Global status of diabetes prevention and prospects for action: A consensus statement.

Primary prevention of type 2 diabetes (T2D) should be achievable through the implementation of early and sustainable measures. Several randomized control studies that found success in preventing the progression to T2D in high-risk populations have identified early and intensive intervention based on an individualized prevention model as the key factor for participant benefit. The global prevalence of both overweight and obesity has now been widely recognized as the major epidemic of the 21st century. Obesity is a major risk factor for the progression from normal glucose tolerance to prediabetes and then to T2D. However, not all obese individuals will develop prediabetes or progress to diabetes. Intensive, multicomponent behavioural interventions for overweight and obese adults can lead to weight loss. Diabetes medications, including metformin, GLP-1 agonists, glitazones, and acarbose, can be considered for selected high-risk patients with prediabetes when lifestyle-based programmes are proven unsuccessful. Nutrition education is the cornerstone of a healthy lifestyle. Also, physical activity is an integral part of the prediabetes management plan and one of the main pillars in the prevention of diabetes. Mobile phones, used extensively worldwide, can facilitate communication between health professionals and the general population, and have been shown to be helpful in the prevention of T2D. Universal screening is needed. Noninvasive risk scores should be used in all countries, but they should be locally validated in all ethnic populations focusing on cultural differences around the world. Lifestyle interventions reduce the progression to prediabetes and diabetes. Nevertheless, many questions still need to be answered.

Managing dysfunctional central venous access devices: a practical approach to urokinase thrombolysis.

Tunnelled central venous access devices (CVADs) are defined as any intravenous multipurpose catheters placed within the central veins for use in haemodialysis and administration of blood products or chemotherapy in oncology and haematological conditions. Frequent complications include thrombosis and catheter-related infection, which may lead to significant adverse patient outcomes. Once thrombosis is suspected correction should be attempted empirically with thrombolytic agents. Commonly available thrombolytic agents in the UK include urokinase (Syner-Kinase) and alteplase (Cathflo). It is well recognised that urokinase usage differs widely and concerns were raised by clinicians about the variation of dose regimens nationally. The objective of the CVAD Focus Group was to address this issue and offer guidance in the management of suspected thrombosis of CVAD with urokinase using two algorithms for renal and non-renal dysfunctional CVAD and to audit prospectively the outcomes of intervention.

Risk and incidence of cognitive impairment in patients with chronic kidney disease and diabetes: the results from a longitudinal study in a community cohort of patients and an age and gender-matched control cohort in North Wales, UK.

OBJECTIVES: The aim of the current investigation is to estimate the incidence and risk for neurocognitive disorders (NCD) in a chronic kidney disease (CKD) cohort with diabetes, compared with an age and sex-matched control cohort. DESIGN: Longitudinal follow-up. SETTING: District general hospital North Wales, UK. PARTICIPANTS: Ninety-two patients with CKD and an age and gender-matched sample of 143 controls at baseline and at approximately 36 months. INTERVENTIONS: Cognitive function was assessed in the patients with CKD (mean age 75.8±9.1; 49 men: 43 women) and the control cohort (mean age 74.4±6.2; 71 men: 72) at baseline and at approximately 36 months. An NCD diagnosis was based on patient, informant, case note review, neuropsychological assessment and application of Diagnostic and Statistical Manual of Mental disorders V.5 (DSM-5) for an NCD and Petersen's criteria for mild cognitive impairment. RESULTS: Follow-up neuropsychological assessment and application of DSM-5 criteria of the cognitively normal patients and controls revealed, 25/92 (27%) of the CDK and 20/143 (13.9%) in the control cohort developed an NCD. The CKD cohort had a twofold increased risk for the development of an NCD compared with the controls, adjusted for age and sex. The incidence rate for an NCD in the CKD cohort was 10.5 and 5.1 in the controls, respectively. No association was observed with the stage of CKD and cognitive function. CONCLUSIONS: This longitudinal investigation found that patients with CKD have a twofold increased risk for the development of an NCD. The current investigation highlighted the need to recognise that NCD in patients with CKD is a common comorbidity and that they are at a much higher risk for the development of a significant neurodegenerative disorders. In view of these risks, neuropsychological screening and assessment should be incorporated into normal CKD clinical practice and management.

Are We Following iRefer Guidelines From the Royal College of Radiology When Requesting Abdominal X-rays?

Background Abdominal radiography is one of the most routinely performed radiological investigations in hospitals. It is one of the initial investigations done in hospitals. Numerous studies have shown that abdominal X-rays have low sensitivity in several conditions such as acute abdominal pain. Methodology This study aims to first identify whether the Royal College of Radiology guidelines are being adhered to while requesting abdominal X-rays and, second, to identify the number of unnecessary requests made in the Betsi Cadwaladr health board. This is a retrospective audit of abdominal X-ray request data collected between the 1st and 23rd of August 2022. Data were collected from the electronic radiology record system. iRefer guidelines by the Royal College of Radiology were used as a reference to compare the requests made, and data were then analysed accordingly. Data are reported descriptively using percentages. Data analysis was done using SPSS version 20 (IBM Corp., Armonk, NY, USA). Results Of the total 242 abdominal X-rays noted, 89.67% of requests were according to the iRefer guidelines while 10.33% of requests were not. A total of 73.14% of cases were suspected to have an intestinal obstruction, and the positivity rate for the same was only 12.39%. Conclusions The majority of the requests followed the guidelines. However, there is an urgent need to develop local guidelines to reduce needless abdominal X-rays.

Prospective Audit to Study urokinaSe use to restore Patency in Occluded centRal venous caTheters in haematology and oncology patients (PASSPORT 2).

BACKGROUND: Central venous catheter dysfunction may be associated with intraluminal clots, drug precipitates and lipid residues or extra luminal causes such as fibroblastic sleeve, tip malposition, pinch-off syndrome and venous thrombosis at the tip of central venous catheter. Failure to restore patency after addressing these causes, empirical treatment with thrombolytic agents should be considered. Urokinase is used widely as a thrombolytic agent but very few outcome studies have been published. METHODS: A multicentre group conducted a prospective audit of management of central venous catheter dysfunction after exclusion of common causes using in centre standardised doses of urokinase from September 2017 to February 2018 in haematology and oncology units. Data of catheter blood flow were collected anonymously following administration of 5000- to 25,000-IU urokinase in dysfunctional central venous catheter. RESULTS: A total of 117 patients were recruited from eight centres, 54 females and 63 males, median age was 60 (46-68). In total, 53% presented as partial withdrawal occlusion and 47% total occlusion. In partial withdrawal occlusion, patency was restored in 80% of interventions, in 82% of interventions using push lock and in 76% using dwell lock. In total occlusion, patency was restored in 88% of the interventions. The central venous catheter clearance rate was dose dependent; patency was restored in 83% of central venous catheter with 5000 IU, 89% with 10,000 IU and 92% with high dose of 25,000 IU. No adverse events were recorded. CONCLUSION: In this study, treatment of dysfunctional central venous catheter using standardised urokinase doses was safe and effective in restoring patency when no other mechanical causes could account for central venous catheter dysfunction.

Structured hypertension education program for people with type 2 diabetes, the SHED study.

OBJECTIVES: There is enough evidence that patient education and lifestyle modification has shown benefits in diabetes care, however the evidence is less for improving care of hypertension. Our study is the first in the UK to assess the impact of a structured hypertension education program in subjects with type 2 diabetes. DESIGN: Prospective randomised controlled study. SETTING AND INTERVENTION: From a diabetes clinic in a district and general hospital in UK 132 participants were equally randomised into intervention group and control group. Intervention included a once weekly education session for 4 weeks together with home blood pressure monitoring and dose changes in antihypertensives. Base line data was recorded with follow up after 3 and 6 months. RESULTS: More participants achieved target BP in the intervention group versus control. This difference appeared early at the 3rd months (48.8% versus 20.4% respectively, p = 0.007) and remained at the 6th month (58.1% versus 20.4% respectively, p < 0.001). The change in number of pills was significantly lower in the intervention group. The mean increase in antihypertensive pills was 0.22 ± 0.48 (13 ± 30% increase) in the intervention group versus 0.62 ± 0.68 (41 ± 60% increase) in the routine group (p = 0.014), denoting less need to escalate treatment. CONCLUSION: We demonstrated that our structured education program has led to a significantly higher percentage of participants achieving the BP target, early after intervention, together with a significant reduction in the number of antihypertensive pills.

Managing Access by Generating Improvements in Cannulation: A national quality improvement project.

Cannulation is essential for haemodialysis with arteriovenous access, but also damages the arteriovenous access making it prone to failure, is associated with complications and affects patients' experiences of haemodialysis. Managing Access by Generating Improvements in Cannulation is a national UK quality improvement project, designed to improve cannulation practice in the United Kingdom, ensuring it reflects current needling recommendations. It uses a simple quality improvement method, the Model for Improvement, to structure improvement to cannulation practice. It assists units in the practical implementation of the British Renal Society and Vascular Access Society of Britain and Ireland needling recommendations, ensuring actual cannulation practice reflects what is defined as best practice in cannulation. An eLearning package and awareness materials have been developed, to assist units in changing their cannulation practice. The Kidney Quality Improvement Partnership provides a structure for Managing Access by Generating Improvements in Cannulation that promotes development and dissemination. It is hoped that Managing Access by Generating Improvements in Cannulation will raise an understanding about the cannulation of arteriovenous access and change behaviours and beliefs around correct cannulation practice, to ensure longevity of this lifeline.

The PrEscription of intraDialytic exercise to improve quAlity of Life in patients with chronic kidney disease trial: study design and baseline data for a multicentre randomized controlled trial.

BACKGROUND: Exercise interventions designed to improve physical function and reduce sedentary behaviour in haemodialysis (HD) patients might improve exercise capacity, reduce fatigue and lead to improved quality of life (QOL). The PrEscription of intraDialytic exercise to improve quAlity of Life study aimed to evaluate the effectiveness of a 6-month intradialytic exercise programme on QOL and physical function, compared with usual care for patients on HD in the UK. METHODS: We conducted a prospective, pragmatic multicentre randomized controlled trial in 335 HD patients and randomly (1:1) assigned them to either (i) intradialytic exercise training plus usual care maintenance HD or (ii) usual care maintenance HD. The primary outcome of the study was the change in Kidney Disease Quality of Life Short Form (KDQOL-SF 1.3) Physical Component Score between baseline and 6 months. Additional secondary outcomes included changes in peak aerobic capacity, physical fitness, habitual physical activity levels and falls (International Physical Activity Questionnaire, Duke's Activity Status Index and Tinetti Falls Efficacy Scale), QOL and symptom burden assessments (EQ5D), arterial stiffness (pulse wave velocity), anthropometric measures, resting blood pressure, clinical chemistry, safety and harms associated with the intervention, hospitalizations and cost-effectiveness. A nested qualitative study investigated the experience and acceptability of the intervention for both participants and members of the renal health care team. RESULTS: At baseline assessment, 62.4% of the randomized cohort were male, the median age was 59.3 years and 50.4% were white. Prior cerebrovascular events and myocardial infarction were present in 8 and 12% of the cohort, respectively, 77.9% of patients had hypertension and 39.4% had diabetes. Baseline clinical characteristics and laboratory data for the randomized cohort were generally concordant with data from the UK Renal Registry. CONCLUSION: The results from this study will address a significant knowledge gap in the prescription of exercise interventions for patients receiving maintenance HD therapy and inform the development of intradialytic exercise programmes both nationally and internationally.

Randomized Trial-PrEscription of intraDialytic exercise to improve quAlity of Life in Patients Receiving Hemodialysis.

INTRODUCTION: Whether clinically implementable exercise interventions in people receiving hemodialysis (HD) therapy improve health-related quality of life (HRQoL) remains unknown. The PrEscription of intraDialytic exercise to improve quAlity of Life (PEDAL) study evaluated the clinical benefit and cost-effectiveness of a 6-month intradialytic exercise program. METHODS: In a multicenter, single-blinded, randomized, controlled trial, people receiving HD were randomly assigned to (i) intradialytic exercise training (exercise intervention group [EX]) and (ii) usual care (control group [CON]). Primary outcome was change in Kidney Disease Quality of Life Short-Form Physical Component Summary (KDQOL-SF 1.3 PCS) from baseline to 6 months. Cost-effectiveness was determined using health economic analysis; physiological impairment was evaluated by peak oxygen uptake; and harms were recorded. RESULTS: We randomized 379 participants; 335 and 243 patients (EX n = 127; CON n = 116) completed baseline and 6-month assessments, respectively. Mean difference in change PCS from baseline to 6 months between EX and CON was 2.4 (95% confidence interval [CI]: -0.1 to 4.8) arbitrary units (P = 0.055); no improvements were observed in peak oxygen uptake or secondary outcome measures. Participants in the intervention group had poor compliance (47%) and poor adherence (18%) to the exercise prescription. Cost of delivering intervention ranged from US$598 to US$1092 per participant per year. The number of participants with harms was similar between EX (n = 69) and CON (n = 56). A primary limitation was the lack of an attention CON. Many patients also withdrew from the study or were too unwell to complete all physiological outcome assessments. CONCLUSIONS: A 6-month intradialytic aerobic exercise program was not clinically beneficial in improving HRQoL as delivered to this cohort of deconditioned patients on HD.

Exercise programme to improve quality of life for patients with end-stage kidney disease receiving haemodialysis: the PEDAL RCT.

BACKGROUND: Whether or not clinically implementable exercise interventions in haemodialysis patients improve quality of life remains unknown. OBJECTIVES: The PEDAL (PrEscription of intraDialytic exercise to improve quAlity of Life in patients with chronic kidney disease) trial evaluated the clinical effectiveness and cost-effectiveness of a 6-month intradialytic exercise programme on quality of life compared with usual care for haemodialysis patients. DESIGN: We conducted a prospective, multicentre randomised controlled trial of haemodialysis patients from five haemodialysis centres in the UK and randomly assigned them (1 : 1) using a web-based system to (1) intradialytic exercise training plus usual-care maintenance haemodialysis or (2) usual-care maintenance haemodialysis. SETTING: The setting was five dialysis units across the UK from 2015 to 2019. PARTICIPANTS: The participants were adult patients with end-stage kidney disease who had been receiving haemodialysis therapy for > 1 year. INTERVENTIONS: Participants were randomised to receive usual-care maintenance haemodialysis or usual-care maintenance haemodialysis plus intradialytic exercise training. MAIN OUTCOME MEASURES: The primary outcome of the study was change in Kidney Disease Quality of Life Short Form, version 1.3, physical component summary score (from baseline to 6 months). Cost-effectiveness was determined using health economic analysis and the EuroQol-5 Dimensions, five-level version. Additional secondary outcomes included quality of life (Kidney Disease Quality of Life Short Form, version 1.3, generic multi-item and burden of kidney disease scales), functional capacity (sit-to-stand 60 and 10-metre Timed Up and Go tests), physiological measures (peak oxygen uptake and arterial stiffness), habitual physical activity levels (measured by the International Physical Activity Questionnaire and Duke Activity Status Index), fear of falling (measured by the Tinetti Falls Efficacy Scale), anthropometric measures (body mass index and waist circumference), clinical measures (including medication use, resting blood pressure, routine biochemistry, hospitalisations) and harms associated with intervention. A nested qualitative study was conducted. RESULTS: We randomised 379 participants; 335 patients completed baseline assessments and 243 patients (intervention, n = 127; control, n = 116) completed 6-month assessments. The mean difference in change in physical component summary score from baseline to 6 months between the intervention group and control group was 2.4 arbitrary units (95% confidence interval -0.1 to 4.8 arbitrary units; p = 0.055). Participants in the intervention group had poor compliance (49%) and very poor adherence (18%) to the exercise prescription. The cost of delivering the intervention ranged from £463 to £848 per participant per year. The number of participants with harms was similar in the intervention (n = 69) and control (n = 56) groups. LIMITATIONS: Participants could not be blinded to the intervention; however, outcome assessors were blinded to group allocation. CONCLUSIONS: On trial completion the primary outcome (Kidney Disease Quality of Life Short Form, version 1.3, physical component summary score) was not statistically improved compared with usual care. The findings suggest that implementation of an intradialytic cycling programme is not an effective intervention to enhance health-related quality of life, as delivered to this cohort of deconditioned patients receiving haemodialysis. FUTURE WORK: The benefits of longer interventions, including progressive resistance training, should be confirmed even if extradialytic delivery is required. Future studies also need to evaluate whether or not there are subgroups of patients who may benefit from this type of intervention, and whether or not there is scope to optimise the exercise intervention to improve compliance and clinical effectiveness.

Although the benefits of exercise in the general population are well recognised, we do not know if offering cycling exercise during haemodialysis is an effective way to improve quality of life, and if this would be a cost-effective way to provide exercise training for this patient population. To determine whether or not this type of exercise training is effective, and provides value for money, this study compared cycling during haemodialysis treatment, three times per week for 6 months, with usual care that does not include routine delivery of any exercise training. Five regions of the UK were included in the study. We compared the results from the two groups at the start of the study and at 6 months, after correcting for age and diabetes status. We also assessed the economic impact of delivering the cycling during haemodialysis programme and interviewed people from different regions of the UK in both groups. The baseline assessments revealed a deconditioned population in the study. There was no difference in quality of life or any physical function measures between the group that performed cycling during haemodialysis and the usual-care group. Compliance with the exercise intervention was very poor. Interviews with patients showed that patient engagement with the exercise training was linked to the presence of an exercise culture, and leadership to provide this, in the renal unit. An economic evaluation showed that delivering cycling during haemodialysis would not be value for money when delivered to a deconditioned haemodialysis population. Ways to engage patients with exercise training during their haemodialysis treatment should be explored further.

Prospective Audit to Study urokinaSe use to restore Patency in Occluded centRal venous caTheters (PASSPORT 1).

OBJECTIVES: Tunnelled central venous catheters dysfunction can be defined as failure to provide blood flow above 200 mL/min during dialysis often caused by thrombosis. Although urokinase is used routinely for thrombolysis, there is wide variation in dose regimens. A multidisciplinary group was formed to address this issue and offer guidance. METHODS: Dialysis centres that used urokinase in the United Kingdom took part in a prospective study to determine the safety and outcomes of thrombolysis using agreed protocols. Data were collected anonymously from September 2017 until February 2018. Catheter blood flow was measured before and after the following interventions: catheter dwell or push locks with 12,500-50,000 IU or catheter infusion with 100,000-250,000 IU of urokinase. Interventions were repeated if the blood flow remained below 200 mL/min. RESULTS: 10 centres took part and recruited 200 patients; 45.5% were female and 54.5% were male with mean age of 63.6 (±15.2) years. The cumulative success rate for thrombolysis was 90.5% after first intervention, 97% after second intervention, and 99% after more than 2 interventions. Although there was trend towards benefit with dose increments, the success rate between push/dwell locks and high-dose infusion of urokinase was not significantly different (p = 0.069). Seventeen (8.5%) tunnelled central venous catheters were removed due to failure of treatment. No urokinase-related adverse events were reported. CONCLUSION: In this study, urokinase was safe and efficacious; there was no difference between dwell and push locks. There was some benefit with high-dose infusion of urokinase compared to the dwell and push lock.

How common are neurocognitive disorders in patients with chronic kidney disease and diabetes? Results from a cross-sectional study in a community cohort of patients in North Wales, UK.

OBJECTIVE: Chronic kidney disease (CKD) affects nearly 9% of global populations and is strongly associated with older age. Neurocognitive disorders (NCDs), which include mild cognitive impairment and dementia, are rising as a result of ageing populations throughout the world. This investigation's aim is to report the frequency of mild to major NCD in a clinical cohort of adults with mild to moderate CKD and diabetes. SETTING: Glan Clwyd District general Hospital, North Wales, UK. PARTICIPANTS: We enrolled 178 patients with CKD and diabetes, aged 55 years and over with an estimated glomerular filtration rate <60 >15 mL/min/1.73 m2, attending a specialist renal and diabetic outpatient clinic. OUTCOME MEASURES: Frequency of mild and major NCD and the association with the stage of CKD was assessed in all patients attending the specialist clinic. The diagnosis of NCD was based on patient and informant interview, case note review, neuropsychological assessment and application of Diagnostic and Statistical Manual of Mental Disorders version 5. RESULTS: This investigation found 86/178 (48%) of the cohort with an NCD ranging from mild (n=49) to major symptoms (n=37). No association was found with NCD and the stage of CKD. Mild and major NCD was associated poorer outcomes in several cognitive domains, including, language, executive, memory, fluency and attention function (p<0.05). CONCLUSIONS: This is the first UK investigation to report that cognitive changes occur in a significant number of older adults with CKD and diabetes. The unexpected finding was that prior to cognitive assessment, not any of the cohort had a pre-existing diagnosis of cognitive impairment, suggesting that the current prevalence and incidence rates of NCD in the general population are possibly significantly underestimated. Our findings also suggest that the cognitive function of patients with CKD should be screened and monitored routinely as part of their overall care management.

Nandrolone decanoate as anabolic therapy in chronic kidney disease: a randomized phase II dose-finding study.

BACKGROUND/AIMS: In patients with chronic kidney disease (CKD) receiving adequate erythropoietin therapy, the ideal dose of nandrolone decanoate (ND) to enhance muscle mass is not known. METHODS: In this phase II dose-finding study, 54 patients with CKD stage 5 were randomized to either low, medium or high doses of ND (50, 100 or 200 mg/week for 24 weeks, respectively, in males; doses halved in females), while 7 patients acted as non-randomized controls. The primary outcome measure was appendicular lean mass (ALM) by dual-energy X-ray absorptiometry. Fluid overload (hydration of the fat-free mass) and indicators of physical functioning were secondary measures. Harms were also recorded. Data were analysed using Quade's (1967) non-parametric analysis of covariance. RESULTS: ND increased ALM in a dose-responsive manner (change scores = 0.3 +/- 0.3 vs. 0.8 +/- 0.3 vs. 1.5 +/- 0.5 vs. 2.1 +/- 0.4 kg, control vs. low vs. medium vs. high dose groups, respectively, p < 0.001) with no increases in fluid overload but no consistent effect on physical functioning. The highest dose of ND (100 mg/week) was intolerable in females because of virilizing effects. CONCLUSION: If goals of future studies are to improve body composition, dosing of ND up to 200 mg/week in males and 50 mg/week in females should be investigated. However, to realize improvements in physical functioning, future phase III trials of ND may require additional interventions such as exercise training.

GFR estimation using cystatin C is not independent of body composition.

BACKGROUND: Cystatin C (CysC) is an endogenous marker of glomerular filtration rate (GFR) that is claimed to be unaffected by body composition. In this study, we tested this speculation. METHODS: In 77 patients with chronic kidney disease (mean age, 65.1 +/- 11.9 [SD] years; mean indexed GFR, 45.7 +/- 28.6 mL/min/1.73 m(2) [0.76 +/- 0.48 mL/s]), we evaluated kidney function (GFR) by means of inulin clearance. CysC level was determined by using a particle-enhanced turbidimetric immunoassay. Total lean (LM) and fat masses were measured by means of dual-energy x-ray absorptiometry. Multiple regression was used to analyze relationships between absolute GFR, LM, fat mass, demographic and anthropometric variables (age, sex, height, and weight), and CysC levels. Then prediction equations were built that included only CysC level or CysC level and LM. Their performance to predict absolute GFR was evaluated in a subset of patients with extreme body composition (LM or fat mass > +/-1 SD of the entire sample). RESULTS: Only absolute GFR and LM significantly explained variance in CysC levels, and an equation including LM explained more variance in absolute GFR than an equation including CysC level alone. Consequently, the equation including LM performed better than the equation with only CysC level, especially in patients with extreme body composition, showing reduced bias and improved limits of agreement and accuracy (71.4% versus 51.4% of patients' predicted GFR did not deviate by >30% of GFR). CONCLUSION: LM is a previously unrecognized, but important, factor affecting CysC level, and GFR estimation improves when including LM. CysC level is not independent of body composition, as previously assumed, and hence accounting for body composition improves CysC-based GFR estimation.

The Utility of the Mini-Addenbrooke's Cognitive Examination as a Screen for Cognitive Impairment in Elderly Patients with Chronic Kidney Disease and Diabetes.

BACKGROUND/AIMS: We tested the utility of the Mini-Addenbrooke's Cognitive Examination (M-ACE) in a cohort of older adults with chronic kidney disease (CKD) and diabetes. METHOD: The M-ACE was administered to 112 CKD and diabetes patients attending a nephrology clinic. Cognitive impairment was based upon patient, informant, and case review, neuropsychological assessment, and application of criteria for mild cognitive impairment (MCI) and the Diagnostic and Statistical Manual of Mental Disorders, fifth edition for dementia. The M-ACE was also compared to the Mini-Mental State Examination (MMSE). RESULTS: Upon assessment, 52 patients had normal cognitive function, 33 had MCI, and 27 had dementia. The area under the receiver operating curve for the M-ACE was 0.96 (95% CI 0.95-1.00). The sensitivity and specificity for a dementia diagnosis were 0.96 and 0.84 at the cut point <25 and 0.70 and 1.00 at the cut point <21. Mean M-ACE scores differed significantly between normal, demented, and MCI groups (p < 0.001), and compared to the MMSE, the M-ACE did not suffer from ceiling effects. CONCLUSION: The M-ACE is an easily administered test with good sensitivity and specificity to capture and assist in the diagnosis of MCI or dementia in patients with CKD and diabetes.
