Enhancing gestational diabetes management in Filipino patients: Evaluating the impact of education on knowledge, attitude, and pregnancy outcomes at a Tertiary Medical Center

Introduction@#Patient education is integral in the management of gestational diabetes mellitus (GDM), a common pregnancy complication that may cause adverse perinatal outcomes. This study evaluated the effect of diabetes education on the knowledge and attitude among patients with GDM, comparing pre- vs post-diabetes session scores and determining pregnancy outcomes.@*Methodology@#A one-group pre-test and post-test experimental design study was conducted on 75 patients after one- session diabetes counseling using the Gestational Diabetes Mellitus Knowledge Questionnaire (GDMKQ) and the third version of the Diabetes Attitude Scale (DAS-3).@*Results@#Of the 75 subjects, 84% exhibited adequate knowledge of diabetes. Post-education, a significant increase in the total scores was seen among those less than 35 years of age (p-value: 0.003), both employed and unemployed (p-value: 0.0.026, 0.047, respectively), with a secondary level of education (p-value: 0.014) and multigravid (p-value: 0.015). An overall median positive attitude score of 3.6 was documented. For neonatal outcomes, no adverse events existed. For maternal outcomes, 17.9% had elevated fasting blood glucose while 7.1% had elevated 2-hour post-glucose tolerance test.@*Conclusion@#Diabetes education improves patient’s knowledge but not their attitude. Hence, improvement in attitude interventions should be incorporated into the current diabetes education program.

Health literacy and control in the medical encounter: a mixed-methods analysis.

BACKGROUND: Physician-patient communication can be described according to 4 prototypes of control--paternalism, mutuality, consumerism, or default. Patients with inadequate health literacy skills may be less-active participants in their care and more likely to have paternalistic encounters. METHODS: Two independent coders analyzed 31 transcribed outpatient medical visits between physicians and African American patients with diabetes according to the 4 prototypes of control. Differences in communication and the balance of power by level of patients' health literacy were analyzed by quantitative and qualitative methods. RESULTS: Fourteen patients (45%) had inadequate health literacy, and most of them (N=8, 57%) had paternalistic encounters. Among patients with marginal or adequate health literacy skills, only 4 (23%) had paternalistic visits (p = .06), and encounters marked by mutuality were most common (N= 9, 53%). CONCLUSION: Patients with inadequate health literacy appear more likely to have paternalistic interactions with their physicians.

Serum homocysteine, folate, vitamin B12 levels and arterial stiffness in diabetic patients: which of them is really important in atherogenesis?

AIM: Hyperhomocystinaemia is associated with macro- and microangiopathic diabetic complications. However, the role of homocysteine (Hcy), serum folate, and vitamin B12 level in the development of premature vascular damage in type 2 diabetic patients is not clear. The present study was designed to assess the relationship between total Hcy, folate, and vitamin B12 levels and arterial stiffness, an early marker of generalized atherosclerosis. METHODS: As many as 86 subjects with type 2 diabetes mellitus were studied. All participants were evaluated for glucose, HbA(1C), lipid profile, hs-CRP, endothelin, Hcy, vitamin B12, and folate. Pulse wave velocity (PWV) and augmentation index (AI) were performed as a non-invasive recording and computer analysis of the two artery sites pressure waveform using SphygmoCor (version 7.1, AtCor Medical, Sydney, Australia). RESULTS: Hcy was significantly positively associated with age, serum creatinine, and vitamin B12 levels. No association between Hcy and folate was observed. The Hcy concentration was significantly positively associated with PWV (r = 0.540, p < 0.0001) and AI (r = 0.390, p < 0.0001). In a general linear model of PWV, Hcy emerged as an independent predictor of PWV even after controlling for age, creatinine, vitamin B12, and folate levels. In a multiple linear regression analysis, the association between Hcy and arterial stiffness was independent of traditional cardiovascular risk factors. Vitamin B12 levels were significantly inversely associated with tHcy (r = - 0.263, p = 0.015) and marginally associated with PWV(r = - 0.212, p = 0.052). Significant associations between folate levels and PWV were not detected. CONCLUSIONS: The results lend support to the hypothesis that elevated Hcy may have a key role in the development of atherogenesis in diabetic patients. Additionally, vitamin B12 is significantly associated with tHcy concentrations and is identified as a marginally independent correlate of PWV in diabetic patients in the absence of folate deficiency.

Effect of homocysteine-lowering therapy on arterial elasticity and metabolic parameters in metformin-treated diabetic patients.

Metformin may affect the risk of atherothrombotic disease. However, metformin increases levels of homocysteine (Hcy), considered an independent risk factor for atherosclerosis. We evaluate whether homocysteine-lowering has a beneficial effect on arterial elasticity and metabolic parameters in metformin-treated diabetic patients. In double-blind, placebo-controlled study, 60 diabetic patients treated with high dose of metformin were randomly assigned to receive daily oral supplementation with folate (1000 mcg), vitamins B12 (400 mcg) and B6 (10mg) (group 1) or placebo (group 2). Lipid profile, HbA1C, insulin, C-peptide, hs-CRP, vitamin B12, folic acid, homocysteine, endothelin, homeostasis model assessment-insulin resistance (HOMA-IR) were measured. Arterial elasticity was evaluated using pulse wave contour analysis (HDI CR 2000, Eagan, MN). The two groups were similar at baseline in terms of hemodynamic and arterial elasticity parameters. After a 4-month small artery elasticity index (SAEI) was significantly greater in patients who received Hcy-lowering agents than in the placebo group: 4.3+/-2.04 ml/mm Hg x 100 versus 3.2+/-1.1 ml/mm Hg x 100, p=0.01. Post-treatment vitamin B12 and folic acid levels were greater in group 1 versus group 2: 738.1+/-279.9 pg/ml versus 566.1+/-167.4 pg/ml, p=0.007 and 14.9+/-4.8 ng/ml versus 8.3+/-2.9 ng/ml, p<0.0001, respectively. Hcy level decreased significantly in the treatment group from 10.0+/-4.4 to 7.6+/-2.5 micromol/l, p=0.002 and did not change in placebo group (p=0.9). Hcy-lowering therapy improved small arterial elasticity in diabetic patients treated with high dose of metformin. The improvement was associated with a decrease in Hcy as well as an increase in folic acid and vitamin B12. These findings suggest that Hcy-lowering may have beneficial vascular effect in metformin-treated diabetic patients.
