In a statewide PPCI program in Qatar, we observed a mild reduction in PPCI cases during the SARS-CoV-2 outbreak (16% when compared with the same period in 2019), with a modest increase in D2B time. PPCI can be performed effectively during the SARS-CoV-2 outbreak at very high-volume centers with the adoption of strict infection control measures. With proper training and monitoring, both target D2B and hospital staff safety can be achieved.

The novel coronavirus disease-2019 (COVID-19) spread rapidly around the world and was declared as the second pandemic of the 21

century. The first case was detected in Qatar on February 29, 2020. In order to protect patients and staff in Heart Hospital, the only tertiary cardiac center in Qatar, new measures were implemented to reduce the spread of infection in our hospital.

A 13-bed high dependency isolation unit was allocated to receive cardiac patients with appreciate infection control measures. Another isolation unit was also established in coronary care unit for critical patients. All patients admitted to Heart Hospital were tested for COVID-19 on admission. Patients were transferred out of isolation, if result was negative. Patients with positive results were either transferred to a COVID facility before or after planned cardiac procedure depending on their cardiovascular disease risk.

Six hundred and seven patients were admitted to both the isolation units, most of them were men (89%). Forty-fo infection which can be managed by minimizing social activities.

This study demonstrated the importance of the isolation unit with infection control measures in controlling the transmission of COVID-19 in a hospital setting such as the Heart Hospital. Epidemiological risk factors including recent travel, close contact with suspected or confirmed cases within 14 days or less, living in shared accommodation or living in lockdown area were the main risk factors for spreading COVID-19 infection which can be managed by minimizing social activities.

The COVID-19 pandemic has caused major disruption in the health care deliveries and activities worldwide including hospital admission.

We used hospitals discharged coded data from January 1, 2019 to June 30, 2020 to examine the impact of COVID-19 outbreak on the pattern of cardiovascular admission among Hamad Medical Corporation hospitals in the State of Qatar.

In this retrospective observational study, we documented significant changes in the pattern of cardiovascular admissions in our hospitals. There was a significant reduction in hospitalizations of various subsets of cardiac disease. Admissions for acute myocardial infarction dropped by 31%, acute decompensated dropped by 48%, unstable angina dropped by 79% and arrythmia by 80%. Primary percutaneous coronary intervention procedures declined briefly. However, the total deaths remained the same despite the increase in mortality rate due to reduced admissions number.

We postulate the fear of contracting the disease and the lock-down mentality during COVID-19 outbreak contribute to reduction of cardiovascular admission to our hospital.

Spinocerebellar ataxia type 2 (SCA2) is a neurodegenerative disease presenting with redox imbalance. However, the nature and implications of redox imbalance in SCA2 physiopathology have not been fully understood.

The objective of this study is to assess the redox imbalance and its association with disease severity in SCA2 mutation carriers.

A case-control study was conducted involving molecularly confirmed SCA2 patients, presymptomatic individuals, and healthy controls. Several antioxidant parameters were assessed, including serum thiol concentration and the superoxide dismutase, catalase, and glutathione S-transferase enzymatic activities. Also, several prooxidant parameters were evaluated, including thiobarbituric acid-reactive species and protein carbonyl concentrations. Damage, protective, and OXY scores were computed. Clinical correlates were established.

Significant differences were found between comparison groups for redox markers, including protein carbonyl concentration (

Cardioprotective effects of quercetin (Q) have mostly been evaluated in ischemic heart disease models and attributed to senolysis. We hypothesized that Q could alleviate murine cardiac damage caused by HFD by restoring the myocardial microcirculation. C57BL/6J mice were fed standard chow or HFD for 6 months and then treated with Q (50 mg/kg) or vehicle 5-day biweekly for 10 additional weeks. Left ventricular (LV) cardiac function was studied in vivo using magnetic resonance imaging, and intramyocardial fat deposition, microvascular density, oxidative stress, and senescence were analyzed ex vivo. Additionally, direct angiogenic effects of Q were studied in vitro in HUVECs. HFD increased body weight, heart weight, total cholesterol, and triglyceride levels, whereas Q normalized heart weight and triglycerides. LV ejection fraction was lower in HFD vs. control mice (56.20 ± 15.8% vs. 73.38 ± 5.04%, respectively, P less then 0.05), but improved in HFD + Q mice (67.42 ± 7.50%, P less then 0.05, vs. HFD). Q also prevented cardiac fat accumulation and reduced HFD-induced cardiac fibrosis, cardiomyocyte hypertrophy, oxidative stress, and vascular rarefaction. click here Cardiac senescence was not observed in any group. In vitro, ox-LDL reduced HUVEC tube formation activity, which Q effectively improved. Quercetin may directly induce angiogenesis and decrease myocardial oxidative stress, which might account for its cardioprotective effects in the murine HFD-fed murine heart independently from senolytic activity. Furthermore, its beneficial effects might be partly attributed to a decrease in plasma triglycerides and intramyocardial fat deposition.
