RESUMEN
A substantial number of patients may experience systemic inflammatory response syndrome (SIRS) and related adverse events after transcatheter aortic valve implantation and endovascular aortic aneurysm repair. Although a clear etiology has not been established, endothelial disruption and tissue-ischemic response secondary to the foreign material may represent the trigger events. A latency period (0 to 48 hours) may occur between the initial injury and onset of symptoms mirroring an initial local response followed by a systemic response. Clinical presentation can be mild or severe depending on external triggers and characteristics of the patient. Diagnosis is challenging because it simulates an infection, but lack of response to antibiotics, negative cultures are supportive of SIRS. Increased in-hospital stay, readmissions, major cardiovascular events, and reduced durability of the device used are the main complications. Treatment includes non-steroidal anti-inflammatory drugs or corticosteroids. In conclusion, further studies are warranted to fully explore pathophysiologic mechanisms underpinning SIRS and the possibility of enhancing device material immune compatibility to reduce the inflammatory reaction of the host tissue.

BACKGROUND: Myocardial injury is frequent among patients hospitalized with coronavirus disease-2019 (COVID-19) and is associated with a poor prognosis. However, the mechanisms of myocardial injury remain unclear and prior studies have not reported cardiovascular imaging data. OBJECTIVES: This study sought to characterize the echocardiographic abnormalities associated with myocardial injury and their prognostic impact in patients with COVID-19. METHODS: We conducted an international, multicenter cohort study including 7 hospitals in New York City and Milan of hospitalized patients with laboratory-confirmed COVID-19 who had undergone transthoracic echocardiographic (TTE) and electrocardiographic evaluation during their index hospitalization. Myocardial injury was defined as any elevation in cardiac troponin at the time of clinical presentation or during the hospitalization. RESULTS: A total of 305 patients were included. Mean age was 63 years and 205 patients (67.2%) were male. Overall, myocardial injury was observed in 190 patients (62.3%). Compared with patients without myocardial injury, those with myocardial injury had more electrocardiographic abnormalities, higher inflammatory biomarkers and an increased prevalence of major echocardiographic abnormalities that included left ventricular wall motion abnormalities, global left ventricular dysfunction, left ventricular diastolic dysfunction grade II or III, right ventricular dysfunction and pericardial effusions. Rates of in-hospital mortality were 5.2%, 18.6%, and 31.7% in patients without myocardial injury, with myocardial injury without TTE abnormalities, and with myocardial injury and TTE abnormalities. Following multivariable adjustment, myocardial injury with TTE abnormalities was associated with higher risk of death but not myocardial injury without TTE abnormalities. CONCLUSIONS: Among patients with COVID-19 who underwent TTE, cardiac structural abnormalities were present in nearly two-thirds of patients with myocardial injury. Myocardial injury was associated with increased in-hospital mortality particularly if echocardiographic abnormalities were present.

The emergence of a new coronavirus disease (coronavirus disease 2019 [COVID-19]) has raised global concerns regarding the health and safety of a vulnerable population. Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) incites a profound inflammatory response leading to tissue injury and organ failure. COVID-19 is characterized by the bidirectional relationship between inflammation and thrombosis. The clinical syndrome is propelled by inflammation producing acute lung injury, large-vessel thrombosis, and in situ microthrombi that may contribute to organ failure. Myocardial injury is common, but true myocarditis is rare. Elderly patients, those with established cardiovascular disease, and mechanically ventilated patients face the highest mortality risk. Therapies for COVID-19 are evolving. The antiviral drug remdesivir, dexamethasone, transfusion of convalescent plasma, and use of antithrombotic therapy are promising. Most require additional prospective studies. Although most patients recover, those who survive severe illness may experience persistent physical and psychological disabilities.

With aging of HIV populations, there is concern that Alzheimer's disease (AD) may become prevalent and difficult to distinguish from HIV-associated neurocognitive disorders. To date, there are no reports documenting histologically verified Alzheimer's neuropathology in individuals with HIV and dementia. Herein, we report two antiretroviral-treated, virally suppressed, HIV-infected individuals autopsied by the Manhattan HIV Brain Bank. Subject A presented to study at 52 years, already dependent in instrumental activities of daily living (ADLs), with severe cognitive impairment inclusive of learning and memory dysfunction. Her history was significant for educational disability and head trauma. She had rapid cognitive decline and, by death at age 59 years, was bed-bound, incontinent, and non-communicative. At autopsy, she exhibited severe AD neuropathologic change (NIA-AA score A3B3C3) and age-related tau astrogliopathy (ARTAG). She was homozygous for APOE ε3/ε3. No HIV DNA was detected in frontal lobe by nested polymerase chain reaction. Subject B was a community dwelling 81-year-old woman who experienced sudden death by pulmonary embolus. Prior to death, she was fully functional, living independently, and managing all ADLs. At autopsy, she displayed moderate amyloid and severe tau AD neuropathologic changes (A2B3C2), ARTAG, and cerebral congophilic angiopathy. She was an APOE ε3/ε4 heterozygote, and HIV DNA, but not RNA, was detected in frontal lobe, despite 20 years of therapy-induced viral suppression. We conclude that in the setting of HIV, AD neuropathology may occur with or without symptomatic cognitive dysfunction; as with seronegative individuals, there are likely to be complex factors in the generation of clinically relevant impairments.

Over the past decade, significant advances have been made in the medical treatment of patients with human immunodeficiency virus type 1 infection, leading to a steady increase in referrals for cardiac surgery. We report the outcome of cardiac surgery recently performed in patients with documented human immunodeficiency virus type 1 infection.
