ABSTRACT

Aims The study aimed to examine the nature and outcomes of social support for the well-being and quality of life (QoL) of adults with epilepsy. Methods The Australian Epilepsy Longitudinal Survey's 5 th Wave included the Medical Outcomes Study Modified Social Support Survey on four dimensions of social support and the QOLIE-31. Both numerical data and open-ended responses were analyzed quantitatively and qualitatively. A mixed method was used where quantitative analysis used t -tests, analysis of variance and block recursive regression, and qualitative analysis identified themes. Results Three-hundred thirty-two people with epilepsy (PWE) participated. The quantitative component showed that for emotional/informational support being older and living alone were key factors. These as well as household income were important in tangible support. For affectionate support living alone and household income were factors, but only income was a factor for positive social interaction. In addition, only positive social interaction predicted increased QoL. In the qualitative component of the study both positive and negative supports were identified for the emotional/informational supports. Many reported the benefits of having information, although some reported failure to have their needs taken seriously by health professionals or epilepsy associations. Inability to drive was an important feature of negative tangible support as was finding some assistive services unaffordable. Reports of positive social interaction identified being accepted as a person with epilepsy that is the primary concern. Peer support plays a role here. Discussion The findings of factors affecting the four dimensions of support in this study have supported a number of studies. This includes the effects of positive social interaction on QoL. The qualitative analysis supports these results, but it also contributes to deeper understanding of support in the lives of PWE. Conclusion Social support is a particularly important issue for PWE. The results of this study demonstrate the complexities and benefits of obtaining the appropriate forms of support. This survey took place before the coronavirus disease 2019 pandemic and it may well be that this phenomenon affects PWE's support needs. Copyright © 2023. Indian Epilepsy Society.

ABSTRACT

Introduction: Minimal change disease (MCD) accounts for approximately 15% of adults with idiopathic nephrotic syndrome (NS). We report the case of minimal change disease in a patient who presented with signs and symptoms of NS following Covid-19 immunisation vaccine. Method(s): Case: A 58-year-old male with negligible past medical history developed generalised swelling 2 days following receiving the Pfizer Covid-19 booster. On examination, he had a blood pressure of 130/80 and anasarca. Relevant laboratory results include a creatinine of 123, estimated glomerular filtration rate (eGFR) of 55, albumin of 9, urine protein: creatinine ratio of 713, and hyaline casts of moderate quantity. A kidney biopsy revealed glomerular sclerosis appropriate for age, and normal vessels and tubules. Immunofluorescence showed negative serology. A diagnosis of minimal change disease was made. The patient was treated with high dose prednisone at 1mg/kg/day and went into remission. The patient was followed up 2 months after admission, and investigations revealed a creatinine of 70, eGFR of >90, albumin of 34 and urine protein:creatine ratio of 58. Result(s): / Conclusion(s): Discussion and conclusion: This is the first case of Covid-19 vaccination induced NS reported in New Zealand. Theorised mechanism of injury includes T-cell mediated immune dysregulation, leading to glomerular disease (Sahin et al., 2020). Different glomerular diseases have been reported to occur for the first time following the Covid-19 vaccination (Klomjit et al., 2021). There has also been reports of reactivation of disease following Covid-19 immunisation (Hartley et al., 2022 and Leong et al., 2021). mRNA vaccination induced NS should be considered in all patients presenting with apparent idiopathic NS. This is especially important as we continue to learn more about the Covid-19 vaccination. No conflict of interestCopyright © 2023

ABSTRACT

Introduction: The COVID-19 pandemic has necessitated the rapid transition of many face-to-face health services to alternate modes of service delivery. The objective of this study was to explore the benefits, challenges and perceived quality of a telehealth service delivery model from the perspective of clients and students. Further, students' perceptions relating to the quality of the educational experience were also explored. Methods: The study was set in a student-led interprofessional health and wellness clinic in rural Queensland, Australia. A qualitative case study design was used, including semistructured student interviews and client open-response survey data. Participants were nursing and allied health students who completed a student-led interprofessional clinic placement and adults with low to rising risk of chronic disease who attended the clinic for telehealth delivered services. Results: Themes identified following analysis included: new or adapted skills needed for success;challenges, limitations and the need for resources, training and support;quality interprofessional education experiences can be achieved in telehealth;coming away with a new set of skills;the important role of the client for success;and benefits and disadvantages of telehealth for clients. Conclusions: The findings support that telehealth-based service-learning models are a feasible way to deliver health and wellness services from the perspective of students and clients and provide students with important skills for rural health service delivery.

ABSTRACT

SESSION TITLE: COVID-19 Co-Infections SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 1:45 pm INTRODUCTION: The COVID-19 pandemic has highlighted the emergence of multidrug-resistant bacterial pathogens. Here we present a case of the successful treatment of a COVID-19 superinfection with Citrobacter freundii, which produced both a Klebsiella pneumoniae carbapenemase (KPC) as well as a New Delhi Metallo-Beta-Lactamase (NDM-1). CASE PRESENTATION: A 53-year-old male without significant past medical history was admitted to the intensive care unit for acute hypoxemic respiratory failure due to COVID-19 pneumonia. His hospital course was complicated by progressive hypoxia requiring intubation and mechanical ventilation. Due to persistent fevers and increased respiratory secretions, he was placed on empiric antibiotic therapy including vancomycin, cefepime, and briefly meropenem. Blood cultures were periodically drawn and ultimately demonstrated no growth. However, a respiratory culture via bronchoalveolar lavage was positive for multidrug-resistant Citrobacter freundii. Susceptibilities showed high level of resistance to meropenem, Imipenem, Ceftazidime-Avibactam as well as Aztreonam. Molecular testing confirmed the presence of both KPC and NDM-1 β-lactamases. The patient was treated with a combination of Aztreonam 2g plus Ceftazidime-Avibactam 2.5g IV every eight hours via simultaneous infusion for fourteen days, resulting in clinical improvement and discharge to a rehabilitation facility. DISCUSSION: The emergence of carbapenem-resistant enterobacteria has been identified as a major clinical problem. The high rates and high mortality of carbapenem-resistant enterobacteria complicating the course of COVID patients during the pandemic highlighted the importance of this issue. Among the Enterobacteriaceae, β-lactam resistance is primarily caused by enzymatic degradation by β-lactamases. Two carbapenemase subclasses are especially problematic: KPC and NDM-1. Horizontal gene transfer and clonal expansion have enabled KPC and NDM-1 to spread worldwide. However, coexistence of these two resistant mechanisms within the same pathogen has rarely been reported. Recently, high stability, non-inferior fitness, and transferability among patients of KPC-2-NDM-1-CRKPs have been documented, raising further concerns about the risk for further spread and increasing rates [1]. Therapeutic options are limited. We used a combination of Ceftazidime/Avibactam plus Aztreonam for treatment, based on limited in vitro studies demonstrating a synergistic effect and superior clearance rather than either antibiotic alone or administered in sequence [2,3]. CONCLUSIONS: Superinfections with carbapenem-resistant enterobacteria have increased in the context of the COVID-19 pandemic and are likely to become more prevalent in our hospitals. Prompt recognition and appropriate therapeutic selection are paramount for treating these highly resistant organisms. Reference #1: Gao H, Liu Y, Wang R, Wang Q, Jin L, Wang H.

ABSTRACT

BACKGROUND: COVID-19 continues to be an ongoing problem worldwide, especially for those who are disproportionately affected due to their social determinants of health, as they are often at a socioeconomic disadvantage. We are primarily interested in evaluating how education level, income, race, ethnicity, and obesity are correlated with acute COVID-19 severity, and anxiety, depression, and quality of life ≥ 6 months post-infection. Specifically, obesity (BMI > 30), has been previously identified as a risk factor for COVID- 19 regarding severity and mortality. We found it imperative to further investigate these demographic variables, as they are vital in understanding how social determinants of health are impacting COVID-19 outcomes. Insights from this study can assist with identifying gaps in care for those with poor social determinants of health, as well as help shape care for those who have been disproportionately affected. METHODS: We examined records of COVID-19 patients through the COVID-19 Recovery Clinic at George Washington University in Washington, D.C. that has been collecting data on patient short and long-term COVID-19 outcomes in various domains along with demographic information since November 2020. Using RStudio with calculations of descriptive data, odds ratios, and p-values using Fisher's exact test, we assessed education level, income, race, ethnicity, and obesity and looked at how they correlated with COVID-19 severity at diagnosis, presence of anxiety, depression and quality of life ≥ 6 months after acute infection. RESULTS: From our sample (n=150), we found African Americans had greater acute COVID-19 severity (OR=7.56, 95% CI 2.22, 25.68, p=0.0015) relative to white individuals. We also found that obesity was associated with higher levels of acute COVID-19 severity (OR=4.89, 95% CI 1.36, 17.60, p=0.022).Additionally, during acute COVID-19 infection, 7/32 (21.9%) obese patients compared to 9/112 (8.0%) non-obese patients were hospitalized (OR=3.79, 95%CI=1.23, 11.68, p=0.03).No significant association was found between anxiety, depression, quality of life or COVID- 19 severity and persistent symptoms. CONCLUSIONS: We observed associations between the African American race and more severe acute COVID-19 infection. Further, in the acute phase, we observed that obese patients were more likely than non-obsese patients to have more severe infection and be hospitalized. These findings highlight preexisting gaps in healthcare outcomes regarding social determinants of health. It is essential to analyze many of the potential longer-term effects of COVID-19 infection, as they remain poorly understood. We conclude that larger studies are necessary to better understand the effects of social determinants of health on both short and long-term outcomes of COVID-19.

ABSTRACT

BACKGROUND: During the COVID-19 pandemic, most attention has been focused on the acute phase of the disease, but lingering symptoms from the postacute sequelae of COVID-19 (PASC) merit concern. The George Washington University COVID-19 Recovery Clinic is documenting these presentations to better understand PASC and its precipitating factors. The group implemented definitions for six phenotype categories: pulmonary, cardiac, connective tissue, vascular, central nervous system (CNS), and other. This research seeks to identify pre-existing factors that could affect disease severity, understand their effect on PASC symptoms at 6-15 months post-infection, and determine associations between patient history and PASC phenotypes. METHODS: An IRB-approved, retrospective cohort study was performed from charts of adult patients with persistent symptoms after acute COVID-19. Data were ed from clinical history prior to COVID-19 diagnosis, during acute COVID-19, and during the post-acute phase, including laboratory results and responses from mental health assessment tools. PASC phenotypes were determined clinically and hospitalization was used as a proxy for disease severity. Descriptive statistics, unadjusted odds ratios, and significance tests (Fisher's exact test, Chi-square test, and Mann-Whitney U test) were calculated using RStudio (4.1.1). RESULTS: Study participants with persistent symptoms at 6-15 months postinfection (n=116) had a mean age of 45.16 (SD 13.23), of which 70% were female, 60% were Caucasian, 12% were African-American, 9% were Asian, and 3% were Hispanic/Latino. When including all patients who had persistent symptoms at 1-15 months post-infection, those with obesity (BMI ≥30) or type 2 diabetes were much more likely to undergo a severe acute phase of COVID19 (OR 12.75;95% CI 1.91-84.95;p=0.02;n=61 and OR 34.67;95% CI 4.43-271.46;p<0.001;n=61 respectively). At 6-15 months post-infection, those suffering from a pulmonary PASC phenotype were more likely to have smoked (OR 3.27;95% CI 1.18-9.11;p=0.02;n=91). At the same period, those presenting with at least one CNS phenotype had a significantly higher level of C-reactive protein (CRP) than those without a CNS phenotype presentation (Mean 3.70 mg/L, SD 5.19 vs. Mean 1.26 mg/L, SD 2.36;p=0.009;n=53). Additionally, acute phase severity was not significantly associated with the presence of PASC. CONCLUSIONS: Our research further demonstrates the increased risk of severe acute COVID-19 among patients with obesity and type 2 diabetes. Furthermore, we show that those with a smoking history were more likely to continue to have pulmonary symptoms of COVID-19 at 6-15 months postinfection. Additionally, our study suggests that there may be a relationship between CRP and persistent CNS symptoms. A better understanding of these associations can help predict the full burden of COVID-19 and improve clinical guidance.

ABSTRACT

Introduction: In March 2020, Coronavirus Disease 2019 (COVID-19) was declared a pandemic. Elective healthcare services were reorganised worldwide. This study addresses the impact of measures taken in the early stages of the pandemic on diagnosing Upper Gastrointestinal (UGI) and Hepatopancreaticobiliary (HPB) malignancies in a university teaching hospital. Aims: To ascertain whether fewer cases of UGI/HPB cancers were detected, the differences in inpatient and outpatient diagnosis and whether there was an increased detection of later stage disease during the pandemic than in the preceding year. Methods: This was a retrospective cohort study conducted in Tallaght University Hospital in Ireland. All new diagnoses of UGI/HPB cancers, excluding hepatocellular carcinomas, are managed at a weekly Multidisciplinary Team (MDT) meeting. Data was retrieved from the MDT database and medical records and analysed using IBM SPSS Statistics V20. Results: 111 cases were detected. There was no significant difference in the proportion of cases detected in the overall post-COVID period (n=53, 47.7%) compared to the Pre-COVID period (n=58, 52.3%) (p=0.7884). When COVID-19 cases were at their highest levels in Ireland, we observed a significant drop in new UGI/HPB cases detected compared to the pre-COVID period. This was mitigated in the third quarter of 2020, when transmission was depressed and a sharp increase in detection of UGI/HPB cases was observed. The variance of distribution of cases per quarter in the two periods was statistically significant with a P-value of 0.0001. There was a non-significant trend towards fewer diagnoses of early cancer (stage ≤2) in the Post- COVID period (21% v 26%) (p=0.6416). The proportion of patients diagnosed as an inpatient did not differ between the two periods, p=.739. Discussion: As fears about aerosolization abated, endoscopy services quickly increased the number of scopes performed after the initial reduction at the start of the pandemic. There are several limitations to this study, however it does lead us to conclude that our fears regarding cancer diagnosis in the postpandemic period did not materialise. It also offers solace that when transmission of COVID- 19 is depressed, as it was in Ireland in Q3 2020 before the peak of the second wave in Q4 2020, that outpatient services can quickly escalate their level of activity and detect cancers that were missed with no significant change in stage. A further observation is that when lockdown measures in Ireland were reintroduced in winter 2020/2021 but outpatient services were kept open, a similar reduction in detections was observed compared to when they were closed. Therefore, the question may be posed if the primary driver of reduced detection of UGI/HPB cancers is primary care services being overwhelmed with pandemic work rather than a reduction in outpatient services .

ABSTRACT

The buddy system, where a pair of divers look out for one another, is used by the diving community to mitigate danger. They inspect each other's breathing apparatus, monitor remaining air supplies, health status, and can provide emergency support during a dive. Due to buddy unavailability however, some divers dive solo, forgoing the safety aspects of the buddy system. We propose a dedicated dive-buddy robot as a solution to this problem. The robot, an autonomous underwater vehicle, could operate as an assistant, controlled by the diver using hand gesture-based communication;a communication method commonly used amongst divers. To capture the gestures, we have developed a smart dive glove integrated with 5 dielectric elastomer strain sensors. The capacitance of each sensor was measured with on-board electronics, translated into a command using machine learning and transmitted underwater using acoustics. Due to travel restrictions relating to the Covid-19 pandemic, a demonstration with the diver and vehicle in the same pool was not possible. Therefore, here we present a demonstration with the diver performing gestures in a pool in Auckland, New Zealand, sending commands to the robot in a pool in Zagreb, Croatia. The commands were sent through acoustics to a computer in Auckland, over cellular internet to a computer in Zagreb, which then relayed instructions to the robot using acoustics. The robot was sent four commands and successfully completed all manoeuvres. The performance of the communication with regards to time delays is assessed and future improvements are discussed. © 2022 SPIE.

ABSTRACT

Background/Aims The COVID-19 pandemic forced rheumatology clinics to utilise telephone consultations as a means to limit footfall at hospitals and to protect our vulnerable patients. This was a new mode of service delivery for most rheumatology departments as previously all appointments used to be face-to-face. Although remote consultations were previously being considered as a mode of service delivery, the COVID-19 pandemic has expedited the uptake remote consultations within a very short span of time. There are no systematic studies to compare the effectiveness of remote consultations versus face-to-face consultations although remote consultations are now being widely adopted. Our aim was to assess the effectiveness of telephone consultations compared to face-to-face consultations in the routine review of rheumatology patients. Methods 101 face-to-face consultations and 98 telephone consultations were randomly selected from the months of June and August in 2019 and 2020 respectively. The clinic letters were then accessed and the clinic outcomes were noted. The parameters chosen to aid comparison included start of new medication, medication dose changes, referral for investigations, referral to another specialty, referral to MDT, referral for a steroid injection, timescale of subsequent follow up and discharge from services. Results The main results broadly showed similarities in case-mix and several outcomes, including time scale of follow up and intra-articular and intramuscular steroid injections. Fewer patients were started on a new medication following a telephone consultation (14.9% vs 10.2%), more patients had their current medication dose changed (14.9% vs 17.3%) and slightly more patients were referred for investigations (25.7% vs 30.6%). Furthermore, telephone consultations resulted in a lower rate of referrals to MDT (13.9% vs 5.1%) and marginally fewer discharges. Conclusion The evaluation showed there were clear similarities between the two groups which showed telephone consultations were comparable to face-to-face consultations. Out of the 98 telephone consultations, only 10 were converted to a face-to-face appointment which was lower than many had predicted. However, the drop in referral rates to other specialties may represent that consultants do not feel confident to refer to another team without a comprehensive face-to-face assessment. Telephone consultations, with the back up of face-to-face slots made available for appropriate patients, appear to be an effective means of service delivery and is likely to continue in a scaled down form.

ABSTRACT

Background. More than half of all hospitals in the U.S. are rural hospitals. Frequently understaffed and resource limited, community hospitals serve a population that tends to be older and have less access to care with increased poverty and medical co-morbidities. There is a lack of data surrounding the impact of COVID-19 among rural minority communities. This study seeks to determine rural and urban disparities among hospitalized individuals with COVID-19. Methods. This is a descriptive, retrospective analysis of the first 155 adult patients admitted to a tertiary hospital with a positive COVID-19 nasopharyngeal PCR test. Augusta University Medical Center serves the surrounding rural and urban counties of the Central Savannah River Area. Rural and urban categories were determined using patient address and county census data. Demographics, comorbidities, admission data and 30-day outcomes were evaluated. Results. Of the patients studied, 62 (40%) were from a rural county and 93 (60%) were from an urban county. No difference was found when comparing the number of comorbidities of rural vs urban individuals;however, African Americans had significantly more comorbidities compared to other races (p-value 0.02). In a three-way comparison, race was not found to be significantly different among admission levels of care. Rural patients were more likely to require an escalation in the level of care within 24 hours of admission (p-value 0.02). Of the patients that were discharged or expired at day 30, there were no differences in total hospital length of stay or ICU length of stay between the rural and urban populations. Conclusion. This study suggests that patients in rural communities may be more critically ill or are at a higher risk of early decompensation at time of hospitalization compared to patients from urban communities. Nevertheless, both populations had similar lengths of stay and outcomes. Considering this data is from an academic medical center with a large referral area and standardized inpatient COVID-19 management, these findings may prompt further investigations into other disparate outcomes.

ABSTRACT

By June 2020, Marshallese and Hispanic or Latino (Hispanic) persons in Benton and Washington counties of Arkansas had received a disproportionately high number of diagnoses of coronavirus disease 2019 (COVID-19). Despite representing approximately 19% of these counties' populations, Marshallese and Hispanic persons accounted for 64% of COVID-19 cases and 57% of COVID-19-associated deaths. Analyses of surveillance data, focus group discussions, and key-informant interviews were conducted to identify challenges and propose strategies for interrupting transmission of SARS-CoV-2, the virus that causes COVID-19. Challenges included limited native-language health messaging, high household occupancy, high employment rate in the poultry processing industry, mistrust of the medical system, and changing COVID-19 guidance. Reducing the COVID-19 incidence among communities that suffer disproportionately from COVID-19 requires strengthening the coordination of public health, health care, and community stakeholders to provide culturally and linguistically tailored public health education, community-based prevention activities, case management, care navigation, and service linkage.

ABSTRACT

Introduction: Coronavirus has been responsible for several virus outbreaks since 2003, caused by SARSCoV-1, MERS-CoV, and currently SARS-CoV-2 (COVID-19), the causative agent of coronavirus disease in 2019. COVID-19 has become a global public health emergency because of its high virulence and mortality capacity. This patent review aims to provide an overview of the patents that present possible treatments for SARS-CoV-1, SARS-CoV-2 and MERS-CoV. Areas covered: To treat SARS, MERS and SARS-CoV-2, researchers have filed patents for a number of therapeutic agents. Most of the treatments found were protease inhibitors aimed at proteases such as PLpro, 3 CLpro, RNA helicase, and Spike protein, or used monoclonal antibodies and interferons. In addition, the use of Chinese folk medicine and its multitude of medicinal plants with strong antiviral properties was reinforced. Thus, these therapies used in previous epidemics can serve as an aid in the new pandemic by SARS-CoV-2 and be a starting point for new treatments. Expert opinion: The various antiviral alternatives presented in this review offer therapeutic options to fight coronavirus infections. If shown to be effective, these drugs may be extremely important in the current pandemic.

ABSTRACT

Introduction: COVID-19 induces a pro-inflammatory, hypercoagulable state with marked elevations of ferritin, C-reactive protein, interleukin, and D-dimers. Observed consequences include pro-thrombotic disseminated intravascular coagulation (DIC) with a high rate of venous thromboembolism (VTE) and elevated D-dimers with high fibrinogen and low anti-thrombin levels. Pulmonary congestion appears to be due to micro-vascular thrombosis and occlusion on pathological examination.1 The acquired pro-thrombotic state and associated poorer outcomes seen in critically ill COVID-19 patients 2,3 have led to such patients being treated empirically with systemic anticoagulants. Unfractionated heparin (UFH) or low molecular weight heparin (LMWH) have both been used.2,3 Methods: Review of COVID-19 positive adult patients admitted to the critical care unit between 10th March and 13th May 2020 with severe respiratory failure requiring invasive ventilation. Results: In that period we admitted 59 patients. 6 (10%) females, 56 (90%) males. 45 (76%) patients required therapeutic anticoagulation (27 UFH, 14 LMWH, 4 argatroban). 4 (8.9%) of the 45 anticoagulated patients suffered catastrophic intracranial haemorrhage and subsequently died. Discussion: The risk for any significant haemorrhage in patients systemically anticoagulated for VTE with unfractionated heparin (UFH) is 2-3%, 4 and that of anticoagulant-related intracranial haemorrhage (AICH) in patients systemically anticoagulated with UFH is 1-2.7% (in patients treated for ischaemic stroke) and 4% with argatroban.5 We report a much higher incidence of nearly 9%. The cases we present fulfilled the advised criteria for systemic anticoagulation. Despite four-hourly monitoring of APPT and anti-Xa activity on the intensive care unit there were significant fluxes in these laboratory markers of anticoagulation. These may be associated with the uncharted nature of this disease process.It is impossible to disassociate the necessary therapeutic-intensity anticoagulation with the observed heightened frequency of life-ending intracranial haemorrhage in these patients.

ABSTRACT

OBJECTIVES: To report feasibility, early outcomes and challenges of implementing a 14-day threshold for undertaking surgical tracheostomy in the critically ill coronavirus disease 2019 patient. METHODS: Twenty-eight coronavirus disease 2019 patients underwent tracheostomy. Demographics, risk factors, ventilatory assistance, organ support and logistics were assessed. RESULTS: The mean time from intubation to tracheostomy formation was 17.0 days (standard deviation = 4.4, range 8-26 days). Mean time to decannulation was 15.8 days (standard deviation = 9.4) and mean time to intensive care unit stepdown to a ward was 19.2 days (standard deviation = 6.8). The time from intubation to tracheostomy was strongly positively correlated with: duration of mechanical ventilation (r(23) = 0.66; p < 0.001), time from intubation to decannulation (r(23) = 0.66; p < 0.001) and time from intubation to intensive care unit discharge (r(23) = 0.71; p < 0.001). CONCLUSION: Performing a tracheostomy in coronavirus disease 2019 positive patients at 8-14 days following intubation is compatible with favourable outcomes.
