Intermediate Results of the Research for Percutaneous and Surgical Treatment for Left Anterior Descending Artery Chronic Total Occlusion

Objective: Is to find out which revascularization methods have less of risk factors and complications after the surgery and long-term period. Method(s): From January 2018 to December 2019 were operated 134 patients with LAD CTO. 48 of them underwent MIDCAB: 36 (75%) males and 12 (25%) females;aged 58.7 +/-8.7;7 (14.6%) with previous diabetes;10 (20.8%) with previous PCI of LAD with drug-eluting stent. In the PCI group there were 86 patients: 52 (60.5%) males and 34 (39.5%) females;aged 64.8 +/-8.3;23 (26.7%) with previous diabetes. Result(s): Hospital mortality was 0 (0%) in MIDCAB unlike 1 (1.2%) in PCI. Myocardial infarction was 0 (0%) in both the groups. In MIDCAB the number of conversions to onpump and sternotomy was 0 (0%), there were 6 (12.5%) pleuritis with pleural puncture and 3 (6.2%) with long wound-aches. The hospitalization period was 10.7+/-2.9 days for MIDCAB and 9.9 +/-3.9 days for PCI. In the PCI group 2.0 +/-1.0 drug-eluting stents were used. In-hospital costs were higher for PCI 3809 unlike 3258 for MIDCAB. After one year in MIDCAB group died 2 (4.2%) patients, from noncardiac causes. In PCI group died 3 (3.5%) patients, all from cardiac causes. Because of pandemic COVID-19 were checked only 48 patients by angiography and general clinical examination: 25 after MIDCAB and 23 after PCI. 5 patients have a graft failure, caused by surgical mistakes. 4 patients have stents restenosis and 1 has LAD's reocclusion. Conclusion(s): Both methods of revascularization for LAD CTO are demonstrated similar results. EuroSCORE II (P = 0.008) and glomerular filtrating rate (P = 0.004) are significant potential risk factors for mortality in both groups, age is potential risk factor for graft failure (P = 0.05). Dyslipidemia is significant risk factor for LAD restenosis in PCI group (P = 0.02). MIDCAB is associated with lower incidence of revascularization repeat and in-hospital mortality in the literature data and it costs lower than PCI for LAD CTO as our study has shown.

Assessment of Jordanian physicians' knowledge about venous thromboembolism risk and management among COVID-19 patients

Objectives: The aim of this study was to assess Jordanian physicians' awareness about venous thromboembolism (VTE) risk among COVID-19 patients and its treatment protocol. Method(s): This was a cross-sectional-based survey that was conducted in Jordan in 2020. During the study period, a convenience sample of physicians working in various Jordanian hospitals were invited to participate in this study. Physicians' knowledge was evaluated and physicians gained one point for each correct answer. Then, a knowledge score out of 23 was calculated for each. Key Findings: In this study, 102 physicians were recruited. Results from this study showed that most of the physicians realize that all COVID-19 patients need VTE risk assessment (n = 69, 67.6%). Regarding VTE prophylaxis, the majority of physicians (n = 91, 89.2%) agreed that low molecular weight heparin (LMWH) is the best prophylactic option for mild-moderate COVID-19 patients with high VTE risk. Regarding severe/critically ill COVID-19 patients, 75.5% of physicians (n = 77) recognized that LMWH is the correct prophylactic option in this case, while 80.4% of them (n = 82) knew that mechanical prevention is the preferred prophylactic option for severe/critically ill COVID-19 patients with high bleeding risk. Moreover, 77.5% of physicians (n = 79) knew that LMWH is the treatment of choice for COVID-19 patients diagnosed with VTE. Finally, linear regression analysis showed that consultants had an overall higher knowledge score about VTE prevention and treatment in COVID-19 patients compared with residents (P = 0.009). Conclusion(s): All physicians knew about VTE risk factors for COVID-19 patients. However, consultants showed better awareness of VTE prophylaxis and treatment compared with residents. We recommend educational workshops be conducted to enhance physicians' knowledge and awareness about VTE thromboprophylaxis and management in COVID-19 patients.Copyright © 2022 The Author(s).

Nonlinear dynamics modeling and epidemic forecast of COVID-19

To study the spreading trend and risk of COVID-19, according to the characteristics of COVID-19, this paper proposes a new transmission dynamic model named SLIR(susceptible-low-risk-infected-recovered), based on the classic SIR model by considering government control and personal protection measures. The equilibria, stability and bifurcation of the model are analyzed to reveal the propagation mechanism of COVID-19. In order to improve the prediction accuracy of the model, the least square method is employed to estimate the model parameters based on the real data of COVID-19 in the United States. Finally, the model is used to predict and analyze COVID-19 in the United States. The simulation results show that compared with the traditional SIR model, this model can better predict the spreading trend of COVID-19 in the United States, and the actual official data has further verified its effectiveness. The proposed model can effectively simulate the spreading of COVID-19 and help governments choose appropriate prevention and control measures. Copyright ©2023 Control and Decision.

A study on the assessment of risk management performance in maritime start-ups: evidence from China

Due to the COVID-19 pandemic, the international shipping market has been highly volatile, posing a serious threat to the survival and development of many maritime start-ups. With the development of the digital economy, digital transformation is affecting the evolution and upgrading of many traditional enterprises, including maritime enterprises. In the post-COVID-19 era, start-up small and medium-sized enterprises will need to consider the importance of enterprise risk management to achieve transformation and upgrading. The purpose of this study is to provide guidance for the establishment and upgrading of risk management systems for start-ups based on the identification of risk management strategies of maritime enterprises and the evaluation of their performance. The fuzzy analytic hierarchy process and importance-performance analysis methods were used to rank the operational risk, financial risk, market risk, innovation risk, and disaster risk according to sub-items and screen out the risk management schemes for priority improvements. Through empirical research, it was found that the financial risk and market risk response schemes have the lowest performance and need to be prioritised for improvement. This study argues that start-ups can appropriately challenge their risk management strategies to meet potential risk management needs based on their own circumstances.

Evaluation of COVID-19 Vaccines in Primary Prevention Against Infections and Reduction in Severity of Illness Following the Outbreak of Sars-Cov-2 Omicron Variant in Shanghai

Objectives: To evaluate COVID-19 vaccines in primary prevention against infections and lessening the severity of illness following the most recent outbreak of the SARS-CoV-2 Omicron variant in Shanghai. Method(s): To investigate whether inactivated vaccines were effective in protecting against COVID-19 infections, we estimated the odds ratio (OR) of the vaccination in COVID-19 cases vs. matched community-based healthy controls. To evaluate the potential benefits of vaccination in lowering the risk of symptomatic infection (vs. asymptomatic), we estimated the relative risk (RR) of symptomatic infections among diagnosed patients. We also applied the multivariate stepwise Logistic regression analyses to measure the risk of disease severity (symptomatic vs. asymptomatic and moderate/severe vs. mild) in COVID-19 patient cohort with vaccination status as an independent variable while controlling for potential confounding factors. Result(s): Out of the 153,544 COVID-19 patients included in the analysis, 118,124 (76.9%) patients had been vaccinated and 143,225(93.3%) were asymptomatic patients. Of the 10,319 symptomatic patients, 10,031(97.2%), 281(2.7%) and 7(0.1%) experienced mild, moderate, and severe infections, respectively. There is no evidence that the vaccination helped protect from infections (OR=0.82, p=0.613). The vaccination, however, offered a small but significant protection against symptomatic infections (RR=0.92, p < 0.001) and halved the risk of moderate/severe infections (OR=0.48, 95% CI: 0.37 - 0.61). Older age (> 60 years) and malignant tumors were significantly associated with moderate/severe infections. Gender also appeared to be a risk factor for symptomatic infections, with females being associated with a lower risk for moderate/severe illness. Conclusion(s): Inactivated COVID-19 vaccines helped provide a small but significant protection against symptomatic infections and halved risk of moderate/severe illness among symptomatic patients. The vaccination was not effective in blocking COVID-19 Omicron variant community spread.Copyright © 2023

Updates of precision medicine in type 2 diabetes

Diabetes mellitus is prevalent worldwide and affects 1 in 10 adults. Despite the successful development of glucose-lowering drugs, such as glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose cotransporter-2 inhibitors recently, the proportion of patients achieving satisfactory glucose control has not risen as expected. The heterogeneity of diabetes determines that a one-size-fits-all strategy is not suitable for people with diabetes. Diabetes is undoubtedly more heterogeneous than the conventional subclassification, such as type 1, type 2, monogenic and gestational diabetes. The recent progress in genetics and epigenetics of diabetes has gradually unveiled the mechanisms underlying the heterogeneity of diabetes, and cluster analysis has shown promising results in the substratification of type 2 diabetes, which accounts for 95% of diabetic patients. More recently, the rapid development of sophisticated glucose monitoring and artificial intelligence technologies further enabled comprehensive consideration of the complex individual genetic and clinical information and might ultimately realize a precision diagnosis and treatment in diabetics.

Caesarean section in critically unwell peri-partum patients with COVID-19: A tertiary centre's experience

Introduction: The COVID-19 pandemic has required clinical teams to function with an unprecedented amount of uncertainty, balancing complex risks and benefits in a highly fluid environment. This is especially the case when considering the delivery of a pregnant woman critically unwell with COVID-19. This is one maternal critical care team's reflections on establishing best practice and a shared mental model when undertaking a Caesarean section in critically unwell patients with COVID-19. Objective(s): We describe our experience of balancing the risks and streamlining the process of this high-risk intervention. Method(s): We used our standard clinical governance forums across four specialties (Obstetrics, Intensive care, Anaesthetics and Neonatology) to identify key challenges and learning points. We developed a working group to combine our learning and develop a shared mental model across the involved teams. Result(s): 1. The decision to deliver must be multidisciplinary involving Obstetrics, Intensive care, Anaesthetics, Neonatology and the patient according to their capacity to participate. The existing structure of twice daily ITU ward rounds could be leveraged as a 'pause' moment to consider the need for imminent delivery and review the risk-benefit balance of continued enhanced pharmacological thromboprophylaxis. 2. We identified a range of scenarios that our teams might be exposed to: 3. Perimortem Caesarean section 4. Critically unwell - unsafe to move to theatre 5. Critically unwell - safe to move to theatre 6. Recreating an obstetric theatre in the ICU Advantages Avoids moving a critically unstable patient, although our experience is increasing moving patients for ECMO. Some forms of maximal non-invasive therapy such as High Flow Nasal Oxygen may require interruption to move to theatre with resultant risk of harm or be difficult to continue in transport mode through a bulky ICU ventilator e.g. CPAP Disadvantages Significant logistics and coordination burden: multiple items of specialist equipment needing to be brought to the ICU. Human factors burden: performing a caesarean section in an unfamiliar environment is a significant increase in cognitive load for participating teams. Environmental factors: ICU side rooms may offer limited space vs the need to control the space if performed on an open unit. Delivering a Neonate into a COVID bubble. Conclusion(s): Developing a shared mental model across the key teams involved in delivering an emergency caesarean section in this cohort of critically unwell patients has enabled our group to own a common understanding of the key decisions and risks involved. We recommend a patient centred MDT decision making model, with a structure for regular reassessment by senior members of the teams involved. In most circumstances the human factors and logistical burden of recreating an operating theatre in the ICU outweighs the risk of transport to theatre. Pre-defined checklists and action cards mitigate the cognitive and logistical burden when multiple teams do perform an operative delivery in ICU. Action cards highlight key aspects of routine obstetric care to be replicated in the ICU environment.

Exploring Social Media for Early Detection of Depression in COVID-19 Patients

The COVID-19 pandemic has caused substantial damage to global health. Even though three years have passed, the world continues to struggle with the virus. Concerns are growing about the impact of COVID-19 on the mental health of infected individuals, who are more likely to experience depression, which can have long-lasting consequences for both the affected individuals and the world. Detection and intervention at an early stage can reduce the risk of depression in COVID-19 patients. In this paper, we investigated the relationship between COVID-19 infection and depression through social media analysis. Firstly, we managed a dataset of COVID-19 patients that contains information about their social media activity both before and after infection. Secondly, We conducted an extensive analysis of this dataset to investigate the characteristic of COVID-19 patients with a higher risk of depression. Thirdly, we proposed a deep neural network for early prediction of depression risk. This model considers daily mood swings as a psychiatric signal and incorporates textual and emotional characteristics via knowledge distillation. Experimental results demonstrate that our proposed framework outperforms baselines in detecting depression risk, with an AUROC of 0.9317 and an AUPRC of 0.8116. Our model has the potential to enable public health organizations to initiate prompt intervention with high-risk patients. © 2023 ACM.

Dynamic Safety Assessment and Enhancement of Port Operational Infrastructure Systems during the COVID-19 Era

Seaports function as lifeline systems in maritime transportation, facilitating critical processes like shipping, distribution, and allied cargo handling. These diverse subsystems constitute the Port Infrastructure System (PIS) and have intricate functional interdependencies. The PIS is vulnerable to several external disruptions, and the impact of COVID-19 is severe and unprecedented in this domain. Therefore, this study proposes a novel general port safety framework to cope with recurring hazards and crisis events like COVID-19 and to augment PIS safety through a multi-state failure system. The PIS is divided into three critical subsystems: shipping, terminal, and distribution infrastructure, thereby capturing its functional interdependency and intricacy. A dynamic input-output model is employed, incorporating the spatial variability and average delay of the disruption, to determine the PIS resilience capacity under the stated disruptions. This study simulates three disruption scenarios and determines the functional failure capacity of the system by generating a functional change curve in Simulink. This study offers viable solutions to port managers, terminal operators, and concerned authorities in the efficient running of intricate interdependent processes and in devising efficient risk control measures to enhance overall PIS resilience and reliability. As part of future studies, given the difficulty in obtaining relevant data and the relatively limited validation of the current model, we aim to improve the accuracy and reliability of our model and enhance its practical applicability to real-world situations with data collected from a real-world case study of a PIS system.

The Application of PageRank model in urban epidemic prevention and control

The ongoing COVID-19 epidemic has had a great impact on social activities and the economy. The usage technical analysis tools to provide a more accurate and efficient reference for epidemic control measures is of great significance. This paper analyzes the characteristics and deficiencies of the existing technical methods, such as regression model, simulation calculation, differential equation and so on. By analyzing past outbreak cases and comparing the epidemic prevention measures of different cities, we discuss the importance of early and timely prevention in controlling the epidemic, and the importance of analyzing and formulating plans in advance. We then make the key observation that the spread of the virus is related to the topology of the urban network. This paper further proposes an epidemic analysis model of the optimized PageRank model, and gives a ranking algorithm for virus transmission risk levels based on road nodes, forming a visual risk warning level map, and applies the algorithm to the epidemic analysis of Yuegezhuang area in Beijing. Finally, more in-depth research directions and suggestions for prevention and control measures are put forward. © 2023 SPIE.

Anaesthetic pre-assessment of obese patients in obstetrics: challenges in COVID recovery

Introduction: One in five pregnant women in the UKis obese. Obesity is associated with increased risk of both maternal and foetal adverse outcomes. RCOG guidelines [1] recommend that all women with a booking BMI over 40 kg/m2 should be reviewed antenatally by a senior obstetric anaesthetist to guide risk assessment, medical optimisation and shared decision-making. The 2021 MBRRACE report [2] recommends that all women should be reweighed in the third trimester for accurate VTE risk scoring and prophylactic LMWH dosing. In our institution, reconfiguration of hospital areas as part of the COVID-19 response led to loss of designated clinic space for our obstetric anaesthetic clinic. As a result, our practice since has been to initially offer a telephone consultation followed by a face-to-face review if needed. Finding space for the latter has often been a significant logistical challenge. Our project sought to assess whether our practice continued to meet national standards in the wake of these changes. Method(s): Following audit approval, we retrospectively reviewed all women with a BMI >40 kg/m2 undergoing caesarean section (CS) over a six-month period (1/4/22 to 31/9/22). Result(s): 20 women met inclusion criteria (Category 1-3 CS - 12 women;Category 4 CS - 8 women). 100% of patients had booking height, weight and BMI recorded. 20% (4/20) of patients were reweighed in the 3rd trimester. Only 55% (11/20) of patients had been referred to and reviewed in the antenatal obstetric anaesthetic clinic (Figure). Of the 11 patients referred, 6 were referred later than 30 weeks. Of the 9 patients not referred, 8 had a BMI between 40 and 45 kg/m2. By contrast, 87% (6/7) of patients with BMI over 45 kg/m2 were referred and seen. Discussion(s): Our audit showed that we are not meeting national standards. Possible reasons identified were lack of awareness of the RCOG standards and referral criteria (especially for women with a BMI of 40 to 45 kg/m2) and logistical issues in undertaking face-to-face reviews without designated clinic space. Presentation of our results at the joint anaesthetic, obstetric and midwifery governance meeting has helped identify space in the antenatal clinic for face-to-face reviews, to start from March 2023 and to raise awareness of the national standards to ensure referral of all women with a BMI over 40 kg/m2. A reaudit is planned in 6 months. [Figure presented]Copyright © 2023 Elsevier Ltd

Association of SARS-COV-2 viral RNAemia, IL- 6 gene polymorphism, serum IL-6 and peripheral blood lymphocytes and monocytes with disease severity in COVID-19 patients

Coronavirus disease 2019 (COVID-19) is a fatal pandemic viral disease caused by the severe acute respiratory syndrome corona virus type-2 (SARS-CoV-2). The aim of this study is to observe the associations of IL-6, SARS-COV-2 viral load (RNAemia), IL- 6 gene polymorphism and lymphocytes and monocytes in peripheral blood with disease severity in COVID-19 patients. This study was carried out from March 2021 to January 2022. RT-PCR positive 84 COVID-19 patients and 28 healthy subjects were enrolled. Blood was collected to detect SARS-COV-2 viral RNA (RNAemia) by rRT-PCR, serum IL-6 level by chemiluminescence method, SNPs of IL-6 by SSP-PCR, immunophenotyping of lymphocytes and monocyte by flow cytometry. Serum IL-6 level (pg/ml) was considerably high among critical patients (102.02 +/- 149.7) compared to severe (67.20 +/- 129.5) and moderate patients (47.04 +/- 106.5) and healthy controls (3.5 +/- 1.8). Serum SARS-CoV-2 nucleic acid positive cases detected mostly in critical patients (39.28%) and was correlated with extremely high IL-6 level and high mortality (R =.912, P < 0.001). Correlation between IL-6 and monocyte was statistically significant with disease severity (severe group, p < 0.001, and 0.867*** and critical group p < 0.001 and 0.887***). In healthy controls, moderate, severe and critically ill COVID-19 patients, IL-6 174G/C (rs 1800795) GG genotype was 82.14%, 89.20%, 67.85% and 53.57% respectively. CC and GC genotype had strong association with severity of COVID-19 when compared with GG genotype. Significant statistical difference found in genotypes between critical and moderate groups (p < 0.001, OR-10.316, CI-3.22-23.86), where CC genotype was associated with COVID-19 severity and mortality. The absolute count of T cell, B cell, NK cell, CD4+ T cells and CD8+ T cells were significantly decreased in critical group compared to healthy, moderate and severe group (P < 0.001). Exhaustion marker CD94/NKG2A was increased on NK cells and CD8+ cytotoxic T cell among critical and severe group. Absolute count of monocyte was significantly increased in critical group (P < 0.001). Serum IL-6, IL-6 174 G/C gene and SARS-CoV-2 RNAaemia can be used in clinical practice for risk assessment;T cell subsets and monocyte as biomarkers for monitoring COVID-19 severity. Monoclonal antibody targeting IL-6 receptor and NKG2A for therapeutics may prevent disease progression and decrease morbidity and mortality.Copyright © 2023 Elsevier Inc.

Totally Percutaneus Veno-Venous ECMO Therapy for COVID 19 Patients. Bridge to Recovery or Lung Transplantation?

Objective: Multiple major health organisations recommend the use of extracorporeal membrane oxygenation (ECMO) support for COVID-19-related acute hypoxaemic respiratory failure. Method(s): From march 2020 to november 2021 we done 108 veno-venous ECMO therapies. 35 patients required implantation immediately in intensive care unit in place of call by mobile ECMO team. Depend from distance of call it was used medical ambulance, rescue helicopter or medical plane. Result(s): In the first analyzed period (March-December 2020), 90-day mortality was 41%. 8 (7.6%) patients were discharged from the Intensive Care Unit. The remaining 3 (4.2%) were discharged home. 7 patients (6.6%) had both lung transplants. 7 patients (6.6%) required conversion to VV-A ECMO therapy due to the development of acute heart failure. Conclusion(s): In the analyzed period of March-December 2020, the mortality was 41%. As a result, the lower effect of regression of consolidation and inflammatory lesions of lung tissue indicates that ECMO therapy remains the treatment method in high-risk patients as a bridge therapy to lung transplantation.

The temporal evolution in disease phenotype of COVID-19 hospitalisation, intensive care and case fatality rates in cancer patients across the United Kingdom (UKCCP)

Background: People living with cancer are reported to be at increased risk of hospitalization and death following infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This is proposed to be dependent on a combination of intrinsic patient and cancer factors such as cancer subtype, and emerging SARS-CoV-2 variants with differing pathogenicity. However, COVID-19 phenotype evolution across the pandemic from 2020 has not yet been systematically evaluated in cancer patients. Method(s): This study is a population-scale real-world evaluation of Coronavirus outcomes in the United Kingdom for cancer patients from 1st November 2020-31st August 2022. The cancer cohort comprises individuals from Public Health England's national cancer dataset, excluding individuals less than 18 years old. Case-outcome rates, including hospitalization, intensive care and casefatality rates were used to assess the evolution in disease phenotype of COVID-19 in cancer patients. Multivariable logistic regression models were fitted to compare risk of Coronavirus outcomes in the cancer cohort relative to the non-cancer population during the Omicron wave in 2022. Result(s): The cancer cohort comprised of 198,819 positive SARS-CoV-2 tests from 127,322 individual infections. Coronavirus case-outcome rates were evaluated by reference to 18,188,573 positive tests from 15,801,004 individual infections in the non-cancer population. From 2020 to 2022, the SARS-CoV-2 disease phenotype became less severe in both patients with cancer and the non-cancer population, though cancer patients remain at higher risk. In 2022, the relative risk of Coronavirus hospital admission, inpatient hospitalization, intensive care admission and mortality in cancer patients was 3.02x, 2.10x, 2.53x and 2.54x compared to the non-cancer population following multivariable adjustment, respectively. Higher risk of hospital admission and inpatient hospitalization were associated with receipt of B/T cell antibody and/or targeted therapy which also corresponded with an increased risk of Coronavirus mortality. Conclusion(s): The disease phenotype of SARS-CoV-2 in cancer patients in 2022 has evolved significantly from the disease phenotype in 2020. Direct effects of the virus in terms of SARS-CoV-2 hospitalization, intensive care and case fatality rates have fallen significantly over time. However, relative to the general population, people living with cancer and hematological malignancies remain at elevated risk. In order to mitigate the indirect effects of the SARS-CoV-2 pandemic in terms of disruption to cancer care, there should be increased focus on preventative measures. Used in conjunction with vaccination and early treatment programs, this will maximize quality of life for those with cancer during the ongoing pandemic and ensure the best cancer outcomes.

Productive Aging During COVID-19 - Lessons from WH SeniorLink

Introduction: According to the National Academies of Science, Medicine, and Engineering, even before the pandemic, 24% of Americans 65+ were considered socially isolated, and 43% of adults 60+ were lonely. Both experiences are associated with serious physical and mental health problems, including increased risks of dementia, stroke, depression, and suicidal ideation. As older adults engage in stricter social distancing to protect themselves from COVID-19, their risk of social isolation and loneliness is heightened. According to research by the Kaiser Family Foundation, 46% of adults 65+ reported that the worry and stress caused by pandemic has had a negative impact on their mental health. In order to combat this unique challenge, we must employ innovative, flexible solutions that adapt to the shifting circumstances and an uncertain future. Method(s): WH SeniorLink has developed an innovative program for integrating friendly visiting, mutual aid, needs assessment and case management, all delivered remotely by trained volunteers. The program was conceived, developed and executed since the beginning of COVID-19 restrictions and has grown to become a fully fledged 501(c)(3) organization, and is a model of flexible service delivery during this unusual time. The program operates through a volunteerism-mutual aid model. Volunteers are trained using online modules and quizzes and supervised by a licensed social worker, including training on needs and risk assessment. Volunteers are then matched with an older adult with similar interests and language preferences to provide friendly weekly phone calls, care packages and letters. Older adults with higher needs are referred to WH SeniorLink's service navigation program which operates using the online platform, Apricot, and is staffed by masters level social work interns and supervised by licensed social workers. Service navigation involves conducting comprehensive assessments and identifying resources and referrals. Older adults who express interest are also paired with each other to provide social support. Barriers to program development have included identifying consistent funding sources and volunteer attrition. Result(s): Data shows 169% growth in contacts made with older adults between May and October, with 2.5 times more older adults served in November than in May. Initial responses to the Dejong Gierveld Loneliness Scale and qualitative data collection reflect that older adults continue to feel lonely and isolated in the midst of the pandemic, but that WH SeniorLink is helping. By placing emphasis on empowering older adults to form sustained relationships with volunteers and their peers, WH SeniorLink encourages reciprocal relationships through which older adult participants are valued for their experiences and contributions. Conclusion(s): The mission of WH SeniorLink is to strengthen community ties and improve health outcomes among older New Yorkers by providing social-emotional support and connection to essential services. WH SeniorLink was founded during the COVID-19 pandemic, in response to the myriad of new challenges faced by older adults including greater risk of social isolation and increased disconnection from essential services. However, we recognize that the pandemic has only exacerbated a problem that began long before, and older adults are at risk of being left behind in the coming months and beyond. Funding(s): WH SeniorLink is funded by a starter grant from Columbia School of Social Work and subsequent crowdfunded donations.Copyright © 2021

The impact of the COVID-19 pandemic on clinical guidance, risk assessment and support for UK obstetric sonographers

UK obstetric sonographers adapted their working practices during the COVID-19 pandemic in response to new guidance issued by professional organisations, and requirements for on-going departmental risk assessments. This study aimed to provide an insight into the implementation of this guidance, completion of risk assessments and perception of support within UK obstetric ultrasound departments during the pandemic period. Obstetric sonographers working in the UK (n=138) used the Qualtrics XMTM platform to complete an anonymous, online, cross-sectional survey about their working experiences during the pandemic. Participants responded to closed questions about national guidance, risk assessments and their perception of support whilst providing fetal ultrasound screening services. Respondents provided additional detail about their experiences in these areas via free-text boxes. Over 90% of respondents were aware of, or had read guidance issued by professional organisations, although sonographers rated the overall usefulness of new guidelines at an average of 5.2/10 (where 0 = not useful at all, and 10 = extremely useful). Challenges for the implementation of guidance in departments were also identified, mostly related to the clinical working environment, including limitations of physical space (76.3%), time constraints (67.5%) and ventilation (61.3%). Most sonographers (77.2%) were aware that a departmental risk assessment had been undertaken, with waiting areas, scan rooms and clinically vulnerable staff highlighted as the most concerning factors. Sonographers felt most supported by their ultrasound colleagues (83.5%) and line managers (41.2%). They felt least supported by senior management and leadership personnel (60.8%), other antenatal colleagues (51.5%) and professional organisations (41.2%). Whilst most sonographers were aware of published COVID-19 guidance, challenges for its implementation in clinical departments were identified. Local risk mitigation strategies often did not prioritise the scan room environment, despite it being highlighted as a concern. Support from the wider, senior service team and professional organisations will be essential to facilitate post-pandemic recovery of the workforce.

Clinical and laboratory indicators in predicting the risk of chronic heart failure in COVID-19 survivors.

Coronavirus disease has many systemic disease symptoms and has severe consequences for the cardiovascular system. Objective. To assess the role of clinical and laboratory indicators in determining the risk of chronic heart failure (CHF) in COV-ID-19 survivors. Material and methods. In total, 151 patients treated in a monoinfectious hospital from 03.11.20 to 10.02.21 with a confirmed diagnosis of COVID-19 were retrospectively selected. Medical history and laboratory data were collected by reviewing electronic medical records. The data included age, gender, body mass index, smoking status, and comorbidities. The laboratory data included the results of hematology and blood chemistry, coagulation, and the levels of acute-phase proteins. The CHF occurrence was used as the study endpoint. Results and discussion. The study patients were divided into two groups depending on the presence of CHF: group 1 included 46 patients with CHF, and group 2 included 105 patients without CHF. The median age was 66.2 (50-92) years;91 (60.3%) were females. Laboratory tests, such as levels of the hs-C-reactive protein, lactate dehydrogenase, procalcitonin, creatinine, and bilirubin, were statistically significantly different in patients of the study groups, and the median values were higher in patients with CHF. Neutrophil-lymphocyte ratio (NLR) showed statistically significant differences between groups: in patients with CHF, the median was 4.97% compared to 3.62% (p=0.011) in those without CHF. The most significant predictors of an increased risk of CHF were age >=66 years (OR=8.038, p<0.001), procalcitonin level >=0.09 ng/mL (increased the CHF risk by 3.8 times, p<0.001), thrombocy-topenia <=220x109/L (p=0.010), an NLR ratio >=4.11% (p=0.010), and a history of chronic kidney disease (p=0.018). Conclusion. A model has been developed to determine the factors closely associated with the risk of chronic heart failure in CO-VID-19 survivors.Copyright © 2023, Media Sphera Publishing Group.

Comprehensive Code List Associated with CDC-Defined High-Risk Underlying Medical Conditions Leading to Potential Progression to Severe COVID-19 Outcomes

Objectives: This analysis was conducted to develop a comprehensive list of ICD-10 CM codes for underlying conditions identified by the CDC as being associated with high-risk of developing severe COVID-19 and assessed the consistency of these codes when applied to large US based datasets. Method(s): The comprehensive list of ICD 10-CM codes for CDC-defined high-risk underlying conditions were mapped from CDC references and FDA Sentinel code lists. These codes were subsequently applied to Optum's de-identified Clinformatics Data Mart Database (claims) and the Optum de-identified Electronic Health Record (EHR) database across 3 years (2018, 2019 and 2020) among continuously enrolled subjects >= 12 years of age to determine the performance and consistency in identifying these high-risk underlying conditions annually over these years. Result(s): A total of 10,276 ICD-10 codes were mapped to 21 underlying conditions. Within the claims data, 62.7% of subjects >= 12 years had >= 1 CDC-defined high-risk condition (excluding age) with 26.6% of patients >= 65 years while in the EHR data 38% had >= 1 high-risk underlying condition (excluding age) with 14.4% >= 65 years. These results were similar and consistent in both datasets across all years. Patients aged 12-64 years in the claims data had a higher rate of >=1 high risk underlying condition relative to the EHR data, 49.3% and 34%, respectively. The top 5 conditions among the >= 65 were identical across both databases: hypertension, immunocompromised status, heart conditions, diabetes (type 1 or 2), and overweight/obesity. The top 5 conditions among the 12-64 age group were also similar among the databases and included: immunocompromised status, hypertension, overweight/obesity, smoking (current or former), and mental health conditions. Conclusion(s): These findings present a comprehensive list of codes that can be used by researchers, clinicians and policy makers to identify and characterize patients that may be at high-risk for severe COVID-19 outcomes.Copyright © 2023

The Impact of the Sars-Cov-2 Pandemic (COVID-19) on the Incidence of Newly Diagnosed Multiple Myeloma Patients Using a Federated Network of Real-World Evidence in US and Germany

Objectives: COVID-19 had an impact on health care, including diagnostics. Early diagnosis of MM is a critical factor for prognosis. We examined the impact of COVID-19 on incidence of NDMM patients and on characteristics in NDMM patients in US and in Germany. Method(s): 44,164 NDMM patients were identified in TriNetX federated network across 55 healthcare organizations in US between January 2018 and December 2021. A bivariate analysis examined changes in patient characteristics in two cohorts before (Cohort 1;n=25513) and after (Cohort 2;n=18.651) the start of the COVID-19 pandemic in March 2020. 4172 NDMM patients were identified in the German database in a sample of across >100 healthcare organizations in the same time period. Similarly, bivariate analysis examined changes in patient characteristics before (Cohort 1;n=2252) and after (Cohort 2;n=1920) the start of pandemic. Result(s): Analysis of US data showed a significant decrease in incidence of NDMM. Bivariate analysis revealed that NDMM patients in Cohort 2 have a significantly higher risk profile compared with patients in Cohort 1, higher incidence of renal failure (13.5% v. 15.43%), heart failure (10.3% v 11.26%), bone lesions (12.6% v. 13.05%) and anemia (26.8% v. 29.75%). The German data indicated an increased risk profile in Cohort 2, with higher reporting of renal impairment (12.3% v. 15.5%) and cardiac impairment (8.3% v. 10.9%). The higher risk profile was reflected in a significant increase of all SLiM-CRAB criteria, notably hypercalcemia (24.1 % v. 36.9%), bone marrow plasma cell infiltration (28.1% v. 36.8%) and free light chain involvement (27.3% v. 41.3%). Conclusion(s): The results provide real-world evidence of a change in risk profile for patients with NDMM during COVID-19. This higher risk profile is observed in both the US and Germany, and may negatively impact outcomes such as progression-free and five-year overall survival.Copyright © 2023
