Examination of endobronchial ultrasound-guided transbronchial needle aspiration using a puncture needle with a side trap.

Sci Rep 2021 May 7;11(1):9789. Epub 2021 May 7.

Department of Respiratory Medicine, Yokohama Municipal Citizen's Hospital, Yokohama, Kanagawa, Japan.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is useful for diagnosing hilar and mediastinal lymph node enlargement; however, specimens obtained are often small and inadequate for pathologic diagnosis. In June 2017, EchoTip ProCore, a puncture needle with a side trap, was launched in Japan. In this single-center prospective interventional study, 57 patients with lymph nodes, intrapulmonary tumor or pleural mass were diagnosed using EBUS-TBNA with EchoTip ProCore between June 2017 and February 2020.

Department of Cardiovascular Surgery, Kartal Dr. Lutfi Kirdar City Hospital, Istanbul, Turkey.

Arterial injury during internal jugular vein cannulation can cause devastating complications such as stroke, hematoma, hemothorax, pseudoaneurysm, AV fistula, or even death. Acute upper limb ischemia caused by inadvertent arterial puncture during internal jugular vein cannulation has been rarely reported. The present report describes the case of a patient who experienced right upper limb ischemia caused by subclavian artery thrombosis developed during attempted placement of a tunneled hemodialysis catheter via the right internal jugular vein.

Catholic University Hospital, Rome, Italy.

Early in 2021, the Infusion Nursing Society has released the latest version of the Infusion Therapy Standards of Practice. In the last two decades, these Standards have been representing one of the most important evidence-based documents available in the world of venous access. Nevertheless, we were quite concerned reading a recommendation included in chapter 26 (Vascular Access Device Planning: practice recommendation I, C): "Use a patient's port, unless contraindicated (e.

Assessment of Commercial Off-the-Shelf Tissue Adhesives for Sealing Military-Relevant Corneal Perforation Injuries.

Mil Med 2021 May 7. Epub 2021 May 7.

Department of Sensory Trauma, United States Army Institute of Surgical Research, Fort Sam Houston, TX 78234, USA.

Introduction: Open-globe ocular injuries have increased in frequency in recent combat operations due to increased use of explosive weaponry. Unfortunately, open-globe injuries have one of the worst visual outcomes for the injured warfighter, often resulting in permanent loss of vision. To improve visual recovery, injuries need to be stabilized quickly following trauma, in order to restore intraocular pressure and create a watertight seal. Read More

PINK1 contained in huMSC-derived exosomes prevents cardiomyocyte mitochondrial calcium overload in sepsis via recovery of mitochondrial Ca efflux.

Stem Cell Res Ther 2021 May 6;12(1):269. Epub 2021 May 6.

Chongqing Key Laboratory of Pediatrics, Chongqing, People's Republic of China.

Background: Sepsis is a systemic inflammatory response to a local severe infection that may lead to multiple organ failure and death. Previous studies have shown that 40-50% of patients with sepsis have diverse myocardial injuries and 70 to 90% mortality rates compared to 20% mortality in patients with sepsis without myocardial injury. Therefore, uncovering the mechanism of sepsis-induced myocardial injury and finding a target-based treatment are immensely important. Read More

Follicular dendritic cell dysfunction contributes to impaired antigen-specific humoral responses in sepsis-surviving mice.

J Clin Invest 2021 May 6. Epub 2021 May 6.

Center for Autoimmune and Musculoskeletal Disease, The Feinstein Institutes for Medical Research, Manhasset, United States of America.

Sepsis survivors exhibit impaired responsiveness to antigen (Ag) challenge associated with increased mortality from infection. The contribution of follicular dendritic cells (FDCs) in the impaired humoral response in sepsis-surviving mice is investigated in this study. We demonstrated that mice subjected to sepsis from cecal ligation and puncture (CLP) have reduced NP-specific high-affinity class-switched Ig antibodies compared to sham control mice following immunization with the T-dependent Ag, NP-CGG.

Department of Oncology & Department of Breast Surgery, The Second Hospital of Dalian Medical University, Dalian, 116023, China.

Malignant pleural effusion (MPE) presents a severe medical condition in patients with advanced breast cancer (BC). We applied organoid culture technology to culture preoperative puncture specimen and corresponding surgical specimen-derived tumor cells from early BC patients and pleural effusion-derived tumor cells from advanced BC patients with MPE to study whether in vitro models could predict therapies of clinical patients. We successfully expanded pleural effusion-derived tumor organoids from 1 advanced triple-negative breast cancer (TNBC) patient with MPE which had been continuously propagated for more than 3 months.

Am J Med Sci 2020 Dec 5. Epub 2020 Dec 5.

Department of Cardiovascular Diseases, Penn State Health Milton S. Hershey Medical Center, Hershey, PA, USA.

Testing for collateral circulation of the hand before any radial artery procedure has been a subject of many controversies. Neither the Allen's test (AT) nor the plethysmography based Barbeau test, adequately and reliably test for collateral circulation. With growing interest in radial approaches for vascular procedures, its common use for arterial monitoring and blood gas sampling, there has been a growing interest in the relevance of assessing collateral hand circulation.
