The impact of the moon cycles’ in different seasons on heart failure patients’ hospitalization and length of stay
The natural forces of the lunar cycle and seasonal solstice variation on the water surfaces have been studied extensively but not on patients with fluid problems such as heart failure (HF). This retrospective review investigates these temporal effects on admission rates of patients with heart failure and length of stay. In this study, we try to answer the following questions: Do moon cycles (full moon vs new moon) significantly affect the number of patients admitted? and Do moon cycles significantly affect the patient’s hospital length of stay (LOS?). All patients with HF exacerbation admission between January 1, 2016 to December 31, 2019, were filtered according to admission date based on the lunar calendar. Patients admitted on the day of, the day before, and the day after a new and full moon were included. Question 1, Poisson regression models were employed. The overdispersion obtained from the AER package was 1.63. All analyses were performed using R (R Core Team). A total of 758 patients were admitted during lunar cycles, 50.1% (N = 380) were admitted during the new moon and 49.4% (N = 378) during the full moon. The mean age is 78.4 (SD 7.2), the mean BMI is 28.8 (SD 6.7), and the mean LOS is 5.6 (SD 3.4) with no significant differences in patients admitted during both of the moon cycles. The seasons variable showed statistically significant coefficients, with the summer season (S2) having the highest impact (coefficient 0.85, P = .001). Some interaction between Moon-Cycle, summer season, and BMI influenced patient admissions during lunar cycles (coefficient = 0.49 P ≤ .001). This study showed that the moon cycle may impact patients with HF during the summer season only. Prospective studies are needed on a national level to investigate further the impact of the moon cycle on HF patients. This will help improve patient outcomes and pathogenesis, and there is excellent potential for reducing medical costs.

Assessing the influence of COVID-19 pandemic on thirty days readmission rate based on patient’s demographics, substance use, and insurance
Providing the highest quality care with no biases is the goal of every healthcare system. As a part of that goal hospital readmission has been investigated due to its impact on healthcare cost and case fatality rate in patient outcome. Patient's demographics, substance use and insurance barriers have been investigated as factors for readmission rate but the impact of COVID-19 pandemic on those biases and barriers have not been studied extensively yet. In our retrospective cross-sectional study, we placed the scope on readmission rate with the intention to investigate any relation with patient's demographics including ethnicity, gender, language, substance use and insurance barriers and if there has been any change in the area pre and post COVID-19 pandemic. Total of 1713 readmitted patients were identified and split into 893 pre-COVID-19 and 820 post COVID-19 pandemic. Our multivariable analysis showed that the rate of readmissions during the COVID-19 pandemic was statistically higher among substance users (p = 0.003) and Medicaid insured (p = 0.038), and less likely among Spanish speakers p = 0.003. This study is limited due to small sample size and does not accurately represent the full population of the United States. Our hope is to further investigate the impact of COVID-19 pandemic on the readmission rate and to identify any influencing factors, biases, and barriers that contributed to the increased rate of readmission to learn and avoid future readmissions during straining times in medicine such as during COVID-19 pandemic.

Cardiovascular disease in women: A review of spontaneous coronary artery dissection
Research has demonstrated the disproportionate quality of care for women with cardiovascular disease. These findings have prompted a renewed focus on cardiovascular disease awareness and disease prevention in women. Spontaneous coronary artery dissection (SCAD) is a significant cause of myocardial infarction (MI) and sudden death that primarily affects women. ongoing research has led to improved diagnostic capabilities and changes in approaches to initial and long-term management most importantly this research has provided evidence that SCAD is more common than previously thought and must be evaluated and treated differently from atherosclerotic MI. The difference between SCAD and atherosclerotic MI is highlighted in high rates of recurrent disease, gender distribution, association with exogenous hormones, pregnancy, migraine, physical and emotional stress triggers, concurrent systemic arteriopathies, and connective tissue disease. In this review, we provide updated insights and a summary of the epidemiology, risk factors, clinical presentation, diagnosis, treatment options, prognosis, and recurrence prevention of SCAD. We aim to provide a review of SCAD as a focus on cardiovascular disease awareness and disease prevention in women.

A Rare Case of Raoultella planticola and Enterococcus casseliflavus Coinfection
Raoultella planticola, a Gram-negative bacterium, is a nonmotile rod usually found in soil and aquatic environments. It can be found in association with gastrointestinal malignancy. Enterococcus casseliflavus is a rare vancomycin-resistant Enterococcus that is responsible for some bacteremia. Our case describes a unique presentation of colonization with both R. planticola and E. casseliflavus isolated from the biliary stent isolates of a patient with known pancreatic malignancy and concomitant E. casseliflavus bacteremia. This is the first case ever reported of infection with both species.

Lung Biopsy as Rare Cause of Thromboembolic Stroke: A Case Report
Unusual clinical course CT-guided lung biopsy is a routine procedure used to evaluate suspicious pulmonary lesions that may arise from malignancy or infectious etiology. Common complications such as pneumothorax, bleeding, and rare cases of air embolisms leading to stroke have been documented as well. It is reported that there is a 0.06–0.08% risk of air embolism resulting in stroke in patients undergoing CT-guided lung biopsy. However, other causes of ischemic stroke following lung biopsy should be considered. A 36-year-old obese man presented with chronic shortness of breath, intermittent fever, and night sweats. Chest CT showed multiple bilateral pulmonary nodules with basilar predominance, and laboratory test results that showed no acute infections, a negative TB QuantiFERON, and a normal transthoracic echocardiogram. Therefore, elective lung biopsy was performed to direct future medical therapy. Shortly after the procedure, the patient reported having right-sided vision loss and decreased sensation on the right half of his face, arms, and legs. Non-contrast CT of the brain showed no hemorrhage and no air intracranially. Therefore, following a Neurology consult, the stroke protocol was initiated, which resulted in tPA being administered. TPA use resolved the patient’s symptoms, with no signs of hemorrhage. Air embolisms have commonly been the cause of strokes following CT-guided lung biopsies, which can be detected on CT brain with signs of air intracranially. However, our case presents an ischemic cause of stroke with no evidence of air embolisms intracranially. Multidisciplinary stroke team consultations and consideration of alternative causes of stroke following CT-guided lung biopsy can be lifesaving, as urgent medical therapy can be delayed without proper considerations.

Case Report: Infective Endocarditis of Mechanical Aortic Valve Due to Neisseria elongata Bacteremia
Objective: Unknown etiology Background: Neisseria etongata is a infrequent cause of infective endocarditis (IE). Although considered a commensal bacterium of the human nasopharynx, N. etongata has been shown to be the cause of significant disease in humans, namely endocarditis, osteomyelitis, and septicemia. Case Report: We report the case of a 53-year-old man with a past medical history of mechanical aortic valve who presented to the hospital for evaluation of eleven days of recurrent and relapsing fevers and was admitted for severe sepsis with concern for endocarditis. Blood cultures revealed N. etongata bacteremia, and an echocardiogram did not show any vegetations, although it was limited by mechanical aortic valve shadowing. The patient recovered after six weeks of treatment with intravenous ceftriaxone and oral ciprofloxacin. Conclusions: Clinicians should be aware of the possibility of the previously considered non-pathogenic N. etongata as a source of IE caused by gram-negative organisms, as it can potentially cause severe disease and multiple complications. Our case additionally highlights that IE has highly variable clinical presentations. Thus, it is essential to utilize the Duke criteria as only a clinical guide for the diagnosis of IE rather than a substitute for clinical judgment and the decision to treat a patient with suspected IE.

Refractory Spontaneous Bacterial Empyema in Cirrhotic Patient
Spontaneous bacterial empyema (SBEM), also called spontaneous bacterial pleuritis, is an infection of the pleural space that arises in the setting of cirrhosis and, by definition, the absence of pneumonia. It is likely underdiagnosed as its symptoms are nonspecific and it lacks standardized diagnostic and therapeutic recommendations. SBEM represents a distinct complication of hepatic hydrothorax with different pathogenesis, presentation, and treatment strategy from those of empyema secondary to pneumonia. Surprisingly, nearly 40 of episodes of spontaneous empyema are not associated with spontaneous bacterial peritonitis. Although SBEM is amenable to prompt antibiotic therapy, it has a high rate of mortality and morbidity. A high clinical suspicion is crucial for patient survival and timely initiation of appropriate antibiotics. Increased understanding, recognition, and standardization of treatment would help alleviate the relatively high burden of SBEM. In this case vignette, we provide a review of the relevant literature, and we describe a rare case of SBEM in a patient with a history of alcohol-associated liver cirrhosis and prior episode of spontaneous bacterial peritonitis (SBP). SBEM was diagnosed with thoracentesis and analysis of the aspirate, and he was treated with ceftriaxone with resolution of his presenting abdominal pain and leukocytosis.
