ABSTRACT
OBJECTIVES: This study aimed to investigate (1) definitions of self-isolation used during the COVID-19 pandemic; (2) measures used to quantify adherence and their reliability, validity, and acceptability; (3) rates of self-isolation adherence; and (4) factors associated with adherence. STUDY DESIGN: This was a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Synthesis Without Meta-analysis (PRISMA) guidelines (PROSPERO record CRD42022377820). METHODS: MEDLINE, PsycINFO, Embase, Web of Science, PsyArXiv, medRxiv, and grey literature sources were searched (1 January 2020 to 13 December 2022) using terms related to COVID-19, isolation, and adherence. Studies were included if they contained original, quantitative data of self-isolation adherence during the COVID-19 pandemic. We extracted definitions of self-isolation, measures used to quantify adherence, adherence rates, and factors associated with adherence. RESULTS: We included 45 studies. Self-isolation was inconsistently defined. Four studies did not use self-report measures. Of 41 studies using self-report, one reported reliability; another gave indirect evidence for the lack of validity of the measure. Rates of adherence to self-isolation for studies with only some concerns of bias were 51%-86% for COVID-19 cases, 78%-94% for contacts, and 16% for people with COVID-19-like symptoms. There was little evidence that self-isolation adherence was associated with sociodemographic or psychological factors. CONCLUSIONS: There was no consensus in defining, operationalising, or measuring self-isolation, resulting in significant risk of bias in included studies. Future definitions of self-isolation should state behaviours to be enacted and duration. People recommended to self-isolate should be given support. Public health campaigns should aim to increase perceived effectiveness of self-isolation and promote accurate information about susceptibility to infection.
ABSTRACT
BACKGROUND: References to transformative and therapeutic benefits of digital storytelling are often made, yet this remains an under-explored area, which we foreground in this study. METHODS: A phenomenological research design was adopted to explore through interview how a purposive sample of Patient Voices storytellers experienced participation in more than one digital storytelling workshop. Analysis was through thematic coding, linguistic analysis and use of van Manen's lifeworld existentials framework. RESULTS: We find that for this particular group, the therapeutic and transformative experiences that re-centre and re-frame personal meaning do so through inter-personal connections and can be understood as a process of social learning. The lifeworld existentials analysis demonstrates that a pluralist and relational conception of wellbeing holds and there is a close relationship between this and Yalom's 11 therapeutic factors. CONCLUSIONS: Drawing on group analytic literature, we suggest the concept of a social learning methodology as useful in grounding further research that seeks to understand the beneficial impacts of digital storytelling methodologies in healthcare and in contributing evidence in this field with fidelity to the lived experience as central.
ABSTRACT
BACKGROUND: Candida auris is an emerging fungal pathogen increasingly recognized as a cause of healthcare-associated infections including outbreaks. METHODS: We performed a mixed-methods study to characterize the emergence of C. auris in the state of Maryland from 2019 to 2022, with a focus on socioeconomic vulnerability and infection prevention opportunities. We describe all case-patients of C. auris among Maryland residents from June 2019 to December 2021 detected by Maryland Department of Health. We compared neighborhood socioeconomic characteristics of skilled nursing facilities (SNFs) with and without C. auris transmission outbreaks using both the social vulnerability index (SVI) and the area deprivation index (ADI). The SVI and the ADI were obtained at the state level, with an SVI ≥ 75th percentile or an ADI ≥ 80th percentile considered severely disadvantaged. We summarized infection control assessments at SNFs with outbreaks using a qualitative analysis. RESULTS: A total of 140 individuals tested positive for C. auris in the study period in Maryland; 46 (33%) had a positive clinical culture. Sixty (43%) were associated with a SNF, 37 (26%) were ventilated, and 87 (62%) had a documented wound. Separate facility-level neighborhood analysis showed SNFs with likely C. auris transmission were disproportionately located in neighborhoods in the top quartile of deprivation by the SVI, characterized by low socioeconomic status and high proportion of racial/ethnic minorities. Multiple infection control deficiencies were noted at these SNFs. CONCLUSION: Neighborhood socioeconomic vulnerability may contribute to the emergence and transmission of C. auris in a community.
ABSTRACT
OBJECTIVE: Currently, human immunodeficiency virus (HIV) and multi-drug resistant tuberculosis (MDR-TB) without extensive drug resistance (XDR) are significant challenges in terms of the global burden of disease. This study aimed to evaluate the trends of the global burden of MDR-TB without XDR and HIV/AIDS-MDR-TB without XDR, focusing on differences in socioeconomic status and sex for 204 countries and territories across periods from 1990 to 2019. MATERIALS AND METHODS: Data from the Global Burden of Disease (GBD) 2019 study were obtained to construct a separate index measuring the burden of MDR-TB without XDR and HIV/AIDS-MDR-TB without XDR. Incidence, prevalence, mortality, and disability-adjusted life years (DALYs) were calculated for each case and group. A population-attributable fraction approach was used to assess mortality and incidence of HIV/AIDS and MDR-TB coinfection. 95% uncertainty intervals (UIs) were presented for all measures. RESULTS: Our global estimates suggest that there were approximately 450,000 (95% UI 247,000-785,000) incident cases of MDR-TB without XDR and 109,000 (43,000-210,000) deaths caused by MDR-TB without XDR among individuals who were HIV-negative in 2019. For HIV-positive individuals, the corresponding figures were approximately 47,000 (33,000-67,000) incident cases of MDR-TB and 19,000 (8,000-36,000) deaths due to MDR-TB in the same year. In 2019, higher numbers of incident cases and deaths were observed in males compared to females among individuals who were HIV-negative. Conversely, for HIV-positive individuals, females had higher numbers of incident cases and deaths compared to males. Specifically, the estimated numbers for incident cases were 23,000 (15,000-33,000) for females and 24,000 (17,000-35,000) for males, while the estimated numbers for deaths were 9,600 (4,000-17,900) for females and 9,800 (4,100-18,500) for males. Male-to-female ratios have remained above 1.0 from 1990 to 2019 in both incident cases and number of deaths for HIV-negative individuals. However, for HIV and MDR-TB coinfection, both ratios were below 1.0 in most of the time series. CONCLUSIONS: Males had more cases and deaths due to MDR-TB without XDR than females in HIV-negative patients, while females faced a higher incidence and mortality in HIV/AIDS-MDR-TB without XDR. Interventions are needed to deal with such factors, which increase the burden of coinfection among females across the world.

Macrophages play a key role in ozone-induced lung injury by regulating both the initiation and resolution of inflammation. These distinct activities are mediated by pro-inflammatory and anti-inflammatory/proresolution macrophages which sequentially accumulate in injured tissues. Macrophage activation is dependent, in part, on intracellular metabolism. Herein, we used RNA-sequencing (seq) to identify signaling pathways regulating macrophage immunometabolic activity following exposure of mice to ozone (0.8 ppm, 3 hr) or air control. Analysis of lung macrophages using an Agilent Seahorse showed that inhalation of ozone increased macrophage glycolytic activity and oxidative phosphorylation at 24 and 72 hr post exposure. An increase in the percentage of macrophages in S phase of the cell cycle was observed 24 hr post ozone. RNA-seq revealed significant enrichment of pathways involved in innate immune signaling and cytokine production among differentially expressed genes at both 24 and 72 hr after ozone, while pathways involved in cell cycle regulation were upregulated at 24 hr and intracellular metabolism at 72 hr. An interaction network analysis identified tumor suppressor 53 (TP53), E2F family of transcription factors (E2Fs), Cyclin Dependent Kinase Inhibitor 1A (CDKN1a/p21), and Cyclin D1 (CCND1) as upstream regulators of cell cycle pathways at 24 hr and TP53, nuclear receptor subfamily 4 group a member 1 (NR4A1/Nur77), and estrogen receptor alpha (ESR1/ERα) as central upstream regulators of mitochondrial respiration pathways at 72 hr. To assess whether ERα regulates metabolic activity, we used ERα-/-- mice. In both air and ozone exposed mice, loss of ERα resulted in increases in glycolytic capacity and glycolytic reserve in lung macrophages with no effect on mitochondrial oxidative phosphorylation. Taken together, these results highlight the complex interaction between cell cycle, intracellular metabolism, and macrophage activation which may be important in the initiation and resolution of inflammation following ozone exposure.
ABSTRACT
Introduction: The California purple sea urchin, Strongylocentrotus purpuratus, relies solely on an innate immune system to combat the many pathogens in the marine environment. One aspect of their molecular defenses is the SpTransformer (SpTrf) gene family that is upregulated in response to immune challenge. The gene sequences are highly variable both within and among animals and likely encode thousands of SpTrf isoforms within the sea urchin population. The native SpTrf proteins bind foreign targets and augment phagocytosis of a marine Vibrio. A recombinant (r)SpTrf-E1-Ec protein produced by E. coli also binds Vibrio but does not augment phagocytosis. Methods: To address the question of whether other rSpTrf isoforms function as opsonins and augment phagocytosis, six rSpTrf proteins were expressed in insect cells. Results: The rSpTrf proteins are larger than expected, are glycosylated, and one dimerized irreversibly. Each rSpTrf protein cross-linked to inert magnetic beads (rSpTrf::beads) results in different levels of surface binding and phagocytosis by phagocytes. Initial analysis shows that significantly more rSpTrf::beads associate with cells compared to control BSA::beads. Binding specificity was verified by pre-incubating the rSpTrf::beads with antibodies, which reduces the association with phagocytes. The different rSpTrf::beads show significant differences for cell surface binding and phagocytosis by phagocytes. Furthermore, there are differences among the three distinct types of phagocytes that show specific vs. constitutive binding and phagocytosis. Conclusion: These findings illustrate the complexity and effectiveness of the sea urchin innate immune system driven by the natSpTrf proteins and the phagocyte cell populations that act to neutralize a wide range of foreign pathogens.

BACKGROUND: Iatrogenic malnutrition is a significant burden to patients, clinicians, and health care systems. Compared with well-nourished patients, underfed patients (those who receive less than 80% of their daily energy requirement) have more adverse outcomes related to nutritional status. Volume-based protocols allow for catch-up titrations, are consistently superior to rate-based protocols, and can be implemented in most settings. LOCAL PROBLEM: This project was conducted in an 8-bed neuroscience intensive care unit in which up to 41% of patients who required enteral feeding were underfed. METHODS: This quality improvement clinical practice change project used a before-and-after design to evaluate (1) the effect of implementing a volume-based feeding protocol on the delivery of enteral feeds and (2) the effect of a nutrition-based project on staff members' attitudes regarding nutrition in critical care. The effectiveness of a volume-based feeding titration protocol was compared with that of a rate-based feeding protocol for achieving delivery of at least 80% of prescribed nutrition per 24-hour period. Staff members' attitudes were assessed using a survey before and after the project. RESULTS: During 241 enteral feeding days (n = 40 patients), the percentage of delivered enteral feeding volume and the percentage of days patients received at least 80% of the prescribed volume increased after volume-based feeding was implemented. After project implementation, 74 staff members reported increased emphasis on nutrition delivery in their practice and a higher level of agreement that nutrition is a priority when caring for critically ill patients. CONCLUSIONS: Using a volume-based feeding protocol with supplemental staff education resulted in improved delivery of prescribed enteral feeding.

Introduction: B-cell activation triggers the release of endoplasmic reticulum calcium stores through the store-operated calcium entry (SOCE) pathway resulting in calcium influx by calcium release-activated calcium (CRAC) channels on the plasma membrane. B-cell-specific murine knockouts of SOCE do not impact humoral immunity suggesting that alternative channels may be important. Methods: We identified a member of the calcium-permeable transient receptor potential (TRP) ion channel family, TRPV5, as a candidate channel expressed in B cells by a quantitative polymerase chain reaction (qPCR) screen. To further investigate the role of TRPV5 in B-cell responses, we generated a murine TRPV5 knockout (KO) by CRISPR-Cas9. Results: We found TRPV5 polarized to B-cell receptor (BCR) clusters upon stimulation in a PI3K-RhoA-dependent manner. TRPV5 KO mice have normal B-cell development and mature B-cell numbers. Surprisingly, calcium influx upon BCR stimulation in primary TRPV5 KO B cells was not impaired; however, differential expression of other calcium-regulating proteins, such as ORAI1, may contribute to a compensatory mechanism for calcium signaling in these cells. We demonstrate that TRPV5 KO B cells have impaired spreading and contraction in response to membrane-bound antigen. Consistent with this, TRPV5 KO B cells have reduced BCR signaling measured through phospho-tyrosine residues. Lastly, we also found that TRPV5 is important for early T-dependent antigen specific responses post-immunization. Discussion: Thus, our findings identify a role for TRPV5 in BCR signaling and B-cell activation.

OBJECTIVE: The relationship between assisted reproductive techniques (ART) and the risk of asthma and allergic rhinitis (AR) is controversial. Thus, we aimed to investigate the relationship between ART and the risk of asthma and AR in a nationwide, large-scale birth cohort. PATIENTS AND METHODS: This study utilized the National Health Insurance Service data in South Korea to conduct a nationwide, large-scale, population-based birth cohort. We included all infants born between 2017 and 2018. AR, asthma, food allergies, and atopic dermatitis were defined using the International Classification of Diseases tenth edition codes. Asthma was classified as allergic or non-allergic based on accompanying allergic diseases (AR, food allergy, or atopic dermatitis). Using 1:10 propensity score matching, we compared infants conceived through ART with those conceived naturally (non-ART). After matching, logistic regression was used to compare the hazard ratio for asthma and AR between the two groups. RESULTS: We included 543,178 infants [male infants, 280,194 (51.38%)]. After matching, 8,925 and 74,229 infants were selected for the ART and non-ART groups, respectively. The ART group showed a decreased risk of asthma in the offspring [adjusted hazard ratio (aHR), 0.45; 95% confidence interval (CI), 0.41-0.48]. Similarly, for AR, being conceived by ART was associated with a decreased risk of AR (aHR, 0.25; 95% CI, 0.12-0.37). ART offspring showed a decreased risk of asthma and AR in offspring compared to that observed in non-ART offspring. CONCLUSIONS: Our study offers important insights for clinicians, researchers, and parents regarding the health outcomes of ART-conceived infants and enhances our understanding of ART's impact on respiratory health.

INTRODUCTION: Despite substantial research and provision of dental care, significant morbidity remains for children's oral health. Guided by social practice theory (SPT), this research moves away from the often-ineffective focus on changing individual behavior to rethinking the centrality of the social world in promoting or undermining oral health outcomes. We define social practice as a routinized relational activity linking and integrating certain elements (competence, materials, and meanings) into the performance of a practice that is reproduced across time and space. OBJECTIVE: To investigate oral health in preschool children in Perth, Western Australia, using social practice theory. METHODS: With no definitive methodology for investigating SPT, we chose focused ethnography as a problem-focused, context-specific approach using mainly interviews to investigate participants' experience caring for their children's oral health. The focus of analysis was the practice of oral health care, not individual behavior, where themes identified from participants' transcripts were organized into categories of elements and performance. RESULTS: Eleven parents, all of whom were married or partnered, were interviewed in 2021. Findings identified social practices relevant to oral health within parenting and family relations linked to routine daily activities, including shopping, consumption of food and beverages, and toothbrushing. Oral health literacy was reflected in integrating competence, materials, and meanings into performing oral health care, notably preferences for children to drink water over sugary beverages and information often being sourced from social media and mothers' groups rather than health providers. CONCLUSION: Focusing on social practices as the unit of analysis offers a more layered understanding of elements in young children's oral health care that can indicate where the problem may lie. Findings provide an opportunity to consider future research and policy directions in children's oral health. KNOWLEDGE TRANSFER STATEMENT: Examining social practices related to young children's oral health care identifies parents/carers' knowledge about, for example, toothbrushing, the resources required, and why toothbrushing is important. Analyzing these separate elements can reveal both enablers and barriers to oral health care. This provides researchers, clinicians and policymakers an opportunity to focus on not changing individual behavior but understanding how social context impacts parents/carers' capacity to make optimum decisions around young children's oral health.
ABSTRACT
Marine sponges, including the crumb of bread sponge, Hymeniacidon sinapium, display allorejection responses to contact with conspecifics in both experimental and natural settings. These responses have been used to infer immunocompetence in a variety of marine invertebrates. However, larvae and juveniles from several marine sponge species fuse and form chimeras. Some of these chimeras persist, whereas others eventually break down, revealing a period of allogeneic non-responsiveness that varies depending on the species. Alternatively, for H. sinapium, most pairs of sibling post-larvae and juveniles that settle in contact initiate immediate allorecognition and show the same morphological response progression as the adults. This indicates that allorecognition and response occurs during early metamorphosis. Results from H. sinapium and other sponge species, in addition to annotations of sponge genomes, suggest that allorecognition and immunocompetence in sponges are mediated by distinct systems and may become functional at different times during or after metamorphosis for different species. Consequently, allorecognition may not be a good proxy for the onset of immunocompetence.

BACKGROUND: The objective of this study was to evaluate a modern combined video laryngoscopy and flexible fiberoptic bronchoscope approach to placement of a double lumen endobronchial tube and further characterize potential strengths and weaknesses of this approach. METHODS: Retrospective chart review was conducted at our single institution, academic medical center, tertiary-care hospital. Patients aged 18 years of age or older were evaluated who underwent thoracic surgery and one-lung ventilation with placement of a double lumen endobronchial tube using a novel combined video laryngoscopy and flexible fiberoptic bronchoscope approach. No interventions were performed. RESULTS: Demographics and induction and intubation documentation were reviewed for 21 patients who underwent thoracic surgery and one-lung ventilation with placement of a double lumen endobronchial tube using a novel combined video laryngoscopy and flexible fiberoptic bronchoscope approach. First pass success using the combined approach was 86% (18/21). The five patients with an anticipated difficult airway had successful double lumen endobronchial tube placement on the first attempt. There were no instances of desaturation during double lumen endobronchial tube placement. No airway complications related to double lumen endobronchial tube placement were recorded. CONCLUSION: Use of a combined approach employing video laryngoscopy and a flexible fiberoptic bronchoscope may represent a reliable alternative approach to placement of double lumen endobronchial tubes.

The use of radiotherapy has increased in recent years, especially for pelvic neoplasms, and this can result in long-term complications such as recurrent haemorrhagic radiation cystitis (RHC). A 73-year-old male patient presented to a hospital emergency department multiple times with visible haematuria and clots leading to urinary clot retention; he was finally diagnosed with RHC. During the last presentation, the bladder was irrigated continuously with saline using a three-way catheter. During hospitalisation, a cystourethroscopy was performed for bladder evaluation and clot evacuation. Multiple bleeding ulcers were recognised on the bladder wall, biopsies were taken for histopathology, and the ulcers cauterised. Packed red blood cell transfusions were required, and sodium hyaluronate (CystiStat®) bladder instillations were tried. There was no clinical improvement following any of these interventions. In light of the patient's deteriorating condition, cystoscopic application of PuraStat® 3ml was administered, which led to remission of the urinary bleeding in the short term. We continue to monitor the effects in the medium and long term. Based on current data, PuraStat® haemostatic agent therapy may be considered for RHC, when traditional treatments are ineffective or infeasible, potentially eliminating the need for more aggressive therapy such as cystectomy.
ABSTRACT
The SpTransformer (SpTrf) gene family in the purple sea urchin, Strongylocentrotus purpuratus, encodes immune response proteins. The genes are clustered, surrounded by short tandem repeats, and some are present in genomic segmental duplications. The genes share regions of sequence and include repeats in the coding exon. This complex structure is consistent with putative local genomic instability. Instability of the SpTrf gene cluster was tested by 10 days of growth of Escherichia coli harboring bacterial artificial chromosome (BAC) clones of sea urchin genomic DNA with inserts containing SpTrf genes. After the growth period, the BAC DNA inserts were analyzed for size and SpTrf gene content. Clones with multiple SpTrf genes showed a variety of deletions, including loss of one, most, or all genes from the cluster. Alternatively, a BAC insert with a single SpTrf gene was stable. BAC insert instability is consistent with variations in the gene family composition among sea urchins, the types of SpTrf genes in the family, and a reduction in the gene copy number in single coelomocytes. Based on the sequence variability among SpTrf genes within and among sea urchins, local genomic instability of the family may be important for driving sequence diversity in this gene family that would be of benefit to sea urchins in their arms race with marine microbes.

BACKGROUND: Spotting disease infects a variety of sea urchin species across many different marine locations. The disease is characterized by discrete lesions on the body surface composed of discolored necrotic tissue that cause the loss of all surface appendages within the lesioned area. A similar, but separate disease of sea urchins called bald sea urchin disease (BSUD) has overlapping symptoms with spotting disease, resulting in confusions in distinguishing the two diseases. Previous studies have focus on identifying the underlying causative agent of spotting disease, which has resulted in the identification of a wide array of pathogenic bacteria that vary based on location and sea urchin species. Our aim was to investigate the spotting disease infection by characterizing the microbiomes of the animal surface and various tissues. RESULTS: We collected samples of the global body surface, the lesion surface, lesioned and non-lesioned body wall, and coelomic fluid, in addition to samples from healthy sea urchins. 16S rRNA gene was amplified and sequenced from the genomic DNA. Results show that the lesions are composed mainly of Cyclobacteriaceae, Cryomorphaceae, and a few other taxa, and that the microbial composition of lesions is the same for all infected sea urchins. Spotting disease also alters the microbial composition of the non-lesioned body wall and coelomic fluid of infected sea urchins. In our closed aquarium systems, sea urchins contracted spotting disease and BSUD separately and therefore direct comparisons could be made between the microbiomes from diseased and healthy sea urchins. CONCLUSION: Results show that spotting disease and BSUD are separate diseases with distinct symptoms and distinct microbial compositions.

OBJECTIVE: There is a scarcity of literature investigating the impact of the coronavirus disease 2019 (COVID-19) pandemic on long-term trends in health-related quality of life (HrQoL) using large-scale and representative data. Thus, we aimed to investigate the nationwide and long-term trends in quality of life (QoL) using the European Quality of Life- 5 dimensions, 3-level version (EQ-5D-3L) from a Korean representative serial study of 2.8 million people, 2008-2021. SUBJECTS AND METHODS: This Korean study used data on adults between 2008 and 2021 who participated in the Community Health Survey. Timeframes were categorized as COVID-19 mid-pandemic (2021) and pre-pandemic (2008-2019). The mean EQ-5D-3L index for the whole population and subgroups stratified by demographic characters was evaluated for each timeframe, and differences between before and during the COVID-19 pandemic were also analyzed. RESULTS: 2,827,240 adults who responded to the survey, 2008-2021, were eligible for this study. Overall EQ-5D index persistently decreased from 2008-2016, then minimally decreased during the pandemic, still being much higher than forecasted before the COVID-19 pandemic. The reduction in the rate of decline in QoL after the COVID-19 outbreak was especially marked in white-collared, young adults, people with 'good' or 'very good' subjective health, and college-educated or above group. On the other hand, the previously increasing trend of QoL in the elderly group has decelerated during the pandemic, and QoL of the 'very bad' subjective health group recorded the lowest in the whole study period. CONCLUSIONS: The present study investigated the long-term trend of QoL in Korean adults using serial data over the past 14 years, with a special emphasis on comparing the pre- and mid-COVID-19 pandemic periods.

PURPOSE: Accurate prediction of hernia occurrence is vital for surgical decision-making and patient management, particularly in colorectal surgery patients. While a hernia prediction model has been developed, its performance in external populations remain to be investigated. This study aims to validate the existing model on an external dataset of patients who underwent colorectal surgery. METHODS: The "Penn Hernia Calculator" model was externally validated using the Hughes Abdominal Repair Trial (HART) data, a randomized trial comparing colorectal cancer surgery closure techniques. The data encompassed demographics, comorbidities, and surgical specifics. Patients without complete follow-up were omitted. Model performance was assessed using key metrics, including area under the curve (AUC-ROC and AUC-PR) and Brier score. Reporting followed the TRIPOD consensus. RESULTS: An external international dataset consisting of 802 colorectal surgery patients were identified, of which 674 patients with up to 2 years follow-up were included. Average patient age was 68 years, with 63.8% male. The average BMI was 28.1. Prevalence of diabetes, hypertension, and smoking were 15.7%, 16.3%, and 36.5%, respectively. Additionally, 7.9% of patients had a previous hernia. The most common operation types were low anterior resection (35.3%) and right hemicolectomy (34.4%). Hernia were observed in 24% of cases by 2-year follow-up. The external validation model revealed an AUC-ROC of 0.66, AUC-PR of 0.72, and a Brier score of 0.2. CONCLUSION: The hernia prediction model demonstrated moderate performance in the external validation. Its potential generalizability, specifically in those undergoing colorectal surgery, may suggest utility in identifying and managing high-risk hernia candidates.

Background: The primary aim of this study was to determine the epidemiology of lateral-end clavicle fractures in adolescents. The secondary aim was to assess the outcome following non-operative management. Methods: A retrospective review of all adolescent clavicle fractures over a 10-year period was undertaken. Fracture classification, demographics, management, and complications were analysed. Functional outcomes were undertaken with the Quick Disabilities of Arm, Shoulder and Hand and EuroQol five-dimension at mean 8.8 years post-injury. Results: In total, 677 clavicle fractures were analysed, 8.7% were lateral-end fractures (n = 59/677). The median age was 14.6 (range: 13-17) and 92% were male (n = 54/59). The incidence was 0.17 per 100,000 per year. All displaced physeal fractures (Neer IV n = 14) were managed non-operatively and of the six followed-up, all united with good outcomes. The adult type displaced fracture (Neer II) occurred in fifteen fractures, five underwent operative fixation and ten were managed non-operatively with one subsequent nonunion (n = 1/10). Those patients that underwent non-operative management (response n = 5/10, 50%) reported a median Quick Disabilities of Arm, Shoulder and Hand of 2.3 but approximately 40% reported cosmetic and outcome dissatisfaction at long-term follow-up. Conclusion: Displaced Neer II lateral-end clavicle fractures are rare in the adolescent population. Although nonunion is rare, some dissatisfaction with cosmesis persists at long-term follow-up despite good functional outcomes with non-operative management.
