PROBLEM: Abstract: Broadly neutralizing antibodies against highly variable viral pathogens are much sought after to treat or protect against global circulating viruses. Here we probed the neutralizing antibody repertoires of four human immunodeficiency virus (HIV)-infected donors with remarkably broad and potent neutralizing responses and rescued 17 new monoclonal antibodies that neutralize broadly across clades. Many of the new monoclonal antibodies are almost tenfold more potent than the recently described PG9, PG16 and VRC01 broadly neutralizing monoclonal antibodies and 100-fold more potent than the original prototype HIV broadly neutralizing monoclonal antibodies. The monoclonal antibodies largely recapitulate the neutralization breadth found in the corresponding donor serum and many recognize novel epitopes on envelope (Env) glycoprotein gp120, illuminating new targets for vaccine design. Analysis of neutralization by the full complement of anti-HIV broadly neutralizing monoclonal antibodies now available reveals that certain combinations of antibodies should offer markedly more favourable coverage of the enormous diversity of global circulating viruses than others and these combinations might be sought in active or passive immunization regimes. Overall, the isolation of multiple HIV broadly neutralizing monoclonal antibodies from several donors that, in aggregate, provide broad coverage at low concentrations is a highly positive indicator for the eventual design of an effective antibody-based HIV vaccine..

SOLUTION: yes

PROBLEM: Abstract: Defective hematopoiesis supporting capacity of bone marrow (BM) stroma has been implicated in the pathophysiology of myelodysplastic syndromes (MDS). The aim of this study is to explore whether the BM stroma progenitors, namely the mesenchymal stem cells (MSCs), are primarily affected in MDS by evaluating the reserves, the functional properties, as well as the cytogenetic characteristics, in comparison to BM hematopoietic cells, in patients with de novo MDS (n = 13). The number, differentiation potential toward adipocytes/chondrocytes/osteoblasts and immunosuppressive function in terms of inhibition of mitogen-induced T-cell proliferation did not differ significantly between patient and normal (n = 20) MSCs. Patient MSCs did not show any aberrations in the production of proinflammatory or growth-promoting cytokines and did not harbor the cytogenetic abnormalities present in hematopoietic cells. Occasional patient and normal MSC cultures, however, developed irrelevant chromosomal alterations (trisomies 5 and 7) with uncertain pathophysiologic significance. Compared to controls, patient MSCs displayed impaired proliferative and clonogenic potential through passages that might represent a nonspecific abnormality associated with the chronic inflammatory process present in patients' BM. These data suggest that BM MSCs from MDS patients do not belong to the abnormal clone and do not represent the main cellular source contributing to the inflammatory marrow microenvironment..

SOLUTION: no

PROBLEM: Abstract: Psychosocial factors have significant potential to affect long-term outcomes of bariatric surgery, including emotional adjustment, adherence to the recommended postoperative lifestyle regimen, weight loss outcomes, and co-morbidity improvement and or resolution. Thus, it is recommended that bariatric behavioral health clinicians with specialized knowledge and experience be involved in the evaluation and care of patients both before and after surgery. The evaluating clinician plays a number of important roles in the multidisciplinary treatment of the bariatric patient. Central among these is the role of identifying factors that may pose challenges to optimal surgical outcome and providing recommendations to the patient and bariatric team on how to address these issues. This document outlines recommendations for the psychosocial evaluation of bariatric surgery patients, appropriate qualifications of those conducting these evaluations, communication of evaluation results and suggested treatment plan, and the extension of behavioral healthcare of the bariatric patient to the entire span of the surgical and postsurgical process.. Title: Recommendations for the presurgical psychosocial evaluation of bariatric surgery patients.
