Assessing the impact of intensive positive feedback on staff morale, culture, civility and psychological safety in a South West maternity unit

Introduction: The importance of psychological safety, staff morale, culture and civility (PSMCC) has been highlighted by multiple recent maternity investigations as key to the provision of safe, high quality maternity care [1]. These factors are also crucial for staff retention and recruitment. Concomitantly, the NHS Staff Survey indicates an almost universal decline in staff motivation and engagement since COVID;a trend also noted in our institution [2]. Regular, authentic, individual and group positive feedback could improve PSMCC by creating a culture of kindness and appreciation, reinforcing positive behaviour and improving teamwork. At UHP, an established 'Learning for Excellence (LfE)' positive feedback system is in place, facilitating provision of volitional, authentic feedback to individuals and enabling organisational learning about what works. The aim of this project was to assess the impact of a shift to a more positive, appreciative narrative in maternity using intensive positive feedback from patients and staff. Method(s): A literature review to derive validated questions for incorporation into a questionnaire to assess baseline levels of PSMCC and perceptions of positive feedback receipt. QI methodology and stakeholder focus groups aided the development of the interventions. Once established, the impact of these positive interventions on PSCMM will be assessed. Result(s): There were 103 responses to the baseline questionnaire. 24% staff felt their actions at work were never positively acknowledged;45% felt undervalued. 63% felt they do not receive enough positive feedback, whilst 93% believed that receiving more positive feedback would improve staff morale, wellbeing, culture and care. Discussion(s): Based on these findings, interventions to provide regular, authentic, positive feedback across our maternity unit have been created. These include: 1)motivational board sharing positive feedback stories from patients and staff obtained via LfE, showcasing the kind, compassionate and high quality care delivered;2) Weekly email shots of LfE stories focussing on specific positive behaviours such as teamwork and patient centred care;3) A white board for staff and patients to share positive messages ad hoc;4)Promotion of the LfE initiative to patients thus increasing positive feedback to staff. The impact of these interventions will be assessed shortly and presented in full.Copyright © 2023 Elsevier Ltd

Fresh Versus Cryopreserved Allograft Outcomes in Peripheral Blood Stem Cell Transplantations

Background: The emergence of the COVID-19 pandemic saw an increased use of cryopreserved (cryo) peripheral blood (PB) grafts for allogeneic hematopoietic stem cell transplantation (HSCT). Outcomes of patients receiving either fresh or cryo grafts have yielded heterogeneous results. Herein, we retrospectively compared the outcomes of patients receiving fresh and cryo grafts at a single center.(Table Presented)Methods: Between 2019 and 2021, we reviewed data from 380 patients;167 (44%) received a fresh, and 213 (56%) received a cryo graft. Patients underwent myeloablative or nonmyeloablative HSCT from either matched or mismatched, related or unrelated donors. Cell doses were determined by number of donor cells collected and recipient weight at infusion. Engraftment, disease risk (DR) and acute GVHD were classified based on established criteria. Donor chimerism was collected at approximately day 28 and day 80 after HSCT. Unadjusted and adjusted estimates of overall survival (OS), relapse, and non-relapse mortality (NRM) as a function of time were obtained. The adjusted odds (grades III-IV acute GVHD) and the adjusted cause-specific hazard of failure (all other outcomes) were compared between the 2 groups. with the use of logistic (Figure Presented) or Cox regression, respectively. These models were adjusted for various factors known to be associated with each outcome. Result(s): The characteristics of patients between the 2 groups are shown in Table 1. There was a higher proportion of patients with high/very high DR in the fresh graft group (Table 1). Median time to neutrophil engraftment was 17 and 18 days in fresh vs. cryo, respectively. The adjusted hazard ratio (HR) of neutrophil engraftment (fresh vs. cryo) was 1.07 (95% CI, 0.86-1.34, p=0.54). Median time to platelet engraftment was 13 and 15 days, respectively, and the adjusted HR of platelet engraftment was 1.32 (1.06-1.65, p=0.01). Day 28 chimerism data were available for 272 patients (113 fresh and 159 cryo). At day 28, donor CD3 chimerism was below 50% in 5 out of 113 (4.4%) and 17 out of 159 (10.7%) patients receiving fresh and cryo grafts, respectively (p= 0.06). At day 80, 3 out of 121 (2.5%) patients in the fresh group and 4 out of 165 (2.4%) in the cryo group had CD3 chimerism below 50%. The adjusted HRs (fresh vs. cryo) for death and NRM were 0.83 (0.54-1.28, p=0.40) and 0.71 (0.38-1.33, p=0.29), respectively (Figures 1 and 2). The adjusted HR for relapse was 0.65 (0.42-0.99, p=0.05) (Figure 3). The adjusted odds ratio (fresh vs. cryo) for grades III-IV GVHD was 1.65 (0.94-2.9, p=0.07). Conclusion(s): In this single-center retrospective study we observed numerically better outcomes with fresh grafts relative to cryo grafts for all examined endpoints with the exception of grades III-IV aGVHD, although none of the differences were definitive with the possible exception of relapse and platelet engraftment. Further studies are needed to confirm our observations.Copyright © 2023 American Society for Transplantation and Cellular Therapy

Racial and Ethnic Disparities in the Use of Live Video Telemedicine

Purpose of Study As a result of the coronavirus disease 2019 (COVID-19) pandemic and physical distancing, telehealth has been scaled up as a key strategy to address the need for virtual access to medical services. Previous studies have examined use of web-portals for accessing health information, but data on the use of live video telemedicine for disease management across different ethnicities is limited. The objective of this study is to determine if disparities exist among different ethnic groups in accessing live video telemedicine services. Methods Used A literature review was conducted using databases such as PubMed and Google Scholar. Key search terms included: telehealth, telemedicine, ethnicity, and disparities. Studies were included if a) they were conducted in the United States, b) patients used a live video telehealth service with a provider, c) focused on telemedicine use across different racial and ethnic groups, and d) investigated completed access to live video telemedicine at the individual level, and not potential access at the aggregate level. Summary of Results Of 25 articles found, 5 met our inclusion criteria. Overall, white patients had higher rates of telehealth visit completion and video telehealth use than non-white patients. Studies that used telehealth visits for diabetes education and glycemic control showed that self-care improved in all ethnic groups, but despite tailored intervention, minority groups never achieved the same level of self-care as whites. Conclusions Our review suggests that overall white patients have better access to live video telemedicine, and use the services at higher rates compared to non-white patients. However, since this trend was not seen in every study, it is likely that other factors beyond race and ethnicity play a role in access to telemedicine. Effective strategies are needed to mitigate disparities to ensure equitable telemedicine access.

Digital Transformation for Promoting Renewable Energy & Sustainability: A Systematic Approach for Carbon Footprint Reduction in Well Construction

As the industry recovers from the recent downturn in petroleum commodity prices and the economic impacts from coronavirus (COVID-19), governing authorities in most countries are imposing methodological measures to promote the reduction of carbon footprint. This affects every industry including the petroleum sector. Therefore, most investors and stakeholders have increased their focus on Environmental, Social, and Corporate Governance (ESG) policies. During the well construction phase, a transition from a hydraulic to an electric tong is achieved, resulting in carbon footprint reduction. Achieving carbon neutrality or carbon emission reduction while producing hydrocarbons is one of the topmost key performance indicators (KPIs) in the industry. With the implementation of digital technologies in the tubular and casing connection make-up process, a hydraulic tong is substituted with an electric tong of an equivalent specification. The energy consumption for both systems are calculated and compared. Other important KPIs on tracking operational cost are also assessed and the results are then compared to determine the benefits of implementing the upgraded digitalized tong solution. The electric tong digitalized solution, commercially available in the petroleum industry, is a key enabler for carbon emission reduction while running tubulars in/out of the wellbore. This solution is one of the milestones that serve as foundation to advocate carbon reduction. Eventually, this will lead to establishing carbon neutrality during hydrocarbon extraction and production. The results concluded that a digitalized solution eventually reduced personnel on board working in the "red zone," which eventually leads to carbon emission reductions caused by a decrease in fuel consumption. The decrease of 43% in CO2 emission is observed while performing tubular connection process. Moreover, an overall comparison between a legacy system with the digitalized electric system displayed more than 59% reduction in CO2 during the tubular running services. In addition to carbon reduction, this electric power and control solution allows for more precise torque control, leading to enhanced system integrity and increased reliability achieved by cleaner energy. With this digital solution, not only is the safety and well-being of rig personnel enhanced to avoid any recordable incidents, the reduction of carbon emission is also achieved, aligning to the objectives of current ESG regulatory authorities. This paper will provide comprehensive details on the novelty of this technology and solution offered to the industry. © 2022, Offshore Technology Conference. All rights reserved.

Understanding higher education students' sense of belonging: a qualitative meta-ethnographic analysis

The current literature on ‘sense of belonging' spans a number of disciplines, with no apparent consensus on definition between these, complicated by the fact that sense of belonging is temporal and context-sensitive (such as during COVID-19). In particular, a closer look at how students define sense of belonging is needed from an up-to-date perspective to help them feel more connected to the faculty/campus and improve their wellbeing and mental health in the ‘new normal' and ‘next normal' post-pandemic eras. Therefore, this study explores higher education students' sense of belonging, a concept that has not been adequately conceptualised, from their perspectives. As these perspectives are subjective, an interpretive approach is required to generate rich meanings. This study has adopted a meta-ethnographic approach to synthesise qualitative studies, which allows for comparison and synthesis of studies into a new interpretation through translations. Interpretive qualitative synthesis resulted in one higher-order concept, four main concepts, and nineteen sub-concepts that conceptualise higher education students' understanding of sense of belonging to their universities. © 2023 The Author(s).

Parent and guardian social media use in a district general hospital paediatric dermatology outpatient clinic

In the age of 'influencers', social media is exerting an ever-increasing impact in dermatology. More than half the world's population use social media and its popularity continues to grow. However, studies have confirmed that content is not always evidence based. Owing to its accessibility, social media is frequently used as an information resource for patients on managing their own skin condition. The influence that it has on parents and guardians in paediatric dermatology is less well described. A 10-point questionnaire was designed to assess social media use in parents and guardians with regard to their child's skin condition. Data were collected on parent or guardian age, sex, online platforms used and changes in management as a direct result of social media-sourced information. Children's demographics, diagnosis and disease duration were also noted. Questionnaires were anonymously distributed in a general paediatric dermatology outpatient clinic waiting room over 3 months. A chi2-test of independence was used to examine the relationship between social media use and parent or guardian age, sex and child's disease duration. In total, 116 parents and guardians participated in the survey. Average child age was 9.9 years (range 0-18), male-to-female ratio 1 : 1. Diagnoses included eczema (n = 35;30%), naevi or other skin lesions (n = 27;23%), acne (n = 18;15%) and psoriasis (n = 4;3%). Ninety-three (80%) of the dermatoses had a duration of > 1 year. Over 40% (n = 48) of parents and guardians used social media on at least one occasion as an educational resource for their child's skin condition across eight online platforms, most commonly Facebook (n = 21;44%), Google (n = 15;31%) and YouTube (n = 8;16%). There was no significant relationship between social media use and parent or guardian age (P = 0.89), sex (P = 0.10) or disease duration (P = 0.77). Of the 48 social media users, 26 (54%) parents and guardians changed their use of over-the-counter products, and a further 14 (29%) altered use of physician-prescribed treatments as a result of social media-derived information. Our findings suggest that a significant number of parents and guardians use social media to understand their child's dermatosis and some change the management based on it. Following the COVID-19 pandemic, a shift to virtual platforms for human interactions has fuelled the use of social media. With its growing popularity, it is likely that dermatologicalrelated content will also increase and therefore this should be addressed in both adult and paediatric clinics.

Longitudinal lung function assessment of patients hospitalised with COVID-19 using 1H and 129Xe lung MRI

Introduction: The progression of pathophysiological pulmonary changes in patients following acute COVID-19 is not well established. Method(s): Patients hospitalised with COVID-19 pneumonia without signs of ILD, had MRI exams at a median of 6 (n=9), 12 (n=9), 25 (n=7), and 52 (n=3) weeks. MRI sequences included: dynamic contrast enhanced (DCE) lung perfusion,129 Xe diffusion weighted (DW-MRI), 129Xe ventilation and 129Xe 3D dissolved phase imaging. Result(s): 9 patients (age 56+/-9 years;7 male;1 required treatment in an ICU) were recruited. Median RBC:TP was abnormally low at all visits compared to reference age and sex matched data. An individual's RBC:TP was significantly and positively associated with an increase in their pulmonary blood volume (p=0.026). For patients with 52 week data available, one showed a continued increase in RBC:TP, 2 patients maintained a low RBC:TP (Figure 1). Ventilation defect percentage, and ventilation heterogeneity significantly decreased at 25 weeks compared to 6 129 129 129 weeks (p=0.010 and p=0.048). DW-MRI was normal at all visits. Dissolved phase xenon imaging showed RBC:TP significantly increased at 12 and 25 weeks compared to 6 weeks (p=0.048). Conclusion(s): In patients recovering after COVID-19, poor gas transfer is reflected by impaired xenon transfer, which improves alongside pulmonary blood volume.

Side Effects of the mRNA COVID-19 Vaccines in Women Treated for Breast Cancer

Background: The introduction of the novel COVID-19 vaccination raised concerns regarding side effects from patients who had undergone breast cancer treatment. Lymph node swelling after the mRNA vaccines (Moderna, Pfizer) is a distressing side effect for women treated for breast cancer as it may indicate cancer progression or recurrence. Patients at risk of breast cancer-related lymphedema (BCRL) are fearful that lymph node swelling from the vaccine could incite or worsen BCRL. Data investigating associated side effects in this population is essential for patient education and future self-advocacy. Purpose(s): The purpose of this study was to elicit side effects associated with the COVID vaccine in women treated for breast cancer. Method(s): 4,945 surveys were sent to women over the age of 18 who had received breast cancer treatment and had been prospectively screened for BCRL with perometry. 621 participants who received an mRNA vaccine and responded to the survey were included in analysis, 469 of whom completed booster dose surveys. Participants were asked about type and duration of side effects after each vaccine dose. Solicited side effects included injection site soreness, swelling, or redness;swelling, numbness, or heaviness of the arm;generalized muscle soreness (GMS);fatigue;headache;joint pain;chills;nausea;vomiting;fever;Bell's palsy;axillary or supraclavicular lymph node swelling;other;or none of the above. We computed frequencies and the median duration of side effects for each dose. To investigate predictors of side effects, we fit multivariable logistic regression models separately for each side effect, with random effects for participants to account for clustered responses. We considered significant predictors those with p < 0.05. Result(s): Of the 621 participants, the median follow-up time between breast surgery and date of first vaccine dose was 69 months. The distribution of the top 5 side effects is presented in Table 1. Of note, the majority of participants who reported lymph node swelling (9.8% dose 1, 12.9% dose 2, 11.3% dose 3) reported it in the axilla ipsilateral to the vaccine (54.1% D1, 61.3% D2, 71.7% D3). Lymph node swelling was also reported in the axilla contralateral to the vaccine (45.9% D1, 45% D2, 24.5% D3), supraclavicular region ipsilateral (29.5% D1, 26.3% D2, 32.1% D3) and contralateral (18% D1, 18.8% D2, 9.4% D3) to the vaccine. Older patients reported each side effect significantly less frequently. Those who had received neoadjuvant chemotherapy reported significantly more GMS and headache than those who did not. Those who had received regional lymph node radiation were less likely to report GMS, as were patients who had sentinel lymph node biopsies (vs. no lymph node surgery). The median duration of side effects for all three doses was 48 hours or less, with the plurality (41.0% D1, 38.7% D2, 44.1% D3) of participants reporting side effects lasting 24 hours or less. While all side effects apart from injection site soreness were significantly more common in the second than the first doses, the duration of side effects only increased for 28.1% of participants. Conclusion(s): Over 86% of women treated for breast cancer may experience at least one side effect after any dose of the COVID-19 vaccine. This data, collected specifically for patients with breast cancer, will help enhance guidelines for structured and universal education regarding additional doses of the vaccine in the future. This will allow patients to better understand COVID vaccine side effect profiles after breast cancer treatment and self-advocate prior to future doses. (Table Presented).

17-year trends of body mass index, overweight, and obesity among adolescents from 2005 to 2021, including the COVID-19 pandemic: a Korean national representative study.

OBJECTIVE: There is a lack of pediatric studies that have analyzed trends in mean body mass index (BMI) and the prevalence of obesity and overweight over a period that includes the mid-stage of the COVID-19 pandemic. Thus, we aimed to investigate trends in BMI, overweight, and obesity among Korean adolescents from 2005 to 2021, including the COVID-19 pandemic. SUBJECTS AND METHODS: We used data from the Korea Youth Risk Behavior Web-based Survey (KYRBS), which is nationally representative of South Korea. The study included middle- and high-school students between the ages of 12 and 18. We examined trends in mean BMI and prevalence of obesity and/or overweight during the COVID-19 pandemic and compared these to those of pre-pandemic trends in each subgroup by gender, grade, and residential region. RESULTS: Data from 1,111,300 adolescents (mean age: 15.04 years) were analyzed. The estimated weighted mean BMI was 20.48 kg/m2 (95% CI, 20.46-20.51) between 2005 and 2007, and this was 21.61 kg/m2 (95% CI, 21.54-21.68) in 2021. The prevalence of overweight and obesity was 13.1% (95% CI, 12.9-13.3%) between 2005 and 2007 and 23.4% (95% CI, 22.8-24.0%) in 2021. The mean BMI and prevalence of obesity and overweight have gradually increased over the past 17 years; however, the extent of change in mean BMI and in the prevalence of obesity and overweight during the pandemic was distinctly less than before. The 17-year trends in the mean BMI, obesity, and overweight exhibited a considerable rise from 2005 to 2021; however, the slope during the COVID-19 pandemic (2020-2021) was significantly less prominent than in the pre-pandemic (2005-2019). CONCLUSIONS: These findings enable us to comprehend long-term trends in the mean BMI of Korean adolescents and further emphasize the need for practical prevention measures against youth obesity and overweight.

Cerebral venous thrombosis after ChAdOx1 nCoV-19 vaccination: a systematic review

OBJECTIVE: To perform a systematic review of case reports or case series regarding thrombosis with thrombocytopenia syndrome (TTS) and cerebral venous thrombosis (CVT) related to ChAdOx1 nCoV-19 vaccination to address the clinical features, laboratory findings, treatment modalities, and prognosis related with CVT. SUBJECTS AND METHODS: We included 64 TTS patients from 19 articles, 6 case series and 13 case reports, in which thrombosis occurred after the first dose of ChAdOx1 nCoV-19 vaccination published up to 30 June 2021 in Embase, ePubs, Medline/PubMed, Scopus, and Web of Science databases. RESULTS: Of the 64 TTS patients, 38 (59.3%) had CVT. Patients with CVT were younger (median 36.5 vs. 52.5 years, p<0.001), had lower fibrinogen levels (130 vs. 245 mg/dL, p=0.008), had more frequent history of intracerebral hemorrhage (ICH), and had higher mortality rate (48.6% vs. 19.2%, p=0.020) than that of patients without CVT. In multivariable analysis, the possibility of presence of CVT was higher in younger age groups [odd ratio (OR): 0.91, 95% confidence interval (CI): (0.86-0.97, p<0.001)] and those with accompanying intracerebral hemorrhage (ICH) (OR: 13.60, 95% CI (1.28-144.12, p=0.045). CONCLUSIONS: Our study demonstrated that CVT related to ChAdOx1 nCoV-19 vaccination was associated with younger age, low levels of fibrinogen, presence of ICH and more frequent mortality compared to those of non-CVT. If TTS occurs after ChAdOx1 nCoV-19 vaccination, the presence of CVT in patients with young age or ICH should be considered.

Longitudinal 129xe and 1h Lung Mri Assessment of Lung Structure, Ventilation, Perfusion, and Gas Transfer Following Hospitalization with Covid-19

The long-term effects of coronavirus disease 2019 (COVID- 19) pneumonia on the lungs and pulmonary circulation require further characterization. We assessed progression of pathophysiological pulmonary changes during 1 year of follow-up of patients who had been hospitalized because of COVID-19. After discharge, recruited patients had up to four MRI examinations at a median of 6 (n=9), 12 (n=9), 25 (n=7) and 52 (n=3) weeks. Lung MRI examinations included: ultra-short echo time (UTE), dynamic contrastenhanced (DCE) lung perfusion, 129Xe diffusion weighted (DW-MRI), 129Xe ventilation and 129Xe 3D dissolved phase imaging. Nine patients (age 56 +/-9 years;six male) were recruited. Ventilation defect percentage and whole lung coefficient of variation of lung ventilation decreased significantly at 25 weeks (visit 3) compared with visit 1 at 6 weeks (p=0.010 and p=0.048). The UTE imaging indicated no evidence of lung scarring, and DW-MRI indicated normal lung microstructure across all visits. Dissolved phase xenon imaging showed that RBC:TP increased significantly at visits 2 and 3 compared with visit 1 (p=0.048). Median RBC:TP was abnormally low at all visits compared with reference age- and sex-matched data. An individual's RBC:TP was associated significantly and positively with an increase in their pulmonary blood volume (p=0.026). For patients with 52-week data available, one showed a continued improvement in RBC:TP;however, two of the patients maintained a low RBC:TP. In patients recovering from COVID-19, xenon gas transfer improves alongside pulmonary blood volume. Further work is needed to establish the proportion of post-COVID-19 patients who have longer-term impairment in xenon transfer and to correlate changes in lung MRI parameters with symptoms, lung function tests and other imaging modalities. Persistent impairment of xenon transfer might represent a physiological mechanism underlying ongoing symptoms in some patients and might indicate damage to the pulmonary microcirculation.

Healthcare Personnel Interactive Pathogen Exposure Response System

Background. Infectious disease exposure investigations in the hospital are labor-intensive for the infection prevention and control (IPC) team and vulnerable to healthcare personnel (HCP) recall bias. We developed an electronic health record (EHR) algorithm to identify and rank patient-HCP interactions based on the likelihood and intensity of exposure. Methods. We compared conventional and EHR-based findings from seven exposure investigations conducted between November 1, 2020 and February 1, 2022 at The Johns Hopkins Hospital (JHH), a 1095 bed academic tertiary center in Baltimore, MD. Conventional exposure investigations were conducted for hospitalized patients who tested positive for SARS-CoV-2 while not in COVID-19 isolation precautions. IPC contacted department managers to identify and report potentially exposed HCPs to occupational health. The EHR-based method identified HCP-patient interactions based on clinical data such as documentation in the flowsheet, medication administration, etc. A score was calculated for each HCP based on the estimated duration and intensity of the contact. Genomic sequencing of available samples was performed to investigate transmission events. Results. Overall, the EHR-based system identified 75% (59/79) of the HCPs identified by conventional exposure investigations and 100% of those who document in the EHR. In contrast, it was unable to identify any potentially exposed individuals who do not document in the EHR (Table 1). All patient-HCP COVID-19 transmissions identified by conventional investigation and confirmed through genomic sequencing were identified by the EHR-based system, and all had high-intensity scores (i.e., top quartile of the list of exposed individuals). Conclusion. We found clinical EHR data was highly sensitive and specific in identifying potentially exposed HCPs compared with conventional exposure investigations. The inability to detect interactions with support staff or others who do not document in the EHR was a limitation and suggests that EHR data can augment but not replace conventional exposure investigations. The system's speed, ease, and lower resource requirements make it a promising tool to more efficiently complete exposure investigations in healthcare settings.

Cerebral venous thrombosis after ChAdOx1 nCoV-19 vaccination: a systematic review.

OBJECTIVE: To perform a systematic review of case reports or case series regarding thrombosis with thrombocytopenia syndrome (TTS) and cerebral venous thrombosis (CVT) related to ChAdOx1 nCoV-19 vaccination to address the clinical features, laboratory findings, treatment modalities, and prognosis related with CVT. SUBJECTS AND METHODS: We included 64 TTS patients from 19 articles, 6 case series and 13 case reports, in which thrombosis occurred after the first dose of ChAdOx1 nCoV-19 vaccination published up to 30 June 2021 in Embase, ePubs, Medline/PubMed, Scopus, and Web of Science databases.

Patients with CVT were younger (median 36.5 vs. 52.5 years, p<0.001), had lower fibrinogen levels (130 vs. 245 mg/dL, p=0.008), had more frequent history of intracerebral hemorrhage (ICH), and had higher mortality rate (48.6% vs. 19.2%, p=0.020) than that of patients without CVT. In multivariable analysis, the possibility of presence of CVT was higher in younger age groups [odd ratio (OR): 0.91, 95% confidence interval (CI): (0.86-0.97, p<0.001)] and those with accompanying intracerebral hemorrhage (ICH) (OR: 13.60, 95% CI (1.28-144.12, p=0.045). CONCLUSIONS: Our study demonstrated that CVT related to ChAdOx1 nCoV-19 vaccination was associated with younger age, low levels of fibrinogen, presence of ICH and more frequent mortality compared to those of non-CVT. If TTS occurs after ChAdOx1 nCoV-19 vaccination, the presence of CVT in patients with young age or ICH should be considered.

PROMOTION OF PHYSICAL ACTIVITY THROUGH HEALTH APPLICATIONS AMONG STUDENTS OF SELECTED UNIVERSITIES – A PRELIMINARY STUDY

Mobile health applications provide individuals with a mobile tool that can be tailored to meet various health needs and physical activity goals, which is particularly important during the COVID-19 pandemic and the associated social distancing protocols. The consequence that the pandemic has on the mental health of university students has prompted and increased the demand of physical activity interventions. The aim of this study was to determine the self-perceived effects of mobile health applications on physical activity participation among university students. Participants included students registered in one of the faculties at a university in Johannesburg. Data collection took place by means of an electronic questionnaire using Google Forms as a platform, completed by a sample of 192 students. The findings in the study reflected that majority of university students use health applications to increase physical activity levels or to track current activity levels. Participants also indicated that specific health applications were used to set goals, monitor progress and receive feedback. Aerobic activities proved to be the more popular type of physical activity in comparison to anaerobic activity. This study concluded that health applications can be used as a tool to facilitate and promote physical activity participation in the university student population. © 2022 The authors.

Real World Experience Utilizing Donor Kidneys at Risk for Acute Kidney Injury with Belatacept Based Maintenance Immunosuppression

Purpose: The demand for kidney transplant continues to rise, and limited supply has encouraged acceptance of marginal donor organs, such as those at risk for acute kidney injury (AKI). We evaluated the utilization of such organs (defined as donation after cardiac death, pediatric donors, kidneys with a cold ischemic time >24 hrs, terminal serum creatinine (SCr) >2mg/dL or rising SCr with decreasing urine output at donation) at our center who were discharged on belatacept based maintenance immunosuppression with mycophenolate and steroids (BBMS). Method(s): This retrospective, descriptive study examined kidney transplant recipients (KTR) who received AKI organs and were discharged on BBMS between 1/2019-4/2021. Primary outcome assessed graft function and rejection at 6 & 12 months (mos) post-transplant (txp). Secondary outcomes evaluated graft failure, mortality, infection, DSA & changes to BBMS. All outcomes were evaluated at 1yr if records were available. Result(s): 68 KTR w/1 yr results & 52 w/6 mo results on BBMS were included. Baseline characteristics (Table 1) show most KTR received a DCD or en bloc organ and lymphocyte depleting induction. Mean eGFR improved from 1 to 6 mo post-txp and was stable through 1yr. Episodes of biopsy proven rejection were more common during the first 6mos post-txp. There were 2 deaths during the study period, due to COVID, and no graft failures. Twelve KTR developed DSA. There were 21 KTR with CMV viremia, mostly in moderate risk group, & 12 with BK viremia. Table 4 shows changes to BBMS occurred in 32 KTR. Most KTR required multiple BBMS changes with most common dose adjustments to mycophenolate due to leukopenia or neutropenia. Conclusion(s): Utilization of AKI organs with BBMS in KTR at our center resulted in no graft failures & sustained eGFR despite more rejection episodes during the first 6mos post-txp. Although 32 KTR had changes to BBMS, only 5 KTR had rejection following a change. Incidence of CMV was common but did not impact KTR outcomes. Overall, BBMS could be a promising option in AKI organs to avoid nephrotoxicity associated with CNI based regimens. These findings suggest the need to further evaluate the impact of long-term outcomes associated with changes made to BBMS in AKI donor organs.

The Evolution of Mortality in Kidney Transplant Recipients at a Single Center in the Era of Covid

Purpose: Mortality secondary to COVID-19 infection is significantly higher in solid organ transplant recipients compared to the general population. Limited data exists evaluating the impact COVID has had on mortality compared to other causes, with even less data specific to the Mountain West region of the United States. This quality improvement project seeks to evaluate trends in patient mortality at a center in the Mountain West region before and after the COVID pandemic in kidney transplant recipients (KTR). Method(s): This is a retrospective single-center analysis of all adult KTRs who underwent transplant between January 1999 and July 2021 and subsequently died between January 2015 and July 2021, assessing the change in mortality trends with the advent of the COVID-19 pandemic. Additional endpoints include time from transplant to death, graft status at time of death, and COVID vaccination status. Data collection included UNOS data reports as well as manual electronic medical record review. Result(s): One-hundred and seventy-two KTRs were included with baseline characteristics described in Table 1. Prior to the COVID-19 pandemic, the most common etiology of mortality was cardiovascular cause with a median of 18% mortality (see Table 1). Of those who died in 2020, 33% were secondary to COVID-19 leading to a 174% increase in cumulative patient deaths compared to the year prior (23 vs 40 patient deaths in 2019 vs 2020;see Table 1 and Figure 1). Of those who died secondary to COVID, none had received the COVID-19 vaccine. Conclusion(s): COVID-19 pneumonia and its associated complications have led to an increase in and earlier mortality prior to vaccination implementation, changing the mortality landscape in KTRs. Further investigation is needed to elucidate non- COVID related changes in mortality and patient outcomes in the ongoing COVID pandemic.

HEMOLYTIC ANEMIA EXACERBATION IN CHRONIC PAROXYSMAL NOCTURNAL HEMOGLOBINURIA AFTER COVID-19 VACCINATION

SESSION TITLE: Issues After COVID-19 Vaccination Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disorder that can lead to thrombosis, hemolytic anemia and leukemia. Though there are documented relationships between autoimmune hemolytic anemia (AIHA) and COVID-19 infection, this is the first to highlight aa potential association between PNH exacerbations and COVID vaccinations. CASE PRESENTATION: A 38 year-old female with a history of chronic paroxysmal nocturnal hemoglobinuria (PNH) currently on maintenance ravculizumab therapy presented with 3 days of generalized fatigue, chills, and worsening scleral icterus. She reports being unable to move out of the bed with concomitant somnolence. Of note, she received her second dose of the Moderna COVID-19 vaccine 2 days prior to symptom onset and not had any similar symptoms prior to this episode. Patient was hemodynamically stable on admission and afebrile. Physical exam revealed generalized lethargy/weakness and jaundice. Chest x-ray did not demonstrate any evidence of infection or pleural effusions. Initial complete blood count showed a hemoglobin of 5.9 g/dL, compared to her baseline of 9 without any evidence of bleeding. Absolute reticulocyte and bilirubin levels were elevated to 295.2 x 109 and 4.7 mg/dL respectively with a haptoglobin of <20 mg/dL. She received a total of 3 units of packed red-blood cells with subsequent stable hemoglobin levels and did not require emergent use of glucocorticoids or plasma exchange. Her lethargy improved slowly, and within a week, she returned back to her baseline functional status. She was ultimately stable and discharged for follow up with her hematologist without any complications. DISCUSSION: Though the sequelae of COVID-19 infections and associated hematologic diseases have been extensively established, the pathogenesis of COVID-19 vaccinations associated exacerbations remain unclear. Given the timing of the onset of our patient's symptoms, it is highly suggestive that her second COVID-19 vaccination was the inciting factor for her acute hemolytic anemia. It is crucial to be cognizant of the potential hematologic side effects in individuals with rare auto-immune disorders such as PNH and take into consideration the timing of vaccination or booster administrations. CONCLUSIONS: While COVID-19 vaccination benefit most likely outweighs the risks for this specific patient population, our case raises the question about the need for extra precautions in patients with known PNH associated AIHA including the timing of PNH treatment before receiving the vaccination.
