Blood Glucose Management of Type 2 Diabetes in the Older People

Effects of age and disease duration on the efficacy and safety of iGlarLixi in Asian people with type 2 diabetes: A post hoc analysis of the LixiLan-O-AP and LixiLan-L-CN trials

AIM

To evaluate the effect of age and disease duration on the efficacy and safety of iGlarLixi versus insulin glargine 100 units/ml (iGlar) or lixisenatide (Lixi) alone in Asian people with type 2 diabetes (T2D) uncontrolled on oral antidiabetic drugs (LixiLan-O-AP) or basal insulin ± oral antidiabetic drugs (LixiLan-L-CN).

MATERIALS AND METHODS

In this post hoc analysis, the glycated haemoglobin (HbA1c) changes were assessed from baseline to week 24 (LixiLan-O-AP) or 30 (LixiLan-L-CN) in subgroups defined by baseline age (<65, ≥65 years) and duration of T2D. The proportion who achieved the composite of HbA1c <7% (<53.0 mmol/mol) without weight gain and without symptomatic hypoglycaemia (plasma glucose ≤3.9 mmol/L) and the incidences of hypoglycaemia and gastrointestinal disorders were also analysed.

RESULTS

HbA1c reductions were consistently greater with iGlarLixi versus iGlar or Lixi across all subgroups, including participants aged ≥65 years and those with T2D for ≥15 or ≥20 years. Greater proportions of participants achieved HbA1c <7% (<53.0 mmol/mol) without weight gain or hypoglycaemia with iGlarLixi versus iGlar or Lixi, regardless of age or T2D duration. Hypoglycaemia incidence was similar with iGlarLixi versus iGlar across most subgroups; the incidence of gastrointestinal disorders was lower with iGlarLixi versus Lixi in all subgroups.

CONCLUSIONS

iGlarLixi showed consistent efficacy and safety across all age and disease duration subgroups in Asian people with uncontrolled T2D, including older individuals and those with longstanding disease.

Predictors of diabetes distress among older persons with type 2 diabetes mellitus in Indonesia

Background

Older persons living with diabetes have an obligation to change their daily lifestyle, which may contribute to diabetes distress. Furthermore, predictive factors of diabetes distress in older persons might be different from other age groups due to age-related factors.

Aims

The purpose of the study was to examine the predictive factors of diabetes distress in older persons diagnosed with type 2 diabetes mellitus (T2DM) in Indonesia.

Methods

A cross-sectional design was used in this study. Participants were recruited from an outpatient department of a tertiary hospital in Klaten City, Central Java, Indonesia. Data were analysed using multiple linear regression with a stepwise method.

Results

A total 198 older persons were included in the study. The study demonstrated self-efficacy (β = −0.298, P < 0.01), spirituality (β = −0.139, P < 0.05), blood glucose (β = 0.134, P < 0.05), and non-supportive family behaviour (β = 0.135, P < 0.05) as the variables that could statistically predict diabetes distress in older persons with T2DM.

Conclusions

Self-efficacy is the strongest predictor of diabetes distress. Moreover, the findings can be used as evidence to guide identification and future management of diabetes distress among older persons with T2DM.

Participation of Patients With Type 2 Diabetes in Online Support Groups is Correlated to Lower Levels of Diabetes Self-Management

BACKGROUND

Support groups play an important role in diabetes understanding and education. This study aims to find connections between participating in diabetes-related online communities (groups and forums) and the self-reported degree of self-care management and health problems associated with type 1 and 2 diabetes.

METHODS

A cross-sectional study using an online survey was conducted and 307 participants were recruited. Participants were asked about diabetes self-care management (glucose management, healthcare, dietary restrictions, and physical activity) and complications related to the disease, as well as their participation in online social groups and forums (duration, time, and intensity).

RESULTS

Belonging to diabetes-related online support groups (OSGs) was associated with lower scores in healthcare and self-management of diabetes (M = 2.98, SD = 1.07, n = 207, for belonging to OSGs; and M = 4.22, SD = 0.59, n = 97, for not belonging to OSGs). These differences were not statistically significant for type 1 diabetes individuals (M = 4.33, SD = 0.47, n = 28, for belonging to OSGs, and M = 4.29, SD = 0.48, n = 52, for not belonging to OSGs), but were highly significant for type 2 diabetes (T2D) individuals (M = 2.41, SD = 0.68, n = 144, for belonging to OSGs; and M = 4.14, SD = 0.64, n = 61, for not belonging to OSGs). People with both type 1 and 2 diabetes reported to have suffered more complications derived from diabetes when they belonged to an OSG, but greater statistically significant differences were found in type 2 individuals.

CONCLUSION

Patients with T2D who participate in OSGs show a higher correlation with having lower levels of diabetes self-care management as well as health complications related to the disease.

Prevalence of Diabetes Mellitus and Its Associated Factors in Bangladesh: Application of Two-level Logistic Regression Model

This study intends to explore the prevalence of diabetes mellitus (DM) and its associated factors in Bangladesh. The necessary information was extracted from Bangladesh Demographic and Health Survey (BDHS) 2011. In bivariate analysis, Chi-square test was performed to assess the association between selected covariates and diabetes status. A two-level logistic regression model with a random intercept at each of the individual and regional level was considered to identify the risk factors of DM. A total of 7,535 individuals were included in this study. From the univariate analysis, the prevalence of DM was found to be 33.3% in 50-54 age group for instance. In bivariate setup, all the selected covariates except sex of the participants were found significant for DM (p < 0.05). According to the two-level logistic regression model, the chance of occurring DM increases as age of the participants' increases. It was observed that female participants were more likely to have DM. The occurrence of DM was 62% higher for higher educated participants, 42% higher for the individuals who came from rich family and 63% higher for the individuals having hypertension. The chance of developing diabetes among overweighed people was almost double. However, the individuals engaged in physical work had less chance to have DM. This study calls for greater attention of government and other concerned entities to come up with appropriate policy interventions to lower the risk of DM.

Type 2 diabetes in older people: pathophysiology, identification and management

The general population is now living longer, with increasing numbers of older people living with more than one long-term condition. The number of older people diagnosed with type 2 diabetes is also rising because of the changes resulting from the ageing process and the significant increase in obesity levels, which are affecting the provision of healthcare and individuals' quality of life. This article explores the implications of increased longevity and how this is linked to the development of type 2 diabetes. It explains how the presentation of type 2 diabetes differs in older people compared with younger people, making initial diagnosis increasingly challenging. Frailty and anti-diabetes medicines can affect quality of life and an older person's risk of falls; therefore, linked to these, the article details the effects of declining functional ability and increasing cognitive impairment, and emphasises the need for regular medication reviews. The article also provides an analysis of the care required for older people with type 2 diabetes living in care homes, including the need for flexibility in treatment targets.

Role of ω3 polyunsaturated fatty acids in diabetic retinopathy: a morphological and metabolically cross talk among blood retina barriers damage, autoimmunity and chronic inflammation

Vision disorders are one of the most serious complications of diabetes mellitus (DM) affecting the quality of life of patients and eventually cause blindness. The ocular lesions in diabetes mellitus are located mainly in the blood vessels and retina layers. Different retina lesions could be grouped under the umbrella term of diabetic retinopathies (DMRP).

We propose that one of the main causes in the etiopathogenesis of the DMRP consists of a progressive loss of the selective permeability of blood retinal barriers (BRB). The loss of selective permeability of blood retinal barriers will cause a progressive autoimmune process. Prolonged autoimmune injures in the retinal territory will triggers and maintains a low-grade chronic inflammation process, microvascular alterations, glial proliferation and subsequent fibrosis and worse, progressive apoptosis of the photoreceptor neurons.

Patients with long-standing DM disturbances in retinal BRBs suffer of alterations in the enzymatic pathways of polyunsaturated fatty acids (PUFAs), increase release of free radicals and pro-inflammatory molecules and subsequently incremented levels of vascular endothelial growth factor. These facts can produce retinal edema and photoreceptor apoptosis.

Experimental, clinical and epidemiological evidences showing that adequate metabolic and alimentary controls and constant practices of healthy life may avoid, retard or make less severe the appearance of DMRP. Considering the high demand for PUFAs ω3 by photoreceptor complexes of the retina, it seems advisable to take fish oil supplements (2 g per day). The cellular, subcellular and molecular basis of the propositions exposed above is developed in this article.

Synthesizer drawings the most relevant findings of the ultrastructural pathology, as well as the main metabolic pathways of the PUFAs involved in balance and disbalanced conditions are provided.
