Genetic Variants Within the Erythroid Transcription Factor, KLF1, and Reduction of the Expression of Lutheran and Other Blood Group Antigens: Review of the In(Lu) Phenotype.

Erythroid-specific Krüppel-like factor 1, or KLF1, is an integral transcriptional activator for erythropoiesis. Genetic variants within KLF1 can result in a range of erythropoietic clinical phenotypes from benign to significant. The In(Lu) phenotype refers to changes in the quantitative expression of blood group-associated red cell surface molecules due to KLF1 variants which are otherwise clinically benign.

Investigation of the variable In(Lu) phenotype caused by KLF1 variants.

Introduction: KLF1 is an essential transcriptional activator that drives erythropoiesis. KLF1 variants can result in the Inhibitor of Lutheran, or In(Lu), phenotype where red blood cells (RBCs) have reduced BCAM (LU) and CD44 (IN). Other RBC surface molecules also have changed expression; however, there is controversy in the literature regarding which are truly impacted.

The global Optima HIV allocative efficiency model: targeting resources in efforts to end AIDS.

Background: To move towards ending AIDS by 2030, HIV resources should be allocated cost-effectively. We used the Optima HIV model to estimate how global HIV resources could be retargeted for greatest epidemiological effect and how many additional new infections could be averted by 2030.

Methods: We collated standard data used in country modelling exercises (including demographic, epidemiological, behavioural, programmatic, and expenditure data) from Jan 1, 2000, to Dec 31, 2015 for 44 countries, capturing 80% of people living with HIV worldwide.

In the interests of time: improving HIV allocative efficiency modelling via optimal time-varying allocations.

Introduction: International investment in the response to HIV and AIDS has plateaued and its future level is uncertain. With many countries committed to ending the epidemic, it is essential to allocate available resources efficiently over different response periods to maximize impact. The objective of this study is to propose a technique to determine the optimal allocation of funds over time across a set of HIV programmes to achieve desirable health outcomes.

Reorienting the HIV response in Niger toward sex work interventions: from better evidence to targeted and expanded practice.

Background: Niger's low-burden, sex-work-driven HIV epidemic is situated in a context of high economic and demographic growth. Resource availability of HIV/AIDS has been decreasing recently. In 2007-2012, only 1% of HIV expenditure was for sex work interventions, but an estimated 37% of HIV incidence was directly linked to sex work in 2012.

Who pays and why? Costs, effectiveness, and feasibility of HIV treatment as prevention.

Treatment as prevention (TasP) has been added to the toolbox of human immunodeficiency virus (HIV) prevention technologies, and countries are at different stages of TasP deployment. In this article we review some of the cost implications and summarize effectiveness data from different settings. Also, we reflect on the affordability and feasibility of programmatic deployment as well as the multiple challenges of maintaining service quality while HIV treatment programs grow in size and complexity.

Children's attitudes and behavioural intentions towards a peer with symptoms of ADHD: does the addition of a diagnostic label make a difference?

This article explores the impact of diagnostic/psychiatric labelling on the attitudes and behavioural intentions of school-aged children towards a hypothetical peer presented with symptoms of attention deficit hyperactivity disorder (ADHD). A sample of 120 children aged 11-12 years read one of three vignettes describing the behaviour of a gender-neutral, same-age peer presenting with symptoms of ADHD. The participants completed self-report measures of attitudes and behavioural intentions after reading the respective vignettes.
