Optimal management can prevent the onset of complications and improve patients’ quality of life. Objectives: To determine the frequency of self-monitoring of blood glucose and to describe the errors found during self-monitoring in diabetic patients followed at the Endocrinology Department of Donka University Hospital in Guinea. Materials and methods: Descriptive cross-sectional study carried out between August and September 2020 involving diabetic patients followed up at the Endocrinology and Diabetology Department of the Donka National Hospital, CHU Conakry. Results: A total of 301 patients were enrolled, with an average age of 44.24 ± 21.01 years. 64.12% were female. Type 2 diabetes predominated in 64% of cases. The mean duration of diabetes was 6.14 ± 4.67 years, and 75.08% of patients lived in urban areas. Patients were on insulin in 36.21% of cases, insulin and biguanides (26.25%), hypoglycemic sulfonamide and biguanides (19.27%) and biguanides in 18.27% of cases. The frequency of self-monitoring of blood glucose was 43%, and 38% of patients made errors, notably reusing lancets (60%), not checking the expiration date (55.65%) and not washing their hands (48%). Conclusion: This study shows that self-monitoring of blood glucose is not performed by the majority of patients. Numerous errors were identified during blood glucose testing. Continued therapeutic education on the use of blood glucose meters will help empower patients and improve their quality of life.展开更多

Methods: A total of 111 nursing school students were randomized into three groups, two intervention groups (a two-month intervention group, n = 34, and a four-month intervention group, n = 35) and a control group (n = 34). The intervention groups conducted lifestyle self-monitoring in conjunction with a 15-minutes group work for either two or four months. The primary outcome measure was Rome II criteria for IBS. Other outcome measures were the Hospital Anxiety and Depression Scale (HADS) and the Gastrointestinal Symptom Rating Scale (GSRS). They were assessed at the baseline and the end of both of the intervention periods. Analysis was conducted as intention-to-treat. Results: The prevalence of IBS did not change significantly after the intervention in any of the groups. The HAD-A score, a subscale of the HADS score for anxiety, decreased 1.4 points in the two-month intervention group (p = 0.02) and 2.3 points in the four-month intervention group of (p = 0.01) after intervention. The average GSRS decreased 0.2 points in the control group (p = 0.05) and 0.3 points in the four-month intervention group (p < 0.01). Conclusions: Lifestyle self-monitoring for two or four months did not reduce the prevalence of the IBS significantly, but it did decrease anxiety and improved the QOL related to gastrointestinal symptoms in female nursing school students.展开更多

The impact of depressive symptoms in patients with type 2 diabetes on self-care and glycosylated hemoglobin (HbA1c) was explored. Background: Depression is known to decrease compliance with most medical regimens. This study investigated depression’s effects on different aspects of compliance with a diabetic regimen. Design: Cross-sectional, correlational, quantitative study. Methods: A cross-sectional study was conducted using data from 126 patients with type 2 diabetes from a diabetes education class. Participants completed depression and self-care inventories. Regression analyses were performed to determine the impact of depressive symptoms on the dependent variables of compliance to diabetes self-care and HbA1c levels. Results: Levels of depression were significantly and inversely correlated with 1) total self-care scores, accounting for 5.1% of the variance, 2) compliance with glucose self-monitoring accounting for 3.4% of the variance, and 3) compliance with diet accounting for 9.3% of the variance. Levels of depression were not significantly related to HbA1c. Conclusions: Depressive symptoms are associated with poorer total self-care, poorer glucose self-monitoring, and poorer dietary compliance in type 2 diabetes patients. Depression scores help explain variations in patients’ performance with aspects of compliance to diabetes management. Relevance to clinical practice: Administering a personality questionnaire, perhaps on the initial visit could enable the clinical to know which aspects of diabetes self-care are affected by depression, which would enable the clinician to more closely monitor melancholic patients in the effort to improve glycemic control and medical outcomes.展开更多

Continuous and real-time monitoring of blood glucose plays a key role for the people with diabetes,which can help them to control glucose concentration more effectively. However,current blood glucose monitoring methods require blood by needle-pricking,which limit the detection frequency. It is necessary to develop non-invasive blood glucose monitoring methods to achieve the ideal therapeutic and management of diabetes. In this paper,the developments and challenges of non-invasive blood glucose monitoring technologies in recent years are reviewed. And the bottleneck and the developing trends are also analyzed.展开更多
