"It is truly inspiring to see how many community groups held bake sales, car washes and other fundraisers for this cause, and I want to challenge more of them to join our team," said Manning, who pledged to match the first $100,000 in fundraising from local community groups – which they exceeded in just a few short months. Five of the most innovative, creative and successful fundraising campaigns created by kids and community groups were honored, resulting in a check for $250,000 from "Eli's Challenge" to the Tackle Kids Cancer program, which benefitted from the New York Giants support. "We value our relationship with Hackensack University Medical Center and are honored to be part of Tackle Kids Cancer. The work that is done by the Children's Cancer Institute and those who have contributed to Tackle Kids Cancer has served as an inspiration to Eli and all of us," said Allison Stangeby, vice president of Community and Corporate Relations. "We are proud of Eli's work in our community and his selfless support of the Children's Cancer Institute." The event was part of NBC4 Telemundo Health Expo, Presented by Quest Diagnostics, which is held annually at MetLife Stadium welcoming a wide range of healthy lifestyle exhibits, as well as free health tests and screenings. "The Foundation is proud of the partnership we have with the New York Giants and its players," said Jon M. Fitzgerald, president of Hackensack University Medical Center Foundation. "Eli Manning's commitment to Tackle Kids Cancer has extended far beyond what we could have imagined. Not only has he volunteered to be the face of our campaign, but he has made numerous visits with the children, families and health care team at our Children's Cancer Institute. With Eli's Challenge, he has taken his role as champion of this cause to higher level, and we could not have raised more than $4 million for our Tackle Kids Cancer initiative without his support." The Children's Cancer Institute at Hackensack University Medical Center consists of dedicated clinicians and researchers specializing in pediatric cancer. With more than 100 active oncology and transplant clinical trials currently open, it is leading the charge to cure childhood cancer. "While extremely rare, pediatric cancer is the number one cause of death by disease in children in the U.S.," said Stephen Percy, M.D., interim chairman, Department of Pediatrics, Joseph M. Sanzari Children's Hospital. "Every dollar received through the Tackle Kids Cancer campaign will support our most important programs and research."

Hackensack Meridian Health is a pioneer in operationalizing bundled payments, participating in the Centers for Medicare & Medicaid Services' (CMS) Comprehensive Care for Joint Replacement (CJR) since the program launched in April 2016. He also contributed to white papers published by Medscape Medical News from the American Society of Clinical Oncology (ASCO) and OncLive summarizing the outcomes and savings bundled care and alternative payment models offer. "CMS is working to encourage the adoption of value-based care models specifically because of the potential for improved outcomes and lower costs. Achieving these goals will take time, but we have to do it if we truly want to fix healthcare," said Dr. Pecora. "I believe that in the not-so-distant future patients and doctors will have the information they need to choose the correct bundles and lanes that make the best sense. Patients achieve the best clinical outcomes when care is tailored to their individual needs, and the total cost of care should be less for the entire population." Dr. Pecora, who also attended the 2016 White House-sponsored Cancer Moonshot Summit in Washington, DC to accelerate cancer research, is widely acknowledged as one of the world's leading experts in blood and marrow stem cell transplantation, cellular medicine and immunology research.

Conventional epithelioid hemangioendotheliomas (EHE) have a distinctive morphologic appearance and are characterized by a recurrent t(1;3) translocation, resulting in a WWTR1-CAMTA1 fusion gene. We have recently encountered a fusion-negative subset characterized by a somewhat different morphology, including focally well-formed vasoformative features, which was further investigated for recurrent genetic abnormalities. Based on a case showing strong transcription factor E3 (TFE3) immunoreactivity, fluorescence in situ hybridization (FISH) analysis for TFE3 gene rearrangement was applied to the index case as well as to nine additional cases, selected through negative WWTR1-CAMTA1 screening. A control group, including 18 epithelioid hemangiomas, nine pseudomyogenic HE, and three epithelioid angiosarcomas, was also tested. TFE3 gene rearrangement was identified in 10 patients, with equal gender distribution and a mean age of 30 years old. The lesions were located in somatic soft tissue in six cases, lung in three and one in bone. One case with available frozen tissue was tested by RNA sequencing and FusionSeq data analysis to detect novel fusions. A YAP1-TFE3 fusion was thus detected, which was further validated by FISH and reverse transcription polymerase chain reaction (RT-PCR). YAP1 gene rearrangements were then confirmed in seven of the remaining nine TFE3-rearranged EHEs by FISH. No TFE3 structural abnormalities were detected in any of the controls. The TFE3-rearranged EHEs showed similar morphologic features with at least focally, well-formed vascular channels, in addition to a variably solid architecture. All tumors expressed endothelial markers, as well as strong nuclear TFE3. In summary, we are reporting a novel subset of EHE occurring in young adults, showing a distinct phenotype and YAP1-TFE3 fusions. © 2013 Wiley Periodicals, Inc.

On Monday, November 7, 2016, board-certified orthopedic spine surgeon Dr. Nasser Ani performed a minimally invasive anterior cervical discectomy and fusion (ACDF) surgery on a 56-year-old female patient who was experiencing severe arm pain and numbness. The surgery took place at the Metropolitan Surgical Institute, an outpatient surgical center in South Amboy, New Jersey. The patient was suffering from cervical radiculopathy, with symptoms of radiating arm pain, as a result of a severe disc herniation causing compression of the spinal nerve roots at levels C5-6 and C6-7. After failed conservative treatment including physical therapy and spine epidural injections, the patient elected to have a two-level anterior cervical discectomy and fusion. Dr. Ani utilized a minimally invasive surgery to address the patient’s cervical radiculopathy and disc herniation. He chose an anterior surgical approach to gain exposure to the cervical spine through a small transverse incision in the neck. Dr. Ani was able to remove the herniated discs, and free the compressed and pinched nerves. After the discectomy, Dr. Ani inserted SpineFrontier’s biocompatible LES ARENA-C (HA) cervical cages to restore natural disc height between the vertebral bodies using the Less Exposure Surgery (LES) technique and placed a low-profile, two-level LES INVUE MAX cervical plate on the operative levels to provide stability until fusion takes place. Dr. Ani commented on the case: “The LES INVUE plate, when paired with the LES ARENA-C (HA) interbody, was one of the safest, most efficient ways to stabilize this patient’s spine. The instruments and procedural steps are easy. The hydroxyapatite (HA) infused LES ARENA-C spacer, together with a cancellous bone sponge and the patient’s own stem cells will result in an excellent fusion.” Dr. Ani stated that “minimally invasive surgery enables patients to return home just hours after surgery with little to no pain. This patient will be able to return to work in two to three weeks.” Dr. Nasser Ani is a board-certified orthopedic and spine surgeon at Ani Medical Group, Orthopedic and Spine Institute of New Jersey and deals with all aspects of spinal disorders, deformities and scoliosis. Initially, patients are treated in a conservative fashion in an effort to provide pain relief and help them return to functional status. However, in some cases, when conservative treatments fails, surgical options are discussed as a means to return patients back to their normal daily living activities. Dr. Ani is affiliated with multiple hospitals in the area, including Bayshore Community Hospital, Riverview Medical Center, Raritan Bay Medical Center, and Monmouth Medical Center. He is also the Chief of Orthopedics at Bayshore Community Hospital. He received his medical degree from the American University of Beirut, Lebanon. He completed an orthopedic surgery and spine fellowship at McGill University in Montreal, Canada. Dr. Ani has been in practice for over 25 years, double boarded in the fields of orthopedics and spinal surgery, and holds several professional affiliations including the North American Spine Society, Fellow of the American Academy of Orthopedics Surgeons, Fellow of the American College of Surgeons, Fellow of the Royal College of Surgeons, American Society for Laser Medicine and Surgery, and the American Medical Association, just to name a few.

To assess joint disease activity by ultrasound (US) in patients with rheumatoid arthritis (RA) initiating treatment with adalimumab (ADA) plus methotrexate (MTX).Data for this post hoc analysis originated from the MUSICA trial (ClinicalTrials.gov identifier: NCT01185288), which evaluated the efficacy of initiating ADA (40 mg every other week) plus 7.5 or 20 mg/week MTX in 309 patients with RA with an inadequate response to MTX. Synovial vascularization over 24 weeks was assessed bilaterally at metacarpophalangeal joint 2 (MCP2), MCP3, MCP5, metatarsophalangeal joint 5, and the wrists by power Doppler US (PDUS). A semiquantitative 4-grade scale was used. Disease activity was assessed using the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP) and Simplified Disease Activity Index (SDAI). The correlation between continuous variables was assessed using Pearsons correlation coefficient.After 24 weeks of treatment with ADA plus MTX, rapid improvements in the mean synovial vascularity score were observed; the greatest improvements were in MCP2 (-0.5), MCP3 (-0.4), and the wrist (-0.4). At week 24, patients with the lowest DAS28-CRP (<2.6) had the lowest mean 5-joint and 3-joint composite synovial vascularity scores. The 5-joint and 3-joint scores were strongly correlated (>0.9). Synovial vascularity scores correlated poorly with DAS28, swollen joint count in 66 joints (SJC66), SJC28, tender joint count in 68 joints (TJC68), TJC28, Clinical Disease Activity Index (CDAI), SDAI, physicians global assessment, patients global assessment of pain, and disease duration (<0.2). Thirty-two (70%) of 46 patients with a DAS28-CRP of <2.6, and 11 (58%) of 19 patients with an SDAI indicating remission had at least 1 joint with a synovial vascularity score of 1.PDUS detects changes in synovial vascularity in RA patients treated with ADA plus MTX, and residual synovial vascularity in patients in whom clinical disease control has been achieved.

The transcription factor NF-κB family is central for osteoclastogenesis and inflammatory osteolysis. Activation of NF-κB dimers is regulated by a kinase complex predominantly containing IKKα (IKK1), IKKβ (IKK2), and a regulatory subunit, IKKγ/NEMO. IKKα and IKKβ catalyze the cytoplasmic liberation and nuclear translocation of various NF-κB subunits. The requirement of IKKα and IKKβ for normal bone homeostasis has been established. Congruently, mice devoid of IKKα or IKKβ exhibit in vitro and in vivo defects in osteoclastogenesis, and IKKβ-null mice are refractory to inflammatory arthritis and osteolysis. To better understand the molecular mechanism underlying IKKβ function in bone homeostasis and bone pathologies, we conducted structure-function analysis to determine IKKβ functional domains in osteoclasts. IKKβ encompasses several domains, of which the ubiquitination-like domain (ULD) has been shown essential for IKKβ activation. In this study, we examined the role of ULD in IKKβ-mediated NF-κB activation in osteoclast precursors and its contribution to osteoclastogenesis and osteolysis. We generated and virally introduced IKKβ in which the ULD domain has been deleted (IKKβ-ULD) into osteoclast progenitors. The results show that deletion of ULD diminishes IKKβ activity and that IKKβ-ULD strongly inhibits osteoclastogenesis. In addition, unlike wild type (WT)-IKKβ, IKKβ-ULD fail to restore RANKL-induced osteoclastogenesis by IKKβ-null precursors. Finally, we provide evidence that IKKβ-ULD blocks inflammatory osteolysis in a model of murine calvarial osteolysis. Thus, we identified the ULD as crucial for IKKβ activity and osteoclastogenesis and found that ULD-deficient IKKβ is a potent inhibitor of osteoclastogenesis and osteolysis. © 2013 Springer Science+Business Media New York.
