Evaluation of the responsiveness of Short Form-12 Health Survey version 2 (SF-12v2) in Chinese patients with hypertension in primary care.

PURPOSE: There is limited evidence on the responsiveness of the Short Form-12 Health Survey version 2 (SF-12v2) in hypertensive patients. This study aimed to evaluate both the responsiveness of the SF-12 measures in Chinese hypertensive patients. METHODS: A prospective longitudinal study was conducted on hypertensive patients managed in public primary care clinics between 2012 and 2013. A total of 583 and 431 patients were surveyed and completed SF-12v2 at baseline and at 12-month follow-up interviews, respectively. Using global rating of change scale as an external anchor, the responsiveness was assessed by linear mixed effect models, multiple linear regression models, and receiver operating characteristic (ROC) curve analysis. RESULTS: SF-12v2 managed to detect negative changes among hypertensive patients in worsened general health group but failed to identify changes among hypertensive patients in improved general health group. Meanwhile, some domains of SF-12v2 detected a significant difference in difference between patients of worsened and stable/improved group and between patients of stable and improved group, but none of the domains and the summary scales reached the recommended standard of 0.7 in any comparisons in ROC analysis. CONCLUSIONS: The SF-12v2 was responsive to worsening of HRQOL but not to improvements in HRQOL among hypertensive patients. The overall responsiveness of SF-12v2 in hypertensive patients is unsatisfactory. Further studies are needed to identify HRQOL measures with good internal and external responsiveness for hypertensive patients.

The effects of education based on the Roy adaptation model on medication adherence and psychosocial adjustment in hypertensive patients.

BACKGROUND AND AIM: Patient education utilizing nursing theory can enhance patient adherence to treatment and potentially decrease mortality rates. The objective of this investigation was to assess the impact of Roy's adaptation Model-focused education on medication adherence and psychosocial compliance in hypertensive patients. METHODS: This study was conducted in N = 60 hypertensive patients (n = 30 control group and n = 30 experimental group) based on a randomized controlled trial design. In the pre-test phase of the study, data was collected using the Patient Information Form, the medication adherence rating scale (MARS), and the psychosocial adjustment to illness scale-self-report (PAIS-SR). After the pre-test phase, the experimental group received hypertension education and the "Hypertension Education Booklet" for a duration of four weeks. No education was provided to the control group patients; only routine follow-ups were conducted. In the post-test phase (after four weeks), both groups were reassessed using MARS and PAIS-SR. After completing the study, the control group patients who volunteered to participate in the education were provided with hypertension education and the "Hypertension Education Booklet" for a duration of four weeks (n = 4). RESULTS: The post-test measurements of patients in the experimental group (after 4 weeks of education) revealed an increase in the mean MARS scores (6.50 ± 0.86) and a significant decrease in the total and subscale mean scores of PAIS-SR (24.12 ± 7.08) (p < 0.05). No changes were observed in the control group patients. CONCLUSION: The results of the study revealed that the education based on the Roy's Adaptation Model increased hypertensive individuals' medication adherence and physiological, psychological, and social adjustment to the disease. RELEVANCE TO CLINICAL PRACTICE: The education based on the Roy's Adaptation Model seems to be effective in increasing patients' adherence to treatment and adjustment to the disease. This model can be used in various diseases and societies, since it increases adjustment to the disease and the effectiveness of treatment.

Interaction effect of type 2 diabetes mellitus and hypertension on left atrial function: a three-dimensional echocardiography study.

Background: Type 2 diabetes mellitus (T2DM) and hypertension (HT) often coexist and contribute to left atrial (LA) functional abnormalities. The aim of the present study was to explore whether there is a potential interaction effect between T2DM and HT on LA function. Methods: A total of 135 patients (45 with T2DM only, 45 with HT only, and 45 with both T2DM and HT) were enrolled and compared to 45 age- and sex-matched controls. LA volume fraction, including LA ejection fraction (LAEF), LA expansion index (LAEI), LA passive emptying fraction (LAPEF), and LA active emptying fraction (LAAEF), and strain parameters, including LA reservoir longitudinal strain (LASr), LA conduit longitudinal strain (LAScd), and LA contraction longitudinal strain (LASct), were obtained using three-dimensional echocardiography (3DE). Results: Patients with T2DM had significantly more impaired LA reservoir and conduit functions compared to those without T2DM (P<0.05), and patients with HT had a significantly more impaired LA reservoir function, conduit function, and booster pump function compared to those without HT (P<0.05). Two-way analysis of variance showed that there were significant additive interaction effects between T2DM and HT with respect to LASr (PT2DM + HT =0.002) and LAScd (PT2DM + HT =0.001). Generalized linear model demonstrated that T2DM + HT had a greater relative contribution than either T2DM or HT alone to the LA strain indexes, even after adjustment for other confounders (LASr, ßT2DM + HT =-3.931, 95% CI: -6.237 to -1.624, P=0.001; LAScd, ßT2DM + HT=-3.781, 95% CI: -5.653 to -1.908, P<0.001). Conclusions: Both T2DM and HT had an adverse effect on LA function. The coexistence of both conditions further impaired LA performance in an additive interaction fashion.

Is There a Clinically Meaningful Change in the Blood Pressure of Osteoarthritis Patients with Comorbid Hypertension During the Course of Balneotherapy?

BACKGROUND: Balneotherapy (BT) is a treatment modality that uses the physical and chemical effects of water, including thermomineral, acratothermal, and acratopegal waters. It has many effects on cardiovascular system. AIM: The aim of the study is to investigate the effects of 3-week BT on blood pressure of osteoarthritis (OA) patients with no hypertension (HT), and controlled or uncontrolled HT. MATERIALS AND METHODS: The OA patients (n = 270) were divided into three groups: No HT, controlled HT, and uncontrolled HT. All the groups received BT in the facilities of our university hospital at the same time every day (10:00-11:30 AM) for 10 min per day, 5 days per week, for a total duration of 15 days in a 3-week period. Systolic and diastolic blood pressures and pulse rates were measured before and after BT on daily basis. RESULTS: Overall, (1) the pulse rates of study groups measured after BT were significantly increased compared to before BT; (2) the systolic blood pressures of study groups measured before and after BT were found as comparable; and (3) the diastolic blood pressures of no HT and controlled HT groups measured before and after BT were not statistically significant (P > 0.05); however, in the uncontrolled HT group, the diastolic blood pressure showed a decreasing trend after BT (P < 0.05). CONCLUSIONS: In patients with OA, BT can be safely used without resulting in any meaningful changes in systolic and diastolic blood pressures in patients with normal and controlled HT but a decrease in diastolic blood pressure of patients with uncontrolled HT. This may be an advantage in OA patients having HT as comorbid disease.

Study of serum insulin levels in patients of euglycemic essential hypertension: a cross sectional study in North Indian population.

OBJECTIVE: Essential hypertension is associated with multiple metabolic abnormalities, among them one of the most important is hyperinsulinemia. Hyperinsulinemia has been suggested as being responsible for the increased arterial pressure in patients with essential hypertension. But this is contradicted by the finding that all patients of essential hypertension are not hyperinsulinemic. The present study was conducted to explore the hypothesis that hyperinsulinemia plays a pathogenic role in hypertension in euglycemic North Indian population. METHODS AND MATERIALS: 120 subjects were studied (60 hypertensive and 60 normotensive). Blood pressure, fasting insulin levels, lipid profile and BMI were calculated for both the groups. Statistical analysis was done using online statistical software freely at www.openepi.com. RESULTS: Hypertensive subjects were characterized by increased fasting insulin levels (16.77±7.62 vs. 8.84±2.04µIU/ml, p<0.01), increased BMI (p<0.01) and dyslipidemia, i.e. increased total cholesterol, high serum triglycerides, high LDL-C and low HDL-C with p<0.01. There was a positive correlation of fasting insulin levels with BMI, total cholesterol and LDL-C (p<0.01) and a negative correlation with HDL-C (p<0.05). However, serum insulin levels showed a non significant correlation with mean systolic and mean diastolic blood pressure (p>0.05). CONCLUSIONS: Our study showed a significant increase in serum insulin levels in hypertensive patients thereby supporting a possible pathogenic role of insulin resistance in onset of hypertension even when the fasting blood sugar is within normal limits.
