlights that studies performed using both payer and societal perspectives as recommended by the ISPOR research guidelines are not many, while more favorable outcomes were presented when the societal perspective was adapted. Broader effects included are productivity loss and indirect protection.
For other broader effects specified in the research guidelines, there are not many attempts to include those in economic evaluations.

Summary
Behavior change interventions have made an indelible mark on addressing problems that require behavioral solutions; however, such interventions also come at a financial cost. Identifying whether the benefits of behavioral changes are greater than the cost of the intervention itself, and the relative return on those costs compared to alternative opportunities, is critical to ensuring that behavior change interventions are truly beneficial and maximize the return on scarce resources. Cost-effectiveness analysis (CEA), as a form of economic evaluation that has been widely used, can provide evidence to inform decisions on whether funding bodies should fund these interventions or otherwise. The aim of this chapter is to outline the methods and approaches to CEA of behavior change interventions and discuss the role of economic evaluation in this setting. The chapter starts by presenting a framework for conducting economic evaluations of behavior change interventions. The framework sets out how to identify participants, interventions, comparators, and outcomes for economic evaluation studies. The chapter then outlines the appraisal of CEA by applying the consolidated health economic evaluation reporting standards checklist. Finally, the chapter discusses the implications and recommendations for CEA, including discussion of the appropriate measurement of benefits, feasible model approaches, and issues underlying political considerations when funding behavior change interventions.

Analysis of diatoms, pollen, and the carbon-isotopic composition of a sediment core from a brackish marsh in the northern part of the San Francisco Estuary has provided a paleosalinity record that covers the past 3000 yr. Changes in marsh composition and diatom frequencies are assumed to represent variations in freshwater inflow to the estuary. Three periods of relatively high salinity (low freshwater inflow) are indicated, 3000 to 2500 cal yr B.P., 1700 to 730 cal yr B.P., and ca. A.D. 1930 to the present. The most recent period of high salinity is primarily due to upstream storage and water diversion within the Sacramento–San Joaquin watershed, although drought may also have been a factor. The two earlier high-salinity periods are likely the result of reduced precipitation. Low salinity (high freshwater flow) is indicated for the period 750 cal yr B.P. to A.D. 1930.

Objectives: Made available since 2002, transcatheter aortic valve implantation (TAVI) is a minimally invasive new intervention which can provide significant survival improvement to patients with aortic stenosis. However, TAVI is expensive and currently not reimbursed by many governments. Some governments and institutions have been conducting health technology assessments (HTAs) to inform their reimbursement decisions. The aim of the present study is to review HTAs that have relied on a cost-effectiveness analysis to inform reimbursement decisions of TAVI.
Methods: A systematic literature review was conducted among published literature as well as reports released by HTA agencies. Predetermined inclusion and exclusion criteria, following the Preferred Reporting System for Systematic Reviews and Meta-Analysis guidelines, were used to select relevant HTAs. The selected papers were assessed against the Consolidated Health Economic Evaluation Reporting Standards.
Results: HTAs on TAVI from three countries were available for this review: Canada, Belgium, and the United Kingdom. All three HTAs used the Placement of Aortic Transcatheter Valve (PARTNER) trial data with Markov models to estimate the incremental cost effectiveness ratio. The three HTAs recommended conditional reimbursement for TAVI for otherwise inoperable patients. The HTAs did not use clear methods to estimate the health-related utility which ultimately affected their cost-effectiveness results. The UK HTA showed the best value for money (US$20,416 per quality-adjusted life-year).
Conclusion: All studies found TAVI to be more costly and less effective for high-risk patients suitable for surgery, whereas TAVI was consistently found to be cost effective for otherwise inoperable patients.
