Marching orders? : U.S. party platforms and legislative agenda setting 1948-2014

What is the relationship between the priorities expressed in party platforms before an election and the subsequent legislative agenda? The agenda setting literature often deemphasizes the role of political parties in agenda setting. However, parties will often express different issue priorities during elections, and compete based on those priorities. The paper utilizes new data from the U.S. Policy Agendas Project and Wolbrecht (2016) on policy attention in U.S. party platforms to study the relationship between U.S. parties and legislative activities in Congress. A time series cross sectional analysis finds strong evidence to support the proposition that legislative agendas are influenced by the platform of the President’s party in the short term, although the relationship differs for different types of agendas and by issue, and fades over time.Governmen

Information Wars : party elites, think tanks and polarization in Congress

For much of modern history, U.S. political parties adopted a consensus non-partisan knowledge regime, consisting of experts at universities, non-partisan think tanks and government agencies, to inform policymaking decisions. However, after the consensus supported by the knowledge regime enabled the expansion of the scope of federal government domestic policy during the 1950s-1970s period, ideological conservatives rejected the non-partisan regime and created their own alternative knowledge regime centered around a small number of party-aligned think tanks. Democrats followed a few decades later to create their own alternative knowledge regime. These think tanks fill a privileged role advising political parties that is reserved for formal party organizations in most democracies. I argue that they use a variety of strategies, including issue redefinition, activating latent preferences and elite persuasion, to move their party’s positions away from the center and toward the left or right. They published biased policy analysis that often makes claims which conflict with claims made by non-partisan policy analysis. As they become larger and more influential across time or between issues, party-aligned think tanks increase polarization in Congress.Governmen

Gene expression profiling of CD8+ T cells predicts prognosis in patients with Crohn disease and ulcerative colitis.

Crohn disease (CD) and ulcerative colitis (UC) are increasingly common, chronic forms of inflammatory bowel disease. The behavior of these diseases varies unpredictably among patients. Identification of reliable prognostic biomarkers would enable treatment to be personalized so that patients destined to experience aggressive disease could receive appropriately potent therapies from diagnosis, while those who will experience more indolent disease are not exposed to the risks and side effects of unnecessary immunosuppression. Using transcriptional profiling of circulating T cells isolated from patients with CD and UC, we identified analogous CD8+ T cell transcriptional signatures that divided patients into 2 otherwise indistinguishable subgroups. In both UC and CD, patients in these subgroups subsequently experienced very different disease courses. A substantially higher incidence of frequently relapsing disease was experienced by those patients in the subgroup defined by elevated expression of genes involved in antigen-dependent T cell responses, including signaling initiated by both IL-7 and TCR ligation - pathways previously associated with prognosis in unrelated autoimmune diseases. No equivalent correlation was observed with CD4+ T cell gene expression. This suggests that the course of otherwise distinct autoimmune and inflammatory conditions may be influenced by common pathways and identifies what we believe to be the first biomarker that can predict prognosis in both UC and CD from diagnosis, a major step toward personalized therapy

Procedural and interpretive skills of medical students: experiences and attitudes of fourth-year students.

BACKGROUND: Recent data do not exist regarding fourth-year medical students\u27 performance of and attitudes toward procedural and interpretive skills, and how these differ from third-year students\u27. METHOD: Cross-sectional survey conducted in February 2006 of 122 fourth-year students from seven U.S. medical schools, compared with their responses in summer 2005. Students estimated their cumulative performance of 22 skills and reported self-confidence and perceived importance using a five-point Likert-type scale. RESULTS: The response rate was 79% (96/122). A majority reported never having performed cardioversion, thoracentesis, cardiopulmonary resuscitation, blood culture, purified protein derivative placement, or paracentesis. One fifth of students had never performed peripheral intravenous catheter insertion, phlebotomy, or arterial blood sampling. Students reported increased cumulative performance of 17 skills, increased self-confidence in five skills, and decreased perceived importance in three skills (two-sided P \u3c .05). CONCLUSIONS: A majority of fourth-year medical students still have never performed important procedures, and a substantial minority have not performed basic procedures

Development and Evaluation of Machine Learning in Whole-Body Magnetic Resonance Imaging for Detecting Metastases in Patients With Lung or Colon Cancer: A Diagnostic Test Accuracy Study

OBJECTIVES: Whole-body magnetic resonance imaging (WB-MRI) has been demonstrated to be efficient and cost-effective for cancer staging. The study aim was to develop a machine learning (ML) algorithm to improve radiologists' sensitivity and specificity for metastasis detection and reduce reading times. MATERIALS AND METHODS: A retrospective analysis of 438 prospectively collected WB-MRI scans from multicenter Streamline studies (February 2013-September 2016) was undertaken. Disease sites were manually labeled using Streamline reference standard. Whole-body MRI scans were randomly allocated to training and testing sets. A model for malignant lesion detection was developed based on convolutional neural networks and a 2-stage training strategy. The final algorithm generated lesion probability heat maps. Using a concurrent reader paradigm, 25 radiologists (18 experienced, 7 inexperienced in WB-/MRI) were randomly allocated WB-MRI scans with or without ML support to detect malignant lesions over 2 or 3 reading rounds. Reads were undertaken in the setting of a diagnostic radiology reading room between November 2019 and March 2020. Reading times were recorded by a scribe. Prespecified analysis included sensitivity, specificity, interobserver agreement, and reading time of radiology readers to detect metastases with or without ML support. Reader performance for detection of the primary tumor was also evaluated. RESULTS: Four hundred thirty-three evaluable WB-MRI scans were allocated to algorithm training (245) or radiology testing (50 patients with metastases, from primary 117 colon [n = 117] or lung [n = 71] cancer). Among a total 562 reads by experienced radiologists over 2 reading rounds, per-patient specificity was 86.2% (ML) and 87.7% (non-ML) (-1.5% difference; 95% confidence interval [CI], -6.4%, 3.5%; P = 0.39). Sensitivity was 66.0% (ML) and 70.0% (non-ML) (-4.0% difference; 95% CI, -13.5%, 5.5%; P = 0.344). Among 161 reads by inexperienced readers, per-patient specificity in both groups was 76.3% (0% difference; 95% CI, -15.0%, 15.0%; P = 0.613), with sensitivity of 73.3% (ML) and 60.0% (non-ML) (13.3% difference; 95% CI, -7.9%, 34.5%; P = 0.313). Per-site specificity was high (>90%) for all metastatic sites and experience levels. There was high sensitivity for the detection of primary tumors (lung cancer detection rate of 98.6% with and without ML [0.0% difference; 95% CI, -2.0%, 2.0%; P = 1.00], colon cancer detection rate of 89.0% with and 90.6% without ML [-1.7% difference; 95% CI, -5.6%, 2.2%; P = 0.65]). When combining all reads from rounds 1 and 2, reading times fell by 6.2% (95% CI, -22.8%, 10.0%) when using ML. Round 2 read-times fell by 32% (95% CI, 20.8%, 42.8%) compared with round 1. Within round 2, there was a significant decrease in read-time when using ML support, estimated as 286 seconds (or 11%) quicker (P = 0.0281), using regression analysis to account for reader experience, read round, and tumor type. Interobserver variance suggests moderate agreement, Cohen κ = 0.64; 95% CI, 0.47, 0.81 (with ML), and Cohen κ = 0.66; 95% CI, 0.47, 0.81 (without ML). CONCLUSIONS: There was no evidence of a significant difference in per-patient sensitivity and specificity for detecting metastases or the primary tumor using concurrent ML compared with standard WB-MRI. Radiology read-times with or without ML support fell for round 2 reads compared with round 1, suggesting that readers familiarized themselves with the study reading method. During the second reading round, there was a significant reduction in reading time when using ML support

A Chemical Probe for Tudor Domain Protein Spindlin1 to Investigate Chromatin Function.

Modifications of histone tails, including lysine/arginine methylation, provide the basis of a 'chromatin or histone code'. Proteins that con-tain 'reader' domains can bind to these modifications and form specific effector complexes, which ultimately mediate chromatin function. The spindlin1 (SPIN1) protein contains three Tudor methyl-lysine/arginine reader domains and was identified as a putative onco-gene and transcriptional co-activator. Here we report a SPIN1 chemi-cal probe inhibitor with low nanomolar in vitro activity, exquisite selectivity on a panel of methyl reader and writer proteins, and with submicromolar cellular activity. X-ray crystallography showed that this Tudor domain chemical probe simultaneously engages Tudor domains 1 and 2 via a bidentate binding mode. Small molecule inhibition and siRNA knockdown of SPIN1, as well as chemoproteomic studies, iden-tified genes which are transcriptionally regulated by SPIN1 in squa-mous cell carcinoma and suggest that SPIN1 may have a roll in cancer related inflammation and/or cancer metastasis

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT0273570

Bootstrapping the Battle of Britain

The Battle of Britain is the focus of much historical controversy. We show here how the statistical technique of weighted bootstrapping can be used to create a new quantitative basis to help address such controversies. Bootstrapping facilitates the exploration of alternative campaign possibilities with different tactics. This results in comparative probabilities of “victory” for the actual and various counterfactual campaigns, providing a quantified assessment of the likelihood of German achievement of air superiority, thereby facilitating invasion. We find this more likely had the Luftwaffe targeted airfields more heavily, and greatly more likely had Germany brought forward its air campaign

Procedural and interpretive skills of medical students: experiences and attitudes of third-year students

Recent data do not exist on medical students' performance of and attitudes toward procedural and interpretive skills deemed important by medical educators. A total of 171 medical students at seven medical schools were surveyed regarding frequency of performance, self-confidence, and perceived importance of 21 procedural and interpretive skills. Of the 122 responding students (71% response rate), a majority had never performed lumbar puncture, thoracentesis, paracentesis, or blood culture, and students reported lowest self-confidence in these skills. At least one-quarter of students had never performed phlebotomy, peripheral intravenous catheter insertion, or arterial blood sampling. Students perceived all 21 skills as important to learn and perform during medical school. Through the third year of medical school, a majority of students had never performed important procedures, and a substantial minority had not performed basic procedures. Students had low self-confidence in skills they rarely performed, but perceived all skills surveyed as important
