Abstract
Background
Metamorphic climax is the crucial stage of amphibian metamorphosis responsible for the morphological and functional changes necessary for transition to a terrestrial habitat. This developmental period is sensitive to environmental changes and pollution. Understanding its metabolic basis and requirements is significant for ecological and toxicological research. Rana omeimontis tadpoles are a useful model for investigating this stage as their liver is involved in both metabolic regulation and fat storage.

Results
We used a combined approach of transcriptomics and metabolomics to study the metabolic reorganization during natural and T3-driven metamorphic climax in the liver and tail of Rana omeimontis tadpoles. The metabolic flux from the apoptotic tail replaced hepatic fat storage as metabolic fuel, resulting in increased hepatic amino acid and fat levels. In the liver, amino acid catabolism (transamination and urea cycle) was upregulated along with energy metabolism (TCA cycle and oxidative phosphorylation), while the carbohydrate and lipid catabolism (glycolysis, pentose phosphate pathway (PPP), and β-oxidation) decreased. The hepatic glycogen phosphorylation and gluconeogenesis were upregulated, and the carbohydrate flux was used for synthesis of glycan units (e.g., UDP-glucuronate). In the tail, glycolysis, β-oxidation, and transamination were all downregulated, accompanied by synchronous downregulation of energy production and consumption. Glycogenolysis was maintained in the tail, and the carbohydrate flux likely flowed into both PPP and the synthesis of glycan units (e.g., UDP-glucuronate and UDP-glucosamine). Fatty acid elongation and desaturation, as well as the synthesis of bioactive lipid (e.g., prostaglandins) were encouraged in the tail during metamorphic climax. Protein synthesis was downregulated in both the liver and tail. The significance of these metabolic adjustments and their potential regulation mechanism are discussed.

Conclusion
The energic strategy and anabolic requirements during metamorphic climax were revealed at the molecular level. Amino acid made an increased contribution to energy metabolism during metamorphic climax. Carbohydrate anabolism was essential for the body construction of the froglets. The tail was critical in anabolism including synthesizing bioactive metabolites. These findings increase our understanding of amphibian metamorphosis and provide background information for ecological, evolutionary, conservation, and developmental studies of amphibians.

Abstract
Background
Dietary fiber can be fermented in gut of pigs and the end products of fermentation were short-chain fatty acids (SCFA). The SCFA had positive effects on gut bacteria and host immune system. In addition, SCFA can provide a part of available energy for pigs. However, there were limited reports on the relationship between dietary fiber, gut bacteria, and energy metabolism. Therefore, this study investigated how dietary fiber and enzyme addition impacted energy metabolism by acting on the microbial community and SCFA.

Methods
Wheat bran (WB) was added to the corn-soybean meal-based diet at the levels of 12% and 27%, and oat bran (OB) at 15% and 36%. One of each diet was supplemented with or without 5000 U/kg feed of xylanase, so a total of 10 diets were allotted to 60 growing pigs (initial body weight: 27.2 ± 1.2 kg) using a randomized complete block design. The experiment was conducted in 10 consecutive periods using 6 similar open-circuit respiration chambers. Each pig was used for one 20-day period. During each period, six pigs were allowed 14 d to adapt to the diets in metabolic cages followed by 6 d (from d 15 to d 20) in respiration chambers to measure heat production (HP).

Results
Pigs fed 36% OB diets had greater (P <  0.05) nutrient digestibility and net energy (NE) values compared to those fed 27% WB diets. Apparent digestibility coefficients of dry matter (DM) and crude protein (CP) were lower (P < 0.05) in pigs fed 27% WB diets compared with those fed 12% WB diets. Enzyme addition improved (P < 0.05) the NE values (11.37 vs. 12.43 MJ/kg DM) in diets with 27% WB. Supplementation of xylanase did not affect NE values for basal diets, OB diets and 12%WB diets. Compared with diets with 36% OB, pigs fed 27% WB-based diets excreted more total SCFA, acetate and propionate (expressed as g/kg feed DM) in fecal samples of pigs (P < 0.05). Pigs in the WB diets had greater proportion of phylum Bacteroidetes while phylum Firmicutes were greater in pigs fed OB diets (P < 0.05). Pigs fed WB diets had greater (P < 0.05) abundance of Succinivibrio and Prevotella, which were associated with fiber degradation and SCFA production.

Conclusion
Our results indicated diets supplied by high level of OB or WB promote the growth of fiber-degrading bacteria. The differences in fiber composition between WB and OB led to differences in nutrient digestibility and bacterial communities, which were ultimately reflected in energy metabolism. Enzyme supplementation improved nutrient digestibility as well as NE values for 27% WB diets but not for other diets, which indicated that effects of enzyme were related to type and level of dietary fiber in diets.

AbstractBackgroundInterest in the interplay between host genetics and the gut microbiome in complex human diseases is increasing, with prior evidence mainly being derived from animal models. In addition, the shared and distinct microbiome features among complex human diseases remain largely unclear.ResultsThis analysis was based on a Chinese population with 1475 participants. We estimated the SNP-based heritability, which suggested thatDesulfovibrionaceaeandOdoribacterhad significant heritability estimates (0.456 and 0.476, respectively). We performed a microbiome genome-wide association study to identify host genetic variants associated with the gut microbiome. We then conducted bidirectional Mendelian randomization analyses to examine the potential causal associations between the gut microbiome and complex human diseases. We found thatSaccharibacteriacould potentially decrease the concentration of serum creatinine and increase the estimated glomerular filtration rate. On the other hand, atrial fibrillation, chronic kidney disease and prostate cancer, as predicted by host genetics, had potential causal effects on the abundance of some specific gut microbiota. For example, atrial fibrillation increased the abundance ofBurkholderialesandAlcaligenaceaeand decreased the abundance ofLachnobacterium,Bacteroides coprophilus,Barnesiellaceae, an undefined genus in the familyVeillonellaceaeandMitsuokella. Further disease-microbiome feature analysis suggested that systemic lupus erythematosus and chronic myeloid leukaemia shared common gut microbiome features.ConclusionsThese results suggest that different complex human diseases share common and distinct gut microbiome features, which may help reshape our understanding of disease aetiology in humans.

Abstract
The small panel of the ‘Crucifixion’ attributed to Giovanni (da Rimini) Baronzio is a perfect example of the artistic achievements of the so-called School of Rimini. Baronzio, active between 1320 and 1350, was one of the most important painters of a group of artists working in Rimini during the first half of the 14th-century whose work was heavily influenced by the work of Giotto di Bondone (1267–1337), characterized by Gothic and Byzantine influences. The panel, with an estimated date in the end of the 1320 s, represents a popular iconographic theme during this period and was painted in tempera and gold on wood. Non-invasive analytical approaches have revealed a rich history of interventions, re-touching and restorations, which allows for some interesting observations and considerations in regard to the work’s history. The applied analytical methods and the related art historical observations and interpretations are the focus of the present article. In order to avoid micro-sampling, a non-invasive methodological approach integrating spectroscopic (μ-X-ray fluorescence spectroscopy, Fourier transform infrared spectroscopy), imaging (UV, X-ray radiography, infrared reflectography) and digital microscopy techniques was applied. This study aimed at the identification of the work’s original materials and techniques, its state of preservation and the complex history of interventions. Results showed that while original materials of the painting conform with those used by artists in fourteenth century Renaissance Italy, there are multiple later interventions both as small-scale inpainting as well as extensive overpainting of various parts of the original Crucifixion composition. Careful consideration of these interventions can shed light to aspects of the panel’s history of preservation as well as on issues of stylistic or compositional ‘corrections’- always an interesting dimension of the changing perceptions of works of art through time.

Abstract
Background
Selective serotonergic reuptake inhibitors (SSRIs) are first-line pharmacologic treatments for patients with posttraumatic stress disorder (PTSD), but must be given over extended period of time before the onset of action. The use of SSRIs in PTSD patients with mild traumatic brain injury (mTBI) is problematic since SSRIs could exacerbate post-concussion syndrome (PCS) symptoms. VA/DOD guidelines identify trauma-focused psychotherapy as the best evidence-based treatment for PTSD, but overall effectiveness is limited by reduced levels of patient engagement and retention. A previous study from this research group suggested that quetiapine monotherapy, but not risperidone or valproate, could increase engagement in trauma-focused psychotherapy.

Methods
We report the study protocol of a pilot study funded under the South-Central Mental Illness Research, Education, and Clinical Center pilot study program from the U.S. Department of Veterans Affairs. This randomized, open-label study was designed to evaluate the feasibility of completing a randomized trial of quetiapine vs. treatment as usual to promote patient engagement in PTSD patients with a history of mTBI.

Discussion
We expect that the success of this ongoing study should provide us with the preliminary data necessary to design a full-scale randomized trial. Positive efficacy results in a full- scale trial should inform new VA guidelines for clinical practice by showing that quetiapine-related improvements in patient engagement and retention may be the most effective approach to assure that VA resources achieve the best possible outcome for veterans.

100 Background: Transitions of care are a frequent focus of quality improvement initiatives. In attempt to improve upon the transitions of care for oncology patients, our institution implemented a post discharge virtual visit follow-up program. Previous studies have suggested that socioeconomic status impacts engagement in technology based interventions. Herein, we report the impact of socio-economic status based on area deprivation index (ADI) on engagement with the program. Methods: All patients admitted to the elective chemotherapy service were included. Retrospective analysis of characteristics of each participant was conducted. Data included eligibility (access to the internet, appropriate device, English language proficiency, ability to set up video visit and a patient portal account) for video visit, interest in participating, completion of the visit and any interventions performed during the visit. In addition, ADI was calculated for each individual. Patients were classified into quartiles based on ADI (quartiles increased with ADI). Chi squared testing was performed to assess whether socioeconomic status affected enrollment in video visits. Simple descriptive analysis was also performed. Results: One hundred seven unique patients were included for review. Of these, 33 (31%), 39 (36%), 16 (15%) and 19 (18%) were in quartile(Q) 1, 2, 3 and 4 respectively. Eligibility per quartile was 29 (88%), 34(87%), 13(81%), and 15(83%). ADI quartile did not significantly affect virtual visit eligibility (p = .50). A total of 91 patients (85%) were eligible for video visits; of these, 46 patients declined. Of the 46 patients that declined 9 (19%), 20 (43%), 8 (17%), and 9 (19%) were in Q1, Q2, Q3 and Q4 respectively. Fifteen patients cited technology issues as reasons for declining telehealth visits - 10 (67%) from Q1 and Q2 and 5 (33%) from Q3 and Q4. The vast majority cited lack of interest as reason for declining. Conclusions: ADI as a measure of socioeconomic status did not significantly affect eligibility for or enrollment in video visits. This may be explained by more ubiquitous access to internet services in a large urban setting. Current research is currently being conducted to understand patient barriers to engagement in virtual visits.

109 Background: Rural cancer care in the United States has unique challenges from variable access to care. This study examined differences in time to first treatment (TTT), a surrogate for access, and predictors of overall survival (OS) between rural and non-rural colorectal cancer (CRC) patients. Methods: Patients with stage I-III CRC from 2004-2012 in the National Cancer Database of Commission on Cancer (CoC)-accredited facilities were included and categorized into rural and non-rural groups. Differences in demographic, disease characteristics, socioeconomic (SE) factors and TTT (< 4 weeks, 4-8 weeks and > 8 weeks) between rural and non-rural patients were assessed by Chi-square test. The effect of demographics, SE factors, and TTT on OS were assessed using Cox models. Results: The study population comprised 605,913, 11,649 (2%) of whom were rural. Compared to non-rural patients, rural patients were more likely to be age > 65, male, Caucasian, receive care at non-academic centers, have government insurance, have lower income and less education (p<0.0001 for all). Significant demographic and SE differences are shown in Table. Rural patients had similar mean TTT compared to non-rural patients (2.76 vs. 2.84 weeks, p = 0.35). Slightly more rural patients had TTT < 4 weeks (77% vs. 75%, p <0.0001). Shorter TTT (both <4 weeks vs. 8 weeks and 4-8 weeks vs. > 8 weeks) was associated with improved OS (HR: 0.87, 95% CI: 0.85-0.89, p<0.0001 and HR: 0.74, 95% CI: 0.73-0.76, p<0.0001, respectively). After adjusting for demographic, disease and SE factors, rural status was associated with modestly better OS compared to non-rural status (HR: 0.96, 95% CI: 0.92-0.99, p=0.006). Conclusions: Despite several adverse demographic and socioeconomic factors, rural CRC patients had modestly better OS compared to non-rural patients. Rural and non-rural CRC patients had similar TTT in this cohort. These data suggest the comprehensive cancer care delivered by CoC-accredited practices is associated with rapid TTT and improved OS in rural CRC patients. It is unclear whether our data apply to non-CoC-accredited facilities in rural United States. [Table: see text]

111 Background: The COVID-19 pandemic poses psychosocial challenges to the oncology workforce. We postulate that these impacts may affect the entire patient-facing workforce. Whether distress is different in varying settings (metro vs regional hospitals) is unknown. Methods: Cancer Care staff were approached via all-staff email for a weekly online survey administered at two hospital sites, Royal Brisbane and Women’s Hospital (RBWH) (metro) and Sunshine Coast Hospital and Health System (SCHHS) (regional). Surveys included Likert-scale items exploring perceptions of departmental preparation, COVID-19 related query burden and staff well-being, and distress thermometer derived from NCCN. Mean and 95% confidence interval were calculated, with non-parametric t-tests adjusted for multiple comparisons (Holm-Sidak); significance was deemed p < 0.05. Results: 117 participants at RBWH and 59 at SCHHS consented. The survey opened April 3, 2020. Data is presented for the initial 6 weeks (COVID-19 preparation phase). Highest survey response was noted in week 1 (87%) and lowest at week 6 (36%). 65% unique responses were from RBWH. 60% participants worked in an outpatient setting, while 37% had inpatient care role. The remainder worked in either community-based or mixed settings. Significant heterogeneity was detected between sites (RBWH vs SCHHS) for some occupational roles: RBWH had more representation of administrative (19% vs 8%, p < 0.001) and ancillary staff (2% vs 0%, p = 0.005) but SCHHS had more allied health (28% vs 17%, p = 0.005). Nursing and medical staff proportions at SCHHS and RBWH were similar (50% vs 45%, and 14% vs 18% respectively). Higher levels of distress were noted early; mean (95% CI) distress thermometer result (0-10) during week 1 was 4.7 (4.3-5.2) at RBWH and 4.9 (4.2-5.5) at SCHHS. Mean distress scores significantly reduced over time: correlative scores during week 6 were 3.2 (2.3-4.1) at RBWH and 2.5 (1.6-3.4) at SCHHS. Distress levels comparing RBWH with SCHHS were similar (p = 0.22-0.76). No significant difference was noted in staff perception of self-support comparing RBWH with SCHHS, and over 80% responders felt well-supported at work most, or all of the time. Concurrently, participants perceived that the Cancer Care department of their site was either “well” or “very well” prepared for COVID-19 over 85% of the time, with no difference between sites. Conclusions: High perceptions of support and preparedness were evident, with no regional difference. Distress scores reduced over time during the COVID-19 preparation phase, in the context of low COVID-19 rates.

115 Background: Indigenous women with breast cancer have substantially higher mortality then non-Indigenous women. They are more likely to live in more remote communities with potential delays to presentation, investigation and diagnosis as well as slower access to cancer treatment facilities, potentially impacting survival. Here we explore by evaluating the diagnosis of de-novo metastasis and any association of remoteness, highlighting the geographic and possibly early access to treatment. Methods: A cohort of patients was retrospectively selected comprising age- and remoteness matched Indigenous and non-Indigenous women in a 1:1 ratio from the Western Australian Cancer Registry. Further data were collected from medical records and results systems. Remoteness was defined by the ARIA system. In addition, the distance from the nearest treatment center was calculated. The survival analysis was performed by Indigenous status and remoteness. Results: The final cohort comprised 250 Indigenous and 261 non–Indigenous women. Of the total, 7.6% (19/250) and 7.7% (20/261) were identified to have de-novo metastasis. At 10 years of follow up, most de-novo metastatic patients in both groups were from remote communities, distributed as 10.1, 9.1, 7.8, 8.7 and 5.0 % in metropolitan, inner regional, outer regional, remote and very remote areas respectively. In Indigenous group with de-novo metastasis the average distance of patient from treatment center was 1720km for vs 1018 km in Non-Indigenous patient with a p-value of 0.03. In non-metastasis cohort, Indigenous patient has 1065 km v 1241 km in non-indigenous group. Considering outcomes for those developing metastatic disease, median survivals after metastatic diagnosis were shorter for Indigenous patients, 21 v 33 months, p = 0.03. Conclusions: Indigenous women in WA with metastatic breast cancer have inferior survival outcomes from diagnosis of metastases relative to non-Indigenous peers. Most de-novo metastatic patients were from remote locations in both cohorts but no relation between remoteness and de-novo metastasis, identified to be impacting survival. Future studies are needed to better elucidate if any geographical, health care disparities and improve on treatment related outcomes. It is suggested to derive targeted policies to improve survival outcome of all Indigenous cancer patients, particularly those residing in remote areas.
