Published: October 2023

Background Postdromal symptoms, following headache resolution, are said to constitute a distinct phase of the migraine attack. We question the evidence for this, with regard both to the nature of such symptoms and to how often they are reported to occur. Methods We searched the Pubmed and Embase databases for relevant articles from their inception until 25 May 2023. We included observational studies recording the proportions of participants with migraine reporting one or more postdromal symptoms or specific individual symptoms. Two reviewers independently screened studies for relevance (agreeing on those to be included), extracted data and assessed risk of bias. Data were analyzed using random-effects meta-analysis to establish the proportions of those with migraine reporting one or more postdromal symptoms, whether among the general population or patients in clinic-based samples. Results Large majorities of participants in either case reported postdromal symptoms: 97% in the only population-based study, and a mean of 86% (95% CI: 71–94%) in four clinic-based studies. The most commonly reported specific symptoms were fatigue (52%; 95% CI: 44–60%), concentration difficulties (35%; 95% CI: 14–65%) and mood changes (29%; 95% CI: 9–64%), none of these being clearly described. These estimates could not be considered reliable: they were subject to substantial study heterogeneity, none of the studies applied International Classification of Headache Disorders definitions of postdromal symptoms, and all had high risk of bias. Conclusion Postdromal symptoms in migraine appear to be very commonly reported, but the data are unreliable with regard both to their nature and to how often they occur. Further studies are needed to conclude that they constitute a distinct phase of migraine.

Published: October 2023

Background: Long-term studies on arthroscopic repair of large subscapularis (SSC) tears over the first facet with or without supraspinatus (SSP) tear are limited. Purpose: To assess the structural and clinical outcomes of arthroscopic repair of large SSC tears using magnetic resonance imaging (MRI) and identify the factors related to SSC retear and poor outcomes. Study Design: Case series; Level of evidence, 4. Methods: This study involved 109 patients (84.0 ± 36.2 months of follow-up) who underwent arthroscopic repair of large SSC tears (Yoo and Rhee classification type III [n = 81] or IV [n = 28]) between 2011 and 2019. All patients underwent MRI at 6.1 ± 0.4 months after surgery, and 79 of 109 patients (72.5%) were followed up over 7 years. Clinical outcomes (active range of motion, functional scores, and belly press strength) and final poor clinical outcomes (reoperation, osteoarthritic change, and poor clinical outcome) were recorded. SSP tear size, rotator cuff atrophy and fatty infiltration (Goutallier classification), SSC tendon integrity (intact, intermediate, definite tear), and SSP tendon integrity (Sugaya classification) were evaluated by MRI. Results: The overall SSC retear rate was 8.3% (9/109) (type III, 2/81 [2.5%]; type IV, 7/28 [25.0%]; P < .001). SSC Goutallier grade 4 showed a higher retear rate than grade 3 (7/33 [21.2%] vs 2/33 [6.1%]; P = .149). A large SSP tear (in millimeters) (odds ratio [OR], 1.5; P = .003), SSC Goutallier grade 4 (OR, 10.8; P = .047), and SSP Goutallier grade 3 or 4 (OR, 0.02; P = .013) were independent factors for SSC retear. Clinical outcomes, except for external rotation, were poorer in patients with SSC retear than in those without retear. Final poor clinical outcomes were observed in 27 of 79 patients (34.2%); female sex (OR, 7.7; P = .007), SSC retear (OR, 8.2; P = .025), and SSP retear (OR, 4.7; P = .031) were independent factors. Conclusion: Arthroscopic repair of large SSC tears has shown promising structural outcomes for type III tears but not type IV tears. SSC retear was affected by SSC atrophy, as well as SSP tear size and atrophy. Approximately one-third of the final poor clinical outcomes could be predicted, and SSC retear, SSP retear, and female sex were associated with long-term poor clinical outcomes, underscoring the importance of carefully selecting patients for arthroscopic repair of large SSC tears.
High Non-affordability of Diets and Malnutrition in Africa’s Drylands: Systems Analysis to Guide Action
Authors: Hobbs Nora , Hug Julia , de Pee Saskia 
Published: October 2023

Background: Africa’s drylands have unique food environments and persistently high rates of wasting and stunting. This article documents findings and experiences from Fill the Nutrient Gap (FNG) processes conducted in 7 Sub-Saharan African countries that include drylands. Objective: This study advocates for a comprehensive consideration of the specific food environments of drylands using a novel analytical framework and shares findings and best practices for improving food and nutrition security in these contexts. Methods: Three analyses are combined. Analysis 1 re-analyzes cost and non-affordability of nutrient-adequate diets indicators from FNGs by reclassifying areas as drylands and non-drylands. Analysis 2 uses malnutrition estimates in drylands and non-drylands and examines associations with non-affordability of nutrient-adequate diets. Analysis 3 synthesizes evidence from FNG processes to document how those indicators were used to engage stakeholders and inform nutrition policy and practice in drylands. Results: The nutrient-adequate diet of a 5-person household was 2.60 USD (41%) more expensive in drylands. A nutrient-adequate diet was not affordable to 71% of households in drylands, compared to 55% in non-drylands. Wasting and stunting prevalence and non-affordability of nutrient-adequate diets were simultaneously high in drylands. Conclusion: The article presents new evidence that contributes to elucidate specific characteristics of the food environment of Africa’s drylands and suggests a framework to improve on those factors systematically. The FNG is innovative in combining an analytical framework with multistakeholder review and dialogue, as well as modeling of possible strategies, to build consensus on possible transformation pathways to improve diets in drylands.

Published: October 2023

Background Lymphomatosis cerebri (LC) is a rare manifestation of primary central nervous system lymphoma (PCNSL) with only a few cases reported in the literature, appearing as diffuse infiltrating process rather than a solitary mass. It is a non-Hodgkin’s type of lymphoma and is usually of the B-cell type origin. Purpose We intend to report this unique case of LC which came across as a diagnostic challenge. Methods A 53-year-old gentleman presented with complaints of two episodes of seizures 24 h apart followed by postictal confusion for 10–15 min. He underwent multiple MRI scans and underwent a biopsy of the lesion which reported infection, but he did not benefit from the treatment. Result The imaging was reviewed, suspicion of LC was raised and a review of histopathology was requested which later confirmed primary CNS lymphoma. Conclusion LC is a rare but established manifestation of PCNSL which mimics multiple other conditions. Understanding of the imaging pattern is important in making the diagnosis and differentiating it from other mimic conditions.
Informal Social-Emotional Learning in Gaming Affinity Spaces: Evidence From a Reddit Discussion Thread on Elden Ring
Authors: Czauderna André , von Gillern Sam , Robinson Bradley 
Published: October 2023

Background Over the past few years, there has been extensive discussion and research on social-emotional learning (SEL) in formal educational settings. However, there is limited research on SEL in informal learning contexts, including online sites such as gaming affinity spaces. Aim This qualitative study aimed to investigate the social-emotional competencies demonstrated by players in a Reddit discussion board focused on Elden Ring, a video game known for its challenging difficulty. Methods The study utilized theoretical qualitative thematic analysis on a focal thread at r/Eldenring. The thread had been upvoted over 18,000 times, included 2,363 comments encompassing 116,911 words, and had 997,765 readers when we extracted it for data analysis. Inductive codes were identified and grouped under preconceived themes based on the conceptual framework of the Collaborative for Academic, Social, and Emotional Learning (CASEL), which comprises five components: self-awareness, self-management, social awareness, relationship skills, and responsible decision-making. Findings The analysis revealed promising social-emotional competencies demonstrated by players across all five components of the CASEL framework. Players exhibited self-awareness by reflecting on their emotions and self-management by regulating their frustration and persevering through challenges. Social awareness was displayed by showing empathy and encouragement towards others, relationship skills by offering support and advice to fellow players, and responsible decision-making by analyzing situations, solving problems, and reflecting on gameplay experiences. Conclusion This study highlights the potential for informal SEL in gaming affinity spaces, as evidenced by players exhibiting social-emotional competencies during a Reddit discussion thread on Elden Ring. Future research should examine, among other aspects, the learning processes that facilitate the acquisition of social-emotional competencies in gaming affinity spaces and other informal learning environments, both online and offline. Additionally, special attention should be paid to the unique features of online platforms (like Reddit’s upvoting/downvoting) and their influence on users’ interactions and SEL.
Caregiver and Employee Experience Among Big Hospices—Ranking of the Largest US Hospices by Three Quality Indicators
Authors: Hotchkiss Jason , Ridderman Emily , Hotchkiss Brendan 
Published: October 2023

Background Several studies chronicle profit-making negatively impacting US hospice care quality. However, no study has reported on caregiver satisfaction expressed online by hospice. Objectives Assess the relationship between online caregiver sentiment, market share, profit status, and Consumer Assessment of Healthcare Providers and Systems (CAHPS®) scores among the 50 largest US hospices. Methods Retrospective mixed methods of sentiment and multivariate regression analysis. Data sources were online caregiver reviews, provider CAHPS hospice survey data. Results Being a larger, for-profit predicted diminished caregiver and employee satisfaction. Caregiver Sentiment and CAHPS Composite were so highly associated ( r = .862, P < .001), that they are converging on overall caregiver satisfaction. With large effect, CAHPS Star Rating was significantly higher than Review Star Rating. For-profits had significantly higher overall Emotional Intensity than non-profit hospices, again with large effect. Caregiver Sentiment, Review Star Rating, and Glassdoor Composite each predicted CAHPS Composite. Lack of staffing was more frequent among for-profits (13%) than non-profits (6%). Out-of-scope expectations prevalence was 9%. Conclusion Caregiver and employees had better experiences with non-profits than for-profits. Anger and frustration was expressed toward large, for-profit providers more focused on admissions, profiteering, and paying dividends than actual care. The CAHPS appears to draw more satisfied caregivers. Whereas, online reviewing provides open-ended, real-time voicing of care quality concerns. Even with distinct methods, CAHPS survey and review sentiment analysis converge on caregiver satisfaction, yet CAHPS paints a much rosier picture of hospice quality than online reviews. Future research should explore sentiments by topic and hospice to increase customer advocacy.

Published: October 2023

Introduction Telehealth has become increasingly routine within healthcare and has potential to reduce barriers to care, including for Indigenous populations. However, it is crucial for practitioners to first ensure that their telehealth practice is culturally safe. This review aims to describe the attributes of culturally safe telehealth consultations for Indigenous people as well as strategies that could promote cultural safety. Methods A scoping review was conducted on key features of cultural safety in telehealth for Indigenous people using the Johanna Briggs Institute (JBI) guidelines and PRISMA-ScR checklist. Five electronic databases were searched, and additional literature was identified through handsearching. Results A total of 649 articles were screened resulting in 17 articles included in the review. The central themes related to the provision of culturally safe telehealth refer to attributes of the practitioner: cultural and community knowledge, communication skills and the building and maintenance of patient–provider relationships. These practitioner attributes are modified and shaped by external environmental factors: technology, the availability of support staff and the telehealth setting. Discussion This review identified practitioner-led features which enhance cultural safety but also recognised the structural factors that can contribute, both positively and negatively, to the cultural safety of a telehealth interaction. For some individuals, telehealth is not a comfortable or acceptable form of care. However, if strategies are undertaken to make telehealth more culturally safe, it has the potential to increase opportunities for access to care and thus contribute towards reducing health inequalities faced by Indigenous peoples.

Published: October 2023

Three different institutions combined their expertise in a joint R&D project to demonstrate the suitability of terahertz time-domain spectroscopy for thickness measurements of acrylate-based coatings on polyester fabric. First, we spectroscopically analyzed the materials involved using a high-precision terahertz spectrometer and determined optical properties such as the refractive index and loss coefficient. Raster scans were then performed across the sample, and terahertz images were created to identify material boundaries and thickness inhomogeneities. Finally, we applied a fast scanning terahertz time-domain spectrometer based on electronically controlled optical sampling and a customized reflection head for online thickness measurements in a coating line. The textile moved at a speed of 0.5 m/min, while the measurement system records terahertz pulses at a rate of 1600 traces/s. Coating thicknesses of between 63 µm and 99 µm were calculated in a post-processing step. To classify these non-contact and non-destructive measurements, these thicknesses were compared with the results of standard methods. Online and offline (62-83 µm) terahertz and SEM (66-75 µm) measurements delivered the best agreement for average coating thickness. In contrast, mechanical testing methods gave either too low or too high values for layer thickness, which were not comparable. Terahertz time-domain spectroscopy and imaging technology enable the first non-destructive quality control of acrylate-based textile coatings immediately following coating in the production line. Measurable variables are coating thicknesses and the detection of defects such as air inclusions.

Published: October 2023

Background Healthcare providers carry the occupational risk of being exposed to pathogens. Personal Protection Equipment (PPE) requires proficiency whenever used. Yet, evidence shows significant errors and variation in competency when applying PPE. Objective In this study, we developed a three-phase intervention to promote PPE proficiency. Methods Education and assessment of participants’ PPE knowledge and skills occurred at a large academic university in Western Canada. Participants first completed an online module; second, they experienced one-on-one coaching and deliberate practice with infection control professionals; and third, participants managed a COVID-19 clinical simulation scenario. The measured outcomes include a 15-item pre- and post-knowledge test and a pre- and post-skills assessment of donning and doffing behaviors. These behaviors were observed from video recordings and were assessed using two standardized checklists. Results Knowledge and donning/doffing post-test scores (11.73, 0.95, and 0.96, respectively) were significantly higher after completing all three phases of the educational intervention, p < .001. Conclusions An online module alone is insufficient for PPE knowledge and skill development. Rather, a module followed by practice and simulation allows learners to gain proficiency.

Published: October 2023

Objective We aimed to evaluate the outcomes, survivorship, and complications following multi-surface cartilage procedures at minimum 2-year follow-up. Design Patients with either (1) single-surface osteochondral allograft transplantation (OCAT) with third-generation matrix-induced autologous cultured chondrocyte implantation (MACI) or particulated juvenile cartilage implantation (DeNovo), or (2) multiple-surface OCAT ± associated MACI/DeNovo procedures for grade IV chondral or osteochondral defects about the knee with minimum 2-year follow-up were analyzed. Patient-reported outcome measures (PROMs), including International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales, were obtained preoperatively and at minimum 2 years postoperatively. The percentage of patients who met the minimal clinically important difference (MCID) for each PROM was reported. Failure was defined as revision OCAT, conversion to patellofemoral/total/unicompartmental joint arthroplasty, or Arthrosurface HemiCAP placement. Results Of 257 patients identified, 35 were included. There was a significant increase in IKDC, KOOS-pain, KOOS-symptom, KOOS-sport, and KOOS-quality of life scores from preoperative to postoperative evaluation ( P < 0.03 for all). More than 50% of patients met the MCID for each PROM. There were 2 failures, 1 of the patella and 1 of the medial femoral condyle, at 39.7 and 38.6 months postoperatively, respectively. Discussion Multi-surface cartilage procedures are a safe, efficacious treatment option for multifocal cartilage defects about the knee at short-term follow-up.
‘I felt part of the solution’. A qualitative study about the interface between lived experience advocates, professionals and organisations in the field of persistent pain
Authors: Hartley Cameron , Penlington Chris 
Published: October 2023

Objectives To elicit perspectives of people with persistent pain about their experiences working with pain management professionals and services as patient advocates and to consider implications for current models of involving patients in service development and research. Design reflexive thematic analysis from a critical realist perspective. Methods Online interviews were conducted individually with 10 participants who had acted as patient advocates in the field of persistent pain. Participants were recruited through purposive and snowball sampling. Data were analysed and organised into themes and are presented descriptively. Results The relationship between patient advocates and the organisations they help is conceptualised as ‘an unequal partnership’. Participants described positive and affirming experiences with individual health professionals and research teams (Respect). This often occurred within a context of inflexible organisational policies that presented barriers to participation including a lack of financial compensation and expectation to work to inflexible deadlines. As a result, patient advocates could experience a lack of value attributed to their experiences and voices (unmet needs from institutions). Conclusion People with personal experience of engaging with services for persistent pain are in a strong position to contribute to service improvement. Although this contribution is recognised as valuable, it appears to be devalued by organisational barriers. Organisational policies around payment may lead to a lack of representation of those experiencing higher levels of disadvantage. As a result, services and policy makers may be missing out on insights that could be important for service development.

Objective Compas-Y is a compassionate mind training app that was co-designed to be fully adapted to mobile technology and to people with newly diagnosed cancer. This study aimed to evaluate the use, appreciation and impact of the app. Methods Seventy-one people with cancer who created an app account were included (38% breast cancer, 72% diagnosed <4 months ago, 76% received chemotherapy). Participants had very high baseline scores of self-compassion. In a convergent mixed methods design, back-end log-data ( n = 71), pre-post surveys ( n = 34) and semi-structured interviews ( n = 23) collected for >8 weeks and were concurrently analysed using joint displays. Results About half of the participants (45%) used 4 of the 6 modules. Compas-Y was highly appreciated, with all content considered relevant and a source of support. Experienced benefits related to improved mental health. Particularly, we found significant changes in anxiety, but not in depression or well-being. In the interviews, people reported experiencing more rest and more positive emotions due to using the app. Process benefits included significant reductions in self-criticism (inadequate self and self-blame), but not self-compassion. In the interviews, people reported improved self-compassion and less self-criticism, more self-awareness, recognition and support, and improved emotion regulation and coping. The surveys did not capture the full range of outcomes that participants reported in the interviews. Conclusions Compas-Y is a highly appreciated mobile intervention that supported users in aspects of their mental health. Findings are discussed in terms of reach and adherence, app functionalities, co-design and tailoring of cancer-related and compassion-based eHealth.
