Objective:
Sitosterolemia is a rare autosomal recessive disease caused by the deleterious variants of adenosine 5'-triphosphate (ATP)-binding cassette sub-family G member 5 (ABCG5) or ATP-binding cassette sub-family G member 8 (ABCG8). There are only few data on the pathogenicity of ABCG5 and ABCG8. This study aimed to propose a scheme for determining variant pathogenicity and to catalog the putative pathogenic variants in sitosterolemia.
Methods:
This study enrolled 377 consecutive Japanese patients with hyper-low-density lipoprotein cholesterolemia (mean age: 46.5±19.8 years, with 192 men) who have targetedsequenced data on ABCG5 or ABCG8 (among 21 Mendelian lipid genes for any dyslipidemias) and serum sitosterol levels at Kanazawa University Hospital from 2016 to 2021. Serum sitosterol levels were divided by 0.79 in patients treated with ezetimibe, accounting for the average reduction with this drug. ABCG5 or ABCG8 variants were defined as putative pathogenic if associated with serum sitosterol levels ≥5 µg/mL or homozygous if associated with serum sitosterol levels ≥10 µg/mL.
Results:
Twenty-three ABCG5 or ABCG8 variants (16 missense, 2 nonsense, 2 frameshift, 2 deletion, and 1 splice mutation) were identified. Based on our definition, 11 putative pathogenic variants (median sitosterol level: 10.1 [6.5–17.1] µg/mL) were found in 36 individuals and 12 benign variants (median sitosterol: 3.5 [2.5–4.1] µg/mL) in 14 individuals.
Conclusion
The scheme proposed for assessing the pathogenicity of genetic variations (ABCG5 and ABCG8) is useful. Using this scheme, 11 putative pathogenic, and 12 benign variants in ABCG5 or ABCG were classified.

BACKGROUND/AIMS: Noninvasive liver fibrosis evaluation was performed in patients with nonalcoholic fatty liver disease (NAFLD). We used a quantitative method based on the hepatic volume acquired from gadoxetate disodium-enhanced (Gd-EOB-DTPA-enhanced) magnetic resonance imaging (MRI) for diagnosing advanced fibrosis in patients with NAFLD. METHODS: A total of 130 patients who were diagnosed with NAFLD and underwent Gd-EOB-DTPA-enhanced MRI were retrospectively included. Histological data were available for 118 patients. Hepatic volumetric parameters, including the left hepatic lobe to right hepatic lobe volume ratio (L/R ratio), were measured. The usefulness of the L/R ratio for diagnosing fibrosis ≥F3–4 and F4 was assessed using the area under the receiver operating characteristic (AUROC) curve. Multiple regression analysis was performed to identify variables (age, body mass index, serum fibrosis markers, and histological features) that were associated with the L/R ratio. RESULTS: The L/R ratio demonstrated good performance in differentiating advanced fibrosis (AUROC, 0.80; 95% confidence interval, 0.72 to 0.88) from cirrhosis (AUROC, 0.87; 95% confidence interval, 0.75 to 0.99). Multiple regression analysis showed that only fibrosis was significantly associated with the L/R ratio (coefficient, 0.121; p<0.0001). CONCLUSIONS: The L/R ratio, which is not influenced by pathological parameters other than fibrosis, is useful for diagnosing cirrhosis in patients with NAFLD.

Objective: Patients treated with vinorelbine(VNR)-containing chemotherapy often suffer from injection site reactions. VNR is a moderate vesicant that is well known to cause local venous damage. We conducted this study to identify clinical risk factors related to the incidence of injection site reactions caused by VNR, and whether applying a hot compress was effective for preventing such reactions.
Methods: Medical records were retrospectively investigated for 48 patients treated with chemotherapy regimens containing VNR. Injection site reactions were evaluated for every course and were graded according to the National Cancer Institute Common Toxicity Criteria (version 4.0). Gender, age, body mass index, chemotherapy regimen, dose of VNR, and volume of fluid for flushing the vein were assessed as clinical variables. A hot compress was applied to the vein proximal to the injection site during VNR injection.
Results: The injection site reactions occurred in 29 (60%) among 48 patients received intravenous VNR injection. According to multivariate analysis, use of gemcitabine (GEM) in combination with VNR showed a significant independent correlation with an increased risk of injection site reactions (p=0.019). When hot compress was applied to 21 patients, who experienced phlebitis of VNR, the injection site reaction was occurred to only three patients (p<0.001).
Conclusion: In this study, the risk factor of the injection site reaction by VNR seems to be combination of GEM. Application of hot compresses was effective for preventing injection site reactions by VNR.

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.

OBJECTIVE: Many studies have reported pre-processing effects for brain volumetry; however, no study has investigated whether non-parametric non-uniform intensity normalization (N3) correction processing results in reduced system dependency when using an atlas-based method. To address this shortcoming, the present study assessed whether N3 correction processing provides reduced system dependency in atlas-based volumetry. MATERIALS AND METHODS: Contiguous sagittal T1-weighted images of the brain were obtained from 21 healthy participants, by using five magnetic resonance protocols. After image preprocessing using the Statistical Parametric Mapping 5 software, we measured the structural volume of the segmented images with the WFU-PickAtlas software. We applied six different bias-correction levels (Regularization 10, Regularization 0.0001, Regularization 0, Regularization 10 with N3, Regularization 0.0001 with N3, and Regularization 0 with N3) to each set of images. The structural volume change ratio (%) was defined as the change ratio (%) = (100 x [measured volume - mean volume of five magnetic resonance protocols] / mean volume of five magnetic resonance protocols) for each bias-correction level. RESULTS: A low change ratio was synonymous with lower system dependency. The results showed that the images with the N3 correction had a lower change ratio compared with those without the N3 correction. CONCLUSION: The present study is the first atlas-based volumetry study to show that the precision of atlas-based volumetry improves when using N3-corrected images. Therefore, correction for signal intensity non-uniformity is strongly advised for multi-scanner or multi-site imaging trials.
