Prediction of breast cancer molecular subtypes using DCE-MRI based on CNNs combined with ensemble learning.

Phys Med Biol 2021 Jul 30. Epub 2021 Jul 30.

Institute of Medical Imaging Engineering, Shanghai University of Science and Technology, Shanghai 200093, Shanghai, CHINA.

To design an ensemble learning based prediction model using different breast DCE-MR post-contrast sequence images to distinguish two kinds of breast cancer subtypes (luminal and non-luminal). We retrospectively studied preoperative DCE-MRIs and molecular information of 266 breast cancer cases with either luminal subtype (luminal A and luminal B) or non-luminal subtype (human epidermal growth factor receptor 2 and triple negative). Then, multiple bounding boxes covering tumor lesions were acquired from three series of post-contrast DCE-MR sequence images which were determined by radiologists. Read More

Multi-model and multi-slice ensemble learning architecture based on 2D convolutional neural networks for Alzheimer's disease diagnosis.

Comput Biol Med 2021 Jul 22;136:104678. Epub 2021 Jul 22.

Intelligent Physiological Measurement and Clinical Translation, Beijing International Platform for Scientific and Technological Cooperation, Department of Biomedical Engineering, Faculty of Environment and Life Sciences, Beijing University of Technology, Beijing, 100124, China.

Alzheimer's Disease (AD) is a chronic neurodegenerative disease without effective medications or supplemental treatments. Thus, predicting AD progression is crucial for clinical practice and medical research. Due to limited neuroimaging data, two-dimensional convolutional neural networks (2D CNNs) have been commonly adopted to differentiate among cognitively normal subjects (CN), people with mild cognitive impairment (MCI), and AD patients.

[Neurological complications in haematopoietic stem cell transplant patients].

Rev Neurol 2021 Sep;73(5):174-183

Hospital de la Santa Creu i Sant Pau , Barcelona, España.

Introduction: Neurological complications are some of the most important complications that can occur in a patient undergoing haematopoietic stem cell transplantation (HSCT), not only because of the high mortality rate, but also because of the sequelae that appear in survivors. The causes of such complications are manifold and very often coexist in the same patient: toxicity of the conditioning regimen, graft-versus-host disease and its treatment, infections and their treatment, platelets and coagulation disorders, liver failure or arterial hypertension with low platelet count.

Aims: The aim of the present study is to provide a clinical description and to describe the risk factors for complications involving the central nervous system that may occur during the course of HSCT, in order to assist in the early detection of these disorders that may have a negative influence on the morbidity and mortality of these patients.

Women Health 2021 Jul 30:1-14. Epub 2021 Jul 30.

Intensive Care in Obstetric Research Group (GRICIO), Department of Obstetrics and Gynecology, University of Cartagena, Cartagena, Colombia.

Maternal near-miss (MNM) is a maternal quality care indicator. The World Health Organization (WHO) defines it as a state in which a woman nearly dies but survives due to a complication during pregnancy, birth, or puerperium. The Latin American Federation of Obstetrics and Gynecology (FLASOG) and the Colombian National Health Institute (INS) established recommendations for the event's epidemiological surveillance; nonetheless, the operational definitions of the cases are different.

J Sleep Res 2021 Jul 29:e13431. Epub 2021 Jul 29.

Department of Applied Physics, University of Eastern Finland, Kuopio, Finland.

To aim is investigate whether demographic, polysomnographic or sleep behaviour data differ between non-sleepy, sleepy and very sleepy patients with mild obstructive sleep apnea.

Acute ischemic stroke in childhood: a comprehensive review.

Eur J Pediatr 2021 Jul 29. Epub 2021 Jul 29.

Child Neurology and Infantile Psychiatry Unit, Department of Human Neuroscience, Sapienza University of Rome, Rome, Italy.

This review provides an updated analysis of the main aspects involving the diagnosis and the management of children with acute ischemic stroke. Acute ischemic stroke is an emergency of rare occurrence in children (rate of incidence of 1/3500 live birth in newborns and 1-2/100,000 per year during childhood with peaks of incidence during the perinatal period, under the age of 5 and in adolescence). The management of ischemic stroke in the paediatric age is often challenging because of pleomorphic age-dependent risk factors and aetiologies, high frequency of subtle or atypical clinical presentation, and lacking evidence-based data about acute recanalization therapies.

Congenital Aorto-Cardiac Connections (CACC) Revisited: Introduction of a Novel Anatomic-therapeutic Classification.

Pediatr Cardiol 2021 Jul 29. Epub 2021 Jul 29.

Department of Pediatric Cardiology, Children's Medical Center (Pediatric Center of Excellence), Tehran University of Medical Sciences, Tehran, Iran.

Abnormal congenital aorto-cardiac communications (CACC) are a heterogeneous constellation of anomalies that provide an abnormal connection between the aorta and other cardiac chambers or structures, including the atria, ventricles, the main pulmonary artery, and the coronary sinus. The current terminology of CACC has significant errors and shortcomings including inconsistent and interchangeable use of terms of fistula and tunnel and lack of an inclusive classification with practical information on therapeutic management. The aims of this study were threefold: firstly, to perform a concise narrative review of congenital pathologic connections between the aortic root and cardiac chambers which include rupture of congenital sinus of Valsalva aneurysm, aorto-left ventricular and less commonly right ventricular tunnels, coronary cameral fistulas, and aorto-atrial communications; secondly, to investigate the differentiating features of the so-called aorta right atrial tunnel (ARAT), with and without coronary artery take-off from the tunnel, and coronary cameral fistula (CCF) by applying a differential diagnostic assistance toolbox to two groups of patients with ARAT and CCF; and lastly, to propose a practical and inclusive anatomic-therapeutic classification for CACCs.

Integrative analysis of genomic variants reveals new associations of candidate haploinsufficient genes with congenital heart disease.

PLoS Genet 2021 Jul 29;17(7):e1009679. Epub 2021 Jul 29.

Department of Internal Medicine, McGovern Medical School, University of Texas Health Science Center at Houston, Houston, Texas, United States of America.

Numerous genetic studies have established a role for rare genomic variants in Congenital Heart Disease (CHD) at the copy number variation (CNV) and de novo variant (DNV) level. To identify novel haploinsufficient CHD disease genes, we performed an integrative analysis of CNVs and DNVs identified in probands with CHD including cases with sporadic thoracic aortic aneurysm. We assembled CNV data from 7,958 cases and 14,082 controls and performed a gene-wise analysis of the burden of rare genomic deletions in cases versus controls. Read More

Sarcopenia versus cancer cachexia: the muscle wasting continuum in healthy and diseased aging.

Biogerontology 2021 Jul 29. Epub 2021 Jul 29.

CIAFEL, Faculty of Sport, University of Porto, Dr. Plácido da Costa 91, 4200-450, Porto, Portugal.

Muscle wasting is one of the major health problems in older adults and is traditionally associated to sarcopenia. Nonetheless, muscle loss may also occur in older adults in the presence of cancer, and in this case, it is associated to cancer cachexia. The clinical management of these conditions is a challenge due to, at least in part, the difficulties in their differential diagnosis. Read More
