Soft robotic platform for progressive and reversible aortic constriction in a small-animal model.

Our understanding of cardiac remodeling processes due to left ventricular pressure overload derives largely from animal models of aortic banding. However, these studies fail to enable control over both disease progression and reversal, hindering their clinical relevance. Here, we describe a method for progressive and reversible aortic banding based on an implantable expandable actuator that can be finely tuned to modulate aortic banding and debanding in a rat model.

Cryogenic focus measurement system for a wide-field infrared space telescope.

We describe a technique for measuring focus errors in a cryogenic, wide-field, near-infrared space telescope. The measurements are made with a collimator looking through a large vacuum window, with a reflective cold filter to reduce the background thermal infrared loading on the detectors and optics. The vacuum window and cold filter introduce a wavefront error that we characterize using an autocollimating microscope.

Imidazo[1,2-]pyridine and Imidazo[1,5-]pyridine: Electron Donor Groups in the Design of D-π-A Dyes.

This work investigates the electron-donating capabilities of two 10-π electron nitrogen bridgehead bicyclic [5,6]-fused ring systems, imidazo[1,2-]pyridine and imidazo[1,5-]pyridine rings. Eight compounds with varying positions of electron-withdrawing moieties (TCF or DCI) coupled to the imidazopyridine ring were synthesized and studied. DCI-containing compounds (-) exhibited a purely dipolar nature with broad absorption bands, weak fluorescence, large Stokes shifts, and strong solvatochromism.

Artificial Intelligence for Automatic Analysis of Shunt Treatment in Presurgery and Postsurgery Computed Tomography Brain Scans of Patients With Idiopathic Normal Pressure Hydrocephalus.

Background And Objectives: Ventriculo-peritoneal shunt procedures can improve idiopathic normal pressure hydrocephalus (iNPH) symptoms. However, there are no automated methods that quantify the presurgery and postsurgery changes in the ventricular volume for computed tomography scans. Hence, the main goal of this research was to quantify longitudinal changes in the ventricular volume and its correlation with clinical improvement in iNPH symptoms.

Endovascular intervention with intravascular ultrasound guidance of very early dissection complication in transplant renal artery: a case report and literature review.

Background: Transplant renal artery dissection (TRAD) is a rare and serious event that can cause allograft dysfunction and eventually graft loss. Most cases are managed by operative repair. We report a case of TRAD in the early postoperative period, which was successfully managed with intravascular ultrasound-assisted endovascular intervention.

Analysis of Common Exercise Modalities in Improving Athletic Performance in Older Adults: A Narrative Review.

Exercise leads to robust cardiovascular, musculoskeletal, and psychological benefits that improve quality of life and longevity for older adults, but accompanying improvements in athletic parameters are less well explored. The aim of this review is to summarize some of the most common exercise modalities, namely, Pilates, martial arts (tai chi, Japanese-style karate, hard martial arts), locomotion (brisk walking/jogging and running), Masters sports, resistance training, and high-intensity interval training, in improving athletic performance for older adults. Regular participation in these activities can have robust yet unique impacts on physical performance that prolong exercise participation.

Diagnosis and Management of Riga-Fede Disease: A Case Series.

In this case series, we present four unique cases of Riga-Fede disease (RFD), a rare disorder characterized by mucosal trauma as a result of repetitive tongue protrusion against the incisors, leading to the development of a large oral mass/ulceration. Due to the rapid development and growth of these lesions mimicking malignancy, it is important for the general and pediatric otolaryngologist to correctly diagnose and treat this benign disorder. This series highlights the variable clinical presentations, along with comorbidities of RFD, as well as the importance of interdisciplinary care between the pediatric otolaryngologist and pediatric dentist in its management.

Predicting radiation-induced immune suppression in lung cancer patients treated with stereotactic body radiation therapy.

Background: Stereotactic body radiation therapy (SBRT) is known to modulate the immune system and contribute to the generation of anti-tumor T cells and stimulate T cell infiltration into tumors. Radiation-induced immune suppression (RIIS) is a side effect of radiation therapy that can decrease immunological function by killing naive T cells as well as SBRT-induced newly created effector T cells, suppressing the immune response to tumors and increasing susceptibility to infections.

Purpose: RIIS varies substantially among patients and it is currently unclear what drives this variability.

Arthro-distension with early and intensive mobilization for shoulder adhesive capsulitis: A randomized controlled trial.

Background: There are several therapeutic options for the management of shoulder adhesive capsulitis (AC). The superiority of arthro-distension over intra-articular steroid injection (ISI) for AC remains controversial.

Objectives: To evaluate the efficacy of a single arthro-distension procedure combined with early and intensive mobilization (ADM) and physiotherapy, versus ISI and physiotherapy, in people with AC lasting ≥3 months.

Metastatic melanoma to the urinary bladder with synchronous or metachronous metastasis to other organs: Clinicopathological characteristics and outcome.

Introduction And Importance: Bladder metastatic melanoma is a very uncommon condition.

Case Presentation: On 62 reported cases, 55 studies have been done so far. We describe a 53-year-old woman with a hematuria who underwent transurethral resection of bladder lesions caused by metastatic melanoma for eight years ago after receiving her initial diagnosis of cutaneous malignant melanoma.

A Novel Ex Vivo Tumor Spheroid-Tissue Model for Investigating Microvascular Remodeling and Lymphatic Blood Vessel Plasticity.

Biomimetic tumor microenvironment models bridge the gap between in vitro and in vivo systems and serve as a useful way to address the modeling challenge of how to recreate the cell and system complexity associated with real tissues. Our laboratory has developed an ex vivo rat mesentery culture model, which allows for simultaneous investigation of blood and lymphatic microvascular network remodeling in an intact tissue environment. Given that angiogenesis and lymphangiogenesis are key contributors to the progression of cancer, the objective of this study was to combine tissue and tumor spheroid culture methods to establish a novel ex vivo tumor spheroid-tissue model by verifying its use for evaluating the effects of cancer cell behavior on the local microvascular environment.

Assessing mental health treatment receipt among Asian adults with limited English proficiency using an intersectional approach.

US Asian adults and people with limited English proficiency (LEP) confront mental health treatment receipt disparities. At the intersection of racial and language injustice, Asian adults with LEP may face even greater disparity, but studies have not assessed this through explicitly intersectional approaches. Using 2019 and 2020 National Survey of Drug Use and Health data, we computed disparities in mental health treatment among those with mental illness comparing: non-Hispanic (NH) Asian adults with LEP to NH White adults without LEP (joint disparity), NH Asian adults without LEP to NH White adults without LEP (referent race disparity), NH Asian adults with LEP to those without LEP (referent LEP disparity), and the joint disparity versus the sum of referent disparities (excess intersectional disparity).

A Rapid Review of Interventions to Improve Care for People Who Are Medically Underserved with Multiple Sclerosis, Diabetic Retinopathy, and Lung Cancer.

In the United States, patients with chronic conditions experience disparities in health outcomes across the care continuum. Among patients with multiple sclerosis, diabetic retinopathy, and lung cancer, there is a lack of evidence summarizing interventions to improve care and decrease these disparities. The aim of this rapid literature review was to identify interventions among patients with these chronic conditions to improve health and reduce disparities in screening, diagnosis, access to treatment and specialists, adherence, and retention in care.

Background: Venous thromboembolism is a preventable complication of gynecologic cancer surgery that leads to postoperative morbidity and mortality. This study compared apixaban with enoxaparin to identify whether apixaban had the same safety and efficacy for patients undergoing gynecologic cancer surgery.

Methods: The study identified patients with a gynecologic malignancy who underwent surgery and were prescribed apixaban at discharge between June 2020 and April 2023.

Impact of Pre-existing Type 2 Diabetes Mellitus and Cardiovascular Disease on Healthcare Resource Utilization and Costs in Patients With COVID-19.

The economic burden associated with type 2 diabetes mellitus (T2DM) and concurrent cardiovascular disease (CVD) among patients with COVID-19 is unclear. We compared healthcare resource utilization (HCRU) and costs in patients with COVID-19 and T2DM and CVD (T2DM + CVD), T2DM only, or neither T2DM nor CVD (T2DM/CVD). A retrospective observational study in COVID-19 patients using data from the Healthcare Integrated Research Database (HIRD®) was conducted.

Adaptability in the Midst of Anatomical Challenges: A Case of Situs Inversus Totalis in Laparoscopic Cholecystectomy.

Situs inversus totalis (SIT) is a rare and nonfatal congenital anomaly where there is a complete inversion of a patient's visceral organs. Throughout the patient's lifetime, they will encounter various challenges due to their unique anatomic variation. In this case, we report the treatment of symptomatic cholelithiasis in a 33-year-old female with comorbid SIT who underwent a laparoscopic cholecystectomy without postoperative complications.

The oral nucleoside prodrug GS-5245 is efficacious against SARS-CoV-2 and other endemic, epidemic, and enzootic coronaviruses.

Despite the wide availability of several safe and effective vaccines that prevent severe COVID-19, the persistent emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) that can evade vaccine-elicited immunity remains a global health concern. In addition, the emergence of SARS-CoV-2 VOCs that can evade therapeutic monoclonal antibodies underscores the need for additional, variant-resistant treatment strategies. Here, we characterize the antiviral activity of GS-5245, obeldesivir (ODV), an oral prodrug of the parent nucleoside GS-441524, which targets the highly conserved viral RNA-dependent RNA polymerase (RdRp).

Conventional clinical signs and symptoms are poor predictors of postoperative cerebrospinal fluid leak: A single-centre cohort perspective.

Background: Postoperative cerebrospinal fluid (CSF) leak remains a concerning complication of the endoscopic endonasal approach (EEA) for skull base pathology. Signs and symptoms suggesting CSF leak often trigger additional workup during the postoperative course. We systematically evaluate associations between subjectively reported clinical signs/symptoms noted during the immediate postoperative period and incidence of postoperative CSF leaks.
