The Finnish Diabetes Risk Score is associated with insulin resistance and progression towards type 2 diabetes

No clear evidence of neuropathy among patients with high risk for the development of prediabetes/diabetes-a pilot study

Introduction

Autonomic and sensory neuropathy have been observed in both prediabetes and manifest diabetes mellitus. However, there is a lack of available data regarding whether patients at a moderate or high risk of developing diabetes, yet without a current diagnosis of prediabetes or diabetes, exhibit an increased prevalence of neuropathy.

Methods

FINDRISC (Finnish Diabetes Risk Score) was used to classify individuals at risk (≥12 points, n = 44; control <12 points, n = 28). HbA1c levels >5.6% served as exclusion criteria, and patients with known medical conditions predisposing to neuropathy were also excluded. Cardiac autonomic function (Ewing tests) and peripheral sensory neuropathy (Neurometer and Q-sense) were assessed by standardized protocols, and their potential association with increased FINDRISC points was analyzed using a regression model.

Results

Mean age was 46.7 ± 14.3 years in the control and 55.7 ± 14.1 years in the increased risk group. Male/female ratio did not differ. Individuals with increased risk of diabetes were more obese (BMI: 29.9 ± 12.5 kg/m2 vs. 25.9 ± 8.9 kg/m2). Additionally, hypertension was more frequent among them (68.2% vs. 17.9%), and their lipid parameters were also less favorable. Parasympathetic neuropathy was present in both groups (56.8% vs. 32.1%, respectively). Sympathetic neuropathy was not found. Sensory nerve dysfunction was of low prevalence in the high-risk group and did not occur in healthy controls. In multiple logistic regression analysis, HbA1c exhibited an independent association with parasympathetic neuropathy (OR: 5.9; 95% CI: 1.08-32.68; p < 0.041).

Discussion

An increased risk of developing prediabetes/diabetes does not appear to have a strong correlation with an increased likelihood of developing autonomic or sensory neuropathy. However, the etiology behind the occurrence of parasympathetic autonomic neuropathy in healthy individuals remains unknown.

An Assessment of the 10-Year Risk of Developing Type 2 Diabetes Among Saudi Adults Based on the Finnish Diabetes Risk Score

Background and objective

Diabetes mellitus (DM) is a chronic, metabolic disease characterized by elevated blood glucose levels that eventually lead to several acute and chronic complications. Type 2 DM (T2DM) is a major healthcare problem globally as well as in the Kingdom of Saudi Arabia (KSA). Predicting and identifying people at high risk for developing T2DM will help implement preventive measures for these individuals. In light of this, the present study was designed to estimate the 10-year risk of developing T2DM among the Saudi general population.

Methodology

A descriptive, cross-sectional survey involving 15,509 Saudi individuals was undertaken. The participants were selected from all 13 provinces of KSA based on stratified random sampling. The Finnish Diabetes Risk Score (FINDRISC), a validated tool for T2DM risk assessment, was employed. Descriptive and chi-square analyses were used.

Results

The mean age of the participants was 28.33 years. Subjects with a moderate, high, and very high risk of developing T2DM within the next 10 years comprised approximately 18% of the sample. The mean FINDRISC was 7.53 [standard deviation (SD): 4.28], which is considered a level associated with a slightly elevated risk of developing T2DM. Of note, 938 participants (6.05%) among the sample population had a high risk of developing T2DM as predicted by FINDRISC. Education, daily physical activity, high blood glucose, and family history of DM were significantly higher in females compared to males (p<0.001). On the other hand, smoking rates and use of antihypertensive medications were substantially higher among males (p<0.001).

Conclusion

Based on our findings, approximately 18% of the Saudi general population has a moderate to high risk of developing T2DM. T2DM risk assessment should be widely and regularly practiced by general practitioners and internists as part of national programs for diabetes prevention.

Continuous glycemia monitoring in perioperative period in patients undergoing total knee or hip arthroplasty: A protocol for a prospective observational study

In every surgical subspecialty surgical site infection (SSI) or implant infections, although occur seldom, pose a threat to patients' health. Risk factors of such states is diabetes mellitus (DM), considered one of the most widespread health-related problems of the 21st century. Orthopedists perform big joint replacements that usually concern older adults and therefore often deal with patients suffering from comorbidities. DM is frequently one of them and can furthermore often remain underdiagnosed. The other risk for complication is a rapid beginning of the rehabilitation which starts on the day following the surgery. To eliminate the debilitating impact of DM and hypoglycemia on surgical patients, we aim to investigate the relationship between the glycemia values and the postoperative outcomes in certain periods of time in patients undergoing orthopedic surgeries. Participants meeting inclusion criteria will have inserted a glycemia measuring device (Dexcom G5, Inc., San Diego, CA) in the periods of time. First time it will take place 14 days prior to the surgery and right after the surgery for the second time for the period of another 14 days. All patients will undergo standard total knee arthroplasty or total hip arthroplasty procedures. Patients will be assessed preoperatively and 14 days, 1, 3, 6, 12, and 24 months postoperatively. The assessment of the joint condition will consist of: patient-reported outcomes (The Knee injury and Osteoarthritis Outcome Score, Harris Hip Score, the Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]); assessment of potential SSI and cardiovascular complications (the Finnish Diabetes Risk Score [FINDRISC], the Systematic Coronary Risk Evaluation [SCORE]) and the clinical examination. To investigate the influence of orthopedic surgery (anesthesia) on glycemia and the significance and safety of early patients mobilization after the big joints surgeries. To investigate changes of glycemia in patients with normal glycemia metabolism, potentially protecting them from hypoglycemia during hospital stay and increasing their awareness of potential development of DM in the future. Additionally, this study will correlate perioperative glycemic levels with risk of cardiovascular events in one year follow-up, and its influence on SSI and implant complications.

Non-invasive type 2 diabetes risk scores do not identify diabetes when the cause is β-cell failure: The Africans in America study

Background

Emerging data suggests that in sub-Saharan Africa β-cell-failure in the absence of obesity is a frequent cause of type 2 diabetes (diabetes). Traditional diabetes risk scores assume that obesity-linked insulin resistance is the primary cause of diabetes. Hence, it is unknown whether diabetes risk scores detect undiagnosed diabetes when the cause is β-cell-failure.

Aims

In 528 African-born Blacks living in the United States [age 38 ± 10 (Mean ± SE); 64% male; BMI 28 ± 5 kg/m²] we determined the: (1) prevalence of previously undiagnosed diabetes, (2) prevalence of diabetes due to β-cell-failure vs. insulin resistance; and (3) the ability of six diabetes risk scores [Cambridge, Finnish Diabetes Risk Score (FINDRISC), Kuwaiti, Omani, Rotterdam, and SUNSET] to detect previously undiagnosed diabetes due to either β-cell-failure or insulin resistance.

Methods

Diabetes was diagnosed by glucose criteria of the OGTT and/or HbA1c ≥ 6.5%. Insulin resistance was defined by the lowest quartile of the Matsuda index (≤ 2.04). Diabetes due to β-cell-failure required diagnosis of diabetes in the absence of insulin resistance. Demographics, body mass index (BMI), waist circumference, visceral adipose tissue (VAT), family medical history, smoking status, blood pressure, antihypertensive medication, and blood lipid profiles were obtained. Area under the Receiver Operator Characteristics Curve (AROC) estimated sensitivity and specificity of each continuous score. AROC criteria were: Outstanding: >0.90; Excellent: 0.80-0.89; Acceptable: 0.70-0.79; Poor: 0.50-0.69; and No Discrimination: 0.50.

Results

Prevalence of diabetes was 9% (46/528). Of the diabetes cases, β-cell-failure occurred in 43% (20/46) and insulin resistance in 57% (26/46). The β-cell-failure group had lower BMI (27 ± 4 vs. 31 ± 5 kg/m² P < 0.001), lower waist circumference (91 ± 10 vs. 101 ± 10cm P < 0.001) and lower VAT (119 ± 65 vs. 183 ± 63 cm³, P < 0.001). Scores had indiscriminate or poor detection of diabetes due to β-cell-failure (FINDRISC AROC = 0.49 to Cambridge AROC = 0.62). Scores showed poor to excellent detection of diabetes due to insulin resistance, (Cambridge AROC = 0.69, to Kuwaiti AROC = 0.81).

Conclusions

At a prevalence of 43%, β-cell-failure accounted for nearly half of the cases of diabetes. All six diabetes risk scores failed to detect previously undiagnosed diabetes due to β-cell-failure while effectively identifying diabetes when the etiology was insulin resistance. Diabetes risk scores which correctly classify diabetes due to β-cell-failure are urgently needed.

Characteristic of FINDRISC Score and Association with Diabetes Development in 6-Year Follow-Up in PURE Poland Cohort Study

Purpose

The aim of the study was to assess if FINDRISC score was associated with diabetes development after 6 years of observation.

Methods

Polish cohort is a part of global PURE study. Hereby analysis presents data from baseline (2007–2010) and 6-year follow-up (2013–2016) and was conducted on 1090 participants (702 women) from urban and rural areas in Lower Silesia region (Poland) without diabetes at the baseline and with complete data throughout course of the study.

Results

At the baseline, women had significantly higher FINDRISC score than men (10.43 vs 8.91; p=0.000) and participants from rural areas had higher score than from urban areas (10.97 vs 9.33; p=0.000). At the baseline, 25.87% of the participants had low risk of diabetes according to FINDRISC score, 38.90% had slightly elevated risk, 16.79% moderate risk, 16.42% high risk and 2.02% very high risk. Participants, who were healthy at baseline, but developed diabetes after 6 years of observation had significantly higher FINDRISC, than those who did not (13.39 vs 9.36; p=0.000). In 6-year follow-up, diabetes was diagnosed in 2.8% of participants, who were ascertained to “low risk” according to FINDRISC score in baseline; in 9.9% of participants of “slightly elevated risk”, 17.5% of participants of “moderate risk”, 26.8% in participants of “high risk” and 50.0% of participants of “very high risk”.

Conclusions

Results of PURE Poland cohort study indicates that higher FINDRISC score at the baseline was associated with higher risk of diabetes development during 6 years of observation.

Nomogram Predicting the Risk of Progression from Prediabetes to Diabetes After a 3-Year Follow-Up in Chinese Adults

PURPOSE

To develop a nomogram for predicting the risk of progression from prediabetes to diabetes and provide a quantitative predictive tool for early clinical screening of high-risk populations of diabetes.

MATERIALS AND METHODS

This study was a retrospective cohort study and part of the investigation conducted for the Risk Evaluation of cAncers in Chinese diabeTic Individuals: a lONgitudinal (REACTION) study. A total of 1857 prediabetic participants at baseline underwent oral glucose tolerance test and hemoglobin A1c (HbA1c) testing after 3 years. The areas under the receiver operating characteristic curves (AUCs) were adopted to measure the predictive value of progression to diabetes, using baseline fasting plasma glucose (FPG), 2-hr postprandial plasma glucose (2hPG), HbA1c or combined models. Decision curve analysis determined the model with the best discriminative ability. A nomogram was formulated and internally validated, providing an individualized predictive tool by calculating total scores.

RESULTS

After 3 years, 145 participants developed diabetes, and the annual incidence was estimated to be 2.60%. Among the three single indicators and four combined models, model 4 combined of FPG, 2hPG, and HbA1c showed the best performance in risk predication, with an AUC of 0.742. The nomogram constructed via model 4 was validated and demonstrated good prediction for the risk of diabetes. The nomogram score/predicted probability was a numeric value representing the prediction model score of individual patients. Notably, all nomogram scores showed relatively high negative predictive values.

CONCLUSION

The nomogram constructed in this study effectively predicts and quantifies the risk of progression from prediabetes to diabetes after a 3-year follow-up and could be adopted to identify Chinese patients at high risk for diabetes in order to provide timely interventions.

The Finnish Diabetes Risk Score (FINDRISC), incident diabetes and low-grade inflammation

AIMS

The FINDRISC was created to predict the development of type 2 diabetes mellitus (T2DM). Since T2DM associates with inflammation we evaluated if the FINDRISC could predict either current or incident T2DM, and elevated high sensitivity C-reactive protein (hs-CRP).

METHODS

41,880 people (age 41.9 ± 9.7 years; 31% female) evaluated between 2008 and 2016 were included. First, the cross-sectional association between the FINDRISC with presence of either T2DM or hs-CRP ≥ 2.0 mg/L was tested. After a 5 ± 3 years follow-up we tested the score predictive value for incident T2DM and inflammation in respectively 10,559 individuals without diabetes and in a subset of 2,816 individuals having no elevated hs-CRP at baseline.

RESULTS

In the cross sectional analysis the FINDRISC was associated with both T2DM (OR 1.24, 95% CI: 1.23-1.26, P < 0.001) and inflammation (OR 1.10, 95% CI: 1.09-1.11, P < 0.001) per FINDRISC unit, as well as in longitudinal analyses (OR 1.17, 95% CI: 1.14-1.20, P < 0.001; and OR 1.04, 95% CI: 1.02-1.07, P < 0.001; respectively, per FINDRISC unit). The C-statistic for incident T2DM and inflammation was 0.79 (95% CI 0.77-0.82) and 0.55 (95% CI 0.53-0.58), respectively.

CONCLUSION

The FINDRISC shows good discrimination for incident T2DM but less for inflammation.

A Diet-Dependent Microbiota Profile Associated with Incident Type 2 Diabetes: From the CORDIOPREV Study

SCOPE

The differences between the baseline gut microbiota of patients who developed type 2 diabetes (T2D) consuming a low-fat (LF) or a Mediterranean (Med) diet are explored and risk scores are developed to predict the individual risk of developing T2D associated with the consumption of LF or Med diet.

METHODS AND RESULTS

All the patients from the CORDIOPREV study without T2D at baseline (n = 462) whose fecal sample are available, are included. Gut microbiota is analyzed by 16S sequencing and the risk of T2D after a median follow-up of 60 months assessed by Cox analysis. Linear discriminant analysis effect size (LEfSe) analysis shows a different baseline gut microbiota in patients who developed T2D consuming LF and Med diets. A higher abundance of Paraprevotella, and lower Gammaproteobacteria and B. uniformis are associated with T2D risk when an LF diet is consumed. In contrast, higher abundances of Saccharibacteria, Betaproteobacteria, and Prevotella are associated with T2D risk when a Med diet is consumed.

CONCLUSION

The results suggest that different interactions between the microbiome and dietary patterns may partially determine the risk of T2D development, which may be used for selecting personalized dietary models to prevent T2D.

Risk and management of pre-diabetes

Type 2 diabetes mellitus (T2DM) is associated with a two- to four-fold increased risk of developing cardiovascular disease (CVD) and microvascular complications, which may already be present before diagnosis. It is, therefore, important to detect people with an increased risk of T2DM at an early stage. In order to identify individuals with so-called 'pre-diabetes', comprising impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), current guidelines have developed definitions based on fasting plasma glucose, two-hour glucose concentrations and haemoglobin A1c. Subjects with pre-diabetes are at an increased risk of developing T2DM and CVD. This elevated risk seems similar according to the different criteria used to define pre-diabetes. The risk of progression to T2DM or CVD does, however, depend on other risk factors such as sex, body mass index and ethnicity. Based on the risk factors to develop T2DM, many risk assessment models have been developed to identify those at highest risk. These models perform well to identify those at risk and could be used to initiate preventive interventions. Many studies have shown that lifestyle modification and metformin are effective in preventing the development of T2DM, although lifestyle modification seems to have a more sustainable effect. In addition, lifestyle modification seems more effective in those with IGT than those with IFG. In this review, we will describe the different definitions used to define pre-diabetes, progression from pre-diabetes to T2DM or other vascular complications, risk factors associated with progressions and the management of progression to T2DM, ending with clinical recommendations.

[Quality of Life and Satisfaction During the Diabetes Prevention Program GLICEMIA: a Cluster-Randomized, Controlled Trial]

OBJECTIVES

We aimed to assess the health-related quality of life as well as participant satisfaction during the pharmacy-based diabetes prevention program GLICEMIA.

METHODS

GLICEMIA comprises 3 individual counseling sessions and 5 group-based lectures addressing a lifestyle modification. In a cluster-randomized controlled trial, GLICEMIA was compared with reduced standard information in the control group. After 12 months, the groups were compared regarding the diabetes risk score FINDRISC, health-related quality of life with the 12-item Short Form health survey (SF-12) and participant satisfaction.

RESULTS

In total, the data of 1,087 participants were analyzed. During GLICEMIA, 38.9% reduced their FINDRISC whereas 20.9% reached this goal in the control group. Moreover, the physical quality of life improved significantly in the intervention group compared with the control group (adjusted effect size: 2.39 points, 95% CI 1.43-3.34). Participants of GLICEMIA who reduced their diabetes risk had enhanced mental and physical quality of life after one year. This was not observed in the control group. The overall benefit and satisfaction were rated very high in the intervention group.

CONCLUSION

Participation in GLICEMIA results in a significant reduction of the diabetes risk according to the FINDRISC, as well as an improved physical and mental quality of life. The high satisfaction of the participants reflects the overall benefit. Nationwide implementation of the program is recommended.

Diagnostic accuracy of the Finnish Diabetes Risk Score (FINDRISC) for undiagnosed T2DM in Peruvian population

AIMS

To assess the diagnostic accuracy of the Finnish Diabetes Risk Score (FINDRISC) for undiagnosed T2DM and to compare its performance with the Latin-American FINDRISC (LA-FINDRISC) and the Peruvian Risk Score.

MATERIALS AND METHODS

A population-based study was conducted. T2DM and undiagnosed T2DM were defined using oral glucose tolerance test (OGTT). Risk scores assessed were FINDRISC, LA-FINDRISC and Peruvian Risk Score. Diagnostic accuracy of risk scores was estimated using the c-statistic and the area under the ROC curve (aROC). A simplified version of FINDRISC was also derived.

RESULTS

Data from 1609 individuals, mean age 48.2 (SD: 10.6), 810 (50.3%) women, were collected. A total of 176 (11.0%; 95%CI: 9.4%-12.5%) were classified as having T2DM, and 71 (4.7%; 95%CI: 3.7%-5.8%) were classified as having undiagnosed T2DM. Diagnostic accuracy of the FINDRISC (aROC=0.69), LA-FINDRISC (aROC=0.68), and Peruvian Risk Score (aROC=0.64) was similar (p=0.15). The simplified FINDRISC, with 4 variables, had a slightly better performance (aROC=0.71) than the other scores.

CONCLUSION

The performance of FINDRISC, LA-FINDRISC and Peruvian Risk Score for undiagnosed T2DM was similar. A simplified FINDRISC can perform as well or better for undiagnosed T2DM. The FINDRISC may be useful to detect cases of undiagnosed T2DM in resource-constrained settings.

Detecting persons at risk for diabetes mellitus type 2 using FINDRISC: results from a community pharmacy-based study

Background

This cross-sectional study has been developed within the framework of the Italian project 'We love your heart' ('Ci sta a cuore il tuo cuore') and reports the results of the initial type 2 diabetes mellitus (T2DM) risk assessment carried out in a big network of community pharmacies in Italy and Spain.

Methods

In total 4002 pharmacists from 854pharmacies were specifically trained to collect data and perform the evaluation of the probability of developing T2DM among pharmacy customers. The risk of developing T2DM within 10 years was evaluated using the FINDRISC.

Results

Overall, 7234 (22.1%) subjects were at low risk to develop the disease, whereas 43.3% were at slightly elevated risk (scores 7-11), 19.3% were at moderate (scores 12-14), 13.9% were at high (scores 15-20), and 1.4% were at very high risk (scores > 20). Spanish participants showed higher levels of risk than Italian (16.7 vs. 14.7%) taking the cut-off FINDRISC ≥ 15.

Conclusion

This study shows that considerable percentage of persons is likely to develop diabetes in the next 10 years. Analyses of the risk factors indicate that men were more susceptible to develop this disease, as well as the Spanish participants respect to Italian.

Epicardial adipose tissue thickness and type 2 diabetes risk according to the FINDRISC modified for Latin America

BACKGROUND

The Finnish Diabetes Risk Score (FINDRISC) is a tool to predict 10-year risk of type 2 diabetes mellitus (T2DM), and visceral adiposity is associated with higher cardio-metabolic risk. The objective of the study was to assess the relationship of epicardial adipose tissue (EAT) thickness with T2DM risk according to the FINDRISC tool.

METHODS

The study was conducted in Ciudad Bolívar, Venezuela, and included 55 subjects of whom 37 (67.3%) were women and 18 (32.7%) men with ages between 18 and 75 years. A record was made of weight, height, body mass index (BMI), waist circumference (WC), fasting glucose, baseline insulin, plasma lipids, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR), and EAT thickness. The FINDRISC tool, with WC cut-off points modified for Latin America (LA-FINDRISC) was used.

RESULTS

BMI, WC, plasma insulin concentration, HOMA-IR index, and EAT thickness were higher (P<0.0001) in the high-risk group compared to subjects in the low-moderate risk group according to the LA-FINDRISC. LA-FINDRISC was positively correlated with BMI (r=0.513; P=0.0001), WC (r=0.524; P=0.0001), fasting blood glucose (r=0.396; P=0.003); baseline plasma insulin (r=0.483; P=0.0001); HOMA-IR index (r=0.545; P=.0.0001); and EAT thickness (r=0.702; P=0.0001). The multivariate regression analysis showed that fasting blood glucose (P=0.023) and EAT thickness (P=0.007) remained independently associated with high T2DM risk.

CONCLUSIONS

LA-FINDRISC was associated with EAT thickness and insulin resistance markers. Both were independently and directly associated with high risk for diabetes in the LA-FINDRISC category.

Undetected dysglycaemia common in primary care patients treated for hypertension and/or dyslipidaemia: on the need for a screening strategy in clinical practice. A report from EUROASPIRE IV a registry from the EuroObservational Research Programme of the European Society of Cardiology

Background

Dysglycaemia defined as type 2 diabetes (T2DM) and impaired glucose tolerance (IGT), increases the risk of cardiovascular disease (CVD). The negative impact is more apparent in the presence of hypertension and/or dyslipidaemia. Thus, it seems reasonable to screen for dysglycaemia in patients treated for hypertension and/or dyslipidaemia. A simple screening algorithm would enhance the adoption of such strategy in clinical practice.

Objectives

To test the hypotheses (1) that dysglycaemia is common in patients with hypertension and/or dyslipidaemia and (2) that initial screening with the Finnish Diabetes Risk Score (FINDRISC) will decrease the need for laboratory based tests.

Methods

2395 patients (age 18–80 years) without (i) a history of CVD or TDM2, (ii) prescribed blood pressure and/or lipid lowering drugs answered the FINDRISC questionnaire and had an oral glucose tolerance test (OGTT) and HbA1c measured.

Results

According to the OGTT 934 (39%) had previously undetected dysglycaemia (T2DM 19%, IGT 20%). Of patients, who according to FINDRISC had a low, moderate or slightly elevated risk 20, 34 and 41% and of those in the high and very high-risk category 49 and 71% had IGT or T2DM respectively. The OGTT identified 92% of patients with T2DM, FPG + HbA1c 90%, FPG 80%, 2hPG 29% and HbA1c 22%.

Conclusions

(1) The prevalence of dysglycaemia was high in patients treated for hypertension and/or dyslipidaemia. (2) Due to the high proportion of dysglycaemia in patients with low to moderate FINDRISC risk scores its initial use did not decrease the need for subsequent glucose tests. (3) FPG was the best test for detecting T2DM. Its isolated use is limited by the inability to disclose IGT. A pragmatic strategy, decreasing the demand for an OGTT, would be to screen all patients with FPG followed by OGTT in patients with IFG.

The impact of pancreaticoduodenectomy on endocrine and exocrine pancreatic function: A prospective cohort study based on pre- and postoperative function tests

BACKGROUND/OBJECTIVES

Studies reporting on function after pancreatic surgery are frequently based on diabetes history, fasting glycemia or random glycemia. The aim of this study was to investigate prospectively the evolution of pancreatic function in patients undergoing pancreaticoduodenectomy based on proper pre- and postoperative function tests. It was hypothesised that pancreatic function deteriorates after pancreaticoduodenectomy.

METHODS

Between 2013 and 2016, 78 patients undergoing pancreaticoduodenectomy for oncologic indications had a prospective evaluation of their endocrine and exocrine pancreatic function. Endocrine function was evaluated with the 75 g oral glucose tolerance test (OGTT) and the 1 mg intravenous glucagon test. Exocrine function was evaluated with a 13C-labelled mixed-triglyceride breath test. Tests were performed pre- and postoperatively.

RESULTS

In 90.5% (19/21) of patients with preoperatively known diabetes, no change in endocrine function was observed. In contrast, endocrine function improved in 68.1% (15/22) of patients with newly diagnosed diabetes. 40% (14/35) of patients with a preoperative normal OGTT or prediabetes experienced deterioration in function. In multivariate analysis, improvement of newly diagnosed diabetes was correlated with preoperative bilirubin levels (p = 0.045), while progression towards diabetes was correlated with preoperative C-peptidogenic index T₃₀ (p = 0.037). A total of 20.5% (16/78) of patients had pancreatic exocrine insufficiency preoperatively. Another 51.3% (40/78) of patients deteriorated on exocrine level. In total, 64.1% (50/78) of patients required pancreatic enzyme-replacement therapy postoperatively.

CONCLUSIONS

Although deterioration of endocrine function was expected after pancreatic resection, improvement is frequently observed in patients with newly diagnosed diabetes. Exocrine function deteriorates after pancreaticoduodenectomy.

Signs of subclinical atherosclerosis in asymptomatic patients at increased risk of type 2 diabetes mellitus

AIMS

We aimed to study carotid intima media thickness (CIMT) in asymptomatic patients with an increased risk of type 2 diabetes mellitus (T2DM) and in a pre-diabetic state.

METHODS

Diabetes risk assessment was performed in 2420 participants in a voluntary screening program between 2011 and 2013. The risk of T2DM was estimated by the Findrisc scoring system (FR). A FR≥12 was considered as increased risk. HbA1c% between 5.7 and 6.4% signified a pre-diabetic state. Carotid duplex scan was performed and CIMT above 0.9 mm was regarded as pathological. Patients with T2DM or a history of cardiovascular disease were excluded.

RESULTS

Overall 1475 subjects were included. Four groups were compared: "control" (normal HbA1c, FR<12), "HbA1c only" (HbA1c: 5.7-6.4%, FR<12), "Findrisc only" (normal HbA1c, FR≥12) and "combined" (HbA1c: 5.7-6.4%, FR≥12). Frequency of pathological maximal CIMT was 9.4%, 19.7%, 27.4% and 36.4% in the groups, respectively (p<0.001). Logistic regression analysis revealed that compared to control subjects, sex and risk factor-adjusted Odds Ratios for the presence of pathological maximal CIMT were 2.2 (p<0.001), 3.4 (p<0.001) and 5.1 (p<0.001) for the groups, respectively.

CONCLUSIONS

Evaluation of Findrisc score and HbA1c at population level may facilitate early recognition of subclinical vascular complications even in the pre-diabetic state.

Relationship between the Finnish Diabetes Risk Score (FINDRISC), vitamin D levels, and insulin resistance in obese subjects

AIM

To assess the relationship between 25-hydroxyvitamin D [25(OH)D] blood concentrations in subjects with obesity and type 2 diabetes mellitus (T2D) risk according to the Finnish Diabetes Risk Score (FINDRISC) modified for Latin America (LA-FINDRISC).

METHODS

This study was conducted in Ciudad Bolívar, Venezuela. Eighty two women and 20 men (53 obese and 49 nonobese), with an average age of 42.6±12.30 years were enrolled. Weight, height, body mass index (BMI), waist circumference (WC), fasting glucose, basal insulin, plasma lipids, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR), and 25(OH)D levels were measured. FINDRISC with WC cutoff points modified for Latin America was applied.

RESULTS

No difference in 25(OH)D levels between obese and nonobese subjects was found. When anthropometric, clinical, and biochemical variables according to the 25(OH)D status were compared, the only difference detected was higher LA-FINDRISC in the insufficient/low 25(OH)D group compared to normal 25(OH)D levels group (12.75±6.62; vs 10.15±5.21; p=0.031). LA-FINDRISC was negatively correlated with plasma 25(OH)D levels (r=-0.302; p=0.002) and positively correlated with the HOMA-IR index (r=0.637; p=0.0001).

CONCLUSIONS

The LA-FINDRISC significantly correlated with both 25(OH)D levels and insulin resistance markers in this group of patients.

A community-based primary prevention programme for type 2 diabetes mellitus integrating identification and lifestyle intervention for prevention: a cluster randomised controlled trial

Background

Prevention of type 2 diabetes mellitus (T2DM) is a global priority; however, there is a lack of evidence investigating how to effectively translate prevention research into a primary care setting.

Objectives

(1) To develop and validate a risk score to identify individuals at high risk of T2DM in the UK; and (2) to establish whether or not a structured education programme targeting lifestyle and behaviour change was clinically effective and cost-effective at preventing progression to T2DM in people with prediabetes mellitus (PDM), identified through a risk score screening programme in primary care.

Design

A targeted screening study followed by a cluster randomised controlled trial (RCT), with randomisation at practice level. Participants were followed up for 3 years.

Setting

A total of 44 general practices across Leicestershire, UK. The intervention took place in the community.

Participants

A total of 17,972 individuals from 44 practices identified through the risk score as being at high risk of T2DM were invited for screening; of these, 3449 (19.2%) individuals attended. All received an oral glucose tolerance test. PDM was detected in 880 (25.5%) of those screened. Those with PDM were included in the trial; of these, 36% were female, the average age was 64 years and 16% were from an ethnic minority group.

Intervention

Practices were randomised to receive either standard care or the intervention. The intervention consisted of a 6-hour group structured education programme, with an annual refresher and regular telephone contact.

Main outcome measures

The primary outcome was progression to T2DM. The main secondary outcomes were changes in glycated haemoglobin concentrations, blood glucose levels, cardiovascular risk, the presence of metabolic syndrome, step count and the cost-effectiveness of the intervention.

Results

A total of 22.6% of the intervention group did not attend the education and 29.1% attended all sessions. A total of 131 participants developed T2DM (standard care,n = 67; intervention,n = 64). There was a 26% reduced risk of T2DM in the intervention arm compared with standard care, but this did not reach statistical significance (hazard ratio 0.74, 95% confidence interval 0.48 to 1.14;p = 0.18). There were statistically significant improvements in glycated haemoglobin concentrations, low-density lipoprotein cholesterol levels, psychosocial well-being, sedentary time and step count in the intervention group. The intervention was found to result in a net gain of 0.046 quality-adjusted life-years over 3 years at a cost of £168 per patient, with an incremental cost-effectiveness ratio of £3643 and a probability of 0.86 of being cost-effective at a willingness-to-pay threshold of £20,000.

Conclusions

We developed and validated a risk score for detecting those at high risk of undiagnosed PDM/T2DM. We screened > 3400 people using a two-stage screening programme. The RCT showed that a relatively low-resource pragmatic programme may lead to a reduction in T2DM and improved biomedical and psychosocial outcomes, and is cost-effective.

Limitations

Only 19% of those invited to screening attended, which may limit generalisability. The variation in cluster size in the RCT may have limited the power of the study.

Future work

Future work should focus on increasing attendance to both screening and prevention programmes and offering the programme in different modalities, such as web-based modalities. A longer-term follow-up of the RCT participants would be valuable.

Finnish Diabetes Risk Score Is Associated with Impaired Insulin Secretion and Insulin Sensitivity, Drug-Treated Hypertension and Cardiovascular Disease: A Follow-Up Study of the METSIM Cohort

We investigated the association of the Finnish Diabetes Risk Score (FINDRISC) with insulin secretion, insulin sensitivity, and risk of type 2 diabetes, drug-treated hypertension, cardiovascular (CVD) events and total mortality in a follow-up study of the Metabolic Syndrome in Men (METSIM) cohort. The METSIM study includes 10,197 Finnish men, aged 45-73 years, and examined in 2005-2010. Of 8,749 non-diabetic participants of the METSIM study 693 developed incident type 2 diabetes, 225 started antihypertensive medication, 351 had a CVD event, and 392 died during a 8.2-year follow-up. The FINDRISC was significantly associated with decreases in insulin secretion and insulin sensitivity (P<0.0001), and with a 4.14-fold increased risk of incident type 2 diabetes, 2.43-fold increased risk of drug-treated hypertension, 1.61-fold increased risk of CVD, and 1.55-increased risk of total mortality (the FINDRISC ≥12 vs. < 12 points). In conclusion, the FINDRISC predicts impairment in insulin secretion and insulin sensitivity, the conversion to type 2 diabetes, drug-treated hypertension, CVD events and total mortality.

A Self-assessment Tool for Screening Young Adults at Risk of Type 2 Diabetes Using Strong Heart Family Study Data

PURPOSE

The purpose of this study is to characterize risk factors associated with type 2 diabetes in young adults aged 18 to 29 years to develop a noninvasive risk assessment tool for use with younger American populations.

METHODS

The self-assessment tool was developed with the Strong Heart Family Study data. A total of 590 young American Indian adults (242 men) who had normoglycemia and were not receiving diabetes treatment were included. Risk factors recommended by the American Diabetes Association were used to assess diabetes risk in these young adults. A logistic regression model was developed to calculate the predicted probability. The area under the receiver operating characteristic curve was used to evaluate the model.

RESULTS

The final model showed that parental history of diabetes, obesity level, alcohol consumption, and high fasting glucose, even within normal range, were significantly associated with onset of prediabetes/diabetes in 5 years. The area under the receiver operating characteristic curve value was 0.68 with original and validated data, indicating that the risk assessment tool had reasonably good discrimination ability.

CONCLUSIONS

This new noninvasive screening tool, based on data from American Indian young adults, has potential to screen young adults' early-onset diabetes risk. Future studies are warranted to test this risk assessment tool in other racial/ethnic young adults.

Cost-effectiveness of a risk-based secondary screening programme of type 2 diabetes

OBJECTIVE

The objective of this study was to develop a long-term economic model for type 2 diabetes to describe the entire spectrum of the disease over a wide range of healthcare programmes. The model evaluates a public health, risk-based screening programme in a country specific setting.

METHODS

The lifespan of persons and important phases of the disease and related interventions are recorded in a Markov model, which first simulates the effect of screening, then replicates important complications of diabetes, follows the progression of individuals through physiological variables and finally calculates outcomes in monetary and naturalistic units.

RESULTS

The introduction of the screening programme nearly doubled the proportion of diagnosed patients at the age of 50 and prolonged life expectancy. Three-yearly screening gained 0.0229 quality adjusted life years for an additional €83 per person compared with no screening and resulted an incremental cost-effectiveness ratio of €3630/quality adjusted life years.

CONCLUSION

From the economic perspective introduction of the 3-yearly screening programme is justifiable and it provides a good value for money. Copyright © 2016 John Wiley & Sons, Ltd.

Screening for type 2 diabetes mellitus in overweight and obese subjects made easy by the FINDRISC score

AIM

To evaluate the use of the FINDRISC score in an overweight and obese population to predict glucose status.

METHODS

In 651 overweight/obese subjects (M/F: 193/458, age 43±13 y, BMI 38.2±6.1kg/m(2)) glucose status was tested using OGTT and HbA1c. Furthermore, the FINDRISC questionnaire and CT visceral fat (VAT) and subcutaneous fat (SAT) were examined.

RESULTS

Exactly 50.4% were found to have prediabetes and 11.1% were newly diagnosed with type 2 diabetes (T2DM) (M/F=22.2/8.8%). Subjects without T2DM had a FINDRISC score of 11±3, those with pre-DM 13±4, and subjects with de novo T2DM 15±5. The aROC of the FINDRISC for detecting T2DM was 0.76 (95% CI 0.72-0.82), with 13 as cutoff point. The FINDRISC score correlated with VAT (r=0.34, p<0.001) and VAT/SAT ratio (r=0.39, p<0.001). The aROC of the FINDRISC to detect excess VAT was 0.79 (95%CI 0.72-0.84).

CONCLUSIONS

In a large group of overweight and obese subjects, 50.4% were found to have pre-DM and 11.1% were newly diagnosed with T2DM. The FINDRISC score increased with worsening of glucose tolerance status and proved to be an independent predictor of T2DM status, as did HOMA-B, HOMA-S and VAT. The FINDRISC can also function as a good tool to predict visceral obesity.

Analysis of the Japanese Diabetes Risk Score and fatty liver markers for incident diabetes in a Japanese cohort

AIMS

We examined the effectiveness of the Japanese Diabetes Risk Score (JPDRISC) and fatty liver markers for predicting incident diabetes.

METHODS

We created the JPDRISC. The study periods I and II were January 2007 to May 2009 and June 2009 to December 2011, respectively. A total of 2084 people (1389 men, 695 women; mean age: 46 years) were included. People with diabetes in the Period I and those with ethanol intake >140 g/week were excluded. A total of 1515 people were included. Fatty liver using ultrasonography scores (FLUS) were assigned.

RESULTS

The mean observation period was 26.3 months, and 24 people had developed diabetes between the Periods I and II. In logistic regression analysis, the JPDRISC (OR=1.197, 95% C.I.: 1.062-1.350, p=0.003) and FLUS (OR=2.591, 95% C.I.: 1.411-4.758, p=0.002) in the Period I were independent determinants of incident diabetes. In receiver operating characteristic analysis, sensitivity and specificity for incident diabetes were 0.885 and 0.536, respectively, in people with both FLUS≥1 and the total JPDRISC≥6 in the Period I. The sensitivity was better than the JPDRISC alone (sensitivity 0.696) and FLUS alone (sensitivity 0.750).

CONCLUSIONS

JPDRISC and FLUS were independently associated with incident diabetes and their combination is useful.

[Screening and prevention of diabetes]

A valid and efficient screening for individual diabetes risk is a highly welcomed tool in primary care and specialist medical practice. It is needed to detect early stages of diabetes risk and prediabetes and to start interventions that have the aim to prevent diabetes and also other chronic diseases from developing. The oral glucose tolerance test is the gold standard, but it is difficult to perform in an evidence-based manner in primary care. Furthermore, measuring fasting and 2-h postprandial glucose values detects only late stages of the pathophysiological development of type 2 diabetes. Interestingly, the 1-h glucose value is highly predictive of future diabetes risk, but is rarely used in primary care. Therefore, risk scores are commonly used to evaluate diabetes risk, but unfortunately, they generally do not mirror the relevance of increased risk due to the person's own lifestyle. Measuring waist circumference is another possibility, because the waist is directly associated with the amount of visceral fat, which again directly correlates with the pathophysiology of diabetes development. A further possibility is the EZSCAN™ technology. The EZSCAN™ is based on reverse iontophoresis, a new technology to detect very early forms of peripheral neuropathies, which are commonly associated with early diabetes risk stages. It is important to perform diabetes screening in a targeted manner, in both medical and paramedical environments, and it is mandatory to add targeted interventions, based on the screening evaluated diabetes risk.

Primary care screening for individuals with impaired glucose metabolism with focus on impaired glucose tolerance

AIM

To evaluate the utility of three short questions (the Skövde Form) combined with a random plasma glucose, and HbA1c as alternative tools for detection of individuals with impaired glucose metabolism (IGM), and particularly impaired glucose tolerance (IGT).

METHODS

Three questions concerning BMI ≥ 25 kg/m(2), heredity for type 2 diabetes, and known hypertension were asked in a random population of 573 individuals. All with two positive answers or one positive answer and a random plasma glucose > 7.2 mmol/l were invited for an oral glucose tolerance test and an HbA1c examination. FINDRISC was completed for comparison.

RESULTS

The positive predictive value (PPV) for IGM, using the Skövde Form, was 31% while sensitivity and specificity were 59% and 73%, respectively. Corresponding values for IGT were 11%, 50% and 69%. Using HbA1c ≥ 42 mmol/mol, the PPV for IGM was 64% while sensitivity and specificity were 28% and 97%, respectively. The corresponding values for IGT were 15%, 16% and 94%.

CONCLUSION

The Skövde Form combined with a random plasma glucose may be used as an alternative tool for detection of individuals with IGM and IGT in particular. HbA1c may be used to identify individuals with type 2 diabetes but fails to detect most individuals with prediabetes.

10-year risk estimation for type 2 diabetes mellitus and coronary heart disease in Kuwait: a cross-sectional population-based study

BACKGROUND

Type 2 diabetes mellitus (T2DM), coronary heart disease (CHD) and metabolic syndrome (MetS) are major healthcare problems in Kuwait. The present study was designed to determine the prevalence of MetS, and to estimate the 10-year risk for developing T2DM and CHD among the general population in Kuwait.

METHODS

A descriptive, cross-sectional survey was undertaken in 1800 individuals without diabetes or a history of cardiovascular disease (CVD). They were selected from six governorates using two stage convenience sampling. The questionnaire was developed using the Finnish Diabetes Risk Score (FINDRISK), Framingham Risk Score [FRS] and the 2009 Joint Statement criteria for diagnosis of MetS as a framework. Descriptive and multivariate logistic regression analyses were used.

RESULTS

The response rate was 89.4%. More than half (60.8%; 95% CI: 58.4-63.2) of responders were either overweight or obese. One hundred and ninety seven (12.2%) subjects had blood pressure (BP) ≥ 140/90 mm Hg. Almost three-in-ten (28.3%: 26.2-30.6) subjects had fasting plasma glucose (FPG) levels ≥ 5.6 mmol/l, of whom 86.0% and 14.0% had impaired fasting glucose (IFG) and screen detected T2DM, respectively. MetS was present in 512 (31.8%; 29.5-34.2) respondents. Just under one third (n = 481; 29.9%; 27.7-32.2) of participants were at moderate, high, or very high risk of developing T2DM, while 283 (17.6%: 15.8-19.6) were at moderate/high 10-year risk of developing CHD. Approximately one-in-ten (8.5%; 7.2-9.9) subjects were at moderate/high/very high 10-year risk of developing both T2DM/CHD. T2DM risk was higher for females compared to males (p < 0.001); however, the pattern was reversed in terms of the risk of developing CHD or T2DM/CHD. The risk of developing T2DM, CHD, or T2DM/CHD was greater among those aged ≥ 45 years, and those having MetS (p<0.001).

CONCLUSIONS

The current findings highlight the need for multifaceted interventions for prevention.

Metabolically healthy obesity from childhood to adulthood - Does weight status alone matter?

Up to 30% of obese people do not display the "typical" metabolic obesity-associated complications. For this group of patients, the term "metabolically healthy obese (MHO)" has been established during the past years and has been the focus of research activities. The development and severity of insulin resistance as well as (subclinical) inflammations seems to play a key role in distinguishing metabolically healthy from metabolically non-healthy individuals. However, an internationally consistent and accepted classification that might also include inflammatory markers as well as features of non-alcoholic fatty liver disease is missing to date, and available data - in terms of prevalence, definition and severity - are heterogeneous, both during childhood/adolescence and during adulthood. In addition, the impact of MHO on future morbidity and mortality compared to obese, metabolically non-healthy as well as normal weight, metabolically healthy individuals is absolutely not clear to date and even conflicting. This review summarizes salient literature related to that topic and provides insight into our current understanding of MHO, covering all age spans from childhood to adulthood.

Evaluation of Finnish Diabetes Risk Score in screening undiagnosed diabetes and prediabetes among U.S. adults by gender and race: NHANES 1999-2010

Objective

To evaluate the performance of Finnish Diabetes Risk Score (FINDRISC) in detecting undiagnosed diabetes and prediabetes among U.S. adults by gender and race.

Methods

This cross-sectional analysis included participants (aged ≥20 years) from the National Health and Nutrition Examination Survey (NHANES) 1999–2010. Sensitivity, specificity, area under the receiver operating characteristic (ROC) curve and the optimal cutoff points for identifying undiagnosed diabetes and prediabetes were calculated for FINDRISC by gender and race/ethnicity.

Results

Among the 20,633 adults (≥20 years), 49.8% were women and 53.0% were non-Hispanic White. The prevalence of undiagnosed diabetes and prediabetes was 4.1% and 35.6%, respectively. FINDRISC was positively associated with the prevalence of diabetes (OR = 1.48 for 1 unit increase, p<0.001) and prediabetes (OR = 1.15 for 1 unit increase, p<0.001). The area under ROC for detecting undiagnosed diabetes was 0.75 for total population, 0.74 for men and 0.78 for women (p = 0.04); 0.76 for White, 0.76 for Black and 0.72 for Hispanics (p = 0.03 for White vs. Hispanics). The area under ROC for detecting prediabetes was 0.67 for total population, 0.66 for men and 0.70 for women (p<0.001); 0.68 for White, 0.67 for Black and 0.65 for Hispanics (p<0.001 for White vs. Hispanics). The optimal cutoff point was 10 (sensitivity = 0.75) for men and 12 (sensitivity = 0.72) for women for detecting undiagnosed diabetes; 9 (sensitivity = 0.61) for men and 10 (sensitivity = 0.69) for women for detecting prediabetes.

Conclusions

FINDRISC is a simple and non-invasive screening tool to identify individuals at high risk for diabetes in the U.S. adults.

Combination of diabetes risk factors and hepatic steatosis in Chinese: the Cardiometabolic Risk in Chinese (CRC) Study

Aims

Hepatic steatosis has been related to insulin resistance and increased diabetes risk. We assessed whether combination of diabetes risk factors, evaluated by the Finnish Diabetes Risk Score, was associated with risk of hepatic steatosis in an apparently healthy Chinese population.

Research Design and Methods

The study samples were from a community-based health examination survey in central China. In total 1,780 men and women (18–64 y) were included in the final analyses. Hepatic steatosis was diagnosed by ultrasonography. We created combination of diabetes risk factors score on basis of age, Body Mass Index, waist circumference, physical activity at least 4 h a week, daily consumption of fruits, berries or vegetables, history of antihypertensive drug treatment, history of high blood glucose. The total risk score is a simple sum of the individual weights, and values range from 0 to 20.

Results

Hepatic steatosis was present 18% in the total population. In multivariate models, the odds ratios of hepatic steatosis were 1.20 (95%CI 1.15–1.25) in men and 1.25 (95%CI 1.14–1.37) in women by each unit increase in the combination of diabetes risk factors score, after adjustment for blood pressure, liver enzymes, plasma lipids, and fasting glucose. The area under the receiver operating characteristic curve for hepatic steatosis was 0.78 (95%CI 0.76–0.80), 0.76 in men (95%CI 0.74–0.78) and 0.83 (95%CI 0.79–0.87) in women.

Conclusions

Our data suggest that combination of major diabetes risk factors was significantly related to risk of hepatic steatosis in Chinese adults.

Evaluation of the Finnish Diabetes Risk Score (FINDRISC) as a screening tool for the metabolic syndrome

OBJECTIVES

Traditionally, the Finnish Diabetes Risk Score (FINDRISC) questionnaire is a screening tool to estimate risk of type 2 diabetes. In this study, we evaluated the ability of FINDRISC to predict the development of the metabolic syndrome (MetS) in an Iranian population without diabetes and MetS.

METHODS

A total of 1,010 first-degree relatives of consecutive patients with type 2 diabetes, 30-70 years old (274 men and 736 women), without diabetes and MetS, were examined and followed up over 8.0 ± 1.6 years (mean ± SD) for MetS incidence. The incidence of MetS was examined across quartiles of FINDRISC, and a receiver operating characteristic (ROC) curve was plotted to assess the discrimination. At baseline and through follow-ups, participants underwent a standard 75 g 2-hour oral glucose tolerance test (OGTT). Data for determining FINDRISC were available from each participant.

RESULTS

During 8,089 person-years of follow-up, 69 men and 209 women without MetS and diabetes at baseline subsequently developed MetS. The incidence of MetS was 31.4 per 1000 person-years in men and 35.5 in women. The FINDRSC at baseline was significantly associated with MetS evolution. Participants in the top quartile of FINDRISC were 4.4 times more likely to develop MetS than those in the bottom quartile (rate ratio 4.4; 95% CI 2.7-7.0). The area under the ROC curve was 65.0% (95% CI 61.3-68.7).

CONCLUSION

The results of this study suggest that FINDRISC can be applied to detect MetS in a high-risk population.

A comparison of three different diabetes screening methods among dental patients in Turkey

OBJECTIVE

This study was conducted to describe the frequency of diabetes in dental patients, and to compare three different screening methods: the random finger plasma glucose (RFPG) test, the Finnish diabetes risk score (FINDRISC) survey and a special clinical guideline developed for dental patients.

METHODS

The study design was cross-sectional, descriptive and comparative. The data were collected between August 2011 and February 2012. A total of 702 dental patients participated in this study. The screening tools were RFPG, FINDRISC and a clinical guideline. Data were analyzed using the Chi-squared test, the t test, analysis of variance, and the Pearson correlation test.

RESULTS

The frequency of diabetes was 8.3% for the participants. The prevalence of participants at risk for undiagnosed diabetes was 20.1% according to the RFPG test, 29.9% according to the FINDRISC, and 29.8% according to the clinical guideline. Correlation analysis showed a significant positive correlation between the screening methods (p<0.001 for each).

CONCLUSION

The overall frequency of diabetes was 8.3%. It was found that the three screening methods used in this study were statistically similar. However, FINDRISC and clinical guideline as the questionnaire screening tools indicated a little larger group than RFPG with respect to diabetes risk.

Finnish Diabetes Risk Score to predict type 2 diabetes in the Isfahan diabetes prevention study

AIM

The strong association between the Finnish Diabetes Risk Score (FINDRISC) and risk of diabetes reported in European populations cannot necessarily be generalized to other populations. The aim of this study was to evaluate the ability of FINDRISC to predict progression to diabetes in an Iranian population without diabetes.

METHODS

A total of 1537 first-degree relatives (FDR) without diabetes of consecutive people with type 2 diabetes 30-70 years old (376 men and 1161 women) were examined and followed for a mean (SD) of 7.8 (1.7) years for diabetes incidence. We examined the incidence of diabetes across quartiles of FINDRISC and plotted a receiver operating characteristic (ROC) curve to assess discrimination. At baseline and through follow-up, participants underwent a standard 75-g 2-h oral glucose tolerance test. Data for the FINDRISC were available from each participant.

RESULTS

During 12,046 person-years of follow-up, 41 men and 154 women developed diabetes. The incidence of type 2 diabetes was 14.0 per 1000 person-years in men and 16.9 in women. Those in the top quartile of FINDRISC were 21.7 times more likely to develop diabetes than those in the bottom quartile (relative risk 21.7; 95% CI 9.90, 47.39). The area under the ROC was 75.1% (95% CI 71.3, 78.8).

CONCLUSIONS

The results of this study show that FINDRISC is a robust predictor of type 2 diabetes in high-risk individuals in Iran.

Assessment of small fiber neuropathy to predict future risk of type 2 diabetes

OBJECTIVE

Sudomotor dysfunction due to small fiber neuropathy can be observed very early in pre-diabetes. The aim of this study was to assess the predictive power of EZSCAN, a non invasive, quick and simple measurement of sudomotor function to identify glucose impairment.

RESEARCH DESIGN AND METHODS

The study was performed in 76 German subjects at risk of diabetes. Glucose metabolism was assessed by using, oral glucose tolerance test (OGTT) at baseline and after 2 year follow-up. Sudomotor function was evaluated by measuring hand and foot electrochemical sweat conductances to calculate a risk score.

RESULTS

At baseline, 38 patients had normal glucose tolerance (NGT), 34 had pre-diabetes (impaired fasting glucose, IFG and/or impaired glucose tolerance, IGT) and 4 had newly diagnosed type 2 diabetes. The AUC values for FPG, 2h-OGTT glucose, 1h-OGTT glucose, HbA1C and EZSCAN score to predict pre-diabetes were 0.50, 0.65, 0.64, 0.72 and 0.76, respectively. Subjects having a moderate or high EZSCAN score (>50) at baseline had a substantially increased risk for having IFG and/or IGT at follow-up visit presented by an odds ratio of 12.0 [1.4-100.5], the OR for having 1h-OGTT ≥ 8.6mmol/L at follow-up was 9.8 [1.0-92.8] and for having HbA1C ≥ 5.7% was 15.7 [1.9-131.5] compared to subjects with low EZSCAN risk.

CONCLUSIONS

This preliminary study, which must be confirmed in a larger population, shows that EZSCAN risk score is associated with diabetes progression which have implications for prevention and disease management.

Risk-assessment score for screening diabetes mellitus among Omani adults

PURPOSE

The purpose of this study was to evaluate a self-administered risk-assessment scoring system for identifying Omani adults with type 2 diabetes mellitus (T2DM).

METHODS

An exploratory cross-sectional design was used. Simple random sampling was used to select 93 adults in Muscat. Ethical approval was obtained from the College of Nursing Research and Ethics Committee. The Finnish Diabetes Risk Score (FINDRISC) was used to collect the data in 2009. Informed consent was obtained from the participants. Data were analysed with the Pearson chi-square test.

RESULTS

A total of 9.7% of the adults had very high FINDRISC and 17.2% had slightly elevated risk of developing T2DM within 10 years. The risk assessment (family history, waist circumference, body mass index, physical activity, dietary intake, hypertension and high blood glucose) of T2DM was significant and positively related to the prediction of T2DM among Omani adults.

Characteristics of American young adults with increased risk for type 2 diabetes: a pilot study

PURPOSE

The purpose of the study was to examine the characteristics of American young adults with increased risk for type 2 diabetes (T2D).

METHODS

Participants ages 18 to 29, overweight/obese, and sedentary were recruited from the metro Atlanta area in the United States. Variables included demographics, anthropometric and clinical variables, and physical activity. Of 107 participants, 3 participants had undiagnosed diabetes and 1 participant did not complete the modifiable activity questionnaire. Thus, 103 young adults remained for the final data analysis.

RESULTS

Most participants were females and African Americans. About 30% of participants had prediabetes, either impaired fasting glucose, an A1C of 5.7% to 6.4%, or both. Overall, prediabetes young adults were heavier and did less physical activity than Diabetes Prevention Program (DPP) trial participants. In addition, these young adults had a higher prevalence of parental T2D history and lower level of physical activity compared to young adults with normoglycemia.

CONCLUSIONS

Physical activity and parent T2D history are key risk factors for identifying young adults with prediabetes. Multilevel strategies are necessary to raise awareness of diabetes risk and to prevent T2D in young adults.

The European perspective of diabetes prevention: the need for individualization of diabetes prevention

Over the last decade the situation for people with diabetes mellitus in Europe has changed significantly. The number of patients increases continuously, the age of diagnosis decreases and effective management grows to become a burden for European healthcare systems. In this situation numerous stakeholders try to develop concepts for innovative chronic care management as well as individualized and personalized diabetes management. A major focus is set to activities for early screening and prevention of the diabetes and associated diseases. The present article will give an overview about current achievements in European projects addressing the unmet needs in diabetes management and also to introduce undergoing projects in the field of diabetes prevention and care. Furthermore, the SweetSmart concept will be presented, which is the initiation of a strategy to individualize interventions for the prevention of diabetes and care management. In the current discussion about the management of health care resources it is important to have a strategic vision about a realistic future of innovative chronic care management.

The association between body mass index and health-related quality of life: influence of ethnicity on this relationship

AIMS

The association between obesity and a poorer health-related quality of life (HRQL) has previously been explored. The influence of ethnicity on this relationship has less frequently been considered. We aimed to explore the relationship between body mass index (BMI) and HRQL in a mixed population of White European (WE) and South Asian (SA) ethnicity.

METHODS

Cross-sectional data were analysed (n = 4989, 16% SA) from a population-based diabetes screening study. BMI categories were based on ethnic-specific cut-points. HRQL was categorized low (<0.848) or high (≥0.848) according to the median EQ5D score. Logistic regression was used to examine the relationship between BMI and HRQL. Interaction analysis was conducted to determine the effect of ethnicity.

RESULTS

Overweight (OR = 1.22, 95% CI: 1.10-1.41, p < 0.001) and obese people (OR = 1.81, 95% CI: 1.56-2.10, p < 0.001) had increased odds of having a low HRQL compared to normal weight people. After adjusting for potential confounders, age, gender, ethnicity, deprivation score, fruit and vegetable intake, physical activity, cardiovascular disease, chronic kidney disease and smoking, this association was strengthened further. However, for obese people, SA ethnicity significantly reduced the risk of having a low HRQL when compared to WEs (adjusted OR = 0.58, 95% CI: 0.34-0.97).

CONCLUSIONS

Our findings provide further evidence of an association between increasing BMI and low HRQL but suggest that SA ethnicity modifies this relationship. These results could have important health implications and are a basis for further research.

Prevalence of undiagnosed abnormal glucose tolerance in adult patients cared for by general practitioners in Hungary. Results of a risk-stratified screening based on FINDRISC questionnaire

BACKGROUND

The prevalence of type 2 diabetes mellitus is rapidly increasing, worldwide and also in Hungary. Timely diagnosis and early treatment could be aided by targeted screening. Recognizing this, the Hungarian Diabetes Association initiated a risk-stratified screening with the involvement of primary care physicians.

MATERIAL/METHODS

In the first phase of screening, the FINDRISC questionnaire was completed, followed by an oral glucose tolerance test (OGTT) for those with a score of ≥12. Between September 1, 2010 and March 31, 2011, 70,432 non-diabetic adults, who visited their general practitioners for any reason, were involved in the screening. Of these, 68,476 questionnaires proved to be suitable for processing.

RESULTS

From the questionnaires, 28,077 (41.0%) had a score of ≥12. A valid OGTT was performed in 22,846 cases; of this group 3,217 subjects (14.1%) had elevated fasting glucose levels, 5,663 (24.8%) had impaired glucose tolerance, and 1,750 (7.6%) had manifest, previously undiagnosed, diabetes mellitus. Overall, from the valid OGTT group, 46.5% subjects had some degree of glucose intolerance.

CONCLUSIONS

Based on the FINDRISC questionnaire, the risk-stratified screening for diabetes mellitus proved to be simple and cost-effective method for the early detection of carbohydrate metabolism disorders. Using this method, the prevalence rate of previously undiagnosed abnormal glucose tolerance was high in adult patients cared for by general practitioners in Hungary.

Development and evaluation of a Web-based tool to estimate type 2 diabetes risk: Diab_Alert

OBJECTIVE

Diabetes and its complications are major causes of morbidity and mortality around the world. This article presents a new multilingual, mobile-compatible Web-based tool to estimate the risk of suffering from type 2 diabetes (Diab_Alert) after the individual answers a brief questionnaire. The rationale for building the tool is to raise the public awareness of diabetes and its consequences. People should be concerned about the fact that this disease can be prevented even in cases of prediabetes, when medication is crucial to avoid the emergence of diabetes. The application shows a message with the global risk for each user and encloses with it a graph that shows the probability of suffering from diabetes in the next 10 years, which other tools do not illustrate. This way, people at high risk can ask for advice from their physician and get basal glucose tests done more often.

SUBJECTS AND METHODS

The questions are based on research performed by experts, mainly the Diabetes Population Risk Tool and the Finnish Diabetes Risk Score.

RESULTS

Up to April 26, 2012, 141 users have completed this test. Of this group, 125 have used the Spanish language version, and of the other participants, 7 used English, 7 used Portuguese, and 2 used French. The number of individuals who have completed the questionnaire is too small to draw conclusions, although results are not as advanced as expected. Most of them are young and hence are at low risk, but those over 45 years of age are at a higher risk, especially men.

CONCLUSIONS

This tool can help users become more aware of their risk of diabetes and initiate lifestyle changes, such as improved nutrition or increased physical activity, which may reduce their risk of developing the disease. The tool has been designed to be easily translated into multiple languages and to work on multiple platforms, with a standard version for computers and a simpler version for mobile devices.

Improving prediction algorithms for cardiometabolic risk in children and adolescents

Clustering of abnormal metabolic traits, the Metabolic Syndrome (MetS), has been associated with an increased cardiovascular disease (CVD) risk. Several algorithms including the MetS and other risk factors exist for adults to predict the risk of CVD. We discuss the use of MetS scores and algorithms in an attempt to predict later cardiometabolic risk in children and adolescents and offer suggestions for developing clinically useful algorithms in this population. There is little consensus in how to define the MetS or to predict future CVD risk using the MetS and other risk factors in children and adolescents. The MetS scores and prediction algorithms we identified had usually not been tested against a clinical outcome, such as CVD, and they had not been validated in other populations. This makes comparisons of algorithms impossible. We suggest a simple two-step approach for predicting the risk of adult cardiometabolic disease in overweight children. It may have advantages in terms of cost-effectiveness since it uses simple measurements in the first step and more complex, costly measurements in the second step. It also takes advantage of the continuous distributions of the metabolic features. We suggest piloting and validating any new algorithms.

Feasibility of the FINDRISC questionnaire to identify individuals with impaired glucose tolerance in Swedish primary care. A cross-sectional population-based study

AIM

To evaluate the performance of the FINDRISC questionnaire as a tool to recruit individuals with impaired glucose tolerance for lifestyle intervention programmes.

METHODS

A cross-sectional population-based study in primary Health Care Centres in a middle-sized Swedish town. All 9734 individuals, aged 35-75 years, living within a defined area, were invited by mail to fill in and return the FINDRISC questionnaire. Participants with a risk score ≥ 15 (n = 525) were invited to perform an oral glucose tolerance test while those with known diabetes were excluded.

RESULTS

In total, 5452 questionnaires (58%) were returned and revealed a mean risk-score of 8.5 ± 4.5 (mean ± SD). We found that 525 participants had a risk-score ≥ 15 and 302 (58%) were further examined with an oral glucose tolerance testing (OGTT). Among them we detected 11% with previously undiagnosed Type 2 diabetes, 16% with impaired glucose tolerance and 29% with impaired fasting glucose. A FINDRISC score ≥ 15 was associated with a positive predictive value of 55% for impaired glucose metabolism (impaired fasting glucose + impaired glucose tolerance + Type 2 diabetes) and of 16% for impaired glucose tolerance, respectively. The positive predictive value for impaired glucose tolerance did not increase to more than 17% when choosing the cut-point 17, while there was a significant increase in the positive predictive value for impaired glucose metabolism (70%).

CONCLUSIONS

The FINDRISC questionnaire is a useful instrument for identification of individuals with impaired glucose metabolism but seems less effective for detection of individuals with impaired glucose tolerance. Strategies to find individuals with impaired glucose tolerance for implementation of lifestyle changes in primary care should therefore be developed further.

Hyperuricemia in young adults and risk of insulin resistance, prediabetes, and diabetes: a 15-year follow-up study

The objective of this study was to assess the utility of hyperuricemia as a marker for diabetes and prediabetes (impaired fasting glucose) and insulin resistance in young adults. Using Cox proportional hazards regression models, the authors analyzed 15-year follow-up data on 5,012 persons in 4 US cities who were aged 18-30 years and diabetes-free at the time of enrollment. At baseline (1986), 88% of participants had a body mass index (weight (kg)/height (m)(2)) less than 30. During the follow-up period (through 2001), the incidence rates of diabetes and prediabetes (insulin resistance and impaired fasting glucose) were higher among persons with greater serum urate concentrations. In multivariable Cox regression analyses that adjusted for age, gender, race, body mass index, family history of diabetes, diastolic blood pressure, total cholesterol, smoking, and alcohol use, the hazard ratios for diabetes, insulin resistance, and prediabetes among persons with hyperuricemia (serum urate level >7 mg/dL vs. ≤7.0 mg/dL) were 1.87 (95% confidence interval (CI): 1.33, 2.62), 1.36 (95% CI: 1.23, 1.51), and 1.25 (95% CI: 1.04, 1.52), respectively. This observation was generally consistent across subgroups. The authors conclude that hyperuricemia in the midtwenties is an independent marker for predicting diabetes and prediabetes among young adults in the subsequent 15 years.
