We modelled the effects of past and expected future changes in climate (temperature, precipitation), CO2 concentration, nitrogen deposition (N) and ozone (O3) exposure (phytotoxic ozone dose, POD) on carbon (C) sequestration by European forest ecosystems for the period 1900-2050. Tree C sequestration was assessed by using empirical response functions, while soil C sequestration was simulated with the process-based model VSD, combined with the RothC model. We evaluated two empirical growth responses to N deposition (linear and non-linear) and two O3 exposure relationships (linear function with total biomass or net annual increment)...

Objective: Since eliminating hepatitis B in China would need considerable public health resources, the economics problem of the strategy of community-based antiviral treatment for chronic hepatitis B (CHB) has become an important issue. The cost-effectiveness and affordability of the strategy were evaluated in this study. Methods: According to the advocacy on eliminating hepatitis B by WHO and the comprehensive protocol of community based prevention of major infectious diseases and the guideline for CHB prevention and treatment in China, the decision analytic Markov model was constructed with the parameters from national surveys or Meta-analysis...

BACKGROUND: Although non-alcoholic fatty liver disease (NAFLD) is considered to be associated with chronic kidney disease (CKD), long-term follow up data is lacking. We investigated whether NAFLD, as determined by the fatty liver index (FLI), could predict incident CKD in 10-year prospective cohort study. We also assessed the clinical utility of FLI to predict the development of CKD. METHODS: 6,238 adults aged 40 to 69 years without baseline CKD from the Ansan-Ansung cohort were examined...

BACKGROUND: Since multiple myeloma (MM) incurs a substantial economic burden in care management, more and more discussion has been generated in recent years about the costs of novel antimyeloma drugs and their associated value. Because of these costs, economic assessment that quantifies value of care over the long-term is essential. OBJECTIVE: To determine the cost-effectiveness (measured as cost per life-year saved) of front-line novel agent-based therapy use among a cohort of elderly patients with MM in a real-world setting...

BACKGROUND: Patient review and restriction programs (PRRPs), used by state Medicaid programs to limit potential abuse and misuse of opioids and related controlled medications, often restrict members to a single pharmacy for controlled medications. While most states use a restricted pharmacy access model, not all states include restricted prescriber access. Oklahoma Medicaid (MOK) added a restricted prescriber access feature to its PRRP in July 2014. OBJECTIVE: To evaluate the incremental effect that the addition of a prescriber restriction to MOK's pharmacy-only PRRP had on the pharmacy and resource utilization of the enrolled members...

Cell size is specific to each species and impacts cell function. Various phenomenological models for cell size regulation have been proposed, but recent work in bacteria has suggested an 'adder' model, in which a cell increments its size by a constant amount between each division. However, the coupling between cell size, shape and constriction remains poorly understood. Here, we investigate size control and the cell cycle dependence of bacterial growth using multigenerational cell growth and shape data for single Caulobacter crescentus cells...

Although both scholars and lay people are fascinated with charismatic individuals, relatively few theorists have attempted to define charisma. Much of the empirical research examining charisma has focused on leadership. Even within that literature, however, theorists have focused on charisma's outcomes, leaving unarticulated what charisma actually is. Here, we tested an operational conceptualization of charisma in the context of everyday life. Specifically, we proposed that charisma is composed of the interpersonally focused dimensions of influence (the ability to guide others) and affability (the ability to make other people feel comfortable and at ease)...

PURPOSE: To study the relationship between diffuse myocardial fibrosis and complex ventricular arrhythmias (ComVA) in patients with nonischemic dilated cardiomyopathy (NICM). We hypothesized that NICM patients with ComVA would have a higher native myocardial T1 time, suggesting more extensive myocardial diffuse fibrosis. MATERIALS AND METHODS: We prospectively enrolled NICM patients with a history of ComVA (n = 50) and age-matched NICM patients without ComVA (n = 57)...

BACKGROUND: As treatments for chronic hepatitis C are moving away from interferon-containing regimens, the most appropriate allocation of resources to higher cost, interferon-free, direct-acting antiviral (DAA) regimens needs to be assessed. Hepatitis C virus (HCV) genotype 3 is associated with faster disease progression and has fewer treatment options, historically, than other HCV genotypes. This analysis aims to estimate the comparative cost-effectiveness of two recently licenced interferon-free regimens for the treatment of HCV genotype 3...

This study concentrated on the pollution level, sources, and lung cancer risk of PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) in spring in Nanjing, China. The PM2.5 samples were collected in spring of the year 2016 in Nanjing. Sixteen United States Environmental Protection Agency priority PAHs were extracted and analyzed after sampling. The mean concentrations of PAHs and BaPeq were 3.98 ± 1.01 and 0.29 ± 0.08 ng/m(3), respectively, which is a low level among results from regions worldwide. The diurnal variations of PAHs and BaPeq concentrations showed a relatively high level in the early morning, at the morning rush time of work and traffic transportation, and in the evening traffic peak hours...

BACKGROUND: The number of brain metastases (BM) plays an important role in the decision between stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT). METHODS: We analyzed the survival of 5750 SRS-treated BM patients as a function of BM number. Survival analyses were performed using Kaplan-Meier analysis as well as univariate and multivariate Cox proportional hazards models. RESULTS: BM patients were first categorized as those with 1, 2-4, and 5-10 BM based on the scheme proposed by Yamamoto et al (Lancet Oncology 2014)...

Ischemic stroke during nocturnal sleep, known as wake-up stroke (WUS), has been reported to have more severe symptoms and worse outcomes than non-WUS. However, studies on risk factors for WUS are scarce and the association between nocturnal blood pressure (BP) and WUS is unclear. In this study, we used ambulatory blood pressure monitoring (ABPM) to examine the association between WUS and variation in nocturnal BP. A total of 369 patients with ischemic stroke within one week were consecutively enrolled. ABPM was applied 1-2weeks after the ictus because of possible reactive increments of BP; antihypertensive medications were delayed until ABPM...
