Prediction of obstructive coronary artery disease from myocardial perfusion scintigraphy using deep neural networks

For diagnosis and risk assessment in patients with stable ischemic heart disease, myocardial perfusion scintigraphy is one of the most common cardiological examinations performed today. There are however many motivations for why an artificial intelligence algorithm would provide useful input to this task. For example to reduce the subjectiveness and save time for the nuclear medicine physicians wo

Cerebrospinal Fluid Biomarker Levels as Markers for Nursing Home Placement and Survival Time in Alzheimer's Disease

BACKGROUND: Cerebrospinal fluid (CSF) biomarkers are associated with conversion from mild cognitive impairment to Alzheimer's disease (AD), but their predictive value for later end-points has been less evaluated with inconsistent results.OBJECTIVE: We investigated potential relationships between CSF amyloid-β1-42 (Aβ42), phosphorylated tau (P-tau), and total tau (T-tau) with time to nursing home p

Differences in Dementia Care Between Swedish-Born and Foreign-Born from Countries with Different Country Level Socioeconomic Position : A Nationwide Register-Based Study

BACKGROUND: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages.OBJECTIVE: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focu

Living Conditions and Social Outcomes in Adults With Cerebral Palsy

Objectives: To analyse the living conditions and social outcomes (housing, engagement in employment or higher education, access to personal assistance and having a partner) in adults with cerebral palsy (CP) relative to their age, sex, communication ability, and motor skills. Methods: Cross-sectional registry-based study of 1,888 adults (1,030 males/858 females) with CP in the Swedish CP follow-up

Psychiatric Comorbidity and Economic Hardship as Risk Factors for Intentional Self-Harm in Gambling Disorder—A Nationwide Register Study

Background: There is an increased risk of suicidality in gambling disorder (GD) and economic hardship is common in the population. Economic hardship itself is a risk factor for suicidality. This study aims to explore the risk of intentional self-harm in GD utilizing social welfare payment (SWP) as a proxy for economic hardship and exploring how economic hardship, gender, criminality, socioeconomic

Exclusive underexpression of vitamin D receptor exon 1f transcripts in tumors of primary hyperparathyroidism

OBJECTIVE: Primary hyperparathyroidism (pHPT) is characterized by excessive production of parathyroid hormone (PTH) due to parathyroid adenomas while uremic secondary HPT (sHPT) is caused by parathyroid hyperplasia in response to renal failure. Active vitamin D, 1,25-dihydroxyvitamin D(3) (1,25-(OH)(2)D(3)), with the vitamin D receptor (VDR) is involved in regulation of the calcium homeostasis tog

Multiple endocrine neoplasia type 1 polymorphism D418D is associated with sporadic primary hyperparathyroidism

BACKGROUND: Sporadic primary hyperparathyroidism (pHPT) occurs separately and in several hereditary disorders including multiple endocrine neoplasia type 1. Irradiation to the neck, female gender, and age are well-identified risk factors that predispose to pHPT. The multiple endocrine neoplasia type 1 gene is the most commonly deranged gene in parathyroid adenomas and contains several polymorphism

Underexpression of Gcm2, a master regulatory gene of parathyroid gland development, in adenomas of primary hyperparathyroidism

OBJECTIVE: Glial cells missing (Gcm) was first identified as a binary switch between neuronal and glial determination in Drosophila. Two homologues of Drosophila Gcm have been identified in mice and humans, namely Gcm1 and Gcm2. Mouse Gcm2 is restricted to parathyroid tissues and Gcm2 was recently identified as a master regulatory gene of parathyroid gland development as Gcm2 knockout mice lack pa

Intragenic allelic loss and promoter hypermethylation of the RIZ1 tumor suppressor gene in parathyroid tumors and pheochromocytomas

BACKGROUND: Loss of heterozygosity (LOH) at chromosome 1p is a common abnormality in both parathyroid tumors and pheochromocytomas. The recently characterized tumor suppressor gene RIZ1, located at 1p36, has emerged as a putative candidate to be involved in endocrine tumorigenesis.MATERIAL: Presence of allelic loss, promoter hypermethylation, and mutational aberrations of the RIZ1 gene were invest

A versatile organisation : Mapping the military's core roles in a changing security environment

What roles are military institutions expected to play in today's rapidly changing security environment? How are they supposed to interact with the society they are tasked to protect? These questions have been posed by classical military sociologists as well as by a newer generation of scholars. Yet so far, a comprehensive mapping of the military's potential roles in contemporary society is missing

A side-channel attack on a masked IND-CCA secure saber KEM implementation

In this paper, we present a side-channel attack on a first-order masked implementation of IND-CCA secure Saber KEM. We show how to recover both the session key and the long-term secret key from 24 traces using a deep neural network created at the profiling stage. The proposed message recovery approach learns a higher-order model directly, without explicitly extracting random masks at each executio

25-hydroxyvitamin D(3)-1alpha-hydroxylase expression in normal and pathological parathyroid glands

Active vitamin D, 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)], plays a pivotal role in calcium homeostasis and bone metabolism. Circulating levels of 1,25(OH)(2)D(3) are thought to be dependent mainly on the activity of the renal cytochrome P450 enzyme 25-hydroxyvitamin D(3)-1alpha-hydroxylase (1alpha-hydroxylase), which is potently induced by PTH. However, 1alpha-hydroxylase activity or expressi

Allelic loss in clinically and screening-detected primary hyperparathyroidism

OBJECTIVE: Parathyroid adenomas frequently harbour deletions of genomic DNA at chromosome regions 1p, 6q and 11q. In this study we related clinical characteristics in 56 patients with primary hyperparathyroidism (pHPT) to loss of heterozygosity (LOH) in these chromosome regions.DESIGN: LOH analysis was performed on 56 sporadic parathyroid tumours using a total of 18 microsatellite markers for chro

c-Abl kinase regulates neutrophil extracellular trap formation and lung injury in abdominal sepsis

Sepsis is associated with exaggerated neutrophil responses although mechanisms remain elusive. The aim of this study was to investigate the role of c-Abelson (c-Abl) kinase in neutrophil extracellular trap (NET) formation and inflammation in septic lung injury. Abdominal sepsis was induced by cecal ligation and puncture (CLP). NETs were detected by electron microscopy in the lung and by confocal m

Health-Care and Societal Costs Associated with Non-Persistence with Subcutaneous TNF-α Inhibitors in the Treatment of Inflammatory Arthritis (IA) : A Retrospective Observational Study

Objective: A few studies have suggested that patients with inflammatory arthritis (IA) who remain persistent with subcutaneous TNF-α inhibitors (SC-TNFi) incur lower health care costs than patients who discontinue treatment, whereas data on the impact of non-persistence on indirect costs are largely lacking. Furthermore, existing estimates are based on fixed follow-ups, in relation to treatment in

High PGD2 receptor 2 levels are associated with poor prognosis in colorectal cancer patients and induce VEGF expression in colon cancer cells and migration in a zebrafish xenograft model

Background: Despite intense research, the prognosis for patients with advanced colorectal cancer (CRC) remains poor. The prostaglandin D2 receptors DP1 and DP2 are explored here as potential therapeutic targets for advanced CRC. Methods: A CRC cohort was analysed to determine whether DP1 and DP2 receptor expression correlates with patient survival. Four colon cancer cell lines and a zebrafish meta
