The present study examines the extent to which a two-factor model of affect explains how caregiving appraisals experienced by caregivers influence their own well-being. We used data from three waves of Nation Study of Caregiving (NSOC) to conduct latent growth curve models with the time-varying predictors to investigate the effect of between-person (BP) and within-person (WP) caregiving appraisals on positive and negative affect. Furthermore, we simultaneously modeled WP differences in activity participation and affective experience with multilevel modeling. Then, we tested the moderating effect of activity participation in the association between WP caregiving appraisals and emotional valence. We found that BP and WP caregiving negative appraisal also contribute to caregiver positive affect similar to that of negative affect. Time-varying effects of negative appraisals and emotional valence are consistent with the two-factor model. Future longitudinal investigations could target WP and BP activity participation to alleviate caregiving cognitive appraisal among caregivers.

Background: The changes in health, social and demographic needs impose new approaches to cures and care without giving up patients' safety. Although several studies analysed the patient safety approach and strategies, the literature considering the home care setting seems still scarce. The analysis of the phenomenon of medication errors in the primary care setting highlights the necessity of exploring the specific variables to understand how to prevent or reduce the occurrence of a medication error in the home context. This review investigates the main preventive strategies implemented at the patient's home to prevent and/or limit the possibility of a medication error.

Design: The scoping review was conducted under the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) statement and based on the guidelines of the Joanna Briggs Institute.

Methods: No time or language limit was set to obtain the most comprehensive results possible. The following databases were queried: PubMed, Cochrane, CINAHL, ERIC and PsycINFO via EBSCO. All literature published up to 31 December 2022 was considered for data collection.

Results: The main preventive strategies implemented in the patient's home to prevent a medication error are: Multidisciplinary teams, therapeutic reconciliation and computerised systems that improve information sharing. As evidenced by all of the included studies, no educational intervention or preventive strategy individually reduces the risk of making a medication error.

Conclusions: It would be desirable for healthcare professionals to be constantly updated about their knowledge and understand the importance of introducing the aforementioned preventive strategies to guarantee safe care that protects the person from medication errors even at the patient's home.

Purpose: Conventional metrics used for assessing digital mammography (DM) and digital breast tomosynthesis (DBT) image quality, including noise, spatial resolution, and detective quantum efficiency, do not necessarily predict how well the system will perform in a clinical task. A number of existing phantom-based methods have their own limitations, such as unrealistic uniform backgrounds, subjective scoring using humans, and regular signal patterns unrepresentative of common clinical findings. We attempted to address this problem with a realistic breast phantom with random hydroxyapatite microcalcifications and semi-automated deep learning-based image scoring. Our goal was to develop a methodology for objective task-based assessment of image quality for tomosynthesis and DM systems, which includes an anthropomorphic phantom, a detection task (microcalcification clusters), and automated performance evaluation using a convolutional neural network.

Approach: Experimental 2D and pseudo-3D mammograms of an anthropomorphic inkjet-printed breast phantom with inserted microcalcification clusters were collected on clinical mammography systems to train a signal-present/signal-absent image classifier based on Resnet-18 architecture. In a separate validation study using simulations, this Resnet-18 classifier was shown to approach the performance of an ideal observer. Microcalcification detection performance was evaluated as a function of four dose levels using receiver operating characteristic (ROC) analysis [i.e., area under the ROC curve (AUC)]. To demonstrate the use of this evaluation approach for assessing different technologies, the method was applied to two different mammography systems, as well as to mammograms with re-binned pixels emulating a lower-resolution X-ray detector.

Results: Microcalcification detectability, as assessed by the deep learning classifier, was observed to vary with the exposure incident on the breast phantom for both DM and tomosynthesis. At full dose, experimental AUC was 0.96 (for DM) and 0.95 (for DBT), whereas at half dose, it dropped to 0.85 and 0.71, respectively. AUC performance on DM was significantly decreased with an effective larger pixel size obtained with re-binning. The task-based assessment approach also showed the superiority of a newer mammography system compared with an older system.

Conclusions: An objective task-based methodology for assessing the image quality of mammography and tomosynthesis systems is proposed. Possible uses for this tool could be quality control, acceptance, and constancy testing, assessing the safety and effectiveness of new technology for regulatory submissions, and system optimization. The results from this study showed that the proposed evaluation method using a deep learning model observer can track differences in microcalcification signal detectability with varied exposure conditions.

Pharmacogenetics promises to optimize treatment-related outcomes by informing optimal drug selection and dosing based on an individual's genotype in conjunction with other important clinical factors. Despite significant evidence of genetic associations with drug response, pharmacogenetic testing has not been widely implemented into clinical practice. Among the barriers to broad implementation are limited guidance for how to successfully integrate testing into clinical workflows and limited data on outcomes with pharmacogenetic implementation in clinical practice. The Pharmacogenomics Global Research Network Implementation Working Group seeks to engage institutions globally that have implemented pharmacogenetic testing into clinical practice or are in the process or planning stages of implementing testing to collectively disseminate data on implementation strategies, metrics, and health-related outcomes with the use of genotype-guided drug therapy to ultimately help advance pharmacogenetic implementation. This paper describes the goals, structure, and initial projects of the group in addition to implementation priorities across sites and future collaborative opportunities.

Transitioning to adulthood is a complex and challenging process for youth with complex communication needs (CCN) and/or who use augmentative and alternative communication (AAC). This scoping review examined and consolidated available evidence documenting transition barriers and facilitators. Eight databases were searched systematically using complex communications needs/augmentative and alternative communication, transition programs, and adulthood as key terms. Participants aged 14-35 years and interventions focused on transition to occupations, including education, employment, leisure pursuits, or socializing/relationships. The search yielded 3459 records, which were screened by three independent raters. Twenty-three articles met the inclusion criteria. Studies focused primarily on employment (n =18), postsecondary education (n = 10), and socializing/relationships (n = 13). Programs experience and outcomes varied. Enabling factors included organizations, transition-focused programs, and social networks. Barriers included low expectations, lack of programs/supports, and limited literacy skills. Future studies must include richer descriptions of programs/services and participants, while more work is required to explore long-term outcomes.

Objective: Oral corticosteroids (OCS) are frequently prescribed by otolaryngologists. However, there are limited quantitative data on OCS-related adverse events (AEs) in otolaryngology. We sought to quantify OCS-related AEs in otolaryngology.

Methods: All outpatient otolaryngology encounters in our healthcare system (2018-2023) at which an OCS was prescribed were identified via the electronic medical record. The diagnoses indicating OCS were categorized as sinonasal, otologic, pharyngo-laryngeal, and other. The medical record was subsequently examined to assess for OCS AEs during the 21-day period following the prescription. OCS AEs were grouped into (1) gastrointestinal, (2) metabolic, (3) bone/muscle, (4) ophthalmologic, and/or (5) psychiatric complications. The frequency and types of OCS related AEs were determined.

Results: A total of 20 746 otolaryngology encounters with OCS prescribed were examined. Seventy OCS courses had 1 or more AEs, implying a number needed to harm of 296.4 (240.2-386.8). There were 83 total OCS-related AEs, yielding an AE incidence rate of 4.0:1000 (95% CI, 3.0-5.0:1000) OCS prescriptions. The mean age of subjects with AEs (61.5 years) was significantly higher than those without (50.3 years; P < .001). Forty-seven (56.6%) of the complications were metabolic, with hyperglycemia and hypokalemia the most common, followed by gastrointestinal (26.5%), ophthalmologic (3.6%), psychiatric (2.4%), and musculoskeletal (2.4%).

Conclusion: AEs related to OCS prescribed by otolaryngologists occur at a rate of once per 296 courses of treatment and older populations may be at increased risk for AEs. Otolaryngologists should balance AE rates against anticipated benefits of steroid therapy.

Objective: Nasal airway surgery is often applied when treatment fails to relieve nasal obstruction. However, surgery that improves airflow does not always alleviate the symptoms of nasal obstruction. The perception of nasal breathing is likely more related to changes in mucosal temperature than the mechanical sensation of flow or pressure. This study aims to measure intranasal mucosal temperature pre-and post-surgery using endonasal thermal imaging, exploring its correlation with subjective nasal breathing and objective airflow measurements.

Methods: A prospective study of adult patients with nasal obstruction managed with nasal airway surgery was performed. Intranasal mucosal temperatures were determined using the thermal endonasal image of the nasal passage produced by the infrared radiometric thermal camera (FILR VS290). A comparison was made between the mean values of mid-expiration (ExT) and mid-inspiration (InT) temperature data (internal nasal valve, nasal cavity, inferior turbinate, and overall airway [mean value]) and visual analog scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE) scale and nasal airway resistance (NAR) before and after surgery.

Results: Seven patients (35.14 ± 16.45 years, 57.14% female) were included. All NOSE, VAS, and NAR improved after surgery (59.29 ± 10.89 vs 17.14 ± 14.64; P < .001, 64.50 ± 26.79 vs 18.57 ± 19.99; P < .001, 0.82 ± 0.48 vs 0.34 ± 0.11 Pa/cm³/s; P = .002, respectively). ExT, InT, and the difference between ExT and InT of three areas and overall airway were similar between pre-and post-surgery. No statistically significant correlations were found between intranasal mucosal temperature, VAS, NOSE, and NAR at pre-and post-surgery except for the difference between ExT and InT of overall airway and NOSE pre-operative (Pearson r = 0.57; 95% CI 0.06-1.09; P = .03).

Conclusion: Endonasal thermal imaging can assess the intranasal mucosal temperature of a patient. However, more precise imaging of the nasal passages and data acquisition are required to establish mucosal temperature as an objective measure of nasal obstruction before and after nasal airway surgery in a clinical setting.

Introduction: Perforations of the tympanic membrane result mainly from otitis media or trauma, and we need grafting when a perforation is chronically persistent to prevent recurring infections and to enhance hearing. In the present study, we assessed the success rate, feasibility, and efficacy of endoscopic transcanal tympanoplasty using tragal cartilage grafts via the clip technique.

Methods: This prospective study was performed between September 2017 and December 2021 and was conducted in ENT departments in tertiary hospitals. Forty patients underwent endoscopic clip technique tragal cartilage type 1 tympanoplasty. Patients with dry (for 3 months at least) small (less than 3 mm), medium (3-5 mm), or large (more than 5 mm) central perforations but not marginal perforations.

Results: TM perforation healing following the procedure for 6 months was achieved in 100% of the patients with small perforations, 18 of 19 (94.73%) with medium perforations and 11 of 12 (91.6%) with large perforations. At 6 months post-surgery, hearing improvement, as confirmed by audiometric results, was approximately 12.41 ± 1.01 dB. There was a highly significant improvement in the A-B gap (air-bone gap).

Conclusion: Endoscopic chondro-perichondrial tragal graft with the clip technique for the repair of small-, medium-, and large-sized nonmarginal TM perforations is a minimally invasive, safe and effective technique compared with the conventional myringoplasty technique. It provided good results (closure of both the perforation and the air-bone gap), minimized morbidity, reduced the operative time, increased patient compliance, and reduced the duration of hospital admission.
