RESUMO
Harmine is present in a variety of medicinal plants, and its effects on colon cancer cells remain unclear. Here, we found that harmine exhibited significant inhibitory effects on the proliferation of colon cancer cells by inhibiting the phosphorylation levels of the FAK/AKT and ERK1/2/CREB. Furthermore, harmine also inhibited the migration of colon cancer cells and suppressed the expression levels of MMP-2, MMP-9, and VEGF. Additionally, harmine-induced apoptosis in colon cancer cells by regulating the expression of Bcl-2 and Bax. In conclusion, our findings suggest that harmine exerts a significant inhibitory effect on the development of colon cancer cells.
RESUMO
BACKGROUND: More than 50% of esophageal cancer patients are diagnosed with advanced diseases and commonly experience dysphagia, some of whom even have tracheoesophageal fistula. Self-expandable metal stent (SEMS) is one of the recommended palliative methods, although complications such as chest pain and stent migration are not uncommon. The goal of this study was to examine the predictors of stent migration. METHODS: We conducted a retrospective cohort study to include patients with esophageal cancer and dysphagia/tracheoesophageal fistula. Clinicopathological information, stent characteristics and patient outcomes were collected for analysis, while side-effects of SEMS were recorded, potential predictors were examined, and patients' nutritional outcomes were compared in the migration and non-migration groups. RESULTS: A total of 54 patients with esophageal cancer who received fully covered SEMS between 2013 and 2022 were included. We found tumor across the esophagogastric junction (adjusted odds ratio (OR) = 32.64, P = 0.01) and the female sex (adjusted OR = 12.5, P = 0.02) were significant predictors for stent migration. There was a decreasing tendency in body mass index/body weight in migration and non-migration groups, but the former had a steeper downslope. CONCLUSION: Fully covered SEMS is a safe and effective strategy to palliate dysphagia or fistula. Tumor across esophagogastric junction and the female sex were higher risk predictors of stent migration. A careful patient selection would optimize the effects of SEMS placement, especially in those with short-expected lifespan.
RESUMO
Background and Objectives: Lung cancer is a leading cause of cancer mortality in Taiwan. With rapid advancement of targeted therapeutics in non-small cell lung cancers, next-generation sequencing (NGS) is becoming an important tool for biomarker testing. In this study, we describe institutional experience of NGS analysis in non-small cell carcinoma (NSCLC). Materials and Methods: A cohort of 73 cases was identified from the institutional pathology archive in the period between November 2020 and December 2022. Results: Adenocarcinoma was the most common histologic type (91.8%). Most patients presented with stage IIIB and beyond (87.7%). Twenty-nine patients (39.7%) were evaluated at the time of initial diagnosis, while the others had received prior chemotherapy or targeted therapy. The most frequently mutated gene was EGFR (63%), and this was followed by TP53 (50.7%), KRAS (13.7%), RB1 (13.7%), and CDKN2A (13.7%). Clinically actionable mutations associated with a guideline-suggested targeted therapy were identified in 55 cases (75.3%) overall, and in 47.1% of cases excluding EGFR TKI-sensitizing mutation. Biomarkers other than EGFR TKI-sensitizing mutations were compared. Cases without TKI-sensitizing EGFR mutation had more level 1 or 2 biomarkers (excluding EGFR TKI-sensitizing mutations) than cases with TKI-sensitizing EGFR mutations (47.1% versus 20.1%, p = 0.016). Progressive disease was associated with co-occurrence of clinically actionable mutations (20.5% versus 0%, p < 0.05). Eight of the nine cases with co-occurring actionable genetic alternations had an EGFR mutation. After an NGS test, 46.1% of actionable or potentially actionable genetic alternations led to patients receiving a matched therapy. Conclusions: Our study demonstrated that NGS analysis identifies therapeutic targets and may guide treatment strategies in NSCLC. NGS tests may be advantageous over multiple single-gene tests for optimization of treatment plans, especially for those with non-EGFR mutations or those with progressive disease.

Extracting lithium from seawater has emerged as a disruptive platform to resolve the issue of an ever-growing lithium shortage. However, achieving highly efficient and durable lithium extraction from seawater in an energy-efficient manner is challenging, as imposed by the low concentration of lithium ions (Li+) and high concentration of interfering ions in seawater. Here, we report a facile and universal strategy to develop photothermal "ion pumps" (PIPs) that allow achieving energy-efficient, augmented, and durable lithium extraction from seawater under sunlight. The key design of PIPs lies in the function fusion and spatial configuration manipulation of a hydrophilic Li+-trapping nanofibrous core and a hydrophobic photothermal shell for governing gravity-driven water flow and solar-driven water evaporation. Such a synergetic effect allows PIPs to achieve spontaneous, continuous, and augmented Li+ replenishment-diffusion-enrichment, as well as circumvent the impact of concentration polarization and scaling of interfering ions. We demonstrate that our PIPs exhibit dramatic enhancement in Li+ trapping rate and outstanding Li+ separation factor yet have ultralow energy consumption. Moreover, our PIPs deliver ultrastable Li+ trapping performance without scaling even under high-concentration interfering ions for 140 h operation, as opposed to the significant decrease of nearly 55.6% in conventional photothermal configuration. The design concept and material toolkit developed in this work can also find applications in extracting high-value-added resources from seawater and beyond.
RESUMO
BACKGROUND: Patients with locally advanced esophageal squamous cell carcinoma (ESCC) following neoadjuvant chemoradiotherapy (nCRT) may not always receive resection despite the possible achievement of a pathologic complete response (pCR) being associated with superior survival benefit. We aimed to compare outcomes among ESCC patients with or without pCR and those refusing surgery. METHODS: In total, 111 medically operable, non-cervical ESCC patients after the same protocol of nCRT (platinum/5-fluorouracil plus radiation 50Gy) were prospectively enrolled between 2011 and 2021. Eighty-three of them underwent esophagectomy comprising pCR (n = 32) and non-pCR (n = 51), while 28 operable patients declined surgery (refusal-of-surgery group). Predictors and survival data were analyzed. RESULTS: In terms of esophagectomy, 38.5% (32/83) patients achieved pCR. The pCR group exhibited better pretreatment performance status than the non-pCR group (adjusted odds ratio: 0.11, 95% confidence interval: 0.03-0.58; p = 0.01). Among pCR, non-pCR, and refusal-of-surgery groups, the 5-year overall survival (OS) rates were 56%, 29% and 50% (p = 0.08) and progression-free survival (PFS) rates were 52%, 28% and 36% (p = 0.07) respectively. The pCR group had significantly better OS and PFS than the non-PCR group (adjusted hazard ratio: 2.33 and 1.93, p = 0.02 and 0.049 respectively) but not the refusal-of-surgery group. CONCLUSION: Better pretreatment performance status is associated with higher chance of pCR. Consistent with previous studies, we found attainment of pCR confers the best OS and PFS. Suboptimal OS in the refusal-of-surgery group reflects some of them would have residual disease in addition to complete remission. Further studies are needed to identify prognostic factors of pCR to select candidates who could validly decline esophagectomy.

The umpolung functionalization of imines bears vast synthetic potential, but polarity inversion is less efficient compared with the carbonyl counterparts. Strong nucleophiles are often required to react with the N-electrophiles without catalytic and stereochemical control. Here we show an effective strategy to realize umpolung of imines promoted by organocatalytic aromatization. The attachment of strongly electron-withdrawing groups to imines could enhance the umpolung reactivity by both electronegativity and aromatic character, enabling the direct amination of (hetero)arenes with good efficiencies and stereoselectivities. Additionally, the application of chiral Brønsted acid catalyst furnishes (hetero)aryl C-N atropisomers or enantioenriched aliphatic amines via dearomative amination from N-electrophilic aromatic precursors. Control experiments and density functional theory calculations suggest an ionic mechanism for the umpolung reaction of imines. This disconnection expands the options to forge C-N bonds stereoselectively on (hetero)arenes, which represents an important synthetic pursuit, especially in medicinal chemistry.
RESUMO
This study investigated whether oral supplementation with protease-soluble chicken type II collagen (PSCC-II) mitigates the progression of anterior cruciate ligament transection (ACLT)-induced osteoarthritis (OA) in rats. Eight-week-old male Wistar rats were randomly assigned to the following groups: control, sham, ACLT, group A (ACLT + pepsin-soluble collagen type II collagen (C-II) with type I collagen), group B (ACLT + Amano M-soluble C-II with type I collagen), group C (ACLT + high-dose Amano M-soluble C-II with type I collagen), and group D (ACLT + unproteolyzed C-II). Various methods were employed to analyze the knee joint: nociceptive tests, microcomputed tomography, histopathology, and immunohistochemistry. Rats treated with any form of C-II had significant reductions in pain sensitivity and cartilage degradation. Groups that received PSCC-II treatment effectively mitigated the ACLT-induced effects of OA concerning cancellous bone volume, trabecular number, and trabecular separation compared with the ACLT alone group. Furthermore, PSCC-II and unproteolyzed C-II suppressed ACLT-induced effects, such as the downregulation of C-II and upregulation of matrix metalloproteinase-13, tumor necrosis factor-α, and interleukin-1ß. These results indicate that PSCC-II treatment retains the protective effects of traditional undenatured C-II and provide superior benefits for OA management. These benefits encompass pain relief, anti-inflammatory effects, and the protection of cartilage and cancellous bone.

Osteoarthritis (OA) is the most common form of arthritis and joint disorder worldwide. Metabolic reprogramming of osteoarthritic chondrocytes from oxidative phosphorylation to glycolysis results in the accumulation of lactate from glycolytic metabolite pyruvate by lactate dehydrogenase A (LDHA), leading to cartilage degeneration. In the present study, we investigated the protective effects of the intra-articular administration of oxamate (LDHA inhibitor) against OA development and glycolysis-related protein expression in experimental OA rats. The animals were randomly allocated into four groups: Sham, anterior cruciate ligament transection (ACLT), ACLT + oxamate (0.25 and 2.5 mg/kg). Oxamate-treated groups received an intra-articular injection of oxamate once a week for 5 weeks. Intra-articular oxamate significantly reduced the weight-bearing defects and knee width in ACLT rats. Histopathological analyses showed that oxamate caused significantly less cartilage degeneration in the ACLT rats. Oxamate exerts hypertrophic effects in articular cartilage chondrocytes by inhibiting glucose transporter 1, glucose transporter 3, hexokinase II, pyruvate kinase M2, pyruvate dehydrogenase kinases 1 and 2, pyruvate dehydrogenase kinase 2, and LHDA. Further analysis revealed that oxamate significantly reduced chondrocyte apoptosis in articular cartilage. Oxamate attenuates nociception, inflammation, cartilage degradation, and chondrocyte apoptosis and possibly attenuates glycolysis-related protein expression in ACLT-induced OA rats. The present findings will facilitate future research on LDHA inhibitors in prevention strategies for OA progression.

BACKGROUND: Although uncommon, available evidence suggests that pneumorrhachis (PR) with spontaneous pneumomediastinum (SPM) in adulthood is usually benign and self-limiting. This study aimed to review our experience and identify the risk factors of PR in pediatric patients with SPM. METHODS: Between September 2007 and September 2017, SPM in patients aged ≤18 years was retrospectively reviewed and clinical features and outcomes between SPM patients with and without PR were analyzed. RESULTS: In total, thirty consecutive occurrences of SPM in 29 patients were finally identified and classified into SPM (n = 24) and SPM plus PR (n = 6) groups. No significant differences in received interventional exams, prophylactic antibiotic administration or restriction of oral intake between the two groups were found. Both groups were treated with hospitalization predominantly; but the SPM plus PR group tended to have longer length of hospital stay (median 5.5 vs. 3 days, p = 0.08). PR was observed more frequently in patients with abnormal serum C-reactive protein (CRP) levels (>5 mg/L), identified predisposing factors, and those with more severe grade of SPM (p = 0.005, 0.001 and < 0.001, respectively). On multivariable regression analysis, the SPM plus PR group exhibited more predisposing factors than did the SPM group (coefficient: 0.514, standard error: 0.136, p < 0.001). All patients were successfully treated without morbidity and mortality. CONCLUSION: Although patients with pneumorrhachis retained a higher CRP level, more identified predisposing factors and prolonged inpatient care, conservative management without an extensive work-up would be an appropriate and favorable strategy in pediatrics with concurrent SPM and PR.

BACKGROUND: Simultaneous bilateral thoracoscopic lung resection (SBTLR) has been shown to be a feasible and efficacious approach for a wide range of pulmonary conditions. Our aim was to evaluate the impact of different procedures on surgical outcomes in patients receiving SBTLR. METHODS: Between 2012 and 2021, 207 patients with bilateral lung neoplasms who underwent SBTLR were retrospectively reviewed. Fifty-one patients received ipsilateral plus contralateral lobectomy or sublobectomy (lobar group), whilst 156 patients received bilateral sublobectomy (sublobar group). Propensity scores were calculated and matched. Perioperative and clinicopathologic outcomes were compared. RESULTS: The lobar group had a greater mean age (64.5 vs. 60.0 years, p = 0.008), longer operative time (254 vs. 205 min, p < 0.001), and more blood loss (74 vs. 46 ml, p < 0.001). The sublobar group had fewer complications (6.4 vs. 19.6%, p = 0.006), shorter hospital stay (4.8 vs. 7.4 days, p < 0.001), and lower hospital costs (p = 0.03). Among 50 pairs of matched groups, significant differences were found only in operative time, hospital stay, and costs. Maximum tumor size and pathological features differed significantly before and after matching (all p < 0.05), with the lobar group consistently demonstrating a larger main tumor (median, 2.5 cm) and a higher percentage of primary lung cancer (84%). Multivariate logistic regression analysis showed that a longer operative time was the factor associated with more complications (OR: 1.01; 95% CI 1.00-1.02, p = 0.002). CONCLUSIONS: With regard to SBTLR, our data suggests that sublobectomy may reduce the prolonged recovery, hospital costs, and complications incurred by lobectomy, without compromising oncological outcomes.

BACKGROUND: Pregnancy-related anxiety (PRA) is a distinct type of anxiety from general anxiety, affects many pregnant women, and is correlated with poor behavioral development in children. However, the mediation paths were unclear. METHODS: A total of 2032 mother-infant pairs from the Ma'anshan Birth Cohort were included in the current study. Maternal PRA was assessed in the second and third trimesters. Children's behavioral development was evaluated at the age of 18 months. In addition, information on parenting styles and breastfeeding methods was obtained at postpartum. Multivariate regression and structural equation modeling were used to examine the associations between maternal PRA and children's behavioral development. RESULTS: Significant intercorrelations were found between maternal PRA, the potential mediators (parenting styles and breastfeeding methods), and 18-month-old children's ASQ scores. Parenting styles played an intermediary role in the relationship between maternal PRA and children's behavioral development (ß = 0.030, 95 % confidence interval: 0.017-0.051), and the mediating effect accounted for 29.1 % of the total effect. However, breastfeeding methods did not mediate the link between PRA and children's behavior. LIMITATIONS: Depression and postpartum anxiety were not controlled for in our analysis, which left us unable to estimate the independent impact of PRA on children's behavior. CONCLUSIONS: Parenting rather than breastfeeding is the mediating factor of behavioral problems in children caused by PRA.

BACKGROUND: According to recent animal models for lung adenocarcinoma metastasis, cardiac function may be related to the clinical outcome. The aim of this study is to identify a predictable index for postoperative metastasis (POM) that is associated with cardiac function. METHODS: Two hundred and seven consecutive patients who underwent thoracoscopic resection for stage I lung adenocarcinoma were included. Disease-free survival (DFS), overall survival (OS), and patients' clinical and pathological characteristics were analyzed. RESULTS: Among the 207 patients, 17 cases demonstrated metastasis, 110 cases received a preoperative echocardiogram, and six cases had POM. Mitral valve peak A velocity, which is one of the left ventricular diastolic function parameters affected by BMI (MVPABMI), was associated with a negative factor for POM (hazard ratio (HR): 2.139, p = 0.019) and a poor 5-year DFS in the above median (100% vs. 87%, p = 0.014). The predictable rate increased from 30.7% to 75% when the MVPABMI was above the median = 3.15 in the solid subtype). CONCLUSIONS: MVPABMI is a novel index for POM prediction in early-stage lung adenocarcinoma. This is a pilot study and the first attempt at research to verify that the diastole and the BMI may be associated with POM in early-stage lung adenocarcinoma.
RESUMO
BACKGROUND: Resection is the current treatment of choice for resectable bilateral pulmonary metastases. This study aimed to compare the differences in outcomes between simultaneous bilateral open and video-assisted thoracic surgery (VATS) for pulmonary metastasectomy. METHODS: Forty-three patients underwent pulmonary metastasectomy through one-stage bilateral open thoracotomy (n = 16) and VATS (n = 27) between 2011 and 2020. Perioperative and oncological data were analyzed. RESULTS: The predominant primary tumor histology in both groups was colorectal cancer. The operative time, blood loss, and pain score on postoperative day 1 (POD1) were higher in the open group (p < 0.001, 0.009, and 0.03, respectively). No significant differences in pain score on POD2 and POD3, postoperative length of stay, or complications were found. Notably, numbers of the resected metastatic lung nodules were significantly greater in the open group (median number: 9.5 vs. 3, p < 0.001). Recurrence-free survival (RFS) and overall survival (OS) were comparable. The median RFS was 15 months (interquartile range [IQR], 6-22) in the open group and 18 months (IQR, 8-47) in the VATS group. The median OS was 28 months (IQR, 14-44) and 29 months (IQR, 15-54) in the open group and VATS group, respectively. CONCLUSION: One-stage bilateral pulmonary metastasectomy is safe and reduces medical expenditures in selected patients regardless of surgical approach. Although the open group harbored a greater number of metastatic foci, perioperative and oncological outcomes were similar to that of the VATS group.

BACKGROUND: The poor outcome of patients with lung squamous cell carcinoma (LUSC) highlights the importance of the identification of novel effective prognostic markers and therapeutic targets. Long noncoding RNAs (lncRNAs) have generally been considered to serve important roles in tumorigenesis and the development of various types of cancer, including LUSC. METHODS: Here, we aimed to investigate the role of LINC02323 in LUSC and its potential mechanisms by performing comprehensive bioinformatic analyses. RESULTS: LINC02323 was elevated and positively associated with unfavorable prognosis of LUSC patients. LINC02323 exerted oncogenic function by competitively binding to miR-1343-3p and miR-6783-3p, thereby upregulating L1CAM expression. Indeed, we also determined that LINC02323 could interact with the RNA-binding protein DDX3X, which regulates various stages of RNA expression and processing. CONCLUSION: Taken together, we identified that LINC02323 and its indirect target L1CAM can act as novel biomarkers for determining the prognosis of patients with LUSC and thus deserves further study.

Background: Although uniportal video-assisted thoracoscopic surgery (VATS) has been performed for a wide array of thoracic diseases, unsightliness and poor wound healing often occur, particularly when a chest drain is placed postoperatively. Different chest drain wound closure (CWC) methods have been introduced with the benefits of cosmesis and patient satisfaction. We aimed to describe our improved CWC technique in this setting and assess its efficacy. Methods: A total of consecutive 334 patients undergoing uniportal VATS pulmonary resection with single chest drain placement were investigated from 2016 to 2021. The techniques for CWC were classified into the conventional method (35 patients, group A), continuous suture with removal-free stitches (122 patients, group B), and continuous suture with removal-free barbed suture plus topical skin adhesives (177 patients, group C). Perioperative data and complications related to CWC were analyzed. Results: Group C had a significantly shorter operative time, postoperative hospital stay, and chest tube days than groups A and B (all p < 0.01). In terms of chest tube-related complications, there were no statistically significant differences in post-removal pneumothorax, subcutaneous emphysema, incisional effusion leakage, wound dehiscence, or infection. Overall, significant differences in scar scale scores were observed between the groups, where the ameliorated group C was superior to the conventional group A (p < 0.01). Conclusion: The improved CWC technique using continuous sutures with removal-free barbed sutures and topical skin adhesives is simple, safe, and effective. This may be a favorable CWC strategy when performing uniportal VATS, with enhanced patient satisfaction.
RESUMO
BACKGROUND: Chemoradiotherapy (CRT), which might affect the autonomic system, is the mainstay therapy for advanced esophageal squamous cell carcinoma (ESCC). Autonomic dysfunction has been found to possibly lead to cancer mortality in those with elevated resting heart rates (RHR). Skin sympathetic nerve activity (SKNA) is a new method of stimulating electrical signals in skin to evaluate autonomic function from sympathetic tone. In this study, we investigated the association between changes in RHR and autonomic function and ESCC mortality. METHODS: Thirty-nine stage II-IV ESCC patients receiving CRT between March 2019 and November 2020 were prospectively enrolled and carefully selected, followed up and received the same meticulous supportive care. Serial RHR was recorded every two weeks from before CRT to eight weeks after CRT and average SKNA were recorded before and four weeks after CRT. All-cause mortality was defined as primary outcome. RESULTS: We found the RHR of ESCC patients to be significantly elevated and peaking at four weeks after CRT (p < 0.001) and then to gradually decrease. Those with an elevated RHR above the cutoff level (18 beat-per-minute) at eight weeks after CRT had worse overall survival. In addition, those with higher baseline sympathetic tone (average SKNA ≥ 0.86 µV) also had poor outcome. CONCLUSIONS: Increased pre-treatment sympathetic tone and elevated RHR after CRT are alarm signs of poor ESCC outcome. Further exploration of the mechanisms underlying these associations could potentially lead to intervention strategies for reducing mortality. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, identifier: NCT03243448.

Congenital tracheoesophageal fistula (TEF) without esophageal atresia is usually diagnosed and treated in the neonatal period. It is uncommon to occur in adulthood. Conventional treatment of adult-onset TEF involves repair by either cervicotomy or thoracotomy. We reported the case of a 31-year-old male patient with clinical and radiographic evidence of congenital H-type TEF. Although this fistula was located at the level of the second thoracic vertebra, the repair of the anomaly was performed successfully using a thoracoscopic approach with the novel use of a polyglycolic acid sheet reinforcement.

BACKGROUND: Completion lobectomy (CL) after anatomical segmentectomy is technically challenging and rarely performed. Here, we aimed to report perioperative outcomes of a single center real-world CL data. METHODS: Seven patients who underwent CL after segmentectomy were retrospectively evaluated between 2015-2021. Additionally, 34 patients were included in the review based on relevant studies in the literature until March 2022. A total of 41 patients were finally analyzed and classified into groups, according to surgical approach (video-assisted thoracic surgery [VATS] and thoracotomy; 12 and 29 patients, respectively) or interval-to-CL following initial segmentectomy (≤8 weeks [short] and >8 weeks [long]; 11 and 30 patients, respectively). RESULTS: There were no significant differences in estimated blood loss, postoperative hospital stay, or complications between the predefined groups. However, a longer operative time was observed in the long interval-to-CL group than in the short interval-to-CL group (267 vs. 226 min, p = 0.02). The rate of severe hilar adhesions was higher in the thoracotomy versus VATS groups (72 vs. 42%, p = 0.06) and in the long versus short interval-to-CL groups (70 vs. 45%, p = 0.15). On multivariable logistic regression analysis of a subgroup (n = 30), completion lobectomy of upper lobes may be associated with severe hilar adhesions (p = 0.02, odds ratio: 13.98; 95% confidence interval [CI]: 1.36-143.71). CONCLUSION: Completion lobectomy after segmentectomy can be performed securely by either VATS or thoracotomy. Although the thoracotomy and long interval-to-CL groups retained a greater percentage of severe hilar adhesions, the perioperative outcomes were similar to those of VATS and short interval-to-CL groups, respectively.

There is a lack of data comparing postoperative pain after subxiphoid and intercostal video-assisted thoracoscopic surgery (VATS). Pain is an individual's subjective experience and, therefore, difficult to compare between different individuals subjected to either procedure. This study assessed reported pain at six postoperative time points in the same patients receiving both subxiphoid and intercostal incisions for thoracic disease. Data from 44 patients who received simultaneous combined intercostal and subxiphoid VATS were retrospectively analyzed from August 2019 to July 2021. All patients received the same length of subxiphoid and intercostal incisions with or without drain placements. A numerical pain rating scale was administered on postoperative days (POD)-1, POD-2, POD-Discharge, POD-30, POD-90, and POD-180. Bilateral uniportal VATS was performed in 11 patients, and unilateral multiportal VATS was performed in 33 patients. In the unilateral VATS group, there were no differences in pain reported for both incisions in the early postoperative period. However, in the bilateral VATS group, subxiphoid wounds resulted in significantly higher pain scores on POD-1, POD-2, and POD-Discharge (p = 0.0003, 0.001, and 0.03, respectively). Higher late (3 and 6 months) postoperative pain was associated with intercostal incisions in both groups, as previously reported, whereas higher early (day 1, 2, and discharge) postoperative pain was more associated with subxiphoid incisions than intercostal incisions in the bilateral VATS group.
