The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element. Here, we applied pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing to reconstruct the evolutionary history of the ST131 clone. PFGE-based cluster analyses suggested that both fluoroquinolone resistance and ESBL production had been acquired by multiple ST131 sublineages through independent genetic events. In contrast, the more robust whole-genome-sequence-based phylogenomic analysis revealed that fluoroquinolone resistance was confined almost entirely to a single, rapidly expanding ST131 subclone, designated H30-R. Strikingly, 91% of the CTX-M-15-producing isolates also …


Strengthening Immigrants' Health Access: Current Opportunities, Leighton C. Ku Dec 2013

Strengthening Immigrants' Health Access: Current Opportunities, Leighton C. Ku

Health Policy and Management Issue Briefs

This brief summarizes key opportunities helping the nation’s newcomers in gaining health insurance coverage and health access that are possible under the current law. Provisions of the Affordable Care Act (ACA) will help millions of legal immigrants gain access to affordable health insurance coverage. At the same time, however, immigrants will also face new responsibilities. Like citizens, lawfully present immigrants will be responsible for having health insurance coverage or paying a tax penalty, although some are exempt. Rules about immigrants’ access to health insurance benefits are often complicated because they depend on specific immigration categories, as well as eligibility for …

Environmental and Occupational Health Faculty Publications

We assessed Escherichia coli ST131 and its H30 and H30-Rx subclones for virulence genes, antimicrobial resistance, and extended-spectrum beta-lactamase (ESBL) type. Although both subclones were associated with ESBL production, H30-Rx isolates had higher resistance scores and were associated specifically with CTX-M-15. Three virulence genes (iha, sat, and iutA) were more prevalent among H30 than non-H30 ST131 isolates. Thus, the H30 and H30-Rx subclones are more antimicrobial resistant and have virulence profiles that are distinct from those of non-H30 ST131 isolates.

Multiple Hypotheses Testing Procedures In Clinical Trials And Genomic Studies, Qing Pan Dec 2013

Multiple Hypotheses Testing Procedures In Clinical Trials And Genomic Studies, Qing Pan

Epidemiology Faculty Publications

We review and compare multiple hypothesis testing procedures used in clinical trials and those in genomic studies. Clinical trials often employ global tests, which draw an overall conclusion for all the hypotheses, such as SUM test, Two-Step test, Approximate Likelihood Ratio test (ALRT), Intersection-Union Test (IUT), and MAX test. The SUM and Two-Step tests are most powerful under homogeneous treatment effects, while the ALRT and MAX test are robust in cases with non-homogeneous treatment effects. Furthermore, the ALRT is robust to unequal sample sizes in testing different hypotheses. In genomic studies, stepwise procedures are used to draw marker-specific conclusions and …

A Profile Of Community Health Center Patients: Implications For Policy, Peter Shin, Carmen Alvarez, Jessica Sharac, Sara J. Rosenbaum, Amanda Van Vleet, Julia Paradise, Rachel Garfield

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

Community health centers are a key source of comprehensive primary care in medically underserved communities across the country, and their role is expected to grow as health coverage expands under the Affordable Care Act (ACA). To sharpen understanding of the health center patient population, this brief compares it to the overall low-income population, using data from the Health Center Patient Survey and the National Health Interview Survey,respectively. The pre-ACA profile of health center patients that emerges sets the stage for measuring change following implementation of the reform law and can inform health center policy, planning, and assessment moving forward.

Staphylococcus aureus clonal complex 398 (CC398) isolates cluster into two distinct phylogenetic clades based on single-nucleotide polymorphisms (SNPs) revealing a basal human clade and a more derived livestock clade. The scn and tet(M) genes are strongly associated with the human and the livestock clade, respectively, due to loss and acquisition of mobile genetic elements. We present canonical single-nucleotide polymorphism (canSNP) assays that differentiate the two major host-associated S. aureus CC398 clades and a duplex PCR assay for detection of scn and tet(M). The canSNP assays correctly placed 88 S. aureusCC398 isolates from a reference collection into …

BACKGROUND: Wealth disparities in child developmental outcomes are well documented in developed countries. We sought to (1) describe the extent of wealth-based neurocognitive development disparities and (2) examine potential mediating factors of disparities among a population-based cohort of children in rural Nepal.

METHODS: We investigated household wealth-based differences in intellectual, executive and motor function of n = 1692 children aged between 7 and 9 years in Nepal. Using linear mixed models, wealth-based differences were estimated before and after controlling for child and household demographic characteristics. We further examined wealth-based differences adjusted for three sets of mediators: child nutritional status, home …


Seeking Value In Medicare: Performance Measurement For Clinical Professionals, Lisa Sprague Oct 2013

Seeking Value In Medicare: Performance Measurement For Clinical Professionals, Lisa Sprague

National Health Policy Forum

The Medicare program, despite its reputation of being a bill payer with little regard to the worth of the services it buys, has begun to put in place a range of programs aimed at assessing quality and value, with more to come. Attention to resource use and cost is nascent. The issues are complex, and it is no surprise that there is a level of contention between providers and regulators, even though both profess commitment to improved quality. This paper summarizes the quality and value programs that apply to physicians and other clinical professionals, as well as programs designed to …

The goal of influenza-like illness (ILI) surveillance is to determine the timing, location and magnitude of outbreaks by monitoring the frequency and progression of clinical case incidence. Advances in computational and information technology have allowed for automated collection of higher volumes of electronic data and more timely analyses than previously possible. Novel surveillance systems, including those based on internet search query data like Google Flu Trends (GFT), are being used as surrogates for clinically-based reporting of influenza-like-illness (ILI). We investigated the reliability of GFT during the last decade (2003 to 2013), and compared weekly public health surveillance with search query …

Assessing The Potential Impact Of The Affordable Care Act On Uninsured Community Health Center Patients: A Nationwide And State-By-State Analysis, Peter Shin, Jessica Sharac, Sara J. Rosenbaum

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

In this brief, we estimate the number of uninsured community health center (CHC) patients who would gain coverage under the Affordable Care Act using data from the 2009 HRSA Survey of CHC patients and 2011 Uniform Data System. We find that were all states to implement the Affordable Care Act Medicaid expansion, an estimated 5 million uninsured health center patients – or two-thirds of all uninsured patients served by CHCs nationally – would be eligible for coverage. However, over one million uninsured patients – 72% of whom live in southern states – who would have been eligible for coverage will …

Providing Outreach And Enrollment Assistance: Lessons Learned From Community Health Centers In Massachusetts, Julia Paradise, Sara J. Rosenbaum, Peter Shin, Jessica Sharac, Carmen Alvarez, Julia Zur, Leighton Ku

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

In 2006, major health care reform legislation was enacted in Massachusetts. In many ways a prototype for the Affordable Care Act (ACA), the Massachusetts law required nearly all state residents to obtain health insurance, and made insurance accessible and affordable by reforming the health insurance market and providing subsidies for coverage through expansions of Medicaid and CHIP and a new program for low-income adults who are not eligible for Medicaid, known as Commonwealth Care. The law also created the “Connector,” which, like the ACA’s health insurance Marketplaces, is designed to facilitate and simplify access to insurance for individuals, families, and …

Epidemiology Of Esophageal Cancer, Yuwei Zhang Sep 2013

Epidemiology Of Esophageal Cancer, Yuwei Zhang

Environmental and Occupational Health Faculty Publications

Esophageal cancer (EsC) is one of the least studied and deadliest cancers worldwide because of its extremely aggressive nature and poor survival rate. It ranks sixth among all cancers in mortality. In retrospective studies of EsC, smoking, hot tea drinking, red meat consumption, poor oral health, low intake of fresh fruit and vegetables, and low socioeconomic status have been associated with a higher risk of esophageal squamous cell carcinoma. Barrett’s esophagus is clearly recognized as a risk factor for EsC, and dysplasia remains the only factor useful for identifying patients at increased risk, for the development of esophageal adenocarcinoma in …

Epidemiology Faculty Publications

Background

Global hypomethylation of repetitive DNA sequences is believed to occur early in tumorigenesis. There is a great interest in identifying factors that contribute to global DNA hypomethylation and associated cancer risk. We tested the hypothesis that plasma S-adenosylmethionine (SAM) level alone or in combination with genetic variation in DNA methyltransferases (DNMT1, DNMT3A andDNMT3B) was associated with global DNA methylation extent at long interspersed nucleotide element-1 (LINE-1) sequences.

Methods

Plasma SAM level and LINE-1 DNA methylation index were measured using stored blood samples collected from 440 healthy Singaporean Chinese adults during 1994-1999. Genetic polymorphisms of …
