Glioblastoma and Increased Survival with Longer Chemotherapy Duration
Introduction
The five-year survival rate for patients with glioblastoma (GBM) is low at approximately 4.7%. Radiotherapy plus concomitant and adjuvant temozolomide (TMZ) remains the standard of care. The optimal duration of therapy with TMZ is unknown. This study sought to evaluate the survival benefit of two years of treatment.
Methods
This was a retrospective chart review of all patients diagnosed with GBM and treated with TMZ for up to two years between January 1, 2002 and December 31, 2011. The Kaplan-Meier method with log-rank test was used to estimate the progression-free survival (PFS) and the overall survival (OS). The results were compared to historical controls and data from previous clinical trials of patients treated up to one year.
Results
Data from 56 patients with confirmed GBM were evaluated. The OS probability was 54% (SE = 0.068) at one year, 28.3% (SE = 0.064) at two years, 17.8% (SE = 0.059) at three years, and 4% (SE = 0.041) at five years. Seven patients (12.5%) were treated with TMZ for two years. Their median time-to-progression was 28 months (95% CI = 5.0 - 28.0), and they had an increased survival probability at three years compared to other patients (log-rank test χ2 (1, N = 56) = 19.2, p < 0.0001).
Conclusions
There may be an advantage for a longer duration of TMZ therapy among patients with GBM, but the sample size was too small for generalization. A multicenter prospective study is needed to dentify optimal duration of TMZ therapy
May Measurement Month 2018: a pragmatic global screening campaign to raise awareness of blood pressure by the International Society of Hypertension
Aims
Raised blood pressure (BP) is the biggest contributor to mortality and disease burden worldwide and fewer than half of those with hypertension are aware of it. May Measurement Month (MMM) is a global campaign set up in 2017, to raise awareness of high BP and as a pragmatic solution to a lack of formal screening worldwide. The 2018 campaign was expanded, aiming to include more participants and countries.
Methods and results
Eighty-nine countries participated in MMM 2018. Volunteers (≥18 years) were recruited through opportunistic sampling at a variety of screening sites. Each participant had three BP measurements and completed a questionnaire on demographic, lifestyle, and environmental factors. Hypertension was defined as a systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg, or taking antihypertensive medication. In total, 74.9% of screenees provided three BP readings. Multiple imputation using chained equations was used to impute missing readings. 1 504 963 individuals (mean age 45.3 years; 52.4% female) were screened. After multiple imputation, 502 079 (33.4%) individuals had hypertension, of whom 59.5% were aware of their diagnosis and 55.3% were taking antihypertensive medication. Of those on medication, 60.0% were controlled and of all hypertensives, 33.2% were controlled. We detected 224 285 individuals with untreated hypertension and 111 214 individuals with inadequately treated (systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg) hypertension.
Conclusion
May Measurement Month expanded significantly compared with 2017, including more participants in more countries. The campaign identified over 335 000 adults with untreated or inadequately treated hypertension. In the absence of systematic screening programmes, MMM was effective at raising awareness at least among these individuals at risk

May Measurement Month 2019: an analysis of blood pressure screening results from Ghana-Sub-Saharan Africa
Raised blood pressure (BP) remains the biggest single risk factor contributing to the global burden of disease and to global mortality. Although a substantial number of people who have hypertension are either oblivious of it, not treated, or being managed but remain uncontrolled. May Measurement Month (MMM) is a global initiative led by the International Society of Hypertension (ISH) with the goal of increasing awareness of high BP and serving as a spur to establish screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2019. Measurement of BP and collection of relevant health information were performed according to a standardized protocol for MMM. Screening sites were set up in churches, mosques, health facilities, pharmacies, recreational parks, sports facilities, shopping centres, marketplaces, universities, workplaces, and community centres across four regions of Ghana. A total of 7102 participants gave their consent and were screened during MMM 2019. After multiple imputation, of all 7102 participants 1836 (25.9%) had hypertension. Of all 1836 participants with hypertension, 36.5% were aware of their status and 30.0% were on anti-hypertensive medication. Of 550 participants on antihypertensive medications, 46.1% had controlled BP (systolic BP <140 mmHg and diastolic BP <90 mmHg). Also, of all 1836 participants with hypertension, 13.8% had their BP controlled. Again, the proportion of participants with hypertension of those not receiving anti-hypertensive treatment was 1286 (19.6%). Data obtained from this project demonstrates that there is still a significant number of people with hypertension who are unaware of having it, are untreated, or are on treatment but remain uncontrolled. It also highlights the significance of BP screening campaigns as a tool to identify persons with elevated BP
May measurement month 2018: an analysis of blood pressure screening results from Ghana.
Elevated blood pressure (BP) is one of the leading risk factors for death and disability globally. It is also an important global health challenge because of its high prevalence and resulting morbidities. Albeit, a substantial number of people who have hypertension are either oblivious of it, not treated, or being managed but remain uncontrolled. May Measurement Month (MMM) is a global initiative led by the International Society of Hypertension (ISH) with the goal of increasing awareness of high BP and serving as a spur to establish screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2018. Measurement of BP and collection of relevant health information were performed according to a standardized protocol for MMM. Screening sites were set up in churches, mosques, health facilities, pharmacies, recreational parks, sports facilities, shopping centres, marketplaces, universities, workplaces, and community centres across four regions of Ghana. A total of 6907 participants were screened during MMM 2018. After multiple imputation, 2354 (34.1%) had hypertension. Of individuals not taking antihypertensive medications 1526 (25.1%) were hypertensive of whom 48.4% were aware of having it. Also, of individuals taking antihypertensive medications 432 (52.2%) had uncontrolled BP. Data obtained from this project demonstrates that a significant number of people with hypertension are unaware of having it, are untreated, or are on treatment but remain uncontrolled. It also highlights the effectiveness of BP screening campaigns as a tool to identify persons with elevated BP
A pooled analysis of outcomes according to cytogenetic abnormalities in patients receiving ixazomib- vs placebo-based therapy for multiple myeloma
Abstract Some cytogenetic abnormalities (CAs) are associated with poorer prognosis in multiple myeloma (MM); proteasome inhibitors appear to benefit patients with high-risk CAs. We evaluated 2247 MM patients from the TOURMALINE-MM1/-MM2/-MM3/-MM4 trials to assess the PFS benefit of ixazomib plus lenalidomide-dexamethasone (Rd) vs placebo-Rd (TOURMALINE-MM1/-MM2) or ixazomib vs placebo (TOURMALINE-MM3/-MM4) in specific high-risk CAs. After a pooled median follow-up of 25.6 months, the hazard ratio (HR) for PFS with ixazomib- vs placebo-based therapy for high-risk patients was 0.74 (95% confidence interval [CI]: 0.59–0.93; median PFS [mPFS] 17.8 vs 13.2 months), and 0.70 (95% CI: 0.62–0.80; mPFS 26.3 vs 17.6 months) for complementary standard-risk patients. The HR for expanded high-risk patients was 0.75 (95% CI: 0.64–0.87; mPFS 18.1 vs 14.1 months), and 0.71 (95% CI: 0.59–0.85; mPFS 36.1 vs 21.4 months) for complementary standard-risk patients. The HR for PFS with ixazomib- vs placebo-based therapy was 0.68 in patients with t(4;14) (95% CI: 0.48–0.96; mPFS 22.4 vs 13.2 months), and 0.77 for patients with amp1q21 (95% CI: 0.63–0.93; mPFS 18.8 vs 14.5 months). A PFS benefit was demonstrated with ixazomib- vs placebo-based therapy regardless of cytogenetic status, with greatest benefit observed in patients with t(4;14) and amp1q21
Food insecurity and pre-hypertension, pre-diabetes in adult women: results from the 2007-2010 National Health and Nutrition Examination Survey
Background
Being food insecure is generally defined as the limited or uncertain availability of safe and nutritious foods and is linked to poor nutrition and fully progressed diet-sensitive chronic diseases. However, little is known about the association between food insecurity and pre-clinical disease such as pre-hypertension and pre-diabetes. This study sought to examine the associations between food insecurity and pre-clinical disease among a racially/ethnically diverse population of women.
Methods
Using data from 2007-2010 NHANES, we examined associations between food security and pre-clinical disease among women 18-65 years. Chi-square tests were used to examine differences in demographic variables. Bivariate and multivariable generalized logistic regressions were used to generate odds ratios (ORs) with 95% confidence intervals (CIs) to assess the magnitude of associations between the presence of pre-clinical disease, sociodemographic characteristics, and food security.
Results
Food insecure women with very low food security (OR=2.69; 95% CI= 1.76-4.13) and low food security (OR=1.90; 95% CI= 1.20-3.02) had increased odds of having self-reported pre-hypertension. Food insecure women with very low food security (OR = 3.34; 95% CI= 1.40- 7.95), and low food security (OR = 2.81; 95% CI= 1.33- 5.93) had increased odds of pre-diabetes and pre-hypertension compared to food secure women.
Conclusions
Food insecurity is associated with having pre-hypertension alone or having a comorbidity of pre-hypertension and pre-diabetes among an adult female population
