Abstract
Abstract
Study question
Evaluate the influence of sperm selection according to the sorting technique, and its effects in clinical and laboratory parameters in IVF/PGT-A cycles.
Summary answer
Cycles that used microfluidic sperm selection device presented an increase in clinical pregnancy rates.
What is known already
A common genomic anomaly detected in subfertile men is the Sperm DNA fragmentation. It is resulted of a high concentation of free radicals produced causing oxidative stress in sperm cells. In order to achieve a normal embryonic development is necessary good spermatozoa with intact genetic material. In fact, embryonic quality parameters as lower fertilization, blastocyst formation and pregnancy rates has been related with Sperm DNA fragmentation increased cases. The microfluidic sperm selection device has been commercialized promising to select spermatozoa with a low level of DNA fragmentation and suggest a relationship between embryo quality, euploidy and pregnancy rates.
Study design, size, duration
A case-control study involving 494 IVF/PGT-A cycles that resulted in embryo biopsy between June, 2020 and November, 2021 at a Brazilian private practice unit (Instituto Ideia Fertil) were included in this analysis.
Participants/materials, setting, methods
All cycles that would perform PGT-A were splitted in two groups considering the sperm sorting technique: case - Microfluidic sperm selection device (245 cycles) and control - Density gradient centrifugation + swim-up (249 cycles) were included. The variables considered in this analysis were patient age, sperm concentration, fertilization, D3 top quality, blastocyst top quality, blastulation, ploidy and pregnancy rates. This data were analysed between groups and female age (until 37; 38-40 and over 41).
Main results and the role of chance
The mean age of the female and male patients found were 38.05 and 38.2 respectively and there was not statistically significant different between groups. Fertilization rate compared between case (72.4%) and control (76.5%) groups (p < 0.05) demonstrated statistically significant difference, but when stratified accordingly to the age, only the female age until 37 years old group showed significant difference (73.25%; 76.43%; p < 0.05). The variables analyzed as D3 Top Quality, Blastocyst Top Quality, blastulation and ploidy did not present difference (p = 0.552; 0.699; 0.378). The clinical pregnancy rate analyzed revealed in case group 65.33% and control 56.38% (p < 0.05), demonstrating statistically significant difference. When groups were splitted according to the female age (until 37 years old; 38-40 and over 41) the findings behaved in the same characteristics, increasing only the clinical pregnancy rate. The tests used was Mann-Whitney and Kruskal-wallis.
Limitations, reasons for caution
The DNA fragmentation test was not evaluated because not all patients had this test performed. Besides that, another parameter that will be analysed is live birth rate.
Wider implications of the findings
Microfluidic sperm sorting device made possible to select high quality spermatozoa according to motility, morphology, and low rates of fragmentation, showing the importance of having a good sperm in clinical pregnancy rate.

Abstract
AIM To describe standardised iterative methods used by a multidisciplinary group to develop evidence-based clinical intrapartum care algorithms for the management of uneventful and complicated labours. POPULATION Singleton, term pregnancies considered to be at low risk of developing complications at admission to the birthing facility. SETTING Health facilities in low- and middle-income countries. SEARCH STRATEGY Literature reviews were conducted to identify standardised methods for algorithm development and examples from other fields, and evidence and guidelines for intrapartum care. Searches for different algorithm topics were last updated between January and October 2020 and included a combination of terms such as 'labour', 'intrapartum', 'algorithms' and specific topic terms, using Cochrane Library and MEDLINE/PubMED, CINAHL, National Guidelines Clearinghouse and Google. CASE SCENARIOS Nine algorithm topics were identified for monitoring and management of uncomplicated labour and childbirth, identification and management of abnormalities of fetal heart rate, liquor, uterine contractions, labour progress, maternal pulse and blood pressure, temperature, urine and complicated third stage of labour. Each topic included between two and four case scenarios covering most common deviations, severity of related complications or critical clinical outcomes. CONCLUSIONS Intrapartum care algorithms provide a framework for monitoring women, and identifying and managing complications during labour and childbirth. These algorithms will support implementation of WHO recommendations and facilitate the development by stakeholders of evidence-based, up to date, paper-based or digital reminders and decision-support tools. The algorithms need to be field tested and may need to be adapted to specific contexts. TWEETABLE ABSTRACT Evidence-based intrapartum care clinical algorithms for a safe and positive childbirth experience.

Abstract
Abstract
Background
Malaria patients are at risk of cardiopulmonary complications, but diagnosis and management are difficult in resource limited environments. B-lines by lung ultrasonography (LUS) can identify pulmonary alterations, however, little is known about the usefulness in malaria.
Purpose
We aimed to investigate the occurrence of B-lines in acute malaria patients at baseline and at follow-up, and whether they are associated with shortness of breath and impaired left ventricular ejection fraction (LVEF).
Methods
Adult patients with non-severe acute malaria were prospectively enrolled from June to December 2020 in community healthcare clinics in a remote area. Patients were age- and sex-matched to controls without a prior history of malaria. We examined patients prior to anti-malaria treatment and at follow-up. Malaria treatment was administered according to national guidelines. Patients were excluded if they were pregnant, had concomitant infections or recent chest trauma. Patients underwent LUS (8-zones), echocardiography and peripheral blood smear. Measurements were blinded to clinical variables and outcomes.
Results
We included a total of 99 patients (median age 40±15 years, 55% men). Patients suffered from Plasmodium vivax (n=75), P. falciparum (n=22), and a mix of the two (n=2) and median parasite density was 1,595 parasites/mL (interquartile range [IQR] 528–6,585/mL). Follow-up was completed in 71 patients and the median follow-up time was 31 days (IQR 27–40 days).
Patients with acute malaria had significantly more B-lines at baseline than matched controls (P-value<0.001) and fewer B-lines at follow-up (P-value<0.001) (Figure 1). In acute malaria patients, number of B-lines at baseline correlated significantly with shortness of breath (OR 1.20, [1.04 to 1.39], P-value=0.01) and with LVEF (adjusted for age and sex: +8% [+1% to +15%], P-value=0.016 per 1% decrease in LVEF). There was no correlation between number of B-lines and parasite density (+2% [−5% to +11%], P-value=0.53 per 1000 increase in parasite density).
Conclusion
B-lines detected by LUS are more frequent in patients with acute malaria than in age- and sex-matched controls and decrease in response to treatment. B-lines also correlate with shortness of breath and lower LVEF at baseline. Because LUS is a quick and accessible examination, it may potentially facilitate risk stratification and therapeutic decisions regarding cardiopulmonary complications in patients with acute malaria.

Abstract
The current study aimed to identify differentially expressed genes and their biological process in the skeletal muscle of newborn goats as a function of maternal feed restriction during different stages of gestation. A total of 14 pregnant dams were randomly divided into one of the follow dietary treatments: Animals fed at 50% of maintenance requirement from 8-84 d of gestation and then fed at 100% of maintenance requirement from day 85 of gestation to parturition (RM, n = 6), and animals fed at 100% of maintenance requirement from 8-84 d of gestation and then fed at 50% of maintenance requirement from day 85 of gestation to parturition (MR, n = 8). At birth, all male offspring were euthanized and a sample of Logissimus muscle was collected for total RNA extraction and sequencing. Cuffdiff tool (Cufflinks 2.2.1) was used to count reads, normalize transcript expression (FPKM), and identify differentially expressed genes (DEG) between treatments. Network analysis was performed with String 11.0 using the available genome from the closest specie (Ovis aries). A total of 66 DEG (q-value < 0.05) were identified, with 6 up-regulated genes in skeletal muscle of RM compared to MR newborn goats. These genes are related to tissue development, such as CYTL1, UGT8, and NPNT. The 60 down-regulated genes in skeletal muscle of RM compared with MR newborn goats are related to transcription factors (TF) complex. Among the TF, FOS and JUNB families forms heterodimers in response to several stimuli (cytokines,growth factors, stress), and play key roles controlling a number of cellular processes, including signal transduction, cell proliferation, differentiation and apoptosis. In conclusion, maternal feed restriction at different stages of gestation affects tissue development and changes the transcription pattern in the skeletal muscle of newborn goats, which may lead to negative consequences in animal growth and performance.

Abstract
We aimed to investigate the impact of maternal feed restriction at different stages of gestation on proteomic profile in the skeletal muscle of newborn goats. A total of 14 pregnant dams were randomly divided into one of the follow dietary treatments: Animals fed at 50% of maintenance requirement from 8-84 d of gestation and then fed at 100% maintenance requirement from day 85 of gestation to parturition (RM, n = 6), and animals fed at 100% of maintenance requirement from 8-84 d of gestation and then fed at 50% maintenance requirement from day 85 of gestation to parturition (MR, n = 8). Longissimus muscle was sampled from male newborn goats and submitted to sarcoplasmic protein extraction and liquid chromatography coupled to mass spectrometry (LC-MS) analysis. The raw data were processed with MaxQuant (1.6.3.3) software with parameters set to default values. Label-free quantification (LFQ) was added and only protein ratios calculated from at least two unique peptides were considered. Our data showed 3 differentially expressed proteins down-regulated in RM (q-value < 0.05). Additionally, we observed proteins present exclusively in each treatment (RM= 137 proteins; MR= 41 proteins). The overall enriched pathways in RM newborn goats are associated with glycolysis (PKM), NADPH synthesis (PGD), lipid oxidation (ECHS1, ACAT1) and citrate cycle (ACO1, OGDH). While the overall enriched pathways in MR newborn goats are associated with glycolysis/gluconeogenesis (GAPDH, ENO) and citrate cycle (PDHA, IDH3A). In addition, correlation analysis between shotgun proteomics and RNAseq data from the same samples showed that there were no relationships between proteins and transcripts observed. These results indicate that maternal feed restriction during different stages of gestation alters enzymes and protein domains abundance associated with nucleotide metabolism in the skeletal muscle of newborn goats. Moreover, the lack of correlation between protein-transcript suggests the importance of post-transcriptional regulation of skeletal muscle metabolism as a consequence of maternal feed restriction at different stages of gestation.

Abstract
We assessed the effect of maternal feed restriction at different stages of gestation on growth and development of organs and small intestine of newborn goats. A total of 14 pregnant dams were randomly divided into one of the follow dietary treatments: Animals fed at 50% of maintenance requirement from 8-84 d of gestation and then fed at 100% maintenance requirement from day 85 of gestation to parturition (R-M, n = 6), and animals fed at 100% of maintenance requirement from 8-84 d of gestation and then fed at 50% maintenance requirement from day 85 of gestation to parturition (M-R, n = 8). At birth, newborns were slaughtered for collection of corporal components. No differences were observed among treatments for birth weight (P = 0.46). The weight of the complex reticulum-rumen-omasum tended to be heavier (P = 0.057) in the M-R group, when expressed per kg of body weight. The small intestine (P = 0.038) and total intestine (P = 0.038) were heavier in the offspring of the M-R group when expressed in kg of body weight. The M-R newborns had greater length of the small intestine (P = 0.043) and total intestine (P = 0.026). Maternal feed restriction did not influence the intestinal villi height (P = 0.406). However, newborn from R-M group had lower villus height:crypt depth ratio (P = 0.016), due to the tendency of the greater of crypt depth in these animals (P = 0.081). No differences among treatments were observed in mRNA expression of the MGAM and GLP-2R in the jejunum of the offspring (P > 0.12). Newborns of the M-R group tended to present greater mRNA abundance of the SLC5A1 (P = 0.091), SLC2A2 (P = 0.091), and OCLN (P = 0.061). In summary, restriction in the first half of gestation may be more detrimental to the performance and health of offspring throughout life due to increased impairment of intestinal development.

Abstract
Abstract
Family Health Support Centres (NASFs, in Portuguese) aim to develop interprofessional practices anchored in the assumptions of Primary Health Care, guided by the criteria of shared care specific professional interventions, management processes, interdisciplinarity, intersectoriality, Continuing Education in Health and health promotion. This health management methodology (Matrix Support) still represents a challenge to workers and managers, as it switches the logic of clinical thought from individual-centred, ambulatory and disciplinary care to collective, territory and interdisciplinary care. This study might illustrate and allow sharing of experiences about a work management format for multidisciplinary teams in Primary Health Care. A partnership between the University and the state health department was established in order to elaborate a collaborative, educational and supportive action. We formed a group of workers in the target area (24 municipalities and 18 teams) who had a focus on Continuing Education in Health using Institutional Analysis as theoretical reference. The main goal of the action was to provide spaces to share experiences and learning in the perspective of Continuing Education in Health. How does Continuing Education in Health support interprofessional practices in the field of Collective Health? Among the main results, we list: reflection about organisation practices of multiprofessional work, reflection about care practices and clinic management in the technical-assistance and pedagogic perspectives of Matrix Support; encouragement to improve the services offered in this level of care and their relationship with other points of the network. This experience showed us the importance of three main aspects: Continuing Education in Health, as a strategy of critical analysis about work and workers; the partnership and integration between teaching and service; and interprofessional formation processes (necessary to NASF and Collective Health).
Key messages
Continuing Education in Health is a strategy to deal with challenges and possibilities of interprofessional practices in the field of Collective Health. Enabling experiences and providing spaces for health professionals to share experience and learning.

Abstract
BACKGROUND Cardiac magnetic resonance (CMR) imaging has gained importance in pulmonary hypertension (PH) and studies have demonstrated its use as a surrogate marker and in following treatment of these patients. The pathophysiology of PH differs between pulmonary arterial hypertension (PAH, group 1) and chronic thromboembolic PH (CTEPH, group 4). OBJECTIVES The present study tested the hypothesis that PAH and CTEPH display different characteristics on CMR imaging. METHODS 46 patients were evaluated for pulmonary vascular disease in the French National Reference Center for PH (23 PAH and 23 CTEPH matched for age and gender). All patients had the right heart catheterization (RHC) and CMR imaging performed within 48h. CMR imaging was performed on a 1.5 T scanner. RESULTS PAH and CTEPH had similar body surface area and similar invasive hemodynamics, including mean pulmonary arterial pressure, cardiac index, pulmonary vascular resistance and right atrial pressure. PAH and CTEPH had similar CMR data. Right ventricular (RV) morphology and function and pulmonary artery (PA) data were also similar. CONCLUSION Age- and sex-matched PAH and CTEPH patients displayed similar values of the CMR indices of RV and PA morphology and function, suggesting that the RV-PA responses are similar in both groups, mostly related to the overall increase in after load.

Abstract
Abstract
Introduction: Marfan syndrome (OMIM #154700) was described for the first time in 1896 by Antoine Bernard-Jean Marfan. It is characterized by its autosomal dominant inheritance pattern, affects 1:5000 of those born alive, and involves the gene that codifies the structural protein fribrillin-1. Fibrillin-1 is critical for the formation of the elastic system backbone and for the negative regulation of the cytokine transforming growth factor beta 1 (TGF-β1). In the syndrome this fibrillar component causes the degeneration of the fibers of the elastic system, which no longer sequesters matrix TGF-β, causing disorganization of the collagen fibers and vascular smooth muscles. The disease affects mainly the cardiovascular system, cardiovascular problems being the main cause of death. This is because arteries have large amounts of elastic fibers that rupture in an adverse process, causing mainly dissections and aneurisms, which have been better clariied in experimental studies with mice. Objective: The objective of this study was to conduct an etiopathogenic and molecular review to describe the advances in the understanding of blood vessel dysmorphism in the syndrome, especially of the aorta. Materials and Methods: For this purpose the literature of the last 35 years was extensively reviewed. Conclusion: The origin of the aortic dysmorphism in the syndrome stems from a number of events that begin with the mutation of the gene fibrillin-1, causing fragmentation of the aortic elastic fibers. Excess cytokine TGF-β increases the amount of metalloproteinases and of vascular smooth muscle cell apoptosis, leading to matrix remodeling and increasing the susceptibility of the vessel to an aneurysm or dissecting process.

Abstract
Yttria-stabilized polycrystalline zirconia ceramics have greatly advanced over the past few years. High-translucent zirconia is a newly introduced ceramic that affords high strength and esthetics and that has significantly increased the clinical indications of monolithic zirconia restorations. Thus, the purpose of this case report was to evaluate the performance of ultrathin monolithic zirconia veneers adhesively luted to enamel surfaces after minimally invasive preparations; in addition, we aimed at presenting a clinical protocol for zirconia surface treatment in order to promote bonding effectiveness to resin cement. This type of restoration presented very acceptable esthetic results and decreased the risk of fracturing the veneer during try-in and clinical use. The results were still satisfactory after one-year follow-up. However, randomized, prospective, controlled clinical trials are required to determine the long-term clinical durability of this treatment.

Abstract
Abstract
Introduction: This study aimed to evaluate the simultaneous and maximum activities ofthe sternocleidomastoid (SCM) and pectoralis major (PM) muscles, to determine how the two types of breathing patterns (normal and forced) can affect these activities , and to verify which of these muscles could be used to establish an evaluation protocol for patients undergoing mechanical ventilation. Methods: Eleven healthy men, aged 18 to 25 years, participated in this study. The individuals remained in supine position using a respiratory belt to monitor both inspiratory and expiratory phase during shifts in the rib cage, performing three repetitions for the normal and forced respiratory movements, while keeping the breathing rhythm with a standard metronome. Electromyographic signals were captured using bipolar surface electrodes placed on the lower third of the SCM muscle and on the lower PM muscle fibers. Electromyographic signals were analyzed and the root mean square (RMS) values were calculated for a complete respiratory cycle. The EMG values were analyzed using the Bonferroni test for multiple comparisons. The homogeneity of variances was verified using the logarithmic transformation (LOG). The level of statistical significance was set at 5% (SPSS 19.0). Results: The values showed that there are signiicant differences between the EMG values of the SCM muscle during normal and forced respiration and the EMG values of the ECM and PM muscles during forced respiration. Conclusion: These results showed that the SCM muscle can be an indicator for the development of parameters to be used in the analysis of patients with respiratory failure.

Abstract
The order Chaetothyriales (Pezizomycotina, Ascomycetes) harbours obligatorily melanised fungi and includes numerous etiologic agents of chromoblastomycosis, phaeohyphomycosis and other diseases of vertebrate hosts. Diseases range from mild cutaneous to fatal cerebral or disseminated infections and affect humans and cold-blooded animals globally. In addition, Chaetothyriales comprise species with aquatic, rock-inhabiting, ant-associated, and mycoparasitic life-styles, as well as species that tolerate toxic compounds, suggesting a high degree of versatile extremotolerance. To understand their biology and divergent niche occupation, we sequenced and annotated a set of 23 genomes of main the human opportunists within the Chaetothyriales as well as related environmental species. Our analyses included fungi with diverse life-styles, namely opportunistic pathogens and closely related saprobes, to identify genomic adaptations related to pathogenesis. Furthermore, ecological preferences of Chaetothyriales were analysed, in conjuncture with the order-level phylogeny based on conserved ribosomal genes. General characteristics, phylogenomic relationships, transposable elements, sex-related genes, protein family evolution, genes related to protein degradation (MEROPS), carbohydrate-active enzymes (CAZymes), melanin synthesis and secondary metabolism were investigated and compared between species. Genome assemblies varied from 25.81 Mb (Capronia coronata) to 43.03 Mb (Cladophialophora immunda). The bantiana-clade contained the highest number of predicted genes (12 817 on average) as well as larger genomes. We found a low content of mobile elements, with DNA transposons from Tc1/Mariner superfamily being the most abundant across analysed species. Additionally, we identified a reduction of carbohydrate degrading enzymes, specifically many of the Glycosyl Hydrolase (GH) class, while most of the Pectin Lyase (PL) genes were lost in etiological agents of chromoblastomycosis and phaeohyphomycosis. An expansion was found in protein degrading peptidase enzyme families S12 (serine-type D-Ala-D-Ala carboxypeptidases) and M38 (isoaspartyl dipeptidases). Based on genomic information, a wide range of abilities of melanin biosynthesis was revealed; genes related to metabolically distinct DHN, DOPA and pyomelanin pathways were identified. The MAT (MAting Type) locus and other sex-related genes were recognized in all 23 black fungi. Members of the asexual genera Fonsecaea and Cladophialophora appear to be heterothallic with a single copy of either MAT-1-1 or MAT-1-2 in each individual. All Capronia species are homothallic as both MAT1-1 and MAT1-2 genes were found in each single genome. The genomic synteny of the MAT-locus flanking genes (SLA2-APN2-COX13) is not conserved in black fungi as is commonly observed in Eurotiomycetes, indicating a unique genomic context for MAT in those species. The heterokaryon (het) genes expansion associated with the low selective pressure at the MAT-locus suggests that a parasexual cycle may play an important role in generating diversity among those fungi.

Abstract
Avaliaram-se as características da carcaça de cabritos Saanen confinados, Saanen e 7/8 Boer - 1/8 Saanen semiconfinados, bem como a influência de grupo genético e sistema de terminação sobre o rendimento comercial, índice de compacidade, não constituintes, área de olho de lombo, força de cisalhamento, gordura, teor de umidade e teor de extrato etéreo. Utilizaram-se 31 machos inteiros, com aproximadamente 128 dias de idade e 22,9±2,4kg de peso vivo. Destes, 22 eram da raça Saanen e nove animais eram mestiços 7/8 Boer - 1/8 Saanen. Os animais da raça Saanen foram divididos em dois grupos de 11 animais, sendo um grupo mantido em confinamento e outro em semiconfinamento, enquanto os mestiços foram mantidos em semiconfinamento. Compararam-se os sistemas de terminação na raça Saanen, e os grupos genéticos no sistema semiconfinado. Os animais confinados receberam 3,5% do PV em ração completa peletizada; os semiconfinados tiveram acesso à pastagem e suplementação de 1,5% do PV em ração concentrada peletizada. Aos 47 dias de terminação, os animais foram abatidos e as características de carcaça determinadas por meio de uma amostra de lombo dissecado. Foram observadas diferenças entre sistemas de terminação para rendimento comercial de carcaça, índice de compacidade da carcaça, não constituintes de carcaça, área de olho de lombo, força de cisalhamento, gordura, teor de umidade e de extrato etéreo. Entre os grupos genéticos, foram observadas diferenças para área de olho de lombo, espessura de gordura e matéria mineral. O sistema de terminação exerceu influência sobre as características de carcaça avaliadas. A raça Saanen pode ser utilizada para a produção de carne quando submetida ao confinamento.

Barrett's esophagus (BE) is an intestinal metaplasia of the distal esophagus in which squamous cells are replaced by a columnar epithelium. It is considered as a premalignant lesion, which can lead to esophageal adenocarcinoma, a very aggressive type of cancer, and can often be found in patients with gastro-esophageal reflux disease (GERD). In spite of the widespread use of acid-suppressing therapy with proton pump inhibitors, the incidence of adenocarcinoma has been steadily rising during the last 30 years. So, it can strongly be suggested that refluxed material other than acid might contribute to the progression of cancer within Barrett's esophagus. Along with gastric acid, bile acids enter the esophagus during an episode of reflux, and bile acids may be important in carcinogenesis. In their refluxates, patients with GERD and BE show high concentrations of the hydrophobic bile salt deoxycholic acid (DCA), which has cytotoxic effects and is able to induce DNA damage in different cell types. Other bile acids, like the hydrophilic urodeoxycholic acid (UDCA), have been therapeutically used to treat cholestatic liver diseases and to prevent colon carcinoma. This article reviews the effects of bile acids and points out new perceptions in the progression of Barrett's-associated carcinogenesis.

Abstract
Five castrated and ruminally cannulated Saanen goats (±48.19kg) were used to evaluate intake, digestibility and rumen fermentation parameters of diets with inactive dry yeast as a soybean meal substitute (0, 25, 50, 75 and 100%). Goats were randomly assigned to a 5×5 (five levels of dry yeast x five periods) Latin square design. Diets were composed of corn silage (40%), ground corn, soybean meal and/or dry yeast and mineral supplement. The intake and digestibility of DM, OM, CP, NDF and TC were not influenced by the treatments. However, EE intake showed negative linear effect. The TDN content did not change with the inclusion of dry yeast in the diets. The pH, N-NH3 concentration and rumen short-chain fatty acids content did not differ among diets. Rumen content scanning electron microscopy observations did not suggest microbial colonization and degradation changes. Dry yeast from sugar cane can replace soybean meal in diets for Saanen goats without changing the rumen fermentation pattern, intake and digestibility.

Abstract
Rapid Ecological Assessment protocols are important tools for the training of postgraduate students, as well as the collection of data on poorly-known and protected areas with the potential for the preservation of water supplies for urban areas. The objective of this study was to perform a survey of water quality and diversity of benthic macroinvertebrates in two sub-basins at the Mata do Junco Wildlife Refuge in the Brazilian state of Sergipe. The collection of data in the field, laboratory processing, and the interpretation and discussion of data were conducted in groups by students from two postgraduate programmes in Ecology and Conservation (UFMG and UFS), personnel of the state environment agency (SEMARH), school teachers from the local town of Capela, and members of the reserve's voluntary fire brigade. The results of the assessment were organised, analysed, and presented at the reserve headquarters in the form of posters, for the development of environmental education activities with pupils from local schools, as well as contributing to a SEMARH seminar. Samples were characterised by distinct taxonomic compositions and diversity, as confirmed by MDS and additive partitioning of diversity analyses. The gravel substrate presented the lower mean taxonomic richness in each sampling unit (a1 = 28%), while the average difference among samples (b1 diversity) was elevated for both substrates (39% for leaf litter, 41% for gravel), reflecting the pronounced variation among samples, even adjacent ones within the same stream. Diversity between streams was lower in the case of leaf litter in comparison with gravel (b2 = 21 and 31%, respectively). A total of 57 fish specimens were collected with a predominance of individuals of the orders Characiformes (62%) and Perciformes (21%). This rapid ecological assessment confirmed the importance of the conservation unit and emphasised the need for its continuation, given its importance for the maintenance of water quality and its other ecological services, such as the conservation of the region's aquatic biodiversity and providing the local town of Capela (circa 20,000 inhabitants) with its water supply, the Mata do Junco being its only source.

Abstract
Recent studies have recognised the importance of pulmonary hypertension (PH) in sickle cell disease (SCD). The aim of this study was to determine the prevalence and prognostic impact of PH and its features in patients with SCD. 80 patients with SCD underwent baseline clinical evaluation, laboratory testing, 6-min walk tests (6MWTs) and echocardiography. Patients with a peak tricuspid regurgitant jet velocity (TRV) of ≥ 2.5 m·s(-1) were further evaluated through right heart catheterisation (RHC) to assure the diagnosis of PH. Our study evidenced a 40% prevalence of patients with elevated TRV at echocardiography. RHC (performed in 25 out of 32 patients) confirmed PH in 10% (95% CI 3.4-16.5%) of all patients, with a prevalence of post-capillary PH of 6.25% (95% CI 0.95-11.55%) and pre-capillary PH of 3.75% (95% CI -0.4-7.9%). Patients with PH were older, had worse performance in 6MWTs, and more pronounced anaemia, haemolysis and renal dysfunction. Survival was shorter in patients with PH. Our study reinforced the use of echocardiography as a screening tool for PH in SCD and the mandatory role of RHC for proper diagnosis. Our findings confirmed the prognostic significance of PH in SCD as its association to pronounced haemolytic profile.

Abstract
BACKGROUND Factors other than acid may play a role in gastro-oesophageal reflux disease (GERD) and its complications. AIM To assessed the role of bile acids in the pathogenesis of GERD, Barrett's oesophagus and Barrett's-related neoplasia. METHODS We conducted a systematic review of computerised bibliographic databases for original articles involving humans or human oesophageal tissue or cells that assessed exposure to or manipulation of bile acids. Outcomes assessed included GERD symptoms; gross oesophageal injury; Barrett's oesophagus and related neoplasia; and intermediate markers of inflammation, proliferation or neoplasia. RESULTS Eighty-three original articles were included. In in vivo studies, bile acids concentrations were higher in the oesophageal aspirates of patients with GERD than controls, and bile acids infusions triggered GERD symptoms, especially in high concentrations or in combination with acid. In ex vivo/in vitro studies, bile acids stimulated squamous oesophageal cells and Barrett's epithelial cells to produce inflammatory mediators (e.g., IL-8 and COX-2) and caused oxidative stress, DNA damage and apoptosis. They also induced squamous cells to change their gene expression pattern to resemble intestinal-type cells and caused Barrett's cells to increase expression of intestinal-type genes. CONCLUSIONS In aggregate, these studies suggest that bile acids may contribute to the pathogenesis of symptoms, oesophagitis and Barrett's metaplasia with related carcinogenesis in patients with GERD. However, all study results are not uniform and substantial differences in study parameters may explain at least some of this variation.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive, fatal disease. We studied 674 consecutive adult patients who were prospectively enrolled in the French PAH registry (121 incident and 553 prevalent cases). Two survival analyses were performed. First, the cohort of 674 patients was followed for 3 yrs after study entry and survival rates described. Then, we focused on the subset with incident idiopathic, familial and anorexigen-associated PAH (n = 56) combined with prevalent patients who were diagnosed <3 yrs prior to study entry (n = 134). In the cohort of 674 patients, 1-, 2-, and 3-yr survival rates were 87% (95% CI 84-90), 76% (95% CI 73-80), and 67% (95% CI 63-71), respectively. In prevalent idiopathic, familial and anorexigen-associated PAH, 1-, 2-, and 3-yr survival rates were higher than in incident patients (p = 0.037). In the combined cohort of patients with idiopathic, familial and anorexigen-associated PAH, multivariable analysis showed that survival could be estimated by means of a novel risk-prediction equation using patient sex, 6-min walk distance, and cardiac output at diagnosis. This study highlights survivor bias in prevalent cohorts of PAH patients. Survival of idiopathic, familial and anorexigen-associated PAH can be characterised by means of a novel risk-prediction equation using patients' characteristics at diagnosis.

Abstract
OBJECTIVE To determine the prevalence of and independent factors associated with joint involvement in a large population of patients with systemic sclerosis (SSc). METHODS This study was cross-sectional, based on data collected on patients included in the European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) registry. We queried this database to extract data regarding global evaluation of patients with SSc and the presence of any clinical articular involvement: synovitis (tender and swollen joints), tendon friction rubs (rubbing sensation detected as the tendon was moved), and joint contracture (stiffness of the joints that decreased their range of motion). Overall joint involvement was defined by the occurrence of synovitis and/or joint contracture and/or tendon friction rubs. RESULTS We recruited 7286 patients with SSc; their mean age was 56 +/- 14 years, disease duration 10 +/- 9 years, and 4210 (58%) had a limited cutaneous disease subset. Frequencies of synovitis, tendon friction rubs, and joint contractures were 16%, 11%, and 31%, respectively. Synovitis, tendon friction rubs, and joint contracture were more prevalent in patients with the diffuse cutaneous subset and were associated together and with severe vascular, muscular, renal, and interstitial lung involvement. Moreover, synovitis had the highest strength of association with elevated acute-phase reactants taken as the dependent variable. CONCLUSION Our results highlight the striking level of articular involvement in SSc, as evaluated by systematic examination in a large cohort of patients with SSc. Our data also show that synovitis, joint contracture, and tendon friction rubs are associated with a more severe disease and with systemic inflammation.
