A functional cellular framework for sex and estrous cycle-dependent gene expression and behavior.

Sex hormones exert a profound influence on gendered behaviors. How individual sex hormone-responsive neuronal populations regulate diverse sex-typical behaviors is unclear. We performed orthogonal, genetically targeted sequencing of four estrogen receptor 1-expressing (Esr1+) populations and identified 1,415 genes expressed differentially between sexes or estrous states. Unique subsets of these genes were distributed across all 137 transcriptomically defined Esr1+ cell types, including estrous stage-specific ones, that comprise the four populations. We used differentially expressed genes labeling single Esr1+ cell types as entry points to functionally characterize two such cell types, BNSTprTac1/Esr1 and VMHvlCckar/Esr1. We observed that these two cell types, but not the other Esr1+ cell types in these populations, are essential for sex recognition in males and mating in females, respectively. Furthermore, VMHvlCckar/Esr1 cell type projections are distinct from those of other VMHvlEsr1 cell types. Together, projection and functional specialization of dimorphic cell types enables sex hormone-responsive populations to regulate diverse social behaviors.

Safety and learning curve of percutaneous axillary artery access for complex endovascular aortic procedures.

BACKGROUND: Percutaneous axillary artery access is increasingly used for large-bore access during interventional vascular and cardiac procedures. The aim of this study was to evaluate the safety and learning curve of percutaneous axillary artery access in patients undergoing complex endovascular aortic repair (fenestrated and branched endovascular aneurysm repair [FBEVAR]) requiring large-bore upper extremity access and to discuss best practices for technique and complication management. METHODS: One-hundred forty-six patients undergoing large-bore percutaneous axillary artery access during FBEVAR in a prospective, nonrandomized, Investigational Device Exemption study between September 2017 and January 2023 were analyzed. Ultrasound guidance and micropuncture were used to access the second portion of the axillary artery and 2 Perclose Proglide or Prostyle devices (Abbott Vascular) were predeployed before the insertion of the large-bore sheath. Completion angiography was performed in all patients to verify hemostatic closure. Axillary artery patency was also assessed on follow-up computed tomography angiography. Patient-related, procedural, and postoperative variables were collected and analyzed. RESULTS: One-hundred forty-five patients underwent successful percutaneous axillary artery access; 1 patient failed axillary access and alternative access was established. The left axillary artery was accessed in 115 patients (79%), and the right axillary artery was accessed in 30 patients (21%). The largest profile sheath was 14 F in 4 patients (2.8%), 12F in 133 patients (91.7%), and 8F in 8 patients (5.5%). Ten patients (6.9%) required covered stent placement (Viabahn, W. L. Gore & Associates) for failure to achieve hemostasis; there were no conversions to open surgical repair. Additional adverse events included transient upper extremity weakness in two patients (1.3%) and transient upper extremity paresthesias in two patients (1.3%). Three patients (2%) suffered postoperative strokes, including one unrelated hemorrhagic stroke and two possibly access-related embolic strokes. On follow-up, axillary artery patency was 100%. There was a trend toward decreased closure failure over time, with seven patients (10%) in the early cohort and three (4%) in the late cohort. There was a significant negative correlation between the cumulative complication rate and the cumulative experience. CONCLUSIONS: Large-bore percutaneous axillary artery access provides safe upper extremity large-bore access during FBEVAR, achieving successful closure in >90% of patients with a low incidence of access-related complications. There was a trend toward better closure rates with increasing experience, suggesting a learning curve effect. Application of best practices including ultrasound guidance and angiography may ensure safe application of the technique of percutaneous large-bore axillary artery access.

The association between sex and outcomes after thoracic endovascular repair for acute type B aortic dissection.

OBJECTIVE: Prior literature has found worse outcomes for female patients after endovascular repair of abdominal aortic aneurysm and mixed findings after thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysm. However, the influence of sex on outcomes after TEVAR for acute type B aortic dissection (aTBAD) is not fully elucidated. METHODS: We identified patients who underwent TEVAR for aTBAD (<30 days) in the Vascular Quality Initiative from 2014 to 2022. We excluded patients with an entry tear or stent seal within the ascending aorta or aortic arch and patients with an unknown proximal tear location. Included patients were stratified by biological sex, and we analyzed perioperative outcomes and 5-year mortality with multivariable logistic regression and Cox regression analysis, respectively. Furthermore, we analyzed adjusted variables for interaction with female sex. RESULTS: We included 1626 patients, 33% of whom were female. At presentation, female patients were significantly older (65 [interquartile range: 54, 75] years vs 56 [interquartile range: 49, 68] years; P = .01). Regarding indications for repair, female patients had higher rates of pain (85% vs 80%; P = .02) and lower rates of malperfusion (23% vs 35%; P < .001), specifically mesenteric, renal, and lower limb malperfusion. Female patients had a lower proportion of proximal repairs in zone 2 (39% vs 48%; P < .01). After TEVAR for aTBAD, female sex was associated with comparable odds of perioperative mortality to males (8.1 vs 9.2%; adjusted odds ratio [aOR]: 0.79 [95% confidence interval (CI): 0.51-1.20]). Regarding perioperative complications, female sex was associated with lower odds for cardiac complications (2.3% vs 4.7%; aOR: 0.52 [95% CI: 0.26-0.97]), but all other complications were comparable between sexes. Compared with male sex, female sex was associated with similar risk for 5-year mortality (26% vs 23%; adjusted hazard ratio: 1.01 [95% CI: 0.77-1.32]). On testing variables for interaction with sex, female sex was associated with lower perioperative and 5-year mortality at older ages relative to males (aOR: 0.96 [0.93-0.99] | adjusted hazard ratio: 0.97 [0.95-0.99]) and higher odds of perioperative mortality when mesenteric malperfusion was present (OR: 2.71 [1.04-6.96]). CONCLUSIONS: Female patients were older, less likely to have complicated dissection, and had more distal proximal landing zones. After TEVAR for aTBAD, female sex was associated with similar perioperative and 5-year mortality to male sex, but lower odds of in-hospital cardiac complications. Interaction analysis showed that females were at additional risk for perioperative mortality when mesenteric ischemia was present. These data suggest that TEVAR for aTBAD overall has a similar safety profile in females as it does for males.

Predictors of prolonged length of stay after elective carotid revascularization.

OBJECTIVE: Postoperative day-one discharge is used as a quality-of-care indicator after carotid revascularization. This study identifies predictors of prolonged length of stay (pLOS), defined as a postprocedural LOS of >1 day, after elective carotid revascularization. METHODS: Patients undergoing carotid endarterectomy (CEA), transcarotid artery revascularization (TCAR), and transfemoral carotid artery stenting (TFCAS) in the Vascular Quality Initiative between 2016 and 2022 were included in this analysis. Multivariable logistic regression analysis was used to identify predictors of pLOS, defined as a postprocedural LOS of >1 day, after each procedure. RESULTS: A total of 118,625 elective cases were included. pLOS was observed in nearly 23.2% of patients undergoing carotid revascularization. Major adverse events, including neurological, cardiac, infectious, and bleeding complications, occurred in 5.2% of patients and were the most significant contributor to pLOS after the three procedures. Age, female sex, non-White race, insurance status, high comorbidity index, prior ipsilateral CEA, non-ambulatory status, symptomatic presentation, surgeries occurring on Friday, and postoperative hypo- or hypertension were significantly associated with pLOS across all three procedures. For CEA, additional predictors included contralateral carotid artery occlusion, preoperative use of dual antiplatelets and anticoagulation, low physician volume (<11 cases/year), and drain use. For TCAR, preoperative anticoagulation use, low physician case volume (<6 cases/year), no protamine use, and post-stent dilatation intraoperatively were associated with pLOS. One-year analysis showed a significant association between pLOS and increased mortality for all three procedures; CEA (hazard ratio [HR],1.64; 95% confidence interval [CI], 1.49-1.82), TCAR (HR,1.56; 95% CI, 1.35-1.80), and TFCAS (HR, 1.33; 95%CI, 1.08-1.64) (all P < .05). CONCLUSIONS: A postoperative LOS of more than 1 day is not uncommon after carotid revascularization. Procedure-related complications are the most common drivers of pLOS. Identifying patients who are risk for pLOS highlights quality improvement strategies that can optimize short and 1-year outcomes of patients undergoing carotid revascularization.

Comparison of open and endovascular left subclavian artery revascularization for zone 2 thoracic endovascular aortic repair.

OBJECTIVE: In patients undergoing elective thoracic endovascular aortic repair (TEVAR) and left subclavian artery (LSA) coverage, routine preoperative LSA revascularization is recommended. However, in the current endovascular era, the optimal surgical approach is debated. We compared baseline characteristics, procedural details, and perioperative outcomes of patients undergoing open or endovascular LSA revascularization in the setting of TEVAR. METHODS: Adult patients undergoing TEVAR with zone 2 proximal landing and LSA revascularization between 2013 and 2023 were identified in the Vascular Quality Initiative. We excluded patients with traumatic aortic injury, aortic thrombus, or ruptured presentations, and stratified based on revascularization type (open vs any endovascular). Open LSA revascularization included surgical bypass or transposition. Endovascular LSA revascularization included single-branch, fenestration, or parallel stent grafting. Primary outcomes were stroke, spinal cord ischemia (SCI), and perioperative mortality (Pearson's χ2 test). Multivariable logistic regression was used to evaluate associations between revascularization type and primary outcomes. Secondarily, we studied other in-hospital complications and 5-year mortality (Kaplan-Meier, multivariable Cox regression). Sensitivity analyses were performed in patients undergoing concomitant LSA revascularization to TEVAR. RESULTS: Of 2489 patients, 1842 (74%) underwent open and 647 (26%) endovascular LSA revascularization. Demographics and comorbidities were similar between open and endovascular cohorts. Compared with open, endovascular revascularization had shorter procedure times (median, 135 minutes vs 174 minutes; P < .001), longer fluoroscopy times (median, 23 minutes vs 16 minutes; P < .001), lower estimated blood loss (median, 100 mL vs 123 mL; P < .001), and less preoperative spinal drain use (40% vs 49%; P < .001). Patients undergoing endovascular revascularization were more likely to present urgently (24% vs 19%) or emergently (7.4% vs 3.4%) (P < .001). Compared with open, endovascular patients experienced lower stroke rates (2.6% vs 4.8%; P = .026; adjusted odds ratio [aOR], 0.50 [95% confidence interval (CI), 0.25-0.90]), but had comparable SCI (2.9% vs 3.5%; P = .60; aOR, 0.64 [95% CI, 0.31-1.22]) and perioperative mortality (3.1% vs 3.3%; P = .94; aOR, 0.71 [95% CI, 0.34-1.37]). Compared with open, endovascular LSA revascularization had lower rates of overall composite in-hospital complications (20% vs 27%; P < .001; aOR, 0.64 [95% CI, 0.49-0.83]) and shorter overall hospital stay (7 vs 8 days; P < .001). After adjustment, 5-year mortality was similar among groups (adjusted hazard ratio, 0.85; 95% CI, 0.64-1.13). Sensitivity analyses supported the primary analysis with similar outcomes. CONCLUSIONS: In patients undergoing TEVAR starting in zone 2, endovascular LSA revascularization had lower rates of postoperative stroke and overall composite in-hospital complications, but similar SCI, perioperative mortality, and 5-year mortality rates compared with open LSA revascularization. Future comparative studies are needed to evaluate the mid- to long-term safety of endovascular LSA revascularization and assess differences between specific endovascular techniques.

Outcomes of carotid revascularization stratified by procedure in patients with an estimated glomerular filtration rate of <30 and dialysis patients.

OBJECTIVE: Renal failure is a predictor of adverse outcomes in carotid revascularization. There has been debate regarding the benefit of revascularization in patients with severe chronic kidney disease or on dialysis. METHODS: Patients in the Vascular Quality Initiative undergoing transcarotid artery revascularization (TCAR), transfemoral carotid artery stenting (tfCAS), or CEA between 2016 and 2023 with an estimated glomerular filtration rate (eGFR) of <30 mL/min/1.73 m2 or on dialysis were included. Patients were divided into cohorts based on procedure. Additional analyses were performed for patients on dialysis only and by symptomatology. Primary outcomes were perioperative stroke/death/myocardial infarction (MI) (SDM). Secondary outcomes included perioperative death, stroke, MI, cranial nerve injury, and stroke/death. Inverse probability of treatment weighting was performed based on treatment assignment to TCAR, tfCAS, and CEA patients and adjusted for demographics, comorbidities, and preoperative symptoms. The χ2 test and multivariable logistic regression analysis were used to evaluate the association of procedure with perioperative outcomes in the weighted cohort. Five-year survival was evaluated using Kaplan-Meier and weighted Cox regression. RESULTS: In the weighted cohort, 13,851 patients with an eGFR of <30 (2506 on dialysis) underwent TCAR (3639; 704 on dialysis), tfCAS (1975; 393 on dialysis), or CEA (8237; 1409 on dialysis) during the study period. Compared with TCAR, CEA had higher odds of SDM (2.8% vs 3.6%; adjusted odds ratio [aOR], 1.27; 95% confidence interval [CI], 1.00-1.61; P = .049), and MI (0.7% vs 1.5%; aOR, 2.00; 95% CI, 1.31-3.05; P = .001). Compared with TCAR, rates of SDM (2.8% vs 5.8%), stroke (1.2% vs 2.6%), and death (0.9% vs 2.4%) were all higher for tfCAS. In asymptomatic patients CEA patients had higher odds of MI (0.7% vs 1.3%; aOR, 1.85; 95% CI, 1.15-2.97; P = .011) and cranial nerve injury (0.3% vs 1.9%; aOR, 7.23; 95% CI, 3.28-15.9; P < .001). Like in the primary analysis, asymptomatic tfCAS patients demonstrated higher odds of death and stroke/death. Symptomatic CEA patients demonstrated no difference in stroke, death, or stroke/death. Although tfCAS patients demonstrated higher odds of death, stroke, MI, stroke/death, and SDM. In both groups, the 5-year survival was similar for TCAR and CEA (eGFR <30, 75.1% vs 74.2%; aHR, 1.06; P = .3) and lower for tfCAS (eGFR <30, 75.1% vs 70.4%; aHR, 1.44; P < .001). CONCLUSIONS: CEA and TCAR had similar odds of stroke and death and are both a reasonable choice in this population; however, TCAR may be better in patients with an increased risk of MI. Additionally, tfCAS patients were more likely to have worse outcomes after weighting for symptom status. Finally, although patients with a reduced eGFR have worse outcomes than their healthy peers, this analysis shows that the majority of patients survive long enough to benefit from the potential stroke risk reduction provided by all revascularization procedures.

Outcomes following carotid revascularization in patients with prior ipsilateral carotid artery stenting in the Vascular Quality Initiative.

OBJECTIVE: The outcomes of carotid revascularization in patients with prior carotid artery stenting (CAS) remain understudied. Prior research has not reported the outcomes after transcarotid artery revascularization (TCAR) in patients with previous CAS. In this study, we compared the peri-operative outcomes of TCAR, transfemoral CAS (tfCAS) and carotid endarterectomy (CEA) in patients with prior ipsilateral CAS using the Vascular Quality Iniatitive. METHODS: Using Vascular Quality Initiative data from 2016 to 2023, we identified patients who underwent TCAR, tfCAS, or CEA after prior ipsilateral CAS. We included covariates such as age, race, sex, body mass index, comorbidities (hypertension, diabetes, prior coronary artery disease, prior coronary artery bypass grafting/percutaneous coronary intervention, congestive heart failure, renal dysfunction, smoking, chronic obstructive pulmonary disease, and anemia), symptom status, urgency, ipsilateral stenosis, and contralateral occlusion into a regression model to compute propensity scores for treatment assignment. We then used the propensity scores for inverse probability weighting and weighted logistic regression to compare in-hospital stroke, in-hospital death, stroke/death, postoperative myocardial infarction (MI), stroke/death/MI, 30-day mortality, and cranial nerve injury (CNI) after TCAR, tfCAS, and CEA. We also analyzed trends in the proportions of patients undergoing the three revascularization procedures over time using Cochrane-Armitage trend testing. RESULTS: We identified 2137 patients undergoing revascularization after prior ipsilateral carotid stenting: 668 TCAR patients (31%), 1128 tfCAS patients (53%), and 341 CEA patients (16%). In asymptomatic patients, TCAR was associated with a lower yet not statistically significant in-hospital stroke/death than tfCAS (TCAR vs tfCAS: 0.7% vs 2.0%; adjusted odds ratio [aOR], 0.33; 95% confidence interval [CI], 0.11-1.05; P = .06), and similar odds of stroke/death with CEA (TCAR vs CEA: 0.7% vs 0.9%; aOR, 0.80; 95% CI, 0.16-3.98; P = .8). Compared with CEA, TCAR was associated with lower odds of postoperative MI (0.1% vs 14%; aOR, 0.02; 95% CI, 0.00-0.10; P < .001), stroke/death/MI (0.8% vs 15%; aOR, 0.05; 95% CI, 0.01-0.25; P < .001), and CNI (0.1% vs 3.8%; aOR, 0.04; 95% CI, 0.00-0.30; P = .002) in this patient population. In symptomatic patients, TCAR had an unacceptably elevated in-hospital stroke/death rate of 5.1%, with lower rates of CNI than CEA. We also found an increasing trend in the proportion of patients undergoing TCAR following prior ipsilateral carotid stenting (2016 to 2023: 14% to 41%), with a relative decrease in proportions of tfCAS (61% to 45%) and CEA (25% to 14%) (P < .001). CONCLUSIONS: In asymptomatic patients with prior ipsilateral CAS, TCAR was associated with lower odds of in-hospital stroke/death compared with tfCAS, with comparable stroke/death but lower postoperative MI and CNI rates compared with CEA. In symptomatic patients, TCAR was associated with unacceptably higher in-hospital stroke/death rates. In line with the postprocedure outcomes, there has been a steady increase in the proportion of patients with prior ipsilateral stenting undergoing TCAR over time.

Seven years of the transcarotid artery revascularization surveillance project, comparison to transfemoral stenting and endarterectomy.

OBJECTIVE: This study utilizes the latest data from the Vascular Quality Initiative (VQI), which now encompasses over 50,000 transcarotid artery revascularization (TCAR) procedures, to offer a sizeable dataset for comparing the effectiveness and safety of TCAR, transfemoral carotid artery stenting (tfCAS), and carotid endarterectomy (CEA). Given this substantial dataset, we are now able to compare outcomes overall and stratified by symptom status across revascularization techniques. METHODS: Utilizing VQI data from September 2016 to August 2023, we conducted a risk-adjusted analysis by applying inverse probability of treatment weighting to compare in-hospital outcomes between TCAR vs tfCAS, CEA vs tfCAS, and TCAR vs CEA. Our primary outcome measure was in-hospital stroke/death. Secondary outcomes included myocardial infarction and cranial nerve injury. RESULTS: A total of 50,068 patients underwent TCAR, 25,361 patients underwent tfCAS, and 122,737 patients underwent CEA. TCAR patients were older, more likely to have coronary artery disease, chronic kidney disease, and undergo coronary artery bypass grafting/percutaneous coronary intervention as well as prior contralateral CEA/CAS compared with both CEA and tfCAS. TfCAS had higher odds of stroke/death when compared with TCAR (2.9% vs 1.6%; adjusted odds ratio [aOR], 1.84; 95% confidence interval [CI], 1.65-2.06; P < .001) and CEA (2.9% vs 1.3%; aOR, 2.21; 95% CI, 2.01-2.43; P < .001). CEA had slightly lower odds of stroke/death compared with TCAR (1.3% vs 1.6%; aOR, 0.83; 95% CI, 0.76-0.91; P < .001). TfCAS had lower odds of cranial nerve injury compared with TCAR (0.0% vs 0.3%; aOR, 0.00; 95% CI, 0.00-0.00; P < .001) and CEA (0.0% vs 2.3%; aOR, 0.00; 95% CI, 0.0-0.0; P < .001) as well as lower odds of myocardial infarction compared with CEA (0.4% vs 0.6%; aOR, 0.67; 95% CI, 0.54-0.84; P < .001). CEA compared with TCAR had higher odds of myocardial infarction (0.6% vs 0.5%; aOR, 1.31; 95% CI, 1.13-1.54; P < .001) and cranial nerve injury (2.3% vs 0.3%; aOR, 9.42; 95% CI, 7.78-11.4; P < .001). CONCLUSIONS: Although tfCAS may be beneficial for select patients, the lower stroke/death rates associated with CEA and TCAR are preferred. When deciding between CEA and TCAR, it is important to weigh additional procedural factors and outcomes such as myocardial infarction and cranial nerve injury, particularly when stroke/death rates are similar. Additionally, evaluating subgroups that may benefit from one procedure over another is essential for informed decision-making and enhanced patient care in the treatment of carotid stenosis.

Outcomes following carotid revascularization for stroke stratified by Modified Rankin Scale and time of intervention.

OBJECTIVES: The relationship between baseline Modified Rankin Scale (mRS) in patients with prior stroke and optimal timing of carotid revascularization is unclear. Therefore, we evaluated the timing of transfemoral carotid artery stenting (tfCAS), transcarotid artery revascularization (TCAR), and carotid endarterectomy (CEA) after prior stroke, stratified by preoperative mRS. METHODS: We identified patients with recent stroke who underwent tfCAS, TCAR, or CEA between 2012 and 2021. Patients were stratified by preoperative mRS (0-1, 2, 3-4, or 5) and days from symptom onset to intervention (time to intervention; ≤2 days, 3-14 days, 15-90 days, and 91-180 days). First, we performed univariate analyses comparing in-hospital outcomes between separate mRS or time-to-intervention cohorts for all carotid intervention methods. Afterward, multivariable logistic regression was used to adjust for demographics and comorbidities across groups, and outcomes between the various intervention methods were compared. Primary outcome was the in-hospital stroke/death rate. RESULTS: We identified 4260 patients who underwent tfCAS, 3130 patients who underwent TCAR, and 20,012 patients who underwent CEA. Patients were most likely to have minimal disability (mRS, 0-1 [61%]) and least likely to have severe disability (mRS, 5 [1.5%]). Patients most often underwent revascularization in 3 to 14 days (45%). Across all intervention methods, increasing preoperative mRS was associated with higher procedural in-hospital stroke/death (all P < .03), whereas increasing time to intervention was associated with lower stroke/death rates (all P < .01). After adjustment for demographics and comorbidities, undergoing tfCAS was associated with higher stroke/death compared with undergoing CEA (adjusted odds ratio, 1.6; 95% confidence interval, 1.3-1.9; P < .01) or undergoing TCAR (adjusted odds ratio, 1.3; 95% confidence interval, 1.0-1.8; P = .03). CONCLUSIONS: In patients with preoperative stroke, optimal timing for carotid revascularization varies with stroke severity. Increasing preoperative mRS was associated with higher procedural in-hospital stroke/death rates, whereas increasing time to-intervention was associated with lower stroke/death rates. Overall, patients undergoing CEA were associated with lower in-hospital stroke/deaths. To determine benefit for delayed intervention, these results should be weighed against the risk of recurrent stroke during the interval before intervention.

Cutaneous Rosai-Dorfman disease with MAP2K1 mutation, initially mimicking an infection with parasitized histiocytes.

Rarely, Rosai-Dorfman disease (RDD) manifests exclusively in the skin, typically as nodules on the trunk and extremities. Recognition of characteristic histopathologic features enables diagnosis of RDD. A 55-year-old female presented with a 7-year history of cutaneous nodules involving the trunk and extremities. A prior skin biopsy specimen at a different institution had demonstrated a dense dermal lymphohistiocytic infiltrate with histiocytes containing GMS+ forms, favored to represent cryptococcal organisms, with a differential diagnosis including other infections with parasitized histiocytes. Despite antibiotic therapy, lesions persisted. After a presentation to our institution, a biopsy specimen showed a diffuse infiltrate, including histiocytes with voluminous pale cytoplasm with focal emperipolesis of inflammatory cells and S100 immunohistochemical positivity. Clinical and radiologic examinations did not identify significant extracutaneous involvement. A genetic study performed on the biopsy specimen identified a K57Q mutation of MAP2K1. The presence of this mutation correlated with prior reports of MAP2K1 mutation in classic RDD, thereby supporting our histopathologic diagnosis of RDD over an infectious process and further illuminating options for targeted therapies. At 3-year follow-up, the patient has been managed with a course of systemic corticosteroids and excision of bothersome lesions. Consideration of systemic therapy is ongoing.

Motivation When Desire Is Low: Associations Between Sexual Motivation and Sexual Intimacy, Sexual Satisfaction, and Sexual Distress for Men with Hypoactive Sexual Desire Disorder and Their Partners.

Hypoactive sexual desire disorder (HSDD) in men, characterized by chronically low sexual desire, is associated with poor sexual well-being, such as lower sexual satisfaction and higher sexual distress. Additionally, despite their low desire, men with HSDD often report wanting sexual intimacy and validation within their sexual lives/relationships. Studies that apply self-determination theory to sexual relationships demonstrate that adopting more autonomous (e.g., engaging in sex for its inherent pleasure) and less controlled (e.g., engaging in sex for some external reward or consequence) motives for engaging in sex is associated with greater sexual well-being for both members of the couple. Given that autonomous motivation in relationships is associated with intimacy and sexual satisfaction, and lower sexual distress, having sex for autonomous reasons may allow men with HSDD and their partners to feel more sexually intimate despite their lower sexual desire, whereas having sex for controlled reasons may hinder sexual intimacy and satisfaction and augment sexual distress. In this dyadic cross-sectional study, we examined the associations between types of sexual motivation and sexual intimacy, sexual satisfaction, and sexual distress for men with HSDD and their partners (n = 64 couples). Men with HSDD who reported having sex for more autonomous reasons reported more sexual satisfaction and both partners reported more sexual intimacy. Men with HSDD who had sex for more controlled reasons had partners who felt less sexual intimacy and satisfaction, and both partners were more sexually distressed. Promoting autonomous sexual motivation and decreasing controlled motivation may help couples navigating HSDD to feel closer in their relationship, more sexually satisfied, and less sexually distressed.

Characterization of Strokes following Gore Thoracic Branch Endografting requiring Zone 2 landing.

OBJECTIVES: The GORE® TAG® Thoracic Branch Endoprosthesis (TBE)is the only currently FDA-approved branched device for the treatment of thoracic aortic pathology requiring landing in Zone 2 in the US. While the aneurysm cohort disabling stroke rate in the pivotal trial has previously been reported, a more complete and granular description has not yet been published. This is a descriptive series detailing the neurologic sequelae from the pivotal trial, out to 12 months. METHODS: All patients underwent Modified Rankin Scale (MRS) assessment at screening, discharge, 1-, 6-, and 12-month intervals. A disabling stroke was defined as occurring within 30-days of the index procedure, combined with a MRS ≥2 with an increase from baseline of at least one grade. Descriptive statistics with important associations with aortic pathology, landing in native aorta versus Dacron graft, and intraoperative ballooning were noted. Further granularity with regard to the distribution and type of stroke are also reported, where available. RESULTS: A total of 238 patients were included in the pivotal trial. The treated aortic pathologies were: aneurysm (n=84), dissection (n=132), traumatic transection (n=9), other isolated lesions(n=13). Through 12 months, the overall stroke rate was 5.9%, with the highest rate of stroke in the aneurysm cohort (aneurysm-8.3%, dissection-4.6%, traumatic transection-0%, other-7.7%). The frequency of disabling strokes through 12 months were: aneurysm-4.3%, dissection-2.3%, other lesion-7.7%. Forty percent of strokes (n=6) occurred within 30 days and included both hemorrhagic (n=3) as well as ischemic (n=3) events. The distribution of strokes within 30 days included left carotid (n=1), posterior circulation (n=2), as well as unknown (n=3). The strokes occurring after 30 days were primarily ischemic (6/8), and included left carotid (n=2), right carotid (n=1), posterior circulation (n=1), posterior circulation and right carotid (n=1), posterior circulation and left and right carotid (n=1), and unknown location (n=1). The majority of patients suffering from stroke had aortic component landing in the native aortic arch, as well as ballooning of the aortic component (10/14). CONCLUSIONS: The TBE prosthesis is associated with comparable 30-day stroke rates to similar series of patients undergoing Zone 2 landing after debranching procedures. Stroke rates were highest in aneurysm pathology patients, with no strokes in the traumatic transection cohort. Perioperative strokes were hemorrhagic and ischemic, whereas those occurring after the perioperative period were primarily ischemic in nature. The distribution of stroke covered multiple territories, suggesting an embolic etiology. These data better define the neurologic risks associated with placement of this branched technology in the aortic arch.

Factors Associated with Urgent Amputation Status and Its Impact on Mortality.

BACKGROUND: Thirty-day mortality is higher after urgent major lower extremity amputations compared to elective lower extremity amputations. This study aims to identify factors associated with urgent amputations and to examine their impact on perioperative outcomes and long-term mortality. METHODS: Patients undergoing major lower limb amputation from 2013 to 2020 in the Vascular Quality Initiative were included. Urgent amputation was defined as occurring within 72 hr of admission. Associations with sociodemographic characteristics, comorbidities, and outcomes including postoperative complication, inpatient death, and long-term survival were compared using univariable tests and multivariable logistic regression. Long-term survival between groups was compared using Kaplan-Meier analysis. RESULTS: Of the 12,874 patients included, 4,850 (37.7%) had urgent and 8,024 (62.3%) had elective amputations. Non-White patients required urgent amputation more often than White patients (39.8% vs. 37.9%, P = 0.03). A higher proportion of Medicaid and self-pay patients presented urgently (Medicaid: 13.0% vs. 11.0%; self-pay: 3.4% vs. 2.5%, P < 0.001). Patients requiring urgent amputation were less often taking aspirin (55.6% vs. 60.1%, P < 0.001) or statin (62.2% vs. 67.2%, P < 0.001), had fewer prior revascularization procedures (41.0% vs. 48.8%, P < 0.001), and were of higher American Society of Anesthesiologists (ASA) class 4-5 (50.9% vs. 40.1%, P < 0.001). Urgent amputations were more commonly for uncontrolled infection (48.1% vs. 29.4%, P < 0.001) or acute limb ischemia (14.3% vs. 6.2%, P < 0.001). Postoperative complications were higher after urgent amputations (34.7% vs. 16.6%, P < 0.001), including need for return to operating room (23.8% vs. 8.4%, P < 0.001) and need for higher revision (15.2% vs. 4.5%, P < 0.001). Inpatient mortality was higher after urgent amputation (8.9% vs. 5.4%, P < 0.001). Multivariable analysis revealed non-White race, self-pay, homelessness, current smoking, ASA class 4-5, and amputations for uncontrolled infection or acute limb ischemia were associated with urgent status, whereas living in a nursing home or prior revascularization were protective. Furthermore, urgent amputation was associated with an increased odds of postoperative complication or death (odds ratio 1.86 [1.69-2.04], P < 0.001) as well as long-term mortality (odds ratio: 1.24 [1.13-1.35], P < 0.001). Kaplan-Meier analysis corroborated that elective status was associated with improvement of long-term survival. CONCLUSIONS: Patients requiring urgent amputations are more often non-White, uninsured, and less frequently had prior revascularization procedures, revealing disparities in access to care. Urgency was associated with a higher postoperative complication rate, as well as increased long-term mortality. Efforts should be directed toward reducing these disparities to improve outcomes following amputation.

Spinal fusion surgery use among adults with low back pain enrolled in a digital musculoskeletal program: an observational study.

OBJECTIVES: To compare 12-month spinal fusion surgery rates in the setting of low back pain among digital musculoskeletal (MSK) program participants versus a comparison cohort who only received usual care. STUDY DESIGN: Retrospective cohort study with propensity score matched comparison cohort using commercial medical claims data representing over 100 million commercially insured lives. METHODS: All study subjects experienced low back pain between January 2020 and December 2021. Digital MSK participants enrolled in the digital MSK low back program between January 2020 and December 2021. Non-participants had low back pain related physical therapy (PT) between January 2020 and December 2021. Digital MSK participants were matched to non-participants with similar demographics, comorbidities and baseline MSK-related medical care use. Spinal fusion surgery rates at 12 months post participation were compared. RESULTS: Compared to non-participants, digital MSK participants had lower rates of spinal fusion surgery in the post-period (0.7% versus 1.6%; p < 0.001). Additionally, in the augmented inverse probability weighting (AIPW) model, digital MSK participants were found to have decreased odds of undergoing spinal fusion surgery (adjusted odds ratio: 0.64, 95% CI: 0.51-0.81). CONCLUSIONS: This study provides evidence that participation in a digital MSK program is associated with a lower rate of spinal fusion surgery.

Association Between E-Cigarettes, Cognition and Mood in Adolescents.

OBJECTIVE: Research has indicated potentially neutral or even positive cognitive effects of e-cigarette usage in adults, but whether these findings extend to adolescents remains uncertain. This study aimed to examine the interplay between e-cigarette use, mind wandering and self-efficacy, and mood. METHOD: The responses of 432 adolescents aged 11-18 years from an online survey were analyzed. Among them, 88 adolescents had used e-cigarettes. RESULTS: Adolescents who have used e-cigarettes reported poorer academic self-efficacy, t (430) = 3.26, 95% CI [1.12, 4.51], p < 0.001; greater mind-wandering tendencies t(430) = -3.38, 95% CI [-4.14, -1.10], p < 0.001; and greater severity of depression, t(430) = -3.38, p < 0.001, anxiety t(430) = -2.67, p = 0.01, and stress t(430) = -3.32, p < .001. Increased frequency of e-cigarette use was also associated with attitudes toward e-cigarette use, r (86) = 0.31, p = 0.003 and lower academic self-efficacy, r (86) = -0.27, p = .010. However, there was no significant correlation between frequency of use and mind-wandering. Further network analysis suggested negative relationships between frequency of e-cigarette use, academic self-efficacy and mind-wandering. CONCLUSION: Our findings suggest a potential adverse impact of e-cigarette use on mind-wandering and academic confidence among adolescents. However, the direct or indirect relationship between e-cigarette use and these effects could not be definitively determined due to the cross-sectional survey design employed in our study. Nonetheless, our findings underscore the importance of considering developmental differences and the unique vulnerabilities of adolescents when assessing the impact of e-cigarette use.

2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease: A Report of the American Heart Association/American College of Cardiology Joint Committee on Clinical Practice Guidelines.

AIM: The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS: A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. Structure: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Racial Differences in Isolated Aortic, Concomitant Aortoiliac, and Isolated Iliac Aneurysms: This is a Retrospective Observational Study.

OBJECTIVE: Our aim was to describe the racial and ethnic differences in presentation, baseline and operative characteristics, and outcomes after aortoiliac aneurysm repair. SUMMARY OF BACKGROUND DATA: Previous studies have demonstrated racial and ethnic differences in prevalence of abdominal aortic aneurysms and showed more complex iliac anatomy in Asian patients. METHODS: We identified all White, Black, Asian, and Hispanic patients undergoing aortoiliac aneurysm repair in the VQI from 2003 to 2019. We compared baseline comorbidities, operative characteristics, and perioperative outcomes by race and ethnicity. RESULTS: In our 60,435 patient cohort, Black patients, followed by Asian patients, were most likely to undergo repair for aortoiliac (W:23%, B:38%, A:31%, H:22%, P < 0.001) and isolated iliac aneurysms (W:1.0%, B:3.1%, A:1.5%, H:1.6%, P < 0.001), and White and Hispanic patients were most likely to undergo isolated aortic aneurysm repair (W:76%, B:59%, A:68%, H:76%, P < 0.001). Black patients were more likely to undergo symptomatic repair and underwent rupture repair at a smaller aortic diameter. The iliac aneurysm diameter was largest in Black and Asian patients. Asian patients were most likely to have aortic neck angulation above 60 degree, graft oversizing above 20%, and completion endoleaks. Also, Asian patients were more likely to have a hypogastric artery aneurysm and to undergo hypogastric coiling. CONCLUSION: Asian and Black patients were more likely to undergo repair for aortoiliac and isolated iliac aneurysms compared to White and Hispanic patients who were more likely to undergo repair for isolated aortic aneurysms. Moreover, there were significant racial differences in the demographics and anatomic characteristics that could be used to inform operative approach and device development.

Impact of thoracic endovascular aortic repair timing on outcomes after uncomplicated type B aortic dissection in the Society for Vascular Surgery Vascular Quality Initiative postapproval project for dissection.

OBJECTIVE: The timing of thoracic endovascular aortic repair (TEVAR) after the onset of uncomplicated acute type B aortic dissection (uTBAD) remains controversial. The objective of this study was to evaluate the Society for Vascular Surgery Vascular Quality Initiative (VQI) postapproval study (VQI PAS) data for the impact of TEVAR timing for uTBAD on early and late outcomes, including mortality, procedural complications, and long-term reintervention. METHODS: The VQI PAS used for this analysis includes a total of 606 patients. Patients with uTBAD (defined as those without rupture or malperfusion) exclusive of cases categorized as emergent (N = 206) were divided into groups defined by the Society for Vascular Surgery/Society of Thoracic Surgeons reporting guidelines based on the timing of treatment after the onset of dissection: within 24 hours (N = 8), 1 to 14 days (N = 121), and 15 to 90 days (N = 77). Univariate and multivariable analysis were used to determine differences between timing groups for postoperative mortality, in-hospital complications, and reintervention. RESULTS: Demographics and comorbid conditions were very similar across the 3 TEVAR timing groups. Notable differences included a higher prevalence of baseline elevated creatinine (>1.8 mg/dL)/chronic end-stage renal disease and designation as "urgent" in the <24-hour group, as well as a higher rate of preoperative ß-blocker therapy in the 1- to 14-day group. Postoperative stroke, congestive heart failure, and renal ischemia were more common in the <24-hour group without an increase in mortality. Unadjusted 30-day mortality across groups was lowest in the early TEVAR group (0%, 3.3%, and 5.2%; P = .68), as was 1-year mortality (0%, 8.3%, and 18.2%; P = .06), although not statistically different at any time point. Reintervention out to 3 years was not different between the groups. Multivariable analysis demonstrated the need for a postoperative therapeutic lumbar drain to be the only a predictive risk factor for mortality (hazard ratio = 7.595, 95% confidence interval: 1.730-33.337, P = .007). When further subdivided into patients treated 1 to 7 days or 8 to 14 days after dissection, findings were similar. CONCLUSIONS: Patients with uTBAD treated within 24 hours were unusual (N = 8), too small for valid statistical comparison, and likely represent a high-risk subgroup, which is manifested in a higher risk of complications. Although there was a trend toward improved survival in the acute (1- to 14-day) phase, outcomes did not differ compared with the subacute (15- to 90-day) phase with relation to early mortality, postoperative complications, or 1-year survival. These data suggest that the proper selection of patients for early TEVAR can result in equivalent survival and early outcomes.

Impact of Medicaid expansion on outcomes after abdominal aortic aneurysm repair.

OBJECTIVE: Lack of insurance has been independently associated with an increased risk of in-hospital mortality after abdominal aortic aneurysm repair, possibly due to worse control of comorbidities and delays in diagnosis and treatment. Medicaid expansion has improved insurance rates and access to care, potentially benefiting these patients. We sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair. METHODS: A retrospective analysis of Healthcare Cost and Utilization Project State Inpatient Databases data from 14 states between 2012 and 2018 was conducted. The sample was restricted to first-record abdominal aortic aneurysm repairs in adults under age 65 in states that expanded Medicaid on January 1, 2014 (Medicaid expansion group) or had not expanded before December 31, 2018 (non-expansion group). The Medicaid expansion and non-expansion groups were compared between pre-expansion (2012-2013) and post-expansion (2014-2018) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors, open vs endovascular repair, and standard errors clustered by state. Our primary outcome was in-hospital mortality. Outcomes were stratified by insurance type. RESULTS: We examined 8995 patients undergoing abdominal aortic aneurysm repair, including 3789 (42.1%) in non-expansion states and 5206 (57.9%) in Medicaid expansion states. Rates of Medicaid insurance were unchanged in non-expansion states but increased in Medicaid expansion states post-expansion (non-expansion: 10.9% to 9.8%; P = .346; expansion: 9.7% to 19.7%; P < .001). One in 10 patients from both non-expansion and Medicaid expansion states presented with ruptured aneurysms, which did not change over time. Rates of open repair decreased in both non-expansion and Medicaid expansion states over time (non-expansion: 25.1% to 19.2%; P < .001; expansion: 25.2% to 18.4%; P < .001). On adjusted difference-in-differences analysis between expansion and non-expansion states pre-to post-expansion, Medicaid expansion was associated with a 1.02% absolute reduction in in-hospital mortality among all patients (95% confidence interval, -1.87% to -0.17%; P = .019). Additionally, among patients who were either on Medicaid or were uninsured (ie, the patients most likely to be impacted by Medicaid expansion), a larger 4.17% decrease in in-hospital mortality was observed (95% confidence interval, -6.47% to -1.87%; P < .001). In contrast, no significant difference-in-difference in mortality was observed for privately insured patients. CONCLUSIONS: Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients and particularly among patients who were either on Medicaid or were uninsured. Our results provide support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.
