Abstract
BACKGROUND Pollen allergy poses a significant health and economic burden in Europe. Disease patterns are relatively homogeneous within Central and Northern European countries. However, no study broadly assessed the features of seasonal allergic rhinitis (SAR) across different Southern European countries with a standardized approach. OBJECTIVE To describe sensitization profiles and clinical phenotypes of pollen allergic patients in nine Southern European cities with a uniform methodological approach. METHODS Within the @IT.2020 multicenter observational study, pediatric and adult patients suffering from SAR were recruited in nine urban study centers located in seven countries. Clinical questionnaires, skin prick tests (SPT) and specific IgE (sIgE) tests with a customized multiplex assay (Euroimmun Labordiagnostika, Lübeck, Germany) were performed. RESULTS Three hundred forty-eight children (mean age 13.1 years, SD: 2.4 years) and 467 adults (mean age 35.7 years SD: 10.0 years) with a predominantly moderate to severe, persistent phenotype of SAR were recruited. Grass pollen major allergenic molecules (Phl p 1 and/or Phl p 5) ranged among the top three sensitizers in all study centers. Sensitization profiles were very heterogeneous, considering that patients in Rome were highly poly-sensitized (sIgE to 3.8 major allergenic molecules per patient), while mono-sensitization was prominent and heterogeneous in other cities, such as Marseille (sIgE to Cup a 1: n = 55/80, 68.8%) and Messina (sIgE to Par j 2: n = 47/82, 57.3%). Co-sensitization to perennial allergens, as well as allergic comorbidities also broadly varied between study centers. CONCLUSIONS In Southern European countries, pollen allergy is heterogeneous in terms of sensitization profiles and clinical manifestations. Despite the complexity, a unique molecular, multiplex, and customized in-vitro IgE test detected relevant sensitization in all study centers. Nevertheless, this geographical diversity in pollen allergic patients imposes localized clinical guidelines and study protocols for clinical trials of SAR in this climatically complex region.

Abstract
In the last years, there has been an increasing interest in llamas, not only as part of a productive system, but mostly as companion animals. Most reports regarding clinical biochemistry and haematology include few llamas and details about their health status are not available. The present study aims to provide haematological and biochemical parameters for llamas of known health status. Twenty-three non-pregnant females and seven males that live in Buenos Aires, Argentina (34°36'S, 58°22'W, at sea level) were studied. Llamas were clinically healthy, in good nutritional status. Animals were kept at grass and were fed hay bale or pellets and water ad libitum. Blood samples were collected by jugular venipuncture in spring. Packed cell volume, leucocyte count, differential white cell count, platelets count, urea, creatinine, total proteins, albumin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, glucose, calcium and phosphate were assessed. No significant differences were observed between males and females, except for platelet count and calcium, which was greater in males (P˂0.01). Values obtained for the different parameters were similar to those previously reported, except for monocytes, alkaline phosphatase, glucose and calcium, that were lower and lymphocytes and platelets count, that were higher in this study. In conclusion, different ambient and methodological conditions might affect some parameters. The parameters hereby presented are representative of llama's population living at sea level in South America.

Abstract
The fungal pathogen Paracoccidioides lutzii causes systemic mycosis Paracoccidioidomycosis (PCM), which presents a broad distribution in Latin America. Upon infection, the fungus undergoes a morphological transition to yeast cells and provokes an inflammatory granulomatous reaction with a high number of neutrophils in the lungs. In this work, we employed proteomic analysis to investigate the in vitro response of the fungus to the interaction with human neutrophils. Proteomic profiling of P. lutzii yeast cells harvested at 2 and 4 h post interaction with human polymorphonuclear cells allowed the identification of 505 proteins differentially accumulated. The data indicated that P. lutzii yeast cells underwent a shift in metabolism from glycolysis to Beta oxidation, increasing enzymes of the glyoxylate cycle and upregulating enzymes related to the detoxification of oxidative and heat shock stress. To our knowledge, this is the first study employing proteomic analysis in the investigation of the response of a member of the Paracoccidioides genus to the interaction with neutrophils.

Abstract
Aim: To access the metabolic changes caused by a chalcone derivative (LabMol-75) through a proteomic approach. Methods: Proteomic analysis was performed after 9 h of Paracoccidioides brasiliensis yeast (Pb18) cell incubation with the LabMol-75 at MIC. The proteomic findings were validated through in vitro and in silico assays. Results: Exposure to the compound led to the downregulation of proteins associated with glycolysis and gluconeogenesis, β-oxidation, the citrate cycle and the electron transport chain. Conclusion: LabMol-75 caused an energetic imbalance in the fungus metabolism and deep oxidative stress. Additionally, the in silico molecular docking approach pointed to this molecule as a putative competitive inhibitor of DHPS.

Abstract
Proteins rarely exert their function by themselves. Protein-protein interactions (PPIs) regulate virtually every biological process that takes place in a cell. Such interactions are targets for new therapeutic agents against all sorts of diseases, through the screening and design of a variety of inhibitors. Here we discuss several aspects of PPIs that contribute to prediction of protein function and drug discovery. As the high-throughput techniques continue to release biological data, targets for fungal therapeutics that rely on PPIs are being proposed worldwide. Computational approaches have reduced the time taken to develop new therapeutic approaches. The near future brings the possibility of developing new PPI and interaction network inhibitors and a revolution in the way we treat fungal diseases.

Abstract
PURPOSE Adolescents with cancer routinely report feelings of isolation and exclusion, including from medical decision-making. To address this problem and support adolescents, we designed and implemented the novel, virtual, weekly Teens4Teens peer support group and patient education program. We examined the views of participating adolescents, program guest speakers, and program moderators as they pertained to the need for the program, its feasibility, acceptability, and perceived impact. METHODS We recruited all available adolescents, moderators, and guest speakers who participated in Teens4Teens to take part in audio-recorded, semi-structured interviews. Interviews were transcribed, coded, and analyzed using thematic analysis. RESULTS We conducted 21 interviews across participant groups. We identified four broad themes: pathways into the Teen4Teens program, Teens4Teens implementation capacity, perspectives of the positive impact of Teens4Teens, and suggestions to improve Teens4Teens. These themes described a perceived need for adolescent-centered psychosocial programming in pediatric cancer care, provided lessons on how best to build and apply such a program, and highlighted the value of the program for both adolescents' and clinicians' acceptability, feasibility, and perceived utility. CONCLUSION Adolescents, guest speakers, and moderators valued Teens4Teens and made suggestions to improve capacity to routinely implement the program. Adolescent-tailored psychosocial programming, such as Teens4Teens, is positioned to be integrated into clinical care with relative ease and may serve to improve the cancer care experience of adolescents and their families. This study has potential to provide researchers and clinicians with valuable information about the content, design, and delivery of virtual peer support programming for adolescents with cancer.

Abstract
Aims: The development of safe and effective therapies for treating paracoccidioidomycosis using computational strategies were employed to discover anti-Paracoccidioides compounds. Materials & methods: We 1) collected, curated and integrated the largest library of compounds tested against Paracoccidioides spp.; 2) employed a similarity search to virtually screen the ChemBridge database and select nine compounds for experimental evaluation; 3) performed an experimental evaluation to determine the minimum inhibitory concentration and minimum fungicidal concentration as well as cytotoxicity; and 4) employed computational tools to identify potential targets for the most active compounds. Seven compounds presented activity against Paracoccidioides spp. Conclusion: These compounds are new hits with a predicted mechanisms of action, making them potentially attractive to develop new compounds.

Abstract
In fungal pathogens the cell wall plays an important role in host-pathogen interactions because its molecular components (e.g., polysaccharides and proteins) may trigger immune responses during infection. GPI-anchored proteins represent the main protein class in the fungal cell wall where they can perform several functions, such as cell wall remodeling and adhesion to host tissues. Genomic analysis has identified the complement of GPI-anchored proteins in many fungal pathogens, but the function has remained unknown for most of them. Here, we conducted an RNA expression analysis of GPI-anchored proteins of Paracoccidioides brasiliensis which causes paracoccidioidomycosis (PCM), an important human systemic mycosis endemic in Latin America. The expression of the GPI-anchored proteins was analyzed by quantitative PCR in both the mycelium and yeast forms. qPCR analysis revealed that the transcript levels of 22 of them were increased in hyphae and 10 in yeasts, respectively, while 14 did not show any significant difference in either form. Furthermore, we cloned 46 open reading frames and purified their corresponding GPI-anchored proteins in the budding yeast. Immunoblot and ELISA analysis of four purified GPI-anchored proteins revealed immune reactivity of these proteins against sera obtained from PCM patients. The information obtained in this study provides valuable information about the expression of many GPI-anchored proteins of unknown function. In addition, based on our immune analysis, some GPI-anchored proteins are expressed during infection and therefore, they might serve as good candidates for the development of new diagnostic methods.

Abstract
BACKGROUND The treatment of paracoccidioidomycosis (PCM) is a challenge, and the discovery of new antifungal compounds is crucial. The phenacylideneoxindoles exhibited promising antifungal activity against Paracoccidioides spp., but their mode of action remains unknown. METHODS Through proteomic analysis, we investigated the effects of (E)-3-(2-oxo-2-phenylethylidene)indolin-2-one on P. brasiliensis. In addition, we investigated the metabolic alterations of P. brasiliensis in response to the compound. Furthermore, the effects of the compound on the membrane, ethanol production, and reactive oxygen species (ROS) production were verified. RESULTS We identified differentially regulated proteins that revealed significant metabolic reorganization, including an increase in ethanol production, suggesting the activation of alcoholic fermentation and alterations in the rigidity of fungal cell membrane with an increase of the ergosterol content and formation of ROS. CONCLUSIONS These findings enhance our understanding of the mode of action and response of P. brasiliensis to the investigated promising antifungal compound, emphasizing its potential as a candidate for the treatment of PCM.

Abstract
(1) Background: Persons with chronic kidney disease may have sarcopenia characterized by the loss of muscle mass and loss of muscle strength. However, EWGSOP2 criteria to diagnose sarcopenia are technically challenging, especially in elderly persons on hemodialysis. Sarcopenia may be associated with malnutrition. We aimed at defining a sarcopenia index derived from malnutrition parameters for use in elderly haemodialysis patients. (2) Methods: A retrospective study of 60 patients aged 75 to 95 years treated with chronic hemodialysis was conducted. Anthropometric and analytical variables, EWGSOP2 sarcopenia criteria and other nutrition-related variables were collected. Binomial logistic regressions were used to define the combination of anthropometric and nutritional parameters that best predict moderate or severe sarcopenia according to EWGSOP2, and performance for moderate and severe sarcopenia was assessed by the area under the curve (AUC) of receiver operating characteristic (ROC) curves. (3) Results: The combination of loss of strength, loss of muscle mass and low physical performance correlated with malnutrition. We developed regression-equation-related nutrition criteria that predicted moderate sarcopenia (elderly hemodialysis sarcopenia index-moderate, EHSI-M) and severe sarcopenia (EHSI-S) diagnosed according to EWGSOP2 with an AUC of 0.80 and 0.866, respectively. (4) Conclusions: There is a close relationship between nutrition and sarcopenia. The EHSI may identify EWGSOP2-diagnosed sarcopenia from easily accessible anthropometric and nutritional parameters.

Abstract
Paracoccidioidomycosis (PCM) is a fungal disease caused by organisms of the genus Paracoccidioides spp. The treatment of the disease is lengthy and includes several adverse effects. Various methodologies focus on the search for new treatments against fungal disease, including the repositioning of drugs. Our group showed the fungicidal effect of mebendazole in P. brasiliensis cells. Thus, understanding the effect of exposing fungal cells to mebendazole is significant for further studies in order to demonstrate it as a potential drug for the treatment of PCM. A proteomic analysis of P. brasiliensis exposed to mebendazole was carried out. Analyses showed that exposure strongly affected the pathways related to energy production, such as glycolysis, fermentation, and the electron transport chain. The quantification of adenosine triphosphate (ATP) and mitochondrial activity demonstrated that the drug alters the electron chain, resulting in an increase in oxidative stress. Enzymes such as superoxide dismutase (SOD) and cytochrome c oxidase (Cyt C) were repressed in cells exposed to mebendazole. The concentration of ethanol produced by the cells under treatment demonstrated that the attempt to produce energy through fermentation is also arrested. Thus, the drug inhibits fungal growth through changes in energy metabolism, making it a promising compound for use in the treatment of PCM.

Abstract
Aims: Considering the need to identify new compounds with antifungal action, the activity of five 3-phenacylideneoxindoles compounds was evaluated. Materials & methods: The compounds were synthesized, and their antifungal activity was elucidated through minimum inhibitory concentration tests and interaction assay with other antifungals. Potential targets of compounds were predicted in silico. Results: 3-phenacylideneoxindoles compounds inhibited fungal growth with minimum inhibitory concentration and minimum fungicidal concentration ranging from 3.05 to 12.26 μM. The compounds demonstrated high selectivity index and presented a synergistic effect with itraconazole. In silico prediction revealed the pentafunctional AROM polypeptide, enolase, superoxide dismutase, catalase and kinases as proteins targets of the compound 4a. Conclusion: The results demonstrate that 3-phenacylideneoxindoles is a potential new class of antifungal compounds for paracoccidioidomycosis treatment.

Abstract
Background: Paracoccidioidomycosis is a neglected mycosis with a high socioeconomic impact that requires long-term treatment with antifungals that have limitations in their use. The development of antifungals targeting essential proteins that are present exclusively in the fungus points to a potentially promising treatment. Methods: The inhibitor of the enzyme homoserine dehydrogenase drove the synthesis of N'-(2-hydroxybenzylidene)-4-methoxy-1-naphthohydrazide (AOS). This compound was evaluated for its antifungal activity in different species of Paracoccidioides and the consequent alteration in the proteomic profile of Paracoccidioides brasiliensis. Results: The compound showed a minimal inhibitory concentration ranging from 0.75 to 6.9 μM with a fungicidal effect on Paracoccidioides spp. and high selectivity index. AOS differentially regulated proteins related to glycolysis, TCA, the glyoxylate cycle, the urea cycle and amino acid metabolism, including homoserine dehydrogenase. In addition, P. brasiliensis inhibited protein synthesis and stimulated reactive oxygen species in the presence of AOS. Conclusions: AOS is a promising antifungal agent for the treatment of PCM, targeting important metabolic processes of the fungus.

Abstract
Abstract
Aim
This study evaluates the versatility and performance of a novel adhesive for atraumatic hernia mesh fixation. The TISSIUM adhesive is a biodegradable and biocompatible viscous liquid that can be precisely applied to different tissue and mesh.1 Once in place, the surgeon utilizes a light probe to polymerize the adhesive, creating a flexible elastomeric connection that provides strong, durable and atraumatic mesh fixation.
Materials and Methods
The performance of the TISSIUM adhesive when used with a range of marketed mesh and against peritoneum (n=7) and muscle (n=3) was evaluated using a standardized lap-shear bench method using porcine tissues. The shear strength was compared to resorbable tacks (n=8) (against peritoneum as standard of care in IPOM) and self-adhesive meshes (n=4) and fibrin glue (n=3) (against muscle as classically used in the retromuscular approach).
Results
Lap-shear data revealed that the TISSIUM adhesive performance was equivalent to resorbable tacks when fixing meshes to the peritoneum. Similar testing protocol demonstrated that the TISSIUM adhesive shear strength was 6 to 13 times superior to non- penetrating fixation devices such as fibrin glue or self-adhesive mesh.
Conclusions
The use of the TISSIUM Adhesive for hernia mesh fixation is compatible with various mesh materials used in hernia repair and, in a bench model, outperforms existing non-penetrating methods in diverse tissue planes demonstrating the potential to help the surgeon achieve more effective and efficient atraumatic repair in a range of hernia procedures.

Abstract
Nitrogen is a crucial nutrient for microorganisms that compose essential biomolecules. However, hosts limit this nutrient as a strategy to counter infections, therefore, pathogens use adaptive mechanisms to uptake nitrogen from alternative sources. In fungi, nitrogen catabolite repression (NCR) activates transcription factors to acquire nitrogen from alternative sources when preferential sources are absent. Formamidase has been related to nitrogen depletion in Aspergillus nidulans through formamide degradation to use the released ammonia as a nitrogen source. In Paracoccidioides spp., formamidase is highly expressed in transcriptomic and proteomic analyses. Here, we aim to investigate the importance of formamidase to Paracoccidioides lutzii. Thereby, we developed a P. lutzii silenced strain of fmd gene (AsFmd) by antisense RNA technology using Agrobacterium tumefaciens-mediated transformation (ATMT). The AsFmd strain led to increased urease expression, an enzyme related to nitrogen assimilation in other fungi, suggesting that P. lutzii might explore urease as an alternative route for ammonia metabolism as a nitrogen source. Moreover, formamidase was important for fungal survival inside macrophages, as fungal recovery after macrophage infection was lower in AsFmd compared to wild-type (WT) strain. Our findings suggest potential alternatives of nitrogen acquisition regulation in P. lutzii, evidencing formamidase influence in fungal virulence.

Abstract
Germline pathogenic variants in BRCA1 and BRCA2 cause hereditary breast and ovarian cancer. The vast majority of these variants are inherited from a parent. De novo constitutional pathogenic variants are rare. Even fewer cases of constitutional mosaicism have been reported and these have mostly been described in women with breast cancer. Here we report low-level constitutional mosaicism identified by Next Generation Sequencing in two women with ovarian cancer. A BRCA1 c.5074G > A p.(Asp1692Asn) variant detected in the first female at 42 years, classed as likely pathogenic, was found in ~ 52% of reads in DNA extracted from tumour, ~ 10% of reads in DNA extracted from peripheral blood leukocytes and ~ 10% of reads in DNA extracted from buccal mucosa. The second BRCA1 c.2755_2758dupCCTG p.(Val920AlafsTer6) variant was detected in a female aged 53 years, classed as pathogenic, and was found in ~ 59% of reads in DNA extracted from tumour, ~ 14% of reads in DNA extracted from peripheral blood leukocytes and similarly in ~ 14% of reads in both DNA extracted from buccal mucosa and urine sample. Sanger sequencing confirmed the presence of these variants at a corresponding low level consistent with mosaicism that may not have been detected by this method alone. This report demonstrates the clinical benefit for two women of BRCA1/BRCA2 germline NGS testing at a depth that can detect low-level mosaicism. As well as informing appropriate treatments, tumour sequencing results may facilitate the detection and interpretation of low-level mosaic variants in the germline. Both results have implications for other cancer risks and for relatives when providing a family cancer risk assessment and reproductive risk. The implications for laboratory practice, clinical genetics management and genetic counselling for constitutional mosaicism of BRCA1/BRCA2 are discussed.

Abstract
Paracoccidioides spp. are the etiological agent of paracoccidioidomycosis, a disease that causes skin lesions and affect the lungs and other organs. The current management of the disease is long and has several side effects that often lead the patient to give up the treatment, sequelae and even death. The search for new forms of treatment that minimize these drawbacks is very important. Thus, natural compounds are targets of great interest. Curcumin is one of the main components of the tubers of Curcuma longa, presenting medicinal effects well described in the literature, including the antifungal effect on Paracocidioides brasiliensis. Nevertheless, the mechanisms related to the antifungal effect of such compound are still unknown, so the objective of the present research is to understand what changes occur in the metabolism of P. brasiliensis after exposure to curcumin and to identify the main targets of the compound. Proteomic analysis as based on nanoUPLC-MS analysis and the functional classification of the identified proteins. The main metabolic processes that were being regulated were biologically validated through assays such as fluorescence microscopy, EPR and phagocytosis. Proteomic analysis revealed that curcumin regulates several metabolic processes of the fungus, including important pathways for energy production, such as the glycolytic pathway, beta oxidation and the glyoxylate cycle. Protein synthesis was down-regulated in fungi exposed to curcumin. The electron transport chain and the tricarboxylic acid cycle were also down-regulated, indicating that both the mitochondrial membrane and the mitochondrial activity were compromised. Plasma membrane and cell wall structure were altered following exposure to the compound. The fungus' ability to survive the phagocytosis process by alveolar macrophages was reduced. Thus, curcumin interferes with several metabolic pathways in the fungus that causes paracoccidioidomycosis. BIOLOGICAL SIGNIFICANCE: The challenges presented by the current treatment of paracoccidioidomycosis often contributing to patients' withdrawal from treatment, leading to sequelae or even death. Thus, the search for new treatment options against this disease is growing. The discovery that curcumin is active against Paracoccidioides was previously reported by our study group. Here, we clarify how the compound acts on the fungus causing its growth inhibition and decreased viability. Understanding the mechanisms of action of curcumin on P. brasiliensis elucidates how we can seek new alternatives and which metabolic pathways and molecular targets we should focus on in this incessant search to bring the patient a treatment with fewer adverse effects.

Abstract
Electron paramagnetic resonance (EPR) spectroscopy of spin labels was used to characterize the interactions of amphotericin B (AmB), miltefosine (MIL) and nerolidol (NER) with the plasma membrane of Paracoccidioides brasiliensis. Spin-labeled analogs of stearic acid and steroid androstane distributed into the plasma membrane of the fungus treated with AmB, showed strong interactions with putative AmB/sterol complexes. The observed increase in the EPR parameter 2A// caused by AmB can be interpreted as a remarkable reduction in the spin label mobility and/or an increase in the local polarity. The 2A// parameter reduced gradually as the concentration of MIL and NER increased. The membrane-water partition coefficient (KM/W) of the three compounds under study was estimated based on the minimum concentration of the compounds that causes a change in EPR spectrum. The KM/W values indicated that the affinity of the compounds for the P. brasiliensis membrane follows the order: AmB > MIL > NER. The minimum inhibitory concentration (MIC) values were lower than the respective minimum concentrations of the compounds to cause a change in the EPR spectrum, being ∼3.5-fold lower for AmB, 3.9-fold for MIL and ∼1.4-fold for NER. Taken together, the EPR spectroscopy results suggest that the anti-proliferative effects of the three compounds studied are associated with alterations in cell membranes. One of the most likely consequences of these changes would be electrolyte leakage.Communicated by Ramaswamy H. Sarma.

Abstract
Abstract
Study question
Are the embryological, clinical and newborn outcomes using aspirated testicular sperm improved in cases with recurrent implantation failure previously treated with ejaculated sperm?
Summary answer
Aspirated testicular sperm enabled to obtain significant higher embryological, clinical and newborn outcomes in cases with recurrent implantation failure previously treated with ejaculated sperm.
What is known already
High levels of sperm DNA fragmentation (SDF) were associated to poor clinical outcomes (1-Simon et al., 2017). Testicular sperm display lower SDF than ejaculated sperm (2-Sakas and Alvarez, 2010), improving clinical outcomes in cases with abnormal semen parameters (3-Awaga et al., 2018; 4-Kang et al., 2018), recurrent implantation failure (RIF) and pregnancy loss (RPL) (5-Esteves et al., 2017), and elevated SDF (6-Ambar et al., 2021). As only a few studies are specifically dedicated to RIF, we expanded the number of cases and first provided full demographic, stimulation, embryological, clinical and newborn outcomes.

Study design, size, duration
We retrospectively evaluated during consecutive years (2010-2020) 63 patients with recurrent implantation failure, which accepted to perform testicular sperm aspiration (TESA) as an alternative treatment. These patients presented a long history of failed treatments (153 cycles) using ejaculated sperm. From these cycles, no pregnancy ensued. The present study compares 127 treatment cycles, 80 with testicular sperm (17 cases repeated TESA) and 47 with ejaculated sperm from the same patients performed at the present IVF clinic.
Participants/materials, setting, methods
Patients were screened for karyotype abnormalities, for Y-chromosome microdeletions (7-Gonçalves et al., 2016), and for SDF with the TUNEL assay (8-Sá et al., 2015). Conventional semen analysis was performed according to World Health Organization guidelines (9-WHO, 2010). Male evaluation and TESA was performed by the same experienced urologist (LF) according to established protocols (10-Madureira et al 2014). The procedure was performed entirely on an outpatient basis, with no complications reported.

Main results and the role of chance
The mean ages were 35.5±3.4 (26-42)-female and 38.1±5.7 (29-59)-male. There were 4 abnormal karyotypes (3-female, 1-male), all without known relevance. Most cases had asthenozoospermia and teratozoospermia (65.1%), or oligoasthenoteratozoospermia (41.8%). Of the 19 cases with <5M/ml, none presented Y-chromosome microdeletions. Although we do not routinely perform SDF testing, 15 patients had previous SDF values (12, >20%; 8, >36%). Female basal characteristics and testicular evaluation were under normal values. The TESA procedure took about 15-20 min, and the time of laboratorial search around 30-60 min. Cases using testicular sperm showed significant higher rates of fertilization (64% vs 73%-p=0.005), blastocyst development (47% vs 62%-p=0.010), implantation (6% vs 27%-p=0.000), clinical pregnancy (10% vs 39%-p=0.001), live birth delivery (5% vs 28%-p=0.005) and newborn (5% vs 32%-p=0.000) than ejaculated sperm. No significant differences were observed regarding the rates of embryo cleavage (95% vs 94.8%) and high quality embryos (89.4% vs 94%), in the mean number of transferred embryos (1.8±0.4 vs 1.9±0.4), or in the abortion rate (2 cases-50% vs 7 cases-25.9%). Cases using testicular sperm had 22 frozen-thawed embryo transfer cycles, enabling per initiated cycle a cumulative pregnancy rate of 45%, live birth delivery rate of 31.3% and newborn rate of 37.5% (32 newborn).
Limitations, reasons for caution
Although presenting the higher number of cycles using TESA in the treatment of RIF, this number needs to be increased for drawing more definitive conclusions, as these women present a diversity of conditions, rendering subgrouping difficult. In the future, it would also be important to evaluate SDF in all cases.
Wider implications of the findings
In conclusion, the present results gave further evidence for the superiority of using testicular sperm instead of ejaculated sperm in cases with recurrent implantation failure. Data also evidences the security of using testicular sperm aspiration, as there were no pregnancy or delivery complications, or congenital anomalies among the 32 newborn.

Abstract
Fungi of the Paracoccidioides genus are the etiological agents of the systemic mycosis paracoccidioidomycosis and, when in the host, they find a challenging environment that is scarce in nutrients and micronutrients, such as Fe, which is indispensable for the survival of the pathogen. Previous studies have shown that fungi of this genus, in response to Fe deprivation, are able to synthesize and capture siderophores (Fe3+ chelators), use Fe-containing host proteins as a source of the metal, and use a non-canonical reductive pathway for Fe3+ assimilation. Despite all of these findings, there are still gaps that need to be filled in the pathogen response to metal deprivation. To contribute to the knowledge related to this subject, we obtained the exoproteome of Paracoccidioides brasiliensis (Pb18) undergoing Fe deprivation and by nanoUPLC-MSE. One hundred forty-one proteins were identified, and out of these, 64 proteins were predicted to be secreted. We also identified the regulation of several virulence factors. Among the results, we highlight Cyb5 as a secreted molecule of Paracoccidioides in the exoproteome obtained during Fe deprivation. Cyb5 is described as necessary for the Fe deprivation response of Saccharomyces cerevisiae and Aspergillus fumigatus. Experimental data and molecular modeling indicated that Cyb5 can bind to Fe ions in vitro, suggesting that it can be relevant in the arsenal of molecules related to iron homeostasis in P. brasiliensis.

Abstract
BackgroundFiber-poor diets are linked to a reduction in gut microbiota diversity and gut barrier integrity, which is thought to promote the susceptibility to chronic inflammatory disorders1,2. We have previously shown that dietary resistant starch (RS) improves lupus-like disease in a murine model of SLE3 through the modulation of microbiota composition. If similar dysbiotic microbial community structures exist in subsets of SLE patients and if a RS intervention may be efficacious in those patients remains unclear.ObjectivesTo test if the dietary RS content in SLE and SLE-related antiphospholipid syndrome (APS) affect gut microbial taxa associated with SLE in published cohorts to date.MethodsWe obtained stool and blood samples as well as diet history for up to 3 visits (0, 4 and 8 weeks) from 12 SLE (n=28) and 15 APS (n=44) patients as well as 20 controls (n=48) as previously published4-6. Microbiota composition was defined by 16S rRNA V4 region sequencing on the Illumina platform and correlated with dietary fiber content extracted from a diet questionnaire. We used the FDA reference list to determine dietary RS contents in patients` regular diets and defined RS quantities as being low if less than 2.5 g/day and as medium if 2.5 to 15 g/day. None of the patients achieved high RS greater than 15 g/day. Mann-Whitney or Kruskal-Wallis tests were performed to compare bacteria relative abundances among the different groups. Simple linear regression was performed to relate the bacterial abundance to RS content and other metadata.ResultsMedium intake of RS was associated with beneficial Bifidobacterium spp. in SLE patients (p=0.016) but not APS (p=0.509). Instead, APS patients who consumed medium quantities of RS in their diets had less gut bacterial taxa that are capable of producing cardiolipins (among them Collinsella; p=0.009) and Ruminococcus gnavus (p=0.0142), a species previously associated with lupus nephritis7. A recent Japanese metagenome-wide study8 associated Streptococcus spp. and related redox reaction genes with SLE, which may also affect oxidative processes in APS9. We therefore also explored Streptococcus levels in SLE and APS patients and found unexpectedly a significant reduction of streptococci in a subset of APS (p=0.004) but not SLE patients (p=0.451) in medium compared to low RS dietary content. Streptococcus abundance was correlated with both Collinsella (R2=0.3141; p=<0,0001) and Ruminococcus gnavus (R2=0.1687; p=<0,0056) in APS patients.ConclusionMedium compared to low RS quantities in the regular diets of SLE and APS patients were associated with unique alterations in gut microbial community structures. Bifidobacterium increased in SLE patients with diets containing medium RS whereas APS patients with medium RS carried less cardiolipin-synthesizing taxa and lupus-related pathobionts. In particular, Streptococcus species recently strongly associated with SLE and redox reactions in Japanese patients in a metagenome-wide study8, were significantly suppressed in APS patients on medium RS diets. This modulatory effect was not seen in SLE patients or control subjects consuming medium RS. Together, these findings support distinct dietary effects on autoimmune gut microbiomes depending on the disease state. They also suggest potential beneficial effects of increased RS content on gut microbiota in SLE and APS patients. Fully resolving gut microbial signatures and clinical characteristics in these patients may identify the ideal subset to benefit from an interventional pilot trial with RS.References[1] Thorburn et al., 2014, Immunity 19, 833-842[2] Ruff et al, 2020, Nat Rev Microbiol 18, 521-538[3] Zegarra-Ruiz et al., 2019, Cell Host Microbe 25, 113-127[4] Greiling et al., 2018, Science Transl Med 10, 1–15[5] Manfredo Vieira et al, 2018, Science 359, 1156-1161[6] Ruff et al., 2019, Cell Host Microbe 26, 1–14[7] Azzouz et al., 2019, Ann Rheum Dis 78, 947–956[8] Tomofuji et al., 2021, Ann Rheum Dis 80, 1575–1583[9] Giannakopoulos and Krilis, 2013, New Engl J Med 368, 1033-1044AcknowledgementsThe work was supported by grants from the National Institutes of Health (NIH) (R01AI118855, T32AI07019), Arthritis National Research Foundation, Arthritis Foundation, Lupus Research Alliance, and Maren Foundation.Disclosure of InterestsMárcia Pereira: None declared, Iryna Kulyk: None declared, Sylvio Redanz: None declared, William E Ruff: None declared, Teri M.

Abstract
A comparative study was conducted on the efficiency of mercury removal using bacterial nanocellulose (BNC) membranes obtained from the fermentation of the microorganism Komagataeibacter medellinensis, in contrast with its oxidized analog obtained by modifying the bacterial nanocellulose membranes via oxidation with 2,2,6,6-Tetramethylpiperidine-1-oxyl. Both types of membranes (modified and unmodified) were characterized to identify variations in the Physico-chemical parameters after modification. FTIR spectra confirmed the chemical modification of cellulose in all reaction conditions by the presence of a new characteristic band at ∼1730 cm−1, corresponding to the new carboxylic groups produced by the oxidative process, and the decline of the band at ∼1,650 cm−1, corresponding to the hydroxyl groups of the C6 carbon. While the XRD profiles indicated that the percentage of BNC crystallinity decreased and the SEM images showed that the nanoribbon network was interrupted as the amount of oxidizing agent increased. The kinetics of mercury removal from both types of membrane was evaluated by calculating the concentration of mercury at different times and establishing a mathematical model to describe the kinetics of this process. The modified membranes improved significantly the adsorption process of the metal ion and it was found that the modification that results in the greatest adsorption efficiency was BNC-m 7.5 with a value of 92.97%. The results obtained suggest that the modification of the bacterial nanocellulose membranes by oxidation transcendentally improves the mercury removal capacity, outlining the modified membranes as an excellent material for mercury removal in wastewater.

Abstract
BACKGROUND Study TR03 evaluated the safety and efficacy of nalbuphine ER for prurigo nodularis (PN) (NCT02174419). OBJECTIVE We conducted supplementary analyses to assess the psychometric properties of the Worst Itch Numeric Rating Scale (WI-NRS), the TR03 primary endpoint. METHODS Study TR03 was a double-blind, placebo-controlled, phase 2 trial in PN patients with documented scores ≥5 on the WI-NRS (0 [no itch]-10 [worst itch imaginable]) on ≥5 of 7 days before baseline. Using TR03 data, the WI-NRS's psychometric properties, including reliability, validity, and ability to detect change, were evaluated. A responder threshold was estimated to facilitate interpretation of WI-NRS score changes. RESULTS Among 62 treated patients, improvements in mean [SD] (median) WI-NRS scores were observed between baseline (8.2 [1.21] (8.1)) and Week 10 (5.8 [2.43] (6.0)). The WI-NRS had an intraclass correlation coefficient of 0.96 (95% confidence interval, 0.93-0.98) in 42 patients who had stable Itch verbal rating scale (VRS) scores from Week 9-10, supporting strong test-retest reliability. Construct validity was supported, with strong correlations at Week 10 with Average Itch NRS (r=0.87) and Itch VRS single-day/weekly mean scores (r=0.81/0.89) and moderate correlations with ItchyQoLTM total/domain scores (r=0.41-0.43). The WI-NRS discriminated between predefined severity subgroups based on the Itch VRS and detected changes in itching severity (effect-size estimate: -2.05; standardized response mean: -1.21). An anchor-based threshold based on a two-category improvement in the single-day Itch VRS suggests a responder threshold of ≥3.8 points (~40% improvement). CONCLUSIONS The WI-NRS demonstrates good measurement properties, supporting its use in evaluating treatment change in PN.

Abstract
Bovine bacillary hemoglobinuria (BBH) produced by Clostridium novyi type D, is an endemic, highly fatal disease of cattle in the temperate grassland region of eastern Uruguay. A previous study showed that in this region, BBH is not associated with Fasciola hepatica or any other known focal-ischemic liver injury, so the reasons for its high incidence remains undetermined. The objective of this study was to analyze data from 45 Fasciola hepatica-free BBH outbreaks (1999-2019) in order to find common animal, seasonal and/or geographical risk factors, which may explain the occurrence of the epizootics. Fisher's goodness-of-fit testing showed a significantly higher case proportion of adult cows (N = 368, 80.5%) and lower of calves (N =8, 1.8%), as compared to the expected proportions of the censused population in the study area and historical submissions computed from the laboratory database (Chi-Sq = 346.2 and 174.8, df = 7, P < 0.00). Time series decomposition showed a bi-seasonal pattern, with a larger peak in spring and early summer (October to January) and a smaller increase in autumn (March-May). The lowest seasonal indices were on mid-summer (February) and winter (June-September). A combination of spatial statistics was used to assess the different spatial features of the disease and consistency of the findings. Global spatial autocorrelation showed BBH was significantly clustered (Moran's I = 0.407, P < 0.001). Both smoothed Anselin's Local Indicator of Spatial Autocorrelation and Kulldorff's spatial scan Poisson and Bernoulli models, detected roughly the same high-risk areas in the southeastern part of the Merin Lagoon basin, with the most likely cluster centered in the large wetland biosphere reserve "Eastern Wetlands and Coastal Strip" (RR = 9.12, P < 0.001). Outbreaks were georeferenced (latitude, longitude) and thematic dot-mapping geovisualization in Google Earth™ showed that the results were robust and truly geographic in nature. Most outbreaks (40/45, 88.8%) occurred on wetlands areas and large river valleys, characterized by poorly drained and frequently flooded soils, indicating that moisture-laden soils are the natural habitat of C. novyi type D. Grasslands in these endemic areas support rapid fattening of cattle during spring-summer, and somewhat less in autumn, in almost exact correspondence with BBH peaks, suggesting a close causal association in high-risk areas. Risk is significantly higher in adult cows probably because the spore content in the liver is highest in this category. The altered lipid metabolism and lipotoxicity in the liver may be the precipitating factor for spore germination and epizootic occurrence.

Abstract
The search for new compounds with activity against Paracoccidioides, etiologic agents of Paracoccidioidomycosis (PCM), is extremely necessary due to the current scenario of the available therapeutic arsenal. Treatment is restricted to three classes of antifungals with side effects. Curcumin is a polyphenol with antifungal effects that is extracted from Curcuma longa. The present work aimed to evaluate the activity of curcumin in different species of Paracoccidioides and to evaluate the potential molecular targets of curcumin using computational strategies. In addition, interactions with classic antifungals used in the treatment of PCM were evaluated. Curcumin inhibits the growth of Paracoccidioides spp. exerting a fungicidal effect. The combination of curcumin with amphotericin B, co-trimoxazole, and itraconazole showed a synergistic or additive interaction. Molecular targets as superoxide dismutase, catalase, and isocitrate lyase were proposed based on in silico approaches. Curcumin affects the fungal plasma membrane and increases the production of reactive oxygen species. Therefore, curcumin is a good alternative for the treatment of PCM.

Abstract
BACKGROUND The use of geostatistical methods remains rare in health studies. In order to assess the usefulness of the geostatistical approach in epidemiology, we chose to apply these methods to the vaccination coverage rate (VCR) against human papillomavirus (HPV) in France. Indeed, HPV vaccine coverage remains low in France and geographical disparities are sizable. The objective of this study was to identify the socioecological factors that may explain these geographical variations. METHODS Sociological, economic and behavioral data for 2016 have been gathered (demographics and public health database, web and social networks) and were correlated with the HPV VCR vaccine coverage over the French territory. Homogeneous geographical areas defined by strong correlations for groups of variables were selected. In each homogeneous area, principal component analysis was performed and a geostatistical approach provided an estimate predicting vaccine coverage at a given scale. RESULTS HPV VCR spatial variations in France cannot be fully explained by a single model. In urban areas, a low rate of HPV VCR is preferentially associated with unfavorable socioeconomic factors (poverty, unemployment, immigration). In rural areas, HPV VCR is preferentially associated with sociocultural factors (socio-professional categories, education level, interest in alternative medicines the anti-vaccine movement). Two secondary geographical areas were defined: the Île-de-France region and 12 departments in northeastern France. In the Île-de-France region, the association with the economic factors one again appears as in urban areas in general. The northeasteran departments represent a particular case insofar as HPV VCR is relatively high, notwithstanding economic poverty indicators. CONCLUSION Geostatistical modeling successfully identifies new potential explanations for HPV VCR geographical disparities in France. These results could help to adapt or develop future vaccination programs in specific areas by taking into account the sociological, economic and behavioral characteristics of their populations.

Abstract
INTRODUCTION Digital Mammography (DM-2D) and more recently Digital Breast Tomosynthesis (DBT), are two of the most effective imaging modalities for breast cancer detection, often used in screening programmes. It may happen that exams using these two imaging modalities are inadvertently performed to pregnant women. The objective of this study is to assess the dose in the uterus due to DM-2D and DBT exams, according to two main irradiation scenarios: in the 1st scenario the exposure parameters were pre-selected directly by the imaging system, while in the 2nd scenario, the maximum exposure parameters were chosen. METHODS The mammography equipment used was a Siemens Mammomat Inspiration. A physical anthropomorphic phantom, PMMA plates (simulating a breast thickness of 6 cm) and thermoluminescent dosimeters (TLDs) were used to measure entrance air kerma values on the phantom's breast and abdomen in order to successively estimate the mean glandular dose (MGD) and the dose in the uterus. For the two irradiation scenarios chosen, two-breast imaging modalities were selected: 1) DBT in Cranio-Caudal (CC) view (with 28 kV and 160 mAs as exposure parameters), 2) DBT and DM in Medio Lateral-Oblique (MLO) and CC views (with 34 kV and 250 mAs as exposure parameters). RESULTS In the 1st scenario, the TLD measurements did not detect significant dose values in the abdomen whereas the MGD estimated using the D.R. Dance model was in close agreement with data available in the literature. In the 2nd scenario, there was no significant difference in MGD estimation between the different views, whereas the air kerma values in the abdomen (in DBT mode, CC and MLO) were 0.049 mGy and 0.004 mGy respectively. In CC DM-2D mode the abdomen air kerma value was 0.026 mGy, with no significant detected value in MLO view. CONCLUSIONS For the dose in the uterus, the obtained values seem to indicate that DM-2D and DBT examinations inadvertently performed during pregnancy do not pose a significant radiological risk, even considering the case of overexposure in both breasts. IMPLICATIONS FOR PRACTICE The accurate knowledge of the doses in DM-2D and DBT will contribute to raise the awareness among medical practitioners involved in breast imaging empowering them to provide accurate information about dose levels in the uterus, improving their radiation risk communication skills and consequently helping to reduce the anxiety of pregnant women undergoing this type of examinations.

Abstract
Paracoccidioidomycosis (PCM) is a systemic mycosis, endemic in Latin America, caused by fungi of the genus Paracoccidioides. The treatment of PCM is complex, requiring a long treatment period, which often results in serious side effects. The aim of this study was to screen for inhibitors of a specific target of the fungus that is absent in humans. Methylcitrate synthase (MCS) is a unique enzyme of microorganisms and is responsible for the synthesis of methylcitrate at the beginning of the propionate degradation pathway. This pathway is essential for several microorganisms, since the accumulation of propionyl-CoA can impair virulence and prevent the development of the pathogen. We performed the modeling and molecular dynamics of the structure of Paracoccidioides lutzii MCS (PlMCS) and performed a virtual screening on 89,415 compounds against the active site of the enzyme. The compounds were selected according to the affinity and efficiency criteria of in vitro tests. Six compounds were able to inhibit the enzymatic activity of recombinant PlMCS but only the compound ZINC08964784 showed fungistatic and fungicidal activity against Paracoccidioides spp. cells. The analysis of the interaction profile of this compound with PlMCS showed its effectiveness in terms of specificity and stability when compared to the substrate (propionyl-CoA) of the enzyme. In addition, this compound did not show cytotoxicity in mammalian cells, with an excellent selectivity index. Our results suggest that the compound ZINC08964784 may become a promising alternative antifungal against Paracoccidioides spp. Communicated by Ramaswamy H. Sarma.

Abstract
Aim: To predict glycosylphosphatidylinositol (GPI)-anchored proteins in the genome of Paracoccidioides brasiliensis and Paracoccidioides lutzii. Materials & methods: Five different bioinformatics tools were used for predicting GPI-anchored proteins; we considered as GPI-anchored proteins those detected by at least two in silico analysis methods. We also performed the proteomic analysis of P. brasiliensis cell wall by mass spectrometry. Results: Hundred GPI-anchored proteins were predicted in P. brasiliensis and P. lutzii genomes. A series of 57 proteins were classified in functional categories and 43 conserved proteins were reported with unknown functions. Four proteins identified by in silico analyses were also identified in the cell wall proteome. Conclusion: The data obtained in this study are important resources for future research of GPI-anchored proteins in Paracoccidioides spp. to identify targets for new diagnostic tools, drugs and immunological tests.

Abstract
Summary Objective. To estimate the prevalence of self-reported adverse reactions (AdR) to subcutaneous airborne allergen immunotherapy (SCIT) and to describe factors associated with its occurrence. Methods. Real-life, observational, descriptive study of all patients treated with SCIT at a Portuguese allergy unit between 03/2017 and 06/2019, and who answered ≥1 time to a pre-SCIT evaluation questionnaire assessing the occurrence of local and/or systemic AdR in the previous administration. Results. 939 questionnaires from 231 patients (42% female, 35% with asthma) were included. Most (60%) SCIT preparations had multiple allergens with concentration adjusted to prevent dilution (MA-NoDil), 26% were single allergen with standard concentration (SA-SC), 10% single allergen with higher than standard concentration (SA-HC), and 4% mixtures without concentration adjustment (MA-Dil). SCIT-related AdR were self-reported in 313 (33%) administrations, 97% at the injection site and 11% grade 1 systemic symptoms. In a multivariable model, being a female and having asthma were associated with higher risk of AdR. MA-NoDil SCIT presented a lower risk of AdR compared to SA-SC SCIT. Conclusions. SCIT-related AdR were self-reported in 1/3 of the administrations, most at the injection site. The risk of AdR was higher in females and in patients with asthma. The lower risk of adverse reactions observed in SCIT preparations with multiple allergens with no dilutional effect should be further explored in future, targeted studies.

Abstract
Introduction Perfectionism is a consistent risk factor for various psychopathological conditions, including psychological distress and eating disorders. Recently, we have shown, for the first time, that there is a relationship between perfectionism and generalized problematic internet use/GPIU (Sobral et al. 2020). Specifically, we found that the role of perfectionism in psychological disorder is partially mediated by GPIU. On the other hand, it has been suggested that the widespread use of digital media can lead to negative body image perception and abnormal eating attitudes and behaviors. Objectives To explore, for the first time, the relationship between perfectionism, GPIU and disordered eating behavior. Methods 475 university students (78.9% girls; mean age 20.22±1.695) answered the Portuguese validated versions of: Composite Multidimensional Perfectionism Scale, GPIU Scale and Eating Attitudes Test-25. SPSS and Hayes’ Process Macro (2020) were used. Results Bulimic Behaviours/BB significantly and moderately correlated with Perfectionist efforts (r=.263), Perfectionist concerns (r=.284) and GPIU (r=.25) (all p<.001). The mediation analyses revealed that GPIU is a partial mediator of the relationship between both perfectionism dimensions and BB. Conclusions The evidence that both negative and “positive” perfectionism dimensions are associated to eating pathology is in line with our previous research. The present study adds, for the first time, that one of the perfectionism pathways of influence on BB operates through UGPI. Assessment and intervention to diminish eating psychopathology should focus on perfectionism and compulsive traits which could be involved in both ED and GPIU and in their comorbidity. Disclosure No significant relationships.

Abstract
Southern South American Proteaceae thrive on young volcanic substrates, which are extremely low in plant-available phosphorus (P). Most Proteaceae exhibit a nutrient-acquisition strategy based on the release of carboxylates from specialized roots, named cluster roots (CR). Some Proteaceae colonize young volcanic substrates which has been related to CR functioning. However, physiological functioning of other Proteaceae on recent volcanic substrates is unknown. We conducted an experiment with seedlings of five Proteaceae (Gevuina avellana, Embothrium coccineum, Lomatia hirsuta, L. ferruginea, and L. dentata) grown in three volcanic materials. Two of them are substrates with very low nutrient concentrations, collected from the most recent deposits of the volcanoes Choshuenco and Calbuco (Chile). The other volcanic material corresponds to a developed soil that exhibits a high nutrient availability. We assessed morphological responses (i.e., height, biomass, and CR formation), seed and leaf macronutrient and micronutrient concentrations and carboxylates exuded by roots. The results show that G. avellana was less affected by nutrient availability of the volcanic substrate, probably because it had a greater nutrient content in its seeds and produced large CR exuding carboxylates that supported their initial growth. Embothrium coccineum exhibited greater total plant height and leaf P concentration than Lomatia species. In general, in all species leaf macronutrient concentrations were reduced on nutrient-poor volcanic substrates, while leaf micronutrient concentrations were highly variable depending on species and volcanic material. We conclude that Proteaceae from temperate rainforests differ in their capacity to grow and acquire nutrients from young and nutrient-poor volcanic substrates. The greater seed nutrient content, low nutrient requirements (only for G. avellana) and ability to mobilize nutrients help explain why G. avellana and E. coccineum are better colonizers of recent volcanic substrates than Lomatia species.

Abstract
O treinamento físico regular faz parte do cotidiano militar, com intuito de aprimorar competências físicas essenciais para tarefas de combate. No entanto, quando executado de forma extenuante ou desenvolvido em condições climáticas adversas pode ocasionar o desenvolvimento da rabdomiólise por esforço físico. A rabdomiólise por esforço físico é definida como uma síndrome decorrente da necrose das células musculares, com sintomas variáveis, como dor muscular, fraqueza e aumento plasmático de enzimas musculares. A severidade da rabdomiólise por esforço físico varia individualmente, porém, pode se tornar clinicamente relevante, contribuindo para a hospitalização, insuficiência renal aguda, incapacidade permanente ou óbito. Sendo assim, o objetivo desta revisão narrativa é apresentar possíveis causas e fatores de risco para rabdomiólise, discutir sua fisiopatologia, seus possíveis diagnósticos e suas principais complicações, enfatizando o contexto militar.

Abstract
Paracoccidioidomycosis is a neglected disease that causes economic and social impacts, mainly affecting people of certain social segments, such as rural workers. The limitations of antifungals, such as toxicity, drug interactions, restricted routes of administration, and the reduced bioavailability in target tissues, have become evident in clinical settings. These factors, added to the fact that Paracoccidioidomycosis (PCM) therapy is a long process, lasting from months to years, emphasize the need for the research and development of new molecules. Researchers have concentrated efforts on the identification of new compounds using numerous tools and targeting important proteins from Paracoccidioides, with the emphasis on enzymatic pathways absent in humans. This review aims to discuss the aspects related to the identification of compounds, methodologies, and perspectives when proposing new antifungal agents against PCM.

Abstract
BRAF inhibitors revolutionised the management of melanoma patients and although resistance occurs, there is a subgroup of patients who maintain durable disease control. For those cases with durable complete response (CR) it is not clear whether it is safe to cease therapy. Here we identified 13 patients treated with BRAF +/- MEK inhibitors, who cease therapy after prolonged CR (median = 34 months, range 20-74). Recurrence was observed in 3/13 (23%) patients. In the remaining 10 patients with sustained CR off therapy, the median follow up after discontinuation was 19 months (range 8-36). We retrospectively measured ctDNA levels using droplet digital PCR (ddPCR) in longitudinal plasma samples. CtDNA levels were undetectable in 11/13 cases after cessation and remained undetectable in patients in CR (10/13). CtDNA eventually became detectable in 2/3 cases with disease recurrence, but remained undetectable in 1 patient with brain only progression. Our study suggests that consideration could be given to ceasing targeted therapy in the context of prolonged treatment, durable response and no evidence of residual disease as measured by ctDNA.

Abstract
Paracoccidioides is a genus of thermodimorphic fungi that causes paracoccidioidomycosis. When in the host, the fungus undergoes several challenges, including iron deprivation imposed by nutritional immunity. In response to the iron deprivation triggered by the host, the fungus responds in a ternary manner using mechanisms of high affinity and specificity for the uptake of Fe, namely non-classical reductive iron uptake pathway, uptake of host iron proteins, and biosynthesis and uptake of siderophores. This triple response resembles the rhythmic structure of a waltz, which features three beats per compass. Using this connotation, we have constructed this review summarizing relevant findings in this area of study and pointing out new discoveries and perspectives that may contribute to the expansion of this "little iron waltz".

Abstract
Abstract
Problem
The Salvador Municipal Health Secretariat (MHS) utilizes health data to elaborate technical documents to manage and respond to instances requiring internal or external control. In answer to demands for the modernization and transparency of municipal management, the constitution of a Health Situation Room (HSR) was included in the political agenda of the Secretary, thereby guaranteeing political, technical and operational support for its implementation.
Description of the Problem
To describe the process of construction of the HSR in the Salvador MHS in 2020. The HSR is a physical, virtual and collective space for the analysis of information, which begins with a data search which allows to understand the information flow, identifying the solicitor and the constructor of the information, the data source and the informational object itself.
Results
130 technicians and managers were interviewed, and their responses then categorized into 161 indicators across different themes. The results point out the need to define a spatial analysis unit to be adopted, and to communicate with external actors who demand information, as well as to develop a communication plan for the HSR.
Lessons
To develop an informational culture oriented by local and central protagonism, generating evidence for decision-making and information transparency for the whole of society.
Key messages
The Health Situation Room reduces the time between information-decision-action. The Health Situation Room prioritizes interdisciplinary collaboration and increases the efficiency of the health system.

Abstract
Oxygen is fundamental to the life of aerobic organisms and is not always available to Paracoccidioides cells. During the life cycle stages, reduced oxygen levels directly affect general metabolic processes and oxygen adaptation mechanisms may play a fundamental role on fungal ability to survive under such condition. Heme proteins can bind to oxygen and participate in important biological processes. Several fungi, including Paracoccidioides, express a heme-binding globin (fungoglobin - FglA) presumable to regulate fungal adaptation to hypoxia. However, the characterization of fungoglobin in Paracoccidioides spp. has not yet been performed. In this study, we predicted the structure of fungoglobin and determined its level of expression during hypoxic-mimetic conditions. Genomic screening revealed that the fungoglobin gene is conserved in all species of the Paracoccidioides genus. Molecular modeling showed biochemical and biophysical characteristics that support the hypothesis that FglA binds to the heme group and oxygen as well. The fungoglobin transcript and proteins are expressed at higher levels at the early treatment time, remaining elevated while oxygen is limited. A P. brasiliensis fglA knockdown strain depicted reduced growth in hypoxia indicating that this protein can be essential for growth at low oxygen. Biochemical analysis confirmed the binding of fungoglobin to heme. Initial analyzes were carried out to establish the relationship between FlglA and iron metabolism. The FglA transcript was up regulated in pulmonary infection, suggesting its potential role in the disease establishment. We believe that this study can contribute to the understanding of fungal biology and open new perspectives for scientific investigations.

Abstract
Copper is an essential micronutrient for the performance of important biochemical processes such as respiration detoxification, and uptake of metals like iron. Studies have shown that copper deprivation is a strategy used by the host against pathogenic fungi such as Cryptoccocus neoformans and Candida albicans during growth and development of infections in the lungs and kidneys. Although there are some studies, little is known about the impact of copper deprivation in members of the Paracoccidioides genus. Therefore, using isobaric tag labeling (iTRAQ)-Based proteomic approach and LC-MS/MS, we analyzed the impact of in vitro copper deprivation in the metabolism of Paracoccidioides brasiliensis. One hundred and sixty-four (164) differentially abundant proteins were identified when yeast cells were deprived of copper, which affected cellular respiration and detoxification processes. Changes in cellular metabolism such as increased beta oxidation and cell wall remodeling were described.
