Primary pulmonary blastoma of monophasic variety- diagnosis and management
No full textPulmonary blastoma is a rare primary lung neoplasm, in that monophasic variety is far too rare. There are no specific clinical features seen for pulmonary blastoma; computed tomography and histopathology are diagnostic. Surgical excision is the treatment of choice; however, adjuvant chemotherapy and radiotherapy may be required in large and aggressive tumors
Mobilities in Religious Knowledge: Phiroz Mehta and the Logics of Transreligiosity in 1970s–80s South London
No full textThis paper examines transreligiosity in the context of the transmission of South Asian concepts of spirituality to the UK in the 20th century. Between the 1920s and 1990s, Indian teacher and author Phiroz Mehta (1902–1994) crossed borders in a colonial and postcolonial shuttling between India and the UK but also transgressed conceptual and practice borders of religion, teaching Indian religious concepts to post-Christian spiritual seekers in 1970s–80s South London. Mehta cultivated an elasticity between many religious and philosophical traditions, recognising the post-institutional fatigue of subjects who sought alternative forms of ‘belonging without believing’. Privileging the domestic space for teaching, as well as transitory ‘camp’ gatherings in the UK and Germany, Mehta often operated in the social margins, combining teachings from Hinduism, Buddhism, and Christianity with Zoroastrianism, Judaism (specifically Kabbalah), and Daoism. He offered his tutees the freedom to practice religion in whatever way they chose by drawing on a broad range of traditions concurrently to create a transreligiosity. This paper examines Panagiotopoulos and Roussou’s ‘transgressional webs of practising individualised forms of alternative spirituality’ in relation to Mehta’s followers in the 1970s-1980s and asks how transreligiosity relates to other theoretical analyses, such as religious exoticism, bricolage, religious appropriation, cultural re-articulation or assemblage. This paper focuses on qualitative interviews with original members of the Mehta community conducted between 2021 and 2022.</p
Design and development of a mechatronic training simulator for adult ECMO
No full textWidespread adoption of Extracorporeal Membrane Oxygenation (ECMO) in adults has been limited by unfamiliarity with the procedure, including cannulation and safe handling of the ECMO equipment. We present the design and development of a mechatronic training simulator for ECMO that can help medical professionals acquire the needed skills, gain familiarity, and reduce errors by practicing before performing the procedure on real patients. The trainer is designed as an ultrasound-compatible, wholesome simulator with realistic components such as synthetic blood vessels, cannulation pads, and a color-changing blood simulant to simulate oxygenation and deoxygenation. The simulator is integrated with a mathematical model of human physiology to simulate real-time patient vitals and training scenarios, and to control the trainer hardware. We present results related to successful cannulation under ultrasound scanning and a simple patient scenario of hypovolemia.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-05-01The student, Iti Mehta, accepted the attached license on 2019-04-24 at 10:58.The student, Iti Mehta, submitted this Thesis for approval on 2019-04-24 at 11:11.This Thesis was approved for publication on 2019-04-24 at 12:45.DSpace SAF Submission Ingestion Package generated from Vireo submission #13873 on 2019-08-22 at 15:08:02Made available in DSpace on 2019-08-23T20:36:09Z (GMT).

Previous issue date: 2016-04-27Recent advances in the semiconductor industry and process technology scaling have increased the demand for fast, robust computing. The thirst for high-processing, low power ICs is ever increasing. This has pushed the demand for high data rates in wireless and wireline communication systems in the multi-Gbps range. With higher data rates, the I/O links need to scale proportionally. However, the I/O channel bandwidth has not scaled appropriately making it the biggest bottleneck in high-speed links. Parallel links have not been able to match this increasing system performance due to issues such as crosstalk, timing skew and packaging costs. Thus there is a need for high-speed serial links. For high-speed transmission of data, there arises a need for high-speed on chip clocking circuits making the use of Phase-Locked Loops (PLLs) imperative.
This thesis includes an overview of high-speed links along with the need for PLLs. An in-depth understanding of PLL theory, loop dynamics and behavioral and transistor level simulation follows. Performance metrics such as phase noise, random jitter and deterministic jitter are discussed. Finally, this thesis concludes with an insight into All Digital Phase-Locked Loops (ADPLLs).Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01Embargo set by: Seth Robbins for item 93174

Developing competency in post-graduate students of anaesthesiology for taking informed consent for elective caesarean section
No full textBackground and Aims: Post-graduate medical students (residents) generally lack effective communication skills required to obtain informed consent. The aim of this study was to assess role play and group discussion as teaching/learning tools for improving residents' knowledge on informed consent and competency in communicating while taking informed consent. Methods: This prospective, observational study was conducted on 30 anaesthesia residents. They were first observed while obtaining informed consent and their basic knowledge regarding communication skills was checked with a pre-test questionnaire. Then, lecture and group discussion were carried out to increase the knowledge base, and their knowledge gain was checked by the same questionnaire as a post-test. Communication skills were demonstrated by role play and residents were assessed by direct unobtrusive observation using a checklist. Feedback regarding effectiveness of programme was taken from students. Statistical analyses were done using Microsoft Office Excel and SPSS software. Results: Percentage gain was 122.37% for knowledge domain. For communication skills, mean ± standard deviation for checklist was 8.93 ± 1.43 before role play and it improved to 17.96 ± 1.29 after role play. Regarding effectiveness of role play as a teaching/learning tool, 76.66% of residents said they strongly agreed and 23.33% of residents said they agreed. Likert scale for evaluation of programme was graded 4 or 5 by all residents. Conclusion: The knowledge and communication skills required for obtaining informed consent was improved significantly after role playing
Longitudinal Analysis of Renal Function using ZIP GEE on OLT Transplant Patients Undergoing NAC Prophylaxis
No full textOrgan dysfunction is associated with oxidative stress following Orthotropic Liver Transplant (OLT) surgery. N-Acetyl Cysteine (NAC) is an acetylated form of the amino acid cysteine. NAC is known to replenish glutathione in the bloodstream which helps relieve cell damage caused by oxidative stress. NAC was used in a placebo controlled study to discover its effects on organ dysfunction caused by oxidative stress following OLT surgery. A standard NAC treatment, as used to treat acetaminophen toxicity, was used as a treatment during surgery. Measures of hepatic and renal dysfunction were recorded at unequally spaced time-points for a follow-up time of one year. The Generalized Estimating Equation (GEE) approach was used to model continuous hepatic responses. Discrete renal dysfunction responses are shown to follow a unique distribution. This unique distribution was accommodated by the GEE procedure proposed by Liang and Zeger to produce consistent and efficient estimates of the treatment effect of NAC. The estimates produced contradictory results for a hypothesized protective effect of NAC against hepatic dysfunction. The public health relevance of this work is that NAC treatment, if shown to be efficacious with respect to renal function, can benefit over six thousand OLT patients each year
Visual outcomes of bilateral congenital and developmental cataracts in young children in south India and causes of poor outcome.
No full textCONTEXT: Bilateral pediatric cataracts are important cause of visual impairment in children. AIM: To study the outcome of bilateral pediatric cataract surgery in young children. SETTING AND DESIGN: Retrospective case series in a tertiary center. MATERIALS AND METHODS: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. STATISTICAL METHODS: Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. RESULTS: 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity 6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17). CONCLUSION: Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age
