Information comparing treatment outcome for diffuse large B cell (DLBCL) and follicular (FL) non-Hodgkin lymphoma (NHL) patients treated with schemes with and without rituximab from low- and middle-income countries is scarce. Clinical characteristics, response to therapy and long-term outcome of DLBCL and FL patients were studied. ⋯ Addition of rituximab to CHOP-like regimens did not improve OS in DLBCL and FL NHL subtypes. In comparison to developed countries, diagnosis of NHL was made a decade earlier and in advanced clinical stages. Cost-efficiency of adding rituximab to therapy for these patients should be assessed.

Atherosclerotic cardiovascular disease (ACD) is the leading cause of mortality worldwide. The objective of this paper is to provide an overview of the global burden of ACD and its risk factors and to discuss the main challenges and opportunities for prevention. Publicly available data from the Global Burden of Disease Study were analyzed for ischemic heart disease (IHD), ischemic stroke and ACD risk factors. ⋯ High levels of body mass index (BMI), blood pressure, glucose and cholesterol have a differential contribution to mortality by income group over time; high-income countries have been able to reduce the contribution from these risk factors in the last 20 years, whereas lower/middle income countries show an increasing trend in mortality attributable to high BMI and glucose. Although age-adjusted ACD mortality rate trends decreased globally, the absolute number of ACD deaths is increasing in part due to the growth of the population and aging, as well as to important lifestyle and food-system changes that likely attenuate gains in prevention. Population and individual level preventable causes of ACD must be aggressively and efficiently targeted in countries of lower economic development in order to reduce the growing burden of disease due to ACD.

Review Meta Analysis
Intramyocardial Autologous Bone Marrow-derived Stem Cells Injection for Ischemic Heart Disease Ineligible for Revascularization: A Systematic Review and Meta-analysis.
Intramyocardial autologous bone marrow-derived stem cells injection (IM-BMCs) has been used in patients with ischemic heart disease (IHD) who are ineligible for revascularization; however, the procedure has yielded mixed results. The objective of this meta-analysis was to evaluate the safety and therapeutic benefits of this treatment on a relatively large scale. ⋯ IM-BMC therapy showed clinical safety while being used as stand-alone treatment in IHD with no option of revascularization. The therapeutic efficacy requires further confirmation in large well-powered trials with long-term follow-up.

Review Meta Analysis
Associations among four polymorphisms (BsmI, FokI, TaqI and ApaI) of vitamin D receptor gene and end-stage renal disease: a meta-analysis.
To evaluate the association between vitamin D receptor (VDR) BsmI, FokI, TaqI and ApaI gene polymorphisms and the risk of end-stage renal disease (ESRD). ⋯ Results from the current study suggest that VDR BsmI, FokI, TaqI and ApaI gene polymorphisms are not associated with the risk of ESRD in the overall populations, Asians and Caucasians. However, more studies should be performed in the future.

The blood-brain barrier (BBB) is essential for normal function of the brain, and its role in many brain pathologies has been the focus of numerous studies during the last decades. Dysfunction of the BBB is not only being shown in numerous brain diseases, but animal studies have indicated that it plays a direct key role in the genesis of neurovascular dysfunction and associated neurodegeneration. As such evidence accumulates, the need for robust and clinically applicable methods for minimally invasive assessment of BBB integrity is becoming urgent. ⋯ First, imaging modalities are reviewed, with a focus on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). We then proceed to review image analysis methods, including quantitative and semi-quantitative methods. The advantages and limitations of each approach are discussed, and future directions and questions are highlighted.
