title: Step-Down Parametric Procedures for Testing Correlated Endpoints in a Group-Sequential Trial

description: Maurer and Bretz developed a class of group-sequential weighted Bonferroni procedures with multiple endpoints. Performed as a step-down consonant shortcut to the group-sequential closed testing procedure, the class of procedures of Maurer and Bretz is simple to use for testing multiple endpoints in classical group-sequential settings. This class uses the correlations of sequential statistics, but does not leverage the correlations between endpoints. Thus, there is room for power improvement by suitably using the between-endpoint correlations in a group-sequential trial while maintaining strong control of the family-wise error rate. To this end, we propose a Holm-type step-down exact parametric procedure for situations in which between-endpoint correlations are known a priori or estimable. An adaptive strategy is suggested for situations in which such correlations are unknown. In addition, we briefly discuss a natural group-sequential extension of the partially parametric Seneta–Chen procedure.

title: Chemical fingerprinting identifies <i>Echium vulgare, Eupatorium cannabinum</i> and <i>Senecio</i> spp. as plant species mainly responsible for pyrrolizidine alkaloids in bee-collected pollen

description: Various studies have shown that bee-collected pollen sold as nutritional supplements may contain toxic pyrrolizidine alkaloids (PAs) and, thus, pose a potential health risk for consumers. The level of contamination may vary according to its geographical and botanical origin. Here, the PA content of pollen produced in Switzerland was studied and 32 commercially available bee-collected pollen supplements produced between 2010 and 2014 were analysed. In addition, at what time period bees collect PA-containing pollen was investigated. Hence, this study looked into the occurrence of PAs in pollen samples collected daily during two-to-three consecutive seasons. Furthermore, the PA spectrum in pollen was compared to the spectrum found in flower heads of PA-plants to unambiguously identify plants responsible for PA contamination of pollen. The PA concentration of commercial and daily collected pollen was determined by target analysis using an HPLC-MS/MS system, allowing the detection of 18 different PAs and PA N-oxides found in the genera <i>Echium</i>, <i>Eupatorium</i> and <i>Senecio</i>, while the comparison of the PA spectrum in pollen and flower heads was performed by LC-HR-MS, allowing the detection of all PA types in a sample, including saturated, non-carcinogenic PAs. Of the commercially available pollen, 31% contained PAs with a mean concentration of 319 ng/g, mainly <i>Echium</i>- and <i>Eupatorium</i>-type PAs, while the PA concentrations were below the limit of quantitation (LOQ) in 69% of the pollen samples. Bees collected pollen containing <i>Echium</i>-type PAs mainly in June and July, while they gathered pollen containing <i>Eupatorium</i>-type PAs from mid-July to August. <i>Senecio</i>-type PAs appeared from June to September. Comparison of the PA array in pollen and plants identified <i>E. vulgare</i> and <i>E. cannabinum</i> as the main plants responsible for PA contamination of Swiss bee-collected pollen, and to a lesser extent also identified plants belonging to the genus <i>Senecio</i>.

title: Simulation-based estimation of state-dependent project volatility

description: Project volatility is an essential parameter for real options analysis, and it may also be useful for risk analysis. Many volatility estimation procedures only consider the volatility in the first year of the project. Others consider that different years may have different values of the project volatility. This article takes into account that volatility may change not only with time but also with the state of the project. Two possible definitions for the project volatility are considered, the log-variance and the variance of the project value, and two simulation-based procedures are proposed for estimating state-dependent volatility: two-level simulation and one-and-a-half-level simulation. Computational experiments show that both procedures perform better than the method proposed by Copeland and Antikarov and that the one-and-a-half-level simulation procedure leads to the most accurate estimations of project volatility.

title: Step-down Parametric Procedures for Testing Correlated Endpoints in a Group-Sequential Trial

description: Maurer & Bretz (2013) developed a class of group-sequential weighted Bonferroni procedures with multiple endpoints. Performed as a step-down consonant shortcut to the group-sequential closed testing procedure (Tang & Geller, 1999), the class of procedures of Maurer & Bretz (2013) is simple to use for testing multiple endpoints in classical group-sequential settings. This class utilizes the correlations of sequential statistics, but does not leverage the correlations between endpoints. Thus, there is room for power improvement by suitably using the between-endpoint correlations in a group-sequential trial while maintaining strong control of the familywise error rate. To this end, we propose a Holm-type step-down exact parametric procedure for situations in which between-endpoint correlations are known <i>a priori</i> or estimable. An adaptive strategy is suggested for situations in which such correlations are unknown. In addition, we briefly discuss a natural group-sequential extension of the partially parametric Seneta-Chen procedure (2005).

title: Postharvest physiology of <i>Corchorus olitorius</i> baby leaf growing with different nutrient solutions

description: The storage at 4°C in darkness of <i>Corchorus olitorius</i> L. baby leaf as a ready-to-eat (RTE) vegetable has been studied for the first time. <i>C. olitorius</i> was cultivated in a floating system with different nutrient solutions: standard (NS100%) or halved (NS50%). Several quality factors of this produce were evaluated during season (spring, summer, autumn) considering treatments and days of storage in order to understand the interactions. During storage, sucrose, total and reducing sugars, nitrate, phenolic compounds, anthocyanins, chlorophylls, and carotenoids were measured. Results showed that chlorophylls decreased by 20–30% for both treatments and the changes were statistically different during spring. Carotenoid content did not change until the end of the storage and values ranged from 0.60 g kg<sup>−1</sup> to 0.75 g kg<sup>−1</sup> fresh weight depending on the season. Phenols and anthocyanins decreased within 10 days: −40% of phenols and −50% of anthocyanins, respectively. No interaction between nutrient solutions and storage behaviour was reported. Thus, <i>C. olitorius</i> resulted to be a good source of nutraceutical compounds and it is able to maintain these components during storage. Moreover, the public interest in regards to nutritional and healthy food is rapidly increasing, promoting the discovery of new vegetables, like <i>C. olitorius</i>, for RTE commercialisation.

title: Supplementary Material for: Pooling-Based Genome-Wide Association Study Implicates Gamma-Glutamyltransferase 1 (GGT1) Gene in Pancreatic Carcinogenesis

description: <i>Background/Aims:</i> Knowledge regarding genetic factors that influence pancreatic cancer risk is currently limited. To identify novel pancreatic cancer susceptibility loci, we conducted a two-stage genome-wide association study. <i>Methods:</i> The Affymetrix® Genome-Wide Human SNP Array 6.0 and DNA pooling were used in the screening stage. Twenty-six single-nucleotide polymorphisms (SNPs) were selected for follow-up. These 26 lead SNPs and additionally selected tagSNPs for the regions around the lead SNPs were evaluated by individual genotyping of the pooling population and an independent validation population. <i>Results:</i> Of the lead SNPs, the strongest association was found with rs4820599 located in the γ-glutamyltransferase 1 (<i>GGT1)</i> gene. This SNP was significantly associated with pancreatic cancer risk in the validation population and the combined dataset (p<sub>allele-based</sub> = 0.019 and p<sub>allele-based</sub> = 0.003, respectively). Statistically significant associations were also observed with two <i>GGT1</i> tagSNPs: rs2017869 and rs8135987. Lead SNP rs4820599 is in high linkage disequilibrium (LD; pairwise r<sup>2</sup>: 0.69) and tagSNP rs2017869 is in strong LD (pairwise r<sup>2</sup>: 0.96) with SNP rs5751901, which has been reported to be associated with increased GGT1 serum levels. GGT is expressed in the pancreas and plays a key role in glutathione metabolism. <i>Conclusion:</i> Our results suggest that common variation in the <i>GGT1</i> gene may affect the risk of pancreatic cancer.

title: Supplementary Material for: Clinical Relevance of Patent Foramen Ovale and Atrial Septum Aneurysm in Stroke: Findings of a Single-Center Cross-Sectional Study

description: <i>Background:</i> A significant proportion of ischemic strokes are cryptogenic. In this context, the clinical pertinence of patent foramen ovale (PFO) with and without atrial septum aneurysm (ASA) remains controversial. The aim of this study was to identify how PFO +/–ASA and cryptogenic stroke are associated in a representative sample of stroke patients. <i>Methods:</i> We enrolled all patients (<i>n</i> = 909) with ischemic stroke or transient ischemic attack admitted to the certified stroke unit or neurological intensive care unit of our university medical center who underwent transesophageal echocardiography (TEE) between 2012 and 2014. The baseline characteristics, cardio-/neurovascular risk factors, clinical parameters and TEE findings were analyzed. <i>Results:</i> PFO was present in 26.2%, and PFO was combined with an ASA in 9.9%. In cryptogenic stroke, the prevalence of PFO was higher compared to other etiologies (30.9 vs. 21.9%; <i>p</i> &lt; 0.002). Patients with PFO had lower National Institute of Health Stroke Score (NIHSS) values at admission than those without (2 [0–5] vs. 3 [1–7]; <i>p</i> = 0.001; 95% CI [0.62–0.88]). No difference was found in NIHSS values of PFO patients with or without ASA (2 [0–5] vs. 2 [0–5]; <i>p</i> = 0.683; 95% CI 0.94 [0.68–1.28]). <i>Conclusions:</i> Our study indicates that a detected PFO +/–ASA could exhibit a stroke-relevant finding, if classical risk factors for the stroke were lacking.
