Raptors are usually considered to be mainly visually dependent, and the use of other sensory modalities has rarely been studied in these birds. Here, we investigated experimentally which senses (vision and/or olfaction) Turkey vultures (Cathartes aura) and Southern caracaras (Caracara plancus) use to find hidden food. First, two identical stainless-steel perforated balls, one containing a putrefie
Management decisions in conservation of threatened species require trading off social needs against biodiversity values, including the prioritization of conservation locations, i.e. where conservation efforts should take place. To improve conservation decisions for the thick-shelled river mussel, Unio crassus, a highly threatened temporary parasite on fish, we performed a field study on how mussel
Pituitary adenylate cyclase activating polypeptide-38 (PACAP38) is a widely distributed neuropeptide involved in neuroprotection, neurodevelopment, nociception and inflammation. Moreover, PACAP38 is a potent inducer of migraine-like attacks, but the mechanism behind this has not been fully elucidated.Migraine is a neurovascular disorder, recognized as the second most disabling disease. Nevertheles
In genotype-based recall (GBR) studies, people (or their biological samples) who carry genotypes of special interest for a given hypothesis test are recalled from a larger cohort (or biobank) for more detailed investigations. There are several GBR study designs that offer a range of powerful options to elucidate (1) genotype-phenotype associations (by increasing the efficiency of genetic associati
Little is known on whether the effects of marriage education programs such as the Prevention and Relationship Enhancement Program (PREP) hold across genders or are moderated by risk factors (participants’ parents’ relationship instability, participants’ low level of education, being unmarried, previous relationship counseling, who initiated program participation, having many children). This trial
Objectives the aim of this study was to adapt the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into six European cultures and validate it as a common measure of quality of life in systemic sclerosis (SSc). Methods this was a seven-country (Germany, France, Italy, Poland, Spain, Sweden and UK) cross-sectional study. A forward–backward translation process was used to adapt the English S
The understanding of health inequalities requires further development of epidemiological capacity and must have a broad focus on social determinants of health The article by Agardh et al (1) in this issue of Läkartidningen compares the trend of population health in Stockholm county versus the rest of the country. The article represents an important attempt to monitor and understand the driving for
Correct electrode placement - a prerequisite for correct ECG interpretation Different lead misplacements may present with typical ECG changes, which may influence the management of the patient, if not identified and corrected. It is important, both for the ECG technician and for the interpreting physician, to recognize typical patterns of lead misplacement to avoid misinterpretation of the ECG.
Good outcomes when emergency physicians diagnosed deep vein thrombosis Deep vein thrombosis of the lower limb is best diagnosed with ultrasound. Internationally, several studies have shown promising and often equal results when emergency physicians have been compared with radiologists in diagnosing thrombosis. Our results confirm these findings in a non-academic hospital and for the first time in
Background: After root canal treatment, a choice is made between different coronal restorations which in the long run could affect the survival of the tooth. Objective: To compare demographic characteristics between individuals choosing an indirect coronal restoration (crown, inlay/onlay) and individuals choosing other restorations after completion of a root filling. Methods: The cohort consisted
Introduction: The reported rate of nonunion of distal femoral fractures varies in the literature. Several risk factors for nonunion following lateral locked plating (LLP) have been described. We aimed to study the rate of nonunion, and risk factors thereof, in a Swedish population where fragility fractures are common. A secondary aim was to study risk factors for reoperation for any cause. Patient
Introduction: To reduce local recurrence rates when performing anterior resection in rectal cancer surgery Swedish national guidelines recommend rectal washout. This study aimed to describe current Swedish practice of rectal washout. Methods: Questionnaires were sent to Swedish surgical departments performing rectal cancer surgery. Results: Thirty-five units performed open rectal cancer surgery, a
Introduction: The hospitalization rate of paroxysmal supraventricular tachycardia (PSVT) in a nationwide study is not established. We determined age- and sex-specific hospitalization rates and time trends for hospitalized PSVT in the Swedish population between 1987 and 2010. Methods: This nationwide study is based on the Swedish Hospital Discharge Register. The patients with first PSVT diagnoses b
Personer som bryr sig om vad andra tycker om dem håller sig borta från diskussioner om politik i sociala medier, trots att de är intresserade av politik. Politiska diskussioner i sociala medier och webbaserade paneler kan därför vara en snedvriden avbild av vad människor i allmänhet egentligen tycker och tänker, skriver forskare med utgångspunkt i en ny studie.
Purpose: This paper aims to discuss additive manufacturing (AM) in the context of applications for musical instruments. It examines the main AM technologies used in musical instruments, goes through a history of musical applications of AM and raises the questions about the application of AM to create completely new wind instruments that would be impossible to produce with conventional manufacturin
Introduction: Traditional validation of umbilical cord blood samples with positive veno-arterial ΔpH and arterio-venous ΔpCO2 values confirms the source of samples, whereas negative Δvalues represent mix-up of samples. To investigate whether this is true, the distributions of V-A ΔpO2 and A-V Δlactate were also explored and related to clinical characteristics. In addition, different cord blood sam
