Investigating misclassification of type 1 diabetes in a population-based cohort of British Pakistanis and Bangladeshis using polygenic risk scores.

Correct classification of type 1 (T1D) and type 2 diabetes (T2D) is challenging due to overlapping clinical features and the increasingly early onset of T2D, particularly in South Asians. Polygenic risk scores (PRSs) for T1D and T2D have been shown to work relatively well in South Asians, despite being derived from largely European-ancestry samples. Here we used PRSs to investigate the rate of potential misclassification of diabetes amongst British Bangladeshis and Pakistanis.

A qualitative systematic review of the impact of hearing on quality of life.

Purpose: Hearing loss, deafness, and other hearing-related conditions can significantly impact quality of life; numerous qualitative studies have sought to describe these impacts. Synthesis of these findings may provide additional or more robust insights.

Methods: A qualitative systematic review of studies reporting qualitative data relating to the impact of hearing problems on adults' health-related quality of life.

Genetic architecture of routinely acquired blood tests in a British South Asian cohort.

Understanding the genetic basis of routinely-acquired blood tests can provide insights into several aspects of human physiology. We report a genome-wide association study of 42 quantitative blood test traits defined using Electronic Healthcare Records (EHRs) of ~50,000 British Bangladeshi and British Pakistani adults. We demonstrate a causal variant within the PIEZO1 locus which was associated with alterations in red cell traits and glycated haemoglobin.
