Daratumumab for the numerous myeloma
Following the establishment of the Infectious Diseases Society of America (IDSA), women played a minor role as IDSA leaders, awards recipients, and presenters at the national meeting. Since the formation of the IDSA Women's Committee in 1992, women have played an increasing role in all of these domains of the Society. Two subsequent IDSA task forces have emphasized the importance of women, and other unrepresented minorities, to the success of the core missions of the Society. Ongoing efforts to maintain the presence of women and their unique talents, experiences, and understandings in the Society will sustain the strengths of IDSA.This article identifies the major elements of the strategic road map for the Infectious Diseases Society of America's (IDSA) Inclusion, Diversity, Access, and Equity (IDA&E) initiative and discusses the long-term goals and the proposed steps needed to achieve these goals.The fight for social justice and diversity in medicine stems from racial inequalities and discrimination that have permeated our society for centuries. As America has become more diverse in recent years, African American physicians remain largely underrepresented in the healthcare workforce and academic medicine. In the field of infectious diseases, one man, George W. Counts, has shouldered the struggle to end disparities in education, training, research, and academic advancement. This article celebrates his legacy and rekindles the discussion about inclusion, diversity, access, and equity in infectious diseases.Limited availability of proton irradiators optimized for high-dose-rate studies makes the preclinical research of proton FLASH therapy challenging. We assembled two proton irradiation platforms that are capable of delivering therapeutic doses to thin biological samples at dose rates equal to and above 100 Gy/s. We optimized and tested dosimetry protocols to assure accurate dose delivery regardless of the instantaneous dose rate. The simplicity of the experimental setups and availability of custom-designed sample holders allows these irradiation platforms to be easily adjusted to accommodate different types of samples, including cell monolayers, 3D tissue models and small animals. We have also fabricated a microfluidic flow-through device for irradiations of biological samples in suspension. We present one example of a measurement with accompanying preliminary results for each of the irradiation platforms. One irradiator was used to study the role of proton dose rate on cell survival for three cancer cell lines, while the other was used to investigate the depletion of oxygen from an aqueous solution by water radiolysis using short intense proton pulses. No dose-rate-dependent variation was observed between the survival fractions of cancer cells irradiated at dose rates of 0.1, 10 and 100 Gy/s up to 10 Gy. On the other hand, irradiations of Fricke solution at 1,000 Gy/s indicated full depletion of oxygen after proton doses of 107 Gy and 56 Gy for samples equilibrated with 21% and 4% oxygen, respectively.
Acquired chemoresistance is a major challenge in the clinical treatment of glioblastoma (GBM). Circular RNAs have been verified to play a role in tumor chemoresistance. However, the underlying mechanisms remain unclear. The aim of this study was to elucidate the potential role and molecular mechanism of circASAP1 in temozolomide resistance of GBM.
We analyzed circRNA alterations in recurrent GBM tissues relative to primary GBM through RNA sequencing. Real-time quantitative reverse transcription PCR (qRT-PCR) verified the expression of circASAP1 in tissues and cells. Selleckchem ORY-1001 Knockdown and overexpressed plasmids were used to evaluate the effect of circASAP1 on GBM cell proliferation and temozolomide-induced apoptosis. Mechanistically, fluorescent in situ hybridization, dual-luciferase reporter, and RNA immunoprecipitation assays were performed to confirm the regulatory network of circASAP1/miR-502-5p/NRAS. Intracranial tumors model was used to verify our findings in vivo.
CircASAP1 expression was significantly up-regulated in recurrent GBM tissues and temozolomide-resistant cell lines. CircASAP1 overexpression enhanced GBM cell proliferation and temozolomide-resistance, which could reduced by circASAP1 knockdown. Further experiments revealed that circASAP1 increasd the expression of NRAS via sponging miR-502-5p. Moreover, circASAP1 depletion effectively restored the sensitivity of temozolomide-resistant xenografts to temozolomide treatment in vivo.
Our data demonstrate that circASAP1 exerts regulatory functions in GBM and that ceRNA-mediated microRNA sequestration might be a potential therapeutic strategy for GBM treatment.

Early studies of narcolepsy after AS03-adjuvanted pandemic A/H1N12009 vaccine (Pandemrix) could not define the duration of elevated risk post-vaccination nor the risk in children aged under 5 years who may not present until much older.
Clinical information and sleep test results, extracted from hospital notes at 3 large pediatric sleep centers in England between September 2017 and June 2018 for narcolepsy cases aged 4-19 years with symptom onset since January 2009, were reviewed by an expert panel to confirm the diagnosis. Vaccination histories were independently obtained from general practitioners (GPs). The odds of vaccination in narcolepsy cases compared with the age-matched English population was calculated after adjustment for clinical conditions that were indications for vaccination. GP questionnaires were returned for 242 of the 244 children with confirmed narcolepsy. Of these 5 were under 5 years, 118 were 5-11 years, and 119 were 12-19 years old at diagnosis; 39 were vaccinated with Pandemrix befccine-attributable cases with late diagnoses. Absence of a compensatory drop in risk 1-8 years after vaccination suggests that Pandemrix does not trigger onsets in those in whom narcolepsy would have occurred later.
In this study, we found that vaccine-attributable cases have onset of narcolepsy within 12 months of Pandemrix vaccination. The attributable risk is higher than previously estimated in England because of identification of vaccine-attributable cases with late diagnoses. Absence of a compensatory drop in risk 1-8 years after vaccination suggests that Pandemrix does not trigger onsets in those in whom narcolepsy would have occurred later.
