Artificial Intelligence-based Assessment of Prostate Cancer Metastases in PET/CT

Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. The evaluation of medical images including PET/CT is challeng

Systemic chemotherapy with or without hepatic arterial infusion chemotherapy for liver metastases from pancreatic cancer: a propensity score matching analysis

The significance of systemic chemotherapy (SCT) combined with hepatic arterial infusion (HAI) chemotherapy in the treatment of pancreatic ductal adenocarcinoma with liver metastases (PACLM) remains unclear. Based on previous studies, this single-center propensity score matching (PSM) study aimed to explore the efficacy of SCT with or without HAI for PACLM.

Arterial oxygen desaturation during apnea in humans

We studied the effect of the human diving response, defined as bradycardia and reduced peripheral blood flow, on arterial hemoglobin desaturation. We induced a diving response of different magnitudes by using apnea in air and apnea with face immersion. Each of 21 subjects performed five apneas in air and five apneas with face immersion in 10 degrees C water. Periods of apnea in both conditions wer

Diving response and apneic time in humans

The aim of this study was to compare apneic time with the human diving response, defined as heart rate (HR) reduction and reduced skin blood flow, in groups with varying degrees of breath-hold diving experience. Apneic time and HR reduction at apneas in air and apneas with face immersion in cold water were thus recorded in nine groups. Skin capillary blood flow was recorded in six of the groups. A

Effects of lung volume and involuntary breathing movements on the human diving response

The effects of lung volume and involuntary breathing movements on the human diving response were studied in 17 breath-hold divers. Each subject performed maximal effort apnoeas and simulated dives by apnoea and cold water face immersion, at lung volumes of 60%, 85%, and 100% of prone vital capacity (VC). Time of apnoea, blood pressure, heart rate, skin capillary blood flow, and fractions of end-ex

Effects of repeated apneas on apneic time and diving response in non-divers

Human breath-hold divers usually perform a series of dives with short intervals. Repeated apneas prolong apneic time, and an accentuated diving response has been suggested to be the cause. The aim of this study was to investigate the effect of repeated apneas on apneic time and diving response in humans. Forty-one subjects performed a series of five apneas with face immersion in water of 10 degree

Universal Design for Learning (UDL) in Higher Education: A Case Study in LTH

Universal Design for Learning (UDL) is considered an approach to include all students in the university. UDL is based on three main principles providing multiple means of Engagement, multiple means of representation, and multiple means of action and expression. It is relevant for teachers and departments to focus on more flexibility for students to get the required information, expressing their th

Building study-related relationships : How student relationships and readiness affect academic outcome in higher education

The present dissertation explores students’ perception of their own readiness for higher education and students’ study related relations and the effect on academic outcome. The complexity of student engagement and academic success means that it is relevant to conduct in-depth studies of particular student populations, to explore how certain factors play out in that specific context. First, student

Joint management of marine mammals and a fish species: The case of cod and grey seals in the Nordic-Baltic Sea countries

In this paper, we present a simple theoretical, steady-state equilibrium, predator-prey model for the joint management of marine mammals and a fish species. As an empirical case, we choose cod and grey seals in the Nordic-Baltic Sea countries, and several benefits and costs related to the latter are considered. We show that the optimal grey seal population is much lower than the actual population,

This article presents the main results of the author’s doctoral research (Ruiz Carreras, 2021), with a general goal to study the discourse of the pressure groups of the European Dairy Industry (EDI) from a non-speciesist perspective. To do so, the EDI is examined as an economic and influential actor, identifying the companies and key pressure groups, and analyzing the discourse constructed regardi

Point prevalence of SARS-CoV-2 infection in Sweden at six time points during 2020

BackgroundIn order to estimate the prevalence and understand the spread of SARS-CoV-2 in Sweden, the Public Health Agency of Sweden, with support from the Swedish Armed Forces, conducted a series of point prevalence surveys between March and December 2020.MethodsSampling material and instructions on how to perform self-sampling of the upper respiratory tract were delivered to the homes of the part

The impact of “To Err Is Human” on patient safety in anesthesiology. A bibliometric analysis of 20 years of research

Background: Patient safety gained public notoriety following the 1999 report of the Institute of Medicine: To Err is Human – Building a Safer Health System which summarized a culminated decades' worth of research that had so far been largely ignored. The aim of this study was to analyze the report's impact on patient safety research in anesthesiology.Methods: A bibliometric analysis was performed

The general objective of this research is to study the discourse of the European Dairy Industry (EDI) lobbyists from a non speciesist perspective. To achieve this, the EDI was examined as an economic and influential actor, through a political economy analysis, in order to identify the main companies and pressure groups, their links and their numbers. Then the discourse that the interest groups con

Equine-assisted intervention to improve perceived value of everyday occupations and quality of life in people with lifelong neurological disorders : A prospective controlled study

People with neurological disorders suffer from poor mobility, poor balance, fatigue, isolation and monotonous everyday activities. Studies show that equine-assisted interventions can improve their mobility and balance, but could these kinds of interventions also increase participants’ activity repertoire and self-assessed health, and reduce their fatigue? The study was conducted as a prospective,
