Subjective Evaluation of Denture Adhesives: A Multicenter Randomized Controlled Trial

INTRODUCTION

Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined the effects of denture adhesives.

OBJECTIVE

This 10-center randomized controlled trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate the effects of short-term use of cream and powder denture adhesives.

METHODS

Patients were allocated into 2 cream- and powder-type adhesive groups and 1 control group. Intervention groups were treated with the 2 adhesives (1 each), and the control group received saline solution. Adhesive or control was applied to the denture-mucosal surface for 4 d, and data at baseline and after day 4 of intervention (i.e., 8 meals) were obtained. Patient satisfaction was evaluated with a 100-mm visual analog scale. Oral health-related quality of life was measured with the Japanese version of the Oral Health Impact Profile for Edentulous Patients. Perceived chewing ability was evaluated by a questionnaire regarding ease of chewing and swallowing food. Between-group comparisons were performed with Kruskal-Wallis tests with the Mann-Whitney U test adjusted by Bonferroni correction. Within-group comparisons of pre- and postintervention measurements were performed with the Wilcoxon signed-rank test. Intention-to-treat analysis was also performed.

RESULTS

Between-group comparisons showed no significant differences for general satisfaction or Oral Health Impact Profile for Edentulous Patients. However, significant differences in satisfaction with various denture functions with cream- and powder-type adhesives were seen in pre- and postintervention comparisons (P < 0.05). Significant differences were also observed for perceived chewing ability of hard foods (P < 0.05).

CONCLUSION

These results suggest that although denture adhesives do not invariably improve denture function, they do affect subjective evaluations and possibly chewing of hard foods. Therefore, the effects of denture adhesive use are insufficient to resolve any fundamental dissatisfaction with dentures ( ClinicalTrials.gov NCT01712802 ).

KNOWLEDGE TRANSFER STATEMENT

The results of this study suggest that denture adhesives should be applied under certain conditions; however, an appropriate diagnosis is important before application. These practice-based data provide information to establish evidence-based guidelines for applying denture adhesives.

Prognostic Value of Neurological Status on Hospital Arrival for Short-Term Outcome in Patients With Cardiovascular Shock - Sub-analysis of the Japanese Circulation Society Cardiovascular Shock Registry

BACKGROUND

Consciousness disturbance is one of the major clinical signs associated with shock state, but its prognostic value has not been previously evaluated in cardiovascular shock patients. We aimed to evaluate the prognostic value of neurological status for 30-day mortality in cardiovascular shock patients without out-of-hospital cardiac arrest (OHCA). Methods and Results: Patients with out-of-hospital onset cardiovascular shock were recruited from the Japanese Circulation Society Shock Registry. Neurological status upon hospital arrival was evaluated using the Japan Coma Scale (JCS). Patients were divided into 4 groups according to the JCS: alert, JCS 0; awake, JCS 1-3 (not fully alert but awake without any stimuli); arousable, JCS 10-30 (arousable with stimulation); and coma JCS 100-300 (unarousable). The primary endpoint was 30-day all-cause death. In total, 700 cardiovascular shock patients without OHCA were assessed. The coma group was associated with a higher incidence of 30-day all-cause death compared with other groups (alert, 15.3%; awake, 24.4%; arousable, 36.8%; coma, 48.5%, P<0.001). Similar trends were observed in etiologically divergent subgroups (acute coronary syndrome, non-ischemic arrhythmia, and aortic disease). On multivariate Cox regression analysis, arousable (hazard ratio [HR], 1.82; 95% CI: 1.16-2.85, P=0.009) and coma (HR, 2.72; 95% CI: 1.76-4.22, P<0.001) (reference: alert) independently predicted 30-day mortality.

CONCLUSIONS

Neurological status upon hospital arrival was useful to predict 30-day mortality in cardiovascular shock patients without OHCA.

Clinical characteristics and prognostic factors in acute coronary syndrome patients complicated with cardiogenic shock in Japan: analysis from the Japanese Circulation Society Cardiovascular Shock Registry

Cardiogenic shock frequently leads to death even with intensive treatment. Although the leading cause of cardiogenic shock is acute coronary syndrome (ACS), the clinical characteristics and the prognosis of ACS with cardiogenic shock in the present era still remain to be elucidated. We analyzed clinical characteristics and predictors of 30-day mortality in ACS with cardiogenic shock in Japan. The Japanese Circulation Society Cardiovascular Shock registry was a prospective, observational, multicenter, cohort study. Between May 2012 and June 2014, 495 ACS patients with cardiogenic shock were analyzed. The primary endpoint was 30-day all-cause mortality. The median [interquartile range; IQR] age was 71.0 [63.0, 80.0] years. The median [IQR] value of systolic blood pressure (SBP) and heart rate were 75.0 [50.0, 86.5] mm Hg and 65.0 [38.0, 98.0] bpm, respectively. Multivariable analysis showed an odds ratio (OR) of 4.76 (confidence intervals; CI 1.97-11.5, p < 0.001) in the lowest SBP category (< 50 mm Hg) for SBP ≥ 90 mm Hg. Moreover, age per 10 years increase (OR 1.38, CI 1.18-1.61, p = 0.002), deep coma (OR 3.49, CI 1.94-6.34, p < 0.001), congestive heart failure (OR 3.81, CI 2.04-7.59, p < 0.001) and left main trunk disease (LMTD) (OR 2.81, CI 1.55-5.10, p < 0.001) were independent predictors. Severe hypotension, older age, deep coma, congestive heart failure, and LMTD were independent unfavorable factors in ACS complicated by cardiogenic shock in Japan. A prompt assessment of high-risk patients referring to those predictors in emergency room could lead to appropriate treatment without delay.

Differences in Initial Electrocardiographic Findings of Apical Takotsubo Syndrome According to the Time from Symptom Onset

No previous study has examined the differences in patient characteristics and initial electrocardiographic findings of Takotsubo syndrome (TTS) according to the time from onset to electrocardiography. Using the Tokyo Cardiovascular Care Unit network registry 2011-2012, we retrospectively identified 106 apical TTS patients in whom symptom onset time was specified, and classified the patients into 5 groups according to the time from onset to the initial electrocardiography: <3 hours (n = 45), 3 to 6 hours (n = 20), 6 to 12 hours (n = 12), 12 to 24 hours (n = 13), and ≥24 hours (n = 16). There was no significant difference across the groups in age, gender, symptoms, triggers, vital signs, blood tests, or in-hospital outcomes. In the electrocardiographic findings, ST-elevation was more frequent in leads V2-V4 than in the other leads, especially in the <24 hour groups, but did not differ significantly across groups. T-wave inversion was more frequent in leads V3-V6, especially in the ≥24 hour group, and differed significantly across groups. The total number of leads with T-wave inversion was significantly larger in the ≥24 hour group than in the <24 hour groups (mean, 5.9 leads vs 1.5 to 2.9 leads; p < 0.001). Isolated ST-elevation was the most frequent pattern of ST-T change in precordial leads (42% to 56%) in the <24 hour groups, while isolated T-wave inversion was the most frequent (44%) in the ≥24 hour group (p = 0.018). Neither ST-elevation nor T-wave inversion was observed in precordial leads in 10 (9%) patients. In conclusion, our results suggest that the initial electrocardiographic findings of apical TTS are affected by the time from onset to electrocardiography and display a wide variation in ST-T changes.

Renal Function and Outcome of Out-of-Hospital Cardiac Arrest - Multicenter Prospective Study (SOS-KANTO 2012 Study)

BACKGROUND

Renal dysfunction is associated with increased cardiovascular-related mortality, but its impact on outcome of out-of-hospital cardiac arrest (OHCA) remains unclear. We assessed whether post-OHCA outcome correlated with renal function early after OHCA. Methods and Results: Of the 16,452 registered patients in the SOS-KANTO 2012 Study, 5,112 cardiogenic OHCA adults with creatinine measurement (mean age, 72 years; male, 64%) were examined. First-obtained creatinine was used to assess eGFR. Associations between eGFR groups, ≥60 (n=997), 45-59 (n=1,311), 30-44 (n=1,441), and <30 mL/min/1.73 m²(n=1,363), and 3-month survival and neurological outcomes were examined. Favorable neurological outcome was defined as cerebral performance categories 1 or 2. Survival rate (15.1%, 9.7%, 3.9%, and 2.9%; P<0.001) and proportion of favorable neurological outcome (12.3%, 7.4%, 2.6%, and 2.2%; P<0.001) were determined for eGFR groups ≥60, 45-59, 30-44, and <30 mL/min/1.73 m², respectively. The survival rate decreased with eGFR (<60 mL/min/1.73 m²), and survival adjusted OR were 0.74 (95% CI: 0.54-1.03), 0.42 (95% CI: 0.28-0.62), and 0.43 (95% CI: 0.28-0.68) for eGFR 45-59, 30-44, and <30 mL/min/1.73 m², respectively. The adjusted OR for favorable neurological outcome also decreased with eGFR: 0.74 (95% CI: 0.52-1.06), 0.40 (95% CI: 0.25-0.64), and 0.48 (95% CI: 0.29-0.81), respectively.

CONCLUSIONS

An independent and graded association was observed between decreased eGFR and 3-month survival and proportion of favorable neurological outcome in cardiogenic OHCA patients.

Gender Differences Among Patients With Acute Pulmonary Embolism

Gender differences in patients with acute pulmonary embolism (APE) remain unclear and controversial. We aimed to understand the gender differences in patients with APE treated in the cardiovascular care units. The registry database of 1,428 patients with APE treated at the Tokyo cardiovascular care unit Network institutions from 2010 to 2014 was retrieved for analysis. In all, 795 women (55.7%) and 633 men (44.3%) were included in this study. The women were older than men (68.0 ± 16.1 vs 60.9 ± 15.6 years, p < 0.0001). Compared with men, women had more complaints of dyspnea and disturbed consciousness, lesser complaints of leg symptoms, and chest pain. Pulmonary arterial systolic pressure (51.5 ± 22.2 mm Hg vs 47.4 ± 22.4 mm Hg, p = 0.012) and the serum B-type natriuretic peptide level (180.4 [50.7 to 526.1] pg/ml vs 107.0 [25.0 to 306.8] pg/ml, p < 0.0001) on admission, was higher in women than in men. Severe cases with massive embolism were seen more in women compared with men (14.6% vs 9.2%, p = 0.0002). The use of inferior vena cava filters were lower in women than in men (31.9% vs 37.3%, p = 0.029). Furthermore, 30-day PE-related mortality was higher in women than in men significantly (5.0% vs 2.8%, p = 0.043). In conclusion, women APE patients were older with higher severity than men APE patients, resulting in poor prognosis.

Association of the time to first epinephrine administration and outcomes in out-of-hospital cardiac arrest: SOS-KANTO 2012 study

OBJECTIVE

This study assessed the association between the timing of first epinephrine administration (EA) and the neurological outcomes following out-of-hospital cardiac arrests (OHCAs) with both initial shockable and non-shockable rhythms.

METHODS

This was a post-hoc analysis of a multicenter prospective cohort study (SOS-KANTO 2012), which registered OHCA patients in the Kanto region of Japan from January 2012 to March 2013. We included consecutive adult OHCA patients who received epinephrine. The primary result included 1-month favorable neurological outcomes defined as cerebral performance category (CPC) 1 or 2. Secondary results included 1-month survival and return of spontaneous circulation (ROSC) after arrival at the hospital. Multivariable logistic regression analysis determined the association between delay per minute of the time from call to first EA in both pre- or in-hospital settings and outcomes.

RESULTS

Of the 16,452 patients, 9344 were eligible for our analyses. In univariable analysis, the delay in EA was associated with decreased favorable neurological outcomes only when the initial rhythm was a non-shockable rhythm. In multivariable analyses, delay in EA was associated with decreased ROSC (adjusted odds ratio [OR] for one minute delay, 0.97; 95% confidence interval [CI], 0.96-0.98) and 1-month survival (adjusted OR, 0.95; 95% CI, 0.92-0.97) when the initial rhythm was a non-shockable rhythm, whereas during a shockable rhythm, delay in EA was not associated with decreased ROSC and 1-month survival.

CONCLUSIONS

While assessing the effectiveness of epinephrine for OHCA, we should consider the time-limited effects of epinephrine. Additionally, consideration of early EA based on the pathophysiology is needed.

Clinical impact of thrombus aspiration on in-hospital mortality in each culprit lesion in the setting of ST-segment elevation myocardial infarction

Recent randomized clinical trials have questioned the clinical benefits of thrombus aspiration (TA) in ST-segment elevation myocardial infarction (STEMI). Real-world data on TA and the efficacy of TA for various culprit lesions have not been sufficiently evaluated. This study mainly aimed to evaluate whether the clinical impact of TA depends on culprit lesions in the setting of STEMI. We surveyed the Tokyo Coronary Care Unit Network Registry, a prospective cohort study, between 2010 and 2014, which included 10,232 patients with STEMI. In-hospital deaths occurred in 538 patients (5.3%). Improved Thrombolysis in Myocardial Infarction flow was more frequently observed in patients who underwent TA than in those who did not (87 vs. 80%; p < 0.001). Univariate logistic regression analysis revealed that TA was associated with a lower in-hospital mortality rate [odds ratio (OR), 0.80; 95% confidential interval (CI), 0.66-0.96; p = 0.016]. However, the difference was not significant after multivariate logistic regression analysis (OR 0.95; 95% CI 0.71-1.17; p = 0.355). Only TA for the left circumflex (LCx) lesions was associated with a better prognosis (OR 0.38; 95% CI 0.21-0.72; p = 0.003). The effect persisted after adjustment (OR 0.50; 95% CI 0.25-0.99; p = 0.049) but was attenuated after analysis using inverse probability weighting (OR 0.97; 95% CI 0.93-0.99; p = 0.048). On the basis of the findings in a large Japanese cohort, a prognostic benefit of TA on in-hospital mortality was not observed. The effect of TA on the LCx lesions was marginally significant and limited. Therefore, TA is not recommended in Japanese patients with STEMI.

Impact of smoking history on the association between Eicosapentaenoic acid to arachidonic acid ratio and acute coronary syndrome: A multicenter cross-sectional study

INTRODUCTION

The association among smoking history, eicosapentaenoic acid (EPA) to arachidonic acid (AA) ratio and acute coronary syndrome (ACS) is yet to be investigated. The present study aimed to clarify the association between the EPA/AA ratio and ACS prevalence in patients admitted to the cardiology department based on their smoking history.

METHODS

We enrolled 1733 patients from five cardiology divisions located in Tokyo, Japan, and measured their levels of polyunsaturated fatty acids, including EPA and AA, from January 2004 to May 2011. We assessed the association between the EPA/AA ratio and ACS in the subgroups stratified according to smoking history (never, former, current smokers) using multivariate logistic models.

RESULTS

A high EPA/AA ratio was significantly associated with decreased odds of ACS among patients without a smoking history (adjusted odds ratio AOR=0.20, 95% CI: 0.04–0.86) but not in patients with a smoking history (former smoker, AOR=1.50, 95% CI: 0.44–5.03; current smoker, AOR=3.73, 95% CI: 0.34–40.6).

CONCLUSIONS

The EPA/AA ratio and ACS occurrence were found to be significantly associated in patients without a smoking history; however, no such association existed in patients with a smoking history.
