Objective—The goal was to investigate the association between maternal salivary cotinine levels (SCLs) and pregnancy outcome among African Americans smokers
Methods—In a randomized controlled trial conducted in 2001-2004 in Washington, D.C. 714 women (126 active smokers (18%)) were tested for SCLs at the time of recruitment and later in pregnancy. Sociodemographic health risks and pregnancy outcomes were recorded.
Results—Birth weights were significantly lower for infants born to mothers with baseline SCLs of ≥20 ng/ml compared to/ml (p=0.024), ≥50 ng/ml compared to/ml (p=0.002), ≥100 ng/ml compared to/ml (p=0.002), in bivariate analyses. In linear regression analyses adjusting for sociodemographic …

A Randomised-Controlled Trial Of Two Educational Modes For Undergraduate Evidence-Based Medicine Learning In Asia, Janice M. Johnston, Mary Schooling, Gabriel M. Leung
A Randomised-Controlled Trial Of Two Educational Modes For Undergraduate Evidence-Based Medicine Learning In Asia, Janice M. Johnston, Mary Schooling, Gabriel M. Leung
Publications and Research
Background
As the overall evidence for the effectiveness of teaching of evidence based medicine (EBM) is not strong, and the impact of cultural and societal influences on teaching method is poorly understood, we undertook a randomised-controlled trial to test the effectiveness and learning satisfaction with two different EBM teaching methods (usual teaching vs. problem based learning (PBL)) for undergraduate medical students.
Methods
A mixed methods study that included a randomised-controlled crossover trial with two intervention arms (usual teaching and PBL) and a nested qualitative study with focus groups to explore student perceptions of learning and to assess the effectiveness and …
Pivotal Role Of The A2a-Adrenoceptor In Producing Inflammation And Organ Injury In A Rat Model Of Sepsis, Michael Miksa, Padmalaya Des, Mian Zhou, Rongqian Wu, Weifeng Dong, Youxin Ji, Sanna M. Goyert, Thanjavur S. Ravikumar, Ping Wang

Publications and Research
Background: Norepinephrine (NE) modulates the responsiveness of macrophages to proinflammatory stimuli through the activation of adrenergic receptors (ARs). Being part of the stress response, early increases of NE in sepsis sustain adverse systemic inflammatory responses. The intestine is an important source of NE release in the early stage of cecal ligation and puncture (CLP)-induced sepsis in rats, which then stimulates TNF-a production in Kupffer cells (KCs) through the activation of the a2-AR. It is important to know which of the three a2-AR subtypes (i.e., a2A, a2B or a2C) is responsible for the upregulation of TNF-a production. The aim of this …

Suicide rates among soldiers and veterans of Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) have been steadily growing since 2004, with sharp increases observed more recently. Suicides in the Army are a growing concern on Capitol Hill and in the media. Last month, the Senate Armed Services Committee held hearings on the growing incidence of suicides across the armed forces (Federal city digest, 2009, March 18). The Associated Press (AP) underlined the increasing suicide rates among Army personnel (Army reports sharp rise in suicides in January, 2009, Feb. 5). According to the AP, there were 64 suicides in 2004, and …

We often fail to see something that at other times is readily detectable. Because the visual stimulus itself is unchanged, this variability in conscious awareness is likely related to changes in the brain. Here we show that the phase of EEG α rhythm measured over posterior brain regions can reliably predict both subsequent visual detection and stimulus-elicited cortical activation levels in a metacontrast masking paradigm. When a visual target presentation coincides with the trough of an α wave, cortical activation is suppressed as early as 100 ms after stimulus onset, and observers are less likely to detect the target. Thus, …

Background—Environmental tobacco smoke (ETS) exposure during pregnancy contributes to adverse infant health outcomes. Limited previous research has focused on identifying correlates of ETS avoidance. This study sought to identify proximal and more distal correlates of ETS avoidance early in pregnancy among African-American women. Methods—From a sample of low-income, black women (n=1044) recruited in six urban, prenatal care clinics (July 2001–October 2003), cotinine-confirmed nonsmokers with partners, household/ family members, or friends who smoked (n=450) were identified and divided into two groups: any past-7-day ETS exposure and cotinine-confirmed ETS avoidance. Bivariate and multivariate logistic regression analyses identified factors associated with ETS …

Background
In observational studies moderate alcohol use reduces cardio-respiratory mortality. However observational studies may be biased by many factors including residual confounding by unmeasured differences between moderate alcohol users and other groups or by changes in alcohol use with ill-health and aging. We used two different analytic strategies in an under-studied population, i.e. southern Chinese, to provide an assessment of the specific impact of moderate alcohol use on mortality from ischemic heart disease (IHD) and chronic obstructive pulmonary diseases (COPD).
Methods
In a population-based case-control study of all adult deaths in Hong Kong Chinese in 1998, we used adjusted logistic …
Naloxone's Pentapeptide Binding Site On Filamin A Blocks Mu Opioid Receptor–Gs Coupling And Creb Activation Of Acute Morphine, Hoau-Yan Wang, Lindsay H. Burns
Naloxone's Pentapeptide Binding Site On Filamin A Blocks Mu Opioid Receptor–Gs Coupling And Creb Activation Of Acute Morphine, Hoau-Yan Wang, Lindsay H. Burns
Publications and Research
Chronic morphine causes the mu opioid receptor (MOR) to switch its coupling from Gi/o to Gs, resulting in excitatory signaling via both Gαs and its Gβγ dimer. Ultra-low-dose naloxone (NLX) prevents this switch and attenuates opioid tolerance and dependence. This protective effect is mediated via a high-affinity interaction of NLX to a pentapeptide region in c-terminal filamin A (FLNA), a scaffolding protein interacting with MOR. In organotypic striatal slice cultures, we now show that acute morphine induces a dose-dependent Go-to-Gs coupling switch at 5 and 15 min that resolves by 1 hr. The acute Gs coupling induced by 100 µM …
A Role For The Igh Intronic Enhancer E Mu In Enforcing Allelic Exclusion, Fubin Li, Laurel A. Eckhardt
A Role For The Igh Intronic Enhancer E Mu In Enforcing Allelic Exclusion, Fubin Li, Laurel A. Eckhardt
Publications and Research
The intronic enhancer (E mu) of the immunoglobulin heavy chain (IgH) locus is critical for V region gene assembly. To determine E mu's subsequent functions, we created an Igh allele with assembled V(H) gene but with E mu removed. In mice homozygous for this E mu-deficient allele, B cell development was normal and indistinguishable from that of mice with the same V(H) knockin and E mu intact. In mice heterozygous for the E mu-deficient allele, however, allelic exclusion was severely compromised. Surprisingly, this was not a result of reduced suppression of V-DJ assembly on the second allele. Rather, the striking …

Methods. Students from7 high schools in theNewYorkmetropolitan area completed the Columbia Suicide Screen; 489 of the 1729 students screened had positive results. The clinical status of 641 students (73% of those who had screened positive and 23%of thosewho had screened negative) was assessedwithmodules from the Diagnostic Interview Schedule for Children. School professionals nominated by their principal and unaware of students’ screening and diagnostic status were asked to indicate whether they were concerned about the emotional well-being of each participating student. …
