Multi-level multi-modality (PET and CT) fusion radiomics: Prognostic modeling for non-small cell lung carcinoma.

Phys Med Biol 2021 Sep 20. Epub 2021 Sep 20.

Division of Nuclear Medicine, University Hospital of Geneva, 24 Rue Micheli-du-Crest, 1211 Geneva 4, Geneva, SWITZERLAND.

We developed multi-modality radiomic models by integrating information extracted from 18F-FDG PET and CT images using feature- and image-level fusions, toward improved prognosis for non-small cell lung carcinoma (NSCLC) patients. Two independent cohorts of NSCLC patients from two institutions (87 and 95 patients) were cycled as training and testing datasets. Fusion approaches were applied at two levels, namely feature- and image-levels. Read More

RMplex: An efficient method for analyzing 30 Y-STRs with high mutation rates.

Forensic Sci Int Genet 2021 Sep 11;55:102595. Epub 2021 Sep 11.

Department of Genetic Identification, Erasmus MC, University Medical Center Rotterdam, Rotterdam, the Netherlands. Electronic address:

Y-chromosomal short tandem repeats (Y-STRs) with high mutation rates are recognized as valuable genetic markers for differentiating paternally related men, who typically cannot be separated with standard Y-STRs, and were shown to provide paternal lineage differentiation on a higher resolution level than standard Y-STRs. Both features make Y-STRs with high mutation rates relevant in criminal casework, particularly in sexual assault cases involving highly unbalanced male-female DNA mixtures that often fail autosomal forensic STR profiling for the male donor. Previously, the number of known Y-STRs with mutation rates higher than 10 per locus per generation termed rapidly mutating Y-STRs (RM Y-STRs) was limited to 13, which has recently been overcome by the discovery and characterization of 12 additional RM Y-STRs.

J Am Geriatr Soc 2021 Sep 20. Epub 2021 Sep 20.

Center for the Study of Healthcare Innovation, Implementation, and Policy, VA Greater Los Angeles Healthcare System, Los Angeles, California, USA.

PLoS One 2021 20;16(9):e0257560. Epub 2021 Sep 20.

PATH, Seattle, Washington, United States of America.

Certain clinical indications and treatments such as the use of rasburicase in cancer therapy and 8-aminoquinolines for Plasmodium vivax malaria treatment would benefit from a point-of-care test for glucose-6-phosphate dehydrogenase (G6PD) deficiency. Three studies were conducted to evaluate the performance of one such test: the STANDARD™ G6PD Test (SD BIOSENSOR, South Korea). First, biological interference on the test performance was evaluated in specimens with common blood disorders, including high white blood cell (WBC) counts. Read More

A review of the toxicology of oil in vertebrates: what we have learned following the oil spill.

J Toxicol Environ Health B Crit Rev 2021 Sep 19:1-40. Epub 2021 Sep 19.

Sea Mammal Research Unit, Scottish Oceans Institute, University of St Andrews, St Andrews, UK.

In the wake of the (DWH) oil spill, a number of government agencies, academic institutions, consultants, and nonprofit organizations conducted lab- and field-based research to understand the toxic effects of the oil. Lab testing was performed with a variety of fish, birds, turtles, and vertebrate cell lines (as well as invertebrates); field biologists conducted observations on fish, birds, turtles, and marine mammals; and epidemiologists carried out observational studies in humans. Eight years after the spill, scientists and resource managers held a workshop to summarize the similarities and differences in the effects of DWH oil on vertebrate taxa and to identify remaining gaps in our understanding of oil toxicity in wildlife and humans, building upon the cross-taxonomic synthesis initiated during the Natural Resource Damage Assessment.

Mechanical Stimulation Muscle Activity Is Necessary for the Maturation of Tendon Multiscale Mechanics During Embryonic Development.

Front Cell Dev Biol 2021 3;9:725563. Epub 2021 Sep 3.

Department of Biomedical Engineering, Pennsylvania State University, University Park, PA, United States.

During embryonic development, tendons transform into a hypocellular tissue with robust tensile load-bearing capabilities. Previous work suggests that this mechanical transformation is due to increases in collagen fibril length and is dependent on mechanical stimulation muscle activity. However, the relationship between changes in the microscale tissue structure and changes in macroscale tendon mechanics is still unclear. Read More

Olmesartan-Induced Enteropathy: A Report of an Unusual Cause of Chronic Diarrhea.

Cureus 2021 Aug 8;13(8):e17004. Epub 2021 Aug 8.

Gastroenterology Department, General University Hospital of Patras, Patras, GRC.

Olmesartan, an angiotensin II receptor blocker indicated in the treatment of hypertension, has been associ-ated with a seronegative sprue-like enteropathy that should be considered in the differential diagnosis of patients with unexplained chronic diarrhoea. It typically presents with severe chronic diarrhoea, considerable weight loss, and villous atrophy on biopsy and may be difficult to recognize because of its clinical and histological similarities to other clinical entities. Practically, discontinuation of the drug leads to dramatic recovery of the symptoms. Read More
