Background:Diffuse cardiac fibrosis is an important factor in the prognostic assessment of patients with ventricular dysfunction. Cardiovascular magnetic resonance imaging (CMR) native T1 mapping is highly sensitive and considered an independent predictor of all-cause mortality and heart failure (HF) development in patients with cardiomyopathy.Objectives:To evaluate the feasibility of native T1 mapping assessment in patients with HF in a cardiology referral hospital and its association with structural parameters and functional profile.Methods:Cross-sectional study with adult patients with HF NYHA functional classes I and II, ischemic and non-ischemic, followed in a referral hospital, who underwent CMR. Native T1 values were analyzed for structural parameters, comorbidities, etiology, and categorization of HF by left ventricular ejection fraction (LVEF). Analyses were performed with a significance level of 5%.Results:Enrollment of 134 patients. Elevated native T1 values were found in patients with greater dilation (1004.9 vs 1042.7ms, p = 0.001), ventricular volumes (1021.3 vs 1050.3ms, p <0.01) and ventricular dysfunction (1010.1 vs 1053.4ms, p <0.001), also present when the non-ischemic group was analyzed separately. Patients classified as HF with reduced ejection fraction had higher T1 values than those with HF and preserved ejection fraction (HFPEF) (992.7 vs 1054.1ms, p <0.001). Of those with HFPEF, 55.2% had higher T1.Conclusions:CMR T1 mapping is feasible for clinical HF evaluation. There was a direct association between higher native T1 values and lower ejection fraction, and with larger LV diameters and volumes, regardless of the etiology of HF. 相似文献

This study aimed to identify and assess the evidence on the association between idiopathic chronic low back pain (LBP) and cognitive function in individuals with LBP. A secondary aim was to explore whether changes in cognitive function are associated with pain characteristics and psychological factors (eg, catastrophizing and fear of movement). Eleven studies were included in this systematic review, and four meta-analyses were conducted. Low to very low-quality evidence suggests impaired cognitive function in individuals with LBP compared to asymptomatic controls for problem solving (k = 5; d = 0.33; CI = 0.16–0.50; z = 3.85 p = 0.0001), speed of information processing (k = 5; d = 0.44; CI = 0.22–0.65; z = 4.02 p < 0.0001), working memory (k = 6; d = 0.50; CI = 0.34–0.66; z = 6.09 p < 0.0001), and delayed memory (k = 3; d = 0.34; CI = 0.07–0.6, z = 2.49 p = 0.02). The association between LBP intensity and psychological factors and cognitive function was inconclusive. More studies are needed to explore these associations and improve evidence in this field. The results of this study suggest that cognitive aspects should be considered during the rehabilitation process of patients with LBP and raise further questions, including whether individuals with LBP are at a greater risk of developing dementia or whether targeting cognitive function will increase the probability of success of LBP treatment. These questions should, also, be considered in future studies. 相似文献

The SARS-CoV-2 pandemic and subsequent interruption of influenza circulation has lowered population immunity to influenza, especially among children with few prepandemic exposures. Using data from a prospective pediatric cohort study based in Managua, Nicaragua, we compared the incidence and severity of influenza A/H3N2 and influenza B/Victoria between 2022 and two prepandemic seasons. We found a higher incidence of A/H3N2 in older children in 2022 compared with pre-2020 and a higher proportion of severe influenza in 2022, primarily among children aged 0–4, suggesting an influence of the SARS-CoV-2 pandemic on influenza incidence and severity in children. 相似文献
