Abstract
Adult stem cells maintain regenerative tissue structure and function by producing tissue-specific progeny, but the factors that preserve their tissue identities are not well understood. The small and large intestines differ markedly in cell composition and function, reflecting their distinct stem cell populations. Here we show that SATB2, a colon-restricted chromatin factor, singularly preserves LGR5+ adult colonic stem cell and epithelial identity in mice and humans. Satb2 loss in adult mice leads to stable conversion of colonic stem cells into small intestine ileal-like stem cells and replacement of the colonic mucosa with one that resembles the ileum. Conversely, SATB2 confers colonic properties on the mouse ileum. Human colonic organoids also adopt ileal characteristics upon SATB2 loss. SATB2 regulates colonic identity in part by modulating enhancer binding of the intestinal transcription factors CDX2 and HNF4A. Our study uncovers a conserved core regulator of colonic stem cells able to mediate cross-tissue plasticity in mature intestines.

Abstract
Abstract
Background
Myocardial injury after noncardiac surgery (MINS) is common and is associated with postoperative major cardiac events and 30-day mortality. We have previously established the diagnostic criteria for MINS with the 4th-generation cardiac troponin T assay (TnT) and 5th-generation high-sensitivity TnT assay (hsTnT) based on prognostically relevant thresholds. Little is known about diagnostic criteria for MINS using the high-sensitivity troponin I (hsTnI) assay.
Purpose
To determine hsTnI thresholds associated with 30-day major cardiac events and death after noncardiac surgery.
Methods
We performed a nested prospective biobank cohort study of 4545 patients from the VISION Study. Patients were aged ≥45 years and underwent in-patient noncardiac surgery under regional or general anesthesia. Patients had samples collected and frozen preoperatively, and on postoperative days 1, 2 and 3. We measured hsTnI on thawed preoperative and postoperative samples. We used iterative Cox proportional hazard models to determine peak postoperative hsTnI thresholds independently associated with major cardiac events (i.e., composite of death, non-fatal cardiac arrest, congestive heart failure within 30 days and non-fatal myocardial infarction from postoperative days 4–30).
Results
Major cardiac events occurred in 89/4545 (2.0%) patients. Peak hsTnI values of <75 ng/L, 75 ng/L to <1000 ng/L, and ≥1000 ng/L were associated with an incidence of major cardiac events of 1.2% (95% CI 0.9–1.6), 7.1% (95% CI 4.8–10.5) and 25.9% (95% CI 16.3–38.4), respectively. Compared to peak hsTnI <75 ng/L (reference), hsTnI values 75 ng/L to <1000 ng/L and ≥1000 ng/L were associated with adjusted hazard ratios (aHR) of 4.53 (95% CI 2.75–7.48) and 16.17 (95% CI 8.70–30.07), respectively. No change from preoperative hsTnI to peak postoperative hsTnI significantly improved the model when included on top of the identified thresholds. Incidence of major cardiac events was 31/343 (9%) in patients with postoperative peak hsTnI ≥75 ng/L versus 52/4178 (1%) in patients with postoperative peak hsTnI <75 ng/L (aHR 5.76; 95% CI 3.64–9.11). A postoperative peak hsTnI ≥75 ng/L was associated with increased risk of major cardiac events either in the presence (aHR 9.35; 95% CI 5.28–16.55) or absence (aHR 3.99; 95% CI 2.19–7.25) of clinical features of myocardial injury (e.g., chest pain, ischemic electrocardiography changes).
Conclusion
A hsTnI elevation within the first 3 days after noncardiac surgery independently predicts major cardiac events at 30 days. A peak postoperative hsTnI ≥75 ng/L was associated with a 6-fold increase in the risk of subsequent major cardiac events at 30 days as compared to peak postoperative hsTnI<75 ng/L. This hsTnI threshold can be used to diagnose MINS.

Abstract
AIM To evaluate the association between the image quality of cancer staging whole-body magnetic resonance imaging (WB-MRI) and patient demographics, distress, and perceived scan burden. MATERIALS AND METHODS A sample of patients recruited prospectively to multicentre trials comparing WB-MRI with standard scans for staging lung and colorectal cancer were invited to complete two questionnaires. The baseline questionnaire, administered at recruitment, collated data on demographics, distress and co-morbidity. The follow-up questionnaire, completed after staging investigations, measured perceived WB-MRI scan burden (scored 1 low to 7 high). WB-MRI anatomical coverage, and technical quality was graded by a radiographic technician and grading combined to categorise the scan as "optimal", "sub-optimal" or "degraded". A radiologist categorised 30 scans to test interobserver agreement. Data were analysed using the chi-square, Fisher's exact, t-tests, and multinomial regression. RESULTS One hundred and fourteen patients were included in the study (53 lung, 61 colorectal; average age 65.3 years, SD=11.8; 66 men [57.9%]). Overall, 45.6% (n=52), scans were classified as "optimal" quality, 39.5% (n=45) "sub-optimal", and 14.9% (n=17) as "degraded". In adjusted analyses, greater deprivation level and higher patient-reported scan burden were both associated with a higher likelihood of having a sub-optimal versus an optimal scan (odds ratio [OR]: 4.465, 95% confidence interval [CI]: 1.454 to 13.709, p=0.009; OR: 1.987, CI: 1.153 to 3.425, p=0.013, respectively). None of the variables predicted the likelihood of having a degraded scan. CONCLUSIONS Deprivation and patients' perceived experience of the WB-MRI are related to image quality. Tailored protocols and individualised patient management before and during WB-MRI may improve image quality.

Abstract
BACKGROUND The pathology of eosinophilic esophagitis (EoE) is characterized by eosinophil-rich inflammation, basal zone hyperplasia (BZH), and dilated intercellular spaces, and the underlying processes that drive the pathologic manifestations of the disease remain largely unexplored. OBJECTIVE We sought to investigate the involvement of the calcium-activated chloride channel anoctamin 1 (ANO1) in esophageal proliferation and the histopathologic features of EoE. METHODS We examined mRNA and protein expression of ANO1 in esophageal biopsy samples from patients with EoE and in mice with EoE. We performed molecular and cellular analyses and ion transport assays on an in vitro esophageal epithelial 3-dimensional model system (EPC2-ALI) and murine models of EoE to define the relationship between expression and function of ANO1 and esophageal epithelial proliferation in patients with EoE. RESULTS We observed increased ANO1 expression in esophageal biopsy samples from patients with EoE and in mice with EoE. ANO1 was expressed within the esophageal basal zone, and expression correlated positively with disease severity (eosinophils/high-power field) and BZH. Using an in vitro esophageal epithelial 3-dimensional model system revealed that ANO1 undergoes chromatin modification and rapid upregulation of expression after IL-13 stimulation, that ANO1 is the primary apical IL-13-induced Cl- transport mechanism within the esophageal epithelium, and that loss of ANO1-dependent Cl- transport abrogated esophageal epithelial proliferation. Mechanistically, ANO1-dependent regulation of basal cell proliferation was associated with modulation of TP63 expression and phosphorylated cyclin-dependent kinase 2 levels. CONCLUSIONS These data identify a functional role for ANO1 in esophageal cell proliferation and BZH in patients with EoE and provide a rationale for pharmacologic intervention of ANO1 function in patients with EoE.

Abstract
Abstract
Background
Steroid refractory acute graft- vs. -host-disease (GVHD) after hematopoietic cell transplantation (HCT) is highly morbid with limited treatment options. Murine studies show protection from GVHD with butyrate exposure but direct exposure of stem/progenitor cells to butyrate inhibits colonic stem cell proliferation.
Methods
Stool samples were collected weekly in a cohort of HCT recipients (n = 210) undergoing allogeneic transplant, and underwent 16S rRNA sequencing to determine the number and relative abundance of butyrogens. Dissociated primary human colonoid cell aggregates (200,000 per well) were plated onto collagen IV-coated transwells (0.4 µm pore size, 0.33 cm2, PET) in stem cell medium for 24 hours. From 24 hours onwards, the basal-lateral chamber was switched to differentiation medium; the apical chamber was Hanks Buffered Salt Solution (HBSS), HBSS with 10 mM butyrate sodium salt early (24 hours onwards) or late (72hours onwards). Trans-epithelial electrical resistance was measured daily.
Results
Retrospective chart review identified 27 recipients who developed acute GVHD of the gut, stratified to be either steroid refractory GVHD (failed to respond to 2 mg/kg of methylprednisolone) or responsive. The presence of butyrogens in the gut microbiome after the onset of severe acute GHVD of the gut associated with increased risk of steroid refractory GVHD (Figure 1; P < 0.05). Direct exposure of human colonic stem/progenitor cells to butyrate inhibits the development of trans-epithelial electrical resistance; exposure after differentiation had no inhibition of barrier formation (Figure 2; P < 0.05 by T-test).
Conclusion
Butyrogens may help prevent the development of acute GVHD of the gut, but once severe GVHD has developed may inhibit recovery due to the loss of crypt architecture exposing colonic stem cells to microbe-produced butyrate with impaired differentiation and cell replacement.

Abstract
The presence of butyrogenic bacteria after the onset of acute GVHD associates with subsequent steroid-refractory GVHD or chronic GVHD. Butyrate inhibits human colonic stem cells from forming an intact epithelial monolayer.

Abstract
BACKGROUND Atrial fibrillation (AF) is often detected for the first time in patients hospitalized for medical illness or non-cardiovascular surgery. AF occurring transiently with stress (AFOTS) describes this manifestation of AF, which may either be the result of a non-cardiac stressor, or existing paroxysmal AF that was not previously detected. Current estimates of AFOTS incidence are imprecise: ranging from 1 to 44%, owing to the marked heterogeneity in patient populations, identification and methods used to detect AFOTS. METHODS The prospective, two-centre epidemiological AFOTS Incidence study will enroll 250 consecutive participants without a history of AF but with at increased risk of AF (Age ≥ 65 or >50 with one risk factor for AF) admitted to intensive care units (ICUs) for medical illness or non-cardiac surgery. Upon admission, participants will wear an ECG patch monitor that will remain in place for 14 days, or until discharge from hospital. Patients' consent to participation is deferred for up to 72 h after admission. The primary endpoint is the incidence of AF lasting ≥30 s. The study is powered to detect an AF incidence of 17% ± 5%. RESULTS We conducted a vanguard feasibility study, and 55 participants have completed participation. The median duration of monitoring was seven days. AF was detected by the clinical team in 8 participants (14%; 95% Confidence Interval 7-26%). CONCLUSIONS The AFOTS Incidence study will employ a systematic and highly sensitive protocol for detecting AFOTS in medical illness and non-cardiac surgery ICU patients. This study is feasible and will provide a reliable estimate of the true incidence of AFOTS in this population.

Abstract
The aim was to evaluate the efficacy and safety of volatile anaesthetic for postoperative sedation in adult cardiac surgery patients through a systematic review and meta-analysis. We retrieved randomized controlled trials from MEDLINE, EMBASE, CENTRAL, Web of Science, clinical trials registries, conference proceedings, and reference lists of included articles. Independent reviewers extracted data, including patient characteristics, type of intraoperative anaesthesia, inhaled anaesthetic used, comparator sedation, and outcomes of interest, using pre-piloted forms. We assessed risk of bias using the Cochrane Tool and evaluated the strength of the evidence using the GRADE approach. Eight studies enrolling 610 patients were included. Seven had a high and one a low risk of bias. The times to extubation after intensive care unit (ICU) admission and sedation discontinuation were, respectively, 76 [95% confidence interval (CI) -150 to - 2, I2=79%] and 74 min (95% CI - 126 to - 23, I2=96%) less in patients who were sedated using volatile anaesthetic. There was no difference in ICU or hospital length of stay. Patients who received volatile anaesthetic sedation had troponin concentrations that were 0.71 ng ml-1 (95% CI 0.23-1.2) lower than control patients. Reporting on other outcomes was varied and not suitable for meta-analysis. Volatile anaesthetic sedation may be associated with a shorter time to extubation after cardiac surgery but no change in ICU or hospital length of stay. It is associated with a significantly lower postoperative troponin concentration, but the impact of this on adverse cardiovascular outcomes is uncertain. Blinded randomized trials using intention-to-treat analysis are required. PROSPERO registry number: 2016:CRD42016033874.

Abstract
Background and context: The Bridge of Support Program (BOS) is adapting a successful community based model of peer support to an acute setting, at the Sunshine Hospital Breast Clinic, to meet the cultural and socioeconomic diverse needs of women with breast cancer. This two year project was funded by LUCRF Community Partnership Trust. Aim: To improve the experience of women undergoing treatment of breast cancer at Western Health. To improve access to psych-social, emotional and practical support for women by extending the reach of CounterPart- a state-wide service of women´s Health Victoria, funded by the Victorian Department of Health and Human Services to provide peer support and information to people affected by breast or a gynecologic cancer. Program/Policy process: Peer support volunteers actively guided women to current and credible evidence-based information, support decision making and provide emotional support. Peer support volunteers are rostered once a week at Sunshine Hospital to coincide with breast clinic and include access to the day oncology unit and radiotherapy center. Detailed contact information is recorded and women receive follow-up contact (with consent) from the peer support volunteers at the CounterPart Resource Centre in Melbourne. A CounterPart staff member oversees the project and provides direct support and supervision to the volunteers on site at the hospital. Women can self refer. Outcomes: Between February and December 2016 the BOS program had 159 separate contacts with patients and their families. 82 contacts were with men and women who were new to CounterPart and 77 were follow-up contacts. 90 individuals treated for breast cancer at Western Health accessed the program, which represent 53% of the women seen by the breast service. 48% of the contacts were follow-up contacts with the CounterPart volunteers indicating that once engaged with the service many men and women continue to make contact. 38% of contacts were with women diagnosed with metastatic disease, a group who often have higher levels of unmet or more complex needs. 49% were born in a nonmain English speaking country (compared with the overall state of Victoria average of 19.6%) thus reflecting an accessible service to the non-English speaking community. What was learned: At a time when peer support is being increasingly recognized as a key part of effective supportive care in cancer services, the BOS program offers a model of integrated peer support that is respected, reliable, well supported and safe within the acute setting. This acute-community sector partnership demonstrates how the medical and social models of health care can work together to provide a connected and quality service for men and women diagnosed with breast cancer. An active research approach is enabling the project to be responsive to issues and challenges as they arise including the ongoing recruitment of women as volunteers from the local community to work within the acute setting.

Abstract
The neurohormone oxytocin plays a central role in human social behaviour and cognition, and oxytocin dysregulation may contribute to psychiatric disorders. However, genetic factors influencing individual variation in the oxytocinergic system remain poorly understood. We genotyped 169 healthy adults for a functional polymorphism in GTF2I (general transcription factor II-I), a gene associated with high prosociality and reduced social anxiety in Williams syndrome, a condition reported to involve high oxytocin levels and reactivity. Participants' salivary oxytocin levels were measured before and after watching a validated empathy-inducing video. Oxytocin reactivity, defined as pre- to post-video percentage change in salivary oxytocin, varied substantially and significantly between individuals with different GTF2I genotypes, with, additionally, a trend towards an interaction between genotype and sex. Individuals with more oxytocin-reactive genotypes also reported significantly lower social anxiety. These findings suggest a model whereby GTF2I has a continuum of effects on human sociality, from the extreme social phenotypes and oxytocin dysregulation associated with gene deletion in Williams syndrome, to individual differences in oxytocin reactivity and sociality associated with common polymorphisms in healthy populations.

Abstract
In response to injury, epithelial cells migrate and proliferate to cover denuded mucosal surfaces and repair the barrier defect. This process is orchestrated by dynamic crosstalk between immune cells and the epithelium; however, the mechanisms involved remain incompletely understood. Here, we report that IL-10 was rapidly induced following intestinal mucosal injury and was required for optimal intestinal mucosal wound closure. Conditional deletion of IL-10 specifically in CD11c-expressing cells in vivo implicated macrophages as a critical innate immune contributor to IL-10-induced wound closure. Consistent with these findings, wound closure in T cell- and B cell-deficient Rag1-/- mice was unimpaired, demonstrating that adaptive immune cells are not absolutely required for this process. Further, following mucosal injury, macrophage-derived IL-10 resulted in epithelial cAMP response element-binding protein (CREB) activation and subsequent synthesis and secretion of the pro-repair WNT1-inducible signaling protein 1 (WISP-1). WISP-1 induced epithelial cell proliferation and wound closure by activating epithelial pro-proliferative pathways. These findings define the involvement of macrophages in regulating an IL-10/CREB/WISP-1 signaling axis, with broad implications in linking innate immune activation to mucosal wound repair.

Abstract
Abstract
Introduction Characterized enteroid cultures of human colon cancer can more precisely model the diversity of colonic neoplasia for the study of cancer initiation, progression and potentially prevention. Using tissue from colon resections and endoscopic biopsies, we have successfully isolated and cultured 14 colorectal adenomas and 2 adenocarcinomas to date. We have maintained these enteroid cultures for up to 2 years and established a working cryorepository. Specific epithelial cell lineage markers and the stem cell marker Lgr5 can be detected throughout the culture period.
Methods Enteroid cultures have been initiated and maintained in a serum-free medium containing EGF and pituitary extract. However, approximately half of all neoplasms do not establish in this reduced medium. In contrast, most neoplasms develop and expand in an enriched culture medium containing serum, Wnt, R-spondin, Noggin, and EGF. We have also created a mouse xenograft from an adenoma expanded in the reduced media; this graft was then successfully reintroduced into culture. Using whole exome sequencing, we are investigating how the genetic background of individual patients contributes to 1) variability in the establishment and expansion of enteroid cultures 2) tumor heterogeneity in neoplasms and xenografts, and 3) the stability of genomic signatures in enteroids over time in culture.
Results Twenty-two damaging somatic variants identified in a single colon tumor were preserved in enteroid culture after 2 months in reduced medium. Variants included a frameshift mutation in APC and missense mutations in KRAS and TP53. The allele frequency of most variants increased in enteroid culture, suggesting that cells lacking these mutations failed to propagate (including stromal/immune cells), or cells carrying these mutations expanded at a faster rate. Ten mutations not present in the original tumor were acquired over time in enteroid culture. These mutations included a missense variant of TRPS1, a putative prognosticator of colon cancer. The mutations acquired in enteroid culture may reflect genetic instability in the source neoplastic tissue, or the emergence of subpopulations that were below level of detection in the source tissue. Three mutations were present in the tumor and lost in enteroid culture; this presumably reflects the loss of a subset of cells expressing these variants.
Conclusion Changes in allele frequencies suggest that neoplasms are heterogeneous, with shifting cell populations that are differentially affected by culture conditions. This heterogeneity can be further interrogated by comparing allele frequencies in the original tumor with those in enteroids established in reduced or enriched media. This platform can provide further understanding of genetic determinants that underlie the risk for colorectal cancer, as well as strategic insights into the enteroid model as a sophisticated system for the study of tumor biology.

Abstract
Current hard X-ray free-electron laser (XFEL) sources can deliver doses to biological macromolecules well exceeding 1 GGy, in timescales of a few tens of femtoseconds. During the pulse, photoionization can reach the point of saturation in which certain atomic species in the sample lose most of their electrons. This electronic radiation damage causes the atomic scattering factors to change, affecting, in particular, the heavy atoms, due to their higher photoabsorption cross sections. Here, it is shown that experimental serial femtosecond crystallography data collected with an extremely bright XFEL source exhibit a reduction of the effective scattering power of the sulfur atoms in a native protein. Quantitative methods are developed to retrieve information on the effective ionization of the damaged atomic species from experimental data, and the implications of utilizing new phasing methods which can take advantage of this localized radiation damage are discussed.

Abstract
ABSTRACTThe management of febrile pediatric patients is challenging, and the literature is replete with articles describing diverse diagnostic and therapeutic strategies. As many as 5% of infants and young children presenting with fever will be diagnosed with urinary tract infection. Many controversies exist concerning the management of these infections, the most important being: how to make the diagnosis. The financial and time costs of emergency department management must be balanced against the potential future costs of investigations and complications.

Abstract
The overwhelming majority of farmed fish produced throughout the world are killed with little or no consideration for their welfare. Fasting periods can be excessive, transport stressful and killing inhumane. At the time of writing, the salmon industry is the only sector in which consideration of the welfare of the fish at slaughter has resulted in significant improvements throughout most of the industry. There are signs of interest in the use of more humane slaughter methods for some other fish species. This is mostly initiated by the demand for higher standards from European fish retailers. For most species, the humane killing options are limited to percussive stunning and electrical stunning. However, even these methods can have a poor welfare outcome if insufficient consideration is given to the needs of the fish or if the equipment has not been properly designed. The use of food-grade anaesthetics to assist with the harvest has significant potential for improving welfare and their wider use should be investigated further.

Abstract
BACKGROUND & AIMS Metaplasias often have characteristics of developmentally related tissues. Pancreatic metaplastic ducts are usually associated with pancreatitis and pancreatic ductal adenocarcinoma. The tuft cell is a chemosensory cell that responds to signals in the extracellular environment via effector molecules. Commonly found in the biliary tract, tuft cells are absent from normal murine pancreas. Using the aberrant appearance of tuft cells as an indicator, we tested if pancreatic metaplasia represents transdifferentiation to a biliary phenotype and what effect this has on pancreatic tumorigenesis. METHODS We analyzed pancreatic tissue and tumors that developed in mice that express an activated form of Kras (Kras(LSL-G12D/+);Ptf1a(Cre/+) mice). Normal bile duct, pancreatic duct, and tumor-associated metaplasias from the mice were analyzed for tuft cell and biliary progenitor markers, including SOX17, a transcription factor that regulates biliary development. We also analyzed pancreatic tissues from mice expressing transgenic SOX17 alone (ROSA(tTa/+);Ptf1(CreERTM/+);tetO-SOX17) or along with activated Kras (ROSAtT(a/+);Ptf1a(CreERTM/+);tetO-SOX17;Kras(LSL-G12D;+)). RESULTS Tuft cells were frequently found in areas of pancreatic metaplasia, decreased throughout tumor progression, and absent from invasive tumors. Analysis of the pancreatobiliary ductal systems of mice revealed tuft cells in the biliary tract but not the normal pancreatic duct. Analysis for biliary markers revealed expression of SOX17 in pancreatic metaplasia and tumors. Pancreas-specific overexpression of SOX17 led to ductal metaplasia along with inflammation and collagen deposition. Mice that overexpressed SOX17 along with Kras(G12D) had a greater degree of transformed tissue compared with mice expressing only Kras(G12D). Immunofluorescence analysis of human pancreatic tissue arrays revealed the presence of tuft cells in metaplasia and early-stage tumors, along with SOX17 expression, consistent with a biliary phenotype. CONCLUSIONS Expression of Kras(G12D) and SOX17 in mice induces development of metaplasias with a biliary phenotype containing tuft cells. Tuft cells express a number of tumorigenic factors that can alter the microenvironment. Expression of SOX17 induces pancreatitis and promotes Kras(G12D)-induced tumorigenesis in mice.

Abstract
Fish welfare at harvest is easily compromised by poor choice of handling and slaughter methods, lack of attention to detail and by unnecessary adherence to fish farming traditions. The harvest process comprises fasting the fish to empty the gut, crowding the fish, gathering and moving the fish using brails, fish pumps, and sometimes also road or boat transport and finally stunning and killing the fish. The harvesting processes commonly used for bass, bream, carp, catfish, cod, eel, halibut, pangasius, salmon, tilapia, trout, tuna and turbot are outlined. These harvesting processes are discussed; the consequences for fish welfare identified and practical tests which can be made at the harvest site highlighted. Welfare at harvest for the majority of farmed fish species can be improved by adopting and adapting existing procedures already known to be beneficial for fish welfare through their use in other fish farming systems or with other species. It is seldom necessary to develop completely new concepts or methods.
