BACKGROUND: A validated prediction model estimates the absolute benefit of intensive versus standard lipid-lowering therapy (LLT) with statins on next major cardiovascular events for individual patients with coronary artery disease. We aimed to assess whether targeting intensive LLT therapy to coronary artery disease patients with the highest predicted absolute benefit is cost-effective compared to treating all with standard or all with intensive LLT. METHODS AND RESULTS: A lifetime Markov model was constructed for coronary artery disease patients (n=10 000) with mean age 61 years...

BACKGROUND: Chlamydia trachomatis is the most common bacterial sexually transmitted infection (STI) in the United States (U.S.) [1] and remains a major public health problem. We determined the cost- benefit of screening all pregnant women aged 15-24 for Chlamydia trachomatis infection compared with no screening. METHODS: We developed a decision analysis model to estimate costs and health-related effects of screening pregnant women for C. trachomatis in a high burden setting (Brooklyn, NY)...

Andrew B Slifkin, Jeffrey R Eder
According to dominant theories of motor control, speed and accuracy are optimized when, on the average, movement endpoints are located at the target center and when the variability of the movement endpoint distributions is matched to the width of the target (viz., Meyer, Abrams, Kornblum, Wright & Smith, 1988). The current study tested those predictions. According to the speed-accuracy trade-off, expanding the range of variability to the amount permitted by the limits of the target boundaries allows for maximization of movement speed while centering the distribution on the target center prevents movement errors that would have occurred had the distribution been off center...

Remediation of potentially toxic trace elements (PTEs) in paddy fields is fundamental for crop safety. In situ application of chemical amendments has been widely adapted because of its cost-effectiveness and environmental safety. The main purpose of this research was to (1) evaluate the reduction in dissolved concentrations of cadmium (Cd) and arsenic (As) with the application of chemical amendments and (2) monitor microbial activity in the soil to determine the remediation efficiency. Three different chemical amendments, lime stone, steel slag, and acid mine drainage sludge, were applied to paddy fields, and rice (Oryza sativa L...

Drinking water reservoirs in the Northern Hemisphere are largely affected by the decadal-long increase in riverine dissolved organic carbon (DOC) concentrations. The removal of DOC in drinking water treatment is costly and predictions are needed to link DOC removal efficiency to its mobilization in catchments, both of which are determined by the molecular composition. To study the effect of hydrological events and land use on the molecular characteristics of dissolved organic matter (DOM), 36 samples from three different catchment areas in the German low mountain ranges, with DOC concentrations ranging from 3 to 32 mg L(-1), were examined...

OBJECTIVES: To develop a framework for the management of complex health care interventions within the Deming continuous improvement cycle and to test the framework in the case of an integrated intervention for multimorbid patients in the Basque Country within the CareWell project. METHODS: Statistical analysis alone, although necessary, may not always represent the practical significance of the intervention. Thus, to ascertain the true economic impact of the intervention, the statistical results can be integrated into the budget impact analysis...

BACKGROUND: Fire blight is an important disease affecting rosaceous plants. The causal agent is the bacteria Erwinia amylovora which is poorly controlled with the use of conventional bactericides and biopesticides. Antimicrobial peptides (AMPs) have been proposed as a new compounds suitable for plant disease control. BP100, a synthetic linear undecapeptide (KKLFKKILKYL-NH2), has been reported to be effective against E. amylovora infections. Moreover, BP100 showed bacteriolytic activity, moderate susceptibility to protease degradation and low toxicity...

This paper proposes a new DAC BIST (digital-to-analog converter built-in self-test) structure using a resistor loop known as a DDEM ADC (deterministic dynamic element matching analog-to-digital converter). Methods for both switch reduction and switch effect reduction are proposed for solving problems related to area overhead and accuracy of the conventional DAC BIST. The proposed BIST modifies the length of each resistor in the resistor loop via a merging operation and reduces the number of switches and resistors...

PURPOSE OF REVIEW: In children, acute global brain injury from traumatic brain injury (TBI) and nontraumatic coma has a substantial cost to the child, the family, and the society. There have historically been relatively few studies looking at long-term cognition and behavioural outcomes. RECENT FINDINGS: Long-term follow-up studies, population-based studies, and meta-analyses are now available for TBI in children as well as adults and suggest that there is a significant cognitive cost, particularly for processing speed, working memory, and intelligence quotient (IQ) in severe TBI...

Deposit contracting may reduce costs and increase efficacy in contingency management interventions. We evaluated two Internet-based deposit contract arrangements for smoking. In Experiment 1, nine participants deposited self-selected amounts that could be earned back for meeting goals. During treatment, participants were reimbursed for breath samples with less than or equal to 6 parts per million carbon monoxide and met the criterion for 47% of samples compared to 1% during baseline. In Experiment 2, 10 participants' deposits were matched up to $50...

The introduction of generic antiretroviral medications in developing countries has resulted in significant CD4 cell restoration, HIV viral decline, and a noteworthy reduction in the time to initiation of therapy. Projection models have also predicted significant cost saving associated with the extensive diffusion of generic antiretrovirals in developed countries. However, some uncertainties on generics have recently been raised. These concerns mainly relate to the adequacy of the study design for bioequivalence testing, the potential for uncontrolled switching from one generic to another, and the loss of adherence if patients switched from fixed-dose coformulations to single components in order to incorporate the new generic drugs...

Theory of local adaptation predicts that non-adapted migrants will suffer increased costs compared to local residents. Ultimately this process can result in the reduction of gene flow and culminate in speciation. Here, we experimentally investigated the relative fitness of migrants in foreign habitats, focusing on diverging lake and river ecotypes of three-spined sticklebacks. A reciprocal transplant experiment performed in the field revealed asymmetric costs of migration: while mortality of river fish was increased under lake conditions, lake migrants suffered from reduced growth relative to river residents...

BACKGROUND: The value of goal-directed fluid therapy in neurosurgical patients, where brain swelling is a major concern, is unknown. The aim of our study was to evaluate the effect of an intraoperative goal-directed fluid restriction (GDFR) strategy on the postoperative outcome of high-risk patients undergoing brain surgery. METHODS: High-risk patients undergoing brain surgery were randomly assigned to a usual care group (control group) or a GDFR group. In the GDFR group, (1) fluid maintenance was restricted to 3 ml/kg/h of a crystalloid solution and (2) colloid boluses were allowed only in case of hypotension associated with a low cardiac index and a high stroke volume variation...

INTRODUCTION: To estimate the cost-effectiveness of insulin degludec (IDeg) versus insulin glargine U100 (IGlar U100) and new-to-market basal insulin analogues in patients with diabetes in order to aid decision-making in a complex basal insulin market. METHODS: A simple, short-term model was used to evaluate the costs and effects of treatment with IDeg versus IGlar U100 over a 12-month period in patients with type 1 (T1DM) and type 2 diabetes (T2DM) from the perspective of the UK National Health Service...

BACKGROUND: Bilateral breast magnetic resonance imaging (MRI) is commonly used in the diagnostic workup of breast cancer (BC) to assess extent of disease and identify occult foci of disease. However, evidence for routine use of pre-operative MRI is lacking. Breast MRI is costly and can lead to unnecessary tests and treatment delays. Clinical care pathways (care paths) are value-based guidelines, which define management recommendations derived by expert consensus and available evidence based data...

Introduction: The U.S. Food and Drug Administration (FDA) has estimated the economic impact of Graphic Warning Labels (GWLs). By omitting the impact on tobacco consumption by pregnant women, the FDA analysis underestimates the economic benefits that would occur from the proposed regulations. There is a strong link between the occurrence of low birth weight babies and smoking while pregnant. Low birth weight babies in turn generate much higher hospital costs than normal birth weight babies. This study aims to fill the gap by quantifying the national hospital cost savings from the reductions in prenatal smoking that will arise if GWLs are implemented in the U...

Visible-light-driven photocatalysis is a promising technology for advanced water treatment, but it usually exhibits a low efficiency. Cu2O is a low-cost semiconductor with narrow band gap, high absorption coefficient and suitable conduction band, but suffers from low charge mobility, poor quantum yield and weak catalytic performance. Herein, the Cu2O catalytic capacity for refractory pollutants degradation is drastically improved by a simple and effective strategy. By virtue of the synergistic effects between photocatalysis and Fenton, a novel and efficient photocatalysis-driven Fenton system, PFC, is originally proposed and experimentally validated using Cu2O/Nano-C hybrids...

OBJECTIVES: To develop and externally validate a predictive model for detection of significant prostate cancer (PC). SUBJECTS AND METHODS: Development of the model was based on prospective cohort including 393 men who underwent mpMRI prior to biopsy. External validity of the model was then examined retrospectively in 198 men from a separate institution whom underwent a mpMRI followed by biopsy for abnormal PSA/DRE. A model was developed with age, PSA, DRE, prostate volume, previous biopsy and PIRADS score as predictors for significant PC (Gleason 7 with >5% grade 4, ≥ 20% cores positive or ≥ 7mm of PC in any core)...

R 2 mapping is a useful tool in blood-oxygen-level dependent (BOLD) fMRI due to its quantitative nature. However, like T 2 -weighted imaging, standard R 2 mapping based on multiecho EPI suffers from geometric distortion, due to strong offresonance near the air-tissue interface. Joint mapping of R 2 and off-resonance can correct the geometric distortion and is less susceptible to motion artifacts. Single-shot joint mapping of R 2 and off-resonance is possible with a rosette trajectory due to its frequent sampling of the k-space center...
