A Statistical DOI Estimation Algorithm for a SiPM-Based Clinical SPECT Insert

A prototype clinical brain SPECT insert has been designed for use in simultaneous SPECT/MRI. The system utilises novel slit-slat collimators which, like pinhole collimators, suffers from parallax errors due to the large incident angle of photons. A statistical algorithm has been developed to determine the depth-of-interaction (DOI) with a view to improving image performance. The importance of DOI

Epidemiology and Prognostic Factors in Acute Lower Limb Ischaemia : A Population Based Study

Objective: The aim of this study was to evaluate the contemporary population based incidence of acute lower limb ischaemia (ALI) and factors associated with major amputation/death at one year. Methods: In this retrospective observational study, in hospital, operation, radiological, and autopsy registries were scrutinised to capture 161 citizens of Malmö, Sweden, with ALI between 2015 and 2018. Age

Robot-assisted versus conventional laparoscopic adrenalectomy : Results from the EUROCRINE Surgical Registry

Background: Adrenalectomy is routinely performed via the minimally invasive approach. Safety of adrenalectomy using the robot-assisted technique has been widely demonstrated by several series, but the literature is scarce regarding the comparison of conventional laparoscopic versus robot-assisted approach. We decided to carry out a multicenter study to compare clinical and surgical outcomes betwee

A suggestion for the quantification of precise and bounded probability to quantify epistemic uncertainty in scientific assessments

An honest communication of uncertainty about quantities of interest enhances transparency in scientific assessments. To support this communication, risk assessors should choose appropriate ways to evaluate and characterize epistemic uncertainty. A full treatment of uncertainty requires methods that distinguish aleatory from epistemic uncertainty. Quantitative expressions for epistemic uncertainty

Institutional trust and emergency preparedness : Perceptions of Covid 19 crisis management in Sweden

The Covid 19 pandemic has put the issue of public trust at the centre of political analysis. This article inquires into the level of public trust in Sweden concerning current crisis management as well as preparedness for future crises. The empirical basis for this study consists of unique data generated through two surveys on the Covid 19 virus conducted during 2020 in Sweden. Respondents were ask

Clinical outcome and adherence rate in Scandinavian patients with intermediate-intensity prophylaxis before and after the switch of standard half-life FVIII products to BAY 81–8973

Introduction: Treatment optimization in haemophilia A can be achieved by choice of FVIII product and knowledge of pharmacokinetics (PK), phenotype and adherence. A favourable PK profile of BAY 81–8973 (octocog alfa) (Kovaltry, Bayer AB) compared to other standard half-life (SHL) FVIII products has been suggested. Aim: To evaluate whether the switch to BAY 81–8973, using the same dosing schedule, i

Prospective evaluation of 92 serum protein biomarkers for early detection of ovarian cancer

Background: CA125 is the best available yet insufficiently sensitive biomarker for early detection of ovarian cancer. There is a need to identify novel biomarkers, which individually or in combination with CA125 can achieve adequate sensitivity and specificity for the detection of earlier-stage ovarian cancer. Methods: In the European Prospective Investigation into Cancer and Nutrition (EPIC) coho

Dynamic Standing Exercise in a Novel Assistive Device Compared with Standard Care for Children with Cerebral Palsy Who Are Non-Ambulant, with Regard to Quality of Life and Cost-Effectiveness

Children with cerebral palsy who are non-ambulant cannot stand or walk independently. In Sweden, daily static standing is part of standard care for these children even though it is time-consuming and costly, and while it may benefit the well-being of many children, it is inconvenient for others. A novel stander enables dynamic standing through walking movements. The aim of this study was to compar

Supporting Entrepreneurship and Innovation in Higher Education in Lithuania

Changes in climate, technology and demography as well as the COVID-19 pandemic are transforming our societies and way of life. The EU Member States, as elsewhere, need a strong higher education sector, as an engine of innovation and entrepreneurship and driver of skills and knowledge. As the conditions in which our societies operate are changing, there is broad consensus that higher education inst

Dissolved neodymium isotopes in the Mediterranean Sea

The neodymium isotopic composition (εNd) of seawater is one of the most important geochemical tracers to investigate water mass provenance, which can also serve as a proxy to reconstruct past variations in ocean circulation. Nd isotopes have recently also been used to reconstruct past circulation changes in the Mediterranean Sea on different time scales. However, the modern seawater εNd dataset fo

Magnetic resonance imaging of the brachial plexus. Part 2 : Traumatic injuries

The most common indications for magnetic resonance imaging (MRI) of the brachial plexus (BP) are traumatic injuries. The role of MRI of the BP has increased because of recent trends favoring earlier surgery. Determining preganglionic vs. postganglionic injury is essential, as different treatment strategies are required. Thus, MRI of the BP should be supplemented with cervical spine MRI to assess t

Establishing metastatic prostate cancer quality indicators using a modified Delphi approach

Background: There is variation in the care provided to men with metastatic prostate cancer (mPCa). There has been no previous set of quality indicators (QIs) regarding the management of men with mPCa. The objective of this study is to develop a set of international mPCa-specific QIs, which will enable global benchmarking of quality of care. Materials and methods: Potential QIs were identified thro

Personalized seizure signature : An interpretable approach to false alarm reduction for long-term epileptic seizure detection

Objective: Long-term automatic detection of focal seizures remains one of the major challenges in epilepsy due to the unacceptably high number of false alarms from state-of-the-art methods. Our aim was to investigate to what extent a new patient-specific approach based on similarly occurring morphological electroencephalographic (EEG) signal patterns could be used to distinguish seizures from nons

Assessing How Consumers Interpret and Act on Results from At-Home COVID-19 Self-test Kits : A Randomized Clinical Trial

Importance: The US Food and Drug Administration (FDA) authorized SARS-CoV-2 rapid at-home self-test kits for individuals with and without symptoms. How appropriately users interpret and act on the results of at-home COVID-19 self-tests is unknown. Objective: To assess how users of at-home COVID-19 self-test kits interpret and act on results when given instructions authorized by the FDA, instructio
