Results Baseline BMI was 47.9 ± 7.1 kg/m2 and reduced by 5% and 30% post-diet and post-surgery, respectively. BP decreased only post-diet, without pulse pressure change. However, ncPWV, 6.27 ± 1.35 m/s at baseline, was significantly reduced by 10% and 23% post-diet and post-surgery, respectively, also adjusted for BP changes. The E/A ratio rose from 0.95 ± 0.20 to 1.27 ± 0.31 (p less then 0.005), without change in LV geometry or mass, while heart rate and cardiac output fell substantially. Conclusion Weight loss following diet and bariatric surgery is associated with reduced carotid arterial stiffness and improved LV diastolic function. Diet and bariatric surgery are effective treatments for morbid obesity with its concomitant adverse cardiovascular effects.Theranostics, the practice of systematically integrating diagnostics with treatment, has evolved as a field of medicine. In the context of ultrasound based theranostics, both traditional microbubbles and inorganic nanoparticles have emerged as technologies of clinical interest. Ultrasound induced microbubble cavitation has demonstrated efficacy in a variety of applications, including thrombolysis, tumor ablation, targeted microvascular flow enhancement, and targeted drug and gene delivery. This commentary summarizes the mechanisms and applications of ultrasound-based theranostics in cardiovascular medicine, including its impact in pediatric cardiology. It also provides an overview of ongoing clinical trials for theranostics in cardiovascular medicine.Purpose Hypothyroidism (HT) is associated with accelerated atherosclerosis (AS). The efficacy of traditional strategies of hypothyroid AS remains controversial. Here, we aimed to deepen the understanding of the HT-induced acceleration of AS, to decrease the residual risk of coronary artery disease (CAD) and to find a new therapeutic target. Methods We collected peripheral venous blood samples from 20 patients and divided them into 4 groups, namely, the normal group, the HT group, the CAD group and the HT + CAD group. Then we performed mRNA microarray analysis and bioinformatics analysis to screen the differentially expressed genes and pathways, and we also conducted validations on ApoE knockout mice models and Raw264.7 cell models. Results In short, (1) in the analysis between the CAD group and the HT + CAD group, we found a total of 1218 differentially expressed genes, 11 upregulated pathways and 40 downregulated pathways. (2) We validated that patients with HT and CAD had a significantly decreased expression of MAP3K7 (encoding transforming growth factor-β-activated kinase 1, TAK1) gene than normal subjects. (3) In animal and cell experiments, we found the decreased expression of TAK1 and the reduced phosphorylation of AMP-activated protein kinase (AMPK) under the hypothyroid and atherosclerotic condition. (4) Changes in the expressions of TAK1 may affect the progression of AS. Conclusion Taken together, these data suggest that the accelerated AS in hypothyroid patients may be due to the suppression of TAK1-AMPK pathway in macrophages. This new finding may become a novel therapeutic target in hypothyroid AS.An amendment to this paper has been published and can be accessed via the original article.In the original article, incorrect figures were published with incorrect captions.

To the best of our knowledge, no existing contribution to the literature has attempted to gauge the effectiveness of lockdown measures over time in a longitudinal cross-country perspective. Objectives This paper aims to fill the gap in the literature by assessing, at an international level, the effect of lockdown measures (or the lack of such measures) on the numbers of new infections. Given this policy's expected change in effectiveness over time, we also measure the effect of having a lockdown implemented over a given number of days (from 7 to 20 days). Methods We pursue our objectives by means of a quantitative panel analysis, building a longitudinal dataset with observations from countries all over the world, and estimating the impact of lockdown via feasible generalized least squares fixed effect, random effects, generalized estimating equation, and hierarchical linear models. Results Our results show that lockdown is effective in reducing the number of new cases in the countries that implement it, compared with those countries that do not. This is especially true around 10 days after the implementation of the policy. Its efficacy continues to grow up to 20 days after implementation. Conclusion Results suggest that lockdown is effective in reducing the R0, i.e. the number of people infected by each infected person, and that, unlike what has been suggested in previous analyses, its efficacy continues to hold 20 days after the introduction of the policy.Objective To determine the availability and variability of consumer pricing data for an elective lumbar discectomy in the USA. Methods Hospital representatives were contacted via telephone, hospital websites, and state price-transparency websites. A total of 153 hospitals were contacted via telephone calls under the guise of a patient requesting a self-pay price for elective lumbar discectomy. The same hospitals were then researched for price comparison between those requested by phone and those listed on hospital websites after installment of the price transparency law by the Centers of Medicare and Medicaid Services (CMS) on 1 January 2019. Complete and partial prices were recorded for both datasets when available. Hospitals were grouped based on profit status, teaching status, and geographical region. Statistical analysis compared rates of price availability and mean prices between hospital groups and between datasets. Results Thirty-four (23.0%) of 148 hospitals included in the final analysis were able to provide complete price information via telephone. An additional 70 (47.3%) were able to provide a partial price. A total of four (2.7%) institutions provided a complete price and an additional 65 (43.9%) provided a partial price via website. The mean complete price for microdiscectomy when provided was $27,342.36 (n = 34). When compared to government and non-profit hospitals combined, private hospitals had significantly lower partial-prices. Conclusion A patient seeking to undergo a common surgical procedure in the USA will likely be met with difficulty and few options if motivated by price. A high degree of variability exists among US hospitals in 2018 with regards to availability and comprehensiveness of pricing information.
