Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer defined by the lack of three key receptors: estrogen, progesterone, and HER2. This lack of receptors makes TNBC difficult to treat with hormone therapy or drugs, and so it is characterised by a poor prognosis compared to other kinds of breast cancer. This study explores photoactive Poly(lactic-co-glycolic acid) (PLGA) nanoparticles as a potential therapeutic strategy for TNBC. The nanoparticles are functionalised with hyaluronic acid (HA) for targeted delivery to CD-44 receptors overexpressed in TNBC cells, especially under hypoxic conditions. Additionally, we co-loaded the nanoparticles with Doxorubicin (Dox) and Indocyanine Green (ICG) to enable combinatorial chemo-photothermal therapy. After carefully optimising the formulation, we propose an effortless and reproducible preparation of the nanodrugs. We demonstrate that HA-conjugated nanoparticles effectively target TNBC cells and inhibit their proliferation while the treatment efficiency is enhanced during near-infrared light irradiation. We also prove that our treatment is effective in a 3D cell culture model, highlighting the importance of tumour architecture and the metabolic stage of the cells in the tumour microenvironment. This approach is promising for a tumour-targeted theragnostic for TNBC with improved efficacy in hypoxic microenvironments., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 The Authors.

Black phosphorus (BP) is one of the most promising nanomaterials for cancer therapy. This 2D material is biocompatible and has strong photocatalytic activity, making it a powerful photosensitiser for combined NIR photothermal and photodynamic therapies. However, the fast degradation of BP in oxic conditions (including biological environments) still limits its use in cancer therapy. This work proposes a facile strategy to produce stable and highly concentrated BP suspensions using lysolipid temperature-sensitive liposomes (LTSLs). This approach also allows for co-encapsulating BP nanoflakes and doxorubicin, a potent chemotherapeutic drug. Finally, we demonstrate that our BP/doxorubicin formulation shows per se high antiproliferative action against an in vitro prostate cancer model and that the anticancer activity can be enhanced through NIR irradiance.

As health systems emerge from the pandemic, academic medical centres are motivated to have a healthy and resilient workforce. In the face of the collective traumas of the pandemic, we took a systems approach to infuse wellness into our culture by modelling collective recovery in a non-traditional town hall. Over a dozen senior leaders, faculty, staff, and students shared their personal experiences in a virtual forum, nearly 1000 attendees communally supported one another. Since the town hall, a recording of the experience has been broadly viewed, messaging from leaders proliferated, and smaller versions of the same exercise were implemented. At a time when academic medical centres faced multiple challenges, we chose to first value the well-being of our staff at a system-wide level. It is our hope that other academic medical centres leverage our story to hold space for the experiences of the people who make their work possible., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2023 The Operational Research Society.)

Background: COVID-19-associated visitor restrictions altered parents' involvement in their infant's care in the neonatal intensive care unit (NICU)., Purpose: The purpose of this article is to explore how restrictions affected parents' perceptions of experience in the NICU and to build a conceptual model of communication flow during times of crisis., Methods: This qualitative study was set in a level III 52-bed NICU. Using data from an open-ended survey question, a multitiered thematic analysis was used., Results: Four broad themes emerged: communication, gratitude, release, and containment of emotionality. These 4 themes interacted codependently and manifested differently as COVID-related visitor policies were put in place. Parents' characterization of communication also varied depending on the visitation policies. Before COVID, parents were more likely to reflect on communication. During COVID, parents expressed more gratitude, while containing negative emotions-sometimes using gratitude to soften the blow of bad feedback., Implications for Practice and Research: Our theoretical model suggests that gratitude may serve as a form of "reciprocal care" to providers during a period of crisis and extreme stress. Use of high-quality communication between providers and parents in the NICU is necessary to understand parental concerns or negative experience., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Cannabidiol (CBD) and Δ 9 -tetrahydrocannabinol (THC) are the two major constituents of cannabis with contrasting mechanisms of action. THC is the major psychoactive, addiction-promoting, and psychotomimetic compound, while CBD may have opposite effects. The brain effects of these drugs alone and in combination are poorly understood. In particular, the striatum is implicated in the pathophysiology of several psychiatric disorders, but it is unclear how THC and CBD influence striato-cortical connectivity., Aims: To examine effects of THC, CBD, and THC + CBD on functional connectivity of striatal sub-divisions (associative, limbic and sensorimotor)., Method: Resting-state functional Magnetic Resonance Imaging (fMRI) was used across two within-subjects, placebo-controlled, double-blind studies, with a unified analysis approach., Results: Study 1 ( N  = 17; inhaled cannabis containing 8 mg THC, 8 mg THC + 10 mg CBD or placebo) showed strong disruptive effects of both THC and THC + CBD on connectivity in the associative and sensorimotor networks, but a specific effect of THC in the limbic striatum network which was not present in the THC + CBD condition. In Study 2 ( N  = 23, oral 600 mg CBD, placebo), CBD increased connectivity in the associative network, but produced only relatively minor disruptions in the limbic and sensorimotor networks., Outcomes: THC strongly disrupts striato-cortical networks, but this effect is mitigated by co-administration of CBD in the limbic striatum network. Oral CBD administered has a more complex effect profile of relative increases and decreases in connectivity. The insula emerges as a key region affected by cannabinoid-induced changes in functional connectivity, with potential implications for understanding cannabis-related disorders, and the development of cannabinoid therapeutics.

Rationale: There is growing interest in the therapeutic potential of cannabidiol (CBD) across a range of psychiatric disorders. CBD has been found to reduce anxiety during experimentally induced stress in anxious individuals and healthy controls. However, the mechanisms underlying the putative anxiolytic effects of CBD are unknown., Objectives: We sought to investigate the behavioural and neural effects of a single dose of CBD vs. placebo on a range of emotion-related measures to test cognitive-mechanistic models of its effects on anxiety., Methods: We conducted a randomised, double-blind, placebo-controlled, crossover, acute oral challenge of 600 mg of CBD in 24 healthy participants on emotional processing, with neuroimaging (viewing emotional faces during functional magnetic resonance imaging) and cognitive (emotional appraisal) measures as well as subjective response to experimentally induced anxiety., Results: CBD did not produce effects on brain responses to emotional faces and cognitive measures of emotional processing, or modulate experimentally induced anxiety, relative to placebo., Conclusions: Given the rising popularity of CBD for its putative medical benefits, these findings question whether further research is warranted to investigate the clinical potential of CBD for the treatment of anxiety disorders., (© 2022.

Background: Burnout, often regarded as an individual failing, rather than a systemic one, negatively impacts quality of care, patient safety and healthcare costs. Focusing on improving well-being can help mitigate burnout. This study examined protective factors that promote well-being and professional fulfillment in surgeons., Methods: Using a purposive sample, 32 semi-structured 30-60-min interviews were conducted with surgeons of varying sub-specialties and rank. Abductive exploratory analysis was used to code and interpret interview transcripts and to build a conceptual model of surgeon well-being., Results: Emergent protective factors were placed into one of three levels of implementation: individual, team-level, and institutional (figure). Individual factors for well-being included autonomy and adequate time to pursue non-clinical endeavors. Team-level factors consisted of adaptability, boundaries, and cohesion. Institutional factors related to diversifying performance evaluations and celebrating and recognizing individual value and contributions., Conclusions: The conceptual model developed from the results of this study highlights factors important to surgeons' professional well-being. This model can be used to guide quality improvement efforts., (Published by Elsevier Inc.)

Background: Though clinical researchers have begun to use social media platforms to recruit participants, social media influencers are innovative community connectors to further expand recruitment reach, especially in hard-to-reach populations., Objectives: The purpose of this methods article is to provide a step-by-step guide for engaging social media influencers for virtual participant recruitment., Methods: There are multiple steps for researchers to follow, including preplanning, institutional review board approval, engaging with influencers, the pitch, the post, and results dissemination., Discussion: Engaging social media influencers to recruit for clinical research demonstrates great potential to increase access to hard-to-reach populations. Several methodological considerations remain, and this article shares both opportunities and challenges to guide researchers in this technique., Competing Interests: The authors have no conflicts of interest to report., (Copyright © 2021 Wolters Kluwer Health, Inc.

Historically, diabetes identity has been examined at the individual level as it relates to clinical outcomes and self-management practices. Yet, identity is not experienced as an individually isolated phenomenon. The purpose of this study is twofold: (a) examine the social meaning of diabetes identity and (b) formulate a theoretical model of diabetes identity through a sociopolitical lens. Adults living with diabetes engaged in a diabetes online community ( N = 20) participated in a 60-minute semi-structured interview focused on social diabetes experiences and diabetes identity. Seven themes emerged related to illness, individuation, and culture, resulting in a novel theoretical model of diabetes identity: willingness to identify, tales of the un-sick, legends of the responsible, a tradition of change-making, sense of sameness, mystification of difference, and diabetes as a unifying social category. Our study extends previous literature focused on self-management practices and compliance, resulting in a theoretical model of diabetes identity centered around social change.

Background: Patients with diabetes have developed innovative do-it-yourself (DIY) methods for adapting existing medical devices to better fit individual needs., Method: A multiple method study used Symplur Analytics to analyze aggregated Twitter data of #WeAreNotWaiting and #OpenAPS tweets between 2014 and 2017 to examine DIY patient-led innovation. Conversation sentiment was examined between diabetes stakeholders to determine changes over time. Two hundred of the most shared photos were analyzed to understand visual representations of DIY patient-led innovations. Finally, discourse analysis was used to identify the personas who engage in DIY patient-led diabetes technologies activities and conversations on Twitter., Results: A total of 7886 participants who generated 46 578 tweets were included. Sentiment analysis showed that 82%-85% of interactions around DIY patient-led innovation was positive among patient/caregiver and physician groups. Through photo analysis, five content themes emerged: (1) disseminating media and conference coverage, (2) showcasing devices, (3) celebrating connections, (4) providing instructions, and (5) celebrating accomplishments. Six personas emerged across the overlapping userbase: (1) fearless leaders, (2) loopers living it up, (3) parents on a mission, (4) the tech titans, (5) movement supporters, and (6) healthcare provider advocates. Personas had varying goals and behaviors within the community., Conclusions: #WeAreNotWaiting and #OpenAPS on Twitter reveal a fast-moving patient-led movement focused on DIY patient innovation that is further mobilized by an expanding and diverse userbase. Further research is indicated to bring technology savvy persons with diabetes into conversation with healthcare providers and researchers alike.

Background: The cost of diabetes medications and supplies is rising, resulting in access challenges. This study assessed the prevalence of and factors predicting underground exchange activities-donating, trading, borrowing, and purchasing diabetes medications and supplies., Research Design and Methods: A convenience sample of people affected by diabetes was recruited online to complete a survey. Mixed method analysis was undertaken, including logistic regression to examine the relationship between self-reported difficulty purchasing diabetes medications and supplies and engagement in underground exchange activity. Thematic qualitative analysis was used to examine open-text responses., Results: Participants ( N = 159) self-reported engagement in underground exchange activities, including donating (56.6%), donation receiving (34.6%), trading (23.9%), purchasing (15.1%), and borrowing (22%). Such activity took place among a variety of individuals, including friends, family, coworkers, online acquaintances and strangers. Diabetes-specific financial stress predicted engagement in trading diabetes mediations or supplies (OR 6.3, 95% CI 2.2-18.5) and receiving donated medications or supplies (OR 2.8, 95% CI 1.1-7.2). One overarching theme, unmet needs, and three subthemes emerged: (1) factors influencing underground exchange activity, (2) perceived benefits of underground exchange activity, and (3) perceived consequences of underground exchange activity., Conclusion: Over half of the participants in this study engaged in underground exchange activities out of necessity. Providers must be aware about this underground exchange and inquire about safety and possible alternative resources. There is an urgent need to improve access to medications that are essential for life. Our study points to a failure in the US healthcare system since such underground exchanges may not be necessary if medications and supplies were accessible.

Background: Cannabidiol (CBD) is being investigated as a potential treatment for several medical indications, many of which are characterised by altered memory processing. However, the mechanisms underlying these effects are unclear., Aims: Our primary aim was to investigate how CBD influences cerebral blood flow (CBF) in regions involved in memory processing. Our secondary aim was to determine if the effects of CBD on CBF were associated with differences in working and episodic memory task performance., Methods: We used a randomised, crossover, double-blind design in which 15 healthy participants were administered 600 mg oral CBD or placebo on separate days. We measured regional CBF at rest using arterial spin labelling 3 h after drug ingestion. We assessed working memory with the digit span (forward, backward) and n-back (0-back, 1-back, 2-back) tasks, and we used a prose recall task (immediate and delayed) to assess episodic memory., Results: CBD increased CBF in the hippocampus (mean (95% confidence intervals) = 15.00 (5.78-24.21) mL/100 g/min, t 14 = 3.489, Cohen's d = 0.75, p = 0.004). There were no differences in memory task performance, but there was a significant correlation whereby greater CBD-induced increases in orbitofrontal CBF were associated with reduced reaction time on the 2-back working memory task ( r = -0.73, p = 0.005)., Conclusions: These findings suggest that CBD increases CBF to key regions involved in memory processing, particularly the hippocampus. These results identify potential mechanisms of CBD for a range of conditions associated with altered memory processing, including Alzheimer's disease, schizophrenia, post-traumatic stress disorder and cannabis-use disorders.

Importance: A key objective of the Americans With Disabilities Act of 1990 (ADA) is community integration; yet, nearly 30 yr later, little is known about the participation of people with disabilities who transition from institutions to the community., Objective: To understand how people with disabilities describe full participation after transitioning from an institution to the community and to identify environmental barriers and facilitators to participation during and after this transition., Design: The ADA-Participatory Action Research Consortium (ADA-PARC), a collaboration among researchers, people with disabilities, and community organizations, is implementing a multimethod, participatory action research study of participation among people with disabilities posttransition. This article presents qualitative findings from semistructured interviews collected as part of the larger ADA-PARC project., Setting: ADA-PARC community partners across the United States., Participants: One hundred fifty-three adults with disabilities., Outcomes and Measures: We used a semistructured interview guide to ask participants about their experiences during and after transition to the community., Results: We identified four themes: (1) the process of transition as ongoing rather than a single event, (2) access to everyday occupations as full participation and what fully represents "living a life," (3) environmental barriers to participation, and (4) social identity as participation as the transformative process of moving from the disempowering isolation of the institution to being integrated into the community., Conclusions and Relevance: As people with disabilities transition into community settings, they require ongoing supports to facilitate their full, long-term participation., What This Article Adds: People with disabilities reported that transitioning from institutions to the community was itself not enough to support their full community participation; rather, they viewed transition as an ongoing process, and they needed services and supports to fully participate. Occupational therapy practitioners working in institutional and community settings can partner with local disability advocacy communities to support their clients' sense of identity and self-confidence during and after transition to the community., (Copyright © 2020 by the American Occupational Therapy Association, Inc.)

Purpose: The purpose of this study is to report a systematic review of reviews of evidence and gaps focused on in-person and technology-mediated diabetes peer support and its impact on clinical, behavioral, and psychosocial outcomes., Methods: We conducted a systematic review of reviews in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Reviews published in English from December 1978 through December 2018 examining clinical, behavioral, and psychosocial outcomes were included. The search yielded 167 reviews that were examined for inclusion/exclusion criteria., Results: Nine systematic reviews and meta-analyses meeting criteria were included. Findings suggest peer support interventions can have a positive impact on clinical (A1C, blood pressure, cholesterol, weight), behavioral (diabetes knowledge, being active, healthy eating, medication management, self-management, self-efficacy, empowerment), and psychosocial (social support, health and diabetes distress, depression, quality of life) outcomes. Research gaps exist related to understanding the effects of emerging technology-mediated peer support modalities and the effects of peer support on gestational diabetes., Conclusion: Many clinical, behavioral, and psychosocial benefits related to in-person and technology-mediated peer support exist. Diabetes care and education specialists should incorporate and recommend peer support resources for people with diabetes.

Purpose: Increasing attention is being given to the challenges and emotional toll of managing diabetes. This Perspectives in Practice details the specialty's guiding documents for initial and ongoing support. It also defines various types of social support, including peer support, for optimal diabetes care. Focusing on peer support, this paper provides a review of the body of evidence demonstrating the value of peer support to improve clinical and behavioral outcomes. To achieve positive outcomes, it is optimal for people with diabetes to have access to ongoing support from their health care provider, including diabetes care and education specialists. They should also be made aware of, and given referral to options and opportunities for peer support. This Perspectives in Practice concludes with a call to action for diabetes care and education specialists to deliver to integrate and promote the value of peer support in the care they provide., Conclusion: Managing diabetes during the stages and ages of life is chronically challenging and complex. Various types of support offered by health care providers, including diabetes care and education specialists and others in the person's social support milieu, can positively affect emotional well-being. Health care providers should routinely assess their client's social supports and refer the person with diabetes and/or their caregivers to evidence-based types of peer support mutually determined to be of most value. Diabetes care and education specialists should increase their awareness of opportunities to integrate the value of and referral to peer support in their counseling and to gain greater insight into the diabetes-lived experience.

Background: Individuals with diabetes are using online resources to engage in diabetes online communities to find diabetes-related support and information. The benefits and consequences of DOC (diabetes online community) use are unclear. This scoping review aims to map existing research focused on organic DOCs in which individuals affected by diabetes are interacting with peers., Method: A scoping review was conducted to comprehensively report and synthesize relevant literature published prior to 2018. Attention was paid to variations in study design, DOC user and platform characteristics, and potential or actual benefits and consequences., Results: Of the 14 486 titles identified, 47 articles met the inclusion criteria and were included in this scoping review. No overt definition of the DOC could be identified. Perceived or actual benefits associated with DOC use can be broadly categorized as clinical, behavioral, psychosocial and community outcomes. Perceived, potential, or actual consequences associated with DOC use were categorized as quality of information, risky behavior exploration, acute concerns, psychosocial, privacy, and inactivity., Conclusions: The results of this review strongly suggest DOC use is highly beneficial with relatively few negative consequences. DOC use is an emerging area of research and research gaps exist. Future research should seek to identify benefits and consequences to DOC use in experimental trials.
