A study on the functional and radiological outcome with complications in the management of proximal humerus fractures operated with proximal humerus internal locking osteosynthesis system
No full textBackground: A number of opinions exist regarding the management of proximal humerus fractures starting from conservative to tension band-wiring to internal fixation with plates. The aim of this study is to assess the functional outcome, the radiological outcome and the complications associated with the management of proximal humerus fractures treated with proximal humerus interlocking osteosynthesis system (PHILOS).
Methods: A prospective descriptive study was undertaken comprising of 40 patients. Closed proximal humerus fractures meeting Neer’s criteria for operative displacement were enrolled. Patients underwent open reduction internal fixation with PHILOS plate. Post-operative radiological outcome was estimated with follow-up x-rays, functional outcome using the Constant and Murley score.
Results: 60% patients were female, with the most common mode of injury being fall at a ground level. Late complications were noted in 25% of patients, which were malunion 5%, joint stiffness 10%, joint instability 5% and heterotopic ossification 5%. The mean Constant and Murley score was 79.5 and it was found to be statistically significant to the type of fracture according to the Neer’s classification (Kruskal Wallis test, p=0.005). Joint stiffness was also found to be statistically significantly correlated to the type of fracture pattern (Chi square test, p=0.016). The average time to union was 10 weeks.
Conclusions: Thus, by this study it can be expressed due to appropriate articular reduction by open reduction and by the use of a fixed angle implant like the PHILOS plate, operative management of proximal humerus fractures by the said implant is a viable option to enable quick and early rehabilitation of patients
Prospective evaluation of the role of limb reconstruction system in fracture non-union of femur: a case series
No full textTraditionally the Ilizarov’s ring fixator was used in the management of non-union of long bones, especially in the cases with infection. But limb reconstruction system (LRS) is a viable lightweight, technically easier alternative for the same. The aim of this study was to assess the functional outcome, the radiological outcome and the complications associated with the management of fracture non-union femur treated with LRS. A prospective case series was undertaken comprising of 10 patients. Both infected and non-infected shaft of femur fractures were enrolled. Patients underwent debridement, implant removal and definitive fixation with LRS. Post-operative radiological outcome and functional outcome using the ASAMI (Association for the Study and Application of the Method of Ilizarov group) score. In 70% cases the mechanism of injury was road traffic accident. Mean period of non-union before admission was 11.9 months, mean time for union was 10.10 months, with 90.0% cases successfully uniting. 70% cases underwent lengthening following Ilizarov’s principles. ASAMI radiological outcome was excellent in 70%, good in 10%, fair in 10% and poor in 10% cases. ASAMI functional outcome was excellent in 60%, good in 10%, fair in 10% and poor in 20% cases. Pin tract infection was the most common problem at 70.0% while knee stiffness at 40% was the most common true complication. Thus by this study it can be expressed that LRS is a feasible alternative to ring fixators for the management of fracture non-union shaft of femur

Inquest of Current Situation in Afghanistan Under Taliban Rule Using Sentiment Analysis and Volume Analysis
No full textMicroblogging websites and social media platforms serve as a potential source for mining public opinions and sentiments on a variety of subjects including the prevailing situations in war-afflicted countries. In particular, Twitter has a large number of geotagged tweets that make the analysis of sentiments across time and space possible. This study performs volume analysis and sentiment analysis using LDA (Latent Dirichlet Allocation) and text mining over two datasets collected for different periods. To increase the adequacy and efficacy of the sentiment analysis, a hybrid feature engineering approach is proposed that elevates the performance of machine learning models. Geotagged tweets are used for volume analysis indicating that the highest number of tweets is originated from India, the US, the UK, Pakistan, and Afghanistan. Analysis of positive and negative tweets reveals that negative tweets are mostly originated from India and the US. On the contrary, positive tweets belong to Pakistan and Afghanistan. LDA is used for topic modeling on two datasets containing tweets about the current situation after the Taliban take control of Afghanistan. Topics extracted through LDA suggest that majority of the Afghanistan people seem satisfied with the Taliban�s takeover while the topics from negative tweets reveal that issues discussed in negative tweets are related to the US concerns in Afghanistan. Sentiment analysis over two different datasets indicates that the trend of the sentiments has been shifted positively over three weeks
Strategic factors for implementing a multiple career path construction doctoral program: a mixed methods study
No full text2022 Summer.Includes bibliographical references.According to the recent literature, a notable percentage of STEM doctoral graduates prefer employment in non-academic career paths such as industry due to diminishing opportunities in academia. However, the doctoral education in the U.S. is designed to prepare graduates to become researchers and teachers for careers in academia. There is limited training available to Ph.D. students related to their training for non-academic career paths. Construction Ph.D. programs are designated as STEM programs and are no exception to this changing career preferences of Ph.D. graduates. Given the changing career landscape of doctoral graduates, it is important for construction Ph.D. programs to prepare doctoral students for success in diverse career paths (academia and industry). A large share of the current research in doctoral education primarily focusses on engineering disciplines, and very limited knowledge is available related to preparation of construction focused Ph.D. graduates effectively for multiple career paths. The broad research objective of this study is to develop strategic factors for construction Ph.D. programs to prepare students for diverse career paths. To achieve the research objective, the study explored the factors that influence construction Ph.D. students career choices through social cognitive career theory theoretical lens, competencies required by construction Ph.D. students for careers in academia and industry, various ways construction Ph.D. programs can prepare students for diverse career paths, and benefits of preparing construction Ph.D. students for various career paths. The study adopted a mixed methods approach, where 38 qualitative interviews were conducted and a quantitative survey was developed and administered (329 responses) with construction Ph.D. students, construction Ph.D. graduates working in the industry, construction faculty, and construction industry professionals. Results indicate that construction-focused Ph.D. students are equally interested in industry-related career choices alongside academia. Factors such as interest in teaching and research, passion for student mentoring and engagement, flexibility in working hours, support from an advisor, unawareness about non-academic opportunities, and satisfaction obtained from teaching influence construction Ph.D. students towards academic careers. Factors such as better salaries, ability to make a difference and advance construction industry, disinterest in academic culture, lack of enough academic jobs, no support from an advisor, and competitive academic funding climate influence construction Ph.D. students towards non-academic (industry) careers. Written and oral communication, problem solving skills, and critical independent thinking competencies are critical to employability success of construction Ph.D. students in both academic and industry career paths. Opportunities to complete industry internships, performing research relevant to construction industry's challenges by balancing both theory and practice, support from advisor related to either of the career choices, networking with both academic and industry professionals are important strategies to prepare construction Ph.D. student for diverse career paths. Preparing construction Ph.D. students for diverse career paths not only improves employability of Ph.D. students but also enhances university-industry research collaborations and improves the ability of construction industry to constantly innovate, adopt technology, and gain access to university research relevant to their needs
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
No full textBackground: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures. Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge. Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to sideeffects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (β coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and lowand middle-income countries, patient-reported outcomes did not. Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
