Assessment of inter-rater agreement between physicians and their patients regarding medication adherence in a clinical questionnaire study.

While it is important to treat lifestyle-related diseases for the primary and secondary prevention of cardiovascular diseases, medication adherence is still poor. Although various causes of poor adherence have been reported, the differences between physicians and their patients regarding the recognition of medication adherence have not been well-investigated.We administered a questionnaire about medication adherence to 300 outpatients and their 23 cardiologists at the Department of Cardiology, Fukuoka University Hospital. The questionnaires for patients and physicians included acceptable total number of drug doses and dosing schedule, forgetting to take the medicine, and dose-reduction or -increase based on self-judgement. The patients were 70.6 ±â€Š12.3 years old and 61.0% (n = 183) were male. Patients reported that it was acceptable to receive 0-5 doses twice daily. The patients were divided into two groups: an agreement group, in which physicians and their patients had the same answer to the question regarding forgetting medication (203 cases; 67.7%), and a disagreement group (97 cases; 32.3%). Overall, the inter-rater agreement between physicians and patients with regard to forgetting medication was significant, but slight (κ coefficient = 0.12). In a multivariate analysis, absence of hypertension [odds ratio (OR): 0.21, 95% confidence interval (CI): 0.09-0.50, P < .001), ß-blocker usage (OR: 1.86, 95% CI: 1.11-3.12, P = .02), and biguanide usage (OR: 4.04, 95% CI: 1.43-11.41, P = .01) were independent predictors of disagreement with regard to forgetting medication.The inter-rater agreement between physicians and patients with regard to medication adherence was slight. An increase in inter-rater agreement should improve medication adherence.

A Case of Multifaceted Assessment in an Elderly Patient With Acute Decompensated Heart Failure.

Heart failure (HF) is a common health problem worldwide, including in Japan. Unfortunately, patient outcomes remain poor, with a 5-year survival rate of approximately 50%. Therefore, we need to assess the precise conditions, including cardiac function, in patients with HF, particularly in the elderly. We performed a multifaceted assessment in an elderly patient with HF on admission and at discharge using eight different evaluations (the mean life expectancy using the Seattle Heart Failure Model (SHFM), the severity of dementia, nutrition, medication adherence, biomarker (the level of brain natriuretic peptide in blood), sociality, performance and comorbidity). Each parameter was scored on a 5-point scale (excellent = 5 points; good = 4 points; fair (average) = 3 points; poor = 2 points; failure = 1 point; maximum total points of 40) (Fukuoka University Heart Failure Scoring System, FUFS). An 86-year-old male patient who complained of dyspnea and lower-leg edema was admitted to our university hospital due to acute decompensated HF. After treatment, his symptoms improved, as did his cardiothoracic ratio, plural effusion and pulmonary congestion, and he exhibited compensated HF. His total score improved from 28 to 32 points, and his mean life expectancy using SHFM increased from 4.9 to 5.4 years. We evaluated the precise conditions using a multifaceted assessment strategy in an elderly patient with HF. The strategy was useful for evaluate the patient's condition in this case.

Assessment of various parameters using simple non-invasive tests in patients with cardiovascular diseases with or without cardiac rehabilitation.

Cardiac rehabilitation (CR) improves cardiac function and exercise capacity in patients with cardiovascular disease (CVD). Simpler techniques are needed for use by physicians in the examination room to assess the usefulness of CR. We enrolled 46 consecutive CVD patients in a CR program (CR group) and prospectively followed them for 3 months. We compared them to 18 age-, gender- and body mass index-matched CVD patients without CR (non-CR group). Various parameters were measured at baseline and after 3 months using 3 simple non-invasive tests: severity of atherosclerosis [arterial velocity pulse index and arterial pressure volume index (API)] were determined using PASESA®, an autonomic nerve total activity amount index and a coefficient of variation of the R-R interval (CVRR) were determined using eHEART®, and peripheral resistance index, pressure rate product, stroke volume and cardiac index were determined using nico®]. There were no significant differences in patient characteristics including percentages (%) of ischemic heart disease and heart failure between the non-CR and CR groups. Systolic blood pressure (SBP), diastolic BP, heart rate and API at baseline significantly decreased and CVRR at baseline significantly increased after 3 months in the CR group, but not in the non-CR group. In addition, ΔAPI (Δ = the value after 3 months minus the value at baseline) was positively associated with ΔSBP in the CR group. In conclusion, CR significantly decreased BP and improved atherosclerosis and sympathetic nerve activity. These findings suggest that simple non-invasive tests may be useful for assessing the effects of CR.

[Assessment of risk factors for adverse events due to pemetrexed in patients with reduced renal function].

Pemetrexedis a key drug in the first and second -line therapy for non-small-cell lung cancer. It exhibits an increased area under the plasma drug concentration-time curve, and it has a prolonged half -life when administered to patients with reduced renal function, resulting in a high frequency of neutropenia. Accordingly, pemetrexed is administered to these patients with caution. Herein, we retrospectively investigated the background characteristics of patients with a creatinine clearance rate (Ccr) of<45 mL/min, who experienced severe adverse events due to pemetrexed. Thirty-eight patients with a Ccr of <45 mL/min were administered pemetrexed. Of these patients, 13 (34%) developed severe adverse events (≥Grade 3) such as neutropenia, thrombocytopenia, and nausea. Multiple logistic regression analysis revealed that a Ccr of <30 mL/min (p= 0.033) and the concomitant use of non-steroidal anti-inflammatory drugs (p=0.012) were significant risk factors for adverse events. Therefore, whenever possible, pemetrexed administration should be avoided in patients with a Ccr of <30 mL/ min and in those receiving concomitant non-steroidal anti-inflammatory drugs.

Assessment of inverse agonism for the angiotensin II type 1 receptor.

The angiotensin II (AngII) type 1 (AT1) receptor is a seven-transmembrane G-protein-coupled receptor that plays a regulatory role in the physiological and pathological processes of the cardiovascular system. AT1 receptor inherently shows constitutive activity even in the absence of AngII, and it is activated not only by AngII but also by AngII-independent mechanisms. Especially, mechanical stress induces cardiac hypertrophy through activation of AT1 receptor without the involvement of AngII. These AngII-independent activities of AT1 receptor can be inhibited by inverse agonists, but not by neutral antagonists. In this chapter, we describe the methods used for biochemical assessment of inverse agonism of a ligand for AT1 receptor. Their applications will improve our understanding of receptor activation and inactivation at a molecular level, and contribute to the development of AT1 receptor blockers possessing superior therapeutic efficacy in cardiovascular diseases.

Efficacy of a multicomponent program (patient-centered assessment and counseling for exercise plus nutrition [PACE+ Japan]) for lifestyle modification in patients with essential hypertension.

With conventional lifestyle modification programs, it can be difficult for hypertensive individuals to modify their lifestyles and maintain the changes. We assessed whether a multicomponent program (patient-centered assessment and counseling for exercise plus nutrition [PACE+ Japan]) based on behavior theory and social cognitive theory would be effective for treating patients with essential hypertension. We examined 57 outpatients aged 62+/-10 years with essential hypertension irrespective of antihypertensive drug treatment. Participants were randomly divided into two groups: 1) a PACE+ Japan follow-up group (n =18), who were given an action-plan sheet and systemic health counseling by a physician and counselor every 4 weeks for 24 weeks, and 2) a PACE+ Japan-only group (n =20), who were given an action-plan sheet but did not receive counseling. An age- and sex-matched control group (n =19) was also selected. The decrease in systolic blood pressure (SBP) (Delta SBP=SBP at 24 weeks minus that at 0 weeks) in the PACE+ Japan follow-up group was significantly greater than that in the control group. In addition, the Delta percentage of Fat (%Fat) and Delta urinary sodium extraction (U-Na) in the PACE+ Japan follow-up group were significantly greater than those in the control group. With regard to changes in total energy expenditure, exercise energy expenditure and total energy intake between 0 weeks and 24 weeks, significant improvements were observed for the PACE+ Japan follow-up group. Delta U-Na was determined to significantly predict Delta SBP as assessed by stepwise selection. In addition, the partial correlation coefficient of Delta SBP with Delta U-Na was 0.361 (p =0.011) as assessed by a multiple regression analysis. Therefore, PACE+ Japan follow-up counseling was associated with a reduction in SBP, which in turn was associated with reduction in U-Na. This new program may be effective for reducing blood pressure in hypertensives.
