Objective: To investigate individual preferences for physical activity (PA) attributes in adults with chronic knee pain, to identify clusters of individuals with similar preferences, and to identify whether individuals in these clusters differ by their demographic and health characteristics. Design: An adaptive conjoint analysis (ACA) was conducted using the Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA) method to determine preference weights representing the relative importance of six PA attributes. Cluster analysis was performed to identify clusters of participants with similar weights. Chi-square and ANOVA were used to assess differences in individual characteristics by cluster. Multinomial logistic regression was used to assess associations between individual characteristics and cluster assignment.Results: The study sample included 146 participants; mean age 65, 72% female, 47% white, non-Hispanic. The six attributes (mean weights in parentheses) are: health benefit (0.26), enjoyment (0.24), convenience (0.16), financial cost (0.13), effort (0.11) and time cost (0.10). Three clusters were identified: Cluster 1 (n ¼ 33): for whom enjoyment (0.35) is twice as important as health benefit; Cluster 2 (n ¼ 63): for whom health benefit (0.38) is most important; and Cluster 3 (n ¼ 50): for whom cost (0.18), effort (0.18), health benefit (0.17) and enjoyment (0.18) are equally important. Cluster 1 was healthiest, Cluster 2 most self-efficacious, and Cluster 3 was in poorest health. Conclusions: Patients with chronic knee pain have preferences for PA that can be distinguished effectively using ACA methods. Adults with chronic knee pain, clustered by PA preferences, share distinguishing characteristics. Understanding preferences may help clinicians and researchers to better tailor PA interventions.

Liver transplant recipients (LTRs) are at high risk for cardiovascular disease (CVD). We sought to characterize LTR, informal caregiver, and health care provider perceptions about CVD care after liver transplantation (LT) to inform the design of solutions to improve care. Participants included adult LTRs, their caregivers, and multispecialty health care providers recruited from an urban tertiary care network who participated in 90-minute focus groups and completed a brief survey. Focus group transcripts were analyzed using thematic analysis, and survey data were analyzed using descriptive statistics. A total of 17 LTRs, 9 caregivers, and 22 providers participated in 7 separate focus groups. Most (93.3%) LTRs and caregivers were unaware of the risk of CVD after LT. Although 54.5% of providers were confident discussing CVD risk factors with LTRs, only 36.3% were confident managing CVD risk factors in LTRs, and only 13.6% felt that CVD risk factors in their LTR patients were well controlled. Barriers to CVD care for LTRs included (1) lack of awareness of CVD risk after LT, (2) lack of confidence in an ability to provide proper CVD care to LTRs, (3) reluctance to provide CVD care without transplant provider review, and (4) complexity of communication with the multidisciplinary LTR care team about CVD care. Participant recommendations included improved education for LTRs and caregivers about CVD risk factors, electronic health record alerts for providers, clearly defined CVD care provider roles, increased use of the transplant pharmacist, and multidisciplinary provider meetings to discuss care plans for LTRs. Multiple barriers to CVD care after LT were identified, and targeted recommendations were proposed by participants. Transplant centers should integrate participants' recommendations when designing interventions to optimize CVD care for LTRs.

A number of medications may cause oral ulceration by either systemic or local mechanisms. Alendronic acid tablets, when in prolonged contact with the oral mucosa, are one such medication. When prescribing alendronic acid tablets, it is important to ensure that the patient is able to take them correctly and, if this is not the case, that alternative methods of bone protection are considered. When patients present with oral ulceration, it is important to consider whether a medicine could be causing a localized tissue reaction. This case series highlights three cases of alendronic acid-induced oral ulceration. CPD/Clinical Relevance: Practitioners should be aware of the potential oral unwanted effects of medications, including oral ulceration induced by prolonged mucosal contact with alendronic acid.

The development and implementation of a biopsy safety strategy is described in this article. Analysis of previous adverse incidents relating to biopsies acted as a catalyst to review our biopsy pathway at Liverpool University Dental Hospital. Input from all staff involved enabled us to develop a biopsy safety strategy which was divided into five stages: preoperative assessment of patient and procedure, team briefings, biopsy surgical safety checklist, surgical removal and handling of biopsy specimens, and post-biopsy follow-up. It is hoped that other clinical teams will take the opportunity to review their own biopsy processes, in the light of our experience.
