Introduction The pathogenesis of cold urticaria (ColdU) and cold-induced anaphylaxis (ColdA) remains poorly understood, and ColdA is underrepresented in anaphylaxis literature. Laboratory features to guide management are largely unknown. This study evaluated basal serum tryptase (BST) and total immunoglobulin E (IgE) levels in ColdU and ColdA, thei...

Objectives Modern obstetrics confronts a rise in caesarean sections (CS). Prevention of unnecessary primary CS is a global priority. Women face intense psychological and physiological challenges during childbirth. Fear and anxiety during labour reduce women’s self-confidence and empowerment. Yoga is a body-mind practice that lowers maternal fear an...

This paper discusses the implementation and usage of a gyroid cell in topology optimization of load-carrying structural parts. Conventional topology optimization relies on a linear elastic model and the strain energy density field of the structure in order to optimally distribute the material within a given domain. This procedure may take place eit...

We recently reported enhanced parasympathetic activation at rest throughout pregnancy associated with regular yoga practice. The present study presents a secondary analysis of data collected within a prospective cohort study of 33 pregnant women practicing yoga once weekly throughout pregnancy and 36 controls not involved in formal pregnancy exerci...

The increasing number of caesarean section (CS) is a major challenge in modern obstetrics. This rise is not supported by better neonatal and maternal outcomes. The prevention of unnecessary primary CS is a global priority. This study focuses on effectiveness and safety of yoga practice during pregnancy and it’s connection to perinatal outcome. We c...

Background: The European baseline series (EBS) of contact allergens is subject to change. An allergen is considered for inclusion in the EBS when routine patch testing of patients with suspected contact dermatitis results in at least 0.5% prevalence rate. We aimed to determine the frequency of sensitizations to 40 allergens and the usefulness of la...

Design of lightweight load-carrying structural parts is becoming increasingly demanding due to ever-tighter requirements on structural weight, performance, and durability. Topology optimization is the most recent and most promising tool supporting the development of such high-performance load-carrying parts – at least in theory. In practical applic...

Intramuscular adrenaline is the first-line treatment for anaphylaxis and an adrenaline autoinjector (AAI) should be carried as a first-aid measure by patients at risk. Cold-induced anaphylaxis (ColdA), which may result in fatality, is common in typical cold urticaria (ColdU), and risk factors for ColdA have recently been identified for the first ti...

Background We studied the effect of crystalloid co-loading with simultaneous infusion of vasopressor phenylephrine on circulatory stability during general anaesthesia induction with propofol in ASA II/III patients. We analysed the postinduction phase because circulatory instability is most prevalent in this period and more prominent in multimorbid...

Background Cold urticaria (ColdU), that is, the occurrence of wheals or angioedema in response to cold exposure, is classified into typical and atypical forms. The diagnosis of typical ColdU relies on whealing in response to local cold stimulation testing (CST). It can also manifest with cold‐induced anaphylaxis (ColdA). We aimed to determine risk...

Background: Teaching using paper problem-based learning (p-PBL) sessions has left some students fatigued with the learning process. Therefore, attempts have been made to replace p-PBL with digitally enhanced, decision-making PBL in the form of virtual patients (VPs). Student enthusiasm for substituting p-PBL with VPs has not been quantitatively ev...

Chronic diseases, especially diabetes mellitus, are huge public health burden. Therefore, new health care models for sharing the responsibility for care among health care providers and patients themselves are needed. The concept of empowerment promotes patient’s active involvement and control over their own health. It can be achieved through educat...

Theoretical background: Virtual patients have been in use as an add on educational methods to traditional methods for some time. Through multimedia and interactive elements along with the virtual simulation of the clinical work with patients, medical students get an insight into the numerous forms of artificially created substitutes for real patien...

Literature-based discovery (LBD) generates discoveries, or hypotheses, by combining what is already known in the literature. Potential discoveries have the form of relations between biomedical concepts; for example, a drug may be determined to treat a disease other than the one for which it was intended. LBD views the knowledge in a domain as a net...

In natural science education it is important that the macroscopic, submicroscopic and symbolic levels are interconnected in a student’s mind. Primary school children have the greatest difficulty in understanding the sub-microscopic, which is outside their experiential framework. This research examines the classroom application of the virtual labora...

Background The proliferation of the scientific literature in the field of biomedicine makes it difficult to keep abreast of current knowledge, even for domain experts.
