The Japan Endoscopy Database Project was initiated to develop the world's largest endoscopy data repository. This study describes the first phase of the colonoscopy project in Japan.

Data were aggregated offline by integrating information from the endoscopy database software from January 2015 through March 2017. The study population included all patients who underwent colonoscopy at eight centers.

A total of 31,395 patients who underwent 38,497 colonoscopy procedures were registered. The majority of procedures were performed for screening (n=14,156), followed by fecal immunochemical test positivity (n=3960), abdominal symptoms (n=3864), post-colorectal surgery surveillance (n=3431), post-endoscopic treatment surveillance (n=3757), thorough pre-treatment examination (n=2822), and therapeutic purposes (n=6507). In the screening group, advanced cancers, early cancers, and adenomas were diagnosed endoscopically in 2.1%, 1.3%, and 28.7% of cases, respectively, while in the fecal immunochemical test-positive group, they were diagnosed in 2.5%, 1.9%, and 41.6% of cases, respectively. The incidence of complications was 0.177% and 0.152% in the screening and fecal immunochemical test-positive groups, respectively. The therapeutic procedures included 1446 cold forceps polypectomy procedures, 4770 cold snare polypectomy procedures, 368 hot biopsies, 2998 hot snare polypectomy procedures, 9775 endoscopic or piecemeal endoscopic mucosal resections, and 1660 endoscopic submucosal dissections. A total of 173 procedure-related complications (0.82%) occurred in 21,017 therapeutic procedures performed in 15,744 patients.

The first phase of the Japan Endoscopy Database Project established the proportions of the diagnostic and therapeutic colonoscopy procedures, and complication rates in real-world settings.

The objective of this exploratory study was to determine the presence and correlates of self-reported cognition in a sample of haematological cancer patients who had undergone allogeneic stem cell transplantation (SCT).

Haematological cancer patients (n=30) who had undergone allogeneic SCT between one and fiveyears previously and age-matched control participants (n=30) completed questionnaires assessing cognition, affect, sleep quality and fatigue and an assessment of premorbid IQ.

Patients reported significantly poorer perceived cognitive ability (d=1.12) and greater perceived cognitive impairment (d=0.96) than controls. Lower fatigue was significantly associated with greater perceived cognitive ability (r=0.75 patients and controls) and less perceived cognitive impairment (r=0.80 patients; r=0.57 controls). Interestingly, depression was significantly correlated with perceived cognitive ability in the control group only (r=0.80). Hierarchical multiple regressions showed that fatigue was a significant predictor of perceived cognitive ability in patients, accounting for 56% of the variance.

This study established that self-reported cognitive ability and cognitive impairment was significantly poorer in haematological cancer patients than controls. Furthermore, fatigue was significantly associated with perceived cognitive ability in patients. Future research should focus on identifying interventions that target fatigue in allogeneic SCT recipients in order to improve quality of life throughout survivorship.

Living kidney donation is questionable when eGFR is 55 years) in a population of 1825 French living kidney donors with a median follow-up of 5.9 years. In donors younger than 45, postdonation eGFR, absolute- and relative-eGFR variation were not different between the three groups. For older donors, postdonation eGFR was higher in S90 than in S80 or Sage but other comparators were identical. Postdonation eGFR slope was comparable between all groups. Our results are in favour of in-depth screening for all candidates to donation with a normal eGFR for age.Bathymodiolinae mussels are typical species in deep-sea cold seeps and hydrothermal vents and an ideal model for investigating chemosynthetic symbiosis and the influence of high hydrostatic pressure on deep-sea organisms. Herein, the potential influence of depressurization on DNA fragmentation and cell death in Bathymodiolinae hosts and their methanotrophic symbionts were surveyed using isobaric and unpressurized samples. As a hallmark of cell death, massive DNA fragmentation was observed in methanotrophic symbionts from unpressurized Bathymodiolinae while several endonucleases and restriction enzymes were upregulated. Additionally, genes involved in DNA repair, glucose/methane metabolism as well as two-component regulatory system were also differentially expressed in depressurized symbionts. DNA fragmentation and programmed cell death, however, were rarely detected in the host bacteriocytes owing to the orchestrated upregulation of inhibitor of apoptosis genes and downregulation of caspase genes. Meanwhile, diverse host immune recognition receptors were promoted during depressurization, probably enabling the regain of symbionts. When the holobionts were subjected to a prolonged acclimation at atmospheric pressure, alternations in both the DNA fragmentation and the expression atlas of aforesaid genes were continuously observed in symbionts, demonstrating the persistent influence of depressurization. Contrarily, the host cells demonstrated certain tolerance against depressurization stress as expression level of some immune-related genes returned to the basal level in isobaric samples. Altogether, the present study illustrates the distinct stress responses of Bathymodiolinae hosts and their methanotrophic symbionts against depressurization, which could provide further insight into the deep-sea adaptation of Bathymodiolinae holobionts while highlighting the necessity of using isobaric sampling methods in deep-sea research.Constitutively expressed by innate immune cells, the cytokine macrophage migration inhibitory factor (MIF) initiates host immune responses and drives pathogenic responses in infectious, inflammatory, and autoimmune diseases. Dendritic cells (DCs) express high levels of MIF, but the role of MIF in DC function remains poorly characterized. As migration is critical for DC immune surveillance, we investigated whether MIF promoted the migration of DCs. In classical transwell experiments, MIF-/- bone marrow-derived DCs (BMDCs) or MIF+/+ BMDCs treated with ISO-1, an inhibitor of MIF, showed markedly reduced spontaneous migration and chemotaxis. CD74-/- BMDCs that are deficient in the ligand-binding component of the cognate MIF receptor exhibited a migration defect similar to that of MIF-/- BMDCs. Adoptive transfer experiments of LPS-matured MIF+/+ and MIF-/- and of CD74+/+ and CD74-/- BMDCs injected into the hind footpads of homologous or heterologous mice showed that the autocrine and paracrine MIF activity acting via CD74 contributed to the recruitment of DCs to the draining lymph nodes. Mechanistically, MIF activated the Src/PI3K signaling pathway and myosin II complexes, which were required for the migration of BMDCs. Telaprevir Altogether, these data show that the cytokine MIF exerts chemokine-like activity for DC motility and trafficking.Dysfunction of the lymphatic system is associated with a wide range of disease phenotypes. The restoration of dysfunctional lymphatic vessels has been hypothesized as an innovative method to rescue healthy phenotypes in diseased states including neurological conditions, metabolic syndromes, and cardiovascular disease. Compared to the vascular system, little is known about the molecular regulation that controls lymphatic tube morphogenesis. Using synthetic hyaluronic acid (HA) hydrogels as a chemically and mechanically tunable system to preserve lymphatic endothelial cell (LECs) phenotypes, we demonstrate that low matrix elasticity primes lymphatic cord-like structure (CLS) formation directed by a high concentration of vascular endothelial growth factor-C (VEGF-C). Decreasing the substrate stiffness results in the upregulation of key lymphatic markers, including PROX-1, lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1), and VEGFR-3. Consequently, higher levels of VEGFR-3 enable stimulation of LECs with VEGF-C which is required to both activate matrix metalloproteinases (MMPs) and facilitate LEC migration. Both of these steps are critical in establishing CLS formation in vitro. With decreases in substrate elasticity, we observe increased MMP expression and increased cellular elongation, as well as formation of intracellular vacuoles, which can further merge into coalescent vacuoles. RNAi studies demonstrate that MMP-14 is required to enable CLS formation and that LECs sense matrix stiffness through YAP/TAZ mechanosensors leading to the activation of their downstream target genes. Collectively, we show that by tuning both the matrix stiffness and VEGF-C concentration, the signaling pathways of CLS formation can be regulated in a synthetic matrix, resulting in lymphatic networks which will be useful for the study of lymphatic biology and future approaches in tissue regeneration.
To examine whether frequency, perceived severity and fear of hypoglycaemia are independently associated with diabetes-specific quality of life in adolescents with type 1 diabetes.

Cross-sectional self-reported data on demographics, frequency and perceived severity of both self-treated and severe hypoglycaemia, fear of hypoglycaemia (Hypoglycaemia Fear Survey-Child version) and diabetes-specific quality of life (Pediatric Quality of Life Diabetes Module; PedsQL-DM) were obtained from the project 'Whose diabetes is it anyway?'. Hierarchical regression analyses were performed for the total scale and recommended summary scores of the PedsQL-DM as dependent variables; independent variables were entered in the following steps (1) age, gender and HbA
, (2) frequency of hypoglycaemia, (3) perceived severity of hypoglycaemia and (4) fear of hypoglycaemia.

Adolescents (12-18years; n=96) completed questionnaires. In the first three steps, female gender (p<0.05), higher HbA
(p<0.05), higher frequency of severe hypoglycaemia (p<0.
