Influence of Bleeding Risk on Outcomes of Radial and Femoral Access for Percutaneous Coronary Intervention: An Analysis From the GLOBAL LEADERS Trial

BackgroundRadial artery access has been shown to reduce mortality and bleeding events, especially in patients with acute coronary syndromes. Despite this, interventional cardiologists experienced in femoral artery access still prefer that route for percutaneous coronary intervention. Little is known regarding the merits of each vascular access in patients stratified by their risk of bleeding.MethodsPatients from the Global Leaders trial were dichotomized into low or high risk of bleeding by the median of the PRECISE-DAPT score. Clinical outcomes were compared at 30 days.ResultsIn the overall population, there were no statistical differences between radial and femoral access in the rate of the primary end point, a composite of all-cause mortality, or new Q-wave myocardial infarction (MI) (hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.42-1.15). Radial access was associated with a significantly lower rate of the secondary safety end point, Bleeding Academic Research Consortium (BARC) 3 or 5 bleeding (HR 0.55, 95% CI 0.36-0.84). Compared by bleeding risk strata, in the high bleeding score population, the primary (HR 0.47, 95% CI 0.26-0.85; P = 0.012; P_interaction = 0.019) and secondary safety (HR 0.57, 95% CI 0.35-0.95; P = 0.030; P_interaction = 0.631) end points favoured radial access. In the low bleeding score population, however, the differences in the primary and secondary safety end points between radial and femoral artery access were no longer statistically significant.ConclusionsOur findings suggest that the outcomes of mortality or new Q-wave MI and BARC 3 or 5 bleeding favour radial access in patients with a high, but not those with a low, risk of bleeding. Because this was not a primary analysis, it should be considered hypothesis generating.     

Fractional Flow Reserve Derived From Computed Tomographic Angiography in Patients With Multivessel CAD

Background

The functional SYNTAX score (FSS) has been shown to improve the discrimination for major adverse cardiac events compared with the anatomic SYNTAX score (SS) while reducing interobserver variability. However, evidence supporting the noninvasive FSS in patients with multivessel coronary artery disease (CAD) is scarce.

Compliance with hormone replacement therapy at Songklanagarind Hospital

AIM: To determine compliance with hormone replacement therapy (HRT) over a 2-year period, reasons for discontinuing HRT and the factors associated with non-compliance. METHODS: A total of 202 women attending the menopause clinic at Songklanagarind Hospital and taking HRT were included in this retrospective study. Compliance was assessed for each 6-month interval within the first 2 years. Reasons for discontinuation were requested from women who had stopped using HRT. RESULTS: Compliance rates with HRT for the study group were 57.9% at 6 months, 42.6% at 12 months, 35.1% at 18 months and 32.7% at 24 months. The main reasons for discontinuing HRT were improvement of climacteric symptoms (20.9%), fear of cancer (16.4%) and irregular bleeding (11.9%). Logistic regression analysis revealed a significant increase in the risk of non-compliance of HRT among agriculturists or untrained workers (OR 4.7, 95% CI 1.2-18.8; reference, government employees), those with delayed onset of treatment (>1 years; OR 3.0, 95% CI 1.1-8.0; reference, 0-3 months) and those prescribed HRT for climacteric symptoms or reasons other than oophorectomy or ovarian failure (OR 18.2-41.6 depending on reasons). Agriculturists or untrained workers who delayed onset of treatment for climacteric symptoms had the highest expected non-compliance rate of 0.95%. CONCLUSION: Long-term compliance of HRT was not good at Songklanagarind menopause clinic. More attention has to be paid to the counseling of patients about HRT. Agricultural or untrained workers, late starting HRT, and presence of climacteric complaints were the significant factors for poor HRT compliance.     

Situation analysis of atypical squamous cells of undetermined significance smears in Songklanagarind Hospital

OBJECTIVE: To review the incidence, management, follow-up rate and colposcopic diagnosis of atypical squamous cells of undetermined significance (ASCUS) detected on cervical smears in Songklanagarind Hospital, Thailand. METHODS: A retrospective study of ASCUS smears taken during January 2000 to March 2001 at Songklanagarind Hospital was performed. The type of management was classified and the follow-up rate was detected. Cases with colposcopy, tissue biopsy, endocervical curettage, conization and hysterectomy specimen were reviewed. In the cases without tissue biopsy, the final diagnoses were based on the colposcopic examination. RESULTS: Among the 25068 Pap smears examined, the incidence of ASCUS was 0.62%. Of these, only 56.13% received the further evaluation. The non-compliance rate was 18.71%. The incidences of cervical intraepithelial neoplasia (CIN) and invasive cancer among the cases who received colposcopy were 15.96% and 2.13%, respectively. The incidence of CIN or invasive cancer in ASCUS favor reactive and ASCUS favor neoplasia were not different statistically significant. CONCLUSIONS: Management of ASCUS smears by follow-up may be inappropriate. A practice guideline which consists of active management, intensive follow-up system and well-organized data management should be used to improve the situation.     

Clinical Implication of Quantitative Flow Ratio After Percutaneous Coronary Intervention for 3-Vessel Disease

ObjectivesThe aim of this study was to investigate the impact of post–percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) on clinical outcomes in patients with de novo 3-vessel disease (3VD) treated with contemporary PCI.BackgroundThe clinical impact of post-PCI QFR in patients treated with state-of-the-art PCI for de novo 3VD is undetermined.MethodsAll vessels treated in the SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) II trial were retrospectively screened and analyzed for post-PCI QFR. The primary endpoint of this substudy was vessel-oriented composite endpoint (VOCE) at 2 years, defined as the composite of vessel-related cardiac death, vessel-related myocardial infarction, and target vessel revascularization. The receiver-operating characteristic curve was used to calculate the optimal cutoff value of post-PCI QFR for predicting 2-year VOCE. All the analyzable vessels were stratified on the basis of the optimal cutoff value.ResultsA total of 968 vessels treated with PCI were screened. Post-PCI QFR was analyzable in 771 (79.6%) vessels. A total of 52 (6.7%) VOCEs occurred at 2 years. The mean value of post-PCI QFR was 0.91 ± 0.07. The diagnostic performance of post-PCI QFR to predict 2-year VOCE was moderate (area under the curve: 0.702; 95% confidence interval: 0.633 to 0.772), with the optimal cutoff value of post-PCI QFR for predicting 2-year VOCE 0.91 (sensitivity 0.652, specificity 0.635). The incidence of 2-year VOCE in the vessels with post-PCI QFR <0.91 (n = 284) was significantly higher compared with vessels with post-PCI QFR ≥0.91 (n = 487) (12.0% vs. 3.7%; hazard ratio: 3.37; 95% confidence interval: 1.91 to 5.97; p < 0.001).ConclusionsA higher post-PCI QFR value is associated with improved vessel-related clinical outcomes in state-of-the art PCI practice for de novo 3VD. Achieving a post-PCI QFR value ≥0.91 in all treated vessels should be a target when treating de novo 3VD. These findings require confirmation in future prospective trials.     

Screening for genital human papillomavirus: results from an international validation study on human papillomavirus sampling techniques.

The objective of this study was to determine the validity of human papillomavirus (HPV) detection using exfoliated cervical cells compared with cervical biopsy specimens in women with normal cervix and to assess whether HPV detection rates using exfoliated cells is dependent on the number and order in which cervical scrapes are taken. Women undergoing hysterectomy for reasons other than cervical cancer were recruited in three hospitals in countries with varying risks of cervical cancer. After informed consent and at the time of surgery, three consecutive cervical scrapes were taken as well as four biopsy specimens, one in each of the quadrants around the cervical os. In this study, 331 women were recruited and provided 992 cell samples and 1324 biopsy samples. All scrapes and a sample of biopsy specimens (n = 103) were tested by polymerase chain reaction enzyme immunoassay using a general primer (GP5+/ bio6+). Type-specific tests were performed for 14 HPV types at the subpicogram level in one test and individually. Positive samples were verified using Southern blot hybridization. The prevalence of HPV DNA was 6.3% in cervical cells. Of 19 HPV positive samples in the scrapes, 17 were confirmed in the biopsy specimens. The agreement, as measured by the Kappa statistic, was 0.90 (P < 0.0001). The concordance in detecting HPV infection between scrapes and biopsy specimens was 97.5%, and the concordance in categorizing the samples as negatives was 94.4%. These values were unchanged when the order in which scrapes were taken was compared. Among women without cervical cancer, HPV DNA detection rates do not vary if exfoliated cells or random biopsy specimens are taken as the primary testing specimen. Screening programs based on highly sensitive HPV DNA detection technology in cell scrapes should expect a minimal underdetection.     

Diagnostic evaluation of Karman endometrial aspiration in patients with abnormal uterine bleeding

AIM: To assess sensitivity and specificity of Karman aspiration in the diagnosis of abnormal endometrium compared with the final diagnosis and evaluate tissue adequacy obtained by Karman aspiration. METHODS: The study group were women who presented with abnormal uterine bleeding to Songklanagarind Hospital between August 2003 and July 2004 and who underwent Karman aspiration prior to conventional curettage. The final diagnosis was defined as the most severe histopathology from either Karman aspiration or conventional curettage. Abnormal endometrium included inflammation, polyp, hyperplasia and malignant changes. RESULTS: Two hundred and twenty-six women were assessed. Endometrial aspiration showed a sensitivity of 89.6% and specificity 100.0% in diagnosis of abnormal endometrium. Abnormal endometrium was detected in 58 women. Of 11 women diagnosed with endometrial cancer, only one case was undetected by Karman aspiration due to a failure to create negative pressure in the uterus. Endometrial aspiration yielded adequate tissue in 86.7%. CONCLUSION: Karman endometrial aspiration is an accurate and easy procedure, and should be considered in the initial evaluation of abnormal uterine bleeding.
