Development of a Risk Score for Long-term Survival and MACCE After Coronary Artery Bypass Grafting Surgery.

OBJECTIVE: To develop risk scoring models predicting long-term survival and major adverse cardiovascular and cerebrovascular events (MACCE) including myocardial infarction and stroke after coronary artery bypass grafting (CABG). METHODS: All-consecutive 4,821 patients undergoing isolated CABG at Lankenau between 01/2005-07/2021 were included. MACCE was defined as all-cause mortality+myocardial infarction (MI)+stroke. Variable selection for both outcomes was obtained using a double selection logit Lasso with adaptive selection. Models performance was internally evaluated by calibration and accuracy using bootstrap cross-validation. Mortality and MACCE were compared among patients split into three groups based on the predicted risk scores for all-cause mortality and MACCE. An external validation of our database was performed with 665 patients from the University of Brescia, Italy. RESULTS: Pre-operative risk predictors were found to be predictors for all-cause mortality and MACCE. In addition, being of African American ethnicity is a significant predictor for MACCE after isolated CABG. The AUC which measures the discrimination of the models were 80.4%, 79.1%, 81.3%, and 79.2% for mortality at 1,2,3, and 5 years follow-up. The AUC for MACCE were 75%, 72.5%, 73,8%, and 72.7% at 1, 2, 3, and 5-years follow-up. For external validation, AUC for all-cause mortality and MACCE at 1, 2, 3, and 5 years was 73.7%, 70.8%, 68.7%, and 72.2% and 72.3%, 68.2%, 65.6%, 69.6%, respectively. CONCLUSIONS: The Advanced (AD) Coronary Risk Score for All-Cause Mortality and MACCE provide good discrimination of long-term mortality and MACCE after isolated CABG. External validation observed a more AUC's above 70%.

A Comparison of Emergency Room Visits and Hospital Admissions Between People with Prediabetes and Diabetes.

The purpose of this study was to characterize risk factors and groups at risk among people with diabetes and prediabetes for increased hospital utilization. Electronic health records for all people who visited the emergency department (ED) and had type II diabetes mellitus (PWD) or prediabetes (PWPD) were collected. ED use, hospital admissions, demographics, and clinical characteristics were compared between the groups. Multivariable logistic regression was used to compare the odds of ED high utilization (HU) (3+ visits per year) and hospital admissions between PWD and PWPD with interactions for socioeconomic status, race, marital status, and total comorbidities. PWD had higher mean ED visits per year compared with PWPD (1.5 vs. 1.2) and were more likely to be admitted (57.3% vs. 34.9%). PWD had higher odds of ED HU (2.1 [1.6, 2.7]) and hospital admissions (1.9 [1.6, 2.1]). Among PWD, Black, not married, and those with more than one comorbidity had the highest odds of ED HU. Among PWPD, those of low SES, Black, and divorced had the higher odds of ED HU. Hospital admissions were a risk for PWD and PWPD with increasing comorbidities. Early recognition and identification of prediabetes and clear criteria for diagnosis could reduce ED visits and hospital admissions.

Direct aortic cannulation versus femoral arterial cannulation for early outcomes in acute type A aortic dissection: A study-level meta-analysis.

PURPOSE: To investigate the impact of direct aortic cannulation (DAC) versus femoral arterial cannulation (FAC) on clinical outcomes of surgery for acute type A aortic dissection. METHODS: PubMed/MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials were searched until August 25, 2023, to conduct a meta-analysis. Primary endpoints of the study were operative mortality and postoperative stroke. Secondary endpoints were cardiopulmonary bypass time, myocardial ischemic time, hypothermic circulatory arrest time, temporary neurological dysfunction (TND), combined stroke and TND, re-exploration for bleeding, and need for renal replacement therapy. A random-effect model was used to estimate the pooled effect size, and a leave-one-out method was used for the primary endpoints for sensitivity analysis. RESULTS: 15 studies met our eligibility criteria, including a total of 7941 samples. Operative mortality was significantly lower in the DAC group with a pooled odds ratio (OR) of 0.72 [95% confidence interval (CI): 0.61-0.85)]. Incidence of postoperative stroke was also lower in the DAC group with a pooled OR of 0.79 (95% CI: 0.66-0.94). However, after excluding one study with the greatest weight, the difference became nonsignificant. DAC was also associated with a lower incidence of postoperative TND, and re-exploration for bleeding with a pooled OR of 0.52 (95% CI: 0.37-0.73), and 0.60 (95% CI: 0.47-0.77), respectively. CONCLUSIONS: This meta-analysis showed that patients who underwent ATAAD repair with DAC had a lower incidence of operative mortality, postoperative stroke, TND, and re-exploration for bleeding compared to those who underwent FAC.

Midterm Clinical Outcomes of Robotic-Assisted Reverse Hybrid Coronary Revascularization: A Single-Center Experience.

Outcomes of robotic-assisted reverse hybrid coronary revascularization (HCR) remain hindered. We aimed to analyze midterm clinical outcomes of robotic-assisted reverse HCR. All consecutive 285 patients who underwent reverse robotic-assisted HCR between September 2005 and July 2021 were included. Reverse HCR comprises percutaneous coronary intervention with stent implantation in non-left anterior descending (LAD) coronary arteries was performed within 30 days before robotic-assisted left internal thoracic artery (LITA) harvesting and LITA-to-LAD manual anastomosis through a 4-cm left minithoracotomy. Dual antiplatelet therapy was not interrupted in any patient. Preoperatively, mean age was 70.2 years (±11.2). Before surgery, 168 patients received 1 stent, 112 patients 2 stents, and 5 patients 3 stents. Intraoperatively, mean operating room time was 5.9 hours (±1); no case was converted to full sternotomy, whereas 9 patients (3.1%) received intraoperative blood product transfusions. Postoperatively, a small incidence of stroke, 1 (0.3%), reoperation for bleeding, 7 (2.4%), blood product transfusions, 48 (16.8%), and hospital stay (4.8 days) was observed. At 30-day follow-up, 1 patient (0.3%) underwent percutaneous coronary intervention with stent on a surgical LITA-LAD anastomosis owing to graft failure. Mean follow-up was 4.2 years. Reported midterm outcomes included all-cause death in 31 patients (10.9%), major adverse cardiovascular and cerebrovascular events in 102 of 285 (35.9%), nonfatal stroke in 2 of 285 (0.7%), myocardial infarction in 17 of 285 (5.9%), and repeat intervention in 50 of 285 patients (17.5%). This single-center study reports effective and safe clinical outcomes at midterm follow-up of reverse HCR procedures for treating multivessel coronary artery disease.

Long-term clinical outcomes of robotic-assisted surgical coronary artery revascularisation.

BACKGROUND: Patients who are not candidates for traditional coronary artery bypass grafting (CABG) and amenable only for percutaneous coronary intervention (PCI) with stents can receive the "gold standard" left internal thoracic artery (LITA) to left anterior descending artery (LAD) anastomosis through robotic-assisted CABG and PCI to non-LAD coronary targets. AIMS: We aimed to analyse clinical outcomes of robotic-assisted CABG. METHODS: A total of 2,280 consecutive patients who had undergone robotic-assisted CABG between May 2005 and June 2021 were included in our study. Robotic-assisted LITA harvest was followed by LITA-LAD manual anastomosis through a 4 cm left thoracotomy. Hybrid coronary intervention (HCR) consists of stent implantation in a non-LAD coronary artery performed within 7 days after robotic-assisted LITA-LAD. We performed a propensity-adjusted analysis comparison after dividing all robotic-assisted CABG patients into three time periods: 2005-2010, 615 patients; 2011-2016, 904 patients; and 2017-2021, 761 patients. RESULTS: The mean age increased from 64.5 years in the first time period to 65.8 years in the second time period to 68.1 years in the third (p<0.0001). Operative time was progressively reduced in the three periods (6.4; 6.2; 5.5 hours; p<0.001). The incidence of conversion to sternotomy remained similar for each period (1.8%; 1.7%; 1.5%; p=0.53). Thirty-day mortality in the three periods included 9 (1.4%), 9 (1.0%), and 7 (0.9%) patients, respectively (p=0.91), while 8 (0.3%) patients had PCI with stents in the entire group. The mean follow-up for the entire population was 4.2 years. At follow-up, the rates of all-cause death, major adverse cardiac and cerebrovascular events, non-fatal stroke, and repeat revascularisation with stents were significantly decreased from the first to the last period (pË0.0001). CONCLUSIONS: Robotic-assisted CABG and HCR provide good long-term outcomes in patients who are not candidates for conventional CABG.

Robotic-Assisted Versus Traditional Full-Sternotomy Coronary Artery Bypass Grafting Procedures: A Propensity-Matched Analysis of Hospital Costs.

We aim to compare hospital costs of robotic-assisted coronary artery bypass grafting (CABG) versus conventional CABG. All consecutive 1,173 patients who underwent conventional and robotic-assisted CABG between January 2018 and June 2021 were included. After propensity-matching, 267 patients in each group (robotic-assisted vs conventional) were included in the study. Patient selection for each group was decided by a treating surgeon with a heart team based on clinical factors. Syntax score was not assessed. Total costs (direct + indirect hospital costs) of patients who underwent robotic-assisted and conventional CABG were compared. Direct cost expenses included surgical operating time, hospital stay, surgical implants and supplies, catheterization laboratory, pharmacy, radiology and ultrasound imaging, blood bank, cardiology, and so on. Indirect cost expenses included general administration medical records, and so on. Using the propensity-matched groups (n = 267), we summed the total cost by year. Results for 267 propensity-matched patients (each group) evidenced that total conventional CABG costs were $9.5 million (average of $35,580/patient), whereas robotic-assisted CABG costs were $5 million ($18,726/patient). Therefore, the differences between robotic-assisted and conventional CABG costs were $4.5 million ($16,853/patient), favoring robotic-assisted over conventional CABG. Differences in direct and indirect costs were $2.2 million and $1.8 million, respectively. When the cost of the Da Vinci robot was added ($1,200,000), the total cost was $3.3 million ($12,359 × patient) lower in the robotic-assisted CABG group. Multivariate analysis showed that, mainly, the shorter hospital length of stay (7 vs 5 days) accounts for the reduced costs observed in the robotic-assisted CABG group. In conclusion, in a mature practice, robotic-assisted CABG decreases hospital length of stay, leading to reduced hospital costs compared with conventional CABG.

Clinical and Echocardiographic Outcomes of Patients Undergoing Transcatheter Edge-to-Edge Repair for Functional vs Degenerative Mitral Valve Regurgitation.

To analyze clinical and echocardiographic outcomes after transcatheter edge-to-edge repair (TEER) with mitral valve clip device (MitraClip-TM) for functional vs degenerative mitral valve regurgitation (MR). All consecutive 185 patients undergoing TEER between January 2019 and March 2023 were included in the study. A propensity-adjusted analysis investigated differences among functional vs degenerative MR mechanism groups. Preoperatively, functional vs degenerative MR included 43 vs 142 patients, respectively. Mean ejection fraction (EF) values were 37% vs 57.8%, mean STS-PROM risk score was 7% vs 4% while patients with severe MR included 29 (67.4%) vs 129 (90.9%) patients, respectively. Postoperatively, functional MR patients experienced a higher incidence of prolonged postoperative length of stay (LOS), reduced creatinine clearance, and EF<50% compared to the degenerative MR group. Mean EF was 35.9% vs 56.2% (P < 0.0001) and 1 (2.3%) vs 16 (11.3%) patients had residual severe MR (P = 0.01) in functional vs degenerative MR groups, respectively. At 30-days follow-up, all-cause death incidence was 1 (2.3%) vs 3 (2.1%) patients in functional vs degenerative MR, respectively (P = 0.9). At a mean of 1.6-years follow-up, all-cause death (P = 0.01), major adverse cardiovascular and cerebrovascular events (MACCE) (P = 0.02), cardiac death (P = 0.01) and hazard ratio for all-cause death higher in functional vs degenerative MR group. Mean EF was 39.7% vs 56% (P < 0.001) while residual severe MR was 4 (9.3%) vs 34 (24.5%) (P = 0.1) in functional vs degenerative MR groups, respectively. TEER with MitraClip device showed a higher incidence of all-cause death, cardiac death, and MACCE at follow-up for functional compared to degenerative MR after TEER.

Long-term prognosis in patients undergoing redo-isolated aortic valve replacement.

Aim: To evaluate clinical outcomes after redo aortic valve replacement (AVR) with sutured valves, versus valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), versus sutureless valves. Methods: We identified 113 consecutive patients undergoing redo AVR with either ViV-TAVR, redo-sutured and redo-sutureless valves between August 2010 to March 2020. Heart-team made the decision whether patient should undergo redo-sutureless versus ViV-TAVR, versus redo-sutured AVR. Results: Preoperatively, redo-sutured (n = 57), ViV-TAVR (n = 31) and redo-sutureless (n = 25) patients were compared. Postoperatively, after propensity-adjustment analysis, the redo surgical aortic valve replacement group had a higher incidence of new postoperative atrial fibrillation (POAF; p = 0.04) compared with redo-sutureless group. Follow-up outcomes analysis did not show differences among groups. Conclusion: Patients undergoing redo-sutureless AVR experienced a higher incidence of POAF compared with patients undergoing redo-sutured.

Association Between Lack of Access to a Neighborhood Park and High Blood Pressure in the Philadelphia Metropolitan Area.

INTRODUCTION: Studies have shown a lower risk of high blood pressure (HBP) among people who live near parks; however, little information exists on how feeling safe and comfortable visiting the park affects blood pressure. We identified associations between neighborhood park access, comfort visiting a park, and HBP to understand how these factors may contribute to disparities in HBP prevalence. METHODS: The 2018 Southeastern Pennsylvania Household Health Survey of 3,600 residents in the Philadelphia metropolitan area asked if respondents had ever been told they had HBP and whether they had a neighborhood park or outdoor space that they were comfortable visiting during the day. To assess the association between park access and HBP, we built multilevel logistic models to account for variation in HBP by zip code. We examined the effect modification of perceptions of park access (having a neighborhood park, not having a neighborhood park, or having a neighborhood park but not comfortable visiting it) and HBP by race, education, and poverty status. RESULTS: Both not having a neighborhood park and having a park but not feeling comfortable visiting it were associated with higher unadjusted odds of HBP, 70% and 90%, respectively, compared with having a neighborhood park. Adjusted odds ratios for the lack-of-park responses remained significant (no neighborhood park, adjusted odds ratio [aOR] = 1.4; 95% CI, 1.1-1.7; neighborhood park but not comfortable visiting, aOR = 1.4; 95% CI, 1.03-2.0). A significant gradient was observed for Black respondents compared with White respondents with odds of HBP increasing by perceptions of park access (aOR = 1.95 for people with a park; aOR = 2.69 for those with no park; aOR = 3.5 for people with a park that they are not comfortable visiting). CONCLUSION: Even accounting for other risk factors for HBP, not having a neighborhood park or not feeling comfortable visiting one may influence individual HBP. Neighborhood factors that deter park access may contribute to racial disparities in HBP.

Overall Survival and Associations of Insurance Status Among Hispanic Men With High-Risk Prostate Cancer.

Objectives Our objectives were to (1) determine the association between ethnicity and high-risk prostate cancer (PCa) survival and (2) determine whether this association is modified by insurance status. Methods We performed a retrospective review of the National Cancer Database (NCDB) from 2004 to 2017 of non-Hispanic White (NHW), Hispanic White (HW), or Black men with high-risk PCa. A multivariate Cox regression model was built to test the association between overall survival (OS) and race/ethnicity, insurance status, and their interaction, controlling for various socioeconomic and disease-specific variables. Results A total of 94,708 men with high-risk PCa were included in the analysis. Both HW and Black men had lower socioeconomic status characteristics and lower rates of private insurance. Race/ethnicity was significantly associated with OS in the adjusted analysis. Only Medicare demonstrated significantly worse OS. NHW (covariate-adjusted hazard ratio (aHR): 1.83, 95% CI: 1.45-2.32) and Black (aHR: 1.71, 05% CI: 1.34-2.19) men demonstrated significantly worse survival when compared to HW men. Subgroup analysis demonstrated significant differences occurring among HW men with private insurance/managed care when compared to those not insured, Medicaid, Medicare, and other government insurance types. Conclusion Despite socioeconomic and demographic disadvantages, HW men demonstrate improved OS compared to NHW men. Furthermore, HW men demonstrated improved OS compared to NHW men within nearly each insurance status type. This finding is likely the result of a complex multifactorial web and as such serves as an interesting hypothesis-generating study.

Spinal versus general anesthesia: Comparing outcomes in pediatric patients undergoing urologic procedures.

INTRODUCTION: Available literature comparing spinal anesthesia (SA) to general anesthesia (GA) in the pediatric population describes multiple benefits in appropriately selected patients including cost reduction, lower incidence of complications, and shorter operative times. In patients undergoing urologic procedures, data are sparse. OBJECTIVE: Our goal was to expand on the paucity of existing urologic literature as SA appears to be uniquely suited for a substantial number of its common pediatric procedures. METHODS: Within a single institution, patients who had a urologic procedure performed under SA between May 2019 and July 2021 and were less than 18 months old were compared with a matched cohort of patients who had GA. The SA and GA groups were compared by two-sample t-tests, chi-square test for independence, and Fisher's exact test. RESULTS: There were a total of 184 SA and 202 GA patients. There was no significant difference in the demographics except that SA patients were younger and weighed less than GA patients. The patients in the SA group needed less opioids both during the surgery (0% vs 26.1% p N/A) and in the immediate postoperative period when compared with GA patients (0% vs 18.2% p N/A). The patients who had SA had fewer complications necessitating PICU admission, or cancellation of surgery (0% vs 6.8% p = 0.03). Total anesthesia and emergence time were lower for SA patients (41 vs 50.2 p = 0.001 & 3.4 vs 6.1 p = 0.001). Both surgery and total OR time were not different between the groups (37.6 vs 35.5 p = 0.35 and 56.3 vs 54.4 p = 0.49). Overall, raw material cost was also found to be lower per procedure in the SA group vs the GA group ($8.90 vs $38.8: 77% reduction). Adjusted total mean costs for the surgery were not different between groups. The reduction in opioid use postoperatively also suggests reduced cost in the management of postoperative pain in the SA group. DISCUSSION: Total anesthesia time, opioid use, and serious complications were all significantly lower in the SA group. We did not find significant difference in total surgery cost between two groups. However, patients who had SA had better pain control and needed less rescue analgesics in the immediate postoperative period. No patients in either group were sent home with opioids. CONCLUSION: Spinal anesthesia was found to be an equally effective and appropriate alternative to GA with many proposed benefits for common pediatric urologic procedures. With further research, SA may prove to be a safer alternative in patients at risk for complications related to GA general anesthesia while also offering a cost benefit.

African American Males Have More Distress During Cancer Treatment Than White Males.

African American (AA) males have a higher incidence and mortality rate for some cancers than other races and sexes, which could be associated with distress during treatment, medical mistrust, and health disparities. We hypothesize distress in AA males during treatment is higher than in other races and sexes. We assessed effect modification of moderate to severe (≥ 4) distress scores during cancer treatment by race and sex, age, and socioeconomic status (SES). National Comprehensive Cancer Network's distress thermometer (scale 0-10) and characteristics for 770 cancer patients were collected from a Philadelphia hospital. Variables included age, sex, race, smoking status, marital status, SES, comorbidities, mental health, period before and during COVID-19, cancer diagnosis, and stage. Descriptive statistics, chi-square tests, and t-tests were used to compare AA and White patients. Effect modification of ≥ 4 distress by race and sex, age, and SES were analyzed by logistic regression. A p value of ≤ .05 was significant, and 95% confidence intervals (CIs) were reported. On average, AA patients had a non-significant, higher distress score (4.53, SD = 3.0) than White patients (4.22, SD = 2.9) (p = .196). The adjusted odds ratio of ≥4 distress was 2.8 (95% CI [1.4, 5.7]) for AA males compared with White males. There was no significant difference between White and AA females, race and age, or race and SES. There was an effect modification of ≥4 distress by race and sex. AA males in cancer treatment had higher odds of ≥4 distress compared with White males.

Risk factors for heightened COVID-19-Related anxiety among breast cancer patients.

BACKGROUND: The COVID-19 pandemic has disrupted medical care, increased isolation, and exacerbated anxiety in breast cancer patients. Since March 2020, Breastcancer.org experienced a sustained surge in requested pandemic-related information and support. To characterize the pandemic-related experiences of breast cancer patients, we surveyed the Breastcancer.org Community early in the COVID-19 era. METHODS: Breastcancer.org Community members were invited to complete an online questionnaire regarding their experience during the pandemic. Self-reported data on demographics, comorbidities, care disruptions, anxiety, coping ability, telemedicine use, and satisfaction with care were collected. Results were analyzed using Stata 16.0 (Stata Corp., Inc). RESULTS: Included were 568 current and previous breast cancer patients, primarily with U.S. residence. Overall, 43.8% reported at least one comorbidity associated with severe COVID-19 illness and 61.9% experienced care delays. Moderate to extreme anxiety about contracting COVID-19 was reported by 36.5%, increasing with number of comorbidities (33.0% vs. 55.4%, p = 0.021), current breast cancer diagnosis (30.4% vs. 42.5%, p = 0.011), and poorer coping ability (15.5% vs. 53.9%, p < 0.0001). Moderate to extreme anxiety about cancer care disruptions was reported by 29.1%, increasing with current breast cancer diagnosis (19.1% vs. 38.9%, p < 0.0001), actual delayed care (18.9% vs. 35.3%, p < 0.0001), and poorer coping ability (13.1% vs. 57.7%, p < 0.0001). Most utilized telehealth and found it helpful, but also expressed increased anxiety and subjectively expressed that these were less preferable. CONCLUSION: Early in the COVID-19 pandemic, anxiety was reported by a large proportion of breast cancer patients, with increased prevalence in those with risk factors. Attention to mental health is critical, as emotional distress not only harms quality of life but may also compromise outcomes.

Outcomes of Abbreviated MRI (Ab-MRI) for Women of any Breast Cancer Risk and Breast Density in a Community Academic Setting.

BACKGROUND: Abbreviated magnetic resonance imaging (Ab-MRI) has been evaluated for elevated breast cancer risk or dense breasts but has not been evaluated across all risk profiles. METHODS: Patients selected underwent Ab-MRI from February 2020 to September 2021. Women were older than aged 30 years, up to date with screening mammography, and paid $299 cash. RESULTS: A total of 93 patients were identified with a mean age of 52 years; 92.5% were Caucasian, 0% black, and 97.9% were from high socioeconomic status. Mean Gail score was 14.2, and 83.3% had a lifetime risk of breast cancer <20%. Reasons for Ab-MRI: dense breasts (36.6%); family history (24.7%); palpable mass (12.9%). Providers ordering: OBGYN (49.5%); breast surgeon (39.1%); primary care (6.6%). Thirteen biopsies (14%) detected one breast cancer. 31.1% had a change in follow-up screening: 58.6% 6-month MRI, 20.7% 6-month mammogram, and 10.3% 6-month ultrasound. Negative predictive value was 100% (95% confidence interval [CI]: 95-100%, p < 0.0001). Sensitivity was 100% (95% CI: 2.5-100%, p < 0.0001), and specificity was 87% (95% CI: 78.3-93.1%, p < 0.0001) compared with 77.6% and 98.8% for mammography. Only one cancer was detected: cost of $27,807 plus cost of 13 MRI or ultrasound (US)-guided biopsies and additional follow-up imaging. Historically 20% of abnormalities detected on full MRI are malignant; however, 7.7% of ab-MRI abnormalities were malignant CONCLUSIONS: One third of women were recommended a change in follow-up, which predominantly included a 6-month MRI. Ab-MRI may introduce average risk women to unnecessary follow-up and increased biopsies with a lower cancer detection rate. Ab-MRI should be evaluated closely before implementation.
