Abstract
Pulmonary embolism (PE) poses a significant threat as the third leading cause of cardiovascular death, prompting the widespread use of CT pulmonary angiogram for rapid detection. Despite its prevalence, diagnostic accuracy remains variable among radiologists. The emergence of artificial intelligence (AI), notably through convolutional neural networks and deep learning reconstruction, offers a promising avenue to enhance PE detection. AI demonstrates superior sensitivity and negative predictive values, reducing the risk of missed diagnoses. Implementation of AI-based worklist prioritization substantially shortens detection and notification times, streamlining radiological workflows. However, it is crucial to underscore that AI acts as a complement, not a replacement, for radiologists, synergizing with human expertise. As AI integration progresses, it holds the potential to significantly improve diagnostic accuracy and efficiency in pulmonary embolism detection while maintaining the essential role of human judgment in medical decision-making.

Abstract
Pulmonary cryptococcosis, although rare, maybe seen in both immunocompromised and immunocompetent patients. Cryptococcosis presenting as a lung mass mimicking lung cancer is very rare. Here, we report our experience with pulmonary cryptococcosis presenting as a lung mass mimicking malignancy in an immunocompetent patient. In this case, the patient presented to us with left-sided pleural effusion and lung mass on computed tomography (CT) of the chest. Bronchoscopy and endobronchial ultrasound (EBUS)-guided fine needle aspiration cytology (FNAC) was performed, which showed cryptococcal organisms. He responded well to oral anti-fungal therapy without any need for surgical interventions.

Abstract
Emphysematous cystitis is defined by the presence of air within the bladder wall or lumen in imaging studies with increased incidence in elderly women and diabetics. It is a result of gas-forming organisms like Klebsiella and E. coli but can be caused by fungi such as Candida and Aspergillus as well with a wide spectrum of clinical presentations. In this article, we present a case of a 77-year-old female with diabetes mellitus who presented to the hospital with a chief complaint of left lower quadrant abdominal pain. Abdominal imaging revealed emphysematous cystitis, paraspinal abscess, and air in the thoracic and lumbar vertebrae. Laboratory results showed leukocytosis, lactic acidosis, and urinalysis significant for urinary tract infection but no positive urine or blood cultures. The patient was admitted to the intensive care unit for septic shock and was treated with mechanical ventilation, vasopressor support, and prompt antimicrobial therapy following which the requirement of vasopressors ceased on the third day of admission. The decision was then made by the family to pursue hospice care, following which mechanical ventilation was discontinued and the patient transferred to inpatient hospice. With this case report, we aim to add to the existing literature regarding the spread of intra-abdominal infections and go over a brief review of the currently available literature. From our review, we would like to conclude that the presence of pneumoracchis, especially in the setting of an intra-abdominal infection, is a poor prognostic marker, and timely diagnosis and treatment of potential causes are required to reduce mortality.

Abstract
Marijuana or cannabis has been one of the most widely used recreational drugs, in the United States. However, a sinister counterpart has emerged in recent times: K2/Spice, a synthetic rendition of tetrahydrocannabinol (THC), capturing increasing popularity. Alarming reports have linked this synthetic compound to a multitude of life-threatening complications, ranging from acute kidney injury (AKI) from direct nephrotoxicity to cardiac arrest. Here we present the case of a 34-year-old man who presented with hemoptysis, later found to have diffuse alveolar hemorrhage (DAH) on the investigation after smoking K2/Spice successfully treated with a course of intravenous steroids. The case presented underscores the urgent need for increased awareness about the potential complications associated with synthetic compounds like K2/Spice, such as diffuse alveolar hemorrhage, and the importance of developing effective treatment strategies.

Abstract
Chronic obstructive pulmonary disease (COPD) is a complex disease pathology of the lungs that has a significant impact on global health. It has been a major contributor to global mortality and morbidity, with COPD exacerbations posing a substantial economic burden on the healthcare systems. Appropriate triaging of patients with COPD exacerbation is crucial to reduce the burden of hospitalization, especially in the intensive care unit (ICU). Understanding the significance of exacerbation scores in triage decision-making is essential for improving outcomes and optimizing patient care. To aid this triage decision-making, several scoring systems have been developed. This review article aims to discuss the different scores, including assessment of Confusion, Urea, Respiratory rate, Blood pressure, and Age (≥65 years) (CURB-65); Dyspnoea, Eosinopenia, Consolidation, Acidaemia and atrial Fibrillation (DECAF), Neutrophil to lymphocyte ratio (NLR); Platelet-lymphocyte ratio (PLR); Pneumonia severity index/Pneumonia Patient Outcomes Research Team (PSI/PORT); and elevated BUN, Altered mental status, Pulse, Age (>65 years) (BAP-65), and their role in triaging COPD exacerbations. Proper triaging allows for the appropriate allocation of resources and timely interventions based on severity. Further research and validation are needed to establish the optimal use and integration of these scores in clinical practice, particularly in ICU settings.

Abstract
Sickle cell disease (SCD) is a prevalent inherited blood disorder with various ocular manifestations, including sickle cell retinopathy (SCR), characterized by retinal microcirculation impairment and ischemic complications. We present the case of a 21-year-old male with sickle cell trait who experienced a sudden, painless loss of vision in his left eye. Ophthalmologic examination revealed vitreous hemorrhage and neovascularization, indicating SCR. Initial treatment with hydroxyurea and exchange transfusions led to partial improvement. However, due to persistent vitreous hemorrhage, the patient underwent a vitrectomy. The sickle cell trait affects a large global population, and its retinopathy is a rare but severe complication. The pathogenesis and risk factors for SCR are similar to those for SCD. The diagnosis of SCR is established through fundoscopic examination and graded based on Goldberg's classification. Management involves a multidisciplinary approach targeting systemic illness and visual defects, including hydroxyurea, photocoagulation, anti-vascular endothelial growth factors, and vitrectomy. Awareness, early diagnosis, and timely intervention are essential to preventing vision-threatening complications in sickle cell trait patients with SCR.

Abstract
To expand our limited knowledge of COVID-19-related outcomes in patients admitted to inner-city intensive care unit (ICU across multiple infection waves. This retrospective study compared patients admitted to the ICU in Bronx, NY, during 3 COVID-19 waves (March 2020 to February 2022). Outcomes included in hospital mortality, length of stay (LOS), use of mechanical ventilation, and discharge disposition. The study included 716 patients (343, 276, and 97 in the first, second, and third COVID-19 waves, respectively). The number of days on mechanical ventilation and LOS were lower in the first wave. Of the 345 discharged patients, 37% went home directly, whereas 11% were discharged to a skill nursing facility. More patients went home during the second and third waves. Mortality decreased from the first to the third waves (57%-37%; P < .001). Predictors of mortality included age, male gender, COPD, shock, acute kidney injury (AKI), dialysis requirement, and mechanical ventilation. The decreased mortality and better discharge disposition of these inner-city patients during the second and third waves is encouraging, as this population historically had a high COVID-19-related mortality risk.

Abstract
Background Right ventricular (RV) dysfunction in acute COVID-19 was reported to be associated with poor prognosis. We studied the association between parameters of RV dysfunction and in-hospital mortality during the surges caused by different SARS-CoV-2 variants. Methods In a retrospective single-center study, we enrolled 648 consecutive patients hospitalized with COVID-19 [66 (10 %) hospitalized during the alpha variant surge, 433 (67 %) during the delta variant surge, and 149 (23 %), during the omicron variant surge]. Patients were reported from a hospital with an underreported population of mostly African American and Hispanic patients. Patients were followed for a median of 11 days during which in-hospital death occurred in 155 (24 %) patients [Alpha wave: 25 (38 %), Delta Wave: 112 (26 %), Omicron wave: 18 (12 %), p < 0.001]. Results RV dysfunction occurred in 210 patients (alpha: 32 %, 26 %, delta: 29 %, and omicron: 49 %, p < 0.001) and was associated with higher mortality across waves, however, independently predicted in-hospital mortality in the Alpha (HR = 5.1, 95 % CI: 2.06–12.5) and Delta surges (HR = 1.6, 95 % CI: 1.11–2.44), but not in the Omicron surge. When only patients with RV dysfunction were compared, the mortality risk was found to decrease significantly from the Alpha (HR = 13.6, 95 % CI: 3.31–56.3) to the delta (HR = 1.93, 95 % CI: 1.25–2.96) and to the Omicron waves (HR = 11, 95 % CI: 0.6–20.8). Conclusions RV dysfunction continues to occur in all strains of the SARS-CoV-2 virus, however, the mortality risk decreased from wave to wave likely due to evolution of better therapeutics, increase rate of vaccination, or viral mutations resulting in decrease virulence.

Abstract
Antipsychotic medications have been well-established to potentially cause extrapyramidal side effects (EPS) including hyperkinesia, tremor, dyskinesia, dystonia, and parkinsonism. Rhabdomyolysis secondary to extrapyramidal symptoms in patients under antipsychotics is a relatively rare presentation to be observed in patients. In this report, we present a 64-year-old female with rhabdomyolysis following a once-monthly injection of long-acting injectable (LAI) paliperidone palmitate (Invega Sustenna). The patient developed extrapyramidal symptoms one day after the paliperidone injection. She presented with acute dystonia in the form of antecollis, without any evidence of generalized myalgia or kidney involvement. Laboratory investigations demonstrated a creatine kinase (CK) level of 3239 unit/L on admission. The patient’s symptoms were resolved after the administration of benztropine and cyclobenzaprine and CK levels improved after IV hydration. A high index of suspicion in the investigation of rhabdomyolysis for patients presenting with extrapyramidal symptoms being treated with long-acting injectable antipsychotics leads to prompt diagnosis, early treatment, and reduction in renal and cardiac toxicities in the aforementioned population.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection triggers elevated levels of circulating cytokines and immune-cell hyperactivation, called a cytokine storm, which leads to dysregulated immune response not only towards the pathogen itself but also contributes to cellular, vascular injury and multiorgan dysfunction. The cytokine-induced endothelial inflammation and vascular pathology of COVID-19 is well reported in post-mortem biopsies and several cases reporting small, medium and large vessel micro/macro thrombotic events and vasculitis in multiple organs. So far, few cases have been reported with newly diagnosed antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis at the time of acute COVID-19 infection. The exact pathophysiology of SARS-CoV-2 and ANCA-associated vasculitis continues to be studied and reviewed. Here we report a case of a 60-year-old female who presented to our institution with sudden onset of shortness of breath and hemoptysis. A detailed history revealed a recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Labs showed elevated serum creatinine, urine analysis with large blood and nephrotic range proteinuria. CT chest was remarkable for abnormal appearance of the parenchyma bilaterally compatible with a crazy paving pattern, suggesting pulmonary alveolar proteinosis versus diffuse alveolar hemorrhage. Vasculitis was suspected and the patient was started on IV corticosteroids and plasmapheresis. Diagnostic workup was positive for antineutrophil cytoplasmic antibodies-myeloperoxidase (ANCA-MPO), anti-Sjögren's syndrome-related antigen A autoantibodies (anti-SS-A) and antinuclear antibodies (ANA). Renal biopsy confirmed focal segmental necrotizing, crescentic and sclerosing glomerulonephritis, pauci-immune type, anti-MPO antibody/P-ANCA associated. A diagnosis of microscopic polyangiitis was made and she was started on rituximab immunosuppressive therapy following which she showed clinical improvement. In this document, we present a unique case of microscopic polyangiitis possibly induced by SARS-CoV-2 infection confirmed by renal biopsy and clinical presentation. In the current setting of a global pandemic, we strongly recommend that vasculitis be high on the differential diagnosis in patients who are currently infected or had been infected with SARS-CoV-2 and present with acute kidney injury (AKI).
