ABSTRACT

BACKGROUND: People who are insecurely housed and use drugs are disproportionately affected by drug poisonings. Nurses are uniquely positioned to utilize harm reduction strategies to address the needs of the whole person. Needle debris encompasses drug paraphernalia discarded in public spaces. Studying needle debris provides a strategic opportunity to identify where drugs are being used and target public health strategies accordingly. AIM: Our aim in this article is to illustrate how spatial video geonarratives (SVG) combined GPS technology interviews, and videos of locations with needle debris, can elicit valuable data for nursing research. METHODS: Using SVG required knowledge of how to collect data wearing cameras and practice sessions were necessary. A Miufly camera worn at waist height on a belt provided the stability to walk while interviewing stakeholders. We wore the cameras and conducted go-along interviews with outreach workers, while filming the built environment. Upon completion of data collection, both the interview and GPS information were analysed using Wordmapper software. CONCLUSIONS: This methodology resulted in data presented uniquely in both a visual map and narrative. These data were richer than if a single modality had been used. These data highlighted specific contextual factors that were related to the location of needle debris, which created opportunities for nursing interventions to support people experiencing vulnerability.

ABSTRACT

The emergence of COVID-19 (SARS-CoV-2) has introduced significant global challenges for healthcare systems, healthcare professionals and patients. This current climate creates an opportunity to learn from equitable health systems and move toward making fundamental changes to healthcare systems. Our ethnographic analysis of Wakanda's healthcare system in Black Panther, from the Marvel Cinematic Universe, offers opportunities for system-level transformation across healthcare settings. We propose four healthcare system themes within the context of Wakandan identity: (1) technology as an instrument (blending bodies and technology, blending technology with tradition); (2) reimagining medication; (3) warfare and rehabilitation; and (4) preventative approaches to health (prioritising collective health, deprofessionalisation of healthcare services). The preceding themes represent core elements of Wakandan health systems that allow the people of Wakanda to thrive. Wakandans retain a strong identity and cultural traditions while embracing modern technologies. We found that effective upstream approaches to health for all are embedded in anti-colonial philosophies. Wakandans embrace innovation, embedding biomedical engineering and continuous improvement into care settings. For global health systems under strain, Wakanda's health system identifies equitable possibilities for system change, reminding us that culturally relevant prevention strategies can both decrease pressure on health services and allow all people to thrive.

ABSTRACT

Across species, including humans, elevated levels of brain estrogen receptor (ER) α are associated with enhanced cognitive aging, even in the absence of circulating estrogens. In rodents, short-term estrogen treatment, such as that commonly used in the menopausal transition, results in long-term increases in ERα levels in the hippocampus, leading to enhanced memory long after termination of estrogen treatment. However, mechanisms by which increased levels of brain ERα enhances cognitive aging remain unclear. Here we demonstrate in aging female rats that insulin-like growth factor-1 (IGF-1), which can activate ER via ligand-independent mechanisms, requires concomitant synthesis of brain-derived neuroestrogens to phosphorylate ERα via MAPK signaling, ultimately resulting in enhanced memory. In a rat model of menopause involving long-term ovarian hormone deprivation, hippocampal neuroestrogen activity decreases, altering IGF-1 activity and resulting in impaired memory. However, this process is reversed by short-term estradiol treatment. Forty days of estradiol exposure following ovariectomy results in maintenance of neuroestrogen levels that persist beyond the period of hormone treatment, allowing for continued interactions between IGF-1 and neuroestrogen signaling, elevated levels of hippocampal ERα, and ultimately enhanced memory. Collectively, results demonstrate that short-term estradiol use following loss of ovarian function has long-lasting effects on hippocampal function and memory by dynamically regulating cellular mechanisms that promote activity of ERα in the absence of circulating estrogens. Translational impacts of these findings suggest lasting cognitive benefits of short-term estrogen use near menopause and highlight the importance of hippocampal ERα, independent from the role of circulating estrogens, in regulating memory in aging females.SIGNIFICANCE STATEMENT Declines in ovarian hormones following menopause coincide with increased risk of cognitive decline. Because of potential health risks, current recommendations are that menopausal estrogen therapy be limited to a few years. Long-term consequences for the brain and memory of this short-term midlife estrogen therapy are unclear. Here, in a rodent model of menopause, we determined mechanisms by which short-term midlife estrogen exposure can enhance hippocampal function and memory with cognitive benefits and molecular changes enduring long after termination of estrogen exposure. Our model indicates long-lasting benefits of maintaining hippocampal estrogen receptor function in the absence of ongoing estrogen exposure and suggests potential strategies for combating age-related cognitive decline.

ABSTRACT

Melanoma in humans and dogs is considered highly immunogenic; however, the function of tumor-infiltrating lymphocytes (TILs) is often suppressed in the tumor microenvironment. In humans, current immunotherapies target checkpoint molecules (such as PD-L1, expressed by tumor cells), inhibiting their suppressive effect over TILs. The role of PD-L2, an alternative PD-1 ligand also overexpressed in malignant tumors and in patients with anti-PD-L1 resistance, remains poorly understood. In the current study, we evaluated the expression of checkpoint molecule mRNAs in canine melanoma and TILs. Analysis of checkpoint molecule gene expression was performed by RT-qPCR (real-time quantitative polymerase chain reaction) using total RNA isolated from formalin-fixed and paraffin-embedded melanomas (n = 22) and melanocytomas (n = 9) from the Virginia Tech Animal Laboratory Services archives. Analysis of checkpoint molecule expression revealed significantly higher levels of PDCD1 (PD-1) and CD274 (PD-L1) mRNAs and an upward trend in PDCD1LG2 (PD-L2) mRNA in melanomas relative to melanocytomas. Immunohistochemistry revealed markedly increased numbers of CD3+ T cells in the highest PD-1-expressing subgroup of melanomas compared to the lowest PD-1 expressors, whereas densities of IBA1+ cells (macrophages) were similar in both groups. CD79a+ cell numbers were low for both groups. As in human melanoma, overexpression of the PD-1/PD-L1/PD-L2 axis is a common feature of canine melanoma. High expression of PD-1 and PD-L1 correlates with increased numbers of CD3+ cells. Additionally, the high level of IBA1+ cells in melanomas with low PD-1 expression and low CD3+ cells levels suggest that the expression of checkpoint molecules is modulated by interactions between T cells and cancer cells rather than histiocytes.

ABSTRACT

BACKGROUND: Community health workers, known as Village Health Teams (VHTs) in Uganda, play a central role in increasing access to community-based health services. The objective of this research is to explore tensions that may emerge as VHTs navigate multiple roles as community members and care providers particularly when providing sensitive reproductive health and HIV care. METHODS: Twenty-five VHTs from a rural clinic in Uganda completed semi-structured interviews focused on experiences providing services. Interview questions focused on challenges VHTs face providing services and strategies for improving quality care. After translation from Luganda and transcription, interviews were analyzed using content analysis to identify emergent themes. RESULTS: Most VHTs were female (n = 16). The average age was 46, and average length of VHT work, 11 years. Analyses revealed that all VHTs capitalized upon the duality of their position, shifting roles depending upon context. Three themes emerged around VHTs' perceptions of their roles: community insiders, professional outsiders, and intermediaries. A caregiver "insider" role facilitated rapport and discussion of sensitive issues. As community members, VHTs leveraged existing community structures to educate clients in familiar settings such as "drinking places". However, this role posed challenges as some VHTs felt compelled to share their own resources including food and transport money. Occupying a professional outsider role offered VHTs respect. Their specialized knowledge gave them authority to counsel others on effective forms of family planning. However, some VHTs faced opposition, suspicions about their motives, and violence in this role. In balancing these two roles, the VHTs adopted a third as intermediaries, connecting the community to services in the formalized health care system. Participants suggested that additional training, ongoing supervision, and the opportunity to collaborate with other VHTs would help them better navigate their different roles and, ultimately, improve the quality of service. CONCLUSIONS: As countries scale up family planning and HIV services using VHTs, supportive supervision and ethical dilemma training are recommended so VHTs are prepared for the challenges of assuming multiple roles within communities.

ABSTRACT

Copines make up a family of calcium-dependent, phospholipid-binding proteins found in numerous eukaryotic organisms. Copine proteins consist of two C2 domains at the N-terminus followed by an A domain similar to the von Willebrand A domain found in integrins. We are studying copine protein function in the model organism, Dictyostelium discoideum, which has six copine genes, cpnA-cpnF. Previous research showed that cells lacking the cpnA gene exhibited a cytokinesis defect, a contractile vacuole defect, and developmental defects. To provide insight into the role of CpnA in these cellular processes, we used column chromatography and immunoprecipitation to isolate proteins that bind to CpnA. These proteins were identified by mass spectrometry. One of the proteins identified was actin. Purified CpnA was shown to bind to actin filaments in a calcium-dependent manner in vitro. cpnA- cells exhibited defects in three actin-based processes: chemotaxis, cell polarity, and adhesion. These results suggest that CpnA plays a role in chemotaxis and adhesion and may do so by interacting with actin filaments.

ABSTRACT

OBJECTIVE: Millions of women are interacting with Fifty Shades of Grey-a best-selling novel and film. Yet, to date, no social science study has been undertaken to examine women's perceptions of the Fifty Shades relationship narrative in its film adaptation-what they deem appealing, what they deem unappealing, and what they would welcome or resist in their own relationship. In the present study, we used focus groups to examine women's perceptions of the relationship patterns in the Fifty Shades of Grey film. METHODS: Focus groups were conducted with 35 young adult women (randomly sampled from the registrar's office of a large Midwestern university) immediately after watching the Fifty Shades film with the study team at a local theater within two days of the film's release. Seven semistructured questions concentrating on reactions to the relationship patterns between Christian Grey and Anastasia Steele depicted in the Fifty Shades film were asked, including general reactions, appealing and unappealing characteristics, romantic and dangerous elements, and aspects that participants would tolerate (or not tolerate) in their own relationships. RESULTS: While participants assessed parts of the relationship between Christian and Anastasia as exciting and romantic, they consistently indicated an unappealing lack of health in the relationship. Participants expressed grave concerns over Christian's stalking, controlling, manipulative, and emotionally abusive behavior, anger in sexual interactions, and neglect of Anastasia's needs. At the same time, they sympathized with and rationalized Christian's behaviors as a function of his personality, needs, and abilities. A small contingent implicated Anastasia in the unhealthy relationship process, whereas a broader majority of participants highlighted the challenges with trying to "speak up" in an unhealthy relationship like Christian and Anastasia's. When asked where participants would draw the line in their own relationship, participants indicated they would welcome the adventure and gifts, but would not tolerate being controlled and stalked, having their needs neglected, and having a partner who expressed anger in sexual interactions. CONCLUSIONS: Our findings point to the value of using popular culture, including the Fifty Shades narrative, to actively engage young women in productive conversation about characteristics of relationship health and un-health. Similar approaches could be used to engage young women in safe, relatable conversations about healthy and unhealthy relationships, including the warning signs of abuse. As a broader impact, our study contributes to an understanding of how young women interact with and make sense of relationships depicted in popular culture.

ABSTRACT

AIMS: To assess the effectiveness for Scotland's National Naloxone Programme (NNP) by comparison between 2006-10 (before) and 2011-13 (after NNP started in January 2011) and to assess cost-effectiveness. DESIGN: This was a pre-post evaluation of a national policy. Cost-effectiveness was assessed by prescription costs against life-years gained per opioid-related death (ORD) averted. SETTING: Scotland, in community settings and all prisons. INTERVENTION: Brief training and standardized naloxone supply became available to individuals at risk of opioid overdose. MEASUREMENTS: ORDs as identified by National Records of Scotland. Look-back determined the proportion of ORDs who, in the 4 weeks before ORD, had been (i) released from prison (primary outcome) and (ii) released from prison or discharged from hospital (secondary). We report 95% confidence intervals for effectiveness in reducing the primary (and secondary) outcome in 2011-13 versus 2006-10. Prescription costs were assessed against 1 or 10 life-years gained per averted ORD. FINDINGS: In 2006-10, 9.8% of ORDs (193 of 1970) were in people released from prison within 4 weeks of death, whereas only 6.3% of ORDs in 2011-13 followed prison release (76 of 1212, P < 0.001; this represented a difference of 3.5% [95% confidence interval (CI) = 1.6-5.4%)]. This reduction in the proportion of prison release ORDs translates into 42 fewer prison release ORDs (95% CI = 19-65) during 2011-13, when 12,000 naloxone kits were issued at current prescription cost of £225,000. Scotland's secondary outcome reduced from 19.0 to 14.9%, a difference of 4.1% (95% CI = 1.4-6.7%). CONCLUSIONS: Scotland's National Naloxone Programme, which started in 2011, was associated with a 36% reduction in the proportion of opioid-related deaths that occurred in the 4 weeks following release from prison.
