Fewer, better pathways for all? Intersectional impacts of rural school consolidation in China's minority regions
Primary school consolidation--the closure of small community schools or their
mergers into larger, better-resourced schools--is emerging as a significant
policy response to changing demographics in middle income countries with large
rural populations. In China, large-scale consolidation took place in the early
21st century. Because officially-recognized minority populations
disproportionately reside in rural and remote areas, minority students were
among those at elevated risk of experiencing school consolidation. We analyze
heterogeneous effects of consolidation on educational attainment and reported
national language ability in China by exploiting variations in closure timing
across villages and cohorts captured in a 2011 survey of provinces and
autonomous regions with substantial minority populations. We consider
heterogeneous treatment effects across groups defined at the intersections of
minority status, gender, and community ethnic composition and socioeconomic
status. Compared to villages with schools, villages whose schools had closed
reported that the schools students now attended were better resourced, less
likely to offer minority language of instruction, more likely to have Han
teachers, farther away, and more likely to require boarding. Much more than Han
youth, ethnic minority youth were negatively affected by closure, in terms of
its impact on both educational attainment and written Mandarin facility.
However, significant penalties accruing to minority youth occurred only in the
poorest villages. Penalties were generally heavier for girls, but in the most
ethnically segregated minority villages, boys from minority families were
highly vulnerable to closure effects on attainment and written Mandarin
facility. Results show that intersections of minority status, gender, and
community characteristics can delineate significant heterogeneities in policy
impacts
Retrospective Evaluation of Dosing Body Weight for Unfractionated Heparin in Obese Patients
Purpose: Using adjusted body weight (AdjBW) for heparin dosing in obese patients is a common but not validated clinical practice. The purpose of this study was to evaluate whether using AdjBW in obese patients would lead to quick achievement of therapeutic activated partial thromboplastin time (aPTT) and low bleeding risk with heparin therapy.
Methods: A retrospective cohort study was conducted in patients that received heparin before and after implementation of a revised heparin protocol that utilized AdjBW for obese patients. The primary outcome was percentage of first aPTT values within the therapeutic range. Secondary outcomes included time to first therapeutic aPTT and clinically significant bleeding.
Results: There was no difference in the primary outcome in obese compared to non-obese patients in the pre-implementation group (11% vs. 15%) or post implementation group (17% vs. 21%). No difference was seen in time to first therapeutic aPTT between obese and non-obese patients in either group. However, obese patients in the post-implementation group achieved therapeutic aPTT significantly faster than obese patients in pre-implementation group (14 vs. 24 hours, p = 0.002). Clinically significant bleeding was higher in obese than non-obese patients prior to implementation (11% vs. 1%, p = 0.01), but no difference was seen after implementation.
Conclusion: Although there was no difference in the first aPTT values, more bleeding was seen in obese patients when actual body weight was used for heparin dose calculation. When AdjBW was used for dosing in obese patients, it was associated with faster achievement of therapeutic aPTT

A Glycine Zipper Motif Mediates the Formation of Toxic Beta-Amyloid Oligomers in Vitro and in Vivo
Background: The b-amyloid peptide (Ab) contains a Gly-XXX-Gly-XXX-Gly motif in its C-terminal region that hasbeen proposed to form a “glycine zipper” that drives the formation of toxic Ab oligomers. We have tested thishypothesis by examining the toxicity of Ab variants containing substitutions in this motif using a neuronal cell line,primary neurons, and a transgenic C. elegans model.Results: We found that a Gly37Leu substitution dramatically reduced Ab toxicity in all models tested, as measuredby cell dysfunction, cell death, synaptic alteration, or tau phosphorylation. We also demonstrated in multiplemodels that Ab Gly37Leu is actually anti-toxic, thereby supporting the hypothesis that interference with glycinezipper formation blocks assembly of toxic Ab oligomers. To test this model rigorously, we engineered second sitesubstitutions in Ab predicted by the glycine zipper model to compensate for the Gly37Leu substitution andexpressed these in C. elegans. We show that these second site substitutions restore in vivo Abtoxicity, furthersupporting the glycine zipper model.Conclusions: Our structure/function studies support the view that the glycine zipper motif present in the Cterminalportion of Ab plays an important role in the formation of toxic Ab oligomers. Compounds designed tointerfere specifically with formation of the glycine zipper could have therapeutic potential
Explantation of infected thoracic endovascular aortic repair
Prosthetic graft infection is a rare and serious complication of thoracic endovascular aortic repair associated with high mortality and posing unique challenges for treatment. The prosthetic graft infection is often identified late as patients present with mild nonspecific symptoms. We describe the successful medical management and surgical explantation of an infected thoracic endograft with an aorta-bronchial fistula, using an inline reconstruction with an antibiotic-soaked synthetic graft. In this report, we provide an example of a patient with an infected thoracic endograft and how inline reconstruction combined with appropriate medical management is an acceptable treatment strategy
Learning to Speak and Act in a Fantasy Text Adventure Game
We introduce a large scale crowdsourced text adventure game as a research
platform for studying grounded dialogue. In it, agents can perceive, emote, and
act whilst conducting dialogue with other agents. Models and humans can both
act as characters within the game. We describe the results of training
state-of-the-art generative and retrieval models in this setting. We show that
in addition to using past dialogue, these models are able to effectively use
the state of the underlying world to condition their predictions. In
particular, we show that grounding on the details of the local environment,
including location descriptions, and the objects (and their affordances) and
characters (and their previous actions) present within it allows better
predictions of agent behavior and dialogue. We analyze the ingredients
necessary for successful grounding in this setting, and how each of these
factors relate to agents that can talk and act successfully
The Stage as a Drawing Board: Zuni Icosahedron’s Architecture Is Art Festival
The multimedia performances of the Architecture Is Art Festival explore the connections of architecture, theatre, and architecture in theatre to voice a number of concerns relating to heritage preservation and technological development, historical memory and current politics. The interrogatives raised by these performances are intimately connected with the ontology of Hong Kong identity and testify to the spirit of traveling—through cultures, media, and disciplines—and the attitude of questioning that has become synonymous with Zuni Icosahedron
The utility of frequent laboratory monitoring for patients on tumor necrosis factor-alpha inhibitors in dermatology
Introduction. Tumor necrosis factor-alpha inhibitors (TNF-ai) are becoming increasingly common to use among patients with skin disease. To safely take these medications, it is recommended to monitor laboratory values routinely; however, the utility of this practice and the risk-benefit of frequent laboratory monitoring has not been fully explored in patients with skin disease. The purpose of this study was to evaluate the necessity of routine laboratory monitoring in patients taking a TNF-ai with a dermatological disease.Â
Methods. Retrospective chart review evaluated laboratory abnormalities (complete blood counts and liver function tests) in adult patients who took a TNF-ai for a dermatologic disease at The University of Kansas Hospital.
Results. There were 27 patients included for a total of 45 entries. The most common skin disease was hidradenitis suppurative (23/45) and infliximab (22/45) was most the commonly used medication. Of the 45 entries, there were only 7 patients that developed abnormal monitoring laboratory values related to initiation of TNF-ai. These abnormalities were transient and most frequently occurred after 12 months with (2/45) resulting in no discontinuation or dose reduction of TNF-ai. One patient discontinued medication due to anemia that did not improve after medication withdrawal.
Conclusions. Laboratory abnormalities due to TNF-ai were infrequent and when they did occur were transient and mild. The study is limited by the small sample size of patients, and larger prospective studies are needed to fully evaluate these findings. However, dermatologists may be able to safely employ less frequent laboratory monitoring for patients on TNF-ai
