An observation‐driven state‐space model for claims size modelling

Canadian Journal of Statistics, EarlyView.
Abstract State‐space models are popular in econometrics. Recently, these models have gained some popularity in the actuarial literature. The best known state‐space models are of the Kalman‐filter type. These are called parameter‐driven because the observations do not impact the state‐space dynamics.

An Update to the Clinical Pharmacogenetics Implementation Consortium (CPIC) SLCO1B1 Allele Functionality Table Leveraging Evidence from Participants of Predominantly Sub‐Saharan African Ancestry

Clinical Pharmacology &Therapeutics, EarlyView.
The Clinical Pharmacogenetics Implementation Consortium (CPIC) has formally updated the SLCO1B1 allele functionality table based on new evidence. Notably, the alleles studied (SLCO1B1 *9, *31, *41) are enriched in the genomes of patients historically excluded from pharmacogenomics research.

Diagnostic Value of CEUS Prompting Liver Biopsy: Histopathological Correlation of Hepatic Lesions with Ambiguous Imaging Characteristics

Diagnostics, 2020
Background: Contrast-enhanced ultrasound (CEUS) allows for dynamic analysis of vascularization patterns of unclear hepatic lesions. Our study aimed to evaluate the diagnostic performance of CEUS for further characterizing suspicious liver lesions by ...

PelviSound L—Real‐time intraoperative sonographic assessment of pelvic sentinel lymph nodes using a drop‐in probe in endometrial and cervical cancer during minimally invasive surgery: A single‐center pilot feasibility study in 20 patients

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Sentinel lymph node biopsy (SLNB) is considered an essential step in the surgical management of endometrial and cervical cancers as it has led to a reduction in the need for full pelvic lymphadenectomy. This proof‐of‐concept study aimed to evaluate the feasibility and diagnostic performance of intraoperative sonographic assessment of

Comparison of Laser Doppler Flowmetry With Contrast-Enhanced Ultrasound to Approximate Placental Microvascular Blood Flow in the African Green Monkey (Chlorocebus aethiops sabaeus). [PDF]

J Med Primatol
ABSTRACT Background The ability to study in vivo microvascular flow within the placenta is limited. We sought to compare two techniques for evaluation of placental perfusion in a translational nonhuman primate model. Methods We measured placental microvascular perfusion in six pregnant African green monkeys (Chlorocebus aethiops sabaeus) using both ...

Comparison of the SMI Technique and CEUS for the Assessment of Microvasculature in Leiomyosarcoma and Its Clinical Value for Application

Journal of Clinical Ultrasound, EarlyView.
SMI and CEUS can clearly reflect the microvascular situation in fibroids and effectively guide the clinical treatment of patients with uterine fibroids, but the effect of SMI is better than that of CEUS in guiding the treatment of patients, which can provide a reference for the selection of clinical treatment programs.

Preliminary Study on the Value of Contrast‐Enhanced Ultrasound in Enhancing Early Vascular Architecture for the Differential Diagnosis of Benign and Malignant Endometrial Lesions

Journal of Clinical Ultrasound, EarlyView.
This study aimed to analyze the microvascular morphology and distribution (i.e., early vascular architecture) of endometrial carcinoma lesions during the early enhancement phase using contrast‐enhanced ultrasound (CEUS). The results confirmed that quantitative parameters based on the early vascular architecture possess certain diagnostic efficacy for ...

Trans‐Fistula Contrast‐Enhanced Ultrasound in Diagnosing a Complex Anal‐Bartholin‐Perineal Fistula of Crohn's Disease: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates the potential utility of TF‐CEUS as a valuable adjunct in diagnosing complex fistulae. When MRI demonstrates limited sensitivity in detecting complex fistulae, TF‐CEUS can be chosen as a complementary imaging modality. It allows for real‐time, dynamic monitoring of the fistula branches, providing favorable conditions for early ...

Presentation of extramedullary myeloma manifestations on B-mode (B-US) and contrast-enhanced ultrasound (CEUS)

Journal of Ultrasonography
In patients with multiple myeloma, extramedullary myeloma manifestations can occur alongside bone marrow infiltration and osseous involvement. The aim of this study was to describe extramedullary myeloma manifestations using B-mode ultrasound and ...
