Comparative Study of Indocyanine Green Intravenous Injection and the Inflation-Deflation Method for Assessing Resection Margins in Segmentectomy for Lung Cancer: A Single-Center Retrospective Study. J Chest Surg 2024:jcs.24.008. [PMID: 38650484 DOI: 10.5090/jcs.24.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/11/2024] [Accepted: 02/29/2024] [Indexed: 04/25/2024] Open
Abstract
Background The inflation-deflation (ID) method has long been the standard for intraoperative margin assessment in segmentectomy. However, with advancements in vision technology, the use of near-infrared mapping with indocyanine green (ICG) has become increasingly common. This study was conducted to compare the perioperative outcomes and resection margins achieved using these methods. Methods This retrospective study included patients who underwent direct segmentectomy for clinical stage I lung cancer between January 2018 and September 2022. We compared perioperative factors, including bronchial and parenchymal resection margins, according to the margin assessment method and the type of segmentectomy performed. Since the ICG approach was adopted in April 2021, we also examined a recent subgroup of patients treated from then onward. Results A total of 319 segmentectomies were performed. ID and ICG were utilized for 261 (81.8%) and 58 (18.2%) patients, respectively. Following April 2021, 61 patients (51.3%) were treated with ID, while 58 (48.7%) received ICG. We observed no significant difference in resection margins between ID and ICG for bronchial (2.7 cm vs. 2.3 cm, p=0.07) or parenchymal (2.5 cm vs. 2.3 cm, p=0.46) margins. Additionally, the length of hospitalization and the complication rate were comparable between groups. Analysis of the recent subgroup confirmed these findings, showing no significant differences in resection margins (bronchial: 2.6 cm vs. 2.3 cm, p=0.25; parenchymal: 2.4 cm vs. 2.3 cm, p=0.75), length of hospitalization, or complication rate. Conclusion The perioperative outcomes and resection margins achieved using ID and ICG were comparable, suggesting that both methods can safely guide segmentectomy procedures.

Abstract
BACKGROUND This study was conducted to evaluate the mid-term outcomes of rapid-deployment aortic valve replacement (AVR) using Edwards Intuity. METHODS A total of 215 patients underwent rapid-deployment AVR using Edwards Intuity at our institution. The median follow-up duration was 22 months (interquartile range, 8-36). Primary outcomes were overall survival, cumulative incidence of cardiac death, and major adverse cardiac events. Secondary outcomes were early and 1-year hemodynamic performances of the bioprosthetic valve. RESULTS The mean age was 68.6 ± 10.5 years, and EuroSCORE II was 3.09 ± 4.5. The study population included 113 patients (52.6%) with bicuspid valves (24 patients with type 0 bicuspid valves), 20 patients (9.3%) with pure aortic regurgitation, and 3 patients (1.4%) with infective endocarditis. Isolated AVR was performed in 70 patients (32.4%) and concomitant procedures were performed in 146 patients (67.6%), including aorta surgery (42.3%) and mitral valve procedure (22.3%). Operative mortality was 2.8%. Complete atrioventricular block occurred in 12 patients, but most of them were transient and only 3 patients received permanent pacemaker implantation before discharge. Overall survival at 3 years was 92.3%. Early hemodynamic data showed mean pressure gradients of 15.5 ± 5.0 and 12.7 ± 4.2 mm Hg in the 19 and 21 mm valve, respectively. One-year hemodynamics were also excellent with mean pressure gradients of 14.7 ± 5.3 and 10.7 ± 3.6 mm Hg in the 19 and 21 mm valve, respectively. CONCLUSION Based on a real-world all-comers population, rapid-deployment AVR using Edwards Intuity could be performed for various indications, including bicuspid valve, pure aortic regurgitation, and infective endocarditis, and the clinical and hemodynamic outcomes were excellent.

Abstract
Congenital lung malformations (CLM) are most commonly treated with a pulmonary lobectomy. However, due to technological advancement, video-assisted thoracoscopic surgery (VATS) segmentectomy is becoming an attractive alternative to VATS lobectomy. This study aimed to evaluate the safety, feasibility, and efficacy of VATS segmentectomy as a lung parenchyma-saving strategy in children with CLM. A retrospective analysis was performed on 85 children, for whom VATS segmentectomy was tried for CLM between January 2010 and July 2020. We compared the surgical outcomes of VATS segmentectomy with the outcomes of 465 patients who underwent VATS lobectomy. Eighty-four patients received VATS segmentectomy and thoracotomy conversion was necessary for one patient for CLM. The mean age was 3.2 ± 2.5 (range 1.2-11.6) years. The mean operative time was 91.4 ± 35.6 (range 40-200) minutes. The median duration of chest tube drainage was 1 (range 1-21) day, and the median length of postoperative hospital stay was 4 (range 3-23) days. There were no postoperative mortality and postoperative complications developed in 7 patients (8.2%), including persistent air leakage in 6 patients (7.1%) and postoperative pneumonia in 1 patient (1.2%). The median follow-up period was 33.5 (interquartile range 31-57) months and there were no patients requiring re-intervention or reoperation during the follow-up period. In the VATS segmentectomy group, the persistent air leakage rate was higher than in the VATS lobectomy group (7.1 vs. 1.1%, p = 0.003). Otherwise, postoperative outcomes were comparable between the two groups. VATS segmentectomy in children with CLM is a technically feasible alternative to VATS lobectomy with acceptable early and mid-term outcomes. However, the persistent air-leakage rate was higher in VATS segmentectomy.

Pembrolizumab monotherapy versus chemotherapy in platinum-pretreated, recurrent or metastatic nasopharyngeal cancer (KEYNOTE-122): an open-label, randomized, phase III trial. Ann Oncol 2023; 34:251-261. [PMID: 36535566 DOI: 10.1016/j.annonc.2022.12.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 11/22/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Pembrolizumab previously demonstrated robust antitumor activity and manageable safety in a phase Ib study of patients with heavily pretreated, programmed death ligand 1 (PD-L1)-positive, recurrent or metastatic nasopharyngeal carcinoma (NPC). The phase III KEYNOTE-122 study was conducted to further evaluate pembrolizumab versus chemotherapy in patients with platinum-pretreated, recurrent and/or metastatic NPC. Final analysis results are presented. PATIENTS AND METHODS KEYNOTE-122 was an open-label, randomized study conducted at 29 sites, globally. Participants with platinum-pretreated recurrent and/or metastatic NPC were randomly assigned (1 : 1) to pembrolizumab or chemotherapy with capecitabine, gemcitabine, or docetaxel. Randomization was stratified by liver metastasis (present versus absent). The primary endpoint was overall survival (OS), analyzed in the intention-to-treat population using the stratified log-rank test (superiority threshold, one-sided P = 0.0187). Safety was assessed in the as-treated population. RESULTS Between 5 May 2016 and 28 May 2018, 233 participants were randomly assigned to treatment (pembrolizumab, n = 117; chemotherapy, n = 116); Most participants (86.7%) received study treatment in the second-line or later setting. Median time from randomization to data cut-off (30 November 2020) was 45.1 months (interquartile range, 39.0-48.8 months). Median OS was 17.2 months [95% confidence interval (CI) 11.7-22.9 months] with pembrolizumab and 15.3 months (95% CI 10.9-18.1 months) with chemotherapy [hazard ratio, 0.90 (95% CI 0.67-1.19; P = 0.2262)]. Grade 3-5 treatment-related adverse events occurred in 12 of 116 participants (10.3%) with pembrolizumab and 49 of 112 participants (43.8%) with chemotherapy. Three treatment-related deaths occurred: 1 participant (0.9%) with pembrolizumab (pneumonitis) and 2 (1.8%) with chemotherapy (pneumonia, intracranial hemorrhage). CONCLUSION Pembrolizumab did not significantly improve OS compared with chemotherapy in participants with platinum-pretreated recurrent and/or metastatic NPC but did have manageable safety and a lower incidence of treatment-related adverse events.

Abstract
Dispersion engineering is a powerful and versatile tool that can vary the speed of light signals and induce negative-mass effects in the dynamics of particles and quasiparticles. Here, we show that dissipative coupling between bound electron-hole pairs (excitons) and photons in an optical microcavity can lead to the formation of exciton polaritons with an inverted dispersion of the lower polariton branch and hence, a negative mass. We perform direct measurements of the anomalous dispersion in atomically thin (monolayer) WS2 crystals embedded in planar microcavities and demonstrate that the propagation direction of the negative-mass polaritons is opposite to their momentum. Our study introduces the concept of non-Hermitian dispersion engineering for exciton polaritons and opens a pathway for realising new phases of quantum matter in a solid state.

Abstract
Background Robot-assisted repair of atrial septal defect (ASD) can be performed under either beating-heart or non-beating-heart conditions. However, the risk of cerebral air embolism (i.e., stroke) is a concern in the beating-heart approach. This study aimed to compare the outcomes of beating- and non-beating-heart approaches in robot-assisted ASD repair. Methods From 2010 to 2019, a total of 45 patients (mean age, 43.4±14.6 years; range, 19–79 years) underwent ASD repair using the da Vinci robotic surgical system. Twenty-seven of these cases were performed on a beating heart (beating-heart group, n=27) and the other cases were performed on an arrested or fibrillating heart (non-beating-heart group, n=18). Cardiopulmonary bypass (CPB) was achieved via cannulation of the femoral vessels and the right internal jugular vein in all patients. Results Complete ASD closure was verified using intraoperative transesophageal echocardiography in all patients. Conversion to open surgery was not performed in any cases, and there were no major complications. All patients recovered from anesthesia without any immediate postoperative neurologic symptoms. In a subgroup analysis of isolated ASD patch repair (beating-heart group n=22 vs. non-beating-heart group n=5), the operation time and CPB time were shorter in the beating-heart group (234±38 vs. 253±29 minutes, p=0.133 and 113±28 vs. 143±29 minutes, p=0.034, respectively). Conclusion Robot-assisted ASD repair can be safely performed with the beating-heart approach. No additional risk in terms of cerebral embolism was found in the beating-heart group.

Abstract
A 2-year-old mixed breed dog presented with a 1-year history of crust and erosion on the nasal planum. Because histopathological examination revealed ruptured intraepidermal pustules and superficial dermal inflammation, the dog was diagnosed with pemphigus foliaceus. Human intravenous immunoglobulin was administered in two consecutive doses of 0.5 g/kg/day due to poor therapeutic response to previous immunosuppressive therapy. From Day 3 after the first dose of human intravenous immunoglobulin, tachypnoea, pale mucous membrane, haemoglobinuria and haemoglobinemia were observed, thus confirming haemolytic anaemia. Other drug-induced haemolytic anaemias were excluded because no additional drugs had been administered before the haemolysis occurred. Immune-mediated haemolytic anaemia was also excluded because the direct antiglobulin test was negative. Two transfusions were performed, and haemolysis was not observed from Day 4 of haemolytic anaemia onset. In conclusion, human intravenous immunoglobulin-induced haemolytic anaemia should be considered in dogs that develop haemolysis following the administration of human intravenous immunoglobulin.

Abstract
Nanoscale engineering of carbon materials is immensely demanded in various scientific areas. We present highly ordered nitrogen-doped carbon nanowire arrays via block copolymer (BCP) self-assembly under an electric field. Large dielectric constant difference between distinct polymer blocks offers rapid alignment of PMMA-b-PAN self-assembled nanodomains under an electric field. Lithographic patterning of the graphene electrode as well as straightforward thermal carbonization of the PAN block creates well-aligned carbon nanowire device structures. Diverse carbon nanopatterns including radial and curved arrays can be readily assembled by the modification of electrode shapes. Our carbon nanopatterns bear a nitrogen content over 26%, highly desirable for NO2 sensing, as the nitrogen element acts as adsorption sites for NO2 molecules. Aligned carbon nanowire arrays exhibits a 6-fold enhancement of NO2 sensitivity from a randomly aligned counterpart. Taking advantage of well-established benefits from device-oriented BCP nanopatterning, our approach proposes a viable route to highly ordered carbon nanostructures compatible to next-generation device architectures.

Abstract
Although subjective global assessment (SGA) is a widely used representative tool for nutritional investigations even among dialysis patients, no studies have examined gender-specific differences in the ability of SGA to predict mortality in hemodialysis (HD) patients. A total of 2,798 dialysis patients were enrolled from clinical research center for end-stage renal disease (CRC for ESRD) between 2009 and 2015. The cohort was divided into two groups based on nutritional status as evaluated by SGA: 'good nutrition' and 'mild to severe malnutrition'. Multivariate Cox proportional regression analyses were performed to investigate gender-specific differences in SGA for mortality among incident and prevalent HD patients. 'Mild to severe malnutrition' was significantly correlated with increased mortality compared with 'good nutrition' for all HD, incident and prevalent HD patients. Compared with 'good nutrition', 'mild to severe malnutrition' was also more significantly associated with increased mortality in male patients in the incident and prevalent HD groups. However, no significant associations between nutritional status evaluated by SGA and mortality were observed for female patients. SGA of HD patients can be useful for predicting mortality, especially in male HD patients. However, SGA alone might not reflect adverse outcomes in female patients.

Abstract
Although subjective global assessment (SGA) is a widely used tool for nutritional investigation, the scores are dependent on the inspectors' subjective opinions, and there are only few studies that directly assessed the usefulness of SGA and modified SGA in incident peritoneal dialysis (PD) patients. A total of 365 incident PD patients between 2009 and 2015 were enrolled and measured with SGA and calculated using serum albumin and total iron binding capacity (TIBC) levels for weighted SGA. Cox analyses were performed to delineate the association between SGA or weighted SGA and all-cause mortality, and a receiver-operating characteristic was conducted to reveal the additional benefit of weighted SGA on predicting adverse clinical outcomes. The Kaplan-Meier curve showed that the cumulative survival rate in patients with "Good nutrition" (G1) was significantly higher compared to those with "Mild to severe malnutrition" (G2). G2 was significantly associated with an increase in the mortality even after adjusting for several covariates compared with G1. Moreover, a 1-unit increase in weighted SGA was also significantly correlated with mortality after adjustment of the same covariates, while G2 was not significantly associated with an increase in the mortality among young-aged (under 65 years) groups. Meanwhile, a 1-unit increase in weighted SGA was significantly related to an increase in mortality in all the subgroup analyses. Furthermore, the AUCs of weighted SGAs in all groups were significantly increased compared with those of SGA alone. In conclusions, the evaluation of nutritional status based on SGA in incident PD patients might be useful for predicting mortality. However, weighted SGA with serum albumin and TIBC can provide additional predictive power for mortality compared with SGA alone in incident PD patients.

Abstract
8057 Background: Statins reduce not only serum cholesterol levels but also mevalonate synthesis by inhibiting HMG-CoA reductase. Mevalonate is a precursor of several cellular major products including dolichol, geranylpyrophosphate (GPP) and farnesyl-pyrophosphate (FPP). Dolichol has a stimulatory effect on DNA synthesis and is linked to several tumor cell proteins. GPP and FPP cause isoprenylation of Ras and Rho those regulate signal transduction of several membrane receptors crucial for cell proliferation, differentiation, and apoptosis, which result in resistance to gefitinib. Thus depletion of mevalonate metabolites may enhance gefitinib activity in NSCLC. This study compared gefitinib alone with gefitinib plus simvastatin in patients with recurrent NSCLC after at least one chemotherapy. Methods: Between May 2006 and September 2008, 107 patients (51% male, 74% adenocarcinoma, 50% never-smoker, 54% more than two prior regimens) were randomly assigned to gefitinib alone (250 mg/d orally, n=53) or gefitinib plus simvastatin (250mg/d and 40 mg/d orally, respectively, n=54). A cycle was considered as 4 weeks of treatment. Therapy was continued until disease progression or intolerable toxicities. The primary end point was to assess response rate. Secondary end points included time to progression and survival. Median follow-up was 10.1 months. Results: Efficacy was similar for gefitinib and gefitinib plus simvastatin groups. Objective tumor response rates (RR) were 31.5% (95% CI, 19.1 to 43.9) and 32.1% (95% CI, 19.5 to 44.7); median PFS were 1.9 and 2.0 months; and median OS were 9.5 and 12.7 months, respectively. In subgroup analysis, gefitinib plus simvastatin showed a trend for higher RR than gefitinib alone in non-adenocarcinoma group (38.5% vs. 7.7%, p=0.08). Adverse events at both arms were generally mild (grade 1 or 2) and consisted mainly of skin reactions. Conclusions: Gefitinib combined with simvastatin did not improved efficacy compared to gefitinib alone in this unselected patient population, but showed a trend for higher efficacy in non-adenocarcinoma patients. Although it is preliminary, gefitinib combined with simvastatin showed slightly increased OS. Updated survival data will be presented. No significant financial relationships to disclose.

Combining galiximab with the chemotherapeutic agents fludarabine or doxorubicin improves efficacy in animal models of lymphoma. J Clin Oncol 2007.

Abstract
3040 Background: Galiximab, a primatized monoclonal antibody that binds with high affinity to CD80 and mediates antibody- dependent, cell-mediated cytotoxicity in vitro, is currently under investigation for the treatment of follicular non-Hodgkin’s lymphoma (NHL). In a phase I/II monotherapy study, galiximab produced an overall response rate of 11%, and tumor reductions were observed in 46% of patients. Initial clinical trials also demonstrate that galiximab is well tolerated and suggest that combining galiximab with rituximab (anti-CD20) provides clinical benefit. These results are consistent with preclinical studies in murine lymphoma xenograft model systems, which demonstrate the superiority of combination therapy. Methods: To further define the therapeutic potential of galiximab, the Raji subcutaneous and the SKW disseminated lymphoma murine xenograft models were used to define the in vivo efficacy of galiximab alone or in combination with fludarabine or doxorubicin. Similar studies were performed with rituximab. Results: In the Raji model, both galiximab and rituximab exhibited maximal inhibition of the growth of preestablished (150-mg) tumors at a dose of 3 mg/kg/wk. Interestingly, higher doses of galiximab (but not rituximab) showed reduced inhibition. Galiximab (3 mg/kg/wk) inhibited tumor growth alone (P<0.0001 vs. control) and showed significantly enhanced activity when combined with fludarabine (50 or 100 mg/kg daily for 5 days; P<0.0002 vs. galiximab alone and P<0.003 vs. fludarabine alone). Similar results were observed with rituximab. In the SKW model, treatment with galiximab (5 mg/kg/wk for 6 doses) significantly enhanced survival compared with a control (P<0.0001) or doxorubicin (2.5 mg/kg/day for 3 doses; P<0.0001). Studies combining fludarabine or doxorubicin with both galiximab and rituximab are ongoing. Conclusions: Studies in animal models of lymphoma indicate that galiximab may provide clinical benefit when used in combination with chemotherapeutic agents such as fludarabine and doxorubicin, and provide a rationale for the investigation of these novel chemoimmunotherapy combinations in clinical trials. No significant financial relationships to disclose.

Abstract
We report a 54-year-old man who had adrenal cortical carcinoma initially manifested as features of overwhelming disseminated intravascular coagulation (DIC). In the initial diagnostic work-up, an adrenal mass was detected with venous thrombi in the abdominal imaging study, but the radiologic diagnosis was a hematoma arising from the adrenal gland and a biopsy was not possible due to a bleeding tendency. A lot of platelets and plasma products were transfused, but the bleeding tendency and other DIC features persisted. Finally, he expired because of newly developed massive pulmonary thromboembolism. To our knowledge, this is the first reported case of adrenal cortical carcinoma complicated with bleeding tendency caused by DIC as an initial manifestation. This suggests that adrenal cortical carcinoma should be considered in a patient with an adrenal mass and DIC features.

Alcohol, tobacco and breast cancer--collaborative reanalysis of individual data from 53 epidemiological studies, including 58,515 women with breast cancer and 95,067 women without the disease. Br J Cancer 2002; 87:1234-45. [PMID: 12439712 PMCID: PMC2562507 DOI: 10.1038/sj.bjc.6600596] [Citation(s) in RCA: 675] [Impact Index Per Article: 30.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2002] [Revised: 08/08/2002] [Accepted: 08/23/2002] [Indexed: 12/11/2022] Open
Abstract
Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58,515 women with invasive breast cancer and 95,067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19-1.45, P<0.00001) for an intake of 35-44 g per day alcohol, and 1.46 (1.33-1.61, P<0.00001) for >/=45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P<0.00001) for each additional 10 g per day intake of alcohol, i.e. for each extra unit or drink of alcohol consumed on a daily basis. This increase was the same in ever-smokers and never-smokers (7.1% per 10 g per day, P<0.00001, in each group). By contrast, the relationship between smoking and breast cancer was substantially confounded by the effect of alcohol. When analyses were restricted to 22 255 women with breast cancer and 40 832 controls who reported drinking no alcohol, smoking was not associated with breast cancer (compared to never-smokers, relative risk for ever-smokers=1.03, 95% CI 0.98-1.07, and for current smokers=0.99, 0.92-1.05). The results for alcohol and for tobacco did not vary substantially across studies, study designs, or according to 15 personal characteristics of the women; nor were the findings materially confounded by any of these factors. If the observed relationship for alcohol is causal, these results suggest that about 4% of the breast cancers in developed countries are attributable to alcohol. In developing countries, where alcohol consumption among controls averaged only 0.4 g per day, alcohol would have a negligible effect on the incidence of breast cancer. In conclusion, smoking has little or no independent effect on the risk of developing breast cancer; the effect of alcohol on breast cancer needs to be interpreted in the context of its beneficial effects, in moderation, on cardiovascular disease and its harmful effects on cirrhosis and cancers of the mouth, larynx, oesophagus and liver.

Abstract
Although it is impossible to manufacture identical columns for use in a simulated moving bed (SMB) process, theoretical studies assume that all the columns in an SMB unit have identical characteristics. In practice, calculations in modeling and optimization studies are made with the average values of each column parameter set. In this report, the effects on SMB process performance caused by column-to-column fluctuations of the parameters are discussed. As a first step, we show how the differences in porosity of the columns may be taken into account with a revised set of separation conditions. Reductions in the purity of the extract and the raffinate streams are quantitatively related to the column-to-column fluctuations of the retention times of the two components arising from these porosity differences. For the sake of simplicity, the discussion first addresses the case of a four-column SMB operating under linear conditions. Then, the scope is extended to the cases of SMB units incorporating several columns in each section and to SMB units operating under nonlinear conditions.

Abstract
From January 1995 through July 1998, we investigated the occurrence of Cyclospora cayetanensis infection associated with gastrointestinal illness or diarrhea in foreign residents and natives of West Java, Indonesia. We found that C. cayetanensis was the main protozoal cause of gastrointestinal illness and diarrhea in adult foreign residents during the wet season. The parasite rarely caused illness in the indigenous population or in children.
