Brachiocephalic artery dissection is a marker of stroke after acute type A aortic dissection repair.

OBJECTIVE: Postoperative stroke is a serious unsolved complication after acute type A aortic dissection (ATAAD) repair. We investigated the incidence and risk factors of stroke, and hypothesized that dissection of supra-aortic vessels is an important risk factor of this morbidity. METHODS: Between 2012 and 2019, 202 (56% men, median age 68 years) patients with ATAAD underwent surgical repair. Clinical data, image findings, method of circulatory support, and repair technique were retrospectively investigated to explore the risk factor of postoperative stroke. RESULTS: Of the 202 patients, operative mortality was 6% and the incidence of postoperative stroke was 12% (n = 25). Brachiocephalic artery (BCA) dissection was associated with a higher risk of stroke (odds ratio, 3.89; 95% confidence interval, 1.104-13.780; p = .035) having no relation to the presence or absence of left common carotid artery dissection. Preoperative malperfusion syndrome, circulatory arrest time, isolated cerebral perfusion time, repair technique (total arch replacement), and femoral artery perfusion alone were not related to the incident rate of postoperative stroke. Stroke occurred in both hemispheres, regardless of the laterality of carotid artery dissection. CONCLUSION: BCA dissection was an independent risk factor of stroke after ATAAD repair.

Successful combination treatment with transcatheter balloon atrioseptostomy and bilateral pulmonary artery banding in a collapsed preterm neonate.

There has been an increase in the use of extracorporeal membrane oxygenation for severe neonatal cardiac failure. However, the frequency of complications is high, particularly in preterm and low-birth-weight neonates. Herein, we present combination treatment with transcatheter balloon atrioseptostomy and bilateral pulmonary artery banding in a collapsed preterm neonate. This strategy can be an alternative to circulatory support using extracorporeal membrane oxygenation.

Long-term clinical outcomes of the Toronto stentless porcine valve: 15-year results from dual centers.

BACKGROUND AND AIM OF THE STUDY: The purpose of this study is to examine the long-term durability of the Toronto stentless porcine valve (SPV) in the aortic position (St Jude Medical, Minneapolis, MN). METHODS: We assessed the long-term clinical outcomes of 515 patients with aortic valve replacement (AVR) with the Toronto SPV from 1987 to 2001 at two centers, excluding early (<30 days) death. Median follow-up was 11.5 years (maximum 19.0 years). RESULTS: Average age was 64.2 ± 10.8 years, and females were 34% (173/515). The incidence of prosthesis-patient mismatch was low, 10.9%. Overall survival was 90.7 ± 1.3%, 75.4 ± 2.0%, and 56.8 ± 3.2% at 5, 10, and 15 years, respectively after surgery. Over the follow-up duration, 116 patients (23%) underwent repeated AVR: 90 for structural valve deterioration (SVD), 12 for endocarditis, 10 nonstructural valve dysfunction (10 aortic regurgitation due to aorta dilatation), and four for other reasons. The cumulative incidence of repeated AVR with death as a competing risk was 1.4% (95% confidence interval [CI], 0.6-2.7), 11.1% (95% CI, 8.4-14.2), and 34.4% (95% CI, 28.8-40.2) at 5, 10, and 15 years, respectively. Reoperative mortality was 5.2% (6/116). In SVD, the regurgitation type was dominant (82%). CONCLUSIONS: The Toronto SPV is associated with excellent survival and durability during the first decade of follow-up. However, regurgitation type of SVD increases from 10 years after operation with acceptable reoperative mortality. These findings may assist with prosthesis selection and reintervention strategy for failing stentless bioprosthesis.

Seroma formation after modified Blalock-Taussig shunt which caused shock due to pulmonary vein compression.

Seroma formation is a relatively rare complication seen after a modified Blalock-Taussig shunt. Herein, we report a rare case of seroma formation on the posterior aspect of the left atrium without it touching the graft, and presenting with shock, due to pulmonary vein compression.

The AB Portable Driver Generates Higher Drive-Line Pressures Possibly Leading to Accelerated Hemolysis.

The AB5000 Circulatory Support System is paracorporeal pulsatile ventricular assist device. The AB Portable Driver is a portable console for this system. We experienced two cases with accelerated hemolysis while receiving support by the AB Portable Driver. The purpose of this study was to clarify the mechanical differences associated with the hemolysis between the AB5000 console and the AB Portable Driver. The mock circulatory system modeled by an AB5000 ventricle and a blood sampling bag of vinyl chloride was run with an AB5000 console or AB Portable Driver. The peak drive-line pressure, the mean arterial cannula pressure and the pumping rate of the VAD were recorded. The AB5000 console generated a peak drive-line pressure of 280-300 mm Hg in LVAD mode and 210-220 mm Hg in RVAD mode, approximately 100 mm Hg lower than officially documented. In contrast, the AB Portable Driver generated pressures of 310-330 mm Hg in LVAD mode and 230-250 mm Hg in RVAD mode, 65-95 mm Hg higher than officially documented. The AB Portable Driver console generates higher drive-line pressures than the AB5000 console, possibly explaining the accelerated hemolysis.

[Relationship between fruit and vegetable gardening and health-related factors: male community gardeners aged 50-74 years living in a suburban area of Japan].

Objectives　The aims of the study were as follows: 1) to investigate the relationship between community fruit and vegetable (FV) gardening and perceived changes in health-related factors by utilizing community gardens and 2) to determine the relationship of community FV gardening and other types of gardening on health-related factors among men aged 50-74 years living in a suburban area of Japan.Methods　In this cross-sectional study, we targeted men aged 50-74 years living in a city in Gunma Prefecture. A survey solicited demographic characteristics, FV gardening information, and health-related factors [BMI, self-rated health status, FV intake, physical activity (PA), and perceived neighborhood social cohesion (PNSC)]. The participants were divided into three groups: community gardeners, other types of gardeners, and non-gardeners. Items related to community gardening and perceived changes in health-related factors were presented only to community gardeners. The relationship between community gardening and perceived changes in health-related factors were analyzed by computing correlation coefficients. The relationships between FV gardening and specific health-related factors were analyzed by logistic regression modeling.Results　Significant positive correlations were observed between community FV gardening (the frequency of community gardening, the product of community gardening time and frequency of community gardening) and perceived changes in health-related factors (frequency of FV intake, amount of FV intake, and PA). The logistic regression models showed that 1) the number of participants with ≥23 METs h/week of PA was significantly greater among community gardeners than among non-gardeners; 2) the number of participants whose frequency of total vegetable intake, total vegetable intake (excluding juice), and total FV intake (excluding juice) was ≥5 times/day was significantly greater among other types of gardeners than non-gardeners; 3) participants with scores ≥ the median of PNSC were significantly greater among other types of gardeners than non-gardeners; and 4) participants who spent ≥4 hours/day sitting were significantly fewer among other types of gardeners than non-gardeners.Conclusion　Higher frequency of community gardening appears to induce greater perceived positive changes on FV intake and PA. It was indicated that FV gardening in community gardens contributes to increased PA, whereas other types of FV gardening contribute to increased FV intake frequency and decreased sitting time. In the future, higher-quality studies-for example, intervention studies using more rigorous measurements-will be necessary.

[Surgical strategy and the results for hypoplastic left heart syndrome].

OBJECTIVE: We retrospectively reviewed our surgical results in patients with hypoplastic left heart syndrome( HLHS) to investigate the influence of surgical strategy on outcome. METHODS: Seventy-seven patients with classic HLHS were involved in this study. For the initial palliation, 23 patients underwent Norwood operation with modified Blalock-Taussig (BT) shunt, 23 patients underwent Norwood operation with right ventricle to pulmonary artery( RV-PA) shunt and 31 patients underwent bilateral pulmonary artery banding (BPAB). Surgical results, freedom from Fontan operation, hemodynamic data and incidence of complication after Fontan operation were compared between the 3 groups. RESULTS: BPAB group had more preoperative risk factors than Norwood group. Total actuarial survival was 62.4% at 1 year and 58.2% at 3 and 5 years, and there was no difference between the groups. Freedom from Fontan completion was 59.4% at 3 years and 48.7% at 5 years without difference between the groups. The incidence of intervention for pulmonary artery stenosis was higher in Norwood with RV-PA shunt group(52.9%). Hemodynamic data obtained by cardiac catheterization were similar in the 3 groups, however, end-systolic elastance, which represents ventricular contractility, was lower in Norwood with RV-PA group. CONCLUSIONS: Surgical results of Norwood with BT shunt and Norwood with RV-PA shunt were comparably satisfactory, however, there was possible concern of reduced ventricular contractility in RV-PA shunt group. BPAB was a effective and useful initial palliation in high risk cases.

Lipoprotein Apheresis Alleviates Treatment-Resistant Peripheral Artery Disease Despite the Normal Range of Atherogenic Lipoproteins: The LETS-PAD Study.

AIM: Peripheral artery disease (PAD) severely impairs patient prognosis and quality of life (QOL). Although lipoprotein apheresis (LA) has been applied to patients with PAD and elevated serum atherogenic lipoproteins, we hypothesized that LA can be effective for treating PAD even in patients with controlled serum lipoproteins through pleiotropic anti-atherosclerotic effects beyond lipoprotein removal. This study aimed to evaluate the efficacy of LA in patients with treatment-resistant PAD and controlled serum lipoproteins focusing on QOL. METHODS: In a single-arm prospective study, 30 patients with refractory PAD who had controlled serum lipoproteins underwent sequential LA sessions using dextran sulfate adsorption columns, aiming to complete 10 sessions. The ankle-brachial pressure index (ABI) and vascular QOL (VascuQOL) score were evaluated as the primary outcomes. Secondary outcomes included reactive hyperemia index (RHI) and biological antioxidant potential (BAP) as an endothelial function test and serum antioxidative-capacity evaluation, respectively. RESULTS: ABI significantly increased after LA sessions (pre-treatment 0.60±0.09 vs. post-treatment 0.65±0.13, p=0.023). Total VascuQOL score (3.7±1.1 vs 4.6±1.1, p＜0.001) and RHI (1.70±0.74 vs 2.34±1.76, p=0.023) significantly improved after the LA sessions. BAP tended to increase after the LA sessions, and the change reached statistical significance 3 months after treatment. CONCLUSION: ABI and QOL improved after a series of LA sessions in conventional treatment-resistant PAD patients with controlled serum lipoprotein levels. Increased antioxidative capacity and ameliorated endothelial function were observed after the LA treatment.

Successful endovascular treatment of a ruptured superior mesenteric artery in a patient with Ehlers‒Danlos syndrome.

The purpose of this study was to describe covered-stent treatment of a ruptured dissection of the superior mesenteric artery (SMA) in a patient with Ehlers‒Danlos syndrome. The patient was a 13-year-old girl initially presenting with abdominal pain. Dissection and rupture of the SMA were diagnosed on detailed examination. Conservative treatment was performed initially because open surgery was considered high risk. However, the abdominal pain recurred, and we decided to perform endovascular therapy. A coronary artery covered stent was placed in the true lumen to close the entry site of the dissection. The false lumen was obliterated using a post-dilation technique, completing treatment of the rupture. The patient recovered uneventfully after surgery. Classic-type Ehlers‒Danlos syndrome was diagnosed on the basis of physical findings and genetic analysis. The stent has remained adequately patent as of 2 years after surgery. This case report shows that dissection and rupture of the SMA can be treated successfully using a covered coronary artery stent in a patient with Ehlers‒Danlos syndrome.

A case of ventricular triple rupture after an acute myocardial infarction.

Cardiac rupture, such as ventricular free-wall rupture, ventricular septal perforation, and papillary muscle rupture, is a life-threatening complication of acute myocardial infarction. Herein, we report a very rare case of combining these three types of ventricular rupture. A 71-year-old woman underwent mitral valve replacement and left ventricular free-wall rupture repair after an acute myocardial infarction. She was transferred to our hospital under mechanical support by venoarterial extracorporeal membrane oxygenation and intra-aortic balloon pump due to circulatory collapse. Transthoracic echocardiography revealed a left-to-right shunt caused by ventricular septal perforation. The patient underwent endoventricular patch plasty for septal defect closure. Unfortunately, a prolonged postoperative course led to the development of multi-organ failure followed by fatal outcome on day 32 postoperatively. To our best knowledge, this is the first reported case of ventricular triple rupture associated with acute myocardial infarction.

Use of the index of pulmonary vascular disease for predicting long-term outcome of pulmonary arterial hypertension associated with congenital heart disease.

Aims: Limited data exist on risk factors for the long-term outcome of pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD-PAH). We focused on the index of pulmonary vascular disease (IPVD), an assessment system for pulmonary artery pathology specimens. The IPVD classifies pulmonary vascular lesions into four categories based on severity: (1) no intimal thickening, (2) cellular thickening of the intima, (3) fibrous thickening of the intima, and (4) destruction of the tunica media, with the overall grade expressed as an additive mean of these scores. This study aimed to investigate the relationship between IPVD and the long-term outcome of CHD-PAH. Methods: This retrospective study examined lung pathology images of 764 patients with CHD-PAH aged <20 years whose lung specimens were submitted to the Japanese Research Institute of Pulmonary Vasculature for pulmonary pathological review between 2001 and 2020. Clinical information was collected retrospectively by each attending physician. The primary endpoint was cardiovascular death. Results: The 5-year, 10-year, 15-year, and 20-year cardiovascular death-free survival rates for all patients were 92.0%, 90.4%, 87.3%, and 86.1%, respectively. The group with an IPVD of ≥2.0 had significantly poorer survival than the group with an IPVD <2.0 (P = .037). The Cox proportional hazards model adjusted for the presence of congenital anomaly syndromes associated with pulmonary hypertension, and age at lung biopsy showed similar results (hazard ratio 4.46; 95% confidence interval: 1.45-13.73; P = .009). Conclusions: The IPVD scoring system is useful for predicting the long-term outcome of CHD-PAH. For patients with an IPVD of ≥2.0, treatment strategies, including choosing palliative procedures such as pulmonary artery banding to restrict pulmonary blood flow and postponement of intracardiac repair, should be more carefully considered.

Influence of Prefecture-Level Yield of Not-for-Sale Vegetables on Vegetable Intake in Japan: A Natural Experiment.

Increased vegetable intake contributes to better health for people. The distribution of not-for-sale vegetables is an important source of vegetable intake in Japan. This study examined the impact of prefecture-level yield of not-for-sale vegetables on vegetable intake in Japan. This study regarded the increase in yield of not-for-sale Chinese cabbage in Nagano Prefecture in 2012 as a natural experiment. The years 2012 and 2016 were the large-scale survey years of the Japanese National Health and Nutrition Survey. Therefore, the effect of the change in prefecture-level yield of not-for-sale vegetables on vegetable intake was evaluated by comparing the changes in Chinese cabbage intake in Nagano between 2012 and 2016 with those of other prefectures classified in the same regional block as Nagano. Statistical analysis was performed using general linear models to examine the interaction of year and prefecture with Chinese cabbage intake. Consequently, the regression coefficient for the interaction term was -3.38 (95% CI, -9.59-2.83), that of the model adjusted for basic characteristics and energy intake was -2.99 (95% CI, -9.22-3.24), and that of the model adding health-related variables was -5.03 (95% CI, -12.40-2.34). The prefecture-level yield of not-for-sale vegetables typically had a minor effect on vegetable intake.

Relationships between Food Production Experience and the Behavior, Attitude, and Knowledge of Dietary Recommendations among Japanese Adults: A Cross-Sectional Study.

The Japanese Ministry of Agriculture, Forestry, and Fisheries proposed to educate more people in food production as one of the objectives of the Basic Plan for Food and Nutrition Education Promotion. This cross-sectional study aims to elucidate the relationship between food production experience (agricultural, forestry, and fishery experiences) and the behavior, attitude, and knowledge of dietary recommendations among Japanese adults. This study was conducted using data obtained from the "Survey on Dietary Habits and Agriculture, Forestry, and Fishery Experiences (2019)". This survey was conducted by mailing paper questionnaires to respondents aged 20-69 years living in 17 regions across Japan. The independent variable was food production experience. The dependent variables were each of the 13 goals of the dietary guidelines in Japan, the total score for adherence to the 13 items (low scores indicate good adherence), adherence to a Japanese-style diet, and four items on the attitude and knowledge of dietary recommendations. I also examined the association between the point in life the food production experience occurred and the above outcomes. The data obtained from 3461 participants aged 20 to 69 years were used for multivariate logistic and linear regression analyses. Food production experience was positively associated with an improved behavior, attitude, and knowledge of dietary recommendations among adults in Japan. The study found a strong relationship with food production experiences in adulthood.

Relationships among Local Agricultural Product Purchases, Self-Cooked Meal Consumption, and Healthy Eating Habits: A Cross-Sectional Study in a Town in Gunma, Japan.

This study examined whether the frequency of purchasing local agricultural products and the intake frequency of self-cooked meals were related to healthy eating habits. A cross-sectional study was conducted using anonymized data from the "Survey on health promotion and food-and-nutritional education" conducted in 2021 in Tamamura, Gunma, Japan, targeting residents aged 20-65. Logistic regression analyses were conducted using the purchasing frequency of local agricultural products (often/sometimes/rarely) and the intake frequency of self-cooked meals (almost every day/not every day) as independent variables. The dependent variables were the frequencies of breakfast (every day/not every day), balanced meal (two times/day or more/fewer than two times/day), and vegetable intake (two times/day or more/fewer than two times/day). The purchasing frequency of local agricultural products was positively related to the frequency of balanced meal and vegetable intake. Additionally, the intake frequency of self-cooked meals was positively related to the frequencies of breakfast, balanced meal, and vegetable intake. In conclusion, significant positive relationships of the purchasing frequency of local agricultural products and the intake frequency of self-cooked meals with healthy eating habits were confirmed.

Contribution of Agriculture to Health Promotion.

Agriculture has been an important source of the human diet throughout human history, but its relationship with human societies has transformed over the long course of more than 10,000 y. Urbanization and agricultural commercialization are significant among such changes and wield considerable impact on human diets, nutrition, and health. This paper presents four studies examining the influence of agriculture on diet and general health: 1) the impact of urban allotment gardening on human health and wellbeing in Japan, 2) the preference of people in Japan for collaborations between citizens' farms and food-support organizations 3) the linkages between dietary diversity and agriculture in Indonesia, and 4) food sources and child nutrition in the deforested frontiers of Cambodia.

Proposal of a new classification: "sealed type" postinfarction left ventricular free wall rupture.

OBJECTIVE: Postinfarction left ventricular free wall rupture (FWR) has been classified into blow-out type and oozing type. However, considering past papers, oozing type included the cases in which the bleeding had spontaneously stopped or sealed, and the distinction between blow-out type and oozing type was not always clear. We classified FWR into the BO type (combination of blow-out type and oozing type) with continuous bleeding and sealed type and clarified the pathophysiology of the sealed type. METHODS: Thirty-five patients who underwent surgical treatment for FWR during the past 21 years were retrospectively evaluated. RESULTS: Twenty-one patients (60%) were sealed. Comparing the sealed type with the BO type, the incidence of sudden collapse with acute onset was significantly lower (sealed type; 62%, BO type; 100%, P = 0.0118), and there were more cases of transport from outside the hospital (76%, 43%, P = 0.0453). Significantly few cases had electro-mechanical dissociation immediately before surgery (10%, 71%, P = 0.0001). In the sealed type, median sternotomy was performed in 9 patients (43%), and subxiphoid drainage was performed in 12 (57%). Fifteen patients (71%) were supported by IABP postoperatively, and re-rupture occurred in 3 patients without IABP. Long-term outcomes were significantly better in the sealed type than in the BO type. CONCLUSION: Sixty percent of postinfarction ventricular free wall rupture was the sealed type. Median sternotomy and sutureless repair with postoperative IABP support were reliable treatments. Subxiphoid drainage and strict blood pressure control with IABP may be acceptable surgical strategies in elderly, frail patients.

The Systemic Inflammation Score Is an Independent Prognostic Factor for Esophageal Cancer Patients who Receive Curative Treatment.

BACKGROUND/AIM: Perioperative systemic inflammation affects the long-term oncological outcomes in cases of malignancies. We evaluated the clinical impact of the preoperative systemic inflammation score (SIS) in resectable esophageal cancer patients who received curative treatment. PATIENTS AND METHODS: This study included 168 patients who underwent curative surgery followed by perioperative adjuvant chemotherapy for esophageal cancer between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rate, we set the cut-off value for SIS at 2 in the preset study. Among the 168 total patients, 119 were categorized as the Low-SIS group, and 49 were categorized as the High-SIS group. The respective 3- and 5-year OS rates were 61.9% and 52.4% in the Low-SIS group and 33.3% and 26.6% in the High-SIS group. There were significant differences in OS (p<0.001). The SIS was therefore selected for the final multivariate analysis model (hazard ratio=2.094, 95% confidence interval=1.355-3.234, p<0.001). On comparing the perioperative clinical course between the High- and Low-SIS groups, there were significant differences in the rate of postoperative anastomosis leakage of grade ≥2 between the groups (61.5% in the High-SIS group vs. 30.3% in the Low-SIS group; p=0.021). CONCLUSION: The systemic inflammation score had a clinical effect on the long-term oncological outcomes in esophageal cancer patients, suggesting that it might be a promising prognostic factor for esophageal cancer patients.

Clinical Impact of Preoperative Albumin-Bilirubin Status in Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin-bilirubin (ALBI) score, which evaluates the perioperative liver function, was developed, and had a clinical impact on both the short- and long-term oncological outcomes in some malignancies. We evaluated the clinical impact of preoperative albumin-bilirubin status in patients with resectable esophageal cancer who received curative treatment. PATIENTS AND METHODS: The study included 121 patients who underwent curative surgery followed by adjuvant chemotherapy for esophageal cancer between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rates, we set the cut-off value for the ALBI score at -2.7. Eighty patients were classified into the ALBI-low group (ALBI score <-2.7), 41 patients were categorized into the ALBI-high group (ALBI score >-2.7). The 3- and 5-year OS rates were 62.2% and 53.2%, respectively, in the ALBI-low group, and 42.2% and 35.2% in the ALBI-high group. There was a significant difference in OS (p=0.0113). The 3- and 5-year RFS rates were 43.1% and 40.3%, respectively, in the ALBI-low group and 37.7% and 26.1% in the ALBI-high group. There was a significant difference in RFS (p=0.048). When comparing the perioperative clinical course between the ALBI-high and ALBI-low groups, the incidence of postoperative anastomotic leakage was 46.3% (19/41) in the ALBI-high group, and 27.5% (22/80) in the ALBI-low group (p=0.038). CONCLUSION: The ALBI status had a clinical impact on both OS and RFS in esophageal cancer patients. Therefore, ALBI may have potential application as a prognostic factor for esophageal cancer patients.

Rapid anticalcification treatment for glutaraldehyde-fixed autologous tissue in cardiovascular surgery.

BACKGROUND: Glutaraldehyde (GA)-fixed autologous tissues, including the pericardium, are widely used as patches and valve substitutes in cardiovascular surgery. However, GA treatment causes tissue calcification. No rapid anticalcification method has been established for use during surgery. Here, we aimed to establish a rapid anticalcification method using ethanol, as has already been demonstrated for bioprosthetic valves. METHODS: Thoracic aorta tissues were first fixed with GA for 3 min and then treated with ethanol for 0 (group 2), 10 (group 3), 20 (group 4), and 30 (group 5) min; untreated tissues (group 1) served as the control. The treated tissues were subdermally implanted into 3-week-old male Wistar rats and kept in place for 28 days. The calcification in each explant was semiquantitatively evaluated by annotating and measuring the area using virtual slides, and the data obtained were statistically analyzed. RESULTS: Semiquantitative analysis revealed that calcification of the implants from the untreated group (group 1; P = 0.0014) and groups 4 (P = 0.0014) and 5 (P = 0.0031) was significantly lower than that of implants from group 2. Moreover, implants from group 3 showed a tendency toward decreased calcification, although it was not significant (P = 0.0503). CONCLUSIONS: A rapid ethanol treatment prevents calcification of GA-fixed tissues in a rat model of subdermal implantation. This method may facilitate effective and rapid anticalcification of autologous tissues for use during cardiovascular surgery.
