Severe Dengue With Multisystem Inflammatory Syndrome in Children Due to COVID-19: A Co-infection Case Series

Severe dengue with the multisystem inflammatory syndrome in children (MIS-C) can be difficult to diagnose as both diseases have similar symptoms and laboratory findings. Bangladesh is currently facing a double burden of severe dengue and SARS-CoV-2 infection. Co-infection with these viruses can result in severe morbidity. Worldwide this co-infection is rare. However, we present five cases of severe dengue with possible MIS-C due to SARS-CoV-2 infection in children. All the children presented with shock with variable degrees of plasma leakage. Mucocutaneous and gastrointestinal involvement were common. All tested positive for dengue nonstructural protein 1 antigen on the second to the third day of fever and tested positive for anti-SARS-CoV-2 IgG by enzyme-linked immunosorbent assay. Echocardiographic evaluation in all patients showed coronary arterial abnormalities. Cardiac enzymes were abnormal, and there were raised inflammatory markers and abnormal coagulation profiles. One patient had neurological involvement and needed mechanical ventilatory support. All cases were successfully managed according to dengue shock syndrome guidelines and required intravenous immunoglobulin with prednisolone, aspirin, and in some cases, enoxaparin for the management of coronary arterial involvements, which is not a documented feature for severe dengue infection, but typically found in MIS-C due to SARS-CoV-2 infection or Kawasaki disease. This case series aims to describe the possibility of co-infection of severe dengue with MIS-C due to SARS-CoV-2 infection in a dengue-endemic region during the coronavirus disease 2019 (COVID-19) pandemic, and alternatively, dengue virus as an unusual etiology for Kawasaki disease was also entertained. Severe dengue in endemic regions can coexist with COVID-19 during an outbreak, making it hard to diagnose. It can be fatal without early, appropriate management.

Working at Home: The Impacts of COVID 19 on Health, Family-Work-Life Conflict, Gender, and Parental Responsibilities

OBJECTIVE

To examine the impact of working at home on general health, pain, stress, and work-family and family-work conflict, and differences based on gender and parental responsibilities.

METHODS

A convenience sample of 658 adults completed an online questionnaire. Regression modeling examined the effects and interactions of gender and parental responsibility on general health, musculoskeletal discomfort/pain frequency and severity, stress, and work-family and family-work conflict.

RESULTS

Women reported more pain and discomfort, regardless of the presence of children, than men with children. Women with children experienced increased stress compared with men with children. Women without children experienced less work-family conflict, and those without children experienced less family-work conflict than men with children.

CONCLUSIONS

The impact on pain, stress, and work-family and family-work conflict, due to mandated working at home, is gendered and influenced by parental responsibilities.

Warm and Cold Autoimmune Hemolytic Anemia in the Setting of COVID-19 Disease

Known associations with autoimmune hemolytic anemia (AIHA) include lymphoproliferative neoplasms, autoimmune conditions, and viral infections. There are a few case reports that implicate a potential relationship between COVID-19 and either warm or cold AIHA. We present the case of combined warm and cold AIHA in the setting of COVID-19. A 51-year-old male with no known past medical history presented with weakness and jaundice. Initial workup revealed white blood cells 41.4, hemoglobin 3.1, platelets 343, total bilirubin 5.3, direct bilirubin 1.6, and COVID-19 positive. Direct antiglobulin test (DAT) found IgG and C3 antibodies and pathology revealed cold agglutinins, consistent with both warm and cold AIHA. He received a total of five blood transfusions and was started on prednisone 1 mg/kg daily with a gradual taper over months. Hemolysis labs normalized within two weeks after discharge although antibodies remained positive 70 days after admission. Our patient presented with IgG and C3 antibodies as well as cold agglutinins, consistent with both warm and cold AIHA. To our knowledge, this is the first case of both warm and cold AIHA presenting simultaneously in COVID-19 infection. Unlike most cases in the existing literature, this patient had no history of underlying hematologic malignancy and both warm and cold AIHA.

Asymptomatic Rhabdomyolysis in a Young Adult With COVID-19

The novel coronavirus disease 2019 (COVID-19) is an ongoing pandemic. Although COVID-19 is frequently associated with respiratory symptoms and complications, multiple extrapulmonary manifestations have been identified since the beginning of the pandemic. Rhabdomyolysis has been described in the literature as one of the extrapulmonary manifestations of COVID-19. Herein, we describe a 21-year-old male patient who presented with cough and fever secondary to COVID-19 confirmed by positive reverse-transcription polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The patient presented with an extremely elevated creatinine kinase (CK) of 53,886 U/L (normal 10-170) without any classical symptoms of rhabdomyolysis or deterioration in his kidney function. He was successfully managed with aggressive intravenous fluids. The aim of reporting this case is to highlight the importance of including total CK in the initial evaluation of COVID-19 patients.

COVID-19 Rekindling Herpes Zoster in an Immunocompetent Patient

During the coronavirus 2019 (COVID-19) pandemic, sundry dermatological conditions related to COVID-19 pneumonia have been published. COVID-19 primarily affects the respiratory system, but secondarily it also affects the heart, kidney, brain, skin, spinal cord, etc. Herpes Zoster (HZ) is considerably important morbidity associated with COVID-19 pneumonia. Recrudescence of HZ occurs because of the latent varicella-zoster virus (VZV) predominantly because of the decline in cell-mediated immunity (CMI). Abating CMI is due to the increasing age, but could also occur if the patient is suffering from an immunosuppressive disease or is using immunosuppressive drugs. In our case, the patient had no lymphopenia unlike the other cases, yet still, he developed HZ. HZ is associated with post-herpetic neuralgia (PHN), HZ ophthalmicus (HZO), and cerebral arteritis increasing morbidity and mortality, especially in elderly people and those who are immunocompromised.

Acute Mesenteric Ischemia as an Early Complication of COVID-19

We herein report a case of a 44-year old male patient with coronavirus disease 2019 (COVID-19) who presented with acute mesenteric ischemia. Acute mesenteric ischemia presents with severe abdominal pain, vomiting, and constipation. The case consisted of features typical of acute mesenteric ischemia. The patient underwent laparotomy with resection of a gangrenous segment of the bowel. The radiological features of the injury along with the pathophysiology and management have been discussed.

The Emergence of New-Onset Obsessive and Compulsive Disorder in an Adolescent During COVID-19 Pandemic

The COVID-19 pandemic has had a huge toll on both the physical and mental health of people around the globe. Neuropsychiatric symptoms, as well as long-term sequelae, have been demonstrated in those afflicted with COVID-19. These symptoms range from cognitive, attention deficit, new-onset anxiety, depression, psychosis, seizures, and post-traumatic stress. Prolonged lockdown led to social isolation which negatively affected the mental well-being of many individuals. This particularly caused a relapse of psychiatric symptoms due to stress related to the COVID-19 pandemic. It sparked an increase in hoarding behaviors such as obtaining germicidal and cleaning supplies. In this report, we present a case of an adolescent male presenting with a new onset of obsessive-compulsive disorder with symptoms similar to olfactory hallucinations and olfactory reference syndrome in the setting of the COVID-19 pandemic.

A Late Presentation of COVID-19 Vaccine-Induced Myocarditis

With the introduction of the coronavirus disease 2019 (COVID-19) mRNA vaccines, the incidence of severe infection has significantly decreased. While the vaccines have been shown to be effective and safe, there have been few case reports of acute myocarditis within 3-5 days following the second dose of the vaccine. We report a case of an elderly man who presented with acute-onset chest pain after three months of receiving the second dose of the mRNA vaccine. He was found to have acute myocarditis on cardiac magnetic resonance imaging (CMRI), which was attributed to exposure to the COVID-19 vaccine in the absence of any other risk factors. Our patient demonstrated quick resolution of symptoms and was discharged within 72 hours. We review the literature and summarize published case reports on COVID-19 vaccine-associated myocarditis. The present case report provides new evidence regarding the possible subacute presentation of myocarditis post-COVID-19 vaccine, and further highlights the favorable outcome in this newly described clinical entity.

Parvovirus Reactivation in COVID-19

Anemia is a diagnostic challenge in patients with coronavirus disease 2019 (COVID-19). This is due to the broad differential of etiologies for anemia, which includes bleeding, bone marrow suppression secondary to sepsis, and hemolytic anemia. Here, we present a first-ever case of otherwise unexplained anemia in a patient receiving treatment for COVID-19 secondary to parvovirus B19 reactivation. While parvovirus infections often present as acute states of anemia, this patient developed a case of reactivation secondary to immunosuppression from COVID-19 treatment. This case indicates the importance of assessing for parvovirus infections in COVID-19 patients with otherwise unexplained anemia.

A New and Rare Presentation of Unilateral Recurrent Laryngeal Nerve Palsy in a COVID-19 Patient With No Recent History of Endotracheal Intubation

The Coronavirus disease 2019 (COVID-19) infection has classical symptoms of high fevers, diarrhea, cough, and dyspnea; however, there are cases recording more unconventional features. In this case report, we will discuss recurrent laryngeal nerve palsy as a new and unusual presentation of COVID-19. The patient was a 58-year-old African American male with a history of hypertension, type-2 diabetes mellitus, and obstructive sleep apnea presenting with dyspnea, fatigue, and nausea. The patient was initially admitted to the medical intensive care unit (MICU) for acute hypoxic respiratory failure and completed intravenous Remdesivir for COVID-19. He never got intubated during the ICU stay and his condition improved on the 34th day of admission. However, two weeks later the patient suddenly developed hoarseness of voice. A bedside laryngoscopy revealed a left-sided vocal cord paralysis but patent airway. The computed tomography (CT) scan of the neck did not show any abnormalities, including any impinging masses or structures. The patient did not have any recent intubations to suggest the paralysis was due to traumatic injury, thus favoring that his neurologic injury was likely a post-viral symptom. One possible pathophysiology would be the invasion of nerve fibers (peripheral or cranial nerves) by the virus using the same mechanism as seen in alveolar cells and finally destroying them. Another hypothesis would be the inflammatory response of the host immune system affecting the peripheral and cranial nerves. Therefore, the potential association between neuro-invasiveness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the recurrent laryngeal nerve palsy resulting in the vocal cord paralysis should be considered and more studies need to be conducted for better understanding.

A Case Series of SARS-CoV-2 and Influenza Co-infection

The novel coronavirus 2019, a disease associated with SARS-CoV-2 infections has resulted in significant morbidity and mortality across the globe. In the United States, influenza has been one of the leading causes of hospitalization during the winter season. To date, the co-infection of SARS-CoV-2 and influenza virus has created a unique challenge for healthcare workers, especially during the cold season. Both viruses have similar clinical presentation and transmission characteristics. Many reports are available for either SARS-CoV-2 and influenza individual infections, but limited data are available for the co-infection. Herein, we present a case series of five cases of SARS-CoV-2 and influenza co-infection as well as their clinical characteristics, laboratory findings, management, and outcome.

Long COVID Syndrome and Takotsubo Cardiomyopathy: An Unwelcome Combination

Since the report of the first case from China in late 2019, the coronavirus disease (COVID-19) has spread very rapidly through the countries and regions leaving a trail of devastation in its path, everywhere. Although COVID-19 is primarily a respiratory illness mainly affecting the lungs; involvement of other organs including the cardiovascular system has been widely recognized. Whilst COVID-19 is an acute illness for a majority of cases; some of the debilitating virus-related symptoms can last for weeks and months, and are collectively termed as long COVID syndrome. Several published reports have described an association between acute COVID-19 illness and cardiac complications such as myocarditis and Takotsubo cardiomyopathy. However, little is known about any link between long COVID syndrome and the cardiac disease. We describe the case of a middle-aged woman with long COVID syndrome who presented with central chest pain and breathlessness. Her initial investigations showed an elevated cardiac troponin I and ischemic changes on 12 lead ECG. She was initially treated for non-ST elevation myocardial infarction. A subsequent coronary angiogram showed unobstructed coronary vessels and left ventricle (LV) gram demonstrated apical LV ballooning. She was managed conservatively and was discharged home following her clinical improvement. This case highlights the importance of holistic assessment of patients presenting with chest pain with the background of long COVID syndrome. It also outlines an emergent need to better understand pathophysiological mechanisms that underpin the development of cardiac complications in those with COVID-19 and long COVID syndrome.

Thrombosis of Bilateral Profunda Femoris, Anterior Tibial, and Tibioperoneal Arteries in a Patient With COVID-19 Infection

COVID-19, also known as severe acute respiratory distress syndrome coronavirus 2, mostly affects the respiratory system causing acute respiratory syndrome. It not only targets lungs but also causes vascular endothelial disruption, which can lead to arterial or venous thrombosis causing ischemia, which increases the morbidity and mortality in some patients, if not recognized and treated in a timely manner. We present an interesting case of a patient recovering from COVID-19 pneumonia , who developed bilateral foot ischemia due to thrombosis of bilateral profunda femoris, bilateral anterior tibial, and tibioperoneal arteries.

A 44-year-old gentleman presented to the emergency department complaining of severe bilateral foot pain, which progressively got worse. Upon examination he had blue toes bilaterally with absent dorsalis pedis and posterior tibial pulse. CT angiogram was performed, which showed severe multilevel lower limb arterial occlusions involving bilateral profunda femoris, bilateral anterior tibial, and tibioperoneal arteries. The patient was initially thrombolyzed and later underwent thrombectomy with the assistance of interventional radiologist. Hospital course was uneventful, and the patient was discharged on warfarin following complete resolution of symptoms.

Acute COVID-19 Cerebellitis: A Rare Neurological Manifestation of COVID-19 Infection

The COVID-19 virus is well known to cause respiratory tract infections but several non-respiratory presentations and post-infectious complications have been well reported since its origin. With this case report, we present a rare manifestation of COVID-19 infection that presented as acute cerebellitis. This is a case of a 63-year-old Caucasian male patient who presented with altered mental status and ataxia. He was diagnosed with COVID-19 infection about five days prior to presenting to the hospital. Neurological exam was consistent with cerebellar symptoms like broad bases gait, truncal ataxia and subsequent imaging revealed white matter degeneration and edema of the cerebellar hemispheres. The symptoms completely resolved following treatment of ongoing COVID-19 infection with corticosteroids and intravenous remdesivir. With this case report, we intend to discuss the available literature regarding the clinical manifestations, management, and prognosis of COVID-19-induced cerebellitis.

Extra-Articular Manifestations in Reactive Arthritis due to COVID-19

Reactive arthritis (ReA) is defined as arthritis that arises after infection, where pathogens cannot grow in the affected joints. Formerly, the clinical triad of postinfectious arthritis, urethritis, and conjunctivitis was called Reiter's syndrome; however, these clinical signs only represented a subset of patients with ReA. Due to the great diversity of its manifestations, its diagnosis is a challenge and can be overlooked in clinical practice. Additionally, it is associated with a variety of extra-articular manifestations that may be present either in the acute or chronic phase of the disease. Despite the cardinal clinical presentation characteristics of ReA, no case has been described in the literature that is diagnosed by the presence of classic extra-articular manifestations without objective joint involvement after COVID-19 infection. This report describes the case of a female patient in her third decade of life with an unusual presentation of ReA and focuses on her extra-articular manifestations.

Bilateral Thalamic Stroke: A Case of COVID-19 Vaccine-Induced Immune Thrombotic Thrombocytopenia (VITT) or a Coincidence Due to Underlying Risk Factors?

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare but potentially life-threatening side effect that has only been observed in adenovirus-based vaccines for coronavirus disease 2019 (COVID-19). VITT is an immune-mediated condition that generally presents within five to 10 days post-vaccination with thrombosis, thrombocytopenia, and coagulation abnormalities. A diagnosis of VITT is made clinically and through laboratory testing. Although VITT is an important differential to consider, it is believed that more emphasis should be placed on vaccination due to the safety and efficacy in overcoming COVID-19.

Dermatological Manifestations of COVID-19 in Patients Reporting to a Tertiary Care Hospital in Rawalpindi, Pakistan

Introduction The clinicopathological description of dermatological manifestations of COVID-19 leaves much to be desired. There is a need to determine their association with disease severity, outcome, and other clinical variables. Objectives The objectives of this study are to record and histopathologically examine the cutaneous manifestations of COVID-19 and correlate these to age, disease severity, and mortality. Methods All confirmed COVID-19 patients admitted to a single tertiary healthcare hospital in Rawalpindi, Pakistan, were included. Their diseases were classified as mild, moderate, severe, and critical. The recent onset skin eruptions in these patients were recorded via photographs along with relevant clinical data. The photographs were independently reviewed by a group of three dermatologists without knowledge of the clinical information. The skin manifestations were divided into disease-specific and nonspecific categories using an already defined algorithm. Histopathological examination of skin manifestations was conducted. Results A total of 23% (n=47) had "new" skin manifestations. Specific skin findings were seen in 21.6% (n=44), which consisted of ecchymosis/purpura in 50% (n=22), maculopapular exanthem in 18% (n=8), livedo reticularis in 16.2% (n=7), ischemia/gangrene in 16.2% (n=7), perniosis in 15.9 % (n=7), vesiculo-bullous rash in 9% (n=4) and urticaria in 4% (n=1). Non-specific findings were seen in 6% (n=13) and included bedsores, dermatitis passivata, dryness, herpes labialis, oral ulcerations, and nasogastric tube-induced ulcerations. There was a significant association (p=0.03) between disease severity and specific skin lesions. Ischemia/gangrene was significantly associated with COVID-19 disease severity and mortality. Vesiculobullous lesions were associated with higher mortality, though not with disease severity. Livedo reticularis had a higher-than-expected count in critical disease, albeit statistically insignificant. The association of maculopapular exanthem and ecchymosis/purpura with severe/critical disease was statistically insignificant. Urticaria was significantly associated with low disease severity. Mean age with specific manifestations was 56.86 ± 15.81 and with nonspecific/without any manifestations was 42.58 ± 16.96, a highly significant difference, with p-value < 0.001. Old age (>60 years) was significantly associated with ecchymosis (p=0.038), maculopapular exanthem (p=0.021), and vesiculo-bullous rash (p=0.029). Histopathology varied according to the type of skin lesion. Conclusions Dermatological manifestations coexist in many patients and tend to appear more in severe cases of COVID-19 among the older age group and only minimally in mild/moderate cases. Their presence could help set prognostic criteria of COVID-19 disease in the future.

Aortic thrombosis associated with COVID 19 pneumonia

Coronavirus disease 19 (COVID-19) predispose to both venous and arterial thrombotic events, especially in severe patients. There are reports of lowe risk patients whose courses are complicated by arterial thrombosis. We report the case of 53 year-old woman who presented  with severe acute respiratory syndrome due to COVID-19 with descending aortic thrombosis. The evolution was favorable under anticoagulant treatment.

Post-traumatic Stress Disorder Among Healthcare Workers Diagnosed With COVID-19 in Jeddah, Kingdom of Saudi Arabia, 2020 to 2021

Background

Post-traumatic stress disorder (PTSD) is a global problem. According to its definition, it is a disorder that occurs with some people who have undergone or witnessed a shocking, terrifying, or hazardous event, and the coronavirus disease (COVID-19) with its consequent threats and fear meets the definition of a traumatic event. The main aim of this study is to determine PTSD in healthcare workers (HCWs) who survived COVID-19 in Jeddah, Saudi Arabia.

Subjects and methods

Through an analytical cross-sectional study, HCWs working in Jeddah city with a minimum of seven days since their first positive COVID-19 result were included in this study. They were screened using the 'PTSD checklist for The Diagnostic and Statistical Manual of Mental Disorders (DSM-5)' (PCL-5), which is a 20-item self-report measure that assesses the presence and severity of PTSD symptoms.

Results

Out of all respondents (n=404), there was slight dominance of females (54.0%) over males (46.0%), and an almost equal distribution of Saudis (51.2%) and non-Saudis (48.8%); their mean age accounted for 36.9±8.7 years. PTSD was detected in 14.9%; the prevalence was significantly higher in those who had chronic diseases (23.7%), especially diabetics (30.8%) and obesity (41.2%), HCWs whose job necessitates exposure to positive cases (18.8%), and those who were isolated in hospitals while being ill. All the above values were statistically significant (p<0.05). 

Conclusion and recommendations

The prevalence of PTSD in the HCWs who survived COVID-19 came within the range of that in HCWs who were dealing with cases of COVID-19 without being affected. Efforts should be made to alleviate stress in HCWs during their work in pandemics.

New-Onset Psychosis Following COVID-19 Infection

Previous studies have suggested that some individuals experience neuropsychiatric symptoms following coronavirus disease 2019 (COVID-19) infection. We describe a case of new-onset psychosis following COVID-19 infection in a 55-year-old female with no prior psychiatric history. The patient started exhibiting symptoms of COVID-19 infection three weeks prior and was treated in the hospital with 4 L oxygen, dexamethasone 6 mg, and remdesivir therapy for seven days. Throughout her hospital stay, the patient had no neuropsychiatric symptoms. During her last week of stay, she was solely getting oxygen at home before presenting to the emergency department (ED) with severe psychosis. Her COVID-19 test in ED presentation was negative, and all potential etiologies for psychosis were ruled out. She was effectively treated for two weeks with 10 mg haloperidol and 1000 mg sodium valproate daily, followed by outpatient care. While variables such as a family history of bipolar disorder, psychosocial stressors, and steroid medication may have contributed to the patient's presentation, these circumstances alone did not result in neuropsychiatric symptoms in the past. COVID-19 infection may enhance the likelihood of developing neuropsychiatric problems on its own or amplify the effects of risk factors associated with an increased risk of psychosis. Neuropsychiatric consequences of COVID-19 infection may be under- or over-reported in individuals treated with steroids. Further research is necessary to identify individuals at risk of experiencing neuropsychiatric issues owing to COVID-19 infection and the prognosis.

Evaluating the Integrated Plastic Surgery Residency Match During the Novel Coronavirus Pandemic

The COVID-19 pandemic had significant impacts on medical education and on the 2021 Match. Visiting student rotations at locations other than students' home institutions were cancelled and residency interviews were hosted virtually. This study evaluated the impact that COVID-19 had on the 2021 Match including residency programs matching applicants from within their own institution as well as from within the same region. The sex of matched applicants in the Match cycles was analyzed as well. Data were collected from residency program websites, social media accounts, and communication with current residents. Data were tabulated and chi-square analysis was performed. The overall difference in matched internal candidates pre-/post-pandemic was determined to be statistically significant (8.3% increase; p = 0.004). The Midwest was determined to exhibit a significant increase for matching residents from medical schools in the same region (15.6% increase; p = 0.04). Female applicants were also determined to be significantly more likely to match into integrated plastic surgery programs in 2021. COVID-19 significantly impacted the 2021 Match with an increased number of programs selecting internal candidates, matched female applicants, and regional selectivity, especially in the Midwest. It is our hope that applicants, programs, and the plastic surgery community will use this information to continue to improve the residency selection process in the future.

COVID-19, Necrotizing Pancreatitis, and Abdominal Compartment Syndrome: A Perfect Cytokine Storm?

Coronavirus disease 2019 (COVID-19) induces a dysregulated immune response, leading to a drastic elevation of proinflammatory cytokines. This cytokine storm has the potential to aggravate any prior ongoing inflammation. Moreover, acute pancreatitis can cause local necrosis, thereby causing extensive abdominal inflammation. This condition increases the risk of abdominal compartment syndrome (ACS) and its deleterious consequences. We report the case of a 37-year-old male with a past medical history of chronic pancreatitis and alcohol use disorder who presented to the emergency department complaining of abdominal pain. Physical examination revealed a tender abdomen. Initial workup showed elevated amylase and lipase, a positive COVID-19 polymerase chain reaction (PCR) test, and elevated inflammatory markers. The patient denied any respiratory symptoms. Initial abdominal CT scan revealed mild pancreatic inflammation. The patient was admitted to the respiratory ICU and managed with fluid resuscitation and pain control. However, the patient had increasing oxygen requirements, leukocytosis, and worsening kidney function. A trans-bladder measurement of intra-abdominal pressure revealed severe ACS. Broad-spectrum antibiotics were started; however, after 72 hours of treatment, the patient had a cardiopulmonary arrest. He returned to spontaneous circulation after advanced cardiovascular life support (ACLS) protocol and intubation. A repeat CT scan of the abdomen showed necrotizing pancreatitis with a large-volume hemoperitoneum. Urgent pancreatic necrosectomy was performed with drainage of the hemoperitoneum. The patient was transferred to a long-term acute care facility for extended antibiotic therapy where he eventually recovered. This case illustrates the catastrophic consequences of necrotizing pancreatitis complicated by sepsis and ACS in a COVID-19-positive patient.

Guillain-Barre Syndrome in a Patient With COVID-19 Infection

Since the identification of SARS-CoV-2 or COVID-19 in Wuhan, several case reports have proposed a possible association between Guillain-Barre syndrome (GBS) and COVID-19. We describe a case of a 59-year-old female who initially presented with shortness of breath, tested positive for COVID-19, and subsequently developed acute hypoxic respiratory failure requiring mechanical ventilation. Her recovery was complicated by acute polyneuropathy. Clinical exam and lumbar puncture showing an albuminocytologic dissociation were consistent with GBS. The prevalence and association of GBS following COVID-19 infection require further research to understand the short and long-term neurological effects of COVID-19, as well as the management of these various neurological manifestations.

Comparison of Colorectal Cancer Surgery Services During COVID-19 First Wave With Pre-COVID Time

Introduction The first confirmed case of COVID-19 in the United Kingdom (UK) was reported on 29 January 2020. The country saw the peak of infection between March and May of 2020. The result was a change in the practice of how we treat most surgical conditions including cancer. We continued providing service to our colorectal cancer patients at a District General Hospital. The aim of this study was to compare our provision of colorectal cancer service during the peak of the pandemic to that of the pre-COVID time in our hospital.  Methods We collected data of all colorectal cancer patients who underwent surgery between 1 March 2020 and 30 April 2020 in our hospital. The comparative data were collected for similar patients during the same time frame in 2019. A detailed data set was compiled on Microsoft Excel (Microsoft Corp, Washington) and analysed using IBM SPSS Statistics for Windows, Version 21.0 (Released 2012. IBM Corp, Armonk, NY). Results The two groups were comparable in demographics including age, BMI, gender, and Charlson comorbidity index. Time from decision- to-treat to surgery, post-operative HDU/ITU stay, and overall length of stay was shorter in the COVID group than the Pre-COVID group without any significant statistical difference. There was no statistically significant difference between the two groups in Calvien-Dindo complications grade 1 and 2. No mortality was reported due to direct or indirect consequences of COVID-19 infection. More open procedures were performed in our department during the first wave of COVID-19 in the UK compared to Pre-COVID time. Conclusions Despite the challenges we faced during the peak of the COVID-19 pandemic, we managed to provide standard care to our colorectal cancer patients with comparable post-operative surgical and oncological outcomes.

Success Rate of Wire Control-Assisted ERCP Sphincterotomy Versus Non-assisted ERCP Cannulation of Common Bile Duct in a Secondary Care Unit During the First COVID-19 Peak: A Retrospective Observational Study of 281 Patients

Background

The British Society of Gastroenterology (BSG) recommended that during the COVID-19 pandemic, endoscopy units perform endoscopic retrograde cholangiopancreatography (ERCP) for obstructive biliary pathologies in an emergency. We assessed the local performance of ERCP during the first wave of COVID-19 at our local endoscopy center, in particular the technique to common bile duct (CBD) cannulation.

Methodology

All ERCP procedures performed from January to June 2020 were retrospectively assessed and compared with procedures performed between January and June 2019 at the Royal Lancaster Infirmary. The indications for ERCP, success rate, and complications were studied separately. Correlation analysis was conducted using Spearman's rank correlation coefficient. The binary logistic regression model was used to compute the factors associated with successful ERCP. Significance was established when the two-sided P-value < 0.05. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software version 25 for Windows (SPSS Inc., Chicago, IL, USA, 2017).

Results

A total of 281 ERCP were included in this study, with 169 and 112 performed during the first six months of 2019 and 2020, respectively. A statistically significant (0.0087) higher proportion of cases with liver dysfunction presented for ERCP before the COVID-19 outbreak (152, 89.94%). All patients before COVID-19 underwent wire control-assisted ERCP, while 82 (73.21%) received assisted ERCP during the first wave (P < 0.001). There was no statistically significant difference (P = 0.10) in the number of patients who underwent sphincterotomy before and during the first wave of COVID-19, with 97 (57.39%) and 76 (67.85%), respectively. The success rate of ERCP before COVID-19 was relatively high, accounting for 146 (86.39%) patients in contrast to 87 (77.67%) patients during the first wave (P = 0.074). Sphincterotomy (β = 2.800, P = 0.028) and stent insertion (β = 0.852, P = 0.046) were statistically significant predictors of ERCP outcomes. There was no statistically significant impact of cholangitis on the success of ERCP (β = 1.672, P = 0.109).

Conclusion

The first wave of COVID-19 had a statistically proven negative impact on the expected standards of ERCP performance. Although the complication rate was significantly higher during the first wave case difficulty, the American Society of Anesthesia (ASA) status was not assessed on an individual basis. Both ASA status and case difficulty are now included in our endoscopy selection process. We recommend adding the complexity of cases and ASA to the local and national recording databases. This is a rare study on UK-based hospitals.

Syndrome of Inappropriate Antidiuretic Hormone Secretion-Induced Encephalopathy in a Patient With COVID-19

Various electrolyte imbalances have been documented in coronavirus disease 2019 (COVID-19) patients who progress to severe acute respiratory syndrome coronavirus-2 infection. Patients with co-morbidities like diabetes, hypertension, obesity, ischemic heart disease, chronic kidney disease, and chronic obstructive pulmonary disease are more vulnerable to developing complications in the form of electrolyte disturbance.

We report a case of acute severe hyponatremia in a middle-aged man who was admitted to the hospital with viral pneumonia due to a coronavirus-2 infection. A dramatic drop of plasma sodium was preceded by gastrointestinal symptoms and followed by encephalopathy. On clinical assessment his plasma sodium was found to be critically low, i.e. 105 mmol/L. His chest x-ray showed minimal pleural effusion.

The patient was managed in the ICU and his serum sodium was normalized gradually with partial but rapid correction of this severe hyponatremia with hypertonic sodium chloride and followed by fluid restriction.

Comparative Evaluation of Nasopharyngeal and Oropharyngeal Swab Based Rapid SARS-CoV-2 Antigen Detection and Real-Time RT-PCR for Diagnosis of COVID-19 in Tertiary Care Hospital

Purpose: To assess and compare the diagnostic accuracy of the GenBody COVID-19 Antigen kit (GenBody Inc., Cheonan, South Korea) available in the market with the gold standard reverse transcription-polymerase chain reaction (RT-PCR) assay to detect severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).

Methods: Nasopharyngeal and oropharyngeal swabs were collected from suspected coronavirus disease 2019 (COVID-19) patients and tested by RT-PCR and GenBody Rapid antigen kit. Performance characteristic of the antigen kit was calculated.

Results: We tested nasopharyngeal swabs and oropharyngeal swabs (n=240). Amongst the 102 positive RT-PCR samples, the rapid antigen test detected 36 as positive, showing an overall sensitivity of 35.3%. All the samples detected positive with the antigen rapid test were also detected positive by RT-PCR.

Conclusion: The performance of the rapid antigen kit was good with respect to high viral load samples, whereas those with lower levels were missed. Unfortunately, the overall low sensitivity of the antigen kit does not allow using it alone as the frontline testing kit for COVID-19 diagnosis.

Predictive Role of Haematological Determinants on Outcomes of Critically Ill COVID-19 Patients Admitted to Intensive Care Unit

Background: The mortality of patients admitted to the intensive care unit (ICU) with COVID-19 remains significantly high. Severe COVID-19 pneumonia is characterised by refractory hypoxemia with significant shunting due to a combination of alveolar damage, vascular vasoconstriction, and occlusion due to microthrombi. Similar pathological features are seen in extra-pulmonary organs. However, the influence of thrombotic markers on the risk of mechanical ventilation (MV) and the development of acute kidney injury (AKI) is not fully defined.

Methods: This was a cross-sectional evaluation of haemostatic and thrombotic markers of COVID-19 patients admitted to the ICU to determine their predictability for the development of thromboembolism and the need for non-invasive or invasive MV, development of AKI, and mortality.

Results: An extended coagulation profile was obtained in 71 SARS-CoV-2 positive patients admitted to the ICU. All patients had acute severe hypoxic respiratory failure and required non-invasive or invasive MV. There were increases in peak D-dimer (3.0 mg/L), factor VIII levels (255 IU/dL) vWF antigen (471 IU/dL) with low ADAMTS13 activity (54.7 IU/dL) compared to the reference ranges. Peak D-dimer was consistently raised in patients who developed AKI and required invasive MV. ADAMTS13/vWF/platelet axis was associated with disease severity, multi-organ dysfunction, and mortality.

Conclusions: Haematological abnormalities are a common feature of severe COVID-19 pneumonia. We found peak D-dimer and vWF-ADAMTS13-platelet axis are associated with increased ICU severity and outcome in severe COVID-19 patients admitted to ICU. Larger studies are needed to evaluate this more comprehensively.

The Designing, Testing, and Utility of a 3D-Printed Respirator: A Hospital's Journey Into Self-Sustainability During COVID-19

Objective The current global COVID-19 pandemic has disrupted supply chains and the production of essential goods and services. This includes personal protective equipment (PPE) kits, respirators, and other protective devices. Hence efforts were made to prototype and produce 3D-printed N95 respirators to fill the gap in supply. In addition, methods of sterilization were put into place for the respirators. As well as forming standard operating procedures. Methods With the use of vast open-source libraries and collaboration with engineers and doctors fighting the COVID-19 pandemic, respirator prototypes were produced with special consideration to the sizing to fit median facial sizes. Polymer plastics were mixed in various proportions to condition the respirator to be used by frontline workers in austere environments. Due to the shortage of medical-grade filter media, alternative sources were researched. Merv 13 and Merv 15 filters were selected due to their cheap costs, vast abundance, and proven filtration efficacy against particles of 0.03 microns. Studies conducted around the world have also shown its efficacy as an alternative to medical-grade air filter media. After developing standard operating procedures (SOPs) for sterilisation and respirator usage. Emergency approval was obtained and a limited number of healthcare workers were issued with this respirator (n=400). PPE kit satisfaction and self-efficacy scores were calculated from daily questionnaires during donning and doffing Results Qualitative fit-tests in all 400 healthcare workers matched those of a conventional N95 respirator. Almost all of the respondents in the PPE kit satisfaction responded positively. The self-efficacy score calculated from the general self-efficiency scale had an overall positive value, with the average score being 4.29. This demonstrated that the self-efficacy score was above average and indicated a high motivation to overcome obstacles and spend more time solving problems. The average self-efficacy score is defined between 2.5 - 3.5, and a low self-efficacy score is defined as a score below 2.5. Lastly, a regression analysis was done to test the correlation between PPE kit satisfaction and self-efficiency this demonstrated a positive correlation between PPE kit satisfaction using the 3D-printed respirator and self-efficacy (Slope: 0.416, Intercept: -1.066, R-value: 0.872, P-value: <0.01) Conclusions With supply chain disruptions and reduced or nonexistent supplies of essential medical goods. The need of a reusable, sterilisable, and efficient respirator has never been more evident. The materials used have made it sustain heavy use in austere environments. Studies have reported higher than average burnout rates in COVID-19-based healthcare workers. Studies have also shown that the rates of burnout are high in healthcare professionals without access to proper PPE kits in developing nations. This respirator was rated highly in PPE kit satisfaction and the self-efficacy score. Studies have demonstrated a correlation between high self-efficacy scores and low burnout rates in health care workers. There is also documented evidence of a positive correlation between high self-efficacy scores and general health. As the pandemic continues to evolve, so will the efforts to combat it, such as 3D printing. Interdisciplinary collaboration continues to drive our efforts to combat the pandemic and hopefully resolve it in the future.

Negative Impact of COVID-19 Upon Primary Brain Tumor Care

Meningiomas are the most common primary central nervous system tumors, as they can account for up to one-third of all primary brain tumors. Most meningiomas are benign, although up to one-fourth of such tumors are classified as atypical or malignant. Atypical and malignant meningiomas are associated with an increased risk of local recurrence and decreased overall survival. Our patient is a 57-year-old male with a history of recurrent malignant meningioma, with metastasis to the liver. He underwent multiple surgical interventions, radiation treatments, and systemic therapies for a malignant meningioma, ultimately requiring transfer to hospice care. Not only did a positive novel coronavirus (COVID-19) infection delay his ability to receive radiation therapy, the infection in itself may have had an impact on the course of care for this patient. Treatment targeting the patient's COVID-19 infection may have suppressed the immune system, and as a result, caused the progression of metastatic disease. Palliative care was needed in the setting of losing all functional goals for quality of life due to malignant neoplasm.

Rapid Expansion of the Airway Response Team to Meet the Needs of the COVID-19 Pandemic

INTRODUCTION

The COVID-19 pandemic has brought unprecedented numbers of patients with acute respiratory distress to medical centers. Hospital systems require rapid adaptation to respond to the increased demand for airway management while ensuring high quality patient care and provider safety. There is limited literature detailing successful system-level approaches to adapt to the surge of COVID-19 patients requiring airway management.

METHODS

A deliberate system-level approach was used to expand a preexisting airway response service. Through a needs analysis (taking into account both existing resources and anticipated demands), we established priorities and solutions for the airway management challenges encountered during the pandemic.

RESULTS

During our COVID-19 surge (March 10, 2020, through May 26, 2020), there were 619 airway consults, and the COVID airway response team (CART) performed 341 intubations. Despite a 4-fold increase in intubations during the surge, there was no increase in cardiac arrests or surgical airways and no documented COVID-19 infections among the CART.

CONCLUSIONS

Our system-level approach successfully met the sudden escalation in demand in airway management incurred by the COVID-19 surge. The approach that addressed staffing needs prioritized provider protection and enhanced quality and safety monitoring may be adaptable to other institutions.

COVID-19-Associated Pneumomediastinum: An Emerging Clinical Presentation

Recent publications have suggested an association between coronavirus disease 2019 (COVID-19) pneumonitis and pneumomediastinum. The association has been linked to the frequent use of mechanical ventilation in these patients; however, there have also been increasing reports of spontaneous pneumomediastinum in the absence of mechanical ventilation. These reports suggest a direct association between COVID-19 pneumonitis and increased alveolar fragility. In this report, we present a case of a spontaneous mediastinum in a 64-year-old male patient with COVID-19 without any history of mechanical ventilation.

Encephalopathy in COVID-19 Patients

The clinical presentation of coronavirus disease 2019 (COVID-19) has a wide spectrum, ranging from asymptomatic patients to severe presentations with acute respiratory distress syndrome (ARDS), kidney injury, stroke, electrolyte imbalance, and multi-organ failure. Encephalopathy and encephalitis are devastating severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) virus‐associated central nervous system complications.

We reported a case of a 67-year-old male who was admitted to the hospital for the management of COVID-19 pneumonia. Due to worsening hypoxia, the patient was transferred to ICU and was intubated. On examination, he was aphasic and noted to have right-sided hemiplegia with left-sided hemiparesis on day 4. CT scan of the head without contrast and MRI findings were suggestive of acute necrotizing encephalopathy secondary to intracranial cytokine storm caused by viral infection. The patient was treated with intravenous immunoglobulin (IVIG), and high dose corticosteroids, with clinical improvement in the right-sided hemiparesis on day 5. A repeat MRI brain revealed decreased edema.

The pathogenesis of encephalopathy associated with COVID-19 may be multifactorial. Postulated mechanisms include hypoxic/metabolic changes produced by the intense inflammatory response due to cytokine storm and neurotropism. Cytokine storm causes hypoxia and metabolic insults that result in global dysfunction of the brain. Altered consciousness, ranging from mild confusion, delirium, to deep coma, are some of the cardinal clinical features. The most common imaging finding on MRI T2-weighted fluid-attenuated inversion recovery (MRI T2/FLAIR) includes symmetric, multifocal lesions with invariable thalamic involvement. Other commonly involved locations include the brainstem, cerebral white matter, cortical and subcortical white matter, and cerebellum. In a few case reports, cerebrospinal fluid (CSF) analysis has shown the presence of the virus. Management of encephalopathy in COVID-19 patients involves supportive care including supplemental oxygen therapy and immune modulators. Immune modulation therapy including high-dose corticosteroids and IVIG have been shown to improve outcomes in these patients.

SARS-CoV-2 Vaccination-Induced Transverse Myelitis

While mass immunization against coronavirus disease 2019 (COVID-19) rolls out around the globe, safety concerns and adverse events that need prompt evaluation are also emerging. We report a case of transverse myelitis and Bell's palsy after receiving Johnson and Johnson COVID-19 vaccination under the emergency use authorization in a healthy young woman with no past medical history. Other possible etiologies of her symptoms were ruled out, and she was treated successfully with steroids and plasma exchange.

A Case of Fatal Catatonia in a COVID-19 Patient

COVID-19 has been associated with numerous complications, primarily pulmonary in origin. However, there have been several neurological sequelae of COVID-19 as well, one of the rarer complications is catatonia. In this already vulnerable population, it is imperative for the early diagnosis of catatonia and starting treatment. Delay in treatment of catatonia can be fatal from secondary complications as seen here. We discuss a case of a 62-year-old female that presented with mild COVID pneumonia, subsequently developed catatonia precipitated by COVID-19 encephalitis, which ultimately led to her death from complications.

Cerebral Venous Sinus Thrombosis as an Unexpected Complication of COVID-19 Pneumonia

Coronavirus disease 2019 (COVID-19) is commonly associated with acute respiratory distress syndrome and acute cardiac and renal injuries. However, thromboembolic events are also prevalent in COVID-19. The pathogenesis of COVID-19 hypercoagulability is not well known but may be linked to the cytokine storm induced by a viral infection or endothelial damage that triggers a cascade leading to hypercoagulability. Because vascular endothelium has angiotensin-converting enzyme 2-like lung tissue, COVID-19 targets lung tissue and vascular endothelium, leading to thrombosis. We present a rare case of a young patient with COVID-19 who presented with thrombosis of the cerebral venous system managed with anticoagulation. This case highlights the need for heightened awareness of this atypical but potentially treatable complication of the COVID-19 disease spectrum.

Retrospective Analysis of COVID-19 Conversion Rate Among Anesthesiologists in Acute Care Centers

Brief description of the primary research objective

Among healthcare workers, anesthesiologists are regarded as frequently exposed frontline providers in the fight against COVID-19 due to their proximity to patient airways and involvement in aerosolized procedures. As such, the risk of contracting the COVID-19 virus as an occupational hazard is presumed to be higher. To date, in most published studies, all healthcare workers were grouped together, independent of specialty or profession. At the time that this survey was distributed, we did not find any peer-reviewed articles that differentiated COVID-19 infection rates among frontline, such as anesthesiologists vs. non-frontline healthcare workers. This retrospective survey’s primary research objective was to report the rate of COVID-19 infection among anesthesiologists compared to the general population of healthcare workers.

Methodology

A survey was sent among anesthesiology attendings and residents in Northern New Jersey and Brooklyn, New York hospitals on duty during the peak pandemic from March 2020 to May 2020. Questions in the survey focused on infection rates and adherence to standards of infection precaution and personal protective equipment (PPE) utilization.

Main Findings

This retrospective study highlights the rate of infection among anesthesiologists as a particularly vulnerable subgroup of frontline residents and physicians, as they are called to duty when emergent airway management is required. In our study, the reported rate of contracting COVID-19 among anesthesiologists was 16.7%. This statistic is higher than the infection rates published by studies by New York State and the CDC.

Conclusion

The survey sent to anesthesiologists is useful to understand the impact of COVID-19 on this subgroup of frontline providers and the importance of adhering to standards of infection protocol and the role of PPE.

Post Severe Acute Respiratory Syndrome Coronavirus 2 Infection Tremors in a Nonverbal Autistic Adolescent

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19) pandemic in 2020 remains a major public health challenge until mass vaccination. The number of SARS-CoV-2 positive children aged 0-17 years has been increasing as older adults are vaccinated. Infected children tend to have less severe illness compared with adults, have predominantly respiratory or GI symptoms, or no symptoms. Children have an increased risk for multisystem inflammatory syndrome in children (MIS-C), which is unique. Neuropsychological complications of COVID-19 remain uncommon. Case reports and data from series exist. We report a case of tremors as sequelae of SARS-CoV-2 infection in a non-verbal adolescent with autism spectrum disorder (ASD).

Third-Degree Heart Block Associated With Saddle Pulmonary Embolism: A Rare Sequelae of COVID-19-Induced Hypercoagulable State

The pathophysiology of coronavirus disease 2019 (COVID-19) involves multi-organ dysfunction, particularly involving the respiratory, cardiovascular and hematological systems. This dysfunction is partly due to systemic inflammation causing a wide array of pathological sequelae thus posing a significant challenge to management despite the advances in treatment made thus far. In this report, we present a COVID-19 patient who developed a transient complete heart block and was temporarily paced as a complication of a saddle pulmonary embolus (PE). The mechanism of complete heart block is unclear, may be related to strain, ischemia, or vagal response. We believe that this is a unique sequence of events in a COVID-19 patient and, to our knowledge, is the first of its kind to be reported.

COVID-19 Vaccine Hesitancy in Healthcare Workers Amidst the Second Wave of the Pandemic in India: A Single Centre Study

Introduction Coronavirus disease 2019 (COVID-19) vaccine hesitancy amongst healthcare workers (HCW) has been reported in varying degrees in different parts of the world. In this study, we investigate the degree of vaccine hesitancy amongst HCWs and factors associated with it during the second wave of the pandemic in our centre. Methods We undertook this single-centre, cross-sectional study in an urban tertiary care hospital, using a modified Oxford COVID-19 vaccine hesitancy scale. We performed descriptive and appropriate univariate analysis. We used the Kruskal Wallis test as appropriate, and Spearman rank correlation to evaluate the relation between general attitude to vaccination and COVID vaccine hesitancy score. Results We obtained 223 responses. The majority of HCWs in our sample (n = 201; 90.1%) had received at least one dose of the vaccine. The mean (SD) Oxford vaccine hesitancy score was 28.54 ± 2.05, with no significant difference observed between doctors (28.45 ± 2.26) and nurses (28.68 ± 1.70), or across different specialities. Of the respondents, 92.7% (n = 216) responded positively to taking the vaccine. The lack of dependents at home was the only significant contributor to vaccine hesitancy. Age, gender, marital status, and COVID-19 infection status did not significantly affect vaccine hesitancy. Conclusion We found a significantly lower degree of hesitancy towards COVID-19 amongst HCWs in our centre during the pandemic's second wave. A more comprehensive and multi-centric study is required to validate this finding.

Emerging Needs and Viability of Telepsychiatry During and Post COVID-19 Era: A Literature Review

The coronavirus disease 2019 (COVID-19) pandemic has resulted in nationwide stay-at-home orders in an effort to slow the spread severely impacting the healthcare sector. Telepsychiatry provides a platform bridging the gap through advanced technologies connecting mental health providers and patients who need their services, overcoming previous barriers of great distances, lack of transportation, and even time constraints. The most obvious benefit is increased accessibility to mental healthcare, especially in underserved and remote areas where there is no easy access for in-person care. It is important to note that benefits are not limited to patients, but also allow clinicians greater flexibility in scheduling and reduced practice overhead costs, both of which aid with physician burnout and burden. Telepsychiatry during COVID-19 provides its own unique advantages over in-person visits. The risk of exposure to healthcare workers and patients receiving care is reduced, allowing immunocompromised patients to receive much-needed psychiatric care. Without the need to meet in person, self-isolating psychiatrists can still provide care, decreasing strain on their co-workers. Although telepsychiatry is relatively new, it has already exhibited considerable success in its effectiveness at treating psychiatric conditions and widespread corollary benefits. Telepsychiatric consults may be carried out synchronously and asynchronously, each having benefits and setbacks. Different mobile application interventions have been explored, which are available for the purpose of both monitoring/assessing patients and/or providing treatment. The scope of conditions these applications address is broad, from anxiety disorders to schizophrenia to depression. As promising and beneficial telepsychiatry may seem, it is necessary to recognize that building the program can be challenging. It involves adapting to new methods in medicine. We highlighted barriers to general telepsychiatry, the most prominent being technological literacy of both physician and patient, and possible negative effects of eliminating the in-person patient-doctor interaction.

Cardiogenic Shock Due to Multisystem Inflammatory Syndrome in a Young Adult Female

Multisystem inflammatory syndrome in adults (MIS-A) was initially described by pediatricians after reporting a temporal association of a mimicker of Kawasaki disease shortly after the resolution of a COVID-19 illness. Since June 2020, there have been an increased amount of reports of adults and adolescents above the age of 18 presenting with the syndrome. We report a case of a 20-year-old female with no medical history who presented with cardiogenic shock and was found to have MIS-A. 

A Unique Case of Acute Coronary Syndrome in a Patient With COVID-19 Infection

The coronavirus pandemic has caused significant mortality and morbidity in just over a year of its course since the first case was identified in Wuhan, China in December 2019. The varied presenting symptoms of this enveloped positive-sense single-stranded RNA virus infection and the unknown surrounding the pathophysiology of the disease process have been extensively reported in the literature. In this case report, we present a coronavirus disease 2019 (COVID-19) positive patient who presented with chest pain, diagnosed with acute coronary syndrome. Interestingly, the patient was noted to have non-ST elevation myocardial infarction with cardiac catheterization showing coronary microthrombi rather than typical acute coronary thrombotic occlusive disease.

The patent maze of COVID 19 vaccines

Introduction: NGOs and governments of some countries have demanded suspension of patents protection of COVID-19 vaccines and the underlying technology to enhance worldwide access. At the same time, companies actually developing and producing COVID-19 vaccines have to navigate the patent landscape and have to deal with 3rd party patents.Areas covered: This article discusses these different aspects regarding patent protection of COVID-19 vaccines. Patent searches have been carried out in Espacenet and the ORBIT database. Different search strings were used by the author, based on his own background knowledge.Expert opinion: SARS-CoV 2 was for the first time fully described on 10 January 2020, so it is so far not possible to determine if, and by whom, patent applications were filed for respective vaccines. On that background, allegations that patents would be responsible for insufficient access to the vaccine in particular in developing countries are baseless. Even the key players are facing contraints caused by third-party patents, and legal disputes are already ongoing. Anyway, the bigger obstacle for worldwide equitable vaccine distribution seems to reside in know how transfer and production capacities, as ramping up production requires considerable efforts.

Assessment of Burnout Levels before and during COVID-19 Pandemic: A Web-Based Survey by the (Italian) Association of Medical Endocrinologists (AME)

BACKGROUND

Some endocrinologists were involved in the management of patients with suspected or confirmed COVID-19 during the first wave of the pandemic. This study aims to analyze burnout levels among the Association of Medical Endocrinologists (AME) members before and during the pandemic.

METHODS

We recruited two AME members samples at two different times: before COVID-19 (n = 811) and during the first wave of the ongoing pandemic (n = 579). Both the samples filled the Maslach Burnout Inventory. We performed MANOVAs to evaluate demographic and COVID-19 related differences in burnout levels and Pearson's Chi-square test to compare burnout severity before and during the pandemic.

RESULTS

Women reported higher Emotional Exhaustion and reduced Professional Accomplishment than men. The oldest physicians had lower levels of Emotional Exhaustion and Depersonalization and higher Professional Accomplishment than younger workers. Independent contractors displayed lower levels of burnout compared to established contractors. Finally, the pandemic, per se, did not lead to changes in burnout levels.

DISCUSSION

Women and young physicians are at higher risk of burnout. It is also possible that front-line professionals are at higher risk during a health care crisis. Moreover, it is likely that the length of exposure to the pandemic has not been sufficient to impact burnout levels.

CONCLUSIONS

Short-term exposure to pandemic-related activities seemed to have a low impact on burnout severity, except for physicians directly involved in managing COVID-19 cases. It is strongly recommended the availability of psychological support in public hospitals.

Cross neutralization of emerging SARS-CoV-2 variants of concern by antibodies targeting distinct epitopes on spike

Several severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants have arisen that exhibit increased viral transmissibility and partial evasion of immunity induced by natural infection and vaccination. To address the specific antibody targets that were affected by recent viral variants, we generated 43 monoclonal antibodies (mAbs) from 10 convalescent donors that bound three distinct domains of the SARS-CoV-2 spike. Viral variants harboring mutations at K417, E484 and N501 could escape most of the highly potent antibodies against the receptor binding domain (RBD). Despite this, we identified 12 neutralizing mAbs against three distinct regions of the spike protein that neutralize SARS-CoV-2 and the variants of concern, including B.1.1.7 (alpha), P.1 (gamma) and B.1.617.2 (delta). Notably, antibodies targeting distinct epitopes could neutralize discrete variants, suggesting different variants may have evolved to disrupt the binding of particular neutralizing antibody classes. These results underscore that humans exposed to wildtype (WT) SARS-CoV-2 do possess neutralizing antibodies against current variants and that it is critical to induce antibodies targeting multiple distinct epitopes of the spike that can neutralize emerging variants of concern.

Subacute Thyroiditis After Receiving the Adenovirus-Vectored Vaccine for Coronavirus Disease (COVID-19)

Since the emergence of the coronavirus disease pandemic, several effective vaccines have been introduced. These vaccines work through several different immunogenic pathways to produce effective immunity. There have been a number of reports of patients developing subacute thyroiditis and thyroid dysfunction after receiving the coronavirus (COVID-19) vaccine. This paper presents a case of a female patient who developed subacute thyroiditis soon after receiving the adenovirus-vectored COVID-19 vaccine. The patient presented with severe neck pain and her blood results demonstrated an initial thyrotoxic phase followed by a hypothyroid phase. She had no past history of thyroiditis or thyroid dysfunction. Subacute thyroiditis occurring after COVID-19 vaccination is rare but also probably underreported. We hope that this case report not only contributes to the literature but also raises awareness of subacute thyroiditis occurring after receiving the COVID-19 vaccine.

Aortic Thrombosis and Acute Limb Ischemia Secondary to COVID Hypercoagulability

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19), first identified in December 2019 in Wuhan, China, has rapidly spread worldwide, is now a public health emergency, and has been declared a pandemic. While SARS-CoV-2 is known to cause significant pulmonary disease, ranging from pneumonia to acute respiratory distress syndrome (ARDS), various extrapulmonary manifestations of COVID-19 have also been reported. Growing evidence suggests that COVID-19 leads to a hypercoagulable state leading to micro and macro-vascular angiopathies. We present a case of an 80-year-old male without a previous history of prothrombotic disorders who developed descending aortic thrombosis, approximately 40% stenosis, at the level of the diaphragmatic hiatus and acute limb ischemia secondary to COVID-19 requiring emergent surgical intervention. After 12 days of persistent ischemic left lower extremity imaging despite thrombectomy, bypass, and therapeutic heparin, the patient's limb was deemed non-salvageable and underwent left above-knee amputation. Transthoracic echocardiogram revealed normal left ventricular function, moderate pulmonary hypertension, and no evidence of atrial septal defect, aortic root abnormalities, or intraventricular thrombi. Evaluation of autoimmune and inflammatory vasculitis was negative. While further study into the prothrombotic nature of this condition still needs to be pursued, the thromboembolic risk of COVID-19 represents an urgent need for appropriate anticoagulation for venous thrombosis. Arterial thrombosis requires other kinds of management to avoid the severe adverse effects of emboli and related ischemia. This current case highlights the need for randomized control trials testing different prophylactic strategies. Further evidence is also required for the role of amputation surgery when initial interventions for revascularization fail to restore blood flow.

Fulminant Myocarditis With ST Elevation and Cardiogenic Shock in a SARS-CoV-2 Patient

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first described in patients in Wuhan, China, who presented with flu-like symptoms. Since then, it has spread all over the world and in March 2020 it was labeled as a pandemic by the World Health Organization. Most common presentations include respiratory symptoms that vary from mild cough and shortness of breath to severe acute respiratory distress syndrome. Gastrointestinal symptoms like nausea, vomiting and diarrhea are also common. However, cardiovascular complications have not been reported widely. Patients can present with cardiac complications that include chest pain, heart failure and fulminant myocarditis, which is one of the most serious cardiac manifestations. Primary means of diagnosis are echocardiogram and cardiac magnetic imaging. Treatment is mostly supportive in case of cardiogenic shock and includes ionotropic support with or without mechanical circulatory support and mechanical ventilation. A strong suspicion is required for early diagnosis and aggressive treatment in order to reduce mortality and morbidity.

Epidemiological Study of COVID-19 Fatalities and Vaccine Uptake: Insight From a Public Health Database in Ontario, Canada

Coronavirus disease (COVID-19) has reached millions of people worldwide and is responsible for millions of deaths around the world. Research on fatalities in rural communities remains limited. In addition, the scientific literature has not yet reported on the distribution of vaccines in Canada and compared the findings to the age distribution of COVID-19 fatalities in Canada to see whether the vaccines have been distributed to the highest age category populations. This research article used data from the Government of Ontario and Statistics Canada to analyze the number of cases, fatalities, case fatality rates (CFRs) by demographic factors, such as age, gender, urban-rural status, and compared the findings to national vaccination rates by age. As of June 11, 2021, this study found that among the 528,819 cases among 14.8 million people. Among this population, there were 8875 fatalities in Ontario with 82.208% (n=7296) of fatalities occurred in people over 70 years, and 93.183% in people over 60 years (n=8,270). Additionally, the odds ratio of a fatal event was 9,652 times higher in people over 90 years (95% CI: 4418, 31124, p<0.001) as compared with less than 20 years. Men had a higher number of fatalities (n=4,490, CFR=1.721%) compared with women (n=4,385, CFR=1.692%), and a higher odd of fatal events only when adjusted for age and gender (OR=1.66, 95% CI: 1.57, 1.74, p<0.001). Urban areas had 92.034% of fatalities (n=8,168) and had a CFR of 1.632%. In contrast, rural areas comprised 4.451% of total fatalities (n=395) and had the highest CFR (2.267%). The unadjusted odds of a fatality were 1.41 (95% CI: 1.27, 1.56) in rural areas compared with urban areas. Across Canada as of May 29, 2021, people over 80 years old received 1,530,318 vaccines with 91.98% of this population age group receiving at least one and 457,664 being fully vaccinated (27.51%). In Ontario, as the number of people with at least one vaccine increased for people over 90 years, the number of fatalities was reduced from about 8 per day prior to vaccines to approximately two per day. Furthermore, once the vaccination rates exceeded 75% in ages 60 years and over 50% in the younger age groups, the number of fatalities per day among all age groups was approximately one per day. In summary, age was found to be a significant factor for COVID-19 mortality in Ontario and vaccine uptake in Ontario was followed by decreases in COVID-19 mortality.
