Continuous Glucose Monitoring-Guided Insulin Administration in Long-Term Care Facilities: A Randomized Clinical Trial.

OBJECTIVES: To evaluate the efficacy of real-time continuous glucose monitoring (rt-CGM) in adjusting insulin therapy in long-term care facilities (LTCF). DESIGN: Prospective randomized clinical trial. SETTINGS AND PARTICIPANTS: Insulin-treated patients with type 2 diabetes (T2D) admitted to LTCF. METHODS: Participants in the standard of care wore a blinded CGM with treatment adjusted based on point-of-care capillary glucose results before meals and bedtime (POC group). Participants in the intervention (CGM group) wore a Dexcom G6 CGM with treatment adjusted based on daily CGM profile. Treatment adjustment was performed by the LTCF medical team, with a duration of intervention up to 60 days. The primary endpoint was difference in time in range (TIR 70-180 mg/dL) between treatment groups. RESULTS: Among 100 participants (age 74.73 ± 11 years, 80% admitted for subacute rehabilitation and 20% for nursing home care), there were no significant differences in baseline clinical characteristics between groups, and CGM data were compared for a median of 17 days. There were no differences in TIR (53.38% ± 30.16% vs 48.81% ± 28.03%, P = .40), mean daily mean CGM glucose (184.10 ± 43.4 mg/dL vs 190.0 ± 45.82 mg/dL, P = .71), or the percentage of time below range (TBR) <70 mg/dL (0.83% ± 2.59% vs 1.18% ± 3.54%, P = .51), or TBR <54 mg/dL (0.23% ± 0.85% vs 0.56% ± 2.24%, P = .88) between rt-CGM and POC groups. CONCLUSIONS AND IMPLICATIONS: The use of rtCGM is safe and effective in guiding insulin therapy in patients with T2D in LTCF resulting in a similar improvement in glycemic control compared to POC-guided insulin adjustment.

Assessment of Glycemic Control by Continuous Glucose Monitoring, Hemoglobin A1c, Fructosamine, and Glycated Albumin in Patients With End-Stage Kidney Disease and Burnt-Out Diabetes.

OBJECTIVE: Patients with diabetes and end-stage kidney disease (ESKD) may experience "burnt-out diabetes," defined as having an HbA1c value <6.5% without antidiabetic therapy for >6 months. We aim to assess glycemic control by continuous glucose monitoring (Dexcom G6 CGM) metrics and glycemic markers in ESKD patients on hemodialysis with burnt-out diabetes. RESEARCH DESIGN AND METHODS: In this pilot prospective study, glycemic control was assessed by continuous glucose monitoring (CGM), HbA1c measures, and glycated albumin and fructosamine measurements in patients with burnt-out diabetes (n = 20) and without a history of diabetes (n = 20). RESULTS: Patients with burnt-out diabetes had higher CGM-measured daily glucose levels, lower percent time in the range 70-180 mg/dL, higher percent time above range (>250 mg/dL), and longer duration of hyperglycemia >180 mg/dL (hours/day) compared with patients without diabetes (all P < 0.01). HbA1c and fructosamine levels were similar; however, patients with burnt-out diabetes had higher levels of glycated albumin than did patients without diabetes. CONCLUSIONS: The use of CGM demonstrated that patients with burnt-out diabetes have significant undiagnosed hyperglycemia. CGM and glycated albumin provide better assessment of glycemic control than do values of HbA1c and fructosamine in patients with ESKD.

Diabetic retinopathy in African-Americans with end-stage kidney disease: a cross-sectional study on prevalence and impact on quality of life.

INTRODUCTION: The prevalence, severity, and quality of life (QoL) impact of diabetic retinopathy (DR) among African-Americans (AAs) with end-stage kidney disease (ESKD) undergoing dialysis are unknown. RESEARCH DESIGN AND METHODS: A cross-sectional study was conducted on 93 AA adults with diabetes and ESKD. The diagnosis of DR was based on a review of medical records and/or a positive photograph with a portable hand-held device reviewed by both artificial intelligence software and a retinal specialist. QoL, physical disability social determinants of health (SDoHs) were assessed by standardized questionnaires. RESULTS: The prevalence of DR was 75%, with 33% of participants having mild, 9.6% moderate and 57.4% severe DR. A total of 43% had normal visual acuity; 45% had moderate visual impairment; and 12% had severe visual impairment. We found a high burden of disease, multiple SDoH challenges, and low QoL and general health among patients with ESKD. The presence of DR had no significant impact on physical health and QoL compared with participants without DR. CONCLUSIONS: DR is present in 75% of AA patients with diabetes and ESKD on haemodialysis. ESKD has a significant burden on general health and QoL; however, DR has a minor additional impact on the overall physical health and QoL in people with ESKD.

Anastomotic biliary stricture following liver transplantation and management analysis: 15 years of experience at a high-volume transplant center.

INTRODUCTION: The occurrence of anastomotic biliary stricture (BS) remains an essential issue following liver transplantation (LT). The present study aimed to compare our findings regarding the incidence of anastomotic BS to what is known. METHODS: The present study is a single-center, retrospective cohort study of a total number of 717 consecutive patients (426 men and 291 women) who had undergone LT from January 2001 to March 2016. Multivariable Cox regression analysis was conducted to evaluate the risk factors associated with anastomotic BS development. RESULTS: Post-transplant anastomotic BS developed in 70 patients (9.8%). In the Cox multivariate analysis (a stepwise forward conditional method), factors including biliary leak (hazard ratio [HR]: 6.61, 95% confidence interval [CI]: 3.08-17.58, p < 0.001), hepatic artery thrombosis (HR: 2.29, 95% CI: 1.03-5.88; p = 0.003), and acute rejection (HR: 2.18, 95% CI: 1.16-3.37; p = 0.006) were identified as independent risk factors for the development of anastomotic BS. Surgery in 6 cases (66.7%), followed by endoscopic retrograde cholangiopancreatography (ECRP) with a metal stent in 18 cases (62.1%), percutaneous transhepatic biliary drainage in 9 (20.9%), and ERCP with a single plastic stent in 8 (18.2%), had the highest effectiveness rates in the management of BS, respectively. CONCLUSIONS: Risk factors including biliary leak, hepatic artery thrombosis, and acute rejection were independently associated with an anastomotic BS. ERCP with a metal stent may be considered as an effective treatment procedure with a relatively low complication rate in the management of benign post-LT anastomotic BS.

Local intramuscular transplantation of autologous bone marrow mononuclear cells for critical lower limb ischaemia.

BACKGROUND: Peripheral arterial disease is a major health problem, and in about 1% to 2% of patients, the disease progresses to critical limb ischaemia (CLI), also known as critical limb-threatening ischaemia. In a substantial number of individuals with CLI, no effective treatment options other than amputation are available, with around a quarter of these patients requiring a major amputation during the following year. This is the second update of a review first published in 2011. OBJECTIVES: To evaluate the benefits and harms of local intramuscular transplantation of autologous adult bone marrow mononuclear cells (BMMNCs) as a treatment for CLI. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 8 November 2021. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) of CLI in which participants were randomly allocated to intramuscular administration of autologous adult BMMNCs or control (either no intervention, conventional conservative therapy, or placebo). DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes of interest were all-cause mortality, pain, and amputation. Our secondary outcomes were angiographic analysis, ankle-brachial index (ABI), pain-free walking distance, side effects and complications. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS: We included four RCTs involving a total of 176 participants with a clinical diagnosis of CLI. Participants were randomised to receive either intramuscular cell implantation of BMMNCs or control. The control arms varied between studies, and included conventional therapy, diluted autologous peripheral blood, and saline. There was no clear evidence of an effect on mortality related to the administration of BMMNCs compared to control (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.15 to 6.63; 3 studies, 123 participants; very low-certainty evidence). All trials assessed changes in pain severity, but the trials used different forms of pain assessment tools, so we were unable to pool data. Three studies individually reported that no differences in pain reduction were observed between the BMMNC and control groups. One study reported that reduction in rest pain was greater in the BMMNC group compared to the control group (very low-certainty evidence). All four trials reported the rate of amputation at the end of the study period. We are uncertain if amputations were reduced in the BMMNC group compared to the control group, as a possible small effect (RR 0.52, 95% CI 0.27 to 0.99; 4 studies, 176 participants; very low-certainty evidence) was lost after undertaking sensitivity analysis (RR 0.52, 95% CI 0.19 to 1.39; 2 studies, 89 participants). None of the included studies reported any angiographic analysis. Ankle-brachial index was reported differently by each study, so we were not able to pool the data. Three studies reported no changes between groups, and one study reported greater improvement in ABI (as haemodynamic improvement) in the BMMNC group compared to the control group (very low-certainty evidence). One study reported pain-free walking distance, finding no clear difference between BMMNC and control groups (low-certainty evidence). We pooled the data for side effects reported during the follow-up, and this did not show any clear difference between BMMNC and control groups (RR 2.13, 95% CI 0.50 to 8.97; 4 studies, 176 participants; very low-certainty evidence). We downgraded the certainty of the evidence due to the concerns about risk of bias, imprecision, and inconsistency. AUTHORS' CONCLUSIONS: We identified a small number of studies that met our inclusion criteria, and these differed in the controls they used and how they measured important outcomes. Limited data from these trials provide very low- to low-certainty evidence, and we are unable to draw conclusions to support the use of local intramuscular transplantation of BMMNC for improving clinical outcomes in people with CLI. Evidence from larger RCTs is needed in order to provide adequate statistical power to assess the role of this procedure.
