2.  Perceived Role of Motivation and Self-Efficacy in Smoking Cessation: A Secondary Data Analysis 
Addictive behaviors  2016;61:58-61.
Background
This secondary analysis tested whether smokers’ perceived importance of willpower, ability to quit (i.e., self-efficacy), and use of treatment would prospectively predict occurrence of a quit attempt, duration of abstinence, or use of cessation aids
Methods
Smokers (n= 143) who planned to quit sometime in the next 3 months were asked whether, for most smokers, a) willpower is necessary for quitting, b) willpower is sufficient for quitting, c) they could quit anytime, d) they were too addicted to quit, and e) they thought use of aids indicated weakness of character. Smokers then reported quit attempts and abstinence daily for 3 months. No treatment was provided.
Results
The two willpower beliefs were often endorsed (78% and 60% each); the can quit any time and being too addicted beliefs were endorsed less consistently (12% and 35% each); and the belief that use of aids indicates a weakness was rarely endorsed (8%). The beliefs were only modestly correlated. Those who more strongly endorsed the two willpower beliefs or use of aids as a weakness were less likely to make a quit attempt. None of the constructs predicted duration of quit attempt. Seeing treatment as a weakness predicted less use of treatment.
Conclusions
The large majority of smokers believe willpower is necessary and sufficient for quitting and this belief appears to impede quit attempts. Given this is a post-hoc finding, replication tests are needed. If replicated, clinical and media interventions to combat willpower beliefs may increase quit attempts.

3.  Quality Improvement Initiatives Need Rigorous Evaluation: The Case of Pressure Ulcers 
The Partnership for Patients (PfP) and the Agency for Healthcare Research and Quality (AHRQ) have reported a 23.5% decline in hospital-acquired pressure ulcers (HAPU) over 4 years resulting in a cumulative cost savings of more than $10 billion and 49 000 averted deaths, claiming that this significant decline may have been spurred in part by Medicare payment incentives associated with severe (stage 3 or 4) HAPUs. Hospitals with a high rate of severe HAPUs have a payment penalty imposed, creating a financial disincentive to report severe HAPUs, possibly contributing to the magnitude of the reported decline. Despite the financial disincentive to report, the number of severe HAPUs found in claims data over the corresponding 4-year period did not decline but instead remained unchanged. The results from claims data, combined with some flaws in estimating HAPUs, call into question the validity of the decline in HAPUs reported by PfP and AHRQ.

4.  Liver microsomal lipid enhances the activity and redox coupling of colocalized cytochrome P450 reductase‐cytochrome P450 3A4 in nanodiscs 
The Febs Journal  2017;284(14):2302-2319.
The haem‐containing mono‐oxygenase cytochrome P450 3A4 (CYP3A4) and its redox partner NADPH‐dependent cytochrome P450 oxidoreductase (CPR) are among the most important enzymes in human liver for metabolizing drugs and xenobiotic compounds. They are membrane‐bound in the endoplasmic reticulum (ER). How ER colocalization and the complex ER phospholipid composition influence enzyme activity are not well understood. CPR and CYP3A4 were incorporated into phospholipid bilayer nanodiscs, both singly, and together in a 1 : 1 ratio, to investigate the significance of membrane insertion and the influence of varying membrane composition on steady‐state reaction kinetics. Reaction kinetics were analysed using a fluorimetric assay with 7‐benzyloxyquinoline as substrate for CYP3A4. Full activity of the mono‐oxygenase system, with electron transfer from NADPH via CPR, could only be reconstituted when CPR and CYP3A4 were colocalized within the same nanodiscs. No activity was observed when CPR and CYP3A4 were each incorporated separately into nanodiscs then mixed together, or when soluble forms of CPR were mixed with preassembled CYP3A4‐nanodiscs. Membrane integration and colocalization are therefore essential for electron transfer. Liver microsomal lipid had an enhancing effect compared with phosphatidylcholine on the activity of CPR alone in nanodiscs, and a greater enhancing effect on the activity of CPR‐CYP3A4 nanodisc complexes, which was not matched by a phospholipid mixture designed to mimic the ER composition. Furthermore, liver lipid enhanced redox coupling within the system. Thus, natural ER lipids possess properties or include components important for enhanced catalysis by CPR‐CYP3A4 nanodisc complexes. Our findings demonstrate the importance of using natural lipid preparations for the detailed analysis of membrane protein activity.

5.  Variability in, and factors associated with, sizing of polyps by endoscopists at a large community practice 
Endoscopy International Open  2017;5(8):E742-E745.
Background and aims
 Accurate sizing of polyps at time of colonoscopy is critical for determining surveillance intervals. Endoscopists routinely over- or underestimate the size of polyps at colonoscopy. We evaluated the variability in sizing of polyps among multiple endoscopists, and the effect of patient and physician related factors on polyp size estimation in a large community-based practice.
Methods
 Adult patients who underwent a colonoscopy with polypectomy at five endoscopy centers in Minneapolis/St. Paul by one of 52 endoscopists in 2013 were included in this study. Association of patient, physician, and procedure related factors on polyp sizing was assessed.
Results
 In the study time frame, 38 624 colonoscopies were performed at five ambulatory endoscopy centers. Of these, 16 336 had one or more polyp removed with size information available, and were included in this analysis. There was significant inter-physician variation for estimating polyp sizes larger than 5 mm (intraclass correlation coefficient [ICC] 0.13). Older patient age (OR 1.08, 95 %CI 1.06 – 1.11), and male physician gender (OR 1.92, 95 %CI 1.26 – 2.94) were associated with increased odds of physicians sizing polyps as larger in size. Surveillance procedures had a higher odds of larger polyp sizing compared to screening (OR 0.91, 95 %CI 0.86 – 0.97) and diagnostic procedures (OR 0.86, 95 %CI 0.78 – 0.94).
Conclusion
 In a large community setting, variation of polyp sizing estimates exists between physicians. Male physicians were more likely to size polyps as larger in size. Older patients and patients undergoing surveillance procedures were more likely to have polyps that were sized as larger in size.

We recently demonstrated improved sensitivity of prosthetic joint infection (PJI) diagnosis using an automated blood culture bottle system for periprosthetic tissue culture [T. N. Peel et al., mBio 7(1):e01776-15, 2016, https://doi.org/10.1128/mBio.01776-15]. This study builds on the prior research by examining the optimal number of periprosthetic tissue specimens required for accurate PJI diagnosis. Current guidelines recommend five to six, which is impractical. We applied Bayesian latent class modeling techniques for estimating diagnostic test properties of conventional culture techniques (aerobic and anaerobic agars and thioglycolate broth) compared to inoculation into blood culture bottles. Conventional, frequentist receiver operating characteristic curve analysis was conducted as a sensitivity analysis. The study was conducted at Mayo Clinic, Rochester, MN, from August 2013 through April 2014 and included 499 consecutive patients undergoing revision arthroplasty from whom 1,437 periprosthetic tissue samples were collected and processed. For conventional periprosthetic tissue culture techniques, the greatest accuracy was observed when four specimens were obtained (91%; 95% credible interval, 77 to 100%), whereas when using inoculation of periprosthetic tissues into blood culture bottles, the greatest accuracy of diagnosis was observed when three specimens were cultured (92%; 95% credible intervals, 79 to 100%). Results of this study show that the greatest accuracy of PJI diagnosis is obtained when three periprosthetic tissue specimens are obtained and inoculated into blood culture bottles or four periprosthetic tissue specimens are obtained and cultured using standard plate and broth cultures. Increasing the number of specimens to five or more, per current recommendations, does not improve accuracy of PJI diagnosis.

8.  Activation of dominant hemisphere association cortex during naming as a function of cognitive performance in mild traumatic brain injury: Insights into mechanisms of lexical access 
NeuroImage : Clinical  2017;15:741-752.
Patients with a history of mild traumatic brain injury (mTBI) and objective cognitive deficits frequently experience word finding difficulties in normal conversation. We sought to improve our understanding of this phenomenon by determining if the scores on standardized cognitive testing are correlated with measures of brain activity evoked in a word retrieval task (confrontational picture naming). The study participants (n = 57) were military service members with a history of mTBI. The General Memory Index (GMI) determined after administration of the Rivermead Behavioral Memory Test, Third Edition, was used to assign subjects to three groups: low cognitive performance (Group 1: GMI ≤ 87, n = 18), intermediate cognitive performance (Group 2: 88 ≤ GMI ≤ 99, n = 18), and high cognitive performance (Group 3: GMI ≥ 100, n = 21). Magnetoencephalography data were recorded while participants named eighty pictures of common objects. Group differences in evoked cortical activity were observed relatively early (within 200 ms from picture onset) over a distributed network of left hemisphere cortical regions including the fusiform gyrus, the entorhinal and parahippocampal cortex, the supramarginal gyrus and posterior part of the superior temporal gyrus, and the inferior frontal and rostral middle frontal gyri. Differences were also present in bilateral cingulate cortex and paracentral lobule, and in the right fusiform gyrus. All differences reflected a lower amplitude of the evoked responses for Group 1 relative to Groups 2 and 3. These findings may indicate weak afferent inputs to and within an extended cortical network including association cortex of the dominant hemisphere in patients with low cognitive performance. The association between word finding difficulties and low cognitive performance may therefore be the result of a diffuse pathophysiological process affecting distributed neuronal networks serving a wide range of cognitive processes. These findings also provide support for a parallel processing model of lexical access.
Highlights
•Brain activity magnitude during naming is related to cognitive ability in mTBI.•Naming ignites a rapid spread of activity in left cortical association regions.•The activation patterns support a parallel processing model of lexical access.•Low cortical activation may reflect suboptimal recurrent neural networks dynamics.

9.  Recent emergence of carbapenem-resistant organisms in a low prevalence UK setting in London 
Journal of Infection Prevention  2015;17(3):130-134.
Carbapenem-resistant organisms are emerging as a global health threat. The prevalence of CROs in London is largely unknown. A retrospective review of microbiology records indicates an increased in carbapenem-resistant Klebsiella pneumoniae (none in 2011 to 1.3% of 386 in 2013, P = 0.073) and Acinetobacter baumannii (9.1% of 11 in 2011 to 31.2% of 16 in 2013, P = 0.001) in a background of low prevalence at a London hospital. This suggests that CROs may be emerging in our patient population. These increases demand an urgent enhanced surveillance response.

10.  Cardiovascular risk factors—using repeated cross-sectional surveys to assess time trends in socioeconomic inequalities in neighbouring countries 
BMJ Open  2017;7(4):e013442.
Objectives
This study compares trends in socioeconomic inequalities related to key cardiovascular risk factors in neighbouring countries Northern Ireland (NI) and the Republic of Ireland (RoI).
Design
Repeated cross-sectional studies.
Setting
Population based.
Participants
3500–4000 in national surveys in NI and 5000–9000 in RoI, aged 20–69 years.
Measures
Educational attainment was used as a socioeconomic indicator by which the magnitude and direction of trends in inequalities for smoking, diabetes, obesity and physical inactivity in NI and RoI were examined between 1997/1998 and 2007/2011. Gender-specific relative and absolute inequalities were calculated using the Relative Index of Inequality (RII) and Slope Index of Inequality (SII) for both countries.
Results
In both countries, the prevalence of diabetes and obesity increased whereas levels of smoking and physical inactivity decreased over time. In NI relative inequalities increased for obesity (RII 1.1 in males and 2.1 in females in 2010/2011) and smoking (RII 4.5 in males and 4.2 in females in 2010/2011) for both genders and absolute inequalities increased for all risk factors in men and increased for diabetes and obesity in women. In RoI greater inequality was observed in women, particularly for smoking (RII 2.8 in 2007) and obesity (RII 8.2 in 2002) and in men for diabetes (RII 3.2 in 2002).
Conclusions
Interventions to reduce inequalities in risk factors, particularly smoking, obesity and diabetes are encouraged across both countries.

11.  Environmental Cues and Attempts to Change in Daily Cannabis Users: An Intensive Longitudinal Study 
Drug and alcohol dependence  2016;161:15-20.
Introduction
We tested whether environmental cues prompt or inhibit quit or reduction attempts among heavy cannabis users.
Methods
We recruited 196 daily cannabis users who intended to stop or reduce at some point in the next 3 months. Users called an Interactive Voice Response system daily over 3 months to report on cues that might prompt an attempt to quit or reduce (e.g., a request to stop), cues that might inhibit a quit/reduction attempt (e.g., someone offering cannabis), cannabis use, and attempts to stop or reduce cannabis. No treatment was provided.
Results
Our major findings were a) cost and health/psychological problems were the most common prompting cues, and seeing others use and being offered cannabis were the most common inhibiting cues, b) the number of different types of prompting cues prospectively predicted an increase in attempts to change in a dose-related manner, c) more proximal cues appeared to be more strongly related to change, d) requests to stop or reduce, and physical or psychological problems from cannabis, best predicted change attempts, and e) inhibiting cues did not consistently predict the probability of an attempt to change.
Conclusion
These preliminary results suggest several environmental cues prompt attempts to change cannabis use. Thus, interventions to increase the frequency of these cues, and specifically requests to stop or reduce cannabis use, and reinforcing concerns about health and mental adverse events from cannabis use may increase cannabis reduction or cessation.

12.  Fast, fully Bayesian spatiotemporal inference for fMRI data 
Biostatistics (Oxford, England)  2015;17(2):291-303.
We propose a spatial Bayesian variable selection method for detecting blood oxygenation level dependent activation in functional magnetic resonance imaging (fMRI) data. Typical fMRI experiments generate large datasets that exhibit complex spatial and temporal dependence. Fitting a full statistical model to such data can be so computationally burdensome that many practitioners resort to fitting oversimplified models, which can lead to lower quality inference. We develop a full statistical model that permits efficient computation. Our approach eases the computational burden in two ways. We partition the brain into 3D parcels, and fit our model to the parcels in parallel. Voxel-level activation within each parcel is modeled as regressions located on a lattice. Regressors represent the magnitude of change in blood oxygenation in response to a stimulus, while a latent indicator for each regressor represents whether the change is zero or non-zero. A sparse spatial generalized linear mixed model captures the spatial dependence among indicator variables within a parcel and for a given stimulus. The sparse SGLMM permits considerably more efficient computation than does the spatial model typically employed in fMRI. Through simulation we show that our parcellation scheme performs well in various realistic scenarios. Importantly, indicator variables on the boundary between parcels do not exhibit edge effects. We conclude by applying our methodology to data from a task-based fMRI experiment.

13.  Variable High-Pressure-Processing Sensitivities for Genogroup II Human Noroviruses 
Applied and Environmental Microbiology  2016;82(19):6037-6045.
ABSTRACT
Human norovirus (HuNoV) is a leading cause of foodborne diseases worldwide. High-pressure processing (HPP) is one of the most promising nonthermal technologies for the decontamination of viral pathogens in foods. However, the survival of HuNoVs after HPP is poorly understood because these viruses cannot be propagated in vitro. In this study, we estimated the survival of different HuNoV strains within genogroup II (GII) after HPP treatment using viral receptor-binding ability as an indicator. Four HuNoV strains (one GII genotype 1 [GII.1] strain, two GII.4 strains, and one GII.6 strain) were treated at high pressures ranging from 200 to 600 MPa. After treatment, the intact viral particles were captured by porcine gastric mucin-conjugated magnetic beads (PGM-MBs) that contained histo-blood group antigens, the functional receptors for HuNoVs. The genomic RNA copies of the captured HuNoVs were quantified by real-time reverse transcriptase PCR (RT-PCR). Two GII.4 HuNoVs had similar sensitivities to HPP. The resistance of HuNoV strains against HPP ranked as follows: GII.1 > GII.6 > GII.4, with GII.4 being the most sensitive. Evaluation of temperature and matrix effects on HPP-mediated inactivation of HuNoV GII.4, GII.1, and GII.6 strains showed that HuNoV was more easily inactivated at lower temperatures and at a neutral pH. In addition, phosphate-buffered saline (PBS) and minimal essential medium (MEM) can provide protective effects against HuNoV inactivation compared to H2O. Collectively, this study demonstrated that (i) different HuNoV strains within GII exhibited different sensitivities to high pressure, and (ii) HPP is capable of inactivating HuNoV GII strains by optimizing pressure parameters.
IMPORTANCE Human norovirus (HuNoV) is a leading cause of foodborne disease worldwide. Noroviruses are highly diverse, both antigenically and genetically. Genogroup II (GII) contains the majority of HuNoVs, with GII genotype 4 (GII.4) being the most prevalent. Recently, GII.1 and GII.6 have emerged and caused many outbreaks worldwide. However, the survival of these GII HuNoVs is poorly understood because they are uncultivable in vitro. Using a novel receptor-binding assay conjugated with real-time RT-PCR, we found that GII HuNoVs had variable susceptibilities to high-pressure processing (HPP), which is one of the most promising food-processing technologies. The resistance of HuNoV strains to HPP ranked as follows: GII.1 > GII.6 > GII.4. This study highlights the ability of HPP to inactivate HuNoV and the need to optimize processing conditions based on HuNoV strain variability and sample matrix.

14.  A semivarying joint model for longitudinal binary and continuous outcomes 
Semivarying models extend varying coefficient models by allowing some regression coefficients to be constant with respect to the underlying covariate(s). In this paper we develop a semivarying joint modelling framework for estimating the time-varying association between two intensively measured longitudinal response: a continuous one and a binary one. To overcome the major challenge of jointly modelling these responses, namely, the lack of a natural multivariate distribution, we introduce a Gaussian latent variable underlying the binary response. Then we decompose the model into two components: a marginal model for the continuous response, and a conditional model for the binary response given the continuous response. We develop a two-stage estimation procedure and discuss the asymptotic normality of the resulting estimators. We assess the finite-sample performance of our procedure using a simulation study, and we illustrate our method by analyzing binary and continuous responses from the Women’s Interagency HIV Study.

15.  Does the Magnitude of Reduction in Cigarettes Per Day Predict Smoking Cessation? A Qualitative Review 
Nicotine & Tobacco Research  2015;18(1):88-92.
Introduction:
Reduction in cigarettes per day (CPD) aided by nicotine replacement therapy (NRT) increases cessation in smokers; however, it is unclear whether this is due to use of NRT or reduction per se. If the latter, a greater magnitude of reduction in CPD should increase the odds of cessation.
Methods:
The authors searched PubMed, Cochrane, PsychINFO, http://clinicaltrials.gov and their personal libraries for studies on smoking reduction. Seven of the 76 (9%) identified intervention trials and four of 28 naturalistic studies (14%) reported on the magnitude of reduction in relation to the odds of cessation.
Results:
Five of the seven intervention trials and three of the four naturalistic observational (cohort) studies found that increased reduction in CPD was associated with increased cessation. The intervention trials that reported effect sizes found that every 1% decrease in CPD or carbon monoxide was associated with a 3% to 4% increase in the odds of cessation. The naturalistic studies found that ordinal (eg, quartile) increases in participants’ magnitude of reduction in CPD were associated with 50% to 290% increases in the odds of cessation. All of the naturalistic studies and four of the intervention trials included covariates; however, reduction’s association with cessation could still be due to its association with NRT use or motivation.
Conclusion:
Although prospective prediction does not necessarily indicate causality, our findings suggest reduction in CPD is a mechanism of increased cessation in prior NRT-aided reduction studies.

16.  Assessing knowledge about acupuncture: A survey of people with back pain in the UK 
Highlights
•202 adults with back pain completed a survey assessing knowledge of acupuncture.•More than 80% correctly answered questions on efficacy, side-effects, and styles.•Fewer people knew about public sector provision, regulation, or electro-acupuncture.•Addressing these knowledge gaps would improve public awareness of acupuncture.
Objectives
Despite the prevalence of acupuncture treatment in the UK, and the increasing evidence of safety and effectiveness, the information presented to patients by practitioners frequently contains inaccuracies. As knowledge of treatment affects both patient decision-making and treatment outcomes, this study aimed to establish what is known about acupuncture in a sample of people who had, and had not, previously experienced acupuncture.
Design
A 15-item questionnaire was constructed to assess knowledge of acupuncture.
Setting
Online survey of people with a history of back pain.
Results
202 participants completed the questionnaire. 66.8% of the sample was female and 33.2% male, with a mean age of 35 years (range 18–74 years). 87.6% had back pain in the past six months, 44.1% currently. 21.8% had previously received acupuncture, and 69.8% had previously read or heard information about acupuncture. On average participants answered 11.03 of 15 questions about acupuncture correctly (SD = 2.64). Items relating to common concerns about acupuncture, acupuncture efficacy, and types of acupuncture were correctly answered by ≥80% of participants. Participants possessed less knowledge of accessibility, Government legislation, and methods of administration.
Conclusions
The study identified key gaps in knowledge about acupuncture among patients. In particular, many participants were unaware that acupuncture is available from the UK National Health Service and that acupuncturists are not subject to statutory regulation in the UK. These knowledge gaps should be addressed in order to increase people’s understanding of and access to acupuncture.

17.  Outcomes from a Computer-Assisted Intervention Simultaneously Targeting Cannabis and Tobacco Use 
Drug and alcohol dependence  2015;155:134-140.
BACKGROUND
Cannabis users frequently report concurrent tobacco use, and tobacco use is associated with poorer outcomes during treatment for cannabis use disorders (CUD). Interventions that simultaneously target both tobacco and cannabis use disorders may enhance cessation outcomes for either or both substances.
METHODS
This study evaluated an intervention integrating highly effective treatments for cannabis and tobacco use disorders. Thirty-two participants meeting diagnostic criteria for CUD and reporting daily tobacco use were enrolled in a 12-week computer-assisted behavioral treatment for CUD. Participants were encouraged to participate in a tobacco intervention that included a computer-assisted behavioral treatment tailored for tobacco and cannabis co-users, and nicotine-replacement therapy (NRT). Cannabis and tobacco outcomes were evaluated using descriptive statistics and were compared to a historical control group that received treatment for CUD but not tobacco.
RESULTS
Participants achieved 3.6 ± 4.3 consecutive weeks of cannabis abstinence, which was comparable to the historical control group (3.1 ± 4.4). A majority of the sample (78%) completed at least one tobacco module and 44% initiated NRT. Over half (56%) initiated tobacco quit attempts, and 28% were tobacco abstinent for at least two consecutive weeks. Participants showed greater reduction in tobacco use (cigarettes per day) than the historical control group, but differences in tobacco abstinence rates during the final month of treatment were not statistically significant (12.5% vs 4%).
CONCLUSION
Findings suggest that providing a tobacco intervention during treatment for CUD is feasible and may positively impact tobacco use without negatively affecting cannabis use outcomes.

19.  Thermal Inactivation of Enteric Viruses and Bioaccumulation of Enteric Foodborne Viruses in Live Oysters (Crassostrea virginica) 
Human enteric viruses are among the main causative agents of shellfish-associated outbreaks. In this study, the kinetics of viral bioaccumulation in live oysters and the heat stabilities of the predominant enteric viruses were determined both in tissue culture and in oyster tissues. A human norovirus (HuNoV) GII.4 strain, HuNoV surrogates (murine norovirus [MNV-1], Tulane virus [TV]), hepatitis A virus (HAV), and human rotavirus (RV) bioaccumulated to high titers within oyster tissues, with different patterns of bioaccumulation for the different viruses. We tested the thermal stability of each virus at 62, 72, and 80°C in culture medium. The viruses can be ranked from the most heat resistant to the least stable as follows: HAV, RV, TV, MNV-1. In addition, we found that oyster tissues provided protection to the viruses during heat treatment. To decipher the mechanism underlying viral inactivation by heat, purified TV was treated at 80°C for increasing time intervals. It was found that the integrity of the viral capsid was disrupted, whereas viral genomic RNA remained intact. Interestingly, heat treatment leading to complete loss of TV infectivity was not sufficient to completely disrupt the receptor binding activity of TV, as determined by the porcine gastric mucin–magnetic bead binding assay. Similarly, HuNoV virus-like particles (VLPs) and a HuNoV GII.4 strain retained some receptor binding ability following heat treatment. Although foodborne viruses have variable heat stability, 80°C for >6 min was sufficient to completely inactivate enteric viruses in oysters, with the exception of HAV.

20.  copCAR: A Flexible Regression Model for Areal Data 
Non-Gaussian spatial data are common in many fields. When fitting regressions for such data, one needs to account for spatial dependence to ensure reliable inference for the regression coefficients. The two most commonly used regression models for spatially aggregated data are the automodel and the areal generalized linear mixed model (GLMM). These models induce spatial dependence in different ways but share the smoothing approach, which is intuitive but problematic. This article develops a new regression model for areal data. The new model is called copCAR because it is copula-based and employs the areal GLMM’s conditional autoregression (CAR). copCAR overcomes many of the drawbacks of the automodel and the areal GLMM. Specifically, copCAR (1) is flexible and intuitive, (2) permits positive spatial dependence for all types of data, (3) permits efficient computation, and (4) provides reliable spatial regression inference and information about dependence strength. An implementation is provided by R package copCAR, which is available from the Comprehensive R Archive Network, and supplementary materials are available online.

21.  Do Environmental Cues Prompt Attempts to Stop Smoking? A Prospective Natural History Study 
Drug and alcohol dependence  2015;154:146-151.
Introduction
We prospectively tested whether environmental cues prompts attempts to stop smoking.
Methods
We recruited 134 smokers who intended to quit in the next 3 months to complete nightly calls to report cues as well as smoking status, intentions to smoke or not on the next day, and quit attempts over 12 weeks. We provided no treatment.
Results
Participants averaged 6.5 cues/week. The most common cues were embarrassment, cost of cigarettes and messages in the media. The number of cues over a 7-day period predicted the incidence of a quit attempt on the eighth day (e.g. from 1.5% when no cues occurred to 3% when 7 cues occurred during the 7 days). This effect was dose-dependent and was due to both between and within-subject predictors. Five cues predicted quit attempts. A cue that made smokers concerned about the cost of cigarettes appeared to be the strongest cue. Cues on the day prior were not more powerful predictors than more distal cues. Intention to not smoke the next day on the evening prior to the eighth day was a partial mediator of the effect of cues on quit attempts. Retrospective recall of cues was poor.
Conclusions
Our results suggest the occurrence of cues may be a cause of quit attempts and that programs to increase the frequency of cues may increase quit attempts. Further research should examine whether environmental cues and introspective states (e.g. self-efficacy) interact to prompt quit attempts.

22.  Association of Mediterranean diet and cardiorespiratory fitness with the development of pre-diabetes and diabetes: the Coronary Artery Risk Development in Young Adults (CARDIA) study 
Objective
To better understand the association between a modified Mediterranean diet pattern in young adulthood, cardiorespiratory fitness in young adulthood, and the odds of developing pre-diabetes or diabetes by middle age.
Research design and methods
Participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study who did not have pre-diabetes or diabetes at baseline (year 0 (Y0), ages 18–30) and who had data available at the Y0 and year 25 (Y25) visits were included in this analysis (n=3358). Polytomous logistic regression models were used to assess the association between baseline dietary intake and fitness data and odds of pre-diabetes or diabetes by middle age (Y25, ages 43–55).
Results
At the Y25 visit, 1319 participants (39%) had pre-diabetes and 393 (12%) had diabetes. Higher baseline fitness was associated with lower odds of pre-diabetes and of diabetes at Y25. After adjustment for covariates, each SD increment in treadmill duration (181 s) was associated with lower odds for pre-diabetes (OR 0.85, 95% CI 0.75 to 0.95, p=0.005) and for diabetes (OR 0.71, 95% CI 0.60 to 0.85, p=0.0002) when compared to normal glycemia. A modified Mediterranean diet pattern was not associated with either pre-diabetes or diabetes. No interaction between cardiorespiratory fitness and dietary intake was observed, but baseline fitness remained independently associated with incident pre-diabetes and diabetes following adjustment for diet.
Conclusions
Higher cardiorespiratory fitness in young adulthood, but not a modified Mediterranean diet pattern, is associated with lower odds of pre-diabetes and of diabetes in middle age.

The application of biocatalysis for the asymmetric reduction of activated C=C is a powerful tool for the manufacture of high-value chemical commodities. The biocatalytic potential of “-ene” reductases from the Old Yellow Enzyme (OYE) family of oxidoreductases is well-known; however, the specificity of these enzymes toward mainly small molecule substrates has highlighted the need to discover “-ene” reductases from different enzymatic classes to broaden industrial applicability. Here, we describe the characterization of a flavin-free double bond reductase from Nicotiana tabacum (NtDBR), which belongs to the leukotriene B4 dehydrogenase (LTD) subfamily of the zinc-independent, medium chain dehydrogenase/reductase superfamily of enzymes. Using steady-state kinetics and biotransformation reactions, we have demonstrated the regio- and stereospecificity of NtDBR against a variety of α,β-unsaturated activated alkenes. In addition to catalyzing the reduction of typical LTD substrates and several classical OYE-like substrates, NtDBR also exhibited complementary activity by reducing non-OYE substrates (i.e., reducing the exocyclic C=C double bond of (R)-pulegone) and in some cases showing an opposite stereopreference in comparison with the OYE family member pentaerythritol tetranitrate (PETN) reductase. This serves to augment classical OYE “-ene” reductase activity and, coupled with its aerobic stability, emphasizes the potential industrial value of NtDBR. Furthermore, we also report the X-ray crystal structures of the holo-, binary NADP(H)-bound, and ternary [NADP+ and 4-hydroxy-3-methoxycinnamaldehyde (9a)-bound] NtDBR complexes. These will underpin structure-driven site-saturated mutagenesis studies aimed at enhancing the reactivity, stereochemistry, and specificity of this enzyme.

24.  T2* relaxation time of acetabular and femoral cartilage with and without intra-articular Gd-DTPA2- in patients with femoroacetabular impingement 
AJR. American journal of roentgenology  2015;204(6):W695-W700.
Objective
To assess if the presence of intra-articular Gd-DTPA2- during clinical MR arthrography significantly alters the T2* relaxation times of hip articular cartilage in patients with femoroacetabular impingement (FAI).
Materials and Methods
The institutional review board (IRB) approved this study, and informed consents were obtained in this HIPAA compliant study. T2* mapping of ten patient volunteers (F/M: 7/3, age range 14-49, mean±SD = 33.0 ± 12.2 years) with symptomatic FAI was performed before and after intra-articular Gd-DTPA2- administration. Overall 323 regions of interest (ROIs) were defined in acetabular and femoral cartilage each, pre- and post-Gd injection. Agreement of the relaxation times between pre- and post-Gd was assessed using Krippendorff's alpha coefficient and linear regression through the origin.
Results
Pre-Gd and post-Gd T2* relaxation times in both acetabular and femoral cartilage were found to agree strongly. Specifically, estimated Krippendorff's alphas were greater than 0.8 for both acetabular and femoral cartilage, and linear regressions through the origin yielded estimated slopes very close to 1 and R2 values greater than 0.98.
Conclusions
These results indicate that intra-articular injection of Gd-DTPA2-, along the protocol described in this study, has little effect on T2* values of femoral and acetabular cartilage. The results suggest that T2* mapping can be safely performed as an addition to standard clinical hip imaging protocol utilizing Gd-DTPA2-.

25.  Effect of Varenicline on Smoking Cessation Through Smoking Reduction: A Randomized Clinical Trial 
JAMA  2015;313(7):687-694.
Importance
Some cigarette smokers may not be ready to quit immediately but may be willing to reduce cigarette consumption with the goal of quitting.
Objective
To determine efficacy and safety of varenicline for increasing smoking abstinence rates through smoking reduction.
Design, Setting, and Participants
Randomized, blinded, placebo-controlled, multinational clinical trial with a 24-week treatment period and 28-week follow-up conducted between July 2011 and July 2013 at 61 centers in 10 countries. 1510 cigarette smokers not willing or able to quit smoking within the next month but willing to reduce smoking and make a quit attempt within the next 3 months recruited through advertising.
Interventions
Twenty-four weeks of varenicline titrated to 1 mg twice daily or placebo with reduction target of ≥ 50% in number of cigarettes smoked by 4 weeks and ≥ 75% by 8 weeks and a quit attempt by 12 weeks.
Main Outcome Measures
Primary efficacy endpoint was carbon monoxide (CO)-confirmed self-reported abstinence during weeks 15-24. Secondary outcomes were CO-confirmed self-reported abstinence rate for weeks 21-24 and weeks 21-52.
Results
The varenicline group (N = 760) had significantly higher continuous abstinence rates during weeks 15-24 versus placebo (N = 750) (32.1% vs 6.9%; risk difference (RD) 25.2%; 95% CI 21.4%, 29.0%; relative risk (RR) = 4.6; 95% CI 3.5, 6.1). The varenicline group had significantly higher continuous abstinence rates versus placebo during weeks 21-24 (37.8% vs 12.5%; RD 25.2%; 95 CI 21.1%, 29.4%; RR 3.0; 95% CI 2.4, 3.7) and weeks 21-52 (27.0% vs 9.9%; RD 17.1%; 95% CI 13.3%, 20.9%; RR 2.7; 95% CI 2.1, 3.5). Serious adverse events occurred in 3.7% and 2.2% of the varenicline and placebo groups, respectively (P = 0.07).
Conclusions and Relevance
Among cigarette smokers not willing or able to quit within the next month but willing to reduce cigarette consumption and make a quit attempt in the next 3 months, use of varenicline for 24 weeks compared with placebo significantly increased smoking cessation rates through 6 months of follow up. Varenicline offers a treatment option for smokers whose needs are not addressed by clinical guidelines recommending abrupt smoking cessation.
