Association Between the Severity of Diabetic Retinopathy and Falls in an Asian Population With Diabetes: The Singapore Epidemiology of Eye Diseases Study

Prevalence and factors associated with falls in older adults in a Middle Eastern population: a retrospective cross-sectional study

OBJECTIVE

The main objective was to determine the prevalence of falls and associated factors in older adults living in Qatar.

STUDY DESIGN

Cross-sectional study.

METHODS

This is a cross-sectional study of older adults aged ≥60 years with at least one encounter with primary health care corporation (PHCC) in Qatar during the period 2017-2022. Data on documented falls, demographic variables, and medical comorbidities were extracted from all PHCCs in Qatar. Descriptive and inferential statistics were used to address the aim of the study.

RESULTS

A total of 68,194 older adults had at least one encounter with PHCC. The median age was 65.0 years, 58.9% were males, and 32.6% were Qatari nationality. A higher percentage of falls was found in individuals with hypertension (80%), diabetes (74.2%), and dyslipidemia (48.9%), which were also the most prevalent comorbidities. The prevalence of falls was 6.7% (95% CI 6.6-6.9). Compared to individuals aged 60-69 years, individuals aged 70-79, 80-89, and 90-99 had increased odds of falls by 1.6 (95% CI 1.5, 1.8), 2.5 (95% CI 2.2, 2.8), and 2.6 (95% CI 2.0, 3.3), respectively. Females and individuals of Qatari nationality had increased odds of fall by 1.5 (95% CI 1.4, 1.6) and 1.2 (95% CI 1.1, 1.3), respectively. Orthostatic hypotension, syncope, Parkinson's disease, and hip arthritis showed the strongest associations with falls.

CONCLUSIONS

Given the growing population of older adults in the Middle East and North African region, falls is a public health concern. The risk factors identified in this study suggest the need for proactive healthcare strategies tailored to the unique needs of older adult populations.

Clinical outcomes of multidimensional association of type 2 diabetes mellitus, COVID-19 and sarcopenia: an algorithm and scoping systematic evaluation

BACKGROUND

The aim of this study was to provide a scoping and comprehensive review for the clinical outcomes from the cross-link of Type 2 diabetes mellitus (T2DM), COVID-19, and sarcopenia.

METHODS

By using PRISMA guidelines and searching through different databases that could provide findings of evidence on the association of T2DM, COVID-19, and sarcopenia.

RESULTS

Thirty-three studies reported a relationship between sarcopenia with T2DM, twenty-one studies reported the prognosis COVID-19 in patients with T2DM, ten studies reported the prognosis of COVID-19 in patients with sarcopenia, five studies discussed the outcomes of sarcopenia in patients with COVID-19, and one study reported sarcopenia outcomes in the presence of T2DM and COVID-19.

CONCLUSION

There is an obvious multidimensional relationship between T2DM, COVID-19 and sarcopenia which can cause prejudicial effects, poor prognosis, prolonged hospitalisation, lowered quality of life and a higher mortality rate during the current COVID-19 pandemic.

Functional fitness and risk factors of older patients with diabetes combined with sarcopenia and/or frailty: A cross-sectional study

AIM

To learn the functional fitness levels in older adults with diabetes combined with sarcopenia and/or frailty.

DESIGN

A cross-sectional investigation study.

METHODS

A total of 205 participants with type 2 diabetes were recruited from September 2019 to August 2020. All patients underwent diagnostic screening for sarcopenia and frailty, and were divided into combined group (the patients who had sarcopenia and/or frailty) and non-combined group (the patient who had no sarcopenia and/or frailty). The diagnostic criteria for sarcopenia applied was proposed by the Asian Working Group on Sarcopenia in 2019 and frailty status was assessed using FRAIL Scale. Functional fitness was measured using the Senior Fitness Test and compared between combined and non-combined groups. Biochemical data of blood routine, glycolipid, and hepatorenal function tests were acquired from medical records. Logistic regression analysis was applied to explore the factors associated with the sarcopenia and/or frailty in the older adults with diabetes.

RESULTS

Compared with non-combined group, the participants in combined group exhibited shorter 6-min walk distance, fewer repetitions of arm curls and chair stands, smaller back scratch and chair sit-and-reach values, and longer time in the 8-ft up-and-go test. The patients in the combined group had significantly lower level of red blood cell, haemoglobin, haematocrit, and higher level of platelet and blood urea nitrogen. Apart from calf circumference, physical activity, and insulin injection treatment, 6-min walk distance was the factor associated with diabetes combined with sarcopenia and/or frailty.

A comprehensive review on the risks assessment and treatment options for Sarcopenia in people with diabetes

Objectives

This comprehensive review aims to examine the reciprocal interplay between Type 2 diabetes mellitus (T2DM) and sarcopenia, identify prevailing research gaps, and discuss therapeutic approaches and measures to enhance healthcare practices within hospital settings.

Methods

A thorough literature review was conducted to gather relevant studies and articles on the relationship between T2DM and sarcopenia. Various databases were searched, including Google Scholar, PubMed, Scopus, and Science Direct databases. The search terms included T2DM, sarcopenia, inflammation, insulin resistance, advanced glycation end products, oxidative stress, muscle dimensions, muscle strength, muscle performance, aging, nutrition, hormone levels, and physical activity. The collected articles were critically analysed to extract key findings and identify gaps in current research.

Results

The prevalence and incidence of metabolic and musculoskeletal disorders, notably T2DM and sarcopenia, have surged in recent years. T2DM is marked by inflammation, insulin resistance, accumulation of advanced glycation end products, and oxidative stress, while sarcopenia involves a progressive decline in skeletal muscle mass and function. The review underscores the age-related correlation between sarcopenia and adverse outcomes like fractures, falls, and mortality. Research gaps regarding optimal nutritional interventions for individuals with T2DM and sarcopenia are identified, emphasizing the necessity for further investigation in this area.

Conclusions

The reciprocal interplay between T2DM and sarcopenia holds significant importance. Further research is warranted to address knowledge gaps, particularly in utilizing precise measurement tools during clinical trials. Lifestyle modifications appear beneficial for individuals with T2DM and sarcopenia. Additionally, practical nutritional interventions require investigation to optimize healthcare practices in hospital settings.

Prevalence of Sarcopenia and Dynapenia and Related Clinical Outcomes in Patients with Type 1 Diabetes Mellitus

BACKGROUND

Sarcopenia has recently been recognized as a complication of diabetes. However, there are few results about the prevalence of sarcopenia and dynapenia and the related clinical outcomes in type 1 diabetes mellitus (T1DM). Our objectives were to evaluate the prevalence of sarcopenia and dynapenia and to determine whether there are any associations with disease-related factors in people with T1DM.

METHODS

A cross-sectional study was conducted in people with T1DM. We assessed appendicular skeletal mass index (ASMI) using bioimpedance 50 Hz (Nutrilab Akern). Muscle function was assessed through handgrip strength (HGS) using a Jamar dynamometer. Sarcopenia was defined as a low HGS with low ASMI, whereas dynapenia was defined as low HGS with a normal ASMI. We used HGS data from the Spanish population percentile table and a cut-off point at p5 as dynapenia. The association of clinical, metabolic, and lifestyle variables with sarcopenia and dynapenia was studied.

RESULTS

This study included 62 T1DM patients (66% females, mean age of 38 ± 14 years, body mass index (BMI) of 24.9 ± 4.7 kg/m2). The prevalence of sarcopenia and dynapenia was 8% and 23%, respectively. In our sample, there were more men in the sarcopenic and dynapenic groups. The sarcopenic group showed a significantly higher mean HbA1c value. Lower diabetes duration, PREDIMED score, BMI, and muscle mass measures (fat-free mass index (FFMI), ASMI, and body cell mass index (BCMI)) were significantly associated with sarcopenia. Decreased diabetes duration, PREDIMED score, phase angle (PhA), and HGS values showed a significant association with dynapenia.

CONCLUSIONS

The prevalence of sarcopenia and dynapenia was high in people with T1DM in our study. Specifically, the proportion of dynapenia was quite high. HGS and ASMI are practical tools for the assessment of muscle health status in T1DM, and low values are associated with poor glycemic control, underweight, and low adherence to the Mediterranean diet. Thus, dynapenia may predict accelerated muscle aging in T1DM.

Cataract, glaucoma, and diabetic retinopathy are independent risk factors affecting falls in the older adult with eye diseases

OBJECTIVES

Falls are the leading cause of injury-related hospitalization in older adult, presenting a significant public health concern. To examine the specific eye diseases for risk factors of falls in the older adult.

METHODS

A total of 775 older adults admitted to tertiary care hospitals were divided into a fall or non-fall group based on a questionnaire. Logistic regression analysis was used to identify factors associated with falls.

RESULTS

With 208 falls, 775 participants were recruited. The major associated factors of falls were older age (Odds ratios [OR]: 1.05), female (OR: 1.91), cardiovascular diseases (OR: 1.65), more outdoor activities (OR: 2.81), cataract (OR: 1.65), glaucoma (OR: 1.63), diabetic retinopathy (OR: 2.72).

CONCLUSIONS

Our study demonstrates that cataract, glaucoma, and diabetic retinopathy in the older adult with eye diseases are independent risk factors of falls, which may shed light on the prevention of falls in the older adult with eye diseases.

Role of anti-vascular endothelial growth factor in the management of non-proliferative diabetic retinopathy without centre-involving diabetic macular oedema: a meta-analysis of trials

This systematic review and meta-analysis investigated the impact of anti-vascular endothelial growth factor (VEGF) treatment in management of eyes with non-proliferative diabetic retinopathy (NPDR) without centre involving diabetic macular oedema (CI-DMO). We searched multiple databases for all randomised clinical trials (RCTs) that evaluated anti-VEGF treatment versus observation in eyes with NPDR without CI-DMO. Data was collected for six outcomes (best corrected visual acuity (BCVA) improvement, diabetic retinopathy severity score (DRSS), central subfield thickness, progression to vision threatening complications (VTCs), ocular adverse events and quality of life measures). Risk of bias was assessed using Cochrane risk-of-bias tool for randomised trials (RoB 2) and certainty of evidence was assessed using Grade of Recommendations, Assessment, Development and Evaluation (GRADE). We identified a total of 2 unique RCTs that compared aflibercept and sham to treat a total of 811 eyes. For BCVA change, there was a small, clinically insignificant benefit for aflibercept treatment at year 2 (MD 0.70, 95% CI 0.02-1.38, GRADE rating: MODERATE). DRSS demonstrated a statistically significant improvement with aflibercept use at year 2 (RR 3.76, 95% CI 2.75-5.13, GRADE rating: MODERATE). VTCs were significantly less in aflibercept arm at year 2 (RR 0.30, 95% CI 0.23-0.40, GRADE rating: MODERATE). In conclusion, aflibercept treatment versus observation in eyes with NPDR without CI-DMO can result in reduced risk of development of VTCs and regression of DRSS score over 2 years. Future trials are needed to increase the precision of the treatment effect and to provide data on quality-of-life metrics.PROSPERO Registration: CRD42021288608.

Fractures and dislocations of the foot and ankle in people with diabetes: a literature review

Diabetes (DM) increases fracture risk, and bone quality depends on type diabetes type, duration, and other comorbidities. Diabetes is associated with a 32% increased relative risk (RR) of total fractures and 24% increased RR of ankle fractures compared with patients without DM. Type 2 DM is associated with a 37% increased RR of foot fractures compared with patients without DM. The incidence of ankle fractures in the general population is 169/100,000 per year, while foot fractures occur less frequently, with an incidence of 142/100,000 per year. Biomechanical properties of bone are negatively impacted by stiff collagen, contributing to the increased risk of fragility fractures in patients with DM. Systemic elevation of proinflammatory cytokines, such as tumor necrosis factor-alpha (TNFα), interleukin-1β (IL-1β), and interleukin 6 (IL-6), impact bone healing in patients with DM. Fractures in patients with DM, can be associated with poorly regulated levels of RANKL (receptor activator of nuclear transcription factor kappa-b ligand) leading to prolonged osteoclastogenesis, and net bone resorption. One of the most salient factors in treating fractures and dislocations of the foot and ankle is to recognize the difference between patients with uncomplicated and complicated DM. Complicated diabetes is defined as 'end organ damage', and for the purposes of this review, includes patients with neuropathy, peripheral artery disease (PAD) and/or chronic renal disease. Uncomplicated diabetes is not associated with 'end organ damage'. Foot and ankle fractures in patients with complicated DM pose challenges, and surgery is associated with increased risks of impaired wound healing, delayed fracture healing, malunion, infection, surgical site infection, and revision surgery. While patients with uncomplicated DM can be treated like patients without DM, patients with complicated DM require close follow-up and robust fixation methods should be considered to withstand the anticipated prolonged healing period. The aims of this review are as follows: (1) to review pertinent aspects of DM bone physiology and fracture healing, (2) to review the recent literature on treatment of foot and ankle fractures in patients with complicated DM, and (3) to provide treatment protocols based on the recent published evidence.

Incidence of accidental falls and development of a fall risk prediction model among elderly patients with diabetes mellitus: A prospective cohort study

AIMS

To investigate the incidence of accidental falls and develop a fall risk prediction tool in elderly patients with diabetes mellitus.

BACKGROUND

The risk of fall in elderly patients with diabetes is higher than that in the general elderly, there is fewer fall assessment tools for elderly patients with diabetes.

DESIGN

A prospective cohort study.

METHODS

Between June and September 2019, a total of 1007 elderly patients with diabetes were enrolled from a tertiary specialist diabetes hospital in Tianjin and were prospectively followed up for 6 months to determine outcomes of accidental falls through telephone. Demographic and diseases related factors were collected at baseline. Incidence of falls was investigated, and a nomogram was developed based on logistic regression model. SPSS 21.0 and R 3.6.3 were used to analyse the data. The article was reported in accordance with STROBE guidelines.

RESULTS

Among 1007 elderly patients, 950 finished the follow-up. A total of 133 falls occurred in 93 patients during the follow-up period, with a fall rate of 9.79%. Diabetic peripheral neuropathy, walking aids, depression, fall history, fatigue and sex were independent predictors of accidental fall in diabetes elderly patients. The sensitivity and specificity of the predictive model were 73.12% and 52.63%, respectively, and a fall risk prediction nomogram was developed based on the regression model.

CONCLUSIONS

A nomogram including 6 easily available prediction factors (diabetic peripheral neuropathy, walking aids, depression, fall history within 1 year, fatigue, sex) was developed, and it can be used in safety management among Chinese elderly patients diagnosed with diabetes.

RELEVANCE TO CLINICAL PRACTICE

Nomogram can be used to identify diabetic elderly patients at high risk of accidental falls.

Association of diabetes mellitus with gait and falls in community-dwelling older adults: Serial mediation of vision and cognition

BACKGROUND/OBJECTIVE

Diabetes mellitus (DM) is associated with walking performance, but potential underlying mechanisms of this association remain unclear. The present study aims to disentangle the pathways linking DM to gait and falls through the serial mediation effect of vision and cognition among the older population.

METHODS

Data were taken from wave 9 (2018-2019) of the English Longitudinal Study of Aging (ELSA), including 5496 participants aged 60 years and older. DM was identified based on medical diagnosis and laboratory tests. Vision and falls were self-reported. Cognition was evaluated using questionnaire. Gait speed was measured by the "timed walking test". Serial mediation analysis was performed using Mplus 8.3.

RESULTS

DM was associated with impaired gait speed (c = 0.085, P < 0.05) and falls (c = 0.061, P < 0.05). The serial mediation model revealed that vision and cognition significantly mediated the association of DM with impaired gait speed, with 17.97% and 23.60% of the total effects explained by vision and cognition respectively, and 3.37% explained by the path through vision and then cognition. Similarly, vision and cognition significantly mediated the association of DM with falls, with 14.99% and 6.67% of the total effects explained by vision and cognition respectively, and 1.67% explained by the path through vision and then cognition.

CONCLUSIONS

These findings contribute to deeper understanding of the mechanism underlying the association of DM with walking performance. Evaluation and intervention targeted at vision and the cognition may be beneficial for improving gait or reducing falls in older adults with DM.

Physiotherapists’ Perspectives on Type 2 Diabetes Management and as a Primary Condition for Referral to Physiotherapy Services: A Qualitative Descriptive Study

Purpose:

We explored the current and potential role of physiotherapists in the management of people with type 2 diabetes (T2D) and T2D as a primary condition for physiotherapy referral.

Method:

We conducted a qualitative descriptive study. Participants were physiotherapists practicing in community and outpatient settings across Canada. One-on-one telephone interviews were completed to explore provision of physiotherapy care for people with T2D, including current practices and readiness of physiotherapists to provide direct care. We employed thematic analysis for generation of themes from interviews.

Results:

We interviewed 21 participants from eight provinces and territories. Three themes were generated from the data: current approach to T2D management; challenges for physiotherapy integration; and merits of physiotherapy and needed evolution. Participants described that physiotherapists are not part of the healthcare team for T2D management. There is a gap in medical management of T2D that physiotherapy would fill, that is, education and prescription for exercise participation.

Conclusions:

Our findings support a gap in the management of T2D in Canadian healthcare, particularly in reference to physiotherapy. Further, our findings support the need for greater inclusion of physiotherapists for lifestyle counseling with an emphasis on physical activity and exercise for patients at risk of and with T2D to maximize health and improve/maintain function. Studies focusing on accessibility and funding of physiotherapy services are needed to validate these findings.

The association of glycemic control and fall risk in diabetic elderly: a cross-sectional study in Hong Kong

Background

Many foreign studies investigated glycemic control and fall risk. However, there was insufficient study on this topic in Hong Kong. This study aims to find out the association of glycemic control and fall risk in the diabetic elderly in a general outpatient clinic in the North District of Hong Kong. Their frequency of falls and other associated risk factors of fall were also studied.

Methods

A cross-sectional questionnaire survey was conducted on 442 diabetic patients aged 65 years-old or above with regular follow-up in a general outpatient clinic. Main outcome measure was the number of falls in the past one year from the interview date. Recurrent falls was defined as two or more falls in the past one year from the interview date. Subjects were asked about experience of hypoglycemic symptoms. HbA1c level, chronic illness, retinopathy etc. were obtained through computerized medical record review. Chi square test and logistic regression were used to assess the association between outcomes and the explanatory variables.

Results

In the past one year, 23.3% participants experienced at least one fall and 8.6% had recurrent falls. Hypoglycemic symptoms, and lower visual acuity < 0.6 were significantly associated with fall (OR 2.42, p = 0.007 and OR 1.75, p = 0.038 respectively). Age 75–79 years-old had a higher likelihood of fall than the 65–69 age group (OR 2.23, p = 0.044). Patients with HbA1c 7.0–7.4% had a lower risk of recurrent falls when compared to those with intensive control (OR 0.32, p = 0.044). Other risk factors that increased risk of recurrent falls were hypoglycemic symptoms (OR 6.64, p < 0.001) and history of cerebral vascular accident (OR 4.24, p = 0.003).

Conclusions

Hypoglycemic symptoms had a very strong association with falls. Less stringent HbA1c control reduced the risk of recurrent falls. Healthcare professionals need to take a more proactive approach in enquiring about hypoglycemia. There should be individualized diabetic treatment target for the diabetic elderly.

Sarcopenia and Chronic Complications of Type 2 Diabetes Mellitus

Sarcopenia, defined as the loss of skeletal muscle mass and strength and/or a decrease in physical performance, is classically related to aging. However, chronic disease, including type 2 diabetes mellitus (T2DM), may accelerate the development of sarcopenia. Previous studies found strong association between T2DM and sarcopenia. Insulin resistance that exists in T2DM is thought to be the key mediator for impaired physical function and mobility which may lead to sarcopenia. T2DM may cause sarcopenia through the mediation of insulin resistance, inflammation, accumulation of advanced glycation end-products, and oxidative stress that may affect muscle mass and strength, protein metabolism, and vascular and mitochondrial dysfunction. On the other hand, loss of muscle in sarcopenia may play a role in the development of T2DM through the decreased production of myokines that play a role in glucose and fat metabolism. This review highlights the findings of existing literature on the relationship between T2DM and sarcopenia which emphasize the pathophysiology, chronic vascular complications, and the course of macrovascular and microvascular complications in T2DM.

Diabetes and osteoporosis - Treating two entities: A challenge or cause for concern?

People with T1D and T2D have an increased risk of fractures than the general population, posing several significant pathophysiologic, diagnostic, and therapeutic challenges. The pathophysiology is still not fully elucidated, but it is considered a combination of increased skeletal fragility and falls. Diagnostics issues exist, as regular and even newer scan methods underestimate the true incidence of osteoporosis and thus the fracture risk. Therefore, co-managing diabetes and osteoporosis by using top-line strategies is essential to preserve bone health and minimize the risk of falls. The therapeutic focus should start with lifestyle implementation and physical exercise interventions to reduce diabetic complications, strengthen bones, and improve postural control strategies. In addition, osteoporosis should be treated according to current guidelines by including bisphosphonates and antidiabetic drugs that support bone health. Finally, potentially modifiable risk factors for falls should be managed.

The effects of exercise interventions on physical function tests and glycemic control in adults with type 2 diabetes: A systematic review

INTRODUCTION

Regular exercise improves glycemic control and helps to mitigate the decline in strength, mobility, and balance. The 6-min walk test (6MWT), timed up-and-go test (TUG) and the sit-to-stand test (STS) are reliable measures of physical function in adults with type 2 diabetes (T2D). Outcome measures allow physiotherapists to monitor changes in physical function with exercise prescription.

METHODS

PubMed, CINAHL, EMBASE and Scopus databases and reference lists of relevant reviews were searched for randomized controlled trials (RCTs) relating to exercise and T2D published until June 2020. Studies were included when: (a) participants were adults diagnosed with T2D, (b) exercise was a main intervention and compared to controls, and (c) at least one clinical physical function measure was used to detect changes in aerobic capacity, mobility or strength.

RESULTS

Eight of 10 RCTs reported either statistically significant between-group (p < 0.05) or within-group (p < 0.05) differences in 6MWT scores. Nonsignificant between-group differences were found in two resistance training RCTs that utilized the TUG test. Three of five RCTs utilizing the STS test reported significant between groups differences (p < 0.05). Seven of 11 RCTs reported statistically significant between-group (p < 0.05) or within-group (p < 0.05) differences in glycated hemoglobin (HbA1c) levels.

CONCLUSION

Physical function measures may be useful for monitoring aerobic capacity, lower extremity strength and mobility with exercise in patients with T2D. Improvements in 6MWT scores may depend on total volume of exercise (minutes/week ∗ weeks of intervention). However, changes in HbA1c with exercise were variable and may depend on type of exercise.

The Impact of Glucose-Lowering Drugs on Sarcopenia in Type 2 Diabetes: Current Evidence and Underlying Mechanisms

The age-related decrease in skeletal muscle mass together with the loss of muscle power and function is defined sarcopenia. Mounting evidence suggests that the prevalence of sarcopenia is higher in patients with type 2 diabetes mellitus (T2DM), and different mechanisms may be responsible for this association such as impaired insulin sensitivity, chronic hyperglycemia, advanced glycosylation end products, subclinical inflammation, microvascular and macrovascular complications. Glucose-lowering drugs prescribed for patients with T2DM might impact on these mechanisms leading to harmful or beneficial effect on skeletal muscle. Importantly, beyond their glucose-lowering effects, glucose-lowering drugs may affect per se the equilibrium between protein anabolism and catabolism through several mechanisms involved in skeletal muscle physiology, contributing to sarcopenia. The aim of this narrative review is to provide an update on the effects of glucose-lowering drugs on sarcopenia in individuals with T2DM, focusing on the parameters used to define sarcopenia: muscle strength (evaluated by handgrip strength), muscle quantity/quality (evaluated by appendicular lean mass or skeletal muscle mass and their indexes), and physical performance (evaluated by gait speed or short physical performance battery). Furthermore, we also describe the plausible mechanisms by which glucose-lowering drugs may impact on sarcopenia.

Reducing Fall Risks Among Visually Impaired Older Adults

Falls are the leading cause of death due to unintentional injuries in the older adult population, and fall-related death rates among older adults are escalating annually. Visual deficits are underrecognized and underdiagnosed, which increases fall risk. The purpose of this article is to provide a review of the common types of visual impairment, their etiology, and treatment and to present strategies to reduce falls among older adults with visual impairments. Both traditional home safety interventions and emerging technology-based interventions to reduce falls are described. Appropriate use of both traditional and emerging fall prevention interventions may reduce fall risk and falls among older adult home healthcare patients.

Risk of falls in 4 years of follow-up among Chinese adults with diabetes: findings from the China Health and Retirement Longitudinal Study

OBJECTIVES

This study was to determine the incidence of falls and identify baseline factors increased risk for incident falls over time among people with diabetes.

DESIGN

This study was a secondary analysis using the baseline and 4 years of follow-up data from the China Health and Retirement Longitudinal Study (CHARLS).

SETTING

A nationally representative survey of 17 500 Chinese residents aged 45 years and older were recruited in the baseline national survey in 2011. These participants were followed up every 2 years.

PARTICIPANTS

A total of 1238 middle-aged and older adults with diabetes and no history of falls at baseline were included in the current study.

PRIMARY AND SECONDARY OUTCOME MEASURES

Information on incidence of falls and medical treatment resulting from falls were determined by self-report.

RESULTS

The findings showed that the incidence of falls was 29.4% during 4 years of follow-up. Participants with incident falls were younger, were more likely to be women, had lower education level and were less likely to be current drinkers. In addition, former drinkers were 2.22 times more likely to fall. Socially active individuals were 47% less likely to fall compared with those without social activities. Every 5 kg increase in grip strength was associated with a 13% lower risk of falls. A 10 mg/dL higher total cholesterol and 1 mg/dL higher blood urea nitrogen were associated with a 4% and 6% higher risk of falls. Finally, participants with depressive symptoms were 1.47 times more likely to fall compared with those without depressive symptoms.

CONCLUSIONS

These findings underscore the importance of developing a fall prevention programme for those with diabetes, and this programme should address potentially modifiable risk factors, including levels of total cholesterol, blood urea nitrogen, social activity, depressive symptoms and grip strength.

Prevalence of bone fracture and its association with severe hypoglycemia in Japanese patients with type 1 diabetes

INTRODUCTION

Type 1 diabetes (T1D) is associated with higher fracture risk. However, few studies have investigated the relationship between severe hypoglycemia and fracture risk in patients with T1D, and the results are controversial. Besides, none has investigated the risk factors for fracture in Asian patients with T1D. The aim of the present study was to investigate the prevalence of bone fracture and its relationship between severe hypoglycemia and other risk factors in Japanese patients with T1D.

RESEARCH DESIGN AND METHODS

The single-center cross-sectional study enrolled 388 Japanese patients with T1D (mean age, 45.2 years; women, 60.4%; mean duration of diabetes, 16.6 years) between October 2019 and April 2020. The occurrence and circumstances of any fracture after the diagnosis of T1D were identified using a self-administered questionnaire. The main outcomes were any anatomic site of fracture and fall-related fracture. Severe hypoglycemia was defined as an episode of hypoglycemia that required the assistance of others to achieve recovery.

RESULTS

A total of 92 fractures occurred in 64 patients, and 59 fractures (64%) were fall-related. Only one participant experienced fracture within the 10 years following their diagnosis of diabetes. In logistic regression analysis, the multivariate-adjusted ORs (95% CIs) of a history of severe hypoglycemia were 2.11 (1.11 to 4.09) for any fracture and 1.91 (0.93 to 4.02) for fall-related fracture. Fourteen of 18 participants with multiple episodes of any type of fracture had a history of severe hypoglycemia (p<0.001 vs no fracture).

CONCLUSIONS

We have shown that a history of severe hypoglycemia is significantly associated with a higher risk of bone fracture in Japanese patients with T1D.

Sarcopenia Is Associated With Reduced Function on Admission to Rehabilitation in Patients With Diabetes

OBJECTIVE

This work aims to estimate the prevalence of sarcopenia and to investigate the association between sarcopenia and functional performance in patients with and without diabetes admitted for inpatient rehabilitation.

MATERIALS AND METHODS

Consecutive patients admitted to the subacute inpatient rehabilitation unit at St Vincent's Hospital Melbourne, Australia (November 2016 to March 2020) were prospectively recruited into this cross-sectional study. Sarcopenia was diagnosed using the European Working Group on Sarcopenia in Older People 2018 algorithm. Participants' functional performance was measured by the total Functional Independence Measure, motor Functional Independence Measure, and the Short Physical Performance Battery. The association between sarcopenia and functional performance was investigated using quantile regression.

RESULTS

Of 300 participants, 49 (16%) had a history of diabetes and 44 (14.7%) were diagnosed with sarcopenia. No significant difference in the prevalence of sarcopenia between patients with or without diabetes was identified (11/49, 22.5% vs 33/251, 13.2%, P = .12). In patients with diabetes, those with sarcopenia had significantly reduced functional performance compared to those without sarcopenia on Functional Independence Measure, motor Functional Independence Measure, and the Short Physical Performance Battery, whereas in patients without diabetes no significant difference between patients with and without sarcopenia were identified for either functional performance measure (all P values for interaction < .005).

CONCLUSIONS

The diagnosis of sarcopenia was associated with a reduced functional performance on admission to inpatient rehabilitation in patients with diabetes, but not in those without diabetes. Further investigation is needed into the progress of patients with dual diagnoses of diabetes and sarcopenia in inpatient rehabilitation.

A Narrative Review on Sarcopenia in Type 2 Diabetes Mellitus: Prevalence and Associated Factors

Type 2 diabetes mellitus (T2DM) represents a major health burden for the elderly population, affecting approximately 25% of people over the age of 65 years. This percentage is expected to increase dramatically in the next decades in relation to the increased longevity of the population observed in recent years. Beyond microvascular and macrovascular complications, sarcopenia has been described as a new diabetes complication in the elderly population. Increasing attention has been paid by researchers and clinicians to this age-related condition—characterized by loss of skeletal muscle mass together with the loss of muscle power and function—in individuals with T2DM; this is due to the heavy impact that sarcopenia may have on physical and psychosocial health of diabetic patients, thus affecting their quality of life. The aim of this narrative review is to provide an update on: (1) the risk of sarcopenia in individuals with T2DM, and (2) its association with relevant features of patients with T2DM such as age, gender, body mass index, disease duration, glycemic control, presence of microvascular or macrovascular complications, nutritional status, and glucose-lowering drugs. From a clinical point of view, it is necessary to improve the ability of physicians and dietitians to recognize early sarcopenia and its risk factors in patients with T2DM in order to make appropriate therapeutic approaches able to prevent and treat this condition.

Diabetes and Bone Fragility

Diabetes is a highly prevalent disease with complications that impact most bodily systems. However, the impact of diabetes on bone health is frequently ignored or underestimated. Both type 1 (T1D) and type 2 diabetes (T2D) are associated with a higher risk of fractures, albeit through different mechanisms. T1D is characterized by near total insulinopenia, which affects the anabolic tone of bone and results in reduced bone mineral density (BMD). Meanwhile, patients with T2D have normal or high BMD, but carry an increased risk of fractures due to alterations of bone microarchitecture and a local humoral environment that stimulates osteoclast activity. Chronic hyperglycemia induces non-enzymatic glycation of collagen in both types of diabetes. Epidemiological evidence confirms a largely increased fracture risk in T1D and T2D, but also that it can be substantially reduced by opportune monitoring of fracture risk and appropriate treatment of both diabetes itself and osteopenia or osteoporosis if they are present. In this review, we summarize the mechanistic, epidemiological, and clinical evidence that links diabetes and bone fragility, and describe the impact of available diabetes treatments on bone health.

Fear of Falling, Lower Extremity Strength, and Physical and Balance Performance in Older Adults with Diabetes Mellitus

Fear of falling (FoF) is known to affect the physical activities and quality of life of older adults with type 2 diabetes mellitus (DM). Many complications of DM, especially ones distressing lower extremity (LE), could lead to increased fall risk and FoF. This study aimed to explore the relationship between FoF, LE muscle strength, and physical performance in older adults without diabetes mellitus (ONDM) and with DM (ODM) with varying degrees of balance impairment. The participants comprised 20 ONDM and 110 ODM. The ODM was grouped by the number of failed performances of the modified clinical test of sensory interaction and balance (mCTSIB). The scores of FoF, balance performance of mCTSIB, physical performance of TUG, and LE muscle strength were compared between groups. The results showed that FoF was present in 30% and 60% of the ONDM and ODM, respectively. Forty percent of the ODM failed one condition of the mCTSIB, while 18% and 16% failed two and three conditions, respectively. As the number of failed performances on the mCTSIB increased, the proportions of participants with FoF significantly increased. The psychosocial domain of FoF, LE muscle strength, and TUG score was significantly different between groups and more affected in the ODM with a greater number of failed performances on the mCTSIB. In conclusion, the mCTSIB can differentiate the varying degrees of balance impairment among ODM. FoF, LE muscle strength, and physical performance are more affected as the degree of balance impairment increases. Comprehensive management related to balance and falls in the ODM should include a regular evaluation and monitoring of standing balance, LE muscle strength, physical performance, and FoF.

Falls and Fractures in Diabetes-More than Bone Fragility

PURPOSE OF REVIEW

Based on a systematic literature search, we performed a comprehensive review of risk factors for falls and fractures in patients with diabetes.

RECENT FINDINGS

Patients with diabetes have an increased risk of fractures partly explained by increased bone fragility. Several risk factors as altered body composition including sarcopenia and obesity, impaired postural control, gait deficits, neuropathy, cardiovascular disease, and other co-morbidities are considered to increase the risk of falling. Diabetes and bone fragility is well studied, but new thresholds for fracture assessment should be considered. In general, the risk factors for falls in patients with diabetes are well documented in several studies. However, the fall mechanisms among diabetic patients have only been assessed in few studies. Thus, a gab of knowledge exits and may influence the current understanding and treatment, in order to reduce the risk of falling and thereby prevent fractures.

Sarcopenia and type 2 diabetes mellitus: a bidirectional relationship

The incidence and prevalence of metabolic and musculoskeletal diseases are increasing. Type 2 diabetes mellitus (T2DM) is characterized by insulin resistance, inflammation, advanced glycation end-product accumulation and increased oxidative stress. These characteristics can negatively affect various aspects of muscle health, including muscle mass, strength, quality and function through impairments in protein metabolism, vascular and mitochondrial dysfunction, and cell death. Sarcopenia is a term used to describe the age-related loss in skeletal muscle mass and function and has been implicated as both a cause and consequence of T2DM. Sarcopenia may contribute to the development and progression of T2DM through altered glucose disposal due to low muscle mass, and also increased localized inflammation, which can arise through inter- and intramuscular adipose tissue accumulation. Lifestyle modifications are important for improving and maintaining mobility and metabolic health in individuals with T2DM and sarcopenia. However, evidence for the most effective and feasible exercise and dietary interventions in this population is lacking. In this review, we discuss the current literature highlighting the bidirectional relationship between T2DM and sarcopenia, highlight current research gaps and treatments, and provide recommendations for future research.

Type 1 Diabetes and Bone Fragility: Links and Risks

Type 1 diabetes (T1D) is associated with an increased fracture risk, which is present at young and old age. Reductions in bone mineral density do not explain the increased fracture risk. Novel scanning modalities suggest that structural deficits may contribute to the increased fracture risk. Furthermore, T1D may due to insulinopenia be a state of low bone turnover. However, diabetes complications and comorbidities may influence fracture risk. Patients with T1D are fearful of falls. The diabetes related complications, hypoglycemic events, and antihypertensive treatment may all lead to falls. Thus, the increased fracture risk in T1D seems to be multifactorial, and earlier intervention with antiosteoporotic medication and focus on fall prevention is needed. This systematic review addresses the epidemiology of fractures and osteoporosis in patients with T1D and the factors that influence fracture risk.

Prevalence and association of clinical characteristics and biochemical factors with complications of diabetes mellitus in Palestinians treated in primary healthcare practice

AIMS

The current study was carried out to examine prevalence of complications related to diabetes mellitus (DM) and to investigate association between clinical variables and biochemical factors with complications of DM in patients treated in primary healthcare settings in the West Bank of Palestine.

MATERIALS AND METHODS

Sociodemographic, clinical, and biochemical variables were collected from 385 patients visiting 17 primary healthcare settings in the West Bank. Patients provided blood and urine samples, responded to a questionnaire interview, and were subjected to ophthalmic examination.

RESULTS

HbA_1c levels were predicted by duration of DM (p < 0.001), HDL (p = 0.011), alkaline phosphatase (p = 0.001), blood urea (p = 0.006), and LDL (p = 0.008). Triglycerides levels were predicted by blood urea (p = 0.002), HDL (p < 0.001), and total cholesterol (p < 0.001). GOT levels were predicted by LDL (p = 0.002) and GPT (p < 0.001). GPT levels were predicted by HDL (p = 0.003) and blood urea (p = 0.025). Urine albumin were predicted by total cholesterol (p = 0.001), LDL (p = 0.005), and blood urea (p = 0.036). CD ratio was predicted by the IOP and the IOP was predicted by the CD ratio (p = 0.001).

CONCLUSIONS

Prevalence of complications related to DM was high among patients with DM treated in primary healthcare practice. These complications and risk factors were predicted by certain clinical characteristics and biochemical factors. Policies and programs are needed to manage these modifiable risk factors.
