Pattern of Relapse and Treatment Response in WNT- Activated Medulloblastoma
Over the past decade, wingless-activated (WNT) medulloblastoma has been identified as a candidate for therapy de-escalation based on excellent survival; however, a paucity of relapses has precluded additional analyses of markers of relapse. To address this gap in knowledge, an international cohort of 93 molecularly confirmed WNT MB was assembled, where 5-year progression-free survival is 0.84 (95%, 0.763-0.925) with 15 relapsed individuals identified. Maintenance chemotherapy is identified as a strong predictor of relapse, with individuals receiving high doses of cyclophosphamide or ifosphamide having only one very late molecularly confirmed relapse (p = 0.032). The anatomical location of recurrence is metastatic in 12 of 15 relapses, with 8 of 12 metastatic relapses in the lateral ventricles. Maintenance chemotherapy, specifically cumulative cyclophosphamide doses, is a significant predictor of relapse across WNT MB. Future efforts to de-escalate therapy need to carefully consider not only the radiation dose but also the chemotherapy regimen and the propensity for metastatic relapses
Frum with Benefits: Israeli Television, Globalization, and Srugimâs American Appeal
Srugim (Yes, Channel 2) is a popular Israeli television series that ran for three seasons, from 2008 to 2012. The show focuses on a group of single Religious Zionists in their late twenties and early thirties who live in the Katamon neighborhood of Jerusalem, nicknamed âthe Swampâ for its dense population of single religious Jews hoping to find spouses. Srugim examines the charactersâ search for love and meaning amid the conflicting tensions of religious observance and secular mores. In addition to domestic success, the show has attracted a small but significant American following, which I argue is due to reasons of content and distribution. First among these is the showâs focus on love with religiously celibate characters. With a focus on dating in the âbig cityâ of Jerusalem, Srugim normalizes Religious Zionist Jews by showing how delayed marriage aff ects Orthodox Israeli Jews. Second, the rise of digital television viewing enabled Srugimâs exposure to a wide audience in the United States by way of its availability on Hulu and Amazon Prime. Its cult success speaks to the possibilities of niche series using familiar genres to appeal to international audiences in a globalized television market
Use of Geographic Information Systems for Planning HIV Prevention Interventions for High-Risk Youths
Geographic information system (GIS) analysis is an emerging tool for public health intervention planning. Connect to Protect, a researcherâcommunity collaboration working in 15 cities to reduce HIV infection among youths, developed GIS databases of local health, crime, and demographic data to evaluate the geographic epidemiology of sexually transmitted infections and HIV risk among adolescents
A quantitative approach for the analysis of clinician recognition of acute respiratory distress syndrome using electronic health record data.
ImportanceDespite its efficacy, low tidal volume ventilation (LTVV) remains severely underutilized for patients with acute respiratory distress syndrome (ARDS). Physician under-recognition of ARDS is a significant barrier to LTVV use. We propose a computational method that addresses some of the limitations of the current approaches to automated measurement of whether ARDS is recognized by physicians.ObjectiveTo quantify patient and physician factors affecting physicians' tidal volume selection and to build a computational model of physician recognition of ARDS that accounts for these factors.Design, setting, and participantsIn this cross-sectional study, electronic health record data were collected for 361 ARDS patients and 388 non-ARDS hypoxemic (control) patients in nine adult intensive care units at four hospitals between June 24 and December 31, 2013.MethodsStandardized tidal volumes (mL/kg predicted body weight) were chosen as a proxy for physician decision-making behavior. Using data-science approaches, we quantified the effect of eight factors (six severity of illness, two physician behaviors) on selected standardized tidal volumes in ARDS and control patients. Significant factors were incorporated in computational behavioral models of physician recognition of ARDS.ResultsHypoxemia severity and ARDS documentation in physicians' notes were associated with lower standardized tidal volumes in the ARDS cohort. Greater patient height was associated with lower standardized tidal volumes (which is already normalized for height) in both ARDS and control patients. The recognition model yielded a mean (99% confidence interval) physician recognition of ARDS of 22% (9%-42%) for mild, 34% (19%-49%) for moderate, and 67% (41%-100%) for severe ARDS.Conclusions and relevanceIn this study, patient characteristics and physician behaviors were demonstrated to be associated with differences in ventilator management in both ARDS and control patients. Our model of physician ARDS recognition measurement accounts for these clinical variables, providing an electronic approach that moves beyond relying on chart documentation or resource intensive approaches
