Ultrasonography Grading of Internal Carotid Artery Disease: Multiparametric German Society of Ultrasound in Medicine (DEGUM) versus Society of Radiologists in Ultrasound (SRU) Consensus Criteria.

Ultraschall Med 2021 May 5. Epub 2021 May 5.

Department of Neurology, Universitätsklinikum Carl Gustav Carus, Dresden, Germany.

Purpose:  We sought to determine the diagnostic agreement between the revised ultrasonography approach by the German Society of Ultrasound in Medicine (DEGUM) and the established Society of Radiologists in Ultrasound (SRU) consensus criteria for the grading of carotid artery disease.

Materials And Methods:  Post-hoc analysis of a prospective multicenter study, in which patients underwent ultrasonography and digital subtraction angiography (DSA) of carotid arteries for validation of the DEGUM approach. According to DEGUM and SRU ultrasonography criteria, carotid arteries were independently categorized into clinically relevant NASCET strata (normal, mild [1-49 %], moderate [50-69 %], severe [70-99 %], occlusion).

PLoS One 2021 5;16(5):e0250813. Epub 2021 May 5.

Musculoskeletal Sciences and Sport Medicine Research Centre, Department of Life Sciences, Manchester Metropolitan University, Manchester, United Kingdom.

Background: Previous work suggest a positive skeletal muscle effect of hormone replacement therapy (HRT) on skeletal muscle characteristics This study aimed to quantify any continued positive effect of HRT even after a sustained hiatus in treatment, controlling for two key muscle modulation hormones: Estradiol (E2) and Tri-iodo-thyronine (T3).

Method And Findings: In 61 untrained women (18-78yrs) stratified as pre-menopausal, post-menopausal without (No_HRT) and post-menopausal with (Used_HRT) HRT history, body composition, physical activity, serum E2 and T3 were assessed by dual energy x-ray absorptiometry, Baecke questionnaire and ELISA.

Circulating T regulatory cells in patients with psoriasis with and without atherosclerosis: A pilot comparative study before and after photochemotherapy.

Photodermatol Photoimmunol Photomed 2021 May 5. Epub 2021 May 5.

Dermatology Department, Faculty of Medicine, Cairo University, Cairo, Egypt, PO box, 11562.

Evidence is accumulating proving the role of T regulatory cells (Tregs) in both psoriasis and atherosclerosis pathogenesis and treatment. Psoralen-ultraviolet A (PUVA) remains a standard line of therapy for psoriasis, particularly darker phototypes, whenever the risk-benefit ratio is waived carefully. Despite the well-known therapeutic effect of UV phototherapy on psoriasis cutaneous lesions, it is still unclear if its immunomodulatory function can positively impact cardiac comorbidities in patients with psoriasis, such as atherosclerosis.

Anesthesiology, Department of Medicine and Surgery, Critical Care and Pain Medicine Division, University of Parma, Viale Gramsci 14, 43126, Parma, Italy.

Lung ultrasound is a well-established diagnostic tool in acute respiratory failure, and it has been shown to be particularly suited for the management of COVID-19-associated respiratory failure. We present exploratory analyses on the diagnostic and prognostic performance of lung ultrasound score (LUS) in general ward patients with moderate-to-severe COVID-19 pneumonia receiving O supplementation and/or noninvasive ventilation. From March 10 through May 1, 2020, 103 lung ultrasound exams were performed by our Forward Intensive Care Team (FICT) on 26 patients (18 males and 8 females), aged 62 (54 - 76) and with a Body Mass Index (BMI) of 30.

Turk J Phys Med Rehabil 2021 Mar 4;67(1):111-114. Epub 2021 Mar 4.

Department of Physical Medicine and Rehabilitation, University of Health Sciences, Ankara Training and Research Hospital, Ankara, Turkey.

Undifferentiated connective tissue disease (UCTD) represents a group of diseases which do not fulfill the criteria of rheumatologic diseases or may be considered as an early stage of any of these diseases. Axial spondyloarthritis (axSpA) is a disease accompanied by symptoms of inflammatory low back pain and peripheral symptoms, with more spine and sacroiliac joint involvement. In this report, we, for the first time, present a case of UCTD presenting with axSpA in whom the initial finding was optic neuritis, which is rarely seen in UCTD. Read More

The sonographic identification of cortical bone interruptions in rheumatoid arthritis: a morphological approach.

Ther Adv Musculoskelet Dis 2021 16;13:1759720X211004326. Epub 2021 Apr 16.

Rheumatology Unit, Department of Clinical and Molecular Sciences, Polytechnic University of Marche, 'Carlo Urbani' Hospital, Jesi (Ancona), Italy.

Bone erosions are the hallmark of structural damage in rheumatoid arthritis (RA). Among imaging techniques, ultrasonography (US) has emerged as an accurate, reliable, repeatable, low-cost and non-invasive imaging modality to detect erosive changes in RA. However, small interruptions of the cortical bone detectable by last generation US equipment do not necessarily represent bone erosions. Read More

Department of Gastroenterology, University Teaching Hospital Lueneburg, Bögelstraße 1, Lueneburg 21339, Germany.

Treatment targets of inflammatory bowel diseases (IBD), ulcerative colitis (UC) and Crohn's disease (CD) have evolved over the last decade. Goals of therapy consisting of symptom control and steroid sparing have shifted to control of disease activity with endoscopic remission being an important endpoint. Unfortunately, this requires ileocolonoscopy, an invasive procedure. Read More

High-Frequency Acoustic Imaging Using Adhesive-Free Polymer Transducer.

Polymers (Basel) 2021 Apr 30;13(9). Epub 2021 Apr 30.

Department of Physics and Technology, UiT The Arctic University of Norway, 9019 Tromsø, Norway.

The piezoelectric polymer PVDF and its copolymers have a long history as transducer materials for medical and biological applications. An efficient use of these polymers can potentially both lower the production cost and offer an environment-friendly alternative for medical transducers which today is dominated by piezoelectric ceramics containing lead. The main goal of the current work has been to compare the image quality of a low-cost in-house transducers made from the copolymer P(VDF-TrFE) to a commercial PVDF transducer. Read More
