  • Purpose: The debate is still on-going as to whether a transthoracic esophagectomy (TTE) or a transhiatal esophagectomy(THE) is the proper treatment for patients with cardia and esophageal cancers. This study tries to demonstrate and assess the efficacy and the validity of both surgeries. Materials and Methods: In a retrospective study, data from 52 cases of patients with esophageal and/or cardia cancer who received a surgical operation during the last decade were analyzed. Results: A TTE was done in 20 cases and a THE in 32 cases. The average times for the operations were 558.0 min for a TTE and 451.7 min for a THE (P>0.05). The estimated blood loss was 1,825.0 ml in a TTE and 1459.4 ml in a THE (P>0.05). The amounts of transfusion during the operations were 3.9 units in a TTE and 2.6 units in a THE (P<0.05). Post-operative complications occurred in 15 cases of TTE and 23 cases of THE. The average length of stay in the hospital was 25.6 days for a TTE and 20.6 days for a THE. The 5-year survival rate was $10\%$ for TTE patients and $28\%$ for THE patients (P>0.05). Conclusion: For most factors, including morbidity and mortality, there was no statistically significant difference between a TTE and a THE. However, a THE is expected to be more convenient, leading to a shorter operative duration, a shorter post-operative hospitalization and lesser amounts of hemorrhage and transfusion. Hence, the THE may be a more valid or efficient surgical method for those patients with cardia and esophagus cancer who require a resection of the esophagus.

  • BACKGROUND: The prognostic utility of follow-up transthoracic echocardiography (FU-TTE) in patients with hypertrophic cardiomyopathy (HCM) is unclear, specifically in terms of whether changes in echocardiographic parameters in routine FU-TTE parameters are associated with cardiovascular outcomes. METHODS: From 2010 to 2017, 162 patients with HCM were retrospectively enrolled in this study. Using echocardiography, HCM was diagnosed based on morphological criteria. Patients with other diseases that cause cardiac hypertrophy were excluded. TTE parameters at baseline and FU were analyzed. FU-TTE was designated as the last recorded value in patients who did not develop any cardiovascular event or the latest exam before event development. Clinical outcomes were acute heart failure, cardiac death, arrhythmia, ischemic stroke, and cardiogenic syncope. RESULTS: Median interval between the baseline TTE and FU-TTE was 3.3 years. Median clinical FU duration was 4.7 years. Septal trans-mitral velocity/mitral annular tissue Doppler velocity (E/e'), tricuspid regurgitation velocity, left ventricular ejection fraction (LVEF), and left atrial volume index (LAVI) at baseline were recorded. LVEF, LAVI, and E/e' values were associated with poor outcomes. However, no delta values predicted HCM-related cardiovascular outcomes. Logistic regression models incorporating changes in TTE parameters had no significant findings. Baseline LAVI was the best predictor of a poor prognosis. In survival analysis, an already enlarged or increased size LAVI was associated with poorer clinical outcomes. CONCLUSIONS: Changes in echocardiographic parameters extracted from TTE did not assist in predicting clinical outcomes. Cross-sectionally evaluated TTE parameters were superior to changes in TTE parameters between baseline and FU at predicting cardiovascular events.

  • The tissue extract (TTE) of a marine snail Telescopium telescopium, collected from the coastal regions of West Bengal, India, was extensively screened for pharmacological and biochemical properties. Telescopium telescopium (TTE) produced significant lysis of washed rat erythrocytes (both direct and indirect), produced haemorrhagic lesions in the skin and also released haemoglobin (in vitro tissue damage) from different tissue samples. TTE was found to produce pro-inflammatory effects when injected into the rat hind paw and also increased peritoneal vascular permeability. Furthermore, intravenous administration of TTE produced a decrease in blood pressure (hypotensive effect) in anaesthetized rats. The extract produced potent esterase activity, as was evident from the breakdown of FDA with subsequent release of fluorescein (in vitro). TTE also demonstrated prominent cholinesterase, phospholipase, phosphatase and protease activities.

  • Purpose : Accurate measurement of defect size is important in transcatheter closure of atrial septal defect (ASD). We performed this study to analyze the difference between the measured ASD size and balloon occlusive diameter (BOD) by transthoracic (TTE) or transesophageal echocardiography (TEE). Methods : We investigated 78 patients who underwent transcatheter closure of ASD. The defect size and the distance between the surrounding structures were measured by TTE and TEE. The BOD was measured by TEE during cardiac catheterization. Clinical characteristics and echocardiographic data were compared and analyzed. Results : The difference between BOD and diameter by TTE was $4.8{\pm}3.6mm$ on short axis view, $5.4{\pm}3.2mm$ on long axis view. The difference between BOD and diameter by TEE was $3.6{\pm}2.2mm$ on short axis view, $4.2{\pm}3.1mm$ on long axis view. The difference between BOD and the diameter of defects on TTE, TEE had statistically significant positive correlations with the age of the patients, distance between the, defect and posterior atrial septal wall, the distance between the defect and the mitral valve leaflet, and the diameter of defects and the length of the atrial septum on TTE (P<0.05). Conclusion : BOD of ASD can be estimated by the diameter on TTE and TEE. BOD is expected to measure larger, depending on the size of defects, the distance from surrounding structures and the location of defects on echocardiography. Our data offers important information on details of transcatheter ASD closure which can be helpful in predicting suitability and judging the procedural appropriateness during the procedure.

  • A pulsed ferrite magnetic field generator (FMFG) was designed for the use in the 1000 m long through-the-earth (TTE) communication system for mining disaster situations. To miniaturize the TTE system, a ferrite core having 10,000 of permeability was used for the FMFG. Attenuation of the magnetic field intensity from the FMFG (200-turn and 0.18 m diameter) was calculated to be 89.95 dB at 1000 m depth soil having 0.1 S/m of conductivity. This attenuation was lower than 151.13 dB attenuation of 1 kHz electromagnetic wave at the same conditions. Therefore, the magnetic-field was found to be desirable as a signal carrier source for TTE communications as compared to the electromagnetic wave. The designed FMFG generates the magnetic field intensity of $1{\times}10^{-10}$ Tesla at 1000 m depth. This magnetic field is detectable by compact magnetic sensors such as flux gate or magnetic tunneling junction sensor. Therefore, the miniature FMFG TTE communication system can replace the conventional electromagnetic wave carrier type TTE system and allow reliable signal transmission between rescuer and trapped miners.

  • Purpose This study aimed to compare the diagnostic performance of cardiac CT and transthoracic echocardiogram (TTE) depending on the degree of valvular calcification and bicuspid aortic valve (BAV) subtype. Materials and Methods This retrospective study included 266 consecutive patients (106 with BAV and 160 with tricuspid aortic valve) who underwent cardiac CT and TTE before aortic valve replacement. Cardiac CT was used to evaluate the morphology of the aortic valve, and a calcium scoring scan was used to quantify valve calcium. The aortic valves were classified into fused and two-sinus types. The diagnostic accuracy of cardiac CT and TTE was calculated using a reference standard for intraoperative inspection. Results CT demonstrated significantly higher sensitivity, negative predictive value, and accuracy than TTE in detecting BAV (p < 0.001, p < 0.001, and p = 0.003, respectively). The TTE sensitivity tended to decrease as valvular calcification increased. The error rate of TTE for CT was 10.9% for the twosinus type of BAV and 28.3% for the fused type (p = 0.044). Conclusion Cardiac CT had a higher diagnostic performance in detecting BAV than TTE and may help diagnose BAV, particularly in patients with severe valvular calcification.

  • The microalga, Tetrathelmis tetrathele, is used in the development of products for the aquaculture, food, and nutraceutical industries. In the present study, we investigated whether the T. tetrathele ethanolic extract (TTE), which has anti-inflammatory properties, can confer protection against alopecia and improve scalp health, influence the proliferation of human keratinocytes, HaCaT cells, and human hair follicle dermal papilla cells (HFDPC), or inhibit 5α-reductase activity. We found that TTE inhibited the production of the inflammatory mediator, nitric oxide (NO), and prostaglandin E2 (PGE2) without cytotoxicity in LPS-stimulated RAW 264.7 cells. In addition, TTE encouraged the proliferation of HaCaT cells and HFDPC. Our results showed that TTE had anti-inflammatory activities, proliferated HaCaT cells and HFDPC, and inhibited 5α-reductase activity. Therefore, we suggest that T. tetrathele could be a potent therapeutic agent for alopecia prevention and scalp improvement.

  • In addition to the well-known 'Frankfurt Kitchen', Austrian female architect Margarette $Sch{\ddot{u}}tte-Lihotzky^{\prime}s$ architectural achievements include a study on the housing for working class, contribution to the resident participation movement, the planning of multi-family housing complexes, rational floor plan design, and the design and study of interior spaces. The purpose of this study is to investigate how she, who played intermediate roles between an architect and a social reformer, reflected social issues and the demands of living on the housing plans in the Red Wien era and to discuss diverse issues of modern residential planning furthermore. In this study, first, the housing situation in Vienna immediately after World War I was grasped and the architectural and housing discourses at that time were examined. Thereafter, cases of $Sch{\ddot{u}}tte-Lihotzky^{\prime}s$ works were investigated and analyzed. In the period of transition to modern times, the concepts of residential planning of $Sch{\ddot{u}}tte-Lihotzky$, who began as a social democratic architect, often showed transitional tendencies in private and public functions of housing, spatial distribution for the daily life, and functions of modern family and home. However, thereafter, the paradigm of the rationalism-functionalism was already sprouting from her architectural and residential plans. In conclusion, it can be said that the works of $Sch{\ddot{u}}tte-Lihotzky$ has realized the social responsibility of residential planning and become a cornerstone of the later modern housing.

  • In the turn of the twentieth century, Vienna emerged as a great cultural centre that stood at the forefront of developments in music, psychology, and the natural sciences. Equally influential, and still tremendously popular today, are the designs of the Wiener $Werkst{\ddot{a}}tte$ a group that was at the heart of the city's cultural scene and whose collaborators included such luminaries as the architect Josef Hoffman and the designer Koloman Moser under the slogan of Gesamtkunstwerk. The term "Gesamtkunstwerk" was introduced in the romantic period. It describes the desire for and practice of combining various art forms into a whole, such as performances that combine text, visual arts, various design and architecture. Richard Wagner was one of the early theorists of the concept, inspiring many modernist artists. As a co-founder of the Wiener $Werkst{\ddot{a}}tte$, Josef Hoffmann had a decisive influence on modern Viennese architecture and Interior design on the basis of the concept of Gesamtkunstwerk. In this view point, this study is to analyze about the generative background and design characteristics of gesamtkunstwerk advocated Wiener $Werkst{\ddot{a}}tte$. Josef Hoffmann was by all accounts a very successful architect and Interior designer in Vienna. His influence would undoubtedly have been felt simply because of his talent and energy. His special ability to range across multiple domains, coupled with a willingness to collaborate with other artists has created a synthesis and synergy that is compelling to this day.

  • The study aimed to compare the 2 main types of insurance used by colorectal cancer (CRC) patients in a university hospital in Thailand: universal coverage (UC) and 'Civil Servant Medical Benefit Scheme' (CSMBS) in terms of hospital expenditure and survival outcomes. CRC cases in stages I-IV who were operated on and had completed their adjuvant therapy in Songklanagarind Hospital from 2004 through 2013 were retrospectively reviewed regarding their hospital expenditure, focusing on surgical and chemotherapy costs. Of 1,013 cases analyzed, 524 (51.7%) were in the UC group while 489 (48.3%) belonged to the CSMBS group. Cases with stage IV disease were significantly more frequent in the UC group. Average total treatment expenditure (TTE) was 143,780 Thai Baht (THB) (1 US$ =~ 30 THB). The TTE increased with tumor stage and the chemotherapy cost contributed the most to the TTE increment. TTE in the CSMBS group was significantly higher than in the UC group for stage II-III CRCs. The majority of cases in the UC group (65.5%) used deGramont or Mayo as their first line regimen, and the proportion of cases who started with a capecitabine-based regimen (XELOX or $Xeloda^{(R)}$) was significantly higher in the CSMBS group (61.0% compared to 24.5% in the UC group, p-value < 0.01). On survival analysis, overall survival (OS) and progress free survival in the CSMBS group were significantly better than in the UC group. The 5-year OS in the CSMBS and UC groups were 84.3% and 74.6%, respectively (p-value < 0.01). In conclusion, the study indicates that in Thailand, the type of insurance influences resource utilization, especially the choice of chemotherapy, in CRC cases. This disparity in treatment, in turn, results in a gap in treatment outcomes.
