Abstract
Abstract
Study question
Is basal antral follicle count (bAFC) taken on day 1 to 3 of stimulation a useful predictor of oocyte yield in that cycle, in women with diminished ovarian reserve (DOR)?
Summary answer
Basal AFC has moderate correlation with final oocyte yield. A median 75% of the antral follicle count is collected as oocytes.
What is known already
The current theory of folliculogenesis suggests that all follicles available for recruitment are visible on ultrasound in the ovary at the point when ovarian stimulation is applied. This implies a tight correlation between the AFC on day 1–3 of a stimulation cycle (bAFC) and the eventual number of follicles collected. We hypothesise that in women with diminished ovarian reserve who receive maximum stimulation basal AFC would be a useful predictor of final oocyte yield in that cycle.
Study design, size, duration
This was a prospective single centre, observational study in a tertiary referral hospital in London. 125 women with DOR underwent controlled ovarian stimulation between December 2018 and January 2021.
Participants/materials, setting, methods
All study participants were given an antagonist cycle with a starting stimulation dose of 450iu and remained on the same dose throughout their treatment. We assessed the correlation between bAFC taken on day 1–3 of the stimulation cycle and the total number of oocytes collected.
Main results and the role of chance
A total of 150 treatment cycles were included in the analysis. The median age was 37 (IQR 35 – 39). The median AMH was 6.0 (IQR 4.4 – 8.9) and the median FSH was 7.6 (IQR 5.7 – 9.4). The median bAFC at the start was 9 (IQR 6 – 11). The median total stimulation dose was 4050iu (IQR 4050 – 4500). The median oestradiol on day of trigger was 5906 (IQR 4166 – 7397) and median number of oocytes collected was 7 (IQR 5 – 9).
There was a moderate correlation between bAFC and the number of oocytes collected (r = 0.549, p = 0.005). The median ratio of oocytes collected over the number of antral follicles observed at the start was 72.7% (IQR 58.3 – 100).
Limitations, reasons for caution
We have standardised approach to AFC determination and have previously shown that AFC inter and intra-observer variability in our unit is low. Nevertheless, our study involved multiple operators for AFC determination which may introduce variability. Further variability may have been introduced at egg collection by varying technique.
Wider implications of the findings: Studies of antagonist protocol in good prognosis patients suggest poor correlation between basal AFC and oocyte yield. In contrast, our study shows that in a population of women with DOR basal AFC provides useful information which can be used to counsel women around the expected oocyte yield of their cycle.

Abstract
Thioredoxins (TRXs) are important proteins involved in redox regulation of metabolism. In plants, it has been shown that the mitochondrial metabolism is regulated by the mitochondrial TRX system. However, the functional significance of TRX h2, which is found at both cytosol and mitochondria, remains unclear. Arabidopsis plants lacking TRX h2 showed delayed seed germination and reduced respiration alongside impaired stomatal and mesophyll conductance, without impacting photosynthesis under ambient O2 conditions. However, an increase in the stoichiometry of photorespiratory CO2 release was found during O2 -dependent gas exchange measurements in trxh2 mutants. Metabolite profiling of trxh2 leaves revealed alterations in key metabolites of photorespiration and in several metabolites involved in respiration and amino acid metabolism. Decreased abundance of serine hydroxymethyltransferase and glycine decarboxylase (GDC) H and L subunits as well as reduced NADH/NAD+ ratios were also observed in trxh2 mutants. We further demonstrated that the redox status of GDC-L is altered in trxh2 mutants in vivo and that recombinant TRX h2 can deactivate GDC-L in vitro, indicating that this protein is redox regulated by the TRX system. Collectively, our results demonstrate that TRX h2 plays an important role in the redox regulation of mitochondrial photorespiratory metabolism.

Abstract
Photorespiration sustains photosynthesis in the presence of oxygen due to rapid metabolization of 2-phosphoglycolate, the major side-product of the oxygenase activity of Rubisco that also directly impedes carbon assimilation and allocation. Despite the fact that both the biochemical reactions and the underlying genetics are well characterized, information concerning the regulatory mechanisms that adjust photorespiratory flux is rare. Here, we studied the impact of mitochondrial-localized thioredoxin o1 (TRXo1) on photorespiratory metabolism. The characterization of an Arabidopsis (Arabidopsis thaliana) transfer DNA insertional line (trxo1-1) revealed an increase in the stoichiometry of photorespiratory CO2 release and impaired Gly-to-Ser turnover after a shift from high-to-low CO2 without changes in Gly decarboxylase (GDC) gene or protein expression. These effects were distinctly pronounced in a double mutant, where the TRXo1 mutation was combined with strongly reduced GDC T-protein expression. The double mutant (TxGT) showed reduced growth in air but not in high CO2, decreased photosynthesis, and up to 54-fold more Gly alongside several redox-stress-related metabolites. Given that GDC proteins are potential targets for redox-regulation, we also examined the in vitro properties of recombinant GDC l-proteins (lipoamide dehydrogenase) from plants and the cyanobacterium Synechocystis species strain PCC6803 and observed a redox-dependent inhibition by either artificial reducing agents or TRXo1 itself. Collectively, our results demonstrate that TRXo1 potentially adjusts photorespiration via redox-regulation of GDC in response to environmental changes.

Abstract
AIMS This study aimed to explore the possibility of using the Gluconacin from Gluconacetobacter diazotrophicus strain PAL5 in the biological control of diverse sugarcane phytopathogenic bacteria. METHODS AND RESULTS An in silico analysis was first employed to determine the phylogenetic relationship between Gram-negative/positive bacteriocin producers and Gluconacin. The analysis showed that this trait is widespread among tested bacterial species and a well-conserved gene within the Acetobacteraceae family. The bacteriocin gene (GDI_0415) present in the genome of strain PAL5 was than cloned in pDEST™17 and expressed in Escherichia coli BL21-AI™. A bioassay showed growth inhibition of Xanthomonas albilineans by the recombinant bacteriocin. Subsequent bioassays indicated different levels of antagonistic activity against the majority of the sugarcane phytopathogenic bacteria (Xanthomonas axonopodis pv. vasculorum, Acidovorax avenae subsp. avenae, Pseudomonas syringae pv. syringae, Xanthomonas vasicola pv. vasculorum). In addition, the bacteriocin was also antagonistic to some beneficial bacterial strains belonging to G. diazotrophicus and endophytic Bacillus species, which also colonize sugarcane plants. CONCLUSIONS The GDI_0415 gene, responsible for the production of Gluconacin, is well conserved within the Acetobacteraceae family and presented antagonistic activity against phytopathogenic and a few beneficial sugarcane bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY The production of a recombinant protein, named Gluconacin, opens new avenues for the agro-biotechnology application in agriculture, mainly with regard to the sugarcane crop.

Abstract
Telemedicine is already widely used in many telestroke networks and ensures stroke treatment close to the patient's home in rural and medically underserved areas. This is particularly effective when telemedicine is integrated into a stroke unit concept. While telemedically based thrombolysis therapy has become routine practice for many years, practical implementation of comprehensive mechanical thrombectomy and the related processes remains challenging. The main tasks for the future further include development of a structured stroke aftercare system in neurologically underserved areas and permanent assurance of high-quality stroke care in telemedically connected sites.

Abstract
Large hemispheric infarction (LHI), synonymously called malignant middle cerebral artery (MCA) infarction, is a severe neurological disease with a high mortality and morbidity. Treating physicians as well as relatives are often faced with few and low quality data when attempting to apply optimal treatment to these patients and make decisions. While current stroke treatment guidelines focus on risk factors, prevention and acute management, they include only limited recommendations concerning intensive care management of LHI. The Neurocritical Care Society (NCS) and the German Society for Neurocritical and Emergency Medicine (DGNI) organized an interdisciplinary consensus conference on intensive care management of LHI to meet this demand. European and American experts in neurology, neurocritical care, neurosurgery, neuroradiology and neuroanesthesiology were selected based on their expertise and research focus. Subgroups for several main topics elaborated a number of central clinical questions concerning this topic and evaluated the quality of the currently available data according to the grading of recommendation assessment, development and evaluation (GRADE) guideline system. Subsequently, evidence-based recommendations were compiled after weighing the advantages against the disadvantages of certain management options. This is a commented abridged version of the results of the consensus conference.

Abstract
BACKGROUND AND PURPOSE Perfusion and angiographic imaging using intravenous contrast application to evaluate stroke patients is now technically feasible by flat detector CT performed by the angiographic system. The aim of this pilot study was to show the feasibility and qualitative comparability of a novel flat detector CT dynamic perfusion and angiographic imaging protocol in comparison with a multimodal stroke MR imaging protocol. MATERIALS AND METHODS In 12 patients with acute stroke, MR imaging and the novel flat detector CT protocol were performed before endovascular treatment. Perfusion parameter maps (MTT, TTP, CBV, CBF) and MIP/volume-rendering technique images obtained by using both modalities (MR imaging and flat detector CT) were compared. RESULTS Comparison of MIP/volume-rendering technique images demonstrated equivalent visibility of the occlusion site. Qualitative comparison of perfusion parameter maps by using ASPECTS revealed high Pearson correlation coefficients for parameters CBF, MTT, and TTP (0.95-0.98), while for CBV, the coefficient was lower (0.49). CONCLUSIONS We have shown the feasibility of a novel dynamic flat detector CT perfusion and angiographic protocol for the diagnosis and triage of patients with acute ischemic stroke. In a qualitative comparison, the parameter maps and MIP/volume-rendering technique images compared well with MR imaging. In our opinion, this flat detector CT application may substitute for multisection CT imaging in selected patients with acute stroke so that in the future, patients with acute stroke may be directly referred to the angiography suite, thereby avoiding transportation and saving time.

Abstract
PURPOSE It has been reported that the extent of intravascular thrombi and the quality of collateral filling in computed tomography (CT) angiography are predictive for the clinical outcome in patients with acute stroke. We hypothesized that multi-phase four-dimensional CTA (4D-CTA) allows better assessment of clot burden and collateral flow compared with arterial single-phase CTA (CTA). METHODS In 49 patients (33 female; age: 77 ± 12 years) with acute anterior circulation stroke, CTA and 4D-CTA reconstructed from dynamic perfusion CT data were analyzed for absolute thrombus length (TL), clot burden score (CBS), and collateral score (CS). The length of the filling defect was also defined on thin-slice nonenhanced CT as corresponding hyperdense middle cerebral artery sign (HMCAS) when present. RESULTS There was good correlation (r = 0.62, p < 0.01) between the length of HMCAS (1.29 ± 0.62 cm) and TL in 4D-CTA (1.22 ± 0.51 cm). 4D-CTA and CTA significantly varied (p < 0.01) in TL (1.42 ± 0.73 cm (CTA) versus 1.11 ± 0.62 cm (4D-CTA)), CBS (median: 5, interquartile range: 4-7 (CTA) versus median: 6, interquartile range: 5-8 (4D-CTA); p < 0.001), and CS (median: 2, interquartile range: 1-2 (CTA) versus median: 3, interquartile range: 2-3 (4D-CTA); p < 0.001). Accordingly, CTA significantly overrated clot burden and underestimated collateral flow. CONCLUSIONS 4D-CTA more closely defines clot burden and collateral supply in anterior circulation stroke than CTA, implicating an additional diagnostic benefit.

Abstract
OBJECTIVES Current population-based surveys in Europe on the prevalence of dietary supplement (DS) use in older individuals are scarce. The aim of the present study was to investigate patterns, prevalence and determinants of non-herbal DS use in aged subjects. Furthermore, the intake amounts of vitamins and minerals from supplements were assessed. DESIGN Cross-sectional. SETTING Data on supplement use were available from an age- and sex-stratified random sample of the German population-based KORA (Cooperative Health Research in the Region of Augsburg)-Age study. PARTICIPANTS 1,079 persons who were born in or before the year 1943. MEASUREMENTS Use of dietary supplements and medications during the last seven days was recorded in a face-to-face interview in 2009. Participants were asked to bring all packages of ingested preparations to the study center. Not only vitamin/mineral supplements, but also non-vitamin non-mineral non-herbal supplements and drugs containing vitamins and minerals were coded as DS. RESULTS The age-standardized prevalence of DS intake was 54.3% in women and 33.8% in men, respectively. The most commonly supplemented mineral and vitamin, respectively, was magnesium (31.9%) and vitamin D (21.5%) in women and magnesium (18.0%) and vitamin E (12.0%) in men. The highest intakes, compared to the German Dietary Reference Intakes, were reported for biotin, vitamin B6 and B1. Excessive intakes (equal or above the European Tolerable Upper Intake Levels (UL)) were observed especially for magnesium and vitamin E. 20.2% of the women and 32.5% of the men who took magnesium supplements regularly exceeded the UL for magnesium. In case of vitamin E this was true for 8.0% of the women and 13.6% of the men. Determinants of DS use were sex, education, smoking, physical activity, neurological diseases, and stroke. CONCLUSION A high proportion of the general population aged 65 years and older in Southern Germany uses DS, especially supplements containing vitamins/minerals. The supplementation of vitamin D can be regarded as favorable in this age group, whereas the excessive intakes of vitamin E might be a cause of concern.

Abstract
Immunologically mediated heparin-induced thrombocytopenia (HIT) is a thrombotic disease caused by antibodies occurring after heparin exposure. Thrombocytopenia occurs within a few days after heparin exposure, about half of HIT-patients develop venous or arterial thrombotic complications. Neurological complications of HIT are mainly ischaemic stroke and sinus vein thrombosis. To ensure the primary clinical diagnosis functional and immunological assays for antibody detection are available. The probability for the occurrence of HIT depends on the nature of heparin employed (LMWH vs. UFH) and individual patient characteristics such as gender and primary disease (medical vs. surgical patients). In the case of suspected HIT heparin administration should be discontinued immediately and replaced by an alternative anticoagulation to prevent the expansion or development of further thrombotic complications. Herein we report a case of a patient suffering from HIT-associated embolic cerebral ischaemic stroke.

Abstract
The aim of this paper is to review new developments in the intensive care of patients with space-occupying middle cerebral artery infarctions. Elevated blood pressure should not be treated; however, there is no scientific basis to induce arterial hypertension in these patients. It is not recommended generally to nurse the patients in a position with the head elevated. If therapy is targeted for an optimum cerebral perfusion pressure, the patients should be nursed in a flat position. Decompressive surgery is associated with a marked reduction in an otherwise high mortality. The functional outcome after surgery is similar to the outcome of the survivors after conventional treatment alone. Treatment options for an acutely raised intracranial pressure are mannitol or hypertonic saline solutions, although the long-term effects have not been ascertained yet. There is not enough evidence supporting a prophylactic standard therapy with hypertonic solutions. Patients who require artificial ventilation can be safely ventilated using PEEP or an inverse inspiration/expiration ratio, if the blood pressure is monitored and a possible drop of the arterial blood pressure is treated. Corticoids and hemodilution are obsolete therapies in these patients.

Abstract
Recurrent optic neuritis is frequently observed in multiple sclerosis (MS) and is a typical finding in neuromyelitis optica (NMO). Patients that lack further evidence of demyelinating disease are diagnosed with RION (recurrent isolated optic neuritis) or CRION (chronic relapsing inflammatory neuropathy) if they require immunosuppressive therapy to prevent further relapses. The etiology and disease course of this rare condition are not well defined. We studied a series of 10 patients who presented with recurrent episodes of isolated optic neuritis (ON, n=57) and were followed over a median of 3.5 years. Visual acuity was severely reduced at the nadir of the disease (20/200 to 20/800). All patients had MRI non-diagnostic for MS/NMO and were aquaporin-4 antibody negative. Six patients fulfilled the CRION criteria. In two of these a single ON followed by a long disease-free interval preceded development of CRION for years, suggesting the conversion of an initially "benign" isolated ON into the chronic relapsing course. Cerebrospinal fluid (CSF) analysis revealed mild pleocytosis in 5 patients, identical oligoclonal bands in serum and CSF were observed in 2 patients, while the others remained negative. In conclusion, recurrent ON is a disease entity that requires aggressive glucocorticoid and eventually long-term immunosuppressive therapy to prevent substantial visual impairment.

Abstract
Intracerebral hemorrhage (ICH) is one of the most detrimental sub-types of stroke and accounts for 10-15% of all strokes Qureshi et al. (Lancet 373(9675):1632-1644, 2009). ICH has an incidence of 10-30 cases per 100,000 people/year which is increasing and expected to double by the year 2050 Qureshi et al. (N Engl J Med 344 (19):1450-1460, 2001). Mortality rates still remain poor (30-50%) and functional dependency after ICH is high (~75%) van Asch et al. (Lancet Neurol 9 (2):167-176, 2010). Up to now, all randomized controlled trials investigating treatment approaches in ICH have failed to document improvements on clinical endpoints Mayer et al. (N Engl J Med 358 (20):2127-2137, 2008); Brouwers and Goldstein (Neurotherapeutics 9 (1):87-98, 2012). Only a specialized treatment of severely injured patients at dedicated neuro intensive care units [NICU] has been shown to be beneficial Qureshi et al. (Lancet 373(9675):1632-1644, 2009); Suarez et al. (Crit Care Med 32 (11):2311-2317, 2004). Currently, ongoing trials are investigating aggressive blood pressure lowering, hemostatic therapies, different operative strategies, intraventricular thrombolysis as well as neuroprotective approaches, and brain edema therapies. This review will summarize advanced treatment strategies and novel approaches which are currently under investigation.

Abstract
Induced therapeutic hypothermia (TH) is defined as a controlled reduction of the core body temperature below the physiological range. While TH is neuroprotective in many different models of brain injury, it is only recommended for patients after cardiopulmonary resuscitation and newborns suffering from perinatal hypoxic-ischemic encephalopathy (HIE). Although a strong association exists between elevated body core temperature (fever) and worsening of outcome, TH has so far not been proven to influence outcome after ischemic stroke, intracerebral hemorrhage or subarachnoidal hemorrhage because of insufficient clinical data. This review summarizes the data on TH for different clinical indications and discusses relevant aspects of its use in neurological intensive care units.

Abstract
Persistent breeding-induced endometritis is ranked as the third most common medical problem in the adult mare and leads to enormous economic loss in horse breeding. In mares suffering from persistent breeding-induced endometritis, increased amounts of intrauterine (i.u.) fluid or viscous mucus in estrus or after breeding may act as a barrier for sperm and can contribute to low fertility. Current therapies of these mares aim to eliminate i.u. fluid and mucus by uterine lavage and/or administration of ecbolic drugs. Recently, i.u. administration of N-acetylcysteine (NAC) has been shown to support therapy in mares with endometritis. It was the objective of the present study to investigate effects of an oral administration of NAC on the viscosity of i.u. fluid in estrous mares. It was hypothesized that oral treatment with NAC reduces the viscosity of i.u. fluid and has a positive effect on the inflammatory response of the endometrium. Mares (n = 12) were included in the study as soon as estrus was detected (ovarian follicle >3.0 cm and endometrial edema), which was defined as Day 1. They were randomly assigned to a treatment (10 mg/kg NAC on Days 1-4) or a control group (no treatment). On days 1 and 5 i.u. mucus was collected and its rheologic properties were accessed. On Day 5, endometrial biopsies were obtained and evaluated for integrity of the luminal epithelium, number of polymorphonuclear neutrophils (PMN), staining for cyclooxygenase 2 (COX2), staining with Kiel 67 antigen (Ki-67), lectins and periodic acid Schiff (PAS). In the treatment group, viscosity of i.u. mucus increased significantly between Days 1 and 5 (P < 0.05), while no differences were found in control mares (n.s.). At no time were significant differences between treated and control mares seen. Integrity of epithelium was not affected. After NAC treatment the mean number of PMN in endometrial biopsies was significantly lower compared to mares of the control group (1.9 ± 0.3 vs. 4.8 ± 0.4; P < 0.05). Nuclear immunostaining for COX2 was significantly lower after NAC treatment compared to control mares (P < 0.05). Score for PAS and Alcain staining of mucus in deep uterine glands differed significantly between groups (both P < 0.05). We conclude that oral NAC treatment does not reduce viscosity of uterine mucus but has an antiinflammatory effect on the equine endometrium.

Abstract
Aim: The aim of this prospective clinical study was to assess whether it would be possible to reduce the rate of re-excisions and improve the quality using CMOS technology or digital breast tomosynthesis (DBT) compared to a conventional FFDM system. Material and Methods: An invasive breast cancer (BI-RADS 5) was diagnosed in 200 patients in the period from 5/2011 to 1/2012. After histological verification, a breast-conserving therapy was performed with intraoperative imaging. Three different imaging systems were used: 1) Inspiration™ (Siemens, Erlangen, Germany), amorphous selenium, tungsten source, focus 0.1 mm, resolution 85 µm pixel pitch, 8 l/mm as the standard; 2) BioVision™ (Bioptics, Tucson, USA), flat panel photodiode array, tungsten source, focus 0.05, resolution 50 µm pixel pitch, 12 l/mm; 3) Tomosynthesis (Siemens, Erlangen, Germany), amorphous selenium, tungsten source, focus 0.1 mm, resolution 85 µm pixel pitch, 8 l/mm, range: 50°, 25 projections, scan time > 20 s, geometry: uniform scanning, reconstruction: filtered back projection. The 600 radiograms were prospectively shown to 3 radiologists. Results: Out of a total of 200 patients with histologically confirmed breast cancer (BI-RADS 6) 156 patients required no further operative therapy (re-excision) after breast-conserving therapy. A retrospective analysis (n = 44) showed an increase in sensitivity with tomosynthesis compared to the BioVision™ (CMOS technology) and the Inspiration™ at a magnification of 1.0 : 1.0 of 8 % (p < 0.05), i.e. re-excision would not have been necessary in 16 patients with tomosynthesis. Conclusions: The sensitivity of tomosynthesis for intraoperative radiography is significantly (p < 0.05) higher compared to both CMOS technology and an FFDM system with a conventional detector. Additional studies using higher magnification, e.g. 2.0 : 1.0, but no zooming will be necessary to evaluate the method further.

Abstract
Purpose: Experimental study of a new system for digital 2D and 3D full-field mammography (FFDM) using a high resolution detector based on two shifts of a-Se. Material and Methods: Images were acquired using the new FFDM system Amulet® (FujiFilm, Tokio, Japan), an a-Se detector (receptor 24 × 30 cm2, pixel size 50 µm, memory depth 12 bit, spatial resolution 10 lp/mm, DQE > 0.50). Integrated in the detector is a new method for data transfer, based on optical switch technology. The object of investigation was the Wisconsin Mammographic Random Phantom, Model 152A (Radiation Measurement Inc., Middleton, WI, USA) and the same parameters and exposure data (Tungsten, 100 mAs, 30 kV) were consistently used. We acquired 3 different pairs of images in the c-c and ml planes (2D) and in the c-c and c-c planes with an angle of 4 degrees (3D). Five radiologists experienced in mammography (experience ranging from 3 months to more than 5 years) analyzed the images (monitoring) which had been randomly encoded (random generator) with regard to the recognition of details such as specks of aluminum oxide (200-740 µm), nylon fibers (0.4-1.6 mm) and round lesions/masses (diameters 5-14 mm), using special linear glasses for 3D visualization, and compared the results. Results: A total of 225 correct positive decisions could be detected: we found 222 (98.7 %) correct positive results for 2D and 3D visualization in each case. Conclusion: The results of this phantom study showed the same detection rates for both 2D and 3D imaging using full field digital mammography. Our results must be confirmed in further clinical trials.
