Previous studies, mainly focused on quantity rather than variety, have shown beneficial associations between the amount of fruit and vegetable consumed, diet quality and healthy lifestyle. The aim is ...to evaluate the association between fruit and vegetable consumption, diet quality and lifestyle in an elderly Mediterranean population, considering both variety and the combination of quantity and variety (QV).
A cross-sectional analysis of 6647 participants (51.6% of males) was conducted in the framework of the PREDIMED-Plus study. A variety score was created as the sum of vegetables and/or fruits consumed at least once per month using food frequency questionnaires. Dietary Reference Intakes (EAR and IA values) were used to estimate the prevalence of inadequate intake of dietary fiber and micronutrients. Logistic regression models were performed to examine the association between fruit and vegetable consumption and not meeting the DRIs, by tertiles of fruit and vegetable variety and QV categories.
Participants with higher fruit and vegetable variety score reported a significant higher intake of fiber, vitamins, minerals and flavonoids and were significantly more likely to be physically active and non-smoker. Besides, higher variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber (0.13 (0.11–0.16), two or more (0.17 (0.14–0.21), three or more (0.15 (0.13–0.18) and four or more (0.11 (0.10–0.14) micronutrients in our participants. Higher quantity and variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber (0.05 (0.04–0.06), two or more (0.08 (0.06–0.10), three or more (0.08 (0.06–0.09) and four or more (0.06 (0.05–0.07) micronutrients.
Greater variety in fruit and vegetable intake was associated with better nutrient adequacy, diet quality and healthier lifestyle in an elderly Mediterranean population.

Introduction: Care and attention to people’s health is an objective of professionals in this area. Comprehensive strategies are being sought to reduce the alarming prevalence of obesity in ...populations around the world, coupled with the restructuring of the health system that came as a consequence of the COVID-19 pandemic, different tools, such as online nutrition counseling, have been incorporated to embrace the needs and provide a service in favor of the population. Objective: To evaluate the effect of online nutrition counseling on anthropometric parameters of overweight and obese adults. Methodology: Thirty individuals were enrolled in an online nutritional intervention and followed a weight control diet for 8 weeks. Every 15 days, the participants received nutritional counseling through virtual platforms. Anthropometric parameters were evaluated at the beginning, middle and end of the intervention, the physical activity performed by the participants was calculated, and an emotional eating questionnaire was applied. Results: Significant changes were observed in baseline versus final anthropometric parameters. 30% of participants reported an increase in the physical activity performed, and 31% indicated improvements in the influence of emotions on their eating habits. Conclusion: Online nutrition counseling is a feasible and reliable strategy to provide and receive nutritional care remotely.
Transcatheter mitral valve repair (TMVR) is an effective therapy for high-risk patients with severe mitral regurgitation (MR) but heart failure (HF) readmissions and death remain substantial on ...mid-term follow-up. Recently, right ventricular (RV) to pulmonary arterial (PA) coupling has emerged as a relevant prognostic predictor in HF. In this study, we aimed to assess the prognostic value of tricuspid annular plane systolic excursion (TAPSE) to PA systolic pressure (PASP) ratio as a non-invasive measure of RV-to-PA coupling in patients undergoing TMVR with MitraClip (Abbott, CA, USA).
Multicentre registry including 228 consecutive patients that underwent successful TMVR with MitraClip. The sample was divided in two groups according to TAPSE/PASP median value: 0.35. The primary combined endpoint encompassed HF readmissions and all-cause mortality.
Mean age was 72.5 ± 11.5 years and 154 (67.5%) patients were male. HF readmissions and all-cause mortality were more frequent in patients with TAPSE/PASP ≤ 0.35: Log-Rank 8.844,
= 0.003. On Cox regression, TAPSE/PASP emerged as a prognostic predictor of the primary combined endpoint, together with STS-Score. TAPSE/PASP was a better prognostic predictor than either TAPSE or PASP separately.
TAPSE/PASP ratio appears as a novel prognostic predictor in patients undergoing MitraClip implantation that might improve risk stratification and candidate selection.
(Hook F.), belonging to the Celastraceae family, is an evergreen shrub, native of the central southern mountains of Chile. Previous studies demonstrated that the total extract of
(MD) has an ...acetylcholinesterase inhibitory activity along with growth regulatory and insecticidal activities. β-Dihydroagarofurans sesquiterpenes are the most active components in the plant. However, its activity in cancer has not been analyzed yet. Here, we demonstrate that MD has a cytotoxic activity on breast (MCF-7), lung (PC9), and prostate (C4-2B) human cancer cells with an IC
(µg/mL) of 40, 4.7, and 5 µg/mL, respectively, an increasing Bax/Bcl2 ratio, and inducing a mitochondrial membrane depolarization. The β-dihydroagarofuran-type sesquiterpene (MD-6), dihydromyricetin (MD-9), and dihydromyricetin-3-O-β-glucoside (MD-10) were isolated as the major compounds from MD extracts. From these compounds, only MD-6 showed cytotoxic activity on MCF-7, PC9, and C4-2B with an IC
of 31.02, 17.58, and 42.19 µM, respectively. Furthermore, the MD-6 increases cell ROS generation, and MD and MD-6 induce a mitochondrial superoxide generation and apoptosis on MCF-7, PC9, and C4-2B, which suggests that the cytotoxic effect of MD is mediated in part by the β-dihydroagarofuran-type that induces apoptosis by a mitochondrial dysfunction.
Zinc-α2 glycoprotein (ZAG) is an adipokine involved in adipocyte metabolism with potential implications in the pathogenesis of metabolic disorders. Our aim was to evaluate the relationship between ...visceral (VAT) and subcutaneous adipose tissue (SAT) ZAG expression and metabolic parameters in patients with class III obesity, along with the impact of basal ZAG expression on short- and medium-term outcomes related to bariatric surgery. 41 patients with class III obesity who underwent bariatric surgery were included in this study. ZAG gene expression was quantified in SAT and VAT. Patients were classified into two groups according to SAT and VAT ZAG percentile. Anthropometric and biochemical variables were obtained before and 15 days, 45 days, and 1 year after surgery. The lower basal SAT ZAG expression percentile was associated with higher weight and waist circumference, while the lower basal VAT ZAG expression percentile was associated with higher weight, waist circumference, insulin, insulin resistance, and the presence of metabolic syndrome. Basal SAT ZAG expression was inversely related to weight loss at 45 days after surgery, whereas no associations were found between basal VAT ZAG expression and weight loss after surgery. Additionally, a negative association was observed between basal SAT and VAT ZAG expression and the decrease of gamma-glutamyl transferase after bariatric surgery. Therefore, lower SAT and VAT ZAG expression levels were associated with an adverse metabolic profile. However, this fact did not seem to confer worse bariatric surgery-related outcomes. Further research is needed to assess the clinical significance of the role of ZAG expression levels in the dynamics of hepatic enzymes after bariatric surgery.
In this work, pristine and Pt-catalyzed SnO2 hybrid structures were designed over porous Si (p-Si) substrates via chemical bath deposition. CO2 gas sensing properties such as sensing response, ...response/ recovery time were studied as a function of different platinum concentrations and compared with the devices prepared over c-Si substrates. TEM analysis confirms the nanometric size of ∼2.5 nm of the Pt nanoparticles. XRD analysis for the hybrid nanostructures confirms the presence of tetragonal structure of SnO2. SEM and EDS analysis of the SnO2 nanostructures confirms the spherical morphology and the composition respectively. Significant sensing response of hybrid nanostructures could be obtained at low operating temperature (∼100 °C). At an optimal concentration of PtNPs, the sensitivity of pSi based hybrid structures increased by a factor of ∼7.5 compared to the ones on crystalline-Si. The higher sensitivity is possibly due to the charge carrier exchange enhancement in the Pt–SnO2 interface in addition to the high surface area provided by p-Si. The increment in the p-Si surface area also led to the higher population of active sites and the charge transfer leads to a more efficient dissociation of adsorbed H2O molecules, which further served as active sites for CO2 detection. The CO2 gas sensing mechanism with respect to different substrate and Pt addition is explained in terms of adsorbed OH− ions reacting with CO2 molecules at the SnO2 surface. The utilization of the proposed hybrid structures with high surface area favors the miniaturization of possible device fabrication for real-life applications.

Summary Background Cryptogenic organizing pneumonia (COP) is a rare disease, and its diagnosis requires histological confirmation. The objective of our study was to describe the findings of the ...thoracic high-resolution computed tomography (HR-CT) and bronchoalveolar lavage (BAL) in patients with confirmed COP and evaluate the complementary diagnostic use of BAL and thoracic HR-CT. Methods Patients recorded in the registry of interstitial pulmonary diseases between 1991 and 2008 were located and the COP patients selected. Results We identified 21 patients with histological confirmation of COP. The median age was 58.0 ± 15.9 years, and 61.9% of patients were female. The most frequent thoracic HR-CT profile was patchy infiltrate (71.4%), followed by parenchymatous consolidation (42.9%). The most frequent BAL profile was mixed alveolitis (62%) with lymphocyte predominance, a CD4/CD8 index of 0.4 and foamy macrophages. The effectiveness of transbronchial biopsy was 66.6%. The diagnostic utility of Poletti’s BAL criteria gives us a specificity of 88.8%, although the sensitivity obtained was low. The specificity of certain HR-CT profiles is 99%. In addition, we observed a complementary use of the HR-CT and the BAL. Conclusions The imaging findings and BAL could be useful for patients with appropriate clinical presentation and for those whose transbronchial biopsy is negative or for whom a confirmatory biopsy cannot be performed.
The aim of this paper is to illustrate an overview of the automatic speech recognition (ASR) module in a spoken dialog system and how it has evolved from the conventional GMM-HMM (Gaussian mixture ...model - hidden Markov model) architecture toward the recent nonlinear DNN-HMM (deep neural network) scheme. GMMs have dominated for a long time the baseline of speech recognition, but in the past years with the resurgence of artificial neural networks (ANNs), the former models have been surpassed in most recognition tasks. An outstanding consideration for ANNs-based acoustic model is the fact that their weights can be adjusted in two training steps: i) initialization of the weights (with or without pre-training) and ii) fine-tuning. To exemplify these frameworks, a case study is realized by using the Kaldi toolkit, employing a mid-vocabulary with a personalized speaker-independent voice corpus on a connected-words phone dialing environment operated for recognition of digit strings and personal name lists in Spanish from Mexico. The obtained results show a reasonable accuracy in the speech recognition performance through the DNN acoustic modeling. A word error rate (WER) of 1.49% for context-dependent DNN-HMM is achieved, providing a 30% relative improvement with regard to the best GMM-HMM result in these experiments (2.12% WER).
