We validate the simulation results with the real data by matching the basic and effective reproduction numbers during different phases of the spread. We also simulate different possibilities of the slow lifting of the lockdown by varying the transmission rate as facilities are slowly opened but people follow prevention measures like wearing masks etc. We make predictions on the probability and intensity of a second wave of infection in each of these scenarios.The sudden COVID-19 pandemic has caused a serious global concern due to infections and mortality rates. It is a hazardous disease that has recently become the biggest crisis in the modern era. Due to the limitation of test kits and the need for screening and rapid diagnosis of patients, it is essential to perform a self-operating detection model as a fast recognition system to detect COVID-19 infection and prevent the spread among the people. In this paper, we propose a novel technique called Fast COVID-19 Detector (FCOD) to have a fast detection of COVID-19 using X-ray images. The FCOD is a deep learning model based on the Inception architecture that uses 17 depthwise separable convolution layers to detect COVID-19. Depthwise separable convolution layers decrease the computation costs, time, and they can have a reducing role in the number of parameters compared to the standard convolution layers. To evaluate FCOD, we used covid-chestxray-dataset, which contains 940 publicly available typical chest X-ray images. Our results show that FCOD can provide accuracy, F1-score, and AUC of 96%, 96%, and 0.95%, respectively in classifying COVID-19 during 0.014 s for each case. The proposed model can be employed as a supportive decision-making system to assist radiologists in clinics and hospitals to screen patients immediately.
Vector flow mapping is an emerging echocardiographic method allowing for investigation of intracardiac blood flow mechanics, wall shear stress (WSS), and energy loss (EL). We hypothesized that alterations in EL and WSS will differ among subjects with hypertrophic (HCM), dilated (DCM) cardiomyopathy, and normal controls.

Echocardiograms were prospectively performed with the ProSound F75CV (Hitachi HealthCare., Tokyo, Japan) on all subjects. 2D color Doppler cine loop images were obtained from apical 5 and the apical long axis views and stored digitally. Measurements were averaged over three cardiac cycles using VFM software to derive flow patterns, WSS, and EL. Standard left ventricular (LV) systolic and diastolic functional parameters were also obtained.

A total of 85 subjects, 22 with HCM (age 18±9 yrs.), 18 DCM (age 18±9 yrs.), and 45 age and gender matched controls were included in the study. Diastolic wall shear stress was found significantly different in HCM (0.004±0.185N/m
) compared with DCM (0.397±0.301N/m
, P<0.001), and controls (0.175±0.255N/m
, P=0.027). Furthermore, indexed systolic EL was found to be significantly elevated in HCM (13.91±13.17mW/m
/m
) compared with DCM (8.17±9.77mW/m
/m
, P<0.001), but not controls (6.45±7.47mW/m
/m
).

Differences in abnormal ventricular mechanics observed in HCM and DCM are reflected in both EL and WSS, and are suggestive that changes in energetic parameters may represent novel indices of ventricular dysfunction.

Vascular endothelial dysfunction is an underlying pathophysiological feature of chronic heart failure (CHF). Endothelial progenitor cells (EPCs) are also impaired. The purpose of the study was to assess the effect of a cardiac rehabilitation (CR) program on the increase of EPCs at rest and on the acute response after maximal exercise in patients with CHF and investigate whether there were differences between two exercise training protocols and patients of NYHA II and III classes.

Forty-four patients with stable CHF enrolled in a 36-session CR program and were randomized in one training protocol; either high-intensity interval training (HIIT) or HIIT combined with muscle strength (COM). All patients underwent maximum cardiopulmonary exercise testing (CPET) before and after the CR program and venous blood was drawn before and after each CPET. Five endothelial cellular populations, expressed as cells/10
enucleated cells, were quantified by flow cytometry.

An increase in all endothelial cellular populations at rest was observed after the CR program (p<0.01). The acute response after maximum exercise increased in 4 out of 5 endothelial cellular populations after rehabilitation. Although there was increase in EPCs at rest and the acute response after rehabilitation in each exercise training group and each NYHA class, there were no differences between HIIT and COM groups or NYHA II and NYHA III classes (p>0.05).

A 36-session CR program increases the acute response after maximum CPET and stimulates the long-term mobilization of EPCs at rest in patients with CHF. These benefits seem to be similar between HIIT and COM exercise training protocols and between patients of different functional classes.

A biomarker of fibrin formation, the soluble fibrin monomer complex (SFMC), is abnormally elevated in a variety of clinical situations of hypercoagulability. The aim of the present study was to examine the prognostic impact of SFMC, with regard to increased risk of major cardio- and cerebrovascular events (MACCE) and all-cause mortality, on patients with heart failure (HF).

We conducted a prospective observational study where we analyzed data of 723 hospitalized patients with decompensated HF who were discharged alive and whose SFMC had been measured in a stable condition prior to discharge. The patients were divided into tertiles based on SFMC levels the first (SFMC<1.7μg/ml, n=250), second (≤1.8 SFMC<2.9μg/ml, n=233), and third (3.0μg/ml≤SFMC, n=240) tertiles. The prevalence of chronic kidney disease and anemia was significantly higher in the third tertile than in the first and second tertiles. In contrast, age, sex, CHADS
-Vasc score, left ventricular ejection fraction, and prevalence of hypertension, diabetes and atrial fibrillation did not differ among the tertiles. In the Kaplan-Meier analysis, accumulated event rates of both MACCE and all-cause mortality progressively increased from the first to third tertiles (log-rank P<0.05, respectively). In the multivariate Cox proportional hazard analysis, the third tertile was found to be an independent predictor of MACCE (HR 2.014, P=0.046) and all-cause mortality (HR 1.792, P=0.036).

SFMC is an independent predictor of adverse prognosis in patients with HF.

Left atrial (LA) remodelling is a common feature of many cardiovascular pathologies and is a sensitive marker of adverse cardiovascular outcomes. read more The aim of this study was to establish normal ranges for LA parameters derived from coronary computed tomographic angiography (CCTA) imaging using a standardised image processing pipeline to establish normal ranges in a previously described cohort.

CCTA imaging from 193 subjects recruited to the Budapest GLOBAL twin study was analysed. Indexed LA cavity volume (LACV
), LA surface area (LASA
), wall thickness and LA tissue volume (LATV
) were calculated. Wall thickness maps were combined into an atlas. Indexed LA parameters were compared with clinical variables to identify early markers of pathological remodelling.

LACV
is similar between sexes (31ml/m
v 30ml/m
) and increased in hypertension (33ml/m
v 29ml/m
, p=0.009). LASA
is greater in females than males (47.8ml/m
v 45.8ml/m
male, p=0.031). Median LAWT was 1.45mm. LAWT was lowest at the infwere not associated with detectable changes in LAWT.Clinical trial registrationhttp//www.ClinicalTrials.gov/NCT01738828.
Radial approach for coronary angioplasty is accepted by many specialists in medical centers around the world. The use of radial access is associated with fewer vascular complications and the same success rate in comparison with traditional femoral access. Radial artery spasm is one of the main concerns in this method. The small size of the radial artery and high density of alpha-1 adrenergic receptors in this artery can accelerate the spasm. The objects of this study were to evaluate whether the combined topical gel of lidocaine-verapamil-nitroglycerin could dilate the radial artery and reduce patient pain and sympathetic response during radial puncture.

Patients undergoing elective trans-radial angioplasty were randomized to either placebo or therapeutic gel group in single-center, double-blind study. Placebo or therapeutic gel applied 1cm proximal to the radial styloid process. Radial artery size was measured by ultrasound. Radial pain was reported by the visual analog scale (VAS) and the sympathetic reof verapamil-nitroglycerin-lidocaine significantly increases the size of the radial artery and effectively reduces the radial pain during radial puncture in patients undergoing trans-radial angioplasty.
Cognitive screening is limited by clinician time and variability in administration and scoring. We therefore developed Self-Administered Tasks Uncovering Risk of Neurodegeneration (SATURN), a free, public-domain, self-administered, and automatically scored cognitive screening test, and validated it on inexpensive (<$100) computer tablets.

SATURN is a 30-point test including orientation, word recall, and math items adapted from the Saint Louis University Mental Status test, modified versions of the Stroop and Trails tasks, and other assessments of visuospatial function and memory. English-speaking neurology clinic patients and their partners 50 to 89 years of age were given SATURN, the Montreal Cognitive Assessment (MoCA), and a brief survey about test preferences. For patients recruited from dementia clinics (n = 23), clinical status was quantified with the Clinical Dementia Rating (CDR) scale. Care partners (n = 37) were assigned CDR = 0.

SATURN and MoCA scores were highly correlated (
< .00001;
= 0.90). CDR sum-of-boxes scores were well-correlated with both tests (
< .00001) (
= -0.83 and -0.86, respectively). Statistically, neither test was superior. Most participants (83%) reported that SATURN was easy to use, and most either preferred SATURN over the MoCA (47%) or had no preference (32%).

Performance on SATURN-a fully self-administered and freely available (https//doi.org/10.5061/dryad.02v6wwpzr) cognitive screening test-is well-correlated with MoCA and CDR scores.

We examined associations between nutritional biomarkers and clinical progression in individuals with subjective cognitive decline (SCD), mild cognitive impairment (MCI), and Alzheimer's disease (AD)-type dementia.

We included 528 individuals (64 ± 8 years, 46% F, follow-up 2.1 ± 0.87 years) with SCD (n = 204), MCI (n = 130), and AD (n = 194). Baseline levels of cholesterol, triglycerides, glucose, homocysteine, folate, vitamin A, B12, E and uridine were measured in blood and S-adenosylmethionine and S-adenosylhomocysteine in cerebrospinal fluid. We determined associations between nutritional biomarkers and clinical progression using Cox proportional hazard models.

Twenty-two (11%) patients with SCD, 45 (35%) patients with MCI, and 100 (52%) patients with AD showed clinical progression. In SCD, higher levels of low-density lipoprotein (LDL) cholesterol were associated with progression (hazard ratio [HR] [95% confidence interval (CI)] 1.88 [1.04 to 3.41]). In AD, lower uridine levels were associated with progression (0.
