ABSTRACT
The pandemic situation is affected in various ways in the education domain. The sudden transformation from offline to online teaching-learning process made students and teachers use different tools like WhatsApp for communication. The reason for this consideration is to investigate the impacts of WhatsApp utilized for instruction and decide the suppositions of understudies towards the method. The study is designed, keeping in mind the current COVID-19 situation and how it affected the education system turning it into online mode. On different questionnaires, regression and heatmap analysis is performed. The investigation showed that both learning situations have diverse impacts on the victory of understudies while supporting the conventional environment by utilizing WhatsApp is more successful for the increment of victory. The assessment moreover showed that students had superior pleasant reviews closer to the usage of WhatsApp in their courses. They requested the same workout in their one-of-a-kind courses as well. They expressed that picking up information can moreover take out unwittingly and the messages with pics were more prominent and viable for their picking up information. Be that as it may, some college understudies have communicated harming audits approximately the timing of a few posts and the repetitive posts within the bunch. At long last, it is supported that the utilization of WhatsApp within the preparing framework is to be energized as a steady innovation. . © 2023 IEEE.
ABSTRACT
COVID-19 emerged as one of the major outbreak to human society and has been declared as pandemic by World Health Organization (WHO). The first phase was almost over in the month of February 2021 in India, but soon after second wave emerged out with greater impact. The whole world is struggling hard to contain the spread of virus but finding it difficult, as new mutations and variants are taking shape continuously. Many mathematical models have been designed to predict spread of COVID-19, but prediction fails due to evolution of virus as well as its behavior. WHO provided many guidelines to prevent spread of COVID-19 which includes social distancing, wearing of masks in public places and frequent sensitization of hands. Wearing of mask has been proved to be the most effective in preventing the spread of corona virus. Wearing masks perhaps is the most important life style change which could help contain the spread of virus specially in offices, malls, theaters, restaurants and other public places. Though the administration frequently issues guidelines to wear masks but it is really very difficult to identify the peoples without mask in large gatherings. In the present manuscript, an automatic mask detection system has been proposed using machine learning to automatically identity the people without masks. © 2021 IEEE.
ABSTRACT
Purpose: We describe short-term outcomes as well as peri- and post-transplant complications in patients with prior coronavirus disease 2019 (COVID-19) who subsequently underwent kidney transplantation. Methods: This was a single-center, retrospective cohort study of all recipients of isolated living- or deceased-donor kidney transplants between 4/1/2020-10/1/2020. Patients with prior PCR confirmed COVID-19 were considered candidates for kidney transplantation if they were at least 4 weeks post-infection, had resolution of symptoms, and had one negative nasopharyngeal PCR swab specimen. Standard doses of induction and maintenance immunosuppression were administered at the time of transplant and included anti-thymocyte globulin, tacrolimus, mycophenolate, and tapering corticosteroids. Patients were followed from the date of transplantation until study conclusion (11/1/2020), to compare short-term patient and allograft outcomes between those with prior COVID-19 and COVID-19 naïve controls transplanted during the same time-period. Results: 81 patients received isolated kidney transplants during the review period, 13 (16.0%) of whom had recovered from prior COVID-19 infection. The median time between COVID-19 diagnosis and transplantation was 71 (IQR=56.5-135) days, and all 10 patients who were tested had evidence of significant antibody titers to the SARS-CoV-2 spike protein. The majority of patients had mild disease (69.2%), while 3 patients required hospital admission and supplemental oxygen, and 1 patient required mechanical ventilation. Baseline characteristics were similar between COVID-19 positive and negative patients, with the exception of more Hispanic/ Latino patients in the prior COVID-19 group (53.8% vs 17.6%;p<0.01). At study conclusion, after a median follow-up of 3.6 months, patient and allograft survival were similar between COVID-19 positive and negative patients (92.3%/92.3% vs 100.0%/98.5%), and mean baseline serum creatinine was 1.5 mg/dL in both groups. One patient with prior mild COVID-19 died due to a pulmonary embolism within 1-month of transplant;however, no differences were observed in the overall rate of thromboembolism (7.7% vs 4.4%;p=0.61). Index hospital length of stay and readmission rate within 30-days of transplant were also similar between groups, but patients with prior COVID-19 did have a higher incidence of delayed extubation posttransplant (15.4% vs 1.5%;p=0.02). No cases of COVID-19 re-infection or biopsy proven allograft rejection were observed among patients with prior COVID-19. Conclusions: In our preliminary experience, patients with prior COVID-19 infection appeared to have similar short-term outcomes when compared with COVID-19 naive patients. We did observe a potential signal for increased peri-operative respiratory complications in patients with prior COVID-19, which may warrant additional monitoring and further study in multi-center cohorts.
ABSTRACT
AIMS: Limb and patient outcomes in people with diabetic foot complications including diabetic foot ulcer (DFU) provided virtual triage and personalized video consultations during COVID-19 pandemic are not known. METHODS: Patients with foot complications attending the diabetic foot clinic prior to lockdown who sought teleconsultations during COVID-19 lockdown underwent virtual triage to include clinical history, visual inspection of feet, domiciliary wound care (community nurse assisted dressings) and offloading instructions. The subsequent ulcer, limb and mortality outcomes during the following 24 weeks of COVID-19 lockdown (April-September 2020, group 1) were assessed and compared with those who attended foot clinic during the same period in 2019 (April-September, group 2). RESULTS: Group 1 included 561 participants with foot complications provided with teleconsultations, median age 57 (51 to 63) years and diabetes duration of 10 (5 to 16) years. Twelve patients with severe DFU were excluded and 549 patients [357 (65%) neuropathic foot, 104 (18.9%) ischemic foot and 88 (16%) chronic Charcot foot with deformities] were evaluated. There were 227 (41.3%) participants with active DFU at start of lockdown, 32 (5.8%) with new onset ulcer during lockdown (47.1%) and 290 patients without ulcers. Group 2 included 650 participants; active foot ulcer was present in 366 patients. Wound closed or reduced in area in 78.4% of participants of group 1 compared to 76.0% (p = 0.318) in group 2. Fourteen (5.4%) patients required amputations [3 major and 11 minor] in group 1 during the study period compared to 6.8% in group 2 (p = 0.191). Twenty-one (3.8%) and 28 (4.3%) patients died (p = 0.532) during 24 weeks of follow up in group 1 and 2, respectively. CONCLUSIONS: Targeted foot-care service through virtual triage and teleconsultations during COVID-19 pandemic for people with foot complications have similar ulcer and limb outcomes compared to face-to-face foot care delivery.
