A review of two journals found that articles using multivariable logistic regression frequently did not report commonly recommended assumptions

Background and Objective: To examine if commonly recommended assumptions for multivariable logistic regression are addressed in two major epidemiological journals. Methods: Ninety-nine articles from the Journal of Clinical Epidemiology and the American Journal of Epidemiology were surveyed for 10 criteria: six dealing with computation and four with reporting multivariable logistic regression results. Results: Three of the 10 criteria were addressed in 50% or more of the articles. Statistical significance testing or confidence intervals were reported in all articles. Methods for selecting independent variables were described in 82%, and specific procedures used to generate the models were discussed in 65%. Fewer than 50% of the articles indicated if interactions were tested or met the recommended events per independent variable ratio of 10: 1. Fewer than 20% of the articles described conformity to a linear gradient, examined collinearity, reported information on validation procedures, goodness-of-fit, discrimination statistics, or provided complete information on variable coding. There was no significant difference (P >.05) in the proportion of articles meeting the criteria across the two journals. Conclusion: Articles reviewed frequently did not report commonly recommended assumptions for using multivariable logistic regression. (C) 2004 Elsevier Inc. All rights reserved.

Incremental cost-effectiveness of exercise echocardiography vs. SPECT imaging for the evaluation of stable chest pain

Aims Technological advances in cardiac imaging have led to dramatic increases in test utilization and consumption of a growing proportion of cardiovascular healthcare costs. The opportunity costs of strategies favouring exercise echocardiography or SPECT imaging have been incompletely evaluated. Methods and results We examined prognosis and cost-effectiveness of exercise echocardiography (n=4884) vs. SPECT (n=4637) imaging in stable, intermediate risk, chest pain patients. Ischaemia extent was defined as the number of vascular territories with echocardiographic wall motion or SPECT perfusion abnormalities. Cox proportional hazard models were employed to assess time to cardiac death or myocardial infarction (MI). Total cardiovascular costs were summed (discounted and inflation-corrected) throughout follow-up. A cost-effectiveness ratio = 2% annual event risk), SPECT ischaemia was associated with earlier and greater utilization of coronary revascularization (P < 0.0001) resulting in an incremental cost-effectiveness ratio of $32 381/LYS. Conclusion Health care policies aimed at allocating limited resources can be effectively guided by applying clinical and economic outcomes evidence. A strategy aimed at cost-effective testing would support using echocardiography in low-risk patients with suspected coronary disease, whereas those higher risk patients benefit from referral to SPECT imaging.

A klímaváltozás és a városi hősziget-effektus együttes hatása a lepkeszúnyog-fajok által terjesztett emberi megbetegedésekre

A Leishmaniasis az egyik legfontosabb, jelenleg gyorsan emelkedő esetszámot mutató, ízeltlábú vektorok által terjesztett betegségcsoport a Földön. A bántalmat okozó egysejtű paraziták átviteléért felelős lepkeszúnyog-fajok (Phlebotomus spp.) jelenlegi geográfiai elterjedését a mérsékelt égöv alatt a téli minimum hőmérsékletek limitálják. Ugyanakkor a városi hősziget-effektus, az épületek hő-emissziója a hőhidakban vagy a jövőben várhatóan melegedő éghajlat a klímaváltozás következményeként megfelelő környezetet teremthet a Phlebotomus fajok megtelepedéséhez e régiókban is. Jelen cikkünk részben korábbi vizsgálatainkon alapul, melyekben a hőhidak, a városi hősziget-effektus és a klímaváltozás, egyes mediterrán dísznövények és a legfontosabb lepkeszúnyog fajok vagy a klímaváltozás hatására módosuló lepkeszúnyog elterjedési területeket modelleztük. Vizsgálataink során kimutattuk, hogy a hőhidak hőmérséklete 3–7 °C-kal magasabb lehet, mint a levegőhőmérséklet az azonos időpontokban, továbbá az antropogén hőemisszió mellett is a jelenben hőszennyezett, de nem fűtött épületekben vagy természetes üregekben van mód a honos lepkeszúnyog fajok áttelelésére Magyarországon. A városi hőszigethatás kézenfekvő magyarázatot adhat arra, hogy a Phlebotomus ariasi legészakabbi előfordulása miért éppen Párizs, a Phlebotomus neglectus elterjedése pedig miért Budapest agglomerációjában található Európában.

Kisspeptina: efeito na maturação in vitro de ovócitos bovinos

This study aimed to evaluate different concentrations of kisspeptin, as well as the interaction of kisspeptin and FSH/LH in vitro maturation and oocyte competence in cattle. In Experiment 1 was determined the minimum concentration of Kisspeptin (Kp) to be used, and in Experiment 2 was evaluated its interection with FSH and LH. The oocytes were collected in a commercial slaughterhouse and only Grade I oocytes were utilized. The oocytes were cultured in TCM-199 medium with bicarbonate plus 10% FBS, sodium pyruvate (22μg/mL), amikacin (83mg/mL), FSH (0.5μg/mL), with different concentrations of Kp, the treatments were: FSH + 0M Kp-10; FSH + 10-7M Kp-10, FSH + 10-6M Kp-10; FSH + 10-5M Kp-10. In Experiment 2, was used better concentration of Kp found in Experiment 1, the following treatments: no hormones; FSH; FSH + Kp-10; FSH + LH; FSH, LH + Kp-10; Kp-10. The oocyte competence was determined by nuclear maturation, mitochondrial distribution, MitoTracker® Orange CMTMRos fluorescence intensity and DCF. The evaluation of nuclear maturation was made after 24 hours incubation and the oocytes were stained with DAPI to determine the nuclear stage (Germinal Vesicle-GV, Metaphase I-MI and Metaphase II-MII).The mitochondrial distribution was classified as peripheral/semiperipheral and diffuse in clusters/granules, evaluated after stained with the MitoTracker® Orange CMTMRos, and was also identified the intensity of it. To determine the intensity of ROS oocytes were stained with DCF. The statistical analysis was performed by SAS GLIMMIX PROC. In Experiment 1 oocytes matured only with the FSH reached a smaller nuclear maturation when compared to those who were matured with Kisspeptin at different concentrations (FSH:13/33; FSH + 10-7M Kp-10: 28/35; FSH + 10-6M Kp-10:30/34; FSH + 10-5M Kp-10:28/32; P=0,0001). There was no statistical difference in mitochondrial distribution between treatments (P>0.05). The fluorescence intensity of MitoTracker did not differ among treatments (P>0.05). The DCF fluorescence intensity was lower when the concentration of Kp was increased in the medium (FSH:12177726,1; FSH + 10-7M Kp-10:10945982,83; FSH + 10-6M Kp-10:9820536,53; FSH + 10-5M Kp-10:9147016,38; P<0,0001). Based in the Experiment 1 results, the concentration of Kp was determined in 10-7M. In Experiment 2 the mitochondrial distribution was different between treatments, because oocytes matured only with Kp or FSH+LH, reached a oocyte competence greater than those maturated with FSH only or without hormone addition (no hormones:66,66%; FSH:66,66%; FSH + Kp-10:75,86%; FSH + LH:91,17%; FSH, LH + Kp-10:82,85%; Kp-10:91,17%; P<0,05). The no hormones resulted in a lower nuclear maturation than the other treatments (no hormones: 5/18; FSH:18/32; FSH + Kp-10:22/29; FSH + LH:26/33; FSH, LH + Kp-10:26/34; Kp-10:25/34; P=0,0094). The fluorescence intensity of probes MitoTracker and DCF was lower when Kp was added to the maturation medium (no hormones:1228363/540069; FSH:2307984/1395751; FSH + Kp-10:1941890/1114948; FSH + LH:2502145/1722376; FSH, LH + Kp-10:2286173/1467782; Kp-10:1859411/979325 P<0,0001). So this is the first study that shows that Kisspeptin stimulates oocyte maturation without the presence of gonadotropins in the maturation medium.

Investigation of electrically active defects at the interface of high-k dielectrics and compound semiconductors

As silicon based devices in integrated circuits reach the fundamental limits of dimensional scaling there is growing research interest in the use of high electron mobility channel materials, such as indium gallium arsenide (InGaAs), in conjunction with high dielectric constant (high-k) gate oxides, for Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) based devices. The motivation for employing high mobility channel materials is to reduce power dissipation in integrated circuits while also providing improved performance. One of the primary challenges to date in the field of III-V semiconductors has been the observation of high levels of defect densities at the high-k/III-V interface, which prevents surface inversion of the semiconductor. The work presented in this PhD thesis details the characterization of MOS devices incorporating high-k dielectrics on III-V semiconductors. The analysis examines the effect of modifying the semiconductor bandgap in MOS structures incorporating InxGa1-xAs (x: 0, 0.15. 0.3, 0.53) layers, the optimization of device passivation procedures designed to reduce interface defect densities, and analysis of such electrically active interface defect states for the high-k/InGaAs system. Devices are characterized primarily through capacitance-voltage (CV) and conductance-voltage (GV) measurements of MOS structures both as a function of frequency and temperature. In particular, the density of electrically active interface states was reduced to the level which allowed the observation of true surface inversion behavior in the In0.53Ga0.47As MOS system. This was achieved by developing an optimized (NH4)2S passivation, minimized air exposure, and atomic layer deposition of an Al2O3 gate oxide. An extraction of activation energies allows discrimination of the mechanisms responsible for the inversion response. Finally a new approach is described to determine the minority carrier generation lifetime and the oxide capacitance in MOS structures. The method is demonstrated for an In0.53Ga0.47As system, but is generally applicable to any MOS structure exhibiting a minority carrier response in inversion.

(Table 1) Mean annual ground temperatures and description of permafrost boreholes in Russia

The results of the International Permafrost Association's International Polar Year Thermal State of Permafrost (TSP) project are presented based on field measurements from Russia during the IPY years (2007-09) and collected historical data. Most ground temperatures measured in existing and new boreholes show a substantial warming during the last 20 to 30 years. The magnitude of the warming varied with location, but was typically from 0.5°C to 2°C at the depth of zero annual amplitude. Thawing of Little Ice Age permafrost is ongoing at many locations. There are some indications that the late Holocene permafrost has begun to thaw at some undisturbed locations in northeastern Europe and northwest Siberia. Thawing of permafrost is most noticeable within the discontinuous permafrost domain. However, permafrost in Russia is also starting to thaw at some limited locations in the continuous permafrost zone. As a result, a northward displacement of the boundary between continuous and discontinuous permafrost zones was observed. This data set will serve as a baseline against which to measure changes of near-surface permafrost temperatures and permafrost boundaries, to validate climate model scenarios, and for temperature reanalysis.

Benthic foraminiferal abundances in Late Cretaceous sediments of the Tethys

Benthic foraminiferal distribution patterns throughout the late Maastrichtian Tethyan deep sea are analyzed. Many species are ubiquitously distributed throughout this region and therefore it is hard to assess their ecological preferences. However, five species show distribution patterns, which suggest that they may have distinctive paleoenvironmental preferences. These preferences are interpreted from hypothesized surface circulation and upwelling patterns. Additional information comes from Recent benthic foraminiferal ecology and from responses to the Cretaceous/Paleogene (k/Pg) boundary event. This enables us to assess the ecological preferences of these late Maastrichtian taxa, and establish them as ecological-marker (ecomarker) species for paleoenvironmental interpretation of the late Maastrichtian bathyal-abyssal Tethyan realm. (1) Eouvigerina subsculpturu is suggested to be indicative of reasonably oxygenated upper-middle bathyal environments, though with high abundance of utilizable organic matter. (2) Sliteria varsoviensis is linked to areas of late Maastrichtian upwelling and seems to have been an epibenthic species with an opportunistic life mode. (3) Guvelinellu beccuriiformis and (4) Nuttullides truempyi are considered to be indicative of oligotrophic conditions unless they occur with a large proportion of endobenthic morphotypes. (5) Guvelinellu pertusu is proposed to indicate neritic-middle bathyal environments of the 'boreal' realm, which might be influenced by more seasonal food-fluxes and by higher oxygen levels than similar settings in the (sub)tropics. Finally, the anomalous high abundances of the buliminid species Sitella cf. plunu in deep open ocean environments is discussed in terms of possible mechanisms permitting such a (morphologically) opportunistic species to thrive in such an assumedly oligotrophic environment.

Nucleonic intensities investigated during the Atlantic Expedition IQSY 1965 of RV "Meteor" (Appendix)

The nucleonic component of the cosmic rays has been measured by the German research vessel "Meteor" during the Atlantic Expedition IQSY 1965. The pressure corrected intensities fit well the rigidity calculations of Kondo and Kodamo. In this way we confirm the earth's magnetic field model used by these authors. Two positions of the cosmic ray equator have been determined at 29,7 °W (6,5 ± 1) °N and at 19 °W (7 ± 1) °N. These positions agree with the calculated values of Kondo and Kodamo. The total latitude effect of the nucleonic component amounts to 1.74 and 1.76. The measurements were carried out at solar minima activity. Using the values of latitude measurements at maxima solar activity the degree of modulation of the primary cosmic rays was determined in the rigidity range 2 - 13 GV. For rigidity values above 6 GV the modulation remains constant to 20 %.

Fórmula CUN-BAE y factores bioquímicos como marcadores predictivos de obesidad y enfermedad cardiovascular en pacientes pre y post gastrectomía vertical

Introducción: El Índice de Masa Corporal (IMC) es uno de los parámetros más utilizados en cirugía bariátrica. Sin embargo, no discrimina el peso asociado a adiposidad. La fórmula CUN-BAE es una ecuación que permite calcular el Porcentaje de Grasa Corporal (PGC) o adiposidad, basándose en valores fáciles de disponer (edad, sexo e IMC). Con esta nueva clasificación muchos de los sujetos considerados con normopeso o sobrepeso (IMC ≤ 30 kg/m²) en realidad tienen un PGC alto y presentan comorbilidades asociadas a la obesidad. El objetivo de este estudio es evaluar PGC cuantificado mediante fórmula CUN-BAE como marcador predictivo de riesgo cardiovascular en pacientes obesos mórbidos, antes y después de ser sometidos a Gastrectomía Vertical (GV). Material y métodos: Realizamos un estudio observacional retrospectivo de mujeres intervenidas de GV entre 2007 y 2012 en el Hospital General Universitario de Elche, calculando el PGC mediante la fórmula CUN-BAE de forma preoperatoria y 12 meses tras la intervención. Se correlacionaron estos valores con diferentes parámetros metabólicos y de riesgo cardiovascular. Resultados: Se estudiaron 50 mujeres. Preoperatoriamente, el IMC medio de 50,4 ± 7,4 kg/m² y PGC del 54,8 ± 3%. Al año de la intervención, el IMC medio era de 27,7 ± 2,6 y el PGC 39,4 ± 3,7%. La PGC se correlacionó significativamente con 3 factores bioquímicos asociados con mayor riesgo cardiovascular (cortisol, vitamina D y cociente TG/HDL). Conclusión: la adiposidad, según la fórmula CUN-BAE, y el análisis de factores bioquímicos predictivos de obesidad, de forma conjunta suponen herramientas útiles para valorar el riesgo de enfermedad cardiovascular, después de GV.

Interação genótipo-ambiente na densidade de gemas e comprimento de ramos de pessegueiro

The instability of environment between years in climates of subtropical regions difficult to obtain peach trees genotypes with wide adaptation and stable production, contributing to poor crop. The climate instability can affect development stages as flower bud and vegetative bud formation. The factors understanding that control the bud formation, presents elementary importance for effective solutions search to these problems. The objective this work is verify the temperature effect, relative humidity and rainfall on bud density and length shoot (Brindilas) and identify genotypes with more adaptability and stability for this character. Was used 12 peach trees genotypes growing in experimental orchard in the Technology Federal of Paraná State University, Campus Pato Branco with Cfa Köppen climate according to the classification. Data of rainfall, hourly temperature were collected by the weather station of Simepar. They were used three plants for genotype (rehearsal), identify five shoots per tree, in May of each year. Were carried analyzes of length shoot CR (cm), count number of flower bud (GF) and vegetative bud (GV). Also calculated the relationship between GF/GV and flower bud density and vegetative bud density. Evaluations were performer annual 2007-2014. With these data adaptability and stability analyzes were performed using Biplot methodology and correlations analyzes (Pearson) with climates variables. They used the weather data to calculate the sums of hours with temperatures below 20 °C, temperatures between 20-25 °C, temperature between 25-30 °C and temperature above 30 °C, considering the period of August 1fst of the previous period to February 28 of the following year. Pearson correlation coefficients were used for path analysis, GF and DGF as basic variables. For CR, GV and GF the highest average occurred in 2009/10 period. The genotypes ‘BRS Kampai’ and ‘BRS Libra’ highest CR. They are considered stable and adapted as the CR genotypes ‘Casc. 967’ and ‘BRS Kampai’. There was negative correlation between CR and GV for Σh <20 ° C, Σh> 30 °C and Σh with URA <50% and positive correlation between these variables and Σh 25-30 °C and Σh with URA> 70%. The evaluation of GV ‘Cons. 681’ and ‘Casc. 1055’ can be considered adapted and stable. The lowest average was presented by the genotype ‘Sta. Áurea’ though the genotype is also stable. In GF evaluation genotypes are considered adapted ‘BRS Bonão’, ‘Casc. 1055’, ‘Cons. 681’ with adaptability to all evaluated period. In path analysis was direct effect Σh 25-30 °C on flower bud density. In evaluating DGV and DGF and the variations are due to genetic effect. The most adapted and stable genotypes for DGV were ‘T. Beauty’, ‘T. Snow’, ‘Casc. 1055’ and ‘Cons. 681’. CR and GV variables are strongly affected by environment. GF is strongly affected by genetic conditions and moderately affected by environment. DGV and DGF are affected basically by genetic conditions.
