Background We evaluated associations between antibiotic prescription and healthcare resource use and costs (Part A), and between antibiotic switching and healthcare resource use, costs, and uncomplicated urinary tract infection recurrence (Part B) in female patients with uncomplicated urinary tract infection in the United States. Methods This retrospective cohort study of linked Optum and Premier Healthcare Database data included female patients ≥12 years old with an uncomplicated urinary tract infection diagnosis (index date), who were prescribed antibiotics during an outpatient/emergency department visit between January 1, 2013 and December 31, 2018. In Part A, patients were stratified by antibiotic prescription appropriateness: appropriate and optimal (compliant with Infectious Diseases Society of America 2011 guidelines for drug class/treatment duration) versus inappropriate/suboptimal (inappropriate drug class/treatment duration per Infectious Diseases Society of America 2011 guidelines, and/or treatment failure). In Part B, patients were stratified by treatment pattern (antibiotic switch vs no antibiotic switch). Healthcare resource use and costs during index episode (within 28 days of index date) and 12-month follow-up were compared. Results Of 5870 patients (mean age 44.5 years), 2762 (47.1%) had inappropriate/suboptimal prescriptions and 567 (9.7%) switched antibiotic. Inappropriate/suboptimal prescriptions were associated with higher healthcare resource use (mean number of ambulatory care and pharmacy claims [both p < 0.001]), and higher total mean cost (inpatient, outpatient/emergency department, ambulatory visits, and pharmacy costs) per patient ($2616) than appropriate and optimal prescriptions ($649; p < 0.001) (Part A). Antibiotic switching was associated with more pharmacy claims and higher total mean costs (p ≤ 0.01), and a higher incidence of recurrent uncomplicated urinary tract infection (18.9%) than no antibiotic switching (14.2%; p < 0.001) (Part B). Conclusions Inappropriate/suboptimal prescriptions and antibiotic switching were associated with high costs, ambulatory care, and pharmacy claims, suggesting a need for improved uncomplicated urinary tract infection prescribing practices in the United States.

Detrimental changes in the composition and function of rotator cuff (RC) muscles are hallmarks of RC disease progression. Previous studies have demonstrated both atrophic and degenerative muscle loss in advanced RC disease. However, the relationship between gene expression and RC muscle pathology remains poorly defined, in large part due to a lack of studies correlating gene expression to tissue composition. Therefore, the purpose of this study was to determine how tissue composition relates to gene expression in muscle biopsies from patients undergoing reverse shoulder arthroplasty (RSA). Gene expression related to myogenesis, atrophy and cell death, adipogenesis and metabolism, inflammation, and fibrosis was measured in 40 RC muscle biopsies, including 31 biopsies from reverse shoulder arthroplasty (RSA) cases that had available histology data and 9 control biopsies from patients with intact RC tendons. After normalization to reference genes, linear regression was used to identify relationships between gene expression and tissue composition. Hierarchical clustering and principal component analysis (PCA) identified unique clusters, and fold-change analysis was used to determine significant differences in expression between clusters. We found that gene expression profiles were largely dependent on muscle presence, with muscle fraction being the only histological parameter that was significantly correlated to gene expression by linear regression. Similarly, samples with histologically-confirmed muscle distinctly segregated from samples without muscle. However, two sub-groups within the muscle-containing RSA biopsies suggest distinct phases of disease, with one group expressing markers of both atrophy and regeneration, and another group not significantly different from either control biopsies or biopsies lacking muscle. In conclusion, this study provides context for the interpretation of gene expression in heterogeneous and degenerating muscle, and provides further evidence for distinct stages of RC disease in humans.

Objectives: Huntington disease (HD) is associated with a variety of cognitive deficits, with prominent difficulties in working memory (WM). WM deficits are notably compromised in early-onset and prodromal HD patients. This study aimed to determine the feasibility of a computerized WM training program (Cogmed QM), novel to the HD population., Methods: Nine patients, aged 26-62, with early stage HD underwent a 25-session (5 days/week for 5 weeks) WM training program (Cogmed QM). Training exercises involved the manipulation and storage of verbal and visuospatial information, with difficulty adapted as a function of individual performance. Neuropsychological testing was conducted before and after training, and performance on criterion WM measures (Digit Span and Spatial Span), near-transfer WM measures (Symbol Span and Auditory WM), and control measures were evaluated. Post-training interviews about patient experience were thematically analyzed using NVivo software., Results: Seven of nine patients demonstrated adherence to the training and completed all sessions within the recommended timeframe of 5 weeks. All adherent patients showed improvement on the Cogmed tasks as defined by the Improvement Index (M = 22.17, SD = 8.84, range = 13-36). All adherent patients reported that they found training helpful (n = 7), and almost all felt that their memory improved (n = 6). Participants also expressed that the training was difficult, sometimes frustrating, and time consuming., Conclusions: This pilot study provides support for feasibility of computerized WM training in early-stage patients with HD. Results suggest that HD patients perceive benefits of intensive WM training, though a full-scale and controlled intervention project is needed to understand the size of the effect and reliability of changes over time., Trial Registration: ClinicalTrials.gov, Registry number NCT02926820.

International and national health policy seeks to increase service user and carer involvement in mental health care planning, but suitable user-centred tools to assess the success of these initiatives are not yet available. The current study describes the development of a new reliable and valid, interval-scaled service-user and carer reported outcome measure for quantifying user/carer involvement in mental health care planning. Psychometric development reduced a 70-item item bank to a short form questionnaire using a combination of Classical Test, Mokken and Rasch Analyses. Test-retest reliability was calculated using t-tests of interval level scores between baseline and 2-4 week follow-up. Items were worded to be relevant to both service users and carers. Nine items were removed following cognitive debriefing with a service user and carer advisory group. An iterative process of item removal reduced the remaining 61 items to a final 14-item scale. The final scale has acceptable scalability (Ho = .69), reliability (alpha = .92), fit to the Rasch model (χ2(70) = 97.25, p = .02), and no differential item functioning or locally dependent items. Scores remained stable over the 4 week follow-up period, indicating good test-retest reliability. The 'Evaluating the Quality of User and Carer Involvement in Care Planning (EQUIP)' scale displays excellent psychometric properties and is capable of unidimensional linear measurement. The scale is short, user and carer-centred and will be of direct benefit to clinicians, services, auditors and researchers wishing to quantify levels of user and carer involvement in care planning.
