Team Integrated Enhanced Recovery (TIGER) Protocol after Adolescent Idiopathic Scoliosis Correction Lowers Direct Cost and Length of Stay While Increasing Daily Contribution Margins.

Introduction: Posterior spinal fusion (PSF) is the gold standard procedure for curve correction in Adolescent Idiopathic Scoliosis (AIS). Enhanced recovery protocols (ERPs) have been found to decrease pain and hospital length of stay (LOS) resulting in decreased total hospital charges.

Methods: We identified all adolescent idiopathic scoliosis patients treated with a posterior spinal fusion at our children's hospital between 2015-2019.

Hepatocellular Carcinoma: The Role of MicroRNAs.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. HCC is diagnosed in its advanced stage when limited treatment options are available. Substantial morphologic, genetic and epigenetic heterogeneity has been reported in HCC, which poses a challenge for the development of a targeted therapy.

Advances in Receptor-Targeted Radiolabeled Peptides for Melanoma Imaging and Therapy.

Melanocortin-1 receptor (MC1R) and very late antigen-4 (VLA-4, integrin αβ) are 2 attractive molecular targets for developing peptide radiopharmaceuticals for melanoma imaging and therapy. MC1R- and VLA-4-targeting peptides and peptide-conjugated Cornell prime dots (C' dots) can serve as delivery vehicles to target both diagnostic and therapeutic radionuclides to melanoma cells for imaging and therapy. This review highlights the advances of MC1R- and VLA-4-targeted radiolabeled peptides and peptide-conjugated C' dots for melanoma imaging and therapy.

Natural proteins and polysaccharides in the development of micro/nano delivery systems for the treatment of inflammatory bowel disease.

Treatments for inflammatory bowel disease (IBD) are typically immunosuppressive. Despite a range of treatment options, limited efficacy, systemic toxicities like bone marrow suppression, infections and malignancy are their serious setbacks. There exists an unmet medical need for novel therapeutic agents without safety concerns resulting from chronic, systemic immunosuppression.

Natural Product-Based Nanomedicine in Treatment of Inflammatory Bowel Disease.

Many synthetic drugs and monoclonal antibodies are currently in use to treat Inflammatory Bowel Disease (IBD). However, they all are implicated in causing severe side effects and long-term use results in many complications. Numerous in vitro and in vivo experiments demonstrate that phytochemicals and natural macromolecules from plants and animals reduce IBD-related complications with encouraging results.

Targeted melanoma radiotherapy using ultrasmall Lu-labeled α-melanocyte stimulating hormone-functionalized core-shell silica nanoparticles.

Lutetium-177 (Lu) radiolabeled ultrasmall (~6 nm dia.) fluorescent core-shell silica nanoparticles (Cornell prime dots or C' dots) were developed for improving efficacy of targeted radiotherapy in melanoma models. PEGylated C' dots were surface engineered to display 10-15 alpha melanocyte stimulating hormone (αMSH) cyclic peptide analogs for targeting the melanocortin-1 receptor (MC1-R) over-expressed on melanoma tumor cells.

Defects in long-chain 3-hydroxy acyl-CoA dehydrogenase lead to hepatocellular carcinoma: A novel etiology of hepatocellular carcinoma.

The incidence of both nonalcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC) have been increasing at an alarming rate. Little is known about NAFLD without cirrhosis as a risk for HCC. Here we report, for the first time, generation of a mouse model with a defect in long-chain 3-hydoxy acyl-CoA dehydrogenase (LCHAD).

RNA cargos in extracellular vesicles derived from blood serum in pancreas associated conditions.

Exosomes are extracellular vesicles which are released from healthy and tumor cells into blood circulation. Unique biomolecular cargos such as RNA and protein are loaded in these vesicles. These molecules may have biological functions such as signaling, cell communications and have the potential to be analyzed as biomarkers.

A Genomic Profile of Local Immunity in the Melanoma Microenvironment Following Treatment with α Particle-Emitting Ultrasmall Silica Nanoparticles.

An α particle-emitting nanodrug that is a potent and specific antitumor agent and also prompts significant remodeling of local immunity in the tumor microenvironment (TME) has been developed and may impact the treatment of melanoma. Biocompatible ultrasmall fluorescent core-shell silica nanoparticles (C' dots, diameter ∼6.0 nm) have been engineered to target the melanocortin-1 receptor expressed on melanoma through α melanocyte-stimulating hormone peptides attached to the C' dot surface.

Molecular phenotyping and image-guided surgical treatment of melanoma using spectrally distinct ultrasmall core-shell silica nanoparticles.

Accurate detection and quantification of metastases in regional lymph nodes remain a vital prognostic predictor for cancer staging and clinical outcomes. As intratumoral heterogeneity poses a major hurdle to effective treatment planning, more reliable image-guided, cancer-targeted optical multiplexing tools are critically needed in the operative suite. For sentinel lymph node mapping indications, accurately interrogating distinct molecular signatures on cancer cells in vivo with differential levels of sensitivity and specificity remains largely unexplored.

Ultrasmall Renally Clearable Silica Nanoparticles Target Prostate Cancer.

Although important advances have been achieved in the development of radiolabeled prostate-specific membrane antigen (PSMA)-targeting ligand constructs for both diagnosis and therapy of prostate cancer (PCa) over the past decade, challenges related to off-target effects and limited treatment responses persist. In this study, which builds upon the successful clinical translation of a series of ultrasmall, dye-encapsulating core-shell silica nanoparticles, or Cornell Prime Dots (C' dots), for cancer management, we sought to address these limitations by designing a dual-modality, PSMA-targeting platform that evades undesirable accumulations in the salivary glands, kidneys, and reticuloendothelial system, while exhibiting bulk renal clearance. This versatile PCa-targeted particle imaging probe offers significant clinical potential to improve future theranostic applications in a variety of patient care settings.

Ultrasmall targeted nanoparticles with engineered antibody fragments for imaging detection of HER2-overexpressing breast cancer.

Controlling the biodistribution of nanoparticles upon intravenous injection is the key to achieving target specificity. One of the impediments in nanoparticle-based tumor targeting is the inability to limit the trafficking of nanoparticles to liver and other organs leading to smaller accumulated amounts in tumor tissues, particularly via passive targeting. Here we overcome both these challenges by designing nanoparticles that combine the specificity of antibodies with favorable particle biodistribution profiles, while not exceeding the threshold for renal filtration as a combined vehicle.

Lupus Nephritis: A Treatment Update.

Background: Lupus nephritis (LN) is a common complication in many patients with systemic lupus erythematosus, although renal-limited lupus nephritis has been reported as well. Early diagnosis of lupus nephritis is critical as early detection and effective treatment can improve renal outcomes in such patients.

Objective: The treatment of lupus nephritis is largely determined based on the histological class present on the renal biopsy specimen.

Melanocortin-1 Receptor-Targeting Ultrasmall Silica Nanoparticles for Dual-Modality Human Melanoma Imaging.

The poor prognosis associated with malignant melanoma has not changed substantially over the past 30 years. Targeted molecular therapies, such as immunotherapy, have shown promise but suffer from resistance and off-target toxicities, underscoring the need for alternative therapeutic strategies that can be used in combination with existing protocols. Moreover, peptides targeting melanoma-specific markers, like the melanocortin-1 receptor (MC1-R), for imaging and therapy exhibit high renal uptake that limits clinical translation.

Obstructive Sleep Apnea Diagnosis and Management.

The diagnosis and treatment of obstructive sleep apnea is discussed in the context of recent diagnostic and therapeutic advances.

Life threatening nutritional deficiencies in a dialysis patient.

Nutritional deficiencies are very common among the patient on chronic hemodialysis. But they can be easily overlooked or misdiagnosed. Deficiencies of trace elements and phosphorous is rare among this patient population but if neglected can lead to catastrophic effects.

Peritoneal Dialysis in Patients with Abdominal Surgeries and Abdominal Complications.

Peritoneal dialysis (PD) is an excellent treatment option for the patients with end-stage renal disease, having been shown to yield improved patient satisfaction and economic benefit. Many surgeons and physicians believe that patients with prior abdominal surgeries or other abdominal complications are not viable candidates for PD and that prevalent PD patients needing abdominal surgery should be switched to hemodialysis. The purpose of the present review is to address those misconceptions.

The Triad of Sleep Apnea, Hypertension, and Chronic Kidney Disease: A Spectrum of Common Pathology.

Obstructive sleep apnea (OSA), hypertension, and chronic kidney disease (CKD) are different entities and are generally managed individually most of the time. However, CKD, OSA, and hypertension share many common risk factors and it is not uncommon to see this complex triad together. In fact, they share similar pathophysiology and have been interlinked with each other.

Protective Effects of AGE and Its Components on Neuroinflammation and Neurodegeneration.

Garlic (Allium sativum) is used for culinary and medicinal purposes in diverse cultures worldwide. When fresh garlic is soaked in aqueous ethanol under ambient environment over 4 months or longer, the majority of irritating taste and odor is eliminated and the antioxidant profile in the resulting aged garlic extract (AGE) changes significantly. Recently, AGE and its components have been demonstrated to exert neuroprotective effects in neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and cerebral ischemia.

Quantitative Proteomic Approaches for Analysis of Protein S-Nitrosylation.

S-Nitrosylation is a redox-based post-translational modification of a protein in response to nitric oxide (NO) signaling, and it participates in a variety of processes in diverse biological systems. The significance of this type of protein modification in health and diseases is increasingly recognized. In the central nervous system, aberrant S-nitrosylation, due to excessive NO production, is known to cause protein misfolding, mitochondrial dysfunction, transcriptional dysregulation, and neuronal death.

Proteomic analysis of the effects of aged garlic extract and its FruArg component on lipopolysaccharide-induced neuroinflammatory response in microglial cells.

Aged garlic extract (AGE) is widely used as a dietary supplement, and is claimed to promote human health through anti-oxidant/anti-inflammatory activities with hypolipidemic, antiplatelet and neuroprotective effects. Prior studies of AGE have mainly focused on its organosulfur compounds, with little attention paid to its carbohydrate derivatives, such as N-α-(1-deoxy-D-fructos-1-yl)-L-arginine (FruArg). The goal of this study is to investigate actions of AGE and FruArg on antioxidative and neuroinflammatory responses in lipopolysaccharide (LPS)-activated murine BV-2 microglial cells using a proteomic approach.

Bacterial quorum sensing molecule N-3-oxo-dodecanoyl-L-homoserine lactone causes direct cytotoxicity and reduced cell motility in human pancreatic carcinoma cells.

In spite of chemotherapeutic and surgical advances, pancreatic cancer continues to have a dismal prognosis. Metastasis due to tumor cell migration remains the most critical challenge in treating pancreatic cancer, and conventional chemotherapy is rarely curative. In the quest for more novel molecules to fight this disease, we tested the hypothesis that the Pseudomonas aeruginosa quorum sensing signal molecule N-3-oxo-dodecanoyl-L-homoserine lactone (O-DDHSL) would be cytotoxic to and reduce mobility of pancreatic carcinoma cells (Panc-1 and Aspc-1).
