Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019, coronavirus disease 2019 (COVID-19) has caused significant global morbidity and mortality. Although initially recognized as a respiratory illness, COVID-19 is now understood to be a systemic disease with substantial cardiovascular involvement. Both patients with pre-existing cardiovascular disease and those without prior cardiac conditions may develop a wide range of cardiovascular complications during and after acute infection. Reported complications include myocardial injury, myocarditis, heart failure, arrhythmias, and thromboembolic events, all of which contribute to increased disease severity and mortality. This narrative review summarizes current evidence on cardiovascular complications associated with COVID-19 among adult patients in the United States, with particular attention to differences between individuals with pre-existing cardiovascular disease and those who develop new cardiovascular pathology following SARS-CoV-2 infection. This review discusses proposed mechanisms of cardiovascular injury, clinical manifestations, diagnostic approaches, and current management strategies. By summarizing current knowledge, this review aimed to increase awareness of COVID-19-related cardiovascular complications, support timely recognition in emergency and inpatient settings, and assist clinicians in improving patient outcomes.
This investigation offers a cohesive simulation-based platform aimed at quantifying chemical exposure dangers in crewed extraterrestrial travel, specifically addressing volatile organic compounds (VOCs) and particulate matter originating from spacecraft subsystems. Custom computational fluid dynamics (CFD) simulations, executed with both COMSOL Multiphysics and ANSYS Fluent, modeled the microgravity-governed dispersion of these chemicals, revealing model-predicted peak cabin VOC concentrations of 1.8–2.3 ppm in confined zones and particulate concentration maxima of 0.12–0.16 mg/m³. The study characterized hydrazine and heavy metal species qualitatively owing to their rarity in typical mission sets. Molecular docking analyses were carried out using an appropriate docking engine, while PyMOL and ChimeraX were used for structural visualization and interaction analysis. These analyses were used as supportive mechanistic indicators of possible chemical-biomolecular interactions rather than as direct standalone measures of toxicological potency. The observed changes in binding energies of VOC-derived DNA adducts, including a 14–18
Takotsubo cardiomyopathy (TTC) typically presents in post-menopausal females with chest pain, dyspnea, or palpitations and often mimics acute coronary syndrome. This case report describes a unique presentation of TTC in an elderly patient who exhibited gastrointestinal and musculoskeletal symptoms without cardiopulmonary complaints. This constellation of symptoms has not been previously described in the literature. The patient was ultimately diagnosed with TTC with evidence of ST-T wave abnormalities on ECG, elevated serum troponin levels, a reduced left ventricular ejection fraction, the absence of significant coronary artery disease on cardiac catheterization, and regional wall abnormalities on transthoracic ultrasound and left ventriculography. It contributes to our current understanding of the varied clinical presentation seen in TTC, which may help clinicians refine their differential diagnoses, provide earlier treatment, prevent misdiagnosis, and enhance patient care outcomes.
BACKGROUND Guttate psoriasis is a form of psoriasis that often occurs following infections and is most commonly triggered by group A Streptococcus. The link between streptococcal pharyngitis and the development of guttate psoriasis is well documented in younger populations; however, this presentation in older adults is less common. Additionally, older adult populations can have multiple comorbidities that could influence the development and clinical course of guttate psoriasis. CASE REPORT We report the case of a 66-year-old woman with multiple comorbidities, including type 2 diabetes mellitus, vitamin D deficiency, colon cancer treated with surgical resection, and endometriosis, who developed guttate psoriasis following a confirmed episode of streptococcal pharyngitis. Initially, the patient's condition was misdiagnosed as tinea versicolor, leading to delays in appropriate treatment. After further dermatologic evaluation and laboratory investigations, the diagnosis of guttate psoriasis was more firmly established, allowing for more tailored treatment decisions. CONCLUSIONS This case highlights guttate psoriasis as a rare post-streptococcal complication in a 66-year-old woman, emphasizing the importance of clinical awareness and accurate diagnosis in older adults with recent upper respiratory infections. Although the exact mechanism of guttate psoriasis development remains unclear, its distinct clinical features allow for its recognition in patients of all ages. Guttate psoriasis also contributes to the understanding of the varied clinical manifestations of streptococcal pharyngitis, particularly in patients with complex medical histories.
Triplet births, particularly those achieved by assisted reproductive technologies, entail markedly elevated maternal and fetal risks, including hypertensive diseases. Intracerebral hemorrhage is an uncommon but devastating complication during the postpartum period. The main aim of our work is to throw light on the association of intracerebral hemorrhage in pregnancy with severe consequences. We presented and compared similar cases. We present a rare case of a 34-year-old lady who was pregnant with triplets conceived by in vitro fertilization. She had a significant intracerebral hemorrhage 2 h post elective lower-segment cesarean section. Her blood pressure was normal during prenatal and perioperative periods. A postoperative hypertensive emergency (200/110 mmHg) resulted in neurological decline and seizure, necessitating urgent airway protection and neuroimaging. The MRI indicated a substantial intracerebral hemorrhage with intraventricular and subarachnoid extension. Neurosurgical procedures included external ventricular drainage and decompressive craniectomy. The patient exhibited modest neurological improvement throughout neurocritical care. This case shows that women who have triplets are at a greater risk of experiencing a serious increase in blood pressure after giving birth, even if they had normal blood pressure before. High-risk factors like advanced maternal age and the use of assisted reproductive technologies further increase the risk of triplet pregnancy. Our case highlights the importance of frequent blood pressure monitoring postpartum. Immediate neurological consultation and, if necessary, intervention followed by intensive neurocritical care are central to management for better outcomes for the patient. All healthcare teams need to be alert for possible complications from pregnancy, like intracerebral hemorrhage, especially in high-risk groups such as older patients with multiple pregnancies or those who have used assisted reproductive techniques.
