Authors: Hao YangYi 
Published: October 2021

Abstract
Our objective was to evaluate the effects of body condition score (BCS) on the milk production and energy balance of transition dairy cows. Seventy-five multiparous dairy cows were separated into four groups according to the BCS, HH (4.25 ± 0.23 and 3.35 ± 0.19 BCS, pre and postpartum, respectively, n = 17), HM (4.14 ± 0.15 and 2.92 ± 0.24, n = 19), MM (3.10 ± 0.21 and 2.78 ± 0.17, n = 23), ML (2.88 ± 0.23 and 2.46 ± 0.19, n = 16). The milk yield, rumen pH, etc., data were collected and analyzed using a one-way ANOVA model in SAS (SAS version 9.4, SAS Institute Inc., Cary, NC, USA). The ML group had a higher milk yield and total solid yield than the MM group (P &lt; 0.05), while the HH and HM groups had no difference with other groups. The HM and ML groups had a higher milk fat content than the MM group (P &lt; 0.05), while the HH group had no difference with other groups. Milk protein content in the HH group was higher than the ML group (P &lt; 0.05). The milk lactose, total solids, urea content in these groups had no difference. The ML group had a higher milk acetone content than the HH group (P &lt; 0.05). The BCS change in the HH and HM groups was higher than the MM and ML groups, and that in the ML group was higher than the MM group (P &lt; 0.05). The rumen pH had no difference within these groups. These findings collectively indicated the prepartum dairy cow with middle BCS would have a more efficient body fat utilization and a better milk production performance. Furthermore, reducing body fat loss is necessary to avoid the negative energy balance.

Abstract
A total of 90 young crossbreed bulls (initial weight=228.04±7.06 kg) were used in a 171-day feeding trial in order to evaluate the combination of supplemental blend of essential oils (Crina® Ruminants; DSM Nutritional Products) plus 25-hydroxy-vitamin-D3 (HyD®, DSM Nutritional Products; EO+HyD) on growth performance and carcass characteristics in cattle finishing under tropical conditions. Cattle were blocked by weight into 2 blocks and randomly allocated to 2 treatments (9 pens/treatment, 5 bulls/pen). Cattle were fed with a steam-flaked corn-based diets (average diet NEm= 1.95 Mcal/kg during first 84-d, and 2.15 Mcal/kg during the remaining 87-d). Treatments consisted of: 1) EO+HyD supplementation along fattening period (171-d), or 2) supplementation with monensin (Rumensin®, Elanco Animal Health; 20 mg/kg diet) during the first 84-d and monensin (20 mg/kg diet) plus virginiamycin (Stafac®, Phibro Animal Health; 20 mg/kg diet) during remaining time (87-d). The average THI during course of the experiment was 76.67±2.7 with a maximum of 85.46±2.2 and minimum of 68.29±2.6. There were no statistical differences (P &gt; 0.10) between EO+HyD and ionophores/antibiotic supplemented cattle on DM intake (7.575 vs 7.534 kg/d), average daily gain (1.433 vs 1.406 kg), or gain-to-feed ratio (0.189 vs 0.187). However, cattle fed with EO+HyD tended (P = 0.07) to have heavier carcass weight in 5.2 kg (304.9 vs 299.7 kg), showed greater LM area (89.89 vs. 82.77 cm², P &lt; 0.01) and greater estimated retail yield (1.6%, P = 0.02) than cattle receiving ionophores/antibiotic mixture. Cattle receiving EO+HyD showed more percentage of carcass classified as Choice (14.28 vs 13.33%) and “Select” (59.52 vs 44.44%) and lower percentage of carcass classified as “Standard” (26.20 vs 42.23%). The combination of a blend of essential oils plus 25-hydroxy-Vit-D3 (EO+HyD) in finishing phase improve carcass characteristics. Supplemental EO+HyD is a viable alternative to supplemental monensin, or monensin plus virginiamycin used in growing-finishing diets for feedlot cattle.

Abstract
This study was conducted to determine the influence of glycerol and bypass fat supplementation on growth performance of early fattening Hanwoo steers under heat stress. Thirty-six Hanwoo steers were randomly allocated into 4 treatments based on BW and age for 112 days from the beginning of July to the end of October 2020. Experimental treatments were divided into four by the type of energy supplements: Control (CP, 14%; TDN 71.9), glycerol addition (GL; CP, 14%; TDN 74.9), bypass fat addition (BF; CP, 14%; TDN 74.9), and glycerol plus bypass fat additive (GL+BF; CP, 14%; TDN 74.9). During the experimental period, automatic temperature-humidity recorders were used for measuring every 10 minutes in the pen. The temperature-humidity index (THI) range of the 1st and 2nd periods was recorded above the threshold (THI 75~77) level based on the Korean beef heat stress index, and the average THI of the 2nd period was 79.91, being the mild-moderate (THI 78~81) level. The dry matter intake (DMI) and average daily gain (ADG) did not show significant differences in all treatments during the whole period. The feed conversion ratio (FCR) during 1st and 2nd periods showed the same pattern because FCR is related to DMI and ADG. Additionally, the rectal temperature showed no significant difference in all treatments, but a significant difference in each period (P &lt; 0.05). The results demonstrated that early fattening Hanwoo steers under mild-moderate stress did not affect DMI and productivity but 9.8% of GL or 1.9% BF in a concentrate only could be included in Hanwoo steers diets without decreasing palatability. In addition, increasing the energy content in the feed by 5% did not lead to a difference in productivity. Further studies would be needed on the effect of increasing the energy density on productivity under more severe thermal stress conditions.
PSXIV-7 Performance and environmental benefits from biochar supplementation in beef cattle grazing systems

Abstract
Reducing greenhouse gas (GHG) emissions from beef cattle production systems has continuously been recognized as an important strategy to help mitigate climate change. This experiment was conducted to determine the optimum inclusion level of biochar (Oregon Biochar Solution, White City, OR) in the diet to reduce enteric methane (CH4) emissions from beef cows. Biochar is a stable form of carbon produced through low-oxygen and high-temperature pyrolysis of organic matter (typically forestry waste). Using a 4 x 4 Latin square design, pregnant beef cows (n = 8) of similar weight and stage of pregnancy were supplemented with biochar daily at 0, 1, 2, or 3% of total dry matter intake (DMI). Biochar was added to a pellet containing 45% biochar, 42.5% wheat midds, 10% canola oil, and 2.5% dry molasses to facilitate ease of feeding and encourage biochar consumption. Each 21-day period consisted of 14 days for diet adaptation and 7 days for data collection. Enteric gas emissions were measured using C-Lock GreenFeed trailers (C-Lock Inc., Rapid City, SD, USA) and DMI was collected using Insentec feeders (Insentec, Voorsterweg, The Netherlands). Enteric CH4 emissions expressed in g CH4/day, g CH4/kg DM, and g CH4/kg BW were not affected by biochar supplementation (P ≥ 0.41), although the 3% inclusion was numerically lowest. For all parameters expressing CH4 emissions, linear and quadratic effects for inclusion rate were not significant (P ≥ 0.19). Dry matter intake and cow body weights were not affected by biochar supplementation (P ≥ 0.34). These results suggest that biochar was ineffective for reducing CH4 emissions from beef cows fed a high forage diet (50% haylage, 30% straw, 17% corn silage) with no effects on animal performance. Further research should investigate whether type of biochar or higher inclusion levels of biochar can reduce CH4 emissions from beef cattle.
PSXIV-14 Supplementation of high-grain diet with red osier dogwood affects in vitro digestibility and fermentation characteristics
Authors: Yang Wenzhu 
Published: October 2021

Abstract
Red osier dogwood (ROD) is a native shrub plant rich in phenolic compounds with antimicrobial properties. The objective of this study was to evaluate the effects of substituting barley silage with either raw ROD or ROD extract (RODE) in high-grain (HG) diet under a low media pH (5.8) on gas production (GP), dry matter (DM) disappearance (DMD) and fermentation characteristics in batch cultures. The study was a completely randomized design with 4 treatments: 1) control diet (10% barley silage and 90% barley concentrate, DM basis), control diet supplemented with 2) monensin (30 mg/kg diet DM; positive control), 3) substitution of 3% ROD or 4) 3% RODE for an equal portion of silage. Inoculum was obtained from 2 ruminally fistulated beef heifers offered the HG diet. Substrate ground (1 mm) was incubated for 24 h and the experiment repeated twice. The GP did not differ among treatments (147 ml/g DM), but the DMD differed (P &lt; 0.02) at highest for control (69.4%), lowest for ROD (58.4%) and intermediate for other treatments (64.1%). Total volatile fatty acid (VFA) concentration (mM) tended (P&lt; 0.08) to be lower with ROD (80.5) and monensin (80.1) than control (83.9). Acetate proportion was greater (P = 0.02) with ROD (46.2%) and RODE (46.9%) than control (42.4%) and monensin (42.3%). However, the propionate proportion was greater (P = 0.05) with monensin (32.1%) than other treatments (averaged 30.1%). Consequently, acetate to propionate ratio (A:P) of ROD (1.52) and RODE (1.56) was higher than monensin (1.32; P &lt; 0.01) and control (1.44; P &lt; 0.08). Differences in variables measured between ROD and RODE were minimal. These results indicated that the decreased DMD along with increased A:P with addition of ROD or RODE suggests that both ROD and RODE may be beneficial to HG fed cattle for reducing risk of rumen acidosis without negatively impacting fibre digestion.

Abstract
The aim with this trial was to evaluate three nutritional plans with the addition of 25-hydroxy-vitamin-D3 (HyD®) on performance of grazing Nellore steers in dry season. One hundred and twenty Nellore calves (iBW ± 267 kg; age, 9 mo) were randomly allocated to six paddocks (n = 20/paddock), in the following nutritional plans: mineral-proteic supplementation (PS; Fosbovi® Proteico 35; at 0.1% BW); PS with sodium monensin (PSM; Fosbovi® Proteico 35 M; at 0.1% BW); and mineral-protein-energetic supplementation (PES; Fosbovi® Proteico-Energético 25; at 0.3% BW); all three fed with or without addition of 1 mg/animal/d of 25-hydroxy-vitamin-D3 (HyD®), totaling six treatments. Both HyD® and supplements were provided by DSM Nutritional Products Brasil S.A. The intake and animal weight were collected daily and individually using an automatic feeder/scale system located in each paddock. Data were analyzed using the mixed procedure of SAS and means were compared by orthogonal contrasts (P &lt; 0.05). Animals fed PSE, when compared to PSM and PS, presented higher ADG (PSE = 0.290 vs. PSM= 0.130 and PS = 0.030 kg/day; P &lt; 0.01), FBW (PSE = 302.5 vs. PSM = 282.6 and PS = 271.7 kg; P &lt; 0.01) and supplement intake (PSE = 1.640 vs. PSM = 0.190 and PS = 0.210 kg/day; P &lt; 0.01). Additionally, regardless of nutritional strategy, HyD® supplementation increased ADG in 32 g/day (0.165 vs. 0.133 kg/day; P = 0.05) and FBW in 3.9 kg (287.5 vs. 283.6 kg; P = 0.05), compared to not-supplemented calves. No effects on supplement intake (either expressed in kg/day or %BW) were observed for HyD®. We conclude that 1 mg of HyD® can optimize performance of protein and protein-energetic supplemented cattle raised in tropical conditions during dry period.

Abstract
Portable accumulation chambers (PAC) enable gaseous emissions from small ruminants to be measured over a 50 min period, to date however, the repeatability of consecutive days of measurement in the PAC has not been investigated. The objectives of this study were to investigate: 1) the repeatability of consecutive days of gaseous measurements in the PAC, 2) the number of days required to achieve precise gaseous measurements, and 3) to develop a prediction equation for gaseous emissions in sheep. A total of 48 ewe lambs (c. 10 to 11 mo of age) were randomly divided into four measurement groups each day, for 17 consecutive days. Gaseous measurements were conducted between 0800 h and 1200 h daily. Animals were removed from perennial ryegrass silage for at least 1 h before measurements in the PAC and animals were assigned randomly to each of the 12 chambers. Methane (CH4; ppm) concentration, oxygen (O2; percentage) and carbon dioxide (CO2; percentage) were measured at 3 time points (0, 25, and 50 min after entry of the first animal into the first chamber). To quantify the effect of animal and day variation on gaseous emissions, between-animal, between-day and error variances were calculated for each gaseous measurement using a linear mixed model. The number of days required to gain a certain precision (defined as the 95% confidence interval (CI) range) for each gaseous measurement was also calculated. For all 3 gases the between-day variance (39% to 40%) accounted for a larger proportion of total variance compared to between-animal variance, while the repeatability of 17 consecutive days of measurement was 0.36, 0.31 and 0.23 for CH4, CO2 and O2, respectively. Correlations between consecutive days of measurement were strong for all 3 gases; the strongest correlation between d 1 and the remaining days for CH4, CO2 and O2 was 0.71 (d 1 and d 6), 0.77 (d 1 and d 2) and 0.83 (d 1 and d 5), respectively. A high level of precision was achieved when gaseous measurements from PAC were taken over 3 consecutive days. The prediction equation over-estimated gaseous production for all 3 gases: the correlations between actual and predicted gaseous output ranged from 0.67 to 0.71, with the r 2 ranging from 0.45 to 0.71. Results from this study will aid the refinement of the protocol for the measurement of gaseous emissions in sheep using the PAC.
Hemofiltration in the Management of Severe Pediatric Burns: Experience in a UK Burns Centre and Systematic Review
Authors: Rice Michael , Ibrahim Ibrahim , Aly Mohamed Ismail 
Published: October 2021

Abstract
Pediatric burns are life-threatening injuries due to the acute injury and secondary complications. In acute-phase burns, hypovolemia and vasoconstriction cause renal impairment. Sepsis and multiorgan failure compound the problem resulting in morbidity and mortality. This paper outlines 5 years’ experience using hemofiltration in major pediatric burns, and a review of the current literature. Retrospective patient data collection was undertaken identifying relevant pediatric burns undergoing Continuous Veno-Venous Hemofiltration. Data were analyzed to identify demographics, indication, duration of therapy, and outcomes. A systematic review was also performed using PRISMA principles. PubMed, Science Direct, and OVID databases were explored and relevant papers were included. From January 2015 to December 2019, hemofiltration was utilized in five cases. Age range 3 to 15 years (mean: 12), four males/one female, and mean weight 56 kg (12–125 kg). TBSA 21% to 61% (mean: 37.6%), mechanism of injury was scald—60%, flame—40%. Overall survival was 100%. Three patients were filtered for a brief period during the first 24 hours to correct metabolic acidosis and control temperature. Two patients required prolonged therapy. All patients recovered without further long-term renal support. A total of 3814 papers were identified for systematic review. Three were considered relevant for inclusion. This paper reflects the benefits of hemofiltration in the management of severe pediatric burns. Renal replacement therapy is useful in managing metabolic acidosis, temperature control, and renal failure. The current literature supports judicious use on a patient-by-patient basis. Given the lack of evidence in the literature, further studies are required to establish guidelines for the use of hemofiltration in pediatric burns.
Fibrocystic Changes of the Breast: Radiologic–Pathologic Correlation of MRI

Published: October 2021

Abstract
Breast MRI provides high sensitivity but modest positive predictive value for identifying breast cancers, with approximately 75% of MRI-guided biopsies returning benign pathologies. Fibrocystic change (FCC) is a descriptive term used colloquially by many radiologists (and falling out of favor with many pathologists) to refer to several benign entities encountered in the breast. Many of the benign entities believed to comprise FCC can show enhancement on MRI. Recognizing the pathologic correlates of these enhancing lesions should help guide management after such a result on MRI-guided biopsy. Premenopausal women may present with clinical symptoms attributed to FCC, including pain, nipple discharge, breast lumps, or discrete masses. Benign entities associated with FCC include proliferative lesions such as usual ductal hyperplasia and sclerosing adenosis, and nonproliferative lesions including cysts, apocrine metaplasia, and stromal fibrosis. Fibrocystic change can be diffuse or focal. Diffuse FCC usually presents as non-mass enhancement (NME), often with persistent kinetics. Focal FCC can present as an irregular mass or focus with variable enhancement patterns including washout kinetics. Following a benign concordant MRI-guided biopsy result of one or more of the above entities, follow-up with MRI in 12 months is reasonable. Accurate radiologic–pathologic correlation can be achieved when careful review of histologic findings is carried out in the context of MRI features.
To Look or Not to Look? Axillary Imaging: Less May Be More
Authors: Mango Victoria L , Pilewskie Melissa , Jochelson Maxine S 
Published: October 2021

Abstract
Axillary lymph node status in patients with breast cancer is an important prognostic indicator and often guides vital treatment decisions. Although in many cases imaging plays a crucial role in the assessment of the axilla, it is essential that targeted axillary US and/or image-guided biopsy of an axillary lymph node be performed by the radiologist only when clinically appropriate. This decision-making process requires multidisciplinary communication and collaboration among radiologists, surgeons, medical oncologists, and radiation oncologists. Our goal is to review axillary imaging for patients with breast cancer in two distinct clinical settings, the patient with newly diagnosed breast cancer who meets American College of Surgeons Oncology Group Z0011 criteria and patients undergoing neoadjuvant chemotherapy, with a specific focus on potential reasons to not perform axillary US and/or image-guided biopsy in these settings.
On theĀtmanThesis Concerning Fundamental Reality
Authors: Fasching Wolfgang 
Published: October 2021

AbstractThe central thesis of the philosophy of Advaita Vedānta is the doctrine of the identity of brahman (the absolute) and ātman (the self). Brahman is essentially sat, being as such in the sense of the dimension of existence in which all worldly goings-on take place. The ātman is conceived as the “seer,” i.e., as the pure subject qua the to-whom of any experiential givenness; and this subject, in turn, is understood not as some entity that performs the seeing but as nothing but the very seeing itself, i.e., as consciousness in the sense of the abiding presence-realm in which permanently changing experiential contents come to givenness. The Advaitic thesis is that this presence-realm—the seeing that takes place “in us”—is ultimately nothing other than the universal being-dimension—brahman—itself, (seemingly) modified by the mental contents of an innerworldly individual. This paper attempts to vindicate this doctrine by a series of reflections on the nature of the I and of reality as such. It argues that Advaita Vedānta can be viewed as a version of cosmopsychism in its idealist version which does not view consciousness as one of the features of the cosmos as a whole, but as its exclusive intrinsic nature, i.e., as the very essence of being as such.

AbstractBackgroundGuidance on the recommended durations of antibiotic therapy, the use of oral antibiotic therapy, and the need for repeat blood cultures remain incomplete for gram-negative bloodstream infections. We convened a panel of infectious diseases specialists to develop a consensus definition of uncomplicated gram-negative bloodstream infections to assist clinicians with management decisions.MethodsPanelists, who were all blinded to the identity of other members of the panel, used a modified Delphi technique to develop a list of statements describing preferred management approaches for uncomplicated gram-negative bloodstream infections. Panelists provided level of agreement and feedback on consensus statements generated and refined them from the first round of open-ended questions through 3 subsequent rounds.ResultsThirteen infectious diseases specialists (7 physicians and 6 pharmacists) from across the United States participated in the consensus process. A definition of uncomplicated gram-negative bloodstream infection was developed. Considerations cited by panelists in determining if a bloodstream infection was uncomplicated included host immune status, response to therapy, organism identified, source of the bacteremia, and source control measures. For patients meeting this definition, panelists largely agreed that a duration of therapy of ~7 days, transitioning to oral antibiotic therapy, and forgoing repeat blood cultures, was reasonable.ConclusionsIn the absence of professional guidelines for the management of uncomplicated gram-negative bloodstream infections, the consensus statements developed by a panel of infectious diseases specialists can provide guidance to practitioners for a common clinical scenario.
