A 49-year-old female with ruptured left common iliac mycotic arterial aneurysm (Lt. CIAA) was brought to our hospital as an emergency case. In Japan, endovascular treatment is unsuitable for the treatment of mycotic aneurysms, but findings from a Swedish national database showed that there was no difference in the long-term prognosis lasting over 10 years. Therefore, we performed endovascular aortic repair (EVAR) and saved the patient's life. The diameter of the proxymal sealing zone was larger than that of the distal zone. We used the Gore Excluder leg, which was inverted and implanted to match the caliber. Percutaneous abscess drainage was also performed on postoperative day 7 when hemostasis was confirmed for early infection control. The patient was discharged at 8 weeks postoperatively. After discharge from the hospital, oral antibiotics were continued until 6 months after the surgery. Six months postoperatively, contrast-enhanced computed tomography showed that the abscesses have disappeared. Blood samples that were taken at one month after the completion of antibiotics showed no evidence of the recurrence of infection and a curative course was achieved.

Background: and Purpose The objective of this study was to identify 2-year longitudinal changes in the muscle thickness (MT) and echo intensity (EI) of the abdominal, thigh, and lower limb muscles in chronic stroke survivors. Methods: This study included 15 chronic stroke survivors aged 74.1±9.9 years. The MT, EI, and subcutaneous fat thickness values of the following muscles on the paretic and nonparetic sides were assessed on transverse ultrasound images: rectus abdominis, external oblique, internal oblique, transversus abdominis, rectus femoris (RF), vastus intermedius, vastus lateralis (VL), vastus medialis, tibialis anterior, gastrocnemius, and soleus. The ultrasound measurements were performed both at baseline and 2 years later. Results: After 2 years, the VL on the paretic side showed a significant decrease in MT (p= 0.031) and increase in EI (p=0.002), whereas the RF on the nonparetic side showed a significant decrease in EI (p=0.046). Correlation coefficient analyses showed that changes in MT (r= 0.668, p=0.012) and EI (r=0.597, p=0.018) of the VL on the paretic side were significantly associated with a change in the body mass index. Conclusions The findings of this longitudinal study suggest that the VL on the paretic side is subject to deteriorations in muscle quantity and quality, and conversely that the RF on the nonparetic side shows an improvement in muscle quality after 2 years in chronic stroke survivors

BACKGROUND: Remnant-like particle cholesterol (RLP-C) is highly atherogenic, which is associated with atherosclerosis. However, RLP-C has not been routinely measured in the clinical practice. We estimated RLP-C levels using conventional lipid profiles and examined the association between estimated RLP-C and related factors including nutrient intake. METHODS: This study was performed in Uku town, Nagasaki prefecture, Japan in 2019. A total of 225 subjects were enrolled and directly measured RLP-C levels. Estimated RLP-C levels were defined as the following formula [total cholesterol - (LDL-cholesterol) - (HDL-cholesterol)]. Multivariate analyses were used to assess the relationship between estimated RLP-C and atherogenic factors. We calculated cut-off values on dichotomized RLP-C (< 7.5 mg/dL vs. ≥ 7.5 mg/dL) by receiver operating characteristic (ROC) curve. RESULTS: The mean values of directly measured RLP-C levels and estimated RLP-C were 4.0 mg/dL and 16.4 mg/dL, respectively. In the multiple stepwise linear regression analysis, directly measured and estimated RLP-C levels were independently and commonly associated with apolipoprotein E, triglycerides, and vegetable fat intake (inversely). Using ROC curves, we found the cut-off value of estimated RLP-C was 22.0 mg/dL. CONCLUSION We demonstrated that the estimated RLP-C levels using conventional lipid profiles may substitute for directly measured RLP-C and these levels were independently and inversely associated with vegetable fat intake in the community-dwelling Japanese population.

BACKGROUND: There is little data on the association between the lower nutrition represented by serum albumin levels and related factors in a general population. The present study aimed to determine whether the albumin level positioned as some kind of biomarker with frailty measures, trace elements, and an inflammation marker. METHODS: In 2018, we performed an epidemiological survey in 1368 subjects who resided in Tanushimaru, Japan, in which we examined the blood chemistry including albumin, trace elements, hormone levels, and carotid ultrasonography. Albumin levels were categorized into 4 groups (G1 [3.2-3.9 mg/dL], G2 [4.0-4.3 mg/dL], G3 [4.4-4.6 mg/dL], and G4 [4.7-5.3 mg/dL]). The participants underwent measurements of handgrip strength and were tested by asking to walk 5 m. Their cognitive functions were evaluated by the mini-mental state examination (MMSE). RESULTS: Multiple stepwise regression analysis demonstrated that albumin levels were significantly and independently associated with age (inversely), systolic blood pressures, estimated glomerular filtration rate (eGFR), MMSE score, frailty measures (handgrip strength), an inflammation marker (high-sensitivity C-reactive protein), hormones (growth hormone (inversely) and insulin-like growth factor-1), and trace elements (calcium, magnesium, iron, and zinc), with a linear trend. CONCLUSIONS Lower albumin levels, even in the normal range, were found to be related factors of frailty measures, trace elements, and an inflammation marker in a general population.

Cardiac leiomyosarcoma and atrial intramural hematoma are extremely rare. Here, we present the case of a 52-year-old woman with dyspnea. Echocardiography showed a large mass in the left atrium. Tumor resection was performed. A pathological diagnosis of intramural hematoma was made. Ten months later, she presented to our hospital again with dyspnea. Echocardiography and computed tomography showed recurrence of the left atrial tumor. Another tumor resection operation was performed. The tumor originated from the inferior wall of the left atrium, and it was surrounded by atrial wall thickening. Complete resection was not possible. Although postoperative chemotherapy was prescribed, the patient died of heart failure nine months after the second operation.

BACKGROUND AND PURPOSE: This study compared the muscle thickness (MT) and echo intensity (EI) of the abdominal, thigh, and lower leg muscles between the paretic and nonparetic sides in chronic stroke survivors. METHODS: Thirty-two stroke survivors living in the community participated in this study. The MT and EI, which are indicators of muscle mass and intramuscular fat or connective tissue, were assessed in the rectus abdominis, external oblique, internal oblique, transversus abdominis, rectus femoris, vastus intermedius, vastus lateralis, vastus medialis, tibialis anterior, gastrocnemius, and soleus via transverse ultrasound imaging. In addition, a possible indicator of physical activity—the frequency of going out per week—was evaluated. RESULTS: All quadriceps muscles and the tibialis anterior were significantly thinner and the EI values of the vastus intermedius, vastus lateralis, vastus medialis, and soleus were significantly higher in the paretic limb than the nonparetic limb. The MT and EI values of abdominal muscles did not differ significantly between the two sides. The MT values of the paretic rectus femoris, vastus lateralis, and vastus medialis were significantly associated with the frequency of going out after adjusting confounding factors. The MT of the nonparetic vastus lateralis was significantly associated with latency from stroke onset after adjusting confounding factors. CONCLUSIONS: Our results indicate that quantitative and qualitative changes on the paretic side in stroke survivors were the most robust in the thigh muscles, whereas such changes might not occur in the abdominal muscles.

We report 4 cases of aortic graft replacement for Kommerell diverticulum (KD) and the aberrant subclavian artery (ASA). In two patients who had a right-sided aortic arch, KD and the left ASA, we performed descending aorta replacement and in-situ reconstruction of the left ASA via a right lateral thoracotomy. Third patient had a left-sided aortic arch, KD and the right ASA, in whom we performed descending aorta graft replacement via a left lateral thoracotomy with ostial closure of the right ASA. Fourth patient had a left-sided aortic arch, KD and the right ASA, and complicated by acute type A aortic dissection. We performed a total arch repair with frozen elephant trunk procedure via a median sternotomy. All 4 patients survived operations and discharged from the hospital with symptom relief. The choice of approach, a thoracotomy or a median sternotomy, should be based on patient-specific anatomy and extent of graft replacement.

We present herein a case of disc fracture of a Björk-Shiley valve prosthesis in the mitral position. A 69-year-old woman was admitted to our hospital with a sudden onset of dyspnea followed by deep shock. An echocardiography showed a severe degree of mitral regurgitation and moderate degree of tricuspid regurgitation. Forty-three years previously she had undergone a mitral valve replacement (MVR) for stenosis with the original version of a Björk-Shiley valve prosthesis in another institute. Emergency redo MVR was performed with a bioprosthesis and tricuspid annuloplasty with a semirigid ring. The disc of the extracted Björk-Shiley valve was found to have escaped from the metal housing with two intact struts. Although Björk-Shiley valve dysfunction due to Delrin disk abration has been rarely reported, complete disk fracuture is extremely rare. The important role of regular echocardiographic follow-up should be emphasized to prevent fatal valve fracture.
