Dobutamine should be used cautiously given its generally detrimental effects but may have an application when combined with norepinephrine in patients with low cardiac output. Management of chronic HF medications warrants careful consideration for continuation or discontinuation upon development of sepsis, and β-blockers may be appropriate to continue in the absence of acute hemodynamic decompensation. Optimal management of atrial fibrillation may include β-blockers after acute hemodynamic stabilization as they have also shown independent benefits in sepsis. Positive pressure ventilatory support and renal replacement must be carefully monitored for effects on cardiac function when HF is present.Purpose To investigate dairy and plant-based dairy alternatives (DPBDA) purchasing habits, including comparisons among locations of purchase and among subtypes of DPBDA, of families with preschool-aged children. Methods Expenditures on food and DPBDA were calculated using grocery and food receipts collected for 3 weeks from 51 households in and around Guelph, Ontario, Canada. DPBDA were coded by subtypes (alternatives, cheese/yogurt, cow’s milk, cream, and ice cream/other) and by locations of purchase, which were coded as big-box, discount, high-end, local/other, and midrange stores. Logistic regression using generalized estimating equations was used to investigate odds of purchasing DPBDA by location of purchase. All models included family income and number of children as potential confounders. Results Ninety-eight percent of families purchased cheese/yogurt, 92% purchased cow’s milk, and 35% of families purchased plant-based dairy alternatives. Families were more likely to purchase DPBDA from big-box stores than discount, midrange, or local/other stores (P less then 0.01) and were more likely to purchase cheese/yogurt than dairy alternatives, cream, or ice cream/other subtypes (P less then 0.01). Odds of purchasing were not different between cheese/yogurt and cow’s milk. Conclusion Families’ DPBDA purchasing habits differ by purchase location and subtype. Further research is warranted to understand the factors affecting these purchasing habits.Teen dating violence (TDV) has become more prevalent in our schools, exacerbated by the omnipotent presence of social media and portals of what dating and gender roles “should be” in Hollywood films and television shows. It is important to recognize that TDV is a threat to mental health, and potentially physical health, and school nurses should develop a framework for recognizing problematic social, physical, and emotional interactions between students. This article describes typical presentations of TDV through a case, providing a mnemonic for recognition and resources for prevention.Little is known about athletes’ perceptions of emerging dietary guidance on plant-based diets (PBD). To explore knowledge and perceptions of PBD among competitive and recreational athletes, an online survey was developed, pilot tested, and sent via email to athletes recruited from 2 Canadian post-secondary institutions. Survey questions explored athletes’ understanding and views of the proposed Canadian dietary guidelines emphasizing plant-based proteins. Data were analyzed using grounded theory approaches. Forty-eight athletes participated in the survey. Two major themes emerged (i) athletes had mixed perceptions of plant-based eating (PBE) and (ii) athletes associated PBE with broader food system concerns. Athletes have the potential to be important advocates of healthy and sustainable eating among peer groups and the general public. For effective promotion of PBE, the unique nutrient requirements and performance goals of athletes should be considered. Roblitinib cell line Messaging to encourage a flexible rather than strict view of PBD may be a more feasible and acceptable approach when working with athletes.Controversy exists in the timing of spinal cord decompression following severe traumatic spinal cord injury (SCI). In addition, the exact definition of decompression versus anatomical alignment and internal fixation is not adequately defined. We recently questioned the significance of the timing of decompression in severe SCI which was submitted and printed in the J of Neurotrauma with the following title Efficacy of Ultra-Early (24-138.5 h) Surgery with Magnetic Resonance Imaging-Confirmed Decompression in American Spinal Injury Association Impairment Scale Grades A, B, and C Cervical Spinal Cord Injury. Burke JF, Fehlings MG, Dhall SS. J Neurotrauma. 2020 Apr 16. doi 10.1089/neu.2020.7034. Online ahead of print. PMID 32299278. The present submission is in response to this LETTER to the Editor We tried to answer many of the significant questions presented by the authors aimed at mitigating the present challenges.Purpose To analyze the structural variation of the aortic arch and the supra-aortic arteries and establish an average spatial configuration that would be a pattern for a “universal double fenestration” design for physician-modified endovascular grafts (PMEGs) used in total thoracic endovascular aortic repair (TEVAR). Materials and Methods Aortic arch morphology was retrospectively analyzed by reviewing the preoperative thoracic computed tomography angiography scans in 33 consecutive patients (mean age 68 years; 27 men) treated between January 2017 and March 2019 using double-fenestrated PMEGs for zone 0 TEVAR. Image analysis was completed according to a standardized technique on a vascular workstation with center lumen line reconstruction for all measurements. Variations in branching pattern of the aortic arch were classified into 8 types. Results The arch trunk configuration was type I in 26 patients (79%), type II in 5 (15%), type III in 1, and type IV in 1. Mean aortic diameters at the level of mid ascending aorta, innominate artery (IA), left common carotid artery (LCCA), and left subclavian artery (LSA) were 35.7±3.7, 34.2±4.5, 33.3±6.7, and 33.7±4.7 mm, respectively. Mean diameters of the trunk were 12.2±1.7, 7.5±1.4, and 8.0±0.8 mm, respectively. Mean longitudinal center to center lengths were 15.9±2.5 mm between the LSA and LCCA and 12.1±3.0 mm between the LCCA and IA. Mean clock positions using the LSA as reference were 1250 for the IA and 1205 for the LCCA. In 32 patients (97%) all the supra-aortic branch vessels fit perfectly inside two delimited areas defined by a proximal common square area of 30×30 mm for the IA and LCCA and a second distal 8-mm-diameter circle for the LSA. Conclusion Variations of the aortic arch anatomy are numerous and common. A general morphological pattern is described that delimits the aortic area where these variations occur. This information can be utilized for the design of an off-the-shelf double-fenestrated stent-graft for zone 0 TEVAR.
