Two-Stage Mayo Clinic Class IIIb Celiac Axis Resection for Pancreatic Adenocarcinoma: Stepwise Management.

Background: The National Comprehensive Cancer Network guidelines consider pancreatic cancer with celiac axis (CA), proper hepatic artery (PHA), and superior mesenteric artery (SMA) involvement unresectable. Thus, technical reports and video illustrations of these operations are rare. We report the stepwise management of multivascular reconstruction for Mayo Clinic class IIIb CA resections at New York University Langone Health, a dedicated center of excellence in pancreatic surgery.

Muscle inflammation is regulated by NF-κB from multiple cells to control distinct states of wasting in cancer cachexia.

Although cancer cachexia is classically characterized as a systemic inflammatory disorder, emerging evidence indicates that weight loss also associates with local tissue inflammation. We queried the regulation of this inflammation and its causality to cachexia by exploring skeletal muscle, whose atrophy strongly associates with poor outcomes. Using multiple mouse models and patient samples, we show that cachectic muscle is marked by enhanced innate immunity.

Radiolabeling and Preclinical Evaluation of Therapeutic Efficacy of Ac-ch806 in Glioblastoma and Colorectal Cancer Xenograft Models.

The epidermal growth factor receptor (EGFR) protein is highly expressed in a range of malignancies. Although therapeutic interventions directed toward EGFR have yielded therapeutic responses in cancer patients, side effects are common because of normal-tissue expression of wild-type EGFR. We developed a novel tumor-specific anti-EGFR chimeric antibody ch806 labeled with Ac and evaluated its in vitro properties and therapeutic efficacy in murine models of glioblastoma and colorectal cancer.

Islet Isolation Outcomes in Patients Undergoing Total Pancreatectomy With Islet Autotransplantation in the POST Consortium.

Background: In total pancreatectomy with islet autotransplantation (TPIAT), a greater number of islets transplanted produces more favorable outcomes. We aimed to determine predictors of islet isolation outcomes.

Methods: We investigated factors associated with islet isolation outcomes expressed as islet number (IN), islet equivalents (IEQ; standardized to an islet with 150 μm diameter), IN/kg, or IEQ/kg using data from the multicenter Prospective Observational Study of TPIAT.

Diagnostic Positron Emission Tomography Imaging with Zirconium-89 Desferrioxamine B Squaramide: From Bench to Bedside.

Molecular imaging with antibodies radiolabeled with positron-emitting radionuclides combines the affinity and selectivity of antibodies with the sensitivity of Positron Emission Tomography (PET). PET imaging allows the visualization and quantification of the biodistribution of the injected radiolabeled antibody, which can be used to characterize specific biological interactions in individual patients. This characterization can provide information about the engagement of the antibody with a molecular target such as receptors present in elevated levels in tumors as well as providing insight into the distribution and clearance of the antibody.

Alpha-1 Antitrypsin Augmentation Therapy in Chronic Pancreatitis Patients Undergoing Total Pancreatectomy and Islet Autotransplantation: A Randomized, Controlled Study.

Stress-induced islet graft loss during the peri-transplantation period reduces the efficacy of islet transplantation. In this prospective, randomized, double-blind clinical trial, we evaluated the safety and efficacy of 60 mg/kg human alpha-1 antitrypsin (AAT) or placebo infusion weekly for four doses beginning before surgery in chronic pancreatitis (CP) patients undergoing total pancreatectomy and islet autotransplantation (TP-IAT). Subjects were followed for 12 months post-TP-IAT.

An Interpretive Description of Drug Withdrawal Among Pregnant Women in Jail.

Objective: To explore the experience of drug withdrawal among pregnant women in jail.

Design: A qualitative interpretive descriptive approach.

Setting/problem: The care of incarcerated pregnant women constitutes a complex and significant public health problem.

Tumor targeted alpha particle therapy with an actinium-225 labelled antibody for carbonic anhydrase IX.

Selective antibody targeted delivery of α particle emitting actinium-225 to tumors has significant therapeutic potential. This work highlights the design and synthesis of a new bifunctional macrocyclic diazacrown ether chelator, HMacropaSqOEt, that can be conjugated to antibodies and forms stable complexes with actinium-225. The macrocyclic diazacrown ether chelator incorporates a linker comprised of a short polyethylene glycol fragment and a squaramide ester that allows selective reaction with lysine residues on antibodies to form stable vinylogous amide linkages.

Real-World Incidence and Severity of Hypertension Caused by Abiraterone Acetate in Patients With Metastatic Prostate Cancer.

Background: Abiraterone acetate (AA) is used in treatment of patients with metastatic prostate cancer. Despite the survival advantage, AA is associated with hypertension due to mineralocorticoid excess syndrome.

Objective: We conducted a single-center retrospective analysis to evaluate the real-world incidence and severity of AA-induced hypertension.

Use of Digital Health Resources by Sexual and Gender Minority Caregivers of Older Adults: Findings From the 2020 Survey.

We applied Andersen's Behavioral Model of Health Services Use to investigate the health needs and use of digital health resources among sexual and/or gender minority (SGM) caregivers. Data were from the 2020 survey. Regression analyses were used to describe associations between predisposing, enabling, and need factors and usage of digital health resources.

Update on Total Pancreatectomy With Islet Autotransplantation.

Total pancreatectomy with islet autotransplantation is a therapeutic option to effectively achieve pain relief and improvements in quality of life for selected patients with debilitating pain from chronic pancreatitis. The understanding of the best application and clinical execution of this procedure is in evolution, with outcomes studies and clinical trials in progress.

Theranostic Nuclear Medicine with Gallium-68, Lutetium-177, Copper-64/67, Actinium-225, and Lead-212/203 Radionuclides.

Molecular changes in malignant tissue can lead to an increase in the expression levels of various proteins or receptors that can be used to target the disease. In oncology, diagnostic imaging and radiotherapy of tumors is possible by attaching an appropriate radionuclide to molecules that selectively bind to these target proteins. The term "theranostics" describes the use of a diagnostic tool to predict the efficacy of a therapeutic option.

Fiber-reinforced composite full-arch prosthetic reconstructions supported by three standard, short or extra-short implants: a two-center retrospective study.

Objectives: To evaluate the survival of implants and prostheses, and marginal bone level of fiber-reinforced composite implant supported fixed complete prostheses supported by 3 implants.

Materials And Methods: Patients with fiber-reinforced composite fixed prostheses supported by 3 standard-length, short or extra-short implants were included in this retrospective cohort study. Kaplan-Meier survival was computed for implants and prostheses.

Dose Intensity in Real-World Patients With Metastatic Renal Cell Carcinoma Taking Vascular Endothelial Growth Factor Receptor Tyrosine Kinase Inhibitors.

Background: Tyrosine kinase inhibitors (TKIs) that target the vascular endothelial growth factor receptor (VEGFR) are oral therapies used to treat metastatic renal cell carcinoma (mRCC). VEGFR TKI treatment is often complicated by dose-limiting adverse events (AE). We sought to describe dose intensity and clinical outcomes in a real-world cohort of patients treated with VEGFR TKIs to better characterize dosing patterns and toxicity management compared with previously reported clinical trials.

Pre-targeting amyloid-β with antibodies for potential molecular imaging of Alzheimer's disease.

With the aim of developing the concept of pretargeted click chemistry for the diagnosis of Alzheimer's disease two antibodies specific for amyloid-β were modified to incorporate -cyclooctene functional groups. Two bis(thiosemicarbazone) compounds with pendant 1,2,4,5-tetrazine functional groups were prepared and radiolabelled with positron emitting copper-64. The new copper-64 complexes rapidly react with the -cyclooctene functionalized antibodies in a bioorthogonal click reaction and cross the blood-brain barrier in mice.

How research into healthcare staff use and non-use of e-books led to planning a joint approach to e-book policy and practice across UK and Ireland healthcare libraries.

The research goals were to obtain an understanding of who the users of e-books in the NHS are, what they are using e-books for, and when and how they use them. This article presents the methodology used and the findings from the research. It also explores the outputs and next steps from the research, both for the individual countries and collectively.

Giant clams as open-source, scalable reef environmental biomonitors.

Valvometry, the electronic measurement of bivalve shell opening and closing, has been demonstrated to be a valuable biomonitoring technique in previous ecological and environmental studies. Valvometric data has been shown to relate significantly to pollution, predation, animal stress and feeding activity. However, there is a need for valvometric techniques applicable to coral reef environments, which may provide critical insights into reef resilience to ocean warming and acidification.

Balance effects of tactile stimulation at the foot.

Balance relies on several types of sensory information, including somatosensory senses such as touch and position sense (proprioception). As these senses decline in older adults, there is a question of whether shoes limit somatosensory feedback from the floor. Textured insoles are designed to stimulate the soles of the feet to enhance tactile feedback.

A randomized controlled trial of emotion regulation therapy for cancer caregivers: A mechanism-targeted approach to addressing caregiver distress.

Background: Caregivers of patients with cancer play a crucial role in the health of the person they care for, and in the healthcare system at large. Family caregivers receive minimal support, despite being at greater risk for anxiety and depression than patients themselves. Cognitive behavioral therapy (CBT), an effective therapy for anxiety and depression, has shown mixed efficacy when delivered to cancer caregivers.

Stem Cell Therapy Improves Human Islet Graft Survival in Mice via Regulation of Macrophages.

Islet/β-cell transplantation offers great hope for patients with type 1 diabetes. We assessed the mechanisms of how intrahepatic coinfusion of human α-1 antitrypsin (hAAT)-engineered mesenchymal stromal cells (hAAT-MSCs) improves survival of human islet grafts posttransplantation (PT). Longitudinal in vivo bioluminescence imaging studies identified significantly more islets in the livers bearing islets cotransplanted with hAAT-MSCs compared with islets transplanted alone.

Response to Selpercatinib in a Patient With Recurrent Glioblastoma and RET Amplification.

Glioblastoma (GBM) is a malignant central nervous system neoplasm that remains largely incurable. Limited treatment options currently exist after disease progression on standard-of-care first-line therapy. However, repurposing the use of approved therapies in patients with potentially targetable genomic alterations continues to be an emerging area of interest.
