Megaprosthesis Versus Allograft Prosthesis Composite for the Management of Massive Skeletal Defects: A Meta-Analysis of Comparative Studies.

Curr Rev Musculoskelet Med 2021 Apr 17. Epub 2021 Apr 17.

Department of Orthopedics, All India Institute of Medical Sciences (AIIMS), New Delhi, 110029, India.

Purpose Of Review: Megaprosthesis and Allograft Prosthesis Composite (APC) are the established treatment modalities for massive skeletal defects. There are a handful of studies comparing the use of megaprosthesis and APC in the management of substantial bone loss and it has always been a topic of debate regarding the superiority of one modality over the other. Therefore, we aim to compare the functional outcome and implant survivorship of each modality including complications, revision rates, amputation rate and mortality. Read More

Enhancement of jaw bone regeneration via ERK1/2 activation using dedifferentiated fat cells.

Cytotherapy 2021 Apr 13. Epub 2021 Apr 13.

Oral Medicine Research Center, Fukuoka Dental College, Fukuoka, Japan.

Background Aims: Mesenchymal stem/stromal cells (MSCs) are multipotent and self-renewing cells that are extensively used in tissue engineering. Adipose tissues are known to be the source of two types of MSCs; namely, adipose tissue-derived MSCs (ASCs) and dedifferentiated fat (DFAT) cells. Although ASCs are sometimes transplanted for clinical cytotherapy, the effects of DFAT cell transplantation on mandibular bone healing remain unclear. Read More

EBioMedicine 2021 Apr 13;66:103327. Epub 2021 Apr 13.

Department of Hematology, Oncology, and Tumor Immunology, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Augustenburger Platz 1, Berlin 13353, Germany; German Cancer Consortium (DKTK), partner site Berlin, Berlin, Germany; German Cancer Research Center (DKFZ), Heidelberg, Germany. Electronic address:

Background: high recurrence rates of up to 75% within 2 years in pancreatic ductal adenocarcinoma (PDAC) patients resected for cure indicate a high medical need for clinical prediction tools and patient specific treatment approaches. Addition of the EGFR inhibitor erlotinib to adjuvant chemotherapy failed to improve outcome but its efficacy in some patients warrants predictors of responsiveness.

Patients And Methods: we analysed tumour samples from 293 R0-resected patients from the randomized, multicentre phase III CONKO-005 trial (gemcitabine ± erlotinib) with targeted sequencing, copy number, and RNA expression analyses. Read More

Novel Graft Technique for Lumbopelvic Reconstruction After Sacral Tumor Resection: A Case Report.

Authors:
Robert F McLain

JBJS Case Connect 2021 Apr 16;11(2). Epub 2021 Apr 16.

Spine and Orthopaedic Institute, St Vincent Charity Medical Center, Adjunct, Biomedical Engineering, Cleveland State University.

Case: Reconstruction after sacral tumor resection carries a high risk of nonunion and requires a slow return to weight-bearing. A bilateral iliac-crest graft, mobilized on a muscular pedicle, was used to graft and fuse the spine and pelvis after resection of a massive sacral schwannoma. Long-term follow-up and three-dimensional computed tomography imaging demonstrate rapid incorporation and solid fusion, with hypertrophy of the graft struts and excellent return to function.

α4β7 Integrin expression and blockade in pediatric and young adult gastrointestinal graft-versus-host disease.

Pediatr Blood Cancer 2021 Apr 16:e28968. Epub 2021 Apr 16.

Division of Bone Marrow Transplant and Immune Deficiency, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, USA.

Background: We hypothesized that α4β7 integrin expression on effector memory T cells (TEMs) would be elevated in pediatric hematopoietic stem cell transplant (HSCT) patients before and at diagnosis of acute gastrointestinal graft-versus-host disease (GI GVHD) symptoms compared to patients without GVHD, and that clinical blockade of α4β7 integrin with vedolizumab would be effective in pediatric GI GVHD.

Methods: We analyzed surface expression of α4β7 integrin on T cells from 48 pediatric allogeneic HSCT recipients from our biorepository with known clinical outcomes as follows: acute GI GVHD (n = 22), isolated skin GVHD (n = 12), and no GVHD (n = 14). T-cell analyses were performed 1 week before and at GVHD diagnosis in patients with GVHD, and day +30 after HSCT in patients without GVHD. Read More

Genetic therapies for the first molecular disease.

J Clin Invest 2021 Apr;131(8)

Department of Hematology.

Sickle cell disease (SCD) is a monogenic disorder characterized by recurrent episodes of severe bone pain, multi-organ failure, and early mortality. Although medical progress over the past several decades has improved clinical outcomes and offered cures for many affected individuals living in high-income countries, most SCD patients still experience substantial morbidity and premature death. Emerging technologies to manipulate somatic cell genomes and insights into the mechanisms of developmental globin gene regulation are generating potentially transformative approaches to cure SCD by autologous hematopoietic stem cell (HSC) transplantation.
