Uptake of Cervical Cancer Screening Among Female Patients Using a Mobile Medical Clinic.

INTRODUCTION: Although cervical cancer causes morbidity, it can be prevented if diagnosed early; previous research has shown lower rates of screening in patients with health-related social needs by self-report data. This study assessed cervical cancer screening uptake among female patients with health-related social needs who access care through a community-based mobile medical clinic. METHODS: A retrospective cohort was developed of all cis-female patients aged 21-65 years who sought care at the mobile medical clinic between January 1, 2016 and December 31, 2019, and their medical data were captured from the electronic health record. Bivariate and multivariate logistic regression (performed in 2022/2023) were used to investigate correlates of ever having received cervical cancer screening and of being up to date with cervical cancer screening. RESULTS: Less than half of the 1,455 patient cohort had ever undergone Pap testing. In the multivariate model, ever having received cervical cancer screening was directly associated with being Hispanic or Black, living with HIV, and having received human papillomavirus vaccination. People who currently smoke showed significantly lower odds of ever having had cervical cancer screening than people who have never smoked. Patients who were single or had other marital status had lower adjusted odds of being up to date as well as those with a substance use history and those with unstable housing. CONCLUSIONS: Cervical cancer screening rates in this community-based mobile medical clinic model were low, highlighting a need for increased attention to screening in this high-risk population. Mobile medical clinics have increased screening uptake internationally, and this model could be adopted domestically to promote screening to patients who access health care in various settings.

Outcomes of patients with advanced liver disease undergoing cardiac surgery.

Objective: Liver disease (LD) is considered a risk factor for inferior outcomes in general and cardiac surgery, yet current cardiac surgery risk estimators exclude LD, and literature on the topic remains scant. We sought to evaluate whether the presence of advanced LD is associated with inferior outcomes following cardiac surgery. Methods: This single-center, retrospective, observational study included 285 patients diagnosed with LD who underwent cardiac surgery in 2010 to 2020. The cohort contained 3 groups, Child-Turcotte-Pugh (CTP) class A (n = 219), CTP early-class B (n = 34), and CTP advanced-class B (n = 32). A model for end-stage liver disease score of 12.7 points (determined using a receiver-operating characteristic curve analysis on 30-day mortality) dichotomized class B into early- and advanced-groups. Univariate and multivariate logistic regression analyses were performed to identify predictors of 30-day mortality. Results: Patients in CTP advanced-class B had the longest length of stay (14 days), highest incidence of prolonged ventilation (46.9%), renal failure (21.9%), 30-day mortality (18.8%), and in-hospital mortality (18.8%). Incidence of ≥1 postoperative complication was higher in CTP advanced-class B (59.4%), compared with CTP class A (37.9%) and CTP early-class B (38.2%). Multivariate logistic regression analysis demonstrated that female sex (odds ratio, 3.01; 95% CI, 1.07-8.77; P = .037) and peripheral vascular disease (odds ratio, 4.01; 95% CI, 1.33-12.2; P = .013) were independent predictors of 30-day mortality in patients with advanced LD. Conclusions: Severity of LD influences perioperative outcomes following cardiac surgery. Our data suggest that patients in CTP class A and selected patients in CTP class B (model for end-stage liver disease score <12.7) can undergo surgery with acceptable risk.

Long-term risk of arch complications in Loeys Dietz syndrome patients undergoing proximal ascending aortic replacement.

PURPOSE: Loeys-Dietz syndrome (LDS) is a rare connective tissue disorder. In LDS patients with normal arch morphology, whether the arch should be prophylactically replaced at the time of proximal aortic replacement remains unknown. We evaluated the risk of long-term arch complications in genetically confirmed LDS patients who underwent proximal ascending aortic replacement. METHODS: We retrospectively reviewed the records of patients with LDS who have been followed at our institution between 1994 and 2020. Patients were only included if whole exome genetic testing confirmed a mutation in an LDS-causing gene (TGFBR1, TGFBR2, SMAD3, TGFB2, or TGFB3). Mutations were categorized as pathogenic, benign, or of unknown significance. We collected demographic information, aortic dimensions, comorbidities, mortality, and operative course from patients' charts. Descriptive statistics and freedom from reoperation plots were generated. RESULTS: Of the 18 patients with a mutation in an LDS-causing gene, 15 had known pathogenic variants, two had mutations of unknown significance, and one had a benign genetic variant. For the 15 patients with confirmed pathogenic variants of LDS the median follow-up duration was 5 years (interquartile range [IQR]: 4-8). Eleven patients underwent ascending aortic replacements (AAR) ± aortic valve replacement. Two patients required an additional operation; one required arch and staged elephant trunk for a dissection 18 years post-AAR and the other patient required an isolated descending aortic replacement for dissection 5 years post-AAR. Among patients who underwent surgery, the median ascending aortic diameter at intervention was 5.0 cm (IQR: 4.3-5.3). There was no surgical or late follow-up mortality observed for any of the 18 patients in the study. CONCLUSION: LDS patients who underwent proximal aortic replacement appeared to have low long-term risk of arch complications. While our study is somewhat limited by its sample size and follow-up duration, it suggests that routine prophylactic total arch replacement may not be warranted in LDS patients with nonaneurysmal aortic arches.

Aortic valve neocuspidization: Frequently asked technical questions.

Since the first description by Professor Ozaki in 2011, more than 5500 aortic valve neocuspidization procedures have been performed worldwide, with promising short- and mid-term outcomes. We here report the nuances required to master this highly reproducible, standardized technique for the treatment of aortic valve disease.

Socioeconomic disparities in surveillance and follow-up of patients with thoracic aortic aneurysm.

BACKGROUND: Thoracic aortic aneurysm (TAA) is a significant risk factor for aortic dissection and rupture. Guidelines recommend referral of patients to a cardiovascular specialist for periodic surveillance imaging with surgical intervention determined primarily by aneurysm size. We investigated the association between socioeconomic status (SES) and surveillance practices in patients with ascending aortic aneurysms. METHODS: We retrospectively reviewed records of 465 consecutive patients diagnosed between 2013 and 2016 with ascending aortic aneurysm ≥4 cm on computed tomography scans. Primary outcomes were clinical follow-up with a cardiovascular specialist and aortic surveillance imaging within 2 years following index scan. We stratified patients into quartiles using the area deprivation index (ADI), a validated percentile measure of 17 variables characterizing SES at the census block group level. Competing risks analysis was used to determine interquartile differences in risk of death before follow up with a cardiovascular specialist. RESULTS: Lower SES was associated with significantly lower rates of surveillance imaging and referral to a cardiovascular specialist. On competing risks regression, the ADI quartile with lowest SES had lower hazard of follow-up with a cardiologist or cardiac surgeon before death (hazard ratio: 0.46 [0.34, 0.62], p < .001). Though there were no differences in aneurysm size at time of surgical repair, patients in the lowest socioeconomic quartile were more frequently symptomatic at surgery than other quartiles (92% vs. 23%-38%, p < .001). CONCLUSION: Patients with lower SES receive less timely follow-up imaging and specialist referral for TAAs, resulting in surgical intervention only when alarming symptoms are already present.

Patterns of Surveillance Imaging for Incidentally Detected Ascending Aortic Aneurysms.

BACKGROUND: Ascending aortic aneurysms (AsAA) remain a silent killer for which timely intervention and surveillance intervals are critical. Despite this, little is known about the follow-up care patients receive after incidental detection of an AsAA. We examined the pattern of surveillance and follow-up care for these high-risk patients. METHODS: We identified patients at our institution with incidentally detected AsAAs (≥37 mm) between 2013 and 2016. We collected information on patients' aneurysms and clinical follow-up. Logistic regression models related aneurysm size and demographics to whether patients received follow-up imaging or referral. RESULTS: From 2013 to 2016, 261 patients were identified to have incidentally detected AsAAs among the 21,336 computed tomography scans performed at our institution. The median aneurysm size was 4.2 cm (interquartile range, 4 to 4.4). Only 18 (6.9%) of the identified patients were referred to a cardiac surgeon for evaluation, and only 37.9% of the identified patients had a follow-up chest computed tomography scan within 1 year of detection; 34% had an echocardiogram. The median follow-up duration for the study was 5 years. Logistic regression models showed that aneurysm size and family history were significant predictors of whether a patient was referred to a cardiac surgeon (odds ratio 10.34; 95% confidence interval, 2.3 to 47.9), but not whether the patients received follow-up imaging. CONCLUSIONS: Among 261 patients with incidentally detected AsAAs, only a third received any follow-up imaging within 1 year after detection, with very low clinical penetrance for expert referral. Surveillance of this high-risk patient population appears insufficient and may require standardization.

Robotic, totally endoscopic atrial septal defect repair.

Atrial septal defect accounts for 10-15% of congenital heart disease cases. Small-diameter atrial septal defects diagnosed during infancy or early adulthood are prone to spontaneous closure, whereas uncorrected, persistent moderate or large atrial septal defects can induce left-to-right shunting, which causes volume overload, heart failure, atrial arrhythmia, and/or pulmonary hypertension starting between the third and fourth decades of life. We describe in detail our technique for totally endoscopic, robotic-assisted atrial septal defect repair.

Educational intervention against biological racism.

INTRODUCTION: Biological race, the fallacy that racial health disparities reflect differences in human biology, exerts undue influence on medicine. Interventions that teach against this myth are largely absent from required medical curricula. Here, we describe and present student and facilitator evaluations of an educational intervention, organised around Dorothy Roberts' book Fatal Invention: How Science, Politics, and Big Business Re-Create Race in the Twenty-First Century that included a discussion of preselected chapters from Fatal Invention, case studies illustrating strategies to prevent the misuse of race in medicine and a question-and-answer session with Dorothy Roberts. METHODS: Online feedback surveys were distributed to students and facilitators to capture their general perceptions of the session, how well it satisfied its objectives and the pre-session training materials provided to facilitators. Quantitative measures were analysed using descriptive statistics, and qualitative responses were evaluated using thematic analysis. RESULTS: Student and facilitator surveys garnered response rates of 59.8% (61/102) and 75% (30/40), respectively, and most expressed satisfaction with the session. Students felt more prepared to address the misuse of race in clinical contexts than in pre-clinical contexts (90.16% vs. 77.05%) and among peers than among superiors (95.08% vs. 72.13%) (p < 0.05). Some students (31.15%) felt that their small group facilitators were unprepared to address microaggressions. DISCUSSION: Our survey responses suggest that this intervention was effective in teaching against biological racism and equipped students with tools to address the misuse of race, particularly in clinical contexts. Future iterations should highlight strategies to confront biological racism in pre-clinical contexts and among superiors.
