Background and Objectives: Acute Heart Failure (AHF) is a common disease and a cause of high morbidity and mortality, constituting a major health problem. The main purpose of this study was to determine the impact of multiorgan ultrasound in identifying the pulmonary hypertension (PH) in patients admitted due to AHF, predict the evolution of the disease during hospitalization and identify areas of improvement in the care of patients with AHF. Materials and Methods: Patients were evaluated with a standard exam of lung ultrasound, echocardiography, inferior vena cava (IVC) and femoral, renal, hepatic, portal venous Doppler flow patterns at admission and on the day of discharge. Results: Thirty patients were enrolled during November 2021. The mean age was seventy-nine years (Standard Deviation – SD 13,4). Seven patients (23.3%) had a renal function worsening. Regarding ultrasound findings, venous excess ultrasonography score (VExUS) score was calculated at admission and at discharge, surprisingly remaining unchanged or even worsened in most of them (21 patients, 70.0%). The area under the curve for the Lung Score was 83.9% (p = 0.008), obtaining a cutoff value of 10 that showed a sensitivity of 82.6% and a specificity of 71.4% in the identification of intermediate and high PH. It was possible to monitor significant changes between both exams on the lung score (p <0.001), hepatic vein Doppler (p <0.001), portal vein Doppler (p = 0.030), intra-renal vein Doppler (p = 0.025) and VExUS score (p = 0.023), remaining similar the femoral vein Doppler (p = 0.177) and IVC (p = 0.132). Conclusions: Our study results suggest that performing serial multiorgan Point-of-Care ultrasound can help us to better identify high and intermediate probability of PH patients with AHF. Currently proposed multi-organ, venous Doppler scanning protocols, such as the VExUS score, should be further studied in different populations before expanding its use in AHF patients.

The aim of this study was to analyze the relationship between healthy vascular aging (HVA) and the Mediterranean diet alongside other lifestyles in a Spanish population aged 35 to 75 years without previous cardiovascular diseases. Methods: Cross-sectional descriptive study with 501 individuals aged 35 to 75 years recruited from five health centers by random sampling stratified by age and sex (55.90±14.24 years, 49.70% men). HVA was determined in two steps. Step 1: Subjects with vascular damage to the carotid arteries or peripheral arterial disease were classified as non-HVA. Step 2: The study population was classified by age and sex using the percentiles of the vascular aging index (VAI), with VAI ≤p25 considered HVA and >p25 considered non-HVA. The VAI was estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76. Carotid-femoral pulse wave velocity (cfPWV) was measured with the SphygmoCor^® device and carotid intima-media thickness using Sonosite Micromax^® ultrasound. Mediterranean diet (MD) adherence, alcohol and tobacco use were recorded through validated questionnaires. Physical activity was assessed with the ActiGraph-GT3X^® accelerometer. Results: The mean VAI value was 61.23±12.86; (Men 63.47±13.75 and women 59.04±11.54; p<0.001). HVA was found in 18.9% (men 19.9% and women 17.8%). In the multiple regression analysis after adjusting for possible confounding factors, the mean VAI value showed a positive association with alcohol use (β=0.020) and sedentary hours per week (β=0.109), and a negative association with hours of activity per week (β=-0.102) and with the number of healthy lifestyles (β=-0.640). In the logistic regression analysis after adjusting for possible confounding factors, and compared to those classified as non-HVA, subjects classified as HVA were more likely to show adherence to MD (OR = 0.571), perform more than 26 hours per week of physical activity (OR = 1.735), spend less than 142 hours per week being sedentary (OR = 1.696), and have more than two healthy lifestyles (OR = 1.877). Conclusion: The results of this study suggest that the more time spent doing physical activity and the less time spent sitting, the lower the vascular aging index and the greater likelihood of being classified in the group of subjects showing HVA.

The COVID-19 pandemic may have increased interpersonal and intimate violence, harmful use of alcohol and other drugs (AOD), and mental health problems. The present study uses a valid path model to describe relationships between these conditions of young Mexicans during the second year of the pandemic. A sample of 7,420 young Mexicans ages 18 to 24—two-thirds of whom were women—completed the Life Events Checklist, the Alcohol, Smoking, and Substance Involvement Screening Test, the Major-Depressive-Episode Checklist, the Generalized Anxiety Scale, and the Posttraumatic Stress Disorder (PTSD) Checklist. Young Mexicans reported higher rates of victimization and perpetration of interpersonal and intimate violence and mental health symptomatology than those noted pre-pandemic and in the first year of the pandemic. Harmful use of AOD rates were like those reported by adolescents before. Findings suggested asymmetric victimization and perpetration of intimate violence by gender (with women being at a higher risk than men, p≤.05). More men than women engaged in the harmful use of AOD (except for sedatives, which more women abuse). In contrast, more women than men were at risk of all mental health conditions. The path model indicates that being a victim of intimate violence predicts harmful use of tobacco, alcohol, cocaine, and sedatives, depression, anxiety, and specific PTSD symptoms (such as re-experimentation and avoidance symptoms). Being a victim of interpersonal violence resulted in severe PTSD symptoms (including avoidance, negative alterations in cognition-mood, and hyperarousal signs). Harmful use of sedatives predicted depressive symptoms. Men´s victimizing intimate violence model contrasted with that of women, which also included being the victim of interpersonal violence and severe PTSD symptoms. The high school youth model had three paths -victimizing-intimate violence, victimizing-interpersonal abuse, and sedative use, which predicted depression. The findings of this study could serve as the basis for future studies exploring mechanisms that predict violence patterns to develop the most cost-effective preventive programs and public policies and to address mental health conditions during community emergencies.

The study aimed to evaluate the nutritional value of watermelon plant silage (WPS) and to assess the effect of replacing alfalfa hay (AH) with WPS in a diet formulated for dairy goats. The study used four goats as donors of rumen microbiota to analyze in vitro fermentation parameters. The chemical composition analysis revealed that WPS and AH had similar protein content (21.1 vs. 18.9 g CP/100 g DM), but WPS had lower contents of organic matter (77.4 vs. 89.6 g/100 g DM), NDF (36.3 vs. 49.4 g/100 g DM), ADF (26.4 vs. 34.6 g/100 g DM), LAD (6.40 vs. 8.01 g/100 g DM), and amino acids (716 vs. 874 g AA/kg N) compared to AH. Conversely, WPS had higher fat content (3.09 vs. 1.29 g CF/100 g DM) and different macro- and micromineral content values than AH. In a first in vitro experiment, WPS and AH were incubated independently to compare their fermentation behaviour, indicating that the metabolizable energy (ME) tended to be higher for WPS compared to the AH diet (6.67 vs. 5.72 MJ/kg DM; p = 0.058). WPS fermentation produced lower concentrations of total VFA than AH (66.6 vs. 115 mM; p = 0.011), lower proportions of propionate and valerate (p ≤ 0.022), and higher proportions of isobutyrate (p = 0.001), without altering gas production (GP) kinetics as degradation rate and its potential release. In a second in vitro trial, a formulated goat diet (consisting of commercial concentrate and AH in a 1:1 ratio) was used as a control to assay the impact of AH replacing by WPS at 25% and 50% respectively. Trends were observed in several parameters, such as a linear increase in GP rate (p = 0.088), organic matter digestibility (p = 0.067), and CH4 concentration in the gas produced (p = 0.094) as AH was replaced by WPS. The study concluded that WPS could serve as a viable fodder to replace AH in conventional dairy goat diets while simultaneously reducing agricultural waste and serving as a regenerative model for implementing the circular economy strategy in the affected sectors.

Background/Objectives: Cardiovascular diseases are one of the leading causes of morbidity and mortality worldwide. Health-related quality of life is crucial to assess the impact of cardiovascular diseases and to guide therapeutic strategies. The Short Form 36 Health Survey and the RAND 36-Item Health Survey questionnaires are common tools for measuring health-related quality of life in patients with cardiovascular disease, but their reliability may vary according to the population studied. The aim of this study is to compare the reliability of the SF-36 and the RAND-36 in a population with cardiac pathology, addressing the question of which of these instruments offers a more consistent and useful measurement in this specific group. Methods: Cross-sectional observational study carried out at the University Hospital of Burgos (Spain). 413 patients with cardiovascular pathology referred to the Cardiac Rehabilitation Unit were included. Patients with incomplete data or who did not participate in the program were excluded. Internal consistency (Cronbach’s alpha), item-total correlation and reliability and a half-half analysis were performed. Results: Both questionnaires showed similar and adequate reliability for patients with cardiovascular pathology. Internal consistency, as measured by Cronbach’s alpha, was above 0.80 for most dimensions, supporting its robustness. Significant inter-item and inter-dimension correlations were found in both scales, except in some specific cases in the dimension ‘Physical Functioning’. The half-half analysis confirmed the good reliability of both scales. Conclusions: Both the SF-36 and the RAND-36 are highly reliable tools for assessing health-related quality of life in patients with cardiovascular disease. The results may have significant implications for clinical practice, helping in the selection of health-related quality of life monitoring instruments and in the evaluation of the efficacy of therapeutic interventions.
