9/5 on two questions).
71 participants were eligible and completed baseline (68 completed at least one follow up survey). We found significant improvements in the intervention group in knowledge, communication expectations, and caregiver-youth conflict behaviors in one or more waves; the control group demonstrated no significant improvements. When groups were compared, we found significant differences in knowledge, communication frequency, and conflict behaviors at 6 months.

Heart to Heart is feasible, acceptable, and preliminary outcomes data is promising. More research is needed to better establish evidence of efficacy for long-term behavior change in caregivers and youth.

NCT03331016.A simple bioassay that quantifies feed intake as an estimation of relative attractability of feeds containing different ingredients in the Pacific white shrimp Litopenaeus vannamei is described. Fish meal (FM), fish protein hydrolysate (FPH), squid meal (SqM) and casein (CN) were assessed at the same dietary level for their relative influence on feed intake rates of Litopenaeus vannamei. A bland diet containing 92% whole wheat grain meal, 6% diatomaceous earth and 2% alginate with a known low attractability was used as the standard control or base diet. Ingredients were added to the bland base control diet at a level of 3% as fed. Shrimp were stocked into 80 L glass tanks (n= 20 per tank) in a recirculating aquaculture system. Tanks were randomly assigned to one of five diet treatments (3tanks/treatment). Experiments measuring the attractability of each feed were conducted twice daily at 0900 hours and 1330 hours over a five day period. Orforglipron research buy For each experiment, 40 feed pellets (ca. 1 g) corresponding to the assigne consumption of diets containing certain ingredients can be considered as a valid method to estimate attractability.The de-agglomeration characteristics of single agglomerate-wall impaction are examined using high-resolution shadowgraph imaging. Experiments are performed to investigate the effects of constituent particle size (D 50 from 3-7 μ m) and air velocity on the individual size and velocity of de-agglomerated fragments at conditions relevant to dry powder inhalation systems. De-agglomerated fragment area and trajectories were used to differentiate between pseudo-elastic and inelastic collisions during de-agglomeration. Advanced image processing techniques have enabled provision of joint population distributions of fragment area and aspect ratio, which identify a bimodal dispersion of fragments during de-agglomeration. The bimodality is destroyed with increasing air velocity and also generally diminishes with time after impact. The experiment presented forms a platform for the detailed quantitative characterisation of de-agglomeration behaviour and can be useful towards the development and validation of related computational models for pharmaceutical dry powder inhalers.Circulatory arrest and left heart bypass are the most common approaches to manage perfusion during distal arch surgery. We report a novel perfusion technique utilized in the treatment of aneurysmal Komerrell's diverticulum (KD) and aberrant subclavian artery (ASA) that allows for a reliable conduct of perfusion. From 2016 to 2020, 12 adult patients with aneurysmal KD and ASA underwent repair of distal arch through lateral thoracotomy ipsilateral to the arch side using central partial bypass. Once the patients were fully heparinized the lower thoracic aorta and the right atrium were cannulated. The cannulas were connected to the cardiopulmonary bypass (CPB) circuit with an oxygenator. Partial bypass was initiated. Ventilation via anesthesia was continued as the mode of gas exchange to the upper body while the CPB circuit provided gas exchange to the lower body. In all patients, CPB was initiated allowing the patient to maintain a mean arterial pressure >60 mmHg in the femoral artery and a mean arterial pressure (MAP) >80 mmHg in the radial artery to allow adequate native ejection into the proximal circulation. The venous line was partially occluded to control the radial pressure. The aorta was cross clamped proximal and distal to the KD to isolate the aorta to be replaced. KD was excised in all patients having performed contralateral subclavian to carotid transposition previously. Once the aorta was reconstructed, clamps were released and the patients were weaned off CPB. All were extubated on the same day and there was no early mortality.Hybrid aortic procedures present many new challenges to the management of cardiopulmonary bypass (CPB). Reoperation or previous thoracic endovascular aortic repair (TEVAR) can further complicate these procedures, increasing the need for flexibility within the CPB system to execute multiple perfusion strategies as cases dictate. This technique describes the use of a bifurcated arterial circulation to provide both cerebral and lower body perfusion during a redo hybrid aortic arch reconstruction. The arterial line was divided into upper and lower body limbs, and connected to an 8-mm Dacron graft to the axillary artery, as well as a percutaneous 16-Fr. OptiSite femoral arterial cannula respectively. A 25-Fr. multi-stage femoral venous cannula was placed percutaneously as well. CPB was initiated utilizing both arterial cannulas with near-infrared spectroscopy and electroencephalogram to monitor the adequacy of cerebral perfusion. Moderate hypothermia of 26°C was induced and a CODA balloon (Cook Medical, Bloomington, IN) was deployed to occlude the proximal limb of a thoracic endovascular repair (TEVAR) graft; the common trunk of the debranched arch vessels was clamped proximally, allowing for simultaneous upper and lower body perfusion. Upon completion of the distal arch, the CODA balloon was removed and total body perfusion was reinitiated via central cannulation utilizing a sidearm on the arch graft.Cold agglutinins (CA) are auto-antibodies that adhere to erythrocytes in cold temperatures, and can result in agglutination of red blood cells. This process can cause complement-mediated intravascular hemolysis, which can be catastrophic. We describe a patient who developed CA during initiation of deep hypothermic circulatory arrest for emergent repair of Type A aortic dissection. The patient was found to have anti-I and anti-C antibodies and a positive direct Coombs test. CA resolved with re-warming, and resulted in no adverse events.Extracorporeal membrane oxygenation (ECMO) in the management of severely ill patients with COVID-19 has been reported in more than 5,827 cases worldwide according to the Extracorporeal Life Support Organization (ELSO). Several pre-existing conditions have been linked to an increase in COVID-19 mortality risk including obesity. The purpose of this research is to review the clinical experience from a cohort of 342 COVID-19 patients treated with ECMO in which 61.7% (211/342) are confirmed obese. Following institutional review board approval, we reviewed all 342 COVID-19 patients supported with ECMO between March 17, 2020 and March 18, 2021, at 40 American institutions from a multi-institutional database. Descriptive statistics comparing survivors to non-survivors were calculated using chi-square, Welch's ANOVA, and Kruskal-Wallis rank sum test as appropriate. Multivariable logistic regression was used to estimate the effect of body mass index (BMI) on the odds of survival while adjusting for age, gender, chronic001). Obesity does not seem to be a major risk factor for poor outcomes in COVID-19 patients supported with ECMO; however, age was moderately negatively associated with survival. The potential influence of other comorbidities on odds of survival among these patients warrant further investigation.Technology in healthcare has become increasingly prevalent and user friendly. In the last decade, advances in hands-free methods of data input have become more viable in a variety of medical professions. The aim of this study was to assess the advantages or disadvantages of hands-free charting through a voice-to-text app designed for perfusionists. Twelve clinical perfusion students using two different simulated bypass cases were recorded and assessed for the number of events noticed and charted, as well as the speed at which they accomplished these steps. Paper charts were compared with a custom app with voice-to-text charting capability. Data was analyzed using linear mixed models to detect differences in length of time until a chartable event was noticed, and how long after noticing an event it took to record the event. Timeliness of recording an event was made by assessing log-transformed time data. There was significantly more information recorded when charting on paper, while charting with voice-to-text resulted in significantly faster mean time from noticing an event to the recording of it. There was no significant difference between how many events were noticed and recorded. When using paper charting, a higher percentage of events that were missed were drug administration events, while voice charting had a higher percentage of missed events that were associated with cardioplegia delivery or bypass timing. With a decreased time interval between noticing an event and charting the event, speech-to-text for perfusion could be of benefit in situations where many events occur at once, such as emergency situations or highly active portions of bypass such as initiation and termination. While efforts were made to make the app as intuitive as possible, there is room for improvement.Retrograde autologous priming (RAP) is a process used to reduce hemodilution associated with the initiation of cardiopulmonary bypass (CPB). Previous studies have reported potential benefits to RAP; however, many of these studies do not evaluate the benefits of RAP with limited preoperative fluid administration combined with a condensed CPB circuit. We examined clinical metrics of patients who underwent RAP versus those who did not undergo RAP prior to the initiation of CPB. This was a retrospective data review of 1,303 patients who underwent CPB in the setting of open-heart surgery for a 2-year period. RAP was used on all patients between June 1, 2017 and June 30, 2018 (n = 519) and not used on patients between July 1, 2018 and June 30, 2019 (n = 784). Both groups were subjected to a low-prime CPB circuit volume of 800-900 mL. We compared the clinical metrics for packed red blood cell (PRBC) transfusion, oxygen delivery, postoperative acute kidney injury (AKI), Albumin utilization, ventilator time, Intensive Care Unit length of stay (ICU LOS), and 30-day mortality between the two groups. Our data analysis showed there were no statistically significantly differences between the two groups on the incidence of postoperative AKI, PRBC administration, ventilator time, ICU LOS or 30-day mortality. In the RAP group, there was a statistically significant lower oxygen delivery and a statistically significant increased volume of Albumin administered postoperatively, although those differences were so small, they were potentially not clinically significant. Our analysis revealed no significant benefit to performing RAP with limited preoperative fluid administration and minimized CPB circuit prime volume. We formalized a process that included limiting preoperative fluid administration and minimizing the CPB circuit volume so that we were not required to RAP and did not simultaneously sacrifice patient outcomes in other areas.
