OBJECTIVE: To investigate the impact of antiepileptic drug (AED) change and dose titration on the emotional well-being of patients with epilepsy. METHODS: Members of an online epilepsy community were invited to voluntarily participate in an online survey. The cross-sectional anonymous survey consisted of 31 multiple choice questions balanced in terms of variety and positivity/negativity of emotions concerning participants' most recent AED change. To substantiate survey results, spontaneous comments from epilepsy-related online forums and social media websites that mentioned participants' experiences with AED medication changes (termed passive listening statements) were analyzed and categorized by theme...

RATIONALE: Pathways to lung cancer diagnosis and treatment are complex. International evidence shows significant variations in pathways. Qualitative research investigating pathways to lung cancer diagnosis rarely considers both patient and general practitioner views simultaneously. OBJECTIVES: To describe the lung cancer diagnostic pathway, focusing on the perspective of patients and general practitioners about diagnostic and pre-treatment intervals. METHODS: This qualitative study of lung cancer patients and general practitioners in Australia used qualitative interviews or a focus group in which participants responded to a semistructured questionnaire designed to explore experiences of the diagnostic pathway...

Several recent studies have reported on the role of mitogen-activated protein kinase (MAPK3) in plant immune responses. However, little is known about how MAPK3 functions in tomato (Solanum lycopersicum L.) infected with tomato yellow leaf curl virus (TYLCV). There is also uncertainty about the connection between plant MAPK3 and the salicylic acid (SA) and jasmonic acid (JA) defense-signaling pathways. The results of this study indicated that SlMAPK3 participates in the antiviral response against TYLCV. Tomato seedlings were inoculated with TYLCV to investigate the possible roles of SlMAPK1, SlMAPK2, and SlMAPK3 against this virus...

The Pacific herring (Clupea pallasii) population in Prince William Sound, Alaska crashed in 1993 and has yet to recover, affecting food web dynamics in the Sound and impacting Alaskan communities. To help researchers design and implement the most effective monitoring, management, and recovery programs, a Bayesian assessment of Prince William Sound herring was developed by reformulating the current model used by the Alaska Department of Fish and Game. The Bayesian model estimated pre-fishery spawning biomass of herring age-3 and older in 2013 to be a median of 19,410 mt (95% credibility interval 12,150-31,740 mt), with a 54% probability that biomass in 2013 was below the management limit used to regulate fisheries in Prince William Sound...

Purpose Patients who are diagnosed with stage IV metastatic melanoma have an estimated 5-year relative survival rate of only 17%. Randomized controlled trials of recent US Food and Drug Administration-approved immune checkpoint inhibitors-pembrolizumab (PEM), nivolumab (NIVO), and ipilumumab (IPI)-demonstrate improved patient outcomes, but the optimal treatment sequence in patients with BRAF wild-type metastatic melanoma remains unclear. To inform policy makers about the value of these treatments, we developed a Markov model to compare the cost-effectiveness of different strategies for sequencing novel agents for the treatment of advanced melanoma...

Presently, there is high uncertainty in estimates of methane (CH4) emissions from natural gas-fired power plants (NGPP) and oil refineries, two major end users of natural gas. Therefore, we measured CH4 and CO2 emissions at three NGPPs and three refineries using an aircraft-based mass balance technique. Average CH4 emission rates (NGPPs: 140±70 kg/hr; refineries: 580±220 kg/hr, 95% CL) were larger than facility-reported estimates by factors of 21-120 (NGPPs) and 11-90 (refineries). At NGPPs, the percentage of unburned CH4 emitted from stacks (0...

Atmospheric methane (CH4) varied with climate during the Quaternary, rising from a concentration of 375 p.p.b.v. during the last glacial maximum (LGM) 21,000 years ago, to 680 p.p.b.v. at the beginning of the industrial revolution. However, the causes of this increase remain unclear; proposed hypotheses rely on fluctuations in either the magnitude of CH4 sources or CH4 atmospheric lifetime, or both. Here we use an Earth System model to provide a comprehensive assessment of these competing hypotheses, including estimates of uncertainty...

This paper explores a novel clinical framework that is underpinned by a specific philosophical perspective of causation and its utility in clinical practice. A dispositional theory of causation may overcome challenges that clinicians face in complex clinical presentations including those that are medically unexplained. Dispositionalism identifies causes not as regular events necessitating an effect but rather phenomena, which are highly complex, context-sensitive, and which tend toward an effect. Diagnostic uncertainty and causal explanation are significant challenges in terms of clinical reasoning, communication, and the overall therapeutic outcome...

Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and whether functional traits influence the risk of drought-induced mortality. To address these uncertainties, we performed a global meta-analysis of 58 studies of drought-induced forest mortality. Mortality rates were modelled as a function of drought, temperature, biomes, phylogenetic and functional groups and functional traits...

BACKGROUND: The World Health Organization recommends all countries consider screening for H. pylori to prevent gastric cancer. We therefore aimed to estimate the cost-effectiveness of a H. pylori serology-based screening program in New Zealand, a country that includes population groups with relatively high gastric cancer rates. METHODS: A Markov model was developed using life-tables and morbidity data from a national burden of disease study. The modelled screening program reduced the incidence of non-cardia gastric cancer attributable to H...

Health risks from space radiations, particularly from densely ionizing radiations, represent an important challenge for long-ranged manned space missions. Reliable methods are needed for scaling low-LET to high-LET radiation risks for humans, based on animal or in vitro studies comparing these radiations. The current standard metric, relative biological effectiveness (RBE) compares iso-effect doses of two radiations. By contrast, a proposed new metric, radiation effects ratio (RER), compares effects of two radiations at the same dose...

BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for unilateral cleft lip and palate (UCLP), and randomised trials have only occasionally been performed. The Scandcleft Project consists of three trials initiated in 1997. The results at age 5 have been published in the series of reports that precede this manuscript, which aims to distill some of the issues that future trialists may need to address. METHOD: The shared experience of this group of trials is reviewed with reference to the current literature on trial management and, more specifically, trials of surgical technique and timing...

BACKGROUND: Longstanding uncertainty surrounds the selection of surgical protocols for unilateral cleft lip and palate, and randomised trials have only rarely been performed. The Scandcleft Project consists of three trials commenced in 1997 involving ten centres in Denmark, Finland, Norway, Sweden, and the UK. Three groups of centres tested a newly-defined common technique for palatal repair (Arm A) against their local protocols (Arms B, C, D). Arm A was familiar to most of the surgeons in Trial 1, but not to the surgeons in the other Trials...

Understanding structure-function relations in photosystem II (PSII) is important for the development of biomimetic photocatalytic systems. X-ray crystallography, computational modeling, and spectroscopy have played central roles in elucidating the structure and function of PSII. Recent breakthroughs in femtosecond X-ray crystallography offer the possibility of collecting diffraction data from the X-ray free electron laser (XFEL) before radiation damage of the sample, thereby overcoming the main challenge of conventional X-ray diffraction methods...
