Critical Race Pedagogy for More Effective and Inclusive World Language Teaching
Authors: Anya Uju 
Published: October 2021

AbstractTo address racial inequity and the exclusion of African Americans in applied linguistics, second-language acquisition, and world language (WL) education, our field must reckon with social justice problems of racism and anti-Blackness. Theoretical frameworks of critical race theory (CRT) and critical race pedagogy (CRP) elucidate how such injustices are perpetuated, plus, propose solutions for them. This article discusses racism and anti-Blackness in WL curriculum, materials, and instructional practices. It presents a post-hoc CRT analysis of findings from two studies: (i) an ethnographic study examining Spanish curriculum and instructional practices at two minority serving postsecondary institutions and (ii) a participatory action research collaboration with Spanish instructors examining curriculum at a predominantly white institution—both studies linked by how they reveal endemic racism and anti-Blackness in WL programmes. Ultimately, this article addresses how African Americans can more authentically and successfully participate in WL programmes. It introduces to the field a proposal of CRP for more effective WL teaching to promote practices in antiracism, equity-mindedness, and inclusivity for greater retention and success of Black students.
1703 The Walking Thread – What Happens to Fistula-In-Ano Patients Who Are Lost to Follow Up? A Service Improvement Study
Authors: Ellen M , Wilson B , Anderson D 
Published: October 2021

Abstract

Aim
1/3 of idiopathic cryptoglandular abscesses can result in fistula-in-ano. Current practice is to incise and drain primary abscesses and safety net for patients to return as necessary. Known fistula patients will be appointed for Examination Under Anaesthetic at 6-12 weeks.Is this best management or do they become “elective emergencies”?

Method
We performed a retrospective audit of management of fistula-in-ano over 4 years. We used a precollected data set of Cryptoglandular abscesses, excluding inflammatory, radiation or malignant causes and collected data for patients lost to follow up, including presentation, fistula diagnosed at first or subsequent attendance, number of operations, number of attendances and seton placement.

Results
512 patients were operated on for cryptoglandular abscess causing fistula-in-ano between 2013 and 2017. 10% (N = 50) were lost to follow up. 32 had documented follow up plans, that were not fulfilled (eg elective theatre not booked). Of these, 18 were elective attendances, 14 emergency. 24 of the 32 had a Seton sited prior to being lost to follow up

Conclusions
The various presentations (emergency, elective, clinic or day surgery) and long waiting lists mean many of these patients are presenting as emergencies still awaiting follow up. Many are lost to follow-up, with Setons in situ. We propose a fortnightly hot-clinic system, registrar led to assess and manage these patients. This would provide an elective clinic to allow single point of access to fistula-in-ano patients ensuring prompt follow up and reduction in unnecessary EUA, as well as improving senior colorectal trainees exposure to perianal disease and its management.
10 COVID-19 and Changing Perceptions Towards Postgraduate Surgical Training in United Kingdom
Authors: Golsharifi M , Hamidi A 
Published: October 2021

Abstract

Aim
The evolution of the current coronavirus disease-2019 (COVID-19) pandemic continues to impact global healthcare systems on an unprecedented scale. Here, we use data from a local NHS trust within the United Kingdom (UK) to examine the perception of medical students and foundation doctors towards postgraduate surgical training.

Method
This tri-centric cross-sectional study was carried out via a survey disseminated within the East Sussex Healthcare NHS trust, King’s College Hospital, and King’s College London Medical School. The survey was active for 14 days (from 15th March 2020 to 28th March 2020), comprising a total of 40 foundation doctors and 10 medical students.

Results
A total of 50 responses were received across five hospitals and their associated medical school. A decrease of 10% and 25% was observed in interest to pursue surgery in medical students and foundation doctors, respectively, following the outbreak of COVID-19. Over 40% of foundation doctors holding postgraduate surgical training offers were not accepting them, and of those, over 40% would not consider reapplying to surgery. There was a drop in interest across a select set of specialities, and this was more obvious where aerosol-generating-procedures was a common occurrence.

Conclusions
These results highlight the need for a more efficient and effective response to address the immediate situation, as well as a robust contingency plan to avert the repercussions the surgical field could face.
101 Paediatric Burns and The Coronavirus Pandemic: Were Children Staying Safe in Lockdown or Did The Virus Increase Burns Admissions?
Authors: Noshirwani A , Raraty C 
Published: October 2021

Abstract

Aim
We aimed to identify if there was a change in the number of paediatric burns during the coronavirus pandemic and whether there was a change in the management of said burns.

Method
Data on ten parameters for all burns assessed on the Burns Unit at Alder Hey Children’s Hospital from April to May of 2020 was collected and compared to the same period from 2019.

Results
There was a decrease in the number of patients presenting to hospital, down to 24 from 32 in 2019. Scald injuries increased to 67% compared to 44%, while all other mechanisms of injuries decreased. Fewer very small burns (&lt;1% TBSA) presented to hospital (28%) compared to 50% the previous year. There was an overall increase in the presentation of burns greater than 1% TBSA (1-5% TBSA increased to 47% from 31%; 5-10% TBSA increased to 19% from 3%; 10-20% TBSA increased to 6% from 3%). A comparable rate of burns was managed conservatively as an outpatient (89% vs 88%), admitted for dressing changes (81% vs 78%), and managed surgically (11% vs 13%).

Conclusions
The coronavirus pandemic resulted in a decrease in the number of children experiencing burns, while at the same time causing an increase in the number of scald injuries. Our data showed no significant change in the management of burns indicating that regardless of the pandemic, paediatric burns were managed appropriately as per national guidelines.

Abstract

Background
Knowledge about how older adults get a respiratory infection is crucial for planning preventive strategies. We aimed to determine how contact with young children living outside of the household affects the risk of acute respiratory tract infections (ARTI) in community-dwelling older adults.

Methods
This study is part of the European RESCEU older adult study. Weekly surveillance was performed to detect ARTI throughout 2 winter seasons (2017-2018, 2018-2019). Child exposure, defined as having regular contact with children under 5 living outside of the subject’s household, was assessed at baseline. The average attributable fraction was calculated to determine the fraction of ARTI explained by exposure to these children.

Results
We prospectively established that 597/1006 (59%) participants experienced at least 1 ARTI. Child exposure increased the risk of all-cause ARTI (adjusted odds ratio [aOR], 1.58; 95% confidence interval [CI], 1.21 -2.08; P = .001). This risk was highest in those with the most frequent contact (aOR, 1.80; 95% CI, 1.23-2.63; P = .003). The average attributable fraction of child exposure explaining ARTI was 10% (95% CI, 5%-15%).

Conclusions
One of 10 ARTI in community-dwelling older adults is attributable to exposure to preschool children living outside of the household.

PSII-15 Investigations of feeding preferences for common palatants in equine weanlings
Authors: Crowell Cierra N , Perry Erin B 
Published: October 2021

Abstract
Work in other species has demonstrated an impact of gestational exposure on flavor preferences. Although equine palatability preferences in mature horses have been identified, feeding behaviors in growing horses are not well documented. The objective of this study was to evaluate the impact of exposure to common palatants in utero on feeding preferences of weanlings. Stock-type weanlings (n = 4) weighing 225(±18.15) kg at 29(±2.55) weeks of age were used in a side-by-side comparison test with a divided feeding platform. Common palatants (apple and anise) were utilized throughout the broodmare gestational period. A novel palatant, peppermint, was withheld during gestation to identify impacts associated with neophobic tendencies. Treatments were offered once daily for three consecutive days across three periods (4 weeks apart) using a pelleted concentrate feed with an application rate of 0.375 mL/0.23 kg. Weanlings were allowed free access to the feeding platform with identical pans spaced 6” apart for 20 minutes. Treatment location within the feeding platform was changed daily to limit effects associated with side-eating. Data were measured as a Chi Square test of SAS using PROC FREQ statement with α ≤. 0.05. Despite gestational exposure to apple and anise, no preference was measured in palatability assessments including First Sniff (P = 0.29), First Consumed (P = 0.70), First Finished (P = 0.29). These data suggest that exposure in utero failed to elicit a preference for common palatants in weanling horses. Additionally, these data fail to demonstrate a neophobic effect for a novel palatant, peppermint.

Published: October 2021

Abstract
We aimed to compare the abundance of interferon-tau stimulated genes (ISG) transcripts in peripheral blood leukocytes of artificially inseminated beef cows using real-time quantitative PCR (RT-qPCR) versus Droplet Digital PCR (ddPCR). Multiparous Bos taurus beef cows (n = 7) were subjected to timed artificial insemination (TAI) on day 0. Pregnancy was determined by transrectal ultrasonography on days 26 and 30 post-TAI, and cows were classified as: pregnant (n=4; embryo detected on days 26 and 30) or non-pregnant (n = 3; no embryo detected). Coccygeal vein blood samples were collected on days 0, 15, 17, 19, 20 and 24 post-TAI. Leukocyte RNA was extracted from the buffy coat fraction using Trizol associated with the DirectZol-RNA kit and transcribed to cDNA. The abundance of ISG (ISG15 and MX2) was assessed by relative quantification to a reference gene (RPS9) using RT-qPCR and by absolute quantification using the QX100TM Droplet DigitalTM PCR System (Bio-rad Laboratories) according to manufacturer’s recommendations. Data were analyzed using PROC MIXED on SAS 9.4. For the RT-qPCR, pregnant cows had greater (P &lt; 0.05) ISG15 and MX2 abundance compared to non-pregnant cows on days 20 (ISG15:0.11±0.1 vs. 0.01±0.001 and MX2:0.73±0.4 vs. 0.06±0.06) and 24 (ISG15:0.34±0.2 vs. 0.01±0.001 and MX2:0.77±0.2 vs. 0.13±0.04). For ddPCR, a greater ISG15 and MX2 copy numbers in pregnant cows was observed on days 15 (ISG15:129 vs. 44 copies/µl and MX2:33 vs. 10 copies/µl) and 20 (ISG15: 216 vs. 30 copies/µl and MX2: 44 vs. 7 copies/µl), and also on day 24 for ISG15 (32 vs. 7 copies/µl) compared to non-pregnant cows. In conclusion, ddPCR was able to detect an earlier expression of ISG in pregnant cows. Future studies are needed to enroll more animals and establish a suitable cutoff value using ddPCR, which could be less subjective for diagnosis as it does not require the use of a reference gene.
PSV-B-20 Effects of Saccharomyces Cerevisiae Fermentation Product (SCFP) postbiotic in labrador retrievers during exercise and transport stress
Authors: Varney Jessica L , Coon Craig N , Norton Sharon A 
Published: October 2021

Abstract
Saccharomyces cerevisiae fermentation product (SCFP) is a dietary postbiotic compound shown to support digestive health and immune function in several species. Two studies were performed to evaluate the effects of SCFP (Diamond V Mills, Inc.; Cedar Rapids, IA) in canines exposed to exercise and transport stress. In both studies, 36 Labrador Retrievers (18 males/18 females) &gt;5y were used. Study 1 consisted of a 3-wk adaptation period followed by a 14-wk series of distance-defined running exercise regimens (DDER) with subjects randomly allocated to three groups of 0 mg/d SCFP, 250 mg/d SCFP, or 500 mg/d SCFP. Study 2 consisted of a 3-wk adaptation period followed by an 8 wk phase of DDER and a final, single transport stress event. Subjects were randomly allocated to two treatments of 0 mg/d SCFP and 250 mg/d SCFP. Parameters examined over the two studies included body composition, body weight, feed intake, activity, running speed, stool quality. The following serum biomarkers were also measured: saliva cortisol (CORT), total antioxidant capacity (TAC), thiobarbituric acid reactive substances (TBARS), c-reactive protein (CRP), creatine kinase (CK), haptoglobin (HAP), serum amyloid A (SAA), TNF-α, immunoglobulin E (IgE), and immunoglobulin G (IgG). Subjects fed SCFP exhibited numeric net increases in lean mass (Table 1), numeric increases in stool quality, and significantly higher activity during exercise (P &lt; 0.05) vs CON (Table 2). The 500 mg/d SCFP group exhibited lower CK (P &lt; 0.03), increased HAP (P &lt; 0.001), increased SAA (P &lt; 0.05), increased TNF-α (P &lt; 0.007), increased CORT, improved TAC (P &lt; 0.001), reduced TBARS (P &lt; 0.01), IgE (P &lt; 0.001) and IgG (P &lt; 0.001), and increased CRP during transport (P &lt; 0.001) (Table 3). These results demonstrate that Labrador Retrievers supplemented with SCFP may exhibit improved vitality, utilization of nutrients, immune function, and reduced cellular damage when subjected to exercise and transport stress.
PSV-B-24 Palatability assessment of graded levels of grain distillers dried yeast (GDDY) fed to healthy adult cats
Authors: Kilburn Logan , Jolly-Breithaupt Melissa L , Balk Derek , Aldrich Charles G 
Published: October 2021

Abstract
Traditionally, yeast products have been added to companion animal diets to improve palatability. Grain distillers dried yeast (GDDY), a coproduct from ethanol production which contains yeast, may be a viable option in pet food. The objective of this study was to determine the effects of increasing levels of GDDY in cat diets compared to soybean meal. The control diet contained 15% soybean meal (CON) and GDDY was exchanged for soybean meal at either 5%, 10%, or 15% (5G, 10G, 15G). For each test, experimental treatments were compared to the control. Twenty cats were presented two bowls each containing approximately 100g of diet once daily for 2 days. Cats were given diet access for 4 hours and bowl placement was reversed on the second day. Total food consumption and first choice preference were recorded for each cat. Individual intake ratios (IR) were calculated (intake of each diet/total intake) and first choice (FC) was analyzed with a Chi2 test. When comparing 5G to CON, the IR was 0.970 with FC of 30/40 occasions (P = 0.0016). The IR for 10G was 0.538 and FC was 18/40 with no difference from the CON (P = 0.5271). The IR for 15G was 0.590 and FC was 19/40 with no difference from the CON (P = 0.7518). Overall, these results suggest that cats may prefer GDDY over soybean meal, but preference may be influenced by inclusion level with the greatest impact observed at 5% and no detrimental impact at 10 or 15%.
PSVII-20 Optimization of intestinal permeability assays to study the degree of fasting in gut permeability of unweaned Angus-Holstein bull calves
Authors: Pisoni Lucía , Devant Maria , Blanch Marta , Pastor Jose J , Marti Sonia 
Published: October 2021

Abstract
In-vivo assessments of intestinal permeability can be expensive and time consuming. Additionally, the correct choice of test molecules to use and the optimum sampling time under fasting situations needs be optimized. Fifteen unweaned Angus-Holstein bull calves (44.1 ± 2.0 kg and 14.7 ± 0.63 d) were randomly assigned to 1 of 3 treatments: Control (CT; n = 5): no fasting; fasted during 9 h (FAS9; n = 5); and fasted during 19 h (FAS19; n = 5). All calves were fed 2.5 L of MR and treatments were applied on d -1. Chromium-EDTA (Cr-EDTA), lactulose and D-mannitol were administered orally before blood collection. Samples were taken on d -4 and -1 before fasting and on d 0 and 2, at 60, 120, 180, and 240 minutes. To choose the best test molecule, correlations between serum concentration of the test molecules were used. To decide the optimum sampling time, data from d 0 were used to calculate area under the curve, then data were analyzed with mixed models with fasting degree and sampling time as fixed effects. Correlation between Cr-EDTA and D-mannitol was r= 0.92 (R2=84%), and correlation between Cr-EDTA and lactulose was r= 0.86 (R2=75%). Differences in AUC of Cr-EDTA between CT and t fasting treatments were observed up to 120 min. Differences in AUC of Cr-EDTA between FAS9 and FAS19 were observed later at 240 min. To optimize the intestinal permeability test, the use of only one test molecule might be sufficient. The Cr-EDTA was proposed to optimize the methodology due to price and simplicity of the analysis. The optimum sampling time after Cr-EDTA administration was 120 min when comparing fasting and control, and 240 min when comparing different fasting degrees.
PSXI-16 Evaluation of supplementation strategies for beef cattle bale-grazing grass hay in Winter
Authors: Undi Michael , Sedivec Kevin K K 
Published: October 2021

Abstract
Methods of supplementing beef cows while bale grazing grass hay were investigated in a study conducted for four winters, from 2016 to 2019, at the Central Grasslands Research Extension Center near Streeter, ND. Starting in the fall of each year, cows were assigned to eight groups of similar total body weight (BW) and allowed to bale graze one of four bale grazing treatments as follows: a) grass hay, b) grass hay supplemented with alfalfa hay, c) grass hay supplemented with corn DDGS, and d) grass hay treated with a liquid supplement. Two-day body weights and body condition scores (BCS) were taken at the start and end of the study. Final BW were greater (P ≤ 0.05) when cows were supplemented with DDGS and least when cows were not supplemented. Average daily gains were influenced by method of supplementation and year (P ≤ 0.025). When winters were cold, supplementation with alfalfa hay or a liquid supplement were not adequate to maintain cows resulting with weight loss. Final BCS were greatest (P ≤ 0.05) when cows were supplemented with DDGS and lowest on grass hay. Similarly, change in BCS was greatest in DDGS-supplemented cows and lowest on grass hay only. Calf birth weights, weaning weights and daily gains were not influenced (P &gt; 0.05) by method of supplementation. Results suggest that method of supplementation during bale grazing should be based on prevailing environmental conditions during winter. In severely cold winters, good-quality alfalfa hay or a liquid supplement are not adequate to meet requirements of pregnant beef cows in mid-gestation. Under such conditions, supplements such as corn DDGS will be needed to meet animal requirements. Supplementation with good-quality alfalfa hay or grass hay treated with a liquid supplement may be an option during mild winters.

Published: October 2021

Abstract
Our objective was to evaluate the effects of application rate (AR) of sodium lignosulfonate and propionic acid on the in vitro fermentation measures of high moisture alfalfa hay. Treatments (TRT) were sodium lignosulfonate (NaL) and Propionic Acid (PRP), which were applied at four AR: 0 (CON), 0.25, 0.5 and 1% (w/w fresh basis) to 20% bloom alfalfa hay (second cut) at 68.5% DM and packed into mini bales (10.3×10.8×13cm; 346 kg fresh/m3). The treated bales were stored for 33 days in open-top insulation boxes in a room kept at 22°C, after which they were dried, ground to 1 mm and incubated in vitro for 48hr with ruminal fluid from two ruminally cannulated Holstein cows in lactation. Gas kinetics were recorded using the Ankom RF Gas Production System. Data were analyzed as a randomized complete block design (5 blocks) with a 2 (TRT) x 4 (AR) factorial arrangement, and differences were declared at P ≤ 0.05. Both TRT increased apparent in vitro DM digestibility (DMD) at all AR relative to CON (54.3 vs 50.1 ± 1.20%, respectively). PRP increased asymptotic maximal (188.4) and rate of gas production (9.46) compared to NaL (179.7 ± 4.82 ml/g of incubated DM and 8.72 ± 0.45%/h, respectively). Total VFA were higher for PRP (117.5) vs NaL (114.8), and for both TRT at 1% relative to CON (118.9 vs. 113.8 ± 1.68mM). Acetate (A) was increased by both TRT at 1% (~73.5) and propionate (P) was increased by PRP at 1% (26.1) relative to CON (69.9 ± 1.10 and 24.2 ± 0.29mM, respectively), but the A:P ratio was higher for NaL at 1% (3.02) vs. CON (2.89 ± 0.04). In conclusion, NaL and PRP at 1% improved the rumen in vitro fermentation measures of high moisture alfalfa hay but PRP did so to a greater extent.
