Gender Differences in Vascular Interventions for Lower Limb Ischaemia

AbstractObjectives to investigate changes in intervention for lower limb ischaemia with regard to gender. Material and method type of procedure, the age and gender of all patients (8687) undergoing interventions (12 295) for lower limb ischaemia in Stockholm 1970–1994, were obtained from the National Board of Health and Welfare.Results interventions rose from 18 per million inhabitants in 1970 to 786 in 1994. The proportion of women treated grew from 34% to 48%. The number of embolectomies decreased from 80 to 69 per million. Infrainguinal reconstructions increased most from 38 in 1980–1984 to 186 per million inhabitants in 1990–1994, with the proportion of women increasing from 33 to 43%. Mean age increased from 63 to 71 years. Conclusions there was a marked increase in the number of procedures, the proportion of female patients and mean age

Microgastrinae (Hymenoptera: Braconidae) parasitizing Epirrita autumnata (Lepidoptera: Geometridae) larvae in Fennoscandia with description of Cotesia autumnatae Shaw, sp. n.

The microgastrine subset of hymenopteran parasitoids of the geometrid Epirrita autumnata is investigated in Fennoscandia. Ecology, including population dynamics, of the moth has been intensively studied in northern and mountainous Finland, Norway and Sweden. Recently supported hypotheses about the causes of its cyclic population dynamics stress the role of parasitoids, while the parasitoid complex with some 15 species is insufficiently known. The complex includes four solitarymicrogastrine species, Protapanteles anchisiades (Nixon), P. immunis (Wesmael), Cotesia salebrosa (Marshall) and C. autumnatae Shaw, sp. n. Here, we provide detailed figures for the latter, which is morphologically close to C. jucunda (Marshall), and describe the species as new to science. We also providemore general habitus figures of the other three species, as well as an identification key for the four species, aiming to aid recognition of these species by ecologists dealingwithmicrogastrine parasitoids of E. autumnata and their alternative geometrid hosts

Sexual Function in Women Suffering from Aortoiliac Occlusive Disease

AbstractObjective:to describe the sexual function in women suffering aortoiliac occlusive disease (AIOD) and in an age-matched reference group.Patients and methods:thirty-six women suffering from AIOD were included. Twenty were investigated before vascular intervention (untreated) and 16 different women after treatment (treated). Eighteen age-matched women served as areferencegroup. The patients answered a questionnaire including sexual, social and medical questions and a gynaecological examination was performed.Results:untreated patients with AIOD have a significantly impaired physical well-being compared to the other groups (p<0.001). A negative effect of the vascular disease and its treatment on sexual life was experienced by 69% oftreatedcompared to 40% affected amonguntreated(p=0.05). Vulval sensibility was impaired in 44% oftreated, 11% ofuntreatedand 22% ofreferencepatients. Defective anal sphincter function was found in 33% oftreated, 17% ofuntreatedand 6% in thereferencegroup. Those differences were not statistically significant.Conclusions:symptomatic AIOD in women is associated with a significantly impaired physical and sexual well-being. Though limited by size and methodology, the results indicate the possibility of iatrogenic nerve damage

Experience Improves the Reliability of Subjective Measurements of Temperament in Beef Cattle

Reliability of experienced and inexperienced observers when assessing the behavior of cattle when restrained in a squeeze chute (chute score), and when exiting the chute (exit score), was compared. Overall, experienced observers had higher reliability than inexperienced observers. Increasing the number of individuals scoring an animal decreased the degree of agreement. However, within an acceptable tolerance for difference in scores, such disagreement may be beneficial; it allows for subtlety in interpretations of temperament, which when averaged, may better reflect docility. Reliabilities were higher for exit score than chute score. This may reflect the complexity of the trait being evaluated, with fewer behaviors observed when cattle exit as compared to when restrained in a chute. Producers may profitably use chute and exit score to quantify docility in cattle. However, it may be worthwhile to gain experience in using the scoring system before implementing it for selection decisions

Repeated Calm Handling Can Lead to More Docile Cattle

Changes in temperament in heifers when handled either frequently or infrequently were evaluated subjectively based on their behavior when restrained in (chute score) and exiting from (exit score) a squeeze chute. Chute scores decreased over time–a favorable direction–with more dramatic declines in heifers handled more frequently. Heifers with higher chute scores on the first day of handling had the largest reduction in score. Exit scores changed less over time. Chute score therefore may be more indicative of acclimation to a novel environment than exit score. Both scores appear to offer a fast, easy and inexpensive way to quantify docility in cattle. Heifers became calmer with repeated gentle handling. Producers therefore may benefit from allowing cattle a few days to acclimate to new working facilities before assessing docility

Doping dependence of the upper critical field in untwinned YBa2Cu3O7−δ thin films

We report on measurements of the doping dependence of the upper critical field Hc,2 in 50 nm thick YBa2Cu3O7−δ films. The films are untwinned and are characterized by a small in-plane compressive strain. We find that the Hc,2 shows a strong decrease in the underdoped region of the phase diagram, in agreement with that which has been measured in relaxed single crystals. The origin of the decrease of Hc,2 in the underdoped regime is discussed within a scenario where charge density wave (CDW) order competes with superconductivity. This demonstrates the potential of using thin films to study the phase diagram of high-Tc materials under strain, and opens up the possibility for investigating the interplay between CDW order and superconductivity tuned by strain

Swedish snus and the GothiaTek® standard

Some smokeless tobacco products, such as Swedish snus, are today considered to be associated with substantially fewer health hazards than cigarettes. This risk differential has contributed to the scientific debate about the possibilities of harm reduction within the tobacco area. Although current manufacturing methods for snus build on those that were introduced more than a century ago, the low levels of unwanted substances in modern Swedish snus are largely due to improvements in production techniques and selection of raw materials in combination with several programs for quality assurance and quality control. These measures have been successively introduced during the past 30-40 years. In the late 1990s they formed the basis for a voluntary quality standard for Swedish snus named GothiaTek®. In recent years the standard has been accepted by the members of the trade organization European Smokeless Tobacco Council (ESTOC) so it has now evolved into an industrial standard for all smokeless tobacco products in Europe

Time asymmetries in extensive air showers: A novel method to identify UHECR species

Azimuthal asymmetries in signals of non-vertical showers have been observed in ground arrays of water Cherenkov detectors, like Haverah Park and the Pierre Auger Observatory. The asymmetry in time distri- butions of arriving particles offers a new possibility for the determination of the mass composition. The dependence of this asymmetry on atmospheric depth shows a clear maximum at a position that is cor- related with the primary species. In this work a novel method to determine mass composition based on these features of the ground signals is presented and a Monte Carlo study of its sensitivity is carried out.Facultad de Ciencias Exacta
