The VEGF pathway has been recognized as a key mediator of angiogenesis to support tumorigenesis. Multiple therapeutic agents targeting VEGF and VEGF receptors have been developed and approved for use in NSCLCs. Preclinical studies have found that the VEGF and EGFR pathways share common downstream signaling, and these pathways can function exclusively of one another during oncogenesis. In EGFR-mutant NSCLCs, up-regulated EGFR signaling increases VEGF through hypoxia-independent mechanisms, and elevated VEGF, in turn, contributes to the emergence of resistance to EGFR tyrosine kinase inhibitors (TKIs). In clinical trials, the addition of anti-VEGF therapy to EGFR TKIs considerably improved clinical outcomes. In recently reported large randomized studies, the addition of bevacizumab or ramucirumab to EGFR TKIs substantially improved progression-free survival in patients with TKI-naive EGFR-mutant NSCLC. This article reviews the preclinical and clinical data supporting dual inhibition of EGFR and VEGF in EGFR-mutant NSCLC as a way to improve patient outcomes.
The combination of programmed cell death protein-1 or programmed death-ligand 1 immune checkpoint blockade and chemotherapy has revolutionized the treatment of advanced NSCLC, but the mechanisms underlying this synergy remain incompletely understood. In this study, we explored the relationships between neoadjuvant chemotherapy and the immune microenvironment (IME) of resectable NSCLC to identify novel mechanisms by which chemotherapy may enhance the effect of immune checkpoint blockade.

Genomic, transcriptomic, and immune profiling data of 511 patients treated with neoadjuvant chemotherapy followed by surgery (NCT) versus upfront surgery (US) were compared with determined differential characteristics of the IMEs derived from whole-exome sequencing (NCT= 18; US= 73), RNA microarray (NCT= 45; US= 202), flow cytometry (NCT= 17; US= 39), multiplex immunofluorescence (NCT= 10; US= 72), T-cell receptor sequencing (NCT= 16 and US= 63), and circulating cytokines (NCT= 18; US= 73).

NCT was associated with increased infiltration of cytotoxic CD8
T cells and CD20
B cells. Moreover, NCT was associated with increases in CD8
CD103
and CD4
CD103

TIM3
tissue resident memory T cells. selleckchem Gene expression profiling supported memory function of CD8
and CD4
T cells. However, NCT did not affect T-cell receptor clonality, richness, or tumor mutational burden. Finally, NCT was associated with decreased plasma BDNF (TrkB) at baseline and week 4 after surgery.

Our study supports that, in the context of resectable NSCLC, neoadjuvant chemotherapy promotes antitumor immunity through T and B cell recruitment in the IME and through a phenotypic change toward cytotoxic and memory CD8
and CD4
memory helper T cells.

Iron uptake mediated by transferrin receptor 1 (TfR1), encoded by the TFRC gene, is essential for lymphocyte development and proliferation. Autosomal-recessive mutations in the human TFRC gene cause a combined immunodeficiency characterized by defective T- and B-cell proliferation as well as impaired class-switching. Clinical presentations have been severe in all reported cases, with symptoms including recurrent sinopulmonary infections, hypogammaglobulinemia, chronic diarrhea, and intermittent cytopenias.

To describe outcomes of allogeneic hematopoietic stem cell transplantation (HSCT) in patients with TFRC deficiency.

Retrospective chart review study of 5 patients with TFRC deficiency who underwent allogeneic HSCT between July 2011 and May 2018 at Boston Children's Hospital.

Intermittent thrombocytopenia and neutropenia were a predominant feature of the clinical presentation in our cohort, and 3 patients who underwent bone marrow evaluation before HSCT were found to have signs of dysmyelopoiesis and

Patient was a 48-year-old, gravida 2 para 2, having had 2 normal spontaneous vaginal deliveries, with stage III anterior vaginal prolapse and stage III uterine prolapse and posterior vaginal prolapse. The preoperative vaginal length was 6 cm. Laparoscopic sacrocolpopexy is the current gold standard for pelvic organ prolapse demonstrating a low recurrence rate; however, it can be technically challenging to perform, particularly in women with obesity or in the event of an anatomic variation. The pectineal ligament, also known as Cooper's ligament, is familiar to surgeons and can be used for a tension-free mesh suspension in patients with prolapse. Integration of LESS and pectopexy is a novel alternative, minimally invasive approach that is more cosmetic, simpler, and effective. The key steps in LESS pectopexy include the following MEASUREMENTS AND MAIN RESULTS The procedure was performed successfully in approximately 80 minutes with a postoperative vaginal length of 6 cm. Postoperative pelvic organ prolapse quantification was stage 0.

LESS is a feasible technique for pectopexy in patients with pelvic organ prolapse. A LESS pectopexy results in better cosmesis and offers an alternative for patients with challenging pelvic organ prolapse, such as those with obesity.

The conservation of labiomental sensation by lateralization of the inferior alveolar nerve is unusual during a segmental mandibulectomy. A protocol for the evaluation of labiomental sensation has been created for the clinical follow-up of operated patients. The patients included were patients with mandibular osteoradionecrosis who underwent a segmental mandibulectomy with reconstruction by free fibular flap and whose pre-operative labiomental sensation was preserved. All patients were followed-up by the same examiner and operated on by the same surgeon. The neuro-sensitive examination analyses the different forms of sensation at 1 week and at 12 months postoperatively. Between May 2017 and May 2018, 3 consecutive patients were assessed. The results of the labiomental sensitive evaluation using our evaluation protocol attest to the preservation of labiomental sensation. The operating time was increased by an average of 35 min per surgical procedure.
