Abstract
Ascertaining the collective viability of cells in different cell culture conditions has typically relied on averaging colorimetric indicators and is often reported out in simple binary readouts. Recent research has combined viability assessment techniques with image-based deep-learning models to automate the characterization of cellular properties. However, further development of viability measurements to assess the continuity of possible cellular states and responses to perturbation across cell culture conditions is needed. In this work, we demonstrate an image processing algorithm for quantifying features associated with cellular viability in 3D cultures without the need for assay-based indicators. We show that our algorithm performs similarly to a pair of human experts in whole-well images over a range of days and culture matrix compositions. To demonstrate potential utility, we perform a longitudinal study investigating the impact of a known therapeutic on pancreatic cancer spheroids. Using images taken with a high content imaging system, the algorithm successfully tracks viability at the individual spheroid and whole-well level. The method we propose reduces analysis time by 97% in comparison with the experts. Because the method is independent of the microscope or imaging system used, this approach lays the foundation for accelerating progress in and for improving the robustness and reproducibility of 3D culture analysis across biological and clinical research.

Abstract
BACKGROUND Filgotinib 200 mg (FIL200) is an approved treatment for adults with moderately to severely active ulcerative colitis (UC). AIM To report integrated safety data from the phase 2b/3 SELECTION study (NCT02914522) and its ongoing long-term extension study SELECTIONLTE (NCT02914535). METHODS Safety outcomes were analysed in adults with moderately to severely active UC who received FIL200, filgotinib 100 mg (FIL100) or placebo once daily throughout the 11-week SELECTION induction study, the 47-week SELECTION maintenance study (if applicable) and SELECTIONLTE (if applicable). Exposure-adjusted incidence rates (EAIRs) per 100 censored patient-years of exposure with 95% confidence intervals were reported for treatment-emergent adverse events (AEs). Certain AE data were presented in subgroups, including age and prior biologic exposure status. RESULTS This interim analysis included 1348 patients representing 3326.2 patient-years of exposure. Baseline characteristics of patients entering SELECTION were similar across treatment groups. EAIRs for serious infection, thromboembolic events and major adverse cardiovascular events (MACE) were consistently low across treatment groups. Most patients with MACE had cardiovascular risk factors. The EAIR for herpes zoster was numerically higher for FIL200 than for placebo. Infection incidences were numerically higher in biologic-experienced than biologic-naive patients. Higher incidences of certain AEs in patients 65 years of age or older were as expected. Four deaths occurred, including three cardiovascular deaths, none of which was considered related to filgotinib. CONCLUSION FIL200 and FIL100 were well tolerated with no unexpected safety signals in patients with moderately to severely active UC, regardless of previous biologic exposure or age. CLINICALTRIALS GOV IDENTIFIERS (NCT NUMBERS) NCT02914522, NCT02914535.

Abstract
BACKGROUND AND AIMS The efficacy of new therapies for ulcerative colitis [UC] is usually influenced by previous biologic use. These post hoc analyses of SELECTION, a placebo-controlled phase 2b/3 trial in patients with moderately to severely active UC, evaluated the efficacy of filgotinib, an oral Janus 1 kinase preferential inhibitor, with respect to prior biologic failure. METHODS The effect of filgotinib 200 mg (FIL200) relative to placebo was compared in biologic-naïve and biologic-failed patient groups, and in further subgroups by number of failed biologics [1 or >1], biologic mechanism of action [MoA] classes [1 or 2] and tumour necrosis factor [TNF] antagonists [1 or >1]. Odds ratios [ORs] for clinical remission at week 10 [induction] and hazard ratios [HRs] for protocol-specific disease worsening [PSDW] from week 11 to week 58 [maintenance] were calculated. RESULTS At week 10, FIL200-treated patients were more likely to achieve clinical remission than placebo-treated patients in the biologic-naïve (OR [95% confidence interval, CI]: 1.98 [1.14-3.44]) and biologic-failed (3.91 [1.33-11.48]) groups. During maintenance, FIL200-treated patients had a reduced risk of PSDW in the biologic-naïve (HR [95% CI]: 0.22 [0.11-0.44]) and biologic-failed (0.22 [0.12-0.40]) groups, and in all biologic-failed subgroups (except >1 TNF antagonist failure). The data suggest that the likelihood of PSDW at week 58 increased with increasing numbers of failed biologics. CONCLUSIONS FIL200 induced and maintained benefits relative to placebo regardless of previous biologic use; however, the estimated therapeutic benefit was greatest in biologic-naïve patients and patients previously treated with one biologic or biologic MoA class.

Abstract
Abstract
Introduction
Although the relationships amongst sleep, pain and anxiety have been evidenced, the underlying neurological mechanisms remain elusive. Primary dysmenorrhea is a good model of spontaneous pain with clear painful (menstruation, state) and pain free (e.g., peri-ovulatory phase, trait) conditions. We sought to investigate the state- and trait-related neural signatures that link sleep and anxiety in primary dysmenorrhea.
Methods
Thirty female subjects with primary dysmenorrhea and 30 healthy female controls completed resting-state functional magnetic resonance imaging, the State-Trait Anxiety Inventory and sleep quality assessments during menstruation and peri-ovulatory phases. As we have reported that there was altered default mode network in the primary dysmenorrhea, posterior parietal cortex (PPC) was therefore chosen as the seed to elucidate the functional connectivity that may correlate with sleep and anxiety.
Results
The primary dysmenorrheic subjects exhibited sleep disturbances throughout the menstrual cycle with increased state anxiety. The primary dysmenorrheic subjects demonstrated significantly higher correlations between the sleep quality and the PPC-insula and -putamen functional connectivity during the peri-ovulatory phase. During menstruation, the primary dysmenorrheic subjects demonstrated significantly lower correlations between their state-anxiety scores and the PPC-occipital cortex functional connectivity.
Conclusion
After regressing out the effects of trait anxiety, the correlation between sleep quality and the PPC-putamen functional connectivity was not significant, indicating anxiety-mediated sleep-pain relationship. The PPC-insula functional connectivity, by contrast, was remained significant. Furthermore, state anxiety was associated with the PPC-occipital cortex functional connectivity that was significantly impaired in primary dysmenorrheic subjects. These findings hinted pain and anxiety mediating sleep quality in different neurological circuits.

Abstract
PURPOSE OF INVESTIGATION To compare the effects of desogestrel (DSG) 150 mcg/ethinyl estradiol (EE) 20 mcg for 21 days followed by either seven days of EE ten mcg (21/7-active) or no treatment (DSG/EE+no Tx) on hemostatic markers. MATERIALS AND METHODS This was a randomized, multicenter, open-label study that enrolled healthy premenopausal women. Non-inferiority of 21/7-active to DSG/EE+no Tx was determined if the upper limit of the two-sided 95% CI of the mean treatment difference in prothrombin fragment 1+2 (F1+2) over 24 weeks between groups was < 130 pmol/L. RESULTS 246 subjects (n = 125, 21/7-active; n = 121, DSG/EE+no Tx) comprised the primary analysis. Mean F1+2 levels increased in both 21/7-active and DSG/EE+no Tx regimens (least square [LS] mean changes +45 pmol/L and +56.8 pmol/L, respectively). LS mean treatment difference was -11.8 pmol/L (95% CI: -54.8, 31.2). CONCLUSION The effect of adding EE ten mcg to the seven-day hormone-free interval of DSG/EE on F1+2 levels was non-inferior to traditional DSG/EE.

Abstract
Cerebral venous thrombosis (CVT) has usually been ascribed to prothrombotic conditions, oral contraceptives, pregnancy, malignancy, infection, head injury or mechanical precipitants. The case reported here illustrates two rare causes of CVT observed in the same patient: the presence of antiphospholipid antibodies associated with an asymptomatic cryptogenic organising pneumopathy (COP) which were considered the origin of the venous cerebral thrombosis and heparin-induced thrombocytopenia (HIT) which was responsible for the worsening of the thrombosis observed a few days after the introduction of treatment. Moreover, we provide here additional positive experience in the treatment of both, CVT and HIT, by fondaparinux with bridging to warfarin given their successful evolution under this anticoagulant option.

Abstract
Animals subjected to maternal separation stress during the early stages of development display behavioural, endocrine and growth factor abnormalities that mirror the clinical findings in anxiety/depression. In addition, maternal separation has been shown to exacerbate the behavioural deficits induced by 6-hydroxydopamine (6-OHDA) in a rat model of Parkinson's disease. In contrast, voluntary exercise reduced the detrimental effects of 6-OHDA in the rat model. The beneficial effects of exercise appeared to be largely due to compensation in the non-lesioned hemisphere. The aim of the present study was to investigate whether voluntary exercise for 3 weeks could reverse the effects of maternal separation in rats challenged with the neurotoxin 6-OHDA infused into the medial forebrain bundle after 1 week of exercise, at postnatal day 60. The rats were killed 2 weeks later, at postnatal day 74. Their brains were dissected and the hippocampus rapidly removed for proteomic analysis by isobaric tagging (iTRAQ) and quantification of peptides by matrix-assisted laser desorption/ionization tandem mass spectrometry (MALDI-MS/MS). Maternal separation upregulated hippocampal proteins functionally involved in energy metabolism (nucleoside diphosphate kinase B, enolase and triosephosphate isomerase) and synaptic plasticity (α-synuclein, tenascin-R, Ba1-667, brevican and neurocan core protein) in the non-lesioned hemisphere. Exercise reversed many of these changes by downregulating the levels of hippocampal proteins functionally associated with energy metabolism (nucleoside diphosphate kinase B, enolase and triosephosphate isomerase) and synaptic plasticity (α-synuclein, tenascin-R, Ba1-667, brevican and neurocan core protein) in the non-lesioned hemisphere of rats subjected to maternal separation. Exercise and maternal separation therefore appeared to have opposing effects on the hippocampus in the non-lesioned hemisphere of the rat brain. Exercise seemed partly to reverse the effects of maternal separation stress on these proteins in the non-lesioned hemisphere. The partial reversal of maternal separation-induced proteins by exercise in the non-lesioned side sheds some insight into the mechanism by which exercise alters the molecular role players involved in determining the consequences of early life stress.

Abstract
Abstract
T-cell deficiency secondary to cytotoxic agents, viral assaults or ageing predisposes to defective adaptive immunity. Therefore, therapeutic approaches to enhance thymic output leading to T cell reconstitution are of clinical importance. We develop a novel synthetic fusion cytokine between Granulocyte-macrophage colony stimulating factor (GM-CSF) and Interleukin 7 Fusion Transgene (GIFT7). In vitro, GIFT7 acts as a hyperagonist for the IL7 receptor (IL7R) leading to hyperphosphorylation of STAT5. To test the effect of GIFT7 on IL7R-expressing primary thymocytes, we dissociated normal thymii from C57BL/6 mice and exposed unfractionated thymic cells in vitro to GIFT7 for 5 days. We observed a marked anti-apoptotic and proliferative response in CD3+CD4-CD8+ single-positive CD8 (SPCD8) and CD4-CD8-CD44+CD25- double negative 1 (DN1) T cell precursors in both αβ and γδ T cell lineage. In vivo, intravenous administration of recombinant GIFT7 at 5 µg/kg daily for 2 days into non-irradiated mice leads to a significant 2 fold increase in thymic DN1 population after 7 days. After 14 days, there was a subsequent 100% increase in total thymocyte number which returned to baseline at day 35. We propose the use of GIFT7 as a novel IL7R targeted thymopoietic growth factor for the treatment of catastrophic human immune deficient ailments characterized by thymic involution such as congenital or HIV-mediated acquired immunodeficiency, post-chemotherapy/radiation therapy and ageing.

Abstract
Abstract
T-cell based immunotherapy represents a promising strategy for chronic viral infections or malignancies. However, its efficacy depends on the infused T cell fitness in vivo. Indeed, T cell exhaustion via the upregulation of PD-1 reflects the maladaptive immune response as the root cause of effector cell failure. To address this issue, we report the development of a novel synthetic fusion cytokine between Granulocyte-macrophage colony stimulating factor (GM-CSF) and Interleukin 7 Fusion Transgene (GIFT7). We show that GIFT7 leads to a hyperagonistic response manifest by increased pSTAT5 and proliferation in CD3+/CD127+ cells. GIFT7 also selectively expand a CD8+ subset from pre-activated T cells with a Central Memory phenotype defined as CD8+CD44+CD62L+CCR7+KLRG-CD27+PD1-, hereafter GIFT7CD8. Adoptive transfer of OTI-derived GIFT7CD8 into OVA+EG7-bearing mice leads to a significant anti-tumor effect. Furthermore, GIFT7CD8 persist long-term whilst IL2-actiaved CD8 T-cells are undetected. We also demonstrate the unique expansive effect of the human ortholog of GIFT7 on peripheral blood mononuclear cells (PBMC) derived from non-human primates (NHP) and humans, in that GIFT7 stimulation of pre-activated PBMC leads to T cell proliferation without exhaustion (Ki67hi and PD1low) in CD4+, CD8+, and CD4-CD8- compartments. This observation supports the use of GIFT7 primed T-cells for chronic viral infections or malignancies where an inadequate T cell response is a common feature.

Abstract
AIMS/HYPOTHESIS Glucagon-like peptide 1 (GLP-1) receptor (GLP-1R) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors attenuate postprandial lipaemia through mechanisms that remain unclear. As dyslipidaemia is a contributing risk factor for cardiovascular disease in type 2 diabetes, we examined the mechanisms linking pharmacological and physiological regulation of GLP-1 action to control of postprandial lipid metabolism. METHODS Postprandial lipid synthesis and secretion were assessed in normal and fructose-fed hamsters and in wild-type mice that were treated with or without sitagliptin. Apolipoprotein B-48 (ApoB-48) synthesis and secretion were also examined in primary enterocyte cultures. The importance of exogenous vs endogenous GLP-1R signalling for regulation of intestinal lipoprotein synthesis and secretion was assessed in mice and hamsters treated with the GLP-1R agonist exendin-4, the GLP-1R antagonist exendin(9-39) and in Glp1r (+/+) vs Glp1r (-/-) mice. RESULTS Sitagliptin decreased fasting plasma triacylglycerol, predominantly in the VLDL fraction, as well as postprandial triacylglycerol-rich lipoprotein (TRL)-triacylglycerol, TRL-cholesterol and TRL-ApoB-48 in hamsters and mice. GLP-1R activation with exendin-4 alone also decreased plasma and TRL-ApoB-48 in hamsters and mice, and reduced secretion of ApoB-48 in hamster enterocyte cultures. Conversely, blockade of endogenous GLP-1R signalling by the antagonist exendin(9-39) or genetic elimination of GLP-1R signalling in Glp1r (-/-) mice enhanced TRL-ApoB-48 secretion in vivo. Co-administration of exendin(9-39) also abolished the hypolipidaemic effect of sitagliptin. CONCLUSIONS/INTERPRETATION Potentiation of endogenous incretin action via DPP-4 inhibition or pharmacological augmentation of GLP-1R signalling reduces intestinal secretion of triacylglycerol, cholesterol and ApoB-48. Moreover, endogenous GLP-1R signalling is essential for the control of intestinal lipoprotein biosynthesis and secretion.
