Abstract
BACKGROUND Physiological dysregulation/allostatic load and the geriatric syndrome frailty increase with age. As a neurophysiological response system, allostasis supports survival by limiting stressor-related damage. Frailty reflects decreased strength, endurance, and physical abilities secondary to losses of muscle and bone with age. One suggestion, based on large cohort studies of person's ages 70 + years, is that frailty contributes to allostatic load at older ages. However, small community-based research has not confirmed this specific association. METHODS To further explore possible associations between allostatic load and frailty, we enrolled 211 residents of Greater Poland aged 55-91 years living in a small village (Nekla, N = 104) and an urban center and capital of Greater Poland (Poznan, N = 107). For each, we recorded age, self-reported sex, and residence and estimated a 10-biomarker allostatic load score (ALS) and an 8-biomarker frailty index. We anticipated the following: higher ALS and frailty among men and rural residents; for frailty but not ALS to be higher at older ages; significant associations of ALS with sex and place of residence, but not with age or frailty. The significance of observed associations was evaluated by t-tests and multivariate regression. RESULTS ALS did not vary significantly between men and women nor between Nekla and Poznan residents overall. However, women showed significantly higher frailty than men. Nekla men showed significantly higher ALS but not frailty, while Nekla women showed nonsignificantly higher ALS and lower frailty than Poznan. In multivariate analyses, neither age, nor sex, nor residence was associated with ALS. Conversely, age, sex, and residence, but not ALS, are associated significantly with frailty. In Nekla, both age and sex, but in Poznan only age, are associated with ALS. Among women, both age and residence, but among men, neither associated with ALS. In no case did ALS associate significantly with frailty. CONCLUSION In this sample, lifestyle factors associated with residence, age, and sex influence stress-related physiology, less so in women, while ALS and frailty do not covary, suggesting their underlying promoters are distinct. Similar complex associations of physiological dysregulation with frailty, age, sex, and residence likely exist within many local settings. Knowledge of this variation likely will aid in supporting health and healthcare services among seniors.

Abstract
An 84-year-old male with a medical history notable for prior thoracic endovascular aortic repair for thoracic aneurysm nine years ago presented to the emergency department with a chief complaint of transient loss of consciousness. A brain computed tomography showed no remarkable findings. A subsequent computed tomography scan for comprehensive evaluation revealed DeBakey type II acute aortic dissection as evidenced by contrast-enhanced imaging. An intimal tear was found on the ascending aorta distant from the proximal edge of a stent graft. Due to the urgency of the situation, the patient underwent emergent ascending aortic replacement. Following the successful intervention, the patient was transferred to a specialized rehabilitation facility with the goal of facilitating further improvement in their condition.

Abstract
Herein, we present a case of aortic dissection with right carotid artery occlusion that was treated successfully with thrombus evacuation from the false lumen of the occluded carotid artery during hemiarch replacement. This procedure is performed with two maneuvers: aggressive retrieval of the thrombus from the innominate artery during circulatory arrest and thrombus evacuation from the false lumen of the right common carotid artery through a right neck incision with the heart beating. In this alternative method, thrombi can be evacuated more naturally and briskly, using pulsatile flow.

Abstract
Herein, we present the case of an 89-year-old female who presented with acute aortic dissection involving the arch and abdominal aneurysms. Emergent total arch replacement with a frozen elephant trunk was the first-line approach taken to save the patient's life. Although prolonged mechanical ventilation necessitated a tracheostomy, subsequent endovascular aortic repair mitigated the risk of rupture in the abdominal aortic aneurysm. While managing acute aortic syndrome with multiple aneurysms poses a challenge for surgeons, a diagnosis based on computed tomography angiography and timely intervention alleviated the critical condition.

Abstract
An incidental discovery was made of a right deep femoral artery aneurysm (DFAA) in a plain computed tomography (CT) scan of a 72-year-old male. Although he had been diagnosed with type B aortic dissection six years ago and was followed for 12 months in the outpatient clinic, the patient was no longer receiving regular checkups. After a thorough discussion between cardiovascular surgeons and interventional radiologists, it was decided to proceed with aneurysm resection and revascularization. The postoperative course was uneventful, and the patient was discharged home without complications.

Abstract
Infected thoracic aneurysms are a rare and potentially life-threatening condition that present with non-specific symptoms. We describe here a case of an 83-year-old female who presented to the emergency department with the chief complaint of vomiting blood. The patient had presented to the emergency department 40 days earlier with abdominal pain, fever, and leukocytosis. She had a medical history of traumatic liver injury resulting in bile duct stenosis, necessitating percutaneous transhepatic gallbladder drainage and subsequent bile duct-jejunal anastomosis 25 years ago. Emergency contrast-enhanced computed tomography (CT) revealed an irregular distal arch aneurysm. According to the patient's present symptoms, CT findings, and medical history, infected thoracic aneurysm was suspected. Total arch replacement was performed promptly, followed by thorough antibiotic therapy. Following successful treatment, the patient's condition stabilized, and she was transferred to a rehabilitation facility for further recovery.

Abstract
A 59-year-old male was transported to the emergency department by ambulance with complaints of left-sided abdominal pain. Blood gas analysis revealed elevated lactate, and plain computed tomography revealed no bowel ischemic change. Contrast-enhanced computed tomography revealed isolated superior mesenteric artery dissection with mildly stenosed true lumen. The patient was treated with conservative management on admission. Staged fluid intake, oral prescriptions, and diet were commenced with attention to the symptoms. After four days of hospitalization, the patient was discharged with a stable condition. However, the patient returned to our hospital complaining of left lower back pain three hours after discharge. Contrast-enhanced computed tomography revealed an enlarged false lumen with a moderately stenosed true lumen. After a thorough discussion between vascular surgeons and interventional radiologists, conservative management was commenced on the second admission. The clinical course was uneventful, with proof of improved imaging findings.

Abstract
A 59-year-old male presented to the emergency department with distressing epigastric pain after seeking medical attention at a nearby clinic three hours prior. Upon examination, the attending physician noticed edematous changes in the proximal segment of the superior mesenteric artery, and a subsequent enhanced computed tomography (CT) scan confirmed the diagnosis of an isolated dissection of the artery. Notably, the true lumen of the vessel was significantly narrowed, raising concerns for potential vascular compromise. After extensive consultation between a vascular surgeon and a radiologist, a decision was made to adopt a conservative management approach. The patient was closely monitored with meticulous bowel rest, hydration management, and carefully curated dietary modifications. Over time, subsequent CT scans revealed progressive enlargement of the true lumen, which was highly reassuring to the medical team. As a result of the expert management and diligent care provided, the patient was eventually discharged home without any adverse events or complications. This case highlights the critical role of a multidisciplinary approach in managing complex vascular pathology and underscores the importance of thoughtful clinical decision-making and meticulous monitoring in achieving favorable outcomes.

Abstract
A 64-year-old man on dialysis presented to the emergency department with a fever and chills. Transthoracic echocardiography (TTE) showed small vegetation on the posterior mitral leaflet (PML). Antibiotic therapy was initiated. Two weeks later, right hemiparesis occurred. MRI of the head showed occlusion of the left middle cerebral artery, which suggested an embolism derived from the vegetation. The patient was then referred to the department of cardiovascular surgery. Transesophageal echocardiography (TEE) revealed perforation of the PML and severe mitral regurgitation (MR). The patient underwent mitral valve repair. The postoperative course was uneventful, and the patient was discharged after six weeks of antibiotic treatment. A fresh autologous pericardium is the material of choice to repair the valve.

Abstract
BACKGROUND Whether direct-acting anti-viral therapy can reduce liver fibrosis and steatosis in patients with chronic hepatitis C virus (HCV) infection is unclear. AIMS To evaluate changes in liver stiffness and steatosis in patients with HCV who received direct-acting anti-viral therapy and achieved sustained virological response (SVR). METHODS A total of 198 patients infected with HCV genotype 1 or 2 who achieved SVR after direct-acting anti-viral therapy were analysed. Liver stiffness as evaluated by magnetic resonance elastography, steatosis as evaluated by magnetic resonance imaging-determined proton density fat fraction (PDFF), insulin resistance, and laboratory data were assessed before treatment (baseline) and at 24 weeks after the end of treatment (SVR24). RESULTS Alanine aminotransferase and homeostatic model assessment-insulin resistance levels decreased significantly from baseline to SVR24. Conversely, platelet count, which is inversely associated with liver fibrosis, increased significantly from baseline to SVR24. In patients with high triglyceride levels (≥150 mg/dL), triglyceride levels significantly decreased from baseline to SVR24 (P = 0.004). The median (interquartile range) liver stiffness values at baseline and SVR24 were 3.10 (2.70-4.18) kPa and 2.80 (2.40-3.77) kPa respectively (P < 0.001). The PDFF values at baseline and SVR 24 were 2.4 (1.7-3.4)% and 1.9 (1.3-2.8)% respectively (P < 0.001). In addition, 68% (19/28) of patients with fatty liver at baseline (PDFF ≥5.2%; n = 28) no longer had fatty liver (PDFF <5.2%) at SVR24. CONCLUSION Viral eradication reduces both liver stiffness and steatosis in patients with chronic HCV who received direct-acting anti-viral therapy (UMIN000017020).

Abstract
Background It is very important for the late-stage elderly to have the least stressful bowel movements for maintaining a good quality of life. It is generally accepted that consuming adequate dietary fiber is a promising method for the prevention and management of stressful bowel movements such as those during constipation. Therefore, we examined the effect of long-term consumption of waxy barley, which is high in dietary fiber, on the bowel movements of the late-stage elderly living at Roken nursing home (a geriatric health services facility), Japan. Methods We compared the defecation and laxative administration frequencies of the subjects before and after waxy barley consumption, for which we served 28 residents a boiled mixture of rice and waxy barley (variety name, Kirarimochi) as the main meals for 5 months, from November to March. In October, all residents were served boiled rice as the main meals. Results The residents were categorized into “constipated” subjects and “non-constipated” subjects according to their weekly defecation frequency during October. Among the 14 residents categorized as constipated subjects, monthly number of days with defecation in November, January, and March significantly increased in comparison to monthly number of days with defecation in October. In addition, monthly number of days with laxative administration significantly decreased in December and February in comparison to monthly number of days with laxative administration in October. In contrast, the defecation and laxative administration frequencies did not change after waxy barley consumption among the 14 residents categorized as non-constipated subjects. Conclusions Consumption of waxy barley, Kirarimochi, for 5 months improved the bowel movements of the constipated subjects; however, the consumption had no effect on the bowel movements of the non-constipated subjects at Roken nursing home. These results indicate that consuming waxy barley, Kirarimochi, is beneficial for the management of constipation in the late-stage elderly residents at Roken nursing home.

Abstract
BACKGROUND Lifelong exposure to stressors promotes physiological dysregulation and produces an allostatic load (AL). In European-derived samples, AL associates significantly with sex, age and health. AIM To assess associations of AL with age, sex, socio-demographic differences and self-reports of diet and ability to complete activities of daily living in older Japanese residing in rural Nagasaki Prefecture. SUBJECTS AND METHODS In 2011, 96 older residents of Nagasaki Prefecture, Japan, were assessed for components of AL. They also self-reported their age, principal life-long occupational activity, educational attainments, marital status, dietary choices and abilities to complete daily living activities. RESULTS Average age was 67.9 years (range = 55-89; SD = 8.65). Among these 48 men and 48 women, AL was not related significantly to age, although women showed lower AL than men. AL did not differ significantly between respondents by occupation, marital status, education or abilities to complete daily activities. Women who reported eating more green/yellow vegetables or consuming more meat had lower AL than their counterparts. Men who reported drinking more alcohol spirits had higher AL. CONCLUSIONS Among older Japanese residing outside a major urban area, AL varies significantly by sex, but not age, while being associated with dietary choices. Although lack of association with life ways was not expected, AL apparently assesses physiological dysregulation cross-culturally.

Abstract
OBJECTIVE To determine the prevalence and clinical features of pathologically proven incidental cancer (IC) detected by whole-body fluorine-18 fludeoxyglucose ((18)F-FDG) positron emission tomography (PET)/CT, as well as the incidence of false-positive and false-negative results. METHODS We retrospectively reviewed reports derived from (18)F-FDG PET/CT images of 3079 consecutive patients with known or suspected malignancies for 3 years. Discrete focal uptake indicating IC was identified from reports as well as pathological or clinical diagnoses, and the clinical courses were investigated. The false-positive result was defined as uptake indicating IC but not pathologically confirmed as malignant during follow-up. The false-negative result was defined as pathologically proven IC detected by another modality at initial clinical work-up or diagnosed during the follow-up period. RESULTS We found (18)F-FDG uptake indicating IC in 6.7% of all patients, and IC was pathologically proven in 2.2% of all patients. The most common sites were the colon, lung and stomach. The median survival duration of patients with IC was 42 months. The results were false positive in 4.5% of all patients, and the results were false negative in 2.3% of all patients. CONCLUSION (18)F-FDG PET/CT is a valuable tool for detecting IC. The rates of false-positive and false-negative results are within acceptable range. ADVANCES IN KNOWLEDGE This is the first report to describe the survival of patients with IC, and the detailed features of false-negative results at actual clinical settings.

Abstract
Listeria monocytogenes is a foodborne pathogen that causes the potentially life-threatening illness listeriosis. Previously, a few clones of L. monocytogenes persisting in a cold-smoked fish processing plant were isolated from the plant's products continuously. To evaluate the role of biofilms in the persistence of L. monocytogenes strains specific to this plant, the abilities of the persistent strain (PS) and transient strain (TS) of L. monocytogenes found in this plant to form biofilms were compared, as was resistance to the sanitizing effects of benzalkonium chloride (BC). The PS produced more biofilm than the TS in 48 h. The half-maximal effective concentration (EC50), the BC concentration at which the ATP bioluminescence of each bacterial strain decreased by 50 % relative to its maximum activity, was about 150-fold higher in the PS than in the TS. In contrast, when these values were measured in organisms in a planktonic state, the EC50 of the PS was only 2.2-fold higher than that of the TS. Extracellular polymeric substances (EPS) were extracted from biofilms, and the glucose content of these biofilms was determined with the phenol-sulfuric acid method to estimate the quantity of EPS. The total amount of EPS in the PS biofilm was higher than that in the TS biofilm. These findings suggest that the PS produces greater amounts of biofilm and EPS than the TS, which results in greater resistance of the PS to disinfectants. The persistence of the strain in the fish processing plant might be attributable to these properties.
