Abstract
Study question
What is the clinical outcome of collapsed blastocysts without signals of re-expansion in frozen embryo transfers (FET)?
Summary answer
FET of non-re-expanded blastocysts after thawing showed a live-birth rate in 11.5% of the cases. Embryos vitrified on day 5 revealed the best results.
What is known already
Embryo viability is crucial for FET to be successful. Since the introduction of vitrification techniques, outcomes have improved substantially and are even comparable to fresh transfers. Nevertheless, some indicators may help predict the outcome of frozen-thawed blastocysts. Blastocoele re-expansion after thawing has been widely studied and is a strong predictor of clinical pregnancy outcome. However, accurate data on non-re-expanded blastocysts after FET is still not available. Hence, this study aims to evaluate the clinical outcome of non-re-expanded blastocyst after FET.
Study design, size, duration
The retrospective study was designed and conducted at the Kinderwunsch Institut Schenk GmbH (Dobl, Austria). Data was collected from FET performed between 2017 and 2021. In total, 104 FET cycles of collapsed blastocysts were analysed. All the transfers performed were single embryo transfers (SET). Patient’s average age was of 33.6 years at the time of embryo vitrification. Embryos were excluded if they showed more fragmentation than before vitrification.
Participants/materials, setting, methods
Patients were divided into two groups following the time of blastocyst cryopreservation: day 5 (44 SET) and day 6 (60 SET); which was dependant on the time of blastocoel expansion. They were further divided according to the trophectoderm quality: good (42 SET) and poor (62 SET) and the overall embryo quality, considering trophectoderm and inner cell mass (ICM): good (37 SET) and poor (67 SET). In both cases quality was assessed before vitrification.
Main results and the role of chance
A total of 104 collapsed blastocysts were transferred (SET). 16.3% of the patients had a positive biochemical pregnancy. 11.5% of the pregnancies resulted in a live birth and 4.8% of the pregnancies ended in abortion. FET with day 5 non-re-expanded blastocysts after thawing showed better results than day 6 thawed blastocysts regarding biochemical pregnancy (29.5% vs 6.6%, p = 0.02) and live birth rate (20.4% vs 5%, p = 0.017). Good embryo quality before vitrification showed a trend for better clinical outcome, however, results were not significant. A good trophectoderm quality before vitrification revealed a live birth rate of 16.7% compared to 8.1% in poor trophectoderm quality. Regarding overall embryo quality (trophectoderm and ICM quality) the results were 14.3% deliveries for good quality blastocysts vs 7.6% for poor quality blastocysts.
Limitations, reasons for caution
The sample size may be seen as a study limitation. However, statistically significant results were obtained. Nonetheless, results should be confirmed with a bigger sample size.
Wider implications of the findings
The present study revealed a lower chance of live birth for non-re-expanded blastocysts after thawing, which should nevertheless not be overlooked; specially in cases with good quality embryos frozen and thawed on day 5. Transfer of collapsed embryos after thawing would be recommended taking into consideration the study results.

Abstract
Abstract
Study question
Is there a difference in bacterial composition of follicular fluid between oocytes developing a good quality blastocyst and oocytes that fail fertilization?
Summary answer
Follicular fluids of oocytes failing fertilization show a different bacterial profile compared to follicular fluids of oocytes that were successfully fertilized.
What is known already
The presence of pathogens in the female reproductive tract has been intensively investigated. Lactobacillus species are mainly associated with a healthy genital tract and good prognosis for a successful pregnancy. Studies of the bacterial composition of follicular fluids have been mainly undertaken in women participating in reproductive medicine treatment because of the nature to obtain the specimen. In most studies follicular fluids have been pooled for analysis. Information on separately collected follicular fluids is still rare. We hypothesized that the composition of bacteria within follicular fluids is responsible for the success of the fertilization process.
Study design, size, duration
The study was designed and conducted at the Kinderwunsch Institut Schenk GmbH (Dobl, Austria) together with DNA-Technology. Follicular fluids from 46 patients undergoing IVF (in vitro fertilization) and ICSI (intracytoplasmic sperm injection) treatment were included and analyzed.
Participants/materials, setting, methods
Follicular fluids from 46 patients were collected separately. 2 follicular fluids from each patient were screened for common bacteria of the genital tract. One from an oocyte developing a good quality blastocyst and one displaying fertilization failures. Samples were analyzed for bacterial composition using the Femoflor16 (DNA-Technology).
Main results and the role of chance
Quantitative analysis revealed a higher total bacteria mass in follicles from oocytes that failed fertilization. Furthermore, Lactobacillus were not present in those follicles compared to good blastocyst follicles. In addition, Chlamydia trachomatis was found mainly in follicular fluid of not fertilized oocytes together with Eubacterium, Gardnarella and Trichomonas species. Interestingly, a trend of elevated levels of Ureaplasma species in follicular fluids of oocytes developing good quality blastocysts was observed.
Limitations, reasons for caution
Contamination of follicular fluids due to the procedure of oocyte pick up and follicular fluid retrieval cannot be completely excluded. Results should be confirmed with a higher sample size.
Wider implications of the findings: We assume that different bacterial compositions in follicular fluids are responsible for the destiny of the oocyte. It is tempting to speculate that bacterial analysis of follicular fluids may be beneficial to select to best oocytes in future IVF/ICSI treatments.

Abstract
Background:Janus kinases (JAKs) serve as signaling hubs orchestrating inflammation, innate and adaptive immunity and erythropoiesis. Unfortunately, some of these agents cause suppression of JAK-dependent erythropoiesis, thereby exacerbating inflammation-associated anemia, leading to potential under-dosing and reduced therapeutic benefit. We previously showed that the JAKi momelotinib (MMB) can correct anemia in a rat model of RA, an effect that has been clinically reproduced in myelofibrosis patients treated with MMB. Subsequently, the molecular basis for MMB’s anemia benefit was determined to be a consequence of its potent inhibition of Activin Receptor Type 1 (ACVR1), resulting in decreased hepcidin and, as a consequence, increased systemic iron availability and improved erythropoiesis.Objectives:The goal of the current study was to investigate the effects of MMB on arthritis in pre-clinical RA models.Methods:The anti-arthritic activity of daily administration of MMB was assessed in Streptococcus cell wall-induced arthritis in Lewis rats (PG-PS model) and in collagen antibody-induced arthritis (CAIA) in DBA/1 mice. Consecutive assessment of arthritis was performed by joint thickness measurements and paw scoring. Following 3 weeks of treatment, synovial immune cell infiltration and T cell subset differentiation was quantified. Cytokine gene expression was profiled by quantitative rt-PCR. Anemia was assessed by determination of blood hemoglobin and serum, spleen and liver iron levels.Results:MMB reduced inflammatory granulocyte and macrophage infiltration in synovial tissue by more than 60% at all tested doses as compared to vehicle treatment in PG-PS animals. Importantly, MMB treatment effectively decreased arthritogenic Th17 cell differentiation and overall CD4+ T cells in the synovia beginning at the lowest tested dose and coincided with complete remission of joint swelling at 25 mg/kg. Anti-arthritic activity of MMB was confirmed with significant reductions in arthritis scoring, which demonstrated non-inferiority versus the TNF-α inhibitor, etanercept, in the CAIA model. Consistent with its inhibitory activity on the ACVR1-hepcidin axis, MMB reduced circulating hepcidin levels and mobilized systemic iron, resulting in substantial improvement of the RA-associated anemia in rats.Conclusion:MMB is a highly efficacious anti-arthritic agent that ameliorates local joint inflammation and reduces the systemic differentiation of major arthritogenic effector cell population, Th17 lymphocytes. In accord with our previous report, MMB is distinct from other JAKi due to its ability to inhibit ACVR1 signaling leading to decreased plasma hepcidin, improved iron homeostasis and increased erythropoiesis. The dual anti-inflammatory and anemia-improving pharmacologic activities of MMB position it as a promising and differentiated therapeutic agent for the treatment of RA and other inflammatory diseases with an anemia component.Disclosure of Interests:Piotr Tymoszuk: None declared, Verena Petzer: None declared, Malte Asshoff: None declared, Andrea Schroll: None declared, Markus Seifert: None declared, Ryan Hansen Employee of: I’m a former employee of Sierra Oncology, Snezana Milutinovic Employee of: I’m a former employee of Sierra Oncology, Bryan Strouse Employee of: I’m an employee of Sierra Oncology, Christian Hassig Employee of: I am a former employee of Sierra Oncology, Guenter Weiss: None declared, Igor Theurl Grant/research support from: I have received research support from Sierra Oncology, Consultant of: I have consulted for Kymba Ltd.

Abstract
Dalbavancin, a lipoglycopeptide with prolonged half-life approved for the treatment of acute bacterial skin and soft tissue infections, can be used for the treatment of infections caused by gram-positive bacteria requiring long term treatment such as endocarditis, prosthetic joint infections (PJI) or osteomyelitis. Clinical data are limited in these settings. OBJECTIVES To evaluate indications, safety, tolerability and long-term outcomes of dalbavancin-treated patients. Patients and methods Our multicenter, retrospective study includes patients who received dalbavancin in Austria from September 2016 to March 2018. 90-day outcomes and tolerability were determined. RESULTS A total of 101 patients were included in 3 centers (57% male, median age 65 years). The treated infections were PJI (31%), osteomyelitis (29%), endocarditis (25%) and acute bacterial skin and soft tissue infections (12%). Concomitant use of other antimicrobial substances was common (63%). The mean total cumulative dose of dalbavancin was 3,357mg (±2,283mg). Clinical success rate was 89%. Side effects occurred in 3/101 patients. CONCLUSION In this real-life study dalbavancin was primarily used in off-label indications for treatment of PJI, osteomyelitis and endocarditis. Success rate was high (89%), tolerability and safety were excellent in this setting. Dalbavancin may therefore be used in these off-label indications as alternative treatment approach.

Abstract
Background Vocal fold (VF) scarring remains a therapeutic dilemma and challenge in modern laryngology. To facilitate corresponding research, we aimed to establish an in vitro fibrogenesis model employing human VF fibroblasts (hVFF) and the principles of macromolecular crowding (MMC). Methods Fibrogenesis was promoted by addition of transforming growth factor-β1 to standard medium and medium containing inert macromolecules (MMC). Hepatocyte growth factor (HGF) and Botox type A were tested for their antifibrotic properties in various doses. Experiments were analyzed with respect to the biosynthesis of collagen, fibronectin, and α-smooth muscle actin using immunofluorescence, silver stain and western blot. Results MMC led to favourable enhanced deposition of collagen and other extracellular matrix components, reflecting fibrotic conditions. Low doses of HGF were able to dampen profibrotic effects. This could not be observed for higher HGF concentrations. Botox type A did not show any effects. Conclusion Based on the principles of MMC we could successfully establish a laryngeal fibrogenesis model employing hVFF. Our finding of dose-dependent HGF effects is important before going into clinical trials in humans and has never been shown before. Our model provides a novel option to screen various potential antifibrotic compounds under standardized conditions in a short time.

Abstract
Triggering receptor expressed on myeloid cells-1 (TREM-1) is expressed on neutrophils and monocyte/macrophages and amplifies Toll-like receptor-mediated inflammation during infection. TREM-1 also exists in an antagonistic soluble form (sTREM-1) that has been used as a peripheral biomarker in sepsis, though the mechanisms of its release are not entirely clear. The requirement of TREM-1 in single microbial infections is controversial, with some studies showing a protective role and others a contribution to immunopathology. Furthermore, the role of membrane-bound and sTREM-1 in polygenic infections is currently unknown. In a mouse co-infection model where preceding viral infection greatly enhances bacteria co-infection, we now determine a mechanisms for the striking increase in sTREM-1 and the loss of TREM-1 on surface of neutrophils. We identified a matrix metalloproteinase (MMP)-9 cleavage site in TREM-1 and that the increase of MMP-9 in bronchoalveolar lavage fluid mirrors sTREM-1 release. In vitro studies with neutrophils and MMP-9 and the reduction of sTREM-1 in vivo after MMP-9 inhibition verifies that this enzyme cleaves TREM-1. Intriguingly, MMP-9 inhibition significantly reduces bacterial load and ensuing immunopathology in a co-infection model. This highlights MMP-9 inhibition as a potential therapeutic via blocking cleavage of TREM-1.

Abstract
BACKGROUND Divalent metals play important roles in maintaining metabolism and cellular growth of both eukaryotic hosts and invading microbes. Both metal deficiency and overload can result in abnormal cellular function or damage. Given its central role in host-pathogen interactions, subtle alterations of divalent metal homeostasis can occur in the course of infectious diseases which aim, from the host perspective, either to reduce the availability of respective metals to microbes or to use toxic metal accumulation to eliminate pathogens. AIMS To provide the reader with background information and clinical data on divalent metal homeostasis in host-pathogen interactions, how this affects the course of infectious disease and whether correction of metal disturbances has shown benefit in infections. SOURCES An in-depth analysis of PubMed articles related to the topic of this review published in English between 1970 and 2016 was performed. CONTENT From the microbial perspective, divalent metals are essential for growth and pathogenicity and to mount effective protection against antimicrobial host responses, including toxic radical formation. Microbes have evolved multiple strategies to control their access to divalent metals. From the clinical perspective, alterations of divalent metal levels may result in increased or decreased susceptibility to infection and often occur in response to infections. However, keeping in mind the strategies underlying such alterations, for which the term 'nutritional immunity' was coined, the uncritical correction of such divalent metal imbalances may cause harm to patients. This review addresses the role of the divalent metals iron, selenium, zinc, manganese and copper in infectious diseases from a mechanistic and clinical perspective. IMPLICATIONS We point out areas of research needed to expand our limited knowledge, hoping to improve the clinical management of patients with infections and to identify promising new targets for treatment by modulation of host or microbe divalent metal metabolism.

Abstract
Intravenous (IV) iron therapy is widely used in iron deficiency anaemias when oral iron is not tolerated or ineffective. Administration of IV-iron is considered a safe procedure, but severe hypersensitivity reactions (HSRs) can occur at a very low frequency. Recently, new guidelines have been published by the European Medicines Agency with the intention of making IV-iron therapy safer; however, the current protocols are still non-specific, non-evidence-based empirical measures which neglect the fact that the majority of IV-iron reactions are not IgE-mediated anaphylactic reactions. The field would benefit from new specific and effective methods for the prevention and treatment of these HSRs, and the main goal of this review was to highlight a possible new approach based on the assumption that IV-iron reactions represent complement activation-related pseudo-allergy (CARPA), at least in part. The review compares the features of IV-iron reactions to those of immune and non-immune HSRs caused by a variety of other infused drugs and thus make indirect inferences on IV-iron reactions. The process of comparison highlights many unresolved issues in allergy research, such as the unsettled terminology, multiple redundant classifications and a lack of validated animal models and lege artis clinical studies. Facts and arguments are listed in support of the involvement of CARPA in IV-iron reactions, and the review addresses the mechanism of low reactogenic administration protocols (LRPs) based on slow infusion. It is suggested that consideration of CARPA and the use of LRPs might lead to useful new additions to the management of high-risk IV-iron patients.

Abstract
STUDY QUESTION How is histiotrophic nutrition of the embryo secured during the first trimester of pregnancy? SUMMARY ANSWER Rather than specifically focusing on invasion into spiral arteries, extravillous trophoblasts also invade into uterine glands (endoglandular trophoblast) from the very beginning and open them toward the intervillous space. WHAT IS KNOWN ALREADY Extravillous trophoblasts can be found in close contact and within the lumen of uterine glands, sometimes replacing glandular epithelial cells. STUDY DESIGN, SIZE, DURATION As well as extensive screening of specimens from first trimester placentation sites in situ we used a previously established three-dimensional co-culture in vitro model system of first trimester villous explants with non-invaded decidua parietalis. PARTICIPANTS/MATERIALS, SETTING, METHODS First trimester placentas were obtained from elective terminations of pregnancies (n = 48) at 5-11 weeks of gestational age. A subset was processed for confrontation co-culture (n = 31). Invaded decidua basalis was obtained from 20 placentas. All tissues were sectioned, subsequently immunostained and immunodoublestained with antibodies against keratin 7 (KRT7), major histocompatibility complex, class I, G (HLA-G), matrix metallopeptidase 9 (MMP9), von Willebrand factor (VWF) and the appropriate Immunoglobulin G (IgG) negative controls. Replacement of endothelial/epithelial cells by extravillous trophoblasts was quantified semi-quantitatively. Additionally, hematoxylin and eosin-stained archival specimens from early implantation sites were assessed. MAIN RESULTS AND THE ROLE OF CHANCE The earliest available specimen was from around Day 10 after conception; already at this stage trophoblasts had penetrated into uterine glands and had started to replace the epithelium of the glands. Endoglandular trophoblasts replaced uterine glands in vitro and in situ and could be found in the lumen of invaded glands. Quantitative analysis revealed significantly more replacement of epithelial cells in glands (63.8 ± 22.1%) compared with endothelial cells in vessels (26.4 ± 8.8%). Accumulated detached glandular epithelial cells could be repeatedly observed in the lumen of invaded glands. Additionally, in areas of trophoblast invasion the glandular epithelium seemed to be completely disintegrated compared with glandular epithelium in the non-invaded parts of the decidua. Whole tissue specimens were used in vitro and in situ instead of cell lines; these systems mostly maintain the context of the in vivo situation. LIMITATIONS, REASONS FOR CAUTION This is a descriptive study supported by in vitro experiments. However, a histological section will always only be a snapshot and quantification from histological sections has its limitations. WIDER IMPLICATIONS OF THE FINDINGS This study further strengthens the hypothesis of histiotrophic nutrition of the embryo prior to the establishment of the maternal blood flow toward the placenta. Invasion of uterine glands by endoglandular trophoblasts may have more impact on the outcome of early pregnancy than assumed up to now.

Abstract
OBJECTIVE Acute inflammation induced by administration of Escherichia coli lipopolysaccharide endotoxin (LPS) reduces plasma concentrations of vitamin C and impairs vascular endothelium-derived nitric oxide (NO) bioactivity. We tested the hypothesis that systemically administered high dose vitamin C restores the endogenous anti-oxidant potential and improves NO-dependent vasodilatation in the forearm vasculature. DESIGN & SETTING 36 male subjects were enrolled in this balanced, placebo controlled cross-over study. Forearm blood flow (FBF) reactivity to acetylcholine (ACh) and glyceryl-trinitrate (GTN), a sensitive test for endothelial function, was assessed at baseline and 4h after LPS-administration (20 IU/kg i.v). The effect of two different doses of intravenous vitamin C (Vitamin C-Injektopas®), 320 mg/kg and 480 mg/kg over 2h, or placebo on forearm vascular function was studied after LPS. MAIN RESULTS LPS caused transient flu-like symptoms, decreased plasma vitamin C concentrations and reduced the ACh-dependent increase in FBF by up to 76%. Vitamin C at a mean plasma concentration of 3.2 or 4.9 mmol/L restored the response to ACh compared to baseline. CONCLUSION High dose systemic vitamin C recovers LPS-induced endothelium-dependent vasodilation in the forearm resistance vasculature. This provides a rationale for a further clinical study of the systemic vitamin C effect under inflammatory conditions.

Abstract
BACKGROUND Iron deficiency is a common and undertreated problem in inflammatory bowel disease (IBD). AIM To develop an online tool to support treatment choice at the patient-specific level. METHODS Using the RAND/UCLA Appropriateness Method (RUAM), a European expert panel assessed the appropriateness of treatment regimens for a variety of clinical scenarios in patients with non-anaemic iron deficiency (NAID) and iron deficiency anaemia (IDA). Treatment options included adjustment of IBD medication only, oral iron supplementation, high-/low-dose intravenous (IV) regimens, IV iron plus erythropoietin-stimulating agent (ESA), and blood transfusion. The panel process consisted of two individual rating rounds (1148 treatment indications; 9-point scale) and three plenary discussion meetings. RESULTS The panel reached agreement on 71% of treatment indications. 'No treatment' was never considered appropriate, and repeat treatment after previous failure was generally discouraged. For 98% of scenarios, at least one treatment was appropriate. Adjustment of IBD medication was deemed appropriate in all patients with active disease. Use of oral iron was mainly considered an option in NAID and mildly anaemic patients without disease activity. IV regimens were often judged appropriate, with high-dose IV iron being the preferred option in 77% of IDA scenarios. Blood transfusion and IV+ESA were indicated in exceptional cases only. CONCLUSIONS The RUAM revealed high agreement amongst experts on the management of iron deficiency in patients with IBD. High-dose IV iron was more often considered appropriate than other options. To facilitate dissemination of the recommendations, panel outcomes were embedded in an online tool, accessible via http://ferroscope.com/.
