Effect of low dose acetylsalicylic acid and anticoagulant on clinical outcomes in COVID-19, analytical cross-sectional study.

Background and aims: The therapeutic strategy for the treatment of known sequelae of COVID-19 has shifted from reactive to preventative. In this study, we aim to evaluate the effects of acetylsalicylic acid (ASA), and anticoagulants on COVID-19 related morbidity and mortality. Methods: This record-based analytical cross-sectional study targeted 539 COVID-19 patients in a single United States medical center between March and December 2020. Through a random stratified sample, we recruited outpatient (n = 206) and inpatient (n = 333) cases from three management protocols, including standard care (SC) (n = 399), low-dose ASA only (ASA) (n = 112), and anticoagulation only (AC) (n = 28). Collected data included demographics, comorbidities, and clinical outcomes. The primary outcome measure was inpatient admission. Exploratory secondary outcome measures included length of stay, 30-day readmission rates, medical intensive care unit (MICU) admission, need for mechanical ventilation, the occurrence of acute respiratory distress syndrome (ARDS), bleeding events, clotting events, and mortality. The collected data were coded and analyzed using standard tests. Results: Age, mean number of comorbidities, and all individual comorbidities except for asthma, and malignancy were significantly lower in the SC compared to ASA and AC. After adjusting for age and comorbidity via binary logistic regression models, no statistical differences were found between groups for the studied outcomes. When compared to the SC group, ASA had lower 30-day readmission rates (odds ration [OR] 0.81 95% confidence interval [CI] 0.35-1.88, p = 0.63), MICU admission (OR 0.63 95% CI 0.34-1.17, p = 0.32), ARDS (OR 0.71 95% CI 0.33-1.52, p = 0.38), and death (OR 0.85 95% CI 0.36-1.99, p = 0.71). Conclusion: Low-dose ASA has a nonsignificant but potentially protective role in reducing the risk of COVID-19 related morbidity and mortality. Our data suggests a trend toward reduced 30-day readmission rates, ARDS, MICU admissions, need for mechanical ventilation, and mortality compared to the standard management protocol. Further randomized control trials are needed to establish causal effects.

Transudative pleural effusion as an initial presentation of a disseminated cryptococcosis infection in a HIV-negative patient with cirrhosis.

To our knowledge, this is the first case report of a transudative pleural effusion with positive Cryptococcal antigen and culture. We describe a 32-year-old male with end-stage liver disease (ESLD) who presented to an outside hospital with dyspnea and a large pleural effusion. An initial pleural fluid analysis was positive for Cryptococcal Ag. However, the infection was eventually found to be widespread as he had positive Cryptococcal Ag and cultures in his pleural fluid, serum, and cerebrospinal fluid (CSF). His antimicrobial regiment was escalated from fluconazole to amphotericin B and flucytosine. His medical condition deteriorated, and the patient passed away. Due to its rarity and range of clinical severity, diagnosis of disseminated Cryptococcosis can be delayed. We present this case to bring awareness of this diagnosis as a differential in immunocompromised patients regardless of a transudative pleural effusion.

Identification of a High-risk Subgroup With Malignant Mitral Valve Prolapse Who Are Predisposed to Sudden Cardiac Death: A Review.

Mitral valve prolapse (MVP) affects approximately 170 million people worldwide; however, phenotypically, there is a wide variety of heterogeneity. In particular subsets, the incidence of sudden cardiac death is calculated to be 998 per 100,000 person-years, which is significantly increased when compared with the general population of MVP patients. Individuals with high-risk features have been identified as young females with bileaflet MVP and electrocardiogram findings of frequent complex ectopy, ST-T wave changes, and inferior T wave inversions. Supplemental imaging modalities in this subgroup demonstrate redundant leaflets and chordae on 2-dimensional transthoracic echocardiography along with varying severity of mitral annular disjunction. Detailed morphologic assessment by 3-dimensional echocardiography provides a quantitative assessment of annular disjunction along with left ventricular longitudinal and basal circumferential strain patterns. Late gadolinium enhancement on cardiac magnetic resonance imaging identifies diffuse and isolated left ventricle fibrosis involving the fascicles and papillary muscles, which has been visualized in isolation during autopsy. Findings of this review propose that sudden cardiac death as a result of malignant arrhythmias arises from automaticity, complex ectopy, and reentry at the level of the fascicles and papillary muscles. The repetitive mechanical stress provides a nidus for the development of both micro- and macrofibrosis easily identified by late gadolinium enhancement on cardiac magnetic resonance imaging. Escalation to electrophysiology studies and early intervention could provide new targeted lifesaving therapies.

Abdominal Cerebrospinal Fluid Pseudocyst as a Complication of Ventriculoperitoneal Shunt Placement.

The abdominal cavity has long been used for absorption of cerebrospinal fluid (CSF) in patients with hydrocephalus. Although the procedure is quite common, there are complications that can potentially arise following ventriculoperitoneal (VP) shunt insertion. Here, we report a case of a 39-year-old female patient in which a large abdominal pseudocyst was developed as a complication of VP shunt placement. Ultrasonographical evaluation of the abdomen showed a well-defined cystic mass lesion later confirmed on CT abdomen. She subsequently underwent surgical excision of the pseudocyst with resolution of previous symptoms. Clinicians should be aware of this complication since early diagnosis improves outcome and reduce patient's suffering and distress.

Rectal malakoplakia.

Malakoplakia is a rare chronic granulomatous disease with potential to affect multiple organs. Gastrointestinal involvement is considered one of the most common locations outside of the urinary tract. Herein, we present the case of a man who presented to our clinic with painless hematochezia. Physical examination findings were unremarkable; however, colonoscopy revealed a frond-like/villous, fungating, and polypoid nonobstructing circumferential mass in the rectum. Histopathological examination of the lesion revealed findings consistent with malakoplakia.

Correlations between Maternal, Breast Milk, and Infant Vitamin B12 Concentrations among Mother-Infant Dyads in Vancouver, Canada and Prey Veng, Cambodia: An Exploratory Analysis.

Vitamin B12 plays an essential role in fetal and infant development. In regions where animal source food consumption is low and perinatal supplementation is uncommon, infants are at risk of vitamin B12 deficiency. In this secondary analysis, we measured total vitamin B12 concentrations in maternal and infant serum/plasma and breast milk among two samples of mother-infant dyads in Canada (assessed at 8 weeks post-partum) and in Cambodia (assessed between 3-27 weeks post-partum). Canadian mothers (n = 124) consumed a daily vitamin B12-containing multiple micronutrient supplement throughout pregnancy and lactation; Cambodian mothers (n = 69) were unsupplemented. The maternal, milk, and infant total vitamin B12 concentrations (as geometric means (95% CI) in pmol/L) were as follows: in Canada, 698 (648,747), 452 (400, 504), and 506 (459, 552); in Cambodia, 620 (552, 687), 317 (256, 378), and 357 (312, 402). The majority of participants were vitamin B12 sufficient (serum/plasma total B12 > 221 pmol/L): 99% and 97% of mothers and 94% and 84% of infants in Canada and Cambodia, respectively. Among the Canadians, maternal, milk, and infant vitamin B12 were all correlated (p < 0.05); only maternal and infant vitamin B12 were correlated among the Cambodians (p < 0.001).
