Abstract
Squamous cell carcinoma (SCC) stands as the second most prevalent skin cancer in dogs, primarily attributed to UV radiation exposure. Affected areas typically include regions with sparse hair and pale or depigmented skin. The significance of spontaneous canine cutaneous SCC as a model for its human counterpart is underscored by its resemblance. This study assesses the expression of key markers-Epidermal Growth Factor Receptor (EGFR), Cyclooxygenase-2 (Cox-2), and Ki-67-in canine cutaneous SCC. Our objective is to investigate the association between their expression levels and classical clinicopathological parameters, unraveling the intricate relationships among these molecular markers. In our retrospective analysis of 37 cases, EGFR overexpression manifested in 43.2% of cases, while Cox-2 exhibited overexpression in 97.3%. The EGFR, Cox-2 overexpression, and Ki-67 proliferation indices, estimated through immunohistochemistry, displayed a significant association with the histological grade, but only EGFR labeling is associated with the presence of lymphovascular emboli. The Ki-67 labeling index expression exhibited an association with EGFR and Cox-2. These findings propose that EGFR, Cox-2, and Ki-67 hold promise as valuable markers in canine SCC. EGFR, Cox-2, and Ki-67 may serve as indicators of disease progression, offering insights into the malignancy of a lesion. The implications extend to the potential therapeutic targeting of EGFR and Cox-2 in managing canine SCC. Further exploration of these insights is warranted due to their translational relevance and the development of targeted interventions in the context of canine SCC.

Abstract
Paleo-oncology studies neoplastic diseases in fossilised animals, including human remains. Recent advancements have enabled more accurate diagnoses of ancient pathologies despite the inherent challenges in identifying tumours in fossils-such as the rarity of well-preserved specimens, the predominance of bone remains, and the difficulty in distinguishing neoplastic from non-neoplastic lesions. This study compiles reports of tumours in fossilised animals, highlighting that neoplasms are present in a wide range of vertebrates and drawing comparisons to modern instances of similar diseases. The findings underscore the multifactorial aetiology of tumours, which involves genetic, environmental, and lifestyle factors, and suggest that tumours have been around for at least 350 million years.

Abstract
Equine melanomas are a common neoplasm in gray horses. However, scientific knowledge about their progression over time is quite scarce. Some owners and veterinarians still believe that early intervention is not necessary, stating that tumors evolve very slowly and intervention could worsen the animal's condition. This work aims to identify clinical and histological differences that may exist between equine melanomas with different excision intervals (time between tumor detection and surgical excision). A total of 42 tumors (13 benign and 29 malignant) from 34 horses were included in this study. There was a statistically significant association between excision interval and tumor size (p = 0.038), with tumors excised later being significantly larger than the ones excised sooner. The excision interval was also statistically associated with the number of tumors (p = 0.011), since the horses that carried a tumor for longer seemed to be prone to have multiple tumors. Furthermore, there was an association between excision interval and malignancy (p = 0.035), with tumor excised later being fives times more likely to be malignant. This study provides evidence of delayed excision's effect on the progression of equine melanomas. Additionally, it reinforces the importance of the early excision of these tumors.

Abstract
Background Respiratory diseases, including the multifactorial "swine respiratory disease complex," have a significant impact on swine production. Recently, a condition manifesting primarily in the trachea, known as hemorrhagic tracheitis syndrome (HTS), has been described in pigs. HTS is characterized by severe coughing and high mortality in finishing pigs. Case Description This report presents the first case of HTS in an adult male pig from a Portuguese farm. The animal died without any previous clinical signs. Necropsy revealed significant thickening of the trachea. Fibrinous necrotic hemorrhagic tracheitis was identified through histopathological analysis, but no bacterial infectious agents were detected during microbiological examination. Conclusion This case underscores the need for comprehensive research, including systematic necropsies and histopathological assessments, to understand the actual prevalence of the disease, elucidate the etiology, and develop effective interventions for HTS in swine productions.

Abstract
BACKGROUND Cyclo-oxygenase-2 (COX-2) and cancer associated fibroblasts (CAFs) play an important role in the development and progression of tumor malignancy in humans and animals, showing that both can influence the tumor microenvironment. However, the impact of these two markers in feline mammary carcinogenesis has not yet been addressed. MATERIALS AND METHODS In the present study, the clinicopathological significance of COX-2 immunoexpression and alpha-smooth muscle actin (α-SMA)-positive cancer-associated fibroblasts (CAFs) was determined and correlated with disease-free and overall survival of 50 felines with malignant mammary tumors. RESULTS COX-2 overexpression was positively associated with mitotic index (p=0.031), degree of malignancy (p≤0.001), lymph node metastasis (p≤0.001), vascular invasion (p=0.002), disease recurrence (p=0.019) and distant metastasis (p=0.036). α-SMA-positive CAFs were associated with mitotic index (p=0.004), lymph node metastasis (p=0.027), vascular invasion (p=0.05), disease recurrence (p≤0.001) and distant metastasis (p≤0.001). Additionally, both markers were correlated with disease-free and overall survival, emerging as predictors of poor prognosis. CONCLUSION Our results indicate for the first time that the presence of two markers, COX-2 and α-SMA, is associated with carcinogenesis and worse prognosis in feline mammary cancer and that α-SMA-positive CAFs have a role in feline mammary tumorigenesis, cancer development, and clinical outcome.

Abstract
Equine melanocytic tumors are common and have an unusual benign behavior with low invasiveness and metastatic rates. However, tumoral mass growth is usually a concern that can have life-threatening consequences. COX-2 is related to oncogenesis, promoting neoplastic cell proliferation, invasion, and metastasis. The aim of this study was to evaluate the immunohistochemical expression of COX-2 in equine melanocytic tumors. Through extension and intensity of labeling, 39 melanocytomas and 38 melanomas were evaluated. Of the malignant tumors, 13.2% were negative and 63.2% presented a low COX-2 expression. Only 6 malignant tumors presented >50% of labeled cells, 18 malignant and 8 benign had an expression between 21 and 50%, 8 malignant and 3 benign tumors had an expression between 6 and 20%, 1 malignant tumor had an expression between 1 and 5%, and 5 malignant and 28 benign tumors had no expression. Malignant tumors showed higher COX-2 expression than did benign tumors, with statistically significant differences. The low levels of COX-2 may be one of the molecular reasons for the presence of expansive mass growth instead of the invasive pattern of other species, which is related to high COX-2 levels.

Abstract
Transitional cell carcinoma of the urinary bladder is a significant neoplasm in dogs, characterized by a poor prognosis and a high metastatic potential. These canine spontaneous tumors share many characteristics with human transitional cell carcinoma, making them an excellent comparative model. The role of inflammatory infiltration in tumor development and progression is frequently contradictory, especially concerning tumor-associated tissue eosinophils (TATE) and tumor-associated macrophages (TAMs). This study aims to analyze TATE and TAMs in canine transitional cell carcinoma of the urinary bladder. Congo Red staining was used to identify TATE, and immunohistochemistry was performed to detect TAMs in 34 cases of canine transitional cell carcinoma of the bladder carcinomas, categorized into low and high grades. Statistically significant differences were observed between the number of eosinophils and macrophages in the two groups of tumors. The number of TATE was higher in low-grade malignant tumors, but the number of TAMs was higher in high-grade tumors. Our findings suggest the importance of TATEs and TAMs in the aggressiveness of canine transitional cell carcinoma and propose their potential use as therapeutic targets.

Abstract
Claw diseases have a profound impact on cattle welfare, affecting behaviors such as grazing, rumination, rest, decubitus, and water consumption. This study aimed to assess the prevalence of claw lesions and classify them according to the ICAR Claw Health Atlas (International Committee of Animal Recording) in two slaughterhouses. The influence of claw lesions on carcass weight, classification, and fat deposition was also examined. Involving 343 crossbreed cattle from 103 different extensive or semi-intensive farms, this study found an animal prevalence of claw disorders at 65.8%, with a higher incidence in females (n = 207, 60.35%) compared to males (n = 136, 39.65%). Despite the observed prevalence, claw lesions were not influenced by age or sex (p > 0.05). The main claw lesions identified, including heel horn erosion, double sole, and asymmetric claw, were consistent with the cattle management practices in the study area. These cattle were raised in small, rustic premises with uneven floors, utilizing a mix of manure and plant material as bedding and lacking access to pasture. Also, no negative economic impact was detected concerning carcass weight, classification, or fat deposition. Consequently, it was concluded that the presence of claw lesions in beef cattle raised under the characteristic management of this geographical area does not adversely affect animal health or farm economics.

Abstract
This article stems from interviews conducted with Chinese women residing in Lisbon, aged 18-34, during the initial phase of fieldwork (2021/2022). As an outcome of my Anthropology Ph.D. project, the focus here is on comprehending the perception of Asian women within the realm of everyday life as fetishized entities and how they persist in (re)shaping their identities. By primarily examining visual "yellow fever" depictions (in Hollywood cinema through films like "The World of Suzie Wong", "Madame Butterfly", "Miss Saigon", and the "Year of the Dragon", along with interracial Pornography), I endeavor to delve into the impact of "race", "sexual fetishization", and the ubiquitous propagation of stereotypical imagery on the lives of the individuals I engage with.

Abstract
Oral squamous cell carcinoma (OSCC) is a common and highly aggressive dog tumor known for its local invasiveness and metastatic potential. Understanding the molecular mechanisms driving the development and progression of OSCC is crucial for improving diagnostic and therapeutic strategies. Additionally, spontaneous oral squamous cell carcinomas in dogs are an excellent model for studying human counterparts. In this study, we aimed to investigate the significance of two key molecular components, Cox-2 and EGFR, in canine OSCC. We examined 34 tumor sections from various dog breeds to assess the immunoexpression of Cox-2 and EGFR. Our findings revealed that Cox-2 was highly expressed in 70.6% of cases, while EGFR overexpression was observed in 44.1%. Cox-2 overexpression showed association with histological grade of malignancy (HGM) (p = 0.006) and EGFR with vascular invasion (p = 0.006). COX-2 and EGFR concurrent expression was associated with HGM (p = 0.002), as well as with the presence of vascular invasion (p = 0.002). These data suggest that Cox-2 and EGFR could be promising biomarkers and potential therapeutic targets, opening avenues for developing novel treatment strategies for dogs affected by OSCC. Further studies are warranted to delve deeper into these findings and translate them into clinical practice.

Abstract
Currently available treatments for equine melanocytic tumors have limitations, mainly due to mass localization and dimension, or the presence of metastases. Therefore, a search for new therapies is necessary. Programmed cell death-ligand 1 (PD-L1) is expressed by several tumors, blocking T cell-mediated elimination of the tumor cells by binding to programmed cell death protein 1 (PD-1). A novel therapeutic approach using PD-1/PD-L1 blockade in human melanoma resulted in tumor regression and prolonged tumor-free survival. This study aimed to evaluate the immunohistochemical expression of PD-L1 in equine melanocytic tumors. A total of 77 melanocytic tumors were classified as benign or malignant and evaluated by extension of labeling. A total of 59.7% of the tumors showed >50% of immunolabeled cells. Regarding malignant tumors, 24/38 tumors presented >50% of labeled cells, 13 tumors presented between 25-50% and one tumor presented <10%. Regarding benign tumors, 22/39 tumors presented >50% of labeled cells, nine tumors presented 25-50%, three tumors presented 10-25%, two tumors presented <10% and three tumors did not present expression. Our results suggest that PD-L1 blockade may be a potential target for immunotherapy in equine melanocytic tumors and that future clinical research trials into the clinical efficacy of the anti-PD-L1 antibody are necessary.

Abstract
Antibiotic resistance is a global concern that affects not only human health but also the health of wildlife and the environment. Wildlife can serve as reservoirs for antibiotic-resistant bacteria, and antibiotics in veterinary medicine and agriculture can contribute to the development of resistance in these populations. Several European carnivore species, such as wolves, foxes, otters, and bears, can be exposed to antibiotics by consuming contaminated food, water, or other resources in their habitats. These animals can also be indirectly exposed to antibiotics through interactions with domestic animals and human activities in their environment. Antibiotic resistance in wildlife can harm ecosystem health and also impact human health indirectly through various pathways, including zoonotic disease transmission. Moreover, the spread of resistant bacteria in wildlife can complicate conservation efforts, as it can threaten already endangered species. This review aims to describe the presence of antibiotic-resistant bacteria in wild carnivores in Europe.

Abstract
Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now a rising concern in wildlife within Europe, after the detection of the first case in Norway in 2016, in a wild reindeer and until June 2022 a total of 34 cases were described in Norway, Sweden and Finland. The definite diagnosis is post-mortem, performed in target areas of the brain and lymph nodes. Samples are first screened using a rapid test and, if positive, confirmed by immunohistochemistry and Western immunoblotting. The study of the genetics of the prion protein gene, PRNP, has been proved to be a valuable tool for determining the relative susceptibility to TSEs. In the present study, the exon 3 of PRNP gene of 143 samples from red deer (Cervus elaphus) and fallow deer (Dama dama) of Portugal was analysed. Three single nucleotide polymorphisms (SNPs) were found in red deer - codon A136A, codon T98A, codon Q226E - and no sequence variation was detected in fallow deer. The low genetic diversity found in our samples is compatible with previous studies in Europe. The comparison with results from North America suggests that the free-ranging deer from our study may present susceptibility to CWD, although lack of experimental data and the necessity of continuous survey are necessary to evaluate these populations.

Abstract
Throughout the course of oncological disease, the majority of patients require surgical, anaesthetic and analgesic intervention. However, during the perioperative period, anaesthetic agents and techniques, surgical tissue trauma, adjuvant drugs for local pain and inflammation and other non-pharmacological factors, such as blood transfusions, hydration, temperature and nutrition, may influence the prognosis of the disease. These factors significantly impact the oncologic patient's immune response, which is the primary barrier to tumour progress, promoting a window of vulnerability for its dissemination and recurrence. More research is required to ascertain which anaesthetics and techniques have immunoprotective and anti-tumour effects, which will contribute to developing novel anaesthetic strategies in veterinary medicine.

Abstract
BACKGROUND In humans, muscle-invasive bladder cancer (MIBC) is highly aggressive and associated with a poor prognosis. With a high mutation load and large number of altered genes, strategies to delineate key driver events are necessary. Dogs and cats develop urothelial carcinoma (UC) with histological and clinical similarities to human MIBC. Cattle that graze on bracken fern also develop UC, associated with exposure to the carcinogen ptaquiloside. These species may represent relevant animal models of spontaneous and carcinogen-induced UC that can provide insight into human MIBC. RESULTS Whole-exome sequencing of domestic canine (n = 87) and feline (n = 23) UC, and comparative analysis with human MIBC reveals a lower mutation rate in animal cases and the absence of APOBEC mutational signatures. A convergence of driver genes (ARID1A, KDM6A, TP53, FAT1, and NRAS) is discovered, along with common focally amplified and deleted genes involved in regulation of the cell cycle and chromatin remodelling. We identify mismatch repair deficiency in a subset of canine and feline UCs with biallelic inactivation of MSH2. Bovine UC (n = 8) is distinctly different; we identify novel mutational signatures which are recapitulated in vitro in human urinary bladder UC cells treated with bracken fern extracts or purified ptaquiloside. CONCLUSION Canine and feline urinary bladder UC represent relevant models of MIBC in humans, and cross-species analysis can identify evolutionarily conserved driver genes. We characterize mutational signatures in bovine UC associated with bracken fern and ptaquiloside exposure, a human-linked cancer exposure. Our work demonstrates the relevance of cross-species comparative analysis in understanding both human and animal UC.

Abstract
Agonic aspiration of blood (AAB) may result from an inadequate exsanguination with accidental trachea severing, that can be favoured by ineffective stunning of pigs (Sus scrofa domesticus). This study aimed to evaluate AAB as an animal-based indicator of electrical stunning ineffectiveness, which could be used by official veterinarians during the post-mortem inspection of pigs. Information on 3584 finishing pigs was collected at a Portuguese abattoir that performs head-to-body electrical stunning with horizontal bleeding. Of them, 15.5% of the pigs presented signs of ineffective stunning. AAB lung lesions were found in 27.8% of lungs. Despite what was predicted, a strong correlation was found between well stunned animals and the presence of blood lesions in lungs (p = 0.006). Statistical significances were found between pigs' lateral recumbency at the conveyor and the presence of blood affecting one lung. Under the conditions of this study, the authors cannot point to AAB lung lesions as an animal-based indicator of electrical stunning ineffectiveness. Further studies should be conducted to establish a better understanding of the causes of aspiration of blood, in particular how horizontal bleeding may affect the occurrence of similar lesions.

Abstract
Melanocytic tumors are an important neoplastic disease in human and veterinary medicine, presenting large differences regarding tumor behavior between species. In horses, these tumors present a prolonged benign behavior, with rare invasiveness and metastases. In humans and small animals, invasion and metastasis have been associated with an Epithelial-Mesenchymal Transition, where the loss of E-cadherin expression plays a key role in tumor progression. This process and the role of E-cadherin have not yet been evaluated in equine melanocytic tumors. This study aimed to assess the immunolabeling of E-cadherin in equine melanocytic tumors and relate this with clinicopathological variables. A total of 72 equine melanocytic tumors were classified as benign and malignant and evaluated by immunohistochemistry for E-cadherin expression. A different pattern of immunostaining was found, contrasting with other species. A total of 69.4% of tumors presented raised immunolabeling of E-cadherin, with 70.7% of melanomas remaining with high expression. The typical loss of immunostaining was not seen in malignant melanomas and no differences were found between benign and malignant melanomas regarding E-cadherin immunostaining. The high immunolabeling of E-cadherin may contribute to the low invasiveness of these tumors, and it is in accordance with the benign behavior of equine melanoma and with the genetic factors associated with its development.

Abstract
Portugal is the habitat of three species of vultures. According to the IUCN Red List of Threatened Species, Neophron percnopterus is an Endangered species, Aegypius monachus is nearly Threatened, and Gyps fulvus is of Least Concern. This study aims to investigate the admission causes, morbidity, and outcomes of vultures admitted to a wildlife rehabilitation centre and necropsy service in Northern Portugal. Over 17 years (2005-2022), 84 animals were admitted: 10 A. monachus, 69 G. fulvus, and 5 N. percnopterus. The main causes of admission to the centre were 80% (n = 63) unknown cause, 13% (n = 10) found debilitated, 6 % (n = 5) vehicle collision, 4% (n = 3) captivity, 1% (n = 1) gunshot, and 1% (n = 1) electrocution. Most animals were admitted during the summer (45.2%) and autumn (36.9%). Analysis of outcome data showed that 73% (n = 58) of the animals that arrived alive at the centre could be rehabilitated and released back into the wild. Thirteen animals died during treatment and five were found dead. This is the first time that such a lengthy study of results and mortality has been carried out for these species in Portugal. Although the data are limited, they can already provide some information about these populations, particularly for the endangered species that are so rare to observe.

Abstract
Abnormal prion proteins (PrPSc) are the disease-associated isoform of cellular prion protein and diagnostic markers of transmissible spongiform encephalopathies (TSEs). These neurodegenerative diseases affect humans and several animal species and include scrapie, zoonotic bovine spongiform encephalopathy (BSE), chronic wasting disease of cervids (CWD), and the newly identified camel prion disease (CPD). Diagnosis of TSEs relies on immunodetection of PrPSc by application of both immunohistochemistry (IHC) and western immunoblot methods (WB) on encephalon tissues, namely, the brainstem (obex level). IHC is a widely used method that uses primary antibodies (monoclonal or polyclonal) against antigens of interest in cells of a tissue section. The antibody-antigen binding can be visualized by a color reaction that remains localized in the area of the tissue or cell where the antibody was targeted. As such, in prion diseases, as in other fields of research, the immunohistochemistry techniques are not solely used for diagnostic purposes but also in pathogenesis studies. Such studies involve detecting the PrPSc patterns and types from those previously described to identify the new prion strains. As BSE can infect humans, it is recommended that biosafety laboratory level-3 (BSL-3) facilities and/or practices are used to handle cattle, small ruminants, and cervid samples included in the TSE surveillance. Additionally, containment and prion-dedicated equipment are recommended, whenever possible, to limit contamination. The PrPSc IHC procedure consists of a formic acid epitope-demasking step also acting as a prion inactivation measure, as formalin-fixed and paraffin-embedded tissues used in this technique remain infectious. When interpreting the results, care must be taken to distinguish non-specific immunolabeling from target labeling. For this purpose, it is important to recognize artifacts of immunolabeling obtained in known TSE-negative control animals to differentiate those from specific PrPSc immunolabeling types, which can vary between TSE strains, host species, and prnp genotype, further described herein.

Abstract
Every year tons of heavy metals, plastic, pesticides, industrial chemicals, and sewage reach the oceans. Many of these compounds are not biodegradable and have a prolonged half-life, occurring and causing effects even several years after application. The consequences are diverse as biomagnification of toxins, infertility, neoplasia, hormonal alteration, or malformations. Sentinel species can be barometers for current or potential negative impacts on individuals, animal populations and ecosystem health, helping to identify hidden risks to human health and predict future changes. Several bioindicators allow us to evaluate the status of ecosystems, echinoderms are some of them. Their diversity of habitats, diet, sensibility to changes in the environment and position of the trophic chain makes them one the most ideal marine sentinels. This paper aims to present a summarized review with the latest information available that is related to the echinoderms as a sentinel of human, animal and environmental health.

Abstract
A local drug delivery system that attempts to find a suitable balance between antimicrobial and regenerative actions was developed for osteomyelitis treatment (OM). This system combines the angiogenic and immunomodulatory peptide LLKKK18 (LL18) and vancomycin hydrochloride (VH), loaded into an injectable oxidized dextrin (ODEX)-based hydrogel (HG). In vitro cytotoxicity was analyzed in MC3T3-E1 pre-osteoblasts and erythrocytes. The kinetics of LL18 release was studied. Antimicrobial activity was assessed in vitro against a clinical Methicillin-Resistant Staphylococcus aureus (MRSA) strain. A rat model of acute OM was developed by direct inoculation into a tibia defect, concomitantly with the implantation of the drug-loaded HG. The local bioburden was quantified and damage in surrounding tissues was examined histologically. In vitro, ODEX-based HG displayed a safe hemolytic profile. Half of LL18 (53%) is released during the swelling phase at physiological pH, then being gradually released until complete HG degradation. LL18-loaded HG at 300 μM was the most effective peptide formulation in decreasing in vivo infection among concentrations ranging from 86 to 429 μM. The histopathological scores observed in vivo varied with the LL18 concentration in a dose-dependent manner. VH at 28 mM completely eradicated bacteria, although with substantial tissue injury. We have found that sub-millimolar doses of VH combined with LL18 at 300 μM may suffice to eradicate the infection, with reduced tissue damage. We propose an easy-to-handle, shape-fitting HG formulation with the potential to treat MRSA-infected bone with low VH doses associated with LL18.

Abstract
Cell secretome has been explored as a cell-free technique with high scientific and medical interest for Regenerative Medicine. In this work, the secretome produced and collected from Olfactory Mucosa Mesenchymal Stem Cells and Olfactory Ensheating Cells was analyzed and therapeutically applied to promote peripheral nerve regeneration. The analysis of the conditioned medium revealed the production and secretion of several factors with immunomodulatory functions, capable of intervening beneficially in the phases of nerve regeneration. Subsequently, the conditioned medium was applied to sciatic nerves of rats after neurotmesis, using Reaxon® as tube-guides. Over 20 weeks, the animals were subjected to periodic functional assessments, and after this period, the sciatic nerves and cranial tibial muscles were evaluated stereologically and histomorphometrically, respectively. The results obtained allowed to confirm the beneficial effects resulting from the application of this therapeutic combination. The administration of conditioned medium from Olfactory Mucosal Mesenchymal Stem Cells led to the best results in motor performance, sensory recovery, and gait patterns. Stereological and histomorphometric evaluation also revealed the ability of this therapeutic combination to promote nervous and muscular histologic reorganization during the regenerative process. The therapeutic combination discussed in this work shows promising results and should be further explored to clarify irregularities found in the outcomes and to allow establishing the use of cell secretome as a new therapeutic field applied in the treatment of peripheral nerves after injury.

Abstract
Abstract
Background
Takayasu’s arteritis (TA) is a systemic inflammatory disease that affects aorta and its major branches. There are several cardiac manifestations of TA and, recently, an association with Takotsubo syndrome (TTS) was reported
Case Presentation
A 58–year–old Caucasian female, with history of severe asymptomatic aortic regurgitation (AR) with a recently documented normal LV systolic function and TA in remission under corticosteroids, was admitted in the emergency department with chest pain following an acute intense stressful event. ECG showed sinus tachycardia, T wave inversion in left precordial and lateral leads, and a QTc of 487 ms (Figure 1). Laboratorial evaluation presented high–sensitivity troponin I of 3494 ng/L and B–type natriuretic peptide of 4759 pg/mL. The transthoracic echocardiogram revealed severe dilation of LV with moderate systolic dysfunction, due to apical and midventricular akinesia (“apical ballooning” pattern), and severe AR (Figure 2). The coronary angiography showed normal coronary arteries. An acetylcholine provocative test showed spasm of both the left anterior descending and circumflex arteries, accompanied by chest pain and ST depression in ECG, reverted after intracoronary nitrates administration (Figure 3). The patient was switched to diltiazem and heart failure drug therapy was started. A cardiac magnetic resonance revealed severe dilation of the LV, apical hypokinesia, ejection fraction to 53%, signs of myocardial edema and increased extracellular volume in apical and mid–ventricular anterior and anterolateral walls, and absence of myocardial late gadolinium enhancement, compatible with TTS. Patient was discharged clinically stable, without signs of HF, with progressive reduction of troponin and BNP. A final diagnosis of myocardial infarction with nonobstructive coronary arteries (MINOCA) due to TTS and coronary vasospasm in a patient with TA was done
Discussion
TA is a rare disease and there are reports of its association both with TTS and coronary vasospasm. Besides that, coronary vasospasm may also be involved in the pathophysiology of TTS. Moreover, in this patient we could not exclude the role coronary diastolic hypoperfusion due to AR in the elicitation of coronary vasospasm. Therefore, although the mechanisms behind these pathologies are not yet fully studied, this case supports their relationship
Conclusion
We presented a case of a patient with TA admitted with MINOCA due to TTS and coronary vasospasm

Abstract
Abstract
Background
Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg–Strauss, is a rare multisystem disorder characterized by chronic rhinosinusitis, asthma, and prominent peripheral blood eosinophilia (PE). Cardiac involvement may include eosinophilic myocarditis and it is a serious manifestation of EGPA.
Case Presentation
A 67–year–old woman presented to the emergency department with 2–weeks history of dyspnea, orthopnea and asthenia. She had history of asthma, PE, adjuvant radiotherapy after right mastectomy (July 2021). The patient was diagnosed with new onset atrial fibrillation in the previous month. At admission, the patient was hemodynamically stable and with signs of congestion. Complementary exams showed sinus rhythm and T–wave inversion on lateral leads; PE (2010/uL), elevated troponin and BNP values; and severe biventricular systolic dysfunction with diffuse hypokinesia and apical akinesia. The patient was admitted to the ICU and was treated with intravenous diuretics and levosimendan. Optimal HF therapy was introduced. Serial echocardiography revealed partial recovery of LVEF and blood analysis showed a decrease in troponin levels, with persistent eosinophilia (6330/uL). Computed tomography (CT) excluded significant coronary disease, and showed bilateral basal ground–glass opacities, areas of air–space consolidation and bilateral reticular–nodular pattern. Cardiac magnetic resonance revealed increased T2 values/signs of myocardial edema in anterior wall, interventricular septum and apex and no late gadolinium enhancement, compatible with myocarditis. An endomyocardial biopsy (EMB) was performed and confirmed the diagnosis of eosinophilic myocarditis. Oral corticosteroids were started. Paranasal CT scan showed signs of chronic sinusitis, without polyposis, and antineutrophil cytoplasmic antibodies were positive, making the diagnosis of EGPA, according to ACR criteria.
Discussion
In a patient presenting with new onset heart failure and with history of asthma and eosinophilia, it is important to suspect eosinophilic myocarditis, as this is a rare but reversible life–threatening condition. EMB plays an important role in the diagnosis and should be done promptly.
Conclusion
We described a multidisciplinary management of a case of a patient with eosinophilic myocarditis and EGPA, presenting with severe acute biventricular dysfunction.

Abstract
Cancer registries are fundamental tools for collecting epidemiological cancer data and developing cancer prevention and control strategies. While cancer registration is common in the human medical field, many attempts to develop animal cancer registries have been launched over time, but most have been discontinued. A pivotal aspect of cancer registration is the availability of cancer coding systems, as provided by the International Classification of Diseases for Oncology (ICD-O). Within the Global Initiative for Veterinary Cancer Surveillance (GIVCS), established to foster and coordinate animal cancer registration worldwide, a group of veterinary pathologists and epidemiologists developed a comparative coding system for canine neoplasms. Vet-ICD-O-canine-1 is compatible with the human ICD-O-3.2 and is consistent with the currently recognized classification schemes for canine tumors. It comprises 335 topography codes and 534 morphology codes. The same code as in ICD-O-3.2 was used for the majority of canine tumors showing a high level of similarity to their human counterparts (n = 408). De novo codes (n = 152) were created for specific canine tumor entities (n = 126) and topographic sites (n = 26). The Vet-ICD-O-canine-1 coding system represents a user-friendly, easily accessible, and comprehensive resource for developing a canine cancer registration system that will enable studies within the One Health space.

Abstract
Vet-OncoNet is a replicable tripartite animal cancer database with the scientific and academic purposes of collecting data and producing evidence-based knowledge for cancer science in general. Inspired by the One Health vision, Vet-OncoNet uses business intelligence tools to optimize the process of capturing, treating, and reporting animal cancer data to a national level in three interfaces: ACR (animal cancer registry, pathology-based), COR (clinical oncology registry, vet practice-based) and RFR (risk factor registry, owner-based). The first results show that skin and mammary gland are by far the most affected systems. Mast cell tumors and complex adenoma of the mammary gland are the most frequent histologic type in dogs, while in cats they are squamous cell carcinomas, tubular adenocarcinoma of the mammary gland and lymphomas. Regarding COR, it provides valuable information on the landscape of veterinary oncology practices, therapeutics options, outcomes and owners’ drivers’ adherence towards therapies, which range from 30% up to 80% upon vet practices. Furthermore, being aware of the role of animals within the family and as possible sentinels of environmental risks to cancer in humans, the network built an interface (Pet-OncoNet) dedicated to owners and a database (RFR) that receives information regarding pets and owners’ daily habits.

Abstract
Wasting disease in small ruminants is frequently detected at slaughterhouses. The wasting disorder is manifested by the deterioration of the nutritional and physiological state of the animal indicated by thinness, emaciation, and cachexia. Evidence of emaciation and cachexia, alone, are pathological conditions leading to carcass condemnation during an inspection. Several diseases are associated with a wasting condition, including scrapie, pseudotuberculosis, tuberculosis, paratuberculosis, Maedi Visna, and tumor diseases. On the other hand, parasitic diseases, nutrition disorders, exposure or ingestion of toxins, metabolic conditions, inadequate nutrition due to poor teeth, or poor alimentary diet are conditions contributing to poor body condition. Classical and atypical scrapie is naturally occurring transmissible spongiform encephalopathies in small ruminants. The etiological agent for each one is prions. However, each of these scrapie types is epidemiologically, pathologically, and biochemically different. Though atypical scrapie occurs at low incidence, it is consistently prevalent in the small ruminant population. Hence, it is advisable to include differential diagnosis of this disease, from other possibilities, as a cause of wasting conditions detected during meat inspection at the abattoir. This manuscript is a review of the measures in force at the abattoir for scrapie control, focusing on the differential diagnosis of gross lesions related to wasting conditions detected in small ruminants during meat inspection.

Abstract
Abstract
Introduction
Patients hospitalized due to acute heart failure (AHF) compose a heterogeneous population whose prognosis is difficult to forecast. Previously, BAUN score has proven to be able to accurately predict in-hospital mortality (IHM) in AHF. We aimed to evaluate BAUN score performance in the prediction of long-term outcomes in this population, comparing it to the recently validated Get With The Guidelines (GWTG) score.
Methods
A retrospective analysis of 1052 patients admitted to a Cardiology ward due to AHF was performed. 268 patients were excluded due to data omission or therapy with sacubitril/valsartan. Using the variables systolic blood pressure, urea, brain natriuretic peptide and sodium at admission, BAUN score was calculated, ranging from 0–28 points. GWTG score was also calculated at the index event. ROC curve analysis was used to compare the predictive value of the two scores for IHM. Kaplan-Meyer and Cox-regression analysis were performed to evaluate BAUN score prediction ability for 24-month mortality (24-MM) and for the composite endpoint of 24-month rehospitalization or death (24-MH).
Results
Mean patient age was 77 (±10) years; 51% were men. Mean left ventricle ejection fraction (EF) was 49% (±16.4). An EF<40% was present in 31% of patients. IHM, 24-MM and 24-HM were 6.5%, 17.1% and 57.8%, respectively. Mean BAUN score was 7 (±5.64). Mean GWTG score was 49.7 (±9.8). ROC curve analysis for IHM prediction revealed a better performance of the BAUN score (AUC: 0.738p, <0.001) in comparison with GWTG score (AUC: 0.687, p<0.001). Patients were stratified into subgroups according to BAUN risk score – very-high risk (≥22), high risk (16–21), intermediate risk (5–15) and low risk (<5). Kaplan-Meyer analysis revealed a significant difference in 24-MM according to risk subgroup (very high: 35%, high: 26.7%, intermediate: 19.5%, low risk: 12.7%, χ2=16.304, p=0.001). When stratified by non-reduced or reduced EF (≥40% or <40%), there was still a significant mortality difference in subgroups with reduced (p=0.007) and borderline significant in patients with nonreduced EF (p=0.05). Kaplan-Meyer analysis also revealed a significant difference between subgroup risk for 24-MH (51%; 63.8%; 63.3% and 75%, respectively, for low, intermediate, high and very-high risk, χ2=21.237, p<0.001). Cox regression analysis demonstrated that BAUN score independently predicts 24-MM (HR: 1.056, p=0.043) and 24-MH (HR: 1.033, p=0.048), even after adjustment for other prognostic markers, such as atrial fibrillation, coronary artery disease, previous myocardial infarction, age, EF and GWTG score.
Conclusion
BAUN outperforms GWTG score for IHM prediction in AHF. It also independently predicts 24-MM and 24-MH. Its use may identify patients with high risk of mortality/readmission, in need of specialized care, and those patients with low risk of death, who might be candidates for lenient surveillance.

Abstract
Abstract
Introduction
Intermediate risk pulmonary embolism (PE) encompass a heterogeneous group of patients with very distinct prognosis. While some patients will only need anticoagulation, in others fibrinolytic therapy (FT) should be considered in order to prevent further hemodynamic decompensation. It is very important to identify the subgroup of intermediate risk PE patients at highest risk of an adverse outcome in whom FT may be needed. Modified FAST score was developed to identify non-high risk PE patients at highest risk of early PE-related complications. This study aims to evaluate if modified FAST score is a predictor of necessity of FT.
Methods
A retrospective analysis of 178 patients admitted for acute PE was performed. Modified FAST score evaluates the presence of syncope (1.5 points), troponin I elevation (1.5 points) and heart rate ≥100bpm (2 points), ranging from 0–5 points (<3 points low risk and ≥3 points intermediate-high risk for adverse in-hospital outcome). PESI score was also calculated for each patient. The Mann-Whitney U was used for comparisons between groups. Binary logistic regressions were used to obtain the odds ratio (OR) for FT of the various variables. ROC curves allowed the comparison of modified FAST and PESI scores.
Results
Mean age was 63±18 years; 61% were female; 8.5% had previous history of venous thromboembolism; 48% of patients had a precipitating factor identified; 58% had signs of right ventricle dilation on echocardiography (echo) and/or chest computed tomography (CCT). 47% had low risk (LR) and 53% had intermediate-high risk (IHR), according to modified FAST score. Mean FAST score was 2.22±1.4.
There were no differences between patients with LR or IHR regarding age, sex and precipitating factor. IHR was associated with dyspnea (p=0.002), lower arterial systolic pressure at admission (p=0.007), higher levels of D-dimer (p=0.013), S1Q3T3 pattern (p=0.001) and right bundle branch block pattern (p=0.005) in electrocardiography and higher right ventricle diameter in echo and CCT (p=0.006).
During hospitalization patients with IHR had more worsening of renal function (p=0.015).
Patients with IRH were submitted more frequently to FT than patients with LR (65% vs 39%; p=0.001). Modified FAST score was a predictor of FT (OR 2.9; 95% CI 1.5–5.5; p<0.001) and was independent of PESI score (OR 2.9; 95% CI 1.5–5.6; p=z0.001). ROC curve analysis revealed a higher area under the curve for modified FAST score comparing to PESI score (0.659 vs 0.497).
Conclusion
IHR modified FAST score was associated with characteristics of poor prognosis in PE. Furthermore, modified FAST score was a predictor of FT in normotensive patients with PE, and was independent of PESI score. Therefore, this score may be useful to select patients with PE that will benefit from FT.

Abstract
Abstract
Introduction
Acute coronary syndrome (ACS) is a clinical entity which includes a heterogeneous group of patients with different outcomes. Risk scores are in this setting a resourceful tool to identify the subset of patients with a worse prognosis, in order to plan therapeutic and surveillance strategies.
Aim
To create a risk score – Laboratory Risk Score (LRS) – which exclusively includes analytical and echocardiographic parameters, as a predictor of adverse outcomes (in-hospital mortality and 1-year mortality), and compare it with other well-known scores: GRACE Score (GS) and TIMI-score (TS).
Methods
A retrospective cohort study was conducted, which included patients admitted in the Cardiology Department with the diagnosis of ACS. In order to calculate the new LRS, the authors attributed the value of 1 to each of the satisfied condition from the following: leucocytes >11,7g/L, hemoglobin <13.3g/dL, red cell distribution width >14%, prothrombinemia <90%, glycaemia at admission >143mg/dL, urea >53.5mg/dL, creatinine >1.16mg/dL, reactive C-protein >1.0mg/dL, maximum troponin >35.0ng/dL, natriuretic brain peptide >416 pg/dL and left ventricular ejection fraction <40%. LRS resulted from the sum of the satisfied conditions.
ROC curves for LRS, GS and TS to predict in-hospital mortality and to predict 1-year mortality were constructed. The statistical analysis was performed in SPSS and Medcalc. p value <0.05 was considered statistically significant.
Results
1714 patients (70.4% male, average age 69±13 years-old) were included in this study. Intra-hospital mortality rate was 6.8% and 1-year mortality rate after de discharge was 4.8%.
The areas under the ROC curves for predicting in-hospital mortality were the following: 0,790 (LRS, p<0,001), 0,793 (GS, p<0.01), 0.817 (TS, p<0.001). For predicting 1-year mortality, the areas under the ROC curves were: 0,715 (LRS, p<0,001), 0,761 (GS, p<0,001), 0.742 (TS, p<0.001). Pairwise comparison of ROC curves showed no significant differences between the scores.
Conclusion
The above-mentioned risk scores, including the new LRS, are obtained with non-invasive and widely available parameters and displayed a good performance in predicting in-hospital and 1-year mortality. Pairwise comparison of ROC curves demonstrated that the new laboratorial score was not inferior predicting adverse outcomes. The SRL is an easily obtained score, that shows a statistical significance in predicting mortality, especially the prediction of in-hospital mortality.

Abstract
Abstract
Introduction
Global longitudinal strain (GLS) is considered a more sensitive marker of systolic dysfunction than other measures commonly used in clinical practice, such as left ventricle ejection fraction (EF). Our objective was to evaluate the impact of reduced GLS in death and cardiovascular events in patients hospitalized due to heart failure with mid-range or preserved ejection fraction, with previous history of acute myocardial infarction.
Methods
A retrospective analysis of 170 patients admitted to a Cardiology ward due to acute heart failure (AHF) was performed. Patients with reduced EF (Simpson biplane method - EF<40%) were excluded based on echocardiographic evaluation after AHF stabilization. GLS measured by “speckle tracking” technique was calculated for each patient. Measurements were made by the same operator to minimize interoperator variability. Mann-Whitney U test was used for univariate analysis. Kaplan-Meier survival plots and Cox-regression analysis were performed to assess differences in 12-month mortality (12MM) and in the composite endpoint of cardiovascular event or death (12CVM) at 12 months.
Results
A total of 127 patients were included. Mean patient age was 64 (±14) years; 72% were men. 48% of patients had history of ST elevation AMI. Mean EF was 54% (±8) and mean GLS was −14.3 (±3.8). Rates of 12MM and 12CV M were 14.2% and 19.3%, respectively. A statistically significant association between 12MM and 12MCV was found in univariate analysis for GLS (p<0.001). Kaplan-Meyer survival plots revealed that a compromised GLS (<−16) was associated with significantly increased 12MM (23% vs 2.5%, X2: 7.999, p=0.005) and 12CVM (26.6% vs 10%, X2: 4.139, p=0.042). When stratified by mid-range vs preserved EF, GLS <−16 was associated with worse outcomes, although the results did not reach statistical significance (p>0.05). However, when considering a severely compromised GLS (<−13), GLS was significantly associated with increased 12MM (52% vs 8.3%, X2: 5.533, p=0.019) and 12CVM (50% vs 8.3%, X2: 4.970, p=0.026), in the subgroup of patients with heart failure with mid-range EF. Cox-regression analysis demonstrated that GLS was independently associated with 12MM (HR: 0.668p, <0.001) and the 12CVM composite endpoint (HR: 0.819, p=0.008), even after adjustment for other important prognostic markers such as chronic kidney disease, pulmonary disease and diabetes, with significant hazard ratio reduction for each positive point increase in GLS.
Conclusion
GLS is an independent predictor of 12MM and 12CVM in patients hospitalized due to AHF, with an EF ≥40% and previous history of acute myocardial infarction. In the subgroup of patients with heart failure with mid-range EF, a severely compromised GLS (<−13) is a strong predictor of 12MM and 12CVM.

Abstract
Abstract
Introduction
Patients hospitalized due to heart failure (HF) constitute a heterogeneous population whose prognosis is difficult to forecast. The purpose of this study was to create a model based on simple bedside recordable echocardiographic, analytical and objective clinical parameters that could accurately predict mortality and/or rehospitalization risk in different stages of HF course.
Methods
A retrospective analysis of 347 patients admitted to a Cardiology ward due to decompensated HF was performed. The echocardiographic variables pulmonary artery systolic pressure (PSAP) and E/e' ratio, and the analytical/clinical variables systolic blood pressure (SBP), urea and brain natriuretic peptide (BNP) were selected for inclusion. Subgroups were created for each variable and an odds ratio (OR) for the risk of in-hospital mortality (IHM) was calculated. A numerical value proportional to the OR was attributed to each subgroup. A score was created, ranging from 0–47 points, corresponding to the sum of the classification attributed to each variable. ROC curve analysis was used to assess predictive value of the score for IHM. Kaplan-Meyer and Cox-regression plots were used to assess mortality (24MM) and the composite endpoint of HF rehospitalization or death at 24 months (24HM).
Results
Mean patient age was 78 (±9) years; 51% were men. Score variable means were - PSAP: 47 (±15) mmHg; E/e': 16.8 (±7.8); SPB: 138 (±31) mmHg; Urea: 71 (±35) mg/dl; BNP: 911 (±995) pg/ml. Mean ejection fraction (EF) was 48% (±16). 35% of patients had EF<40%. IHM, 24MM and 24HM were 3.5%, 17.1% and 63.6%, respectively. A statistically significant association between IHM and PSAP, E/e', BNP, urea and SBP (p<0.05) was found on univariate analysis. ROC curve analysis of AHFM revealed an AUC of 0.785 (p=0.001) for IHM risk prediction. The cut-off point with most sensitivity (S) and specificity (E) obtained using the Youden index (0.4246) was 18 (S≈75%; E≈67%), associated with significant difference in IHM (1.3% vs 7.6%). IHM by score interval was 1.3%, 3.1% and 25%, respectively, for the intervals 0–18, 19–29 and ≥30. ECHO-AHF score <13 predicted in-hospital survival in all patients. Kaplan Meyer survival analysis by subgroup revealed significant differences in 24MM according to AHFM risk category (13.8% vs 21.9% vs 30.8%, respectively, χ 2= 17.217 p<0.001), but not for 24 MH. Cox-regression analysis demonstrated that AHFM score remained a significant independent predictor of 24MM (HR: 1.067, p=0.05), even after adjustment for other variables, such as coronary disease, chronic kidney disease, atrial fibrillation, EF and diabetes.
Conclusion
AHFM score is an accurate model for predicting IHM and long-term risk of HF death. Its use may help to identify patients with high risk of mortality, in need of specialized care, and those with lower risk of death, who might be candidates for early discharge or lenient follow-up.

Abstract
Abstract
Introduction
Left Ventricular Non-Compaction (LVNC) is a rare and underdiagnosed cardiomyopathy, characterized by hypertrabeculation of the left ventricle. This disease is associated with high rates of morbidity and mortality; however, its main adverse prognostic factors are not well established.
Aim
To create a risk score for LVNC based on echocardiographic criteria (EcoScore) to predict the occurrence of adverse events.
Methods
The authors included patients with the diagnosis of LVNC, according to the Jenni Criteria. Clinical and echocardiographic data were evaluated and the occurrence of the following adverse events was reported: hospitalizations due to supraventricular or ventricular tachyarrythmias and heart failure, acute myocardial infarction, stroke, heart transplant and death. The follow-up time was 24 months. ROC curves to predict the occurrence of at least one adverse event were constructed for each echocardiographic parameter. The optimal cut-off obtained from each ROC curve was then used to attribute points (1 point per parameter). The EcoScore resulted from the sum of the obtained points. The authors finally created a ROC curve to predict the occurrence of any adverse event for the EcoScore. The statistical analysis was performed in SPSS. p value <0.05 was considered statistically significant.
Results
33 patients (48.5% male, age at diagnosis 45.9±21 years) were included in this study. The optimal cut-offs for each parameter obtained from the ROC curves were the following: left ventricle dyastolic diameter >55mm, left atrial diameter >40mm, pulmonary artery systolic pressure >22mmHg and left ventricle ejection fraction <40%. The area under the curve for the EcoScore to predict any adverse event was 0.850 (p=0.017) and an EcoScore >1 had a sensibility of 85.7% and a specificity of 70%.
Conclusion
The EcoScore accurately predicted the occurrence of at least one adverse event in this population. Thus, it could be a good tool in the daily practice to select patients who may benefit from a more aggressive surveillance and treatment.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of dalbavancin against MRSA biofilm-related infection in orthopaedic implants in vivo. METHODS One MRSA strain isolated from human osteomyelitis was used to promote biofilm formation on the surface of screws. The implants were inserted in the proximal tibia under general anaesthesia. Thirty-nine Wistar rats were divided into three groups [control group (no treatment), Group 1 (7 days of treatment) and Group 2 (14 days of treatment)]; both treatment groups were administered dalbavancin intraperitoneally and euthanized after treatment. cfu of bacteria present in both the tibia and the implant were quantified. The infection severity was assessed by histopathology and scored from 0 (no infection) to 4 (severe infection). RESULTS The high number of cfu/g and cfu/mL present in the control group indicated a well-established infection. There was a significant reduction in cfu in rats treated with dalbavancin both in the tibia (2.8 × 105 cfu/g) and the implant (1.1 × 106 cfu/mL) in Group 1 (1.8 × 103 cfu/g and 2.4 × 105 cfu/mL, respectively) and in Group 2 (8.2 cfu/g and 8.2 × 103 cfu/mL, respectively). Most animals from the control group presented an infection scored as 3 (severe). At the end of the experiment, most rats from Groups 1 and 2 presented an infection scored as 2 (moderate) and 0 (no infection), respectively. CONCLUSIONS Although there was a marked decrease in cfu number, signs of biofilm-induced infection prevailed after 14 days of treatment. Further studies should be carried out to evaluate the potential of dalbavancin in the treatment of bone and orthopaedic implant-associated MRSA infections.

Abstract
BACKGROUND/AIM Canine Cutaneous Histiocytoma (CCH) is a Langerhans' cells benign tumour that undergoes spontaneous regression. The aim of the present study was to investigate the role of angiogenesis, a key step for tumour development, in CCH regression. MATERIALS AND METHODS 50 CCH samples were classified into 4 histological groups according to a regression scale, and evaluated for expression of vascular endothelial factor-A (VEGF-A) and its receptor VEGFR-2 as well as microvessel density (MVD). RESULTS Tumours during early stages of the regressive process had a lower MVD compared to later stages, while CCH tumoural cells showed a limited production of VEGF, but higher levels of VEGFR-2. On the contrary, tumours in advanced phases of regression showed a higher number of neovessels, probably associated with the inflammatory state and the healing process. CONCLUSION Our results suggest that angiogenesis may be compromised at early stages of histiocytoma development and this may be a determinant of regression in this tumour.

Introduction
Individualized estimation of prognosis after cardiac resynchronization therapy (CRT) remains challenging. Outcomes in this group of patients are influenced by multiple factors and a comprehensive and customized approach to estimate prognosis after CRT is lacking
Aims
To develop and validate a simple prognostic score for patients implanted with CRT (NISAR-F score), based on readily available clinical and echocardiographic variables to predict the combined endpoints of death or hospitalization in 24 months.
Methods
A single-centre retrospective study was conducted with inclusion of all consecutive patients who underwent CRT implantation between 2012 and 2019. Follow-up started after CRT implantation and ended upon death, hospitalization or 24 months after study entry. Survival analysis was performed using a multivariate Cox regression model, in order to analyze the effect on survival /hospitalization in 24 months of the following factors: age, gender, NYHA Class III-IV, ischemic heart failure, type 2 diabetes, arterial hypertension, dyslipidemia and ejection fraction < 21%. According to the analysis, points were attributed to each factor. Afterwards, the NISAR-F score was calculated for each patient, summing the points of each variable. The authors finally created ROC curves for the NISAR-F score to predict the occurrence of the combined endpoint in 2 groups of patients: CRT responders (ejection fraction increase of at least 10% after CRT implantation) and CRT non-responders. The statistical analysis was performed in SPSS.
Results
102 patients were included in the study (75.4% male, mean age 68 ± 10.46 years). 10(9.8%) of the patients were re-hospitalized and 8 (7.8%) died during the 24-month follow-up. After calculating NISAR-F score for each patient, area under ROC curves were obtained. The analysis of the ROC curves allows us to confirm the good performance of the score created [responders group (AUC 0.812) vs non-responders (AUC 0.721)].
Conclusion The NISAR-F score is a useful tool to predict the combined endpoint (mortality and hospitalization in 24 months) after CRT implantation, in both responders and non-responders, revealing good performance of this new and simple score based only on clinical and echocardiographic variables.

Introduction
Several studies have suggested a relationship between dyslipidemia and atherogenesis, which displays a main role in the pathophysiology of Acute Coronary Syndrome (ACS).
Aim
To compare the lipid profile between younger (<55 years) and older (≥55 years) patients admitted due to ACS.
Methods
A single-centre retrospective study was conducted, with inclusion of all consecutive patients admitted in the Cardiology Department due to ACS. Several analytical parameters were evaluated, including total cholesterol (CT), HDL cholesterol (HDL), LDL cholesterol (LDL) and triglycerides (TG) and CT/HDL, LDL/HDL and TG/HDL ratios were calculated. All parameters are presented in mg/dL. Afterwards, comparison of these data between younger (age < 55 years, Group-A) and older (age≥55 years, Group-B) patients was done. Statistical analysis was performed with SPSS and a p value < 0.05 was considered statistically significant.
Results
1168 patients (70.1% male, mean age 69 ±12 years) were included in this study. 15.8% of patients were from Group-A. Mean levels of the analysed parameters were the following: CT 176 ± 55, LDL 111 ± 45, HDL 40 ± 12 and TG 137 ± 102. The following mean ratios were obtained: CT/HDL 4.6 ± 1.9, LDL/HDL 2.9 ± 1.4 and TG/HDL 3.8 ± 3.5. Comparison of the analysed parameters and calculated ratios is exhibited in table 1.
Conclusion
Overall, a worse lipid profile was observed in younger patients. This data reveals the role of dyslipidemia in coronary heart disease, which displays a main role in atherosclerosis at a younger age. This fact highlights the importance of adopting a healthy lifestyle and the adherence to primary and secondary prevention measures of cardiovascular events.
Lipid profile: young vs old patient Group A Group B Total Cholesterol 199 ± 44 170 ± 56 p < 0.001 LDL Cholesterol 128 ± 37 107 ± 46 p < 0.001 HDL Cholesterol 39 ± 10 40 ± 12 p = 0.307 Triglycerides 195 ± 189 125 ± 66 p < 0.001 CT/HDL 5.3 ± 1.5 6.8 ± 2.0 p < 0.001 LDL/HDL 3.4 ± 1.1 2.8 ± 1.4 p < 0.001 TG/HDL 5.6 ± 6.3 3.5 ± 2.5 p < 0.001

Introduction
Several studies have concluded that smoking increases mortality in patients with coronary disease. On the other hand, a J-shaped dose-effect curve has been used to describe the relationship between alcohol and cardiovascular mortality. According to the majority of studies, a moderate intake of alcohol is associated with a decrease in mortality, while an excessive alcohol intake appears to increase mortality.
Aim
To evaluate the effect of smoking and excessive alcohol intake in hospital mortality and 1-year mortality in patients hospitalized due to acute coronary syndrome (ACS).
Methods
A single-centre retrospective study was conducted, with inclusion of all consecutive patients admitted in the Cardiology Department due to ACS. Follow-up started after hospital admission and ended upon hospital death, death within the following 12 months or 12 months after study entry. Patients were divided in two groups: smokers (Group-A) and non-smokers (Group-B), to analyse the effect of smoking in hospital mortality and 1-year mortality. To analyse the effect of excessive alcohol intake, patients were also divided in other two groups: Group-C (excessive drinkers) and Group-D (non-excessive drinkers). Statistical analysis was performed with SPSS and a p value < 0.05 was considered statistically significant.
Results
1120 patients (68.9% male, mean age 69.12 ± 12.67 years) were included in this study. 20.5% were smokers and 3.2% had a previous excessive alcohol intake.
Between Group-A and Group-B, a statistically significant difference was observed in gender (93.1% male in Group-A vs 62.9% male in Group-B, p = 0.002), but not in age (p = 0.116). Hospital mortality rates in Group-A and Group-B were respectively 6.0% and 8.7% (p = 0.191) and 1-year mortality rates were 3.1% vs 5.1% (p = 0.239).
Between Group-C and Group-D, a statistically significant difference was observed in gender (94.4% male in Group-C vs 69.8% male in Group-B, p < 0.001), but not in age (p = 0.730). Hospital mortality rates in Group-C and Group-D were respectively 25% and 9.6% (p = 0.003) and 1-year mortality were 3.8% vs 6.6% (p = 0.577).
Conclusions
Smoking did not have a positive or negative effect in hospital mortality and 1-year mortality. However, excessive alcohol intake was associated with increased hospital mortality in this population.

Abstract
The data from 78 native species of reptiles and amphibians admitted to the Wildlife Rehabilitation Center of Parque Biológico de Gaia (Portugal) from 2009 to 2017 were revised to determine the main causes of morbidity and mortality. These data include four different orders: order Squamata (51.3%), order Testudinata (12.8%), order Anura (12.8%), and order Caudata (2.6%). 92.3% of the considered admittances were adults arriving during spring (41%) and autumn (29.5%). The main causes of admission to Rehabilitation Center were animals debilitated (12.8%) and injured (66.7%). Trauma was the major cause of mortality (78.2%). Unknown origin was the main cause of traumatic (71.8%) and non-traumatic (9.0%) death, followed by captivity related lesions (6.4%). These animals are excellent bioindicators of the health of the ecosystem and enable the identification of the main threats affecting them, especially those of anthropogenic origin. Studies of mortality on wild reptiles and amphibians are important to understand which the main threats and how human activity is affecting these populations.

Abstract
The presence of methicillin-resistant Staphylococcus aureus (MRSA) in bone infections difficults its treatment and is a sign of concern. The aim of this study was to evaluate in vitro activity of dalbavancin on pre-established adhered cells and 24 h old biofilms of MRSA strains isolated from a human bone infection. Thirty-three MRSA were isolated from osteomyelitis episodes. The antimicrobial susceptibility of these strains was assessed by the Kirby-Bauer disc diffusion method and the presence of resistance genes was screened by PCR. MRSA planktonic minimum inhibitory concentration and minimum bactericidal concentration were assessed. Minimum biofilm eradication concentration (MBEC) was performed by the microtiter biofilm formation assay. All 33 MRSA strains were classified as multidrug-resistant strains and susceptible to dalbavancin. Dalbavancin inhibited the growth of 54.6% and 52% of strains at the concentrations of 0.05 µg/mL and 1 µg/mL, respectively. The MBEC values up to 0.4 µg/mL demonstrated that dalbavancin was active against most strains in pre-established adhered cells and 24 h old biofilms. The current results show that dalbavancin is active against adhered cells and biofilms in vitro, suggesting that this antimicrobial agent may be an option for the treatment of bone infections caused by MRSA.

Abstract
OBJECTIVE The CLOSER (CLarifying Vaginal Atrophy's Impact On SEx and Relationships) survey investigated how postmenopausal vaginal atrophy (VA) affects relationships between Brazilian women and male partners. METHODS Postmenopausal women (age 55-65 years) with VA, and male partners of women with the condition, completed an online survey on the impact of VA and local estrogen treatment on intimacy and relationships. RESULTS A total of 360 women and 352 men from Brazil were included. Women (83%) and men (91%) reported that they were comfortable discussing VA with their partners. Women's key source of information on VA was health-care providers (HCPs), but 44% felt that not enough information is available. VA caused 70% of women to avoid sexual intimacy and resulted in less satisfying sex. VA had a negative impact on women's feelings and self-esteem. Women (76%) and men (70%) both reported that treatment with vaginal estrogen improved their sexual relationship, primarily by alleviating women's pain during sex. Women (56%) and men (59%) felt closer to each other after treatment. CONCLUSIONS VA had a negative impact on sexual relationships for both women and men in Brazil, and reduced women's self-confidence. Vaginal hormone therapy improved couples' sexual relationships. A proactive attitude of HCPs is essential to educate women on VA and the potential benefits of treatment.

Abstract
PURPOSE This study aims to analyze the retinal layers and choroidal thickness in a large set of eyes with early age-related macular degeneration (AMD), in order to detect differences by stage suggestive of early neurodegeneration, and to explore biomarkers of different phenotypes. METHODS This study is a population-based, cross-sectional study. Patients from the incidence AMD study (NCT02748824) with early AMD (Rotterdam 2a, 2b, 3) were included. All performed spectral-domain optical coherence tomography (SD-OCT) (Spectralis, Heidelberg Engineering, Germany) and automatic segmentation of all retinal layers was obtained with built-in software. Manual correction was performed whenever necessary. The mean thicknesses (ETDRS grid) and volume of each layer were recorded. Subfoveal choroidal thickness was manually measured. Estimates for each layer thickness were calculated with linear mixed models and tested for pairwise differences between stages. Associations between layer thickness and microstructural findings were assessed by multivariate regression analysis. RESULTS The final cohort comprised 346 eyes (233 patients): 82.66% (n = 286) in stage 2a, 5.49% (n = 19) in stage 2b, and 11.85% (n = 41) in stage 3. A global tendency for lower/inferior thickness of the neuroretinal layers was found comparing stage 3 to 2a: retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and inner plexiform layer (IPL) were inferior in the inner/outer ETDRS circles and the outer nuclear layer (ONL) and photoreceptors' segments layer in the central circle (p ≤ 0.002). The retinal pigment epithelium-Bruch's membrane (RPE/BrM) layer was thicker in stage 3 (p ≤ 0.001). Subretinal drusenoid deposits (SDD) were associated with thinner neuroretinal layers and choroid (p < 0.05). CONCLUSIONS Our results showed in a large population-based dataset that several inner and outer neuroretinal layers were thinner with a higher stage in early AMD. These findings support the existence of early and progressive neurodegeneration. Neuronal retinal layer thicknesses might thus be used as quantitative biomarkers of disease progression in AMD. The presence of SDD is possibly associated to more prominent and faster neurodegeneration.

Abstract
Blood leukocyte counts and respective derived ratios have been described as potential prognostic markers in several tumours in veterinary oncology. This study aimed to evaluate peripheral blood leukocyte subpopulations and neutrophil-to-lymphocyte ratio (NLR) as prognostic factors for feline mammary carcinomas (FMC). Medical records from cats diagnosed with FMC between 2017 to 2019 were reviewed. Cats were included if fully staged, classified as WHO stage I to III, and submitted to mastectomy. Cats were excluded if they had evidence of other diseases. Forty-nine cats were included. The study endpoints were disease-free interval (DFI) and tumour-specific survival (TSS). The median DFI and TSS were 389 days and 528 days respectively. In the univariate analysis, higher values of total white blood cell count (WBC), neutrophil count (NEU) and NLR were identified as significant prognostic factors for both endpoints (P < .05). On the multivariate analysis, NLR remained an independent prognostic factor for TSS (P = .024). In the receiver operating characteristic curve analysis, the estimated cut-off for WBC was 8.49 × 109 /L (DFI and TSS); for NEU was 4.62 × 109 /L (DFI) and 6.65 × 109 /L (TSS) and for NLR was 2.46. These cut-offs were significant prognostic factors for DFI and TSS (P < .05). NLR cut-off remained an independent prognostic factor for both DFI (P = .032) and TSS (P = .043) in the multivariable analysis. Our results suggest that NLR, NEU, and WBC can be important non-invasive presurgical prognostic markers, and that NLR is an independent prognostic marker for FMC. Prospective studies are warranted to validate its clinical use.

Abstract
Cyclooxygenase (COX) isoforms-1 and -2 have been extensively investigated in cancer. Although COX-2 is the isoform most studied and has been described in several malignancies associated with histologic criteria of malignancy and worse prognosis, COX-1 has also been linked to some forms of cancer. With the present review our aim was to summarize the current state of knowledge and clarify if and in which type of tumours COX-1 and/or COX-2 expression have real prognostic implications. We searched PubMed database for prognostic studies using predefined inclusion criteria in order to ascertain the prognostic value of COX-1 and COX-2 in malignant neoplasia in dogs and cats. Eighteen studies were analysed. COX-2 was shown to be a negative prognostic factor in canine and feline mammary tumours, canine mast cell tumour, canine melanoma, canine osteosarcoma and canine renal cell carcinoma. COX-1 showed a negative prognostic value in feline oral squamous cell carcinoma (SCC). We found high heterogeneity among studies regarding COX immunohistochemical evaluation methodology even in the same type of neoplasia pointing out the need for its standardization at least by tumour type. The available data support the use of COX-2 as a prognostic factor in canine (mammary carcinoma, mast cell tumour, melanoma, osteosarcoma and renal carcinoma) and feline (mammary carcinoma) cancers. For COX-1, its use is advised in feline oral SCC.

Abstract
Background and Aim: Wild mammals are among the most threatened species of the world in large part due to human activity. In this work, we used the method of partial least squares-path modeling associated with a geographic information system to analyze the impact of anthropogenic pressures on the mortality of wild mammals. Materials and Methods: We collected the data related to the cause of death of native wild mammals admitted to the Wildlife Rehabilitation Centre of Parque Biológico de Gaia in Northern Portugal, during 10 years (2008-2017). Results: A total of 359 animals from 42 municipalities (rural and urban areas) were included in the study. The main cause of death was of traumatic origin. From the anthropogenic pressures included in the study, water reservoirs, small companies, and residential buildings were the ones that contributed the most to increase the mortality of traumatic and non-traumatic origin. This relation of cause-effect (mortality-anthropogenic pressures) was supported by the high coefficients of determination obtained (R2 > 0.8). Conclusion: The present results allow a general view on the reality of mammal’s mortality in Northern Portugal. Furthermore, it could also constitute a valuable tool for the conservation of wild mammals in those areas.
