Abstract
Background Although antihyperglycemic pharmacotherapy in frail older adults with type 2 diabetes mellitus (T2DM) is challenging, recommendations from international guidelines are mainly based on indirect evidence from trials not including frail participants. Objective This systematic review investigated the effectiveness and safety of pharmacotherapy in frail older adults with T2DM. Material and methods Randomized (RCT) and non-randomized prospective clinical trials (non-RCT) were searched in three electronic databases (Medline, Embase, Central) up to October 2018. Trials in older adults with T2DM who were assessed as significantly or severely impaired by defined cut-off scores of assessment instruments on frailty, activities of daily living or physical functional impairment were included. Results Two reviewers independently screened 17,391 references for inclusion and assessed risk of bias with ROBINS‑I. Five non-RCTs and no RCT were identified. Treatment of T2DM without insulin compared to insulin could be associated with increased improvement in cardiac functions in patients with cardiac resynchronization therapy and with decreased falls in frail older women. While better glycemic control with low variability and low HbA1c (hemoglobin A1c) values (<7%) was associated with better maintenance of physical function in community-dwelling older persons, higher HbA1c values (8–8.9%) were associated with a reduction in the composite outcome of death or functional decline in community-dwelling diabetic older adults with need for skilled assistance. Due to serious risk of bias in all studies, results should be considered with caution. Conclusion Well-designed, large-scale RCTs including this important group of patients are required to assess the effectiveness and safety of pharmacotherapy and HbA1c targets.

Abstract
This review considers the burden of mortality observed in the older population of people with diabetes and identifies the risk factors associated with mortality hazard in this population. The mortality gap between older people with and without diabetes is enduring, with excess mortality being 10% greater than in the general population. While early mortality in men with diabetes is significantly greater than females with diabetes, the relative mortality risk in females is much higher compared to women without diabetes. Older people who have developed diabetes in middle age have significantly higher mortality hazard compared to those who develop it in old age, emphasizing the continued importance of optimizing diabetes care in all ages. To minimize mortality hazard in older age it is important to address some of the factors that convey risk, these include: comorbidity; polypharmacy; physical and mental frailty; safe glycemic targets for older people; hypoglycemia; glycemic targets; and the hypoglycemic agents. While the data to determine optimal management approaches are limited, the overall need is for a more diligent approach in assessing the needs of older people with diabetes to inform individualized care strategies and therapy goals that minimize potential hazards.

Abstract
The impact of type 2 diabetes on ageing societies is great and populations across the globe are becoming more diverse. Complications of diabetes unequally affect particular groups in the UK older people, and people with a South Asian background are two population groups with increased risk whose numbers will grow in the future. We explored the evidence about diabetes care for older people with South Asian ethnicity to understand the contexts and mechanisms behind interventions to reduce inequalities. We used a realist approach to review the literature, mapped the main areas where relevant evidence exists, and explored the concepts and mechanisms which underpinned interventions. From this we constructed a theoretical framework for a programme of research and put forward suggestions for what our analysis might mean to providers, researchers, and policy makers. Broad themes of cultural competency; comorbidities and stratification; and access emerged as mid-level mechanisms which have individualised, culturally intelligent, and ethical care at their heart and through which inequalities can be addressed. These provide a theoretical framework for future research to advance knowledge about concordance; culturally meaningful measures of depression and cognitive impairment; and care planning in different contexts which support effective diabetes care for aging and diverse populations.
