The effects of aging and frailty on inpatient glycemic control by continuous glucose monitoring in patients with type 2 diabetes.

BACKGROUND: Older adults with diabetes in the hospital are generally managed similarly to younger adults, however, it is unknown if the degree of frailty can affect glucose control among hospitalized patients. METHODS: We examined glycemic parameters derived from continuous glucose monitoring (CGM) in older adults with type 2 diabetes and frailty who were hospitalized in non-acute settings. Data was pooled from 3 prospective studies using CGM including 97 patients wearing Libre CGM sensors and 166 patients wearing Dexcom G6 CGM. Glycemic parameters (time in range (TIR) 70-180; time below range (TBR) <70 and 54 mg/dl) by CGM were compared between 103 older adults ≥60 years and 168 younger adults <60 years. Frailty was assessed using validated laboratory and vital signs frailty index FI-LAB (n = 85), and its effect on hypoglycemia risk was studied. RESULTS: Older adults, as compared to younger adults, had significantly lower admission HbA1c (8.76% ± 1.82 vs. 10.25% ± 2.29, p < 0.001), blood glucose (203.89 ± 88.65 vs. 247.86 ± 124.17 mg/dl, p = 0.003), mean daily BG (173.9 ± 41.3 vs. 183.6 ± 45.0 mg/dl, p = 0.07) and higher percent TIR 70-180 mg/dl (59.0 ± 25.6% vs. 51.0 ± 26.1%, p = 0.02) during hospital stay. There was no difference in hypoglycemia occurrence between older and younger adults. Higher FI-LAB score was associated with higher % CGM < 70 mg/dl (0.204) and % CGM < 54 mg/dl (0.217). CONCLUSION: Older adults with type 2 diabetes have better glycemic control prior to admission and during hospital stay compared to younger adults. Frailty is associated with longer presence of hypoglycemia in non-acute hospital settings.

Transanal irrigation for the treatment of neuropathic bowel dysfunction.

INTRODUCTION: Children with spinal cord lesions very often experience bowel dysfunction, with a significant impact on their social activities and quality of life. Our aim was to evaluate the efficacy of the Peristeen transanal irrigation (TI) system in patients with neuropathic bowel dysfunction (NBD). MATERIAL AND METHODS: We prospectively reviewed 40 children with spina bifida and NBD who did not respond satisfactorily to conventional bowel management and were treated with the Peristeen TI system. Dysfunctional bowel symptoms, patient opinion and level of satisfaction were analysed before and during TI treatment using a specific questionnaire. RESULTS: Thirty-five children completed the study. Mean patient age and follow up were 12.5 years (6-25) and 12 months (4-18), respectively. Average irrigation frequency and instillation volume were once every 3 days and 616ml (200-1000), respectively. Bowel dysfunction symptoms including faecal incontinence improved significantly in all children. Patient opinion of intestinal functionality improved from 2.3±1.4 to 8.2±1.5 (P<0.0001) and mean grade of satisfaction with the Peristeen system was 7.3. Patient independence also improved from 28 to 46% and no adverse events were recorded. CONCLUSIONS: TI should be used as a first therapeutic approach in those children with NBD who do not respond to conservative or medical bowel management before other more invasive treatment modalities are considered. The Peristeen system is as effective as other TI methods, but it is easy to learn, safe and increases the patient's independence.
