Abstract	Scientists from nursing and allied health disciplines frequently examine data with complex distributions. Key examples include data on cost that typically are skewed, and count data like the number of hospitalizations that regularly have greater variation than expected and a majority of observations at zero. Common approaches to handling complex data involve transformations that can interfere with interpretation, or force-fitting of data into linear or logistic regression. In this article, worked examples of generalized linear models, which allow for flexibility in the distribution of data, involving cost and count outcomes, are presented to help expose researchers to their nuances.

Abstract	Aims: To determine if distinct trajectories of coronary heart disease (CHD) self-care behaviours could be identified, linked to differences in quality of life (QoL), and predicted based on baseline characteristics. Methods and results: A secondary analysis of a prospective, longitudinal, observational study. Patients with CHD answered questionnaires at study enrolment and six months later: Self-Care of Coronary Heart Disease Inventory (three subscales: maintenance, management and confidence, scored 0-100, higher score = better self-care), Hospital Anxiety and Depression Scale, 12-Item Short Form Survey, 16-Item European Health Literacy Survey Questionnaire, CHD Education Questionnaire. Latent growth mixture modelling was used to identify distinct self-care trajectories over time.On average, patients (n = 430, mean age 64.3 ± 8.9, 79% male) reported inadequate self-care (maintenance 61.6 ± 15.4, management 53.5 ± 18.5) at enrolment. Two distinct trajectories of self-care behaviours were identified: First, an "inadequate-and-worsening" (IN-WORSE) trajectory (57.2%), characterised by inadequate self-care, improvement in maintenance (4.0 ± 14.5-point improvement, p < 0.001) and worsening of management over time (6.3 ± 24.4-point worsening, p = 0.005). Second, an "inadequate-but-maintaining" (IN-MAIN) trajectory (42.8%), characterised by inadequate self-care, improvement in maintenance (5.0 ± 16.2-point improvement, p < 0.001) and stability in management over time (0.8 ± 21.9-point worsening, p = 0.713). In comparison, patients in the IN-WORSE trajectory had less favourable characteristics (including lower health literacy, knowledge, confidence) and significantly lower QoL. Not attending rehabilitation (OR 2.175; CI 1.020-4.637, p = 0.044) and older age (OR 0.959; CI 0.924-0.994, p = 0.024) predicted (IN-WORSE) trajectory inclusion. Conclusion: Two self-care trajectories were identified, both suboptimal. Rehabilitation predicted membership in the more favorable trajectory and some positive characteristics were identified among patients in that group. Therefore, interventions supporting these factors may benefit patients' self-care and QoL.

Article: Revision Medial Patellofemoral Ligament Reconstruction for Recurrent Instability After Patellofemoral Arthroplasty.

Abstract	Recurrent patellar instability is a rare complication after patellofemoral arthroplasty (PFA) and usually involves a traumatic injury. Medial patellofemoral ligament (MPFL) reconstruction after arthroplasty is a complicated and technically challenging surgical procedure because the lack of patellar bone stock due to resurfacing significantly increases the risk of patellar fracture. We present our surgical technique for revision MPFL reconstruction for recurrent instability after PFA. This technical note describes the use of 1.8-mm all-suture anchors for revision MPFL reconstruction in patients with decreased patellar bone stock after PFA. This technique reduces the risk of patellar fracture without compromising the integrity of the MPFL graft.

Abstract	Survival analysis, also called time-to-event analysis, is a common approach to handling event data in cardiovascular nursing and health-related research. Survival analysis is used to describe, explain, and/or predict the occurrence and timing of events. There is a specific language used and methods designed to handle the unique nature of event data. In this methods paper, we provide an 'easy start guide' to using survival analysis by (i) providing a step-by-step guide and (ii) applying the steps with example data. Specifically, we analyse cardiovascular event data over 6 months in a sample of patients with heart failure.

Abstract	Background: Chronic liver disease is a significant global neglected public health problem. End-stage liver disease is associated with substantial symptom complexity, disability, and care needs that require assistance from informal family care partners. Research on these care partners' caregiver burden or strain, symptoms, and quality of life is sparse and has not focused on these variables as co-occurring or in the context of the quality of the relationship care partners have with the patients. Objectives: The purpose of this study was to provide a collective presentation of patterns and determinants of well-being as measured by caregiver strain, depression, sleep, and quality of life in a cohort of informal family care partners for adult outpatients with end-stage liver disease. Methods: Care partners (age > 18 years) were recruited from two liver clinics within two tertiary health care systems and invited to complete a cross-sectional survey. They completed the Multidimensional Caregiver Strain Index, Patient Health Questionnaire, Pittsburgh Sleep Quality Index, Short Form Health Survey, and Mutuality Scale. Descriptive statistics and latent class mixture modeling were used to analyze these data. Results: The sample was predominantly female and White. The well-being of care partners was diminished. Three distinct classes of well-being were identified: mildly diminished (53.2%), moderately diminished (39.0%), and severely diminished (7.8%). Those at greater risk of worse well-being were younger, spouses, and had poorer relationship quality with the patients. Discussion: To improve the well-being of care partners in moderately and severely diminished classes, assessing and addressing caregiver strain and co-occurring symptoms is essential. Addressing this strain and symptoms has the potential to maintain or optimize care partners' ability to provide care to patients. Future researchers should include longitudinal and dyadic studies to examine how patients' disease progression and symptoms may affect family care partners well-being and vice versa.

Article ; Online: Person with Heart Failure and Care Partner Dyads: Current Knowledge, Challenges, and Future Directions: State-of-the-Art Review.

Abstract	Over the past decade, there has been substantial growth in heart failure (HF) research that focuses on persons with HF and their care partners (family members or other close friends that provide unpaid support) as an interdependent team, or care dyad. In this state-of-the-art review, we use a dyadic lens to identify and summarize current research on HF care dyads, from qualitative studies, to nonexperimental quantitative studies, to randomized controlled trials. Although much work has been done, this literature is younger and less well-developed than care dyad literatures from other conditions (eg, cancer, Alzheimer's disease). We discuss the substantial challenges and limitations in this body of work, with an eye toward addressing common issues that impact rigor. We also look toward future directions, and discuss the promise dyadic research holds for improving patient, care partner, and relationship health.

Abstract	There is a long tradition of incorporating patient-reported outcomes (PROs) into nursing research and practice. Classical Test Theory (CTT) has been the traditional approach used to develop and refine PROs. Item response theory (IRT) offers promise for addressing measurement problems that have been difficult to solve using CTT. This paper presents foundational concepts in IRT to illustrate how it can be used to improve the development and refinement of PRO measures, with emphasis on interpreting key IRT parameters.
