Literate Change Agents Working in Oral Communities: Navigating Paradigm Shifts

This research documents the experience of 12 local leaders implementing an oral curriculum over 13 months in Karnataka, India. These leaders were Change Agents interested in influencing a community with new information. They created audio materials referred to as “content” in their group’s mother tongue: In a Kannada-Telegu mix for the Madiga group (a Scheduled Caste); in Vaagri Booli for the Hakkipikki group (a Scheduled Tribe); and in Kannada for the Kannadiga group. The first two languages are unwritten. The Kannada language is the official language of Karnataka state. The oral curriculum followed the Spoken Worldwide® model. Each team of local leaders designed their content by combining a topic, a local proverb, and an informative resource in story form. Next, the individual leaders facilitated discussion groups in their community centered on the content. Eighteen men were interviewed; this included six community discussion group members. The Connected Learning Framework was the conceptual lens for this research. It consists of four constructs—relationship, relevance, oral modes of communication, and mutual respect. Relationships played a primary role because the learners preferred to work with individuals they knew, or with individuals who were approved by the community’s leaders. Content that centered on what was relevant to community members was well-received by the listeners. The leaders used modes of communication that were familiar to community members by presenting content in the mother tongue and including local proverbs. By facilitating discussion after presenting the content, the leaders demonstrated mutual respect ensuring a multidirectional flow of information. This informed how the leaders created subsequent content. This research found that introducing new ideas, specifically Christian Scripture as a source of wisdom, was received positively by almost all audiences. In addition, the Team Leaders who had more experience using oral modes of communication, specifically telling Bible stories, and facilitating discussion were more consistent in implementing the Spoken process and principles and modeled the process during the content creation sessions with their Local Leaders or in presenting the content in their Leader’s gatherings. These leaders who had more experience with Connect Learning strategies were able to navigate further in the oral learning paradigm

A novel inhibitor of p75-neurotrophin receptor improves functional outcomes in two models of traumatic brain injury.

The p75 neurotrophin receptor is important in multiple physiological actions including neuronal survival and neurite outgrowth during development, and after central nervous system injury. We have discovered a novel piperazine-derived compound, EVT901, which interferes with p75 neurotrophin receptor oligomerization through direct interaction with the first cysteine-rich domain of the extracellular region. Using ligand binding assays with cysteine-rich domains-fused p75 neurotrophin receptor, we confirmed that EVT901 interferes with oligomerization of full-length p75 neurotrophin receptor in a dose-dependent manner. Here we report that EVT901 reduces binding of pro-nerve growth factor to p75 neurotrophin receptor, blocks pro-nerve growth factor induced apoptosis in cells expressing p75 neurotrophin receptor, and enhances neurite outgrowth in vitro Furthermore, we demonstrate that EVT901 abrogates p75 neurotrophin receptor signalling by other ligands, such as prion peptide and amyloid-β. To test the efficacy of EVT901 in vivo, we evaluated the outcome in two models of traumatic brain injury. We generated controlled cortical impacts in adult rats. Using unbiased stereological analysis, we found that EVT901 delivered intravenously daily for 1 week after injury, reduced lesion size, protected cortical neurons and oligodendrocytes, and had a positive effect on neurological function. After lateral fluid percussion injury in adult rats, oral treatment with EVT901 reduced neuronal death in the hippocampus and thalamus, reduced long-term cognitive deficits, and reduced the occurrence of post-traumatic seizure activity. Together, these studies provide a new reagent for altering p75 neurotrophin receptor actions after injury and suggest that EVT901 may be useful in treatment of central nervous system trauma and other neurological disorders where p75 neurotrophin receptor signalling is affected

Transplantation of Kidneys from Donors with Acute Renal Failure Five-Year Results from Double Center Experience

Background: Transplantation of kidneys from deceased donors with acute renal failure (ARF) has been described and represents an underutilized source of renal grafts. We reviewed retrospectively our double center experience with transplantation of ARF donor kidneys. Methods: Between January 2009 and June 2014, we performed a total of 397 kidney transplants at the two hospitals. Of which, 65 came from donors with ARF. The outcome was compared with 62 expanded criteria donor kidneys and 270 standard criteria donor kidneys. ARF was defined as donor terminal creatinine higher than 2. All kidneys from ARF donors had acceptable biopsies and were pumped. The immunosuppression was similar in all three groups (Thymoglobulin for induction and Prograf, Cellcept and steroids for maintenance). The outcome measurements included recipient serum creatinine, patient and graft survival at 6 months, 1 year and 3 years. We also reviewed the delayed graft function (DGF) rates and cold ischemic time in all groups. Results: Mean donor creatinine was 3.84±1.3. The 6 month, 1 and 3 year patient survival rates were 98.5%, 96.8% and 92.0% in ARF group, 98.1%, 97.0% and 93.4% SCD group and 98.4%, 93.2% and 77.7% in ECD group. The 6 month, 1 and 3 year death censored graft survival was 96.9%, 96.9%, 96.9% in ARF group, 97.7, 96.5, 91.8 in SCD group and 95.1%, 93.2%, 90.1% in ECD group. The mean 6mo, 1 year and 3 year recipient creatinine was 1.49, 1.46 and 1.51 in ARF group, 1.61, 1.72 and 1.77 in SCD group and 1.91, 1.92 and 2.15 in ECD group, respectively. ARF kidneys are noted to be associated with more DGF (58.5% in ARF group VS 41.5% in non ARF group), longer cold ischemic time (857.79 min in ARF group vs 589.32 min in non ARF group) and younger donor age (32.25 years in ARF group vs 40.65 years in non ARF group). Conclusion: Elevated terminal donor creatinine is not a risk factor for graft loss after deceased donor kidney transplantation. Although there is increased risk of DGF and longer cold ischemic time, transplantation of ARF kidneys provides comparable short and long term graft function and patient survival compared to kidneys from non ARF donors

What is the potential for plural ownership to support a more inclusive economy? A systematic review protocol

Abstract: Background: The world is facing an unprecedented systemic shock to population health, the economy and society due to the devastating impact of the COVID-19 pandemic. As with most economic shocks, this is expected to disproportionately impact vulnerable groups in society such as those in poverty and those in precarious employment as well as marginalised groups such as women, the elderly, Black, Asian and Minority Ethnic (BAME) groups and those with health conditions. The current literature is rich in normative recommendations on plural ownership as a key building block of an inclusive economy rooted in communities and their needs. There is, however, a need for a rigorous synthesis of the available evidence on what impact (if any) plural ownership may potentially have on the inclusivity of the economy. This review seeks to synthesise and compare the available evidence across the three economic sectors (private, public and third). Methods: We will search eight bibliographic databases (Sociological abstracts, EBSCO Econlit, OVID Embase, OVID Medline, Applied Social Sciences Index and Abstracts (ASSIA), ProQuest Public Health, Web of Science, Research Papers in Economics (Repec) – EconPapers) from the earliest data available in each database until January 2021. Grey literature will be identified from Google (advanced), Google Scholar and 37 organisational websites identified as relevant to the research question. We will include comparative studies of plural ownership from high-income countries that report outcomes on access to opportunities, distribution of benefits, poverty, and discrimination. A bespoke search strategy will be used for each website to account for the heterogeneity in content and search capabilities and will be fully documented. A standardised data extraction template based on the Population-Intervention-Context-Outcome (PICO) template will be developed. We will assess the strength of evidence for different forms of economic ownership identified in relation to the impact of each on the four economic outcomes of interest, paying particular attention to the role of wider contextual factors as they emerge through the evidence. Discussion: The findings of this review are intended to inform policymaking at local, national and international level that prioritises and supports the development of different economic and business models.

A novel approach to investigate tissue-specific trinucleotide repeat instability

Abstract Background In Huntington's disease (HD), an expanded CAG repeat produces characteristic striatal neurodegeneration. Interestingly, the HD CAG repeat, whose length determines age at onset, undergoes tissue-specific somatic instability, predominant in the striatum, suggesting that tissue-specific CAG length changes could modify the disease process. Therefore, understanding the mechanisms underlying the tissue specificity of somatic instability may provide novel routes to therapies. However progress in this area has been hampered by the lack of sensitive high-throughput instability quantification methods and global approaches to identify the underlying factors. Results Here we describe a novel approach to gain insight into the factors responsible for the tissue specificity of somatic instability. Using accurate genetic knock-in mouse models of HD, we developed a reliable, high-throughput method to quantify tissue HD CAG repeat instability and integrated this with genome-wide bioinformatic approaches. Using tissue instability quantified in 16 tissues as a phenotype and tissue microarray gene expression as a predictor, we built a mathematical model and identified a gene expression signature that accurately predicted tissue instability. Using the predictive ability of this signature we found that somatic instability was not a consequence of pathogenesis. In support of this, genetic crosses with models of accelerated neuropathology failed to induce somatic instability. In addition, we searched for genes and pathways that correlated with tissue instability. We found that expression levels of DNA repair genes did not explain the tissue specificity of somatic instability. Instead, our data implicate other pathways, particularly cell cycle, metabolism and neurotransmitter pathways, acting in combination to generate tissue-specific patterns of instability. Conclusion Our study clearly demonstrates that multiple tissue factors reflect the level of somatic instability in different tissues. In addition, our quantitative, genome-wide approach is readily applicable to high-throughput assays and opens the door to widespread applications with the potential to accelerate the discovery of drugs that alter tissue instability

Perceptions of the appropriate response to norm violation in 57 societies

An Author Correction to this article: DOI: 10.1038/s41467-021-22955-x.Norm enforcement may be important for resolving conflicts and promoting cooperation. However, little is known about how preferred responses to norm violations vary across cultures and across domains. In a preregistered study of 57 countries (using convenience samples of 22,863 students and non-students), we measured perceptions of the appropriateness of various responses to a violation of a cooperative norm and to atypical social behaviors. Our findings highlight both cultural universals and cultural variation. We find a universal negative relation between appropriateness ratings of norm violations and appropriateness ratings of responses in the form of confrontation, social ostracism and gossip. Moreover, we find the country variation in the appropriateness of sanctions to be consistent across different norm violations but not across different sanctions. Specifically, in those countries where use of physical confrontation and social ostracism is rated as less appropriate, gossip is rated as more appropriate.Peer reviewe

Atrasentan and renal events in patients with type 2 diabetes and chronic kidney disease (SONAR): a double-blind, randomised, placebo-controlled trial

Background: Short-term treatment for people with type 2 diabetes using a low dose of the selective endothelin A receptor antagonist atrasentan reduces albuminuria without causing significant sodium retention. We report the long-term effects of treatment with atrasentan on major renal outcomes. Methods: We did this double-blind, randomised, placebo-controlled trial at 689 sites in 41 countries. We enrolled adults aged 18–85 years with type 2 diabetes, estimated glomerular filtration rate (eGFR)25–75 mL/min per 1·73 m 2 of body surface area, and a urine albumin-to-creatinine ratio (UACR)of 300–5000 mg/g who had received maximum labelled or tolerated renin–angiotensin system inhibition for at least 4 weeks. Participants were given atrasentan 0·75 mg orally daily during an enrichment period before random group assignment. Those with a UACR decrease of at least 30% with no substantial fluid retention during the enrichment period (responders)were included in the double-blind treatment period. Responders were randomly assigned to receive either atrasentan 0·75 mg orally daily or placebo. All patients and investigators were masked to treatment assignment. The primary endpoint was a composite of doubling of serum creatinine (sustained for ≥30 days)or end-stage kidney disease (eGFR <15 mL/min per 1·73 m 2 sustained for ≥90 days, chronic dialysis for ≥90 days, kidney transplantation, or death from kidney failure)in the intention-to-treat population of all responders. Safety was assessed in all patients who received at least one dose of their assigned study treatment. The study is registered with ClinicalTrials.gov, number NCT01858532. Findings: Between May 17, 2013, and July 13, 2017, 11 087 patients were screened; 5117 entered the enrichment period, and 4711 completed the enrichment period. Of these, 2648 patients were responders and were randomly assigned to the atrasentan group (n=1325)or placebo group (n=1323). Median follow-up was 2·2 years (IQR 1·4–2·9). 79 (6·0%)of 1325 patients in the atrasentan group and 105 (7·9%)of 1323 in the placebo group had a primary composite renal endpoint event (hazard ratio [HR]0·65 [95% CI 0·49–0·88]; p=0·0047). Fluid retention and anaemia adverse events, which have been previously attributed to endothelin receptor antagonists, were more frequent in the atrasentan group than in the placebo group. Hospital admission for heart failure occurred in 47 (3·5%)of 1325 patients in the atrasentan group and 34 (2·6%)of 1323 patients in the placebo group (HR 1·33 [95% CI 0·85–2·07]; p=0·208). 58 (4·4%)patients in the atrasentan group and 52 (3·9%)in the placebo group died (HR 1·09 [95% CI 0·75–1·59]; p=0·65). Interpretation: Atrasentan reduced the risk of renal events in patients with diabetes and chronic kidney disease who were selected to optimise efficacy and safety. These data support a potential role for selective endothelin receptor antagonists in protecting renal function in patients with type 2 diabetes at high risk of developing end-stage kidney disease.

Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies

When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions
