It is Spring in Virginia, and that means that it is time for medical students to make their final decisions about which discipline of Medicine they will apply to for postgraduate training and to begin their application processes. I have long believed that most medical students with two hands and binocular vision can be successful in a surgical training program, if that is what they choose to do. However, obtaining a surgical residency is a competitive process, which means that the applicants must have their thoughts organized so that they can put their 'best foot forward' as they go through the application and selection process. The most challenging aspects of the application process for virtually everyone are writing personal statements and preparing for interviews, which will be even more complicated than usual, in the midst of the current pandemic. After more than four decades of helping students prepare for these daunting exercises, I have honed the advice that I give these applicants about the related challenges of writing about themselves and of answering questions in interviews. I believe that the candidates must convince the reviewers of their applications that they have, or can develop, the mental strategies necessary to become a capable surgeon. In this treatise, I will outline the mental strategies that I have found essential to achieving competency in a surgical discipline. The task of the applicants will be, therefore, to assert, with supporting evidence, that they are confident that they have, or can learn, these mental strategies.
Chylothorax is caused by thoracic lymphatic system injury that leads to lymph extravasates in the thoracic cavity. Cardiac surgery was the most common cause. Reports comparing therapeutic effects between enteral nutrition (EN) with medium-chain triglycerides (MCT) and total parenteral nutrition (TPN) are few and inconsistent. Our study aimed to analyze the incidence of chylothorax in children in our hospital and optimum nutritional management modalities.

We retrospectively reviewed the medical records of children admitted to our hospital with a diagnosis of chylothorax from 2014 to 2018. We analyzed the incidence of chylothorax, therapeutic effectiveness, and cost effectiveness of EN with MCT or TPN.

136 patients with chylothorax after surgery for congenital heart disease (CHD) were identified from 172 patients with chylothorax (79.07%); chylothorax occurred in 5.62% of all 2420 congenital heart disease surgeries that were performed during that period. Tetralogy of Fallot (TOF), ventricular septal defecficantly better than those of TPN, with lower costs. Therefore, we suggest that EN with MCT be chosen first to treat chylothorax caused by surgery with mild chest drainage volume when gastrointestinal tract function is allowed.
The relationship between perioperative hyperchloremia and postoperative acute kidney injury (AKI) is not well established. Our study aimed to evaluate the association between perioperative hyperchloremia and acute kidney injury in patients undergoing off-pump coronary artery bypass grafting (CABG).

Patients with coronary disease who underwent off-pump CABG between April 2017 and December 2019 were enrolled in this retrospective study. The patients with perioperative hyperchloremia were matched 11 to patients without perioperative hyperchloremia. The primary outcome was the postoperative acute kidney injury rate. The secondary outcomes included intensive care unit (ICU)-free days, postoperative hospitalization days, wound infection rate, and in-hospital mortality. Propensity score matching and univariate and multivariate logistic regression analyses were used in this study.

A total of 321 patients who underwent off-pump CABG were included in the analysis. see more Propensity score matching selected 83 pairs for the final comparison. The results showed that the postoperative AKI rate was significantly different between the hyperchloremia and no hyperchloremia groups (56.6% versus 15.7%; P < .001). The number of ICU-free days, postoperative hospitalization days, wound infection rate, and in-hospital mortality were similar between the two groups. In the multivariable, logistic regression analysis, hyperchloremia was independently associated with the development of postoperative AKI (odds ratio [OR] = 1.814, 95% confidence interval [CI] 1.072-3.070, P = .026).

Perioperative hyperchloremia is associated with an increase in the postoperative AKI rate among patients undergoing off-pump CABG.

Postoperative atrial fibrillation (PoAF) is a common complication after surgical mitral valve replacement. Late PoAF is independently associated with long-term mortality. This study aimed to test the utility of preoperative left atrial mechanical function as a predictor of early and late PoAF in clinical practice.

Patients (N = 150) with a rheumatic mitral valve who underwent mitral valve replacement with or without tricuspid valvuloplasty and who were in stable sinus rhythm were included. Baseline characteristics and transthoracic echocardiographic assessment information on the day before surgery were collected. Em, Em´, and Ei´ indicate early diastolic peak velocity of the mitral valve, early diastolic velocity at the lateral wall of the mitral annulus, and early diastolic velocity at the interventricular septal annulus, respectively.

Early PoAF was present in 59 of 150 patients (39.3%), and 32 of 150 patients (21.3%) developed late PoAF within 1 year after surgery. Among all of the variables examined, age, diabetes, early mitral filling velocity (Mitral E), left atrial mechanical function (Mitral A), Em/Em´, Em/Ei´, and mitral transvalvular gradient showed a significant correlation with PoAF. Only age, Mitral A, and mitral transvalvular gradient showed strong, significant correlations with the occurrence of late PoAF. In a multivariate analysis, predictors of late PoAF recurrence included early PoAF and Mitral A.

Routine evaluation of Mitral A is feasible and useful to predict early and late PoAF in patients with a rheumatic mitral valve undergoing surgical mitral valve replacement.
