Reactivation of Parvovirus B19 Infection: An Uncommon Trigger of Macrophage Activation Syndrome in Adult-Onset Still's Disease.

A 40-year-old woman presented with four weeks of intermittent high-grade fever, cough, and joint pain, and two weeks of a generalized rash. She was found to have adult-onset Still's disease (AOSD) and rapidly developed macrophage activation syndrome (MAS) on the second day of admission. Among infectious etiologies, Epstein-Barr virus and members of the herpes virus family are common triggers of MAS. However, our patient was found to have reactivation/recurrence of parvovirus B19 infection as the cause; this is an uncommon trigger reported infrequently in the medical literature. Despite intensive treatment, the patient passed away.

When should clinicians use the term syndrome?

Medical language provides essential communication with patients and among healthcare providers. Some words appear frequently in this communication, in clinical records, and in the medical literature, and the use of these words assumes that the listener and reader understand their meaning in the context related to their current use. Words, such as syndrome, disorder, and disease, should have obvious definitions but often, in fact, have uncertain meanings. In particular, the word syndrome should imply a definite and stable association between patient characteristics that have implications for treatment, prognosis, pathogenesis, and possibly clinical studies. In many cases the strength of this association is uncertain and the use of the word represents a convenient shorthand which may or may not improve communication with patients or other clinicians. Some astute clinicians have identified associations in their clinical practices, but this is a slow haphazard process. The development of electronic medical records, internet-based communication, and advanced statistical techniques has the potential to clarify important features of syndromes. However, the recent analysis of certain subsets of patients in the ongoing COVID-19 pandemic has demonstrated that even large amounts of information and advanced statistical techniques using clustering or machine learning may not provide precise separation of patients into groups. Clinicians should use the word syndrome carefully.

COVID toes following vaccination.

Cutaneous manifestations of COVID-19 infections include "COVID toes." These are pernio-like, pale purple, painful, ill-defined cyanotic lesions that have inflammatory infiltrates on histologic studies. COVID toes can also develop following COVID vaccination. COVID toes was reported by 29 individuals to the Vaccine Adverse Event Reporting System maintained by the Centers for Disease Control and Prevention through May 25, 2021. The mean age of these individuals was 52 ± 18 years; 23 (79%) were women. They had received both mRNA vaccines and the adenovirus vector-based vaccine. This discoloration developed 4.5 ± 9.8 days following vaccination, usually after the first dose. Four individuals required hospitalization for systemic symptoms, and one died. This information indicates that some individuals develop important clinical syndromes following vaccination and suggests that some of the manifestations of COVID-19 infection represent immune responses and not necessarily active tissue infection.

COVID-19 Vaccination Attitude and Behavior among Nurses at a West Texas Regional Hospital.

Vaccinations against COVID-19 infection have become a contentious issue in the United States. Multiple segments of society, including healthcare workers, have expressed concerns regarding the need for vaccination and the safety of current vaccines. Many hospital-based nurses have helped care for patients with severe COVID-19 infections. An anonymous online survey was sent to the nursing staff at University Medical Center in Lubbock, TX, USA, through a hospital-based email system to determine vaccination status and attitudes towards the COVID-19 vaccine and other routine vaccines. Multivariable regression analysis was used to determine factors associated with vaccination. A total of 251 nurses responded to this survey; 211 nurses (83.7%) had received the vaccine. Almost all nurses (242, 96%) had received all childhood vaccinations, and 231 (91.7%) had received an influenza vaccination in the prior year. A minority of nurses (75, 29.8%) supported mandatory vaccination for healthcare workers. The reasons for declining vaccination included the possibility that diet and alternative medications provided better protection against COVID-19. This survey demonstrates that over 80% of nurses working in a hospital managing very sick patients with COVID-19 infection had been vaccinated. However, nurses who did not take the annual influenza vaccine and did not consider other protective measures useful (such as mask-wearing) were significantly less likely to vaccinate. Nurses can provide an important resource for conversations with the public and patients about vaccine initiatives.

Clinical Characteristics of Hospital Follow-up for Patients Hospitalized from SARS CoV-2 (COVID 19) in an Academic Outpatient Internal Medicine Clinic.

BACKGROUND: As of July 2022, there have been more than 91.3 million cases of COVID-19 and nearly 1.03 million deaths in the United States alone. In addition, many people who survived COVID-19 had long-term symptoms, such as fatigue, dyspnea, loss of smell and taste, depression, and anxiety. OBJECTIVES: The purpose of our study is to evaluate the status of COVID-19 patients who were previously hospitalized. METHODS: We conducted a single-center retrospective cohort study at Texas Tech University Health Sciences Center and its affiliated University Medical Center under IRB of L21-144. We included all patients hospitalized for COVID-19 and followed up in our Internal Medicine Clinic at any time between April 1, 2020, and April 1, 2021, and reviewed follow-up data for these patients after discharge. RESULTS: A total of 128 patients were included; 59 (46%) were men, and 69 (54%) were women with an average age of 59.7 ± 14.8 years. Most of the patients (n = 78, 60.9%) identified their race as Hispanic or Latino origin; the next largest group was Caucasian (n = 29, 22.65%). The average number of days until post-hospitalization follow-up was 36 ± 38 days. The 50% of the patients (n = 64) used telemedicine for follow-up visits. Important comorbidities in these patients included diabetes (n = 84, 65.6%) and hypertension (n = 94, 73.4%). Thirty-four patients (26.6%) reported respiratory symptoms at their follow-up appointments, 24 patients (18.8%) reported constitutional symptoms, 12 patients (9.4%) reported GI symptoms, and 25 patients (19.5%) reported other symptoms, such as paresthesia, lower extremity edema, or psychological symptoms. After hospital discharge, 54 patients had follow-up chest x-rays, and 41 (75.9%) still had abnormal findings consistent with COVID-19 imaging characteristics. Follow-up laboratory tests identified 44 patients (77.2%, 57 tested) with elevated D-dimer levels, 44 patients (78.6%, 56 tested) with high ferritin levels, and 21patients (35.6%, 59 tested) with elevated troponin T HS levels. CONCLUSION: Long-lasting COVID-19 symptoms in these patients included respiratory symptoms (26.6%), constitutional symptoms (18.8%), GI symptoms (9.4%), and other symptoms, such as paresthesia, lower extremity edema, or psychological symptoms (19.5%). The rate of telehealth follow-up was 50%. Many patients had elevated inflammatory markers that will need follow up to determine the clinical implications.

Multisystem inflammatory syndrome following COVID-19 vaccination.

Multiple extrapulmonary symptoms have been described in individuals with elevated inflammatory markers after COVID infection, which have been grouped and classified as a new inflammatory syndrome, called multisystem inflammatory syndrome in adults (MIS-A). However, little is known about MIS-A, including its prevalence, predisposing conditions, or patient outcomes. We report a case of severe postvaccination symptoms that occurred after administration of the Moderna vaccine in an individual with no prior history of COVID infection. We also review a case series that fulfills the criteria for MIS-A reported in the literature and summarize the characteristics of patients developing MIS-A after COVID-19 vaccination.

Spontaneous large liver haematoma with extensive intraperitoneal bleeding in a patient with COVID-19 infection.

Thrombotic complications during COVID-19 infections occur frequently, and anticoagulants to prevent and treat deep vein thrombosis appear to have a good safety profile in these patients. In addition, haemorrhagic complications during COVID-19 infections have also been reported. Hepatic inflammation can occur in COVID-19 infections as a direct consequence of cellular infection and cytopathy. Spontaneous subcapsular hepatic haematoma is extremely rare and can be life-threatening.A woman in her 40s presented to the hospital with fever and shortness of breath and was diagnosed with COVID-19 infection with respiratory failure requiring intubation. On day 49 of hospitalisation, she developed melena and acute anaemia; her haemoglobin dropped from 97g/L (9.7g/dL) to 56g/L (5.6g/dL). Abdominal and pelvic CT scans showed a large subcapsular liver haematoma with retroperitoneal extension. The patient received blood transfusions and remained haemodynamically stable. She was eventually extubated and discharged home.

COVID-19 Vaccination Hesitancy among Healthcare Workers-A Review.

The COVID-19 pandemic and its associated vaccine have highlighted vaccine hesitancy among healthcare workers (HCWs). Vaccine hesitancy among this group existed prior to the pandemic and particularly centered around influenza vaccination. Being a physician, having more advanced education, and previous vaccination habits are frequently associated with vaccine acceptance. The relationship between age and caring for patients on COVID-19 vaccination is unclear, with studies providing opposing results. Reasons for hesitancy include concerns about safety and efficacy, mistrust of government and institutions, waiting for more data, and feeling that personal rights are being infringed upon. Many of these reasons reflect previous attitudes about influenza vaccination as well as political beliefs and views of personal autonomy. Finally, several interventions to encourage vaccination have been studied, including education programs and non-monetary incentives with the most effective studies using a combination of methods.

Continued Visibility of COVID-19 Article Removals.

OBJECTIVE: The coronavirus disease 2019 pandemic has produced an unprecedented amount of scientific research as well as a high number of article retractions. Social and news media have been used to disseminate scientific research, and this can include retracted or withdrawn research. This risks the persistence of low-quality research and may contribute to controversial ideas or conspiracy theories. METHODS: We examined 34 retracted or withdrawn coronavirus disease 2019 articles using alternative metrics. RESULTS: These articles continued to receive social and news media mentions up to 180 days postremoval, although most mentions occurred within 30 days postremoval. Articles available on preprint servers accounted for 45.5% of total mentions. CONCLUSIONS: A significant, positive correlation was observed among Scimago Journal Rank, Immediacy Index, and Journal Citation Index, and total article mentions.

ST-Elevation Myocardial Infarction as a Late Complication of Mild Coronavirus Disease 2019 Infection: A Case Report.

Endothelial dysfunction with subsequent thrombosis and, less commonly, vasculitis has been implicated during the active phase of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection. However, less has been described during the recovery phase or as late sequelae. Here, we report a case of acute anterior wall ST-elevation myocardial infarction in a female patient with no medical history of cardiovascular risk factors as a post-infectious complication of coronavirus disease 2019 (COVID-19). Coronary angiography revealed total occlusion of her left anterior descending, right coronary arteries, and tight stenosis in the left circumflex artery. Successful revascularization with a staged percutaneous coronary intervention was achieved. To date, there is not much data regarding the late cardiovascular sequelae of COVID-19 and its possible mechanisms. Prolonged follow-up, even for mild cases of COVID-19, is advised for early diagnosis and treatment of long-term complications of COVID-19.

The Gaisbock syndrome after COVID-19 pneumonia.

In 1905, Felix Gaisbock, MD, described a syndrome in patients with hypertension, elevated hematocrit levels, plethoric appearances, and no splenomegaly. He postulated this relative erythrocytosis was due to stress. In this case report, a 40-year-old Caucasian man with obesity was admitted with recurrent deep vein thrombosis and increasing oxygen requirements 2 weeks after hospitalization with COVID-19 pneumonia. This patient had a 10-year history of untreated hypertension and erythrocytosis. He had a ruddy appearance, a normal erythropoietin level, and a negative JAK2 V617 mutation. In this case, Gaisbock syndrome was suspected.

2019 Novel Coronavirus Vaccination Among Medical Students.

COIVD-19 vaccination of medical students is essential since these students will have contact with patients and will become future healthcare leaders. Hence, we surveyed medical students at Texas Tech University Health Science Center in Lubbock, TX, and received 234 responses. The majority of students were vaccinated against COVID-19 (215/234; 91.8%) and reported pro-vaccine attitudes, such as support for a COVID-19 booster shot (191/234; 81.6%) and an annual COVID-19 vaccine (186/234; 79.5%). Among those who did not receive the COVID-19 vaccine, the most frequent reasons included waiting for more evidence (16/19; 84.2%) and concern about the side effects (15/19; 79.0%). These results indicate that medical students consider vaccination important and suggest that students can provide an important resource for patients and public education.

Alternative publication metrics in the time of COVID-19.

Alternative metrics are unique bibliometrics comprising social, news, and other sources of media outside of traditional academic citations. Some have suggested that these metrics can complement traditional metrics of research impact, including public engagement with research. The COVID-19 pandemic provides a unique opportunity to study alternative metrics and the dissemination of scientific research given the heightened academic and public interest. This study analyzed Altmetric Attention Scores for the top 25 publications on COVID-19 and the top 25 non-COVID-19 publications in 2020. There were significantly higher levels of social attention scores across multiple metrics for COVID-19 articles than for non-COVID-19 articles for that year. There was a slightly higher goodness of fit between Altmetric Attention Scores and academic citations for COVID-19 publications than for non-COVID-19 publications, although trendline differences were not significant. These results suggest that researchers should be aware that their studies can become highly visible on publicly available social and news media platforms, especially during events of high interest (such as a global pandemic).

Intention to Receive COVID-19 Vaccine by U.S. Health Sciences University Employees.

OBJECTIVES: Understanding vaccine intentions and attitudes of health professionals is critical as the Pfizer-BioNTech and the Moderna COVID19 vaccines are being administered throughout the United States. This study estimates the level of vaccine hesitancy at a health sciences center in West Texas prior to the distribution of the vaccines. METHODS: An analytical cross-sectional study was performed via anonymous Qualtrics survey administered to approximately 4500 faculty, staff, postdoctoral research associates/medical residents, and employees at a multi-campus health sciences university in the United States. Respondents were asked demographic questions and intention to receive the vaccine. Factors associated with the intention to receive a vaccine were determined using logistic regression analysis. RESULTS: A total sample of 2258 subjects were evaluated (50.0% response rate). Among all respondents, 64.6% reported that they would probably or definitely receive the COVID-19 vaccine. Men had higher levels of intention to receive the vaccine (OR = 2.11, 95% CI 1.64-2.71); respondents who indicated yearly influenza vaccines are necessary were also more likely to receive the vaccine (OR = 6.04, 95% CI 4.70-7.75). Eighty-three percent of faculty and 56% of the staff reported intention to receive the vaccine. Respondents who had previously tested positive for COVID-19 reported more interest in receiving the vaccine (58.5% yes vs 41.5% no). CONCLUSION: In this study, the intention to receive the COVID-19 vaccination at a United States health sciences center falls below the necessary herd immunity estimates. Public health initiatives must be developed to decrease vaccine hesitancy, especially among health professionals.

COVID-19 Disease, Women's Predominant Non-Heparin Vaccine-Induced Thrombotic Thrombocytopenia and Kounis Syndrome: A Passepartout Cytokine Storm Interplay.

Coronavirus disease 2019 (COVID-19) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) constitute one of the deadliest pandemics in modern history demonstrating cardiovascular, gastrointestinal, hematologic, mucocutaneous, respiratory, neurological, renal and testicular manifestations and further complications. COVID-19-induced excessive immune response accompanied with uncontrolled release of cytokines culminating in cytokine storm seem to be the common pathogenetic mechanism of these complications. The aim of this narrative review is to elucidate the relation between anaphylaxis associated with profound hypotension or hypoxemia with pro-inflammatory cytokine release. COVID-19 relation with Kounis syndrome and post-COVID-19 vaccination correlation with heparin-induced thrombocytopenia with thrombosis (HITT), especially serious cerebral venous sinus thrombosis, were also reviewed. METHODS: A current literature search in PubMed, Embase and Google databases was performed to reveal the pathophysiology, prevalence, clinical manifestation, correlation and treatment of COVID-19, anaphylaxis with profuse hypotension, Kounis acute coronary syndrome and thrombotic events post vaccination. RESULTS: The same key immunological pathophysiology mechanisms and cells seem to underlie COVID-19 cardiovascular complications and the anaphylaxis-associated Kounis syndrome. The myocardial injury in patients with COVID-19 has been attributed to coronary spasm, plaque rupture and microthrombi formation, hypoxic injury or cytokine storm disposing the same pathophysiology with the three clinical variants of Kounis syndrome. COVID-19-interrelated vaccine excipients as polysorbate, polyethelene glycol (PEG) and trometamol constitute potential allergenic substances. CONCLUSION: Better acknowledgement of the pathophysiological mechanisms, clinical similarities, multiorgan complications of COVID-19 or other viral infections as dengue and human immunodeficiency viruses along with the action of inflammatory cells inducing the Kounis syndrome could identify better immunological approaches for prevention, treatment of the COVID-19 pandemic as well as post-COVID-19 vaccine adverse reactions.

A Retrospective Analysis and Comparison of Prisoners and Community-Based Patients with COVID-19 Requiring Intensive Care During the First Phase of the Pandemic in West Texas.

BACKGROUND: COVID-19 is a highly infectious disease which usually presents with respiratory symptoms. This virus is disseminated through respiratory droplets, and, therefore, individuals residing in close quarters are at a higher risk for the acquisition of infection. The prison population is at a significantly increased risk for infection. METHODS: Prisoners from the Montford Correctional facility in Lubbock, Texas, hospitalized in the medical intensive care unit at University Medical Center between March 1, 2020 and May 15, 2020 were compared to community-based patients hospitalized in the same medical intensive care unit. Clinical information, laboratory results, radiographic results, management requirements, and outcomes were compared. RESULTS: A total of 15 community-based patients with a mean age of 67.4 ± 15.5 years were compared to 5 prisoners with a mean age of 56.0 ± 9.0 years. All prisoners were men; 10 community-based patients were men. Prisoners presented with fever, dyspnea, and GI symptoms. The mean number of comorbidities in prisoners was 2.4 compared to 1.8 in community-based patients. Prisoners had significantly lower heart rates and respiratory rates at presentation than community-based patients. The mean length of stay in prisoners was 12.6 ± 8.9 days; the mean length of stay in community-based patients was 8.6 ± 6.5. The case fatality rate was 60% in both groups. CONCLUSIONS: Prisoners were younger than community-based patients but required longer lengths of stay and had the same mortality rate. This study provides a basis for comparisons with future studies which could involve new treatment options currently under study.
