RESUMO

Objective: Robot-assisted thoracoscopic surgery typically necessitates the use of multiple ports. The new single-port robotic system (da Vinci SP system) platform is designed to perform uniportal surgery. The purpose of this clinical trial is to evaluate the feasibility, efficacy, and safety of the da Vinci SP system when used for anatomical lung resection. Methods: Patients diagnosed with clinical stage I lung cancer requiring anatomical lung resections were considered eligible for this trial. The primary outcome measure was the rate of conversion, whereas the secondary objective focused on assessing the incidence of perioperative complications. Results: The study included 35 patients with a median age of 63 years (range, 48-74 years). Of these, 30 underwent lobectomy and 5 received segmentectomy. All surgeries were successfully performed using a subcostal approach, except for 1 patient, who required a thoracotomy conversion due to bleeding (conversion rate: 2.9%). The median docking time was 2 minutes (range, 1-8 minutes). For the 34 patients who completed uniportal surgery, the median total operating time was 194 minutes (range, 63-405 minutes), whereas the console time was 153 minutes (range, 93-267 minutes). The median number of harvested nodes was 13 (range, 5-37), while the median number of nodal stations was 6 (rang, 4-8). There were no in-hospital fatalities, and the median postoperative stay was 3 days (range, 2-12 days). Conclusions: This study demonstrates the feasibility and safety of using the da Vinci SP system for anatomical lung resection through a subcostal approach. ClinicalTrialsgov identifier: NCT05535712.

RESUMO

BACKGROUND: Focal liver lesions (FLLs) are a common form of liver disease, and identifying accurate pathological types is required to guide treatment and evaluate prognosis. PURPOSE: To compare and analyze the application effect of contrast-enhanced ultrasound (CEUS) and conventional ultrasound (US) in the clinical diagnosis of focal liver lesions. MATERIAL AND METHODS: A retrospective analysis was performed on 682 patients with space-occupying liver lesions admitted to our hospital between December 2015 and August 2021. Of these, 280 underwent CEUS-guided biopsies and 402 underwent conventional US biopsies, with the results of each biopsy subsequently compared between the two groups. The success rate and accuracy of the biopsies and their relationship with different pathological features were also analyzed. RESULTS: The success rate, sensitivity, diagnostic accuracy, positive predictive value, and negative predictive value of the CEUS group were significantly higher than those of the US group (P < 0.05). Lesion size accuracy in the CEUS group was significantly higher than that in the US group (89.29% vs. 40.55%; P < 0.05). Lesion type accuracy in the CEUS group was significantly higher than that in the US group (86.49% vs. 43.59%), and the difference between the two groups was statistically significant (P < 0.05). The logistic regression analysis indicated that malignant lesions, lesions ≥5 cm, and lesions ≤1 cm were independent factors affecting the success rate of the puncture procedure (P < 0.05). CONCLUSION: The sensitivity, specificity, and diagnostic accuracy of lesion size and type in the CEUS group were higher than those in the US group.

RESUMO

OBJECTIVE: Sports-related concussion management in collegiate athletes has been focused on return-to-play. However, resuming schoolwork without a gradual stepwise reintroduction contributes to symptom exacerbation, delayed recovery, and adverse academic performance. Return-to-learn guidelines are limited by a lack of sensitivity in methods monitoring cognitive function. This study evaluated 2 neuropsychological tests, the Sternberg test and the Paced Auditory Serial Addition Test (PASAT), with high ceilings for sensitivity to deficits in speed of information processing, cognitive efficiency, and complex attention. SETTING: Academic center research laboratory. PARTICIPANTS: We recruited 56 male and female collegiate contact and noncontact sports athletes. They were categorized into as follows: (1) nonconcussed (n = 23; 7F, 16M); (2) chronic (n = 21; 4F, 17M), at least 1 year from their last concussion; and (3) acute (n = 12; 1F, 11M), within 2 weeks from concussion. DESIGN: Observational cohort study. MAIN MEASURES: The PASAT assesses complex attention. The Sternberg test examines processing speed and cognitive efficiency. Cognitive difficulty increases with progression through the tasks for both the PASAT and the Sternberg test. The mean outcome differences of the 3 groups (nonconcussed, acute, and chronic) across the 3 or 4 conditions (difficulty level) were measured with repeated-measures analysis of variance and subsequent pairwise comparison. RESULTS: For processing speed (Sternberg reaction time), the acute group responded slower than the chronic group on the medium (P = .021, Bonferroni corrected) and hard difficulty tasks (P = .030, Bonferroni corrected). For cognitive efficiency (Sternberg reaction time variability), the acute group had increased reaction time variability compared with the chronic group on the medium difficulty task (P = .04, Bonferroni corrected). For complex attention (PASAT omissions), there was a difference between the acute and nonconcussed groups on the moderate-hard difficulty trial (P = .023, least significant difference [LSD] corrected) and between the acute and chronic groups for hard difficulty trial (P = .020, LSD corrected). The acute group performed worse, with progressively shorter interstimulus intervals. CONCLUSION: Neuropsychological testing without ceiling effects can capture higher-level cognitive dysfunction and use of such tests can contribute to the understanding of how collegiate athletes are affected by SRC. Future studies can investigate optimal testing batteries that include neuropsychological testing with high ceilings and whether the pattern of performance has implications for the return-to-learn process after SRC in the college setting.

RESUMO

OBJECTIVE: In recent years, there has been an increasing focus on minimally invasive mediastinal surgery using a trans-subxiphoid single-port thoracoscopic approach. Despite its potential advantages, the widespread adoption of this method has been hindered by the intricate surgical maneuvers required within the confined retrosternal space. Robotic surgery offers the potential to overcome the limitations inherent in the thoracoscopic technique. METHODS: This was a clinical trial (NCT05455840) to evaluate the feasibility and safety of utilizing the da Vinci® SP system (Intuitive Surgical, Sunnyvale, CA, USA) for trans-subxiphoid single-port surgery in patients with anterior mediastinal disease. The primary endpoints encompassed conversion rates and the secondary endpoints included the occurrence of perioperative complications. RESULTS: Between August 2022 and April 2023, a total of 15 patients (7 men and 8 women; median age = 56 years, interquartile range [IQR]: 49 to 65 years) underwent trans-subxiphoid robotic surgery using da Vinci SP platform for maximal thymectomy (n = 2) or removal of anterior mediastinal masses (n = 13). All surgical procedures were carried out with success, with no need for conversion to open surgery or the creation of additional ports. The median docking time was 2 min (IQR: 1 to 4 min), while the console time had a median of 152 min (IQR: 95 to 191 min). There were no postoperative complications and patients experienced a median postoperative hospital stay of 2 days with no unplanned 30-day readmission. CONCLUSIONS: This study shows that trans-subxiphoid single-port robotic surgery employing the da Vinci SP system in patients with anterior mediastinal disease is clinically viable with acceptable safety and short-term outcomes.

RESUMO

Ileostomy diverts the flow of feces, which can result in malnutrition in the distal part of the intestine. The diversity of the gut microbiota consequently decreases, ultimately leading to intestinal dysbiosis and dysfunction. This condition can readily result in diversion colitis (DC). Potential treatment strategies include interventions targeting the gut microbiota. In this case study, we effectively treated a patient with severe DC by ileostomy and allogeneic fecal microbiota transplantation (FMT). A 69-year-old man presented with a perforated malignant tumor in the descending colon and an iliac abscess. He underwent laparoscopic radical sigmoid colon tumor resection and prophylactic ileostomy. Follow-up colonoscopy 3 months postoperatively revealed diffuse intestinal mucosal congestion and edema along with granular inflammatory follicular hyperplasia, leading to a diagnosis of severe DC. After two rounds of allogeneic FMT, both the intestinal mucosal bleeding and edema significantly improved, as did the diversity of the gut microbiota. The positive outcome of allogeneic FMT in this case highlights the potential advantages that this procedure can offer patients with DC. However, few studies have focused on allogeneic FMT, and more in-depth research is needed to gain a better understanding.

RESUMO

The endogenous incretins glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) possess neurotrophic, neuroprotective, and anti-neuroinflammatory actions. The dipeptidyl peptidase 4 (DPP-4) inhibitor sitagliptin reduces degradation of endogenous GLP-1 and GIP, and, thereby, extends the circulation of these protective peptides. The current nonhuman primate (NHP) study evaluates whether human translational sitagliptin doses can elevate systemic and central nervous system (CNS) levels of GLP-1/GIP in naive, non-lesioned NHPs, in line with our prior rodent studies that demonstrated sitagliptin efficacy in preclinical models of Parkinson's disease (PD). PD is an age-associated neurodegenerative disorder whose current treatment is inadequate. Repositioning of the well-tolerated and efficacious diabetes drug sitagliptin provides a rapid approach to add to the therapeutic armamentarium for PD. The pharmacokinetics and pharmacodynamics of 3 oral sitagliptin doses (5, 20, and 100 mg/kg), equivalent to the routine clinical dose, a tolerated higher clinical dose and a maximal dose in monkey, were evaluated. Peak plasma sitagliptin levels were aligned both with prior reports in humans administered equivalent doses and with those in rodents demonstrating reduction of PD associated neurodegeneration. Although CNS uptake of sitagliptin was low (cerebrospinal fluid (CSF)/plasma ratio 0.01), both plasma and CSF concentrations of GLP-1/GIP were elevated in line with efficacy in prior rodent PD studies. Additional cellular studies evaluating human SH-SY5Y and primary rat ventral mesencephalic cultures challenged with 6-hydroxydopamine, established cellular models of PD, demonstrated that joint treatment with GLP-1 + GIP mitigated cell death, particularly when combined with DPP-4 inhibition to maintain incretin levels. In conclusion, this study provides a supportive translational step towards the clinical evaluation of sitagliptin in PD and other neurodegenerative disorders for which aging, similarly, is the greatest risk factor.

RESUMO

TECHNIQUE: The surgical management for high-output postoperative chylothorax typically necessitates ligation of the thoracic duct (TD) above the leak site and/or sealing the leak with a clip. However, pinpointing these structures during subsequent surgeries can be challenging due to their variable course and the presence of traumatized tissues surrounding the leak area. In response to this, we have developed a novel, fluorescence-guided technique that significantly enhances intraoperative identification of the leak point and the TD. This method was applied in the case of a 52-year-old man suffering from refractory chylothorax following a previous lung cancer surgery. This study documents the surgical procedure and includes a video vignette for a comprehensive understanding. RESULTS: A bilateral inguinal lymph node injection of saline (10 mL), guided by ultrasound and containing 2.5 mg/mL indocyanine green (ICG), was administered 20 min prior to surgery. During thoracoscopic exploration, the leak point was precisely pinpointed in the right paratracheal area by transitioning from bright light to fluorescent mode. The TD was clearly identified, and upon ligation, there was no further leakage of fluorescent lymph, indicating a successful closure of the lymphatic structure. The surgery proceeded uneventfully, and the patient was able to resume oral intake on the third postoperative day. There was no evidence of recurring symptoms, leading to his discharge. CONCLUSION: The intralymphatic injection of ICG offers a rapid visualization of the TD's anatomy and can effectively pinpoint the leak point, even amidst traumatized tissues. Moreover, it provides prompt feedback on the efficacy of ligation.

RESUMO

BACKGROUND: In a recent genome-wide association study, novel genetic variations of WNT9A were reported to be involved in the etiopathogenesis of thumb osteoarthritis (TOA) in Caucasians. Our purposes were to replicate the association of WNT9A with the development of TOA in the Chinese population and to further unveil the functional role of the risk variants. METHODS: SNP rs11588850 of WNT9A were genotyped in 953 TOA patients and 1124 healthy controls. The differences of genotype and allele distributions between the patients and healthy controls were evaluated using the Chi-square test. Luciferase Reporter Assay was performed to investigate the influence of variant on the gene expression. RESULTS: There was significantly lower frequency of genotype AA in TOA patients than in the controls 74.9% vs. 81.9%, p < 0.001). The frequency of allele A was remarkably lower in the patients than in the controls (86.3% vs. 90.5%, p < 0.001), with an odds ratio of 0.66 (95% CI = 0.54-0.80). Luciferase Reporter Assay showed that the construct containing mutant allele G of rs11588850 displayed 29.1% higher enhancer activity than the wild allele A construct (p < 0.05). CONCLUSIONS: Allele G of rs11588850 was associated with the increased risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA.

RESUMO

OBJECTIVE: Video-based pose estimation is an emerging technology that shows significant promise for improving clinical gait analysis by enabling quantitative movement analysis with little costs of money, time, or effort. The objective of this study is to determine the accuracy of pose estimation-based gait analysis when video recordings are constrained to 3 common clinical or in-home settings (ie, frontal and sagittal views of overground walking and sagittal views of treadmill walking). METHODS: Simultaneous video and motion capture recordings were collected from 30 persons after stroke during overground and treadmill walking. Spatiotemporal and kinematic gait parameters were calculated from videos using an open-source human pose estimation algorithm and from motion capture data using traditional gait analysis. Repeated-measures analyses of variance were then used to assess the accuracy of the pose estimation-based gait analysis across the different settings, and the authors examined Pearson and intraclass correlations with ground-truth motion capture data. RESULTS: Sagittal videos of overground and treadmill walking led to more accurate measurements of spatiotemporal gait parameters versus frontal videos of overground walking. Sagittal videos of overground walking resulted in the strongest correlations between video-based and motion capture measurements of lower extremity joint kinematics. Video-based measurements of hip and knee kinematics showed stronger correlations with motion capture versus ankle kinematics for both overground and treadmill walking. CONCLUSION: Video-based gait analysis using pose estimation provides accurate measurements of step length, step time, and hip and knee kinematics during overground and treadmill walking in persons after stroke. Generally, sagittal videos of overground gait provide the most accurate results. IMPACT: Many clinicians lack access to expensive gait analysis tools that can help identify patient-specific gait deviations and guide therapy decisions. These findings show that video-based methods that require only common household devices provide accurate measurements of a variety of gait parameters in persons after stroke and could make quantitative gait analysis significantly more accessible.

Allele G of rs11588850 may add to the risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA.

RESUMO

BACKGROUND: Early catheter failure is the main reason for peritoneal dialysis (PD) failure, which often causes patients to withdraw from PD. Reducing the early catheter failure is critical to increase the acceptance of PD. The purpose of our study was to establish a risk stratification model to minimize early catheter failure. METHODS: A retrospective study with patients underwent PD catheter placement from January 2013 to March 2022 was conducted. The primary outcome event was early catheter failure. Univariate and multivariable logistic regression were performed to select potential risk predictors. A risk stratification model and a clinical procedure were established. The effectiveness of the model was evaluated by external validation. RESULTS: A total of 432 patients were finally enrolled in the study. The risk for early catheter failure was associated with younger age (odds ratio [OR], 0.930; 95% confidence interval [95% CI], 0.884 to 0.972; p = 0.002), lower body mass index (BMI) (OR, 0.797; 95% CI, 0.629 to 0.964; p = 0.036), and lower albumin (ALB) levels (OR, 0.881; 95% CI, 0.782 to 0.985; p = 0.036). The risk stratification model was established and performed great discrimination capability with AUC of 0.832 (cut-off value: 0.061, sensitivity: 0.853, specificity: 0.812). The model proved to be effective in external validation; the rate of early catheter failure was dropped off from 4.1% to 0%. CONCLUSIONS: We established an effective risk stratification model, by which patients with high risk of early catheter failure could be precisely identified. The clinical procedure based on the model was proved to be helpful to minimize early catheter failure.

RESUMO

The poor prognosis of hepatocellular carcinoma (HCC) was ascribed to metastasis. Targeted therapy aiming at the molecules along the metastatic pathway is a promising therapeutic strategy. Among them, hydrogen peroxide inducible clone-5 (Hic-5) is highlighted. Hic-5, discovered as a reactive oxygen species (ROS)-inducible gene, was identified to be an adaptor protein in focal adhesion and a critical signaling mediator upregulated in various cancers including HCC. Moreover, Hic-5 may regulate epithelial-mesenchymal transition (EMT) transcription factor Snail and its downstream mesenchymal genes including fibronectin and matrix metalloproteinase-9 required for migration and invasion of HCC. However, the comprehensive Hic-5-mediated pathway was not established and whether Hic-5 can be a target for preventing HCC progression has not been validated in vivo. Using whole-transcriptome mRNA sequencing, we found reactive oxygen species modulator (ROMO) and ZNF395 were upregulated by Hic-5 in a patient-derived HCC cell line, HCC372. Whereas ROMO was involved in Hic-5-mediated ROS signaling, ZNF395 locates downstream of Snail for mesenchymal genes expression required for cell migration. Also, ZNF395 but not ROMO was upregulated by Hic-5 for migration in another patient-derived HCC cell line, HCC374. Further, by in vivo knock down of Hic-5 using the Stable Nucleic Acids Lipid nanoparticles (SNALP)-carried Hic-5 siRNA, progression of HCC372 and HCC374 in SCID mice was prevented, coupled with the decrease of the downstream mesenchymal genes. Our study provides the preclinical evidence that targeting Hic-5 is potentially able to prevent the progression of HCCs with Hic-5 overexpression.

RESUMO

BACKGROUND: Non-small cell lung cancer (NSCLC) is one of the most lethal malignancies worldwide. A novel Chinese medicine formula-01 (NCHF-01) has shown significant clinical efficacy in the treatment of NSCLC, but the mechanism of this formula in the treatment of NSCLC is not fully understood. The aim of this study is to investigate the molecular mechanism of NCHF-01 in inhibiting NSCLC. METHODS: Lewis lung cells (LLC) tumor bearing mice were established to detect the tumor inhibitory effect of NCHF-01. The morphological changes of tissues and organs in LLC tumor-bearing mice were detected by hematoxylin-eosin (HE) staining. NSCLC cells were treated by NCHF-01. The effects of cell viability and proliferation were detected by MTT and crystal violet staining experiment. Flow cytometry was used to detect cell cycle, apoptosis and reactive oxygen species (ROS). Network pharmacology was used to predict the mechanism of its inhibitory effect of NSCLC. Western blot and immunohistochemistry (IHC) were used to detect the expression of related proteins. RESULTS: NCHF-01 can inhibit tumor growth in LLC tumor-bearing mice, and has no obvious side effects on other tissues and organs. NCHF-01 could inhibit cell viability and proliferation, induce G2/M phase arrest and apoptosis, and promote the increase of ROS level. Network pharmacological analysis showed that NCHF-01 exerts anti-NSCLC effects through various biological processes such as oxidative stress and central carbon metabolism. NCHF-01 can reduce the protein expression and enzyme activity of the key enzymes 6-phosphate glucose dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD) in the pentose phosphate pathway (PPP). CONCLUSIONS: NCHF-01 can inhibit NSCLC through oxidative stress dependent on the PPP.

RESUMO

Introduction. Oxymatrine is a natural quinazine alkaloid extracted from Sophora flavescens and has many medicinal values. Oxymatrine showed protective effects, viral inhibition and effects against lung cancer.Hypothesis/Gap Statement. Individuals with lung cancer exhibit heightened vulnerability to COVID-19 infection due to compromised immune function. In conjunction with COVID-19, it is hypothesized that oxymatrine may exert potent pharmacological effects on lung cancer patients.Aim. The objective of this study was to assess the pharmacological mechanisms and targets of oxymatrine in relation to COVID-19 lung cancer.Methodology. Utilizing network pharmacology analysis, a selection of 2628 genes were identified as co-targets for both COVID-19 and lung cancer. Subsequently, a clinicopathological analysis was conducted by integrating RNA-Seq and clinical data obtained from the TCGA-LUAD lung cancer dataset, which was acquired from the official TCGA website. The identification of pharmacological targets for oxymatrine was accomplished through the utilization of various databases including Pharm mapper, SWISS Target prediction, and STITCH. These identified targets were further investigated for protein-protein interaction (PPI) using STRING, as well as for gene ontology (GO) and KEGG pathways.Results. The effects of oxymatrine on COVID-19-induced lung cancer were mediated by immune regulation, cytoprotection, antiviral, and anti-inflammatory activities, immune regulation, and control of related signalling pathways, including the formation of the neutrophil extracellular trap, phagosome, Toll-like receptor signalling pathway, apoptosis, proteoglycans in cancer, extracellular matrix disassembly, and proteolysis involved in cellular protein catabolism. Furthermore, important substances and genes like ALB, MMP3, MMP1, and TLR4 may affect how oxymatrine suppresses lung cancer/COVID-19 development.Conclusion. To treat COVID-19 or lung cancer paired with COVID-19, oxymatrine may improve the therapeutic efficacy of current clinical antiviral medicines and immunotherapy.

RESUMO

Objectives: Endoscopic thoracic sympathectomy may be complicated by the onset of disabling compensatory sweating (CS). The objective of this case series is to report the 2-year outcomes after robotic sympathetic trunk reconstruction (STR) for the reversal of CS in patients who had undergone endoscopic thoracic sympathectomy. Methods: We prospectively followed-up a total of 23 patients who had undergone robotic STR because of intolerable CS between October 2017 and January 2021. A visual analog scale ranging from 0 to 10 (with 10 indicating the highest degree) was used to assess the severity of CS at different anatomical locations, thermoregulatory alterations, and gustatory hyperhidrosis. Measurements were performed before STR and at 6-month and 2-year follow-up. Results: The mean age of the study participants was 43.3 ± 7.8 years, and 20 (87%) were men. The reversal procedure was performed after a mean of 19.6 ± 7.8 years from endoscopic thoracic sympathectomy. In all patients, nerve defects were successfully bridged using sural nerves (mean length, 9.7 cm on the right and 9.8 cm on the left). No cases of Horner syndrome were noted. At 6 postoperative months, the severity of CS decreased significantly at all body surface areas. The observed improvements were effectively maintained at 24 post-STR months. There was no evidence of either recurrent hyperhidrosis at the primary site or transition of CS to other anatomical locations. Similar improvements were evident for thermoregulatory alterations and gustatory hyperhidrosis. Conclusions: Robotic STR is safe and effective in reversing intolerable CS after endoscopic thoracic sympathectomy.

RESUMO

CO2 emissions have become increasingly prominent in China, and the primary emitters are economic belts that are spread throughout China. Two major economic belts, i.e., the Yangtze River Economic Belt (YTREB) and the Yellow River Economic Belt (YREB). Combined with stochastic impacts by regression on population, affluence and technology model, the spatial Durbin model under the space-and-time fixed effect and the Geographical and Time-Weighted Regression are employed to explore the spatio-temporal distribution characteristics and heterogeneous drivers of CO2 emissions in the two economic belts. The results are as follows. First, CO2 emissions exhibit obvious spatial correlation features in the YREB, but no such obvious spatial correlation is found in the YRETB. Second, in the YREB, the magnitude of the total influencing factors on CO2 emissions follows an order where affluence (A) is the biggest driver, followed by energy intensity (EI), technology (TEC) and openness (OP), while the biggest driver in the YRETB is industrial structure supererogation (ISS), followed by population (P), energy intensity (EI), and affluence (A). Both direct and spatial spillover effects of the drivers are observed in the two economic belts. Third, the CO2 emissions show a notable temporal lag effect in the YREB, but not in the YRETB. Fourth, the effects of the CO2 emission drivers illustrate significant spatio-temporal heterogeneity in the two economic belts.
