Lower Extremity Arterial Disease in Patients with Type 2 Diabetes: Prevalence and Associated Factors at the Libreville University Hospital Center

Introduction: Lower extremity arterial disease in diabetic patients has distinct characteristics. Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]

Investigation and analysis of lower extremity arterial disease in hospitalized elderly type 2 diabetic patients

Background:The risk of lower extremity arterial disease (LEAD) is increased in diabetic patients.LEAD in diabetic patients occurs earlier and is often more severe and diffuse;however,it is largely underdiagnosed and untreated.The purposes of this study were to investigate and analyze LEAD situation of hospitalized elderly type 2 diabetic patients.Methods:The ankle-brachial index (ABI) was used to screen LEAD in hospitalized elderly type 2 diabetic patients.The patients were divided into 5 groups based on the screening results:non-LEAD group and LEAD group;the LEAD group was divided into mild stenosis group,moderate stenosis group,and severe stenosis group.Results:The percentage of patients who had LEAD was 43%.Significant difference in age,diabetes duration,peak velocity,microalbuminuria,and vibratory sensory neuropathy was observed between patients with and without LEAD;regression analysis showed that urinary albumin and vibratory sensory neuropathy were independent risk factors for LEAD.Significant difference in age,body mass index (BMI),peak velocity,urinary albumin,and high-density lipoprotein cholesterol (HDL-C) was observed between mild stenosis group,moderate stenosis group,and severe stenosis group;regression analysis showed that urinary albumin,BMI,and HDL-C were independent risk factors for accelerating vascular stenosis.Conclusions:The incidence of LEAD in hospitalized elderly type 2 diabetic patients is high;age,diabetes duration,peak velocity,BMI,urinary microalbumin,vibratory sensory neuropathy,and HDL-C are the maior risk factors for LEAD.Active control of risk factors is helpful to reduce or delay LEAD.

Effect of combining music media therapy with lower extremity exercise on elderly patients with diabetes mellitus

Objective:To evaluate the compliance with lower extremity exercise and blood circulation in the feet of elderly diabetics following a combination of music media therapy and a lower extremity exercise regimen.Method:The 72 elderly diabetic patient subjects were divided into two groups:control group(n=38)and intervention group(n=34).Both groups were exposed to the same comprehensive therapy to control glucose levels.While the control group was given the lower extremity exercise,the intervention group received the extremity exercise in addition to the music media.Result:After three months of intervention,the adherence to the lower extremity exercise regimen in the intervention group was significantly higher than that of the control group(p<0.05).Additionally,following six months of treatment,both the dorsal artery peak values and ankle-brachial indices(ABIs)showed significant differences between the control and intervention groups(p<0.05).Conclusion:Music media treatment combined with lower extremity exercise can both significantly increase the extent of exercise compliance of elderly patients suffering from diabetes mellitus,as well as improve blood circulation in their feet.

Lower extremity amputations and long-term outcomes in diabetic foot ulcers:A systematic review

BACKGROUNDDiabetes mellitus causes a large majority of non-traumatic major and minoramputations globally. Patients with diabetes are clinically complex with amultifactorial association between diabetic foot ulcers (DFU) and subsequentlower extremity amputations (LEA). Few studies show the long-term outcomeswithin the cohort of DFU-associated LEA.AIMTo highlight the long-term outcomes of LEA as a result of DFU.METHODSPubMed/MEDLINE and Google Scholar were searched for key terms, “diabetes”,“foot ulcers”, “amputations” and “outcomes”. Outcomes such as mortality, reamputation,re-ulceration and functional impact were recorded. Peer-reviewedstudies with adult patients who had DFU, subsequent amputation and follow upof at least 1 year were included. Non-English language articles or studiesinvolving children were excluded.RESULTSA total of 22 publications with a total of 2334 patients were selected against theinclusion criteria for review. The weighted mean of re-amputation was 20.14%,29.63% and 45.72% at 1, 3 and 5 years respectively. The weighted mean of mortality at 1, 3 and 5 years were 13.62%, 30.25% and 50.55% respectively withsignificantly higher rates associated with major amputation, re-amputation andischemic cardiomyopathy.CONCLUSIONPrevious LEA, level of the LEA and patient comorbidities were significant riskfactors contributing to re-ulceration, re-amputation, mortality and depreciatedfunctional status.

Paper Clinical Value of Color Doppler Ultrasonography in Diagnosis of Lower Extremity Arterial Disease of Diabetes Patients

Objective: To evaluate the diagnostic value of color Doppler ultrasound in the diagnosis of diabetic lower extremity vascular diseases. Methods: 48 patients with diabetic lower extremity vascular disease admitted in our hos-pital from September 2018 to September 2019 were included in the study and divided into the observation group, and another 48 patients with the same period of health examination in our hospital were included in the study and divided into the control group. Both groups used color Doppler ultrasound to detect the blood flow of lower extremity vessels. The incidence of blood flow, vascular diameter and stenosis, occlusion and arteriosclerosis of the lower extremity were observed. Results: The blood flow and vascular di-ameter of the lower extremity in the observation group were significantly lower than those in the control group (p < 0.05). The incidence of vascular stenosis, vascular occlusion, thrombus, intimal thickening and plaque in the observation group was 85.42%, 22.92%, 10.42% and 93.75% respectively, which was significantly higher than that in the control group was 10.42%, 0.00%, 0.00% and 14.58% (p < 0.05). The incidence of lower extremity vascular lesions in the observation group was significantly higher than that in the control group (p < 0.05). Conclusion: Color Doppler ultrasound is of high diagnostic value in the diagnosis of diabetic lower extremity vascular diseases, and can be used to determine the blood flow of the lower extremity and the inner diameter of popliteal artery, thigh artery, dorsalis pedis artery and so on. At the same time, it can also clearly show the specific situation of vascular occlusion, arteriosclerosis and thrombosis, which is of great signif-icance for the prevention and diagnosis of lower extremity vascular lesions, and can provide the basis for the treatment of lower extremity vascular lesions.

To Explore the Relationship between Lower Extremity Vascular Sclerosis and Osteoporosis in Elderly Men with Type 2 Diabetes Mellitus

Objective: To investigate the correlation between lower extremity vascular sclerosis and osteoporosis in elderly men with type 2 diabetes mellitus. Methods: A total of 359 elderly male patients with type II diabetes hospitalized in the First Affiliated Hospital of Chongqing Medical University from January 2018 to June 2023 were retrospectively collected. According to the BMD (Bone Density Value), the patients were categorized into osteoporotic (T ≤ -2.5, n = 248) and non-osteoporotic groups (T > -2.5, n = 111). T test and Chi-square test were used to evaluate the differences in clinical data, biochemical markers and ABI between two groups. Multivariate logistic regression was used to analyze the risk factors of osteoporosis in elderly men with type 2 diabetes mellitus. Results: Compared with the non-osteoporotic group, the differences in diabetes course, systolic blood pressure, ABI, BMI, uric acid, triglyceride, and HDL in the osteoporotic group were statistically significant (P < 0.05). Logistic multivariate regression analysis showed that lower extremity vascular sclerosis was an independent risk factor for osteoporosis in elderly men with type 2 diabetes mellitus (P Conclusion: Atherosclerosis of the lower extremities in elderly men with T2DM is closely related to osteoporosis, and can lead to a decrease in bone mass, and an increase in osteoporosis.

Effect of Buerger’s Exercises on Improving Peripheral Circulation: A Systematic Review

The aim of this study was to systematically review the evidence for the effectiveness of Buerger’s exercise on the peripheral circulation or diabetic foot ulceration. A systematic search and 18 electronic databases were conducted. The intervention was predominantly focused on Buerger’s exercise as an outcome. Due to high heterogeneity, data were synthesized in a narrative format rather than by statistical methods. Nine studies that covered 592 participants were selected in the analysis, of which 8 of the 9 found an effect of Buerger’s exercise on peripheral circulation. The positive effects were indicative of improving blood flow, walking ability, reducing necrosis, reducing venous embolism, pain, swelling, cyanosis and the bed-rest times. However, the study design and quality appraisal were limited to Jadad score 2 and the sample size was small. Findings provide some evidence of the beneficial effects of Buerger’s exercises. It was seen as a low cost and low risk physical activity that most diabetic patients could undertake at home. This review highlighted a need for further investigation of standardized procedures of Buerger’s exercises. More high quality studies on the prevention of diabetic foot are required regarding Buerger’s exercises.
