Abstract

Background: Achieving healthy vascular aging (HVA) is important for decelerating age-related cardiovascular disease risk. We evaluated the interplay between HVA, cardiorespiratory fitness (CRF), and subclinical atherosclerosis. Methods: We analyzed data on 3,722 men who underwent cardiopulmonary exercise testing in a health examination program. HVA was defined as blood pressure 0 and ≥100 and a mean carotid artery intima-media thickness (CIMT) >75th percentile for each age group as well as >0.8 mm of CIMT. Separate and joint associations of HVA and CRF with subclinical atherosclerosis were evaluated.Results: Each 1 MET increment in CRF was associated with 23% higher odds for having HVA. HVA was associated with lower odds of CAC, but not CIMT. CRF modified the association between HVA and CIMT>0.8 mm (interaction: p=0.01); HVA was associated with lower odds of CIMT>0.8 in fit men with no significant association between HVA and CIMT>0.8 mm in unfit men. Compared with no HVA and being unfit, HVA and being fit was associated with lower odds of subclinical atherosclerosis, but there was no significant association between HVA and being unfit with subclinical atherosclerosis. Conclusion: HVA and higher CRF are each associated with a lower risk of subclinical atherosclerosis in men. Higher CRF is associated with a higher prevalence of HVA and may modify the association between HVA and subclinical atherosclerosis.

Abstract

Purpose Inexperienced physicians frequently have difficulty performing nasal fiberoptic intubation. A pre-inserted tracheal tube of the appropriate length allows an excellent view of the laryngeal opening. The purpose of this study was to determine the ideal length of a pre-inserted tracheal tube for nasal fiberoptic intubation and to investigate if it could be predicted from easily measureable patient parameters. Methods This was an observational study in which data on adult patients (n = 150) requiring nasal intubation were collected and analyzed by stepwise regression. During the pre-anesthesia examination, a right-angled gauge was used to measure the distance from the mid-point of the lateral border of the nares to the tragus of the ear (NT distance) and to the mandibular angle (NM distance). The distance from the tragus to the mandibular angle (TM distance) was also measured. The age, sex, height, and weight of each patient were recorded. After induction of anesthesia, the minimum and maximum lengths of the pre-inserted tracheal tube that provided an excellent view of laryngeal opening during nasal fiberoptic intubation were measured. The optimal length was calculated, and an equation was derived through stepwise regression analysis. Results The optimal length for each patient could be reliably predicted using the equation (distances in cm, weight in kg): optimal length (cm) = 1.952 + 0.051 x height (cm) + 0.354 x NM distance (cm) - 0.011 x weight (kg) (r.sup.2 = 0.460, P < 0.001). Conclusion The optimal length of pre-inserted tracheal tube for nasal fiberoptic intubation can be predicted using a newly developed formula with three patient parameters, namely, height, the NM distance, and weight. Application of this equation in the clinical setting should facilitate nasal fiberoptic intubation., Author(s): Jiwon Lee [sup.1], Jung-Man Lee [sup.2] [sup.3], Jeong Jin Min [sup.1] [sup.4], Chang-Hoon Koo [sup.1], Hyun Jeong Kim [sup.3] Author Affiliations: (1) grid.412484.f, 000000010302820X, Department of Anesthesiology and Pain [...]
