Radiographics 2021 Sep 24:210019. Epub 2021 Sep 24.

From the Department of Radiology, Baylor College of Medicine, One Baylor Plaza, Houston, TX 77030 (N.C.); University of California San Diego Health, San Diego, Calif (C.B.S., K.J.F.); Montefiore Medical Center, Bronx, NY (V.C.); University of Texas Southwestern Medical Center, Dallas, Tex (D.T.F.); University of Michigan Medical School, Ann Arbor, Mich (W.R.M.); Yale School of Medicine, New Haven, Conn (S.S.A.); Memorial Sloan Kettering Cancer Center, New York, NY (R.K.G.D.); Naval Medical Center San Diego, San Diego, Calif (R.M.M.); Northwestern University, Chicago, Ill (A.A.B.); and University of Texas MD Anderson Cancer Center, Houston, Tex (K.M.E.).

Liver lesions have different enhancement patterns at dynamic contrast-enhanced imaging. The Liver Imaging Reporting and Data System (LI-RADS) applies the enhancement kinetic of liver observations in its algorithms for imaging-based diagnosis of hepatocellular carcinoma (HCC) in at-risk populations. Therefore, careful analysis of the spatial and temporal features of these enhancement patterns is necessary to increase the accuracy of liver mass characterization. Read More

Utility of "reposition-flap" in the reconstruction of the avulsed thumb.

Medicine (Baltimore) 2021 Sep;100(38):e27290

University of Medicine and Pharmacy "Grigore T. Popa", Strada Universitxăţii 16, Iaşi, Romania.

Abstract: Injuries that result in thumb amputation cause a loss of 50% of hand function. Microsurgical replantation remains the gold standard of thumb reconstruction techniques. The non-microsurgical technical variants of thumb reconstruction described so far aim to create a neo-thumb of adequate length, stable, opposable, sensitive, and last but not least esthetically pleasing appearance.

Chest X-ray in intensive care unit patients: what there is to know about thoracic devices.

Diagn Interv Radiol 2021 Sep;27(5):633-638

Department of Radiology, University of Trieste, Trieste, Italy.

Critically ill patients admitted to the intensive care unit require continuous monitoring of vital functions as well as mechanical and pharmacological support, provided through different devices. Chest radiographs play a fundamental role in monitoring the conditions of these patients and assessing the intensive-care devices after their insertion; therefore, the radiologist needs to know their normal appearance and their correct position and should be aware of the possible complications that may occur after their placement. This pictorial review illustrates the radiographic appearance of non-cardiological devices commonly used in clinical practice (central venous catheters, tunneled catheters, Swan-Ganz catheters, chest tubes, endotracheal tubes, and nasogastric tubes), their correct position and the most common complications that may occur after their placement.

Abandon "Race." Focus on Racism.

Front Public Health 2021 7;9:689462. Epub 2021 Sep 7.

Suzanne Dworak-Peck School of Social Work, University of Southern California, Los Angeles, CA, United States.

The concept of "race" emerged in the 1600s with the trans-Atlantic slave trade, justifying slavery; it has been used to justify exploitation, denigration and decimation. Since then, despite contrary scientific evidence, a deeply-rooted belief has taken hold that "race," indicated by, e.g. Read More

The Bubble Eye Sign: Understanding the Radiological Imaging of Gas inside the Orbit.

Indian J Radiol Imaging 2021 Apr 27;31(2):451-453. Epub 2021 Jul 27.

Department of Ophthalmology, Memorial Ophthalmic Centre, Tung Wah Eastern Hospital, Hong Kong.

Gas, appears as radiolucent on X-ray, is normally absent in the orbit. However, intraocular surgeries occasionally utilize retained intraocular gas for tamponade effect. Intravitreal gas persists after retinal surgery, being confounded by the scleral shell of the operated eye, outlines the shape of the eyeball, and gives the characteristic bubble appearance on skull X-ray.

Indian J Radiol Imaging 2021 Apr 27;31(2):345-349. Epub 2021 Jul 27.

Department of Radiology, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, India.

The increased use of new checkpoint inhibitors in cancer therapy has led to the discovery of new unconventional responses, like pseudoprogression and hyperprogression disease (HPD). The study documents imaging findings of HPD and analyzes the growth kinetics in advanced metastatic cancers patients treated with immunotherapy. We retrospectively reviewed patients treated with anti-PD-1 (anti-progressive disease-1) antibody therapy (nivolumab) between January 2017 and December 2017 at our institute. Read More

The emerging vertebrate model species for neurophysiological studies is Danionella cerebrum, new species (Teleostei: Cyprinidae).

Sci Rep 2021 Sep 23;11(1):18942. Epub 2021 Sep 23.

Naturhistorisches Museum Bern, 3005, Bern, Switzerland.

The four described species of Danionella are tiny, transparent fishes that mature at sizes between 10-15 mm, and represent some of the most extreme cases of vertebrate progenesis known to date. The miniature adult size and larval appearance of Danionella, combined with a diverse behavioral repertoire linked to sound production by males, have established Danionella as an important model for neurophysiological studies. The external similarity between the different species of Danionella has offered an important challenge to taxonomic identification using traditional external characters, leading to confusion over the identity of the model species.

[Surgical de-escalation for head and neck cancer surgery].

Bull Cancer 2021 Sep 20. Epub 2021 Sep 20.

Institut de cancérologie de Lorraine, département de chirurgie, 6, avenue de Bourgogne, 54519 Vandœuvre-lès-Nancy cedex, France.

Head and neck cancer surgery often has functional and aesthetic consequences. De-escalation surgery is a major concern for surgeons with a constant desire to develop surgical techniques with less invasive approaches and to preserve anatomical structures as much as possible. This was made possible by the appearance of minimally transoral and endonasal surgery as well as by the limitation of the surgical procedure by neoadjuvant treatments or by the limitation of surgical excision without compromising the oncological outcome and patient survival.

Generation of circular spin current in an AB magnetic ring with vanishing net magnetization: A new prescription.

J Phys Condens Matter 2021 Sep 23. Epub 2021 Sep 23.

Physics and Applied Mathematics Unit, Indian Statistical Institute, Kolkata, 203 Barrackpore Trunk Road, Calcutta-700108, Kolkata, West Bengal, 700108, INDIA.

In this work we report for the first time the appearance of non-decaying circular spin current in a magnetic ring with vanishing net magnetization, even in absence of any spin chirality. Breaking the symmetry in hopping integrals we can misalign up and down spin electronic energy levels which yields a net spin current in the magnetic quantum ring, threaded by an Aharonov-Bohm (AB) flux. Along with spin current, a net charge current also appears, and we compute both these currents using the second quantized approach. Read More

The Role of Attention in Multisensory Integration.

Authors:
Christopher Mole

Multisens Res 2020 Jul 8;34(3):337-349. Epub 2020 Jul 8.

Department of Philosophy, University of British Columbia, 1866 Main Mall, E370, Vancouver, BC, V6T 1Z1, Canada.

Evidence concerning the relationship between attention and multisensory integration has long been thought to lead us into a paradox. The paradox has its roots in evidence that seems to show that attention exerts an influence on integration, and that integration also exerts an influence on attention. This creates an appearance of paradox only if it is understood to imply that particular instances of the integration process must occur both before and after particular instances of the attention process.

Early IL-10 promotes vasculature-associated CD4+ T cells unable to control Mycobacterium tuberculosis infection.

JCI Insight 2021 Sep 23. Epub 2021 Sep 23.

Life and Health Sciences Research Institute (ICVS), University of Minho, Braga, Portugal.

Cytokine-producing CD4+ T cells play a crucial role in the control of Mycobacterium tuberculosis (Mtb) infection; however, there is a delayed appearance of effector T cells in the lungs following aerosol infection. The immunomodulatory cytokine IL-10 antagonizes control of Mtb infection through mechanisms associated with reduced CD4+ T cell responses. Here, we show that IL-10 overexpression only before the onset of the T cell response impairs control of Mtb growth. Read More
