Covid-19 Case Complicated With Organizing Pneumonia And Pneumothorax: A Case Report, Tammy E. Phillips, Hammad A. Bhatti, Minh Q. Ho

The University of Louisville Journal of Respiratory Infections

Organizing pneumonia can be idiopathic or caused by multiple etiologies, including viral or bacterial pneumonia, drugs, and autoimmune disorders. It can rarely lead to cyst formation and pneumothorax with the exact mechanism remaining unclear. This case presents a previously healthy 50-year-old male who contracted COVID-19 with subsequent development of organizing pneumonia and pneumothorax. Patients presenting with hypoxic respiratory failure due to COVID-19 should be screened for organizing pneumonia upon discharge. This case also illustrates the importance of following such patients radiologically to monitor interstitial lung disease and consider pneumothorax for patients re-presenting with acute symptoms.

The Correlation Between Vaccine Hesitancy And Privilege: Exploring The Degree To Which Education And Income Foster Resistance To Vaccination Efforts, Sophie Goldenberg

Independent Study Project (ISP) Collection

Vaccine hesitancy is a public health issue of growing concern. Extensive pre-existing literature offers several explanations and conflicting viewpoints regarding reluctance toward vaccinations. However, minimal research has been done exploring the upstream social determinants driving vaccine hesitancy. Utilizing academic and gray literature and interviews with experts in the field, this study addresses this gap in knowledge with the research question: To what extent does privilege impact vaccine hesitancy and resistance? Vaccine hesitancy appears globally and is particularly concerning given the re-emergence of vaccine-preventable diseases (VPDs). Additionally, due to inconsistent causes, vaccine hesitancy is difficult to combat. In referencing the history …

A Streptococcus Pneumoniae Lineage Usually Associated With Pneumococcal Conjugate Vaccine (Pcv) Serotypes Is The Most Common Cause Of Serotype 35b Invasive Disease In South Africa, Following Routine Use Of Pcv, Kedibone M. Ndlangisa, Mignon Du Plessis, Stephani Lo, Linda De Gouveia, Chrispin Chaguza, Martin Antonio, Brenda Kwambana-Adams, Jennifer Cornick, Dean B. Everett, Sadia Shakoor

Department of Pathology and Laboratory Medicine

Pneumococcal serotype 35B is an important non-conjugate vaccine (non-PCV) serotype. Its continued emergence, post-PCV7 in the USA, was associated with expansion of a pre-existing 35B clone (clonal complex [CC] 558) along with post-PCV13 emergence of a non-35B clone previously associated with PCV serotypes (CC156). This study describes lineages circulating among 35B isolates in South Africa before and after PCV introduction. We also compared 35B isolates belonging to a predominant 35B lineage in South Africa (GPSC5), with isolates belonging to the same lineage in other parts of the world. Serotype 35B isolates that caused invasive pneumococcal disease in South Africa in …

The Aoc In The Age Of Covid—Pandemic Preparedness Planning In The Federal Courts, Zoe Niesel

St. Mary's Law Journal

The 2020 COVID-19 pandemic created a crisis for American society—and the federal courts were not exempt. Court facilities came to a grinding halt, cases were postponed, and judiciary employees adopted work-from-home practices. Having court operations impacted by a pandemic was not a new phenomenon, but the size, scope, and technological lift of the COVID-19 pandemic was certainly unique.

Against this background, this Article examines the history and future of pandemic preparedness planning in the federal court system and seeks to capture some of the lessons learned from initial federal court transitions to pandemic operations in 2020. The Article begins by …

Background: Mask use is a cost-effective measure to decrease COVID-19 transmission. Mask mandates intend to increase mask compliance but are often ambiguous when it comes to public outdoor spaces.

Methods: We used a field audit study to examine mask use in New York City neighborhood parks during COVID-19. 1453 park visitors were observed in 13 parks during July–August 2020 using a modified and validated park use audit tool (System for Observing Play and Recreation in Communities) that included items on general and proper mask use (i.e., mask covering both nose and mouth). Generalized estimating equation regression was used to determine …

Consultation/Liaison Psychiatry During Covid-19, Robert Frierson, Steven B Lippmann

The University of Louisville Journal of Respiratory Infections

Consultation/liaison psychiatrists care for people with co-existing medical and psychologic difficulties. The coronavirus pandemic is stressful for patients and their psychiatric caregivers. Patients have lost support systems and harbor fears about exposing family to the virus. COVID-19 sometimes exacerbates previous psychiatric conditions, while diminishing intimacy with physicians. Everyone is oversaturated with COVID-19-related news focusing on rising concerns about the illness and about jobs, school, and housing insecurities.

The psychiatrist maintains a hospital presence despite fear of contracting the disease. Challenges include addressing staff morale, evidencing empathy despite telecommunication devices, and treating anxiety, depression, sleep phobias, post intubation flashbacks, COVID-19-induced cognitive …

The Role Of Interspecies Recombination In The Evolution Of Antibiotic-Resistant Pneumococci, Joshua C. D'Aeth, Mark Pg Van Der Linden, Lesley Mcgee, Herminia De Lencastre, Paul Turner, Jae-Hoon Song, Stephanie W. Lo, Rebecca A. Gladstone, Gps Consortium, Sadia Shakoor

Department of Pathology and Laboratory Medicine

Multidrug-resistant Streptococcus pneumoniae emerge through the modification of core genome loci by interspecies homologous recombinations, and acquisition of gene cassettes. Both occurred in the otherwise contrasting histories of the antibiotic-resistant S. pneumoniae lineages PMEN3 and PMEN9. A single PMEN3 clade spread globally, evading vaccine-induced immunity through frequent serotype switching, whereas locally circulating PMEN9 clades independently gained resistance. Both lineages repeatedly integrated Tn916-type and Tn1207.1-type elements, conferring tetracycline and macrolide resistance, respectively, through homologous recombination importing sequences originating in other species. A species-wide dataset found over 100 instances of such interspecific acquisitions of resistance cassettes and flanking …

A 72-year-old male presented to the emergency department with a chief complaint of diarrhea after having tested positive for COVID-19 two days prior. He initially had minimal respiratory complaints, but was eventually transferred to the intensive care unit for acute hypoxic respiratory failure. In addition to dexamethasone, remdesivir, and antibiotics, the patient was treated with baricitinib, a Janus kinase inhibitor that was recently granted emergency use authorization by the Food and Drug Administration for treatment of hospitalized patients with COVID-19. He had an extensive and complicated hospital course and had to be placed on mechanical ventilation, ultimately undergoing tracheostomy. After …

Clinical Consequences And Determinants Of False Positive Blood Cultures In Adult Hospitalized Patients, Sidra Liaquat

Theses & Dissertations

Blood cultures are the gold standard for detecting blood stream infections. However, in the US, 0.6-6% of all blood cultures get contaminated leading to adverse clinical outcomes such as unnecessarily prolonged hospital stay and antibiotic therapy. Using electronic medical records, we explored the clinical outcomes and patient-specific risk factors of contaminated blood cultures in an era where rapid blood culture testing was being utilized to provide blood culture results within hours. Rapid blood culture test results can help clinicians in early and more effective management of patients with contaminated blood cultures, thus improving clinical outcomes. We also studied the impact …
