Visualizing the Influence of Social Networks on Recovery:A Mixed-Methods Social Identity Mapping Study with Recovering Adolescents

BackgroundSocial recovery capital (SRC) refers to resources and supports gained through relationships and is vital to adolescent addiction recovery. Much is known about how substance use relates to social networks, but little is known about how other dimensions of social networks influence recovery (e.g., network size/exposure, degree of conflict). MethodsThis mixed-methods study sampled 28 adolescents who received treatment for alcohol and other drug (AOD) use disorder (14-19 yrs.: 71% male; M=17.32 yrs., SD=1.33; White 82%): 20 were recovery high school (RHS) students. Adolescents completed a social identity map for addiction recovery (SIM-AR), survey, and interview. Qualitative data were content analyzed and the data from the SIM-AR were quantified. ResultsOn average, participants reported belonging to five having 5 distinct groups (Range, 2-9; SD=1.63; M=27.89 people, SD = 20.09) in their network. Of their social network connections, on average, 51% drank alcohol and 46% used other substances. Larger networks involved more conflict (r=0.57). Participants were more likely to spend more time with groups that had greater proportions of non-substance usinge members; these relationships were stronger for RHS than for non-RHS students. Qualitative analyses revealed that youth reported their recovery-oriented groups as supportive, yet some felt their substance-using friends also supported their recovery.DiscussionSIM-AR was a useful measurement tool, and, through qualitative interviews, we identified unique aspects of youth’s social networks important for further examination. Research with recovering youth should examine SRC-related elements within their networks including relationship quality, belonging, and conflict, in addition to the substance use behaviors of network members. <br/

Accompanying Survivors of Sexual Harm: A Toolkit for Churches

Accompanying Survivors of Sexual Harm is a trauma-informed resource that offers education and support of Christian clergy and lay leaders as they respond to sexual harm in their communities. It lays out plans for workshop-based sessions, which aim to educate clergy and lay leaders about • Understanding the nature of sexual harm and its prevalence in New Zealand society • Being alert to and responding in a pastorally sensitive manner to people within their community who have experienced/are experiencing sexual harm • Identifying and articulating some of the scriptural and theological foundations that work to justify/legitimise/enable sexual harm while silencing the voices of victims/survivors • Identifying and articulating some of the scriptural and theological foundations that work to challenge and resist sexual harm • Exploring how their church might work to create a safe space for victims/survivors of sexual harm. The toolkit will be of value to anyone in a church leadership position, including those training for Christian ministry and those who have extensive ministry/leadership experience. It is intentionally ecumenical in nature and does not require knowledge of any one denominational tradition. While some of the content relates specifically to the context of Aotearoa New Zealand, most of the material can be adapted and used further afield. There is space offered throughout the sessions for participants to discuss how issues pertaining to sexual harm relate to their own communities. Participants also have opportunities to consider how their own cultures, contexts, traditions, and languages will help shape their role of accompanying victims and survivors. The toolkit is free for anyone to download and use. If you have any queries about the use of the toolkit, please contact us at [email protected]. We hope this resource is a useful and meaningful tool for all those who accompany victims and survivors on their journey

Single cell analysis reveals human cytomegalovirus drives latently infected cells towards an anergic-like monocyte state

Human cytomegalovirus (HCMV) causes a lifelong infection through establishment of latency. Although reactivation from latency can cause life-threatening disease, our molecular understanding of HCMV latency is incomplete. Here we use single cell RNA-seq analysis to characterize latency in monocytes and hematopoietic stem and progenitor cells (HSPCs). In monocytes, we identify host cell surface markers that enable enrichment of latent cells harboring higher viral transcript levels, which can reactivate more efficiently, and are characterized by reduced intrinsic immune response that is important for viral gene expression. Significantly, in latent HSPCs, viral transcripts could be detected only in monocyte progenitors and were also associated with reduced immune-response. Overall, our work indicates that regardless of the developmental stage in which HCMV infects, HCMV drives hematopoietic cells towards a weaker immune-responsive monocyte state and that this anergic-like state is crucial for the virus ability to express its transcripts and to eventually reactivate

Whole-genome approach to assessing human cytomegalovirus dynamics in transplant patients undergoing antiviral therapy

Human cytomegalovirus (HCMV) is the most frequent cause of opportunistic viral infection following transplantation. Viral factors of potential clinical importance include the selection of mutants resistant to antiviral drugs and the occurrence of infections involving multiple HCMV strains. These factors are typically addressed by analyzing relevant HCMV genes by PCR and Sanger sequencing, which involves independent assays of limited sensitivity. To assess the dynamics of viral populations with high sensitivity, we applied high-throughput sequencing coupled with HCMV-adapted target enrichment to samples collected longitudinally from 11 transplant recipients (solid organ, n=9, and allogeneic hematopoietic stem cell, n=2). Only the latter presented multiple-strain infections. Four cases presented resistance mutations (n=6), two (A594V and L595S) at high (100%) and four (V715M, 32 V781I, A809V and T838A) at low (&lt;25%) frequency. One allogeneic hematopoietic stem cell transplant recipient presented up to four resistance mutations, each at low frequency. The use of high throughput sequencing to monitor mutations and strain composition in people at risk of HCMV disease is of potential value in helping clinicians implement the most appropriate therapy

Challenges in quantifying changes in the global water cycle

Human influences have likely already impacted the large-scale water cycle but natural variability and observational uncertainty are substantial. It is essential to maintain and improve observational capabilities to better characterize changes. Understanding observed changes to the global water cycle is key to predicting future climate changes and their impacts. While many datasets document crucial variables such as precipitation, ocean salinity, runoff, and humidity, most are uncertain for determining long-term changes. In situ networks provide long time-series over land but are sparse in many regions, particularly the tropics. Satellite and reanalysis datasets provide global coverage, but their long-term stability is lacking. However, comparisons of changes among related variables can give insights into the robustness of observed changes. For example, ocean salinity, interpreted with an understanding of ocean processes, can help cross-validate precipitation. Observational evidence for human influences on the water cycle is emerging, but uncertainties resulting from internal variability and observational errors are too large to determine whether the observed and simulated changes are consistent. Improvements to the in situ and satellite observing networks that monitor the changing water cycle are required, yet continued data coverage is threatened by funding reductions. Uncertainty both in the role of anthropogenic aerosols, and due to large climate variability presently limits confidence in attribution of observed changes

Tumor matrix stiffness promotes metastatic cancer cell interaction with the endothelium

Tumor progression alters the composition and physical properties of the extracellular matrix. Particularly, increased matrix stiffness has profound effects on tumor growth and metastasis. While endothelial cells are key players in cancer progression, the influence of tumor stiffness on the endothelium and the impact on metastasis is unknown. Through quantitative mass spectrometry, we find that the matricellular protein CCN1/CYR61 is highly regulated by stiffness in endothelial cells. We show that stiffness‐induced CCN1 activates β‐catenin nuclear translocation and signaling and that this contributes to upregulate N‐cadherin levels on the surface of the endothelium, in vitro. This facilitates N‐cadherin‐dependent cancer cell–endothelium interaction. Using intravital imaging, we show that knockout of Ccn1 in endothelial cells inhibits melanoma cancer cell binding to the blood vessels, a critical step in cancer cell transit through the vasculature to metastasize. Targeting stiffness‐induced changes in the vasculature, such as CCN1, is therefore a potential yet unappreciated mechanism to impair metastasis

Grey matter in shadow banking: international organizations and expert strategies in global financial governance

Who controls global policy debates on shadow banking regulation? We show how experts secured control over how issues in shadow banking regulation are treated by examining the policy recommendations of the Bank of International Settlements, the International Monetary Fund and the Financial Stability Board. The evidence suggests that IO experts embedded a bland reformism opposed to both strong and ‘light touch’ regulation at the core of the emerging regulatory regime. Technocrats reinforced each other's expertise, excluded some potential competitors (legal scholars), co-opted others (select Fed and elite academic economists), and deployed measurement, mandate, and status strategies to assert issue control. In the field of shadow banking regulation, academic economists’ influence came from their credibility as arbitrageurs between several professional fields rather than their intellectual output. The findings have important implications for how we study the relationship between IO technocrats and experts from other professional field

No father required? The welfare assessment in the Human Fertilisation and Embryology Act 2008

Of all the changes to the Human Fertilisation and Embryology Act 1990 that were introduced in 2008 by legislation of the same name, foremost to excite media attention and popular controversy was the amendment of the so-called welfare clause. This clause forms part of the licensing conditions which must be met by any clinic before offering those treatment services covered by the legislation. The 2008 Act deleted the statutory requirement that clinicians consider the need for a father of any potential child before offering a woman treatment, substituting for it a requirement that clinicians must henceforth consider the child’s need for “supportive parenting”. In this paper, we first briefly recall the history of the introduction of s 13(5) in the 1990 Act, before going on to track discussion of its amendment through the lengthy reform process that preceded the introduction of the 2008 Act. We then discuss the meaning of the phrase “supportive parenting” with reference to guidance regarding its interpretation offered by the Human Fertilisation and Embryology Authority. While the changes to s 13(5) have been represented as suggesting a major change in the law, we suggest that the reworded section does not represent a significant break from the previous law as it had been interpreted in practice. This raises the question of why it was that an amendment that is likely to make very little difference to clinical practice tended to excite such attention (and with such polarising force). To this end, we locate debates regarding s 13(5) within a broader context of popular anxieties regarding the use of reproductive technologies and, specifically, what they mean for the position of men within the family

Cancer-associated fibroblasts produce matrix-bound vesicles that influence endothelial cell function

Intercellular communication between different cell types in solid tumors contributes to tumor growth and metastatic dissemination. The secretome of cancer-associated fibroblasts (CAFs) plays major roles in these processes. Using human mammary CAFs, we showed that CAFs with a myofibroblast phenotype released extracellular vesicles that transferred proteins to endothelial cells (ECs) that affected their interaction with immune cells. Mass spectrometry–based proteomics identified proteins transferred from CAFs to ECs, which included plasma membrane receptors. Using THY1 as an example of a transferred plasma membrane–bound protein, we showed that CAF-derived proteins increased the adhesion of a monocyte cell line to ECs. CAFs produced high amounts of matrix-bound EVs, which were the primary vehicles of protein transfer. Hence, our work paves the way for future studies that investigate how CAF-derived matrix-bound EVs influence tumor pathology by regulating the function of neighboring cancer, stromal, and immune cells
