A 27-year-old woman developed circulatory failure 4 days after birth and was diagnosed with mid-aortic syndrome (MAS) 10 days after birth. Despite repeated endovascular treatments, restenosis recurred, and descending aorta-abdominal aorta bypass surgery was performed at the age of 6. Since the age of 14, bilateral external iliac artery occlusion has been observed, but no ischemic symptoms were observed in the lower extremities, and the patient was followed up. From around the age of 26, significant claudication appeared in both lower extremities, and it was determined that surgical intervention was required. Bilateral common iliac artery-common femoral artery bypass surgery was performed. The bilateral common iliac arteries were used as the central anastomosis, and the common femoral artery just above the bifurcation of the bilateral superficial and deep femoral arteries was used as the peripheral anastomosis. No ischemic symptoms in the lower extremities have been observed up to now (2 years after the operation). Bilateral common iliac artery-common femoral artery bypass surgery was performed for abdominal aortic stenosis with hypoplasia of the bilateral external iliac arteries and lower extremity artery disease (LEAD). Since we experienced the case with favorable results, we will add a review of the literature and report it.

Three-dimensional (3D) cultures are known to promote cell differentiation. Previously, we investigated the differentiation of rat dermal fibroblasts to α-smooth muscle actin (α-SMA)-positive myofibroblasts through transforming growth factor (TGF)-β production using a 3D culture model. Here, we investigated the phenotypic change from dermal mesenchymal cells (mostly fibroblasts) to osteoblast-like cells, being inspired by the roles of smooth muscle cells or fibroblasts during vascular calcification. Spindle-shaped cells that grew in heterologous populations out of dermal explants from 2-day-old Wistar rats were cultured within a collagen matrix. α-SMA and alkaline phosphatase (ALP) messenger RNA (mRNA) levels initially increased, followed by a rise in Runx2 and osteocalcin (OCN) mRNA levels without calcification. Calcium deposits were produced in the presence of a high concentration of inorganic phosphate (2.1 mM) or β-glycerophosphate (βGP, 10 mM) after 2 weeks of culture, and both were sensitive to an inhibitor of type III phosphate transporters. An ALP inhibitor decreased only βGP-induced calcification. Inhibition of TGF-β type-I receptors attenuated ALP mRNA levels and βGP-induced calcification, suggesting that endogenous TGF-β stimulates ALP activity and then βGP breakdown. An increase in the number of cells embedded in the collagen gel enhanced the mRNA levels of Runx2 and OCN, but not of ALP. Collectively, several factors are likely to promote the differentiation of dermal mesenchymal cells into osteoblast-like cells and ectopic calcification in a 3D collagen matrix, implying the utility of these cells as a potential autologous cell source for tissue engineering.

Methods:
The outcomes of 72 patients who underwent BKP for VCFs between 2015 and 2021 were retrospectively investigated. Patients with DISH were assigned to group D (n=21), whereas those without DISH were assigned to group ND (n=51). Back pain, incidence of subsequent adjacent fractures, reoperation rates, and local kyphosis were statistically analyzed.
Results:
VCFs in group D occurred at the distal end or adjacent vertebra of the fused segments, and no fractures occurred in the midportion of the fused segment. Back pain improved in both groups, with no significant differences between them. Subsequent adjacent fractures were observed in three of the 21 patients in group D and 11 of the 51 patients in group ND, with no significant difference between them. Reoperation was performed in one patient each in groups D and ND, with no significant difference between the groups. Postoperatively, local kyphosis progressed significantly in group D.
Conclusions
Although local kyphosis is more advanced in patients with DISH, BKP is effective for VCFs at the distal end or adjacent vertebra of the fused segments and may be useful in older patients with high complication rates.

Asian Spine Journal 2023;17(5):818-825
Methods:
The medical records of patients with intervertebral TLIF from 2012 to 2018 were retrospectively examined. The patients were divided into those with fusion and those with pseudoarthrosis, and the following data were compared: age, sex, DISH, diabetes mellitus, smoking, drinking, albumin levels, body mass index ≥30 kg/m2, and L5/S fixation. Statistical analyses were performed using regression models.
Results:
In this study, 180 patients (78.6%) had fusion and 49 patients (21.4%) had pseudoarthrosis. The number of patients with DISH was significantly higher in the pseudoarthrosis group than in the fusion group (36.7% and 21.7%, respectively; univariate p=0.031, multivariate p =0.019). No significant differences in age, sex, diabetes mellitus, smoking, drinking, albumin levels, body mass index ≥30 kg/m2, and L5/S fixation were observed between the two groups. The risk factors for bone fusion were statistically analyzed in 57 patients with DISH. DISH with a caudal end below Th11 was an independent risk factor for pseudoarthrosis (univariate p=0.011, multivariate p=0.033).
Conclusions
DISH is an independent risk factor for pseudoarthrosis after one intervertebral TLIF, and DISH with a caudal end below Th11 is associated with a higher risk of pseudoarthrosis than DISH without a caudal end below Th11.

BACKGROUND:
Epidemiological evidence has shown that serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations, a diagnostic biomarker for heart failure, are positively associated with cardiovascular risk. Since NT-proBNP in serum is excreted in urine, it is hypothesized that urinary NT-proBNP concentrations are correlated with serum concentrations and linked with cardiovascular risk in the general population.
METHODS:
A total of 3060 community-dwelling residents aged ≥ 40 years without history of cardiovascular disease (CVD) were followed up for a median of 8.3 years (2007-2015). Serum and urinary concentrations of NT-proBNP at baseline were compared. The hazard ratios (HRs) and their 95% confidence intervals (CIs) for the association between NT-proBNP concentrations and the risk of developing CVD were computed using the Cox proportional hazards model.
RESULTS:
The median values (interquartile ranges) of serum and urinary NT-proBNP concentrations at baseline were 56 (32-104) pg/mL and 20 (18-25) pg/mL, respectively. There was a strong quadratic correlation between the serum and urinary concentrations of NT-proBNP (coefficient of determination [R
CONCLUSIONS
The present study demonstrated that urinary NT-proBNP concentrations were well-correlated with serum concentrations and were positively associated with cardiovascular risk. Given that urine sampling is noninvasive and does not require specially trained personnel, urinary NT-proBNP concentrations have the potential to be an easy and useful biomarker for detecting people at higher cardiovascular risk.

Ependymomas are uncommon tumors that arise in the brain, spinal cord or cauda equina. Myxopapillary ependymomas is located exclusively in the conus medullaris or cauda equina, or film terminale region. In most myxopapillary ependymomas, the histological examination reveals low mitotic activity that is associated with a low MIB-1 labeling index (LI). The prognosis is generally favorable, when the appropriate treatment, including a total resection, is performed. The authors encountered a 39-year-old man with multifocal type of myxopapillary ependymomas compressing the cauda equina from the L2 to L3 level and L5-S1 level. A subtotal resection of the tumor was carried out. The histological examination revealed extremely high mitotic activity with a MIB-1 LI of 9.1%. Therefore, cranio-spinal radiation was added after surgery. The postoperative course was uneventful over the 3.5 year follow-up period.

This study aimed to explore the association between various levels of training-energy expenditure (TrEE) and nutritional response during the phases of periodization among male collegiate rugby players. Seventeen Japanese male collegiate rugby players were enrolled in the study. Their TrEE and dietary intake were assessed each day during three separate microcycle training phases in the preparatory phase of periodization (P1 and P2: general training phase consisting of two sessions per day over the term during which the school held classes and during a summer vacation, respectively; and P3: intensive training phase consisting of four sessions per day during a summer vacation) using the factorial method and dietary records, respectively. The TrEE for P3 (1644±273 kcal) was significantly higher than that for P1 (891±230 kcal). However, the total energy intake (EI) for P3 (3274±889 kcal) was significantly lower than that for P1 (3978±938 kcal). The daytime (after waking in the morning and before the evening training session) EI (242±159 kcal) and protein intake (19±12 g) from the ‘high-protein foods group’ during P3 was significantly reduced compared with that during P1 (465±252 kcal, 37±15 g), whereas, EI and carbohydrate intake from the ‘supplements group’ of P3 was significantly increased compared with P1. The increased TrEE during P3 was not compensated by EI; instead, there was a decreased nutrient intake from the high-protein foods group and increased intake from the supplements group. The time of day of multiple or intensive training sessions, i.e. different TrEE, might affect the food choices made by male rugby players.

OBJECTIVE: Electroconvulsive therapy (ECT) has proven to be effective in treatment-resistant depression (TRD). In recent reports, 70% to 90% of patients with TRD responded to ECT. However, post-ECT relapse is a significant problem. There are no studies investigating risk factors associated with reintroducing ECT in depressive patients after remission previously achieved with former ECT. The aim of the present study is to examine such risk factors using a sample of TRD patients. METHODS: We conducted a chart review to examine patient outcomes and adverse events over short- and long-term periods. Forty-two patients met the criteria for major depressive disorder. RESULTS: The response rate was 85.7% (36/42). There were no significant differences in the baseline characteristics of patients exhibiting remission, response or non-response. The rate of adverse events was 21.4% (9/42). Among 34 patients who were available for follow-up, 18 patients relapsed (relapse rate, 52.9%), and 6 patients were reintroduced to ECT. The patients' age and age of onset were significantly higher in the re-ECT group than non re-ECT group. CONCLUSION: Our results suggest that older age and older age of onset might be considered for requirement of re-ECT after remission previously achieved with former ECT.

BACKGROUND/AIMS: Helicobacter pylori infection causes gastritis, peptic ulcers and gastric malignancies, and its eradication has been advocated by many groups. We determined the H. pylori carrier status and eradication rates of patients with chronic hepatitis C virus (HCV) infection. METHODS: In total, 76 chronically HCV-infected patients were enrolled for comparison with 228 HCV-noninfected, age- and sex-matched controls. H. pylori infection was confirmed by H. pylori antibody and urea breath testing. RESULTS: The H. pylori infection rate was significantly higher for HCV-infected patients (67 of 76, 88.2%) than for HCV-noninfected controls (158 of 228, 69.3%). Endoscopic findings showed that the rates of gastric ulcers and gastritis were significantly higher for the 67 HCV-infected patients with H. pylori infection (34.3% and 77.6%) than for the 158 HCV-noninfected controls with H. pylori infection (15.2% and 57.6%). Treatment to eradicate H. pylori had a significantly higher success rate for HCV-infected patients (61 of 67, 91.0%) than for HCV-noninfected controls (115 of 158, 72.8%). CONCLUSIONS: The markedly high H. pylori eradication rate observed in this study shows that eradication of H. pylori holds promise for the improvement of the long-term health condition of patients with chronic HCV infection.
