Abstract:
ABSTRACT Objective: Conventional bronchoscopy has a low diagnostic yield for peripheral pulmonary lesions. Radial-probe EBUS employs a rotating ultrasound transducer at the end of a probe that is passed through the working channel of the bronchoscope. Radial-probe EBUS facilitates the localization of peripheral pulmonary nodules, thus increasing the diagnostic yield. The objective of this study was to present our initial experience using radial-probe EBUS in the diagnosis of peripheral pulmonary lesions at a tertiary hospital. Methods: We conducted a retrospective analysis of 54 patients who underwent radial-probe EBUS-guided bronchoscopy for the investigation of pulmonary nodules or masses between February of 2012 and September of 2013. Radial-probe EBUS was performed with a flexible 20-MHz probe, which was passed through the working channel of the bronchoscope and advanced through the bronchus to the target lesion. For localization of the lesion and for collection procedures (bronchial brushing, transbronchial needle aspiration, and transbronchial biopsy), we used fluoroscopy. Results: Radial-probe EBUS identified 39 nodules (mean diameter, 1.9 ± 0.7 cm) and 19 masses (mean diameter, 4.1 ± 0.9 cm). The overall sensitivity of the method was 66.7% (79.5% and 25.0%, respectively, for lesions that were visible and not visible by radial-probe EBUS). Among the lesions that were visible by radial-probe EBUS, the sensitivity was 91.7% for masses and 74.1% for nodules. The complications were pneumothorax (in 3.7%) and bronchial bleeding, which was controlled bronchoscopically (in 9.3%). Conclusions: Radial-probe EBUS shows a good safety profile, a low complication rate, and high sensitivity for the diagnosis of peripheral pulmonary lesions.

Abstract:
The next diagnostic step in cases of indeterminate radial probe endobronchial ultrasound (radial EBUS)-guided biopsy results remains uncertain. This study aimed to identify risk factors for malignancy based on clinical findings, chest computed tomography (CT), and radial EBUS images, and to estimate the risk of malignancy in lung nodules that showed indeterminate radial EBUS-guided biopsy results by constructing a nomogram. This retrospective study included 157 patients with indeterminate results on an initial radial EBUS biopsy performed at the Samsung Medical Center from January 2017 to December 2018, but with a definitive final diagnosis. Medical records, chest CT, radial EBUS images, and the final diagnoses were reviewed. Patients were randomly divided into training and validation sets. Factors related to malignancy were identified through logistic regression analysis, and a nomogram was constructed using the training set and subsequently applied to the validation set. Six factors in univariable and multivariable analyses, including upper lobe location, spiculation, satellite nodules, echogenicity, presence of dots or linear arcs, and patency of vessels and bronchi predicted malignancy. A nomogram was constructed based on these predictors. The area under the curve (AUC) value of the nomogram was 0.858 using the chest CT factors, which improved to 0.952 when radial EBUS factors were added. The calibration curve showed good agreement between the actual and nomogram-predicted malignancy outcomes. The utility of radial EBUS images for revealing risk factors of malignancy was confirmed. Furthermore, our nomogram was able to predict the probability of malignancy in lung nodules with indeterminate radial EBUS-guided biopsy results.

Abstract:
Radial endobronchial ultrasound (R-EBUS) is a useful tool for precise localisation of peripheral pulmonary lesions, but there have been no detailed reports about the use of R-EBUS images for ground-glass opacity (GGO).The R-EBUS images of 116 patients with GGO, who were diagnosed as having adenocarcinoma by R-EBUS with a guide sheath (EBUS-GS), were compared with the respective chest computed tomography findings. In 103 patients, R-EBUS images were correlated with the histological surgical specimens.R-EBUS images of GGO were identified based on the internal structure of the lesion and classified into two groups. Blizzard showed an enlarged, diffuse hyperintense acoustic shadow. Mixed blizzard showed a combination of blizzard and some diffuse heterogeneity with several hyperechoic dots and vessels. All pure GGO lesions (nine out of nine) were blizzard on R-EBUS. For part-solid GGOs, the percentage of mixed blizzard was inversely related to the amount of the GGO component. Histological findings from surgery revealed that all blizzard lesions were on the spectrum of adenocarcinoma in situ to well differentiated adenocarcinoma while majority (33 out of 64) of mixed blizzard lesions were moderately to poorly differentiated adenocarcinoma.R-EBUS types are important to locate GGOs prior to transbronchial sampling with EBUS-GS.

Abstract:
Background: The diagnosis of organizing pneumonia (OP) often requires histological confirmation. The aim of this retrospective study was to evaluate the diagnostic yield and complication rate of radial endobronchial ultrasound (r-EBUS) for OP. Methods: All patients who had r-EBUS as a first diagnostic procedure for a peripheral pulmonary lesion at Rouen University Hospital, France, between April 2008 and December 2020 were included. Cases without a final diagnosis of OP or follow-up were excluded. Patients, lesions, and r-EBUS characteristics were retrospectively analyzed. Results: 2735 r-EBUS procedures were performed, and 33 cases with final OP could be analyzed. Procedures were performed under local anesthesia in 28/33 cases (85%). Among the 33 final OP cases, 17 were considered cryptogenic, and 16 secondary. The lesions were patchy alveolar opacities in 23 cases (70%), masses or pulmonary nodules in 8 cases (24%), and diffuse infiltrative opacities in 2 cases (6%). A bronchus sign on CT scan was found in all cases. In 22 cases (67%), a histopathological diagnosis was obtained from the r-EBUS samples. In 4 cases (12%), histopathological diagnosis was made by surgery, and in 7 cases (21%) the diagnosis was made based on clinical, radiological, and evolution features. An ultrasound image was found in 100% (22/22) of cases in the r-EBUS positive (r-EBUS+) group vs. 60% (6/10) in the r-EBUS negative (r-EBUS-) group, respectively (p < 0.002). The diagnostic yield of r-EBUS for OP was 67% and increased to 79% (22/28) when an ultrasound image was obtained. The median time between CT scan and r-EBUS procedure was 14 days (3–94): 11.5 days in the r-EBUS+ group and 22 days in the r-EBUS- group (p < 0.0001). No severe complications were reported. Conclusion: r-EBUS, when performed shortly after a CT scan showing a bronchus sign, is an efficient and safe technique for OP diagnosis.

Abstract:
Objective. We design a prospective control study on the utilization of transbronchial cryobiopsy guided by EBUS-GS (EBUS-GS-TBCB) to diagnose PPLs. Methods. PPLs were defined as pulmonary nodules or masses with a diameter from 10 mm to 50 mm. PPLs were randomly divided into group EBUS-GS-TBCB and transbronchial biopsy by forceps guided under EBUS-GS (EBUS-GS-TBB). Results. 28 cases were involved in group EBUS-GS-TBCB and 31 cases were in group EBUS-GS-TBB. The mean sizes of PPLs were 30.23 ± 11.10 mm in group EBUS-GS-TBCB and 28.69 ± 8.62 mm in group EBUS-GS-TBB (t = 0.600, p = 0.551 ). The diagnostic yields of EBUS-GS-TBCB and EBUS-GS-TBB were 75% and 64.52% respectively, and the difference between the two groups was not significant (χ2 value = 0.137, p = 0.711 ). If only the first specimen was taken into account, the diagnostic yields from EBUS-GS-TBCB and EBUS-GS-TBB were 64.29% (18/28 cases) and 35.48% (11/31 cases), respectively. The difference was statistically significant by Fisher’s Exact Test (χ2 value = 4.883, p = 0.038 ). The total incidence rates of bleeding were 21.43% and 6.45%, respectively, in groups EBUS-GS-TBCB and EBUS-GS-TBB. The total incidence rates of pneumothorax were 7.14% and 0, respectively, in groups EBUS-GS-TBCB and EBUS-GS-TBB. Conclusion. The diagnostic yield of EBUS-GS-TBCB was slightly higher than that of EBUS-GS-TBB for the diagnosis of PPLs. EBUS-GS-TBCB might be useful if only the first sample was taken into account.

Abstract:
Background Bronchoscopy using radial probe endobronchial ultrasound (EBUS) is performed when a peripheral lung lesion (PLL) is suspected to be malignant. However, pulmonary tuberculosis is diagnosed in some patients, and healthcare workers could therefore be exposed to tuberculosis if sufficient precautions are not taken. In this study, we examined the proportion of and factors associated with unexpected exposure to Mycobacterium tuberculosis during bronchoscopy using radial probe EBUS. Methods This retrospective study included 970 patients who received bronchoscopy using radial probe EBUS between December 2015 and November 2018. Clinical, histological, radiological, and microbiological data were reviewed. Results Pulmonary tuberculosis was diagnosed in 31 patients (3.2%) during bronchoscopy using radial probe EBUS. Patients with a lower age were significantly more likely to be diagnosed with tuberculosis than elderly patients (odds ratio [OR], 0.951; 95% confidence interval [CI], 0.924–0.978; P = 0.001). Among the various CT findings, a low HUs difference between pre- and post-enhanced CT (OR, 0.976; 95% CI, 0.955–0.996; P = 0.022), the presence of concentric cavitation (OR, 5.211; 95% CI, 1.447–18.759; P = 0.012), and the presence of satellite centrilobular nodules (OR, 22.925; 95% CI, 10.556–49.785; P < 0.001) were independently associated with diagnosis of tuberculosis. Conclusions The proportion of unexpected exposure to Mycobacterium tuberculosis during bronchoscopy using radial probe EBUS was 3.2%. A higher risk was independently associated with a younger age and CT findings of a small difference in HUs between pre- and post-enhancement images, concentric cavitation, and the presence of a satellite centrilobular nodule.

Abstract:
BackgroundRadial endobronchial ultrasonography (R-EBUS) has been used in conjunction with transbronchial lung cryobiopsy (TBLC) to diagnose diffuse parenchymal lung disease (DPLD) and to decrease the risk of bleeding complications. The diagnostic utility of different R-EBUS signs, however, remains unknown.ObjectivesThis study aimed to determine whether different R-EBUS signs could be used to more accurately diagnose DPLD and whether bronchial bleeding could be prevented with use of R-EBUS during TBLC.MethodEighty-seven patients with DPLD were included in this multicentre prospective study, with 49 patients undergoing R-EBUS. R-EBUS signals were characterised as displaying either dense or blizzard signs. Pathological confidence of specimens obtained from TBLC was compared between patients with dense versus blizzard signs, and severity of bronchial bleeding was determined based on whether R-EBUS was performed or not.ResultsAll patients with dense signs on R-EBUS showed consolidation on high-resolution CT (HRCT) imaging. Pathological confidence of lung specimens was significantly higher in patients with dense signs versus those with blizzard signs (p<0.01) and versus those who did not undergo R-EBUS (p<0.05). Patients who underwent TBLC with R-EBUS were more likely to experience no or mild bronchial bleeding than patients who did not undergo R-EBUS (p<0.01), with shorter procedure times (p<0.01).ConclusionsThe dense R-EBUS sign corresponded with consolidation on HRCT. High-quality lung specimens may be obtainable when the dense sign is observed on R-EBUS, and R-EBUS combined with TBLC may reduce risk of bronchial bleeding and shorten procedure times.

Abstract:
<b><i>Background:</i></b> The diagnostic yield of peripheral pulmonary lesions (PPLs) using radial endobronchial ultrasound (EBUS) remains challenging without navigation systems. Cone-beam computed tomography-derived augmented fluoroscopy (CBCT-AF) represents a recently developed technique, and its clinical utility remains to be investigated. <b><i>Objectives:</i></b> The aim of this study was to investigate the diagnostic yield of transbronchial biopsy (TBB) using a combination of CBCT-AF and radial EBUS. <b><i>Methods:</i></b> We recruited consecutive patients with PPLs who underwent radial EBUS-guided TBB, with or without AF, between October 2018 and July 2019. Following propensity score 1:1 matching, we recorded the procedure-related data and measured their efficacy and safety. <b><i>Results:</i></b> While 72 patients received EBUS-plus-AF, 235 patients received EBUS only. We included 53 paired patients following propensity score matching. The median size of lesions was 2.8 and 2.9 cm in the EBUS-plus-AF group and EBUS-only group, respectively. Diagnostic yield was higher in the former group (75.5 vs. 52.8%; <i>p</i> = 0.015). The diagnostic yield for the EBUS-plus-AF group was significantly higher for lesions ≤30 mm (73.5 vs. 36.1%; <i>p</i> = 0.002). Moreover, there was no significant difference in the complication rates (3.8 vs. 5.7%; <i>p</i> = 1.000). Twenty-four nodules (45.3%) were invisible by fluoroscopy in the EBUS-plus-AF group. All of them were identifiable on CBCT images and successfully annotated for AF. The mean radiation dose of total procedure, CBCT, and fluoroscopy was 19.59, 16.4, and 3.17 Gy cm<sup>2</sup>, respectively. <b><i>Conclusions:</i></b> TBB using a combination of CBCT-AF and EBUS resulted in a satisfactory diagnostic yield and safety.

Abstract:
Lung cancer is a leading cause of cancer-related deaths worldwide. This is no different in Australia where it is the main cause of cancer-related mortality, and the fifth most commonly cancer diagnosed in Australians. The recent National Lung Screening Trial demonstrated an improvement in mortality when patients deemed high risk for lung cancer underwent annual screening with low dose computed tomography imaging. Nearly 25% of participants were shown to have imaging suspicious for lung cancer. In light of these results, and with the possibility of increased uptake of screening, it is very likely that the incidence of identified peripheral pulmonary lesions (PPL) will only continue to rise. In evaluating PPLs, standard bronchoscopic investigation involves obtaining transbronchial forceps biopsies (TB-FB). However TBFB has variable diagnostic sensitivity, influenced by factors such as lesion size and position. The introduction of radial endobronchial ultrasound (RP-EBUS) has helped improve diagnostic yields further. Ultrasound images obtained by the miniprobe reflect the underlying structure of the peripheral lesion being examined and RPEBUS is now a well-established technique in the evaluation of PPLs. The overall aim of this thesis was to examine innovative bronchoscopic techniques which could further aid diagnostic yield in investigating PPLs. Methods (i) Radial Endobronchial Ultrasound Greyscale Texture Analysis Using Whole-Lesion Analysis Can Characterise Benign and Malignant Lesions without Region-of-Interest Selection Bias Custom software was developed to analyse RP-EBUS images based on first and second order greyscale texture features. Unconstrained ROIs were mapped onto lesions. Features from expert and nonexpert defined ROIs were compared, as were results of image analysis to tissue histology. (ii) Radial Endobronchial Ultrasound with Transbronchial Cryobiopsy versus Radial EBUS alone for the Diagnosis of Peripheral Pulmonary Lesions Prospective, single-centre randomised controlled trials of patients with PPLs. Patients were randomised to receive either one transbronchial cryobiopsy (TB-CB) sample, or 5 TB-FB samples. Results (i) Greyscale texture analysis of RP-EBUS images using unconstrained regions of interest (ROIs) demonstrated 5 features which were significantly different between benign and malignant lesions. Highest positive predictive values were associated with maximal and range of pixel intensities. No significant differences were seen between expert and non-expert-defined ROIs. (ii) 28 lesions were evaluated with overall diagnostic yield 76.7%. Diagnostic yields of TB-CB and TB-FB were 91.7% and 68.8% respectively (p=0.14). Median size of TB-CB was 7.0mm compared to 2.55mm (p<0.0001). There were no major complications with either technique. Conclusion Timely diagnosis of PPLs is critical to enable disease staging and to guide initiation of appropriate definitive treatment. Greyscale image analysis and texture analysis using the whole RP-EBUS image as a ROI can assist in distinguishing between malignant and benign lesions. This is a potentially valuable additional clinical tool in the diagnosis of peripheral lesions. However further validation is required. Cryotherapy has provided an alternative method of obtaining transbronchial biopsies (TBBs). Not only does it provide significantly larger biopsy sample, which is advantageous for further immunohistochemical and molecular analysis, but it also could be superior in diagnosing lesions which are not easily accessible by TB-FB.

Abstract:
During the first half of the twentieth century, Mexican Chicago was shaped by the ebbs and flows of revolutionary politics. Initially, the liberals, radicals, and conservatives all defined themselves as patriotic Mexican citizens. The Calles and Cardenas presidencies reinforced the nationalism of the liberals and radicals, while these presidencies and their policies repulsed the traditionalists from Mexico. As traditionalists distanced themselves from postrevolutionary Mexico, they offered Mexican Catholics a deterritorialized brand of mexicanidad that characterized Mexicans as a supranational people. U.S. deportation campaigns only underscored the ways Mexican citizenship could cost traditionalists their Catholic communities. In the end, the liberals and radicals were simply too disenchanted with the United States to become U.S. citizens, while Mexican radicalism and American nativism convinced traditionalists that it was in their best interest to become Americans.

Abstract:
Achieving widespread access by all European citizens to new services and advanced applications of the information society is one of the crucial goals of the European Union’s (EU) strategic framework for the future. Towards realizing this primary target, multiple access platforms are expected to become available, using different access methods for delivery of services (and of related digital content) to a wide variety of end-user terminals, thus creating an “always-on” and properly “converged” technological and business environment, all able to support and to promote innovation and growth (Commission of the European Communities, 2005). The result will be a “complementarity” of services and markets in an increasingly sophisticated way. Economic and technology choices imply certain networks for certain service options. As these networks become more powerful, the temptation is to adapt certain characteristics of the network technology to make it suitable for modern services. The challenge is to build “bridges” or “links” between the different convergent technologies without undermining the business models on which they are built. In such a context, converging technology means that innovative systems and services are under development with inputs, contributions, and traditions from multiple industries, including telecommunications, broadcasting, Internet service provision, computer and software industries, and media and publishing industries, where the significance of standardization and interoperability can be fundamental. In any case, digital technology can offer the potential for realizing the future electronic information highways or integrated broadband communications. However, for the multiplatform environment to proliferate in liberalized markets and for the platforms themselves to complement each other, the related prerequisites and the governing regulatory environment must favor technologically neutral conditions for competition, without giving preference to one platform over others (Chochliouros & Spiliopoulou, 2005a). Among the latest European priorities for further development of the information society sector as described above were several efforts for extending the role of digital television based on a multiplatform approach (European Commission, 2002a). If widely implemented, digital (interactive) television may complement existing PC- and Internet-based access, thus offering a potential alternative for market evolution (Chochliouros, Spiliopoulou, Chochliouros, & Kaloxylos, 2006). In particular, following current market trends, digital television and third generation (3G) mobile systems driven by commonly adopted standards can open up significant possibilities for a variety of platform access to services, offering great features of substitution and complementarity. The same option holds for the supporting networks as well (European Commission, 2003a). Within the above fast developing and fully evolutionary context, the thematic objective of digital video broadcasting (DVB) applications (including both the underlying network infrastructures and corresponding services offered) can influence a great variety of areas (http://www.dvb.org). In particular, DVB stands as a suite of internationally accepted open standards, mainly related to digital television- and data-oriented applications. These standards (in most cases already tested and adopted in the global marketplace) are maintained by the so-called DVB Project, an industry-driven consortium with more than 300 distinct members, and they are officially published by a joint technical committee (JTC) of the European Telecommunications Standards Institute (ETSI), the European Committee for Electrotechnical Standardization (CENELEC), and the European Broadcasting Union (EBU). The existing DVB standards cover all aspects of digital television, that is, from transmission through interfacing, conditional access, and interactivity for digital video, audio, and data. In particular, DVB not only includes the transmission and distribution of television program material in digital format over various media, but also a choice of associated features (considered for exploiting capabilities of all underlying technologies). However, market benefits can be best achieved if a “harmonized” approach, based on a longterm perspective, is adopted since the beginning of all corresponding efforts, intending to facilitate a progressive development towards new (and more advanced) services in a smooth and compatible manner (Oxera, 2003). An essential precondition for this progress is the adoption, in the market sector, of common standards which, while providing necessary clarity for both producers and consumers in the short term for early introduction of digital television facilities, also supply the potential for subsequent smooth upgrading to new and higher grades of service. Thus, in the framework of competitive and liberalized environments DVB can support major efforts for the penetration (and the effective adoption) of enhanced multimedia-based services (Fenger & Elwood-Smith, 2000) independently of the type and/or format of the content offered while simultaneously promoting broadband opportunities. Furthermore, being fully conformant to the requirements imposed by convergence’s aspect, DVB can advance optimized solutions for different technical communications platforms. The European market has been widely developed in the area of (interactive) digital television (Chochliouros et al., 2006; European Commission, 2003b) and the EU is now leading further deployment through DVB procedures. The focus provided by a common set of technical standards and specifications has given a market advantage and spurred the appearance of innovation perspectives.
