BACKGROUND: Pulse oximetry screening is a highly accurate tool for the early detection of critical congenital heart disease (CCHD) in newborn infants. As the technique is simple, noninvasive, and inexpensive, it has potentially significant benefits for developing countries. The aim of this study is to provide information for future clinical and health policy decisions by assessing the cost-effectiveness of CCHD screening in China. METHODS AND FINDINGS: We developed a cohort model to evaluate the cost-effectiveness of screening all Chinese newborns annually using 3 possible screening options compared to no intervention: pulse oximetry alone, clinical assessment alone, and pulse oximetry as an adjunct to clinical assessment...

Three data fusion strategies (low-llevel, mid-llevel, and high-llevel) combined with a multivariate classification algorithm (random forest, RF) were applied to authenticate the geographical origins of Panax notoginseng collected from five regions of Yunnan province in China. In low-level fusion, the original data from two spectra (Fourier transform mid-IR spectrum and near-IR spectrum) were directly concatenated into a new matrix, which then was applied for the classification. Mid-level fusion was the strategy that inputted variables extracted from the spectral data into an RF classification model...

BACKGROUND: The Lives Saved Tool (LiST) is a widely used resource for evidence-based decision-making regarding health program scale-up in low- and middle-income countries. LiST estimates the impact of specified changes in intervention coverage on mortality and stunting among children under 5 years of age. We aimed to improve the estimates of the parameters in LiST that determine the rate at which the effects of interventions to prevent stunting attenuate as children get older. METHODS: We identified datasets with serial measurements of children's lengths or heights and used random effects models and restricted cubic splines to model the growth trajectories of children with at least six serial length/height measurements...

BACKGROUND: Soil-transmitted helminth infections are widespread. Many studies have been published on the topic of deworming. The Lives Saved Tool (LiST) is a software package that uses a deterministic mathematical model to estimate the effect of scaling up interventions on maternal and child health outcomes. This review investigates the scope of available evidence for benefits of deworming treatments in order to inform a decision about possible inclusion of deworming as an intervention in LiST...

BACKGROUND AND OBJECTIVES: Prescription Drug Monitoring Programs (PDMPs) can serve as screening tools and support the clinical decision-making process in patients receiving opioids. The objective of the study was to utilize 2014 INSPECT (Indiana's PDMP) data to identify factors that increase patients' likelihood to engage in opioid-related risk behaviors. METHODS: Based on a literature review, four risk behaviors were identified: Receiving >90 morphine milligram equivalents (MME), having >4 opioid prescribers, obtaining opioids from >4 pharmacies, and concurrent use of opioids and benzodiazepines...

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas has a high risk of progressing to invasive pancreatic ductal adenocarcinoma (PDA), but experimental models for IPMN are largely missing. New experimental systems for the molecular characterization of IPMN and for personalized prognosis and treatment options for IPMN are urgently needed. We analyzed the potential use of fertilized chicken eggs for the culture of freshly resected IPMN tissue. We transplanted 49 freshly resected IPMN tissues into eggs and compared the growth characteristics to IPMN tissues transplanted into mice; this was followed by an analysis of histology, morphology and marker expression...

There are limited treatment options available for women with moderate to severe symptoms of uterine fibroids (UFs) who wish to avoid surgery. For these women, treatment with standard pharmaceuticals such as contraceptives is often insufficient to relieve symptoms, and patients may require surgery despite their wish to avoid it. Clinical trials demonstrate that ulipristal acetate 5 mg (UPA) is an effective treatment for this patient group, but its cost-effectiveness has not been assessed in this population. A decision-analytic model was developed to simulate a cohort of patients in this population under treatment with UPA followed by surgery as needed compared to treatment with iron and non-steroidal anti-inflammatory drug (NSAID) followed by surgery as needed (best supportive care, BSC)...

Each year up to 20 000 systematic reviews and meta-analyses are published whose results influence healthcare decisions, thus making the robustness and reliability of meta-analytic methods one of the world's top clinical and public health priorities. The evidence synthesis makes use of either fixed-effect or random-effects statistical methods. The fixed-effect method has largely been replaced by the random-effects method as heterogeneity of study effects led to poor error estimation. However, despite the widespread use and acceptance of the random-effects method to correct this, it too remains unsatisfactory and continues to suffer from defective error estimation, posing a serious threat to decision-making in evidence-based clinical and public health practice...

Two clinical vignettes demonstrate a methodological approach that guides the analyst's attention to metaphors and surfaces that are the focus of different theories. Clinically, the use of different theories expands the metaphorical language with which the analyst tries to make contact with the patient's unconscious life. Metaphorical expressions may be said to relate to each other as the syntax of unconscious fantasy (Arlow 1979). The unconscious fantasy itself represents a metaphorical construction of childhood experience that has persisted, dynamically expressive and emergent into adult life...

Cardiovascular disease has been the major cause of death worldwide. Although the initiation and progression mechanism of the atherosclerosis are similar, the stenotic characteristics and the corresponding medical decisions are different between individuals. In the present study, we performed anatomic and hemodynamic analysis on 8 left coronary arterial trees with 10 identified stenoses. A novel boundary condition method had been implemented for fast computational fluid dynamics simulations and patient-specific three-dimensional printed models had been built for visualizations...

OBJECTIVE: A timely diagnosis of congestive heart failure (CHF) is crucial to evade a life-threatening event. This paper presents a novel probabilistic symbol pattern recognition (PSPR) approach to detect CHF in subjects from their cardiac interbeat (R-R) intervals. METHOD: PSPR discretizes each continuous R-R interval time series by mapping them onto an eight-symbol alphabet and then models the pattern transition behavior in the symbolic representation of the series...

Outcomes for cancer patients have been previously estimated by applying various machine learning techniques to large datasets such as the Surveillance, Epidemiology, and End Results (SEER) program database. In particular for lung cancer, it is not well understood which types of techniques would yield more predictive information, and which data attributes should be used in order to determine this information. In this study, a number of supervised learning techniques is applied to the SEER database to classify lung cancer patients in terms of survival, including linear regression, Decision Trees, Gradient Boosting Machines (GBM), Support Vector Machines (SVM), and a custom ensemble...

BACKGROUND: Most previous studies on healthcare service utilization in low-income countries have not used a multilevel study design to address the importance of community-level women's autonomy. We assessed whether women's autonomy, measured at both individual and community levels, is associated with maternal healthcare service utilization in Ethiopia. METHODS: We analyzed data from the 2005 and 2011 Ethiopia Demographic and Health Surveys (N = 6058 and 7043, respectively) for measuring women's decision-making power and permissive gender norms associated with wife beating...

Concern over contamination of groundwater resources in areas impacted by anthropogenic activities has led to an increasing number of baseline groundwater quality surveys intended to provide context for interpreting water quality data. Flexible screening tools that can parse through these large, regional datasets to identify spatial or temporal changes in water quality are becoming more important to groundwater scientists. One such tool, developed from previous work by the authors, makes use of linear discriminant analysis (LDA) to identify the most probable source of chloride salinity in groundwater samples based on their geochemical fingerprints...

BACKGROUND: HIV epidemic remains a major global health issue. Data from cost-effectiveness analyses base on CD4+ count and morbidity in patients with symptomatic and asymptomatic HIV infection. The approach adopted in these analyses includes many other factors, previously not investigated. Additionally, we evaluate the impact of sexual HIV transmission due to delayed cART on the cost-effectiveness of care. METHODS: A lifetime Markov model (1-month cycle) was developed to estimate the cost per quality adjusted life years (QALY) for a 1- and 3-year delay in starting cART (as compared to starting immediately at linkage to care) lifetime costs, clinical outcomes and cost-effectiveness...
