ABSTRACT

Many countries are implementing distance learning in response to the Covid19 pandemic. Distance learning helped learners continue their studies as schools and universities were closed due to the pandemic. The purpose of this study is to analyze the impact of Covid-19 lockdown on learners' academic performance. This research focuses on the challenges faced by distance learning learners. The purpose of this study is to identify barriers to distance learning. This study applies the DEMATEL (Decision Making Test and Evaluation Institute) approach to assess the barriers faced by learners in distance learning. The DEMATEL strategy is being used to identify the key factors by identifying the interrelationships between the various factors. A quantitative survey method using a structured questionnaire was carried out. The questionnaire was administered to a cohort of 54 undergraduate engineering students of third semester (2nd year) pursuing Bachelor of Technology (Information Technology) in India. This study found that motivation, social interaction, and resource costs were assessed in causal groups with RiCi scores of 0.332, 0.1774, and 0.113, respectively. Technical concerns and administrative issues are categorized in the effect group with Ri-Ci values of-0.333 and-0.287 respectively and are the most important criteria based on first and second highest Ri+Ci values of 0.646524 and 0.59817, respectively. Our findings reveal that motivation is the most important barrier in remote teaching learning. A sense of self-motivation can be induced by organizing workshops, practical sessions and grooming sessions. The study would benefit academic institutions and learners as it would help them to enrich the remote teaching learning process. © 2022 by the authors.

ABSTRACT

Aim: Post operative hypocalcaemia is the most frequent complication following thyroidectomy. It can be permanent or transient hypoparathyroidism of which the incidence of permanent hypoparathyroidism is less than 3 %. This study aimed to evaluate and identify the predictors of postoperative hypocalcaemia in patients undergoing thyroidectomy. Methodology: A prospective cohort study was conducted on 52 patients at an apex care institute. Preoperative testing for serum calcium, Parathormone (PTH) and Vitamin D were done on the day of surgery. These patients were subjected to surgery as per standard protocol. Postoperative testing for PTH was done 24 hours after surgery and serum calcium on day 0 and 1. All patients were assessed clinically for signs and symptoms of hypocalcemia till 48 hours post operatively and they were correlated with biochemical parameters and season in which surgery was performed. Result(s): A total of 52 patients were operated in our institute over a period of 18 months in the midst of COVID 19 outbreaks. Both hemi thyroidectomy (40) and total thyroidectomy (12) patients were included in the study. One significant finding was the low levels of preoperative Vitamin D values among 90% of the subjects. Out of the 52 patients, 12 underwent total thyroidectomy and 40 underwent hemi thyroidectomy as per standard protocols. 54% of the patients of total thyroidectomy and 52% of the patients of hemi thyroidectomy developed clinical as well as biochemical hypocalcemia over a period of 48 hours and were managed as per standard protocol. 38% of the patients were having low calcium values preoperatively and a statistically significant correlation was found between preoperative low calcium value and development of postoperative clinical hypocalcemia (P value 0.001). There was no statistically significant correlation between Pre operative Vitamin D level and season of surgery with postoperative clinical hypocalcemia. Conclusion(s): All patients being planned for surgery, whether it is total or hemi thyroidectomy should undergo preoperative serum calcium evaluation and necessary correction if required, since preoperative low calcium is a clear predictor of post thyroidectomy clinical hypocalcemia. Further studies are required to correlate relation between Vit. D level and postoperative hypocalcemia.

ABSTRACT

SARS-CoV-2 is highly infectious and has ability to mutate into newer, more contagious, and lethal strains. Moreover, presence of comorbidities and low immunity increases the COVID-19 susceptibility and severity. Thus, COVID-19 is challenging to treat and eradicate globally. This increase stress and anxiety among the patients, worsening their condition. Even health care workers (HCWs) are distressed and anxious while managing the COVID-19. Mental stress and depression increases risk of COVID-19. Yogic breathing techniques may be beneficial in improving immunity and reducing stress and anxiety. The present study investigated the effectiveness of short and controlled Yoga-based breathing protocols in COVID-positive, COVID-recovered and HCWs. Study subjects were recruited from Postgraduate Institute of Medical Education and Research, Chandigarh, India from 13th October, 2020 to 7th January 2021. Each group was randomly divided into intervention or yoga group and non-intervention or control group. COVID-positive practiced a 5-min routine and COVID-recovered and HCW practiced 5-min and 18-min routines for 15 days. Pre-post estimation of neuropsychological parameters and heart rate variability and baseline, 7th and 15th day estimation of biochemical parameters, 6-minute walk and 1-minute sit-stand tests were conducted. Based on Ayurveda, Prakriti-type was assessed. WBC count was elevated in COVID-positive intervention (p<0.001) and control groups (p=0.003). WBC count (p=0.002) and D-dimer (p=0.002) was decreased in COVID-recovered intervention. A non-significant reduction in perceived stress and tension was noted in COVID-positive intervention. Tension was reduced and quality of life improved in HCW intervention (p>0.05). The Kapha Prakriti (48.9 %) was dominant among COVID-19 infected (positive and recovered) subjects. Distance covered in 6-min increased after intervention in COVID-positive (p=0.01) and HCW (p=0.002). The covered distance was more after intervention in all groups than control sub-group. COVID-positive intervention group shows reduced heart rate (p>0.05) and high-frequency power (p=0.01). The interventions were capable of improving exercise capacity in patients and HCW and reduced cardiovascular risk in COVID-19. The studied breathing protocol can be integrated for the management of COVID-19 and is beneficial to HCWs.

ABSTRACT

The COVID-19 pandemic has caused economic, physiological, and psychological harm to the world. A crucial step, hence, in the fight against covid is the highly efficient screening of patient cases. Conventional RT-PCR testing, even though more reliable, cannot be done on every patient as the virus has spread way faster than the world’s resources could afford. One very important screening approach that is being used across the globe is chest X-ray imaging. Since X-ray facilities are readily obtainable in healthcare systems of most countries across the globe, and with more and more X-ray systems being digitized, the cost and time of transportation are cut as well. Hence, if the detection of the virus in a CXR image can be automated using AI techniques, it will save a lot of time and effort of radiologists to have to go through hundreds of such images, and in some cases will also spare the need of doing RT-PCR testing, and since saving resources in this time is vital, automated detection can be very effective. In this work, we will explore, analytically discuss, and do a comparative study of many ML and deep learning techniques that have been taken for automated COVID-19 detection through chest X-rays (CXR). We carefully analyze the papers and derive a set of key factors for discriminating the methodologies, classification techniques, approaches, and the results that yielded. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

Clinical manifestations of coronavirus disease 2019 (COVID-19) range from mild self-limiting illness to multi-organ dysfunction and acute respiratory distress syndrome (ARDS). Also, leptospirosis manifests as mild or asymptomatic infection, and only a small number of patients progress to ARDS and develop systemic manifestation. COVID-19 and leptospira co-infection can have fatal outcomes because of augmented pathophysiological manifestations of both the disease. We here describe a case of leptospira and COVID-19 coinfection in a patient who had poor results due to multi-organ involvement

ABSTRACT

Artificial Intelligence, abbreviated as AI, is described as a collection of technologies that work together to allow machines to discern, interpret, take action, and acquire knowledge with human level of intelligence. The AI domain includes technologies such as natural language processing (NLP) and machine learning (ML). Each of these is on its separate route of development and, when combined with datasets, analytics, and computerization, may assist organisations in achieving their objectives, whether it's enhancing customer service or improving supply chain. The pipeline of the development of novel drugs is quite extensive and costly apart from being complicated. On average, this entire process requires around 12 years costing approximately 2.6 billion USD. In this age of computational power, AI-based techniques are used in almost all of the steps during the process of discovering and developing drugs. AI has been able to reduce the time requirement and amount of money involved in this process thus expediting the entire procedure of new pharmaceutical inventions. In this manuscript, we have discussed some of the major applications of AI in the pharmaceutical sector. Tools that are employed to forecast the toxicity of drugs and how some of them, for example - Toxtree, ADMET, ProTox etc. have been used by researchers in the drug discovery process, have also been talked about. Further we have mentioned how AI is proving to be a powerful tool in the fight against the COVID-19 pandemic, for example, in the detection of the SARS-Co V -2 virus, development of vaccines, genomics etc. In addition to this, we have discussed about the manner in which the penetration of AI-based companies into the pharmaceutical field has resulted in some notable outcomes, for instance - prediction of the 3-dimensional structure of proteins by DeepMind's AlphaFold2, determination of new drug contender for kidney fibrosis by Insilico Medicine's Chemistry42 etc. Furthermore, we have stated the propitious future that AI is expected to bring about in the pharma world with a special focus on drug development. © 2022 IEEE.

ABSTRACT

Introduction: Studies show that children account for only 1-5% of diagnosed COVID-19 cases, they have milder disease than adults and deaths are extremely rare. The complete clinical picture of pediatric COVID-19 has not yet been fully reported or defined. Additionally, the South African pediatric population has unique clinical characteristics and risk implications and needs investigating. We aimed to characterize COVID-19 in Cape Town children. Methods: The UCT COVID-19 pediatric repository is a prospective cohort recruited via convenience sampling at 3 Western Cape Hospitals. All patients ≤ 18 years who test COVID-19 positive are eligible for inclusion in the study. Results: To date 227 participants, 56%(125/227) male with median age 2 years (IQR:0-6), have been enrolled. Only 28(12%) participants were in contact with a confirmed COVID-19 positive case, 67% of these, were first degree relatives, 28% second degree relatives and 6% health care workers. Comorbidities were present in 125(56%) participants. Of 32 recorded comorbidities, congenital heart disease (CHD), found in 7% of participants, ranked third. CHD subtypes included PDA (4), Tetralogy of Fallot (3), AVSD (2), Pulmonary atresia with VSD (2), truncus arteriosus (1), Coarctation of the Aorta (1), Congenital aortic valve stenosis (1), and ASD (1). Other cardiac comorbidities were, cardiomyopathy (2), primary pulmonary hypertension (1) and rhabdomyoma (1). On presentation 173 (76%) were symptomatic. Predominant symptoms included cough 40%, history of fever 36%, documented fever 34%, difficulty breathing 28%, and nausea or vomiting 20%. On examination, 65% had abnormal heart rates, 47% abnormal respiratory rates, 35% were in respiratory distress and 24% were hypoxic. Of the 227 patients, 169(74%) were admitted to hospital and 33 (15%) were admitted to ICU. In the ICU 79% of patients required non-invasive and 24% invasive ventilation, median length of ICU admission was 3 days (IQR:2-7.5). During admission 38(17%) patients developed COVID-19 complications: secondary infection 10%, sepsis 4%, MIS-C 2%, and myocarditis or new onset heart failure 1%) and 2(0.9%) died, including one patient with AVSD, who presented with severe pulmonary hypertension and acute heart failure post cardiac surgery. Conclusion: We present the initial findings of the UCT pediatric COVID-19 registry. We anticipate that these data will help to complete the clinical picture of COVID-19 in the South African pediatric population.

ABSTRACT

Coronavirus disease 2019 (COVID-19) co-infection in patients with myasthenia gravis has not been well described. Our primary aim is to describe the course of illness of a myasthenia patient who developed repeated episodes of myasthenic crisis along with severe COVID-19 infection. This case highlights the need to monitor the immune response to the infection accurately, and treatment of myasthenia gravis with COVID-19 should be tailored to the individual patient.

ABSTRACT

TOPIC: Pulmonary Manifestations of Systemic Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Epidermolysis Bullosa Acquisita (EBA) is an autoimmune disease which presents with chronic blistering and scarring of the skin and mucous membranes. We present a case of EBA presenting with Usual Interstitial Pneumonia (UIP) and pneumomediastinum;an extremely rare complication. CASE PRESENTATION: An 84 year-old man presented to the emergency department with worsening dyspnea and multiple blistering lesions along with associated fatigue and weight loss for approximately 6 months. Past medical history was significant for previously diagnosed EBA, hypertension and hyperlipidemia. The patient is a Veteran and retired salesman who denied hazardous occupational exposure. Physical examination revealed bilaterally decreased breath sounds and also multiple crusted blisters in all four extremities. COVID test was negative and initial laboratory panel was only remarkable for mild macrocytic anemia. Outpatient chest radiograph obtained ten days prior to admission (fig 1) and repeat on admission showed bilateral interstitial reticulonodular opacities with new asymmetric opacifications in the right lung apex (fig 2). Chest CT angiogram demonstrated fibrotic changes and honeycombing in the peripheries and bases with moderate pneumomediastinum (fig 3). He was diagnosed with UIP given the radiologic pattern and this was attributed to be likely due to his current EBA flare-up given no other obvious trigger. The patient's home dose of dapsone for EBA was continued and he was given nebulized bronchodilators with improvement in his symptoms over 48 hours. Pulmonology was consulted and recommended outpatient follow up in 3 weeks as he remained hemodynamically stable and was saturating well on room air. Repeat Chest CT on follow up showed improvement of the pneumomediastinum (fig 4). Pulmonary function tests showed moderate restrictive lung disease with moderately reduced diffusing capacity, however his symptoms were mostly resolved. DISCUSSION: EBA is an orphan autoimmune whose pathophysiology involves auto-antibodies against type VII collagen (COL7). These create a specific u-serrated pattern on peri-lesional skin biopsies [1]. COL7 is also known to be a component of the pulmonary basement membrane;with collagen accounting for a third of the dry mass of the lung. EBA has been weakly associated with multiple autoimmune diseases including anecdotal reports of association with pulmonary fibrosis [2]. However extensive review of literature showed no published case reports connecting the two conditions. In our opinion, this patient's presentation is likely a result of the interaction of COL7 antibodies with the pulmonary basement membrane leading to UIP with pneumomediastinum. CONCLUSIONS: This case highlights the rare association between EBA and UIP which are likely connected pathophysiologically by anti-COL7 antibodies. Further research and analysis will be needed to confidently establish this association. REFERENCE #1: Koga H, Prost-Squarcioni C, Iwata H, Jonkman MF, Ludwig RJ, Bieber K.

ABSTRACT

Introduction: The current COVID-19 pandemic has posed unforeseen challenges, including sudden loss of or limited access to health care services. One subgroup of individuals affected are the prelingual hearing-impaired children who need regular auditory verbal therapy (AVT). We share our experience of conducting unplanned remote telepractice for such children in a resource-constrained setting-the challenges faced and the barriers overcome. Method: The study was conducted at a tertiary care center in northwestern India. A total of 21 prelingual hearing-impaired pediatric cochlear implantees were enrolled after taking informed teleconsent from the parents/caregiver, commencing from the period of nationwide lockdown. Telepractice sessions were conducted by the parent under the supervision of the speech-language pathologist (Scalp) via video calls (or audio calls) employing home-based activities. At the end of 6 weeks, the Scalp administered a questionnaire via phone calls to ascertain the feedback and overall experience of the parents with telepractice, and their responses were compiled. Also, after 6 months of telepractice, the performance of the children was assessed using PS score, Infant-Toddler Meaningful Auditory Integration Scale score, and Speech Intelligibility Rating score. These were compared with baseline pre-teletherapy scores. Results: The mean age of children was 5.8 years (2-13 years);10 were male and 11 female. A majority of parents had a positive experience in terms of a better understanding of their child's learning challenges (90%), overall satisfaction level as ≥3 (90%), and willingness to recommend telepractice to others and feasibility (57%). Post-teletherapy performance scores showed satisfactory improvement. Conclusion: Implementing unplanned telepractice posed a variety of challenges. The sudden switch over from officebased therapy to telepractice posed difficulties for not only the child and parent but for the Scalp as well. The challenges we faced necessitated out-of-the-box thinking on a situation-tosituation basis, yielding encouraging opportunities and overall encouraging results.
