People, planet and consumption : how young New Zealanders are responding to their awareness of consumption and ecological concerns
Driven by consumerism, resource depletion directly impacts ecological degradation and contributes to planetary environmental destruction. This study explores how young New Zealanders develop an awareness of the effects of consumption and respond to related ecological concerns. At the time of this study the 17 young people who self-identified as Aotearoa New Zealand citizens were aged between 22–29 years. They were recruited through an online survey and participated in one-to-one interviews and a focus group. Using a modified grounded theory approach to elicit and examine their narratives, the research sought to identify key drivers that shaped these young people’s awareness of ecological degradation and their actions to conserve planetary resources. Implications drawn from this study are relevant for policymakers, educators and parents to understand the critical influences and actions imperative for developing future generations of ecological citizens. Changing dominant economic, political and social systems to develop individuals who will hold post-materialistic values and share ecological worldviews will not be easy, as this will require dynamic change to parenting approaches and other dominant models, including education. Structural changes initiated with a clear vision of what is needed and shared by trusted leaders across all levels of society, rather than just mandatory legislation changes, could help shift citizens towards more sustainable practices. Parents taking their children into the outdoors and exposing them to free-ranging exploration of nature develops long-lasting connections and an awareness of the environment. Introducing a new education paradigm, as argued by advocates of Education for Sustainable Development that places sustainability as the central core in thinking, teaching and learning. An education model that promotes a communal approach to teaching ecological citizenship, where social agency rather than individual agency is championed to prevent young people feeling overwhelmed with the complexity of what they are facing in light of environmental and social challenges. These insights will be useful to encourage and support future generations thinking and actions in more ecological ways as they begin to shoulder the burden and challenges associated with anthropogenic environmental change
A retrospective comparison of waterbirth outcomes in two United States hospital settings
BackgroundWater immersion during labor is an effective comfort measure; however, outcomes for waterbirth in the hospital setting have not been well documented. Our objective was to report the outcomes from two nurse‐midwifery services that provide waterbirth within a tertiary care hospital setting in the United States.MethodsThis study is a retrospective, observational, matched comparison design. Data were collected from two large midwifery practices in tertiary care centers using information recorded at the time of birth for quality assurance purposes. Land birth cases were excluded if events would have precluded them from waterbirth (epidural, meconium stained fluid, chorioamnionitis, estimated gestational age 40). Neonatal outcomes included Apgar score and admission to the neonatal intensive care unit. Maternal outcomes included perineal lacerations and postpartum hemorrhage.ResultsA total of 397 waterbirths and 2025 land births were included in the analysis. There were no differences in outcomes between waterbirth and land birth for Apgar scores or neonatal intensive care admissions (1.8% vs 2.5%). Women in the waterbirth group were less likely to sustain a first‐ or second‐degree laceration. Postpartum hemorrhage rates were similar for both groups. Similar results were obtained using a land birth subset matched on insurance, hospital location, and parity using propensity scores.DiscussionIn this study, waterbirth was not associated with increased risk to neonates, extensive perineal lacerations, or postpartum hemorrhage. Fewer women in the waterbirth group sustained first‐ or second‐degree lacerations requiring sutures.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154290/1/birt12473.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154290/2/birt12473_am.pd
“Save Our History!” Collaborating to Preserve the Past at UMass Boston
Sparked by the 50th anniversary of the founding of the University of Massachusetts Boston in June 1964, University Archives and Special Collections (UASC) staff in the Joseph P. Healey Library collaborated with departments across campus to carry out a wide range of initiatives, all focused on locating, accessioning, preserving, and sharing the physical evidence of the university’s history. This poster outlines the various collecting activities, outreach methods, digitization projects, and dogged detective work that resulted in the addition of more than 2,500 linear feet of unique historic materials to the University Archives, as well as a number of well-received public events and exhibitions

Ethanol reversal of tolerance to the respiratory depressant effects of morphine
Opioids are the most common drugs associated with unintentional drug overdose. Death results from respiratory depression. Prolonged use of opioids results in the development of tolerance but the degree of tolerance is thought to vary between different effects of the drugs. Many opioid addicts regularly consume alcohol (ethanol), and post-mortem analyses of opioid overdose deaths have revealed an inverse correlation between blood morphine and ethanol levels. In the present study, we determined whether ethanol reduced tolerance to the respiratory depressant effects of opioids. Mice were treated with opioids (morphine, methadone, or buprenorphine) for up to 6 days. Respiration was measured in freely moving animals breathing 5% CO(2) in air in plethysmograph chambers. Antinociception (analgesia) was measured as the latency to remove the tail from a thermal stimulus. Opioid tolerance was assessed by measuring the response to a challenge dose of morphine (10 mg/kg i.p.). Tolerance developed to the respiratory depressant effect of morphine but at a slower rate than tolerance to its antinociceptive effect. A low dose of ethanol (0.3 mg/kg) alone did not depress respiration but in prolonged morphine-treated animals respiratory depression was observed when ethanol was co-administered with the morphine challenge. Ethanol did not alter the brain levels of morphine. In contrast, in methadone- or buprenorphine-treated animals no respiratory depression was observed when ethanol was co-administered along with the morphine challenge. As heroin is converted to morphine in man, selective reversal of morphine tolerance by ethanol may be a contributory factor in heroin overdose deaths
Single-cell RNA-seq reveals transcriptomic heterogeneity mediated by host-pathogen dynamics in lymphoblastoid cell lines
Lymphoblastoid cell lines (LCLs) are generated by transforming primary B cells with Epstein-Barr virus (EBV) and are used extensively as model systems in viral oncology, immunology, and human genetics research. In this study, we characterized single-cell transcriptomic profiles of five LCLs and present a simple discrete-time simulation to explore the influence of stochasticity on LCL clonal evolution. Single-cell RNA sequencing (scRNA-seq) revealed substantial phenotypic heterogeneity within and across LCLs with respect to immunoglobulin isotype; virus-modulated host pathways involved in survival, activation, and differentiation; viral replication state; and oxidative stress. This heterogeneity is likely attributable to intrinsic variance in primary B cells and host-pathogen dynamics. Stochastic simulations demonstrate that initial primary cell heterogeneity, random sampling, time in culture, and even mild differences in phenotype-specific fitness can contribute substantially to dynamic diversity in populations of nominally clonal cells

Closely related Lak megaphages replicate in the microbiomes of diverse animals.
Lak phages with alternatively coded ∼540 kbp genomes were recently reported to replicate in Prevotella in microbiomes of humans that consume a non-Western diet, baboons, and pigs. Here, we explore Lak phage diversity and broader distribution using diagnostic polymerase chain reaction and genome-resolved metagenomics. Lak phages were detected in 13 animal types, including reptiles, and are particularly prevalent in pigs. Tracking Lak through the pig gastrointestinal tract revealed significant enrichment in the hindgut compared to the foregut. We reconstructed 34 new Lak genomes, including six curated complete genomes, all of which are alternatively coded. An anomalously large (∼660 kbp) complete genome reconstructed for the most deeply branched Lak from a horse microbiome is also alternatively coded. From the Lak genomes, we identified proteins associated with specific animal species; notably, most have no functional predictions. The presence of closely related Lak phages in diverse animals indicates facile distribution coupled to host-specific adaptation
Transcriptomic analysis of cutaneous squamous cell carcinoma reveals a multi-gene prognostic signature associated with metastasis
Background: Metastasis of cutaneous squamous cell carcinoma (cSCC) is uncommon. Current staging methods are reported to have sub-optimal performances in metastasis prediction. Accurate identification of patients with tumours at high risk of metastasis would have a significant impact on management.Objective: To develop a robust and validated gene expression profile (GEP) signature for predicting primary cSCC metastatic risk using an unbiased whole transcriptome discovery-driven approach.Methods: Archival formalin-fixed paraffin-embedded primary cSCC with perilesional normal tissue from 237 immunocompetent patients (151 non-metastasising and 86 metastasising) were collected retrospectively from four centres. TempO-seq was used to probe the whole transcriptome and machine learning algorithms were applied to derive predictive signatures, with a 3:1 split for training and testing datasets.Results: A 20-gene prognostic model was developed and validated, with an accuracy of 86.0%, sensitivity of 85.7%, specificity of 86.1%, and positive predictive value of 78.3% in the testing set, providing more stable, accurate prediction than pathological staging systems. A linear predictor was also developed, significantly correlating with metastatic risk.Limitations: This was a retrospective 4-centre study and larger prospective multicentre studies are now required.Conclusion: The 20-gene signature prediction is accurate, with the potential to be incorporated into clinical workflows for cSCC
Influence of family and friend smoking on intentions to smoke and smoking-related attitudes and refusal self-efficacy among 9-10 year old children from deprived neighbourhoods: a cross-sectional study.
BACKGROUND: Smoking often starts in early adolescence and addiction can occur rapidly. For effective smoking prevention there is a need to identify at risk groups of preadolescent children and whether gender-specific intervention components are necessary. This study aimed to examine associations between mother, father, sibling and friend smoking and cognitive vulnerability to smoking among preadolescent children living in deprived neighbourhoods. METHODS: Cross-sectional data was collected from 9-10 year old children (n =1143; 50.7% girls; 85.6% White British) from 43 primary schools in Merseyside, England. Children completed a questionnaire that assessed their smoking-related behaviour, intentions, attitudes, and refusal self-efficacy, as well as parent, sibling and friend smoking. Data for boys and girls were analysed separately using multilevel linear and logistic regression models, adjusting for individual cognitions and school and deprivation level. RESULTS: Compared to girls, boys had lower non-smoking intentions (P = 0.02), refusal self-efficacy (P = 0.04) and were less likely to agree that smoking is 'definitely' bad for health (P < 0.01). Friend smoking was negatively associated with non-smoking intentions in girls (P < 0.01) and boys (P < 0.01), and with refusal self-efficacy in girls (P < 0.01). Sibling smoking was negatively associated with non-smoking intentions in girls (P < 0.01) but a positive association was found in boys (P = 0.02). Boys who had a smoking friend were less likely to 'definitely' believe that the smoke from other people's cigarettes is harmful (OR 0.57, 95% CI: 0.35 to 0.91, P = 0.02). Further, boys with a smoking friend (OR 0.38, 95% CI: 0.21 to 0.69, P < 0.01) or a smoking sibling (OR 0.45, 95% CI: 0.21 to 0.98) were less likely to 'definitely' believe that smoking is bad for health. CONCLUSION: This study indicates that sibling and friend smoking may represent important influences on 9-10 year old children's cognitive vulnerability toward smoking. Whilst some differential findings by gender were observed, these may not be sufficient to warrant separate prevention interventions. However, further research is needed
