Ultrasound-guided radiofrequency ablation has shown promising results for nonsurgical treatment of benign thyroid nodules. The purpose of this study is to investigate public perceptions of radiofrequency ablation and identify salient decision factors for benign thyroid nodules treatment.

An internet-based survey was distributed via an online platform. Survey participants were prompted to envision having a benign thyroid nodules and were assessed on risk acceptance, willingness to pay, and importance of decision factors (eg, cost, risk, scarring) regarding treatment with either radiofrequency ablation or standard surgery.

A total of 830 respondents (male 46.3%, median age 35 years) were included. Respondents ranked the most important factors for benign thyroid nodules treatment as risk of missing cancer and risk of permanent hoarseness (mean score 5.23 and 4.50 out of 7, respectively). Female respondents ranked missing cancer higher in importance compared with other decision factors (coefficient= 0.251, previous scars are both associated with a proclivity toward nonsurgical treatment and radiofrequency ablation.
The need to continue providing care to patients during the corona virus disease 2019 pandemic facilitated telemedicine's rapid adoption, including in surgical clinic settings. Our purpose was to evaluate integration of telemedicine into an academic colorectal surgery practice and assess physician experiences providing telemedicine care.

Patients seen in colorectal surgery clinic by telemedicine and in person from March 31, 2020 to August 31, 2020 were evaluated. Demographic and clinical outcomes were assessed for patients. Physician responses to a survey were collected.

Two hundred and thirty-one telemedicine visits were performed by 4 physicians, comprising 20% of visits during the study period. Patients were 47.6% male and 90.9% Caucasian. In addition, 85.7% were established patients and 21.2% were postoperative visits. Diagnoses evaluated by telemedicine included benign and malignant anorectal and colorectal disease as well as inflammatory bowel disease. All providers reported being able to provide adentified significant differences in ethnicity between patients seen via telemedicine and those seen in person. Telemedicine represents an exciting advancement in patient care, although ongoing study is required regarding providing access to this technology to all colorectal surgery patients, particularly minority populations.
Major ventral hernia surgeries are commonly performed. Despite guideline recommendations for chemo-thromboprophylaxis in the perioperative period, the optimal timing for its initiation is unknown. We characterized the variability in perioperative chemoprophylaxis in elective major ventral hernia surgery and determine whether timing of chemoprophylaxis affects bleeding and symptomatic venous thromboembolism.

Retrospective analysis of all elective major ventral hernia surgery undertaken between January 1, 2014, and December 31, 2019, at 14 hospitals across Australia. Major bleeding was defined as the need for blood transfusion, reoperation, or >20 g/L fall in hemoglobin. Clinical venous thromboembolism was defined as imaging-proven symptomatic disease <30 days postsurgery. Propensity score matched analysis was used to validate primary findings.

In the study, 3,384 hernia repairs were analyzed. Chemoprophylaxis was administered early (before skin closure), postoperatively, or not given in 856 (25.3%).
The incidence of clinical venous thromboembolism after elective major ventral hernia repair is low. Variability in perioperative thromboprophylaxis is high. Early chemoprophylaxis increases bleeding risk without appreciable additional protection from venous thromboembolism.
The literature has reported worse in-hospital outcomes for patients with atrial fibrillation. The objective of the following study is to provide detailed results on the long-term impact of postoperative atrial fibrillation on survival and hospital readmission in cardiac surgery.

All patients undergoing open cardiac surgery were reviewed with the exclusion of preoperative atrial fibrillation or patients undergoing ventricular assist device, transplant, or Cox-Maze procedures. Propensity matching (11) was performed to ensure similar baseline characteristics. Multivariable analysis identified significant associations with mortality and readmission.

A total of 12,227 patients with cardiac disease were divided into 7927 patients (64.8%) without postoperative atrial fibrillation and 4300 patients (35.2%) with new-onset postoperative atrial fibrillation. Propensity matching (11) yielded 4275 risk-adjusted pairs. There was no difference between the nonpostoperative atrial fibrillation versus postoperative atrias for heart failure on long-term follow-up.
Patients in the postoperative atrial fibrillation cohort had worse perioperative morbidity, lower survival, and more readmissions for heart failure on long-term follow-up.
Studies have noted racial/ethnic disparities in coronary artery disease intervention strategies. We investigated trends and outcomes of coronary artery disease treatment choice (coronary artery bypass grafting or percutaneous coronary intervention) stratified by race/ethnicity.

We queried the National Inpatient Sample for patients who underwent isolated coronary artery bypass grafting or percutaneous coronary intervention (2002-2017). Outcomes were stratified by race/ethnicity (White, African American, Hispanic, Asian). Multivariable logistic regression evaluated associations between race/ethnicity and receiving coronary artery bypass grafting versus percutaneous coronary intervention, in-hospital mortality, and costs.

Over the 15-year period, 2,426,917 isolated coronary artery bypass grafting surgeries and 7,184,515 percutaneous coronary interventions were performed. Compared with White patients, African American patients were younger (62 [interquartile range, 53-70] vs 66 [interquartile range, 57-75] rvention for coronary artery disease differed by race/ethnicity. African American patients had lower odds of undergoing coronary artery bypass grafting and worse outcomes. Reasons for these differences merit further investigation to identify opportunities to reduce potential disparities.
In this contemporary national analysis, risk-adjusted frequency of coronary artery bypass grafting versus percutaneous coronary intervention for coronary artery disease differed by race/ethnicity. African American patients had lower odds of undergoing coronary artery bypass grafting and worse outcomes. Reasons for these differences merit further investigation to identify opportunities to reduce potential disparities.
The study objective was to evaluate the clinical implication of left ventricular diastolic dysfunction in patients with chronic severe aortic regurgitation undergoing aortic valve replacement.

We reviewed the medical records of 323 patients (age, 56.3±14.1years; 111 female) who underwent aortic valve replacement for chronic severe aortic regurgitation between 2005 and 2019. Left ventricular diastolic dysfunction was assessed by the ratio of peak left ventricular inflow velocity over mitral annular velocity (E/e'). The study end point was the composite of death and heart failure requiring hospital admission.

The E/e' ratio was significantly correlated with age, left atrial dimension, left ventricular end-diastolic volume, mitral regurgitation grade, and tricuspid regurgitation grade (all P<.001). During follow-up (1748.3 patient-years), death and heart failure occurred in 36 patients (2.06/patient-year) and 9 patients (0.53/patient-year), respectively. In multivariable analysis, E/e' ratio (per 5 increment, hazard ratio, 1.32; 95% confidence interval, 1.02-1.71; P=.03), age (hazard ratio, 1.06; 95% confidence interval, 1.03-1.10; P<.001), and left ventricular ejection fraction (hazard ratio, 0.94; 95% confidence interval, 0.90-0.98; P=.002) were independent predictors of death and heart failure. The 5-year heart failure-free survival was 94.9%±1.7% in patients with E/e' less than 15% and 84.2%±4.2% in patients with E/e' 15 or greater (P<.001).

The E/e' ratio was significantly associated with adverse outcomes in patients with chronic severe aortic regurgitation undergoing aortic valve replacement and may be useful as a prognostic marker in such patients.

Tacrolimus, one of the immunosuppressive agents, is used to prevent tissue rejection in renal transplant recipients, but the relationship between the plasma concentrations of tacrolimus and female sexual dysfunction has not yet been elucidated. The aim of this study was to determine the effect of tacrolimus use on sexual dysfunction of women after renal transplant.

Twenty-one female patients who successfully underwent transplant and were treated with tacrolimus were enrolled as the patient group, while 21 patients presented to the obstetrics and gynecology clinic for different reasons were included in the study as the control group. Harringtonine The Beck Depression Inventory, Beck Anxiety Inventory, and Female Sexual Function Index were applied. Plasma concentrations of tacrolimus were simultaneously measured in transplant recipients.

The scores of all scales did not differ among groups in terms of depression, anxiety, and sexual dysfunction. All transplant recipients had a plasma concentration of tacrolimus in the range of 3 to 7 ng/L. When the patients were compared by the scores of depression and anxiety scales, the drug levels showed no effect on the depression, anxiety, and female sexual functions.

Sexual dysfunction appears to be ameliorated in women because of the hormone levels after renal transplant at the end of the dialysis process, hence enhancing the quality of life. Normal plasma levels of tacrolimus, which is known to cause sexual dysfunction, could not change this result.

In this long-term study we compared kidney volume changes and function between living kidney donors and their corresponding recipients via magnetic resonance imaging after 3 to 8 years post transplantation.

For measurement of the kidney volume in magnetic resonance imaging images we used 3DSlicer. Statistical analysis was performed via t test and correlation.

A profound volume increase was observed in both transplanted and orthotopic kidney. The volume increase of the orthotopic kidneys was with 58 cm³ ± 23.8 cm³ SD (41%) greater than in the corresponding transplanted kidneys with 43 cm³ ± 36.9 cm³ SD (30%).

This study detected a persistent volume increase in both orthotopic and transplanted kidneys after donation. Neither significant increases of hypertension or proteinuria were observable or could be correlated to renal hypertrophy.
