ABSTRACT

Background and aims: We studied use of do not resuscitate (DNR) orders in the Brain Attack Surveillance in Corpus Christi (BASIC) study before and during the COVID-19 pandemic. Methods: All hospitalized stroke cases were ascertained in Nueces County, Texas, USA during an equal time period before the pandemic (January, 2019-Feb, 2020) and during the pandemic (March, 2020-April, 2021). We compared use of DNR orders before and during the pandemic using logistic regression adjusted for demographic and clinical variables including initial stroke severity (NIHSS score). Nueces County is geographically isolated making complete case capture likely. Cases were validated by stroke physicians using source documentation. Results: There were more cases during the pandemic (N=716) than pre-pandemic (N=681). Median NIHSS score was 5 (IQR 9) during the pandemic and 4 (IQR 9) pre-pandemic (p=0.03). During the pandemic 18.0% of stroke patients had DNR orders compared with 13.3% prepandemic (p=0.016). Other demographic and risk factors were similar in the two time periods. In models adjusted for age, sex, race-ethnicity, NIHSS score, diabetes, hypertension, current smoking and stroke history, DNR orders were not more common in the pandemic compared with pre-pandemic (p=0.2), but stroke severity (NIHSS score) remained significantly higher during the pandemic (p<0.01). Conclusions: In this population-based study, greater use of DNR orders were seen during the pandemic than before the pandemic. The greater use of DNR orders may be due, in part, to the worse stroke severity presenting to hospitals during the pandemic.

ABSTRACT

Background and Objectives: The recently discovered coronavirus, SARS-CoV-2 has infected over 170 million people (as of 31th May 2021) since it was elucidated in December 2019. The number of SARS-CoV-2 cases and mortality rates vary from country to country, and unfortunately, the United Kingdom ranks in the top 5 countries with the most deaths as of 31th May 2021. Methods: A literature review was conducted during May 2021 to examine if factors such as gut microbiome, ethnic diversity, high cancer rates, obesity and alcohol consumption may have contributed to the higher number of cases and mortality due to SARS-CoV-2 in the UK. Results: The western diet is associated with a less diverse gut microbiome, as well as obesity, and contributes to the severity of SARS-CoV-2 infection. Moreover, people belonging to Black and South Asian ethnic groups in the UK have an increased risk of death due to SARS-CoV-2 infection. Given the high number of cancer patients in the UK, as well as excess consumption of alcohol, higher mortality rates were observed, most likely due to people possessing a less diverse gut microbiome and/or weakened immune system. Conclusion: Targeting the gut microbiome in developing potential therapeutics against SARS-CoV-2 is of value, and further studies are needed to understand the specific role of the gut microbiome. © 2022 Siddiqui et al.

ABSTRACT

AIM: Endoscopic Ultrasound (EUS) is well-established mode of intervention for tissue acquisition in solid organs with rapid on-site evaluation (ROSE). In the Covid-19 era implementation of infection control mechanisms has led modified hybrid technique to get high diagnostic yield for tissue sampling. Combination of Covid-19 SOPs and tissue acquisition method outline this hybrid technique to get high diagnostic Yield.We share our initial experience of EUS cases performed with this approach without ROSE. METHODS: All 84 cases who underwent EUS guided biopsy from June 2020 till December 2021 were included. The Procedure was done in a negative pressure room with all SOPs as per institutional guidelines for patient and staff safety with a minimum number of persons during procedure. RESULTS: Among these cases, 55 were male, mean age 56 years (range 22-90), Mean duration of procedure 25 min mean (10-90 min). 63 came for organ targeted for malignant pathology include pancreas 35, liver 02, lymph nodes 17, subepithelial lesions 06, mediastinal lesions 08, common-bile duct/gall bladder 04. 17 cases had a multi-targeted biopsy for the additional staging of disease. The number of 'passes' with the needle was average 02 with single pass 17, two pass 39, three passes 11, multitarget single pass in 17. Needle size (Franseen design) used for procedures was 22G in 78 cases and 25G in 6. Common tissue diagnoses include pancreatic adenocarcinoma 26, neuroendocrine tumours 04, tuberculosis 05, gastrointestinal stromal tumours 02, leiomyoma 03, lymphoma 03, metastatic renal cell carcinoma 04, squamous cell carcinoma 04, cholangiocarcinoma/ gall bladder adenocarcinoma 07, Sarcoma 02 and solid pseudopapillary epithelial neoplasm of pancreas (SPEN) 01. There were no immediate or early complications in all cases. CONCLUSIONS: Hybrid EUS in Covid 19 Era has emerged as a useful/cost-effective and safe approach to get tissue yield without the need for ROSE.

ABSTRACT

AIM: Enteroscopy is an endoscopic procedure to approach the small intestine in order to diagnose and treat various pathologies. The aim of this study is to share the experience of our center with this modality and highlight the main indications and diagnostic yield pf the procedure. METHODS: This is a single center retrospective study at Aga Khan University Hospital Karachi, Pakistan in which we included all the enteroscopies done in last five years. RESULTS: A total of 37 enteroscopies were done in past five years, the numbers has reduced significantly in the Covid-19 era. The mean age was 50.4 ± 16.5 years with 19 (51.4%) females and 18 (48.6%) males. The most common indications were jejunal thickening on CT scan 17 (45.9%) followed by obscure gastrointestinal bleeding 7 (18.9%) and chronic diarrhea 5 (13.5%). Most of the enteroscopies showed no gross pathology 17 (45.9%). However, jejunal ulcers 6 (16.2%), arteriovenous malformations 4 (10.8%), jejunal polyps 3 (8.1%), erythematous mucosa 2 (5.4%), pale mucosa 2 (5.4%), jejunal mass 2 (5.4%) and gastric polyp 1 (2.7%) are the findings noticed in rest of the enteroscopies performed. In 18 (48.6%) no biopsies were taken due to normal findings. 12 (32.4%) had nonspecific chronic inflammation in the jejunum. The remaining seven patient's histopathology showed giardiasis, MALTOMA, high grade B cell lymphoma, moderately differentiated adenocarcinoma, inflammatory polyp, hamartomatous polyp and adenomatous polyp. CONCLUSIONS: We shared the five year experience of enteroscopies done in our center which belongs to a low income country. The number of enteroscopies has greatly affected by the cost, low socioeconomic status of patients. Covid-19 has further reduced the number of diagnostic procedures in general. Most of the enteroscopies didn't reveal significant findings however there are cases where lymphoma and adenocarcinoma has been diagnosed.

ABSTRACT

Acanthamoeba is a free-living amoeba that has been found on surfaces, air, water and various environmental sources around the world. It enters the human body through the respiratory tract via the nose. Of note, amoebae are well known to act as a reservoir for various pathogenic microorganisms including bacteria and viruses such as Adenoviruses and Mimivirus. Given that SARS-CoV-2 of the Coronaviridae family is transmitted through the respiratory tract, and the Trojan horse nature of Acanthamoeba, it has been suggested that amoebae act as a vector in the transmission of SARS-CoV-2. The aim of this study was to provide an opinion of the possibility of the coexistence of Acanthamoeba with SARS-CoV-2.

ABSTRACT

The COVID-19 outbreak has affected dentists all over the world, including those in the Pakistan. It has had a huge impact on the practice of dental professionals as they are in direct contact with oral and nasal secretions of patients in the field. We conducted this study to find out how dental practitioners felt about the outbreak and how they believed it will affect the dental profession. To assess the impact of COVID-19 outbreak in Pakistan an exploratory cross-sectional study of dental professionals was conducted. Self-administered questionnaires were distributed to consenting participants between October and December 2021 via an online data collection platform (Google forms). These questionnaires were to collect the data about the understanding and awareness about the pandemics impact on respondent’s sociodemo graphics and psychological health. The data analysis in this study was done using the Statistical Package for the Social Sciences (SPSS) version 20. The study included 118 dental practitioners from the Pakistan, with an average age of 39.25 years and a majority of the participants were males. COVID 19 was determined to be well-understood by nearly 91 (77.1 %) respondents. COVID-19 was of the grave concern for more than half of the participants, 64 (54.24%), with the danger of catching the virus in the dentistry clinic being the most concerning cause of concern 64 (54.24%). It is concluded that the dental practitioners had an excellent awareness about the epidemiology, diagnosis, prevention, and treatment of COVID-19.

ABSTRACT

Introduction: Across the globe the healthcare system was severely affected by Coronavirus Disease-19 (COVID-19) pandemic. Measures taken to curtail the spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus have severely affected the paediatric patients presenting with Acute Appendicitis (AA). Aim: To assess the impact of COVID-19 on paediatric Acute Appendicities patients at tertiary care center in New Delhi. Materials and Methods: A retrospective analysis of patient demographics, symptomatology including delay in presentation to hospital, haematological, intraoperative findings and complications of all paediatric AA patients who underwent appendectomy from 23rd March 2020 to 22nd July 2020 (Pandemic Group- PG group) were performed. Patients presenting in corresponding time period in the year 2019 were also compared (Non Pandemic Group (NPG) group). Group comparisons for continuously distributed data were made using Independent sample t-test. For non normally distributed data, non parametric tests in the form of Wilcoxon test were used. Chi-squared test was used for group comparisons for categorical data. Results: A total of 72 patients were included with 39 in NPG and 33 in PG group respectively. There were no significant differences between the two groups in terms of age (p-value=0.759) and sex distribution (p-value=0.93). Patients in PG group had higher leukocyte counts as compared to NPG group (16748.48 +/- 7744.08 vs 12510.26 +/- 7736.58, p-value <0.007). There was no significant difference in delay in presentation, symptomatology, duration of hospital stay and postoperative complications rate between the two groups. Conclusion: There has been no significant change in the number of patients presenting with AA and the symptomatology during COVID-19 pandemic.

ABSTRACT

The public health threat posed by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has persisted since December 2019. Many countries were able to manage SARS-CoV-2 due to various strategies, like masking, social distancing, and vaccinations. Virus mutations are one of the most significant barriers to the disease's eradication;as a result, various variants have emerged (Alpha, Beta, Gamma, Delta, etc.) from time to time with higher mortality. Omicron, a variant identified from South Africa, has put the world on high alert. In this context, we have reviewed some reports on Omicron along with other variants. This new variant has been designated as a variant of concern by the World Health Organization. The preliminary reports revealed that Omicron is heavily mutated with more than 30 mutations (A67V, del69-70, T95I, del142-144, Y145D, etc.) in its spike protein. Despite vaccination with the most efficacious Pfizer candidate, Omicron infection was reported in South Africa. Bioactive lipids, such as arachidonic acid, alpha-linolenic acid, docosahexaenoic acid, eicosapentaenoic acid, and others have been reported to be the key components in inactivating the virus, so their future role is imperative. Ongoing research for the development of new or modification of existing vaccines must continue. © 2022. Acharya Balkrishna et al. All Rights Reserved.

ABSTRACT

Traditionally, convolutional neural networks need large amounts of data labelled by humans to train. Self supervision has been proposed as a method of dealing with small amounts of labelled data. The aim of this study is to determine whether self supervision can increase classification performance on a small COVID-19 CT scan dataset. This study also aims to determine whether the proposed self supervision strategy, targeted self supervision, is a viable option for a COVID-19 imaging dataset. A total of 10 experiments are run comparing the classification performance of the proposed method of self supervision with different amounts of data. The experiments run with the proposed self supervision strategy perform significantly better than their non-self supervised counterparts. We get almost 6% increase on average with self supervision compared to no self supervision, and more than 8% increase in accuracy in our best run with self supervision when compared to no self supervision. The results suggest that self supervision can improve classification performance on a small COVID-19 CT scan dataset.

ABSTRACT

Introduction: Improving peri- and postnatal facility-based care in low-resource settings (LRS) could save over 6000 babies' lives per day. Most of the annual 2.4 million neonatal deaths and 2 million stillbirths occur in healthcare facilities in LRS and are preventable through the implementation of cost-effective, simple, evidence-based interventions. However, their implementation is challenging in healthcare systems where one in four babies admitted to neonatal units die. In high-resource settings healthcare systems strengthening is increasingly delivered via learning healthcare systems to optimise care quality, but this approach is rare in LRS. Methods: Since 2014 we have worked in Bangladesh, Malawi, Zimbabwe, and the UK to co-develop and pilot the Neotree system: an android application with accompanying data visualisation, linkage, and export. Its low-cost hardware and state-of-the-art software are used to support healthcare professionals to improve postnatal care at the bedside and to provide insights into population health trends. Here we summarise the formative conceptualisation, development, and preliminary implementation experience of the Neotree. Results: Data thus far from similar to 18 000 babies, 400 healthcare professionals in four hospitals (two in Zimbabwe, two in Malawi) show high acceptability, feasibility, usability, and improvements in healthcare professionals' ability to deliver newborn care. The data also highlight gaps in knowledge in newborn care and quality improvement. Implementation has been resilient and informative during external crises, for example, coronavirus disease 2019 (COVID-19) pandemic. We have demonstrated evidence of improvements in clinical care and use of data for Quality Improvement (QI) projects. Conclusion: Human-centred digital development of a QI system for newborn care has demonstrated the potential of a sustainable learning healthcare system to improve newborn care and outcomes in LRS. Pilot implementation evaluation is ongoing in three of the four aforementioned hospitals (two in Zimbabwe and one in Malawi) and a larger scale clinical cost effectiveness trial is planned.

ABSTRACT

As construction projects resume worldwide and workers return to the job site, the possibility of transmitting the Covid-19 could be added to the extensive list of risks confronting workers in the construction sites;thus, the workers need to work alone in an assigned activity. Many workers are already working alone in the construction sites, such as utility workers, repair technicians, teleworkers, operators, and drivers. Lone workers in construction are subjected to greater safety risks compared with those working alongside others. Considering the accidents faced by lone workers, it’s less likely that another person would be there to aid them - and if they don’t get treatment quickly enough, serious injuries might prove deadly. Currently, the construction sites depend on physical inspections to the construction sites and manual observation of video streams generated through close circuit television (CCTV). To solve this issue, this research work presents an automated deep learning-based fall detection system of a lone worker to provide information of severe situations and help the workers in their golden time. A diverse dataset of multiple scenarios having workers with the excavator, forklift, ladder, and mobile scaffold is established, and a deep learning algorithm has been trained to validate the concept. The developed system is expected to reduce the efforts being made in manual inspection, enhance the timely access of the due aid from co-workers and supervisors, which is more easily obtainable in non-lone working situations. © 2021 Proceedings of the International Symposium on Automation and Robotics in Construction.
