Families can experience grief when they lose a loved one to incarceration. Although there has not been a death, the removal of a family member from day-to-day life and the uncertainty and stigma surrounding incarceration pose major challenges. We applied consensual qualitative research methods to understand the unique grief experience that adult children have when a parent is incarcerated. Our findings elaborate on the impacts of the loss, the complicating factors of stigma and disenfranchisement, as well as how individuals have made meaning and pursued healing from this experience over time...

This study aims to examine the play between various archwires and bracket systems, exploring potential variations in angle values for specific torque and torque values for a given angle along different bracket systems. Therefore, seven brackets systems were evaluated in conjunction with different stainless steel archwires of varying dimensions (0.016″ × 0.022″, 0.018″ × 0.025″, and 0.019″ × 0.025″). Biomechanical behavior during torque development and transmission was assessed using a six-component force/torque sensor...

Identification of immunogenic cancer neoantigens as targets for therapy is challenging. Here, we integrate cancer whole genome and long-read transcript sequencing to identify the collection of novel open reading frame peptides (NOPs) expressed in tumors, termed the framome. NOPs represent tumor-specific peptides that are different from wild-type proteins and may be strongly immunogenic. We describe an uncharacterized class of hidden NOPs, which derive from structural genomic variants involving an upstream protein coding gene driving expression and translation of non-coding regions of the genome downstream of a rearrangement breakpoint...

Hydrogen/deuterium exchange-mass spectrometry (HDX-MS) has emerged as a powerful tool to probe protein dynamics. As a bottom-up technique, HDX-MS provides information at peptide-level resolution, allowing structural localization of dynamic changes. Consequently, the HDX-MS data quality is largely determined by the number of peptides that are identified and monitored after deuteration. Integration of ion mobility (IM) into HDX-MS workflows has been shown to increase the data quality by providing an orthogonal mode of peptide ion separation in the gas phase...

Interparental conflict is known to negatively impact child well-being, including behavioral and physiological well-being. Children's empathy - that is, vicariously experiencing others' emotions - may increase children's sensitivity to and the biological repercussions of interparental conflict. Although empathy represents a valued trait and is an important part of socioemotional development, its influence on children's physical health is unknown. This study examined whether empathy moderates the association between perceived interparental conflict and both child systemic inflammation and parent-rated overall child health in a sample of children between the ages of seven to nine...

OBJECTIVES: To compare self-reported pain levels across various treatment phases using passive self-ligating (Damon) and conventional (Victory) standardized fixed appliance systems. MATERIALS AND METHODS: Adolescents (12-17 years old) with crowding and displaced teeth, planned for non-extraction treatment, were recruited from four orthodontic clinics. They were randomized into stratified blocks (1:1 ratio) using concealed allocation to receive Damon Q™ (34 boys, 28 girls) or Victory™ (39 boys, 31 girls)...

STUDY DESIGN: A retrospective review was conducted of all patients with mandibular fractures who were evaluated by plastic surgery at a Level I trauma center between January 1, 2017 and May 1, 2020. Data including demographic characteristics, mechanism of injury, type of presentation (e.g., primary or transfer), treatment plan, and time to intervention were recorded. OBJECTIVE: Mandibular fractures are common traumatic injuries. Because these injuries are managed by surgical specialists, these patients are often emergently transferred to tertiary care hospitals...

MRI-guided neuro interventions require rapid, accurate, and reproducible segmentation of anatomical brain structures for identification of targets during surgical procedures and post-surgical evaluation of intervention efficiency. Segmentation algorithms must be validated and cleared for clinical use. This work introduces a methodology for shape-constrained deformable brain segmentation, describes the quantitative validation used for its clinical clearance, and presents a comparison with manual expert segmentation and FreeSurfer, an open source software for neuroimaging data analysis...

VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome, caused by somatic mutations in UBA1, is an autoinflammatory disorder with diverse systemic manifestations. Thrombosis is a prominent clinical feature of VEXAS. The risks factors and frequency of thrombosis in VEXAS are not well described, due to the disease's new discovery and paucity of large databases. We evaluated 119 VEXAS patients for venous and arterial thrombosis and correlated their presence with clinical outcomes and survival...

BACKGROUND: An app providing material for education and entertaining is a possible way to support patients and healthcare providers in achieving person-centered care. METHODS: An app tailored on the Fondazione Toscana Gabriele Monasterio (FTGM), a research hospital treating cardiac and lung disorders, was created. A pilot evaluation project was conducted on consecutive patients hospitalized for heart or lung disorders. Patients were asked to complete an assessment questionnaire...

BACKGROUND: Nearly half of patients transferred from non-trauma to trauma centres have minor injuries. The transfer of patients with minor injuries to trauma centres is not associated with any known patient benefit and represents an opportunity to reduce healthcare costs and improve patient experience. In this study, we evaluated the relationship between hospital resources and overtriage, with the objective of identifying targets for system-level intervention. METHODS: We conducted a population-based cohort study of adults, age ≥ 16, presenting with minor injuries to non-trauma centres in Ontario, Canada (2009-2020)...

Cybermedical systems that regulate patient clotting in real time with personalized blood product delivery will improve treatment outcomes. These systems will harness popular viscoelastic assays of clot strength such as thromboelastography (TEG), which help evaluate coagulation status in numerous conditions: major surgery (e.g., heart, vascular, hip fracture, and trauma); liver cirrhosis and transplants; COVID-19; ICU stays; sepsis; obstetrics; diabetes; and coagulopathies like hemophilia. But these measurements are time-consuming, and thus impractical for urgent care and automated coagulation control...

OBJECTIVE: Comparison of pain levels of patients treated with 2 different passive self-ligating bracket systems right after initial archwire placement. METHODS: A total of 34 patients with mild crowding were allocated randomly to 2 groups to be treated using 2 different self-ligating brackets. 0.014 inch copper nitinol and 0.014 inch superelastic nitinol archwires were selected as the initial archwire for Damon Q and SmartClip SL3 systems respectively. Seven page questionnaires that consisted of 3 visual analogue scales were handled to patients to mark their pain levels while chewing, biting with anterior teeth, and biting with posterior teeth at 2nd hour, 6th hour, 2nd day, 3rd day, and 7t h day time intervals...

In a randomized, pre-post intervention study, we evaluated the influence of a large language model (LLM) generative AI system on accuracy of physician decision-making and bias in healthcare. 50 US-licensed physicians reviewed a video clinical vignette, featuring actors representing different demographics (a White male or a Black female) with chest pain. Participants were asked to answer clinical questions around triage, risk, and treatment based on these vignettes, then asked to reconsider after receiving advice generated by ChatGPT+ (GPT4)...

PURPOSE: The WHO emphasises that rehabilitation services must be integrated into primary healthcare as an inherent part of universal health coverage. However, there is limited research on the integration of rehabilitation services in primary healthcare in low- and middle-income countries. The purpose of this paper is to identify and describe the literature on service guidelines, models, and protocols that support the integration of rehabilitation services in primary healthcare in the BRICS countries (Brazil, Russia, India, China, and South Africa)...

Resistance training not only can improve or maintain muscle mass and strength, but also has favorable physiological and clinical effects on cardiovascular disease and risk factors. This scientific statement is an update of the previous (2007) American Heart Association scientific statement regarding resistance training and cardiovascular disease. Since 2007, accumulating evidence suggests resistance training is a safe and effective approach for improving cardiovascular health in adults with and without cardiovascular disease...

BACKGROUND: Injectable opioid agonist treatment (iOAT) has proven to be a safe and effective treatment option for severe opioid use disorder (OUD). Yet, iOAT is often isolated from other health and social services. To align with a person-centered care approach, iOAT can be embedded in sites that combine systems and services that have been historically fragmented and that address multiple comorbidities (integrated care sites). The present study investigates the addition of iOAT at an integrated care in Vancouver, British Columbia...

OBJECTIVE(S): This study aims to evaluate the influence of the piezocision surgery in the orthodontic biomechanics, as well as in the magnitude and direction of tooth movement in the mandibular arch using novel artificial intelligence (AI)-automated tools. MATERIALS AND METHODS: Nineteen patients, who had piezocision performed in the lower arch at the beginning of treatment with the goal of accelerating tooth movement, were compared to 19 patients who did not receive piezocision...

Osteosarcoma is the most common bone sarcoma in children and young adults. While universally delivered, chemotherapy only benefits roughly half of patients with localized disease. Increasingly, intratumoral heterogeneity is recognized as a source of therapeutic resistance. In this study, we develop and evaluate an in vitro model of osteosarcoma heterogeneity based on phenotype and genotype. Cancer cell populations vary in their environment-specific growth rates and in their sensitivity to chemotherapy. We present the genotypic and phenotypic characterization of an osteosarcoma cell line panel with a focus on co-cultures of the most phenotypically divergent cell lines, 143B and SAOS2...

Clinical severity scores facilitate comparisons to understand risk factors for severe illness. For the 2022 multinational monkeypox Clade IIb virus outbreak, we developed a 7-item mpox severity scoring system (MPOX-SSS) with initial variables refined based on data availability and parameter correlation. Application of MPOX-SSS to the first 200 patients diagnosed with mpox revealed higher scores in those treated with tecovirimat, presenting >3 days after symptom onset and with CD4 counts <200 cells/mm3 ...
