Mental health challenges among adolescents living with HIV
Introduction: Mental health is a critical and neglected global health challenge for adolescents infected with HIV. The prevalence of mental and behavioural health issues among HIV-infected adolescents may not be well understood or addressed as the world scales up HIV prevention and treatment for adolescents. The objective of this narrative review is to assess the current literature related to mental health challenges faced by adolescents living with HIV, including access to mental health services, the role of mental health challenges during transition from paediatric to adult care services and responsibilities, and the impact of mental health interventions., Methods: For each of the topics included in this review, individual searches were run using Medline and PubMed, accompanied by scans of bibliographies of relevant articles. The topics on which searches were conducted for HIV-infected adolescents include depression and anxiety, transition from paediatric to adult HIV care and its impact on adherence and mental health, HIV-related, mental health services and interventions, and the measurement of mental health problems. Articles were included if the focus was consistent with one of the identified topics, involved HIV-infected adolescents, and was published in English., Results and Discussion: Mental and behavioural health challenges are prevalent in HIV-infected adolescents, including in resource-limited settings where most of them live, and they impact all aspects of HIV prevention and treatment. Too little has been done to measure the impact of mental health challenges for adolescents living with HIV, to evaluate interventions to best sustain or improve the mental health of this population, or to create healthcare systems with personnel or resources to promote mental health., Conclusions: Mental health issues should be addressed proactively during adolescence for all HIV-infected youth. In addition, care systems need to pay greater attention to how mental health support is integrated into the care management for HIV, particularly throughout lifespan changes from childhood to adolescence to adulthood. The lack of research and support for mental health needs in resource-limited settings presents an enormous burden for which cost-effective solutions are urgently needed
Understanding University Support for Suicide Bereavement and Bereaved Experiences: A Phenomenological Study
In recent years, a multitude of literature have discussed the turbulent nature for young adults to navigate the difficulties of suicide bereavement with lack of support. This experience can be further cumbersome when the bereavement is co-occurring within an academic profession, such as attending university. This study explored three participants experience of suicide bereavement support at a university level, utilizing a phenomenological arts-based approach for inquiry. Data analysis revealed eight common themes that reflect the university students\u27 lived experiences of the phenomenon discussed: Acknowledgment of the communicated loss by faculty, provision of academic support, lack/absence of practice, reluctance, emotional response, non-faculty support, recall, omission. The findings within this study highlight the unique nature of arts expression and the use of it as a communicative tool to those experiencing a death loss. Results suggest a reluctance to disclose for fear of a further loss of professionalism within the University setting and the absence of a solidified grievance plan that left individuals feeling further unsupported. Furthermore, individuals spoke to a heightened need for meaning making of the experience to facilitate the bereavement process and a reliance on the self rather than community due to previous fears of disclosure. Our understanding of suicide bereavement would benefit from an inclusion of non-art affiliated participants, a wider sample size and individuals that associate outside of the female identification for a more diverse range of experiences
DNA-Mediated Excitonic Upconversion FRET Switching
Excitonics is a rapidly expanding field of nanophotonics in which the harvesting of photons, ensuing creation and transport of excitons via Förster resonant energy transfer (FRET), and subsequent charge separation or photon emission has led to the demonstration of excitonic wires, switches, Boolean logic and light harvesting antennas for many applications. FRET funnels excitons down an energy gradient resulting in energy loss with each step along the pathway. Conversely, excitonic energy upconversion via upconversion nanoparticles (UCNPs), although currently inefficient, serves as an energy ratchet to boost the exciton energy. Although FRET-based upconversion has been demonstrated, it suffers from low FRET efficiency and lacks the ability to modulate the FRET. We have engineered an upconversion FRET-based switch by combining lanthanide-doped UCNPs and fluorophores that demonstrates excitonic energy upconversion by nearly a factor of 2, an excited state donor to acceptor FRET efficiency of nearly 25%, and an acceptor fluorophore quantum efficiency that is close to unity. These findings offer a promising path for energy upconversion in nanophotonic applications including artificial light harvesting, excitonic circuits, photovoltaics, nanomedicine, and optoelectronics
Transitioning HIV-infected adolescents to adult care at 14 clinics across the United States: Using adolescent and adult providers’ insights to create multi-level solutions to address transition barriers
HIV-infected adolescents have disproportionately low rates of care retention and viral suppression. Approximately half disengage from care while transitioning to adult clinics, in part due to fragmented care systems and lack of streamlined protocols. We conducted 58 qualitative interviews with social service and health care providers across 14 Adolescent Trials Network clinics (n=28) and 20 adult clinics that receive transitioning adolescents (n=30) from August 2015 – June 2016. We used the constant comparative approach to examine processes, barriers, and facilitators of adult care transition. Transition barriers coalesced around three levels. Structural: insurance eligibility, transportation, and HIV-related stigma; Clinical: inter-clinic communication, differences in care cultures, and resource/personnel limitations; and Individual: adolescents’ transition readiness and developmental capacity. Staff-initiated solutions (e.g., grant-funded transportation) were often unsustainable and applied individual-level solutions to structural-level barriers. Comprehensive initiatives, which develop collaborative policies and protocols that support providers’ ability to match the solution and barrier level (i.e., structural-to-structural), are sorely needed. These initiatives should also support local systematic planning to facilitate inter-clinic structures and communication. Such approaches will help HIV-infected adolescents transition to adult care and improve long-term health outcomes
Physical therapy Consultation in the Emergency Department For Older adults With Falls: a Qualitative Study
OBJECTIVES: Little is known about current practices in consulting physical therapy (PT) in the emergency department (ED) for older adults with falls, a practice that can reduce fall-related ED revisits. This qualitative study aimed to understand perspectives of ED staff about ED PT consultation for older adults with falls and fall-related complaints, specifically regarding perceived value and associated challenges and strategies.
METHODS: We performed focus groups and key informant interviews with emergency physicians, advanced practice clinicians, nurses, physical therapists, occupational therapists, and technicians who perform ED geriatric screenings. We used rapid qualitative analysis to identify common themes related to decisions to consult PT from the ED, perceived value of PT, and common challenges and strategies in ED PT consultation.
RESULTS: Twenty-five participants in 4 focus groups and 3 interviews represented 22 distinct institutions with ED PT consultation available for older adults with falls. About two thirds of EDs represented relied on clinician gestalt to request PT consultation (n = 15, 68%), whereas one third used formal consultation pathways (n = 7, 32%). Participants valued physical therapists\u27 expertise, time, and facilitation of hospital throughput by developing safe discharge plans and contact with patients to improve outpatient follow-up. Common challenges included limited ED PT staffing and space for PT evaluations; strategies to promote ED PT consultation included advocating for leadership buy-in and using ED observation units to monitor patients and avoid admission until PT consultation was available.
CONCLUSION: ED PT consultation for older adults with falls may benefit patients, ED staff, and hospital throughput. Uncertainty remains over whether geriatric screening-triggered consultation versus emergency clinician gestalt successfully identifies patients likeliest to benefit from ED PT evaluation. Leadership buy-in, designated consultation space, and formalized consultation pathways are strategies to address current challenges in ED PT consultation
Nativity Differences in Stress among Asian and Pacific Islander American Women
According to the Stress Process Theory, people who are marginalized in society encounter more stress than those in more advantaged positions. Immigrants are one such marginalized group in the United States (US) who may experience greater psychological stress than their US-born counterparts due to (1) severing of social ties; (2) social disadvantage and marginalization; and (3) adaptation to a new environment. This study examines the disparity in stress by nativity, and how social factors contribute to this disparity for Asian and Pacific Islander (API) women. Data come from the Asian Community Health Initiative, which included a sample of 291 foreign-born and 155 US-born API women in the San Francisco Bay Area. Multivariable linear regression was used to estimate associations between nativity status and stress, measured using the Cohen Perceived Stress Scale, accounting for various social stressors. Foreign-born women had higher levels of stress compared to US-born. Stress was greater among women experiencing fewer socioeconomic resources, more discrimination, more acculturative stress, and low English proficiency. English proficiency accounted for much of the disparity in stress between foreign-born and US-born API women. This study contributes to our understanding of how stress among APIs is influenced by social disadvantage and marginalization in US society. Future research should further study how aspects of the immigrant experience are associated with stress among APIs over time
Impact of early pericardial fluid chymase activation after cardiac surgery
INTRODUCTION: Chymase is a highly destructive serine protease rapidly neutralized in the circulation by protease inhibitors. Here we test whether pericardial fluid (PCF) chymase activation and other inflammatory biomarkers determine intensive care unit length of stay, and explore mechanisms of chymase delivery by extracellular vesicles to the heart.
METHODS: PCF was collected from adult patients (17 on-pump; 13 off-pump) 4 h after cardiac surgery. Extracellular vesicles (EVs) containing chymase were injected into Sprague-Dawley rats to test for their ability to deliver chymase to the heart.
RESULTS: The mean intensive care unit (ICU) stay and mean total length of stay was 2.17 ± 3.8 days and 6.41 ± 1.3 days respectively. Chymase activity and 32 inflammatory markers did not differ in on-pump vs. off-pump cardiac surgery. Society of Thoracic Surgeons Predicted Risk of Morbidity and Mortality Score (STS-PROM), 4-hour post-surgery PCF chymase activity and C-X-C motif chemokine ligand 6 (CXCL6) were all independent predictors of ICU and total hospital length of stay by univariate analysis. Mass spectrometry of baseline PCF shows the presence of serine protease inhibitors that neutralize chymase activity. The compartmentalization of chymase within and on the surface of PCF EVs was visualized by immunogold labeling and transmission electron microscopy. A chymase inhibitor prevented EV chymase activity (0.28 fmol/mg/min vs. 14.14 fmol/mg/min). Intravenous injection of PCF EVs obtained 24 h after surgery into Sprague Dawley rats shows diffuse human chymase uptake in the heart with extensive cardiomyocyte damage 4 h after injection.
DISCUSSION: Early postoperative PCF chymase activation underscores its potential role in cardiac damage soon after on- or off-pump cardiac surgery. In addition, chymase in extracellular vesicles provides a protected delivery mechanism from neutralization by circulating serine protease inhibitors
