Background: The risk of the Ross procedure continues to be debated. We sought to determine the immediate outcomes of the Ross procedure in a large consecutive cohort that included patients undergoing reoperative cardiac surgery and/or concomitant cardiac procedures.
Methods: Between March 1987 and September 2019, 702 patients underwent a full root Ross procedure. There were 530 male patients and 172 female patients, with a mean age of 41.6 years. One hundred and one patients had at least one previous sternotomy; 323 patients had concomitant procedures. Patients were stratified into 2 groups: simple and complex. Simple Ross patients were those who had no previous sternotomy and had only minor concomitant procedures performed at the time of their Ross, such as aortoplasty or closure of patent foramen ovale. The complex Ross group included patients with at least one previous sternotomy and/or additional procedures that we deemed complex, such as ascending aortic replacement and mitral valve repair. Complexity and group outcomes were evaluated in consecutive terciles of time.
Results: There were 7 (1%) operative deaths. Morbidity affected 46 other patients (6.6%). The simple Ross group comprised 419 patients (59.7%), with mortality in 3 (0.7%) and morbidity in 20 (4.8%). The complex Ross comprised 283 patients (40.3%), with mortality in 4 (1.4%) and morbidity in 26 (9.2%). Simple Ross cases decreased in volume over time, with complex cases increasing from 34% to 48%.
Conclusions: Excellent results can be achieved with the Ross procedure despite broader indications that include patients with previous sternotomy and with the need for concomitant procedures.

Objectives: Research supports cognitive behavioral therapies for nightmares (CBT-N) in adults. However, the nuances of implementation and unstandardized nomenclature for treatment components has created confusion in the field. To provide clarification, an expert consensus panel convened to review treatment manual components and to develop guidelines for the standardized implementation and terminology of CBT-N.

We previously developed human CAR macrophages (CAR-M) and demonstrated redirection of macrophage anti-tumor function leading to tumor control in immunodeficient xenograft models. Here, we develop clinically relevant fully immunocompetent syngeneic models to evaluate the potential for CAR-M to remodel the tumor microenvironment (TME), induce T cell anti-tumor immunity, and sensitize solid tumors to PD1/PDL1 checkpoint inhibition. In vivo, anti-HER2 CAR-M significantly reduce tumor burden, prolong survival, remodel the TME, increase intratumoral T cell and natural killer (NK) cell infiltration, and induce antigen spreading.

Background: The poultry industry faces challenges with the high cost and environmental impact of Soybean meal. Feather meal, a byproduct with low digestibility due to its keratin content, is a potential alternative. Recent biotechnological advances, including enzymatic and bacterial hydrolysis, have enhanced its digestibility and nutritional value.

The snub-nosed, reclining, and serene image of the fetus is commonplace in cultural representations and analyses of obstetric ultrasound. Yet following the provocation of various feminist scholars, taking the fetal sonogram as the automatic object of concern vis-à-vis ultrasound cedes ground to anti-abortionists, who deploy fetal images to argue that life begins at conception and that the unborn are rights bearing subjects who must be protected. How might feminists escape this analytical trap, where discussions of ultrasonics must always be engaged in the act of debunking? This article orients away from the problem of fetal representation by employing a method which may appear to be wildly unsuitable: media archaeology.
