Improving Nutritional Status Was Associated with Decreasing Disease Severity and Shortening of Negative Conversion Time of PCR Test in Non-ICU Patients with COVID-19.

Background: Nutrition is an important prevention in old patients with COVID-19. However, in China, there are few studies on the correlation between nutrition and COVID-19.

Methods: A total of 148 hospitalized COVID-19 (65.

The Severity of Obstructive Sleep Apnea Increases the Risk of Arteriosclerosis.

Background: Obstructive sleep apnea (OSA) is a common disorder worldwide. It is associated with myocardial remodeling and arteriosclerosis in patients with hypertension. Our study investigated the relationship between OSA severity and arteriosclerosis and blood pressure in an Asian population.

Relationship between Arterial Stiffness and Renal Function Determined by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) Equations in a Chinese Cohort Undergoing Health Examination.

Background: The association between arterial stiffness and cardiovascular risk in CKD and ESRD patients is well established. However, the relationship between renal function estimation and properties of large arteries is unclear due to the four different methods used to quantify glomerular filtration. This study investigated the relationship between carotid-femoral pulse wave velocity (c-fPWV), as a measure of arterial stiffness, and accepted metrics of renal function.

Disparate Associations of 24-h Central Aortic and Brachial Cuff Blood Pressure With Hypertension-Mediated Organ Damage and Cardiovascular Risk.

Objective: Aim of this study was to evaluate the associations of non-invasive central aortic and peripheral (brachial) blood pressure (BP) for Hypertension-mediated organ damage (HMOD) and atherosclerotic cardiovascular disease (ASCVD) risk.

Methods: We evaluated associations of HMOD with 24-h ambulatory blood pressure monitoring (ABPM) of central aortic and peripheral BP indices in patients with primary hypertension and presence of several cardiovascular risk factors. BP measurements were performed by means of a non-invasive automated oscillometric device (Mobil-O-Graph).

Tightly focusing terahertz wave using gradient-type slotted grating based on spoof surface plasmons.

The d-d-d-d-d gradient-type spoof surface plasmons (SSP) grating was designed and found to exert an obvious effect on electric field localization. Two gradient-shaped planar ports were added to the bottom of this grating to form a gradient-type slotted SSP grating and achieve tight focusing and local electric field enhancement for a terahertz wave. The size of the focal spot was optimized to 0.

Corneal hydration assessment indicator based on terahertz time domain spectroscopy.

Terahertz technology has shown broad prospects for measuring corneal water content, which is an important parameter of ocular health. Based on terahertz time-domain spectroscopy, a new indicator named characteristic ratio (CR) of the sum of low (0.2-0.

Relationship between body mass index and arterial stiffness in a health assessment Chinese population.

Pulse wave velocity (PWV) is a reliable measurement of arterial stiffness. Our study assesses the association between body mass index (BMI) and brachial-ankle PWV (baPWV) in a healthy cohort and seeks to explain possible mechanisms associated with the obesity paradox.A cross-sectional study was conducted in 578 normal individuals.

Pulse wave velocity is decreased with obesity in an elderly Chinese population.

Obesity is generally considered an undesirable risk factor for cardiovascular disease; however, obese subjects with heart failure paradoxically can have better outcomes than their lean counterparts. This study aimed to investigate this characteristic in an elderly Chinese population. Elderly participants (N = 414, age 77 ± 11 years, 211 males) were recruited from a Chinese community-dwelling elderly population.

Association of Haemodynamic Indices of Central and Peripheral Pressure with Subclinical Target Organ Damage.

Background: Central aortic pressure has often been shown to be more closely associated with markers of vascular function and incidence of cardiovascular events compared to peripheral pressure. However, the potential clinical use of central aortic or peripheral haemodynamic indices as markers of target organ damage (TOD) has not been fully established.

Methods: We evaluated associations of TOD with central aortic and peripheral haemodynamic indices (central aortic [cPP] and peripheral pulse pressure [pPP], central aortic augmentation index, and central and peripheral waveform factor) in 770 hospital inpatients (age 60 ± 10 years, 473 males) with primary hypertension.
