Abstract
Glioblastoma (GBM) is the most prevalent malignant primary brain tumor and currently lacks an effective treatment. In this study, we utilized a microfluidic system to synthesize docosahexaenoic acid (DHA) liposomes for GBM therapy. DHA is an omega-3 (ω3) polyunsaturated fatty acid commonly found in human dietary consumption that has demonstrated potential in mitigating cancer development. The microfluidic device employed allowed for precise fine-tuning of the physicochemical properties of liposomes by adjusting the flow rate ratios, flow rates, and lipid concentrations. Three distinct-sized liposomes, ranging from 80 nm and 130 nm, were successfully internalized by GBM cells, and demonstrated the ability to reduce the viability of these cells. Furthermore, DHA liposomes proved significantly more efficient in triggering apoptotic pathways, through caspase-3-dependent mechanisms, in comparison to free DHA. Thus, the nanomedicine platform established in this study presents new opportunities in the development of liposome formulations incorporating ω3 fatty acids for cancer therapy.

Abstract
Sacrocolpopexy is considered as the "gold standard" for management of women with apical prolapse. Numerous technical variants are being practiced. The first aim of this survey was to determine the habits of practice of laparoscopic sacrocolpopexy (LSCP) in Europe. The second aim was to determine whether surgeons who perform laparoscopic pelvic organ prolapse (POP) repair are familiar with the practice of alternative techniques and with mesh-less laparoscopic treatment of prolapse. The questionnaire was designed by the Urogynaecology Special Interest Group of the European Society for Gynaecological Endoscopy (ESGE). All ESGE-members were invited by email to respond to this survey consisting of 54 questions divided in different categories. Following review of ESGE member's responses, we have highlighted the great heterogeneity concerning the practice of LSCP and important variability in performance of concomitant surgeries. Alternative techniques are rarely used in practice. Furthermore, the lack of standardisation of the many surgical steps of a laparoscopic sacrocolpopexy is mainly due to the lack of evidence. There is a need for training and teaching in both standard and newer innovative techniques as well as the reporting of medium and long-term outcomes of both standard laparoscopic sacrocolpopexy and any of its alternatives.

Abstract
Xanthomonas citri subsp. citri is the cause of bacterial citrus canker, responsible for major economic losses to the citrus industry. X. citri subspecies and pathovars are responsible for diseases in soybean, common bean, mango, pomegranate, and cashew. X. citri disease has been tracked using several typing methods, but recent studies using genomic sequencing have been key to understanding the evolutionary relationships within the species, including fundamental differences among X. citri subsp. citri pathotypes. Here, we describe a core-genome multilocus sequence typing (cgMLST) scheme for X. citri based on 250 genomes comprising multiple examples of X. citri subsp. citri pathotypes A, A*, and Aw; X. citri subsp. malvacearum; X. citri pv. aurantifolii, pv. fuscans, pv. glycines, pv. mangiferaeindicae, pv. viticola, and pv. vignicola; and single isolates of X. citri pv. dieffenbachiae and pv. punicae. This data set included genomic sequencing of 100 novel X. citri subsp. citri isolates. cgMLST, based on 1,618 core genes across 250 genomes, is implemented at PubMLST (https://pubmlst.org/organisms/xanthomonas-citri/). GrapeTree minimum-spanning tree and Interactive Tree of Life (iTOL) neighbor-joining phylogenies generated from the cgMLST data resolved almost identical groupings of isolates to a core-genome single nucleotide polymorphism (SNP)-based neighbor-joining phylogeny. These resolved identical groupings of X. citri subsp. citri pathotypes and X. citri subspecies and pathovars. X. citri cgMLST should prove to be an increasingly valuable resource for the study of this key species of plant-pathogenic bacteria. Users can submit genomic data and associated metadata for comparison with previously characterized isolates at PubMLST to allow the rapid characterization of the local, national, and global epidemiology of these pathogens and examine evolutionary relationships. IMPORTANCE Xanthomonas citri is a plant pathogen that causes major economic losses to the citrus industry and sweet orange production in particular. Several subspecies and pathogens are recognized, with host ranges including soybean, common bean, mango, pomegranate, and cashew, among others. Recent genomic studies have shown that host-adapted X. citri subspecies and pathovars and X. citri subsp. citri pathotypes form distinct clades. In this study, we describe a core-genome multilocus sequence typing (cgMLST) scheme for this species that can rapidly and robustly discriminate among these ecologically distinct, host-adapted clades. We have established this scheme and associated databases containing genomic sequences and metadata at PubMLST, which users can interrogate with their own genome sequences to determine X. citri subspecies, pathovars, and pathotypes. X. citri cgMLST should prove to be an invaluable tool for the study of the epidemiology and evolution of this major plant pathogen.

Abstract
Glioblastoma (GBM) is a highly aggressive malignant brain tumor currently without an effective treatment. Inspired by the recent advances in cell membrane biomimetic nanocarriers and by the key role of macrophages in GBM pathology, we developed macrophage membrane liposomes (MML) for GBM targeting. For the first time, it was assessed the role of macrophage polarization states in the effectiveness of these drug delivery systems. Interestingly, we observed that MML derived from M2 macrophages (M2 MML) presents higher uptake and increased delivery of the anticarcinogenic drug doxorubicin compared to M1 macrophage-derived nanocarriers (M1 MML) and control liposomes (CL). Moreover, the lowest uptake by macrophages of MML reveals promising immune escaping properties. Notably, M2 macrophages unveiled a higher expression of integrin CD49d, a crucial protein involved in the bilateral communication of macrophages with tumor cells. Therefore, our findings suggest the potential of using M2 macrophage membranes to develop novel nanocarriers targeting GBM.

Abstract
Introduction Due to the Covid-19 effects, mental health conditions are now, more than ever, affecting our daily lives - both personally and professionally. The average delay between the onset of first symptoms of a mental health disorder and seeking suitable healthcare is 11 years. The WHO states that the only sustainable way to reduce mental healthcare burden is by acting earlier. Objectives The aim of this project is to assess the receptivity and engagement of a mobile app for mental health prevention, amongst a large-scale and heterogeneous group of individuals. The main hypothesis under testing is that people are receptive to actively act towards mental health prevention, despite still being a very neglected and stigmatized topic. Methods A mobile app for mental health improvement and disease prevention was developed through the digitalization of positive psychology strategies, such as mood tracking, journaling, breathing exercises, among others, which are personalized to the user through biofeedback. The app aims at teaching people how to autonomously cope with mental health conditions, identifying early signs and redirecting them to proper mental health professionals. The app is being released for a population of 35,000 subjects resident in Portugal. Results Receptivity and engagement metrics will be assessed on a weekly and monthly basis, for 3 months, segmented by different subject profiles. Mental health metrics will also be assessed, namely anxiety, depression, and burnout levels - using standard psychiatric scales. Conclusions We have yet to draw conclusions from the project; however, we aim to achieve first results in due time. Disclosure The aim of this research is to assess the receptivity of mental health prevention strategies using technology, namely a mobile app provided by a company.

Abstract
Effective and safe therapies to counteract persistent inflammation are necessary. We developed erythrocyte-derived liposomes (EDLs) with intrinsic anti-inflammatory activity. The EDLs were prepared using lipids extracted from erythrocyte membranes, which are rich in omega-3 fatty acids with several health benefits. Diclofenac, a widely used anti-inflammatory drug, was incorporated into EDLs in relevant therapeutic concentrations. The EDLs were also functionalized with folic acid to allow their active targeting of M1 macrophages, which are key players in inflammatory processes. In the presence of lipopolysaccharide (LPS)-stimulated macrophages, empty EDLs and EDLs incorporating diclofenac were able to reduce the levels of important pro-inflammatory cytokines, namely interleukin-6 (IL-6; ≈85% and 77%, respectively) and tumor necrosis factor-alpha (TNF-α; ≈64% and 72%, respectively). Strikingly, cytocompatible concentrations of EDLs presented similar effects to dexamethasone, a potent anti-inflammatory drug, in reducing IL-6 and TNF-α concentrations, demonstrating the EDLs potential to be used as bioactive carriers in the treatment of inflammatory diseases.

Abstract

Type of funding sources: None.
Background
Platypnea-orthodeoxia syndrome (POS) is an uncommon condition characterized by dyspnoea and hypoxemia in the upright position that improves with recumbency.1 Possible causes are intracardiac shunt, pulmonary arteriovenous shunt, and V/Q mismatch.1,2 Echocardiography is the cornerstone of POS diagnosis, with special focus on atrial septal defect (ASD) morphology and right-to-left shunt confirmation.3
Purpose
To evaluate the clinical and echocardiographic features of patients presenting with POS due to a cardiac cause.
Methods
We performed a retrospective analysis of patients diagnosed with POS in our centre between 2015 January and 2021 August. Routine blood tests and transthoracic echocardiogram (TTE) were performed in all patients. Demographics, clinical presentation, blood test results, TTE information, and PFO closure procedure details were recorded.
Results
Seven patients were included, 85.7% female (n = 6). The median (IQR) age was 78 (72-85) years. The most prevalent cardiovascular risk factors were hypertension (100%; n = 7) and overweight/obesity (85.7%; n = 6). Two patients (28.6%) had chronic pulmonary disease. The most common symptoms were fatigue and exercise intolerance (n= 5; 71.4%) and the most frequent sign was persistent hypoxemia (n = 7; 100%), although 28.6% (n = 2) patients did not present the typical positional changes in peripheral oxygen saturation. Haemoglobin levels [14.1 (13.3-15.2)] were within the normal range and serum NTproBNP levels [656 (287-1196)] were slightly elevated. Left ventricle function was preserved in all patients; right ventricle morphology and function were normal in 85.7% (n = 6) patients, low probability of pulmonary hypertension in TTE was found in 85.7% (n = 6), and exuberant Eustachian valve was observed in 14.3% (n = 1). All patients presented atrial septal hypermobility, 87.5% (n = 6) meeting atrial septal aneurysm criteria. Patent foramen ovale was found in 85.7% of patients (n = 6) and ostium secundum ASD in 14.3% (n = 1). POS precipitating factors were aortic root dilation (28.6%; n = 2), chest trauma (14.3%; n = 1), right hip arthroplasty (14.3%; n = 1), atrial septal stretching regarding right volume overload (14.3%; n = 1). The underlying mechanism was unknown in 28.6% (n = 2) of patients. ASD closure was performed in 57.1% (n = 4) of patients: 75% (n = 3) showed residual shunt, but clinical improvement was reported by all. No acute complications were described, except for paroxysmal atrial fibrillation (14.3%; n = 1).
Conclusion
POS diagnosis depends on high clinical suspicion: the most common manifestations are fatigue and persistent hypoxemia. Typical positional changes in oxygen saturation are not present in all patients. Polycythaemia, right chambers dilation, and pulmonary hypertension are not common. Echocardiography is fundamental for diagnosis, allowing right-to-left shunt confirmation and ASD morphology evaluation to outline a successful closure procedure.

Abstract
Background Whilst some imaging signs of endometriosis are common and widely accepted as ‘typical’, a range of ‘subtle’ signs could be present in imaging studies, presenting an opportunity to the radiologist and the surgeon to aid the diagnosis and facilitate preoperative surgical planning. Objective To summarise and analyse the current information related to indirect and atypical signs of endometriosis by ultrasound (US) and magnetic resonance imaging (MRI). Methods Through the use of PubMed and Google scholar, we conducted a comprehensive review of available articles related to the diagnosis of indirect signs in transvaginal US and MRI. All abstracts were assessed and the studies were finally selected by two authors. Results Transvaginal US is a real time dynamic exploration, that can reach a sensitivity of 79-94% and specificity of 94%. It allows evaluation of normal sliding between structures in different compartments, searching for adhesions or fibrosis. MRI is an excellent tool that can reach a sensitivity of 94% and specificity of 77% and allows visualisation of the uterus, bowel loop deviation and peritoneal inclusion cysts. It also allows the categorisation and classification of ovarian cysts, rectovaginal and vesicovaginal septum obliteration, and small bowel endometriotic implants. Conclusion The use of an adequate mapping protocol with systematic evaluation and the reporting of direct and indirect signs of endometriosis is crucial for detailed and safe surgical planning.

Abstract
In this study, a microfluidic device was employed to produce polymeric nanoparticles (NPs) with well-controlled sizes. The influence of several parameters in the synthesis process, namely, polymer concentration, flow rate and flow rate ratio between the aqueous and organic solutions was investigated. To evaluate the NPs size effect, three diameters were selected (30, 50 and 70nm). Their cytocompatibility was demonstrated on endothelial cells and macrophages. Additionally, their efficacy to act as drug carriers was assessed in an in vitro inflammatory scenario. NPs loaded and released diclofenac (DCF) in a size-dependent profile (smaller sizes presented lower DCF content and higher release rate). Moreover, 30nm NPs were the most effective in reducing prostaglandin E2 concentration. Therefore, this study demonstrates that microfluidics can generate stable NPs with controlled sizes, high monodispersity and enhanced batch-to-batch reproducibility. Indeed, NPs size is a crucial parameter for drug encapsulation, release and overall biological efficacy.

Abstract
AIMS The aim of the study is to evaluate hexanoic acid (HA) as an alternative to manage citrus canker. METHODS AND RESULTS The minimal growth inhibitory concentration of HA against Xanthomonas citri subsp. citri was determined at 2·15 mmol l-1 using a respiratory activity assay. Growth curves at different pH values showed that growth inhibition was not due to media acidification induced by HA. The germination rate and root elongation of Lactuca sativa seeds exposed to different concentrations of HA (varying from 0·86 to 5·16 mmol l-1 ) were assessed to screen for phytotoxicity. The acid exhibited low phytotoxicity for L. sativa at 1·29 and 2·58 mmol l-1 . To evaluate the ability of HA to protect citrus against X. citri infection, leaves of Citrus sinensis were sprayed with the acid and subsequently challenged with X. citri. HA at 3·44 mmol l-1 was able to protect citrus against infection, showing a reduction of three orders of magnitude in the number of citrus canker lesions per cm2 when compared to the untreated negative control. CONCLUSION HA is a potential alternative to copper for citrus canker management. SIGNIFICANCE AND IMPACT OF THE STUDY HA inhibits X. citri growth, exhibits low phytotoxicity and is an alternative to copper for the protection of citrus plants against bacterial infection.

Abstract
Worldwide uptake of new drugs in the treatment of rifampicin-resistant tuberculosis (RR-TB) has been extremely low. In June 2018, ahead of the release of the updated WHO guidelines for the management of RR-TB, South Africa announced that bedaquiline (BDQ) would be provided to virtually all RR-TB patients on shorter or longer regimens. South Africa has been the global leader in accessing BDQ for patients with RR-TB, who now represent 60% of the global BDQ cohort. The use of BDQ within a shorter modified regimen has generated the programmatic data underpinning the most recent change in WHO guidelines endorsing a shorter, injectable-free regimen. Progressive policies on access to new drugs have resulted in improved favourable outcomes and a reduction in mortality among RR-TB patients in South Africa. This supported global policy change. The strategies underpinning these bold actions include close collaboration between the South African National TB Programme and partners, introduction of new TB diagnostic tools in closely monitored conditions and the use of locally generated programmatic evidence to inform country policy changes. In this paper, we summarise a decade´s work that led to the bold decision to use a modified, short, injectable-free regimen with BDQ and linezolid under carefully monitored programmatic conditions.

Abstract
Introduction The Eye Movement Desensitization and Reprocessing (EMDR) therapy has shown to be useful in the treatment of PTSD, general anxiety, stress and burnout. Nonetheless, assessing therapy progress has been limited to subjective appreciations of the patient and therapist, which compromise therapy efficacy, and the continuum of care (clinic and at home) and scalability that digitized approaches can offer. Objectives The aim of the present study was to validate the potential of a smartphone-based biofeedback digitized approach for EMDR usage in burnout therapy, as a means to provide quantitative progress assessment and personalized therapy optimization. Methods A digitized burnout status assessment app based on Maslach Burnout Inventory was first implemented and tested. Then, an EMDR app was developed by making use of adjustable audiovisual stimuli (e.g. different velocity and horizontal/vertical visual stimuli; and different pitch and left-right surround sound effects) and also of the smartphone’s camera photoplethysmography finger recordings from which heart rate, heart rate variability and breathing rate are derived and used for modulating stimuli (biofeedback). Finally, interviews with several EMDR experts were conducted to assess the potential of the app as a therapeutic adjuvant. Results The preliminary interview results showed that the app can be useful for online therapy, to optimize the stimuli presentation, and to quantify the therapy experience and outcomes. The interviews also validated the technical specifications and usability of the tool. Conclusions Results so far have shown a promising receptivity and interest from EMDR experts. As such, patient testing is currently on-going. Disclosure The work of the present abstract is the basis of the research conducted at the Faculty of Sciences of the University of Lisbon, co-lead with NEVARO, a spin-off company of the same Faculty.

Abstract
BACKGROUND Endometriosis is likely to affect sexuality and intimate relationships but the effect endometriosis has on partners remains overlooked and the existing studies show conflicting results. The effect of the disease and its treatment on the couple may be pronounced given the absence of an obvious cause or cure, the likelihood of chronic recurring symptoms, and the potential impact on both sex and fertility. MATERIALS AND METHODS We followed the PRISMA guidelines to conduct this systematic review, which involved a database search of published available research related to the effects of endometriosis treatment on sexual function, couple's relationship and on the partner published between 2000 and 2020. RESULTS The studies considered revealed that women with endometriosis report a significant effect of the disease on sexuality and relationship. Also, most of the published studies suggest that the impact on partners may be profound, affecting many life domains including sex, intimacy and the relationship in general. CONCLUSIONS Data suggests that male partners should not be overlooked in the treatment of endometriosis and that psychosocial support including sexual and couple therapy might be beneficial.

Abstract
BACKGROUND Deep endometriosis most commonly involves the rectosigmoid junction and its management often requires a colorectal resection. Anastomotic leakage is a severe complication after resection and affects 1-6% of the cases. OBJECTIVE To evaluate the risk factors related to anastomotic leakage following endometriosis sur-gery, its prevention techniques and the role of protective stomas. METHODS A comprehensive literature review was carried out for English-language publications in Pubmed and Google Scholar. We included all studies including the following MeSH terms and key words: Anastomotic leakage AND bowel surgery OR Endometriosis OR Colorectal surgery OR Bowel endometriosis. Two authors independently made a selection and analysed relevant abstracts according to the aim of this review. RESULTS Risk factors and preventive measures were categorised considering the patient condition, the intra- operative setting and the surgical procedure itself. Level I and II recommendations include modifiable risk factors such as the use of stapled or handsewn anastomosis; intra-operative air leak test to check the integrity of the anastomosis; systematic use of pelvic and trans-anal drainage; application of protective or ghost ileostomy in low rectal resections; vaginal closure before the bowel resection; use of oral antibiotics the day before surgery and performing partial mesorectal resection near the bowel wall. Diverting stomas may decrease the morbidity and the clinical consequences of leakage over 65% of low rectal resections but may cause significant adverse effects. CONCLUSION Evidence-based protective actions are crucial to reduce clinical consequences of anastomotic leakage and to minimise the use of protective stomas in endometriosis surgery.

Abstract
Abstract
Introduction One of the main etiological agents of respiratory infections is H. Influenzae. The group of antibiotics most used to the treatment of H. influenzae infections is β-lactams. The most common β-lactam resistance is to ampicillin, characterized by the production of TEM (95%) and ROB (5%) β-lactamases, designated enzymatic resistance.
Objectives Characterize the susceptibility profile of H. influenzae to β-lactam antibiotics, to evaluate the enzymatic resistance by the β-lactamase production and to correlate the phenotypic profile with the presence of the blaTEM.
Methodology Total of 152 isolates of H. influenzae from respiratory infections were evaluated: 88 from expectorations, 56 from bronchial aspirates and 8 from bronchoalveolar lavage, collected in Clinical Pathology Service of Centro Hospitalar e Universitário de Coimbra. The results of the antimicrobial susceptibility profile and the β-lactamase screening were also provided. In order to investigate the blaTEM, DNA was extracted from the isolates and the detection was performed using the PCR technique.
Results The prevalence of the blaTEM in the isolates was 31.6%, of these 33.3% showed resistance to ampicillin and 57.9% were positive in β-lactamase activity screening and blaTEM carriers. There was a statistically significance between the presence of the gene with ampicillin resistance and β-lactamase activity screening.
Conclusion β-lactamase TEM production was the main mechanism of enzymatic resistance which demonstrates the high spread of the blaTEM among isolates of H. influenzae. The results found suggest that the negative strains for this β-lactamase but that presented β-lactamases with activity and resistance to β-lactams should have other β-lactamases as ROB or others. However strains with β-lactamase negative should have other mechanisms promoting the resistance as PBP3. This study provides important data on the antibiotic therapy, to minimize the expression of resistance mechanisms and problems associated with treatment.

Abstract
Abstract
Mitral regurgitation severity is, in accordance to current recommendations, typically evaluated by echocardiography. Several hemodynamic factors may influence this evaluation, especially systemic arterial blood pressure at the time of echocardiographic evaluation.
A 71-year-old woman was admitted in our Cardiology ward with acute decompensated heart failure. She had been previously admitted about 3 months earlier by acute decompensated heart failure, and at that time, admission transthoracic echocardiography (TTE) demonstrated mitral regurgitation, which was evaluated as severe. Systolic systemic arterial blood pressure at the time of that TTE was registered as 135mmHg. For further evaluation of mitral regurgitation mechanism, the patient underwent transoesophageal echocardiography (TEE), and in that exam mitral regurgitation was assessed as only moderate. For that exam, patient was sedated with 5mg of intravenous Midazolam, a drug with known secondary hypotensive effect. Although systemic arterial blood pressure was not described in the TEE report, retrospective analysis of nursery blood pressure records showed that patient was hypotensive during exam with systolic arterial blood pressure of 80-90mmHg. Patients was discharged, and in actual admission, concern was raised that mitral regurgitation could have been underestimated in previous TEE due to reduced afterload caused by the hypotensive effect of sedation. It was then decided to repeat TEE, and, in order to counterpose the hypotensive effect of Midazolam, TEE was performed under intravenous continuous infusion of Phenylephrine, a selective α-1 receptor antagonist with a significant vasopressor effect and minimal effect on cardiac contractility. Systolic systemic arterial blood pressure during this exam was recorded as 135-140mmHg. In this exam mitral regurgitation was confirmed as severe and patient was patient was oriented for mitral valve surgery.
DIscussion
This case illustrates the importance of assessment of hemodynamic status of the patient during echocardiographic evaluation of mitral regurgitation severity, and presents a pharmacological strategy to compensate hypotensive effects of sedative agents used during TEE.

Abstract
Abstract
A 42-year old man with no relevant past medical history presented to the emergency department for recurrent transient loss of consciousness in the last 12 hours. 3 weeks earlier he had flu-like symptoms which spontaneously resolved.
Physical examination revealed altered mental state, heart rate 30 beats per minute, respiratory rate 30 cycles per minute, blood pressure 70/40mmHg and basal lung rales on pulmonary auscultation. Blood gas analysis revealed hyperlactacidemia with hypocapnia.
Electrocardiogram showed third-degree atrioventricular block. Atropine was administrated (total dose 3mg) with no rate response. Transcutaneous pacing was initiated followed by a temporary transvenous pacemaker, removed after 72 hours.
Transthoracic echocardiogram revealed compromised left ventricular systolic function (ejection fraction by Simpson’s method 45%) due to septal dyskinesia and reduced global longitudinal strain (-11%).
Blood analysis revealed erythrocyte sedimentation rate 20mm/hr, C-reactive protein 2.43mg/dL and negative high-sensitivity troponin T (9.44ng/L). Rheumatologic screening was negative. Coronary computed tomography angiography revealed normal epicardial coronaries.
Cardiac magnetic resonance imaging (CMRI) performed 7 days after admission revealed preserved left ventricular systolic function (ejection fraction 51%). Late gadolinium enhancement showed scared myocardium in the medium and basal segments of the interventricular septum, compatible with subacute myocarditis.
Due to the history of recurrent syncope, a permanent pacemaker was inserted. The patient was discharged the day after. No further syncope occurred. In last pacemaker follow-up, 9 months after presentation, patient had 0% auricular and ventricular pacing and 100% sensing over the previous 6 months.
Discussion
Transient atrioventricular block is a well-known complication of myocarditis when there is involvement of the conduction system by the inflammatory reaction. However, in rare cases it can persist or recur. CMRI plays an important role in these cases. Gadolinium-enhanced CMRI can be used to access the extent of inflammation and cellular edema and delayed-enhanced CMRI can also be used to quantify scarring which has important prognostic value. CMRI can also play a crucial role in excluding infiltrative disorders with conduction system involvement. Also, in these patients, the transient aspect of atrioventricular block poses a challenge when deciding about permanent pacemaker insertion.

Abstract
Abstract
Introduction
According to current guidelines, given a patient with low-gradient (aortic valve maximum velocity < 4m/s and/or aortic valve mean gradient <40mmHg), aortic valve area (AVA) < 1cm2 and low-flow (stroke volume (SV) < 35mL/min/m2), with preserved left ventricle function (ejection fraction (EF) ≥50%), an integrated approach for assessment of aortic stenosis severity is proposed. We aimed to investigate whether mitral regurgitation can play a role in those cases, possibly being responsible for low antegrade systolic flow.
Methods
We retrospectively analysed 121 consecutive transthoracic echocardiograms (TTEs) of patients with severe aortic stenosis, with AVA < 1.0cm2 as assessed by continuity equation. Patients with low ejection fraction (< 50%) were excluded. We therefore included 84 patients (females 53,6%, mean age 79,1+-10 years). Stroke volume was assessed by Doppler at the left ventricle outflow tract (LVOT). We then compared the prevalence of more than mild mitral regurgitation among patients with low-gradient and low-flow and the other patients.
Results
15 patients had both low-gradient, low-flow and preserved ejection fraction. There was a significant association regarding the presence of more than mild mitral regurgitation among these patients (p = 0.028, OR = 4.7, CI 95% 1.1-20.1). In these patients, it was also observed a higher prevalence of atrial fibrillation (p = 0.03, OR = 6.9, CI 95% 1.74-27.1), lower longitudinal systolic function of right ventricle as measured by TAPSE (16.6 vs 21.5mm, p = 0.028), and a tendency towards higher left atrial volume (113 vs 87mL, p = 0.06).
Conclusions
Given the findings that the prevalence of more than mild mitral regurgitation is higher in patients with severe aortic stenosis as assessed by AVA with both low-gradient, low-flow and preserved ejection fraction, we suggest that the presence of more than mild mitral regurgitation should be considered on the approach of aortic stenosis classification of these patients.

He had relevant personal medical history of mechanical aortic valve implantation 6 years before, coronary arterial disease with bypass graft surgery, chronic kidney disease on haemodialysis (with a need to implantation of long-duration haemodialysis catheter due to arteriovenous fistula thrombosis), Diabetes mellitus type 2 for 20 years, peripheral artery disease and ischemic stroke 2 years before.
He presented with a medical history of fever without evident clinical origin. From the diagnostic workup there were 4 blood cultures positive for methicillin-resistant Staphylococcus epidermidis. The bacteraemia was considered to be originated from the haemodialysis catheter and a new one was implanted. Transthoracic echocardiogram (TTE) at admission showed aortic anterior annulus dissection with an extensive dehiscence area (figure top-left). Subsequent evaluations showed fistulisation of the pseudoaneurysm to the right ventricle outflow tract (RVOT) (figure top-right and bottom-left) and the pulmonary trunk (PT) (figure bottom-right), as well as images compatible with vegetations at the septal cuspid of the pulmonary valve (figure yellow arrow). Furthermore, there was compromised right ventricle longitudinal systolic function and moderate tricuspid regurgitation with an estimated systolic pulmonary artery pressure of 80mmHg. Left ventricle systolic function was preserved and prothesis had no obstruction.
Case was discussed with cardiothoracic surgery from 2 centres and both considered that the surgical risk was too high. Patient was treated in a conservative way with rifampicin and gentamicin for 15 days and also with vancomycin ad eternum (after haemodialysis sessions). Blood cultures at discharge were negative. He remained hemodynamically stable and with no evidence of heart failure during admission.
Subsequent ambulatory clinical and echocardiographic monitoring was unremarkable in regarding to endocarditis, with no evidence of progression of endocarditis as well as no signs or symptoms of heart failure.
Patient died 10 months later due to sepsis originated on a lower limb infection of irreversibly ischemic tissue (patient had refused amputation before).
Discussion
Infective endocarditis of mechanical prosthesis has different presentations depending on the involvement of prosthesis and periprosthetic structures, and it is associated with high morbidity and mortality. Pseudoaneurysm of the intervalvular fibrosa is an uncommon complication, furthermore when complicating with dissection to near structures such as RVOT and the PT in this case. Treatment is mainly surgical, however, in this case the surgical risk was too high due to comorbidities and a conservative strategy was adopted. It seems that it was a reasonable strategy as the patient evolution was unremarkable when regarding endocarditis. Unfortunately, he ended up dying from probably unrelated complications.

Abstract
This study aims to obtain secondary metabolites extracts from filamentous fungi isolated from soil and marine sediments from Antarctic ecosystems and to assess its potential antibacterial activity on Xanthomonas euvesicatoria and Xanthomonas axonopodis pv. passiflorae (phytopathogenic bacteria causing diseases in pepper and tomato and passionfruit, respectively). Among the 66 crude intracellular and extracellular extracts obtained from fungi recovered from soil and 79 obtained from marine sediment samples, 25 showed the ability to prevent the growth of X. euvesicatoria in vitro and 28 showed the ability to prevent the growth of X. axonopodis pv. passiflorae in vitro. Intracellular and extracellular extracts from soil fungi inhibited around 97% of X. euvesicatoria and 98% of X. axonopodis pv. passiflorae at 2·1 mg ml-1 . The average inhibition rates against X. euvesicatoria and X. axonopodis pv. passiflorae for intracellular and extracellular extracts from marine sediments fungi were around 96 and 97%, respectively, at 3·0 mg ml-1 . Extracts containing secondary metabolites with antimicrobial activity against X. euvesicatoria and X. axonopodis pv. passiflorae were obtained, containing possible substitutes for the products currently used to control these phytopathogens. SIGNIFICANCE AND IMPACT OF THE STUDY Micro-organisms from extreme ecosystems, such as the Antarctic ecosystem, need to survive in harsh conditions with low temperatures, low nutrients and high UV radiation. Micro-organisms adapt to these conditions evolving diverse biochemical and physiological adaptations essential for survival. All this makes these micro-organisms a rich source of novel natural products based on unique chemical scaffolds. Discovering novel bioactive compounds is essential because of the rise in antibiotic-resistant micro-organisms and the emergence of new infections. Fungi from Antarctic environments have been proven to produce bioactive secondary metabolites against various micro-organisms, but few studies have shown activity against Xanthomonas phytopathogens.

Abstract
The aim of this work was to study the effect of different configurations of packaging on the volatile composition and sensory properties of a white wine. Certain oenological parameters were also evaluated. Bag-in-box (BIB) and glass bottles sealed with two different cork stoppers, natural and Neutrocork (technical), were used in the experiments. Analysis were carried out before packaging and after 3, 6 and 12 months of storage. Results showed that wines packaged in BIB presented higher levels of brown color than wines in bottles sealed with corks. In all packaging configurations, the content of free SO2 decreased with storage time; however, BIB wines showed a lower content of free SO2 than bottle wines during 12 months. Moreover, wines under BIB presented a significant lower amount of 2-phenylethanol, 2-phenylethyl acetate, isoamyl acetate, ethyl butanoate, ethyl hexanoate, ethyl octanoate, linalool and β-damascenone than bottled wines.

Abstract
Research describing the epidemiology of antibiotic resistant microbes is vital to the proactive development of new antimicrobial agents. In the last years, CTX-M extended-spectrum β-lactamases (ESBLs) have emerged worldwide and have replaced classical TEM and SHV-type ESBLs in many countries. CTX-M-15 is currently the most frequent, with a pandemic distribution, and its rapid spread is facilitated by incorporation of resistance genes in mobile genetic elements. The ESBL is efficacious in Gram-negative bacteria and thus closely associated with nosocomial environments, often colonizing the intestines, particularly in older and dependent patients. Little is known about the CTX-M ESBLs among Klebsiella pneumonia in Adjara. Our paper describes the detected and characterized ESBLs among Klebsiella pneumonia isolates from patients in two different hospitals in Adjara.

Abstract
For stationary sequences X = {Xn}n≥1 we relate τ, the limiting mean number of exceedances of high levels un by X1,…,Xn, and ν, the limiting mean number of upcrossings of the same level, through the expression θ = (ν/τ)η, where θ is the extremal index of X and η is a new parameter here called the upcrossings index. The upcrossings index is a measure of the clustering of upcrossings of u by variables in X, and the above relation extends the known relation θ = ν/τ, which holds under the mild-oscillation local restriction D″(u) on X. We present a new family of local mixing conditions D̃(k)(u) under which we prove that (a) the intensity of the limiting point process of upcrossings and η can both be computed from the k-variate distributions of X; and (b) the cluster size distributions for the exceedances are asymptotically equivalent to those for the lengths of one run of exceedances or the lengths of several consecutive runs which are separated by at most k − 2 nonexceedances and, except for the last one, each contain at most k − 2 exceedances.

Abstract
Random fields on , with long-range weak dependence for each coordinate individually, usually present clustering of high values. For each one of the eight directions in , we formulate restriction conditions on local occurrence of two or more crossings of high levels. These smooth oscillation conditions enable computation of the extremal index as a clustering measure from the limiting mean number of crossings. In fact, only four directions must be inspected since for opposite directions we find the same local path crossing behaviour and the same limiting mean number of crossings. The general theory is illustrated with several 1-dependent nonstationary random fields.

Abstract
Heat waves, high light intensities and water deficit are becoming important threats in many important viticultural areas worldwide, so the implementation of efficient and cost-effective mitigation strategies is crucial for the production of premium wines while maintaining productivity. In this context, the foliar application of kaolin, a chemically inert mineral with excellent reflective properties, is being developed and experimented as a strategy to reduce the impact of heat and drought in Douro vineyards (Northern Portugal), already revealing promising results. In the present study we investigated if an improved antioxidant capacity is part of the beneficial effects of kaolin, by studying changes in the enzymatic and nonenzymatic antioxidant system in leaves and berries (cv Touriga Nacional). Results showed that mature grape berries contained higher amounts of total phenols (40%), flavonoids (24%), anthocyanins (32%) and vitamin C (12%) than fruits from control vines, and important changes were also measured in leaves. In parallel, kaolin application improved the antioxidant capacity in berries, which was correlated with the observed increased content in secondary metabolites. Kaolin application also regulated secondary metabolism at the transcriptional level through the increase in the transcript abundance of genes encoding phenylalanine ammonia lyase and chalcone synthase.

Abstract
BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is the second most common neoplasia after adult kidney transplantation (KT). METHODS We retrospectively analyzed 8 adult patients who underwent KT in our center, diagnosed with PTLD between 2001 and 2014. RESULTS Six patients were men. The median age at presentation was 43 years and the median time since transplantation was 7.3 years. Three patients had previously received anti-thymocyte globulin/OKT3, and all were taking calcineurin inhibitors (CNI) at diagnosis. The monomorphic type was the most common, with diffuse large B-cell lymphoma as the origin. The most frequent presentation was fever. Four in five patients had Epstein-Barr-related PTLD. All patients received various regimens of immunosuppression reduction (IR), with 4 converting CNI to mTOR inhibitor (imTOR). Subsequent treatment (when needed) was chemotherapy, radiotherapy, and surgery. The maximum follow-up time was 6.7 years, with a 50% mortality rate that occurred at a median time of 3.5 months (2 died with functioning kidney). All 4 patients who were in remission at the end of follow-up had CNI conversion to imTOR, and none lost the allograft. CONCLUSIONS Despite the small number of cases, our results confirm the high PTLD impact in overall and allograft survival. Our PTLD type distribution is in accord with the literature. First-line PTLD treatment is IR, but the best method is still unknown; our results may suggest a beneficial effect of CNI conversion to imTOR.
