Men and women from the STRIDE clinical trial: An assessment of stimulant abstinence symptom severity at residential treatment entry

Background and Objectives Gender‐specific factors associated with stimulant abstinence severity were examined in a stimulant abusing or dependent residential treatment sample (N = 302). Method Bivariate statistics tested gender differences in stimulant abstinence symptoms, measured by participant‐reported experiences of early withdrawal. Multivariate linear regression examined gender and other predictors of stimulant abstinence symptom severity. Results Women compared to men reported greater stimulant abstinence symptom severity. Anxiety disorders and individual anxiety‐related abstinence symptoms accounted for this difference. African American race/ethnicity was predictive of lower stimulant abstinence severity. Discussion and Conclusions Women were more sensitive to anxiety‐related stimulant withdrawal symptoms. Scientific Significance Clinics that address anxiety‐related abstinence symptoms, which more commonly occur in women, may improve treatment outcome. (Am J Addict 2015;XX:XX –XX

Critical Cultural Success Factors for Achieving High Quality Information in an Organization

While information and data quality practitioners are in general agreement that social, cultural, and organizational factors are the most important in determining the success or failure of an organization’s data quality programs, there is little to no existing research quantifying these factors. In this research we build from both our previous research and others’ to distill and clarify those cultural factors which are the Critical Cultural Success Factors (CCSFs) for successful Information and Data Quality programs in an organization. Using the Delphi method for gaining consensus from a group of experts, we distilled fourteen factors down to six and clarified the definitions of those six factors. We begin explaining how these CCSFs fit into Organizational Learning Theory and plan to ultimately define a new system dynamics model incorporating them so that organizations and information quality practitioners can positively affect the success of information and data quality programs

Glucose gel as a potential alternative treatment to infant formula for neonatal hypoglycaemia in Australia

Infant formula is often used as a treatment for neonatal hypoglycaemia in Australia; however, there are concerns that this may jeopardise mother-baby bonding and breastfeeding. Successful use of glucose gel as an alternative treatment for hypoglycaemia has been reported. We wanted to investigate in a pilot study whether the use of glucose gel has the potential to quickly and safely restore normoglycaemia in the infants of diabetic mothers in an Australian setting. Infants with asymptomatic hypoglycaemia were treated with glucose gel (n = 36) and compared to a historical group of infants which had been treated with infant formula (n = 24). Within 15 min of the first treatment, the gel group had a mean blood glucose level (BGL) of 2.6 mmol/L, and 2.7 mmol/L 30 min after the second treatment. This was lower than the BGL after the first treatment for the formula group, which rose to a mean of 2.8 then to 3.2 mmol/L after the second treatment (p = 0.003). In successfully treated infants, administration of the gel resulted in normoglycaemia within 30 min. The likelihood of special care nursery admission was not significantly different between the groups, although we had a small sample size, and our findings should be interpreted with caution. These pilot results provide support for further investigations into the use of glucose gel as an alternative treatment to infant formula

EVALUATION OF A METHOD FOR DETECTION OF BOTH METALLO BETALACTAMASE (MBL) AND EFFLUX PRODUCTION USING CARBONYL CYANIDE 3-CHLOROPHENYLHYDRAZONE (CCCP)±COMBINATION METHOD AMONG PSEUDOMONAS AERUGINOSA ISOLATED FROM CLINICAL SPECIMENS

Objective: To standardize a method for the differential detection of Metallo Betalactamase (MBL) production and efflux pump mechanism using Carbonyl Cyanide 3-ChloroPhenylhydrazone (CCCP) among the clinical isolates of Pseudomonas aeruginosa recovered from ocular specimens.Methods: A total of 110 clinical isolates of Pseudomonas aeruginosa were plated onto Muller-Hinton agar (MHA) plate with CCCP and without CCCP. Carbapenems-Ethylenediaminetetraacetic acid (EDTA) combination disk method was performed on CCCP± plates for individual isolates and the results were compared.Results: Out of 110 clinical isolates of P aeruginosa studied, 11(10%) were tested positive for MBL Production by carbapenem-EDTA combination test/CCCP-test. In which, six isolates showed positive for both efflux and MBL production using CCCP+plate and 5 isolates showed positive only for MBL production.Conclusion: The current study standardized a method for detecting both MBL and efflux mechanism in a single plate consists of CCCP± plate containing antibiotic disk with and without EDTA. Implication of this method in routine diagnostics will help the clinicians to treat the patient with appropriate drug choice and dosage.Â

137,138,139^{137,138,139}La(nn, γ\gamma) cross sections constrained with statistical decay properties of 138,139,140^{138,139,140}La nuclei

The nuclear level densities and $\gamma$-ray strength functions of $^{138,139,140}$La were measured using the $^{139}$La($^{3}$He, $\alpha$), $^{139}$La($^{3}$He, $^{3}$He$^\prime$) and $^{139}$La(d, p) reactions. The particle-$\gamma$ coincidences were recorded with the silicon particle telescope (SiRi) and NaI(Tl) (CACTUS) arrays. In the context of these experimental results, the low-energy enhancement in the A$\sim$140 region is discussed. The $^{137,138,139}$La($n, \gamma)$ cross sections were calculated at $s$- and $p$-process temperatures using the experimentally measured nuclear level densities and $\gamma$-ray strength functions. Good agreement is found between $^{139}$La($n, \gamma)$ calculated cross sections and previous measurements

Determining a Core Curriculum in Surgical Infections for Fellowship Training in Acute Care Surgery Using the Delphi Technique

Background: Recent data highlight the educational, financial, and healthcare benefits of acute care surgery (ACS). These data serve as the impetus to create ACS fellowships, which now are accredited by the American Association for the Surgery of Trauma. However, the core components of a curriculum fundamental for ACS training and that yield competence and proficiency have yet to be determined. Methods: Experts in ACS from the United States (n=86) were asked to propose topics in surgical infectious diseases of potential importance in developing a core curriculum for ACS fellowship training. They were then required to rank these topics in order of importance to identify those considered most fundamental. Results: Thirty-one filters ranking in the highest tertile are proposed as topics of surgical infectious diseases that are fundamental to any curriculum of ACS fellowship training. The majority pertains to aspects of thoracic infections (n=8), although topics of soft tissue infections (n=5) comprised four of the top 10 (40%) filters. Abdominal infections (n=6), the biology of sepsis (n=6), and risk, prevention, and prophylaxis (n=6) completed the list. Conclusion: This study identifies the most important topics of surgical infectious disease that merit consideration for incorporation into a core curriculum of ACS training. Hopefully, this information will assist in the development of ACS fellowships that optimize the training of future ACS surgeons.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140213/1/sur.2012.202.pd

Common activation of canonical Wnt signaling in pancreatic adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDA) is an extremely aggressive malignancy, which carries a dismal prognosis. Activating mutations of the Kras gene are common to the vast majority of human PDA. In addition, recent studies have demonstrated that embryonic signaling pathway such as Hedgehog and Notch are inappropriately upregulated in this disease. The role of another embryonic signaling pathway, namely the canonical Wnt cascade, is still controversial. Here, we use gene array analysis as a platform to demonstrate general activation of the canonical arm of the Wnt pathway in human PDA. Furthermore, we provide evidence for Wnt activation in mouse models of pancreatic cancer. Our results also indicate that Wnt signaling might be activated downstream of Hedgehog signaling, which is an early event in PDA evolution. Wnt inhibition blocked proliferation and induced apoptosis of cultured adenocarcinoma cells, thereby providing evidence to support the development of novel therapeutical strategies for Wnt inhibition in pancreatic adenocarcinoma

Rapid Structural, Kinetic, and Immunochemical Analysis of Alpha-Synuclein Oligomers in Solution.

Oligomers comprised of misfolded proteins are implicated as neurotoxins in the pathogenesis of protein misfolding conditions such as Parkinson's and Alzheimer's diseases. Structural, biophysical, and biochemical characterization of these nanoscale protein assemblies is key to understanding their pathology and the design of therapeutic interventions, yet it is challenging due to their heterogeneous, transient nature and low relative abundance in complex mixtures. Here, we demonstrate separation of heterogeneous populations of oligomeric α-synuclein, a protein central to the pathology of Parkinson's disease, in solution using microfluidic free-flow electrophoresis. We characterize nanoscale structural heterogeneity of transient oligomers on a time scale of seconds, at least 2 orders of magnitude faster than conventional techniques. Furthermore, we utilize our platform to analyze oligomer ζ-potential and probe the immunochemistry of wild-type α-synuclein oligomers. Our findings contribute to an improved characterization of α-synuclein oligomers and demonstrate the application of microchip electrophoresis for the free-solution analysis of biological nanoparticle analytes

Pulmonary Effects of Indoor- and Outdoor-Generated Particles in Children with Asthma

Most particulate matter (PM) health effects studies use outdoor (ambient) PM as a surrogate for personal exposure. However, people spend most of their time indoors exposed to a combination of indoor-generated particles and ambient particles that have infiltrated. Thus, it is important to investigate the differential health effects of indoor- and ambient-generated particles. We combined our recently adapted recursive model and a predictive model for estimating infiltration efficiency to separate personal exposure (E) to PM(2.5) (PM with aerodynamic diameter ≤2.5 μm) into its indoor-generated (E(ig)) and ambient-generated (E(ag)) components for 19 children with asthma. We then compared E(ig) and E(ag) to changes in exhaled nitric oxide (eNO), a marker of airway inflammation. Based on the recursive model with a sample size of eight children, E(ag) was marginally associated with increases in eNO [5.6 ppb per 10-μg/m(3) increase in PM(2.5); 95% confidence interval (CI), −0.6 to 11.9; p = 0.08]. E(ig) was not associated with eNO (−0.19 ppb change per 10μg/m(3)). Our predictive model allowed us to estimate E(ag) and E(ig) for all 19 children. For those combined estimates, only E(ag) was significantly associated with an increase in eNO (E(ag): 5.0 ppb per 10-μg/m(3) increase in PM(2.5;) 95% CI, 0.3 to 9.7; p = 0.04; E(ig): 3.3 ppb per 10-μg/m(3) increase in PM(2.5); 95% CI, −1.1 to 7.7; p = 0.15). Effects were seen only in children who were not using corticosteroid therapy. We conclude that the ambient-generated component of PM(2.5) exposure is consistently associated with increases in eNO and the indoor-generated component is less strongly associated with eNO
