Abdominal lymphatic pathway in Fontan circulation using non-invasive magnetic resonance lymphangiography.

Lymphatic congestion is known to play an important role in the development of late Fontan complications. This study aimed to (1) develop a gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) contrast three-dimensional heavily T2-weighed MR technique that can detect abnormal lymphatic pathway in the abdomen while simultaneously evaluating hepatocellular carcinoma (HCC) and to (2) propose a new classification of abnormal abdominal lymphatic pathway using a non-invasive method in adults with Fontan circulation. Twenty-seven adults with Fontan circulation who underwent Gd-EOB-DTPA abdominal MR imaging were prospectively enrolled in this study. We proposed MR lymphangiography that suppresses the vascular signal on heavily T2-weighted imaging after EOB contrast. The patients were classified as follows: grade 1 with almost no lymphatic pathway, grade 2 with a lymphatic pathway mainly around the bile duct and liver surface, and grade 3 with a lymphatic pathway mainly around the vertebral body and inferior vena cava. The grade 3 group showed the lowest oxygen saturation level, highest central venous pressure, highest incidence of massive ascites, HCC, and focal nodular hyperplasia. This group also tended to have patients with the oldest age and highest cardiac index; however, the difference was not statistically significant. As for the blood test, the grade 3 group showed the lowest platelet count and serum albumin level and the highest fibrosis-4 index. A novel technique, Gd-EOB-DTPA MR lymphangiography, can detect abnormal abdominal lymphatic pathways in Fontan circulation, which can reflect the severity of failing Fontan.

Treatment of advanced heart failure in adults with congenital heart disease: a narrative review and clinical cases.

Background and Objective: The number of adults with congenital heart disease (ACHD) is increasing worldwide. Almost all congenital cardiac lesions can be successfully treated due to the progress in neonatal surgery and pediatric cardiology with a high likelihood of surviving until adulthood. However, ACHD frequently develop sequelae related to the initial cardiac anomaly. Heart failure (HF) is one of the most common complications associated with a high morbidity and mortality. Methods: The authors did search the PubMed database regarding relevant content covering publications up to March 2022. Relevant manuscripts were classified according to the impact factor of the journal, being a guideline manuscript, a position paper by a society or a comprehensive review of the current literature. Key Content and Findings: Optimal HF treatment remains an unmet need in ACHD. In particular, advanced HF therapy with cardiac resynchronization therapy, ventricular assist devices or organ transplantation is still very different and more specific in ACHD compared to non-ACHD. This review aims to compile international views and evidence from the literatures on the treatment of advanced HF in ACHD. Current challenges, but also the success of different treatment strategies in ACHD are illustrated by clinical cases. Conclusions: The main finding of the review is that data is still scarce regarding ACHD with advanced HF and international efforts to collect data regarding these patients needed to improve the current standard of care.

Status of adult outpatients with congenital heart disease in Japan: The Japanese Network of Cardiovascular Departments for Adult Congenital Heart Disease Registry.

BACKGROUND: The Japanese Network of Cardiovascular Departments for Adult Congenital Heart Disease (JNCVD-ACHD) was founded in 2011 for the lifelong care of adult patients with congenital heart disease (ACHD patients). This network maintains the first Japanese ACHD registry. METHODS AND RESULTS: From 2011 to 2019, the JNCVD-ACHD registered 54 institutions providing specialized care for ACHD patients in 32 of the 47 prefectures in Japan. The registry collected data on the disease profile for 24,048 patients from 50 institutions and the patient characteristics for 9743 patients from 24 institutions. The most common ACHDs were atrial septal defect (20.5 %), ventricular septal defect (20.5 %), tetralogy of Fallot (12.9 %), and univentricular heart (UVH)/single ventricle (SV; 6.6 %). ACHD patients without biventricular repair accounted for 37.0 % of the population. Also examined were the serious anatomical and/or pathophysiological disorders such as pulmonary arterial hypertension (3.0 %) including Eisenmenger syndrome (1.2 %), systemic right ventricle under biventricular circulation (sRV-2VC; 2.8 %), and Fontan physiology (6.0 %). The sRV-2VC cases comprised congenitally corrected transposition of the great arteries without anatomical repair (61.9 %) and transposition of the great arteries with atrial switching surgery (38.1 %). The primary etiology (86.4 %) for Fontan physiology was UVH/SV. In addition, developmental/chromosomal/genetic disorders were heterotaxy syndromes (asplenia, 0.9 %; polysplenia, 0.7 %), trisomy 21 (4.0 %), 22q11.2 deletion (0.9 %), Turner syndrome (0.2 %), and Marfan syndrome (1.1 %). CONCLUSIONS: Although the specific management of ACHD has systematically progressed in Japan, this approach is still evolving. For ideal ACHD care, the prospective goals for the JNCVD-ACHD are to create local networks and provide a resource for multicenter clinical trials to support evidence-based practice.

Percutaneous aspiration embolectomy is beneficial for pulmonary thromboembolism in adult patients with Fontan circulation.

In patients with acute pulmonary thromboembolism (PTE), increased pulmonary vascular resistance (PVR) due to thrombus sometimes causes hemodynamic instability, requiring reperfusion therapy with drugs, surgery, or catheterization. In particular, patients with Fontan circulation, which is strongly affected by PVR, are prone to hemodynamic instability. Moreover, these patients sometimes have bleeding complications such as hemoptysis and intrathoracic adhesions, following multiple prior thoracotomies, making it difficult to choose pharmacotherapy. Percutaneous aspiration embolectomy (PAE) is a useful treatment option because it minimizes bleeding complications, is less invasive, and more rapid than surgery, and is easy to perform. Herein, we report two cases of Fontan patients having PTE treated with PAE. In Case 1, a 21-year-old man with a history of a Fontan procedure suddenly developed acute PTE, for which anticoagulants were administered immediately. However, his condition was refractory to treatment and he underwent PAE on the third day of illness. In Case 2, a 28-year-old woman with a history of Fontan procedure who had been on anticoagulants, developed acute PTE on the ninth postpartum day, and underwent PAE on the day of onset. In both cases, the respiratory condition improved, and re-treatment for PTE was not required. Learning objective: Fontan patients with acute pulmonary thromboembolism often require reperfusion therapy because they can easily become hemodynamically unstable due to increased pulmonary vascular resistance. For them, who often have adhesions following multiple prior thoracotomies and bleeding complications, percutaneous aspiration embolectomy may be effective as it has minimal bleeding risk and is minimally invasive, rapid, and straightforward.

Metabolic syndrome and coronary artery disease in adults with congenital heart disease.

In adults with congenital heart disease (ACHD), conditions acquired with aging, such as metabolic syndrome, hypertension, diabetes mellitus, and obesity, can negatively influence the original cardiovascular disease. Metabolic syndrome has a higher prevalence in ACHD than in the general population. In contrast, coronary artery disease shows a similar prevalence in adults with acyanotic CHD and the general population, while adults with cyanotic CHD, even after repair, have an even lower incidence of coronary artery disease than the general population/adults with acyanotic CHD. However, even in those with cyanotic CHD, coronary artery disease can develop when they have risk factors such as obesity, dyslipidemia, hypertension, diabetes mellitus, smoking habit, or limited exercise. The prevalence of risk factors for cardiovascular disease is similar between ACHD and the general population, but an increased risk of coronary atherosclerosis has been observed for congenital coronary artery anomalies, dextro-transposition of the great arteries after arterial switch operation, Ross procedure, and coarctation of the aorta. Aortopathy may be an additional risk factor for cardiovascular disease. As ACHD have other abnormalities that may make the heart more vulnerable to both the development of atherosclerosis and adverse cardiovascular sequelae, regular evaluation of their cardiovascular disease risk status is recommended. Metabolic syndrome is more common among ACHD than in the general population, and may therefore increase the future incidence of atherosclerotic coronary artery disease even in ACHD. Thus, ACHD should be screened for metabolic syndrome to eliminate risk factors for atherosclerotic coronary artery disease.

A case of endosalpingiosis in the lymph nodes of the mesocolon.

BACKGROUND: Endosalpingiosis in the lymph nodes of the mesocolon is very rare. We reported a case with appendiceal endometriosis who had endosalpingiosis in the lymph nodes of the mesocolon that was found during laparoscopic ileocecal resection. CASE PRESENTATION: The patient was a 44-year-old woman who had visited a physician for fever, bloody stool, and abdominal pain 1 year earlier. She was diagnosed with ulcerative colitis on colonoscopy, and symptoms improved with oral treatment. A colonoscopy performed 2 months after diagnosis detected a hard, 20-mm submucosal tumor (SMT) in the cecum. On abdominal contrast CT, an intensely stained mass, including a low-density region, was observed in the cecum. A boring biopsy was performed after mucosal resection of the cecal SMT at our hospital, but diagnosis could not be made. Since the possibility of a malignant lesion could not be ruled out, laparoscopic ileocecal resection was performed. In the resected specimen, a 29 × 27 × 21-mm mass was present in the appendicular root. On histopathological examination, appendiceal endometriosis and endosalpingiosis in the lymph nodes around the ileocolic artery were observed. The postoperative course was favorable, and the patient was discharged 7 days after surgery. CONCLUSION: Differentiation of endosalpingiosis in lymph nodes in the mesocolon from lymph node metastasis of adenocarcinoma is important in patients with an abdominal mass.

Hyperosmolarity and Increased Serum Sodium Concentration Are Risks for Developing Hypertension Regardless of Salt Intake: A Five-Year Cohort Study in Japan.

The potential contribution of serum osmolarity in the modulation of blood pressure has not been evaluated. This study was done to examine the relationship between hyperosmolarity and hypertension in a five-year longitudinal design. We enrolled 10,157 normotensive subjects without diabetes who developed hypertension subsequently as determined by annual medical examination in St. Luke's International Hospital, Tokyo, between 2004 and 2009. High salt intake was defined as >12 g/day by a self-answered questionnaire and hyperosmolarity was defined as >293 mOsm/L serum osmolarity, calculated using serum sodium, fasting blood glucose, and blood urea nitrogen. Statistical analyses included adjustments for age, gender, body mass index, smoking, drinking alcohol, dyslipidemia, hyperuricemia, and chronic kidney disease. In the patients with normal osmolarity, the group with high salt intake had a higher cumulative incidence of hypertension than the group with normal salt intake (8.4% versus 6.7%, p = 0.023). In contrast, in the patients with high osmolarity, the cumulative incidence of hypertension was similar in the group with high salt intake and in the group with normal salt intake (13.1% versus 12.9%, p = 0.84). The patients with hyperosmolarity had a higher incidence of hypertension over five years compared to that of the normal osmolarity group (p < 0.001). After multiple adjustments, elevated osmolarity was an independent risk for developing hypertension (OR (odds ratio), 1.025; 95% CI (confidence interval), 1.006-1.044), regardless of the amount of salt intake. When analyzed in relation to each element of calculated osmolarity, serum sodium and fasting blood glucose were independent risks for developing hypertension. Our results suggest that hyperosmolarity is a risk for developing hypertension regardless of salt intake.

Quality indicators of palliative care for acute cardiovascular diseases.

BACKGROUND: Although recent attention to palliative care for patients with cardiovascular diseases has been increasing, there are no specific recommendations on detailed palliative care practices. We proceed on a discussion of the appropriateness and applicability of potential quality indicators for acute cardiovascular diseases according to our previous systematic review. METHODS: We created a multidisciplinary panel of 20 team members and 7 external validation clinicians composed of clinical cardiologists, a nutritionist, a physiotherapist, a clinical psychologist, a critical and emergent care specialist, a catheterization specialist, a primary care specialist, a palliative care specialist, and nurses. After crafting potential indicators, we performed a Delphi rating, ranging from "1 = minimum" to "9 = maximum". The criterion for the adoption of candidate indicators was set at a total mean score of seven or more. Finally, we subcategorized these indicators into several domains by using exploratory factor analysis. RESULTS: Sixteen of the panel members (80%) were men (age, 49.5 ± 13.7 years old). Among the initial 32 indicators, consensus was initially reached on total 23 indicators (71.8%), which were then summarized into 21 measures by selecting relatively feasible time variations. The major domains were "symptom palliation" and "supporting the decision-making process". Factor analysis could not find optimal model. Narratively-developed seven sub-categories included "presence of palliative care team", "patient-family relationship", "multidisciplinary team approach", "policy of approaching patients", "symptom screening and management", "presence of ethical review board", "collecting and providing information for decision-maker", and "determination of treatment strategy and the sharing of the care team's decision". CONCLUSION: In this study we developed 21 quality indicators, which were categorized into 2 major domains and 7 sub-categories. These indicators might be useful for many healthcare providers in the initiation and enhancement of palliative care practices for acute cardiovascular diseases in Japan.

The relationship between extracellular volume fraction in symptomatic adults with tetralogy of Fallot and adverse cardiac events.

BACKGROUND: To investigate the relationship between the extracellular volume fraction (ECV) measured using cardiac magnetic resonance (CMR) T1 mapping and cardiac events in symptomatic adults with tetralogy of Fallot (TOF). METHODS: A total of 60 consecutive symptomatic adults (35.4±13.8 years old) with repaired TOF who were in New York Heart Association functional class 2-4 were prospectively enrolled. Native T1 values and ECV of the free walls of the right ventricle (RV), the left ventricle, and the ventricular septum were obtained by CMR T1 mapping using a 3.0T scanner and the saturation recovery method. Correlations between T1 mapping measurements, conventional parameters, and predictors of adverse cardiac events were analyzed. The patients with episodes of only atrial arrhythmia were excluded. RESULTS: Significant correlations were observed between RV functional parameters, RV-ECV, and septum-ECV. Follow-up period was 747.1±315 days and 13 patients had cardiac events: Acute heart failure and/or sustained ventricular tachycardia occurred in 8 patients and 5 patients underwent cardiac surgery. Cox-hazard analysis revealed that septum-ECV and RV-ECV were predictors of adverse events (hazard ratio of septum-ECV and RV-ECV: 1.41 and 1.19, 95% CI: 1.05-1.89, 1.004-1.41 with p-values of 0.02, and 0.045, respectively). Adults with septum-ECV >29.0% and RV ejection fraction (EF) <45.0% were more likely to experience cardiac events (log rank test: p<0.043). CONCLUSIONS: RV-ECV and septum-ECV correlate with RV functional parameters. Biventricular ECVs can be predictors of adverse cardiac events in adults with TOF. In particular, the combination of septum-ECV and RVEF was a useful predictor, compared to the use of a single CMR parameter.

Current status of venous thromboembolism development during the perioperative period for colorectal cancer, its prevention with enoxaparin, and monitoring methods.

Background: There is a high incidence of venous thromboembolism (VTE) during the perioperative period for cancer. Therefore, there is an urgent need to elucidate the perioperative onset and appropriate prophylaxis for VTE. Purpose: VTE during the perioperative period for colorectal cancer was evaluated by lower limb venous ultrasonic examinations (lower limb echo) under enoxaparin prophylaxis. We also examined the relationship between hemorrhagic adverse events and anti-Xa factor activity. Patients and methods: Eighty-three subjects who underwent lower limb echo during the perioperative period for colorectal cancer were prospectively included. Enoxaparin was administered for 5 days, from day 1 to day 5 after surgery. Lower limb echo was performed before surgery and on day 5 after surgery. The activated partial thromboplastin time, D-dimer levels, and anti-Xa factor activity were measured before surgery and on days 1, 3, 5, 7, and 9 after surgery. Results: VTEs before surgery were observed on lower limb echo for 16 patients (19.2%). Three patients (3.6%) had a new thrombus during the perioperative period. The preoperative D-dimer level was an independent prognostic factor for newly formed postoperative VTEs (p=0.0036; odds ratio, 19.37). Three patients (3.6%) had hemorrhagic events; however, there was no significant trend for anti-Xa factor activity. Conclusion: VTE prevention using enoxaparin was relatively safe, and D-dimer measurements before surgery were useful for predicting perioperative VTE.

High rate of calories from protein is associated with higher prevalence of hypertension.

The desirable distribution of three major nutrients intake to prevent hypertension is not established. This study is to clarify the relationship between the prevalence of hypertension and the rate of intake of three major nutrients. This is a large-scale cross-sectional study. We analyzed Japanese subjects who had their annual medical examination at St Luke's International Hospital, Tokyo from January 2004 to June 2010. The amount of three major nutrients and salt intake were checked by a questionnaire method, and this study clarified the relationship between the prevalence of hypertension and the rate of three major nutrients with adjustment for age, sex, body mass index (BMI), smoking, dyslipidemia, diabetes mellitus, hyperuricemia, and salt intake. We analyzed 89,851 subjects. Of those, the number of hypertensive subjects was 13,926 (15.5%). The hypertensive group had significantly higher rate of calories from protein (19.7% vs. 19.4%, P < 0.001) but lower rate of calories from fat (16.1% vs. 16.4%, P < 0.001) than that in the non-hypertensive group. The rate of calories from carbohydrate was almost the same between the two groups (64.2% vs. 64.2%). After multiple adjustments, high rate of calories from protein was associated with high prevalence of hypertension (odds ratio: 1.011, 95% confidence interval (CI), 1.005-1.017), as well as aging, male, high BMI, smoking habits, dyslipidemia, diabetes mellitus, and hyperuricemia. High rate of calories from protein could be associated with high risk of hypertension. Therefore, protein-restricted diet may have a favorable effect in preventing hypertension and cardiovascular diseases.

Fasting blood glucose is predictive of hypertension in a general Japanese population.

OBJECTIVE: This study was conducted to identify whether higher fasting blood glucose levels is predictive of hypertension by a large-scale longitudinal design. METHODS: We conducted a retrospective 5-year cohort study using the data from 13 201 Japanese individuals who underwent annual medical examinations in 2004 and were reevaluated 5 years later. This study included individuals without diabetes or hypertension between ages 30 and 85 years in 2004. The cumulative incidences of hypertension over 5 years in each 10 mg/dl of fasting blood glucose levels were calculated. Moreover, we examined risk factors and calculated odds ratios (ORs) for developing hypertension after adjustments for age, sex, BMI, smoking and drinking habits, dyslipidemia, chronic kidney disease, serum uric acid, and fasting blood glucose levels by logistic regression analyses. RESULTS: We analyzed 10 157 participants (age: 48.9 ±â€Š10.7 years; 43.4% men) without diabetes or hypertension in 2004. After multiple adjustments, higher baseline blood glucose level is an independent risk for hypertension (OR: 1.176; 95% CI 1.086-1.275), as well as aging, women, higher BMI, drinking habits, and higher serum uric acid. After stratifying by sex, higher baseline blood glucose level is an independent risk for hypertension both in women (OR: 1.295; 95% CI 1.135-1.478) and men (OR: 1.108; 95% CI 1.001-1.227). When we conducted the same analysis using glycated hemoglobin instead of blood glucose, glycated hemoglobin was not a risk for hypertension. CONCLUSION: Higher fasting blood glucose is an independent risk for developing hypertension. Further studies are needed to determine if treatment for elevated blood glucose can prevent developing hypertension.

Mode of death and predictors of mortality in adult Fontan survivors: A Japanese multicenter observational study.

BACKGROUND: Mortality rates may be high in adult Fontan patients; however, the clinical determinants remain unclear. PURPOSE: We conducted a prospective multicenter study of adult Fontan survivors to determine the 5-year mortality rate and clarify the determinants. METHOD AND RESULTS: We followed 600 adult Fontan survivors from 40 Japanese institutions (307 men, 28 ±â€¯7 years old, follow-up: 18 ±â€¯6 years). The New York Heart Association (NYHA) functional class I and II was 51% and 42%, respectively. During the follow-up period of 4.1 ±â€¯1.6 years, 33 patients died, and the 5-year survival rate was 93.5%. The mode of death was heart failure in 11 patients (34%), arrhythmia or sudden death in 8 (24%), cancer in 5 (15%), perioperative problems and hemostatic problems in 4 each (12% for each), and infection in 1 (3%). Left isomerism, prior hospitalization, protein losing enteropathy (PLE), pulmonary arteriovenous fistulae, NYHA functional class, impaired hemodynamics, hyponatremia, hepatorenal dysfunction, and use of diuretics were associated with a high mortality rate (p < 0.05-0.0001). Further, PLE (hazard ratio [HR]: 14.4), left isomerism (HR: 3.5), and NYHA (HR: 2.4) independently predicted a high 5-year high mortality (p < 0.05 for all). The incidence of cancer-related mortality increased markedly with age >40 years. CONCLUSIONS: Majority of the Japanese adult Fontan survivors had good functional status, with an acceptable 5-year survival rate. However, the significant prevalence of non-cardiac mortality highlights Fontan pathophysiology as a multi-organ disease that requires a multidisciplinary management strategy to improve the long-term outcome.

Different Risk for Hypertension, Diabetes, Dyslipidemia, and Hyperuricemia According to Level of Body Mass Index in Japanese and American Subjects.

Obesity is a risk factor for hypertension, diabetes mellitus (DM), dyslipidemia, and hyperuricemia. Here, we evaluated whether the same body mass index (BMI) for the U.S. population conferred similar metabolic risk in Japan. This was a cross-sectional analysis involving 90,047 Japanese adults (18⁻85 years) from St. Luke's International Hospital, Tokyo, Japan and 14,734 adults from National Health and Nutrition Examination Survey (NHANES) collected in the U.S. We compared the prevalence of hypertension, DM, dyslipidemia, and hyperuricemia according to BMI in Japan and the U.S. The prevalence of hypertension, DM, and dyslipidemia were significantly higher in the U.S. than Japan, whereas the prevalence of hyperuricemia did not differ between countries. Higher BMI was an independent risk factor for hypertension, DM, dyslipidemia, and hyperuricemia both in Japan and in the U.S. after adjusting for age, sex, smoking and drinking habits, chronic kidney disease, and other cardiovascular risk factors. The BMI cut-off above which the prevalence of these cardio-metabolic risk factors increased was significantly higher in the U.S. than in Japan (27 vs. 23 kg/m² for hypertension, 29 vs. 23 kg/m² for DM, 26 vs. 22 kg/m² for dyslipidemia, and 27 vs. 23 kg/m² for hyperuricemia). Higher BMI is associated with an increased prevalence of hypertension, DM, dyslipidemia, and hyperuricemia both in Japan and U.S. The BMI cut-off above which the prevalence of cardio-metabolic risk factors increases is significantly lower in Japan than the U.S., suggesting that the same definition of overweight/obesity may not be similarly applicable in both countries.

Elevated serum uric acid increases risks for developing high LDL cholesterol and hypertriglyceridemia: A five-year cohort study in Japan.

BACKGROUND: High serum uric acid (SUA) is associated with the dyslipidemia, but whether hyperuricemia predicts an increase in serum low-density lipoprotein (LDL) cholesterol is unknown. This study is to evaluate whether an elevated SUA predicts the development of high LDL cholesterol as well as hypertriglyceridemia. METHODS: This is a retrospective 5-year cohort study of 6476 healthy Japanese adults (age, 45.7 ±â€¯10.1 years; 2.243 men) who underwent health examinations at 2004 and were reevaluated in 2009 at St. Luke's International Hospital, Tokyo, Japan. Subjects were included if at their baseline examination they did not have hypertension, diabetes mellitus, dyslipidemia, chronic kidney disease, or if they were on medication for hyperuricemia and/or gout. The analysis was adjusted for age, body mass index (BMI), smoking and drinking habits, baseline estimated glomerular filtration rate (eGFR), baseline SUA and SUA change over the 5 years. RESULTS: High baseline SUA was an independent risk for developing high LDL cholesterol both in men (OR: 1.159 per 1 mg/dL increase, 95% CI:1.009-1.331) and women (OR: 1.215, 95% CI:1.061-1.390). Other risk factors included a higher baseline LDL cholesterol, higher BMI, and higher baseline eGFR (the latter two in women only). Increased SUA over 5 years were also independent risks for developing high LDL cholesterol and hypertriglyceridemia, but not for low high-density lipoprotein (HDL) cholesterol. CONCLUSIONS: This is the first study to report that an elevated SUA increases the risk for developing high LDL cholesterol, as well as hypertriglyceridemia. This may shed light into the role of SUA in cardiovascular disease.

Liver Cirrhosis and/or Hepatocellular Carcinoma Occurring Late After the Fontan Procedure　- A Nationwide Survey in Japan.

BACKGROUND: Fontan-associated liver disease (FALD) is an important late complication involving liver dysfunction, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC), in patients undergoing the Fontan procedure. However, the prevalence, clinical manifestation, and methods of diagnosis of FALD are still not well established.Methods and Results:This study comprised 2 nationwide surveys in Japan. First, the prevalence of LC and/or HCC in patients undergoing the Fontan procedure was determined. Second, clinical manifestations in patients with LC and/or HCC were analyzed, along with data from blood tests, echocardiography, and right heart catheterization. In the 1st survey, of the 2,700 patients who underwent the Fontan procedure, 31 were diagnosed with LC and/or HCC (1.15%), and 5 died due to liver diseases (mortality: 0.19%). In the 2nd survey, data were collected from 17 patients (12 with LC, 2 with HCC, and 3 with LC+HCC. Of these 17 patients, 5 died (mortality: 29.4%). The mean age at diagnosis of LC and HCC was 23 and 31 years, respectively. Computed tomography followed by ultrasound was most frequently used for diagnosis. Blood tests revealed low platelet counts, increased hemoglobin, aspartate aminotransferase, γ-guanosine triphosphate, and total bilirubin levels, and an elevated international normalized ratio of prothrombin time. CONCLUSIONS: LC and/or HCC in patients undergoing the Fontan procedure were not rare late complications and were associated with high mortality rates.

Body composition, appetite-related hormones, adipocytokines, and heart failure in adult patients with congenital heart disease: A preliminary study.

OBJECTIVES: To assess body composition and relationships among body composition, appetite-related hormones, adipocytokines, and heart failure (HF) in adult patients with congenital heart disease (CHD). PATIENTS: This prospective study enrolled 46 consecutive adult patients with CHD and 12 age-matched healthy controls. The patients and control subjects were divided into four groups: 13 patients with Fontan circulation (group A), 16 patients with cyanosis (group B), 17 patients who previously underwent biventricular repair (group C), and 12 age-matched healthy controls. DESIGN: Body composition was measured using InBody730, and levels of appetite-related hormones (ghrelin and leptin) and adipocytokines (leptin, interleukin-6, and tumor necrosis factor-α) were determined. Relationships of these measurements between severe HF, defined as New York Heart Association functional class III-IV and/or recent repeated unscheduled hospitalizations due to HF, were examined using univariate logistic analysis. RESULTS: Mean patient age was 32.1 ± 7.4 years. The skeletal muscle mass was significantly decreased in groups A and B compared with that in controls. Interestingly, ghrelin levels in groups A and B were also significantly lower than those in controls. Univariate logistic analysis revealed that ghrelin level, percent body fat, and pulse oximetric oxygen saturation were significantly associated with severe HF. CONCLUSIONS: Patients with Fontan circulation and those with cyanosis might be at a risk of sarcopenia. Despite the decreased skeletal muscle mass and increased body fat, ghrelin levels in these patients were decreased. These changes might have a negative impact on HF in these patients.

Case of idiopathic and complete appendiceal intussusception.

Appendiceal intussusception is a rare disease in which the appendix invaginates into the cecum. It is often caused by organic diseases. The present case involved an appendiceal intussusception without an organic disease, and laparoscopic resection of part of the cecum was performed. Appendiceal intussusception has various causes, including malignant diseases. Therefore, diagnosis and selection of operative method are complex and could potentially lead to an excessively invasive option. By performing SILS with a multiuse single-site port, we were able to provide an appropriate, non-invasive treatment that had a good esthetic outcome.

Uric Acid Is a Strong Risk Marker for Developing Hypertension From Prehypertension: A 5-Year Japanese Cohort Study.

Prehypertension frequently progresses to hypertension, a condition associated with high morbidity and mortality from cardiovascular diseases and stroke. However, the risk factors for developing hypertension from prehypertension remain poorly understood. We conducted a retrospective cohort study using the data from 3584 prehypertensive Japanese adults (52.1±11.0 years, 2081 men) found to be prehypertensive in 2004 and reexamined in 2009. We calculated the cumulative incidences of hypertension over 5 years, examined risk factors, and calculated odds ratios (ORs) for developing hypertension after adjustments for age, sex, body mass index, smoking and drinking habits, baseline systolic and diastolic blood pressure, pulse rate, diabetes mellitus, dyslipidemia, chronic kidney disease, and serum uric acid levels. The additional analysis evaluated whether serum uric acid (hyperuricemia) constituted an independent risk factor for developing hypertension. The cumulative incidence of hypertension from prehypertension over 5 years was 25.3%. There were no significant differences between women and men (24.4% versus 26.0%; P=0.28). The cumulative incidence of hypertension in subjects with hyperuricemia (n=726) was significantly higher than those without hyperuricemia (n=2858; 30.7% versus 24.0%; P<0.001). After multivariable adjustments, the risk factors for developing hypertension from prehypertension were age (OR, 1.023; P<0.001), female sex (OR, 1.595; P<0.001), higher body mass index (OR, 1.051; P<0.001), higher baseline systolic (OR, 1.072; P<0.001) and diastolic blood pressure (OR, 1.085; P<0.001), and higher serum uric acid (OR, 1.149; P<0.001). Increased serum uric acid is a strong risk marker for developing hypertension from prehypertension. Further studies are needed to determine whether treatment of hyperuricemia in prehypertensive subjects could impede the onset of hypertension.
