Conversations on âCommunity Lawyeringâ: The Newest (Oldest) Wave in Clinical Legal Education
In this Essay, we will explore the pedagogical and professional challenges and rewards of community lawyering and clinical legal education. The authors are clinical law faculty who self-identify as community lawyers and teachers of community lawyering clinics. We have gathered in recent years with a larger group of similarly engaged colleagues to discuss what we mean by community lawyering, how we teach it, and how we practice it. This Essay seeks to capture some of those conversations, crystallize some of the ideas that have arisen out of the discussions, and examine the implications of these ruminations for future directions in clinical legal education
Mitochondrial uncoupling links lipid catabolism to Akt inhibition and resistance to tumorigenesis
To support growth, tumour cells reprogramme their metabolism to simultaneously upregulate macromolecular biosynthesis while maintaining energy production. Uncoupling proteins (UCPs) oppose this phenotype by inducing futile mitochondrial respiration that is uncoupled from ATP synthesis, resulting in nutrient wasting. Here using a UCP3 transgene targeted to the basal epidermis, we show that forced mitochondrial uncoupling inhibits skin carcinogenesis by blocking Akt activation. Similarly, Akt activation is markedly inhibited in UCP3 overexpressing primary human keratinocytes. Mechanistic studies reveal that uncoupling increases fatty acid oxidation and membrane phospholipid catabolism, and impairs recruitment of Akt to the plasma membrane. Overexpression of Akt overcomes metabolic regulation by UCP3, rescuing carcinogenesis. These findings demonstrate that mitochondrial uncoupling is an effective strategy to limit proliferation and tumorigenesis through inhibition of Akt, and illuminate a novel mechanism of crosstalk between mitochondrial metabolism and growth signalling

Missing steps in a staircase: a qualitative study of the perspectives of key stakeholders on the use of adaptive designs in confirmatory trials
Background
Despite the promising benefits of adaptive designs (ADs), their routine use, especially in confirmatory trials, is lagging behind the prominence given to them in the statistical literature. Much of the previous research to understand barriers and potential facilitators to the use of ADs has been driven from a pharmaceutical drug development perspective, with little focus on trials in the public sector. In this paper, we explore key stakeholdersâ experiences, perceptions and views on barriers and facilitators to the use of ADs in publicly funded confirmatory trials.
Methods
Semi-structured, in-depth interviews of key stakeholders in clinical trials research (CTU directors, funding board and panel members, statisticians, regulators, chief investigators, data monitoring committee members and health economists) were conducted through telephone or face-to-face sessions, predominantly in the UK. We purposively selected participants sequentially to optimise maximum variation in views and experiences. We employed the framework approach to analyse the qualitative data.
Results
We interviewed 27 participants. We found some of the perceived barriers to be: lack of knowledge and experience coupled with paucity of case studies, lack of applied training, degree of reluctance to use ADs, lack of bridge funding and time to support design work, lack of statistical expertise, some anxiety about the impact of early trial stopping on researchersâ employment contracts, lack of understanding of acceptable scope of ADs and when ADs are appropriate, and statistical and practical complexities. Reluctance to use ADs seemed to be influenced by: therapeutic area, unfamiliarity, concerns about their robustness in decision-making and acceptability of findings to change practice, perceived complexities and proposed type of AD, among others.
Conclusions
There are still considerable multifaceted, individual and organisational obstacles to be addressed to improve uptake, and successful implementation of ADs when appropriate. Nevertheless, inferred positive change in attitudes and receptiveness towards the appropriate use of ADs by public funders are supportive and are a stepping stone for the future utilisation of ADs by researchers
The problem of constitutional legitimation: what the debate on electoral quotas tells us about the legitimacy of decision-making rules in constitutional choice
Proponents of electoral quotas have a âdependent interpretationâ of democracy, i.e. they have formed an opinion on which decision-making rules are fair on the basis of their prior approval of the outcomes these rules are likely to generate. The article argues that this position causes an irresolvable problem for constitutional processes that seek to legitimately enact institutional change. While constitutional revision governed by formal equality allows the introduction of electoral quotas, this avenue is normatively untenable for proponents of affirmative action if they are consistent with their claim that formal equality reproduces biases and power asymmetries at all levels of decision-making. Their critique raises a fundamental challenge to the constitutional revision rule itself as equally unfair. Without consensus on the decision-making process by which new post-constitutional rules can be legitimately enacted, procedural fairness becomes an issue impossible to resolve at the stage of constitutional choice. This problem of legitimation affects all instances of constitutional choice in which there are opposing views not only about the desired outcome of the process but also about the decision-making rules that govern constitutional choice

Trends in Imaging Findings, Interventions, and Outcomes Among Children With Isolated Head Trauma
ObjectiveThe aim was to analyze the impact of decreased head computed tomography (CT) imaging on detection of abnormalities and outcomes for children with isolated head trauma.MethodsThe study involves a multicenter retrospective cohort of patients younger than 19 years presenting for isolated head trauma to emergency departments in the Pediatric Health Information System database from 2003 to 2015. Patients directly admitted or transferred to another facility and those with a discharge diagnosis code for child maltreatment were excluded. Outcomes were ascertained from administrative and billing data. Trends were tested using mixed effects logistic regression, accounting for clustering within hospitals and adjusted for age, sex, insurance type, race, presence of a complex chronic condition, and hospital-level case mix index.ResultsBetween 2003 and 2015, 306,041 children presented for isolated head trauma. The proportion of children receiving head CT imaging was increasing until 2008, peaking at just under 40%, before declining to 25% by 2015. During the recent period of decreased head CT imaging, the detection of skull fractures (odds ratio [OR]/year, 0.96; 95% confidence interval [CI], 0.95-0.97) and intracranial bleeds (OR/year, 0.96; 95% CI, 0.94-0.97), hospitalization (OR/year, 0.96; 95% CI, 0.95-0.96), neurosurgery (OR/year, 0.91; 95% CI, 0.87-0.95), and revisit (OR/year, 0.98; 95% CI, 0.96-1.00) also decreased, without significant changes in mortality (OR/year, 0.93; 95% CI, 0.84-1.04) or persistent neurologic impairment (OR/year, 1.03; 95% CI, 0.92-1.15).ConclusionsThe recent decline in CT scanning in children with isolated head trauma was associated with a reduction in detection of intracranial abnormalities, and a concomitant decrease in interventions, without measurable patient harm
