Bayesian penalized spline models for the analysis of spatio‐temporal count data

In recent years, the availability of infectious disease counts in time and space has increased, and consequently, there has been renewed interest in model formulation for such data. In this paper, we describe a model that was motivated by the need to analyze hand, foot, and mouth disease surveillance data in China. The data are aggregated by geographical areas and by week, with the aims of the analysis being to gain insight into the space–time dynamics and to make short‐term predictions, which will aid in the implementation of public health campaigns in those areas with a large predicted disease burden. The model we develop decomposes disease‐risk into marginal spatial and temporal components and a space–time interaction piece. The latter is the crucial element, and we use a tensor product spline model with a Markov random field prior on the coefficients of the basis functions. The model can be formulated as a Gaussian Markov random field and so fast computation can be carried out using the integrated nested Laplace approximation approach. A simulation study shows that the model can pick up complex space–time structure and our analysis of hand, foot, and mouth disease data in the central north region of China provides new insights into the dynamics of the disease.

Is the SenseWear Armband accurate enough to quantify and estimate energy expenditure in healthy adults?

BACKGROUND The SenseWear Armband (SWA) is a monitor that can be used to estimate energy expenditure (EE); however, it has not been validated in healthy adults. The objective of this paper was to study the validity of the SWA for quantifying EE levels. METHODS Twenty-three healthy adults (age 40-55 years, mean: 48±3.42 years) performed different types of standardized physical activity (PA) for 10 minutes (rest, walking at 3 and 5 km·h-1, running at 7 and 9 km·h-1, and sitting/standing at a rate of 30 cycle·min-1). Participants wore the SWA on their right arm, and their EE was measured by indirect calorimetry (IC) the gold standard. RESULTS There were significant differences between the SWA and IC, except in the group that ran at 9 km·h-1 (>9 METs). Bland-Altman analysis showed a BIAS of 1.56 METs (±1.83 METs) and limits of agreement (LOA) at 95% of -2.03 to 5.16 METs. There were indications of heteroscedasticity (R2 =0.03; P<0.05). Analysis of the receiver operating characteristic (ROC) curves showed that the SWA seems to be not sensitive enough to estimate the level of EE at highest intensities. CONCLUSIONS The SWA is not as precise in estimating EE as IC, but it could be a useful tool to determine levels of EE at low intensities.
Protein Sequence Analysis, Cloning, and Expression of Flammutoxin, a Pore-forming Cytolysin from Flammulina velutipes

Flammutoxin (FTX), a 31-kDa pore-forming cytolysin from Flammulina velutipes, is specifically expressed during the fruiting body formation. We cloned and expressed the cDNA encoding a 272-residue protein with an identical N-terminal sequence with that of FTX but failed to obtain hemolytically active protein. This, together with the presence of multiple FTX family proteins in the mushroom, prompted us to determine the complete primary structure of FTX by protein sequence analysis. The N-terminal 72 and C-terminal 107 residues were sequenced by Edman degradation of the fragments generated from the alkylated FTX by enzymatic digestions with Achromobacter protease I or Staphylococcus aureus V8 protease and by chemical cleavages with CNBr, hydroxylamine, or 1% formic acid. The central part of FTX was sequenced with a surface-adhesive 7-kDa fragment, which was generated by a tryptic digestion of FTX and recovered by rinsing the wall of a test tube with 6 m guanidine HCl. The 7-kDa peptide was cleaved with 12 m HCl, thermolysin, or S. aureus V8 protease to produce smaller peptides for sequence analysis. As a result, FTX consisted of 251 residues, and protein and nucleotide sequences were in accord except for the lack of the initial Met and the C-terminal 20 residues in protein. Recombinant FTX (rFTX) with or without the C-terminal 20 residues (rFTX271 or rFTX251, respectively) was prepared to study the maturation process of FTX. Like natural FTX, rFTX251 existed as a monomer in solution and assembled into an SDS-stable, ring-shaped pore complex on human erythrocytes, causing hemolysis. In contrast, rFTX271, existing as a dimer in solution, bound to the cells but failed to form pore complex. The dimeric rFTX271 was converted to hemolytically active monomers upon the cleavage between Lys251 and Met252 by trypsin.
Individualized Geocoding in Stated Preference Questionnaires: Implications for Survey Design and Welfare Estimation

This paper evaluates the common practice of generic mapping in stated preference valuation, in which identical policy area maps are shown to all respondents. This is compared to a more information-intensive alternative in which individualized maps identify the location of each respondent’s home relative to policy effects. The evaluation is grounded in a theoretical model clarifying the impact of individualized spatial information on preferences for non-market outcomes. The model is illustrated using an application of choice experiments to riparian restoration in coastal Maine. Results characterize valuation contexts for which valid preference elicitation likely requires the provision of individualized spatial information. (JEL Q51, Q57)
Construction of Lyapunov functions for homogeneous second-order systems

Finding an explicit Lyapunov function for stability analysis of a given dynamical system entails the nontrivial task of solving a partial differential inequality. Although many methods for finding Lyapunov functions are available, much remains to be done in this regard since there isn't a universal constructive method for finding simple, explicit Lyapunov functions for dynamical systems with stable equilibria. Homogeneity properties of systems may be used to address this problem since they are capable of reducing the complexity of the equations involved. The present work outlines a method to obtain homogeneous Lyapunov functions for homogeneous second-order systems. In comparison with previous results, the method described here provides explicit Lyapunov functions for a larger set of dynamical systems and greatly reduces the sign-definiteness analysis of the underlying equations.
Pricing Strategies under Behavioral Observational Learning in Social Networks

The increasing pervasiveness of social networks allows users to share purchase behaviors with their online friends. In this study, we examine optimal pricing strategies of a monopolistic firm using an analytical model that accounts for behavioral observational learning in social networks. We show that a seller could potentially control the information available to future customers and induce behavioral observational learning, using an information‐revealing pricing strategy. This result suggests that offering introductory discounts is not always an effective method to boost purchases in social networks. It could prevent the behavioral observational learning that would increase future customers' willingness to pay.
Estimating the Expense of a Mandatory Home- and Community-Based Personal Assistance Services Benefit Under Medicaid

Abstract Personal assistance services (PAS) are essential for many people of all ages with significant disabilities, but these services are not always available to individuals at home or in the community, in large part due to a significant bias toward institutions in the Medicaid program. This study aims to provide an estimate of the expense of a mandatory personal assistance services (PAS) benefit under Medicaid for persons with low incomes, low assets, and significant disability. Design and methods: We use year 2003 data from the Survey of Income and Program Participation to estimate the number of people living in households who would be eligible, based on having an institutional level of need and meeting financial criteria for low income and low assets, combined with additional survey data on annual expenditures under Medicaid programs providing PAS. Results: New expenditures for PAS are estimated to be $1.4–$3.7 billion per year (in 2006 dollars), depending on the rate of participation, for up to half a million new recipients, more than a third of whom would be ages 65 and older. These estimated expenditures are a tenth of those estimated by the Congressional Budget Office for implementing the Medicaid Community-Based Attendant Services and Supports Act (MiCASSA). Implications: Creating a mandatory PAS benefit for those with an institutional level of need is a fiscally achievable policy strategy to redress the imbalance between institutional and community-based services under Medicaid.
Effects of Mometasone Furoate Given Once Daily in the Evening on Lung Function and Symptom Control in Persistent Asthma

BACKGROUND The chronobiology of asthma suggests that, for once-daily dosing, an evening dose may be the most effective treatment paradigm. OBJECTIVE To evaluate the efficacy and safety of mometasone furoate dry powder inhaler (MF-DPI) administered once daily in the evening or twice daily in patients with asthma previously maintained on twice-daily regimens of inhaled corticosteroids. METHODS In this 12-week, multicenter, placebo-controlled trial, 268 subjects ≥12 years of age with inhaled corticosteroid–dependent asthma and baseline forced expiratory volume in 1 second (FEV1) between 50% and 85% of predicted were randomized to receive treatment with MF-DPI 400 μg once daily in the evening, MF-DPI 200 μg twice daily, or placebo. The primary efficacy variable was mean change in FEV1 from baseline to endpoint. Other lung function measures, asthma symptoms, quality of life, and rescue medication use also were assessed. RESULTS At endpoint, mean FEV1 was significantly improved with both MF-DPI doses compared with placebo (p < 0.001). The 2 active treatment groups were statistically indistinguishable from each other. Secondary efficacy variables, including nocturnal awakenings, asthma worsenings, quality of life, and rescue medication use, were also significantly improved for both MF-DPI treatments compared with placebo. Both dosages were well tolerated; no clinically meaningful changes in laboratory values or vital signs were observed. CONCLUSIONS MF-DPI 400 μg once daily in the evening was as effective as MF-DPI 200 μg twice daily in improving pulmonary function, asthma symptoms, and quality of life compared with placebo in subjects previously using twice-daily regimens of an inhaled corticosteroid.
Donepezil improves gait performance in older adults with mild Alzheimer's disease: a phase II clinical trial.

BACKGROUND Gait deficits are prevalent in people with dementia and increase their fall risk and future disability. Few treatments exist for gait impairment in Alzheimer's disease (AD) but preliminary studies have shown that cognitive enhancers may improve gait in this population. OBJECTIVE To determine the efficacy of donepezil, a cognitive enhancer that improves cholinergic activity, on gait in older adults newly diagnosed with AD. METHODS Phase II clinical trial in 43 seniors with mild AD who received donepezil. Participants had not previously received treatment with cognitive enhancers. Primary outcome variables were gait velocity (GV) and stride time variability (STV) under single and dual-task conditions measured using an electronic walkway. Secondary outcomes included attention and executive function. RESULTS After four months of treatment, participants with mild AD improved their GV from 108.4 ± 18.6 to 113.3 ± 19.5 cm/s, p = 0.010; dual-task GV from 80.6 ± 23.0 to 85.3 ± 22.3 cm/s, p = 0.028. Changes in STV were in the expected direction although not statistically significant. Participants also showed improvements in Trail Making Tests A (p = 0.030), B (p = 0.001), and B-A (p = 0.042). CONCLUSION Donepezil improved gait in participants with mild AD. The enhancement of dual-task gait suggests the positive changes achieved in executive function as a possible causal mechanism. This study yielded a clinically significant estimate of effect size; as well, the findings are relevant to the feasibility and ethics considerations for the design of a Phase III clinical trial.
Probucol-Oxidized Products, Spiroquinone and Diphenoquinone, Promote Reverse Cholesterol Transport in Mice

Objective— Oxidized products of probucol, spiroquinone and diphenoquinone, were shown to increase cell cholesterol release and plasma high-density lipoprotein (HDL) by inhibiting degradation of ATP-binding cassette transporter A1. We investigated whether these compounds enhance reverse cholesterol transport in mice. Approach and Results— Spiroquinone and diphenoquinone increased ATP-binding cassette transporter A1 protein (2.8- and 2.6-fold, respectively, P<0.01) and apolipoprotein A-I–mediated cholesterol release (1.4- and 1.4-fold, P<0.01 and P<0.05, respectively) in RAW264.7 cells. However, diphenoquinone, but not spiroquinone, enhanced cholesterol efflux to HDL (+12%, P<0.05), whereas both increased ATP-binding cassette transporter G1 protein, by 1.8- and 1.6-fold, respectively. When given orally to mice, both compounds significantly increased plasma HDL-cholesterol, by 19% and 20%, respectively (P<0.05), accompanied by an increase in hepatic and macrophage ATP-binding cassette transporter A1 but not ATP-binding cassette transporter G1. We next evaluated in vivo reverse cholesterol transport by injecting RAW264.7 cells labeled with 3H-cholesterol intraperitoneally into mice. Both spiroquinone and diphenoquinone increased fecal excretion of the macrophage-derived 3H-tracer, by 25% and 28% (P<0.01 and P<0.05), respectively. spiroquinone/diphenoquinone did not affect fecal excretion of HDL-derived 3H-cholesterol, implying that macrophage-to-plasma was the most important step in spiroquinone/diphenoquinone-mediated promotion of in vivo reverse cholesterol transport. Finally, spiroquinone significantly reduced aortic atherosclerosis in apolipoprotein E null mice when compared with the vehicle. Conclusions— Spiroquinone and diphenoquinone increase functional ATP-binding cassette transporter A1 in both the macrophages and the liver, elevate plasma HDL-cholesterol, and promote overall reverse cholesterol transport in vivo. These compounds are promising as therapeutic reagents against atherosclerosis.
Can Predictors of Response to NSAIDs Be Identified in Patients With Acute Low Back Pain?

ObjectivesThe aim of this study was to determine whether certain patient characteristics could identify people with acute low back pain who were more likely to respond to nonsteroidal anti-inflammatory drugs (NSAIDs), when administered in combination with paracetamol. MethodsThis study involved a secondary analysis of a randomized controlled trial investigating the efficacy of diclofenac in 239 patients presenting to general practitioners for acute low back pain. All patients received advice to “stay active” and take regular paracetamol and then were randomized to receive either diclofenac (50 mg twice daily) or placebo. The primary outcome was days to recovery from pain. The ability of 14 patient characteristics to identify those who respond best to diclofenac was assessed using interaction terms in Cox regression models. ResultsMost of the 14 baseline characteristics investigated were uninformative in identifying those who respond best to diclofenac when added to paracetamol. Patients' sex and levels of fear regarding movement and pain were both independent statistically significant predictors of response to NSAIDs for one definition of recovery but not for the other. The interaction between fear avoidance (physical activity) and NSAIDs treatment was statistically significant (P=0.042, hazard ratio=1.059, 95% confidence interval 1.002 to 1.118) for recovery defined as a pain score of 0 or 1. The interaction between sex and NSAID treatment was statistically significant (P=0.044, hazard ratio=1.755, 95% confidence interval 1.014 to 3.038) for recovery defined as a pain score of 0 or 1 maintained for 7 consecutive days. DiscussionThis study did not find any baseline patient characteristics, which consistently identified patients with acute low back pain who respond best to NSAIDs when provided in addition to paracetamol and advice. A patient's sex and level of fear avoidance may be weak predictors and warrant further prospective investigation.
Gender Differences in the Prevalence of Symptom Disorders and Personality Disorders among Poly-Substance Abusers and Pure Alcoholics

Objective: Gender differences in the prevalence of Axis I and II disorders in poly-substance abusers and pure alcoholics and between these two groups are explored. Method: A consecutive sample (n = 260) of in- and out-patients from two Norwegian counties were assessed by CIDI (Axis I disorders) and MCMI-II (Axis II disorders). Results: Major depression, post-traumatic stress disorder (PTSD), and eating disorders were significantly more prevalent in women than in men. A significantly higher prevalence of antisocial, passive-aggressive, and borderline personality disorders (PD) was observed among poly-substance abusers, whereas pure alcoholics were found to have dependent PDs more often. Female poly-substance abusers differed significantly from all other substance abusers by suffering more often from major depression, simple phobia, PTSD and borderline PD. Male poly-substance abusers more often presented antisocial PD and less often Cluster C disorders than all other substance abusers. Female pure alcoholics more often had major depression and Cluster C disorders than all other substance abusers. Male pure alcoholics presented less often with Axis I disorders, major depression, and PTSD, but more often with Cluster A disorders, in particular schizoid PD, than all other substance abusers. Conclusion: The pattern of comorbid disorders is clearly different between male and female poly-substance abusers and pure alcoholics. This implies that these four subgroups have important differences in their treatment needs.
Determinants of contract duration in outsourced services in the defense sector

ABSTRACT In this article we analyze the contract duration using Transaction Cost Theory with a sample of 283 outsourced services in the Spanish Army during the period 2009–2014.The analysis results show that the greater the specificity of the service, the greater the duration of the contract. In addition, it is obtained that the greater the uncertainty about the behaviour of the provider, the lower the duration of the agreement. These results are consistent with existing literature and empirical works. However, in the case of external uncertainty and incompleteness of the contract, they do not affect the contract duration. This may be because less complex services for shorter terms can be specified better and are less affected by external circumstances. Therefore, the uncertainty should be decomposed and analyzed according to their sources.
Bright Spots, Structure, and Magmatism in Southern Tibet from INDEPTH Seismic Reflection Profiling

INDEPTH seismic reflection profiling shows that the decollement beneath which Indian lithosphere underthrusts the Himalaya extends at least 225 kilometers north of the Himalayan deformation front to a depth of ∼50 kilometers. Prominent reflections appear at depths of 15 to 18 kilometers near where the decollement reflector apparently terminates. These reflections extend north of the Zangbo suture to the Damxung graben of the Tibet Plateau. Some of these reflections have locally anomalous amplitudes (bright spots) and coincident negative polarities implying that they are produced by fluids in the crust. The presence of geothermal activity and high heat flow in the regions of these reflections and the tectonic setting suggest that the bright spots mark granitic magmas derived by partial melting of the tectonically thickened crust.
MOLECULAR ENZYMOLOGY OF THE GLYOXALASE SYSTEM

The glyoxalase system catalyzes the conversion of 2-oxoaldehydes into the corresponding 2-hydroxyacids. This biotransformation involves two separate enzymes, glyoxalase I and glyoxalase II, which bring about two consecutive reactions involving the thiol-containing tripeptide glutathione as a cofactor. The physiologically most important substrate methylglyoxal is converted by glyoxalase I into S-D-lactoyl-glutathione in the first reaction. Subsequently, glyoxalase II catalyzes the hydrolysis of this thiolester into D-lactic acid and free glutathione. The structures of both enzymes have been obtained via molecular cloning, heterologous expression, and X-ray diffraction analysis. Glyoxalase I and glyoxalase II are metalloenzymes and zinc plays an essential role in their diverse catalytic mechanisms. Both enzymes appear linked to a variety of pathological conditions, but further investigations are required to clarify the different physiological aspects of the glyoxalase system.
Peer support for families of children with complex needs: Development and dissemination of a best practice toolkit

BACKGROUND Benefits of peer support interventions for families of children with disabilities and complex medical needs have been described in the literature. An opportunity to create an evidence-informed resource to synthesize best practices in peer support for program providers was identified. The objective of this paper is to describe the key activities used to develop and disseminate the Peer Support Best Practice Toolkit. METHODS This project was led by a team of knowledge translation experts at a large pediatric rehabilitation hospital using a knowledge exchange framework. An integrated knowledge translation approach was used to engage stakeholders in the development process through focus groups and a working group. To capture best practices in peer support, a rapid evidence review and review of related resources were completed. Case studies were also included to showcase practice-based evidence. RESULTS The toolkit is freely available online for download and is structured into four sections: (a) background and models of peer support, (b) case studies of programs, (c) resources, and (d) rapid evidence review. A communications plan was developed to disseminate the resource and generate awareness through presentations, social media, and champion engagement. Eight months postlaunch, the peer support website received more than 2,400 webpage hits. Early indicators suggest high relevance of this resource among stakeholders. CONCLUSIONS The toolkit format was valuable to synthesize and share best practices in peer support. Strengths of the work include the integrated approach used to develop the toolkit and the inclusion of both the published research literature and experiential evidence.
