5% (132/160) with an accuracy of 75% (120/160) for N staging. The diagnostic accuracy of CT for early gastric carcinoma in our study was 93.75% with high specificity of 96% but low sensitivity of 66.7%. Conclusion MDCT using gaseous and hydro-distension of stomach is an excellent modality for near accurate preoperative T staging of gastric cancer. However, CT has a limited role in the N staging of gastric cancer. This study also suggested that the combined use of virtual gastroscopy and MPR images helps in better detection of early gastric cancers.Background A wide range of adjuvant treatment regimens exist in gastric carcinoma patients which include chemotherapy, radiotherapy, and/or both either sequential or concurrent. The study aimed to assess the benefit of adjuvant sequential chemotherapy followed by radiotherapy for operable gastric cancers and evaluate the prognostic factors associated with clinical outcomes. Methods Patients of stage IB-III gastric carcinoma who underwent radical surgery followed by adjuvant treatment from January 2013 to December 2016 were analyzed retrospectively. Survival was computed using Kaplan-Meier method and prognostic factors were analyzed in multivariate analysis using Cox progression hazard model. A P value less then 0.05 was taken as statistically significant. Results A total of 108 patients were identified with a median follow-up of 31.7 months (range 6-96). Seventy-two percent of the patients received adjuvant sequential chemoradiation (N = 77) and 28% of patients received chemotherapy alone. The median survival was 26 months (95% CI 23.09-28.90). Overall survival (OS) rates for 1, 2, 3, 4, and 5 years were 88.9%, 57.4%, 40.7%, 28.8%, and 20.4%, respectively. Five-year OS for stage-IB, II, and III was 75%, 45%, and 8.3%, respectively (p = 0.023). Surgical margin positivity (9.5% vs. 26.9%, p = 0.042), signet-ring cell histology (6.5% vs. 25.8%, p = 0.00), and adjuvant sequential chemoradiation (p = 0.002) showed a significant impact on survival outcomes and proved as independent prognostic factors. Conclusion The present study demonstrated that survival in gastric carcinoma is influenced by the stage of disease and surgical margins. In locally advanced patients, radical surgery followed by sequential chemoradiation based on a doublet/triplet regimen was an independent prognostic factor for survival. Majority of patients in our set-up presented in locally advanced stage, curative resection followed by adjuvant sequential chemoradiation was an independent prognostic factor for survival.Molecular mechanics (MM) and molecular dynamics (MD) simulation method were applied to explore the impact of temperature (220-380 K) on the thermostability, sensitivity, and mechanical performance of RDX (1,3,5-trinitro-1,3,5-triazacyco-hexane)/HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocane) energetic cocrystal and mixture models. The mechanical property, the maximum trigger bond length ([Formula see text]), binding energy, and cohesive energy density (CED) of the pure RDX, β-HMX crystal, the cocrystal, and mixture models were acquired and compared. The results manifest that temperature has an important impact on the binding capacity between the components of the cocrystal and mixture. The binding energies decrease as the temperature rises, and the cocrystal has larger values than those of mixture. For all the models, the [Formula see text] increases and the CEDs decrease with the rising temperature, implying that the sensitivity of the explosives increases, while the [Formula see text] values of the cocrystal are smaller than those of HMX and the CED values are between those of RDX and β-HMX, indicating that the sensitivity has been enhanced through co-crystallization. As the temperature increases, the shear modulus (G), bulk modulus (K), and tensile modulus (E) values of all models have an evident downtrend. Simultaneously, G, K, and E values of the cocrystal model are less than those of RDX and β-HMX, while the K/G ratio and Cauchy pressure (C12-C44) are larger, signifying that co-crystallization can weaken the brittleness and enhance the ductility of the pure crystals. Compared with the mixture, the cocrystal has better ductility and stability.Introduction Cardiac rehabilitation after transcatheter aortic valve replacement (TAVR) safely improves exercise tolerance, functional independence, and quality of life. However, barriers such as transportation, cost, and limited access to rehabilitation programs prohibits participation. In 2010, the Veterans Affairs Medical Center (VAMC) started a 12-week home-based cardiac rehabilitation (HBCR) program at 13 sites around the country to increase participation by reducing such barriers. We present the findings of HBCR in post-TAVR patients from the VAMC in Gainesville, FL, USA. Methods Fifty-nine patients who underwent TAVR between 2015 and 2018 at the Gainesville VA were offered HBCR. Forty-one patients enrolled, 28 completed the program, and 14 completed the surveys. We used various performance measures including Life's Simple 7 survey, 6-min Walk (6-MW), Duke Activity Survey Index (DASI), and Short Form-36 (SF-36) health survey to assess the pre and post-HBCR changes in emotional, functional, and physical well-being of the patients. Results Paired comparison of pre and post-HBCR using Wilcoxon signed-rank test revealed a statistically significant difference in the pre and post-HBCR scores for DASI, DASI-Mets, and SF-36 physical functioning (p values 0.05, 0.034, and 0.016, respectively), suggesting an improvement in the patients' physical functioning after participating in the HBCR program. Conclusions In conclusion, our pilot study offers novel insight into the role of HBCR in improving physical health and well-being in post-TAVR patients while eliminating the barriers of transportation and access to cardiac rehabilitation programs.The ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has profoundly impacted all fields of medicine. Infection with SARS-CoV-2 and the resulting coronavirus of 2019 (COVID-19) syndrome has multiorgan effects. The pandemic has united researchers from bench to bedside in attempts to understand the pathophysiology of the disease and define optimal treatment strategies. Cardiovascular disease is highly prevalent and a leading cause of death across gender, race, and ethnic groups. As the pandemic spreads, there is increasing concern about the cardiovascular effects of the viral infection and the interaction of infection with existing cardiovascular disease. Additionally, there are concerns about the cardiac effects of the numerous treatment agents under study. It will be essential for cardiologists to understand the interplay between underlying cardiac comorbidities, acute cardiovascular effects of COVID-19 disease, and adverse effects of new treatments. Here we describe emerging evidence of the epidemiology of SARS-CoV-2 infection and underlying cardiovascular disease, the evidence for direct myocardial injury in SARS-CoV-2 infection, the specific presentations of cardiovascular involvement by SARS-CoV-2, and the cardiac effects of emerging treatments.Purpose The aim of this study is to compare the long-term follow-up outcomes of traditional and accelerated corneal cross-linking (CXL) for keratoconus. Methods This retrospective comparative cohort study included patients with keratoconus who underwent corneal cross-linking (CXL) between August 2008 and December 2016. Patients treated before August 2013 underwent the traditional Dresden protocol, and those treated subsequently received the accelerated protocol, i.e., 0.1% riboflavin soaking for 10 min, followed by pulsed UV-A irradiation at 30 mW/cm2 for 8 min, and a total irradiation power of 7.2 J/cm2. The primary outcome was the success rate in halting the disease progression. The postoperative changes in visual acuity, keratometry readings, endothelial cell count and complications following accelerated CXL and conventional CXL were compared. Results This study evaluated 113 eyes over a mean follow-up period of 37.61 ± 16.34 months. It was found that 89.6% and 95.7% of the eyes were successfully treated with the traditional and accelerated protocols, respectively (p = 0.239). The corrected-distance visual acuity improved in both groups, but it was significantly better following the accelerated protocol (p = 0.037). Traditional protocol group had more postoperative complications than the accelerated group (8.9% versus 2%), although not reaching statistically significant difference (p = 0.142). There were no significant differences in the topographic (p = 0.122) and refractive (p = 0.570) outcomes. Conclusion Accelerated CXL and conventional CXL are both safe and effective, and the long-term follow-up showed that the accelerated protocol was similar to the standard one in terms of halting keratoconus and achieving visual outcomes. Because of its potential benefits, the accelerated protocol may be considered for the treatment of progressive keratoconus.Purpose To evaluate one-year visual, refractive, and topographic outcomes of 58 eyes of 53 keratoconus patients who underwent surgery with a progressive thickness intrastromal corneal ring segment (ICRS). Methods This multi-center, retrospective, observational study evaluates the one-year effects of progressive thickness ICRS implanted in keratoconus patients meeting the inclusion criteria. One or two progressive ICRS were implanted in the selected eyes after creating an intrastromal tunnel with a femtosecond laser. Pre- and postoperative uncorrected distance visual acuity, best-corrected distance visual acuity, manifest refraction (both spherical equivalent and cylindrical refractions), corneal astigmatism, maximum keratometry, corneal thickness, and corneal topography measurements and indices were evaluated. Results In this retrospective case series, 58 eyes of 53 keratoconus patients were included with a follow-up of 12 months. The mean age was 30.89 ± 11.90 years. There were improvements postoperatively in mean values of visual acuities, both uncorrected from 0.71 (preoperatively) to 0.28 (log MAR), and best-corrected from 0.28 to 0.10 (log MAR), mean cylindrical refraction from - 2.35 ± 1.51 to - 4.15 ± 2.23 D, and mean spherical equivalent from - 2.10 ± 2.25 to - 4.64 ± 3.2 D. There was also a reduction in maximal keratometry from 54.21 D preoperatively to 50.93 D postoperatively. Conclusion The implantation of the progressive thickness ICRS is an effective and safe method to improve the vision of keratoconic eyes. Corneal stability was maintained at the 12-month mark.Purpose MTA apical plug approach is considered the gold standard in managing immature teeth with necrotic pulp tissues but does not increase root dimensions. SMIFH2 manufacturer Regenerative Endodontic Therapy (RET) has been advocated as an alternative technique for management of these teeth. This study aimed to assess the knowledge, experience and the opinions of dentists treating paediatric patients in the European and Arabian regions on RET. Methods A cross-sectional, pre-piloted 23-item self-administered questionnaire survey was distributed electronically using the Bristol Online Survey tool through the mailing list of the European Academy of Paediatric Dentistry, the Arabian Academy of Paediatric Dentistry's and the Egyptian Society of Paediatric Dentistry. Results 308 respondents completed the survey. Approximately half practised RET (N = 158; 51.3%), which was most frequently used to manage non-vital traumatized teeth. Majority of RET practitioners worked in university or dental institute practices. Protocol differences with deviation from the current published RET guidelines were observed.
