Abstract
European sea bass (Dicentrarchus labrax [Linnaeus, 1758]) is a euryhaline marine migrant fish highly valuable for fisheries and aquaculture. Although juveniles are known to use estuaries and occasionally move to freshwater environments, these freshwater incursions had not been reported for adults. Recently, this behavior was observed in the Tagus River (Portugal) for adults occurring up to 150 km from the river mouth, about 80 km upstream from the tidal influence, suggesting the existence of a freshwater contingent. Fisheries management of sea bass should consider the putative existence of a freshwater contingent.

Abstract
Mangroves act as buffer areas for marine systems, providing a barrier to contamination from continental sources by retaining metal pollutants. This study evaluates metal and semimetal contamination in the water column and sediments of four mangroves located on the volcanic island of São Tomé. Several metals had a widespread distribution, with occasional high concentrations, linked to potential sources of contamination. However, the two smaller mangroves, located in the northern part of the island, tended to have high metal concentrations. Arsenic and chromium concentrations were particularly concerning, particularly if we consider this is an isolated and non-industrialized island. This work highlights the need for further assessments and a better understanding of processes and implications of metal contamination in mangroves. This assumes a particular relevance in areas that have particular geochemical compositions (i.e., volcanic origin) and in developing countries, where people often rely directly and heavily on resources obtained from these ecosystems.

Introduction The current COVID-19 pandemic has led to significant changes in physical and mental health and has become a major challenge for cardiac rehabilitation (CR) programs. CR is an essential component in the treatment of heart failure (HF), as it improves cardiorespiratory fitness and quality of life, as well as reducing hospitalization rates. COVID-19 pandemic increased social isolation, and the CR centers were closed. Center-based CR requires the patient to travel to the hospital, which increases the risk of SARS-CoV-2 infection in this high-risk population. In this context, home-based CR can be an excellent strategy to reduce the physical and mental consequences of the social isolation imposed by the COVID-19 pandemic. Objective To test the effectiveness of a home-based CR program on cardiorespiratory fitness and anxiety and depression levels in individuals with HF during covid-19 pandemic. Methods Forty-two individuals with HF (age: 61.3±12.0; LVEF: 37.5±11.2) were included in this study. The exercise training program consisted in 12 weeks of combined exercise training (2x/week; 60min/day, 60-80% VO2peak), with 4 supervised exercise sessions in the hospital context and the remaining at home. Patients were monitored using a heart rate monitor and weekly phone calls. The following parameters were evaluated: cardiorespiratory fitness through the 6-minute walk test (6MWT) and anxiety and depression levels through the Hospital Anxiety and Depression Scale (HADS). Results After the home-based CR program, there was a significant increase in the 6MWT of 49 meters (95%IC: 38 to 60; p<0.001) and a significant decrease in anxiety levels of -1.12 points (95%CI: - 2.163 to -0.075 p=0.036). No significant changes were found in depression levels (p=0.954). Furthermore, the improvements in cardiorespiratory fitness were significantly associated with the reduction in the levels of anxiety (r= -0.281; p=0.028) and depression (r=: -0.278; p=0.030). Conclusions The home-based CR program was able to improve cardiorespiratory fitness and this improvement was associated with a decrease in anxiety and depression levels in individuals with HF. The results suggest that home-based CR can be an important strategy to minimize the physical and mental impact induced by social isolation imposed by COVID-19 pandemic in HF patients.

Introduction Cardiac rehabilitation (CR) is an evidence-based recommended treatment of heart failure (HF) patients. During the COVID-19 pandemic, the shutdown of CR centers was necessary to limit the infection risk among high-risk patients. The integration of a home-based CR (HBCR) program in CR units can help to improve the delivery of care and improve cardiovascular outcomes of HF patients. Purpose To assess the effectiveness of an HBCR program in HF patients. Methods This is a substudy of the EXercise InTervention in Heart Failure trial (EXIT-HF), which include forty-nine HF patients (preserved and reduced ejection fraction). The HBCR program consisted in 12-week combined exercise program (60%-80% of peak oxygen consumption (VO2 peak)), 2 training sessions per week, for a total of 24 sessions. Patients performed 4 supervised training sessions and the remaining sessions at home. All patients performed a cardiopulmonary exercise test (VO2 peak), the 6-minute-walking test (6MWT), collected blood analysis (plasma NT-proBNP), and answered the Minnesota Living with Heart Failure Questionnaire. Results Forty-two patients (86%) complete at least 80% of prescribed training sessions (age: 61.1±12; FEVE: 37.1±10.8). The HBCR program improve VO2 peak from 18.3 to 20.1ml/kg/min (+1.8 ml/kg/min; 95%IC:1.4 to 2.4; p<0.001) and the walked distance at the 6MWT from 462 to 512 meters (+49 meters; 95%IC: 38 to 60; p<0.001). In addition, overall quality of life was improved (-13 points; 95%IC:-7.8 to -18.5; p<0.001), as well physical (-6.3 points; 95%IC:-3.5 to -9; p<0.001) and emotional dimension of quality of life (-2.8points ; 95%IC: -0.9 to -4.7; p=0.06). No significant change was found in NT-proBNP levels (820±1220 vs 674±903; p=0.285). Conclusions Our results showed that HBCR is feasible and can improve functional capacity and quality of life in HF patients.

Introduction
Transcatheter aortic valve implantation (TAVI) is currently the recommended treatment for aortic stenosis (AS) in high or intermediate-risk or inoperable patients. Balloon-expandable valve (BEV) and self-expanding valve (SEV) are the two major types of transcatheter heart valves (TTHV). Despite major diferences, both designs are recomended, however, there are only limited data available for the comparison of newer generation BEV and SEV.
Purpose
Compare echocardiographic and clinical parameters, during 1 year of follow-up of a balloon-expandable (BS) versus self-expanding (SE) transcatheter aortic valve implantantation, with emphasis on the composite endpoits proposed by uptade Valve Academic Researc Consortium (VARC-2).
Methods
Retrospective, comparative study in patients with symptomatic severe AS with a high operative risk, who implanted BEV or SEV between January 2016 and December 2019. All patients underwent echocardiographic study before an after the procedure (on the day , 6 months and 1 year of follow up), clinical data were collected. The following ecocardiographic parameters were evaluated: transvalvular and prosthetic aortic gradientes and paravalvular leak (PVL).
Results
We studied 106 patients (81 ± 8 years, 60% female) with severe AS (mean gradient of 49 ± 12 mmHg), who were threated with BE or SE transcatheter aortic valve. Comparative analysis between BEV vs SEV, showed: there were no statistically significant in mean transprosthetic gradients (9.5 ± 4.8 vs 10 ±6.2; p = 0.49). There were no statistically significant differences between BE and SE valves in the cumulative incidence of death from any cause (21% vs. 28%; p = 0.49), death from cardiovascular causes (3.3% vs. 0%; p= 0.26), all strokes (1.6% vs. 1.6%; p = 0.85), pacemaker implatation (18% vs. 15% p = 0.79); major bleeding (3.3% vs 6.5%; p = 0.18) and renal injury (1.6% vs. 2.1%: p = 0.67). There were statistically significant differences between BE and SE valves in the cumulative incidence of moderate or severe PVL (5% vs. 23.9%; p = 0.009) and repeat hospitalization (11.6% vs. 28%;p = 0.04). Device sucess was achieved in 97 % for BEV vs 91% for SEV (p = 0,39). The early safety at 30 days was observed in 5% for BVE vs. 4.3% for SVE (p = 0.87). The clinical efficacy after 30 days was achieved in 1,6% for BVE vs. 4.3% for SVE (p = 0.03), with higher incidence of moderate or severe PVL. The composite endpoint valve safety occured in 3,3 % for BVE vs 26% for SVE (p < 0,001), with moderate or severe PVL in 23%.
Conclusion(s): In patients with symptomatic severe aortic stenosis who implanted BEV or SEV transcatheter aortic valve there was a significant improvement in the hemodynamic status. The present study suggests that use of SEV was associated with a higher risk of PVL and repeat hospitalization, with a endpoint clinical efficacy after 30 days (4,3%) and time-related valve safety (26%).

Introduction
Regression of left ventricular mass (LVM) after transcatheter aortic valve implantation (TAVI) is an important parameter of left ventricular reverse remodeling and is associated with less hospitalizations 1year after TAVI. The association between LVM índex (LVMi) at 6 months and outcome 1 year after TAVI is unclear.
Purpose
Evaluate and compare LVMi, before TAVI and 6 months after, and determine the association between LVMi regression and clinical outcomes at 1-year follow-up.
Methods
Retrospective, comparative study in patients with symptomatic severe aortic stenosis with a high operative risk, after TAVI. All patients underwent echocardiographic study before TAVI and 6 months of follow-up, the LVMi (by the Devereux formula) was evaluated. Associations between LVMi regression (percent change between baseline and 6 months after TAVI), rehospitalization rate and death at 1 year of follow-up were examined.
Results
We studied 50 patients, 82% with moderade or severe LVMi before TAVI. Comparative analysis between ecocardiography study before and 6 months after TAVI, showed there was statistically significant decrease in LVMi (150,7 ± 38 g/m2 vs 132 ± 36 g/m2; p = 0.03). LVMi moderate or severe (between 130 and 154 g/m2) at 6 months was associated with biggest hospitalization rate (p = 0,03).Comparative analysis between regression of LVMi (before and 6 months after TAVI) and death, showed: decrease of 5% and 10% in LVMi was independently associated with death at 1 year (p = 0,77 vs p = 0,4).
Conclusions
Patients with severe symptomatic aortic stenosis treated with TAVI who had a significant decrease of LVMi after 6 months of follow-up had lower hospitalization rates, but decrease of LVMi is independently associated with death at 1 year of follow-up.

Abstract
Abstract
Introduction
Resistant hypertension is a major challenge of modern cardiovascular medicine, as it is a puzzling problem without a clear solution. Exercise training clearly reduces blood pressure (BP) and oxidative stress in patients with hypertension, however evidence is limited regarding resistant hypertension.
Purpose
To determine the effect of an aerobic exercise training program in BP, angiotensin II and oxidative stress in patients with resistant hypertension.
Methods
EnRicH is a prospective, two-center, single-blinded, randomized controlled trial with a parallel two-arm group. Sixty patients with resistant hypertension were randomly assigned in a 1:1 ratio to undergo a 12-week aerobic exercise training program (exercise) or usual care (control). The powered primary efficacy measure was 24-hour ambulatory systolic BP change from baseline. Secondary outcome measures included daytime and nighttime ambulatory BP, office BP, cardiorespiratory fitness, and oxidative stress and inflammatory biomarkers: Interferon-gamma (IFN-y), Angiotensin II, vascular endothelial growth factor (VEGF), and superoxide dismutase (SOD).
Results
Fifty-three patients (exercise n=26, control n=27) completed the study. Patients were mainly women (54.7%), with an office BP of 140.7±15.9/84.2±9.4 mm Hg and taking an average of 4.6 antihypertensive medications (median, 5; range, 3 to 7). At baseline, no differences were found between groups for the study outcomes and patient characteristics. Ambulatory systolic BP was reduced −7.1 mm Hg (95% CI, −12.8 to −1.4; P=0.015) in the exercise group (127.4±12.2 to 121.2±12.2, p=0.007) compared to control group (126.1±17.2 to 126.9±15.2, p=514) over 24-hour. In addition, 24-hour ambulatory diastolic BP (−5.1 mm Hg, −7.9 to −2.3, P=0.001), daytime ambulatory systolic (−8.4 mm Hg, −14.3 to −2.5, P=0.006), and diastolic BP (−5.7 mm Hg, −9.0 to −2.4, P=0.001) were also reduced in the exercise group compared to the control group. There were no differences in the change of nighttime ambulatory BP between groups. Cardiorespiratory fitness improved in the exercise group by 14% (4.7 ml.kg-1.min-1, P<0.001), while it remained unchanged in the control group (−0.37 ml.kg-1.min-1, P=0.442). A significant between-group difference in favor of exercise group was found for IFN-y (−4.3 pg/mL, 95% CI: −7.1 to −1.5; P=0.003), Angiotensin II (−157.0 pg/mL, 95% CI: −288.1 to −25.9; P=0.020), VEGF (10.53 pg/mL, 95% CI: 0.60 to 22.54; P=0.035), and SOD (0.35 pg/mL, 95% CI: 0.10 to 0.58; P=0.009).
Conclusions
A 12-week moderate intensity aerobic exercise program reduced ambulatory BP, angiotensin II and oxidative stress in patients with resistant hypertension. The antihypertensive effects of exercise in patients with resistant hypertension may be mediated by positive changes in oxidative stress and inflammatory biomarkers.

Abstract
To further improve the understanding ofin vitrobiological effects of incorporated radionuclides, it is essential to accurately determine cellular absorbed doses. In the case ofβemitters, the cross-dose is a major contribution, and can involve up to millions of cells. Realistic and efficient computational models are needed for that purpose. Conventionally, distances between each cell are calculated and the related dose contributions are cumulated to get the total cross-dose (standard method). In this work, we developed a novel approach for the calculation of the cross-absorbed dose, based on the use of the radial distribution function (rdf)) that describes the spatial properties of the cellular model considered. The dynamic molecular tool LAMMPS was used to create 3D cellular models and computerdfsfor various conditions of cell density, volume size, and configuration type (lattice and randomized geometry). The novel method is suitable for any radionuclide of nuclear medicine. Here, the model was applied for the labeling of cells with18F-FDG used for PET imaging, and first validated by comparison with other reference methods. MeanScrossvalues calculated with the novel approach versus the standard method agreed very well (relative differences less that 0.1%). Implementation of therdf-based approach with LAMMPS allowed to achieved results considerably faster than with the standard method, the computing time decreasing from hours to seconds for 106cells. Therdf-based approach was also faster and easier to accommodate more complex cellular models than the standard and other published methods. Finally, a comparative study of the meanScrossfor different types of configuration was carried out, as a function of the cell density and the volume size, allowing to better understand the impact of the configuration on the cross-absorbed dose.

Introduction
Resistant hypertension is a major health problem due to the increased risk of cardiovascular events and mortality. Physical activity and exercise reduces blood pressure in resistant hypertension and is associated with lower cardiovascular risk and mortality. It is presently recommended that physical activity assessment should be a priority in all visits to health settings
Purpose
This study aims to determine if the Brief Physical Activity Assessment Tool (BPAAT), a 2-question tool to assess physical activity, is a valid instrument to detect inactive patients with resistant hypertension.
Methods
Sixty patients with a diagnosis of resistant hypertension were recruited. Outcome measures included clinical data, blood pressure and daily physical activity. Physical activity was objectively measured over a 7-day period with an accelerometer and subjectively assessed (self-assessment) by the BPAAT. The association between the BPAAT and accelerometry, according to the BPAAT scoring categories, was assessed bythe percentage of agreement, Cohen’s Kappa and sensitivity and specificity.
Results
Patients (33 were male) had a mean age of 59.4 ± 9.1years, were on average overweight (BMI 29.5 ± 4.5 kg/m2) and on an average of 4.5 ± 0.7 antihypertensive medications. Forty-two patients (70%) were classified as insufficiently active by the BPAAT compared to the 38 (63.3%) insufficiently active patients identified by the accelerometry data. Regarding the questionnaire’s specificity and sensitivity, the BPAAT correctly identified 32 [84.2 (73.1 – 95.3) %] of the 38 ‘insufficiently active’ patients and 12 [54.5 (34.3 – 74.7) %] of the 22 ‘sufficiently active’ patients identified by accelerometry. The agreement between BPAAT and accelerometry to identify sufficiently/insufficiently active patients, according to the BPAAT’s cut-off values was fair to moderate (Kappa = 0.403 (0.162 – 0.674), with a percentage of agreement of 73.3%.
Conclusion
The BPAAT, a 2-question tool to assess physical activity, seems to be a valid and fast solution to identify insufficiently active adults with resistant hypertension during routine clinical visits.

Background
Physical activity has been associated with reduced arterial stiffness in patients with hypertension. However, in resistant hypertension, a specific population with an increased risk for target organ damage, cardiovascular morbidity, and mortality, the evidence is sparse.
Purpose
The present study aimed to determine the association between daily physical activity and arterial stiffness in patients with resistant hypertension.
Methods
Fifty-seven patients with resistant hypertension were recruited. Physical activity was objectively assessed during 7 consecutive days with accelerometers. Arterial stiffness was evaluated using carotid-femoral pulse wave velocity (cf-PWV) .
Results
Participants (50.9% men), aged 58.8 ± 9.4 years, were mainly overweight and were taking in average 4.5 antihypertensive medications. The cf-PWV showed an inverse correlation with light-intensity physical activity (r = -0.290, p = 0.029) and total daily physical activity (r = -0.287, p = 0.030). Additionally, cf-PWV tended to be inversely associated with the number of steps per day (r = -0.242, p = 0.069). Patients with higher risk of cardiovascular events (cf-PWV ≥ 10 m/s) tended to spend less time in light-intensity physical activity (324.0 ± 129.4 vs. 380.5 ± 103.1 min/day, p = 0.090) and to perform less total daily physical activity (351.5 ± 141.7 vs. 411.7 ± 109.1 min/day, p = 0.091) than participants with cf-PWV below the risk threshold value.
Conclusions
Higher levels of total physical activity and daily levels of light-intensity were associated to lower arterial stiffness. These results emphasize the importance of physical activity as a nonpharmacological tool for patients with resistant hypertension.

Introduction
Amyloid-like protein aggregates play a decisive role in the pathology of heart failure. Alterations in protein homeostasis, in particular, the clearance of toxic amyloid-like aggregates are emerging therapeutic targets in cardiovascular medicine. The clinical benefits of cardiac rehabilitation and exercise training are widely accepted in heart failure; however, little is known about the potential benefit of exercise training in amyloid-like protein aggregates.
Purpose
To assess the effects of a moderate-intensity exercise training program on amyloid-like protein aggregates levels among patients with heart failure with reduced ejection fraction.
Methods
Eighteen subjects participated in the study; eight patients (age: 66.6 ± 5.9 years; FEVE: 38.4 ± 8.9%) with heart failure with reduced ejection fraction participated in a 3-month exercise training program (2 x 60 min sessions per week of moderate-intensity aerobic and resistance exercise). Ten healthy subjects (age: 68. 4 ± 3.1 years) were recruited to an age-matched reference group. Amyloid-like protein aggregates were assessed before and after 3 months of exercise training. Clinical data, medication, anthropometrics, and cardiorespiratory fitness were also assessed. Thioflavin T (ThT) dye fluorescence was used to quantify the plasma levels of amyloid-like aggregates and the Fourier transform infrared spectroscopy (FTIR) was applied to evaluate the conformation of cross-β-sheet structures characteristic of amyloid protein aggregates.
Results
Exercise program improved cardiorespiratory fitness by 14.0 ± 17.1% (17.4 ± 3.2 to 19.7 ± 2.9 ml/kg/min) and reduced NT-proBNP levels by 16.5% (34.2) (median concentration of 632 pg/mL (720.8) to 517.5 pg/mL (707.0)) in the heart failure patients. A slight decrease of amyloid-like aggregates levels was observed in post-exercise training samples (a reduction of 3.1%); interestingly, after the exercise training program, the heart failure patients showed levels of amyloid-like aggregates similar to the reference group (1132.0 ± 114.2 vs. 1094.8 ± 132.9 a.u.). Additionally, the PLS-R multivariate analysis of the amide I region of the FTIR spectra revealed enrichment of antiparallel β-sheets (1693 cm-1) assigned to amyloid-like oligomers in the samples of heart failure patients before, but not after, the exercise program. Of note, oligomeric species, as intermediates of amyloid assembly, can contribute to the increase of amyloid burden, but also, some have been reported to be highly reactive and toxic to cells, being key elements of amyloid pathogenesis.
Conclusions
Our preliminary results indicate that 3 months of exercise training may have significant effects on amyloid-like oligomers, and start hindering the formation of the larger ThT-positive aggregates among patients with heart failure.

Abstract
OBJECTIVE To analyze component resolved diagnosis to Dermatophagoides pteronyssinus (Der p) in patients with respiratory allergy and its relationship with clinical severity in different geographical areas. METHODS 217 patients (mean age 25.85±12.7 years; 51.16% females) were included, selected from 13 centers in Portugal (5 from North, n=65). All had allergic rhinitis, with or without asthma, and had positive skin prick tests to at least one dust mite. Specific IgE (sIgE) to Der p, Dermatophagoides farinae, Lepidoglyphus destructor, Der p1, Der p 2, Der p 10 and Der p 23 were determined by ImmunoCAP. Statistical analysis (Mann Whitney U test) compared patients with rhinitis vs rhinitis and asthma; mild vsmoderate-to-severe rhinitis; North vs South. RESULTS Prevalence of sensitization was 98.2% to Der p, and 72.4%, 89.4%, 9.7% and 77% to Der p 1, Der p 2, Der p 10 and Der p 23, respectively. Corresponding median sIgE levelswere 8.56, 17.7, 0.01 and 3.95 kUA/L. sIgE to all allergens was higher in patients with moderate-to-severe rhinitis and rhinitis with asthma but not statistically significant (NSS). sIgE to Der p 2 was significantly higher in the South when compared with the North (p=0.0496). CONCLUSIONS sensitization to Der p is the most common in Portugal. Der p 2 had the highest prevalence and median sIgE levels. All sIgE to molecular components were higher in more symptomatic patients (NSS). sIgE to Der p 2 was higher in the South, which may be related to the warmer temperature and/or the larger sample size.

Abstract
This study assesses EF and socioemotional development in 30 MPT children between 4 and 6 years, comparing them with 31 FT children. Working Memory was assessed with Digit Span and Corsi Block, verbal inhibitory control and cognitive flexibility with The Shape School Test, visuomotor inhibition with Go/No-Go and socioemotional development with SDQ for parents. In our study, MPT preschoolers had a poorer working memory, inhibitory control and verbal cognitive flexibility, and more emotional problems compared. Our results suggest that there is no safe gestational age in prematurity, for this reason, EF of preterm children should be evaluated at an early age, so early intervention plans can be implemented, preventing preterm from entering primary education in disadvantage.

Abstract
ObjectivesNaturSafe® (Diamond V, USA) is a Saccharomyces cerevisiae fermentation product developed as an animal feed supplement for the further manufacture of nutritionally balanced feeds for beef cattle. This immune support product (Association of American Feed Control Officials number 96.8, 73.046 and International Feed Name number 7–05–520, 8–08–034) has been specifically formulated to optimize beef cattle health and performance, antibiotic stewardship, and food safety. Research has shown that NaturSafe supports optimal rumen and liver health, overall health and immune function, consistency of feed intake, daily gain, feed conversion, and antibiotic effectiveness. As no research previously has assessed the impacts of this feed ingredient on the quality of meat, the objective of this research was to characterize the effects of feeding NaturSafe on meat quality characteristics in beef.Materials and MethodsCrossbred steers (N = 60, n = 12 per treatment; mean hot carcass weight = 421 kg), through an antibiotic free production system, were individually fed diets containing 12, 15, or 18 g/d of NaturSafe or a control diet without (–AB) antibiotics or a control with antibiotics (+AB; 330 mg monensin + 110 mg tylosin·steer–1·d–1) for 112 d. Strip loins were collected and aged for 13 or 29 d postmortem prior to fabrication. Steaks (m. Longissimus) were then evaluated for Warner-Bratzler shear force, pH, sarcoplasmic calcium concentration, troponin-T degradation, fatty acid profile, proximate composition, sarcomere length, total collagen and insoluble collagen. After each aging period, steaks were evaluated for lipid oxidation, and color characteristics (L*, a*, b*, discoloration percentage, and percentage surface oxymyoglobin, metmyoglobin and deoxymyoglobin), during and/or after a 7 d simulated retail display period. A subset of samples at various aging and retail display periods were analyzed for lactic acid bacteria (LAB), psychotrophic plate counts (PPC), and aerobic plate counts (APC). Animal was considered the experimental unit and hot carcass weight and marbling score were used as covariates in the analysis.ResultsTreatment had no effect on pH, sarcomere length, troponin-T degradation, fatty acid profile, proximate composition, total collagen, insoluble collagen, LAB, PPC, APC, lipid oxidation, oxymyoglobin percentage, or metmyoglobin percentage. Meat from cattle fed 18 g/d of NaturSafe was (1) equal to–AB controls and had higher shear force values compared to all other treatments (P < 0.01), (2) had higher (P < 0.05) sarcoplasmic calcium levels than +AB controls and cattle fed 12 g of NaturSafe/d, (3) was redder (higher a* values, P < 0.05) than all other treatments, and (4) was yellower (higher b* values, P < 0.01) than the 12 or 15 g dose and the–AB control. There were no differences among treatments fed NaturSafe for lightness (L*) at either aging time. There were no differences for meat from animals fed 12 or 15 g NatureSafe/d, except deoxymyoglobin percent and discoloration, which were both minimal. Discoloration values were low for all treatments (< 10%).ConclusionThese data indicate that feeding NaturSafe had few discernible effects on meat quality characteristics.

Abstract
ObjectivesMeat color is the number one factor influencing consumer purchase decisions. The emerging market of frozen meat emphasizes the need to understand beef surface discoloration and the ideal parameters of freezing beef to retain a superior color. Therefore, the objectives of this study were to determine the impacts of oxygenation level and frozen storage duration on frozen beef color.Materials and MethodsUSDA Choice strip loins (n = 36) were aged for 4 d or 20 d. Steaks were randomly assigned to a myoglobin state [deoxymyoglobin (DeOxy; immediately packaged), low oxygenation (LoOxy; oxygenated in air for 30 min), and high oxygenation (HiOxy; packaged for 24 h in 80% O2)]. Steaks were then vacuum packaged in oxygen permeable or impermeable film and immediately frozen (–20°C). Following either 0, 2, 4, or 6 mo of frozen storage, steaks were removed from the packaging and immediately analyzed for instrumental color (L*, a*, b*), delta E (magnitude of difference in the L*, a*, b* color space), subjective discoloration, lipid oxidation (via thiobarbituric acid reactive substances- TBARS), oxygen penetration, percent oxymyoglobin, metmyoglobin, and deoxymyoglobin (via spectrometer), and redness (calculated as 630nm/530nm). Data were analyzed using PROC Glimmix procedure in SAS as a split-split-plot with an incomplete block and a 2 × 3 factorial.ResultsHiOxy steaks had greater oxygen penetration and the highest a* values compared to DeOxy and LoOxy steaks regardless of packaging (P < 0.0005). Conversely, DeOxy steaks exhibited the lowest oxygen penetration and a* values regardless of film (P < 0.0005). HiOxy steaks at 4 d had higher a* values than DeOxy and LoOxy at all storage times (P = 0.0118). HiOxy steaks had the highest delta E values compared to DeOxy and LoOxy in permeable packaging and with increasing storage time an increase in delta E for the HiOxy steaks was observed (P = 0.0010).Redness and percent oxymyoglobin were highest for HiOxy steaks within each storage period (P < 0.0002). HiOxy and LoOxy steaks were similar in percent oxymyoglobin when in permeable packaging film. HiOxy steaks had the highest percent oxymyoglobin and DeOxy had the lowest percent oxymyoglobin within each aging and storage period (P < 0.01). Conversely, DeOxy steaks had the highest percent metmyoglobin and HiOxy had the lowest percent metmyoglobin when packaged in impermeable film (P < 0.0001). Lowest percent metmyoglobin values were from the 4 d HiOxy steaks at 2, 4, and 6 mo of storage (P = 0.0188).The HiOxy 20 d steaks had the highest discoloration compared to 4 d aging and more discoloration than all other myoglobin treatments at 6 mo of storage (P < 0.0001). Lipid oxidation increased with storage time (P = 0.0169). HiOxy 20 d aged steaks exhibited the highest TBARS values at 2, 4, and 6 mo (P = 0.0224). HiOxy and LoOxy were similar in discoloration and lipid oxidation except with the HiOxy 20 d (which were less desirable).ConclusionHiOxy steaks exhibit a brighter and deeper cherry red color compared to the DeOxy steaks. HiOxy steaks were superior or similar when compared to LoOxy steaks but displayed more detrimental effects when frozen storage was extended. Based on the results, HiOxy steaks aged for 4 d give a superior red color for extended storage with few unfavorable effects. However, it is not advised to freeze deoxygenated steaks and expect a cherry red color through frozen storage.

Abstract
Abstract
Background
Life expectancy of people living with HIV (PLHIV) has been increasing since the advent of antiretroviral therapy. However, prevalence of non-communicable diseases (NCD) and associated deaths has followed the same trend. From these NCDs, those of cardiovascular origin have become the most prevalent among PLHIV.
Purpose
In this study we delineate a cascade of care for hypertension screening, diagnosis, treatment, drug adherence and control in PLHIV.
Methods
Male and female patients diagnosed with HIV above 40 years of age attending to an outpatient clinic of a reference tertiary care centre for infectious diseases were cross-sectionally screened for hypertension through blood pressure (BP) measurement during outpatient consultation.
Results
A total of 298 subject were enrolled. Of these, 107 (35.9%) presented elevated BP consistent with hypertension according to national guidelines. Of these, only 36 (33.6%) were aware of the diagnosis, 19 (17.7%) were on regular cardiological follow-up, 17 (15.8%) were under treatment and 11 (10.2%) responded to be adherent to BP lowering medication.
Care Cascade HIV_HTN
Conclusions
Steep decline was revealed in several steps of the cascade of care, especially regarding the awareness level. Integrative methods for NCD and HIV care are urgently needed. Early screening of hypertension, diagnosis, treatment, adherence and ongoing BP control should be equal targets in HIV care. Finally, there is an urgent need to encourage HIV primary care and infectious disease health professionals to early screen for cardiovascular outcomes.

Abstract
Cytotoxic drugs applied in chemotherapy enter the aquatic environment after patient's metabolism and excretion, in both main compounds and their respective metabolites. The increased consumption and discharge of these drugs raise concern on the genotoxic burden to non-target aquatic species, due to their unselective action on DNA. Settlement and adsorption of cytotoxic drugs to aquatic sediments pose risks to benthic species through chronic exposure. The aim of the present study was to assess the effects induced by the anticancer drug cyclophosphamide (CP) on the polychaete Nereis diversicolor, after 14 days of exposure to environmental relevant concentrations (10, 100, 500 and 1000 ng L-1). Burrowing impairment, neurotoxicity (Acetylcholinesterase - AChE activity), oxidative stress (superoxide dismutase - SOD; catalase - CAT; glutathione peroxidases - GPXs activities), biotransformation (glutathione-S-transferases - GST), oxidative damage (lipid peroxidation - LPO) and genotoxicity (DNA damage) were assessed. Burrowing impairments were higher at the lowest CP concentrations tested. The higher CP levels tested (500 and 1000 ng L-1) induced a significant inhibition on the enzymatic antioxidant system (SOD, GPx) and on GST activity. DNA damage was also significant at these concentrations as an outcome of CP metabolism, and high levels of oxidative damage occurred. The results showed that the prodrug CP was metabolically activated in the benthic biological model N. diversicolor. In addition to the potential cytotoxic impact likely to be caused in aquatic species with similar metabolism, N. diversicolor proved to be reliable and vulnerable to the cytotoxic mode of action of CP, even at the lower doses.

Abstract
Técnicas de geoprocessamento foram realizadas para a caracterização morfométrica da microbacia do Ribeirão Alto Água Fria – Bofete (SP) pelo Sistema de Informação Geográfica, visando à preservação, racionalização do seu uso e recuperação ambiental. A microbacia apresenta uma área de 4012,17 ha e está localizada entre as coordenadas geográficas: 22o 57’ 41” a 23o 02’ 42” S e 48o 11’ 29” a 48o 20’ 09” WGR. A base cartográfica utilizada foi a carta planialtimétrica de Bofete (SP) para extração das curvas de nível e hidrografia, para determinação dos índices morfométricos. Os resultados apresentaram que os baixos valores da densidade de drenagem, associados à presença de rochas permeáveis, facilitam a infiltração da água no solo, diminuindo o escoamento superficial e o risco de erosão e da degradação ambiental. Os baixos valores do fator de forma e do índice de circularidade indica que a microbacia tende a ser mais alongada com menor susceptibilidade à ocorrência de enchentes mais acentuadas. O parâmetro ambiental, coeficiente de rugosidade, permitiu classificar a microbacia para vocação com agricultura.

Abstract
OBJECTIVE To assess the effects of an exercise-based cardiac rehabilitation programme on daily physical activity levels of patients following myocardial infarction. DESIGN Subanalysis of two randomised, prospective controlled trials. SETTING Outpatient clinic of a secondary hospital. PARTICIPANTS Fifty consecutive patients randomised to the exercise group {n=25; 23 males; mean age 54 [standard deviation (SD) 9] years} or the control group [n=25; 20 males; mean age 58 (SD 9) years]. INTERVENTIONS The exercise group participated in an 8-week aerobic exercise programme plus usual medical care and follow-up. The control group received usual medical care and follow-up. MAIN OUTCOME MEASURES The primary outcome measure was change in time spent undertaking moderate-to-vigorous physical activity per day, assessed by accelerometer over 7 consecutive days. Secondary outcome measures were cardiorespiratory fitness, body mass, and resting blood pressure and heart rate. RESULTS Moderate-to-vigorous physical activity levels increased significantly in the exercise group [43.2 (SD 36.3) to 53.5 (SD 31.9) minutes/day, P=0.030], and remained unchanged in the control group [40.8 (SD 26.2) to 36.8 (SD 26.5) minutes/day, P=0.241] from baseline to the end of the programme. Cardiorespiratory fitness increased significantly in the exercise group (mean difference 2.8; 95% of the difference 1.3 to 4.4ml/kg/minute, P=0.001) after the 8-week programme. CONCLUSIONS In patients under optimal medication following myocardial infarction, participation in an 8-week exercise-based cardiac rehabilitation programme was found to improve physical activity levels consistent with health-related benefits. Future studies are needed to determine whether the increase in physical activity is maintained in the long term.

Abstract
O experimento foi conduzido com o objetivo de determinar a composição química do farelo de mandioca, sua energia metabolizável aparente e verdadeira corrigidas e os coeficientes de metabolização da matéria seca, proteína bruta e energia para frangos de crescimento lento. No experimento foram utilizados 352 frangos em diferentes idades, distribuídos aleatoriamente em três tratamentos com seis repetições compostas pelas rações referências (RRs) formuladas para três diferentes idades e as rações teste (60 % da RRs mais 40 % do farelo de mandioca). O método utilizado foi a coleta total de excretas. Para todas as variáveis estudadas houve um aumento da utilização da energia, matéria seca e proteína bruta das aves com o avanço da idade das mesmas. A composição química do farelo de mandioca apresenta grande variação quando comparados aos valores encontrados na literatura, o que pode interferir de sobremaneira nos valores de energia metabolizável encontrados para este alimento. Nas formulações de rações para frangos de crescimento lento utilizando o farelo de mandioca em sua composição deve-se levar em consideração a idade do animal, visto que com o avanço da idade há melhoria quanto à utilização da energia e da proteína bruta pelas aves. No tocante aos coeficientes de metabolização da matéria seca, proteína bruta e das energias obtidos neste estudo, estes são relativamente altos, indicando que o farelo de mandioca pode ser um alimento com potencial no uso para frangos de crescimento lento e na avicultura alternativa.

Abstract
Built around exercise training, pulmonary rehabilitation (PR) is a multidisciplinary, evidence-based, comprehensive approach to working with the patient as a whole and not just the pulmonary component of the disease. Integrated into the individualized treatment, this intervention aims to reduce symptoms, optimize functional status, increase participation in daily life, and reduce health care costs through stabilizing or reversing systemic manifestations of the disease. Although there are many other components that should be considered to manage the impairment and symptom burden, supervised exercise training is considered the cornerstone of effective pulmonary rehabilitation. This paper addresses our clinical experience at Institut universitaire de cardiologie et de pneumologie de Québec to assess and manage exercise training in line with the current recommendations and guidelines surrounding PR.

Abstract
β1-adrenergic receptors (ADRB1) and Gαs proteins (GNAS) play important roles in the regulation of cardiac function. The present study sought to investigate whether ADRB1 Arg389Gly (rs1801253), GNAS -1211 G/A (rs6123837) and GNAS 2291 C/T (rs6026584) variants are associated with left ventricular function and exercise tolerance in heart failure patients. 61 heart failure patients completed a 6-month exercise-training programme. Left ventricular ejection fraction (LVEF), mitral inflow velocities (deceleration time, and E/A ratio) and exercise tolerance (METs) were assessed at baseline and following exercise training. There were no associations between the studied variants and LVEF or E/A ratio measured at baseline and after exercise training. Deceleration time of early mitral flow was higher at baseline in GNAS -1211G allele carriers compared with -1211A allele homozygotes (P<0.05). Exercise training attenuated deceleration time in -1211G allele carriers (P<0.05) but not in -1211A allele homozygotes. Moreover, ADRB1 389Gly homozygotes had a greater training-induced increase in exercise tolerance than 389Arg homozygotes (P=0.04). This study shows that the functional GNAS -1121 G/A polymorphism is associated with diastolic function at baseline and in response to exercise training in heart failure patients. Furthermore, our data suggest that ADRB1 Arg389Gly polymorphism may influence exercise tolerance.

Abstract
This study aimed to examine the acute effects of cryotherapy on knee position sense and to determine the time period necessary to normalize joint position sense when exercising after cryotherapy. 12 subjects visited the laboratory twice, once for cryotherapy followed by 30 min of exercise on a cycloergometer and once for cryotherapy followed by 30 min of rest. Sessions were randomly determined and separated by 48 h. Cryotherapy was applied in the form of ice bag, filled with 1 kg of crushed ice, for 20 min. Knee position sense was measured at baseline, after cryotherapy and every 5 min after cryotherapy removal until a total of 30 min. The main effect of cryotherapy was significant showing an increase in absolute (F7,154=43.76, p<0.001) and relative (F7,154=7.97, p<0.001) errors after cryotherapy. The intervention after cryotherapy (rest vs. exercise) revealed a significant main effect only for absolute error (F7,154=4.05, p<0.001), i.e., when subjects exercised after cryotherapy, the proprioceptive acuity reached the baseline values faster (10 min vs. 15 min). Our results indicated that the deleterious effect of cryotherapy on proprioception is mitigated by low intensity exercise, being the time necessary to normalize knee position sense reduced from 15 to 10 min.
