Efficacy and safety of aripiprazole or bupropion augmentation and switching in patients with treatment-resistant depression or major depressive disorder: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To report the first and largest systematic review and meta-analysis of randomized controlled trials (RCT) to evaluate the efficacy and safety of aripiprazole or bupropion augmentation and switching in patients with treatment-resistant depression (TRD) or major depressive disorder(MDD). METHODS: We conducted a systematic literature retrieval via PubMed, Embase, Web of Science, and Cochrane until April 2023 for RCT, which evaluated the efficacy and safety of aripiprazole or bupropion augmentation and switching for patients with TRD or MDD. Outcomes measured were changes in the Montgomery-Asberg Depression Rating Scale (MADRS), response and remission rate, and serious adverse events. RESULTS: Five RCTs, including 4480 patients, were included for meta-analysis. Among them, two RCTs were rated as "high risk" in three aspects (allocation concealment, blinding of participants and personnel and blinding of outcome assessment) because of the non-blind method, and the quality evaluation of the remaining works of literature was "low risk". Augmentation treatment with Aripiprazole (A-ARI) was associated with a significant higher response rate compared with augmentation treatment with bupropion (A-BUP) (RR: 1.15; 95% CI: 1.05, 1.25; P = 0.0007; I2 = 23%). Besides, A-ARI had a significant higher remission rate compared with switching to bupropion (S-BUP) (RR: 1.22; 95% CI: 1.00, 1.49; P = 0.05; I2 = 59%) and A-BUP had a significant higher remission rate compared with S-BUP (RR: 1.20; 95% CI: 1.06, 1.36; P = 0.0004; I2 = 0%). In addition, there was no significant difference in remission rate(RR: 1.05; 95% CI: 0.94, 1.17; P = 0.42; I2 = 33%), improvement of MADRS(WMD: -2.07; 95% CI: -5.84, 1.70; P = 0.28; I2 = 70%) between A-ARI and A-BUP. No significant difference was observed in adverse events and serious adverse events among the three treatment strategies. CONCLUSIONS: A-ARI may be a better comprehensive antidepressant treatment strategy than A-BUP or S-BUP for patients with TRD or MDD. More large-scale, multi-center, double-blind RCTs are needed to further evaluated the efficacy and safety of aripiprazole or bupropion augmentation and switching treatment strategies.

Forearm bone mineral density predicts screw loosening after lumbar fusion similar to lumbar Hounsfield unit value in patients with lumbar spondylolisthesis.

Preoperative bone density assessment is necessary to predict screw loosening. The forearm BMD is a useful predictor of BMD-related complications after lumbar operation. Our results show that the forearm BMD is as effective a predictor of screw loosening as the lumbar average HU value. Measurement of the forearm BMD may be a useful adjunct in predicting screw loosening following lumbar fusion. PURPOSE: To determine the relationship between forearm bone mineral density (BMD) and the risk of pedicle screw loosening in patients with lumbar spondylolisthesis. METHODS: We retrospectively evaluated 270 patients who underwent posterior lumbar interbody fusion for lumbar spondylolisthesis. The patients were divided into two groups on the basis of the with or without loose screws: the loosening group and the non-loosening group. The patient's gender, age, BMI, smoking and diabetes histories, and the operative segment were recorded as the basic information. The Hounsfield unit (HU) value for the BMD of the L1-4 lumbar was measured using computed tomography. The patient's distal one-third of the length of the radius and ulna of the non-dominant forearm was chosen as the site for dual-energy X-ray (DXA) bone density testing. RESULTS: The rate of screw loosening was 13% at a minimum 12 months follow-up. Average forearm BMD (0.461 ± 0.1 vs 0.577 ± 0.1, p < 0.001) and mean HU value (L1-4) (121.1 ± 27.3 vs 155.6 ± 32.2, p < 0.001) were lower in the screw loosening group than those in the non-loosening group. In multivariate logistic regression analysis, the forearm BMD (OR 0.840; 95%CI 0.797-0.886) and HU value (L1-4) (OR 0.952; 95%CI 0.935-0.969) were independent risk factor for screw loosening. The area under the curve (AUC) for the forearm BMD and HU value for prediction of pedicle screw loosening was 0.802 and 0.811. The forearm BMD cut-off for predicting pedicle screw loosening was 0.543 (sensitivity, 0.800; specificity, 0.864). CONCLUSIONS: The forearm BMD was an independent risk factor for loosening of the lumbar pedicle screws. The forearm BMD was a valid predictor of pedicle screw loosening in patients undergoing lumbar fusion, as was the CT HU value.

K-line tilt as a novel potential risk factor for cervical Modic change: a retrospective study.

BACKGROUND: Cervical sagittal parameters are important parameters that reflect the mechanical stress in the sagittal plane of the cervical spine and are an important basis for predicting the clinical status and prognosis of patients. Although it has been confirmed that there is a significant correlation between cervical Modic changes and some sagittal parameters. However, as a newly discovered sagittal parameter, there is no report on the relationship between the K-line tilt and the Modic changes of cervical spine. METHODS: A retrospective analysis was performed for 240 patients who underwent cervical magnetic resonance imaging scan for neck and shoulder pain. Among them, 120 patients with Modic changes, namely the MC(+) group, were evenly divided into three subgroups of 40 patients in each group according to different subtypes, namely MCI subgroup, MCII subgroup and MCIII subgroup. One hundred twenty patients without Modic changes were included in MC(-) group. We measured and compared the sagittal parameters of cervical spine among different groups, including K-line tilt, C2-C7 sagittal axial vertical distance (C2-C7 SVA), T1 slope and C2-7 lordosis. Logistic regression was used to analyse the risk factors of cervical Modic changes. RESULTS: The K-line tilt and C2-7 lordosis were significantly different between MC(+) group and MC(-) group (P < 0.05). The K-line tilt greater than 6.72° is a risk factor for Modic changes in cervical spine (P < 0.05). At the same time, the receiver operating characteristic curve showed that this change had moderate diagnostic value when the area under the curve was 0.77. CONCLUSION: This study shows that the K-line tilt greater than 6.72° is a potential risk factor for Modic changes in cervical spine. When the K-line tilt is greater than 6.72°, we should be alert to the occurrence of Modic changes. TRIAL REGISTRATION NUMBER: 2022ER023-1.

High expression of 14-3-3Æ¡ indicates poor prognosis and progression of lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is one of the leading causes of cancer-related death worldwide. 14-3-3Æ¡ is an intracellular phosphoserine-binding protein that has been proposed to be involved in tumorigenesis. However, the biofunctional role of 14-3-3Æ¡ and its clinicopathological/prognostic significance in LUAD have remained elusive. In the present study, western blot and immunohistochemical analyses of cancer tissues/cells and the corresponding normal controls were performed to verify that 14-3-3Æ¡ was upregulated in LUAD. Univariate and multivariate logistic regression analysis indicated that high expression of 14-3-3Æ¡ predicted poor overall survival and progression-free survival of patients with LUAD. Furthermore, in vivo and in vitro experiments demonstrated that overexpression of 14-3-3Æ¡ markedly promoted cell proliferation, colony formation, anchorage-independent growth and tumor growth, whereas 14-3-3Æ¡ depletion produced the opposite effects. Of note, 14-3-3Æ¡ was identified as an independent prognostic factor for patients with LUAD. Collectively, the present results revealed that high expression of 14-3-3Æ¡ may serve as an independent biomarker, contributing to poor prognosis and progression of LUAD.

Connexin 43 affects thoracic ossification of ligamentum flavum by regulating the p38 MAPK-RUNX2 signaling pathway.

This study aimed to investigate the role of connexin 43 (CX43) in thoracic ossification of ligamentum flavum (TOLF) based on the p38 mitogen-activated protein kinase (p38MAPK)-runt-related transcription factor 2 (RUNX2) pathway. Immunohistochemistry was used to detect CX43 expression in TOLF and non-TOLF patients, fibroblasts of TOLF were isolated and induced osteogenic differentiation, and CX43 expression was detected by western blot analysis (WB). In addition, si-CX43 was used to intervene CX43, and SB203580 was used to inhibit the p38MAPK. The expressions of bone differentiation marker protein were detected by WB, and the ossification ability was analyzed by alizarin red staining. The interaction between RUNX2 and CX43 was identified by dual-luciferase reporter assay. Results found that CX43 was highly expressed during TOLF, and si-CX43 could inhibit the expression of alkaline phosphatase (ALP) and osteopontin (OPN), as well as inhibit TOLF and the p38MAPK-RUNX2 pathway. In addition, SB203580 showed a synergistic effect with si-CX43 to further inhibit TOLF and the expression of RUNX2. The dual-luciferase reporter assay confirmed that RUNX2 could bind to the CX43 promoter. In conclusion, CX43 promotes TOLF, which may be mediated by p38MAPK-RUNX2, and RUNX2 binds to the CX43 promoter to form a positive feedback regulatory loop during TOLF.

[Study on the safety and effectiveness of low-dose tranexamic acid in operation of multi-level continuous thoracic ossification of ligament flavum].

OBJECTIVE: To investigate the safety and effectiveness of low-dose tranexamic acid (TXA) in operation of multi-level continuous thoracic ossification of ligament flavum (TOLF). METHODS: A clinical data of 26 patients who underwent operation for multi-level continuous TOLF and met the selection criteria between July 2015 and January 2019 was retrospectively analyzed. Among them, 13 cases (group A) were received intravenous infusion of TXA (10 mg/kg) at 15 minutes before operation, and maintained the infusion at 1 mg/(kg·h) until the end of the operation; 13 cases (group B) were received the same dose of normal saline before and during operation. There was no significant difference in gender, age, body mass index, diseased segment, and preoperative hemoglobin, platelet count, activated partial thromboplastin time, prothrombin time, international normalized ratio (INR) between the two groups ( P>0.05). The hemoglobin, platelet count, activated partial thromboplastin time, prothrombin time, INR, the number of deep vein thrombosis of the lower extremities, operation time, intraoperative blood loss, postoperative drainage volume, total blood loss, and the time of drainage tube extubation in the two groups were recorded and compared. RESULTS: All operations in the two groups were successfully completed. Compared with group B, the operation time and time of drainage tube extubation in group A were shortened, and the intraoperative blood loss, postoperative drainage volume, and total blood loss were reduced. The differences between the two groups were significant ( P<0.05). None of the two groups received blood transfusion, and the hemoglobin level of group A at 24 hours after operation was significantly higher than that of group B ( t=5.062, P=0.000). The incisions in both groups healed and sutures were removed within 2 weeks after operation, and no complications occurred. There was no significant difference between the two groups in activated partial thromboplastin time, prothrombin time, INR, and platelet count at 24 hours after operation ( P>0.05). CONCLUSION: In multi-level continuous TOLF operation, intravenous administration of low-dose TXA can effectively reduce blood loss, shorten postoperative drainage time, and does not increase the risk of complications.

Preventive effect and safety of Chinese herbal medicine mouthwash in chemotherapy-induced oral mucositis: A protocol for systematic review and meta analysis.

BACKGROUND: Oral mucositis (OM), one of the most common side effects for cancer patients who have undergone chemotherapy, can cause severe impairment to patients' functional ability and impact their quality of life, resulting in delayed and/or incomplete treatment. Traditional Chinese medicine offers empirical herbal decoctions to gargle for the prevention of chemotherapy-induced OM; however, evidence for its clinical efficacy and safety is lacking. Therefore, we provide a protocol to evaluate the preventive effect and safety of Chinese herbal medicine mouthwash in chemotherapy-induced OM. METHODS: We will comprehensively retrieve relevant articles published till August 15, 2020, in the following electronic databases: the Cochrane Library, PubMed, EMBASE, Chinese National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, Chinese Science and Technique Journals Database, and the Wan-fang Database. Only randomized controlled trials will be included. We will use the criteria provided by the Cochrane Handbook for quality assessment and risk assessment of the included studies and use the RevMan 5.3 software for meta-analysis of the preventive effect and safety. RESULTS: This study will assess the preventive effect and safety of Chinese herbal medicine mouthwash in chemotherapy-induced OM. CONCLUSION: This systematic review will provide evidence-based medical corroboration for the clinical application of the Chinese herbal medicine mouthwash in chemotherapy-induced OM.

Cervical epidural hematoma after spinal manipulation therapy: a case report.

BACKGROUND: Cervical spinal manipulation therapy is a common non-invasive treatment for neck pain and stiffness, and has been widely used in the population. However, most people do not pay attention to the potential risks of neck manipulation, such as ligament damage, fractures, and spinal cord injuries. Epidural hematoma is a disease in which blood accumulates in the epidural space of the vertebral body. This disease is usually caused by trauma or iatrogenic surgery, and may be associated with blood coagulopathies, neoplasms, or degenerative spinal disease. Reports of epidural hematoma caused by cervical spinal manipulation are rare. CASE PRESENTATION: We present the case of a patient with tetraplegia and spinal shock after neck manipulation. A physical examination of the patient on admission found tenderness in the neck and increased muscle tension in both upper limbs. The superficial sensation of the upper limb disappeared, but the deep sensation still remained. The lower extremity had 0/5 power on both sides. The sensation below the T2 level completely disappeared. A cervical magnetic resonance imaging scan showed an acute posterior epidural hematoma from the C3-T3 vertebrae. Ultimately, the patient underwent emergency hematoma removal and showed partial improvement in symptoms of paralysis during follow-up. CONCLUSIONS: Although spinal manipulation is simple and neck pain is common and recurrent in the general population, the basic condition and disease history of patients should be determined before manipulation. For high-risk patients, caution should be applied for cervical spinal manipulation or it should be prohibited. For a suspected hematoma, MRI should be used at an early stage to diagnose and locate the hematoma.

A retrospective study of concurrent radiotherapy plus S-1 for treating advanced non-small cell lung cancer.

We investigated the efficacy of concurrent radiotherapy plus S-1 (CRS) for treating unresectable stage III advanced non-small-cell lung cancer (ANSCLC).Seventy five ANSCLC patients were included in this retrospective study. Of those, 40 patients were assigned to an intervention group, and received S-1 (orally at 40 mg/m) twice daily for 14 consecutive days. Then, concurrent radiotherapy was administered in 2 Gy fractions, 5 times weekly for a total dose of 60 Gy. The other 35 patients were assigned to a control group, and underwent concurrent radiotherapy (the same as the intervention group) and cisplatin (60 mg/m on day 1 (CRC). The outcome measurements included overall response rate (ORR), overall survival (OS), progression-free survival (PFS), and toxicity.The 3-year ORR was 60.7% and 43.9% for intervention group and control group, respectively (P = .031). The median OS was 34.1 months and 25.3 months in the intervention and control groups, respectively (P = .041). The median PFS was 31.5 months for intervention group, while it was 22.4 months for control group (P = .048). No significant difference in toxicity was found between the 2 groups.The results demonstrated that the efficacy of CRS was superior to the CRC in ANSCLC patients with similar toxicity.

S-1 plus cisplatin with concurrent radiotherapy versus cisplatin alone with concurrent radiotherapy in Chinese patients with nonsmall-cell lung cancer: A multicentre randomized controlled trial.

BACKGROUND: The aim of this study was to investigate the efficacy and safety of S-1 plus cisplatin combined with concurrent radiotherapy (SCCCR) versus cisplatin alone combined with concurrent radiotherapy (CCCR) in Chinese patients with unresectable stage III nonsmall-cell lung cancer (NSCLC). METHODS: Between January 2012 and December 2014, 72 eligible Chinese patients with NSCLC were included and randomly divided into 2 groups, each having 36 patients. Patients in the SCCCR group received S-1 plus cisplatin with concurrent, radiotherapy. The other 36 patients in the CCCR group were administered cisplatin with concurrent radiotherapy. The primary outcome was the overall response rate. The secondary outcomes were overall survival (OS), progression-free survival (PFS), and adverse events. RESULTS: The 3-year overall response rates for the SCCCR and CCCR groups were 60.1% and 53.3%, respectively (P = 0.041). The median OS was 35.1 (range, 6.5-47.2) months and 24.6 (range, 2.8-24.3) months for the SCCCR and CCCR groups, respectively (P = 0.016). The median PFS for the SCCCR and CCCR groups was 31.4 (range, 5.6-39.3) months and 22.3 (range, 2.4-36.5) months, respectively (P = 0.023). The toxicity profiles were similar for both groups. CONCLUSION: The efficacy and safety of SCCCR was more encouraging compared to those of CCCR in Chinese NSCLC patients. In addition, the toxicities in both groups were tolerable.
