Short-term outcomes following total correction of tetralogy of fallot in adult patients.

Objectives: Tetralogy of Fallot (TOF) is a common congenital heart disease which should be corrected. The recommended time for the Tetralogy of Fallot Total Correction (TFTC) surgery is during the infancy for the possible difficulties during the surgery and the related issues. However, sometimes TOF is diagnosed and managed during the adulthood.

Misdiagnosis of a Cardiac Angiosarcoma During the COVID-19 Pandemic.

The final months of 2019 saw the emergence of a new pandemic termed "COVID-19". Since then, this infection and its complications have been the priority of healthcare providers, with many symptoms attributed to its early and late presentations. Thus far, other diseases, even fatal situations, have been overlooked or misdiagnosed due to the attribution of patient symptoms to the presence of COVID-19 infection.

The Pragmatic Role of COVID-19 on the Thrombus Grade of Patients with Contemporary ST-Segment-Elevation Myocardial Infarction.

Background: Limited data exist on the clinical outcomes of patients with coronavirus disease 2019 (COVID-19) presenting with ST-segment-elevation myocardial infarction (STEMI).

Methods: This multicenter study, conducted in 6 centers in Iran, aimed to compare baseline clinical and procedural data between a case group, comprising STEMI patients with COVID-19, and a control group, comprising STEMI patients before the COVID-19 pandemic, and to determine in-hospital infarct-related artery thrombus grades and major adverse cardio-cerebrovascular events (MACCEs), defined as a composite of deaths from any cause (cardiovascular and noncardiovascular), nonfatal strokes, and stent thrombosis.

Results: No significant differences were observed between the 2 groups regarding baseline characteristics.

The Epidemiological Characteristics and Outcome of COVID-19 in Patients Undergoing Peritoneal Dialysis: A Multi-center Study in Iran.

The pandemic of COVID-19 emerged in December 2019. Although numerous features of the illness have been investigated, the impact of disease on those patients with underlying diseases, is still a major problem. The aim of this multicenter, cohort study, was to determine the clinical manifestations of COVID-19 in peritoneal dialysis (PD) patients.

Predictors of readmission in hospitalized heart failure patients.

Heart failure(HF) related hospitalization constitutes a significant proportion of healthcare cost. Unchanging rates of readmission during recent years, shows the importance of addressing this problem. Patients admitted with heart failure diagnosis in our institution during April 2018to August 2018 were selected.

Pericardial tuberculosis with an emphasis on empiric therapy in endemic areas for tuberculosis (a case report).

Pericardial tuberculosis (TB) is rare, but has particularly severe complications and a high mortality rate when not treated. Prompt treatment of pericardial TB is important and can be life-saving. We report a 13-year-old girl with massive pericardial effusion and negative workup for TB, who was empirically treated with an excellent response.

A comparative study on the interaction of cis- and trans-platin with DNA and RNA.

Cis-diamminedichloroplatinum(II) is a frequently used and very effective chemotherapeutic drug for treatment of various malignancies; however, the trans isomer is clinically ineffective. Cis-platin exerts its antitumor activity by binding to DNA via intrastrand cross-links to d(GpG) (dG = deoxyguanosine) and to d(ApG) (dA = deoxyadenosine), interfering with DNA replication and transcription and causing cell death. The trans-diamminedichloroplatinum(II) isomer also binds DNA, but is clinically ineffective.

Curcumin binding to DNA and RNA.

Curcumin, the yellow pigment from the rhizoma of Curcuma longa, is a widely studied phytochemical with a variety of biological activities. The ongoing research and clinical trials have proved that this natural phenolic compound has great and diverse pharmacological potencies. Beside its effective antioxidant, antiinflammatory, and antimicrobial/antiviral properties, curcumin is also considered as a cancer chemopreventive agent.
