Abstract
BACKGROUND Obesity represents a global health crisis, yet a dichotomy is emerging with classification according to the metabolic state into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO). This study aimed to identify distinctive systemic clinical/endocrinological parameters between MHO individuals, employing a comprehensive comparative analysis of 50 biomarkers. Our emphasis was on routine analytes, ensuring cost-effectiveness for widespread use in diagnosing metabolic health. SUBJECTS/METHODS The study included 182 women diagnosed with obesity referred for bariatric surgery at the Endocrinology, Diabetes, and Metabolism Service of São João Hospital and University Centre in Portugal. MUO was defined by the presence of at least one of the following metabolic disorders: diabetes, hypertension, or dyslipidemia. Patients were stratified based on the diagnosis of these pathologies. RESULTS Significantly divergent health-related parameters were observed between MHO and MUO patients. Notable differences included: albumin (40.1 ± 2.2 vs 40,98 ± 2.6 g/L, p value = 0.017), triglycerides (110.7 ± 51.1 vs 137.57 ± 82.6 mg/dL, p value = 0.008), glucose (99.49 ± 13.0 vs 119.17 ± 38.9 mg/dL, p value < 0.001), glycated hemoglobin (5.58 ± 0.4 vs 6.15 ± 1.0%, p value < 0.001), urea (31.40 ± 10.0 vs 34.61 ± 10.2 mg/dL, p value = 0.014), total calcium (4.64 ± 0.15 vs 4.74 ± 0.17 mEq/L, 1 mEq/L = 1 mg/L, p value < 0.001), ferritin (100.04 ± 129.1 vs 128.55 ± 102.1 ng/mL, p value = 0.005), chloride (104.68 ± 1.5 vs 103.04 ± 2.6 mEq/L, p value < 0.001), prolactin (13.57 ± 6.3 vs 12.47 ± 7.1 ng/mL, p value = 0.041), insulin (20.36 ± 24.4 vs 23.87 ± 19.6 μU/mL, p value = 0.021), c peptide (3.78 ± 1.8 vs 4.28 ± 1.7 ng/mL, p value = 0.003), albumin/creatinine ratio (15.41 ± 31.0 vs 48.12 ± 158.7 mg/g creatinine, p value = 0.015), and whole-body mineral density (1.27 ± 0.1 vs 1.23 ± 0.1 g/cm2, p value = 0.016). CONCLUSIONS Our findings highlight potential additional parameters that should be taken into consideration alongside the commonly used biomarkers for classifying metabolic health in women. These include albumin, urea, total calcium, ferritin, chloride, prolactin, c-peptide, albumin-creatinine ratio, and whole-body mineral density. Moreover, our results also suggest that MHO may represent a transitional phase preceding the development of the MUO phenotype.

Abstract
Chronic stress is a major risk factor for neuropsychiatric conditions such as depression. Adult hippocampal neurogenesis (AHN) has emerged as a promising target to counteract stress-related disorders given the ability of newborn neurons to facilitate endogenous plasticity. Recent data sheds light on the interaction between cannabinoids and neurotrophic factors underlying the regulation of AHN, with important effects on cognitive plasticity and emotional flexibility. Since physical exercise (PE) is known to enhance neurotrophic factor levels, we hypothesised that PE could engage with cannabinoids to influence AHN and that this would result in beneficial effects under stressful conditions. We therefore investigated the actions of modulating cannabinoid type 2 receptors (CB2R), which are devoid of psychotropic effects, in combination with PE in chronically stressed animals. We found that CB2R inhibition, but not CB2R activation, in combination with PE significantly ameliorated stress-evoked emotional changes and cognitive deficits. Importantly, this combined strategy critically shaped stress-induced changes in AHN dynamics, leading to a significant increase in the rates of cell proliferation and differentiation of newborn neurons, overall reduction in neuroinflammation, and increased hippocampal levels of BDNF. Together, these results show that CB2Rs are crucial regulators of the beneficial effects of PE in countering the effects of chronic stress. Our work emphasises the importance of understanding the mechanisms behind the actions of cannabinoids and PE and provides a framework for future therapeutic strategies to treat stress-related disorders that capitalise on lifestyle interventions complemented with endocannabinoid pharmacomodulation.

Abstract
Ultrasound-guided hydrodistention has been established as an effective minimally invasive treatment option for glenohumeral joint adhesive capsulitis (AC). Nonetheless, the long-term outcomes of the procedure have not yet been established. A total of 202 patients with AC were prospectively recruited and followed up for a total of 2 years. Pain and functionality were assessed with the use of the visual analogue scale (VAS) and the disabilities of the arm, shoulder, and hand (DASH) score, respectively, at the beginning and the end of the follow-up period. The relapse of AC over the 2-year period and the effect of diabetes were also evaluated in the treatment cohort. The Mann-Whitney U test was used to compare mean scores at the two time points, and Cox survival analysis and χ2 test were used to assess the effect of diabetes on AC relapse. VAS and DASH scores were significantly lower at 2 years compared with the beginning of the follow-up period (p < 0.001). Diabetes was diagnosed in 38/202 patients (18.8%) and was found to be significantly associated with recurrence of the disease (p < 0.001). In conclusion, in this observational study, we have demonstrated that ultrasound-guided hydrodistention is linked to excellent long-term outcomes for the treatment of AC, which are significantly worse in patients with diabetes.

Abstract
Breast cancer is a heterogeneous entity, where different molecular subtypes (MS) exhibit distinct prognostic and therapeutic responses. A series of 62 breast cancer samples stratified by MS was obtained from the tumor biobank of IPO-Porto. The expression of glycolysis and gluconeogenesis-regulating enzymes was investigated by immunohistochemistry. Data analysis included stratification according to MS, body mass index (BMI), and BMI with MS (mBMI). We observed significant differences in pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PCK), and fructose-1,6-bisphosphatase (FBP) tumor cell expression when stratified by MS and mBMI. The expression of these enzymes was also statistically dependent on hormonal receptors and HER2 status and correlated with pathological stage and histological grade. Obesity tended to attenuate these differences, particularly in PC expression, although these were not affected by adipocyte deposition or inflammatory infiltration at the tumor microenvironment. Nonetheless, PCK and FBP expression was also modified by the presence of obesity-associated disorders like diabetes, hypertension, and dyslipidemia. Taken together, these findings identify metabolic fingerprints for breast cancer as distinct histological types, which are affected by the presence of obesity and obesity-associated conditions. Despite the biological role of the differential expression of enzymes remaining unknown, the current study highlights the need to identify the expression of gluconeogenic-regulating enzymes as a tool for personalized medicine.

Abstract
Obesity is a relevant risk factor in breast cancer (BC), but little is known about the effects of overweight and obesity in surgical outcomes of BC patients. The aim of this study is to analyse surgical options and associated overall survival (OS) in overweight and obese women with BC. In this study, 2143 women diagnosed between 2012 and 2016 at the Portuguese Oncology Institute of Porto (IPO-Porto) were included, and the clinicopathological information was retrieved from the institutional database. Patients were stratified by body mass index (BMI). Statistical analysis included Pearson's chi-squared test with statistical significance set at p < 0.05. Multinomial, binary logistic regression and cox proportional-hazards model were also performed to calculate odd ratios and hazard ratios with 95% confidence intervals for adjusted and non-adjusted models. The results revealed no statistical difference in histological type, topographic localization, tumour stage and receptor status and in the number of surgical interventions. Overweight women have increased probability to be subjected to sentinel node biopsy. Obese and overweight women are more likely to be submitted to conservative surgery and contrariwise, less likely to undergo total mastectomy. Patients submitted to conservative surgery and not submitted to total mastectomy had a favourable OS although without statistical significance. No significant differences were observed in OS when stratified by BMI. Our results revealed significant variations regarding the surgical options in overweight and obese patients, but these were not translated in OS difference. More research is recommended to better address treatment options in overweight and obese BC patients.

Abstract
Molecular subtype (MS) is one of the most used classifications of breast cancer (BC). Four MSs are widely accepted according to receptor expression of estrogen, progesterone, and HER2. The impact of adipose tissue on BC MS metabolic impairment is still unclear. The present work aims to elucidate the metabolic alterations in breast cancer cell lines representing different MSs subjected to adipocyte associated factors. Preadipocytes isolated from human subcutaneous adipose tissue were differentiated into mature adipocytes. MS representative cell lines were exposed to mature adipocyte secretome. Extracellular medium was collected for metabolomics and RNA was extracted to evaluate enzymatic expression by RT-PCR. Adipocyte secretome exposure resulted in a decrease in the Warburg effect rate and an increase in cholesterol release. HER2+ cell lines (BT-474 and SK-BR-3) exhibited a similar metabolic pattern, in contrast to luminal A (MCF-7) and triple negative (TN) (MDA-MB-231), both presenting identical metabolisms. Anaplerosis was found in luminal A and TN representative cells, whereas cataplerotic reactions were likely to occur in HER2+ cell lines. Our results indicate that adipocyte secretome affects the central metabolism distinctly in each BC MS representative cell line.

Abstract
Inflammation may play a significant role in Keratoconus (KC), but the relationship between inflammatory markers and choroidal thickness (CT) is unknown. The purpose of this study was to evaluate serum inflammatory markers and correlate them with the choroidal profile of KC patients and control subjects. Forty patients with KC and 26 age-matched control subjects were enrolled in a cross-sectional case-control study. Choroidal profile was studied with a Spectralis Heidelberg apparatus and venous blood samples were collected. Neutrophil/lymphocyte ratio (NLR), monocyte/HDL ratio (MHR), platelet/lymphocyte ratio (PLR) and systemic immune inflammation index (SII) were calculated. Serum inflammatory biomarkers IL-1, IL-6 and TNF-alfa were also analyzed. KC group presented thicker choroids in each evaluated point when compared to the control group (subfoveal CT 417.38 ± 79.79 vs 299.61 ± 76.13, p < 0.001 for all measured locations). Mean values of NLR, PLR and SII were significantly higher in patients with KC (NLR p = 0.001; PLR p = 0.042; SII p = 0.007). Although KC patients presented higher mean levels of MHR, IL-1, IL-6 and TNF-α than control group, no significant differences were achieved. Positive correlations were found between subfoveal CT and NLR and SII (0.408, p = 0.001 and 0.288, p = 0.019 respectively). The results presented are in favor of a relationship between the increased CT and inflammatory mechanisms in KC patients. The elevated serum inflammatory indices NLR, SII and PLR provide additional evidence of a role for systemic inflammation in the pathophysiology of KC.

Abstract
BACKGROUND Faecalibacterium prausnitzii, one of the most important bacteria of the human gut microbiota, produces butyrate (a short-chain fatty acid). Short-chain fatty acids are known to influence thyroid physiology and thyroid cancer's response to treatment. We aimed to analyze the relative abundance of Faecalibacterium prausnitzii on the gut microbiota of differentiated thyroid cancer patients compared to controls and its variation after radioiodine therapy (RAIT). METHODS Fecal samples were collected from 37 patients diagnosed with differentiated thyroid cancer before and after radioiodine therapy and from 10 volunteers. The abundance of F. prausnitzii was determined using shotgun metagenomics. RESULTS Our study found that the relative abundance of F. prausnitzii is significantly reduced in thyroid cancer patients compared to volunteers. We also found that there was a mixed response to RAIT, with an increase in the relative and absolute abundances of this bacterium in most patients. CONCLUSIONS Our study confirms that thyroid cancer patients present a dysbiotic gut microbiota, with a reduction in F. prausnitzii's relative abundance. In our study, radioiodine did not negatively affect F. prausnitzii, quite the opposite, suggesting that this bacterium might play a role in resolving radiation aggression issues.

Abstract
BACKGROUND The gut microbiota is relatively stable; however, various factors can precipitate an imbalance that is known to be associated with various diseases. We aimed to conduct a systematic literature review of studies reporting the effects of ionizing radiation on the composition, richness, and diversity of the gut microbiota of animals. METHODS A systematic literature search was performed in PubMed, EMBASE, and Cochrane library databases. The standard methodologies expected by Cochrane were utilized. RESULTS We identified 3531 non-duplicated records and selected twenty-nine studies after considering the defined inclusion criteria. The studies were found to be heterogeneous, with significant differences in the chosen populations, methodologies, and outcomes. Overall, we found evidence of an association between ionizing radiation exposure and dysbiosis, with a reduction of microbiota diversity and richness and alterations in the taxonomic composition. Although differences in taxonomic composition varied across studies, Proteobacteria, Verrucomicrobia, Alistipes, and Akkermancia most consistently reported to be relatively more abundant after ionizing radiation exposure, whereas Bacteroidetes, Firmicutes, and Lactobacillus were relatively reduced. CONCLUSIONS This review highlights the effect of ionizing exposure on gut microbiota diversity, richness, and composition. It paves the way for further studies on human subjects regarding gastrointestinal side effects in patients submitted to treatments with ionizing radiation and the development of potential preventive, therapeutic approaches.

Abstract
OBJECTIVE The effect of diabetes on adhesive capsulitis (AC) and its impact on the outcomes of ultrasound (US)-guided hydrodistension of the glenohumeral joint are still unclear. We aimed to identify predictors of US-guided hydrodistension outcomes, while assessing the performance of the method in diabetic compared to non-diabetic patients. MATERIALS AND METHODS A total of 135 patients with AC who underwent US-guided hydrodistension were prospectively included. Demographics and factors linked to chronic inflammation and diabetes were recorded and patients were followed-up for 6 months. Functionality and pain were evaluated with the Disabilities of the Arm, Shoulder and Hand (DASH) and the Visual Analogue Scale (VAS) score. Statistical analysis was performed with Mann-Whitney U test, linear, and binary logistic regression. RESULTS Diabetes was identified in 25/135 patients (18.5%). Diabetic patients had worse DASH and VAS score at presentation (P < 0.0001) and presented with a higher grade of AC (P < 0.0001) and lower range of motion (P < 0.01) compared to non-diabetics. Higher DASH (P = 0.025) and VAS scores (P = 0.039) at presentation were linked to worse functionality at 6 months. Presence and duration of diabetes, and the number of hydrodistension repeats, correlated with worse VAS and DASH scores at 6 months. The number of procedure repeats was the only independent predictor of complete pain resolution at 6 months (OR 0.418, P = 003). CONCLUSION Diabetes is linked to more severe AC at presentation and worse outcomes in patients undergoing US-guided hydrodistension. In resistant cases, repeating the intervention is independently linked to worse outcomes for at least 6 months post-intervention.

Abstract
BACKGROUND In type 2 diabetes, insulin resistance is observed, and β-cells are incapable of responding to glycemia demands, leading to hyperglycemia. Although the nature of β-cells dysfunction in this disease is not fully understood, a link between the induction of pancreatic β-cell premature senescence and its metabolic implications has been proposed. This study aimed to understand the relationship between diabetes and pancreatic senescence, particularly at the beginning of the disease. METHODS C57Bl/6 J mice were fed two different diets, a normal diet and a high-fat diet, for 16 weeks. Pancreatic histomorphology analysis, insulin quantification, inflammation parameters, and senescence biomarkers for the experimental animals were assessed at weeks 12 and 16. RESULTS The results proved that diabetes onset occurred at week 16 in the High Fat Diet group, supported by glycaemia, weight and blood lipid levels. Increased β-cells size and number accompanied by increased insulin expression were observed. Also, an inflammatory status of the diabetic group was noted by increased levels of systemic IL-1β and increased pancreatic fibrosis. Finally, the expression of galactosidase-beta 1 (GLB1) was significantly increased in pancreatic β-cells. CONCLUSION The study findings indicate that senescence, as revealed by an increase in GLB1 expression, is a key factor in the initial stage of diabetes.

Abstract
Excessive UV radiation exposure is harmful to skin cells since sunburn is accompanied by oxidative burst, leading to a rapid increase in skin cancer. However, the insufficient UV photoprotection of approved sunscreens and the negative impact of their compositions on ecosystems and human health makes the utility of sunscreen a questionable recommendation. Therefore, discovering UV filters with significant antioxidant activity and improved topical performance and photostability is an urgent need. Recently, the use of nanosized natural molecules incorporated in sunscreens has been a scientific hot topic, as it has been suggested that they provide a synergistic effect with synthetic UV filters, improving overall SPF and antioxidant activity, higher retention on the epidermis, and less toxicity. The aim of this review was to verify the usefulness of sunscreens incorporating flavonoid-loaded nanoparticles. A literature review was performed, where original and review articles published in the last 6 years were analyzed. Formulations containing nanosized flavonoids with improved UVA photoprotection and safer toxicological profiles, associated or not with synthetic filters, are promising sunscreens and more clinical investigation must be performed to validate these findings.

Abstract
Prostate cancer (PCa) is the second most common malignancy in men, and the fifth leading cause of death worldwide. Mesenchymal stromal/stem cells (MSC) have been identified in PCa, although contradictory effects in malignant transformation and tumor progression have been described. Since umbilical cord (UC) MSC and cord blood serum (CBS) are rich in numerous growth and anti-inflammatory factors, UC-MSC secretome and CBS are able to modulate tumor cell proliferation and survival as well as immunity and angiogenesis. In the present study, we address this relationship and investigate the influence of UC-MSC secretome and CBS on two human PCa cell lines (PC3 and LNCaP) and a normal epithelial prostate cell line (HPEpiC). Our results disclosed that upon exposure to UC-MSC-conditioned medium or CBS, both PC3 and LNCaP cells exhibited reduced viability, proliferation, and motility while non-malignant epithelial prostate cells were unaffected. These findings were corroborated by expression analysis of AKT/PI3K signaling pathway, p53 and interleukin genes. UC-MSC and CBS factors decreased the expression of growth-stimulating AKT and PI3K effectors and simultaneously up-regulated the expression of tumor-suppressor p53. Moreover, a more anti-inflammatory expression profile was found in both malignant PCa cell lines. Altogether, these results shed light into possible mechanisms by which UC-MSC and CBS reduce PCa progression, further reinforcing their potential use as novel therapeutic agents in PCa.

Abstract
BACKGROUND Breast cancer (BC) and obesity are two closely associated pathologies with increasing incidence and mortality rates. Bilateral Breast Cancer (BBC) displays a low incidence rate within BC and obesity represents a major risk factor. OBJECTIVE The aim of this study is to analyzed BBC clinicopathological features distribution and determine the potential influence of obesity in BBC in these same features and overall survival. METHODS Clinicopathological information was obtained from 42 cases of women with BBC diagnosed in IPO-Porto. To evaluate the frequency distribution of the clinicopathological data, a chi-square goodness of fit test was performed for BBC cases. A chi-square test of independence was applied for BMI stratification. Cox regression was performed for overall survival. Statistical significance was set at p-value < 0.05. RESULTS Distribution of BBC clinicopathological features was found to be statistically significant in family history (p-value < 0.001), BBC type (p-value < 0.001), stage (p-value = 0.005), differentiation grade (p-value < 0.001), receptor expression (p-value < 0.001) and histological type (p-value = 0.031). In comparison to the statistical expected results, we observed an increased cases of absence of family history and less cases of metachronous BBC. Histological types between tumours of BBC were mostly concordant. All cases presented concordant receptor expression. Analysis stratified by BMI revealed that obese women were diagnosed later, although without statistical significance. All obese women presented poor differentiation grade (n = 6). Overweight patients display a tendency to a better overall survival with lower tumour stages and lower differentiation grades. CONCLUSIONS Our results reveal the same receptor expression between contralateral tumours. Also, most tumours share the same histological type. When stratified by BMI, we observed a tendency for overweight women to have improved overall survival.

Abstract
Cancer is a major health problem worldwide and the second leading cause of death following cardiovascular diseases. Breast cancer is the leading cause of mortality and morbidity among women and one of the most common malignant neoplasms prompt to metastatic disease. In the present review, the mechanisms of the major cell adhesion molecules involved in tumor invasion are discussed, focusing on the case of breast cancer. A non-systematic updated revision of the literature was performed in order to assemble information regarding the expression of the adhesion cell molecules associated with metastasis.

Abstract
Date seed is a by-product of Phoenix dactylifera L. fruit which is well recognized for its polyphenols content and numerous health-beneficial effects. Due to the increasing interest in natural phytochemicals with antioxidant activities, the present study aimed to extract polyphenols from both raw and roasted date seeds and investigate the anti-angiogenic effect of these two extracts (raw and roasted date seed polyphenols extracts (DSPE) at 25 and 50 µg/mL) using human microvascular endothelial cells (HMVEC). Our results showed that both raw and roasted DSPE suppressed some angiogenesis features in a dose-dependent manner including cell proliferation, migration, and capillary-like structure formation, of which raw DSPE was more potent inhibitor than roasted DSPE. Reduction in reactive oxygen species, as well as enhancement of superoxide dismutase activity occurred using both raw and roasted date seed polyphenols extracts. However, no changes were observed in advanced oxidation protein products versus control. Taken together, our data indicated that raw and roasted DSPE possess antioxidant activity, which suggested their potential use as a source of polyphenols with anti-angiogenic properties. Nevertheless, further studies are required to explore the underlying mechanisms responsible for their anti-angiogenic activities.

Abstract
OBJECTIVES Metabolically healthy obese (MHO) children is a described subgroup of obese children who do not exhibit traditional cardiometabolic risk factors. The aim of this study was to determine the prevalence and characterize patients with this phenotype. METHODS Cross-sectional study, performed in a paediatric obesity clinic (tertiary university hospital) in 2019. Children were classified with "MHO" or "metabolically unhealthy obesity" according to the criteria proposed by Damanhoury based on HDL, triglycerides, systolic and diastolic blood pressure (DBP) and fasting glucose values. RESULTS 241 participants were included, with ages between two and 17 years. The prevalence of the MHO phenotype was 61.8%. The body mass index (Z-score) in children aged five years or older was significantly lower in those with MHO (p=0.040). In the MHO group, mean total cholesterol levels were higher (p<0.001), due to the high value of HDL (p<0.001); triglyceride levels (p<0.001), systolic blood pressure (SBP) (p=0.036), DBP (p=0.029) and the homeostasis model assessment - insulin resistance (HOMA-IR) index (p=0.001) were significantly lower. HDL (OR=1.421; 95% CI 1.279-1.579; p<0.001) and SBP (OR=0.943; 95% CI 0.903-0.985; p=0.008) were the only independent predictors for the development of MHO. CONCLUSIONS Almost two-thirds of the participants had an MHO phenotype. The high and low values of HDL and SBP, respectively, were the only variables that proved to be predictors of MHO.

Abstract
Aging is a natural physiological process, but one that poses major challenges in an increasingly aging society prone to greater health risks such as diabetes, cardiovascular disease, cancer, frailty, increased susceptibility to infection, and reduced response to vaccine regimens. The loss of capacity for cell regeneration and the surrounding tissue microenvironment itself is conditioned by genetic, metabolic, and even environmental factors, such as nutrition. The senescence of the immune system (immunosenescence) represents a challenge, especially when associated with the presence of age-related chronic inflammation (inflammaging) and affecting the metabolic programming of immune cells (immunometabolism). These aspects are linked to poorer health outcomes and therefore present an opportunity for host-directed interventions aimed at both eliminating senescent cells and curbing the underlying inflammation. Senotherapeutics are a class of drugs and natural products that delay, prevent, or reverse the senescence process – senolytics; or inhibit senescence-associated secretory phenotype – senomorphics. Natural senotherapeutics from food sources – nutritional senotherapeutics – may constitute an interesting way to achieve better age-associated outcomes through personalized nutrition. In this sense, the authors present herein a framework of nutritional senotherapeutics as an intervention targeting immunosenescence and immunometabolism, identifying research gaps in this area, and gathering information on concluded and ongoing clinical trials on this subject. Also, we present future directions and ideation for future clinical possibilities in this field.

Abstract
Prostate cancer (PCa) remains the second most common type of cancer in men worldwide in 2020. Despite its low death rate, the need for new therapies or prevention strategies is critical. The prostate carcinogenesis process is complex and multifactorial. PCa is caused by a variety of mutations and carcinogenic events that constitutes the disease’s multifactorial focus, capable of not only remodeling cellular activity, but also modeling metabolic pathways to allow adaptation to the nutritional requirements of the tumor, creating a propitious microenvironment. Some risk factors have been linked to the development of PCa, including Metabolic Syndrome (MetS) and Type 2 Diabetes Mellitus (T2DM). MetS is intrinsically related to PCa carcinogenic development, increasing its aggressiveness. On the other hand, T2DM has the opposite impact, although in other carcinomas its effect is similar to the MetS. Although these two metabolic disorders may share some developmental processes, such as obesity, insulin resistance, and dyslipidemia, their influence on PCa prognosis appears to have an inverse effect, which makes this a paradox. Understanding the phenomena behind this paradoxical behavior may lead to new concepts into the comprehension of the diseases, as well as to evaluate new therapeutical targets. Thus, this review aimed to evaluate the impact of metabolic disorders in PCa’s aggressiveness state and metabolism.

Abstract
OBJECTIVES This article aims to analyse the safety of feline blood donation by describing the frequency and nature of any adverse reactions and their causes, as well as propose measures to decrease the incidence of adverse reactions. METHODS In this prospective study, any blood donor adverse reactions detected by the clinical staff during and immediately after donation were recorded. The owners of the cats were also surveyed by a veterinary practitioner or veterinary nurse 5 days after donation, using a predefined questionnaire to assess for any clinical or behavioural changes. Data were collected between January 2019 and March 2020 from blood donors enrolled in an animal blood bank programme. RESULTS Of 3690 blood donations from 1792 feline donors assessed, post-donation reactions were reported in 1.14% (n = 42): 0.22% (n = 8) were acute reactions, which included weakness, pallor, tachypnoea and open-mouth breathing; and 0.92% (n = 34) were delayed post-donation reactions, with 0.16% involving cutaneous (haematomas and skin rashes, n = 6), 0.68% involving behavioural (n = 25) and 0.08% involving digestive (emesis and inappetence, n = 3) signs. CONCLUSIONS AND RELEVANCE The low incidence of post-donation reactions in this study is encouraging, suggesting that a well-established protocol and competent staff can help to ensure a high level of safety in a feline donor programme and, in turn, increase the confidence of cat owners.

Abstract
Bariatric surgery (BS) is the most effective therapy for severe obesity, which improves several comorbidities (such as diabetes, hypertension, dyslipidemia, among others) and results in marked weight loss. Despite these consensual beneficial effects, sleeve gastrectomy and Roux-en-Y gastric bypass (the two main bariatric techniques) have also been associated with changes in bone metabolism and progressive bone loss. The objective of this literature review is to examine the impact of bariatric surgery on bone and its main metabolic links, and to analyze the latest findings regarding the risk of fracture among patients submitted to bariatric surgery.

Introduction
The ratio of echocardiography-derived tricuspid annular plane systolic excursion (TAPSE) and pulmonary arterial systolic pressure (PASP) - TAPSE/PASP ratio - is a noninvasive measure of RV-arterial coupling. TAPSE/PASP ratio is a potent independent predictor of prognosis in heart failure and pulmonary arterial hypertension, with a prognostic cutoff value of 0.36 mm/mmHg.
Objective
To assess the prognostic impact of TAPSE/PASP ratio in a population of advanced HF patients.
Methods
Prospective evaluation of adult patients with advanced HFrEF referred to our Institution for evaluation with HF team and possible indication for urgent heart transplantation (HT) or MCS. Patients were followed up for 2 years for the primary endpoint of cardiac death and HT. Echocardiographically determined TAPSE/PASP ratio was used to assess RV-arterial coupling and a survival analysis was performed to evaluate the prognostic impact of the suggested cutoff of 0.36 mm/mmHg.
Results
A total of 450 Heart Failure with Reduced Ejection Fraction (HFrEF) patients with a mean age of 56 ± 12 years, of which 80% are male, and with a mean LVEF of 29 ± 4%, mean TAPSE of 19 ± 3 mm and PASP of 38 ± 11mmHg. The mean TAPSE/PASP was 0.80 ± 0.28. Fifty-four patients (12%) met the primary endpoint. Patients with RV-arterial uncoupling (TAPSE/PASP < 0.36 mm/mmHg) were more likely to have a non-ischaemic etiology for HF (66.7% vs 40%, p = 0.047), had a lower prevalence of diabetes (53.3% vs 77.9%, p = 0.041), a higher prevalence of moderate-to-severe mitral regurgitation (33.3% vs 13.0%, p = 0.035), a lower LVEF (26.2 ± 6.1 vs 29.9 ± 5.9, p = 0.038), a higher prevalence of RV dysfunction (73.3% vs 26.7%, p < 0.001) and worse cardiopulmonary fitness (pVO2: 12.7 ± 5.1 vs 15.8 ± 6.0 ml/kg/min, p = 0.047; VE/VCO2 slope: 49.5 ± 17.2 vs 37.6 ± 9.7, p < 0.001; cardiorespiratory optimal point: 36.9 ± 11.3 vs 29.0 ± 6.4, p < 0.001). More patients in the group of TAPSE/PASP < 0.36 mm/mmHg met the primary endpoint (33.3% vs 9.6%, p = 0.034) and more patients underwent urgent HT (13.3% vs 1.4%, p = 0.44). RV-arterial coupling was associated with a lower survival free of events during follow-up (log-rank p = 0.010).
Conclusion
RV-arterial coupling predicts a worse prognosis in advanced HF patients, with those below a cutoff of 0.36 mm/mmHg having lower survival. This variable may improve risk stratification in this setting. Abstract Figure.

Introduction
In patients with heart failure with reduced ejection fraction (HFrEF), the presence of coexistent right ventricular (RV) systolic dysfunction is associated with a worse functional capacity and outcome. However, the measurement of RV function is often overshadowed by its left counterpart.
Purpose
To assess the prognostic impact of RV dysfunction in a population of advanced HF patients.
Methods
Prospective evaluation of adult patients with advanced HFrEF referred to our Institution for evaluation with HF team for possible indication for urgent heart transplantation (HT) or MCS. Patients were followed up for 1 year for the primary endpoint of cardiac death and HT. RV systolic dysfunction was defined by a tricuspid annular plane systolic excursion (TAPSE) < 17 mm and/ or fractional area change (FAC) < 35%. A survival analysis was performed to evaluate the prognostic impact of RV dysfunction and survival curves were compared using the log-rank test.
Results
A total of 450 HFrEF patients (mean age of 56 ± 12 years, 80% male, mean LVEF of 29 ± 4%, mean TAPSE of 19 ± 3 mm and RV FAC of 37 ± 6%), of which 30.4% had RV dysfunction. Thirty patients (6.7%) met the primary endpoint. Patients with RV dysfunction had a higher NT-proBNP value (3278.9 ± 296.7 pg/mL, p = 0.005) and a lower LVEF (26.7 ± 6.4 vs 31.4 ± 5.1, p < 0.001), as well as a worse cardiopulmonary fitness (CPET duration: 7.2 ± 3.8 vs 8.6 ± 4.1, p = 0.019; pVO2: 13.6 ± 4.9 vs 16.2 ± 6.1 ml/kg/min, p = 0.006; VE/VCO2 slope: 41.8 ± 11.9 vs 37.0 ± 10.6, p = 0.015; cardiorespiratory optimal point: 33.0 ± 8.9 vs 28.4 ± 6.2, p < 0.001). RV dysfunction was associated with a lower survival free of events during the first follow-up year (log-rank p = 0.046).
Conclusion
RV is associated with a poor survival in advanced HF patients and it may improve risk stratification in this population. Abstract Figure.

Introduction
Moderate-to-severe functional mitral regurgitation (fMR) is present in about one-third of patients with heart failure (HF) with reduced left ventricular (LV) ejection fraction (HFrEF) and contributes to progression of the symptoms of HF and is and independent predictor of worse clinical outcomes.
Objective
To characterize the population of advanced HF patients with severe fMR and assess its prognostic impact.
Methods
Prospective evaluation of adult patients with advanced HFrEF were referred to our Institution for evaluation with HF team and possible indication for urgent heart transplantation (HT) or MCS. Patients were followed up for 1 year for the primary endpoint of cardiac death and HT. Severe fMR was defined by an EROA ≥ 20 mm2 and/or a regurgitant volume (RVol) ≥ 30 mL either taken from TTE or TOE. A survival analysis was performed to evaluate the prognostic impact of fMR and survival curves were compared using the log-rank test.
Results
A total of 450 HFrEF patients (mean age of 56 ± 12 years, 80% male, mean LVEF of 29 ± 4%) of which 14.4% had severe fMR, with a mean EROA of 29.2 ± 3.1 mm2 and a mean RVol of 43.6 ± 4.7 mL. Thirty patients (6.7%) met the primary endpoint. Patients with severe fMR were more likely to be female (69.2% vs 81.5%, p = 0.026) and to have atrial fibrillation (27.0% vs 14.1%, p = 0.028), had a higher NT-proBNP value (3625.8 ± 496.9 vs 1940 ± 212.4 pg/mL, p = 0.001), a lower LVEF (25.9 ± 6.8 vs 29.0 ± 6.7, p = 0.001), more dilated LV (LV end-diastolic diameter: 72.8 ± 13.3 vs 66.9 ± 9.0 P = 0.036), a lower HFSS value (8.1 ± 1.0 vs 8.6 ± 1.0). There was no difference regarding HF etiology, NYHA class or cardiopulmonary fitness (pVO2: 16.6 ± 5.6 vs 16.5 ± 6.3 ml/kg/min, p = 0.19; VE/VCO2 slope: 35.4 ± 9.9 vs 34.0 ± 9.7, p = 0.328). EROA was an independent predictor of the primary outcome (OR 1.23, 95% CI 1.08-1.54, p = 0.039) and patients with severe fMR had a lower survival free of events during the first follow-up year (log-rank p = 0.012).
Conclusion
Severe fMR was associated with worse clinical outcomes in advanced HF population. Abstract Figure.

Abstract
Type 2 Diabetes (T2D) is currently one of the fastest growing health challenging, a non-communicable disease result of the XXI century lifestyle. Given its growing incidence and prevalence, it became increasingly imperative to develop new technologies and implement new biomarkers for early diagnosis in order to promote lifestyle changes and thus cause a setback of the disease. Promising biomarkers have been identified as predictive of T2D development; however, none of them have yet been implemented in clinical practice routine. Moreover, many prediabetic biomarkers can also represent potential therapeutical targets in disease management. Previous studies have identified the most popular biomarkers, which are being thoroughly investigated. However, there are some biomarkers with promising preliminary results with limited associated studies; hence there is still much to be understood about its mechanisms and associations in T2D pathophysiology. This work identifies and discusses the promising results of Galectin-3, Ophthalmate and Fetuin-A.

Abstract
Obesity is a risk factor for malignant melanoma. The lungs are main target organs for metastization and their immune response is a key modulator of this mechanism. The concept that the metastatic potential of some types of cancer is reduced or inhibited by obesity, known as the obesity paradox, drives major concerns on the prognosis of metastasized patients. The aim of this study was to investigate how high-fat diet (HFD)-induced obesity affects melanoma metastization. C57Bl6/J mice were fed with HFD or standard diet for 180 days and inoculated intravenously with B16F10 melanoma cells. Upon 21 days of inoculation, lung tissue of overweight and lean mice was assessed for histology and immunohistochemistry assays. Adipokine antibody arrays were performed in mice serum. In vitro RAW 264.7 macrophage cultures were established and incubated with FGF-21 and/or lipopolysaccharide (LPS). Conditioned media was added to B16F10 cells for viability quantification. HFD-fed mice presented a reduced number of metastases with lower proliferative rates. The high content of inflammatory foci observed in noninoculated obese mice was significantly decreased upon B16F10 inoculation, concurrent with a slight fibrosis reduction. Plasma levels of fibroblast growth factor-21 (FGF-21), an endocrine regulator, were elevated in noninoculated HFD mice and the expression of FGF receptor 1 (FGFR-1) was significantly upregulated after inoculation. FGF-21 reduced melanoma viability in LPS-stimulated macrophages. Altogether, these findings suggest that higher amounts of FGF-21 are able to counterbalance the proinflammatory effects associated with obesity, protecting the lungs from melanoma metastization.

Abstract
During the pathophysiological course of type 2 diabetes (T2D), several metabolic imbalances occur. There is increasing evidence that metabolic dysfunction far precedes clinical manifestations. Thus, knowing and understanding metabolic imbalances is crucial to unraveling new strategies and molecules (biomarkers) for the early-stage prediction of the disease's non-clinical phase. Lifestyle interventions must be made with considerable involvement of clinicians, and it should be considered that not all patients will respond in the same manner. Individuals with a high risk of diabetic progression will present compensatory metabolic mechanisms, translated into metabolic biomarkers that will therefore show potential predictive value to differentiate between progressors/non-progressors in T2D. Specific novel biomarkers are being proposed to entrap prediabetes and target progressors to achieve better outcomes. This study provides a review of the latest relevant biomarkers in prediabetes. A search for articles published between 2011 and 2021 was conducted; duplicates were removed, and inclusion criteria were applied. From the 29 studies considered, a survey of the most cited (relevant) biomarkers was conducted and further discussed in the two main identified fields: metabolomics, and miRNA studies.

Abstract
Cutaneous melanoma is the deadliest type of skin cancer and current treatment is still inadequate, with low patient survival rates. The polyphenol xanthohumol has been shown to inhibit tumourigenesis and metastasization, however its physicochemical properties restrict its application. In this work, we developed PLGA nanoparticles encapsulating xanthohumol and tested its antiproliferative, antitumour, and migration effect on B16F10, malignant cutaneous melanoma, and RAW 264.7, macrophagic, mouse cell lines. PLGA nanoparticles had a size of 312 ± 41 nm and a PdI of 0.259, while achieving a xanthohumol loading of about 90%. The viability study showed similar cytoxicity between the xanthohumol and xanthohumol-loaded PLGA nanoparticles at 48 h with the IC50 established at 10 µM. Similar antimigration effects were observed for free and the encapsulated xanthohumol. It was also observed that the M1 antitumor phenotype was stimulated on macrophages. The ultimate anti-melanoma effect emerges from an association between the viability, migration and macrophagic phenotype modulation. These results display the remarkable antitumour effect of the xanthohumol-loaded PLGA nanoparticles and are the first advance towards the application of a nanoformulation to deliver xanthohumol to reduce adverse effects by currently employed chemotherapeutics.

Abstract
Abstract
Introduction
There is evidence suggesting that a peak oxygen uptake (pVO2) cut-off of 10ml/kg/min provides a more precise risk stratification in Cardiac Resynchronization Therapy (CRT) patients. Our aim was to compare the prognostic power of several cardiopulmonary exercise testing (CPET) parameters in patients with CRT and assess the discriminative ability of the guideline-recommended pVO2 cut-off values.
Methods
Prospective evaluation of consecutive heart failure (HF) patients with left ventricular ejection fraction ≤40%. The primary endpoint was a composite of cardiac death and urgent heart transplantation (HT) in the first 24 follow-up months and was analyzed by several CPET parameters for the highest area under thecurve (AUC) in the CRT group. A survival analysis was performed to evaluate the risk stratification provided by several different cut-offs.
Results
A total of 450 HF patients, of which 114 had a CRT device. These patients had a higher baseline risk profile, but there was no difference regarding the primary outcome (13.2% vs 11.6%, p=0.660). End-tidal carbon dioxide pressure at the anaerobic threshold (PETCO2AT) had the highest AUC value, which was significantly higher than that of pVO2 in the CRT group (0.951 vs 0.778, p=0.046). The currently recommended pVO2 cut-off provided accurate risk stratification in this setting (p<0.001),and the suggested cut-off value of 10 ml/min/kg did not improve risk discrimination in device patients (p=0.772).
Conclusion
PETCO2AT outperforms pVO2's prognostic power for adverse events in CRT patients. The current guideline-recommended pVO2 cut-off can precisely risk-stratify this population.

Abstract
BACKGROUND The human gut microbiota is defined as the microorganisms that collectively inhabit the intestinal tract. Its composition is relatively stable; however, an imbalance can be precipitated by various factors and is known to be associated with various diseases. Humans are daily exposed to ionizing radiation from ambient and medical procedures, and gastrointestinal side effects are not rare. METHODS A systematic search of PubMed, EMBASE, and Cochrane Library databases was conducted. Primary outcomes were changes in composition, richness, and diversity of the gut microbiota after ionizing radiation exposure. Standard methodological procedures expected by Cochrane were used. RESULTS A total of 2929 nonduplicated records were identified, and based on the inclusion criteria, 11 studies were considered. Studies were heterogeneous, with differences in population and outcomes. Overall, we found evidence for an association between ionizing radiation exposure and dysbiosis: reduction in microbiota diversity and richness, increase in pathogenic bacteria abundance (Proteobacteria and Fusobacteria), and decrease in beneficial bacteria (Faecalibacterium and Bifidobacterium). CONCLUSIONS This review highlights the importance of considering the influence of ionizing radiation exposure on gut microbiota, especially when considering the side effects of abdominal and pelvic radiotherapy. Better knowledge of these effects, with larger population studies, is needed.

Abstract
A 79-year-old man was admitted to our ward with symptomatic heart failure 2 months after aortic valve replacement due to severe aortic stenosis. On the third day following admission, he became febrile (>38°C) while manifesting an increase in inflammatory markers. Endocarditis was suspected despite negative blood cultures. Echocardiogram (transthoracic and transesophageal) did not describe any vegetations. No hypermetabolic lesions were described on the Positron emission tomography scan. Empirical antibiotics were started but the fever persisted. Serologies revealed a Coxiella burnetii IgG phase II titre of 1:800, high erythrocyte sedimentation rate. Positive antinuclear antibodies, antibeta2 IgM and anticardiolipin supported a diagnosis of acute Q fever endocarditis. Doxycycline and hydroxychloroquine were started with total resolution of symptoms. This case illustrates the difficulty of diagnosing Q fever endocarditis during its acute phase, not only because vegetations can be minimal or absent, a challenge that is further compounded by a complex presentation of immunological markers.

Abstract
Objective The aim is to examine the effect of metformin in human microvascular endothelial cells exposed to high
glucose (HG) concentration and compare them with the effects of other 5' adenosine monophosphate-activated protein
kinase (AMPK) modulators under the same condition.
Materials and Methods In this experimental study, human microvascular endothelial cells (HMECs) were treated
with 15 mM metformin, 1 mM 5-aminoimidazol-4-carboxamideribonucleotide (AICAR) and 10 mM compound C in the
presence of 20 mM glucose (hyperglycemic condition). Migration, invasion and proliferation were evaluated as well as
the capillary-like structures formation. Moreover, the expression of angiogenic genes was assessed.
Results Metformin significantly inhibited vessel formation and migration, although it did not change HMECs proliferation
and invasion. In addition, metformin significantly reduced collagen formation as evidenced by histological staining.
Concomitantly, expression of several genes implicated in angiogenesis and fibrosis, namely TGFß2, VEGFR2, ALK1,
JAG1, TIMP2, SMAD5, SMAD6 and SMAD7, was slightly upregulated. Immunostaining for proteins involved in ALK5
receptor signaling, the alternative TGFß signaling pathway, revealed significant differences in SMAD2/3 expression.
Conclusion Our data showed that metformin prevents vessel assembly in HMECs, probably through an AMPK-
independent mechanism. Understanding the molecular mechanisms by which this pharmacological agent affects
endothelial dysfunction is of paramount importance and paves the way to its particular use in preventing development
of diabetic retinopathy and nephropathy, two processes where angiogenesis is exacerbated.

Abstract
ABSTRACT The aim of this study was to investigate the occurrence of diseases in free-ranging wild canids that were roadkill on highways in the State of Espírito Santo, Brazil. PCR tests were performed for the detection of Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. in the spleen. Morphological evaluation and identification of parasites was performed in the liver and lung. Twenty specimens of C. thous were necropsied at the Animal Pathology Sector of the Veterinary Hospital of the Universidade Federal do Espírito Santo. Tissue samples were processed for histopathological examination and polymerase chain reaction (PCR) analysis. There was no PCR amplification of genomic DNA sequences of Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. using DNA extracted from the spleen as template. Histologically, lesions associated with parasitism by Platynosomum sp. and Angiostrongylus sp. were observed in the liver and lung, respectively. This is the first report of Platynosomum sp. and Angiostrongylus sp. parasitism in C. thous in the state of Espírito Santo, Brazil. Therefore, this study demonstrated parasitism of crab-eating foxes by Platynosomum sp. and Angiostrongylus sp. Importantly, no evidence of infection with Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. was obtained by PCR analysis.

Abstract
The Euterpe oleracea fruit (açaí) is a promising source of polyphenols with health-promoting properties. To our knowledge, few studies have focused on the influence of açaí phytochemicals on angiogenesis, with a significant impact on cancer. This study aimed at investigating the phytochemical profile of a purple açaí hydroethanolic extract (AHE) obtained from a commercial dietary powder supplement by high-performance liquid chromatography coupled to diode array detection and electrospray ionization mass spectrometry, and evaluate its in vitro effects on distinct angiogenic steps during vessel growth and on oxidative markers in human microvascular endothelial cells (HMEC-1). The phenolic profile of AHE revealed the presence of significant levels of anthocyanins, mainly cyanidin-3-O-rutinoside, and other flavonoids with promising health effects. The in vitro studies demonstrated that AHE exerts antiangiogenic activity with no cytotoxic effect. The AHE was able to decrease HMEC-1 migration and invasion potential, as well as to inhibit the formation of capillary-like structures. Additionally, AHE increased antioxidant defenses by upregulating superoxide dismutase and catalase enzymatic activities, accompanied by a reduction in the production of reactive oxygen species. These data bring new insights into the potential application of angiogenic inhibitors present in AHE on the development of novel therapeutic approaches for angiogenesis-dependent diseases.

Abstract
In situ cross-linked hydrogels have the advantage of effectively fulfilling the wound in its shape and depth. Amongst the new generation of natural-based biopolymers being proposed for wound care and skin regeneration, silk sericin is particularly interesting due to its exceptional properties such as biocompatibility, biodegradability, and antioxidant behavior, among others. In this study, a new enzyme-mediated cross-linked hydrogel composed of silk sericin is proposed for the first time. The developed hydrogel cross-linking strategy was performed via horseradish peroxidase, under physiological conditions, and presented gelling kinetics under 3 min, as demonstrated by its rheological behavior. The hydrogels presented a high degree of transparency, mainly due to their amorphous conformation. Degradation studies revealed that the hydrogels were stable in phosphate buffer solution (PBS) (pH 7.4) for 17 days, while in the presence of protease XIV (3.5 U/mg) and under acute and chronic physiological pH values, the stability decreased to 7 and 4 days, respectively. During protease degradation, the present sericin hydrogels demonstrated antioxidant activity. In vitro studies using an L929 fibroblast cell line demonstrated that these hydrogels were noncytotoxic, promoting cell adhesion and massive cell colonization after 7 days of culture, demonstrating that cells maintained their viability and proliferation. In addition, the application of sericin-based hydrogel in an in vivo diabetic wound model validated the feasibility of the in situ methodology and demonstrated a local anti-inflammatory effect, promoting the healing process. This study presents a simple, fast, and practical in situ approach to produce a sericin-based hydrogel able to be applied in low exudative chronic wounds. Moreover, the study herein reported fosters the valorization of a textile industrial by-product by its integration in the biomedical field.

Abstract
Abstract
Background
Peak oxygen consumption (pVO2) is a key parameter in assessing the prognosis of heart failure with reduced ejection fraction (HFrEF) patients (pts). However, it is a less reliable parameter when the cardiopulmonary exercise test (CPET) is not maximal. It is crucial to identify the submaximal exercise variables with the best prognostic power (PP), in order to improve the management of pts that cannot attain a maximal CPET.
Purpose
The aim of this study was to evaluate and compare the PP of several exercise parameters in submaximal CPET for risk stratification in pts with HFrEF.
Methods
Prospective evaluation of adult pts with HFrEF submitted to CPET in a tertiary center. A submaximal CPET was defined by a respiratory exchange ratio (RER) ≤1.10. Pts were followed up for at least 1 year for the primary endpoint of cardiac death and urgent heart transplantation/ ventricular assist device implantation. Several CPET parameters were analyzed as potential predictors of the combined endpoint and their PP (area under the curve - AUC) was compared to that of pVO2, using the Hanley and McNeil test.
Results
CPET was performed in 487 HF pts, of which 317 (66%) performed a submaximal CPET. Pts averaged 57±12 years of age, 77% were male, 45.7% had ischemic cardiomyopathy, with a mean LVEF of 30.4±7.6%, a mean heart failure survival score of 8.6±1.1. The mean pVO2 was 17.1±5.5 ml/kg/min and the mean RER 1.01±0.08. During a mean follow-up (FU) time of 11±1 months, 18 pts (6%) met the primary endpoint. Cardiorespiratory optimal point (OP - VE/VO2) had the highest AUC value (0.915, p=0.001), followed by the partial pressure of end-tidal CO2 at the anaerobic threshold - PETCO2L (0.814, p<0.001). pVO2 presented an AUC of 0.730 (p=0.001). OP≥31 and PETCO2L ≤37mmHg had a sensitivity of 100 and 76.9% and a specificity of 71.1 and 67%, respectively, for the primary outcome. OP presented a significantly higher PP than pVO2 (p=0.048), whether PETCO2L didn't achieve any statistical significance (p=0.164). Pts with anOP≥31 presented a significantly lower survival free of HT during FU (log rank p=0.002).
Conclusion
OP had the highest PP for HF events of all parameters analyzed for a submaximal CPET. This parameter can help stratify the HF pts physiologically unable to reach a peak level of exercise.

Abstract
Interactions between cell types, growth factors, and extracellular matrix components involved in angiogenesis are crucial for new vessel formation leading to tissue regeneration. This study investigated whether cocultures of fibroblasts and endothelial cells (ECs; from macro- or microvasculature) play a role in the formation of microvessel-like structures by ECs, as well as modulate fibroblast differentiation and growth factors production (vascular endothelial cell growth factor, basic fibroblast growth factor, active transforming growth factor-β1, and interleukin-8), which are important for vessel sprouting and maturation. Data obtained revealed that in vitro coculture systems of fibroblasts and human ECs stimulate collagen synthesis and growth factors production by fibroblasts that ultimately affect the formation and distribution of microvessel-like structures in cell cultures. In this study, areas with activated fibroblasts and high alkaline phosphatase (ALP) activity were also observed in cocultures. Molecular docking assays revealed that ALP has two binding positions for collagen, suggesting its impact in collagen proteins' aggregation, cell migration, and microvessel assembly. These findings indicate that bioinformatics and coculture systems are complementary tools for investigating the participation of proteins, like collagen and ALP in angiogenesis.

Abstract
Background:
Quinoxaline-1,4-dioxide (QNX) derivatives are synthetic heterocyclic compounds with
multiple biological and pharmacological effects.
Objective:
In this study, we investigated the oxidative status of quinoxaline-1,4-dioxides derivatives in modulating
melanoma and glioma cell lines, based on previous results from the research group and their capability to
promote cell damage by the production of Reactive Oxygen Species (ROS).
Methods:
Using in vitro cell cultures, the influence of 2-amino-3-cyanoquinoxaline-1,4-dioxide (2A3CQNX), 3-
methyl-2-quinoxalinecarboxamide-1,4-dioxide (3M2QNXC) and 2-hydroxyphenazine-1,4-dioxide (2HF) was
evaluated in metabolic activity, catalase activity, glutathione and 3-nitrotyrosine (3-NT) quantitation by HPLC
in malignant melanocytes (B16-F10, MeWo) and brain tumor cells (GL-261 and BC3H1) submitted to radiotherapy
treatments (total dose of 6 Gy).
Results:
2HF increased the levels of 3-NT in non-irradiated MeWo and glioma cell lines and decreased cell
viability in these cell lines with and without irradiation.
Conclusions:
Quinoxaline-1,4-dioxides derivatives modulate the oxidative status in malignant melanocytes and
brain tumor cell lines and exhibited a potential radiosensitizer in vitro action on the tested radioresistant cell
lines.

Abstract
Recently, multiple studies regarding the human microbiota and its role on the development of disease have emerged. Current research suggests that the nasal cavity is a major reservoir for opportunistic pathogens, which can then spread to other sections of the respiratory tract and be involved in the development of conditions such as allergic rhinitis, chronic rhinosinusitis, asthma, pneumonia, and otitis media. However, our knowledge of how nasal microbiota changes originate nasopharyngeal and respiratory conditions is still incipient. Herein, we describe how the nasal microbiome in healthy individuals varies with age and explore the effect of nasal microbiota changes in a range of infectious and immunological conditions. We also describe the potential health benefits of human microbiota modulation through probiotic use, both in disease prevention and as adjuvant therapy. Current research suggests that patients with different chronic rhinosinusitis phenotypes possess distinct nasal microbiota profiles, which influence immune response and may be used in the future as biomarkers of disease progression. Probiotic intervention may also have a promising role in the prevention and adjunctive treatment of acute respiratory tract infections and allergic rhinitis, respectively. However, further studies are needed to define the role of probiotics in the chronic rhinosinusitis.

Abstract
Abstract
Introduction
Sacubitril/Valsartan (LCZ696) significantly reduced sudden cardiac death in the PARADIGM-HF trial. However, there is little published data regarding the possible explanations for the antiarrhythmic effects found with LCZ696 therapy.
Previous trials have shown that mechanical dispersion by strain echocardiography can predict arrhythmic events in Heart Failure (HF) patients.
The aim of this study was to compare electrocardiographic (ECG) parameters and mechanical dispersion index with left ventricular (LV) global longitudinal strain (GLS) analysis before and after LCZ696 therapy.
Methods
Prospective evaluation of chronic HF patients with LV ejection fraction ≤ 40% despite optimized standard of care therapy, in which LCZ696 therapy was started and no additional HF treatment was expected to change.
ECG and transthoracic echocardiographic data were gathered in the week before starting LCZ696 therapy and 6 months after therapy. A semiautomated analysis of LV GLS was made and mechanical dispersion index was defined as the standard deviation from the 16 time intervals corresponding to each LV segment.
Results
Of the 42 patients, 35 (83.3%) completed the 6 months of follow-up, since 2 (4.8%) patients died and 5 (11.9%) discontinued treatment for adverse events. Mean age was 58.6 ± 11.1 years.
QTc interval (451.9 vs 426.0msec, p < 0.001) and QRS interval (125.1 vs 120.8msec, p = 0.033) were reduced after 6 months of LCZ696 therapy. Mechanical dispersion index (88.4 vs 78.1msec, p = 0.036) was also significantly reduced after therapy.
Conclusion
LCZ696 therapy is associated with antiarrhythmic effects with a reduction in QTc and QRS intervals in ECG and a reduction in mechanical dispersion index as assessed by LV GLS.

Abstract
Abstract
Introduction
Myocardial work (MW) is a new transthoracic echocardiographic (TTE) parameter that enhances the information provided through left ventricular (LV) global longitudinal strain (GLS), allowing to investigate LV performance even in cases of changes in afterload.
None is known about the effects of Sacubitril-Valsartan (LCZ696) therapy in MW parameters.
Purpose
Compare the changes in MW parameters between ischemic and non-ischemic segments after LCZ696 therapy.
Methods
The study was a prospective evaluation of chronic Heart Failure (HF) patients with optimized standard of care therapy and LV ejection fraction ≤40%, in which LCZ696 therapy was started and no other HF treatment was expected to change.
A TTE study was performed before and 6 months after LCZ696 therapy, using the GE Vivid E95 ultrasound system. A semiautomated analysis of GLS was performed after two-dimensional images were acquired in the standard apical 4-, 3- and 2 chamber views. MW and related indices were estimated using custom software.
Two groups were created according to the 17 segment model TTE study before LCZ696 therapy:
G1 (ischemic group): dyskinesia/akinesia/hypokinesia segments in patients with ischemic HF etiology;
G2 (non-ischemic group): normokinesia segments in patients with ischemic and all segments in patients with non-ischemic HF etiology;
Results
Of the 42 patients, 35 (83.3%) completed the six-months follow-up with LCZ696, since 2 patients (4.8%) died and 5 patients (11.9%) discontinued treatment for adverse events. Mean age was 58.6 ± 11.1 years, with ischemic etiology in 15 (42.9%), resulting in a total of 26.5% segments for G1.
Baseline global MW index (GWI) had no statistical difference between G1 and G2 (566.1 VS 584.8mmHg%, p = 0.257), but baseline MW efficiency (GWE) were significantly lower in G1 (71.9 VS 78.8%, p < 0.001).
The table represents the mean values for MW parameters in G1 and G2 before and 6 months after LCZ696 therapy, with a significantly increase in GWI and GWE values in both groups. Despite no difference in the increase in GWE (p = 0.872), the increase in GWI were higher in G2 than G1 (p < 0.001).
Conclusion
MW seems to be a new tool providing signs of reverse remodelling and better cardiac performance in ischemic and non-ischemic segments after LCZ696 therapy.

Abstract
Abstract
Introduction
Despite being the gold-standard for hemodynamic assessment, right heart catheterization (RHC) was overcome by plasma B-Type Natriuretic Peptide (BNP) levels in daily clinical routine. However, in the first year after heart transplantation (HT), the relationship between BNP and adverse hemodynamics have yielded conflicting results.
Purpose
The aim of this study was to evaluate whether BNP values can be used to estimate adverse hemodynamics in the first year after HT.
Methods
Prospective study of consecutive RHC performed in the first year after HT (according to the endomyocardial biopsies program). Plasma BNP levels were measured at the same day.
The area under the curve (AUC) was analysed to find the BNP values with higher sensitivity and specificity to detect adverse hemodynamics.
Results
From 2017 to 2018, 50 RHC were performed. Mean age was 48.7 ± 8.3 years, with mean BNP value of 964.4 ± 1114.7pg/ml.
Prediction of adverse hemodynamics by AUC results are represented in the table. BNP values were significantly increased in patients with pulmonary capillary wedge pressure (PCWP) >12mmHg (p < 0.001), cardiac index <2.5L/min/m2 (p = 0.001), mean pulmonary artery pressure (mPAP) ≥25mmHg (p < 0.001), pulmonary vascular resistance > 1,5WU (p = 0.044) and right atrial pressure >5mmHg (p = 0.003).
BNP >500pg/ml had a sensitivity of 78.3% and 87.5% and a specificity of 76.0% and 67.7% to detect PCWP >12mmHg and mPAP ≥25mmHg, respectively.
Conclusion Significant associations were found between BNP values and adverse hemodynamics in RHC, supporting the clinical utility of BNP in the first year after HT.

Abstract
Abstract
Introduction
Since the mid-1970s, the diagnosis of acute cellular rejection (ACR) has been made by endomyocardial biopsy (EMB). Whether B-Type Natriuretic Peptide (BNP), transthoracic echocardiography (TTE) parameters and right heart catheterization (RHC) parameters can detect rejection in heart transplant (HT) patients have yielded conflicting results and did not overcome the use of EMB in the first year after HT.
Purpose
The aim of this study was to evaluate whether BNP, TTE and RHC parameters can be used to detect ACR in the first year after HT.
Methods
Prospective study of consecutive EMB performed in the first year after HT. Plasma BNP levels, TTE and RHC were performed at the same day.
Clinical significant ACR was defined as ≥ 2R, according to the ISHLT 2004 grading. The area under the curve (AUC) was analysed for statistically significant associations to detect ACR.
Results
From 2017 to 2018, 50 EMB were performed with the following results: 2R - 5 (10.0%); 1R- 29 (58.0%); 0 – 16 (32%). Mean age was 48.7 ± 8.3 years, with mean BNP value of 964.4 ± 1114.7pg/ml.
AUC results of BNP and several TTE and RHC parameters for the prediction of ACR are represented in the table. Right atrial pressure (RAP) value (p = 0.027) was the only significantly predictor of ACR, while isovolumic relaxation time measured by TTE revealed a borderline significant trend (p = 0.076).
RAP > 10mmHg had a sensitivity of 60.0% and a specificity of 84.4% for detecting ACR.
Conclusion
Detecting ACR without EMB remains a clinical challenge, but RAP measured by RHC was a significant predictor of ACR in the first year after HT, while BNP values did not correlate with ACR.
