ABSTRACT

The Royal College of Obstetrics and Gynaecology advocated replacing OGTT with HbA1c for gestational diabetes (GDM) screening for women with risk factors during the Covid-19 pandemic. HbA1c >=48mmol/mol/random plasma glucose (RPG) >=11.1mmol/l at booking indicated diabetes, and 41-47mmol/ mol/9-11mmol/ l prediabetes or possible GDM. Testing was repeated at 26 weeks if normal previously, with HbA1c >=39mmol/mol, fasting PG >=5.6mmol/l, or RPG >=9mmol/l diagnostic for GDM. A) At her clinic booking visit at 10 weeks gestation, 36 year-old South Asian female had HbA1c 55mmol/mol/RPG 9.5mmol/l suggesting undiagnosed type 2 diabetes. Initially managed with dietary advice and home blood glucose monitoring, metformin was added when self-monitored glucose above pregnancy targets (fasting and pre-meal <5.3mmol/l or 1 h post meal <7.8mmol/l) but insulin was required later. Metformin and insulin were stopped after delivery at 38 weeks with HbA1c 50mmol/mol three months postpartum, supporting the earlier diagnosis of type 2 diabetes. B) 32 year-old White Caucasian female was screened for GDM on booking at 11 weeks as BMI 38 kg/m2. HbA1c 44mmol/mol and RPG 6.9mmol/l confirmed GDM which was managed by dietary/lifestyle changes with glucose and pregnancy targets achieved until 28 weeks when metformin added. Normal delivery at 40 weeks with HbA1c 40mmol/mol three months postpartum triggered advice on long-term dietary/lifestyle changes and annual HbA1c checks. HbA1c was useful during the pandemic but most centres reverted to OGTT for GDM screening due to a significant fall in diagnoses using HbA1c >=39mmol/mol at 26 weeks. But, HbA1c testing was advantageous at booking to diagnose type 2 diabetes earlier.

ABSTRACT

The recent Covid-19 pandemic has created many challenges and barriers in healthcare, which includes the treatment and management of patients with type 2 diabetes (Robson & Hosseinzadeh, 2021). The purpose of this Evidence-Based Project (EBP) project is to evaluate the effectiveness of type 2 diabetes management through telehealth and answers the following PICOT question: In patients with diabetes type 2 who have difficulties with medical visit compliance (P), will the telehealth platform (I), compared to patient's previous visit HbA1c (C) improve the Hemoglobin A1c (HbA1c) diagnostic marker (O) over a 12-week period(T)? An extensive literature search of five databases was performed, citation chasing, and a hand search yielded fourteen pieces of evidence ranging from level I to VI (Melnyk & Fineout-Overholt, 2019). The pieces of evidence selected for this project support the evidence that telehealth implementation is as effective as the "usual care" or in-person visits to treat type 2 diabetes. The John Hopkins Nursing Evidence-Based Practice (JHNEBP) model was selected. Patients with a HbA1c of greater than 6.7% have been asked to schedule two six-week telehealth visits. During the live video visit, a review of medications, and diabetes self-management education (DSME) will be conducted. Participants will be provided with education to promote lifestyle modifications. The visits will be conducted through an Electronic Medical Record (EMR) system that is Health Insurance Portability and Accountability Act (HIPAA) compliant. A paired t-Test will be used with the data collected from the pre-and post-HbA1c. Improve the management of type 2 diabetes with the incorporation of telemedicine in primary care. Research supports the need to further expand the use of telehealth in primary care, to improve patient outcomes and decrease co-morbidities related to type 2 diabetes.

ABSTRACT

Physical inactivity is becoming an important threat to public health in today's society. The COVID-19 pandemic has also reduced physical activity (PA) levels given all the restrictions imposed worldwide. In this work, physical activity interventions supported by mobile devices and relying on control engineering principles were proposed. The model was constructed relying on previous studies that consider a fluid analogy of Social Cognitive Theory (SCT), which is a psychological theory that describes how people acquire and maintain certain behaviors, including health-promoting behaviors, through the interplay of personal, environmental, and behavioral factors. The obtained model was validated using secondary data (collected earlier) from a real intervention with a group of male subjects in Great Britain. The present model was extended with new technology for a better understanding of behavior change interventions. This involved the use of applications, such as phone-based ecological momentary assessments, to collect behavioral data and the inclusion of simulations with logical reward conditions for reaching the behavioral threshold. A goal of 10,000 steps per day is recommended due to the significant link observed between higher daily step counts and lower mortality risk. The intervention was designed using a Model Predictive Control (MPC) algorithm configured to obtain a desired performance. The system was tested and validated using simulation scenarios that resemble different situations that may occur in a real setting.

ABSTRACT

Background: During the coronavirus disease 2019 (COVID-19) pandemic, established best practices in cancer care were modified to diminish the risk of COVID-19 infection among patients and health-care workers. Objective(s): We aimed to study the modifications in cancer-directed therapy during the first wave of the COVID-19 pandemic. Material(s) and Method(s): A cross-sectional study of patients with cancers of the head and neck, thoracic, urologic, and central nervous systems who visited the medical oncology department of the Tata Memorial Hospital, Mumbai, India, between April 22, 2020 and June 01, 2020, was conducted. Data were prospectively collected in an online pro forma and supplemented from the electronic medical records. Result(s): Of a total of 514 patients, 363 (71%) were men. The most common malignancy was lung cancer in 234 patients (46%). Cancer-directed therapy was modified in 83 patients (16%). Deviations consisted of modification of the chemotherapy regimen (48%), temporary discontinuation of chemotherapy in 37%, and interim chemotherapy to delay surgery in 5%. Changes in the chemotherapy regimen included a shift to a less intensive regimen in 45%, changing from intravenous to oral in 40%, and less frequent dosing of immunotherapy in 7%. Considering missed appointments as a deviation from planned cancer therapy, 68% of patients had a deviation in the standard planned cancer care. Conclusion(s): Almost two-thirds of the patients could not reach the hospital during the COVID-19 pandemic lockdown in India. Of those who could reach the hospital, one of out every six patients with cancer had a change in their cancer-directed treatment, half of which consisted of a modification in the standard chemotherapy regimens. The effects of these therapy deviations are likely to be long-lasting.

ABSTRACT

Background & Aim: The pro-angiogenic, immunoregulatory and anti- inflammatory properties of MSCs are being exploited for the development of cellular therapies, including the treatment of graft versus host disease (GvHD), inflammatory bowel disease and COVID-19. SNBTS have developed a GMP process to bank umbilical cord MSCs (UC-MSCs) whereby we can reliably bank 100 vials of 10 million P2 UC-MSCs per cord. Each of these vials can be extensively expanded and stored for specific applications. The ultimate aim of the bank is for off-the-shelf clinical use, e.g., in GvHD or as an adjuvant therapy in Islet transplantations. Methods, Results & Conclusion(s): During process development, different basal media and supplements were screened for proliferation and MSC marker expression. Cells grown in promising media combinations were then tested for tri-lineage differentiation (identity), their chemokine/cytokine expression and T-cell inhibition (function) assessed. Medium selected for further GMP development and scale up was ultimately determined by all round performance and regulatory compliance. GMP-like UC-MSCs were shown to have immune-modulatory activity in T-cell proliferation assays at 4:1 or 16:1 ratios. Co-culture of UC-MSCs and freshly isolated leukocytes, +/- the immune activating agent LPS, show a dose dependent survival effect on leukocytes. In particular, neutrophils, which are normally very short lived in vitro demonstrated increased viability when co-cultured with UCMSCs. The survival effect was partially reproduced when UC-MSC were replaced with conditioned medium or cell lysate indicating the involvement of soluble factors. This improved neutrophil survival also correlates with results from leukocyte migration studies that demonstrate neutrophils to be the main cell type attracted to MSCs in in vitro and in vivo. Genetic modification of UC-MSC may improve their therapeutic potential. We have tested gene editing by CRISPR/Cas9 technology in primary UC-MSCS. The CXCL8 gene, highly expressed in UC-MSC, was targeted in isolates from several different donors with editing efficiencies of 78-96% observed. This translated to significant knockdown of CXCL8 protein levels in resting cells, however after stimulation levels of CXCL8 were found to be very similar in edited and non-edited UC-MSCs. This observation requires further study, but overall the results show the potential to generate future banks of primary UC-MSCS with genetically enhanced pro-angiogenic, immunoregulatory and/or anti-inflammatory activities.Copyright © 2023 International Society for Cell & Gene Therapy

ABSTRACT

Background. Surveys on Public Knowledge, Attitude, and Practice (PKAP) have been conducted in various countries with respondents from the public as well as health workers. Measuring the knowledge of the public about COVID-19 is very important to determine the knowledge gap among the public and also as an evaluation of the preventive efforts for COVID-19. Objective. The purpose of this research was to determine whether education level is a factor that affects one's literacy about COVID-19. Materials and Methods. This is cross-sectional research with online-based data collection using the Kobo toolbox application. The data collection was carried out from the 19th of April until the 2nd of May 2020. The number of people under study is 792. The level of knowledge was measured using 12 research questions with true or false question types. the multivariable logistic regression was carried out. Results. Most of the respondents (52.5%) were in the young age group (15-35 years old), were male (57.3%), and had a bache-lor or diploma education level (62.1%). Furthermore, most of the respondents had good knowledge (65.4%). The higher the respon-dents' educational level means, the better knowledge they had concerning COVID-19 (P=0.013). Conclusions. Public knowledge about COVID-19 is affected by their level of education. A good level of knowledge about COVID-19 was found among respondents with master's and doctoral degrees. This finding can contribute to the prevention of COVID-19, in which the priority of educating communities about COVID-19 should be given to those having an educational level below a master's degree.Copyright © the Author(s), 2023.

ABSTRACT

Air pollution, climate and population health are closely related in terms of their impacts on respiratory health and lung cancer. Air pollutants contribute to the exacerbation of chronic respiratory problems such as COPD and asthma. Air pollutants are also toxic and carcinogenic, initiating and promoting lung cancer development. Climate change in relation to environmental pollution affects the geographical distribution of food supply and diseases such as pneumonia in adults and children. The threat of air pollution, and hence global warming and climate changes, and their effects on population and respiratory health, is an imminent threat to the world and deserves immediate and sustainable combating strategies and efforts. The goals are to increase public awareness and engagement in action, with alignment of international collaboration and policy, and with steering towards further research. Now is the prime time for international collaborative efforts on planning and actions to fight air pollution and climate change before it is too late.Copyright © ERS 2021.

ABSTRACT

It is known that inflammatory cytokines exacerbate the persistence and severity of various disease states. Breast cancer is the most frequently detected cancer among women worldwide and our recent studies suggest that the inflammatory state of breast (BrCa) cancer, a byproduct of elevated cytokine expression, induces epigenetic modifications leading to increased recurrence. Ongoing NCI clinical trial data (ClinicalTrials.gov, CCC19, NCT04354701) indicates that among patients with cancer and COVID-19, the mortality is high, and the most prevalent malignancies are of breast [21%] and prostate [16%] origin. Due to the risk of cytokine storm during SARS-CoV-2 infection, it is crucial to identify potential mechanisms of hyperinflammation in BrCa patients. In this study, we have evaluated the level of copy number alteration (CNA) of different inflammatory cytokines including IL-8, IL-1b, IL6, IL-8, GM-CSF, TNF-alpha and many others using cBioportal platform which includes over sixty-nine thousand tumor samples (n>69,000 from 213 different studies) from over 33 different cancers. We found that IL-8 has the highest level of amplification in different breast cancers subtypes. Besides, we also analyzed serum samples from BrCa patients, both recurrent and non-recurrent, by different proteomics methods to identify serum cytokines involved in prognosis and recurrence. Comparative data analysis between non-recurrent BrCa against recurrent BrCa patients identified several proteins with very high significance, mostly proteins associated with epigenetic pathways including HDAC9 (P = 0.0035), HDAC5 (P = 0.013), and HDAC7 (P = 0.020). Besides, we identified differential expression of several pro-inflammatory cytokines and immune regulators (IL-8, IL-4, IL-18, IL-12p70) that were present only in recurrent BrCa patient serum. Our data indicate that inflammatory processes contribute to epigenetic modifications that ultimately play a critical role in breast cancer recurrence. In terms of COVID-19 associated co-morbidity, the already dysregulated inflammatory state of BrCa patients may increase their susceptibility to cytokine-storm, leading to increased severity of COVID-related complications and increased mortality rate. Specifically, we hypothesize that the identified elevated level of IL-8 in BrCa patients may lead to a higher basal level of inflammation and contribute to the risk of attaining cytokine-storm during SARS-CoV-2 infection, making it a valuable target for future studies.

ABSTRACT

CD4+CD25+FOXP3+regulatory T cells (Tregs) contribute to the maintenance of immune homeostasis and tolerance in the body. The expression levels and functional stability of FOXP3 control the function and plasticity of Tregs. Tregs critically impact infectious diseases, especially by regulating the threshold of immune responses to pathogenic microorganisms. The functional regulatory mechanism and cell-specific surface markers of Tregs in different tissues and inflammatory microenvironments have been investigated in depth, which can provide novel ideas and strategies for immunotherapies targeting infectious diseases.Copyright © 2021.

ABSTRACT

Breast cancer (BC) is the most common cancer in Korean American (KA) women. In view of its high prevalence in these women, their low screening rates, and the cultural influence of BC risk factors in their lifestyles, we developed a community-based culturally tailored BC prevention program, the Korean Breast Cancer Risk Reduction Program (KBCRRP). Guided by the PRECEDE-PROCEDE and health belief models, the KBCRRP was developed to achieve four goals: (1) healthy weight, (2) physically active lifestyle, (3) healthy diet, and (4) BC screening and adherence. KBCRRP combines effective multicomponent strategies for BC screening and a group-based lifestyle intervention incorporating traditional Korean health beliefs and is tailored for BC risk reduction. In this paper, we provide an overview of the program, the process of program development, implementation, and evaluation, and modification during the COVID-19 pandemic. The initial program involved 8 weeks of in-person group education sessions led by interdisciplinary healthcare professionals and 16 weeks of follow-up involving smartphone applications, phone calls, and text messaging from trained lifestyle coaches. Participants received opportunities to obtain free mammography during the program. After feasibility testing, the program was modified by incorporating participants' feedback. During the COVID-19 pandemic, we provided the program using the Zoom video platform. Participants' recruitment and retention during the pandemic was successful, reflecting the fact that virtual delivery of group-based education was a feasible and acceptable alternative to in-person sessions. Collaboration with community organizations serving the target population is the key to developing and sustaining a successful community-based educational program.

ABSTRACT

<b>Background and Objective:</b> The COVID-19, which has been circulating since late 2019, is caused by SARS-CoV-2. Because of its high infectivity, this virus has spread widely throughout the world. Spike glycoprotein is one of the proteins found in SARS-CoV-2. Spike glycoproteins directly affect infection by forming ACE-2 receptors on host cells. Inhibiting glycoprotein spikes could be one method of treating COVID-19. In this study, the antivirus marketed as a database will be repurposed into an antiviral SARS-CoV-2 and the selected compounds will be modified to become organoselenium compounds. <b>Materials and Methods:</b> The research was carried out using <i>in silico</i> methods, such as rigid docking and flexible docking. To obtain information about the interaction between spike glycoprotein and ligands, MOE 2014.09 was used to perform the molecular docking simulation. <b>Results:</b> The analysis of binding energy values was used to select the ten best ligands from the first stage of the molecular docking simulation, which was then modified according to the previous QSAR study to produce 96 new molecules. The second stage of molecular docking simulation was performed with modified molecules. The best-modified ligand was chosen by analyzing the ADME-Tox property, RMSD value and binding energy value. <b>Conclusion:</b> The best three unmodified ligands, Ombitasvir, Elbasvir and Ledipasvir, have a binding energy value of -15.8065, -15.3842 and -15.1255 kcal mol<sup>1</sup>, respectively and the best three modified ligands ModL1, ModL2 and ModL3 has a binding value of -15.6716, -13.9489 and -13.2951 kcal mol<sup>1</sup>, respectively with an RMSD value of 1.7109 Å, 2.3179 Å and 1.7836 Å.

ABSTRACT

Obesity is one of the main severe COVID-19 risk factors. SARS-CoV-2 causes endothelitis that lead to inflammation and prothrombotic state. Also visceral adipose tissue is a source of different prothrombogenic and proinflammatory cytokines that make prognosis and survival of patients with COVID-19 worse. The synergy of the COVID-19 and obesity pandemics is a double blow to health, especially in young patients. Weight loss due to lifestyle modifications and vaccination are effective methods of the severe COVID-19 prevention in obese patients. This review presents the main pathogenetic aspects of cardiovascular disease development and progression in obese patients with COVID-19 and possible methods of adverse outcomes prevention in this group of patients.Copyright © 2022 Authors.

ABSTRACT

Introduction: Adopting diabetes self-care behaviors to control blood glucose is essential, but adherence to them has been challenged due to restrictions related to Covid-19. These restrictions have negatively impacted the psychosocial condition of individuals with diabetes, which could lead to poor self-care. Accordingly, this study aimed to explore the experiences of individuals with type 2 diabetes regarding self-care behaviors and diabetes management during the COVID-19 pandemic. Material(s) and Method(s): This qualitative study was conducted using conventional content analysis, the data of which were collected through interviews with people over 18 years of age with type 2 diabetes who were selected from the Endocrinology Clinic of Erfan Hospital in Tehran. Using telephone and WhatsApp, semi-structured interviews were conducted with 20 participants (15 women). Content analysis was done using the constant comparative method, and the open and axial coding method was applied. The data were manually coded, and the main themes and categories emerged from data. Result(s): Two main themes emerged from the data: 1) challenges and limitations toward diabetes self-care and 2) facilitators of efficient self-care. Challenges and limitations included 4 sub-themes: Inevitable lifestyle changes, psychosocial problems, limited/lack of access to health care services and medication, and adverse physical effects. Facilitators had 2 sub-themes: improved individual capability and maintaining social interaction. Conclusion(s): Our findings indicated that inevitable lifestyle changes, limited access to health care, and adverse psychosocial consequences were the most critical challenges for diabetes management during the COVID-19 pandemic. Improving stress management skills and effective coping strategies can facilitate the adoption of self-care behaviors.Copyright © 2022, Research Institute for Endocrine Sciences.

ABSTRACT

For German sociologist Ulrich Beck, risks in the contemporary world consist of three dimensions: ecological crises, financial crises, and the risk of global political extremism. While these risks make us realize that our daily lives are closely related to global political and economic fluctuations, they point us to new directions of conflicts and alliances. Given that our perception of risks is related to our political behavior towards them, no risks exist as themselves independent of our consciousness. Rather, only when being perceived, risks become socially and politically constructed to be defined, hidden, or performed strategically. The COVID-19 pandemic, or the globalizing coronavirus disease since 2019, is one of those risks. It poses a question about what kind of political subject exercises what politics to deal with this threatening risk. This chapter attempts to answer this question by investigating COVID-19 and governmental and public responses in Japan. It theorizes non-pharmaceutical interventions (NPIs) as a nexus of public health as bio-politics and spatial antivirus measures as geo-politics. After examining tensions between NPIs and other economic and democratic practices in Japan, this chapter elucidates the political implications of NPIs and forecasts Japanese society after the COVID-19 pandemic. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

ABSTRACT

SARS-CoV-2 infects human cells via binding of the viral spike glycoprotein to its main cellular receptor, angiotensin-converting enzyme 2 (ACE2). The spike protein-ACE2 receptor interaction is therefore a major target for the development of therapeutic or prophylactic drugs to combat coronavirus infections. Various engineered soluble ACE2 variants (decoys) have been designed and shown to exhibit virus neutralization capacity in cell-based assays and in vivo models. Human ACE2 is heavily glycosylated and some of its glycans impair binding to the SARS-CoV-2 spike protein. Therefore, glycan-engineered recombinant soluble ACE2 variants might display enhanced virus-neutralization potencies. Here, we transiently co-expressed the extracellular domain of ACE2 fused to human Fc (ACE2-Fc) with a bacterial endoglycosidase in Nicotiana benthamiana to produce ACE2-Fc decorated with N-glycans consisting of single GlcNAc residues. The endoglycosidase was targeted to the Golgi apparatus with the intention to avoid any interference of glycan removal with concomitant ACE2-Fc protein folding and quality control in the endoplasmic reticulum. The in vivo deglycosylated ACE2-Fc carrying single GlcNAc residues displayed increased affinity to the receptor-binding domain (RBD) of SARS-CoV-2 as well as improved virus neutralization activity and thus is a promising drug candidate to block coronavirus infection.
