RESUMO

The patient is a 76-year-old man. His chief complaint of chest pain led to a diagnosis of pericardial effusion of unknown cause, and pericardial drainage was performed. On the 30th day, chest pain appeared again. Echocardiography revealed a pericardial fluid reaccumulation and a substantial mass in the pericardial space. Surgical drainage was performed to find the cause. A hematoma/mass was present on the epicardium. The pericardial sac was filled with hematoma. The hematoma was removed, but part of the mass infiltrated close to the anterior descending branch of the left coronary artery, and removal of that part was abandoned. The intrapericardial hematoma and epicardium were submitted to pathology leading to the diagnosis of synovial sarcoma. The patient was discharged home 14 days after surgery.

RESUMO

PURPOSE: Several landmark trials have reported that direct oral anticoagulants (DOACs) are more effective in preventing stroke and systemic embolism than vitamin K antagonists. However, nonadherence to DOACs worsens prognosis in patients with nonvalvular atrial fibrillation (NVAF) despite the effectiveness of the drugs. The purpose of this study was to evaluate the effects of a pharmacist-led educational interventional program involving motivational interviewing on medication adherence, as assessed by electronic monitoring, in patients receiving DOACs for the treatment of NVAF. METHODS: This prospective, randomized, interventional study was conducted at outpatient cardiology clinics at general hospitals and pharmacies in Japan. Patients with NVAF who were treated with a once-daily DOAC (edoxaban) or a twice-daily DOAC (apixaban) were randomized to receive either: (1) an educational interventional program involving motivational interviewing regarding adherence to anticoagulants; or (2) standard medication counseling. The primary end point was the change in the medication adherence rate, calculated as the number of days that patients appropriately took the drug, as assessed by an electronic monitoring device, divided by the total number of days that the drug was prescribed, from a 12-week observation period to a 12-week intervention period. The secondary end points were tolerability outcomes. The effect of the educational interventional program on the primary end point was analyzed in subgroups stratified by gender and type of DOAC received. FINDINGS: A total of 268 patients completed the observation period and were randomly assigned to one of the two study groups. The difference in the primary end point between the educational interventional program group and the standard medication counseling group was not significant (mean [SD], 2.9% [7.5%] vs 3.4% [8.3%]). On multiple linear regression analysis, the difference in DOAC adherence between the two groups was not significant, but that adherence to apixaban was significantly improved among men in the educational interventional program (ß = 0.219; P = 0.012). Two patients died of causes considered unrelated to treatment; no stroke/systemic embolism or major bleeding events were observed. IMPLICATIONS: In this randomized, controlled study of the effects of a pharmacist-led educational interventional program using motivational interviewing on adherence to DOACs among patients with NVAF, adherence to DOACs, as assessed using an electronic monitoring device, was not improved with the educational interventional program compared to standard medication counseling . However, adherence to twice-daily apixaban was improved among men, but not among women, in the educational interventional program group. In this study, the selection of DOACs was not randomized, and the lack of assessment of the association between adherence to DOACs and clinical outcomes was a limitation.

RESUMO

BACKGROUND: Nonadherence diminishes the efficacy of direct oral anticoagulants (DOACs) in patients with nonvalvular atrial fibrillation (NVAF). This report presents the baseline survey results regarding medication adherence among NVAF patients who were treated with once-daily edoxaban or twice-daily apixaban from a randomized control trial of the effect of an educational intervention on DOAC adherence. METHODS: We prospectively studied 301 NVAF patients who were treated with edoxaban (n = 175) or apixaban (n = 126) during the 12-week observation period. Adherence was measured with an electronic monitoring system and is expressed as the percentage of days with the correct doses in the measurement period (days). Adherence to DOAC therapy was defined based on the standard threshold (≥80%) or a strict threshold (≥90%). RESULTS: Of the 301 patients, 33 had incomplete data or protocol deviations, leaving 268 patients (edoxaban 158 and apixaban 110) for the per-protocol baseline analysis. There was no difference in adherence (threshold ≥80%) between the groups (edoxaban 95% vs apixaban 91%, P = .2), but there was a lower proportion of patients with strict adherence (threshold ≥90%) among apixaban users than among edoxaban users (edoxaban 87% vs apixaban 76%, P = .02). Multivariate analysis showed a negative relationship between apixaban use and an adherence rate ≥90% (odds ratio 0.49, 95% confidence interval [CI]: 0.25-0.94). CONCLUSIONS: Our study showed that the proportion of DOAC users with adherence (≥80%) did not differ between the groups, but the proportion of patients with strict adherence (≥90%) was lower among those using apixaban than among those using edoxaban.

RESUMO

We report the case of a 33-year-old woman with no history of coronary risk factors or chest pain who experienced intermittent chest pain at rest for several minutes from 2 PM. At 8 AM the next day, chest pain recurred and persisted for about 1 hour. She was transported to our hospital by ambulance, where electrocardiogram showed ST-elevation in the precordial leads, and blood tests showed elevation of cardiac markers. She was diagnosed with ST-elevation myocardial infarction. Because she was a young woman without any risk factors, coronary spastic angina was suspected. Coronary angiography without intracoronary nitrate administration revealed diffuse 75% stenosis in the proximal right coronary artery (RCA) and diffuse 90% stenosis in the left anterior descending artery (LAD). A coronary spasm provocation test elicited chest pain; coronary angiography showed 99% diffuse stenosis of LAD; and electrocardiogram showed precordial ST-segment elevation. Although intracoronary nitroglycerin injection attenuated the coronary spasm in the RCA and proximal LAD, 90% stenosis and coronary dissection were observed in the midportion of the LAD. When the imaging test that was carried out before the provocation test was reexamined, the dissection was recognized, and there was no clear dissection progress after the test. Intravascular ultrasound showed dissection of the LAD, as did angiography. We treated the patient using medical therapy instead of percutaneous coronary intervention.The patient did not suffer any anginal attack and improved sufficiently to be discharged. She remained free of attacks for about 10 years to the present time, and follow-up is continuing.

RESUMO

Background This study aimed to examine the impact of baseline eicosapentaenoic acid (EPA) to arachidonic acid (AA) ratio on clinical outcomes of patients with acute coronary syndrome. Methods and Results In the HIJ-PROPER (Heart Institute of Japan Proper Level of Lipid Lowering With Pitavastatin and Ezetimibe in Acute Coronary Syndrome) study, 1734 patients with acute coronary syndrome and dyslipidemia were randomly assigned to pitavastatin+ezetimibe therapy or pitavastatin monotherapy. We divided the patients into 2 groups based on EPA/AA ratio on admission (cutoff 0.34 µg/mL as median of baseline EPA/AA ratio) and examined their clinical outcomes. The primary end point comprised all-cause death, nonfatal myocardial infarction, nonfatal stroke, unstable angina pectoris, or ischemia-driven revascularization. Percentage reduction of low-density lipoprotein cholesterol and triglyceride from baseline to follow-up was similar regardless of baseline EPA/AA ratio. Despite the mean low-density lipoprotein cholesterol level during follow-up being similar between the low- and high-EPA/AA groups, the mean triglyceride levels during follow-up were significantly higher in the low- than in the high-EPA/AA group. After 3 years of follow-up, the cumulative incidence of the primary end point in patients with low EPA/AA was 27.2% in the pitavastatin+ezetimibe group compared with 36.6% in the pitavastatin-monotherapy group (hazard ratio 0.69; 95% CI, 0.52-0.93; P=0.015). However, there was no effect of pitavastatin+ezetimibe therapy on the primary end point in patients with high EPA/AA (hazard ratio 0.92; 95% CI, 0.70-1.20; P=0.52). Conclusions Among acute coronary syndrome patients who have dyslipidemia and low EPA/AA ratio, adding ezetimibe to statin decreases the risk of cardiovascular events compared with statin monotherapy.

RESUMO

Polycystic kidney disease (PKD) is a multiple cystic disease involving both the kidneys. Some studies have reported cases of patients with PKD and concurrent aortic dissection; however, autopsy has been performed in only few of these cases. Here, we present the case of a 62-year-old male patient with PKD who showed generalized vascular degeneration, including aortic dissection. The patient had a family history of autosomal dominant PKD and was brought to our hospital because of cardiopulmonary arrest. He was diagnosed with Stanford type A aortic dissection and died on the same day, despite being under cardiopulmonary resuscitation. Autopsy detected multiple cysts in the kidneys, liver, pancreas, and testes. Moreover, multiple tears in the vascular wall of the splenic artery and superior mesenteric artery, including the aorta, were observed. The case findings indicate that patients with PKD may develop associated generalized vascular disease; however, development of cerebral aneurysms and aortic dissections with PKD is particularly serious. Therefore, suitable screening tests must be developed for the early diagnosis and disease characterization, thus, ensuring that the appropriate treatment is administered to the patients.

RESUMO

AIMS: There are regional differences in the patient characteristics, management, and outcomes of hospitalized patients with heart failure (HF). The aim of this study was to evaluate the clinical characteristics and outcomes of Japanese patients who are hospitalized with HF on the basis of the left ventricular ejection fraction (LVEF) stratum. METHODS AND RESULTS: We retrospectively conducted a multicentre cohort study of 1245 hospitalized patients with decompensated HF between 2013 and 2014. Of these patients, 36% had an LVEF < 40% [HF with reduced ejection fraction (HFrEF), median age 72 years, 71% male], 21% had an LVEF 40-49% [HF with mid-range EF (HFmrEF), 77 years, 56% male], and 43% had an LVEF ≥ 50% [HF with preserved EF (HFpEF), 81 years, 44% male]. The primary outcome was death from any cause, and the secondary outcomes were cardiac death and re-hospitalization due to worsened HF after hospital discharge. There were high proportions of non-ischaemic cardiomyopathy (32%) in HFrEF patients, coronary artery disease (44%) in HFmrEF patients, and valvular disease (39%) in HFpEF patients. The frequencies of intravenous diuretic and natriuretic peptide administration during hospitalization were 66% and 30%, respectively. The median hospital stay for the overall population was 19 days, and the length of stay was >7 days for >90% of patients. In-hospital mortality was 7%, but was not different among the LVEF groups (HFrEF 7%, HFmrEF 6%, and HFpEF 8%). After a median follow-up of 19 months (range, 3-26 months), 192 (17%) of the 1156 patients who were discharged alive died, and 534 (46%) were re-hospitalized after hospital discharge. There were no significant differences in mortality after hospital discharge among the three LVEF groups (HFrEF 18%, HFmrEF 16%, and HFpEF 16%). There were no differences in cardiac death or re-hospitalization due to worsened HF after hospital discharge among the LVEF groups (cardiac death: HFrEF 8%, HFmrEF 7%, and HFpEF 7%; re-hospitalization due to worsened HF: HFrEF 19%, HFmrEF 16%, and HFpEF 17%). Multivariable-adjusted analyses showed that the HFmrEF and HFrEF groups, compared with the HFpEF group, were not associated with an increased risk for in-hospital death or death after hospital discharge. Non-cardiac causes of death and re-hospitalization after hospital discharge accounted for 35% and 38%, respectively. CONCLUSIONS: Our results revealed different clinical characteristics but similar mortality rates in the HFrEF, HFmrEF, and HFpEF groups. The most common cause of death and re-hospitalization after hospital discharge was HF, but non-cardiac causes also contributed to their prognosis. Integrated management approaches will be required for HF patients.

RESUMO

OBJECTIVES: Cesarean section is associated with an increased risk for venous thromboembolism (VTE). The safety and efficacy of primary prophylaxis of fondaparinux, a synthetic sulfated pentasaccharide heparin analog, in women at risk after cesarean section is uncertain. METHODS: This was a retrospective study of 295 cases of pregnant women presenting to a tertiary referral center of Nara, Japan, to evaluate the usefulness of thromboprophylaxis with fondaparinux after cesarean delivery between 2011 and 2012. Patients were initially received unfractionated heparin (once 5,000 IU subcutaneously, twice a day), starting 6 hours after cesarean section for 24 hours, and then treated with fondaparinux (once 2.5 mg daily, subcutaneously) for 5 days. The primary efficacy end-point was an improvement in the incidence of symptomatic VTE or fatal post-cesarean pulmonary thromboembolism. The primary safety end-point was major bleeding during treatment. RESULTS: There were neither any episodes of symptomatic VTE cases nor maternal deaths. A total of 10 patients had a bleeding event. Major bleeding complication was observed in 2 (0.68%) of 295 patients receiving fondaparinux. Non-major bleeding into critical sites was observed in 8 patients, often at surgical sites, and recovery was not delayed. CONCLUSION: This study demonstrates the safety and efficacy of fondaparinux in women at high risk of VTE after cesarean section. Large phase trials comparing clinical outcomes with fondaparinux across a wide spectrum of patients are needed to confirm these observations.

RESUMO

A 34-year-old primigravida who had undergone thrombectomy for deep venous thrombosis (DVT) in her leg and exhibited low protein S activity, indicating predisposition to thrombosis, developed DVT of the leg. No pulmonary embolism was detected. After anticoagulant therapy with unfractionated heparin was discontinued because of liver dysfunction, danaparoid treatment was administered in hospital. The patient had a normal delivery after 39 weeks' gestation with no recurrence of thrombosis. During her second pregnancy four years later, she gave herself fondaparinux injections. She delivered normally after 38 weeks' gestation without experiencing DVT. Fondaparinux may be a useful anticoagulant for heparin-intolerant pregnant women.

RESUMO

OBJECTIVE: To evaluate a sequential screening method's efficacy in predicting symptomatic pulmonary thromboembolism (PTE) after gynecologic surgery. METHODS: A prospective study employing a two-stage screening process was conducted among consecutive asymptomatic adults who underwent outpatient evaluation for gynecologic surgery at Nara Medical University Hospital, Japan, between April 1, 2004, and December 31, 2013. Patients with a preoperative plasma D-dimer level greater than or equal to 1.0µg/mL underwent compression ultrasonography of the lower extremities. The primary outcome measure was postoperative detection of symptomatic PTE. RESULTS: Overall, 1729 patients were included. The mean D-dimer level was 1.7±3.3µg/mL. Compression ultrasonography was conducted among 470 (27.1%) patients with positive D-dimer test results; symptomatic deep vein thrombosis (DVT) was preoperatively detected among 94 (20.0%) of them. Patients with DVT (n=94) had higher D-dimer levels than patients (n=1635) without (7.8±12.8µg/mL vs 1.1±1.8µg/mL; P<0.001). Despite anticoagulant therapy, symptomatic PTE was detected postoperatively among two of these 94 patients. Symptomatic PTE was also detected among four of 376 patients with positive D-dimer test results but no evidence of DVT by ultrasonography. No clinical onset of postoperative PTE was observed among 1259 patients with D-dimer levels below the cut-off value. CONCLUSION: The PROVEN screening strategy (Preoperative surveillance using a sequential strategy) was ineffective at predicting postoperative symptomatic PTE.

RESUMO

BACKGROUND: The effects of the combination of angiotensin II receptor blocker (ARB) plus dihydropyridine calcium channel blockers (DHP-CCBs), which is known as a potent antihypertensive drug regimen, on cardiovascular events remain unclear. OBJECTIVE: The purpose of this post hoc subgroup analysis was to compare the incidence of major adverse cardiovascular events (MACE) of patients treated with candesartan and amlodipine with that of those with candesartan and non-amlodipine CCBs in hypertensive patients with coronary artery disease (CAD). METHODS: HIJ-CREATE was a multicenter, prospective, randomized, controlled study that compared the effects of candesartan-based with those of non-ARB-based standard therapy on MACE in 2049 hypertensive patients with CAD. In the candesartan group, a total of 335 patients were treated with DHP-CCBs (amlodipine: 170 and non-amlodipine-CCBs: 165) at the baseline. In this sub-analysis, we compared, among the participants allocated to candesartan regimen, the long-term effects of amlodipine and non-amlodipine CCBs that were concomitantly given with ARB, although the choice of CCB was not randomized. RESULTS: The median follow-up was 3.9 years. Treatment using amlodipine with candesartan reduced the risk of MACE by 38% (hazard ratio, 0.62; 95% confidence interval, 0.41-0.94, p=0.025), as compared to patients treated with non-amlodipine-CCBs and candesartan. In a multivariate analysis, combination therapy of candesartan with amlodipine was an independent predictor of reduced risk of MACE. CONCLUSIONS: The results suggest that the combination of amlodipine and candesartan is more beneficial in reducing MACE in hypertensive patients with CAD compared to non-amlodipine-DHP-CCBs in combination therapy with candesartan. Further investigation in larger-scale prospective randomized studies is required to reach any conclusion as to the superiority of combination therapy of candesartan with amlodipine.

RESUMO

BACKGROUND: The purpose of this study was to compare the long-term survival of patients with stage IIIB squamous cell carcinoma of the cervix treated with neoadjuvant intraarterial chemotherapy (IA-NAC) versus those treated with concurrent chemoradiotherapy (CCRT). METHODS: We retrospectively reviewed the clinical records of 38 patients with stage IIIB squamous cell carcinoma of the cervix admitted between January 1994 and December 1999 who received IA-NAC followed by abdominal radical hysterectomy (ARH) or radiotherapy (RT). IA-NAC consisted of bilateral infusion via the internal iliac artery of cisplatin, bleomycin and pirarubicin for 2-3 courses. A historical control group of 64 patients who underwent primary CCRT from January 2000 to September 2007 was used for comparison. RESULTS: In the IA-NAC group, 12 patients (31.6%) with operable tumors underwent ARH, and the remaining 26 patients (68.4%) received RT. The response rates were 86.8% (12 complete response + 21 partial response) for IA-NAC and 98.4% (26 complete response + 37 partial response) for CCRT (P = 0.077), respectively. The 5-year overall survival and disease-free survival rates were 62.4 and 44.5% for IA-NAC and 51.1 and 46.9% for CCRT (P = 0.247 and 0.776), respectively. The 5-year overall survival and disease-free survival rates were 75.0 and 58.3% for the patients receiving IA-NAC followed by ARH, and 55.3 and 37.6% for the patients receiving IA-NAC followed by RT (P = 0.368 and 0.262), respectively. CONCLUSIONS: In the present study, IA-NAC followed by ARH or RT and primary CCRT showed similar survival rates for stage IIIB squamous cell carcinoma of the cervix.

RESUMO

Two histologic types, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC), are the common histology in ovarian cancer patients who have associated endometriosis. However, both tumor types have distinct clinicopathological characteristics and molecular phenotypes. EAC is predominantly positive for estrogen receptor (ER), but CCC specifically exhibits lower ER expression. This study reviews the current understanding of the role of the ER information in the pathogenesis of CCC, as well as the English language literature for biochemical studies on ER expression and estrogenic action in CCC. The iron-mediated oxidative stress occurs due to repeated hemorrhage in endometriosis, then this compound oxidatively modifies genomic DNA and, subsequently, ER depletion may be observed. There are a number of factors that interfere with ER expression and estrogen activity, which include DNA methylation of the promoter region, histone deacetylation, heme and iron binding, chromatin remodeling and ubiquitin ligase activity. Loss of estrogen function may be a turning point in CCC progression and aggressiveness.

RESUMO

Inflammation plays a role in the pathogenesis of endometriosis. Endometriosis-associated ovarian carcinogenesis might be promoted through oxidative stress-induced increased genomic instability, aberrant methylation, and aberrant chromatin remodeling, as well as mutations of tumor suppressor genes. Aberrant expression of ARID1A, PIK3CA, and NF-kB genes has been recognized as the major target genes involved in oxidative stress-induced carcinogenesis. HNF-1beta appears to play a key role in anti-oxidative defense mechanisms. We discuss the pathophysiologic roles of oxidative stress as somatic mutations as well as highly specific agents that effectively modulate these targets.

RESUMO

PROBLEM: Preeclampsia, a pregnancy-related hypertensive disorder, is one of the leading causes of fetal and maternal death globally. Angiogenic factors including vascular endothelial growth factor (VEGF) are involved in the formation of new blood vessels required for placental development and function. The hallmark of preeclampsia is similar to the toxicities related to antiangiogenesis therapy. VEGF inhibitors or antagonists promote vasoconstriction, hypertension and proteinuria. VEGF plays a role in attenuating hypertension and improving kidney damage in an animal model; however, the mechanisms underlying this effect remain poorly defined. The aim of this paper is to summarize recent advances in VEGF-mediated signaling and the target molecules, and provide new insights into treatment strategies for preeclampsia. METHOD OF STUDY: This article reviews the English-language literature for pathogenesis of preeclampsia based on VEGF signaling and hypertension. RESULTS: VEGF activates downstream signaling molecules, including Ca(2+)/CAMKK, Rac1/NOX, ROS/ERK, Ezrin/Calpain/PI3K/Akt, PLCγ/PKC and Src/HSP90. Among these signalings, important pathways for receptor-triggered intracellular signaling are (1) the PI3K/Akt-dependent, (2) the PLCγ-dependent and (3) the ERK/Egr-1-dependent pathway. VEGF is closely involved in receptor-activated signaling events, leading to eNOS-dependent NO synthesis and eNOS-independent endothelial cell proliferation, respectively, and thus modulates vasoactive function and angiogenic response. CONCLUSION: This review highlights the potential role of NO in vasodilation, while stress-related ERK activation might act to strengthen angiogenesis, migration and proliferation. We discuss the similarity between preeclampsia and VEGF-targeted therapy-induced hypertension.

RESUMO

We report a case of ovarian carcinoid tumor that recurred with multiple liver metastases and was successfully treated with chemoembolization. A 76-year-old woman was admitted to our hospital presented with abdominal distension and abnormal uterine bleeding for about 6 months. She presented with hyperestrogenic and androgenic manifestations such as vaginal bleeding with endometrial hyperplasia and hirsutism. Magnetic resonance (MR) imaging revealed a large solid and cystic ovarian tumor of 17 cm at maximum diameter. On the basis of the clinical diagnosis of sex cord stromal tumor containing a mature cystic teratoma, she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. The pathology report revealed that the mass in the left ovary was a carcinoid tumor, insular type, with mature cystic teratoma. Two years after surgical treatment, multiple liver metastases were revealed by abdominal CT. Hepatic arterial infusion of cisplatin was performed for 2 courses, and multiple metastatic nodules have remarkably reduced. No established chemotherapy or radiation therapy treatments are currently available for recurrent or advanced carcinoid tumors. Our paper suggests that chemoembolization with cisplatin may be effective in treatment of patients with multiple liver metastases of ovarian carcinoid tumor.

RESUMO

A 70-year-old man presented with sudden onset of global aphasia and right hemiplegia. Brain MRI revealed occlusion of the left middle cerebral artery. He was diagnosed as having a hyperacute cerebral infarction. Intravenous thrombolytic therapy was started, and the neurological symptoms were resolved after 11 h. Echocardiography showed a mobile mass in the left atrium, suspicious of a myxoma. The tumor was resected and pathologically diagnosed as a myxoma. In this patient, intravenous thrombolytic therapy was effective, and no adverse effects were observed. This suggests that, even with complications of myxoma, thrombolytic therapy can be considered if there are no contraindications.
