Question: Abstract: BACKGROUND Glioblastoma, the most common primary brain tumor in adults, is usually rapidly fatal. The current standard of care for newly diagnosed glioblastoma is surgical resection to the extent feasible, followed by adjuvant radiotherapy. In this trial we compared radiotherapy alone with radiotherapy plus temozolomide, given concomitantly with and after radiotherapy, in terms of efficacy and safety.
METHODS Patients with newly diagnosed, histologically confirmed glioblastoma were randomly assigned to receive radiotherapy alone (fractionated focal irradiation in daily fractions of 2 Gy given 5 days per week for 6 weeks, for a total of 60 Gy) or radiotherapy plus continuous daily temozolomide (75 mg per square meter of body-surface area per day, 7 days per week from the first to the last day of radiotherapy), followed by six cycles of adjuvant temozolomide (150 to 200 mg per square meter for 5 days during each 28-day cycle). The primary end point was overall survival.
RESULTS A total of 573 patients from 85 centers underwent randomization. The median age was 56 years, and 84 percent of patients had undergone debulking surgery. At a median follow-up of 28 months, the median survival was 14.6 months with radiotherapy plus temozolomide and 12.1 months with radiotherapy alone. The unadjusted hazard ratio for death in the radiotherapy-plus-temozolomide group was 0.63 (95 percent confidence interval, 0.52 to 0.75; P<0.001 by the log-rank test). The two-year survival rate was 26.5 percent with radiotherapy plus temozolomide and 10.4 percent with radiotherapy alone. Concomitant treatment with radiotherapy plus temozolomide resulted in grade 3 or 4 hematologic toxic effects in 7 percent of patients.
CONCLUSIONS The addition of temozolomide to radiotherapy for newly diagnosed glioblastoma resulted in a clinically meaningful and statistically significant survival benefit with minimal additional toxicity.. Title: Breast cancer clusters in the northeast United States: a geographic analysis.

Question: Abstract: BACKGROUND Tuberculosis (TB) has been reported to be associated with poverty, especially in developing countries. Hong Kong is one of the few industrialised areas with a high incidence of TB where previous reports on the effect of poverty at neighbourhood level have been conflicting.
OBJECTIVE To examine the spatial distribution of TB and its association with neighbourhood risk factors.
METHOD A total of 17 294 TB cases notified from 2005 to 2007 were mapped down to the District Council Constituency Area (DCCA) level, and were indirectly standardised by age and sex using 2006 census population data. The standardised TB ratio was correlated with neighbourhood risk factors classified by family, ethnicity, economic and environmental domains.
RESULTS The indirect age- and sex-standardised ratio demonstrated a spatially varied pattern, and was significantly associated with all neighbourhood factors on univariate analysis. Only marital status, place of birth and low household income were independently associated with the standardised TB ratio on multivariate analysis.
CONCLUSION Despite the virtual elimination of absolute poverty by a well-developed social assistance scheme, low household income in the neighbourhood was significantly associated with TB, independently of place of birth, marital status and other risk factors..

Answer: yes

Question: Abstract: Nuclear receptors undergo ligand-dependent conformational changes that are required for corepressor-coactivator exchange, but whether there is an actual requirement for specific epigenetic landmarks to impose ligand dependency for gene activation remains unknown. Here we report an unexpected and general strategy that is based on the requirement for specific cohorts of inhibitory histone methyltransferases (HMTs) to impose gene-specific gatekeeper functions that prevent unliganded nuclear receptors and other classes of regulated transcription factors from binding to their target gene promoters and causing constitutive gene activation in the absence of stimulating signals. This strategy, based at least in part on an HMT-dependent inhibitory histone code, imposes a requirement for specific histone demethylases, including LSD1, to permit ligand- and signal-dependent activation of regulated gene expression. These events link an inhibitory methylation component of the histone code to a broadly used strategy that circumvents pathological constitutive gene induction by physiologically regulated transcription factors..
