Comparison of automated breast volume scanning with conventional ultrasonography, mammography, and MRI to assess residual breast cancer after neoadjuvant therapy by molecular type. Clin Radiol 2023; 78:e393-e400. [PMID: 36822980 DOI: 10.1016/j.crad.2022.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 11/28/2022] [Accepted: 12/04/2022] [Indexed: 01/15/2023]
Abstract
AIM To compare the accuracy of hand-held ultrasonography (US), mammography (MG), magnetic resonance imaging (MRI), and automated breast volume scanning (ABVS) in defining residual breast cancer tumour size after neoadjuvant therapy (NAT). MATERIALS AND METHODS Patients diagnosed breast cancer and who received NAT at the Breast Center, Peking University People's Hospital, were enrolled prospectively. Imaging was performed after the last cycle of NAT. The residual tumour size, intraclass correlation coefficients (ICCs), and receiver operating characteristic (ROC) to predict pathological complete response (pCR) were analysed. RESULTS A total of 156 patients with 159 tumours were analysed. ABVS had a moderate correlation with histopathology residual tumour size (ICC = 0.666), and showed high agreement among triple-positive tumours (ICC = 0.797). With 5 mm as the threshold, the coincidence rate reached 64.7% between ABVS and pathological size, which was significantly higher than that between US, MG, MRI, and pathological size (50%, 45.1%, 41.4%; p=0.009, p=0.001, p<0.001, respectively). For ROC analysis, ABVS demonstrated a higher area under the ROC curve, but with no statistical difference, except for MG (0.855, 0.816, 0.819, and 0.788, respectively; p=0.183 for US, p=0.044 for MG, and p=0.397 for MRI, with ABVS as the reference). CONCLUSIONS The longest tumour diameter on ABVS had a moderate correlation with pathological residual invasive tumour size. ABVS was shown to have good ability to predict pCR and would appear to be a potential useful tool for the assessment after NAT for breast cancer.

Abstract
PURPOSE The relationship of CAN and BMD, fracture risk is still unclear in T2DM. The aim of the present study is to investigate the correlation between heart rate variability (HRV) and BMD in T2DM. METHODS The study included 276 patients with T2DM aged ≥ 50 years, and Cardiovascular Autonomic Reflex Tests (CARTs) were applied to divide patients into two groups: CAN ( ±). 24 h Ambulatory ECG was assessed for HRV, BMD was measured by dual-energy X-ray bone densitometry, and FRAX scores were calculated for 10-year hip fracture risk (HF1) and major osteoporotic fracture risk (MOF). Adjusted regression analysis was performed to investigate influence factors for BMD and fracture risk. ROC curve was used to analyze the optimal cut-off point of LF/HF for screening osteoporosis. RESULTS Baseline data showed significant differences in the duration of T2DM, insulin resistance index (HOMA-IR), 25-hydroxyvitamin D[25(OH)D], femoral neck BMD, hip BMD, lumbar BMD, HF1, and MOF between the CAN ( +) and CAN (-) groups. The proportion of patients with osteoporosis increased as the degree of CAN lesion increased. Correlation analysis showed that LF/HF was significantly correlated with BMD, especially with hip (r = - 0.534, p < 0.001). Regression analysis showed that LF/HF was a risk factor for reduced BMD and increased fracture risk. The optimal cut-point value for LF/HF to predict osteoporosis by ROC curve analysis was 3.17. CONCLUSIONS CAN is associated with reduced BMD and increased fracture risk in patients with T2DM, and LF/HF may have the potential to be a predictor of diabetic osteoporosis and have some clinical value in early diagnosis of diabetic osteoporosis and non-traumatic fractures in T2DM.

Abstract
Objective: To examine the application effect of the modified wire-loop snare technique in retrieving severely tilted inferior vena cava filters (IVCF). Methods: The clinical data of 18 patients (12 males and 6 females, aged (62.1±13.1) years (range: 29 to 78 years)) who underwent the modified wire-loop snare technique to retrieve IVCF at the Affiliated Hospital of Qingdao University, Qingdao Eighth People's Hospital, and Jimo District Hospital of Traditional Chinese Medicine from November 2017 to April 2022 were retrospectively analyzed. The applied filters included drum-type filters (OptEase in 7 cases, Aegisy in 2 cases) and conical filters (Celect in 6 cases and Denali in 3 cases). Preoperative CT angiography and intraoperative digital subtraction angiography showed that the filter was severely tilted and the hook was covered by hyperplastic intima of the vena cave vein. A modified wire-loop snare technique was used to retrieve drum-type filters and conical filters via femoral and jugular vein approaches, respectively. After successful puncture, the long sheath was placed, the 4 F (1 F≈0.33 mm) vertebral catheter and a snare were inserted through the long sheath, and the 5 F pigtail catheter was inserted simultaneously to guide a 0.035 inch soft guide-wire (260 cm in length) to pass through the top of the filter and turning back. The tip of the soft guide-wire was snared by the vertebral catheter and pulled out of the sheath. The 4 F vertebral catheter was inserted following the tip of the guide-wire to form a wire-loop using the vertebral catheter and the pigtail catheter. After fixing the tip and tail of the soft guide-wire in vitro, the long sheath was pushed forward to cut the hyperplastic intima and the hook was pulled away from the vena cava wall to retrieve the filter under the support of two catheters. Results: The filters were successfully retrieved in 17 cases, the operation time was (25.5±8.7) minutes (range: 15 to 45 minutes), no complication occured. The hook of one filter (Celect) penetrated out of the vena vava wall and the wire-loop could not pull the hook back into the vena cava. Then the filter was removed by laparotomy. Conclusion: The modified wire-loop snare technique could retrieve the severely tilted retrivable drum-type filters and conical filters, even when serve adhesion exists between the filter and the vena cava wall.

Abstract
Objective: To evaluate the short-term efficacy and safety of vedolizumab in patients with inflammatory bowel disease (IBD). Methods: Patients with moderate and severe active IBD at the first use of vedolizumab from May 1 to October 31, 2021 were retrospectively enrolled. Then the clinical characteristics, and the efficacy and safety of vedolizumab were evaluated. Meanwhile, the clinical response rate, biological response rate and endoscopic response rate were calculated. Multivariate analysis was used to evaluate the independent influencing factors of short-term clinical efficacy and safety. Results: A total of 78 patients (44 males and 34 females) with IBD were enrolled, with a mean age of (40.5±11.9) years. The clinical remission rate, clinical response rate, biological remission rate, biological response rate and endoscopic remission rate was 60.3% (47/78), 85.9% (67/78), 70.5% (55/78), 43.6% (34/78) and 47.0% (31/66) respectively after 14 weeks of treatment. Body mass index (BMI) ≥ 18.5 kg/m2 (HR=5.04, 95%CI: 1.50-16.91, P=0.009) and biological remission at 6 weeks of treatment (HR=15.22, 95%CI: 3.16-73.38, P=0.001) were predictors of endoscopic remission at 14 weeks of treatment. Adverse reactions occurred in 57 patients, with an incidence of 73.1%. The main manifestations were liver and kidney damage (37.2%) and infection (26.9%). Conclusions: More than half of patients with moderate and severe active IBD can achieve clinical remission after 14 weeks of vedolizumab treatment. Baseline BMI level and biological remission at 6 weeks of treatment are predictors of mucosal healing at 14 weeks. The incidence of adverse reactions is not low, although serious adverse reactions are rare in short-term treatment.

Abstract
Objective: To analyze the influence of intrinsic motivation on work burnout and the mediating effects of work stress. Methods: In 2020, questionnaire survey was conducted in 1 655 gastroenterologists working in 28 provinces of China. Mediation model was used to analyze the mediating effects of work stress in the relationship between intrinsic motivation and burnout. Resutls 1655 valid questionnaires were collected, including 1 132 women and 523 men, with an average age of 39.26. Intrinsic motivation was related to reduced level of burnout, including emotional exhaustion, dehumanization and low sense of accomplishment (β=-2.06, -1, 77 and-4.20;P<0.001). Job stress partially mediated the negative correlation between intrinsic motivation and job burnout in three dimensions, accounting for 40%, 15% and 5% (β=-1.58, -0.36 and-0.21;P<0.05), respectively. In female physicians, the intrinsic motivation was more directly related to the reduction of burnout, especially in the dimension"emotional exhaustion"(direct effect accounting for 62% in female gastroenterologists and 46% in male). Conclusions: Enhancing the intrinsic motivation of gastroenterologists can directly reduce burnout and indirectly reduce burnout by alleviating work stress. In the same work environment, female physicians' intrinsic motivation had a greater and more direct effect on reducing burnout.

Abstract
Objective: To investigate the cell cycle and apoptosis in hydroquinone (HQ) -induced malignant transformation of TK6 cells and its related regulatory mechanisms. Methods: TK6 cells were exposed to 20 μmol/L HQ, 24 h/time, once a week, for 19 weeks as experimental group and TK6 cells treated with phosphate buffer (PBS) for 19 weeks was used as control group from March 2014. In regulatory mechanism research, the cells were divided into four groups: control group, experimental group, control inhibitor group and experimental inhibitor group (inhibitor groups were added 10 μmol/L P600125) . Cell cycle and apoptosis were detected by flow cytometry. The protein expression of cell cycle-related proteins and JNK signaling pathway proteins were detected by Western blot. Results: Flow cytometry showed that compared with control group, the ratio of cells in the G0/G1 phase of the experimental group was significantly decreased (P=0.001) , and the ratio of cells in the S phase was significantly increased (P=0.002) . Western blotting demonstrated that the protein expressions of p-Rb (Ser780) , E2F1, Cyclin D1, p-p16 (Ser152) , JNK1, p-JNK1 (Thr183/Tyr185) , c-jun, p-c-jun (Ser63) (P=0.015, 0.021, 0.001, 0.001, 0.005, 0.001, 0.039, 0.003) were up-regulated, while the protein expressions of Rb (P=0.048) and p16 (P=0.002) were significantly down-regulated. After exposed to SP600125, compared with experimental group, there were no significant changes in cell cycle distribution (P=0.946) and apoptosis rate (P=0.923) in experimental inhibitor group. The expression of c-jun (P=0.040) protein was down-regulated, while the expression of Rb (P=0.027) protein was up-regulated in experimental inhibitor group. Conclusion: In HQ-induced TK6 cells malignant transformation, the cell cycle is arrested in the S phase, and the p16/pRb signaling pathway is inhibited, while the JNK signaling pathway is activated. However, the activated JNK signaling pathway may not be involved in the regulation of cell cycle.

Abstract
BACKGROUND The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Abstract
Long non-coding RNAs (lncRNAs) and small nucleolar RNA host gene 6 (SNHG6) have attracted extensive attention due to their involvement in various pathological processes. However, the functional role of lncRNA SNHG6 in depression-like behavior induced by hypothyroidism is still largely unknown. Our study was designed to explore the biological role of lncRNA SNHG6 in depression-like behavior induced by hypothyroidism and the underlying mechanisms. First, the depression-like behavior of hypothyroid mice was investigated after lncRNA SNHG6 knockdown. Subsequently, the regulation of the methylation levels of the brain-derived neurotrophic factor (BDNF) promoters by lncRNA SNHG6 was evaluated. To reveal the underlying mechanisms of lncRNA SNHG6 in the methylation of the BDNF promoters, RNA pull-down assays, RNA immunoprecipitation, and co-immunoprecipitation were performed. Further experiments were also conducted to investigate the roles of DNA (cytosine-5)-methyltransferase 1 (DNMT1) in the depression-like behavior induced by hypothyroidism. In this study, elevated levels of lncRNA SNHG6 were noted in the hippocampus in hypothyroid mice. Function assays proved that lncRNA SNHG6 knockdown alleviated the depression-like behavior induced by hypothyroidism. Furthermore, a mechanistic investigation validated that lncRNA SNHG6 stabilized DNMT1 by blocking UHRF1-mediated DNMT1 ubiquitination, which increased the methylation levels of the BDNF promoters. Moreover, DNMT1 was found to be involved in depression-like behavior in hypothyroid mice. Our findings revealed a novel mechanism by which lncRNA SNHG6 promotes the methylation levels of the BDNF promoters by stabilizing DNMT1 and sheds light on potential therapeutic strategies for depression-like behavior induced by hypothyroidism.
